Using bar-code technology to capture clinical intervention data in a hospital with a stand-alone pharmacy computer system

The use of barcode technology to capture data on pharmacists' clinical interventions is described.

COMPARISON OF THE GROWTH INHIBITORY AND BACTERIOCIDAL EFFECTS OF TAUROLIDINE AND TAURULTAM ON A CLINICAL ISOLATE OF ESCHERICHIA-COLI

To investigate the mode of action of Taurolin, an antimicrobial preparation, the growth inhibitory and bacteriocidal effects of taurolidine and taurultam solutions on Escherichia coli isolated from a diagnosed urinary tract infection were examined at 37-degrees-C. The inhibitory effects of taurolidine solutions were observed to be greater than those of taurultam solutions at comparative concentrations; however, the presence of sublethal concentrations of formaldehyde (methylene glycol) associated with taurolidine was sufficient to account for this. The bacteriocidal activity of taurolidine (2.0% w/v) was greater than that of taurultam (4.5% w/v). Both compounds produced biphasic death rates with dissimilar initial slopes, suggested to be due to the presence of formaldehyde in taurolidine solutions. These observations indicate that the growth inhibitory and bacteriocidal effects of Taurolin solutions are primarily due to taurultam, however, the presence of sublethal concentrations of formaldehyde is significant in the expression of this activity.

Immunological detection of Bacteroides fragilis in clinical-samples

A monospecific polyclonal antiserum, prepared against Bacteroides fragilis common polysaccharide antigen purified by polyacrylamide gel immunoblot detected B. fragilis, B. thetaiotaomicron, B. ovatus and Prevotella melaninogenica in pus samples from various anatomical sites by immunofluorescence microscopy of the pus. With standard clinical laboratory culture methods, 36% of 147 samples were positive for one or more of the above bacteria. Of these, B. fragilis accounted for 33%. By immunofluorescent labelling of pus with the common antigen antiserum the detection of these bacteria in the samples increased to 50%. All nine of the blood cultures in which B. fragilis was detected by culture contained bacteria positive for the common antigen. Immunofluorescent labelling of pus samples with a selection of monoclonal antibodies specific for surface polysaccharides which are known to be antigenically variable in culture in vitro and in an animal model of infection showed that these polysaccharides are also variable in natural infection. The results indicate that the common polysaccharide antigen, in contrast to the variable surface polysaccharides, is a suitable target for the immunodetection of B, fragilis in clinical samples from a range of anatomical sites.

Familial ossification of the stylohyoid ligament in a three generation family--a new clinical entity displaying autosomal dominant inheritance

Ossification of the stylohyoid ligament is very common in the Caucasian population. More than 9000 descriptions of apparently isolated case reports on PubMed have been cited over the last 20 years, often associated with an incidental finding on imaging after neck trauma. No cases of familial ossification have been described. We document a family with several affected members, each with an ossified stylohyoid ligament, confirming that ossification may be hereditary in some families and is most likely due to an autosomal dominant gene.
