Background: The primary objective of this study was to ascertain the benefit of Vicco turmeric Ayurvedic cream (VTC; Vicco Laboratories, Mumbai, India) sandalwood oil and turmeric-based cream in preventing radiodermatitis in women undergoing curative radiotherapy for their breast cancer. Methods and Materials: The study was an investigator-blinded randomized study with Johnsons Baby Oil (JBO; John...

Inhibition of Lymphatic Drainage With a Self-Designed Surgical Approach Prolongs the Vascularized Skin Allograft Survival in Rats.

Vascularized composite allotransplantation (VCA) is an emerging treatment for significant tissue defects. However, VCAs usually consist of multiple highly antigenic skin tissues. Previous studies have shown that the lymphatic system in skin plays important roles in the initiation of immune responses during acute rejection, by transporting T cells and antigen-presenting dendritic cells to regional ...

Clinical and Confocal Microscopy Study of Plasma Exeresis for Nonsurgical Blepharoplasty of the Upper Eyelid: A Pilot Study.

Plasma exeresis is an evolving technique for nonsurgical treatment of several skin conditions. Reflectance confocal microscopy (RCM) is a noninvasive tool that allows the "in vivo" imaging of the skin.

Newborn skin reflection: Proof of concept for a new approach for predicting gestational age at birth. A cross-sectional study.

Current methods to assess the gestational age during prenatal care or at birth are a global challenge. Disadvantages, such as low accessibility, high costs, and imprecision of clinical tests and ultrasonography measurements, may compromise health decisions at birth, based on the gestational age. Newborns' organs and tissues can indirectly indicate their physical maturity, and we hypothesized that ...

Effect of topical application of black seed oil on imiquimod-induced psoriasis-like lesions in the thin skin of adult male albino rats.

Psoriasis is a chronic inflammatory skin disease that affects about 1-3% of the world's population. Black seed oil, i.e the oil extracted from black seeds (Nigella sativa seeds), possesses a broad spectrum of pharmacological actions including anti-inflammatory, immunostimulatory and antioxidant properties. This study aimed to investigate the effect of black seed oil on imiquimod (IMQ) induced psor...

Progressive Elbow Contracture and Skin Thickening Due to Dystrophic Calcification.

Ontogeny and function of murine epidermal Langerhans cells.

Langerhans cells (LCs) are epidermis-resident antigen-presenting cells that share a common ontogeny with macrophages but function as dendritic cells (DCs). Their development, recruitment and retention in the epidermis is orchestrated by interactions with keratinocytes through multiple mechanisms. LC and dermal DC subsets often show functional redundancy, but LCs are required for specific types of ...

Utility of abdominal skin plus subcutaneous fat and rectal mucosal biopsy in the diagnosis of AL amyloidosis with renal involvement.

Skin fat biopsy of the abdominal wall is a simple and safe method for detecting amyloidosis, and rectal mucosal biopsy is also frequently used for screening for the disease; however, the sensitivity of these approaches has not been fully studied. The aim of this study was to evaluate the efficacy of skin fat biopsy combined with rectal mucosal biopsy as a screening procedure for the diagnosis of s...

Role of inducible nitric oxide synthase and interleukin-6 expression in estimation of skin burn age and vitality.

Estimation of age and vitality of burn injury both in the living and dead is essential in forensic practice. Nitric oxide and interleukin-6 (IL-6) play an important role in skin burn healing. In this study, the expression of inducible nitric oxide synthase (iNOS) and IL-6 proteins during skin burn healing in rats was studied for purposes of burn dating and to differentiate between ante-mortem and ...

Exome sequencing identifies a TCF4 mutation in a Chinese pedigree with symmetrical acral keratoderma.

Symmetrical acral keratoderma (SAK) is a rare skin disorder and its pathogenesis and inheritability are unknown.

Effect of prophylactic cefalexin treatment on the development of bacterial infection in acute radiation-induced dermatitis in dogs: a blinded randomized controlled prospective clinical trial.

Acute radiation-induced dermatitis (ARID) is a common sequela of radiation therapy and carries the risk of secondary bacterial skin infection. No standard of care exists for managing canine ARID and evidence-based guidelines are lacking; however, prophylactic use of antibiotics is common.

Growing evidence of the beneficial effects of a marine protein-based dietary supplement for treating hair loss.

Hair loss is a common condition among women with a range of causes including nutritional deficiencies.

Blisters, ulcers, crusts, and atrophic scars on the back of the hands and the extensor aspects of the forearms.

Viral reactivation imitates relapse of pemphigus vulgaris in an immunosuppressed patient.

Symmetrical hyperpigmentation of the forehead in a 37-year-old female patient from Guinea, West Africa.

Disruption of human stratum corneum lipid structure by sodium dodecyl sulfate.

Surfactants are major ingredients of body soaps and cleansers. Among them, harsh ones have been demonstrated to damage the skin. Stratum corneum (SC), the outermost barrier of skin layer, is rich in intercellular lipids. This lipid structure can be disrupted by surfactants, impairing the barrier function of the skin. Thus, we investigated the surfactant-induced disruption of the intercellular lipi...

Dactylitis in sarcoidosis.

Accelerated Epithelialization and Improved Wound Healing Metrics in Porcine Full-Thickness Wounds Transplanted with Full-Thickness Skin Micrografts.

Split-thickness skin grafting (STSG) is the current gold standard for treatment of extensive burn and traumatic skin injuries. However, STSG is limited by donor-site morbidity and availability, and often leads to scarring and wound contracture. Furthermore, these thin grafts lack dermal elements such as nerves and adnexa which are important in recapitulating normal skin function. Methods of fracti...

Effects of collagen peptides intake on skin ageing and platelet release in chronologically aged mice revealed by cytokine array analysis.

Action mechanisms underlying various biological activities of collagen peptides (CPs) remained to be elucidated. Cytokines may play an important role in mediating these health benefits of CPs. This study aimed to systemically examine the cytokines in skin and blood regulated by CPs intake. Thirteen-month-old female Kunming mice were administered with CPs for 2 months (0 or 400 mg/kg bodyweight/d...

Scanning electron microscopy and histopathological observations of Beauveria bassiana infection of Colorado potato beetle larvae.

Beauveria bassiana is a potential candidate for use as an environmentally friendly bio-pesticide. We studied the infection process and histopathology of B. bassiana strain NDBJJ-BFG infection of the Colorado potato beetle (Leptinotarsa decemlineata) using scanning electron microscopy and hematoxylin-eosin staining of tissue sections. The results show that the fungus penetrated the insect epidermis...

Skin Regeneration Effect of the Glycosaminoglycans from Liparis tessellatus eggs.

A purified Glycosaminoglycans (GAGs) extract from L. tessellatus eggs was enzyme-hydrolyzed and then fractionated with DEAE-Sepharose column chromatography. The fractions were subsequently subjected to skin regeneration effects analysis against skin fibroblast (CCD-986sk) cell lines. Fraction 3 is evidently to have tyrosinase inhibition activity by 20.1% at concentration of 50mg/mL. DOPA oxidation...

Glycerosomes: investigation of role of 1,2-dimyristoyl-sn-glycero-3-phosphatidycholine (DMPC) on the assembling and skin delivery performances.

Glycerosomes were formulated using 1,2-dimyristoyl-sn-glycero-3-phosphatidycholine (DMPC), diclofenac sodium salt and 10, 20 or 30% glycerol in the water phase, while corresponding liposomes were prepared with the same amount of DMPC and diclofenac, without glycerol. The aim of the present work was to evaluate the effect of the used phospholipid on vesicle features and ability to favour diclofenac...

Primary photosensitization and contact dermatitis caused by Malachra fasciata Jacq. N.V. (Malvaceae) in sheep.

Farmers from Paraiba state, Northeast Brazil, claim that Malachra fasciata causes cutaneous lesions in sheep. To test its toxicity the plant was harvested daily and fed ad libitum for 21 days to 3 sheep as the sole food source (# 1-3). An additional sheep (# 4) was maintained as a control. Cutaneous lesions of photosensitization initiated after 7 days and increased continuously over the next 21 da...
