OBJECTIVES: Dysfunctional uterine bleeding(DUB) is defined as abnormal bleeding from the uterine endometrium unrelated to anatomic lesions of the uterus, and its incidence is 10-15% among gynecologic diseases. We conducted this study for understanding correlation between clinical aspecets and pathological findings of DUB. Methods: We conducted a retrospective review of 599 women with DUB who underwent endometrial biopsy with special regard to the relation between pathologic findings and presenting symtoms or complaints from Jan. 1988 to Dec. 1997. RESULTS: Age distribution of DUB was mainly 5th decade, mean age was 44.1years, among various bleeding patterns, intermenstrual bleeding was the most common pattern(31.6%) and the next was menorrhagia(25.0%). Histologic findings of endometrium were proliferative phase, 327 cases(54.6%), hyperplasia, 139 cases(23.2%), secretory phase, 74 cases(12.4%) in order of frequency, and there was no difference in distribution of histologic findings among various bleeding patterns. CONCLUSION: Compared to other previoius studies, our study showed more incidence of endometrial hyperplasia, especially at age group of 40 or more. So patients aged more than this age with abnormal uterine bleeding must undergo emdometrial biopsy for pathologic diagnosis. Patients who are diagnosed endometrial hyperplasia must be carefully followed up because there are possibilities of progression to endometrial carcinoma.

PURPOSE: The purpose of this study was to investigate the effects of case-based learning (CBL) on learning motivation and learning satisfaction of nursing students in a human physiology course. METHODS: The development and application of CBL scenarios was conducted from February to June, 2013. Nursing students (n=142) who registered for a human physiology course were assigned into either a control or CLB group. The control group received traditional lectures for 14 weeks. The CBL group received the same 14-week lectures and an additional 5 CBL sessions. The learning motivation and satisfaction were measured by questionnaires at the beginning and the end of the semester. Seven students in the CBL group were randomly selected for a focus-group interview. Quantitative data were analyzed by chi2-test and t-test, and qualitative data were analyzed by content analysis. RESULTS: The learning motivation and learning satisfaction were not significantly different between the two groups. However, 59% of the CBL group answered with a positive impression on the CBL approach as it helped them to feel a sense of achievement, excitement, to form their identity as nursing students, and so on. CONCLUSION: These findings suggest that the CBL could be a challenging but useful learning method in a physiology course for nursing students. Further studies with guidance, such as instructors' questions and feedback design are needed to utilize CBL more effectively.

Complications after a median sternotomy incision, which is used currently in most open heart surgery, are serious, although it is infrequent. Reconstruction of the sternal defect resulting from dehiscence of median sternotomy is still big challenge to the most plastic surgeons. Since vascularized greater omentum was transposed to eliminate mediastinal wound problems, many vascularized regional muscle flaps became mainstay in reconstruction of median sternotomy wound. We treated 13 patients with median sternotomy dehiscence between October of 1993 and March of 1998. In two patients, the wound problems were so confined to superficial tissue that debrided and closed primarily. Eleven patients with deep wound infection were managed with vigorous debridement of all necrotic tissues and resultant defects were covered with regional muscle flaps: rectus myocutaneous flap(3) and bilateral pectoralis advancement flap(8). We used the pectoralis major advancement flaps without counter incision at humeral insertion site and the dissections were limited only medial to the anterior axillary line to preserve the axillary fold. In five patients with larger defects, we elevated muscle and cutaneous flaps separately to make these flaps more mobile. Large portion of two rectus abdominis flaps could not survive, whereas pectoralis advancement flaps had mo special wound problems. Only one patient developed fistula due to remained wire, regardless to flap surgery.

PURPOSE: This study examined the factors influencing posttraumatic and conflict management styles for nursing performance in intensive care units (ICUs).METHOD: In this study, 250 nurses from eight general hospitals in three cities participated. Structured self-report questionnaires were used to collect data on posttraumatic, conflict management styles, and nursing performance. Finally, the data were analyzed by SAS 9.3 program.RESULTS: The mean of total sum scores was 31.29, and the high risk of posttraumatic symptoms was 61.2%. It was noted that nursing performance is significantly correlated with collaboration, compromise, accommodation styles, and intrusion. Collaboration styles (β=0.39, p < .001) and hyperarousal (β=−0.22, p=.050), ICU experience below 1 year (β=−0.21, p=.027) and that of 5–10 years (β=−0.19, p=.049), and compromise style (β=0.16, p=.049) were found to be the factors influencing nursing performance with 35.9% explanatory power value of regression model.CONCLUSION: The results of the study reveal that conflict management styles, hyperarousal, and ICU experience are factors predicting the successful performance of ICUs. These findings emphasize the need of developing interventions to reduce stress symptoms and conflicts in ICUs.

Asphyxia is primarily observed in either suicide or homicide. We encountered two unusual autopsy cases, which were extremely rare and atypical, with respect to the manner or cause of death. The first victim demonstrated external findings of a transverse ligature mark around his neck and foreign material in the form of flour or kneaded flour in the whole airway, including the oral and nasal cavity. Based on the scene investigation images and autopsy findings, we identified that the victim attempted to strangle himself with a necktie first, but failed. He then inhaled flour and suffocated. The second victim, who died while sleeping, had a transverse ligature mark around her neck with marked facial congestion, multiple petechia of the conjunctiva and oral mucosa, and extensive hemorrhage of the neck muscles. Police investigation found the deceased stuck in a massage machine without the protective cover that prevents small objects being sucked into the machine. Her death was ruled to be accidental. We present two unusual cases of asphyxia, discuss the mechanism of asphyxia in each case, and review the literature.

Eosinophilic coronary periarteritis (ECPA) is a new type of coronary arteritis. In most cases, it has showed sudden cardiac death due to vasospastic angina or spontaneous coronary artery dissection. Many studies about ECPA have been conducted, but the cause of ECPA has yet to be clarified. ECPA was diagnosed at autopsy and the patients were mainly 30- to 50-year-old man. We report a case of a 50-year-old woman who died from ECPA without spontaneous coronary artery dissection. The autopsy showed a sudden cardiac death and results of microscopic examiniation related to ECPA.

Background: Remimazolam is a novel short-acting benzodiazepine. This study compared the effects of remimazolam and propofol on cognitive function in adult patients after surgery or other procedures. Methods: We searched electronic databases, including PubMed, Embase, CENTRAL, Web of Science, and Scopus, for relevant studies. The primary outcome was the proportion of participants who experienced delirium or impaired cognitive function postoperatively. Secondary outcomes included the incidence of hypotension, bradycardia, and postoperative nausea and vomiting. We estimated the odds ratios (OR) and mean differences (MD) with 95% CIs using a random-effects model. Results: In total, 1295 patients from 11 randomized controlled trials were included. The incidence of postoperative delirium was 8.0% in the remimazolam group and 10.4% in the propofol group that was not significantly different (OR: 0.74, 95% CI [0.39–1.42], P = 0.369, I2 = 32%). More favorable cognitive function, as assessed using the Mini-Mental State Examination, was observed in the remimazolam group compared to the propofol group (MD: 1.06, 95% CI [0.32–1.80], P = 0.005, I2 = 89%). Remimazolam lowered the incidence of hypotension (OR: 0.28, 95% CI [0.21–0.37], P = 0.000, I2 = 0%) compared to propofol. Conclusions Remimazolam did not increase the risk of postoperative delirium and maintained cognitive function well, providing hemodynamic stability during surgery compared to propofol.
