Real-time PCR-assay in the delivery suite for determination of group B streptococcal colonization in a setting with risk-based antibiotic prophylaxis.

Objective: Intrapartum antibiotic prophylaxis (IAP) reduces the incidence of neonatal early onset group B streptococcal infections. The present study investigated if an automated PCR-assay, used bedside by the labor ward personnel was manageable and could decrease the use of IAP in a setting with a risk-based IAP strategy.

Methods: The study comprises two phases.

Using a virtual reality system to study balance and walking in a virtual outdoor environment: a pilot study.

Falls and fall-related injuries are a major problem for elderly persons. Most falls occur during walking and turning, and the risk of falling increases when attention is diverted to something besides walking. It is often difficult to standardize methods for testing balance and fall tendency in a clinically relevant setting.

Expression of stratum corneum chymotryptic enzyme in human sebaceous follicles.

Stratum corneum chymotryptic enzyme (SCCE) may be involved in desquamation, a process necessary for maintaining a normal anatomy at all sites where there is continuous turnover of cornified epithelia. Using immunohistochemistry and in situ hybridization, we have, in this work, analysed SCCE expression in the sebaceous follicle. We found expression of SCCE in luminal parts of the pilary canal, common sebaceous ducts and proximal sebaceous ducts.

In situ evidence that the population of Langerhans cells in normal human epidermis may be heterogeneous.

Epidermal Langerhans cells (LC) may occur in subsets with different phenotypic and functional characteristics. In this work give further evidence that the CD1a-positive LC population in the normal human epidermis may be heterogeneous. We found that one of our monoclonal antibodies (TE4B) to stratum corneum chymotryptic enzyme (SCCE) stained a population of dendritic cells in the normal epidermis in addition to high suprabasal keratinocytes.
