The coronary arteries are also subject to congenital anomalies of both minor and major consequence. Hemodynamically significant primary anomalies of the coronary arteries are those which alter myocardial perfusion. There are four major types : coronary artery fistula, origin of the left voronary artery from the pulmonary artery, congenital coronary stenosis or atresia and origin of the left or right coronary artery from the opposite sinus of Valsalva with subsequent passage of the vessel between the aorta and right ventricular infundibulum. Minor anomlies are the variation of the origin of the coronary arteries from the aorta with normal distal circulation. We can see more coronary anomalies associated with congenital cardiac anomalies, probably representing a circulatory response to the primary intracardiac defect. We present a total of 76 cases of congenital coronary anomalies, reviewing 3946 cases of angiocardiography or selective coronary arteriography, performed during last 8 years at Sejong General Hospital.

PURPOSE: The purpose of study was to evaluate the reliability of transrectal ultrasonography (TRUS) in the prostate volume measurement. MATERIALS AND METHODS: Forty-one patients underwent two TRUS examinations during two independent sessions to measure the three-dimensional diameters and volume of the prostate. The difference between the two TRUS examinations was evaluated, and the reliability of TRUS was assessed using the intraclass correlation coefficient (ICC), coefficient of variation (CV), and Bland and Altman plot. RESULTS: The patients were divided into two subgroups by two observers those with the mean prostate volume same or greater than 30 ml (group A) and those with the mean prostate volume less than 30 ml (group B). A prostate volume difference greater than 5 ml and 10 ml between the two TRUS examinations was more frequently included in the group A than in the group B (43% and 33%, 5% and 0%, respectively) (p < 0.05). ICC and CV showed poor reliability for measuring the prostate height, length and volume in the group A (ICC for width, height, length and volume < 0.75, CV for volume =12.97%). CONCLUSION: Prostate volume measurement by TRUS may be unreliable in large prostates with unreliable measurement of the height and length being the primary limiting cause.

PURPOSE: Leigh syndrome is a kind of mitochondrial disease with a pathological production of lactate and variable clinical manifestations. Recently biochemical assay of the mitochondrial enzyme activity and MRS are becoming a powerful tool for the definitive antemorterm diagnosis of this disease. The aim of this study was designed to determine the usefulness of biochemical enzyme assay and MRS in Leigh syndrome. METHODS: A clinical study of 8 cases of pediatric patients were diagnosed as Leigh syndrome on the basis of clinical manifestations and MRI features at the department of pediatrics, Ulsan university hospital, from July, 1992 to June, 1997. Biochemical enzyme assay of the cultured skin fibroblasts was consulted to hospital for sick children, Toronto, Canada. Cerebral lactates were detected on MRS were analysed in relation to the MRI findings and lactate levels in the CSF. RESULTS: 1) Age at diagnosis ranged from 7 months to 8.9 years; seven were boys and one was girl. 2) Main clinical symptoms were as follows in the order of frequency; seizure(75%), ophthalmoplegia(50%), hemiplegia(50%), hypotonia(50%), respiratory difficulty(50%), developmental delay(38%), consciousness change(38%), mental retardation( 25%). 3) Anatomical locations of the focal lesions detected on the initial MRI were as follows in the order of frequency; putamen(75%), caudate nuclei(63%), medulla oblongata (18,50%), substantia nigra(38%), thalamus(38%). 4) Biochemical enzyme assay revealed deficiency of NADH cytochrome c reductase (complex I) and deficiency of cytochrome c oxidase(complex N) respectively in 2 patients who had markedly elevated serum and CSF lactate levels and lactate/pyruvate ratio. 5) Cerebral lactates were detected by MRS from 6 lesions of 1 week-4 months old in 6 patients who had normal or mildly elevated serum and CSF lactate levels and lactate/pyruvate ratio. CONCLUSION: MRS detected the brain parenchymal lactate non-invasively from the acute or subacute lesions. Therefore, combined evaluation by MRS and biochemical enzyme assay will provide an important information for the diagnosis and estimation of disease activity in pediatric patients who are suspected to have Leigh syndrome.

BACKGROUND: This is to evaluate the noisy environment, and to improve the hearing conservation program by analyzing the status of hearing loss and risk factors which cause hearing loss of Airlines pilots. METHODS: We reviewed Audiometric, Medical and Flying records of total 92 pilots under 55 years old . These subjects selected after excluding pilots with history of ear disease and ototoxic drug administration. The significance of the factors was analyzed by ANOVA and Regression test. RESULT: The mean age of pilots was 39.96 years old and the mean flight time was 5665.39 hours. The noise levels by aircrafts were mean 76.9dB and maximum 144.4dB in B737, mean 78.5dB and maximum 143.2dB in B747. The noise levels by headset were mean 72.1dB and maximum 144.1dB. The mean hearing threshold level was different with age groups. The older in age, the higher in the mean hearing threshold level at high frequency and left ear. It was increased the mean hearing threshold level (dB) at high frequency (4,000 Hz) by total flight time The effect on hearing threshold level at high frequency in left ear was statistically significant in total flight time (p=0.032). CONCLUSION: The noise level of aircrafts could cause noise-induced hearing loss in some pilots. Age and total flight time are within the range of possibility of hearing loss. The result of this study ascertained the possibility of hearing loss due to monaural-headsets on the left ear at 4,000 Hz. It is recommended that an effective hearing conservation program should be provided for the headset-wearing communication pilots.

Most trauma induced fistulas are direct communications between the intracavernous carotid artery and the cavernous sinus. Theses abnormal communications are characterized by high pressure, high blood flow and a clinically obvious constellation of symptoms and signs. We here in report a patient with traumatic carotid cavernous sinus fistula(CCSF). who developed central retinal vein occlusion(CRVO) during detachable balloon embolization. The mechanism of CRVO occurring during detachable balloon embolization. The mechanism of CRVO occurring during detachable ballon embolization for CCSF was discussed. We report this case with the review of previous reports.

OBJECTIVES: This study was to assess management outcome of patient undergoing decompressive craniectomy for space-occupying cerebral infarction refractory to medical treatment and to identify risk factors associated with unfavorable outcomes. PATIENTS AND METHODS: Between January 1999 and June 2004, total 20 patients were analyzed. The preoperative consciousness was rated using Glasgow Coma Scale (GCS). The clinical outcome was rated using Glasgow Outcome Scale (GOS) at 3 months follow up and divided into 2 groups;favorable outcome group (GOS> or =3) and unfavorable outcome group (GOS<3). The prognostic factors were analyzed multivariately. RESULTS: Fourteen patients were men and six patients were women (mean age, 58.7 yrs). Seventeen patients had right hemispheric infarction, and three patients had left hemispheric infarction. 16 patients had only middle cerebral artery (MCA) infarction, and 2 patients had combined anterior cerebral artery (ACA) or posterior cerebral artery (PCA) infarction respectively. Eleven patients showed anisocoria preoperatively. The mean time interval between symptom onset of infarction and operation was 61.5 hrs. 8 patients showed favorable outcome, and 12 patients showed unfavorable outcome. CONCLUSIONS: The existence of preoperative anisocoria and low preoperative GCS score were statistically significant prognostic factor related to unfavorable outcome.

PURPOSE: Recognition of impending death is crucial not only for efficient communication with the caregiver of the patient, but also determination of the time to refer to a separate room. Current studies simply list the events 'that have already occurred' around 48 hours before the death. This study is to analyze the predictability of each event by comparing the time length from 'change' to death. METHODS: Subjects included 160 patients who passed away in a palliative care unit in Incheon. The analysis was limited to 80 patients who had medical records for the last week of their lives. We determined 9 symptoms and 8 signs, and established the standard of 'significant change' of each event before death. RESULTS: The most common symptom was increased sleeping (53.8%) and the most common sign was decreased blood pressure (BP) (87.5%). The mean time to death within 48 hours was 46.8% in the case of resting dyspnea, 13.6% in the ease of low oxygen saturation, and 36.9% in the case of decreased BP. The symptom(s) which had the highest positive predictive value (PV) for death within 48 hours was shown to be resting dyspnea (83%), whereas the combination of resting dyspnea and confusion/delirium (65%) had the highest negative PV. As for the most common signs before death within 48 hours, the positive PVs were more than 95%, and the negative PV was the highest when decreased BP and low oxygen saturation were combined. The difference in survival patterns between symptoms and signs was significant. CONCLUSION: The most reliable symptoms to predict the impending death are resting dyspnea and confusion/delirium, and decline of oxygen saturation and BP are the reliable signs to predict the event.

In order to compare the amount of surgically induced astigmatism among sutureless group(Group 1),10-0 nylone suture group(Group 2),and using tissue adhesive group(Group 3),we analysed a series of rabbit cataract surgery cases in these three groups. We performed cataract surgery on 30 eyes of 15 rabbits by Irrigation and aspiration technique. After cataract surgery,10 eyes by sutureless technique,10 eyes were closed by conventional 10-0 nylon suture technique, and 10 eyes by tissue adhesive(Beriplast) technique.We collected keratometric data before and after surgery(At 1,2,4,8 weeks).In postoperative astigmatic change,three groups had the distinct features in the evolution for postoperative astigmatism.The group 1 showed early against-the-rule(ATR)astigmatism,which advanced ATR and showed about 0.5D astigmatic change at 8 weeks.The group 2 showed early with-the-rule(WTR)astigmatism about 1.13D,which advanced toward ATR from 1week.The group 3 showed little ATR about 0.2D,which was minimal change in astigmatism.At 8 weeks after operation,there was no signifi-cant difference in the astigmatic change among the three groups(P>0.05), which were no complications observed. In this study,the tissue adhesive(Beriplast)seem to be a simple,effective and less induced astigmatic changing corneoscleral suture technique than other suture techniques

OBJECT: This study was devised to examine the demographic characteristics, psychopathology and associated psychiatric disorder of the Kleptomania offenders. METHODS: Kleptomania offenders who was referred to the National Forensic Psychiatric Hospital was concerned. RESULTS: Most of the Kleptomania offenders were women(92.6%, N=25) and lived alone(71.4%, N=20). In their first stealing, 25(92.6%) reported stressful situation just before stealing behavior but at admission 14(51.9%) is reported. Kleptomania experienced physical and sexual abuse during childhood; 9(33.3%) in case of physical abuse and 12(44.4%) in case of sexual abuse. At admission, Most of them complains of depressive mood(88.9%, N=24) and anxiety(88.9%, M=24), and any disorders like delusion was rare(7.4%, M=2). Most of Kleptomania offenders were comorbid psychiatric disorder; mood disorder(48.1%, N=13), personality disorder(40.7%, N=11), psychotic disorder(25.9%, N=7), anxiety disorder(14.8%, N=4) and alcohol dependence(14.8%, N=4). 24(88.9%) responded to the psychiatric treatment and 16(59.2%) of them had good prognosis. CONCLUSION: Most of Kleptomania offenders were single women and were abused physically or sexually during childhood. They had comorbid psychiatric disorder that responded to the psychiatric treatment and had good prognosis.
