Internal hernia is an unusual cause of the intestinal obstruction. The advances of CT make the diagnosis more easier than in the past. We report one case of internal hernia with herniation of the ileum into the lesser omenturn. The diagnosis could be made when abdominal radiographs showed fixed clustering of the small bowel loops in upper abdomen medial to the stomach. CT and ultrasound showed characteristic interposition of the ileum between the left hepatic lobe and the stomach.

PURPOSE: The purpose of this study is to assess the sonographic findings of Osgood-Schlatter disease with correlation to radiographic findings and to determine value of sonography in the diagnosis of Osgood-Schlatter disease. MATERIALS AND METHODS: The population consist of 22 cases of Osgood-Schlatter disease and 15 healthy subjects of the same age range for comparison. The sonographic study was carried out with real time units equipped with linear probe of 7 MHz frequency. Radiography and sonography were done in all cases and follow-up sonography was performed in 10 cases. RESULTS: The sonographic features of the Osgood-Schlatter disease were swelling of cartilage over the anterior tibial tuberosity ossification center in 16 cases, fragmentation and/or irregularities of the ossification center of the anterior tibial tuberosity in 14 cases, localized thickening of the pateliar tendon in 14 cases, ossicles in the thickened pateliar tendon in 3 cases, and distension of the infrapatellar bursa in 2 cases. Fifteen of 22 cases of Osgood-Schlatter disease had abnormal findings on radiographs and sonograms. Out of 7 cases which had normal radiograph and abnormal findings on sonogram, 6 cases showed pateliar tendon thickening, cartilage swelling, and/or distended infrapatellar bursa and one case showed fragmentation of anterior tibial tuberosity on sonogram. CONCLUSION: Sonographic evaluation of Osgood-Schlatter disease provided a clear picture about pathologic changes in the superficial soft tissues and in the cartilage and also yielded the same diagnostic information on bony change as radiography Sonography is a reliable and useful method for the evaluation of young patients with clinically suspected Osgood-Schlatter disease.

Primary renal lymphoma is a rare tumor of the kidney that typically presents with bilateral nodular enlargement in the absence of extrarenal masses. We describe MR findings of a case of primary renal lymphoma along with ultrasound and CT findings. MR imaging demonstrated globular enlargement of both kidneys with multilobulated contour and multiple masses which had isosignal intensity on T1WI and low signal intensity on T2WI. The masses enhanced slightly on dynamic contrast enhanced scan.

PURPOSE: To evaluate the usefulness of double injection of a vasoactive drug in penile Doppler ultrasonography for the diagnosis of vasculogenic impotence. MATERIALS AND METHODS: Eighty-four consecutive cases (bilateral sides) of 42 patients with suspected vasculogenic impotence were included in our study. We used computed sonography (Acuson, USA), with a 7 MHz linear array transducer. After the first intracavernosal injection of the vasoactive drug (10 ug of prostagladin E1), peak systolic velocity (PSV) and end diastolic velocity (EDV) were measured three times. According to mean PSV and EDV, the patients were classified into four groups : arteriogenic impotence (AI;N=29), venogenic impotence (VI;N=28), AI associated with VI(N=14), and normal(N=13).After the second injection, PSV and EDV were remeasured, using the same method. Mean velocities of the first injection were compared with those of the second, and the paired t-test was used to analyze the results. the extent to which patients were reclassified after the scecond injection we noted. RESULTS: In all four groups, PSV measured after the second injection was significantly different from PSV after the first (p=0.0001, 0.0001, 0.0010, 0.0072); except in the normal group, EDV measured after the second injection was not different from EDV after the first (P=0.9815, 0.0654, 0.0950, 0.0057). After the second injection, the numbers of patients reclassified into other groups were as follows : AI, 11 (38%); VI, 6 (21%); AI associated with VI, 11 (79%); normal, 1 (8%). CONCLUSION: Double injection of a vasoactive drug affected PSV, and therefore, appears to be a useful adjunctive procedure for the evaluation of patients in whom classification based on the results of the first injection is difficult.

OBJECTIVE: The purpose of this study is to evaluate the efficacy of ferritin-folate-cyanocobalamin supplementation for prevention of anemia during pregnancy. METHODS: The authors conducted a clinical investigation on 50 pregnant women from 20th to 36th gestational weeks. The cobination of cyanocobalamin coenzyme 500mg, folic coenzyme 800mcg, and ferritin 20mg constituted the supplementation. The parameters examined in first trimester as baseline, before treatment(at 20th weeks), and after treatment(at 36th weeks) were : hemoglobin, hematocrit, ferritin, mean corpuscular hemoglobin(MCH), mean corpuscular hemoglobin concentration(MCHC), mean corpuscular volume(MCV), red blood cell count(RDW), folic acid, and vit. BPaired sample t-test was used for comparison. RESULTS: The results indicated a significant increase in the value of hemoglobin(p<0.05) and hematocrit(p<0.01) in comparison to before and after the treatment. The values of serum ferritin, folic acid, vitamin Bwere increased after the treatment compared to those of before the treatment, though there was no statistical significance. The results of MCV, MCH, MCHC, and RDW showed no statistically significant in comparison to before and after the treatment. CONCLUSIONS: These data indicate that supplementing ferritin 20mg-folate 800mcg-cyanocobalamine 500mcg per day from 20th to 36th weeks' gestation can increase values of hemoglobin, hematocrit, and ferritin concentration and can be cosidered as an appropriate method to prevent iron deficient anemia. It also might increase the value of folic acid and vitamin B12, concentration, but further study is stiU needed to determine whether the supplementation of folate and cyanocobalamine in combination with iron can have better eflicacy than iron alone in prevention of iron deficiency anemia.

The origins of medullary carcinoma (MTC) and papillary carcinoma (PTC) of the thyroid are embryologically different. Tumors showing concurrent medullary and papillary features are rare and they represent less than 1% of all thyroid malignancies. Hereditary MTC is an autosomal dominantly inherited disease which is genetically determined as part of the MEN 2A, MEN 2B, or variants of MEN 2A such as familial MTC. Germline mutations of the RET gene are the underlying cause of the majority of cases of hereditary medullary carcinomas. The pathogenesis of concurrent PTC with familial MTC has rarely been known. Genetic analysis of the RET oncogene has so far provided conflicting results. Here we describe a family whose sibling was affected by both PTC & MTC, and the family carried a germ-line point mutation in the RET extracellular domain that converted cysteine 634 into tryptophan (C634W).

Pulmonary mucormycosis is a relatively rare but highly virulent and rapidly progressive disease that occurs after inhalation of spores of the fungi that belong to class Zygomycetes. This infection occasionally occurs in seriously immunocompromised patients, but also in patients with uncontrolled diabetes or diabetic ketoacidosis. Diagnosis is pathologic demonstration of typical hyphae within lung tissue, and requires aggressive treatments including surgical and medical approach for reducing the overall mortality. In Korea, pulmonary mucormycosis complicated with diabetes has been reported in only five cases. Recently, we experienced a case of pulmonary mucormycosis in 32-year-old poorly controlled diabetic man, who had nonspecific pulmonary symptoms, a lobar consolidation on chest radiograph, and endobronchial lesions on bronchoscopic finding. We reported here our case and reviewed characteristics of other five previous cases.

PURPOSE: MR cholangiography(MRC) in patients with obstructive biliary diseases was evaluated in order to compare its role with that of ERCP or PTC. MATERIALS AND METHODS: Twenty consecutive patients with obstructive biliary and peribiliary diseases (Eleven biliary and peribiliary carcinomas, seven intrahepatic stone diseases and seven extrahepatic stone diseases) were included and ERCP(16 ccases) or PTC(four cases) was performed in all twenty cases. Non-breasth-hold, heavily T2-weighted, fast spin echo MRC was carried out and 2-D axial, coronal images and 3-D images with maximum intensity projection protocol were obtained. We regarded ERCP or PTC as thegold standard and then comparedn MRC with ERCP of PTC retrospectively. RESULTS: In 11 patients with biliary and peribiliary carcinomas, the level of obstruction was depicted in nine cases(83%) on MRC and in six of seven cases(86%) on ERCP. The causes of obstruction were demonstrated in eight cases(73%) on MRC and in six of seven cases(86%) on ERCP. On MRC, Seven cases(64%) revealed similar findings to ERCP or PTC. Of seven cases of EHD and seven of IHD stone diseases, EHD stones were detected in six cases(86%) on MRC and in seven cases (100%) on ERCP,IHD stones were detected in four cases(57%) on MRC and in five cases(71%) on ERCP. 2D-MRC was superior to 3D-MRCin the detection of stones. The extent and grade of ductal dilatiation was accurately revealed in six cases(86%)on MRC and in seven cases(100%) on ERCP of EHD stones, in six cases(86%) on MRC and in three cases(43%) on ERCP of IHD stones. Six cases(86%) of EHD stones and two cases(29%) of IHD stones revealed similar findings between MRCand ERCP. CONCLUSION: MRC findings were similar to those of ERCP or PTC in the evaluation of malignant biliary diseases or extrahepatic stone diseases and was valuable in their diagnoses. In the evaluation of intrahepaticstone diseases, MRC demonstrated dilated peripheral IHDs with stones more difinitely than ERCP but in the detection its accuracy was low. Further studies may therefore be needed.
