Co-administration of intravenous albuterol and theophylline resulted in increased theophylline clearance in a child with severe asthma. This required a threefold increase in theophylline dosage to maintain therapeutic serum theophylline concentrations. The possible effect of intravenous albuterol on theophylline metabolism was further supported by a 50 percent decrease in theophylline ...

A ten-year longitudinal study of all civil commitments was conducted in a mid-sized county in Washington State, beginning with the 1974 effective date of a more stringent commitment law and encompassing the introduction of more lenient criteria five years later. A major finding was the increase in the number of ...
Siegel S C - - 1987
Death from asthma has been known to occur since its original descriptions in ancient times. Even in the eighteenth century some risk factors for death, such as delayed or inadequate treatment, were recognized. Autopsies performed on some patients dying of asthma in the seventeenth and eighteenth centuries did not show ...
Bousquet J - - 1987
Deaths caused by asthma are now recognized in all western countries, but they were only lately accepted in France because Laennec and Trousseau denied that patients with asthma may die of asthma. The "epidemic" of asthma deaths of the 1960s was not observed. Since 1968, it appears that asthma deaths ...
Tan C T - - 1987
This study presents the pattern of suicidal poisoning deaths in Singapore for 1975 to 1984. A total of 282 suicidal poisoning deaths investigated at the Department of Pathology were retrospectively analysed. It was found that for the ten year period, death by poisoning was the third most popular method of ...

Susceptibility of the leishmaniasis vector sandfly Phlebotomus papatasi (Scopoli) to three insecticides was assessed on a colony originating in the Jordan Valley, Israel. Results are considered to show susceptibility to DDT and permethrin. The results for methoxychlor indicated the possibility of heterogeneity in the population and tolerance towards this compound.
Esdaile J M - - 1987
The 1960s epidemic of asthma deaths that affected young persons in England and Wales, as well as in other countries, was attributed to the effect of newly available pressurized aerosols containing sympathomimetic bronchodilators. The subsequent decision to ban the nonprescription sale of these agents in the United Kingdom represented a ...
Panter K E - - 1987
Approximately 250 sheep were poisoned and died from ingesting death camas (Zygadenus paniculatus) within a 2-day period on a foothill range in southeastern Idaho. Sixty to 70% of the poisoned sheep were 80-90 lb lambs and the rest were mature ewes. Poisonings were confirmed by field investigation, microhistological analysis of ...
Onyon L J - - 1987
In the UK there was an increase in the annual number of deaths associated with paraquat poisoning between 1966 and 1975. Since that time there has been little change in numbers. High mortality is associated commonly with suicidal intent. Serious accidental poisoning from paraquat has never been frequent in the ...
Toyoshima K - - 1987
Forty-eight wheezy infants were followed up for 25 to 44 months. These infants were classified into three groups: those with asthma (developed asthma later), the wheezy group (had successive wheezing episodes), and the non-wheezy group (grew out of the wheezy episodes). Serum IgE levels at the first visit were not ...

The epidemic of deaths from bronchial asthma in New Zealand was investigated by a two-year national review of all deaths of persons under 70 years where "asthma" appeared in part I of a death certificate or in a coroner's report of cause of death. Information about the patients, the characteristics ...
Tyler J W - - 1985
Wet nappies at night could cause infants at risk to die. Tyler first suspected this ten years ago when his head was jerked back from his infant son's cot by the pungent odour of ammonia gas. This theory is consistent with the full epidemiology of cot-death. Ammonia is an insidious ...
Sutherland D C - - 1984
New Zealand has experienced an epidemic of asthma deaths since 1977 with mortality rates of over 3.0/100 000 for people aged 5-34 years, more than three times the rate of comparable countries. To examine the reasons for this high mortality rate all deaths from asthma in people under 70 years ...
Roland E H - - 1984
Two infants presented with fever and signs of brainstem dysfunction, including impaired consciousness, miosis, absence of oculocephalic responses, respiratory depression and a very peculiar tremor of the tongue and floor of the mouth. They were found to have methadone poisoning caused by accidental contamination of prescribed antibiotics in the same ...

The results of a metrical analysis of the basicranium of 19 Plio-Pleistocene fossil hominid crania are presented. The sample includes crania attributed to Australopithecus africanus, Australopithecus boisei, and robustus, and Homo erectus as well as crania whose attribution is still under discussion. These results confirm significant differences between the cranial ...
Pearl M - - 1980
Because lead crosses the placenta throughout pregnancy, the fetus is at risk for lead poisoning. A full term, asymptomatic child was born with congenital lead poisoning secondary to maternal pica. Radiographic findings of a dense cranial vault, lead lines, and delayed skeletal and deciduous dental development were noted at birth. ...
Ormerod L P - - 1980
Out of 83 patients studied 72 were certified as dying from asthma, and 11 aged under 45 as dying from chronic bronchitis and pneumonia. Fifty-three deaths were thought to be due to asthma. There were avoidable factors associated with several of these deaths from asthma. Recent discharge from hospital (16%), ...
