1.Long term noise exposure of steel mill workers, hearing loss and blood pressure.
Korean Journal of Preventive Medicine 1991;24(4):496-506
A cross-sectional study was conducted to investigate the effect of long term noise exposure on blood pressure among steel mill workers. The workers participated in periodic medical examinations performed from August 27 to September 6 in 1990. Examined were 1,034 workers with high-level noise exposure(average 91.8+/-5.2 dB{AA)), and 390 workers with low-level noise exposure(average 75.2+/-4.6 dB(A)). No significant difference was found in systolic or diastolic blood pressure between the two exposure groups. Prevalence of hypertension (> or = 160 mmHg systolic or > or = 100 mmHg diastolic) was higher in a younger age group (< or = 40 years old) of high-level noise exposure than of low-level noise exposure. However, the difference was not statistically significant. Furthermore, in younger ages, prevalence of. hypertension appeared to be higher in the hearing loss group (> or = 25dB at 1000 Hz or > or = 40 dB at 4000 Hz in at least one ear) than in the normal hearing group. From multiple regression analysis, hearing loss, body mass index, age, alcohol and family history of hypertension were proven to be predictors of diastolic blood pressure (p<0.02). When regression was performed for each age group, hearing loss was a strong predictor of diastolic pressure in the younger age group (p<0.01).

OBJECTIVES: We investigated the effects of changes in obesity and life style factors, such as cigarette smoking, alcohol drinking, and exercise, on the changes in blood pressure and serum cholesterol among Korean men. METHODS: This study included 7,205 healthy male employees in the steel manufacturing industry. Each subject underwent health examination in 1994 and was re-examined in 1997. The study subjects were classified into four categories, according to changes in body mass index (BMI) (loss; stable; mild gain; severe gain), cigarette smoking (quitter; non-smoker; smoker continued; smoker started), alcohol drinking (quitter; non-drinker; drinker continued; drinker started) and exercise (more exercise; continuous regular exercise; continuous irregular or no exercise; less exercise), respectively. We evaluated the relationship between the categories of change in those independent variables and the changes in blood pressure and serum cholesterol, adjusted for BMI in 1994 and age by analysis of variance. RESULTS: The change in systolic blood pressure was positively associated with the changes in BMI (p<0.001) and drinking (p=0.001), but negatively with smoking (p=0.004), compared to the first category of each independent variables. The systolic blood pressure was significantly less increased in the continuous smoking group than quitter or non-smoker. The changes in diastolic blood pressure and serum cholesterol appeared to have statistically significant linear relationships only with the change in BMI. The change in exercise showed a marginal significance with diastolic blood pressure (p=0.088). CONCLUSIONS: These prospective data emphasize the importance of obesity as a determinant of the changes in blood pressure and serum cholesterol. In addition, the changes in smoking and drinking habits can affect systolic blood pressure.

This study was started for the purpose of providing the basic data for continous managment of kidney transplantation patients after discharge. This study was conducted on 180 patients who received renal transplants at three hospital ( B, M. P) pusan, korea.. The data collection was done for june 1. to August 31. 2002. General characteristics, renal transplantaton characteristics. physical characteristics, the level of compliance and the degree of educational demand were done by the number and percentage. the mean. standard deviation. The level of compliance and educational demand followed by the characteristics of general and kidney transplantation were analyzed by t-test and ANOVA. The result were as fallows: 1. Man was higher than woman such as 60.0%, Mean age was 42.5 years old. Average total duration of after operation was 5.5 years. 2. Cases of systolic blood pressure over 140mmHg were 10.0%, cases of diastolic blood pressure over 90mmHg were 22.8% and obesity factor in BMI was 15.6%. The person who daily water intake amount is 5000cc was 0,6%, the case that daily urine output is below 1000cc was 8.9%. and the case that urine output is zero was 0,6%. 3. The mean score of compliance was 77.47 point. The score in medication part was highest such as 4.67 point, that in stress situation was lowest such as 3,50 point. 4. The average score of educational demand was 154.02 point. and physical state part was 4.36 points highest. activation part was 3.48 points lowest. As a role of nurse Confirmation of compliance is very important encourage to make good through regular hospital visitation. point out the noncompliance part and then increase compliance of renal transplantation patient As well there will be maintain the normal kidney function to satisfy educational demand through continous education.

The disease Blount called tibia vara in 1937, is characterized by a failure of growth localized to the postero-medial part of the upper tibial metaphysis and epiphysis. The growth of the epiphyseal cartilage as well as that of the metaphysis and the epiphysis is disturbed, with consequent angulation of the tibia at the upper epiphysis which may, in untreated cases, produce bizarre deformities. Blount described two different types of tibia vara, an infantile type and an adolescent type. Presenting case is an adolescent type. He is 11 year old boy. The deformed tibia is corrected by osteotomy.

In general, soft tissue and bone tumors are diagnosed clinically by physical findings, laboratory data, and X-ray findings with only limited reliability, and a definite diagnosis must be supported by histopathological evidence. For this purpose, open biopsy routinely has been carried out, but there have been many disadvantages and sometimes followed by surgical complications. The present study was undertaken to compare the cytologic findings of soft tissue and bone lesions with the histological findings. The specimen were obtained by fine needle aspiration and Franklin-Silverman needle. For cytodiagnosis Stormby's cell block of aspirates were utilized. For histological diagnosis small tissue fragments obtained by the Franklin-Silvermans cutting needle were used. Then, the diagnostic accuracy of 3 different methods were compared, and the clinical applicability of those methods as adjunctive diagnostic procedures in the diagnosis of the soft tissue and bone tumors were assessed. The results obtained were as follows: l. In 15 out of the 20 cases (75%) in which clinically and roentgenologically the soft tissue and bone tumors were suspected, sufficient material was aspirated to enable detailed cytological diagnosis possible by fine needle aspiration. ln 13 out of the 15 cases, diagnosis could be made by cytologic findings, which was similar to histologic findings of tissue obtained by Franklin-Silverman needle. 2. In 6 out of the 20 cases, sufficient tissue fluid for cell block preparation were obtained from the tumor tissues. In 5 cases, cytologic findings of cell blocks were consistent with that ot the tissue obtained by Silverman needle. But in one case malignancy was susupected by cytodiagnostic method, and definite diagnosis could not be made. Finally the lesion was found to be malignant schwannoma through the histological study of tissue specimen obtained by Franklin-Silverman needle biopsy. 3. In 19 out of the 20 cases, diagnosis could be made by Franklin-Silverman needle biopsy. 4. Diagnostic accuracy of the lesions by clinical and roentgenological method was 75%, which overall diagnostic accuracy of 3 methods were 86.7% in aspiration cytology, 83.3% in cytodiagosis of cell block and 95% of histodiagnosis of tissue specimen obtained by Franklin-Silverman needle. Through this study it is found that cytodiagnostic method of aspirates and histodiagnosis of the small tissue specimen by Franklin-Silverman needle are very useful adjunctive methods in enhancing the diagnostic accuracy of the soft tissue and bone lesion prior to open biopsy trial.

In this study, author tried to clarify the chronological and histological change of the growing spine after posterior cement fixation in dogs. The material used for the study consisted of 24 male mongrel dogs, aged 8 weeks. Lumbar spines, from 3rd to 5th were fixed posteriorly with bone cement (Zimmer Co. U.S.A.). After posterior spinai fixation with bone cement, there dogs at a time were sacrificed every 4 weeks up to 32 weeks, and histologic changes of intervertebral disc, growth plate and the vertebral bodies were observed after hematoxylin & eosin stainning with light microscope. The results obtained were as follows: 1. Thinning of the growth plate and distortion of the cartilage columns developed gradually after posterior cement fixation of the spine, but premature closure of the growth plate did not develop and the growth of the vertebral body continued till 32 weeks after operation. 2. Intervertebral disc thinned posteriorly and widened anteriorly without any changes in subchondral cortices, though there is some bony atrophy in the body which is represented by the thinning and coarseness of bony spicules. 3. At 16 weeks the cartilage layer of the vertebral end plate became thinner, and at 32 weeks there were profound degenerative changes in the cartilages. 4. After fixation of the spine, the nucleus pulposus gradually degraded and was replaced by fibrous tissues, and began to adhere to the vertebral end plate at 24 weeks and completely adhered to it at 32 weeks after fixation. 5. The direction of the horizontally arranged annulus fibrosus began to derange from 24 weeks after fixation, and at 32 weeks all the fibers of the annulus fibrosus were vertically arranged completely. Through this study it is found that posterior spinal fixation with bone cement affects growths of the vertebral growth plate, and end plate slightly, but there were no cessation of cartilaginous growth which might later cause the vertebral deformity. Also it is clarified that posterior fixation of e spine with cement develops noticeable degenerative changes in the intervertebrai disc and thereby develops the lordotic curve of the cemented segment of the spine.

Since Palmer's introduction of the torn medial collateral ligament, many clinical and anatomical studies were performed. But any reconstructive procedure of the medial collateral ligament of the knee known to us, has not solved the problem completely yet. The purpose of present study is to describe a technique of reconstruction, socalled Tatsuzawa's tenodesis surgery of transposed semitendinosus tendon, and is to report the clinical results of 45 cases treated by his procedure between April 1976 and June 1981. In addition, significance of the procerdure was compared with the result of primary closure group of the torn ligament. Tatsuzawa's procedure consists of reinforcement surgery of the repaired or unrepaired torn medial collateral ligament with forwardly transposed semitendinosus. The semitendinosus tendon was brought forward to lie adjacent to deep layer of the medial collateral ligament. The transposed part of the tendon was sutured throughout its length to the medial collateral ligament and to the medial aspect of the tibia and femoral condyle. Because the direction of transposed tendon as similar to the direction of fibers of medial collateral ligament, the procedure was very simple and anatomical one, and had some functional advantages. In this series some old cases are treated only with tendon reinforcement operation without repairing the laxed torn ligament. The results of the surgery were evaluated by the Asais modification of the Feltons evaluation criteria. Results obtained were as follows: 1. In semitendinosus tenodesis with or without primary repair of the torn ligament, satisfactory results were obtained (excellent and good) in 33 cases (73.3%). But in 20 cases of the primary repair group, the satisfactory results were obtained in 11 cases (55%). More satisfactory results were obtained with the semitendinosus tendon reinforcement operation of the torn ligament than only with primary repair. 2. In 29 cases with fresh injury of the medial collateral ligament in which the primary repair together with the tendon reinforcement procedure was performed, satisfactory (excellent and good) results were obtained in 72.4% (21 cases), and in 16 untreated old cases in which only the tendon reinforcement procedure were done, satisfactory results were obtained in 75%. 3. In 5 cases having medial collateral and anterior cruciate ligaments tear, excellent results were obtained in 3. This explains that semitendinosus tendon reinforcement procedure is the key one of the reconstructive operative procedures. It is thought that the procedure is also effective for the anterior cruciate tear to provide the anterior instability.
