Hyponatremia is the most prevalent electrolyte disorder in hospitalized patients. Vasopressin plays an important role in the pathogenesis of this disorder through its action on the vasopressin type 2 receptor (V(2)R), leading to electrolyte-free water reabsorption. Multiple vasopressin receptor antagonists have recently been developed that differ in their(More)
Diastasis or divarication of the rectus abdominus muscles describes the separation of the recti, usually as a result of the linea alba thinning and stretching. This review examines whether divaricated recti should be repaired and tries to establish if the inherent co-morbidity associated with surgical correction outweighs the benefits derived. EMBASE,(More)
Hyponatremia is reported to be the most common electrolyte abnormality encountered in clinical practice. Diagnosis and principles of management of hyponatremia are everyday issues in patient care. Interest has also been generated by its association with adverse prognosis from studies in specific disease groups. Patients with human immunodeficiency virus(More)
We describe a young woman with longstanding resistant hypertension. Evaluation for renal artery stenosis and primary aldosteronism was unrevealing. In this setting of a suppressed plasma aldosterone concentration (PAC) and a suppressed plasma renin activity (PRA), a differential diagnosis of a deoxycorticosterone (DOC) producing tumor was entertained.(More)
Hypertension affects about 65 million individuals in the United States. In adult patients, primary aldosteronism and renovascular causes are described as most prevalent. Vesicoureteral reflux as a cause of hypertension, while commonly described in pediatric populations, is less prevalent in the adult population especially in the absence of proteinuria. We(More)
