Background and objective Cryotherapy in interventional bronchoscopy is a new treatment modality, which has recently been made available for the paediatric airway. Lack of experience and safety concerns have led to hesitant adaptation. The aim of this study was to assess indications, success rates and complications of airway cryotherapy in children. Methods Bronchoscopists from medical centre performing cryotherapy in patients between 0 and 18 years were invited to participate in a prospective study based on an online questionnaire. Patient and participant data were collected between June 2020 and June 2021. Results A total of 69 cryotherapy procedures were performed in 57 patients a for three main indications: Biopsy (30), restoration of airway patency (23) and foreign body aspiration (16). The overall success rate was 93%, the remaining 7% were performed for foreign body removal and required a switch of technique. Restoration of airway patency was successfully applied in various pathologies, including mucus plugs, bronchial casts and post traumatic stenosis. The diagnostic yield of transbronchial biopsies was 96%. No severe complications were encountered; one pneumothorax following a cryobiopsy required a chest drain for 48 h. No child was admitted to intensive care or died from a procedural complication. Conclusion In this largest paediatric case collection to date, cryotherapy was safe and carried a high success rate. Cryobiopsy compares favourably to the widely used forceps biopsy and could replace it in the future. Paediatric bronchoscopists are encouraged to add cryotherapy to their armamentarium of airway interventions.
These findings suggest that the most common phenotype of pediatric OSA has a negative effect on the structure of sleep, but other clinical studies are needed to confirm this result.
BackgroundImpairment in cardiovascular autonomic regulation participates in the onset and maintenance of primary hypertension.ObjectiveThe aim of the present study was to evaluate cardiac autonomic control using long-term heart rate variability (HRV) analysis in adolescents with primary hypertension.Subjects and methodsTwenty two adolescent patients with primary hypertension (5 girls/17 boys) aged 14-19 years and 22 healthy subjects matched for age and gender were enrolled. Two periods from 24-hour ECG recording were evaluated by HRV analysis: awake state and sleep. HRV analysis included spectral power in low frequency band (LF), in high frequency band (HF), and LF/HF ratio.ResultsIn awake state, adolescents with primary hypertension had lower HF and higher LF and LF/HF ratio. During sleep, HF was lower and LF/HF ratio was higher in patients with primary hypertension.ConclusionsA combination of sympathetic predominance and reduced vagal activity might represent a potential link between psychosocial factors and primary hypertension, associated with increased cardiovascular morbidity.
We report the first case of acute meningitis caused by a rare, atypical pathogen. An 11-month-old infant was admitted to hospital with clinical symptoms typical of acute meningitis. Cerebrospinal fluid analysis revealed an elevated neutrophil cell count and high proteins. Microbiological examination of the fluid confirmed an atypical cause of meningitis--Staphylococcus intermedius. Antibiotic therapy with cefotaxime was successful and the child made a full recovery.
Background: Considering a dramatic increase in the incidence of type 1 diabetes (T1D) worldwide, current research focuses on complex etiology of T1D where immune system, environmental and genetic factors play a significant role. Glutathione S-transferase family of enzymes protects tissue from oxidative damage which is discussed in the context of T1D. The aim of the study was to investigate an association of glutathione S-transferase mu 1 (GST M1) and glutathione S-transferase theta 1 (GST T1) polymorphisms with type 1 diabetes. Methods: 163 children, 116 with type 1diabetes and 47 healthy controls, at the age 6-19 years were enrolled to the study. Basic anthropometric, biochemical parameters and GST T1 diabetes and M1 polymorphisms were established in each subject. Results: Subjects with T1D had significantly lower concentration of uric acid compared to the healthy subjects (212.85±57.10 µmol/l vs. 269.57±72.53; p<0.001). GST T1 null genotype was more frequent in patients with diabetes compared to the healthy controls (36.2% vs. 21.3%) and represented 2.1-fold increased risk of T1D of borderline statistical significance (OR=2.1; 95% CI=0.949-4.648; p=0.06). GST T1 null/M1 wild genotype combination was more frequent in patients with diabetes (25.9% vs. 10.6%) and represented 2.9-fold increased risk for T1D development (OR=2.93; 95% CI=1.061-8.095; p=0.032). Conclusion: The study indicates that GST T1 null genotype and GST T1 null/M1 wild combination could be considered a risk factor for type 1 diabetes development in Slovak children and adolescents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
