- A 10-Year Retrospective Analysis of Methyl Aminolevulinate Photodynamic Therapy Consultation at the Hospital de BragaPublication . Brito, C; Resende, C; Oliveira, PPhotodynamic therapy (PDT) is a well-established treatment for actinic keratosis (AK), basal cell carcinoma (BCC), and Bowen's disease (BD). The object of this study was to describe the results of a retrospective analysis of patients treated with methyl aminolevulinate PDT (MAL-PDT) with red light, over the past decade at the Hospital de Braga (Braga, Portugal).
- 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.

- Bleomycin-induced flagellate hyperpigmentationPublication . Resende, C; Araújo, C; Gomes, J; Brito, CBleomycin is a chemotherapeutic agent used in the treatment of different tumours. It has several side effects, including flagellate hyperpigmentation, which is a unique and a well-documented side effect of bleomycin therapy. We report a case of a 23-year-old woman with a personal history of ovarian dysgerminoma, who developed flagellate hyperpigmentation on trunk after bleomycin therapy.
- Cannabis arteritis: ever more important to considerPublication . Santos, RP; Resende, C; Vieira, AP; Brito, CCannabis arteritis (CA) is a major and underdiagnosed cause of peripheral arterial disease in young patients. A 34-year-old man, daily smoker of 20 cigarettes and two cannabis cigarettes for 14 years, presented with a necrotic plaque of left hallux for 3 weeks. The Doppler ultrasound and angiography were compatible with severe Buerger's disease. Submitted to a revascularisation procedure and hypocoagulation with rivaroxaban. He had ceased smoking but maintained consumption of cannabis. Owing to the persistence of distal necrosis, amputation of the hallux was performed with good evolution. CA is a subtype of Buerger's disease. It is poorly known but increasingly prevalent and manifests in cannabis users regardless of tobacco use. The drug is considered at least a cofactor of the arteriopathy. The most effective treatment is cessation of consumption. Being cannabis one of the most consumed drugs, its mandatory to ask about its use in all young patients with arteriopathy.
- A Case of IFAP Syndrome with Severe Atopic DermatitisPublication . Araújo, C; Gonçalves-Rocha, M; Resende, C; Vieira, AP; Brito, CIntroduction. The IFAP syndrome is a rare X-linked genetic disorder characterized by the triad of follicular ichthyosis, atrichia, and photophobia. Case Report. A three-month-old Caucasian, male patient was observed with noncicatricial universal alopecia and persistent eczema from birth. He had dystrophic nails, spiky follicular hyperkeratosis, and photophobia which became apparent at the first year of life. Short stature and psychomotor developmental delay were also noticed. Histopathological examination of skin biopsy on left thigh showed epidermis with irregular acanthosis, lamellar orthokeratotic hyperkeratosis, and hair follicles fulfilled by parakeratotic hyperkeratosis. The chromosomal study showed a karyotype 46, XY. Total IgE was 374 IU/mL. One missense mutation c.1360G>C (p.Ala454Pro) in hemizygosity was detected on the MBTPS2 gene thus confirming the diagnosis of IFAP syndrome. Conclusions. We describe a boy with a typical clinical presentation of IFAP syndrome and severe atopic manifestations. A novel missense mutation c.1360G>C (p.Ala454Pro) in MBTPS2 gene was observed. The phenotypic expression of disease is quantitatively related to a reduced function of a key cellular regulatory system affecting cholesterol and endoplasmic reticulum homeostasis. It can cause epithelial disturbance with failure in differentiation of epidermal structures and abnormal skin permeability barrier. However, no correlation phenotype/genotype could be established.

- 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.

- Cutaneous Phaeohyphomycosis Caused by Alternaria alternata Unresponsive to Itraconazole TreatmentPublication . Gomes, J; Vilarinho, C; Duarte, ML; Brito, CCutaneous alternariosis is an opportunistic infection that has been described mainly in patients treated with corticosteroids. We report a case of dermal alternariosis occurring in a woman treated with corticosteroids after a neurosurgery that was unresponsive to itraconazole. Treatment with intravenous voriconazole was initiated, followed by oral protocol, with marked improvement of the lesions.
