Vitamin D deficiency in pregnant women and their neonates in spring time in western Turkey.

Abstract: Although Turkey is located in a sunny region, vitamin D deficiency is still a serious health problem in pregnant women and their infants, especially among the low socio-economic status Turkish population. This study was carried out in order to measure serum 25-hydroxyvitamin D3 [25(OH)D] concentrations of the pregnant women in the last trimester and in their neonates at delivery and to determine the factors associated with maternal serum 25(OH)D concentrations. Among the patients visiting the Ege Obstetrics and Gynecology Hospital in the period March to May 2008, 258 healthy pregnant women ≥37 weeks of gestation were included in this study. The information on different characteristics such as the number of pregnancies and births, nutritional status, vitamin and mineral support during gestation, educational status, clothing style and the economic level of the family was collected from women. Blood samples from the mothers and umbilical cord of the newborns were taken to measure 25(OH)D. The mean 25(OH)D concentrations of the mothers and their infants were 11.5 ± 5.4 ng/mL and 11.5 ± 6.8 ng/mL, respectively. We found a strong positive correlation between maternal serum and umbilical cord blood 25(OH)D concentrations (r = 0.651, P < 0.001). The concentration of 25(OH)D was ≤20 ng/mL in 233 mothers (90.3%) and ≤10 ng/mL in 130 mothers (50.4%). Maternal serum 25(OH)D concentrations related strongly to factors such as uncovered dressing style, sufficient consumption of dairy products and multivitamin use during gestation (P < 0.05). About half (52.7%) of these women had a covered dressing style. 25(OH)D concentrations of these covered dressing mothers and their infants were 9.7 ± 5.1 ng/mL and 9.7 ± 5.6 ng/mL, respectively, which were significantly lower compared with those of uncovered mothers and their babies (P < 0.001). This study showed that, despite a sunny environment, vitamin D deficiency and insufficiency are highly prevalent among the mothers and their neonates. This is generally due to the life style and nutritional status of the mothers. These findings suggest that much more effective vitamin D prophylaxis programmes should be implemented for pregnant women as well as for their babies.

Association of Maternal-Child Characteristics as a Factor in Early Childhood Caries and Salivary Bacterial Counts

Abstract: The aim of this study was to investigate the caries-related microorganisms in saliva and the prevalence of Early Childhood Caries (ECC) in 15- to 35-month-old Turkish children and their associations with the characteristics of the mothers, socioeconomic criteria, and feeding habits of the children. Methods: Saliva samples of 101 children were studied to determine the numbers of Streptococcus mutans, lactobacilli, and Candida albicans. A questionnaire regarding the characteristics of the mothers, socioeconomic criteria, and feeding habits of the children was carried out before the dental examinations of the mother-child pairs. Results: The regression analyses revealed DMFS scores of the mothers as an impact factor for the children’s caries experience. The prolonged feeding bottle-feeding with sweetened milk, pacifier use, and maternal sharing were strongly associated with the colonization of S mutans, lactobacilli, and C albicans, respectively. A significant correlation was also found between maternal education and S mutans. Conclusion: Data indicated that the mother’s DMFS scores, education, and feeding habits were strong risk indicators for the colonization of caries-related micro-organisms and ECC.

Rubella seroprevalence in an unvaccinated population in Izmir: recommendations for rubella vaccination in Turkey.

Abstract: Background. The European Advisory Group on the Expanded Program on Immunization of WHO has recommended that by 2010 or earlier congenital rubella should be well-controlled or eliminated in all countries in Europe. Debate on the introduction of rubella vaccine into national immunization schedules continues to occur, and data on rubella and congenital rubella syndrome in Turkey are insufficient. Objective. To determine age-specific rubella seroprevalence in the 1- to 29-year-old unvaccinated population in Izmir, Turkey. Methods. A total of 600 unvaccinated persons 1 to 29 years old were selected for the study with cluster sampling in Izmir, Turkey. The information on sociodemographic characteristics and disease history was gathered for each participant, and in 580 of them rubella-specific IgG antibodies were assayed quantitatively by the micro-enzyme immunoassay. Results. Of the 580 participants tested for rubella antibodies, 135 (23.3%) were seronegative. The proportions of susceptible individuals were 61.7, 29.5, 12.4, 10.3 and 8.4% in the age groups of 1 to 4, 5 to 9, 10 to 14, 15 to 19 and 20 to 29 years, respectively. Of the young women 15 to 19 years of age, 13.5% were susceptible to rubella infection. Conclusions. Because a substantial proportion of women in their childbearing years are susceptible to rubella, immunization efforts should be directed at infants or prepubertal children.

Evaluation of sponging and antipyretic medication to reduce body temperature in febrile children

Abstract: Two hundred and twenty-four children aged 6 months to 5 years, with rectal temperatures greater than or equal to 30 degrees (104 degrees F), were randomly treated with sponging alone or with medication including a single oral dose of aspirin 15 mg/kg, or paracetamol 15 mg/kg, or ibuprofen 8 mg/kg. Twenty-three children were excluded from the final analysis because they did not complete the study. Demographic characteristics of the patients were found to be comparable in all groups. Rectal temperatures were recorded every 30 min for a 3 h period. During the first 30 min of intervention, sponging was found to be more effective than all of the three medications. After 60 min, the effects of each medication became superior to sponging with tepid water in reducing body temperature. Twenty-three children were excluded from the final analysis because they did not complete the study. Comparing the effect of the three different medications, it was seen that the antipyretic efficacy of aspirin and ibuprofen were significantly more than paracetamol 3 h after intervention (P < 0.05). For the management of fever over 39 degrees C, it is therefore recommended to give children an antipyretic drug, preferably ibuprofen, and at the same time to begin sponging to provide a rapid and sustained antipyresis

Guidelines for the investigation and management of idiopathic thrombocytopenic purpura in adults, children and in pregnancy

Abstract: Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by persistent thrombocytopenia (peripheral blood platelet count < 150 · 10 ⁄ l) due to autoantibody binding to platelet antigen(s) causing their premature destruction by the reticuloendothelial system, and in particular the spleen (Woods et al, 1984a,b). Although the basic underlying pathophysiology of ITP has been known for 50 years (Harrington et al, 1951), the literature shows that the investigation and management of patients with thrombocytopenia vary widely, and is not evidence-based, due to a lack of clinical trials and quality research. Despite major advances in our understanding of the molecular basis of many blood disorders, the diagnosis of ITP remains one of exclusion; there are currently no robust clinical or laboratory parameters that are able to establish the diagnosis of ITP with accuracy. This guideline aims to assess available diagnostic tests and therapies, and attempts to provide a rational approach to the diagnosis and treatment in adults, children and in pregnancy. Although natural history data are becoming available (Cohen et al, 2000; Djulbegovic & Cohen, 2001; Portielje et al, 2001), there are few randomized trials in ITP and many of the recommendations, like those of the American Society of Hematology (ASH) Panel (George et al, 1996), are based on expert opinion.
