Pneumonia caused by Pneumocystis jirovecii is an uncommon infection in kidney transplant patients that can have an acute and rapid progression to respiratory failure and death. The period of greatest risk occurs in the first six months after the transplant, and it relates to the high doses of immunosuppression drugs required by patients. However, it may occur late, associated with the suspension of prophylaxis with trimethoprim-sulfamethoxazole.We present two cases of renal transplant patients who had severe hypoxemic respiratory failure due to P...

BACKGROUND: Hemodialysis is a common treatment for end-stage renal disease, and maintenance of access patency remains a key issue. Angioplasty is recommended as the first choice for access stenosis, but it poses a risk of a high rate of restenosis. Stent graft placement can generate a high patency rate of dialysis access. This study aimed to compare the primary patency of the treatment area and access circuit between stent grafts and angioplasty in dialysis access failure. MATERIALS AND METHODS: Three electronic databases, namely, PubMed, Cochrane Library of Systematic Reviews, and EMBASE, were searched from the database inception to September 2017 without language restriction...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether the anterolateral or the inferior wall served as a better location for the 2nd arterial graft in a 3-system coronary artery bypass grafting procedure. In total, more than 1800 papers were found, of which 6 represented the best evidence to answer the clinical question. All papers demonstrated equivalent early postoperative mortality and morbidity. The 3 largest studies comparing bilateral internal thoracic arteries showed no difference in perioperative mortality and morbidity regardless of whether the 2nd internal thoracic artery was used to graft the left or right system...

Vesicoureteral reflux after renal transplantation is associated with increase risk of urinary tract infections, renal scarring, and graft failure. We describe a case of a 46-year-old woman with 2 transplant kidneys, one functioning and another nonfunctioning, presenting with pelvic pain after a bilateral periureteral bulking procedure. Diuretic renography was performed to exclude iatrogenic ureteral obstruction. This showed a normally functioning transplant kidney without obstruction and subsequent vesicoureteral reflux into the collecting system of the nonfunctioning transplant kidney...

INTRODUCTION: Hypoparathyroidism still represents an important concern in thyroid surgery. Careful dissection with identification and preservation of parathyroid glands in situ remains the best way to maintain gland vitality and avoid post-operative failure. Nevertheless, parathyroid glands are still inadvertently removed in up to 11% of cases. Parathyroid autotransplantation may represent the only way to restore parathyroid gland functionality in case of inadvertent removal or devascularization during thyroid surgery...

Graft size in hamstring autograft anterior cruciate ligament (ACL) surgery is an important factor directly related to failure. Most of the evidence in the field suggests that the size of the graft in hamstring autograft ACL reconstruction matters when the surgeon is trying to avoid failures.The exact graft diameter needed to avoid failures is not absolutely clear and could depend on other factors, but newer studies suggest than even increases of 0.5 mm up to a graft size of 10 mm are beneficial for the patient...

The purpose of this study was to examine outcomes after cryopreserved tri-cortical iliac crest allograft reconstruction for glenoid bone loss in patients with shoulder instability. 10 patients completed the required assessments at a mean follow up of 4.5 years. At final follow up, mean ASES was 92 ± 12, mean WOSI was 315 ± 319, with good range of motion. None of the final radiographs demonstrated graft resorption or failure of hardware. The data demonstrated that patients who were treated with glenoid bone grafting with cryopreserved tri-cortical iliac crest allograft can expect good range of motion and functional capacity...

The fistula first initiative has rekindled interest in transposition of basilic vein (TBV) in preference to arteriovenous grafts (AVG). TBV is considered to have advantages over AVG. The aim of this study was to analyze the outcome of TBVs in our center comparing them to a historically matched group of patients who had AVG. Thirty-two patients who underwent TBV as a vascular access procedure in Derriford Hospital between January 2010 and October 2014 were included in the study. The historical control group comprised 31 patients who had AVG inserted in the upper arm between January 1999 and December 2010...

OBJECTIVES: Chronic graft versus host disease (GVHD) is one of the major obstacles to achieve success in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Extracorporeal photochemotherapy (ECP) has been demonstrated to be an effective modality for the treatment of GVHD in previous studies but they vary in terms of initiation and duration. Our aim is to demonstrate the characteristics of our patients who received ECP for chronic GVHD to clarify the best treatment scheme. MATERIAL AND METHODS: In this study, we retrospectively evaluated 34 patients with steroid refractory chronic GVHD (n=34) who were treated with ECP between 2001 and 2015...
