| the evolving pattern of pediatric endocarditis from 1960 to 1985. | a diagnosis of endocarditis was made in 37 patients (three days to 21 years old) on the basis of the following: histology in 11; at least two positive blood cultures in patients with underlying cardiac disease in 22; less than two positive blood cultures, vegetations seen at echocardiography and a suggestive clinical syndrome in four. twenty-six patients had primary endocarditis (17 with pre-existing cardiopathy, nine with normal hearts). the 11 others developed secondary endocarditis following ... | 1990 | 2344561 |
| airborne microbial contents in two types of swine confinement buildings in quebec. | airborne microorganisms were isolated with a sampler in two types of swine confinement buildings (farrowing units and fattening units). respirable (particles less than 5 microns) and total dust fractions were obtained. samplings were repeated every 2 weeks for a total of 6 samplings per unit between january and april. the predominant microorganisms isolated were bacteria (up to 1.25 x 10(6) cfu/m3) with an important fraction in the respirable size range (up to 0.5 x 10(6) cfu/m3). only small qua ... | 1990 | 2353639 |
| factors influencing the development of serum precipitins to farmer's lung antigen in quebec dairy farmers. | a total of 888 randomly selected dairy farmers participated in an epidemiological study to evaluate the prevalence of precipitins to farmer's lung antigens, and the socioeconomic factors associated with their presence. precipitins were present in 75 farmers (8.4%) (65 to micropolyspora faeni, seven to aspergillus spp, two to both aspergillus and micropolyspora faeni, and one to aspergillus and thermoactinomyces vulgaris). the titres ranged from a dilution of 1/32 to a concentration of x 2 (oucht ... | 1985 | 4038823 |
| elimination of microorganisms from dental operatory compressed air. | compressed air is used to power high-speed handpieces, as well as to dry and clean surfaces in the oral cavity during patient treatment, in all dental operatories. the compressed air used in the dental operatories located in large institutions such as universities or hospitals is generally obtained from a central source, and is produced by continually running compressors. in operatories located in private practice settings, compressed air is obtained from small on-site air compressors, which may ... | 1998 | 9473876 |

| a cluster of cases of aspergillus endocarditis after cardiac surgery. | aspergillus endocarditis is an ominous condition whose prevalence is increasing in the hospital population. despite the life-threatening nature of the disease, detection of the source, establishment of the diagnosis, and treatment remain highly challenging. a cluster of three cases of aspergillus endocarditis recently encountered at the montreal heart institute are presented. | 2004 | 15172295 |
