#1
Ranjit G Gurav, Jingchun Tang, Jyoti P Jadhav
In black feathers, melanin is embedded in keratin matrix that makes feather more resistance to the microbial degradation. Chryseobacterium sp. RBT previously isolated from the poultry waste disposable site revealed strong sulfitolytic and keratinolytic activities. Maximum keratinase activity was observed at 48 h (89.12 U ml(-1)) showed 83 % of native black feather degradation. The concentration of free sulfhydryl groups released during degradation was 0.648 × 10(-4) M (12 h), 2.144 × 10(-4) M (96 h), and however, declined on prolong incubation to 1...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening disorders. The incidences, mortality and cost of SJS and TEN in US adults are not well-characterized. We analyzed data from the 2009-2012 Nationwide Inpatient Sample, containing a representative 20% sample of all hospitalizations in the US. SJS, SJS/TEN and TEN were identified by a validated algorithm using ICD-9- CM codes. The mean incidences of SJS, SJS/TEN and TEN were 9.3, 1.6, and 1.9 per million people per year, respectively...

Psoriasis is a chronic inflammatory skin disorder associated with substantial morbidity and mortality. Little is known about psoriasis in the inpatient setting. We sought to determine the inpatient burden of psoriasis in the US. We analyzed the 2002-2012 Nationwide Inpatient Sample, containing a representative 20% stratified sample of all hospitalizations in the US. Psoriasis was determined by a validated algorithm using ICD-9-CM codes. Demographics, inflation-adjusted cost, length of stay, comorbidities, and sex- adjusted mortality were analyzed using descriptive statistics and regression analysis...

People of color are at significantly higher risk in mortality from skin cancers, such as melanoma, than Caucasians. Around 4,500,000 people of color are affected by skin cancer The five-year survival rates from melanoma are 81.1% for Hispanics, 80.2% for Asians, 72.2% for African- Americans, and 89.6% for Caucasians. For this reason, it is important to ensure the scientific literature reflects the most up to date recommendations and treatment for blacks regarding skin cancer. Therefore the authors conducted a "gap analysis" on the current treatment of skin cancer in people of color...

Nevus comedonicus is considered a genodermatosis characterized by the presence of multiple groups of dilated pilosebaceous orifices filled with black keratin plugs, with sharply unilateral distribution mostly on the face, neck, trunk, upper arms. Lesions can appear at any age, frequently before the age of 10 years, but they are usually present at birth. We present a 2.7-year-old girl with a very severe form of nevus comedonicus. She exhibited lesions located initially at the left side of the body with a linear characteristic, following Blascko lines T1/T2, T5, T7, S1 /S2, but progressively developed lesions on the right side of the scalp and left gluteal area...

BackgroundLocalized cutaneous argyria is a rare skin condition caused by direct contact with silver or silver particles. It presents as asymptomatic gray or blue-gray macules that appear similar to blue nevi. Histologic features include brown-colored or black-colored silver granules in the basement membrane and dermis, most commonly surrounding eccrine glands, elastic fibers, and collagen fibrils. The condition is most frequently observed in individuals who are regularly exposed to small silver particles, such as silversmiths and welders...

OBJECTIVE: This study investigated racial disparity in life expectancies (LEs) and life years lost (LYL) associated with multiple obesity-related chronic conditions (OCCs). METHODS: Data from the Medical Expenditure Panel Survey, 2008-2012, were used. Four OCCs were studied: diabetes, hypertension, coronary heart disease (CHD), and stroke. LE for each subpopulation was simulated by Markov modelling. LYL associated with a disease for a subpopulation was computed by taking the difference between LEs for members of that subpopulation without disease and LEs for members of that subpopulation who had that disease...

Study Objectives: Emerging evidence suggests that periodic limb movements (PLMs) may contribute to the development of cerebrovascular disease. White matter hyperintensities (WMHs), a widely accepted biomarker for cerebral small vessel disease, are associated with incident stroke and death. We evaluated the association between increased PLM indices and WMH burden in patients presenting with stroke or transient ischemic attack (TIA), while controlling for vascular risk factors and stroke severity...

Importance: Chronic actinic dermatitis (CAD) is classically described in older, white men, although increasing reports describe younger patients with darker skin types, particularly South Asians. Photocontact allergy occurs in CAD but is less studied than contact allergy in this exquisitely photosensitive condition. Objective: To evaluate for differences in demographic and photobiological features between persons with darker and lighter skin types who have CAD. Design, Setting, and Participants: This retrospective review included 70 consecutive adult patients (≥18 years) undergoing investigation for photosensitivity who were diagnosed with CAD from November 1, 2000, through August 31, 2015, at the specialist Photobiology Unit of a tertiary academic referral center...
