Case for diagnosis

Apresenta-se um caso de bullosis diabeticorum, doença rara associada ao diabetes mellitus crônico e complicações como a neuropatia ou nefropatia. As bolhas são tensas e grandes, com pouca inflamação circundante e localização acral, regredindo espontaneamente em cerca de três semanas. O exame histopatológico é inespecífico, e o diagnóstico diferencial deve ser feito com a epidermólise bolhosa, os pênfigos, o penfigóide bolhoso, queimaduras e erisipelas bolhosas.The bullosis diabeticorum is a rare disease associated with Diabetes mellitus of long duration. The clinical manifestations are large and distended acral blisters. The differential diagnosis must be made with epidermolysis bullosa, pemphigus, bullous pemphigoid, burns, erysipelas, arthropod bites and others. The histopathology exam is not typical. The dermatologist should suspect of the disease in long-term diabetic patients of with blisters in acral locations without marked inflammation

Mordeduras de animais (selvagens e domésticos) e humanaa

Human and animal bites are common events representing a significant percentage of emergency medical care. In addition to acute complications such as bleeding and major lacerations, severe infections may occur for both common and unusual species of bacteria. The treatment involves two steps: first aid measures and long term care, for the treatment of secondary infections and repair of damaged tissues. This review discusses these aspects, considering that the medical and other members of the health care team should be aware of complications and therapeutic approaches proposed for these type of injuries.As mordeduras humanas e de animais domésticos e selvagens são comuns e representam uma porcentagem importante dos atendimentos médicos de urgência. Além de complicações agudas como sangramento e grandes lacerações, podem ocorrer infecções graves por espécies comuns e incomuns de bactérias. O tratamento envolve duas etapas: as medidas de primeiros socorros e os cuidados tardios para o tratamento das infecções secundárias e reparos de tecidos lesados. Esta atualização discute estes aspectos, levando em consideração que o médico e outros participantes de equipes de saúde devem ter conhecimento destas complicações e das medidas terapêuticas propostas para estes acidentes

Condroma de sela turca associado a hipopituitarismo: relato de um caso

Os condromas intracranianos são raros, sendo mais comumente encontrados na base do crânio e na região esfenoetmoidal. Nesta localização podem ser confundidos com meningiomas, neurinomas e craniofaringiomas. Os autores apresentam a evolução clínica e as características pela imagem de um paciente portador de condroma da sela turca submetido a excisão tumoral.Intracranial chondromas are rare tumors that generally arise from the skull base or at the sphenoid-ethmoidal region. In these sites chondromas may be misdiagnosed as meningiomas, neurinomas or craniopharyngiomas. The authors present the clinical and radiological findings of a patient who underwent surgery for excision of a sella turcica chondroma

Cardiovascular assessment of patients with Ullrich-Turner's Syndrome on Doppler echocardiography and magnetic resonance imaging

OBJECTIVE: To assess the cardiovascular features of Ullrich-Turner's syndrome using echocardiography and magnetic resonance imaging, and to correlate them with the phenotype and karyotype of the patients. The diagnostic concordance between the 2 methods was also assessed. METHODS: Fifteen patients with the syndrome were assessed by echocardiography and magnetic resonance imaging (cardiac chambers, valves, and aorta). Their ages ranged from 10 to 28 (mean of 16.7) years. The karyotype was analyzed in 11 or 25 metaphases of peripheral blood lymphocytes, or both. RESULTS: The most common phenotypic changes were short stature and spontaneous absence of puberal development (100%); 1 patient had a cardiac murmur. The karyotypes detected were as follows: 45,X (n=7), mosaics (n=5), and deletions (n=3). No echocardiographic changes were observed. In regard to magnetic resonance imaging, coarctation and dilation of the aorta were found in 1 patient, and isolated dilation of the aorta was found in 4 patients. CONCLUSION: The frequencies of coarctation and dilation of the aorta detected on magnetic resonance imaging were similar to those reported in the literature (5.5% to 20%, and 6.3% to 29%, respectively). This confirmed the adjuvant role of magnetic resonance imaging to Doppler echocardiography for diagnosing cardiovascular alterations in patients with Ullrich-Turner's syndrome
