Moon Hyang PARK ; Eun Kyung HONG
Korean Journal of Pathology 1991;25(5):471-475
The clinical, gross, light microscopic and immunohistochemical findings of three cases of blue nevus of the uterine endocervix were described. All three cases were incidentally found in hysterectomy specimens from middle-aged women, 45 to 48 years of age. The lesions were small and measured 1 to 4 mm in the greatest diameter. The presence of elongated, somewhat wavy and dendritic melanin-containing cells, in clusters or scattered deep in the subepithelial stroma and between the endocervical glands, was the distinct feature. The cytoplasmic granules appeared black with Grimelius and Fontana-Masson stains. The cells showed strong positive reaction with S-100 protein in perinuclear cytoplasm, in addition to the diffusely dispersed melanin granules. The demonstration of S-100 protein in the blue nevus, along with the histochemical findings, supports combined melanocytic and schwannian differentiation of the blue nevus cells.

To pursue a desirable format for the pathological diagnosis of liver cirrhosis, the authors attempted to classify 369 biopsy-proven cirrhosis on the basis of etiology and made effort to find out the morphological characteristics of each category. About 735 of total cases were HBsAg seropositive postnecrotic cirrhosis. Alcholic cirrhosis ws the second most frequent type, although accounted only 6.8%. In about 15%, the etiology was not known. Excluding the congenital biliary atresia, chronic biliary obstruction appeared to be a rare cause of cirrhosis among these biopsied cases. Of the HBsAg positive postnecrotic cirrhosis, the eAg seropositive cases tended to be micronodular and to show a higher necroinflammatory activity, in contrast to eAg seronegative cases and those complicated by hepatocellular carcinoma (HCC), suggesting that the loss of eAg is followed by a decrease of the destructive activity, active regeneration of hepatocytes and finally the development of HCC. alcoholic cirrhosis was micronodular in 64% and revealed histologic evidences of alcoholic liver disease in most cases. The results indicate that etiological diagnosis can be made in most cases of cirrhosis by the morphological characteristics and the precise clinical informations, including those on the NANB virus and the inborn error of metabolism, and that the pathological diagnosis should be more comprehensive, implicating the etiology, the nodular size and the necroinflammatory activity.

The purpose of this study was to test the effects of position change with 30degree laterally inclined position on pressure sores prevention. This study was designed as a Nonequivalent Control Group Quasi-experiment study. The subjects were collected with convenience sample of 30 patients who were hospitalized at ICU(Intensive Care Unit) of C university hospital in Seoul from March 1 to October 31, 1997. The patients were not able to change of position without help. The 15 patients were assigned to the control group and the other 15 patients to the experimental group. The both group were done position change every 2 hours and were observed whether pressure sores was developed for 2 weeks. For the experimental group, two positioning methods were alternatively used : 30degree right lateral, 30degree left lateral. For the control group, 90degree right and left lateral position were applied instead of 30degree lateral position. New Pressure Risk Assessment Scale was utilized to assess pressure sore risk. It is consists of 8 subscales which reflect sensory perception, skin moisture, activity, mobility, friction and shear, nutritional status, body temperature, and amount of medications(analgesics and sedatives). The results of this study are as follows ; 1. The incidence of pressure sores in total sample was 13 cases(43.3%) : 10 cases(76.9%) in control group, 3 cases(23.1%) in experimental group. the incidence rate of pressure sores in experimental group was significant lower than control group. 2. The sites of pressure scores development were 5 cases in trochanteric region, 4 cases in hip region, 2 cases in flank region, 1 cases in sacral region and 1 case in occipital region. Trochanteric region sores were not developed in experimental group. 3. The mean hospitalized period before pressure sores development were 7.3 day in experimental group and 4.1 day in control group. According to the results from this study, suggestions are as follows ; 1. Development of device which enable to keep 30degree laterally inclined position for 2 hours is needed. 2. It is necessary to study variously and objectively usefulness of 30degree laterally inclined position change which is applied to the other pressure risk assessment scale.

Forty-nine lobectomized hepatocellular carcinomas(HCC) were classified according to the gross anatomical features. Because the presence of cirrhosis in the remaining liver has a good clinico-pathological implication, cases of HCC were divided into non-cirrhotic(non-LC) and cirrhotic(LC) groups. In both groups, the tumors themselves belonged to either expanding, focal spreading, spreading or mixed type. Another special type, which has been called a "diffuse type" is added in the LC group with the name of "cirrhotomimetic type" Among 49 cases, 21 belonged to the non-LC group and 28 to the LC group. Most common was expanding type(20 cases, 40.8%), which was followed by spreading(32.7%), focal spreading(16.3%), mixed(6.1%) and cirrhotomimetic(4.1%) types. Expanding type of the LC group was the single most common type(13 cases, 26.5%). The accordance rate of gross typing was 0.94. Tumor masses of the LC group showed a greater tendency of having a fibrous capsule(60.7%) and a lobulated cut surface(82.1%), in contrast to those of the non-LC group (28.6% and 42.9% respectively). The patient's age and the HBsAg seropositivity were not different between the groups and between the types. Increased serum level of AFP was particularly frequent in the spreading type(81.3%) of both groups and in the cirrhotomimetic type(100%).

Cytologic findings of malignant cells obtained by fine needle aspiration from a huge retroperitoneal malignant fibrous histiocytoma were described. The smears contained numerous malignant cells, isolated or in clusters, in a bloody background. The malignant cells had abundant pleomorphic foamy or acidophilic cytoplasm with occasional multilobated vesicular nuclei and prominent nucleoli. Dual differentiation, both histiocytic and fibroblastic types, and neutrophilic inflammatory background were diagnostic of this neoplasm. The report indicated that study of aspiration cytology specimen from a soft tissue tumor was a valuable adjunct to histologic examination.

PURPOSE: This study aims to assess the effects of psychosocial work environment and self-efficacy on stress, depression, and burn-out among office workers. METHODS: Survey data were collected from 331 office workers who worked in one workplace from April 10 to 30, 2012. The impact of psychosocial work environment and self-efficacy on stress, depression, and burn-out was analyzed with hierarchical multiple regression using SAS version 9.3. RESULTS: Work-family conflicts and emotional demands were identified as main factors influencing mental health. Other work environment factors influencing mental health were role clarity for stress, possibilities for development, meaning-of work, social support-from supervisors and job insecurity for depression, and social community at work for burn-out. Self-efficacy was correlated with most psychosocial work environment and factor with independent influence on stress and depression. The final models including general characteristics, psychosocial work environment, and self-efficacy accounted for 34%, 44%, and 36% for stress, depression, and burn-out respectively. CONCLUSION: To promote mental health in office workers, there is a need to decrease work-family conflicts and emotional demands and to improve work organization and job contents, social support, and self-efficacy.

PURPOSE: Regular cancer screening for workers can help prevent cancer or allow early treatment, and is thus beneficial in improving health, reducing costs, and increasing companies' productivity. However, there has been little research on cancer screening rates of workers and related factors. The purpose of this study was to identify cancer screening rates and relevant factors among manufacturing workers. METHODS: Using a questionnaire, data were collected from 335 workers aged over 40 years recruited from seven manufacturing companies. The collected information included cancer screenings (stomach, colorectal, breast, and cervical), attitude towards cancer screening, and demographic and job characteristics. RESULTS: 72.5% of workers received stomach cancer screening (SCS), and 43% received colorectal cancer screening (CRCS). Among 86 women, 68.6% received breast cancer screening and cervical cancer screening. The attitude towards cancer screening was 29.5+/-3.78. Workers aged over 51, married, and those working in mobile manufacturing were more likely to have undergone SCS. Workers aged over 51, married, those working in mobile manufacturing, those in workplaces with more than 1,001 employees, and those with more positive attitudes toward cancer screening were more likely to have undergone CRCS. Finally, attitude affected cervical cancer screening. CONCLUSION: Workers in small-sized workplaces had lower cancer screening rates. Thus, follow-up research should assess the health environment of workplaces and develop educational programs on cancer screening that reflect attitudes towards screening.

Meningioma of unusual age of onset, location, histogenesis and histologic type is reported. The patient, 4 year-old girl, had an intradural spinal meningioma arising from lumbar nerve root with no dural attachement. The meningioma revealed glycogen-rich, clear cell type with extensive and blocky hyalinization of the stroma. The tumor shared common fibrous sheath with attached lumbar nerve, and nerve fibers were scattered within the tumor. Ultrastructurally, the tumor cells had abundant glycogen particles, intermediate filaments and intercellular desmosomes. Hyalinized material revealed large amianthoid collagen fibers.

The authors reviewed surgical materials from 20 patients with carcinoma of the extrahepatic biliary system, and a correlation between macroscopic appearance of the tumors with various clinical features and histopathologic findings was made. Microscopically, the tumors were classified into four types; Four (21%) patients had polypoid tumors, six (32%) had nodular growths, five (26%) were scirrhous constricting in type, and four (21%) had diffusely infiltrating type. Histologically all the differentiation in two cases. The degree of differentiation of the tumors was classified into 3 types: 11 (55%) patients were well differentiated, 3(15%) were moderately well and 6(30%) were poorly differentiated. All polypoid tumors were well differentiated and had low stage. No correlation in the degree of differentiation of the tumor with the stage was present. No correlation in clinical symptoms, duration of symptoms, laboratory findings with morphologic findings of the tumors was noted.
