A review was made of the records of 27 patients admitted to National Jewish Hospital who developed or experienced a reactivation of pulmonary tuberculosis during pregnancy or the first 12 month post partum. Sixteen patients had drug-resistant disease, and 11 had drug-susceptible disease. The drug-resistant group had more extensive radiographic(More)
Although recent epidemiologic studies have established that patients with chronic medical illness and depressed mood are more disabled than euthymic patients, detailed data on the benefits and risks of antidepressant treatment in medically high-risk patients have been slow to accumulate. The authors have examined multiple outcome indicators in patients with(More)
The possibility that surface tension may affect the hydrostatic transmural pressure of pulmonary vessels and the development of pulmonary edema was studied in anesthetized, open-chested dogs. Isogravimetric pressure (the static intravascular pressure at which transmural osmotic and hydrostatic pressures are balanced such that net fluid flux is zero and lung(More)
Systemic to pulmonary flow from bronchial circulation, important in perfusing potentially ischemic regions distal to pulmonary vascular obstructions, depends on driving pressure between an upstream site in intrathoracic systemic arterial network and pulmonary vascular bed. The reported increase of pulmonary infarctions in heart failure may be due to a(More)
1. Hypoxic and hypercapnic ventilatory drives were measured in eight healthy male subjects before and after ingestion of ethanol, in a dose of 17 mmol/kg body weight. 2. A significant decrease in hypoxic ventilatory drive was observed at 20 min after ethanol (P less than 0.05). A significant depression in hypercapnic drive was observed at 70 min after(More)
An increase in sympathetic nervous system (SNS) activity in the obese has been described by some but not all investigators. It is possible that an increase in SNS tone may play a role in the predisposition to atherosclerotic cardiovascular disease noted in the obese. The effect of dietary weight loss or exercise training on resting SNS activity in(More)
