Two cases of meningococcal meningitis complicated by pulmonary oedema are described. The pulmonary arterial wedge pressure was raised in the one case studied. Profound sympathetic over-activity may be the cause of the pulmonary oedema occurring in this situation. If this is so, adrenergic blockade would appear to be a rational ...

Five patients with severe acidosis and pulmonary oedema complicating cholera were seen at the Cholera Research Laboratory, Dacca, in a two-year period. All had had inadequate treatment. Their disease resulted in acidosis prior to admission; only the two who subsequently survived received volumes of sodium bicarbonate solutions sufficiently large to ...

Dirofilaria immitis, the dog heartworm, has been identified in the pulmonary granulomas of 5 patients from the greater Charleston area; this is the largest series of such cases from one medical center. The patients had no pulmonary symptoms. On roentgenogram the lesions were all about 2 cm in size, of ...

Phycomycosis of the skin manifested as a spontaneous solitary ulcer of the leg in a patient with uremia. The infection later spread to the lungs and produced fatal pulmonary infarction. Histopathologic study of the lesions revealed broad nonseptate fungal hyphae that had invaded vascular channels, with areas of necrosis and ...

Light and electron microscopy was used to examine portions of the brain, the circle of Willis, and the internal carotid arteries of normal cats and rabbits, of sham-operated ones, and of those whose cervical lymphatics had been ligated. Carbon was injected into the cerebral cortex of some lymphoedematous animals. It ...

Paraquat (1,1'-dimethyl-4,4'-bipyridylium dichloride) has in the last decade gained popularity as an effective weedicide. It is marketed for commercial use as a liquid concentrate Gramoxone ICI (20% paraquat). Accidental or intentional ingestion of Gramoxone has caused 232 human deaths between 1964 and 1973 (Anon 1974). Most human patients suffer transient ...

In the present study the pathogenesis of the pulmonary damage following infusion of thrombin in combination with a fibrinolysis inhibitor, AMCA, in the dog was elucidated. An important mechanism in the development of the pulmonary damage following infusion of thrombin and AMCA seems to be an increased vascular permeability in ...

Pontine astrocytomas may fungate, encircling the basilar artery and pontomesencephalic vein and intruding between these structures and the clivus. The tumor thus may prevent anterior displacement of these vascular structures against the clivus or produce paradoxical posterior displacement. However, the pontine arteries are usually swept forward by the tumor nodules ...

An increased venous capacity and a decreased myocardial contractility can be expected in patients with an acute spinal cord lesion at or above T6. Both factors may contribute to a high incidence of arterial hypotension and pulmonary oedema in these patients especially during anaesthesia. We feel that the Swan-Ganz catheter ...

A life-threatening respiratory disease, characterized by fever, cough, dyspnoea, cyanosis and wide-spread bilateral pulmonary infiltrates, developed in a 40-year-old patient receiving intermittent methotrexate therapy for psoriasis. Blood eosinophilia accompanied the illness. A prominent feature in the clinical picture was a discrepancy between auscultatory findings and the pronounced changes in the ...

Fixation of lungs at necropsy by inflation with formaldehyde vapour was used in a combined radiological and pathological study of pulmonary oedema. Pulmonary oedema was found in 79% of lungs examined. The earliest phases affect the interstitial tissue with oedematous connective tissue planes and distension of pulmonary lymphatics. These changes ...

A combined radiological and autopsy study of pulmonary oedema enables recognition of oedema lines other than Kerley 'A', 'B' and C lines. These have been designated 'D' lines. At least three varieties have been noted: (i) thick, long often angular lines seen mainly anteriorly overlying the heart shadow on the ...

Clinical details are given of two patients who developed ipsilateral pulmonary oedema following re-expansion of their spontaneous pneumothoraces by intercostal drainage of air. The possible mechanisms underlying the oedema are discussed, and prior literature is analysed. Reference is made particularly to its predictability and to precautions recommended to minimize the ...

Soon after the introduction of a new type of explosive in the North Staffordshire coal field, a number of coal miners were seen with acute pulmonary oedema (Kennedy, 1960). These and other coal miners who gave a history of excessive exposure to fumes from shotfiring over a number of years, ...

Pericardiotomy followed by intravenous injection of adrenaline (1 mg/kg body weight) provides a reliable method for the production of acute massive lung oedema in the dog. The lung wet weight: heart wet weight ratio is found to be the best assessment of the degree of lung oedema. A ratio greater ...

Ventilatory function declines during the early stages of irradiation for bronchial carcinoma. This decline is potentially dangerous if the tumour narrows the trachea or both main bronchi. The protective effect of preliminary treatment with prednisolone or mustine before irradiation was studied in 88 patients by serial estimations of forced expiratory ...

Isolated pulmonary metastases from testicular tumours were treated by surgery in nine patients. Six are alive and well with no clinical evidence of recurrence. Three of the survivors were operated on more than 10 years ago. Surgical treatment should be considered in such patients, particularly as the metastases are often ...

This is the case report of a 47-year-old man who swallowed a powerful commercial herbicide containing paraquat. He developed oral, oesophageal, renal, and hepatic damage and, at an earlier stage than is usual, severe pulmonary changes from which he made a satisfactory recovery. The disordered pulmonary function and production of ...

A new differential colour medium prepared with an extract of potatoes and carrots produced ochre-brown pigmentation in Cryptococcus neoformans colonies, identical to that obtained with Guizotia abyssinica seed extract. The pigment formation was observed to be specific for this pathogenic yeast in a survey of 534 yeast-positive specimens during routine ...
