Three cases of pulmonary hypertension caused by hydatid emboli from the right side of the heart are described; cardiac catheterisation was performed in 2. One case was confirmed at operation and 2 at necropsy. The pulmonary emboli were caused by hydatid vesicles in all 3 cases and in none was there pulmonary thrombosis; free scolices were found in the pulmonary alveoli in 2. In 1 patient with r...

Pulmonary alveolar proteinosis is a rare disease characterized by the accumulation of lipoproteinaceous material derived from alveolar surfactant in the alveoli, with a consequent deterioration in gas exchange. Pathogenesis is related to impaired phagocytic function of alveolar macrophages. In recent years, a new treatment for pulmonary alveolar proteinosis-consisting of subcutaneous administra...

A 5-day-old female Holstein calf was necropsied because of lethargy, recumbency and anorexia. At necropsy, multiple gross defects were evident in several organs, including unclosed sutures of skull bones, asymmetrical orbits, doming of the skull bones, hydrocephalus, hydranencephaly, cleft palate, brachygnathia, ventricular septal defect, mitral valve dysplasia and rudimentary lungs. On microsc...

The cardiac left insufficiency with mitral dysfunction is a relevant pathology importante repercussion in the lung, leads to pulmonary edema. Pulmonary edema corresponds accumulation of fluid lung parenchyma and alveoli, can be classified as cardiogenic or non-cardiogenic. Clinical signs symptoms include presence dyspnea, cough, tachypnea, alteration normal sounds during auscultation. In this c...

Cryptogenic fibrosing alveolitis (CFA), known as idiopathic pulmonary fibrosis in the USA, is characterised by inflammation and fibrosis of the alveoli and interstitium of the lungs, favouring the subpleural and basal regions. By definition the diagnosis demands that all known causes of pulmonary fibrosis have been excluded. It is now clear that the CFA population is comprised of a heterogeneou...

Pulmonary alveolar microlithiasis (PAM) is classified as an elective dysmetabolic thesaurotic pneumoalveolitis and characterized by the presence within the alveoli of the lungs of myriad of tiny calculi. The classic presentation of the chest radiography is unmistakable with multiple small "sand-like" opacities diffusely involving both lung fields. We present a case of male infertility for hypop...

Pulmonary hypoplasia is the incomplete development of lung tissue. A reduced number of lung cells, airways, and alveoli is the hallmark and can be seen unilaterally or in both lungs. The diagnosis, however, is usually made upon pathologic examination. Here we have presented a case of a term infant presenting with severe hypoxemic respiratory failure. Despite optimizing medical and respiratory m...

This project examined the influence of preexisting, experimentally induced pulmonary emphysema on the adverse health effects in rats of chronic inhalation exposure to either nitrogen dioxide or automotive diesel-engine exhaust. Previous reports indicated that humans with chronic lung disease were among those most severely affected by episodic exposures to high concentrations of airborne toxican...

“Drowning” is defined as “suffocation by submersion, especially in water”66; it continues to be the third most common cause of accidental death in the general population and, for children in many countries, the second most common cause after road accidents.75 In the USA, 40% of drowning victims are less than 4 yr old.74 In Britain, the Office of Population Census reports that child deaths from ...
