ABSTRACT
Gitelman's syndrome (GS) is a distal convoluted tubule (DCT) defect clinically characterized by hypokalemic metabolic alkalosis. Pregnancy in women with GS often results in severe hypomagnesemia and hypokalemia. We report two cases of successful pregnancies, after previous fetal loss, in patients with GS managed with aggressive oral and intravenous electrolyte repletion. These cases illustrate increased potassium and magnesium requirements over the course of the pregnancies and are notable due to the high doses of electrolytes required. They also demonstrate the possibility of successful pregnancy outcomes with frequent laboratory monitoring and aggressive titration of electrolyte replacement either orally or intravenously to maintain appropriate serum levels necessary to provide a suitable environment for fetal development.

Hypertension is a global health problem and without adequate diagnosis and treatment is a risk factor for morbidity and mortality. Proper assessment of blood pressure is key to diagnosis and management of hypertension. Different methods of measurement are available for use and varying techniques are applied to patient care. Understanding the proper methods of blood pressure measurement both in and out of the physician's office is crucial for providing appropriate care to an individual patient. In addition, understanding the techniques used in research, on which current guidelines are based, is critical for proper application to daily practice. In this article, we review the types of blood pressure measurement techniques, discuss the benefits and limitations to each, explore future technological advances in measurement devices, and provide insight into research techniques, which ultimately guide our practice.

Left ventricular assist devices (LVADs) are used increasingly as a bridge to transplantation or as destination therapy in end-stage heart failure patients who do not respond to optimal medical therapy. Many of these patients have end-organ dysfunction, including advanced kidney dysfunction, before and after LVAD implantation. Kidney dysfunction is a marker of adverse outcomes, such as increased morbidity and mortality. This review discusses kidney dysfunction and associated management strategies during the dynamic perioperative time period of LVAD implantation. Furthermore, we suggest potential future research directions to better understand the complex relationship between renal pathophysiology and mechanical circulatory support.
