The assessment of the knowledge and practices of healthcare providers regarding paroxysmal non-epileptic events (PNES) in children: A cross-sectional study.

OBJECTIVE: Paroxysmal non-epileptic events (PNEs) are a group of disorders that may be misdiagnosed as epilepsy. This study has aimed to assess the knowledge and practices of family physicians and pediatricians regarding the diagnosis, treatment, and follow-up of PNEs in children. METHODS: The study was designed as a prospective cross-sectional study that was conducted between March 1, 2022, and June 1, 2022, by reaching pediatric specialists and assistants, family physicians, subspecialty assistants, and subspecialists using a Google questionnaire. The survey consists of 26 questions. The questionnaire used by the researchers was prepared in accordance with the literature search and it included detailed questions on the diagnosis, treatment, and differential diagnosis of PNEs. RESULTS: A total of 37.3% worked as specialists. Most of the participants (41.3%) have worked in training and research hospitals, and 44.3% have been physicians for 6-10 years. The mean and standard deviation for the total score were 10.1 ± 2.6. The scores of family physicians were statistically lower than those of specialists, subspecialty assistants, and subspecialists. A total of 67.2% left the decision of whether the patient should stop taking their medication to another clinician. 45% of the doctors said that they were uncomfortable with the diagnosis. SIGNIFICANCE: The study findings emphasized the significant knowledge gap among healthcare providers regarding PNEs in children, highlighting the need for targeted educational interventions to improve their understanding and diagnostic skills in this area.

Comparison of melamine exposure by feeding practices in babies aged 0-6 months.

This study was conducted to estimate the daily dietary intakes of melamine for human milk-fed (HMF) babies and mixed-fed (MF) babies. It was carried out in 70 mother-baby pairs (40 babies in the HMF group and 30 babies in the MF group). Human milk, formula milk, and baby urine samples were collected to assess the dietary exposure of babies. Melamine concentrations were analyzed by using a competitive enzyme-linked immunosorbent assay. Melamine was determined in 82.5 % of the human milk samples in the HMF group (median: 0.75 µg/L) while it was present in 96.7 % of human milk samples (median: 1.25 µg/L) and 96.7 % in formula milk samples (median: 0.95 µg/kg) in the MF group. The mean urinary melamine concentration of HMF babies (1.20 ± 0.21 µg/L) was not significantly different than MF babies (1.35 ± 0.49 µg/L). Melamine exposure was calculated as 0.12 µg/kg bw/day and 0.24 µg/kg bw/day in HMF and MF babies, respectively. Melamine exposure in both groups was below the tolerable daily intake. There were no significant associations between melamine exposure and various features of babies and mothers. As a result, it can be suggested that Turkish babies (aged 0-6 months) are not at risk for high melamine exposure through the diet.

Parental vaccine knowledge and behaviours: a survey of Turkish families.

BACKGROUND: Personal and herd immunity require durability in high vaccination coverage rates, and this mainly depends on the interaction between parental and service/provider factors. AIMS: The aim of this study was to assess Turkish parents' knowledge and behaviours concerning childhood vaccination and their association with familial sociodemographic characteristics. METHODS: A cross-sectional survey, including a questionnaire, was conducted with parents of children aged between 1 day and 120 months. RESULTS: Of the 903 index children, 881 (97.6%) were up to date for all vaccinations by age. Demographic variables were not related to belief in protection through vaccination or rejection of obligatory vaccines. Mean age, education level, occupation of mother (P = 0.006, P < 0.001, and P = 0.01, respectively) and father (P = 0.002, P < 0.001, and P = 0.006, respectively), average monthly household income (P < 0.001), and experience of vaccine side-effects (P = 0.02) were associated with knowledge about optional childhood vaccines. Father's education level was independently associated with knowledge about optional childhood vaccines. CONCLUSIONS: Having any experience of vaccine side-effects and parental sociodemographic characteristics, especially father's education level, affect Turkish parents' knowledge of childhood optional vaccines.

Maternal Height and Infant Body Mass Index Are Possible Risk Factors for Developmental Dysplasia of the Hip in Female Infants.

Developmental dysplasia of the hip (DDH) is a wide-spectrum disease with a multifactorial etiology and, despite its prevalence, no definitive etiology has yet been established. The aim of this study was to investigate new risk factors for DDH by evaluating newly defined potential risk factors. A total of 71 infants were separated into 2 groups:Group I, 28 female first-born infants diagnosed with DDH and their mothers;and Group II, 43 healthy female first-born infants and their mothers. The maternal height and weight before pregnancy, infant height and weight at birth, and body mass index (BMI) of both mother and infant were determined. Calculations were made of the ratios between these parameters. Of the examined risk factors, only maternal height and the ratio of maternal height to infant BMI (MH/I-BMI) were found to be significant for DDH in infants. In conclusion, the results of this study show that a short maternal height and a low MH/I-BMI increase the risk of DDH. Further studies with a larger series are necessary to confirm these results.

Defecation patterns of the infants mainly breastfed from birth till the 12th month: Prospective cohort study.

BACKGROUND/AIMS: Studies about defecation patterns have been mostly conducted on infants who were breastfed in a short term but were fed predominantly with formula. In this study, defecation patterns of 125 infants, most of them being breastfed during 12th month were evaluated. MATERIALS AND METHODS: Frequency, consistency and color of the stool were analyzed in relation to the feeding pattern at the 15th day and at the 1st, 2nd, 3rd, 4th, 5th, 6th and 12th months. RESULTS: Frequency of defecation was highest in 15th day with a median of 6/day. It decreased with age (p=0.0001), being 4/day and 3/day in 1st and 2nd months respectively, and 2/day between 3rd-12th months. During first 5 months, the stool frequency was higher in infants who were exclusively breastfed compared to those being fed with breastfed and formula (p<0.05). The effect of the feeding pattern on stool frequency disappeared in the following months (p>0.05). Stool frequency decreased by half at the 2nd month when the rate of less than once/day attained its highest value (24.8%). In those who had a rate of less than once/day, stool frequency stayed low until the 6th month and exclusively breastfed rate was also found lower (p<0.05). CONCLUSION: Besides the age, exclusive breastfeeding was also effective on stool frequency. It points out that infants who are fed with formula in addition to breastfeeding may defecate less than once per day hence should not be diagnosed as having constipation depending solely on defecation frequency and should not receive unneccesary treatments.

Immunogenicity of a Haemophilus influenzae type b-tetanus conjugate vaccine when administered separately or in combined vaccines for primary immunization in two consecutive national schedules in Turkey.

BACKGROUND: In Turkey, the Haemophilus influenzae type b-tetanus toxoid conjugate vaccine (Hib) was replaced by the combined diphtheria-tetanus-acellular pertussis and inactivated polio vaccine (DTaP-IPV/Hib) in 2008. This shift to the new schedule created different cohorts of vaccinated children as a consequence of the different schedules used. We evaluated the immunogenicity of the Hib vaccine in infants vaccinated with these different schedules. METHODS: Three groups of children were evaluated: group 1 comprised 145 infants vaccinated with diphtheria, tetanus, and whole cell pertussis (DTwP), oral polio vaccine (OPV), and Hib vaccines simultaneously at separate sites; group 2 comprised 204 infants vaccinated with the DTaP-IPV/Hib combined vaccine; group 3 comprised 100 infants vaccinated with a mixed schedule of DTwP, OPV, and Hib for the first one or two doses, followed by DTaP-IPV/Hib vaccine to complete the series. RESULTS: Anti-polyribosylribitol phosphate (anti-PRP) titers ≥0.15µg/ml were similar in groups 1, 2, and 3. However, in group 1, who received all the vaccines at separate sites, ≥ l.0µg/ml long-lasting antibody titers and anti-PRP geometric mean titers were higher (p=0.001). CONCLUSION: This study showed that even one dose administered in combination with other vaccines in a primary series decreased the level of anti-PRP.

The rate of seasonal influenza vaccination in diabetic children, the effect of recommendation and the factors influencing the acceptance of recommendation: an interventional study.

OBJECTIVE: To investigate the vaccination rate of influenza in diabetic children and the effect of recommendation and other factors on vaccination rate. MATERIAL AND METHODS: On July 2011, 144 diabetic children and their families were informed about and were recommended to receive the influenza vaccine every year, in September. On December 2011, parents were questioned about the vaccination. RESULTS: Influenza vaccination rate of the previous season (28.3%) increased to 50.0% (p<0.05). Receiving the vaccine in 2010 was the only contributing factor to the recommendation success. The reasons given by the non-receivers were; forgetting (50.0%), fear of adverse-effects (26.4%), not believing in usefulness (15.2%), rejection by the child (4.2%) and effects of media (4.2%). 88.9% of those who forgot declared that they would receive if they were reminded at the beginning of the season. CONCLUSION: The rate of influenza vaccination was low. The majority of those who didn't recieve the vaccination declared that they would if they were reminded at the beginning of the season and the fact that "receiving the vaccine in 2010" was the only factor influencing the recommendation success indicate that recommending isn't enough but that reminding and giving detailed information about the vaccine will increase vaccination rates independent of other factors.

New opportunity for vaccinating older people: well-child clinic visits.

BACKGROUND: Streptococcus pneumoniae causes considerable morbidity and mortality in the elderly. As aging of the population is making the health of the elderly a universal priority, preventive measures, such as vaccination, will become increasingly important. METHODS: We designed a prospective interventional study to determine whether recommendations to vaccinate grandparents of children attending well-child clinics would increase the pneumococcal vaccination rate in the elderly. Children younger than 5 years of age, attending a university well-child clinic from 1 May to 31 September 2008 who had grandparents over 65 years of age were eligible. A survey including the questions about the demographic characteristics of children, their parents and grandparents over 65 was carried out by face-to-face interview with the parents. High-risk medical conditions and vaccination history of grandparents was also noted and the benefits and necessity of pneumococcal vaccination (23vPPV) for the elderly was emphasized. Four months later these families were contacted to determine whether this intervention had increased the pneumococcal vaccination rates of the elderly. RESULTS: Information was obtained from 938 grandparents of 545 children. Before the interview, among all grandparents, only 0.9% were vaccinated with 23vPPV. Four months after this intervention, immunization coverage increased to 19.1%. The sex of the grandchild (OR: 1.99) and previous hepatitis B or influenza immunization of the grandparents (OR: 2.73) were the significant parameters accounting for higher immunization rates. CONCLUSION: Reminding elderly grandparents about vaccines in well-child clinics could be an opportunity in this field.

Growth patterns of large, small, and appropriate for gestational age infants: impacts of long-term breastfeeding: a retrospective cohort study.

BACKGROUND: In several studies, since high and low birth weights are demonstrated as associated with obesity in childhood, these values should be followed up and documented carefully. OBJECTIVE: The aim of this retrospective cohort study is to demonstrate the variation on body mass index outcomes of large (LGA), small (SGA), appropriate (AGA) for gestational age infants from birth to the end of fourth year of age and the effects of breastfeeding duration on these outcomes. METHODS AND RESULTS: Four hundred and seven infants were recruited in the study (304AGA, 85 LGA, 18 SGA infants). LGA was frequent in boys and SGA in girls (p = 0.001). The mothers with gestational diabetes mellitus did have LGA infants (10.0% vs. 3.3%) (p = 0.022). The SGA infants performed rapid catch-up growth in the second month while the LGA infants performed catch-down growth in the ninth month. After the first 4 months, there was no difference on the values of BMI depending on breastfeeding time, less or more than 4 months, on the basis of the AGA and LGA infants. However, the body mass index (BMI) of LGA infants breastfed more than 12 months were not different from the AGA; unless the breastfeeding ceased earlier, the means of BMI remained significantly higher until 3 years. CONCLUSION: Consequently, long duration of breastfeeding might protect LGA infants from childhood obesity risk.

Factors associated with parental acceptance and refusal of pandemic influenza A/H1N1 vaccine in Turkey.

The objective of this study was to investigate the parents' attitudes towards and identify the possible factors associated with pandemic H1N1 vaccine uptake that was recommended to children between 6 months and 5 years of age. A questionnaire exploring the attitudes of parents to H1N1 vaccine was given to parents of children 6 through 60 months of age attending to Akdeniz and Gazi University Hospitals' well-child departments between 15 November 2009 and 15 January 2010. The questionnaire included questions on demographic characteristics, parental perception of the severity of the pandemic, the presence of anyone in their environment who suffered from pandemic influenza, their decision on whether or not to vaccinate their child, the factors that influenced them during decision-making process and possible factors that might have influenced the opponents of their decision. Those who accepted to get their children vaccinated got it immediately, free of charge. Out of 611 parents who responded the questionnaire 226 (36.7%) had their children vaccinated. Parental education period of less than 12 years, not being a close relative of a health care worker, not having a relative who suffered from the disease, having a child younger than 36 months, being influenced by the relatives' opinions or from the politicians or from the media all decreased vaccine acceptance. Factors that were most significantly associated with vaccine refusal were thinking that the pandemic was exaggerated (OR 9.44, 95% CI 4.28-20.82) and believing that other preventive measures were more effective than H1N1 vaccine (OR 15.61, 95% CI 7.37-33.08). Lessons learned from influenza H1N1/2009 pandemic may help national authorities, health care providers and media on how to keep the public well informed and find ways of better risk-benefit communication with the parents on vaccines.

Diagnostic value of rapid antigen detection test for streptococcal pharyngitis in a pediatric population.

Acute upper respiratory tract infections in children may result in overuse of antibiotics as throat culture cannot be performed in every setting and results cannot be obtained early. A rapid and reliable test might decrease unnecessary antibiotic usage. The purpose of this study was to determine the prevalence of group A beta-hemolytic Streptococcus (GABHS) infections in different pediatric age groups and to assess the diagnostic value of rapid antigen detection test (RADT) for streptococcal pharyngitis. This study was performed in a pediatric outpatient clinic. All children who were admitted with signs and symptoms of acute upper respiratory tract infections were included in the study. Throat culture and RADT were performed and prevalence of GABHS was assessed. Diagnostic value of RADT was determined. This study included 1248 children with a mean age of 6.3+/-3.6 years. There were 655, 518, and 75 children in age groups of 0-6, 7-12 and 13+ years, respectively. The overall prevalence of GABHS was 38.1% (475/1248), as judged by throat culture. The prevalence was highest in the 7-12-year age group (53.9%) and lowest in the 0-6-year age group (25.2%). Considering all patients, RADT gave a sensitivity of 89.7%, specificity of 97.2%. The sensitivity and specificity of RADT were similar in different age groups (p values >0.05). Diagnostic value of RADT is high and can be used safely in populations where streptococcal pharyngitis and its complications such as acute rheumatic fever and acute glomerulonephritis are common.

Nasopharyngeal carriage of Streptococcus pneumoniae in healthy Turkish infants.

OBJECTIVES: The aims of this study were to determine nasopharyngeal carriage rates, serotype distribution and antimicrobial resistance patterns of Streptococcus pneumoniae in healthy 0 to 2 year-old infants who live within a rural or urban locale and not attending daycare centers. In order to evaluate the possible impact of pneumococcal conjugate vaccine in this population, coverage of the isolated serotypes by the vaccine was also calculated. METHODS: The study was conducted on 564 healthy infants attending 2 different well child clinics, one of which is located in an urban region and the other in a rural region. Specimens were collected with nasopharyngeal swabs. Serotyping was performed with standard antisera. Penicillin susceptibility was determined with E-test. Chi-square tests and logistic regression were used for data analysis. RESULTS: The pneumococcal carriage rate was 22.5%. Age (>2 months age) [2.98 (1.41-6.29) p=0.004] and presence of another child within the house who attends school [1.72 (1.13-2.62) p=0.01] increased the carriage rate. The most frequently isolated serotypes were 11 (11.8%), 23 (7.9%), 19F (7.1%), 22 (6.3%), 9 (5.5%), 19 (5.5%) and 23B (5.5%). The total coverage of vaccine and vaccine-related serotypes by 7, 11 and 13 valent pneumococcal conjugate vaccines were 51.2, 59.0 and 59.0%, respectively. Of the isolated pneumococci, 10 (8.5%) were intermediately resistant and 8 (6.8%) were highly resistant to penicillin. CONCLUSION: This study provides data about the local carriage rate and serotype distribution of S. pneumoniae strains in Turkish children, which is important in predicting the possible effects of different valent pneumococcal conjugate vaccines in this population.

Factors associated with defecation patterns in 0-24-month-old children.

To identify the normal defecation patterns and the factors affecting these patterns in the first two years of life, a questionnaire was given to the parents of 1,021 children who were followed in a well-child clinic. The time of first meconium passage, presence of colic symptoms, frequency, color, and consistency of stools were recorded.Mann Whitney U, Wilcoxon, chi-square, and correlation tests were used in the statistical analyses. The median number of defecations per day was six in the first month of life. This decreased to once in the second month and almost all cases remained so until the end of the 24th month. At the second month of age, 39.3% of infants passed stools less than once a day. This pattern of rare defecation was seen until the end of 6 months, when supplemental foods were started. Stool frequency was higher in exclusively breast-fed infants (p = 0.0001). Infants who had colic symptoms in the first 2 months had less frequent defecation during the first 2 years of life (p = 0.0001). In addition to confirming the previously observed defecation patterns of 0-2-year-old infants, this study provides the relationship between colic symptoms and stool frequency, and showed that the second month of life was unique in the sense that the frequency of stooling decreased to half of the previous month and 39.3% of these infants defecated less than once a day.

Factors affecting the timing of teething in healthy Turkish infants: a prospective cohort study.

BACKGROUND: Teething is a developmental process and occurs over a broad chronological age range. OBJECTIVE: The objective of this study was to evaluate the effects of feeding pattern and growth parameters on teething time of healthy infants. METHODS: A total of 1200 term newborn infants followed up in Gazi University well-child clinic infants were evaluated, and their growth parameters, feeding patterns, and timing of the eruption of the first tooth were noted. The routine visit times of the clinic were chosen as the cut-off values for teeth eruption for logistic regression analysis for investigating factors that determine the timing of teeth eruption. RESULTS: Timing of the eruption of the first tooth ranged from 4 to 13 months. On the sixth month visit, 24.3%, and on the ninth month visit 84.5% of all infants had at least one tooth. Height-adjusted weight and height percentiles being less than 50, being fed by cow's milk or by formula in the first year, were independent factors negatively influencing teeth eruption by the sixth month, while all but height-adjusted weight percentiles being less than 50 had negative impact on tooth eruption by the ninth month. CONCLUSION: Growth parameters and feeding pattern may be determinants of the timing of teeth eruption in healthy infants.

How to achieve long-term breast-feeding: factors associated with early discontinuation.

OBJECTIVES: To evaluate the factors associated with discontinuation of breast-feeding before 12 months in order to make suggestions for achieving long-term breast-feeding. DESIGN: A descriptive cross-sectional study. SETTING: Gazi University Medical School, Ankara, Turkey. SUBJECTS: Mothers of 1230 children who discontinued breast-feeding at least 15 d before the last visit were asked to fill out a questionnaire about the discontinuation process. Logistic regression analysis was performed to assess the independent effects of factors that might influence breast-feeding discontinuation. RESULTS: Mean breast-feeding duration of the study group was 11.04 (SD 7.45) months. Introduction of bottle-feeding correlated with discontinuation of breast-feeding (r=0.507, P = 0.001). Important risk factors for discontinuation of breast-feeding before the first 12 months were not exclusively breast-feeding at 3 and 6 months, prematurity, not having a plan about breast-feeding duration and maternity leave duration of

Current stretched penile length: cross-sectional study of 1040 healthy Turkish children aged 0 to 5 years.

OBJECTIVES: To update the normal stretched penile length values for children younger than 5 years of age. We also evaluated the association between penile length and anthropometric measures such as body weight, height, and body mass index. METHODS: The study was performed as a cross-section study. The stretched penile lengths of 1040 white uncircumcised male infants and children 0 to 5 years of age were measured, and the mean length for each age group and the rate of increase in penile length were calculated. The correlation between penile length and weight, height, and body mass index of the children was determined by Pearson analysis. RESULTS: The stretched penile length was 3.65 +/- 0.27 cm in full-term newborns (n = 165) and 3.95 +/- 0.35 cm in children 1 to 3 months old (n = 112), 4.26 +/- 0.40 cm in those 3.1 to 6 months old (n = 130), 4.65 +/- 0.47 cm in those 6.1 to 12 months old (n = 148), 4.82 +/- 0.44 cm in those 12.1 to 24 months old (n = 135), 5.15 +/- 0.46 cm in those 24.1 to 36 months old (n = 120), 5.58 +/- 0.47 cm in those 36.1 to 48 months old (n = 117), and 6.02 +/- 0.50 cm in those 48.1 to 60 months old (n = 113). The fastest rate of increase in penile length was seen in the first 6 months of age, with a value of 1 mm/mo. A significant correlation was found between penile length and the weight, height, and body mass index of the boys (r = 0.881, r = 0.864, and r = 0.173, respectively; P = 0.001). CONCLUSIONS: The age-related values of penile length must be known to be able to determine abnormal penile sizes and to monitor treatment of underlying diseases. Our study has provided updated reference values for penile lengths for Turkish and other white boys aged 0 to 5 years.

Effectiveness of inactivated influenza vaccine for prevention of otitis media in children.

OBJECTIVE: The objective of this study was to evaluate the effectiveness of inactivated influenza vaccine in preventing acute otitis media (AOM) and otitis media with effusion (OME) in children aged 6 to 60 months who attend day care. STUDY DESIGN: This prospective, single-blind study was conducted in 8 day care centers in Ankara, Turkey. One hundred nineteen (61 vaccinated and 58 unvaccinated against influenza) healthy children were examined at study entry and at 6-week intervals for 6 months by the same 2 otorhinolaryngologists who were blinded about the vaccination status of the children. The frequency of AOM and OME is compared between the 2 groups and the effect of influenza season on frequency of episodes was evaluated. Based on national influenza laboratory data, the influenza season was determined to be the period between December 15, 2003, and January 31, 2004. RESULT: The frequencies of AOM, OME and total otitis media episodes in vaccinated children were 2.3%, 22.8% and 25.2%, respectively, and these frequencies were 5.2%, 31.1% and 36.3% in the unvaccinated group. The difference was statistically significant (P < 0.01). This difference was especially prominent in the influenza season (P < 0.05). CONCLUSION: Influenza vaccine is effective in reducing AOM and OME episodes in 6- to 60-month-old day care children, especially during influenza season.

Plasma leptin levels in infants of diabetic mothers in fasting and satiety states.

Infants born to diabetic mothers have elevated cord blood leptin levels. The aim of this study was to investigate whether the situation persists at the 2nd postnatal day, taking the fasting and satiety states into account and the influence of fetal exposure to hyperinsulinemia, which are proven important contributing factors to plasma leptin levels. Twenty infants born to mothers with gestational diabetes (Group I) and 20 controls (Group II) were included in the study. Groups were similar for sex and anthropometric measurements. Group I had higher leptin concentrations compared to Group II in fasting and satiety states (p < 0.01). Fasting state leptin levels were significantly lower than seen in satiety in both groups (p < 0.01). There was a positive and significant correlation between leptin concentrations and body mass index of infants. Leptin concentrations were positively correlated with plasma insulin levels in Group I. These findings suggest that plasma leptin levels are high in both fasting and satiety states on the 2nd postnatal day in infants born to mothers with gestational diabetes. The possible mechanism underlying this condition is fetal exposure to hyperinsulinemia due to hyperglycemia. The uniqueness of this report are that fasting and satiety states were taken into account and that the data was collected from the samples taken on the 2nd postnatal day, thus reflecting the exact milieu of the infant excluding the effects of the mother and the placenta.
