OBJECTIVE: To assess the difference of baseline hormonal status and pathophysiology, and confirm the risk factors for long term complication according to Body Mass Index in women with polycystic ovary syndrome. MATERIALS AND METHODS: Serum level of LH, FSH, Estradiol, Prolactin, Testosterone, DHEA-S, fasting insulin were measured and 100 gm oral glucose tolerance test and endometrial biopsy were performed in total 75 chronic anovulation patients and 20 normal cycling infertility patients. 95 evaluated patients were divided into 3 groups including patients with chronic anovulation having BMI below 25, BMI beyond 25.1, normal cycling infertility patients, Group 1 (n=39), Group 2 (n=36), Group 3 (n=20), respectively. Statistical analysis was performed respect to relationship between BMI and measured hormone level, sum of glucose level during 100 gm OGTT, insulin resistance using t-test, ANOVA test, Post Hoc test, Mann-Whitney test. p<0.05 was considered as statistically significant. RESULTS: Serum LH level and LH/FSH ratio was significantly higher in Group 1, compared than Group 2 or 3 (p<0.05), BMI and LH, LH/FSH ratio was negatively correlated (r=-0.351, r=-0.318). There was no significant difference according to BMI in FSH, testosterone, estradiol, prolactin, DHEA-S level. Fasting insulin and sum of glucose level during 100 gm OGTT were significantly higher in Group 2 compared than Group 1 or Group 3 (p<0.05), there was no significant difference between Group 1 and Group 3. Insulin resistance was more frequently identified in Group 2 compared than Group 1 (p=0.001). CONCLUSIONS: BMI and LH, LH/FSH ratio were negatively correlated, so clinical significance of LH, LH/FSH ratio in diagnosis of PCOS may be attenuated by increasing body weight. Overweight patients with chronic anovulation may be the risk group for developing insulin resistance, hyperinsulinemia, glucose intolerance, later type 2 DM. Hyperinsulinemia may operate mainly in overweight chronic anovulation patients in development of hyperandrogenism.

Port-wine stains (PWSs) are benign congenital vascular malformations that most commonly occur as isolated lesions on the face, neck and trunk. The major indication for therapy in most patient, regardless of age, is psychological burden imposed by the PWSs. A Candela SPTL-1 flashlamp-pumped pulsed dy laser (Candela Corp. Wayland, Mass.) using the principle of selective photothermolysis was used. Selective cutaneous vascular damages are influenced by the wavelength. pulse duration and energy density of the laser. To evaluate histopathological changes according to energy densities are essential to treat cutaneous benign vascular lesion by the iaser. 5 patients with PWSs were treated with the Candela SPTL-1 laser. Lesions were biopsied and analized immediately after laser exposure. 2 days and 7 days after laser exposure. The results were as follows : 1. Depth of penetration The penetration depth was increased from .2mm to 1.9mm with energies ranging from 6J/cm(2) to 10J/cm(2) respectively. 2. Nonvascular damages of epidermis & dermis Focal epidermal vacuolization has been observed in biopsy specimens immediately after laser exposure with energy density 6J/cm(2). As energy densities increased from 6J/cm(2) to 10J/cm(2), histopathological changes got worsened with appearance of vesicles. subepi dermal seperations and epidermal necrosis. 2. Vascular damages of dermis Multiple foci of agglutinated RBC, fibrin and platelet thrombi within the dermal blood vessels have been observed in biopsy specimens immediately after laser exposure. There was a pattern of "acute vasculitis" in the upper dermis and a prominent perivascular neutrophilic responses in the mid-dermis 2 days after laser exposure. Dermal vessels with smaller lumen and granulation tissue have been observed in biopy specimens 7 days after laser exposure. In summary, penetration depth of laser beam and nonvascular epidermal and dermal damages were directly proportional ot the energy density of the laser. But 7 days after laser exposure, epidermis and dermis showed normal appearance without detectable scarring. This study suggested that Candela SPTL-1 laser is safe and has no scar formation on the treatment of PWSs.

BACKGROUND: Nurses are often exposed to needlestick and sharp-object injuries (NSIs). This study aimed to investigate the post-exposure reporting rate of NSIs among nurses. METHODS: The subjects were 84 nurses from 4 hospitals (3 hospitals with 300 or more beds and 1 hospital with less than 300 beds) who had experienced at least 1 NSI within a 6-month period. The instrument was a self-administered questionnaire, which was based on the EPINet report form and a questionnaire for NSIs among resident physicians, which was used by Choi et al. Data were collected between April 9 and June 15, 2009, and analyzed using descriptive statistics and the chi-square test, which was performed using SPSS with a significance level of 0.05. RESULTS: Among the 84 nurses who had experienced at least 1 NSI within 6 months, only 14.3% had reported the NSIs, and 58.4% of these subjects reported the NSI immediately after sustaining the injury. The most common reason for not reporting was "the patients were found out to be uninfectious" (81.9%) followed by "too busy" (65.3%). The incidence of post-exposure reporting was negatively related to the number of NSIs (chi-square=13.871, p<0.001) and positively related to assessments of infectivity of the patients (chi-square=4.248, P=0.039) and other persons' recommendations to report NSIs (chi-square=4.092, P=0.043). CONCLUSION: The post-exposure reporting rate was very low. The factors responsible for this low rate should be investigated in a more systematic manner, and more measures should be undertaken to increase the reporting rate among nurses.
