Hyperinsulinemic hypoglycemia is a relatively rare disease in childhood period except neonate, but hypoglycemia due to delicate imbalance between glucose production & consumption is evoked easily and left permanent damage to brain at these period. The definition is that serum insulin level is above 10microU/ml when blood sugar level is below the 40mg/dl and so I/G ratio is higher than 0.4. The clinical manifestations are irrtability, frequent feeding and seizures etc. and there is no specific pancreatic pathology in most cases. We experienced 2 cases of hyperinsulinemic hypoglycemia with pancreatic hyperplasia and pancreatic adenoma each other. The diagnosis was made on clinical manifestations, laboratory results, radiologic and pathologic findings. We reported these cases with brief review of literature.

To assess the effectiveness of Magnetic Resonance Imaging (MRI) with endorectal surface coil in the ataging of carcinoma of the uterine cervix with emphasis on parametrial involvement. Thirty women with clinically and radiographically proven carcinoma of the uterine cervix were initially included for this study, but thirteen patients were excluded since the stages of tumors wore beyond stage IIa. CT and MR findings of the remaining seventeen patients were performed at Cheil General Hospital and compared a1ong with clinical findings with the special emphasis on the parametrial involvement by the tumor. Staging was assessed by CT and MRI, and the results were compared with the pathologic staging. Radiea1 abdominal hysterectomy with the pelvic and paraaortic lymphnode dissection was done to all sewenteen patients. The staging made primarily by CT and MRI was either stsge 1 or Ila, but MR images with endorectal surface coil was superior to CT in the visualization of depth of tumor infiltration, especially parametrial involvement. The determination of the depth of the tumor made by MR images showed statistically significant correlation with histologic evaluation(R =0.768, p<0.01). The accuracy rate for the evaluation of the parametrial invo1vement was 82.3% far CT and 94.1% for MRI with endorectal surface coil. The overall accuracy rate for tumor staging was 70.5% for clinical, 58.8% for CT and 82.3% for MR evaluation. The accurecy rate in evaluation of the pelvic and paraaortic lymphnode was 88.2% for CT, but the evaluation done by MRl was not adequate due to small FOV(field of view). In assessment of The steging of careinoma of the uterine cervlx, MR images with endorectal surface coil was superior to CT, especially in the evaluation of the parametrial involvement.

A new intravenous anesthetic agent, propofol reduces arterial blool pressure and reduces cardiovascular changes of tracheal intubation. The purpose of this study is to evaluate the effects of administration of thiopental 5 mg/kg and propofol 2.5 mg/kg on cardiovascular changes of tracheal intubation. Systolic arterial presure, diastolic arterial pressure, mean arterial pressure, heart rate and rate-pressure product were determined in healthy patients seheduled for tracehal intubation for general anesthesia before induction, after induction, 1, 3, and 5 minute after tracheal intubation. 1) After induction of anesthesia, above cardiovascular measurements except heart rate decreased significantly in both groups, but more profoundly in the propofol group. Heart rate did not change significantly in both groups. 2) Systolic arterial pressure, diastolic arterial pressure and mean arterial pressure increased significantly in the thiopental group after tracheal intubation, but decreased significantly in the thiopental group after tracehal intubation, but decreased significantly in the propofol group. After tracheal intubation, heart rate and rate-pressure product increased significantly in both groups, but the propofol group returned to the control value faster than the thiopental groups. In conclusion, in healthy adult patients, rise in the arterial blood pressure and heart rate after tracheal intubation decreased significantly in the propofol group compared with the thiopental group.

PURPOSE: To evaluate high-resolution CT(HRCT) findings of the miliary tuberculosis and their significancy. MATERIAL AND METHOD: We retrospectively studied clinical records, HRCT and chest radiographs of 14 patients with miliary tuberculosis. RESULTS: On HRCT, nodules were seen in all 14 cases, 10 of them evenly, and 4 were irregularly distributed. The size of each nodule was less than 1 mm in 7 cases, 1 --2ram in 6 cases, and 3mm or more in 1 case. The ground - glass opacity was accompanied in 8 cases, and fine reticular opacity was also noted in 8 cases. Other associated findings were pleural effusion (n=4), hilar and mediastinal lymphadenopathy (n=3), consolidation of the exudative tuberculosis (n=4). CONCLUSION: HRCT findings of miliary tuberculosis are diffusely distributed micronodules of variable size, less than 5mm in diameter. The ground-glass opacity can be combined.

We experienced a case of anterior mediastinal teratoma in 26 month old boy with 2 month history of cough and dyspnea. The diagnosis was easily established by chest CAT which revealed calcific densities, while plane radiographs of chest revealed no evidence of calcification. Operation was done with good result and remained in good condition thereafter. A brief review of the related literature was made on this subject.

The nm23 gene was originally identified by differential screening of a cDNA library with RNA from low and high metastatic clones of a murine melanoma cell line. And the nm23 gene has been represented as a metastasis suppressor gene. The product of nm23 gene is known to be identical to nucleoside diphosphate(NDP) kinase. The lack of expression of nm23 protein has been correlated with a poorer prognosis in some human tumors, among which are breast carcinoma, malignant melanoma, gastric carcinoma and hepatcelluar cacin-oma. However, in several types of malignant tumors such as colon carcinoma, neuroblastoma and pancreatic carcinoma, unexpected overexpression of nm23 protein was found as compared with normal tissues. Also in a few studies with cervical carcinoma, the expression of nm23 protein was found to be increased as compared with normal cervical tissue recently. Therefore, in this study, we analyzed the expression of nm23-H1 protein by immunohistochemistry method in a series of 40 cervical carcinomas, to determine whether the alterations in the expression of nm23-H1 protein occured in cervical carcinoma as compared with cervical intraepithelial neoplasia(CIN) and normal cervices, and also analyzed the possible association between nm23 protein expression and prognostic parameters of cervical carcinoma at Ewha Womans University Mokdong Hospital from September 1993 to March 1997. The results obtained were as follows; 1. The mean ages of normal control patients, CIN and cervical carcinomas were 42.9 (+/-5.1) years, 39.5(+/-7.7) years, and 49.3(+/-11.7) years respectively. All cases of cervical carcinoma were squamous cell carcinomas. And the number of each stages Ia, Ib, IIa, IIb, III and IV were 13 cases, 8 cases, 6 cases, 9 cases, 2 cases, and 2 cases respectively. 2. In cervical carcinoma, nm23-H1 protein expression was significantly increased as compared with CIN and normal cervical tissue(t=5.017>1.96). 3. In cervical carcinoma, the nm23-H1 protein expression was more increased in higher stages(p=0.021). But it had no significant correlations with primary tumor size, lymphovascular space invasion, parametrial invasion or lymph node metastasis. Our results on nm23-H1 protein expression in cervical carcinoma suggest that cervical carcinoma seems to belong to the group of tumors, like colon carcinoma and neuroblastoma, pancreatic carcinoma in which nm23-H1 overexpression is associated with a more malignant phenotype. In this study, nm23-H1 protein was more expressed in higher clinical stages of cervical carcinoma. Therefore the expression of nm23-H1 protein probably may have a prognostic significance in cervical carcinoma. But a further prospective study on a larger population is needed to establish the role of nm23 gene in this kind of tumor.
