The causes of death in 130 patients with Down's Syndrome and mortality rates from a material of 524 patients were tabulated; a life-table for the ages over 5 years was constructed. An overall death rate of 5-7 times the general population rate was found. No sex difference was observed. The excess mortality was expecially high for heart disease and respiratory disease. Also infectious diseases, others than pneumonia and tuberculosis, showed high mortality rates.

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.

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.

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.

The indices of P a-A CO2, P A-a O2 and VD/VT were evaluated in a group of children treated with controlled ventilation (IPPV) for: pneumonia, congenital heart disease, respiratory distress syndrome or central nervous system diseases. The P A-a O2 index is regarded as the most useful one, since it enables the possibility to select a F IO2 value for obtaining an optimal P aO2. For calculation of VD/VT according to Bohr's formula during connection of the child to respirator P ECO2 was determined planimetrically from the capnographic curve. P a-A CO2 was recognized as a less useful index and difficult to interpret.

One hundred and fifty lungs from the cases below 15 years of age with various congenital heart diseases and 80 controls were used for histometrical and histological studies. Cases with congenital heart disease were divided into two groups of the increased and the decreased pulmonary blood flow. In the former group, the thickness of the pulmonary arterial media was the same as that of controls in the neonatal period, and through the wall thickness gradually decreased in a pattern seen in controls, the thickness was constantly larger than that of controls. In some cases, the media increased gradually within 6 months after birth. Pneumonia and massive pulmonary hemorrhage were seen in a higher incidence in autopsy cases. Pneumonia in younger infants was histologically characteristic and possibly more correlated to their death. In the latter group, most of the cases were with the thinner medias of the pulmonary arteries. Massive pulmonary hemorrhage was not common in the latter group.

A clinical efficacy study of amikacin in the treatment of 15 adults with nonbacteremic, gram-negative bacillary pneumonia is presented. All patients had serious underlying illnesses (11 organic heart disease, five chronic obstructive pulmonary disease, one cancer); 11 had undergone major surgical procedures. All had required respiratory assistance during their hospitalization and all had recently received other antibiotics. Thirteen of 15 patients showed clinical improvement with amikacin therapy; the pathogen was also eradicated in 10 of the 13. The mean minimum inhibitory concentration of amikacin for the 17 isolated pathogens was 3.13 microng/ml. The mean peak serum concentration of amikacin was 17.7 microng/ml. No evidence of ototoxicity or nephrotoxicity was seen. Seventy-three case reports submitted to the manufacturer by multiple investigators of patients with gram-negative pneumonia, treated with amikacin, are also reviewed. All isolated pathogens were sensitive to both amikacin and gentamicin. Fifty-four (74%) of these patients showed improvement with amikacin therapy.

In the Tri-State Leukemia Survey, the history of diseases in 605 adult male leukemia cases 15 years and older and in 668 adult male population controls was examined. These diseases occurred at least 1 year before leukemia was diagnosed. The data were based on respondents' answers that the disease was diagnosed by a physician; the respondent was either the subject or his spouse. Of 30 diseases studied, 7 showed an excess among the patients with leukemia: infectious hepatitis, eczema, psoriasis, diabetes, arthritis and rheumatism, heart disease, and ankylosing spondylitis. Mumps had a lower reported occurrence among the cases, whereas pneumonia was less frequent in acute lymphatic cases than in population controls. Three diseases occurred significantly less in controls than in persons with specific histologic types of leukemia. Our data revealed a more frequent history of herpes zoster (shingles) in chronic lymphatic leukemia, more hives in acute chronic myeloid cases, and meningitis in acute myeloid leukemia. When we only considered the patients' responses, more of them admitted having had acne than did our controls. The remaining diseases--childhood viral diseases, infectious mononucleosis, smallpox, typhoid fever, dysentery, scarlet fever, tuberculosis, asthma, hay fever, and goiter did not occur more frequently in cases than in controls. The findings were consistent with evidence from previous laboratory and clinical studies. The increased occurrence of infectious hepatitis in our case series is consistent with the findings of other studies showing an increased frequency of Australia antigen in patients with hepatitis, leukemia, and Down's syndrome.

As a result of findings of an earlier report in this series, this study examines the updated cause-specific mortality of men employed in the sheet and tin mill areas of the steel industry. In order to investigate possible relationships between occupational responsibilities or exposures and mortality from specific causes, the sheet and tin mills have been subdivided into 13 mutually exclusive work areas. Detailed analysis is limited primarily to white workers due to the small number of nonwhites in these areas. The most important observations are: 1. Increased overall mortality appears for men employed in 1953 in the sheet finishing and shipping area, confirming the findings of Lloyd, et al. The earlier observation of a significant excess in deaths from vascular lesions of the central nervous system does not hold over time. The previously noted excess for this cause may be related to selective factors or an extreme chance observation. The excess in mortality from all causes of death, which occurs over several disease categories, may not be a result of occupational exposures, but rather some selectivity. 2. Significant excesses in mortality from arteriosclerotic heart disease are noted among men employed in batch pickling and sheet dryer operations, which is in agreement with the earlier findings. Increased risks of dying from hypertensive heart disease are seen in the coating area. 3. Cancer of the lymphatic and hematopoietic tissues is found to be a significant source of excess mortality for workers in the heat treating and forging and tin finishing and shipping work areas. 4. Steelworkers employed in the annealing-normalizing work area show an excess in deaths from nonmalignant respiratory diseases, primarily pneumonia. Further study in these areas should attempt to investigate whether factors in the work environment may be responsible for the observed excess mortalities. More specifically, work should be done to find out whether men employed in heat treating and forging and tin finishing and shipping work in close proximity to chemicals or radiation exposure and whether workers employed in the annealing-normalizing area are exposed to any kind of oil, vapor, or chemical which might be irritating or infectious to the respiratory system. A similar analysis for men working in the batch pickling and sheet dryers and coating areas would also be worthwhile. The main emphasis of any future study should lie upon investigating whether the observed excess mortalities are due to any environmental factor, selection for health, or random fluctuation.

In order to facilitate for the general physicians the making of a suitable selection of babies who are in the most urgent need of specialized treatment at cardiac centres, simple methods for diagnosing and qualifying congenital cardiovascular diseases were elaborated. The following "minor" criteria were taken for suspecting a CHD: 1) cardiorespiratory distress following birth, 2) sequentially repeated Apgar score below normal, 3) "pneumonia" symptoms with respiratory distress, dyspnoea and cyanosis, attacks of unconsciousness, 4) feeding difficulties, failure to thrive, inexplicable irritability, 5) presence of other congenital anomalies. The almost certain presence of serious heart disease should be recognized in children, showing the following "major" symptoms: 1) permanent cyanosis, pallor or greyish colour, 2) cardiorespiratory failure (resembling usually symptoms of pneumonia), 3) ECG patterns indicating ventricular hypertrophy signs, 4) other significantly abnormal ECG patterns (e.g. AV and intraventricular conduction disturbances), 5) cardiac enlargement and lung vascularity abnormalities in chest X-rays, 6) weak, or impalpable arterial, particularly femoral pulses, femoral arterial pressures significantly lower, than at upper extremities, bounding pulses and high-pressure amplitude in arms and legs, 7) abnormal heart sounds and pathologic heart and vascular murmurs. A diagnostic "key", based upon evaluation of the "major criteria" facilitates the diagnosis and differentiation of the most important CHD's at neonatal and infantile age. When using this "key" one should keep in mind the relative frequency of incidence of particular lesions. The initial diagnoses by the above "key" were verified in 354 patients by cardiovascular catherisation, angiocardiography, surgical exploration, and for by autopsy. The diagnoses were perfectly accurate in 83.6% cases, in further 11.3% cases being also accurate but were supplemented by some details, and had to be corrected in only 5.1% cases.
