The Next Wave: Confexting

Radiology conferences enable participants the opportunity to ask experts questions through question and answer (Q and A) sessions or individually. Given the time limitations and intimidating circumstances, we incorporated conference text messaging (confexting) as a method of increasing interactivity between the audience and speakers. During a 5-day radiology conference, text messaging was utilized for anonymous interactivity between the audience and speakers during Q and A sessions. There were 324 text messages; 76 of these were either follow-up statements or questions related to earlier text messages. Forty-two questions were submitted via paper notes. There was a general trend of an increasing number of text messages and a decreasing number of paper notes. The anonymous text messaging system was found to be an effective method for interactivity between the audience and the speakers. The questions and answers could be presented in a PowerPoint format at the formal Q and A sessions. Questions texted to the authors during their talks could be immediately answered or addressed in subsequent talks. Although difficult for some individuals to embrace technology, confexting allows for interactivity and prompts discussion. Confexting is an effective method for interactivity between the audience and speakers not previously utilized in a conference setting. The anonymity and asynchronous communication enable conference participants to submit more questions than in the traditional setting. The speakers may be able to explain more thoroughly difficult concepts more thoroughly with additional slides at Q and A sessions or may immediately answer texted questions during their talks.     

Algorithm for the treatment of type 2 diabetes: a position statement of Brazilian Diabetes Society

The Brazilian Diabetes Society is starting an innovative project of quantitative assessment of medical arguments of and implementing a new way of elaborating SBD Position Statements. The final aim of this particular project is to propose a new Brazilian algorithm for the treatment of type 2 diabetes, based on the opinions of endocrinologists surveyed from a poll conducted on the Brazilian Diabetes Society website regarding the latest algorithm proposed by American Diabetes Association /European Association for the Study of Diabetes, published in January 2009.An additional source used, as a basis for the new algorithm, was to assess the acceptability of controversial arguments published in international literature, through a panel of renowned Brazilian specialists. Thirty controversial arguments in diabetes have been selected with their respective references, where each argument was assessed and scored according to its acceptability level and personal conviction of each member of the evaluation panel.This methodology was adapted using a similar approach to the one adopted in the recent position statement by the American College of Cardiology on coronary revascularization, of which not only cardiologists took part, but also specialists of other related areas.     

医学催眠术治疗颞下颌紊乱

颞下颌紊乱的患者有咀嚼肌系统或颞下颌关节的功能障碍或二者兼有,典型症状为咀嚼肌疼痛,常伴有耳痛、头痛、面痛并向颈部或肩部放射,发病率约为5％左右。目前普遍认为心理压力是其主要原因,对该病的保守治疗方法主要包括对牙齿的治疗、理疗和抗炎治疗等。本研究目的是探讨医学催眠术对减轻颞下颌紊乱疼痛症状的作用。     

Rheumatoid arthritis: explanatory power of specific radiographic findings for patient clinical status

Radiographs of the hands and wrists of 201 patients with rheumatoid arthritis (RA) were scored for erosion, joint space narrowing, and malalignment. The explanatory power of these findings for measures of clinical status was studied with stepwise multiple linear regression analyses. Radiographic scores explained 59.2% of variation in physical joint count deformity scores, 58.5% of variation in limited motion scores, 22.5% of variation in grip strength scores, 20.5% of variation in button test scores, and 13.5% of variation for the American Rheumatism Association (ARA) Functional Class. Malalignment scores best explained variation in physical deformity, limited motion, and button test scores; joint-space-narrowing scores best explained variation in grip strength; erosion scores best explained variation in ARA Functional Class. When age, duration of disease, erythrocyte sedimentation rate, and rheumatoid factor titer were included in the regression analyses, results were similar to those without these variables. Therefore quantitative scores of specific radiographic findings are in themselves explanatory for measures of clinical status.
