The studies that have been performed on respira­tory muscle endurance are based on the capacity of the respiratory muscles to sustain and generate high levels of pressure. The most common test consists of generating a pressure against a given resistive inspi­ratory load. In our study, we used the Nickerson, Keens and Kelsen methods, that consist […]

It can be seen in Table 1 that there is evidence that the patients suffered a moderate obstruction of air flow and the volumes are increased. Three of the patients had a Deo of less than 80 percent due to clinical and radiologic signs of pulmonary emphy­sema. The average TLIM of the sample was 3.7 […]

Sample The study was conducted on eight male patients with COPD in stable phase, that is, the patients had not shown any symptoms of acute relapse in a period of at least two months prior to the study. The average age was 60.57 ±7.59 years, the height was 162.14 ±10.43 cm, and the weight was […]

To or some years now, resistive inhalational loads have been used to evaluate the endurance capacity of the inspiratory musculature under exertion. The capacity to sustain the muscular exertion required to inhale depends on the force and duration of the inhalational muscle contraction, which is determined by the pressure-time ratio. It is known that healthy […]

Following embryonic differentiation, the human nail grows continuously throughout life at a rate of about 0.5 to 1.2 mm per week, slowing down with age. Trauma appears to stimulate growth, while immobilization retards the proc­ess. Toenails appear to grow at a third to a half the rate of fingernails, and full replacement from base to […]

Case 1 A 71-year-old man was brought to the VA Medical Center, Johnson City, by his family, who stated that he had a one-week history of fever, chills, and cough productive of yellow sputum. Prior VA records showed that the patient was a long-term smoker, smoking 1 to 2 packs/day for more than 30 years, […]

The bedside clinician, searching for clues to the presence of disease, is often rewarded by careful examination of the patients hands. The nails offer many clues to the patients physiology and habits. Yellow pigmentation of the nail plate caused by cigarette smoking is especially common (partic­ularly in our Veterans Administration Hospital); clubbing of a “nicotine […]
