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.

Prevalence of some risk factors in children with epilepsy compared to their controls

AIM The goal of this case-control study was to identify the significance of certain risk factors for epilepsy in Turkey. METHOD A total of 805 cases, aged 1-16 years, followed-up for epilepsy at the Pediatric Neurology Department and a control group consisting of 846 age-matched cases without epilepsy were included in the study. The risk factors examined were gender, neurological impairment, febrile convulsion, head trauma, central nervous system infections, parental consanguinity, family history of epilepsy, prenatal and natal risk and newborn jaundice. Data regarding the investigated epilepsy risk factors were obtained through a questionnaire via personal interviews and the medical records and were assessed using univariate and multivariate analysis. RESULT Univariate analysis showed an increased risk for epilepsy with a history of atypical febrile seizure (21.97-fold), severe and moderate head injury (27.76- and 7.09-fold respectively), CNS infection (4.76-fold), history of epilepsy in first-, second- or third-degree relatives (6.42-, 3.09- and 2.66-fold, respectively), presence of maternal hypertension (4.31-fold), an apgar score < or =6 at any time (7.78-fold) and neonatal jaundice (3.12-fold). Abnormal neurological signs increased the epilepsy risk 5.92 times in univariate analysis and 30.26 times in multivariate analysis. CONCLUSION The most important risk factors for epilepsy in this study were neurological impairment, history of atypical febrile seizures, severe head injury and a low apgar score. Other important risk factors were moderate head trauma and a history of epilepsy in the family.

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.

Establishment of interdisciplinary child protection teams in Turkey 2002–2006: Identifying the strongest link can make a difference!

OBJECTIVES The University of Iowa Child Protection Program collaborated with Turkish professionals to develop a training program on child abuse and neglect during 2002-2006 with the goals of increasing professional awareness and number of multidisciplinary teams (MDT), regional collaborations, and assessed cases. This paper summarizes the 5-year outcome. METHODS A team of instructors evaluated needs and held training activities in Turkey annually, and provided consultation when needed. Descriptive analysis was done via Excel and SPSS software. RESULTS Eighteen training activities were held with 3,570 attendees. Over the study period, the number of MDTs increased from 4 to 14. The MDTs got involved in organizing training activities in their institutions and communities. The number of medical curriculum lectures taught by MDTs to medical students/residents, conferences organized by the MDTs, and lectures to non-medical professional audiences increased significantly (R(2)=91.4%, 83.8%, and 69.2%, respectively). The number of abuse cases assessed by the MDTs increased by five times compared to pre-training period. CONCLUSIONS A culturally competent training program had a positive impact on professional attitudes and behaviors toward recognition and management of child abuse and neglect in Turkey. The need to partner with policy makers to revise current law in favor of a greater human services orientation became clear. PRACTICE IMPLICATIONS Pioneers in developing countries may benefit from collaborating with culturally competent instructors from countries with more developed child protection systems to develop training programs so that professional development can improve recognition and management of child abuse and neglect.

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 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 cows 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.

Toilet training in Turkey: the factors that affect timing and duration in different sociocultural groups.

BACKGROUND The aim of the present study was to determine the patterns of toilet training and the factors that may be related to its timing and duration and the approaches of different sociocultural groups within a developing country. METHODS This cross-sectional survey was performed on 745 children who live in three different sociocultural settlements. The factors that might have affected initiation and completion age and duration of toilet training were assessed with t-test, ANOVA and logistic regression analysis. RESULTS Mean initiation and completion ages were 22.05 +/- 6.73, 28.05 +/- 8.40 months respectively. The families living in rural and semi-urban settlements, mothers educated for less than 5 years, unoccupied mothers, children living in houses which do not have a toilet inside, families who use washable diapers, who use Turkish style toilets and who use punishment methods started training earlier. In the infants whose mothers had an education over 12 years, completion age was later than others and the earliest completion age was seen in families who used punishment method. Mean duration needed to complete toilet training was 6.84 +/- 7.16 months. The duration of training was longer in families living in rural and semi-urban settlements, mothers educated for less than 5 years, unoccupied mothers, children living in houses which do not have a toilet inside, families who use washable diapers and when the initiation was before the child was 18 months old. CONCLUSION Toilet training shows differences among cultures. The age of initiation may be increased as the parents are educated better and a child-orientated approach becomes more popular than the parent-orientated approach.

Are the neonatal outcomes similar in large-for-gestational age infants delivered by women with or without gestational diabetes mellitus?

BackgroundInfants are considered large for gestational age (LGA) if their birth weight is greater than the 90th percentile for gestational age and they have an increased risk for adverse perinatal outcomes. Maternal diabetes is one of the factors affecting birthweight. However there are limited data on the perinatal outcomes of infants of gestational diabetic mothers. The aim of the present study was to compare the neonatal outcomes of LGA infants delivered by women with and without gestational diabetes mellitus.MethodsThis was a retrospective study of LGA infants of ≥36 weeks of gestation born at the Gazi University Medical School Hospital during the period of 2006–2009. Neonatal outcomes included hypoglycemia and polycythemia in the early neonatal period and hospital admissions. The Chi-square and Student’s t test were used for comparing variables.ResultsSeven hundred eligible infant-mother pairs were enrolled in the study. Eighty-seven of them (12.4%) were infants of gestational diabetic mothers and 613 (87.6%) were infants of non-diabetic mothers. The incidence of hypoglycemia at the first hour was higher in infants of diabetic mothers (12.8%) than in infants of non-diabetic mothers (5.3%) (P=0.014). Polycythemia was also more frequently observed in infants of the gestational diabetic mothers (9.3%) than in infants of the non-diabetic mothers (3.0%) (P=0.010). Although overall hospital admission rates were not different between the two groups, infants of diabetic mothers were more likely to be admitted because of resistant hypoglycemia (P=0.045).ConclusionsThe results of this study suggested that LGA infants of mothers with gestational diabetes mellitus were at a greater risk for hypoglycemia and polycythemia in the early neonatal period than LGA infants of nondiabetic mothers.

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.
