Predictive factors of infection in patients with chronic kidney disease using hemodialysis catheters.

Background: Infection is the most frequent complication of central venous catheters used for hemodialysis.

Objectives: The purpose of this study was to the determine the central venous catheter-related infection rate at a dialysis center in the Brazilian state of Amazonas and to identify risk factors and the microbiological profile of the infections.

Methods: This was an observational study with prospective data collection over a 12-month period by chart analysis and face-to-face interviews with patients undergoing hemodialysis using central venous catheters at a dialysis center.

Renovascular hypertension secondary to Takayasu's arteritis in a child: Case report.

Introduction: Takayasu arteritis (TA) is a chronic inflammatory arteriopathy of unknown etiology that affects the aorta and its branches. Inflammation leads to arterial stenosis, thrombosis, and aneurysm formation. Management strategies for TA include medical therapy and revascularization procedures after inflammation is controlled.

Forgotten guidewire: A case report.

Introduction: The Seldinger technique for implanting central venous catheters is the most used in the world. A metallic guidewire is employed in it, introduced through the lumen of a venipuncture needle, which serves as a path for the introduction of the central venous catheter. Complications directly related to this technique are of several types, such an insertion of a long-winded segment of the guidewire, which can lead to venous perforation, cardiac perforation, arrhythmias or even guidewire retention/embolization.

Urogenital tuberculosis in a patient with end-stage renal disease.

Tuberculosis is one of the most common infections worldwide with particularly high incidence rates in countries with unfavorable socioeconomic conditions and among persons with impaired immune systems. While most patients with this disease will present with pulmonary tuberculosis, immunocompromised individuals also commonly present with extrapulmonary manifestations. We report the case of a 28-year-old male patient with end-stage renal disease who presented with long-standing systemic symptoms and genitourinary manifestations, who was diagnosed with urogenital tuberculosis both by clinical and microbiologic criteria.
