Population screening for coeliac disease in primary care by district nurses using a rapid antibody test: diagnostic accuracy and feasibility study.

Objective: To evaluate the feasibility and diagnostic accuracy of screening for coeliac disease by rapid detection of IgA antibodies to tissue transglutaminase performed in primary care.

Design: District nurses screened 6 year old children using rapid antibody testing of finger prick blood. They also collected capillary blood samples for laboratory determination of IgA and IgG antibodies to endomysium and IgA antibodies to tissue transglutaminase.

Aetiological monitor of congenital abnormalities: a case-control surveillance system.

An Aetiological Monitor of Congenital Abnormalities was launched in Hungary on 1 January 1980 with the purpose to obtain aetiological information parallel with the reporting of congenital abnormalities. A questionnaire is sent to all mothers having babies with well defined major congenital abnormalities within one month after being reported to the Register. Diseases during pregnancy, drugs taken during pregnancy as well as employment and type of work made by the pregnant are studied.

Microelectrode investigations of learning phenomena in snail (Helix pomatia) neurones.

We have examined changes of postsynaptic potentials and of pattern activity of the identified silent and oscillatory snail neurones in Helix pomatia during conditioning. Local changes of EPSP or IPSP have been recorded during association following the first stimulus in the silent cells, whereas spike discharges could be observed in response to the 2nd stimulus. In the oscillatory neurones changes of pattern activity have been recorded following the 2nd stimulus, while the first stimulus proved to be ineffective.
