Cutaneous lesions in Turkish neonates born in a teaching hospital.

BACKGROUND: The neonatal period is regarded as the first 4 weeks of extrauterine life. In the literature, there are numerous articles about the skin findings in neonates and the results of these studies show differences according to races and environmental factors. AIMS: Our objective was to evaluate the skin lesions seen in neonates delivered in our hospital and to determine their relationship to gender, gestational age and route of delivery. METHODS: Newborns delivered at the Obstetrics Clinics of our hospital between November 2007 and April 2008 were included in this study. Dermatologic examination was performed and relationship between the 10 most common skin findings and gender, gestational age and route of delivery were statistically evaluated. RESULTS: A total of 572 newborns were examined for the presence of skin lesions. Most common skin findings were Epstein pearls (58.76%), sebaceous hyperlasia (48.45%) and xerosis (31.29%). Milia and sebaceous hyperplasia in girls, desquamation and xerosis in preterms, Epstein pearls, sebaceous hyperplasia and desquamation in vaginally delivered babies were found to be more frequent and the differences were statistically significant. CONCLUSION: We found that 90.7% of the neonates had one or more cutaneous lesions. Maturity and type of delivery of the babies were important factors in their causation. In Turkey, this study is the first study performed on the skin lesions seen during the neonatal period. With this study, we want to increase the awareness about the skin findings in neonates.

Plasma nitric oxide, endothelin-1 and urinary nitric oxide and cyclic guanosine monophosphate levels in hypertensive pregnant women.

OBJECTIVE: To compare serum levels of nitric oxide (NO) and endothelin-1 (ET-1), and urinary concentrations of NO and cyclic guanosine monophosphate (cGMP) between preeclamptic and normotensive pregnant women. METHOD: Ninety-one preeclamptic (48 mild, 43 severe) and forty healthy normotensive pregnant women above 32 gestational weeks were recruited into study. Chemiluminesence technique was used for measuring plasma and urinary NO levels, and radioimmunoassay was used to determine plasma ET-1 and urinary cGMP levels. RESULT: Plasma and urinary NO, and urinary cGMP levels were significantly lower in preeclamptics than in the control group (respectively, p< 0.001, p< 0.001, p< 0.01). Plasma ET-1 levels were significantly higher in the preeclamptics than in the control group (p<0.001). There were significant negative correlations between plasma ET-1, plasma NO and urinary NO and cGMP in all groups. There were positive correlations between plasma NO, urinary NO and cGMP in all groups. CONCLUSION: The imbalance between NO and ET-1 may play a significant role in the pathophysiology of preeclampsia.

Efficacy of tibolone and transdermal estrogen therapy on psychological symptoms in women following surgical menopause.

OBJECTIVE: This study investigated the efficacy of tibolone and transdermal estradiol therapy on menopausal and psychological symptoms in women following surgical menopause. METHOD: Seventy-five women who had undergone surgical menopause were randomized to a 6-month double-blind interventional study treatment with oral 2.5 mg/day tibolone, transdermal 3.9 mg/week estradiol or oral placebo. The patients were assessed using Kupperman's Scale, Hamilton Depression Rating Scale (HDRS) and Hamilton Anxiety Rating Scale (HARS) before and at the end of the 6 months of treatment. RESULT: Sixty-five subjects completed the study: 23 on tibolone, 21 on transdermal estradiol and 21 on placebo. At the end of the 6 months of therapy, highly significant improvements in menopausal symptoms, depression and anxiety scores were observed in both groups (tibolone and transdermal estradiol groups) as compared with baseline values (p<0.001). However, in the placebo group, there were no significant differences on changes from baseline to the end of treatment (p>0.05). CONCLUSION: These results suggest that tibolone and transdermal estradiol therapy significantly improve menopausal and psychological symptoms in women following surgical menopause.
