RESUMO
AIMS: To investigate the associations between signs of painful temporomandibular disorders (TMD) and number of tender points (TPs) and fibromyalgia in adolescents, as well as the relationship between TPs and pressure-pain threshold (PPT) in individuals presenting with local, regional, or widespread pain as a way to investigate the presence of central sensitization (CS). METHODS: The sample consisted of 690 Brazilian adolescents with and without signs of painful TMD, aged 12 to 14 years old. Painful TMD was classified according to the Research Diagnostic Criteria for TMD (RDC/TMD) Axis I. The criteria established by Yunus were applied to assess juvenile fibromyalgia and TPs. Mann-Whitney and chi-square tests were applied to test the associations between signs of painful TMD and demographic variables. Regression models were used to estimate the association between signs of painful TMD and number of TPs and to determine which additional predictive variables were associated with TPs. Regression analyses were performed to test the associations between PPT values and number of TPs. Fisher test was used to estimate the association between signs of painful TMD and FM. RESULTS: Significant associations between signs of painful TMD and the number of TPs (P < .001), as well as between TPs and the PPT values for local, regional, and widespread pain (P < .001), were found. No association between signs of painful TMD and fibromyalgia was found (P = .158). CONCLUSION: Individuals with signs of painful TMD presented with more TPs compared to pain-free adolescents. Moreover, the higher the number of TPs, the lower the PPT. This finding suggests that adolescents with signs of painful TMD are at increased risk of presenting with CS.

Temporomandibular disorders (TMD) are a highly prevalent, painful musculoskeletal condition affecting the masticatory system, and are frequently associated with migraines (M) and other diseases. This study aimed to investigate the association between painful TMD and M with other painful conditions and systemic diseases, such as cervicalgia, body pain (BP), ear-nose-throat disorders, musculoskeletal disorders, diabetes, cardiopulmonary diseases and gastritis/peptic ulcer. METHODS: This was a cross-sectional study conducted in a sample of 352 individuals. Participants were stratified into three groups according to the presence of painful TMD and M: controls [individuals free of TMD and any headache (HA)]; TMD only (presence of painful TMD, but free of any HA); and TMD+M (presence of painful TMD and M). TMD was classified according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) - Axis I. Nonspecific physical symptoms (NSPS) were assessed by RDC/TMD - Axis II. The International Classification of Headache Disorders - II criteria, second edition, were applied to identify and classify primary HA. Other painful conditions and systemic diseases were assessed by volunteers' self-report. The prevalence of all assessed conditions was higher in the TMD+M group. Multiple regression models showed that cervicalgia was associated with the TMD only group (p<0.05), whereas gender (p<0.05), cervicalgia (p<0.05), BP (p<0.05) and NSPS (p<0.05) were significantly associated with the TMD+M group. Our results suggest that individuals with a comorbidity (TMD associated with M) have a more severe condition than those presenting only painful TMD.

Delayed graft function (DGF) is very high in our center (70%-80%), and we usually receive a kidney for transplant after more than 22 hours of static cold ischemia time (CIT). Also, there is an inadequate care of the donors, contributing to a high rate of DGF. We decided to test whether machine perfusion (MP) after a CIT improved the outcome of our transplant patients. We analyzed the incidence of DGF, its duration, and the length of hospital stay (LOS) in patients who received a kidney preserved with MP after a CIT (hybrid perfusion-HP). We included 54 deceased donors kidneys preserved with HP transplanted from Feb/13 to Jul/14, and compared them to 101 kidney transplants preserved by static cold storage (CS) from Nov/08 to May/12. The median pumping time was 11 hours. DGF incidence was 61.1% vs 79.2% (P = .02), median DGF duration was 5 vs 11 days (P < .001), and median LOS was 13 vs 18 days (P < .011), for the HP compared to CS group. The observed reduction of DGF with machine perfusion did not occur in donors over 50 years old. In the multivariate analysis, risk factors for DGF, adjusted for CIT, were donor age (OR, 1.04; P = .005) and the absence of use of MP (OR, 1.54; P = .051). In conclusion, the use of HP contributed to faster recovery of renal function and to a shorter length of hospital stay.
