A prospective study of 300 consecutive deliveries has been made to assgss the benefits and acceptability of ambulation during spontaneous labour. Ambulation during the first stage occurred in 48 patients with 55 non-ambulant patients acting as controls. No difference in the length of first or second stage, incidence of fetal distress or mode of delivery was observed. In spite of the lack of apparent advantage to the fetal condition, ambulation was acceptable to both patients and nursing staff and should not be discouraged.
We compared Guillain-Barré syndrome (GBS) cases reported from cities in the United States in 1976-1977 with spouse or associate controls to detect possible HLA associations. HLA-A11 was somewhat less common among 92 cases than among 100 controls (p = 0.04). The 38 patients and 42 controls vaccinated against A/NJ/76 differed slightly in overall distribution of B locus antigens (p = 0.06), but the individual HLA-B antigen associations were more easily explained by chance. The 54 unvaccinated cases showed no apparent relation to HLA type. These findings should encourage further immunogenetic study of etiologically related GBS cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
