Uterine bleeding is a physiologic monthly event occuring during the reproductive period of the nonpregnant woman. As with any other physiologic event, normal women have different menstrual patterns and at times, it is difficult to define when normality ends and abnormality begins. Dysfunctional uterine bleeding is an all-inclusive term: its diagnosis usually bepends on the exclusion of local or systemic organic causes. The term dysfunctional refers to alterations in the physiologic mechanism controlling a multitude of cyclic events in the women's reproductive function. These mechanism are primarily neuroendocrine in nature. According to oriental medicine, the Metrorrhagia(崩漏) means an abnormal bleeding of femail genetalia, and is devided to bungjung and bungha. The etiological factors of metrorrhagia are heat of blood, asthenic coldness, asthenia of chong and ren channels, deficiency of blood, deficiency of vital energy, stagnated blood, and asthenia of spleen & stomach.

Following intracoronary stenting, antiplatelet therapy lead to greater protection from thrombotic complication. A few data are available about the effect of clopidogrel versus cilostazol, an antiplatelet commonly used after intracoronary stenting. To evaluate the efficacy and safety of clopidogrel plus aspirin compared with those of cilostazol plus aspirin in coronary stenting and to evaluate the efficacy of clopidogrel loading dose prior to coronary stealing in clopidogrel group. Data were retrospectively collected from medical charts of patients who had undergone coronary stenting and received either clopidogrel with or without loading 300 mg followed by 75 mg/d (n=58), or 200 mg/d cilostazol(n=72) for 1 year, between January 2000 and May 2002. All patients in both groups received aspirin 200 mg/d throughout the study. The primary endpoints at 7, 30, 180 and 365 days after stealing were the composite of death, Myocardial Infarction, stroke, angina, and revascularization in the intent to treat population and restenosis at follow up angiography. The secondary endpoints were the incidence of bleeding complications at 7, 30, and 365 days, and durg adverse effects at 365 days after stenting. At 180 and 365 days after stenting, the combined primary endpoints were significantly reduced in clopidogrel plus aspirin group (relative risk 0.39; 95% CI 0.17 to 0.92; p=0.021, RR 0.43; 95% CI 0.22 to 0.84; p=0.0085, respectively). However, the combined primary endpoints were not significantly different between the two groups at 7 and 30 days (p:1.00, p=0.79, respectively). Angiographic restenosis rate was 14.3% in clopidogrel plus aspirin uoup and 32.1% in cilostazol plus aspirin group (p=0.19). 300mg of clopidogrel loading dose did not significantly reduce the combined primary endpoints at 30 days after stenting (RR 0.14; 95% CI 0.01 to 2.65; p=0.23). The rate of bleeding complications and drug adverse effects were not different between the two groups. In patients undergoing intracoronary stenting, clopidogrel plus aspirin therapy is more beneficial than cilostazol plus aspirin in reducing major adverse cardiac events with similar rate of bleeding complication. A loading dose of clopidogrel did not lead to a statistically significant reduction in major adverse cardiac events.

Purpose: Tumor bleeding is a major complication in inoperable gastric cancer. The study aim was to investigate the effects of proton pump inhibitor (PPI) treatment for the prevention of gastric tumor bleeding. Materials and Methods: This study was a prospective double-blind, randomized, placebo-controlled trial. Patients with inoperable gastric cancer were randomly assigned to receive oral lansoprazole (30 mg) or placebo daily. The primary endpoint was the occurrence of tumor bleeding, and the secondary endpoints were transfusion requirement and overall survival (OS). Results: This study initially planned to enroll 394 patients, but prematurely ended due to low recruitment rate. Overall, 127 patients were included in the analyses: 64 in the lansoprazole group and 63 in the placebo group. During the median follow-up of 6.4 months, tumor bleeding rates were 7.8% and 9.5%, in the lansoprazole and placebo groups, respectively, with the cumulative bleeding incidence not statistically different between the groups (P=0.515, Gray's test). However, during the initial 4 months, 4 placebo-treated patients developed tumor bleeding, whereas there were no bleeding events in the lansoprazole-treated patients (P=0.041, Gray's test). There was no difference in the proportion of patients who required transfusion between the groups. The OS between the lansoprazole (11.7 months) and the placebo (11.0 months) groups was not statistically different (P=0.610). Study drug-related serious adverse event or bleeding-related death did not occur. Conclusions: Treating patients with inoperable gastric cancer with lansoprazole did not significantly reduce the incidence of tumor bleeding. However, further studies are needed to evaluate whether lansoprazole can prevent tumor bleeding during earlier phases of chemotherapy (ClinicalTrial.gov, identifier No. NCT02150447).

Background: This study was conducted to evaluate the safety and efficacy of left atrial appendage (LAA) excision using a vascular stapler. Methods: Fifty consecutive patients (mean age, 68±9 years) who underwent LAA excision using a vascular stapler during concomitant cardiac surgery were enrolled. In all patients, the excision site was evaluated using computed tomography at a median of 7 days (interquartile range, 5-13.3 days) postoperatively. The safety endpoint of this study was the occurrence of LAA excision-related events, which were defined as bleeding from the excision site that required reinforcement sutures or reoperation due to excision site bleeding. The efficacy endpoint was LAA excision failure, which was defined as a remnant LAA (a stump >1 cm in maximum length) or extravasation of radiocontrast dye. Results: LAAs were excised using 60- and 45-mm vascular staplers in 49 patients and 1 patient, respectively. Reinforcement sutures were needed in 4 patients due to staple-line bleeding and in 4 patients due to bleeding of the surrounding tissues. No patient underwent reoperation due to staple-related bleeding. A remnant LAA was observed in 2 patients, while extravasation of radiocontrast dye was not observed in any patients. Conclusion: LAA excision using a vascular stapler may be an effective technique for LAA exclusion. Delicate handling of the stapler device and LA tissue is required to prevent procedure-related complications.

Purpose: This systematic review and meta-analysis aimed to compare endoscopy as primary versus secondary prophylaxis to prevent future bleeding in children with esophageal varices. Methods: A systematic literature search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was conducted using the Scopus, PubMed, and Cochrane databases for relevant studies on the outcome of rebleeding events after endoscopy in primary prophylaxis compared to that in secondary prophylaxis. The following keywords were used: esophageal varices, children, endoscopy, primary prophylaxis and bleeding. The quality of eligible articles was assessed using the Newcastle-Ottawa Scale and statistically analyzed using RevMan 5.4 software. Results: A total of 174 children were included from four eligible articles. All four studies were considered of high-quality based on the Newcastle-Ottawa Quality Assessment Scale. Patients who received primary prophylaxis had 79% lower odds of bleeding than those who received secondary prophylaxis (odds ratio, 0.21; 95% confidence interval [CI], 0.07-0.66; I²=0%, p=0.008). Patients in the primary prophylaxis group underwent fewer endoscopic procedures to eradicate varices than those in the secondary prophylaxis group, with a mean difference of 1.73 (95% CI, 0.91-2.56; I²=62%, p<0.0001). Conclusion: Children with high-risk varices who underwent primary prophylaxis were less likely to experience future bleeding episodes and required fewer endoscopic procedures to eradicate the varices than children who underwent secondary prophylaxis.

Objectives: To evaluate the effectiveness and safety of traditional herbal medicine (THM) in the treatment of dysfunctional uterine bleeding (DUB) versus conventional western medicine. Methods: Randomized Controlled Trials (RCTs) comparing THM vs. conventional western medicine for DUB, were obtained from PubMed, Cochrane Library, Embase, CNKI, RISS, NDSL, KISS and OASIS. The risk of bias was assessed by using Cochrane's risk of bias tool. Results: 16 RCTs with 1,659 patients were identified and reviewed. 10 RCTs reported THM was statistically effective than control group in effective rate. Also recurrent rate was estimated in 6 RCTs and was lower than control group. 7 studies observed adverse events (AEs) and severe AEs were not reported. Conclusions: Despite several limitations, this review suggested that THM was safe and effective in the treatment of DUB. THM may also decrease the recurrence rate. However, this could not be proven conclusively. To ensure evidence-based clinical practice, more sternly designed trials are warranted.

Homozygous familial hypercholesterolemia (HoFH) is a rare inherited disorder that presents as abnormally elevated levels of low-density lipoprotein cholesterol and premature heart disease, requiring frequent intervention through lipid apheresis for management. The risk of perioperative cardiac events is higher in patients with HoFH because of its pathophysiological manifestations in the vascular system. Careful cardiac precautions and anesthetic assessments are necessary to ensure patient safety. In the following case report, we discuss the clinical course and anesthetic considerations for a 14-year-old girl with HoFH undergoing sedation for dental extractions and mandibular molar uprighting in an outpatient oral surgery clinic. Considerations included the use of heparin in the patient's weekly plasma lipid apheresis treatment. In order to reduce the risks of peri- and postoperative bleeding and perioperative cardiac events, the operation was scheduled for 4 days after apheresis. This allowed for adequate heparin clearance, while also reducing the likelihood of possible cardiac events. A literature review revealed no results for the outpatient management of patients with HoFH undergoing sedation for noncardiac procedures. Our reported case serves as a clinical example for physicians to be utilized in the future.

Background: Although aortic valve repair can reduce prosthesis-related complications, rheumatic aortic regurgitation (AR) caused by leaflet restriction is a significant risk factor for recurrent AR. In this study, we evaluated the long-term results of the leaflet extension technique for rheumatic AR. Methods: Between 1995 and 2016, 33 patients underwent aortic valve repair using the leaflet extension technique with autologous pericardium for rheumatic pure AR. Twenty patients had severe AR and 9 had combined moderate or greater mitral regurgitation. Their mean age was $32.2{\pm}13.9$ years. The mean follow-up duration was $18.3{\pm}5.8$ years. Results: There were no cases of operative mortality, but postoperative complications occurred in 5 patients. Overall survival at 10 and 20 years was 93.5% and 87.1%, respectively. There were no thromboembolic cerebrovascular events, but 4 late deaths occurred, as well as a bleeding event in 1 patient who was taking warfarin. Twelve patients underwent aortic valve reoperation. The mean interval to reoperation was $13.1{\pm}6.1$ years. Freedom from reoperation at 10 and 20 years was 96.7% and 66.6%, respectively. Conclusion: The long-term results of the leaflet extension technique showed acceptable durability and a low incidence of thromboembolic events and bleeding. The leaflet extension technique may be a good option for young patients with rheumatic AR.

Background: A previous percutaneous coronary intervention (PCI) may affect the outcomes of patients who undergo coronary artery bypass grafting (CABG). The objective of this study was to compare the early in-hospital postoperative outcomes between patients who underwent CABG with or without previous PCI. Methods: The present study included 160 patients who underwent isolated elective on-pump CABG at the department of cardiothoracic surgery, Minia University Hospital from January 2010 to December 2014. Patients who previously underwent PCI (n=38) were compared to patients who did not (n=122). Preoperative, operative, and early in-hospital postoperative data were analyzed. The end points of the study were in-hospital mortality and postoperative major adverse events. Results: Non-significant differences were found between the study groups regarding preoperative demographic data, risk factors, left ventricular ejection fraction, New York Heart Association class, EuroSCORE, the presence of left main disease, reoperation for bleeding, postoperative acute myocardial infarction, a neurological deficit, need for renal dialysis, hospital stay, and in-hospital mortality. The average time from PCI to CABG was $13.9{\pm}5.4$ years. The previous PCI group exhibited a significantly larger proportion of patients who experienced in-hospital major adverse events (15.8% vs. 2.5%, p=0.002). On multivariate analysis, only previous PCI was found to be a significant predictor of major adverse events (odds ratio, 0.16; 95% confidence interval, 0.03 to 0.71; p=0.01). Conclusion: Previous PCI was found to have a significant effect on the incidence of early major adverse events after CABG. Further large-scale and long-term studies are recommended.
