Abstract Background The exact etiology of recurrent tonsillopharyngitis in children is not clear. Recurrent tonsillitis in children has multifactorial etiology like most of the diseases in childhood. In this study, our aim was to determine the potential role of vitamin D in recurrent tonsillitis by measuring serum 25-OH vitamin D levels and determining the vitamin D receptor polymorphism among children with recurrent tonsillitis. Methods Eighty-four children with recurrent tonsillitis and seventy-one healthy children aging between 2 and 10 years were enrolled in this study. Serum 25-OH vitamin D level was measured with ELISA and vitamin D receptor gene polymorphism (Apa1, Taq 1, Fok1) was determined by PCR. Serum 25-OH vitamin D level below 50 nmol/L was accepted as deficiency. The vitamin D receptor gene polymorphism in each group was compared. Results The mean age was 5.6 ± 2.4 and 6.1 ± 2.7 years in study and control group, respectively. The average serum 25-OH vitamin D level was 142.7 ± 68.1 nmol/L in study group and 192.3 ± 56.1 nmol/L in control group. There was significant difference between the groups (p < 0.01). In study group, 4.7% (n = 4) of children had serum 25 OH vitamin D levels below 50 nmol/L. None of the children in control group had serum 25-OH vitamin D level below 50 nmol/L. There was no significant differences in vitamin D receptor gene polymorphisms between groups. Conclusion Serum 25-OH vitamin D levels in recurrent tonsillitis group were lower than those in healthy children. But, there was no difference in the incidence of vitamin D receptor gene polymorphism between the two groups.

The surge in recommended vaccinations for child's has spurred the development of combination vaccines, notably hexavalent vaccines, which provide multiple immunizations in a single dose. These vaccines offer various advantages, such as streamlining vaccination schedules, minimizing injection-related pain and exposure to preservatives, expanding vaccine coverage, and reducing administration costs. However, the intricate and expensive development of these vaccines presents substantial challenges, requiring increased investment and healthcare provider education to optimize their utilization and sustain high vaccination rates. Turkey, known for its robust vaccine coverage, strategic geographic location, and the influx of refugees, is at a critical juncture for integrating hexavalent vaccines into national programs. This transition is especially relevant given the rising vaccine hesitancy and the potential resurgence of vaccine-preventable diseases. This review assesses the deployment of hexavalent vaccines, examining their benefits and challenges through clinical trials and global experiences, with a specific emphasis on Turkiye's public health context.

This study aimed to compare the short-term effects of sciatic nerve neural sliding and neural stretching exercises on hamstring muscle length and functional flexibility in wrestlers. The study participants included 74 wrestlers. The athletes were randomly divided into two groups: neural sliding and neural stretching groups. The hamstring flexibility and the functional flexibility were assessed using the active knee extension limitation (AKEL) angle and the sit and reach (SR) test one day before and immediately after the neural mobilization exercises, respectively. A three-way repeated measures analysis of variance was conducted that examined the effect of mobilization type, time, and gender on interest in AKEL right leg, AKEL left leg, and SR test. There is not a significant difference between the effect of two different mobilizations on AKEL right and left leg, and SR test ( P >0.05). It was determined there is statistically significant differences between premobilization and post-mobilization outcome measures for AKEL right leg ( F =59.886, P =0.001), AKEL left leg ( F =31.896, P =0.001), and SR test ( F =22.630, P =0.001). There is not a statistically significant difference between males and females by these three measures neural sliding and neural stretching exercises to the sciatic nerve in wrestlers were effective in increasing hamstring flexibility and functional flexibility and not superior to each other., Competing Interests: CONFLICT OF INTEREST No potential conflict of interest relevant to this article was reported., (Copyright © 2020 Korean Society of Exercise Rehabilitation.)

Background: The aim of this paper was to evaluate demographic and prognostic features of febrile seizures (FSs) in a tertiary center in Turkey., Methods: A retrospective study of 632 children with FS was conducted from January 1995 to January 2002 in the pediatric neurology and general pediatrics departments of Istanbul University, Istanbul Medical School. Patients data was collected and eligible patients were included in the study., Results: There were 386 male (61.1%) and 246 female (38.9%) patients, with a male-to-female ratio of 1.57. Twenty six (4.1%) patients had prenatal, 104 (16.5%) patients had perinatal-neonatal problems. Age at first seizure was 3-72 months with an average of 20.1 months. While 193 patients (30%) were admitted with two seizures, 246 (39%) were admitted with three or more. Out of 632 patients, 501 (79.2%) had recurrences. In an average of 5.8 years (4-8.8), 30 out of 632 patients (4.7%) were diagnosed with epilepsy. First degree relative with FS, age at first FS less than 18 months, height of peak temperature (<38.5 °C), less than 1 or 3 hours between onset of fever and seizure, complex first seizure, complex FS were all related to febrile seizure recurrence in a statistically significant way. Some risk factors for subsequent epilepsy development included complex FS and less than one hour of fever before FS. No patient with FS had died., Conclusions: Complex FS and less than 1 hour of fever before FS are common risk factors for both epilepsy and FS recurrence.

Background/aim: Anthrax is a zoonotic infection caused by Bacillus anthracis. We aimed to retrospectively evaluate cutaneous anthrax cases that occurred during an outbreak in eastern Turkey (Hakkari-Yüksekova), where people mostly earn their living from animal husbandry., Materials and Methods: Forty-six cutaneous anthrax patients that were admitted to the hospital during a very short duration of 3 months (June-August 2011) were evaluated., Results: Out of 46 patients, 27 (52%) were women and 19 (48%) were men. The mean age was 37 ± 13 years. The distribution of occupations was 1 butcher, 1 cook, 5 farmers, 27 housewives, 11 shepherds, and 1 teacher. Multiple lesions were seen in 7 patients (15%) and the rest of the patients had only 1 lesion. We observed significant clinical differences among the cases and noted which particular symptoms were associated with the various skin lesions. We treated our patients with intramuscular procaine penicillin or oral ciprofloxacin/doxycycline., Conclusion: Anthrax is an important health problem that can cause lethal outbreaks. Therefore, one should think about anthrax when faced with a patient with history of animal contact that has a painless ulcer with edema and/or vesicles, especially in endemic countries like Turkey.

Objective: Mild bleeding symptoms are commonly seen in the general population. The aim of this study was to determine the final clinical and laboratory features of children referred for a first evaluation with a suspected bleeding disorder in the pediatric outpatient clinic of İstanbul University., Materials and Methods: The medical records of 26,737 outpatients who were admitted to the Division of Ambulatory Pediatrics between 31 October 2011 and 31 October 2012 were evaluated retrospectively. Ninety-nine patients were initially diagnosed as having probable bleeding disorders and were followed up. The symptoms of bleeding in addition to coagulation tests were analyzed., Results: Of the 99 patients, 52 (52.5%) were male and 47 were female, and the mean age of the entire study group was 9.1±4.1 years (minimum-maximum: 2-18 years). Major bleeding symptoms were epistaxis in 36 patients (36.4%), easy bruising in 32 (32.3%), and menorrhagia in 6 (6.1%). After initial tests ordered by the pediatrician, 36 of 99 patients (36.4%) were diagnosed as having bleeding disorders that included von Willebrand disease in 12 (12.1%), hemophilia A or B in 9 (9.1%), and other rare factor deficiencies in 9 (9.1%). Six patients (6.1%) were found to have combined deficiencies. Seven of 36 patients had a family history of bleeding., Conclusion: Among the patients referred for bleeding disorders, 36.4% were diagnosed with a bleeding disorder with the help of primary screening tests ordered in the outpatient clinic.

Objective: The aim of this study was to evaluate the girls referred to the pediatric outpatient clinic with a presumptive diagnosis of early puberty due to early onset of breast development or pubarche., Methods: Within the study period, we evaluated 289 subjects referred for concerns about early onset of puberty. History, anthropometric data, bone age (BA), hormones including luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, and dehydroepiandrosterone sulfate, as well as pelvic ultrasonography (USG)-derived ovarian and uterine volumes were analyzed., Results: Of the 289 girls referred for early onset of pubertal development, 64 (22.1%) had false alarms for puberty. Of the remaining 225 girls, 41 (18.2%) were diagnosed as premature pubarche, 56 (24.9%) as premature thelarche (PT), and 128 (56.9%) as precocious puberty (PP). Girls with early-onset puberty had more advanced BA, greater uterine and ovarian volumes, and also higher LH values than subjects with PP and PT. Nearly half of these girls were 7-8 years of age. Body mass index (BMI) standard deviation score was significantly higher in the PP cases., Conclusions: There is a need for primary care physicians to be more knowledgeable on puberty and on puberty problems. There seems to be a preponderance of PP in 7-8-year-old children . Increased BMI may have a role in the trend towards earlier onset of puberty.

Objectives: The objective of this study was to determine the evidence-based performance of the pediatric emergency unit in the diagnosis of and treatment approach to the patients with asthma, bronchiolitis, and croup., Methods: In this study conducted in a retrospective cross-sectional way, emergency cards and computer data have been used. In the performance evaluation, the National Hospital Ambulatory Medical Care Survey criteria were considered. In the evaluation of performance in diagnosis, the rates of chest x-ray studies and use of corticosteroids and antibiotics were examined. Use of antibiotics in the cases not having a fever or any symptoms of bacterial infection and failure in prescribing steroids to the cases with moderate-to-severe symptoms were considered as bad performance criteria. χ(2) test was used for the data, which can be classified; Mann-Whitney U and Student t tests were used for the data with normal distribution and for the continuous variables., Results: Study groups were composed of 2795 patients (1742 cases with asthma, 115 cases with croup, 938 cases with bronchiolitis) aged between 3 and 140 months (mean [SD], 41.2 [31] months). Chest x-ray study was requested significantly more often in the cases of bronchiolitis and croup with severe symptoms. In asthma cases, chest x-ray study was requested in those with severe clinical symptoms. In all 3 groups, a significant difference between the severity levels of the cases, from whom hemogram was requested, was determined. Biochemical tests were requested more often in those with severe bronchiolitis or asthma. Antibiotics were prescribed to none of the mild bronchiolitis cases. However, steroids were recommended more often to patients with moderate and severe bronchiolitis. They were administered to all patients with croup. Systemic steroids were prescribed more often to those with moderate or severe asthma., Conclusions: In our unit, both antibiotics administration and chest x-ray studies requested in patients with bronchiolitis, croup, and asthma were in low rates. Steroids in asthma attacks were found to be high in severe cases and in croup cases as well.
