Comparative Study
Perioperative outcomes in patients with rheumatoid versus osteoarthritis for total hip arthroplasty: a population-based study.
Little is known about perioperative outcomes among the subset of patients undergoing total hip arthroplasty (THA) for a diagnosis of rheumatoid arthritis (RA) rather than osteoarthritis (OA). We sought to 1) identify the prevalence of RA in patients undergoing THA, 2) compare their demographics to those being operated on for OA, 3) determine differences in perioperative outcomes and 4) analyse if RA represents an independent risk factor for complications, mortality, utilisation of resources, increased length of stay and cost. ⋯ In THA patients suffering from RA, perioperative risk for complications and utilization of health care resources continues to be increased compared to OA patients.

Comparative Study
Fibromyalgia: gender differences and sleep-disordered breathing.
The prevalence of fibromyalgia (FM) is much lower in men than in women. Therefore, current knowledge about this chronic pain syndrome emerged mainly from research on women. The aim of the present study was to compare clinical symptoms and sleep parameters between male and female FM patients. ⋯ Alterations in sleep respiratory patterns were more highly prevalent in male than in female FM patients. More so in male FM patients, the alterations in sleep patterns, non-refreshing sleep, and other FM-related symptoms observed in this population might be part of a primary sleep-disordered breathing.
