    Full Text Available Osteoarthritis, a degenerative joint disease, is the most commonrheumatic disorder mainly in a geriatric population. Manifestationsare pain, stiffness and functional loss in the affected joint.According to etiology it is classifi ed as primary (or idiopathicand secondary. Some risk factors for disease development aregenetics, race, age, sex, obesity, occupational activities andarticular biomechanics. Pathogenesis is the same for any cause orlocalization, being catabolic alterations, with synthesis, inhibitionand reparing intent of the cartilage matrix. Metalloproteinases andcytokines (IL-1,IL-6,TNF-α actions promote infl ammatory reactionand cartilage degradation. Pain, the most important symptom,does not correlate with radiologic fi ndings. Peripheral osteoarthritisoccurs predominantly in the knee, hip and hand. Diagnosis is basedon clinical features, laboratorial tests and radiological changes.Rheumatological associations’ guidelines for treatment includenon-pharmacologic (education, physiotherapy, assistive devices,and pharmacologic (analgesics, anti-infl ammatory drugs therapyand surgery. Arthroplasty seems to work better than medicines, butshould be used if other treatments have failed.

    Little information is available regarding the long-term effects, if any, of running on the musculoskeletal system. The authors compared the prevalence of degenerative joint disease among 17 male runners with 18 male nonrunners. Running subjects (53% marathoners) ran a mean of 44.8 km (28 miles)/wk for 12 years. Pain and swelling of hips, knees, ankles and feet and other musculoskeletal complaints among runners were comparable with those among nonrunners. Radiologic examinations (for osteophytes, cartilage thickness, and grade of degeneration) also were without notable differences among groups. They did not find an increased prevalence of osteoarthritis among the runners. Our observations suggest that long-duration, high-mileage running need to be associated with premature degenerative joint disease in the lower extremities.

  5. Radiographic evaluation of degenerative joint disease in horses: interpretive principles

    Degenerative joint disease in horses is characterized by the progressive deterioration of articular cartilage of synovial joints. The morbidity associated with degenerative joint disease, particularly the loss of function in pleasure and performance horses, costs horse owners millions of dollars each year. Although new drugs, such as polysulfated glycosaminoglycans and hyaluronic acid, are available for the treatment of patients with degenerative joint disease, the success of therapy depends on early diagnosis. Diagnostic imaging strategies, therefore, should focus on accurate and timely diagnosis of degenerative joint disease to provide prompt therapy. Early identification of degenerative joint disease is also beneficial because the use and/or training methods of affected patients may be altered, possibly limiting the progression of the disease. The pathogenesis of degenerative joint disease is complex and multifactorial. Current evidence suggests that initiating factors lead to a final common pathway-breakdown of articular cartilage. There are many diagnostic tests that aid practitioners in detecting degenerative joint disease; however, the most important imaging technique is radiography. During the early stages of the disease, radiographic changes may be slight; therefore, it is essential that practitioners have adequate equipment to obtain high-quality radiographs. Thinning of the joint space, osteophytosis, enthesopathy, changes in subchondral bone, and increased synovium and synovia provide radiographic evidence of degenerative joint disease. By understanding the pathophysiology of the disease and how technical alterations affect the subtle radiographic changes, practitioners can more accurately diagnose degenerative joint disease during its early stages and institute proper therapy

  6. Degenerative joint disease in weight-lifters. Fact or fiction?

    FitzGerald, B.; McLatchie, G. R.

    1980-01-01

    A clinical and radiological study of upper and lower limb joints was carried out on 25 experienced weight-lifters to identify the extent of degenerative joint disease (Osteoarthrosis) produced by this sport. Although significant degenerative changes were found in five lifters (20%). This figure is not greater than that found in the general population within the age group studied. There were more degenerative changes found in Olympic style weight-lifters (30.7%) than in power lifters (8.3%). T...

  7. Chronic repetitive trauma: A cause of atypical degenerative joint disease

    Six cases of amateur athletes who have severe atypical degenerative joint disease (DJD) are presented; their histories suggest that chronic, repetitive trauma was causative in the development of their arthorpathy. Although many examples of this process have been reported in professional athletes, it has not been reported in amateurs. As participation in athletic activities increases we can, perhaps, expect to see more of this type of DJD in the future. (orig.)

  8. Inflammatory and degenerative disease in the temporomandibular joint

    1996-01-01

    Temporomandibular joint (TMJ) arthroscopy is an established technique withhigh diagnostic accuracy regarding synovitis and degenerative changes of the articularfibrocartilage and disk. However, so far no studies have been done to correlate themacroscopic and histologic findings with each arthroscopic criterion. Thereforepatients with TMJ internal derangement (ID) were investigated by arthroscopy andarthrotomy (with biopsy) and the findings were compared with observations usinglight microscopy...

  9. Pedicle marrow signal intensity changes in the lumbar spine: a manifestation of facet degenerative joint disease

    Objective. Signal intensity changes in lumbar pedicles, similar to those described in vertebral body endplates adjacent to degenerated discs, have been described as an ancillary sign of spondylolysis on MRI. The purpose of this study was to determine whether pedicle marrow signal intensity changes also occur in association with facet degenerative joint disease.Design. Eighty-nine lumbar spine MRI examinations without spondylolysis were reviewed for marrow signal intensity changes in pedicles and vertebral bodies as well as for facet degenerative joint disease.Results. Five percent (46/890) of lumbar pedicles in 23 patients had marrow signal intensity changes. Ninety-one percent (42/46) of the abnormal pedicles had adjacent degenerative joint disease of the facets, while only 21% (189/890) of normal pedicles had adjacent facet degenerative joint disease (p<0.001). Eighty-nine percent (41/46) of the pedicles with marrow signal intensity changes had adjacent degenerative disc disease.Conclusions. Pedicle marrow signal intensity changes are not a specific sign of spondylolysis; they are commonly seen with adjacent facet degenerative joint disease in the absence of spondylolysis. Pedicle marrow signal intensity changes are probably a response to abnormal stresses related to abnormal motion or loading caused by the degenerative changes in the spinal segment. (orig.)

  10. Osteochondrosis, degenerative joint disease, and vertebral osteophytosis in middle-aged bulls.

    Weisbrode, S E; Monke, D R; Dodaro, S T; Hull, B L

    1982-10-01

    Twenty-five middle-age (65 +/- 18 months) dairy bulls sent to slaughter for nonmedical reasons were evaluated for joint disease in the stifle and the lumbar vertebrae. Fourteen bulls had degenerative joint disease and 3 had osteochondrosis (osteochondritis dissecans) of the distal end of the femur. These lesions predominantly involved the lateral trochlear ridge. Twenty-one bulls had vertebral osteophytosis. Degenerative joint disease and vertebral osteophytosis were common in these middle-aged bulls and, even when severe, were rarely associated with lameness. PMID:7141968

  11. Diagnosis and Treatment of Degenerative Joint Disease in a Captive Male Chimpanzee (Pan troglodytes)

    Videan, Elaine N; Lammey, Michael L; Lee, D Rick

    2011-01-01

    Degenerative joint disease (DJD), also known as osteoarthritis, has been well documented in aging populations of captive and free-ranging macaques; however, successful treatments for DJD in nonhuman primates have not been published. Published data on chimpanzees show little to no DJD present in the wild, and there are no published reports of DJD in captive chimpanzees. We report here the first documented case of DJD of both the right and left femorotibial joints in a captive male chimpanzee. ...

  12. Proteoglycan synthesis and osteophyte formation in 'metabolically' and 'mechanically' induced murine degenerative joint disease: an in-vivo autoradiographic study.

    van der Kraan, P. M.; Vitters, E.L.; van Beuningen, H. M.; van den Berg, W. B

    1992-01-01

    We investigated the in-vivo proteoglycan synthesis in specific areas of murine knee joint articular cartilage after the induction of degenerative joint disease by means of 35S-sulphate autoradiography. Degenerative joint disease was induced either by direct interference with cartilage metabolism (papain and iodoacetate), or by the induction of joint instability (collagenase). Injection of iodoacetate and papain led to inhibition of proteoglycan synthesis mainly in the central parts of the pat...

  13. Stress radiographs in the evaluation of degenerative femorotibial joint disease

    Thirty-eight osteoarthrotic knees were examined to assess the widths of the femorotibial joint spaces. Radiographs were exposed with the patient lying, in a standing position, and with an adduction and abduction force. Forced compression of the osteoarthrotic joint compartment caused, on average, 18% greater narrowing than when loading it in the standing position. Compared to the joint space at rest, the non-weight-bearing compartment widened by 16% in the standing position and narrowed by 20% when stress was applied. Furthermore, the results showed an increase in laxity proportional to the degree of arthrosis. Stress radiographs significantly display the real cartilage width of both joint compartments. Knowledge of the condition of the articular cartilage in the non-weight-bearing compartment is important when considering a transfer of loading stresses by means of osteotomy. (orig.)

  14. Triple pelvic osteotomy: effect on limb function and progression of degenerative joint disease

    The objective of this study was to evaluate prospectively the outcome of 21 clinical patients treated with triple pelvic osteotomies during the year following surgery. Specific aims included documenting the time of and extent of improved limb function as measured by force plate analysis, evaluating the progression of degenerative joint disease (DJD) in the treated and untreated coxofemoral joints, and determining whether or not triple pelvic osteotomy resulted in degenerative joint changes in the ipsilateral stifle and hock. Twelve dogs were treated unilaterally and nine dogs were treated bilaterally with triple pelvic osteotomies. There were no differences in mean anteversion angles, angles of inclination, or preoperative DJD between treated hips and untreated hips. Degenerative joint disease progressed significantly in all hips regardless of treatment. Two cases developed hyperextension of their hocks after the triple pelvic osteotomies. However, no radiographic evidence of DJD was observed for any of the stifles or hocks at any observation time. A significant increase in vertical peak force (VPF) scores was noted for treated legs by two-to-three months after surgery, which continued over time. Untreated legs did not show a significant change in VPF scores over time. No differences were found in progression to higher scores when unilaterally treated legs, first-side treated legs, and second-side treated legs were compared

RESULTS: At 24 weeks post-injection, the patient had...... statistically significant cartilage and meniscus growth on MRI, as well as increased range of motion and decreased modified VAS pain scores. CONCLUSION: The described process of autologous mesenchymal stem cell culture and percutaneous injection into a knee with symptomatic and radiographic degenerative joint...

  16. Degenerative joint disease on MRI and physical activity: a clinical study of the knee joint in 320 patients

    We examined 320 patients with MRI and arthroscopy after an acute trauma to evaluate MRI in diagnosis of degenerative joint disease of the knee in relation to sports activity and clinical data. Lesions of cartilage and menisci on MRI were registered by two radiologists in consensus without knowledge of arthroscopy. Arthroscopy demonstrated grade-1 to grade-4 lesions of cartilage on 729 of 1920 joint surfaces of 320 knees, and MRI diagnosed 14 % of grade-1, 32 % of grade-2, 94 % of grade-3, and 100 % of grade-4 lesions. Arthroscopy explored 1280 meniscal areas and showed degenerations in 10 %, tears in 11.4 %, and complex lesions in 9.2 %. Magnetic resonance imaging was in agreement with arthroscopy in 81 % showing more degenerations but less tears of menisci than arthroscopy. Using a global system for grading the total damage of the knee joint into none, mild, moderate, or severe changes, agreement between arthroscopy and MRI was found in 82 %. Magnetic resonance imaging and arthroscopy showed coherently that degree of degenerative joint changes was significantly correlated to patient age or previous knee trauma. Patients over 40 years had moderate to severe changes on MRI in 45 % and patients under 30 years in only 22 %. Knee joints with a history of trauma without complete structural or functional reconstitution showed marked changes on MRI in 57 %, whereas stable joints without such alterations had degenerative changes in only 26 %. There was no correlation of degenerative disease to gender, weight, type, frequency, and intensity of sports activity. Therefore, MRI is an effective non-invasive imaging method for exact localization and quantification of chronic joint changes of cartilage and menisci that recommends MRI for monitoring in sports medicine.

  17. Age-related changes in the temporomandibular joint of the senescence accelerated mouse. SAM-P/3 as a new murine model of degenerative joint disease.

    Chen, W. H.; Hosokawa, M.; Tsuboyama, T.; Ono, T.; Iizuka, T; Takeda, T.

    1989-01-01

    Age-related changes of the condyle of the temporomandibular joint (TMJ) in strains of Senescence Accelerated Mouse (SAM) were investigated. With advancing age, all strains of SAM showed degenerative joint disease initiated by degenerative changes such as eg, roughness, fissure, and erosion on the condylar surface. These degenerative changes were in concert with an active remodeling that can lead to deformation of the condyle. Moreover, the short-lived SAM-P (accelerated senescence prone mouse...

  18. Radiological and Radionuclide Imaging of Degenerative Disease of the Facet Joints

    The facet joint has been increasingly implicated as a potential source of lower back pain. Diagnosis can be challenging as there is not a direct correlation between facet joint disease and clinical or radiological features. The purpose of this article is to review the diagnosis, treatment, and current imaging modality options in the context of degenerative facet joint disease. We describe each modality in turn with a pictorial review using current evidence. Newer hybrid imaging techniques such as single photon emission computed tomography/computed tomography (SPECT/CT) provide additional information relative to the historic gold standard magnetic resonance imaging. The diagnostic benefits of SPECT/CT include precise localization and characterization of spinal lesions and improved diagnosis for lower back pain. It may have a role in selecting patients for local therapeutic injections, as well as guiding their location with increased precision

    Whole-body bone scintigraphy (or bone scan) is a highly sensitive method for visualizing bone metastases and is the accepted standard imaging modality for detection of metastases and assessment of treatment outcomes. The development of a quantitative biomarker using computer-aided detection on bone scans for treatment response assessment may have a significant impact on the evaluation of novel oncologic drugs directed at bone metastases. One of the challenges to lesion segmentation on bone scans is the non-specificity of the radiotracer, manifesting as high activity related to non-malignant processes like degenerative joint disease, sinuses, kidneys, thyroid and bladder. In this paper, we developed an automated bone scan lesion segmentation method that implements intensity normalization, a two-threshold model, and automated detection and removal of areas consistent with non-malignant processes from the segmentation. The two-threshold model serves to account for outlier bone scans with elevated and diffuse intensity distributions. Parameters to remove degenerative joint disease were trained using a multi-start Nelder-Mead simplex optimization scheme. The segmentation reference standard was constructed manually by a panel of physicians. We compared the performance of the proposed method against a previously published method. The results of a two-fold cross validation show that the overlap ratio improved in 67.0% of scans, with an average improvement of 5.1% points.

  1. Primary degenerative joint disease of the shoulder in a colony of Beagles

    Shoulder joints of 149 Beagles over 8 years old at the time of death (mean age, 13.8 years +/- 3.21), were examined radiographically throughout their life-times for the frequency of degenerative joint disease (DJD). Clinical histories revealed no underlying cause for DJD. The shoulder joints of a subgroup of 18 dogs were examined at necropsy, and thin sections of the joints were evaluated radiographically and histologically. Serial clinical radiographic studies indicated that normal shoulder joint development during the first year of life was followed by the appearance of subchondral bone sclerosis and bony remodeling of normal joint contour, and by the formation of periarticular osteophytes and enthesiophytes. All changes were progressive with age and typical for DJD in dogs. Bilateral involvement was common. Evaluation of specimens obtained at necropsy revealed: articular cartilage change with roughening of the surface layer, degeneration and death of superficial chondrocytes, exposure of deeper layers of chondrocytes that had proliferated with fissuring of the damaged cartilage, total cartilage loss with polishing of the exposed subchondral bone, mixed patterns of subchondral bone sclerosis and osteoporosis, change in contour of the articular surfaces, and formation of periarticular osteophytes and enthesiophytes. Joint capsule thickening, synovitis, pannus formation, and synovial chondroma formation were observed. Because of the available clinical information, in addition to the typical changes of DJD, it was thought that the changes were primary. Instability appeared to play a role in the pathogenesis of the joint disease described; however, it was not clear whether the instability caused abnormal forces on healthy cartilage or whether the primary cartilage wear caused the instability

  2. Evaluation of risk factors for degenerative joint disease associated with hip dysplasia in dogs

    Passive coxofemoral joint laxity of dogs, as quantitated by a distraction-stress radiographic method, may have important prognostic value in determining susceptibility to hip dysplasia. Data from 151 dogs, representing 13 breeds, were included in a logistic regression model to evaluate the contribution of factors such as age, breed, weight, sex, distraction index, and Norberg angle to the risk of developing degenerative joint disease (DJD) of the coxofemoral joint. Of the factors studied, the amount of passive hip laxity, as quantitated by the distraction index, was the most significant (P < 0.0001) determinant of the risk to develop DJD of the coxofemoral joint. In the longitudinal and cross-sectional components of the study, distraction index was a significant (P < 0.001) risk factor for DJD, irrespective of age at evaluation (4, 12, or 24 months). The strength of the hip laxity:DJD correlation increased with the age of dog. In contrast, the Norberg angle, a measure of hip laxity on the standard hip-extended radiograph, was not found to be a significant risk factor for DJD, either in the longitudinal or cross-sectional analyses. Breed-specific probability curves of DJD susceptibility indicated that German Shepherd Dogs had a significantly (P < 0.05) greater risk of developing DJD than did the pool of non-German Shepherd Dogs. The information derived from this statistical model will help to scientifically characterize the role of passive hip laxity as a component in the pathogenesis of DJD of the coxofemoral joint

  3. Usefulness of pinhole collimator in differential diagnosis of metastatic disease and degenerative joint disease in the vertebrae

    In order to evaluate the diagnostic efficacy of pinhole collimator (PHC) imaging combined with an X-ray for vertebral metastasis, our prospective study has employed receiver operating characteristics (ROC) analysis in 21 patients, 11 with osseous metastasis and 15 with degenerative joint disease in the lumbar vertebrae. PHC imaging provided better anatomic information on the extent of 99mTc-MDP accumulation. PHC vertebral scintigraphy had a considerable impact on the decision-making process, although with variations and not very satisfactory results among the physicians with little experience. Our study suggests that PHC imaging and X-ray film are useful in differentiating between osseous metastasis and degenerative joint disease in the vertebra. (author)

  4. Differential diagnosis between osseous metastasis and degenerative joint disease of the vertebrae by bone SPECT

    To find whether or not bone SPECT can differentiate osseous metastasis from degenerative joint disease (DJD) of the vertebrae, 43 patients with increased vertebral uptake on bone scan, including 25 lesions with bone metastasis, 24 with DJD, and 4 with compression fractures due to osteoporosis, underwent bone planar scanning and SPECT. Increased accumulation in the vertebral lesions on bone SPECT transaxial images was classified into five accumulation patterns; mosaic, large hot, diffuse, peripheral and articular patterns. Mosaic, large hot and diffuse patterns were more frequently noted in patients with osseous metastasis (82%, 67% and 62%, respectively). On the other hand, 80% of the lesions with peripheral pattern and 70% of those with articular pattern were ascribed to DJD. In conclusion, bone SPECT provided much better anatomic information on the extent of 99mTc-methylene diphosphonate(MDP). Differential diagnosis between osseous metastasis and DJD of the vertebrae may be improved by bone SPECT. (author)

  5. MR and MR arthrography to identify degenerative and posttraumatic diseases in the shoulder joint

    MR imaging provides a comprehensive evaluation of a wide spectrum of both intraarticular and extraarticular pathology of the shoulder. MR imaging enables the detection or exclusion of degenerative and posttraumatic diseases of the shoulder with a reasonable accuracy. MR arthrography is useful in the visualization of subtle anatomic details and further improves the differentiation. In this article, findings of MR imaging and MR arthrography of degenerative and posttraumatic shoulder diseases (impingement syndrome, rotator cuff tears, and glenohumeral instability) has been reviewed

  6. Imaging of bone spavin. A radiographic and scintigraphic study of degenerative joint disease in the distal tarsus in Icelandic horses

    Radiography and scintigraphy are commonly used for the diagnosis of skeletal disorders in horses. Icelandic Horses have a high prevalence of degenerative joint disease of the distal tarsus, generally known as bone spavin (BS). The purpose of this study was to evaluate and develop the use of radiography and scintigraphy for the detection of BS in Icelandic Horses

  7. Pathophysiology of Degenerative Disc Disease

    Choi, Yong-Soo

    2009-01-01

    The intervertebral disc is characterized by a tension-resisting annulus fibrosus and a compression-resisting nucleus pulposus composed largely of proteoglycan. The most important function of the annulus and nucleus is to provide mechanical stability to the disc. Degenerative disc disease in the lumbar spine is a serious health problem. Although the three joint complex model of the degenerative process is widely accepted, the etiological basis of this degeneration is poorly understood. With th...

  8. Long-Term Follow-Up of the Cheilectomy for Degenerative Joint Disease of the First Metatarsophalangeal Joint.

    Nicolosi, Nicole; Hehemann, Chris; Connors, James; Boike, Allan

    2015-01-01

    Cheilectomy is the surgical resection of 20% to 30% of the dorsal metatarsal head and proximal phalanx. The present retrospective study evaluated the long-term efficacy of aggressive cheilectomy to address degenerative joint disease of the first metatarsophalangeal joint. To our knowledge, this is the second longest duration study to date to evaluate the long-term efficacy of the cheilectomy procedure, with a mean follow-up period of 7.14 years (range 39 weeks to 14.87 years). The mean patient age was 55.71 ± 9.51 years, and 37 (65%) of the patients were female. Age, sex, foot type, and preoperative radiographic parameters of hallux rigidus were also evaluated and correlated. The mean percentage of success with this operation was 87.69%. Of the 58 patients, 51 (87.93%) experienced no limitations in their daily activities. Only 2 patients (3.33%) subsequently required subsequent arthrodesis. The results of the present study suggest that cheilectomy offers long-term satisfaction for patients with hallux rigidus and is an acceptable alternative to the joint destructive procedure of first metatarsophalangeal arthrodesis.

  9. Influence of spinal degenerative joint disease on BMD measurement by QCT and DXA

    Objective: To assess the impact of spinal degenerative joint disease (DJD) changes on bone mineral density (BMD) measured by quantitative CT (QCT) and dual X-ray absorptiometry (DXA) in a group of relative old population. Methods: Lateral (T4-L4) and anterior posterior (L1-L4) spinal radiographs in 201 subjects were reviewed for evaluation of fracture and DJD. The subjects ranged in age from 45-80 years (mean age 59.6 +- 0.8 years). Exclusion criteria included history of any bone disease or condition know to affect bone metabolism. The severity of DJD was graded as 0, 1 or 2 on the spinal lumbar film, except for DJD with vertebral osteophytes which was graded from 0 to 3. Twenty-five out of the 201 subjects were diagnosed with vertebral fractures by visual inspection using the semiquantitative method. Spinal BMD was measured by both QCT and DXA, including posteroanterior DXA (PA-DXA), lateral DXA (L-DXA), and mid lateral DXA (ML-DXA). Results: There were no significant differences in BMD measured by QCT in the 176 non-fractured subjects with and without DJD (P > 0.05). BMD measured by PA-DXA was significantly higher in subjects with DJD changes than those without, particularly when osteophytes were presented at the vertebral bodies and facet joints (P 0.05). Conclusion: QCT is superior to PA-DXA, L-DXA, and ML-DXA in detecting bone loss in patients with DJD. For subjects with severe DJD, BMD assessment using QCT may be advisable

  10. Effect of Age on the Hemostatic Function in Patients with Degenerative Diseases of the Large Joints

    Igor L. Shlykov, PhD¹, ScD¹

    2013-06-01

    Full Text Available Background: Aging is associated with an increased hypercoagulable state. Degenerative diseases of the large joints are also accompanied by increased coagulation activity. We investigated the effect of age on the hemostatic function in patients with osteoarthritis. Material and Methods: The study included 192 patients with osteoarthritis admitted to the clinic for primary hip or knee arthroplasty. The patients were categorized into 5 age groups: the age group under 40 years, the 41–to-50 -year age group, the 51–to-60-year age group, the 61-to-70- year age group, and the age group over 70 years. The general blood clotting tests, platelet number, fibrinogen, antithrombin, protein C, TAT, D-dimer, vonWillebrand factor (vWF, PAI-1, ß-thromboglobulin were determined. Results: Among patients with osteoarthritis, the antithrombin III level significantly decreased by the age of 50; however, above the age of 60 there was a distinct decrease in platelet count, and over the age of 70 the activity of the extrinsic coagulation pathway and the plasminogen level dropped significantly. TAT and D-dimer levels were elevated in most of the patients. Conclusion: The decrease in platelet count coupled with the activity of the extrinsic coagulation pathway in elderly osteoarthritic patients may increase blood loss during total arthroplasty; also, the drop in the anticoagulant and fibrinolytic potential may play a negative role in strengthening the prothrombotic state during the postoperative period.

  11. Functional interrelations between the lumbosacral, sacroiliac and coxofemoral complex in dogs as denoted by degenerative joint diseases

    Functional interrelations between coxofemoral joint, sacroiliac joint and the lumbosacral junction were investigated in Rottweilers, Golden Retriever and German Shepherd dogs. The study was based on sample of 120 ventrodorsal radiographs of the pelvis, which was assessed for evidence of hip dysplasia, alterations of the synovial and extrasynovial components of the sacroiliac joints, and osteophyte formation at the lumbosacral junction. Alteration of the extrasynovial component of the sacroiliac joint was the disease most commonly observed. Such degenerative alterations of the sacroiliac joint were noted to be associated with osteophyte formation at the lumbosacral junction. Both diseases were associated with age and German Shepherd dogs were most frequently affected. Results obtained by the additional evaluation of the coxofemoral joints suggest two mechanisms inducing degenerative alterations at the joint complex investigated. Based on changes in collagen composition, congenitally determined insufficiency of the supporting connective tissue may be responsible for the coincidence of alterations of all joint components of the lumbosacral - sacroilia - coxofemoral complex as noted in one group of dogs. In contrast, pre-dominant affection of the sacroiliac amphiarthosis and the lumbosacral intervertebral disc space is supposed to result from cumulative overloading. (author)

  12. Clinical cases of joint disease in horse. Total glycosaminoglycans sulphate and keratansulphate in synovial fluid as markers of degenerative cartilage processes

    Total glycosaminoglycans sulphate (GAGs) and keratan sulphate (KS) were measured in synovial fluid (SF) obtained from 28 horses with different joint diseases (degenerative joint disease (DJD), osteochondrosis (OCD), positivity to Flex Test (FT)) and 15 horses without any clinical sign of lameness. All groups of animals with joint disease showed levels of total GAGs significantly higher (P0.001) than normal. On the contrary, only DJD affected joints showed a significantly (P0.01) higher level of KS

  13. Imaging of degenerative and posttraumatic disease in the shoulder joint with ultrasound

    This article reviews the examination technique of shoulder ultrasound, normal and abnormal ultrasound findings in acute (posttraumatic) and chronic (degenerative) lesions. Moreover, it reviews the effectiveness of ultrasound in relation to magnetic resonance (MR) imaging. Most authors report that full-thickness tears of the supraspinatus can reliably be diagnosed by ultrasound. However, the simple diagnosis of a full-thickness rotator cuff tear is no longer sufficient for surgical management. The precise localization and size of rotator cuff tears as well as the extent of muscle degeneration is important for surgical planning. For this aspect and for partial-thickness tears of the supraspinatus, for subscapularis lesions as well as for lesions of the long biceps tendons there is no consensus regarding the diagnostic value of ultrasound. To the present, ultrasound (contrary to MR imaging) has failed to demonstrate that it consistently influences the clinician's degree of confidence in the clinical diagnosis or the treatment plan. Therefore, some orthopedic surgeons prefer MR imaging to ultrasound in the evaluation of rotator cuff tears and other abnormalities of the glenohumeral joint. Moreover, MR imaging, especially when combined with arthrography, represents a one-step investigation, which not only allows for assessment of rotator cuff lesion but also of lesions of the labrum (Bankart lesions, SLAP lesions), the joint capsule and the biceps tendon. It also demonstrates muscle atrophy, which represents an important predictor of surgical outcome in rotator cuff repair

  14. Chondroitin sulfate and sodium hialuronate in treatment of the degenerative joint disease in dogs. Clinical and radiological aspects

    The aim of this study was the evaluation of the effects of chondroitin sulfate and sodium hyaluronate in the knee joint of dogs with experimentally induced degenerative joint disease (DJD). Fifteen mongrel dogs, weighing 18 to 25kg were used. DJD was induced by cranial cruciate ligament (CCL) arthroscopical transection. After three weeks, CCL was repaired by an intrarticular technique, which uses fascia lata. The dogs were then divided into three groups as follows: group I received no other treatment, but the CCL reconstitution, group II received 24mg/animal of chondroitin sulfate/IM every five days, totaling six injections, and group III received 20mg/animal of sodium hyaluronate /IV every five days, totaling three injections. All dogs were examined clinically and radiographically for 90 days after the repairment surgery. The clinical evaluation was performed by assessment of lameness, weight-bearing, limb muscle atrophy and range of motion. The results demonstrated that the group treated with sodium hyaluronate had lower degree of lameness in comparison with other groups. The radiographic evaluation showed marginal osteophytes and subchondral bone sclerosis. These changes were more severe in the group treated with sodium hyaluronate. The better clinical results observed in this group, compared with the others, was probably due to the greater action of the drug in the synovium, decreasing the pain and lameness. Radiographic findings correlated poorly with the clinical signs in the group treated with sodium hyaluronate

    Degenerative disease of the spine is a definition that includes a wide spectrum of degenerative abnormalities. Degeneration involves bony structures and the intervertebral disk, although many aspects of spine degeneration are strictly linked because the main common pathogenic factor is identified in chronic overload. During life the spine undergoes continuous changes as a response to physiologic axial load. These age-related changes are similar to pathologic degenerative changes and are a common asymptomatic finding in adults and elderly persons. A mild degree of degenerative changes is paraphysiologic and should be considered pathologic only if abnormalities determine symptoms. Imaging allows complete evaluation of static and dynamic factors related to degenerative disease of the spine and is useful in diagnosing the different aspects of spine degeneration. PMID:17493541

    Full Text Available The aim of the investigation is to increase the efficiency of treatment of osteoarthrosis deformans of foot and ankle joints by developing and applying new hi-tech methods of treatment – individual replacement of the foot bones and joints. Materiales and Methods. 39 patients with the specified pathology were surveyed. Standard total ankle replacement was performed in two of them (STAR, W. Link, 16 patients underwent the first MTP joint replacement with Total toe system. In five cases with the 1st MTPJ arthrosis there was observed total, subtotal and polylocal aseptic necrosis of the head of the first metatarsal bone. 10 patients had a similar picture of damage of the talus due to trauma. For these patients individual artificial implants of the talus and endoprostheses of the first MTPJ were developed. Modern techniques (CT, MRT were used to early radiodiagnosis of posttraumatic talus damage. Results and Discussion. There were developed new methods of surgical treatment of such consequences of trauma of the talus as total, subtotal and polylocal aseptic necrosis — individual total replacement of the talus by original patented technique and replacement of the first MTP joint in cases of severe aseptic necrosis of the 1st metatarsal bone’s head with the implant with the long stem (when standard joint replacement is noneffective. Pre-production models of implants and tools were made, and technical tests of designs were carried out.

  17. Relationship between degenerative joint disease and hip joint laxity by use of distraction index and Norberg angle measurement in a group of cats

    Objective: To determine the relationship between degenerative joint disease (DJD) and passive laxity of the hip joint in a group of cats. Design: Prospective study. Animals: A select (nonrandomized) group of 78 cats. Procedure: Standard hip-extended radiographic views and compression and distraction views of the pelvis were obtained from cats during sedation. Radiographs were evaluated, using an Orthopedic Foundation for Animals (OFA)-like scoring system for dogs. Passive joint laxity was measured, using Norberg angle (NA) and distraction index (DI). Hip laxity in cats with DJD was compared with hip laxity in cats without DJD. Results: Hip dysplasia (HD) was subjectively diagnosed radiographically in 25 of 78 (32%) cats using the OFA-like scoring system. Nineteen cats had mild HD 4 had moderate HD, and 2 had severe HD. Fifteen of the 25 cats with HD had DJD. The NA ranged from 56 to 105. The mean NA in cats with DJD was (84 degrees) significantly lower than in cats without DJD (95 degrees). The DI ranged from 0.2 to 0.84. The mean DI for cats with DJD was (0.6) significantly higher than that for cats without DJD (0.49). Cats with a DI < 0.4 did not have DJD. Cats had an increased likelihood of having DJD with increased laxity in the coxofemoral joint, as measured by NA or DI. Clinical Implications: The mean NA for radiographically normal cats (92.4 degrees) was lower than that in radiographically normal dogs (103 degrees). The overall mean DI for cats in this group (0.51) is similar to dogs of breeds with high joint laxity, such as the Labrador Retriever (0.5). As in dogs, there is a relationship between DJD and laxity in the hip joint of cats

  18. Low back pain and degenerative disc disease

    Full Text Available Introduction. Various clinical conditions can cause low back pain, and in most cases it is of a degenerative origin. Degenerative disc disease is a common condition which affects young to middle-aged men and women equally. Changes in the mechanical properties of the disc lead to degenerative arthritis in the intervertebral joints, osteophytes, and narrowing the intervertebral foramen or the spinal canal. Pathophysiology. Degenerative cascade, described by Kirkaldy-Willis, is the widely accepted pathophysiologic model describing the degenerative process as it affects the lumbar spine in 3 phases. Diagnosis. There are two forms of low back pain secondary to degenerative disc disease: a lumbalgia and b lumbar radiculopathy. Limitation of movement, problems with balance, pain, loss of reflexes in the extremities, muscle weakness, loss of sensation or other signs of neurological damage can be found on physical examination. For accurate diagnosis, it is often necessary to combine clinical examination and sophisticated technology. Treatment. Coservative treatment consists of rest, physical therapy, pharmacological therapy and injection therapy. Physical rehabilitation with active patient participation is a key approach to treatment of patients with discogenic pain. Physical therapy, occupational therapy and kinesitherapy are important for improving muscle strength, endurance, and flexibility. Disc surgery is performed if surgical intervention is required. .

  19. Degenerative Achilles tendon disease

    As Magnetic Resonance (MR) imaging and Ultrasound (US) allow the evaluation of soft-tissue structures not previously possible with other imaging techniques, a clinical study has been undertaken to determine the value of these 2 modalities in the detection of lesions in the Achilles tendon (AT), other than acute total rupture. Seven healthy subjects and 28 symptomatic patients with Achillodynia and/or signs of thickening of the AT were investigated with MR and US; all results were compared with the clinical features. Surgical findings were available in 14 patients. Patients were divided into 3 groups; those with tendon thickening, incomplete and complete ruptures. Thickening of the AT was easily detected with both methods. MR was superior in the detection of incomplete tendon rupture and in the evaluation of various stages of chronic degenerative changes. It is concluded that only if US remains unclear, an additional MR study should be performed and together with the clinical diagnosis indication for surgery can be made more efficient.

  20. A radiological study on the degenerative joint disease of the lumbar spine in Korean adult men below the age of forty

    It is generally believed that this disease is a degenerative process, a part of the general phenomena, hastened by excessive functional demand and a decreasing efficiency of blood supply. Though degenerative joint disease is the commonest of all ailments, its manifestations do not appear as a rule until the fourth or fifth decade, and it is not always easy to diagnose because we know less about it than about many less common types. Little information is available on its frequency in person below the age of forty. The present study was designed to obtain more precise information about development of this disease in person below the age of forty. After a detailed clinical examination, x-ray findings of a total of 566 men with low back pain checked at the Department of Radiology, National Public Hospital from Jan. 1976 to Dec. 1978 were received. The following result were obtained: 1. 111 (19.6%) of the 566 men had radiologic evidence of degenerative disease in lumbar spine. The degenerative joint disease first appeared on the age of 26. The degenerative joint disease was found in 16 (14.9%) of the 107 men between 25 and 29 years old, 14 (16.3%) of the 86 men between 35 and 39 years old, 31 (27.4%) of the 113 men between 35 and 39 years old, and 50 (50%) of the 100 between 40 and 44 years old. 2.The 4th lumbar spine was most commonly involved, being in 82.0% of the cases, and less frequent sites were the 5th lumbar spine (67.6%), the 3rd lumbar spine (51.3%), the 2nd lumbar spine (18.9%) and the 1st lumbar spine (3.6%). 38 (28.8%) of the 111 cases revealed single level involvement, but 79 (71.2%) cases showed multiple level involvement with the highest incidence at 14 and 15. 3. 111 cases of the 566 revealed marginal spurring. Bridging was noted in 8 cases, space narrowing 8 cases, and eburnation 7 caes.

  1. Degenerative disease of the spine

    With few exceptions, magnetic resonance imaging (MRI) is becoming the modality of choice for the evaluation of degenerative disorders of the entire spine. With the implementation of surface coils and continued refinement and development of new pulse sequences, osseous and soft tissue structures of the spine can now be studied in great detail. The introduction of paramagnetic contrast agents has made it possible to differentiate epidural scar from recurrent disc herniation in the postoperative setting and to discern previously undetected degenerative changes within the intervertebral disc itself. This paper discusses the spectrum of degenerative diseases of the spine, including disc degeneration (intervertebral osteochondrosis), disc herniation, spinal stenosis, spondylosis deformans, and osteoarthritis. A brief description of the MR techniques and strategies used to evaluate these disorders is also

  2. Joint diseases

    The authors discuss how x-ray examination is essential in the diagnosis and evaluation of the arthritides. Most arthritides are first suspected by the clinician, and x-ray evaluation of these entities along with laboratory testing is important for confirmation of the clinical diagnosis and in staging of the disease process. Several arthritides are often diagnosed first by the podiatrist on x-ray evaluation, including pseudogout, ankylosing spondylitis, early rheumatoid arthritis, degenerative joint disease, and tuberculosis of bone. The joint responds to insult in only a limited number of ways that become apparent on x-ray. The soft tissues surrounding the joint, the articulating bones, and alignment of the joint space may all be involved by the arthritic process. On roentgenographic examination, the soft tissues must be examined for edema, masses, calcifications, and atrophy. The articulating bones must be examined for demineralization, erosions, osteophytes, periosteal reaction, cysts and sclerosis

  3. Computerized tomography in the diagnosis of degenerative vertebral diseases

    CT and roentgenography were used for the investigation of 78 patients with the radicular syndrome. The state of the intervertebral disks, intervertebral joints and cerebrospinal canal in degenerative vertebral diseases was assessed. CT permits the detection of hernia, protrusion of the intervertebral disks, deformity of the intervertebral joints, and the narrowing of the cerebrospinal canal as a result of degenerative changes, as well as establishing the cause of the affection of neural structures in the cerebrospinal canal, radicular holes. CT possesses some advantages over roentgenography in the diagnosis of degenerative vertebral diseases

  5. New Aspects of Correlation of Free Radical Oxidation and the Severity of Pathological Process in Congenital Dislocated Hip and Degenerative Dystrophic Diseases of Hip Joint in Children

    Strelkova I.G.

    2012-12-01

    Full Text Available The aim of the investigation is to prove the correlation of free radical processes and the state of anti-oxidant system, and the severity of pathological process in children with congenital dislocated hip. Materials and Methods. There were examined 143 patients with congenital dislocated hip aged from 4 to 17 years, they were divided into three groups: the 1st group (n=39 — children with noncomplicated disease, the 2nd group (n=47 — children with coxarthrosis, the 3rd group (n=32 — children with Legg’s disease. The control group (n=161 included virtually healthy children. The investigations of free radical production level and the condition of anti-oxidant system were carried out in patients’ blood serum, plasma, and erythrocytes. Results. There was revealed statistically significant correlation between the intensity of lipid peroxidation and the degree of manifestation of dystrophic changes in an affected joint. There was registered the activation of anti-oxidant protection systems in children suffering from hip joint pathology due to the necessity of limitation of free radical processes intensity and their maintenance at an adequate level. Conclusion. The indices of lipid peroxidation intensity and anti-oxidant enzymes activity as diagnostic criteria enable to estimate the depth of pathological changes in children with congenital dislocated hip and degenerative and dystrophic diseases of hip joints, and timely perform effective therapeutic interventions to prevent the deformity of femoral head.

  6. Neuro degenerative diseases: clinical concerns

    Idiopathic Parkinson's disease (PD) and Alzheimer's disease (AD) are the main neuro-degenerative diseases (NDDs) seen clinically. They share some common clinical symptoms and neuro-pathological findings. The increase of life expectancy in the developed countries will inevitably contribute to enhance the prevalence of these diseases. Behavioral disorders, common in NDDs, will produce major care management challenges. Idiopathic Parkinson's disease corresponds to a histopathological diagnosis, based on the observation of a de-pigmentation and a neuronal loss in the substantia nigra, as well as on the presence of intra-neuronal inclusion bodies. AD is insidious with slowly progressive dementia in which the decline in memory constitutes the main complaint. The diagnosis of definite AD requires the presence of clinical criteria as well as the histopathological confirmation of brain lesions. The two main lesions are the presence of senile plaques and neuro-fibrillary tangles. Positron emission tomography (PET) explores cerebral metabolism and neurotransmitter kinetics in NDDs using principally [18F]-deoxyglucose and [18F]-dopa. Nigrostriatal dopaminergic function is altered in PD, as evidenced by the low uptake of [18F]-dopa in the posterior putamen as compared to anterior putamen and caudate nucleus. In contrast, [18F]-dopa uptake is equally depressed in all striatal structures in progressive supra-nuclear palsy. Regional glucose metabolism at rest is preserved in elderly once cerebral atrophy is taken into account. On the contrary, glucose metabolism is globally reduced in AD, with marked decrease in the parietal and temporal regions. PET has proved to be useful to study in vivo neurochemical processes in patients suffering from NDDs. The potential of this approach is still largely unexploited, and depends on new ligand production to establish early diagnosis and treatment follow-up. (author)

    Full Text Available Background:: Degenerative Joint Disease (DJD is the most common joint disease in human beings. Previous studies have explained that glucosamine is preferred as placebo and in efficacy compared with NSAIDs in treatment of patients knee osteoarthritis. Alendronate was used to treat osteoporotic patients and its efficacy was established..Objectives:: The aim of this study was to compare the efficacy of administration of glucosamine alone and its combination with alendronate in osteoarthritis of the knee..Patients and Methods:: The study included 130 patients with osteoarthritis who randomly received glucosamine alone (group II (500mg TDS, or combination of glucosamine (500mg TDS and alendronate (70mg weekly (group I for 12 weeks. Patients were evaluated on 1, 3, 6 and 12 weeks after beginning the treatment to evaluate efficacy of each treatment..Results:: Statistically, there was no significant difference in pain index (P > 0.05 but in the two groups the mean of pain index decreased in a similar fashion. The stiffness index in combination treatment group (group I decreased more than glucosamine group (group II (P < 0.05. The function of joints in combination treatment group (group I improved after 12weeks. The bone mineral density (BMD at 12weeks in combination therapy group improved..Conclusions:: Combination therapy of glucosamine and alendronate indicated significant improvement of stiffness, function, BMD of osteoarthritis compared with glucosamine alone but there was no statistically significant decrease in pain index. It can be concluded that the combination of glucosamine and alendronate provide better and more rapid improvement in patients with osteoarthritis.

  8. Study of the lateral raise in foot wear for the management of medial compartment degenerative joint disease of knee

    A wide spread disease, which may lead the patient to severe outcomes e.g. pain, loss of joint motion, inflexibility and even disability, is Knee osteoarthritis (OA). It is most common among adults of older age and should not be ignored at all. Literature does not show any clear pathogenesis for occurrence of Knee OA, but most of the indications point toward biomechanical stresses which may influence the articular cartilage and sub chondral bone. Objective: The Aim of this study is to become aware of the effects of physical therapy with and without laterally raised footwear in the management of medial knee osteoarthritis. Methodology: We have used experimental comparative study in 35 patients which were randomly selected from Department of Physiotherapy, Fatima Memorial Hospital, Shadman, Lahore. The study consisted of 2 groups, Group I (Experimental Group): In experimental group, patients were treated with laterally raised foot wear and physical therapy both. Group II (Control Group): Whereas in control group patients were treated by physical therapy alone. Kellgren and Lawrence (KL) scale was used to assess radiograph of the knee joints after an anteroposterior weight-bearing standing. The assessment of disease in patients was done by using the Western Ontario and McMaster Universities (WOMAC) Index, Muscle flexibility, Muscle strengthening and Tolerance scales. Results: In group-I the mean age of patients observed was 59.52+-13.66 years and 65+-12.87 years in Group-II. In Group-I, 9 (52.9%) patients were males and 8 (47.1%) patients were females while in Group-II, 9 patients (50%) were male and 9 (50%) were female. In Group-I 2 (11.8%) patients used flat and open shoes, 6 (35.3%) used flat and close shoe, 3 (17.6%) patients used dress shoes and 2 (11.8%) used flat shoes. In Group-I, the frequency of patients wearing laterally raised foot wear in terms of duration was; 5 (29.4%) patients for 20 days, 4 (23.5%) for 24 days, 4 (23.5%) for 25 days, whilst 2 patients used it for 26 and 30 days respectively. Among 10 (58.8%) patients the use of lateral raised foot wear was intermittent wile in 7 (41.2%) patients the use of lateral raised foot wear was continuous. Overall Group-I presented better results compared to Group-II in this study. Conclusion: We have concluded in our study that the physical therapy with laterally raised footwear is a successful treatment in the management of medial knee OA. In laterally raised footwear the physical therapy is an effective method in terms of relief of pain in patient, improvement in function by stiffness reduction and. this treatment method is recommended for the management of medial knee OA.

  9. Diagnostic dilemma of degenerative joint disease, chronic avascular necrosis or metastasis in planar Tc-99m-methylene diphosphonate planar skeletal scintigraphy excluded by single positron emission computed tomography/computed tomography

    We present a 71-year-old male patient subjected to skeletal scintigraphy for metastasis work up of prostate cancer. Whole body planar images revealed a solitary focal tracer uptake in left femoral head mimicking as solitary metastatic focus. Single positron emission computed tomography/computed tomography images localized this increased tracer uptake to the subchondral cysts with minimal sclerosis in left femur head with no decrease in size of femur head and was reported as (degenerative joint disease)

  10. Surgical removal of fragmented coronoid processes and fractured anconeal process in an older dog with evidence of severe degenerative joint disease

    A 10-year-old Labrador Retriever was admitted because of severe unilateral (left) forelimb lameness of 6 weeks' duration. Computerized tomography revealed bilateral fragmented coronoid processes (FCP) and unilateral fracture of the anconeal process. Surgery on the left elbow to remove the loose anconeal process and FCP resolved the severe lameness and improved the dog's overall activity, compared with that of the preceding 2 years. Unstable FCP can develop late in life, and a degenerative anconeal process may fracture. Surgical removal of loose fragments in a severely arthritic joint may be beneficial

  11. Inter-examiner reliability of the diagnosis of cervical pillar hyperplasia (CPH and the correlation between CPH and spinal degenerative joint disease (DJD

    2003-12-01

    Full Text Available Abstract Background Cervical pillar hyperplasia (CPH is a recently described phenomenon of unknown aetiology. Its clinical importance is poorly understood at the present time; therefore, the objective of this study was to determine (1 the inter-examiner reliability of detecting CPH and (2 if there is a clinically important correlation (r > 0.4 between the number of cervical spine levels showing signs of degenerative joint disease (DJD and CPH. Methods The sample consisted of 320 radiographs of human male and female subjects who ranged from 40 to 79 years of age. The inter-examiner reliability of assessing the presence/absence of pillar hyperplasia was evaluated on 50 neutral lateral radiographs by two examiners using line drawings and it was quantified using the kappa coefficient of concordance. To determine the presence/absence of hyperplastic pillars as well as the presence/absence of DJD at each intervertebral disc and zygapophysial joint, 320 AP open mouth, AP lower cervical and neutral lateral radiographs were then examined. The unpaired t-test at the 5% level of significance was performed to test for a statistically significant difference between the number of levels affected by DJD in patients with and without hyperplasia. The Spearman's rho at the 5% level of significance was performed to quantify the correlation between DJD and age. Results The inter-examiner reliability of detecting cervical pillar hyperplasia was moderate with a kappa coefficient of 0.51. The unpaired t-test indicated that there was no statistically significant difference (p > 0.05 between the presence/absence of cervical pillar hyperplasia and the number of levels affected by DJD in an age-matched population, regardless of whether all elements were considered together, or the discs and facets were analyzed separately. A Spearman correlation rank of 0.67 (p Conclusion Cervical pillar hyperplasia is a reasonable concept that requires further research. Its evaluation is easy to learn and acceptably reliable. Previous research has suggested that CPH may affect the cervical lordosis, and therefore, alter biomechanics which may result in premature DJD. This current study, however, indicates that, globally, CPH does not appear to be related to the development of DJD.

  14. Physiochemical basis of human degenerative disease

    Zeliger Harold I.

    2015-03-01

    Full Text Available The onset of human degenerative diseases in humans, including type 2 diabetes, cardiovascular disease, neurological disorders, neurodevelopmental disease and neurodegenerative disease has been shown to be related to exposures to persistent organic pollutants, including polychlorinated biphenyls, chlorinated pesticides, polybrominated diphenyl ethers and others, as well as to polynuclear aromatic hydrocarbons, phthalates, bisphenol-A and other aromatic lipophilic species. The onset of these diseases has also been related to exposures to transition metal ions. A physiochemical mechanism for the onset of degenerative environmental disease dependent upon exposure to a combination of lipophilic aromatic hydrocarbons and transition metal ions is proposed here. The findings reported here also, for the first time, explain why aromatic hydrocarbons exhibit greater toxicity than aliphatic hydrocarbons of equal carbon numbers.

  16. TU-C-12A-12: Differentiating Bone Lesions and Degenerative Joint Disease in NaF PET/CT Scans Using Machine Learning

    Purpose: [F-18]NaF PET can be used to image bone metastases; however, tracer uptake in degenerative joint disease (DJD) often appears similar to metastases. This study aims to develop and compare different machine learning algorithms to automatically identify regions of [F-18]NaF scans that correspond to DJD. Methods: 10 metastatic prostate cancer patients received whole body [F-18]NaF PET/CT scans prior to treatment. Image segmentation resulted in 852 ROIs, 69 of which were identified by a nuclear medicine physician as DJD. For all ROIs, various PET and CT textural features were computed. ROIs were divided into training and testing sets used to train eight different machine learning classifiers. Classifiers were evaluated based on receiver operating characteristics area under the curve (AUC), sensitivity, specificity, and positive predictive value (PPV). We also assessed the added value of including CT features in addition to PET features for training classifiers. Results: The training set consisted of 37 DJD ROIs with 475 non-DJD ROIs, and the testing set consisted of 32 DJD ROIs with 308 non-DJD ROIs. Of all classifiers, generalized linear models (GLM), decision forests (DF), and support vector machines (SVM) had the best performance. AUCs of GLM (0.929), DF (0.921), and SVM (0.889) were significantly higher than the other models (p<0.001). GLM and DF, overall, had the best sensitivity, specificity, and PPV, and gave a significantly better performance (p<0.01) than all other models. PET/CT GLM classifiers had higher AUC than just PET or just CT. GLMs built using PET/CT information had superior or comparable sensitivities, specificities and PPVs to just PET or just CT. Conclusion: Machine learning algorithms trained with PET/CT features were able to identify some cases of DJD. GLM outperformed the other classification algorithms. Using PET and CT information together was shown to be superior to using PET or CT features alone. Research supported by the Prostate Cancer Foundation

The objective of this work was to evaluate pain relief, improvement of joint function, muscular rehabilitation and instability progression in 10 dysplasic dogs submitted to the hi [...] p joint denervation technique. The grading of the clinical presentation was performed according to specific evaluation of walking, biped station, rotation with external abduction, subluxation and iliopsoas. The muscular rehabilitation was evaluated through the circumference of the thigh and physical examination. The instability was evaluated through the values of distraction index (DI). In the claudication graduation and the biped station test, we verified that there was a significant reduction after one month post-surgery. In the abduction with external rotation tests, there was a reduction in pain after the seventh day; in the iliopsoas test there was a significant reduction in pain in all the post-surgery times. There was a significant increase in thigh circumference after the seventh day. We observed that 90% of the articulations had a reduction in their DI, reflecting an improvement of their instability. The technique is efficient in the relief of pain, muscular rehabilitation after the improvement of the ability to exercise, and in reduction of instability, being the cause of owner satisfaction.

  1. The sternoclavicular joint: can imaging differentiate infection from degenerative change?

    The purpose of this study was to determine if there are imaging and clinical findings that can differentiate a septic sternoclavicular joint from a degenerative one. Search of radiology reports from 2000-2007 revealed 460 subjects with imaging of the sternoclavicular joint, of whom 38 had undergone aspiration or biopsy. The final study group consisted of nine subjects with pathologic proof of sternoclavicular joint infection and ten subjects with pathologic and clinical findings excluding infection consistent with degenerative change. Available ultrasound, computed tomography (CT), and magnetic resonance (MR) images were retrospectively reviewed, and echogenicity, capsular distention, erosions, cysts, hyperemia or enhancement, and intensity of bone marrow signal were recorded. Clinical data were also reviewed. The findings significantly associated with sternoclavicular joint infection included degree and extent of capsular distention. With infection, average joint distention was 14 mm (range 10-20 mm) and extended over the sternum and clavicle in 60% compared to 5 mm (range 3-8 mm) with degeneration only extending over the clavicle. Other findings significantly associated with infection included bone marrow fluid signal on magnetic resonance imaging (MRI), elevated Westergren red blood cell sedimentation rate, and fever. The two findings significantly associated with degeneration were subchondral cysts on CT and female gender. Other imaging and clinical variables showed no significant differences between infection and degenerative change. The clinical and imaging findings significantly associated with sternoclavicular joint infection included joint capsule distention of 10 mm or greater, extension over both the clavicle and sternum, adjacent fluid signal bone marrow replacement, elevated Westergren red blood cell sedimentation rate, and fever.

  5. Stem cell treatment of degenerative eye disease

    2015-05-01

    Full Text Available Stem cell therapies are being explored extensively as treatments for degenerative eye disease, either for replacing lost neurons, restoring neural circuits or, based on more recent evidence, as paracrine-mediated therapies in which stem cell-derived trophic factors protect compromised endogenous retinal neurons from death and induce the growth of new connections. Retinal progenitor phenotypes induced from embryonic stem cells/induced pluripotent stem cells (ESCs/iPSCs and endogenous retinal stem cells may replace lost photoreceptors and retinal pigment epithelial (RPE cells and restore vision in the diseased eye, whereas treatment of injured retinal ganglion cells (RGCs has so far been reliant on mesenchymal stem cells (MSC. Here, we review the properties of non-retinal-derived adult stem cells, in particular neural stem cells (NSCs, MSC derived from bone marrow (BMSC, adipose tissues (ADSC and dental pulp (DPSC, together with ESC/iPSC and discuss and compare their potential advantages as therapies designed to provide trophic support, repair and replacement of retinal neurons, RPE and glia in degenerative retinal diseases. We conclude that ESCs/iPSCs have the potential to replace lost retinal cells, whereas MSC may be a useful source of paracrine factors that protect RGC and stimulate regeneration of their axons in the optic nerve in degenerate eye disease. NSC may have potential as both a source of replacement cells and also as mediators of paracrine treatment.

    Biomedical advances in vision research have been greatly facilitated by the clinical accessibility of the visual system, its ease of experimental manipulation, and its ability to be functionally monitored in real time with noninvasive imaging techniques at the level of single cells and with quantitative end-point measures. A recent example is the development of stem cell-based therapies for degenerative eye diseases including AMD. Two phase I clinical trials using embryonic stem cell-derived RPE are already underway and several others using both pluripotent and multipotent adult stem cells are in earlier stages of development. These clinical trials will use a variety of cell types, including embryonic or induced pluripotent stem cell-derived RPE, bone marrow- or umbilical cord-derived mesenchymal stem cells, fetal neural or retinal progenitor cells, and adult RPE stem cells-derived RPE. Although quite distinct, these approaches, share common principles, concerns and issues across the clinical development pipeline. These considerations were a central part of the discussions at a recent National Eye Institute meeting on the development of cellular therapies for retinal degenerative disease. At this meeting, emphasis was placed on the general value of identifying and sharing information in the so-called "precompetitive space." The utility of this behavior was described in terms of how it could allow us to remove road blocks in the clinical development pipeline, and more efficiently and economically move stem cell-based therapies for retinal degenerative diseases toward the clinic. Many of the ocular stem cell approaches we discuss are also being used more broadly, for nonocular conditions and therefore the model we develop here, using the precompetitive space, should benefit the entire scientific community.

  7. Canine Degenerative Valve Disease: A Case Report

    Carmenza Janneth Benavides Melo

    2014-07-01

    Full Text Available Degenerative valvular disease or endocardiosis is the most common cardiovascular pathology in dogs. It is characterized by regurgitation of blood into the atria with decreased cardiac output, leading to volume overload with eccentric hypertrophy and congestive heart failure. This report describes the clinical and autopsy findings of a dog, suggestive of valvular endocardiosis. The patient was admitted to the outpatient Veterinary Clinic “Carlos Martínez Hoyos” at the University of Nariño (Pasto, Colombia. His owner said the dog was sick for two months, with signs of respiratory disease, weight loss, and decay. Clinical examination showed very pale mucous membranes, inspiratory dyspnea, rale, split S2, grade 4 mid-systolic murmur of regurgitation, and abdominal dilatation with sign of positive shock wave. Necropsy evidenced plenty of translucent watery material in the abdominal, chest and pericardium cavity, severely enlarged and rounded heart with thickened atrioventricular valves, moderate reduction in liver size and signs of lobulation, severely diminished and pale kidneys with irregular surface showing the presence of multiple cystic areas in corticomedullary region. Samples were taken from these tissues and fixed in 10% buffered formalin to be processed for histopathological analysis at the Laboratory of Pathology at the University of Nariño, using hematoxylin and eosin stain. This way, degenerative valvular disease was diagnosed.

    Retinal degenerative diseases are major causes of vision loss and blindness worldwide and are characterized by chronic and progressive neuronal loss. One common feature of retinal degenerative diseases and brain neurodegenerative diseases is chronic neuroinflammation. There is growing evidence that retinal microglia, as in the brain, become activated in the course of retinal degenerative diseases, having a pivotal role in the initiation and propagation of the neurodegenerative process.

  10. 3-D MRI for lumbar degenerative diseases

    Three-dimensional (3-D) magnetic resonance (MR) images obtained from 10 patients with lumbar degenerative diseases were retrospectively reviewed to determine how far 3-D MR imaging is capable of demonstrating nerve roots. In 8 of the 10 patients, the area up to the dorsal root ganglion was visualized on 3-D MR images. Thus, it is capable of detecting a wide area of nerve roots, thereby allowing the determination of running of nerve root, and size and location of dorsal root ganglion. In delineating the area from the dural canal to root cyst, 3-D MR imaging was equal to conventional myelography. The former was superior to the latter in detecting the positional relation between the degenerative intervertebral disc and the nerve root, and herniation-compressed root cyst. In 3 of 9 patients who presented with root symptoms, disturbed nerve roots were of high signal on 3-D MR images. This may suggest that it has the potential for selectively detecting root nerves associated with clinical manifestations. (N.K.)

  12. Computed tomography in lumbar degenerative disease

    We reported the 18 patients which underwent surgical exploration and reviewed these CT findings. Method All CT scans were obtained on Somatom II, high resolution CT scanner, with the patient in the supine position. A lateral localizer image (Topogram) was used to select the appropriate intervertebral disk space. The slice thickness was 4 mm. Results 1) CT findings in lumbar degenerative diseases include bony canal stenosis (central canal stenosis, narrowed lateral recess), soft tissue abnormalities (herniated nucleus pulposus, bulging annulus, hypertrophy and/or ossification of ligamentum flavum, no delineation of nerve root in lateral recess), and spinal instability (spondylolisthesis, vacuum phenomenon). 2) The above three factors contribute to narrowing of spinal canal. 3) No delineation of nerve root or soft tissue replacement of epidural fat in lateral recess suggests that the nerve root may be compressed by some factors. 4) Herniated nucleus pulposus may cause nerve root compression with or without canal stenosis. Conclusion This study revealed that the CT findings correlated closely with the surgical findings and the site of nerve root compression could be determined. (author)

  13. Sacroiliac joint motion in patients with degenerative lumbar spine disorders.

    OBJECT Usually additional anchors into the ilium are necessary in long fusion to the sacrum for degenerative lumbar spine disorders (DLSDs), especially for adult spine deformity. Although the use of anchors is becoming quite common, surgeons must always keep in mind that the sacroiliac (SI) joint is mobile and they should be aware of the kinematic properties of the SI joint in patients with DLSDs, including adult spinal deformity. No previous study has clarified in vivo kinematic changes in the SI joint with respect to patient age, sex, or parturition status or the presence of DLSDs. The authors conducted a study to clarify the mobility and kinematic characteristics of the SI joint in patients with DLSDs in comparison with healthy volunteers by using in vivo 3D motion analysis with voxel-based registration, a highly accurate, noninvasive method. METHODS Thirteen healthy volunteers (the control group) and 20 patients with DLSDs (the DLSD group) underwent low-dose 3D CT of the lumbar spine and pelvis in 3 positions (neutral, maximal trunk flexion, and maximal trunk extension). SI joint motion was calculated by computer processing of the CT images (voxel-based registration). 3D motion of the SI joint was expressed as both 6 df by Euler angles and translations on the coordinate system and a helical axis of rotation. The correlation between joint motion and the cross-sectional area of the trunk muscles was also investigated. RESULTS SI joint motion during trunk flexion-extension was minute in healthy volunteers. The mean rotation angles during trunk flexion were 0.07° around the x axis, -0.02° around the y axis, and 0.16° around the z axis. The mean rotation angles during trunk extension were 0.38° around the x axis, -0.08° around the y axis, and 0.08° around the z axis. During trunk flexion-extension, the largest amount of motion occurred around the x axis. In patients with DLSDs, the mean rotation angles during trunk flexion were 0.57° around the x axis, 0.01° around the y axis, and 0.19° around the z axis. The mean rotation angles during trunk extension were 0.68° around the x axis, -0.11° around the y axis, and 0.05° around the z axis. Joint motion in patients with DLSDs was significantly greater, with greater individual difference, than in healthy volunteers. Among patients with DLSDs, women had significantly more motion than men did during trunk extension. SI joint motion was significantly negatively correlated with the cross-sectional area of the trunk muscles during both flexion and extension of the trunk. CONCLUSIONS The authors elucidated the mobility and kinematic characteristics of the SI joint in patients with DLSDs compared with healthy volunteers for the first time. This information is useful for spine surgeons because of the recent increase in spinopelvic fusion for the treatment of DLSDs. PMID:25978076

    One of the most common indications for performing magnetic resonance (MR) imaging of the lumbar spine is the symptom complex thought to originate as a result of degenerative disk disease. MR imaging, which has emerged as perhaps the modality of choice for imaging degenerative disk disease, can readily demonstrate disk pathology, degenerative endplate changes, facet and ligamentous hypertrophic changes, and the sequelae of instability. Its role in terms of predicting natural history of low back pain, identifying causality, or offering prognostic information is unclear. As available modalities for imaging the spine have progressed from radiography, myelography, and computed tomography to MR imaging, there have also been advances in spine surgery for degenerative disk disease. These advances are described in a temporal context for historical purposes with a focus on MR imaging's history and current state. (orig.)

  19. Immunocytochemical demonstration of lymphocyte subsets and MHC class II antigen expression in synovial membranes from dogs with rheumatoid arthritis and degenerative joint disease.

    Hewicker-Trautwein, M; Carter, S D; Bennett, D; Kelly, D F

    1999-03-01

    The study describes the distribution of canine leucocyte antigens in synovial membrane biopsies from six dogs with canine rheumatoid arthritis (CRA) and from eight dogs with osteoarthritis (OA) secondary to spontaneous rupture of the cranial cruciate ligament (CCL) (n = 5) or patellar luxation (n = 3). Synovial membranes from five dogs without evidence of joint lesions were used as control tissues. In the subsynovium of dogs with normal joints CD5+, CD4+, CD8+ and alpha beta TCR+ lymphocytes were present only in low numbers. With monoclonal antibody (mAb) to MHC class II antigen, either none or up to 20-30% of synovial lining cells were immunoreactive. Furthermore, scattered MHCII+ stromal cells were seen in the deeper subsynovial layer. In synovial membrane biopsies from dogs with CRA numerous diffusely and perivascularly distributed CD5+ lymphocytes were found in the subsynovium. CD4+ cells outnumbered CD8+ cells and were more numerous in the perivascular areas. In all the CRA cases examined, there were markedly higher numbers of alpha beta TCR+ cells compared with gamma delta TCR+ cells. With mAb to CD21, low numbers of immunoreactive lymphocytes were demonstrated. In all the CRA cases, a marked increase of MHC class II antigen expression was noted. In the majority of samples, 50% or more than 90% of the synovial lining cells were strongly MHC class II+. Throughout the subsynovial layer there were numerous MHC class II+ cells and included those with dendritic morphology and inflammatory mononuclear cells. Furthermore, marked perivascular immunoreactivity for MHC class II antigen was found. In biopsies from dogs with OA, there were markedly lower numbers of subsynovial CD5+, CD4+ and CD8+ lymphocytes. T-cells were mainly diffusely distributed. In three of the eight OA dogs examined, there was an increased percentage of synovial lining cells expressing MHC class II. The majority of OA cases had subsynovial major histocompatibility complex (MHC) class II+ cells with a dendritic morphology. PMID:10206202

    2000-01-01

    Although a variety of surgical techniques are available for the surgical treatment of early degenerative disease of the ankle, arthrodesis remains the preferred treatment for severe cases. We studied 126 ankles with an average follow up of 39 months of whom 25 with early disease underwent debridement and cheilectomy, 18 with intermediate disease underwent lower tibial osteotomy and 83 with severe disease underwent either arthrodesis (78) or total ankle replacement (5). In 96% of cases there w...

  2. MRI in degenerative diseases of the cervical spine

    MRI has grown increasingly important in recent years in diagnosis of degenerative diseases of the cervical spine, due to improvements of method that have made it a valuable diagnostic tool. The following contribution gives a brief introduction to the pathophysiology of degenerative changes in the cervical vertebral column and to the indications for MRI, describing within the framework of imaging the present state of MR examination technique. The ranking of the various gradient echo sequences, of the 3D methods and of the administration of contrast media in cervical myelopathy and radiaculopathy is discussed. (orig.)

  3. MR imaging of the spine: trauma and degenerative disease

    The purpose of this paper is to discuss the capabilities and drawbacks of MR imaging in patients with trauma to the spine and degenerative spinal conditions. In spinal trauma MR imaging is secondary to plain X-ray films and CT because of the greater availability and ease of performance of these techniques and their superior capability for detecting vertebral fractures. Magnetic resonance imaging is useful for detecting ligamentous ruptures and intraspinal mass lesions such as hematoma, and for assessing the state of the spinal cord and prognosis of a cord injury. In degenerative spinal disease the necessity is emphasized of critically evaluating the clinical relevance of any abnormal feature detected, as findings of degenerative pathology are common in individuals without symptoms. Magnetic resonance myelography permits rapid and accurate assessment of the state of the lumbar nerve roots (compressed or not). In the cervical region the quality of the myelographic picture is often degraded in patients with a narrow spinal canal. (orig.)

  5. Radiotherapy of degenerative joint disorders. Indication, technique and clinical results

    From 1984 to 1994, 85 patients with painful osteoarthritis were treated. The mean follow-up was 4 (1 to 10) years. Seventy-three patients (103 joints) were available for long-term analysis: 17 patients (27 joints) with omarthrosis, 19 (20 joints) with rhizarthrosis, 31 (49 joints) with osteoarthritis of the knee and 6 patients (7 joints) with osteoarthritis of the hip. All patients were intensively pretreated over long time. Mean symptom duration prior to radiotherapy was 4 (1 to 10) years. Orthovoltage or linac photons were applied using some technical modifications depending upon the joint. Two radiotherapy series (6 x 1 Gy, total dose: 12 Gy, 3 weekly fractions) were prescribed. The interval between the 2 series was 6 weeks. The subjective pain profil was assessed prior to and 6 months after radiotherapy and at last follow-up. Forty-six (63%) patients (64 joints) achieved a reduction of pain symptoms; 16 of those had a 'major pain relief' and 14 'complete pain relief'. Large joints - knee and hip - responded better (64% each) than the rhizarthrosis (53%). All pain categories and grades and their combined pain score were significantly reduced. The pain reduction was mostly pronounced for the symptom 'pain at rest'. The orthopedic score correlated well with the subjective response of the patients. The thumb score improved in 11 (57%) joints, the shoulder score of Constant and Murley in 16 (59%), the Japonese knee score of Sasaki et al. in 33 (67%), the hip score of Harris in 5 (71%) joints. Only 9 of 19 patients which were treated to avoid surgery, had to be operated, and 3 of those received a total arthroplasty of the hip or knee. In multivariate analysis for the endpoint 'complete' or 'major pain relief' only the criterion 'symptom duration ?2 years prior to radiotherapy' was an independent negative prognostic parameter.

    Major manifestations of vertebral degenerative joint disease were observed on a Pre-Columbian Muisca series from the Soacha Cemetery (11th to 13th centuries) Colombia, South America. In total, 1,646 vertebrae of 83 individuals were examined. Osteophytes, vertebral body joint surface contour change ("lipping"), and vertebral body pitting were evaluated for each vertebral body. For apophyseal joints, joint surface contour change, pitting, and eburnation were recorded. Two methods of frequency calculation and five for vertebral degenerative disease diagnosis were applied and compared, allowing discussion of methodological considerations. Our study showed that 83% of individuals and 32% of vertebrae were classified as positive when diagnosed by the presence of at least one of the following manifestations: osteophytes, vertebral body joint surface contour change ("lipping"), apophyseal joint surface contour change, or eburnation (method called "Pitting excluded"). No significant differences were found between the sexes. In the youngest cohort (15-30 years), 65% of individuals and 10% of vertebrae exhibit at least one of the previously mentioned manifestations. High prevalences suggest a high level of physical activity beginning in childhood which may have accelerated the aging process in this Pre-Columbian population. Historical data are compatible with this hypothesis. PMID:18186506

    Full Text Available Thanks to the development of several new researches, the lifetime presented a significant increase, even so, we still have many obstacles to overcome − among them, manage and get responses regarding neurodegenerative diseases. Where we are in the understanding of neuroprotection? Do we really have protective therapies for diseases considered degeneratives such as amyotrophic lateral sclerosis and its variants, Parkinson’s disease, Alzheimer’s disease and many others? Neuroprotection is defined by many researches as interactions and interventions that can slow down or even inhibit the progression of neuronal degeneration process. We make some considerations on this neuroprotective effect.

    Vitiligo is characterized by the progressive disappearance of pigment cells from skin and hair follicle. Several in vitro and in vivo studies show evidence of an altered redox status, suggesting that loss of cellular redox equilibrium might be the pathogenic mechanism in vitiligo. However, despite the numerous data supporting a pathogenic role of oxidative stress, there is still no consensus explanation underlying the oxidative stress-driven disappear of melanocytes from the epidermis. In this study, in vitro characterization of melanocytes cultures from non-lesional vitiligo skin revealed at the cellular level aberrant function of signal transduction pathways common with neurodegenerative diseases including modification of lipid metabolism, hyperactivation of mitogen-activated protein kinase (MAPK) and cAMP response element-binding protein (CREB), constitutive p53-dependent stress signal transduction cascades, and enhanced sensibility to pro-apoptotic stimuli. Notably, these long-term effects of subcytotoxic oxidative stress are also biomarkers of pre-senescent cellular phenotype. Consistent with this, vitiligo cells showed a significant increase in p16 that did not correlate with the chronological age of the donor. Moreover, vitiligo melanocytes produced many biologically active proteins among the senescence-associated secretory phenotype (SAPS), such as interleukin-6 (IL-6), matrix metallo proteinase-3 (MMP3), cyclooxygenase-2 (Cox-2), insulin-like growth factor-binding protein-3 and 7 (IGFBP3, IGFBP7). Together, these data argue for a complicated pathophysiologic puzzle underlying melanocytes degeneration resembling, from the biological point of view, neurodegenerative diseases. Our results suggest new possible targets for intervention that in combination with current therapies could correct melanocytes intrinsic defects. PMID:23555779

  10. Computed tomographic evaluation of degenerative diseases of the lumbar spine

    Computed tomography (CT) of the lumbar spine is a new modality of far-reaching significance. Experience with this new technique has been extremely limited, less than 3 years at most institutions. There are few hard data, and few adequate clinical studies have been performed. Accordingly, the purpose of this article is to provide an understanding of the pathogenesis as well as the CT findings of the degenerative diseases affecting the spinal canal

    Idiopathic Parkinson's disease (PD) and Alzheimer's disease (AD) are the main neuro-degenerative diseases (NDDs) seen clinically. They share some common clinical symptoms and neuro-pathological findings. The increase of life expectancy in the developed countries will inevitably contribute to enhance the prevalence of these diseases. Behavioral disorders, common in NDDs, will produce major care management challenges. Idiopathic Parkinson's disease corresponds to a histopathological diagnosis, based on the observation of a de-pigmentation and a neuronal loss in the substantia nigra, as well as on the presence of intra-neuronal inclusion bodies. AD is insidious with slowly progressive dementia in which the decline in memory constitutes the main complaint. The diagnosis of definite AD requires the presence of clinical criteria as well as the histopathological confirmation of brain lesions. The two main lesions are the presence of senile plaques and neuro-fibrillary tangles. Positron emission tomography (PET) explores cerebral metabolism and neurotransmitter kinetics in NDDs using principally [{sup 18}F]-deoxyglucose and [{sup 18}F]-dopa. Nigrostriatal dopaminergic function is altered in PD, as evidenced by the low uptake of [{sup 18}F]-dopa in the posterior putamen as compared to anterior putamen and caudate nucleus. In contrast, [{sup 18}F]-dopa uptake is equally depressed in all striatal structures in progressive supra-nuclear palsy. Regional glucose metabolism at rest is preserved in elderly once cerebral atrophy is taken into account. On the contrary, glucose metabolism is globally reduced in AD, with marked decrease in the parietal and temporal regions. PET has proved to be useful to study in vivo neurochemical processes in patients suffering from NDDs. The potential of this approach is still largely unexploited, and depends on new ligand production to establish early diagnosis and treatment follow-up. (author)

  13. Degenerative diseases of the nervous system in atomic bomb survivors

    Degenerative diseases (DD) of the nervous system were observed in 169 of 23,418 A-bomb survivors enrolled in a cohort adult health survey. Senile dementia and parkinsonism accounted for 76 % of the DD. The incidence of DD tended to be higher with increasing exposure doses for women. This was significant for younger women at the time of bombing. No dose-dependence was seen for occurrence of DD in men. There was no significant difference in the incidence of DD between Hiroshima's and Nagasaki's survivors. (Namekawa, K.)

  14. Nuclear microscopy in medical research. Investigations into degenerative diseases

    The high energy (1-4MeV) focused ion beam (nuclear microbeam) has found uses in many scientific disciplines through a wide variety of ion beam based techniques. Of the many techniques available, the powerful combination of Particle Induced X-Ray Emission (PIXE), Rutherford Backscattering Spectrometry (RBS), and Scanning Transmission Ion Microscopy (STIM) is proving to be extremely useful, particularly in the characterisation and elemental analysis of thin specimens. In this paper we briefly review these ion beam techniques, as well as the hardware required for their application. Finally, we describe the application of the PIXE, RBS and STIM techniques in conjunction with a scanning focused 2MeV proton microbeam (nuclear microscopy). The examples chosen to illustrate the potential of nuclear microscopy are recent investigations into the degenerative diseases atherosclerosis (coronary heart disease), Parkinson's disease and Alzheimer's disease.

  16. MRI of degenerative lumbar spine disease: comparison of non-accelerated and parallel imaging

    Parallel imaging techniques such as GRAPPA have been introduced to optimize image quality and acquisition time. For spinal imaging in a clinical setting no data exist on the equivalency of conventional and parallel imaging techniques. The purpose of this study was to determine whether T1- and T2-weighted GRAPPA sequences are equivalent to conventional sequences for the evaluation of degenerative lumbar spine disease in terms of image quality and artefacts. In patients with clinically suspected degenerative lumbar spine disease two neuroradiologists independently compared sagittal GRAPPA (acceleration factor 2, time reduction approximately 50%) and non-GRAPPA images (25 patients) and transverse GRAPPA (acceleration factor 2, time reduction approximately 50%) and non-GRAPPA images (23 lumbar segments in six patients). Comparative analyses included the minimal diameter of the spinal canal, disc abnormalities, foraminal stenosis, facet joint degeneration, lateral recess, nerve root compression and osteochondrotic vertebral and endplate changes. Image inhomogeneity was evaluated by comparing the nonuniformity in the two techniques. Image quality was assessed by grading the delineation of pathoanatomical structures. Motion and aliasing artefacts were classified from grade 1 (severe) to grade 5 (absent). There was no significant difference between GRAPPA and non-accelerated MRI in the evaluation of degenerative lumbar spine disease (P > 0.05), and there was no difference in the delineation of pathoanatomical structures. For inhomogeneity there was a trend in favour of the conventional sequences. No significant artefacts were observed with either technique. The GRAPPA technique can be used effectively to reduce scanning time in patients with degenerative lumbar spine disease while preserving image quality. (orig.)

  17. Imaging of demyelinating and degenerative diseases of the brain

    The emergence of cross-sectional brain imaging in the past decade has greatly expanded the role of imaging as a primary diagnostic modality for demyelinating and degenerative brain disorders. To remain an effective neurologic consultant, the radiologist must better understand the neuropathology and functional significance of these disorders. MR imaging has become the dominant imaging modality for multiple sclerosis and all demyelinating and dysmyelinating disorders. Detection is most sensitive with intermediate and T2-weighted spin-echo pulse sequences. Although increased signal intensity in the white matter is a sensitive but nonspecific finding, a knowledge of the patient's history and disease pathoanatomy greatly improves diagnostic specificity. Since an increasing proportion of the population is over 65 years of age, the distinction of normal versus pathologic aging becomes critical. The role of imaging in dementing illness is to distinguish primary degenerative dementia from normal aging changes, vascular medullary artery distribution disease, microangiopathic leukoencephalopathy, communicating hydrocephalus, and mass lesions. The role of MR imaging, including brain iron mapping, is analyzed in bradykinetic, choreiform, and dystonic disorders. The complications of chronic ethanol abuse, including vermian atrophy, central pontine myelinolysis, and Wernicke encephalopathy, are also reviewed

  18. Looking ahead: what long-term outcomes can we expect from spinal devices for degenerative disc disease.

    Errico, Thomas J

    2008-01-01

    Degenerative disc disease is one of the leading causes of pain and disability. Various surgical treatments are available, but the literature does not provide a comparative overview of their long-term outcomes. This article synthesizes the available long-term evidence on the treatment of degenerative disc disease. Fusion for degenerative disc disease has recently shown good long-term clinical outcomes, yet several studies strongly suggest that it may accelerate the degenerative process at adjacent levels. Arthroplasty shows at least equivalent long-term outcomes and is not expected to accelerate adjacent degeneration, but speculative concern remains about its safety, especially in regard to wear debris and facet joint arthrosis. Many other treatment devices are in various stages of development, but long-term studies are not yet available for most of them. When making treatment decisions, physicians and patients must consider the long-term outcomes, because the devices remain implanted indefinitely, and back pain could recur at any time if the degeneration progresses or the device fails. Before making a treatment decision, surgeons and patients should thoroughly discuss the long-term clinical prognosis, the safety of various procedures, the degrees of certainty in our currently available medical knowledge, and the patient's preferences. No one solution will be right for every patient, but we are entering a golden era of choices, where most patients with degenerative disc disease should be able to find a treatment that substantially improves their condition.

  19. Bone and joint disease

    Plain radiography is an important tool in the diagnosis and evaluation of many types of arthritis. Important factors to consider when evaluating radiographs of arthritis patients are the age of the patient, the presence of known preexisting diseases, and the distribution of abnormalities, as well as the particular radiographic appearance of the patients' abnormalities. The most common variety of arthritis is degenerative osteoarthritis, while the most common inflammatory arthropathy is rheumatoid arthritis. Mastery of the radiographic appearance and distribution of these two disorders provides a firm bases for evaluating any arthropathy

  20. Imaging techniques for diagnosis after surgery for degenerative disc disease

    The magnetic resonance imaging findings recorded in patients after surgery for degenerative disc disease in the lumbar and cervical spine are discussed in comparison with conventional radiographs and computed tomography findings. In the lumbar spine normal postoperative findings in the immediate postoperative period can be demonstrated by MR imaging. Contrast-enhanced MR imaging can differentiate disc herniation from postoperative scar formation with a greater degree of confidence than other imaging modalities. MR imaging improves differentiation between other causes of failed back syndrome such as postoperative hematoma and infection, lateral spinal stenosis and arachnoiditis. In the cervical spine types of operative approaches, the appearance of bony stenosis and disc herniations by MR imaging are discussed. Computer tomography still has a role in the assessment of osseous complications such as central or foraminal stenosis. (orig.)

  1. Magnetic resonance imaging of canine degenerative lumbar spine diseases

    Degenerative lumbar spine diseases, i.e., sacrolumbar stenosis, intervertebral disk degeneration and protrusion and spondylosis deformans of the canine lumbar spine were studied in eleven canine patients and three healthy controls using radiography and 0.02 T and 0.04 T low field magnetic resonance imaging. The T1 and T2 weighted images were obtained in sagittal and transverse planes. The loss of hydration of nucleus pulposus, taken as a sign of degeneration in the intervertebral disks, could be evaluated in both T1 and T2 weighted images. As a noninvasive method magnetic resonance imaging gave more exact information about the condition of intervertebral disks than did radiography. Sacrolumbar stenosis and compression of the spinal cord or cauda equina and surrounding tissue could be evaluated without contrast medium

  2. Cell-Based Therapy for Degenerative Retinal Disease.

    Zarbin, Marco

    2016-02-01

    Stem cell-derived retinal pigment epithelium (RPE) and photoreceptors (PRs) have restored vision in preclinical models of human retinal degenerative disease. This review discusses characteristics of stem cell therapy in the eye and the challenges to clinical implementation that are being confronted today. Based on encouraging results from Phase I/II trials, the first Phase II clinical trials of stem cell-derived RPE transplantation are underway. PR transplant experiments have demonstrated restoration of visual function in preclinical models of retinitis pigmentosa and macular degeneration, but also indicate that no single approach is likely to succeed in overcoming PR loss in all cases. A greater understanding of the mechanisms controlling synapse formation as well as the immunoreactivity of transplanted retinal cells is urgently needed. PMID:26791247

  3. Health assessment of environmental pollutants: proliferative and degenerative diseases

    In order to achieve a balanced approach to risk assessment between carcinogenic and non-carcinogenic health effects one must examine the risk of disease or death in the general population exposed to a particular air pollutant that can be related quantitatively to intensity and duration of exposures (National Academy of Sciences, 1983). Such risk assessment should be based upon careful evaluation of scientific findings of dose-response relationships in the chronically exposed population. Quantitative assessment of environmentally produced disease in man has proven to be complex and demanding. A variety of factors play important roles in this task. As an example, there are induction-latency periods for chronic diseases, including cancer, which may range from five to twenty-five years. The diseases themselves, whether proliferative or degenerative, may follow several stages of progression. There is only sparse epidemiological data on serious health effects that may be due to environmental as compared to occupational exposures. Exposures to chemical or radiological air contaminants do not occur singly but to a multiplicity of agents, and disease processes are frequently markedly affected by the interaction of a variety of factors, particularly that of cigarette smoking. There is growing recognition of potentially sensitive subpopulations, including the elderly and the very young, but adequate techniques for assessing the magnitude of increased risks to these groups have not yet been developed

  4. Micro PIXE investigations. Time sequencing studies in degenerative diseases

    The simultaneously applied techniques of Particle Induced X-ray Emission (PIXE), Rutherford Backscattering Spectrometry (RBS) and Scanning Transmission Ion Microscopy (STIM), have been successful in mapping and quantifying trace elements during the progression of several human diseases, in particular those degenerative diseases which have a corresponding animal model. In atherosclerosis, iron has been shown to be present in increased concentrations at the early stage of lesion formation, and when the animal model has been kept anaemic, the artery wall shows a reduced uptake of iron and a delay in lesion formation compared with controls. In Parkinson's disease, there is also an increased concentration of iron in the substantia nigra region of the brain. Although the increase in bulk iron appears to lag behind the dopaminergic cell death, we have detected an increase in localized deposits of iron at the onset of cell death. These two results infer that iron may play a role in both diseases, perhaps through the mediation of free radicals. The induction of epilepsy through the injection of kainic acid has shown that the cell death is accompanied by an increase in calcium levels as early as one day after injection. The increase in calcium is consistent with activation of phospholipase A2 and free radical damage. (author)

    2002-03-01

    A degenerative skeletal muscle disease with vascular, neurologic, and renal lesions and a probable familial distribution was identified in 4-20-month-old purebred Gelbvieh cattle. Thirteen affected animals were confirmed from 6 separate beef herds, with a mortality rate of 100%. Clinical signs in affected animals consisted of ataxia, weakness, and terminal recumbency. Gross and histologic muscle lesions were indicative of nutritional myopathy of ruminants, with a lack of myocardial lesions in most cases and only rare myocardial changes in a few animals. Acute to chronic lesions in most large skeletal muscle groups consisted of degeneration, necrosis, regeneration, fibrosis, and atrophy. Fibrinoid necrosis of arterioles was a common feature in multiple tissues. Lesions in the spinal cord white matter and peripheral nerves consisted of degeneration of the dorsal columns and axons, respectively. Changes in the kidneys consisted of chronic interstitial nephritis with fibrosis, hyaline droplet change and tubular epithelial vacuolar change and were most severe in the older calves. Intracytoplasmic myoglobin and iron were demonstrated within the hyaline droplets in degenerate renal cortical tubular epithelial cells. Vitamin E levels were deficient in most (6/7) of the animals tested. Investigation of the pedigree of affected animals revealed a common ancestry for all but 1 of the animals whose parentage could be traced. This investigation suggests that a hereditary metabolic defect, possibly involving antioxidant metabolism, could be responsible for this condition. Renal disease, possibly secondary to myoglobinuria, may be unique to this bovine condition. PMID:11939335

    Degenerative-inflammatory lumbar spinal pathology is one of the most common reasons why individuals seek medical care, and low back pain is the main symptom among those most commonly associated with this pathologic condition. Pain is commonly attributed to degenerative disc disease, particularly herniated discs, but many different spinal and perispinal structures may undergo degenerative-inflammatory phenomena and produce pain: discs, bone, facet joints, ligaments and muscles. In particular, in patients with non-radicular low back pain, this syndrome may arise from changes of the posterior elements/perispinal tissues of the lumbar spine (i.e., the ''posterior vertebral compartment''). They include: facet joint pathology (e.g., osteoarthritis, joint effusion, synovitis and synovial cysts), spondylolysis, spinal/perispinal ligamentous degenerative-inflammatory changes and perispinal muscular changes. It is well known that magnetic resonance is the most sensitive imaging method for the evaluation of spinal degenerative pathology, even in the initial stages of the disease. T2-weighted sequences with fat saturation, and when indicated the use of contrast-enhanced T1-weighted images with fat saturation, permit the visualization of degenerative-inflammatory changes of the posterior elements of the lumbar spine that in most cases would have been overlooked with conventional non-fat suppressed imaging.

  7. Vertebral degenerative disc disease severity evaluation using random forest classification

    Munoz, Hector E.; Yao, Jianhua; Burns, Joseph E.; Pham, Yasuyuki; Stieger, James; Summers, Ronald M.

    2014-03-01

    Degenerative disc disease (DDD) develops in the spine as vertebral discs degenerate and osseous excrescences or outgrowths naturally form to restabilize unstable segments of the spine. These osseous excrescences, or osteophytes, may progress or stabilize in size as the spine reaches a new equilibrium point. We have previously created a CAD system that detects DDD. This paper presents a new system to determine the severity of DDD of individual vertebral levels. This will be useful to monitor the progress of developing DDD, as rapid growth may indicate that there is a greater stabilization problem that should be addressed. The existing DDD CAD system extracts the spine from CT images and segments the cortical shell of individual levels with a dual-surface model. The cortical shell is unwrapped, and is analyzed to detect the hyperdense regions of DDD. Three radiologists scored the severity of DDD of each disc space of 46 CT scans. Radiologists' scores and features generated from CAD detections were used to train a random forest classifier. The classifier then assessed the severity of DDD at each vertebral disc level. The agreement between the computer severity score and the average radiologist's score had a quadratic weighted Cohen's kappa of 0.64.

  8. Chondroprotectant therapy in rats with degenerative joint disease experimentally transected cranial cruciateReprodução experimental da doença articular degenerativa, pelo método cirúrgico associado à terapia condroprotetora, em ratos

    Marcos Marini Melo

    2013-06-01

    Full Text Available Osteoarthritis (OA is the most common joint disease in both humans and animals, and it results in movement restriction and pain at the affected area. This disorder affects more than 25% of people over 60 years of age, and it is considered universal for 70-year-old people. OA is estimated to affect over 20% of the canine population from the United States of America. The present study aimed to evaluate the treatment of rats that were surgically induced to OA using two different drug therapies, one with pentosan polysulfate, one with betamethasone, and one with chondroitin sulfate/ glucosamine. In order to produce joint disease, the cranial cruciate ligament was surgically transected. Animals were kept and treated for eight days after surgery and were assessed via both radiographies and tomographies taken before surgery and eight weeks later. All animals were euthanized having both macroscopic and microscopic analysis performed to evaluate the disorder progression and therapeutic action. Macroscopic analysis showed lesion in the knees subjected to OA induction. The untreated animals presented major lesions whereas the treated ones presented mild to moderate lesions. In conclusion, pentosan polysulfate is recommendable for the treatment of iatrogenic joint lesions in rats since the other treatments showed no significant difference. A osteoartrite (OA é a doença articular mais comum em humanos e animais, o que ocasiona restrição de movimentos e dor, na região acometida. Tal enfermidade afeta mais de 25% dos humanos acima de 60 anos e, aos 70 anos, ela é considerada universal. Estima-se que nos Estados Unidos da América, 20% ou mais da população canina é acometida pela OA. O presente estudo tem como finalidade avaliar a terapia medicamentosa (polisulfato de pentosano, betametasona e sulfato de condroitina/glucosamina, em um modelo experimental de OA cirurgicamente induzido, em ratos. A doença articular foi promovida pela transecção cirúrgica do ligamento cruzado cranial, sendo que, após o procedimento cirúrgico, os animais foram mantidos e tratados por oito semanas. Foi realizada avaliação radiográfica e tomográfica antes e oito semanas após a indução da osteoartrite. Todos os animais foram submetidos à eutanásia para análise macroscópica e microscópica, que foram realizadas para avaliar a progressão da enfermidade e a ação terapêutica. Na análise macroscópica foi observadas lesões nos joelhos submetidos à indução OA. Os animais não tratados apresentaram lesões graves enquanto que, os animais tratados apresentaram lesões leves a moderadas. Concluiu-se que o polissulfato de pentosano é eficiente no tratamento de lesões articulares iatrogênicas de ratos, uma vez que outros tratamentos não mostraram qualquer diferença significativa.

    2014-01-01

    The cerebellum is essentially involved in movement control and plays a critical role in motor learning. It has remained controversial whether patients with degenerative cerebellar disease benefit from high-intensity coordinative training. Moreover, it remains unclear by which training methods and mechanisms these patients might improve their motor performance. Here, we review evidence from different high-intensity training studies in patients with degenerative spinocerebellar disease. These s...

    Abushkin, Ivan A.; Privalov, Valery A.; Lappa, Alexander V.; Noskov, Nikolay V.; Neizvestnykh, Elena A.; Kotlyarov, Alexander N.; Shekunova, Yulia G.

    2014-03-01

    Two low invasive laser technologies for treatment of degenerative-dystrophic bone diseases in children are presented. The first is the transcutaneous laser osteoperforation developed by us and initially applied for treatment of different inflammatory and traumatic diseases (osteomyelitides, osteal and osteoarticular panaritiums, delayed unions, false joints, and others). Now the technology was applied to treatment of aseptic osteonecrosis of different localizations in 134 children aged from 1 to 16 years, including 56 cases with necrosis of femoral head (Legg-Calve-Perthes disease), 42 with necrosis of 2nd metatarsal bone head (Kohler II disease), and 36 with necrosis of tibial tuberosity (Osgood-Schlatter disease). The second technology is the laser intracystic thermotherapy for treatment of bone cysts. The method was applied to 108 children aged from 3 to 16 years with aneurismal and solitary cysts of different localizations. In both technologies a 970 nm diode laser was used. The suggested technologies increase the efficiency of treatment, reduce its duration, can be performed on outpatient basis, which resulted in great economical effect.

    2009-12-01

    Retinal degenerative diseases, including age-related macular degeneration and retinitis pigmentosa, are the prodominant causes of human blindness in the world; however, these diseases are difficult to treat. Currently, knowledge on the mechanisms of these diseases is still very limited and no radical drugs are available. Induced pluripotent stem (iPS) cells are an innovative technology that turns somatic cells into embryonic stem (ES)-like cells with pluripotent potential via the exogenous expression of several key genes. It can be used as an unlimited source for cell differentiation or tissue engineering, either of which is a promising therapy for human degenerative diseases. Induced pluripotent cells are both an unlimited source for retinal regeneration and an expectant tool for pharmaprojects and developmental or disease modelling. In this review, we try to summarize the advancement of iPS-based technologies and the potential utility for retinal degenerative diseases. We also discuss the challenges of using this technology in the retinology field.

  14. Anatomical basics, variations, and degenerative changes of the shoulder joint and shoulder girdle

    This paper summarizes the anatomical basics of the shoulder, their variations, and precise definitions, including differential diagnoses. It also describes the characteristic degenerative changes caused by aging. A typical variation (7-15%) is the os acromiale, which forms the triangular epiphysis of the scapular spine. This abnormality must be differentiated from a fracture of the acromion or a pseudarthrosis. Because ossification of the acromion is complete after age 25, the os acromiale should be diagnosed only after this age. The shape of the acromion is a further important feature. In a recent anatomical study, the following frequencies of the Bigliani-types of the acromial shape were anatomically determined - type 1 (flat), 10.2% and type 2 (curved), 89.8%. Type 3 (hooked) was not observed, which indicates that this type is probably a misinterpretation of the so-called acromial spur. Minor dehiscences and perforations in the infraspinate or supraspinate fossa should not be confused with malignant osteolyses. The scapula has three ligaments of its own, (1) the coracoacromial ligament and its osseous fixations form an osteofibrous arch above the shoulder joint, which plays a part in impingement syndrome; (2) the superior transverse scapular ligament or its ossified correlate arches the scapular incisure and can cause a typical compression syndrome of the suprascapular nerve; (3) the inferior transverse scapular ligament is of no great clinical importance. Two intraarticular structures (glenoid labrum and tendon of the long bicipital head) must be mentioned. The glenoid labrum consists of dense connective tissue and surrounds the margin of the glenoid cavity. Two areas exhibit specialized conditions, cranial at the supraglenoid tubercle an intimate relationship exists to the tendon of the long bicipital head and in about 55% of cases, the labrum is stretched over the glenoid rim at the ventral side. At the area of the biceps-tendon-labrum complex, so-called SLAP-lesions may occur and at the glenoid rim, where the labrum is often not fixed to the bony margin, avulsions of the labrum may occur. This well-established anatomical condition must not be mistaken for a manifest Bankart-lesion. The glenohumeral ligaments, which are located in the ventral articular capsule, have a stabilizing function for the ventral part of the glenoid labrum. The glenohumeral ligaments lift the articular lip where it crosses the glenoid notch. This 'labrum-lift effect' supports the stabilizing features of the articular lip and the glenohumeral ligaments. The rotator cuff is composed of the tendons of the teres minor, infraspinatus, supraspinatus, and subscapularis muscles. This cuff has a poorly vascularized area, due to mechanical conditions, about 1.5 cm from the major tubercle, which causes degenerative changes and eventually may lead to ruptures. Results of the impingement-syndrome and the osteoarthrotic changes of the shoulder and acromioclavicular joint are also presented and discussed. Finally, the coracoclavicular joint, which probably represents no congenital entity but appears due to a changed, lowered position of the shoulder girdle, is discussed. The paper also presents instructive figures of anatomical preparations that can be used to make more precise radiological and differential diagnoses. All preparations were done by the author and are part of a series of more than 300 preparations of the shoulder joint and girdle.

  16. Bowman lecture on the role of inflammation in degenerative disease of the eye

    Forrester, J V

    2013-01-01

    Inflammation, in the pathogenesis of many diseases previously thought to be strictly genetic, degenerative, metabolic, or endocrinologic in aetiology, has gradually entered the framework of a general mechanism of disease. This is exemplified by conditions such as Parkinson's disease, Alzheimer's disease, atherosclerosis, diabetes, and the more recently described Metabolic Syndrome. Chronic inflammatory processes have a significant, if not primary role, in ophthalmic diseases, particularly in ...

  17. Cerebral atrophic and degenerative changes following various cerebral diseases, (1)

    Patients having cerebral atrophic and degenerative changes following hypoglycemia, cerebral contusion, or cerebral hypoxia including cerebrovascular disorders were reported. Description was made as to cerebral changes visualized on CT images and clinical courses of a patient who revived 10 minutes after heart stoppage during neurosurgery, a newborn with asphyxia, a patient with hypoglycemia, a patient who suffered from asphyxia by an accident 10 years before, a patient with carbon monoxide poisoning at an acute stage, a patient who had carbon monoxide poisoning 10 years before, a patient with diffuse cerebral ischemic changes, a patient with cerebral edema around metastatic tumor, a patient with respiration brain, a patient with neurological sequelae after cerebral contusion, a patient who had an operation to excise right parietal lobe artery malformation, and a patient who was shooted by a machine gun and had a lead in the brain for 34 years.

  18. Single- or multiple-session viscosupplementation protocols for temporomandibular joint degenerative disorders: a randomized clinical trial.

    Guarda-Nardini, L; Rossi, A; Arboretti, R; Bonnini, S; Stellini, E; Manfredini, D

    2015-07-01

    The aim of the study was to compare the effectiveness of two single-session protocols, either adopting high- (protocol A) or medium-molecular weight hyaluronic acid (protocol B), with the reference five-session protocol of temporomandibular joint (TMJ) lavage plus viscosupplementation (protocol C) in the management of chronic TMJ degenerative disorders. A randomized clinical trial (RCT) with ten participants per treatment group was designed, with multiple observation points, ending at 6 months after treatment. Pain levels on a 10-point VAS scale were selected as the primary outcome variable to rate treatment effectiveness, along with a number of secondary outcome parameters. Findings showed that Group C patients had the highest decrease in pain levels. Nonparametric permutation analyses revealed that the global effect of treatment was significantly different between the three protocols (P = 0·024). Pairwise comparisons showed that the differences of treatment effect between the two single-session interventions were negligible (global P-value = 0·93). On the contrary, the five-session protocol was significantly superior to both single-session protocols (global P-values ranging from 0·003 to 0·012). In conclusion, in a population of age-, sex-, and psychosocial aspects-matched study groups, the standard of reference five-session protocol proved to be superior at 6 months as far as the decrease in pain levels was concerned, whilst there were no differences between the two single-session interventions. The absence of differences in treatment effect as for some other secondary clinical outcome variables may suggest that there is further space for future investigations attempting to reduce the number of multiple interventions for TMJ viscosupplementation.

Aps trs semanas de instabilidade articular, o LCCr foi substitudo pela fscia lata segundo a tcnica de Schwalder (1989 e os animais foram distribudos em trs grupos de cinco. Os animais do grupo I, controle, no receberam tratamento medicamentoso; os do grupo II, 24mg/animal de sulfato de condroitina, por via IM, de cinco em cinco dias, totalizando seis aplicaes; e os do grupo III foram tratados com hialuronato de sdio na dose de 20mg/animal, por via IV, de cinco em cinco dias num total de trs administraes. Ao final de 90 dias, os animais foram eutanasiados e procedeu-se colheita e ao processamento histolgico da membrana sinovial e da cartilagem articular para avaliaes morfolgica e morfomtrica. No grupo I foram observadas alteraes degenerativas de DAD mais acentuadas que nos demais grupos, como reduo do nmero de condrcitos, presena de pnus, fibrilaes, fissuras, eroses e irregularidades na superfcie articular. No grupo II observou-se elevao do nmero de condrcitos com aumento da atividade de sntese da matriz e reduo das leses na superfcie da cartilagem. No grupo III houve aumento do nmero de condrcitos que eram, muitas vezes, morfologicamente inviveis. Todos os grupos apresentaram proliferao da membrana sinovial e presena de infiltrado linfoplasmocitrio na subntima e na perivascular. Nos grupos I e III, a proliferao da membrana sinovial era exuberante com formao de pnus, presena de sinovicitos achatados ou ausncia de sinvia com tecido de granulao. Os resultados sugerem que o sulfato de condroitina estimulou a cartilagem articular, diminuindo ou retardando as alteraes da DAD e o hialuronato de sdio no interferiu no processo degenerativo da cartilagem articular. No foi constatada ao favorvel das drogas na membrana sinovial.Fifteen mongrel dogs, both genders, weighting from 18 to 25kg were used and Degenerative Joint Disease (DJD was induced through cranial cruciate ligament (CCrL artroscopical section. After three weeks, CCrL was reconstructed by Schawalder's (1989 technique. Then, dogs were distributed in three groups and the following protocols were used: group I, control, no other treatment but the CCrL reconstruction; group II received chondroitin sulfate 24mg per animal every five days, intramuscularly, in a total of six injections; and group III received sodium hyaluronate 20mg per animal every five days, intravenously, in a total of three injections. Clinical observation was done until 90 days after treatments. By that time, the articular cartilage and synovium were collected and their morphology was evaluated. In group I, the degenerative alterations of the DJD were the most intense. Thus, decrease of chondrocytes number, pannus, fibrillations, grooves, erosion, and irregular articular surface were observed on the cartilage. In group II, raise of chondrocytes number was observed, with increase of synthesis activity of matrix and decrease of lesions on the articular surface. There was an increase of chondrocytes in group III, but the cells were morphologically unviable. All the groups showed proliferation of the synovial membrane, with limpho-plasma cells infiltrated in subintim and perivascular. In groups I and III, the proliferation of synovium was abundant, with formation of pannus, flattened synoviocytes or synovium absent with granulation tissue. Those results suggest that the chondroitin sulfate stimulated the articular cartilage; decreasing or delaying the alterations of DJD, as well as, the sodium hyaluronate did not interfere on degenerative process in articular cartilage. No favorable action of these drugs in the synovial membrane was verified.

  20. Motor training in degenerative spinocerebellar disease: ataxia-specific improvements by intensive physiotherapy and exergames.

    Synofzik, Matthis; Ilg, Winfried

    2014-01-01

    The cerebellum is essentially involved in movement control and plays a critical role in motor learning. It has remained controversial whether patients with degenerative cerebellar disease benefit from high-intensity coordinative training. Moreover, it remains unclear by which training methods and mechanisms these patients might improve their motor performance. Here, we review evidence from different high-intensity training studies in patients with degenerative spinocerebellar disease. These studies demonstrate that high-intensity coordinative training might lead to a significant benefit in patients with degenerative ataxia. This training might be based either on physiotherapy or on whole-body controlled videogames ("exergames"). The benefit shown in these studies is equal to regaining one or more years of natural disease progression. In addition, first case studies indicate that even subjects with advanced neurodegeneration might benefit from such training programs. For both types of training, the observed clinical improvements are paralleled by recoveries in ataxia-specific dysfunctions (e.g., multijoint coordination and dynamic stability). Importantly, for both types of training, the retention of the effects seems to depend on the frequency and continuity of training. Based on these studies, we here present preliminary recommendations for clinical practice, and articulate open questions that might guide future studies on neurorehabilitation in degenerative spinocerebellar disease.

  1. No publication bias in industry funded clinical trials of degenerative diseases of the spine.

    Son, Colin; Tavakoli, Samon; Bartanusz, Viktor

    2016-03-01

    Industry sponsorship of clinical research of degenerative diseases of the spine has been associated with excessive positive published results as compared to research carried out without industry funding. We sought the rates of publication of clinical trials of degenerative diseases of the spine based on funding source as a possible explanation for this phenomenon. We reviewed all clinical trials registered at clinicaltrials.gov relating to degenerative diseases of the spine as categorized under six medical subject heading terms (spinal stenosis, spondylolisthesis, spondylolysis, spondylosis, failed back surgery syndrome, intervertebral disc degeneration) and with statuses of completed or terminated. These collected studies were categorized as having, or not having, industry funding. Published results for these studies were then sought within the clinicaltrials.gov database itself, PubMed and Google Scholar. One hundred sixty-one clinical trials met these criteria. One hundred nineteen of these trials had industry funding and 42 did not. Of those with industry funding, 45 (37.8%) had identifiable results. Of those without industry funding, 17 (40.5%) had identifiable results. There was no difference in the rates of publication of results from clinical trials of degenerative diseases of the spine no matter the funding source. PMID:26545332

    To determine the effect of degenerative disease of the lumbar spine on bone mineral density in the lumbar spine and femoral neck. We reviewed radiographs and dual energy x-ray absorptiometry scans of the lumbar spine and hip in 305 Caucasian women with suspected osteoporosis. One hundred and eight-six patient remained after excluding women less than 40 years of age (n=18) and those with hip osteoarthritis, scoliosis, lumbar spine fractures, lumbar spinal instrumentation, hip arthroplasty, metabolic bone disease other than osteoporosis, or medications known to influence bone metabolism (n=101). On the basis of lumbar spine radiographs, those with absent/mild degenerative disease were assigned to the control group and those with moderate/severe degenerative disease to the degenerative group. Spine radiographs were evaluated for degenerative disease by two radiologists working independently; discrepant evaluations were resolved by consensus. Lumbar spine and femoral neck bone mineral density was compared between the two groups. Forty-five (24%) of 186 women were assigned to the degenerative group and 141 (76%) to the control group. IN the degenerative group, mean bone mineral density measured 1.075g/cm? in the spine and 0.788g/cm{sup 2} in the femoral neck, while for controls the corresponding figures were 0.989g/cm{sup 2} and 0.765g/cm{sup 2}. Adjusted for age, weight and height by means of analysis of variance, degenerative disease of the lumbar spine was a significant predictor of increased bone mineral density in the spine (p=0.0001) and femoral neck (p=0.0287). Our results indicate a positive relationship between degenerative disease of the lumbar spine and bone mineral density in the lumbar spine and femoral neck, and suggest that degenerative disease in that region, which leads to an intrinsic increase in bone mineral density in the femoral neck, may be a good negative predictor of osteoporotic hip fractures.

Patients with degenerative sacroiliitis or sacroiliac joint disruption resistant to nonsurgical treatments may undergo open surgery with sacroiliac joint arthrodesis, although outcomes are mixed and risks are significant. Minimally invasive sacroiliac joint arthrodesis was developed to minimize the risk of iatrogenic injury and to improve patient outcomes compared with open surgery.Methods: Between April 2009 and January 2013, 5319 patients were treated with the iFuse SI Joint Fusion System for conditions including sacroiliac joint disruption and degenerative sacroiliitis. A database was prospectively developed to record all complaints reported to the manufacturer in patients treated with the iFuse device. Complaints were collected through spontaneous reporting mechanisms in support of ongoing mandatory postmarket surveillance efforts.Results: Complaints were reported in 204 (3.8% patients treated with the iFuse system. Pain was the most commonly reported clinical complaint (n = 119, 2.2%, with nerve impingement (n = 48, 0.9% and recurrent sacroiliac joint pain (n = 43, 0.8% most frequently cited. All other clinical complaints were rare (?0.2%. Ninety-six revision surgeries were performed in 94 (1.8% patients at a median follow-up of four (range 030 months.

  11. Gadolinium DTPA-enhanced MRI of degenerative cervical spine disease

    Thirty-two patients with 30 disc herniations and 5 bony stenoses were investigated together with 5 control subjects, using plain and contrast-enhanced Magnetic resonance imaging. Compared with the control group, additional non-enhancing epidural tissue was found in all patients. The enhancing epidural structures demonstrated characteristic changes. Compared with plain images, disease definition was improved in 7 of 35 cases after contrast administration. This was especially true for lateral and intraforaminal disc herniations, whereas no diagnostic benefit was seen in cases of posterior and posterolateral herniations or bony changes. (orig.)

  12. [Theoretic basis on the same therapeutic program for different degenerative brain diseases in terms of the Governor Vessel: Alzheimer's disease and Parkinson's disease].

    Wu, Junyan; Wang, Jie; Zhang, Junlong

    2015-05-01

    Through the consultation of TCM ancient classical theory, the relationship of kidney essence, marrow and brain is analyzed. It is discovered that the degenerative brain diseases, represented by Alzheimer's disease (AD) and Parkinson's disease (PD) share the same etiological basis as "kidney essence deficiency and brain marrow emptiness" and have the mutual pathological outcomes as yang qi declining. The Governor Vessel gathers yang qi of the whole body and maintains the normal functional activity of zangfu organs in the human body through the storage, regulation and invigoration of yang qi. It is viewed that the theory of the Governor Vessel is applied to treat the different degenerative brain diseases, which provides the theoretic support and practice guide for the thought of TCM as the same therapeutic program for the different diseases. As a result, the degenerative brain diseases can be retarded and the approach is provided to the effective prevention and treatment of degenerative diseases in central nerve system: PMID:26255528

  13. Neurochemical imaging of Alzheimer's disease and other degenerative dementias

    A wide variety of neurochemical and functional imaging approaches have been applied to the study of progressive dementias, particularly Alzheimer's disease (Ad) and related disorders. Despite considerable progress in the past decade, the cause((s) of most cases of Ad remain undetermined and preventive or protective therapies are lacking. Specifically-designed imaging procedures have permitted the testing of pathophysiological hypotheses of the etiology and progression of Ad, and have yielded important insights in several areas including the potential roles of cerebral cortical cholinergic lesions, cellular inflammation, and losses of cortical synapses. From the perspective of clinical diagnosis, PET glucose metabolism imaging with use of (18F)2-fluorodeoxyglucose (FDG) is the most sensitive and specific imaging modality yet identified. The overall performance of PET FDG is favorable for routine clinical evaluation of suspected Ad, and will likely gain increasing utilization in the near future. Assessments of glucose metabolism and other, specific aspects of neurochemistry in Ad will provide direct measures of therapeutic drug actions and may permit distinction of symptomatic versus disease-modifying therapies as they are developed and introduced in clinical trials

  14. Advances in Susceptibility Genetics of Intervertebral Degenerative Disc Disease

    Yin'gang Zhang, Zhengming Sun, Jiangtao Liu, Xiong Guo

    2008-01-01

    Full Text Available The traditional view that the etiology of lumbar disc herniation is primarily due to age, gender, occupation, smoking and exposure to vehicular vibration dominated much of the last century. Recent research indicates that heredity may be largely responsible for the degeneration as well as herniation of intervertebral discs. Since 1998, genetic influences have been confirmed by the identification of several genes forms associated with disc degeneration. These researches are paving the way for a better understanding of the biologic mechanisms. Now, many researchers unanimously agree that lumbar disc herniation appears to be similar to other complex diseases, whose etiology has both environmental and hereditary influence, each with a part of contribution and relative risk. Then addressing the etiological of lumbar disc herniation, it is important to integrate heredity with the environment factors. For the purpose of this review, we have limited our discussion to several susceptibility genes associated with disc degeneration.

    Neuroimaging offers a powerful means to assess the trajectory of brain degeneration in a variety of disorders, including Alzheimer's disease (AD). Here we describe how multi-modal imaging can be used to study the changing brain during the different stages of AD. We integrate findings from a range of studies using magnetic resonance imaging (MRI), positron emission tomography (PET), functional MRI (fMRI) and diffusion weighted imaging (DWI). Neuroimaging reveals how risk genes for degenerative disorders affect the brain, including several recently discovered genetic variants that may disrupt brain connectivity. We review some recent neuroimaging studies of genetic polymorphisms associated with increased risk for late-onset Alzheimer's disease (LOAD). Some genetic variants that increase risk for drug addiction may overlap with those associated with degenerative brain disorders. These common associations offer new insight into mechanisms underlying neurodegeneration and addictive behaviors, and may offer new leads for treating them before severe and irreversible neurological symptoms appear.

    Chan, E. S. L.; Fernandez, P.; Cronstein, B. N.

    2007-01-01

    Inflammatory joint diseases are a group of heterogeneous disorders with a variety of different etiologies and disease manifestations. However, there are features that are common to all of them: first, the recruitment of various inflammatory cell types that are attracted to involved tissues over the course of the disease process. Second, the treatments used in many of these diseases are commonly medications that suppress or alter immune function. The demonstration that adenosine has endogenous...

    Low back pain as a result of degenerative disc disease imparts a large socioeconomic impact on the health care system. Traditional concepts for treatment of lumbar disc degeneration have aimed at symptomatic relief by limiting motion in the lumbar spine, but novel treatment strategies involving stem cells, growth factors, and gene therapy have the theoretical potential to prevent, slow, or even reverse disc degeneration. Understanding the pathophysiological basis of disc degeneration is essen...

    2012-01-01

    To date, several studies were conducted to find which procedure is superior to the others for the treatment of cervical myelopathy. The goal of surgical treatment should be to decompress the nerves, restore the alignment of the vertebrae, and stabilize the spine. Consequently, the treatment of cervical degenerative disease can be divided into decompression of the nerves alone, fixation of the cervical spine alone, or a combination of both. Posterior approaches have historically been considere...

  3. Degenerative osteoarthritis of atlanto-odontoid joint: CT findings and clinical analysis

    Purpose: To analyze the CT appearances and clinical aspects of the degeneration at atlanto-odontoid(A-O) joint. Methods: Thin section axial CT scans, of AO joints were studied in 317 consecutive patients who underwent brain or cervical spine CT examinations. The images were viewed using double-blind method. Observation included: osteophytosis, changes of joint space and transverse ligament, and the clinical symptoms as well. Results: CT findings of AO joint degeneration included: formation of osteophyte, narrowing of joint space, transverse ligament calcification, and joint vacuum phenomenon. Among individuals above 40 years of age, the incidence of degeneration at AO joint went up gradually (P<0.01). Conclusion: Degeneration of AO joint was not uncommon among aged people, CT could better demonstrate the pathological changes

  4. Differentiation of malignant and degenerative benign bone disease using 99mTc-citrate scintigraphy

    Objective: To differentiate malignant and degenerative benign bone disease using 99mTc- citrate scintigraphy. Methods: Thirty-nine patients (92 lesions) with confirmed malignant bone disease or degenerative benign bone disease were studied, for which the results of 99mTe-methylene diphosphonate(99mTc- MDP) scintigraphy were positive. 99mTc-citrate scintigraphy was performed within a time interval of 2-7 days after 99mTc-MDP scintigraphy. Visual analysis and semiquantitative analysis were applied. Each lesion was scored as malignant or benign, which was independently verified, using conventional techniques (histopathology, X-ray, CT, MRI and clinical follow up). Results: In visual analysis of 99mTc-citrate imaging, most malignant lesions (35/48, 72.92%) clearly showed high radioactivity accumulation, while most benign lesions (39/44, 88.64%) had not obviously visible uptake of 99mTc-citrate. In semiquantitative analysis of 99mTc- citrate image, malignant lesions demonstrated a higher lesion-to-background radioisotope uptake ratio (RUR) than that of benign degenerative lesions (1.47 ± 0.42 vs. 1.09 ± 0.38, t=2.887, P99mTc-MDP in the two groups is of the same (1.96 ± 0.25 vs. 1.87 ± 0.21, t=1.178, P>0.20). Conclusion: 99mTc- citrate scintigraphy is a promising method to differentiate malignant from benign degenerative lesions seen as areas of increased activity on 99mTc-MDP bone scintigraphy.

  5. Degenerative disc disease in the lumbar spine: Another cause for focally reduced activity on marrow scintigraphy

    A patient is presented in whom a focal reduction in marrow activity in the lumbar spine on both leucocyte and nanocolloid marrow scintigraphy was subsequently shown to be due to fatty infiltration of marrow in association with disc degeneration. Degenerative disease in the lumbar spine has not been previously described as a cause of abnormal bone marrow distribution by such means and needs to be distinguished from a more serious pathology, such as malignant infiltration and vertebral infection, which it may mimic. In a retrospective review of 33 nanocolloid bone marrow and 117 leucocyte scintigrams, 8 showed a degree of reduced marrow activity in the lumbar spine consistent with that caused by degenerative changes.

  8. Evidence Report: Risk of Cardiovascular Disease and Other Degenerative Tissue Effects from Radiation Exposure

    Patel, Zarana; Huff, Janice; Saha, Janapriya; Wang, Minli; Blattnig, Steve; Wu, Honglu; Cucinotta, Francis

    2015-01-01

    Occupational radiation exposure from the space environment may result in non-cancer or non-CNS degenerative tissue diseases, such as cardiovascular disease, cataracts, and respiratory or digestive diseases. However, the magnitude of influence and mechanisms of action of radiation leading to these diseases are not well characterized. Radiation and synergistic effects of radiation cause DNA damage, persistent oxidative stress, chronic inflammation, and accelerated tissue aging and degeneration, which may lead to acute or chronic disease of susceptible organ tissues. In particular, cardiovascular pathologies such as atherosclerosis are of major concern following gamma-ray exposure. This provides evidence for possible degenerative tissue effects following exposures to ionizing radiation in the form of the GCR or SPEs expected during long-duration spaceflight. However, the existence of low dose thresholds and dose-rate and radiation quality effects, as well as mechanisms and major risk pathways, are not well-characterized. Degenerative disease risks are difficult to assess because multiple factors, including radiation, are believed to play a role in the etiology of the diseases. As additional evidence is pointing to lower, space-relevant thresholds for these degenerative effects, particularly for cardiovascular disease, additional research with cell and animal studies is required to quantify the magnitude of this risk, understand mechanisms, and determine if additional protection strategies are required.The NASA PEL (Permissive Exposure Limit)s for cataract and cardiovascular risks are based on existing human epidemiology data. Although animal and clinical astronaut data show a significant increase in cataracts following exposure and a reassessment of atomic bomb (A-bomb) data suggests an increase in cardiovascular disease from radiation exposure, additional research is required to fully understand and quantify these adverse outcomes at lower doses (less than 0.5 gray (SI unit for ionizing radiation dosage, i.e. one joule of radiation energy per one kilogram of matter)) to facilitate risk prediction. This risk has considerable uncertainty associated with it, and no acceptable model for projecting degenerative tissue risk is currently available. In particular, risk factors such as obesity, alcohol, and tobacco use can act as confounding factors that contribute to the large uncertainties. The PELs could be violated under certain scenarios, including following a large SPE (solar proton event) or long-term GCR (galactic cosmic ray) exposure. Specifically, for a Mars mission, the accumulated dose is sufficiently high that epidemiology data and preliminary risk estimates suggest a significant risk for cardiovascular disease. Ongoing research in this area is intended to provide the evidence base for accurate risk quantification to determine criticality for extended duration missions. Data specific to the space radiation environment must be compiled to quantify the magnitude of this risk to decrease the uncertainty in current PELs and to determine if additional protection strategies are required. New research results could lead to estimates of cumulative radiation risk from CNS and degenerative tissue diseases that, when combined with the cancer risk, may have major negative impacts on mission design, costs, schedule, and crew selection. The current report amends an earlier report (Human Research Program Requirements Document, HRP-47052, Rev. C, dated Jan 2009) in order to provide an update of evidence since 2009.

  9. Metabolic and degenerative diseases of the brain in children: Role of MR imaging

    Thirty-nine children with a variety of degenerative brain disorders including Leigh disease, Hallervorden-Spatz disease, leukodystrophies, and various metabolic conditions were examined with MR imaging. Imaging results were positive in more than 80%. The most common abnormalities included signal alterations of the basal ganglia and white matter, as well as local or generalized brain atrophy. The distribution of the findings showed certain patterns, allowing tentative classification among patients with nonspecific clinical or laboratory findings. Serial MR images, obtained in several patients, accurately reflected changes in clinical status. CT in general yielded less information about MR imaging

  10. MRI of degenerative bone marrow lesions in experimental osteoarthritis of canine knee joints

    Objective. The objective of this study was to determine the value of MRI in the detection of degenerative bone marrow abnormalities in an animal osteoarthritis model. Design. In 10 dogs with experimentally induced unilateral osteoarthritis of the knee, MRI was performed using two-dimensional spin-echo (2D-SE) and three-dimensional gradient-echo (3D-GE) imaging. Contrast enhanced T1-weighted 2D-SE sequences were also obtained after injection of gadolinium-DTPA. The results were compared with the gross and histopathologic findings and with radiography. Results. Histopathologic specimens revealed 21 osteosclerotic lesions and 5 intraosseous cysts. On 2D-SE images, 24 of 26 lesions were detected, while 21 of 26 lesions were identified on 2D-GE sequences. Radiography, including conventional tomography, demonstrated 9 of 26 lesions. Regardless of the sequence weighting, all osteosclerotic lesions appeared hypointense on MRI. Signal loss in bone sclerosis resulted primarily from the reduction of intact fat marrow, the increased bone density being of secondary importance. Quantitative signal analysis allowed approximate estimation of the grade of sclerosis. On postcontrast images, sclerotic bone remained hypointense, although significant but non-specific enhancement relative to the normal fat marrow was observed. The extent of contrast enhancement did not correlate with the grade of osteosclerosis. All five cysts were readily diagnosed by MRI. Cysts displayed either central or marginal contrast enhancement within their cavities. Conclusions. MRI provides a sensitive method for the diagnosis of osteoarthritic bone abnormalities, allowing their differentiation from most non-degenerative subarticular lesions. (orig.). With 1 tab

  11. Degenerative periodontal-diseases and oral osteonecrosis: The role of gene-environment interactions

    Chronic-degenerative dentistry diseases, including periodontal diseases and oral osteonecrosis, are widespread in human populations and represent a significant problem for public health. These diseases result from pathogenic mechanisms created by the interaction between environmental genotoxic risk-factors and genetic assets conferring individual susceptibility. Osteonecrosis occurs in subjects undergoing exposure to high doses of DNA-damaging agents for chemo- and radiotherapy of neoplastic diseases. In susceptible patients, ionizing radiation and biphosphonate-chemotherapy induce severe, progressive, and irreversible degeneration of facial bones, resulting in avascular necrosis of the jaw. This may also occur in patients receiving biphosphonate for osteoporosis therapy. Periodontal diseases include chronic, aggressive, and necrotizing periodontitis, often resulting in severe alteration of periodontal tissues and tooth loss. Cigarette smoking and chronic inflammation caused by specific bacteria are the main risk factors for periodontitis. Oxidative damage plays a fundamental pathogenic role, as established by detection of mitochondrial DNA damage in the gingival tissue of patients with periodontitis. Endogenous risk factors in dental diseases include polymorphisms for metabolic enzymes such as glutathione transferases M1 and T1, N-acetyl transferase 2, and CYP 1A1. Other genetic polymorphisms that confer susceptibility to dentistry diseases affect genes encoding metalloproteases (involved in periodontal tissue remodeling and degradation), cytokines (involved in inflammation), prothrombin, and DNA repair activities. These findings provide evidence that dentistry diseases are related to risk factors associated with environmental mutagenesis. This issue warrants future investigations aimed at improving oral health and preventing oral degenerative diseases using molecular and experimental approaches currently utilized in mutagenicity studies.

  16. The features of degenerative diseases and their association with the loss of teeth in the elderly of East Jakarta (Indonesia).

    Sudiono, Janti

    2008-01-01

    This epidemiological survey was conducted to find features of degenerative diseases associated with loss of teeth in the elderly. One hundred sixty-seven elderly (> or = 60 years old) people from local government health centers in East Jakarta, Indonesia were included in the study. The degenerative diseases (DM, hypertension, heart disease) were determined by physical examination, laboratory testing and questionnaires. Tooth loss was measured by the DMF-T (decay, missing, filling teeth) index. Oral hygiene condition was based on OHI-S (oral hygiene index simplified) index. The most common degenerative disease was hypertension (45.5%). DM was found a few (3.6%). Approximately 55% of respondents had moderate oral hygiene problems. The demand for professional dental care was low. There was no significant association between degenerative diseases and the loss of teeth. In conclusion, the loss of teeth was not associated with degenerative diseases, but may have been influenced by local factors such as a low demand for dental hygiene. PMID:18567460

  17. MR imaging of degenerative lumbar disc disease emphasizing on signal intensity changes in vertebral body

    Magnetic resonance imaging was performed in 400 patients with degenerative disc disease. Signal changes and their sites in the vertebral body were classified and referred to narrowing of the intervertebral disc space. MR findings were compared with those of plain roentgenograms of the lumbar spine. Signal changes in the vertebral body were noted in 83 cases (102 vertebral bodies). Low-intensity abnormality on both T1- and T2-weighted images (WI) was the most common finding, and was most frequently seen at the end plate and/or the angle. These changes were correlated with narrowing of the disc space and osteosclerosis on the plain roentgenogram of the lumbar spine. Signal changes occasionally occurred in the inner region of the vertebral body, and these lesions tended to show a high-intensity abnormality on T1-WI. We conclude that signal changes in degenerative disc disease are not specific, but are sometimes difficult to distinguish from the signal changes in other conditions such as spinal tumor or bone marrow disorder.

  19. Sulfato de condroitina e hialuronato de sódio no tratamento da doença articular degenerativa experimental em cães: aspectos clínicos e radiológicos Chondroitin sulfate and sodium hialuronate in treatment of the degenerative joint disease in dogs: clinical and radiological aspects

    E.G. Melo

    2003-02-01

    Full Text Available Avaliaram-se clínica e radiograficamente os efeitos do sulfato de condroitina e do hialuronato de sódio no tratamento da articulação femorotibiopatelar de cães com doença articular degenerativa (DAD induzida experimentalmente. Foram utilizados 15 cães, sem raça definida, de ambos os sexos, pesando entre 18 e 25 kg, submetidos à secção artroscópica do ligamento cruzado cranial (LCCr para desestabilização articular e indução da DAD. Após três semanas de instabilidade articular, o LCCr foi substituído utilizando-se a técnica intra-articular com emprego da fáscia lata. Os animais foram divididos em três grupos de cinco. Nos do grupo I fez-se somente a substituição do LCCr. Os do grupo II receberam 24mg/animal de sulfato de condroitina, via IM, de cinco em cinco dias, totalizando seis aplicações. Os do grupo III foram tratados com hialuronato de sódio na dose de 20mg/animal, via IV, de cinco em cinco dias, num total de três aplicações. Os animais foram observados por 90 dias, e avaliados clinicamente quanto à claudicação, à capacidade de suportar peso no membro afetado, à mensuração da atrofia muscular e à amplitude de movimento articular. Ao final, foram encaminhados para novo exame radiográfico. Os resultados demonstraram que os animais que receberam hialuronato de sódio apresentaram menor grau de claudicação quando comparados com os demais. Ao exame radiográfico observaram-se osteofitose periarticular e esclerose óssea subcondral. Essas alterações foram evidenciadas de forma mais acentuada nos animais tratados com hialuronato de sódio. Clinicamente, pôde-se observar melhor resultado com o hialuronato de sódio do que nos demais grupos, possivelmente devido à sua maior ação na membrana sinovial, reduzindo a dor e o grau de claudicação. O exame radiográfico não foi compatível com a sintomatologia clínica nos cães tratados com hialuronato de sódio.The aim of this study was the evaluation of the effects of chondroitin sulfate and sodium hyaluronate in the knee joint of dogs with experimentally induced degenerative joint disease (DJD. Fifteen mongrel dogs, weighing 18 to 25kg were used. DJD was induced by cranial cruciate ligament (CCL arthroscopical transection. After three weeks, CCL was repaired by an intrarticular technique, which uses fascia lata. The dogs were then divided into three groups as follows: group I received no other treatment, but the CCL reconstitution, group II received 24mg/animal of chondroitin sulfate/IM every five days, totaling six injections, and group III received 20mg/animal of sodium hyaluronate /IV every five days, totaling three injections. All dogs were examined clinically and radiographically for 90 days after the repairment surgery. The clinical evaluation was performed by assessment of lameness, weight-bearing, limb muscle atrophy and range of motion. The results demonstrated that the group treated with sodium hyaluronate had lower degree of lameness in comparison with other groups. The radiographic evaluation showed marginal osteophytes and subchondral bone sclerosis. These changes were more severe in the group treated with sodium hyaluronate. The better clinical results observed in this group, compared with the others, was probably due to the greater action of the drug in the synovium, decreasing the pain and lameness. Radiographic findings correlated poorly with the clinical signs in the group treated with sodium hyaluronate.

  1. Temporomandibular joint space in children without joint disease

    Bilateral assessment of the temporomandibular joint space in children without joint disease is reported. Twenty-eight children were examined with conventional radiography and 23 with tomography. High prevalence of asymmetric joint spaces with both techniques indicated that great care should be taken when using narrowing or widening of the joint space as a diagnostic criterion in children with juvenile rheumatoid arthritis. Other signs, such as restricted translation of the mandibular head, and clinical symptoms should be evaluated. (Auth.)

  2. Temporomandibular joint

    This paper determines the frequency of MR signs of abnormal temporomandibular joints (TMJs) in asymptomatic volunteers. Forty-two volunteers with 84 clinically normal TMJs were imaged in the sagittal and coronal planes with surface coil MR imaging. Sagittal closed and open and coronal closed views were obtained bilaterally in all volunteers. The images were classified as normal (superior disk position) or abnormal (disk displacement of degenerative joint disease). Eighteen joints in 11 volunteers were abnormal; 12 had disk displacement with reduction and six had disk displacement without reduction, with associated degenerative joint disease in three of the six. Asymptomatic internal derangement and degenerative joint disease occur in about one-fourth of asymptomatic volunteers

    Li, S.; Lin, A.; Tay, K.; Romano, W.; Osman, Said

    2015-03-01

    Degenerative Disc Disease (DDD) is one of the most common causes of low back pain, and is a major factor in limiting the quality of life of an individual usually as they enter older stages of life, the disc degeneration reduces the shock absorption available which in turn causes pain. Disc loss is one of the central processes in the pathogenesis of DDD. In this study, we investigated whether the image texture features quantified from magnetic resonance imaging (MRI) could be appropriate markers for diagnosis of DDD and prognosis of inter-vertebral disc loss. The main objective is to use simple image based biomarkers to perform prognosis of spinal diseases using non-invasive procedures. Our results from 65 subjects proved the higher success rates of the combination marker compared to the individual markers and in the future, we will extend the study to other spine regions to allow prognosis and diagnosis of DDD for a wider region.

  4. Histochemical and magnetic resonance imaging study of degenerative diseases in human intervertebral discs

    The aim of this study was to compare degenerative changes by means of histochemical study (with nicotinamide adenine dinucleotide phosphate diaphorase - NADPH-d) and magnetic resonance imaging (MRI) findings of degenerated human intervertebral disc (IVD). We used surgical specimens from patients undergoing surgical treatment in the lumbar region and fresh cadaveric lumbar spines for histochemical study and MRI examination of patients with low back pain. The rate of IVD degeneration depends on age, weight, abnormal mechanical load, genetics, trauma, inflammation and others. All structures from IVD (nucleus pulposus, annulus fibrosus, cartilage end plate) and the vertebral body were assessed. The histochemical study showed an increase in the intensity of NADPH-d reaction in the cells, parallel to the increase in the degree of IVD degeneration. Degenerative diseases of IVD showed different MRI findings related to the decrease in the water content of IVD, protrusion, extrusion, stenosis of vertebral canal, osteochondrosis, osteophits of the vertebral body, ossification and hypertrophy of longitudinal ligaments, Modic I and II changes and compression of the dural sac. The correlation between the histochemical results and MRI findings depended basically on aging

    Full Text Available Bacground/Aim. Diagnostic protocol for patients with degenerative diseases of the cervical spine demands, in parallel with neuroimaging methods, functional evaluation through neurophysiological methods (somatosensitive and motor evoked potentials and electromyoneurography aiming to evaluate possible subclinical affection of spinal medula resulting in neurological signs of long tract abnormalities. Considering diversities of clinical outcomes for these patients, complex diagnostic evaluation provides a prognosis of the disease progression. Methods. The study included 21 patients (48.24 ± 11.01 years of age with clinical presentation of cervical spondylarthropathy, without neuroradiological signs of myelopathy. For each patient, in addition to conventional neurophysiological tests (somatisensory evoked potentials - SSEP, motor evoked potentials - MEP, electromyoneurography - EMG, nerve conduction studies, we calculated central motor conduction time (CMCTF, as well the same parameter in relation to a different position of the head (maximal anteflexion and retroflexion, so-called dynamic tests. Results. Abnormalities of the peripheral motor neurone by conventional EMNeG was established in 2/3 of the patients, correponding to the findings of root condution time. Prolonged conventional CVMPF were found in 29% of the patients, comparing to 43% CVMPF abnormalities found with the dynamic tests. In addition, the SSEP findings were abnormal in 38% of the patients with degenerative diseases of the cervical spine. Conclusion. An extended neurophysiological protocol of testing corticospinal functions, including dynamic tests of central and periheral motor neurons are relevant for detection of subclinical forms of cervical spondylothic myelopathy, even at early stages. In addition to the conventional neurophysiological tests, we found usefull to include the dynamic motor tests and root conduction time measurement in diagnostic evaluation.

    2016-02-01

    Background and purpose - Knee arthroscopy is commonly performed to treat degenerative knee disease symptoms and traumatic meniscal tears. We evaluated whether the recent high-quality randomized control trials not favoring arthroscopic surgery for degenerative knee disease affected the procedure incidence and trends in Finland and Sweden. Patients and methods - We conducted a bi-national registry-based study including all adult (aged ?18 years) inpatient and outpatient arthroscopic surgeries performed for degenerative knee disease (osteoarthritis (OA) and degenerative meniscal tears) and traumatic meniscal tears in Finland between 1997 and 2012, and in Sweden between 2001 and 2012. Results - In Finland, the annual number of operations was 16,389 in 1997, reached 20,432 in 2007, and declined to 15,018 in 2012. In Sweden, the number of operations was 9,944 in 2001, reached 11,711 in 2008, and declined to 8,114 in 2012. The knee arthroscopy incidence for OA was 124 per 10(5) person-years in 2012 in Finland and it was 51 in Sweden. The incidence of knee arthroscopies for meniscal tears coded as traumatic steadily increased in Finland from 64 per 10(5) person-years in 1997 to 97 per 10(5) person-years in 2012, but not in Sweden. Interpretation - The incidence of arthroscopies for degenerative knee disease declined after 2008 in both countries. Remarkably, the incidence of arthroscopy for degenerative knee disease and traumatic meniscal tears is 2 to 4 times higher in Finland than in Sweden. Efficient implementation of new high-quality evidence in clinical practice could reduce the number of ineffective surgeries. PMID:26122621

    The magnetic resonance imaging findings recorded in patients after surgery for degenerative disc disease in the lumbar and cervical spine are discussed in comparison with conventional radiographs and computed tomography findings. In the lumbar spine normal postoperative findings in the immediate postoperative period can be demonstrated by MR imaging. Contrast-enhanced MR imaging can differentiate disc herniation from postoperative scar formation with a greater degree of confidence than other imaging modalities. MR imaging improves differentiation between other causes of failed back syndrome such as postoperative hematoma and infection, lateral spinal stenosis and arachnoiditis. In the cervical spine types of operative approaches, the appearance of bony stenosis and disc herniations by MR imaging are discussed. Computer tomography still has a role in the assessment of osseous complications such as central or foraminal stenosis. (orig.)

    2014-04-01

    Full Text Available Cardiac diseases promote alterations in the autonomic control of the heart, leading to an increase in heart rate and, as a result, a decrease in heart rate variability (HRV.The aim of this study was to evaluate if the development of heart failure secondary to degenerative mitral valve disease (DMVD concurs with changes in autonomic modulation of heart rhythm which are assessed by long electrocardiography examination (Holter. Dogs were evaluated by clinical examination and echocardiography in order to be categorized into the following groups: Control (healthy; n=6, DMVD (disease without heart failure; n=8, and DMVD heart failure (disease with heart failure; n=13. Arrhythmias and frequency domain HRV were determined by Holter. Diseased animals, when compared to healthy, had significantly lower total power, which indicates overall HRV. DMVD heart failure dogs also showed other disturbances such as high incidence of supraventricular arrhythmias, high heart rate, little amount of pauses (2.0s long between consecutive heartbeats, longer time in tachycardia, shorter time in bradycardia, low high frequency (parasympathetic control, and high low frequency (sympathetic and parasympathetic control when compared to control (p<0.05. In DMVD dogs, Holter-derived variables changed with the development of heart failure.

    [Purpose] This study was conducted to examine the association between Modic classification and the eating habits in patients with degenerative disc disease (DDD) and to determine the influence of nutrition on disease severity. [Subjects and Methods] Sixty patients with DDD visiting a low back pain outpatient clinic were enrolled. Through face-to-face interviews, they completed questionnaires regarding their demographics, disease activity, smoking and alcohol use, concomitant diseases, disease duration, and nutritional status.Exclusion criteria were age 65 years, other comorbidities, missing MRI data, and inability to speak Turkish. [Results] Forty patients were finally included in the study. The frequency with which they consumed water, salt, fast food, eggs, milk, yogurt, cheese, whole wheat bread, white bread, butter, and margarine was recorded. A weak negative correlation was observed between the Modic types and fish and egg consumption. [Conclusion] Modic changes, which indicate the severity of DDD, seem to be correlated to patients’ dietary habits. However, studies with comparison groups and larger samples are needed to confirm our promising results before any cause-and-effect relationship can be proposed. PMID:27190462

    2015-03-01

    Lumbosacral transitional vertebrae (LTV) frequently occur in German shepherd dogs. The aim of the study was to evaluate the prevalence and interdependence between LTV and canine hip dysplasia (CHD) as well as sacroiliac joint degenerative changes visualized on ventrodorsal radiographs of the pelvis in both working and companion German shepherd dogs. The presence of LTV was found in 12% of working dogs and in 33% of companion dogs. Similar incidence of hip dysplasia in both the groups was found. It has been shown that dogs with LTV have a higher frequency of severe CHD. A higher percentage of sacroiliac joint degenerative changes was observed in dogs with no signs of LTV and in working dogs. PMID:26041591

  11. Gd-DTPA-enhanced Three-dimensional MR imaging of degenerative disease of the cervical spine

    This paper assesses cervical spine three-dimensional (3D) MR imaging with Gd-DTPA, with the hypothesis that an enhanced 3D sequence with reconstructions would suffice for the evaluation of degenerative disease. Sixty patients were examined with (1) T1-weighted spin-echo and axial 2D gradient-echo low-flip-angle images representing the standard examination; and (2) one of two different enhanced 3D gradient-echo techniques: 30 patients with 3D fast low-angle shot (FLASH) imaging (TR 40/TE 7, 40 degrees flip angle, 64 2-mm sagittal partitions, one excitation, 10:67 minutes) and 30 with 3D Turbo FLASH imaging (MP RAGE) (7/5, 10 degrees, 128 1.5-mm partitions, one excitation, 6:07 minutes). 3D studies were reconstructed at 45 degrees obliquities for foramina, and axially. Standard and 3D studies were evaluated independently by two neuroradiologists for the location and size of extradural disease

    Gupta, Vivek K; Chitranshi, Nitin; Gupta, Veer B; Golzan, Mojtaba; Dheer, Yogita; Wall, Roshana Vander; Georgevsky, Dana; King, Anna E; Vickers, James C; Chung, Roger; Graham, Stuart

    2016-06-01

    The APP-PS1ΔE9 mouse model of Alzheimer's disease (AD) exhibits age dependent amyloid β (Aβ) plaque formation in their central nervous system due to high expression of mutated human APP and PSEN1 transgenes. Here we evaluated Aβ deposition and changes in soluble Aβ accumulation in the retinas of aged APP-PS1 mice using a combination of immunofluorescence, retinal flat mounts and western blotting techniques. Aβ accumulation in the retina has previously been shown to be associated with retinal ganglion cell apoptosis in animal models of glaucoma. This study investigated changes in the inner retinal function and structure in APP-PS1 mice using electrophysiology and histological approaches respectively. We report for the first time a significant decline in scotopic threshold response (STR) amplitudes which represents inner retinal function in transgenic animals compared to the wild type counterparts (p<0.0001). Thinning of the retina particularly involving inner retinal layers and reduction in axonal density in the optic nerve was also observed. TUNEL staining was performed to examine neuronal apoptosis in the inner retina. Intraocular pressure (IOP) measurements showed that APP-PS1ΔE9 mice had a slightly elevated IOP, but the significance of this finding is not yet known. Together, these results substantiate previous observations and highlight that APP-PS1ΔE9 mice show evidence of molecular, functional and morphological degenerative changes in the inner retina.

  14. Quantitative analysis of CT scan in degenerative diseases of the nervous system

    Quantitative analysis was made on cranial CT scans of 142 patients with spinocerebellar degeneration (SCD), 16 with dentato-rubro-pallido-luysian atrophy (DRPLA), 12 with Huntington's chorea (HC), and four with chorea-acanthocytosis (CA). One hundred sex- and age-matched persons without any neurologic signs served as controls. Regarding parameters for atrophy in the infratentorial brain tissue, there was statistically significant difference between the SCD group and the control group. This indicated remarkable atrophy in the cerebellum and brain stem in SCD. According to subgroups of SCD, both bilateral atrophy of the pons and dilation of the prepontine cistern were significantly greater in the group of sporadic olivo-ponto-cerebellar atrophy than the group of Menzel type of olivo-ponto-cerebellar atrophy. The subgroup of hereditary spastic paraplegia had the mildest atrophy of the brain on CT, although there was still a significant atrophy compared with controls. In the DRPLA group, finding in the infratentorial brain tissue were similar to those in the SCD group. The HC group was characterized by having the greatest atrophy in the lateral ventricle, especially the caudate nuclei. Similar findings were seen in the CA group, although atrophy was generally mild. The results indicate the usefulness of quantitative analysis on CT in the diagnosis of degenerative diseases of the nervous system. (Namekawa, K.)

    Full Text Available Many different groups have expressed the need to standardize the terms and classifications used in the reporting of spine MRI, particularly in the lumbar spine."nSeveral studies have shown "moderate" (17-20% ob-server variations in MRI lumbar spine reporting. The main discrepancies occur when deciding what consti-tutes a bulging or herniated disc and this represents more than 50% of all inter-observer disagreement. A variety of different terms are used to describe disc pathology on the preference of the reporting individ-ual."nRecently, there is a universal consensus of terms and a nomenclature framework for degenerative disc dis-ease which using of them are encouraged by the American Society of Neuroradiology (ASNR."nIn this presentation, first some inter-observer varia-tions of MRI reporting in our center will be shown. "nThen a review of articles about standard MRI report-ing nomenclature with some relevant interesting cases from our MRI center will be presented.

  16. Radiopharmaceuticals for SPECT exploration of dopaminergic systems. Diagnosis and surveillance of neuro-degenerative diseases

    New radiopharmaceuticals were developed to explore the pre- or post-synaptic slopes of the dopaminergic terminations. At present, their interest is recognized for the differential diagnosis of the extra-pyramidal syndromes. Other various applications in neurology and psychiatry are in view. On the pre-synaptic slope, implied in the Parkinson's disease, the dopamine carrier, able to be visualized due to its iodine derivatives of cocaine, is localized. The βCIT, which is presently the best known specificity-free derivative, has actually an equivalent affinity for the dopamine carrier and the serotonin carrier. Besides, its kinetic does not allow its imaging in the day of injection. We have developed and validated another derivative, the PE2I: N-(3-Iodoprop-(2E)-enyl) -2β-carbometoxy -3β-(4'-methyl-phenyl) nortropane which displays the properties required by kinetic and specificity. On the post-synaptic slope the type-D2 dopaminergic receptors were localized, which can be explored by means of (iodolisuride) ergolenes and benzamide derivatives (IBZM). These ligands have not an AMM yet, therefore their utilization may be approached by magistral preparation. The scintigraphy of the D2 receptors and dopamine carrier could be useful for the earlier diagnosis and the therapeutic surveillance of the neuro-degenerative decease. The coupling of the pre- and post-synaptic scintigraphies may be taken into consideration to augment diagnosis potentiality

  17. Radiographic evaluation of the use of transverse traction device in vertebral arthrodesis for degenerative diseases

    2014-03-01

    Full Text Available OBJECTIVE: Perform radiographic analysis of the use of Transverse Traction Device (DTT with respect to fusion rate in patients submitted to vertebral arthrodesis for degenerative lumbar diseases. METHODS: We selected x-ray images on anteroposterior, lateral and oblique views and with maximum flexion and extension dynamics of 23 patients submitted to posterolateral arthrodesis of the lumbar spine with a minimum follow-up period of six months. The images were evaluated and classified by the Linovitz's system by two spine surgeons. RESULTS: We evaluated the radiographs of 23 patients after the minimum postoperative period of 6 months and of these, 11 have used DTT. With regard to the consolidation rate, seven patients (63.6% in the group of DTT were classified as fusion as well as six patients (50% who were not submitted to the treatment. There was no statistical difference between the groups regarding the consolidation rate. CONCLUSION: The use of transverse traction device in this study showed no significant difference in the rate of consolidation in radiographic evaluation. Studies on the effective participation of this device in the stability of pedicle fixation systems are still lacking in the literature.

  19. Radiosynoviorthesis in haemaphilic joint disease

    van' t Pad Bosch, P.J.I.; van de Putte, L.B.A.; Boerbooms, A.M.T.; Geerdink, P.J.

    The effects of radiosynoviorthesis on chronic haemophilic arthropathic joints were studied in six patients with severe haemophilia by a follow up study which spanned two and a half years. On clinical grounds the treatment was successful because pain and bleeding frequency diminished, although radiographic examination showed further deterioration of the treated joint. Chromosome damage was not detected. We conclude that radiosynoviorthesis is apparently changing the bleeding pattern of articular tissues without arresting the destruction and deformation of joints.

  1. Plain-film diagnosis of joint disease

    The authors describe a systematic approach to plain-film diagnosis of joint disease. The major radiologic criteria - soft-tissue swelling, joint-space narrowing, bone erosion, bone sclerosis and osteophytosis, and chondrocalcinosis - are considered first. Assessing the involvement of the minor criteria of joint disease - soft-tissue atrophy or calcification, malalignment, osteoporosis, abnormal growth, intra-articular bony ankylosis, bon fragmentation, periostitis, subperiosteal resorption or acro-osteolysis -narrows the probabilities to the more likely diagnoses. Further analysis includes the distribution of joint injury, whether mono- or polyarticular, symmetrical or asymmetrical. Added to clinical information, this approach leads to a specific or refined differential diagnosis. (47 refs., 11 figs.)

  3. Back pain in patients with degenerative spine disease and intradural spinal tumor: What to treat? When to treat?

    Bellut, David; Mutter, Urs M; Sutter, Martin; Eggspuehler, Andreas; Mannion, Anne F; Porchet, François

    2014-01-01

    BACKGROUND: Back pain is common in industrialized countries and one of the most frequent causes of work incapacity. Successful treatment is, therefore, not only important for improving the symptoms and the quality of life of these patients but also for socioeconomic reasons. Back pain is frequently caused by degenerative spine disease. Intradural spinal tumors are rare with an annual incidence of 2-4/1,00,000 and are mostly associated with neurological deficits and radicular and nocturnal pai...

  4. Prevalence of degenerative and spondyloarthritis-related magnetic resonance imaging findings in the spine and sacroiliac joints in patients with persistent low back pain

    To estimate the prevalence of degenerative and spondyloarthritis (SpA)-related magnetic resonance imaging (MRI) findings in the spine and sacroiliac joints (SIJs) and analyse their association with gender and age in persistent low back pain (LBP) patients. Degenerative and SpA-related MRI findings in the whole spine and SIJs were evaluated in Spine Centre patients aged 18-40 years with LBP. Among the 1,037 patients, the prevalence of disc degeneration, disc contour changes and vertebral endplate signal (Modic) changes were 87 % (±SEM 1.1), 82 % (±1.2) and 48 % (±1.6). All degenerative spinal findings were most frequent in men and patients aged 30-40 years. Spinal SpA-related MRI findings were rare. In the SIJs, 28 % (±1.4) had at least one MRI finding, with bone marrow oedema being the most common (21 % (±1.3)). SIJ erosions were most prevalent in patients aged 18-29 years and bone marrow oedema in patients aged 30-40 years. SIJ sclerosis and fatty marrow deposition were most common in women. SIJ bone marrow oedema, sclerosis and erosions were most frequent in women indicating pregnancy-related LBP. The high prevalence of SIJ MRI findings associated with age, gender, and pregnancy-related LBP need further investigation of their clinical importance in LBP patients. (orig.)

  5. Occupational diseases of skeleton and bone joints

    The essence of roentgeno-morphological features of locomotor system occupational diseases lies in development of dystrophic, degenerative and necrotic processes. Pathological changes take place during vibration, recoil and strain as well as under the effect of unfavourable microclimate (high humidity, cold), vibration being the most important as compared to other harmful factors. Detailed sanitary-and-hygienic and labour characteristics of working conditions of personnel, subjected to the effect of those factors as well as roentgenological characteristics of locomotor system occupational changes are given

    Full Text Available Objective: We aimed to investigate the efficacy of intradiscal steroid injection in patients with chronic low back pain due to degenerative disc disease.Materials and Methods: A total of 18 patients (9 female, 9 male with chronic low back pain of discogenic origin were enrolled in the study. The intervertebral disc level which met the diagnostic criteria for provocative discography was defined as discogenic pain level. After identification of positive disc level, 1 cc betamethasone was injected into the disc. The outcome measures (visual analog pain scale and Quebec Back Pain Disability Scale scores, finger-tip-to-floor distance and duration of sitting without pain were assessed before the treatment and at second week and third month post injection. Results: The reduction in low back pain intensity between the baseline and second week, and between the baseline and third month was statistically significant (p=0.001 and p=0.002. Besides, statistically significant improvement was observed in Quebec Disability Scores between the baseline and second week, and between the baseline and third month (p=0.001 and p=0.002. The finger-tip-to-floor distance between the baseline and second week, and between the baseline and third month showed a statistically significant improvement (p=0.002 and p=0.02. The duration of sitting without pain between the baseline and second week, and between the baseline and third month showed a statistically significant increase (p=0.001 and p=0.009. Conclusion: As a result, we suggest that intradiscal steroid injection may be effective in short-term and mid-term for reducing the intensity of spinal pain and the proportion of disability due to chronic discogenic low back pain in patients who do not respond to conservative treatment.

  7. Haemophilia and joint disease: pathophysiology, evaluation, and management

    Karen Knobe

    2011-12-01

    Full Text Available In patients with haemophilia, regular replacement therapy with clotting factor concentrates (prophylaxis is effective in preventing recurrent bleeding episodes into joints and muscles. However, despite this success, intra-articular and intramuscular bleeding is still a major clinical manifestation of the disease. Bleeding most commonly occurs in the knees, elbows, and ankles, and is often evident from early childhood. The pathogenesis of haemophilic arthropathy is multifactorial, with changes occurring in the synovium, bone, cartilage, and blood vessels. Recurrent joint bleeding causes synovial proliferation and inflammation (haemophilic synovitis that contribute to end-stage degeneration (haemophilic arthropathy; with pain and limitation of motion severely affecting patients quality of life. If joint bleeding is not treated adequately, it tends to recur, resulting in a vicious cycle that must be broken to prevent the development of chronic synovitis and degenerative arthritis. Effective prevention and management of haemophilic arthropathy includes the use of early, aggressive prophylaxis with factor replacement therapies, as well as elective procedures, including restorative physical therapy, analgesia, aspiration, synovectomy, and orthopaedic surgery. Optimal treatment of patients with haemophilia requires a multidisciplinary team comprising a haematologist, physiotherapist, orthopaedic practitioner, rehabilitation physician, occupational therapist, psychologist, social workers, and nurses.

    2015-11-01

    Full Text Available : BACKGROUND: Low back pain (LBP is a common presenting complaint affecting mostly middle aged and older person and traditionally considered as ageing process, but now-a-days large number of younger people are also affected by this debilitating chronic disorder. The cause of early onset of degenerative spine disease is multifactorial, but genetical predisposition plays very important role. AIMS AND OBJECTIVE: To find out association between genetic predisposition and degenerative spine disease in adult patients and to assess the pattern of MRI findings of various degenerative diseases in lumbo-sacral spine. MATERIAL AND METHOD: The present cross-sectional study had been performed among 100 selected patients in 1yr period, who presented with chief complaint of chronic low back pain. After taking detailed clinical and professional history, MRI of lumbosacral spine had been performed. Total 100 patients were divided in two groups on the basis of genetical predisposition. Prevalence and spectrum of degenerative changes were compared between both groups. RESULTS: Hundred patients of 20 to 35-year age had been selected with mean age of 27yr. Out of 100 patients; 47 were male and 53 were female. The most common degenerative findings were desiccation of disc (95% followed by disc bulge, herniation, spinal canal stenosis, ligamentum flavum hypertrophy, facet joint hypertrophy and modic changes. L4-L5 and L5- S1 were the most commonly involved spinal levels for any degenerative pathology. CONCLUSION: Good association is seen between early onset of degenerative spine disease and genetical predisposition in patients who have history of similar type degenerative spine disease in one or more first degree relatives in comparison to those patients who do not have any genetical predisposition. So it can be concluded that heredity play important role in early onset of degenerative spine disease in adults.

  10. Bone-to-bone, joint-to-bone and joint-to-joint ratios in normal and diseased states using region-of-interest technique and bone-seeking radiopharmaceuticals

    Bone-to-bone, iliosacral joints-to-os sacrum and joint-to-joint ratios were computed using the region-of-interest technique 2 to 3 hrs. after injection of sup(99m)Tc Sn-methylene-diphosphonate or sup(99m)Tc Sn-pyrophosphate in 139 patients with skeletal diseases (bone tumours, degenerative changes of the spine and joints, inflammatory changes of joints) as well as in 123 patients with normal skeletal states.In the latter group, iliosacral joints-to-os sacrum ratios decreased with increasing age of the patients. In patients with osseous metastases of the spine ratios of 0.80 to 4.0 occurred (reference area second vertebra below or above the affected vertebra). In degenerative changes of the spine values of 0.80 to 1.69 were computed. These results show, that 74% of the spine metastases could not be differentiated from benign changes of the spine by determining their relative amounts of bone uptake. In bone tumours of the extremities and in rheumatoid or gouty arthritis of the small joints (hands and fect) the highest ratios, i.e. contrasts, occured referring to a contralateral reference area. Osteoarthritic and inflammatory alterations of the big joints could not be differentiated because the percentual distribution of the increased joint-to-joint ratios turned out to be nearly identical.

  11. The Mircen project, neuro-degenerative disease: mechanisms, therapeutics and imaging research Unit URA Cea Cnrs 2210

    During the post-genomic era, significant advances in our understanding of the molecular basis of disease have been made. The power of functional and molecular imaging in translating this knowledge into effective therapy is now being more and more recognized. Thus, molecular imaging plays a vital role in the early identification of disease-related molecular markers, in the development of molecular-targeted therapies, and in monitoring phenotypic response to therapy both in experimental animals and in human patients. In this context, MIRCen (acronym for Molecular Imaging Research Center ) provides a comprehensive resource available to empower basic, translational, and clinical research through the application of imaging and drug, cell, and gene based technologies. The MIR center will be dedicated to the development of pre-clinical trials for the treatment of various seriously debilitating diseases such as neuro-degenerative diseases, cardiac and hepatic disorders, and infectious diseases (AIDS). Despite the fact that many of these pathologies are still incurable, recent advances in drug, cell and gene therapy point to the feasibility of new therapeutic approaches. The long term goals of MIRCen are therefore to develop and validate: - pertinent animal models for neuro-degenerative, hepatic, cardiac and infectious diseases in rodents as well as non-human primates, - novel technologies for in vivo sensing and imaging of disease-related molecular events,- drug, gene and cell based palliative and or curative therapeutic strategies aiming at protecting and /or restoring damaged or lost functions.

    Full Text Available Objective. Although trace elements are regarded crucial and their content has been determined in number of tissue there are only few papers addressing this problem in intervertebral disc in humans. Most of the trace elements are important substrates of enzymes influencing metabolism and senescence process. Others are markers of environmental pollution. Therefore the aim of the research was to analyzed of the trace element content in the intervertebral disc, which may be a vital argument recognizing the background of degenerative changes to be the effect of the environment or metabolic factors. Materials and methods. Material consist of 18 intervertebral disc from 15 patients, acquired in surgical procedure of due to the degenerative disease with Atomic Absorption Spectrometry content of Al, Cd, Co, Pb, Cu, Ni, Mo, Mg, Zn was evaluated. Results. Only 4 of the trace elements were detected in all samples. The correlation analysis showed significant positive age correlation with Al and negative in case of Co. Among elements significant positive correlation was observed between Al/Pb, Co/Mo, Al/Mg, Al/Zn Pb/Zn and Mg/Zn. Negative correlation was observed in Al/Co, Cd/Mg, Co/Mg, Mo/Mg, Co/Zn and Mo/Zn. Conclusions. This study is the first to our knowledge that profiles the elements in intervertebral disc in patients with degenerative changes. We have confirmed significant differences between the trace element contents in intervertebral disc and other tissue. It can be ground for further investigation.

    The most frequent rheumatic joint disease in the elderly is rheumatoid arthritis (RA). Recent advances in the treatment of RA improve prognosis, and gradually increase the elderly patients with RA. There are some differences in clinical features between the patients with elderly onset RA and young onset RA, such as systemic symptoms and distribution of affected joints. In addition, it is occasionally difficult to differentiate elderly onset RA from the other rheumatic diseases like polymyalgia rheumatica and RS3PE syndrome, pseudogout, and osteoarthritis. Since elderly patients tend to have more co-morbidity and co-existing diseases requiring treatment with other drugs, a risk/benefit profile must always be taken into consideration when choosing the treatment in elderly patients with rheumatic joint diseases.

  15. Osseous temporomandibular joint abnormalities in rheumatic disease

    Computed tomography (CT) of the temporomandibular joint (TMJ) was compared with hypocycloidal tomography in 30 joints of 15 adults with rheumatic disease. CT included 1.5 mm thick axial scans (at 1.0 mm intervals) with reformatted oblique sagittal and oblique coronal sections. Multisection (at 2.0 mm intervals) tomography included oblique sagittal and occasionally, oblique coronal sections. CT demonstrated bone abnormalities in 21 and tomography in 20 joints, indicating high agreement between the imaging modalities regarding number of abnormal TMJs. Bone structures were, however, better visualized by multiplanar CT due to superior contrast and spatial resolution particularly in the most lateral and medial parts of the joint, indicating superiority of CT for depicting subtle bony TMJ abnormalities in patients with rheumatic disease.

  17. Joint disease in children of Asiatic origin

    Joint disorders in Asian children are varied due to the diversity of the Asian population and show some ethnic trends. The ethnic diversity, socio-economic and geographic factors in Asia have limited the availability of data from some of the ethnic groups, many of whom live in remote and relatively underdeveloped areas, are not subjected to epidemiological surveillance and have little awareness of these diseases and their consequences. Geographic and socio-economic factors also play a significant role in some of the joint diseases peculiar to Asian children. In general, the current available data suggests that there are no large differences in the epidemiology and clinical features between the Western and Asian children. This article reviews the available literature on joint diseases in Asian children

    Primary or secondary degeneration of the articular cartilage induces subchondral bone remodelling, which can be recognized in the bone scan by an enhanced radionuclide uptake. It cannot be distinguished from radionuclide uptake caused by other bone affections. Thus the scintigraphic diagnosis of degenerative bone disease bases essentially on the consideration of its sites of predilection. Degenerative bone changes can be differentiated from inflamation or osteonecrosis by three-phase bone scans. As SPECT provides imaging without superposition, this technique should be preferably used in the detection of degenerative changes of the vertebral column. (orig.) [Deutsch] Durch primaere oder sekundaere Degeneration des Gelenkknorpels werden subchondrale Knochenumbauprozesse eingeleitet, die im Szintigramm an einer vermehrten Akkretion zu erkennen sind. Sie sind nicht von Mehranreicherungen aufgrund anderer Knochenaffektionen zu unterscheiden. Der szintigraphische Nachweis degenerativer Skelettveraenderungen beruht daher wesentlich auf der Beruecksichtigung ihrer Praedilektionsstellen. Mit der Drei-Phasen-Skelett-Szintigraphie lassen sich degenerative Veraenderungen von entzuendlichen Prozessen oder Osteonekrosen abgrenzen. Durch die SPECT koennen die dicht beieinanderliegenden Strukturen der Wirbelsaeule ueberlagerungsfrei dargestellt werden. Daher sollte zum Nachweis degenerativer Veraenderungen der Wirbelsaeule bevorzugt diese Methode eingesetzt werden. (orig.)

LBP caused by sacroiliac (SI joint disruption/degenerative sacroiliitis is most commonly treated with nonoperative care and/or open SI joint surgery. New and effective minimally invasive surgery (MIS options may offer potential cost savings to Medicare.Methods: An economic model was developed to compare the costs of MIS treatment to nonoperative care for the treatment of SI joint disruption in the hospital inpatient setting in the US Medicare population. Lifetime cost savings (2012 US dollars were estimated from the published literature and claims data. Costs included treatment, follow-up, diagnostic testing, and retail pharmacy pain medication. Costs of SI joint disruption patients managed with nonoperative care were estimated from the 2005–2010 Medicare 5% Standard Analytic Files using primary International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM diagnosis codes 720.2, 724.6, 739.4, 846.9, or 847.3. MIS fusion hospitalization cost was based on Diagnosis Related Group (DRG payments of $46,700 (with major complications - DRG 459 and $27,800 (without major complications - DRG 460, weighted assuming 3.8% of patients have complications. MIS fusion professional fee was determined from the 2012 Medicare payment for Current Procedural Terminology code 27280, with an 82% fusion success rate and 1.8% revision rate. Outcomes were discounted by 3.0% per annum.Results: The extrapolated lifetime cost of treating Medicare patients with MIS fusion was $48,185/patient compared to $51,543/patient for nonoperative care, resulting in a $660 million savings to Medicare (196,452 beneficiaries at $3,358 in savings/patient. Including those with ICD-9-CM code 721.3 (lumbosacral spondylosis increased lifetime cost estimates (up to 478,764 beneficiaries at $8,692 in savings/patient.Conclusion: Treating Medicare beneficiaries with MIS fusion in the hospital inpatient setting could save Medicare $660 million over patients' lifetimes.Keywords: sacroiliac joint disruption, degenerative sacroiliitis, minimally invasive surgery, epidural injection, iFuse, cost

    2002-07-01

    The objective of this retrospective study was to evaluate the long-term clinical outcomes and the effects on unfused motion segments of posterolateral fusion. This study involved 35 cases (37 intervertebral levels) of posterolateral fusion performed to treat degenerative lumbar spinal diseases. There were 20 male and 15 female patients ranging in age from 30 to 67 years, with a mean age of 49 years. The postoperative period ranged from 10 years to 17 years and 8 months, with a mean period of 13 years. The clinical outcomes were evaluated using the Japanese Orthopaedic Association (JOA) score for assessment of treatment for low back pain. The effects on unfused motion segments were investigated with radiographic and magnetic resonance (MR) imaging. Postoperative satisfactory improvement (mean recovery rate, 66.9%) reached a plateau at 1 year and was maintained at final follow-up. Radiographically, the union rate was 86.5%. There were few cases of induced instability of unfused motion segments. On MR imaging, increased signal intensity in both T{sub 1}- and T{sub 2}-weighted images was seen in the paravertebral muscles in 15 of 20 cases (75.0%). Posterolateral fusion is a useful technique for the treatment of degenerative lumbar spinal diseases. Clinical outcomes were stable throughout follow-up. Instability of unfused motion segments rarely occurred. (author)

    Full Text Available In the treatment of multilevel degenerative disorders of the lumbar spine, spondylodesis plays a controversial role. Most patients can be treated conservatively with success. Multilevel lumbar fusion with instrumentation is associated with severe complications like failed back surgery syndrome, implant failure, and adjacent segment disease (ASD. This retrospective study examines the records of 70 elderly patients with degenerative changes or instability of the lumbar spine treated between 2002 and 2007 with spondylodesis of more than two segments. Sixty-four patients were included; 5 patients had died and one patient was lost to follow-up. We evaluated complications, clinical/radiological outcomes, and success of fusion. Flexion-extension and standing X-rays in two planes, MRI, and/or CT scans were obtained pre-operatively. Patients were assessed clinically using the Oswestry disability index (ODI and a Visual Analogue Scale (VAS. Surgery performed was dorsolateral fusion (46.9% or dorsal fusion with anterior lumbar interbody fusion (ALIF; 53.1%. Additional decompression was carried out in 37.5% of patients. Mean follow-up was 29.4±5.4 months. Average patient age was 64.7±4.3 years. Clinical outcomes were not satisfactory for all patients. VAS scores improved from 8.6±1.3 to 5.6±3.0 pre- to post-operatively, without statistical significance. ODI was also not significantly improved (56.1±22.3 pre- and 45.1±26.4 post-operatively. Successful fusion, defined as adequate bone mass with trabeculation at the facets and transverse processes or in the intervertebral segments, did not correlate with good clinical outcomes. Thirty-five of 64 patients (54% showed signs of pedicle screw loosening, especially of the screws at S1. However, only 7 of these 35 (20% complained of corresponding back pain. Revision surgery was required in 24 of 64 patients (38%. Of these, indications were adjacent segment disease (16 cases, pedicle screw loosening (7 cases, and infection (one case. At follow-up of 29.4 months, patients with radiographic ASD had worse ODI scores than patients without (54.7 vs. 36.6; P less than 0.001. Multilevel fusion for degenerative disease still has a high rate of complications, up to 50%. The problem of adjacent segment disease after fusion surgery has not yet been solved. This study underscores the need for strict indication guidelines to perform lumbar spine fusion of more than two levels.

  3. Development of PET tracers for neuro inflammation imaging in neuro degenerative diseases

    Inflammatory processes such as micro-glial or endothelial activation are involved in many neuro-degenerative conditions. Neuro-inflammation imaging is considered an attractive tool for fundamental research, diagnosis and therapeutic evaluation in neuro-pathologies. First, an aptamer was selected against a recombinant fragment of the endothelial target VCAM-1, but proved unable to bind the target protein in native conformation, as expressed by a cell line. Second, five radioligands of the peripheral benzodiazepine receptor (PBR), a marker of micro-glial activation, were evaluated in vivo using PET (Positron Emission Tomography) imaging in a rat model of neuro-inflammation, and were compared to [11C]PK11195. Four radiotracers displayed a better contrast than [11C]PK11195. In a competitive field of research, this work demonstrates the efficiency of in vivo screening of radiotracers for fast selection of clinically relevant molecules. (author)

    The Rett syndrome is a progressive disorder which is associated with regression of psychomotor development and precipitous deceleration of brain growth during the first year of life. General histopathological surveys in postmortem specimens have identified degeneration of subpopulations of neurons of the nigrostriatal system but no other evidence of degenerative process. Magnetic resonance imaging-based morphometry may usefully guide application of rigorous but demanding quantitative histologic search for evidence of neuronal degeneration. The volumes of the principal set of cortical and nuclear structures of principal interest in the disorder may be measured by currently avaiable MRI-based methods. Opimized levels of precision now allow detection of volumetric changes over time in the same brain of approximately 10% at the 95% confidence level. (author).

    Objective: To determine the accuracy of ultrasonography (US) in the evaluation of degenerative changes in the distal radioulnar joint (DRUJ). Methods and materials: Ten cadaveric specimens were obtained. US evaluation of cartilage degeneration and thickness was performed by two independent and blinded readers (R1 and R2). Gross anatomy and MR arthrography evaluated by two readers in consensus served as the reference standard. The joint surface not accessible to US was measured. Results: US interreader agreement was non-existent for cartilage thickness measurements and moderate for cartilage degeneration grading (weighted kappa = 0.41). Comparing US and MR imaging evaluation, there was no correlation between US R1 and MR imaging (Pearson correlation coefficient [PCC] = 0.352) and a moderate correlation between US R2 and MR imaging (PCC = 0.570) concerning cartilage thickness measurements. Concerning cartilage degeneration grading, there was a moderate to strong (R1 Spearman correlation coefficient [SCC] = 0.729)/R2 SCC = 0.767) correlation concerning cartilage degeneration grading. Comparing US and gross anatomic evaluation, there was no correlation for US R1 (PCC = 0.220) and a strong correlation for US R2 (PCC = 0.922) concerning cartilage thickness measurements, and a strong to moderate correlation (R1 SCC = 0.808/R2 SCC = 0.597) concerning cartilage degeneration grading. The mean sector of the articular surface of the ulna head not accessible to US was 13{sup o}. Conclusion: In conclusion the DRUJ is accessible to US except in the central 13{sup o} sector of the joint surface. US was approved to be sufficient in demonstrating advanced stages of cartilage degeneration. Thus, US of the DRUJ is recommended in patients suffering from ulnar-sided wrist pain.

  9. Degenerative disease of the cervical spine and its relationship to athletes.

    Triantafillou, Konstantinos M; Lauerman, William; Kalantar, S Babak

    2012-07-01

    Each sport presents with unique risk factors and different mechanisms of injury, and therefore extrapolation of the data from one sport to another makes comparison difficult. The current evidence exploring the relationship of athletes and degenerative changes of the cervical spine leaves much to be debated, and future prospective longitudinal studies will be needed to clarify our understanding further. Such research will help structure clinical recommendations and improve sports safety and the care of athletes of all ages. Currently, there is evidence to suggest that participation in collision sports is implicated in premature degeneration of the cervical spine. There is some evidence to suggest that the same is true with noncollision sports and activities that result in direct and indirect repetitive loads to the cervical spine over time. The risk factors have yet to be clearly identified. The natural history and sequelae of premature degeneration have yet to be elucidated. Cervical spondylosis also appears to increase the severity, but not the frequency, of irreversible neurologic injury during collision sport participation. Prudence dictates that we not ignore the present evidence suggesting a link between neuropraxia and cervical stenosis. Proper screening for cervical stenosis in patients with transient neuropraxia with subsequent cessation of participation in collision sports if severe stenosis is present is suggested. There is no consensus for RTP guidelines in the setting of transient neurologic injuries in the athlete when severe degeneration is present, and each case must be considered individually with regard to the sport involved.

Traditional SI joint disruption/degenerative sacroiliitis treatments include nonoperative care or open SI joint fusion. To evaluate the usefulness of newly developed minimally-invasive technologies, the costs of traditional treatments must be better understood. We assessed the costs of nonoperative care for SI joint disruption to commercial payers in the United States (US. Methods: A retrospective study of claim-level medical resource use and associated costs used the MarketScan Commercial Claims and Encounters as well as Medicare Supplemental Databases of Truven Healthcare. Patients with a primary ICD-9-CM diagnosis code for SI joint disruption (720.2, 724.6, 739.4, 846.9, or 847.3, an initial date of diagnosis from January 1, 2005 to December 31, 2007 (index date, and continuous enrollment for ?1 year before and 3 years after the index date were included. Claims attributable to SI joint disruption with a primary or secondary ICD-9-CM diagnosis code of 71x.xx, 72x.xx, 73x.xx, or 84x.xx were identified; the 3-year medical resource use-associated reimbursement and outpatient pain medication costs (measured in 2011 US dollars were tabulated across practice settings. A subgroup analysis was performed among patients with lumbar spinal fusion. Results: The mean 3-year direct, attributable medical costs were $16,196 (standard deviation [SD] $28,592 per privately-insured patient (N=78,533. Among patients with lumbar spinal fusion (N=434, attributable 3-year mean costs were $91,720 (SD $75,502 per patient compared to $15,776 (SD $27,542 per patient among patients without lumbar spinal fusion (N=78,099. Overall, inpatient hospitalizations (19.4%, hospital outpatient visits and procedures (14.0%, and outpatient pain medications (9.6% accounted for the largest proportion of costs. The estimated 3-year insurance payments attributable to SI joint disruption were $1.6 billion per 100,000 commercial payer beneficiaries. Conclusion: The economic burden of SI joint disruption among privately-insured patients in the US is substantial, highlighting the need for more cost-effective therapies.

    Degenerative spinal deformity afflicts a significant portion of the elderly and is increasing in prevalence. Recent evidence has revealed sagittal plane malalignment to be a key driver of pain and disability in this population and has led to a significant shift toward a more evidence-based management paradigm. In this narrative review, we review the recent literature on the epidemiology, evaluation, management, and outcomes of degenerative adult spinal deformity (ASD). ASD is increasing in prevalence in North America due to an aging population and demographic shifts. It results from cumulative degenerative changes focused in the intervertebral discs and facet joints that occur asymmetrically to produce deformity. Deformity correction focuses on restoration of global alignment, especially in the sagittal plane, and decompression of the neural elements. General realignment goals have been established, including sagittal vertical axis strategies. ASD is characterized by malalignment in the sagittal and/or coronal plane and, in adults, presents with pain and disability. Nonoperative management is recommended for patients with mild, nonprogressive symptoms; however, evidence of its efficacy is limited. Surgery aims to restore global spinal alignment, decompress neural elements, and achieve fusion with minimal complications. The surgical approach should balance the desired correction with the increased risk of more aggressive maneuvers. In well-selected patients, surgery yields excellent outcomes. PMID:26378361

    Purpose: To determine the prevalence of clinically relevant non-inflammatory disease on MRI of the sacroiliac (SI) joints in patients suspected of sacroiliitis. To assess the added value of axial imaging of the pelvis in these patients. Methods: In a retrospective study of 691 patients undergoing MRI of the SI joints from January 2006 to December 2012 for inflammatory back pain the prevalence of sacroiliitis and non-inflammatory disease was recorded. Results: In 285 (41%) patients MRI did not show any abnormal findings. In 36% of patients MRI features of sacroiliitis were present. Spinal degenerative changes were the most common non-inflammatory finding in 305 patients (44.1%) and consisted of disc degeneration in 222 (32%) patients, facet joint arthrosis in 58 (8.4%) patients and disc herniation in 25 (3.6%) patients. Hip joint disease in 44 (6.4%) patients, lumbosacral transitional anomaly in 41 (5.9%) patients, SI joint degenerative changes in 25 (3.6%) patients and diffuse idiopathic skeletal hyperostosis in 24 (3.5%) patients were also common. Osteitis condensans ilii in 17 (2.5%) patients, tumour in 11 (1.6%) patients, fracture in 8 (1.2%) patients, infection in 4 (0.6%) patients and acute spondylolysis in 2 patients (0.3%) were less frequently seen. Conclusion: Our study shows that non-inflammatory disease is more common than true sacroiliitis on MRI of the SI joints in patients with inflammatory type back pain. Axial pulse sequences may demonstrate unexpected findings that remain undetected if only coronal images are obtained. Clinical relevance statement:, MRI of the SI joints may demonstrate conditions that clinically mimic sacroiliitis. Axial imaging of the pelvis may help detect these unexpected findings.

  17. Canine degenerative myxomatous mitral valve disease: natural history, clinical presentation and therapy.

    Borgarelli, Michele; Haggstrom, Jens

    2010-07-01

    Myxomatous mitral valve disease is a common condition in geriatric dogs. Most dogs affected are clinically asymptomatic for a long time. However, about 30% of these animals present a progression to heart failure and eventually die as a consequence of the disease. Left atrial enlargement, and particularly a change in left atrial size, seems to be the most reliable predictor of progression in some studies, however further studies are needed to clarify how to recognize asymptomatic patients at higher risk of developing heart failure. According to the published data on the natural history of the disease and the results of published studies evaluating the effect of early therapy on delaying the progression of the disease, it seems that no currently available treatment delays the onset of clinical signs of congestive heart failure (CHF). Although the ideal treatment of more severely affected dogs is probably surgical mitral valve repair or mitral valve replacement, this is not a currently available option. The results of several clinical trials together with clinical experience suggest that dogs with overt CHF can be managed with acceptable quality of life for a relatively long time period with medical treatment including furosemide, an angiotensin-converting enzyme inhibitor, pimobendan, and spironolactone.

  18. Huntington disease: a single-gene degenerative disorder of the striatum

    Nopoulos, Peggy C.

    2016-01-01

    Huntington disease (HD) is an autosomal dominant, neurodegenerative disorder with a primary etiology of striatal pathology. The Huntingtin gene (HTT) has a unique feature of a DNA trinucleotide (triplet) repeat, with repeat length ranging from 10 to 35 in the normal population. Repeat lengths between 36 and 39 cause HD at reduced penetrance (some will get the disease, others won't) and when expanded to 40 or more repeats (mHTT), causes HD at full penetrance (every person with this length or beyond will definitely develop the disease). The symptoms of HD may be motor, cognitive, and psychiatric, and are consistent with the pathophysiology of frontostriatal circuitry malfunction. Expressed ubiquitously and throughout the entire life cycle (development through adulthood), mHTT causes initial dysfunction and eventual death of a specific cell population within the striatum. Although all areas of the brain are eventually affected, the primary pathology of the disease is regionally specific. As a single-gene disorder, HD has the distinction of having the potential of treatment that is aimed directly at the known pathogenic mechanism by gene silencing, providing hope for neuroprotection and ultimately, prevention.

  19. Varus deformity of the left lower extremity causing degenerative lesion of the posterior horn of the left medial meniscus in a patient with Paget’s disease of bone

    Al Kaissi, Ali

    2014-09-01

    Full Text Available [english] We report on a 42-year-old woman who presented with persistent pain in her left knee with no history of trauma. Sagittal T1-weighted MRI of the left knee showed discontinuity between the anterior and posterior horns of the left medial meniscus, causing effectively the development of degenerative lesion of the posterior horn. The latter was correlated to varus deformity of the left lower extremity associated with subsequent narrowing of the medial knee joint. The unusual craniofacial contour of the patient, the skeletal survey and the elevated serum alkaline phosphatase were compatible with the diagnosis of Paget’s disease of the bone. To alleviate the adverse effect of the mal-alignment of the left femur onto the left knee, corrective osteotomy of the left femoral diaphysis by means of fixators was performed. To the best of our knowledge this is the first clinical report describing the management and the pathological correlation of a unilateral varus deformity of the femoral shaft and degenerative lesions of the left knee in a patient with Paget’s disease of the bone.

  20. Cost effectiveness of PET and Spect in degenerative and neoplastic diseases of the brain

    In Germany the performance of emission tomographic investigations of the brain is more expensive than that of X-ray computerized tomography (CT) or magnetic resonance imaging (MRI). However, the development of emission tomogrpahy has opened a new dimension of research on brain functions and the pathogenesis of brain diseases. Furthermore, the use of this technique in patients with neurodegenerative diseases and brain tumors may yield a more accurate diagnosis than can be obtained by CT or MRI. In many instances this gain in diagnostic accuracy leads to a significant improvement of patient management. If effective therapy is available - as in the case of gliomas or akinetic-rigid syndromes - emission tomography may also prove to be cost-effective due to a reduction of the financial burden caused by inadequate therapy.

  2. Assistive technology in occupational therapy practice with a child with degenerative disease of the central nervous system

    Tácia Caroline de Lima Rodrigues

    2015-07-01

    Full Text Available This paper aims to report the effects of the interventions, using the resource of assistive technology, carried out with a child with degenerative disease of the central nervous system at his home. This is a study case, which was conducted in seven meetings, addressing the child and his caregivers during a process of evaluation, preparation of assistive devices, family orientation, and evaluation of the family environment repercussion. The results showed that the child presents significant motor, cognitive, and psychosocial impairments, resulting in difficulties in performing activities of daily living, communication, and play. Adjustments were proposed to facilitate the child’s involvement and alleviate family difficulties on equipment and environments, such as wheelchair, bedroom, bathroom, orthosis, toys and communication. Finally, it was possible to note that the assistive technology resources were used according to the child’s needs and his own reality, and that the domiciliary visits contributed positively to the family’s life because they facilitated the child’s care, despite the limitations faced.

  3. Clinical potential and limitation of MRI for degenerative lumbar spinal diseases. Comparison of MRI, myelography, CT and selective nerve root infiltration

    To assess the clinical potential and limitations of magnetic resonance imaging (MRI) in degenerative lumbar spinal diseases, the findings of MR imaging were compared with those of myelography and CT. The subjects were 80 patients with intervertebral disc herniation (46), spondylosis (28), degenerative spondylolisthesis (5), and spondylolysis (one). There was a good correlation between sagittal MRI (T1-weighted images) and myelography in measuring the anteroposterior diameter and the compression rate of the injured dural canal in all disease categories. However, MRI was inferior, irrespective of sagittal and coronal images, to myelography in detecting blocking of the dural canal and intradural findings such as redundant nerve roots. MRI was inferior to selective nerve root infiltration in visualizing the compression of the nerve root, irrespective of diseases; however, there was no difference in abnormal findings of the running of nerve root between the two modalities. Transverse MRI was superior to CT in visualizing the nerve root. Thus, MRI alone is insufficient for the diagnosis of degenerative lumbar spinal diseases, and the other modalities should be supplementary for pathophysiological understanding of these diseases.

  4. The diabetes drug liraglutide prevents degenerative processes in a mouse model of Alzheimer's disease.

    McClean, Paula L; Parthsarathy, Vadivel; Faivre, Emilie; Hölscher, Christian

    2011-04-27

    Type 2 diabetes is a risk factor for Alzheimer's disease, most likely linked to an impairment of insulin signaling in the brain. The incretin hormone glucagon-like peptide-1 (GLP-1) facilitates insulin signaling, and novel long-lasting GLP-1 analogs, such as liraglutide, are on the market as diabetes therapeutics. GLP-1 has been shown to have neuroprotective properties in vitro and in vivo. Here we tested the effects of peripherally injected liraglutide in an Alzheimer mouse model, APP(swe)/PS1(ΔE9) (APP/PS1). Liraglutide was shown to cross the blood-brain barrier in an acute study. Liraglutide was injected for 8 weeks at 25 nmol/kg body weight i.p. once daily in 7-month-old APP/PS1 and wild-type littermate controls. In APP/PS1 mice, liraglutide prevented memory impairments in object recognition and water maze tasks, and prevented synapse loss and deterioration of synaptic plasticity in the hippocampus, commonly observed in this model. Overall β-amyloid plaque count in the cortex and dense-core plaque numbers were reduced by 40-50%, while levels of soluble amyloid oligomers were reduced by 25%. The inflammation response as measured by activated microglia numbers was halved in liraglutide-treated APP/PS1 mice. Numbers of young neurons in the dentate gyrus were increased in APP/PS1 mice with treatment. Liraglutide treatment had little effect on littermate control mice, whose behavior was comparable to wild-type saline controls; however, synaptic plasticity was enhanced in the drug group. Our results show that liraglutide prevents key neurodegenerative developments found in Alzheimer's disease, suggesting that GLP-1 analogs represent a novel treatment strategy for Alzheimer's disease.

  5. Estrogen’s action on cognitive function, memory processes, neuro- degenerative diseases: A Review.

    Robel Abay

    2015-12-01

    Full Text Available Estrogen has an effect on cognitive enhancing and neuroprotection and in the incidence progress and manifestations of most of central nervous system disorders, including neurodegenerative disease. Estrogen effects on cognition depend on the cognitive task and its dependent brain regions. In hippocampus estrogen induces increased numbers of synapses on multiple synaptic boutons between neurons not previously connected. There are fundamental differences between men and women in the underlying pathophysiology, incidence, manifestation, severity, and/or progression of CNS disorders such as PD, schizophrenia, attention deficit/hyperactivity disorder, and autism.

  6. Neurochemical imaging of Alzheimer`s disease and other degenerative dementias

    Frey, K.A.; Minoshima, S.; Kuhl, D.E. [Ann Arbor, Univ. of Michigan, MI (United States). Dept. of Internal Medicine. Division of Nuclear Medicine

    1998-09-01

    A wide variety of neurochemical and functional imaging approaches have been applied to the study of progressive dementias, particularly Alzheimer`s disease (Ad) and related disorders. Despite considerable progress in the past decade, the cause(s) of most cases of Ad remain undetermined and preventive or protective therapies are lacking. Specifically-designed imaging procedures have permitted the testing of pathophysiological hypotheses of the etiology and progression of Ad, and have yielded important insights in several areas including the potential roles of cerebral cortical cholinergic lesions, cellular inflammation, and losses of cortical synapses. From the perspective of clinical diagnosis, PET glucose metabolism imaging with use of ({sup 18}F)2-fluorodeoxyglucose (FDG) is the most sensitive and specific imaging modality yet identified. The overall performance of PET FDG is favorable for routine clinical evaluation of suspected Ad, and will likely gain increasing utilization in the near future. Assessments of glucose metabolism and other, specific aspects of neurochemistry in Ad will provide direct measures of therapeutic drug actions and may permit distinction of symptomatic versus disease-modifying therapies as they are developed and introduced in clinical trials.

    The aim of this article is to describe rare and often unrecognized causes of spinal pain syndromes. Intervertebral disc degeneration frequently appears in early adulthood and can have a symptomatic or asymptomatic course. This article discusses incidence, pathophysiology, imaging, and pain symptomatology involved in the origin of back pain. Anulus tears are often found in asymptomatic individuals but could be implicated in lumbar pain symptomatology in correlation with the provocative discography. Transient disorders can lead to pseudarthrosis of the iliac bone and to degeneration or to a reactive hypermobility with intervertebral disc degeneration in the level above. Modic type 1 erosive osteochondrosis is characterized by bone marrow edema near the hyaline cartilage end plate, which mostly elicits severe pain and results in serious limitations in everyday activities. The most important differential diagnosis is spondylodiscitis. Schmorl's nodes can exhibit considerable surrounding bone marrow edema that can be mistaken for metastases. A combination of MRI and CT should be employed for the diagnostic work-up of fatigue fracture of the interarticular portion, which is often overlooked due to its location. Synovial cysts of the facet joints can lead to radicular symptoms. Insufficiency fracture of the sacrum is frequently mistaken for metastasis due to intense scintigraphic enhancement and its signal behavior in MRI. CT provides instructive information. Differential diagnosis should include less common causes such as anulus tears, transient disorders, activated Schmorl's nodes, synovial cysts of the facet joints, fatigue fractures of the interarticular portion of the spine and the sacrum and distinguish from metastases in particular. (orig.) [German] Darstellung seltener und oft verkannter Ursachen von Wirbelsaeulenschmerzsyndromen. Eine Bandscheibendegeneration tritt haeufig im fruehen Erwachsenenalter auf und kann symptomatisch oder asymptomatisch verlaufen. Diskutiert werden Inzidenz, Pathophysiologie, Bildgebung und Schmerzsymptomatik der Rueckenschmerzursachen. Anulusrisse werden haeufig bei asymptomatischen Individuen gefunden, konnten aber in Korrelation mit der provokativen Diskographie mit einer lumbalen Schmerzsymptomatik in Verbindung gebracht werden. Uebergangsstoerungen koennen zu einem Nearthros zum Os sacrum/Os ileum und zur Degeneration fuehren oder zu einer reaktiven Hypermobilitaet mit Bandscheibendegeneration in der darueber liegenden Hoehe. Die erosive Osteochondrose, Typ Modic I, zeichnet sich durch ein abschlussplattennahes Knochenmarkoedem aus, das meist starke Schmerzen hervorruft und zu starken Einschraenkungen im taeglichen Leben fuehrt. Die wichtigste Differenzialdiagnose ist die Spondylodiszitis. Schmorl-Knoten koennen ein erhebliches umgebendes Knochenmarkoedem aufweisen und mit Metastasen verwechselt werden. Zur Diagnostik der akuten Ermuedungsfraktur der Interartikularportion, die aufgrund ihrer Lage haeufig uebersehen wird, sollte eine Kombination aus MRT und CT erfolgen. Synoviale Zysten der Facettengelenke koennen zu radikulaeren Symptomen fuehren. Die Insuffizienzfraktur des Sakrums wird aufgrund einer starken szintigraphischen Anreicherung und ihres Signalverhaltens in der MRT haeufig mit einer Metastasierung verwechselt. Wegweisend ist die CT. In die Differenzialdiagnostik sollten seltenere Ursachen wie Anulusrisse, Uebergangsstoerungen, aktivierte Schmorl-Knoten, synoviale Zysten der Facettengelenke, Ermuedungsfrakturen der Interartikularportion und des Sakrums einbezogen und insbesondere zur Metastasierung abgegrenzt werden.

  8. Vegetables as a Source of Dietary Fiber to Prevent Degenerative Diseases

    Deddy Muchtadi

    2001-04-01

    Full Text Available For long time vegetables were thought only as sources of several vitamins; however, it has been shown that vegetables contain other component, which is also important for maintaining body's health, i.e., dietary fiber. Dietary fiber is a group of polysaccharides oan other polymers, which cannot be digested by upper gastro-intestinal system of human. Dietary fiber can be grouped as soluble and insoluble dietary fiber, showing in different physiological effect. Soluble dietary fiber (SDF is effective in preventing cardiovascular disease, while insoluble dietary fiber (IDF can prevent the development of colon cancer, diverticulosis as well as obesity.Local vegetables found to contain high SDF (higher than 3,06% db are: watercress, green bean, carrot, eggplant, lettuce, broccoli, spinach, string bean, and aubergine; while which contain high IDF (higher than 40,60% db are: winged bean, watercress, chinese leaves, katuk leaves, lettuce, green bean, broccoli, carrot and spinach. Cooking (i.e. boiling, steaming and pan frying decrease the IDF content of vegetables, while their SDF content is not affected by cooking treatments.

  11. Nuclear magnetic resonance in the evaluation of the disk luxation in the temporomandibular articulation conditioned for degenerative osseous changes

    Purpose: The temporomandibular dysfunction is a common pathology. It appears with many symptoms as: joint pain, mechanic disturbance, and loss of mouth motion. The Magnetic Resonance Image is the chose method to study these alterations. The purposes of this paper are to demonstrate according to sex, the distribution of temporomandibular dysfunction and to determinant the relationships between the disc dislocation and the degenerative disease of the junction. Material and Method: 215 patients were evaluated between January 1999 and August 2004. An Elscint MRI 2 Tesla machine was used with Spin-echo (T1 and T2) Fat-sat sequences, in coronal, axial and sagittal planes. The follow alterations were evaluated: dislocation, degenerative disease of articular surface, osteochondritis, discal perforation, and retrodiscal lesions. Results: 175 of all showed pathologic alterations in IRM examination. The other 40 patients were excluded due to present a normal (MRI) study. The patients were 146 females and 29 men. The most common dislocation site was the anterior. Performance of the IRM was useful in all the cases to demonstrate degenerative changes in the temporomandibular joint (TMJ). And was a very precise relationship between the dislocation and degenerative disease of the joint. Conclusion: the female patient is the most frequently affected by temporomandibular joint pathology. The IRM is the selection method to study the TMJ. The degenerative changes are responsible for joint dislocation without reduction. (author)

    The etiology of chronic diseases of the ankle joint comprises a wide spectrum including chronic inflammatory processes and chronic degenerative, tumorous and neuropathic processes, as well as some specific syndromes based on chronic changes of the ankle joint. Of the inflammatory processes, chronic juvenile arthritis (JVC) is the most common disease. However, also Reiter disease, psoriasis or chronic monoarthritid diseases such as gout, as well as granulomatous diseases (tuberculosis, sarcoidosis) and fungal infections, may affect the ankle joint in a chronic course. Chronic degenerative changes are usually secondary due to abnormal positioning of the joint constituents or repetitive trauma. Neuropathic changes, as frequently seen in the course of diabetes, present with massive osseous destruction and malposition of the articular constituents. Chronic osseous as well as cartilaginous and synovial changes are seen in hemoplici patients. Chronic traumatic changes are represented by pigmented villonodular synovitis (PVNS), and chondromatosis, both with a predilection for the ankle joint. Due to the possibilities of magnetic resonance imaging (MRI), diagnosis of chronic ankle changes includes chronic ligamentous, tendinous and soft tissue changes. With the use MRI, specific syndromes can be defined which particularly affect the ankle joint in a chronic way, such as the os trigonum syndrome, the anterolateral impingement syndrome and the sinus tarsi syndrome. Nevertheless, plain film radiographs are still the basic element of any investigation. MRI, however, can be potentially used as a second investigation, saving an unnecessary cascade of investigations with ultrasound and CT. The latter investigations are used only with very specific indications, for instance CT for subtle bone structures and sonography for a limited investigation of tendons or evaluation of fluid. Particularly due to the possibilities of MRI and the development of special gradient-echo imaging or high-resolution coils, the investigation of the ankle joint still offers a wide spectrum of innovation for the next years, which is particularly enforced by the increasing demand for specific diagnosis of chronic diseases in orthopedic medicine. (orig.) [Deutsch] Die Aetiologie chronischer Krankheitsbilder am Sprunggelenk ist vielfaeltig. Chronisch entzuendliche Veraenderungen, wie sie im Rahmen einer chronisch juvenilen Arthritis, des M. Reiter, der Psoriasis oder chronischer Monoarthritiden, wie der chronischen Gicht zu beobachten sind, haben nicht selten ihre Manifestation am Sprunggelenk. Seltenere entzuendlich chronische Affektionen hingegen koennen jedoch auch bei enteropathischen Arthritiden, granulomatoesen Erkrankungen, wie der Tuberkulose oder Sarkoidose, beobachtet werden. Auch chronisch verlaufende Pilzaffektionen koennen zu atypischen Bildern fuehren. Chronisch degenerative Erkrankungen entstehen am Sprunggelenk fast ausschliesslich sekundaer. Praedisponierend sind hier angeborene oder erworbene Fehlhaltungen sowie chronische Veraenderungen auf Basis abgelaufener oder repetitiver Traumen. Der neuropathische Formenkreis stellt eine weitere Causa chronischer Veraenderungen dar, mit im fortgeschrittenem Stadium massiven Gelenks- und ossaeren Veraenderungen. Chronische Veraenderungen sind auch bei der Haemophilie im Rahmen des Blutergelenkes zu erwarten. Als chronisch tumoroese Veraenderungen koennen die pigmentierte villonodulaere Synovitis (PVNS) und die Gelenkschondromatose betrachtet werden, mit teils ossaeren und teils charakteristischen Kapsel und Weichteilveraenderungen. Die modernen Gelenkdiagnostik umfasst zudem auch chronische Veraenderungen an den Sehnen und Baendern. Besondere diagnostische Herausforderungen stellen letztendlich Syndrome dar, die klinisch zwar beobachtet, jedoch erst durch moderne Bildgebung in den letzten Jahren zunehmend spezifiert werden konnten. Diese umfassen zum Beispiel das `Os-trigonum-Syndrom`, das `anterolaterale Weichteilimpingement` und das `Sinus-tarsi-Syndrom`. Wie in der allgmeinen Gelenkdiagnostik ist auch weiterhin das Nativbild als Basisuntersuchung unerlaesslich. Der Einsatz der Magnetresonanztomographie (MRT) als Zweituntersuchung erspart oft eine kostenintensive und belastende Untersuchungskaskade. Der Einsatz moderner Sequenzen oder gezielte Kontrastmittelgabe erlauben zunehmend spezifische Diagnosen. Der Einsatz der Sonographie und ebenso der CT muss gezielt durchgefuehrt werden. Die Vielfalt der moeglichen chronisch pathologischen Veraenderungen und dem gegenueberstehend die Vielfalt der Untersuchungsmethoden, im speziellen der MRT-Techniken, zusammen mit den komplexen anatomischen Verhaeltnissen am Sprunggelenk stellen eine besondere Herausforderung an den Radiologen dar.

  14. Application of stable isotopic techniques in the prevention of degenerative diseases like obesity and NIDDM in developing societies

    Economic development in developing societies characterized by industrialization, urbanization and globalization has seen the emergence of an epidemic of diet and life-style related chronic degenerative diseases. A research project has been initiated under the aegis of the International Atomic Energy Agency (IAEA), Vienna, Austria, under its Co-ordinated Research Programme (CRP) to promote the use of stable isotopic techniques to document the extent of the problem and to understand the determinants of this epidemic. The principal objectives of this CRP involving countries both in the North and the South are to define the magnitude of the problem of obesity and non-insulin Dependent diabetes mellitus (NIDDM) in developing countries, to identify the vulnerable groups at increased risk and to attempt to describe the metabolic and physiological mechanisms underlying this phenomenon. These comparative international studies of obesity and NIDDM are looking at the effects of childhood malnutrition (Brazil and socio-economic differentials (Mexico) on adult risk factors; the composition of the daily diet on obesity (Chile); levels of patterns of physical activity of older adults (China) as well as their influence on weight gain and obesity (Cuba, Nigeria); the impact of body composition and energy expenditure on the evolution frank diabetes from impaired glucose tolerance (Jamaica), and of body compositional changes and the role of inflammatory cytokines on impaired glucose tolerance (India). The last study conducted in New Zealand was aimed at comparing the energy expenditures of Maori (Pacific Island) with New Zealanders of European descent. The findings of the CRP of the MEA in this area carried out in several countries are presented in this article. (author)

    Background Degenerative disc disease is a common cause of chronic and disabling back pain that requires surgical intervention, posterolateral and posterior instrumental fixation (PLF), posterior lumber interbody fusion (PLIF) and transforaminal lumber interbody fusion (TLIF) are the techniques used to deal with such a problem. Objective To compare the clinical and radiological outcome of the variable surgical techniques used to deal with Lumber degenerative disc disease and to recommend the t...

  16. Degenerative changes of the skeleton

    Degeneration of the articular cartilage induces subchondral bone remodelling, which can be recognized in the bone scan by an enhanced radionuclide uptake. It cannot be distinguished from radionuclide uptake caused by other bony lesions. Thus the scintigraphic diagnosis of degenerative bone disease bases essentially on the consideration of its sites of predilection and on the exclusion of inflammation by three-phase bone scans. Due to the higher spatial resolution compared to planar imaging, SPECT is preferably used in the detection of degenerative changes of the vertebral column. As radionuclide uptake is enhanced already in the early stage of degenerative changes and only in sites of active disease but not in old, healed lesions, SPECT-imaging can make a contribution to the differential diagnosis of back pain.

    Alzheimer's disease (AD) is a neurodegenerative disease concomitant with grey and white matter damages. However, the interrelationship of volumetric changes between grey and white matter remains poorly understood in AD. Using joint independent component analysis, this study identified joint grey and white matter volume reductions based on structural magnetic resonance imaging data to construct the covariant networks in twelve AD patients and fourteen normal controls (NC). We found that three ...

    This study compared the clinical and radiological outcomes of dynamic cervical implant (DCI; Scient'x, Villers-Bretonneux, France) arthroplasty versus anterior cervical discectomy and fusion (ACDF) for the treatment of cervical degenerative disc disease. This prospective cohort study enrolled patients with single-level cervical degenerative disc disease who underwent DCI arthroplasty or ACDF between September 2009 and June 2011. Patients were followed up for more than 2years. Clinical evaluation included the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), Neck Disability Index (NDI), Japan Orthopedic Association (JOA) score, and visual analog scale (VAS) scores for neck and arm pain. Radiological assessments included segmental range of motion (ROM), overall ROM (C2-C7), disc height (DHI), and changes in adjacent disc spaces. The VAS, SF-36, JOA, and NDI scores improved significantly after surgery in both the DCI and ACDF groups. The VAS, JOA, and SF-36 scores were not significantly different between the DCI and ACDF groups at the final follow-up. The segmental ROM at the treated level and overall ROM increased significantly after surgery in the DCI group, but the ROM in the adjacent cephalad and caudal segments did not change significantly. The mean DHI at the treated level was significantly restored after surgery in both groups. Five patients (12.8%) in the DCI group showed new signs of adjacent segment degeneration. These results indicate that DCI is an effective, reliable, and safe procedure for the treatment of cervical degenerative disc disease. However, there is no definitive evidence that DCI arthroplasty has better intermediate-term results than ACDF. PMID:24411326

  1. Scintigraphy in evaluating avascular joint disease and joint prostheses

    Interruption of blood flow to the femoral head may occur as a result of trauma, medications, underlying small vessel disease or as an idiopathic process of unclear etiology. Tetracycline fluorescence of bone tissue specimens is a well-established method of determining relative bone blood flow but is poorly suited as a noninvasive or preoperative procedure. sup(99m)Tc sulfur colloid has also been used to demonstrate femoral head reticuloendothelial elements and thereby indirectly establish the presence or absence of blood supply, however, this method lacks specificity. It has been documented that 18F and, to a great extent, sup(99m)Tc phosphate compounds localize in bone as a direct function of bone blood flow. Since the radiation dose associated with sup(99m)Tc phosphates is modest and excellent images with fine detail can be obtained using the Anger camera and pinhole collimator, this technique has become the method of choice for noninvasive evaluation of vascularity of the femoral head. Specific clinical applications are presented in this chapter. (Auth.)

  2. New aspects of radionuclide therapy of bone and joint diseases

    Whereas in developing countries P-32 is widely used for radionuclide therapy of painful bone metastases, in Europe three radionuclides or radiopharmaceutical agents are available for pain palliation: Sr-89, Sm-153-EDTMP, and Re-186-HEDP. Radionuclide therapy for pain palliation is indicated for bone pain due to metastatic malignancy that has involved multiple skeletal sites and has evoked an osteoblastic response on bone scintigraphy. Response rates of about 70-80% in patients with breast or prostate cancer is reported in the literature, less in metastatic lesions of other primary malignancies. Sm-153-EDTMP may also be used for curative treatment of primary bone tumours or their metastases. Radiosynovectomy as therapeutic procedure or rheumatoid arthritis, other inflammatory joint diseases, persistent synovial perfusion, and other joint diseases is widely used. Using Y-90 for the knee joint, Re-186 for middle sized joints, and Er-169 for small joints an improvement of symptoms may be observed in about 70-80%. (author)

  3. Guidelines for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 6: magnetic resonance imaging and discography for patient selection for lumbar fusion.

    Discography is an exquisitely sensitive but not specific diagnostic test for the diagnosis of discogenic low-back pain. The restriction of the definition of a positive discographic study to one that elicits concordant pain from a morphologically abnormal disc improves the definition's accuracy. Fusion surgery based on discography alone, however, is not reliably associated with clinical success. Therefore, discography is not recommended as a standalone test for treatment decisions in patients with low-back pain. Magnetic resonance imaging is a sensitive and noninvasive test for the presence of degenerative disc disease. Discography should not be attempted in patients with normal lumbar MR images. Discography appears to have a role in the evaluation of patients with low-back pain, but it is best limited to the evaluation of abnormal interspaces identified on MR imaging, the investigation of adjacent-level disc disease, and as a means to rule out cases of nonorganic pain from surgical consideration.

  5. Computed tomography for diseases of the knee joint

    CT was performed on 126 knee joints of 63 patients with diseases of the knee joint, and the results were discussed. CT was useful to know changes in the patella, because CT images of the patella-femoral joint could visualize the position of the joint minutely and the congruence angle of the joint could be measured on CT images taken at extension position. CT images of diseases with rupture of cartilage such as steroid arthritis could visualize the rupture as the defect. Therefore, CT was useful for the following invasive therapy. In osteoarthritis of the knee joint, the progress of osteosclerosis could be observed by measuring subcartilaginous trabeculae on sequential CT images. Transaxial image of meniscus injuries by CT could visualize the meniscus. Clear CT image of crucial ligament could be obtained by air injection quadricepts femoris atrophy could be observed quantitatively by CT and furthermore CT could clearly visualize folds of synovial membrane within the patella. CT made it possible to make a diagnosis of knee joint disorders. (Tsunoda, M.)

    The clinical benefits and complications of posterior lumbar interbody fusion (PLIF) have been studied over the past 60 years. In recent years, spine surgeons have had the option of treating low back pain caused by degenerative disc disease using PLIF with machined allograft spacers and posterior pedicle fixation. The purpose of this clinical series was to assess the clinical benefits of using a machined PLIF allograft spacer and posterior pedicle fixation to treat degenerative disc disease, both in terms of fusion rates and patient outcomes, and to compare these results with those in previous studies using autograft and metal interbody fusion devices. Results were also compared with results from studies using transverse process fusion. This prospective, nonrandomized clinical series was conducted at 10 US medical centers. Eighty-nine (55 male, 34 female) patients underwent PLIF with a presized, machined allograft spacer and posterior pedicle fixation between January 2000 and April 2003. Their outcomes were compared with outcomes in previous series described in the literature. All patients had experienced at least 6 months of low back pain that had been unresponsive to nonsurgical treatment. Physical examinations were performed before surgery, after surgery, and at 4 follow-up visits (6 weeks, 6 months, 12 months, 24 months). At each interval, we obtained radiographs and patient outcome measures, including SF-36 Bodily Pain Score, visual analog scale pain rating, and Oswestry Disability Index. The primary outcome was fusion results at 12 and 24 months; the secondary outcomes were pain, disability, function/quality of life, and satisfaction. One-level PLIFs were performed in 65 patients, and 2-level PLIFs in 24 patients. Flexion-extension radiographs at 12 and 24 months revealed a 98% fusion rate. Of the 72 patients who reached the 12-month follow-up, 86% reported decreased pain and disability as measured with the Oswestry Disability Index. Decreased pain as measured with the SF-36 Bodily Pain Score was reported by 74% of patients who reached the 12-month follow-up. The graft-related complication rate among all patients who underwent PLIF was 1.61%. When performed with machined allograft spacers and posterior pedicle fixation, PLIF is a safe and effective surgical treatment for low back pain caused by degenerative disc disease. The patients in this clinical series had outcomes equal or superior to the outcomes in previous series. PMID:19714280

    Full Text Available Objective To compare the postoperative muscle damage after either posterior lumbar interbody fusion (PLIF or minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF with the aid of X-Tube system in patients with singlelevel degenerative lumbar spinal disease. Methods The clinical data of 52 patients (males 28, females 24, aged 54.3±7.8 years with single-level degenerative lumbar spinal disease undergoing MIS-TLIF assisted by the X-Tube system from Oct 2010 to Sep 2011 was analyzed retrospectively. The operative time, intraoperative blood loss, postoperative drainage volume, postoperative bedtime, and serum creatine kinase (CK level 1 day before surgery and 1, 3 and 5 days after surgery were recorded and compared with those of 38 patients (males 20, females 18, aged 51.6±8.6 years with the same disease undergoing conventional open PLIF during the corresponding period. The back pain visual analogue score (VAS, Oswestry disability index (ODI score and imaging examination were performed before operation, after operation and during follow-up duration for each patient. Results There was no significant difference in the gender, age, clinical diagnosis, lesion location, preoperative CK level, VAS and ODI scores between the two groups (P>0.05. The operative time was longer in MIS-TLIF group than in PLIF group (P0.05. Radiological followup observation revealed good fusion 6 months after operation in all the patients. Conclusion The X-Tube-assisted MIS-TLIF has several advantages over conventional open PLIF, such as less intraoperative blood loss, milder muscle damage, and lighter back pain.

    Sex differences in pain perception are known to exist; however, the exact pathomechanism remains unclear. This work aims to elucidate sex differences in subjective and objective measures of pain, functional impairment, and health-related quality of life (HRQoL) in patients with lumbar degenerative disc disease. In a prospective 2-center study, back and leg pain (visual analogue scale [VAS]), functional disability (Oswestry Disability Index and Roland-Morris Disability Index), and HRQoL (EuroQol-5D and Short Form [SF12]) were collected for consecutive patients undergoing lumbar spine surgery. Objective functional impairment (OFI) was estimated using age-adjusted and sex-adjusted cutoff values for the timed-up-and-go (TUG) test. A healthy cohort of n = 110 subjects served as the control group. Univariate and multivariate analyses were performed to test the association between sex and pain, subjective and OFIs, and HRQoL. The study comprised n = 305 patients (41.6% females). Female patients had more VAS back pain (P = 0.002) and leg pain (P = 0.014). They were more likely to report higher functional impairment in terms of Oswestry Disability Index (P = 0.005). Similarly, HRQoL measured with the EuroQol-5D index (P = 0.012) and SF12 physical composite score (P = 0.005) was lower in female patients. Female patients reported higher VAS back and leg pain, functional impairment, and reduced HRQoL than male patients. However, there were no sex differences with respect to the presence and degree of OFI measured by the TUG test using age-adjusted and sex-adjusted cutoff values. As such, the TUG may be a good test to overcome sex bias for the clinical assessment of patients with degenerative disc disease. PMID:26761383

    Full Text Available Temporomandibular disorder (TMD is an inclusive term in which those conditions disturbing the masticatory function are embraced. It has been estimated that 33% of the population have signs of TMD, but less than 5% of the population will require treatment. The objective of this study was to measure the frequency of TMD in rheumatoid arthritis (RA, osteoarthrosis (OA, ankylosing spondylitis (AS and systemic lupus erythematosus, and to define the limitations in everyday’s life that patients perceive when present. A six-month survey of consecutive outpatients in a rheumatology clinic in a teaching hospital in Mexico was carried out. We defined TMD as: 1 the presence of pain; 2 difficulty on mouth opening, chewing or speaking; 3 the presence of non-harmonic movements of the temporomaxilar joints. All three characteristics had to be present. Z test was used to define differences between proportions. We present the results of 171 patients. Overall, 50 patients had TMD according to our operational definition (29.24%. Up to 76% of the sample had symptoms associated with the condition. TMD is more frequent in OA and in AS (29.24% vs 38% OA, P=0.009; 39% AS; P=0.005. We found no association between the severity of TMD and the request for specific attention for the discomfort produced by the condition. Only 8 of 50 (16% patients with TMD had requested medical help for their symptoms, and they were not the most severe cases. TMD is more frequent in RA and OA. Although it may produce severe impairment, patients seem to adapt easily.

    2015-08-01

    Full Text Available David Ip, Nga Yue FuAsia Medical Pain Centre, Grand Plaza, Mong Kok, Hong KongBackground: This study evaluated whether half-yearly hyaluronic acid injection together with low-level laser therapy in addition to standard conventional physical therapy can successfully postpone the need for joint replacement surgery in elderly patients with bilateral symptomatic tricompartmental knee arthritis.Methods: In this prospective, double-blind, placebo-controlled study, 70 consecutive unselected elderly patients with bilateral tricompartmental knee arthritis were assigned at random to either one of two conservative treatment protocols to either one of the painful knees. Protocol A consisted of conventional physical therapy plus a sham light source plus saline injection, and protocol B consisted of protocol A with addition of half-yearly hyaluronic acid injection as well as low-level laser treatment instead of using saline and a sham light source. Treatment failure was defined as breakthrough pain necessitating joint replacement.Results: Among the 140 painful knees treated with either protocol A or protocol B, only one of the 70 painful knees treated by protocol B required joint replacement, whereas 15 of the 70 painful knees treated by protocol A needed joint replacement surgery (P<0.05.Conclusion: We conclude that half-yearly hyaluronic acid injections together with low-level laser therapy should be incorporated into the standard conservative treatment protocol for symptomatic knee arthritis, because it may prolong the longevity of the knee joint without the need for joint replacement.Keywords: knee osteoarthritis, hyaluronic acid injection, low-level laser, outcome

    This paper reviews hypotheses about roles of angiogenesis in the pathogenesis of inflammatory disease in two organs, the synovial joint and the lung. Neovascularisation is a fundamental process for growth and tissue repair after injury. Nevertheless, it may contribute to a variety of chronic inflammatory diseases, including rheumatoid arthritis, osteoarthritis, asthma, and pulmonary fibrosis. Inflammation can promote angiogenesis, and new vessels may enhance tissue inflammation. Angiogenesis ...

    Study Design A multinational, multiethnic, cross-sectional image-based study was performed in 33 institutions, representing 10 countries, which were part of the AOSpine Asia Pacific Research Collaboration Consortium. Objective Lumbar facet joint orientation has been reported to be associated with the development of degenerative spondylolisthesis (DS). The role of ethnicity regarding facet joint orientation remains uncertain. As such, the following study was performed across a wide-ranging population base to assess the role of ethnicity in facet joint orientation in patients with DS in the Asia Pacific region. Methods Lateral standing X-rays and axial magnetic resonance imaging scans were obtained for patients with lumbar DS. The DS parameters and facet joint angulations were assessed from L3–S1. Sex, age, body mass index (BMI), and ethnicity were also noted. Results The study included 371 patients with known ethnic origin (mean age: 62.0 years; 64% males, 36% females). The mean BMI was 25.6 kg/m2. The level of DS was most prevalent at L4–L5 (74.7%). There were 28.8% Indian, 28.6% Japanese, 18.1% Chinese, 8.6% Korean, 6.5% Thai, 4.9% Caucasian, 2.7% Filipino, and 1.9% Malay patients. Variations in facet joint angulations were noted from L3 to S1 and between patients with and without DS (p  0.05); however, increasing age was found to increase the degree of angulation throughout the lumbar spine (p  0.05). Ethnic variations were noted in non-DS L5–S1 facet joint angulations, predominantly between Caucasian, Chinese, and Indian ethnicities (p < 0.05). Conclusions This study is the first to suggest that ethnicity may not play a role in facet joint orientation in the majority of cases of DS in the Asia-Pacific region. Findings from this study may facilitate future comparative studies in other multiethnic populations. An understanding of ethnic variability may assist in identifying those patients at risk of postsurgical development or progression of DS. This study also serves as a model for large-scale multicenter studies across different ethnic groups and cultural boundaries in Asia. PMID:26835200

  17. TRPV4 as a therapeutic target for joint diseases.

    McNulty, Amy L; Leddy, Holly A; Liedtke, Wolfgang; Guilak, Farshid

    2015-04-01

    Biomechanical factors play a critical role in regulating the physiology as well as the pathology of multiple joint tissues and have been implicated in the pathogenesis of osteoarthritis. Therefore, the mechanisms by which cells sense and respond to mechanical signals may provide novel targets for the development of disease-modifying osteoarthritis drugs (DMOADs). Transient receptor potential vanilloid 4 (TRPV4) is a Ca(2+)-permeable cation channel that serves as a sensor of mechanical or osmotic signals in several musculoskeletal tissues, including cartilage, bone, and synovium. The importance of TRPV4 in joint homeostasis is apparent in patients harboring TRPV4 mutations, which result in the development of a spectrum of skeletal dysplasias and arthropathies. In addition, the genetic knockout of Trpv4 results in the development of osteoarthritis and decreased osteoclast function. In engineered cartilage replacements, chemical activation of TRPV4 can reproduce many of the anabolic effects of mechanical loading to accelerate tissue growth and regeneration. Overall, TRPV4 plays a key role in transducing mechanical, pain, and inflammatory signals within joint tissues and thus is an attractive therapeutic target to modulate the effects of joint diseases. In pathological conditions in the joint, when the delicate balance of TRPV4 activity is altered, a variety of different tools could be utilized to directly or indirectly target TRPV4 activity.

  18. Temporomandibular joint MR imaging

    MR imaging has been used in the temporomandibular joint (TM) for identifying the position of the disk. This report examines the significance of altered morphology and signal characteristics of the TMJ disk as they relate to the severity of the internal derangement. MR was used to examine 216 joints in 133 patients. Disk position, signal, morphology and the presence of degenerative joint disease (DJD) were determined for each joint. The duration of symptoms, severity of pain, joint noise, and restriction to opening were graded. Abnormal disk morphology and decreased disk signal had a high association with joint DJD and duration of symptoms. This grading system appears to correlate with the severity of the internal derangement

  19. Calidad de vida relacionada con la salud en personas con enfermedades crónicas degenerativas Quality of life related to health in persons with chronic degenerative diseases

    2008-12-01

    Full Text Available INTRODUCCIÓN. La calidad de vida relacionada con la salud es un indicador que incorpora la apreciación del individuo sobre su enfermedad. En la revisión bibliográfica se encontró que en Cuba no hay experiencia en el uso del WHOQOL _ BREF como instrumento de medición de esta, por lo que se pretende describirlo en personas que presentan enfermedades crónicas degenerativas, para determinar si es aplicable en el contexto cubano. MÉTODOS. Estudio descriptivo de calidad de vida relacionada con la salud en 300 personas con enfermedades crónicas degenerativas que están entre las tres primeras causas de mortalidad en el país. Se aplicaron encuestas con el instrumento WHOQOL _ BREF. RESULTADOS. Fueron contestadas el 100 % de las encuestas. El porcentaje se desglosó como sigue: 51,3 de los enfermos consideraron su calidad de vida relacionada con la salud "ni pobre ni buena" y 33,3 como "buena". 48,6 se valoró "ni satisfecho ni insatisfecho" y 33,3 "satisfecho". La salud psicológica fue calificada "alta" en los tres tipos de enfermedades y el dominio que explora ambiente recibió la calificación de "regular." Las mujeres, en ambos grupos de edades, la consideraron "aceptable". Por tipo de enfermedad, las de 45 y más años, que padecían un tumor, tenían una "alta" calidad de vida relacionada con la salud. CONCLUSIONES. El WHOQOL _ BREF permitió medir correctamente la calidad de vida relacionada con la salud en personas con enfermedades crónicas degenerativas, lo que supone que es aplicable al contexto cubano. La salud psicológica resultó la mejor valorada en cualesquiera de las enfermedades estudiadas.INTRODUCTION: The quality of life related to health is an indicator that incorporates the individual's appreciation of his illness. In the bibliographical review it was found that in Cuba there is no experience in the use of the WHOQOL_BREF as an instrument to measure it. That's why, it is intended to describe it in persons with chronic degenerative illness to determine if it can be applied to the Cuban context. METHODS: A descriptive study of the quality of life connected with health was conducted in 300 individuals with chronic degenerative diseases that are among the first three causes of death in the country. Surveys were done with the WHOQOL_BREF instrument. RESULTS: 100% of the surveys were answered. 51.3% of the sick persons considered its quality of life in relation to health neither poor nor good and 33.3% considered it good. 48.6 % evaluated themselves as neither satisfied nor unsatisfied and 33.3 % as satisfied. The psychological health was rated as "high" in the three types of diseases, whereas the domain exploring environment was estimated as fair. Females, in both groups of ages, considered it "acceptable." According to the type of disease, those aged 45 and over suffering from a tumor had a high quality of life related to health. CONCLUSIONS: The WHOQOL_BREF allowed to measure correctly the quality of life related to health in people with chronic degenerative diseases, which makes us suppose that it is applicable to the Cuban context. The psychological health was the best assessed in any of the studied diseases

  1. [Musculoskeletal pathology in occupational risks and common degenerative disease: reflections on the intensity and duration of the risk].

    Bergamini, Roberta; Astengo, Rossana

    2014-01-01

    Nowadays, in Italy the reports of mnusculoskeletal diseases increase as confirmed in the last INAIL (national insurance for occupational diseases and injuries) annual report. The Emilia-Ronmagna is one of the region with the highest number of reports: 15.9% of the total in 2012. The decree no. 81/08 has partially simplified the medico-legal activities related to musculoskeletal diseases; however, the medico-legal physicians have still to deal with some issues such as risk assessment quality, economic crisis, and specific work environments (e.g. agriculture and many handicraft activities). Tire risk factors of musculoskeletal diseases and their assessments are quite well studied. The latency period of these diseases needs to be investigated, since it could be a relevant aspect for legal medical judgment, insurance protection and prevention. Based on literature data and INAIL experience, authors propose some considerations useful for a scientific debate. PMID:25558730

  2. Biomechanics of Degenerative Spinal Disorders

    Iorio, Justin A.; Jakoi, Andre M.

    2016-01-01

    The spine has several important functions including load transmission, permission of limited motion, and protection of the spinal cord. The vertebrae form functional spinal units, which represent the smallest segment that has characteristics of the entire spinal column. Discs and paired facet joints within each functional unit form a three-joint complex between which loads are transmitted. Surrounding the spinal motion segment are ligaments, composed of elastin and collagen, and joint capsules which restrict motion to within normal limits. Ligaments have variable strengths and act via different lever arm lengths to contribute to spinal stability. As a consequence of the longer moment arm from the spinous process to the instantaneous axis of rotation, inherently weaker ligaments (interspinous and supraspinous) are able to provide resistance to excessive flexion. Degenerative processes of the spine are a normal result of aging and occur on a spectrum. During the second decade of life, the intervertebral disc demonstrates histologic evidence of nucleus pulposus degradation caused by reduced end plate blood supply. As disc height decreases, the functional unit is capable of an increased range of axial rotation which subjects the posterior facet capsules to greater mechanical loads. A concurrent change in load transmission across the end plates and translation of the instantaneous axis of rotation further increase the degenerative processes at adjacent structures. The behavior of the functional unit is impacted by these processes and is reflected by changes in the stress-strain relationship. Back pain and other clinical symptoms may occur as a result of the biomechanical alterations of degeneration. PMID:27114783

  3. Co-ordinated research project on application of nuclear techniques in the prevention of degenerative diseases (obesity and non-insulin dependent diabetes) in ageing

    In the developed countries, research using nuclear methods has been substantially used to examine the physiological and biochemical mechanisms involved in obesity-related diseases. This Co-ordinated Research Project (CRP) is intended to promote the use of these techniques in the developing world. The specific objectives of this CRP are: 1. To define the magnitude of the obesity/NIDDM problem in developing countries. 2. To identify vulnerable groups at high risk. 3. To describe the metabolic mechanisms involved. The purpose of this first Research Co-ordination Meeting (RCM) was thus to develop a worldwide collaboration in the use of nuclear and isotopic techniques to investigate the aetiology of degenerative diseases in ageing. All countries participating in this CRP are going through the epidemiological transition with changes in lifestyles to approach those seen in the developed nations. This first meeting was held in the Agency's headquarters in Vienna, with participation of contract and agreement holders, experts, observer, and in-house staff

  4. Studies on the pathogenesis of the degenerative lumbar canal stenosis by CT, 3

    Computed tomography (CT) scans of lumbar canal stenosis (LCS, n = 20), osteoarthritis (OA, n = 65), disk herniation (n = 21), and lumbar pain (n = 23) were reviewed for the quanlitative evaluation of the vertebral canal and stenosis factors. Trefoil type on transverse sections of the bony vertebral canal was observed in 23 %, having no implications for pathologic significance at the L5 level. The degree of degeneration in soft tissues inside the vertebral canal varied according to diseases. This was most noticeable at the L4/L5 level in the LCS group. The morphological CT appearance of vertebral arch were divided into three types: I - the concave inner part, II - the linear inner part, and III - the convex inner part to the vertebral canal. In the group of LCS, the incidences of types II and III were high at the L5/S1 and at the L4/L5 levels, respectively. As for the angle of apophyseal joint, the incidence of sagittal joint was high at the L3/L4 and L4/L5 levels in the group of LCS. The incidence of degenerative changes was high in the groups of LCS and OA, suggesting some relationship between degenerative degree and both sagittal and asymmetric joints. This was noticeable at the L4/L5 level. Calcification surrounding the joint was seen in 13 %, reflecting the relationship to the degenerative changes. There was no relationship between degenerative changes and vacuum joint phenomenon observed in 18 %. As for the area less than 90 mm2 of the dural canal, there was no morphological change between the LCS and OA groups. In the symptomatic mechanism in the case of LCS, morphological dynamic and unstable factors may be involved. (Namekawa, K.) 67 refs

(Rumania can be recommended for wide administration in treatment of joint diseases particularly in pts with concomitant gastrointestinal diseases and hypertension.

  7. Non-invasive investigation in patients with inflammatory joint disease

    Full Text Available Gut inflammation can occur in 30%-60% of patients with spondyloarthropathies. However, the presence of such gut inflammation is underestimated, only 27% of patients with histological evidence of gut inflammation have intestinal symptoms, but subclinical gut inflammation is documented in two-thirds of patients with inflammatory joint disease. There are common genetic and immunological mechanisms behind concomitant inflammation in the joints and intestinal tract. A number of blood tests, e.g. erythrocyte sedimentation rate, orosomucoid, C-reactive protein, and white cell and platelet counts, are probably the most commonly used laboratory markers of inflammatory disease, however, these tests are difficult to interpret in arthropathies associated with gut inflammation, since any increases in their blood levels might be attributable to either the joint disease or to gut inflammation. Consequently, it would be useful to have a marker capable of separately identifying gut inflammation. Fecal proteins, which are indirect markers of neutrophil migration in the gut wall, and intestinal permeability, seem to be ideal for monitoring intestinal inflammation: they are easy to measure non-invasively and are specific for intestinal disease in the absence of gastrointestinal infections. Alongside the traditional markers for characterizing intestinal inflammation, there are also antibodies, in all probability generated by the immune response to microbial antigens and auto-antigens, which have proved useful in establishing the diagnosis and assessing the severity of the condition, as well as the prognosis and the risk of complications. In short, non-invasive investigations on the gut in patients with rheumatic disease may be useful in clinical practice for a preliminary assessment of patients with suspected intestinal disease.

  8. Could astrocytes be the primary target of an offending agent causing the primary degenerative diseases of the human central nervous system? A hypothesis.

    Sica, Roberto E

    2015-05-01

    Most of the named primary degenerative diseases of the human central nervous system have been attributed to a direct, primary damage of some particular population of neurons. Within the spectrum of these illnesses there are disorders like amyotrophic lateral sclerosis, fronto-temporal dementia, Alzheimer's dementia, Parkinson's disease, Huntington's dementia and cerebellar ataxias affecting exclusively the human species. In the last years it has been shown that non-neural cells, mainly astrocytes, have a crucial role in the starting and development of these diseases. We suggest that the causative agent of these illnesses gets home first within the astrocytes, rather than the neurons, making them sick by modifying the structure of some proteins; from these cells the abnormal process would start a trip to other astrocytes having the same genetic, metabolic, structural and functional profiles that the originally affected astrocytes have, going through the gap junctions which connect that particular population devoted to a particular set of neurons. This appears to be a likely hypothesis because the astrocytes related to a defined population of neurons have their own, private properties and characteristics needed to support one particular set of neurons performing a defined function, making them a different and unique population, a fact which would limit the spreading of the disease to those astrocytes, sparing other astrocyte populations which do not share those characteristics. If this were the mechanism underlying these illnesses, the neurons, which their health depends on those astrocytes, would be deprived of their patronage and would start all the changes that characterizes a programmed cell death, and the clinical manifestations of a defined pathology would consequently appear.

  9. Degenerative diseases of the cervical spine: comparison of a multiecho data image combination sequence with a magnetisation transfer saturation pulse and cervical myelography and CT

    Assessing degenerative disease in the cervical spine remains a challenge. There is much controversy about imaging the cervical spine using MRI. Our aim in this prospective study was to compare a T2*-weighted 2D spoiled gradient-echo multiecho sequence (MEDIC) with a magnetisation transfer saturation pulse with cervical myelography and postmyelographic CT. Using an assessment scale we looked at the vertebral bodies, intervertebral discs, neural foramina, anterior and posterior nerve roots, grey matter, ligamenta flava, oedema in the spinal cord and stenosis of the spinal canal. We also evaluated postmyelography CT and the MEDIC sequence for assessing narrowing of the neural foramina in a cadaver cervical spine. We examined 67 disc levels in 18 patients, showing 18 disc prolapses and 21 osteophytes narrowing the spinal canal or the neural foramina. All MRI studies showed these abnormalities findings equally well. Postmyelography CT was significantly better for showing the bony structures and the anterior and posterior nerve roots. The MEDIC sequence provided excellent demonstration of soft-tissue structures such as the intervertebral disc and ligamentum flavum. No statistical differences between the imaging modalities were found in the assessment of narrowing of the neural foramina or the extent of spinal stenosis. The cadaver measurements showed no overestimation of abnormalities using the MEDIC sequence. (orig.)

  10. Guidelines for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 15: electrophysiological monitoring and lumbar fusion.

    Based on the medical evidence provided by the literature reviewed, there does not appear to be support for the hypothesis that any form of intraoperative monitoring improves patient outcomes following lumbar decompression or fusion procedures for degenerative spinal disease. Evidence does indicate that a normal evoked EMG response is predictive for intrapedicular screw placement (high NPV for breakout). The presence of an abnormal EMG response does not, however, exclude intrapedicular screw placement (low PPV). The majority of clinically apparent postoperative nerve injuries are associated with intraoperative changes in SSEP and/or DSEP monitoring. For this reason, changes in DSEP/SSEP monitoring appear to be sensitive to nerve root injury. There is a high-false positive rate, however, and changes in DSEP and SSEP recordings are frequently not related to nerve injury. A normal study has been shown to correlate with the lack of a significant postoperative nerve injury. There is no substantial evidence to indicate that the use of intraoperative monitoring of any kind provides useful information to the surgeon in terms of assessing the adequacy of nerve root decompression at the time of surgery.

    Full Text Available Objective: This pilot study was designed to describe changes in spiritual well-being (SWB, spiritual coping, and quality of life (QOL in patients with brain cancer or other neurodegenerative diseases participating in a chaplain-led spiritual life review interview and development of a spiritual legacy document (SLD. Methods: Eligible participants were enrolled and completed baseline questionnaires. They were interviewed by a board-certified chaplain about spiritual influences, beliefs, practices, values, and spiritual struggles. An SLD was prepared for each participant, and one month follow-up questionnaires were completed. Two cases are summarized, and spiritual development themes are illustrated within a spiritual development framework. Results: A total of 27 patients completed baseline questionnaires and the interview; 24 completed the SLD, and 15 completed the follow-up questionnaire. Increases in SWB, religious coping, and QOL were detected. The majority maintained the highest (best scores of negative religious coping, demonstrating minimal spiritual struggle. Conclusions: Despite the challenges of brain cancers and other neurodegenerative diseases, participants demonstrated improvements in SWB, positive religious coping, and QOL. Patient comments indicate that benefit is related to the opportunity to reflect on and integrate spiritual experiences and to preserve them for others. Research with a larger, more diverse sample is needed, as well as clinical applications for those too vulnerable to participate in longitudinal follow-up.

  13. PARK7/DJ-1 dysregulation by oxidative stress leads to magnesium deficiency: implications in degenerative and chronic diseases.

    Disturbed magnesium (Mg(2+)) homoeostasis and increased levels of OS (oxidative stress) are associated with poor clinical outcomes in patients suffering from neurodegenerative, cardiovascular and metabolic diseases. Data from clinical and animal studies suggest that MD (Mg(2+) deficiency) is correlated with increased production of ROS (reactive oxygen species) in cells, but a straightforward causal relationship (including molecular mechanisms) between the two conditions is lacking. The multifactorial protein PARK7/DJ-1 is a major antioxidant protein, playing a key role in cellular redox homoeostasis, and is a positive regulator of AR (androgen receptor)-dependent transcription. SLC41A1 (solute carrier family 41 member 1), the gene encoding a ubiquitous cellular Mg(2+)E (Mg(2+)efflux) system, has been shown to be regulated by activated AR. We hypothesize that overexpression/up-regulation of PARK7/DJ-1, attributable to OS and related activation of AR, is an important event regulating the expression of SLC41A1 and consequently, modulating the Mg(2+)E capacity. This would involve changes in the transcriptional activity of PARK7/DJ-1, AR and SLC41A1, which may serve as biomarkers of intracellular MD and may have clinical relevance. Imipramine, in use as an antidepressant, has been shown to reduce the Mg(2+)E activity of SLC41A1 and OS. We therefore hypothesize further that administration of imipramine or related drugs will be beneficial in MD- and OS-associated diseases, especially when combined with Mg(2+) supplementation. If proved true, the OS-responsive functional axis, PARK7/DJ-1-AR-SLC41A1, may be a putative mechanism underlying intracellular MD secondary to OS caused by pro-oxidative stimuli, including extracellular MD. Furthermore, it will advance our understanding of the link between OS and MD. PMID:26453619

    Oxygen-ozone nucleolysis (ONL) is a new, minimally invasive procedure for the treatment of discogenic low back pain with or without radicular symptoms. The aim of the present study was to determine associations between the morphology of the basic disease, patient-specific factors and the outcome of the treatment. Six hundred and twelve patients not responding to conservative therapy were divided into five groups (disc bulging, disc herniation, postoperative patients, osteochondrosis, others) and subjected to nucleolysis with ozone and to periradicular infiltration with steroids and local anaesthesia. The success of treatment was assessed by means of a visual analog pain scale (VAS) and the Oswestry Disability Index (ODI). A significant reduction in the VAS was registered after 2 and 6 months (from 8.6 to 5.4 and 6.0; p<0.001) in all patient groups; an excellent therapy response (VAS below 3.0) was achieved by about a third of the patients. A significant improvement in ODI was registered in all patients (46 to 31; p<0.001), most pronounced in the herniation group (25.5, p=0.015). Patients below 50 years had significantly better values in the VAS and ODI score 6 months after treatment. Final VAS and ODI scores for patients with a single diseased segment were 4.2 and 28.0, in two affected segments 6.5 and 32 and in three segments 6.7 and 38.5 (p<0.001 and p=0.051). ONL with periradicular steroid therapy might exert a functional and sustained analgesic effect in patients with degenerative changes in the lumbar spine not responding to conservative therapy and was most effective below 50 years with disc herniation in one segment.

  16. REM sleep behavior disorder and REM sleep without atonia as an early manifestation of degenerative neurological disease.

    McCarter, Stuart J; St Louis, Erik K; Boeve, Bradley F

    2012-04-01

    Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia characterized by repeated episodes of dream enactment behavior and REM sleep without atonia (RSWA) during polysomnography recording. RSWA is characterized by increased phasic or tonic muscle activity seen on polysomnographic electromyogram channels. RSWA is a requisite diagnostic feature of RBD, but may also be seen in patients without clinical symptoms or signs of dream enactment as an incidental finding in neurologically normal individuals, especially in patients receiving antidepressant therapy. RBD may be idiopathic or symptomatic. Patients with idiopathic RBD often later develop other neurological features including parkinsonism, orthostatic hypotension, anosmia, or cognitive impairment. RSWA without clinical symptoms as well as clinically overt RBD also often occurs concomitantly with the α-synucleinopathy family of neurodegenerative disorders, which includes idiopathic Parkinson disease, Lewy body dementia, and multiple system atrophy. This review article considers the epidemiology of RBD, clinical and polysomnographic diagnostic standards for both RBD and RSWA, previously reported associations of RSWA and RBD with neurodegenerative disorders and other potential causes, the pathophysiology of which brain structures and networks mediate dysregulation of REM sleep muscle atonia, and considerations for the effective and safe management of RBD.

    OBJECTIVE: To determine whether joint synovitis and tendon friction rubs (TFRs) can predict the progression of systemic sclerosis (SSc) over time. PATIENTS AND METHODS: We performed a prospective cohort study that included 1301 patients with SSc from the EUSTAR database with disease duration ≤3...... years at inclusion and with a follow-up of at least 2 years. Presence or absence at clinical examination of synovitis and TFRs was extracted at baseline. Outcomes were skin, cardiovascular, renal and lung progression. Overall disease progression was defined according to the occurrence of at least one...... organ progression. RESULTS: Joint synovitis (HR: 1.26, 95% CI 1.01 to 1.59) and TFRs (HR: 1.32, 95% CI 1.03 to 1.70) were independently predictive of overall disease progression, as were also the diffuse cutaneous subset (HR: 1.30, 95% CI 1.05 to 1.61) and positive antitopoisomerase-I antibodies (HR: 1...

  18. Expression of CGRP in the temporomandibular joint

    The presence and content of calcitonin gene-related peptide (CGRP) is evaluated in the hyperplastic retrodiscal tissue of the temporomandibular joint in patients with joint degenerative disease by radioimmunoassay. Study population has included 8 female patients in pre-menopausic status, without to be pregnant, without to be lactating for a year and with diagnostic of joint degenerative disease (osteoarthrosis). Pain levels are registered with visual analog scale, where 0 is absence of pain and 16 acute pain. A bone degeneration is classified as mild, moderate and severe, according to findings of nuclear magnetic resonance. The 15 retrodiscal hyperplastic tissue samples are taken from patients undergoing to open surgery of temporomandibular joint. The specimens were placed in plastic blocks with freezing medium and are stored at -70 degrees celsius until neuropeptide extraction by radioimmunoassay with kit for CGRP. A directly proportional relationship is established between the degree of bone degeneration and neuropeptide expression and between the osteoarthrosis classification with analogue visual scale. Findings have shown definitive correlation between pain levels and expression of neuropeptide. CGRP is expressed in the retrodiscal tissue of temporomandibular joint in human with joint degenerative disease and is directly related with levels osteoarthrosis and pain

    The treatment of adult degenerative scoliosis begins in the outpatient setting when evaluating a patient both radiographically. Assessing the flexibility of the deformity is essential in determining what techniques will be required to achieve the goals of correction. Ultimately the surgeon's comfort and experience and the patient's medical risk stratification determine the strategy needed to address either a focal pathology or ultimate deformity correction.

  6. Degenerative disc disease as a cause of back pain in the thalassaemic population: a case-control study using MRI and plain radiographs

    The aim of this study was to test our observation that back pain in thalassemic patients could be caused by premature and extensive lumbar degenerative disc disease, when compared to non-thalassemic patients with back pain. Sixteen thalassemic patients with their sex- and age-matched controls were recruited into the study, 12 with thalassemia major, and 4 with thalassemia intermedia. Both the thalassemia patients and control subjects suffered from back pain, which was subjective rather than measured/pain scored. All subjects underwent magnetic resonance (MR) imaging of the lumbar spine, and 11 of the cases and 8 controls had lumbar spine radiographs. Each lumbar disc was scored for radiographic appearances and MR features of disc degeneration and disc protrusion. Proportion values for these parameters and median scores were derived at each disc level, and were analyzed and compared. There was a statistically-significant difference between proportion values of cases and controls for the MR features (P value=0.01, n=16) and the radiographic features (P value=0.01, n=11 cases, n=8 controls) of disc degeneration. The median disc level scores for the thalassemic group were uniformly high across all lumbar discs, and at all levels except at L 4/5. The control group conversely demonstrated a predilection for disc degeneration at L4/5 level. The distribution of lumbar disc degeneration in thalassemic patients with back pain is more extensive, severe and multi-level in nature compared to matched controls, and disc degeneration should be considered as a significant cause of back pain in this population group.

    Anterior cervical discectomy and fusion, to date the most successful spine procedure for the surgical treatment of cervical radiculopathy, has limitations that have led to the development of non-fusion cervical procedures, such as cervical total disc replacement (TDR) and dynamic cervical implant (DCI) arthroplasty. We compared the clinical and radiological results of DCI and cervical TDR for the treatment of single-level cervical degenerative disc disease in Chinese patients. A retrospective review of 179 patients with cervical spondylotic myelopathy who underwent DCI or TDR between April 2010 and October 2012 was conducted, and 152 consecutive patients (67 patients single-level DCI and 85 single-level TDR) who completed at least 2years of follow-up were included. Clinical and radiological assessments were performed preoperatively and at 1week and 3, 6, 12, and 24months postoperatively. The most common operative level was C5/C6 (49.3%). The differences in blood loss, duration of surgery, and duration of hospitalization were not statistically significant. The Japanese Orthopaedic Association scale, Visual Analog Scale, Neck Disability Index, and Short Form-36 scores improved significantly after surgery in both the DCI and TDR groups (P<0.05), but the differences were not statistically significant at the final follow-up. The rate of occurrence of heterotopic ossification was 22.4% and 28.2% in the DCI and TDR groups, respectively. As an effective non-fusion technique, DCI is a more economical procedure. Further prospective, randomized studies with long-term follow-up periods are needed to determine the long-term effects. PMID:26928156

    Intervertebral disc degeneration is a major cause of low back pain. The nucleus pulposus (NP) is an important intervertebral disc component. Recent studies have shown that carbonic anhydrase 12 (CA12) is a novel NP marker. However, the mechanism by which CA12 is regulated and its physiological function are unclear. In our study, CA12, hypoxia-inducible factor 1α (HIF-1α) and HIF-2α expression levels were examined in 81 human degenerated NP samples using real-time RT-PCR, immunohistochemistry and western blot. Rat NP cells were cultured in a hypoxic environment, and hypoxia-induced CA12 expression was examined. Rat NP cells were treated with HIF-1α siRNA or the prolyl hydroxylase (PHD) inhibitor dimethyloxalylglycine (DMOG) to evaluate the role of PHD/HIF-1 in regulating CA12 expression. Rat NP cells were treated with CA12 siRNA to determine the function of CA12. A rat ex vivo model was established to confirm that PHD, HIF-1, and CA12 have important roles in disc degeneration. We found that CA12 was significantly downregulated in degenerated human NP samples at the mRNA and protein levels. CA12 expression sharply increased by ~30-fold in response to hypoxia. The expression of HIF-1α, but not HIF-2α, also decreased in degenerated human NP samples and was positively correlated with CA12 expression. HIF-1α knockdown under hypoxia reduced the CA12 mRNA and protein expression levels. DMOG treatment increased HIF-1α and CA12 expression. CA12 knockdown significantly inhibited anabolic protein expression, whereas catabolic enzymes remained unchanged. The ex vivo experiments supported our in vitro studies of the role of PHD/HIF-1/CA12. In conclusion, CA12 is downregulated in degenerated NPs, and its expression may be regulated by the PHD/HIF-1 axis. Decreased CA12 expression may lead to decreased extracellular matrix synthesis, which contributes to degenerative disc disease progression. PMID:26901836

  12. Atherosclerotic cardiovascular disease in patients with chronic inflammatory joint disorders.

    Agca, R; Heslinga, S C; van Halm, V P; Nurmohamed, M T

    2016-05-15

    Inflammatory joint disorders (IJD), including rheumatoid arthritis (RA), ankylosing spondylitis (ASp) and psoriatic arthritis (PsA), are prevalent conditions worldwide with a considerable burden on healthcare systems. IJD are associated with increased cardiovascular (CV) disease-related morbidity and mortality. In this review, we present an overview of the literature. Standardised mortality ratios are increased in IJD compared with the general population, that is, RA 1.3-2.3, ASp 1.6-1.9 and PsA 0.8-1.6. This premature mortality is mainly caused by atherosclerotic events. In RA, this CV risk is comparable to that in type 2 diabetes. Traditional CV risk factors are more often present and partially a consequence of changes in physical function related to the underlying IJD. Also, chronic systemic inflammation itself is an independent CV risk factor. Optimal control of disease activity with conventional synthetic, targeted synthetic and biological disease-modifying antirheumatic drugs decreases this excess risk. High-grade inflammation as well as anti-inflammatory treatment alter traditional CV risk factors, such as lipids. In view of the above-mentioned CV burden in patients with IJD, CV risk management is necessary. Presently, this CV risk management is still lacking in usual care. Patients, general practitioners, cardiologists, internists and rheumatologists need to be aware of the substantially increased CV risk in IJD and should make a combined effort to timely initiate CV risk management in accordance with prevailing guidelines together with optimal control of rheumatic disease activity. CV screening and treatment strategies need to be implemented in usual care. PMID:26888573

  15. Somatomedin activity in synovial fluid from patients with joint diseases

    The somatomedin activity in synovial fluids from 50 patients with a variety of joint diseases has been studied and compared with the activity in each of the Patient's own serum and a standard reference serum (SRS). The porcine costal cartilage bioassay of Van den Brande and Du Caju (Acta Endocrinologica, 75, 233, 1974), has been used with the isotopes 3H-thymidine and 35S-sulphate. Synovial fluids from most patients with post-traumatic and post-operative effusions, osteoarthritis and arthritis associated with psoriasis, Reiter's disease, and ankylosing spondylitis stimulated the synthesis of DNA and proteoglycans in cartilage. Synovial fluids from patients with rheumatoid arthritis either had impaired capacity to stimulate DNA synthesis, or they inhibited it; a similar, but less evident pattern was observed for proteoglycan synthesis. Some synovial fluids from patients with miscellaneous synovitides stimulated, while other inhibited cartilage metabolism. It is concluded that the synovial fluid from patients with rheumatoid arthritis and from patients with miscellaneous synovitides contained an inhibitor(s) to DNA and possible proteoglycan synthesis. The sera from nearly all the patients stimulated both DNA and proteoglycan synthesis, but the somatomedin potency ratios for serum in terms of SRS were generally less than 1.0. There was a significant inverse correlation between the serum somatomedin potency ratio and the age of the patient. (author)

METHOD: 14 patients with PD and 14 patients with CD matched by sex, education, disease's duration and MMSE were selected. A standardized neuropsychological battery and the Wisconsin Card Sorting Test (WCST were administered. Z scores were compared for both groups through t-test for independent samples were used. RESULTS: The cerebellar group showed significant lower performance in measures of attention and EF, with a significant increase in both perseverative and non perseverative errors during the WCST. On the other hand the PD group showed a selective increase of non perseverative errors, without reaching significant between group difference. CONCLUSION: The CD group appears to have greater deficits in EF with a pattern of prefrontal dysfunction.

    Stereotypies are simple or complex involuntary/unvoluntary behaviors, common in fronto-temporal dementia (FTD), but not studied in other types of degenerative dementias. The aim was to investigate stereotypy frequency and type in patients with FTD, Alzheimer's disease (AD), progressive supranuclear palsy (PSP) and Parkinson's disease with dementia (PDD) in a multicenter observational study; and to investigate the relation of stereotypies to cognitive, behavioral and motor impairment. One hundred fifty-five consecutive outpatients (45 AD, 40 FTD, 35 PSP and 35 PDD) were studied in four hospitals in northern Italy. Stereotypies were examined by the five-domain Stereotypy Rating Inventory. Cognition was examined by the Mini Mental State and Frontal Assessment Battery, neuropsychiatric symptoms by the Neuropsychiatric Inventory, and motor impairment and invalidity by the Unified Parkinson's Disease Rating Scale part III, and activities of daily living. Stereotypies were present in all groups. FTD and PDD had the greatest frequency of one-domain stereotypies; FTD also had the greatest frequency of two-or-more domain stereotypies; movement stereotypies were the most common stereotypies in all groups. AD patients had fewer stereotypies than the other groups. Stereotypies are not exclusive to FTD, but are also fairly common in PSP and PDD, though less so in AD. Stereotypies may be underpinned by dysfunctional striato-frontal circuits, known to be damaged in PSP and PDD, as well as FTD. PMID:22648476

  19. In vitro and in vivo spin echo diffusion imaging characteristics of synovial fluid: potential non-invasive differentiation of inflammatory and degenerative arthritis

    Objective. This study was undertaken to analyse the diffusion characteristics of synovial fluid in degenerative and inflammatory arthropathies.Design and patients. Ten in vitro specimens of synovial fluid from patients with both degenerative and inflammatory arthropathy were studied at body temperature with a navigator-corrected spin echo diffusion sequence (B values 0-512 s/mm2), on a Philips 1.5-T Gyroscan. Subsequently synovial fluid from knee joint effusions of 25 patients (10 patients with osteoarthritis, 10 patients with effusions following trauma and 5 patients with effusions secondary to inflammatory arthritis) was evaluated with the same navigator-corrected spin echo diffusion sequence.Results. Both in vitro and in vivo study demonstrated decreased diffusion in patients with effusions secondary to degenerative joint disease (less than 2.40 x 10-5 cm2/s) relative to patients with effusions accompanying knee trauma (greater than 2.75 x 10-5 cm2/s) and inflammatory arthritis (in vitro and in vivo greater than 3.00 x 10-5 cm2/s).Conclusion. Synovial fluid in degenerative arthritis shows less diffusion or free water movement than synovial fluid in inflammatory arthritis. Diffusion characteristics of synovial fluid may be used to predict the nature of the underlying form of arthritis in patients presenting with knee joint effusions. (orig.)

  2. Classification, clinical findings and operative treatment of degenerative and posttraumatic shoulder disease What do we really need to know from an imaging report to establish a treatment strategy?

    Successful patient care involves interdisciplinary Cupertino. Images allow an interpretation of a static dimension, but may not be sufficient to develop a surgical treatment strategy, since many shoulder problems have its origin in a dynamic pathology. This article outlines dynamic clinical tests of shoulder pathology, classifies various degenerative and posttraumatic shoulder problems and stresses key facts an imaging report should include in order to plan surgery. This article conveys basic knowledge of those tests and the dynamic background of shoulder pathology. Basic surgical treatment principles are summarised briefly

    2007-02-15

    Purpose: To examine degenerative features based on magnetic resonance imaging (MRI) measurements at the lumbar spine in relation to dual-energy X-ray absorptiometry (DXA), and to investigate whether bone mineral density (BMD) is reflected in the substitution of bone trabecular structure by fat at the vertebral body level indicated by MRI T1 relaxation time, endplate concavity, and hypertrophic (osteophytes and endplate sclerosis) MRI findings. Material and Methods: The sample for this cross-sectional study was composed of 102 subjects, 35-70 years old, from a population-based cohort. Data collection included DXA in the anterior-posterior projection at the L1-L4 vertebrae and right femoral neck, and MRI of the lumbar spine in the midsagittal plane. Results: Age, vertebral signal intensity, osteophytes, and endplate concavity collectively explained 20% of the variance in spine BMD. Conclusion: The study findings suggest that degenerative findings based on MRI measurements at the lumbar spine have an influence on bone assessment using DXA. Therefore, an overall bone assessment such as DXA might not offer an accurate measure of BMD.

    Full Text Available This study aimed at making the differential diagnosis of joint disease in a case of genetic chimerism in a female multiparous donor from the Regional Blood Bank of Guarapuava-PR (Hemocentro Regional de Guarapuava-PR, who had had three pregnancies of male fetuses. The patient showed joint pain prior to the last donation. It was possible to identify fetal cells remaining in circulation 20 years after her last pregnancy. Laboratory tests for acute phase proteins revealed possible termination of immune tolerance to circulating fetal cells. Thus, a hypothesis of graft-versus-host disease was formulated to explain the joint disease manifested by the donor.

    The clinical presentation of spinal tumors is known to vary, in many instances causing a delay in diagnosis and treatment, especially with benign tumors. Neck or back pain and sciatica, with or without neurological deficits, are mostly caused by degenerative spine and disc disease. Spinal tumors are rare, and the possibility of concurrent signs of degenerative changes in the spine is high. We report a series of ten patients who were unsuccessfully treated for degenerative spine disease. They ...

The facet joint and osteophyte images were observed in particular, and the slipping ratio of spondylolisthetic vertebrae was determined. The slipping ratio of degenerative spondylolisthesis ranged from 11.8 % to 22.3 %. Hot uptake of 99mTc-HMDP by both L4-5 facet joints was significantly greater in the patients with degenerative spondylolisthesis than in those with lumbar spondylosis. The hot uptake by the osteophytes in lumbar spondylosis was nearly uniform among the three inferior segments, L3-4, L4-5 and L5-S, but was localized to the spondylolisthetic vertebrae, L4-5, or L5-S, in the patients with spondylolisthesis. Half of the osteophytes with hot uptake were assigned to the 3rd degree of Nathan's grading. It was suggested that stress was localized to the slipping vertebrae and their facet joints in patients with lumbar degenerative spondylolisthesis. (author)

  13. Development of PET tracers for neuro inflammation imaging in neuro degenerative diseases; Developpement de radiotraceurs de la neuroinflammation pour l'imagerie des pathologies neurodegeneratives

    Chauveau, F

    2007-10-15

    Inflammatory processes such as micro-glial or endothelial activation are involved in many neuro-degenerative conditions. Neuro-inflammation imaging is considered an attractive tool for fundamental research, diagnosis and therapeutic evaluation in neuro-pathologies. First, an aptamer was selected against a recombinant fragment of the endothelial target VCAM-1, but proved unable to bind the target protein in native conformation, as expressed by a cell line. Second, five radioligands of the peripheral benzodiazepine receptor (PBR), a marker of micro-glial activation, were evaluated in vivo using PET (Positron Emission Tomography) imaging in a rat model of neuro-inflammation, and were compared to [11C]PK11195. Four radiotracers displayed a better contrast than [11C]PK11195. In a competitive field of research, this work demonstrates the efficiency of in vivo screening of radiotracers for fast selection of clinically relevant molecules. (author)

  14. Rheumatoid arthritis affecting temporomandibular joint

    2015-01-01

    Full Text Available Rheumatoid arthritis (RA is a chronic, systemic, autoimmune inflammatory disorder that is characterized by joint inflammation, erosive properties and symmetric multiple joint involvement. Temporomandibular joint (TMJ is very rare to be affected in the early phase of the disease, thus posing diagnostic challenges for the dentist. Conventional radiographs fail to show the early lesions due to its limitations. More recently cone-beam computed tomography (CBCT has been found to diagnose the early degenerative changes of TMJ and hence aid in the diagnosis of the lesions more accurately. Our case highlights the involvement of TMJ in RA and the role of advanced imaging (CBCT in diagnosing the bony changes in the early phase of the disease.

  15. Carpal instabilities and secondary degenerative changes due to lesions of the radiocarpal ligament complex

    This paper reports on trauma, rheumatoid arthritis, calcium pyrophosphate dihydrate crystal deposition (CPDD), neurologic disease, and beta2-microglobulin-related amyloid deposits in patients undergoing chronic hemodialysis that can lead to distinct lesions of the radiocarpal ligament complex, causing rotational subluxation of the scaphoid and ulnar translocation of the carpus. The clinical and radiologic findings were analyzed in 35 patients, examined from 1985 to 1989. Degenerative changes in rotational subluxation of the scaphoid develop in three steps. First there is osteoarthritis at the styloid process, then the degeneration progresses into the central midcarpal joint, and finally it progresses to the ulnar midcarpal joint. Despite different etiologies of ligament failure, the radiologic features are very similar, because the mechanism of degeneration is identical in posttraumatic, inflammatory, neurogenic, CPDD, or beta2-microglobulin-related instability. However, there are some distinct radiologic differences in relation to the primary cause of the ligament defect

  16. Lipoma arborescens: Comparison of typical and atypical disease presentations

    Aim: To determine whether the aetiology differed between typical cases of lipoma arborescens with unilateral knee involvement and atypical cases involving joints other than the knee, polyarticular disease, and disease outside of the knee joint. Materials and methods: Cases of lipoma arborescens involving the knee joint were evaluated for the distribution of the disease and severity of degenerative arthritis. Joints other than the knee were evaluated for the presence and severity of degenerative arthritis, and the distribution was classified as either intra-articular, extra-articular, or both. Clinical history was reviewed for patient age at presentation, a history of inflammatory arthritis, diabetes mellitus, and known steroid use. Fisher's exact test was used to determine whether there was a statistically significant difference between typical and atypical presentations of the disease. Results: Lipoma arborescens was identified in 45 joints in 39 patients. Twenty-eight patients were classified as “typical” and 11 patients had “atypical” disease. There was no significant difference in age at presentation, presence of degenerative arthritis, or known inflammatory arthritis when comparing typical and atypical presentations of the disease. Conclusion: Twenty-eight percent of patients in the present study had atypical presentation of lipoma arborescens with multifocal lipoma arborescens or disease in joints other than the knee. There was no significant difference in age at presentation, presence of degenerative arthritis, or known inflammatory arthritis when comparing typical and atypical presentations of the disease. Of the 39 patients, only three had no evidence of degenerative arthritis, which suggests that many cases of lipoma arborescens are secondary to chronic reactive change in association with degenerative arthritis

  18. CT findings of isthmic spondylolisthesis and degenerative spondylolisthesis

    CT evaluate the finding useful for differential diagnosis and associated abnormalities of isthmic spondylolisthesis and degenerative spondylolisthesis on CT. We reviewed retrospectively the CT images of 164 patients who were diagnosed spondylolisthesis. One hundred twelve patients had isthmic spondylolisthesis and 52 patients had degenerative spondylolisthesis. Isthmic spondylolisthesis most frequently occurred at L5. The degree of anterior displacement was grade I and II. The defect had a horizontal plane, an irregular surface, a sclerotic margin, and protruding hypertrophic bony spur in the spinal canal. The most frequently associated structural abnormality was a herniated nucleus pulposus at the upper level of the defect. Degenerative spondylolisthesis most frequently occurred at L4-5 and were grade I. The degenerative facet joint had a vertical plane, a hypertrophic bony spur, and a vacuum facet phenomenon. We frequently detected a pseudobulging disk. The most frequently associated structural abnormality was a herniated nucleus pulposus at the level of the displacement. In spondylolisthesis, the findings in CT were valuable for differential diagnosis of isthmic and degenerative types and the detection of associated symptomatic abnormalities

    1983-01-01

    The prognosis 3 years after the onset of the disease was studied in 107 patients with definite rheumatoid arthritis, 161 with probable RA or non-specific arthritis, 84 with either ankylosing spondylitis, Reiter's disease or reactive arthritis, 14 with psoriatic arthritis and 10 with a systemic connective tissue disease. Prognosis was measured by clinical involvement of joints, radiological erosions in joints, deterioration in joint function, ESR, and working ability. A total of 44% of all patients were symptomless after 3 years. The prognosis was best in patients with an "HLA B 27-associated" disease and non-specific arthritis, and worst in RA. Two patients died during the follow-up of systemic connective tissue disease and one committed suicide with an overdose of hydroxychloroquine. Two HLA B27-positive patients developed systemic amyloidosis. PMID:6836238

  3. Equine degenerative myeloencephalopathy.

    Miller, M M; Collatos, C

    1997-04-01

    EDM is a neurologic disease of young horses characterized by the insidious development of symmetric ataxia. Decreased or absent cutaneous trunci reflex or slap test responses are considered clinical signs that increase the index of suspicion for this disease. In addition, concurrent predisposing factors, such as familial history, inadequate access to green pasture, and possible exposure to wood preservatives or insecticides, provide further supporting evidence for a clinical diagnosis. Vitamin E deficiency and a hereditary predisposition currently are considered the most significant factors in the pathogenesis of this disease. Histopathologically the lesions of EDM are those of neuraxonal dystrophy, characterized by prominent axonal and dendritic swelling, mild glial proliferation, and neuronal depletion and atrophy with lipofuscin-like pigment accumulation. Animals predisposed to EDM or with a clinical diagnosis of EDM should receive oral alpha-tocopherol acetate supplementation. Improvement in clinical signs may be seen following long-term treatment, but in general, the prognosis for complete recovery is poor. PMID:9106342

    There is no reliable predictor for therapeutic efficacy for temporomandibular joint (TMJ) disease. The aim of the present study was to evaluate the usefulness of Tc-99m HDP bone scan in the pre-therapeutic assessment of prognosis for TMJ disease. Between January 2005 and July 2007, 94 patients (M: F=18: 76; mean age, 33.4{+-}14.0 y) with TMJ disease who underwent pre-therapeutic bone scan were enrolled. Planar bone scan images were obtained at right and left lateral skull areas 3 hours post Tc-99m HDP injection (dose=1295 MBq). TMJ uptake of Tc-99m HDP was quantitated using 13X13 pixel-square region-of-interest over TMJ and parietal skull area as background. TMJ uptake ratio was calculated as; (TMJ background) / background. Asymmetric indices for involved TMJ uptake (Al{sub invovle}) were defined as; TMJ uptake ratio of involved/non-involved joint. Asymmetric indices for greater TMJ uptake regardless of disease involvement (AI{sub greater}) were defined as; TMJ uptake ratio of greater/smaller TMJ uptake. Splint therapy was applied to all patients with mean duration of 7 months (range; 3-34 months). Therapeutic efficacy was dichotomised as improved or non-improved in consideration of mandibular movement, TMJ noise, pain, and tenderness. Seventy-six patients experienced improvement, whereas 18 patients non-improvement. There was no significant difference between improved versus non-improved patients regarding TMJ uptake ratio of involved joint (2.92{+-}0.82 vs. 2.91{+-}0.66), and AI{sub invovle} (1.16{+-}0.22 vs. 1.10{+-}0.12) (p>0.05, t-test). However, AI{sub greater} was significantly higher in improved patients than non-improved patients (1.20{+-}0.19 vs. 1.13{+-}0.09, p<0.05, t-test). Regardless of disease involvement of TMJ disease, asymmetricities of Tc-99m HDP uptake were more frequently found in improved group after splint therapy. Tc-99m HDP bone scan can predict the efficacy of splint therapy in TMJ disease.

    The purpose of this study was to describe pathological changes of the shoulder, elbow, hip and stifle joints of 16 museum skeletons of the raccoon dog (Nyctereutes procyonoides). The subjects had been held in long-term captivity and were probably used for fur farming or research, thus allowing sufficient longevity for joint disease to become recognisable. The prevalence of disorders that include osteochondrosis, osteoarthritis and changes compatible with hip dysplasia, was surprisingly high. ...

  7. The degenerative and traumatized knee: Use of radioisotopes for diagnosis, evaluation and treatment

    Full text: Bone SPECT is a highly valuable method of investigation for the assessment of the knee joint. Its speed and low cost probably make it a suitable screening procedure for most knee traumatic and degenerative diseases. Consequently, bone SPECT is inevitably seen as a competitive and complementary procedure to MRI. The technique of radiation synovectomy has been available for more than 40 years in the management of joint diseases. Recently, there has been renewed interest in radiation synovectomy, following the introduction of some new and efficient radiopharmaceuticals. We present here our experience with the diagnosis and treatment of the traumatized and degenerative knees in 358 patients, together with the review of the literature. A special emphasis will be placed on the following topics: 1. Correlative imaging of planar and SPECT scintigraphy with correlation to MRI. 2. Quantitative and prognostic parameters. 3. The value of the method in sports and military medicine. 4. The value of bone scintigraphy in choosing candidates and planning arthroscopic and radiation synovectomy. 5. The clinical efficacy of particulate versus colloid radiopharmaceutical for radiation synovectomy. 6. The response rate to a single injection versus routine repeated injections of the radiopharmaceutical. 7. The clinical importance of some different techniques of treatment in different clinics, including injected dose, injection procedure, safety precautions, etc. 8. Comparison of the efficacy of radiation synovectomy to intra-articular corticosteroid injection. 9. The use of different 90Y colloids (resin, citrate, cilicate and ferric hydroxide), comparing especially the extent of regional lymph node irritation as a result of joint leakage. 10. The clinical importance of co-injection of corticosteroids with the radiopharmaceutical, in either colloidal or particular radiopharmaceuticals. 11. The importance of combined procedures of saline irrigation with radiopharmaceutical and/or possible corticosteroid injection, for improving patients' outcome. 12. The value of post treatment full rest (hospitalization?) to prevent extra- articular leakage and optimal response. 13. Some financial and cost-effective considerations. (author)

  8. Investigation of the spine by single photon emission computed tomography (SPECT) in rheumatoid spondylitis, in degenerative, traumatic and malignant diseases of the spine and in osteoid-osteoma

    SPECT has been used in a comparative study with planar bone scintigraphy in 54 patients. Spatial resolution of the method is sufficient to localise the vertebral bodies, the spinous processes, the intervertebral, costotransverse and costovertebral joints. In all patients it was possible to relate the areas of increased uptake to specific anatomical sites of the spine known to be affected in the different conditions. A detailed localisation is rarely possible using planar scintigraphy alone, due to the complex osseous anatomy of the spine. In some patients lesions could be seen only with SPECT. SPECT is an invaluable supplement to planar scintigraphy of the spine. (orig)

Chronic low back pain originating in the sacroiliac (SI joint (15%30% of cases is commonly treated with nonoperative care, but new minimally invasive surgery (MIS options are also effective in treating SI joint disruption. We assessed whether the higher initial MIS SI joint fusion procedure costs were offset by decreased nonoperative care costs from a US commercial payer perspective. Methods: An economic model compared the costs of treating SI joint disruption with either MIS SI joint fusion or continued nonoperative care. Nonoperative care costs (diagnostic testing, treatment, follow-up, and retail pharmacy pain medication were from a retrospective study of Truven Health MarketScan data. MIS fusion costs were based on the Premier's Perspective Comparative Database and professional fees on 2012 Medicare payment for Current Procedural Terminology code 27280. Results: The cumulative 3-year (base-case analysis and 5-year (sensitivity analysis differentials in commercial insurance payments (cost of nonoperative care minus cost of MIS were $14,545 and $6,137 per patient, respectively (2012 US dollars. Cost neutrality was achieved at 6 years; MIS costs accrued largely in year 1 whereas nonoperative care costs accrued over time with 92% of up front MIS procedure costs offset by year 5. For patients with lumbar spinal fusion, cost neutrality was achieved in year 1. Conclusion: Cost offsets from new interventions for chronic conditions such as MIS SI joint fusion accrue over time. Higher initial procedure costs for MIS were largely offset by decreased nonoperative care costs over a 5-year time horizon. Optimizing effective resource use in both nonoperative and operative patients will facilitate cost-effective health care delivery. The impact of SI joint disruption on direct and indirect costs to commercial insurers, health plan beneficiaries, and employers warrants further consideration.

    A case of Lyme arthritis with advanced degenerative changes localized to the midcarpal joint was treated with a limited wrist arthrodesis with relief of pain and improved function. Chronic Lyme arthritis occurs as the third stage of Lyme disease. Serologic testing and a history of a characteristic rash may be helpful in the diagnosis. Radiographic and histopathologic findings are nonspecific, with both degenerative and inflammatory characteristics. Intravenous antibiotics provide an effective treatment of chronic Lyme arthritis.

  14. MRI of cystic collection of the three joint

    We present the main MR features of cystic lesions around the knee joint. Popliteal cysts are the most frequently seen. The usually result from extrusion of joint fluid into the gastrocnemio-semimembranosus bursa but they can have an atypical location or extension. They are most often due to a meniscal, ligamentous, degenerative or inflammatory joint disease responsible for a chronic joint effusion. Meniscal cysts are always associated with a horizontal tear. Medial meniscal cysts are larger and can extend far from the joint. Bursitis occur as a result of inflammation or infection of a bursa. Their location is stereotyped and they do not communicate with the knee joint. Ganglion cysts or ganglia are benign cystic lesions which can affect peri-articular tissues as well as subchondral bone or cruciate ligaments. MRI is now a simple and noninvasive way of obtaining etiologic diagnosis and guiding therapy. (authors)

  15. Some cellular aspects of chronic inflammation in joint disease.

    Loewi, G; Reynolds, J

    1976-02-01

    We have examined the nature of some mononuclear cells from inflamed synovial membranes of patients with rheumatoid arthritis. It was found that cells which remained in the supernatant medium after overnight culture of trypsinized tissue contained a variable number of lymphocytes which were shown to be T cells by rosetting and mitogen response. This suggests a source of T cell lymphokines with an effect on macrophages and thus a role in the maintenance of inflammation. Another role for mononuclear cells is suggest by the cytotoxicity of blood mononuclear cells directed against cultured synovial cells. This was found to occur in an autologous system using fibroblasts from rheumatoid synovium, but was not specific for rheumatoid arthritis. Stimulatory factors from rheumatoid joint effusion macrophages for blood lymphocytes were sought, but although blast transformation occurred, the results were equivocal. In this communication we set out to examine the nature of lymphoid cells in the synovial membrane and the role which they may play in the pathogenesis of chronic inflammation. We also briefly consider cell-mediated mechanisms of tissue injury. Since an active role of lymphoid cells pre-supposes the presence of an agent or agents which serve to stimulate them, we also report some recent attempts to find evidence for this. One of the striking histological features of the inflamed synovial tissue in rheumatoid arthritis, but also in some other forms of chronic arthritis, is the presence of lymphocytes and plasma cells. Immunofluorescent studies and organ culture studies have shown the presence and synthesis of immunoglobulins, predominantly the domain of plasma cells. The production of immunoglobulins, formation of complexes and activation of complement is a major factor in pathogenesis, but lymphocytes may also have a direct role through the production of lymphokines. Until recently these substances have been attributed to T lymphocytes, but Rocklin et al. (1) have recently shown that B cells may also be involved in certain experimental circumstances. The availability of synovectomy specimens from patients with rheumatoid arthritis has enabled us to examine the nature of lymphoid cells from synovial membranes.

  16. Scintigraphy, thermography and ultrasound in the diagnosis of inflammatory knee joint diseases

    The paper reports on the results of dynamic scintigraphy with 99mTc-pertechnetate, contact plate liquid crystal thermography and sonography in patients with inflammatory disease of the knee joint. Dynamic scintigraphy and thermography showed the same findings in 89% of the patients in detecting inflammatory hyperaemia. Ultrasound is necessary for detection of 'liquid cavities', such as Baker cysts and arthroceles. (author)

  17. Roentgenological assessment of diaphragm functional state in case of degenerative dystrophic injuries of the skeleton

    The results of complex clinicoroengenological investigations of patients with degenerative dystrophic injuries of the backbone are presented. It is shown that the conditions of functioning of the inspiratory muscle group greatly change in the case of this pathology. The most typical picture is observed during the disease exacerbation when costovertebral and costotrasverse joints were drawn into the process. The greater increase of the motion amplitude corresponding to a half of the diagram was revealed in the presence of a considerably more pronounced osteoarthosis phenomena from any side. The necessity is shown to take into account in the case of osteochondrosis of the cervical and thoracal spinal sections the reconstruction of respiration mechanisms takes place

  19. US Assessment of Hip Joint Synovitis in Rheumatic Diseases A comparison with MR imaging

    Purpose: To assess the significance of ultrasonography (US) in detecting hip joint synovitis in patients with rheumatic diseases. Material and Methods: Forty patients with rheumatic disease and suspected hip joint synovitis underwent MRI and US of the hip joint. In addition to the throughout MRI evaluation, the anterior collum-capsule distance (CCD) was determined by both MRI and US. Thirteen healthy volunteers were examined with MRI to establish the criteria for normal findings in MRI when classifying hip joints to those with synovitis and those without. MRI was used as a gold standard. Results: Synovitis was found using MRI in 31 hips of 22 patients (9 patients had bilateral synovitis). The intraclass correlation was 0.61 between MRI and US in measuring CCD. In classifying hip joint synovitis with US, the sensitivity of the method was 87% and specificity 42%, when the CCD criterion for synovitis was determined to be 7 mm. If the cut-off point was raised to 9 mm, the sensitivity decreased to 61% while specificity increased to 94%. A difference in CCD of 1 mm between the hips as an additional criterion for synovitis increased the number of false-positive findings. Conclusion: Measurement of CCD with US proved to be a rather inaccurate method to point out synovitis in rheumatic patients when using MRI as a reference. The main reason for this result was the thickened capsule, which US could not differentiate from a thickened synovium

  20. Value of different MR techniques in diagnosis of degenerative disorders of the hyaline cartilage - in vitro study on 50 joint specimens of the knee with 1.5 T

    Purpose: An experimental study was performed on joint specimens of the knee to assess the advantages and disadvantages of 14 generally available sequences in cartilage imaging. Methods: Each of the 50 surgically exposed cadaveric joints of the knee was examined by the following sequences: T1, proton- and T2 weighted spin echo(SE) sequences, proton- and T2 weighted Turbo-SE, T1 weighted SE with fat suppression, MTC combined with T1-weighted SE and T2 weighted FLASH-2 D, STIR, FISP-3 D, FLASH-3 D (with fat suppression), and MR arthrography. We assessed the image quality by a scale, signal to noise-ratio of cartilage and joint fluid, and the accuracy in detection of cartilage lesions. Pathology and arthroscopy were reference methods to MRI, and demonstrated grade 1-4 lesions on 186 of 300 joint facettes. Results: Advanced stages of cartilage lesions (65 grade 3 and 4 lesions) were detected by standard SE sequences in 67-94%. Application of volume techniques (FISP-3 D, FLASH-3 D), high definition matrix (512 pixel), MTC with FLASH-2 D and MR-arthrography improved the sensitivity up to 82-100%. Superficial lesions (65 grade 2 lesions) were demonstrated in 3-38%, and on MR arthrography in 45%. Structural changes (56 Grade 1 lesions) were recorded on MRI in only 10%. Conclusions: With regard to standard SE sequences, the detectability of cartilage lesions can be improved by techniques that use 512 matrices, selective cartilage imaging, and volume acquisition.

  2. DEGRO guidelines for the radiotherapy of non-malignant disorders. Part II: Painful degenerative skeletal disorders

    The purpose of this article is to summarize the updated DEGRO consensus S2e guideline recommendations for the treatment of benign painful degenerative skeletal disorders with low-dose radiotherapy. This overview reports on the role of low-dose radiotherapy in the treatment of enthesiopathies (shoulder syndrome, trochanteric bursitis, plantar fasciitis, and elbow syndrome) and painful arthrosis (knee, hip, hand, and finger joints). The most relevant aspects of the DEGRO S2e Consensus Guideline Radiation Therapy of Benign Diseases 2014 regarding diagnostics, treatment decision, dose prescription as well as performance of radiotherapy and results are summarized. For all indications mentioned above, retrospective and some prospective analyses have shown remarkable effects in terms of pain relief. Nevertheless, the Level of Evidence (LoE) and the Grade of Recommendation (GR) vary: LoE 1b-4 and GR A-C. Low-dose radiotherapy for painful degenerative skeletal disorders is effective in the majority of the patients and therefore it may be a reasonable therapeutic alternative when simple and non-invasive methods have been used without persistent success. For all discussed entities, single fraction doses of 0.5-1.0 Gy and total doses of 3.0-6.0 Gy/series applied with 2-3 fractions per week are recommended. (orig.)

  3. Radiographic distinction of degenerative slippage (spondylolisthesis and retrolisthesis) from traumatic slippage of the cervical spine

    Lee, C.; Woodring, J.H.; Rogers, L.F.; Kim, K.S.

    1986-08-01

    In a review of 42 cases of degenerative arthritis of the cervical spine and 22 cases of cervical spine trauma with an observed anterior slip-page (spondylolisthesis) or posterior slippage (retrolisthesis) of the vertebral bodies of 2 mm or more, characteristic features were observed which allowed distinction between degenerative and traumatic slippage of the cervical spine. In degenerative slippage the shape of the articular facets and width of the facet joint space may remain normal; however, in most cases the articular facets become 'ground-down' with narrowing of the facet joint space and the articular facets themselves becoming thinned or ribbon-like. In traumatic slippage the articular facets will either be normally shaped or fractured and the facet joint space will be abnormally widened. Plain radiographs will usually allow this distinction to be made; however, in difficult cases polytomography may be required.

  4. Typical MR intensity distribution patterns in different knee joint diseases using a gradient echo sequence

    The knee joints of 31 patients and 3 volunteers were examined with a 1.5 T Magnetom using 3D-gradient echo sequences. We measured for the most widespread diseases: The gonarthrosis (n=23) and rheumatoid arthritis (n=8) the signal intensities in all joint parts and the typical signal plots were worked out. In case of minimal changes at the articular cartilage, the method developed and tried out by us can facilitate diagnosis. A special aspect of this method is also the patient follow-up which is now possible quantitatively and objectively. (orig.)

    2012-04-01

    Full Text Available 【Abstract】Objective: To investigate the material properties of normal and degenerated intervertebral discs (IVDs and examine the effect of degenerative changes on IVD pathology. Methods: A computer-based online search was under-taken to identify English articles about material properties of IVDs published from January 1950 to 2011 in PubMed database. The retrieved keywords included material properties, intervertebral disc and degeneration. Based on the principles of reliability, advancement and efficiency, the obtained data were primarily examined, and the original source was retrieved to read the full-text. Repetitive articles were excluded. The data of material properties of normal and degenerated IVDs were summarized and analyzed by meta-analysis. Results: The data of Young's modulus, Poisson's ratio, shear modulus, hydraulic permeability and intradiscal pres-sure of normal and degenerated IVDs were obtained. Com-pared with normal IVDs, the Young's modulus and shear modulus of annulus fibrosus and nucleus pulposus were higher in degenerated IVDs, the Poisson's ratio was lower while the hydraulic permeability and intradiscal pressure were higher. Besides, the degeneration-related alterations in IVDs had an influence both on itself and other spinal structures, leading to diseases such as bulging disc, discogenic pain and spinal stenosis. Meanwhile, the heavy mechanical loading and injury indicated important pathways to IVD degeneration. Conclusions: To a certain extent, the degenerative changes of IVD influence its material properties. And the degeneration-related alterations of composition can cause structural failure of IVDs, leading to injuries and diseases.

    Full Text Available The purpose of this study was to describe pathological changes of the shoulder, elbow, hip and stifle joints of 16 museum skeletons of the raccoon dog (Nyctereutes procyonoides. The subjects had been held in long-term captivity and were probably used for fur farming or research, thus allowing sufficient longevity for joint disease to become recognisable. The prevalence of disorders that include osteochondrosis, osteoarthritis and changes compatible with hip dysplasia, was surprisingly high. Other changes that reflect near-normal or mild pathological conditions, including prominent articular margins and mild bony periarticular rim, were also prevalent. Our data form a basis for comparing joint pathology of captive raccoon dogs with other mammals and also suggest that contributing roles of captivity and genetic predisposition should be explored further in non-domestic canids.

  10. Neuronal degenerative disorders studied by positron emission tomography-dopamine D1 and D2 receptors in Parkinson's disease and striato-nigral degeneration

    It is well established that patients with Parkinson's disease (PD) respond well to L-dopa therapy, but those with striato-nigral degeneration (SND) respond poorly. A possible explanation could be a loss of striatal dopamine receptors in SND. However, few attempts have been made to examine the alterations of the striatal dopamine receptors in SND. The authors studied the dopamine D1 and D2 receptors in PD (n=7), SND (N=4) and controls (n=11) by positron emission tomography (PET). [11C] N-methylspipernoe [11C] NMSP) was used as a ligand to study D2 receptors, and [11C] SCH23390 was used to study D1 receptors. The results showed that D1 and D2 receptors in PD were not significantly different from those in controls, but there was a trend toward elevated binding potential of D1 and D2 receptors in PD. The binding potential of D1 and D2 receptors in SND was significantly lower than those in controls and PD. PET images showed that the decrease of D1 and D2 receptors in SND was remarkable in the posterior putamen. PET imaging of dopamine receptors is useful for differentiating the two disorders. (author)

  11. Anaerobic prosthetic joint infection.

    Shah, Neel B; Tande, Aaron J; Patel, Robin; Berbari, Elie F

    2015-12-01

    In an effort to improve mobility and alleviate pain from degenerative and connective tissue joint disease, an increasing number of individuals are undergoing prosthetic joint replacement in the United States. Joint replacement is a highly effective intervention, resulting in improved quality of life and increased independence [1]. By 2030, it is predicted that approximately 4 million total hip and knee arthroplasties will be performed yearly in the United States [2]. One of the major complications associated with this procedure is prosthetic joint infection (PJI), occurring at a rate of 1-2% [3-7]. In 2011, the Musculoskeletal Infectious Society created a unifying definition for prosthetic joint infection [8]. The following year, the Infectious Disease Society of America published practice guidelines that focused on the diagnosis and management of PJI. These guidelines focused on the management of commonly encountered organisms associated with PJI, including staphylococci, streptococci and select aerobic Gram-negative bacteria. However, with the exception of Propionibacterium acnes, management of other anaerobic organisms was not addressed in these guidelines [1]. Although making up approximately 3-6% of PJI [9,10], anaerobic microorganisms cause devastating complications, and similar to the more common organisms associated with PJI, these bacteria also result in significant morbidity, poor outcomes and increased health-care costs. Data on diagnosis and management of anaerobic PJI is mostly derived from case reports, along with a few cohort studies [3]. There is a paucity of published data outlining factors associated with risks, diagnosis and management of anaerobic PJI. We therefore reviewed available literature on anaerobic PJI by systematically searching the PubMed database, and collected data from secondary searches to determine information on pathogenesis, demographic data, clinical features, diagnosis and management. We focused our search on five commonly encountered anaerobic organisms associated with PJI. Since anaerobic PJI has also been linked to dental procedures, we also reviewed information on the use of dental procedures and prophylaxis, when available. PMID:26341272

  12. Iron behaving badly: inappropriate iron chelation as a major contributor to the aetiology of vascular and other progressive inflammatory and degenerative diseases

    Kell Douglas B

    2009-01-01

    Full Text Available Abstract Background The production of peroxide and superoxide is an inevitable consequence of aerobic metabolism, and while these particular 'reactive oxygen species' (ROSs can exhibit a number of biological effects, they are not of themselves excessively reactive and thus they are not especially damaging at physiological concentrations. However, their reactions with poorly liganded iron species can lead to the catalytic production of the very reactive and dangerous hydroxyl radical, which is exceptionally damaging, and a major cause of chronic inflammation. Review We review the considerable and wide-ranging evidence for the involvement of this combination of (superoxide and poorly liganded iron in a large number of physiological and indeed pathological processes and inflammatory disorders, especially those involving the progressive degradation of cellular and organismal performance. These diseases share a great many similarities and thus might be considered to have a common cause (i.e. iron-catalysed free radical and especially hydroxyl radical generation. The studies reviewed include those focused on a series of cardiovascular, metabolic and neurological diseases, where iron can be found at the sites of plaques and lesions, as well as studies showing the significance of iron to aging and longevity. The effective chelation of iron by natural or synthetic ligands is thus of major physiological (and potentially therapeutic importance. As systems properties, we need to recognise that physiological observables have multiple molecular causes, and studying them in isolation leads to inconsistent patterns of apparent causality when it is the simultaneous combination of multiple factors that is responsible. This explains, for instance, the decidedly mixed effects of antioxidants that have been observed, since in some circumstances (especially the presence of poorly liganded iron molecules that are nominally antioxidants can actually act as pro-oxidants. The reduction of redox stress thus requires suitable levels of both antioxidants and effective iron chelators. Some polyphenolic antioxidants may serve both roles. Understanding the exact speciation and liganding of iron in all its states is thus crucial to separating its various pro- and anti-inflammatory activities. Redox stress, innate immunity and pro- (and some anti-inflammatory cytokines are linked in particular via signalling pathways involving NF-kappaB and p38, with the oxidative roles of iron here seemingly involved upstream of the IkappaB kinase (IKK reaction. In a number of cases it is possible to identify mechanisms by which ROSs and poorly liganded iron act synergistically and autocatalytically, leading to 'runaway' reactions that are hard to control unless one tackles multiple sites of action simultaneously. Some molecules such as statins and erythropoietin, not traditionally associated with anti-inflammatory activity, do indeed have 'pleiotropic' anti-inflammatory effects that may be of benefit here. Conclusion Overall we argue, by synthesising a widely dispersed literature, that the role of poorly liganded iron has been rather underappreciated in the past, and that in combination with peroxide and superoxide its activity underpins the behaviour of a great many physiological processes that degrade over time. Understanding these requires an integrative, systems-level approach that may lead to novel therapeutic targets.

  13. Magnetic resonance imaging evaluation of temporomandibular joint derangement in symptomatic and asymptomatic patients

    Objective was to highlight the importance of MRI in evaluation of the tempromandibular joint (TMJ). The MRI examination was performed at King Khalid University Hospital, Riyadh, Saudi Arabia with the approval from the local ethics committee, on 34 patients (68 joints) between January 2006 and November 2007, in which 10 were considered asymptomatic subjects (control). The remaining had symptoms and signs of TMJ pain or dysfunction, including limitation of movement and clicking. All our subjects were examined in both closed and open mouth position. Images were obtained by 1.5-T MRI system, in oblique sagittal plane utilizing 3 pulse sequences including T1 and T2 spinecho and spoil gradient recall sequences. The evaluation of the meniscal disc configuration and position was carried by 2 radiologists. Sixteen out of 20 joints of asymptomatic subjects were normal. In the other 2 asymptomatic subjects, the MRI showed anterior disc displacement with reduction in 3 joints and degenerative changes in 2 joints. Out of 48 asymptomatic joints, 26 (45%) joints were considered normal, while the other 22 joints showed anterior dislocation without reduction. Degenerative joint disease was also seen in 18 joints. The MRI with the use of surface coils markedly improves the delineation of internal derangement of the TMJ, therefore, it enhanced the capability of detecting certain abnormalities which proved to have a statistical significance in symptomatic patients.

  14. Variability in the MR image of the temporomandibular joint

    Although MR imaging typically shows the meniscus of the temporomandibular joint (TMJ) as a biconcave region of low signal within the joint space, there is a great deal of variability in the MR images of healthy and diseased joints. The authors examined surgically extirpated menisci (n=55), cadaver TMJs (n=16), normal volunteers (n=5), and symptomatic patients (n=25) to identify the important parameters affecting the MR image. The authors found the meniscus has a short T2 (<50 msec), which is shortened further with degenerative changes; short repetition time/echo time (TR/TE) spin-echo images depict morphology well while long TR/TE images provide more information concerning adaptive remodeling of the disc; joint space, disk and condyle relationships are most usefully demonstrated via direct sagittal images; for any given pulse sequence the histopathologic state of the joint is a key determinant of the MR image obtained

    Osteoarthritis (OA) is a degenerative joint disease with no curative treatments. Many studies have begun to demonstrate the efficacy of nutraceuticals for slowing down OA. Animal models are utilized as a compulsory step in demonstrating the protective potential of these compounds on joint health. Nevertheless, there exist a wide variety of available OA models and selecting a suitable system for evaluating the effects of a specific compound remains difficult. Here, we discuss animal studies that have investigated nutraceutical effects on OA. In particular, we highlight the large spectrum of animal models that are currently accepted for examining the OA-related effects of nutraceuticals, giving recommendations for their use.

    OBJECTIVE The Dynesys, a pedicle-based dynamic stabilization (PDS) system, was introduced to overcome the drawbacks of fusion procedures. Nevertheless, the theoretical advantages of PDS over fusion have not been clearly confirmed. The aim of this study was to compare clinical and radiological outcomes of patients who underwent PDS using the Dynesys system with those who underwent posterior lumbar interbody fusion (PLIF). METHODS The authors searched PubMed, Embase, Web of Science, and the Cochrane Database. Studies that reported outcomes of patients who underwent PDS or PLIF for the treatment of degenerative lumbar spinal disease were included. The primary efficacy end points were perioperative outcomes. The secondary efficacy end points were changes in the Oswestry Disability Index (ODI) and back and leg pain visual analog scale (VAS) scores and in range of motion (ROM) at the treated and adjacent segments. A meta-analysis was performed to calculate weighted mean differences (WMDs), 95% confidence intervals, Q statistics, and I(2) values. Forest plots were constructed for each analysis group. RESULTS Of the 274 retrieved articles, 7 (which involved 506 participants [Dynesys, 250; PLIF, 256]) met the inclusion criteria. The Dynesys group showed a competitive advantage in mean surgery duration (20.73 minutes, 95% CI 8.76-32.70 minutes), blood loss (81.87 ml, 95% CI 45.11-118.63 ml), and length of hospital stay (1.32 days, 95% CI 0.23-2.41 days). Both the Dynesys and PLIF groups experienced improved ODI and VAS scores after 2 years of follow-up. Regarding the ODI and VAS scores, no statistically significant difference was noted according to surgical procedure (ODI: WMD 0.12, 95% CI -3.48 to 3.72; back pain VAS score: WMD -0.15; 95% CI -0.56 to 0.26; leg pain VAS score: WMD -0.07; 95% CI -0.47 to 0.32). The mean ROM at the adjacent segment increased in both groups, and there was no substantial difference between them (WMD 1.13; 95% CI -0.33 to 2.59). Although the United States is the biggest market for Dynesys, no eligible study from the United States was found, and 4 of 8 enrolled studies were performed in China. The results must be interpreted with caution because of publication bias. During Dynesys implantation, surgeons have to decide the length of the spacer and cord pretension. These values are debatable and can vary according to the surgeon's experience and the patient's condition. Differences between the surgical procedures were not considered in this study. CONCLUSIONS Fusion still remains the method of choice for advanced degeneration and gross instability. However, spinal degenerative disease with or without Grade I spondylolisthesis, particularly in patients who require a quicker recovery, will likely constitute the main indication for PDS using the Dynesys system.

Reasons for low detection rates of the disease are considered. Difficulties in the laboratory and instrumental diagnosis of PPA are analyzed in detail.

  19. Ranking of MR in the diagnosis of diseases of the shoulder joint

    In a prospective study 43 patients with shoulder pain were examined by sonography and MRI. The findings were controlled by plain radiography, arthrography, and CT arthrography. Joint effusions and humeral head defects were equally identified by MR and sonography. In the diagnosis of labrum lesions, rotator cuff lesions, subacromial spurs, and synovial inflammatory disease sonography was not as accurate as MR. A special MR scoring system improved the diagnosis of an impingement syndrome. (orig.)

    2016-06-01

    This study reports the clinical effects of nano-hydroxyapatite/polyamide66 cages (n-HA/PA66 cages) and compares the clinical outcomes between n-HA/PA66 and polyetheretherketone cages (PEEK cages) for application in transforaminal lumbar interbody fusion (TLIF). A retrospective and case-control study involving 124 patients using n-HA/PA66 cages and 142 patients using PEEK cages was conducted. All patients underwent TLIF and had an average of 2-years of follow-up. The Oswestry Disability Index and Visual Analog Scale were selected to assess the pain of low back and leg, as well as neurological status. The intervertebral space height and segmental angle were also measured to estimate the radiological changes. At the 1-year and final follow-ups, the fusion and subsidence rates were evaluated. There was no significant difference between the two groups regarding clinical and radiological results. At the final follow-up, the bony fusion rate was 92.45 and 91.57 % for the n-HA/PA66 and PEEK groups, respectively, and the subsidence rate was 7.55 and 8.99 %, respectively. The study indicated that both n-HA/PA66 and PEEK cages could promote effective clinical and radiographic outcomes when used to treat degenerative lumbar diseases. The high fusion and low subsidence rates revealed that n-HA/PA66 cages could be an alternative ideal choice as the same to PEEK cages for lumbar reconstruction after TLIF. PMID:27091044

  3. Calcium pyrophosphate dihydrate crystal deposition disease presenting as a pseudotumor of the temporomandibular joint

    We report a case of a 66-year-old white woman with calcium pyrophosphate dihydrate (CPPD) crystal deposition disease. The patient related a 2-month history of swelling with tenderness over the left pre-auricular region. A CT scan suggested a synovial chondromatosis. Surgical removal was done and histologic study showed CPPD crystals. This disease rarely involves the temporomandibular joint (TMJ) and is not usually considered in the differential diagnosis. To our knowledge, only 14 cases have been reported in the literature. (orig.)

  4. WHO/IAEA joint research programme on trace elements in cardiovascular diseases

    After several years of support by WHO and IAEA for the joint research programme on trace elements in cardiovascular diseases, a consultants' meeting was held (1) to examine the present status of the programme with a view to advising on actions necessary for its completion, and (2) to advise on the form, content and timing of a final report. The meeting was attended by the invited experts and other persons. The main work of this research programme is divided, as before, between two projects, (1) on Cd, Cr, Cu, Se, Zn and other elements in relation to ischaemic heart disease, and (2) on Cd, Se and Zn in relation to arterial hypertension

  5. Computed tomography through the hip joint

    Computed tomography through the hip joint should be used only after conventional radiographs (at least a.p. views). It may provide information that is diagnostic or helpful, e.g. in bacterial infections, trauma of praearthrotic states. Indications for surgery may be obtained in the presence of inflammatory-rheumatic and degenerative hip disease, arthritic deformities and trauma, and the type of suitable operation may be indicated. The obturator internus muscle, which can be seen medial to the acetabulum on the scan, is an important diagnostic indicator where there is trauma or bacterial infection of the hip joint. The capsule of the hip joint can be visualized directly. Slice thickness of 6 mm, or less is necessary. (orig.)

  6. Comparative diagnostic imaging of the canine shoulder joint ultrasonography and radiography

    Mayer, B

    2000-01-01

    radiographically. 6 of 17 supraspinatus insertion tendinopathies (35.3 %) and 4 of 5 bicipital tendon calcifications (80 %) were detected only with ultrasonography. Radiographic findings of bony proliferations in the intertuberal groove without signs of degenerative joint disease of the shoulder joint are indicative of severe or chronic biciptal tendon disease. In many cases, the stage and severity of cartilaginous and subchondral bone lesions with osteochondritis dissecans can be determined ultrasonographically. Osteochondritis dissecans defects not seen on radiographs are occasionally visible with ultrasound, although a negative finding is not always accurate. Ultrasonography of shoulder joint disease has been applied in humans for some time. In this study, the use of radiography and ultrasonography as diagnostic imaging modalities to determine shoulder joint lesions is presented. The ultrasonographic anatomy and pathology of the shoulder joint are described. Comparative radiographic and ultrasonographic fi...

    2013-01-01

    Vitiligo is characterized by the progressive disappearance of pigment cells from skin and hair follicle. Several in vitro and in vivo studies show evidence of an altered redox status, suggesting that loss of cellular redox equilibrium might be the pathogenic mechanism in vitiligo. However, despite the numerous data supporting a pathogenic role of oxidative stress, there is still no consensus explanation underlying the oxidative stress-driven disappear of melanocytes from the epidermis. In thi...

  9. Imaging of hip joint arthroplasty

    The hip joint is the largest joint in the human body and consequently, its evaluation by diagnostic imaging is highly important. This includes imaging of hip joint arthroplasty, which is used to avoid joint immobility following a wide spectrum of diseases, such as end-stage degenerative disease, avascular necrosis of the femoral head or post-traumatic fractures. Conventional radiography is still the standard imaging modality for the evaluation of hip arthroplasty both directly following surgery and for periodical follow-up. In the majority of cases conventional radiography enables adequate assessment of early and late complications that can arise following hip arthroplasty, such as loosening, prosthetic or periprosthetic fracture, luxation, infection and soft tissue calcification. If the diagnosis cannot be established by means of radiography, advanced imaging methods such as computed tomography (CT) and magnetic resonance imaging (MRI), with or without injection of contrast media, may provide additional information. This is particularly true for the depiction of inflammatory processes. Regardless of the imaging modality used patients' clinical symptoms must also be taken into account in order to establish the correct diagnosis. (orig.)

  12. Rapid high resolution 3D imaging in MR diagnosis of diseases of the knee joint

    A new technique was developed for MR imaging of diseases of the knee joint to shorten the time required for examination. The acquisition of an isotropic 3D-dataset using a FLASH- or a FISP-sequence is the base for secondary reconstructions of planar high-resolution images (spatial resolution ?1 mm) in free orientations. Acquisition time of the 3D-dataset is 16 minutes, additional one up to five minutes are needed for image calculation. The method can image structures of the knee joint such as the cartilage, the menisci or the ligament. The advantage of the decreased examination time of about 30 minutes has been proved, but further comparative clinical studies are needed to establish the diagnostic equivalence of this method and conventional techniques.

  13. [The approach to bone and joint disease for extending the healthy life expectancy].

    Deie, Masataka; Asaeda, Makoto; Kono, Yoshifumi; Terai, Chiaki

    2014-10-01

    In Japan, the super-aged society, the difference between the healthy life expectancy and life expectancy is large, it has become a social problem. For the extension of healthy life expectancy, measures to bone and joint disease are important. Lower limb muscle strengthening is useful to decrease in pain and improvement of walking ability. Further, in order to maintain a balance function, improvement in range of motion is important. On the other hand, for patients who had joint destruction, decreased ability of exercise, muscle weakness, balance dysfunction has already occurred, it is necessary for extension of healthy life expectancy including surgical treatment. We believe that by performing the appropriate therapeutic intervention, extending healthy life expectancy would be possible. PMID:25509814

  14. Treatment of Joint Inflammatory Diseases in the Lame Backyard Chickens with NSAIDs

    M.M. Hadipour

    2011-04-01

    Full Text Available The effects of several Non-Steroidal Anti-Inflammatory Drugs (NSAIDs were determined in 200 mature backyard chickens with clinical signs of lameness. The NSAIDs, diclofenac, carprofen, ketoprofen and meloxicam with doses 0.5, 1, 2, 3 and 4 mg/kg were used in these groups, orally. Chickens were monitored on a daily basis for general condition, joint inflammation reduction and mortality. Diclofenac, carprofen and ketoprofen were associated with mortality. In contrast, there were no reported mortalities for the NSAID, meloxicam in this study. Results of the current study revealed that the meloxicam was the drug of choice with relative safety for treatment of joint inflammatory diseases in chickens.

    van Es, P.; Biswas, S. K.; Bernelot Moens, H. J.; Steenbergen, W.; Manohar, S.

    2015-03-01

    Inflammatory arthritis is often manifested in finger joints. The growth of new or withdrawal of old blood vessels can be a sensitive marker for these diseases. Photoacoustic (PA) imaging has great potential in this respect since it allows the sensitive and highly resolved visualization of blood. We systematically investigated PA imaging of finger vasculature in healthy volunteers using a newly developed PA tomographic system. We present the PA results which show excellent detail of the vasculature. Vessels with diameters ranging between 100 ?m and 1.5 mm are visible along with details of the skin, including the epidermis and the subpapillary plexus. The focus of all the studies is at the proximal and distal interphalangeal joints, and in the context of ultimately visualizing the inflamed synovial membrane in patients. This work is important in laying the foundation for detailed research into PA imaging of the phalangeal vasculature in patients suffering from rheumatoid arthritis.

  17. 18F Sodium Fluoride PET/CT in Patients with Prostate Cancer: Quantification of Normal Tissues, Benign Degenerative Lesions, and Malignant Lesions

    Oldan, Jorge D.; Hawkins, A. Stewart; Chin, Bennett B.

    2016-01-01

    Understanding the range and variability of normal, benign degenerative, and malignant 18F sodium fluoride (18F NaF) positron emission tomography/computed tomography (PET/CT) uptake is important in influencing clinical interpretation. Further, it is essential for the development of realistic semiautomated quantification techniques and simulation models. The purpose of this study is to determine the range of these values in a clinically relevant patient population with prostate cancer. 18F NaF PET/CT scans were analyzed in patients with prostate cancer (n = 47) referred for evaluation of bone metastases. Mean and maximum standardized uptake values [SUVs (SUVmean and SUVmax)] were made in normal background regions (n = 470) including soft tissues (liver, aorta, bladder, adipose, brain, and paraspinal muscle) and osseous structures (T12 vertebral body, femoral diaphyseal cortex, femoral head medullary space, and ribs). Degenerative joint disease (DJD; n = 281) and bone metastases (n = 159) were identified and quantified by an experienced reader using all scan information including coregistered CT. For normal bone regions, the highest 18F NaF PET SUVmean occurred in T12 (6.8 ± 1.4) and it also showed the lowest coefficient of variation (cv = 21%). For normal soft tissues, paraspinal muscles showed very low SUVmean (0.70 ± 0.11) and also showed the lowest variability (cv = 16%). Average SUVmean in metastatic lesions is higher than uptake in benign degenerative lesions but values showed a wide variance and overlapping values (16.3 ± 13 vs 11.1 ± 3.8; P PET uptake values for prostate cancer patients in normal background, benign degenerative disease, and osseous metastases are comparable to those reported for a general population with a wide variety of diagnoses. These normal ranges, specifically for prostate cancer patients, will aid in clinical interpretation and also help to establish the basis of normal limits in a semiautomated data analysis algorithm.

  18. Hip and pelvis diseases on lumbar AP radiographs including both hip joints

    To determine the frequency of diseases of the hip and pelvis, as seen of plain radiography of the lumbar spine in patients with suspicious lumbar disease, and to evaluate the methods used of lumbar spine radiography in Korea. Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1252 patients, taken using 14' x 17' film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. In 15 patients (1.2%), the radiographs revealed hip or pelvic lesions, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesions in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 of the 20 hospitals which responded, 14' x 17' film was being used for lumbar radiography, while in the other nine, film size was smaller. Plain radiography of the lumbar spine including both hip joints, may be a useful was to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis

  20. Degenerative spine disorders in the context of clinical findings

    Hardly any other structure in the human body is held responsible for so many complaints, pain, and costs as the spine and its degenerative disorders. In the following article, the role of imaging procedures in diagnosing disorders of the spine is presented. Due to the fact that disk herniation represents the most frequent cause for degenerative disorders the anatomy of the intervertebral disk and the pathology of the entities that can cause diseases of the disks are described. In particular, the authors focus on the significance of radiological findings with respect to patient history, subjective symptoms, and objective clinical findings. In addition to presenting the technical procedures and their indications and contraindications also practical tips and tricks in conducting these examinations are presented in this paper

  3. Rheumatoid arthritis-celiac disease relationship: joints get that gut feeling.

    Lerner, Aaron; Matthias, Torsten

    2015-11-01

    Rheumatoid arthritis (RA) and celiac disease (CD) belong to the autoimmune disease family. Despite being separate entities they share multiple aspects. Epidemiologically they share comparable incidence environmental influences, associated antibodies and a recent incidental surge. They differ in their HLA pre-dispositions and specific predictive and diagnostic biomarkers. At the clinical level, celiac disease exhibits extra-intestinal rheumatic manifestations and RA gastrointestinal ones. Small bowel pathology exists in rheumatic patients. A trend towards responsiveness to a gluten free diet has been observed, ameliorating celiac rheumatic manifestations, whereas dietary interventions for rheumatoid arthritis remain controversial. Pathophysiologically, both diseases are mediated by endogenous enzymes in the target organs. The infectious, dysbiotic and increased intestinal permeability theories, as drivers of the autoimmune cascade, apply to both diseases. Contrary to their specific HLA pre-disposition, the diseases share multiple non-HLA loci. Those genes are crucial for activation and regulation of adaptive and innate immunity. Recently, light was shed on the interaction between host genetics and microbiota composition in relation to CD and RA susceptibility, connecting bugs and us and autoimmunity. A better understanding of the above mentioned similarities in the gut-joint inter-relationship, may elucidate additional facets in the mosaic of autoimmunity, relating CD to RA. PMID:26190704

  4. Nuclear Medicine in Diagnosis and Therapy of Bone and Joint Diseases

    Concerning bone and joint diseases therapy of rheumatic synovitis (radiosynoviorthesis) was introduced in 1952 before clinically relevant diagnostic procedures were developed. Radionuclides of Sr and later on 99mTc phosphonates then started the wide use of bone scintigraphy since > 30 years. The diagnostic methods have an excellent sensitivity for detection of local abnormalities of bone metabolism, the specificity of such studies, however, is low. Modifications of the technique (3-phase-bone-scintigraphy, pinhole collimators, ROI-technique), increasing knowledge of pathological scan patterns and introduction of other radionuclide studies (67Ga, 201Tl, inflammation scans with 99mTc-leukocytes or 99mTc-HIG) as well as 18FDG-PET have increased the specificity significantly in recent years and improvements of imaging systems (SPECT) also increased the accuracy of diagnostic methods in diseases of bone and joints. Therapy of such diseases has made considerable progress: inflamed, swollen joints can effectively be treated with 90Y-, 186Re, 169Er-colloids or with 165Dy-particles by radiosynoviorthesis. Severe pain due to disseminated bone metastases of cancer or polyarthritis can be controlled by radionuclide therapy with 89Sr, 153Sm-EDTMP, 186Re- or 188Re-HEDP and possibly 117mSn-DTPA with an acceptable risk of myelodepression. Possibilities, technical details and limitations of radionuclide applications for diagnostic and therapeutic purposes must be considered if optimal benefit for individual patients should be achieved. Overall Nuclear Medicine can become an essential element in management of bone and joint diseases. The relationship of Nuclear Medicine to bone and joint pathology is peculiar: In 1952 treatment of rheumatic synovitis by radiosynoviorthesis with 198Au Colloid was started by Fellinger and Schmid before diagnostic approaches to bone pathology existed. Bone scintigraphy was introduced only in 1961 using 85Sr but obviously the unfavourable radiation characteristics of this radionuclide limited it's broad application and 87mSr did not improve this situation. Only when 99mTc phosphonates were developed by Subramanian the importance of bone scintigraphy became apparent: The excellent imaging properties of these radiotracers showed, that abnormal bone metabolism could be visualized even before morphological alterations in the skeleton become visible on radiographies or even CT-scans. Moreover, proposals made earlier to use 32P or 89Sr for palliation of pain in patients with disseminated skeletal metastases were picked up again and led also to other radiopharmaceuticals (186Re-HEDP, 153Sm-EDTMP, 117mSn-DTPA) which are applied today for the same purpose with very good success. Therefore Nuclear Medicine today has a broad program for diagnostic and therapeutic approaches to diseases of bone and joints. In bone scanning the high sensitivity led to inclusion of this method for routine staging and re-staging programs in a variety of cancer forms which have a trend to develop bone metastases (e.g. breast, lung, prostate, melanoma) but the low specificity of abnormal patterns on such scans can impair the diagnostic value of the technique. To increase specificity and to define inflammatory lesions, radiotracers used for ''inflammation scanning'' were introduced such as labeled granulocytes, 99mTc Human Immunoglobuline and others but also a simple modification of bone scanning - triple phase bone scintigraphy - was used. Recently the excellent properties of 18F for PET of the skeleton were rediscovered again and emission CT scanning - possibly with overlay with transmission CT or MRT pictures - can enhance the diagnostic impact of radionuclide bone studies.

    We present the main MR features of cystic lesions around the knee joint. Popliteal cysts are the most frequently seen. The usually result from extrusion of joint fluid into the gastrocnemio-semimembranosus bursa but they can have an atypical location or extension. They are most often due to a meniscal, ligamentous, degenerative or inflammatory joint disease responsible for a chronic joint effusion. Meniscal cysts are always associated with a horizontal tear. Medial meniscal cysts are larger and can extend far from the joint. Bursitis occur as a result of inflammation or infection of a bursa. Their location is stereotyped and they do not communicate with the knee joint. Ganglion cysts or ganglia are benign cystic lesions which can affect peri-articular tissues as well as subchondral bone or cruciate ligaments. MRI is now a simple and noninvasive way of obtaining etiologic diagnosis and guiding therapy. (authors). 46 refs.

  7. Local Gene Transfer of OPG Prevents Joint Damage and Disease Progression in Collagen-Induced Arthritis

    Zhang, Qingguo; Gong, Weiming; Ning, Bin; Nie, Lin; Wooley, Paul H.

    2013-01-01

    This study examined the influence of osteoprotegerin (OPG) gene transfer on a murine collagen-induced arthritis model. A single periarticular injection of AAV-OPG or AAV-LacZ on the arthritic paw successfully incorporated the exogenous gene to the local tissue and resulted in marked transgene expression in the joint homogenate for at least three weeks. Clinical disease scores were significantly improved in OPG treated mice starting at 28-day post-treatment (P < 0.05). Histological assessment demonstrated that OPG gene transfer dramatically protected mice from erosive joint changes compared with LacZ controls (P < 0.05), although treatment appeared less effective on the local inflammatory progress. MicroCT data suggested significant protection against subchondral bone mineral density changes in OPG treated CIA mice. Interestingly, mRNA expressions of IFN-g and MMP3 were noticeably diminished following OPG gene transfer. Overall, gene transfer of OPG effectively inhibited the arthritis-associated periarticular bone erosion and preserved the architecture of arthritic joints, and the study provides evidence that the cartilage protection of the OPG gene therapy may be associated with the down-regulation of MMP3 expression.

    Full Text Available We report a case of a Calcium pyrophosphate dihydrate deposition disease (CPPD presenting as a mass in the parotid and temporomandibular joint (TMJ that simulated a parotid tumor. A 35 year-old man presented with pain in the left ear area. A CT Scan of the area showed a large, calcified mass surrounding the left condylar head, and extending into the infratemporal fossa. FNA of the mass showed birefringent crystals, most of which were rhomboid with occasional ones being needle shaped, embedded in an amorphous pink substance. Scanning electron microscopy (SEM with energy dispersive x-ray spectroscopy (EDS of these crystals showed peaks corresponding to calcium and phosphorus. SEM/EDS is a rapid method of diagnosing calcium pyrophosphate dihydrate deposition disease (CPPD and an alternative to more commonly used method of special staining of cell block sections coupled with polarizing microscopy.

    Full Text Available Abstract Objectives The aims of this study were to model jointly the incidence rates of six smoking related cancers in the Yorkshire region of England, to explore the patterns of spatial correlation amongst them, and to estimate the relative weight of smoking and other shared risk factors for the relevant disease sites, both before and after adjustment for socioeconomic background (SEB. Methods Data on the incidence of oesophagus, stomach, pancreas, lung, kidney, and bladder cancers between 1983 and 2003 were extracted from the Northern & Yorkshire Cancer Registry database for the 532 electoral wards in the Yorkshire region. Using postcode of residence, each case was assigned an area-based measure of SEB using the Townsend index. Standardised incidence ratios (SIRs were calculated for each cancer site and their correlations investigated. The joint analysis of the spatial variation in incidence used a Bayesian shared-component model. Three components were included to represent differences in smoking (for all six sites, bodyweight/obesity (for oesophagus, pancreas and kidney cancers and diet/alcohol consumption (for oesophagus and stomach cancers. Results The incidence of cancers of the oesophagus, pancreas, kidney, and bladder was relatively evenly distributed across the region. The incidence of stomach and lung cancers was more clustered around the urban areas in the south of the region, and these two cancers were significantly associated with higher levels of area deprivation. The incidence of lung cancer was most impacted by adjustment for SEB, with the rural/urban split becoming less apparent. The component representing smoking had a larger effect on cancer incidence in the eastern part of the region. The effects of the other two components were small and disappeared after adjustment for SEB. Conclusion This study demonstrates the feasibility of joint disease modelling using data from six cancer sites. Incidence estimates are more precise than those obtained without smoothing. This methodology may be an important tool to help authorities evaluate healthcare system performance and the impact of policies.

  11. Hip and pelvis diseases on lumbar AP radiographs including both hip joints

    To determine the frequency of disease, and to evaluate the methods used for lumbar spine radiography in Korea. Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1215 patients, taken using 14x17 inch film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. In 15 patients (1.2%), the radiographs revealed hip or pelvic lesion, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesion in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 or the 20 hospitals which responded, 14x17film was being used for lumbar radiography, while in the other nine, film size was smaller. Plain radiography of the lumbar spine including both hip joints, may be a useful way to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis

  13. Enculturation and the Degenerative Principle

    Daniel Washburn

    2008-12-01

    Full Text Available The model of enculturation I propose operates with a claim that individuals are intrinsically idiosyncratic. Support for individual idiosyncrasy begins at the level of neurons and goes on to encompass inter-individual phenomena. I draw on cognitive and social theory to support my position. In particular I consider the work of neurologistGerald Edelman (2004 and his “theory of neuronal group selection” (TNGS and Sahlins(2000 and his theory of culture. The model of culture presented here is designed to account for the phenomenon of individual idiosyncrasy. For this reason, culture is necessarily presented as a process - and I am calling the process “enculturation.” The cognitive phenomena that allow language and signs to be shared between people are, within each individual, constantly changing via idiosyncratic neuronal firing patternsand via the incorporation of new experience and altered memory. The concept of memory is discussed in relation the model of enculturation. The Durkheimian position, that social scientists should focus on collective representations and avoid makingsocial claims based on the operation of individual minds (Durkheim, 1915:15-16;1952:213 is given consideration. Cognitive research is introduced to suggest links between experience and memory (such as Edelman’s concept of the “remembered present” and to establish the function of “the degenerative principle”. The work of Libet (2004 is utilized to suggest that conscious awarenesses are preceded byunconscious processes (i.e., processes outside reflective consciousness, and as such we are forced to conclude that unconscious processes initiate our conscious experiences. This raises questions of agency and free will. It is suggested that theprocess of cognitive association leads to novelty as a result of the instability of recurrent memory and the intrinsic idiosyncrasy of neurons. Enculturation then, can be seen as the activity of association as augmented by intrinsically idiosyncratic phenomena.Parallels are drawn between Bakhtin’s dialogic principle and the enculturation model.The concluding section suggests avenues for the future.

  14. SHOULD DISEASE-MODIFYING THERAPY BE STOPPED IN PATIENTS WITH RHEUMATOID ARTHRITIS BEFORE ENDOPROSTHETIC JOINT REPLACEMENT?

    2011-06-01

    Full Text Available Objective: to analyze disease activity, functional state, quality of life (QL, and the frequency of infectious complications in methotrexate (MT – or leflunomide (LF-treated patients with rheumatoid arthritis (RA who had undergone endoprosthetic replacement of the large joints of the lower limbs. Subjects and methods. One hundred and fourteen patients with RA who had undergone endoprosthetic replacement of the knee and hip joints were divided into 3 groups: 1 36 patients who continuously received MT or LF in the perioperative period; 2 42 patients who dis- continued MT or LF 2 and 4 weeks, respectively, prior to surgery; 3 36 patients who took no disease-modifying anti-rheumatic drugs (DMARDs within 12 months before surgery. Disease activity was estimated by the DAS28 index. QL was determined using the EQ-5D questionnaire and functional capacity was estimated by the HAQ index. Results and discussion. In all the groups, there was a preponderance of patients with moderate RA activity (more than 60%. In Groups 1 and 2, the mean dose of MT was about 10 mg weekly and that of LF was 20 mg daily. The use duration of glucocorticoids (GC and their doses were comparable in all the groups. Twelve months after surgery, DAS28 significantly reduced from 4.22±1.08 to 3.58±1.07 months in Group 1 (p = 0.01; in Group 2, the decrease was insignificant: from 4.17±1.17 to 3.80±1.15 (p > 005; in Group 3, RA activity remained as before. All the groups achieved 50% functional improvement; better results were obtained in the group of patients who continued to use DMARDs in the perioperative period (∆HAQ=-0.67. The difference in the Eq-5D index corresponded to a moderate QL improvement: ∆EQ-5D = 0.28, 0.29, and 0.31 in Groups 1, 2, and 3, respectively (p < 0.05. There were no significant group differences. Deep infection in the endoprosthetic replacement area was detected in 2.8, 2.4, and 8.3% of cases, respectively (p > 005. Conclusion. Continuous use of MT and LF leads to a reduction in total disease activity and to functional improvement in patients with RA after endoprosthetic joint replacement, without increasing the frequency of infectious complications.

    Full Text Available One of the most menacing complications of large joint total endoprosthesis (TE in patients with rheumatic diseases(RD is the development of periprosthetic infection (PI, progression of which may give rise not only to limb loss, butalso death. At the same time, early diagnosis and adequate surgical care make it possible not only to arrest the infectiousprocess, but also to preserve an implanted joint.Objective: to define criteria for the diagnosis, prevention, and treatment of PI after hip and knee joint (HJ and KJ TEin patients with RD.Subjects and methods. In 2009 to 2013, 654 KJ and 549 HJ TE was performed in the V.A. Nasonova Research Instituteof Rheumatology performed KJ (n = 654 and HJ (n = 549 joint ERs.Results and discussion. PI developed in 12 (3.63% and 8 (2.95% patients after KJ and HJ ER, respectively. Early,delayed, and late PI was seen in 11, 6, and 3 patients, respectively. Eleven patients with early PI underwent joint revision/debridement with preservation of an endoprosthesis and replacement of HJ endoprosthetic inserts and heads.The operations were completed with the collagen hemobiotics being left in the wound and its drainage. Systemicantibiotic therapy was used for 46 weeks. No recurrent infection was observed in 9 cases. Two patients underwentresurgery, by setting suction-irrigation systems. Nine patients with delayed or late PI had the following operations:A single-stage revision operation (the endoprosthesis was removed and a new one was implanted was performed intwo cases of stable endoprosthetic components and accurately verified low-virulent microorganisms susceptible to certainantibiotics. It was imperative to use cement with an antibiotic, collagen hemobiotics, and systemic antibiotic therapyfor 6 weeks. The other 7 patients with unstable endoprosthetic components underwent two-stage revision: Stage 1,endoprosthetic removal and antibiotic-loaded spacer implantation; 6-12 weeks after postoperative wound healing,6 patients underwent Stage 2, removal of the spacer and implantation of a new endoprosthesis. Following Stage 1, onefemale patient developed generalized infection and, because of her advanced age and comorbidities, underwent amputationfollowed by exoprosthetic replacement.Conclusion. The practical application of the current diagnostic criteria allowed to reveal early slowly progressive PI, perform early surgical treatmentwithout endoprosthetic removal in 11 patients, and prevent recurrent infection in 81.8% of the patients. The described treatment policy for PI turnedout to be effective and prevented recurrent infection in 70% of the patients during 1 to 5 years.

  16. MTADM: The new Joint Master Programme in Transboundary Animal Disease Management for Eastern Africa

    Full text: New Partnership for Africa's Development (NEPAD) flagship Comprehensive Africa Agriculture Development Programme (CAADP). Focus is on livestock for trade and export. Better policies, institutions, regulatory framework and technologies are sought for livestock production and management and delivery of veterinary services and disease control. The disease status of African countries places the pivotal constraints on trade possibilities. Animal health standards imposed by importing countries for international, regional or bi-lateral trade, and through the World Trade Organisation's (WTO) Sanitary and Phytosanitary (SPS) agreement must be met. 12 of the 15 most important transboundary animal diseases persist in Africa. Disease control under SPS, entailing new standards, regulations and technologies, can and is not be covered by conventional veterinary training. This specialist area of its own has to be addressed in a specialised postgraduate course for young personnel already involved and responsible for public, private and hybrid animal disease control services. Ambitious visions of a new African livestock sector with changed focus on production, disease, trade, marketing, organisation, delivery and internationality are only realistic with newly trained animal disease control personnel. To target these issues at the academic level the Addis Ababa University / Ethiopia with universities of 3 regional partner countries (Kenya, Uganda, Sudan) and the Freie Universitaet Berlin, Germany, successfully applied for a grant to establish a Joint Master Course in Transboundary Animal Disease Management (MTADM) for Africa. The 3-year project is funded under the EU - EDULINK Programme of the 9th European Development Funds (EDF) as from 2008 to 2010. Currently, preparatory work is ongoing on the final technical details of the MTADM Course. The overall objective of the programme is to strengthen the capacity of national veterinary services in Africa to control and manage trans-boundary and epidemic diseases more effectively in a regional concerted action so as to (a) contributing towards developing or expanding exports markets and trade for animals and animal products and, (b) improve in the longer run the livelihood of livestock keepers as well as consumers demands on quality and safety of animal products. The specific objectives are to build human resource capacity by producing an effective cadre of professionals in regional / trans-boundary animal disease control and management and to strengthen the regional network of the veterinary faculties of the participating African countries. This is to be achieved through: - the development of an innovative and state-of-the-art curriculum for the Joint MTAD Programme, - a first MTADM course executed at Addis Ababa University/Ethiopia, Freie Universitaet Berlin, and the African home country of the participant, - a second MTADM Course prepared and ready to be launched at a second Regional Partner University, and - a first group of at least 15 graduates being highly qualified and ready to take up meaningful employment in the animal disease control sectors. The MTADM Master Course is delivered as cross-border 'sandwich' programme, in modular form (EU system of ECTS credits; 120 ECTS total) with the Master Thesis carried out as a field study project under guidance of the partner universities in the African region. The MTADM Master Programme is directed towards young early-career professionals already involved in animal disease and sanitary control activities but who identified academic master-level training needs for innovative tools and methods in transboundary animal disease management to advance their career. The Course Announcement will be circulated early 2009 and applications are welcome before October 2009; qualified candidates may apply for scholarships provided by German, regional and international organisations.

  17. Morphodynamic study of haemophilic joint diseases with the scintillation camera and a whole-body scintigraphy system

    Joint lesions in haemophilics were studied with a new whole-body scintigraphic system which combines the scintillation camera and an automatic travelling table. The results obtained are compared with clinical and radiographic data and an attempt is made to explain the mechanism of tracer uptake (sup(99m)Tc-tin-pyrophosphate) on the lesions. This system is found to offer great advantages over traditional systems for the study of haemophilic joint diseases since all the joints affected can be estimated in a very short time, a very important point in following the progress of the lesion, preventing relapses and checking the efficiency of the treatment

  18. Radiographical analysis concernig the etiology of degenerative spondylolisthesis of the lumbar spine

    The purpose of this article is to evaluate radiographically degenerative spondylolisthesis of the lumbar spine, with the main focus on the configuration of posterior elements. A comparative study between 49 cases of degenerative spondylolisthesis and 99 cases of other lumbar disorders was performed, using 13 radiographical parameters. The results clearly indicate the posterior elements of degenerative spondylolisthesis shifted horizontally and sagittally to allow slipping. This was due to the weak bony hook mechanism. Furthermore, almost all facet joints were morphologically classified as sagittal or intermediate type. Another meaningful difference was the alignment of the lumbar spine which showed an increase in both lordosis and lumbosacral angle. On the other hand, the level of Jacoby's line was almost the same in both groups. These characteristic configurations could be the cause of listhesis, although further study should be carried out to elucidate whether they are present at the non-listhetic stage. (author)

    Kashin-Beck disease (KBD) is an endemic degenerative osteoarthritis. Death of cartilage and growth plate is the pathologic feature; therefore, KBD involves skeletal deformity and often results in osteoarthritis. Deficiency of selenium, high humic acid levels in water, and fungi on storage gains are considered the cause of KBD. The most frequently involved joints are ankles, knees, wrists, and elbows and symptoms are pain and limited motions of those joints. The main treatments for KBD are reh...

  20. Scintigraphy by Means of Radioisotopes of Short Half-Life for Diagnosing Diseases of the Joints

    Persons suffering from articular diseases exhibit an increase in vascularization associated with a concomitant inflammatory process. This hyper-vascularization can be visualized in cases of rheumatoid arthritis by means of radiotracer scanning of the vascular compartment, as indicated by Maxfield in 1965. The authors present the results of a study of 107 persons suffering from various articular conditions. The study was based on radioisotope scanning with 99mTc and 113mIn. For this purpose they made use of commercial apparatus with a .5-in. crystal and an 85-hole focussed collimator. They applied 6-10 mCi of 99mTc in the form of sodium pertechnetate and 8-10 mCi as indium chloride (adjusted to pH 3.5), both administered intravenously at 24-hour intervals. Different scintigraphic images were observed for each of the radioisotopes, the degree of concentration not being identical for a given joint. The procedure was useful for the early diagnosis of articular lesions and in some cases for carrying out differential diagnosis. It is also indicated that the increase in vascular permeability would afford the most satisfactory explanation for the increaised radioactivity in the joints when 99mTc is used as pertechnetate, even though other factors might exist apart from the increase in vascularization, which was not satisfactorily shown when 113mIn was used.

  2. Percutaneous transluminal angioplasty of chronic arterial occlusive disease below the knee joint

    The purpose of this study was to determine the safety and efficacy of the percutaneous transluminal angioplasty(PTA) in patients with chronic arterial occlusive disease below the knee joint. We retrospectively analyzed the results of 36 procedures in 16 patients. There were 15 men and one woman, aged 57-75 years(mean, 62 years). Indications were disabling claudication (SVS/ISCVS grade 1, category 3) in five cases, rest pain(grade 2, category 4) in three cases, and non-healing ulceration or gangrene(grade3, category 5) in eight cases. PTA was performed by using small vessel balloon catheter of 2-4 mm and 3 mm monorail balloon catheter in tibioperoneal vessels and 5-6 mm balloon catheter in distal popliteal artery and tibioperoneal trunk. Combined thrombolytic therapy with Urokinase was performed in 14 patients. Involved infrapopliteal vessels were four distal popliteal arteries, 15 tibioperoneal trunks, six anterior tibial arteries, five posterior tibial arteries, and seven peroneal arteries. Technical success was determined when post-PTA angiogram showed less than 30% of residual stenosis. Clinical success was defined as improvement of clinical symptoms, such as disappearance of claudication or rest pain, and healing of ulcereation. Technical success was achieved in 30 of 36 arteries(83%). Clinical success was achieved in 12 of 16 patients(75%) at an average follow-up of 13.3 months(range, 2-46 months). Clinical success rate was 100% in grade 1 category 3 patients, 67% in grade 2 category 4 patients, and 63% in grade 3 category 5 patients. Complication included two distal emboli, one vessel rupture, one vessel thrombosis, and one occluding intimal flap. PTA was an effective method for treatment of chronic arterial occlusive disease below the knee joint and considered as the procedure of first choice. Severe claudicant(grade1) should be included in the indication of the tibioperoneal PTA

  4. Common surgical complications in degenerative spinal surgery

    Elias C Papadopoulos

    2013-01-01

    Full Text Available The rapid growth of spine degenerative surgery has led to unrelenting efforts to define and prevent possible complications, the incidence of which is probably higher than that reported and varies according to the region of the spine involved (cervical and thoracolumbar and the severity of the surgery. Several issues are becoming progressively clearer, such as complication rates in primary versus revision spinal surgery, complications in the elderly, the contribution of minimally invasive surgery to the reduction of complication rate. In this paper the most common surgical complications in degenerative spinal surgery are outlined and discussed.

  7. The twenty-four/four hour ratio (T/F ratio) of Tc-99m MDP uptake in patients with bone metastases and degenerative changes

    Normal and metastatic bone differ in their histological structure. Normal bone is mainly lamellar while metastatic bone formation is made in a large part out of new woven bone. The woven bone has a much larger surface area than the more stable lamellar bone and it is lined with metabolically active osteoblasts. The crystalline structures in the woven bone are smaller and have a larger surface area available for absorption. Uptake of bone seeking radiopharmaceuticals continues in new woven bone longer than in the lamellar bone. Bone scintigraphy was performed in 89 patients at four hours and 24 hours using a digital camera. The lesion to non lesion (L/N) ratio was determined using the camera computer. The T/F ratio was calculated: T/F=((L/N)-24)/((L/N)-4). Three groups were investigated. In 15 patients with metastatic bone carcinoma, T/F ratio was 1.46 +- 0.4. In 47 patients with degenerative joint disease the T/F ratio was 1.05 +- 0.06. In 27 patients with treated metastatic bone carcinoma the T/F ratio was 1.12 +- 0.13. The T/F ratio is significantly (p<0.001) different in patients with metastases compared to patients with benign degenerative disease. Chemotherapeutic and hormonal treatment cause significant (p<0.001) reduction in the T/F ratio. The T/F ratio may have a potential in differentiating degenerative from neoplastic diseases and in the evaluation of patients with bone metastases undergoing treatment

    Full Text Available One of the most menacing complications of large joint total endoprosthesis (TE in patients with rheumatic diseases (RD is the development of periprosthetic infection (PI, progression of which may give rise not only to limb loss, but also death. At the same time, early diagnosis and adequate surgical care make it possible not only to arrest the infectious process, but also to preserve an implanted joint.Objective: to define criteria for the diagnosis, prevention, and treatment of PI after hip and knee joint (HJ and KJ TE in patients with RD.Subjects and methods. In 2009 to 2013, 654 KJ and 549 HJ TE was performed in the V.A. Nasonova Research Instituteof Rheumatology performed KJ (n = 654 and HJ (n = 549 joint ERs.Results and discussion. PI developed in 12 (3.63% and 8 (2.95% patients after KJ and HJ ER, respectively. Early, delayed, and late PI was seen in 11, 6, and 3 patients, respectively. Eleven patients with early PI underwent joint revision/ debridement with preservation of an endoprosthesis and replacement of HJ endoprosthetic inserts and heads. The operations were completed with the collagen hemobiotics being left in the wound and its drainage. Systemic antibiotic therapy was used for 4–6 weeks. No recurrent infection was observed in 9 cases. Two patients underwentresurgery, by setting suction-irrigation systems. Nine patients with delayed or late PI had the following operations: A single-stage revision operation (the endoprosthesis was removed and a new one was implanted was performed in two cases of stable endoprosthetic components and accurately verified low-virulent microorganisms susceptible to certain antibiotics. It was imperative to use cement with an antibiotic, collagen hemobiotics, and systemic antibiotic therapy for 6 weeks. The other 7 patients with unstable endoprosthetic components underwent two-stage revision: Stage 1, endoprosthetic removal and antibiotic-loaded spacer implantation; 6-12 weeks after postoperative wound healing, 6 patients underwent Stage 2, removal of the spacer and implantation of a new endoprosthesis. Following Stage 1, one female patient developed generalized infection and, because of her advanced age and comorbidities, underwent amputation followed by exoprosthetic replacement.Conclusion. The practical application of the current diagnostic criteria allowed to reveal early slowly progressive PI, perform early surgical treatment without endoprosthetic removal in 11 patients, and prevent recurrent infection in 81.8% of the patients. The described treatment policy for PI turned out to be effective and prevented recurrent infection in 70% of the patients during 1 to 5 years.

  10. Comparative diagnostic imaging of the canine shoulder joint: ultrasonography and radiography

    Ultrasonography of shoulder joint disease has been applied in humans for some time. In this study, the use of radiography and ultrasonography as diagnostic imaging modalities to determine shoulder joint lesions is presented. The ultrasonographic anatomy and pathology of the shoulder joint are described. Comparative radiographic and ultrasonographic findings in 67 dogs with front limb lameness and/or radiographically visible shoulder joint lesions are presented. Shoulder joint lesions include insertion tendinopathies of the supra- and infraspinatus muscles, distension of the subtendinous bursa of the infraspinatus muscle, bicipital tendinopathies, such as tendovaginitis, calcifications, partial and complete rupture, and avulsion fractures at the supraglenoid tubercle, osteochondritis dissecans, degenerative joint disease, bony proliferations in the intertuberal groove, and neoplasia of bones and soft-tissues. Ultrasonographic diagnosis of tendon abnormalities and other soft tissue lesions is a necessary supplemental examination to radiographs, which should always be the basis for orthopedic diagnostic imaging. When using both imaging techniques, the exact location of radio-opaque mineralizations can be determined and a more accurate diagnosis made. The ultrasonographic appearance of an infraspinatus muscle insertion tendinopathy in conjunction with distension of the subtendinous bursa is reported for the first time. Low-density calcifications are not visible radiographically. 6 of 17 supraspinatus insertion tendinopathies (35.3 %) and 4 of 5 bicipital tendon calcifications (80 %) were detected only with ultrasonography. Radiographic findings of bony proliferations in the intertuberal groove without signs of degenerative joint disease of the shoulder joint are indicative of severe or chronic biciptal tendon disease. In many cases, the stage and severity of cartilaginous and subchondral bone lesions with osteochondritis dissecans can be determined ultrasonographically. Osteochondritis dissecans defects not seen on radiographs are occasionally visible with ultrasound, although a negative finding is not always accurate. (author)

  14. [Sacroiliac joints: osteoarthritis or arthritis].

    García Díez, Ana Isabel; Tomás Batllé, Xavier; Pomés Talló, Jaume; Amo Conill, Montserrat Del

    2009-02-01

    One of the most challenging aspects of treating the sacroiliac joint (SIJ) pain is the complexity of diagnosis. Imaging methods have gained importance for the diagnosis of SIJ diseases. CT and MR exams had equal efficacy superior to radiography in staging structural changes in the SIJ due to osteoarthritis or sacroiliitis. The diagnosis of spondyloarthropaty can be delayed for several years using certain radiography studies. MR imaging reveal early cartilage changes and active inflammatory changes in the subchondral bone and surrounding ligaments in spondyloarthropaties, as well as subperiosteal and transcapsular yuxtaarticular infiltrations characteristic of septic sacroiliitis, which could not be found by either CT of radiography. T1-WI with fat suppression (FS) and STIR images improve the demonstration of erosions and inflammatory changes respectively, on MR studies. Additional T1-FS after i.v. contrast has proven valuable in demonstrating the extension of inflammatory changes and abscesses in septic sacroiliitis, and in spondyloartropaties may be useful although this is debatable. Scintigraphy gives high sensibility only in early inflammatory changes and low specificity for the diagnosis of sacroiliitis due to high bone turnover in the SIJ, although specific radioprobes are useful in confirming the septic etiology and evaluating additional foci. This complex joint of very limited mobility shows a lot of structural variations and some anatomical degenerative changes due to age, which are necessary to know to an adequate image interpretation and diagnosis of disease.

  16. Development of Modulators Against Degenerative Aging Using Radiation Fusion Technology

    In this study, we selected final 20 biomarkers for the degenerative aging to develop radiation aging modeling, and validated a few of selected markers to utilize them in the screening of aging modulators. To select the biomarkers of the degenerative aging, 4 categories of aging-related markers (immune/hematopoiesis, oxidative damage, signaling molecule, lipid metabolism) were comparatively analyzed in irradiated and normally aged biosystems (cell lines or mice). In result, most of the biomarkers showed similar changes by irradiation and normal aging. Regarding the immune/hematopoiesis, the decline of immune cell functions (lymphocyte, NK cell) and Th1/Th2 imbalance, and decreased antigen-presenting of dendritic cells were observed and 10 biomarkers were selected in this category. mtDNA deletion was selected for the oxidative damage marker, 6 biomarkers including p21 and p-FOXO3a for signaling molecule biomarkers, and 3 biomarkers including the adipose tissue weight were selected for lipid metabolism. In addition, the various radiation application conditions by single/factionated irradiation and the periods after the irradiation were investigated for the optimal induction of changes of biomarker, which revealed that total 5Gy of 10 or more fractionated irradiations and 4 months or greather period were observed to be optimal. To found the basis for the screening of natural aging modulators, some selected aging biomarkers were validated by their inhibition by well-known natural agents (EGCG, HemoHIM, etc) in aged cell or mouse model. Additionally, by evaluating the reductive efficacy of 5 natural agents on the degeneration of skin and reproductive organs induced by radiation and chemicals (cyclophosphamide, etc), we established the base for the screening of degenerative diseases by various factors

  18. Hinged distraction of the hip joint in the treatment of Perthes disease: evaluation at skeletal maturity.

    Laklouk, Mohamed Abdel-Rehim; Hosny, Gamal Ahmed

    2012-09-01

    The aim of this work is to determine the effect of this type of treatment on the shape of the femoral head, the range of motion (ROM), radiological changes in the femoral head, and the prognosis of Perthes disease at skeletal maturity. From 1998 to 2007, 53 patients with Perthes disease were treated with a combination of soft tissue release and joint distraction with a hinged monolateral external fixator in 32 patients and by Ilizarov external fixator in 21 patients. Nineteen of our 53 patients attained skeletal maturity and were evaluated in our study. This study included 15 boys and four girls, mean age at surgery 9.3 years (range 7.2-13.1), and mean age at the last follow-up 17.4 years (range 14.9-21.3). The duration of symptoms varied from a period of 6 to 60 months before the operation. Radiographs taken during the fragmentation stage of the disease were classified by the lateral pillar classification of Herring; 19 of our patients attained skeletal maturity and were evaluated. Clinical assessment included the Harris hip score, hip ROM, and limb length discrepancy. Radiographic assessment included sharp transverse acetabular inclination, the uncoverage percentage, the epiphyseal index before surgery (modified Eyre-Brook), at frame removal, and at the last follow-up, the epiphyseal quotient (of Sjovall), and the Stulberg classification. The mean follow-up was 7.2 years (range 4.1-11.3). The mean Harris hip score was 87.1/100 (range 49.2-94.8). An improvement in hip (ROM) of 83.3% of the normal range was restored. There was a marked improvement in the degree of pain and limp postoperatively. The hip ROM was slightly limited in most patients, and seven patients had limb shortening of between 1 and 3 cm. The mean sharp transverse acetabular inclination of the affected side was 44° (range 35-51) compared with 37° for the unaffected side (P=0.042). The mean uncoverage percentage was 36% (range 24-45) compared with 21% for the unaffected side (P=0.027). The mean epiphyseal index was 0.74 (range 0.36-0.94) before surgery, 0.78 (range 0.49-0.89) at frame removal (P=0.017), and 0.80 (range 0.54-0.91) at the last follow-up (P=0.701). The epiphyseal quotient was 0.74 (range 0.51-0.94) and the Stulberg classifications were type II in eight patients, type III in seven patients, type IV in three patients, and type V in one patient. Arthrodiastasis of the hip joint with soft tissue release may represent a good contribution toward the treatment of Legg-Calvé-Perthes disease. This method of treatment has many advantages such as easy technique, minimal rate of complications, a short hospitalization period, correction of shortening because it adds to the length of the limb, and a higher rate of acceptable results than would be expected compared with other methods. It also improves the ROM, reduces superior and lateral subluxation, and provides better radiographic sphericity of the femoral head. In addition, it does not distort the anatomy of the pelvis or the proximal femur; it can be used with equal success in older children who are typically expected to have a poor prognosis. Distraction treatment is not limited by hip stiffness, degree of femoral head deformity, or subluxation, and can be used when other methods of treatment are contraindicated. PMID:22713742

    2009-01-01

    The Joint Health and Disease Management Program in the Toronto Central Local Health Integration Network (TC LHIN) is envisioned as a comprehensive model of care for patients with hip and knee arthritis. It includes access to assessment services, education, self-management programs and other treatment programs, including specialist care as needed. As the first phase of this program, the hospitals in TC LHIN implemented a Hip and Knee Replacement Program to focus on improving access and quality of care, coordinating services and measuring wait times for patients waiting for hip or knee replacement surgery. The program involves healthcare providers, consumers and constituent hospitals within TC LHIN. The approach used for this program involved a definition of governance structure, broad stakeholder engagement to design program elements and plans for implementation and communication to ensure sustainability. The program and approach were designed to provide a model that is transferrable in its elements or its entirety to other patient populations and programs. Success has been achieved in creating a single wait list, developing technology to support referral management and wait time reporting, contributing to significant reductions in waits for timely assessment and treatment, building human resource capacity and improving patient and referring physician satisfaction with coordination of care.

  1. Degenerative Pathways of Lumbar Motion Segments

    Jensen, Rikke K.; Kjaer, Per; Jensen, Tue S.; Albert, Hanne; Kent, Peter

    2016-01-01

    BACKGROUND: Magnetic resonance imaging (MRI) is used to identify spinal pathoanatomy in people with persistent low back pain. However, the clinical relevance of spinal degenerative MRI findings remains uncertain. Although multiple MRI findings are almost always present at the same time, research...... into the association with clinical outcomes (such as pain) has predominantly focused on individual MRI findings. This study aimed to: (i) investigate how multiple MRI lumbar spine findings cluster together within two different samples of patients with low back pain, (ii) classify these clusters into...... hypothetical pathways of degeneration based on scientific knowledge of disco-vertebral degeneration, and (iii) compare these clusters and degenerative pathways between samples. METHODS: We performed a secondary cross-sectional analysis on two dissimilar MRI samples collected in a hospital department: (1) data...

    2013-01-01

    Canine degenerative myelopathy (DM) is a progressive disease process that is diagnosed late in life and mainly affects the pelvic limbs. Factors that make an ante-mortem definitive diagnosis of DM include: an insidious onset and clinical manifestation that mimics other disease processes of the pelvic limbs (hip dysplasia, cranial cruciate ligament rupture, etc.) or there may even be concurrent disease processes, old-age onset and lack of reliable diagnostic methods. Until recently, South Afr...

  3. Systems Pharmacology Links GPCRs with Retinal Degenerative Disorders.

    Chen, Yu; Palczewski, Krzysztof

    2016-01-01

    In most biological systems, second messengers and their key regulatory and effector proteins form links between multiple cellular signaling pathways. Such signaling nodes can integrate the deleterious effects of genetic aberrations, environmental stressors, or both in complex diseases, leading to cell death by various mechanisms. Here we present a systems (network) pharmacology approach that, together with transcriptomics analyses, was used to identify different G protein-coupled receptors that experimentally protected against cellular stress and death caused by linked signaling mechanisms. We describe the application of this concept to degenerative and diabetic retinopathies in appropriate mouse models as an example. Systems pharmacology also provides an attractive framework for devising strategies to combat complex diseases by using (repurposing) US Food and Drug Administration-approved pharmacological agents.

  5. Radiation treatment of painful degenerative skeletal conditions

    The study reported was intended to present own experience with irradiation for treatment of painful degenerative skeletal conditions and examine the long-term effects of this treatment. A retrospective study was performed covering the period from 1985 until 1991, examining 157 patients suffering from painful degenerative skeletal conditions who entered information on the success of their radiation treatment in a questionnaire. 94 of the questionnaires could be used for evaluation. Pain anamnesis revealed periods of more than one year in 45% of the cases. 74% of the patients had been treated without success with drug or orthopedic therapy. Immediately after termination of the radiotherapy, 38% of the patients said to be free of pain or to feel essentially relieved, while at the time the questionnaire was distributed, the percentage was 76%. Thus in our patient material, radiotherapy for treatment of painful degenerative skeletal lesions was successful in 76% of the cases and for long post-treatment periods, including those cases whith long pain anamnesis and unsuccessful conventional pre-treatment.

  6. Facet joint syndrome

    It is the purpose of the study to demonstrate the clinical relevance of degenerative changes in the facet joint of patients with low back pain irradiating to the lower extremities, and discuss some problems relating to diagnosis and different diagnosis. 119 patients presenting the listed bellow syndromes are covered by the study: scoliosis, polytopic pain vertebral syndrome, paresis and history of trauma. all patients undergo comprehensive neurological examination with special attention focused on the spine: CT and plain x-rays are taken of the lumbosacral segment to assess the condition of the facet joints. The neurological examination demonstrates in all cases pain syndrome in the lumbar spine referred to one or both lower extremities. In 56% it is a matter of persisting pain, and in 44% - recurrent. More than half of the patients complain of sacroiliac (SI) dislocation and palpatory pain. Unilateral or bilateral degenerative changes are documented by imaging studies in all patients, including: subchondral thickening, osteopathy narrowing the lateral or central part of the spinal canal with ensuing nerve root compression. The lumbosacral zygoapophyseal joints are source of pseudoradicular pain. A correlation between clinical picture and GT changes is noted in all patients with facet joint syndrome. CT is an indispensable method in diagnosing facet joint syndrome. (authors)

    1991-02-01

    In a prospective study 43 patients with shoulder pain were examined by sonography and MRI. The findings were controlled by plain radiography, arthrography, and CT arthrography. Joint effusions and humeral head defects were equally identified by MR and sonography. In the diagnosis of labrum lesions, rotator cuff lesions, subacromial spurs, and synovial inflammatory disease sonography was not as accurate as MR. A special MR scoring system improved the diagnosis of an impingement syndrome. (orig.).

    Abstract We report a case of a Calcium pyrophosphate dihydrate deposition disease (CPPD) presenting as a mass in the parotid and temporomandibular joint (TMJ) that simulated a parotid tumor. A 35 year-old man presented with pain in the left ear area. A CT Scan of the area showed a large, calcified mass surrounding the left condylar head, and extending into the infratemporal fossa. FNA of the mass showed birefringent crystals, most of which were rhomboid with occasional ones being needle shape...

    The clinical and biochemical correlations with joint damage progression over two years in a consecutive group of 68 patients with rheumatoid arthritis with disease duration of less than two years are reported. Joint damage was assessed with Larsen's severity scale and a measure of change in progression rate constructed. Initial haemoglobin concentration, Ritchie index, and Waaler-Rose titre in combination accounted for one third of the variance in joint damage progression. Rheumatoid factor (...

    The purpose of this article is to summarize the updated DEGRO consensus S2e guideline recommendations for the treatment of benign painful degenerative skeletal disorders with low-dose radiotherapy. This overview reports on the role of low-dose radiotherapy in the treatment of enthesiopathies (shoulder syndrome, trochanteric bursitis, plantar fasciitis, and elbow syndrome) and painful arthrosis (knee, hip, hand, and finger joints). The most relevant aspects of the DEGRO S2e Consensus Guideline Radiation Therapy of Benign Diseases 2014 regarding diagnostics, treatment decision, dose prescription as well as performance of radiotherapy and results are summarized. For all indications mentioned above, retrospective and some prospective analyses have shown remarkable effects in terms of pain relief. Nevertheless, the Level of Evidence (LoE) and the Grade of Recommendation (GR) vary: LoE 1b-4 and GR A-C. Low-dose radiotherapy for painful degenerative skeletal disorders is effective in the majority of the patients and therefore it may be a reasonable therapeutic alternative when simple and non-invasive methods have been used without persistent success. For all discussed entities, single fraction doses of 0.5-1.0 Gy and total doses of 3.0-6.0 Gy/series applied with 2-3 fractions per week are recommended. (orig.) [German] Zusammenfassung der Empfehlungen der DEGRO-S2e-Leitlinie zur Niedrigdosis-Radiotherapie von gutartigen schmerzhaften degenerativen Skeletterkrankungen. Die vorliegende Zusammenfassung berichtet ueber die Bedeutung der Niedrigdosis-Radiotherapie in der Behandlung von Enthesiopathien (Schultersyndrom, Ellenbogensyndrom, Bursitis trochanterica, Fasciitis plantaris) und schmerzhaften Arthrosen (Knie-, Hueft, Hand- und Fingergelenksarthrosen). Die wichtigsten Aspekte der aktuellen DEGRO-S2e-Konsensus-Leitlinie Strahlentherapie gutartiger Erkrankungen bezueglich Diagnostik, Therapieentscheidungen, Dosisempfehlungen und Durchfuehrung einer Radiotherapie werden zusammengefasst. Fuer alle genannten Entitaeten wurde in zahlreichen retrospektiven und einigen prospektiven Untersuchungen ein bemerkenswerter Effekt der Niedrigdosis-Radiotherapie im Sinne einer Schmerzlinderung beschrieben. Je nach Entitaet wurden Evidenzlevel (LoE) von 1b-4 festgestellt, sodass unterschiedliche Empfehlungsgrade (GR) von A-C fuer den Einsatz der Radiotherapie ausgesprochen wurden. Die Niedrigdosis-Radiotherapie von benignen schmerzhaften degenerativen Skeletterkrankungen ist bei der Mehrheit der Patienten effektiv im Sinne einer Schmerzlinderung und ist daher insbesondere fuer Patienten, bei denen andere konservative Verfahren ohne Einsatz ionisierender Strahlung zu keiner anhaltenden Verbesserung der Schmerzsymptomatik gefuehrt haben, eine gut begruendbare therapeutische Alternative. Empfohlen wird die Durchfuehrung der Bestrahlung mit Fraktionsdosen von 0,5-1,0 Gy bis zu Gesamtdosen von 3,0-6,0 Gy/Bestrahlungsserie sowie 2-3 Fraktionen pro Woche. (orig.)

  11. (18)F Sodium Fluoride PET/CT in Patients with Prostate Cancer: Quantification of Normal Tissues, Benign Degenerative Lesions, and Malignant Lesions.

    Understanding the range and variability of normal, benign degenerative, and malignant (18)F sodium fluoride ((18)F NaF) positron emission tomography/computed tomography (PET/CT) uptake is important in influencing clinical interpretation. Further, it is essential for the development of realistic semiautomated quantification techniques and simulation models. The purpose of this study is to determine the range of these values in a clinically relevant patient population with prostate cancer. (18)F NaF PET/CT scans were analyzed in patients with prostate cancer (n = 47) referred for evaluation of bone metastases. Mean and maximum standardized uptake values [SUVs (SUVmean and SUVmax)] were made in normal background regions (n = 470) including soft tissues (liver, aorta, bladder, adipose, brain, and paraspinal muscle) and osseous structures (T12 vertebral body, femoral diaphyseal cortex, femoral head medullary space, and ribs). Degenerative joint disease (DJD; n = 281) and bone metastases (n = 159) were identified and quantified by an experienced reader using all scan information including coregistered CT. For normal bone regions, the highest (18)F NaF PET SUVmean occurred in T12 (6.8 ± 1.4) and it also showed the lowest coefficient of variation (cv = 21%). For normal soft tissues, paraspinal muscles showed very low SUVmean (0.70 ± 0.11) and also showed the lowest variability (cv = 16%). Average SUVmean in metastatic lesions is higher than uptake in benign degenerative lesions but values showed a wide variance and overlapping values (16.3 ± 13 vs 11.1 ± 3.8; P < 0.00001). The normal (18)F NaF PET uptake values for prostate cancer patients in normal background, benign degenerative disease, and osseous metastases are comparable to those reported for a general population with a wide variety of diagnoses. These normal ranges, specifically for prostate cancer patients, will aid in clinical interpretation and also help to establish the basis of normal limits in a semiautomated data analysis algorithm.

  12. Lumbar degenerative spinal deformity: Surgical options of PLIF, TLIF and MI-TLIF

    Hey Hwee Weng

    2010-01-01

    Full Text Available Degenerative disease of the lumbar spine is common in ageing populations. It causes disturbing back pain, radicular symptoms and lowers the quality of life. We will focus our discussion on the surgical options of posterior lumbar interbody fusion (PLIF and transforaminal lumbar interbody fusion (TLIF and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF for lumbar degenerative spinal deformities, which include symptomatic spondylolisthesis and degenerative scoliosis. Through a description of each procedure, we hope to illustrate the potential benefits of TLIF over PLIF. In a retrospective study of 53 ALIF/PLIF patients and 111 TLIF patients we found reduced risk of vessel and nerve injury in TLIF patients due to less exposure of these structures, shortened operative time and reduced intra-operative bleeding. These advantages could be translated to shortened hospital stay, faster recovery period and earlier return to work. The disadvantages of TLIF such as incomplete intervertebral disc and vertebral end-plate removal and potential occult injury to exiting nerve root when under experienced hands are rare. Hence TLIF remains the mainstay of treatment in degenerative deformities of the lumbar spine. However, TLIF being a unilateral transforaminal approach, is unable to decompress the opposite nerve root. This may require contralateral laminotomy, which is a fairly simple procedure.The use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF to treat degenerative lumbar spinal deformity is still in its early stages. Although the initial results appear promising, it remains a difficult operative procedure to master with a steep learning curve. In a recent study comparing 29 MI-TLIF patients and 29 open TLIF, MI-TLIF was associated with longer operative time, less blood loss, shorter hospital stay, with no difference in SF-36 scores at six months and two years. Whether it can replace traditional TLIF as the surgery of choice for degenerative lumbar deformity remains unknown and more studies are required to validate the safety and efficiency.

  13. Current knowledge and importance of dGEMRIC techniques in diagnosis of hip joint diseases

    Accurate assessment of early hip joint cartilage alterations may help optimize patient selection and follow-up of hip joint preservation surgery. Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is sensitive to the glycosaminoglycan content in cartilage that is lost early in the development of osteoarthritis (OA). Hence, the dGEMRIC technique holds promise for the development of new diagnostic and therapeutic procedures. However, because of the location of the hip joint deep within the body and due to the fairly thin cartilage layers that require high spatial resolution, the diagnosis of early hip joint cartilage alterations may be problematic. The purpose of this review is to outline the current status of dGEMRIC in the assessment of hip joint cartilage. A literature search was performed with PubMed, using the terms ''cartilage, osteoarthritis, hip joint, MRI, and dGEMRIC'', considering all levels of studies. This review revealed that dGEMRIC can be reliably used in the evaluation of early stage cartilage pathology in various hip joint disorders. Modifications in the technique, such as the operation of three-dimensional imaging and dGEMRIC after intra-articular contrast medium administration, have expanded the range of application. Notably, the studies differ considerably in patient selection and technical prerequisites. Furthermore, there is a need for multicenter prospective studies with the required technical conditions in place to establish outcome based dGEMRIC data to obtain, in conjunction with clinical data, reliable threshold values for normal and abnormal cartilage, and for hips that may benefit from conservative or surgical treatment.

    Background and Purpose: The etiologic diagnosis of parkinsonian syndromes is of particular importance when considering syndromes of vascular or degenerative origin. The purpose of this study is to find differences in the white-matter architecture between those two groups in elderly patients. Materials and Methods: Thirty-five patients were prospectively included (multiple-system atrophy, n = 5; Parkinson's disease, n = 15; progressive supranuclear palsy, n = 9; vascular parkinsonism, n = 6), with a mean age of 76 years. Patients with multiple-system atrophy, progressive supranuclear palsy and Parkinson's disease were grouped as having parkinsonian syndromes of degenerative origin. Brain MRIs included diffusion tensor imaging. Fractional anisotropy and mean-diffusivity maps were spatially normalized, and group analyses between parkinsonian syndromes of degenerative origin and vascular parkinsonism were performed using a voxel-based approach. Results: Statistical parametric-mapping analysis of diffusion tensor imaging data showed decreased fractional anisotropy value in internal capsules bilaterally in patients with vascular parkinsonism compared to parkinsonian syndromes of degenerative origin (p = 0.001) and showed a lower mean diffusivity in the white matter of the left superior parietal lobule (p = 0.01). Fractional anisotropy values were found decreased in the middle cerebellar peduncles in multiple-system atrophy compared to Parkinson's disease and progressive supranuclear palsy. The mean diffusivity was increased in those regions for these subgroups. Conclusion: Clinically defined vascular parkinsonism was associated with decreased fractional anisotropy in the deep white matter (internal capsules) compared to parkinsonian syndromes of degenerative origin. These findings are consistent with previously published neuropathological data.

  16. Current developments in imaging of the temporomandibular joint

    The purpose of this paper is to provide a simple systematic approach to the diagnosis of polyarticular and monoarticular disease. The first part deals with common polyarticular disease, specifically the inflammatory, crystalline, and degenerative arthritides. The changes seen around the joint, as well as the distribution of the changes, characteristics of each anthropathy are demonstrated through the use of hand films. The second part of the presentation addresses the less well-known monoarticular diseases, specifically disorders that are diagnosed primarily by the radiologist rather than the clinician. These disorders include infectious arthritis, pigmented villonodular synovitis, synovial chondromatosis, and neuropathic arthropathy. The radiographic findings are not well known. Three categories of radiographic abnormalities are emphasized as an aid to diagnosis: juxtaarticular osteoporosis, subchondral cysts, and synovial calcification and debris

  19. Diagnostic steps in disc luxations and other frequent diseases of the temporomandibular joint

    Modern diagnosis of the temporomandibular joint (TMJ) consists of multiple steps, based on each other and amplifying one another. The first step is the clinical functional analysis, respecting general medical as well as specific dental aspects. If need arises electronic axiography, recording the movement of TMJ hingeaxis, is being added as well as occlusal analysis on mounted plaster casts. In case of open questions at this point of analysis, magnetresonance- and computer-tomographic imaging is brought in. The present paper is an overview describing the current step by step diagnosis of TMJ disorders, with special attention to luxation-reduction mechanism in the joints. (orig.)

    2013-01-01

    The distal radioulnar joint (DRUJ) is critical to the function of the forearm as a mechanical unit. This paper is concerned with the concepts and observations that have changed understanding of the function of the DRUJ, notably with respect to the biomechanics of this joint. The DRUJ has been shown to be important in acting to distribute load and removal of the ulna head leads to the biomechanical equivalent of a one-bone forearm. The soft tissues with topographical relations to the distal fo...

    Cartilage repair by bone marrow derived mesenchymal stem cells (MSCs) can be influenced by inflammation in the knee. Next to synovium, the infrapatellar fat pad (IPFP) has been described as a source for inflammatory factors. Here, we investigated whether factors secreted by the IPFP affect chondrogenesis of MSCs and whether this is influenced by different joint pathologies or obesity. Furthermore, we examined the role of IPFP resident macrophages. First, we made conditioned medium from IPFP obtained from osteoarthritic joints, IPFP from traumatically injured joints during anterior cruciate ligament reconstruction, and subcutaneous adipose tissue. Additionally, we made conditioned medium of macrophages isolated from osteoarthritic IPFP and of polarised monocytes from peripheral blood. We evaluated the effect of different types of conditioned medium on MSC chondrogenesis. Conditioned medium from IPFP decreased collagen 2 and aggrecan gene expression as well as thionin and collagen type 2 staining. This anti-chondrogenic effect was the same for conditioned medium from IPFP of osteoarthritic and traumatically injured joints. Furthermore, IPFP from obese (Body Mass Index >30) donors did not inhibit chondrogenesis more than that of lean (Body Mass Index cartilage genes, as did peripheral blood monocytes stimulated with pro-inflammatory cytokines. The IPFP and the resident pro-inflammatory macrophages could therefore be targets for therapies to improve MSC-based cartilage repair. PMID:26629970

    Full Text Available Objective: Various factors are known to determine the disease activity in patients with rheumatoid arthritis (RA. The ‘simplified disease activity’ index (SDAI is new tool of measurement of disease activity. The present study was designed to assess validity of SDAI using C-reactive protein (CRP titer in comparison to ‘disease activity score in 28 joints’ (DAS28 in Iraqi patients with active RA. Methods: Sixty nine Iraqi RA patients were included in this study. All patients were active and fulfilled the ACR (American College of Rheumatology classification criteria. Full history was taken and complete clinical examination was done for all patients. Patients' age, sex, number of swollen joints, visual analogue scale (VAS, and evaluators’ global assessment (EGA were documented. Laboratory analysis included erythrocyte sedimentation rate (ESR, CRP, SDAI and DAS28 were measured to assess disease activity. Results: The results revealed direct significant correlation between SDAI and DAS28 (r = 0.903, p < 0.001, and reported a good agreement between SDAI and DAS28 (κ = 0.777, p < 0.001. SDAI was found as a valid measure for disease activity using CRP as a screening test compared to DAS28 (AUC = 0.983, p < 0.001. Conclusion: SDAI is a valid and sensitive measure for assessment of rheumatoid arthritis disease activity that is comparable with the DAS28 using semi quantitative method to estimate CRP.

  5. Minimally-invasive posterior lumbar stabilization for degenerative low back pain and sciatica. A review

    The most diffused surgical techniques for stabilization of the painful degenerated and instable lumbar spine, represented by transpedicular screws and rods instrumentation with or without interbody cages or disk replacements, require widely open and/or difficult and poorly anatomical accesses. However, such surgical techniques and approaches, although still considered “standard of care”, are burdened by high costs, long recovery times and several potential complications. Hence the effort to open new minimally-invasive surgical approaches to eliminate painful abnormal motion. The surgical and radiological communities are exploring, since more than a decade, alternative, minimally-invasive or even percutaneous techniques to fuse and lock an instable lumbar segment. Another promising line of research is represented by the so-called dynamic stabilization (non-fusion or motion preservation back surgery), which aims to provide stabilization to the lumbar spinal units (SUs), while maintaining their mobility and function. Risk of potential complications of traditional fusion methods (infection, CSF leaks, harvest site pain, instrumentation failure) are reduced, particularly transitional disease (i.e., the biomechanical stresses imposed on the adjacent segments, resulting in delayed degenerative changes in adjacent facet joints and discs). Dynamic stabilization modifies the distribution of loads within the SU, moving them away from sensitive (painful) areas of the SU. Basic biomechanics of the SU will be discussed, to clarify the mode of action of the different posterior stabilization devices. Most devices are minimally invasive or percutaneous, thus accessible to radiologists’ interventional practice. Devices will be described, together with indications for patient selection, surgical approaches and possible complications

  7. High Spatial Resolution MRI of Cystic Adventitial Disease of the Iliofemoral Vein Communicating with the Hip Joint

    Venous cystic adventitial disease (CAD) is an extremely rare entity, and so far less than 20 cases have been described in the literature. Herein, we describe the imaging findings of CAD of iliofemoral vein in a 51-year-old woman who presented with leg swelling with special emphasis on high spatial resolution MRI, which demonstrated communication of the cyst with the hip joint. To our knowledge, this is the first description of high spatial resolution MRI findings in venous CAD supporting a new theory about the pathogenesis of venous CAD

  8. Acute degenerative changes in intervertebral disks

    Correlation of MR images with anatomic sections in humans has provided useful information on imaging chronic disk degeneration. Correlative studies in dogs can be equally useful because disk herniation is common in dogs, disk conditions that predispose to herniation have been identified in dogs, and anatomic studies can be obtained in acute canine disk degeneration. MR imaging is performed with specially designed surface coils in a 1.5-T imager. Exactly corresponding anatomic sections are obtained with a cryomicrotome. Histologic sections are prepared in most cases. Thirty dogs, including 60 with abnormal and 30 with normal disks, have been studied. Exact anatomic-MR correlations will be illustrated in spontaneous and experimental disk degeneration. MR images reflect the content of fibrous tissue and gel in the disk and sequential changes of disk degeneration. A classification of degenerative changes is made

    Serum amyloid A (SAA) is a major acute phase protein in dogs. However, knowledge of qualitative properties of canine SAA and extent of its synthesis in extrahepatic tissues is limited. The aim of the study was to investigate expression of different SAA isoforms in serum and synovial fluid in...... with systemic inflammatory activity, and up to four major isoforms with apparent isoelectric points between 6.1 and 7.9 were identified. In synovial fluid from inflamed joints one or more highly alkaline SAA isoforms (with apparent isoelectric points above 9.3) were identified, with data suggesting...

  12. The relationship between the cerebral blood flow, oxygen consumption and glucose metabolism in primary degenerative dementia

    The CBF, CMRO2 and CMRGlu were measured in patients with primary degenerative dementia including 5 patients with dementia of Alzheimer's type and 4 patients with Pick's disease, and then the correlation between the cerebral blood flow and energy metabolism was evaluated. The control subjects consisted of 5 age-matched normal volunteers. The CBF, CMRO2 and CMRGlu decreased in the bilateral frontal, temporal and parietal regions in the patients with Alzheimer's dementia, while they decreased in the bilateral frontal and temporal regions in the patients with Pick's disease. Both the CBF and CMRO2 were closely correlated with each other. However, the CMRGlu was more severely impaired than the CBF or CMRO2 in both pathological conditions. These results suggested that CMRGlu began to decrease before the reduction of the aerobic metabolism and thus measuring the CMRGlu is considered to be the most sensitive method for detecting abnormal regions in primary degenerative dementia.

    Full Text Available Abstract Background Research involving more representative samples is needed to extend our understanding of the broader impact of obesity in hip or knee joint disease (arthritis and OA beyond clinical settings. Although population-based research has been conducted in the United States, how these findings translate to other countries is unclear. Using a national approach, this study explored associations between obesity and the burden of hip and knee joint disease in Australia (in terms of prevalence, pain, stiffness, function, Health-Related Quality of Life (HRQoL and disease severity. Methods A random sample of 5000 Australians (≥39 years from the federal electoral roll was invited to complete a mailed questionnaire to identify doctor-diagnosed hip arthritis, hip OA, knee arthritis and knee OA and evaluate the burden of these conditions. Validated questionnaires included the WOMAC Index, Assessment of Quality of Life instrument and Multi-Attribute Prioritisation Tool. Body Mass Index (BMI was classified into underweight/normal weight (≤24.99 kg/m2, overweight (25–29.99 or obese (≥30. Multiple logistic regression was used to estimate odds of arthritis and OA, with demographic and socioeconomic variables included in the models. Associations between BMI and other variables were investigated using analysis of covariance, with adjustment for age and sex. Results Data were available from 1,157 participants (23%. Overweight participants had increased odds of knee arthritis (adjusted OR (AOR 1.87, 95%CI 1.14-3.07 and knee OA (AOR 2.11, 95%CI 1.07-4.15. Obesity was associated with higher prevalence of hip arthritis (AOR 2.18, 95%CI 1.17-4.06, knee arthritis (AOR 5.47, 95%CI 3.35-8.95 and knee OA (AOR 7.35, 95%CI 3.85-14.02. Of those with arthritis or OA, obese individuals reported more pain (for hip arthritis, hip OA and knee OA, greater stiffness (for hip arthritis, knee arthritis and knee OA, worse function (all diagnoses, lower HRQoL (for hip arthritis and hip OA and greater disease severity (all diagnoses. Conclusions This national study has demonstrated that the odds of arthritis and OA was up to 7 times higher for obese individuals, compared with those classified as underweight/normal weight. Concurrent obesity and joint disease had a marked impact on several key aspects of wellbeing, highlighting the need for public health interventions.

  14. Calcium pyrophosphate dihydrate deposition disease (CPPD/Pseudogout of the temporomandibular joint – FNA findings and microanalysis

    2008-04-01

    Full Text Available Abstract We report a case of a Calcium pyrophosphate dihydrate deposition disease (CPPD presenting as a mass in the parotid and temporomandibular joint (TMJ that simulated a parotid tumor. A 35 year-old man presented with pain in the left ear area. A CT Scan of the area showed a large, calcified mass surrounding the left condylar head, and extending into the infratemporal fossa. FNA of the mass showed birefringent crystals, most of which were rhomboid with occasional ones being needle shaped, embedded in an amorphous pink substance. Scanning electron microscopy (SEM with energy dispersive x-ray spectroscopy (EDS of these crystals showed peaks corresponding to calcium and phosphorus. SEM/EDS is a rapid method of diagnosing calcium pyrophosphate dihydrate deposition disease (CPPD and an alternative to more commonly used method of special staining of cell block sections coupled with polarizing microscopy.

  15. Advantages and limits of sup(99m)Tc pyrophosphate scintigraphy in the study of joint diseases

    The results of sup(99m)Tc pyrophosphate bone scintigraphy are studied for a wide range of joint diseases. 215 scintigraphs are analysed, the results compared with those of authors who have used not only Tc phosphates but also other isotopes after comparison of their advantages and disadvantages, and possible applications suggested for each type of lesion. - The 99m Tc pyrophosphate scintigraphic examination is simple, harmless (a whole-skeleton examination delivers only 80 millirads to the narrow whereas a set of spine and pelvis X-rays delivers 325), reliable and highly sensitive, often anticipating data from radiographic examinations. - In the majority of developing joint diseases of whatever kind, apart from arthroses and certain osteolytic lesions unaccompanied by any healing reaction, a hyperfixation is observed. Generally speaking a scintigraph may be requested whenerver an evolutive bone lesion is suspected in the absence of clinical, radiological and biological evidence. The major disadvantage of the method is that, being highly sensitive, it lacks specificity and is hence unable alone to provide an etiological diagnosis

    Ten years ago, the diagnosis discussion of a dementia case for the old patient was limited to two pathologies: the Alzheimer illness and the Pick illness. During these last years, the frame of these primary degenerative dementia has fallen into pieces. The different diseases and the results got with single photon emission computed tomography are discussed. for example: fronto-temporal dementia, primary progressive aphasia, progressive apraxia, visio-spatial dysfunction, dementia at Lewy's bodies, or cortico-basal degeneration.

Discopatia degenerativa, resultados basados en la evidencia científica Present state of degenerative back surgery and its implications in the management of chronic lumbar pain, canal stenosis and degenerative disk disease: Evidence based outcomes

    F. J. Robaina

    2006-04-01

    Full Text Available La búsqueda de soluciones terapéuticas para pacientes con síndromes de dolor postlaminectomía o dolor lumbar crónico constituye uno de los aspectos fundamentales de la carga de trabajo de las Unidades de Dolor Crónico. A la luz de los resultados de las publicaciones científicas y revisiones que han seguido los principios de la "medicina basada en la evidencia", cuando se analizan los resultados de la cirugía de la hernia dis-cal, se observa, cómo no existe todavía en la literatura mundial ningún trabajo científico correctamente realizado que compare la cirugía y el tratamiento conservador sin ningún tipo de sesgo científico en la recogida de datos. Por esa razón, se siguen buscando soluciones no quirúrgicas a este problema. Un aspecto fundamental a tener en cuenta a la hora de analizar los resultados de la cirugía de la columna, es lo que se denomina en los medios económicos de la bolsa Americana la "burbuja de la cirugía de columna". La literatura científica no muestra evidencias claras en los estudios coste-beneficio de muchas técnicas de cirugía instrumentada de la columna sobre el tratamiento conservador. No ha sido demostrado que la cirugía de fusión vertebral y el reemplazo del disco intervertebral sea mejor que el tratamiento conservador. Destacar, que actualmente, "existen relaciones entre la industria y el dolor lumbar" y que también "existe una industria del dolor lumbar". No obstante, "el mercado de la cirugía de la columna", sigue aumentando, ya que los pacientes siguen demandando soluciones para resolver su dolor de espalda. La marea de la evidencia científica parece que va en contra de la fusión espinal en la enfermedad discal degenerativa, el dolor discogénico y el dolor lumbar inespecífico. Después de dos décadas de avances tecnológicos en este campo, el resultado de las fusiones espinales es mediocre. Estudios epidemiológicos recientes muestran que la "fusión espinal" debe aceptarse como "un método no probado o experimental para el tratamiento del dolor lumbar crónico". La literatura quirúrgica sobre la fusión espinal en los últimos 20 años según revisiónes Cochrane establece que: 1- ésta es incompleta, no fiable y descuidada; 2- la instrumentación parece que aumenta ligeramente la tasa de fusión; 3- la instrumentación no mejora los resultados clínicos en general, careciéndose de estudios particulares de subgrupos de pacientes. Se precisan estudios aleatorios que comparen los resultados quirúrgicos con la historia natural, el placebo o el tratamiento conservador. Las Guías Europeas para el manejo del dolor crónico lumbar, muestran como existe una "fuerte evidencia" que indica que la cirugía compleja y demandante de la columna vertebral lumbar en la que se emplean diferentes formas de instrumentación espinal, no es más efectiva que una simple, más segura y mas barata fusión posterolateral sin instrumentación. Otros estudios recientes ponen de manifiesto cómo se está produciendo una tendencia hacia la utilización de "técnicas mínimamente invasivas", abandonando las fusiones transpediculares, lo que nos indica claramente que debemos aplicar correctamente el conocimiento basado en la evidencia científica acumulado a lo largo de por lo menos 20 años. Todo ello, nos permite, recomendar el "abandono de la senda instrumentista" en gran cantidad de indicaciones actuales, y buscar otros caminos en el campo del tratamiento conservador y rehabilitador correctamente aplicados, utilizando antes de la cirugía descompresiva y de fusión vertebral todos los recursos intervencionistas que actualmente ofrece el tratamiento moderno del dolor crónico.The finding of therapeutical solutions for patines suffering of chronic low back pain and failed back syndrome is one of the main work load that Chronic Pain Units have to manage every day. The results displayed in publications done following the "principles of evidence based medicine", shows that still there is not any correctly done study that compares the conservative and surgical treatments in the manegement of her-niated lumbar disc. For that reason , we are still triying to find new treatment options in the nonsurgical field of her-niated lumbar disc. When we analize the published results of the spine surgery, we must beard in mind what have been call in the "American Stock and Excahnge" "the bubble of spine surgery". The scientific literature does not show clear evidence in the cost-benefict studies of most instrumented surgical interventions of the spine compare with the conservative treatments. It has not been yet demostrated that fusion surgery and disc replacement are better options than the conservtive treatment. It´s necesary to point out that at present "there are relationships between the industry and back pain and there is also an industry of the back pain" . Nontheless, the "market of the spine surgery" is growing up because patients are demanding solutions for their back problems. The tide of scientific evidence seams to go against of the spinal fusions in the degenerative disc disease, discogenic pain and inespecific back pain. After decades of technological advances in this field, the results of spinal fusions are mediocre. Recent epidemiological studies show that "spinal fusion must be accepted as a non proved or experimental method for the treatment of back pain". The surgical literature on spinal fusion published in the last 20 years following the Cochrane’s method stablish that: 1- this is at least incomplete, not realiable and careless; 2- the instrumentation seems to sligthy increase the fusion rate ; 3- the instrumentation doesn’t improve the clinical results in general, lacking studies in subgroups of patients. We still are needing randomized studies to compare the surgical results with the natural history of the disease, the pacebo effect, or the conservative treatment. The European Guidelines for lumbar chronic pain management shows a strong evidence indicating that complex and demanding spine surgery where different instrumentation is used, is not more effective than a simple, safer and cheaper posterolateral fusion without instrumentation. Recently, the literature published in this field, is showing us a tendency to use again "minimally invasive techniques", abandon transpedicular fusions, and indicating clearly that we must apply the knowledge based on the scientific evidence accumulated at least along the last 20 years. In conclussion, based in the modern information, we must recomend the abandon of the instrumented pathway in a great number of present indications for spine surgery, and look for new management strategies in the field of rehabilitation and conservative treatments correctly apply, using before the decompresive and instrumented surgery all the intervention-al techniques that are presently offer in the field of modern chronic pain treatment.

  2. Environmental Radon Gas and Degenerative Conditions An Overview

    Radon, a naturally occurring radioactive gas, has variable distribution in the environment as a decay product of uranium occurring in a wide range of rocks, soils and building materials. Although radon dissipates rapidly in outdoor air, it concentrates in the built environment, and inhalation of 222Rn and its progeny 218Po and 214Po is believed to provide the majority of the radioactive dose to the respiratory system. While the connection between radon and lung cancer has long been recognised and investigated, recent studies have highlighted potential links between radon and other conditions, among them Multiple Sclerosis, Alzheimer and Parkinson Diseases, and Paget Disease of Bone. A strong case exists for clarifying the relationship between radon and these other conditions, not least since radon remediation to reduce lung cancer may conceivably have additional benefits hitherto unrecognized. The present status of the postulated links between environmental radon gas and degenerative conditions is reviewed, and recommendations for further research into levering current anti-radon campaigns are made.

  4. Acquired degenerative changes of the intervertebral segments at and suprajacent to the lumbosacral junction A radioanatomic analysis of the nondiscal structures of the spinal column and perispinal soft tissues

    Jinkins, J. Randy E-mail: jrjinkins@aol.com

    2004-05-01

    A review of the imaging features of normal and degenerative anatomy of the spine on medical imaging studies shows features that have been largely overlooked or poorly understood by the imaging community in recent years. The imaging methods reviewed included computed tomography (CT) with multiplanar reconstructions and magnetic resonance imaging (MRI). A routine part of the MRI examination included fat-suppressed T2 weighted fast-spin- or turbo-spin-echo acquisitions. As compared to the normal features in asymptomatic volunteers, alterations in the observed CT/MRI morphology and MR signal characteristics were sought in symptomatic individuals. Findings in symptomatic subjects which departed from the normal anatomic features of the posterior spinal elements in asymptomatic volunteers included: rupture of the interspinous ligament(s), neoarthrosis of the interspinous space with perispinous cyst formation, posterior spinal facet (zygapophyseal joint) arthrosis, related central spinal canal, lateral recess (subarticular zone) and neural foramen stenosis, posterior element alterations associated with various forms of spondylolisthesis, and perispinal muscle rupture/degeneration. These findings indicate that the posterior elements are major locations of degenerative spinal and perispinal disease that may accompany or even precede degenerative disc disease. Although not as yet proven as a reliable source of patient signs and symptoms in all individuals, because these observations may be seen in patients with radicular, referred and/or local low back pain, they should be considered in the evaluation of the symptomatic patient presenting with a clinical lumbosacral syndrome. Imaging recommendations, in addition to the usual close scrutiny of these posterior spinal elements and perispinal soft tissues on CT and MRI, include the acquisition of high-resolution multiplanar CT reconstructions, and fat-suppressed T2 weighted fast-spin- or turbo-spin-echo sequence MRI in at least one plane in every examination of the lumbar spine.

  5. Studies of computed tomography as a contribution to differential diagnosis between dementia due to cerebrovascular disease (multi-infract type) and due to primarily degenerative cerebral atrophy (Alzheimers type)

    Studies of computed tomography were performed in 367 patients diagnosed as dementia clinically. The mean age was 70.1 years. By the clinicians 240 were classified as senile dementia of Alzheimer's type, 79 as multiinfarct dementia, and 48 were not determined definitely. In 3%, the CT studies did detect treatable causes like tumors, subdural hematomas and communicating hydrocephalus. In about 57% was found by CT a diffuse brain atrophy without focal tissue changes as to expect if occurring a cerebrovascular disease. In 25% there were focal changes of the brain tissue in CT to define as residuals of infarctions in addition to the signs of cerebral atrophy. The results of the CT studies were normal in 15% despite of the evidence of dementia clinically. The analysis of the material did show that a cerebrovascular disease as a cause of dementia is suspected clinically in much more cases than CT studies are able to prove focal pathological changes of the brain tissue due to disorders of cerebral blood flow really.

  7. Treatment choice for osteoarthritis of the knee joint according to semi-automatic MRI based assessment of disease severity

    Objective assessment of disease severity of osteoarthritis of the knee joint (OA knee) is fundamental to establish adequate treatment system. Regrettably, there is no such a reliable system. Grading system based upon X-ray findings or measurement of joint space narrowing is widely used method for this purpose but they are still far from satisfaction. Our previous study elucidated that measuring irregularity of the contour of the femoral condyle on MRI (irregularity index) using newly developed software enabled us to assess disease severity of OA objectively. Advantages of this system are expressing severity by metric variable and semi-automatic character. In the present study, we examined relationship between treatment selection and irregularity index. Sixty-one medial type OA knees that received total knee arthroplasty (TKA), arthroscopic surgery (AS), and conservative treatment (CT) were involved. Their x-ray grading, irregularity index were recorded at the time of corresponding treatment. Irregularity index of each group were compared. As for AS group, pre- and post-operative knee score employing JOA score were also examined to study relationship between irregularity index and improvement of knee score. All the four parameters that represent irregularity of femoral condyle were significantly higher in TKA group than in AS group, whereas no significant difference was observed between AS group and CT group. Negative correlation was observed between irregularity index and improvement of knee score after arthroscopic surgery. Although treatment selection was determined by skillful knee surgeon in this series, irregularity index could indicate adequate timing of TKA. It also served as an indicator to predict outcome of arthroscopic surgery, and could be used as to show limitation of arthroscopic surgery. Our new system to assess disease severity of OA knee can serve as an index to determine treatment options. (author)

    Cheilitis granulomatosa is characterized by granulomatous lip swelling. We report a case of a 13-year-old girl who presented with orofacial swelling and arthralgia, who eventually was diagnosed with Crohn's disease, which was successfully treated with infliximab and azathioprine combination therapy. Recurrent or persistent orofacial swelling should prompt consideration of cheilitis granulomatosa, and further diagnostic evaluation to exclude the presence of Crohn's disease seems warranted.

Recognizing that most communities include multiple hosts and pathogens, we tested how variation in host and parasite diversity influenced disease risk. By combining field surveys and experiments involving amphibian hosts and trematode parasites, we show that realistic changes in host and parasite richness inhibit transmission of the deadliest parasite, Ribeiroia ondatrae.

  13. Automatic 3D MR image registration and its evaluation for precise monitoring of knee joint disease

    We describe a technique for the registration of three dimensional (3D) knee femur surface points from MR image data sets; it is a technique that can track local cartilage thickness changes over time. In the first coarse registration step, we use the direction vectors of the volume given by the cloud of points of the MR image to correct for different knee joint positions and orientations in the MR scanner. In the second fine registration step, we propose a global search algorithm that simultaneously determines the optimal transformation parameters and point correspondences through searching a six dimensional space of Euclidean motion vectors (translation and rotation). The present algorithm is grounded on a mathematical theory- Lipschitz optimization. Compared with the other three registration approaches (iterative closest point (ICP), EM-ICP, and genetic algorithms), the proposed method achieved the highest registration accuracy on both animal and clinical data.

  14. Current Trends in the Use of Patient-Reported Outcome Instruments in Degenerative Cervical Spine Surgery.

    Ueda, Haruki; Cutler, Holt S; Guzman, Javier Z; Cho, Samuel K

    2016-05-01

    Study Design Bibliometric analysis. Objective To determine trends, frequency, and distribution of patient-reported outcome instruments (PROIs) in degenerative cervical spine surgery literature over the past decade. Methods A search was conducted via PubMed from 2004 to 2013 on five journals (The Journal of Bone and Joint Surgery, The Bone and Joint Journal, The Spine Journal, European Spine Journal, and Spine), which were chosen based on their impact factors and authors' consensus. All abstracts were screened and articles addressing degenerative cervical spine surgery using PROIs were included. Articles were then analyzed for publication date, study design, journal, level of evidence, and PROI trends. Prevalence of PROIs and level of evidence of included articles were analyzed. Results From 19,736 articles published, 241 articles fulfilled our study criteria. Overall, 53 distinct PROIs appeared. The top seven most frequently used PROIs were: Japanese Orthopaedic Association score (104 studies), visual analog scale for pain (100), Neck Disability Index (72), Short Form-36 (38), Nurick score (25), Odom criteria (21), and Oswestry Disability Index (15). Only 11 PROIs were used in 5 or more articles. Thirty-three of the PROIs were appeared in only 1 article. Among the included articles, 16% were of level 1 evidence and 32% were of level 4 evidence. Conclusion Numerous PROIs are currently used in degenerative cervical spine surgery. A consensus on which instruments to use for a given diagnosis or procedure is lacking and may be necessary for better communication and comparison, as well as for the accumulation and analysis of vast clinical data across multiple studies.

  15. Novel Lesions of Bones and Joints Associated with Chikungunya Virus Infection in Two Mouse Models of Disease: New Insights into Disease Pathogenesis

    Goupil, Brad A.; McNulty, Margaret A.; Martin, Matthew J.; McCracken, Michael K.; Christofferson, Rebecca C.; Mores, Christopher N.

    2016-01-01

    Chikungunya virus is an arbovirus spread predominantly by Aedes aegypti and Ae. albopictus mosquitoes, and causes debilitating arthralgia and arthritis. While these are common manifestations during acute infection and it has been suggested they can recur in patients chronically, gaps in knowledge regarding the pathogenesis still exist. Two established mouse models were utilized (adult IRF 3/7 -/- -/- and wild-type C57BL/6J mice) to evaluate disease manifestations in bones and joints at various timepoints. Novel lesions in C57BL/6J mice consisted of periostitis (91%) and foci of cartilage of necrosis (50% of mice at 21 DPI). Additionally, at 21 DPI, 50% and 75% of mice exhibited periosteal bone proliferation affecting the metatarsal bones, apparent via histology and μCT, respectively. μCT analysis did not reveal any alterations in trabecular bone volume measurements in C57BL/6J mice. Novel lesions demonstrated in IRF 3/7 -/- -/- mice at 5 DPI included focal regions of cartilage necrosis (20%), periosteal necrosis (66%), and multifocal ischemic bone marrow necrosis (100%). Contralateral feet in 100% of mice of both strains had similar, though milder lesions. Additionally, comparison of control IRF 3/7 -/- -/- and wild-type C57BL/6J mice demonstrated differences in cortical bone. These experiments demonstrate novel manifestations of disease similar to those occurring in humans, adding insight into disease pathogenesis, and representing new potential targets for therapeutic interventions. Additionally, results demonstrate the utility of μCT in studies of bone and joint pathology and illustrate differences in bone dynamics between mouse strains. PMID:27182740

    2013-07-01

    In this fourth edition of Combined Scintigraphic and Radiographic Diagnosis of Bone and Joint Diseases, the text has been thoroughly amended, updated, and partially rearranged to reflect the latest advances. In addition to discussing the role of pinhole imaging in the range of disorders previously covered, the new edition pays detailed attention to the novel diagnostic use of gamma correction pinhole bone scan in a broad spectrum of skeletal disorders, including physical, traumatic, and sports injuries, infectious and non-infectious bone diseases, benign and malignant bone tumors, and soft tissue diseases. A large number of state of the art pinhole scans and corroborative CT, MRI, and/or ultrasound images are presented side by side. The book has been enlarged to encompass various new topics, including occult fractures; cervical sprain and whiplash trauma; bone marrow edema; microfractures of trabeculae; evident, gaping, and stress fractures; and differential diagnosis.

Estas aes estruturam-se a partir da deteco da hipertenso arterial na populao adulta atendida no servio e do controle dos nveis pressricos nos indivduos portadores de HAS, incluindo outros fatores de risco conhecidos, bem como tratamento de eventuais complicaes. Analisaram-se 3.793 usurios que compareceram pelo menos uma vez consulta mdica no servio de Assistncia ao Adulto de um Centro de Sade-Escola, do Municpio de So Paulo (Brasil, no perodo de 1 de junho de 1990 a 31 de maio de 1991. Para cada um dos usurios foram considerados os diagnsticos realizados, bem como a concentrao de cada modalidade de consulta realizada (pronto-atendimento e consulta agendada. Destes, 839 eram portadores de hipertenso arterial e/ou diabete e foram agrupados em quatro categorias: os exclusivamente hipertensos, os hipertensos com outra doena crnica associada (exceto diabete, os diabticos e os diabticos com hipertenso arterial. Os resultados deste estudo mostraram: 1 baixa cobertura de indivduos hipertensos e diabticos em atendimento no servio, quando se considera a populao atendida pelo Centro de Sade; 2 a existncia de pacientes diagnosticados como hipertensos em consultas de pronto-atendimento, que no retornaram ao Centro de Sade para seguimento mdico programtico, apontando para dificuldades na captao efetiva destes indivduos. Esta "perda" deveu-se tanto a faltas dos pacientes s consultas agendadas para seu seguimento quanto ao no agendamento de consultas de seguimento por parte do servio; 3 para os pacientes que aderiram ao seguimento, a concentrao de consultas mdicas e a concentrao de faltas apresentaram nmeros compatveis com a proposta de agendamento trimestral; 4 a categoria dos exclusivamente hipertensos apresentou, quando comparada com as demais, menor concentrao de consultas e maior proporo de faltas por consulta agendada. Discutem-se os limites das aes baseadas no "enfoque de risco" para controle de doenas crnico-degenerativas em populao.The efficacy of health actions, related to arterial hypertension and used as a strategy to decrease morbi-mortality due to cardiovascular diseases, in accordance with the "risk approach" and carried out in a Primary Health Care Clinic is assessed. These actions are based on the detection of arterial hypertension in the adult population attended at the Clinic and on the control of blood pressure levels in hypertensive individuals in which other known risk factors continue to be controlled, as well as on further treatment of eventual complications. Data relating to the 3,793 patients who were attended at least once by doctors of the adult sector of a training health-center located in S. Paulo county (Brazil during the period from June 1990 to May 1991, inclusive, were evaluated. This evaluation was made according to each diagnosis undertaken as well as to the concentration of each type of consultation whether occasional, or follow-up. Of these 3,793 patients analysed, 839 presented arterial hypertension and/or diabetes, and were grouped into four categories: the exclusively hypertensive, the hipertensive with other associated chronic diseases (except diabetes, the diabetic and the diabetic with arterial hypertension. The results of this study brougth the following aspects to light: 1 The low coverage of hypertensive individuals and diabetics being attended by the health service when only the population attended by the health service is taken into consideration. 2 The incidence of patients diagnosed as hypertensive in occasional consultations who did not return to the health service for medical follow-up indicates the difficulties involved in attracting such individuals permanently.

    Full Text Available Study Design: Retrospective cohort study. Purpose: Facet joints are considered a common source of chronic low-back pain. To determine whether pathogens related to the facet joint arthritis have any effect on treatment failure. Materials and Methods: Facet joint injection was applied to 94 patients treated at our hospital between 2011 and 2012 (mean age 59.5 years; 80 women and 14 men. For the purpose of analysis, the patients were divided into two groups. Patients who only had facet hypertrophy were placed in group A (47 patients, 41 women and 6 men, mean age 55.3 years and patients who had any additional major pathology to facet hypertrophy were placed in group B (47 patients, 39 women and 8 men, mean age 58.9 years. Injections were applied around the facet joint under surgical conditions utilizing fluoroscopy device guidance. A mixture of methylprednisolone and lidocaine was used as the injection ingredient. Results: In terms of Oswestry Disability Index (ODI and visual analog scale (VAS scores, no significant difference was found between preinjection and immediate postinjection values in both groups, and the scores of group A patients were significantly lower (P < 0.005 compared with that of group B patients at the end of the third, sixth, and twelfth month. Conclusion: For low-back pain caused by facet hypertrophy, steroid injection around the facet joint is an effective treatment, but if there is an existing major pathology, it is not as effective.

    Ten years ago, the diagnosis discussion of a dementia case for the old patient was limited to two pathologies: the Alzheimer illness and the Pick illness. During these last years, the frame of these primary degenerative dementia has fallen into pieces. The different diseases and the results got with single photon emission computed tomography are discussed. for example: fronto-temporal dementia, primary progressive aphasia, progressive apraxia, visio-spatial dysfunction, dementia at Lewy's bodies, or cortico-basal degeneration.

  3. Fusion of the distal intertarsal and tarsometatarsal joints in the horse using intra-articular sodium monoiodoacetate

    Six normal horses received 3 intra-articular injections of sodium monoiodoacetate (MIA) in the distal intertarsal (DIT) and tarsometatarsal (TMT) joints of one hindlimb. Injections were at three week intervals, and post injection pain was controlled with routine administration of phenylbutazone for five days following each injection. All horses underwent a gradually increasing exercise programme consisting of walking and trotting beginning one week after the first injection and continuing for 24 weeks. All treated joints showed increasingly severe radiographic evidence of degenerative joint disease with time. Clinical signs were mild or absent during exercise. All treated joints showed radiographic and histological evidence of fusion 24 weeks after the first injection. Amount of radiographic fusion ranged from 54.49 per cent to 88.64 per cent of the joint space. Histologically, the joint space that appeared radiographically fused was filled mainly with woven and lamellar bone. Fibrocartilage and fibrous tissue was seen frequently in the transition between fused and unfused areas. Articular cartilage in unfused areas was thin, fibrillated, hypocellular and histochemically showed diminished proteoglycan content. Existing joint space was filled with fibrin and necrotic, acellular chondroid matrix. We conclude that MIA will produce fusion of the DIT and TMT joints of normal horses in 24 weeks, and may offer a relatively easy, inexpensive and non-invasive treatment for distal tarsal osteoarthritis in the horse

    Full Text Available Chronic obstructive pulmonary disease (COPD is a major public health problem in India. Although several International guidelines for diagnosis and management of COPD are available, yet there are lot of gaps in recognition and management of COPD in India due to vast differences in availability and affordability of healthcare facilities across the country. The Indian Chest Society (ICS and the National College of Chest Physicians (NCCP of India have joined hands to come out with these evidence-based guidelines to help the physicians at all levels of healthcare to diagnose and manage COPD in a scientific manner. Besides the International literature, the Indian studies were specifically analyzed to arrive at simple and practical recommendations. The evidence is presented under these five headings: (a definitions, epidemiology, and disease burden; (b disease assessment and diagnosis; (c pharmacologic management of stable COPD; (d management of acute exacerbations; and (e nonpharmacologic and preventive measures. The modified grade system was used for classifying the quality of evidence as 1, 2, 3, or usual practice point (UPP. The strength of recommendation was graded as A or B depending upon the level of evidence.

  7. How can calcium pyrophosphate crystals induce inflammation in hypophosphatasia or chronic inflammatory joint diseases?

    Beck, C; Morbach, H; Richl, P; Stenzel, M; Girschick, H J

    2009-01-01

    Hypophosphatasia (HP) is a rare inborn error of bone and mineral metabolism characterized by a defect in the tissue non-specific alkaline phosphatase (TNSALP) gene. Calcium pyrophosphate dihydrate (CPPD) crystals are known to accumulate as substrates of TNSALP in tissues and joints of patients with HP. In CPPD-induced arthritis these crystals are known to induce an inflammatory response. HP patients do suffer from pain in their lower extremities. However, it is not clear whether CPPD crystals contribute to these musculoskeletal complaints in HP. As long as there is no curative treatment of HP, symptomatic treatment in order to improve clinical features, especially with regard to pain and physical activity, is of major interest to the patients. Knowledge of the mechanisms underlying crystal-induced cell activation, however, is limited. Here we describe recent advances in elucidating the signal transduction pathways activated by CPPD crystals as endogenous "danger signals". Recent investigations provided evidence that Toll/interleukin-1 receptor (TIR) domain containing receptors including Toll-like receptors (TLRs) and interleukin-1 receptor (IL-1R), as well as the triggering receptor expressed on myeloid cells 1 (TREM-1) and the NACHT-leucin rich repeat and pyrin-domain-containing protein (NALP3) containing inflammasome are essentially involved in acute CPPD crystal-induced inflammation. These receptors are considered in part as components of the innate immune system. Further studies are needed to improve our understanding of the pathophysiological mechanisms leading to inflammation and tissue destruction associated with deposition of microcrystals. They might support the development of new therapeutic strategies for crystal-induced inflammation. Eventually, patients with HP might as well profit from such strategies addressing these metabolic disorders secondary to the gene defect. PMID:18821074

    Objective: To describe the main indications and the technical steps to perform ultrasound guided procedures in patients with rheumatic diseases. To access procedures accuracy, safety and effectiveness. Materials and methods: 27 patients with pain related to articular complications of rheumatic diseases and according to previous radiographic or US exam were submitted to several US-guided procedures. 42% of patients (n = 11) had rheumatoid arthritis, 11% (n = 3) spondyloarthropathies, 18% (n = 5) psoriatic arthritis, 15% (n = 4) undifferentiated arthritis, 3% (n = 1) Sjoegren syndrome and 11% (n = 3) had gout. Described procedures are synovial biopsies, intra-articular injections of corticosteroids, radiation synovectomy and synovial cysts drainage procedures. When a therapeutical procedure was made, patients were evaluated by 2 rheumatologists. Corticosteroids used were Prednisolone and Triamcinolone. Yttrium-90 was used for synovectomy. Results: In all cases success was achieved with correct needle placement inside the joint. After injection/aspiration symptoms successfully solved with all patients improving their health status. No complications were recorded during follow-up period. Conclusions: US-guidance is very reliable to afford a safety procedure always checking the injection, biopsy or aspiration. Guided-biopsy has high success rates obtaining several samples. Thus is also possible to use more powerful/long acting therapeutic drugs aggressive to extra-articular structures avoiding complications.

  10. Current Insights into the Joint Genetic Basis of Type 2 Diabetes and Coronary Heart Disease

    Dauriz, Marco; Meigs, James B.

    2014-01-01

    The large-scale genome-wide association studies conducted so far identified numerous allelic variants associated with type 2 diabetes (T2D), coronary heart disease (CHD) and related cardiometabolic traits. Many T2D- and some CHD-risk loci are also linked with metabolic traits that are hallmarks of insulin resistance (lipid profile, abdominal adiposity). Chromosome 9p21.3 and 2q36.3 are the most consistently replicated loci appearing to share genetic risk for both T2D and CHD. Although many gl...

    2012-05-01

    The purpose was to compare radiographic parameters with a sex-matched and age-matched control group at the onset of disease and at skeletal maturity. The study comprised 143 patients with Legg-Calvé-Perthes disease, treated using a Thomas splint. Wiberg's centre-edge angle and the acetabular index angle were applied. The age at diagnosis was 6.6 years with no difference between boys and girls. At the time of diagnosis, the centre-edge angle was decreased from 18° in the control group to 10° in the affected hip. The age at follow-up was 16 (SD 2) years for the boys and 15 (SD 3) years for the girls. At the time of skeletal maturity, the centre-edge angle was decreased and the acetabular index angle increased in the affected hip and the nonaffected hip in Stulberg class III/IV/V hips compared with the control group. Initially radiographic changes only occur on the affected hip. At skeletal maturity both hips show radiographic changes. PMID:22186707

    1996-01-01

    The athletic activity of the adult U.S. population has increased markedly in the last 20 years. To evaluate the possible long-term effects of such activity on the cervical and lumbar spine, we studied a group of asymptomatic currently very active lifelong male athletes over age 40 (41-69 years old, av. age 53). Nineteen active, lifelong male athletes were studied with MRI and the results compared with previous imaging studies of other populations. An athletic history and a spine history were also taken. Evidence of asymptomatic degenerative spine disease was similar to that seen in published series of other populations. Degenerative changes including disk protrusion and herniation, spondylosis, and spinal stenosis were present and increased in incidence with increasing patient age. In this group, all MRI findings proved to be asymptomatic and did not limit athletic activity. The incidence of lumbar degenerative changes in our study population of older male athletes was similar to those seen in other populations. 14 refs., 8 figs., 1 tab.

    1986-08-01

    Arthrodesis is currently the treatment of choice for symptomatic degenerative arthropathy of the ankle. Thirty-seven patients underwent arthrodesis for post-traumatic disorders using either a Hoffmann external fixator or a Calandruccio frame. There was degenerative joint disease in 19 (51%), septic arthritis in 11 (30%), severe comminution in five (14%), and uncontrollable equinus in two (5%). The patients were divided into two groups. Twenty-six (70%) were considered to have sustained high energy open or comminuted injuries and 11 (30%), low energy injuries. Twenty-nine (78%) achieved a radiologic fusion following one operation. Four eventually united with further surgery for a final arthrodesis rate of 89%. In the high energy group 18 of 26 (69%) achieved primary fusion. Four united with additional surgery for a final arthrodesis rate of 85%. Two of these required subsequent amputations and two others, a triple arthrodesis which also failed to control chronic pain. Thus, a total of 18 of the 26 patients (69%) achieved a successful result. Also included in the high energy group were three patients with uncontrolled sepsis who underwent amputation before union occurred and one with a painful non-union. All 11 of the patients (100%) who originally sustained low energy injuries achieved a successful arthrodesis. The most common complication was in pin tract infection requiring incision, drainage, and oral antibiotics in 16 patients (43%). None of these progressed to chronic osteomyelitis. PMID:3091461

    Full Text Available INTRODUÇÃO: na última década, a instrumentação interespinhosa vem sendo mais frequentemente utilizada. Apesar dos inúmeros artigos publicados em revistas internacionais de reconhecido mérito científico, são escassas as referências à modificação da altura do disco no segmento tratado, secundária àquela instrumentação. OBJECTIVO: quantificar uma eventual modificação da altura discal decorrente da aplicação de instrumentação interespinhosa (DIAM - Cousin-Biotech - Medtronic Sofamor Danek Inc©. MÉTODOS: o autor avalia um grupo de 20 pacientes com patologia degenerativa da coluna lombar e os seguintes critérios de inclusão: idade >40 e 6; Oswestry Disability Index (ODI >30; Zung Depression Rating Scale INTRODUCCIÓN: la instrumentación interespinosa tiene sido empleada con creciente frecuencia en la última década. Pero, apesar de las numerosas publicaciones científicas hechas en jornales científicos de reconocido mérito internacional, se han producido muy escasas referencias a una hipotética modificación de la altura discal dependiente de la técnica. OBJETIVO: cuantificar una eventual modificación de la altura discal inherente a la aplicación de instrumentación interespinosa. MÉTODOS: el autor hace una evaluación de un grupo de 20 pacientes con patología degenerativa de la columna lumbar, y diversos criterios de inclusión, a saber: edad >40 y 6; Oswestry Disability Index >30; Zung Depression Rating Scale INTRODUCTION: the use of interspinous instrumentation has been increasing in the last decade. However, in spite of the numerous papers seen in relevant scientific publications, there are very few references to an eventual disc height variation in the instrumented segment. OBJECTIVE: to certify eventual changes in disk height after interspinous instrumentation (DIAM - Cousin-Biotech - Medtronic Sofamor Danek Inc©. METHODS: the author evaluated 20 patients with degenerative lumbar disease and the following criteria: age >40 and 6; Oswestry Inability Index >30; Zung Depression Rating Scale <39; Modified Somatic Perception Questionnaire <15; degenerative bone disease grade 2 and 3 according to Benzel classification and degenerative disk disease grade 3 and 4 according to Pfirmann classification. Using a special formula and a computer image program (Adobe Photoshop 9.0 CS2, side radiograms of the lumbar spine in orthostatic position and with 70% amplification were obtained pre-surgery and two years after surgery. RESULTS: after applying the mentioned formula, the results showed an increased global disk height average 1.53 mm, with a standard deviation of 1.09 mm and p=0.0002. However, there was a large increase (0.45 mm in posterior disk height (p=0.0002 when compared with anterior measurement (p=0.001 pointing out a slight kyphosing effect related to the instrumentation. CONCLUSIONS: in Benzel grade 2 and 3 and Pfirmann grade 3 and 4 degenerative lumbar disease, the use of an interspinous system seemed to be able to increase disk height and to improve neural canal dimensions.

    Full Text Available Ultrasound image is the primary (input information for every ultrasonic examination. Since being used in ultrasound images analysis the both knowledge-base decision support and content-based image retrieval techniques have their own restrictions, the combination of these techniques looks promissory for covering the restrictions of one by advances of another. In this work we have focused on implementation of the proposed combination in the frame of CASAD (Computer-Aided Sonography of Abdominal Diseases system for supplying the ultrasound examiner with a diagnostic-assistant tool based on a data warehouse of standard referenced images. This warehouse serves: to manifest the diagnosis when the ecographist specifies the pathology and then looks through corresponding images to verify his opinion; to suggest a second opinion by automatic analysis of the annotation of relevant images that were assessed from the repository using content-based image retrieval.

  17. Familial disease, the HLA-DRB1 shared epitope and anti-CCP antibodies influence time at appearance of substantial joint damage in rheumatoid arthritis.

    Rheumatoid arthritis (RA) progresses more rapidly in some patients than in others and diverse factors influence radiographic progression in a specific population. Thus, we searched for variables that are associated with an early appearance of substantial joint damage in patients with RA by using radiographic assessments. A cohort of 157 consecutively enrolled Colombian RA patients was followed for an average of 3.2+/-3.1 years. Information on patient demographics and cumulative clinical and laboratory manifestations over the course of the disease was registered, including family history of RA in first-degree relatives, extra-articular manifestations, rheumatoid factor, anti-CCP3 antibodies, TNF single nucleotide polymorphism at -308 position, and HLA-DRB1 status. Radiographs were scored according to the Sharp-van der Heijde method. Survival analyses of the time at appearance of substantial joint damage were performed by using Weibull models. A review of literature about the influence of familial RA on the progression of disease was done. Our results show that family history of RA is consistently associated with joint damage (i.e. erosive and joint narrowing disease). This effect was not found in all the populations reviewed. In addition, we confirm the effect of HLA-DRB1 shared epitope and anti-CCP seropositivity on erosive disease. Family history of RA is a key risk factor for joint damage and depends on the investigated population because variations in both additive and non-additive genetic factors and the environmental variance are specific to the population. Our results emphasize the usefulness of assessing familial disease, testing anti-CCP antibodies and genotyping HLA-DRB1 gene in patients with RA because these factors may be used to predict clinical outcomes and guide therapeutic interventions.

    Purpose: The purpose of this study was to analyze potential quantitative and qualitative changes of the knee cartilage and joint indicative of early posttraumatic OA 4 years after ACL-reconstruction and to correlate the MRI-findings with the clinical outcome (CO). Materials and Methods: 1.5 T MRI-scans were performed on 9 patients post-op and 4 years later. Using a high-resolution T 1-w-fs-FLASH-3D-sequence cartilage volume (cVol) and thickness (mTh) were quantified. Using standard PD-w fs and T 1-w sequences qualitative changes of the joint structures were analyzed based on the WORMS-score. CO was rated by an orthopaedic surgeon using Lysholm-score, OAK-score, Tegner-activity-score (TAS), and Arthrometer KT-1000 testing. Results: Mean changes of cVol were -1.8 % (range: -5.9 %; + 0.7 %) and of mTh -0.8 % (range: -3.0 %; + 1.1 %). No significant change (95 %-CI) could be identified for any compartment. Three patients developed new peripatellar ostheophytes, acute trauma related changes mostly decreased. Mean outcome of Lysholm-score and OAK-score were 90 pts and 86 pts, mean TAS was 4.3 pts. Average maximum tibial translation reached 5.2 mm comparing to 6.7 mm on the healthy contralateral side. Conclusion: Despite a tendency towards decreased cVol and mTh 4 years after ACL-reconstruction qMRI revealed no significant cartilage loss. Newly developing osteophytes did not match with the observed good CO. This small pilot study motivates future quantitative and qualitative-structural MRI-based assessment of articular cartilage and other joint structures in order to improve diagnostic tools for the detection of early OA.

    Full Text Available La enfermedad valvular degenerativa es la principal anormalidad cardiovascular de los perros. La lesión en el aparato valvular consiste en una infiltración de mucopolisacaridos en la matriz extracelular de las aletas valvulares y las cuerdas tendinosas, lo que ocasiona una regurgitación de sangre hacia las aurículas. Esta disminución del gasto cardiaco activa mecanismos neurohormonales que originan una remodelación ventricular, causante de la aparición de signos clínicos y la muerte. Un grupo internacional de expertos en medicina interna ha propuesto nuevos lineamientos para su diagnóstico y adecuado tratamiento en cada nivel.

    Teorema and indometacin were administered to patients with degenerative and inflammatory joint diseases and degenerative vertebral column diseases for a period of 21 days. 24 patients were included in the 3 groups distinguished by diagnostic criteria. The daily Teorema dose was 420 mg in 21 cases and 210 mg in 3 cases; that of indometacin was 150 mg in 22 cases and 75 mg in 2 cases. Both drugs were given orally as capsules (25 mg indometacin/capsule and 70 mg Teorema/capsule). Both compounds produced a highly significant improvement of symptoms. Laboratory tests at regular intervals failed to reveal any substantial deviations from normal in both treatment groups. In conclusion, the results of the double blind trial suggest that Teorema, a new anti-inflammatory substance, when administered at a dose of approximately 420 mg/day, produces a beneficial effect in many rheumatoid conditions, while causing remarkably few side effects.
