Pre-surgical radiographic and clinical features as predictors for temporomandibular joint discectomy prognosis

Objectives This study aimed to identify potential clinical and radiological predictors associated with the outcome of discectomies. Methods In this retrospective observational study, the material comprised preoperative CBCT images and medical records of 62 patients with disc derangement disorders, who had undergone discectomy because of disc displacement with reduction (DDwR), disc displacement without reduction (DDwoR), systemic arthritis (SA), or joint hypermobility. Clinical and radiographic variables were analysed in relation to success rate determined by subjective, objective and combined outcomes. Results The success odds ratio was 11 times higher in patients with painful DDwR versus that of SA (p = 0.03), and even 25.9 times higher when considering solely objective outcome (p = 0.03). In the absence of subchondral pseudocyst, there were 5.2 times higher odds to have a successful subjective outcome (p = 0.04). Extensive bone apposition on the temporal joint component indicated a 9.3 times higher likelihood of a failed objective outcome (p = 0.04). Conclusions There is a significant higher risk for combined outcome failure for the diagnosis SA involving the TMJ compared with DDwR. Predictors of importance based on CBCT findings related to the objective outcome failure were extensive bone apposition on the temporal joint component and condylar subchondral pseudocysts for the subjective outcome failure.publishedVersio

Self-reportance of temporomandibular disorders in adult patients attending general dental practice in Sweden from 2011 to 2013

Objectives: The study aim was to evaluate the prevalence of self-reported temporomandibular disorders (TMD) and acceptance or nonacceptance of such disorders in adult patients attending all public dental health services in the County of Sormland, Sweden, during a 3-year period, 2011-2013. Methods: Two questions were asked about TMD and the voluntary mouth-opening capacity was measured. The results were registered in a score 0-3. The registration was completed with a question about each patient's acceptance or nonacceptance of their condition. Results: More than 73,000 registrations of the TMD condition were performed in general dental clinics from 2011 to 2013. The mean prevalence of a TMD score of 1-3 was 5% and was consistent over these years. Seventy percent of these patients were women. The peak prevalence of TMD was registered in patients aged 30-45years (38%), and the frequency declined in older age groups. Reduced voluntary mouth-opening capacity (<= 35 mm) was found in less than 2% of the participants. About one-fifth of the patients with a TMD-score of 1-3 did not accept their condition and wanted professional care. The frequency of nonacceptance of the condition increased with the severity of symptom score: 15%, 27%, and 49% for scores 1, 2, and 3, respectively. Conclusions: This study shows that the prevalence of self-reported TMD in adult patients was consistent from 2011 to 2013 and should be considered as a public health issue in Sweden. Patients with more severe TMD pain symptoms wanted care more frequent. The annual clinical calibrations should be continued to achieve an acceptable level of registration

Comparisons between Full-time and Part-time Pediatric Emergency Physicians in Pediatric Emergency Department

Pediatric emergency medicine is a young field that has established itself in recent decades. Many unanswered questions remain regarding how to deliver better pediatric emergency care. The implementation of full-time pediatric emergency physicians is a quality improvement strategy for child care in Taiwan. The aim of this study is to evaluate the quality of care under different physician coverage models in the pediatric emergency department (ED). Methods: The medical records of 132,398 patients visiting the pediatric ED of a tertiary care university hospital during January 2004 to December 2006 were retrospectively reviewed. Full-time pediatric emergency physicians are the group specializing in the pediatric emergency medicine, and they only work in the pediatric ED. Part-time pediatricians specializing in other subspecialties also can work an extra shift in the pediatric ED, with the majority working in their inpatient and outpatient services. We compared quality performance indicators, including: mortality rate, the 72-hour return visit rate, length of stay, admission rate, and the rate of being kept for observation between full-time and part-time pediatric emergency physicians. Results: An average of 3678 ± 125 [mean ± standard error (SE)] visits per month (with a range of 2487–6646) were observed. The trends in quality of care, observed monthly, indicated that the 72-hour return rate was 2–6% and length of stay in the ED decreased from 11.5 hours to 3.2 hours over the study period. The annual mortality rate within 48 hours of admission to the ED increased from 0.04% to 0.05% and then decreased to 0.02%, and the overall mortality rate dropped from 0.13% to 0.07%. Multivariate analyses indicated that there was no change in the 72-hour return visit rate for full-time pediatric emergency physicians; they were more likely to admit and keep patients for observation [odds ratio = 1.43 and odds ratio = 1.71, respectively], and these results were similar to those of senior physicians. Conclusion: Full-time pediatric emergency physicians in the pediatric ED decreased the mortality rate and length of stay in the ED, but had no change in the 72-hour return visit rate. This pilot study shows that the quality of care in pediatric ED after the implementation of full-time pediatric emergency physicians needs further evaluation
