Identifying Roadkill Hotspots for Mammals in the Brazilian Atlantic Forest using a Functional Group Approach.

A critical step to design wildlife mitigating measures is the identification of roadkill hotspots. However, the effectiveness of mitigations based on roadkill hotspots depends on whether spatial aggregations are recurrent over time, spatially restricted, and most importantly, shared by species with diverse ecological and functional characteristics. We used a functional group approach to map roadkill hotspots for mammalian species along the BR-101/North RJ, a major road crossing important remnants of the Brazilian Atlantic Forest.

[Large adrenal pseudocyst mimicking cystic pheochromocytoma: excision minimising laparoscopic access].

Introduction: Adrenal cysts and pseudocysts are rare and usually benign and asymptomatic; they are discovered either accidentally or during examination for non-specific abdominal discomfort. Less frequently, they may cause gastrointestinal symptoms or abdominal or lumbar pain, particularly when they are quite large. Histologically, they are classified as epithelial, endothelial, parasitic and pseudocysts (with a fibrous wall but no epithelium).

[Chylous ascites following radical nephrectomy. Conservative management whithout paracentesis].

Introduction: Chylous ascites is a rare complication after a number of abdominal and retroperitoneal surgeries. Althought conservative treatment may be curative, a reoperation to sell out the open megalymphatics in the operative field may be needed.

Patient And Method: A 60 year-old woman was treated with a laparoscopic radical nephrectomy for a 9.

Muscle invasive bladder tumor 18 months after laparoscopic radical nephroureterectomy.

Objective: The management of the distal ureter and bladder cuff is an important issue related to laparoscopic nephroureterectomy, because of the fear that local and bladder recurrences could be induced by an inadequate manipulation of the specimen. We present a case of muscle invasive bladder tumor that appeared 18 months after laparoscopic radical nephroureterectomy.

Methods/results: A 42 year-old woman with multifocal grade 3 pT3, right kidney urothelial carcinoma, treated by laparoscopic radical nephroureterectomy with early clipping of the distal ureter, transurethral detachment of the intramural ureter, and no bladder closure, presented with an invasive bladder recurrence after 18 months of follow-up.

Mucinous urothelial-type adenocarcinoma of the prostate.

A case of mucinous urothelial-type adenocarcinoma of the prostate in a 68-year-old man is reported. This is a rare neoplasm which probably originates from the proximal prostatic ducts or the prostatic urethra. This tumor does not express prostate-specific antigen, in contrast to the more common mucinous adenocarcinoma of the prostate, and may be misdiagnosed as a secondary, mainly colorectal, tumor.
