There is increasing evidence supporting the use of corticotropin as an alternative treatment of refractory proteinuric glomerulopathies. The efficacy of short-acting corticotropin, however, remains unknown and was tested here in an adolescent with steroid-dependent nephrotic syndrome caused by minimal change disease. After developing Cushing syndrome and recently being afflicted with severe cellulitis, the patient was weaned off all immunosuppressants, including corticosteroids. This resulted in a relapse of generalized anasarca, associated with massive proteinuria and hypoalbuminemia...

Percutaneous titanium implants for bone conduction devices (BCDs) have offered, since 1977, a solution for patients with hearing loss not treatable by conventional hearing aids, such as patients with chronic ear infections or microtia and/or ear canal atresia. Percutaneous implants imply a continuous breach in the mechanical defensive barrier of the skin. To compensate for this breach, immunological mechanisms in the subcutaneous tissue surrounding the implant become more active. This article is protected by copyright...

Medical photography, and in particular dermatological imagery, is often assumed to provide an objective, and functional, representation of disease and that it can act as a diagnostic aid. By contrast, artistic conceptions of the images of the body tend to focus on interpretative heterogeneity and ambiguity, aiming to create or explore meaning rather than enact a particular function. In her 2015 retrospective exhibition at the Tate Modern, South African artist Marlene Dumas questions these disciplinary divides by using medical imagery (among other photographic sources) as the basis for her portraits...

BACKGROUND: Polycystic ovary syndrome (PCOS) is a very common disorder well known to be associated with insulin resistance and metabolic disease. Insulin resistance is likely involved in the promotion of the PCOS reproductive phenotype and may mediate some of the ovarian morphology seen in the disorder. The phenotype of each individual woman with PCOS can vary widely as can her metabolic risk. METHODS: This is a cross-sectional study of patients seen in a multidisciplinary PCOS clinic at the University of California at San Francisco between 2006 and 2014...

OBJECTIVE: Viral oral ulcers are common presentations in pediatric clinics. Although self-limiting, painful ulcerative lesions and inflamed mucosa can decrease oral intake and lead to dehydration. Despite the widespread use of Chinese herbal medicine (CHM) for pediatric upper respiratory disease in Taiwan, there is little evidence for its effectiveness as an antipyretic or in aiding ulcer healing for children with viral oral ulcers. We report two cases of children who presented with viral oral ulcers to illustrate the potential efficacy of CHM treatment in recovery from herpangina (HA) and herpetic gingivostomatitis (HGS)...

Intradermal delivery of antigens for vaccination is a very attractive approach since the skin provides a rich network of antigen presenting cells, which aid in stimulating an immune response. Numerous intradermal techniques have been developed to enhance penetration across the skin. However, these methods are invasive and/or affect the skin integrity. Hence, our group has devised zinc oxide (ZnO) nano-rods for non-destructive drug delivery. Chemical vapour deposition was used to fabricate aligned nano-rods on ZnO pre-coated silicon chips...

Tuberculosis (TB) in persons living with HIV (PLHIV) is the leading infectious cause of AIDS-related death. The aim of this study was to estimate the prevalence of TB/HIV coinfection, evaluate notification of the two diseases over time by probabilistic database linkage, and identify factors associated with AIDS and TB notifications. Prevalence of TB/HIV coinfection was 7.7%. The group of PLHIV with subsequent TB diagnosis was the most representative, despite available preventive measures. Underreporting of TB among AIDS cases was 35%, and 19...

Atopic dermatitis is a chronic inflammatory skin condition affecting both children and adults and is associated with pruritus. A method for objectively quantifying nocturnal scratching events could aid in the development of therapies for atopic dermatitis and other pruritic disorders. High-resolution wrist actigraphy (3-D accelerometer sensors sampled at 20 Hz) is a non-invasive method to record movement. This work presents an algorithm to detect nocturnal scratching events based on actigraphy data. The twofold process consists of segmenting the data into "no motion", "single handed motion" and "both handed motion" followed by discriminating motion segments into scratching and other motion using a bi-directional recurrent neural network classifier...

Wearable photoplethysmogram (PPG) sensors offer convenient and informative measurements for evaluating daily physiological states of individuals. In this work, epidermal and flexible near-infrared (NIR) PPG sensors integrating a low-power, high-sensitivity organic phototransistor (OPT) with a high-efficiency inorganic light-emitting diode are developed. By exploiting an organic bulk heterojunction active layer and a bilayer gate dielectric design, a low voltage (<3 V) operated OPT with NIR responsivity as high as 3...

Coccidioidomycosis (CM) is a fungal infection endemic in southwestern regions of the United States, northwestern regions of Mexico, and some areas of Brazil and Argentina. Clinical presentation varies depending on the extent of the infection and the immune status of the host. The most common presentation ranges from flu-like symptoms to self-limiting pneumonia. Extrapulmonary presentations are uncommon and may involve the meninges, skin, and bone. Gastrointestinal and peritoneal involvement is extremely rare...

Clothing modifies ultraviolet radiation exposure from the sun, and has an impact on skin cancer risk and the endogenous synthesis of vitamin D3 . There is no standardized method available for assessing body surface area covered by clothing, which limits generalizability between study findings. We calculated the body cover provided by 38 clothing items using diagrams of body surface area (BSA), adjusting the values to account for differences in BSA by age. Diagrams displaying each clothing item were developed and incorporated into a coverage assessment procedure (CAP)...

Breast and pectoral muscle segmentation is an essential pre-processing step for the subsequent processes in computer aided diagnosis (CAD) systems. Estimating the breast and pectoral boundaries is a difficult task especially in mammograms due to artifacts, homogeneity between the pectoral and breast regions, and low contrast along the skin-air boundary. In this paper, a breast boundary and pectoral muscle segmentation method in mammograms is proposed. For breast boundary estimation, we determine the initial breast boundary via thresholding and employ Active Contour Models without edges to search for the actual boundary...

OBJECTIVE: Protein energy wasting is difficult to assess in pediatric hemodialysis (HD) populations because of fluid shifts. Body composition (BC) analysis aids in monitoring nutrition therapy's effects on fat and lean mass. Air displacement plethysmography (ADP) is a "practical" gold standard for fat mass (FM) measurements. We aim to compare BC measures in a pediatric HD population via anthropometry, ADP, and bioelectrical impedance (BIA). DESIGN: The study was prospective cohort study and the setting was 1 pediatric HD unit in Houston, Texas...

REVIEW
Willem Takken, Niels O Verhulst
Anthropophilic mosquitoes use host-derived volatile compounds for host seeking. Recently it has become evident that many of these compounds are of microbial origin. Host seeking of mosquitoes is, therefore, a tritrophic relationship and suggests co-evolution between blood hosts and their microbial community to the benefit of the mosquito. Chemical analysis of bacterial headspace resulted in discovery of several compounds that make up the attractive blend to which mosquitoes respond. Future studies should determine which host factors shape the skin microbial community and attractive volatiles produced...
