The aim of this study was to investigate the influence of tumor necrosis factor-alpha (TNF-alpha) in temporomandibular joint (TMJ) synovial fluid and blood on the treatment effect on TMJ pain by intra-articular injection of glucocorticoid in patients with chronic inflammatory TMJ disorders. High pretreatment level of TNF-alpha in the synovial fluid was associated with a decrease of TNF-alpha and elimination of pain upon maximal mouth opening. Elimination of this TMJ pain was accordingly associated with decrease in synovial fluid level of TNF-alpha. There was also a significant decrease of C-reactive protein and TMJ resting pain after treatment. In conclusion, this study indicates that presence of TNF-alpha in the synovial fluid predicts a treatment effect of intra-articular injection of glucocorticoid on TMJ movement pain in patients with chronic TMJ inflammatory disorders.  相似文献

Objective

To explore the molecular function of Osteopontin (OPN) in the pathogenesis of human OA, we compared the expression levels of OPN in synovial fluid with clinical parameters such as arthroscopic observation of cartilage damage and joint pain after joint injury.

Methods

Synovial fluid was obtained from patients who underwent anterior cruciate ligament (ACL) reconstruction surgery from 2009 through 2011 in our university hospital. The amounts of intact OPN (OPN Full) and it’s N-terminal fragment (OPN N-half) in synovial fluid from each patient were quantified by ELISA and compared with clinical parameters such as severity of articular cartilage damage (TMDU cartilage score) and severity of joint pain (Visual Analogue Scale and Lysholm score).

Results

Within a month after ACL rupture, both OPN Full and N-half levels in patient synovial fluid were positively correlated with the severity of joint pain. In contrast, patients with ACL injuries greater than one month ago felt less pain if they had higher amounts of OPN N-half in synovial fluid. OPN Full levels were positively correlated with articular cartilage damage in lateral tibial plateau.

Conclusion

Our data suggest that OPN Full and N-half have distinct functions in articular cartilage homeostasis and in human joint pain.  相似文献

The prevalence of five representative signs and symptoms of temporomandibular pain and dysfunction were evaluated with respect to the age of several different populations. For each of the five signs and symptoms (mouth opening, joint noises, presence of degenerative joint disease, subjectively reported symptoms, and pain on function) no increase was found in the older age group over the middle-age group. In one category (joint sounds), the prevalence decreased in the older age group when compared to the middle-age group. When asked by questionnaire if there was pain on function, the oldest age groups had the lowest proportion of positive responses. As a result of this information it is suggested that the prevalence of temporomandibular disorders diminishes in the elderly population, although not as much as the very few numbers of elderly actually seeking treatment for this disease would suggest.  相似文献

Determination of the opening pressure (OP) during diagnostic lumbar puncture (LP) yields additional information that may impact on treatment and prognosis in disorders affecting the central nervous system (e.g. meningitis). Established methods contain systematic errors as well as risks to the patient. We therefore present a new procedure that allows measurement of the OP by timing the flow of cerebrospinal fluid through a capillary attached to an LP needle. A resistance located between needle and capillary slows down the flow of cerebrospinal fluid so that it becomes independent of the capillary forces acting on it. The time required for the fluid to travel between two marks on the capillary (defining a given volume) can be used to calculate the flow. Since the combined resistance of needle and resistance can be calibrated, the pressure driving the flow--in this case the opening pressure--can be calculated. A simple model was used to evaluate the impact of different resistances and different needles on OP determination. The effects of cellular elements and proteins in the CSF are discussed.  相似文献

The aim of this study was to investigate if the 5-HT3 antagonist granisetron reduces temporomandibular joint (TMJ) pain in patients with systemic inflammatory joint disorders. Sixteen patients with systemic inflammatory joint disease with pain localized over the TMJ region and tenderness to digital palpation of the TMJ were included. The current resting pain (VASRest) and the pain during maximum mouth opening (VAS(MVM)) of the TMJs were assessed with a 100 mm visual analogue scale. An electronic pressure algometer was used to estimate the pressure pain threshold (PPT) over the lateral aspect of the TMJ. Venous blood was collected for measurement of the plasma and serum levels of 5-HT, erythrocyte sedimentation rate, rheumatoid factor and C-reactive protein. The selective 5-HT3 receptor antagonist granisetron or saline were injected into the posterior part of the upper TMJ compartment in a randomized double-blind manner. The patients in the granisetron group had lower VASRest than the patients in the saline group after 10 min. In the granisetron group, VASRest was decreased after 10 min, while VAS(MVM) was decreased and PPT increased after 20 min. In the saline group, VAS(MVM) was decreased after 20 min. In conclusion, granisetron has an immediate, short-lasting and specific pain reducing effect in TMJ inflammatory arthritis. The 5-HT3 receptor may therefore be involved in the mediation of TMJ pain in systemic inflammatory joint disorders.  相似文献

The temporomandibular joint (TMJ) articulates the mandible with the maxilla. Temporomandibular joint disorders (TMD) are dysfunctions of this joint, which range from acute to chronic inflammation, trauma and dislocations, developmental anomalies and neoplasia. TMD manifest as signs and symptoms that involve the surrounding muscles, ligaments, bones, synovial capsule, connective tissue, teeth and innervations proximal and distal to this joint. TMD induce proximal and distal, chronic and acute, dull or intense pain and discomfort, muscle spasm, clicking/popping sounds upon opening and closing of the mouth, and chewing or speaking difficulties. The trigeminal cranial nerve V, and its branches provide the primary sensory innervation to the TMJ. Our clinical work suggests that the auriculotemporal (AT) nerve, a branch of the mandibular nerve, the largest of the three divisions of the trigeminal nerve, plays a critical role in TMD sequelae. The AT nerve provides the somatosensory fibers that supply the joint, the middle ear, and the temporal region. By projecting fibers toward the otic ganglion, the AT nerve establishes an important bridge to the sympathetic system. As it courses posteriorly to the condylar head of the TMJ, compression, injury or irritation of the AT nerve can lead to significant neurologic and neuro-muscular disorders, including Tourette's syndrome,Torticolli, gait or balance disorders and Parkinson's disease. Here, we propose that a proteomic signature of TMD can be obtained by assessing certain biomarkers in local (e.g., synovial fluid at the joint) and distal body fluids (e.g., saliva, cerebrospinal fluid), which can aid TMD diagnosis and prognosis.  相似文献

We have previously shown that intrasplenic fluid extravasation is important in controlling blood volume. We proposed that, because the splenic vein flows in the portal vein, portal hypertension would increase splenic venous pressure and thus increase intrasplenic microvascular pressure and fluid extravasation. Given that the rat spleen has no capacity to store/release blood, intrasplenic fluid extravasation can be estimated by measuring the difference between splenic arterial inflow and venous outflow. In anesthetized rats, partial ligation of the portal vein rostral to the junction with the splenic vein caused portal venous pressure to rise from 4.5 +/- 0.5 to 12.0 +/- 0.9 mmHg (n = 6); there was no change in portal venous pressure downstream of the ligation, although blood flow in the liver fell. Splenic arterial flow did not change, but the arteriovenous flow differential increased from 0.8 +/- 0.3 to 1.2 +/- 0.1 ml/min (n = 6), and splenic venous hematocrit rose. Mean arterial pressure fell (101 +/- 5.5 to 95 +/- 4 mmHg). Splenic afferent nerve activity increased (5.6 +/- 0.9 to 16.2 +/- 0.7 spikes/s, n = 5). Contrary to our hypothesis, partial ligation of the portal vein caudal to the junction with the splenic vein (same increase in portal venous pressure but no increase in splenic venous pressure) also caused the splenic arteriovenous flow differential to increase (0.6 +/- 0.1 to 1.0 +/- 0.2 ml/min; n = 8). The increase in intrasplenic fluid efflux and the fall in mean arterial pressure after rostral portal vein ligation were abolished by splenic denervation. We propose there to be an intestinal/hepatic/splenic reflex pathway, through which is mediated the changes in intrasplenic extravasation and systemic blood pressure observed during portal hypertension.  相似文献

Multiple sclerosis (MS) is an inflammatory disease of unknown etiology involving the central nervous system. Certain clinical manifestations affect the oro-facial region. Three in particular should be of interest to the dentist: trigeminal neuralgia, sensory neuropathy of the trigeminal nerve and facial palsy. The aim of this study was to determine the oral health status, the frequency of subjective symptoms and temporomandibular disorders (TMD) subtype according to Research diagnostic criteria for temporomandibular disorders (RDC/TMD) among MS patients. Examinees in this study were 50 patients suffering from MS, who were at least once treated during their disease in the Clinic Hospital Center, Rijeka, Clinic for Neurology. All examinees had to meet the diagnostic criteria for clinically and laboratory confirmed MS, according to Poser. The results show the difference in mean DMFT (decayed, missing, filled teeth) between MS and the control group. The number of decayed and missing teeth was higher, but the number of filled teeth was significantly lower in MS group. Eighty-two per cent of the subjects with MS had a least one symptom of dysfunction compared with 24% of the subjects in the healthy control group. In the present study, pain, the pain during mouth opening, the difficulty with mouth opening and temporomandibular joint (TMJ) sounds were more commonly reported in the MS group than in the control group. This study shows a statistically significant excess of dental caries and temporomandibular disorders among MS patients compared with the control group. These results suggest that MS is a possible etiological factor in temporomandibular disorders.  相似文献

This paper presents the author's experience with interpositional arthroplasty using an acrylic cylinder in 70 cases of bony ankylosis of the temporomandibular joint. Ankylosis followed trauma in all but one patient. The diagnosis was established when restriction of mouth opening was associated with roentgenologic evidence of deformation of the condyle, obliteration of the joint space, and abnormal bone formation in and around the joint. The pathologic changes were classified into four types depending on severity, and each type influenced the treatment. Surgical treatment included creation of a transversely elliptical gap between the two bony components of the joint using a neurosurgical burr and perforator and a chisel through a preauricular approach and interposition of an acrylic cylinder. This maintained the gap, facilitated movement, and encouraged nonunion. The results following a long follow-up of 2 to 10 years showed uniformly good results with a range of mouth opening varying from 2 to 5 cm. Only three bilateral cases recurred and two others had a limited range of mouth opening, with interincisor distance varying from 2 to 2.5 cm.  相似文献

BackgroundWhile excision of the trochanteric bursae to treat lateral hip pain has increased in popularity, no comparison exists between the surgical outcomes and complications of the open and arthroscopic techniques involving trochanteric bursectomy. The purpose of this study was to determine the efficacies and complication rates of arthroscopic and open techniques for procedures involving trochanteric bursectomy.MethodsThe terms “trochanteric,” “bursectomy,” “arthroscopic,” “open,” “outcomes,” and “hip” were searched in five electronic databases. Fifteen studies from 120 initial results were included. Patient-reported outcomes (PRO), pain, satisfaction, and complications were included for analysis.ResultsFive hundred-two hips in 474 total patients (77.7% female) were included in this study. The average age was 54. The fourteen distinct PRO scores that were reported by the included studies improved significantly from baseline to final mean follow-up (12-70.8 months for open; 12-42 months for arthroscopic) for both approaches, demonstrating statistically significant patient benefit in a variety of hip arthroscopy settings (P > 0.05). The complication rates of all procedures ranged from 0%-33% and failure to improve pain ranged from 0%-8%. Patient satisfaction with surgery was high at 95% and 82% reported a willingness to undergo the same surgery again. No significant mean differences were found between the open and arthroscopic techniques.ConclusionThe open and arthroscopic approaches for trochanteric bursectomy are both safe and effective procedures in treating refractory lateral hip pain. No significant differences in PROs, pain, total complications, severity of complications, and total failures were seen between technique outcomes.Level of Evidence: IV  相似文献

A novel method for the measurement of knee joint forces in-vivo is described. A thin (0.2mm) flexible electronic pressure sensor was inserted through a narrow arthroscopic portal into the osteoarthritic medial compartment of the knee joint. The sensor partially covered the load bearing area. The surgery was performed under local anaesthetic during normal arthroscopic examination following patient consent. Results are presented for 11 patients. The method was used in a pilot study to assess the effects of four valgus knee braces on medial compartment forces. An analysis of variance could not detect un-loading by any brace although there were large variations in force output. These variations may be attributable to shifts in the sensor position. In-vivo measurement of joint force is technically feasible.  相似文献

Nearly all aquatic-feeding vertebrates use some amount of suction to capture prey items. Suction prey capture occurs by accelerating a volume of water into the mouth and taking a prey item along with it. Yet, until recently, we lacked the necessary techniques and analytical tools to quantify the flow regime generated by feeding fish. We used a new approach; Digital Particle Image Velocimetery (DPIV) to measure several attributes of the flow generated by feeding bluegill sunfish. We found that the temporal pattern of flow was notably compressed during prey capture. Flow velocity increased rapidly to its peak within 20 ms of the onset of the strike, and this peak corresponded to the time that the prey entered the mouth during capture. The rapid acceleration and deceleration of water suggests that timing is critical for the predator in positioning itself relative to the prey so that it can be drawn into the mouth along with the water. We also found that the volume of water affected by suction was spatially limited. Only rarely did we measure significant flow beyond 1.75 cm of the mouth aperture (in 20 cm fish), further emphasizing the importance of mechanisms, like locomotion, that place the fish mouth in close proximity to the prey. We found that the highest flows towards the mouth along the fish midline were generated not immediately in front of the open mouth, but approximately 0.5 cm anterior to the mouth opening. Away from the midline the peak in flow was closer to the mouth. We propose that this pattern indicates the presence of a bow wave created by the locomotor efforts of the fish. In this scheme, the bow wave acts antagonistically to the flow of water generated by suction, the net effect being to push the region of peak flow away from the open mouth. The peak was located farther from the mouth opening in strikes accompanied by faster locomotion, suggesting faster fish created larger bow waves.  相似文献
