Abstract
BACKGROUND In countries where pertussis vaccination is not administered during pregnancy, the determination of pertussis antibody levels in pregnant women is very important in terms of knowing the current seroepidemiology and potential strategies for immunizations. METHODS We included 396 pregnant women who were admitted to 4 different obstetrics and gynecology clinics. Anti-Bordetella pertussis toxin (PT) IgG and anti-Bordetella pertussis filamentous hemagglutinin IgG levels in maternal and cord blood pairs were determined by the ELISA method. RESULTS Venous blood serum anti-PT level was below 5 IU/mL in 58.8%, 5-40 IU/mL in 34.8%, 40-100 IU/mL in 5.1% and >100 IU/mL in 1.3% of pregnant women. Cord blood serum anti-PT level was below 5 IU/mL in 47.7%, 5-40 IU/mL in 44.5%, 40-100 IU/mL in 6.8% and >100 IU/mL in 1% of pregnant women. In our study, the anti-PT level was found below 40 IU/mL in 93.6% of pregnant women and 92.2% of cord blood. Our study found the anti-filamentous hemagglutinin level below 40 IU/mL in 81% of pregnant women and 66.2% of cord blood. CONCLUSIONS Although it is known that pertussis causes serious morbidity and mortality in young infants all over the world and that the most effective and reliable way to prevent it is vaccination of pregnant women, it is a remarkable contradiction that pertussis vaccination rates and therefore seropositivity rates in pregnant women are very low.

Abstract
Functional gastrointestinal disorders (FGIDs) are characterized by a variety of symptoms that are frequently age-dependent, chronic, or recurrent and are not explained by structural or biochemical abnormalities. There are studies in the literature reporting different results regarding the relationship between prematurity and FGIDs. The main objective of this study was to compare the frequency of FGIDs between preterm and term infants. The secondary objective was to evaluate whether there was any association between neonatal characteristics and development of FGIDs. A multicenter prospective cohort study that included preterm infants born before 37 weeks of gestation and healthy term infants was carried out. At 1, 2, 4, 6, 9, and 12 months of age, infants were assessed for the presence of FGIDs using the Rome IV criteria. In preterm infants, an additional follow-up visit was made at 12 months corrected age. 134 preterm and 104 term infants were enrolled in the study. Infantile colic, rumination syndrome, functional constipation, and infant dyschezia were more common in preterm infants. Incidence of other FGIDs (infant regurgitation, functional diarrhea and cyclic vomiting syndrome) were similar among preterm and term infants. Preterm infants who are exclusively breastfeed in the first 6 months of life have a lower incidence of infantile colic (18.8% vs 52.1%, p = 0.025). In terms of chronological age, FGIDs symptoms started later in preterm infants; this difference was statistically significant for infantile colic and regurgitation (median age 2 months vs 1 month, p < 0.001). Conclusions: Preterm infants have a higher prevalence of FGIDs compared with term controls. Therefore, especially if they have gastrointestinal complaints, they should be screened for FGIDs. Possibly due to maturational differences, the time of occurrence of FGIDs may differ in preterm infants. Infantile colic incidence decreases with exclusive breastfeeding. What is Known: • The functional gastrointestinal disorders are a very common in infancy. • Data on preterm infants with FGIDs are currently very limited. What is New: • Preterm infants have a higher incidence of infantile colic, rumination syndrome, functional constipation and infant dyschezia when compared to term infants. • Preterm infants who are exclusively breastfed during the first 6 months of life experience a lower incidence of infantile colic.

Abstract
INTRODUCTION Due to the rapid advancement of technology, there has been a noteworthy increase in the diversity and abundance of activities involving children. The most effective methods to enhance and facilitate children's media interactions are to minimize, reduce, use with caution, and establish healthy patterns. We aimed to evaluate media exposure of children below five years of age. MATERIAL AND METHODS This is a prospective, observational, cross-sectional study that was conducted between December 2017 and September 2019 in Eskişehir, Türkiye. To assess the frequency of electronic device usage among children under the age of five, including televisions, laptops, tablets, and mobile phones, as well as its impact on their sleep patterns and physical measurements, and to evaluate families' understanding of the terms "screen time" and "back screen time," we developed a questionnaire. RESULTS We analyzed a total of 731 questionnaires: 334 (45.7%) were girls, 397 (54.3%) were boys, and the mean age was 33.55±16.37 months. Upon examining the technical equipment accessible to the children in our study, we found that 98.6% possessed a television, 96.9% owned a mobile phone, 54% had a laptop, 49.5% had a tablet, and 34.1% possessed a gaming console. The study revealed the following proportions of electronic devices in children's rooms: 13% televisions, 11.9% tablets, 7.4% laptops, and 7% mobile phones. There has been a substantial increase in the amount of time they spend watching television and playing computer games among children who have at least one sibling. There was a statistically significant disparity between the television viewing periods and the body mass index of children older than two years old. Additionally, we have seen a significant disparity in the presence of media devices in children's bedrooms and the subsequent impact on their sleep duration and patterns throughout both nighttime and daytime. Around 65.8% of parents did not know of the concept of screen time, while 88.4% of parents did not know of the concept of back screen time. DISCUSSION Parental compliance with the current guidelines for screen time is insufficient, among parents with children under the age of five, even though exposure to screens begins in the first months of life. Our analysis highlighted the necessity for parents to establish and enforce a unified and logical media usage policy for all children residing in the household. It is crucial to allocate sufficient time during the routine healthcare visit to discuss these recommendations.

Abstract
OBJECTIVES Septic arthritis (SA) is a serious bacterial infection that must be treated efficiently and timely. The large number of culture-negative cases makes local epidemiological data important. Accordingly, this study aimed to evaluate the etiology, clinical characteristics, and therapeutic approach of SA in children in Turkiye, emphasizing the role of real-time polymerase chain reaction (PCR) techniques in the diagnosis. METHODS In this multi-center, prospective study, children hospitalized due to SA between February 2018 and July 2020 in 23 hospitals in 14 cities in Turkiye were included. Clinical, demographic, laboratory, and radiological findings were assessed, and real-time PCR was performed using synovial fluid samples. RESULTS Seventy-five children aged between 3 and 204 months diagnosed with acute SA were enrolled. Joint pain was the main complaint at admission, and the most commonly involved joints were the knees in 58 patients (77.4%). The combination of synovial fluid culture and real-time PCR detected causative bacteria in 33 patients (44%). In 14 (18.7%) patients, the etiological agent was demonstrated using only PCR. The most commonly isolated etiologic agent was Staphylococcus aureus, which was detected in 22 (29.3%) patients, while Streptococcus pyogenes was found in 4 (5.3%) patients and Kingella kingae in 3 (4%) patients. Streptococcus pyogenes and Kingella kingae were detected using only PCR. Most patients (81.3%) received combination therapy with multiple agents, and the most commonly used combination was glycopeptides plus third-generation cephalosporin. CONCLUSIONS Staphylococcus aureus is the main pathogen in pediatric SA, and with the use of advanced diagnostic approaches, such as real-time PCR, the chance of diagnosis increases, especially in cases due to Kingella kingae and Streptococcus pyogenes.

Abstract
The composition of the human milk (HM) microbiota and, consequently, the microorganisms that are passed on to the infant through breastfeeding, can be influenced by various factors such as the mother's health and diet, gestational age, delivery mode, lactation stage, method of infant feeding, and geographical location. The aim of the Human Milk-Gest Study was to compare the microbiota of transient (postpartum 7-15 days) and mature HM (postpartum 45-90 days) of 44 mothers, and to investigate any potential changes associated with preterm birth, mode of delivery, and birth weight in relation to gestational age. The data were classified into five study groups: normal spontaneous delivery-term (NS-T) newborns, cesarean delivery-term (CS-T) newborns, preterm (PT) newborns (with a gestational age of less than 37 weeks), small for gestational age (SGA) newborns, and large for gestational age (LGA) newborns. An analysis of differential abundance was conducted using ANCOM-BC to compare the microbial genera between transient and mature HM samples as well as between other study groups. A significant difference was detected between HM samples at different sampling times and between the study groups (p < 0.01). In transient HM samples, Ralstonia, Burkholderiaceae_uc, and Pelomonas were significantly dominant in the LGA group compared to the NS-T, CS-T, PT, and SGA groups. In mature HM samples, Burkholderiaceae_uc, Ralstonia, Pelomonas, and Klebsiella were significantly dominant in the LGA group compared to the NS-T, CS-T, and PT groups, while Ralstonia, Burkholderiaceae_uc, and Pelomonas were significantly dominant in the LGA group compared to the SGA group. Differences were also detected between the transient and mature HM samples in the CS-T, PT, SGA, and LGA groups, but no differences occurred in the NS-T groups. In conclusion, we showed that Ralstonia, Burkholderiaceae_uc, and Pelomonas were significantly dominant in the LGA group in transient HM and continued in mature HM. The body mass index (BMI) of the mothers in the LGA group was not >30 at conception, however, the maternal BMI at birth and maternal weight gain during pregnancy were higher than in the other groups. The nutritional composition of HM is specifically designed to meet infant nutritional requirements during early life. Evaluating the effects of HM microbiota on infant microbiota composition and short- and long-term health effects in larger studies would be useful.

Abstract
INTRODUCTION Gut microbiota manipulation may be a potential therapeutic target to reduce host energy storage. There is limited information about the effects of probiotics/synbiotics on intestinal microbiota composition in children and adolescents with obesity. The objective of this randomized double-blind placebo-controlled trial was to test the effects of a multispecies synbiotic on intestinal microbiota composition in children and adolescents with exogenous obesity. METHOD Children with exogenous obesity were managed with a standard diet and increased physical activity and were randomly allocated into two groups at a ratio of 1:1; the 1st group received synbiotic supplementation (probiotic mixture including Lactobacillus acidophilus, Lacticaseibacillus. rhamnosus, Bifidobacterium bifidum, Bifidobacterium longum, Enterococcus faecium (total 2.5 × 109 CFU/sachet) and fructo-oligosaccharides (FOS; 625 mg/sachet) for 12 weeks; the 2nd group received placebo once daily for 12 weeks. Fecal samples were obtained before and at the end of the 12-week intervention to characterize the changes in the gut microbiota composition. Detailed metagenomic and bioinformatics analyses were performed. RESULTS Before the intervention, there were no significant differences in alpha diversity indicators between the synbiotic and placebo groups. After 12 weeks of intervention, the observed taxonomic units and Chao 1 were lower in the synbiotic group than at baseline (p < 0.001 for both). No difference for alpha diversity indicators was observed in the placebo group between baseline and 12 weeks of intervention. At the phylum level, the intestinal microbiota composition of the study groups was similar at baseline. The major phyla in the synbiotic group were Firmicutes (66.7%) and Bacteroidetes (18.8%). In the synbiotic group, the Bacteroidetes phylum was higher after 12 weeks than at baseline (24.0% vs. 18.8%, p < 0.01). In the synbiotic group, the Firmicutes/Bacteroidetes ratio was 3.54 at baseline and 2.75 at 12 weeks of intervention (p < 0.05). In the placebo group, the Firmicutes/Bacteroidetes ratio was 4.70 at baseline and 3.54 at 12 weeks of intervention (p < 0.05). After 12 weeks of intervention, the Firmicutes/Bacteroidetes ratio was also lower in the synbiotic group than in the placebo group (p < 0.05). In the synbiotic group, compared with the baseline, we observed a statistically significant increase in the genera Prevotella (5.28-14.4%, p < 0.001) and Dialister (9.68-13.4%; p < 0.05). Compared to baseline, we observed a statistically significant increase in the genera Prevotella (6.4-12.4%, p < 0.01) and Oscillospira (4.95% vs. 5.70%, p < 0.001) in the placebo group. In the synbiotic group, at the end of the intervention, an increase in Prevotella, Coprococcus, Lachnospiraceae (at the genus level) and Prevotella copri, Coprococcus eutactus, Ruminococcus spp. at the species level compared to baseline (predominance of Eubacterium dolichum, Lactobacillus ruminis, Clostridium ramosum, Bulleidia moorei) was observed. At the end of the 12th week of the study, when the synbiotic and placebo groups were compared, Bacteroides eggerthi species were dominant in the placebo group, while Collinsella stercoris species were dominant in the synbiotic group. CONCLUSION This study is the first pediatric obesity study to show that a synbiotic treatment is associated with both changes intestinal microbiota composition and decreases in BMI. Trial identifier: NCT05162209 (www. CLINICALTRIALS gov).

Abstract
Type 2 diabetes mellitus is a chronic health problem that can be controlled by slowing one's carbohydrate metabolism by inhibiting α-glucosidase, an enzyme responsible for carbohydrate degradation. Currently, drugs for type 2 diabetes have limitations in terms of safety, efficiency, and potency, while cases are rapidly increasing. For this reason, the study planned and moved towards drug repurposing by utilizing food and drug administration (FDA)-approved drugs against α-glucosidase, and investigated the molecular mechanisms. The target protein was refined and optimized by introducing missing residues, and minimized to remove clashes to find the potential inhibitor against α-glucosidase. The most active compounds were selected after the docking study to generate a pharmacophore query for the virtual screening of FDA-approved drug molecules based on shape similarity. The analysis was performed using Autodock Vina (ADV)-based on binding affinities (-8.8 kcal/mol and -8.6 kcal/mol) and root-mean-square-deviation (RMSD) values (0.4 Å and 0.6 Å). Two of the most potent lead compounds were selected for a molecular dynamics (MD) simulation to determine the stability and specific interactions between receptor and ligand. The docking score, RMSD values, pharmacophore studies, and MD simulations revealed that two compounds, namely Trabectedin (ZINC000150338708) and Demeclocycline (ZINC000100036924), are potential inhibitors for α-glucosidase compared to standard inhibitors. These predictions showed that the FDA-approved molecules Trabectedin and Demeclocycline are potential suitable candidates for repurposing against type 2 diabetes. The in vitro studies showed that trabectedin was significantly effective with an IC50 of 1.263 ± 0.7 μM. Further investigation in the laboratory is needed to justify the safety of the drug to be used in vivo.

Abstract
Human milk oligosaccharides (HMOs) are the third most important solid component in human milk and act in tandem with other bioactive components. Individual HMO levels and distribution vary greatly between mothers by multiple variables, such as secretor status, race, geographic region, environmental conditions, season, maternal diet, and weight, gestational age and mode of delivery. HMOs improve the gastrointestinal barrier and also promote a bifidobacterium-rich gut microbiome, which protects against infection, strengthens the epithelial barrier, and creates immunomodulatory metabolites. HMOs fulfil a variety of physiologic functions including potential support to the immune system, brain development, and cognitive function. Supplementing infant formula with HMOs is safe and promotes a healthy development of the infant revealing benefits for microbiota composition and infection prevention. Because of limited data comparing the effect of non-human oligosaccharides to HMOs, it is not known if HMOs offer an additional clinical benefit over non-human oligosaccharides. Better knowledge of the factors influencing HMO composition and their functions will help to understand their short- and long-term benefits.

Abstract
Studies describing paediatric sleep patterns are needed by taking culture into consideration. The aim of this study was to identify parent-reported sleep-wake patterns in young children and explore possible factors influencing sleep problems. The mothers of 2,434 young children enrolled from well-child outpatient clinics in Turkey completed an online survey including sociodemographic variables, Brief Infant Sleep Questionnaire, Edinburgh Postnatal Depression Scale and Generalised Anxiety Disorder scales. Overall, young children in Turkey go to bed late (10:00 p.m.), awaken twice per night for 30 min, and obtain 11.5 h of total sleep, showing no sex-specific differences. Distinct night-time sleep patterns emerged after 18 months of age. Importantly, although currently breastfed healthy children were 3.8-times less likely to sleep through the night, total sleep duration and exclusive breastfeeding duration were higher in children who were not sleeping through the night. Overall, bedsharing was identified in 11.5%, and only room sharing was reported in 52.9%. Parental perception of a child's sleep as problematic was 35.8%. Mothers with higher educational attainment were more likely to perceive their children's sleep as a problem. Maternal depressive and anxious symptoms and a history of excessive infant crying were the determinants predicting the likelihood of both parent-perceived sleep problems and poor sleepers. The present analysis of sleep structure in infancy and toddlerhood provides reference data for well-child visits. These findings highlight the importance of considering maternal anxiety, depression and behaviour management techniques to cope with fussy infants in addressing childhood behavioural sleep problems.

Abstract
Studies on the effects of synbiotics on obesity in children are limited. The objective of this randomized double-blind placebo-controlled trial was to test the effects of a multispecies synbiotic during 12 weeks on anthropometric measurements, glucose metabolism and lipid parameters in 61 children with exogenous obesity. All children were treated with a standard diet and increased physical activity and received once daily a synbiotic supplement (probiotic mixture including Lactobacillus acidophilus, Lacticaseibacillus rhamnosus, Bifidobacterium bifidum, Bifidobacterium longum, Enterococcus faecium and fructo-oligosaccharides) or daily placebo for 12 weeks. At baseline, no statistically significant differences existed in anthropometric measurements, glucose and lipid parameters between both groups. We observed changes for anthropometric measures (% reduction comparing to baseline) in both synbiotic and placebo groups. After 12 weeks; changes (% reduction comparing to baseline) in weight (p < 0.01), BMI (p < 0.05), waist circumference (p < 0.05) and waist circumference to height ratio (p < 0.05) were significantly higher in the children receiving the synbiotic supplement. There is no difference in glucose metabolism, lipid parameters, presence of non-alcoholic fatty liver disease between both groups after 12 weeks. The daily intake of a multispecies synbiotic in addition to diet and increased physical activity did improve anthropometric measurements: body weight, BMI, waist circumference and waist/height ratio. The supplementation of this synbiotic is an efficient weight-loss strategy above diet and exercise in pediatric obesity (Trial identifier: NCT05162209).

Abstract
UNLABELLED Microbiota composition may play a role in the development, prognosis, or post-infection of COVID-19. There are studies evaluating the microbiota composition at the time of diagnosis and during the course of COVID-19, especially in adults, while studies in children are limited and no study available in children with multisystem inflammatory syndrome in children (MIS-C). This study was planned to compare intestinal microbiota composition in children diagnosed with MIS-C and acute COVID-19 infection with healthy children. In this prospective multicenter study, 25 children diagnosed with MIS-C, 20 with COVID-19 infection, and 19 healthy children were included. Intestinal microbiota composition was evaluated by 16 s rRNA gene sequencing. We observed changes of diversity, richness, and composition of intestinal microbiota in MIS-C cases compared to COVID-19 cases and in the healthy controls. The Shannon index was higher in the MIS-C group than the healthy controls (p < 0.01). At phylum level, in the MIS-C group, a significantly higher relative abundance of Bacteroidetes and lower abundance of Firmicutes was found compared to the control group. Intestinal microbiota composition changed in MIS-C cases compared to COVID-19 and healthy controls, and Faecalibacterium prausnitzii decreased; Bacteroides uniformis, Bacteroides plebeius, Clostridium ramosum, Eubacterium dolichum, Eggerthella lenta, Bacillus thermoamylovorans, Prevotella tannerae, and Bacteroides coprophilus were dominant in children with MIS-C. At species level, we observed decreased Faecalibacterium prausnitzii, and increased Eubacterium dolichum, Eggerthella lenta, and Bacillus thermoamylovorans in children with MIS-C and increased Bifidobacterium adolescentis and Dorea formicigenerasus in the COVID-19 group. Our study is the first to evaluate the microbiota composition in MIS-C cases. There is a substantial change in the composition of the gut microbiota: (1) reduction of F. prausnitzii in children with MIS-C and COVID-19; (2) an increase of Eggerthella lenta which is related with autoimmunity; and (3) the predominance of E. dolichum is associated with metabolic dysfunctions and obesity in children with MIS-C. CONCLUSIONS Alterations of the intestinal microbiota might be part of pathogenesis of predisposing factor for MIS-C. It would be beneficial to conduct more extensive studies on the cause-effect relationship of these changes in microbiota composition and their effects on long-term prognosis. WHAT IS KNOWN • Microbiota composition may play a role in the development, prognosis, or post-infection of COVID-19. • However, the number of studies on children is limited, and no study on multisystem inflammatory syndrome in children is currently available (MIS-C). WHAT IS NEW • In individuals with MIS-C, the composition of the gut microbiota changed dramatically. • Decreased Faecalibacterium prausnitzii have been observed, increased Eggerthella lenta, which was previously linked to autoimmunity, and predominance of Eubacterium dolichum which was linked to metabolic dysfunction and obesity.

Abstract
Meningococcal carriage studies and transmission modeling can predict IMD epidemiology and used to define invasive meningococcal disease (IMD) control strategies. In this multicenter study, we aimed to evaluate the prevalence of nasopharyngeal Neisseria meningitidis (Nm) carriage, serogroup distribution, and related risk factors in Turkey. Nasopharyngeal samples were collected from a total of 1267 children and adolescents and were tested with rt-PCR. Nm carriage was detected in 96 participants (7.5%, 95% CI 6.1–9.0), with the peak age at 13 years (12.5%). Regarding age groups, Nm carriage rate was 7% in the 0–5 age group, was 6.9%in the 6–10 age group, was 7.9% in the 11–14 age group, and was 9.3% in the 15–18 age group. There was no statistically significant difference between the groups (p > 0.05). The serogroup distribution was as follows: 25% MenX, 9.4% MenA, 9.4% MenB, 2.1% MenC, 3.1% MenW, 2.1% for MenY, and 48.9% for non-groupable. The Nm carriage rate was higher in children with previous upper respiratory tract infections and with a high number of household members, whereas it was lower in children with antibiotic use in the last month (p < 0.05 for all). In this study, MenX is the predominant carriage strain. The geographical distribution of Nm strains varies, but serogroup distribution in the same country might change in a matter of years. Adequate surveillance and/or a proper carriage study is paramount for accurate/dynamic serogroup distribution and the impact of the proposed vaccination.

Abstract
The human milk (HM) microbiota is a significant source of microbes that colonize the infant gut early in life. The aim of this study was to compare transient and mature HM virome compositions, and also possible changes related to the mode of delivery, gestational age, and weight for gestational age. Overall, in the 81 samples analyzed in this study, reads matching bacteriophages accounted for 79.5% (mainly Podoviridae, Myoviridae, and Siphoviridae) of the reads, far more abundant than those classified as eukaryotic viruses (20.5%, mainly Herpesviridae). In the whole study group of transient human milk, the most abundant families were Podoviridae and Myoviridae. In mature human milk, Podoviridae decreased, and Siphoviridae became the most abundant family. Bacteriophages were predominant in transient HM samples (98.4% in the normal spontaneous vaginal delivery group, 92.1% in the premature group, 89.9% in the C-section group, and 68.3% in the large for gestational age group), except in the small for gestational age group (only ~45% bacteriophages in transient HM samples). Bacteriophages were also predominant in mature HM; however, they were lower in mature HM than in transient HM (71.7% in the normal spontaneous vaginal delivery group, 60.8% in the C-section group, 56% in the premature group, and 80.6% in the large for gestational age group). Bacteriophages still represented 45% of mature HM in the small for gestational age group. In the transient HM of the normal spontaneous vaginal delivery group, the most abundant family was Podoviridae; however, in mature HM, Podoviridae became less prominent than Siphoviridae. Myoviridae was predominant in both transient and mature HM in the premature group (all C-section), and Podoviridae was predominant in transient HM, while Siphoviridae and Herpesviridae were predominant in mature HM. In the small for gestational age group, the most abundant taxa in transient HM were the family Herpesviridae and a species of the genus Roseolovirus. Bacteriophages constituted the major component of the HM virome, and we showed changes regarding the lactation period, preterm birth, delivery mode, and birth weight. Early in life, the HM virome may influence the composition of an infant's gut microbiome, which could have short- and long-term health implications. Further longitudinal mother-newborn pair studies are required to understand the effects of these variations on the composition of the HM and the infant gut virome.

Abstract
Background Febrile seizure is the most common neurological disorder in childhood. The exact pathophysiology of febrile seizures is unknown. Recent studies showed the role of vitamin K in nonhematological and inflammatory disorders. This study aimed to investigate the serum vitamin K levels in children with febrile seizures. Aims To evaluate vitamin K levels in children with febrile seizures. Study Design Prospective case-control study. Methods This multicenter study examined representative populations in 8 different cities in Turkey between April 1, 2018 and April 1, 2019. Blood samples were taken from all children at presentation. Vitamin K1, vitamin K2, tumor necrosis factor-alpha, interleukin 1 beta, and interleukin 6 levels were determined by enzyme-linked immunosorbent assay. Results A total of 155 children were included in the study—84 children with febrile seizures and 71 children in febrile control group. Serum vitamin K1 and vitamin K2 levels were also higher in children with febrile seizures than in the controls. The results of statistical analysis showed that vitamin K1 and vitamin K2 levels were correlated with tumor necrosis factor-alpha, interleukin 1 beta, and interleukin 6 levels. The median vitamin K1 and vitamin K2 levels of children experiencing their first febrile seizure were higher than those in children with recurrent febrile seizures. Type of febrile seizure has no effect on serum vitamin K1 and vitamin K2 levels. Conclusion In children with febrile seizures, vitamin K levels are higher than those in the control group. These new findings may contribute to elucidating the etiopathogenesis of febrile seizures.

Abstract
Intensive chemotherapy can cause long-lasting immunosuppression in children who survived cancer. The immunosuppression varies according to the type of cancer, intensity of chemotherapy and age of the patient. A sufficient immune reconstruction when has been completed in childhood cancer survivors, the re-vaccination program can achieve sufficient antibody levels for some of the life-threatening vaccine-preventable infectious diseases. This study evaluates the serological status of pediatric acute lymphoblastic leukemia (ALL) cases before and after the intensive chemotherapy treatment. Antibodies against measles, mumps, rubella, varicella, hepatitis A and B were tested with the enzyme-linked immunosorbent assay (ELISA) method. Antibody titers were measured firstly at the leukemia diagnosis time when the chemotherapy was not started. The second evaluation of antibody titers was studied at 6 months after the cessation of chemotherapy for all patients. Forty-six patients with the mean age of 6.1 ± 4.5 years were participated in this study. Changing to seronegative after treatment was significantly different in measles, rubella, hepatitis A and hepatitis B (p < .05). Seventy-eight (28%) antibody levels in the patients were non-protective for all diseases. Only three (7%) patients had protective antibody levels for all diseases in the sixth month of chemotherapy cessation. There was a negative correlation between patient's age and losing protective antibody levels for any vaccine-preventable disease (p < .05). Antibody levels against vaccine-preventable diseases have evident that reduced after ALL treatment at childhood. Pediatric ALL survivors must be re-vaccinated for vaccine-preventable diseases after achieving immune reconstruction.

Abstract
Intestinal and human milk microbiota studies during infancy have shown variations according to geographical location, delivery mode, gestational age, and mother-related factors during pregnancy. In this study, we performed metagenomic mycobiota analyses of 44 transient and mature human milk among five different groups: mothers of normal spontaneous delivery-term (NS-T), caesarean delivery-term (CS-T), premature (PT), small for gestational age (SGA), and large for gestational age (LGA) infants. Fungi were detected in 80 out of the 88 samples. Regarding the number of observed fungal species, the NS-T group was more homogeneous (less variable) comparing the other groups (P<0.05). In the transient human milk samples, the most abundant species were Saccharomyces cerevisiae (33.3%) and Aspergillus glaucus (27.4%). While A. glaucus (33.7%) was second most abundant species in mature milk, S. cerevisiae disappeared (P<0.01) and Penicillium rubens became the most abundant species (35.5%) (P<0.05). Among the NS-T group, the most abundant species was Malassezia globosa in both transient and mature milk. In contrast, S. cerevisiae was the most abundant species in transient human milk (45.0%) in the CS-T group, but it disappeared in mature milk (P<0.01). In transient milk, M. globosa was only represented 6.0-9.0% of taxa in the PT, SGA, and LGA groups (P<0.05). In transient and mature milk in the PT, SGA and LGA groups, the most abundant species were A. glaucus and P. rubens. In mature milk samples, P. rubens is more abundant in CS-T group, PT group and LGA group, than the NS-T groups (P<0.05 for all). Although fungi constitute only a very small part of the human milk microbiome, we observed some changes that the human milk mycobiota composition varies in caesarean delivery, premature, SGA and LGA groups, comparing the normal spontaneous delivery, as well as differences between transient and mature human milk.

Abstract
OBJECTIVE It is important to identify undesirable toxins and metabolites present in human milk that may be passed on to nursing infants. Such residues may derive from the antibiotics that are widely used to treat infectious diseases in both humans and food-producing animals. To the best of our knowledge, there are no reports in the literature on human milk antibiotic residue levels. PATIENT AND METHODS As a part of the Human Milk Artificial Pollutants (HUMAP) study, we aimed to evaluate human milk antibiotic residues among mothers with 7 to 90-day-old babies. Pregnant women who had received antibiotic treatment during pregnancy were excluded. The use of antibiotic prophylaxis with cefazoline sodium during labor was noted among the study subjects. Human milk antibiotic residues were evaluated with the InfiniPlex for Milk Array (Randox Laboratories, London, United Kingdom), a semi-automated system with a multi-array biochip designed to detect antibiotic residues and toxins. RESULTS The HUMAP study included 83 mothers, ranging in age from 17 to 41 years (mean 29.7 ± 6.2 years). Of these, 59% received cefazoline sodium shortly after birth, while 41% did not receive any antibiotics during the pregnancy, delivery or lactational periods. Testing revealed that 71/83 (85.5%) human milk samples were positive for beta-lactams and 12 (14.5%) samples were positive for quinolones. There was no difference in maternal age, gestational week, delivery type, sampling time, maternal dietary habits between the mothers with quinolones or beta-lactam residues in their milk and those without (p > 0.05 for both). Beta-lactam and quinolone residues were detected in 85.7% and 23.5%, respectively, of the human milk samples of mothers who did not receive antibiotics at birth and/or during the first seven days after birth. CONCLUSIONS We found that the majority of human milk samples included beta-lactams or quinolones, even though the mothers did not receive these antibiotics during pregnancy and lactation. Antibiotic residues in human milk may affect early maintenance of the intestinal microbiota. Previous studies have shown that antimicrobials in food might increase the risks of allergies and could lead to the development of antibiotic-resistant bacterial strains. Effective policies on food safety and appropriate antibiotic use during pregnancy and lactation are needed.

Abstract
Streptococcus pneumoniae is a major cause of bacterial meningitis in children. It can progress and carries a serious risk of mortality and morbidity despite effective treatment. Cochlear implantation is a fairly successful procedure for restoring hearing in cases of sensorineural hearing loss. Moreover, patients with cochlear implants are at increased risk of contracting pneumococcal meningitis compared to the general population. The development of meningitis is associated with pathogens in the middle ear that contaminate the cerebrospinal fluid (CSF), as a result of congenital anomalies in the cochlea, and the cochlear implant. A 4-year-old girl presented to our clinic with fever, vomiting, and weakness. A physical examination showed an axillary temperature of 38.3°C, heart rate of 134/min, respiration rate of 50 breaths/minute, and arterial blood pressure of 120/88 mmHg. The patient also had a neck stiffness and her Kernig and Brudzinski signs were positive. It was discovered that the patient had undergone cochlear implantation approximately five months prior due to bilateral congenital sensorineural hearing loss. She had also received the Haemophilus influenzae type b and PCV-13 vaccines in line with the national immunization calendar. Her laboratory findings showed a leukocyte count of 21.900/mm3 (neutrophils 90% and lymphocytes 10%) and her procalcitonin level was 1.22 ng/ml. An uncountable number of neutrophils was identified in her cerebrospinal fluid, which led to the initial diagnosis of meningitis. There was also 1 mg/dl of glucose (blood glucose, 102 mg/dl) and 706 mg/dl of protein in her cerebrospinal fluid. Empirically, vancomycin (60 mg/kg/day) and ceftriaxone (100 mg/kg/day) were started. Following 5 days of antibiotic treatment, penicillin-susceptible S.pneumoniae was yielded in her CSF culture and identified as serotype 24B. S.pneumoniae with the same antibiotic sensitivity was also identified in her blood culture. Since rhinorrhea was observed on day 16 of hospitalization, she underwent an operation to repair the fistula tract. A computerized tomography cranial scan was performed after the development of acute mental fog at postoperative day 3 and showed brain edema and a thrombus in the right middle cerebral artery. The patient died on day 42 of hospitalization due to multiple organ failure. To our knowledge, this is the first case of meningitis reported in our country associated with S.pneumoniae serotype 24B in a patient with a cochlear implant. While there has been a decrease in the prevalence of invasive pneumococcal disease with routine administration of the pneumococcal conjugate vaccine, a relative increase has been observed in its non-vaccine serotypes. This is relevant not only to patients with more risk factors, such as a cochlear implant, but also those who are at lower risk for pneumococcal infection.

Abstract
Background: Chronic disease of children can cause changes in the health-related quality of life (HrQoL) of the family members. Aims: To evaluate the HrQoL of healthy siblings of children with chronic disease. Study Design: Cross-sectional study. Methods: The study included healthy sibling of children with chronic disease (cerebral palsy, epilepsy, diabetes, celiac disease, hematologic/oncologic disease, or asthma) and healthy sibling of healthy children to evaluate the quality of life. We used the Pediatric Quality of Life Inventory questionnaire; the physical health and psychosocial health scores were calculated using the responses of the sibling and parent. The primary endpoint was the comparison of HrQoL scores of healthy siblings of children with chronic disease and that of healthy siblings of healthy children. Results: This study included a respective healthy sibling of 191 children with chronic disease and healthy sibling of 100 healthy children. The physical health, psychosocial health, and total health scores of healthy siblings of children with chronic disease were significantly lower than that of healthy siblings of healthy children (p<0.001). Among the healthy siblings of children with chronic disease, the lowest psychosocial health score was found in the siblings of children with cerebral palsy, hematologic/oncologic disease, and asthma (p<0.001). The global impact on the quality of life for healthy siblings of children with chronic disease was significantly higher in the self-report of the children than that of the parents (30.4% versus 15.1%, p<0.05). Conclusion: Most healthy siblings of children with chronic disease are physically and psychosocially affected and there is low parental awareness of this condition. This can increase the risk of emotional neglect and abuse of these children. Therefore, special support programs are needed for the families of children with chronic diseases.

Abstract
The quality of life determination of children with chronic disease is closely related to treatment success. Quality of life assessment studies revealed that it was not limited to the individual, the quality of life of the family members also had to be assessed. Along with the child being diagnosed with chronic illness, some changes occur in the family structure, and in family roles. Quality of life assessment studies in healthy siblings generally indicate a global influence. These children live in different senses such as closure, aggression, depression, anxiety, guilt, and isolation. Psychosocial impact (short or long-term) of healthy siblings have been associated with disease type, severity, disease duration, age, sex, and ability to cope. Further comprehensive studies among healthy siblings of children with chronic disease about quality of life are needed. Building support groups (especially family support groups) to express feelings and thoughts freely for healthy siblings can positively affect the well-being and self-esteem of the child.

Abstract
BACKGROUND Febrile seizure is the most common childhood neurological disorder, is an important health problem with potential short- and long-term complications, also leading to economic burden and increased parental anxiety about fevers and seizures occurring in their children. There are no routine recommendation to detect etiological causes of FS for neurological perspective, further knowledge about the etiological causes of FS in children will support preventive measures and follow-up strategies. The aim of this study is to evaluate the percentage of respiratory viruses in children with FS. METHODS This prospective multicenter study, entitled "Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study)" examined representative populations in eight different cities in Turkey between March 1, 2016 and April 1, 2017. Nasopharyngeal swabs were taken from all children at presentation. A respiratory multiplex array was performed to detect for influenza A and B; respiratory syncytial virus A and B; human parainfluenza virus 1-2-3 and 4; human coronavirus 229E and OC43; human rhinovirus; human enterovirus; human adenovirus; human bocavirus; human metapneumovirus. RESULTS During the study period, at least one virus was detected in 82.7% (144/174) of children with FS. The most frequently detected virus was adenovirus, followed by influenza A and influenza B. Detection of more than one virus was present in 58.3% of the children with FS, and the most common co-existence was the presence of adenovirus and influenza B. In children younger than 12 months, Coronavirus OC43 was the most common, while influenza A was most frequently observed in children older than 48 months (p < 0.05). Human bocavirus was common in children who experienced complex FS, while respiratory syncytial virus (RSV) A was more common in children who experienced simple FS. Influenza B virus was the most common virus identified in children who were experiencing their first incidence of FS (p < 0.05). CONCLUSIONS This study indicates that respiratory viruses are important in the etiology of FS in children. The results show that antibiotics must be prescribed carefully in children with FS since the majority of cases are related to viral causes. Widespread use of the existing quadrivalent influenza vaccine might be useful for the prevention of FS related to the flu. Further vaccine candidates for potential respiratory pathogens, including RSV, might be helpful for the prevention of FS.

Abstract
INTRODUCTION Zearalenone (ZEA) and deoxynivalenol (DON) are toxic fungal secondary metabolites, found mainly in contaminated food, that are associated with serious health problems. It is important to identify undesirable toxins and metabolites that may be present in human milk. The aim of this study was to evaluate human milk ZEA and DON levels, total daily intake of ZEA and DON; and their possible relationship with maternal dietary habits. METHODS We enrolled 90 lactating mothers who had 7- to 90-day-old babies. A dietary questionnaire was completed by each of the mothers. Human milk samples were obtained from 90 mothers, and human milk ZEA and DON levels were evaluated with the solid-phase direct enzyme immunoassay. The total daily intake (TDI) was calculated for the 63 exclusively breastfed infants. RESULTS ZEA was detected in all human milk samples; median was 173.8 ng/L (35.7-682 ng/L). The calculated median TDI for ZEA was 33.0 ng/kg body weight (bw) (10.4-120.5 ng/kg) among exclusively breast-fed infants, none of them had a TDI that was above the previously defined threshold levels. Human milk ZEA levels were associated with the maternal consumption of meat, fish, dry fig, dried apricot, flaked red spice and spice. The median DON levels was 3924 ng/L (400-14997 ng/L). The median TDI of DON was 750 ng/kg (240-2774 ng/kg) among exclusively breastfed infants and 36% out of them, the TDI for DON was above the previously defined threshold level. Human milk DON levels were associated with the maternal meat consumption. CONCLUSIONS Our findings are indicative of dietary exposure to mycotoxins during the pregnancy and lactation periods in nursing mothers. Further, the excessive TDI values for DON observed in 36% of the exclusively breastfed infants point to the need for further regulations and recommendations on the dietary habits of pregnant/nursing mothers in order to avoid exposure to potential mycotoxins.

Abstract
INTRODUCTION Bacterial meningitis is one of the leading causes of morbidity and mortality among children and adults. Better understanding of the seroepidemiology of meningitis is critical for both the selection and implementation of an effective meningitis vaccine for the national immunization program. Because physicians play a crucial role in the implementation of this vaccine, the aim of this study was to evaluate the attitudes, behaviors, and knowledge of healthcare professionals in Turkey regarding the diagnosis, treatment and prevention of bacterial meningitis, especially pneumococcal and meningococcal meningitis. METHODS This study used a cross-sectional electronic survey with a national convenience sample of 339 physicians (171 pediatric age specialists [PAS] and 168 adult patient specialists [APS]) in Turkey. A web-based questionnaire which consisted 28 questions about the definition, diagnosis, and treatment of bacterial as well as knowledge and/or attitudes about meningococcal vaccines, was designed. RESULTS Approximately 72.9% (n = 247) of the respondents followed a patient with meningitis in the last year. A 49.5% of participants preferred to perform computerized cranial tomography (CCT) for suspected meningitis cases before lumbar puncture (LP) at 75-100% frequency (27.5% PAS; 72% APS, p < .01). In addition 27.1% of the respondents reported using a routine steroid as an adjunctive treatment (19% PAS; 35% APS, p < .01). For meningococcal meningitis, 72.5% of the participants preferred to use third-generation cephalosporins (63.1% PAS; 82.1% APS, p < .05). For pneumococcal meningitis, approximately 50% of the participants preferred to use a third-generation cephalosporin plus glycopeptide (41.5% PAS; 58.9% APS, p < .05). While 32.7% of the sample preferred to administer a 7-day course of antibiotics for meningococcal meningitis, 40.9% preferred a course of 14 days or more. For pneumococcal meningitis, 88.4% of the sample preferred a 10-14 day course of antibiotics. In addition, 67% of the PAS group and 50% (p < .001) of the APS group thought that a conjugated meningococcal vaccine should be a part of the National Immunization Program. The top five groups recommended for routine immunization included all children, asplenia/splenectomy patients, immunodeficient patients, those who planned to travel to endemic areas, including Hajj, and military personnel. CONCLUSION In this large convenient sample of physicians in Turkey, we showed that there are heterogenous approaches to the diagnosis and treatment of bacterial meningitis, also differences between pediatricians and non-pediatricians regarding their beliefs and attitudes, which may be due to differences in the epidemiology and clinical presentation between children and adults. We observed appropriate but unnecessary extended courses of antibiotics for meningitis. Most of the participants thought that children are a vulnerable risk group that should potentially be immunized and that meningococcal vaccines should be included in the National Immunization Program. Our results imply that more awareness is needed regarding diagnosis, treatment, and further recommendations for meningitis at the country level in Turkey.

Abstract
BACKGROUND The aim of this study was to investigate the prevalence of menstruation-related headache and the impact of associated factors in adolescents. METHODS This cross-sectional study was conducted in seven randomly selected high schools, and 3,886 girls attending those schools were invited to take part. After the consent of the school principals, a final total of 2,485 girls (63.9%) were involved in the study. A specific questionnaire was distributed to adolescent girls (14-19 years old). The first part of the survey investigated the features of menstruation (age at first menstruation, duration of period, pad fully soaked per day). The last part of the questionnaire surveyed the presence of headache during the menstrual period. The severity of headache was measured using a visual analog scale. Last, participants were requested to complete the Beck Depression Inventory (BDI). The prevalence of menstruation-related headache and associated factors were studied. RESULTS Mean subject age was 15.89 ± 1.07 years (range, 14-19 years) and mean age at menarche was 12.96 ± 1.09 years old. The prevalence of menstruation-related headache was 25.9% (n = 646). Onset of menstruation at <12 years of age, longer duration of menstruation period, dysmenorrhea, daily consumption of coffee and cola and smoking significantly affected the frequency of menstruation-related headache. Mean BDI score was 21.68 ± 13.65 and was significantly associated with menstruation headache. CONCLUSION Menstruation-related headache is a common problem in adolescent girls. It might be associated with different comorbidities such as depression. Accordingly, a multidisciplinary treatment approach must be considered to improve the quality of life.

Abstract
The aim of this study was to evaluate the age-appropriate immunization coverage in 366 children with chronic neurological disease (CND), to evaluate the use of vaccines not included in routine program, to evaluate serological tests for vaccine-preventable diseases and to describe the related factors in unvaccinated children. 95.6% of all children with had received age-appropriate vaccinations according to the actual National Immunization Program (NIP) during childhood. 12 children (3.6%) had not received vaccines; only two had true contraindications. Because most of the vaccines have been implemented through the NIP for 10 years in Turkey, 88% of children required these new vaccines or booster doses. Moreover, 86.6% of the children and 92.6% of household contacts had no prior history of influenza vaccine. Furthermore, 88% of the patients had not received the varicella vaccine, and the anti-varicella IgG levels were only negative in 27.9%. In addition, 18.6% of the children were negative for anti-mumps IgG, 23.7% for anti-measles IgG, and 6.3% for anti-rubella IgG. Anti-HBs IgG level was 0-10 IU/L in 45.6% of the patients (most of them previously vaccinated) and 79.8% were negative for hepatitis A IgG antibodies. For pertussis infection, the antibody titers of 54.1% of patients were below the protective level, and 10% of patients had a prior acute pertussis infection. Therefore, it is suggested that children with CND should be evaluated for their vaccination status during their first and follow-up visits at certain intervals, and their primary immunization should be completed; moreover, many will need revaccination or booster doses.

Abstract
The serogroup epidemiology of invasive meningococcal disease (IMD), which varies considerably by geographic region and immunization schedule, changes continuously. Meningococcal carriage data are crucial for assessing IMD epidemiology and designing f potential vaccination strategies. Meningococcal seroepidemiology in Turkey differs from that in other countries: serogroups W and B are the predominant strains for IMD during childhood, whereas no serogroup C cases were identified over the last 10 y and no adolescent peak for IMD was found. There is a lack of data on meningococcal carriage that represents the whole population. The aims of this multicenter study (12 cities in Turkey) were to evaluate the prevalence of Neisseria meningitidis carriage, the serogroup distribution and the related risk factors (educational status, living in a dormitory or student house, being a household contact with Hajj pilgrims, smoking, completion of military service, attending bars/clubs) in 1518 adolescents and young adults aged 10-24 y. The presence of N. meningitidis DNA was tested, and a serogroup analysis was performed using polymerase chain reaction. The overall meningococcal carriage rate was 6.3% (n = 96) in the study population. A serogroup distribution of the 96 N. meningitidis strains isolated from the nasopharyngeal specimens revealed serogroup A in 5 specimens (5.2%), serogroup B in 9 specimens (9.4%), serogroup W in 64 specimens (66.6%), and serogroup Y in 4 specimens (4.2%); 14 were classified as non-grouped (14.4%). No serogroup C cases were detected. The nasopharyngeal meningococcal carriage rate was 5% in the 10-14 age group, 6.4% in the 15-17 age-group, and 4.7% in the 18-20 age group; the highest carriage rate was found in the 21-24 age group (9.1%), which was significantly higher than those of the other age groups (p < 0.05). The highest carriage rate was found in 17-year-old adolescents (11%). The carriage rate was higher among the participants who had had close contact with Hajj/Umrah pilgrims (p < 0.01) or a history of upper respiratory tract infections over the past 3 months (p < 0.05). The nasopharyngeal carriage rate was 6.3% among adolescents and young adults in Turkey and was similar to the recent rates observed in the same age groups in other countries. The most prevalent serogroup was W, and no serogroup C cases were found. In conclusion, the present study found that meningococcal carriage reaches its peak level by age 17, the highest carriage rate was found in 21 - to 24 - year-olds and the majority of the carriage cases were due to serogroup W. Adolescents and young adult carriers seem to be a potential reservoir for the disease, and further immunization strategies, including adolescent immunization, may play a role in the control of IMD.

Abstract
Background New (mobile phones, smartphones, tablets, and social media) and traditional media (television) have come to dominate the lives of many children and adolescents. Despite all of this media time and new technology, many parents seem to have few rules regarding the use of media by their children and adolescents. Objectives The aim of this study was to evaluate media access/use of children and to evaluate beliefs and attitudes of parents concerning the use of old and new media in Turkey. Methods This is a cross-sectional electronic survey of a national convenience sample in Turkey via SurveyMonkey, including 41 questions regarding topics relevant to television, computers, mobile phones, iPad/tablet use, and social media accounts. Results The responses of the 333 participants (238 women, 95 men; 27-63 years) were evaluated. The average daily watching alone time was 0 to 2 hours among 53.4% (46/86), and daily coviewing time with parents of children was 0 to 2 hours among 62.7% (54/86) of children below 2 years of age. Regarding parents’ monitoring their children’s computer use (n=178), 35.4% (63/178) of the parents prefer coviewing, 13.5% of the parents use a family filter (24/178), and 33.1% (59/178) of the parents prefer to check Web history. Approximately 71.2% (237/333) of the participants had an iPad/tablet in the house, 84.3% (200/333) of the parents give their children permission to use the iPad/tablet. Of the parents, 22.5% (45/200) noted that their children used the iPad/tablet at the table during lunch/dinner and 57.9% (26/45) of these children were aged 5 years and below. Of parents, 27.3% (91/333) agreed that the optimal age for owning a mobile phone was 12 years, and 18.0% (60/333) of the parents noted that their children (one-third was below 2 years) used the mobile phone at the table during meals. A total of 33.3% (111/333) children/adolescents have a Facebook profile, and 54.0% (60/111) were below 13 years of age. Approximately 89.2% (297/333) of the parents emphasized that the Internet is essential for their child’s education. Discussion According to our study results, knowledge regarding the use of old and new media is limited among the parents in Turkey. Our study showed that screen time and mobile device use (including during meals) are common in children below 2 years of age, whereas no screen time was recommended for children below 2 years of age. We concluded that there is need for evidence-based guidelines regarding the use of the Internet and social media for parents and parents should ensure that there is a plan in place for the use of children’s media.

Abstract
Anogenital warts related to human papillomavirus (HPV) have been observed in children. Definition of the transmission mode, therapy, and follow-up for long term potential complications is important. A 27-month old girl was admitted with multiple pedunculated red-purple colored cauliflower-like lesions of 1.5 years duration. Clinical/histopathological and microbiological diagnosis was condyloma acuminate due to HPV type 16. After 12 weeks of imiquimod 5% cream application (pea-sized) overnight three times per week, the perianal warts had completely disappeared. The mode of transmission of HPV 16 in our case was probably horizontal, related to the sharing of common personal hygiene items in the women’s shelter. We report herein the case of an infant living in a women’s shelter with giant condyloma acuminata due to HPV 16, which was successfully treated with topical imiquimod therapy. This patient should be followed up for recurrence and potential malignant lesions related to HPV type 16.

Abstract
OBJECTIVE The aim of the present study was to evaluate the serum and urinary levels of leptin and ghrelin in children with primary idiopathic nephrotic syndrome (NS), to compare these results between patients during the relapse and remission phase and to evaluate the possible role of leptin and ghrelin in the pathogenesis of NS. PATIENTS AND METHODS Forty-nine children with primary idiopathic NS (25 children with relapse and 24 children in remission), who were followed up at the Pediatric Nephrology Unit, enrolled. Twenty-eight age- and sex-matched healthy children served as controls. Serum and urinary leptin levels were determined by immunoenzymatic ELISA, and serum and urinary ghrelin levels were determined by the RIA method. RESULTS The serum leptin levels were significantly lower in the children with NS during the relapse phase than in the children with NS during remission or in the controls (1.42±0.34 ng/dl and 3.60±0.70 ng/ml; p<0.01, 1.42±0.34 ng/ml and 5.27±4.67 ng/ml; p<0.001, respectively). The urinary leptin excretion levels were significantly higher in the relapse group than in the controls (0.40±0.11 ng/ml and 0.12±0.06 ng/ml, p<0.01, respectively). The serum ghrelin levels were similar between the study groups (p>0.05). The urinary ghrelin excretion levels were significantly higher in the relapse group than in the remission group and the controls (965.0 pg/ml [93-3711] and 679.7 pg/ml [93-3783], p<0.05; 965.0 pg/ml [93-3711] and 387.7 pg/ml [114-1214], p<0.001, respectively). The urinary ghrelin levels were also significantly higher in the remission group than in the controls (679.7 pg/ml [93-3783] and 387.7 pg/ml [114-1214]), p<0.01, respectively). The serum leptin levels were positively correlated with the serum albumin levels (r=0.440, p<0.05) and were negatively correlated with the serum triglyceride levels during the relapse phase. The urinary leptin and ghrelin levels were positively correlated with proteinuria in the relapse group. CONCLUSIONS We propose that leptin plays a role in the pathophysiology of NS and is associated with proteinuria, hypoproteinemia and hyperlipidemia. The significant urinary excretion of ghrelin in children with NS is possibly due to underlying pathophysiological changes, and normal serum ghrelin levels might be associated with an unknown compensatory mechanism.

Abstract
Adrenal insufficiency associated with cytomegalovirus (CMV) is a well-described condition in adults with AIDS, however there is little information about CMV-associated adrenal insufficiency in childhood. The cases of two infants with negative HIV serology, presenting with CMV-associated adrenal insufficiency, are described. Clinical findings and therapeutic interventions are discussed with reference to the affinity of CMV infection for the adrenal gland. The differential diagnosis of adrenal insufficiency in newborns and infants should include CMV infection, and clinical suspicion of CMV-associated adrenal insufficiency should lead to early initiation of appropriate adrenal substitution therapy and ganciclovir antiviral therapy. Timely therapy for CMV-associated adrenal insufficiency can be lifesaving.

Abstract
Wiedemann-Rautenstrauch syndrome (WRS) is a rare autosomal recessive condition which represents a complex of symptoms and laboratory findings with unknown cause and pathogenesis. Approximately 30 patients with WRS have been reported. We report here two newborns with WRS from Turkey with clinical and laboratory findings including bone marker evaluation. Our two patients had characteristic features of WRS, including intrauterine growth retardation, aged appearance, near absence of subcutaneous fat, gluteal fat pads, also labial pad in the first infant, wrinkled thin skin, sparse scalp hair, prominent scalp veins and facial dysmorphism. They also have severe osteopenia and elevated urinary deoxypyridinoline levels which have not been previously described in patients with WRS. Impaired lipid and hormone profiles including elevated prolactin and triglyceride level have been reported in patients with WRS. Our first patient also has excessive joint contractures, persisting thrombocytosis and rectal prolapse. We evaluated bone mineral findings in our two patients with WRS and recommend caution when handling children with WRS.

Abstract
Axial mesodermal dysplasia spectrum (AMDS) includes the features of other malformation complexes or sequences, such as oculo-auriculo-vertebral spectrum (OAVS) and sacral dysgenesis. We describe a new patient, an infant born to a type 1 diabetic mother, with the phenotype of AMDS as well as severe congenital cardiac anomalies including transposition of the great arteries and an atrioventricular septal defect. Congenital heart defects had been reported with OAVS, sacral dysgenesis, and in an infant born to a diabetic mother and combinations of these findings have been reported in the same patient. To our knowledge, this is the first patient with AMDS with transposition of great arteries and an atrioventricular septal defect and the second patient with AMDS who had history of parental consanguinity. The mechanism through which maternal diabetes mellitus leads to malformations is not entirely clear, but the glycemic control is essential in the care of mothers.

Abstract
Recent findings have focused on the possible role of linezolid as a suitable candidate for the treatment of central nervous system infections. The linezolid treatment for meningitis was sporadically reported in adults but there was no report in children. Here, we present a 6-month-old boy with meningitis and subdural empyema which was unresponsive to more conventional agents but successfully treated with linezolid therapy. A previously healthy 6-month-old boy was referred to our clinic for deteriorating general condition with fever, vomiting and seizures. He had fever and tense-bulging anterior fontanelle. Based on his first cerebrospinal fluid (CSF) results, empirical antibiotic therapy for bacterial meningitis consisting of vancomycin and ceftriaxone was started. However, CSF culture yielded no micro-organisms but blood culture showed coagulase-negative Staphylococci. On the 7th day, he still had high fever and the erythrocyte sedimentation rate (ESR) and serum CRP levels had risen by 105 mm/h and 36.2 mg/dl, respectively. On 10th day, computerized cranial tomography showed bilateral frontoparietal subdural empyema. Purulent material was evacuated by burr hole, and gram stains of the material showed polymorphonuclear leukocytes and no microorganisms. Clinical and CSF findings of our case were, unresponsiveness to vancomycin, ceftriaxone and consecutive meropenem treatment while we still observed subdural empyema during these treatments. For this reason we started linezolid 10 mg/kg twice daily. Clinical signs improved dramatically, with both completely normal neurological findings and normalization of CSF and radiological findings. To the of our best knowledge, linezolid treatment of meningitis in children has not been reported previously. Clinical and CSF findings of our case were improved completely with linezolid treatment. Also, control cranial computerized tomography showed the total recovery of subdural empyema. Here we present the youngest case with meningitis which was successfully treated with linezolid treatment.
