Cystic lesions of the liver

LEARNING OBJECTIVES: To present the CT and MRI features of the cystic liver lesions, with emphasis on the differential diagnosis. BACKGROUND: Cystic liver lesions are a frequent finding in abdominal imaging and may represent a broad spectrum of entities, ranging from benign developmental cysts to malignant neoplasms. Radiological features of various cystic liver lesions frequently overlap. Therefore, it is nece...

The Role of Accessory Obturator Arteries in Prostatic Arterial Embolization

In 9 of 491 patients (1.8%) who underwent prostatic arterial embolization (PAE) for benign prostatic hyperplasia from March 2009-November 2013, prostatic arteries arose from the external iliac artery via an accessory obturator artery (AOA). Computed tomography angiography performed before the procedure identified the variant and allowed planning before the procedure. The nine AOAs were catheterized from a contr...

Wildfire selectivity for land cover type: does size matter ?

Previous research has shown that fires burn certain land cover types disproportionally to their abundance. We used quantile regression to study land cover proneness to fire as a function of fire size, under the hypothesis that they are inversely related, for all land cover types. Using five years of fire perimeters, we estimated conditional quantile functions for lower (avoidance) and upper (preference) quantil...

A test for directional-linear independence, with applications to wildfire orien...

Original Paper ; A nonparametric test for assessing the independence between a directional random variable (circular or spherical, as particular cases) and a linear one is proposed in this paper. The statistic is based on the squared distance between nonparametric kernel density estimates and its calibration is done by a permutation approach. The size and power characteristics of various variants of the test a...

Doença Metabólica Rara. Deficiência em Prolidase

Os autores descrevem um caso de doença metabólica rara: deficiência em prolidase, numa lactente com proptose ocular, irritabilidade, vómitos e eritema macular disperso.O diagnóstico foi suspeitado aos 4.5 meses de idade, baseado na excreção aumentada de imidodipeptideos na urina, e confirmado mediante o doseamento da actividade da prolidase em cultura de fibroblastos da pele.
