A dieulafoy ulcer is rarely recognized but is not an uncommon cause of massive, recurrent and frequently fatal gastrointestinal bleeding resulting from the erosion of an unusually large submucosal artery. Although the lesion has been predominantly found in the proximal stomach, it has also been detected throughout the gastrointestinal tract. Diagnosis can be made by observation of protruding and eroded arteries with pulsatile bleeding, or through detection of an adherent thrombus using an endoscopy. In the past, surgical intervention was believed to be the best treatment, but currently, therapeutic endoscopy is more favored, due to its recent success in achieving permanent hemostasis. We experienced 2 cases of Dieulafoy's ulcer of the stomach. Endoscopic ligations using an O ring were performed successfully.

PURPOSE: Defecography is a dynamic investigation which can influence clinical decision making in patients with pelvic outlet obstructive disease (POOD). The current study was designed to establish defecographic findings in patients with POOD. Specifically, we sought to assess the physiologic characteristics of categorized types by using anorectal physiologic tests. METHODS: One hundred seven patients (disease group; 45 men, 62 women) with POOD were retrospectively categorized as type I [non-relaxation of puborectalis (NRPR) only, n=19], type II [NRPR and rectocele, n=20], type III [NRPR, rectocele, and dynamic perineal descent (PD), n=17], type IV [deformed rectocele, mild-to-moderate fixed PD, and absence of NRPR, n=29], and type V [rectocele, severe fixed PD, and absence of NRPR, n=20] on the bases of defecographic findings. The ability to evacuate, the frequency/degree of intarectal intussusception (IRI), and the size of the rectocele were evaulated in these defecographic types of POOD. Age, duration of symptoms, and the physiologic findings of anal manometry and EMG/PNTML were compared for the five types. Eighteen healthy volunteers who had no defecation difficulty were used to estimate the normal findings of defecography. RESULTS: The age and the sex showed no significant differences among the types. The duration of symptoms was gradually lengthened from type I to V (P<0.01). The ability to evacuate in patients with POOD was significantly worse (failed to effectively evacuate) compared to that in the healthy volunteers (P<0.01). The frequency of IRI was increased more and more from type I to V (P<0.01). The size of the rectocele was significantly increased in types V compared to the other types (P<0.01). Manometric and neurologic findings, including EMG/PNTML, revealed no significant differences among the types. CONCLUSIONS: Even though there were no specific differences in the findings of the anal manometric and neurologic tests, the evacuation dynamics; were different in the five defecographic categories of patients with POOD. Specifically, these differences were relevants to the presence of NRPR, rectoceles, IRI, and perineal descent.

BACKGROUND: Infective endocarditis shows higher operative morbidity and mortality rates than other cardiac diseases. The vast majority of studies on infective endocarditis have been made on aortic endocarditis, with little attention having been paid to infective endocarditis on the mitral valve. This study attempts to investigate the clinical aspects and operative results of infective endocarditis on the mitral valve. METERIAL AND METHOD: The subjects of this study consist of 23 patients who underwent operations for infective endocariditis on the mitral valve from June 1995 to May 2003. Among them, 2 patients suffered from prosthetic valvular endocarditis and the other 21 from native valvular endocarditis. The subjects were evenly distributed age-wise with an average age of 44.8+/-15.7 (11~66) years. Emergency operations were performed on seventeen patients (73.9%) due to large vegetation or instable hemodynamic status. In preoperative examinations, twelve patients exhibited congestive heart failure, four patients renal failure, two patients spleen and renal infarction, and two patients temporary neurological defects, while one patient had a brain abscess. Based on the NYHA functional classification, seven patients were determined to be at Grade II, 9 patients at Grade III, and 6 patients at Grade IV. Vegetations were detected in 20 patients while mitral regurgitation was dominant in 19 patients with 4 patients showing up as mitral stenosis dominant on the preoperative echocardiogram. Blood cultures for causative organisms were performed on all patients, and positive results were obtained from ten patients, with five cases of Streptococcus viridance, two cases of methicillin-sensitive Staphylococcus aureus, and one case each of Corynebacterium, Haemophillis, and Gernella. Operations were decided according to the AA/AHA guidelines (1988). The mean follow-up period was 27.6+/-23.3 (1~97) months. RESULT: Mitral valve replacements were performed on 13 patients, with mechanical valves being used on 9 patients and tissue valves on the other 4. Several kinds of mitral valve repair or mitral valvuloplasty were carried out on the remaining 10 patients. Associated procedures included six aortic valve replacements, two tricuspid annuloplasty, one modified Maze operation, and one direct closure of a ventricular septal defect. Postoperative complications included two cases of bleeding and one case each of mediastinitis, low cardiac output syndrome, and pneumonia. There were no cases of early deaths, or death within 30 days following the operation. No patient died in the hospital or experienced valve related complications. One patient, however, underwent mitral valvuloplasty 3 months after the operation. Another patient died from intra-cranial hemorrhage in the 31st month after the operation. Therefore, the valve-related death rate was 4.3%, and the valve-related complication rate 8.6% on mid-term follow-up. 1, 3-, and 5-year valve- related event free rates were 90.8%, 79.5%, and 79.5%, respectively, while 1, follow-up. 1, 3-, and 5-year valve- related event free rates were 90.8%, 79.5%, and 79.5%, respectively, while 1, 3-, and 5-year survival rates were 100%, 88.8%, and 88.8%, respectively. CONCLUSION: The findings suggest that a complete removal of infected tissues is essential in the operative treatment of infectious endocarditis of the mitral valve. It is also suggested that when infected tissues are completely removed, neither type of material nor method of operation has a significant effect on the operation result. The postoperative results also suggest the need for a close follow-up observation of the patients suspected of having brain damage, which is caused by preoperative blood contamination or emboli from vegetation, for a possible cerebral vascular injury such as mycotic aneurysm.

BACKGROUND:
Acinetobacter baumannii infection is a significant health problem worldwide due to increased drug resistance. The limited antimicrobial alternatives for the treatment of severe infections by multidrug-resistant A. baumannii (MDRAB) make the search for other therapeutic options more urgent. Linalool, the major oil compound in Coriandrum sativum, was recently found to have high antibacterial activity against A. baumannii. The purpose of this study was to investigate the synergistic effect of linalool and colistin combinations against MDRAB and extensively drug-resistant A. baumannii (XDRAB).
METHODS:
A total of 51 strains of A. baumannii clinical isolates, consisting of 10 MDRAB and 41 XDRAB were tested. We determined the minimum inhibitory concentration (MIC) of linalool for the test strains using the broth microdilution method and searched for interactions using the time-kill assay.
RESULTS:
The time-kill assay showed that the linalool and colistin combination displayed a high rate of synergy (92.1%) (by synergy criteria 2), low rate of indifference (7.8%), and a high rate of bactericidal activity (74.5%) in the 51 clinical isolates of A. baumannii. The synergy rates for the linalool and colistin combination against MDRAB and XDRAB were 96% and 92.1%, respectively. No antagonism was observed for the linalool and colistin combination.
CONCLUSION
The combination of linalool and colistin showed a high synergy rate, which may be beneficial for controlling MDRAB infections. Therefore, this combination is a good candidate for in vivo studies to assess its efficacy in the treatment of MDRAB infections.

BACKGROUND AND OBJECTIVES: We compared the efficacy and safety of valsartan and rosuvastatin combination therapy with each treatment alone in hypercholesterolemic hypertensive patients. SUBJECTS AND METHODS: Patients who met inclusion criteria were randomized to receive 1 of the following 2-month drug regimens: valsartan 160 mg plus rosuvastatin 20 mg, valsartan 160 mg plus placebo, or rosuvastatin 20 mg plus placebo. The primary efficacy variables were change in sitting diastolic blood pressure (sitDBP) and sitting systolic blood pressure (sitSBP), and percentage change in low-density lipoprotein-cholesterol (LDL-C) in the combination, valsartan, and rosuvastatin groups. Adverse events (AEs) during the study were analyzed. RESULTS: A total of 354 patients were screened and 123 of them were finally randomized. Changes of sitDBP by least squares mean (LSM) were -11.1, -7.2, and -3.6 mm Hg, respectively, and was greater in the combination, as compared to both valsartan (p=0.02) and rosuvastatin (p<0.001). Changes of sitSBP by LSM were -13.2, -10.8, and -4.9 mm Hg, and was greater in the combination, as compared to rosuvastatin (p=0.006) and not valsartan (p=0.42). Percentage changes of LDL-C by LSM were -52, -4, and -47% in each group, and was greater in the combination, as compared to valsartan (p<0.001), similar to rosuvastatin (p=0.16). Most AEs were mild and resolved by the end of the study. CONCLUSION: Combination treatment with valsartan and rosuvastatin exhibited an additive blood pressure-lowering effect with acceptable tolerability, as compared to valsartan monotherapy. Its lipid lowering effect was similar to rosuvatatin monotherapy.
