Real-Time Dialysis Dose: Ionic Dialysis Versus Classical Urea Kinetic Modeling Indices.

Introduction Worldwide, over 850 million people need renal replacement therapy, and over 80% of them are on hemodialysis. The term "dialysis adequacy" is most often associated with the achievement of minimally acceptable indices - single pool Kt/V (spKt/V) and urea reduction ratio (URR%) and largely does not take into account other clinical indicators in patients. In addition, it should be taken into account that in the conditions of clinical practice, their measurement is carried out according to standards controlled by the regulatory structures and is carried out with a frequency between one and three months, and not during each dialysis procedure.

A Rare Case of a Plunging Ranula in a 42-Year-Old Male Patient: A Case Report.

Plunging ranulas are rare retention pseudocysts of the major salivary glands, most often of the sublingual gland, and usually occur in individuals from the first to the sixth decade of life with female predominance. Given their similar location and physical and imaging characteristics to thyroglossal cysts, distinguishing the two lesions is often a differential diagnostic dilemma even for the experienced physician. This case report presents a 42-year-old man for whom a preliminary diagnosis of a thyroglossal duct cyst was made based on a physical examination.

Online Hemodiafiltration: A New Perspective for Patients With End-Stage Renal Disease.

Introduction Online hemodiafiltration (OL-HDF) is the most effective renal replacement therapy (RRT), which allows the enhanced removal of small and large uremic toxins by combining diffusion and convective transport of solutes. Although the goal of OL-HDF is to provide greater clearance of solutes with a preference for intermediate molecules responsible for many of the complications of chronic kidney disease (CKD), the studies reported to date and their meta-analyses are conflicting in nature and do not show a significant advantage of convective therapies on patient prognosis. Materials and methods At the Clinic of Nephrology and Dialysis, University Hospital "St.
