In comparison with normal cervix, mitosis occur more frequently in cervical intraepithelial neoplasia(CIN) and are seen at high levels, suggesting that CIN may be associated with a progressive dysfunction in proliferative activity of cervical cells. This study aims that expression of proliferative cell nuclear antigen(PCNA) was examined to determine proliferative activity at the cell of CIN. Sixty four colposcopic biopsies from patients with cytologically and/or colposcopically dtagnosed condyloma and CIN. The cases were classified as follows ; 19 as normal cervix and condyloma, 15 as CIN I, 16 as CIN II and 14 as CIN III. Immunohistochemical detection of PCNA was performed on paraffin sections by the streptavidin-biotin peroxidase method using the monoclonal antibody PC10. There was a statisically significant correlation between the CIN grade and the PCNA grade(p<0.05). In addition, the PCNA grade showed significant correlation with mitotic grade(p<0.05) and the CIN grade was also observed(p<0.05). This study suggests that the cell proliferation index as detected immunohistochemically using PCNA may be a useful adjunct to histopathological diagnosis of various grades of CIN.

BACKGROUND: Recently technetium-99m sestamibi (99mTc MIBI), which dose not require withdrawal of thyroid hormone, has been used for imaging of thyroid carcinoma. The aim of this study was to determine the clinical usefulness of Tc MIBI scintigraphy after total thyroidectomy for thyroid carcinoma. The results were compared with those of standard 131I scintigraphy. METHODS: One hundred twelve patients with a median age of 44 years (range, 14-76 years) were included in the study. After optimal endogenous thyroid stimulating hormone stimulation (>50 mIU/mL), whole body scintigraphy using 4 mCi of 'I and 20 mCi of Tc sestamibi were done simultaneously. Concomitantly serum thyroglobulin and anti-thyroglobulin antibody levels were checked. If abnormal findings on any of the scintigraphic methods or high levels of thyroglobulin (> 10ng/mL) were detected, diagnostic imaging studies were done to confirm the existence of the disease. And high dose (150-200 mCi) 'I was administered as therapy and then whole body scans were performed again after the therapy. The presence or absence of thyroid cancer was established by pathologic, radiologic, and/or high dose I scan findings. RESULTS: In 11 patients, Tc MIBI scan revealed positive accumulations which were not found on 131I scan, of whom 6 had elevated thyroglobulin levels. In these cases, 5 cases were interpreted to have normal thyroid remnant and 6 cases showed pathologic findings (2 lung, 1 lymph node, 1 lung and lymph node, 1 local recurrent cancer, and 1 false positive accumulation of 99mTc MIBI). Metastasis or residual cancer were confirmed histologically in 1 and radiologically in 4 cases. Negative 99mTc MIBI scans, despite of positive I scans, occurred in 9 patients, of whom 2 had abnormal thyroglobulin levels. Seven cases were interpreted to have thyroid remnant, 2 cases were confirmed to have lung metastasis, and another one was misinterpreted due to breast shadow. CONCLUSION: In conclusion, these results suggest that 99mTc MIBI scan may have similar sensitivity and specificity for the detection of residual or metastatic differentiated thyroid carcinoma. The 99mTc MIBI scan, especially in cases of negative 131I scan despite of abnormal thyroglobulin levels, can be used as a very useful complementary diagnostic tool.

BACKGROUND: Whole body 131I scan is routinely performed in the postoperative evaluation of patients with differentiated thyroid carcinoma to detect recurrence and functioning metastasis. Previous reports suggested that posttreatment whole body scan had higher rate of detecting metastatic lesions that were not visualized by pretreatment images. We observed the frequency of discordance of the two scans and analysed the clinical significances. METHODS: Forty-one patients with differentiated thyroid carcinoma underwent radioactive iodine-131 whole body scans after administration of diagnostic dose (4 mCi) and then therapeutic dose (100~200 mCi of iodine-131). The median age of the patients was 46.9 +/- 15.7 years (range, 17~76). RESULTS: In 16 of the 41 patients (39.0%), pretreatment scan showed additional uptakes that were not seen in the pretreatment scan. Serum thyroglobulin was elevated in 13 of the 16 patients. Of the 22 patients who had been received radioactive iodine therapy previously, eight patients showed new additional lesions in the therapeutic scans but there was no significance according to the history of radioactive iodine therapy, Addisional uptakes after therapeutic dose were noted in neck area in 9 cases, lung in 2 cases, bone in 4 cases and mediastinum in one case. Diffuse hepatic uptake was definitely seen in 7 cases and there were 2 cases whose scans showed liver uptake without any thyroid uptake. CONCLUSION: Posttreatment whole body scan is more sensitive to detect residual tissues and metastasis compared to the usual pretreatment diagnostic whole body scan, and it is suggested that posttreatment whole body scan should be routinely performed after 'I therapy in patients with differentiated thyroid carcinoma for exact evaluation.

Angiomyofibroblastoma is a distinctive, hitherto uncharacterized, benign soft tissue tumor of the vulva with histology similar to an aggressive pelvic angiomyxoma. It can be distinguished from an aggressive angiomyxoma by its circumscribed borders, higher cellularity, more numerous blood vessels, the frequent presence of plump stromal cells, minimal stromal mucin, and rarity of erythrocyte extravasation. We experienced a case of angiomyofibroblastoma of the vulva occurring in a 45-year-old woman. The lesion was a well-defined but not encapsulated mass, 4.5x4.2 cm. Histologically the mass was characterized by alternating hypercellular and hypocellular edematous zones in which abundant blood vessels were irregularly distributed. Immunohistochemically, the spindled, plump spindled, and oval stromal cells were reactive for vimentin and desmin, but not for cytokeratin, or S-100 protein.

This project was a service-cum-research effort with a quasi-experimental study design to examine the health benefits of an integrated Family Planning (FP)/Maternal & Child health (MCH) Service approach that provides crucial factors missing in the present on-going programs. THE SPECIFIC OBJECTIVES WERE: 1) To test the effectiveness of trained nurse/midwives (MW) assigned as change agents in the Health Sub-Center (HSC) to bring about the changes in the eight FP/MCH indicators, namely; (i) FP/MCH contacts between field workers and their clients (ii) the use of effective FP methods, (iii) the medically supervised deliveries, (iv) prenatal care by medically qualified personnel, (v) medically supervised deliveries, (vi) the rate of induced abortion, (vii) maternal and infant morbidity, and (viii) preinatal & infant mortality. 2) To measure the integrative linkage (contacts) between MW & HSC workers and between HSC and clients. 3) To examine the organizational or administrative factors influencing integrative linkage between health workers. STUDY DESIGN: The above objectives called for quasi-experimental design setting up a study and control area with and without a midwife. An active intervention program (FP/MCH minimum "package" program) was conducted for a 2 year period from June 1982-July 1984 in Seosan County and "before and after" surveys were conducted to measure the change. SERVICE INPUT: This study was undertaken by the Soonchunhyang University in collaboration with WHO. After a baseline survery in 1981, trained nurses/midwives were introduced into two health sub-centers in a rural setting (Seosan county) for a 2 year period from 1982 to 1984. A major service input was the establishment of midwifery services in the existing health delivery system with emphasis on nurse/midwife's role as the link between health workers (nurse aids) and village health workers, and the referral of risk patients to the private physician (OBGY specialist). An evaluation survey was made in August 1984 to assess the effectiveness of this alternative integrated approach in the study areas in comparison with the control area which had normal government services. METHOD OF EVALUATION: a. In this study, the primary objective was first to examine to what extent the FP/MCH package program brought about changes in the pre-determined eight indicators (outcome and impact measures) and the following relationship was first analyzed. b. Neverthless, this project did not automatically accept the assumption that if two or more activities were integrated, the results would automatically be better than a non-integrated or categorical program. There is a need to assess the "intergration process" itself within the package program. The process of integration was measured in terms of interactive linkages, or the quantity & quality of contacts between workers & clients and among workers. Intergrative linkages were hypothesized to be influenced by organizational factors at the HSC clinic level including HSC goals, sltructure, authority, leadership style, resources, and personal characteristics of HSC staff. The extent or degree of integration, as measured by the intensity of integrative linkages, was in turn presumed to influence programme performance. Thus as indicated diagrammatically below, organizational factors constituted the independent variables, integration as the intervening variable and programme performance with respect to family planning and health services as the dependent variable. Concerning organizational factors, however, due to the limited number of HSCs (2 in the study area and 3 in the control area), they were studied by participatory observation of an anthropologist who was independent of the project. In this observation, we examined whether the assumed integration process actually occurred or not. If not, what were the constraints in producing an effective integration process. SUMMARY OF FINDINGS: A) PROGRAM EFFECTS AND IMPACT. 1. Effects on FP use: During this 2 year action period, FP acceptance increased from 58% in 1981 to 78% in 1984 in both the study and control areas. This increase in both areas was mainly due to the new family planning campaign driven by the Government for the same study period. Therefore, there was no increment of FP acceptance rate due to additional input of MW to the on-going FP program. But in the study area, quality aspects of FP were somewhat improved, having a better continuation rate of IUDs & pills and more use of effective Contraceptive methods in comparison with the control area. 2. Effects of use of MCH services: Between the study and control areas, however, there was a significant difference in maternal and child health care. For example, the coverage of prenatal care was increased from 53% for 1981 birth cohort to 78% for 1984 birth cohort in the study area. In the control area, the same increased from 41% (1981) to 65% (1984). It is noteworthy that almost two thirds of the recent birth cohort received prenatal care even in the control area, indicating that there is a growing demand of MCH care as the size of family norm becomes smaller. 3. There has been a substantive increase in delivery care by medical professions in the study area, with an annual increase rate of 10% due to midwives input in the study areas. The project had about two times greater effect on postnatal care (68% vs. 33%) & delivery care (45.2% vs. 26.1%). 4. The study area had better reproductive efficiency (wanted pregnancies with FP practice & healthy live births survived by one year old) than the control area, especially among women under 30 (14.1% vs. 9.6%). The proportion of women who preferred the 1st trimester for their first prenatal care rose significantly in the study area as compared to the control area (24% vs 13%). B) EFFECTS ON INTERACTIVE LINKAGE. 1. This project made a contribution in making several useful steps in the direction of service integration, namely; i) The health workers have become familiar with procedures on how to work together with each other (especially with a midwife) in carrying out their work in FP/MCH and, ii) The health workers have gotten a feeling of the usefulness of family health records (statistical integration) in identifying targets in their own work and their usefulness in carrying for family health. 2. On the other hand, because of a lack of required organizational factors, complete linkage was not obtained as the project intended. i) In regards to the government health worker's activities in terms of home visiting there was not much difference between the study & control areas though the MW did more home visiting than Government health workers. ii) In assessing the service performance of MW & health workers, the midwives balanced their workload between 40% FP, 40% MCH & 20% other activities (mainly immunization). However, 85-90% of the services provided by the health workers were other than FP/MCH, mainly for immunization such as the encephalitis campaign. In the control area, a similar pattern was observed. Over 75% of their service was other than FP/MCH. Therefore, the pattern shows the health workers are a long way from becoming multipurpose workers even though the government is pushing in this direction. 3. Villagers were much more likely to visit the health sub-center clinic in the study area than in the control area (58% vs. 31%) and for more combined care (45% vs. 23%). C) ORGANIZATION FACTORS (ADMINISTRATIVE INTEGRATIVE ISSUES). 1. When MW (new workers with higher qualification) were introduced to HSC, it was noted that there were conflicts between the existing HSC workers (Nurse aids with less qualification than MW) and the MW for the beginning period of the project. The cause of the conflict was studied by an anthropologist and it was pointed out that these functional integration problems stemmed from the structural inadequacies of the health subcenter organization as indicated below; i) There is still no general consensus about the objectives and goals of the project between the project staff and the existing health workers. ii) There is no formal linkage between the responsibility of each member's job in the health sub-center. iii) There is still little chance for midwives to play a catalytic role or to establish communicative networks between workers in order to link various knowledge and skills to provide better FP/MCH services in the health sub-center. 2. Based on the above findings the project recommended to the County Chief (who has power to control the administrative staff and the technical staff in his county) the following; i) In order to solve the conflicts between the individual roles and functions in performing health care activities, there must be goals agreed upon by both. ii) The health sub-center must function as an autonomous organization to undertake the integration health project. In order to do that, it is necessary to support administrative considerations, and to establish a communication system for supervision and to control of the health sub-centers. iii) The administrative organization, tentatively, must be organized to bind the health worker's midwives's and director's jobs by an organic relationship in order to achieve the integrative system under the leadership of health sub-center director. After submitting this observation report, there has been better understanding from frequent meetings & communication between HW/MW in FP/MCH work as the program developed. Lessons learned from the Seosan Project (on issues of FP/MCH integration in Korea). 1) A majority or about 80% of the couples are now practicing FP. As indicated by the study, there is a growing demand from clients for the health system to provide more MCH services than FP in order to maintain the achieved small size of family through FP practice. It is fortunate to see that the government is now formulating a MCH policy for the year 2,000 and revising MCH laws and regulations to emphasize more MCH care for achieving a small size family through planning practice. 2) Goal consensus in FP/MCH should be made among the health workers & administrators, especially to emphasize the need of care of "wanted" child. But there is a long way to go to realize the "real" integration of FP into MCH in Korea, unless there is a structural integration FP/MCH because a categorical FP is still first priority to reduce the rate of population growth for economic reasons but not yet for health/welfare reasons in practice. 3) There should be more financial allocation: (i) a midwife should be made available to help to promote the MCH program and coordinate services, (ii) there should be a health sub-center director who can provide leadership training for managing the integrated program. There is a need for "organizational support", if the decision of integration is made to obtain benefit from both FP & MCH. In other words, costs should be paid equally to both FP/MCH. The integration slogan itself, without the commitment of paying such costs, is powerless to advocate it. 4) Need of management training for middle level health personnel is more acute as the Government has already constructed 90 MCH centers attached to the County Health Center but without adequate manpower, facilities, and guidelines for integrating the work of both FP and MCH. 5) The local government still considers these MCH centers only as delivery centers to take care only of those visiting maternity cases. The MCH center should be a center for the management of all pregnancies occurring in the community and the promotion of FP with a systematic and effective linkage of resources available in the county such as i.e. Village Health Workers, Community Health Practitioner, Health Sub-center Physicians & Health workers, Doctors and Midwives in MCH center, OBGY Specialists in clinics & hospitals as practiced by the Seosan project at primary health care level.
