Clinical presentation and diagnostic evaluation of pheochromocytoma: case series and literature review.

Background: Pheochromocytoma is a rare tumor frequently overlooked mainly due to the wide range of its clinical presentation, which may vary from entirely untypical signs and symptoms to life-threatening complications.

Methods: The present study aims to present a case series recently treated in our center, with emphasis placed on patients' specific characteristics, clinical presentation and diagnostic evaluation. Relevant literature and current guidelines are being briefly reviewed to summarize screening for pheochromocytoma and appropriate diagnostic procedures.

Haemodialysis and peritoneal dialysis patients have severely impaired post-occlusive skin forearm vasodilatory response assessed with laser speckle contrast imaging.

Background: Endothelial dysfunction is associated with cardiovascular events and mortality in various disease states, including end-stage renal disease (ESRD). Novel technological approaches have emerged for real-time assessment of endothelial reactivity. This study examined skin microcirculation using laser speckle contrast imaging (LSCI) before and after arterial occlusion in ESRD patients undergoing haemodialysis (HD) or peritoneal dialysis (PD).

Ambulatory blood pressure profile and blood pressure variability in peritoneal dialysis compared with hemodialysis and chronic kidney disease patients.

Hypertension in end-stage renal disease patients is highly prevalent and poorly controlled. Data on the ambulatory blood pressure (BP) profile and BP variability (BPV) in peritoneal dialysis (PD) patients are absent. This study examined the BP profile and BPV of patients undergoing PD in comparison with hemodialysis (HD) and predialysis chronic kidney disease CKD patients.
