Isoimmune hemolytic disease of the newborn due to anti-E is a disease characterized by the progressive neonatal hyperbilimbinemia and anemia which is caused by the IgG antibody transmitted from the mother to the ferns. Authors have experienced two cases of isoimmune hemolytic disease due to anti-E, who presented with jaundice on the first and the second day of life, respectively. The ABO and Rh blood types of their mother and father were B, CcDee and O, ccDEE, respectively. Both babies showed positive direct Coombs test and the mother showed strong positive indirect Coombs test. Antibody identification tests were made only in the first case and the mother, both of which revealed anti-E antibody. The first case was treated with phototherapy for 3 days and two blood transfusions. The second case was treated with phototherapy for 6 days and two exchange transfusions.

o evaluate the seroprevalence of viral hepatitis marker among Korean healthy voluntary blood donors, the positive rates of both serum HBsAg and anti-HCV were analyzed. HBsAg testing was performed in 9,561,768 donors from January 1986 to June 1994 and anti-HCV testing was performed in 4,407,933 donors from May 1991 to June 1994. Positive rates of HBsAg were 3.76% to 6.87% per year and anti-HCV were 0.37% to 0.58% per year. The sex distribution of positive HBsAg and anti-HCV showed higher in male that in female. The age distribution of positive HBsAg was higher in 3th decade and anti-HCV was in 5th decade. The positive prevalence rate of HBsAg and anti-HCV showed highter above the serum ALT 45 IU. The positive rate of HBsAg was higher in group voluntary donors and anti-HCV in various other type of voluntary blood donors. In generally, the positive prevalence rate of HBsAg and anti-HCV showing however decreasing number in every year.

PURPOSE: This study was performed to determine the incidence of BMM and to correlate the presence of these micrometastases with prognosis and othet clinicopathologic features. Materials AND Methods: BMM was evaluated in 220 breast cancer patients between July, 1991 and January, 1997, using mouse monoclonal antibody (AE1/AE3) against cytokeratin in an immunofluorescent assay. RESULTS: Of the 220 patients, 71 (32.3%) were positive for BMM. There were no association between bone marrow positivity and nodal status, TNM stage, known histopathologic parameters, and hormona1 receptor. Median follow-up for 220 patients was 41.6 month. The relapse rate was 16.8% (37/220). Twenty-four (33.8%) of 37 patients were positive for BMM and 13 (8.7%) were negative (p<0.05). Bone metastasis occurred in 16 cases, and was more common in BMM positive patients (14 of 24, 54.2%, versus 2 of 13, 15.4%, p < 0.05). Twenty-six patients were died of relapsed breast cancer. In overall survival, patients who was negative for BMM showed higher survival rate (p<0.05). CONCLUSION: BMM was a good predictor for distant metastasis, especially bone metastasis, and for poor prognosis. But no association was found between bone marrow positivity and tumor size, nodal status, stage, histologic parameter and hormonal receptor status.

PURPOSE: To evaluate the various phosphorus metabolism' of breast tumors with use of in vivo phosphorus-31 (31P) M R spectroscopy (MRS) MATERIALS AND METHODS: Five patients with breast tumor (benign in two, malignant in three) and three normal healthy volunteers participated in this study. All in vivo31P MRS examinations were performed on 1.5 Twhole-body MRI/MRS system by using a Free Induction Decay (FID) pulse sequence. Tl-weighted MR images were used for localization of tumors. Peak areas for each phosphorus metabolite were measured using a Marquart algorithm. RESULTS: Breast carcinoma had a substantially larger phosphomonoester (PME) and a smaller phosphocreatine (PCr) peak intensity than normal breast tissue. This was reflected in the relatively higher PME/PCr ratio of breast carcinomas as well as phosphodiester (PDE)/PCr, inorganic phosphate (Pi)/PCr, and adenosine triphosphate (ATP)/PCr ratios, compared with normal controls. The mean pH value of breast tumor demonstrating the alkaline nature was higher than that of normal controls. Spectral patterns between benign breast disease and normal breast tissue were quite similar, and differentiation was not established. CONCLUSION: Our preliminary study suggests that in vivo 31P MRS is a noninvasive examination which may be useful in the early differentiation of malignant breast tumors from normal and benign conditions. However, normal control and benign conditions could not be characterized on the basis of the phosphorus metabolite ratios.

OBJECTIVES: To investigate the hand-arm vibration syndrome (HAVS) among symptomatic swagging workers exposed to hand-arm vibration, using medical evaluation and measurement of workplace vibration. Furthermore, to evaluate the neurophysiological METHODS: Four workers showing symptoms relevant to HAVS were evaluated. Medical evaluation consisted of medical interview, questionnaire, nail-bed compression test, and sensory perception tests for vibration and pain. Some other diseases were excluded by a medical interview, hematological assessment, and urinalysis. Cold provocation test was used to assess the peripheral vascular changes, and a nerve conduction velocity (NCV) test was implemented to ascertain the peripheral neural changes. Pegboard, hole plate, and tapping board tests were performed to assess motor nerve function. The hand-arm vibration acceleration levels of the swagging machines were measured. Six months later, follow-up NCV tests were performed. RESULTS: The actual exposure time to vibration was not longer than 15 minutes per day. The hand-arm vibration acceleration levels of the swagging machines, according to actual exposure time, were from 3.63 to 12.98 m/sec2, by ISO 5349. The vibratory perception thresholds and the recovery time of a nail color following finger cooling were significantly increased in all four workers. The perception of pain was mildly increased. The nerve conduction studies at first diagnosis and follow-up showed multifocal neural impairment caused by vibration. However, we could not rule out the concomitant presence of the carpal tunnel syndrome in one worker. CONCLUSIONS: These results show that HAVS can be caused by hand-arm vibration in swagging workers. Interestingly, the NCV results suggested that vibration-induced neural conduction impairments could vary, and need to be interpreted cautiously.

PURPOSE: Intimal hyperplasia is an exaggerated proliferating response to arterial injury and can lead to occlusion and thromboses of arteries and bypass graft following arterial surgery or angioplasty. Medial smooth muscle cell activation has been implicated as the final common pathway leading to the development of intimal hyperplasia. Therefore, therapeutic agents that inhibit vascular smooth muscle cell proliferation should be selected to prevent restenosis. Recent laboratory data suggest that heparin and glucocorticosteroid have antiproliferative effects on smooth cells. We studied the effect of dexamethasone and low molecular weight heparin (LMWH: fragmin) on the suppression of intimal hyperplasia after balloon induced arterial injury in a rat model. METHOD: Twenty five rats were underwent aortic intimal denuation with 2F balloon catheter. The rats were divided into four groups: normal control group (sham operation), control group (experimental group without medication), dexamethasone treatment group (experimental group with intramuscular injection of dexamethasone) and fragmin treatment group (experimental group with subcutaneous injection of 60 IU/kg of LMWH (fragmin(R)). The dexamethasone treatment group was divided into 3 subgroups by graded doses of dexamethasone: subgroup 1, 2 and 3 were injected 0.05 mg/kg, 0.10 mg/kg and 0.15 mg/kg of dexamethasone respectively. Injection of drugs were started 1 days before the intimal injury and continued for 4 weeks, dexamethasone were injected six times a week and fragmin injected daily. The aorta were harvested at 6 weeks after injury. Microscopic examination and cross sectional intima to media height ratio (IMHR) were evaluated. RESULT: All treatment groups showed significant suppression of intimal hyperplasia compare to the control group (P<0.05). Mean IMHR were 0.69+/-0.15 in the control group, 0.39+/-0.11, 0.31+/-0.15 and 0.29+/-0.09 in dexamethasone treatment subgroup 1, 2 and 3 respectively, and 0.39+/-0.14 in fragmin treatment group. There were no statistical difference in dexamethasone treatment subgroups. CONCLUSION: Dexamethasone and LMWH were effective in suppression of the intimal hyperplasia to an intimal injury in a rat model. In addition, the minimal effective dose of dexamethasone that required to achieve the suppression of intimal hyperplasia is 0.05 mg/kg in this study.

To evaluate the role of internal jugular node sampling in the operation for well-differentiated thyroid cancer, 86 patients received the operation for well-differentiated thyroid cancer from one surgeon. Ipsilateral internal jugular node (level 3 and 4) sampling was done after total thyroidectomy and central compartment neck dissection (CCND) in clinically node negative well-differentiated thyroid cancer. A modified radical neck dissection, type IIIB, was done in the patients proved as metastasis on the frozen biopsy of the sampling. The overall metastatic rate of the internal jugular lymph node was 72.5% (50 of 69), and the metastatic rate of the internal jugular node sampling in clinically negative lymph node metastasis was 57.4% (31 of 54). The most frequent metastatic lymph-node group was level 6. The metastasis of the internal jugular lymph node was more frequent in large tumor and extracapsular involvement, but there was no statistical significance. The rates of internal jugular node metastasis were 50.0% in follicular, medullary, and H rthle cell carcinomas. In conclusion, sampling of the internal jugular node was an important guideline in deciding a modified radical neck dissection in patients with well-differentiated thyroid cancer.

Acromegaly and hyperprolactinemia have been described in association with polyostotic fibrous dysplasia. The pathogenic mechanisms of this endocrinopathy are not clear. We experienced a 19-year-old male with hypersecretion of GH, hyperprolactinemia and fibrous dysplasia. He was referred for evaluation of suspected acromegaly. He had no skin pigmentation. Plasma GH, PRL, somatomedin-C, LH, FSH, testosterone, estradiol, progesterone, T3, T4, TSH and cortisol were measured. Among those, the levels of plasma GH, PRL and somatomedin-C were high. Serum alkaline phosphatase was increased. OGTT did not suppress plasma OH concentration and GH showed paradoxical response to TRH and LHRH. GH was suppressed after a test-dose of somatastatin and bromocriptine. Brain MRI demonstrated a mass lesion in sella turcica and another mass lesions in nasal cavity and posterior occipital bone. Whole body bone scan revealed increased uptake in skull, nasal bone, both 9th posterior rib, both femurs, both tibias, left scapular and pelvic bone. These fmdings were consistent with bone tumor such as fibrous dysplasia. We report a case with incomplete MeCune-Albright syndrome including acromegaly, hyperprolactinemia and polyostotic fibrous dysplasia.
