Wikipedia, a multilingual online encyclopedia, is a common starting point for patient medical searches. As its articles can be authored and edited by anyone worldwide, the credibility of the medical content of Wikipedia has been openly questioned. Wikipedia medical articles have also been criticized as too advanced for the general public. This study assesses the comprehensiveness, reliability, and readability of nephrology articles on Wikipedia. The International Statistical Classification of Diseases and Related problems, 10th Edition (ICD-10) diagnostic codes for nephrology (N00-N29.8) were used as a topic list to investigate the English Wikipedia database. Comprehensiveness was assessed by the proportion of ICD-10 codes that had corresponding articles. Reliability was measured by both the number of references per article and proportion of references from substantiated sources. Finally, readability was assessed using three validated indices (Flesch-Kincaid grade level, Automated readability index, and Flesch reading ease). Nephrology articles on Wikipedia were relatively comprehensive, with 70.5% of ICD-10 codes being represented. The articles were fairly reliable, with 7.1 ± 9.8 (mean ± SD) references per article, of which 59.7 ± 35.0% were substantiated references. Finally, all three readability indices determined that nephrology articles are written at a college level. Wikipedia is a comprehensive and fairly reliable medical resource for nephrology patients that is written at a college reading level. Accessibility of this information for the general public may be improved by hosting it at alternative Wikipedias targeted at a lower reading level, such as the Simple English Wikipedia.

Neuropsychiatric sequelae are common following TBI. Several of these syndromes are amenable to treatment. Further investigations are required, however, to better understand the mechanistic aetiology of these conditions and the effectiveness of various therapeutic modalities.

Comparison of the major intraoperative and postoperative complications between unilateral and sequential bilateral total knee arthroplasty in a high-volume community hospital Background: Total knee arthroplasty (TKA) is a common surgical treatment for arthritis. In the event of bilateral knee symptoms, a patient may elect for bilateral TKA (BTKA) under 1 anesthetic or 2 separate unilateral TKAs (UTKA). Controversy exists in the literature regarding the safety of BTKA versus UTKA. We compared the rate of major intraoperative and postoperative complications for BTKA versus UTKA at a high-volume community hospital. Methods:We compared 373 patients who underwent BTKA with 966 who underwent UTKA between May 2008 and May 2011. Health records were used to determine patient characteristics and major intraoperative and postoperative complications. The BTKA and UTKA cohorts were matched for demographic characteristics and comorbidities with the exception of previous transient ischemic attack and previous knee surgery (UTKA > BTKA). Results:Rates of intraoperative and postoperative complications, including cardiovascular, thromboembolic and neurologic complications; deep wound infections; and mortality, did not differ significantly between groups. Bilateral TKA was associated with a greater proportion of patients requiring blood transfusion than UTKA (29.8% v. 8.9%, p < 0.001). Among those transfused, there was no significant difference between the groups in the mean number of units required (1.72 ± 0.77 v. 1.53 ± 0.85 units, p = 0.68). Conclusion:Bilateral TKA was not associated with statistically greater rates of intraoperative and postoperative complications than UTKA, barring the proportion of patients requiring transfusion. Our results support the use of BTKA to treat bilateral knee arthritis in a high-volume community hospital setting.Contexte : La prothèse (ou arthroplastie) totale du genou (PTG) est un traitement chirurgical courant contre l'arthrite. Quand les 2 genoux sont atteints, le patient peut choisir entre une PTG bilatérale (PTGB), qui ne nécessitera qu'une seule anesthésie, ou 2 interventions unilatérales distinctes (PTGU). Dans la littérature, on ne semble pas s'entendre sur l'innocuité de la PTGB contre la PTGU. Nous avons comparé les taux de complications peropératoires et postopératoires majeures associées aux PTGB et aux PTGU dans un hôpital communautaire où s'effectue un volume élevé de telles interventions. Résultats : Les taux de complications peropératoires et postopératoires, y compris cardiovasculaires, thromboemboliques et neurologiques, les infections de plaies profondes et la mortalité n'ont pas varié significativement entre les groupes. Une proportion plus grande de patients soumis à la PTGB a nécessité une transfusion sanguine comparativement aux patients soumis à la PTGU (29,8 % c. 8,9 %, p < 0,001). Parmi les receveurs de transfusions, on n'a noté aucune différence significative entre les groupes quant au nombre moyen d'unités requises (1,72 ± 0,77 c. 1,53 ± 0,85 unité, p = 0,68). Méthodes
