In order to evaluate the role of cytopathologic diagnosis of sputum, bronchial washing and bronchial brushing in the diagnosis of lung cancer, we performed this study. The patients included in this study had undergone sputum, bronchial washing and brushing cytology over the 20-month period of 1985 through 1987. The total number of specimens was 5,495 of 2,242 patients, including 4,830 sputa and 665 bronchial washing and brushings. The average number of sputa and bronchial washings and brushings per case was 2.4 and 1.2 respectively. Among them, about 10% were unsatisfactory specimen, and three-fourths were negative specimens. In sputum cytology, the diagnosis of "atypical cells" was given to 3%, "suspicious for malignancy" was given to 1%, and "malignancy" was given to 13%. In bronchial washing and brushing cytology, the diagnosis of "atypical cells", "suspicious for malignancy" and malignancy" was given to 6%, 3%, and 20% respectively. The cases diagnosed as "atypical cells" in cytology were actually malignancy in 95% and 84.8% of sputum and bronchial washing and brushings respectively, and the "suspicious for malignancy" were actually malignancy in 100% in both methods. The detection rates of malignancy were 50.4% and 55.2% in sputum and bronchial washing and brushing respectively, and the specificity was 100% in both methods. The accuracy of cell typing was 92% in sputum and 89.7% in bronchial washing and brushing.

OBJECTIVES: To evaluate the relation between diagnostic clinical parameters and the depth of trophoblastic invasion in tubal pregnancy and decide the most predictable parameter. Methods: Total 50 patients who were confirmed as tubal pregnancy pathologically, from Jan. to Dec. 1997, were included in this study. Menstrual missed periods was calculated by clinical history, volume of gestational mass was calculated as sphere, beta-hCG was titered with preoperative blood sample. All surgical specimens were examined pathologically and divided into two groups such as intraluminal and extraluminal, defined as intact tubal musculature and trophoblastic invasion beyond musculature, n=22 and n=28, respectively. Statistical analysis was performed among three parameters and between each parameter and the depth of trophoblastic invasion. Statistical analysis included were Student's t-test, Chi square, linear regression, and linear correlation analysis using SPSS statistical package and statistical significance was determined as p<0.05. RESULTS: There was a correlation between volume of gestational mass and beta-hCG(p<0.05), but not between beta-hCG and missed period or volume of gestational mass and missed period. beta-hCG level was 1843.7+/-1524.7 mIU/ml(Mean+/-SD) in intraluminal and 12144.3+/-10561.6 mIU/ml(Mean+/-SD) in extraluminal. There was a predictive correlation between beta-hCG and the depth of trophoblastic invasion(p<0.05), and cut off level 3,500 mIU/ml showed the highest sensitivity, specificity, positive predictive value, negative predictive value, 0.79, 0.86, 0.88, 0.76, respectively. Two parameters(volume of gestational mass and missed period) had no ability to predict whether intraluminal or extraluminal. CONCLUSION: We suggest that successful medical treatment of tubal pregnancy depend on lesional intactness of vasculature for drug delivery. In patient selection for medical treatment, it should be important to predict intraluminal type because of intact vasculature. Of clinical parameters, beta-hCG is single most predictive parameter, cut off level of 3,500 mIU/ml was the most reasonable level in this study.

46, XX male is a rare sex cluomasomal constitution characterized by the development of bilateral testis in persons who lack a Y chomosome. The majority of affected persons have normal external genitalia and usually seek medical advice due to infertility, hypogonadism and/or gynecomastia in adulthood. Although Y chromosomsl sequences can be detected in the majority of male subjects with 46, XX karyotype, several studies have shown thst approximately 10 % of patients lack Y chromosomal material including the SRY ( sex-determining region of Y-chromosome) gene. Several hypothesis have been proposed to explain the etiology of this constitution. 1. Translocation of the testis-determining factor (TDF) fiom the Y to the X chromosome or autosome. 2. Acquisition of Y chromosome function by a mutant autosomal or X-linked gene. 3. Undetected mosaicism with Y-bearing cell line 4. Loss of Y chmmosome hom the XXY Klinefelter zygote. We experienced a case of 46, XX male who was 30 years old. We report a case with review of the literature.

In terms of treating diseases, minimally invasive treatment has become a key element in reducing perioperative complications. Among the various minimally invasive treatments, cryotherapy is often used in urology to treat various types of cancers, especially prostate cancer and renal cancer. In prostate cancer, the increased incidence of low-risk, localized prostate cancer has made minimally invasive treatment modalities an attractive option. Focal cryotherapy for localized unilateral disease offers the added benefit of minimal morbidities. In renal cancer, owing to the increasing utilization of cross-sectional imaging, nearly 70% of newly detected renal masses are stage T1a, making them more susceptible to minimally invasive nephron-sparing therapies including laparoscopic and robotic partial nephrectomy and ablative therapies. This article reviews the various outcomes of cryotherapy compared with other treatments and the possible uses of cryotherapy in surgery.

A Statistical observations were done on 587 pediatric patients who were diagnosed as having congenital heart disease by cardiac catheterization angiography and operation at Dong San Hospital Keimyung University, during the period of January 1982 to june 1987. The results were as follows 1) Out of 587 patients, 317 cases were male and 276 cases were female. There were female preponderance in atrial septal defect and patent ductus arteriosus, whille in male tetralogy of Fallot, pulmonary stenosis, and ventricular septal defect. 2) The incidence of congenital heart disease were as folliws;ventricular septal defect 35.7% tetralogy of Fallot 17.5%, patient ductus arteriousus 13.9%, arterial septal defect 7.5% and pulmonary stenosis 2.9%. 3) Most of the patients were visited hospital for the first time between the age of 2 and 10 years. 4) Assosiated anomalies of major congenital heart disease were as follows:the most commonly associated anomaly in ventricular septal defect were pulmonary stenosis and patent ductus arteriosus. Pulmonary stenosis was frequently associated with atrial septal defect. Right sided aortic arch and pentalogy were assosiated with tetralogy of Fallot. The mitral regurgitation was associated with patent ductus arteriosus mostly. 5) The overall surgical mortality was 6.8%. The mortality was high in tetralogy of Fallot(16.1%), transposition of great vessels(28.5%).

BACKGROUND: The changes of serum TNF-alpha, sTNFR, sIL-2R and sICAM-1 levels have been recently reported in some cancer patients but the clinical significance of these cytokines is not clearly established. To define the changes and clinical significance of these cytokines in patients with hepatocellular carcinoma (HCC), serum levels of TNF- alpha, sTNFR, sIL-2R and sICAM-1 were measured. METHODS: The serum levels of TNF-alpha, sTNFR, sIL-2R and sICAM-1 were measured before and after transarterial chemoembolization (TACE) by enzyme immunoassay in 20 patients with HCC and 10 adult healthy subjects as controls. These patients were divided into two groups, no response (NR, 14 cases) and partial response (PR, 6 cases) on the basis of changes of tumor size, new growth foci on the ultrasonographic or CT findings, and serum levels of alpha-fetoprotein. RESULTS: Serum levels of TNF-alpha, sTNFR, sIft-2R and sICAM-1 were significantly higher in all patients with HCC than in those of adult healthy controls (p<0.01). Serum levels of TNF-alpha after TACE tended in to be higher in comparison with those before TACE in the NR group (p<0.1), but those were not significantly different between before and after TACE in the PR group. Serum levels of sTNFR, sIL-2R and sICAM-1 were not significantly different between after and before TACE in both groups. CONCLUSIONS: These results suggest that serum levels of TNF-alpha, sTNFR, sIL-2R and sICAM:-1 in patients with HCC before therapy are significantly increased, compared with those of the control group, and the measurement of serum TNF-alpha levels may become useful in the diagnosis and monitoring of hepatocellular carcinoma in the future.
