A prospective analysis of 155 patients with pulmonary embolism was undertaken to describe the radiographic characteristics of associated pleural effusions and related abnormalities. Approximately one half of these patients had pleural effusions. Patients with other potential causes of effusion, such as heart failure, pneumonia, or cancer, were eliminated from further analysis. In the remaining 62 patients, radiographic evidence of pulmonary infarction accompanied pleural effusions in one half of the cases. One third of patients with parenchymal consolidation had no evidence of effusion. Atelectasis and other nonspecific radiographic abnormalities occurred in less than one fifth of the cases. Typically, pleural effusions were small and unilateral, appeared soon after symptoms of thromboembolism began, and tended to reach their maximal size very early in the course of the disorder. Pulmonary infarction was associated with larger effusions that cleared more slowly and were more often bloody in appearance on thoracentesis. Chest pain occurred in all but one patient and was a valuable diagnostic clue. Pain and pleural effusions were always ipsilateral and almost always unilateral, but neither correlated well with the presence or time course of infarction. Effusions that were delayed in onset or that enlarged late in the course were associated with recurrent pulmonary embolism or superinfection. These radiographic features may be helpful in the diagnosis and management of pulmonary embolism.

In British Columbia between January 1970 and December 1974 active tuberculosis was diagnosed only after death in 69 cases; this was more frequent for miliary tuberculosis (31% of reported cases) than for advanced pulmonary tuberculosis (3% of cases). Although 28% of the patients were more than 75 years old, some were much younger, and 38% of the latter were alcoholics. More than 50% of the patients had been hospitalized before death, for a mean of 14.5 days; they were most frequently thought to have pneumonia or cancer at the time of death. Clearly, increased awareness of the continuing presence of tuberculosis in our society is needed.

One hundred twenty-seven patients with Hodgkin's disease, Stages III-IV, received total nodal irradiation. Of these, 101 patients were managed primarily by radiation therapy employing the split course sequential segmental radiation technique called the "3 & 2". A dose of 3800-4000 rad is delivered in 2 phases in an overall period of 12 to 13 weeks (TDF 61-64; 1094-1148 rets). For various reasons, the remaining 26 patients received their mantle irradiation to full doses 3800-4000 rad in 4 weeks (TDF 63-66; 1112-1184 rets) without rest periods and a few were irradiated after failing chemotherapy. Of the 101 patients treated between 1969-1974 using the "3 & 2" technique, 2 developed pericarditis (2.0%), none manifested symptomatic pneumonitis (0%), and 3 hypothyroidism )3.0%). The low incidence of severe complications is primarily the result of the technique employed to give total nodal irradiation. The overall incidence of Herpes Zoster was 42% (53/127), and there was a slightly higher incidence when TNI was given following splenectomy.

From 1955 up to 1976 we observed 1140 patients with cancer of the colon and rectum. Out of these 134 patients had obstruction. Only in 40.3% radical resections could be done; mortality rate (22.0%). 54.7% underwent palliative procedures, 8% were inoperable. The primary mortality rate of this group came up to 62%. Causes were: peritonitis (44.5%), pneumonia (17.3%), pulmonary embolism (12.44%). The 5-year survival-rate for patients under 60 years was 31%.

Two cases of pneumatosis cystoides intestinalis (PCI), apparently of different etiologies, were found at autopsy in cancer patients. One case was associated with chronic obstructive lung disease and with emphysema of soft tissues of the mediastinum, retroperitoneum, and mesentery, whereas the other showed pseudomembranous enteritis with bacterial and fungal overgrowths. The latter case supports the role of gas-forming bacteria, while the former provides an anatomical evidence of pulmonary disease as a cause of PCL. Obstruction of the upper gastrointestinal tract may contribute to the occurrence of PCI by a complication of aspiration pneumonitis or disturbance of the normal bacterial flora of the intestine as well as an increase of the intraluminal pressure. In addition to the etiologic considerations, the importance of clinical diagnosis of PCI has been emphasized since both cases in the present report were more or less related to the cause of death.

In a 22-year followup of 3686 San Francisco longshoremen, the roles of physical activity, cigarette smoking habit, and systolic blood pressure level were evaluated independently in relation to risk of death from a broad range of diseases. Smoking pattern and blood pressure status were established in 1951 and job activity was assessed annually during the followup period. Lower levels of energy expenditure predicted increased risk of fatal heart attack and perhaps of stroke. Heavy cigarette smoking predicted increased risk of death from heart attack, cancer, chronic obstructive respiratory disease, and pneumonia. Higher levels of systolic blood pressure were associated with death from all cardiovascular diseases, diabetes mellitus, and cirrhosis. Tacit to these findings: sedentary living takes its toll largely through heart disease and stroke; the toxicity of cigarette smoking is associated with a broader range of diseases, including heart attack, cancer, and respiratory disease; and higher level of blood pressure related to an even broader range of cardiovascular disease than either of the other characteristics studied.

Between April 1969, and December 1974, 111 consecutive surgically staged I A and II A patients with supradiaphragmatic Hodgkin's disease were treated at the Joint Center for Radiation Therapy. Patients received 3600--4400 rad to mantle and para-aortic--splenic pedicle regions. Median follow-up was 56 months (30--96). Fourteen patients developed relapsing Hodgkin's disease and three patients died of possible treatment-related causes, two with acute myocardial infarctions and one with radiation pneumonitis. Patients with mediastinal enlargement greater than one third of the chest diameter have a significantly higher risk (p less than 0.01) of developing relapse (9 of 18) than patients with lesser or no mediastinal disease (5 of 93). Of the 18 patients with large mediastinal disease, six relapsed in the mediastinum and two in the lung. There continue to be no pelvic extensions in the entire group. There is a 92% relapse-free and 97% overall survival in the 93 patients without extensive mediastinal disease. We continue to recommend mantle and para-aortic--splenic pedicle irradiation for these patients. In view of the large number of relapses in patients with extensive mediastinal disease, we are now treating this subgroup of patients with MOPP chemotherapy in addition to mantle and para-aortic irradiation.

Air quality correlates of chronic disease mortality in 180 census tracts of Harris County, Texas, were studied using 3 years mortality for 1969--1971. This study was designed to test with a different data base the universality of several study results which have reported significant correlations between heart disease and air pollutants. Air quality data (suspended particulates, benzene solubles, sulfur dioxide, and metals associated with particulates: copper, mercury, manganese, lead, nickel, zinc, chromium, and cadmium) were related to both sex and age adjusted crude death rates, and cause-specific death rates for age cohorts for 7 categories of heart disease, and pneumonia, asthma, cancer, tuberculosis, and accident deaths. The results of the study were in agreement with the findings of the other researchers who used national data. Suspended particulates and cadmium concentrations were found to be correlated (r=.38, .36; P less than .001) with ischemic heart disease (IHD). Many other significant correlations are reported but are not cause-specific. Socio-economic indicators were also correlated with IHD, thus confounding the issue. Further work is planned using more sophisticated statistical techniques to disentangle the relative contribution of each of these highly intercorrelated factors. No causality can be assigned at this stage, although this study, with the other cited, points to possible risk factors for IHD which need further evaluation.

Gentamicin in combination with cephalothin (Gent-Ceph) or with chloramphenicol (Gent-Chloro) was utilized in the treatment of 55 infections occurring in 49 cancer patients. Responses were obtained in 78% of the infections treated with Gent-Ceph and in 64% of those treated with Gent-Chloro. Pneumonia and septicemia were the most common infections in this study. Among the cases of penumonia, 64% responded to Gent-Ceph and 67% to Gent-Chloro. Among the cases of septicemia, 88% responded to Gent-Ceph and 50% to Gent-Chloro. All of the identified organisms producing infection were gram-negative bacilli. Of these, E. coli was the most common. All organisms were resistant to cephalothin in vitro, and only 41% of them were resistant to chloramphenicol. However, resistant organisms responded significantly better to the Gent-Ceph combination (p less than 0.025). Also, response to therapy among patients with severe neutropenia (less than 100 neutrophils/mm3) was better for those patients treated with Gent-Ceph (p = 0.07). The combination of gentamicin with cephalothin or with chloramphenicol did not increase the frequency of side effects expected from gentamicin alone. No significant hematological toxicity was seen among those patients treated with chloramphenicol. Gentamicin in combination with cephalothin or chloramphenicol is an effective and safe antibiotic combination against gram-negative bacilli infections occurring in cancer patients. The efficacy of Gent-Ceph in patients with severe neutropenia is particularly advantageous.

A total of 102 studies were conducted on 89 patients receiving cancer chemotherapy while on a protected environment-prophylactic antibiotic program. Major infections occurred during 22 studies. The majority of both minor and major infections originated during the first five weeks after the patients entered the protected environment units. The frequency of infectious complications was inversely related to the circulating neutrophil count. The majority of infections were cases of cellulitis, pharyngitis, pneumonia and septicemia. Most of the infections were caused by gram-negative bacilli. The majority of organisms causing infection had persisted in the patients after their entry into the protected environment units despite the use of prophylactic antibiotics.
