OBJECTIVES: This study is a cross-sectional study to investigate the frequency of humidifier and humidifier disinfectant usage in the general population. METHODS: A questionnaire was applied to 94 subjects (46 male, 48 female) from the general population of Gyeonggi Province. The questionnaire consisted of 3 scales (general characteristics, 5 items about humidifier usage, 5 items about humidifier disinfectant usage). RESULTS: Thirty-five (37.2%) of the 94 subjects use a humidifier and humidifier disinfectant usage was found to be 18.1%. The frequency of humidifier usage is 4.8 times per a week and the humidifier disinfectant usage is 2.4 times per a week. Humidifier usage rate was highest in January. and then tended to rise gradually from October. CONCLUSIONS: Although this study population was not representative, we can say that approximately 50 percent of the humidifier users use a humidifier disinfectant and the trend of using a humidifier has shown seasonality.

PURPOSE: While the rate of breast-feeding has been rising recently in many countries, it has been gradually falling in Korea. Accordingly, we took a survey in Jeon-ju to discover the actual state of breast-feeding and find a solution. METHODS: Eight hundred and sixty-four questionnaires of filled out by mothers who visited the seven local pediatric clinics and the clinic of pediatric department in the Presbyterian Medical Center(PMC) in Jeon-ju from January 1998 to June 1998 were analysed by ANOVA, cross analysis, frequency analysis and correlation analysis using SPSS program. RESULTS: In the case of six-months-old babies, the breast-feeding rate was 35.6%. The breast-feeding rate was higher when it came to a normal delivery, and was also related to the inperiority of infant birth order and lack of maternal academic background(P<0.05). The main reasons to switch from successful breast-feeding to formula-feeding before 6 months of age were insufficient breast-milk(49.3%). The survey shows the best thing for a infant's health is breast milk (86.0%). CONCLUSION: In order to increase the rate of breast-feeding, it's essential to educate people in school and it is necessary to create a hospital environment in which mothers can easily begin breast-feeding as soon as possible after delivery.

Schwannomas arise from the neural crest-derived Schwann cells. Their most common locations are the extremities, neck, mediastinum, retroperitoneum, and cerebellopontine angle. They have rarely been reported to occur in the breast. We herein report on a case of schwannoma of the breast in a 30-year-old woman. The ultrasonographic examination showed a well defined ovoid hypoechoic mass in the upper outer quadrant of her left breast. A presumptive diagnosis of fibroadenoma was made, and the mass was then removed. The histopathologic and immunohistochemical features confirmed the diagnosis of schwannoma of the breast.

PURPOSE: The prognosis for breast carcinoma in young women, especially those less than 35 years of age, is perceived as being unfavorable. However, the relationship of age at diagnosis and prognosis still remains controversial. METHODS: We retrospectively studied 37 breast cancer patients, who had been 35 years old or younger at the time of their diagnosis from Jan. 1990 to Dec. 1994 at the Department of Surgery, Chungnam National University Hospital. RESULTS: The factors that influenced survival were pathologic stage, tumor size, and the number of axillary node metastases, but operation method, postoperative radiation therapy, and neoadjuvant chemotherapy did not. CONCLUSION: When we compared the group with age < or =35 to the group with age >35, the former group showed worse disease free survival, but the overall survival was not worse.

A clinicopathological study was made on 17 case with leukemia cutis diagnosed in a period of 10 years frorn 1980 to 1989 in Seoul Xational University I-lospital. The results were summarized as follows : 1. There were 4 cases with acute lyrnphocytic leukernia, 7 with acute myelocytir. leukemia (AML), 5 with chronic myelocytic leukemia (CML), 1 with eosinophilic leukemia. 2. The clinical appearance of leukemia cutis included nodules (88.2%), papules, macules, plaques and ulcerative lesions. Leukemia cutis dis not show any discernible clinical qppearance with each different type of leukemia. 3. Leukemia cutis showed a wide spectrum of histopathologic features, diffuse infiltration, patchy infiltration with linear infiltration between collagen bundles, perivascular and peridnexal involvement, perivascular involvement, and mainly subcutaneous tissue involvement. There was no distinctive histopathologic pattern with each different type of leukemia. 4. The demonstration of intracytoplasmic chloroacetate esterase and lysozyme was helpful to refine the diagnosis of leukemia cutis.

BACKGROUND: Knowledge about the degree of risk and location of multiple primary cancers can facilitate the targeting of screening and surveillance practices on follow-up after treatment of cervical cancer. PURPOSE: The retrospective study was performed to evaluate the characteristics of multiple primary malignancies in patients treated for cervical carcinoma. METHOD: From data base file of gynecologic cancer patients between 1976 and 1995, total 20 patients were found to have cervical cancer and another primary malignancy. Their medical records and pathologic slides were reviewed. Follow-up information was obtained from medical records or by telephone. RESULT: There were 8 synchronous and 12 metachronous multiple primary cancers (MPC) among 20 patients. Their mean age was 51 years (range 23 ~ 68 years). The distribution of FIGO stage of the patients with cervical cancer was classified into stage I, 6 patients; stage II, 9 ; and stage III, 5. All patients showed squamous cell type histology of cervical cancer. Eight(40 %) of 20 patients developed second cancer in uterus : 6 malignant mixed Mllerian tumors(MMMT), one endometrial stromal sarcoma, and one endometrial adenocarcinoma. Seven of 8 synchronous type MPC patients are alive (median follow-up, 27 months). In contrast, only one out of 12 metachronous type MPC patients is alive(median follow-up, 114 months). The occurrence of eight malignancies including 6 MMMT, one bladder cancer, and one rectal cancer might be related with previous radiation therapy for cervical cancer. CONCLUSION: These results suggest that routine screening and surveillance work-up might not be necessary in most of patients with cervical cancer. However, the patients with cervical cancer undergoing radiation treatment have to be followed carefully with the consideration of possibility for developing second cancer in the field of irradiation.

This study was performed to demonstrate the efficacy of combination of cold-knife conization and cold-coagulation for the treatment of cervical intraepithelial neoplasia(CIN). In addition, the accuracy of the colposcopic biopsy and Pap smear compare to conization was determined. Cold-coagulation was performed simultaneously in 151 patients after cold-knife conization for diagnosis and treatment of CIN from Jan. 1995 to Dec. 1996. Medical records and pathologic slides of those patients were reviewed. Histologic comparison between the Pap smear and conization specimens showed agreement with 70 % within one grade difference ; Histologic comparison between the colpodirected punch biopsy and conization specimens showed agreement with 80 %. The margin involvement of conization was seen in 35 patients(23 %). There was a tendency of increasing rate of positive cone margin with grade of the lesion : 14 %(1/7) in CIN 1, 20 %(2/10) in CIN 2, 35 %(31/88) in CIN 3, and 33 %(1/3) in microinvasive cervical cancer. Among these 35 patients, 11 patients underwent hysterectomy and showed residual disease in 4 patients(36 %). Recurrence of CIN was found in 4 patients(16 %) with positive cone margin and 1 patient(0.9 %) with negative cone margin. Bleeding was observed in 13 patients(9 %). Two patients underwent hysterectomy because of severe bleeding. These results suggest that cold-knife conization with cold-coagulation is an effective procedure to reduce recurrence rate of the patients with CIN regardless of status of cone margin and to reduce the severity of bleeding after conization.
