The serum level of immunoglobulin E (IgE) in 28 atopic patients and 41 healthy, normal, non-allergic subjects were measured by standard radial immunodiffusion method (RIDT). The correlation between IgE level and clinical manifestations are studied. The results are as follows. 1) IgE value was higher in atopic dermatitis than normal subjects. 2) IgE value in atopie dermatitis revealed no sigaificant difference between in male and in female. 3) IgE value was increased parallel with the severity of the disease. 4) IgE value was not correlated with the extent of disease. 5) IgE value was not correlated with the duration of disease. 6) IgE value was not correlated with the age of onset. 7) IgE value was not correlated with the eosinophil count of peripheral blood.

Melanoma is relatvely uncommon malignant tumor arising in the skin from epidermal melanocytes, from the junctional component of a cellular nevus or, rarely within a blue nevus and frequently metastasizes to regional lymph nodes first, followed by hematogenous spread to lungs, liver, gastrointestinal tract, pancreas, adrenal, heart and brain. All melanoma patients are carefully evaluated according to several parameters. A complete history and physical examination are carried out, with particular attention being devoted to other pigmented tumors that the patient may have. The patient should be further evaluated to determine the presence or absence of metastases by chest X-ray examination, metastatic series or bone scan, liver function studies, liver scan, EKG, etc. Special factors such as age, sex, and race, as well as site, size, and growth rate of lesions are also evaluated. We had a case of 59 year-old male patient with disseminated malignant melanoma. Upon his first visit, we did not find any abnormality in his physical examination and routine laboratory findings except skin tumors on left heel and left leg.

Vertebral pedicle screws have been widely used for secure posterior spinal fixation. When postoperative CT scan films were made, the blurring of pedicle screws were observed and we could not figure nut the exact diameter of screw and canal encroachment. There is no information in the difference hetween actual diameter and measured diameter of pedcile screws in CT yet. In this study, we try to find out partial voiume averaging artifact of pedicle screws made of stainless steel and titanium. Partial volume averaging artifact occurs when the shape of an object changes within the thickness of the CT slice or when a relatively small object is only partially included within the slice. Four pig cadaveric spinal column including 6 vertebrae each were prepared and CT scans were performed after insertion of C-D screws(stainless steel) to the left and TSRH screws(titanium) to the right pedicle. Another CT scans were performed after insertion of C-D screws to the right and TSRH screws to the left pedicle. The third CT scans were made after removal of all the pedicle screws. Actual C-D screw diameter was 6mm and CT scanned diameter was 8. I 6+/-0.66mm. Actual TSRH diameter was 6.5 mm and CT scanned diameter was 6.59+/-0.34mm. In conclusion, stainless steel has more partial volume averaging artifact than titanium. Safety margin of pedicle screw made of stainless steel is about 2mm and that of titanium is about 1 mm.

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.

PURPOSE: Neuroendocrine (NE) cells of the prostate are considered to be involved in the pathogenesis of benign prostate hyperplasia (BPH). By a comparative analysis of NE cell density in BPH tissue of men who were either exposed to or not exposed to 5alpha-reductase inhibitor, we investigated the relationship between NE cells and BPH, and the effect of androgen deprivation on NE cells. MATERIALS AND METHODS: Prostate tissue specimens, obtained from 30 men by transurethral resection of the prostate or radical cystoprostatectomy, were used. Of the 30 patients, 10 had a prostate smaller than 25 ml (normal control), the other 20 had a prostate larger than 40ml, 10 of who had taken 5alpha-reductase inhibitor (finasteride) for 3 months before surgery (androgen blockade group), and 10 who had not (BPH group). The distribution of NE cells in the prostate was examined using the anti-chromogranin A (CgA) antibody, and the density of the CgA-positive cells was compared by an optical dissector method. Immunoblotting was performed using the neuron specific enolase (NSE) antibody. A Mann-Whitney U test was used in a statistical analysis. RESULTS: Most of the CgA-positive NE cells were localized between the acinar epithelial cells. The mean numbers of CgA-positive NE cells per acinus in the normal controls and the BPH groups were 1.67+/-0.78 and 4.45+/-2.54, respectively, and the difference was statistically significant (p<0.05). However, the mean number of CgA-positive NE cells in the androgen blockade group, was 4.93+/-2.17, which was similar to the BPH group. In a NSE immunoblotting study, a distinct band was observed in the BPH and androgen blockade groups, but the density of the band was higher in the androgen blockade group. CONCLUSIONS: Our results suggest that NE cells may be involved in the hyperplastic process of BPH. Inhibition of dihydrotestosterone, caused by the oral administration of the 5alpha-reductase inhibitor, failed to induce any significant change in the NE cells, probably due to the incomplete androgen blockade.
