Failure of fixation of intertrochanteric fractures that have been treated with a fixed-angle sliding hip-screw device is frequently related to the position of the lag screw in the femoral head. The purpose of this study is to introduce the concept of the tip-apex distance and to demonstrate its clinical usefulness as a predictor of cutout of the screw used for fixation of the intertrochanteric fractures of the hip. The tip-apex distance is the sum of the distance from the tip of the lag screw to the apex of femoral head on an anteroposterior radiograph and this distance on a lateral radiograph after controlling for magnification. To determine the value of tip-apex distance in the prediction of cutout of the lag screw, 67 intertrochanteric fractures that have been treated with a fixed-angle sliding hip screw device were studied. The minimum duration of follow-up was three months during which period all of the fractures either healed or had failure of the fixation. The average tip-apex distance was 21mm (range,22.8-65.8mm) for the successfully treated fractures compared with 35mm (range,8.4-65.8mm) for those in which the screw cutout. There was strong statistical relationship between an increasing tip-apex distance and the rate of cutout. An unstable fracture, a poor reduction were also associated with a significantly increased risk of failure due to cutout.

The emergency arteriography have been performed in a total of 13 patiens with extermity trauma, including 9fractures, 3 blunting traumas, and 1 penetrating injury. over 17 months period. The indications were as follows:absent or diminishe pulse, swelling, sensory or motor deficit , and hypotension. Patients with an absent pulse,the most reliable indication of arterial injury, should have immediate arteriography. The superficial femoralartery was commonly injured especially with distal femoral shaft fracture. The most common arteriographic findingswas arterial occlusion.

Sialosyl Tn mucin antigen (STn) is a carbohydrate antigen of tumor associated mucin formed by the premature 2~6 sialation of N-acetylgalactosamine. STn has been expressed in several tumor types and showed prognostic significance in colonic carcinoma. The authors evaluated the expression of STn immunohistochemically and correlated its expression with clinicopathologic variables in 100 gastric cancers. In early gastric cancer, STn was expressed in 24 cases out of 50 cases (48%). In advanced gastric cancer, STn was expressed in 48 of 50 (96%). The difference in STn expression between advanced gastric cancer and early gastric cancer was statistically significant. The difference in STn expression between tumors with lymph node metastasis and those without lymph node metastasis, between tubular adenocarcinoma and signet ring cell carcinoma, and between intestinal type and diffuse type adenocarcinoma was statistically insignificant in early or advanced gastric adenocarcinoma. These results suggest that the STn expression plays a role in the tumor progression in both early and advanced gastric adenocarcinomas.

PURPOSE: To assess the value of MR imaging compared to CT for the staging of gastric carcinoma when body-wrap-around surface coil, intravenous glucagon, motion suppression technique and effervescent granules are used. MATERIAL AND METHOD: CT and MRI were performed for thirty-five patients with gastric carcinoma. Postcontrast CT scan was performed immediately after oral effervescent granules and Buscopan were given. Before MR imaging, BWA surface coil was wrapped around the upper abdomen. T1 coronal, sagittal and axial SE images (TRITE=400/15 msec) were obtained immediately after oral effervescent granules and glucagon were given. Respiratory compensation and presaturation techniques were used for each imaging. Three radiologists evaluated independently for randomly mixed 70 sets of CT and MR images. The signal intensity of gastric mass and enlarged lymph nodes were compared to the signal intensity of the adjacent pancreas, liver and spleen to evaluate any discriminating features between them. RESULTS: The accuracy in the diagnosis of pancreatic invasion was 83.8% on MRI and 74.3% on CT (p < 0.05). The accuracy of MRI and CT was 77.1% and 72.4% in detecting of gastric tumor respectively (p > 0.05), 73.3% and 68.6% in gastric serosal invasion (p> 0.05), 50.5% and 42.9% in lymph node metastasis (p > 0.05). The gastric mass and enlarged lymph nodes were hypointense to the intensity of pancreas and liver in more than 78% of cases. CONCLUSION: MRI was comparable to CT scan for the staging of gastric carcinoma. Therefore, MRI could be used as an alternative or adjunctive diagnostic modality in the staging of gastric carcinoma.

Korean Journal of Clinical Pathology 2001;21(3):204-209
BACKGROUND: Recently malaria infection became one of the most important parasitic diseases in Korea. After the re-emergence of malaria in a young soldier in 1993 near the De-Militarized Zone (DMZ), three to four thousand people have been infected per year in the last few years and the cases of infection have been increasing threefold each year. Microscopic examination of a thick blood smear is a conventional and confirmatory method for diagnosis. However, it requires labor-intensive procedures and its interpretation is quite subjective. Faster and more reliable methods are needed for the diagnosis of malaria. METHODS: We evaluated 155 patients who were diagnosed as malaria. We performed point-of-care rapid diagnostic methods recently introduced: two antibody detection tests manufactured by Korean companies and one antigen (Plasmodium lactate dehydrogenase, pLDH) detection test. The results were compared with those of microscopic examinations of thick blood smears. RESULTS: Sensitivities of two antibody detection assays and one antigen detection assay in acute attacks of malaria were 64.7%, 72.5%, and 96.1%; and, specificities were 88.5%, 89.4%, and 95.1%, respectively. Overall accuracy for all samples were 80.6%, 83.9%, and 95.5%, respectively. CONCLUSIONS: Antibody detection tests for malaria have limitations in sensitivity and accuracy to replace microscopic examination of blood film. Antigen tests detecting pLDH could replace conventional microscopic examinations of blood film, especially in emergency situations in cases that require prompt medication.

From March 1987 to July 1989, six patients (five dadults and one child) with lung abscess (size, 5-13cm in diameter) were treated with percutaneous aspiration and drainage. In each case, the puncture was made where the wall of the abscess was in contact with the pleural surface. An 8 to 10 Fr catheter was inserted for drainage. Five of 6 had a dramatic clinical response within 24 hours of the drainage. Percutaneous drainage was successful with complete abscess resolution in four and partial resolution in one patient. No response was seen in the rest one. The duration of drainage ranged from 7 to 18 days (average, 15.5days) in successful cases. One case of the failure in drainage was due to persistent aspiration of the neurologically impaired patient. In one patient, the abscess resolved after drainage but recurred after inadvertent removal of the catheter 7 days after insertion. In two patients, concurrent pleural empyema was resolved completely by the drainage. Computed tomography provided anatomic details necessary for choosing the puncture site and avoiding a puncture of the lung parenchyma. Percutaneous catheter drainage is a safe and effective method for treating patients with lung abscess.

Recently short term chemotherapy has become popular for the treatment of genitourinary tuberculosis. But it is questionable weather short term chemotherapy can cure all cases of genitourinary tuberculosis regardless of their severity ;and the role of nephrectomy in patients with renal tuberculosis is still controversial. Herein we analyzed 52 patients with confirmed urinary tuberculosis who were treated with triple drugs, including isoniazid, rifampicin and ethambutol, for 6 to 9 months. The patients ranged from 13 to 71 years of age, and the male to female ratio was 2.4: 1. Follow up period ranged from 6 to 65 months with a mean period of 19.7 months. The patients were classified according to the severity of renal tuberculosis on pyelography into Group I ( minimal, 8 patients), II (moderate, 9 patients) and III (severe, 35 patients), and treatment result were analyzed in each group. Of 52 patients, 19 were treated by chemotherapy only and 33 (63.5%) reconstructive surgery. Success rates of short term chemotherapy in terms of cure of tuberculosis and preservation of functional renal tissue were :overall 75%, 100% in Group I , 77% in Group II and 68.6% in Group III. Two of 9 patients in Group II and 10 of 17 in Group III who were treated with chemotherapy only, deteriorated with loss of the kidney. Poor vascular pyonephrotic kidney and progressive ureteral stricture were suggested as the main cause of failure. Ureteroneocystostomy and double J enting were helpful not only in the preservation of the kidney but also in the rapid cure of a renal tuberculosis. 24 patients who were treated with 6 to 9 months chemotherapy after removal of their nonfunctioning kidney were relapse-free on follow up. In conclusion, 6 to 9 months chemotherapy is adequate minimal urinary tuberculosis. For the treatment of moderate to advanced urinary tuberculosis, a longer period of chemotherapy may be adequate, and meticulous follow up with IVP and aggressive management of ureteral stricture is essential. A far advanced, nonfunctioning, unilateral tuberculosis kidney is better to be removed early, followed by 6 to 9 months' chemotherapy.
