[Application of CT virtual bronchoscope in foreign-body in children's bronchus].

OBJECTIVE: To evaluate the clinical application of CT virtual bronchoscope in foreign-body in bonchus. METHOD: The CT virtual bronchoscope were used in 21 cases with foreign-body in bronchus, all the images and reports were compared with the actual bronchoscopy. RESULT: The reports and images of CT virtual bronchoscope are very agreed with that of actual bronchoscopy. CONCLUSION: CT virtual bronchoscope is a very good complemental method in preoperative diagnosis of foreign-body in bronchus.

[Atypical pheochromocytoma].

OBJECTIVE: To improve the diagnosis and treatment of atypical pheochromocytoma. METHODS: 51 cases of pheochromocytoma were treated from July 1985 to August 1998. RESULTS: Of the 51 cases, 19 were atypical, and were characterized by silent tumor, pheochromocytoma in pregnancy, bilateral tumor, extraadrenal tumor, malignant tumor, and recurrent tumor. Open operation was performed for all kinds of cases in accordance with their special characteristics. CONCLUSIONS: Surgical extirpation is the only means for the treatment of atypical pheochromocytoma and meticulous perioperative management is essential.

[Long-term results of intravesical N-CWS instillation to prevent recurrence after surgery for bladder cancer].

OBJECTIVE: To evaluate the long term results of intravesical nocardia rubre cell wall skeleton instillation to prevent recurrence after surgery for bladder cancer. METHODS: A randomized and placedo-controlled trial on intravesical N-CWS instillation versus mitomycin-C(MMC) therapy for recurrence prevention in postopenative bladder cancer patients was carried out. RESULTS: Fourty-five patients were treated with N-CWS with 39 followed for 12 to 60 months. Thirteen patients developed recurrence. The 1-year tumor free survival rate was 87.2% and that at 5 years was 66.7%. Thirty patients as treated with MMC serving as controll with 25 followed for the same duration, twelve patients developed recurrence. The 1-year tumor free survival rate was 84% and that at 5 years was 52%. The results indicate that N-CWS gave better results with rare and milder side effects. CONCLUSION: N-CWS is believed to be one of the effective drugs in preventing bladder cancer recurrence after surgery.

[Evaluation of combined test of sequential fecal occult blood and albumin in the screening of colorectal neoplasms].

Fecal albumin test was developed and the combined use of sequential occult blood test and albumin test (SA) was evaluated and compared with sequential fecal occult blood test (S) in 365 cases diagnosed clinically and pathologically and in 883 asymptomatic individuals. In the former group, the sensitivity of detection of colorectal cancer was: 50.7% (37/73) with S and 87.7% (64/73) with SA (P < 0.001), and that of the adenoma was: 8.1% (6/74) with S and 36.5% (27/74) with SA (P < 0.001). In the latter group 2 of 3 cancer patients were detected with S while all with SA, and the detection rate of adenoma was: 4.7% (4/85) with S and 42.4% (36/85) with SA (P < 0.001) it is suggested that the additional use of fecal albumin test is of help in detecting precancerous inflammatory bowel lesions without bleeding.

Case-control study of cigarette smoking and primary hepatoma in an aflatoxin-endemic region of China: a protective effect.

Aflatoxin is believed to be a major causative agent in the high incidence of primary liver cancer seen in certain regions of the world. In Fujian Province, an aflatoxin-endemic region of China, we compared the cigarette smoking habits of 200 primary hepatoma patients with those of 200 matched nonhepatoma controls. We excluded from our study all individuals with evidence of hepatitis B virus serum antigen and/or alcoholic cirrhosis. Interestingly, two groups of hepatoma patients could be discerned. In patients more than 50 years of age, a significantly higher number of cases of primary hepatoma was found among nonsmokers than smokers (odds ratio = 2.06; 95% confidence interval = 1.32-3.20). In patients less than 50 years of age, this difference was not seen. Previous studies in the rat, mouse and duck had suggested that agents present in cigarette smoke might induce a cytochrome P450-mediated detoxication pathway, leading to protection against aflatoxin-induced primary liver cancer. Our clinical data in the present study are therefore consistent with the previous laboratory animal experiments.
