Carboxyhemoglobin levels (COHb) were determined in residents of two Mexican cities (Mexico City and Toluca) at altitudes of 2200 and 2600 meters above sea level. The figures in non-smokers of both cities were slightly higher than those seen at sea level by others: 1.63% in Mexico City and 1.54% in Toluca versus 0.5-1% at sea level. There were no intercity differences in smokers and non-smokers, but there were intergroup differences in both cities (p less than 0.01 in Mexico City, and p less than 0.05 in Toluca). Our findings suggest that the most important source of carbon monoxide in smokers is tobacco smoking, and that the COHb level may be reliable index to establish active smoking.

Among 1,855 thoracic neoplasms seen from 1971 to 1990, there were 923 with bronchogenic carcinoma (CaBr), 50%. The relation male:female was 1.95:1. Sixty three period thirty one percent were male. The histologic type were epidermoid 32.2%, adenocarcinoma 28.4% and small cells 13.2% in men; in women adenocarcinoma 38.9%, epidermoid 28.9% and mixed 7.7% with a significative difference for both sexes for these neoplasms. Other types were less frequent. There is significative difference between smokers and non smokers of both sexes p < 0.001. Epidermoid, adenocarcinoma, small cells, large cells and mixed were the most frequent in male smokers, in women these varieties were more frequent in nonsmokers. Comparison with the reference group with no CaBr suggests that epidermoid, adenocarcinoma and small cells carcinomas have a great possibility to be found in male smokers. Ninety two period two percent of cases were stage III (Tumor Node MetastasIs) with no chance for radical treatment. Only 94 were subject to surgery with 36 total resections. CaBr is an important problem in the General Hospital of Mexico. Antismoking programmes must be stressed in relation to the frequency of CaBr in smokers.
The authors present the result of an investigation on the use of cement and bentonite in the treatment of pancreatic fistulas that coexisted with permeable duct and which has been closed by the local application of said elements.
