Post-caval or retrocaval ureter is a congenital anomaly of the vascular system. This anomaly almost. always involve the rt. ureter and occurs more frequently in male We have reported a 36 years male of rt. postcaval ureter that was resulted marked hydronephrosis due to compression of rt. ureter by vena cava. Three months after the operation, excretory urogram showed previous caliectasis and pyelectasis were moderately reduced and previous dislocated ureteral course was corrected.

The study conducted from May to September in 1994 to investigate applicability of the Hearing Handicap Inventory for the Elderly-Screening version(HHIE-S) in parallel with the puretone audiometer to the initial screening test of noise-induced hearing loss(NIHL) in some noise-exposed workers. Subjects were selected by systemic sampling that took every fifth person from 6,700 workers taking the annual occupational health examination by the department of Health Maintenance of Dongsan Hospital Keimyung University in Taegu. The authors administered the pure-tone audiometric test and self-reported questionnaire of HHIE-S including items of sociodemographic and job-related variables concurrently. The final subjects analysed were 1,019(488 males and 531 females) excluding fourteen persons who had many missing values in their questionnaires. The reliability coefficients of HHIE-S scale by Cronbach's alpha were 0.84. In the univariate analysis of hearing handicap measured by the HHIE-S, work duration, military service and the hearing threshold loss at 1kHz and 4kHz was the only selected variable explaining the hearing handicap in males and hearing threshold loss at 1kHz and 4kHz, age, and work duration were selected in females. In ROC curves for HHIE-S scores against NIHL as gold standard which was defined by the follow-up audiogram as more than 30dB of the average of 0.5/1/2kHz and 50dB at 4kHz, the optimal cutoff for the parallel HHIE-S appeared to be 8. The results suggest that HHIE-S appeared to have some reliability and validity in this data and might be used in screening NIHL in parallel with pure-tone audiometer in noise-exposed workers.

Reflex ileus in acute abdominal disease were produced frequently due to cholecystitis, cholelithiasis, abscess in pelvic, appendiceal and diaphragmatic etc. But we found that a functional type of paralytic ileus due to ureteral stonetr renal stone was commonly seen on the plain roentgenogram. In these functional type of reflex ileus due to urinary stone, distension of the small intestine withgas may interfere with an accurate detection of the stone. It may lead to confusion in detecting ureteral stone and obstructive ileus. In this report, we analyzed how many cases would show a functional type of reflex ileus in urinary stone cases. 1. In 200 cases of urinary stone, reflex ileus with urinary stone were produced in 49 cases(21. 5%) 2. Many cases of ureteral stone were found on lower third of the ureter. (99 cases) 28 reflex ileus cases in 99 cases were produced (29.2%) 3. In reflex ileus due to urinary stone, we classified them by sex, age, location and stone size. The stone was often masked by nausea, vomiting, abdominal distention and reflex ileus on plain roentgenogram. So it is necessary to perform a complete urological study to detect urinary stone.

OBJECTIVES: In order to evaluate the relationship between daily mortality and air pollution in Deagu for the period by the data from January 1993 to December 1997. METHODS: Deaths from accident(International Classification of Disease, Revision 9; 800-999 and Revision 10; V01- Y89) were excluded, Daily counts of deaths were analysed by general additive poisson model on the current day to 5 days before death, with controlling for effects of year, season, weather, weekday and holiday. The air pollutants examined included total suspended particulate (TSP), sulfur dioxide (SO,), nitrogen dioxide (NO,), carbon monoxide (CO) and ozone (03). RESULTS: Mortality was associated with NO, SO and CO in the air. Total mortality was estimated to increase by 1. 6 % (95 % CI 0. 3-3 %) with each 10 ppb rise in NOy on the current day and the preceding 1 day, 9. 4 % (95 % CI 7 13 %) with each 100 ppb rise in SOy and 2. 7 % (95 % CI 0. 1 5 %) with each 1 ppm rise in CO on the current day. The NO was more evident for the elderly who were 65 years and more. Cardiovascular-specific mortality was associated with the levels of CO on the current day. Respiratory-specific mortality was associated with the levels of TSP and NO 5 days before death. Excess mortality risk is clearly evident in the upper range of NO levels and increased monotonically with NO. CONCLUSIONS: This study suggested that the air pollution status below the current Korean ambient air quality standard might have an adverse effect on daily mortality. Then, it is impertive that the strategy for control of the air pollution-related daily mortality should be developed.

The dose-ralated dffects of intravenous infusion of thiopental and ketamine on the rat EEG were evaluated quantitatively by spectrum analysis of EEG recorded from the rat scalp. The anesthetics were infused into jugular vein at various rates ranging from 0 to 8ug/min/g body weight, and then bipolar EEG was recorded from the rat scalp and tis spectrum were calculated by powere wpectrum analysis. the density of each bands(delta 1-3.25, theta 3.5-7.75, alpha 8-12.15, beta 1.13-17.75, beta 2.18-20.75, and beta 3.21-31.75Hz) and total density were derived from the spectrums. In visual inspection of conventional EEG, low doses of thiopental increased the amplitudes of spinles. but higher doses decreased the amplitube gradually to electrical silence with increase of infusion rates. During infusion of higher doses of ketamine, two types of EEG were identified by the spectral patterns:The one was the cases in which increases of the power density over all frequency ranges were observed, and the other was those in which marked increases of density in specific frequency were observed. In thiopental infusion, the densities of all bands were increased to peak at 1~2ug/min/g and therafter were decreased with higher rates of infusion. In ketamine infusion, the densities were increased when the infusion rate was increased. These results suggest that, by the changing patterns of the band densities dervied from spectrum analysis of EEG, not only the effect on EEG of thiopental of tetamine can be quantified but also their differences of mechanisms of action on brain be reflected.

Posterior reversible encephalopathy syndrome (PRES) is a transient condition characterized by altered mental status, seizure, headache, and visual disturbance with typical neuro-imaging findings in the bilateral parieto-occipital regions. Clinicians should be aware of this syndrome because delayed diagnosis and treatment result in irreversible neurologic deficits. We present the case of a 77-year-old male diagnosed with PRES in the setting of postoperative critical illness caused by small-bowel strangulation.
