- Alopécia Areata: Análise Retrospectiva da Consulta de Dermatologia. Pediátrica (2000-2008)Publication . Rocha, J; Ventura, F; Vieira, AP; Pinheiro, AR; Fernandes, F; Brito, CINTRODUCTION: Alopecia areata usually presents as patchy, nonscarring hair loss. It seems to be an immune mediated disease, whereas genetic predisposition, environmental and psychological triggers may be involved in its aetiology. OBJECTIVES: To study the epidemiology, clinical aspects, associations, and treatment of alopecia areata in the paediatric population of Peadiatric Dermatology outpatients over a 9-year period. Some psychologic characteristics were also assessed. METHODS: Descriptive and retrospective study of all newly diagnosed AA cases seen from January 2000 to December 2008 at the Hospital de São Marcos' Paediatric Dermatology Department. Fifteen patients with AA were interviewed for psycologic evaluation. RESULTS: Forty-eight cases (54% male/46% female) were identified. Mean age at presentation was 7.8 years. Family history of AA was reported in 10% of the cases, and in 25% there was a personal and/or family history of atopy. The majority of patients (82%) had mild disease and topical corticotherapy was the first-line treatment for limited AA. Fifty-four percent of these patients had a complete resolution of the lesions with treatment. Systemic treatment (corticosteroids and/or ciclosporin) was used in 71% of patients with extensive disease (more than 50% hair loss). Only one of these patients had a sustained clinical improvement after treatment. Twelve out of 15 respondents (80%) recalled stressful events preceding hair loss. DISCUSSION: Our findings are similar to those reported in other studies. Epidemiologic studies of AA are available in adulthood but there is a paucity of literature on children with AA. A holistic approach is important in the management of childhood AA as the disease can have a severe psychologic impact on an individual's well-being.

- Coma BlistersPublication . Rocha, J; Pereira, T; Ventura, F; Pardal, F; Brito, CComa blisters are lesions that occur in the setting of a variety of neurological diseases. Although most commonly associated with barbiturate overdose, they can be seen in the setting of coma due to other etiologies. Blisters develop 48-72 h after the onset of unconsciousness. We report the case of a 29-year-old man who presented to the emergency department with confusion and progressive loss of consciousness. He had high serum glucose, abnormal hepatic and kidney function tests and a normal toxicological screening. 24 h after admission he was comatose and was started on antibiotics for presumed bacterial meningoencephalitis. Two days after the onset of coma, multiple tense hemorrhagic blisters appeared on the patient's extremities. Skin biopsy revealed an intraepidermal blister with variable degrees of epidermal necrosis. Five days later the patient was fully recovered with no neurological sequelae. No topical treatment was necessary, with complete resolution of the skin lesions two weeks later.

- Indeterminate cell histiocytosis in association with acute myeloid leukemiaPublication . Ventura, F; Pereira, T; Duarte, ML; Marques, H; Pardal, F; Brito, CIndeterminate cell histiocytosis (ICH) is a rare proliferative disorder, in which the predominant cells share morphologic and immunophenotypic features from both Langerhans and non-Langerhans cell histiocytosis. We describe a 62-year-old man presenting a 2-month history of firm nodular lesions on the upper lip. Histopathology, immunohistochemical, and ultrastructural analysis showed typical findings of ICH. The patient was treated with thalidomide and almost complete regression of the lesions was reached within 7 months. Nevertheless, one month after remission, he developed an acute myeloid leukemia of the subtype monocytic leukemia (M5). The patient's condition rapidly worsened and he died due to a respiratory failure four weeks later. We present this case because apart of being rare it joins the effectiveness of thalidomide and the association with an acute monocytic leukemia. A review of the literature is made.
- Leg ulcer as a manifestation of eosinophilic vasculitis in a patient with hepatitis C virus infection, medicated with pegylated interferon/ribavirin.Publication . Resende, C; Pereira, T; Ventura, F; Brito, CCryoglobulinaemic vasculitis is a complication of hepatitis C virus (HCV) infection, responding to treatment with pegylated interferon (peg-IFN)/ribavirin (RIB), but vasculitis may first appear after treatment with peg-IFN/RIB. A 35-year-old man with HCV infection presented to our department with a 2-month history of a 3.3×3 cm ulcer localised on the right shin, with a regular border, on a violaceous base. Histopathological examination revealed a leucocytoclastic vasculitis, rich in eosinophils. The patient had been treated with peg-IFN/RIB 10 months prior and treatment was discontinued after 2 months because of the appearance of arthralgias and neuropathy. Laboratory investigations revealed positive cryoglobulins, elevation of rheumatoid factor and reduction of C4 after treatment with peg-IFN/RIB. Dressings with a hydrocellular foam were placed and after 2 months the ulcer resolved. We presented this case because of the rarity of development of a cryoglobulinaemic vasculitis in a patient with HCV infection, previously treated with peg-IFN/RIB.
