OBJECTIVES: The purpose of this study was to determine the clinical significance of residual amniotic fluid volume, as measured by the amniotic fluid index(AFI), on the prediction of latency period and perinatal outcomes in patients with preterm premature rupture of the membranes(PPROM). METHODS: Study population consisted of 103 singleton pregnancies with PPROM between 24 and 34 weeks' gestation. Amniotic fluid index was determined using transabdominal ultrasound at admission. Latency period was defined as time interval in hours between admission and delivery. All medical records of mothers and neonates were reviewed. Spearman's rho rank correlation, receiver-operator characteristic(ROC) curve analysis, survival analysis and Cox's proportional hazard model were used for statistical analysis. RESULTS: There was a statistically significant correlation between latency period and AFI at admission. ROC curve analysis showed that AFI at admission had a significant predictive value in the prediction of latency period < 48 hours. Survival analysis demonstrated that AFI < 5.0 was strongly associated with the likelihood of shorter latency period, Cox's proportional hazard model indicated that AFI < 5.0 was a significant independent predictor for the occurrence of latency period < 48 hours even after adjustment of other independent variables. The patients with AFI <5.0 had a higher rate of cesarean section due to fetal distress than those with AFI > 5.0 but the incidence of chorioamnionitis was not significantly different between two groups. Comparing the perinatal mortality and neonatal morbidity including infectious morbidity between the neonates born to mothers with AFI <5.0 and those with AFI > 5.0, there was no significance after adjustment of gestational age at birth. CONCLUSION: AFI at admission has a significant correlation with latency period and predictive value in prediction of latency period in the patients with PPROM. AFI <5.0 is a independent predictor for the shorter latency period.

Minimal cleft lip has been defined as a cleft which does not extend over the vermilion. Minimal cleft lip has no specific classification and few methods for its correction. Based on our operative experience with secondary cleft lipnose deformities, we have developed principles of operation for minimal cleft lip: minimal incision, nostril and alar reconstruction, philtrum reconstruction. alignment of cupid's bow, and vermilial notching correction. Nine patients of minimal cleft lip were operated on from March 1992 to June 1998 in our department. Each partients was evaluated for lip and nose deformities presurgically: the nasal tip, columella, ala, scar, cupid's bow, lip pout and lip length. Every patients required a different technique for repair. Satisfactory results were obtained by treating the cleft following the principles.

OBJECTIVES: The purposes of this study were to determine the usefulness of transvaginal ultrasonographic assessment of the uterine cervix and to compare the diagnostic performance of ultrasonographic and digital examination of the cervix in predicting a successful induction of labor. STUDY DESIGN: One hundred-one singleton term pregnancies without ruptured membranes admitted for the labor induction were included in this study. Digital examination and transvaginal ultrasonography of the uterine cervix were performed at the time of admission. Cervical parameters evaluated included cervical length, presence of funneling, funnel length, and funnel width. Labor induction was underwent by prostaglandin E2 (PGE2) vaginal suppository and/or pitocin intravenous infusion. Outcome variable was a successful labor induction within 48 hours after beginning of the induction. RESULTS: The prevalence of induction failure was 10.9% (11/101). Receiver-operator characteristic (ROC) curve and multiple logistic regression analysis indicated a significant relationship between the successful induction of labor and cervical length <3.1 cm. The diagnositic indices of endocervical length was superior to those of Bishop's cervical score in predicting a successful induction of labor. In patients with cervical length <3.1 cm, the labor was induced successfully with fewer tablets of PGE2, less use of pitocin infusion, and shorter induction-delivery interval. CONCLUSION: Transvaginal ultrasonographical examination of the uterine cervix is more accurate than digital examination of the cervix in the prediction of a successful induction of labor in term gestation.

Occupational dermatosis is one of the most prevalent occupational disorders. However, the extent of the occupational dermatoses including incidences and prevalencies of each disease entity, and etiologic materials are not yet well stated in Korea. Authors reviewed the literatures on the statistic data and reports on the occupational dermatoses, and surveyed on the occupational dermatoses in two factories, and surveyed the physicians responsible to the occupational dermatoses with formed questionnaire. The results are as follows; 1. Among medical journals published since 1964, there were 31 articles on the occupational dermatoses. Of 31 articles, 18 were case reports and all others were review articles. Of 18 case reports, 9 were epidemiologic survey. The Workers' Periodic Health Examinations revealed that prevalence of the occupational dermatoses was highest(4.36 per 10,000 workers) in 1974, but number of the cases reported were decreased sharply since 1978 with some tendency to increase since 1987. There were 2,240 reported cases of occupational dermatoses between 1966 and 1992, which is 1.90% of all the reported occupational diseases. Skin infection and injuries due to chemicals were most frequent and there were 6 cases of skin cancer. 2. In an epidemiological survey on the dermatoses among 995 workers in a metal product manufacturing factory and 225 workers with acne, 130 workers with scar, 123 workers with deformity of toe nails. Scars, photosensitivity dermatitis, deformity of finger and toe nails, and acne were more prevalent in the metal product manufacturing factory(p<0.05). In the metal product manufacturing factory, workers treating organic solvents and oils had more dermatoses than those without treating the materials(p<0.05). On the skin patch performed on 16 workers in the metal product manufacturing factory, there were 8 cases of irritation dermatitis and 5 cases of contact dermatitis. Prevalence of contact dermatitis in the metal product manufacturing factory was 1.3%. 3. On the questionnaire survey, 34 dermatologists, 29 doctors of preventive medicine, and 22 family physician replied. The proportion of occupational etiology among all dermatoses assumed by the physicians were below 9%, and the most important occupational dermatosis in Korea was contact dermatitis. Main etiologic materials related to the occupational dermatosis were organic solvent, acid and alkali, and metals. The reason for the scarcity of report of occupational dermatoses were difficulty in diagnosis and physician's ignorance of the occupational etiology. They replied that to prevent the occupational dermatosis in the workplace, the use of protective devices was most important, and development of diagnostic criteria on the occupational dermatoses is urgent. Above results shows us that there is many workers with occupational dermatoses, but they are mostly unreported. Measures to prevent and manage the occupational dermatoses are not satisfactory at present. Hence, authors suggest measures for the precises diagnosis, report and prevention of the occupational dermatoses. a. Dernatikigustm orevebtuve physician, and industrial hygienist should work as a team to examine the high risk group and establish the preventive measures. b. Disease entities, diagnostic criteria of occupational dermatoses should be listed, criteria for the compensation and job fitting at recruitment should be established, and manual for the proper treatment and effective prevention of each occupational dermatosis should be developed. c. Patch test antigens against each occupational category should be developed and it should be available to any physicians responsible. d. To facilitate the diagnosis of occupational dermatoses by the doctors responsible for the Workers' Periodic Health Examination, development of standardized questionnaire, education on the techniques of the patch test, and cooperation with the dermatologist in diagnosis of occupational dermatoses is essential.

BACKGROUND: The purpose of this study was to determine whether cleansing the perineum and urethral meatus and using midstream urine affect the rate of bacterial contamination of urine specimens, and to determine the optimum urine collection method. We studied 41 asymptomatic healthy nursing school students. Women who were menstruating were not excluded from this study. METHOD: The first and midstream urinesamples were collected during consecutive urinationsby each woman. The first sample was not a clean-catch specimen, and the second one was a clean-catch specimen. Both specimens were studied by urinalysis and bacterial culture with standard methods. RESULTS: 41 women met the study criteria and 39 successfully completed the study. None of the urine cultures were positive. 68.3% of the non clean-catch first urine cultures, 53.7% of the non clean-catch midstream cultures, 33.3% of the first clean-catch urine culteres and 30.8% of the midstream clean-catch urine were found to be contaminated. There was a significant difference in the bacterial contamination rates between the first and midstream urine, and the clean-catch and non clean-catch urine(p=0.035, p=0.001 respectively). On urinalysis, 7.3% of the non clean-catch first urine, 7.3% of the non clean-catch midstream urine, 2.6% of the clean-catch first urine and 2.6% of clean-catch midstream urine were found to be above grade 2. CONCLUSIONS: According to our results, the bacterial contamination rate was the lowest in midstream and clean catch urine specimens. Threrfore it is recommended that the midstream clean-catch technique is the standard practice for collecting urine specimens for bacterial culture in women.

OBJECTIVES:
Hand-to-face contact (HFC) is the major route for the self-inoculation of pathogens. This study aimed to describe the characteristics of HFC behaviors among Korean adults during indoor activities.
METHODS:
Thirty participants were enrolled in the study, and 2 hours of videotaped data were collected from each participant. Contact data were recorded by examining the frequency and duration of HFC on the videos. Three training sessions were conducted for 2 readers to ensure the accuracy and reliability of videotape reading. Re-reading and verification of selected video data were performed to confirm intrapersonal and interpersonal validity. Contact exposure (CE) was determined by multiplying the contact frequency (CF) by the contact duration (CD) to quantify the intensity of contact during the observation time (2 hours).
RESULTS:
A total of 3,007 HFCs (1,305 mucous membrane contacts and 1,702 non-mucous membrane contacts) were observed for 60 person-hours. The median CF (person/2 hr) of the mucous membranes (eye; 4.0, nose; 15.5, mouth; 16.5) was 39.5/person and the median total CD was 177.0 sec/person. The median CE (frequency-duration/sec/person) was 5,795.0 (mouth: 1,356.0, nose: 600.0, eye: 57.5).
CONCLUSIONS
This study showed that the mouth and nose were the most frequent exposure sites for HFC. Avoiding habitual HFC, awareness of self-inoculation by HFC, and vigorous hand hygiene should be strengthened to prevent the spread of infections.
