Fine needle aspiration of the breast is an important diagnostic tool in malignant lesions, but is also useful in differentiation of inflammatory breast diseases mimicking carcinoma clinically and radiologically. Recently, the authors have experienced eight biopsy-proven cases of chronic inflammatory diseases of the breast, which consisted of 4 cases of duct ectasia, 2 cases of fat necrosis, and a case of tuberculous mastitis and granulomatous mastitis respectively, Their cytoiogic features mainly based on the components and the relative frequency of inflammatory cells were evaluated for differential diagnosis of chronic inflammatory breast diseases. The results are as follows ; 1. In cases of duct ectasia, varying amount of neutrophils, mononuclear leukocytes, histiocytes and multinucleated giant cells were intermixed with benign epithelial cell clusters. 2, Abundant fat tissue fragments were diagnostic for fat necrosis. Histiocytes and mononuclear cells were main components but not rich, and neutrophils and giant cells were infrequently observed. 3. Characteristic granulomas composed of epithelioid cells, mononuclear leukocytes and Langhans' type giant cells and lymphocytic infiltrates were conspicuous in tuberculous mastitis, and occasionally neutrophils, necrotic materials and epithelial cell clusters were found. 4. In granulomatous mastitis, epithelioid cell granulomas were also noted but numerous neutrophils and histiocytes were intermingled within or outside the granulomas.

In a six-year period(1988. 5-1994. 4), fine needle aspiration cytology(FNAC) of 322 pulmonary lesions from 296 patients were performed at Soonchunhyang University Hospital. Of these 322, malignancy was diagnosed cytologically in 139(43.2%), suspicious malignancy in 7(2.2%), negative in 164(50.8%), and insufficient material in 12(3.8%). Malignant lesions consisted of 54 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 18 cases of small cell carcinoma. They were verified by histologic examination in 70 cases. There were 2(0.6%) false positive cases due to florid bronchoalveolar hyperplasia and atypical bronchial epithelial cells associated with granulomatous lesion. The overall accuracy rate was 90%, the sensitivity 84.3% and the specificity 94.7%.

OBJECTS: This open study was designed to investigate the efficacy and safety of risperidone in the treatment-resistant patients with chronic schizophrenia. 24 patients were entered on the 8-week open trial. A total of 3 patients discontinued risperidone treatment before the end of the study. METHODS: We investigated risperidone's efficacy and its side effects in 21 patients with treatment-resistant chronic schizophrenia, who had previously been treated with different kinds of classical antipsychotic drugs but with insufficient clinical effect or distressing extrapyramidal side effects, over a 8-week period. After 3- 7 days of placebo wash-out period, patients were assigned to receive risperidone. The overall clinical efficacy was assessed at the 1st, 2nd, 4th, and 8th week of the treatment using the PANSS and the CGI. Safety and tolerability were assessed by the ESRS, the UKU side effect rating scale, the vital signs, and the laboratory tests including CBC, urinalysis, liver function test, and ECG. RESULTS: Clinically PANSS total score and CGI severity score on the end study point showed a significant improvement compared with baseline state. Significant improvements in both PANSS positive and negative subscale scores was as early as week 1 through week 8. Nine(43%) among of the 21 patients showed at least a 20% decrease in total PANSS scores. The tolerability of risperidone was geneally found to be good. Insomnia(52%), fatigue(52%), and sedation(52%) were the most common side effects. CONCLUSION: These results suggest that risperidone may be a effective antipsychotic agent in the treatment of refractory schizophrenia. However, double-blind comparative trial between risperidone and clozapine should be performed to further clarify the efficacy of risperidone in treatment-resistant patients with chronic schizophrenia.

OBJECTIVE: The purpose of this study was to evaluate the pregnancy outcomes of heterotopic pregnancy. METHODS: Retrospective analysis was done in 24 patients who were diagnosed as heterotopic pregnancy between January 2000 and April 2008. Patients' characteristics, risk factors, treatment methods and pregnancy outcomes were evaluated. RESULTS: A total of 24 patients were diagnosed as heterotopic pregnancy, all of these had undergone assisted reproductive technique. The mean age was 31.5 years and the mean gestational age at diagnosis was about 8 weeks. The most common etiology of infertility was tubal factor (54.2%). Four (16.7%) of the women had undergone ovulation induction, eighteen (75%) had undergone in vitro fertilization, but 2 patients (8.3%) had undergone assisted reproductive technique at other hospital and we didn't know the exact method. The most common of ectopic site was tube (75%), and 50% of ectopic sites were ruptured status at diagnosis. Three (12.5%) of 24 patients were diagnosed ectopic pregnancy after dilatation and evacuation due to missed abortion, 4 (16.7%) were diagnosed ectopic pregnancy and missed abortion, and 17 (70.8%) were diagnosed ectopic pregnancy and living intrauterine pregnancy at the time of diagnosis. Laparotomy was done in 3 patients (12.5%) and laparoscopy was done in 21 patients (87.5%). Among 17 patients who had normal intrauterine pregnancy, 12 (70.6%) delivered singletones, 2 (11.8%) delivered twins, but 3 (17.6%) patients were lost follow up. CONCLUSION: Heterotopic pregnancy should be considered in pregnant woman with abdominal pain or vaginal bleeding, although confirmed normal intrauterine pregnancy using ultrasonography at early gestational age, especially if the woman have treatment history for infertility. And early diagnosis and proper management are important.
