BACKGROUND/OBJECTIVES: Vitamin D plays an important role in skeletal growth and maintenance and in the prevention of various diseases. We investigated the relationship between vitamin D intake and bone mineral density (BMD) in Korean adults aged ≥ 50 years using the 2009 Korea National Health and Nutrition Examination Survey data. SUBJECTS/METHODS: This study was conducted in 1,808 subjects aged ≥ 50 years with BMD data in Korea. Dietary vitamin D levels were assessed by the 24-hour recall method. BMD was measured using dual-energy X-ray absorptiometry. We investigated general characteristics and the association between these characteristics, vitamin D status, and BMD. RESULTS: Vitamin D intake was significantly lower in the osteoporosis group among women (P < 0.05). Among all subjects, the higher the serum 25(OH)D concentration, the higher the whole-body total BMD (WBT-BMD), femoral total hip BMD, and femoral neck BMD (P < 0.01). In the serum vitamin D-deficient group of both the total population and women, serum 25(OH)D concentration was associated with WBT-BMD (P < 0.05). Among women with a calcium intake < 537.74 mg/day, BMD of those with a vitamin D intake > 2.51 µg/day (average intake of women) was higher than that of women with a vitamin D intake ≤ 2.51 µg/day (P < 0.001). CONCLUSIONS: Korean adults should increase their BMD by increasing serum 25(OH)D concentration. Furthermore, increasing vitamin D intake could improve BMD, especially in Korean women who consume less calcium than the estimated average requirement.

Uterine anomalies have been reported in 4% of women with infertility and in up to 15% of those with recurrent abortion. One of the major intrauterine disorder associated with infertility and recurrent abortions is intrauterine septum, The reproductive outcome of 41 patients of intrauterine septum (7 complete, 34 incomplete) with repeated abortions or infertility was assessed after the uterine septotomy. 5 of 7 patients with comlete uterine septum undergone uterine septotomy (3; hysteroscopic metroplasty, 2; abdominal metroplasty) had total 6 pregnancies and all of them had live biths. 28 patients with incomplete uterine septum got the hysteroscopic intrauterine septotomy and the viable pregnancy rate was 62% (3 ongoing pregnancies, 13 live biths of total 26 pregnancies). 6 patients with incomplete uterine septum had not the operation and 5 patients had 5 live births after total 6 pregnancies with 1 spontaneus abortion. Even though, the number of cases were small, the live birth rate in the group of septotomy of the patients of complete uterine septum (100%, 6/6) was higher than that in the group of not-done (50%, 1/2). The live birth rate in the group of not-done of the patients with incomplete uterine septum (83%, 5/6) was higher than that in the group of hysteroscopic uterine septotomy (62%, 16/26), but 5 of 6 had short uterine septal length (<1 cm), 1 had 1.5 cm septal length in the group of not-done. All the patients with successful pregnancy outcome had no other co-factors at the diagnostic laparoscopy, but the 5 primary infertility patients with no live birth even after treatment (all were with incomplete septum; 3 undergone hysteroscopic septotomy, 2 not-done with one abortion) had other co-factors such as endometriosis, peritoneal or tubal facor. In conclusion, hysteroscopic uterine septotomy would be useful for the patients with habitutal abortion or infertility and more advanced managemnet protocols should be applied to the patients having other co-factors if there was no pregnancy even after the uterine septotomy.

BACKGROUND: Claudins are integral membrane proteins at tight junctions of simple epithelium and have an important role in cell-cell adhesion and barrier function. Their altered expression modifies the biological function and behavior of epithelial cells. OBJECTIVE: The purpose of this study was to observe the distribution and the degree of expression of claudin-1 during fetal skin development. METHODS: The expression of claudin-1 in the fetal skin was analyzed after immunohistochemical stain was performed on paraffin embedded tissue of sole and scalp of 34 human fetuses, ranging from 10 to 39 weeks of gestational age, using anti-human monoclonal antibody against the claudin-1. RESULTS: Claudin-1 appeared strongly in the sole skin at the 12th week of gestation thereafter expressed more in middle layer in epidermis of the sole and the scalp. Inner root sheaths and early hair germ cells were strongly positive in fetal hair development. Eccrine gland epithelium was positive in later stages. Focal positive expression in superficial layer and strong in middle layer were noted in oral mucosa side of the lip. CONCLUSION: Claudin-1 showed slightly different expression in skin and oral mucosa and has a important role in the development of tight junction and barrier formation in skin and mucosa during fetal stage.

PURPOSE: Tuberculosis of the thyroid gland is very rare and some cases were reported in Korea since 1968. We experienced a case of tuberculous thyroiditis and found a old case in our medical center. This report is about the two case and the review of all cases reported about tuberculosis of the thyroid gland in Korea. METHODS: We present the case of a 55-year-old woman with thyroid tuberculosis who has been treated with antituberculous medication because of tuberculous meningitis during 6 months. We performed thyroid isthmectomy and she is now taking the antituberculous drugs. We found a case of 40- year-old woman who underwent extended thyroid lobectomy, Lt. in 1985 at our medical center. We reviewed the 18 literatures with 29 cases of tuberculosis of the thyroid gland reported in Korea and analyzed total 31 cases (reported 29 cases and our 2 cases). RESULTS: 28 patients were women and only 2 patients were over 60 years old. 26 patients had complained the neck mass. Duration of symptoms were below 6 months in 18 cases. There were associated symptoms like as weight loss, easy fatigue or generalized weakness, dysphagia, palpitation, fever, chills and/or anorexia. Only 9 patients had underlying tuberculosis - 2 meningitis, 2 pneumonia, 3 lymphadenopathy and 2 pneumonia combined with meningitis. But 3 patients were newly diagnosed as old or active pulmonary tuberculosis at the time of diagnosis of thyroid tuberculosis. Thyroid function was normal in 9 cases and abnormal in 5 cases. 3 cases were diagnosed nonoperatively and 15 patients of surgically treated 28 cases were underwent lobectomy. AFB stain was positive in only 13 cases and 2 cases were positive of culture with negative AFB stain. All of cases were diagnosed by pathology as granulomatous tuberculosis with caseous necrosis. CONCLUSION: Either surgical resection plus antituberculous medications or only medications are effective and recurrences were not reported after any initial treatments. So preoperative evaluation is very important and will guide the patient and the surgeon to the most effective management.

Chondroid syringoma, also known as `mixed tumor of the skin', is a kind of acquired hamartoma of folliculosebaceous-apocrine lineage. Histologically, it is characterized by the biphasic pattern, with epithelial structures enveloped by abundant stroma. We report a case of chondroid syringoma, as an asymptomatic nodule, on the upper lip of a 55-year-old male. Histologically, the tumor had both epithelial components with follicular differentiation and myxochondroid stroma.

OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) is one of the well known complication of conttolled ovarian hyperstimulation. Though there have been numerous protocols for the prevention of OHSS, it has not been completely preventable until now. This study was performed to identify clinical predictors for early and late OHSS. METHODS: A retrospective analysis of all IVF cycles in 1993 up to June 1996 was performed. OHSS was diagnosed using the criteria of Rabau modified by Schenker. All cases of OHSS reported in this study presented with marked ovarian enlargement, ascites, oliguria, hemoconcentration and electrolyte disturbance. Ovarian stimulation was carried out using a combination of gonadotrophin releasing hormone-agonist, follicle-stimulation hormone and human menopausal gonadotrophin. 27 patients has moderate or severe OHSS presenting 3-7 days post-human chorionic gonadotrophin (hCG), and 21 patients had severe OHSS presenting 12-17 days post-hCG. RESULTS: No patient with early OHSS went onto develop late OHSS, and no patient with late OHSS had demonstrated early OHSS. Logistic regression showed that early OHSS was predicted by the number of oocytes retrieved and the estradiol concentration on the day hCG injection (P<0.05). Late OHSS was predicted by the transferred embryos, B-hCG on 14 day after hCG injection (P<0.05). CONCLUSION: Early OHSS was an acute effect of the hCG administered prior to egg retrieval in women with high estradiol and large number of retrieved oocytes. Our analysis of the risk factors for early OHSS indicates that cryopreservation of all embryos will not alter the risk of early OHSS even though it should prevent late OHSS. Late OHSS was induced by the rising serum concentration of hCG produced by the early pregnancy, the number of transferred embryos must be adjusted carefully, since it was associated with multiple gestation.

The purpose of this study was to investigate the effect of 3-month nutrition education (First Time Intervention, FI) + additional 3-month nutrition education (Repeated Intervention, RI) which was performed after the 8-month follow-up. FI was conducted during 0-3 months and RI for 11-14 months. Ninety-two subjects completed FI program, and 38 out of 92 subjects who received FI finished the RI. Anthropometric data, dietary assessment (24hr recall) and fasting blood analysis were measured at 0 month, 3 months, 11 months and 14 months time points. After FI (3 mo), waist circumference, triglycerides, total cholesterol were significantly decreased. At 11 month follow-up, body weight, BMI, hip circumference, SBP, DBP were significantly rebounced and HDL cholesterol was significantly decreased. Therefore, the effect of short-term nutrition education was not being sustained. After the secondary nutrition intervention (14 mo), waist circumference and hip circumference were again significantly decreased. Total diet quality index-international (DQI-I) score was significantly increased in both FI group and RI group. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.129, p < 0.05) and counts of nutrition education (r = 0.159, p < 0.05), indicating that effective nutrition education helps improve the diet quality leading to a possible role in CVD prevention among male workers. Although a short-term intervention seems to be a success, the effect was not retained in this study. Therefore, we suggest incorporating nutrition education as a routine program for male worker at worksite.

OBJECTIVE: The aim of study was to evaluate the efficacy of medical and/or laparoscopic surgical treatment for improvement of reproductive outcome of in vitro fertilization and embryo transfer (IVF-ET) in the patients with endometriosis. METHODS: 296 IVF-ET cycles except 18 cycles of cancelled embryo-transfer (unfertilization; 16 cycles, high risk of ovarian hyperstimulation syndrome; 2 cycles) in 191 infertile women with endometriosis from January 1, 1995 to December 31, 1998 were included in this study. All women's ages were < or = 35 and the factor for infetility was endometriosis only and day 3 follicle stumulating hormone (FSH) level of all the cycles was < or = 10 mIU/ml in this study. All the baseline study about infertility was done before initiating treatment of infertility. The stage of endometriosis was recorded during diagnostic laparoscopy by WHO critera. Medical treatment (GnRH agonist or danazole) or laparoscopic surgery was done independently or combinedly by the physician's decision according to the disease entity and symptoms. Short or long protocols were used for controlled ovarian hyperstimulation and 3 day embryos were transferred (maximally 4 embryos) by standard procedures in our institute. We classified the cases as 4 groups : group 1 (without pre-treatment, 80 cycles), goup 2 (laparoscopic surgery only, 37 cycles), group 3 (medication only, 140 cycles), group IV (combined pre-treatment, 39 cycles). RESULTS: The mean age (years old, mean +/- SEM) was 31.5 +/- 0.3 (group 1), 31.6 +/- 0.5 (group 2), 31.5 +/- 0.2 (group 3), 31.7 +/- 0.4 (group 4) respectively. The duration of infertility (months) was 57.7 +/- 3.3, 64.5 +/- 4.8, 59.1 +/- 1.9, 52.0 +/- 3.7 respectively among groups. The viable pregnancy rate (over 28 gestational weeks, VPR) was 12.5 % (10/80) in goup 1, 13.5 % (5/37) in goup 2, 14.3 % (20/140) in group 3, 30.8 % (12/39) in group 4 and there was statistically significant difference between group 1 and group 4 (P=0.03, Chi square test). The total used gonadotropins (ampules) for controlled ovarian hyperstimulation were 28.2 +/- 0.6.

OBJECTIVE: To evaluate the difference of implantation rate (IR) and clinical pregnancy rate (CPR) between two protocols of endometrial preperation in women undergoing frozen-thawed embryo transfer (FET) cycles. METHODS: This study was performed during the different time periods: A retrospective study from January 2000 to June 2001 (phase I) and a prospective study from July 2001 to March 2002 (phase II). All the patients received estradiol valerate (6 mg p.o. daily) starting from day 1 or 2 of the menstrual cycle without pituitary down regulation. Progesterone was administered around day 14 after sonographic confirmation of endometrial thickness > or = 7 mm and no growing follicle. In Group A (n=88, 99 cycles) of phase I, progesterone was administered i.m. at a dose of 50 mg daily from one day prior to thawing of pronuclear (PN) stage frozen embryo or three days prior to thawing of 6-8 cell stage frozen embryo and then each stage embryos were trasnsferred 2 days or 1 day later after thawing. In Group B (n=246, 299 cycles) of phase I, patients recieved progesterone 100 mg i.m. from one day earlier than group A; two days prior to PN embryo thawing, four days prior to of 6-8 cell embryo thawing. During the phase II, to exclude any differences in embryo transfer procedures, in Group 1 (n=23, 28 cycles) of phase II embryo was transfered by one who have used the progesterone protocol since the phase I. In Group 2 (n=122, 139 cycles) of phase II embryo was transfered by one who use the progesterone protocol from the phase II. RESULTS: When compared across the phase and group, there were no significant differences in the characteristics. During the phase I, there were significant increase in IR (14.4% vs 5.9%, p=0.001) and CPR (28.3% vs 14.5%, p=0.000) in group A. During the phases II, IR (11.8% vs 10.6%) and CPR (27.6% vs 27.3%) show no differences between two groups. CONCLUSIONS: In FET cycles, IR and CPR are increased significantly by the change of dosage and timing of progesterone administraton. And the timing is considered to be more important factor because the dosage of progesterone did not affect implantation window in previous studies. Therefore, we suggest that progesterone administration in FET cycle should begin from one day prior to PN stage embryo thawing and three days prior to 6-8 cell stage embryo thawing.
