Value of Neutrophil-Lymphocyte and Platelet-Lymphocyte Ratios in the Evaluation of Acute Rejection and Chronic Allograft Nephropathy in Children With Kidney Transplantation.

Objectives: Neutrophil-to-lymphocyte ratio and platelet (thrombocyte)-to-lymphocyte ratio have become accepted markers of inflammation in recent years and are used to assess disease activity in some diseases. In this study, we investigated the relationship between these values and acute rejection attacks, as well as their role in determining chronic allograft nephropathy, in follow-up of pediatric kidney transplant recipients.

Materials And Methods: Our study included 58 kidney transplant recipients (age 5-18 years) with at least 5-year follow-up at our center.

Protracted febrile myalgia as a challenging manifestation of familial Mediterranean fever: case-based review.

Protracted febrile myalgia syndrome (PFMS) in familial Mediterranean fever (FMF) patients is a vasculitic condition characterized by severe myalgia, fever, abdominal pain, diarrhea, and arthralgia/arthritis episodes lasting 4-6 weeks. Symptoms typically resolve with corticosteroid treatment. However, in recent years, corticosteroid-resistant PFMS patients have been reported.

Isolated acute lupus pneumonitis as the initial presentation of systemic lupus erythematosus in an 8-year-old girl.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease which has broad pleuropulmonary manifestations. One of the rare and mortal complications is acute lupus pneumonitis, which is reported very rarely, especially in childhood. Herein, we report an 8-year-old girl with isolated acute lupus pneumonitis as the initial presentation that required a lung biopsy for diagnosis.

Whole blood viscosity and cerebral blood flow velocities in obese hypertensive or obese normotensive adolescents.

Background: Obesity affects all major organ systems and leads to increased morbidity and mortality. Whole blood viscosity is an important independent regulator of cerebral blood flow. The aim of the present study was to evaluate the effect of whole blood viscosity on cerebral artery blood flow velocities using transcranial Doppler ultrasound in pediatric patients with obesity compared to healthy controls and analyze the effect of whole blood viscosity and blood pressure status to the cerebral artery blood flow velocities.
