[Behavior of predictive variables of exacerbations of the COPD in the neumological hospital of Cuba.].

The use of predictive variables of exacerbations of the COPD is not a practice generalized in our environment, for what we cannot characterize the exacerbating patient neither to design strategies for its integral handling. There was carried out a prospective descriptive study to correlate in patient with diagnosis of COPD from the Neumologic Hospital of Cuba, with the objective of determining the association between clinical, functional variables and imagenological and the exacerbations frequency a year. The population was constituted for patients with clinical diagnosis of COPD and the sample for those patients with confirmed diagnosis that they completed the inclusion approaches.

[Pancoast tumor. A clinical case].

We described a patient who was diagnosed with a Pancoast tumor in the Neumológico Benéfico Jurídico Hospital. This neoplastic non metastatic disease more frequently affects the brachial plexus. Therefore, a differential diagnosis of the painful shoulder was carried out and the patient was admitted in our center with the probable Pancoast tumor diagnosis.

Adjuvant interferon gamma in patients with pulmonary atypical Mycobacteriosis: a randomized, double-blind, placebo-controlled study.

Background: High antibiotic resistance is described in atypical Mycobacteriosis, mainly by Mycobacterium avium complex (MAC).

Methods: A randomized, double-blind, placebo-controlled clinical trial was carried out in two hospitals to evaluate the effect of interferon (IFN) gamma as immunoadjuvant to chemotherapy on patients with atypical mycobacteria lung disease. Patients received placebo or 1 x 106 IU recombinant human IFN gamma intramuscularly, daily for one month and then three times per week up to 6 months as adjuvant to daily oral azithromycin, ciprofloxacin, ethambutol and rifampin.
