The main goals of surgical teatment of thoracolumbar vertebral fractures are to achieve reduction, stability and early, painless mobilization. A further aim is to avoid late malposition and to preserve mobility and lordosis. The main disadvantage of Harrington instrumentation and similar methods are that this device fixate five to seven vertebrae. The Cotrel-Dubousset(C-D) instrumentation provides a stable construct for fixation of spine fracture. The advantages of C-D pedicle screw for thoracolumbar spinal fractures are that compression or distraction force can be applied in the same rod and used to achieve anatomical reduction of spinal fractures and rigid fixation can be obtained with short instrumentation. The C-D instumentation was done for 15 unstable thoracolumbar spinal fractures at Seoul Red Cross Hospital from January, 1988 to January, 1990. The results were as follows. 1. The most common cause of the spine fracture was fall down, and majority are within 20-40 old age. 2. The most common involved site was T12 and Ll vertebrae (66.7%). 3. The most common type of injury was burst fracture by according to Denis classification(60%). 4. The complication was developed mostly in neurological deficient patient. 5. The advantage of the C-D instrumentation: (1) rigid and short osteosynthesis of spine fracture, (2) compression or distraction force can be applied in the same rod, (3) early mobilization with a brace is possible. 6. The rigid fixation can be obtained.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is a relatively rare disease, characterized by the occurrence of multiple endocrine tumors in the parathyroid and pituitary glands as well as the pancreas. Here, we report a case of MEN1 with neuroendocrine tumors (NETs) in the stomach, duodenum, and pancreas. A 53-year-old man visited our hospital to manage gastric NET. Five years prior to his visit, he had undergone surgery for incidental meningioma. His brother had pancreatic nodules and a history of surgery for adrenal adenoma. His brother's daughter also had pancreatic nodules, but had not undergone surgery. The lesion was treated by endoscopic submucosal dissection and diagnosed as a grade 1 NET. Another small NET was detected in the second duodenal portion, resected by endoscopic submucosal dissection, which was also diagnosed as a grade 1 NET. During evaluation, three nodules were detected in the pancreas, and no evidence of pituitary, parathyroid tumors, or metastasis was observed. After surgery, the pancreatic lesions were diagnosed as NETs, with the same immunohistochemical patterns as those of the stomach and duodenum. Genetic testing was performed, and a heterozygous mutation was detected in the MEN1 gene, which is located on 11q13.

Secondary involvement of the gallbladder by systemic lymphoma is exceedingly rare and relapsed diffuse large B cell lymphoma of the gallbladder has not been reported. A 78-year-old man was admitted to the hospital due to epigastric pain and jaundice. His past medical history was remarkable for diagnosis with diffuse large B-cell lymphoma of the ileum 5 years ago. He underwent right hemicolectomy and three cycles of adjuvant chemotherapy and had complete remission. Abdominal computed tomography showed choledocholithiasis and focal thickening at fundus of the gallbladder. The patient underwent open cholecystectomy. Pathologic examination revealed diffuse large B-cell lymphoma. We report a case of solitary, relapsed diffuse large B-cell lymphoma of the gallbladder with literature review.

Concurrence of primary gastric adenocarcinoma and lymphoma have been described very rarely in the literature; its incidence is estimated at 0.08%. To our knowledge, there are no reports about a collision tumor comprising early gastric cancer and diffuse large B-cell lymphoma from the same lesion. The term "collision tumor" refers to the coexistence of two or more histologically distinct tumors within the same mass with no histologic admixture. A 76-year-old man complained of a 5-month-history of dyspepsia, and underwent esophagogastroduodenoscopy. Endoscopic findings showed a nodular, round, flat mass lesion in the upper body, therefore we performed endoscopic submucosal dissection (ESD). Pathologic findings revealed a well-differentiated adenocarcinoma accompanied by diffuse large B-cell lymphoma without evidence of Helicobacter pylori infection. Conventional CT and PET-CT scans revealed metastatic lymph nodes in the parotid gland, submandibular gland, maxillary gland and the inguinal regions. The pathogenesis of a collision tumor comprising two different cancers is not well understood. In addition, there are no established treatment guidelines in this series. In the current case, the patient underwent ESD for the removal of adenocarcinoma concomitantly with chemotherapy for the management of metastatic lymphoma.

This study describes the first record of Globocephalus samoensis (Nematoda: Ancylostomatidae) recovered in wild boars from southwestern regions of Korea. Gastrointestinal tracts of 111 Korean wild boars (Sus scrofa coreanus) hunted from mountains in Suncheon-si, Gwangyang-si, and Boseong-gun between 2009 and 2012 were examined for their visceral helminths. G. samoensis, as identified by morphological characteristics of the head and tail, were recovered from the small intestine of 51 (45.9%) wild boars. Worms were found from 7 of 28 wild boars (25.0%) from Suncheon-si, 40 of 79 (50.6%) from Gwangyang-si, and all 4 (100%) from Boseong-gun. The length of adult females was 7.2+/-0.5 mm, and the thickest part of the body measured the average 0.47+/-0.03 mm, while those of males were 6.52+/-0.19 and 0.37+/-0.02 mm, respectively. The buccal cavity was equipped with a pair of large and bicuspid subventral lancets near the base of the capsule. The average length of spicules of males was 0.45+/-0.02 mm. By the present study, G. samoensis is recorded for the first time in southwestern regions of Korea. Additionally, morphological characteristics and identification keys provided in the present study will be helpful in the faunistic and taxonomic studies for strongylid nematodes in both domestic and wild pigs. The infection of G. samoensis apparently did not elicit pathologic lesions, as revealed by macroscopic observation during the autopsy of all wild boars in this study.

PURPOSE: To evaluate the efficacy and safety of nitofurazone-coated urinary catheter in inhibitory activity of catheter associated urinary tract infection (CAUTI). METHODS: From March to September 2001, 177 patients in five university hospitals who were expected to use urinary catheters and be satisfied with the inclusion, exclusion criteria were analyzed. Through urine culture, we compared the incidence rate and onset of CAUTI after catheterization of standard silicone urinary catheters (control group) and nitofurazone-coated catheters (experimental group). CAUTI was defined as over 103 CFU/mL of bacteria in urine culture. The catheter surface was examined by scanning electron microscopy (SEM) to analyze the bacteial biofilms. RESULTS: The incidence rate of CAUTI was lower in experimental group than in control group but there was no statistical significancy. However, in the patients who had indwelling urinary catheters for 5~7 days, the incidence rate of CAUTI was significantly low in experimental group. Depending on catheter insertion period, the incidence onset of CAUTI was analyzed. It was found that the longer the insertion period was, the lower the incidence rate of CAUTI in experimental group was than in control group, but there was no statistical significancy. In the patients who had indwelling urinary catheters for 5~7 days, the incidence rate of CAUTI was significantly low in experimental group. According to the result of this study, patient who was older and had longer insertion- period, had higher incidence rate of CAUTI. SEM showed the formation of bacterial biofilm in silicone catheters throughout the 5~7 days, but deterioration of the bacterial biofilm was visible on the surface of nitofurazone-coated catheters. There was no side-effect in any groups. CONCLUSION: This study suggests that nitofurazone-coated catheters can be useful for inhibition of urinary tract infection, with systemic and local safety, in patients who have indwelling urinary catheter more than 5 days and old-age paitents.

The nose is a complex three-dimensional structure and represents a major aesthetic focus of the face. As a gold standard for nasal soft tissue reconstruction, the ‘forehead flap’ provides reconstructive surgeons a robust pedicle and large amount of tissue to reconstruct almost any defect. However, during this process, some hair can be unintentionally introduced to the nose. Accordingly, laser hair removal is sometimes needed, but blood circulation and flap survival should be carefully monitored.Despite careful evaluation, a third-degree burn occurred in our patient that required eight weeks to heal. Here, we report on a burn resulting from epilation conducted 2 weeks after forehead flap for nasal reconstruction.

PURPOSE: N-acetylcysteine (NAC) is a potent antioxidant, and a free radical scavenger. We investigated the possible effects of NAC after ischemia/reperfusion (I/R) of rat bladder. MATERIALS AND METHODS: I/R injury was induced by abdominal aorta clamping and ischemia for 60minutes, followed by 120minutes reperfusion. Twenty rats were divided into four groups: sham operation + saline group (S+S), sham operation + NAC group (S+NAC), I/R + saline group (I/R+S), I/R + NAC group (I/R+NAC). Blood levels of reactive oxygen species (ROS) were determined using the free oxygen radical tests (FORT). Superoxide generation was measured based on lucigenin-enhanced chemiluminescence. The level of malondialdehyde (MDA) was analyzed in order to measure lipid peroxidation. RESULTS: In I/R+S group, the isometric contractile responses to carbachol were significant lower than other groups and were reversed by the pretreatment with NAC. The level of FORT and MDA showed a marked increase in I/R+S group compared with S+S group. NADPH-stimulated superoxide production was also significantly increased. I/R+NAC decreased these parameters compared with I/R+S group. CONCLUSION: Our results suggest that treatment with NAC reversed the low contractile responses of rat bladder and prevented oxidative stress following I/R.
