Investigation of human colostrum Helicobacter pylori IgA content in lactating women.
OBJECTIVE: The objective was to investigate the colostral H. pylori-specific IgA content in a sample of the female population in Turkey where a high endemicity for H. pylori has always been reported. MATERIALS AND METHODS: One hundred and sixty-one pregnant women with positive serum H. pylori IgG antibody at the time of the last trimester were enrolled into the study. During the initial postpartum 24h, we obtained colostrum samples from each mother to test the presence and concentration of H. pylori-specific IgA. Breast milk antibody concentrations of H. pylori were measured by commercial ELISA tests. Sample absorbance/cut-off absorbance (s/c) ratio was used for semiquantitative interpretation. Ratios >1.1 were considered positive, ratios < or =1.1 negative. The statistical significance was tested by the Mann-Whitney U-test, and p < 0.05 was regarded as statistically significant. RESULTS: At least 2 ml of colostrum was obtained and analyzed (mean volume 2.5+/-0.45 ml). The results indicated the absence of H. pylori-specific IgA in 64 colostral samples (39.8%). However, the rest of the women (n = 97; 60.2%) had a mean H. pylori-specific IgA s/c ratio of 4.31+/-2.51 (range 1.2-10.3) in their colostral milk samples. The mean gestational age at the time of delivery was 38 weeks and 5 days, and the mean birth weight was 3, 224+/-433 g (range 4, 300-1, 940 g). Gestational age at birth and mode of delivery were not correlated with the colostral-specific IgA levels. CONCLUSIONS: Most of the lactating women (60.2%), who were seropositive for H. pylori, had some IgA in their colostral milk. Colostral milk theoretically can decrease H. pylori and perhaps many other enteric infections, whether or not it contains H. pylori-specific IgA. Therefore, breastfeeding is of utmost importance for neonates and should be encouraged. The H. pylori-specific IgA antibody concentration of colostral milk should be investigated in large-scale prospective studies for its effectiveness in the protection against neonatal transmission of this infection.

Prevalence of obstructive sleep apnea syndrome and associated symptoms in 3--11-year-old Turkish children.
Our objective was to investigate the prevalence of sleep-disordered breathing (SDB) and obstructive sleep apnea syndrome (OSAS) in 3-11-year-old Turkish children. A cross-sectional study was conducted in Zonguldak, northwestern Turkey. Symptomatic children were identified by using a self-administered questionnaire and were classified into three groups: nonsnorers, occasional snorers, and habitual snorers. All habitual snoring children were invited to undergo polysomnography (PSG). Nine hundred fifty-four children (79.5%) were nonsnorers, 205 (17.2%) were occasional snorers, and 39 (3.3%) were habitual snorers. There was no significant relationship between gender and habitual snoring (male, 3.4%; female, 3.1%; P > 0.05; odds ratio (OR), 1.13; 95% confidence interval (CI), 0.59-2.14). There was a statistically significant relationship between habitual snoring and allergic rhinitis (OR, 4.23; 95% CI, 2.14-8.35). Four children who snored every night, and who had apnea spells and/or troubled sleep, underwent adenoidectomy and/or tonsillectomy before polysomnographic evaluation because of clinical detoriation. Twenty-eight of 39 children with habitual snoring participated in PSG evaluation. PSG revealed that 11 children (0.9% of the total population) had OSAS. When 4 operated children were added to these 28 children, we found the minimum prevalence of OSAS to be 1.3% in our study group. There was a significant correlation between OSAS and troubled sleeping (P <0.001; OR, 4.37; 95% CI, 1.33-14.3). We found the prevalence of habitual snoring to be 3.3% in Turkish children by using self-administered questionnaires. Allergic rhinitis was significantly correlated with habitual snoring. Minimum estimated prevalence of OSAS was found to be 1.3%.

Metaphyseal enchondrodysplasia with 2-hydroxy-glutaric aciduria: observation of a third case and further delineation.
In the course of evaluating a 17 months old boy with waddling gait and swollen joints, we found generalized, severe ossification defects in the metaphyses of his long bones. The differential diagnosis included nutritional or genetic rickets, metaphyseal dysplasia, and enchondrodysplasia. Calcium, phosphate and alkaline phosphatase were normal, while targeted analysis of urinary organic acids repeatedly revealed excretion of 2-hydroxy-glutaric acid. Thus, this child appears to have an unusual combination of findings described in just two other patients so far, a girl and a boy, and called 'spondyloenchondrodysplasia with D-2-hydroxy-glutaric aciduria'. These three cases are similar in terms of severe metaphyseal lesions, mild vertebral involvement, and presence of 2-hydroxy-glutaric acid in the urine. We consider this a radiographically and biochemically distinct entity, for which we suggest the name of 'metaphyseal enchondrodysplasia with 2-hydroxy-glutaric aciduria'.

Midline cleft of the lower lip associated with Robinow syndrome.
Robinow syndrome (also named "fetal face syndrome") includes a series of anomalies including mesomelic brachymelia, bifid terminal phalanges of the hands and feet, abnormalities of vertebrae and ribs, and hypoplastic external genitalia. A midline cleft of the lower lip and mandible is an extremely rare maxillofacial deformity. Seventy cases have so far been described to our knowledge. We report a patient with Robinow syndrome and midline cleft of the lower lip and mandible and describe the reconstruction of these anomalies. We propose that this anomaly should be added to the range of malformations associated with the syndrome.

Gallbladder and urinary tract precipitations associated with ceftriaxone therapy in children: a prospective study.
The incidence and outcome of gallbladder and urinary tract complications in children receiving ceftriaxone therapy were evaluated prospectively. The subjects were given intravenous ceftriaxone, 100 mg/kg/day, in two divided doses infused over 20-30-minute periods, for 5-14 days. Serial abdominal ultrasonography revealed gallbladder and urinary tract precipitations in five of 35 children, three of whom had gallbladder pseudolithiasis, one gallbladder sludge and one gallbladder pseudolithiasis and urinary bladder sludge. The children who had gallbladder sludge and gallbladder pseudolithiasis with urinary bladder sludge had abdominal pain, nausea and vomiting. Three children remained symptom-free. The gallbladder precipitations were found after 4-9 days of ceftriaxone therapy, and resolved completely 7-19 days after the end of treatment. The urinary tract precipitation was found on the 5th day after cessation of ceftriaxone therapy and resolved 7 days later. Ceftriaxone-associated gallbladder pseudolithiasis, gallbladder sludge and urinary bladder sludge usually resolve spontaneously and physicians should be aware of these complications so as to avoid unnecessary therapeutic procedures.

Effect of iodine supplementation on goiter prevalence among the pediatric population in a severely iodine deficient area.
We evaluated goiter status and urinary iodine excretion (UIC) of 304 school-children (7-12 years old) 3 years after a law was passed for mandatory production of iodinated salt in an area previously characterized by severe iodine deficiency in Zonguldak, a mountainous city in the West Black Sea region in Turkey. We examined all the children for goiter by palpation, measured sonographic thyroid volumes (STV) and UIC. Eighty-two percent of families had been using iodinated salt. UIC was above 100 microg/l in 71.2% of the children and median UIC was sufficient (143.5 microg/l). The prevalence of goiter was lower at ultrasound (14.6%) than by palpation (19.4%). Median STV values were within recommended normal limits at all ages. Although Zonguldak had been a highly endemic region, it became mildly endemic 3 years after mandatory iodination of salt, with decrease of goiter prevalence.

Isovaleric acidaemia: cranial CT and MRI findings.
Isovaleric acidaemia is an inborn error of leucine metabolism due to deficiency of isovaleryl-CoA dehydrogenase, which results in accumulation of isovaleric acid in body fluids. There are acute and chronic-intermittent forms of the disease. We present the cranial CT and MRI findings of a 19-month-old girl with the chronic-intermittent form of isovaleric acidaemia. She presented with severe metabolic acidosis, hyperglycaemia, glycosuria, ketonuria and acute encephalopathy. Cranial CT revealed bilateral hypodensity of the globi pallidi. MRI showed signal changes in the globi pallidi and corticospinal tracts of the mesencephalon, which were hypointense on T1-weighted and hyperintense on T2-weighted images.

Effects of inhaled corticosteroids on growth in asthmatic children: a comparison of fluticasone propionate with budesonide.
In asthmatic children inhaled corticosteroids are widely used. However, there are some concerns about the systemic adverse effects of these drugs, especially in the growing child. We performed this prospective study in order to compare the effects of 400 microg/day of budesonide (BUD) and 250 microg/day of fluticasone propionate (FP) on growth in prepubertal (aged 4-11.5 years), moderate persisting asthmatic children. One hundred patients (51 boys and 49 girls), who were randomized into two groups, were recruited for the study. The first group was treated with BUD, 2X 200 microg/day, and the second group was treated with FP, 2X 125 microg/day, by using a medium-size volume-spacer metered-dose inhaler. Growth in children with asthma who were treated by inhaled corticosteroids was calculated by growth velocity over a 12-month period. Comparisons between treatment groups were calculated by t-test and chi-square test. There were no significant differences between BUD and FP groups for sex, age, first height, and growth velocity. Moderate persisting, prepubertal asthmatic children treated with 250 microg/day of FP appeared to have no different linear growth than those children who received 400 microg/day of BUD.

Prevalence and risk factors for childhood asthma in Zonguldak, Turkey.
Prevalence of asthma and other allergic diseases varies between different regions throughout the world. The aim of this study was to determine the prevalence of asthma and allergies and some risk factors for asthma in schoolchildren, aged between 6 and 16 years old, in Zonguldak, Turkey. We prepared 1500 questionnaires according to the International Study of Asthma and Allergies in Childhood criteria and distributed them in schools, to be completed at home by parents. Appropriately completed 1349 questionnaires, including complementary questions for risk factors, were taken into consideration. Data for air-pollutant levels of sulfurdioxide (SO2) and total suspended particles were obtained also. The prevalence of current wheezing symptoms was 9.6% in children aged between 13 and 16 years old and 11.2% in the total sample. In terms of physician-diagnosed asthma, allergic rhinitis, and eczema, the prevalences were 4.9, 37.7, and 13.2%, respectively. A family history of allergy, diagnosis, or symptoms of allergic rhinitis and bronchitis (age range, 6-9 years) and male gender were found to be significant predictors for asthma symptoms with adjusted odds ratios of 2.089, 0.336, 4.707, 1.652, and 0.599, respectively. Strongly positive correlation between number of symptomatic asthmatic patients and air pollution levels for SO2 (r = 0.864; p = 0.001) and total suspended particles (r = 0.891; p = 0.001) were observed also. The prevalence of asthma is high in Zonguldak, Turkey, and there is a strong correlation between air pollution and asthma symptoms. Allergy in the first-degree relatives, diagnosis of bronchitis and allergic rhinitis, age, and male gender are more important than the other factors in predicting asthma.
