The purpose of this study was to assess the morbidity pattern of urban residents in the poor area by health screening for the community diagnosis. The items of health screening were history taking and physical examination by medical doctor and hearing test, check blood pressure, test for hematocrit, liver function (sGOT, sGPT), urine sugar and protein, and chest X-ray. The examinee in health screening were 437 persons and they occupied 16.9% of total residents in the poor area. Male examinee were 129 persons (9.9% of total residents) and female examinee were 308 persons (23.9% of total residents). Age group of above sixty years old, 42.0% of total residents in the poor area were participated, but only 5.9% were participated in age group of 10 to 19 years old. Among the 437 examinee, 191 persons (43.7%) had one or more abnormal findings in health screening. In male 38.7% had abnormal findings, and somewhat lower than that of female (45.8%). Age group of above sixty years had most high rate of abnormal findings (69.8%), in contrast to age group of 10 to 19 years old (10.9%). Diseases of the digestive system was the most common and which occupies 23.7% of total abnormal findings. And diseases of the circulatory system occupied 19.7%. Low hematocrit (14.6% of total participants of 437 persons) occupies the most common abnormal findings for screening test (hematocrit, blood pressure, hearing test, sGOT/sGPT, urine protein and urine sugar, chest X-ray) and high blood pressure (10.1%) occupied second, third; hearing impairment (5.5%), fourth; abnormal liver function (4.1%), fifth; sugar in urine (2.3%), sixth; protein in urine (1.4%) and lastly abnormal chest X-ray (0.9%). The positive rate of abnormal findings in health screening was very high compared with morbidity rate by health interview. It is supposed that some portion of this high rate is by selection bias in examinee in health screening specially high participating rate in older age, and the other portion is due to the low socioeconomic status and bad environment of the residents of the poor area. These findings will be good information for the research and development of health care system in the urban poor area.

A household survey was conducted to compare the patterns of morbidity and medical care utilization between medical aid beneficiaries and medical insurance beneficiaries. The study population included 285 medical aid beneficiaries that were completely surveyed and 386 medical insurance beneficiaries selected by simple random sampling from a Dong (Township) in Taegu. Well-trained surveyors mainly interviewed housewives with a structured questionnaire. The morbidity rates of acute illness during the 15-day period, were 63 per 1,000 medical aid beneficiaries and 62 per 1,000 medical insurance beneficiaries. The rates for chronic illness were 123 per 1,000 medical beneficiaries and 73 per 1,000 medical insurance beneficiaries. The most common type of acute illness in medical aid and medical insurance beneficiaries was respiratory disease in medical aid beneficiaries, musculoskeletal disease was most common, but in medical insurance beneficiaries, gastrointestinal disease was most common. The mean duration of acute illness of medical aid beneficiaries was 3.8 days and that of medical insurance beneficiaries was 6.8 days. During the one year period, mean duration of medical aid beneficiaries chronic illnesses was 11.5 months which was almost twice as long compared to medical insurance beneficiaries. Pharmacy was most preferable facility among the acute illness patient in medical aid beneficiaries, but acute cases of medical insurance beneficiaries visited the clinic most commonly. Chronic cases of both groups visited the clinic most frequently. There were some findings suggesting that much unmet need existed among the medical aid beneficiaries. In acute cases, the average number of days of medical aid users utilized medical facilities was less than medical insurance users. On the other hand, the length of medical care utilization of chronic cases was reversed. Geographical accessibility was the most important factors in utilization of medical facilities. Almost half of the study population answered the questions about source of funds on medical security correctly. Most respondents considered that the objective of medical security was affordability. The chief complaint on hospital utilization was the complicated administrative procedures. These findings suggest that there were some problems in the medical aid system, especially in the referral system.

To determine the incidence rate of accidents and its associated factors, a prospective survey was carried out in a rural area of a total of 1,360 residents for 1 year from January 1 to December 31, 1988 in Shin-am Ri, Jungdong Myun, Sangju Kun, Kyeongpook Province. Data for accidents were collected by the community health practitioner who is working at Primary Health Post in Shin-am Ri. A total number of accident cases was 85 among 1,360 persons during one year study period, and annual incidence rate was 62.5 per 1,000 persons. The highest incidence rate of accident was observed in the age group of 30-39 was 179.8. The incidence rate of accident in male was 86.5 which was about 2 times that in female. In male, the highest incidence rate was seen in 30-39 age group and in female, 60-69 age group. The highest incidence rate of accident was observed in spring (29.4%) and summer (29.4%), and the lowest in fall (17.7%). The highest incidence rate of accident was observed in Friday (24.5%) by day of week, and between 9 a.m. to 12 a.m. by time zone. The most frequent use of medical facilities was Primary Health Post (51.8%) and the next was clinic (38.8%). Mean duration of treatment was 9.8 days. The accident occurred in the room and kitchen (23.5%), in the yard and barn (23.5%), on the road (22.4%), and in the rice field and dry field (20.0%). The causes of accident were motor vehicle accident (20.0%), piercing or cutting (20.0%), collision or fighting (12.9%), and poisoning (11.8%) in order of frequency. The most common type of injury was open wound which was 43.5%. The most common tool of accident was farm machine which was 23.5%. The most common injured part of body was extremity 55.3%.

It is becoming increasingly apparent that periodontitis consists of mixture of diseases, most of which respond favorably to traditional mechanical therapy. Among these variants of the disease, some appear to be associated with unusual microbial infections and defective host defenses. Many of these fail to respond to conventional treatment. The recognition that some forms of periodontitis are refractory to standard periodontal therapy has given rise to a new classification of peridontitis. A series of 1692 subgingival microbial samples sent to a diagnostic microbiology laboratory included 738 samples that could be identified as compatible with a clinical diagnosis of refractory or recurrent periodontitis. In descending order of prevalence the associated microbiota included Bacteroides forsythus(85%),Fusobacterium species(78%), Spirochetes(67%), Campylobacter rectus(64%), Porphyromonas gingivalis(59%), Peptostreptococcus micros(58%), motile rods(46%), Prevotella intermedia(33%), Eikenella corrodens(13%), Capnocytophaga species(12%), and Actinobacillus actinomycetemcomitans(6%). Antibiotic resistance to tetracycline, penicillin G, or metronidazole was particularly noticeable for Fusobacterium species, Capnocytophaga species, and Actinobacillus actinomycetemcomitans. It was largely absent for Campylobacter rectus. No antibiotic data were obtained for Porphyromonas gingivalis or Bacteroides forsythus, as these species were detected by immunofluorescence. The results indicate that a substantial number of microorganisms associated with refractory periodontitis are variably resistant to commonly-used antibiotics. Diagnostic microbiology must be considered an essential adjunct to the therapist faced with periodontal lesions refractory to conventional treatment.

BACKGROUND: Neuromuscular ultrasound has emerged over the last decade as a useful tool for diagnosing peripheral neuropathy. Because nerve enlargement is the most important diagnostic marker of an abnormal nerve, quantification of nerve size is essential. METHODS: We included 80 healthy volunteers aged 21-60 years. The nerve cross-sectional area (CSA) was measured in all participants at the following common compressive sites: bilateral median nerve at the carpal tunnel and forearm, ulnar nerve at the wrist and medial epicondyle, radial nerve at the spiral groove, peroneal nerve at the fibular head and popliteal fossa, and tibial nerve at the popliteal fossa. Anatomical variants were also evaluated, including a bifid median nerve and persistent median artery. RESULTS: The CSAs were 9.58+/-1.55, 6.87+/-1.61, 4.72+/-0.91, 6.64+/-1.33, 6.48+/-1.68, 12.35+/-3.55, and 26.98+/-6.92 mm2 (mean+/-SD) for the median nerve at the carpal tunnel and forearm, ulnar nerve at the wrist and medial epicondyle, radial nerve at the spiral groove, peroneal nerve at the fibular head, and tibial nerve at the popliteal fossa, respectively. The nerve CSA was significantly larger in men than in women and was correlated with body mass index, weight, and height. A bifid median nerve and persistent median artery were seen in 12 (7.5%) and 4 (2.5%) of 160 hands, respectively. CONCLUSIONS: The information produced in this study can serve as reference data when evaluating these nerve sites using ultrasound.

OBJECTIVE: In this study, we focused on estimating the burden of premature death in Korea caused by smoking using the YLL (years of life lost due to premature death) measurement. METHODS: First, we determined parameters: such as age-specific standard life expectancy, age on death, sex, and cause of death by analyzing the national death certificate data and life table collected during 1997. These were provided by the National Statistical Office. Secondly, we estimated the age group- specific years of life lost due to premature death by employing the standard expected years of life lost (SEYLL) measurement. Thirdly, the burden of premature death caused by smoking was estimated using the YLLs measurement which was developed by the global burden of disease study group. Fourthly, We calculated the risk related to smoking using the population attributable risk. RESULTS: The following results were obtained in this study:1) Premature death that is attributable to smoking in males could be prevented in 60.9% (513,582 person-year) by non-smoking.2) The burden of premature death by smoking for female was prevented to 17.7% (513,582 person-year) by non-smoking. CONCLUSION: We found that the YLL method employed in this study was appropriate in quantifying the burden of premature death. This provides a rational basis for planning a national health policy regarding premature deaths caused by smoking and other related risk factors.

BACKGROUND: This study was performed to compare efficiency of embryonic stem (ES) cell-derived dopaminergic (DA) neurons from E12 mesencephalic neuronal-precursor derived DA neuron, and to assess the value of these neurons as a donor cells to transplant in Parkinson's disease. METHODS: ES cell-derived DA neurons from E12 mesencephalic neuronal-precursor derived DA neuron were transplanted in Parkinsonian rats and analyzed TH immunoreactivity and apomorphin-induced rotation test. RESULTS: Transplanting of ES cell derived DA neurons into the rat striatum caused gradual increase of expression of tyrosine hydroxylase (TH) immunoreactivity 6 weeks after transplant in host striatum. Rotation behavior was gradually on the decrease, 6 weeks after transplant of ES cell derived DA neurons. In case of E12 mesencephalic precursor derived DA neurons, the TH immunoreactivity expressed 6 weeks after transplant in striatum, and the behavioral restoration of DA-mediated motor asymmetry sustained gradually. However, transplanted ES cell derived DA neurons appeared in wide regions among the needle tract with a relatively high density of TH immunoreactivity in comparison to the E12 mesencephalic precursor DA neurons, and graft volume of ES cell derived DA neurons were larger than E12 mesencephalic precursor derived DA neuron. In addition, both cells did not appear cancerous change after transplantation. CONCLUSIONS: These results suggest that ES cell is more efficient than E12 mesencephalic precursor derived dopaminergic neuron and will supply efficient donor cells for transplantation in Parkinson's disease.

The purpose of the study was to assess the morbidity pattern and the medical care utilization behavior of urban residents in the poor area. The study population included 2,591 family members of 677 households in the poor area of Daemyong 8 Dong, Nam-Gu, Taegu and 2,686 family members of 688 households, near the poor area in the same Dong, were interviewed as a control group. On this study the household interview method was applied. Well-trained interviewers visited every household in the designated area and individually interviewed heads of households or housewives for general information, morbidity condition, and medical care utilization with a structured questionnaire. Individuals were interviewed from 1 to 30 December 1988. The major results were summarized as follow: The proportion of the people below 5 years of age was 4.2% of the total study population and 5.5% were above 65 years of age in the poor area. This was slightly higher than in the control area. The average monthly income of a household in the poor area was 403,000 won versus 529,000 won in the control area. Fifty-eight percent of the residents in the poor area and sixty-one percent in the control area were medical security beneficiaries, but the proportion of medical aid beneficiaries was 7.8% in the poor area and 4.6% in the control area. The 15-day period morbidity rate of acute illnesses was 57.1 per 1,000 in the poor area and 24.2 per 1,000 in the control area. Respiratory disease is the most common acute illness in both areas. The most frequently utilized medical facility was the pharmacy among the patients with acute illnesses in the poor area. Among them 58.1% visited pharmacy initially while 38.4% of the patients in the control area visited a clinic. Among persons with illnesses during the 15 days, 8.8% in the poor area and 4.6% in the control area did not seek any medical facility. Mean duration of utilization of medical facilities was 3.5 days in the poor area and 3.3 days in the control area. Initially of the medical facilities in Daemyong 8 Dong, The pharmacy in the poor area and the clinic in the control area were most commonly utilized. The most common reason for visiting the hospital was 'regular customers' in the poor area and 'geographical accessibility' in the control area. The one year period morbidity rate of chronic illness in the poor area was 83.0 per 1,000 population and 28.0 per 1,000 in the control area. Disease of nervous system was the most common chronic illness in the poor area while cardiovascular disease in male and gastrointestinal disease in female were most prevalent in the control area. The most frequently utilized medical facility was the pharmacy among the patients with chronic illnesses in the poor area. Among them 24.2% visited the pharmacy initially while 34.7% of the patients in the control area visited the out-patient department of the hospital within a 15-day period. Among the patients with chronic illnesses 34.9% in the poor area and 16.0% in the control area did not seek any medical facility. Mean duration of utilization of medical facilities was 9.2 days in the poor area and 9.9 days in the control area within a 15-day period. Initially of the medical facilities in Daemyong 8 Dong, the pharmacy in the poor area and the hospital in the control area were most commonly utilized. The most common reason for visiting the hospital, clinic, health center or pharmacy in the poor area was 'geographical accessibility' while the reason for visiting herb clinic was 'good result' and 'reputation' in both areas.

The purpose of this study was to evaluate various methods of decontamination of ultrasonic scalers, high-speed handpieces and air-water syringes in dental equipments. Eimination of possible sources of microbial infection in dental operatories should be of primary importance. Microbial contamination levels of high speed handpieces, air-water syringes and ultrasonic scalers of 11 dental units in Seoul National University Hospital were evaluated after flushing the lines, alcohol sponge rubbing, or soaking in 0.1% chlorhexidine for 1,3 and 5 minutes. The result suggests that flushing the lines or soaking the tips in 0.1% chlorhexidine before use of the water systems may reduce the microbial levels. Soaking in 0.1% chlorhexidine for 5 minutes was most effective in reducing bacterial contamination.
