Chest X-ray(CXR) is commonly used as a first line imaging method to diagnose the reason of respiratory distress in NICUs.Lung ultrasound is a new diagnostic tool for lung imaging. We aimed to determine the decrease in the number of CXRs on the first day of life in newborns with respiratory distress,with the use of lung ultrasonography. From January 2019 to June 2020,104 newborn infants hospitalized in the NICU with respiratory distress on the first day of life enrolled in this study(ClinicalTrials.govIdentifier NCT04722016).We used ultrasound as the first line technique for lung imaging.CXR was taken to determine endotracheal tube and umbilical catheter position or if considered necessary by the physician in charge of the infant.We calculated decreased number of CXR for every patient and evaluated the estimated decrease in radiation exposure. 104 neonates with median 36 weeks(25–40)gestational age and birth weight 2410gr(600–4100) enrolled in the study.Seventy(67,3%)of these babies were male.In the study group,24(23,1 %)patients were diagnosed with respiratory distress syndrome(RDS),49(47,1 %) patients with transient tachypnea of newborn(TTN),27(26 %) with pneumonia,4(3,8 %)with congenital heart diseases.Lung ultrasonography were performed 210 times for all infants,but CXRs were performed a total of only 107 times.CXR wasnot taken in 27 of the patients with a diagnosis of TTN,in 2 of the patients with a diagnosis of congenital pneumonia,and in one of the patients with congenital heart disease.The rate of patients who have never had a chest x-ray was 28,8%.Conclusions:We observed that usage of lung ultrasonography decreased the number of chest X-ray and radiation exposure in newborns with respiratory distress.

Background:Intracranial lesions may affect the hypothalamo-hypophyseal axis and lead to some neuro-endocrinological dysfunctions (hyperphagia, sleep disorders and hormonal dysfunctions). There is a very limited number of studies about childhood obesity and intracranial lesions.Aims:To evaluate the incidence of intracranial lesions and its role in clinical symptoms and aetiology in cases with morbid obesity who have been admitted to the paediatric endocrinology department with this complaint.Study Design:Cross-sectional study.Methods:A total of 120 cases admitted to the paediatric endocrinology department with the complaint of morbid obesity between 2002 and 2015 were included in this study. A detailed history was taken and a physical examination was performed; biochemical, hormonal parameters were evaluated. Contrast dynamic magnetic resonance imaging was performed in order to visualize cranial pathologies.Results:An intracranial lesions was detected in 16.6% of the patients and 55% of these lesions were adenoma of the hypophysis. Prolactin levels were increased in six patients but front hypophyseal hormone levels were within normal range in the rest of the patients. Growth velocity of the patients was not affected.Conclusion:In our study, the incidence of intracranial lesions in children and adolescents with morbid obesity was much higher than in the normal population. According to this data, we are of the opinion that contrast dynamic magnetic resonance imaging is helpful in children with morbid obesity for the early detection of the mass before it causes any clinical or neurological symptoms and in the prevention of future complications.

Objective Amplitude-integrated electroencephalograph (aEEG) presents a valuable tool for functional brain maturation of preterm infants. However, the effect of enlightenment on functional brain maturation of premature infants has not been investigated. We aimed to do this with aEEG. Study Design A total of 32 infants, 30 to 35 gestational weeks, were involved in the study. They were randomly distributed into three groups in which different lighting protocols were applied. In group 1, the infants' incubators were covered for 24 hours. In group 2, the infants' incubators were open for 24 hours. In group 3, the infants' incubators were covered for 12 hours and open for another 12 hours. The infants are evaluated with aEEG recordings done on the 3rd (first measurement) and 10th days (second measurement) along with the Burdjalov scoring. Analysis of aEEG recordings was performed, based on sleep–wake cycles (SWCs), upper and lower margin amplitudes, narrowband and broadband of SWC, and bandwidth of SWC. Results At first, the narrowband lower amplitudes in group 1 were higher than those of the other groups (p = 0.042), but the difference was not significant in the second measurement (p = 0.110). The Burdjalov scores were higher in group 1 and group 3 on 10th day, though not statistically significant (p = 0.871). When the infants were re-evaluated according to the gestational weeks, the Burdjalov scores of the two groups less than 34 weeks (30–31 and 32–33 weeks) were similar, whereas 34 to 35 weeks were higher when compared with those of the two groups. Conclusion The difference observed between groups in terms of narrowband lower amplitude in the first measurement may reflect the effect of intrauterine environment rather than enlightenment at the same gestational age because it was made on the third day. However, the fact that all groups have similar results on day 10 suggests that other factors in the intensive care setting may diminish the effect of enlightenment. Burdjalov scores are associated with maturation, and high scores found in the 34- to 35-week group suggest that the 34-week maturation might be a threshold for SWC and development in our group sample.
