Background: Cerebral palsy is due to static encephalopathy during perinatal period. Selective dorsal rhizotomy (SDR) involves selective division of posterior nerve roots to reduce spasticity and improve function in children with spastic cerebral palsy. Anesthesia during SDR must preserve muscle contraction in response to direct electrical stimulation of the dorsal nerve roots. We did this study to get the better management of anesthesia for SDR. Methods: Anesthetic records were reviewed for 16 patients who underwent SDR during January 1996 to August 1997. Demographic data; anesthetic drugs and doses; changes of vital signs and end tidal CO2; dorsal root stimulation; postoperative pain control were analysed. Results: The mean age of patients was 4.9+/-1.7 years old. The mean weight was 16.3+/-4.0 kg. The under 1 MAC concentration of isoflurane and 2~3 mcg/kg/hr fentanyl did not interfere with electrophysiologic monitoring. Esophageal temperature was increased significantly during electrical stimulation of dorsal roots. End tidal CO2 concentration had a tendency to increase after electrical stimulation too. Direct installation of 10~15 mcg/kg intrathecal morphine prior to dural closure, and postoperative 0.5 mcg/kg/hr fentanyl had a good postoperative analgesia without complication. Conclusions: Isoflurane and fentanyl during anesthesia, and intrathecal morphine with continuous infusion of fentany postoperatively are suggested a good anesthetic method for SDR.

PURPOSE: We performed this study to compare T1-201 and Tc-99m MIBI scans for the differentiation of malignant from benign breast mass. MATERIALS AND METHODS: Thirty-eight female patients underwent T1-201 breast scan and thirty-two of them also underwent Tc-99m MIBI scan of the breast. After intravenous injection of 74-111 MBq of T1-201, early (10 minutes) and delayed (3 hours) images were obtained. Then, 555-740 MBq of Tc-99m MIBI was injected and images after 30 minutes were obtained. We compared T1-201 and Tc-99m MIBI scans with pathologic RESULTS. RESULTS: Twenty-three patients were confirmed to have infiltrating duct carcinoma and fifteen patients to have benign breast mass by excisonal biopsy. The sensitivity of early and delayed T1-201 scan and Tc-99m MIBI scan in the detection of malignant breast lesion were 100% (23/23), 82% (18/22), and 90% (18/20), respectively. The specificity of early T1-201 scan was significantly higher than that of delayed T1-201 scan (p<0.05). The specificity of early and delayed T1-201 scan and Tc-99m MIBI scan were 73% (11/15), 73% (11/15) and 83% (10/12), respectively (p:not significant). Three patients out of nine with fibroadenoma and one patient with atypical duct hyperplasia were false positive in both early and delayed T1-201 scans. The size of fibroadenoma with false positvie in early and delayed T1-201 scan (4 cases) was larger than that of 11 fibradenoma with true negative scan (p<0.01). Metastatic axillary lymph node involvement was present in fifteen patients. The sensitive to detect metastatic nodes was 38% (5/13) for early T1-201 images, 15% (2/13) for delayed T1-201 images, 58% (7/12) for Tc-99m MIBI planar images and 67% (4/6) for Tc-99m MIBI SPECT. The sensitive of Tc-99m MIBI planar or SPECT was significantly higher than that of delayed T1-201 images (p<0.05). CONCLUSION: Early T1-201 and Tc-99m MIBI scan are useful noninvasive methods to differentiate malignant form benign mass of breast. Tc-99m MIBI scan was sensitive in detecting axillary lymph node metastasis in patients with brease cancer.

The incidence of tinea capitis was the least in the middle of 1970s, and thereafter it has been msrkedly increased along with other superficial mycoses due to Microsporum cania This study was to investigate the recent clinical and mycological trends of tinea capitis among the individuals of both out-patients of dermatologic clinic and orphanage children. These study data were compiled from 47 out-patients, which consisted of 31 patients from St. Pauls Hospital from September, 1980 to August, 1981 and 16 from St. Marys Hospital and Kangnam St. Marys Hospital from February to May in 1981, and from 79 patients of the orphage located in Seoul area in May, 1981. The results were as follows: 1. M. canis was isolated from all 47 out-patients with tinea capitis(male: 21, female 26). In orphanage, from 50 patients(63.3%) among the 79 patients with tinea capitis, 46 strains(92%) of T. ferrugineum from 30 male and 16 female patients, 3(6%) of M. canis from 3 males, and 1(2%) of T. violaceurn from a female were isolated. 2. The incidence of tinea capitis by M. canis in a total 5, 340 out-patients was 0. 58% (0. 62% in male, 0.56% in female) and its monthly distribution was almoat even through the studied period. The male to female ratio was 1:1,24, being more prevalent in female. 3. The age of onset was younger in female with tinea capitis due to M. canis than in male: The median age of onaet was 5 years in female and 7 years in male. In the group below 7 years of age, the maIe to female ratio was 1:1.84 and in the group above 8 years of age, l.74: 1.4. Most lesions of tinea capitis due to M. canis from out-patients showed multiple round grey scaled patches with shrotened hairs or round erythematous scaled alopetic patches. Kerion celsi were found in 4(9%) out of 47 out-patiente. Tinea corporia was combined in 4(9%) out-patients. There were domestic animals shch as kit or dog in 7(29%) among 24 houses of the patients.

BACKGROUND: Management of massive rotator cuff tears can be challenging because of the less satisfactory results and a higher retear rate regardless of the use of open or arthroscopic repair technique. METHODS: We retrospectively analyzed 102 cases of massive rotator cuff tear treated with either open or arthroscopic repair. Open repair was performed in 38 patients; and arthroscopic repair, in 64 patients. The mean age at the time of surgery was 59.7 years in the open group and 57.6 years in the arthroscopic group. RESULTS: The Constant score increased from the preoperative mean of 55.9 to 73.2 at the last follow-up in the open repair group and from 53.8 to 67.6 in the arthroscopic repair group (p<0.001 and <0.001, respectively). The University of California at Los Angeles (UCLA) score increased from a preoperative mean of 17.7 to 30.8 at the last follow-up in the open group and from 17.5 to 28.7 in the arthroscopic group (p<0.001 and <0.001, respectively). No statistically significant difference in the Constant and UCLA scores was observed between the two groups at the last follow-up (p=0.128 and 0.087, respectively). Retear was found in 14 patients (36.8%) in the open group and 39 patients (60.9%) in the arthroscopic group (p=0.024). CONCLUSIONS: Open and arthroscopic repairs of massive rotator cuff tears may provide satisfactory clinical results with no significant difference. However, a significantly lower retear rate was observed for the open repair group compared with the arthroscopic repair group.

Urticaria pigmentosa developed in twins at the age of 6 weeks. They have numerous round to oval shaped, discrete or confluent reddish brown colored macules over whole body surface and neither twin had vomiting, diarrhea, flushing or irritability. Their relatives are unaffected. Biopsy specimen of. back lesion showed. pooling of mast cells in the upper dermis, and electron microscopic examinattion revealed normal mast cells.

In order to evaluate the genotoxic hazard among workers potentially exposed to low level petrochemical substances, the analyses of micronuclei (MN) and sister chromatid exchanges (SCEs) in lymphocytes were performed in 46 male workers (as exposed group) and 46 nonexposed subjects (as control group). Mean frequencies of MN and SCEs (respectively, 12.9/1000 cells and 6.5/cell) in exposed group were very significantly higher than those (10.2/1000 cells and 5.4/cell) in control group. And there were also significant differences in mean frequencies of MN and SCEs adjusted for age, employment duration, smoking, and drinking between two groups. Median frequencies of MN and SCEs in exposed group were very significantly higher than those in control group. Frequencies of SCEs were higher in smokers than in non-smoker. Frequencies of MN in smokers, however, were similiar to those of non-smoker. Interaction between exposure and smoking on MN and SCEs induction was not observed. The results suggest that there is genotoxic hazard in high risk group like workers handling carcinogens in petrochemical plants and the analyses of MN and SCEs are useful biomarkers for the exposure to hazard substances even at the level below the exposure limit.
