زمینه و هدف: بیماری دست، پا و دهان (hand foot mouth disease [hfmd])، سندرمی مسری است که توسط ویروس های روده ای از خانواده ی پیکورناویریده ایجاد می شود. با توجه به اهمیت و کم بودن مطالعات درباره ی این بیماری و بروز ضایعات ناخنی در آن، مطالعه ی حاضر با هدف تعیین فراوانی انواع ضایعات ناخنی در کودکان مبتلا به بیماری دست، پا و دهان انجام شد. روش اجرا: در این مطالعه ی مقطعی، 84 کودک مبتلا به hfmd مرا...
1 of 2 DESCRIPTION The patient was a 74-year-old gentleman with underlying palmoplantar psoriasis ( fi gure 1 ). He was electively admitted for left below knee amputation for cutaneous squamous cell carcinoma at his left heel with locoregional spread. He was incidentally found to have symmetrical shortening of his fi ngers. On further questioning, we discovered that this had occurred over a per...
Sir. Nail lichen planus (NLP) is characterized by thinning, longitudinal ridging and distal splitting of the nail plate (1.2). Although mild NLP is usually asymptomatic, deformation of the fingernails is cosmetically distressing. Failure to treat NLP results in nail loss or pennanent nail dystrophy in some cases. Therefore the condition should be treated etïectively in its early stage. NLP is u...
Selenium is an essential micronutrient that functions as an antioxidant. Yet, at higher concentrations, selenium is pro-oxidant and toxic. In extreme cases, exposures to excess selenium can lead to death or selenosis, a syndrome characterized by teeth, hair and nail loss, and nervous system alterations. Recent interest in selenium as an anti- tumorigenic agent has reemphasized the need to under...
Case report: We present the case of a 59 years old patient, which showed multiple blisters, erosions, crusts located on the elbows, knees, hands, and feet; some lesions healed and formed hypo or hyperpigmented. scars in the evolution. On the scalp were observed areas of scar alopecia. In the oral cavity there were extensive erosions, painful dysphagia to both solid and liquid food, which in tim...
Selenium is a naturally occurring substance that is toxic at high concentrations but is also a nutritionally essential element. Hydrogen selenide is the most acutely toxic selenium compound. Acute (short-term) exposure to elemental selenium, hydrogen selenide, and selenium dioxide by inhalation results primarily in respiratory effects, such as irritation of the mucous membranes, pulmonary edema...
Grainyhead-like 2, encoded by GRHL2, is a member of a highly conserved family of transcription factors that play essential roles during epithelial development. Haploinsufficiency for GRHL2 has been implicated in autosomal-dominant deafness, but mutations have not yet been associated with any skin pathology. We investigated two unrelated Kuwaiti families in which a total of six individuals have ...
Common eiders (Somateria mollissima) were fed added Se (as L-selenomethionine) in concentrations increasing from 10 to 80 ppm in a pilot study (Study 1) or 20 (low exposure) and up to 60 (high exposure) ppm Se in Study 2. Body weights of Study 1 ducks and high-exposure ducks in Study 2 declined rapidly. Mean concentrations of Se in blood reached 32.4 ppm wet weight in Study 1 and 17.5 ppm wet w...
SUMMARY Over three successive generations four members of a Sicilian family showed early onset, slowly progressive dystrophy of the finger and toe nails, without any other anomalies or skin signs. Histological examination performed in two patients enabled us to discount lichen planus and other underlying diseases. The hereditary and idiopathic nature of the disease is underlined and a classific...
