Background To evaluate the effects of pressure levels on cerebral hemodynamics in premature infants receiving nasal continuous positive airway pressure (nCPAP) during the first 3 days of life. Methods Forty-four preterm infants treated with nCPAP were divided into two groups very preterm infants [gestational age 1 (GA1), GA less then 32 weeks, n = 24] and moderate/late preterm infants (GA2 group, GA 32-37 weeks, n = 20). During monitoring, pressure levels were set at 4 → 6 → 8 → 4 cmH2O, and cerebral hemodynamics was assessed by near-infrared spectroscopy (NIRS). Vital signs, peripheral oxygen saturation (SpO2) and transcutaneous carbon dioxide pressure (TcPCO2) were simultaneously recorded. Results Pressures of 4-8 cmH2O had no significant influence on cerebral hemodynamics, TcPCO2, SpO2 or other vital signs. The tissue oxygenation index (TOI), the difference between oxygenated hemoglobin (ΔHbO2) and deoxygenated hemoglobin (ΔHHb) (ΔHbD), and cerebral blood volume (ΔCBV) were all significantly positively correlated with gestational and post-natal age, with fluctuations being greater in the GA1 group. ΔHbD and ΔCBV were also significantly positively correlated with TcPCO2. Conclusions No significant differences were observed in cerebral hemodynamics when the nCPAP pressure was set to 4-8 cmH2O.Background Brainstem auditory evoked potentials (BAEP) provide an objective analysis of central nervous system function and development in infants. This study proposed to examine the relationship between infant BAEP values at age 6 months, and their neurodevelopment at age 2 years assessed by the mental development indices (MDI), a form of Bayley Scales of Infant Development. We hypothesized that in infants with BAEP values outside normal range, there may be neurodevelopmental delays, as shown by their MDI scores. Methods An exploratory investigation was conducted using preterm (28-36 weeks gestation; 95 cases) and term infants (≥37 weeks gestation; 100 cases) who were born with specific perinatal conditions. BAEP values were recorded in these infants from 1 to 8 months of age, and compared with MDI scores in these infants at age 2 years. A multivariate linear regressions model was performed to test the associations between all variables and MDI scores. Ruboxistaurin Stratified linear regression was used to test the interations should be encouraged to enrich neurodevelopment in premature babies with BAEP values outside the normal range.Autoimmune thyroid diseases (AITDs) which include Graves' disease (GD) and Hashimoto's thyroiditis (HT) as well as type 1 diabetes (T1D) are common autoimmune disorders in children. Many genes are involved in the modulation of the immune system and their polymorphisms might predispose to autoimmune diseases development. According to the literature genes encoding IL2RA (alpha subunit of Interleukin 2 receptor), IFIH1 (Interferon induced with helicase C domain 1) and CTLA-4 (cytotoxic T cell antigen 4) might be associated with autoimmune diseases pathogenesis. The aim of the study was to assess the association of chosen single nucleotide polymorphisms (SNPs) of IL2RA, IFIH1, and CTLA-4 genes in the group of Polish children with AITDs and in children with T1D. We analyzed single nucleotide polymorphisms (SNPs) in the IL2RA region (rs7093069), IFIH1 region (rs1990760) and CTLA-4 region (rs231775) in group of Polish children and adolescents with type 1 diabetes (n = 194) and autoimmune thyroid diseases (GD n = 170 SNPs revealed no association with AITDs in a group of Polish children and adolescents.Penile strangulation is a rare condition in children caused by circumferential constriction of the coronal sulcus by constricting material, commonly thin maternal hair. Vague presenting symptoms often makes diagnosis difficult, but delay in diagnosis can lead to a variety of severe complications including urethral injury and penile necrosis. Providers must have a high index of suspicion and carry out a careful examination to identify maternal hair strands that may bury deep within penile edema. We describe two cases of penile strangulation secondary to maternal hair strands that were successfully treated with thorough examination and division of the constricting hair in the emergency department. In both cases, presentation involved penile swelling and erythema which was noticed by caregivers. Once the diagnosis has been made, urgent treatment using depilatory cream or mechanical removal must occur, with urgent referral to specialists if unable to remove to constricting material. Caregivers must also be counseled on appropriate steps to prevent penile hair tourniquet syndrome. Devastating complications can be avoided by early recognition and proper management of the syndrome, but providers must have knowledge of the condition and a high index of suspicion.Postural tachycardia syndrome (POTS), characterized by chronic (≥6 months) orthostatic intolerance symptoms with a sustained and excessive heart rate increase while standing without postural hypotension, is common in children and adolescents. Despite the unclear pathogenesis of POTS, the present opinion is that POTS is a heterogeneous and multifactorial disorder that includes altered central blood volume, abnormal autonomic reflexes, "hyperadrenergic" status, damaged skeletal muscle pump activity, abnormal local vascular tension and vasoactive factor release, mast cell activation, iron insufficiency, and autoimmune dysfunction. A number of pediatric POTS patients are affected by more than one of these pathophysiological mechanisms. Therefore, individualized treatment strategies are initiated in the management of POTS, including basal non-pharmacological approaches (e.g., health education, the avoidance of triggers, exercise, or supplementation with water and salt) and special pharmacological therapies (e.g., oral rehydration salts, midodrine hydrochloride, and metoprolol). As such, the recent progress in the pathogenesis, management strategies, and therapeutic response predictors of pediatric POTS are reviewed here.Objectives Secondary mucoepidermoid carcinoma (MEC) of the head and neck is occasionally observed in childhood cancer survivors. The goal of this research was to compare the demographic and pathologic characteristics, as well as survival between primary and secondary MEC in children and adolescent patients. Methods Pediatric patients (younger than 19 years old) with surgically treated MEC of the head and neck were retrospectively enrolled at the Affiliated Children's Hospital of Zhengzhou University and divided into two groups based on their cancer history. Demographic, pathologic, and survival characteristics between the two groups were compared. The main study interests were recurrence-free survival (RFS), overall survival (OS), and disease-specific survival (DSS). Results The primary and secondary groups consisted of 63 and 15 patients, respectively. The two groups had similar distributions in terms of age, sex, tumor stage, neck lymph node stage, perineural invasion, lymphovascular invasion, p53, Bcl-2, proliferating cell nuclear antigen, carcinoembryonic antigen, and Ki-67 index.
