Bacillus thuringiensis var. israelensis (B.t.i.) is a promising, safe toxic agent for control of mosquitoes, but the rapid disappearance of its toxicity makes its use in practice economically unattractive. The lack of evidence for B.t.i. multiplication in water also makes the natural ecology of B.t.i. puzzling. The observation that mosquito ...

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 ...

Ninety-three asthmatic patients were examined on 320 occasions for wheezing and peak expiratory flow rate (PEFR). The presence of a wheeze (either reported by the patient or found on examination) was associated with a significantly lower PEFR. Expiratory wheezing was usually accompanied by inspiratory wheezing; this biphasic wheezing was associated ...

Strychnine poisoning results in a predictable and treatable sequence of events involving blockade of the inhibitory neurotransmitter, extensor muscle spasms, seizures, and respiratory paralysis. These spasms may lead to hyperthermia, profound lactic acidosis, and rhabdomyolysis. Acidosis is primarily attributable to lactate, as indicated by the correlation between arterial pH and ...
