Formaldehyde (FHO) is a multipurpose chemical that is an eye, nose, throat and skin irritant, sensitizer and allergen, as well as a class 1 human carcinogen. Brazilian hair treatments, containing high levels of FHO (up to 11%), have become regularly used that have the potential to expose clients to toxic levels in excess of current regulatory standards. We report on a patient who underwent a si...

Allergic contact dermatitis (ACD) is the most prevalent form of immunotoxicity in humans characterized by clinical manifestations such as red rashes, itchy skin and blisters. The disease is caused by skin sensitizers which are allergenic low-molecular weight chemicals. ACD is an important occupational disease that gives problems at different workplaces, including hair dressers, metal workers, c...

this is a report of a very rare case of recurrent subclitoral abscess. its etiology and the best treatment of the disease is here in discussed. we, the same as sur, believe that marsupialization is the most promising treatment. recurrent periclitoral abscess has been described previously5. s ome of the authors believe that it is part of the pilonidal disease. the first pilonidal cyst in 7 the c...

pilonidal disease consists of a hair-containing sinus or abscess occurring most frequently in intergluteal cleft. this disease is generally benign. although very uncommon entity, it seems reasonable to be aware of possible malignancy in longstanding cases. we report a case of squamous cell carcinoma in a 52- year-old man, with a prolonged history of pilonidal disease and ulceration since 3 mont...

Alopecia areata is a frequent cause of hair loss. The origin of disease is not fully understood. However there are indications for a T-cell mediated autoimmune process. Genetic, immunologic and psychologic factors are important for the outbreak of disease. Most patients show localized patches of acute hair loss, where regrowth is observed spontaneously or with simple topical treatment within fe...

Alopecia areata is among the most prevalent autoimmune diseases, yet compared with other autoimmune conditions, it is not well studied. This in part results from limitations in the C3H/HeJ mouse and DEBR rat model systems most commonly used to study the disease, which display a low frequency and late onset. We describe a novel high-incidence model for spontaneous alopecia areata. The 1MOG244 T ...

Alopecia areata incognita, also known as diffuse alopecia areata, is a rare form of alopecia areata described predominantly in young women. In cases of alopecia areata incognita, the typical patchy distribution of hair loss in classical alopecia areata is absent, but abrupt and intense hair loss is characteristic. While the clinical picture presented by this disease closely resembles that of te...

Background: The seladin-1 (selective Alzheimer disease indicator-1), also known as DHCR24, is a gene found to be down-regulated in brain region affected by Alzheimer disease (AD). Whereas, hair follicle stem cells (HFSC), which are affected in with neurogenic potential, it might to hypothesize that this multipotent cell compartment is the predominant source of seladin-1. Our aim was to evaluate...

Alopecia areata is an autoimmune disease characterized by non-scarring hair loss with preservation of the follicle. Hair in alopecia can be either focal appearance clearly defined foci alopecia, or diffuse complete any area skin where follicles are present. Data on role food allergy development and nature sensitization spectrum extremely scarce. Objective: to study features pollen (cross-reacti...
