Adolescence-onset atypical hemolytic uremic syndrome: is it different from infant-onset?

Background: Atypical hemolytic uremic syndrome (aHUS) is a rare, mostly complement-mediated thrombotic microangiopathy. The majority of patients are infants. In contrast to infantile-onset aHUS, the clinical and genetic characteristics of adolescence-onset aHUS have not been sufficiently addressed to date.

Acute kidney injury in pediatric burn patients.

Background: Acute kidney injury (AKI) is a common and important complication of burn injury. Although there are numerous adult studies, data regarding AKI in pediatric burn patients are scarce. Here, we aimed to evaluate the frequency, clinical features, and prognosis of AKI among pediatric burn injury patients.

A Nine-year-old Boy with Renovascular Hypertension: Knowing Where to Look.

Renal artery entrapment (RAE) by hypertrophic diaphragmatic crura is an extremely rare cause of renovascular hypertension (RVH). Here, we report the case of a 9-year-old boy diagnosed with RVH caused by right RAE by a hypertrophic diaphragmatic crus and successfully managed with close medical monitoring. Diagnosis of this entity is easily overlooked if the optimal views are not obtained during imaging, which depends on a high index of suspicion.

COVID-19 in pediatric nephrology centers in Turkey.

Background/aim: There is limited data on COVID-19 disease in children with kidney disease. We aimed to investigate the characteristics and prognosis of COVID-19 in pediatric nephrology patients in Turkey.

Materials And Methods: This was a national, multicenter, retrospective cohort study based on an online survey evaluating the data between 11 March 2020 and 11 March 2021 as an initial step of a detailed pediatric nephrology COVID-19 registry.

Spontaneous remission of nephrotic syndrome associated with COVID-19 infection in an 8-year-old boy.

Background: It is already known that viral infections, exclusively upper respiratory tract infections may trigger relapses of nephrotic syndrome. Recently, COVID-19 disease has also been reported to be related with relapse of nephrotic syndrome in a few pediatric cases Case. Here we present an 8-year-old boy who had relapse of nephrotic syndrome due to COVID-19 infection.

Premature ovarian failure in juvenile systemic lupus erythematosus patient: A rare presentation.

A 16-year-old girl was admitted to the hospital for the absence of a menstrual bleeding over 10 mounts. She has had regular menstrual periods since she was 13 years old and no history of systemic disease. Laboratory tests showed low estrogen (<11.

Can microalbuminuria be an ındicator of renal ınvolvement in pediatric Covid 19 patients?

Background: Proteinuria (both tubular and glomerular in origin) and its implications are well-known features of adult patients with COVID19. However currently studies addressing proteinuria and its role in the outcome of kidney and patients of pediatric COVID 19 is scarce. We aimed to evaluate the presence of microalbuminuria in order to detect early renal involvement in pediatric COVID 19 patients.

Could plasma based therapies still be considered in selected cases with atypical hemolytic uremic syndrome?

Background: Atypical hemolytic uremic syndrome (aHUS) occurs due to defective regulation of the alternative complement pathway (ACP) on vascular endothelial cells. Plasma based therapy (PT) was the mainstay of the treatment for aHUS for many years until the introduction of therapies targeting blockage of the complement system. The aim of this study was to evaluate patients with aHUS who had been treated with plasma based therapies alone.

Effect of enuresis on perceived parental acceptance-rejection in children.

Objective: Enuresis is a major problem affecting both the child and his family. This study aimed to investigate the effect of enuresis on mother acceptance-rejection perceived by children.

Material And Methods: Fourty-six children and their mothers with the diagnosis of primary enuresis were included in the study.

Parvovirus B19 infection mimicking systemic lupus erythematosus, successfully treated with intravenous immune globulin.

Introduction: Parvovirus B19 infection generally presents as a transient viral illness in children but rarely shows systemic lupus erythematosus-like symptoms.

Case Report: Here we present a 7-year-old girl with parvovirus B19 infection who had prolonged fever, rash, pancytopenia and hypocomplementemia making it difficult do differentiate from the first episode of systemic lupus erythematosus. Because she had severe progressive pancytopenia she was administered intravenous immune globulin treatment and her clinical course was dramatically improved.

Ambulatory blood pressure abnormalities in children with migraine.

Background: Although there are data showing that the frequency of hypertension increases in adults with migraine, there has been no study on this subject in children. In this study, we aimed to evaluate the presence of hypertension in children with migraine by performing ambulatory blood pressure monitoring (ABPM).

Methods: Thirty-seven children diagnosed with migraine and 30 healthy controls were evaluated between January 2015 and March 2016.

Renal Biopsy Prognostic Findings in Children With Atypical Hemolytic Uremic Syndrome.

Background: The aim of this study was to investigate the histopathological findings in kidney biopsies in children with atypical hemolytic uremic syndrome (aHUS) and to determine whether specific pathological findings in aHUS have a prognostic value.

Methods: Renal biopsy specimens of 29 patients who were recorded in the national Turkish aHUS registry database were available for review. Histopathological findings were compared with the clinical and laboratory features at the presentation and the final outcome.
