To evaluate the clinical and histopathological significance of electron dense deposits on capillary in IgA nephropathy, we reviewed and compared the clinical, laboratory, and pathological features of the patients with IgA nephropathy without loop extension of electron dense deposits(Group I, 91 cases) and IgA nephropathy with loop extension(Group II, 17cases) by ultrastructural examination using transmission electron microscope. IgA nephropathy associated with liver disease, Henoch-Schonlein purpura, systemic lupus erythematosus and the other IgA nephropathies associated with systemic diseases were excluded. The results were as follows; 1) There was no significant difference in age distribution. 2) Generalized edema was more common in group II. 3) Nephrotic ranged proteinuria(>3 g/24hr urine) was more prominent in Group II(52.9%) than Group I(8.8%). 4) Among the groups, segmental or mild deposits on the loops were noted in 13 cases, and severe and generalized deposits in 4 cases. Subendothelial deposits were noted in 6 cases, subepithelial deposits in 3 cases, subendothelial with intramembranous deposits in 1 case, subendothelial with subepithelial deposits in 1 case, intramembranous with subepithelial deposits in 2 cases, and subendothelial, subepithelial and intramembranous deposits in 4 cases. 5) The other associated ultrastructural changes of group II were diffuse effacement of foot processes with microvillous transformation, swelling or vacuolar degeneration of podocytes and glomerular endothelium. 6) According to the WHO morphologic criteria, the grade of Group II was significantly higher than Group I. From the above results, it can be concluded that the extension of electron dense deposits along the capillary loops in the cases of IgA nephropathy is highly correlated with proteinuria in the nephrotic ranged. It seems to be a poor prognostic indicator in view of the facts that it correlats with high histopathologic grading.

BACKGROUND: The purpose of this study was to examine the frequency and characteristics of needlestick/sharps injuries (NSIs) in nursing students in Korea. METHODS: The study was based on a survey of questionnaires completed by 341 nursing students who had sustained at least one NSI during clinical practice in hospitals. RESULTS: The NSI incidence rate was 36.4%. Approximately half of the students reported two to four NSIs. Most (90.2%) of the NSIs occurred on the fingertips and were caused by a hollow-bore needle (46.8%) or lancet (45.8%). Some students were exposed to used needles contaminated with unknown pathogens (37.3%), HBs Ag (2.3%), Venereal Disease Research Laboratory (VDRL) (0.8%), or HIV (0.6%). Students cited the reason for injury as carelessness, inexperience, hastiness, or recapping. Almost two-thirds of students who reported having experienced an NSI knew about post-exposure treatment. However, only one-third of the students with NSIs completed an official report. CONCLUSION: Korean nursing students lack knowledge about injury prevention, report procedures, and treatment after NSI. A revised educational approach with emphasis on occupational risk, skill development, and injury reporting is necessary to prevent NSI and to ensure that students obtain post-exposure prophylaxis.

The use of communication media suitable for the audience and message is important in conducting effective family planning IEC activities. This study 'intended to assess differential effects of various media used by the Korean program on rural women's family planning knowledge, attitude, and practice. Data for the study were collected originally for the study of family planning mothers' clubs by the School of Public Health, Seoul National University in 1973. The sample was drawn according to the principle usually employed in obtaining a small sample from a large area. Initially, a sample of 25 Gun's was selected from a total of 138 Gun's by systematic random sampling on the basis of the list of number of mother's clubs in each Gun. Secondly, from each of these primary units(Gun) selected, two second stage units(Myon) were drawn by a systematic random sampling method based on the list of the number of Li's -in each Myon. Finally, a sample of nine Li's was drawn by a simple random sampling method from each Myon selected in the second stage sampling. In this way, a total of 450 Li's, 18 Li's from each of 25 Gun's, were selected. In one of thess 18 Li's of each Gun, all the married women with a living husband, up to age 49, were interviewed. out of 1.052 women interviewed, 145 women were naturally sterile or beyond menopause, and were excluded from thib study. Thus, the analytical population consists of 90 fecundable wives, including those with tubal ligation. A series of analyses were made to examine the relationships between family planning status and selected socio-demographic and communication variables. The family planning status was measured by three indicators, one for each of family planning knowledge, attitude, and practice. The variable for family planning knowledge was created by classifying the respondents into two groups: 1) those who professed to know in detail at least one contraceptive method out of a total of five, including the loop, oral pill, vasectomy, condom, and rhythm, and 2) those who had no professed knowledge about any method. The variable for family planning attitude was dichotomized into those who had favorable attitude toward at least one method among the same list of five, and those who did not have a favorable attitude toward any method. Contraceptive status was classified into two categories of current users and non-users. The independent variables, applied to explain the family planning status, include four sociode-mographie variables and six communication variables. The socio-demographic variables are age, education, number of living children and sons, and ideal number of sons. Communication variables are frequency of exposure to family planning messages through each of the following channels: radio and/or TV, newspaper and/or magazine, 'Happy Home' and/or leaflet, public meeting and/or lecture, family planning worker, and neighbor. Major findings obtained from the analysis are summarized as follows: 1. It was observed that about 33% of the eligible women did not want to have additional children but were not practicing contraception(pong-eem). About half of these women were ever-users and the other half were never-users. They have at least perceived the need for family planning, and thus, should be a primary target population for family planning IEC activities. 2. Socio-demographic variables showed a'closer association with practice than with knowledge or attitude. 3. The communication variables affected family planning status over and above the effects of the socio-demographic variables. When the communication variables were added to the socio-demographic variables as independent variables in the multiple classification analysis, the explained variance was increased by 6.3% in knowledge, 8.7% in attitude, and 4.3% in practice. This also suggests that the communication variables exert larger effects on knowledge and attitude than on practice. Family planning adoption decisions may be influenced by many other factors as well as by family planning knowledge and attitude. 4. The Beta-coefficient was computed for each of the independent variables in multiple classification analysis. Among the media considered in this study, 1) neighborhood communication, radio and/or TV, and 'Happy Home' and/or leaflet had significant effect on family planning knowledge:2) public meetings and/or lecture, radio and/or TV, and neighborhood communication had significant effect on family planning attitude: and 3) radio and/or TV, Happy Home and/or leaflet, and home visit had significant effect on family planning practice. Although program media, neighborhood communication, and radio and/or TV appeared to be more effective than other media, no definite pattern emerged. In the interpretation of these data, however, it should be remembered tha t the frequency of contact varies with the media. 5. When women were exposed to family planning messages more frequently, they tended to have more detailed knowledge about, and more favorable attitudes toward family planning, and were more likely to he practicing family planning. 6. Media behavior differed with age and educational level. It was found that the younger the women and the higher their educational level, the more frequently they were exposed to family planning messages through radio, TV, or printed materials. On the other hand, the older the women and the lower their educational level, the more frequently they were exposed to family planning messages through meetings, home visits, and neighborhood communication. This implies that the audiences' characteristics, such as age and educational level, should be taken into account in the selection of appropriate media.

OBJECTIVE: The purpose of this investigation is to determine the frequency of chromosomal or genetic causes of recurrent spontaneous abortion. METHODS : A cytogenetic study was made in of 921 couples for 13 years from January 1984 to December 1997 in which the woman was ascertained to have had two or more spontaneous abortions at our Cytogenetic Laboratory, Institute of Reproductive Medicine and Population, Seoul National University. RESULTS : The overall incidence of chromosome anomaly was 80 out of 921 (8.7%). There were 34 cases (3.69%) of reciprocal balanced translocation and 13 cases (1.41%) of Robertsonian translocation. Also 17 cases (1.85%) of inversion and 5 cases (0.54%) of X chromosome mosiacism was observed. In the case of reciprocal balanced translocation, chromosome 8,6,7,13 were preferentially involved over others. And in the case of Robertsonian translocation, chromosome 13 was preferentially involved. CONCLUSION: Our study demonstrates that cytogenetic analysis is indicated in couples with 2 or more spontaneous abortion and about half of these disorders are reciprocal balanced or Robertsonian translocations.

Ovarian mature cystic teratoma containing benign prostatic tissue is rare and only 11 cases have been reported in the literature to date. We report a case of mature cystic teratoma of the ovary containing prostatic tissue. A 23-year-old female patient came to our hospital complaining of irregular menstruation for 3 months. Her menarche had occurred when she was 13 years old. The patient showed no evidence of virilization nor of endocrinopathy. A goose-egg-sized mass was palpable in the left lower abdomen on physical examination. Ultrasonography revealed a cystic ovarian mass with internal echogenecity. Microscopic finding was consistent with that of usual mature cystic teratoma except for a 1.5 cm focus of prostatic and bladder tissues. Prostatic tissue demonstrated strong immunoreactivity for prostatic specific antigen (PSA), prostatic alkaline phosphatase (PAP) and cytokeratin 7. Basal cells of the prostate glands were positive for high molecular weight cytokeratin (34betaE12). Although ovarian mature cystic teratoma containing prostatic tissue has been reported as a rare occurrence, a careful examination with immunohistochemical staining may increase the detection of prostatic tissue in mature cystic teratoma of the ovary.

Granuloma annulare is a common, benign, inflamatory, usually self-limited dermatosis. Disseminated perforating granuloma annulare is a rare variant of granuloma annulare. A 23-month-old female patient had asymptomatic, multiple umbilicated papules on the face, limbs including palms and soles, buttock and trunk for about 5 months. The new lesions have developed with mild fever or symptoms of upper respiratory infection. Histopathological examination revealed transepidermal elimination of mucinous degenerated collagen fibers and surrounding palisading lymphohistiocytic granuloma. After she was treated with prednisolone and antibiotics, the lesions slightly resolved, but thereafter, new lesions have developed frequently with mild fever. We herein reported a rare case of disseminated perforating granuloma annulare in the youngest patient yet reported.
