Doença de Behçet - Infliximab no Tratamento das Manifestações Mucocutâneas

A Doença de Behçet (DB) é uma doença inflamatória multisistémica, crónica e recidivante, cujo diagnóstico é essencialmente clínico. Em estudos recentes, os antagonistas do factor de necrose tumoral a têm mostrado bons resultados no tratamento das manifestações mucocutâneas da DB. Os autores descrevem três casos de DB com envolvimento mucocutâneo grave tratados com infliximab. Caso Clínico 1: Doente do sexo feminino de 16 anos de idade, com aftose bipolar grave com 8 anos de evolução. Verificou-se uma rápida resposta clínica à terapêutica biológica, com remissão parcial e total das úlceras à 2ª e 6ª semana de tratamento, respectivamente Caso Clínico 2: Doente do sexo feminino de 56 anos de idade com paniculite nodular crónica dos membros inferiores, artralgias e ulcerações orogenitais recorrentes. Após 6 semanas de terapêutica com infliximab, verificou-se uma remissão clínica completa. Caso Clínico 3: Doente do sexo feminino de 50 anos de idade, com ulcerações orofaríngeas recorrentes com 15 anos de evolução. Observou-se uma boa resposta clínica à terapêutica biológica, que foi interrompida à 22ª semana por abcessos dentários recorrentes. Na nossa experiência, o infliximab é uma alternativa terapêutica eficaz a considerar na presença de manifestações mucocutâneas resistentes aos tratamentos convencionais.

Torpedo Maculopathy with an Anisometropic Amblyopia in a 5-Year-Old Caucasian Girl: Case Report

The aim of this study is to report a clinical case of asymptomatic female Caucasian children with torpedo maculopathy. A 5-year-old girl was referred to our clinic for routine evaluation. The ophthalmic examination revealed best-corrected visual acuity of 20/20 in both eyes, without any changes in the biomicroscopy. Fundus examination showed normal findings in one eye, whereas in the contralateral eye it disclosed, in the temporal sector of the macular region, a whitish, atrophic, oval chorioretinal lesion with clearly defined margins. Posterior evaluations documented the stability of the lesion. Torpedo maculopathy diagnosis is based on its characteristic shape and peculiar location. The differential diagnosis has to be established versus choroidal lesions (melanoma and nevus), congenital or iatrogenic hyperplasia of the retinal pigment epithelium (RPE) and particularly versus the congenital pigmented lesions associated with Gardner's syndrome.

Propylthiouracil Induced Pulmonary-Renal Syndrome: a Case Report.

Propylthiouracil (PTU) is known to induce antineutrophil cytoplasmatic antibody (ANCA) seropositivity; however, small vessel vasculitis (SVV) with pulmonary and renal involvement is rare. We present the case of an 81-year-old woman on PTU treatment due to toxic nodular goitre who developed alveolar hemorrhage and rapidly progressive glomerulonephritis. The authors highlight the importance of early recognising drug-induced pulmonary-renal syndrome (PRS) in order to avoid unnecessary tests, a delay in the diagnosis and evolution to end-stage kidney disease or life-threatening conditions.

Long-Term Recurrence of Nonmelanoma Skin Cancer after Topical Methylaminolevulinate Photodynamic Therapy in a Dermato-Oncology Department

BACKGROUND: Most available studies on the efficacy of topical photodynamic therapy focus on short-to medium-term results. Long-term data are scarce. OBJECTIVE: To evaluate the long-term efficacy of photodynamic therapy with topical methylaminolevulinate to treat Bowen's disease and basal cell carcinoma in the clinical practice setting of a dermato-oncology department. METHODS: The study included patients diagnosed with Bowen's disease or basal cell carcinoma, and who received photodynamic therapy from 2004 to 2008. Treatment protocol and clinical follow-up were standardized. The primary endpoint was clinically observed recurrence in a previous photodynamic therapy-treated area. Descriptive and survival analyses were performed. RESULTS: A total of 31 Bowen's disease lesions and 44 superficial basal cell carcinoma were treated, with a median follow-up of 43.5 months. Recurrence was observed in 14 Bowen's disease lesions (53.8%) and in 11 superficial basal cell carcinoma (33.3%). Significantly higher estimates for recurrence rates were found in patients with Bowen's disease (p=0.0036) or those aged under 58 years (p=0.039). The risk of recurrence was higher in patients with Bowen's disease than in those with superficial basal cell carcinoma and younger patients. CONCLUSIONS: Recurrence should be considered when choosing to treat non-melanoma skin cancer with photodynamic therapy. Younger age and Bowen's disease were independent predictors for long-term recurrence, suggesting the need to establish an extended period of follow-up for this subset of patients.
