Vitamin D deficiency continues to be a worldwide problem, especially in developing countries. The aim of this study was to investigate potential risk factors for vitamin D deficiency. Girls (n = 89) aged 13 to 17 y were enrolled in the study. Study subjects were stratified into 3 groups: Group I included girls living in a suburban area; Group II girls lived in an urban area, and Group III girls lived in an urban area and wore concealing clothes for religious reasons. At the end of winter (in April) serum 25-hydroxyvitamin D [25(OH)D] levels were measured and dietary data were collected using questionnaires. Vitamin D deficiency was defined as a serum 25(OH)D concentration < 25 nmol/L, and insufficiency as a 25(OH)D concentration between 25 and 50 nmol/L. The lumbar and femur neck bone mineral densities (BMD) were measured using dual X-ray absorptiometry (DEXA). Overall, 39 girls (43.8%) had vitamin D insufficiency and 19 (21.3%) had vitamin D deficiency. In group III (wearing covered dress) the serum 25(OH)D concentrations (28.13 +/- 12.53 nmol/L) were significantly lower than in the other 2 groups, and within this group, 50% of girls were vitamin D deficient. The lumbar and femur neck BMD of girls with lower 25(OH)D levels did not differ from those with adequate vitamin D levels. We conclude that vitamin D deficiency is an important problem in Turkish adolescent girls, especially in those who follow a religious dress code; therefore, vitamin D supplementation appears to be necessary for adolescent girls.
The aim of this study is to describe the health status, health care received, and their impact on the quality of life in patients with hemophilia. Patients with severe factor VIII or IX deficiency without inhibitors or other chronic disease were enrolled. Turkish version of the Hemophilia-Specific Quality of Life Index (Haemo-QoL) questionnaire was administered to the pediatric patients aged 4 to 16 years and Haem-A-QoL to the adult patients. Joints were evaluated according to the World Federation of Hemophilia (WFH) orthopedic joint scores.Thirty-nine children/adolescents and 31 adult patients were enrolled. Mean Haemo-QoL scores were 39.6 +/- 15.0 for the children and mean Haem-A-QoL 47.4 +/- 14.1 for the adult patients, respectively. Internal consistency reliability was generally sufficient. Total Cronbach's alpha coefficient was >.70 (range .77-.96) in all the age groups. Mean total WFH orthopedic joint scores were 1.83 +/- 2.7, 4.9 +/- 4.96, and 6.94 +/- 6.15 in 4-7, 8-12, and 13-16-year-old groups, respectively. They were more impaired in the adult patients (16.23 +/-14.12). These results show that the Turkish version of the Haemo-QoL and Haem-A-QoL are reliable instruments to measure the quality of life in the pediatric and adult patients with severe hemophilia. When compared to the Haemo-QoL scores of an international multicenter West European study of children, quality of life in the Turkish patients were more impaired in the subscales of physical health, feeling, view, school and sport, and treatment as well as more impaired WFH joint scores. The authors recommend primary factor prophylaxis and encouraging the patients to learn home treatment to improve joint scores and quality of life.
We conducted this study to investigate the efficacy of the silicon gel application on the nares in prevention of nasal injury in preterm infants ventilated with nasal continuous positive airway pressure (NCPAP). Patients (n=179) were randomized into two groups: Group 1 (n=87) had no silicon gel applied to nares, and in Group 2 (n=92), the silicon gel sheeting was used on the surface of nares during ventilation with NCPAP. Nasal injury developed in 13 (14.9%) neonates in Group 1 and 4 (4.3%) newborns in Group 2 (OR:3.43; 95% CI: 1.1-10.1; P<0.05). The incidence of columella necrosis was also significantly higher in the Group 1 (OR: 6.34; 95% CI: 0.78-51.6; P<0.05). We conclude that the silicon gel application may reduce the incidence and the severity of nasal injury in preterm infants on nasal CPAP.
Objective:To evaluate the effect of domperidone use on corrected QT interval in premature infants.Study Design:A prospective study of premature infants receiving domperidone was included in this study. A baseline electrocardiogram was obtained just before and 3, 7 and 14 days after initiation of domperidone. Corrected QT was considered prolonged if it exceeded the upper limit for age.Result:A total of 40 premature infants were enrolled in this study. The mean birth weight of 1109±332 g, mean gestational age of 28.8±2.4 years and mean age at the onset of domperidone were 32.8±2 days. No difference in corrected QT interval was observed between just before and 3, 7 and 14 days after the start of the treatment. Two infants had corrected QT interval prolongation without any clinical side effect that resolved spontaneously.Conclusion:Our experience suggests that domperidone administered cautiously in modest doses does not result in arrhythmias or conduction defects in premature infants statistically. Additional data are needed to give optimal advice regarding the safety of domperidone treatment in premature infants.
It has been reported that gentamicin causes natriuresis, magnesuria and calciuria in neonates. The aim of this study was to determine the acute effects of trough and peak levels of gentamicin on the values of serum creatinine (SCr), urine albumin/urine creatinine (UA/UCr), fractional excretion of sodium and potassium (FENa, FEK) and urine calcium/urine creatinine (UCa/UCr) in preterm neonates treated with gentamicin for suspected infection. Baseline levels of serum and urine Cr, Na and K and urine albumin and Ca levels together with trough and peak gentamicin levels were measured in 61 preterm neonates at the start of the therapy, on the day of the third gentamicin dose and 48-72 h after the cessation of the gentamicin therapy. Therapeutic trough and peak levels were recorded in 56 (91.8%) and 39 (63.9%) of the preterm neonates, respectively, whereas high trough (>2 mg/dl) and peak (>9.99 mg/dl) levels were recorded in five (8.1%) and 11 (18%) of the 61 preterm neonates, respectively. Trough and peak levels of gentamicin were positively correlated with SCr, UA/UCr, FENa, FEK and UCa/UCr values. The UA/UCr, FENa and UCa/UCr values recorded during treatment were statistically significantly different from sub-therapeutic, therapeutic and high peak gentamicin levels. Gentamicin was found to have a serum peak level-dependent microalbuminuric, natriuric and calciuric effect in preterm neonates. Based on these results, we suggest that when the monitoring of serum gentamicin levels is not possible, the monitoring of UA/UCr, FENa and UCa/UCr can be useful as a noninvasive alternative.
Premature infants<1500 g were randomly assigned to study and control groups. In the study group, 42 premature infants received recombinant human erythropoietin (r-Hu EPO) 750 U/kg per week subcutaneously from day 5 to 40 and enteral iron supplementation of 2 to 6 mg/kg/d beginning on day 14 provided that they were receiving at least 50% energy intake orally. In the control group, 51 infants received the same dose of enteral iron supplementation beginning at the end of the fourth week. At the end of a 12-week monitoring period, r-Hu EPO combined with early enteral iron reduced transfusion needs only in the subgroup<1000 g. r-Hu EPO and early iron treatment had no effect on the development of severe retinopathy of prematurity, intraventricular hemorrhage, necrotizing enterocolitis, and bronchopulmonary dysplasia. We suggest that r-Hu EPO combined with early enteral iron is both effective and safe in infants<1000 g.
