Clinical features of rhabdomyolysis after open and laparoscopic Roux-en-Y gastric bypass.

Background: Rhabdomyolysis (RML) is caused by muscle injury, this may cause kidneys overload and lead to acute renal failure (ARF). The risk factors for RML in bariatric surgery (BS) are operative time (OT) >4 h and high BMI. The frequency of RML in BS varies from 12.

Occurrence rate and clinical predictors of hypertensive pseudocrisis in emergency room care.

Objectives: To describe the prevalence of hypertensive pseudocrisis in patients treated in emergency rooms with substantially elevated blood pressure levels. To compare this prevalence in private and public hospitals. To describe the frequency of wrong treatment for this condition.

Incidence and predictors of development of acute renal failure related to treatment of congestive heart failure with ACE inhibitors.

Background/aims: Recent studies have shown high rates of morbimortality associated with hyperkalemia in congestive heart failure (CHF) patients treated with angiotensin-converting enzyme inhibitors (ACEI) plus spironolactone and the best predictor of this electrolytic disorder was a decrease in renal function. We aim to identify the incidence and predictors of acute renal failure (ARF) related to treatment with ACEI associated or not with spironolactone.

Methods: We conducted a cohort study and followed 114 consecutive cases of CHF patients treated with ACEI at admission to a University Hospital.

Hyperkalaemia in congestive heart failure patients using ACE inhibitors and spironolactone.

Background: Recent studies have shown a fall in global mortality with minimal side effects in severe congestive heart failure (CHF) patients receiving angiotensin-converting enzyme inhibitors (ACEI) plus spironolactone (SLN). However, the risk of hyperkalaemia due to ACEI may be increased by the concomitant use of SLN.

Methods: We conducted a retrospective cohort study by examining consecutive cases of severe decompensated CHF admitted to a university hospital in Brazil from March 1999 to March 2000, which had used ACEI with or without SLN.
