Intentional vomiting as a rare cause of hypercalcemia and consequent acute renal failure: a case report.

Two most common causes of elevated serum calcium levels, which together account for nearly 90% of all cases, are primary hyperparathyroidism and malignancy. Thus, it is necessary to consider other disorders in the diagnostic evaluation of patients with hypercalcemia. We report the case of a 40-year-old female patient with an intellectual disability who was admitted to the Emergency Department with severe symptomatic hypercalcemia and acute renal failure, caused by recurrent intentional vomiting.

On-admission serum uric acid predicts outcomes after acute myocardial infarction: systematic review and meta-analysis of prognostic studies.

Aim: To evaluate the prognostic value of serum uric acid (SUA) in acute myocardial infarction (AMI) patients.

Methods: Systematic review and random-effects meta-analysis of prognostic studies assessing AMI outcomes (death, major adverse cardiac events, MACE) in relation to on-admission SUA.

Results: Nine studies (7655 patients) were identified, 6 in the ST-segment elevation AMI patients treated with invasive revascularization and three in mixed AMI type cohorts with variable reperfusion strategies.

Aortic dissection presenting as crossed hemiparesis.

Introduction: Aortic dissection is frequently associated with ischemic stroke; however, a high clinical suspicion is necessary when the presentation is atypical.

Case Report: We present the atypical clinical picture of De Bakey type I (Stanford A) aortic dissection which presented as crossed hemiparesis in a 52-year-old previously healthy woman.

Conclusion: This case emphasizes the need for assessing pulsations of peripheral arteries on both arms and both legs in the context of acute stroke as this could lead to the diagnosis of acute aortic dissection.

Higher serum uric acid on admission is associated with higher short-term mortality and poorer long-term survival after myocardial infarction: retrospective prognostic study.

Aim: To assess serum uric acid (SUA) levels determined on admission as a potential predictor of short-term mortality and long-term survival in acute myocardial infarction (AMI) patients.

Method: Data for this retrospective prognostic study were drawn from the patient database of the Varazdin County General Hospital in Varazdin, Croatia. We included consecutive patients with verified AMI admitted within 48 hours since the symptom onset during the period between 1 January 1996 and 31 December 2001.

Prostate specific antigen density can help avoid unnecessary prostate biopsies at prostate specific antigen range of 4-10 ng/ml.

Elevated level of prostatic specific antigen (PSA) is an established parameter to help determine the need to perform prostate biopsy. The aim of the present study was to determine whether PSA density (PSAD) could better predict pathologic finding of 12-core prostate biopsy in men with PSA 4-10 ng/mL than PSA alone. Transrectal ultrasound guided biopsy was performed in 125 men with PSA within this range.
