Low back pain patients an controls of shipyard workers were surveyed between June 1995 and september 1995 to identify risk factors of industrial low back pain. The patients were 17 male workers who had got medical treatment for over 3 days because of industrial back pain controls were 51 male workers who had not have musculoskeletal disorder for one year before the survey. By univariate analysis, the workers who did overtime work 4 times or more for the last 2 weeks showed odds ratio of 3.67 on low back pain with the workers who did less overtime work. Carrying heavy materials was also associated with the low back pain and the odds ratio increased with the increase of carrying weight. work space and work posture were not associated with the low back pain significantly. The welder had higher odds ratio than the other workers on low back pain. The duration of employment and job satisfaction did not affect the risk of low back pain. Multiple logistic regression analysis showed that frequency of overtime work for the last 2 weeks and carrying heavy materials among the risk factors were associated significantly with the low back pain. We found that important risk factors of low back pain of shipyard workers are work intensity factors such as overtime work and carrying heavy weight.

A 52-year-old woman was admitted with a palpable mass on the abdominal wall. This tumor had developed at the same site of a previously resected dermatofibrosarcoma protuberans. The biopsy specimen from the recurrent tumor revealed malignant fibrous histiocytoma. Immunohistochemistry with anti-CD34 antibody revealed diffuse linear positivity on the tumor cells of dermatofibrosarcoma protuberans and negativity on malignant fibrous histiocytoma. Anti CD34 antibody was valuable for a differential diagnosis of these two lesions.

Adenoid cystic carcinoma (ACC) of the breast is an uncommon carcinoma accounting for less than 1% of the breast carcinoma. This type of carcinoma has a distinctive histology, such as cylindromatous, cribriform, glandlike space and solid pattern in the variable proportion. Prognosis is favorable with rare recurrence or metastasis and the guideline for therapy is not well established. We experienced a case of ACC of right breast in the 48 year-old woman. Cytologically, it showed numerous three-dimensional, well outlined cell clusters with central core of homogeneous, eosinophilic material. The mass was well demarcated, firm and measured 2.5 2.5 2 cm. Cut surface was yellowish white and granular with focal necrosis. Histologically, the tumor was composed of cylindromatous, adenoid and solid area with marked cellular atypia. Focal invasion was identified in the adipose tissue around the tumor. Histologic and nuclear grade was III by Kleer's grade. Nodal metastasis was not found.

This study was performed for the comparison of the therapeutic efficiency between 6-month (2tHER/4HER) and 9-month (9HER) short-course chemotherapy under the programe conditions for pulmonary tuberculosis in terms of sputum AFB negative conversion rate, remedial interruption rate and cost effectiveness analysis. Two hundreds and ninty three patients treated with 9HER and 641 treated with 2HERZ/4HER had been discharged from 22 health centers in Seoul from May 1, 1993 to April 30, 1994. Seven hundreds and seventeen was subsequently analysed excluding 217 patients due to remedial interruption. The results: 1. Bacteriological negative conversion rate in 9HER regimen and 2HERZ/4HER regimen was 97.8% and 96.4% respectively (p>0.05). But the early treatment period, negative conversion rate in 2HERZ/4HER regimen was very higher than in 9HER regimen(p<0.01). 2. Remedial interruption rate for 9HER regimen and 2HERZ/4HER regimen was 34.1% and 13.6% respectively. The primary reason for the interruption was transfering to other clinics and this interruption was high within 3months. 3. Cost effectiveness for 2HERZ/4HER regimen was higher than 9HER regimen. The difference cost effectiveness ratio was 2.33 at the first sputum test and 1.69 at the last sputum test.

The time course of recovery in vestibular neuritis varies between individuals. The aim of this study was to identify the predictors for the early or late recovery of vestibular neuritis. The inclusion criteria were patients 1) who had an acute onset of vertigo lasting at least 24 hours, 2) with a horizontal-torsional unidirectional spontaneous nystagmus, and 3) with a canal paresis of 20% or more on the bithermal caloric tests. The primary endpoint for this study was an early or late recovery of vestibular neuritis as a dependent variable. A functional level scale was used to define the late recovery (5 or more points) at seven days after the symptom onset. The secondary endpoint was the duration of hospitalization. One hundred twenty eight patients met the inclusion criteria for this study, and among them, 71 patients had an early recovery. Multiple logistic regression analysis showed that diabetes mellitus was the only independent significant variable for the prediction of a late recovery of vestibular neuritis. In addition, the diabetes mellitus was a predicting variable for long duration of hospitalization. Diabetes mellitus was a predictor for a late recovery of vestibular neuritis.

Purpose: The purpose of this descriptive study was to identify factors influencing pulmonary tuberculosis patients’ self-care behaviors. Methods: The patients were 125 adults over the age of 19 who were diagnosed with pulmonary tuberculosis, receiving care at the National tuberculosis hospital. The survey questions measured family support, multidimensional scale of perceived social support (MSPSS), stigma and self-care behaviors. Results: The average score for self-care behaviors was 3.91, ranging from 2.22 to 5.00. There was a significant positive correlation between self-care behaviors and support system. There was a significant negative correlation between self-care behaviors and stigma. The significant variables influencing self-care behaviors were family support (β = .33, p< .001), smoking (β= -.23, p= .002), age (β= .22, p= .005) and experience of stopping treatment (β= -.17, p= .040). These factors explain 36% of pulmonary tuberculosis patients’ self-care behaviors. Conclusion Family support is very important to improve selfcare for tuberculosis patients. However, those in their fifties, men, and those who do not have a job and have underlying diseases have low family support, so they need active support at the national level. The study results suggest that a educational and nursing programs must be designed to reduce stigma and promote support system in order to enhance self-care behaviors.

The expression of the nuclear phosphoprotein p53, a product of tumor suppressor gene, has been noted in a number of human tumors as a tumor suppressor. nm23 is a gene associated with low tumor metastatic potential and has been proposed to be a metastasis suppressor gene. To assess the role of p53 and nm23 expression in colorectal tumorigenesis and the association with clinicopathological parameters, an immunohistochemical study for mutant p53 and nm23 was done using mouse monoclonal antibodies in 43 colorectal carcinomas, 55 tubular adenomas and corresponding normal mucosa. In the tubular adenomas, p53 expression was significantly correlated with the degree of atypism(p<0.05) but not with other variables as well as with nm23. In the colorectal carcinoma, there were evidence of some correlation between metastasis, laterality and p53; laterality, depth of invasion and nm23 expression, but without statistical significance. Other clinicopathologic features were not significantly correlated. In the aspect of 'adenoma-carcinoma sequence', normal mucosa was totally negative for both p53 and nm23, and they were increasingly expressed through tubular adenoma to carcinoma with statistical significance(p<0.05). Therefore, it is suggested that both p53 and nm23 expressions occur in and around the time of transition to carcinoma from adenoma but are not significantly associated with the infiltrative behavior and metastasis.
