We report a 77-year-old woman who underwent mitral valve repair using leaflet folding plasty for mitral regurgitation due to bilatelal commissural prolapse. A Carpentier prosthetic ring was applied to remodel the annulus and to reinforce repair. Postoperative echocardiography revealed no regurgitation and good mitral valve opening. Leaflet folding plasty is considered to be a simple and effective technique to accomplish mitral valve repair for mitral regurgitation due to commissural prolapse.

The purpose of this study was to analyze the body characteristics of university soccer players, especially the hip joint and pelvis where chronic injuries frequently occur among soccer players.
Body characteristics of seventy male university soccer players were surveyed by an orthopedic medical check. The Micro FET value (MF) was used as the unique test for the potential stress on the pubic symphysis. MF was defined as the pressure value at which a subject claimed tenderness from compression on the pubic symphysis.
Among the various tests of the orthopedic medical check, trunk extension in the prone position and external rotation of the hip joint in the standing position correlated with MF. The same tendencies were observed in soccer players with pubic symphysitis.
Results indicate that these three simple tests : MF, trunk extension in the prone position and external rotation of the hip joint in the standing position, can be used as valuable indices for detecting pubic symphysitis in the early stages.

We reviewed 223 cases of surgical treatment for abdominal aortic aneurysm in octogenarians in this hospital between 1981 and 2000, and investigated the characteristic features, complications, and indications of the operation. The cases were divided into two age groups. Group O included 23 cases of octogenarians, and Group Y included 200 cases of patients under 80 years old. The average age was 68.6 years old in group Y (33-79 years old), and 83 years old in group O (80-93 years old). The hospital mortality rate was 0% in elective operation cases. In emergency operation case, Group O had a hospital mortality rate of 57.1%, significantly higher than the 6.1% for group Y. The hospital mortality rate was 17% in group O and 0.5% in group Y. The rate of emergency operation case was significantly higher in group O (30.4%) compared to group Y (16.5%). As for the preoperative complications, group O had more cases of renal dysfunction, COPD and gastrointestinal complication. As for the coronary artery disease and other cardiovascular complications, there were no significant differences between the groups. In the postoperative complication, group O had more cases of ileus, pneumonia, and cardiovascular disease. These complications were fatal in group O. These results suggest that surgical treatment for abdominal aortic aneurysm was performed safely in both groups for elective operations. Because the results of emergency operations are poor, early diagnosis and treatment seem to be important for the improvement of operative results.

The approach for the heart and proximal aorta in a patient with a tracheostomy poses difficult problems such as mediastinitis and inadequate operative exposure. We report a case of successful surgical treatment for type A aortic dissection in a patient with tracheostomy using a Y shaped skin incision and median full-sternotomy. A 63-year-old woman with a tracheostomy was referred to our hospital because of type A thrombosed aortic dissection and cardiac tamponade. At first we treated the patient conseservatively, but follow-up CT taken on the 20th day after onset revealed that false lumen of the ascending aorta was patent and the size of ascending aorta had increased to 6cm in diameter. We therefore performed hemiarch replacement (24mm Hemashield gold graft) through a Y shaped skin incision and median full-sternotomy. The postoperative course was uneventful and she was discharged on the 19th postoperative day.

Purpose: Escitalopram has been inadequately evaluated in cancer patients. Here, we report two patients with advanced cancer who benefited from escitalopram for depression. Case 1: A man aged in his 50s had postoperative recurrence of rectal cancer. He was diagnosed with a major depressive episode according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). The score of the Hamilton Rating Scale for Depression (HAMD-17) was 20 points. He began treatment with 10 mg/day of escitalopram. His symptoms began to improve at about 14 days, and the HAMD-17 score was 4 points at 23 days, suggesting a marked improvement. Case 2: A woman aged in her 50s had cancer of the external auditory canal. She was diagnosed with a major depressive episode according to DSM-IV-TR. The score of HAMD-17 was 26 points. She began treatment with 10 mg/day of escitalopram. Her symptoms began to improve at 15 days, and the HAMD-17 score at 28 days was 13 points, suggesting a marked improvement. In both cases, serious side effects, clear exacerbation of depression, and withdrawal syndrome due to acute drug deprivation associated with worsening of the symptoms were not noted. Conclusion: Escitalopram is considered a useful drug for depression in patients with advanced cancer.

When patients hospitalized in a palliative care unit die, particularly when their deaths were not peaceful ones, we, as health professionals, feel distressed, senses of helplessness and defeat, and even regret. However, busy daily clinical practice usually does not allow us to express these feelings. After going through such an experience repeatedly, your self-efficacy may be reduced and you could feel burned out. In this study, through the experience of coping with the death of a liver cancer patient who died of necrotizing fasciitis resulted from bedsore, a death conference was organized for us, health professionals who had been directly concerned with the patient, to discuss questions, conflicts, and dilemmas that arose when we provided care and express feelings that had been repressed. And other participants in the conference, who had not been directly concerned with the patient, gave their affirmative views. The conferences served to: (1) promote mutual understanding, trustful relationships, and teamwork among us, (2) increase our awareness of palliative care, and (3) allow us to cope with stress and prevent us from feeling burned out. These effects are considered to help implement improved health care. In the former part of the conference remarks were divided into three categories, (1) regret, (2) questions, conflicts, and dilemmas, and (3) senses of helplessness and defeat, and in the latter part affirmative views were mainly stated.

BACKGROUND: Increased triglycerides (TGs) and decreased high density lipoprotein cholesterol (HDL-C) levels are established as diabetic risks for nondiabetic subjects. The aim of this study was to investigate the relationship among TG, HDL-C, TG/HDL-C ratio, and early-phase insulin secretion in normoglycemic and prediabetic subjects. METHODS: We evaluated 663 Japanese subjects who underwent the 75-g oral glucose tolerance test. On the basis of these results, the subjects were divided into four groups: those with normal glucose tolerance (NGT; n=341), isolated impaired fasting glucose (i-IFG; n=211), isolated impaired glucose tolerance (i-IGT; n=71), and combined IFG and IGT (IFG+IGT; n=40). Insulin secretion was estimated by the insulinogenic index (IGI) (Deltainsulin/Deltaglucose [30 to 0 minutes]) and disposition index (DI) (IGI/homeostasis model assessment of insulin resistance). RESULTS: In prediabetic subjects (i-IFG, i-IGT, and IFG+IGT), linear regression analyses revealed that IGI and DI were positively correlated with HDL-C levels. Moreover, in subjects with i-IGT and (IFG+IGT), but not with i-IFG, the indices of insulin secretion were negatively correlated with the log-transformed TG and TG/HDL-C ratio. In both the subjects with i-IGT, multivariate linear regression analyses revealed that DI was positively correlated with HDL-C and negatively with log-transformed TG and TG/HDL-C ratio. On the other hand, in subjects with NGT, there was no association between insulin secretion and lipid profiles. CONCLUSION: These results revealed that serum TG and HDL-C levels have different impacts on early-phase insulin secretion on the basis of their glucose tolerance status.

Mycoplasma spp. are contagious bacteria, and mycoplasmal mastitis is a serious productivity problem on dairy farms. Bovine mammary epithelial cells (bMECs) have an important role in the elimination of pathogens, but the effect of Mycoplasma bovis on bMECs has not been fully described. To elucidate the immune response against intramammary infection by M. bovis, we undertook microarray analysis to examine and profile mRNA expression in bMECs after stimulation with M. bovis. We also compared the effects of M. bovis, Staphylococcus aureus, and Escherichia coli on immune-related mRNA expression in bMECs. Transcriptome analysis indicated a significant decrease in the level of mRNA-encoding lysine-specific demethylase 4D, suggesting that the immune response is suppressed by a decrease in histone demethylase activity. Interleukin (IL)-1β, IL-6, tumor necrosis factor alpha, toll-like receptor (TLR) 2, and TLR4 mRNA expression levels were significantly increased in bMECs stimulated with heat-killed M. bovis, but the expression levels were lower than those following stimulation by heat-killed S. aureus or E. coli. Our results suggest that M. bovis weakly affects mRNA expression in bMECs compared to the effects of E. coli or S. aureus. Moreover, live M. bovis may induce suppression of the immune response in bMECs.

BACKGROUND/AIMS: There are few reports on the correlation between chewing gum and the gastrointestinal functions. But previous report showed use of chewing gum to be an effective method for controlling gastrointestinal symptoms. The aim of this study was to determine the correlation between chewing gum and gastric emptying using the continuous real time 13C breath test (BreathID system). METHODS: Ten healthy male volunteers participated in this randomized, 2-way crossover study. The subjects fasted overnight and were randomly assigned to chewing gum (Xylish, 2-3/1 tablet) for an hour following intake of a test meal (200 kcal/200 mL) or intake of the test meal alone. Gastric emptying was monitored for 4 hours after administration of the test meal by the 13C-acetic acid breath test performed continually using the BreathID system. RESULTS: No significant differences in the calculated parameters, namely, T1/2 (median, 111.82 vs 109.26 minutes; P = 0.575), Tlag (median, 53.28 vs 56.53 minutes; P = 0.333), gastric emptying coefficient (median, 3.58 vs 3.65; P = 0.285), regression-estimated constant beta (median, 1.85 vs 1.80; P = 0.575) and regression-estimated constant kappa (median, 0.61 vs 0.62; P = 0.959) were observed between the test meal alone group and the test meal and chewing gum group. CONCLUSIONS: This study showed that chewing gum had no effect on the rate of gastric emptying. Therefore, since chewing gum did not enhance the speed of gastric emptying, it may ameliorate gastrointestinal symptoms through other mechanisms, such as saliva and autonomic nervous system.

BACKGROUND/AIMS: The gastrointestinal motility effects of endogenous incretin hormones enhanced by dipeptidyl peptidase-IV (DPP-IV) inhibitors have not yet been sufficiently investigated. The aim of this study was to determine whether single pre-prandial sitagliptin, the DPP-IV inhibitor, administration might have an effect on the rate of liquid gastric emptying using the 13C-acetic acid breath test. METHODS: Ten healthy male volunteers participated in this randomized, two-way crossover study. The subjects fasted for overnight and were randomly assigned to receive 50 mg sitagliptin 2 hours before ingestion of the liquid test meal (200 kcal per 200 mL, containing 100 mg 13C-acetate) or the test meal alone. Under both conditions, breath samples were collected for 150 minutes following the meal. Liquid gastric emptying was estimated by the values of the following parameters: the time required for 50% emptying of the labeled meal (T1/2), the analog to the scintigraphy lag time for 10% emptying of the labeled meal (Tlag), the gastric emptying coefficient and the regression-estimated constants (beta and kappa), calculated by using the 13CO2 breath excretion curve using the conventional formulae. The parameters between the 2 test conditions were compared statistically. RESULTS: No significant differences in the calculated parameters, including T1/2, Tlag, gastric emptying coefficient or beta and kappa, were observed between the 2 test conditions. CONCLUSIONS: The present study revealed that single-dose sitagliptin intake had no significant influence on the rate of liquid gastric emptying in asymptomatic volunteers.
