Background: Female infertility is a crucial problem with significant implications for individuals and society. In this study, we explore risk factors for infertility in Korean women. Methods: A total of 986 female patients who visited six major infertility clinics in Korea were recruited from April to December 2014. Fertile age-matched controls were selected from two nationwide survey study participants. Conditional logistic regression after age-matching was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of each risk factor for infertility. Results: Women with a body mass index (BMI) < 18.5 kg/m2 had 1.35 times higher odds of infertility (OR, 1.35; 95% CI, 1.03–1.77), while those with a BMI ≥ 25.0 kg/m2 had even higher odds (OR, 2.06; 95% CI, 1.61–2.64) compared to women with a normal BMI (18.5 kg/m2 ≤ BMI < 25 kg/m 2 ). Ever-smokers exhibited 4.94 times higher odds of infertility compared to never-smokers (95% CI, 3.45–8.85). Concerning alcohol consumption, women who consumed ≥ 7 glasses at a time showed 3.13 times significantly higher odds of infertility than those who consumed ≤ 4 glasses at a time (95% CI, 1.79–5.48). Lastly, women with thyroid disease demonstrated 1.44 times higher odds of infertility compared to women without thyroid disease (95% CI, 1.00–2.08). Conclusion Female infertility in Korea was associated with underweight, obesity, smoking, alcohol consumption, and thyroid disease.

Methods: We used 1.0-mm interval computed tomographic scan images of 100 patients (50 men and 50 women) and screw trajectory simulation software. The diameter of all screws was set at 3.5 mm, considering its common usage in real surgery. The anatomical feasibility of placing both pedicle and laminar screws on the same side was evaluated. For all feasible sides, the three-dimensional distance between the screw entry points was measured. Results: In 85% of cases, both pedicle and laminar screws could be placed on both sides, allowing for the insertion of 4 screws. In 11% of cases, 2 screws could be placed on one side, while only 1 screw was feasible on the other side, resulting in the placement of 3 screws. In all 181 sides where both types of screws could be inserted, the distance between their entry points exceeded 16.1 mm, which was sufficient to prevent the collision between the screw heads. Conclusions C2 vertebra can accommodate three (11%) or four (85%) screws in 96% of cases.

OBJECTIVES: There is a great deal of interest in the possibility that environmental factors may influence the risk of developing allergic rhinitis (AR) in early life. We investigated the simultaneous effects of mode of delivery and duration of breastfeeding on the development of AR in children. METHODS: Data from 1,374 children participating in the Allergic Rhinitis Cohort Study for kids (ARCO-kids study) was analyzed. All subjects were divided into AR or non-allergic rhinitis (NAR) groups. Data on environmental factors, mode of delivery and duration of breastfeeding were collected using a questionnaire. RESULTS: Compared with short-term breastfeeding (<6 months), long-term breastfeeding (≥12 months) was significantly associated with a lower prevalence of AR (adjusted odds ratio [aOR], 0.54; 95% confidence interval [CI], 0.34 to 0.88). Children in the AR group also had a higher cesarean delivery rate than those in the NAR group (39.1% vs. 32.8%, P=0.05). Regarding the combined effects of mode of delivery and duration of breastfeeding, long-term breastfeeding with a vaginal delivery strongly suppressed the development of AR, compared to short-term breastfeeding with a cesarean delivery (aOR, 0.47; 95% CI, 0.30 to 0.73). CONCLUSION: Long-term breastfeeding (≥12 months) and a vaginal delivery are associated with a lower risk of developing childhood AR.

This workshop was held on July 31-August 1, 2010 and was organized to promote the academic environment and to enhance the communication among Asian countries prior to the 2nd biennial meeting of Australian Society of Gynaecologic Oncologists (ASGO), which will be held on November 3-5, 2011. We summarized the whole contents presented at the workshop. Regarding cervical cancer screening in Asia, particularly in low resource settings, and an update on human papillomavirus (HPV) vaccination was described for prevention and radical surgery overview, fertility sparing and less radical surgery, nerve sparing radical surgery and primary chemoradiotherapy in locally advanced cervical cancer, were discussed for management. As to surgical techniques, nerve sparing radical hysterectomy, optimal staging in early ovarian cancer, laparoscopic radical hysterectomy, one-port surgery and robotic surgery were introduced. After three topics of endometrial cancer, laparoscopic surgery versus open surgery, role of lymphadenectomy and fertility sparing treatment, there was a special additional time for clinical trials in Asia. Finally, chemotherapy including neo-adjuvant chemotherapy, optimal surgical management, and the basis of targeted therapy in ovarian cancer were presented.

A conference was convened by the Korean Diabetes Association and the Korean Endocrine Society on September 7, 2009 to discuss and organize the results of research on intensive glucose control for the prevention of cardiovascular disease in patients with type 2 diabetes. Professor Kyung Soo Park led the conference, and Professors Kwang Won Kim and Ho Young Son acted as chairmen. Professors Doo Man Kim, Tae Sun Park, and Bong Soo Cha reported on intensive glucose control and diabetic complications, including the UK Prospective Diabetes Study (UKPDS), Diabetes Control and Complication Trial (DCCT) research results, the recently published Action to Control Cardiovascular Risk in Diabetes (ACCORD), Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE), and Veterans Affairs Diabetes Trial (VADT) research, as well as meta-analyses. Professor Jeong-Taek Woo reported on the manuscript written by the committee for the Korean Diabetes Association which dealt with the treatment of diabetes mellitus. Professors Kyung Soo Ko, Joong Yeol Park, Hyun Shik Son, Moon-Kyu Lee, Dong-Won Byun, and Yoon-Sok Chung participated in the discussion and collected information for the manuscript from all of the participants. The aim of the debate was to determine how to establish target goals for intensive glucose control and how to individualize those goals. The participants concluded that there was no need to modify the recommendation of maintaining an HbA1c under 6.5%, the current blood glucose treatment goal that is recommended by the Korean Diabetes Association. In addition, individual target goals for glucose control were recommended depending on the situation of each patient. We report on the consensus statement from the meeting.

OBJECTIVES: There is increasing evidence of an association between suicide and psychiatric disorders. This is the first report in Korea that investigated the differences of clinical and demographic characteristics between suicide completers and suicide attempters who had visited emergency room. METHODS: For this study, we enrolled patients who had visited the emergency rooms of university-affiliated medical centers or hospitals, due to psychiatric problems, between January 2003 and December 2006. In October 2007, we used the Korea national statistical office to identify the suicide completers among these enrollees. We then conducted a retrospective chart review comparing clinical and demographic characteristics between suicide attempters and completers. RESULTS: During the study period, 1106 subjects visited the emergency room of a university affiliated medical center or hospital. Among these subjects, the number of suicide attempters and suicide completers was 162 and 13, respectively. The proportion of suicide completion in the suicide related behavior was higher in patients with schizophrenia (27.3%) and anxiety/somatoform disorder (50.0%) compared with those with other psychiatric disorders. Suicide completers used more violent methods of suicide. CONCLUSION: These results suggest that patients with schizophrenia and anxiety/somatoform disorder make more fatal suicide attempts. The proportion of suicide completion within the suicide-related behaviors of these patients was higher than found in other psychiatric disorders. A greater number of risk factors should be elucidated to provide effective suicide prevention programs in Korea.

OBJECTIVES: This study was conducted to investigate the association between the symptoms of boys with attentiondeficit hyperactivity disorder (ADHD) and the attention-deficit hyperactivity symptoms, temperament and character patterns of their parents. METHODS: Forty-five boys with ADHD and who met the DSM-IV criteria were evaluated by using the ADHD rating scale (ADHD-RS), and their parents completed the Korean Adult ADHD scale (K-AADHDS) and the Temperament and Character Inventory (TCI). RESULTS: The parental K-AADHDS scores were not associated with the ADHD-RS total score and the subscale scores of their siblings. The most potent variable related to the ADHD-RS total score was the maternal self-directedness, and the second was the maternal persistence. The maternal self-directedness was the variable that was most correlated with the hyperactivity/impulsivity subscale scores of the ADHD-RS. CONCLUSIONS: The results suggest that the paternal ADHD symptoms may not be related to the ADHD symptoms of boys with ADHD. Higher maternal self-directedness and persistence may decrease overall the ADHD symptoms of these boys, and higher maternal self-directedness itself may predict lower hyperactivity/impulsivity symptoms of the boys with ADHD.

BACKGROUDN: The ratio of mitral inflow (E) and annular velocity (E') to stroke volume (E/E'/SV) has been used as an index of diastolic elastance (Ed). However, its change during exercise has not been evaluated. We hypothesized that Ed values obtained during exercise would be abnormal in patients with apical hypertrophic cardiomyopathy (ApHCM). METHODS: Ed was measured at rest and during graded supine bicycle exercise (25 Watts, 3 minute increments) in 15 patients with ApHCM (12 male; mean age, 57 years) and in 15 age- and gender-matched control subjects. RESULTS: Ed was not significantly different at rest and during 25 W of exercise. However, Ed was significantly higher at 50 W of exercise in patients with ApHCM compared to control subjects (0.21+/-0.05 vs. 0.15+/-0.04 cm/s, p=0.0059). There was significant positive correlation between the magnitude of change in proBNP levels during exercise and the change of Ed from rest to 50 W of exercise (r2=0.69, p<0.0001). CONCLUSION: Noninvasively-determined Ed was similar at rest and during mild exercise between patients with ApHCM and control subjects. However, Ed was significantly higher during moderate exercise in ApHCM patients, suggesting a dynamic change in LV stiffness during exercise in these patients.
