The authors report their experience with glomerular lesions after renal transplantation, but exclude recurrent glomerulonephritis. Fourteen cases (3 membranous glomerulopathies and eleven allograft glomerulopathies) are discussed in relation to 98 recipients of 105 renal allografts. Two patients with membranous glomerulopathy had HBs antigen in their serum. A poor graft prognosis is observed in 2 of 3 patients. Among eleven recipients who presented with allograft glomerulopathy, two groups are clearly defined with very different graft prognosis. The severity of the vascular lesions was the sole difference between these two groups. The possible physiopathologic mechanisms of allograft glomerulopathy are discussed. It is worth noting that the role of vesico-ureteric reflux is not a prominent feature of this study.

We describe a case of sarcoidosis in a previously healthy 39-year-old man with the development of an acute kidney injury, requiring renal replacement therapy, as the first manifestation of the disease. The course of the disease was complicated by a сatheter-associated bloodstream infection. According to the histological examination of kidney biopsy samples, granulomatous interstitial nephritis was diagnosed.

Optimizing the longevity of vascular access in hemodialysis patients remains a critical aspect of patient care, given the significant role of arteriovenous fistulas (AVFs) and arteriovenous grafts (AVGs) in enabling effective dialysis. Vascular access complications, such as stenosis, thrombosis, and cannulation-related damage, continue to challenge both the functionality and the sustainability of these access points. Recent advancements underscore the importance of a robust follow-up strategy, integrating clinical evaluations with diagnostic tools like color Doppler ultrasound (CDU) and emerging interventional approaches such as drug-coated balloon (DCB) angioplasty.

Bacteria in the complex and nontuberculous mycobacteria may affect a variety of animal species under human care and pose public health risks as zoonotic pathogens. A case of sudden onset of lethargy and increased respiratory effort in a 5-y-old, intact female reindeer () under managed care had progressed to severe dyspnea despite aggressive treatment. The animal was euthanized due to poor prognosis.

Introduction: Castleman disease is a rare lymphoproliferative disorder, subdivided into three types: unicentric Castleman disease, idiopathic multicentric Castleman disease and human herpesvirus-8 (HHV8) associated multicentric Castleman disease. The retroperitoneum comprises only 13 % of the cases.
Case Presentation: We report a case of a 36-year-old female who presented with skin lesions in a dermatology clinic.

Objective: To investigate the predictive value of tumor iodine concentration obtained with dual-energy CT (DECT) for treatment response in patients treated with immune checkpoint inhibitors (ICI).
Materials And Methods: Retrospective single-center study of consecutive metastatic melanoma and renal cell carcinoma (RCC) patients undergoing first-line ICI treatment. The iodine concentration measurement time points include prior to initiation of therapy (baseline [BL]), after initiation (follow-up [FU1]), and either time point nearest to 12 months or at time of progression (final follow-up [FFU]).
