Retrospective analysis of clinical and pathomorphological features of lupus nephritis in children.

Purpose: The aim of the study was to evaluate the clinical course and pathomorphological correlations in Polish children with the diagnosis of lupus nephritis (LN).

Methods: We retrospectively analyzed the medical records of 39 children hospitalized due to LN in 7 pediatric nephrology units in Poland between 2010 and 2019. Demographic data, clinical symptoms at the onset of LN and laboratory parameters were reviewed.

The relationship between jumping to conclusions and neuropsychological functioning in schizophrenia.

Jumping to conclusions (JTC) is defined as a tendency to make decisions based on insufficient information. JTC has been reported in patients with psychosis, but the mechanisms of this cognitive bias remain unknown. The main aim of our study was to investigate the relationship between JTC and neuropsychological functioning in schizophrenia.

Endothelin-1 (ET-1), N-terminal fragment of pro-atrial natriuretic peptide (NTpro-ANP), and tumour necrosis factor alpha (TNF-α) in children with primary hypertension and hypertension of renal origin.

Introduction: Hypertension is regarded as a condition of mild inflammation and endothelial imbalance. The aim of the study was to evaluate serum concentrations of biomarkers of inflammation and endothelial function: tumour necrosis factor alpha (TNF-α), endothelin-1 (ET-1), and N-terminal fragment of pro-atrial natriuretic peptide (NTpro-ANP) in hypertensive and normotensive children.

Material And Methods: We studied 63 children aged 13.

Non-dipping status and selected adipokines concentration in children with primary arterial hypertension.

Unlabelled: High blood pressure (BP) in children and adolescents is associated with increased risk of persistent hypertension (HT) in adulthood and, consequently, cardiovascular disease and target organ damage.

Aim: The values of selected anthropometric parameters and laboratory test results including leptin and apelin concentration were evaluated with regard to averaged values of office BP measurements and 24-hour ABPM.

Material And Methods: The study included 55 children: 23-with primary HT and coexisting overweight or obese (HT-OB), 16-with primary HT and normal weight (HT-NW), and 16 healthy children (C).

The increasing incidence of initial steroid resistance in childhood nephrotic syndrome.

Background: Recently, a number of reports have highlighted changes in the histopathology and response to corticosteroid treatment in childhood nephrotic syndrome; however, these involved ethnically mixed populations. For comparison, the purpose of our research was to search for changes in the characteristics of nephrotic syndrome in a homogeneous population of Caucasian children over two consecutive decades.

Methods: Chart analysis was performed to identify children with new-onset nephrotic syndrome.

Percutaneous endoscopic gastrostomy as a method of nutrition support in children with chronic kidney disease.

Chronic kidney disease (CKD) exerts a significant impact on children's growth and development. In infants and children with CKD, feeding-related problems are not infrequent, leading to protein-energy malnutrition and resulting in retarded physical development. Because spontaneous energy intake is usually inadequate in children with CKD, special dietary counseling with supportive procedures are often required.

Bone metabolism and the muscle-bone relationship in children, adolescents and young adults with phenylketonuria.

The aim of the study was to assess body composition in subjects with phenylketonuria (PKU). Forty-five patients aged 13.8 ± 5.

Utility of the dobutamine stress echocardiography in the evaluation of the effects of a surgical repair of aortic coarctation in children.

Background: Exercise-induced hypertension following repair of the coarctation of the aorta (CoA) is a well known phenomenon. The most important functional parameters in the assessment of the effects of a surgical repair of CoA are the maximal pressure gradient in the descending aorta (GRAD) and systolic blood pressure (SBP). Results of treadmill exercise test using the Bruce protocol (treadmill test) and dobutamine stress echocardiography (DSE) were compared to determine utility of the DSE in the evaluation of the effects of surgical treatment of CoA in children.

[Diagnostic value and safety of percutaneous kidney biopsy in experience of one clinical center].

Unlabelled: Percutaneous kidney biopsy is a widely applied diagnostic procedure providing with kidney tissue for microscopy.

Aim Of The Study: The assessment of diagnostic value of kidney tissue specimens gained by percutaneous biopsy and the assessment of that method's safety.

Material: 119 percutaneous kidney biopsies performed on patients of Pediatric Clinic in Zabrze from 1998 through 2007 were analysed.
