Crohn's disease is a chronic, nonspecific inflammatory process which most commonly involves the terminal ileum, but which can affect any region of the gastrointestinal tract from the mouth to the anus. When Crohn's disease does involve the upper gastrointestinal tract, there is nearly always concomitant disease in the small bowel or colon. However isolated gastric Crohn's disease is a rare entity, and gastroduodenal involvement in Crohn's disease has been considered unusual, having an incidence of 1.5 to 7.0%. Gastric Crohn's disease usually localizes to antrum of the stomach and or the pyloroduodenal junction. No single feature is pathognomonic of Crohn' disease, and the diagnosis is based on supportive clinical, radiographic, endoscopic, and pathologic findings. Crohn's disease is invariably a diagnosis of exclusion, so infectious, neoplastic, ischemic, infiltrative, and other inflammatory processes must be ruled out. Usually a patient with isolated Crohn's disease of the stomach will have the clinical symptoms of nausea, vomiting, and epigastric pain, and there will be radiographic evidence of a small contracted stomach (or occasionally, a huge dilated stomach). The treatment of stomach Crohn's disease is palliative and symptomatic. In this paper, we describe a patient with Crohn's disease who had diffuse involvement of the entire stomach without any evidence of involvement elsewhere in the gastrointestinal tract.

The purpose of this study was to evaluate the bone age and hand anomaly in Down syndrome patients. We reviewed radiographs in 52 children and youths with Down syndrome, aged from 2 to 23 years. The characteristic findings of hand anomaly were observed in the middle phalanx of the fifth finger, with the following incidence; brachymesophalangia (44%), clinodactyly (48%), and dysmesophalangia (15%). Pseudoepiphysis (21%) was found typically at the distal end of the first metacarpal bone and proximal end of the second metacarpal bone. Up to 8.5 years of age, bone maturation was retarded and thereafter bone age accelarated in advance of chronologic age. These findings may provide valuable information relative to the diagnosis and treatment of hand anomaly in Down syndrome.

PURPOSE: To assess the accuracy of magnetic resonance(MR) arthrography in the diagnosis of anterior labral tear of the shoulder. MATERIALS AND METHODS: Between Semptember 1996 and February 2000, MR arthrography of the shoulder was performed in 281 patients with a history of shoulder pain or instability. Among this total, only 157 shoulders in 154 patients who underwent arthroscopy or open surgery 0 to 230 (average, 20.9) days after MR arthrography were included in this study; the subjects comprised of 150 males and 4 females with an average age of 23.3 years. MR arthrographs of these 154 patients were analyzed for the presence of anterior labral tears, and the findings were correlated with the arthroscopic and surgical findings. Anterior labral tear was classified as A to D according to its location, as determined by arthroscopy and surgery. (A=4 to 6 o 'clock direction, anteroinferior; B=2 to 4 o 'clock direction, central; C=12 to 2 o 'clock direction, anterosuperior; D= SLAP lesions). The retrospective analysis of MR arthrographs showing false-positive and negative findings was also undertaken. RESULTS: In the diagnosis of anterior labral tear, MR arthrography showed a sensitivity of 94%, a specificity of 90% and an accuracy of 91%. Anterior labral tears were confirmed by arthroscopy or surgery in 62 of the 157 shoulders (39%). Among 62 lesions, two (3%) were observed in area A, 32(52%) in area A+B, nine (15%) in area A+B+C, one(2%) in area A+B+D, 13(21%) in area A+B+C+D, two (3%) in area B+C, one(2%) in area B+D, and two(3%) in area C. Among ten false-positive cases, seven were focal lesions (two, three and two lesions in area A, B and C, respectively), and in the remaining three cases, located in area A+B, MR arthrography revealed thickening and deformation. All four false negatives were focal lesions (two in area A and two in area C). CONCLUSION: Other than in focal lesions, in which accuracy was relatively low, MR arthrography showed high sensitivity, specificity and accuracy in the diagnosis of anterior labral tear of the shoulder.

BACKGROUND: Esmolol is a short acting sympathetic beta receptor antagonist, and it was successfully applied to induced hypotension. Esmolol lowers blood pressure by decreasing cardiac output, and does not cause vasodilation. This property of esmolol may help to decrease bleeding during induced hypotension. In this study, we tried to elucidate the effect of esmolol on induced hypotension for total hip arthroplasty. METHOD: Twenty patients receiving total hip arthroplasty were randomly divided to two groups. Esmolol group (10 patients) received esmolol as a hypotensive agent, and sodium nitroprusside (SNP) group (10 patients) received SNP as a hypotensive agent. We measured arterial blood gas analysis, vital sign, amounts of bleeding, amounts of transfusion and administered fluid, and various laboratory findings. RESULTS: Induced hypotension was successfully performed in either esmolol and SNP group. Heart rate increased by SNP, and decreased by esmolol. There were no statistically significant differences between the two groups in amounts of bleeding, amounts of transfusion or administered fluid, and laboratory findings. Arterial oxygen tension was relatively constant in esmolol group, but decreased in SNP group. CONCLUSION: Esmolol can be used as a single hypotensive agent during induced hypotension without significant side effects during total hip arthroplasty.

Potentially, some donor site complications are associated with the harvesting of autogenous tricortical iliac bone grafts for anterior spinal fusion. The purpose of this study was to evaluate the reliability of the anterior iliac crest reconstruction after harvesting autogenous iliac grafts for anterior spinal fusion. We devided into two groups : the study group were the anterior iliac crest reconstruction in 57 patients with minimal twelve months follow up period, the control group were not the anterior iliac crest reconstruction in 21 patients who could not obtain the rib from retroperitoneal approach. The average follow up was obtained at 43.3 months(12 to 72 months) in study group, at 41.6 months(12 to 60 months) in control group. The study group had a tendency to improve the donor site pain after incorporation of the rib graft and the control group tend to remain the donor site pain till late especially in the thinner group and combined disease group. In residual deformity of the donor site, the study group was superior to the control group. Residual deformity of the study group was associated with the complications such as displacement and resorption of the grafts. Cosmetic residual deformity tends to be higher in the thinner group. Radiographically all rib gragts incorporated in situ in 51 patients despite of some cases of migration(Average 11 weeks and 4 days) and clinical results did not affect by biological behavior of rib grafts on the follow up radiogram. The authors attempted anterior iliac crest reconstruction using the implants (Mennen plate in 3 patients, threaded pin in 3 patients) after large harvesting of autogenous tricortical graft in 6 patients who could not obtain the rib from retroperitoneal approach or could not fit the rib too the defect. In those cases the results were satisfactory clinically. These results suggest anterior iliac crest reconstruction can minimize painful deformity after the harvesting of autogenous tricortical iliac grafts for anterior spinal fusion.

This study was conducted to evaluate the effect of PTSD on memory funtion and hippocampal volume, and to identify major variables correlated to hippocampal volume and memory function. Thirty four Vietnam veterans were collected for this study, among whom eighteen were PTSD patients and sixteen were combat control subjects. The author used Impact of Event Scale(IES), Combat Exposure Scale(CES), Hamilton Depression Rating Scale(HDRS) and Beck Depression Inventory(BDI). Korea Memory Assessment Scale(K-MAS) was assessed for memory function. Magnetic resonance imaging(MRI) was used to measure hippocampal volume. There were significant differences between PTSD and Non-PTSD veterans in IES, HDRS and BDI. Significant difference was found in verbal memory and total memory of K-MAS between PTSD and Non-PTSD veterans. There was significant difference in hippocampal volume between PTSD and Non-PTSD veterans. Short term memory, verbal memory and total memory were positively correlated to hippocampal volume. Hippocampal volume was negatively correlated to IES, HDRS, and BDI. These results suggest that PTSD severity be associated with hippocampal atrophy and memory dysfunction. Reduced or smaller hippocampal volume may be preexisting risk factor for stress exposure or the development of PTSD on combat exposure.

29 isoniazid (INH) resistant isolated strains and INH sensitive reference strain (H37Rv) of Mycobacterium tuberculosis were analysed by polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) and NciI restriction mapping for the detection of mutations in katG gene and inhA gene. The katG gene was divided into 3 parts (Akat, Bkat, Ckat; each part is about 800 bp) and amplified, inhA gene was amplified as a whole. Each of the amplified 800 bp DNA was digested into small fragments of less than 400 bp with restriction enzymes for the direct PCR-SSCP analysis. Firstly, 10 strains were analysed. All the 10 isolates showed clearly distinct SSCP patterns in Bkat from that of the reference strain, but only two isolates showed distinct SSCP patterns in Akat, and no isolated strain showed any distinct SSCP patterns in Ckat. 10 isolates also showed distinct SSCP patterns in inhA. NciI restriction mapping of Bkat showed mutation in codon 463 in 7 strains among 10 isolated strains. With these results an early detection strategy for the INH resistant M. tuberculosis was applied to the rest of 19 isolated INH resistant strains. Firstly, isolates were screened by Ncsl mapping in Bkat, and 13 strains showed mutations in codon 463. Secondly, the rest of 6 INH resistant isolates were analysed by PCR-SSCP with restriction enzyme digestion (PCR-SSCP-RE) in Bkat, and all the strains showed distinct SSCP patterns from that of the INH sensitive reference strain. This proved our strategy as effective and economic and time saving method in early detection of INH resistant M. tuberculosis.

We evaluated an effect of the distance between the incision line and corneal limbus on surgically induced astigmatism in sutureless cataract surgery with scleral tunnel incision. We made a 6mm scleral tunnel incision 1.0mm from the limbus (Group 1, 24 eyes) and 2.5mm from the limbus (Group 2, 30 eyes) and implanted polymethylmethacrylate (PMMA) intraocular lenses with a round optic of 6mm following phacoemulsification. We employed the Jaffe method and Cravy method of vector analysis to evaluate the change of Surgically induced astigmatism. The mean surgically induced astigmatism using Jaffe method was 1.24 D and 0.98 D one day after surgery in Group 1 and 2, respectively. The difference between them was statistically significant(p<0.01) and became insignificant(p>0.05) after postoperative one week. In the superior incision cases, the difference using Cravy method was not statistically significant for whole followup period. In the temporal incision cases, the surgically induced astigmatism was 0.39 D and 0.02 D one day after surgery in Group 1 and 2, respectively. The difference was statistically significant(p<0.05) and became statistically insignificant(p>0.05) after postoperative one week. In this study it was found that a distance of incision line from corneal limbus longer than 1 mm was not an important factor in influencing the surgically induced astigmatism one week after sutureless cataract surgery using a watertight scleral tunnel incision.
