BACKGROUND: Noninvasive estimation of pulmonary artery pressure is an important component of echocardiographic studies. A number of methods are available for estimation of pulmenary pressure, each with varying degrees of reported accuracy. To assess accuracy and difficulties, noninvasive pulmonary artery pressure estimates were performed in infants and children with congenital heart diseases. METHODS: Noninvasive estimates from 8 methods were compared with catheterization measurements. Systolic pressure was estimated by the Burstin method and from perak tricuspid regurgitation velocity, and also from systolic pressure gradients through the VSD(ventricular septal defect) and PDA(patent ductus arteriosus). Mean pressure was estimated by acceleration time divided by ejection time measured from Koppler spectrum obtained at the right ventricular out flow tract. Diastolic pressure was estimated from pulmonary regurgitation velocity spentrum at end-diastolic, and also from diastolic pressure gradient through the patent ductus arteriosus. RESULTS: IN systolic pressure, Burstin and tricuspid regurgitation velocities estimates correlated significantly(r=0.92, 0.90 respectively), whereas VSD and PDA estimates correlated less well with catheterization estimates(r=0.83, 0.65 respectively). The mean pressure, measured from RVOT(right ventricular outflow tract) Doppler spectrum corresponded well with catheterization pressure(r=0.89), whereas those obtained from the main pulmonary artery correlated less well(r=0.74). The diastolic pressure estimates from pulmonary regurgitation velocity spectrum, revealed good correlation(r=0.79), but those from diastolic Doppler spectrum at PDA correlated less well with catheterization estimates(r=0.63). CONCLUSION: All of eight Doppler echocardiographic methods seemed to be easily performable for estimation of pulmonary artery pressure. But, the degree of accuracy was variable. Because a pressure estimante from only a single method may be in error, care should be taken in combining use of other(one or two) methods.

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: A heterotopic pancreas is defined as one for which pancreatic tissue is present outside its usual or habitual location and without an anatomic relation either of continuity or of vascularization with the pancreas proper. Most heterotopic pancreases are incidentally encountered during surgery, and on rare occasions, epigastric pain, weight loss, hemorrhage, gastric outlet obstruction, and intussusception have been directly attributable to the presence of a heterotopic pancreas. The purpose of this article is to report the clinical characteristics of the heterotopic pancreas. METHOD: We retrospectively observed 24 patients, who had been pathologically proven to have a heterotopic pancreas, at the Department of Surgery, Korea University Hospital, from Jan. 1990 to Dec. 1998. RESULTS: 16 of the 24 cases were found incidentally during operations due to by other primary diseases; 8 cases were symptomatic. The ratio of males to females was 1.18:1 and most common sites were the stomach and the duodenum (71%). The mean size of the lesion was 1.26 cm, and the sizes in symptomatic cases were larger (mean 1.89 cm) than those in cases where the lesions were found incidentally (mean 0.94 cm). We experienced a case of a ductal adenocarcinoma originating from the heterotopic pancreas in the jejunum of a 73 year old man. CONCLUSION: A heterotopic pancreas should be considered in the differential diagnosis of submucosal tumors, polyps, ulceration, and intestinal tumors, When suspected, an intraoperative frozen section is recommended, and the range and the method of the operation should be decided based on the results of the frozen section.

BACKGROUND: The usage of appropriate disinfectants is essential for infection control in a hospital. Inadequate use of disinfectants is the cause of human or environmental toxicity and is a waste of cost. The objective of this study was to describe the status of the usage of disinfectants in Korean hospitals. METHOD: One hundred and eighty three hospitals of over 300 beds were investigated by a questionnaire distributed by mall. Data collection was done on November 1999. The questionnaire was made by the Association of Infection Control Nurses in Korea, based on references and protocols of the Korean Society of Nosocomial Infection Control. Numerical and percentage data were analyzed by SPSS. RESULTS: The collection rate of the questionnaire was 43.7% (80/300). Thirty five hospitals (46.7%) had an official process in selecting disinfectants in their hospitals. Regarding skin antiseptics, 10% povidone iodine and 70% alcohol were commonly used in skin preparation for intravenous catheterization or pre-operative skin disinfection, For disinfection of mucosal membranes such as mouth and periurethral area, 3% boric acid solution or 3% H202 were used. Most of the hospitals decontaminated contaminated medical instruments manually with dodecyl diamino ethyl glycine (20.8%). glutaraldehyde (15.6%). quaternary ammonium compounds (13.8%), virkon (12.3%) and sodium hypochlorites (11.7%). Glutaraldehyde and virkon were frequently used for disinfection of endoscopes. Sodium hypochlorites (48.9%) and quaternary ammonium compounds (19.8%) were the most commonly used environmental disinfectants. Some noticeable problems in disinfectants were as follows. First, for mouth care, many hospitals (41.7%) over-used boric acid, which has cumulative toxicity for humans. Second, many hospitals had an incorrect protocol of disinfecting endoscopes. Third, for environmental decontamination and instrument cleaning, some hospitals used high level disinfectants such as glutaraldehyde, which is too costly and provides unnecessary safety problems. Fourth, after patient discharge, many hospitals did not use disinfectants at all. Considering the specific Korean medical environment of high incidence of multi-drug resistant microorganisms, use of disinfectants for discharged environments may be warranted. CONCLUSION: This study included only hospitals of over 300 beds, which has a limitation in representing the status of disinfectants usage in a country. However, significant problems from misunderstanding the basic principles of disinfectants and misusages of disinfectants were observed in this investigation. These observations will provide useful information for designing a guideline for the appropriate uses and for efficient education of disinfectants, and also for planning a national control program for proper disinfectants usage in this country.

PURPOSE: This study was to examine the effectiveness of exercise for bone mineral density (BMD). METHODS: Four investigators reviewed English articles from Pub Med and CINAHL, selecting randomized controlled trials on exercise programs for middle-aged and older women. Out of 25 studies identified, 14 that satisfied with the inclusion criteria were included in the meta-analysis. The quality of the studies was assessed using recognized methods and the effect size was calculated as a Hedges' g using Comprehensive Meta-analysis Version 2.0. Primary outcomes were changes in BMD at femoral neck, trochanter, and lumbar spine. Subgroup analysis included changes in BMD according to exercise style. RESULTS: Weight bearing exercise was effective (Q = 20.1, p > .05, ES = 0.32), and resistance exercise was effective in case of comparing to pre and post intervention (Q = 4.15, p = .98, ES = 0.14). At the femoral neck, 9 study groups were homogeneous and the experimental groups demonstrated a positive effect on BMD (Q = 19.5, p > .05, ES = 0.33). In contrast, marked heterogeneity (Q = 33.3, p < 0.01) was apparent in 7 study groups evaluating trochanter. CONCLUSION: These findings suggest that weight bearing is effective for BMD of the femoral neck, and is relevant to the non-pharmacological treatment of bone loss for middle-aged and older women.

The distribution of pemphigus subclass autoantibodies in a patient with pemphigus vulgaris (PV) has been investigated by semiquantitative indirect immunofluorescence (IIF), using the HP series monoclonal antibodies specific for four human IgG subclasses on human foreskins. IgG1 and IgG4 intercellular substance-specific autoantibodies were detected in the serum of the patient, whereas IgG2 and IgG3 autoantibodies were absent. In addition to foreskins, human tonsillar epithelia were used as substrates of IIF for detecting the PV autoantibodies and it was one of satisfactory substitutes for monkey esophagus.

PURPOSE: The purpose of this study was to examine the relationship between spirituality and a fighting spirit among the patients with cancer. METHODS: The participants were 223 patients diagnosed stomach, colorectal or breast cancer, and who were in chemotherapy or follow up care. The study design was cross-sectional at the time of the data collection. The degree of spirituality was measured by the Korean version of WHOQOL Spirituality, Religiousness and Personal Beliefs (SRPB) Pilot Test Module, and fighting spirit was measured by the scores of Mental Adjustment to Cancer(MAC) scale. RESULTS: The score of love appeared to be higher in the patients with follow up care than the patients with treatment(p<0.05) and the score of believing was much higher in patients with recurrence than the patients without (p<0.05). There was a statistically significant correlation among hope, believing, love, forgiveness and acceptance, and fighting spirit. In the multiple regression analysis, hope and believing explained much variance of the fighting spirit. CONCLUSION: These finding showed that the more hopeful and believing patients with cancer had higher scores of fighting spirit, which was known to be one of the most active coping style in adjusting to cancer.

A perplexing developmental error is 46,XX congenital absence of vagina ( Mayer-Rokitan-sky-Kster-Hauser syndrome, Mullerian dysgenesis, vaginal aplasia ). The Mayer-Rokitansky-Kster-Hauser syndrome refers to the climical entity consisting of primary amenorrhea associated with congenital absence of the vagina, 46,XX karyototype, a rudimentary uterus or complete absense, normal overian function and normal ovulation, normal female breast development, body proprotion and body hair, frequent association of renal, skeletal and other cpngenital anomalies. This syndrome results from agenesis of both Mllerian ducts or from a failure of the Mllerian ducts to estavlish a proper communication with that part of the vagina from the urogenital sinus. A case of mayer-Rokitansky-Kster-Hauser syndrom was reviewed briefly.

Sister chromatid exchanges (SCEs) observed by means of bromodeoxyuridine substitution and fluorescence plus Giemsa (FPG) technique were proposed as a sensitive and quantitative assay for mutagenicity and cytotoxicity in short-term cultures of phytohaemagglutinin (PHA)-stimulated human lymphocytes. Therefore, this study was carried out to investigate the relation between anticancer agents and cytotoxic effects. Chromosomal analysis was performed on metaphase cells that had divided one, two, or three or more times after treatment for SCEs, mitotic indices (MI) and cell cycle kinetics by FPG technique. The results indicate that anticancer agents led to a dose dependent increase in SCE frequency except methotrexate. But, highly inhibited mitotic indices and delayed cell cycle kinetics were observed except for cyclophosphamide. The author suggest that the difference of SCE frequency is due to the differences in the cytotoxic action of anticancer agents, but although the induction of SCEs has a correlation with cell cycle delay, in some cases the induction of SCEs is not always related to cell cycle delay because of different cytotoxic action of anticancer agents.
