Background: Impaired diastolic heart function has been observed in persons with non-alcoholic fatty liver disease (NAFLD) and/or with type 2 diabetes mellitus (T2DM). However, it is unclear whether NAFLD fibrotic progression, i.e., non-alcoholic steatohepatitis, poses an independent risk for diastolic dysfunction in T2DM. We investigated the association between liver fibrosis and left ventricular (LV) diastolic dysfunction in T2DM. Methods: We analyzed 606 patients with T2DM, aged ≥50 years, who had undergone liver ultrasonography and pulsed-wave Doppler echocardiography. Insulin sensitivity was measured by short insulin tolerance test. Presence of NAFLD and/or advanced liver fibrosis was determined by abdominal ultrasonography and NAFLD fibrosis score (NFS). LV diastolic dysfunction was defined according to transmitral peak early to late ventricular filling (E/A) ratio and deceleration time, using echocardiography. Results: LV diastolic dysfunction was significantly more prevalent in the NAFLD versus non-NAFLD group (59.7% vs. 49.0%, P=0.011). When NAFLD was stratified by NFS, subjects with advanced liver fibrosis exhibited a higher prevalence of diastolic dysfunction (49.0%, 50.7%, 61.8%; none, simple steatosis, advanced fibrosis, respectively; P for trend=0.003). In multivariable logistic regression, liver fibrosis was independently associated with diastolic dysfunction (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.07 to 2.34; P=0.022) after adjusting for insulin resistance and cardiometabolic risk factors. This association remained significant in patients without insulin resistance (OR, 4.32; 95% CI, 1.73 to 11.51; P=0.002). Conclusions Liver fibrosis was associated with LV diastolic dysfunction in patients with T2DM and may be an independent risk factor for diastolic dysfunction, especially in patients without systemic insulin resistance.

PURPOSE: Medial capsulorrhaphy is additional hallux reduction method following various hallux reduction procedures and we are going to report author's opinion about several methods of medial capsulorrhaphy. MATERIALS AND METHODS: We performed three kinds of medial capsulotomy and imbricatory capsulorrhaphy in hallux valgus surgery. Through 8 cadavar study, we compared the easiness of sesamoid reduction and hallux valgus angle reduction. Also, we measured thickness of capsule in various portions. RESULTS: Longitudinal capsule incision and imbrication was useful in sesamoid reduction and vertical procedures was useful in hallux valgus angle reduction. The capsule thickness was measured thickest in dorsal and distal portioin. CONCLUSION: The methods of medial capsulorrhaphy should be planned preoperatively considering individual hallux deformities. These selected medial capsulorrhaphy can help the reduction of hallux valgus deformity correction and its maintenance

A 39 years old woman was admitted to the hospital because of recurrent hemoptysis. On a bronchoscopic inspection, nodular shaped mass-like lesions were found on the orifice of right middle and lower lobar bronchus and a biopsy was performed. This was immediately followed by massive bleeding into the airways. The bleeding could not be controlled by nonsurgical treatment. Immediately she underwent a right middle and lower bilobectomy in order to control of bleeding. Biopsy revealed the bleeding to have been caused by a biopsy injury of an abnormal artery that had run superficially in the bronchial mucosa.

Gastric adenoma (dysplasia) is a precancerous lesion. Therefore, managements of gastric adenomas are important for preventing the development of gastric cancers and for detecting gastric cancers at earlier stages. The Vienna classification divides gastric adenomas into two categories: high-grade dysplasia and low-grade dysplasia. Generally, endoscopic resection is performed for adenoma with high-grade dysplasia due to the coexistence of carcinoma and the potential of progression to carcinomas. However, the treatments of adenoma with low-grade dysplasia remain controversial. Currently two treatment strategies for the low-grade type have been suggested; First is the ‘wait and see’ strategy; Second is endoscopic treatment (e.g., endoscopic mucosal resection, endoscopic submucosal dissection, or argon plasma coagulation). In this review, we discuss the current optimal strategies for endoscopic management of gastric adenoma.

Corneal neovascularization is a challenging problem in ophthalmologic practice. We evaluated the anti-angiogenic effect of recombinant tissue inhibitor of metalloproteinase type 2 (rTIMP-2) which is an endogenous inhibitor of matrix metalloproteinases. Sprague-Dawley rats of 6 weeks of age were used in this study. N-heptanol was applied to the eyes of the rats to induce chemical injury and eventual neovascularization. The rats were divided into 4 groups, 5 rats for each. We instilled only the phosphate buffered solution once a day for 10 days to the eyes of rats in the control group. Rats in group 1 received subconjunctival injection of 0.05 mgof rTIMP-2, those in group 2 received intraperitoneal injection of 0.05 mg of rTIMP-2, and those in group 3 received intraperitoneal injection of 0.1 mg of rTIMP-2 once a day for 10 days respectively. After 4 weeks, photographs of corneas were taken with a built-in camera of the slit lamp, and the eyes were enucleated. We made histologic specimens of the corneas and examined them with a light microscope. The severity of the neovascularization was quantified with angiogenesis scoring system. The group 1, 2 and 3 showed significant suppression of angiogenesis compared with the control respectively, but there was no statistically significant difference among their angiogenesis scores. Under the light microscope, the corneas of control group showed much more severe infiltration of inflammatory cells and higher density of new vessels compared with group 1, 2 and 3. We hypothesize that TIMP-2 suppressed the angiogenesis in chemical injury of cornea and TIMP-2 might benefit those patients with corneal neo-vascularization, although careful further studies are required in humans.

Thirty nine strains and 109 strains of Shigella sonnei were isolated from the outbreaks of Youngchun and Kyungju, respectively, while 15 strains were isolated from sporadic cases of eight regions in Kyungbuk province from September to November in 1998. We investigated the relationship among the S. sonnei strains by using biochemical characteristics, biotyping, antibiotic resistance pattern, and plasmid profile. Among the isolates, seven strains of S. sonnei isolated in Youngchun showed gelatin hydrolyase positive but the others showed gelatin hydrolyase negative. One hundred and fifty two strains were a type, while eleven among thirty nine strains isolated in Youngchun were g type. Antibiotics resistance patterns of S. sonnei strains isolated in Youngchun and Kyungju were significantly different. Thirty nine strains of S. sonnei isolated in Youngchun were resistant to SM, TE, and TMP/SMX, while eighty six of S. sonnei among one hundred and nine strains isolated in Kyungju were resistant to AM, CB, K, SM, TE, and TMP/SMX. Antibiotics resistance patterns of residual twenty three isolates were similar to those of eighty six strains. The Plasmid profiles of strains of S. sonnei isolated from the Kyungju were different from those of S. sonnei strains isolated in Youngchun. The Plasmid profiles of S. sonnei strains isolated from Youngchun were identical to those of a S. sonnei strains randomly selected from the outbreak in Daegu in 1998. The Plasmid profiles of S. sonnei strains isolated from Kyungju were identical to those of two strains of S. sonnei randomly selected from the outbreaks of Kanglung and Wonju in 1998. From the above results, it is considered that the strains of S. sonnei isolated from Kyungju and Youngchun region are not identical clone.

Accurate diagnosis of Helicobacter pylori (H. pylori) infection is mandatory for the effective management of many gastroduodenal diseases. Currently, various diagnostic methods are available for detecting these infections, and the choice of method should take into account the clinical condition, accessibility, advantage, disadvantage, as well as cost-effectiveness. The diagnostic methods are divided into invasive (endoscopic-based) and non-invasive methods. Non-invasive methods included urea breath test, stool antigen test, serology, and molecular methods. Invasive methods included endoscopic imaging, rapid urease test, histology, culture, and molecular methods. In this article, we provide a review of the currently available options and recent advances of various diagnostic methods.
