In recent years health professionals have been concerned about the health of aborigines which has been neglected for a long time. Health disparities are known to exist among aborigines and non-aborigines in the United States or other countries. In Taiwan, there are nine main aboriginal tribes consisting of approximately 330,000 people. In general, their health status, evaluated by life expectancy, mortality rates and the prevalence and incidence of various diseases amongst them, is worse than amongst the rest of the Taiwanese (general) population. Current investigations indicate that life expectancy for aborigines is on average 10 years less than that of the general population; 12.5 years less for men, 6 years less for women; approaching a standardized mortality ratio of 2 fold, that is 2.1 fold in men, 1.7 fold in women. Accidental injures, suicide, tuberculosis, liver cirrhosis, alcoholism, pneumonia, bronchitis, parasite infections are the most important sources of diseases. Hypertension, heart disease, some selected sites of cancer, nutrition and lack of adaptation are gradually becoming important new sources of disorders. Although aboriginal health has improved over the decades, the author estimates that their overall health status is 25-30 years behind that of the general population or of off-shore islanders. The extent of their development varies with tribes. It is necessary to study the cause of why aborigines die so young. It may be due to insufficient medical care for heart disease whose prevalence is relatively low among aborigines but resultant mortality is nevertheless high. However, insufficient medical care cannot explain the high incidence of a number of cancers and resultant mortality. All factors relating to the environment, agents, hosts and diseases should be taken into consideration, such culture, transportation, life style, health behavior etc, and compared to those of non-aborigines. A series of studies are proposed to address the specific, multi-dimensional health demands of the aborigines. The author suggests the development of prevention and intervention strategies designed to overcome difficulties and barriers to eliminate these disparities among the people of Taiwan.

To update the clinical profile of pediatric patients hospitalized with RSV infection, we retrospectively reviewed the records of 246 children (male:female ratio 1.44:1) admitted during one season to a tertiary-care hospital. The most common admitting diagnoses were bronchiolitis (37.4%), pneumonia (32.5%), and possible septicemia (13%). Median age was 3 months; median length of stay, three days. Twice as many minorities were admitted with RSV infection as all other admissions during the same year. Family history of asthma, while common (35%), did not affect length of stay or complications. Of the 38 (15%) patients requiring intensive care, 29 (76%) underwent ventilation. Patients with underlying cardiopulmonary disease had more complications, were more likely to require intensive care (about 50%), and had significantly longer hospital stays than others. All three patients (1.2%) who died had congenital heart disease. Common risk factors included young age, chronic cardiopulmonary disease, male sex, and possibly family history of asthma. Although the most typical clinical diagnoses remain bronchiolitis and pneumonia, a systemic illness resembling the sepsis syndrome has emerged at our institution as a significant clinical presentation.

During late December 1989 and early January 1990, a cluster of six unexplained deaths occurred on a paediatric intensive care unit (PICU) among children with congenital heart disease who had undergone cardiac surgical procedures. The children were all aged three years or less. In each case death was preceded by an unexpected increase in ventilatory pressure requirement followed by the development of a similar pulmonary shadowing on chest radiography. The radiological abnormality was felt to be consistent with a pneumonitis associated with some small airway disease. The clustering of these deaths, occurring in a similar unusual manner, was felt to constitute an outbreak warranting investigation. An Incident Committee was established to plan and manage a large multidisciplinary investigation during which the unit was temporarily closed. Following extensive investigation no bacterium, virus, fungus or other pathogen, toxic agent, or any other explanation for the cluster of deaths could be found. The possibility that the cluster occurred by chance remains although this was felt to be unlikely.

The air pollution disasters in London in 1952, the Meuse valley in 1930, and in Donoroa, Pennsylvania, in 1948 made it clear that extremely high levels of particulate-based smog could produce large increases in the daily mortality rate. Recent studies of fluctuations in daily air pollution and daily mortality have reported associations at much lower concentrations in London during the 1960s and in Philadelphia, Steubenville, Santa Clara, St. Louis, Utah valley, Detroit, and eastern Tennessee in the 1970s and 1980s. Whether these associations are causal or not is a matter of considerable public health concern. If the detailed pattern of the deaths at these lower concentrations appeared similar to the pattern in London, this would strengthen the argument for causality. To examine this issue, the death certificates from Philadelphia were examined on the 5% of the days with the highest particulate air pollution and the 5% of the days with the lowest particulate air pollution during the years 1973-1980. There was little difference in weather between the high and low pollution days, but total suspended particulate matter concentrations averaged 141 micrograms/m3 on the high pollution days versus 47 micrograms/m3 on the low pollution days. The relative risk of dying on the high pollution days was 1.08 P < 0.0001. The relative increase was higher for COPD (1.25) and pneumonia (1.13). Deaths were also elevated for heart disease and stroke; however, there was a substantial increase in the reports of respiratory factors as contributing causes for those underlying causes of death. Dead-on-arrival deaths and deaths outside of hospitals and clinics were also disproportionately increased. This paralleled the pattern seen in London in 1952. The age pattern of the relative risk of death was also similar. This adds to the evidence that the association is causal.

Correlates of the size of infarcts, the time from stroke to death, and the mechanisms of death were studied in 77 consecutive patients who died from infarction in the middle cerebral artery territory. The area of infarcts was assessed by planimetry on schemas of representative brain levels and the results were expressed as a ratio of infarcted area on the whole MCA territory. No clear relationship was found between the size of infarcts in the MCA territory, and any of the characteristics of the patients, but extensive infarcts were more frequent when the internal carotid artery was occluded. No evidence was found of an adverse effect of age, diabetes or initial hyperglycemia on the size of infarcts. The mechanisms of death were not linked to sex, age, high blood pressure, diabetes, blood glucose level at admission, presence and location of an arterial occlusion, or etiology of the infarct. On the contrary, they varied as a function of interval from stroke to death. Transtentorial herniation, the main cerebral cause of death, occurred mainly in the first week and was related to the large size of infarcts. Rare recurrences of stroke and frequent extracerebral mechanisms of death (mainly pneumonia, pulmonary embolism and cardiopathy) occurred later on.

A study of 9,135 persons injured between 1973 and 1984 and treated at any of 13 regional spinal cord injury care systems was conducted to compare their age-, sex-, race-, and cause-specific mortality rates with those of the general population. All subjects survived at least 24 hours. Follow-up was terminated in December, 1985 when 854 persons (9.3%) had died. Although many persons had multiple causes of death, the leading primary causes were pneumonia, nonischemic heart disease, septicemia, symptoms and ill-defined conditions, pulmonary emboli, and ischemic heart disease. During the study period, spinal cord injured persons were 82.2 times more likely to die of septicemia, 46.9 times more likely to die of pulmonary emboli, and 37.1 times more likely to die of pneumonia than comparable individuals from the general population. Though some cause-specific mortality rates for spinal cord injured persons have declined dramatically, many remain substantially above normal. Before life expectancies increase further, improved methods for preventing and managing these fatal complications must be developed.

This paper reviews the common spectrum of medical diseases of the neonatal chest. Emphasis is on radiographic changes that have been produced by the introduction of new therapeutic maneuvers, particularly the use of artificial surfactant in treating hyaline membrane disease and the survival of profoundly premature newborns (less than 650 g). A discussion of meconium aspiration syndrome, neonatal pneumonia, transient tachypnea of the newborn, congenital lymphangiectasia, and congenital heart disease is also included. The effects on the neonatal chest radiograph of extracorporeal membrane oxygenation and high-frequency ventilation are also mentioned.

Between 1976 and 1992, 32 patients aged 75 and older with stage I-II non-small cell lung cancer (NSCLC) were given definitive radiation therapy. These patients did not undergo surgery because of old age, poor cardiac/pulmonary condition, or refusal to give consent. The mean age was 79 years, and 11 patients were over 80 years old. The histologic type was squamous cell carcinoma in 25 patients and adenocarcinoma in 7. The clinical T and N stage was T1N0 in 4 patients, T2N0 in 9, and T2N1 in 19. The total dose of radiation therapy given to each patient exceeded 60 Gy using 10-MV X-rays. The treatment was completed in all 32 patients without treatment-related complications. The 2- and 5-year overall actuarial survival rates wer 40% and 16%, respectively. Eleven intercurrent deaths occurred, including 7 patients who died of heart disease. The 2- and 5-year cause-specific survival rates were 57% and 36% respectively. None of the patients developed severe pneumonitis requiring hospitalization. All but three patients received radiation therapy on an inpatient basis. The mean duration of the hospital stay for initial treatment was 56 days, and mean ratio to total survival period (mean 739 days) was 8%. Although many elderly patients have concurrent medical complications such as heart disease and chronic pulmonary disease, the present study showed that elderly patients with clinical stage I-II NSCLC can expect a realistic probability of long-term survival with definitive radiation therapy.

The detailed mortality and morbidity statistics on smoking tend to conceal the overall impact of the habit on health. About 3 million people die each year from smoking in economically developed countries, half of them before the age of 70. Cancers of eight sites are recognized as being caused by smoking--lung cancer almost entirely and the others (upper respiratory, bladder, pancreas, oesophagus, stomach, kidney, leukaemia) to a substantial extent. Six other potentially fatal diseases are also judged to be caused by smoking: respiratory heart disease, chronic obstructive lung disease, stroke, pneumonia, aortic aneurysm and ischaemic heart disease, the most common cause of death in economically developed countries. Non-fatal diseases, such as peripheral vascular disease, cataracts, hip fracture, and periodontal disease, which cause appreciable disability, cost and inconvenience are also caused by smoking. In pregnancy, smoking increases the risk of limb reduction defects, spontaneous abortion, ectopic pregnancy, and low birth weight. While there are some diseases for which smoking shows a protective effect, the 'benefits' of these are negligible in relation to the illness and premature mortality caused by smoking. About 20% of all deaths in developed countries are caused by smoking; an enormous human cost which can be completely avoided.
