PURPOSE: Lower caliceal stones treated with ESWL do fail to pass more frequently than middle or upper caliceal stones. We analyzed the results of ESWL of renal caliceal stones according to the location of calix. MATERIALS AND METHODS: We reviewed the stone-free rate in 119 caliceal stone patients treated with 3rd generation lithotriptor, EDAP LT-02 according to the caliceal location of the stone. Location of the stones were upper calix in 30, middle calix in 30, and lower calix in 59 patients. RESULTS: Stone-free rate was 90.0%(27/30 patients) in middle caliceal stones, 74.6%(44/59 patients) in lower caliceal stones, and 66.7%(20/30 patients) in upper caliceal stones. CONCLUSIONS: Stone-free rate of lower caliceal stones is higher than upper caliceal stones.

PURPOSE: To evaluate US and CT characteristics of small renal cell carcinomas with diameter less than 3cm. MATERIALS AND METHODS: We retrospectively analysed US and CT findings of the small renal cell carcinomas which were surgically confirmed. We analysed echogenicity, peritumoral hypoechoic rim, intratumoral cysts on US. We analysed CT with viewpoints of tumor margin, growth pattern, renal contour change, attenuation on pre- and postcontrast scan, homogeneity, and perirenal changes. RESULTS: The US characteristics of the small renal cell carcinomas were hyperechogenicity(89%), peritumoral hypoechoic rim(66%) and intratumoral cysts(44%). They had relatively well-defined margin(90%), smooth and round contour(90%), endophytic growth pattern(65%), and outward bulging of renal contour(75%) on CT. They had iso- or high attenuation(87%) on precontrast CT, and were relatively homogeneous low-attenuated on postcontrast CT. CONCLUSION: The constellation of US and CT findings may be helpful in the diagnosis and understanding of the internal architecture of the small renal cell carcinomas.

BACKGROUND: There were a lot of problems in the health care system of Korea, which was divided into Western and Korean Traditional Medicine since 1951. In 1976 WHO published program of The promotion and development of traditional medicine. In 1977, Korean Medical Association(KMA) asked unification of health care system to government. But there was no progress because there were the lacks of mutual respect and understanding be-tween doctors of Western and Korean Traditional Medicine. As one health care group competed with the other, so KMA proposed the unification of health system again in 1997. The objectives of this research are to analyze attitude and opinions of western medical doctors on Korean Traditional Medicine and to analyze the opinions on the unification of medical care system in Korea. METHODS: A list of western medical doctor in Seoul and Incheon was obtained from Korean Medical Association. We sampled 937 doctors by stratified random sampling method. We sent them a postal questionnaire with a prepaid return envelope two times during March and April 1997. Of the 937 questionnaire, 266 replies were received. We analyzed the preference score related referral, Korean Traditional Medicine education and unification of medical care system We analyzed the data by Chisquare test, t-test, ANCOVA. RESULTS: This study shows that the western doctors have negative attitude on Korean Traditional Medicine(M=1K8, SD=5.2). They thought Korean Traditional Medicine was not reliable because it was not scientific(79.4%). Doctor, who didn't take oriental medical education, preferred unification of health care system, but it was not statistically significant. Those who experienced oriental medical education used oriental medical treatment more frequently(F=1.17, p=0.04). The more positive attitude they have about Korean Traditional Medicine, the more frequently they refereed the patient to oriental medical doctor(t =3.57, p =0.0004). CONCLUSIONS: Western medical doctors have a negative attitude on Korean Traditional Medicine. Doctors, who did not have oriental medical education, preferred unification of health care system, but it was not statistically significant. In summary, the lack of mutual respect and understanding between doctors of the Western and Korean Traditional Medicine prevent unification of medical care system.

Hemorrhagic cystitis is potentially life-threatening sequellae of chemotherapy using oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide). Mesna contains a sulfhydryl group that is believed to bind acrolein within the urinary collecting system and reduce the hemorrhagic cystitis without affecting the chemotherapeutic potential. To date, about thirty cases of hypersensitivity or allergic reactions of the delayed and urticarial type associated with mesna have been reported. We reported two patients with systemic lupus erythematosus who developed facial rash and flushing associated with mesna which imitate malar rash.

BACKGROUND: In spite of harmfulness of smoking, the smoking rate of adult male is high in Korea and that of adolescent and women has risen recently. Most smokers try to stop smoking for themselves without doctor's help or medication, but the success rate is extremely low. Although the number of smoking-cessation clinic has risen year by year, there are few researches about smoking cessation. In this study, we tried to find the factors associated with successful smoking cessation and the effective smoking cessation modalities. METHODS: 114 smokers, who has visited the smoking-cessation clinic of Seoul Paik Hospital from Oct. 1998 to June 2000, were included. After doing a survey with basic questionnaire and smoking cessation counselling, we followed up them. We also checked their smoking behavior 6 months later. RESULTS: The success rate was 32.5%. The demographic characteristics of success group and failure group no significant difference. But the factors such as age, BMI, expiratory CO level at initial visit to hospital, nicotine dependence scale, the duration using nicotine patch and the number of visit to smoking-cessation clinic showed significant difference between the two groups. CONCLUSION: The results of logistic regression showed that BMI and nicotine dependence scale were significantly different.
