[Current utilization of anticholinergics in the chronic obstructive pulmonary disease treatment].

Only 20% of patients with chronic obstructive pulmonary disease receive appropriate treatment. The most utilized among anticholinergics has been ipratropium bromide in inhalation very valued for its safety but that should be utilized every 6 hours. In these setting the average dose is 26% and when the patient takes de drug every 24 hours the dose index is 84%. Tiotropium is the new anti-cholinergic administered through respiratory airways that should be taken every 24 hours. It is more effective for improving functional residual capacity with levels much higher than ipratropium bromide. Furthermore, tiotropium is better than ipratropium bromide for improving the quality of life and for diminishing the frequency of exacerbations, one of the causes for improving the quality of life.

[The effect of peroperative transfusion on survival in resected lung carcinomas].

This paper analyzes the influence of perioperative transfusion on survival after lung cancer surgery. Between January 1991 and December 1995, we enrolled 405 patients, 196 of whom received transfusions and 209 of whom did not. Follow-up extended to December 1997. Excluded were patients undergoing exploratory thoracotomy (n = 92), those who died during the postoperative period (n = 19) and those lost to follow-up (n = 13). The final number of patients in the study was 281 (136 who received transfusions and 145 who did not). We analyzed age, sex, general clinical status measured on the Eastern Cooperative Oncology Group (ECOG) scale, histological type and TNM staging. Single and multiple variable analyses were performed. At the end of the study 158 patients were alive and 123 had died. Transfusions were used more often in pneumonectomies (p < 0.001) and in patients with an ECOG score of 2 (p < 0.01). Survival at 36 and 60 months, calculated using the Kaplan-Meier method was 52% and 30%, respectively, for those who had received transfusions, and 53% and 49%, respectively, for those who had not. The differences were not statistically significant (p > 0.1). Multivariant analysis failed to demonstrate an influence of transfusion on survival (relative risk of 1.08; 95% confidence interval 0.72-1.61; p > 0.1). We conclude that there is no negative prognostic effect of perioperative transfusion.

[Estimation of initial interobserver variability of forced spirometry in the multicenter epidemiological study IBERPOC. Scientific Committee of the IBERPOC study].

To estimate the interobserver variability and degree of agreement for basic spirometric parameters before beginning field work for the IBERPOC Project. Study of agreement between 7 observers (pneumologists) and a gold standard, using a scheme of incomplete balanced and randomized blocks with an equal number of spirometric measurements (n = 3) per patient and an equal number of measurements (n = 9) per observer performed at the same session. The study population consisted of 14 patients with different degrees of air flow obstruction and 7 normal volunteers. Statistically significant differences attributable to subjects (inter-patient variability) were found for the three variables analyzed. Variability attributable to the observer was found for FVC and FEV1 but not for FEV1/FVC. The greatest interobserver differences were found for FEV1, such that 4 of the 7 observers recorded values that were significantly different from the mean (p < 0.05). The differences were less marked for FVC and for the FEV1/FVC ratio, with only 2 observers recording significantly different values for each variable. The high degree of reproducibility as well as the excellent interobserver agreement found in this standardization session provide an a priori guarantee of validity for spirometric measurements and rule out the existence of differential bias in data recorded at the various geographic areas involved in the study.

[Comparative study of procaterol and salbutamol in single inhaled doses].

The bronchodilator effect of 0.02 mg of procaterol compared to 0.2 mg of salbutamol as a reference drug administered by single dose inhalation, has been tested in 15 asthmatic patients with a stable clinical situation, using a double-blind study. The clinical value of the administered dose was determined by FEV1, FEV 25-75%, PEF, MEF 50% FVC, SRaw, VC and FRC. These functional tests together with the evaluation of secondary and cardiovascular effects were performed every hour during a 12 hour period. The results revealed that the procaterol aerosol was more potent (although not statistically significant) than the salbutamol, and had a longer activity time. There were no differences in the secondary effects which were mild and transitory. These results suggest that procaterol is a potent bronchodilator, with a long-lasting activity and minimal cardiovascular and adverse side effects.

An outbreak of Q fever in the Basque country.

The main clinical manifestations of 42 cases of Q fever occurring in an outbreak in Valmaseda, Spain during March, April and May 1982 are described in this paper. The benign character of the acute disease is emphasized. Further epidemiologic studies must be done to determine the incidence of Q fever in the Basque country.
