Objective. To systematically review medical and surgical foot intervention studies in rheumatoid arthritis (RA), focusing on clinical efficacy, study quality, and risk of harm. Methods. We searched appropriate databases using a combination of the terms "rheumatoid arthritis" and "foot" against terms indicating treatment; we also hand-searched references. We selected articles in English (1968 -2003) comprising randomized controlled trials (RCTs), controlled clinical trials (CCTs), prospective observational studies, and large retrospective observational surgical studies (>50 cases). RCT quality was examined using Jadad scoring; other designs were assessed qualitatively. Results. Inclusion criteria were met by 33 of 894 identified studies, comprising 5 RCTs and 1 CCT (all nonsurgical), 15 prospective observational studies (8 nonsurgical, 7 surgical), and 12 large retrospective studies (all surgical). Functional, custom-designed and semirigid orthoses and extra-depth shoes were effective in single RCTs of variable quality; no comparative studies have been conducted. This finding was supported by a CCT and prospective observational studies. There was no evidence of harm. There were no controlled trials of surgery. Prospective observational studies suggest that forefoot arthroplasty and first metatarsophalangeal joint implants, but not plantar callous debridement, are effective. Comparative retrospective analyses suggest that some procedure variants may be better, and surgery may relieve pain better than orthoses. Infection was the main risk. Conclusion. RCT evidence shows that orthoses and special shoes are likely to be beneficial in patients with RA. The only evidence of benefit from surgery comes from observational studies, because no RCTs have been conducted. Further RCT evidence is needed, although well-designed observational studies may be helpful.

Canadian Inuit infants suffer the highest rate of lower respiratory tract infections (LRTI's) in the world. The causes of this are incompletely understood. The primary objective of this study was to determine whether there exists an association between respiratory morbidity and oral aspiration in Inuit children. A retrospective chart review was conducted including children from Nunavut who underwent Video Fluoroscopic Swallowing Study between the years of 2001 to 2015. The primary outcome was hospitalization for LRTI. We hypothesized that infants found to have aspiration would experience a higher rate of admissions for LRTI than those with normal swallowing studies. One‐hundred and twenty‐seven patients were identified, of whom 94 were included. Fifty‐six percent of patients had an abnormal swallowing study. Compared with patients with normal swallowing, the incidence rate of LRTI was higher in patients with aspiration (incidence rate ratio [IRR] = 1.51; 95% confidence interval [CI] = 1.23‐1.87) and in patients with penetration (IRR = 1.40; 95% CI = 1.11‐1.76). Fourteen percent of patients had confirmed laryngeal cleft; patients with confirmed presence of this also had a higher incidence rate of LRTI (IRR = 1.66; 95% CI = 1.32‐2.07). The incidence of abnormal swallowing study showed an 11‐fold variation across the five regions in Nunavut, with the highest prevalence in west Qikiqtani Region (Baffin Island). We conclude that swallowing dysfunction is not only prevalent amongst Canadian Inuit but clinically significant. This is the first study to demonstrate an association between swallowing dysfunction and respiratory morbidity in this population. Geographic distribution patterns and high rates of laryngeal cleft may point to a potential genetic etiology for what remains at this point, idiopathic swallowing dysfunction.
A 17-year-old girl was found unconscious in a running vehicle. She developed very severe acute respiratory distress syndrome (which was treated with rescue high-frequency oscillation), hemodynamic instability, acute kidney injury, rhabdomyolysis, and remained comatose with a Glasgow Coma Scale score of 3 and gasping respirations for 67 hours (when the Glasgow Coma Scale score improved to 6, with tachypnea to Paco 2 28 and pH 7.5). By 92 hours, she was obeying commands, and she was extubated at 96 hours, shortly after which she was conversing with family and texting on her phone. A magnetic resonance imaging (MRI) scan 6 days after being found showed subacute infarctions affecting the medial aspect of the globus pallidus bilaterally as well as a small cortical/subcortical infarction in the right parietal lobe. At a 7-week follow-up, she had no delayed-onset signs of brain injury. This case demonstrated that neurologic prognostication after carbon monoxide poisoning may be unreliable for more than 72 hours after injury. We discuss that it is possible that the mitochondrial dysfunction induced by carbon monoxide was responsible for a functional coma without irreversible brain injury, similar to the mechanism of cytopathic hypoxia in multiple-organ dysfunction that allows some other organ recovery without necrosis in survivors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
