BACKGROUND: Korea is, known to be an endemic area of viral hepatitis B, and 5-6% of population are carriers. Immunization can reduce the spread of hepatitis B infection. Hower, not all people respond to hepatitis B immunsation. 5-15% of primary vaccinees fail to be immunized. After revaccination, only 37.5 44% of the primary failures elicit antibody response. Recent studies have reported that it is effective to inject a double dose vaccination in immunocompromsed patients. In some country, they recommend that neonate whode mother is HBV carrier shoud receive double dose vaccination. This study documented the results of double dose vaccintion only once to nonrsponders toward the HBV immunzation. METHODS: Healthy nonresponders to Hepatitis B immunization were recuited from Sep. 1995 to Aug. 1996. Subjects with their AST/ALT level over 40, or over 65 years old were excluded. They were received 2ml of plasma-derived vaccine(Hepavax-B) intramuscularly in the deltoid muscle. Anti-HBs antibody testing were performed at 1 to 3 months after vaccintion. RESULTS: 17 healthy nanreponders to Hepatitis B immunization(male 10, female 7) were included. Their mean ages were 47(32 to64), AST/ALT level 20/19(16 to 28/11 to 35), smoking 4.3pys(1 to 7). Seroconversion occured in 13 of them(76.5%). CONCLUSIONS: Nonresponders to Hepatitis B vaccintion respond well to double dose vaccination once.

PURPOSE: Classically air in the portal vein has been detected on plain radiography, but computed tomography and ultrasonography have been shown to be more sensitive. We report a case of air in the PV in a 10-day-old infant with pneumatosis intestinalis with its ultrasonographic and Doppler findings. MATERIAL AND METHODS: The patient was a 10-day-old infant born by cesarean section at 41 weeks. Simple abdomen film revealed branching pattern of radiolucent air shadows within the contour of liver, gas distention of bowel loops and thickenod bowel walls with lincar intraluminal air shadows in abdomcn, suggesting neerotizing enterocolitis. So we performed Doppler ultrasonography. RESULTS: Ultrasonography showed branching pattern of hyperechogenic dots along the lumen of left portal vein. The color Doppler study revcaled an aliasing duo to increased velocity and whirling pattern of blood flow, and the Duplex Doppler spectral display showed sharp, vertical bidirectional spikes by air in portal vein. CONCLUSION: Air in the portal voin can be easily diagnosed by the followign signs:hyperechogenic dots in the portal vein on ultrasonography and vertical, sharp bidirectional spikes superimposod on the usual Doppler tracing of the portal vein on Duplex ultrasonography.

Opacification of the gallbladder after parenteral administration of contrast material usually indicates diminished renal function but can occur with normal renal function. The authors recently experienced 13 cases of such vicarious excretion of contrast media. Among 13 patients. 9 patients had renal disease unilateral ureteral stone(n=3), staghorn calculi(n=2), acute renal failure from sepsis(n=1), renal contusion(n=2) and unilateral renal artery involvement by dissecting aortic aneurysm(n=1). Of these 9 patients, 3 patients showed abnormal serum creatinine levels at the time of presentation or shortly thereafter. In 6 patients, injection of a large amount of contrast media was possibly the additional cause of vicarius excretion. There was no detectable cause in the remaining 4 patients. Heterotopic excretion of contrast media is clearly a complex phenomenon, the reason for which it is difficult to establish with certainty in each individual case. Anyhow, vicarius excretion of contrast media occurs more frequently than previously thought, and it can occur not only with abnormal renal function but with normal function also.

The indication of CT for the breast lesions are 1) Unusually extensive or small breast caused technicaldifficulties in performing mammograms. 2) Questionable mammographic findings, especially in dense proliferativebreast parenchyme, 3) Microcancer. 4) Suspicious regional lymph node enlargement of invasion of the chest wall bybreast cancer. The diagnosis of breast CT in breast cancer is based on pathologic anatomic change andcharacteristic increase of mean CT No. of lesion following contrast enhancement. Authors analysed CT of the 34patients who were clinically suspected breast cancer, and compared with mammography. The results are as follows:1. Pathological diagnosis of 34 cases were 27 cases of breast cancer, 4 cases of fibrocystic disease, 2 cases offibroadenoma, and 1 case of intraductal pupilloma. The diagnostic accuracy of CT in 27 breast cancer was 93%(25cases) and mammography 71%(19 cases). 2. Corect diagnosis of CT in 7 benign breast disease is in 5 cases andmammography in 5 cases. 3. The most importment finding of CT in breast cancer is characteristic increase of CT No.of lesion following contrast enhancement (200ml, 65%): over average 50HU in 19 cases of 27 breast cancers, 30-50HUin a 6 cases, 20-30HU in 2 cases with tumor necrosis. 4. Compared with mammography, other more valuable CTfindings of breast cancer are axillary lymph node enlargement and adjacentic pectoral muscle invasion. 5. Inconclusion, Breast CT is considered as a valuable diagnostic tool in evaluation of breast cancer, but not of benign breast disease.

Segmental Spinal Instrumentation(S.S.I.) is more effective means of managing unstable thoraco-lumbar spine fractures than traditional Harrington Rod Instrumentation as an operative procedure which afforded rigid internal fixation with stability and needed minimal external immobilization. Early return to normal activity and successful rehabilitation are facilitated by efficient stabilization with S.S.I. Fifty-nine patients with fractures and fracture-dislocations of thoraco-lumbar spine were treated by Harrington Rod Instrumentation (29 patients) and S.S.I. (30 patients) at this hospital from June 1979 to July 1984. We have analysed the results of these treatment and obtained following conclusions: 1. S.S.I. is more rigid internal fixation than Harrington Rod Instrumentation. a) no or minimal external immobilization b) early ambulation and rehabilitation c) lowered complications 2. There was no significant difference in correction rate, loss of correction, and neurologic recovery between Harrington Rod Instrumentation and S.S.I.

Recently, the number of reports of Acanthamoeba keratitis has been increased apparently as a consequence of association with use of contact lenses, contaminated contact lens care system and high concern of ophthalmologist to Acanthamoeba keratitis. But, there were few epidemiologic studies of contamination of contact lens care system by Acanthamoeba and there was no report in Korea. We carried out a survey to demonstrate the contamination of contact lens care system by Acanthamoeba and bacteria and analysed the results according to the types of contact lenses and methods of disinfection. We examined the contact lens care system of 185 asymptomatic contact lens wearer for the contamination of Acanthamoeba and bacteria. The result showed a significant contamination of Acanthamoeba and bacteria. Twenty eight(15%) were contaminated with Acanthamoeba, eighteen(10%) were mixed with bacterial contamination and seventy four(40%) were contaminated with bacteria. There was no significant difference with sex and the result showed a lot of cocontamination with bacteria and amoeba and chemical disinfection showed a high Acanthamoeba contamination rate. Based on data from this and previous studies, the most of contact lens care system of contact lens wearer was contaminated with bacteria, amoeba and other microorganism. So, ophthalmologists should be concerned about Acanthamoeba contamination of contact lens care system.

To evaluate the normal range of articular disk postion, MRIs of 25 temporomandibular joints(TMJs) in 19 asymptomatic volunteers were analysed. On the closed mouth sagittal T1 weighted MRI the junction of the posterior band and bilaminar zone was within 10°anterior from the vertical line through the apex of condylar head in 19 (76%) lad within 20°in 23 (92%) TMJs. The intermediate zone of the articular disk was located between the posterior surface of articular eminence and the anterior surface of condylar head in 22 (88%) TMJs. We suggest that on the closed mouth sagittal MRI the junction of the posterior band and the bilaminar zone could be within 10°anterior from the vertical line through the apex of condylar head in asymptomatic Korean persons. If the junction is located more than 20°anterior from the vertical line or the intermediate zone is anterior to the anterior surface of condylar head it is suggested that the disk is anteriorly displaced. Further studies are needed to evaluate the clinical significance of mild anterior displacement of the articular disk(11°-20°) in asymptomatic persons.
