Pathogens in Pediatric Septic Arthritis: A Multi-Center Study in Turkiye (PEDSART Study).

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.

Factors in Vaccine Refusal by Patients Applying for COVID-19 PCR Test.

Objective: This study was designed to determine the reasons for vaccine rejection in patients who applied for the coronavirus disease-2019 (COVID-19) polymerase chain reaction (PCR) test but did not receive the vaccine. Methods: The study was conducted prospectively in the emergency department of a tertiary hospital between 31.01.2022 and 31.05.2022. 1000 patients who applied for the COVID-19 PCR test and refused to be vaccinated were included. The COVID-19 status of the participants, reasons for their application, number of PCR tests, methods of obtaining information about the vaccine, and reasons for the rejection of the vaccine were questioned. Results: 54.6% of the participants were male and 45.4% were female. 60.7% of the patients applied for testing due to symptoms, 25.4% due to contact with people with symptoms, and 23.9% due to travel. 43.3% of the cases had COVID-19 infection; 53.6% of them had tested an average of 2-5 times in the last year. Most of the information about the vaccine was taken from social media, television, medical publications, and people around, respectively. Of the participants, 62.0% believed that COVID-19 vaccines had side effects, 47.3% believed that it had no protection, and 30.9% believed that there was not enough study on the subject. As the age grew, the rate of learning information from social media increased. Conclusions: The most common reasons for COVID-19 vaccine rejection were vaccine side effects, doubtful vaccine protection, and concerns about the lack of sufficient studies on the vaccine. The higher the education level, the higher the vaccine rejection rate.

Evaluation of factors affecting the length of stay of geriatric patients in the emergency department.

OBJECTIVE: The emergency department length of stay (EDLOS) is one of the essential parameters of emergency healthcare management efficacy, and prominent factors that contribute to EDLOS are critical in enhancing emergency department (ED) patient care effectiveness, particularly for older patients, which is rarely investigated. METHODS: This single-center, prospective cohort study was performed in the ED of a tertiary care hospital. The patients were classified into two groups according to EDLOS (≥4 h vs. <4 h). The chief complaints, consultant branches, the patients' comorbidities, polypharmacy status, time of presentation, laboratory, imaging investigations, EDLOS, Clinical Frailty Score (CFS) score, mini mental examination test, National Early Warning Score 2 (NEWS2), consultations, and outcome of the patients were compared with Spearman and Kendall tau-b correlations. RESULTS: During the 30-day study period, a total of 222 geriatric patients were included in the study. The mean age of study patients was 79.13±9.43 years, and 47.05% of patients were male. The Median EDLOS was 250 (range, 60-1440) min. The patients who arrived on the night shift (p=0.047), who had chronic heart failure (p=0.025), chronic obstructive pulmonary disease (p=0.03), severe dementia according to the MMSE (p=0.008), higher CFS frailty scores (p=0.03), and higher clinical acuity according to the NEWS2 score, were found to be positively correlated to an EDLOS of >4 h. (p=0.001) Any specialty consultation and specialty consultation number, along with hospitalization, were also positively correlated to an EDLOS of >4 h. (p=0.001). CONCLUSION: High-acuity patients with frailty and dementia are at increased risk for increased EDLOS via consultations. Emergency and consultation physicians should communicate better about which patients are vulnerable to EDLOS case by case, and the patient outcome must be decided as soon as possible.

Vitamin D status in pubertal children.

BACKGROUND: Optimal vitamin D status has a great importance in puberty, which is a period of peak bone mineral acquisition. In this study, we aimed to assess the effect of pubertal period on vitamin D status. METHODS: The study included totally 200 healthy children, aged between 4 and 14 years. Group 1 included 100 prepubertal, children, aged between 4 and 8 years. Group 2 included 100 pubertal children, aged between 9 and 14 years. They had no chronic illnesses. Ages, heights, weights, genders, Body Mass Indexes (BMIs), socioeconomic and educational status of families were established. Serum 25-hydroxyvitamin D (25(OH)D) levels were measured by high performance liquid chromatography (HPLC). Serum parathyroid hormone (PTH) was evaluated using an immunoradiometric assay kit. Serum calcium (Ca), phosphorus (P) and alkaline phosphatase (ALP) levels were measured. RESULTS: We determined that 25(OH)D levels were lower with higher PTH levels in the group aged 9 to 14 years (pubertal children), compared to the group aged 4 to 8 (prepubertal children). Gender, weight, height or BMI, family socioeconomic and education status did not affect serum 25(OH)D levels of children in each group. CONCLUSIONS: We demonstrated that vitamin D deficiency was more commonly seen in the pubertal children, compared to pre pubertal period. Children should be supported with vitamin D supplements during the puberty, which has a great importance for rapid increase in bone mass.

Management of chronic cervical lymphadenopathy in children.

BACKGROUND: It is important how to evaluate chronic cervical lymphadenopathies and when to perform excisional biopsy in children. We tried to analyze the usefulness of clinical and ultrasonographic findings in order to differentiate malign lymphadenopathies from benign ones. METHODS: This prospective study included 100 children who had cervical lymphadenopathies, larger than 1. 5 cm for 4 weeks duration at least. Children were between 2 and 14 years old, the mean age was 6.88±3.38 years. They were examined by clinical symptoms and ultrasonographic appearances. Persistent lymphadenopathies were evaluated by excisional biopsy. RESULTS: Cervical lymhadenopathies of 80 children with well clinical symptoms decreased and resolved within 10 weeks durations. Their ultrasonographic findings revealed regular margins, ovoid shapes and getting smaller than 1. 5 cm. The remaining 20 children persisting longer than 10 weeks at the same size, with worrisome clinical symptoms and susceptible ultrasonographic findings (round shapes, irregular margins) underwent excisional biopsy. According to the biopsy results, five had tubercular lymphadenopathies, three had Hodgkin'slenfoma, two had acute lymphoblastic leukemia. CONCLUSIONS: Chronic cervical lymphadenopathies can persist up to 10 weeks, althoughthey are reactive and benign.

Evaluation of antibiotic use among hospitalised patients in a paediatric department of a training hospital in Turkey.

BACKGROUND: Antibiotics are widely used and inaccurate or inappropriate prescription of antibiotics causes a significant increase in the prevalence of multidrug-resistant bacterial infections among children. This research aimed to study antibiotic prescriptions in hospitalised paediatric patients and to determine the prevalence of inappropriate antimicrobial use and the main types of prescribing errors. METHODS: After obtaining the Ethics Committee approval, screening was conducted among 535 patients admitted to the Department of Pediatrics at Haydarpasa Numune Training and Research Hospital in the period from 01 January 2016 to 31 December 2016 who had been treated with an antibiotic. Patients' demographics, diagnosis and antibiotic therapy details were collected using a standardised case report form and assessed by a clinical pharmacologist and an infectious disease specialist regarding the convenience and accurateness of prescription of antibiotics. RESULTS: Out of 535 antibiotic prescriptions, single antibiotics were used inappropriately in 216 (56.10%) of the patients and there were 39 (26%) unnecessary antibiotic combinations. Most of the errors were made in the dose frequency (55.69%), followed by indication (25.88%), administration route (16.08%) and dosage (2.67%). CONCLUSIONS: The results of our study show that a high level of antibiotics in the paediatric clinic was misprescribed. Inappropriate usage increases the chances of microbial resistance and the cost of treatment. Precautions should be taken in this regard.

The evaluation of vitamin K status in children with febrile seizure.

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.

Evaluation of potential drug-drug interactions in a pediatric population.

AIM: A large number of medications are prescribed in pediatric clinics and this leads to the development of drug-drug interactions (DDI) that may complicate the course of the disease. The aim of the study was to identify the prevalence of potential drug-drug interactions, to categorize main drug classes involved in severe drug-drug interactions and to highlight clinically relevant DDIs in a pediatric population. MATERIAL AND METHODS: A total of 1500 prescriptions during the 12-month study period were retrospectively reviewed; 510 prescriptions that comprised two or more drugs were included in study. The presence of potential drug-drug interactions was identified by using the Lexi-Interact database and categorized according to severity A (unknown), B (minor), C (moderate), D (major), and X (contraindicated). RESULTS: There were 1498 drugs in 510 prescriptions; 253 of these (49.6%) included 2 drugs, 228 (44.7%) included 3-4 drugs, and 29 (5.6%) included ≥5 drugs. A total of 634 (42%) potential drug-drug interactions were idenfied. Among those, 271 (42.7%) were categorized as A, 284 (44.8%) as B, 53 (8.4%) as C, and 26 (4.1%) as D. There was no potential risk for X interaction. Anti-infectives (36%) were the most commonly prescribed drug classes involved in C and/or D categories. Clarithromycin was the most commonly interacting agent that interfered with budesonide. CONCLUSION: It is noteworthy that a significant number of drugs causing potential drug-drug interactions are prescribed together in pediatric clinics. Increasing the awareness of physicians on this issue will prevent potential complications and ensure patient safety.

Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study).

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.

Topical sucralfate cream treatment for aplasia cutis congenita with dystrophic epidermolysis bullosa: a case study.

Bart syndrome consists of aplasia cutis congenita (ACC) and dominant or recessive dystrophic epidermolysis bullosa (DEB), associated with skin fragility and nail dysplasia. ACC in DEB is thought to be caused by trauma, the most cited cause being in utero formation of bullae consequent to friction of the limbs. Epidermolysis bullosa (EB) refers to a hereditary mechanobullous disease following trauma, characterised by formation of blisters on the skin and mucous membranes. There are four categories of the disease, including epidermolysis bullosa simplex, junctional epidermolysis bullosa, dystrophic epidermolysis bullosa and Kindler syndrome. Infection, sepsis and death may occur as a consequence of generalised blistering with complication. We present the case of a newborn diagnosed with DEB and whose lesions became almost fully epithelialised after treatment with 10% topical sucralfate.

Immunomodulator effect of topical zinc oxide application in tuberculin skin test.

OBJECTIVE: We aimed to evaluate the sensitivity of tuberculin skintest (purified protein derivative-PPD) by topical zinc application on test site to improve diagnostic reliability. METHODS: We performed this study in 100 children aged 6-14 years, and plasma zinc levels were analyzed after 10-12 hours fasting. After PPD, we applied 40% zinc oxide cream on one forearm and placebo on the other forearm. PPD indurations were measured 72 hours later. RESULTS: In this study, 26% of the children showed increases in PPD induration following local zinc applications. There was no correlation between indurations size and serum zinc levels. CONCLUSION: We concluded that topical zinc cream application can enhance sensitivity of tuberculin reactivityin the diagnosis of tuberculosis.

Carotid intima media thickness in obese children: is there an association with hyperlipidemia?

BACKGROUND: We aimed to evaluate the association between hyperlipidemia and carotid intima media thickness in obese children, compared to non-obese ones. METHODS: Two hundred (110 girls, 90 boys) children aged between 6 and 15 years participated in this study. The obese group included 53 girls, 47 boys whose body mass indices (BMI) above 95th percentile, the control group included 57 girls, 43 boys who had normal weight. Fasting total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) levels were measured. Carotid intima media thickness (cIMT) was performed with neck ultrasound. RESULTS: The median thickness of right, left and mean carotis intima media were statistically higher in the study group, compared to the control group. The mean cholesterol, triglyceride, HDL-C, LDL-C levels of the study group were statistically higher, compared to the control group. There was no relationship between BMI and left carotis intima media thickness, but there was statistically significant relationship between BMI and right, mean cIMTs in the study group. There was no correlation between serum lipid levels and cIMTs in the study group. The mean atherogenic index of the study group was statistically higher, compared to the control group. There was no statistical correlation between atherogenic index and cIMTs in both of the groups. CONCLUSIONS: We observed that obese children had higher carotis intima media thicknesses. Carotis intima media thickness related to obesity can play an important role in future pre-atherosclerotic changes. Large population based studies are required to confirm this associaton.

Evaluation of in utero sensitization by screening antigen-specific immunoglobulin E levels in umbilical cord blood.

INTRODUCTION: The incidence of asthma and atopic reactions is increasing worldwide. Previous reports have suggested that maternal exposure to allergens during pregnancy may have potential effects on allergic sensitization in infants. AIM: To evaluate the effects of maternal exposure to environmental allergens during pregnancy on in-utero sensitization. MATERIAL AND METHODS: Two hundred mothers and their infants were analyzed in this cross-sectional study. Mothers were given a questionnaire that had a series of questions to evaluate the maternal allergic status and environmental exposures during pregnancy. Plasma specific immunoglobulin E (IgE) levels to pets, grass, food (nuts) of all mothers and their infants were analyzed by an immune-enzymatic assay. RESULTS: There was no significant correlation between plasma specific IgE positivity in mothers, with regard to keeping indoor domestic pets, living in grass habitat, eating nuts in diet. A significant correlation was found between specific IgE presence in mothers and allergic reactions; however, there was no correlation between plasma specific IgE positivity of mothers and infants. CONCLUSIONS: We concluded that prenatal maternal sensitivity to environmental allergens could not be evaluated as a predictive factor for in-utero sensitization.

Detection of upper limit of normal values of anti-DNase B antibody in children's age groups who were admitted to hospital with noninfectious reasons.

OBJECTIVE: Anti-streptolysin O (ASO) and anti-DNase B (ADB) titers are used for the diagnosis of poststreptococcal complications. Ranges of normal values of ASO and ADB titers vary, depending on age, population and different time intervals. Although many studies have been performed for determination of the ASO titer in our country, only a few studies have been conducted for specification the upper limit of normal for (ULN) ADB. In our study we aimed to determine the upper limit of normal of ADB antibody titers in children aged 5-15. METHODS: One hundred and twenty one children aged from 5-15 who were admitted to our outpatient clinic of Haydarpasa Numune Training and Research Hospital with noninfectious reasons between November 2013 and March 2014 were included in the study. Patients who met the following criteria were included in the study; absence of streptococcal infection in the last three months in physical examination and/or no growth of group A, C, and G of beta-haemolytic streptococci in throat culture, normal ranges of ASO and C reactive protein (CRP) levels. All serum samples were analyzed collectively by nephelometric method. The upper limit of normal value for anti-DNase B has been defined by separating the upper 20% from the lower 80% of all measurements. RESULTS: Anti-DNase B antibody levels were ranged between 50-576 IU/ml and its upper limit was 219.2 IU/ml. When analyzed according to age groups, anti-DNase B antibody levels in the group aged between 5-10, ranged between 50-576 IU/ml and its upper limit was 212.2 IU/ml, anti-DNase B antibody levels in the group aged 10-15, ranged between 50-408 IU/ml and its upper limit was 231.2 IU/ml (p=0.008). CONCLUSION: Based on our results, upper normal values ADB antibody showed variations with age in our results. Therefore national reference values should be detected by more comprehensive studies.

Association of glycosylated hemoglobin (HbA1c) levels with Iinsulin resistance in obese children.

OBJECTIVES: We investigated the relationship between insulin resistance reflected by homeostasis model assessment (HOMA-IR) index and serum HbA1c levels of obese children. MATERIAL AND METHODS: This study included 70 obese and 60 normal weight healthy children between the ages of 3 and 15. Anthropometric measures and biochemical tests (fasting glucose, fasting insulin, HbA1c) were performed on all subjects. Plasma glucose levels were measured by the glucose oxidase method. Plasma insulin concentrations were measured by radioimmunoassay (RIA). HOMA-IR index was used to estimate insulin resistance. A cut-off HOMA-IR level of ≥2.5 was accepted. The HbA1c analysis was performed using high-pressure liquid chromatography. The statistical analysis was performed using SPSS 5. Student's unpaired t-test and the Mann-Whitney U test were used to determine statistical significance. RESULTS: Gender distribution did not reveal significant difference among the obese (F: 48.6%, M: 51.4%) and the non-obese (F: 46.7%, M: 53.3%) groups. The mean age value was significantly higher in the obese group (10.09 ± 3.09) (p > 0.005) than the non-obese group (8.31 ± 3.14) (p < 0.05). The mean value of body mass index (BMI) was 25.55 ± 4.3 in the obese group and 16.63 ± 2.3 in the non-obese group. The mean HOMA-IR values of obese group (2.84 ± 1.77) was significantly higher than the non-obese group (1.50 ± 0.95) (p < 0.005). Insulin resistance was significantly higher in the obese group. Subjects with HOMA-IR ≥2.5 levels in the obese group had significantly higher HbA1c values than those with HOMA-IR <2.5 levels. CONCLUSIONS: High HbA1c levels in obese children can be used as a screening tool to detect insulin sensitivity and resistance at an early stage.

The GABAA receptor γ2 subunit (R43Q) mutation in febrile seizures.

BACKGROUND: Febrile seizure is the most common form of childhood seizure. Although its exact cause is unclear, many researchers emphasize the importance of its genetic predisposition. Recent genetic studies revealed the importance of the mutations of the gamma-aminobutyric acid A receptor as the etiology of the febrile seizures. R43Q mutation affecting the γ2-subunit N-terminal domain has been related to childhood absence epilepsy and febrile seizure. METHODS: We investigated R43Q mutations of the GABRG2 gene, located on the long arm of chromosome 5 encoding the γ2-subunit of the gamma-aminobutyric acid A receptor. We studied 44 patients with febrile seizure and 49 children without any febrile seizure who were admitted to our clinic. RESULTS: We found that 36% of our patient group, the children who experienced febrile convulsions, had heterozygous R43Q mutation. Statistical studies revealed that heterozygous R43Q mutation of gamma-aminobutyric acid A receptor γ2 subunit was higher in the study group than in the control group (P < 0.01). CONCLUSIONS: Heterozygous gamma-aminobutyric acid A receptor γ2 subunit (R43Q) mutation may have an effect in the development of febrile seizures.

Obesity and asymptomatic hypertension among children aged 6-13 years living in Bursa, Turkey.

INTRODUCTION: Hypertension is an independent risk factor for cardiovascular disease. It is known that essential hypertension begins at a very early age. Recently, there have been reports of an increase in childhood hypertension, which has been attributed to an increase in the prevalence of childhood obesity. Obesity-dependent or independent asymptomatic hypertension can only be determined by random blood pressure measurements in children. OBJECTIVE: In this study, we aimed to investigate the prevalence of obesity and asymptomatic hypertension among children living in Bursa, Turkey. METHODS: One thousand children living in Nilüfer district and being served by the Fethiye Bulvar Family Health Care Center were enrolled in this study. All seven family physicians working at the centre participated in the study. RESULTS: Eighty-five children (8.5%) were determined to be hypertensive. One hundred and twelve children (11.2%) were obese. Blood pressure and body mass index (BMI) increased with age, with peak prevalence of hypertension at age 12 and of obesity at age 10. CONCLUSIONS: The prevalence of obesity and hypertension is high among school-age children in Turkey. Family physicians should consistently perform blood pressure and BMI measurements as a part of well child visits through late childhood.

The epidemiology and economic impact of varicella-related hospitalizations in Turkey from 2008 to 2010: a nationwide survey during the pre-vaccine era (VARICOMP study).

Varicella can cause complications that are potentially serious and require hospitalization. Our current understanding of the causes and incidence of varicella-related hospitalization in Turkey is limited and sufficiently accurate epidemiological and economical information is lacking. The aim of this study was to estimate the annual incidence of varicella-related hospitalizations, describe the complications, and estimate the annual mortality and cost of varicella in children. VARICOMP is a multi-center study that was performed to provide epidemiological and economic data on hospitalization for varicella in children between 0 and 15 years of age from October 2008 to September 2010 in Turkey. According to medical records from 27 health care centers in 14 cities (representing 49.3% of the childhood population in Turkey), 824 children (73% previously healthy) were hospitalized for varicella over the 2-year period. Most cases occurred in the spring and early summer months. Most cases were in children under 5 years of age, and 29.5% were in children under 1 year of age. The estimated incidence of varicella-related hospitalization was 5.29-6.89 per 100,000 in all children between 0-15 years of age in Turkey, 21.7 to 28 per 100,000 children under 1 year of age, 9.8-13.8 per 100,000 children under 5 years of age, 3.96-6.52 per 100,000 children between 5 and 10 years of age and 0.42 to 0.71 per 100,000 children between 10 and 15 years of age. Among the 824 children, 212 (25.7%) were hospitalized because of primary varicella infection. The most common complications in children were secondary bacterial infection (23%), neurological (19.1%), and respiratory (17.5%) complications. Secondary bacterial infections (p < 0.001) and neurological complications (p < 0.001) were significantly more common in previously healthy children, whereas hematological complications (p < 0.001) were more commonly observed in children with underlying conditions. The median length of the hospital stay was 6 days, and it was longer in children with underlying conditions (<0.001). The median cost of hospitalization per patient was $338 and was significantly higher in children with underlying conditions (p < 0.001). The estimated direct annual cost (not including the loss of parental work time and school absence) of varicella-related hospitalization in children under the age of 15 years in Turkey was $856,190 to $1,407,006. According to our estimates, 882 to 1,450 children are hospitalized for varicella each year, reflecting a population-wide occurrence of 466-768 varicella cases per 100,000 children. In conclusion, this study confirms that varicella-related hospitalizations are not uncommon in children, and two thirds of these children are otherwise healthy. The annual cost of hospitalization for varicella reflects only a small part of the overall cost of this disease, as only a very few cases require hospital admission. The incidence of this disease was higher in children <1 year of age, and there are no prevention strategies for these children other than population-wide vaccination. Universal vaccination is therefore the only realistic option for the prevention of severe complications and deaths. The surveillance of varicella-associated complications is essential for monitoring of the impact of varicella immunization.

A retrospective analysis of adenoidal size in children with allergic rhinitis and nonallergic idiopathic rhinitis.

BACKGROUND: Increased incidence of adenoidal tissue enlargement in children with allergic rhinitis (AR) when compared to non-atopic children had been reported. However, data with respect to the comparison of adenoidal size in children with AR and non-allergic idiopathic rhinitis (IR) is still lacking in the literature. OBJECTIVE: We aimed to compare the size of the adenoid in children with AR and with nonallergic IR. METHODS: Adenoid/nasopharynx ratios (ANR) of all children were calculated in both AR and IR patients and the mean ratios were compared. RESULTS: There were 52 patients in the AR group and 56 patients in the nonallergic IR group. Demographic data were similar within the two groups. The mean ANR was 0.59 +/- 0.08 in AR group, whereas it was 0.77 +/- 0.12 in nonallergic IR group. The ANR was very significantly high in the nonallergic IR patients (p = 0.0001). CONCLUSION: Our results suggest that there could be a cellular immune deficiency in allergic children which effects the enlargement of the pharyngeal tonsils. This might be explained with the hypothesis that allergic patients have a deficiency in T-helper 1 cell activity and interferon-gamma production. Larger studies which compare the cytokine profiles of children with AR and with nonallergic IR, will clarify the role of recurrent respiratory infection which is a real problem in clinical practice with allergy.

Hemoglobin a1c levels in children with asthma using low dose inhaled corticosteroids.

OBJECTIVES: Steroids may raise the blood glucose levels as a systemic effect. Due to this, the potential effect of prophylactic use of inhaled steroids (ICS) on HbA1c levels in children with asthma was investigated. STUDY DESIGN: Case control study. ? SETTING: Outpatient department. PARTICIPANTS: 141 children with asthma but without diabetes (study group) and 52 children without diabetes or asthma (control group). MAIN OUTCOME MEASURE: HbA1c levels. RESULTS: The mean age of the study group (n=141) was 6.6?3.0 years and comprised 70 females (50% of the group) and 71 males. The mean age of the control group (n=52) was 7.1?3.0 years, and comprised 24 females (46%) and 28 males (54%). Age and sex differences between the groups were not significant. The mean HbA1c value was 5.44?0.75% among the children with asthma and 5.14?0.41% in the control group. HbA1c levels in children with asthma was significantly higher than the control group (P=0.006). No significant correlation was found between cumulative dose of ICS and HbA1c levels. Similarly, levels of HbA1c did not change with increased time of usage of ICS (P=0.96). CONCLUSION: Asthmatic children who are taking low doses of ICS have higher HbA1c values than healthy children.
