Registered deaths from the vital statistics registration system of Lagos City, a system that was judged to be 60% complete, were analyzed for the year 1977. Nearly 40% of total registered deaths were from infections, parasitic diseases, and motor vehicle accidents. Of the reported deaths, 17.3% were from ill-defined conditions. Deaths from neoplasms, diseases of the nervous and sense organs, diseases of the digestive and genitourinary systems as well as those from congenital anomalies are relatively less frequent. Maternal mortality appears to be very high. The age pattern of mortality is different from that in the developed countries, a high proportion of the deaths in Lagos being those of children aged under 5 years. Infant mortality is dominated by perinatal causes which constituted a huge 38.4% of deaths of infants under 1 year, the other important causes being dysentery and diarrhea, pneumonia, and tetanus. Among adults, death from motor vehicle accidents is the most important cause accounting for more than 26% of deaths in the age group 15 years and above. Other important causes of adult deaths are cerebrovascular disease, hypertensive disease, heart disease, pneumonia, dysentery and diarrhea, and complications of pregnancy. Well organized health services stressing antenatal care, preventive and health education services are needed to effect a reduction in mortality and bring about a general improvement in the health of the people.

Infections of the central nervous system in patients at risk are relatively uncommon when compared with pneumonia, bacteremia, and soft tissue infection. However, they carry serious morbidity and are frequently fatal. Each of the diverse conditions that can place a patient at risk for central nervous system infection is associated with a fairly predictable spectrum of etiologic organisms. Various forms of trauma (including blunt and penetrating injuries and neurosurgery, especially when a cerebrospinal fluid shunt is implanted) predispose to infection with common pathogenic bacteria. Defects of cellular immunity including congenital immune deficiencies, immunosuppressive drug therapy, leukemia, lymphoma, and the acquired immune deficiency syndrome are more likely to give rise to infection with a distinctive spectrum of opportunistic viruses, fungi, and protozoa. Other underlying conditions include sinus, ear, and mastoid infections, congenital heart disease, intrathoracic suppuration, endocarditis, and bacteremia, hypogammaglobulinemia, and complement deficiencies. Some preventive measures including vaccines, antibiotics, and surgical procedures are available. However, for many of these central nervous system infections, preventive measures are lacking or less effective than those for infections in other organs. In the future, opportunistic central nervous system infections will increase in frequency as the number of patients at risk continues to grow.

As part of a systematic program to evaluate the late effects of antineoplastic therapy in randomized clinical trials, patients enrolled in the low-dose thio-TEPA (TSPA) and 5-fluoro-2'-deoxyuridine (FdUrd) adjuvant colorectal cancer protocols of the Veterans Administration (VA) Surgical Oncology Group between 1958 and 1964 were studied. All patients received surgery with curative intent; 470 also received TSPA, 176 received FdUrd, and 867 received surgery only. The unique VA system permitted complete follow-up through 1977, with 10,902 person-years of observation accrued among 1,613 male patients (mean survival = 6.8 yr). Expected mortality and cancer incidence were computed by applying U.S. Mortality Statistics and Connecticut Tumor Registry age-, race-, sex-, and calendar time-specific rates to the person-years of observation. The mortality experience of the 3 groups was similar. Overall, there was a significant excess in total mortality (observed/expected = 1,359/553) attributable mainly to colorectal cancer (584/14), arteriosclerotic heart disease (258/215.9), pneumonia (41/17), gastric and duodenal ulcers (15/4), and cirrhosis (14/6). No excess mortality from noncolorectal cancers was apparent, nor were there significant differences by treatment: TSPA (22/22), FdUrd (9/12), and surgery only (50/42). Among 1,402 white patients, no significant excess of incident noncolorectal cancers were observed among patients treated with TSPA (30/31, FdUrd (14/15), or surgery only (63/58). Seven incident cases of leukemia developed (4.1 expected) among all patients of various groups: TSPA (3/1.3), FdUrd (1/0.6), and surgery only (3/2.2). No excess of new primary cancers was observed among 211 nonwhite patients. An inverse relationship between the occurrence of second primary cancer and age at diagnosis, irrespective of therapy, was suggested. The results demonstrated the feasibility of this approach for assessment of late complications of anticancer therapy and suggested no measurable carcinogenic effect following very low doses of TSPA and FdUrd in a population of this size.

The mortality rates (MRs) of children under 5 years of age in the various population groups of the RSA were calculated as deaths/10(5) for various causes of death and groupings of causes of death as classified by the International Classification of Diseases. In 1970 the ten leading causes of death among Coloured and Black children under 5 years of age in the RSA were similar to those among children in developing countries. The rank order of causes of death (in MRs/10(5] among Coloured children was as follows: gastro-enteritis (1 733), pneumonia (725), immaturity (405), ill-defined causes of death (168), nutritional deficiencies (167), measles (126), anoxia (97), 'other bacterial diseases' (91), inflammatory diseases of the nervous system (55) and tuberculosis (48). The ten leading causes of death among White children in the RSA were characteristic of children in Western developed countries. The rank order (in MRs/10(5] was as follows: immaturity (144), anoxia (94), pneumonia (46), gastro-enteritis (41), congenital heart disease (32), other accidents (19), birth injury (19), ill-defined causes of death (12) and inflammatory diseases of the nervous system (11).

To examine mortality risks for farm laborers proportional mortality ratios (PMRs) were calculated for 2,328 British Columbia farm workers who died at age 20 years or over during the period 1950 through 1978. Significantly fewer deaths than expected from degenerative heart disease (PMR = 91, p less than .01) and from all cancers combined (PMR = 78, p less than .001) were observed. Deaths from bronchitis and emphysema (PMR = 70, p less than .05) were also fewer than anticipated. Elevated risks of death were found for accidents (PMR = 129, p less than .001), for homicide (PMR = 242, p less than .01), and for pneumonia (PMR = 146, p less than .001).

Pulmonary edema is an important feature of many newborn lung diseases, including respiratory distress from severe perinatal asphyxia, heart failure, hyaline membrane disease, pneumonitis from group B beta-hemolytic streptococcus, and chronic lung disease (bronchopulmonary dysplasia). Neonatal pulmonary edema often results from increased filtration pressure in the microcirculation of the lungs. This occurs during sustained hypoxia, in left ventricular failure associated with congenital heart disease or myocardial dysfunction, following excessive intravascular infusions of blood, colloid, fat, or electrolyte solution, and in conditions that increase pulmonary blood flow. Low intravascular protein osmotic pressure from hypoproteinemia may predispose infants to pulmonary edema. Hypoproteinemia is common in infants who are born prematurely. Large intravascular infusions of protein-free fluid further decrease the concentration of protein in plasma and thereby facilitate edema formation. Lymphatic obstruction by air (pulmonary interstitial emphysema) or fibrosis (long-standing lung disease) also may contribute to the development of edema. Bacteremia, endotoxemia, and prolonged oxygen breathing injure the pulmonary microvascular endothelium and cause protein-rich fluid to accumulate in the lungs. The risk of neonatal pulmonary edema can be reduced by several therapeutic measures designed to lessen filtration pressure, increase plasma protein osmotic pressure, and prevent or reduce the severity of lung injury.

The type distribution of pneumococci isolated from 462 patients was determined. In this survey type 1 strains were the most numerous but type 14 and type 18 caused the most infections in children under five years of age. The most common infections were pneumonia, meningitis or septicaemia. Possible pre-disposing causes included a history of heavy drinking, head injury, bronchitis or other chest infection, heart disease, liver disease, malignancy, viral infection or abnormality of the spleen.

Pulmonary edema is an important cause of respiratory distress in newborn infants. It occurs with severe perinatal asphyxia, heart failure, hyaline membrane disease, persistent patency of the ductus arteriosus, pneumonitis from group B beta-hemolytic streptococcus, and chronic lung disease (bronchopulmonary dysplasia). Neonatal pulmonary edema often develops from increased pressure in the microcirculation of the lungs. This may occur in conjunction with sustained hypoxia; left ventricular failure associated with congenital heart disease or myocardial dysfunction; following excessive intravascular infusions of blood, colloid, fat, or electrolyte solution and in conditions that increase pulmonary blood flow. Low intravascular protein osmotic pressure from hypoproteinemia may predispose infants to pulmonary edema. Hypoproteinemia is common in infants who are born prematurely. Large intravascular infusions of protein-free fluid further decrease the concentration of protein in plasma and thereby facilitate edema formation. Lymphatic obstruction by air (pulmonary interstitial emphysema of fibrosis (chronic lung disease) also may contribute to the development of edema. Bacteremia, endotoxemia, and prolonged oxygen-breathing injure the pulmonary microvascular endothelium and cause protein-rich fluid to accumulate in the lungs. Epithelial protein leaks may develop when the transpulmonary pressure needed to inflate the lungs increases because of high surface tension at the air-liquid interface. Fibrin clots from in some of the air spaces, which in combination with atelectasis and edema constitute the pathologic features of hyaline membrane disease. The risk of neonatal pulmonary edema can be reduced by several therapeutic measures designed to lessen fluid filtration pressure, increase plasma protein osmotic pressure, and prevent or reduce the severity of lung injury.

Twenty-four-hour ambulatory electrocardiography was performed in 25 young and 29 active elderly subjects. Sinus bradycardia and sinus arrhythmia were common in the young but uncommon in the elderly. Ventricular and supraventricular premature beats and brief runs of supraventricular tachycardia were common in the elderly but uncommon in the young. Complex ventricular arrhythmias only occurred in the elderly but brief episodes of nocturnal Wenckebach AV block were quite common in young and old alike. No significant difference in arrhythmia frequency was found between elderly subjects with heart disease and those without heart disease or between elderly subjects without symptoms and those with non-episodic symptoms such as dizziness. None of the arrhythmias in the young or elderly subjects was associated with symptoms. In follow-up at 30 months, only one elderly subject was deceased (from pneumonia) and none had suffered a stroke or heart attack. It is concluded that transient cardiac arrhythmias are commoner in the elderly than in the young. However, their long-term significance remains unknown, but it is likely that they are relatively benign.
