Leila Ferguson, L Claire Fuller
Tinea capitis is the most important superficial fungal condition in children. It is often unrecognised but the presence of alopecia, scale and lymphadenopathy, especially in inner-city children should prompt investigation. An understanding of changing epidemiology and prevalence of causative organisms is important in deciding appropriate therapy. The use of diagnostic aids including dermoscopy is increasing and is reported to be helpful in identifying subtle signs. Trichophyton tonsurans accounts for the majority of cases in the UK and terbinafine is increasingly advocated as a safe and effective therapy...

INTRODUCTION: Several recent trials have reported limited benefit for medical expulsive therapy (MET) in terms of stone passage rates, analgesic requirements, or need for intervention. We evaluated patient attitudes regarding MET after explaining these new findings. MATERIALS AND METHODS: Over a 12 week period, an investigator-designed survey was offered to sequential patients during routine appointments in our urologic clinic. A brief summary of the conflicting data for MET was provided...

BACKGROUND: Haematuria and pelvic pain are recognized and documented adverse reactions related to Cabazitaxel use. To date there has not been any documentation of imaging findings in patients with this presentation. CASES: We report a case series of five patients who experienced these symptoms while on Cabazitaxel and were all found to have very similar urothelial changes on CT. The patients were noted to have ureteric and renal pelvic dilatation along with urothelial enhancement (in those who had post contrast imaging)...

The aim of this study is to investigate the relationship between the risk of muscle dysmorphia and psychopathological symptoms in an Italian sample of male bodybuilders. METHOD: The sample was recruited online (145 men with a mean age of 30.0 years) and participants were asked to fill out the Muscle Dysmorphic Disorder Inventory (MDDI), Symptom Cheklist-90-R (SCL-90-R), Dissociative Experiences Scale (DES-II), and to provide other socio-demographic data. Bodybuilders at risk of muscle dysmorphia display greater global psychopathology and present higher scores on all SCL-90-R dimensions when compared to bodybuilders not at risk of muscle dysmorphia...

Three series of H2S donors based on NSAIDs were synthesized and characterized by (1)H-NMR, IR and ESI-HRMS. The H2S-release abilities of all compounds were evaluated in the presence of TECP or cysteine. The results show all compounds were fast H2S-releasers, and their half-lives were in range of 0-20 min. Under the same condition, H2S released from compound 9 was more than any other compounds. In cytotoxicity aspect, all compounds but 1 and 2 displayed much lower toxicities to both LO2 and HepG2 cell lines, and the IC50 values of most compounds were over 800 μM...

REVIEW
Peter Mundel
In this review, I describe a 30-year journey in the quest for precision medicines for patients with kidney diseases. In 1987, when I started my reseach career, most scientists studying glomerular disease biology were focused on mesangial cells. The crucial role of the podocyte in many kidney diseases characterized by proteinuria, including focal segmental glomerulosclerosis (FSGS) and diabetic nephropathy, had not yet been recognized. We were not aware of genetic causes or drivers of kidney diseases nor of molecular markers and cell culture systems for mechanistic studies of podocyte biology...

The Smilax species, widely distributed in tropical region of the world and the warm areas of East Asia and North America, are extensively used as folk medicine to treat inflammatory disorders. Chemical investigation on Smilax species showed they are rich sources of steroidal saponins with diversified structure types, including spirostane, isospirostane, furostane, pregnane, and cholestane. This review mainly summarizes the steroidal saponins (1-104) reported from the genus Smilax between 1967 and 2016, and their biological activities...

The principle steroidal androgens are testosterone and its metabolite 5α-dihydrotestosterone (DHT), which is converted from testosterone by the enzyme 5α-reductase. Through the classic pathway with androgens crossing the plasma membrane and binding to the androgen receptor (AR) or via mechanisms independent of the ligand-dependent transactivation function of nuclear receptors, testosterone induces genomic and non-genomic effects respectively. AR is widely distributed in several tissues, including vascular endothelial and smooth muscle cells...

We have investigated gross pathology, physiological (steroid precursors) and toxicological responses (oxidative stress and phase II biotransformation) in relation to tissue contaminant burden in Tilapia species along the entire length (320 km) of Ogun River, Nigeria. The Ogun River is the longest and largest river in Southwestern Nigeria located along heavily industrialized cities and receives complex mixtures of effluents. A total of 1074 tilapias were collected from three sampling points (Abeokuta, Isheri and Ikorodu) and from an upstream control point (Igboho) and evaluated for gross pathological changes, hepatic transcript levels for oxidative stress and phase II biotransformation responses...

Sterol regulatory element binding proteins (SREBPs) are transcriptional regulators of lipids which promote glioblastoma growth. Here, we investigate the effect of inhibiting expression of SREBP target genes in human glioblastoma cells. This was achieved by using PF-429242 to inhibit site-1 protease (S1P), an enzyme required for SREBP activation. Treatment with PF-429242 decreased glioblastoma cell viability, induced apoptosis and downregulated steroid, isoprenoid and unsaturated fatty acid biosynthetic pathways...

We have shown Bisphenol A (BPA) acts as an androgen receptor (AR) antagonist in the previous study. However, the mechanisms underlying anti-androgenic effects of BPA remain unclear. The objective of this study was to explore whether the AR signaling was involved in AR antagonism of BPA. The Cell Counting Kit-8 (CCK-8) assay and Real-Time Cell Analysis (RTCA) iCELLigence system were applied to analyze the mouse Sertoli cell TM4 proliferation. The mammalian two-hybrid assays were performed to investigate the effects of BPA on the AR amino- and carboxyl-terminal regions (N/C) interaction and the interactions of the AR with steroid receptor coactivator-1 (SRC-1), co-repressors including silencing mediator for thyroid hormone receptors (SMRT) and nuclear receptor co-repressor (NCoR)...

Steroid resistance syndrome (mineralocorticoids, glucocorticoids, estrogens, androgens) is a rare clinical disorder, androgen insensitivity syndrome being the most commonly described. Resistance syndromes are characterized by elevated steroid hormone levels, secondary to an impaired signal transduction and a lack of negative feedback, without any specific clinical signs of steroid excess. In most cases, steroid hormone resistance is generally caused by steroid receptor mutations. Several nonsense and missense mutations or deletions have already been described for all steroid receptors, except for the progesterone receptor...

BACKGROUND: Intraocular involvement of systemic T-cell lymphomas are uncommon and have been broadly regarded as markers of poor prognosis. We reported two cases of uveitis patients finally diagnosed as systemic T cell lymphoma. CASE PRESENTATION: Case one is a 19-year-old female presented with fever and liver dysfunction, and was diagnosed as EBV-associated chronic active hepatitis. Fourteen months later, she suffered from recurrent granulomatous anterior uveitis in both eyes, which failed to respond to steroid and immunosuppressant therapy...

BACKGROUND: Anti-TNF agents have demonstrated to greatly improve management strategies for inflammatory bowel disease (IBD). Clinical trials and registry studies in Western countries have shown that infections and malignancy are the most concerned complications of anti-TNF treatment. However, data derived from clinical practice in China are limited. The aim of this study is to explore the long-term infection risk of infliximab (IFX) in treating patients with Crohn's disease (CD) from a tertiary IBD center in China...

Over the past decades eosinophilic esophagitis (EoE) has been increasingly diagnosed, and significant progress has been made in our understanding of its pathophysiology. As EoE cannot be cured yet, treatment goals are suppression of disease activity and symptoms as well as the prevention of progression to a more severe disease phenotype. Disease-modifying treatment options can be divided into dietary therapy and immunosuppressive medications, of which topical steroids have been most investigated, yet are still prescribed off-label...

Despite medical advances, pneumonia is a leading cause of death worldwide. Because inflammation is a key defense mechanism, adjuvant corticosteroid therapy has long been considered but never widely recommended to treat pneumonia. New research is exploring potential benefits of this therapy, including reduced time to clinical stability, reduced hospital stay, reduced rates of treatment failure, and prevention of complications.

A 55-year-old nurse was referred with a 5-month history of right eye corneal abscess. The initial injury occurred when doing lawn work. The infection worsened despite multiple antibiotic, antiviral, and steroid treatments. Visual acuity was limited to hand motion. On examination, there was keratitis, ocular hypertension, and a secondary cataract. Corneal scrapings grew a filamentous fungus, identified as Metarhizium anisopliae (MA). Despite intensive antifungal treatment with topical, intravitreous, and systemic voriconazole, purulent corneal melting and scleritis with endophthalmitis rapidly appeared...

Rice bran (RB) consumption has been shown to reduce colorectal cancer (CRC) growth in mice and modify the human stool microbiome. Changes in host and microbial metabolism induced by RB consumption was hypothesised to modulate the stool metabolite profile in favour of promoting gut health and inhibiting CRC growth. The objective was to integrate gut microbial metabolite profiles and identify metabolic pathway networks for CRC chemoprevention using non-targeted metabolomics. In all, nineteen CRC survivors participated in a parallel randomised controlled dietary intervention trial that included daily consumption of study-provided foods with heat-stabilised RB (30 g/d) or no additional ingredient (control)...
