To evaluate the effectiveness of conization in the diagnosis of cervical cancer, the histopathologic finding of 464 consecutive cases were analized with respect to the cytology, punch biopsy and hysterectomy. Cold knife conization was performed under direct visualization(naked eye conization) from January, 1987 to Octorber 1994 at department of Obstetrics and Gynecology, Kosin Medical Center. The results were summerized as follows : 1. The rate of agreement and underdiagnosis of between pap smear and naked eye conization were 43.7% and 47%. 2. The rate of agreement and underdiagnosis of between punch biopsy and naked eye conization were 64.5% and 21.8% 3. Subsequent hysterectomy was done on the 382 case and their incidence of residual disease rate was 44.2%(169 cases). Their incidence of residual lesion was increased with severity of the carcinomatous change. 4. The rate of complication undergoing conization was 8.4%(39 cases).

BACKGROUNDS: With the recent elucidation of genetic basis of Rh blood group, it is now available the molecular genotyping methods for Rh blood typing. These can be used when serological typing is difficult. This study was conducted to investigate the usefulness of Rh genotyping method for Koreans. METHODS: Genotyping for Rh C/c and E/e was performed in peripheral blood DNA samples from 34 blood donors by polymerase chain reaction using sequence-specific primers (PCR-SSP). The PCR determined genotypes were compared with serologically determined phenotypes. RESULTS: The Rh C/c and E/e genotyping results of 34 blood donors were full concordance with the results of their serologic phenotyping. CONCLUSIONS: Rh genotyping method on the basis of Rh genetic model can be applied to Koreans. This genotyping method would be useful tool in prenatal Rh typing of fetus at risk of hemolytic disease and when serotyping is not available for example massive transfusion.

A fabrication method of inner and outer crown using CAD/CAM is presented. The information of abutment teeth is transferred to a computer through a 3-dimensional scanner. A Konus inner and outer crown is designed on a computer and a real crown is machined based on this design using CAM. This method can save laboratory time and reduce inaccuracies compare to conventional casting procedure. A stone model with six prepared abutment teeth from a patient was used in this study. Three dimensional information from the model was transferred to a computer using a contact type 3dimensional scanner with a 25micrometer accuracy. All margins were identified on a computer image where there is a change in surface taper of a model. To provide a cement space, the image of a inner surface of a Konus inner crown was duplicated 25micrometer apart from the surface of a prepared abutment teeth image. The cement space was 20micrometer at the cervical margin. All Konus crowns were machined with a 10micrometer accuracy. It was concluded that this method can reduce working-time for the laboratory process and increase accuracy. A further research is required to make a simplified process for a more complex prosthesis.

One hundred and thirty trimethoprim-resistant R plasmids derived from of Escherichia coli isolated from clinical specimens and feces of healthy collegians were examined for incompatibility, EcoRI endonuclease restriction fragment pattern, and Southern hybridization with DHFR I, II, III, V, and VII probe. 1. Most trimethoprim-resistant R plasmids were resistant to ampicillin, tetracycline, chloramphenicol, gentamicin, and kanamycin, and showed multiple drug resistance and various antimicrobial resistance patterns. 2. Trimethoprim-resistant R plasmids ranged from 90 to 50 kilobase and 42.3% of R plasmids tested were classified to incompatibilty group Inc FI, Inc FII or Inc FIV, 3. Among 48 random selected R plasmids from various origin, 14 R plasmids (including 9 of 14 Inc FII plasmids and 3 of 14 Inc FI plasmids) hybridized with DHFR VII oligonucleotide probe but others did not respond to any of DHFR probes used. 4. Most R plasmids showed various EcoRI endonuclease fragments and different reaction sites by Southern hybridization. Six plasmids showed identical or nearly identical molecular weight, EcoRI endonuclease fragment patterns and different sites of Southern hybridization. But 2 Inc FII plasmids derived from urine and feces showed identical pattern. These findings, if confirmed by further studies, suggest that normal flora E. coli can act as reservoir of resistant genes and, consequently, as a factor in the dissemination of these genes among enteric pathogens and need to be examined further.

BACKGROUND: The pathogenesis of alopecia areata is still unknown, however autoimmune mechanism is strongly suggested. The topical immunotherapy using potent sensitizer has been used as new therapeutic modality. By this method in one half and to one third of the patients, hair growth is observed. OBJECTIVE: To evaluate the immunological profile between responders and non-responders to dphencyprone (DPCP) topical immunotherapy in alopecia areata patients. METHODS: Aker sensitization, DPCP was applied to the patients' scalp weekly for three months. Before and after treatment the therapeutic effect was evaluated by clinical observation by following items: complete baldness, baldness+vellus, baldness+terminal hair and normal hair. Peripheral T cell and T cell subsets, B cell and delayed hypersensitivity with various antigens were evaluated before and after treatment. RESULTS: The immunologic difference between responders and non-responders was not statistically different. CONCLUSION: It is suggested that no major immunologic difference was observed between responders and non-responders before and after DPCP topical immunotherapy. Local mechanism seems to be related in the response to immunotherapy.

PURPOSE: The purpose of this study was to develop and evaluate a Korean questionnaire to measure resilience in children with chronic illness. METHODS: Item construction was drawn from an extensive review of the literature, existing questionnaires and interviews with parents. Content validity was tested by experts. To further refine the questionnaire and test its reliability and validity, data were collected from the 202 children with asthma, diabetes mellitus or nephrotic syndrome. Corrected items were used to total correlation coefficient and test-retest reliability. Questionnaire testing was conducted using factor analysis, Cronbach's alpha, and correlation coefficients. Validity of the questionnaire was tested using internal consistency, construct validity, and criterion-related validity. RESULTS: Components of the questionnaire were in three domains; interpersonal characteristics, characteristics of coping, and intrapersonal characteristics. Factor analysis is showed five factors; positive self-understanding, self-reliance, resourcefulness, perception of positive family relationships, and intimacy. The questionnaire showed a high internal consistency. A significant positive correlation with the Numerical Rating Score and negative correlation with the Child Depression Inventory support the validity of the questionnaire. CONCLUSION: This instrument demonstrated high reliability and validity. Therefore, this instrument can contribute to the evaluation of resilience of chronically ill children and to any subsequent intervention as well as to develop a theory for resilience.

PURPOSE: The main purposes of this descriptive survey study were to describe parenting stress and needs of mothers of children with atopic dermatitis. METHOD: Data were collected from 111 mothers of children under 6 year-old with atopic dermatitis registered at one university affiliated medical center in Seoul. The instruments used for this study were a self-report questionnaire, Parenting Stress Index (PSI) Short Form by Abidin, and an open question to identify nursing needs. Descriptive analysis, Pearson correlation and contents analyses were done. RESULT: The mean score for parenting stress was 77.25 (range: 12-60), for parent domain 31.50 (range: 12-60), Parent-Child domain 21.02 (range: 11-55) and child domain was 24.72 (range: 11-51). There was a significant positive relationship between parenting stress and severity of symptom (r=0.192, p<.005). The maternal stressors included extra housework related to symptom management, treatment related to atopic dermatitis, personality and behavior of child, and financial problems. CONCLUSION: the mothers of children with atopic dermatitis have high parenting stress from various stressors and needs. It is recommended that nursing interventions should include stress management and take into consideration the educational needs of mothers.

Atypical laryngeal carcinoid is a rare tumor with a poor prognosis, mostly occurring in the supraglottic larynx. It is a subtype of neuroendocrine carcinoma which should be separated from typical carcinoid and small cell carcinoma. The histogenesis and standardized classification of laryngeal neuroendocrine carcinoma have not been clearly defined. In this report, we present two cases of atypical laryngeal carcinoid, one occurring in a 67 year old male and the other in a 54 year old female. Indirect laryngoscopy revealed a polypoid supraglottic mass, approximately 3 cm in diameter. Microscopically, each case showed a moderate degree of pleomorphism, tumor necrosis and frequent mitoses. The immunohistochemistry revealed a strong positive reaction for chromogranin, neuron specific enolase and cytokeratin. Each patient had distant metastasis, noted within 4 months after resection (liver and stomach), and died postoperatively at 5 and 20 months, respectively. A brief review of the literature concerning the biological behavior, histogenesis and pathology of atypical laryngeal carcinoid was performed.
