1.Endometriosis and myoma concurrently arising after laparoscopic subtotal hysterectomy.
Korean Journal of Obstetrics and Gynecology 2010;53(12):1136-1140
Iatrogenic endometriosis and leiomyoma are rare complication of laparoscopic subtotal hysterectomy. I experienced a case of pelvic endometriosis and leiomyoma concurrently arising after laparoscopic subtotal hysterectomy 2 years ago. The patient was a 43-year-old woman, and her chief complaint was palpable mass with pelvic pain in pelvis. Contrast-enhanced computed tomography image showed multiple well enhanced masses. She underwent laparoscopic surgery which revealed pelvic endometriosis and leiomyomas. The solid masses in cul-de-sac and on the surface of rectum were revealed endometriosis. The solid masses on the surface of anterior abdominal wall and descending colon were revealed leiomyoma. Implantation of viable endometrial and leiomyoma tissues could occur during uterine morcellation at time of laparoscopic subtotal hysterectomy in some patients. Vigorous irrigation and meticulous inspection should be performed.

2.Recent advance on vitamin D.
Journal of the Korean Medical Association 2013;56(4):310-318
Vitamin D is not only a nutrient, but also a hormone that affects the musculoskeletal system. Recently, extensive attention has been drawn to the autocrine and paracrine functions of vitamin D. Consequently, its extraskeletal effect and its known effects on the skeletal system have drawn particular interest. The socioeconomic development and aging of the population of Korea have also raised interest in dietary supplements. Because vitamin D deficiency is high among Koreans, both physicians and patients are questioning whether vitamin D supplements are needed. This review assessed the skeletal and extraskeletal efficacy of vitamin D with regard to mortality, cancer, cardiovascular disease, and diabetes via an evidence-based approach. The recent interest surrounding vitamin D can be expected to motivate many more studies on its effects and adverse effects, and accordingly, the level of evidence and recommendations will be adjusted. Clinicians should familiarize themselves with updated evidence about vitamin D, and must counsel patients with that evidence in mind.

3.Nutritional supplements.
Journal of the Korean Medical Association 2012;55(9):889-897
A dietary supplement, also known as a food supplement or nutritional supplement, is a preparation intended to supplement the diet and provide nutrients, such as vitamins, minerals, fiber, fatty acids, or amino acids. A health functional food is a food where one or more new ingredients have been added to a food and the new product has an additional function. Physicians and patients need information on current evidence on the efficacy and safety of selected dietary supplements that are commonly used. The current evidence on the efficacy and safety of selected dietary supplements (beta-carotene, vitamin C, D, E, calcium, selenium, omega 3, ginseng, glucosamine, chlorella, saw palmetto, gingko, gamma linolenic acid, echinacea) for specific conditions is assessed by an evidence-based approach. With an increase in income and the aging of the population, spending on dietary supplements is steadily increasing, but concern about the safety and efficacy of dietary supplements may be relatively low. Recently, many domestic and international clinical trials on nutritional supplements have been performed. As a result, the evidence on the efficacy and safety of dietary supplements may be changed or recommendations may also be changed. Greater efforts should be made to acquire the latest knowledge about dietary supplements.

Metabolic syndrome is a cluster of metabolic risk factors associated with increased risk of cardiovascular diseases. Recently, the prevalence of metabolic syndrome has increased in Korea. The aim of this study was to develop a Healthy Han-sik Nutrition Education Program (HHNEP) based on commonly recognized Korean foods in order to decrease metabolic syndrome risks. The target population of the HHNEP is adults with metabolic risk factors. The initial version of the HHNEP was developed based on a review of literature and various dietary guidelines by expert committees as well as the results of a survey on the perception of common Korean dishes and foods as Han-sik. The focus group discussion conducted of nine participants from the target population. After minor modification, the final version was developed. The contents included five sections: 1) aims, 2) introduction of Korean Food Guidance System, 3) cholesterol contents in food, 4) menu planning method using Han-sik, and 5) examples of daily Han-sik menu. The Han-sik list was selected based on the results from a Han-sik perception answered by 35 Korean adults aged 30-60 years using 517 frequently consumed Korean foods from the fourth Korea National Health and Nutrition Examination Survey. The nutrition education program was developed based on scientific evidence for the prevention of metabolic syndrome and focuses on tailoring education to an individual's dietary problems. Educational method was developed by a group of expert committees based in planned behavior theory and related research results. The education method consisted of assessment of current diet, four face-to-face nutrition education sessions over 8 weeks, and evaluation after 8 and 16 weeks. Initial version of nutrition education materials and methods was tested for feasibility by a select group of nine Korean healthy adults. Successful implementation of the program would include application by nutritional professionals at the health promotion center of the hospitals, public health center, and work sites. Intervention studies are needed to evaluate the feasibility and effectiveness of this program before large-scale applications.

Journal of Clinical Neurology 2023;19(1):36-43
Background:
and Purpose This study aimed to determine the ability of deep learning using convolutional neural networks (CNNs) to diagnose transient global amnesia (TGA) based on electroencephalography (EEG) data, and to differentiate between patients with recurrent TGA events and those with a single TGA event.
Methods:
We retrospectively enrolled newly diagnosed patients with TGA and healthy controls. All patients with TGA and the healthy controls underwent EEG. The EEG signals were converted into images using time-frequency analysis with short-time Fourier transforms. We employed two CNN models (AlexNet and VGG19) to classify the patients with TGA and the healthy controls, and for further classification of patients with recurrent TGA events and those with a single TGA event.
Results:
We enrolled 171 patients with TGA and 68 healthy controls. The accuracy and area under the curve (AUC) of the AlexNet and VGG19 models in classifying patients with TGA and healthy controls were 70.4% and 71.8%, and 0.718 and 0.743, respectively. In addition, the accuracy and AUC of the AlexNet and VGG19 models in classifying patients with recurrent TGA events and those with a single TGA event were 71.1% and 88.4%, and 0.773 and 0.873, respectively.
Conclusions
We have successfully demonstrated the feasibility of deep learning in diagnosing TGA based on EEG data, and used two different CNN models to distinguish between patients with recurrent TGA events and those with a single TGA event.

Isolated hypogonadotropic hypogonadism (IHH) is a rare genetic disorder that is clinically and genetically heterogeneous. It is characterized by absent or incomplete pubertal development owing to an isolated defect in the production, secretion, or action of gonadotropin-releasing hormone. The incidence of IHH is estimated at 1:30,000 in males and 1:125,000 in females. Although the vast majority of IHH cases are sporadic, some X-linked recessive, autosomal dominant, and autosomal recessive modes of inheritance have been described. IHH can be classified into Kallmann syndrome with anosmia and normosmic IHH. Here, we report dizygotic twin sisters with normosmic IHH who showed short stature and absence of puberty as a result of a variant of the FGFR1 gene. They had a normal sense of smell, and brain magnetic resonance imaging (MRI) showed well-defined olfactory bulbs. The older sister and the twins' mother had cleft palate, while the younger sister did not. The mother had menarche at the age of 16 years after hormonal replacement owing to delayed puberty. Molecular analysis of the FGFR1 gene identified a missense variant c.874C>G (p.His292Asp) in the twins and their mother. Herein, we described the clinical heterogeneity observed in the 2 affected twins who carry an identical variant in the FGFR1 gene. Further studies of the effects of modifier genes and epigenetic factors on the expression of FGFR1, as well as the various clinical manifestations of its mutations, are warranted.

Metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) are differentiated by the presence of cardiometabolic risk factors (CMRFs) and insulin resistance (IR). This study aimed to evaluate the prevalence and clinical characteristics of MHO in Korean children and adolescents and to investigate the anthropometric, laboratory, and lifestyle predictors of MHO. This study included data from 530 obese subjects, aged 10–19 years, obtained from the Fourth Korea National Health and Nutrition Examination Survey. Subjects were classified into MHO and MUO groups according to the presence of CMRF (MHO(CMRF)/MUO(CMRF)) and degree of IR (MHO(IR)/MUO(IR)). Demographic, anthropometric, cardiometabolic, and lifestyle factors were compared between the groups. Logistic regression analysis and receiver operating characteristic curve analysis were performed to identify factors that predicted MHO. The prevalence of MHO(CMRF) and MHO(IR) in obese Korean youth was 36.8% (n = 197) and 68.8% (n = 356), respectively. CMRF profiles were significantly less favorable in MUO children. Longer and more vigorous physical activity and less protein intake were associated with MHO(CMRF) phenotype. The best predictors of MHO(CMRF) and MHO(IR) were waist circumference (odds ratio [OR], 0.82; 95% confidence interval [CI], 0.77–0.88; P < 0.001) and body mass index (BMI) standard deviation score (OR, 0.24; 95% CI, 0.15–0.39; P < 0.001), respectively. The prevalence of MHO differed depending on how it was defined. To adequately manage obesity in youth, the approach to individuals with MHO and MUO should be personalized due to variation in clinical characteristics. Longitudinal studies are needed to evaluate long-term consequences of MHO.

BACKGROUND: With metabolic syndrome (MS) being a major risk factor for cardiovascular disease, and central obesity being a major predisposing factor for MS, intensive research is currently being performed on cutoff values according to race and sex. Menopause is an especially significant factor in designating cutoff values for female central obesity, as menopause brings sudden bodily changes that induce central obesity and increased prevalence of MS. Therefore this study aimed to investigate the cutoff values for the obesity index and its validity in predicting the criteria for MS in Korean women according to menstrual status. METHODS: The study focused on 3,103 women 20 years of age or older participating in the 2007 Korea National Health and Nutrition Examination Survey. Definitions of non-adipose components of MS were defined by the International Diabetes Federation, and menstrual status was judged on the basis of survey results. The sensitivity, specificity, and positive and negative predictive values of the central obesity index (body mass index [BMI], waist circumference [WC], waist-to-height ratio [WHtR]) according to menstrual status for two or more non-adipose components of MS were calculated based on the Youden index. RESULTS: Area under the curve (AUC) values predicting the presence of two or more metabolic risk factors were higher in pre-menopausal women, with AUC values for BMI, WC, and WHtR being, in pre- and post-menopausal women, 23.1 kg/m2 vs. 23.9 kg/m2, 76.1 cm vs. 82.5 cm, and 0.49 vs. 0.53, respectively. The WC cut off (76 cm) for pre-menopausal women was found to be more sensitive and more effective at screening for MS risks than the cutoff value given by the Korea Society for the Study of Obesity. CONCLUSION: The central obesity index showed better predictability for MS risk in pre-menopausal women. Because the central obesity index cutoff values are lower in pre-menopausal women, the possibility of metabolic risk can be considered for pre-menopausal women with WC lower than 85 cm. Assessment and control of other risks are needed accordingly for preventing the development of MS.

Journal of the Korean Pediatric Society 1998;41(7):953-959
PURPOSE: Leptin is a protein encoded by the ob gene that is expressed in adipocytes. It regulates eating behavior by the action to the satiety centers in the hypothalamus. In ob/ob mouse, adipocytes can not produce leptin because of a mutation in the ob gene which results in obesity. Whereas, leptin concentrations were elevated in obese adults, and leptin levels in obese children has not been studied much until now. The purpose of this study is to evaluate leptin concentrations in obese children and to find out correlating factors with leptin. METHODS: Thirty-six obese childrens whose weight is above 97 percentile of korean weight standard and 39 children with average weight were included. Height, weight, waist to hip ratio, fat weight and lean body mass were measured. The serum levels of leptin, insulin, cholesterol and triglyceride were measured. RESULTS: Mean age was 10.8 +/- 2.5 years in obese group and 10.6 +/- 2.6 years in control group. Obesity percent was 51.6 +/- 18.8% in obese and 8.8 +/- 10.2% in control group. Body mass index (BMI) was 26.3 +/- 5.8kg/m2 in obese group and 17.3 +/- 1.9kg/m2 in control group. Leptin levels of obese group (13.7 +/- 5.4ng/ml) were significantly higher than that of the control group (3.6 +/- 3.3ng/ ml). Leptin levels showed no significant difference by gender and by pubertal development. Leptin levels significantly correlated with BMI, obesity percent, fat weight, and serum cholesterol level but showed no significant correlation with lean body mass, serum fasting insulin and triglyceride levels. CONCLUSION: Serum leptin levels of obesity group were significantly higher than that of the control group, and they were correlated with BMI, obesity percent and fat weight. Additional research is necessary to assess the mechanism of leptin resistance in obese children.
