The authors analysed 196 cases of convulsive disorder in children who were admitted to the pediatric department of Kyunghee Hospital from June 1993. Blood samples were drawn immediately following seizures on arrival. Serum prolactin values were measured by radioimmunoassay. The results obtained were as follows: 1) Mean serum prolactin value was 55.4+/-20.8ng/ml in generalized seizures within 1 hr following seizures, 22.5+/-3.9ng/ml in partial seizures. There was a significant difference between generalized scizures and partial scizures (p<0.05). 2) Mean serum prolactin value was 23.5+/-9.7ng/ml in generalized seizures within 1~3 hrs following seizures, 10.4+/-4.9ng/ml in partial seizures. There was a significant difference between generalized seizures and partial seizures (p<0.05). 3) Mean serum prolactin value was 9.5+/-4.4ng/ml in generalized seizures 3 hrs following seizures, 9.8+/-4.8ng/ml in partial seizures. There was no significant difference between generalized seizures and partial seizures (p>0.05). We found transient hyperprolactinemia following generalized seizures but a little change following gartial seizures. Postictal elevation of serum prolactin may represent a biochemical marker of generalized and partial seizures.

Objetcive To analyze the contrast-enhanced ultrasound (CEUS)features in clear cell renal cell carcinoma (CCRCC) of different size and to discuss the diagnostic value of CEUS in CCRCCs. Methods The contrast-enhanced and conventional US features of 80 CCRCCs confirmed pathologically were retrospectively analyzed. Samples were divided into three groups by diameters: small CCRCCs (≤30 mm), medium CCRCCs(>30 mm) and large CCRCCs(>50 mm). The tumoral vascularity, lesion homogeneity and presence of an anechoic rim were observed on conventional US. The enhancement of echogenicity, homogeneity and pseudocapsule were evaluated on CEUS. Results Among the 80 renal masses, 32 were small CCRCCs, 28 were medium CCRCCs while the large CCRCCs were 20. On conventional US, 18.8%(6/32) of small CCRCCs, 71.4%(20/28) of medium CCRCCs and 95%(19/20) of large CCRCCs demonstrated as heterogeneous and the differences were highly statistically significant, whereas there were no differences in the tumoral vascularity and the presence of pseudocapsule sign among the three groups. On CEUS, 28.1%(9/32) of small CCRCCs, 85.7%(24/28) of medium CCRCCs and 100%(20/20) of large CCRCCs showed a homogeneous enhancement. The incidence of pseudocapsule sign in medium tumors was higher than small and large groups(71.4%,50% and 25%,respectively). There were statistically significant differences among the three groups in the enhanced homogeneity and the presence of pseudocapsule sign. However, all the three groups revealed mainly isoechoic and hyperechoic and there were no differences among them. Compared with conventional US, CEUS depicted significantly the increased tumoral vascularity (51.3% vs. 87.5%) and pseudocapsule sign(22.5% vs. 51.3%). Eight lesions demonstrated heterogeneous contrast enhancement on CEUS while homogeneous on conventional US, but there were no differences in lesion homogeneity between conventional US and CEUS findings. Conclusions Different sizes of CCRCC showed distinct CEUS features in the enhanced homogeneity and the presence of pseudocapsule sign. CEUS is more effective on improving the sonographic characteristics of tumoral visualization and may provide important information of US findings for the diagnosis of renal cell carcinoma.

Objective To evaluate the effects of locking calcaneal plate in the treatment of SandersⅢ~Ⅳcalcaneal fractures.Methods 15 feet of 12 patients of SandersⅢ~Ⅳcalcaneal fractures received the treatment of internal fixation reduction with locking calcaneal plate and hone graft.Results All the patients were followed up for 4 to 21 months(average 11 months) with the results that according to Maryland foot score,4 feet were reported ex- cellent,6 good,1 average and 1 poor,with total excellent and good rate of 83.3 %.Conclusion Using locking cal- caneat plate in the treatment of complicated calcaneal fractures was proved to be a good method and had satisfactory effects.

Purpose: To investigate the extent of bone ingrowth into the porous-coated acetabular cups as well as the factors that correlated with bone ingrowth in total hip arthroplasty. Materials and Methods: Thirty six Harris-Galante porous-coated acetabular cups that were retrieved through revision surgery were examined in this study. Acetabular cups retrieved due to infection or severely destroyed cups (ed note: severe what?) were excluded. The extent of bone ingrowth into the acetabular cups was grossly measured, and its correlation with the variables including age, gender, weight, height, the duration of fixation, size, number of screws, inclination and anteversion was statistically analyzed. Results: The mean proportion of bone ingrowth was 52.9 21.9%(2~90%) and less than 30% in three cups(8.3%). The pattern and the location of bone ingrowth were not consistent. There was no correlation between the extent of bone ingrowth and age, gender, weight, height, the duration of fixation, cup size, number of screws, size, inclination and anteversion. Conclusion: Harris-Galante porous-coated acetabular cups showed satisfactory bone ingrowth regardless of the variables associated with the demographic or surgical conditions. Surface treatments with a fiber-metal porouscoating appears to be suitable for cementless acetabular cups in terms of the long term results.

OBJECTIVE: To estimate the burden of diseases in Korea especially caused by major cancers using the YLL(years of life lost due to premature death) measurement. METHODS: First, we determined the parameters: such as age-specific standard life expectancy, age on death, sex, cause of death by analyzing the national death certificate data and life table collected during 1996 provided by the National Statistical Office. Secondly, we estimated the age group-specific YLL by employing standard expected years of life lost(SEYLL). Thirdly, final burden of disease due to premature death was estimated by using YLLs measurement which developed by global burden of disease study group. RESULTS: The burden of premature death by cancer for male was attributed mainly to liver cancer(514.5 person-year), stomach cancer(436.4 person-year), and lung cancer(367.7 person-year). Each of these cancers was responsible for the loss of over 100 person-year based on our YLL measurement. The burden of premature death by cancer for female was attributed mainly to liver cancer(135.1 person-year), stomach cancer(252.1 person-year), and lung cancer(121.8 person-year). Each of these cancers was responsible for the loss of over 100 person year based on our YLL measurement. CONCLUSION: We found the YLL method employed in this study was appropriate to quantify the burden of premature death. Thereby, it would provide a rational bases to plan a national health policy regarding premature death caused by cancer.

We experienced a case of congenital goiter with congenital hypothyroidism in 45 day-old male, who complained of respiratory difficulty and anterior neck mass. After admission, he was diagnosed congenital hypothyroidism by the clinical manifestations and laboratory tests including biochemistry, radioimmunoassay, radioisotope study, perchlorate discharge test, and bone radiography. We obtained positive finding at the perchlorate discharge test and found that his congenital goiter with congenital hypothyroidism was manifested by organification defect. We started treatment with L-thyroxine orally at 6th hospital day. The case was presented with brief review of literatures.

We report a case of infantile digital fibromatosis in a 34 month-old boy, who presented with a painless subcutaneous tumor on the medial aspect of the left third toe. A histological examination showed scattered small, round eosinophilic inclusion bodies in the cytoplasm of the tumor cells, which was consistent with infantile digital fibromatosis. A'immunohistochemical study revealed that desmin, a-smooth muscle actin, and vimentin were clearly positive in the cytoplasm of the tumor cells, but the inclusions themselves showed negative staining, thus indicating a hollow-like staining pattern. Electron microscopy showed either well-defined or ill-demarcated dense bodies in the cytoplasm of the tumor cells. In some areas, small vesicles and intracellular organells were observed' in the inclusions. In the course of conservative treatment, a new lesion developed on the lateral aspect of the left third toe, seven months after the appearance of the initial lesion.
