Clínica e Evolução do Rim Multiquístico: Que Dilemas?

O rim multiquístico (RM) consiste numa forma de displasia renal extrema em que o parênquima renal é substituído por múltiplos quistos, duetos e glomérulos primitivos sem qualquer função.Com o objectivo de avaliar se ocorreram modificações nos últimos anos na forma de diagnosticar, investigar e tratar as crianças com RM, efectuámos a análise retrospectiva dos 38 casos de RM seguidos no Hospital Pediátrico de Coi...

Coordinated Multi-Point MIMO Processing for 4G

The concept of cooperative Multiple-Input-Multiple-Output (MIMO), also referred to as network MIMO, or as Coordinated Multi-Point Transmission (CoMP), was standardized in 3GPP Release 11. The goal of CoMP is to improve the coverage of high data rates and cell-edge throughput, and also to increase system throughput. In this paper we analyze only the latter scenario, using system level simulations in accordance w...

Diversity in UV sensitivity and recovery potential among bacterioneuston and ba...

Aims: To assess the variability in UV-B (280–320 nm) sensitivity of selected bacterial isolates from the surface microlayer and underlying water of the Ria de Aveiro (Portugal) estuary and their ability to recover from previous UVinduced stress. Methods and Results: Bacterial suspensions were exposed to UV-B radiation (3Æ3 W m)2). Effects on culturability and activity were assessed from colony counts and 3H-leu...

A rare cause of pericardial disease

Among cardiovascular diseases, pericardial disease has specific characteristics. Its etiology, diagnosis and medical management are not as well understood as in coronary and valvular heart disease. In most cases, its cause is benign, although the proportion decreases with more severe clinical presentation. The authors present the case of a 35-year-old man with no relevant past medical history, who went to the e...

Mesalamine-induced myocarditis following diagnosis of Crohn's disease: a case r...

Mesalamine is a common treatment for Crohn's disease, and can be rarely associated with myocarditis through a mechanism of drug hypersensitivity. We present the case of a 19-year-old male who developed chest pain two weeks after beginning mesalamine therapy. The electrocardiogram showed slight ST-segment elevation with upward concavity in the inferolateral leads; blood tests demonstrated elevated troponin I and...

Role of central obesity in risk stratification after an acute coronary event: D...

BACKGROUND: Accurate risk stratification is an important step in the initial management of acute coronary syndrome (ACS), and current guidelines recommend the use of risk scores, such as the Global Registry of Acute Coronary Events risk score (GRACE RS). Recent studies have suggested that abdominal obesity is associated with cardiovascular events in patients with ACS. However, little is known about the addition...
