REVIEW
Philip R Cohen
Basal cell carcinoma of the buttock is rare, and only 28 patients have been described. An extensive literature search was performed on basal cell carcinoma and buttock using the PubMed database. The literature was evaluated, and the characteristics of individuals with basal cell carcinoma of the buttock were summarized. The calculated prevalence of basal cell carcinoma of the buttock was 0.35%. The majority of patients had no obvious basal cell carcinoma-associated risk factors. Carcinomas were observed 1.2 times more often in women than in men, and more often on the right buttock...

OBJECTIVES: Transient hyperthyroidism has been documented following surgical manipulation or direct trauma to the normal thyroid gland. This has best been studied in patients following parathyroidectomy and also reported following trauma to the neck, strangulation, and vigorous palpation of the thyroid gland. It has not previously been reported following a thyroid ultrasound. METHODS: We report the case of a 58-year-old euthyroid woman with a large nontoxic multinodular goiter who developed transient hyperthyroidism following an ultrasound of the thyroid gland...

BACKGROUND: Juvenile pilocytic astrocytomas represent the largest group of pediatric brain tumors. The ideal management for these tumors is early, total surgical resection. To detect and track treatment response, a screening tool is needed to identify patients for surgical evaluation and assess the quality of treatment. The identification of aberrant miRNA profiles in the sera of juvenile pilocytic astrocytoma patients could provide such a screening tool. METHODS: The authors reviewed the serum profiles of 84 oncologically relevant miRNAs in pediatric juvenile pilocytic astrocytoma patients via qPCR screening...

In recent years, with an increasing number of central venous access procedures and cardiac implantable electronic device implantation, the incidence of infective endocarditis (IE) has become more prevalent. Two-dimensional transthoracic echocardiography (2D-TTE) and transesophageal echocardiography (TEE) are a key part of the evaluation of IE, but advances in three-dimensional echocardiography have enabled a better spatial resolution and visualization of cardiac structures, allowing the identification of any valvular vegetations, abscesses, or nodules...

Secondary multidrug transporters of the resistance-nodulation-cell division (RND) superfamily contribute crucially to antibiotic resistance in Gram-negative bacteria. Compared to the most studied transporter AcrB of Escherichia coli , little is known about the molecular determinants of distinct polyspecificities of the most important RND transporters MexB and MexY of Pseudomonas aeruginosa . In an effort to add knowledge on this topic, we performed an exhaustive atomic-level comparison of the main putative recognition sites (access and deep binding pockets) in these two Mex transporters...

INTRODUCTION: The management of posterior deep endometriosis is not consensual. This is due to a great heterogeneity of data from the literature. Many series were small and overall, predictors of pregnancy were not all included and analyzed by multivariate analysis. We conducted this study to evaluate the factors associated with pregnancy during the first two in vitro fertilization (IVF) attempts in infertile women with posterior deep endometriosis. MATERIAL AND METHODS: 230 women were included in this retrospective observational study, between January 1th, 2007 and September 30th, 2013, at the University Hospital of Lille...

A male in his twenties presented with a tender finger nodule that had been present for 3 months. Histopathological examination revealed a dermis with nodules of necrotic, athypical epithelaia cells with high nuclear to cytoplasmic ratios. Glandular formation was present with lumens lined by columnar epithelium, consistent with digital papillary adenocarcinoma. Digital papilary adenocarcinoma is a rare malignant adnexal tumor arising from sweat glands and requires further work-up.
