I n dermatology practice, patients frequently present witharecalcitranteruptiondistinguishedby thepresence of edematous, urticarial, intensely pruritic papules.After analysisofpatientbiopsyspecimens, thedermatopathologist will often report a “dermal hypersensitivity reaction” (DHR) characterized by an eosinophil-rich infiltrate. The only clinical differentials that correspond to this pathologic...

Oxidative stress is a major contributing factor in a variety of neurodegenerative and vascular diseases. In vitro assessment of a major oxidant reactive nitrogen oxide species (RNOS) using dihydrorhodamine 123 (DHR 123) is a useful assay to quantify the reactive oxygen species in a cell. DHR 123, non-fluorescent laser dye freely penetrates the cell membrane and stains the mitochondria. Density ...

BACKGROUND Education and patient care are essential to academic hospitalists, and residents are key partners in these goals. The Accreditation Council for Graduate Medical Education (ACGME) duty-hour restrictions (DHR) likely impacted aspects of resident teaching, well-being, and patient care practices that affect the duties of academic hospitalists. OBJECTIVE To determine the impact of DHR o...

INTRODUCTION The possible hypothesis of a link between periodontitis and rheumatoid arthritis (RA), specifically anti-citrullinated protein antibody (ACPA) positive RA, prompted us to investigate the prevalence of periodontitis in the Swedish Epidemiological Investigation of RA (EIRA), a well-characterised population-based RA case-control cohort. METHODS Periodontal status of 2,740 RA cases a...

AIM The Danish Heart Registry (DHR) seeks to monitor nationwide activity and quality of invasive diagnostic and treatment strategies in patients with ischemic heart disease as well as valvular heart disease and to provide data for research. STUDY POPULATION All adult (≥15 years) patients undergoing coronary angiography (CAG), percutaneous coronary intervention (PCI), coronary artery bypass gr...

AIM OF DATABASE The aim of the Danish Hip Arthroplasty Register (DHR) is to continuously monitor and improve the quality of treatment of primary and revision total hip arthroplasty (THA) in Denmark. STUDY POPULATION The DHR is a Danish nationwide arthroplasty register established in January 1995. All Danish orthopedic departments - both public and private - report to the register, and registr...

BACKGROUND AND PURPOSE It has been suggested that the risk of prosthetic joint infection (PJI) in patients with total hip arthroplasty (THA) may be underestimated if based only on arthroplasty registry data. We therefore wanted to estimate the "true" incidence of PJI in THA using several data sources. PATIENTS AND METHODS We searched the Danish Hip Arthroplasty Register (DHR) for primary THAs...

We consider the mean delay optimization in the M/G/1 queue for service time distributions that have a tail with decresing hazard rate (DHR). If the DHR property is valid for the whole distribution, then it is known that the ForegroundBackground (FB) discipline, which gives full priority to the job with least amount of attained service, is optimal among nonanticipating scheduling disciplines. Ho...

Multiple drug hypersensitivity (MDH) is a syndrome that develops as a consequence of massive T-cell stimulations and is characterized by long-lasting drug hypersensitivity reactions (DHR) to different drugs. The initial symptoms are mostly severe exanthems or drug rash with eosinophilia and systemic symptoms (DRESS). Subsequent symptoms due to another drug often appear in the following weeks, o...
