Safety and utilization of peripherally inserted central catheters versus midline catheters at a large academic medical center.

Background: Peripherally inserted central catheters (PICCs) are a commonly used central intravenous (IV) access device, which can be associated with significant complications. Midline catheters (MCs) are peripheral IV access devices that may reduce the need for central lines and hence decrease central line-associated bloodstream infections. The objective of this study is to compare the utilization and safety of PICCs and MCs.

The FAS/cd95 promoter single-nucleotide polymorphism -670 A/G and lupus erythematosus.

An increased level of circulating nuclear antigens caused by apoptosis is thought to be responsible for the production of autoantibodies in lupus erythematosus (LE). The presentation of these antigens to immunologically competent cells may trigger systemic autoimmunity. The influence of a functional single-nucleotide polymorphism at position -670 in the promoter of the apoptosis gene FAS on susceptibility to autoimmune diseases including systemic LE has been a controversial subject.

Neurodevelopmental functioning in children with FAS, pFAS, and ARND.

Objective: The purpose of this article is to compare the neurodevelopmental profiles of 78 foster and adopted children with fetal alcohol syndrome (FAS), partial FAS (pFAS), or alcohol-related neurodevelopmental disorder (ARND).

Method: Seventy-eight foster and adopted children underwent a comprehensive diagnostic evaluation. By using criteria more stringent than those required by current guidelines, the children were placed in 1 of 3 diagnostic categories: FAS, pFAS, or ARND.

T and B cells target identical regions of the non-collagenous domain 1 of type VII collagen in epidermolysis bullosa acquisita.

Epidermolysis bullosa acquisita (EBA) is a severe immunobullous disease and is caused by IgG against type VII collagen (Col VII) of anchoring fibrils. In this study, utilizing ELISA and immunoblot, 13/15 EBA sera but 0/20 bullous pemphigoid sera and 0/30 healthy control sera showed IgG reactivity with distinct recombinant subregions of the non-collagenous domain 1 (NC1) of Col VII. In two EBA patients, IgG titers against Col VII-NC1 were grossly correlated to clinical disease activity.

Confocal laser-scanning capillaroscopy: a novel approach to the analysis of skin capillaries in vivo.

Background: New techniques for diagnostics and therapy in dermatology are becoming increasingly non-invasive, among which confocal laser-scanning microscopy (CLSM) is the most prevalent. It allows visualization of cellular structures of the skin up to a depth of 300 microm in vivo. Until now, most studies have been conducted on pathologically altered skin, mostly oncologic lesions.
