Susceptibility of an avian pneumovirus isolated from Minnesota turkeys to physical and chemical agents.

Survival characteristics of a Minnesota avian pneumovirus (APV) isolated from a turkey nasoturbinate, propagated in tissue culture, and exposed to various physiochemical treatments were determined. These characteristics included survivability under various conditions. Specifically, APV was viable at temperatures of -70 C and -20 C for over 26 wk, 4 C for less than 12 wk, 20 C for less than 4 wk, 37 C for 48 hr, and 50 C for less than 6 hr. In addition, APV survived 12 freeze/thaw cycles with no loss of activity. With a variable pH for 1 hr, the titer was unaffected between the levels of pH 5 and 9. Several disinfectants, including quaternary ammonia, ethanol, iodophor, a phenol derivative, a biguanide, and bleach, were all effective in reducing the viability of the virus. After 7 days of drying at room temperature, the APV remained viable and was recovered on cell culture.

Assessing independence in community living.

Community health professionals are frequently faced with the dilemma of assessing "independence in community living" in individuals with physical limitations. However, the validity of standardized assessment of "independence in community living" continues to be limited. Standardized assessment tools are unable to capture the true meaning of "community living" and "independence" being articulated through the Independent Living Movement by people who have physical limitations. We use examples from our experience with the Community Living Skills Project in Nova Scotia to highlight three limitations of standardized assessment of individuals in light of the Independent Living Movement's interpretation of "independence in community living". Standardized assessments were unable to attend to and integrate the complexities of interactional elements, individual differences and the concept of "independence" as personal control and mutual dependence. We conclude that individual assessment requires tools with greater sophistication than those currently available. This discussion is important since individual assessment guides decisions which have far reaching effects on people's lives and on the demands placed on limited health and social services.

The influence of acute preoperative pulmonary infarction on the results of heart transplantation.

The presence of acute pulmonary infarction is not uncommon in severely ill patients and is considered by some to be a contraindication to heart transplantation. It has been our policy to accept these patients for operation. The purpose of this investigation is to examine the results of this policy in patients receiving immunosuppression with cyclosporine A and azathioprine. Between September 1982 and April 1985, eight patients undergoing heart transplantation demonstrated clinical and radiographic evidence of acute preoperative pulmonary infarction. These patients represented 5.5% of our heart transplantation population during this period (total = 145). The age range in these eight patients was from 22 to 55 years. Congestive cardiomyopathy was present in four patients, and four patients had ischemic cardiomyopathy. All patients were New York Heart Association functional status class IV. Five of the eight patients were on inotropic support, and one patient had associated renal failure. Pulmonary infarcts were located in the right, middle, or lower lung field in seven patients and in the left lower lung field in one patient. All patients were treated perioperatively by intensive physiotherapy and specific antibiotics. In four patients the lesions resolved on medical treatment alone. Three patients developed extensive empyema and required chest drainage with or without decortication. Two of these patients survived with complete resolution of the lung lesions, and one patient died from prolonged renal failure and sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)
