A 12-year-old boy showed a slatecolored scaly patch on h; ight face for 2 months. Histopathologic findings showed basal vacuolations and dermal me arphages with only scanty lymphoid cells in the fat tissue layer. Besides the facial lesion, lesions of edematous localized erythema were noted on his right if and left buttock with similar mi rocopical findings. 6 months later the facial lesion was aggravated like a cellulitis, of which thc bevpsy findings were consistent with mycosis fungoides. The patient received chemotherapy aftei the diagonsis for one month before his termination. Because of the rarity of mycosis fungoides in childhood age and its un common cutaneous lesions, the case is reported.

BACKGROUND AND OBJECTIVES: The change of voice quality on menstrual cycle is regarded as general in professionals. The primary objective of this study is to evaluate the changes of acoustic parameters during menstrual cycle in general population. METHODS: Twenty young adults were asked to produce vowel /a/, /i/ , and /u/ and to read book audibly at the proliferative phase of the menstrual cycle and premenstrual phase. And then, the sound of the voice in each case was recorded and analyzed by the Computerized Speech Lab. (CSL, Kay Elemetrics, Model 4300B, USA). The statistical analyses were performed using paired t-test to compare several variables of data. RESULTS: Compared with the acoustic parameters between two periods, there were no significant differences in all subjects. But the acoustic parameters with book-reading loudly during menstrual cycles revealed slight changes in voice quality. CONCLUSION: The change of voice quality, especially the fatigue of voice may be concerned with menstrual cycle, so more careful voice habituation was required during the menstrual period.

BACKGROUND: Although blood is very important therapeutic agent in bleeding patients, it may transmit disease, cause an adverse reaction in the recipients, raise the cost of patient care. Since the misuse and inappropriate use of blood is common, we are to review the transfusion practice in our hospital and to reduce unnecessary blood transfusion. METHODS: During a 10-month period from June 1994 through March 1995, 347 patients received blood transfusion during the operation. Among them, we reviewed retrospectively the charts of 211 patients available. We analyzed the transfusion pattern of 47 patients whose postoperative hematocrit exceeded 32 percent to determine the magnitude and cause of unnecessary blood transfusion. RESULTS: The patients of postoperative hematocrit over 32 percent were 119 patients out of 211 patients(56.4%). The main cause of overtransfusion was no reevaluation of the patients hematocrit after the prior unit was given. CONCLUSIONS: Guidelines for transfusing patients must be constructed based on acceptable intraoperative hematocrits. Unnecessary transfusion can be decreased when the transfusion done according to the guidelines, insisting on each reevaluation of the hematocrit prior to the administration of unit of blood.

This is study was performed to assess socioeconomic status and physical health status of middle-aged men (40's~60's) in Ganghwa country. We interviewed 1,267 middle-aged men (602 male, 665 female) by trained interviewers using structured questionnaires including demographic information, general health status, and anthropometric measurements. And all the data were analyzed by chi-square test, Student's t-test and one-way ANOVA using SPSS 12.0 version at p<0.05. These results were that males were higher than females in educational levels (p=0.000) and most of them decreased according to age in educational levels (p=0.000) and family income (p=0.000), and prevalence of chronic diseases (p=0.000): stomach-duodenum disease, fracture, arthritis, or hypertension. They took to the health information on TV and radio and their health managing methods were exercise and walking and resting and diet regulation. Body Mass Index (BMI) was decreased in older males (p=0.024) but increased in older females (p=0.001). In females, obesity prevalence of 40's, 50's and 60's was 31.3%, 49.7% and 48.0%, respectively. Waist circumference was the highest in 50's males (p=0.015), but hip circumference was the highest in 50's females (p=0.015). Waist-hip ratio (WHR) increased in older males (p=0.028) and females (p=0.000). In spite of the subjects were engaged in agriculture and fishery and had desirable lifestyles, obesity rate especially abdominal obesity, was the serious problem. Socioeconomic status, especially education and income were related to SRH (p=0.006, p=0.000), chronic disease (p=0.000) and BMI (p=0.028, p=0.000). Therefore, it is necessary that the public health policy and nutrition education programs to alter lifestyles and to improve health preservation and health promotion in the farming and fishing communities.

Pacemaker malfunctions are secondary to alterations of the preset pacing rate, irregular pacing failure of sensing, failure of cardiac capture or depolarization, and various combinations of these events. A 76 years old male patients was admitted due to pacemaker malfunction. 2 years ago, he was diagnosed as complete atrioventricular block. And then bipolar permanent pacemaker was implanted. Since then syncopal attack developed repetitivly. 12 lead ECG and 24 hour holter moniter monitoring, revealed pacing and sensing failure, thus we converted bipolar system into unipolar system. since then syncopal attack did not developed again.

PURPOSE: The purpose of this study was to assess the treatment effect of extracorporeal magnetic innervation (ExMI) therapy, and determine how long the effect of this treatment lasts. MATERIALS AND METHODS: Among the demonstrable stress urinary incontinent patients, 28 were selected. Before the ExMI therapy, voiding diary, incontinence episodes, pad test, and quality of life questionnaires were evaluated. The treatment was performed for 30 minutes, 3 times a week, for 6 weeks. All of the evaluations were repeated at the first and sixth months following treatment. The treatment outcomes were classified as: cure, good, fair, poor and failure, according to a new outcome score. RESULTS: The overall cure rate was 35.7% (10/28) by the 1st month and 17.9% (5/28) by the 6th. From further a classification, the cure rate in grade I was 43.8 (7/16) and 25% (4/16) by the 1st and 6th months, respectively, and in grade II were 25 (3/12) and 8.3% (1/12) respectively. Incontinence episode was reduced from 4.2+/-2.8 to 1.5+/-1.5 and 2.8+/-2.3 by the 1st and 6th months, respectively. The urine loss was reduced from 21.0+/-31.4g to 6.0+/-8.2g and 14.0+/-24.7g by the 1st and 6th months, respectively. The results were statistically analyzed using Wilcoxon rank sum and Fisher's exact tests. CONCLUSIONS: It was suggested that the ExMI therapy was an effective treatment for stress urinary incontinence, but its effect decreased over time. In order to sustain, or improve its effect, a regular interval, or prolonged ExMI therapy, would be need

BACKGROUND: The purpose of this study was to find out the cause of discrepancy between various automated immunoassays for 25-hydroxy-vitamin D (25-[OH]D). METHODS: National Institute of Standards & Technology Standard Reference Material (SRM) 972a is SRM for 25-(OH)D and consists of 4 vials of frozen serum with different concentrations of 25-(OH)D. Each concentration was measured 6 times in 3 different immunoassays: ADVIA Vitamin D Total assay (Siemens Healthcare, Erlangen, Germany), ARCHITECT 25-(OH)D (Abbott Laboratories, Abbott Park, IL, USA), and COBAS Vitamin D Total assay (Roche Diagnostics, Basel, Switzerland). RESULTS: When using the certified reference values of SRM 972a as it is, discarding the cross-reactivity of each immunoassay, for ADVIA, the coefficient of determination (R2) as a score of regression analysis was 0.8995 and maximal difference between measured value and certified reference value was 3.6 ng/mL in level 3. The R2 and maximal differences of ARCHITECT were 0.5377 and 6.9 ng/mL, respectively, in level 4. Those of COBAS were 0.3674 and 22.3 ng/mL, respectively, in level 4. When considering cross-reactivities of each immunoassays to various 25-(OH)D metabolites, the ADVIA had R2 and maximal difference of 0.9254 and 3.3 ng/mL, respectively, in level 3. For ARCHITECT, the R2 and maximal differences were 0.7602 and 5.1 ng/mL, respectively, in level 1. Those of COBAS were 0.9284 and 4.9 ng/mL, respectively, in level 1. CONCLUSIONS: The cause of discrepancies between vitamin D immunoassays was mainly on the difference in cross-reactivities to various vitamin D metabolites. The discrepancies can be considerably decreased by considering cross-reactivities of each immunoassay.

BACKGROUND: Perfusion scintigraphy with dipyridamole have been reported to be useful for diagnosis of coronary artery disease and the assessment of the presence and extent of myocardium at ischemic risk, especially in patients who can not undergo dynamic exercise testing. Dipyridamole, pharmacologic coronary vasodilator, also induces fall in blood pressure and rise in heart rate. The purpose of this study was to answer the question if dipyridamole induced peripheral hemodynamic responses were related to chest pain, ST changes on EKG, scintigraphic defect or extent of coronary stenosis. METHODS: Dipyridamole 99mTc-MIBI myocardial scintigraphy and coronary angiography on 43 subjects who were suspected to have coronary artery disease. The peripheral hemodynamic response was graded as absent(group 0) if there was a < or =10mm fall in systolic blood pressure (SBP) and/or < or =10 beats/min rise in geart rate(HR) ; moderate(group 1) if there was >10 but < or =20mm fall in SBP and/or >10 but < or =20 beats/min rise in HR ; and marked (group 2) if there was >20mm fall in SBP and/or >20 beats/min rise in HR. RESULTS: The overall diagnostic sensitivity and specificity for coronary artery disease of dipyridamole perfusion scintigraphy were 68%, 83% while per vessel sensitivity and specificity for coronary artery disease were 66%, 97%. The numbers of induced chest pain and ischemic ST changes among hemodynamic subgroups, were 40%, 40% in group 0, 33%, 27% in group 1 and 50%, 40% in group 2 without significant difference in each hemodynamic subgroups. Either the numbers of diseased coronary arteries or the numbers of patients demonstrationg reversible scintigraphic defects were not statically different among each subgroups. CONCLUSION: Although the peripheral hemodynamic response dose not always correlate with its central coronary effect but dipyridamlole 99mTc-MIBI myocardial perfusion scintigraphy is an useful test for diagnosis of coronary artery disease.

The subarachnoidal or epidural opioid reveals excellent analgesic effect for postoperative pain and intractable cancer pain, but its side effects such as nausea, vomiting, voiding difficulty, pruritus and respiratory failure limit its use. There were many studies for decreasing frequency and severity of side effects and reinforcing the analgesic effect of opioid by administrating other drugs. Clonidine is one of such drugs which is able to be administered epidurally with opioids for that purpose. We studied the changes of cardiovascular response, analgesic and sedative effect according to the dose of epidural clonidine. The analgesic effect of epidural clonidine was investigated in 30 patients who underwent anal surgery with epidural anesthesia using 15 ml of 1.5~2 % lidocaine.The time of maximal intensity of pain after disapperance of injected lidocaine was checked. Thirty patients were divided into three groups randomly. In group 1 (n=10), the dose of epidural clonidine was 50 ug; Group 2 (n=10) was 150 ug; Group 3 (n=10) was 450 ug. Changes in the arterial pressure, pulse rate, sedation state and SpO2 were observed before and during 60 minutes after epidural clonidine administration. And the analgesic effect was assessed by measuring VAS pain score. Blood pressures and pulse rates decreased according to increase of dosage of clonidine. Group 1 showed the analgesic effect of 34%, group 2 showed 77% and group 3 showed 81% at 60 minutes after administration. Sedation effect was seen in group 2 and 3 but SpO2 was not decreased significantly. We thought that the respiratory depression of epidural clonidine was not so significant to limit the use for the postoperative pain control. We conclude that it is better to administer clonidine with opioids epidurally than clonidine slone to get better analgesic effect and less sedative effect, because the analgesic effect of epidural clonidine increases according to increase of dosage but the sedative effect increases also.
