[Collapsing Glomerulopathy Secondary to Anabolic Steroids for Bodybuilding: A Case Series].

The abuse of anabolic androgenic steroids (AAS) for competitive (and non-competitive) purposes for bodybuilding practice is increasingly common. The consequences of these substances on the various organs are only partially known. Cases of FSGS following the use of AAS have been reported in the literature, even with evolution to ESKD.

Urate-Lowering Agents in Asymptomatic Hyperuricemia: Role of Urine Sediment Analysis and Musculoskeletal Ultrasound.

Current urate-lowering therapy (ULT) includes three direct acting drugs (allopurinol, febuxostat, Rasburicase) and at least four 'indirect' drugs with other important targets (canagliflozin, losartan, fenofibrate and sevelamer). Moreover, the alcalinization of urines using bicarbonate can be used to dissolve urate crystals and the clinician may discontinue several drugs are known to increase serum levels of uric acid, such as diuretics, aspirin, cyclosporine, theophylline, mycophenolate and ACE inhibitors. While there is a consensus to start ULT in cases of symptomatic hyperuricemia (gout, urate-nephrolithiasis), the very frequent conditions of asymptomatic hyperuricemia remains a major conundrum.

Ramipril in post-renal transplant erythrocytosis.

Background: Posttransplant erythrocytosis (PTE; i.e., hematocrit [Ht] >=51%) may be responsible for cardiovascular events.

[Role of directional power-Doppler in the identification of renovascular malformations].

Objective: The directional power-Doppler (dPD) is a useful tool in evaluating the renal vascularization for its high sensibility and availability. Renal vascular malformations like the arteriovenous fistulas (avF) are rare and their real incidence is unknown. We evaluated the diagnostic role of dpD in renal avF.
