Immunohistochemical staining on paraffin sections for S-100 protein improved diagnostic accuracy for melanocytic tumor. But specificity of S-100 protein in the diagnosis of melanocytic tumor is very low, because S-100 protein was also expressed in neurogenic tumor and salivary gland tumor. To investigate a specific tumor marker for the malignant melanoma, immunohistochemical staining for HMB-45 and S-100 protein was performed on the paraffin sections of 25 cases of malignant melanoma and 46 cases of nevi. Positive reaction for HMB-45 and S-100 protein was diffusely identified in the cytoplasm of tumor cells. Positive ratio for HMB-45 was 100% in malignant melanoma, 92% in junctional component of compound nevus and 0% in intradermal nevus. Positive ratio for S-100 protein was 92% in malignant melanoma, 100% in compound nevus and 100% in intradermal nevus. The sensitivity and specificity for HMB-45 in malignant melanoma were 100%, but those for S-100 protein were 92% in sensitivity and 86.7% in specificity. These results indicate that HMB-45 has a high sensitivity and specificity for malignant melanoma cells and it can be quite useful for the histopathological diagnosis of malignant melanoma.

BACKGROUND: Obesity is linked to a wide range of respiratory diseases. Several studies have shown that body weight at baseline and weight change were related to pulmonary function. The purpose of this study was to investigate the relationship between change in body mass index (BMI) and pulmonary function in adults. METHODS: Of those aged 40-64 years at baseline who had initially visited the health promotion center at one university-level hospital from January 2000 to December 2002, 499 (men: 309, women: 190) patients revisited the center over a 5-year period up to December 2009 and were enrolled in the study. Subjects were classified into 4 groups- group 1: normal-normal, group 2: normal-obese, group 3: obese-normal, and group 4: obese-obese, based on their BMI at baseline and follow-up. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and FEV1/FVC were measured by spirometry. RESULTS: Change in FEV1/FVC was significantly associated with change in BMI for men in all 4 groups. Change in FEV1/FVC was significantly different between group 1 and 3 and between group 1 and 4. Changes in FEV1, FVC and FEV1/FVC were significantly associated with change in BMI for women in all 4 groups. Change in FEV1 was significantly different between group 3 and 4, and change in FVC was significantly different between group 1 and 3. CONCLUSIONS: These results suggest that a change in BMI is negatively associated with change in pulmonary function. Obesity itself can be a risk factor for pulmonary dysfunction, and a decrease in BMI through weight reduction could reduce pulmonary dysfunction or improve pulmonary function in adults.

The author has studied on the differences in blood pictures, especially the differences of blood pictures in capillary blood and venous blood, in 25 premature babies and 50 term babies from birth to 7 days of age sequentially during the period of 6 monts from April 1980 to Sept. 1980. The results are summarized as follws; 1. As comparing blood pictures with term babies, premature babies showed somewhat lower values in erythrocyte, hemoglobin, hematocrit. MCV, MCH, leucocyte and platelet but somewhat higher values in reticulocyte and MCHC. 2. As comparing blood pictures with the venous blood, the capillary blood showed significantly higher values in erythrocyte, hemoglobin and hematocrit during the neonatal period in both premature babies and term babies, but showed somewhat lower values in MCV, MCH, MCHC, and platelet. 3. According to the time of clamping the umbilical cord after birth, there were significant differences of blood pictures between early and late clamping of the umbilical cord. 4. The highest mean erythrocyte counts in both term babies and premaature babies were 5,896,000/cub.mm and 5,542,000/cub.mm at 3-6 hours after birth. Those values were gradually decreased to 5,104,000/cub.mm and 4,753,000/cub.mm on the 6th-7the day of life. 5. The highest average hemoglobin levels in both term babies and premature babies were 21.1gm/dl and 19.5gm/dl at 3-6 hours after birth. Those values were gradually decreased to 18.1gm/dl and 17.1gm/dl on the 6th-7th day of life. 6. The mean values of hematocrit in both term babies and premature babies were higest, 64.5% and 59.9% at 3-6 hours after birth. Those values were gradually decreased to 54.8% and 50.2% on the 6th-7the of life. 7. The average total serum protein levels in both term babies and premature babies were 5.76gm/dl and 5.22gm/dl at birth. Those values were increased to 6.45gm/dl and 5.74gm/dl at 3- hours after birth. 8. The average MCV in both term babies and premature babies showed highest values, 114.2fl and 110.1fl at birth. Those values were gradually decreased to 107.0fl and 103.4fl on the 6th-7th day of life. 9. The average MCH in both term babies and premature babies showed highest values, 36.8pg and 35.3pg at birth. Those values were gradually decreased to 107.0fl and 103.4fl on the 6th-7th day of life. 10. The average MCHC in both term babies and premature babies showed constant levels, 31.3-32.0% and 32.2-33.1% from birth to 7the day of life. 11. The average platelet counts in both term babies and premature babies were 243,000/cub.mm and 229,000/cub.mm during the first 4 days of life. Those values were gradually increased to 283,000/cub.mm and 253,000/cub.mm on the 6th-7the day of life. 12. The highest reticulocyte counts in both term babies and premature babies were 3.1% and 3.6% at the age of 3-6 hours. Those values were rapidly dropped down from 4th day to 7th day of life, decreasing from 1.7% and 1.9% to 1.0% and 1.3%. 13. The highest llecucyte counts in both term babies and premature babies were 25,794/cub.mm and 23,363/cub.mm at the age of 3-6 hours. Both values were gradually decreased to 13,213/cub.mm and 11,870/cub.mm on the 6th-7th day of life.

Rett syndrome is progressive neurodegenerative disorder in female patients, characterized by autistic behavior, mental retardation, loss of purposeful hand skills, stereotypic hand movement, breathing dysfunction, severely impaired language, ataxia, and seizure. The diagnosis of Rett syndrome is based on its characteristic clinical manifestation and course. The electroencephalographic (EEG) findings of Rett syndrome are nonspecific, but a progressive deterioration in the EEG, characterized by a slowing of background activity and spike sharp wave discharges, may be observed. We experienced one case of Rett syndrome in a 5 year old girl having mental retardation, loss of purposeful hand skills, stereotypic hand movements (clapping, washing, hand-to-mouth), breathing dysfunction (hyperventilation/apnea). Her EEG findings on Video-EEG monitoring are excessive slowing waves during awake state and frequent spike discharges from left or centrotemporal area during sleeping. We report a case of Rett syndrome with brief review of related literatures.
