Among the causes of death of 43 scoliotics were 5 directly due to complications of congenital heart disease. Over half (57.9%) of the remaining 38 died of cardiac or respiratory causes. The paralytic scolitoics tended to die of pneumonia or respiratory failure, while the nonparalytic scoliotics died of cardiac failure. Right ventricular hypertrophy was present in 65% of the 17 subjects examined postmortem. Electrocardiographic evidence of right ventricular hypertrophy correlated well with the postmortem findings. The vital capacity was less than 1.75 liters in 84% of the dead subjects. The case records of a further 719 living scoliotics were examined for evidence of congenital heart disease. This was found in: 34 (4.5%) of the whole group of 762, 6.9% of the congenital ; 3.4% of the idiopathic scoliotics; 22.7% of those with Marfan's syndrome.

Pneumonia caused by Pseudomonas aeruginosa occurs frequently in critically ill patients and is associated with a mortality rate of 70 per cent. An aerosol of polymyxin B was administered (2.5 mg per kilogram per day) to the upper airways of 292 patients in a respiratory-surgical intensive-care unit during a seven-month period, in an attempt to prevent Ps. aeruginosa pneumonia. Although only one of the patients studied acquired pneumonia due to Ps. aeruginosa, 10 others acquired pneumonia caused by a polymysinx-resistant organism. Seven pneumonias were caused by organisms not frequently pathogenic to man (flavobacteria, serratia and Streptococcus faecalis). The mortality rate for acquired pneumonia in this study, 64 per cent, is greater than that in previous studies in which either no polymyxin or cyclic polymyxin therapy was used. Continuous use of polymyxin B aerosol appears to be a dangerous form of therapy.

Whole lung irradiation has been effective in 10 of 17 patients irradiated solely electively (no demonstrable metastatic nodules) who are alive and well 2 to 5 years. Of an additional 17 patients with only one or two demonstrable pulmonary metastases (treated with resection or boost therapy plus whole lung irradiation), 6 are alive and well 5 to 8 years. Only one patient developed clinically significant postirradiation pneumonitis and this case proved to be fatal. Elective whole lung irradiation, especially in conjunction with modern adjuvant chemotherapy, shows promise in improving the survival of patients with tumors having a high propensity for metastasizing to the lungs.

Replication of Sendai virus, pneumonia virus of mice, and SV5 was investigated in tracheal organ cultures from 2- to 4-day-old and 2- and 4-week-old hamsters, and viral infectivity in tracheal explants was compared with that in tissue culture monolayers. Explants from 2- to 4-day-old hamsters produced higher titers of the three paramyxoviruses, as detected by hemadsorption with guinea pig and murine erythrocytes in primary rhesus monkey kidney cells. Tracheal cultures from 2- and 4-week-old hamsters yielded 1.5 and 2.5 log10 lower infectivity titers. Infected explants exhibited cytopathological changes that correlated well with cessation of ciliary activity. Viral titers in BHK-21, Vero, and BS-C-1 monolayer cells, the systems commonly used for isolation and propagation of murine paramyxoviruses, were lower than those in 2- to 4-day-old hamster tracheal explants. These observations suggest that hamster trachea organ culture could have practical application as an aid for primary isolation of paramyxoviruses from clinical specimens from rodents with respiratory ailments.

This paper gives, in detail, the causes of either liver disease or hepatomegaly in 100 patients, mostly adults, admitted to the medical wards of Angau Memorial Hospital, Lae, during 1968 and 1969. The major findings included liver cell carcinoma, cirrhosis (often with chronic active hepatitis), tropical splenomegaly, pericholangitis and hepatitis. There were 27 with miscellaneous findings including ten with normal, or almost normal, livers despite the definite enlargement. Patients with liver cell carcinoma presented late in the course of their illness and had a poor prognosis. Others, with pericholangitis, had clinical features of portal hypertension indistinguishable from that complicated cirrhosis. There was an unexpected number with chronic active hepatitis and a liver biopsy is essential for such a diagnosis. Hepatic sinusoidal lymphocytosis is almost invariably found in patients with TS but may occasionally be found in those with a non-palpable spleen. Patients with right heart failure of chronic respiratory disease, and jaundice of acute pneumonia were excluded from the study.

Three children developed extensive extrapulmonary disease in the course of fatal adenovirus type 7 pneumonia. Several clinical features, including the unexpected onset of coma, suggested the development of Reye syndrome, but biochemical and histopathologic findings were inconsistent with this diagnosis. Virologic and pathologic studies did not reveal evidence of extrapulmonary adenovirus infection, despite clinical involvement of the liver, skeletal muscle, and central nervous system. The detection in premortem sera from all three patients of adenovirus penton antigen, known to be cytotoxic in vitro, suggests a possible mechanism for the production of extrapulmonary pathology in the absence of extrapulmonary virus infection.

The acute effects of a triolein infusion in dogs were secondary to the mechanical effects of this neutral fat which was distributed in the pulmonary and systemic vascular tree of all organs without inflammatory change. Hypoxia developed immediately and became progressively worse as the infusion was continued. Pulmonary hypertension developed during the fat infusion without pneumonia, congestive heart failure or pulmonary edema. There was a slow leak of 14C triolein into the systemic circulation rather than a rapid shower, and this radioactive fat was recirculated between the pulmonary and systemic vasculature. Seventy-six per cent of the 14C triolein was retained in the lungs. Terminally, the dogs had a respiratory arrest without cardiac decompensation, cardiac arrest or pulmonary edema; cerebral fat embolism in addition to severe hypoxia appears to be the cause.

There are different patterns of development and resolution of inflammatory alveolar and interstitial pulmonary lesions. Delayed resolution of peripheral pneumonia results in lung shrinkage mainly towards the mediastinum and the apices with distortion and atypical distribution of pulmonary vasculature and compensatory hyperinflation. Resolution in perivascular and peribronchial parts is often delayed and results in scarring. Interstitial pneumonia may result directly in pulmonary fibrosis with loss of volume and honeycombing. With varying microorganisms and varying immunity chronic and atypical courses are observed more frequently.

During a 14-year period there were 65 cases of pneumonia caused by Haemophilus influenzae b; 83% were children less than 2 years of age and 80% of illness occurred in winter and spring. The roentgenographic picture was consolidative pneumonia in 75% and pleural effusions were present in 75% of all cases. Ten patients had associated meningitis and three had purulent pericarditis. Otitis media was diagnosed in 43% and H influenzae b was isolated from eight middle ear aspirates. Three patients (5%) died. Recommendations for diagnosis and treatment are made.

Trimethoprim-sulfamethoxazole has been proven effective in the treatment and prevention of Pneumocystis carinii pneumonitis in lower animals and humans. How effective the drug combination is in eradicating P. carinii from the host is not known. The immunosuppressed rat model was used to determine whether or not trimethoprim-sulfamethoxazole effectively eradicated the organism. Animals treated with trimethoprim-sulfamethoxazole for as long as 6 weeks were then placed in individual isolator cages, immunosuppressed with prednisone for 12 weeks, and sacrificed. P. carinii was found in the lungs of at least 90% of the drug-treated as well as untreated control groups. The data indicate that trimethoprim-sulfamethoxazole has a limited rather than a lethal effect on P. carinii and that protection is afforded only during the period of trimethoprim-sulfamethoxazole administration.
