Our data demonstrate that ADMA and ox-LDL levels in adolescent PCOS subjects were not different than those in controls. Abnormal lipid profile was shown in obese and nonobese girls with PCOS and leptin was related with these lipid abnormalities in the PCOS subjects.
ObPCOS and LeanPCOS groups having higher LH/FSH ratios and lower SHBG levels suggest that there could be factors other than adiposity responsible for the clinical features of PCOS patients. In the light of our results, those factors can be suggested as ghrelin and E2 for the elevated LH/FSH ratio and resistin for the lowered SHBG.
Hyperthyrotropinaemia, in which normal levels of T4 occur in association with raised thyroid stimulating hormone (TSH), is usually picked up on neonatal screening. High TSH level can continue for a long time in some of the cases. There is no consensus concerning the follow-up or treatment plan for hyperthyrotropinaemia. In this study, results of a 4-year follow-up of 36 cases who had been medically treated are discussed. Low-dose (5 microg/kg/day) L-thyroxin treatment was carried out in 36 cases that had 5 mU/l or higher TSH and showed exaggerated response to TRH test. Dose was decreased to 2-3 microg/kg/day in 24 of these patients during 6 months follow-up. The drug was stopped in three cases because of the development of biochemical hyperthyroidism. Denver developmental assessment test was applied to all cases at the end of the third year. All patients showed a normal development in relation to their age. According to our results, cases with hyperthyrotropinaemia need to be followed regularly for a long time and a need for low-dose L-thyroxin treatment may exist at ages varying from patient to patient.
Abstract. This study is planned to investigate the role of ghrelin in normal variant short stature. Serum ghrelin, IGF-I and IGFBP-3 levels were measured in 17 children with constitutional delay of growth, 19 children with familial short stature and 11 age matched healthy children. Mean bone age of the constitutional delay of growth group was lower compared to other groups. Constitutional delay of growth group had lower mean weight compared to the controls. Serum IGF-I values were lower in the constitutional delay of growth group compared to the familial short stature and control groups. IGFBP-3 levels of the groups were similar. Ghrelin levels were higher in the short stature groups compared to the controls. In the multiple regression analyses, weight (β = -.54, p<0.0001) and height SDS (β = -.33, p = 0.01) were the independent determinants of ghrelin. The results of this study, the first one in which ghrelin levels are investigated in normal variant short stature, suggest that ghrelin does not play a role as a cause, but as a consequence in these patients because it is negatively correlated with weight and height standard deviation score. These negative correlations can be attributed to the compensatory response of ghrelin, which deserves further attention in future studies.
BMD is affected in diabetic children, and HbA1c(whole) and diabetes duration are the most important determinants. Pubertal stage is another determinant of BMD, especially in newly diagnosed patients.
Background:In several studies, since high and low birth weights are demonstrated as associated with obesity in childhood, these values should be followed up and documented carefully. Objective: The aim of this retrospective cohort study is to demonstrate the variation on body mass index outcomes of large (LGA), small (SGA), appropriate (AGA) for gestational age infants from birth to the end of fourth year of age and the effects of breastfeeding duration on these outcomes. Methods and results: Four hundred and seven infants were recruited in the study (304 AGA, 85 LGA, 18 SGA infants).LGA was frequent in boys and SGA in girls (p = 0.001). The mothers with gestational diabetes mellitus did have LGA infants (10.0 % vs. 3.3 % ) (p = 0.022). The SGA infants performed rapid catch-up growth in the second month while the LGA infants performed catch-down growth in the ninth month. After the fi rst 4 months, there was no difference on the values of BMI depending on breastfeeding time, less or more than 4 months, on the basis of the AGA and LGA infants. However, the body mass index (BMI) of LGA infants breastfed more than 12 months were not different from the AGA; unless the breastfeeding ceased earlier, the means of BMI remained signifi cantly higher until 3 years. Conclusion: Consequently, long duration of breastfeeding might protect LGA infants from childhood obesity risk.
Background: Persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is characterized by disproportional secretion of insulin from pancreatic beta-cells. Although one of the manifestations of hypoglycemia is West syndrome, it is rarely reported in PHHI. Patient report: A 6 month-old girl who was followed up with the diagnosis of PHHI was admitted to hospital with the complaint of jerky movements at her extremities. EEG revealed the typical pattern of hypsarrhythmia leading to the diagnosis of West syndrome. Conclusion: To our knowledge, there is only one report in the literature of West syndrome as a manifestation of PHHI, and that was the hyperammoniemic form of the disease. The present report is the first of normoammoniemic PHHI leading to West syndrome. We wish to highlight the potential risks of PHHI, especially in inadequately treated patients, and to emphasize that close neurological follow-up is very important in children who suffer from PHHI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
