Prevalence of the systemic inflammatory response syndrome in patients who underwent orthognathic surgery

Abstract

Purpose

The systemic inflammatory response syndrome (SIRS) is the body's response to an insult, such as infection, trauma, burn, and surgical stress linked to several factors deemed potential for multiple organ failure if left untreated. Thus, the aim of this paper was a prospective study to examine the incidence of SIRS in postoperative patients who underwent orthognathic surgery from June/2013 to July/2016.

Methods

The sample consisted of 80 patients who underwent bimaxillary orthognathic surgery, with data on vital signs and white blood cell count collected preoperatively, and the same data collected in the immediate postoperative period, in addition to CO2 pressure in arterial blood by blood gas analysis. The data were tabulated and cases of SIRS (2 or more signs out of four pre-set signs) were identified within 24 h after surgery.

Results

From the sample of 80 patients, 26 (32.5% of total) patients had SIRS with higher incidence in females who are 40 years old.

Conclusion

The incidence of patients who develop SIRS after orthognathic surgery is relatively high and we should pay attention to the possible complications that these cases can evolve.

Author(s): D.M. dos Santos, F.P. de Caxias, S.B. Bitencourt, K.H. Turcio, A.A. Pesqueira, M.C. Goiato
Patients who have maxillectomy can be rehabilitated with reconstructive surgery or obturator prostheses with or without osseointegratable implants. To identify studies on possible treatments in this group, we systematically searched the Scopus, Embase, PubMed/Medline, and Cochrane databases to collect data on patients' characteristics, radiotherapy, and results related to speech, swallowing, mastication or diet, chewing, aesthetics, and quality of life. Of the 1376 papers found, six were included, and one other was included after an additional search of references. A total of 252 patients were included, and of them, 86 had reconstructive surgery, 91 were treated with obturator prostheses, 39 had reconstructive surgery or obturator prostheses associated with implants, and 36 had reconstruction plus an obturator prosthesis. Data on radiotherapy were incomplete. There is a lack of consensus about the indication for rehabilitation, as the treatment must be based on the individual characteristics of each patient.

Various methods have been described to establish maxillomandibular fixation in the treatment of fractures of atrophic, edentulous mandibles. We used the Synthes MatrixWAVE™ system (DePuy Synthes) in combination with dentures in two patients with fractured, edentulous, atrophic mandibles. Fixation was maintained for fractures that were not amenable to, or did not require, open reduction and internal fixation, and the mandibles were both well-healed and had good function at the end of treatment.

Significance of Testing Anti-Thyroid Autoantibodies in Patients with Deranged Thyroid Profile

Background. We hypothesized that anti-thyroid antibodies are more often positive in individuals with deranged thyroid profile. Methods. This prospective cohort was done in Immunology Department, Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from Jan 2017 to Oct 2017. All the samples that were referred to us for testing anti-thyroid antibodies (anti-TPO or anti-TG antibodies) and thyroid profile were included in the study. There were no exclusion criteria. Tests for anti-thyroid antibodies were performed by ELISA and thyroid profile by chemiluminescence. SPSS 23.0 was used for statistical analysis. Results. Over a course of a ten-month study period, we received a total of 316 serum samples for anti-TPO/TG antibodies along with thyroid profile testing (TSH). These included 115 males (36.4%) and 201 females (63.6%). Their age ranged from 3 to 89 years (mean ± SD, 42.22 ± 18.09). Anti-TPO antibodies were more often positive when TSH was deranged ( value 0.001). Anti-TPO antibodies are more often raised in females, in terms of both prevalence ( 0.001) and mean rank ( 0.002). Conclusion. As anti-thyroid antibodies are more often present when TSH is deranged, such individuals should be screened for anti-thyroid antibodies. This importance of screening is compounded by the fact that anti-thyroid antibodies may be positive in a significant percentage of elderly people.

PurposeIn the first months of life, any deviation from a physiological growth pattern can cause skull deformity. As there has not been any longitudinal three-dimensional (3D) study investigating the physiological growth of the infant skull, the aim of the present study was to acquire such data.Materials and MethodsWe performed 3D stereophotogrammetric scans of 40 infants without cranial asymmetry at four regular 2-month intervals from the 4th to the 10th month of age. Six growth-related parameters (circumference, length, width, height, cranial index [CI; width-length ratio] and total head volume) were used to analyse skull growth longitudinally.ResultsWith exception of the CI, all parameters showed significant increases, with maximum percentage growth from the 4th to the 6th month. The CI initially remained unchanged until the 6th month, before showing a significant reduction that continued throughout the study period. Male infants had larger heads than female infants, but a similar width-length ratio at all measurement times.ConclusionThis prospective study is the first longitudinal 3D analysis to examine the physiological growth dynamics of infants' heads within the first months of life. Understanding patterns of skull growth in all three dimensions is important for gaining further insights into physiological and pathophysiological skull development.

A series of 240 odontogenic keratocysts: Should we continue to use the terminology of ‘keratocystic odontogenic tumor’ for the solid variant of odontogenic keratocyst?

Publication date: Available online 11 April 2018
Source:Journal of Cranio-Maxillofacial Surgery
Author(s): Devrim Kahraman, Omer Gunhan, Bulent Celasun
Most of the odontogenic keratocysts show an indolent behaviour like non-neoplastic lesions. For this reason, the odontogenic keratocyst was reclassified within the odontogenic cysts category in the WHO 2017 classification. Some odontogenic keratocysts may contain satellite cysts or solid squamoid islands within their wall. Recently, a solid form of odontogenic keratocyst has also been described which is composed entirely of multiple epithelial islands and small cysts in a collagenous stroma. The true nature of this variant is unclear yet.In this article, we present a series of 204 odontogenic keratocyst cases. Clinical and histologic findings of the cases in this series were described. These were also categorised according to the presence of satellite lesions. Additionally, the features of two cases of the solid form of odontogenic keratocysts were compared with those of the previous reports and other histologically similar odontogenic lesions. Current evidence suggests that this variant may be neoplastic and it differs from other odontogenic keratocysts, at least histologically. We believe diagnosing a solid lesion as a cyst is counterintuitive and the term "keratocystic odontogenic tumor" better describes this particular variant.

A three-dimensional (3D) X-ray tomogram evaluation gives a full view of the bone distribution around an entire implant in contrast to the often-used two-dimensional (2D) histological methods. High-resolution X-ray absorption tomography was used to evaluate the 3D bone growth around dental implants in an experimental goat mandible reconstruction model. The tomograms allowed for the construction of virtual histological cross-sections that could be used to evaluate the statistical uncertainty of the histological methods, which was the purpose of this paper. The virtual 2D histological results showed a significantly higher uncertainty within the same sample than did the full 3D volume results.

IntroductionThe full epidemiology and etiology of hemimandibular hyperplasia (HH) has not yet been clarified. In most cases it starts before puberty and results in various forms of dento-alveolar and skeletal discrepancies. This study is the first attempt at evaluating and describing some of the authors' key experiences, clinical philosophical approach, and gathered demographic data on hemimandibular hyperplasia and hemimandibular elongation (HE) among the Polish population.Material and methodA total of 45 patients (M=8; F=37; p<0.05) with HE (n=16; 35.6%; p<0.05), HH (n=28; 62.2%; p<0.05), or HH+HE (n=1; 2.2%; p>0.05) had been diagnosed and treated. Epidemiological, geographical, and clinical data concerning the occurrence and treatment protocols in these mandibular malformations were measured in the Polish study groups.ResultsWomen more often suffered from these mandibular malformations (82–87%). The occurrence of the first symptoms was highest at the age of 13–15 years and was statistically significant for both sides (p<0.05). The disorders were found earlier in young girls, therefore an early compensatory orthodontic treatment in some cases had been used with a limited degree of success (p>0.05). All values of bone scintigraphy were significant (p<0.001).ConclusionsA very fast growth with visible major asymmetry and enlarged condylar head should be an indication for condylectomy. Women's expectations from surgery and treatment are more demanding than men's, a fact that is connected with the predominance of females in the study group. Almost all possible treatment alternatives are not only related with the degree of skeletal deformity, but also with the patient's willingness to undergo any necessary treatment protocols, which in most cases involve more than one stage. Skeletal scintigraphy tests are an important factor in estimating bone growth and possible surgical approaches in these disorders.

Author(s): Khaled Dahy, Katsu Takahashi, Kazuyuki Saito, Honoka Kiso, Ibrahim Rezk, Toru Oga, Ryuji Uozumi, Kazuo Chin, Kazuhisa Bessho
PurposeThe aim of this study was to examine and compare morphological and functional outcomes after either isolated mandibular setback or bimaxillary surgery in males and females.Materials and MethodsA retrospective study was done on 52 patients, in whom surgical correction for mandibular prognathism was performed either by isolated mandibular setback (30 cases) or by bimaxillary surgery (22 cases). Morphological changes were studied using cephalograms and functional changes studied using impulse oscillometry (IOS) taken before surgery (T0), 3 months (T1) and 1 year after surgery (T2). Also 3% oxygen desaturation index (ODI) was measured at T0 and T2.ResultPosterior airway space decreased significantly in both groups and both sexes but more so in males after mandibular setback surgery and in females after bimaxillary surgery. Changes in supine R20 (central airway resistance at 20 Hz) and supine R5 (total airway resistance at 5 Hz) in IOS statistically significantly increased in the period T0–T1 in males compared with females after mandibular setback surgery (p < 0.05).ConclusionGender dimorphism is present according to morphological and functional outcomes, with males at a higher risk for obstructive sleep apnea (OSA) after mandibular setback surgery and females after bimaxillary surgery; howevert, compensatory changes act as a barrier against this.

Does lag screw fixation of condylar fractures result in adequate stability? A finite element analysis

Publication date: Available online 11 April 2018

The great incidence and controversies related to the diagnosis, treatment, surgical accesses, and type of osteosynthesis materials confer an outstanding role to condylar fractures among facial fractures. Plate configurations, with diverse formats and sizes, may be used to surgically resolve condylar fractures. With the purpose of improving the advantages and minimizing the disadvantages of fixation techniques, the neck screw was developed aiming at the needed stabilization to render a correct fixation through a system of dynamic compression. This is achieved by increasing the contact between the fractured bone stumps, as well as assisting at the time of fracture reduction. The present paper aims at comparing the fixation and stability of mandibular condylar fractures using the neck screw and an overlaid "L"-shaped-4-hole-2mm plate on the one hand, with a system in which the neck screw and the "L"-shaped plate form a single structure, having been joined by a welded point, on the other hand. The results with the neck screw are satisfactory, and, thus, it is an alternative for the reduction and fixation of fractures of the mandibular condyle, whether or not a plate is joined to the structure, provided it is correctly prescribed and with adequate surgical sequence and technique.

In vitro study of a modified sagittal split osteotomy fixation technique of the mandible: a mechanical test

This study was performed to evaluate the compressive mechanical strength of rigid internal fixation (RIF) using 1.5-mm L-shaped plates fixed with monocortical screws in sagittal split osteotomy (SSO). Thirty synthetic hemimandibles, which had all undergone a 5-mm advancement, were divided into three groups: three 12-mm bicortical titanium screws were placed in an inverted L pattern in group A; one straight 2.0-mm system spaced titanium plate fixed with four 5-mm monocortical screws was used in group B; two 1.5-mm system L-shaped titanium plates, each fixed with four 5-mm monocortical screws, were used in group C.

Risk factors and clinical outcomes of sinus membrane perforation during lateral window sinus lifting: analysis of 120 patients

The aim of this study was to identify the risk factors associated with sinus membrane perforation and the effect of sinus membrane perforation and other risk factors on graft success and postoperative sinusitis. Sinus membrane perforation, graft failure, and postoperative sinusitis were tested for an association with age, sex, operator experience, side of the operation, residual bone height, presence of septa, presence of a mucous retention cyst, and smoking (χ2 test). Logistic regression analysis was used to model the odds ratio (OR) with corresponding risk factors.

Author(s): M. Cassetta, F. Altieri, R. Di Giorgio, E. Barbato
The aim of this report was to describe a new computer-guided technique for a controlled site preparation and palatal orthodontic miniscrew insertion using a dedicated software. A surgical guide was designed after planning the appropriate insertion sites on three-dimensional images created by the fusion of cone-beam computed tomography (CBCT) and digital dental model images. Pre- and postoperative CBCT images were compared and the angular, coronal, and apical deviations between the planned and the placed miniscrews were calculated. The mean coronal and apical deviations were 1.38mm (range: 3.48–0.15mm; standard deviation (SD): 0.65) and 1.73mm (range: 5.41–0.10mm; SD: 1.03), respectively, while the mean angular deviation was 4.60° (range: 15.23–0.54°; SD: 2.54). The present surgical guide allows a controlled and accurate palatal miniscrew placement in three dimensions.

The aim of this study was to identify the risk factors associated with sinus membrane perforation and the effect of sinus membrane perforation and other risk factors on graft success and postoperative sinusitis. Sinus membrane perforation, graft failure, and postoperative sinusitis were tested for an association with age, sex, operator experience, side of the operation, residual bone height, presence of septa, presence of a mucous retention cyst, and smoking (χ2 test). Logistic regression analysis was used to model the odds ratio (OR) with corresponding risk factors. One hundred and twenty patients were included in this study. A total of 22 (18.3%) perforations occurred. A residual bone height of 3–6mm (OR 6.808, P=0.002) and presence of septa (OR 4.023, P=0.025) were identified as significant risk factors. Twenty-eight (23.3%) sinus grafts were classified as failed. Membrane perforation (OR 16.819, P<0.005) and residual bone height of 3–6mm (OR 5.363, P=0.01) were identified as significant risk factors for graft failure. None of the risk factors investigated in this study was significantly associated with postoperative sinusitis. These results suggest that the presence of septa and a residual bone height of 3–6mm are associated with an increased risk of sinus membrane perforation, and that sinus membrane perforation has a negative effect on graft success.

Clinicopathological investigation of odontogenic fibroma in tuberous sclerosis complex

Publication date: Available online 10 April 2018

Author(s): A. Musha, S. Yokoo, Y. Takayama, H. Sato
Tuberous sclerosis complex (TSC) is an autosomal dominant inherited disease characterized by systemic hamartoma and diverse systemic features. TSC1 and TSC2 are the causative genes, and mental retardation, epileptic seizures, and facial angiofibroma develop in many patients with the disease. The case of a patient with TSC who developed a central odontogenic fibroma of the mandible is reported here. The patient was a 21-year-old woman who was referred with a swelling of the labial gingiva in the region of the right lower lateral incisor and canine. Dental radiography revealed a multilocular radiolucent region with a clear boundary. The right lower lateral incisor and canine were continuous with the lesion and thus were excised en bloc. The lesion was encapsulated and easily dissected. The diagnosis on immunohistological staining was odontogenic fibroma without an epithelial component. TSC1/2 gene mutation causes abnormal activation of mammalian target of rapamycin (mTOR) downstream of the PI3K–AKT pathway. The odontogenic fibroma in this patient was positive for mTOR, suggesting that the development of the odontogenic fibroma was the result of abnormal activation of mTOR, as in angiofibroma. The clinical course of this patient is presented and the developmental mechanism of central odontogenic fibroma is discussed.

Odynophagia and neck pain after exercise

Description

A previously healthy, non-asthmatic, non-smoker, 16-year-old male came for medical attention because of odynophagia and pain located at anterior cervical area and upper retrosternal area, increasing with swallowing and deep breathing, that begun after physical exercise at gymnastic class. The adolescent also mentioned a felling of air bubbles running up and down that area. There was no history of local trauma. He referred stuffed nose and mild cough but no other respiratory complaints or fever. Physical examination was unremarkable, with normal auscultation and no alterations on cervical and thoracic examination. Lateral soft tissue neck X-ray revealed free air in retropharyngeal space (figure 1, arrows). Chest X-ray showed a small amount of air in the upper mediastinum. Blood count was normal, and C reactive protein was negative. Mycoplasma pneumoniae IgM was negative. The patient was treated with high concentration oxygen and oral analgesia. The next day, he...

Food-dependent exercise-induced anaphylaxis

Food-dependent exercise-induced anaphylaxis (FDEIAn), first reported in 1979, is a condition defined by the consumption of a trigger food with temporally related exercise that results in an immediate hypersensitivity (type 1) reaction in the setting of the trigger food being tolerated independent of exercise and exercise being tolerated in the absence of trigger food consumption. The most common trigger food in the west is wheat and shellfish in Asia. The exact mechanism of FDEIAn is unknown, though several hypotheses exist. Cofactors such as non-steroidal anti-inflammatory drug use, alcohol consumption and others have been associated with reported cases.

Inadvertent inflation of Foley catheter balloon with contrast: an error that caused unnecessary apprehensions

Description 

A 30-year-old male patient underwent percutaneous nephrolithotomy (PCNL) for a 3.5 cm right renal calculus. As per our institutional protocol he underwent a check X-ray the next day. The relatives of the patient immediately came to us asking whether some residual fragments of the calculus were there in the urinary bladder. When we reviewed the X-ray film, there was a radio-opaque shadow with a smooth contour in the region of urinary bladder. On careful examination this shadow was continuous with a radio-opaque line along the Foley catheter (figure 1). We immediately removed the Foley catheter and did another check X-ray. The shadow had disappeared. We then realised that the catheter's balloon was inflated with contrast solution prepared for fluoroscopy-guided puncture during PCNL. We acknowledged this error to the patient and his relatives and explained them how sorry we were for their anxiety, following which they were...

Arthroscopic reduction and fixation of a lateral inverted osteochondral fracture of the talus ('LIFT)

Some ankle sprains hide important lesions beyond the classic lateral ligament complex injuries. The lateral inverted osteochondral fracture of the talus (LIFT) represents a rare osteochondral lesion, whose diagnosis relies on a high clinical suspicion followed by correct image study interpretation. We present a successful arthroscopic fixation of a LIFT lesion in a 45-year-old active man. At 8 months follow-up, the patient was pain free and able to return to his daily activities without limitation. The imagiological study showed osteochondral fragment consolidation with no signs of hardware failure. This midterm results reassemble the need for early diagnosis and correct treatment to achieve a good outcome in these complex and rare osteochondral lesions.

Rare and unexpected complication after a malpositioned nasogastric tube in a neonate

Description

A full-term newborn boy was admitted to the high dependency unit at the age of 4 hours with signs of respiratory distress, tachypnoea and recession with low oxygen saturation. There was no perinatal history of concerns; delivery was normal and uneventful, but the mother was colonised with Group B streptococcus.

A plan was made on admission for a chest X-ray, a nasogastric tube (NGT) insertion and antibiotics. NGT was placed by a senior neonatal nurse without incident, followed by chest X-ray primarily looking for respiratory causes of the respiratory distress. This however revealed that the NGT was malposed into the right main bronchus (figure 1). There were no signs of choking or cough at the time of insertion. NGT was then pulled out and a new one reinserted in a satisfactory position and confirmed on a repeat chest X-ray (figure 2). A right-sided small and...

Orbital metastasis from an occult breast carcinoma (T0, N1, M1)

The authors report a case of an orbital metastasis from an occult breast carcinoma. A 66-year-old woman presented with a growing left orbital tumour. Orbital CT scan was consistent with lymphoma. However, ocular pathology revealed small neoplastic cells showing an 'indian file pattern' suggestive of metastatic carcinoma and immunohistochemistry was positive for CK7, CK CAM5.2 and oestrogen receptor. A systemic evaluation was then performed with mammogram, breast ultrasound and MRI considered normal. An exhaustive systemic evaluation revealed multiple bone lesions, a right axillary lymph node lesion, which presented the same pattern on pathology and immunohistochemistry, with no evidence of a primary tumour. A diagnosis of a metastatic lobular carcinoma of the breast (T0, N1, M1) was made and the patient was started on chemotherapy and adjuvant hormonal therapy.

Treatment-refractory ALK-positive inflammatory myofibroblastic tumour of the oral cavity

We present a challenging case of a previously healthy 23-year-old man who developed an inflammatory myofibroblastic tumour of the hard palate, harbouring a rearrangement of the anaplastic lymphoma kinase (ALK) locus. Despite surgical intervention, radiotherapy and ALK-inhibition therapy, the tumour recurred locally and metastasised to regional lymph nodes, and the patient passed away roughly 9 months after diagnosis from local progression. The rapid progression of this patient's disease and its resistance to treatment demonstrate the potentially aggressive clinical course of inflammatory myofibroblastic tumours. ALK-inhibition therapy was unsuccessful in this ALK-positive tumour, highlighting the need for further investigation of markers predictive of disease progression and treatment response.

Sphingomonas paucimobilis empyema caused by remote foreign body aspiration

Empyema secondary to foreign body aspiration is rare in adults. We present a case of empyema in a 77-year-old male patient related to a remote aspiration event during a dental procedure. A CT of the chest and bronchoscopy confirmed that a metallic foreign body was located within the right lower lobe bronchus. His pleural fluid culture revealed Sphingomonas paucimobilis which is a low-virulent opportunistic gram-negative bacilli and rarely causes infection. The patient received meropenem followed by levofloxacin and recovered uneventfully. The attempt of foreign body removal was failed due to chronic inflammation, and the patient refused further surgical management.

Peripherally inserted central catheter (PICC) placement: beware of the bends

Description 

The peripherally inserted central catheter (PICC) is used as a long-term vascular access to deliver medications and venous nutrition. The PICC tip terminates close to the heart or in one of the great vessels—the superior vena cava or the inferior vena cava. Catheter tip confirmation is usually achieved by plain radiography. We describe a case of a 9-month-old boy with complex congenital heart disease (heterotaxy syndrome, polysplenia type) who underwent pulmonary artery banding to reduce pulmonary blood flow to control heart failure symptoms. PICC was placed in the left femoral vein during the postoperative period. PICC tip confirmation was obtained by anteroposterior plain abdominal radiograph (figure 1), which demonstrated catheter tip bending at T12. The lateral radiograph of the abdomen showed that the PICC courses posteriorly into the lumbar venous plexus (figure 2). The ascending lumbar veins arises at L5–S1 from the common iliac vein and drains into...

Improvement of thoracic myelopathy following bariatric surgery in an obese patient

Revision spine surgery is extremely challenging in super-super obese patients (body mass index (BMI) ≥60 kg/m2). This is the first report describing how bariatric surgery was useful for a super-super obese patient with progressing myelopathy. A 44-year-old man with a BMI of 62.9 kg/m2 presented with an ambulatory disorder caused by thoracic ossification of the posterior longitudinal ligament (T7–8). Before this paraparesis, he had undergone four spinal operations, and was not considered a good candidate for a fifth spine surgery. At the time of the fourth operation, he had reached a maximum weight of 205 kg (BMI 69.3 kg/m2). Instead, he underwent a laparoscopic sleeve gastrectomy. Sixteen months later, his body weight had decreased to BMI 35.2 kg/m2, and he could walk without a walker. In addition to reducing our patient's load, a 'non-operative' form of dekyphosis due to altered thoracic spinal alignment secondary to weight loss may explain the improvement in his myelopathy.

Spontaneous rectus sheath haematoma due to cough on apixaban

Description 

A 69-year-old woman on apixaban for 4 years due to her atrial fibrillation presented with severe left lower abdominal pain. She was discharged from the hospital 4 days prior after treatment for influenza and had finished a course of oseltamivir. She did not receive any heparin products and was continued on apixaban during that admission. A few hours before presentation, she reported coughing severely with sudden onset of excruciating abdominal pain. She denied trauma or injury to the abdomen. On exam, she was alert, normotensive and tachycardic, with significant left lower quadrant tenderness in the abdomen. Laboratory results were significant for decreased haemoglobin from 15.2 to 12.9 g/dL. CT of the abdomen showed acute left inferior rectus abdominis muscle haematoma (7.5 cm), along with stable and unchanged left adnexal cystic lesion (figure 1). Apixaban was discontinued, and the patient was closely monitored in the hospital with supportive care....

Pseudoaneurysm of the gastroduodenal artery: an unusual cause for hyperamylasaemia

A 79-year-old man was admitted electively for investigation of weight loss. While he was an inpatient, he developed severe epigastric pain and an initial blood test revealed an acutely raised amylase (>2000) and deranged liver function tests. A contrast CT angiography showed a large haematoma adjacent to the duodenum, spreading in the retroperitoneal space, arising from a 2 cm bleeding pseudoaneurysm in the region of the gastroduodenal artery. Due to his underlying comorbidities, he was deemed unfit for surgical repair and he had coil embolisation with successful haemostasis. The gastroduodenal artery aneurysms are rare and constitute 1.5% of all visceral artery aneurysms. They can be an incidental finding or they can present with haemorrhagic shock, abdominal pain and rarely with obstructive jaundice or hyperamylasaemia. The diagnosis is usually made with an angiography. Variable treatment options are available depending on the patient's fitness and haemodynamic stability.

Single coronary artery with bicuspid aortic valve

Description

A 45-year-old man with known history of coronary artery disease and bicuspid aortic valve (BAV) (figure 1) was admitted for worsening symptoms of angina. Coronary angiogram showed single coronary artery arising from the left cusp, trifurcating into right coronary artery, left anterior descending (LAD) and left circumflex artery (LCx) (figure 2). No course of the left main coronary artery between the aortic root and the pulmonary artery was noted. There was obstructive disease in proximal LAD (70%), first diagonal artery (80%) and proximal LCx (70%). Peak gradient of 51 mm Hg across the BAV was registered. He underwent bypass graft surgery along with an aortic valve replacement successfully.

Thyroid Function Screening in Children With Alopecia Areata—Reply

In Reply We appreciate the interest of Drs Rustagi and Weiss in our proposed screening guidelines for thyroid function in children with alopecia. We have noted that many blood tests are performed in children with alopecia areata who have no symptoms outside of their hair loss, and so the goal of our article was to suggest a reduction in the number of patients who are being screened for thyroid disease when they present with alopecia areata. We stand by our conclusions that the specific subpopulation of patients who have both alopecia areata and trisomy 21 should undergo thyroid screening at the occurrence of new-onset alopecia areata if they have not had recent screening. The association between Down syndrome and thyroid disorders is well recognized, and patients with Down syndrome have an increased prevalence of both congenital hypothyroidism and acquired thyroid dysfunction, with hypothyroidism being most common. The American Academy of Pediatrics recommends screening at age 6 months, age 12 months, and annually thereafter or at the development of new symptoms. We found a statistically significant association between Down syndrome in patients with alopecia areata who also had thyroid abnormalities.

Thyroid Function Screening in Children With Alopecia Areata

To the Editor In their recent article in JAMA Dermatology, Patel et al describe the prevalence of thyroid disorders among subgroups of children with alopecia areata (eg, those with Down syndrome), and interpret the findings as justification for screening such children. Unfortunately, the authors did not attempt to exclude children presenting with symptoms of thyroid dysfunction (eg, heat or cold intolerance, fatigue, growth abnormalities). Indeed, a category of thyroid dysfunction among the 59 patients with abnormal results was "subclinical thyroid dysfunction," implying that the other patients may have had clinical signs or symptoms of thyroid disease. Since screening, by definition, is conducted among asymptomatic individuals, the results reported by Patel et al cannot be interpreted to support or refute screening guidelines. Children with symptoms of thyroid dysfunction are more likely to receive thyroid function tests and are also more likely to have thyroid dysfunction; therefore, the true prevalence of thyroid disorders among asymptomatic children with alopecia areata who receive thyroid screening is expected to be lower than the estimates in this study. Whether the true prevalence is high enough in certain subgroups to justify screening cannot be determined from the data presented.

ObjectiveThe purpose of this study was to compare the effects of the oral administration of natural curcumin and a chemically modified curcumin (CMC2.24) on osteoclast-mediated bone resorption, apoptosis, and inflammation in a murine model of experimental periodontal disease.DesignFifty male rats were distributed among the following treatment groups: (i) 2% carboxymethylcellulose, (ii) CMC2.24 30 mg/Kg body weight, (iii) Curcumin 100 mg/Kg body weight and (iv) no treatment. Compounds were administered daily by oral intubation over a 15-day period of time. Periodontal disease was induced by injections of LPS (lipopolysaccharide) into the gingival tissues three times per week. Contralateral sides were injected with the same volume of PBS (phosphate buffered saline) vehicle. After 15 days, hemimaxillae and gingival tissues were harvested. Bone resorption was assessed by μCT (microcomputer tomography). Formalin-fixed, paraffin embedded histological sections were stained with haematoxylin/eosin (H/E) for the assessment of cellular infiltrate or subjected to immunohistochemistry for detecting TRAP (tartrate-resistant acid phosphatase)-positive cells and caspase-3. Apoptosis was assessed in the gingival tissues by DNA fragmentation.ResultsCMC2.24 and curcumin caused a significant reduction of the inflammatory cell infiltrate, however μCT analysis showed that only CMC2.24 reduced bone resorption and the number of TRAP-positive multinucleated cells (osteoclasts). Curcumin, but not CMC2.24, significantly reduced the number of apoptotic cells in the gingival tissues and of osteocytes in the alveolar bone crest.ConclusionsThe results suggest that CMC2.24 and curcumin inhibit inflammation by different mechanisms, but only CMC2.24 was capable of reducing alveolar bone resorption in the LPS-induced model of periodontitis.

The Vedic View of Vitiligo

Throughout antiquity, many causes of leukoderma, including vitiligo and leprosy, were thought to be the negative result of a prior action in life. In the Old Testament Book of Leviticus, "white spots" were arguably considered as a punishment by God for having committed a mortal sin, and the consequence for that was to be an outcaste. Around the same time period, in his book Clio, the Greek historian Herodotus wrote "if a Persian has leprosy or white sickness he is not allowed to enter into a city or to have dealings with other Persians [for] he must have sinned against the sun." This all-too-familiar theme appeared again a thousand years later in the ancient Hindu texts, the Puranas, when Samba, the son of Lord Krishna, is cursed with "white leprosy" by the sage Durvasa for mocking him, or, depending on which version of the Puranas you read, is cursed by Lord Krishna for lack of propriety. Regardless of the inciting insult, all versions of the Puranas note that Samba was cured of "white leprosy" after he worshipped the sun god, Surya. Although it is impossible to be certain, it is likely that the Persian "white sickness" and Hindu "white leprosy" refer to vitiligo.

A Skeptical Approach to the Management of Persistent Oral Ulceration in a Child

The diagnosis of oral lesions is sometimes difficult due to both the clinician's limited experience with the conditions that may cause the lesions and their similar appearances, especially in children. Correctly establishing a definitive diagnosis is of major importance to clinicians who manage patients with oral mucosal diseases. In patients with Fanconi anaemia (FA), oral ulcers occur frequently, which are quite variable, and may lead to a misdiagnosis or failure to diagnose. Here, we report the case of a 15-year-old boy who was examined for squamous cell cancer of the tongue and diagnosed as having FA without any haematological manifestations. While surgery could not be done, both radiotherapy and chemotherapy had to be decreased. He died of progressive disease 6 months after the diagnosis. Unexplained ulcers in a child with a duration longer than 2 weeks should be further evaluated, especially for FA, even without the presence of anaemia.

Because of the anatomical location, patients with head and neck cancer (HNC) frequently experience dysphagia and malnutrition at the time of diagnosis and these conditions are often exacerbated after chemoradiotherapy. There is an emerging medical need to establish a consensus on nutritional intervention for these patients. A panel of 30 senior physicians and experts from multidisciplinary teams drafted clinical recommendations to improve the management of nutritional interventions in Taiwan and to provide updated treatment strategy recommendations in hope of improving the nutritional status of patients with HNC. This clinical review describes the resulting consensus document, including the impact of malnutrition on clinical outcomes, the role of prophylactic tube feeding, the choice of tube feeding, and the benefit of oral nutritional supplements in patients with HNC undergoing chemoradiotherapy. The outcomes of this review will support clinicians in their efforts to improve the nutritional status of patients with HNC.

Background and objectivesT4 squamous cell carcinomas of the buccal mucosa is known to have ominous outcome. The aim of this study was to develop a nomogram for T4 buccal mucosa cancer patients and demonstrate the difference in survival based on prognosticators beyond those covered by the traditional TNM staging system.MethodsWe examined medical records of treatment naïve 205 T4 buccal mucosa cancer patients operated between January 1, 2009, and December 31, 2014. A nomogram was developed using multivariate cox-regression. The nomogram was validated internally by bootstrapping and externally in an independent validation set.ResultsThe nomogram for predicting 3-year overall survival was built using Tumor differentiation, Pathological Lymph node involvement, Bone and Perineural invasion. Based on nomogram, a score was assigned to each patient and they were divided into two groups based on Youden derived cut-off value (13.5). These two groups in training and validation set showed significant difference in survival.ConclusionWe developed a high performance, accurate and efficient nomogram to predict the probability of 3-year survival in T4 buccal mucosa cancer patients. Intensification of adjuvant treatment in these advanced cancer patients with poorer score might improve their survival.

Objectives3D virtual surgical planning (VSP) and guided surgery has been proven to be an effective tool for resection and reconstruction of the mandible. Currently, most widely used 3D VSP approaches to mandibular resection do not include detailed tumour information in the VSP. This manuscript presents a strategy where the aim was to incorporate tumour visualisation into the 3D virtual plan. Three-dimensional VSP of the mandibular resections was based on the fusion of CT and MRI data which was subsequently applied in clinical practice.MethodsAll patients diagnosed with oral squamous cell carcinoma between 2014 and 2017 at the University Medical Centre Groningen were included. The tumour was delineated on the MRI data, after which this dataset was fused with the CT bone data in order to construct a 3D bone and tumour model for virtual resection planning. Guided resections were performed and post-operative evaluation quantified the accuracy of the resection. The histopathological findings and patient and tumour characteristics were compared to those of a historical cohort (2009–2014) of conventional mandibular continuity resections.ResultsTwenty-four patients were included in the cohort. The average deviation from planned resection was found to be 2.2 mm. Histopathologic analysis confirmed all resection planes (bone) were tumour free, compared to 96.4% in the historic cohort.ConclusionMRI-CT base tumour visualisation and 3D resection planning is a safe and accurate method for oncologic resection of the mandible. It is an improvement on the current methods reported for 3D resection planning based solely on CT data.

ObjectivesSecondary oral squamous cell carcinoma (OSCC) is a late complication in allogeneic hematopoietic stem cell transplantation (HSCT) patients, but little is known about long-term outcomes and prognostication. Additionally, molecular alterations and immunologic insights unique to this disease remain largely unexplored.MethodsWe present a cohort of 31 patients with post-HSCT OSCC and reported on clinicopathologic predictors of survival. Whole-exome sequencing was performed on 6 (19%) matched pairs of peripheral blood (post-conditioning, pre-HSCT) and tumor samples. The entire cohort had archival tumor available for immunoprofiling with PD-1/L1 immunohistochemistry.ResultsFive-year overall survival (OS) was 57% (95% CI: 46.1–69.8) with a median disease-free survival (DFS) of 13.3 months. Advanced initial staging, a buccal or oral tongue subsite, chronic oral graft-versus-host disease (GVHD) and smoking all negatively impacted survival. High tumor mutational burden (TMB) (median 11.3 vs. 5.0) and unique mutational signatures were noted between unrelated and related donor groups – with a strong correlation between infiltrating PD-1+ lymphocytes and TMB (R = 0.98, p < 0.01). Some differences were observed when comparing commonly mutated genes among our cohort and TCGA, with a predominance of TP53 events.ConclusionSurvival outcomes appear similar in HSCT survivors with OSCC compared with non-HSCT OSCC populations. We identified somatic alterations in genes with therapeutic potential unique to this subpopulation of oral cancers.

BackgroundImmunotherapy for food allergies involves progressive increased exposures to food that result in desensitization to food allergens in some subjects but not tolerance to the food. Therefore new approaches to suppress allergic immunity to food are necessary. Previously, we demonstrated that intranasal immunization with a nanoemulsion (NE) adjuvant induces robust mucosal antibody and TH17-polarized immunity, as well as systemic TH1-biased cellular immunity with suppression of pre-existing TH2-biased immunity.ObjectiveWe hypothesized that immunization with food in conjunction with the nanoemulsion adjuvant could lead to modulation of allergic reactions in food allergy by altering pre-existing allergic immunity and enhancing mucosal immunity.MethodsMice were sensitized to peanut with aluminum hydroxide or cholera toxin. The animals were then administered 3 monthly intranasal immunizations with peanut in the nanoemulsion adjuvant or saline. Mice were then challenged with peanut to examine allergen reactivity.ResultsThe NE intranasal immunizations resulted in marked decreases in TH2 cytokine, IgG1, and IgE levels, whereas TH1 and mucosal TH17 immune responses were increased. After allergen challenge, these mice showed significant reductions in allergic hypersensitivity. Additionally, the NE immunizations significantly increased antigen-specific IL-10 production and regulatory T-cell counts, and the protection induced by NE was dependent in part on IL-10. Control animals immunized with intranasal peanut in saline had no modulation of their allergic response.ConclusionsNE adjuvant–mediated induction of mucosal TH17 and systemic TH1-biased immunity can suppress TH2-mediated allergy through multiple mechanisms and protect against anaphylaxis. These results suggest the potential therapeutic utility of this approach in the setting of food allergy.

Personalized cancer vaccines: adjuvants are important, too

Abstract

Therapeutic cancer vaccines have shown limited clinical efficacy so far. Nevertheless, in the meantime, our understanding of immune cell function and the interactions of immune cells with growing tumors has advanced considerably. We are now in a position to invest this knowledge into the design of more powerful vaccines and therapy combinations aimed at increasing immunogenicity and decreasing tumor-induced immunosuppression. This review focuses essentially on peptide-based human vaccines. We will discuss two aspects that are critical for increasing their intrinsic immunogenicity: the selection of the antigen(s) to be targeted, and the as yet unmet need for strong adjuvants.

Aim and scopeBilateral non-traumatic temporo-mandibular joint (TMJ) dislocation is an acute situation that can lead to a chronic and recurrent condition. Few paediatric cases have been reported in the literature and no standardized care protocol has been established to date.Material and MethodsTwo cases of chronic bilateral dislocation of the TMJ in young children are reported and their medical management is discussed based on data from the literature.ConclusionTMJ dislocations in children raise specific concerns such as the need for screening for underlying congenital disorders of connective tissues. Surgical options in children are furthermore very limited. Here we proposed an indicative management protocol for recurrent joint dislocation in pediatric populations based on two new cases and the data from the literature.

CTA perforator localization for virtual surgical planning of osteocutaneous fibular free flaps in head and neck reconstruction

Virtual surgical planning (VSP), computer aided design (CAD)/computer aided modeling (CAM), and 3D printing are three distinct technologies that have become increasingly employed within head and neck oncology and microvascular reconstruction. While each of these technologies have long been utilized for treatment planning within other surgical disciplines such as craniofacial surgery, trauma surgery, temporomandibular joint surgery, and orthognathic surgery, its widespread use within the field of head and neck reconstructive surgery remains a much more recent event.In response to the growing trend of VSP being employed for the planning of fibular free flaps within head and neck reconstruction, some surgeons have questioned the technology's implementation on the basis of its inadequacy in addressing other reconstructive considerations beyond hard tissue anatomy. Detractors of VSP for head and neck reconstruction highlight its lack of capability in accounting for multiple reconstructive factors such as recipient vessel selection, vascular pedicle reach, need for dead space obliteration, and skin paddle perforator location. It is with this premise in mind that that we report a straightforward technique for anatomically localizing peroneal artery perforators during virtual surgical planning for osteocutaneous fibular free flaps where both bone and a soft tissue skin paddle are required for ablative reconstruction. The technique allows for anatomical perforator localization during the virtual surgical planning session solely based on data existent within the preoperative computed tomographic angiography (CTA); it does not require any modifications to preoperative clinical workflows. It is our presumption that many surgeons within the field are unaware of this planning capability within the context of modern VSP for head and neck reconstruction. The primary purpose of this manuscript is to introduce and further familiarize surgeons with the technique of CTA perforator localization as a method of improving intraoperative fidelity for virtual surgical planning of osteocutaneous fibular free flaps.

PurposeTo describe the safety and effectiveness of nasotracheal intubation (NTI) in a cohort of patients undergoing reconstruction of oral cavity defects with free tissue transfer (FTT).MethodsThe authors implemented a retrospective cohort study and enrolled a sample composed of consecutive patients undergoing FTT reconstruction of oral cavity, maxillary, or mandibular defects between 2013 and 2017. These patients were all subject to a newly developed Enhanced Recovery After Surgery (ERAS) protocol. The primary outcome measurement was hospital length of stay (LOS). Secondary outcome variables were the duration of mechanical ventilation, intensive care unit (ICU) LOS, need for gastrostomy, and airway-related complications directly associated with either NTI or tracheostomy. Descriptive statistics and a multivariate logistic regression analysis were completed.ResultsThe sample was composed of 141 patients that had undergone oral cavity FTT for both benign and malignant diseases (NTI, n=111; tracheostomy, n=30). Patients managed with NTI had a statistically significant shorter hospital LOS (8 vs.15.5 days; P<0.0001), ICU LOS (1 vs. 2 days; P=0.0006), and a decreased requirement for gastrostomy (17.1 vs. 76.7%; P<0.0001). Airway-related complications were rare in both the tracheostomy (13.3%) and NTI (3.6%) groups. Multivariate analysis demonstrated that patients undergoing tracheostomy were 3.14 (P=0.004) times more likely to have a prolonged hospitalization and 10.4 (P<0.0001) times more likely to require a gastrostomy. A sensitivity analysis of patients' with malignant diagnoses only had similar statistically significant results. The delayed tracheostomy rate in the NTI group was 3.6%.ConclusionTo date, this is the largest study to evaluate the use of NTI in patients undergoing oral cavity reconstruction with FTT. Our results suggest, that in the appropriate institutional setting, the majority of patients can be safely managed with NTI. This approach results in a decreased hospital and ICU LOS and an earlier resumption of oral intake with less need for gastrostomy.
