PURPOSE: To evaluate abnormal neurosonographic (NSG) findings of thalami and basal ganglia in full term babies with hypoxic-ischemic encephalopathy and to correlate the findings with follow-up studies and prognosis. METHODS: We evaluated 13 full term babies with abnormal NSG findings of thalarni and basal ganglia. NSG was performed within 7 days after clinical abnormalities. Follow-up NSG was done in 11 cases; CT scan in 4 and MRI in 7. We classified NSG findings as diffuse, unilateral, and focal types according to increased echogenicity and evaluated prognosis based on follow-up studies and neurological sequelae. RESULTS: Nine cases of diffuse type had diffuse echogenic changes of bilateral thalami and basal ganglia, slit-like lateral ventricles suggesting cerebral edema, and increased parenchymal echogenicity. In diffuse type, follow-up studies showed more prominent echogencities and ventricular dilatations and cerebromalacia. One case of unilateral type caused by thromboembolism had unilateral echogenicity of right thalamus and basal ganglia with increased echogenicity of the ipsilateral cerebral hemisphere and compression of the lateral ventricle, suggesting cerebral infarction. Follow-up study showed unilateral cystic cerebromalacia. Three cases of focal type had a localized echogenic area in thalamus with lacunar infarction, which decreased in size during follow-up. Among nine cases of diffuse type, one died within 2 days, two were discharged against medical advice, and six had severe neurologic sequelae. One case of unilateral type had a moderate degree of neurologic sequelae. All 3 cases of focal type had normal development. CONCLUSION: Pattems of abnormal echogenicity in thalami and basal ganglia in fullterm infants with hypoxic-ischemic encephalopathy are correlated with the outcome and may be helpful for treatment planning.

The Peutz-Jeghers syndrome is a familial disesse charaeterized by mucocutaneaus pigmentation, gastrointestinal polyposis, and transmission of autosomal dominant trait. This syndrome is clinically important becuase of the coreplieation caused by the polyp, leading to abdominal pain, gastrointestinal bleeding, and intussusception. Authors experienced a case of Peutz-Jeghers syndrome admitted to Walace Memorial Baptist Hospital who was complained of recurrent abdominal pain, melanin pigmentation of lips, oral mucosa, and digits. UGI series, small bowel series, colon cnema, gastrofiberscopy, and colonoseopy revealed multiyle intestinal polyps. Pathologic findings on endoseopic polypectomy showed hamartomatous polyp.

We studied anti-HBs titer, positive and effective rate in relation to dosages(5microgram, 10microgram) and time interval after third vaccination in 23 infants born to HBsAg negative mother. The babies were divided into two groups. In one group(n=12), 5microgram of Hepavax was administered intramusculary at 1 month, 2 months and 6 months of age, in other group (n=11), 10microgram of Hepavax at same time interval. And the anti-HBs was studied at 2 months and 3 year after third vaccination by radioimmunoassay. The results were as follows: 1) The anti-HBs positive rate was 100% in two groups at 2 months and 3 years after vaccination. 2) The geometric mean anti-HBs titer at 2 months after third vacciantion was 9418.3+/-13041.5 IU/L in 5microgram group and 12750.0+/-12750.5 IU/L in 10microgram group, and 3 year after vaccination, 949.4+/-1404.0 IU/L in 5microgram group, 1067.4+/-1067.7 IU/L in 10microgram group. There were no significant difference between two groups, although mean anti-HBs titer decreased significantly after 3 years. 3) The effective rate at 3 years after vaccination was 66.7% in 5 microgram group and 72.8% in 10microgram group. There was no statistical significant difference between two groups.

PURPOSE: To compare the detectability and conspicuity of focal hepatic lesions among conventional spin echo techniqueniques and fast scanning techniqueniques in MR imaging. MATERIALS AND METHOD: 36 patients (24 men and 12 women, mean age of 54 years) with suspected liver mass on CT scan and US underwent MR imaging at 1.5 T system. Conventional spin echo T1, T2 weighted imaging, T2 weighted fast spin echo, T1 weighted fast multiplanar spoiled gradient recalled(FMPSPGR) imaging and Gd-enhanced FMPSPGR(Gd-FMPSPGR) were performed. 16 cases of hepatocellular carcinoma, 13 cases of hemangioma, 3 cases of metastasis, 3 cases of cholangiocarcinoma, and 1 case of lymphoma were included. Lesion conspicuity and number of detected hepatic masses were compared among the MR sequences. RESULTS: Overall 63 hepatic lesions were detected in 36 patients. Lesion detection' was 63(100%) with Gd-FMPSPGR, 62(98%) with non-enhanced FMPSPGR, 58(92%) with SE T2WI, 56(89%) with SE T1WI and 54 (86%)with FSE. For solid tumors, the contrast to noise ratio was greatest on Gd-FMPSPGR which was significantly higher than any other sequences. For hemangiomas it was greatest on SE T2WI and was significantly higher than SE T1WI. In the qualitative assessment, Gd-FMPSPGR was preferred for both solid mass lesion and hemangioma. FSE was inferior to SE T2WI for lesion detection and conspicuity without statistical significance. CONCLUSIONS: For the evaluation of focal hepatic lesions, breath-hold FMPSPGR with and without contrast enhancement may replace the conventional SE T1WI. Because FSE was inferior to SE T2WI when the later is used with respiratory compensation in some cases, it is difficult to replace the SE T2WI with FSE. But FSE, FMPSPGR and Gd-FMPSPGR images, when combined, may replace SE T1WI and SE T2WI.
