BACKGROUND Pulmonary insufficiency is the nexus of late morbidity and mortality after transannular patch repair of tetralogy of Fallot. This study aimed to establish the feasibility of implantation of the novel Medtronic Harmony transcatheter pulmonary valve (hTPV) and to assess its effect on pulmonary insufficiency and ventricular function in an ovine model of chronic postoperative pulmonary i...
Treatment of most of the pulmonary mycoses has been unsatisfactory until the advent of a new antifungicidal drug, Amphotericin B. This has so far shown promise of being a useful addition to the meager stock of therapeutic weapons we now have available. Aspergillosis, and particularly pulmonary aspergillosis, has not been much of a problem in the past because of its rarity. This, however, is not...
In human and ovine fetuses, glucocorticoids stimulate leptin secretion, although the extent to which leptin mediates the maturational effects of glucocorticoids on pulmonary development is unclear. This study investigated the effects of leptin administration on indices of lung structure and function before birth. Chronically catheterized singleton sheep fetuses were infused iv for 5 days with e...
Bluetongue virus (BTV) infection causes a haemorrhagic disease in sheep, whereas BTV infection typically is asymptomatic in cattle. Injury to the endothelium of small blood vessels is responsible for the manifestations of disease in BTV-infected sheep. The lungs are central to the pathogenesis of BTV infection of ruminants; thus endothelial cells (ECs) cultured from the pulmonary artery and lun...
Study of mortality from pulmonary tuberculosis in Ontario between 1881 and 1961 reveals a steady decline in rates since the beginning of this century, affecting both sexes and all age groups. This decline has been much faster in the younger than in the older age groups. When the mortality rates are studied for groups of men and women born within 10-year periods (10-year cohorts) an orderly patt...
Alveolar proteinosis is a rare disease characterized by the accumulation of a proteinoseous material inside the alveolus. Various forms of treatment have been tried without much success. Pulmonary lavage has been found effective in bringing relief to patients as well as objective amelioration. This presentation describes the technique used and the problems encountered.
Twenty-two pulmonary carcinoid tumours (18 central, 4 peripheral) were seen in this department over an 11-year period. The majority of the tumours displayed a mixed pattern on microscopic examination, and cell-nest formation was a prominent feature in sixteen. The findings are at variance with the results of a similar series reported from Japan and suggest that there is regional variation in th...
The purpose of this study was introduction and evaluation of efficacy and safety of retrograde thromboembolectomy in acute massive pulmonary emboli. The method is described in a 56-year-old woman with acute massive pulmonary thromboemboli. Postoperative course was uneventful. The described surgical technique is not a panacea and definitely not the whole answer, but is a big part of the solution...
Human pulmonary dirofilariasis (HPD) is an uncommon disease in the United States. Dirofilaria is commonly known as "heartworm" based on the false belief that the worm resides in the heart which was based on findings from early necropsy reports. The first case was reported as an incidental autopsy finding in 1941. Since then only 87 more cases have been reported so far. We present an interesting...
