Effects of giardiasis on school success, weight and height indices of primary school children in Turkey.

BACKGROUND: Giardia intestinalis, the most common parasite in the world, causes several adverse effects on school children, with the prevalence rate ranging between 7.3% and 28% (mean 13.8%) in Turkey. The aim of the present study was to investigate possible adverse effects of G. intestinalis on success at school, and the mean weight and height of primary school children in Sivas, Turkey. METHODS: Five primary schools from central Sivas, Turkey, had a number of students from different socioeconomic conditions and regions. The stool specimens were examined by light microscopy for giardiasis using saline-Lugol and/or zinc sulfate flotation method. Three groups in the present study include the symptomatic giardiasis group (SG), which included children with giardiasis along with abdominal pain and/or diarrhea, the asymptomatic giardiasis group (ASG) without any symptom and the non-parasitic (NPG) group without any parasites. RESULTS: While 599 (34.6%) out of 1730 children were parasitic, 192 (11.1%) had only G. intestinalis. Ninety-eight (5.7%) of 192 were SG (with diarrhea and/or abdominal pain and 94 (5.4%) were ASG. The weights and heights were lower in the children with giardiasis than the children without any parasite. There was a significant difference between the giardiasis group and NPG when the numbers of persons living in the house were compared. While there were no significant difference between the giardiasis group and NPG when the sexes were compared, success at school and economical levels were found to be significantly different between these groups. CONCLUSION: There was a higher prevalence of giardiasis in primary school children and their physical and mental conditions were affected adversely. Giardia infections in particular have adverse effects on success at school.

Do absorbable sutures exacerbate presternal scarring?

We investigated cosmetic outcomes of the midline sternotomy incision. A randomized clinical trial was conducted in 60 patients who underwent surgery through a midline sternotomy incision. Patients were divided into groups A (n=30) and B (n=30). In addition, the incision line was also divided into 2 regions (upper and lower halves) in each group. In group A, the upper half of the skin was closed with absorbable 4-0 braided polyglycolic acid sutures (Sentesorb, Boz; Ankara, Turkey), and the lower half was closed with 4-0 nonabsorbable monofilamentous polypropylene suture (Monoplene, Boz), and vice versa in group B. Scar width and height were measured and photographed at the 6th postoperative month. In both groups, the lower part of the incision showed inferior cosmetic results, regardless of the suture material (P <0. 05). On the other hand, the upper part of the incision in group A (the area of absorbable polyglycolic acid sutures) was significantly more hypertrophic. We conclude that monofilament nylon sutures diminish the risk of hypertrophic scarring, in comparison with absorbable sutures. In the lower half of the sternotomy scar, increased tension and relative mobility of the skin over the xiphoid process lead to inferior cosmetic results, regardless of the suture material used.

Umbilical serum insulin-like growth factor 1 (IGF-1) in newborns: effects of gestational age, postnatal age, and nutrition.

AIM: The aim of this study was to determine the relationship between nutrition, gestational age, and birth weight, and serum insulin-like growth factor 1 (IGF-1) levels in newborns. METHOD: The first study group consisted of sixty newborns: thirty were fed with human breast milk and the others were fed with infant formula. Serum samples were obtained from all the newborns on days one and seven of life. Seventy-two pregnant women and their neonatal cord blood serum samples were obtained in a labor ward in the study group. All the serum samples were analyzed for IGF-1 by immunoassay. RESULT: Newborns fed with human milk had higher serum IGF-1 concentrations compared to formula-fed controls (p < 0.05). Cord IGF-1 levels showed a negative correlation with birthweight (p < 0.05) and a positive correlation with gestational age (p < 0.05). CONCLUSION: These findings suggest that IGF-1 levels during the neonatal period are influenced by gestational age, birth weight, and nutrition.
