Identity cards for patients infected with HIV?

Dr A C Srivastava has written to us to describe a case that raises the suggestion that people infected with the human immuno-deficiency virus (HIV) should carry identity cards. We asked two physicians, a general practitioner working with patients with the acquired immune deficiency syndrome (AIDS), and a general practitioner with a special interest in medical ethics to respond to the broad issues raised by Dr Srivastava''s letter.     

Strongyloidiasis in Canadian Far East war veterans

A survey was done of Canadians who had been interned by the Japanese during World War II to assess the prevalence of latent infection with Strongyloides stercoralis in this group. Packages containing three mail-in kits and a questionnaire were sent to 992 men, 694 (70%) of whom responded. Larvae were found in the stool specimens of four of the respondents. Examination of stool specimens after formalin-ether concentration was the most successful method of detecting Strongyloides larvae. The Baermann concentration technique yielded negative results in all four men. Three of the four cases of strongyloidiasis were detected after sampling of three fecal specimens. In the fourth case additional specimens were requested on the basis of data derived from the questionnaire. The most frequently cited clinical manifestations were abdominal pain, weight loss, diarrhea and rashes.     

m-OCTOPAMINE, p-OCTOPAMINE AND PHENYLETHANOLAMINE IN RAT BRAIN: A SENSITIVE, SPECIFIC ASSAY AND THE EFFECTS OF SOME DRUGS

Abstract— An enzyme radiochemical assay for p -octopamine, m -octopamine (norphenylephrine) and phenylethanolamine based on the N -methylation of these amines by the enzyme phenylethanolamine N -methyl transferase ( S -adenosyl- l -methionine: phenylethanolamine N -methyl transferase (EC 2.1.1.28) has been developed. [³H]Methyl- S -adenosyl- l -methionine was used as methyl donor. The reaction products are converted to their dansyl derivatives and separated by TLC in three different solvent systems prior to liquid scintillation counting. The method exhibits a sensitivity of less than 10 pg for each amine and is suitable for the measurement of endogenous p -octopamine levels in mammalian brain. The highest levels of p -octopamine were found in the hypothalamus (3.4 ng/g) but despite the sensitivity of the assay, neither phenylethanolamine nor m -octopamine could be detected. After MAO inhibition, however, both of these amines were found to be present. p -Octopamine was increased substantially in all brain regions following the administration of an MAO inhibitor, whereas pretreatment with reserpine produced a significant decrease in the hypothalamus.
