The societies of the world in the 21st century have faced challenges arising from an aging population as the fertility rate has dropped dramatically and medical advances have extended the average human life span. The elderly aged 65 years or older make up at least 20% of the population in Korea, making the country a super-aging society as defined by the United Nations. The number of elderly women is higher than that of elderly men and women live longer than men. Based on the analysis of recent trends in previous studies, this study aimed to suggest practical strategies to utilize isoflavones, substances chemically similar to the female hormone estrogen, and to search for effective anti-aging strategies using this substance for women to be prepared to reach the elderly stage in good health.

From May 1995 to February 1997, 46 patients underwent resectoscopic surgery for infertility. Of 46 patients, 32 patients had uterine synechiae, 5 patients had polyps, 3 patients had septums, 3 patients had bony foreign bodies, 2 patients had submucosal myomas, 1 patient had tuberculous endometritis. The resectoscopic procedure proved of special value for resection of intrauterine adhesion, submucosal myoma, septum and polyp. Except 5 patients, intrauterine conditions were improved and 10 patients were conceived. So it goes without saying that resectoscopic surgery is a effective and acceptable procedure for the management of infertility of endometrial factors. However, with the finding of slightly less satisfactory results with time and number, further follow-up is still needed to establish the usefulness of the procedure.

Adequate maintenance of body temperature during general anesthesia is necessary for safety. Generally, esophageal temperature probe is commonly used in practice for measuring core temperature because of its reliability and feasibility. Proper placement of esophageal temperature probe is important to avoid complications. In this case report, we describe our experience with a patient undergoing lobectomy of the lung in whom the esophageal temperature probe that was misplaced into the right intermediate bronchus was accidentally cut. This case highlights the need to carefully assess correct position of the temperature probe, especially in patients undergoing one-lung ventilation.

Colonic wall thickening is frequently encountered in various conditions, from acute or chronic inflammatory disease to colorectal carcinoma. Colonic wall thickening may be accompanied by calcifications in mucinous adenocarcinoma of the colon, leiomyosarcoma of the colon, schistosomiasis japonica, and phlebosclerotic colitis. Phlebosclerotic colitis is a rare entity of chronic ischemic colitis associated with sclerosis and fibrosis of mesenteric veins. Although its development is usually insidious, and, thus its diagnosis can be delayed, characteristic findings in phlebosclerotic colitis are calcifications of mesenteric veins as well as colonic wall thickening with calcifications. We report on a 71-year-old woman who presented with chronic diarrhea and intermittent hematochezia, who was first misdiagnosed as mucinous adenocarcinoma of the colon, but finally diagnosed as a rare entity of chronic ischemic colitis, phlebosclerotic colitis. Differential points of phlebosclerotic colitis from other diseases, including leiomyosarcoma and schistosomiasis japonica, are also described.

BACKGROUND/AIMS: DA-9701, a standardized extract of Pharbitis Semen and Corydalis Tuber, is a new prokinetic agent that exhibits an analgesic effect on the abdomen. We investigated whether DA-9701 affects visceral pain induced by colorectal distension (CRD) in rats. METHODS: A total of 21 rats were divided into three groups: group A (no CRD+no drug), group B (CRD+no drug), and group C (CRD+DA-9701). Expression of pain-related factors, substance P (SP), c-fos, and phosphorylated extracellular signal-regulated kinase (p-ERK) in the dorsal root ganglion (DRG) and spinal cord was determined by immunohistochemical staining and Western blotting. RESULTS: The proportions of neurons in the DRG and spinal cord expressing SP, c-fos, and p-ERK were higher in group B than in group A. In the group C, the proportion of neurons in the DRG and spinal cord expressing p-ERK was lower than that in group B. Western blot results for p-ERK in the spinal cord indicated a higher level of expression in group B than in group A and a lower level of expression in group C than in group B. CONCLUSIONS: DA-9701 may decrease visceral pain via the downregulation of p-ERK in the DRG and spinal cord.

The number of AIDS patients is currently increasing in Korea, and multiple opportunistic infections, which are due to their immunocompromised state, have become a significant clinical problem. These opportunistic diseases may vary according to the severity of immunosuppression, the mode of transmission, the risk factors, the living environment and treatment; rectal syphilis, perianal condyloma lata and amoebic liver abscess are known to rarely develop in AIDS patients. We report here on a case of a homosexual man who simultaneously presented with an amebic liver abscess, esophageal candidiasis, chronic hepatitis B, rectal syphilis, perianal condyloma lata and asymptomatic neurosyphilis. He was treated with highly active antiretroviral therapy (HARRT) and the appropriate antiviral and antibiotic agents.

Purpose: In young patients with varicocele, preservation of the internal spermatic artery may be advantageous for catch-up growth, but it may also increase the likelihood of treatment failure. Intraoperative venography reduces the likelihood that unsealed veins will remain after varicocelectomy. We analyzed the characteristics of remnant veins visualized through intraoperative venography to investigate the cause of surgical failure in artery-sparing varicocelectomy (ASV). Materials and Methods: We retrospectively analyzed clinical characteristics and outcomes of patients aged 18 years or younger who underwent varicocelectomy with intraoperative venography from January 2005 to December 2017. During varicocelectomy, intraoperative venography was performed to distinguish veins from other structures. Any unsealed veins that were discovered were ligated and classified using the Bähren system. Results: One hundred and sixty-two patients underwent intraoperative venography: 153 cases (94.4%) were for primary varicocelectomy, and 9 cases (5.6%) were for repeat varicocelectomy. Open varicocelectomy was performed in 105 cases (64.8%), and laparoscopic varicocelectomy was performed in 57 cases (35.2%). Venography revealed remnant veins after the first ligation in 51 cases (31.2%), 46 (90.2%) and 5 (9.8%) of which were Bähren types 3 and 4, respectively. Five patients (3.1%) experienced varicocele recurrence, classified as persistence in 1 patient (0.6%) and relapse in 4 patients (2.5%). Conclusion Remnant collateral veins of the internal spermatic vein (ISV) (Bähren type 3) are the most common cause of failure in ASV. In a few patients, an external spermatic vein merges with the ISV at a higher level (Bähren type 4) and is unidentifiable without venography.

The most commonly reported sexual problems in diabetic women are sexual arousal disorder and a lack of vaginal lubrication. The aims of this study were to investigate the vaginal structural changes and expressions of TGF-beta1, Ec-NOS and estrogen receptor alphaby histochemistry, immunohistochemistry and Western blot analysis in diabetic and insulin-treated diabetic rats. The mean blood glucose levels were significantly increased in the diabetic rats (453+/-88.4 mg/dL)compared to the control group (79+/-6 mg/dL)and insulin-treated diabetic rats (56.7+/-0.6 mg/dL).The vaginal wall in control rat showed 6~11 layered stratified squamous epithelial lining and submucosal smooth muscle, connective tissue and vasculatures. In diabetic rat, the vaginal epithelium was reduced to 2~6 layers and the submucosal vasculatures were decreased n size and number.Collagen fibers were increased and irregularly distorted arrangement. Insulin-treated diabetic rat showed similar morphologic features as control rat.In diabetic rat, TGF-beta1 expression was upregulated by 1.65 times and Ec-NOS expression was 40% downregulated compared to control and insulin-treated diabetic rats in Western blot analysis. In control and insulin-treated diabetic rats, TGF-beta1 immunoreactivity was detected in fibroblasts and the collagen fibers, Ec-NOS immunoreactivity in the endothelial cells of blood vessels, and estrogen receptor alphaimmunoreactivity in the basal and intermediate cell layers of stratified squamous epithelium, smooth muscle fibers, and nerve fibers. In diabetic rat, expression of TGF-beta1, Ec-NOS, and estrogen receptor alphawas exhibited comparable cellular patterns of labeling, but signal intensity was increased in TGF-beta1 and decreased in Ec-NOS and estrogen receptor alpha. These results suggest that vaginal tissue fibrosis in diabetes mellitus may be caused by altered expression of TGF-beta1, NOS and estrogen. It also mplies that sexual arousal disorder and lack of vaginal lubrication in the diabetic women could be protected or delayed by controlling blood glucose levels.

BACKGROUND/AIMS: In Asian countries including Korea, the prevalence of gastroesophageal reflux disease (GERD) is on the rise and its clinical impact has been emphasized. The purpose of this study was to investigate the clinical characteristics of esophagitis patients with or without symptoms, and their association with psychological factors. METHODS: Subjects diagnosed as erosive esophagitis of Los Angeles-A or more in screening by upper gastrointestinal endoscopy were enrolled. Questionnaires regarding GERD symptoms and Symptom Checklist-90-Revision were used to identify the presence of psychological symptoms. RESULTS: There was no difference between the subjects' general characteristics (gender, age, body mass index, smoking and alcohol intake) according to the existence of typical symptoms in these patients with erosive esophagitis. Patients with typical GERD symptoms were more likely to have atypical symptoms, dyspepsia and higher scores on psychological symptoms (somatization, obsessive-compulsiveness and phobic anxiety) than those without. CONCLUSIONS: Psychological symptoms and other gastrointestinal symptoms should be considered in the patients with erosive esophagitis.
