Granulomatous-Lymphocytic Interstitial Lung Disease in 22q11.2 Deletion Syndrome: a Case Report and Literature Review

Abstract

Purpose of Review

Granulomatous-lymphocytic interstitial lung disease (GLILD) has classically been associated with common variable immune deficiency (CVID), but is increasingly being reported in other immunodeficiencies. We describe the second reported case of GLILD in a patient with 22q11.2 deletion syndrome (22q11.2DS) and review the recent literature surrounding GLILD.

Recent Findings

GLILD is characterized by granulomata and lymphoproliferation. Consensus statements and retrospective and case-control studies have better elucidated the clinicopathological and radiographic manifestations of GLILD, allowing for its differentiation from similar conditions like sarcoidosis. Gaps of knowledge remain, however, particularly regarding optimal management strategies. Combination therapies targeting T and B cell populations have recently shown favorable results.

Summary

GLILD is associated with poorer outcomes in CVID. Its recognition as a rare complication of 22q11.2DS and other immunodeficiencies therefore has important therapeutic and prognostic implications. Additional research is needed to better understand the natural history and pathogenesis of GLILD and to develop evidence-based practice guidelines.

The Effect of Inhalant Organic Dust on Bone Health

Abstract

Purpose of Review

Agriculture remains a major economic sector globally, and workers experience high rates of chronic inflammatory lung and musculoskeletal diseases. Whereas obstructive pulmonary diseases are known risk factors for bone loss, the underlying relationship between lung inflammation and bone health is not well known.

Recent Findings

An agriculture organic dust extract inhalation animal model has recently linked lung injury-induced inflammation to systemic bone loss. This process is dependent upon lipopolysaccharide and the toll-like receptor 4 (TLR4) signaling pathway. Downstream systemic interleukin-6 is a key mediator that subsequently activates osteoclastogenesis. Age is a host factor that impacted bone disease with younger mice demonstrating increased susceptibility to bone loss following inhalant exposures as compared to older mice. Supplemental dietary vitamin D was shown to prevent organic dust-induced bone loss, but not lung disease, in animals.

Summary

Recent animal studies provide new mechanistic insight into the lung-bone inflammatory axis. Host factors, diet, and lipopolysaccharide/TLR4 signaling pathways play a significant role in explaining how inhalant organic dust exposures impact bone health. These investigations might lead to specific targeted therapeutic approaches.

Current Status of Potential Therapies for IgE-Mediated Food Allergy

Abstract

Purpose of Review

The goal of this review is to provide the reader with an updated summary of published trial data regarding the use of oral immunotherapy (OIT), sublingual immunotherapy (SLIT), and epicutaneous immunotherapy (EPIT) for treatment of IgE-mediated food allergies.

Recent Findings

Data from phase 2 trials for treatment of peanut allergy with OIT and EPIT reveal an increase in the threshold of reactivity for peanut-allergic children. Compared to EPIT, OIT promotes a greater increase in the threshold of reactivity; however, adverse events are more common with OIT.

Summary

OIT, EPIT, and SLIT appear to modulate the immune response for some food-allergic individuals. Data regarding utility for treatment of food allergies regardless of modality is limited to few foods, as is investigation into treatment of food-allergic infants, young children, and adults. Future trials are likely to focus on young children, food allergies other than peanut, and treatment of multifood-allergic individuals.

Diagnostic Tools for Inborn Errors of Human Immunity (Primary Immunodeficiencies and Immune Dysregulatory Diseases)

Abstract

Purpose of Review

The purpose of this review is to provide an overview of diagnostic testing in primary immunodeficiency and immune dysregulatory disorders (PIDDs), particularly focusing on flow cytometry and genetic techniques, utilizing specific examples of PIDDs.

Recent Findings

Flow cytometry remains a vital tool in the diagnosis and monitoring of immunological diseases. Its utility ranges from cellular analysis and specific protein quantitation to functional assays and signaling pathway analysis. Mass cytometry combines flow cytometry and mass spectrometry to dramatically increase the throughput of multivariate single-cell analysis. Next-generation sequencing in combination with other molecular techniques and processing algorithms has become more widely available and identified the diverse and heterogeneous genetic underpinnings of these disorders.

Summary

As the spectrum of disease is further clarified by increasing immunological, genetic, and epigenetic knowledge, the careful application of these diagnostic tools and bioinformatics will assist not only in our understanding of these complex disorders, but also enable the implementation of personalized therapeutic approaches for disease management.

Indoor Environmental Interventions and their Effect on Asthma Outcomes

Abstract

Purpose of Review

The use of environmental interventions to improve outcomes in asthmatics has long been an elusive goal. While numerous interventions have been studied, the results of clinical trials have been mixed. This review aims to identify combinations of interventions that have been proven to be effective and to propose a model for using them in a clinical setting.

Recent Findings

An NIH workshop emphasized a need for research to identify effective interventions for reducing indoor exposures and improving asthma outcomes. A number of innovative measures were described, though evidence supporting their use was lacking. A recent systematic review described various interventions for which evidence is available. The greatest challenge for this approach is the same as that for the medical approach to treatment: nonadherence.

Summary

Given evidence for effective interventions, control of environmental exposures should lead to improved asthma outcomes. Methods to improve adherence need to be identified.

Impact of Particulate Air Pollution on Cardiovascular Health

Abstract

Purpose of Review

Air pollution is established as an independent risk factor for cardiovascular diseases (CVDs). Ambient particulate matter (PM), a principal component of air pollutant, has been considered as a main culprit of the adverse effects of air pollution on human health.

Recent Findings

Extensive epidemiological and toxicological studies have demonstrated particulate air pollution is positively associated with the development of CVDs. Short-term PM exposure can trigger acute cardiovascular events while long-term exposure over years augments cardiovascular risk to an even greater extent and can reduce life expectancy by a few years. Inhalation of PM affects heart rate variability, blood pressure, vascular tone, blood coagulability, and the progression of atherosclerosis. The potential molecular mechanisms of PM-caused CVDs include direct toxicity to the cardiovascular system or indirect injury by inducing systemic inflammation and oxidative stress in circulation.

Summary

This review mainly focuses on the acute and chronic effects of ambient PM exposure on the development of cardiovascular diseases and the possible mechanisms for PM-induced increases in cardiovascular morbidity and mortality. Additionally, we summarized some appropriate interventions to attenuate PM air pollution-induced cardiovascular adverse effects, which may promote great benefits to public health.

Author(s): Joseph Zenga, Jennifer Gross, Susan Fowler, Jenny Chen, Peter Vila, Jeremy D. Richmon, Mark A. Varvares, Patrik Pipkorn
PurposeTo determine the oncologic and functional outcomes of patients undergoing salvage surgery for recurrent head and neck squamous cell carcinoma after initial management with surgery and adjuvant therapy.Data sourcesOvid Medline, Embase, Scopus, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, Cochrane Database of Systematic Reviews, and Clinicaltrials.gov.Review methodsA structured search was performed of the literature to identify studies that included patients undergoing surgical salvage for local, regional, or locoregional recurrent head and neck squamous cell carcinoma without known distant metastases who had been treated with initial surgery and post-operative adjuvant radio- or chemoradiotherapy. Studies were excluded if they did not report at least 1-year survival estimates, included patients who underwent primary non-surgical management, or included those treated with non-surgical salvage therapies or supportive care alone.ResultsThe search strategy yielded 3746 abstracts. After applying exclusion and inclusion criteria, 126 full-texts were reviewed and six studies were included with a total of 222 patients. All studies were retrospective in design and included diverse disease subsites and stages. Complications and functional outcomes were inconsistently reported. Five-year survival estimates ranged between 10% and 40% between studies.ConclusionsPatients undergoing salvage surgery for recurrent head and neck squamous cell carcinoma after initial surgery and adjuvant therapy may have a particularly poor prognosis. Future studies are needed to determine functional and quality of life outcomes in this patient population and to identify specific prognostic factors for re-recurrence and survival.

BackgroundLeiomyosarcoma of the head and neck region is very rare. Primary parotid leiomyosarcoma has only been reported nine times in the medical literature.MethodsA 68-year-old female presented with a left facial mass. Physical examination revealed a firm immobile mass at the level of the left parotid tail. No facial nerve dysfunction or palpable adenopathy was noted at the time of presentation. This patient underwent a superficial parotidectomy with a facial nerve dissection and left selective neck dissection.ResultsPathologic findings revealed a sarcoma of intermediate to high-grade, composed of spindle cells with herringbone pattern, eosinophilic fibrillary cytoplasm, and focal granularity. Immunohistochemistry was positive for vimentin and smooth muscle actin and negative for desmin, S100 and CD34. The findings are consistent with a leiomyosarcoma. Following complete surgical resection, adjuvant radiation therapy was administered.ConclusionPrimary sarcomas of the parotid gland, specifically parotid leiomyosarcomas, are extremely rare. Based on this patient's tumor size, grade and resectability, this case met the criteria for a primary leiomyosarcoma. We present only the tenth case of a primary parotid leiomyosarcoma to be reported in the English literature.

ObjectiveWhile hearing loss following temporal bone fracture is a well-described phenomenon, few data exist on auditory dysfunction in patients with traumatic brain injury (TBI) without temporal bone fracture. Herein, we aim to systematically review hearing loss after TBI without bony fracture and describe its etiologies.Data sourcesPubmed, Embase, Cochrane databases.Review methodsA systematic review of the literature from 1966 to January 2017 was performed using Preferred Reporting Items for Systematic Reviews and Meta-analyses recommendations. Data were obtained from studies that investigated hearing loss in TBI without skull fracture according to an a priori protocol with inclusion and exclusion criteria. Variables included type and severity of hearing loss, as well as pathophysiology of hearing loss.ResultsThere were 13 studies with 773 patients that met study criteria. Overall, there was one prospective cohort study, four retrospective cohort studies, two case-control studies, and six case reports. The studies with the highest level of evidence report a change in hearing of at least 10–15 dB across a range of frequencies in as many as 58% percent of TBI patients without bony fracture, which was transient or chronic. The mechanism/severity of injury may impact the rate of hearing loss.ConclusionsHearing loss after TBI in the absence of bony injury appears to be a clinically significant but poorly characterized phenomenon.

PurposeTo evaluate the prognostic significance of human papillomavirus (HPV) status among patients treated by salvage radiation therapy for local-regional recurrences and second primary cancers of the head and neck arising in a previously irradiated field.Methods and materialsThe medical records of 54 consecutive patients who underwent re-irradiation for squamous cell carcinoma of the head and neck occurring in a previously irradiated field were reviewed. Only patients with biopsy-proven evidence of recurrent disease that had previously been treated with doses of radiation therapy of at least 60 Gy were included. Determination of HPV status at the time of recurrence was performed by p16 immunohistochemistry. The median age at re-irradiation was 58.5 years (range, 27.9 to 81.5 years). Thirty patients (55.5%) were lifelong never-smokers. The Kaplan Meier method was used to calculate overall survival, progression-free survival, and local-regional control, and distant metastasis-free survival with comparisons between groups performed using the log-rank test.ResultsHPV status among tumors that were re-irradiated was as follows: 16 positive (29.7%); 7 negative (12.9%); 31 unknown (57.4%). The median overall survival in the entire cohort was 11.7 months (range, 8 to 27 months), with the 1-year and 2-year estimates of overall survival being 47.2% and 38.4%, respectively. A statistical trend was identified favoring patients with HPV-positive cancers with respect to the endpoints of overall survival (p = 0.06) and progression-free survival (p = 0.08) after re-irradiation when compared to the HPV-negative/unknown population. There was no significant difference in distant control between the two cohorts (p = 0.40).ConclusionsThe favorable prognostic significance of HPV seemingly extends to patients treated by re-irradiation suggesting that this biomarker may be useful in risk stratification in this setting.

Author(s): Sameep Kadakia, Ameya Jategaonkar, Ansley Roche, Raymond L. Chai
Eagle Syndrome can present with a variety of symptoms and be caused by an elongated styloid process or calcified stylohyoid ligament. Patients failing medical management of this disorder may be treated with surgical excision of the styloid process. In the literature, transoral and transcervical approach have both been described. Although transoral approaches typically begin with a tonsillectomy, tonsil-sparing approaches have also been utilized. With the advent of robotic surgery, the potential for a tonsillectomy sparing approach has become a feasible alternative, preventing the pain and morbidity associated with adult tonsillectomy while continuing to provide superior exposure and instrumentation. We report three successful cases of patients treated with tonsillectomy sparing transoral robot assisted styloidectomy. This represents the first application of this technique in the literature and suggests the potential for a paradigm shift in the surgical management of this disease.

Author(s): Nicholas B. Abt, Rosh K. Sethi, Sidharth V. Puram, Mark A. Varvares
Objectives1) Describe normal/abnormal preoperative laboratory testing incidence in head and neck (H&N) composite resections and 2) determine complication, surgical site infection (SSI), and transfusion predictors by laboratory test.MethodsThe 2006 to 2013 NSQIP databases were queried for H&N composite resections. Laboratory data was categorized within, under, or above the normal reference range according to NSQIP definitions. Overall complications and SSI were analyzed with multivariable logistic regression analysis.ResultsFrom 2006 to 2013, there were 1193H&N composite resections, of which 1135 (95.1%) underwent ≥1 preoperative laboratory test. Complete blood counts were obtained in 92.3%, basic metabolic panels in 90.7%, coagulation studies in 56.2%, and liver function tests (LFTs) in 52.6%. Low sodium was found in 11.5%, increasing complication odds by 2.30 (p = 0.005). High AST comprised 10.0% and increased complication odds (OR = 2.93, p = 0.012). Additionally, 9.2% had a high white blood cell (WBC) count and 3.5% had high platelets, increasing complications by 1.92 (p = 0.030) and 3.13 (p = 0.015), respectively. BUN, creatinine, total bilirubin, albumin, alkaline phosphatase, INR, PT, and aPTT abnormal values did not affect postoperative complications. Increased SSI odds were appreciated with low sodium (OR: 2.83, p = 0.002), high AST (OR: 6.85, p < 0.001), and high alkaline phosphatase (OR: 5.46, p = 0.007). Importantly, INR had no effect on transfusion rates. High PT, aPTT, or low platelets did not change transfusion odds.ConclusionInflammatory markers are associated with complications but not SSI. High LFTs and low sodium are associated with complications and SSI. Coagulopathies did not increase transfusion rates. These findings identify laboratory studies to focus on during H&N resection preoperative assessments.

PurposeIn this article, a simple, new laryngeal suspension procedure is described. The effect of hyoid bone suspension by suturing the digastric muscle to the periosteum of the mandible is analyzed.Materials and methodsTo elucidate the effect of hyoid bone suspension, CT scans of 26 patients who underwent ipsilateral neck dissection with primary resection of tongue cancer were retrospectively reviewed, and the distance between the hyoid bone and the mandible was measured on the operated and unoperated sides of the neck. A total of 14 patients who underwent suturing of the digastric muscle to the mandible (digastric muscle-sutured group) and the 12 patients who did not (control group) were compared.ResultsIn the digastric muscle-sutured group, the average distance between the hyoid bone and the mandible was significantly smaller on the operated side (17.8 ± 0.57 mm) than on the unoperated side (19.8 ± 0.93 mm; p < 0.05). In the control group, there was no significant difference between the operated side (21.0 ± 1.42 mm) and the unoperated side (19.7 ± 1.39 mm). The difference in the distance between the operated and unoperated sides was significantly larger in the digastric muscle-sutured group (1.97 ± 0.79 mm) than in the control group (−1.32 ± 0.61; p < 0.05).ConclusionsIt was shown for the first time that suturing of the digastric muscle to the periosteum of the mandible in neck dissection with primary resection of tongue cancer resulted in hyoid bone suspension. This simple procedure can be useful for laryngeal suspension.

Author(s): Adam M. Kravietz, Jessica L. Buicko, Joshua P. Parreco, Michael A. Lopez, Robert A. Kozol
PurposeParathyroidectomy is one of the most common procedures performed in the United States, and are increasingly being performed safely in the outpatient setting. However, complications from surgery can be life-threatening, and thus an understanding of who may be at risk is essential. We analyzed and compared the risk factors for patients readmitted within 30 days following inpatient parathyroidectomy for primary or secondary hyperparathyroidism.Materials and methodsWe reviewed the National Readmissions Database from 2013 to 2014 for patients who received inpatient parathyroidectomy for primary or secondary hyperparathyroidism. The primary outcome was non-elective readmission within 30 days. Multivariate logistic regression was used to analyze risk factor odds ratios for readmission.Results7171 patients underwent inpatient parathyroidectomies in 2013 and 2014. 59.89% of parathyroidectomies were performed for primary hyperparathyroidism, with a 5.6% readmission rate. Most common causes of readmission were septicemia (13.69%), hypocalcemia (12.86%), heart failure (10.79%) and renal failure (9.54%). Having Medicare (OR: 1.71, CI:1.14–2.59, p = .01), Medicaid (OR: 3.24, CI: 2.03–5.17, p < .001), and self-paying (OR: 2.43, CI: 1.11–5.32, p = .02), were associated with increased odds of readmission for those with primary hyperparathyroidism. 21.99% of parathyroidectomies were performed for secondary hyperparathyroidism, with a 19.4% readmission rate. Most common causes of readmission were hypocalcemia (22.88%), hungry bone syndrome (14.38%), electrolyte disorders (13.73%), and renal failure (11.11%).ConclusionPatients with secondary hyperparathyroidism are older, poorer and have more comorbidities than patients with primary hyperparathyroidism, and are more likely to be readmitted within 30 days of parathyroidectomy.

Paediatric Autoimmune Neuropsychiatric Disorder Associated with Group A Beta-Haemolytic Streptococcal Infection: An Indication for Tonsillectomy? A Review of the Literature

Background. Paediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infection (PANDAS) is the acute onset of neuropsychiatric symptoms following group A beta-haemolytic streptococcal infection. The aetiology remains elusive. However, with group A streptococcus being the most common bacterial cause of tonsillitis, surgical intervention in the form of tonsillectomy has often been considered as a potential therapy. Methods. A MEDLINE® search was undertaken using keywords "PANDAS" or "paediatric autoimmune neuropsychiatric disorders associated with streptococcus" combined with "tonsillectomy". Results. Six case reports and 3 case series met the inclusion criteria. Demesh et al. (case series) reported a dramatic reduction in neuropsychiatric symptom severity in the patient cohort undergoing tonsillectomy. Two case series suggest that there is no association between tonsillectomy and resolution of PANDAS. Conclusion. Due to the lack of uniform data and sporadic reports, tonsillectomy should be carefully adopted for the treatment of this disorder. In particular, tonsillectomies/adenoidectomies to alleviate neuropsychiatric symptoms should be avoided until more definitive evidence is at our disposal. This review highlights the importance of a potential collaborative prospective study.

Author(s): Daniel H. Coelho, Taylor S. Pence, Mostafa Abdel-Hamid, Richard M. Costanzo
ObjectiveAll successful endonasal surgery, including functional endoscopic sinus surgery (FESS), depends on knowledge of both anatomy and the specific variations that can occur between and within patients. Familiarity with these structures is a critical component in preventing complications from these procedures, and failure to understand subtle variation can have disastrous results. The aim of this study was to characterize the anatomical variations (if any) of the cribriform plate using a large cadaveric sample set. Better understanding of the disparities within and between patients may have important implications for surgical planning.MethodsWhole human skull specimens (31 specimens, 62 sides) were examined to obtain dimensional measurements of the cribriform plate on the right and left sides.ResultsThe average length of the cribriform plate was 21.28mm (range 15.25–27.73mm, SD 3.30mm). The average width of the cribriform plate (including the crista galli) was 4.53mm (range 1.75–8.03mm, SD 1.20mm). When comparing side differences in individual specimens, there was more variability between widths, relative standard deviation 26.4%, than between lengths, relative standard deviation 15.5%.ConclusionThere is a range of both length and width of the cribriform plate, between and within individuals. This is particularly true for width. In practice, this emphasizes the importance of pre-operative imaging and recognition of anatomic variability for sinus or anterior skull base procedure.

Author(s): Giandomenico Maggiore, Maria Silvia Lazio, Oreste Gallo
Olfactory neuroblastoma is a rare malignant tumor of neuroectodermal origin and represents the most common cancer of the nasal cavity in pediatric age. The gold standard of treatment consists of en bloc resection, numerous studies have shown as the endoscopic approaches permit good control of the disease improving the quality of life after the treatment. Herein we describe the case of a 13-year-old patient referred to our outpatient clinic with a polypoid multi-lobed lesion occupying the left nasal cavity and imaging that confirmed a left-sided nasal mass without cribriform plate involvement (Kadish B). We performed an unilateral endoscopic resection with transnasal craniectomy and anterior skull base reconstruction with a flap from the contralateral nasal septum based on the septal branches of the anterior and posterior ethmoidal arteries (Septal Flip Flap, SFF), that provided a faster healing process with reduction of nasal crusting, improvement in the quality of life of patient in the postoperative period and the preservation of the contralateral olfactory bulb that has allowed to save the smell. This treatment strategy of pediatric esthesioneuroblastoma was analyzed in the context of the current literature.

Combined transoral–transhyoid endoscopic approach for hypopharyngeal cancer

Publication date: Available online 3 February 2018

Author(s): Keigo Honda, Makoto Miura, Yasuyuki Hayashi, Toshiya Kimura
Endoscopic transoral surgery for hypopharyngeal cancer is an effective treatment option to avoid invasive open surgery or chemoradiation. Here we describe the case of a 66-year-old patient with cT2N0M0 pyriform sinus cancer whom we treated using a transoral–transhyoid endoscopic approach. Using this approach, a transhyoid route was created in addition to the transoral route and used to extirpate the tumor. En bloc resection of the tumor was completed without difficulty. A combined transoral–transhyoid approach is a useful surgical option for treatment of selected patients with hypopharyngeal cancer. This technique is straightforward to perform and can be used as a backup technique in endoscopic transoral surgery. Also, more complicated lesions can be resected by this approach than by a single-route transoral approach.

Facial nerve anomalies are a potential problem in patients with cochleovestibular malformations. A case of cochlear implant (CI) surgery in the presence of intra-temporalbone facial nerve bifurcation is presented. During the first surgery, the facial nerve bifurcation obscured the promontory and round window. It was difficult to perform cochleostomy because of the lack of landmarks of the basal turn of the cochlea, and the first surgical attempt at cochleostomy was abandoned. A repeat CT scan was performed after the first surgery with reconstructed 3D images of the temporal bone and the cochlea, and then the cochlea was successfully opened at revision surgery. Reconstructed 3D CT images were very useful to identify the site of cochleostomy in this case with such difficult temporal bone anatomy.

ObjectiveThe incidence of refractory chronic rhinosinusitis (CRS) associated with methicillin-resistant Staphylococcus aureus (MRSA) is rising and remains a therapeutic challenge. The goal of this study is to demonstrate the efficacy of a non-invasive topical therapy against MRSA in these patients.MethodsSeventeen patients with refractory CRS caused by MRSA were treated with a topical therapy protocol. Treatment consisted of weekly endoscopic sinus debridement followed by intra-sinus installation of a hydroxyl-ethylcellulose gel that releases mometasone and a culture-directed antibiotic for a period of 6 weeks, along with daily nasal nebulization of mometasone with the same antibiotic and saline rinses. Clinical outcome was assessed using the Lund–Kennedy (LK) symptom and endoscopic appearance scores. Sinus mucosal tissue was homogenized and cultured, and microbial biofilm burden was assessed based on colony forming units (CFUs) counts.ResultsRhinotopic therapy resulted in clearance of MRSA in 13 of 16 patients (81.2%). Treated patients also demonstrated significant improvement clinically as measured by the LK scores. In addition, a significant decrease in mucosal CFUs was observed post-therapy.ConclusionOur findings demonstrate that topical therapy is an effective method for treating MRSA-associated refractory CRS.

Author(s): Hironobu Nishijima, Sayaka Suzuki, Kenji Kondo, Tatsuya Yamasoba, Shintaro Yanagimoto
ObjectiveNumerous studies have reported that various environmental factors during early life are key determinants for developing allergic disease. Herein, we aimed to investigate the impact of environmental factors on allergic rhinitis.MethodsThis cross-sectional study was conducted in a single university in Japan (from April to June, in 2015 and 2016). Students voluntarily answered online questionnaires regarding their allergic rhinitis symptoms and their exposure to various environmental factors during preschool-age.ResultsOverall, 3075 students participated the questionnaire. After excluding those with incomplete datasets, 3016 students were eligible. Of these, 49% had allergic rhinitis symptoms. Female sex was associated with a lower risk of allergic rhinitis symptoms (odds ratio [OR], 0.82; 95% confidence interval [CI], 0.68–0.99). Comorbidity of asthma or atopic dermatitis and a family history of allergy (asthma, atopic dermatitis, or allergic rhinitis) were associated with higher risks of allergic rhinitis symptoms. Regarding the number of household members, compared with subjects with <3 people, those with 5 (OR, 0.74; 95% CI, 0.57–0.97) and ≥6 people (OR, 0.66; 95% CI, 0.49–0.88) in their household showed lower incidences of allergic rhinitis symptoms. No other environmental factors, including birth order, number of siblings, living environment, passive smoking, furry pet ownership, housing, bedding, breastfeeding, dairy product intake, preschool setting, and starting age of preschool, was associated with the incidence of allergic rhinitis symptoms.ConclusionSex, current asthma and atopic dermatitis symptoms, family history of allergies, and the number of people in the household at preschool-age were associated with the incidence of allergic rhinitis symptoms.

ObjectiveThe aim of this cohort was to determine potential risk factors, concerning the effectiveness of adenoidectomy in the treatment of chronic otitis media with effusion in children.MethodsNinety six children with chronic otitis media with effusion treated with adenoidectomy were enrolled in this study. A thorough medical history was taken, including family history of otologic disease, parental smoking habits and breast feeding history. Radiographic palatal airway size was measured preoperatively, whereas the presence of allergy was also investigated. All patients were, postoperatively, followed up for a period of two years, in three month intervals. Disease course was classified as "complete remission", "improvement" or "consistence", in every postoperative evaluation, according to strictly established criteria.ResultsChildren's age proved to be a significant factor in the postoperative outcome of adenoidectomy, as a treatment of chronic otitis media with effusion, especially when comparing patients being over and under the fifth year of age. Also, the presence of allergy, family history of otologic disease and palatal airway size, all proved to influence postoperative outcome in a statistical significant way (p<0.05). On the other hand, child's sex, passive smoking, breast feeding and previous acute otitis media infections did not seem to alter the efficacy of adenoidectomy.ConclusionAdenoidectomy remains a cornerstone in the treatment of chronic otitis media with effusion in children. Results document that young age, presence of allergy predisposition, otologic family history and small palatal airway can be important drawbacks and should be intensively sought for and taken into account, during treatment planning.

ObjectiveWhen the thresholds for VR reconstruction from multi-slice CT images are changed, problems develop when assessing pathologies in the absence of standardized thresholds. The advantages of CBCT include lower radiation exposure compared with other techniques and better visualization of small ear structures. However, a disadvantage is that the scanner provides unstandardized gray scale values, thus not CT numbers (Hounsfield units, HU).MethodsWe analyzed 88 sets of volume data obtained from temporal bones. The gray scale values were measured in aerated areas (two sites), along the ossicular chain (four sites) and in a bone area (one site) in the external and middle ears, and in soft tissue areas (five sites) and bone areas (two sites) in the inner ear.ResultsThe standard male and female gray scale values were 2448–2970 and 2585–3091 for the aerated areas, 3248–4945 and 3359–5223 for the ossicular chains, 3368–4109 and 3371–4147 for soft tissues, and 4790–5776 and 5044–5959 for bone, respectively. Sex significantly affected the values (p<0.05). Significant differences between aerated areas and ossicular chains, and between soft tissues and bone, were evident (all p<0.0001).ConclusionVolume-rendering (VR) images obtained by cone-beam computed tomography (CBCT) can be standardized simply by using fixed thresholds.

Author(s): Young Min Hah, Sang Hoon Kim, Junyang Jung, Sung Su Kim, Jae Yong Byun, Moon Suh Park, Seung Geun Yeo
ObjectiveThis study was designed to evaluate the prognostic value of the blink reflex (BR) test in patients with Bell's palsy (BP) or Ramsay Hunt syndrome (RHS).MethodsThe House–Brackmann (HB) grade of patients diagnosed with BP and RHS was determined at first visit and 3 months later. Final HB grade III–VI was defined as an incomplete recovery. Factors evaluated as prognostic of poor recovery included electroneurography (ENoG) degeneration rate (DR)>90%, and absence of BR. Rates of complete and incomplete recovery were calculated and the associations between prognostic factors and recovery were determined.ResultsOf the 129 included patients, 98 (76%) had BP and 31 (24%) had RHS. Absence of BR and low mean ENoG value were significantly associated with incomplete recovery in both the BP and RHS groups (p<0.05 each). Initial HB grade V–VI was significantly associated with rate of incomplete recovery in patients with RHS (p<0.05 each). Severe residual palsy (final HB grade V–VI) in the absence of BR was significantly more frequent in patients with RHS than with BP (p<0.05).ConclusionBR test results were a good prognostic indicator in patients with BP and RHS, as were ENoG value. Absence of BR was more frequently associated with severe residual palsy in RHS than in BP.

Facial Asymmetry: Brow and Ear Position

Facial plast Surg
DOI: 10.1055/s-0038-1636903

The purpose of the current study was to analyze brow and ear position, and examine the relationship between these structures in patients presenting for blepharoplasty evaluation. A retrospective chart review was performed, which included all patients presenting to one oculoplastic physician for a blepharoplasty evaluation from November, 2012 to March, 2014. The prevalence of brow ptosis and brow and ear asymmetry was calculated; the proportional distribution was determined, and chi-square analysis and the z-test of proportions were used to calculate the significance. Institutional Review Board approval was obtained for this study. A total of 133 patients met the inclusion criteria. Some degree of brow ptosis was noted in 83% of patients. Brow asymmetry was found in 88% of patients, and ear asymmetry in 77%. Of those patients who had asymmetry, 61% had the right brow lower and 75% had the right ear lower; 73% of all patients had the brow and ear lower on the same side (p < 0.001). In this study, brow ptosis and asymmetry were quite common. In addition, the side of the lower brow correlated strongly with the side of the lower ear, and the right side structures were lower more often than the left. Patients presenting for blepharoplasty evaluation may have an element of generalized facial asymmetry which includes the brows and ears. These observations can be important for preoperative planning and patient counseling.

Antitumor in situ vaccination effect of TNFα and IL-12 plasmid DNA electrotransfer in a murine melanoma model

Abstract

Gene electrotransfer (GET) is one of the most efficient non-viral gene therapy approaches for the localized transfer of multiple genes into tumors in vivo; therefore, it is especially promising for delivering different cytokines that are toxic if administered systemically. In this study, we used concomitant intratumoral GET of two cytokines: tumor necrosis factor alpha (TNFα), a potent cytotoxic cytokine to induce in situ vaccination, and interleukin 12 (IL-12), an immunostimulatory cytokine to boost the primed local immune response into a systemic one. After performing GET in murine melanoma tumors, both TNFα and IL-12 mRNA levels were significantly increased, which resulted in a pronounced delay in tumor growth of 27 days and a prolonged survival time of mice. An antitumor immune response was confirmed by extensive infiltration of immune cells in the tumor site, and expansion of the effector immune cells in the sentinel lymph nodes. Furthermore, the effect of in situ vaccination was indicated by the presence of vitiligo localized to the treatment area and resistance of the mice to secondary challenge with tumor cells. Intratumoral GET of two cytokines, one for in situ vaccination and one for an immune boost, proved feasible and effective in eliciting a potent and durable antitumor response; therefore, further studies of this approach are warranted.

Demographic characteristics of craniosynostosis patients in Asia

Craniosynostosis (CRS) is a congenital condition resulting premature fusion of one or more cranial sutures. CRS is classified according to the involved sutures into sagittal, metopic, unicoronal, unilambdoid, bicoronal, and multiple-suture CRS, with sagittal suture fusion known to be the most common type. Although multiple studies have presented demographic characteristics of CRS patients, to date, there is no study representing an Asian population. We sought to compare the demographic characteristics of Asian patients to those of Western patients, considering previous reports.

The BCR-ABL inhibitor nilotinib influences phenotype and function of monocyte-derived human dendritic cells

Abstract

In chronic myeloid leukemia (CML), the translocation t(9;22) results in the fusion protein BCR-ABL (breakpoint cluster region-abelson murine leukemia), a tyrosine kinase mediating oncogenic signaling which is successfully targeted by treatment with BCR-ABL inhibitors like imatinib. However, BCR-ABL inhibitors may also affect antitumor immunity. For instance, it was reported that imatinib impairs the function of dendritic cells (DCs) that play a central role in initiating and sustaining T cell responses. Meanwhile, second generation BCR-ABL inhibitors like nilotinib, which inhibits BCR-ABL with enhanced potency have become standard of treatment, at least in patients with BCR-ABL kinase domain mutations. In this study we analyzed the influence of therapeutic concentrations of nilotinib on human monocyte-derived DCs and compared its effects to imatinib. We found that both tyrosine kinase inhibitors (TKI) comparably and significantly impaired differentiation of monocytes to DCs as revealed by curtated downregulation of CD14 and reduced upregulation of CD1a and CD83. This was only partially restored after withdrawal of the TKI. Moreover, both TKI significantly reduced activation-induced IL-12p70 and C-C motif chemokine ligand (CCL) 3 secretion, while divergent TKI effects for CCL2 and CCL5 were observed. In contrast, only nilotinib significantly impaired the migratory capacity of DCs and their capacity to induce T-cell immune responses in MLRs. Our results indicate that imatinib and nilotinib may differ significantly with regard to their influence on antitumor immunity. Thus, for future combinatory approaches and particularly stop studies in CML treatment, choice of the most suitable BCR-ABL inhibitor requires careful consideration.

Dermoscopy and Overdiagnosis of Melanoma In Situ

In this issue of JAMA Dermatology, Lallas et al state that "our goal today is to detect melanoma, if possible, before it becomes invasive." Given the challenges related to the early detection of melanoma faced by clinicians and patients alike, this goal can only be achieved through further improving clinical training of clinicians, allied health care workers, and consumers alike, combined with heightened individual awareness and advanced imaging technologies.

Comorbidities in Autoimmune Skin Diseases

Alvan Feinstein, both a clinician and an epidemiologist, introduced the concept of comorbidity as a peculiar and important feature of chronic diseases almost 50 years ago. This concept may still require a more precise definition and a deeper understanding, but there is no doubt that better knowledge about comorbidities will always be conducive to improvements in clinical care, epidemiology, and health services planning and financing. Also, as noted by Tinetti and Fried nearly 15 years ago, awareness of existing comorbidities of a given chronic disease will facilitate "The End of the Disease Era," as they titled their article, and ultimately bring about the essential paradigm shift in clinical medicine from the "disease-oriented" model to a more "integrated individually tailored model" in which clinical decision making can be "focused primarily on the priorities and preferences of individual patients,"^(p181) and health conditions are recognized as a complex interplay of genetic, environmental, psychological, social, and other factors.

BackgroundChronic sinusitis is a commonly diagnosed condition in adults who frequently present with late-stage disease and irreversible changes to the sinus mucosa. Understanding the natural history of chronic sinusitis is critical in developing therapies designed to prevent or slow the progression of disease.ObjectiveWe sought to determine early life risk factors for adult sinusitis in a longitudinal cohort study (Tucson Children's Respiratory Study).MethodsPhysician-diagnosed sinusitis was reported at age 6. Adult sinusitis between 22 and 32 years was defined as self-reported sinusitis plus physician-ordered sinus radiologic films. Atopy was assessed by skin prick test. Individuals were grouped into 4 phenotypes: no sinusitis (n = 621), transient childhood sinusitis only (n = 57), late-onset adult sinusitis only (n = 68), and early onset chronic sinusitis (childhood and adult sinusitis, n = 26).ResultsSinusitis was present in 10.8% of children and 12.2% of adults. Childhood sinusitis was the strongest independent risk factor for adult sinusitis (odds ratio = 4.2; 95% CI: 2.5-7.1; P < .0001; n = 772). Early onset chronic sinusitis was associated with increased serum IgE levels as early as at 9 months of age, atopy (assessed by skin prick test reactivity), childhood eczema and allergic rhinitis, frequent childhood colds, maternal asthma, and with increased prevalence of concurrent asthma. No association was found between late-onset adult sinusitis and any of the early life risk factors studied.ConclusionsWe identified an early onset chronic sinusitis phenotype associated with a predisposition to viral infections/colds in early life, allergies, and asthma. Elucidation of the molecular mechanisms for this phenotype may lead to future therapies to prevent the progression of the disease into adult sinusitis.

BackgroundExposure to dietary constituents through the mucosal surface of the gastrointestinal tract generates oral tolerance that prevents deleterious T cell–mediated immunity. Although oral tolerance is an active process that involves emergence of CD4⁺ forkhead box p3 (Foxp3)⁺ regulatory T (Treg) cells in gut-associated lymphoid tissues (GALTs) for suppression of effector T (Teff) cells, how antigen-presenting cells initiate this process remains unclear.ObjectiveWe sought to determine the role of plasmacytoid dendritic cells (pDCs), which are known as unconventional antigen-presenting cells, in establishment of oral tolerance.MethodsGALT-associated pDCs in wild-type mice were examined for their ability to induce differentiation of CD4⁺ Teff cells and CD4⁺Foxp3⁺ Treg cells in vitro. Wild-type and pDC-ablated mice were fed oral antigen to compare their intestinal generation of CD4⁺Foxp3⁺ Treg cells and induction of oral tolerance to protect against Teff cell–mediated allergic inflammation.ResultsGALT-associated pDCs preferentially generate CD4⁺Foxp3⁺ Treg cells rather than CD4⁺ Teff cells, and such generation requires an autocrine loop of TGF-β for its robust production. A deficiency of pDCs abrogates antigen-specific de novo generation of CD4⁺Foxp3⁺ Treg cells occurring in GALT after antigenic feeding. Furthermore, the absence of pDCs impairs development of oral tolerance, which ameliorates the progression of delayed-type hypersensitivity and systemic anaphylaxis, as well as allergic asthma, accompanied by an enhanced antigen-specific CD4⁺ Teff cell response and antibody production.ConclusionpDCs are required for establishing oral tolerance to prevent undesirable allergic responses, and they might serve a key role in maintaining gastrointestinal immune homeostasis.

Author(s): Yeon Duk Woo, Jaemoon Koh, Hye-Ryun Kang, Hye Young Kim, Doo Hyun Chung
BackgroundThe XCL1–XCR1 axis has been reported to play a role in immune homeostasis and inflammation. However, it is not known whether this axis has a critical function in allergic asthma.ObjectiveIn the present study, we explored that the iNKT cell-mediated XCL1–XCR1 axis regulated the allergic asthma.MethodsOvalbumin (OVA) or house dust mite (HDM)-induced asthma was developed in XCL1 or XCR1 knockout (KO) mice.ResultsXCL1 or XCR1 KO mice showed attenuation in airway hyperresponsiveness (AHR), numbers of CD103⁺ dendritic cells (DCs), and Th2 responses in the lungs compared with wild-type (WT) mice during OVA or HDM-induced asthma. These effects were reversed by intratracheal administration of recombinant XCL1 or adoptive transfer of CD103⁺ DCs, but not CD11b⁺ DCs into XCL1 KO mice. Moreover, iNKT cells highly expressed XCL1 in vitro and in vivo. Upon intranasal α-galactosyl ceramide challenge, CD103⁺ DC numbers in the lungs were increased in WT, but not XCL1 KO mice. Furthermore, adoptive transfer of WT iNKT cells increased AHR, CD103⁺ DC recruitment, and Th2 responses in the lungs of CD1d KO mice during OVA-induced asthma, whereas that of XCL1-deficient iNKT cells did not. In human, the percentages and XCL1 production capacity of iNKT cells from peripheral blood mononuclear cells were higher in patients with asthma than healthy control.ConclusionThese data demonstrate that the iNKT cell-mediated XCL1–XCR1 axis promotes AHR by recruiting CD103⁺ DCs into the lung in allergic asthma.

Interleukins and their signaling pathways in the Reactome biological pathway database

Author(s): Steve Jupe, Keith Ray, Corina Duenas Roca, Thawfeek Varusai, Veronica Shamovsky, Lincoln Stein, Peter D'Eustachio, Henning Hermjakob
BackgroundThere is a wealth of biological pathway information available in the scientific literature, but it is spread across many thousands of publications. Alongside publications that contain definitive experimental discoveries are many others that have been dismissed as spurious, found to be irreproducible, or are contradicted by later results and consequently now considered controversial. Many descriptions and images of pathways are incomplete stylized representations that assume the reader is an expert and familiar with the established details of the process, which are consequently not fully explained. Pathway representations in publications frequently do not represent a complete, detailed, and unambiguous description of the molecules involved; their precise posttranslational state; or a full account of the molecular events they undergo while participating in a process. Although this might be sufficient to be interpreted by an expert reader, the lack of detail makes such pathways less useful and difficult to understand for anyone unfamiliar with the area and of limited use as the basis for computational models.ObjectiveReactome was established as a freely accessible knowledge base of human biological pathways. It is manually populated with interconnected molecular events that fully detail the molecular participants linked to published experimental data and background material by using a formal and open data structure that facilitates computational reuse. These data are accessible on a Web site in the form of pathway diagrams that have descriptive summaries and annotations and as downloadable data sets in several formats that can be reused with other computational tools. The entire database and all supporting software can be downloaded and reused under a Creative Commons license.MethodsPathways are authored by expert biologists who work with Reactome curators and editorial staff to represent the consensus in the field. Pathways are represented as interactive diagrams that include as much molecular detail as possible and are linked to literature citations that contain supporting experimental details. All newly created events undergo a peer-review process before they are added to the database and made available on the associated Web site. New content is added quarterly.ResultsThe 63rd release of Reactome in December 2017 contains 10,996 human proteins participating in 11,426 events in 2,179 pathways. In addition, analytic tools allow data set submission for the identification and visualization of pathway enrichment and representation of expression profiles as an overlay on Reactome pathways. Protein-protein and compound-protein interactions from several sources, including custom user data sets, can be added to extend pathways. Pathway diagrams and analytic result displays can be downloaded as editable images, human-readable reports, and files in several standard formats that are suitable for computational reuse. Reactome content is available programmatically through a REpresentational State Transfer (REST)-based content service and as a Neo4J graph database. Signaling pathways for IL-1 to IL-38 are hierarchically classified within the pathway "signaling by interleukins." The classification used is largely derived from Akdis et al.ConclusionThe addition to Reactome of a complete set of the known human interleukins, their receptors, and established signaling pathways linked to annotations of relevant aspects of immune function provides a significant computationally accessible resource of information about this important family. This information can be extended easily as new discoveries become accepted as the consensus in the field. A key aim for the future is to increase coverage of gene expression changes induced by interleukin signaling.

Bartter Syndrome Type 1 Presenting as Nephrogenic Diabetes Insipidus

Bartter syndrome (BS) type 1 (OMIM #601678) is a hereditary salt-losing renal tubular disorder characterized by hypokalemic metabolic alkalosis, hypercalciuria, nephrocalcinosis, polyuria, recurrent vomiting, and growth retardation. It is caused by loss-of-function mutations of the SLC12A1 gene, encoding the furosemide-sensitive Na-K-Cl cotransporter. Recently, a phenotypic variability has been observed in patients with genetically determined BS, including absence of nephrocalcinosis, hypokalemia, and/or metabolic alkalosis in the first year of life as well as persistent metabolic acidosis mimicking distal renal tubular acidosis. We report the case of a child with a genetically determined diagnosis of Bartter syndrome type 1 who presented with a phenotype of nephrogenic diabetes insipidus, with severe hypernatremia and urinary concentrating defect. In these atypical cases, molecular analysis is mandatory to define the diagnosis, in order to establish the correct clinical and therapeutic management.

Bronchogenic Cyst as an Unusual Cause of a Persistent Cough and Wheeze in Children: A Case Report and Literature Review

Wheezing and cough are common case scenarios that pediatricians encountered in their office practices. Although a bronchogenic cyst is an uncommon condition, it is essential to be considered in the differential diagnosis of a chronic cough and wheezing among young children who fail to respond to appropriate medical treatment. A 28-month-old girl was referred to our pediatric pulmonology clinic with persistent symptoms of a cough and wheeze unresponsive to standard asthma therapy. This presentation prompted us to undertake a detailed diagnostic evaluation. The evaluation exposed a cystic mass in the middle mediastinum compressing the trachea and left main bronchus. The cyst was excised and confirmed pathologically to be a benign bronchogenic cyst. Subsequently, the patient recovered well and had been free of respiratory symptoms during follow-up visits. This report highlights one of the rare causes of wheezing and cough in young children and emphasizes the importance of considering it in the differential diagnosis of a child presenting with refractory asthma-like symptoms. This is important for early diagnosis and management and to avoid unpredictable complications of this treatable condition.

PurposeTo evaluate different therapeutic Carnoy's solution formulations on hard human tissues.Materials and MethodsAn in vitro study was performed with human teeth (n=36) and bone fragments (n=18), randomly divided into two experimental groups (Group I = Carnoy solution with chloroform; Group II = Carnoy solution without chloroform) and a control group (saline solution). The groups were subdivided into pre-conditioning, post-conditioning, and post-conditioning with saline washing. Raman microspectroscopy, Knoop microhardness test, and scanning electron microscopy with energy dispersive X-ray spectroscopy were used.ResultsThere was demineralization of dental structures regarding mineral/matrix and carbonate/phosphate ratios (GI versus GII, p < 0.05). The presence of chloroform resulted in a statistically significant reduction of the teeth surface microhardness (p = 0.036), but not exceeding 0.01 μm. Both GI and GII showed significant structural changes by using scanning electron microscopy with energy dispersive X-ray spectroscopy.ConclusionCarnoy's solution altered the organic and inorganic matrix of the human calcified specimens analyzed in vitro, and its effect was more pronounced when chloroform was present.

Searches were performed on three databases and registered in the PROSPERO. The selected studies fulfilled the criteria established by the following PICO model: (1) population: individuals with skeletal dentofacial deformities (class II or III facial patterns), without asymmetry; (2) intervention: orthognathic surgery for mandibular setback using an SSRO, with or without a Le Fort I osteotomy, and fixed with bicortical screws or plates and screws; (3) comparison: orthognathic surgery for mandibular advancement using an SSRO, with or without a Le Fort I osteotomy, and fixed with plates and screws or bicortical screws; and (4) outcome: condylar resorption rate and relapse. Initially, 1,371 articles were identified and 636 articles were screened after elimination of duplicates, and 6 articles were selected for qualitative analysis based on the inclusion and exclusion criteria. Five studies had data regarding the rate of condylar resorption, varying from 0.0% to 4.2%. In conclusion, condylar resorption and relapses were present in a small percentage of patients studied.

IntroductionMaxillofacial injuries may result in psychological derangement of an individual, leading to post-traumatic stress disorder (PTSD) which is characterized by continual re-experiencing of any traumatic event along with numerous systemic complications.ObjectivesTo assess the incidence & severity of "PTSD related depression" in patients with maxillofacial injuries and to identify the risk factors involved.Methodology: The prospective study involved 88 patients with maxillofacial trauma who were grouped into (A) - Patients with cosmetic deficit alone, (B)- Patients with functional deficit alone and (C)- Patients with both cosmetic and functional deficit.The psychological status of all patients was assessed before & after surgery, using the Zung's Self rating Depression Scale. The remission time was also analysed.Statistical analysisData was analysed with SPSS, using parametric methods. Comparison of mean values between groups was done using one way ANOVA followed by Tukey's HSD post hoc tests for multiple pairwise comparisons. To compare proportions, Chi-Square test was applied.ResultsThe number of patients in Group A, B & C was 11, 34 and 43, respectively. In the immediate post- trauma stage, all patients in group A showed severe depression, while the percentage of patients with severe depression in group B and C were 8.8 and 81.4%, respectively, which was statistically significant. The depression scores in patients of all groups decreased gradually in the post- surgical phase. Patients with cosmetic defects consistently show relatively higher depression scores, at all time- intervals. The time taken for recovery from depression (Remission time) was lesser in patients with functional deficit alone (Group B).ConclusionPatients with maxillofacial injuries are prone to "PTSD related depression" due to both functional and cosmetic deficits. The objectives of trauma management must be aimed at restoring pre-trauma form & function of maxillofacial skeleton as well as patient's psychological status.

Treatment of pseudoaneurysms in the internal carotid artery (ICA) is associated with a high risk of cerebral infarction; therefore, vessel ligation for hemostasis must be avoided. A 66-year-old man experienced intra-oral hemorrhaging. At the time of the initial examination, computed tomography angiography revealed jaw plate displacement near the ICA. A more detailed image was obtained using digital subtraction angiography. After evaluation of the image, a pseudoaneurysm was diagnosed. Six days later, there were concerns about aspiration and airway obstruction; therefore, tracheostomy was performed. Interventional vascular radiology and surgery were planned to facilitate complete recovery, removal of the jaw plate, and repair of the pseudoaneurysm. Before surgery, it was confirmed that it would be possible to block blood flow for approximately 20 minutes. Surgery was performed under general anesthesia. Before plate removal, cardiovascular surgeons exposed the left large saphenous vein and prepared it so that it could be used to patch the vascular wall defect. An embolic protection device (EPD) was placed so that it could be inflated at any time after plate removal via oral surgery. The pseudoaneurysm was found directly under the plate; however, it had adhered to the scar tissue. As removal progressed, hemorrhaging occurred. To achieve hemostasis, the EPD balloon was inflated. The pseudoaneurysm was removed and a red thrombus was aspirated. On postoperative day 41, bleeding reoccurred. Two days later, embolization using a platinum coil and stent placement were performed through interventional vascular radiology (IVR) monotherapy. Postoperative progress was favorable and the patient was discharged 83 days after treatment without neurologic sequelae. ICA pseudoaneurysms located near the skull base are risky and challenging to repair. However, for traumatic aneurysms such as this one, a combination of IVR therapy and surgery is useful for controlling intraoperative hemorrhage.

PurposeThe aim of the present study was to compare the long-term stability of bimaxillary surgery using an intraoral vertical ramus osteotomy (IVRO) with and without pre-surgical orthodontic treatment.MethodsThe present retrospective study included 31 consecutive patients with skeletal Class III malocclusions who had undergone bimaxillary surgery (Le Fort I osteotomy and bilateral IVRO). Patients were divided into two groups based on treatment type: pre-orthodontic orthognathic surgery (POGS, n=17) and conventional surgery (CS, n=14) with pre-surgical orthodontic treatment. Lateral cephalograms were obtained before surgery, 1 day after surgery, 1 month after surgery, 1 year after surgery, and 2 years after surgery to evaluate skeletal and soft tissue changes between the two groups. The data were analyzed using chi-square tests, Mann-Whitney U tests, repeated-measures analyses of variance and independent t-tests.ResultsThere was no significant difference in skeletal or soft tissue measurements—with the exception of the angle between the sella-naison plane and the occlusal plane (SN-OP) (P < 0.001)— between the CS and POGS groups at 2 years after IVRO. The SN-OP had increased in the CS group but decreased in the POGS group at 2 years after surgery.ConclusionsOur findings suggest that POGS and CS are associated with similar long-term stability in patients with skeletal Class III malocclusion.

The prevalence, nature, and management of oral stage dysphagia in adults with temporomandibular joint disorders: Findings from an Irish cohort

Publication date: Available online 20 February 2018
Source:Journal of Oral and Maxillofacial Surgery
Author(s): Órla Gilheaney, Leo FA. Stassen, Margaret Walshe
PurposeTemporomandibular disorders (TMDs) are caused by changes in the structure and/or function of the temporomandibular joint, masticatory muscles, and/or osseous components. TMDs may result in oral stage dysphagia (OD) with potential effects on function and patient well-being. Little is known about the prevalence, nature, and management of TMD-related OD. The aims of this study were to estimate the prevalence and nature of OD in adult TMD patients, and to identify common management techniques used to manage the signs and symptoms of TMD-related OD.MethodsAn 18-item subjective questionnaire was adapted from existing tools and used to investigate TMD aetiology, symptoms, and signs of TMD-related OD, and intervention techniques employed to manage these symptoms. This was disseminated to 178 TMD patients consecutively recruited over 6-months in 2016. Descriptive and statistical methods were used to analyse the data.ResultsNinety nine percent of TMD participants reported at least one symptom/sign of OD. Individuals presenting with subluxation of the jaw (80%), degenerative joint disorder (67%), and myofascial pain disorder (40%) reported OD most frequently. Common symptoms included painful mastication (90%), masticatory fatigue (78%), difficulties swallowing (33%), and difficulties drinking liquids (28%). Use of a broad range of management techniques was reported, with these including both OD-specific (e.g.: diet modifications (81%)), and non-OD specific techniques (e.g: analgesia (79%) and oral splints (75%)).ConclusionOD is prevalent and difficulties with mastication are common in TMDs. Interventions employed were diverse, with varying objectives and disparate levels of evidence supporting their efficacy within this cohort. Further research should address the epidemiology of TMD-related OD, evidence-based interventions, and the promotion of collaboration across disciplines responsible for managing TMD-related OD (e.g.: speech and language therapy, oral and maxillofacial surgery, dentistry, restorative dentistry, orthodontics, oral medicine etc.).

PurposeDesktop stereolithographic printers, in combination with intraoral scanning and implant planning software, promise precise and cost-effective guided implant surgery. The purpose of this study was to determine the overall range of accuracy of tooth-supported guided implant surgery using desktop printed stereolithographic guides.Materials and MethodsA cross-sectional study comparing fully and partially guided implant surgery was conducted. Preoperative cone-beam computed tomography (CBCT) and intraoral scans were used to plan the implant sites. Surgical guides were then fabricated using a desktop stereolithographic 3D printer. Postoperative CBCT was used to evaluate the accuracy of placement. The deviations from planned positions were used as the primary outcome variables. The planning software used, implant systems, and anterior/posterior positions were secondary outcome variables. The differences between the planned and actual implant positions in the mesial, distal, buccal, lingual dimensions, and the bucco-lingual angulations, were determined and the accuracy was compared statistically using one-tail F-test (p=0.01), box plots and 95% confidence interval for means.ResultsSixteen partially edentulous patients requiring placement of 31 implants were included in the study. The implant deviations from the planned positions with the fully guided protocol (n=20) were 0.17+/-0.78mm, 0.44+/-0.78mm, 0.23+/-1.08mm, -0.22+/-1.44mm and -0.32+/-2.36°, respectively. The implant deviations for the partially guided protocol (n=11) were 0.33+/-1.38mm, -0.03+/-1.59mm, 0.62+/-1.15mm, -0.27+/-1.61mm, and 0.59+/-6.83°, respectively. There was a statistically significant difference between the variances of fully and partially guided surgery for the distal and angulation dimension (p=0.006, and p<0.001). There was no statistical difference between software programs. Anterior implants had less variation in deviation than posterior implants.ConclusionsFully guided implant surgery is more accurate then partially guided implant surgery. Implant positional deviation is influenced by implant location, but not implant systems or software. If possible clinicians should use guided surgery protocols that allow placement of implants through a surgical guide.

Author(s): Tiago Gai Aita, Cecília Luiz Pereira Stabile, Cássia Cilene Dezan Garbelini, Glaykon Alex Vitti Stabile
PurposeTo evaluate whether the Facial Injury Severity Scale (FISS), proposed by Bagheri et al. in 2006, can predict intervention needs in an operating room (OR), length of hospital stay, and the need for support by other specialties.Patients and MethodsData were collected from the medical records of trauma patients from a public tertiary hospital between January 2009 and December 2015, related to age, gender, comorbidities, habits, history of maxillofacial trauma, etiology, and the presence and location of fractures and lacerations, in addition to the type of treatment performed and period of hospitalization. A score was applied to each patient according to the FISS. Multinominal logistic regression models were adjusted and all analyzes were performed using the IBM statistical package "Statistical Package for Social Science" (SPSS), version 17.0.ResultsThe final sample consisted of 469 medical records. Mean age was 31.38 ± 14.13 years. Traffic accidents were the most frequent cause (41.2%) followed by interpersonal violence (29.4%). The most commonly fractured bone was the mandible (32.9%), and the mandibular angle was the most affected region (29.0%). Reports of alcohol intake resulted in a 100% increase in the need for treatment of fractures in an OR. Patients with FISS> 5 presented 18 times the chance of needing intervention in an OR, and a greater possibility of hospitalization longer than 3 days (< 0.01). The mean length of hospital stay was 8.14 days ± 6.02, with a statistically significant longer hospitalization period for smokers (p <0.0001). Patients with any type of comorbidity were more likely to require support from other specialties (p = 0.022), and those with FISS> 5 were 6.6 times more likely to need this support (p <0.0001).ConclusionHigher FISS values may predispose patients to a longer hospitalization time, greater chances of being submitted to surgical procedures, and the need for follow-up by other medical specialties.

The CCL5/CCR5 Chemotactic Pathway Promotes Perineural Invasion in Salivary Adenoid Cystic Carcinoma

Publication date: Available online 20 February 2018

PurposePerineural invasion (PNI) is a hallmark of salivary adenoid cystic carcinoma (SACC) and represents an important risk factor for local recurrence and poor survival. However, the mechanism of PNI has yet to be explored. In this study, we sought to examine the CCL5-CCR5 ligand-receptor interaction between nerves and salivary adenoid cystic carcinoma cells.Materials and methodsCCL5/CCR5 expression was determined by immunohistochemistry in SACC tissue specimens. Correlations between CCL5/CCR5 expression and clinicopathologic features were investigated. Dorsal root ganglia (DRG) and SACC cells cocultured in vitro were used to evaluate the effects of CCL5/CCR5 on PNI progression and pathogenesis.ResultsCCR5 expression was significantly elevated in SACC tissues and associated with distant metastasis, perineural invasion, and TNM grade (P<0.05). Dorsal root ganglia (DRG) and SACC cells cocultured in vitro showed that the activation of the CCL5/CCR5 axis significantly increased SACC cells invasion and promoted the outgrowth of the DRG. SACC cell lines expressing CCR5 migrated in response to CCL5 derived from DRG, eventually leading to PNI. Most importantly, further study showed that blocking of CCL5 or CCR5 effectively inhibited the invasive capacity and PNI activity of SACC cells (P<0.05).ConclusionsOur study suggests a pivotal role of CCL5/CCR5 axis in tumor-nerve interactions during PNI of SACC. The CCL5/CCR5 pathway may prove to be an attractive new target for the treatment of SACC with PNI.

Landmark-independent method to determine mid-sagittal plane (MSP) and its clinical application in craniomaxillofacial trauma

Publication date: Available online 20 February 2018
Source:Journal of Oral and Maxillofacial Surgery
Author(s): Xiaotian Lian, Jun Guo, Wei Zeng, Hai Qing, Rui Ju, Wei Tang
PurposeThe purpose of this study was to explore new landmark-independent methods suitable for determining the mid-sagittal plane (MSP) in patients with craniomaxillofacial trauma and its clinical application.MethodsPreoperative CT data of 25 patients with craniomaxillofacial trauma was imported into Mimics software to reconstruct three-dimensional (3D) skull model. In experimental group, MSP was determined by different landmarks that are clear, scattered and do not have displacement according to the types of the fracture. In the control group, MSP was determined by traditional landmark-dependent method based on Nasion (Na), posterior nasal spine (PNS) and anterior nasal spine (ANS). After virtual fracture reduction, facial symmetry was determined to verify the reliability of both landmark-dependent and landmark-independent methods.ResultsUsing landmark-independent method proposed in this study, the minimal, maximal and average registered distance between the skull model after reduction and the mirror skull model was 0.5531, 1.2065, and 0.8287mm, respectively. Using the traditional landmark-dependent method, the minimal, maximal and average registered distance between the skull model after reduction and the mirror skull model was 0.7914, 1.9415, and 1.2250mm, respectively. When the average distance of <1.5mm between the two registered models was set as the criteria for qualified fracture reduction, all the 25 cases in the experimental group had qualified reduction, while 9 cases in the control group had unqualified reduction (P<0.05).ConclusionCompared to traditional landmark-dependent system, landmark-independent method is more reliable in determining MSP in patients with craniomaxillofacial trauma. Selection of different landmarks in different types of fractures makes it more precise to reconstruct MSP and can guide virtual reduction of fracture more effectively, which lays the foundation for subsequent surgical navigation and guide plate printing. The method is easy to operate and appropriate for digital evaluation of surgery.

Author(s): Jun Li, Yi Shen, Liang Wang, Jin-bing Wang, Jian Sun, Thorsen W. Haugen
PurposeTo review our surgical experience in maxillary and midface reconstruction using free vascularized tissue, and to compare the postoperative outcomes based on superficial temporal versus cervical recipient vessels.MethodsA retrospective review was performed on patients who underwent maxillary and midface reconstruction with free vascularized tissue from March of 2001 to July of 2014. Two groups were analyzed: those in which the superficial temporal vessels were used as recipient vessels and those in which cervical vessels were used as the recipient vessels. Patient gender, age, cause and classification of the defect, flap choice for reconstruction, recipient vessels, postoperative course and complications were additionally recorded and analyzed. A two-tailed Fisher exact test was used to compare outcomes between the two groups.ResultsBased on the different recipient vessels, 94 patients were divided into two groups: those with superficial temporal recipient vessels (n = 44), and those with cervical recipient vessels (n = 50). The overall flap survival rate was 99.0%. The overall complication rate for vascular anastomoses was 5.3%. The complication rate for those with cervical recipient vessels was higher than the complication rate for those with superficial temporal recipient vessels (8.0 vs 2.27%, p = 0.37). Additionally, for those in the group with superficial temporal recipient vessels, the postoperative scar in the pre-tragal region was rated as more satisfactory than the post-surgical scars for those in the cervical recipient vessel group.ConclusionThe authors recommend that the superficial temporal vessels be the first option for recipient vessels in free vascularized tissue maxillary and midface reconstruction due to proximity; superficial positioning; suitability for anastomosis and monitoring; and because these vessels are rarely compromised by prior operations or radiotherapy.

AimTo test a hypothesized positive association between low Vitamin D (VitD) serum levels and the severity of periodontal disease in HIV-infected women.Materials and MethodsThis is a cross sectional secondary analysis of data from an oral substudy conducted within the Chicago site of the Women's Interagency HIV Study. Serum VitD levels and clinical attachment loss measurements were available for 74 HIV-infected women. VitD levels were treated as both continuous and categorical variables in bivariate and multivariate analyses. Mean clinical attachment loss (mCAL) was determined for each subject by averaging measurements taken at 4 sites in each measured tooth.ResultsAverage age of study participants (n=74) was 39.6 years (SD 7.2) and the majority were African-American (70.3%) and VitD deficient (58.1%). VitD deficiency was positively associated with higher mCAL (p=.012). With adjustment for race, age, smoking, HIV viral load, an association was found between VitD deficiency and mCAL (Beta 0.438, p=0.036).ConclusionsWe identified a previously unreported association between VitD deficiency and mCAL in HIV-infected women. Larger and more inclusive multisite longitudinal studies are warranted to investigate whether these findings generalize to all HIV infected individuals in the current treatment era and to determine causality.

Gastric and duodenal ischaemia after transarterial chemoembolisation for hepatocellular carcinoma: an unexpected but significant complication

Transarterial chemoembolisation (TACE) is commonly used for unresectable intermediate-stage hepatocellular carcinoma (HCC). TACE is usually well-tolerated. We report a case of a patient who presented with a gastrointestinal bleed from TACE. A 64-year-old man presented with chronic hepatitis C cirrhosis and multifocal bilobar HCC. He had previously undergone multiple TACE sessions, radiofrequency ablation and stereotactic body radiation therapy. In the evening of his TACE procedure, he developed abdominal pain and haematemesis. An oesophagogastroduodenoscopy (OGD) showed non-bleeding oesophageal varices and ulcerations in the stomach and duodenum, with pathology demonstrating mucosal necrosis. The patient recovered and was discharged on omeprazole. While TACE is considered safe with most patients only experiencing postembolisation syndrome, vascular complications have been reported. In our patient, OGD revealed ulcerations, with biopsies confirming ischaemic ulceration. The likely aetiology was seepage of the embolic particles into neighbouring arteries. Patients should be carefully selected for TACE and monitored post procedure.

Systemic lupus erythematosus presenting to haematology with pancytopenia and features of macrophage activation syndrome

Description 

This bone marrow biopsy (figure 1) shows haemophagocytosis consistent with macrophage activation syndrome (MAS) secondary to previously undiagnosed systemic lupus erythematosus (SLE).

Figure 1

Bone marrow biopsy with abundant cell-bound haemosiderin and focal haemophagocytosis with cellular debris identified in macrophage cytoplasm (arrows). This is consistent with, but not specific for, macrophage activation syndrome.

A 44-year-old woman had been unwell for 4 weeks with fever, weight loss and an aphthous ulcer. There were no other clinical features of SLE.

There was pancytopenia (platelet count 65x10⁹/L; neutrophil count 0.5x10⁹/ L; haemoglobin 107 g/L). The reticulocyte count was 20x10⁹/ L. Parvovirus and Epstein-Barr virus IgM were not detected.

A very high ferritin level of 3717 µg/L in the context of cytopenias was suggestive of MAS, a life-threatening hyperinflammatory state.1 Clinical features of MAS include fever, lymphadenopathy and hepatosplenomegaly. Laboratory markers include pancytopenia, altered liver function...

Successful perioperative management in a patient with factor XI deficiency

Factor XI (FXI) deficiency is an autosomal disorder which manifests as bleeding of varying severity. While homozygotes typically experience more dramatic bleeding symptoms, heterozygotes may experience clinically significant bleeding following surgical procedures or trauma, and therefore the condition is not purely recessive. The clinical significance of FXI deficiency is complicated in that FXI levels do not correlate well with bleeding severity, and in fact the bleeding risk is variable even for an individual in response to different haemostatic challenges. We present the case of a 74-year-old man of Ashkenazi Jewish heritage with a family and personal history of bleeding during surgical procedures, who presented with excessive bleeding following total thyroidectomy. He was found to have a FXI level of 52% (low normal). Genetic testing revealed that he was heterozygous for the c.403G>T mutation. This case demonstrates successful work-up and perioperative management of a patient with FXI deficiency.

Cefepime-induced encephalopathy

Description

A 61-year-old man has been unable to leave his bed since being diagnosed with cerebral palsy at the age of 2 years. He is fed via a gastrostoma and has previously contracted aspiration pneumonitis three times. He has had no history of seizures or myoclonic movements until the time of hospitalisation. He visited a physician with complaints of fever lasting for 1 week and a cough that had been increasing in severity. He was diagnosed with pneumonia and treated with 100 mg oral cefcapene three times a day. As his condition did not improve, he was referred to our hospital for treatment. A chest X-ray and CT scan revealed abscess formation in the right middle lobe of the lung, and he was diagnosed with pulmonary suppuration. Initially, he was given 2 g of ceftriaxone every 24 hours. Following detection of Pseudomonas aeruginosa in the sputum culture, we discontinued ceftriaxone and initiated...

It Is Not Always Sepsis: Fatal Tachypnea in a Newborn

Coarctation of the aorta (CoA) is a congenital cardiac malformation that is well understood. Despite being well characterized, CoA is a commonly missed congenital heart disease (CHD) during the newborn period. We report a full-term nine-day-old male who presented to the pediatric emergency department (ED) with isolated tachypnea. After an initial sepsis workup, subsequent investigations revealed critical CoA. Because the primary workup focused on sepsis, there was a significant delay in prostaglandin E1 (PGE1) initiation. This case illustrates the importance of early CoA recognition and timely initiation of PGE1 in newborns who present with suspected sepsis along with tachypnea.

Gastrointestinal stromal tumour as a rare association with neurofibromatosis type 1

Abstract

Gastrointestinal stromal tumours (GIST) are rare tumours of mesenchymal origin. These can be associated with neurofibromatosis type 1 (NF1), which is an autosomal dominant disorder. The prevalence of GIST in NF1 is estimated at 3.9–25%. This paper describes the presentation of a GIST arising from the jejenum in a 75-year-old lady with NF1, who presented with gastrointestinal bleeding. This was diagnosed by CT angiography. She was managed with laparotomy, with resection of small bowel, and an ischaemic segment of large bowel with two primary anastomoses. Pathology showed GIST of spindle cell type (Figs 3 and 4), 90 mm in size, with complete local excision. The patient was discharged on the eighth post-operative day and is currently undergoing regular clinic follow-up after multidisciplinary team meeting discussion.

Robot-assisted repair of diaphragmatic hernias following ventricular assist device implantation

Abstract

Use of ventricular assist devices (VADs) is increasingly common, as is the need for surgeons to be familiar with the management of common complications in this population. Nonetheless, repair of diaphragmatic hernias which commonly develop following VAD implantation remains technically challenging due to intra-abdominal adhesions and the proximity of vital structures. Despite the potential benefits of improved dexterity and visualization, robotic approaches have thus far not been used to address this. We present the first two described cases of robot-assisted repair of diaphragmatic hernias in the setting of prior or current VAD placement.
