The need for fiberoptic bronchoscopy in the patient with hemoptysis and a normal or nonlocalizing chest roentgenogram remains a subject of debate. Currently, diagnostic fiberoptic bronchoscopy is recommended as the investigative procedure of choice. To develop predictors that identify the patient in whom fiberoptic bronchoscopy is most likely to be(More)
Noninvasive rebreathing measurements of pulmonary tissue volume (Vt) and pulmonary capillary blood flow (Qc) theoretically and experimentally vary with the rebreathing maneuver. To determine the cause of these variations and identify ways to minimize them, we examined the consequences of varying the volume inspired (VI), rebreathing rate (f), volume(More)
Brain compression with subdural air causes pulmonary hypertension and noncardiogenic pulmonary edema (A. B. Malik, J. Appl. Physiol.: Respirat. Environ. Exercise Physiol. 42: 335-343, 1977). To see whether air emboli to the lungs rather than brain compression caused these findings, anesthetized dogs received intravenous air infusions, subdural air(More)
In a controlled, randomized prospective clinical trial the utility of intravenous hyperalimentation (IVH) in the administration of and tolerance to chemotherapy was tested. The conclusions reached were 1) IVH is safe with a tolerable infection rate; 2) infectious complications correlate significantly with the nutritional status of the patient, with the(More)
We reviewed our experience with 115 patients with pleural effusion in whom bronchogenic carcinoma was suspected who underwent fiberoptic bronchoscopy (FOB) to identify those for whom the procedure was useful. In 6 of 12 patients with hemoptysis, 8 of 12 with a mass or infiltrate, and 8 of 18 with atelectasis with negative fluid cytology and 3 of 7 with(More)
Preventive measures against CAP are important yet underused. Cost-effective preventive measures against CAP include influenza and pneumococcal vaccines, especially in patients over the age of 65 and other high-risk groups. There are now two antiviral agents, amantadine and rimantadine, that can be used both for prophylaxis and for therapy of influenza A(More)
Backgroud. To establish the characteristics of the deceased and the death causes. Methodology: Transversal study descriptive, with intake patients elder than 65 years old in an Internal Medicine Department. The variables analized were: age, sex, intake date, discharge date, days of hospital stay, chronic disease previous, admission cause, deceased,(More)
Bronchoscopic examination to diagnose lung metastases has not been as rewarding as in primary lung cancer. Despite a lower expected yield, we believe the procedure has value in certain patients, ie, those with clinical findings of endobronchial disease. To determine better the value of bronchoscopy in this population, we retrospectively reviewed records of(More)
