Screening is for the early detection and treatment of diseases in prior to development of symptoms, so that more favourable prognosis could be obtained. To evaluate efficiency of screening test for cervical neoplasms, we compared the histopathologic stages of asymptomatic cervical neoplasm patients diagnosed by screening test, with those of symptomatic patients confirmed by pathology. Total 1,120 cases of cervical neoplasm patient, diagnosed at Kang-nam St. Mary's hospital from Jan. 1990 to Dec. 1996, were reviewed by chart, and classified as asymptomatic and symptomatic group based on the presence of subjective symptoms on their hospital visit. Their histopathologic stages were analysed. The results were as follows, 1. From the total of 1,120 patient, asymptomatic group comprised 264 cases (25.5%). Asymptomatic proportion increased 15.3% in 1991 to 34.7% in 1996. 2. Mean age for the occurrence of cervical neoplasm was 44.3 +/- 10.4 years for the asymptomatic group, and 49.3+/-13.2 years for the symptomatic group, showing statistically significant differences(p=0.001). 3. Among the study subjects, 465 cases(45.0%) had CIS(carcinoma in situ), and 569 cases(55.0%) had invasive cancers. 4. Percentage of cervical neoplasm patient diagnosed at asymptomatic stages were 45.8% in twenties, 32.0% in thirties, 27.7 % in forties, 21.7% in fifties, 18.7% in sixties and 1.8% in above seventies, showing statistically significant differences according to age group(p=0.001). 5. In thirties, 87.2% of the asymptomatic patients were diagnosed as CIS and 45.0% of symptomatic patient were diagnosed as CIS. With increment of ages, CIS proportion were markedly decreased. 6. 76.9% of asymptomatic patients were diagnosed as CIS, and 34.0 % of symptomatic patients were diagnosed as CIS, suggesting screening test at asymptomatic stage can increase CIS proportion. 7. CIS proportion of asymptomatic patient was highest in thirties(40.4%) and 2nd highest in forties(34.0%). Screening test for cervical neoplasm should be actively carried out from the thirties.

Postpubertal mumps may result in ochitis and permanent testicular atrophy may develop following infection. This present study was initiated to evaluate the preventive effect of interferon-alpha2B on infertilty after mumps orchitis. There were 21 patients with mumps orchitis between May 1990 and June 1997. Patients were randomly distributed into 2 groups: group 1 patients (n=13) maintained therapy with interferon-alpha2B (3x10(6) IU per day) and group 2 were managed by conservatively. All of the patients were evaluated with testis size measurement, mumps virus titer, hormone level, and if possible semen analysis. For group 1 patients symptoms disappeared within 2 to 3 days and the volume of testis returned to normal within 11 days and testis atrophy was not observed in all patients in follow up. But asthenospermia was continued in 4 patients (unilateral 2, bilateral 2). For group 2 patients symptoms disappeared within 5 to 6 days and the volume of testis returned to normal within 10 days and testis atrophy was observed in 3 patients (unilateral 2, bilateral 1) in floow up. Asthenospermia was continued in 4 patients (unilateral 2, bilateral 2). Sperm count and morphology were recovered all the recover in group 1, 4 patients had persistent reduced sperm count and morphology in group 2, respectively. These observations suggest that systemic interferon-alpha2B treatment is highly effective in preventing infertility as well as testicular atrophy after mumps orchitis.

Urinary hippuric acid was analyzed by gas chromatography/mass spectrometry method. A simple and economical derivatization procedure using excessive methanol in acidic condition was adopted to esterify hippuric acid. Quantitative analysis was performed with two internal standards, heptadecanoic acid and hydrocinnamic acid, to evaluate the derivatization procedure as an analytical method. Using the standard addition method, linear and reproducible calibration curves were obtained for both internal standards. Calibration experiment showed that good quantitative result could also be obtained with the calibration curve obtained without urine matrix. Recovery rates for the urine samples were in the range of 95.6~111.4%. Using hydrocinnamic acid as internal standard, analysis time could be reduced.

Before and after conducting the health promotion program by group occupational health service during 5 years, we surveyed knowledge, attitude and practice about general health(30 items) and occupational health (30 items) among 25 small and medium scale industry workers (before : 355 workers, after : 279 workers) for evaluation of effectiveness. The scores of knowledge for smoking, drinking, cholesterol, mental stress, management of hypertension, and risks in younger or women workers were significantly increased after conducting group occupational health service. The scorers of attitude for controlling of fatty food consumption and cleaning workplace and bathing for health and that of practice for taking the periodic health examination and choking blood pressure were significantly increased but most of items in attitude and practice didn't be changed after services. According to sex, the scorers of men were significantly increased in knowledge of general health, but there were not significant differences in age, job status and work duration group. In conclusion, through the group occupational health service during 5 years, only the scores of knowledge in general health were increased. It suggested that the effective program which can change workers' attitude and practice for health promotion, should be developed and conducted in small and medium scale industry workers.

Executing detailed examination for cumulative trauma disorders(CTD) for all the workers with repetitive operators is not desirable considering the cost-effectiveness. Screening test with subjective symptoms, physical examination and hand strength test to detect the proper subject for secondary detailed examination is needed. The purpose of this study was to determine normal values for grip and pinch(tip, lateral and palmar) strength to be used as a screening tool for CTD. Total of 1,018 healthy subjects without related past occupational or medical history were examined with Jamar dynamometer and pinch gage. Each hand was checked twice in a posture recommended by American Society of Hand Therapists, and higher value was accepted. The results were as follows, 1. The mean grip strength of right hand in right-handed man was 47.7 kg, and 27.2 kg in woman. The mean tip pinch strength of right hand in right-handed man was 6.2 kg, and 3.9 kg in woman. The mean lateral pinch strength was 9.0 kg in man, and 5.5 kg in woman. And the mean palmar pinch strength was 9.3 kg in man, and 6.9 kg in woman. There was no significant differences in dominant hand power according to the right or the left hand dominances. 2. Selecting 10 percentile value for screening criteria for CTD, 10 percentile value of trip strength was 38 kg in man and 20 kg in woman. And that of tip pinch strength was 4 kg in man and 2 kg in woman, lateral pinch strength was 6 kg and 4 kg each, palmar pinch strength was 6 kg and 5 kg each. 3. Grip and all three pinch strengths of man showed positive correlation with age, height and weight, but in the cases of woman, only grip strength showed positive correlation with height and weight. 4. In cases of right-handed persons, dominant hand showed higher grip strength compared to the contralateral hand in 70.9% of males, and 72.9% of females. And the mean differences of bilateral grip strength was 2.7 kg(5.2%) in male, and 1.7 kg(5.7%) in female. But in the cases of left-handed persons, dominant hand did not show the significant difference in strength compared to the contralateral hand.

We report a case of spontaneous uretreral rupture cured by conservative management. The patient(65-year-old man) who had left flank pain for 6 days was presented to our hospital. He had no history of trauma and previous urologic problems. Diagnosis was made by IVP and abdominal CT scan, which showed extravasation from left upper ureter and accumulation of a large amount of contrast media in the retroperitoneal space. On ureteroscopy, partial obstruction of left lower ureter was found and the upper ureteral mucosa showed diffuse erythematous changes. The rupture site with erythematous edema and some necrotic tissues was identified in lateral wall near ureteropelvic junction. A guide wire was passed upward the rupture site under direct vision of ureteroscope and then 6 Fr. double J stent was successfully palced. The stent was removed 4 weeks after the placement. Followup IVP showed good urinary drainange without evidence of extravasation.

Ambient air monitoring(environmental monitoring) and biological monitoring of mixed organic solvents exposure have been used in exposure assessment of these compounds in the work environment. Environmental monitoring is more useful when assessing low level exposure to these compounds. The specific objectives of this study were to measure air organic solvent levels in the work environment, to test the agreement of items measured in this study with items which have been reported to the administrative agency, and finally to evaluate the appropriateness of environmental monitoring items. The study subjects were 13 small companies in which less than 300 employees were working and presumably exposed to mixed organic solvents(e.g. automotive repair and painting, 6; textile dyeing, 2; printing, 2; electronics, etc, 3). Personal air samplings were performed by the flow-lite sampling pump(MSA) and the 600mg charcoal tube with air velocity of 100ml/min for qualitative analysis and 2l/min for quantitative analysis. Samples were analysed by gas chromatography/mass spectrometry(Hewlett-Packard 5890/5970). High levels of toluene, n-hexane, and MIBK were detected in most study companies and low levels of ethylbenzene, xylene, n-butylacetate were also detected. When these measured items were compared with those of reported items, only 6 of 13 companies showed relatively good agreement between them. Two companies failed to report items exceeding the limit value. In conclusion, qualitative analysis of ambient air organic solvents seemed to be as important as quantitative analysis of these compounds and a periodic evaluation of monitoring items reported to the administrative agency should be required.

OBJECTIVES: Little is known about the influence of urinary incontinence and depression on individual's QOL(Quality of life). We aimed to clarify how the interaction between urinary incontinence and depression influences one's QOL. METHODS: A total of 1262 patients were enrolled in this study from April, 2011 to July, 2011. We estimated the severity of depressive symptoms and QOL, using SGDS-K, EQ-5D. We also investigated the morbidity of urinary incontinence for each patient in person or by questionnaire. Comparisons of QOL between groups with or without depression, with or without urinary incontinence were established using t-test, ANOVA and Scheffe's post hoc analysis. The interaction between urinary incontinence and depression was analyzed by each domain of QOL, using multiple regression analysis. RESULTS: Patients with depression and urinary incontinence showed significantly higher EQ-5D scores on every domain of QOL than other patients, which means significantly lower QOL. Patients with depression, no urinary incontinence reported lower QOL, especially in the domain of ‘usual activity’, ‘anxiety’ and ‘visual analogue scale(VAS)’, whereas those with urinary incontinence, no depression showed lower QOL in ‘motility’, ‘usual activities’ and ‘pain’ domain. Statistically significant interaction effects of two diseases were observed in the domain of ‘VAS’, ‘self care’ and ‘anxiety’. CONCLUSIONS: Comorbidity of urinary incontinence and depression showed significantly lower QOL of patients, compared with urinary incontinence or depression respectively, which implies additive interaction effects of the two diseases. Optimal diagnosis and treatment of depression should be emphasized for patients with urinary incontinence.

PURPOSE: To investigate the incidence of thromboembolic events and complications related to bleeding after total knee arthroplasty (TKA) with a mechanical compression device alone or in combination with low-molecular-weight heparin (LMWH). MATERIALS AND METHODS: A total of 489 TKA patients (776 knees) were retrospectively reviewed for the incidence of thromboembolic events and complications related to bleeding. While 233 patients (354 knees) were treated with a mechanical compressive device without LMWH, 256 patients (422 knees) were treated with the mechanical compressive device along with LMWH. RESULTS: The incidences of deep vein thrombosis (DVT) and pulmonary embolism (PE) were 15 of 375 knees (4.0%) and 5 of 375 knees (1.3%), respectively, in the group that used only a mechanical compressive device, and 14 of 401 knees (3.4%) and 5 of 401 knees (1.2%), respectively, in the group that used the mechanical compressive device with LMWH. There was no significant difference between the two groups (p=0.125 and p=0.146, respectively). The postoperative hemovac drainage amount was 635±57 mL in the group with a mechanical compressive device only and 813±84 mL in the group with the device and LMWH; therefore, the amount of drainage was significantly greater in the latter group (p=0.013). CONCLUSIONS: Mechanical compression alone for prophylaxis against DVT and PE after TKA can be an attractive option in Korean patients.

The tongue is one of the most common sites of oral cancer. Glossectomy is known as the gold standard for tongue cancer treatment. However, surgical removal can lead to reduced mobility of the tongue and the patients may have difficulty performing normal oral functions like swallowing and pronunciation. Therefore, additional prosthetic consideration to supplement the function of the impaired tongue is needed for oral rehabilitation of such patients. Palatal augmentation prosthesis helps the tongue to reach the palate by lowering the position of the palatal polished surface. The oral functions of the patients with limited tongue mobility can be improved by the prosthesis. In this case, palatal augmented maxillary denture and conventional mandibular denture were fabricated for the completely edentulous patient with reduced tongue mobility after glossectomy due to tongue cancer. As a result, the oral functions of the patient were improved with the prosthesis.
