Malignancy may cause variable musculoskeletal symptoms which resemble connective tissue disorder. This symptoms as a fine sign of hidden neoplasm can precede the diagnosis of underlying malignancy. But only one case of stomach cancer associated with cancer arthritis was reported in the world. This fact is very interesting in Asia which has high prevalence of stomach cancer. We experienced one case of gastric adenocarcinoma with oligoarthritis involving both knee and right elbow. A 48-year-old man was diagnosed stomach cancer by gastric endoscope and biopsy. After then, he complained pain, tenderness, heating sensation, swelling of both knee and right elbow with high fever. Both knee MRI showed abundant synovial effusion and soft tissue edema. Full dose of nonsteroidal anti-inflammatory drug was not effective to control fever and arthritis. But fever and arthritis were gone after resection of tumor.

Takayasu's arteritis is a chronic vasculitic disease of the aorta, its major branches and the pulmonary arteries, resulting in stenosing, occlusive or aneurysmal lesion. While the precise etiology of Takayasu's disease is unknown, an autoimmune mechanism or active tuberculous inflammation have been suggested. It is more common in young oriental women but has a rare incidence in children. We experienced a case of Takayasu arteritis type IV in an 8years old girl. The diagnosis was made by physial examination and digital substraction aortography(DSA) which showed narrowing of left common carotid artery, right subclavin artery and left renal artery. The perfusion defect at posterior segment of right upper lobe was noted in lung perfusion scan. Medical treatment and percutaneous transluminal angioplasty(PTA) were performed. In addition to case report, a brief review of literature was added.

PURPOSE: To evaluate the characteristic MR findings in injury of the anterior cruciate ligament (ACL) with associated bony lesions. MATERIALS AND METHODS: We reviewed MR findings and the corresponding arthroscopic or operative results of 48 patients with ACL injuries, and evaluated ACL signal intensity and contour. In associated bony lesions, we determined the location of avulsion fracture and bony bruise. RESULTS: Cmplete ACL tears were seen in 27 cases, partial tears in 13, and avulsion injury in eight. Complete tears showed heterogeneously increased signal intensity with contour bulging in ten cases (37 %), and combined bony lesion in 14 (52 %). ACL with a thin continous low signal intensity band surrounding heterogeneously-increased signal intensity suggested partial tears, and was seen in three of 13 proven cases (23 %) of partial ACL tears ; combined bony lesion was seen in four such cases (31 %). There were eight cases of avulsion fracture ; the most frequent site was the anterolateral portion of the tibial spine (n=6). The most frequent sites of bony lesion were at the midportion of the lateral femoral condyle (n=6), and the posterior portion of the lateral tibial plateau (n=6) ; the next most frequent site was the anterior portion of the lateral tibial plateau (n=5). CONCLUSION: Tearing of the ACL was seen on MRI as ligament discontinuity, and heterogeneously increased signal intensity with ACL contour bulging. The most frequent sites of associated bony lesions were the midportion of the lateral femoral condyle, and the posterior portion of the lateral tibial plateau. In associated bony lesions, bony contusion suggested ACL tearing, but avulsion fracture suggested ligament avulsion injury without tear.

PURPOSE: The purpose of this study was to compare two bowel preparation agents, sodium phosphate solution with magnesium citrate solution. MATERIALS AND METHODS: A total of 94 subjects that underwent a double-contrast barium enema were included in this study. Bowel preparation before performing the barium study was done by using a sodium phosphate solution in 47 subjects and by using a magnesium citrate solution in the other 47subjects. We evaluated the presence or absence of side effects when using these bowel preparation agents. Two radiologist who were blinded to the type of bowel preparation evaluated the quality of bowel preparation at the colonic segments (ascending, descending, and sigmoid colon) on the radiographs obtained by double-contrast barium enema, with regard to stool cleansing, water retention, barium coating and bubble formation. RESULTS: The side effects, such as abdominal clamping pain, nausea, hunger pain and chill occurred more frequently in the sodium phosphate group than in the magnesium citrate group (p<0.001). Stool retention was more frequently found in the magnesium citrate group (p<0.001). However, no statistical difference was noted on the status of water retention and barium coating between two groups. Gas bubble formation was more commonly seen in the sodium phosphate group (p<0.001). The sodium phosphate solution appeared to be more effective in cleansing the right colon (p=0.001). CONCLUSION: Sodium phosphate solution appears to be more effective for colonic cleansing, with a lower incidence of side effects, than when using magnesium citrate solution.

Metastatic tumors occur more frequently in the liver than in any other organ, Guided percutaneous fine-needle aspiration (FNA) of the liver is often recommended for confirmative diagnosis of the metastatic lesion, because of its simplicity, high yield, and reasonable safety. The authors studied retrospectively cytologic findings of 110 cases of metastatic tumors to the liver. The frequent primary sites were the stomach (23 cases), pancreas (19 cases), gallbladder (12 cases), and periampullary lesions (6 cases). Most of the metastases were carcinoma (106 cases). There were only 4 cases of sarcoma. The characteristic cytologic findings of FNA of meatastatic tumors were dirty background, abrupt change between hepatocytes and malignant cells, and desmoplasia. Some tumors displayed rather distinctive cytologic appearance that suggests primary sites. For example, the colonic adenocarcinoma showed tall columnar cells with a palisading arrangement, adenocarcinoma of gallbaldder showed focal squamous differentiation in some cases, and metastatic renal cell carcinoma and neuroblastoma showed also distinctive cytologic findings. Because the cytologic features of metastatic tumor are very similar to those of primary tumor, correct cytologic typing may be helpful in pursuit of an occult primary site of metastatic liver lesions, reducing extensive diagnostic investigation in poor prognostic patients.

In order to observe the changes in left ventricular function during coronary artery occlusion and reperfusion, left anterior descending (LAD) coronary arteries in the anesthetized dogs were occluded for 1 hour and then reperfused for 4 hours. Hemodynamic indexes of global systolic and diastolic function and regional wall thickness changes as a regional contractile index were measured during occlusion and reperfusion. The results were as follows; 1) Indexes of global systolic function (left ventricular peak systolic pressure, peak positive dP/dt) and global diastolic function (peak negative dP/dt, time constant, left ventricular end-diastolic pressure) showed deterioration in early occlusion period (10-30 minutes) but gradually improved even if coronary occlusion persisted. Reperfusion did not induce significant changes except that peak positive dP/dt transiently deteriorated 30 minutes after reperfusion and left ventricular end-diastolic pressure decreased 1.5-2 hours after reperfusion. 2) Indexed of regional function (i.e, end-diastolic thickness and % systolic thickening of anterior left ventricular wall) deteriorated by 10 minutes' occlusion which persisted during the entire occlusion period. Reperfusion induced no significant improvement in regional contractile function compared with occlusion 60 minutes' data, which suggested reperfusion for 4 hours after 1 hour's LAD occlusion may be insufficient for the ischemic region to recover its contractility. 3) Reperfusion arrhythmia (ventricular tachycardia) was noted in most (6/9) of the dogs, one of which deteriorated into ventricular fibrillation and the others spontaneously converted to normal sinus rhythm.

A previous animal study has shown the effects of erythropoietin (EPO) and its non-erythropoietic carbamylated derivative (CEPO) on neurogenesis in the dentate gyrus. In the present study, we sought to investigate the effect of EPO on adult hippocampal neurogenesis, and to compare the ability of EPO and CEPO promoting dendrite elongation in cultured hippocampal neural progenitor cells. Two-month-old male BALB/c mice were given daily injections of EPO (5 U/g) for seven days and were sacrificed 12 hours after the final injection. Proliferation assays demonstrated that EPO treatment increased the density of bromodeoxyuridine (BrdU)-labeled cells in the subgranular zone (SGZ) compared to that in vehicle-treated controls. Functional differentiation studies using dissociated hippocampal cultures revealed that EPO treatment also increased the number of double-labeled BrdU/microtubule-associated protein 2 (MAP2) neurons compared to those in vehicle-treated controls. Both EPO and CEPO treatment significantly increased the length of neurites and spine density in MAP2(+) cells. In summary, these results provide evidences that EPO and CEPO promote adult hippocampal neurogenesis and neuronal differentiation. These suggest that EPO and CEPO could be a good candidate for treating neuropsychiatric disorders such as depression and anxiety associated with neuronal atrophy and reduced hippocampal neurogenesis.
