Comparison of right ventricular weight at necropsy in interstitial pulmonary fibrosis and in chronic bronchitis and emphysema.

The ventricular weights in 43 patients with interstitial pulmonary fibrosis were retrospectively compared with those in 172 patients with emphysema and chronic bronchitis. The mean right ventricular weight of patients with interstitial pulmonary fibrosis and those with emphysema and chronic bronchitis was 85.5 g (SD 23.2) and 88.8 g (34.3), respectively. Thirty five patients (81%) with interstitial pulmonary fibrosis had a right ventricular weight over 65 g compared with 124 (72%) of those with emphysema. Fifty three per cent of both those with interstitial pulmonary fibrosis and those with chronic bronchitis and emphysema had a right ventricular weight greater than 80 g. Differences between the two groups were not significant. These results suggest that the prevalence of right ventricular hypertrophy and pulmonary hypertension in interstitial pulmonary fibrosis is similar to that found in chronic bronchitis and emphysema.

Mixed malignant tumour of the lung.

A mixed malignant tumour of the lung intermediate in type between pulmonary blastoma and carcinosarcoma is described. The epithelial component consisted of squamous carcinoma, undifferentiated carcinoma, and clefts lined by bland epithelial cells. The supporting stroma was composed of pleomorphic sarcoma, fibrosarcoma, chondrosarcoma, osteosarcoma, and indeterminate mesenchymal tissue. The tumour was removed surgically, but the patient died postoperatively with rapidly developing multiple bony and soft tissue metastases. Subcutaneous metastases showed the appearnce of poorly differentiated pleomorphic sarcoma. Published reports of mixed malignant lung tumours are reviewed.

Histiocytic medullary reticulosis with hypogammaglobulinaemia and disseminated intravascular coagulation.

A case of histiocytic medullary reticulosis in a 45-year-old man is described. The presentation with a swinging pyrexia is typical. Associated features were very low levels of all immunoglobulins and proved disseminated intravascular coagulation. Heparin therapy was given and the difficulties of controlling such treatment are demonstrated. It is concluded that an increased awareness of the condition as a cause of pyrexia might lead to an improvement in prognosis.

Changes in the carotid body and the ventilatory response to hypoxia in chronically hypoxic rats.

1. Young rats were kept in a hypoxic chamber for 2-11 weeks and compared with littermate control animals. 2. The carotid bodies of the hypoxic rats enlarged, resembling those of men and animals living at high altitude. 3. Permanent blunting of the ventilatory response to hypoxia did not occur. Immediately on removal from the chamber, the rats, lightly anaesthetized, showed a smaller increase in ventilation during hypoxia than did control animals but this difference disappeared after 3 days' recovery in normoxia.
