Assessment of patient-reported outcomes (PROs): treatment satisfaction, medication adherence, and quality of life (QoL) and the associated factors in postmenopausal osteoporosis (PMO) patients in Korea.

Patient-reported outcomes (PROs) provide practical guides for treatment; however, studies that have evaluated PROs of women in Korea with postmenopausal osteoporosis (PMO) are lacking. This cross-sectional, multi-center (29 nationwide hospitals) study, performed from March 2013 to July 2014, aimed to assess PROs related to treatment satisfaction, medication adherence, and quality of life (QoL) in Korean PMO women using osteoporosis medication for prevention/treatment. Patient demographics, clinical characteristics, treatment patterns, PROs, and experience using medication were collected. The 14-item Treatment Satisfaction Questionnaire for Medication (TSQM) (score-range, 0-100; domains: effectiveness, side effects, convenience, global satisfaction), Osteoporosis-Specific Morisky Medication Adherence Scale (OS-MMAS) (score-range, 0-8), and EuroQol-5 dimensions questionnaire (index score range, - 0.22 to 1.0; EuroQol visual analog scale score range, 0-100) were used. To investigate factors associated with PROs, linear (treatment satisfaction/QoL) or logistic (medication adherence) regression analyses were conducted. A total of 1804 patients (age, 62 years) were investigated; 60.1% used bisphosphonate, with the majority (67.2%) using weekly medication, 27.8% used daily hormone replacement therapy, and 12.1% used daily selective estrogen receptor modulator. Several patients reported gastrointestinal (GI) events (31.6%) and dental visits due to problems (24.1%) while using medication. Factors associated with the highest OS-MMAS domain scores were convenience and global satisfaction. GI events were associated with non-adherence. TSQM scores for effectiveness, side effects, and GI risk factors were significantly associated with QoL. Our study elaborately assessed the factors associated with PROs of Korean PMO women. Based on our findings, appropriate treatment-related adjustments such as frequency/choice of medications and GI risk management may improve PROs.

Effects of Combination Therapy of Alendronate and Hormonal Therapy on Bone Mineral Density in Postmenopausal Korean Women: Multicenter, Randomized Controlled Clinical Trial.

This study evaluated the effects of combination treatment with alendronate (ALEN) and hormone therapy (HT) on bone mineral density (BMD) in postmenopausal Korean women. This multicenter, randomized, controlled clinical trial enrolled 344 postmenopausal women with low BMD. The women received HT (0.625 mg/day of conjugated equine estrogen and 2.5 mg/day of medroxyprogesterone acetate) alone or in combination with ALEN (10 mg/day) for 1 year. Changes in BMD and biochemical markers of bone turnover were evaluated. Data from 203 women (HT alone, 99; combination treatment, 104) who completed this study were analyzed. BMD at the lumbar spine and total hip increased significantly in both treatment groups after 1 year. There were no significant differences between HT alone vs. the combination of ALEN and HT in mean BMD increase at the lumbar spine (6.9% vs. 7.9%) and total hip (3.7% vs. 3.8%). Combined therapy suppressed serum osteocalcin and urinary deoxypyridinoline to a greater extent than HT alone. In conclusion, compared to HT alone, combination treatment with ALEN and HT for 1 year did not offer a benefit in BMD in postmenopausal Korean women with low BMD.

Estrogen-mediated Height Control in Girls with Marfan Syndrome.

This study evaluated the efficacy of a stepwise regimen of estradiol valerate for height control in girls with Marfan syndrome. Eight girls with Marfan syndrome who had completed estrogen treatment for height control were included. Estradiol valerate was started at a dose of 2 mg/day, and then was increased. The projected final height was estimated using the initial height percentile (on a disease-specific growth curve for Korean Marfan syndrome [gcPFHt]), and the initial bone age (baPFHt). After the estrogen treatment, the projected final height was compared to the actual final height (FHt). The median baseline chronological and bone age were 10.0 and 10.5 years, respectively. After a median of 36.5 months of treatment, the median FHt (172.6 cm) was shorter than the median gcPFHt (181.0 cm) and baPFHt (175.9 cm). In the six patients who started treatment before the age of 11 years, the median FHt (171.8 cm) was shorter than the median gcPFHt (181.5 cm) and baPFHt (177.4 cm) after treatment. The median differences between the FHt and gcPFHt and baPFHt were 9.2 and 8.3 cm, respectively. In two patients started treatment after the age of 11, the differences between FHt and gcPFHt, and baPFHt after treatment were -4 and 1.4 cm, and -1.2 and 0 cm for each case, respectively. A stepwise increasing regimen of estradiol valerate may be an effective treatment for height control in girls with Marfan syndrome, especially when started under 11 years old.

Gonadotropin-releasing hormone agonist with add-back treatment is as effective and tolerable as dienogest in preventing pain recurrence after laparoscopic surgery for endometriosis.

PURPOSE: This study was performed to compare the efficacy and tolerability of GnRH agonist with add-back therapy versus dienogest treatment for preventing pelvic pain recurrence after laparoscopic surgery for endometriosis. METHODS: Sixty-four reproductive-aged women who underwent laparoscopic surgery for endometriosis received post-operative medical treatment with either GnRH agonist plus 17ß-estradiol and norethisterone acetate (n = 28) or dienogest (n = 36) for 6 months. The pre- to post-treatment changes in pain were assessed using a visual analogue scale, and changes in quality-of-life and menopausal symptoms were measured by questionnaire. RESULTS: Visual analogue scale pain score decreased significantly for both treatments with no significant differences between groups. Neither physical, psychological, social, and environmental components of quality-of-life nor menopausal rating scale score were significantly different between the two groups. Bone mineral density at the lumbar spine declined significantly in both treatment groups (-2.5 % for GnRH agonist plus add-back and -2.3 % for dienogest), with no significant difference between the two groups. CONCLUSION: GnRH agonist and add-back therapy using 17ß-estradiol and norethisterone acetate are as effective and tolerable as dienogest for the prevention of pelvic pain recurrence after laparoscopic surgery for endometriosis.

Effects of long-term postoperative oral contraceptive use for the prevention of endometrioma recurrence on bone mineral density in young women.

Concerns for negative effects of oral contraceptives (OCs) on bone mineral density (BMD) in long-term users have been raised, since OCs suppress the hypothalamic-pituitary-ovarian axis. However, there have been still limited data regarding the effects of long-term OC use on BMD in young women in the twenties. We investigated the effects of long-term OC use for the prevention of endometrioma recurrence on BMD in young women. Ninety-two women aged 20-30 years who underwent conservative surgery for endometrioma and used postoperative OC for at least 12 months to prevent the recurrence were included for this cross-sectional study, and BMDs after OC use were analyzed. The mean age at starting OC and duration of OC use was 25.6 ± 2.9 years and 40.7 ± 28.5 months, respectively. No correlation was found between BMDs and age at starting OC at all sites. In addition, BMDs were also not correlated with the duration of OC use, and were comparable according to the dose of OC (20 versus 30 µg). In conclusion, long-term use of OCs has no adverse effect on BMD in post-adolescent young women.

Modulation of Bone Mineral Density and Its Response to Menopausal Hormone Therapy according to the Apolipoprotein E Genotype in Postmenopausal Korean Women.

OBJECTIVES: Genetic factors are a major cause of osteoporosis. The present study evaluated the association of the apolipoprotein E (ApoE) genotype with bone mineral density (BMD) and its response to menopausal hormone therapy (MHT) in postmenopausal Korean women. METHODS: This retrospective cohort study included 172 postmenopausal women with no endocrine diseases, medications, or lifestyles that would affect bone metabolism and who were continuously treated with MHT for at least 2 years. BMDs were measured at baseline and periodically. RESULTS: Linear regression analysis demonstrated similar baseline BMDs at the lumbar spine, but significantly lower at the femur neck and total hip in the ApoE ε4 carrier than in the noncarrier group, after controlling for age, body mass index, and history of MHT usage. Overall, the Wilcoxon signed rank test demonstrated that MHT increased the BMD percentage change at all three regions, and the Generalized Estimating Equation (GEE) demonstrated significant time trends at the lumbar spine and femur neck. ApoE ε4 noncarriers exhibited a significant time trend in BMD changes at the femur neck, whereas ε4 carriers exhibited a time trend at the lumbar spine. However, BMD changes at each time point were comparable at all regions between the groups. Notably, GEE adjusted for baseline characteristics and BMD revealed a significant interaction effect of time and ApoE ε4 allele in BMD changes at the femur neck. CONCLUSIONS: Postmenopausal Korean women carrying the ApoE ε4 allele demonstrated a lower hip BMD compared with ε4 noncarriers. Furthermore, the ε4 allele may modulate hip BMD responses to MHT.

Factors associated with the laterality of recurrent endometriomas after conservative surgery.

We evaluated the laterality of primary endometrioma and characteristics of patients according to the laterality of recurrent endometrioma in 140 women with recurrent endometrioma after conservative surgery. Histologically confirmed recurrent endometriomas were found on the left side in 49 patients (35.0%), the right in 44 (31.4%) and bilaterally in 47 (33.6%). The sites of primary endometrioma were not associated with those of recurrent endometrioma, and the recurrence rate in the treated ovary (59.8%) was similar to that of the intact ovary (69.0%) at the primary surgery. Proportions of stage IV endometriosis and posterior cul-de-sac obliteration were higher in patients with bilateral recurrence than in those with unilateral recurrence (p < 0.01 for all comparisons) and in patients with contralateral recurrence than in those with ipsilateral recurrence (p < 0.05 for all comparisons), but no differences were found in other characteristics of participants according to the laterality or pattern of recurrence. In conclusion, the lateral distribution of recurrent endometrioma was not associated with that of the primary lesion, and endometrioma did not recur more frequently in the treated ovary. An advanced stage and the presence of posterior cul-de-sac obliteration were factors associated with bilateral or contralateral recurrence of endometrioma.

Prevalence of hyperprolactinemia in adolescents and young women with menstruation-related problems.

OBJECTIVE: The aim of this study was to evaluate the prevalence of hyperprolactinemia in adolescents and young women with menstrual problems. STUDY DESIGN: This study included 1704 young women with menstruation-related problems. The patients were classified into group I (age, 11-20 years) or group II (age, 21-30 years); the prevalence of hyperprolactinemia was analyzed according to age and categories of menstruation-related problems. RESULTS: For primary amenorrhea and oligomenorrhea, the prevalence of hyperprolactinemia was low in both groups. However, hyperprolactinemia was a relatively common cause of secondary amenorrhea (5.5% for group I and 13.8% for group II, respectively); it was more frequent in group II (P = .001); the prevalence of prolactinoma was also higher in group II (P = .015). For abnormal uterine bleeding, hyperprolactinemia was more common in group II (2.6% for group I and 9.4% for group II; P < .001), but causes were similar. CONCLUSION: Hyperprolactinemia is not rare in young women with menstruation-related problems; its prevalence varies according to age and manifestations.

Estrogen requirements in girls with Turner syndrome; how low is enough for initiating puberty and uterine development?

We conducted this study to find the adequate initial estrogen dose for adolescent girls with Turner Syndrome (TS). We reviewed the medical records of 19 girls with TS and premature ovarian failure (POF), aged 13 to 17 years, who were referred to our adolescent gynecology clinic for ERT. Nine patients were treated with 0.5 mg estradiol valerate (EV) and 10 patients were treated with 1 mg EV as an initial estrogen dose for 1 year. Breast development, changes in uterine size and bone mineral density were measured before and after 1 year of ERT. All patients showed breast budding after 1 year of ERT regardless of estrogen dosage. Uterine development in patients treated with 1 mg EV advanced farther in 1 year of treatment than in patients given 0.5 mg EV. In patients treated with 1 mg EV, uterine length increased by 39.8% and AP fundal diameter by 46%, increments greater than in patients receiving 0.5 mg EV. After 1 year of ERT, bone mineral densities (BMD) increased significantly in both groups, although BMD did not differ significantly between the groups. In conclusion, ERT with 1mg of EV, as a starting dose induced better uterine development than 0.5 mg in prepubertal girls with TS.

Impact of lysophosphatidylcholine on the plasminogen activator system in cultured vascular smooth muscle cells.

The balance between tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor type 1 (PAI-1) regulates fibrinolysis. PAI-1 expression increases in atherosclerotic arteries and vascular smooth muscle cells (VSMCs) are one of major constituents of atheroma. We investigated the impact of lysophosphatidylcholine (lysoPC), an active component of oxidized low-density lipoprotein, on the plasminogen activator system of the rat VSMCs. The lysoPC stimulated the protein and gene expressions of PAI-1 but did not affect the protein expression of t-PA. Fibrin overlay zymography revealed that lysoPC increased the activity of PAI-1 in the conditioned media, while concurrently decreasing that of free t-PA. Vitamin E inhibited the lysoPC-induced PAI-1 expression. Further, lysoPC increased the intracellular reactive oxygen species (ROS) formation. Caffeic acid phenethyl ester, an inhibitor of NF-κB, blocked this lysoPC effect. Indeed, lysoPC induced the NF-κB-mediated transcriptional activity as measured by luciferase reporter assay. In addition, genistein, an inhibitor of protein-tyrosine kinase (PTK), diminished the lysoPC effect, while 7,12-dimethylbenz[a]anthracene, a stimulator of PTK, stimulated PAI-1 production. In conclusion, lysoPC does not affect t-PA expression but induces PAI-1 expression in the VSMC by mediating NF-κB and the genistein-sensitive PTK signaling pathways via oxidative stress. Importantly, lysoPC stimulates the enzyme activity of PAI-1 and suppresses that of t-PA.

Effects of Combination Oral Contraceptives on Bone Mineral Density and Metabolism in Perimenopausal Korean Women.

OBJECTIVES: A retrospective cohort study was conducted to evaluate the effects of combination oral contraceptives (COCs) on bone mineral density (BMD) and metabolism in perimenopausal Korean women. METHODS: The study subjects comprised two groups. The COC group included 55 women who took low-dose COC for at least one year to control vasomotor symptoms. Another 55 women who had annual checkups without history of COC use served as controls. BMD and bone turnover markers were assessed periodically. RESULTS: In the control group, 12-month BMD values at the lumbar spine (LS) and total hip (TH) significantly decreased with a greater magnitude at LS, and bone resorption (BR) and formation (BF) markers increased concurrently with a larger change in BR. COCs increased BMD at LS after 12 months and prevented BMD decline at TH. Multivariable linear regression revealed a significant difference in LS BMD between groups at 12 months. In the COC group, there were significant negative correlations between baseline BMD and Z-score at LS and corresponding changes at 12 months. COCs did not alter BR markers, whereas BF markers were significantly decreased at 3 months. Group comparison at 12 months, as tested with adjusted linear regression, disclosed significant differences in both BR and BF makers. CONCLUSIONS: Bone loss associated with activated bone turnover is evident during the menopausal transition, and COCs might prevent BMD decrease and suppress bone turnover markers in perimenopausal Korean women. Significant increase in LS BMD and decreases in BF makers suggest underlying mechanisms of greater impact on BF.

Efficacy of risedronate with cholecalciferol on 25-hydroxyvitamin D level and bone turnover in Korean patients with osteoporosis.

BACKGROUND: We performed a randomized, double-blind, prospective, 16-week clinical trial to evaluate the efficacy and safety of risedronate with and without cholecalciferol on 25-hydroxyvitamin D [25(OH)D] levels and bone markers in Korean patients with osteoporosis. METHODS: We randomly assigned 164 adults with osteoporosis to one of two treatment groups: weekly risedronate 35 mg and cholecalciferol 5600 IU combined in a single pill (RSD+) or weekly risedronate 35 mg alone (RSD). We measured serum levels of 25(OH)D, parathyroid hormone (PTH), and bone markers and performed muscle function tests, at baseline and after 16 weeks of treatment. RESULTS: After 16 weeks of treatment, mean serum 25(OH)D increased significantly from 39·8 to 70·8 nmol/l in the RSD+ group and declined significantly from 40·5 to 35 nmol/l in the RSD group. Although both treatment groups had significant increases in serum PTH over baseline during the study, the RSD group had a significantly larger increase than the RSD+ group (13·6 vs 4·8 ng/l; P = 0·0005). In both groups, serum bone-specific alkaline phosphatase (BSAP) and C-terminal telopeptide (CTX) declined rapidly; there were no significant differences between groups. There was also no significant difference between groups in lower-extremity function tests. The overall incidence of clinical adverse events was not significantly different between groups. CONCLUSION: In patients with osteoporosis, a once-weekly pill of risedronate and cholecalciferol provided equivalent antiresorptive efficacy to risedronate alone in terms of bone turnover and improved 25(OH)D level over a 16-week treatment period without significant adverse events.

Clinical characteristics of ovarian teratoma: age-focused retrospective analysis of 580 cases.

OBJECTIVE: The objective of the study was to evaluate the clinical characteristics of ovarian teratoma by age. STUDY DESIGN: This was a retrospective study. Five hundred eighty medical records were reviewed from patients who underwent operative removal of ovarian teratomas at Samsung Medical Center between January 1996 and February 2010. RESULTS: The proportion of asymptomatic patients increased significantly after 20 years of age (P = .0006). Ovarian torsion was noted in 26 patients (4.9%), without an age-specific difference (P = .5019; range, 0.0-8.2%). Tumor size was different according to age group (P < .0001), with larger tumor size in younger patients (<20 years old) relative to older patients. Immature teratoma revealed a higher incidence of symptomatic tumors on the first visit and significantly larger tumor size (P = .0004) compared with mature teratoma. CONCLUSION: Patients with ovarian teratoma have different clinical manifestations by age. It could help us understand clinical characteristics of the disease.

Effects of laparoscopic surgery on serum anti-Müllerian hormone levels in reproductive-aged women with endometrioma.

A few studies have investigated the effects of laparoscopic cystectomy for endometrioma on ovarian reserve using serum anti-Müllerian hormone (AMH) levels and have shown inconsistent results. This prospective study was performed to estimate early changes in serum AMH after laparoscopic surgery for endometrioma. In 27 women aged 21-46 years who underwent laparoscopic unilateral cystectomy (n = 13) or oophorectomy (n = 14) for endometrioma, we measured pre- and postoperative serum AMH levels at baseline and 1 week, 1 month, and 3 months after surgery. Serial changes in serum AMH levels were analyzed according to the operation type using analysis of variance. Mean levels of serum AMH decreased significantly immediately after surgery and remained for up to 3 months in both operation types (P = 0.002 for cystectomy group and P <0.001 for oophorectomy group). In addition, the serum AMH levels showed similar patterns of change after cystectomy or oophorectomy. In conclusion, laparoscopic ovarian cystectomy for endometrioma appears to decrease serum AMH levels immediately after surgery.

Effects of menopausal hormone therapy on ambulatory blood pressure and arterial stiffness in postmenopausal Korean women with grade 1 hypertension: a randomized, placebo-controlled trial.

BACKGROUND: Estrogen therapy in early menopausal women decreases the risk of coronary heart disease and parenteral, but not oral, estrogen is reported to reduce blood pressure (BP). Progestogens are typically added to estrogens to prevent unopposed endometrial stimulation. The effects of progestogen on BP have been less well studied to date. This study was conducted to explore the impacts of micronized progesterone (MP4) combined with percutaneous estradiol gel (PEG) on hemodynamics in postmenopausal Korean women with grade 1 hypertension. METHODS: Fifty-two postmenopausal women (aged 49-75 years) with systolic BP (SBP) of 140-160 mmHg or diastolic BP (DBP) of 90-100 mmHg were randomly assigned for 12 weeks to placebo (n = 16), estrogen therapy (ET) (n = 19) with PEG (0.1 %, 1 g./d), or estrogen + progestogen therapy (EPT, n = 17) with PEG and MP4 (100 mg/d). The primary endpoint was ambulatory BP and the secondary endpoints were arterial stiffness as brachial-ankle pulse-wave velocity (baPWV) and aortic parameters on applanation tonometry. RESULTS: One woman in the ET group dropped out, so 51 participants were finally analyzed. Outcome measures for ambulatory BP and arterial stiffness were not different between groups. Within-group comparisons showed that EPT significantly decreased daytime heart rate and baPWV: the changes from baseline (mean ± standard deviation) were - 2.5 ± 5.7 bpm (P = 0.03) and - 0.6 ± 1.4 m/s (P = 0.04), respectively. After adjusting for baseline, linear regression analysis revealed a significant difference in the relationship between baseline and 12-week baPWV among groups (P = 0.02). The relationship was significantly different between placebo and ET (P = 0.03) and EPT (P = 0.01), respectively, but not between ET and EPT. Additionally, pooled results of active treatments disclosed that SBP, DBP, PWV, and augmentation index at the aorta were significantly reduced relative to baseline. CONCLUSIONS: There was no difference in ambulatory BP between ET and EPT in postmenopausal Korean women with grade 1 hypertension. Further, ET and EPT similarly decreased baPWV from baseline as compared with placebo. MP4 might not adversely influence estrogen effects on ambulatory BP and arterial stiffness.

Post-operative cyclic oral contraceptive use after gonadotrophin-releasing hormone agonist treatment effectively prevents endometrioma recurrence.

BACKGROUND: Currently, no standard post-operative medical therapy has been shown to be superior in reducing the recurrence of endometrioma. This retrospective study was performed to evaluate the efficacy of post-operative cyclic oral contraceptive (OC) use after GnRH agonist (GnRHa) treatment for the prevention of endometrioma recurrence. METHODS: This retrospective study included 362 reproductive-aged patients who had undergone pelviscopic surgery for endometrioma. Patients were divided into two groups: a group that received cyclic, low-dose, monophasic OCs after GnRHa treatment (n = 175) and a group that received only GnRHa treatment (n = 187). Endometrioma recurrence was evaluated by an ultrasound. RESULTS: During the follow-up period (median, 35 months; range, 12-114 months), recurrent endometriomas were detected in 67 patients (18.5%). Patients receiving cyclic OCs after GnRHa treatment showed a significantly reduced recurrence risk of endometrioma, when compared with patients receiving GnRHa alone (odds ratio = 0.20; 95% confidence interval, 0.10-0.38). The cumulative proportion of recurrent endometrioma after 60 months was significantly lower in OC users than in non-users (6.1 versus 43.3%; P < 0.001), and a statistically significant difference was first detected at 30 months of follow-up (5.1 versus 17.1%; P = 0.018). The number of GnRHa injections (3 versus 6) did not affect the recurrence rate for up to 60 months in OC non-users or users. CONCLUSIONS: Post-operative cyclic OC use after GnRHa treatment effectively reduces the recurrence of endometrioma.

Estrogen receptor {alpha} gene polymorphisms in patients with idiopathic premature ovarian failure.

BACKGROUND: It has been reported that polymorphisms in the estrogen receptor (ER)-alpha gene (ESR1) may be associated with reproductive patterns of women. This study was performed to investigate whether the genetic polymorphisms of the ER-alpha gene are associated with idiopathic premature ovarian failure (POF) in a Korean population. METHODS: The subjects were 126 idiopathic POF patients and 221 post-menopausal controls recruited from university hospitals between 1999 and 2004. Genotyping was performed by MGB primer/probe Taqman assay. Haplotypes were deduced by using the Haploview version 4.1. Bonferroni correction was applied for the correction of multiple testing. RESULTS: There was no significant difference in the allele distribution of the ER-alpha gene (TA)n repeats between the POF and the control group. For the PvuII polymorphism, the POF group showed a higher frequency of TT genotype compared with the controls (41.3 versus 26.3%, P = 0.004, 98.75% CI 1.8-28.2%). No significant difference was found in the distribution of the XbaI polymorphism between the POF and the control group. Haplotype analysis showed that the frequency of TA haplotype was significantly higher in the POF patients compared with the controls (64.7 versus 52.7%, P = 0.002, 98.75% CI 2.4-21.6%). CONCLUSIONS: These findings suggest that the ER-alpha gene polymorphisms may be associated with idiopathic POF.

Reproductive health characteristics of urban South Korean women.

AIMS: To characterize the reproductive health of urban South Korean women of reproductive age. METHODS: A cross-sectional online survey on menstrual patterns, sexual behavior, utilization of contraception, and perception of gynecological diseases was administered to 500 women from 15 to 39 years of age in five major cities of South Korea. RESULTS: Among the respondents, 76.8 and 25% experienced dysmenorrhea and abnormal uterine bleeding, respectively. Two-thirds of the respondents with dysmenorrhea used analgesics. After analgesics, herbal medicine was the next most commonly used treatment. The mean age of first sexual intercourse was 24.3 years, and 68.8% of the sexually active women used contraception. The most commonly used contraceptive method was the condom (79.7%), and many women (up to 62.2%) demonstrated a distorted understanding of oral contraceptives. Although many women were aware of general gynecological diseases such as cervical cancer (77%), endometriosis (64.4%), and leiomyoma (62.6%), only 22.2% of the respondents had visited a clinic for a gynecological examination, and among those who had visited a clinic, the main reason for the visit was pregnancy (44.1%). CONCLUSION: The results of this survey provide insight into and allow us to characterize the reproductive health status of urban South Korean women.

GnRH agonist therapy to protect ovarian function in young Korean breast cancer patients.

The increased survival of patients with breast cancer has given rise to other problems associated with the complications of chemotherapy. One major complication is premature ovarian failure, an especially harmful outcome for women of reproductive age. This study was performed to evaluate the efficacy of GnRH agonist (GnRHa) treatment on protecting ovarian function in young breast cancer patients (30.59+/-5.1 yr) receiving chemotherapy after surgery. Twenty-two women were enrolled and given subcutaneous injections of leuprolide acetate (3.75 mg) every 4 weeks during chemotherapy. Follow-up laboratory tests (luteinizing hormone [LH], follicle stimulating hormone [FSH], and estradiol) were performed 1, 3, and 6 months after chemotherapy. Menstruation patterns and clinical symptoms were followed up for a mean duration of 35.6+/-1.7 months. FSH and LH levels were normal in all patients 6 months after completing chemotherapy (8.0+/-5.3, 4.4+/-2.7 mIU/mL, respectively). During follow-up, none of the patients complained of menopausal symptoms and 81.8% experienced recovery of menstruation. This report is the first trial of GnRHa as a treatment modality to protect ovarian function during adjuvant chemotherapy in young Korean breast cancer patients.

Determination of an applicable FRAX model in Korean women.

We investigated which of the three FRAX fracture risk assessment tool models is most applicable to Korean women. For 306 postmenopausal women (mean age, 77 yr) with a hip fracture, fracture probabilities were calculated using FRAX models from Japan, Turkey and China. Data on bone mineral density (BMD) at the femoral neck were available for 103 patients. Significant differences existed among the models, independent of the inclusion of BMD in the calculation of fracture probabilities. The probabilities of both major osteoporotic fractures and hip fractures were significantly higher in the Japanese model than in the Turkish or Chinese models. In all of the models, the probabilities of a major osteoporotic fracture, but not of a hip fracture, decreased significantly if calculated without BMD values. By applying the Japanese model, the ten-year probabilities for major osteoporotic and hip fractures increased significantly with age. Our results suggest that the Japanese FRAX model might be the most appropriate for Korean women.
