The neuroplastic effect of olfactory training to the recovery of olfactory system in mouse model

Background

Several studies have reported the benefits of olfactory training (OT) in the olfactory nervous system of mouse models. Therefore, in this study we performed next‐generation sequencing to evaluate the effects of OT on mRNA sequencing in the olfactory area.

Methods

Mice in each group were administered 300 mg of 3‐methylindole per kilogram of mouse weight. The olfactory function was evaluated by a food‐finding test once a week. The olfactory neuroepithelium was harvested for histologic examination and protein analysis. Subsequently, data analysis, gene ontology and pathway analysis, quantitative real‐time polymerase chain reaction of mRNA, and Western blot analysis were conducted.

Results

Mice were divided into 4 groups according to treatment. Control, anosmia, training, and steroid group mice resumed food finding. Olfactory Maker Protein, olfr1507, ADCY3, and GNAL mRNA expression was higher in the olfactory neuroepithelium of OT than anosmia group mice. In total, 26,364 mRNAs were analyzed. Comparison of the results of OT vs anosmia revealed that ADCY8,10, GFAP, NGF, NGFR, GFAP, and BDNF mRNAs were upregulated in the gene ontology.

Conclusion

OT improved olfactory function, as indicated by the food‐finding test. OT improved the olfactory recovery time to stimulate olfactory nerve regeneration. OT may initially stimulate the olfactory receptor, followed by neurogenesis. Steroid therapy and OT operated under completely different mechanisms in the upregulated gene study. These results indicate that OT may be one of the future modalities for treating olfactory impairment.

Accuracy of crowns based on digital intraoral scanning compared to conventional impression—a split-mouth randomised clinical study

Abstract

Objectives

The aim of this prospective in vivo study was to evaluate the accuracy of the marginal and internal fit of crowns based on conventional impression (CI) or intraoral scan (IOS) in a randomised, split-mouth set-up.

Materials and methods

Nineteen patients needing full coverage crowns, fitting a split-mouth design, were provided with two lithium disilicate crowns: one based on a CI and one based on an IOS. The marginal and internal accuracy of the crowns were assessed with the replica technique and clinically using a modified California Dental Association (CDA) quality evaluation system.

Results

At the preparation margin, the median gap was 60 μm for IOS and 78 μm for CI. For the other points, the median gap ranged from 91 to 159 μm for IOS and 109 to 181 μm for CI. The accuracy of the IOS was statistically significantly better at all point except at the cusp tip. All crowns where rated R or S at both the 6- and 12-month follow-up appointments. The results for the clinical evaluation with CDA for marginal integrity showed no statistically significant difference between the two impression methods at both the 6- and 12-month evaluations.

Conclusions

Crowns based on IOS show statistically significantly better marginal and internal adaptation before cementation compared to conventional impression. However, the clinical evaluation showed similar marginal adaptation.

Clinical relevance

Crowns based on a fully digital workflow can provide clinically acceptable marginal adaptation, comparable to crowns based on CI.

Precision Medicine in Rhinosinusitis

Abstract

Purpose of Review

Our scope is the presentation of research and clinical progresses in relation to precision medicine that are expected to alter our clinical practice in relation to chronic rhinosinusitis (CRS). Current knowledge on phenotypes and endotypes, biomarkers, and clinical markers for diagnosis, medical and surgical therapy, and prognosis is presented as well as the role of precision medicine in United Airway Disease and SCUAD (severe-uncontrolled chronic upper airway inflammation).

Recent Findings

Current technological progresses, mostly in relation to molecular biology and information technology, have permitted more detailed pathophysiological assessments and multidimensional approaches in airways diseases. Based on the concept of united airways diseases, new classification schemes, called endotypes, have been proposed for CRS. In addition, novel biological treatments that have been introduced for the treatment of asthma show great promise as well for severe uncontrolled cases of CRS with nasal polyps. Central to this approach are new biomarkers that are being examined in relation to complex bio-clinical traits of CRS.

Summary

As this narrative review of the aforementioned precision medicine initiatives in relation to CRS advances, a modification of current practice is expected not only for severe chronic upper airways diseases in tertiary centers but also for milder and more common cases that are being encountered in the community.

Clinical Guidelines on Chronic Rhinosinusitis in Children

Abstract

Purpose of Review

Pediatric chronic rhinosinusitis (CRS) is a prevalent problem that can elude diagnosis. In addition, given the burgeoning interest in pediatric sinonasal disease, treatment modalities are constantly evolving.

Recent Findings

The diagnosis of pediatric CRS is primarily based on clinical history and signs supported by objective findings (i.e., nasal endoscopy and/or computed tomography (CT) imaging). Cultures are indicated in patients who have not responded to medical therapy or have significant comorbidities. Nasal saline irrigation, nasal saline spray, and oral antibiotics are currently recommended for initial medical management. In children with CRS who have failed medical therapy, a stepwise approach to surgical intervention can lead to significant improvements in quality of life.

Summary

This review provides an overview of the current guidelines and recent literature regarding the diagnosis, microbiology, and treatment options of CRS in the pediatric population.

Hypoallergenic Proteins for the Treatment of Food Allergy

Abstract

Purpose of Review

Food allergy is a growing health problem worldwide that impacts millions of individuals. Current treatment options are limited and strict dietary avoidance remains the standard of care. Immunotherapy using whole, native allergens is under active clinical investigation but harbors the risk of severe side effects including anaphylaxis. Newer food-specific therapies with hypoallergenic proteins may potentially offer safer treatment alternatives, and this review seeks to investigate the evidence supporting the use of these modalities.

Recent Findings

The utilization of different methods to alter allergen structure and IgE binding leads to reduced allergenicity and decreases the risk for systemic reactions, making the use of potential therapies including extensively heated egg/milk, peptide immunotherapy, recombinant allergen immunotherapy, and DNA vaccines safe and possibly efficacious forms of treatment in food allergy. However, for the majority of these treatment modalities, limited data currently exists looking at the safety and efficacy in human subjects with food allergy.

Summary

This review provides a comprehensive overview of the current evidence examining the safety and efficacy of hypoallergenic proteins in the treatment of food allergies.

Multimorbidities of Pediatric Allergic Rhinitis

Abstract

Purpose of Review

Most children and adolescents with allergic rhinitis (AR) present extra-nasal multimorbid conditions, including conjunctivitis, asthma, atopic dermatitis, rhinosinusitis, or seromucous otitis. Additionally, they may present nasal obstructive disorders, such as septal deformity, turbinate enlargement, and adenoidal hyperplasia, which worsen nasal symptoms, especially nasal obstruction. This is a narrative review on the current state of the concomitant presence of AR and one or more multimorbidities.

Recent Findings

The presence of AR and one or more accompanying multimorbidities is associated to a higher severity and duration of the disease, a negative impact on quality of life, with worse control and lack of improvement with medical treatment. Therefore, AR needs to be managed with a multidisciplinary collaborative approach.

Summary

Pediatric AR needs to be considered in the context of a systemic disease, which requires a coordinated therapeutic strategy.

Neurosyphilis presenting as cranial nerve palsy, an entity which is easy to miss

Neurosyphilis is a rare disease that until the 2000s was almost eradicated due to population awareness of HIV and efficient treatment. Since then, the prevalence of the entity is rising due to risk-associated behaviour such as unprotected intercourse. Neurosyphilis is still a difficult entity to diagnose especially when combined with acute HIV infection which can influence the usual clinical course of disease. In rare occasions, both acute HIV and early syphilis infection can present as mono or multiple cranial nerve palsies. This case demonstrates a rare manifestation of misdiagnosed early syphilis infection combined with acute HIV infection in a 34-year-old man with prior history of unprotected sex with men.

Resistant dermatomyositis in a rural indigenous Maya woman

A 28-year-old indigenous Guatemalan woman presented with 7 months of progressive weakness and numerous dermatological findings. She initially sought care within the free government-run health system and was treated with oral steroids for presumed dermatomyositis. Her symptoms progressed, including severe dysphagia, hypophonia and weakness preventing sitting. She was lost to follow-up in the public system due to financial and cultural barriers. A non-governmental organisation tailored to the needs of Maya patients provided home intravenous pulse dose methylprednisolone in the absence of first-line biologicals. With longitudinal home-based care, she achieved symptom free recovery. The rising burden of chronic non-communicable diseases highlights shortcomings in health systems evident in this case, including lack of provider capacity, limited infrastructure to test for and treat rare diseases and poor continuity of care. We provide potential solutions to help care delivery in low-resource settings adapt to the demans of chronic disease control with particular attention to social determinants of health.

Bilateral acute non-obstructive pyelonephritis presenting as acute kidney injury requiring haemodialysis

A 54-year-old female patient with hypothyroidism and diabetes mellitus type 2 was brought to emergency room by the family members for acute change in mental status. The laboratory evaluation demonstrated findings consistent with acute renal failure (normal renal function 3 months prior to presentation). She was initiated on hemodialysis due to lack of improvement in renal function. Urine culture done prior to initiation of antibiotics was positive for Escherichia coli, which was later confirmed by renal biopsy. Extensive workup for the cause of renal failure including for connective tissue disease, plasmacytoma, obstruction was negative. She was treated with 6 week course of antibiotics with eventual recovery of her renal function in 4 months.

Unknown primary Merkel cell carcinoma with cutaneous spread

The authors present the case of a woman in the seventh decade of life with medical history of: left nephrectomy for renal tuberculosis and non-Hodgkin's lymphoma treated with chemotherapy (QT) and radiotherapy. She presented with a 2-month history of non-tender, left inguinal lymph node enlargement. Positron Emission Tomography (PET)—CT —scanshowed hypermetabolic inguinal and retroperitoneal lymphadenopathies, no primary tumour. On the second dermatological examination a pink, 2 cm plaque on the anterior left knee was noted. The histopathological analysis revealed Merkel cell carcinoma. The patient underwent two lines of systemic QT, with life-threatening toxicities limiting treatment. Followed overwhelming disease progression with lymphoedema and numerous skin metastases in the left lower limb. The patient received palliative care until death. The rare incidence of such neoplasia and its uncommon clinical presentation justifies reporting this case and highlights the importance of multidisciplinary teams in the management of cancer patients.

Use of home telemedicine for critical illness rehabilitation: an Indian success story

One-fifth of healthcare beneficiaries in developed nations get discharged from hospitals to physician supervised skilled nursing care facilities. In low-income and middle-income countries like India, postdischarge skilled nursing facilities are at a very nascent stage and largely underequipped in terms of infrastructure, skilled nursing and physician staff to manage complicated patients. Hence the responsibility of management of such patients lies largely with their families. We present a case where a 26-year-old man with Duchenne Muscular Dystrophy who became ventilator dependent following major surgeries was weaned off his ventilator and rehabilitated back to his prehospital state. This was done at his home with visiting nurses and rehabilitation services under telemedicine supervision by a critical care specialist. Use of telemedicine services could be a viable and cost-effective option to ensure adherence to evidence-based medicine and standardisation of care in resource limited countries such as India.

Iatrogenic adrenal suppression following caudal epidural and facet joint injection

Caudal epidural injections and facet joint injections using steroids and local anaesthetic are widely used methods of pain control in patients suffering from radicular leg pain. In the vast majority of cases this is low risk. We present an interesting case of a patient who suffered from symptomatic adrenal suppression following a caudal epidural injection, and thus wish to draw this rare but significant complication to the attention of orthopaedic practitioners.

Scrotal necrosis and no Fourniers in sight: a rare case of juvenile gangrenous vasculitis

Juvenile gangrenous vasculitis of the scrotum is a rare entity, of which to our knowledge we describe the first documented case in the UK. It follows a typical disease course, demonstrated by an 18-year-old male who presented with three necrotic scrotal lesions; proceeded by 3 days of fever, pharyngitis and lethargy. Previous cases have been managed successfully with systemic steroids. On this occasion, surgical debridement was made of the necrotic areas under antibiotic cover and complete resolution was achieved with excellent wound healing and no evidence of recurrence. This case report discusses the importance of disease recognition and the merits of surgical management. We also add to the debate as to whether this disease is a variation of pyoderma gangrenosum or a distinct entity itself within the pantheon of scrotal gangrene.

Drug-induced paraspinal myositis mimicking acute bilateral sciatica

Although cocaine induced myopathy and myotoxicity are described in the literature, we report a rare case of cocaine induced paraspinal myositis presenting with acute sciatic symptoms. A 35-year-old man presented with acute left-sided sciatica and was discharged from the emergency department (ED). He subsequently attended ED the following day in severe pain and bilateral sciatic symptoms, but denied symptoms of neurogenic bowel/bladder disturbance. Clinical examination was limited by severe pain: focal midline lumbar tenderness was elicited on palpation, per rectal and limb examinations were within normal limits with no significant neurological deficit. He was admitted for observation and pain management. His blood tests revealed a leucocyte count of 21.5x109/L, C reactive protein of 89 mg/L and deranged renal function with creatinine of 293 μmol/L. An urgent lumbar spine MRI was arranged to rule out a discitis or epidural abscess. Lumbar MRI did not demonstrate any features of discitis but non-specific appearances of paraspinal inflammation raised the suspicion of a paraspinal myositis. Creatinekinase (CK) was found to be 66329 IU/L and a detailed history revealed he was a cocaine user. Paraspinal muscle biopsy confirmed histological features compatible with myositis. Other serological tests were negative, including anti-GBM, ANCA, ANA, Rheumatoid factor, Hep B, Hep C, myositis specific ENA, Treponema pallidum, Borrelia burgdorferi, Rickettsia, Leptospira, EBV and CMV. There was good clinical response to treatment with prednisolone 20 mg OD with an improvement in renal function, CK levels and CRP. He had resumed normal activities and return to work at 6-week follow-up. A detailed social history including substance misuse is important in patients presenting to the ED—especially in cases of severe musculoskeletal pain with no obvious localising features. Drug induced myotoxicity, although rare, can result in symptomatic patients with severe renal failure.

Retained tooth in the nasal cavity: a rare cause of nasal congestion

A 59-year-old man presented with unilateral nasal congestion and discharge. Clinical examination revealed a mass in the floor of the nasal cavity. Sinus CT indicated a retained tooth or a dermoid cyst. It was removed by endoscopic surgery. Histology confirmed the diagnosis of a retained tooth. At follow-up, the patient reported no nasal symptoms. A retained nasal tooth is rare, and the symptoms are variable. It can resemble other diseases such as chronic rhinosinusitis. Surgical removal is recommended to confirm the diagnosis and eliminate symptoms.

'Acute-angled bevel sign to assess donor lenticule orientation in ultra-thin descemet stripping automated endothelial keratoplasty

A 6.5-year-old boy with congenital hereditary endothelial dystrophy underwent clear corneal ultra-thin descemet stripping automated endothelial keratoplasty (DSAEK). After graft insertion, it was difficult to assess graft orientation due to hazy cornea. Intraoperative optical coherence tomography (iOCT) showed a well-attached graft and the bevelled edge of donor lenticule made an acute angle with the overlying stroma. Postoperative anterior segment OCT confirmed the presence of acute-angled bevel sign. A wetlab experiment was performed with experimental corneoscleral tissues to confirm the findings. Donor lenticule was injected in the artificial chamber with stromal-side up as well as stromal side-down. 'Acute-angled bevel sign' was observed on iOCT in the experimental cases with stromal-side up. In inverse graft, the acute-angled bevel was not observed, instead the configuration was obtuse angled. Identifying the 'acute-angled bevel sign' on iOCT confirms correct graft orientation after unfolding and is extremely useful for hazy corneas and ultrathin DSAEK lenticules.

Fulminant thymomatous AMPAR-antibody limbic encephalitis with hypertonic coma, bruxism, an isoelectric electroencephalogram and temporal cortical atrophy, with recovery

Autoimmune encephalitides are a potentially devastating group of treatable disorders with a wide variety of clinical presentations. The most studied autoimmune encephalitis is caused by antibodies to the N-methyl-D-aspartate glutamate receptor. A rarer cause is due to antibodies against the evolutionarily related α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR). The full assortment of electroencephalogram (EEG) and clinical descriptions of the latter are yet to be fully described. A 44-year-old woman with impaired consciousness and subsequent coma characterised by an isoelectric EEG was diagnosed with AMPAR-antibody limbic encephalitis. MRI revealed temporal T2 hyperintensities that improved with immunosuppression, although leaving marked cortical atrophy. Gradual clinical improvement saw the development of aggressive bruxism requiring botulinum toxin injection with eventual meaningful clinical recovery. This case expands the clinical spectrum of AMPAR limbic encephalitis to include aggressive bruxism, and highlights that despite poor clinical and EEG findings at the outset, recovery is still possible.

Ewings sarcoma in maxilla

Ewing sarcoma is a lesion of bone, described in small round cell neoplasm. This tumour resembles primitive neuroectodermal tumour both clinically and histologically. Major difference between these two is that the former arises in the bone and the later in soft tissue. It appears most frequently in males at the age range of of 5–25 years, 80% of which occurs within first two decades of life. Males are more commonly affected than females. Present paper reported with a case report of male patient with 24-year-old showing Ewing's sarcoma of right maxilla.

Retinal and choroidal circulation determined by optical coherence tomography angiography in patient with amyloidosis

A 43-year-old woman who was diagnosed with the cryopyrine-associated periodic syndrome (CAPS) with severe renal failure and heart failure due to amyloid accumulation was examined by swept source optical cohernce tomography (OCT) (SS-OCT; DRI-OCT, Topcon, Tokyo, Japan) and optical coherence tomography angiography (OCTA) (RTVue XR Avanti, Optovue, Fremont, CA). Her best-corrected visual acuity was 20/40 OD and 20/25 OS. A hyporeflective band of about 100 µm thickness was seen just inferior to the retinal pigment epithelium in the cross-sectional SS-OCT images, but the deeper choroidal structures were clearly visible. In the OCTA images, the density of the retinal capillaries in the superficial and deep capillary plexus slabs were reduced, and no signals of the choroidal capillary slab was detected after removing the projection artefacts. The accumulation of amyloid can cause a reduction of both the retinal and choroidal capillary circulations although the circulation in the larger vessels are preserved.

Melanotan-induced priapism: a hard-earned tan

Melanocortin analogues, such as melanotan, are illegally used for artificial tanning. They have also been suggested as possible therapeutic agents in the treatment of erectile dysfunction. This case study presents a patient attending the accident and emergency department, in a tertiary urology centre, with acute priapism after abdominal subcutaneous injection of melanotan. The priapism was diagnosed as 'low-flow' and managed with cavernosal aspiration, irrigation and subsequent intracavernosal injection of phenylephrine. The patient avoided requiring surgical shunting but had not yet recovered erectile function at 4-week follow-up. Acute priapism is an unreported side effect of melanocortin analogue use and this case report presents a patient managed without surgical intervention. Future therapeutic application of these agents will need to take this potential life altering complication into consideration.

The Association of Antibiotic Stewardship With Fluoroquinolone Prescribing in Michigan Hospitals: A Multi-hospital Cohort Study
Abstract
Background
Fluoroquinolones increase the risk of Clostridioides difficile infection and antibiotic resistance. Hospitals often use pre-prescription approval or prospective audit and feedback to target fluoroquinolone prescribing. Whether these strategies impact aggregate fluoroquinolone use is unknown.
Methods
This study is a 48-hospital, retrospective cohort of general-care, medical patients hospitalized with pneumonia or positive urine culture between December 2015–September 2017. Hospitals were surveyed on their use of pre-prescription approval and/or prospective audit and feedback to target fluoroquinolone prescribing during hospitalization (fluoroquinolone stewardship). After controlling for hospital clustering and patient factors, aggregate (inpatient and post-discharge) fluoroquinolone (ciprofloxacin, levofloxacin, moxifloxacin) exposure was compared between hospitals with and without fluoroquinolone stewardship.
Results
There were 11 748 patients (6820 pneumonia; 4928 positive urine culture) included at 48 hospitals. All hospitals responded to the survey: 29.2% (14/48) reported using pre-prescription approval and/or prospective audit and feedback to target fluoroquinolone prescribing. After adjustment, fluoroquinolone stewardship was associated with fewer patients receiving a fluoroquinolone (37.1% vs 48.2%; P = .01) and fewer fluoroquinolone treatment days per 1000 patients (2282 vs 3096 days/1000 patients; P = .01), driven by lower inpatient prescribing. However, most (66.6%) fluoroquinolone treatment days occurred after discharge, and hospitals with fluoroquinolone stewardship had twice as many new fluoroquinolone starts after discharge as hospitals without (15.6% vs 8.4%; P = .003).
Conclusions
Hospital-based stewardship interventions targeting fluoroquinolone prescribing were associated with less fluoroquinolone prescribing during hospitalization, but not at discharge. To limit aggregate fluoroquinolone exposure, stewardship programs should target both inpatient and discharge prescribing.


Prevalence, Predictors, and Successful Treatment Outcomes of Xpert MTB/RIF–identified Rifampicin-resistant Tuberculosis in Post-conflict Eastern Democratic Republic of the Congo, 2012–2017: A Retrospective Province-Wide Cohort Study
Abstract
Background
Multidrug-resistant tuberculosis (MDR-TB) jeopardizes global TB control. The prevalence and predictors of Rifampicin-resistant (RR) TB, a proxy for MDR-TB, and the treatment outcomes with standard and shortened regimens have not been assessed in post-conflict regions, such as the South Kivu province in the eastern Democratic Republic of the Congo (DRC). We aimed to fill this knowledge gap and to inform the DRC National TB Program.
Methods
of adults and children evaluated for pulmonary TB by sputum smear microscopy and Xpert MTB/RIF (Xpert) from February 2012 to June 2017. Multivariable logistic regression, Kaplan–Meier estimates, and multivariable Cox regression were used to assess independent predictors of RR-TB and treatment failure/death.
Results
Of 1535 patients Xpert-positive for TB, 11% had RR-TB. Independent predictors of RR-TB were a positive sputum smear (adjusted odds ratio [aOR] 2.42, 95% confidence interval [CI] 1.63–3.59), retreatment of TB (aOR 4.92, 95% CI 2.31–10.45), and one or more prior TB episodes (aOR 1.77 per episode, 95% CI 1.01–3.10). Over 45% of RR-TB patients had no prior TB history or treatment. The median time from Xpert diagnosis to RR-TB treatment initiation was 12 days (interquartile range 3–60.2). Cures were achieved in 30/36 (83%) and 84/114 (74%) of patients on 9- vs 20/24-month MDR-TB regimens, respectively (P = .06). Predictors of treatment failure/death were the absence of directly observed therapy (DOT; adjusted hazard ratio [aHR] 2.77, 95% CI 1.2–6.66) and any serious adverse drug event (aHR 4.28, 95% CI 1.88–9.71).
Conclusions
Favorable RR-TB cure rates are achievable in this post-conflict setting with a high RR-TB prevalence. An expanded Xpert scale-up; the prompt initiation of shorter, safer, highly effective MDR-TB regimens; and treatment adherence support are critically needed to optimize outcomes.

Glycocalyx Breakdown is Associated with Severe Disease and Fatal Outcome in Plasmodium falciparum Malaria
Abstract
Background
Interactions between the endothelium and infected erythrocytes, microvascular dysfunction and parasite sequestration play major roles in the pathogenesis of severe falciparum malaria. The glycocalyx is a carbohydrate-rich layer lining the endothelium mediating NO production and vascular homeostasis. The role of the glycocalyx in falciparum malaria and the association with disease severity is not known.
Methods
We prospectively enrolled Indonesian inpatients (≥18 years old) with severe (SM) or moderately-severe (MSM) falciparum malaria and healthy controls (HCs). Glycocalyx breakdown products were measured in enrolment samples of urine (glycosaminoglycans; dimethylmethylene blue [GAG-DMMB] and liquid chromatography-tandem mass spectrometry [GAG-MS] assays) and plasma (syndecan-1; ELISA), and related to vascular NO bioavailability (reactive hyperemia-peripheral arterial tonometry).
Results
A total of 129 subjects (SM=43, MSM=57, HC=29) were recruited. Syndecan-1 (µg/ml), GAG-DMMB and GAG-MS (g/mol creatinine) were increased in SM [median (range) 332.4 (85-3-1913), 3.16 (0.04-27.9) and 4.73 (2.02-27.13)] compared to MSM [99.1 (19.9-767.6), 1.28 (0.03-9.3) and 4.44 (1.19-13.87)], and HCs [48.9 (32.3-88.3), 0.11 (0.02-1.9) and 2.55 (0.73-10.19)]; P<0.001. In SM, GAG-DMMB and GAG-MS were increased in non-survivors (n=3) [median (IQR): 6.72 (3.80-27.87) and 12.15 (7.88-17.20)] compared to survivors n=39 [(3.10 (0.46-4.5) and 4.64 (2.02-15.20)]; P=0.03. Glycocalyx degradation was associated with parasite biomass in MSM (r=0.31, P=0.03 [syndecan-1]; r=0.48 [GAG-DMMB] and r=0.43 [GAG-MS], P<0.001), and SM patients (r=0.29, P=0.04, r=0.47; P=0.002 and r=0.33, P=0.04), and inversely associated with endothelial NO bioavailability.
Conclusions
Increased endothelial glycocalyx breakdown is associated with impaired vascular NO, severe disease and fatal outcome in adults with falciparum malaria, likely contributing to pathogenesis.


Impact of rotavirus vaccine introduction in children less than 2 years of age presenting for medical care with diarrhea in rural Matlab, Bangladesh
Abstract
Background
Following the conclusion of a Rotarix vaccine (HRV) cluster-randomized controlled trial (CRT) in Matlab, Bangladesh, HRV was included in Matlab's routine immunization program. We describe the population-level impact of programmatic rotavirus vaccination in Bangladesh in children <2 years of age
Methods
Interrupted time series were used to estimate the impact of HRVintroduction. Diarrheal surveillance collected between 2000 and 2014 within the two service delivery areas (icddr,b service area [ISA] and government service area [GSA]) of the Matlab Health and Demographic Surveillance System administered by icddr,b was used. Age-group specific incidence rates were calculated for both rotavirus-positive (RV+) and rotavirus-negative (RV-) diarrhea of any severity presenting to the hospital. Two models were used to assess impact within each service area: Model 1 used the pre-vaccine time period in all villages (HRV- and control-only) and Model 2 combined the pre-vaccine time period and the CRT time period using outcomes from control-only villages.
Results
Both models demonstrated a downward trend in RV+ diarrheal incidence in the ISA villages during 3.5 years of routine HRV use, though only Model 2 was statistically significant. Significant impact of HRV on RV+ diarrhea incidence in GSA villages was not observed in either model. Differences in population-level impact between the two delivery areas may be due to varied rotavirus vaccine coverage and presentation rate to the hospital.
Conclusions
This study provides initial evidence of the population-level impact of rotavirus vaccines in children <2 years of age in Matlab, Bangladesh. Further studies of rotavirus vaccine impact after nationwide introduction in Bangladesh are needed.


Transmission-blocking effects of primaquine and methylene blue suggest P. falciparum gametocyte sterilisation rather than effects on sex ratio
Abstract
Gametocyte density and sex-ratio can predict the proportion of mosquitoes that become infected after feeding on blood of patients receiving non-gametocytocidal drugs. Because primaquine and methylene blue sterilize gametocytes before affecting their density and sex-ratio, mosquito feeding experiments are required to demonstrate their early transmission-blocking effects.


Principal Controversies in Vaccine Safety in the United States
Abstract
Concerns about vaccine safety can lead to decreased acceptance of vaccines and resurgence of vaccine-preventable diseases. We summarize the key evidence on some of the main current vaccine safety controversies in the United States, including: 1) MMR vaccine and autism; 2) thimerosal, a mercury-based vaccine preservative, and the risk of neurodevelopmental disorders; 3) vaccine-induced Guillain-Barré Syndrome (GBS); 4) vaccine-induced autoimmune diseases; 5) safety of HPV vaccine; 6) aluminum adjuvant-induced autoimmune diseases and other disorders; and 7) too many vaccines given early in life predisposing children to health and developmental problems. A possible small increased risk of GBS following influenza vaccination has been identified, but the magnitude of the increase is less than the risk of GBS following influenza infection. Otherwise, the biological and epidemiologic evidence does not support any of the reviewed vaccine safety concerns.

Birth Cohort Studies Assessing Norovirus Infection and Immunity in Young Children: A Review
Abstract
Globally, noroviruses are among the foremost causes of acute diarrheal disease, yet there are many unanswered questions on norovirus immunity, particularly following natural infection in young children during the first 2 years of life when the disease burden is highest. We conducted a literature review on birth cohort studies assessing norovirus infections in children from birth to early childhood. Data on infection, immunity, and risk factors are summarized from 10 community-based birth cohort studies conducted in low- and middle-income countries. Up to 90% of children experienced atleast one norovirus infection and up to 70% experienced norovirus-associated diarrhea, most often affecting children 6 months of age and older. Data from these studies help to fill critical knowledge gaps for vaccine development, yet study design and methodological differences limit comparison between studies, particularly for immunity and risk factors for disease. Considerations for conducting future birth cohort studies on norovirus are discussed.

Cost-effectiveness and Cost-utility of the Adherence Improving Self-management Strategy in Human Immunodeficiency Virus Care: A Trial-based Economic Evaluation
Abstract
Background
Several promising human immunodeficiency virus (HIV) treatment adherence interventions have been identified, but data about their cost-effectiveness are lacking. This study examines the trial-based cost-effectiveness and cost-utility of the proven-effective Adherence Improving Self-Management Strategy (AIMS), from a societal perspective, with a 15-month time horizon.
Methods
Treatment-naive and treatment-experienced patients at risk for viral rebound were randomized to treatment as usual (TAU) or AIMS in a multicenter randomized controlled trial in the Netherlands. AIMS is a nurse-led, 1-on-1 self-management intervention incorporating feedback from electronic medication monitors, delivered during routine clinical visits. Main outcomes were costs per reduction in log10 viral load, treatment failure (2 consecutive detectable viral loads), and quality-adjusted life-years (QALYs).
Results
Two hundred twenty-three patients were randomized. From a societal perspective, AIMS was slightly more expensive than TAU but also more effective, resulting in an incremental cost-effectiveness ratio (ICER) of €549 per reduction in log10 viral load and €1659 per percentage decrease in treatment failure. In terms of QALYs, AIMS resulted in higher costs but more QALYs compared to TAU, which resulted in an ICER of €27759 per QALY gained. From a healthcare perspective, AIMS dominated TAU. Additional sensitivity analyses addressing key limitations of the base case analyses also suggested that AIMS dominates TAU.
Conclusions
Base case analyses suggests that over a period of 15 months, AIMS may be costlier, but also more effective than TAU. All additional analyses suggest that AIMS is cheaper and more effective than TAU. This trial-based economic evaluation confirms and complements a model-based economic evaluation with a lifetime horizon showing that AIMS is cost-effective.

Doravirine/Lamivudine/Tenofovir Disoproxil Fumarate is Non-inferior to Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate in Treatment-naive Adults With Human Immunodeficiency Virus–1 Infection: Week 48 Results of the DRIVE-AHEAD Trial
Abstract
Background
Doravirine (DOR), a novel non-nucleoside reverse-transcriptase inhibitor (NNRTI), is active against wild-type Human Immunodeficiency Virus (HIV)-1 and the most common NNRTI-resistant variants, and has a favorable and unique in vitro resistance profile.
Methods
DRIVE-AHEAD is a phase 3, double-blind, non-inferiority trial. Antiretroviral treatment–naive adults with ≥1000 HIV-1 RNA copies/mL were randomized (1:1) to once-daily, fixed-dose DOR at 100 mg, lamivudine at 300 mg, and tenofovir disoproxil fumarate (TDF) at 300 mg (DOR/3TC/TDF) or to efavirenz at 600 mg, emtricitabine at 200 mg, and TDF at 300 mg (EFV/FTC/TDF) for 96 weeks. The primary efficacy endpoint was the proportion of participants with <50 HIV-1 RNA copies/mL at week 48 (Food and Drug Administration snapshot approach; non-inferiority margin 10%).
Results
Of the 734 participants randomized, 728 were treated (364 per group) and included in the analyses. At week 48, 84.3% (307/364) of DOR/3TC/TDF recipients and 80.8% (294/364) of EFV/FTC/TDF recipients achieved <50 HIV-1 RNA copies/mL (difference 3.5%, 95% CI, -2.0, 9.0). DOR/3TC/TDF recipients had significantly lower rates of dizziness (8.8% vs 37.1%), sleep disorders/disturbances (12.1% vs 25.2%), and altered sensorium (4.4% vs 8.2%) than EFV/FTC/TDF recipients. Mean changes in fasting low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) (-3.83 vs +13.26 mg/dL) were significantly different between DOR/3TC/TDF and EFV/FTC/TDF (−1.6 vs +8.7 mg/dL and −3.8 vs +13.3 mg/dL, respectively).
Conclusions
In HIV-1 treatment-naive adults, DOR/3TC/TDF demonstrated non-inferior efficacy to EFV/FTC/TDF at week 48 and was well tolerated, with significantly fewer neuropsychiatric events and minimal changes in LDL-C and non–HDL-C compared with EFV/FTC/TDF.

Concurrent Seroprevalence of Antibodies to Toxoplasma gondii and Toxocara Species in the United States, 2011–2014
To the Editor—We report supplemental findings incorporating Toxoplasma gondii serology results from our study of risk factors for Toxocara seropositivity in the United States [1] using stored serum samples collected from the National Health and Nutrition Examination Survey (NHANES), 2011–2014. Whereas T. gondii is a protozoan parasite and Toxocara is an intestinal nematode, both share ingestion of contaminated soil as means of exposure in humans. Both parasites can contaminate soil when environmentally resistant T. gondii oocysts or Toxocara cati eggs are shed in the feces of infected cats [23].





Hepatitis C Guidance 2018 Update: AASLD-IDSA Recommendations for Testing, Managing, and Treating Hepatitis C Virus Infection
Abstract
Recognizing the importance of timely guidance regarding the rapidly evolving field of hepatitis C management, the American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) developed a web-based process for the expeditious formulation and dissemination of evidence-based recommendations. Launched in 2014, the hepatitis C virus (HCV) guidance website undergoes periodic updates as necessitated by availability of new therapeutic agents and/or research data. A major update was released electronically in September 2017, prompted primarily by approval of new direct-acting antiviral agents and expansion of the guidance's scope. This update summarizes the latest release of the HCV guidance and focuses on new or amended recommendations since the previous September 2015 print publication. The recommendations herein were developed by volunteer hepatology and infectious disease experts representing AASLD and IDSA and have been peer reviewed and approved by each society's governing board.


Functional Improvements Utilizing the Short Physical Performance Battery (SPPB) in the Elderly after Epidural Steroid Injections

Abstract

Purpose of Review

The treatment of debilitating pain and loss of function secondary to lumbar stenosis is in high demand with the aging patient population. Options, including epidural steroid injections (ESIs) and medication therapy, are limited and it is unclear if they provide any functional improvements. In this prospective study, we evaluate functional outcomes in older adults with symptomatic lumbar stenosis treated with ESIs compared to those managed with medications by introducing the Short Physical Performance Battery (SPPB). Our study was IRB-approved and included 16 patients, 68 to 83 years old, with symptomatic back and radicular leg pain secondary to lumbar stenosis. Patients could elect to undergo a lumbar ESI (n = 11) or be treated via medication management (n = 5). Numeric pain score, SPPB score, and adverse events were measured and compared at baseline and a 1-month follow-up visit.

Recent Findings

Statistically significant improvements were observed from baseline compared to the 1-month follow-up for total SPPB score in the injection group. Similar improvements in the injection group were observed for pain scores and the SPPB subcomponents such as the 4-m walk test, chair stand time, and balance score. Comparatively, no statistically significant improvements were observed in the medication group.

Summary

Lumbar ESIs improved objective physical capacity parameters and pain scores in elderly patients with symptomatic lumbar stenosis compared to medication management. In addition, the SPPB is an easy-to-use tool to measure changes in physical function in older adults and could easily be integrated into an outpatient pain clinic.

Perioperative Considerations in the Management of Anticoagulation Therapy for Patients Undergoing Surgery

Abstract

Purpose of Review

As ambulatory surgery has become increasingly more common, the appropriate management of anticoagulation therapy in patients undergoing invasive procedures has become progressively more relevant to healthcare professionals. The purpose of this literature review is to provide an overview of current common anaticoagulants and their pharmacological properties and to evaluate recent relevant literature and bridging therapy and provide recommendations on risk-guided therapy.

Recent Findings

With the development of new drugs and the advancing study and practice of anticoagulation use, clinicians must keep up-to-date on the optimal management of patients requiring anticoagulation. NOACs and warfarin continue to be the mainstays of treatment, with varying timelines regarding when to hold administration of the different agents within the perioperative period.

Summary

There are numerous factors that are considered in patients with multiple comorbidities including the risk for stroke on long-term anticoagulation and risk for thromboembolism, particularly in the perioperative setting when certain medication regimens may be altered and/or briefly held. There is ongoing investigation whether certain NOACs have more efficacy or greater safety profiles, depending on the degree of surgical intervention.

External root resorption in maxillary and mandibular second molars associated with impacted third molars: a cone-beam computed tomographic study

Abstract

Objective

To separately investigate the prevalence and risk factors of external root resorption (ERR) in maxillary and mandibular second molars (M2s) adjacent to impacted third molars (M3s).

Materials and methods

CBCT scans involving 184 maxillary and 323 mandibular impacted M3s were included. Age, gender, the impaction status of M3, the presence, severity, and location of ERR in M2 were assessed. Risk factors were identified by multivariate logistic regression analyses.

Results

The prevalence of ERR was 32.6% in maxillary and 52.9% in mandibular M2s (P < 0.001). Mesio-angulated and deeply impacted M3s were identified as risk factors for both ERR in maxillary and mandibular M2s (P < 0.05). Besides, age over 25 increased the risk of ERR in maxillary M2s (P < 0.05). ERR in maxillary M2s was overall more severe than that in mandibular M2s (P < 0.001). For maxillary M2s, ERR mostly occurred at the apical third, while the mandibular M2s ERR was most frequently detected at the cervical third.

Conclusions

ERR occurring in M2s adjacent to impacted M3s is common, especially in mandibular M2s. ERR in maxillary M2s cannot be neglected because of its relatively high severity. Mesial angulation and impaction depth of M3 are significantly associated with ERR in M2s. For ERR in maxillary M2s, age is another predictive parameter.

Clinical relevance

Considering the presence of ERR is associated with M3s' impaction, watchful monitoring or prophylactic removal of impacted M3s should be deliberated especially for the patients over 25 years and with mesially inclined and deeply positioned M3s.

Expression of Wnt‐1 and TSLC1 in condyloma acuminatum

Summary

Background

Despite its high contagiousness, high recurrence rate and potential for malignant transformation, effective treatments for condyloma acuminatum (CA) have not yet been developed. Accordingly, it is necessary to clarify the mechanisms underlying CA development.

Aim

To investigate the expression and significance of the proteins Wnt‐1 and TSLC1 in patients with CA and in normal foreskin controls.

Methods

Wnt‐1 and TSLC1 were assessed by immunohistochemistry in 45 patients with CA.

Results

Positive expression rates of Wnt‐1 and TSLC1 were 82.22% (37/45) and 37.78% (17/45), respectively, in CA tissues, and 29.17% (7/24) and 91.67% (22/24), respectively, in normal foreskin controls. Wnt‐1 expression intensity in CA was markedly higher (positive to strongly positive) than that in normal controls (negative to weakly positive), whereas TSLC1 expression intensity ranged from weakly positive to positive in CA, and nearly strongly positive in the normal control group. The differences in the positive expression rate and expression intensity of Wnt‐1 and TSLC1 between the two groups were statistically significant (< 0.05). In addition, Wnt‐1 and TSLC1 were negatively correlated. (r = −0.336, P < 0.05).

Conclusions

Overexpression of Wnt‐1 and low expression of TSLC1 may be associated with the growth of CA. These findings may provide a basis for the development of therapies to prevent recurrence or malignant transformation of CA.

Nail cosmetics: a dermatological perspective

Summary

Nail cosmetics are used by millions worldwide and the variety of products available is expanding. They are relatively safe, but complications can occur, and patients experiencing complications may present to dermatologists. The physical processes can cause nail thinning and onycholysis, poor technique can promote infection, and consumers may develop allergic contact dermatitis. Ultraviolet nail lamps are widely used for curing gel nails, but their use is unregulated and they are readily accessible in salons or for home use. There is concern about potential carcinogenesis; however, the risk is negligible and can be further reduced with the use of sunscreen. Despite the potential complications, nail cosmetics may be a useful adjunct in treating nail disorders. Familiarity with the procedures will enable the dermatologist to recognize problems and advise on safe use.

The efficacy of combined diluted calcium hydroxylapatite‐based filler and an energy‐based device in the treatment of facial atrophic acne scars

Abstract

Background and Objectives

Treatment options for atrophic acne scars include the use of various energy‐based devices (EBDs) and dermal fillers.

Aim

To evaluate the level of improvement and safety of four treatment modalities for atrophic acne scars employed in our center.

Methods

We reviewed the medical records of all acne scar patients treated between 2013‐2016 with one of four treatment modalities: ablative fractional CO2 laser (FACL), the radiofrequency (RF) bipolar device, the 1540 nm non‐ablative fractional laser (NAFL), and the injection of diluted calcium hydroxylapatite (CaHA). The EBDs were used as monotherapy or in combination with diluted CaHA. Two non‐involved dermatologists and the patients evaluated the aesthetic improvement achieved following the various modalities. The patients also rated their satisfaction, numbered the days of post‐treatment downtime, and reported any adverse effects.

Results

In total, 352 patients (mean age 28.7±8.7, 65.6% females) were treated for acne scars. The integrated mean dermatologists' and patients' GAS scores were the highest for the patients treated with the combined FACL‐CaHA modality at separate sessions (P < 0.001). Patients treated with FACL reported more side effects and longer downtime and duration of erythema.

Conclusions

The combination of a diluted CaHA‐based filler injection followed by fractional ablative CO2 laser in separate treatment sessions yielded better aesthetic improvement compared to the other tested modalities.

Precision Medicine in Rhinosinusitis

Abstract

Purpose of Review

Our scope is the presentation of research and clinical progresses in relation to precision medicine that are expected to alter our clinical practice in relation to chronic rhinosinusitis (CRS). Current knowledge on phenotypes and endotypes, biomarkers, and clinical markers for diagnosis, medical and surgical therapy, and prognosis is presented as well as the role of precision medicine in United Airway Disease and SCUAD (severe-uncontrolled chronic upper airway inflammation).

Recent Findings

Current technological progresses, mostly in relation to molecular biology and information technology, have permitted more detailed pathophysiological assessments and multidimensional approaches in airways diseases. Based on the concept of united airways diseases, new classification schemes, called endotypes, have been proposed for CRS. In addition, novel biological treatments that have been introduced for the treatment of asthma show great promise as well for severe uncontrolled cases of CRS with nasal polyps. Central to this approach are new biomarkers that are being examined in relation to complex bio-clinical traits of CRS.

Summary

As this narrative review of the aforementioned precision medicine initiatives in relation to CRS advances, a modification of current practice is expected not only for severe chronic upper airways diseases in tertiary centers but also for milder and more common cases that are being encountered in the community.

Multimorbidities of Pediatric Allergic Rhinitis

Abstract

Purpose of Review

Most children and adolescents with allergic rhinitis (AR) present extra-nasal multimorbid conditions, including conjunctivitis, asthma, atopic dermatitis, rhinosinusitis, or seromucous otitis. Additionally, they may present nasal obstructive disorders, such as septal deformity, turbinate enlargement, and adenoidal hyperplasia, which worsen nasal symptoms, especially nasal obstruction. This is a narrative review on the current state of the concomitant presence of AR and one or more multimorbidities.

Recent Findings

The presence of AR and one or more accompanying multimorbidities is associated to a higher severity and duration of the disease, a negative impact on quality of life, with worse control and lack of improvement with medical treatment. Therefore, AR needs to be managed with a multidisciplinary collaborative approach.

Summary

Pediatric AR needs to be considered in the context of a systemic disease, which requires a coordinated therapeutic strategy.

Pediatric Drug Hypersensitivity

Abstract

Purpose of Review

Pediatric drug hypersensitivity is a rapidly evolving field. The purpose of this paper is to review the current state of pediatric drug hypersensitivity and highlight new developments in diagnosis and management.

Recent Findings

This paper will discuss the safety and use of risk stratification to proceed directly to oral challenge without prior skin testing for β-lactam reactions. We review unique aspects of pediatric drug challenges and desensitizations.

Summary

It is important to accurately diagnose pediatric drug hypersensitivity reactions through a detailed history, physical examination, and available diagnostic testing. Understanding of the underlying mechanism leads to appropriate classification which is necessary to direct management. The decision to perform drug challenge, desensitization, or recommend avoidance of a medication can have a significant impact on a patient's treatment. Utilization of weight-based dose and infusion rate adjustments for current drug challenge and desensitization protocols optimize success.

Surgery is not the only determinant of an outcome in patients with hypopharyngeal carcinoma

Abstract

Background

The aim of this study was to evaluate the outcomes in patients treated for hypopharyngeal carcinoma in a single‐center and the importance of considering how patient factors influence outcomes.

Methods

A retrospective review was conducted on patients who were seen at the Prince of Wales Hospital from 1968 to 2015. Kaplan‐Meier and Cox regression analyses were performed for each patient and treatment factor to investigate outcomes of local control, cancer‐specific survival (CSS), and ultimate local control.

Results

Three hundred thirty patients were analyzed. Significant multivariate predictors for improved local control and CSS were fitness for surgery, cancer operability, surgery with adjuvant radiotherapy, no treatment interruptions (P < .05). Five‐year local control (84%), CSS (50%), and ultimate local control (84%) rates were significantly higher in patients treated surgically with adjuvant radiotherapy, compared to single modality treatment (P < .05).

Conclusion

Patient factors influence the outcomes experienced by patients with hypopharyngeal carcinoma.

Dupilumab provides important clinical benefits to patients with atopic dermatitis who do not achieve clear or almost clear skin according to the Investigator's Global Assessment: a pooled analysis of data from 2 phase III trials

Summary

Background

In the US, an Investigator's Global Assessment (IGA) score of ≤ 1 (clear/almost clear skin) has been the regulatory outcome standard measure for registration clinical trials in atopic dermatitis (AD), including those supporting the recent approval of dupilumab.

Objective

To evaluate the treatment effect of dupilumab in patients with IGA>1 at the end of treatment, using other validated outcome measures for AD signs, symptoms and quality of life.

Methods

LIBERTY AD SOLO 1 and 2 were two 16‐week, randomized, double‐blind trials enrolling adult patients with moderate‐to‐severe AD (IGA≥3) inadequately controlled with topical treatment. We performed a post‐hoc analysis in patients receiving dupilumab 300 mg every 2 weeks (q2w) or placebo. Outcome measures in patients with IGA>1 included Eczema Area and Severity Index (EASI), pruritus Numerical Rating Scale (NRS), affected Body Surface Area (BSA), Patient‐Oriented Eczema Measure (POEM), and Dermatology Life Quality Index (DLQI).

Results

At Week 16, 278/449 dupilumab q2w‐treated patients (median age 36·0 years) and 396/443 placebo‐treated patients had IGA>1. Among patients with IGA>1 at Week 16, dupilumab significantly improved several outcome measures compared with placebo: EASI (–48·9% vs. –11·3%, P<0·001), pruritus NRS (–35·2% vs. –9·1%, P < 0·001), BSA affected (–23·1% vs. –4·5%, P<0·001), POEM score ≥ 4‐point improvement (57·4% vs. 21·0%, P<0·001), and DLQI score ≥ 4‐point improvement (59·3% vs. 24·4%, P<0·001).

Conclusions

In patients with IGA>1 at Week 16, dupilumab induced statistically significant benefits in multiple validated outcome measures versus placebo. The IGA≤1 endpoint significantly underestimates clinically relevant dupilumab treatment effects.

Chemoradiotherapy could improve overall survival of patients with stage IV cutaneous squamous cell carcinoma: analysis of 34 cases

Abstract

Cutaneous squamous cell carcinoma (cSCC) is the second most common non‐melanoma skin cancer, comprising approximately 20% of all skin malignancies1. The prognoses of patients with unresectable disease, such as locally advanced tumour or distant metastases, are known to be relatively poor due to lack of effective standardized systemic therapies2,3. When surgery is not feasible, non‐surgical approaches such as chemotherapy, radiation therapy (RT), and chemoradiotherapy (CRT; chemotherapy with radiation), are considered as alternative treatments2.

Serum cytokeratin 19 fragment 21‐1 and carcinoembryonic antigen combination assay as a biomarker of tumour progression and treatment response in extramammary Paget's disease

Summary

Background

Extramammary Paget's disease (EMPD) is a rare intraepithelial adenocarcinoma affecting the genitals and axillary regions. As metastasis of these tumours is itself rare, solid disease management strategies have not been established. Serum carcinoembryonic antigen (CEA) and cytokeratin 19 fragment 21‐1 (CYFRA 21‐1) levels have been identified as candidate biomarkers for tumour progression in EMPD; however, neither the accuracy of, nor correlation between, these markers have been examined in EMPD patients.

Methods

Serum CEA and CYFRA 21‐1 levels were examined in 30 EMPD patients treated at Keio University Hospital, and compared against clinical information retrospectively. Both assays were performed at the time of diagnosis, during the postoperative observation period, and following systemic treatment in those with confirmed metastasis. Serum levels were then correlated with tumour progression status and treatment responses.

Results

Normal levels for both assays were observed in all 11 primary localised patients (100%). In metastatic patients, the CEA positivity rate was 78·9% (15/19 patients) and 63·1% (11/19 patients) for CYFRA 21‐1. Changes in CEA and CYFRA 21‐1 levels were statistically independent; however, using a combined view, elevated levels of either marker improved the positivity rate to 94·8% (18/19 patients). Use of both markers also correlated well with the treatment responses.

Conclusions

The combination of CEA and CYFRA 21‐1 is useful for predicting metastasis and treatment response in EMPD patients, especially in those who only have elevation of a single marker.

Spindle cell liposarcoma with a TRIO-TERT fusion transcript

Abstract

Conventional well-differentiated, dedifferentiated, and myxoid liposarcomas have long been known to harbor numerous typical genetic alterations that allow for diagnosis of these tumors. These include MDM2 and CDK4 amplification in well-differentiated and dedifferentiated liposarcomas as well as FUS-DDIT3 rearrangements in myxoid liposarcoma. More recently, in-frame TRIO-TERT fusion genes have been described in a subset of non-translocation-related sarcomas including myxofibrosarcoma, dedifferentiated liposarcoma, undifferentiated pleomorphic sarcoma, pleomorphic rhabdomyosarcoma, and leiomyosarcoma. These genetic rearrangements lead to TERT mRNA expression levels hundreds of times higher than normal, causing increased telomerase activation in these tumors. Herein, we describe an unusual case of a liposarcoma with spindle cell features and a TRIO-TERT fusion transcript identified through next-generation sequencing.

Pretreatment Hearing Level—Another Prognostic Factor in Sudden Sensorineural Hearing Loss—Reply

In Reply We thank Dr Wu and colleagues for their interest and comments on our research. Various factors may affect hearing recovery after SSHL, such as age, degree of hearing loss, type of hearing loss, interval from onset of symptoms to treatment, tinnitus, type 2 diabetes, cardiovascular disease, and the presence of vertigo. We were unable to include the hearing level at onset into our analyses owing to the lack of corresponding data in the included studies. Moreover, only 1 of the included studies assessed the possible association between the presence of vertigo and hearing recovery in patients with severe sudden sensorineural hearing loss (≥60 dB). We also think that the opinion by Dr Wu et al that the presence of vertigo is significantly correlated only with hearing recovery in the group with profound SSHL may have implications for the understanding of the mechanisms of SSHL with vertigo, but we were unable to retrieve the raw data. At present, the pathogenesis, clinical manifestations, optimal treatments, and prognostic factors of SSHL are not clear. We are in the process of validating the occurrence of vertigo and its possible role in SSHL. A complete analysis of this role will require more unbiased studies with prospectively gathered data in a large sample size to estimate the precise association of vertigo with the clinical manifestation and prognosis of SSHL.

Silent Aspiration in Laryngomalacia?

Laryngomalacia is the most common laryngeal anomaly in infants, with a presentation of inspiratory stridor being nearly ubiquitous. In addition, young children with laryngomalacia can demonstrate feeding difficulty, dysphagia, aspiration, failure to thrive, apnea, cyanosis, and/or obstructive sleep apnea. Managing the balancing act between sucking, breathing, and swallowing is anticipated to carry additional challenge in infants with airway abnormalities, potentially leading to dysphagia, aspiration, and feeding difficulties. Somewhat unsurprisingly, infants with laryngomalacia may cough and choke during feeding, take their feeds slowly, or develop a worsening of their stridor during feeding. The association between laryngomalacia and feeding disorders is further strengthened by a biological gradient relationship, with more severe laryngomalacia cases shown to be more likely to have symptoms of feeding difficulty. In addition to dyscoordination, other proposed causes for feeding challenges in patients with laryngomalacia include decreased laryngeal sensation secondary to acid reflux and an alteration in the sensorimotor integrative function of the larynx. The association between acid reflux and laryngomalacia is well established, although evidence is lacking for causality or even direction of causality (ie, which is the chicken and which is the egg). Sensorimotor impairment in laryngomalacia is evidenced by the finding that children with laryngomalacia have higher rates of neurologic abnormalities such as hypotonia, central apneas and developmental disorders, and histopathologic nerve differences in their laryngeal mucosa.

CME article part 1: Visual perception, cognition and error in dermatologic diagnosis

Dermatologic diagnosis relies on vision primarily and auditory and verbal input secondarily. Accurate dermatologic diagnosis is predicated on 1) seeing and perceiving a skin finding, 2) categorizing and naming the finding correctly, and 3) comparing the visual data and data obtained from the totality of the clinical encounter (i.e., from other sensory modalities) with one's working mental database of dermatologic diagnoses. The baseline assumption – which is false - is that a dermatologist is expert at each of the aforementioned steps and transitions sequentially between them seamlessly in an error-free fashion.

Visual perception, cognition and error in dermatologic diagnosis, Part 2 of 2

Diagnostic error in dermatology is a large practice gap that has received little attention. Diagnosis in dermatology relies heavily on a heuristic approach responsible for our perception of clinical findings. In order to improve our diagnostic accuracy, a better understanding of the strengths and limitations of heuristics (cognitive short cuts) used in dermatology is essential. Numerous methods have been proposed to improve diagnostic accuracy, including brain training, reducing cognitive load, getting feedback and second opinions.

Carious lesion activity assessment in clinical practice: a systematic review

Abstract

Objectives

The objective of the manuscript is to systematically review the different techniques developed for activity assessment of coronal carious lesions (AACCL) in clinical settings.

Materials and methods

A search of PubMed identified original articles in English reporting on the different concepts/tools for AACCL in clinical settings and, when available, data related to their in vivo/in situ validation in terms of sensitivity, specificity, inter- and intra-examiner reproducibilities, area under the receiving operating curve, positive predictive value, negative predictive value, and relative risk of lesion progression.

Results

The present review included 25 articles. Four groups of techniques are available (1) systems based on combinations of visual and tactile criteria; devices based on (2) pH assessment, (3) fluorescence, or (4) bioluminescence. The most studied systems are those based on combinations of visual and tactile parameters when bioluminescence suffers from the lack of in vivo evaluation. Validation studies showed a wide disparity among protocols in terms of populations, dentitions, teeth surfaces, study design, the gold standard, and validation criteria.

Conclusion

There is a need for definition and harmonization of standards for activity assessment-related concepts/tools, as well as further investigations for in vivo validation of newly developed tools.

Clinical relevance

Carious lesion activity is an important component to be taken into account when making decisions as to appropriate clinical caries management. The development and use of validated techniques which are easy to use in everyday dental practice are important.

Head and Neck Cancer Compared With Other Cancers—Does the Great Equalizer Equalize Equally?

When Andrew Lo, PhD, of the Massachusetts Institute of Technology Sloan School of Management stated, "Cancer is the great equalizer. Everyone is affected by it either themselves or through loved ones," we might infer that the experience of this very human tragedy would cut through factors that can be divisive, such as race, sex, educational status, and socioeconomic status. The implication is that before cancer we are all equal, regardless of such factors. However, the recent work by Massa et al indicates that this may not be the case.

Observations, knowledge, and attitude towards treatment options in patients with dry mouth: a survey among German dentists

Abstract

Objectives

The aim of this study was to investigate the attitude, observations, and knowledge of German dentists regarding the management of dry mouth.

Materials and methods

A questionnaire including queries about attitudes, observations, and treatment options in patients with dry mouth was developed and sent to all 1251 dentist members of a regional German dental association.

Results

An overall total of 284 returned questionnaires were included in the analyses, which relates to a response rate of 22.7%. Dentists infrequently encountered dry mouth in their clinical routine, yet were well aware that patients suffer from the symptoms of dry mouth; for affected patients, the majority of participating dentists provided specific dental prophylaxis measures. Drug side effects, neoplasia, and psychological disorders were regarded as the primary etiological factors for dry mouth, and caries, increased plaque formation, and rhagades as the most frequently observed clinical symptoms. While the majority of participating dentists was of the opinion that saliva substitutes are useful treatment options in patients with dry mouth, only few frequently recommended their use. Mechanical and gustatory stimulation of salivary flow as well as the advice to rinse with water were the most frequently pursued treatment options.

Conclusions

Despite the high prevalence of dry mouth identified in epidemiological studies, it appears to be an infrequent observation in clinical routine.

Clinical relevance

Pre- and postgraduate education should sensitize dentists for dry mouth and its treatment options.
