This study was carried out to evaluate the relations among working environments, health behaviors and satisfaction with their duty in a group of 200 ship-repair workers in the ROK navy. The results were as following; Age of workers was 40 years and over(83%) and working duration was 10 years and over (71.5%). Most of them were married and had studied beyond high school. The 69.5% of workers satisfied with their job, whereas. about 59.5% of workers had satisfaction with their working condition. There were current drinkers, 78.5%, current exercising workers, 43.5%, obese workers, 28.0%, and salted food intakers, 18.5% in the workers. The major harmful environmental factors in the ship-repair workplace are noise, vibration, dust and chemicals. Most of workers are exposed to above harmful factors and complained about exposure of noise and dust. The consumption of cigarette or alcohol in people who exposed to noise was much higher than in people who did not, but the difference was not statistically significant. Prevalence of obesity and hypertension were not significantly different between the exposure with noise and dust. Noise or dust exposure was significant relation to satisfaction with their duty and working condition. The affective factors for satisfaction with their duty were people who worked for 10 years or more(OR= 4.53), exercisers(OR=4.78) and dust(OR=3.05) in Logistic regression analysis.

In the past years skin grafts, local flaps and free flaps have been used in reconstructing skin or sift tissue defects and deformities of the face where primary closure is not feasible. A number of local flaps have been used for reconstruction of facial defects and deformities, but the size of a defect that could be treated in such a way was restricted and the donor site deformity was another problem of local flaps. Introduction of the tissue expansion technique has made it possible to cover even wider defects with neighboring skin and advantageous in facial reconstruction in that such defects can be resurfaced with skin of similar color, texture and thickness, a match superior to that of skin obtained elsewhere. We used tissue expanders in reconstructing defects and deformities of the face(post-burn scar ; 17cases, post-traumatic scar ; 7cases, congenital nevus ; 3cases, total 27cases) from Mar. 1990 to Sep. 1996. We used or croissant type tissue expander for the reconstruction of small-sized scar on medial cheek and to use rectangular type expander for large-sized scar on lateral cheek. Ports are placed under the scar or scalp. Expansion period ranged from 28days to 97days (mean 7weeks) and overinflation (mean 170%) was done. And Various methods are used for prevention of complication. We have made anchoring sutures of the remained capsule to the underlying periosteum for prevention of ectropion. We have got satisfactory results from that aesthetically and functionally, so report the results with a review of the current literature.

This study was performed to evaluate the effect of hydrogen peroxide-producing Lactobacillus acidophilus V-20 on the replication of periodontal pathogens, Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis. When A. actinomycetemcomitans and P. gingivalis were incubated alone and in the combination with L. acidophilus V-20, the viable cell numbers of A. actinomycetemcomitans and P.gingivalis were compared between those cultures. The effect of S. mutans, E. durans, and L. lactis on the replication of A. actinomycetemcomitans and P. gingivalis was also evaluated. The change of periodontal indexes(probine depth, gingival index, GCF volume) and the viable cell numbers of A. actinomycetemcomitans and black pigmented bacteroides in subgingival plaque sample were evaluated following gargling of fermented milk made from L.acidophilus V-20 for 1 month on patients with periodontal disease in maintenance phase. In the mixed culture of L. acidophilus V-20 and A. actinomycetemcomitans or P. gingivalis, the replication of A. actinomycetemcomitans or P. gingivalis was completely inhibited. But in the mixed culture of P. gingivalis and hydrogen peroxide-nonproducing Lactobacillus casei, the viable cell numbers of P. gingivalis was not decreased when compared with the numbers in the mixed culture of P. gingivalis and L. acidophilus V-20. In the mixed culture of A. actinomycetemcomitans and S. mutans, E. durans, or L. lactis, the viable cell number of A. actinomycetemcomitans was not almost changed when compared with the numbers in the culture of A. actinomycetemcomitans alone. And in the mixed culture of P. gingivalis and E. durans or L. lactis, the viable cell numbers of P. gingivalis was not almost changed compared with the counts in the culture of P. gingivalis alone. But the replication of P. gingivalis was completely inhibited in the mixed culture of P. gingivalis and S. mutans. When the change of periodontal indexes following gargling of fermented milk was compared with baseline, probing depth and gingival index were not changed, but GCF volume was significantly decreased(p<0.05). And when the viable cell numbers of microorganisms in subgingival plaque sample were compared with baseline, total viable cell number was almost unchanged and the viable cell numbers of A. actinomycetemcomitans and black pigmented bacteroides were significantly decreased(p<0.05). These results suggest that L. acidophilus V-20 inhibit the replication of A. actinomycetemcomitans and black pigmented bacteroides by the formation of hydrogen peroxide.

연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.

Objectives: The aim was to confirm the stem cell-like properties of the dental pulp stromal cells and to evaluate the morphologic changes during in vitro chondrogenesis. Materials and Methods: Stromal cells were outgrown from the dental pulp tissue of the premolars. Surface markers were investigated and cell proliferation rate was compared to other mesenchymal stem cells. Multipotency of the pulp cells was confirmed by inducing osteogenesis, adipogenesis and chondrogenesis. The morphologic changes in the chondrogenic pellet during the 21 day of induction were evaluated under light microscope and transmission electron microscope. TUNEL assay was used to evaluate apoptosis within the chondrogenic pellets. Results: Pulp cells were CD90, 105 positive and CD31, 34 negative. They showed similar proliferation rate to other stem cells. Pulp cells differentiated to osteogenic, adipogenic and chondrogenic tissues. During chondrogenesis, 3-dimensional pellet was created with multi-layers, hypertrophic chondrocyte-like cells and cartilage-like extracellular matrix. However, cell morphology became irregular and apoptotic cells were increased after 7 day of chondrogenic induction. Conclusions: Pulp cells indicated mesenchymal stem cell-like characteristics. During the in vitro chondrogenesis, cellular activity was superior during the earlier phase (within 7 day) of differentiation.

Transcatheter arterial chemoembolization (TACE) has become an effective alternative treatment strategy for patients with inoperable hepatocellular carcinoma (HCC). Although TACE is relatively safe, acute respiratory distress syndrome associated with pulmonary lipiodol embolism is a rare and potentially fatal complication. We report a rare case of acute respiratory distress syndrome after TACE for inoperable HCC. A 75-year-old man, with huge HCC in right lobe, was treated by TACE for the first time. Seven hours after uneventful TACE procedure, he felt dyspneic and his oxygen saturation recorded by pulse oximetry (SpO2) fell to 80% despite of applying non-rebreathing mask. He underwent mechanical ventilation with a protective ventilatory strategy. We experienced a case of acute respiratory distress syndrome after TACE for HCC.

소규모사업장 보건관리기술지원사업 지원여부에 따른 사업장내 의사소통 비교

목적: 소규모사업장 보건관리기술지원사업 지원여부에 따라 사업장내 위험의사소통채널이 마련되었는지와 이 채널이 기능을 하는지, 그리고 의사소통채널마련과 사업장내 위험의사소통 활성화의 기본적이고 중요한 배경이 되는 사업주의 산업보건에 대한 관심이 차이가 있는지에 대해 살펴보고자 하였다. 방법: 서울, 안산, 대전, 광주, 포항 지역에서 보건관리기술지원사업을 받은 사업장과 받지 않은 사업장을 대상으로 비례층화무작위표본추출법을 사용하여 추출한 후 1991년 12월 6일부터 10일간 우편설문조사를 실시하였다. 설문대상은 각 사업장의 남녀 각 1명, 보건업무담당자, 사업주였으며, 설문내용은 사업장 및 응답자의 일반적 특성 및 사업장내 위험의사소통이었다. 설문에 응답이 온 463개 사업장의 자료를 자료처리하여 총 228개 사업장(단해년도지원 사업장 189개, 연속2년지원 사업장 13개, 비지원사업장 26개)을 대상으로 분석하였다. 결과: 사업장내 의사소통에 대한 단변량분석에서는 보건업무 담당자의 선정여부만이 통계적으로 유의한 차이가 있었다. 소규모사업장 보건관리기술지원사업을 지원받지 않은 사업장과 지원받은 사업장의 사업장내 위험의사소통을 비교하기 위한 로지스틱회귀분석 결과, 모든 항목에서 통계적으로는 유의한 차이를 보여주지 않았다. 그러나 사업주의 관심(OR ; 1.63, 95% CI ; 0.38~7.01)과 보건업무담당자의 선정(OR ; 3.67, 95% CI ; 1.00~13.44) 및 결정권한(OR ; 1.48, 95% CI ; 0.25~8.91), 사업주의 산업보건문제 소통(OR ; 3.07, 95% CI ; 0.81~11.71), 보건업무담당자의 정보요청경험(OR; 4.48, 95% CI ; 0.97~20.57)에서는 지원받지 않은 사업장에 비해 지원받은 사업장에서 교차비가 증가하는 양상을 보여주었다. 반면 노동자의 산업보건문제 소통가능성여부는 오히려 교차비가 0.53(95% CI ; 0.11~2.44)로 감소하는 경향을 보여주었다. 결론: 소규모사업장 보건관리기술지원사업을 의사소통의 측면에서 평가해보면, 사업주나 보건업무담당자에게는 다소 효과가 있었지만 노동자가 지속적으로 참여할 수 있도록 의사소통문화를 바꾸어내는 데에는 한계가 있었다. 개선을 위해서는 노동자 중심의 접근 프로그램의 개발 및 시행이 시급하다 할 수 있다. Objectives :This study was to evaluate the effectiveness of the government-funded subsidized occupational health program for small-scale enterprises(GSOHP_SSE) by occupational health com-munication in workplace. Methods : We sampled the 1,835 enterprises of study by proportional stratified random sampling among industries of supported and not supported by GSOHP_SSE in Seoul, Ansan, Daejeon, Kwang-joo and Pohang. Information on the general characteristics of enterprises and respondants and occupational health communication in the workplace was collected on self-reported questionnaires by post-survey between December 6 and 15 in 2001. We received answers from 463 enterprises and analyzed 228 enterprises through data-cleaning by logistic regression to evaluate effectiveness of GSOHP-SSE about occupational health communication in the workplace. Results : By multiple logistic regression analysis, GSOHP_SSE turned out not to be statistically significant factor in all dependent variables about occupational health communication in the work-place. The concern of owner(odds ratio (below OR) ; 1.63, 95% confidence interval(below 95% CI) ; 0.38-7.01), formation(OR ; 3.67, 95% CI ; 1.00-13.44) and empowerment(OR ; 1.48, 95% CI ; 0.25-8.91) of health manager, request about occupational health problem of health manager(OR ;4.48, 95% CI ; 0.97-20.57) and occupational health communication of owner (OR ; 3.07, 95% CI ; 0.81-11.71) had the trend increasing OR in the industries supported GS-OHP_SSE relative to the industries not supported. But in recognition of possibility on occupational health communication of laborers, OR of GSOHP_SSE was decreased in 0.53(95% CI ; 0.11-2.44). Conclusions: This study found that the GSOHP_SSE was some effective to the side of employer and health manager, but had a limitation about change of communication culture useful to the laborers. We suggested the laborer-centered health training programs or the empowerment-based health training programs for effective occupational health management in the workplace.
