RETRACTED: Ventricular Ectopic Beats: An Overview of Management Considerations.
Ventricular ectopic beats are commonly seen in daily clinical practice. Majority of them being asymptomatic, some can cause symptoms. In a normal heart, their occurrence is of no clinical significance. ⋯ Recent reports on the use of catheter ablation in cases where focal ventricular ectopics are found to trigger ventricular fibrillation. Clinical evaluation and investigations are important in assessing patients with ventricular ectopic beats so that appropriate treatment can be targeted when necessary. This article discusses the current knowledge and practice in this commonly encountered clinical problem.

Acute kidney injury (AKI) is a rare complication of carcinoid syndrome. A 61-year-old man developed carcinoid syndrome 51 months after pneumonectomy for bronchial carcinoid, and 8 episodes of AKI 101 to 118 months after pneumonectomy. Serum chromogranin A and urine 5-hydroxyindoleacetic acid levels were elevated for more than 1 year before AKI occurred. ⋯ Hyponatremia persisted but was more severe during AKI. Elevated plasma levels of vasoactive substances other than 5-hydroxytryptamine, perhaps dopamine or other catecholamines, could explain recurrent AKI. The natriuretic effect of elevated plasma dopamine levels could explain chronic hyponatremia.

Radiological evidence of presence of air or gas within the stomach wall is termed "gastric pneumatosis" and is considered an ominous sign. However, the etiological associations range from benign self-limiting causes to life-threatening emergencies. The authors report the case of gastric pneumatosis in a 34-year-old man who presented to the emergency department with severe abdominal pain after multiple episodes of vomiting. The authors also review the clinical associations of this uncommon condition and discuss risk stratification and management strategies.

Gender divergence on the impact of multiple cardiovascular risk factors on the femoral artery intima-media thickness (IMT) has not been studied in a biracial (black-white) community-based asymptomatic young adults. ⋯ Although men versus women had thicker IMT, the observed increasing trend of femoral IMT with increasing number of risk factors in asymptomatic young women suggests that women may be relatively more susceptible to the burden of multiple risk factors.

The value of measuring procalcitonin (PCT) in patients with community-acquired pneumonia (CAP) is unclear. The aim of this study was to determine the value of PCT as a marker for microbial etiology and a predictor of outcome in CAP patients. ⋯ High PCT levels indicate that pneumococcal pneumonia and PCT levels depend on the severity of pneumonia. PCT measurements may provide important diagnostic and prognostic information for patients with CAP.
