Evaluation of Mucociliary Activity in Maxillary Antra in Patients with Squamous Cell Carcinoma of Buccal Mucosa Undergoing Post Operative Radiotherapy

Abstract

A prospective longitudinal observational study was conducted on 24 patients of histopathologically confirmed squamous cell carcinoma of buccal mucosa upon whom bilateral 'middle meatal antrostomy was performed during the same sitting as the tumour resection with the main aim to assess the maxillary mucociliary clearance, pre-, during and post-irradiation; and compare the findings with the non-irradiated side in the same patient to avoid any confounding factors. All patients underwent methylene blue dye clearance and saccharine clearance tests before the commencement of radiation therapy, weekly during irradiation and again at first and sixth month of completion of irradiation. Pre-radiation there was statistically no difference (P > 0.05) in clearance times between both sides. But, there was a significant (P < 0.001) increase in saccharin and methylene blue clearance times on the irradiated side in comparison to contralateral non-irradiated side, during and post-radiation. It is concluded that external beam radiotherapy for oral cancers significantly affect ciliary activity in the adjacent maxillary antrum and has no effect on the opposite side. Recovery in mucociliary activity was not seen even after 6 months after radiation therapy.

Sinonasal Metastatic Renal Cell Carcinoma: A Report of Two Cases with Varied Presentation and a Review of Literature

Abstract

Renal cell carcinoma is usually slow growing with delayed vague symptoms and may not be detected until an advanced stage. In only 9% of the cases the classical triad of "haematuria, costovertebral pain and abdominal mass" is seen. Less commonly, sinonasal metastasis may also be the presenting feature of RCC. So, in any case of sinonasal mass, possibility of metastasis from renal malignancy should be considered. Sinonasal metastasis from renal malignancy can occur even several years after the primary is treated with nephrectomy. In sinonasal region maxillary sinus is the most commonly affected. Isolated metastasis to the nose is extremely rare. Malignancies from various other sites of the body can also metastasize to sinonasal region. Epistaxis is the most common symptom. This is because of vascular stroma of the metastatic deposit. A 45 year old male with history of right nephrectomy 1 year back presented with intractable epistaxis. A 66 year old male presented with profuse epistaxis without any history of previous malignancies. Both the cases were evaluated resulting to the diagnosis of sinonasal metastasis from Renal Cell carcinoma. In the first case, metastasis occurred 1 year post surgery whereas in second case sinonasal metastasis was the presenting feature of Renal Cell carcinoma. Epistaxis is the most common symptom. This is because of vascular stroma of this metastatic deposit. In renal cancer, symptoms of metastasis often precede the symptoms of primary tumor.

Facial nerve decompression

Purpose of review Facial nerve paralysis is a debilitating condition. Bell's palsy and temporal bone trauma are common causes of acute facial palsy, with recurrent idiopathic paralysis and Melkersson–Rosenthal syndrome accounting for a smaller subset of cases. Properly selected patients may benefit from facial nerve decompression. This article will review the relevant literature on facial nerve decompression. Recent findings The middle cranial fossa approach provides access to the primary site of lesion in Bell's palsy while preserving hearing. Patients with complete facial paralysis secondary to Bell's palsy or temporal bone trauma, more than 90% degeneration on electroneurography testing, and absent voluntary electromyography within 14 days of onset may benefit from facial nerve decompression. Facial nerve decompression may prevent future occurrences of recurrent forms of facial nerve paralysis. The return of facial nerve function following decompression will occur over weeks to months. Summary Appropriately selected patients with facial paralysis secondary to Bell's palsy or temporal bone trauma may benefit from facial nerve decompression. Patients should be counseled regarding the risks of decompression and that the return of maximal facial nerve function may be delayed up to 12 months. Correspondence to Marlan R.

Acute and chronic phagocyte determinants of cardiac allograft vasculopathy

Abstract

Post-transplant immunosuppression has reduced the incidence of T cell-mediated acute rejection, yet long-term cardiac graft survival rates remain a challenge. An important determinant of chronic solid organ allograft complication is accelerated vascular disease of the transplanted graft. In the case of cardiac allograft vasculopathy (CAV), the precise cellular etiology remains inadequately understood; however, histologic evidence hints at the accumulation and activation of innate phagocytes as a causal contributing factor. This includes monocytes, macrophages, and immature dendritic cell subsets. In addition to crosstalk with adaptive T and B immune cells, myeloid phagocytes secrete paracrine signals that directly activate fibroblasts and vascular smooth muscle cells, both of which contribute to fibrous intimal thickening. Though maladaptive phagocyte functions may promote CAV, directed modulation of myeloid cell function, at the molecular level, holds promise for tolerance and prolonged cardiac graft function.

Role of industry funding in academic dermatology

Since 2003, the NIH Budget for research grants has diminished. As a result more academic physicians are turning to pharmaceutical and medical device companies for funding. The aim of this project was to examine the relationship between private industry funding in dermatology and the relative scholarly impact created by investigators who received this funding. The objective of this study was to compare the impact of the h-index, a weighted index of academic productivity, to the amount of industry research funding received by colleagues.

The evolution of confocal microscopy in dermatology

Reflectance confocal microscopy (RCM) is a diagnostic imaging tool used to visualize the skin in vivo at the bedside with accuracy that parallels histology. For tissue examination, RCM uses lasers to produce optical sections by illuminating the specimen and by scanning focused beams of light across the tissue. The principle of point illumination in confocal microscopy was first proposed by Marvin Minsky in 1955, and serves as the basis for all subsequent developments for this technology. In the 1970s, lasers were introduced, and shortly after that photomicrographs of histologically recognizable cells were published.

Systemic lupus erythematosus with toxic epidermal necrolysis–like lesions: An infrequent variant of acute cutaneous erythematous lupus

Introduction: Skin manifestations in systemic lupus erythematosus (SLE) are very heterogeneous. Toxic epidermal necrolysis (TEN)–like lesions are an infrequent clinical presentation of SLE that are included as diagnostic criteria and a variant of acute cutaneous lupus. It presents with photodistributed exanthema and minimal mucositis and the onset of the rash is insidious. Differential diagnosis between "TEN-like" LE and classic TEN, could be difficult especially when LE has not been previously diagnosed.

Steroid-assisted drug delivery with chemical peels for lichen amyloidosis: A case series

Cutaneous amyloidosis is a chronic dermatologic problem that can be extremely frustrating to patients and for which there are limited therapeutic options, often of inadequate efficacy. Patient quality of life is affected by the severe pruritus and cosmetic disfigurement of their lesions. First-line therapy for this condition is potent topical corticosteroids, but therapeutic efficacy is often limited by ineffective drug delivery to the target site. Intralesional kenalog can be a useful alternative for those with small, localized areas of disease involvement.

The thousand faces of the Sweet syndrome

Introduction: Sweet syndrome is an acute febrile neutrophilic dermatosis described in 1964 by Robert Douglas Sweet, that primarily affects individuals in their fifth to seventh decades. It can be classified into classic or idiopathic, parainflammatory, paraneoplastic, and pregnancy associated. Etiology is unknown, but many authors proposes an unusual hypersensitivity that may be mediated by cytokines, such as interleukin-1, followed by infiltration of neutrophils. Clinically, it is characterized by the abrupt onset of multiple tender, erythematous plaques or nodules.

Age-related changes affecting the cricoarytenoid joint seen on computed tomography

Georges Ziade, MD; Sahar Semaan, MD; Sarah Assaad, MPH; Abdul Latif Hamdan, MD, EMBA, MPH

Abstract

We conducted a retrospective chart review to compare four characteristics-cricoarytenoid joint ankylosis, narrowing, erosion, and density increases-in patients younger and older than 65 years. Our study population was made up of 100 patients, who were divided into two groups on the basis of age. The younger group (<65 yr) comprised 49 patients (27 men and 22 women), and the older group (≥65 yr) was made up of 51 patients (25 men and 26 women). Findings on computed tomography (CT) of the neck were used to determine whether each of the four characteristics was present or absent. Overall, we found only one statistically significant difference between the two groups: ankylosis was significantly more common in the older group (p = 0.036). When we looked further at the side of these anatomic changes, we found that the older group had significantly more right-sided and left-sided ankylosis than did the younger group (p = 0.026 for both), as well as significantly more left-sided narrowing (p = 0.028) (some patients had bilateral involvement). When we analyzed age as a continuous variable, older age was again associated with significantly more ankylosis (p = 0.047) and narrowing (p = 0.011). We conclude that CT can be useful for assessing radiologic changes in the cricoarytenoid joint in elderly patients during the workup of dysphonia and abnormal movement of the vocal folds.

Hepatozelluläres Karzinom

https://ift.tt/2o25VqN

Psychisches Wohlbefinden bei Patienten mit Leberzellkarzinom

Zusammenfassung

Hintergrund

Krebserkrankungen sowie die daraus resultierenden Folgen und Behandlungen stellen für Betroffene meist eine starke Belastung dar. Bei einem hepatozellulären Karzinom (HCC) handelt es sich um eine Krebserkrankung mit sehr schlechter Prognose. Mögliche Risikofaktoren, ein HCC zu entwickeln, nehmen in der Bevölkerung seit Jahren zu. Dennoch ist nur wenig über die psychische Belastung der Betroffenen bekannt.

Ziel der Arbeit

Ziel dieser Untersuchung war es, die psychische Belastung und Unterstützungswünsche von HCC-Patienten darzustellen.

Patienten und Methoden

In einer prospektiven Studie wurden Leberzellkarzinompatienten untersucht. Sie wurden zu Beginn und während eines Krankenhausaufenthalts, kurz vor der Entlassung aus demselben sowie 1/2 und 1 Jahr später befragt. Die psychische Belastung wurde mittels „hospital anxiety and depression scale" (HADS) erhoben. Zusätzlich wurden die Patienten gefragt, durch wen sie sich zusätzliche Betreuung wünschen. Bei der Auswertung wurde Häufigkeitsvergleiche mittels χ²-Test und Korrelationen mittels Pearson-Korrelationskoeffizient berechnet.

Ergebnisse

Insgesamt nahmen 97 Patienten an der Studie teil. Bei mehr als der Hälfte (56 %) lag der HADS-Gesamtwert zu Beginn der stationären Aufnahmen über 13, was einer überdurchschnittlichen psychischen Belastung entspricht. Über 90 % der befragten Patienten wünschten sich zu diesem Zeitpunkt psychosoziale Betreuung, zumeist durch Ärzte, Pflegekräfte und/oder Psychologen. Vor der Entlassung erhofften sich alle befragten Personen Unterstützung von Ärzten sowie Pflegekräften. Nach 1/2 Jahr wünschten sich die Betroffenen v. a. Unterstützung von Ärzten und Selbsthilfegruppen.

Diskussion

HCC-Patienten sind psychisch erheblich belastet, mit erhöhtem Betreuungsbedarf.

Schlafendoskopie und komplett konzentrischer Weichgaumenkollaps bei CPAP-Nutzungsproblemen

Zusammenfassung

Hintergrund

Mittel der ersten Wahl bei obstruktiver Schlafapnoe (OSA) ist die Überdrucktherapie (CPAP). Allerdings kann sie von vielen Patienten nicht ausreichend genutzt werden. Mit einer medikamenteninduzierten Schlafendoskopie (DISE) lässt sich das Kollapsmuster im oberen Atemweg gut beurteilen. Ziel der Arbeit war es, ein Patientenkollektiv mit CPAP-Nutzungsproblemen mittels DISE hinsichtlich von Nutzungsproblemen und Therapieempfehlungen auszuwerten.

Methode

Über einen Zeitraum von 5 Jahren wurden alle Patienten mit einem Apnoe-Hypopnoe-Index (AHI) ≥15/h mittels DISE retrospektiv ausgewertet und die empfohlenen Therapieoptionen erfasst.

Ergebnisse

Die Datenanalyse von 210 Patienten ergab, dass etwa zwei Drittel Maskenprobleme als ursächlich für die CPAP-Ablehnung angaben. Bei 75 % konnte ein komplett konzentrischer Kollaps (CCC) ausgeschlossen werden, diese Patienten wiesen niedrigere AHI-Werte auf und hatten häufiger eine Tonsillektomie (TE) als Patienten mit CCC. Patienten mit einem Body-Mass-Index (BMI) > 35 kg/m² hatten doppelt so oft einen CCC wie die mit einem BMI < 35 kg/m². Bei fast gleichem BMI und AHI war bei Patienten ohne vorangegangene TE knapp doppelt so oft ein CCC zu erkennen wie mit TE.

Schlussfolgerung

Die Reihung der Therapieempfehlungen verändert sich häufig bei der Berücksichtigung von CCC, BMI > 35 kg/m² und vorheriger TE.

Evolving Nomenclature of Thyroid Cancer

"Cancer is a word, not a sentence," acknowledged John Diamond as he embarked on an ultimately losing fight with oral carcinoma. It reflects the fear that the word cancer has instilled in the public for millennia. To many, a cancer diagnosis was, and remains, akin to a death sentence or, at the very least, a jarring call to battle. This connotation is rooted in the long-established theory of linguistic relativism, which stipulates that thought and action are determined a priori by language itself. Even today, our nuanced understanding of cancer biology and the inherent diversity of malignant processes has not erased the stigma and terror that the word evokes in our patients.

Medical Practice Entrepreneurship—Reply

In Reply We appreciate the comments made by Dr Meyers regarding the integration of business education into residency program curricula. As we all know, rising health care costs, decreasing reimbursement rates, and changes in American health care reform are forcing physicians to become more business-minded. However, a significant percentage of physicians indicate that their training did a fair or poor job of preparing them to manage the business aspects of medicine, which suggests that it would be useful for educators to reexamine residency training education to ensure that physicians are prepared for the practice environment.

Physical exercise contributes to cisplatin-induced nephrotoxicity protection with decreased CD4+ T cells activation

Publication date: September 2018

Source: Molecular Immunology, Volume 101

Author(s): Mariana Yasue Saito Miyagi, Marcela Teatin Latancia, Leonardo Abreu Testagrossa, Vinicius de Andrade-Oliveira, Welbert Oliveira Pereira, Meire Ioshie Hiyane, Lucas Maceratesi Enjiu, Marcus Pisciottano, Marilia Cerqueira Leite Seelaender, Niels Olsen Saraiva Camara, Mariane Tami Amano

Abstract

Cisplatin is a chemotherapy used to treat different types of cancer, such as testicular, bladder and head and neck. Physical exercise has been shown to improve cancer therapy and recently, it was demonstrated to be able to diminish side effects such as acute kidney injury (AKI), a common side effect in cisplatin treatment. In both cases, the modulation of inflammatory cytokines seems to be one of the mechanisms, but little is known about the immune cells in this process. Here, we investigated the role of CD4 + T cells in the AKI protection by physical exercise. We subjected C57Bl6 mice to long-term physical exercise (EX) before cisplatin treatment. Sedentary groups were used as control (CT). We confirmed that physical exercise decreased AKI by evaluating creatinine and Kim-1 levels, in the serum and kidney respectively. Analyzing the organs weight, we noticed a decrease in sedentary (CIS) and exercised (CIS-EX) cisplatin treated groups. Epididymal and brown adipose tissue weight were decreased in cisplatin treated subjects in comparison to untreated groups, as well as liver and spleen. We then investigated the profile of CD4 + T cells in the spleen and we observed increased levels of Tregs and CD4+CD25+ cells in CIS group, while CIS-EX presented similar amounts as control groups. Analyzing the kidney lymph nodes, we noticed a decrease of CD4+ cells in both CIS and CIS-EX group. However, a more activated phenotype (CD69+ and CD25+) was observed in CIS groups in comparison to CIS-EX group, as well as the presence of Tregs. We then investigated the production of cytokines by these cells and no difference among the groups was observed in cytokines production in splenic CD4 + T cells. However, a clear increase in TNF and IL-10 production was observed in CD4 + T cells from lymph nodes, while CIS-EX group presented similar levels as the control groups. We confirmed that physical exercise was able to diminish cisplatin-induced AKI with concomitant decrease in CD4 + T cell activation.

Generation of novel Id2 and E2-2, E2A and HEB antibodies reveals novel Id2 binding partners and species-specific expression of E-proteins in NK cells

Publication date: Available online 23 August 2018

Source: Molecular Immunology

Author(s): Jai Rautela, Laura F. Dagley, Tobias Kratina, Angaleena Anthony, Wilford Goh, Elliot Surgenor, Rebecca B. Delconte, Andrew I. Webb, Ngaire Elwood, Joanna R. Groom, Fernando Souza-Fonseca-Guimaraes, Lynn Corcoran, Nicholas D. Huntington

Abstract

NK cells are cytotoxic lymphocytes with a key role in limiting tumour metastases. In mice, the NK cell lineage continually expresses high levels of the Inhibitor of DNA-binding 2 (Id2) protein and loss of Id2 is incongruous with their survival due to aberrant E-protein target gene activity. Using novel Id2 and E-protein antibodies that detect both mouse and human proteins, we have extensively characterised Id2 and E-protein expression in murine and human NK cells. We detected clear expression of E2 A and HEB, and to a lesser extent E2-2 in murine NK cells. In contrast HEB appears to be the major E-protein expressed in human NK cells, with minor E2-2 expression and surprisingly, no E2 A detected in primary NK cells nor human NK cell lines. These novel antibodies are also functional in immunofluorescence and immunoprecipitation. Mass spectrometry analysis of Id2 immuno-precipitated from murine NK cells revealed a number of novel associated proteins including several members of the SWI/SNF-related matrix-associated actin-dependent regulator chromatin (SMARC) and Mediator complex (MED) families. Taken together, these data highlight the utility of novel Id2 and E-protein antibodies and caution against mouse models for understanding Id2/E-protein biology in NK cells given their clearly disparate expression patternbetween species.

Ancillary medications and outcomes in post-tonsillectomy patients

Ashley P. O'Connell Ferster, MD; Eric Schaefer, MS; Jane R. Schubart, MBA, PhD; Michele M. Carr, DDS, MD, PhD

Abstract

To investigate the impact of medications on outcomes after tonsillectomy, a retrospective review using the MarketScan database was performed. A total of 306,536 privately insured children and adolescents (1 to 17 years old) who underwent tonsillectomy/adenoidectomy were identified from 2008 to 2012. Pharmaceutical claims identified patients who received outpatient prescriptions for ibuprofen, steroids, or topical anesthetics until discharge and for medications for the treatment of attention deficit hyperactivity disorder (ADHD) or montelukast up to 14 days postoperatively. Logistic regression compared prescription claims to outcomes, including postoperative bleeding, dehydration, emergency department visits, and readmissions. Ibuprofen was the only medication associated with increased odds of postoperative bleeding (odds ratio [OR]: 1.45, 95% confidence interval [CI]: 1.07 to 1.95). Patients receiving steroids had lower odds of dehydration (OR: 0.74, 95% CI: 0.65 to 0.84) and emergency department visits (OR: 0.82, 95% CI: 0.76 to 0.88). Odds of dehydration were highest in patients taking ADHD medications (OR: 1.38, 95% CI: 1.15 to 1.66) and topical anesthetics (OR: 1.32, 95% CI: 1.10 to 1.59). Although causality cannot be assumed in observational studies, steroids and ibuprofen should be used judiciously.

Treatment outcomes in HPV-negative oropharyngeal cancer: Surgery plus radiotherapy vs. definitive chemoradiotherapy

Dominique Rash, MD; Megan E. Daly, MD; Blythe Durbin-Johnson, PhD; Andrew T. Vaughan, PhD; Allen M. Chen, MD

Abstract

We performed a retrospective study to compare clinical outcomes among 51 consecutively presenting patients-38 men and 13 women, aged 46 to 74 years (median: 57)-with locally advanced human papillomavirus (HPV)-negative oropharyngeal cancer who were treated with either primary surgery followed by postoperative radiotherapy (S/RT group; n = 22) or definitive chemoradiotherapy alone (CRT group; n = 29). Within the cohort, 45 patients reported a history of tobacco use, with a median intensity of 40 pack-years. In addition, 39 patients (76%) reported moderate to heavy alcohol use. At baseline, there were no statistically significant differences between the two cohorts in sex, median age, cancer stage, intensity of smoking history, and alcohol use (p > 0.05 for all). Radiation doses ranged from 40 to 70 Gy (median: 70). Follow-up ranged from 2 to 93 months (median: 29). After treatment, we found no difference between the S/RT group and the CRT group in the incidence of locoregional recurrence (36 vs. 24%; p = 0.43) or distant metastases (14 vs. 21%; p = 0.56). Likewise, the difference in 2-year estimates of progression-free survival in the two groups was not significant (66 vs. 62%; p = 0.64), nor was the difference in 2-year overall survival (75 vs. 76%; p = 0.83). We conclude that treatment with either (1) primary surgery followed by postoperative radiotherapy or (2) CRT for locally advanced HPV-negative oropharyngeal cancer results in similar outcomes. In view of the relatively poor prognosis for patients with HPV-negative disease compared with their HPV-positive counterparts, clinical trials to investigate intensifying treatment may be warranted.

A rare case of odontoameloblastoma in a geriatric patient

Pratyusha Yalamanchi, MD, MBA; Orly Coblens, MD; Meejin Ahn, DO; Steven B. Cannady, MD; Jason G. Newman, MD

Abstract

Odontoameloblastoma is an extremely rare tumor derived from odontogenic epithelium and mesenchyme. In the fewer than 20 reported cases, odontoameloblastoma is described as occurring in the maxilla or mandible of young men with a history of unerupted teeth. Here we report a case of a 73-year-old woman who presented to the dentist for routine cleaning and x-rays, which displayed a mandibular lesion. After referral to multiple providers, a biopsy of two involved teeth was obtained and computed tomography of the neck was performed, revealing a large, destructive lesion of the mandible. Histology was consistent with odontoameloblastoma. The patient underwent wide segmental mandibular resection and scapula tip free flap reconstruction. She recovered uneventfully and continues to have close follow-up, given the risk of recurrence. To the best of our knowledge, this is the first reported case of odontoameloblastoma in a patient over age 50. The goal of the authors is to raise awareness of this rare pathology and its diagnostic and management modalities.

Dacryocystorhinostomy with a thulium:YAG laser-a case series

Christopher Tang, MD; Scott Rickert, MD; Niv Mor, MD; Andrew Blitzer, MD, DDS; Martin Leib, MD

Abstract

We conducted a retrospective chart review of 27 patients-7 men and 20 women, aged 47 to 94 years (mean: 71.3)-with symptomatic epiphora secondary to dacryostenosis who had undergone thulium: YAG (Tm:YAG) laser dacryocystorhinostomy (DCR). Among them, dacryostenosis had been documented in 35 eyes by dacryocystography. The Tm:YAG procedure involved the administration of local anesthesia, after which a 600-μm laser fiber was inserted into the lacrimal canaliculi and then into the nasolacrimal duct. Under endoscopic visualization, the DCR was performed anterior and inferior to the middle turbinate, which created an opening. Silicone stents were then inserted and tied intranasally. In the immediate postoperative period, all 27 patients noted initial improvement. During a follow-up of 22 days to 25 months (mean: 11.3 mo), 24 of the 27 patients (89%) remained symptom-free, while the remaining 3 patients (11%) experienced a treatment failure and required revision surgery. To the best of our knowledge, only two articles on thulium laser therapy for DCR have been previously published, both approximately 25 years ago; both involved the use of a thulium along with holmium and chromium in cadavers. As far as we know, our case series is the largest in the English-language literature that has documented the use of the thulium in laser therapy for DCR, and it is the only in vivo study. We found that DCR with the Tm:YAG laser was an effective and affordable option for patients with symptomatic epiphora secondary to lacrimal obstruction.

Inflammatory myofibroblastic tumor of the epiglottis excised with a carbon dioxide laser: Case report and literature review

Blake Raggio, MD; Neil Chheda, MD

Abstract

Inflammatory myofibroblastic tumor (IMT) is a benign neoplasm of intermediate biologic potential. It rarely occurs in the larynx, and it has not been previously reported in the epiglottis. We treated a 66-year-old woman who presented with progressive dysphonia and a mass on her suprahyoid epiglottis. The tumor was completely excised with a CO2 laser; no adjuvant therapy was administered. Histopathology revealed that the mass was an IMT. No evidence of recurrence was noted after 6 months of follow-up. We present what we believe is the first case of an epiglottic IMT to be reported in the literature, and we propose CO2 laser excision without adjuvant therapy as an acceptable treatment.

Applicability of the real ear measurement for audiological intervention of tinnitus

Publication date: Available online 23 August 2018

Source: Brazilian Journal of Otorhinolaryngology

Author(s): Andressa Vital Rocha, Maria Fernanda Capoani Garcia Mondelli

Abstract

Introduction

Tinnitus is present in a large part of chronic health complaints, and it is considered a public health problem injurious to the individual's quality of life. Considering the increase of the world population associated with an increase of life expectancy, tinnitus remains a cause for medical concern, since during aging the occurrence of auditory impairments due to the deterioration of the peripheral auditory structures and central impairs the quality of life.

Objective

The aim of the present study was to analyze the applicability of real ear measurements for audiological intervention of tinnitus through specific evaluation, selection, verification and validation of the hearing aids combined with the sound generator.

Methods

Forty individuals of both genders with hearing loss and tinnitus complaints were deemed eligible to compose the sample. They were enrolled according to clinical symptoms and submitted to the following procedures: anamnesis and previous complaint history, high frequency audiometry, immittanciometry and acuphenometry with the research of psychoacoustic thresholds of pitch, loudness and minimum masking threshold, sound generator, in addition to the application of the Tinnitus Handicap Inventory and Visual Analog Scale tools. The entire sample was adapted with Siemens hearing aids and a sound generator, participated in a counseling session with support of digital material and evaluated in two situations: Initial Assessment (before the hearing aids and sound generator adaptation) and Final Assessment (6 months, after adaptation). The statistical analyzes were descriptive and inferential, adopted a significance level of 5% and the T-Paired Test and the Spearman Correlation test were performed.

Results

The results showed that there was a benefit with the use of hearing aids combined with a sound generator from the statistically significant values and strong correlations between the sound generator verification data regarding acuphenometry and the nuisance/severity questionnaires. Regarding the verification of the sound generator, it is important to highlight that the entire sample selected the effective acoustic stimulation based on the comfort levels, which was proved in the present study to be a sufficient intensity for positive prognosis, whereas the users' noises were found below the psychoacoustic thresholds of acuphenometry.

Conclusion

The present study concluded that the audiological intervention with any level of sound stimulus is enough to obtain a positive prognosis in the medium term. Data that specifies that the verification of sound generator was effective at the real ear measurements are important in the evaluation and intervention of the complaint. In addition, it points out that the greater the tinnitus perception, the greater its severity, and the greater the nuisance, the higher the psychoacoustics thresholds of frequency and the minimum threshold of masking.

Resumo

Introdução

O zumbido está presente em grande parte das queixas crônicas de saúde, sendo considerado um problema de saúde pública, prejudicial à qualidade de vida do indivíduo. Considerando o aumento da população mundial associado ao aumento da expectativa de vida, a tendência é que o zumbido permaneça como um motivo de preocupação, uma vez que com a idade a ocorrência de prejuízos auditivos decorrentes da deterioração das estruturas auditivas periféricas e centrais, ocasionam grande impacto negativo na qualidade de vida.

Objetivo

O objetivo do presente estudo foi analisar a aplicabilidade das medidas da orelha real para a intervenção audiológica do zumbido através de avaliação específica, seleção, verificação e validação do aparelho de amplificação sonora individual combinado ao gerador de som.

Método

Quarenta indivíduos de ambos os sexos com perda auditiva e queixa de zumbido foram considerados elegíveis para compor a amostra. Eles foram atendidos conforme a demanda clínica e submetidos aos seguintes procedimentos: anamnese e histórico prévio de queixa, audiometria de alta frequência, imitanciometria e acufenometria com pesquisa dos limiares psicoacústicos de pitch, loudness e limiar mínimo de mascaramento, gerador de som, além da aplicação das ferramentas tinnitus handicap inventory e escala visual analógica. Toda a amostra recebeu aparelho de amplificação sonora individual e gerador de som, ambos da marca Siemens, participaram de uma sessão de aconselhamento com apoio de material digital e foram avaliados em duas situações: Avaliação inicial (antes da adaptação dos aparelhos de amplificação sonora individual e gerador de som) e Avaliação final (6 meses após a adaptação). As análises estatísticas foram descritivas e inferenciais, adotando um nível de significância de 5% com a realização do teste t-pareado e o teste de correlação de Spearman.

Resultados

Os resultados mostraram que houve benefício com o uso de aparelho de amplificação sonora individual combinado ao gerador de som com base nos valores estatisticamente significantes e fortes correlações entre os dados da verificação do gerador de som em relação à acufenometria e os questionários de incômodo/gravidade. Em relação à verificação do gerador de sons, é importante destacar que toda a amostra selecionou a estimulação acústica efetiva baseada nos níveis de conforto, e no presente estudo demonstraram ser de intensidade suficiente para o prognóstico positivo, enquanto que os ruídos dos usuários estavam abaixo dos limiares psicoacústicos da acufenometria.

Conclusão

O presente estudo concluiu que a intervenção audiológica com qualquer nível de estímulo sonoro é suficiente para obter um prognóstico positivo em médio prazo. Os dados que demonstram que a verificação do gerador de som foi efetiva nas medidas da orelha real são importantes na avaliação e intervenção da queixa. Além disso, mostram que quanto maior a percepção do zumbido, maior a sua gravidade; e quanto maior o incômodo, maiores os limiares de frequência psicoacústica e o limiar mínimo de mascaramento.

Two cases of laryngeal fractures treated with titanium mesh fixation

Publication date: Available online 23 August 2018

Source: Auris Nasus Larynx

Author(s): Taku Sato, Takaharu Nito, Rumi Ueha, Takao Goto, Tatsuya Yamasoba

Abstract

The larynx plays a vital role in respiration, swallowing, and vocal function. Thus, laryngeal fractures that are not appropriately managed may lead to permanent dyspnea, dysphagia, and voice disorders. In cases of laryngeal fractures, surgical repair by internal fixation has been performed with materials such as thread, steel wire, and titanium miniplates. However, thyroid and cricoid cartilage have a complicated morphology, and ossification at each site in the cartilage is not uniform; thus, in some cases it is difficult to perform internal fixation with conventional methods. In this case report, we describe two patients who underwent successful fixation of fractures in their laryngeal cartilage after trauma by using titanium mesh with thread and screws. Since optimal reduction and fixation of fractured laryngeal cartilage cannot be performed with conventional methods in patients with unossified cartilage, titanium mesh may be considered a safe and reliable alternative.

Global Professional Behaviours and Networking Preferences of Young Otolaryngologists – An International Survey

Publication date: Available online 22 August 2018

Source: European Annals of Otorhinolaryngology, Head and Neck Diseases

Author(s): K.A. Stephenson, D. Ramdhani, I. Fournier, T. Ayad

Abstract

Aims

An international survey was conducted to explore the professional and regional spread of "young" otolaryngologists, their society membership and networking preferences, with relevance to global health and future initiatives.

Material and methods

Otolaryngologists under the age of 45 years who had attended the 2017 International Federation of Otorhinolaryngological Societies (IFOS) meeting were invited by e-mail to participate in an online survey. Basic demographic data and information regarding career geography and networking preferences was requested.

Results

A total of 928 responses (including 635 certified otolaryngologists and 268 trainees) were received from 2787 individuals invited to complete the survey. The overall response rate was 33.3%. Most otolaryngologists were based in an academic hospital. The spread of respondents likely reflects the European location of the meeting from which participants were identified; 61.2% of all respondents were based in Europe. International movement between career stages was evident. The principal preferred networking methods involved face-to-face contact whilst social media use was the method of choice for 13%.

Conclusion

This survey offers a present-day snapshot and is hoped to serve as a platform for further work. Little is known on a global scale regarding the professional behaviours and networking preferences of otolaryngologists. A greater understanding will facilitate not only education and research but also enable networking and global health work.

What is the availability of services for paediatric ENT surgery and paediatric surgery in Africa?

Publication date: Available online 22 August 2018

Source: European Annals of Otorhinolaryngology, Head and Neck Diseases

Author(s): S. Peer, I. Vial, A. Numanoglu, J.J. Fagan

Abstract

Background

Children constitute 50% of Africa's population. Sub-Saharan Africa has the highest under-five mortality rates in the world. This study is the first to document the availability of paediatric ENT and paediatric surgery services in Africa.

Objective

To determine the availability of paediatric ENT services in Africa, as well as that of paediatric surgery that would complement paediatric ENT.

Method

A descriptive observational study in the form of an online questionnaire was distributed by email to known ENT and paediatric surgeons based in Africa.

Results

Surgeons from twelve of 23 African countries responded to the survey. Seven countries had both ENT and paediatric surgery responses. In 8 of the 11 countries, the number of ENT surgeons per country was < 6% of that of the UK, with 1 ENT surgeon per 414,000 people and 1 paediatric surgeon per 1,181,151 people. Ten of 11 countries reported hearing assessments in schools were poor/unavailable. Seventy-three percent responded positively for access to rigid laryngoscopes, bronchoscopes, cameras and fibre optic cables, tracheostomy, anaesthesia and nurse practitioners. Access was reported as poor/unavailable for balloon dilators 73% (8/11 countries); CPAP machines 73% (8/11) and sleep studies 82% (9/11 countries). Flexible endoscopes were available in 50% (4/8 countries), 75% (6/8 countries) had access to a camera, monitor and stack. Thirty-eight percent (3/9 countries) reported no ENT specialists with paediatric training.

Conclusions

There is a great shortage of paediatric ENT and paediatric surgery services in Africa. More regional training opportunities and health infrastructure for these surgical specialties are needed. Collaborative development of paediatric ENT, surgery and anaesthesia should be considered to improve ENT-related child health in Africa.

Barriers to research among residents in Otolaryngology - Head & Neck Surgery around the world

Publication date: Available online 22 August 2018

Source: European Annals of Otorhinolaryngology, Head and Neck Diseases

Author(s): I. Fournier, K. Stephenson, N. Fakhry, H. Jia, R. Sampathkumar, J.R. Lechien, A.E. Melkane, A.Y. Bahgat, K. De Carvalho Lopes, T. Kennel, N. Teissier, T. Ayad

Abstract

Objectives

To document the challenges faced by residents in Otolaryngology - Head & Neck Surgery (OTL-HNS) around the world to successfully complete research projects. The second objective is to assess if the challenges are uniform worldwide.

Methods

A survey was sent to all OTL-HNS under 45 years old from the 2017 IFOS meeting. This survey was conducted by the YO-IFOS group (Young Otolaryngologists of the International Federation of Otolaryngological Societies). Data was collected for a period of 1 month. Demographic characteristics, information regarding research projects conducted and data concerning perceived barriers to completion of research projects were collected.

Results

Among the 2787 attendees, 928 responded to the survey (response rate = 33.3%). Of these 928 answers, 267 responses were from residents/interns in OTL-HNS, while 635 responses were from certified otolaryngologists. The three most frequent obstacles to conducting research projects for trainees were limited dedicated time (64%), insufficient financial resources (55%) and lack of education in research (45%). There was no statistical difference in these barriers among the different countries (P > 0.05).

Conclusion

This is the first international study that provides insight on trainee's challenges to conduct research projects during residency. Despite the notion that research is essential for generating new knowledge to guide patient care, many residents fail to successfully incorporate research in their surgical curriculum. These obstacles must be addressed by Otolaryngology - Head & Neck Surgery programs in order to facilitate and support resident's research.

Sleep Disorders and Atopic Dermatitis : a Two-Way Street?

Publication date: Available online 23 August 2018

Source: Journal of Allergy and Clinical Immunology

Author(s): Yung-Sen Chang, Bor-Luen Chiang

Abstract

Sleep disturbance is very common in patients with atopic dermatitis (AD), and is a major factor leading to impaired quality of life. Sleep disturbance is often viewed as one of the symptoms of AD and one of the measures of disease severity. In this review, we describe a variety of sleep disorders associated with AD and a wide range of impact that sleep disorders have on patients with AD. We also discuss our current understanding of the mechanism of sleep disturbance in AD. The relationship between sleep disorders and AD might be bi-directional and could form a vicious cycle. Therefore, we suggest viewing sleep disorders as a comorbidity of AD for which regular screening and bidirectional management strategies are indicated, with equal focus on maintaining disease control and implementing specific strategies to improve sleep.

Abstract

Purpose

To examine single stage laryngotracheal reconstruction (SSLTR) care to reduce complication and failure rate.

Methods

Forty-five patients that underwent primary SSLTR were examined retrospectively. All had pre-operative direct laryngoscopy and bronchoscopy, esophagoscopy with biopsy and MRSA screening. Pre-operative subglottic stenosis (SGS) grade and associated comorbidities were recorded. Intraoperative graft location and type was documented. Hospital course and results were evaluated and compared to cited literature.

Results

The median age at reconstruction was 2 years (0-15 years). 42.2% were male. 66.7% had gastroesophageal disease and 24.4% a MRSA history. Grade 2 SGS was noted pre-operatively in 37.8% and grade 3 or 4 in 57.7% of patients. Post-surgical hospital course was examined. 77.8% of patients were extubated on planned date. 95.6% of patients had operation specific successful decannulation. Graft type and variations of graft placement as well as MRSA and GERD status didn't affect procedure success rate. Active GERD was related to failure of extubation on planned day (p=0.02). An abnormal pre-operative swallowing examination was associated with higher complication rates (p=0.03).

Conclusion

Utilizing a more structured approach to SSLTR work-up and addressing potential SSLTR pitfalls may result in higher operation specific decannulation rates. Pre-operative GERD and swallowing dysfunction were associated with higher rates of adverse events.

Abstract

Schwannomas arising from the vagus nerve are extremely rare in children, with only 15 cases reported in the world literature.

We describe a pediatric case of cervical vagal nerve schwannoma successfully treated with cranial nerve-sparing surgery. Our patient presented extensive mass in the right side of the neck with ipsilateral Horner's syndrome. Her first sign, anisocoria, was diagnosed at the age of 1.5 y, making her the youngest vagal schwannoma case ever reported. Using an ultrasonic surgical aspirator and nerve monitoring, a multidisciplinary team successfully removed the mass with no recurrence after 2 years of follow-up.

A review of adenotonsillar hypertrophy and adenotonsillectomy in children after solid organ transplantation

Publication date: Available online 23 August 2018

Source: International Journal of Pediatric Otorhinolaryngology

Author(s): Jessica Roberts, Jason Powel, Michael Mather, Steven Powell, Malcolm Brodlie

Abstract

Objective

Paediatric solid organ transplantation is an increasingly successful treatment. Improved survival is paralleled by increased secondary complications of immunosuppression, including post-transplant lymphoproliferative disease (PTLD). PTLD frequently presents in Waldeyer's lymphatic ring. Adenotonsillar hypertrophy (ATH) is common in children, however in children after transplant, ATH may indicate PTLD. We review the literature on ATH and the role of adenotonsillectomy in children after transplantation.

Methods

A comprehensive literature search was performed on 26 t h September 2017 of Ovid Medline (1996 – September 2017), Embase (1996 -2017) and EBM reviews (Cochrane database of systematic reviews 2005 – September 20 t h 2017). Results were limited to English language publications within the last 20 years. Abstracts were screened for relevance to PTLD and ATH in the paediatric solid organ transplantation population. Screening of the bibliographies identified further articles.

Results

85 unique articles were screened to yield 18 relevant articles. 10 were retrospective studies and 8 were prospective studies.

Conclusion

In children, we report a PTLD incidence of up to 15% with up to 63% of cases presenting in the head and neck. Histological examination of adenotonsillectomy specimens found PTLD in a mean 5.7% (range 0 – 39%). We found a lack of prospective studies into this topic and further high quality research is needed. Clinical assessment of ATH in children after transplantation and when to perform a diagnostic adenotonsillectomy remains challenging. Children with ATH warrant prompt further investigation and support from colleagues in transplantation and oncology is required.

Side-related differences in sudden sensorineural hearing loss in children

Publication date: Available online 22 August 2018

Source: International Journal of Pediatric Otorhinolaryngology

Author(s): Kaitian Chen, Hongyan Jiang, Ling Zong, Xuan Wu

Abstract

Objective

Most studies on sudden sensorineural hearing loss (SSNHL) do not differentiate the outcomes within varied affected ears in children. The present study was designed to determine the clinical differences between unilateral and bilateral SSNHL in children.

Methods

The clinical data, from a total of 101 pediatric patients with SSNHL, was retrospectively analyzed from January 2003 to December 2016. The main outcome measures included basic characteristics, etiology, clinical symptoms and treatment courses.

Results

When the bilateral group (n = 28) was compared to the unilateral group (n = 73), neither gender nor onset of SSNHL was significantly different (p > 0.05 each); However, bilateral SSNHL tended to occur in younger ages (8.1 ± 4.0 yrs), with higher percentages of suspected etiologies (50%) and proportion of profound deafness (55.4%, p < 0.05 each). The short-term recovery rate was superior in the unilateral cases over the bilateral cases (37.0% vs. 12.5%, p < 0.05). Milder initial hearing threshold, early onset of treatment (5.6 ± 4.8 days) with unilateral involvement and an older age (11.3 ± 3.0 yrs) in bilaterally affected cases were associated with a better prognosis in this cohort. In addition, the unilateral group showed comparable outcomes, when sub-analyzed by comparison to that in either left- (n = 42) or right-sided (n = 31) SSNHL.

Conclusion

Although bilateral and unilateral pediatric SSNHL could cause partial to complete cochlear lesion, they may be relevant to distinct backgrounds. Our data also provides valuable information about demographics and outcomes of SSNHL in children.

L1CAM expression in uterine carcinosarcoma is limited to the epithelial component and may be involved in epithelial–mesenchymal transition

Abstract

Uterine carcinosarcoma (UCS) has been proposed as a model for epithelial–mesenchymal transition (EMT), a process characterized by a functional change facilitating migration and metastasis in many types of cancer. L1CAM is an adhesion molecule that has been involved in EMT as a marker for mesenchymal phenotype. We examined expression of L1CAM in UCS in a cohort of 90 cases from four different centers. Slides were immunohistochemically stained for L1CAM and scored in four categories (0%, < 10%, 10–50%, and > 50%). A score of more than 10% was considered positive for L1CAM. The median age at presentation was 68.6 years, and half of the patients (53.3%) presented with FIGO stage 1 disease. Membranous L1CAM expression was positive in the epithelial component in 65.4% of cases. Remarkably, expression was negative in the mesenchymal component. In cases where both components were intermingled, expression limited to the epithelial component was confirmed by a double stain for L1CAM and keratin. Expression of L1CAM did not relate to overall or disease-free survival. Our findings suggest L1CAM is either not a marker for the mesenchymal phenotype in EMT, or UCS is not a good model for EMT.

A 27-Month-Old Boy with Polyuria and Polydipsia

Psychogenic polydipsia is a well-described phenomenon in those with a diagnosed psychiatric disorder such as schizophrenia and anxiety disorders. Primary polydipsia is differentiated from psychogenic polydipsia by the lack of a clear psychotic disturbance. We present a case of a 27-month-old boy who presented with polyuria and polydipsia. Laboratory studies, imaging, and an observed water deprivation test were consistent with primary polydipsia. Polydipsia resolved after family limited his fluid intake and began replacing water drinking with other transition objects and behaviors for self-soothing. This case highlights the importance of water deprivation testing to differentiate between causes of polyuria, thereby avoiding misdiagnosis and iatrogenic hyponatremia. Secondly, primary polydipsia can result during the normal stages of child development without overt psychiatric disturbances.

Immunohistochemical classification of gastric cancer based on new molecular biomarkers: a potential predictor of survival

Abstract

Several classification systems have been described for stratifying patients with gastric carcinoma (GC). However, their prognostic value is low, and there is an urgent need for identification of molecular markers and development of new classifications. Retrospective study of 206 cases of GC diagnosed and surgically resected in our hospital between 2000 and 2017. Clinicopathological features of all cases were assessed and tissue microarrays were constructed for immunohistochemical (IHC) study. Patients were stratified based on IHC results. Mean patient age was 71 years and most patients were male (54.6%). Most tumors were located in the gastric antrum and body, and they were mostly fungoid or ulcerative lesions. GC were mainly intestinal-type tumors and 60.3% were diagnosed at pT3. 56.2% of patients showed recurrences and 29.4% died due to GC. According to our IHC classification, 23.5% of tumors showed microsatellite instability, 6% were E-cadherin negative, 53.5% were stable-p53 not overexpressed, and 17% were stable with p53 overexpression. IHC classification was significantly correlated with patient gender, gross morphology, Laurén classification, tumor necrosis, perineural infiltration, type of leading edge, and patient outcome. Multivariate analysis showed that IHC subtype was significantly and independently associated with overall survival, together with clinical symptoms, signet cell phenotype, tumor grade and vessel invasion. The application of IHC classifications based on molecular biomarkers in clinical practice can aid in the stratification of GC patients. More studies are needed to evaluate the reproducibility and clinical significance of these classifications.

Case of acute paraspinal pyomyositis in an elderly diabetic secondary to spread from urinary tract infection

A 73-year-old woman with medical history of diabetes and hypertension presented with right-sided back pain and night sweats of 1 month duration. On physical examination, there was costovertebral angle tenderness and her urinalysis was indicative for urinary tract infection. She was admitted and managed with intravenous antibiotics. On initial imaging, there was a right-sided retroperitoneal mass adjacent to right kidney. This was investigated further with MRI, which showed diffuse inflammation of right paraspinal muscles with two loculated abscesses. The abscesses were aspirated and the culture sent grew Streptococcus agalactiae (Group B Streptococcus) and the patient was treated with 6-week course of intravenous antibiotics.

Scrotal oedema: a misadventure of direct vision internal urethrotomy

Description 

A 30-year-old man presented with voiding lower urinary tract symptoms for 2 years due to bulbar urethral stricture. He had a history of appendectomy two and a half years ago during which he was catheterised. His retrograde urethrogram was suggestive of a short (<1 cm) bulbar urethral stricture (figure 1). After proper counselling, he was posted for direct vision internal urethrotomy (DVIU) under spinal anaesthesia. Immediately following the procedure, he developed scrotal oedema (figure 2). Perineal compression was given along with scrotal support. The patient was observed for 2 days in the ward; there was no increase in the oedema. He was subsequently discharged with an advice to keep a scrotal support and called on the 10th postoperative day. His oedema had completely resolved and his catheter was removed. He voided with a good flow rate of 27 mL/s and had a normal bell-shaped curve on uroflow...

A deceptive presentation of Tuberculosis hip as Staphylococcal infection, its successful management and literature review

A 71-year-old man presented with septic arthritis of the hip with an initial culture growth of methicillin-sensitive Staphylococcus aureus (MSSA) masking the diagnosis of tuberculosis (TB). Based on joint aspirate culture and sensitivity results, the patient was first diagnosed with MSSA arthritis. He was started on intravenous antibiotics and underwent washout and debridement of hip. During the procedure, the surgeons observed characteristic tubercular changes and samples were sent for tubercular testing. The reports of cultures for acid-fast bacilli and synovial biopsies confirmed our intraoperative suspicion of TB. Antitubercular medication was started and it helped patient to improve quickly. He completed 9 months of tubercular treatment regimen and at completion total hip replacement was offered. At 8-year follow-up, the patient was doing fine with no recurrence of infection in his hip. High index of suspicion for skeletal TB was raised based on clinical and radiological signs especially if there was a delay or absence of response to appropriate therapy.

Port site hernias following robotic colorectal surgery in people with obesity

Port site hernias are a rare complication following robotic surgery that can result in disastrous outcomes. We describe incarcerated port site hernias in two patients with obesity. Both patients required laparoscopic reduction. Following laparoscopic reduction, one patient's postoperative course was complicated by pneumatosis intestinalis, requiring exploratory laparotomy and subsequent small bowel resection. It is standard practice to not close the fascia of port sites less than 12 mm in robotic surgery. However, this allows for the rare possibility of small bowel herniation through the port site. We suggest that our patients' history of obesity and metabolic dysfunction contributed to difficult port retention during the case, and longer operating times which caused an increased amount of torque at the port site. Additionally, compared with laparoscopic surgery, robotic surgery is associated with increased torque at port sites. The combination of these risk factors extended the fascial defect, ultimately leading to the incarceration of small bowel in the port site.

Blood culture-negative endocarditis presenting as altered mental status

Blood culture-negative endocarditis (BCNE) is difficult to diagnose because one of the major criteria to raise suspicion for endocarditis, a positive blood culture, is absent. BCNE accounts for 2.5% to 31% of all cases of endocarditis. Our report describes a 69-year-old woman with end-stage renal disease who presented with altered mental status. Physical examination and testing, including complete blood count, comprehensive metabolic panel, chest X-ray and head CT were otherwise unremarkable. Brain MRI revealed multiple areas of decreased diffusion concerning for cardioembolic stroke. A transthoracic echocardiogram demonstrated an abnormality on the mitral valve. Operative evaluation revealed a purulent mitral valve with vegetative clumps. Cultures of the vegetation and the blood grew no organisms. BCNE is a rare entity; neurological abnormalities may be the only presenting signs/symptoms. Endocarditis should be considered among the causes of altered mental status, even in the absence of positive blood cultures.

Use of optokinetic chart stimulation to restore mobility and reduce ataxia in a patient with pseudo-Cushing ataxia

A 61-year-old patient was admitted to hospital after a fall. She presented with bilateral muscle weakness and severe ataxia. She was unable to maintain sitting balance or place feet on the floor and was unable to tolerate hoist transfers due to the severity of her ataxia. Nursing and physiotherapy staff found it difficult to sit her out of bed. Her physiotherapy intervention changed to optokinetic chart stimulation (OKCS) and sensory interaction for balance. After treatment for 5 days, her intention tremor fully resolved. At discharge, she was mobile with a wheeled zimmer walking frame and supervision of one person. At follow-up after 8 months, she was independently mobile without any walking aid in and around her house. She was going out shopping with her son. For recovery from ataxia, it is recommended that further research on restorative intervention at the nervous system level be carried out.

Ictal cardiorespiratory depression: a real risk for sudden unexpected death in epilepsy (SUDEP)?

A 61-year-old woman affected by nocturnal hypermotor seizures since the age of 2 years complained of epigastric discomfort and chocking sensation before seizure onset for the last 25 years. Telemetry unit monitoring revealed several focal seizures with left frontotemporal onset complicated with ictal asystole and apnoea. After pacemaker (PM) implantation, video-EEG monitoring coupled with extensive respiratory montage confirmed the presence of ictal central apnoea. Despite this huge ictal autonomic imbalance which is claimed to be a risk factor for sudden unexpected death in epilepsy, the patient had a 25-year history of similar seizures, questioning the need to perform PM implantation and assisted ventilation.

Physiological pituitary hyperplasia misinterpreted and treated as lymphocytic hypophysitis

Description 

A 19-year-old nulliparous eumenorrhoeic woman diagnosed with bilateral serous retinal detachment was referred for incidentally detected enlarged pituitary gland, seen on MRI of orbit. A focused MRI documented diffuse, symmetric enlargement of the pituitary gland having a convex superior surface abutting the optic chiasm (11.4 mm in antero-posterior x 16.9 mm in transverse x 9.3 mm in height) with marked homogeneous gadolinium enhancement with a thickened, non-tapering stalk (3.5 mm at infundibulum) and a conspicuous eutopic posterior pituitary bright spot (figure 1). A comprehensive work-up remained unremarkable (table 1). In view of symmetric, enlarged pituitary demonstrating intense homogeneous contrast enhancement and a thickened (>2–3 mm thickness is considered pathological), non-tapering pituitary stalk in this non-pregnant individual, a diagnosis of lymphocytic hypophysitis (LH) was considered, after ruling out the other possible differential diagnosis. Pulse therapy with intravenous methylprednisolone was initiated followed by maintenance therapy with daily prednisolone gradually tapered over 12 weeks....

Feeding difficulty in an infant: an unusual cause

A 10-month-old girl, with spondyloepiphyseal dysplasia congenita and posterior cleft palate had presented at 23 days of life with history of feeding difficulties. A diagnosis of oropharyngeal dysphagia and gastro-oesophageal reflux disease was made, for which she was started on nasogastric tube feeding and oral ranitidine. However, she continued to have poor development of oropharyngeal skills, persistent reflux as well as poor growth and was planned for gastrostomy at 10 months of age. She underwent soluble upper gastrointestinal contrast study prior to gastrostomy placement to rule out anatomical causes of vomiting, which showed the greater curvature of the stomach to be lying above the lesser curvature, suggesting a diagnosis of gastric volvulus, likely chronic, given that she did not have a history of abdominal distension, irritability or recurrent vomiting. On diagnosis of gastric volvulus, our patient underwent laparoscopic gastrostomy creation and is doing well postoperatively.

Left shoulder pain in patients with old myocardial infarction could be a neuropathic pain from spinal epidural haematoma

Description 

A 66-year-old Japanese man with medical history of old myocardial infarction and on daily aspirin presented to the emergency department with sudden onset of severe left shoulder pain. He reported no prior trauma and denied cold sweat, vomiting, chest or back pains. At the time of initial evaluation, cardiac and neurological examinations were normal and there was no tenderness over the shoulder joints or the spine. A diagnosis of acute myocardial infraction or aorta dissection was first suspected. However, ECG, serum troponin T concentration and contrast-enhanced CT of the chest showed negative results.

The patient was admitted to the emergency department under the diagnosis of possible acute coronary syndrome. But, several hours later, he suddenly developed mild weakness of the left upper and lower extremities without facial muscle involvement. Urgent MRI revealed cervical spinal epidural haematoma (SEH) with spinal cord compression mainly to the left side (

Rapid hair depigmentation in patient treated with pazopanib

Pazopanib is multitargeted tyrosine kinase inhibitor used for the treatment of metastatic renal cell carcinoma. Hair colour change is a common side effect of pazopanib therapy which usually develops gradually during few months of therapy. We report a case of the patient who developed multiple pazopanib side effects followed by rapid overnight hair and eyebrow depigmentation after only few weeks of therapy. In our research, we found no literature data of rapid loss of hair pigment due to therapy with any of listed multitargeted tyrosine kinase inhibitors. To the best of our knowledge, this is the first such case being reported. We presume that summation of different mechanisms probably led to rapid hair depigmentation. Considering the fact that pazopanib treatment was very effective in our patient, this side effect could be a good predictor of therapy success, although it presents very stressful event for patient and his family.

Examen mycologique en dermatologie

Résumé

Les dermatomycoses sont des infections dermatologiques très fréquentes en pratique de ville puisqu'elles peuvent atteindre un tiers de la population. Cependant, leur symptomatologie est souvent commune avec d'autres affections ou infections cutanées, et peut être très atypique. Il n'est donc pas possible de poser un diagnostic de certitude par un simple examen clinique. C'est pourquoi le diagnostic mycologique est indispensable pour confirmer ou infirmer une dermatomycose, et ne se discute pas lorsqu'un antifongique systémique doit être proposé comme dans le traitement d'une teigne du cuir chevelu et de la barbe, ou d'une onychomycose. Il devient indispensable lorsqu'un traitement prescrit sur l'aspect clinique des lésions est en échec ou si les lésions cutanées récidivent. La confirmation d'une mycose permet de prescrire un traitement antifongique et la négativité de l'examen justifie d'envisager une autre cause aux lésions observées. Néanmoins, quelle que soit la technique du diagnostic mycologique, la qualité de sa réponse dépend avant tout de la qualité du prélèvement sur le site infecté, mais aussi de l'expertise du biologiste. L'examen mycologique classique demeure le plus informatif, le moins cher, et le seul examen capable d'isoler le champignon responsable quelle que soit la mycose : dermatophytose ; scytalidiose ; infection unguéale à moisissure ; candidose ; infections à Malassezia sp. C'est le seul examen capable d'identifier les variations épidémiologiques. Toutes les autres techniques récemment proposées reposent sur la simple mise en évidence d'éléments fongiques sans identification de l'espèce fongique ou sont dépendantes d'une banque de données de champignons généralement très incomplète.

Abstract

Dermatomycoses are dermatological infections very commonly encountered in private dermatological practice since they affect up to one third of the population. However, the symptoms are very often shared by other skin infections and disorders and may be highly atypical. It is thus impossible to make a diagnosis with any certainty on clinical grounds alone. For this reason, mycological diagnosis is essential to either confirm or rule out dermatomycosis, and is unavoidable when antifungal therapy is required for the treatment of ringworm of the scalp or beard, or for onychomycosis. It is also vital where therapy guided by the clinical appearance of lesions has failed or in the event of recurring skin lesions. Confirmation of mycosis enables antifungals to be initiated and a negative test warrants investigation for other underlying causes for the lesions seen. However, regardless of the mycological diagnostic technique employed, the quality of the results depends chiefly on the quality of sampling of the infected site, but also on the expertise of the microbiologist. Standard mycological testing remains the most informative, the least expensive and the sole examination capable of isolating the causative fungus irrespective of the type of mycosis, such as dermatophytosis, scytalidiosis, mould-induced ungual infection, candidiasis, or infections due to Malassezia sp. This is the only examination able to identify epidemiological variations. All other more recent techniques are either based upon simple demonstration of the fungal elements involved, without identification of the fungal species in question, or else they are reliant upon a fungal database that is generally highly incomplete.
