Biliary ascariasis is a rare complication of intestinal ascaris infestation. Retrograde migration of the adult worm through the papilla of Vater causes biliary colic, and may give rise to pancreatic and biliary obstruction, choledocholithiasis, cholecystitis, cholangitis, hemobilia, and if the worm lodges in intrahepatic bile ducts, to liver absceases. In the past, treatment of biliary ascariasis has usually involved the direct removal of ascaris throagh a surgical choledochatomy and subsequent saline lavage of the common duct through an indwelling T tube. Recently, the worm in the bile duct can be seen by ERCP and it can be removed during the endoscopic procedure. A 55-year-old woman with intermittent colicky right upper quadrant abdominal pain was admitted to out hospital. Abdominai sonogram disclosed an echogenic structure within a mildly dilated common bile duct and a high ehogenic structure with acoustic shadowing in the distal common bile duct(CBD), which suggests a CBD stone. ERCP after obtaining the sonogram revealed a thick, long, linear, smooth filling defect in the CBD with a distal CBD stone. A distal CBD stone was removed by sphinctetotomy and lithotripsy, then we directly extracted ascaris with a tripod forcep without any complication.

PURPOSE: To determine clinical outcome in cases of traumatic intraventricular hemorrhage(TIVH) according to the mechanisms and amount of hemorrhage seen on initial CT. MATERIALS AND METHODS: We retrospectively reviewed the initial CT findings of 61 patients with TIVH. The mechanisms of TIVH were analyzed on the basis of the following CT findings: Type I; large intracerebral hematoma extending to adjacent ventricle; Type II: hemorrhagic and/or non-hemorrhagic diffuse axonal injury in the thalamus and basal ganglia; Type III: multiple small hemorrhagic lesions in the septum pellucidum, fornix, corpus callosum, and periventricular region, which may be due to inner cerebral trauma, Type IV: evidence of hypoxic brain injury, and Type V: TIVH with contusion and small subdural or epidural hematomas. The amount of TIVH was classified according to the Graeb score. We analyzed these mechanisms on the basis of CT findings, and for prognosis, correlated these with clinical outcomes and the Glasgow coma score. RESULTS: Prognosis was good in types V and III and poor in type I and II(p=0.001). In patients with a Graeb score of 4 or less, the clinical outcome was better than in those with a Graeb score above 5(p=0.03). Patients with a lower initial Glasgow coma score had poor outcomes(p=0.001). CONCLUSION: The hemorrhage mechanism in patients with TIVH could be important for estimating clinical outcome, especially during the early phase. In patients with type V or III TIVH, clinical outcome was better than in those with type I or II.

BACKGROUND: Overt hypothyroidism is a well-known cause of secondary hyperlipidemia and atherosclerosis. However, there have been some dissenting report of abnormalities and in serum lipid concentration in patients with subclinical hypothyroidism. We have attempted to analyze serum lipid concentrations to investigate whether they are increased in patients with subclinical hypothyroidism and to see if there is a correlation between serum LDL-C and TSH concentrations. METHODS: Serum lipid profiles(total cholesterol, triglycerides, LDL-C, HDL-C) of patients with subclinical hypothyroidism (M/F=7/119) compared with age, sex and body mass index matched control subjects(M/F=14/239) from Jan. 1 . 1996. to Dec. 30. 1997. RESULTS: There were no significant differences of serum total cholesterol, LDL cholesterol, TG, and HDL concentrations in 126 patients with subclinical hypothyroidism and 253 control subjects(178.47+/-35.76mg/dL vs. 173.05+/-35.93mg/dL ; 113.33+/-52.89mg/dL vs 117.64+/-68.70mg/dL ; 112.89+/-33.26mg.dL vs 109.65+/-29.02mg/dL ; 48.60+/-11.34mg/dL vs 46.51+/-11.73mg/dL). There was no correlation between LDL cholesterol and TSH concentrations in subclinical hypothyroidism(r=0.29, p<0.05). CONCLUSION: Serum lipid concentration (total cholesterol, LDL cholesterol, and TG, HDL) was not increased in patients with subclinical hypothyroidism. There was no correltion between serum LDL and TSH levels in patients with subclinical hypothyroidism.

We experienced anaphylaxis during general anesthesia twice in the same patient. After the first incidence of anaphylaxis at the induction of anesthesia, we speculated that the allergen was rocuronium. Thus, we administered sugammadex as well as a vasopressor to treat the anaphylaxis and the vital signs gradually recovered to nearly normal. Thereafter, we could not avoid the administration of another muscle relaxant, cisatracurium, since the patient moved uncontrollably after the surgery was restarted. A second anaphylactic event then occurred. We speculated that the second allergen was cisatracurium and stopped using it. The results of the investigation after the surgery showed that the allergens were indeed rocuronium and cisatracurium. When we encounter anaphylaxis during general anesthesia, it is necessary to suspect all administered medicines as the cause, with the potential of two or more causes, especially with muscle relaxants.

PURPOSE: To evaluate the usefulness and diagnostic accuracy of turbo spin-echo(TSE) proton-density andT2-weighted images of meniscal tears of the knee. MATERIALS AND METHODS: We retrospectively evaluated thesensitivity, specificity, and accuracy of TSE proton density and T2-weighted images of meniscal tears confirmedarthroscopically or surgically in 47 patients(98 menisci). The routine TSE parameters used in all patients werethe dual echo sequence with sagittal proton density and T2-weighed images(4000/16, 90/5/2 [TR/effectiveTE/ETL/NEX]), and fat-suppressed coronal proton density and T2-weighted images. The chi-square test was used forstatistical analysis. RESULTS: The sensitivity, specificity, and accuracy of TSE proton density images for thedetection of meniscal tears were 93.9%, 93.8%, and 93.9%, respectively, in the medial meniscus, and 92.9%, 91.4%,and 91.8% in the lateral. On T2-weighted images the corresponding figures were 87.9%, 93.8%, and 89.8%,respectively, in the medial meniscus, and 64.3%, 91.4%, and 83.7 % in the lateral. CONCLUSION: With regard tosensitivity and accuracy, TSE proton density images of meniscal tears were superior to TSE T2-weighted images.

BACKGROUND: Aortic intramural hemorrhage (IMH), which presents clinical manifestations identical to acute aortic dissection, is suggested to have different pathology and pathophysiology. The purposes of this study were to diagnose IMH by transesophageal echocardiography (TEE) prospectively and to compare clinical and echocardiographic outcome of IMH with those of aortic dissection. METHODS: Between August 1991 and November 1996, 27 IMH and 73 acute aortic dissection were diagnosed using TEE in 202 consecutive patients with suspected aortic dissection. TEE diagnoses of IMH and aortic dissection were initially compared with computed tomography and magnetic resonance imaging and later confirmed by operative findings (n=39) or follow-up changes (n=12). RESULTS: In the 49 patients whose diagnosis was confirmed by operation or follow-up changes, the sensitivity and specificity for the diagnosis of IMH were 27 of 27 (100%) and 20 of 22 (91%), respectively. There were 11 deaths (15%) in acute aortic dissection and 1 death (4%) in IMH during follow-up of 1.7+/-1.5 years (p=NS). Stanford classification and types of treatment were not related to death in both groups. Complications were less frequently noted in IMH (3/27) than in acute aortic dissection (24/73) (p<0.001) and no death occurred in uncomplicated IMH who were medically treated. Follow-up study of 12 IMH patients showed 8 complete resolution, 3 regression, 1 progression. CONCLUSION: TEE is very useful in diagnosis of IMH and IMH has better outcome than the aortic dissection due to absence of communication and intimal tear.

BACKGROUND: Although lung involvement has been reported in 5 to 46% of dermatomyositis/polymyositis (DM/PM) patients, reports of the condition in Korea are rare. This study evaluated the clinical features of lung involvement in DM/PM patients. METHODS: The medical records, laboratory results and radiologic findings of 79 DM/PM patients, who attended the Seoul National University Hospital (SNUH) between 1989 and 1999, were reviewed retrospectively. RESULTS: A total 79 patients of whom 24 patients(33%) showed lung involvement, were enrolled in this study. More patients with lung involvement were female(F:M=11:1), and older compared with those without lung involvement. Patients with lung involvement presented with dyspnea(79%), coughing(67%), an elevated ESR, and CK/LD. Anti-Jo 1 antibody test was positive in 30%, which is significantly higher in patients with lung involvement. A simple chest X-ray of the patients with lung involvement exhibited reticular opacity(50%), reticulonodular opacity(30%), patchy opacity(29%), nodular opacity(13%) and linear opacity(4%). HRCT(n=24) showed ground glass opacity(75%), linear or septal thickening(50%), patchy consolidation(42%), honey-combing(33%) and nodular opacity(17%). The pulmonary function test showed a restrictive ventilatory pattern(77%) and a lower diffusing capacity(62%). The patients were followed up during a mean duration of 30±28 months. They were treated with steroid only(50%) or a combination of steroids and cytotoxic agents(46%). Muscle symptoms were improved in 89% with treatment, but an improvement in the respiratory symptoms or in the pulmonary function test was rare. Patients with lung involvement had a higher mortality rate(21%) than those without lung involvement(10%) during the follow-up periods. CONCLUSION: DM/PM patients with lung involvement were mostly female, older and had a higher positive rate Anti-Jo 1 antibodies, but there was no significant difference in prognosis.
