The effect of treatment with montelukast on levels of serum interleukin-10, eosinophil cationic protein, blood eosinophil counts, and clinical parameters in children with asthma.

Interleukin (IL)-10 is an important immunoregulatory and anti-inflammatory cytokine. IL-10 levels are reduced in asthmatic airways. A regulatory mechanism involving IL-4 induced allergen-specific IL-10 production may be defective in allergic subjects, and this defect potentially contributes to more intense inflammation.

The effect of montelukast on soluble interleukin-2 receptor and tumor necrosis factor alpha in pediatric asthma.

Proinflammatory cytokines such as tumor necrosis factor (TNF) alpha and soluble interleukin 2 receptor (sIL-2R) are very important mediators in induction of inflammatory response in lung. The aim of this study was to investigate anti-inflammatory response of cysteinyl leukotriene receptor antagonist montelukast on macrophage and T-cell activation by sIL-2R and TNF-alpha in mild atopic asthmatic children. Fifteen children with mild-to-moderate atopic asthma and 15 nonatopic children as control, enrolled in the study.

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.

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.

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.

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.

The Ala-9Val polymorphism in the mitochondrial targeting sequence (MTS) of the manganese superoxide dismutase gene is not associated with juvenile-onset asthma.

Background: We aimed to investigate the possible association between Mn-SOD polymorphism in the mitochondrial targeting sequence and asthma.

Methods: Alanine or valine polymorphism in the signal peptide of Mn-SOD gene was evaluated using a primer pair to amplify a 107-bp fragment followed by digestion with NgoM IV.

Results: No significant difference in genotype frequencies was found between patients and controls.

Craniofacial differences according to AHI scores of children with obstructive sleep apnoea syndrome: cephalometric study in 39 patients.

Background: Cephalometry is useful as a screening test for anatomical abnormalities in patients with obstructive sleep apnoea syndrome (OSAS).

Objective: To evaluate comprehensively the cephalometric features of children with OSAS, with or without adenotonsillar hypertrophy, and to elucidate the relationship between cephalometric variables and apnoea-hypopnoea index (AHI) severity.

Materials And Methods: The study population consisted of 39 children, aged 4-12 years, with OSAS.

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.

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.

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.
