Design and Rationale of the National Observational Multicentric Tunisian Registry of Hypertension: Protocol for Evaluating Hypertensive Patient Care in Clinical Practice.

Background: This study was designed to evaluate the care of hypertensive patients in daily clinical practice in public and private centers in all Tunisian regions.

Objective: This study will provide us an overview of hypertension (HTN) management in Tunisia and the degree of adherence of practitioners to international recommendations.

Methods: This is a national observational cross-sectional multicenter study that will include patients older than 18 years with HTN for a duration of 4 weeks, managed in the public sector from primary and secondary care centers as well as patients managed in the private sector.

Absent lunula: An overlooked finding in chronic kidney disease.

We highlight the importance of a thorough nail examination in every clinical encounter, especially in uremic patients. Absent lunula should prompt the clinician to rule out underlying kidney disease even in the absence of signs of uremia.

The tunneled catheter for haemodialysis: about 52 cases.

Background: Vascular access is a basic and essential tool required for performing renal replacement therapy in end stage renal disease.

Aim: To study the indications of tunneled catheter (KTT) in hemodialysis (HD), identify complications related to the use of KTT and contributing factors, assess the survival and performance of the technique.

Introduction: The making of a vascular access is an angular piece for adequate HD and in good conditions.
