We experienced one case of an unusual acute osteomyelitis of orbital margin, of which frontal, zygomatic and maxillary bone was involved in 10-month old infant. His clinical symptomes were similar to the acute osteomyelitis of superior maxilla but the primary site seemed to be in the frontal bone by history. We treated him with massive antibiotics and surgery (anterior approach). The causative organism was staphylococcus sureus, being very sensitive to penicillin. Also we reviewed the literatures of the orbital osteomyelitis comparing with thia case.

Aniridia is a congenital lack of iris and rudimentary iris tissue, almost always bilateral, occuring as a dominant characteristic by an autosomal gene with high penetrance and variable expression. The syndrome of congenital aniridia may be composed of four phenotypes. The authors have experienced one an iridic family: mother, one daughter and four sons. The most family members have ectopia lentis. cataract. corneal pannus and glaucoma as well as aniridia, so they were expected the first phenotype of aniridia due to a failure in development of retinal ectoderm. Two sons of them were operated in Chungnam National University Hospital for control of glaucoma and visual impairment due to cataractous ectopic lens. In one case the intraocular pressure was not controlled after trabeculectomy and in another case lens extraction resulted in visual improvement. The review was made of relating literatures for the case of aniridia family, breifly.

PURPOSE: N-13 ammonia uptake and retention in the myocardium is related to perfusion and metabolism. There are several potential advantages of N-13 ammonia positron emission tomography (PET) to detect myocardial ischemia, such as higher spatial resolution, greater counting efficiencies, and robust attenuation correction. But there are few reports comparing Tc-99m myocardial perfusion single photon emission tomography (MPS) and N-13 ammonia PET. We thus compared adenosine stress N-13 ammonia PET/CT and Tc-99m sestamibi MPS in patients with suspected coronary artery stenosis. MATERIALS AND METHODS: Seventeen patients (male 13 : 63+/-11 years old) underwent adenosine stress N-13 ammonia PET/CT (Discovery ST, GE), Tc-99m sestamibi MPS (dual head gamma camera, Hawkeye, GE) and coronary angiography within 1 week. N-13 ammonia PET/CT and Tc-99m sestamibi MPS images were assessed with a 20-segment model by visual interpretation and quantitative analysis using automatic quantitative software (Myovation, GE). RESULTS: Both sensitivities and specificities of detecting an individual coronary artery stenosis were higher for N-13 ammonia PET/CT than Tc-99m sestamibi MPS (PET/CT: 91%/ 89% vs MPS: 65%/ 82%). N-13 ammonia PET/CT showed reversibility in 52% of segments that were considered non-reversibile by Tc-99m sestamibi MPS. In the 110 myocardial segments supplied by the stenotic coronary artery, N-13 ammonia PET/CT showed higher count densities than Tc-99m MPS on rest study (p<0.01), and the difference of count density between the stress and the rest studies was also larger on N-13 ammonia PET/CT. CONCLUSION: Adenosine stress N-13 ammonia PET/CT had higher diagnostic sensitivity and specificity, more reversibility of perfusion defects and greater stress/rest uptake differences than Tc-99m sestamibi MPS. Accordingly, N-13 ammonia PET/CT might offer better assessment of myocardial ischemia and viability.

Gastrointestinal fistula is a disease of varying etiologies. It may occur spontaneously or as a result of an iatrogenic cause. Spontaneous fistula occurs as a result of an inflammatory process, malignancy or radiotherapy. The majority of fistula are caused by iatrogenic causes, most frequently as a complication of surgical intervention. Treatment of gastrointestinal fistulae usually consists of surgery and conservative management such as nutritional support and control of inflammation. Recently, it has been reported that gastrointestinal fistulae can be treated endoscopically using tissue adhesive agents such as Histoacryl and fibrin glue. We report two cases of gastrointestinal fistulae that were successfully treated by endoscopic local injection therapy with a review of literature.

BACKGROUND/AIMS: Various magnifying endoscopic classifications have been introduced in esophageal and gastric lesions. However, studies on an agreement between observers according to the form classification of magnifiying endoscopic findings have not been performed yet. The aim of this study was to determine the interobserver agreement for magnifying endoscopic classifications. METHODS: The patients were divided into 3 groups. The first group of patients had post-EMR ulcer scar (50 cases), the second group, elevated gastric lesion (38 cases), and the third group, gastritis (43 cases). Two mucosal patterns were used in the post-EMR ulcer scar group, 6 mucosal patterns in the elevated gastric lesion group, and 3 patterns of the collecting venule in the gastritis group. Three experienced observers (A, B, C) blinded to the patients' data participated in this study. The agreement between observers was evaluated by calculated kappa. The kappa value of 0.75 or greater was rated excellent, 0.4~0.74, fair to good, and 0.4 or less, poor. RESULTS: Regarding 2 mucosal pattern in post-EMR ulcer scar, agreements between A and B, A and C, and B and C were 0.896, 0.793, and 0.901, respectively (p<0.01). Regarding 6 mucosal patterns in elevated gastric lesion, agreements between A and B, A and C, and B and C were 0.607, 0.458, and 0.557, respectively (p<0.01). Regarding 3 collecting venule pattern in gastritis, agreements between A and B, A and C, and B and C were 0.822, 0.823, and 0.751, respectively (p<0.01). CONCLUSIONS: Interobserver agreement is good to excellent in mucosal pattern and collecting venule by magnifying endoscopy. However magnifying endoscopic classification needs to be refinded in order to improve an agreement between observers.

BACKGROUND/AIMS: The relationship between the symptoms and severity of GERD may be difficult to prove. The intensity and frequency of reflux induced symptoms are poor predictors of the presence or severity of an endoscopic mucosal break. The aim of this study was to determine which factors can be predicted by the presence of GERD symptoms among esophageal sensitivity to acid, abnormal acid reflux, and severity of esophagitis in pateints with reflux esophagitis. METHODS: Fourty-four patients who were diagnosed with reflux esophagitis by an endoscopy at a tertiary medical facility, were given a validated questionnaire, and underwent an acid perfusion test, 24 hr ambulatory esophageal pH monitoring, and esophageal manometry. These patients were divided into a symptomatic group and asymptomatic group according to the questionaire. Comparisons between the two groups for each factor were analyzed by Chi-square. RESULT: Of 44 patients, 26 had symptoms and 18 did not. The positive and equivocal rates of the acid perfusion test were not different between the symptomatic and asymptomatic groups (47% vs. 39%). The abnormal reflux rate (DeMeester score > 14.72) from pH monitoring was significantly higher in the symptomatic group than in the asymptomatic group (65% vs. 28%, p < 0.05). The severity of esophagitis, presence of a hiatal hernia, and abnormal esophageal manometric findings were not different between the two groups. CONCLUSION: It would be impossible to predict esophageal sensitivity to acid, severity of the esophagitis grade, and the presence of hiatal hernia with GERD symptoms, but it could be possible to predict abnormal gastroesophageal reflux.

BACKGROUND/AIMS: Capsule endoscopy is an effective diagnostic tool for detecting small bowel disease. However, the method of bowel preparation for capsule endoscopy has not been standardized. The aim of this study was to evaluate the efficacy of oral sodium phosphate as a preparation for capsule endoscopy. METHODS: A total of 129 cases who underwent capsule endoscopy from Mar. 2003 to Sep. 2004 were analyzed retrospectively. Eighty- eight cases were prepared with sennosides (Alaxyl(R)) and 41 cases were prepared with sodium phosphate. The intestinal mucosa was defined as being unclean if the intestinal content, food materials, and bubbles covered more than 25% of the mucosal surface. Using a stopwatch, the exact time of the unclean image was recorded. The percentage of the unclean image for the small intestinal transit time (SITT) was calculated as an objective score. Small bowel cleansing was considered 'adequate' if the objective score was <10% and 'inadequate' if the objective score was 10% or greater. RESULTS: 35 cases (40%) showed an adequate image in the sennosides and simethicone group and 26 cases (63%) showed an adequate image in the sodium phosphate and simethicone group. The adequacy rate was significantly higher in the sodium phosphate group than in the sennosides group (p<0.05). CONCLUSIONS: Capsule endoscopy prepared by sodium phosphate and simethicone produced a better visual image than sennosides and simethicone.

BACKGROUND/AIMS: The discrepancy of the histopathological diagnosis between endoscopic forcep biopsy, surgery and endoscopic mucosal resection (EMR), has been reported on in a previous study. We compared the results of endoscopic forcep biopsy and the histopathologic diagnosis after performing endoscopic submucosal dissection (ESD). METHODS: We retrospectively reviewed 434 lesions for which we were able to compare the post-ESD histopathologic results with the endoscopic biopsy. RESULTS: 1) Of the 14 lesions that showed chronic gastritis or atypia by endoscopic biopsy, 9 were diagnosed with carcinoma in situ or adenocarcinoma after ESD. 2) fifty one of 141 lesions that showed low grade dysplasia on the endoscopic biopsy were diagnosed with carcinoma in situ or adenocarcinoma after ESD. 3) Of the 60 lesions that showed high grade dysplasia on the endoscopic biopsy, 46 were diagnosis with carcinoma in situ or adenocarcinoma after ESD. CONCLUSIONS: The discrepancy of the histopathological diagnosis was found between ESD and forcep biopsy. In light of these results, if a lesion that is suspected to be EGC, although it is not diagnosed by endoscopic biopsy, then it should be confirmed by ESD.

BACKGROUND/AIMS: We investigated the clinical significance of the criteria of the absolute and relative depth of invasion for submucosal invasive colorectal carcinomas. METHODS: We analyzed retrospectively the clinicopathological features of 29 submucosal invasive colorectal cancers. The relative depth of submucosal invasion was evaluated by a relative (sm1, 2, 3) classification and the absolute depth of submucosal invasion was measured in micrometers from the lower border of the muscularis mucosa to the deepest cancer gland. RESULTS: All sm1 cancers showed a submucosal layer invasion of less than 1,000micronm; invasion was seen between 500micronm and 1,000micronm. The rate of lymphovascular invasion was higher for sm1c, sm2 and sm3 than for sm1a and sm1b, and the rate of invasion was higher for a level of 500micronm or more than for a level of 500micronm or less for the depth of submucosal invasion. One of sixteen patients that underwent surgery showed lymph node involvement. For this patient, the relative depth of invasion was sm1c and the absolute depth was 900micronm. CONCLUSIONS: Endoscopically treated submucosal colorectal cancer needs to be evaluated by the absolute depth in addition to the relative depth. It seems that a submucosal invasive cancer less than 500micronm in submucosal depth probably can be treated by endoscopic resection.
