PURPOSE: To evaluate the clinical characteristics of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures and assess the surgical outcomes of a novel, closed intramedullary nailing surgical approach designed to minimize fixation failure. MATERIALS AND METHODS: Between May 2013 and April 2017, 31 patients with intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures treated with closed intramedullary nailing or long proximal femoral nail antirotation (PFNA) were enrolled in this study. Preoperative data included age, sex, injury severity score, body mass index, location of shaft fracture, injury mechanism, accompanying traumatic injury, walking ability before injury, and surgical timing. Perioperative outcomes, including follow-up period, types of intramedullary nails, number of blocking screws used, operation time, and blood loss were assessed. Radiologic outcomes, including union rate, time from surgery to union, and femoral shortening, and clinical outcomes, including hip flexion, walking ability, and Harris hip score were also evaluated. RESULTS: A total of 29 unions (93.5%) were achieved. The time to union was 16.8 months (range, 11–25 months) for hip fractures (15.7 weeks for intertrochanteric fractures and 21.7 weeks for subtrochanteric fractures) and 22.8 months for femoral shaft fractures. There were no significant differences in surgical outcomes between the two groups except for type of intramedullary nail. CONCLUSION: Closed intramedullary nailing in the treatment of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures may be a good surgical option. However, fixation of femoral shaft fractures might not be sufficient depending on the implant design.

Serum lactate dehydrogenase isoenzyme are separated 5 fractions (LD1-LD5) in normal serum by agarose electrophoresis. An unusual band on the cathodic side of LD5 isoenzyme has been found on lactate dehydrogenase electrophoresis is of serum, called LD6, and the presence of which signifies a poor prognosis for the patients of myocardial infarction. In recent, we have experienced LD6 in two patients with myocardial infarction. Cardiac arrest was noted within 24 hours after exhibition of LD6 extra band and they did not recover from their illness.

Malignant pleural effusion in breast cancer has been associated with poor prognosis. The response rate of local treatment has been very low and in some case, complications have resulted in death. We investigated the efficacy and safety of paclitaxel, as an intrapleural chemotherapeutic agent. From January 2006 to December 2009, ten breast cancer patients who had developed malignant pleural effusion were infused with intrapleural paclitaxel through a chest tube, which was clamped for 48 hours. The chest tube was maintained until drainage was reduced to less than 50-100 mL/day. The average time spent with a chest tube attached following intrapleural chemotherapy was 9.3 days. During the follow-up period, six patients had no recurrent pleural effusion and two received a second round of intrapleural chemotherapy following which no further pleural effusion recurred. There were no severe side effects except for mild toxicity. It is suggested that intrapleural paclitaxel chemotherapy may be superior to conventional local treatment and may represent an effective treatment modality with low toxicity.

PURPOSE: Conventional total gastrectomy with Roux-en-Y esophagojejunostomy has certain limitations such as insufficient food reservoir and malabsorption of nutrients. Therefore, we performed reconstruction of the jejunal pouch interposition (JPI) after near-total gastrectomy preserving the lower esophageal sphincter (LES). We compared the technical feasibility, safety, and surgical outcome of this operation with conventional total gastrectomy accompanying with Roux-en-Y esophagojejunostomy. METHODS: From April 2003 to October 2005, 15 LES-preserving, near-total gastrectomies with JPI (LES-JPI group) were performed. The clinical features and surgical outcomes were retrospectively compared with 17 cases of conventional R-Y esophagojejunostomy. Statistical analysis was performed using Fisher's exact test for categorical data and an unpaired t-test for continuous data. RESULTS: Clinicopathological features of the LES-JPI and R-Y groups did not show differences excepting patient age (50.8+/-5.8 years vs. 62.8+/-12.4, respectively; P=0.002) and the depth of tumor invasion (T1-T2; 11~4 vs. 5~12; P=0.032). The operative outcomes for the two groups significantly differed in terms of operation time (676 vs. 484 min; P=0.008) and blood loss (424 vs. 336 ml; P=0.006). Postoperative gastrofiberscopic examination of all LES-JPI patients showed no esophageal reflux or strictures and intact LES. In addition, the LES-JPI group did not experience swallowing difficulty or stricture. CONCLUSION: LES-preserving total gastrectomy with JPI is a feasible and safe procedure for patients with upper gastric cancer.

PURPOSE: The genetic polymorphism and intracellular activity of methylenetetrahydrofolate reductase (MTHFR) and thymidylate synthase (TS) is clinically associated with carcinogenesis and biological therapeutic effect in gastrointestinal malignancies. We aimed to elucidate the susceptibility of gastric cancer according to MTHFR and TS gene polymorphism. METHODS: This study was designed as a hospital-based case-control study in a single institute. The gastric cancer group (n=300) for the study was diagnosed at first time as tubular adenocarcinoma, and the control group (n=100) was diagnosed as no malignancy in the endoscopic biopsy. The genetic polymorphism of TS and MTHFR were confirmed by PCR. RESULTS: The MTHFR mutant type had a more than 2-fold increased risk of developing gastric cancer (RR: 2.341). But, only heterozygote type (677CT) revealed significantly higher susceptibility compared to wild type (RR: 2.581). In TS gene genotype, the mutant genotype rate (2R/3R and 3R/3R) was significantly higher in gastric cancer group compared to control group (P=0.008), and the mutant type had a more than 3-fold increased risk of developing gastric cancer (RR: 3.222). In combined MTHFR and TS, 677CT+2R/3R and 677CT+3R/3R there was more than a 3-fold increased risk rate of developing gastric cancer compared with other combinations (RR, 3.474 in 677CT with 2R/3R; RR, 3.895 in 677CT with 3R/3R). CONCLUSION: This study shows a significant association between the MTHFR and TS polymorphisms and susceptibility to gastric cancer, providing a genetic basis. The polymorphisms study of two genes could be applied as susceptibility markers, clinically, for gastric cancer.

Supraaortic stenosis is a localized or diffuse congenital narrowing of the ascending aorta at the levels of superior margin of the sinus of Valsalva, just above coronary arteries. Hemodynamically, it is a usually manifestated as aortic stenosis especially when it combined with subaortic membrane. And there is no case report of supraaortic stenosis combined with subaortic membrane which has aortic valvular reurgitation due to secondary change of dilated sinus of Valsalva by supraaortic ridge. We have experienced a case of aortic regurgitation associated with supraaortic ridge combined with subvalvular aortic membrane.

PURPOSE: For most surgeons, colon interposition after gastrectomy remains an infrequently performed procedure because of its complexity. The aim of this study was to assess its technical feasibility and safety as a post-gastrectomy reconstruction method by reviewing our experience with colon interposition. MATERIALS AND METHODS: From March 2001 to February 2002, 30 colon interpositions after- gastrectomy were done with using the ileo-ascending or transverse colon. We analyzed the clinicopathologic features and the surgical outcomes. RESULTS: There were 16 males and 14 females in this study with a mean age of 67.5 years (range: 31 to 76 years). Twenty-five ascending colons and 5 transverse colons were used for the interposition, respectively. The mean operation time was 373 minutes (range: 204 to 600 minutes). There were 9 operative morbidities (30%) and 1 operative mortality. The restoration of bowel motility was noted at 3.8 postoperative days; a soft diet was started at 4.9 postoperative days and the duration of the hospital stay was 18.2 days. The percentage of weight loss in the patients with total, proximal and distal gastrectomy was 16.3%, 14.0% and 8.8%, respectively, at 6 months, and thereafter the weight loss gradually recovered as 8.1%, 7.5% and 5.6%, respectively, at 5 years postoperatively. Gastric stasis was the one of the most meaningful long-term complications, and especially in the patients who underwent distal gastrectomy with colon interposition. CONCLUSION: Colon interposition after gastrectomy was a very complex procedure with a long operating time and many anastomosis sites. The postoperative outcomes failed to achieve satisfactory weight gain and the patients displayed postprandial symptoms. This suggested that this procedure was not an appropriate procedure for conventional reconstruction after gastrectomy.

Excessive calcium is thought to be a critical step in various neurodegenerative processes including ischemia. Calbindin D28k (CB), calretinin (CR), and parvalbumin (PV), members of the EF-hand calcium-binding protein family, are thought to play a neuroprotective role in various pathologic conditions by serving as a buffer against excessive calcium. The expression of CB, PV and CR in the ischemic rat retina induced by increasing intraocular pressure was investigated at the transcript and protein levels, by means of the quantitative real-time reverse transcription-polymerase chain reaction, western blot and immunohistochemistry. The transcript and protein levels of CB, which is strongly expressed in the horizontal cells in both normal and affected retinas, were not changed significantly and the number of CB-expressing horizontal cells remained unchanged throughout the experimental period 8 weeks after ischemia/reperfusion injury. At both the transcript and protein levels, however, CR, which is strongly expressed in several types of amacrine, ganglion, and displaced amacrine cells in both normal and affected retinas, was decreased. CR-expressing ganglion cell number was particularly decreased in ischemic retinas. Similar to the CR, PV transcript and protein levels, and PV-expressing AII amacrine cell number were decreased. Interestingly, in ischemic retinas PV was transiently expressed in putative cone bipolar cell types possibly those that connect with AII amacrine cells via gap junctions. These results suggest that these three calcium binding proteins may play different neuroprotective roles in ischemic insult by their ability to buffer calcium in the rat retina.
