The childhood interstitial lung diseases (chILD) Turkey registry (chILD-TR) was established in November 2021 to increase awareness of disease, and in collaboration with the centers to improve the diagnostic and treatment standards. Here, the first results of the chILD registry system were presented. In this prospective cohort study, data were collected using a data-entry software system. The demographic characteristics, clinical, laboratory, radiologic findings, diagnoses, and treatment characteristics of the patients were evaluated. Clinical characteristics were compared between two main chILD groups ((A) diffuse parenchymal lung diseases (DPLD) disorders manifesting primarily in infancy [group1] and (B) DPLD disorders occurring at all ages [group 2]). There were 416 patients registered from 19 centers. Forty-six patients were excluded due to missing information. The median age of diagnosis of the patients was 6.05 (1.3-11.6) years. Across the study population (n = 370), 81 (21.8%) were in group 1, and 289 (78.1%) were in group 2. The median weight z-score was significantly lower in group 1 (- 2.0 [- 3.36 to - 0.81]) than in group 2 (- 0.80 [- 1.7 to 0.20]) (p < 0.001). When we compared the groups according to chest CT findings, ground-glass opacities were significantly more common in group 1, and nodular opacities, bronchiectasis, mosaic perfusion, and mediastinal lymphadenopathy were significantly more common in group 2. Out of the overall study population, 67.8% were undergoing some form of treatment. The use of oral steroids was significantly higher in group 2 than in group 1 (40.6% vs. 23.3%, respectively; p = 0.040).   Conclusion: This study showed that national registry allowed to obtain information about the frequency, types, and treatment methods of chILD in Turkey and helped to see the difficulties in the diagnosis and management of these patients. What is Known: • Childhood interstitial lung diseases comprise many diverse entities which are challenging to diagnose and manage. What is New: • This study showed that national registry allowed to obtain information about the frequency, types and treatment methods of chILD in Turkey and helped to see the difficulties in the diagnosis and management of these patients. Also, our findings reveal that nutrition should be considered in all patients with chILD, especially in A-DPLD disorders manifesting primarily in infancy., (© 2023.

Background: The coronavirus disease-2019 pandemic has contributed to work-related psychosocial risks in healthcare workers., Aims: To evaluate the perceived need for mental health services and related factors in Turkish healthcare workers practicing in pandemic hospitals., Study Design: Cross-sectional study., Methods: Data were collected from face-to-face interviews with healthcare workers at 19 pandemic hospitals in 13 provinces between September and November 2021. The study survey included the evaluation of the perceived need for and utilization of mental health services in the previous year, as well as sociodemographic, health-related, and work-related characteristics, the General Health Questionnaire-12, the World Health Organization Quality of Life-BREF (WHOQoL-BREF) questionnaire, and the Fear of coronavirus disease-2019 scale (FCV-19S)., Results: Of 1,556 participants, 522 (33.5%) reported a perceived need for mental health services, but only 133 (8.5%) reported receiving these services. Multiple logistic regression analysis of the perceived need for mental health services revealed significant relationships with lower age, female sex, being a current smoker, having a chronic disease, having a mental disorder, coronavirus disease-2019 contact within the last three months in settings other than the home or workplace, a positive coronavirus disease-2019 vaccination history, being a physician, being a non-physician healthcare professional, and coronavirus disease-2019 contact within the last three months at work. After adjustment for these characteristics, higher General Health Questionnaire-12 and FCV-19S scores and lower WHOQoL-BREF domain scores were related to the perceived need for mental health services in logistic regression analyses., Conclusion: The findings indicate a substantial need for mental health services amongst Turkish healthcare workers during the pandemic and outline participants’ characteristics regarding high-priority groups for the intervention. Future research may focus on developing actions and evaluating their efficiency.

We present a unique case of 6th nerve palsy following accidental durotomy in endoscopic lumbar spine surgery, which has not been reported in the literature before. A 72- year-old female patient was admitted to our outpatient clinic complaining of right leg pain for 6 months. A 4/5 motor paresis was observed on her right toe with a positive Lasegue test at 45°. On her magnetic resonance imaging (MRI), a L5-S1 disc herniation was detected. The patient was planned for percutaneous endoscopic interlaminar disc surgery. The extruded disc was adherent to the dura. During removal, a dural tear was observed. She was relieved of her right leg pain immediately after surgery, but after 30 min postoperatively, she complained of double vision with left abducens nerve paralysis. On cranial MRI, no abnormality could be observed. Intravenous fluids were administered and the paralysis resolved on the postoperative 24th hour. The patient was discharged from the hospital and did not show any complaints on her follow-ups. A 6th nerve palsy can be caused due to alterations of intracranial pressure or mechanic injury. We believe that the durotomy following removing of the disc fragment caused a rapid drainage of CSF, leading to intracranial hypotension and injury of the abducens nerve. Intracranial pressure should be monitored perioperatively and brisk deteriorations has to result in immediate finishing of the surgery to avoid further secondary damage., (© 2022 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Objective: COVID-19 pandemic has put a tremendous amount of stress on people, which can negatively affect nursing. Previous studies showed that perceived stress and cortisol levels in the postpartum period correlate with the LATCH scores, which is a simple tool to assess the pattern of nursing. Likewise, greater prenatal anxiety was associated with a shorter breastfeeding duration. We aimed to evaluate whether pregnant women were under extra stress due to the COVID-19 pandemic and if this stress affected their breastfeeding patterns and anthropometric measures of the neonates., Methods: Pregnant women giving birth to healthy neonates were included. Coronavirus Anxiety Scale (CAS) and Beck Anxiety Inventory (BAI) were used to assess the anxiety levels of the mothers, and LATCH breastfeeding assessment tool was used to assess the nursing. The results of these scales and anthropometric measures of the neonates were recorded., Results: Only one mother showed coronavirus-specific anxiety. Therefore, further analysis was done based on the Beck Anxiety (BA) levels of the mothers. CAS and BA scores were positively correlated ( p <0.001, r=0.444), indicating that coronavirus-specific anxiety increased with increasing general anxiety. None of the variables changed depending on the anxiety levels of the mothers, except for the % weight gain at day five ( p =0.020, r=-0.248). Even though anxiety seemed to show a small effect on weight loss during the first neonatal days, percent weight gain results did not seem to correlate with the anxiety levels in later stages (first month of life). Furthermore, LATCH scores of the infants on day one were positively correlated with BA scores of the mothers ( p =0.045, r=0.175)., Conclusion: COVID-19 seemed to have no additional effect on the stress levels of the mothers. The more the mothers have anxiety, the more they may stress about the well-being of their infants, which can improve their nursing pattern., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Infectious Diseases and Clinical Microbiology.)

Background: Pulmonary embolism is a clinical condition caused by the obstruction of the pulmonary artery and its branches with endogenous, exogenous embolism, or local thrombus formation. It is a rare but potentially life-threatening event in the pediatric population. Pediatric pulmonary embolism has many unknown characteristics., Aims: To evaluate clinical features, genetic and acquired risk factors, diagnostic imaging, and treatment strategies with long-term results in children with pulmonary embolism., Study Design: A retrospective multicenter clinical trial., Methods: Patients aged 0-18 years who were diagnosed with pulmonary embolism with computed tomography pulmonary angiography (CTPA) findings (intraluminal filling defect in the lobar or main pulmonary artery) in 3 university hospitals between 2006 and 2021 were included in the study. A form was created for data standardization, and variables were collected retrospectively through medical record review. In addition to the features given above, we also evaluated in situ pulmonary artery thrombosis (ISPAT) and patients' Wells scores. Follow-up CTPA results were evaluated for patient response to treatment. Complete recovery means that there were no lesions, incomplete recovery if there was still embolism, and no response if there was no change., Results: Twenty-four patients (female:13, male:11) were included in the study. The mean age was 13.5 years. All patients but one had at least one or more genetic or acquired risk factors. Factor V Leiden mutation (16.6%) was the most common genetic risk factor. Six of 16 patients with Doppler ultrasonography were diagnosed with ISPAT because there was no sign of thromboembolic thrombosis. Nine (41.6%) patients had a Wells score of >4 (pulmonary embolism clinically strong), and 15 (58.4%) patients scored <4 (pulmonary embolism clinically likely weak), indicating that an alternative diagnosis was more likely than pulmonary embolism (sensitivity %37.5). The mean follow-up period was 23 (±17) months. Complete and incomplete recovery was observed in 15 (62.5%) and 7 (29.1%) patients, respectively, among the patients who underwent follow-up evaluation. No response was obtained in 2 patients (8.3%) who died., Conclusion: The Wells scoring system seems insufficient to diagnose pulmonary embolism in children and should be improved by adding new parameters. ISPAT may be more common in children with congenital heart disease and systemic disease.

The exact immunological mechanisms of post infectious bronchiolitis obliterans (PIBO) in childhood are not fully known. It has been shown that the inflammasome and IL-18 pathway play important roles in the pathogenesis of lung fibrosis. We aimed to investigate the role of caspase-1, IL-18, and IL-18 components in PIBO. From January to May 2020, children with PIBO, children with history of influenza infection without PIBO, and healthy children were asked to participate in the study in three pediatric pulmonology centers. Serum caspase-1, IL-18, IL-18BP, IL-18R, and INF-γ levels were measured by ELISA and compared between the 3 groups. There were 21 children in the PIBO group, 16 children in the influenza group, and 39 children in the healthy control group. No differences in terms of age and gender between the 3 groups were found. IL-18 and IL-18BP levels were higher in the healthy control group (p = 0.018, p = 0.005, respectively). IL-18R was higher in the PIBO group (p = 0.001) and caspase-1 was higher in the PIBO and influenza group than the healthy control group (p = 0.002). IFN-γ levels did not differ between the 3 groups. IL-18BP/IL-18 was higher in the influenza group than the PIBO group and the healthy control group (p = 0.003)., Conclusions: Caspase-1 level was increased in patients with PIBO which suggests that inflammasome activation may have a role in fibrosis; however, IL-18 level was found to be low. Mediators other than IL-18 may be involved in the inflammatory pathway in PIBO. Further immunological studies investigating inflammasome pathway are needed for PIBO with chronic inflammation., What Is Known: • Post infectious bronchiolitis obliterans (PIBO) is a rare, severe chronic lung disease during childhood which is associated with inflammation and fibrosis which lead to partial or complete luminal obstruction especially in small airways. • The exact immunological mechanisms of PIBO in childhood are not fully known., What Is New: • Inflammasome activation persists even years after acute infection and may play a role in fibrosis in PIBO. • Mediators other than IL-18 may be involved in these inflammatory pathway., (© 2022.

This review aimed to highlight some important points derived from the presentations of the European Respiratory Society 2021 Virtual International Congress by a committee formed by the Early Career Task Group of the Turkish Thoracic Society. We summarized a wide range of topics including current developments of respiratory diseases and provided an overview of important and striking topics of the congress. Our primary motivation was to give some up-to-date information and new developments discussed during congress especially for the pulmonologists who did not have a chance to follow the congress. This review also committed an opportunity to get an overview of the newest data in the diverse fields of respiratory medicine such as post-coronavirus disease 2019, some new interventional and technologic developments related to respiratory health, and new treatment strategies.

Background: Cystic fibrosis, a pulmonary disease which is an autosomal recessive, inherited, multisystemic genetic disease commonly seen in the Caucasian race, is the most frequent cause of mortality and morbidity. So far, more than 2000 disease-causing gene variants have been found and this number has been increasing with the studies conducted. Although there is not yet enough data that include the Turkish population, the recent increase of studies is noteworthy., Aims: To discover the genetic variation in patients diagnosed with cystic fibrosis in the Central Anatolian region., Study Design: Cross-sectional study., Methods: The study was carried out in the Central Anatolian region in 3 pediatric pulmonology departments (Kayseri, Konya, and Ankara) in Turkey between July 2014 and December 2017. The Sanger and Next Generation Sequence analyses were used for exon and exon-intron boundaries in the cystic fibrosis transmembrane conductance regulatory (CFTR) gene, and in selected patients, mutation analysis was performed using the Multiplex Ligation-dependent Probe Amplification technique for large deletions and duplications., Results: CFTR gene analysis was performed for 316 patients and 215 of them were genetically diagnosed with cystic fibrosis. Sixtythree different variants were defined in these patients and 7 of these were large deletions/duplications detected with the MLPA method. The most frequent variants were F508del (29.6%), G85E (8.2%), N1303K (8.2%), Y515* (7.5%), and G542* (3.4%)., Conclusion: Using sequencing and Multiplex Ligation-dependent Probe Amplification methods, the identification of seven new mutations that were not previously reported in the literature contributes to a better understanding of the heterogeneous nature of CFTR mutations in the Turkish population. When no mutations are detected (pathogenic/probably pathogenic) in clinically compatible cases, Multiplex Ligationdependent Probe Amplification analysis contributes significantly to the diagnosis.

Aims: In clinical practice, birth weight reference percentiles for singletons are used to evaluate twin births. The utilization of singleton reference percentiles for twins is not appropriate as they experience different growth trajectories. However, Turkey still lacks such references. Our aim was to create gestational age-specific birth weight references for female and male Turkish twins., Materials and Methods: This is a hospital-based, multi-centered, retrospective study. In total, 2544 live-born twins between 2010 and 2019 were included in the study. Gestational age, birth weight, mode of delivery, gender, birth order, chorionicity, maternal age, pregnancy resulting from assisted reproduction techniques, APGAR (Appearance, Pulse, Grimace, Activity, and Respiration) score at 5 minutes, admission to the neonatal intensive care unit (NICU), length of stay in NICU, and death during the NICU stay were recorded., Results: Smoothed reference curves for birth weight by gestational age and separate tables for female and male twin neonates for the 3 rd , 10 th , 50 th , 90 th , and 97 th percentiles from 26 to 39 weeks of gestational age were constructed. Overall neonatal and infant mortality rates during NICU stay in our twin cohort were 12/1000 and 16/1000, respectively., Conclusion: Twin-specific birth weight nomograms could be helpful as a reference for clinicians to identify high-risk neonates and fetuses who need specialized care. However, further studies with larger series are urgently needed for validation and use of these nomograms in clinical practice., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (© Copyright 2021 by The Turkish Archives of Pediatrics.)

Background: Healthcare-acquired infections (HAIs) in the neonatal period cause substantial morbidity, mortality, and healthcare costs. Our purpose was to determine the prevalence of HAIs, antimicrobial susceptibility of causative agents, and the adaptivity of the Centres for Disease Control and Prevention (CDC) criteria in neonatal HAI diagnosis., Methods: A HAI point prevalence survey was conducted in the neonatal intensive care units (NICUs) of 31 hospitals from different geographic regions in Turkey., Results: The Point HAI prevalence was 7.6%. Ventilator-associated pneumonia (VAP) and central line-associated bloodstream infections (CLABSI) and late onset sepsis were predominant. The point prevalence of VAP was 2.1%, and the point prevalence of CLABSI was 1.2% in our study. The most common causative agents in HAIs were Gram-negative rods (43.0%), and the most common agent was Klebsiella spp (24.6%); 81.2% of these species were extended spectrum beta-lactamase (ESBL) (+). Blood culture positivity was seen in 33.3% of samples taken from the umbilical venous catheter, whereas 0.9% of samples of peripherally inserted central catheters (PICCs) were positive. In our study, 60% of patients who had culture positivity in endotracheal aspirate or who had purulent endotracheal secretions did not have any daily FiO2 change (p = 0.67) and also 80% did not have any increase in positive end-expiratory pressure (PEEP) (p = 0.7). On the other hand, 18.1% of patients who had clinical deterioration compatible with VAP did not have endotracheal culture positivity (p = 0.005)., Conclusions: Neonatal HAIs are frequent adverse events in district and regional hospitals. This at-risk population should be prioritized for HAI surveillance and prevention programs through improved infection prevention practices, and hand hygiene compliance should be conducted. CDC diagnostic criteria are not sufficient for NICUs. Future studies are warranted for the diagnosis of HAIs in NICUs., Competing Interests: Declaration of competing interest We declare that there are no competing financial interests in relation to the work described., (Copyright © 2021.

Objective: To determine if near-infrared spectroscopy (NIRS), which is easier to obtain than Doppler ultrasonography (USG), may be used in accordance with Doppler USG to provide additional data for assessment of organ blood flow velocities in preterm infants with hemodynamically significant PDA. Study design: Thirty-one infants who were treated with ibuprofen for closure of PDA were monitored continuously with NIRS. Cerebral, mesenteric, and renal arterial blood flow velocities were measured with Doppler USG before and after the treatment. Results: While cerebral, mesenteric, and renal fractional oxygen extraction (FTOE) measurements decreased significantly ( p  = .042, p  < .001, p  < .001, respectively), NIRS measurements ( p  = .016, p  < .001, p  < .001, respectively) and mean blood flow velocities ( p  = .003, p  = .011, p  = .002, respectively) increased significantly after the treatment. There was a significant correlation between pretreatment cerebral and mesenteric FTOE and resistive index (RI) values ( r  = 0.45, p  = .01, and r  = 0.46, p  = .01, respectively). However, no correlation was observed between renal FTOE values and renal RI ( r  = 0.33, p  = .06). Posttreatment cerebral, renal, and mesenteric FTOE values correlated positively with corresponding RI ( r  = 0.41, p  = .02; r  = 0.39, p  = .02; r  = 0.65, p  < 01; respectively). Pretreatment and posttreatment cerebral, mesenteric, and renal FTOE values and arterial mean velocities were inversely correlated (pretreatment: r  = 0.69, p  < .01; r  = 0.72, p  < .01; r  = 0.77, p  < .01; posttreatment: r  = 0.54, p  = .01; r  = 0.69, p  < .01; r  = 0.38, p  = .01; respectively). Conclusion: As Doppler and NIRS measurements correlated significantly, we concluded that NIRS might be used in monitoring organ blood flow in preterm infants with PDA, which may provide additional data for management of this condition.

Objective: To evaluate the correlation between total serum and transcutaneous bilirubin and to determine the reliability of transcutaneous bilirubinometry for screening and monitoring of neonatal jaundice among preterms., Study Design: Ninety nine infants with gestational ages ≤34 weeks were prospectively enrolled. Babies were classified into three groups as; 24-28, 29-31, and 32-34 weeks. Total serum bilirubin and simultaneous transcutaneous bilirubin were measured before the onset of phototheraphy, during and at 24 h after discontinuing phototherapy., Results: Total serum bilirubin significantly correlated with transcutaneous bilirubin in the whole cohort (r = 0.867, p < 0.001) and in each group before, during and after phototheraphy. Hypotension was the only variable which effects the difference between two methods at postnatal first day of life (p = 0.039)., Conclusion: Transcutaneous bilirubin levels were highly correlated with total serum bilirubin levels even in 24-28 GW babies. Transcutaneous bilirubin may be useful for screening and monitoring of jaundice in very preterm newborns.

Background: Cystic fibrosis (CF) care has been implemented in Turkey for a long time; however, there had been no patient registry. For this purpose, the Turkish National CF Registry was established. We present the first results of registry using data collected in 2017., Methods: The data were collected using a data-entry software system, which was accessed from the internet. Demographic and annually recorded data consisted of 15 and 79 variables, respectively., Results: There were 1170 patients registered from 23 centers; the estimated coverage rate was 30%. The median age at diagnosis was 1.7 years (median current age: 7.3 years); 51 (4.6%) patients were aged over 18 years. Among 293 patients who were under 3 years of age, 240 patients (81.9%) were diagnosed through newborn screening. Meconium ileus was detected in 65 (5.5%) patients. Genotyping was performed in 978 (87.4%) patients and 246 (25.2%) patients' mutations were unidentified. The most common mutation was deltaF508 with an allelic frequency of 28%, followed by N1303K (4.9%). The median FEV1% predicted was 86. Chronic colonization with Pseudomonas aeruginosa was seen in 245 patients. The most common complication was pseudo-Bartter syndrome in 120 patients. The median age of death was 13.5 years in a total of 15 patients., Conclusions: Low coverage rate, lack of genotyping, unidentified mutations, and missing data of lung functions are some of our greatest challenges. Including data of all centers and reducing missing data will provide more accurate data and help to improve the CF care in Turkey in the future., (© 2019 Wiley Periodicals, Inc.)

Jaundice is one of the most common problems in the newborn. It is generally accepted as a physiologic condition; most cases are benign and transient. However, in a small portion of jaundiced newborn infants, serum bilirubin concentrations increase to a level at which irreversible brain damage can occur. The timely diagnosis and management of severe hyperbilirubinemia is essential to prevent acute bilirubin encephalopathy and kernicterus. Kernicterus still occurs although it is almost always preventable. The focus of this guideline is to reduce the incidence of severe hyperbilirubinemia and bilirubin encephalopathy. Therefore, a system-based approach using the recommendations of this guideline should be implemented in all birthing facilities and continued in ambulatory care of the newborn infants., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Background: Data describing how laryngeal cancer affects oxidative stress markers and antioxidants are limited. This study investigated serum antioxidant enzyme activities and oxidative stress markers before and after laryngectomies in patients with laryngeal cancer., Methods: A total of 29 patients with laryngeal cancer and 25 healthy control subjects were enrolled. Serum malondialdehyde (MDA) levels and superoxide dismutase (SOD), glutathione peroxidase (GSHPx), catalase (CAT), paraoxonase (PON), and arylesterase activities were measured spectrophotometrically. Blood samples were obtained from each patient just before surgery and 1 month after a laryngectomy., Results: The serum PON, arylesterase, CAT, SOD, and GSHPx activities were significantly decreased (all p < 0.001) and serum MDA levels were significantly increased (p < 0.001) in patients with laryngeal cancer, compared with control subjects. In laryngeal cancer patients, the serum GSHPx and arylesterase activity levels increased significantly following laryngectomies (both p < 0.001), whereas the MDA levels decreased significantly (p = 0.007)., Conclusion: In patients with laryngeal cancer, the oxidant/antioxidant balance shifted toward oxidative stress. In addition, following laryngectomies, laryngeal cancer patients had increases in serum antioxidant enzyme activities and decreases in oxidative stress markers., (Copyright © 2018.

Background: The aim of this study was to evaluate the relationship between umbilical cord blood interleukin (IL)-6 concentration and preterm morbidity and mortality in premature infants born with fetal inflammatory response syndrome (FIRS)., Methods: This prospective, observational study included 84 preterm infants with a gestational age of 24-36 weeks who had been admitted to the neonatal intensive care unit (NICU). FIRS was defined as umbilical cord blood IL-6 > 11 pg/mL. In premature infants with FIRS, morbidities (multiple organ failure [MOF], respiratory distress syndrome [RDS], patent ductus arteriosus, intraventricular hemorrhage, bronchopulmonary dysplasia, retinopathy of prematurity) and death were evaluated. Critical umbilical cord blood IL-6 concentrations for the development of RDS, death, and for MOF were determined in premature infants with FIRS., Results: Fifty-two infants with IL-6 concentration > 11 pg/mL constituted the FIRS group. Thirty-two infants without FIRS served as a control group. RDS, MOF, and mortality were significantly higher in the FIRS group (P = 0.001, P = 0.001, and P = 0.005, respectively). Umbilical cord blood IL-6 concentration > 26.7 pg/mL in the FIRS group was found to be predictive of RDS, with 70% sensitivity and 85% specificity. Umbilical cord blood IL-6 concentration > 37.7 pg/mL was found to be predictive of death, with 78.6% sensitivity and 60% specificity. The predictive value of IL-6 for the development of MOF was 17.5 pg/mL, with 91% sensitivity and 66% specificity., Conclusions: Umbilical cord blood IL-6 concentration > 26.7, 37.7, and 17.5 pg/mL in premature infants with FIRS was found to be predictive for RDS, death, and MOF, respectively., (© 2015 Japan Pediatric Society.)

Background: Late preterm infants have increased rates of morbidity and mortality compared to term infants. Determining the risk factors in these infants leads to more comprehensive preventive and treatment strategies., Aims: Our aim was to analyse the morbidity rates such as respiratory system diseases, infections, congenital anomalies, hypoglycemia and hematologic abnormalities and mortality rates in a large group of patients at a referral center., Study Design: Retrospective cross-sectional study., Methods: Medical records of late preterm and term infants who were managed at the referral center were analysed., Results: 41752 births were analysed in 3 years. 71.9% of all births were between 37-42 gestational weeks (i.e. term) and 16.1% were between 34-37 weeks (i.e. late preterm). Compared to term infants, late preterm infants had increased rates of short-term problems. The rate of mortality increased with decreased gestational age. The duration of hospitalization was significantly higher in the smallest late preterm infants., Conclusion: This study demonstrated the need that late preterm infants who have higher risk for morbidity and mortality, compared to term infants require close monitoring. The rate of mortality and hospitalization increased with decreased gestational age.

Objective: Thrombocytopenia is a very common problem in neonatal intensive care unit whose only specific treatment is platelet (PLT) transfusion which has well-known risks. Our aim is to test whether using PLT mass-based transfusion guideline would result in fewer transfusions or not., Methods: One hundred neonates with PLT count <100,000/μl were randomized into two groups: Group 1 (n = 50) was transfused according to PLT count-based guideline, whereas Group 2 (n = 50) was transfused according to PLT mass-based guideline. Subjects receiving one or more PLT transfusions and total number of PLT transfusions, hemorrhages, morbidity and mortality in both groups were recorded., Results: Demographic characteristics, PLT counts of the infants and clinical conditions associated with thrombocytopenia in both groups were not different. There was no reduction in the number of subjects receiving PLT transfusions (54% in Group 1, 50% in Group 2; p = 0.69) and in the number of PLT transfusions per infant (0.82 ± 1.13 versus 0.8 ± 1.23; p = 0.95). There was also no difference with respect to bleeding, morbidity and mortality between the groups., Conclusion: Transfusion according to PLT mass or PLT count-based guideline does not seem to influence number of transfusions or the number of infants who were transfused.

Aim: Neonatal sepsis is an important cause of mortality and morbidity in newborns. The causative agents may be different in different units and may change in time. It was aimed to examine the microbiological agents leading to sepsis, clinical features and antibiotic resistances in babies with sepsis hospitalized in our unit in a two-year period., Material and Methods: The clinical features, microbiological and laboratory results, antibiotic resistance patterns and mortality rates of the newborns with sepsis followed up in our unit between 2010 and 2011 were examined in the patient record system., Results: 351 babies diagnosed with sepsis among 3219 patients hospitalized in the neonatal intensive care unit were included in the study. The mean gestational age was found to be 30.1±4.1 weeks, the mean birth weight was found to be 1417.4±759.1 g and the mean hospitalization time was found to be 43.6±34.4 days. Blood cultures were found to be positive in 167 (47.6%) patients, urine cultures were found to be positive in 6 (7.1%) patients and cerebrospinal fluid cultures were found to be positive in 34 (9.6%) cases. Candida grew in 5 patients (2 patients with early-onset sepsis and 3 patients with late-onset sepsis). The most common cause of sepsis was found to be staphylococci (coagulase negative staphylococcus was found in 65 patients (51%) and Staphylococcus aureus was found in 38 patients (39%). 49.6% (n=63) of the gram positive bacteriae and 60% (n=21) of the gram negative bacteriae were resistant to antibiotics. Six (7.1%) of the patients who were infected with these bacteriae were lost. In total 24 babies were lost because of sepsis. The bacteriae which caused to mortality with the highest rate included E. coli, coagulase negative staphylocicci, S. aureus and Klebsiella. Low birth weight, mechanical ventilation and parenteral nutrition were found to be significant risk factors in terms of mortality., Conclusions: Staphylococci were found to be the most common agents in neonatal sepsis. Low birth weight, mechanical ventilation and parenteral nutrition are significant risk factors in terms of mortality.

Background: To investigate the efficacy and safety of recombinant human granulocyte colony-stimulating factor, recombinant human granulocyte-macrophage colony-stimulating factor (rhG-CSF) to treat sepsis in neutropenic preterm infants., Methods: Fifty-six neutropenic preterm infants with suspected or culture-proven sepsis hospitalized in Zeynep Kamil Maternity and Children's Educational and Training Hospital, Kozyatağı/Istanbul, Turkey between January 2008 and January 2010 were enrolled. Patients were randomized either to receive rhG-CSF plus empirical antibiotics (Group I) or empirical antibiotics alone (Group II). Clinical features were recorded. Daily complete blood count was performed until neutropenia subsided. Data were analyzed using SPSS version 11.5., Results: Thirty-three infants received rhG-CSF plus antibiotic treatment and 23 infants received antibiotic treatment. No drug-related adverse event was recorded. Absolute neutrophil count values were significantly higher on the 2(nd) study day and 3(rd) study day in Group I. Short-term mortality did not differ between the groups., Conclusion: Treatment with rhG-CSF resulted in a more rapid recovery of ANC in neutropenic preterm infants. However, no reduction in short-term mortality was documented., (Copyright © 2014. Published by Elsevier B.V.)

Quantitative ultrasound (QUS) measurement of tibial speed of sound (SOS) can be used to determine bone strength. Children conceived with assisted reproduction treatments (ART) are taller than naturally conceived (NC) children, so we hypothesized that these infants would have higher SOS levels than NC infants. Thirty-seven ART (ART group) and 51 NC neonates (NC group) were included in the study. Tibial initial SOS (iSOS) was measured within 96 hours of birth using QUS. Measurements were performed weekly until the infant was discharged from the hospital. The iSOS levels of the ART group (2823.41±110.8 m/sec) were lower than those of the NC group (2917.14±145.6 m/sec) (p=0.001). A decrease in SOS levels was observed in 39 of 53 infants who had serial scans. The difference in SOS levels between the first and last scan was significant (p<0.02). In vitro manipulation during the periconceptual period can result in metabolic alterations in bone mineral content. Contrary to our null hypothesis, bone SOS of infants in the ART group was found to be lower than in the NC group. Moreover, bone SOS decreases in early postnatal life. This result emphasizes the fact that even with advances in nutritional care, the ex utero environment remains a poor substitute for in utero development.

Objective: Surfactant treatment in the early hours of life significantly decreases the rates of death and air leak, and increases survival without bronchopulmonary dysplasia (BPD) in preterm infants. We aimed to compare the impact of early surfactant (ES) administration to late selective (LS) treatment on neonatal outcomes in preterm infants., Methods: All preterm infants between 25 and 30 wks gestational age and who were not entubated in the delivery room and did not have any major congenital malformation or perinatal asphyxia were randomized to ES treatment (200 mg/kg Curosurf® administration in 1 hour after birth) or LS treatment (200 mg/kg Curosurf®administration in the first 6 h of life if needed). The patients were treated by nasal continuous positive airway pressure (nCPAP) treatment regardless of the surfactant requirement. Outcomes were the necessity of mechanical ventilation, nCPAP duration, the oxygen requirement duration, the rates of BPD, retinopathy of prematurity (ROP) and mortality, and the assessment of the following situations; (pneumothorax, patent ductus arteriosus (PDA), necrotizing enterocolitis (NEC), and intraventricular hemorrhage (IVH) ≥ grade III)., Results: Among 159 infants enrolled in the study, 79 were randomized to ES and 80 to LS treatment groups. Thirty-five patients (44%) in the LS treatment group needed surfactant administration. Necessity of second dose surfactant administration was 8.9% in the ES treatment group. Although necessity of mechanical ventilation, nCPAP duration, oxygen need duration, rates of PDA, NEC, BPD, ROP stage >3 and mortality did not show a significant difference between groups, the ES treatment group had lower rates of pneumothorax and IVH ≥ grade III when compared to the LS treatment group., Conclusions: ES treatment decreases IVH (≥ grade III) and pneumothorax rates but does not have any effect on BPD when compared to LS.

Background: Sepsis is an important cause of neonatal death and perinatal brain damage, particularly in preterm infants. It is thought that activation of the inflammatory cascade triggered by cytokine might play a role in the pathogenesis of sepsis. Recent evidence supports a role for resistin in inflammation. There are no data in the literature on resistin levels of premature newborns with sepsis, which can also cause inflammatory response. The objective of this study was to evaluate whether resistin can be used as an indicator in neonatal sepsis of preterm babies., Materials and Methods: Forty-three premature newborns considered to have sepsis were included in the study. Forty-three gestational and postnatal age- and sex-matched premature newborns without premature prolonged rupture of membrane or sepsis served as controls., Results: The median resistin and interleukin-6 (IL-6) levels of the premature babies with sepsis were 85.9 ng/mL and 342.7 pg/mL, respectively, and were higher than those of the control group (29.9 ng/mL and 17.7 pg/mL, respectively). The sensitivity, specificity, positive, and negative predictive values for resistin were 73.7%, 45.8%, 68.3%, and 52.4%, respectively., Conclusion: Resistin levels were higher in premature newborns with sepsis and correlated with IL-6 levels, which is an indicator of neonatal sepsis. This suggests that resistin may also be used in the diagnosis of neonatal sepsis. However, it has limited value when compared with the other inflammatory markers including C-reactive protein, procalcitonin, and IL-6., (Copyright © 2013. Published by Elsevier B.V.)

Vancomycin resistant enterococci (VRE) are important etiologic agents of nosocomial infections and colonization for hospitalized patients. Isolation rate of VRE is higher especially in neonatal intensive care units (NICUs), due to the immune insufficiency of neonates, frequent use of antibiotics and prolonged duration of hospitalization. The aims of this report were to present the rapid dissemination of VRE colonization in our NICU, to determine the factors related to colonization and to share the precautions taken to prevent the dissemination. Upon the isolation of VRE from the urine culture of a premature infant followed up in the NICU, rectal swab specimens were obtained from this index patient, other patients staying at the NICU, the related health-care personnel and also environmental sampling was performed. Although strict contact precautions were implemented for the VRE positive patient, VRE were isolated from the rectal swabs of other patients and the number of VRE positive cases increased to 11 on the 18th day. No VRE were detected in the environmental samples. By strict adherence and compliance to isolation precautions, physical separation of VRE positive newborns and healthcare workers and education of the personnel, VRE colonization was eradicated on the 55th day. During the period between the first detection of VRE colonization and the management of eradication (August 10th-October 4th 2009), 133 patients were followed up in the NICU and 52 (40%) of those patients were colonized by VRE. Patients were divided into two groups according to the presence or absence of VRE colonization. These patients' anthropometric and clinical findings were evaluated retrospectively. Gestational age and birth weights of VRE positive and negative patients were 30.9 ± 3.8 weeks and 1441 ± 543 g; 34.5 ± 4 weeks and 2396 ± 917 g, respectively (p< 0.05). VRE colonization was detected on the postnatal 16th day (days between 2-144). VRE became negative in 10 (19.2%) of the 52 colonized patients during follow-up in the hospital. None of the patients developed infection or sepsis due to VRE and no fatal case was detected. Mean durations of mechanical ventilation, hospitalization and antibiotic therapy were 15 (1-102) days, 34 (6-201) days and 23 (7-90) days, respectively in VRE positive patients, whereas those data were 3 (1-40) days, 9 (1-106) days and 10 (1-42) days in VRE negative patients. Antibiotic use (especially cephalosporins), days on mechanical ventilation and length of hospitalization were found significantly higher in VRE positive patients (p< 0.05) than those negatives, statistically. According to multiple variance analysis, the factor which independently affected VRE development was "duration of vancomycin use" [p= 0.04, OR = 0.67, CI (95%) = 0.45-0.98]. VRE colonization is seen more frequently in newborns who have medical problems during follow-up. Therefore surveillance cultures that performed routinely in NICUs, would be helpful to detect VRE colonization in time and to implement isolation precautions rapidly in order to prevent dissemination of the organism and decrease the incidence of bacteremia and death.

Background and Objective: To evaluate an intracuring method by changing the corneal curvature., Materials and Methods: An intrastromal tunnel was created by femtosecond laser in five cadaveric sheep eyes. Dental flowable restorative composite was used to fill the tunnel. A light-emitting diode light was applied for polymerization for 20 seconds. Flat plastic material was used for pressure on the cornea during polymerization. Keratometric measurements were obtained in all eyes using a rotating Scheimpflug camera., Results: Remarkable changes on the corneal curvature were observed after the intracuring method. Inferior or inferonasal flattening and opposite steepening was observed in all sheep eyes. The average flattening effect of this method was 10.6 diopters., Conclusion: This new application may be a promising technique for the treatment of keratoconus. The application of this technique in humans could offer improved treatment options in the future., (Copyright 2011, SLACK Incorporated.)

Among the potential risks of nasotracheal intubation are nasal bleeding, sinusitis, bacteremia, accidental turbinectomy, and some other structural damages. Retropharyngeal dissection is reported as a very rare complication of nasotracheal intubation, mostly encountered in elective surgery patients. A case with traumatic subcondylar fracture of the mandible is presented here, which is suspected to be the cause of the nasopharyngeal dissection that was observed during attempted nasotracheal intubation.

Background and Aim of the Study: Transthoracic two-dimensional echocardiography (TTE) is currently the 'gold standard' for the evaluation of rheumatic mitral valve disease. Multidetector computed tomography (MDCT) is a promising technique for the evaluation of heart valves. The study aim was to evaluate the planimetry of the mitral valve area (MVA) with 16-row MDCT in comparison with TTE, in patients with rheumatic mitral stenosis., Methods: Twenty-six patients (18 females, eight males; mean age 41.7 +/- 8.7 years) with rheumatic mitral valve disease, who had been referred for 16-row MDCT for various indications, such as evaluation of the coronary arteries, assessment of pulmonary vein anatomy before catheter ablation of paroxysmal atrial fibrillation, suspicion of aortic dissection or pulmonary embolism, were recruited. All patients were in sinus rhythm. The MDCT acquisition was performed using a 16-row scanner. Echocardiographic planimetry of MVA was performed in the standard parasternal short-axis view within one week., Results: Planimetry of the MVA with MDCT did not differ from that with TTE (1.88 +/- 0.46 cm2 versus 1.83 +/- 0.50 cm2, p = 0.242), and there was an excellent correlation between two techniques (r = 0.923, p < 0.0001). Seven patients had calcific mitral valves (mean calcium score 216.8 +/- 783.8 Agatston units). In these patients, MVA measured by MDCT was 1.73 +/- 0.39 cm2 and by TTE planimetry was 1.72 +/- 0.54 cm2 (p = 0.866; r = 0.963, p = 0.0005). When using the pressure half-time (PHT) method, the MVA was obtained in 24 of the 26 patients. MVA by PHT did not differ from the MVA calculated by TTE planimetry, nor from that obtained with MDCT planimetry (1.79 +/- 0.46 cm2 versus 1.81 +/- 0.51 cm2, p = 0.427 and 1.79 +/- 0.46 cm2 versus 1.86 +/- 0.48 cm2, p = 0.101, respectively). The correlation coefficient for the MDCT-derived MVA and PHT-derived MVA was 0.8969 (p < 0.0001). Although not statistically significant, in nine patients with moderate to severe mitral stenosis (MVA < 1.5 cm2), the MDCT tended to overestimate MVA compared to echo planimetry (1.35 +/- 0.19 cm2 versus 1.28 +/- 0.21 cm2, p = 0.059)., Conclusion: MDCT enabled accurate planimetry of the MVA in patients with rheumatic mitral stenosis, in comparison with TTE.

Objective: To measure blood and cerebrospinal fluid (CSF) uric acid (UA) levels of neonates with intraventricular hemorrhage (IVH), and to examine whether or not UA can be used to differentiate traumatic tap from IVH., Material and Methods: The control group (n = 19, group I) consisted of neonates presenting with signs requiring analysis of CSF but whose CSF indices proved to be normal. Traumatic taps (n = 15, group II) were mimicked by adding 2 drops of homologous blood to normal CSF samples. The IVH group (n = 21, group III) consisted of neonates who had been diagnosed by cranial ultrasonography or computed tomography scans. Data are presented as median (range)., Results: There was no significant difference between groups with respect to serum UA levels. While no significant difference was observed between CSF UA levels of the control [0.6 (0.1-1.8) mg/dl] and traumatic tap group [0.5 (0.3-1.1) mg/dl], the IVH group [1.6 (0.7-6.9) mg/dl] was found to have significantly higher CSF UA levels than groups I and II. Furthermore, although there were significant correlations between serum and CSF UA levels in the control and traumatic tap groups, no correlation was observed in the IVH group., Conclusion: CSF UA levels are increased in neonates with IVH and they may be used to differentiate a real hemorrhage from a traumatic tap., (Copyright (c) 2006 S.

The purpose of this study was to evaluate the influence of Hero 642 rotary Ni-Ti instruments driven at 300, 400, or 600 rpm on root canal straightening, loss of working length, and instrument breakage. Sixty mesial root canals from extracted human mandibular molars were divided into 3 groups of 20 each and were instrumented at the aforementioned rotational speeds with a crown-down technique. Using a digital intraoral radiography system directly on the images of pre- and postoperative radiographs, degrees of canal curvatures were measured and recorded. Statistical analysis showed that final canal curvatures and working lengths were significantly reduced compared with those of original values in each group (p < 0.001). However, using Hero 642 rotary Ni-Ti system at different rotational speeds had no effect on canal curvature and working length alterations (p > 0.05). No file breakage was observed in any of the groups.
