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.

A 70-year-old female Patient was admitted due to the impression of lung abscess via local clinic. Chest P-A showed air shadow containing huge mass lesion in the right lower lung field, pericardio phrenic angle. But the patient complained of only mild upper respiratioy tract infection symptoms and the laboratory tests were within normal limits. Barium enema and chest C-T taken right after barium enema were performad in suggesting of the diaphragmatic hernia. Barium tilled transverse colon and associated omentum were in the right anterior hemithorax surrounded by the hernial sac. The mass lesion shown in the chest P-A was compatible with the diaphragmatic hemia, Morgagni type. Operative reduction of the herniated bowel and simple closure of the diaphragm was performed.

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 number of old patients suffering from benign prostatic hyperplasia is growing. TURP is still "gold standard" of relieving infravesical obstruction due to BPH, but the persistently high postoperative morbidity after TURP recently spurred the development of less invasive treatment options. Laser ablation of the prostate is a relatively new surgical treatment for BPH. According to studies published to date, laser prostatectomy is a simple and effective BPH-treatment modality with a low complication rate. We carried out Nd : YAG laser prostatectomy under visual control (VLAP) in 57 patients with BPH, aged 53-80 years (mean: 64.9 years). Preoperatively, the maximal flow rate (Qmax) ranged from 6-14 ml/sec (mean: 9.5 ml/sec), the residual urine volume (RUV) was 20-300 ml (mean: 109 ml), and the I-PSS ranged from 18-28 (mean: 20.4). The prostatic volume, measured with transrectal ultrasonography, was 26-72 gm (mean: 43.3 gm). There was no significant changes of hemoglobin, hematocrit and serum electrolytes, perioperatively. In 6 patients (10.5%), retention was developed after removal of urethral catheter at postoperative fifth day and so urethral catheter was reinserted for 5-7 days. After 6 months, Qmax was 9-22 ml/sec (mean: 15.4 ml/sec), RUV was 0-50 ml (mean: 15 ml), the I-PSS was 4-21 (mean: 8.3), and the prostatic volume was 11.3-51.9 gm (mean: 24.9 gm). In most patients, the prostatic volume was decreased as 42.6%, and Qmax, RUV and I-PSS were improved noticeably. Transrectal ultrasonography showed defect of bladder neck and prostatic urethra during immediate postoperative period, but normal prostatic architecture after 6 months In conclusion, the laser prostatectomy for BPH is considered the most promising alternative to TURP.

Ocular ischemic syndrome is a disorder which includes the ocular symptoms and signs secondary to marked carotid artery occlusion, and typically occurs in elderly men. The ocular signs are unilateral injected eye with corneal edema, anterior uveitis, rubeosis iridis, neovascular glaucoma and cataract. On ophthalmologic examinations, unilateral venous dilation, narrowed retinal arteries, equatorial dot-blot hemorrhage and disc or retinal neovasculization are oftenly noted. The characteristic angiographic findings are delayed choroidal and retinal circulations associated with ipsilateral internal carotid artery occlusion. We have experienced a case of ocular ischemic syndrome with neovascular glaucoma, who is 61 year old man with right ocular pain and visual disturbance. Angiographic examinations revealed nearly total occlusion of ipsilateral proximal internal carotid artery.
