Variations of Redox Balance in Different Stages of Childhood Immune Thrombocytopenic Purpura.

Background:  Few previous studies indicated the role of oxidative stress in the pathogenesis of childhood idiopathic thrombocytopenic purpura (ITP), but there are little data regarding changes in redox balance in different forms of the disease, and changes after therapeutic procedures. We aimed to investigate the values of pro-oxidants and antioxidative capacity in various forms of ITP before and after the applying therapy.

Materials And Methods:  The research included 102 children, classified into the following groups: (1) newly diagnosed ITP (ndITP), (2) persistent ITP, (3) chronic ITP (chITP), and (4) control groups: (A) healthy control and (B) previously experienced ITP-healthy children who had been suffering from ITP earlier.

Factors Associated with the Antibiotic Treatment of Children Hospitalized for COVID-19 during the Lockdown in Serbia.

Unselective use of antibiotics to treat children with COVID-19 is one of the major issues during the pandemic in Serbia. Thus far, there has been no evidence about the predictors of multiple antibiotic use in the treatment of children with COVID-19. The purpose of this study was to assess the prevalence of antibiotic use, as well as to examine demographic and clinical factors associated with a greater number of antibiotics and with a longer antibiotic treatment administered to hospitalized children with COVID-19 during the lockdown in Serbia.

Factors for severe outcomes following SARS-CoV-2 infection in people with cystic fibrosis in Europe.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in people with cystic fibrosis (pwCF) can lead to severe outcomes.

Methods: In this observational study, the European Cystic Fibrosis Society Patient Registry collected data on pwCF and SARS-CoV-2 infection to estimate incidence, describe clinical presentation and investigate factors associated with severe outcomes using multivariable analysis.

Results: Up to December 31, 2020, 26 countries reported information on 828 pwCF and SARS-CoV-2 infection.

Incidence of SARS-CoV-2 in people with cystic fibrosis in Europe between February and June 2020.

Background: Viral infections can cause significant morbidity in cystic fibrosis (CF). The current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic could therefore have a serious impact on the health of people with CF (pwCF).

Methods: We used the 38-country European Cystic Fibrosis Society Patient Registry (ECFSPR) to collect case data about pwCF and SARS-CoV-2 infection.

Lipid profile and left ventricular geometry pattern in obese children.

Background: Left ventricular hypertrophy (LVH) is an important risk factor for cardiovascular and all-cause mortality. Previous studies reported conflicting results concerning the relationship between serum lipid levels and left ventricular geometry pattern. We sought to explore the relationship between standard serum lipid profile measures with left ventricular geometry pattern in obese children.

Changing epidemiology of the respiratory bacteriology of patients with cystic fibrosis-data from the European cystic fibrosis society patient registry.

Background: Monitoring changes in the epidemiology of cystic fibrosis (CF) pathogens is essential for clinical research, quality improvement, and clinical management.

Methods: We analyzed data reported to the European Cystic Fibrosis Society Patient Registry (ECFSPR) from 2011 to 2016 to determine the overall and the age-specific annual prevalence and incidence of selected CF pathogens and their trends during these years. The ECFSPR collects data on three chronic infections: Pseudomonas aeruginosa (PsA), Burkholderia cepacia complex Species (BCC) and Staphylococcus aureus (SA), as well as on the occurrence of non-tuberculous mycobacteria (NTM) and Stenotrophomonas maltophilia (SM).

The future of paediatric and adolescent gynaecology in Europe.

Paediatric and Adolescent Gynaecology (PAG) is a subspecialty under the umbrella of Obstetrics and Gynaecology but linked to other branches of medicine including Paediatrics, Surgery, Endocrinology and Urology. Therefore future developments in clinical care and education requires a multidisciplinary approach combining aspects of all the above medical specialties, and also with inputs from Public Health, Genetics, Radiology and Psychology. A multidisciplinary collaboration among different specialists is as important as the establishment and adoption of standards in education, training and management.

Ovarian Preservation from Tumors and Torsions in Girls: Prospective Diagnostic Study.

Study Objective: To develop a new decision tree system (DTS) for the management of adnexal masses in prepubertal and adolescent girls, aimed to improve the distinction between benign and malignant masses, help preserve affected ovaries during surgery, and reduce the rate of surgical management of uncomplicated functional ovarian cysts.

Design: A prospective diagnostic study using clinical and ultrasound data collected for all patients younger than 19 years of age with adnexal masses managed between 2006 and 2015.

Setting: Mother and Child Health Institute of Serbia 'Dr Vukan Čupić' (Belgrade, Serbia).

Surgical treatment of severe laryngomalacia: Six month follow up.

Background: Laryngomalacia (LM) is the most common congenital anomaly of larynx that causes stridor in children. We evaluated the efficacy of epiglottic suture and laser epiglottopexy for treatment of infants with severe LM.

Methods: Surgical intervention was performed in 19 patients with severe LM, after the diagnosis was established using flexible laryngotracheobronchoscopy.

Giant Gartner duct cyst and elevated CA-125.

Background: Gartner duct cysts represent vestigial remnants of the caudal end of the mesonephric (Wolffian) ducts. They are often associated with ureteral and renal abnormalities. In most cases they are solitary, less than 2 cm in diameter.

Health-related quality of life and depression in Rett syndrome caregivers.

Background/aim: Rett syndrome (RTT) is a severe neurodevelopmental disorder primarily affecting females with an estimated incidence of 1:10,000-15,000 female births. Currently, there is no specific treatment that halts or reverses the progression of RTT. Therefore, management was mainly symptomatic, focussed on optimising patient's abilities.

Atypical presentation of cystic fibrosis--obese adolescent with hypertension and pseudo-Bartter's syndrome.

Introduction: Infants with cystic fibrosis may fail to thrive despite recommended caloric intake because of electrolyte disurbances caused by salt depletion resulting in hypochloremic metabolic alkalosis or pseudo-Bartter's syndrome. In most patients reported symptoms began in infancy, but it may be an initial presentation of disease in a previously healthy adolescent.

Case Report: A 15-year-old boy was admitted for evaluation of recurrent episodes of malaise associated with dehydration and acute renal insufficiency.

Early recurrent left atrial myxoma in a teenager with de novo mutation of Carney complex.

We report a case of an extremely early recurrence of left atrial myxoma in a 13-year-old girl. On hospital admission, the clinical presentation was of cerebral embolism with noticeable spotty skin pigmentation and hypertelorism. The left atrial myxoma originated from the roof of the left atrium.

Coagulation disturbances in paediatric patients with hepatic veno-occlusive disease after stem cells transplantation.

Introduction: Hepatic veno-occlusive disease (VOD) is a life threatening complication after stem cells transplantation (SCT). Its prediction, precise diagnosis and treatment remain unclear.

Objective: Our goals were to determine the incidence, outcome and changes in haemostatic parameters in patients with VOD.

Cystic echinococcosis in children - the seventeen-year experience of two large medical centers in Serbia.

Cystic echinococcosis (CE) is a public health problem in countries having such endemic areas. Epidemiological studies of CE, especially pediatric, are rare. The aim of this study was to evaluate epidemiological and clinical characteristics of CE in children in Serbia.

Torsion of malignant ovarian tumors in childhood and adolescence.

Aim: To investigate the frequency of torsion of malignant ovarian tumors in children and adolescents.

Methods: We evaluated all patients treated for adnexal torsion in a tertiary care referral pediatric institution during the last 20 years. Presentation, tumor markers and pathology reports were evaluated.
