Priapism due to essential thrombocythaemia: a rare causation

Priapism is rarely caused by essential thrombocytosis, a disorder characterised by increased number of megakaryocytes. We report a case of a 21-year-old man who presented with priapism and on investigation was found to have essential thrombocytosis as the cause.

Renal cell carcinoma presenting as a cutaneous horn and nodules on the gingiva and scalp

A 63-year-old man presented with a pulsatile cutaneous horn on the nose and multiple angiomatous nodules on the gingiva and scalp, which appeared over 2 months. He had severe hypercalcaemia, lytic lesions in multiple bones and acute kidney injury. Excision biopsy from the gingival nodule showed a clear cell neoplasm. The bone marrow showed atypical cells with similar morphology. Imaging showed a 7 cmx7.5 cm mass at the upper pole of the left kidney with metastases to the bones, liver and lung. Immunohistochemistry was consistent with metastatic renal cell carcinoma. Renal cell carcinoma presenting as a cutaneous horn is extremely rare and to the best of our knowledge only one other case was found in the literature. There was visible regression in the size of the cutaneous horn and nodules following initiation of pazopanib therapy. However, he succumbed to his illness a month later.

Bilateral optic disc coloboma

Description

A 5-month-old male child was brought with the history of right-sided corneal opacity noticed for the past 2 months. The baby was immunised until now with an uneventful antenatal and peripartum history. Ocular examination showed normal sized cornea having a paracentral nebular opacity along the inferior and nasal aspect without any discharge or significant exposure keratopathy. The baby was able to fix at the light with each eye separately, the anterior chamber in both the eyes was of normal depth having a clear lens and retinal examination showed a well-defined posteriorly excavated area along the inferior portion of the optic disc in both the eyes. Sleeping intraocular pressures were 10 and 12 mm Hg in right eye and left eye, respectively. Posterior segment B-scan ultrasound showed a well-defined symmetric excavation along the inferior aspect of the optic disc in both the eyes with an axial length of 20 mm...

Idiopathic spontaneous lesser sac haematoma: a perplexing case of abdominal apoplexy

A 37-year-old woman presented with a 3-hour history of back pain, nausea and vomiting and an episode of syncope. A fluid collection in the lesser sac was detected on ultrasound and CT scan. Emergency laparoscopy and subsequent laparotomy were performed and a large blood clot was evacuated from the lesser sac. No identifiable source or predisposition to bleeding was found. She made a full recovery postoperatively. There are few reported cases of spontaneous intraperitoneal haemorrhage. In a third of cases, there is no identifiable source of bleeding. Unfortunately, patients present late with non-specific symptoms and a prompt diagnosis is difficult to make. The case reiterates the importance of awareness of lesser sac haematoma formation; an unusual clinical entity with a high morbidity and mortality rate. A high index of suspicion, radiological adjuncts and appropriate surgical intervention, especially in unstable patients, is essential for a good outcome.

Successful treatment of direct carotid-cavernous fistula in a patient with Ehlers-Danlos syndrome type IV without arterial puncture: the transvenous triple-overlay embolization (TAILOREd) technique

We report successful transvenous treatment of direct carotid–cavernous fistula in a patient with Ehlers–Danlos syndrome type IV using a novel triple-overlay embolization (TAILOREd) technique without the need for arterial puncture, which is known to be highly risky in this patient group. The TAILOREd technique allowed for successful treatment using preoperative MR angiography as a three-dimensional overlay roadmap combined with cone beam CT and live fluoroscopy, precluding the need for an arterial puncture.

Physiologic Considerations in Trauma Patients Undergoing Resuscitative Endovascular Balloon Occlusion of the Aorta

Resuscitative endovascular balloon occlusion of the aorta is a new procedure for adjunctive management of critically injured patients with noncompressible torso or pelvic hemorrhage who are in refractory hemorrhagic shock, ie, bleeding to death. The anesthesiologist plays a critical role in management of these patients, from initial evaluation in the trauma bay to definitive care in the operating room and the critical care unit. A comprehensive understanding of the effects of resuscitative endovascular balloon occlusion of the aorta is essential to making it an effective component of hemostatic resuscitation.

Resuscitative Endovascular Balloon Occlusion of the Aorta: Principles, Initial Clinical Experience, and Considerations for the Anesthesiologist

imageResuscitative endovascular balloon occlusion of the aorta (REBOA) is an endovascular technique that allows for temporary occlusion of the aorta in patients with severe, life-threatening, trauma-induced noncompressible hemorrhage arising below the diaphragm. REBOA utilizes a transfemoral balloon catheter inserted in a retrograde fashion into the aorta to provide inflow control and support blood pressure until definitive hemostasis can be achieved. Initial retrospective and registry clinical data in the trauma surgical literature demonstrate improvement in systolic blood pressure with balloon inflation and improved survival compared to open aortic cross-clamping via resuscitative thoracotomy. However, there are no significant reports of anesthetic implications and perioperative management in this challenging cohort. In this narrative, we review the principles, technique, and logistics of REBOA deployment, as well as initial clinical outcome data from our level-1 American College of Surgeons–verified trauma center. For anesthesiologists who may not yet be familiar with REBOA, we make several suggestions and recommendations for intraoperative management based on extrapolation from these initial surgical-based reports, opinions from a team with increasing experience, and translated experience from emergency aortic vascular surgical procedures. Further prospective data will be necessary to conclusively guide anesthetic management, especially as potential complications and implications for global organ function, including cerebral and renal, are recognized and described.

Esthetic dermatology and emotional well-being according to gender

Summary

Introduction

There has been an increase in the demand for esthetic dermatology treatments within the general population. The purpose of this study was to analyze, within the scope of general population, the relationship between people's perception of esthetic dermatology treatments and emotional well-being, as well as for differences in gender.

Methods

The Aesthetic Dermatology and Emotional Well-Being (DEBIE) Scale, [Journal of Cosmetic Dermatology vol. 13 (2014) 336-345] was applied to 770 Spanish people over 18 years old. The scale is structured according to six factors and classified into two dimensions: (1) Emotional Well-Being and (2) Perception of Aesthetic Dermatology. Cronbach alpha for the total scale was very high (0.90). Data analysis includes the following: (1) bivariate correlations with Pearson's coefficient; (2) gender differences through Student's t test, and (3) the effect size through R2 and Cohen's d.

Results

A statistically significant relationship which is directly proportional has been identified between the degree of emotional well-being of people (self-esteem and assertiveness, optimism, and motivation) and the knowledge and attitude toward Aesthetic Dermatology. There are statistically significant differences according to gender: Women have a lower level of emotional well-being than men, as well as greater knowledge and more positive attitude toward Aesthetic Dermatology.

Conclusions

People who are familiar with Aesthetic Dermatology and have a better attitude toward it, are also more self-confident, more optimistic and more motivated; with emotional strength. Regarding gender, it is expected that women may seek more consultation and esthetic dermatology treatments than men do.

Development of the gut microbiota in infancy and its impact on health in later life

Publication date: Available online 18 August 2017
Source:Allergology International
Author(s): Masaru Tanaka, Jiro Nakayama
Gut microbial ecology and function are dynamic in infancy, but are stabilized in childhood. The 'new friends' have a great impact on the development of the digestive tract and host immune system. In the first year of life, especially, the gut microbiota dramatically changes through interactions with the developing immune system in the gut. The process of establishing the gut microbiota is affected by various environmental factors, with the potential to be a main determinant of life-long health. In this review, we summarize recent findings regarding gut microbiota establishment, including the importance of various factors related to the development of the immune system and allergic diseases later in life.

Comparative analysis of the effects of CO 2 fractional laser and sonophoresis on human skin penetration with 5-aminolevulinic acid

Abstract

Successful delivery of a photosensitizer into the skin is an important factor for effective photodynamic therapy (PDT). The effective method to increase drug penetration within short incubation time overcoming skin barrier have been investigated. This study was performed to analyze and compare the effectiveness of ablative fractional laser (FXL) pretreatment and/or sonophoresis for enhancing the penetration of 5-aminolevulinic acid (ALA) into human skin in vivo. Twenty-four identical 1 × 1 cm2 treatment areas were mapped on the backs of ten healthy male subjects. Each area received FXL pretreatment and/or sonophoresis with different energy settings and ALA incubation times. After treatments, porphyrin fluorescence reflecting the ALA penetration were measured. Application of ablative CO2 FXL pretreatment resulted to higher fluorescence intensities than the non-treatment group. Incubation times were positively correlated with the increments of ALA penetration. However, increasing pulse energy or combining with sonophoresis did not show additional positive effects on ALA penetration. Ablative CO2 FXL pretreatment effectively facilitated ALA penetration in human skin in vivo. Ablative CO2 FXL alone without sonophoresis setting pulse energy of 10 and 20 mJ with more than 60 min of ALA incubation time could be an ideal setting for ALA penetration.

Condylar positions before and after bilateral mandibular distraction osteogenesis in children with Pierre Robin sequence

This study aimed to analyze the changes in mandibular morphology after bilateral mandibular distraction osteogenesis (BMDO) in children with Pierre Robin sequence. The positions of the condyles were analyzed in reconstructed three-dimensional craniomaxillofacial images obtained for 18 children before and 8–12 weeks after BMDO. Differences between pre- and postoperative parameters were assessed using paired t-tests. After surgery, a significant decrease in superior joint space was detected (P<0.05), but no change in anterior joint space or posterior joint space was observed.

The WFSA Global Anesthesia Workforce Survey

imageBACKGROUND: Safe anesthesia and surgical care are not available when needed for 5 billion of the world's 7 billion people. There are major deficiencies in the specialist surgical workforce in many parts of the world, and specific data on the anesthesia workforce are lacking. METHODS: The World Federation of Societies of Anaesthesiologists conducted a workforce survey during 2015 and 2016. The aim of the survey was to collect detailed information on physician anesthesia provider (PAP) and non-physician anesthesia provider (NPAP) numbers, distribution, and training. Data were categorized according to World Health Organization regional groups and World Bank income groups. RESULTS: We obtained information for 153 of 197 countries, representing 97.5% of the world's population. There were marked differences in the density of PAPs between World Health Organization regions and between World Bank income groups, ranging from 0 to over 20 PAP per 100,000 population. Seventy-seven countries reported a PAP density of

Lack of Association Between the Use of Nerve Blockade and the Risk of Persistent Opioid Use Among Patients Undergoing Shoulder Arthroplasty: Evidence From the Marketscan Database

imageBACKGROUND: Persistent opioid use following surgery has received increasing attention from policymakers, researchers, and clinicians. Perioperative nerve blockade has been hypothesized to decrease the risk of persistent opioid use. We examined whether nerve blockade was associated with a decreased risk of persistent opioid use among patients undergoing shoulder arthroplasty, a procedure with high rates of persistent postoperative pain. METHODS: Using health care claims data, we constructed a sample of 6695 patients undergoing shoulder arthroplasty between 2002 and 2012 and used billing data to identify the utilization of nerve blockade. We then used a multivariable logistic regression to estimate the association between nerve blockade and 2 measures of opioid use: having filled at least 1 prescription for an opioid between postoperative days (PODs) 0 and 90, and between POD 91 and 365. This regression adjusted for a variety of potential confounders, such as preoperative opioid use and medical history. RESULTS: There was no association between nerve blockade and our 2 measures of persistent opioid use: adjusted odds ratio, 1.12 (97.5% confidence interval, 0.939–1.34; P = .15) for opioid use between POD 0 and 90, and adjusted odds ratio, 0.997 (97.5% confidence interval, 0.875–1.14; P = .95) for opioid use between POD 91 and 365. CONCLUSIONS: Although the use of perioperative nerve blockade may offer short-term benefits, in this study, it was not associated with a reduction in the risk of persistent opioid use for patients undergoing shoulder arthroplasty.

Lack of Association Between the Use of Nerve Blockade and the Risk of Postoperative Chronic Opioid Use Among Patients Undergoing Total Knee Arthroplasty: Evidence From the Marketscan Database

imageBACKGROUND: Total knee arthroplasty (TKA) is associated with high rates of prolonged opioid use after surgery (10%–34%). By decreasing opioid use in the immediate postoperative period, perioperative nerve blockade has been hypothesized to decrease the risk of persistent opioid use. METHODS: Using health care utilization data, we constructed a sample of 120,080 patients undergoing TKA between 2002 and 2012 and used billing data to identify the utilization of peripheral or neuraxial blockade. We then used a multivariable logistic regression to estimate the association between nerve blockade and the risk of chronic opioid use, defined as having filled ≥10 prescriptions or ≥120 days' supply for an opioid in the first postsurgical year. Our analyses were adjusted for an extensive set of potential confounding variables, including medical comorbidities, previous opioid use, and previous use of other medications. RESULTS: We did not find an association between nerve blockade and the risk of postsurgical chronic opioid use across any of these 3 groups: adjusted relative risk (ARR) 0.984 for patients opioid-naïve in the year before surgery (98.3% confidence interval [CI], 0.870–1.12, P = .794), ARR 1.02 for intermittent opioid users (98.3% CI, 0.948–1.09, P = .617), and ARR 0.986 (98.3% CI, 0.963–1.01, P = .257) for chronic opioid users. Similar results held for alternative measures of postsurgical opioid use. CONCLUSIONS: Although the use of perioperative nerve blockade for TKA may improve short-term outcomes, the analyzed types of blocks do not appear to decrease the risk of persistent opioid use in the longer term.

3D-printed tracheoesophageal puncture and prosthesis placement simulator

A tracheoesophageal prosthesis (TEP) allows for speech after total laryngectomy. However, TEP placement is technically challenging, requiring a coordinated series of steps. Surgical simulators improve technical skills and reduce operative time. We hypothesize that a reusable 3-dimensional (3D)-printed TEP simulator will facilitate comprehension and rehearsal prior to actual procedures.

Reliability of Thyroid FNAC as a Single Diagnostic Modality: A Systematic Review

Abstract

To determine the reliability of thyroid FNAC as a single diagnostic modality in the case of nodular neoplastic lesions of the thyroid. Multiple databases were searched using the MESH terms thyroid*lesion*nodule*neoplasm*fine needle aspiration*histopathology*correlation. Meta analyses, RCTs, cohort or case control studies and case series were searched. 61 studies were examined to verify the search results after applying the inclusion and exclusion criteria. 422 studies were excluded after the first screening, leaving 61 full text articles. These were further analyzed for outcomes, and ultimately 9 studies were chosen for the final synthesis on the basis of clear recommendations given. FNAC as a single modality for the diagnosis of nodular neoplastic thyroid lesions is highly variable and therefore unreliable. The diagnostic yield may be improved if the Bethesda system of reporting is applied.

Publication date: Available online 18 August 2017
Source:European Annals of Otorhinolaryngology, Head and Neck Diseases
Author(s): M. Balaguer, J. Percodani, V. Woisard
IntroductionThe present prospective study sought to draw up and validate a self-assessment questionnaire for disability following head and neck cancer treatment.Material and methodThe Carcinologic Handicap Index (CHI) was designed empirically based on the Voice Handicap Index. It comprises 9 dimensions, self-assessed by the patient: pain, swallowing, feeding, respiration, phonation, hearing, vision, olfaction-gustation, and psychosocial. For each dimension, 4 items are scored in terms of frequency, providing dimension and global scores. The CHI was tested on 86 head and neck cancer patients (pathologic group: male predominance; mean age, 59 years) and 18 control subjects, for validation.Results and discussionGlobal internal coherence was 0.905 (Cronbach alpha); content validity (r, between questionnaire scores and corresponding visual analog scales) ranged between 0.6 and 0.8 except for the vision dimension and for total score compared to general health rating on VAS (r≤0.5: i.e., the pathology did not directly impair vision and was only one factor among others affecting general health status); temporal validity was satisfactory (r>0.7; P<0.0001) except on the respiration dimension (r=0.624, probably due to fluctuation in pulmonary congestion). Impact on swallowing, feeding and respiration varied with lesion site. There were no significant differences between patients and controls on the pain, hearing and vision dimensions.ConclusionThe CHI showed acceptable psychometric qualities and can be considered as an authentic clinical tool for health professionals, assessing the impact of ENT pathology on quality of life, mainly in the functional domains directly affected by the pathology or treatment.

Transoral bisected resection for T1-2 oral tongue squamous cell carcinoma to secure adequate deep margin

alertIcon.gif

Publication date: October 2017
Source:Oral Oncology, Volume 73
Author(s): Nayeon Choi, Jae-Keun Cho, Eun Kyu Lee, Sung Jun Won, Bo Young Kim, Chung-Hwan Baek
BackgroundTo investigate the clinical usefulness of transoral bisected resection (TBR) asa new method to secure adequate deep resection margin in T1-2 oral tongue squamous cell carcinomas (SCC).MethodsAmong 75 patients with cT1-2N0 oral tongue SCCs, 45 (60%) received transoral en-bloc resection (TER) while 30 (40%) received patients underwent TBR. Primary tumor resection was performed with 1.5-cm surgical resection margin for both groups. Mucosal and deep resection margins, adjuvant treatments including re-resection of the tongue and cheomoradiotherapy, local and regional recurrence free survival, and overall survival were compared between the two groups.ResultsMean deep resection margin in the TBR group was 9.9mm (95% CI: 8.4–11.4mm), which was significantly (P<0.001) wider than that of the TER group (mean: 5.4mm, 95% CI: 4.5–6.3mm). However, mucosal resection margins were not significantly (P=0.153) different between the two groups. Re-resection of tongue was performed for 6 (13.3%) of 17 (37.8%) patients with inadequate deep resection margin in the TER group and none (0%) in 4 (13.3%) patients with inadequate deep resection margin in the TBR group. Adjuvant radiation due to inadequate deep resection margin was performed for 6.7% of patients in both groups. The TBR group had better local recurrence free survival than the TER group. However, regional recurrence free survival and overall survival were not significantly different between the two groups.ConclusionTBR could provide adequate deep resection margin for early stage tongue cancers with better local tumor control than TER. It can decrease the necessity of adjuvant treatment for re-resection of the tongue.

Association between Periodontitis and Severe Asthma in Adults: A Case-Control Study

Abstract

Objective

To evaluate the association between periodontitis and severe asthma, with participants in treatment for severe asthma, controlled by therapy.

Methods

A case-control investigation was performed to compare 130 adults with severe asthma with 130 without asthma. Individuals with periodontitis were those with ≥ 4 teeth with ≥ 1 site with probing depth ≥ 4 mm, clinical attachment level ≥ 3 mm, and bleeding upon probing at the same site. Severe asthma diagnosis was based on Global Initiative for Asthma criteria.

Results

Association between exposure to periodontitis and severe asthma was found: ORcrude= 2.98 (95%CI: 1.74 to 5.11). When confounders were considered, the association between exposure to periodontitis and severe asthma was maintained: ORadjusted = 3.01 to 3.25. Individuals with periodontitis had about a three-fold increased risk of severe asthma than those without periodontitis. Frequency of periodontitis in participants with severe asthma was greater than that of those without asthma (46.6% vs 22.3%, p≤0.05).

Conclusions

Association between periodontitis and severe asthma was observed. Further investigation is required to determine the direction of this relationship. It may be causal, but it may also be a consequence of the immunopathological process that characterizes asthma, or else, consequence of the medication used for treatment.

Importance of bicarbonate transport in pH control during amelogenesis – need for functional studies

Abstract

Dental enamel, the hardest mammalian tissue, is produced by ameloblasts. Ameloblasts show many similarities to other transporting epithelia although their secretory product, the enamel matrix, is quite different. Ameloblasts direct the formation of hydroxyapatite crystals, which liberate large quantities of protons that then need to be buffered to allow mineralization to proceed. Buffering requires a tight pH regulation and secretion of bicarbonate by ameloblasts. Many investigations have used immunohistochemical and knock-out studies to determine the effects of these genes on enamel formation, but up till recently very little functional data was available for mineral ion transport. To address this, we developed a novel 2D in vitro model using HAT-7 ameloblast cells. HAT-7 cells can be polarized and develop functional tight junctions. Furthermore, they are able to accumulate bicarbonate ions from the basolateral to the apical fluid spaces. We propose that in the future the HAT-7 2D system along with similar cellular models will be useful to functionally model ion transport processes during amelogenesis. Additionally, we also suggest that similar approaches will allow a better understanding of the regulation of the cycling process in maturation-stage ameloblasts, and the pH sensory mechanisms, which are required to develop sound, healthy enamel.

Vibrant Soundbridge can improve the most comfortable listening level in sensorineural hearing loss: our experience of 61 patients

Abstract

In auditory rehabilitation, the most comfortable listening level (MCL) is important because the conversation partners of patients with hearing impairment are often individuals with normal hearing. Thus, normalizing MCL can help patients with hearing loss to reduce the communication handicap with individuals with normal hearing.

While active middle ear implants demonstrate comparable performance with conventional hearing aids (HA) with regard to functional hearing gain and speech intelligibility, little is known about the effect of middle ear implants on the MCL. Therefore, we evaluated the MCL of active middle-ear implants compared with that of conventional HA in patients with moderate and moderate-to-severe sensorineural hearing loss (SNHL).

We found that the Vibrant Soundbridge (VSB) active middle-ear implant had a pure-tone threshold similar to conventional HA. However, the MCL in VSB-aided conditions was significantly lower (by ~10 dB) than for HA-aided conditions. In addition, the significant improvement in MCL was attributable to robust amplifications at 1 kHz and 2 kHz compared with conventional HA.

VSB implantation nearly normalized MCL for patients with SNHL. In terms of normalizing MCL, VSB implantation is a good choice for hearing rehabilitation in patients with SNHL.

Otomycosis in immunocompetent patients: Clinical and mycological features. Our experience with 40 cases

Abstract

A male patient, in his third decade, with pruritus and hearing loss is the typical clinical presentation of otomycosis in immunocompetent cases.

Summer is the season most frequently involved in otomycosis patients, high temperature and humidity are common environmental factors.

Microscopic direct exam has a 60% sensitivity for detecting fungal disease.

Immunocompetent patients are infected in the majority of cases by Aspergillus, being Aspergillus niger the most frequent species.

Culture remains the gold standard in the diagnosis of this disease.

Potential savings in the diagnosis of vestibular schwannoma

Abstract

Magnetic resonance imaging (MRI) is used to screen patients at risk for vestibular schwannoma (VS). These MRIs are costly and have an extremely low yield; only 3% of patients in the screening population has an actual VS. It might be worthwhile to develop a test to predict VS, and refer only a subset of all patients for MRI.

Objective

To examine the potential savings of such a hypothetical diagnostic test before MRI.

Design

We built a decision analytical model of the diagnostic strategy of VS. Input was derived from literature and key opinion leaders. The current strategy was compared to hypothetical new strategies, assigning MRI to: (1) all patients with pathology, (2) all patients with important pathology and (3) only patients with VS. This resulted in potential cost savings for each strategy. We conducted a budget impact analysis to predict nationwide savings for the Netherlands and the United Kingdom (UK), and a probabilistic sensitivity analysis to address uncertainty.

Results

Mean savings ranged from €256 (95%CI €250 - €262) or approximately US$284 (95%CI US$277 - US$291) per patient for strategy 1 to €293 (95%CI €290 - €296) or approximately US$325 (95%CI US$322 - US$328) per patient for strategy 3. Future diagnostic strategies can cost up to these amounts per patient and still be cost saving. Annually, for the Netherlands €2.8 to €3.2 million could be saved and €10.8 to €12.3 million for the UK.

Conclusions

The model shows that substantial savings could be generated if it is possible to further optimise the diagnosis of VS.

Prophylactic Central Neck Dissection in 68 Patients with Lateral Compartment Metastases from Well Differentiated Thyroid Cancer

Abstract

Skip metastasis (SM) in Well Differentiated Thyroid Cancer (WDTC) patients are lateral neck lymph node metastasis that have skipped the central neck compartment. In these patients, prophylactic central neck dissection remains controversial.

We sought to identify clinicopathological factors associated with SM and determine the accuracy of central neck metastasis imaging in 68 patients at our institution over 16 years.

12 patients (17.6%) had SMs. Compared to the patients with occult central neck metastases, those with SM were more likely to have T1 tumors (p=0.005) and less likely to have extracapsular spread (p=0.032), thyroid capsule extension (p=0.003), soft tissue extension (p=0.006), and multifocal primary tumors (p=0.006).

In assessing the preoperative imaging, we compared central neck dissection pathology reports to the detection rates of CT and ultrasound. We found CT and ultrasound sensitivities of 31.8% and 45%, respectively and specificities of 80% and 85.7%, respectively.

WDTC patients with SM are more likely to have smaller, less aggressive primary tumors. However, the majority (82.4%) had central compartment disease and given the lack of sensitive preoperative imaging, we recommend prophylactic central neck dissections.

Les autobronzants actuellement sur le marché sont pratiquement tous à base de dihydroxyacétone (DHA) associée ou non à l'érythrulose, à des dérivés de tyrosine, parfois à une naphtoquinone. La coloration obtenue, voisine du bronzage naturel, est due à la combinaison chimique de la DHA avec les acides aminés de la peau selon la réaction de Maillard. Il y a formation de mélanoïdines, pigments polymériques, fixés dans le stratum corneum qui y demeurent jusqu'à desquamation des cornéocytes. Cette coloration est donc semi-permanente, bien tolérée par la peau. La formulation des produits est délicate et leur conservation difficile mais aucune autre substance ne fournit de résultats plus satisfaisants et plus durables.Practically all currently available self-tanning products have as their active ingredient dihydroxyacetone (DHA), which may or may not be combined with erythrulose, tyrosine derivatives, and occasionally a naphthoquinone. The resulting skin tone, which resembles a natural tan, is due to chemical combination of the DHA with amino acids in the skin through the Maillard reaction. Polymer pigments known as melanoidins are formed and are fixed in the stratum corneum, where they remain until corneocyte desquamation occurs. The colouring thus achieved is semi-permanent and is well tolerated by skin. While the formulation of such products is complex and their storage difficult, no other substances provide more satisfactory or more lasting results.

Association Between Hypercoagulability and Severe Obstructive Sleep Apnea.

Association Between Hypercoagulability and Severe Obstructive Sleep Apnea.

JAMA Otolaryngol Head Neck Surg. 2017 Aug 17;:

Authors: Hong SN, Yun HC, Yoo JH, Lee SH

Abstract
Importance: Obstructive sleep apnea (OSA) is related to the increased risk of cardiovascular disease. Although the pathogenesis of this association remains unclear, an alteration in coagulability is suspected as a link.
Objective: To investigate the association between the severity of OSA and blood coagulability.
Design, Setting, and Participants: A retrospective cohort study conducted at a tertiary care university hospital evaluated 146 patients with OSA from January 1, 2009, to July 31, 2015. The participants were divided into 4 groups according to the severity of OSA: control, mild, moderate, and severe.
Main Outcomes and Measures: Association between the severity of OSA and coagulation test results, including platelet count, bleeding time, prothrombin time (PT) in seconds and as international normalized ratio (INR), and activated partial thromboplastin time.
Results: Of the 146 patients, 135 (92.5%) were men; mean (SD) age was 34.8 (11.1) years. The control group included 41 (28.1%) patients; mild OSA, 32 (21.9%); moderate OSA, 30 (20.5%); and severe OSA, 43 (29.5%). Significant correlations were found between the apnea-hypopnea index and the PT seconds (Spearman r coefficient, -0.30; 95% CI, -0.44 to -0.14) and PT INR (Spearman r coefficient, -0.30; 95% CI, -0.44 to -0.14). There were significant differences between the OSA severity groups for PT seconds for the control group (mean, 11.26 [0.78] seconds) vs the moderate OSA group (10.74 [0.62] seconds; mean difference [MD], 0.52; 95% CI, 0.27 to 1.01) and the severe OSA group (10.67 [0.77] seconds; MD, 0.59; 95% CI, 0.14 to 1.03). Significant differences were also noted in PT INR between the control group (1.00 [0.07]) vs the moderate OSA group (0.95 [0.05]; MD, 0.04; 95% CI, 0.01 to 0.07) and the severe OSA group (0.94 [0.07]; MD, 0.05; 95% CI, 0.02 to 0.08). However, there was no significant difference between the control and mild OSA groups in PT seconds.
Conclusions and Relevance: These results suggest that patients with moderate to severe OSA have elevated blood coagulability markers compared with healthy individuals, which may contribute to the occurrence of cardiovascular complications.

The "Surgeon on Service" Model for Timely, Economically Viable Inpatient Care of Tracheostomy Patients in Academic Pediatric Otolaryngology.

The "Surgeon on Service" Model for Timely, Economically Viable Inpatient Care of Tracheostomy Patients in Academic Pediatric Otolaryngology.

JAMA Otolaryngol Head Neck Surg. 2017 Aug 17;:

Authors: Lavin JM, Schroeder JW, Thompson DM

Abstract
Importance: The traditional practice model for pediatric otolaryngologists at high-volume academic centers is to simultaneously balance outpatient care responsibilities with those of the inpatient service, emergency department, and ambulatory care clinics. This model leads to challenges with care coordination, timeliness of nonemergency operative care, and consistent participation in care and consultation at the attending surgeon level. The "surgeon on service" (SOS) model-where faculty members rotate to manage the inpatient service in lieu of outpatient responsibilities-has been described as one method to address this conundrum. The operational and economic feasibility of the SOS model has been demonstrated; however, its impact on care coordination, time from consultation to surgical care, and length of stay (LOS) have not been evaluated.
Objective: To determine the impact of the SOS model on the quality principles of timeliness and efficiency of tracheostomy tube placement and to determine if the SOS model is fiscally feasible in an academic pediatric otolaryngology practice.
Design, Setting, and Participants: Medical record review of patients undergoing tracheostomy in a pediatric academic medical center and survey of their treating physician trainees, comparing the 6-month SOS pilot phase (postimplementation, January-June 2016) with the 6-month preimplementation period (January-June 2015).
Intervention: Implementation of the SOS model.
Main Outcomes and Measures: Time to tracheostomy, frequency of successful coordination of tracheostomy with gastrostomy tube placement, total LOS, productivity measured in work relative value units, and responses to trainee surveys.
Results: Of the 41 patients included in the study (24 boys and 17 girls; mean age, 3 years; range, 3 months to 17 years), 15 were treated before SOS implementation, and 26 after. Also included were 21 trainees. Before SOS implementation, median time to tracheostomy was 7 days (range, 2-20 days); after SOS implementation, it was 4 days (range, 1-10 days) (difference between the medians, before to after, -3 days; 95% CI, -5 to 0 days). There was no significant difference in overall LOS or ability to coordinate tracheostomy with gastrostomy tube placement. Preimplementation trainee surveys cited dissatisfaction with the communication channels to the primary team when the consulting surgeon was not immediately available to perform tracheostomy. No challenges were reported after implementation. Productivity was comparable to that in the outpatient setting.
Conclusions and Relevance: In this study, the presence of a rotating inpatient pediatric otolaryngologist was a productive approach to patient care associated with more timely performance of tracheostomy. Other benefits were an improved balance of service with education to trainees and a better perception of communication with consulting services.

Optical Transfer Diagnosis Differentiating Benign and Malignant Pigmented Lesions in a Simulated Primary Care Practice

Abstract

Background

The detection of melanoma poses a substantial challenge, particularly for primary care providers (PCPs) who may have limited training in discriminating between suspicious and benign melanocytic lesions. The noninvasive optical transfer diagnosis (OTD) method was designed to be used by PCPs in their decision-making process.

Objectives

The aim of this clinical study was to assess the potential of the OTD method by developing, training, and validating an OTD indication algorithm for automated discrimination between benign melanocytic lesions and malignant lesions, based on a set of 712 lesions.

Methods

The authors performed in vivo OTD capture and subsequent analysis of 712 pigmented lesions. Of the lesions, 415 were clinically and dermoscopically benign, and 297 were dermoscopically suspicious or equivocal. After image capture, all suspicious or equivocal lesions were biopsied and examined histopathologically.

Results

Of the 297 suspicious or equivocal lesions, histopathologic findings revealed 80 to be malignant (64 melanomas, 13 basal cell carcinomas, and 3 squamous cell carcinomas). OTD misdiagnosed 1 of the 80 malignant lesions as benign (sensitivity, 99%). The OTD specificity was 93% for the dermoscopically benign lesions, 73% for all lesions included in the study, and 36% for the clinically suspicious, but histopathologically benign lesions.

Conclusions

High sensitivity and specificity, as provided by OTD in this preliminary study, would help PCPs reduce the number of referrals for dermatology consultation, excision, or biopsy. Further studies are planned for screening patients in a primary care setting, with comparisons of OTD results to biopsy or dermoscopy results.

Endoscopic characteristics of infection-associated peptic ulcers

Abstract

Background

Aside from Helicobacter pylori, another cause for the development or worsening of gastrointestinal ulcers is scrub typhus, an acute febrile disease caused by Orientia tsutsugamushi. We aimed to compare the endoscopic characteristics of peptic ulcers caused by these infectious agents.

Methods

This retrospective case-control study involved patients who underwent upper gastrointestinal endoscopy at Chosun University Hospital in Korea. We compared endoscopic features and demographic characteristics between patients with H. pylori infection and those with O. tsutsugamushi infection.

Results

A total of 141 patients with peptic ulcer were included in the study. Compared to patients with O. tsutsugamushi infection (n = 62; age, 63.8 ± 12.1 years; male sex, 42%), those with H. pylori infection (n = 79; age, 53.0 ± 14.8 years; male sex, 81%) were younger and more likely to be male (P < .001 for both). Patients with O. tsutsugamushi infection were more likely to have multiple lesions (40/62, 64.5% vs 37/79, 46.8%; P = .042) and irregular-shaped lesions (27/62, 43.6% vs 20/79, 25.3%; P = .031). Patients with H. pylori infection had higher incidence of hemorrhagic ulcers (26/79, 32.9% vs 8/62, 12.9%; P = .007), and lesions occurred most often in the duodenum (43.0%), followed by the antrum (36.7%), body (34.2%), and angle (12.7%) of the stomach. In patients with O. tsutsugamushi infection, lesions occurred most often in the antrum (70.97%), followed by the duodenum (35.5%), body (22.6%), and angle (14.5%) of the stomach. In both groups, gastric ulcer lesions occurred most often in the antrum, followed by the body and angle of the stomach (36.7% vs 70.97%, 34.2% vs 22.6%, and 12.7% vs 14.5% for gastric ulcers associated with H. pylori and O. tsutsugamushi infection, respectively). Patients with O. tsutsugamushi infection had significantly higher incidence of ulcers on the antrum (70.97% vs 36.7%, P < .001) and the greater curvature (45.2% vs 24.0%, P = .012). Finally, 35.5% of patients with gastric ulcer caused by scrub typhus also had duodenal ulcer.

Conclusion

This is the first study to compare endoscopic features of peptic ulcers caused by H. pylori and O. tsutsugamushi. Peptic ulcers in patients with H. pylori infection occurred predominantly in the antrum/body/lesser curvature and presented with single, round/oval lesions, while ulcers in patients with scrub typhus occurred predominantly in the antrum/greater curvature and presented with multiple, irregular lesions. Scrub typhus should be considered as a cause of duodenal ulcer in scrub typhus-endemic areas.

Reliable immunologic biomarkers able to monitor disease course during multiple sclerosis (MS) are still missing. We aimed at identifying possible immunometabolic biomarkers able to predict the clinical outcome in MS patients during treatment with interferon (IFN)-beta-1a. We measured in 45 relapsing-remitting (RR) MS patients, blood circulating levels of several immunometabolic markers, at enrolment, and correlated their levels to disease activity and progression over time. Higher levels of interleukin (IL)-6, soluble-CD40-ligand (sCD40L) and leptin at baseline associated with a higher relapse rate and a greater risk of experiencing at least one relapse in the following year. Higher values of soluble tumor necrosis factor receptor (sTNF-R) and leptin at baseline were predictive of a higher number of lesions in the following one-year of follow up. Our data suggest that an immunometabolic screening measuring IL-6, sCD40L, leptin and sTNF-R at baseline, before starting IFN-beta-1a, is able to predict a poor response to treatment.

Utility and Comparative Efficacy of Recombinant Allergens Versus Allergen Extract

Abstract

Allergy immunotherapy (AIT) is the only disease-modifying therapy for the treatment of allergic diseases. Although its efficacy and utility are well-established, the potential for serious adverse events, cumbersome and lengthy treatment protocols, and variability of natural allergen preparations have limited its widespread application. Recent advances in recombinant technology have opened new avenues for the development of AIT vaccines. The purpose of this review is to highlight recent evidence on the use of novel recombinant vaccines and review the mechanisms, efficacy, safety, and limitations of AIT. Emerging evidence suggests that recombinant vaccines may provide a viable treatment alternative that improves on the limitations of natural extract therapy while maintaining efficacy.

Intelligibility of degraded speech and the relationship between symptoms of inattention, hyperactivity/impulsivity and language impairment in children with suspected auditory processing disorder

S01655876.gif

Publication date: October 2017

Author(s): Ansar Uddin Ahmmed
ObjectivesTo compare the sensitivity and specificity of Auditory Figure Ground sub-tests of the SCAN-3 battery, using signal to noise ratio (SNR) of +8 dB (AFG+8) and 0 dB (AFG0), in identifying auditory processing disorder (APD). A secondary objective was to evaluate any difference in auditory processing (AP) between children with symptoms of inattention versus combined sub-types of Attention Deficit Hyperactivity Disorder (ADHD).MethodsData from 201 children, aged 6 to 16 years (mean: 10 years 6 months, SD: 2 years 8 months), who were assessed for suspected APD were reviewed retrospectively. The outcomes of the SCAN-3 APD test battery, Swanson Nolan and Pelham-IV parental rating (SNAP-IV) and Children's Communication Checklist-2 (CCC-2) were analysed.ResultsAFG0 had a sensitivity of 56.3% and specificity of 100% in identifying children performing poorly in at least two of six SCAN-3 sub-tests or one of the two questionnaires, in contrast to 42.1% and 80% respectively for AFG+8. Impaired AP was mostly associated with symptoms of ADHD and /or language impairment (LI). LI was present in 92.9% of children with ADHD symptoms. Children with symptoms of combined ADHD plus LI performed significantly poorly (p < 0.05) compared to inattention ADHD plus LI in Filtered Words (FW) sub-test, but not in the rest of the SCAN-3 sub-tests.ConclusionSpeech in noise tests using SNR of 0 dB is better than +8 dB in assessing APD. The better FW performance of the inattention ADHD plus LI group can be speculated to be related to known difference in activity in a neural network between different sub-types of ADHD. The findings of the study and existing literature suggest that neural networks connecting the cerebral hemispheres, basal ganglia and cerebellum are involved in APD, ADHD and LI.

Novel molecular defects associated with very early-onset inflammatory bowel.

Purpose of review: Immune dysregulation disorders present with common clinical features of multiorgan autoimmunity. Gastrointestinal involvement is the hallmark of an impaired immune homeostasis. This review will give an overview on the novel phenotypes, highlighting the major points that will help to enable early diagnosis and treatment. Recent findings: The rapid progress on DNA sequencing technologies have led to the identification of monogenic defects that adversely impact the control of immune homeostasis. Lymphocytes may be present but dysfunctional, allowing for the development of excessive autoreactivity and resultant autoimmune disease. Regulatory T cells (Tregs) play an essential role in enforcing immune tolerance. Here we illustrate disorders caused by impairment of mechanisms ensuring Tregs function (Tregs related) in which autoimmunity is a hallmark of the clinical disease presentation and other disorders, affecting molecules more broadly involved in immune responses and indirectly causing immune dysregulation (Tregs unrelated). Clinical presentation is sometime mischievous and often symptoms are analogous in different diseases and can mislead diagnosis. Summary: The increasing comprehension of immunological concepts behind immune dysregulation diseases will allow better and in some cases possibly even targeted treatment. A genetic diagnosis therefore becomes important information in this group of patients, especially as some patients might require hematopoietic stem cell transplantation.

The objective of this study was to investigate the malar bone volume and length that a zygomatic implant can engage, and the relationship to the sinus according to the degree of alveolar bone atrophy. A three-dimensional evaluation was performed using cone beam computed tomography scans from 23 patients with a totally edentulous maxilla; quad zygoma implants were virtually placed. The predictor variable was the amount of malar bone volume and length that a zygomatic implant can engage. The primary outcome variable was the relationship to the sinus according to the degree of alveolar bone atrophy. Other variables were the residual alveolar bone height to the floor of the sinus and the nasal cavity. The mean volume of malar bone engaged in this sample of 92 zygomatic implants was 0.19±0.06cm3. The implant had an extrasinus path in 60.9% of cases, a parasinus path in 25%, and an intrasinus path in 14.1%. The results suggest that the average volume of malar bone engaged by a zygomatic implant is constant regardless of implant position and the degree of alveolar bone atrophy. As alveolar atrophy increases, the trajectory of the implant becomes more parasinus and intrasinus. The examiners were able to find enough bone to adequately distribute the implants in all cases.

This study determined the intra-rater and inter-rater reliability of re-orientating three-dimensional (3D) facial images into the estimated natural head position. Three-dimensional facial images of 15 pre-surgical class III orthognathic patients were obtained and automatically re-orientated into natural head position (RNHP) using a 3D stereophotogrammetry system and in-house software. Six clinicians were asked to estimate the NHP of these patients (ENHP); they re-estimated five randomly selected 3D images after a 2-week interval. The differences in yaw, roll, pitch, and chin position between RNHP and ENHP were measured. For intra-rater reliability, the intra-class correlation coefficient (ICC) values ranged from 0.55 to 0.77, representing moderate reliability for roll, yaw, pitch, and chin position, while for inter-rater reliability, the ICC values ranged from 0.38 to 0.58, indicating poor to moderate reliability. The median difference between ENHP and RNHP was small for roll and yaw, but larger for pitch. There was a tendency for the clinicians to estimate NHP with the chin tipped more posteriorly (6.3±5.2mm) compared to RNHP, reducing the severity of the skeletal deformity in the anterior–posterior direction.

Surgery is the most well established mode of initial definitive treatment for the majority of oral cancers. The most important decision in terms of tumour ablation in oral cancers when the jaws are potentially involved is the management of the mandible. The aim of this study was to explore the differences in survival rate and disease control between patients undergoing marginal mandibulectomy and patients undergoing segmental mandibulectomy using a systematic review and meta-analysis approach. A total of 15 cohort studies, including 1672 participants, were identified. Meta-analysis provided weak evidence in favour of segmental mandibulectomy for local control. Segmental mandibulectomy gave 73% better disease-free survival than marginal mandibulectomy when the marrow was invaded (P=0.04). The overall survival rate was evaluated, and no statistically significant difference was found between the two different mandibulectomy approaches, although the results showed a trend in favour of segmental mandibulectomy which could increase the overall survival by 23%. Based on these findings regarding the survival rate and efficacy of disease control, this study indicates that a marginal mandibulectomy may be recommended for cases with no invasion or superficial invasion of the mandibular cortex, and a segmental mandibulectomy may be a more reasonable choice for patients with extensive mandibular cortex invasion or medullary invasion.

This study re-examined the usefulness of surgery for the management of masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) through a comparison of the outcomes between patients who underwent surgery and those who did not. The duration of follow-up was 2 years. Twenty-eight patients who attended the study hospital and were given a diagnosis of MMTAH were included. Nineteen patients underwent surgery (surgical group) and nine patients were instructed to open their mouths wide once a day and did not undergo surgery (non-surgical group). Maximum mouth opening, impairment of daily activities, satisfaction, and the status of mouth opening training were evaluated after surgery. The mean increase in mouth opening after 2 years was 20.2mm in the surgical group and 2.4mm in the non-surgical group. Adequate mouth opening training led to satisfactory results 2 years postoperative, and sustained mouth opening training for 6 months after surgery was a key factor for obtaining good outcomes. The general condition and personality of individual patients should be evaluated carefully before surgery to estimate whether or not they can endure the pain associated with postoperative mouth opening training. The results of this study suggest that the surgical procedure is useful for the management of MMTAH.

The purpose of the study is to explore the critical parameters determining the visual perception of postoperative facial symmetry. This study retrospectively included 24 patients with skeletal class III malocclusion and double-jaw orthognathic surgery (OgS). The patients were classified according to the outcome of subjective visual perception scores (SVPS) based on the postoperative frontal images by 10 orthodontists: symmetrical surgical outcome (S group, n=12) and facial asymmetry after surgery (A group, n=12). The 3D dentofacial measurements from cone beam computed tomography, were compared between the S and A groups. The relationship of all variables in all patients with the SVPS was explored by Spearman correlation coefficient. Significant differences were observed in the midline parameters in the mandible, the B point, gnathion and menton, and the mandibular border axis as well as in the discrepancy of the chin morphology between the two groups (P<0.05). The findings demonstrated that the midline parameter deviation, shape of the mandibular border, and the contour of menton morphology play the major role in the visual perceptions of postoperative asymmetry.

Inguinal canal spermatic cord leiomyoma presenting as an incarcerated inguinal hernia

Leiomyoma is a benign neoplasm originating from smooth muscle cells and is most commonly seen in the uterus, followed by the small bowel and oesophagus. We report a rare case of a 41-year-old male patient with a spermatic cord leiomyoma that presented as an inguinal canal mass mimicking an irreducible inguinal hernia without scrotal involvement. This report highlights the rare presentation and workup of an inguinal mass, importance of intraoperative decision making based on operative findings and the significance of postoperative pathology findings.

Hypersegmented neutrophils and oval macrocytes in the setting of B12 deficiency and pancytopaenia

Vitamin B12 deficiency is a recognised pathology in several populations, with a particular prevalence in an older adult population. We present two cases whereby vitamin B12 deficiency is the causative factor in marked pancytopaenia. Oval macrocytosis and hypersegmented neutrophils were noted on both peripheral blood samples, which are a characteristic finding in macrocytic anaemia due to B12 deficiency. Distinct underlying pathologies were identified in both cases; food-cobalamin malabsorption and pernicious anaemia. Parenteral vitamin B12 supplementation resulted in a marked reticulocytosis and rapid improvement of haematological indices in both cases. We present this series to serve as a reminder that B12 deficiency can present as life-threatening pancytopaenia.It has has multiple underlying pathologies,defined risk populations and has characteristic blood film findings which can guide investigations, diagnosis and treatment.

Mega-giant coronary aneurysm: antithrombotic therapy is an option

A 69-year-old man with a history of hypercholesterolaemia presented to the emergency department with atypical chest pain. Physical examination was normal and ECG showed no evidence of ischaemic changes. Laboratory studies were notable for a D-dimer level of 1842 ng/mL (reference value <500 ng/mL) and the troponin I level was normal.

Chest X-ray was normal. Chest CT angiography ruled out a pulmonary embolism but showed a giant and extensive aneurysm of the right coronary artery (RCA) up to 45 mm in diameter with a partly thrombosed lumen and evidence of right ventricle compression on four-chamber view (figures 1 and 2). The volume of the aorta and the RCA appeared similar (figure 3). Doppler echocardiography did not demonstrate right or left heart haemodynamic abnormalities.
