Haemophilia disorders are characterised by a blood coagulation anomaly leading to prolonged and excessive bleeding. Imaging provides an essential role in the investigation of both the musculoskeletal and the non-musculoskeletal complications of haemophilia. Our institution is home to a large tertiary referral centre for haemophilia treatment. Using our broad experience, we present a multi-modality pictorial review of the musculoskeletal manifestations of haemophilia, including haemophilic arthropathy, intra-muscular haemorrhage and haemophilic pseudotumour. The main imaging features of haemophilic arthropathy are described, including synovial hypertrophy, haemosiderin deposition, sub-chondral cyst formation and loss of joint space. (orig.)

Although enormous progress has been made in recent years in the field of haemophilia, some problems still await solution, such as the risk of sudden haemorrhage, the sequelae of haemophilic arthropathy and social activities. We, therefore, carried out a case-control study in which some psychological dimensions (social expectations, tendency to depression, state of anxiety and self-esteem) were evaluated in a group of 60 haemophiliacs. A control group was formed of 78 healthy subjects matched for age, socio-economic class and level of education. The methodology used was the administration of self-assessment questionnaires which investigate and provide a quantitative measure of psychological dimensions. The results can be subjected to statistical analysis. Three self-assessment questionnaires were used: (i) the Marlowe-Crowne scale, (ii) the Beck Inventory version modified by Cusinato and (iii) the S.T.A.I.-form. Our aim was to evaluate: (i) whether there are significant differences in the considered psychological aspects between haemophiliacs and healthy subjects; (ii) whether there is a significant correlation between the psychological dimensions considered in the haemophiliacs and in the healthy subjects. The results showed that the haemophiliacs have a good psychological adaptation to their disease with the exception of their greater tendency to have less self-esteem than do the healthy subjects. As far as concerns the second aim, we found than self-esteem correlated with all the psychological variables investigated. This information could indicate the enormous importance that the psychological variable 'self-esteem' plays in haemophiliacs with respect to whether or not they develop depressive disorders and/or anxiety states.

Although haemophilia is a relatively rare hereditary disease, and is curable by blood products, the psychological and social problems of haemophilic patients and of their families are always serious. Anxiety for the risks of bleedings and the fear for infections transmitted by blood products cause stress and difficulty in coping with the situation. The aim of this paper is to assess resources, stress, and coping in parents with a haemophilic child. In order to measure the dimensions related to family stress and resources, social desirability, tendency to depression, and anxiety, the subjects were administered the short-form of the Questionnaire on Resources and Stress by Friedrich et al. revised by Saviolo & Cristante, along with the Social Desirability Scale, the Beck Depression Inventory, and the Ipat Anxiety Scale. The subjects of this study were 20 couples who were the parents of haemophilic sons. We analysed how the parents perceived the behavioural characteristics of their child, the differences between mothers and fathers in the questionnaire scores, and the correlation among the considered dimensions. The results show that the parents paid great attention to the problems of their sons, but mothers were more depressed and anxious about the disease of their child.

The sesamoid index was originally described as an aid to the diagnosis of acromegaly. We performed this study to assess the value of the thumb sesamoid index in the diagnosis of psoriatic arthropathy. Retrospective measurement of the sesamoid index (length x width of the medial thumb sesamoid), along with the age and sex were recorded for patients as described below. Patients with psoriasis were subdivided into those with or without radiographic evidence of hand arthropathy. Fifty-nine consecutive patients attending rheumatology clinics with arthralgia and psoriasis were studied. Comparison groups with radiographic evidence of rheumatoid arthritis (52 patients), osteoarthritis (44) or normal hands (55) were also recorded. Twenty-one of 59 patients with psoriasis and arthropathy had a sesamoid index >40, compared with two of 52 with rheumatoid arthritis, none of 44 with osteoarthritis and none of 55 normals. Psoriatic arthropathy is a recognised cause of bone enlargement, usually in the phalanges due to periostitis and proliferative enthesopathy. We have confirmed that psoriatic hand arthropathy can cause significant enlargement of the thumb sesamoids, a feature which is easily quantified and may assist diagnosis. (orig.)

Full Text Available Sébastien Lobet,1,2 Cedric Hermans,1 Catherine Lambert1 1Hemostasis-Thrombosis Unit, Division of Hematology, 2Division of Physical Medicine and Rehabilitation, Cliniques Universitaires Saint-Luc, Brussels, Belgium Abstract: Hemophilia is a hematological disorder characterized by a partial or complete deficiency of clotting factor VIII or IX. Its bleeding complications primarily affect the musculoskeletal system. Hemarthrosis is a major hemophilia-related complication, responsible for a particularly debilitating chronic arthropathy, in the long term. In addition to clotting factor concentrates, usually prescribed by the hematologist, managing acute hemarthrosis and chronic arthropathy requires a close collaboration between the orthopedic surgeon and physiotherapist. This collaboration, comprising a coagulation and musculoskeletal specialist, is key to effectively preventing hemarthrosis, managing acute joint bleeding episodes, assessing joint function, and actively treating chronic arthropathy. This paper reviews, from a practical point of view, the pathophysiology, clinical manifestations, and treatment of hemarthrosis and chronic hemophilia-induced arthropathy for hematologists, orthopedic surgeons, and physiotherapists.

A relationship between haemophilia and osteoporosis has been suggested, leading to the initiative for a larger study assessing this issue. Bone mineral density (BMD) was measured by osteodensitometry using dual energy X-ray absorptiometry (DEXA) in 62 male patients with severe haemophilia A; mean age 41 +/- 13.1 years, mean body mass index (BMI) 23.5 +/- 3.6 kg m(-2). Using the clinical score suggested by the World Federation of Hemophilia, all patients were assessed to determine the severity of their arthropathy. A reduced BMD defined as osteopenia and osteoporosis by World Health Organization criteria was detected in 27/62 (43.5%) and 16/62 (25.8%) patients, respectively. Fifty-five of sixty-two (88.7%) patients suffered from haemophilic arthropathy. An increased number of affected joints and/or an increased severity were associated with lower BMD in the neck of femur. Pronounced muscle atrophy and loss of joint movement were also associated with low BMD. Furthermore, hepatitis C, low BMI and age were found to be additional risk factors for reduced BMD in the haemophiliac. Our data shows that in haemophilic patients osteoporosis represents a frequent concomitant observation. The main cause for reduced bone mass in the haemophiliac is most probably the haemophilic arthropathy being typically associated with chronic pain and loss of joint function subsequently leading to inactivity. Further studies including control groups are necessary to elucidate the impact of comorbidities such as hepatitis C or HIV on the development of osteoporosis in the haemophiliac.

Full Text Available We report the unusual case of a patient with acromegalic arthropathy who presented with severe shoulder arthrosis with marked osteophytosis. This patient is currently pain-free and has good shoulder function 4 years following a Copeland shoulder hemiarthroplasty. Acromegaly is a rare condition of growth hormone oversecretion, but arthropathy is a common feature of the natural history of the disease. This is the first published case report of the outcome of shoulder arthroplasty in a patient with acromegalic arthropathy and demonstrated that a good result can be obtained in this patient.

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 [fr

Full Text Available Haemophilia is a rare haematological disease characterized by prolonged bleeding due to deficiency of coagulating factor 8 and factor 9. This is cross sectional study carried out at paediatric haematology unit Al-Azhar university hospital, Cairo, Egypt, and paediatric haematology unit of El Mabarah-Hospital-Health Insurance Organization, Zagazig, Egypt, during March 2014 to March 2016. One hundred male patients were screened for hepatitis (A, B, and C. Mean age was 11.47 ± 4.4 years old. About 95% with haemophilia A, 4% haemophilia B and 1 patient had combined haemophilia A and family history of hepatitis was 21%. Consanguinity was 28%. Similar condition in the family was 36%. Ecchymosis as clinical manifestation was 64%, haemarthrosis was 62% and jaundice detected in 35% of cases. Severity was mild 20%, moderate 47% and severe was 33%. Most affected joint was knee joint and represented 41%. Blood transfusion, cryoprecipitate were major risk factors for transmitting of hepatitis C positive cases. HAV was 7%, HBV was 0% and hepatitis C was 65%. Conclusion: HCV is still high in haemophilic and represent a major problem. Recommendation: Early detection, treatment, and further investigation of hepatitis C virus in haemophilic children.

Hereditary pyrophosphate arthropathy has been observed in three Swedish families and in a few other caucasian populations. The inheritance is most probably autosomal dominant with a variable penetrance. The most severe cases have been found in homozygotes among isolates of immigrants in Slovakia and Chile. Studies on genetic and etio-pathogenetic factors in hereditary pyrophosphate arthropathy, and the utilization of new diagnostic techniques for crystal identification, are important approaches towards a further understanding of the disease.

Full text: Joint disorders are the major cause of disabilities. It is a threat to a person's social, economical, physical and psychological health. Besides infectious and degenerative arthritic disorders, hemophiliac arthropathy cause major role in crippling young individuals and needs special attention. Hemophilia is a common clotting disorder due to factor VIII (Hemophilia A) and IX (Hemophilia B) deficiency. More than 50% of these patients suffer from chronic hemophilic arthropathy. The incidence of hemophiliac arthropathy is increasing in Pakistan due to lack of facilities of factor VIII replacement and its high cost for long-term treatment. Different treatment options like chemical synovectomy and surgical removal of synovium are available to treat these patients. Due to high morbidity of surgical procedures and severe pain during chemical synovectomy, we started radiation synovectomy in our center. In this study we have evaluated the role of radiation synovectomy using Re-188 Tin colloid and P-32 colloid in hemophiliac children with grades I and II arthropathy. Intraarticular injection was administered to large joints of lower and upper limbs under strict aseptic conditions. Immediate and delayed static images were acquired to evaluate the leakage to regional lymph nodes. Response to treatment was assessed on follow up with respect to improvement in pain, joint swelling, range of movement, number of episodes of subsequent haemarthrosis and amount of factor VII requirements. In conclusion, radiation synovectomy proved to be effective; it improved the range of motion and is better tolerated by patients due to less pain during the post- therapy period. Significant reduction in factor VIII replacement improved the management of haemophiliac arthropathy and results proved the cost effectiveness of radiation synovectomy. (author)

Radiological residua of healed diabetic arthropathies

Reinhardt, K.

1981-12-01

Diabetic arthropathy is a relatively rare manifestation of neuropathic disease, occurring in fewer than 5% of cases. Abnormalities of this type are confined largely to the small joints of the feet, although the larger joints of the lower limbs and the spine occasionally are affected. Some lesions, particularly in the feet, repair spontaneously, leaving radiological residua sufficiently characteristic to prompt suspicion of an unrecognised diabetic state. These include deformity of the head of the second metatarsal (akin to a Freiberg lesion), shortening of the great toe, painless deforming arthrosis of the knee, and ankylosis of interphalangeal joints. In the presence of these signs the patient should be interrogated concerning diabetes and blood sugar estimates, with provocation if necessary, obtained. Should such a diagnosis be sustained, appropriate protective measures may be undertaken to avoid a relapse of the arthropathy.

Neonatal onset multisystem inflammatory disease (NOMID), an autoinflammatory disease, is characterized by fever, chronic urticarial rash, CNS manifestations, and arthropathy. Approximately 50% of patients with NOMID have de novo missense mutations in CIAS1, which is associated with modulation of the IL-1b and apoptotic pathways. Approximately 60% of NOMID patients have prominent arthropathy, most commonly involving the knees, the cause of which remains poorly understood. To more fully describe the findings of NOMID arthropathy on MRI and radiography and to provide a better understanding of the origin of the bony lesions. We imaged 20 patients with NOMID to further investigate NOMID-associated bony lesions. Bony abnormalities were seen in the knees of 11/20 patients. The knee findings included enlarged, deformed femora and patellae in all and tibiae in the majority, without evidence of synovitis. Some patients had other joint involvement. Most had short stature and valgus or varus knee deformities. No association was noted between bony abnormalities and CIAS1 mutations. The abnormalities appeared to be the result of a mass-producing process. The resulting heterogeneously calcified masses appeared to originate in the physis and deformed the adjacent metaphysis and epiphysis. These findings suggest that the arthropathy of NOMID is the result of abnormal endochondral bone growth. Further investigation is needed to determine whether this deformity is triggered by inflammation early in development or by CIAS1 mutations causing abnormal chondrocyte apoptosis. (orig.)

Haemophilic pseudotumour (HP) is a rare but very serious complication of haemophilia. HP affects mainly patients with severe haemophilia and those who have developed antibodies to factor VIII or factor IX. We report on a 45-year-old man with haemophilia A and high titres of inhibitors who developed an extensive HP with progressive destruction of the right ilium over a period of 12 years. The different therapeutic options (conservative management by replacement therapy, surgical approach, radiotherapy, percutaneous evacuation with secondary refilled cavity and transcatheter arterial embolization) are reviewed.

Lead arthropathy is a well-known complication of gunshot injuries with retained intra-articular bullets. Although several previous reports have discussed the radiological findings of this entity, computed tomography (CT) and magnetic resonance imaging (MRI) findings have never been described before in this setting. In this paper the authors review the imaging findings of 11 patients with lead arthropathy (1 of whom had clinical signs of lead poisoning as well), all of them studied by means of radiographs. In addition, non-enhanced CT scans were obtained in 3 patients and gadolinium-enhanced MRI in 1. Classic findings of intra-articular speckled lead deposits (occasionally with a ''lead arthrogram'' appearance), joint space narrowing and preserved bone density were found at radiographs in the great majority of cases. Furthermore, extension of intra-articular lead to adjacent tendon sheaths was observed in almost half of the patients, an observation rarely reported in the literature. CT scans and MRI, in their turn, were superior with regard to soft tissue abnormalities, accurately depicting joint effusion and the thickened synovium with lead particles embedded in it. Post-gadolinium MRI had the advantage of showing the enhancement pattern of the inflamed synovium and associated bone marrow edema pattern. Although it is not possible to establish the role of axial imaging in lead arthropathy from the small number of cases studied, this initial experience shows that both methods hold promise in this setting and may be useful, at least in selected cases.

Although physiotherapy has demonstrated effectiveness in preventing ankle arthropathy compared to prophylaxis treatment from early ages, there have been no conclusive studies examining physiotherapy intervention once hemophilic arthropathy of the ankle has been established. The aim of this study was to evaluate the effectiveness of two physiotherapy interventions, in patients with hemophilic arthropathy of the ankle that had not been operated on previously. Nine patients with hemophilia (mean age of 35.7 SD 11.9 years) were randomized to a mobilization group (n = 5) and manual therapy group (n = 4). The two physiotherapy interventions were: (1) passive mobilization and stretching; and (2) manual orthopaedic therapy, both with proprioception training. The study lasted for six weeks, with two sessions a week. Ankle mobility and pain perception, lower limb proprioception and quality of life were the outcome measures. Both treatments improved all ankle movements (p ankle arthropathy. No haemarthrosis was recorded during treatment or during the follow-up period.

The aim of this study was to investigate atherosclerotic load at the lower extremity in patients with diabetic foot and charcot neuro-arthropathy and compare them with patients with diabetic foot without charcot neuro-arthropathy. This retrospective study consists of 78 patients with diabetic foot who had lower extremity angiography with antegrade approach. All patients were classified into two groups; neuro ischemic wounds with charcot neuro-arthropathy (30/78) and without charcot neuro-arthropathy (48/78).Atherosclerotic load at the side of diabetic foot was determined by using the Bollinger angiogram scoring method. Comparison of atherosclerotic load between the two groups was performed. The mean of total and infrapopliteal level angiogram scoring of all patients was 33.3 (standard deviation, sd:±17.2) and 29.3 (sd:±15.6), respectively. The mean of total and infrapopliteal level angiogram scoring of neuroischemic wounds with charcot neuro-arthropathy group was 18.1 (sd:±11.6) and 15.7 (sd:±10.4), respectively. The mean of total and infrapopliteal level angiogram scoring of neuroischemic wounds without charcot neuro-arthropathy group was 42.8 (sd:±12.7) and 37.7 (sd:±12.0), respectively.

Ossifying enthesites present an undeniable diagnostic value in every chronic inflammatory rheumatism at an early stage, not only in adults but also in children. Bony scintigraphy discovers them in most localizations at a preradiological stage, as soon as they cause pain. The scanner examination enables to follow the anatomical evolution of the ossifications. It is perfectly suitable for the study of sacro-iliac and interapophyseal joints. Ossifying enthesites, the evolution of which spreads over several years, often depend on mechanical, professional or athletic constraints. Ossifying enthesitis is a common characteristics of ''classic'' spondylo-arthropathies which are all ossifying polyenthesites: ankylosing spondylarthritis, psoriasic rheumatism, rheumatism of enteropathies, Fiessinger-Leroy-Reiter syndrome and juvenile spondylo-arthropathies [fr

Adverse reaction to metal debris with concomitant incidental crystalline arthropathy in hip arthroplasty

Directory of Open Access Journals (Sweden)

2017-03-01

Full Text Available Adverse reaction to metal debris (ARMD is a known cause of failed metal in hip arthroplasty. Diagnosis of this type of prosthesis failure may be difficult, and the hallmark is an abnormally elevated serum cobalt level. Concomitant diagnoses may also be present, such as infection, instability, and loosening, and this may confuse interpretation of abnormal laboratories. We present here, for the first time, 2 patients with ARMD and crystalline arthropathy. In each case, the patient chose surgery for ARMD, with resolution of symptoms and no recurrence of the crystalline arthropathy. We present these cases to alert the orthopaedist that crystalline arthropathy may be present at the same time as ARMD, but is likely not the primary cause of symptoms.

An erosive arthropathy of the hands and wrists has been recognized in patients with primary and secondary hyperparathyroidism. Recently, intra-articular erosions of the humeral head were described in six patients who had been on chronic long-term hemodialysis with secondary hyperparathyroidism. We would like to present the finding of shoulder erosions in four patients with primary hyperparathyroidism and one patient with renal osteodystrophy and suggest that the humeral erosion can occur in both an intra-articular and peri-articular location.

Case report. We present a case of lumbar Charcot arthropathy successfully treated surgically using posterior 3-column resection, spinal shortening, and fusion. The operative treatment of Charcot arthropathy of the spine has conventionally been a combination of anterior and posterior surgery. The morbidity associated with these surgical procedures can be considerable. A posterior-only approach to the problem would avoid the additional morbidity associated with an anterior approach. We present a case of lumbar Charcot arthropathy with deformity treated successfully using such a procedure. Discussion of the patient's clinical and radiologic history, the technical merits of the operative intervention and a review of the relevant background literature are presented. A multilevel, single-stage, posterior 3-column resection with primary shortening and instrumented fusion augmented with rhBMP2 in a multiply operated patient with deformity provided a optimal biologic and mechanical environment for healing of the Charcot arthropathy and improved the sagittal and coronal profile of the spine. A single-stage, multilevel, posterior 3-column resection and primary shortening can be a useful surgical strategy in symptomatic patients with Charcot arthropathy of the spine.

Repetitive bleeding into the joint space is the cause of debilitative hemophilic arthropathy. To interrupt this process, we treated the hemophilic patients suffering from repetitive joint bleeding with radiation therapy. From 1997 to 2001, a total of 41 joints from 37 hemophilic arthropathy patients were treated with radiation therapy at KyungHee University Hospital. The treated joints were 35 ankles, 3 knees and 3 elbows, respectively. The age of the patients ranged from 4 to 27 years (median age: 11 years). The radiation dose ranged from 900 cGy to 2360 cGy (median dose: 900 cGy). The fraction size was 150 cGy, 180 cGy or 200 cGy. The number of bleeding in one year before and after radiotherapy was compared. There was a tendency of frequent bleeding for the patients younger than 11 ({rho} 0.051) but there was also a tendency for more improvement in this group ({rho} 0.057). The number of joint bleedings was related with joint pain ({rho} 0.012) and joint swelling ({rho} = 0.033) but not with the Arbold-Hilgartner stage ({rho} 0.739),cartilage destruction ({rho} = 0.718) and synovial hypertrophy ({rho} = 0.079). The number of bleeding was reduced in thirty-three cases, and eight cases showed no improvement after radiation therapy. The average number of bleeding in a month was 2.52 before radiotherapy, but this was reduced to 1.4 after radiotherapy ({rho} = 0.017). Radiation therapy was effective for the hemophilia patients with repetitive joint bleeding to decrease the bleeding frequency and to prevent hemophilic arthropathy.

The neuropathic arthropathy is an illness that destroys the articulation, associated to loss of the propiocepcion. Inside the main causes they are the syringomyelia, tertiary syphilis and diabetes mellitus. In the superior member the frequently affected articulation is the glen humeral. In this report two patients are presented with neuropathic arthropathy from the shoulder secondary to syringomyelia and remitted to orthopedic oncology with diagnosis of condrosarcoma. The clinical radiological presentation and the differential diagnosis are analyzed

Full Text Available ABSTRACT OBJECTIVE: To describe occurrences of septic glenohumeral arthritis among patients with arthropathy of the rotator cuff, and to highlight the importance of correct diagnosis and surgical procedures. METHODOLOGy: Eight surgical drains were installed in seven patients with glenohumeral pyoarthritis. All the patients presented arthropathy of the rotator cuff (four males and three females. Six patients presented pyoarthritis in the dominant shoulder. The age range was from 53 to 93 years (mean: 74 years. The mean duration of the symptoms before the surgical lavage was six weeks. Six patients underwent treatment consisting of a combination of arthroscopic irrigation and debridement, and one patient was treated by means of open arthrotomy. All the patients received systemic antibiotic therapy in accordance with their bacterial sensitivity. RESULTS: All seven patients achieved satisfactory results, taking into consideration especially the improvement of pain and the patients' satisfaction. The functional assessment was performed using the University of California Los Angeles (UCLA scale. Only one patient needed to go through another arthroscopic procedure. Staphylococcus aureus was isolated from four cultures and Escherichia coli from one culture. There were two situations in which the patients used empirical antibiotic therapy and the cultures showed negative results. Among the associated procedures, tenotomy of the biceps was performed in four cases, resection of the lateral third of the clavicle due to osteomyelitis in one case and arthrotomy of the knee in one case. CONCLUSION: Surgical treatment was effective in the cases of arthritis associated with arthropathy of the rotator cuff. In patients with arthropathy of the rotator cuff and subclinically altered laboratory signs, the possibility of pyoarthritis should always be suspected.

Radionuclide synovectomy – essentials for rheumatologists

Directory of Open Access Journals (Sweden)

Marek M. Chojnowski

2016-07-01

Full Text Available Radionuclide synovectomy is a minimally invasive method of treating persistent joint inflammation. It involves intra-articular injection of radioactive colloids which induce necrosis and fibrosis of hypertrophic synovial membrane. The most common indication for radiosynovectomy is rheumatoid arthritis, although patients with seronegative spondyloarthropathies, unclassified arthritis, haemophilic arthropathy and other less common arthropathies can also benefit from this method. Radiosynovectomy is safe, well tolerated and efficacious. About 70–80% of patients respond well to the therapy. However, the therapeutic effects are considerably worse in patients with co-existent osteoarthritis and advanced joint degeneration. Despite its advantages, radionuclide synovectomy is not performed as often as it could be, so greater knowledge and understanding of this method are needed. The authors present the most important facts about radiosynovectomy that may help rheumatologists in their daily clinical practice.

Full text of publication follows. Planar control scintigraphies have been used for the detection of any possible extra articular leakage after radio-synovectomy in patients with haemophilic arthropathy. In this study we aimed at assessing whether utilization of SPECT-CT for the same purpose can provide additional information. Patients who fulfilled the following prerequisites were included for radio synovectomy application: (1) more than four hemorrhagic episodes in six months, (2) at least a Stage II haemophilic arthropathy according to the classification of Arnold and Haltering, and (3) persistent synovitis. Six male patients (5 hemophilia A, 1 hemophilia B) who suffered from haemophilic arthropathy with a mean age of 10.5 (range between 8-15) were included in this study. We administered 148-185 MBq Yttrium 90 silicate (Y-90) to 5 knee joints, 74 MBq Rhenium 186 (Re-186) to 1 elbow joint and 74 MBq Re-186 to two ankle joints of these patients. The median number of bleedings into the target joints was 10.1 ± 1.4 in the six months prior to the procedure. All patients were admitted to the hospital and treated with factor replacement so as to raise the factor level of the patient to 80% the following morning and 50% for three days thereafter. The effusion in the joint was evacuated before the injection of the radiocolloid. Intra-articular injections in ankle and elbow joints were done under fluoroscopic guidance. The joint was moved rapidly a few times to distribute the radiocolloid, after which a plaster of paris cast was applied for 72 hours. One hour after the RS, planar images of the treated joints and the regional lymph nodes were obtained with gamma camera and SPECT-BT acquisitions were obtained from treated joints to confirm the appropriate distribution of the radionuclide in the joint. Distribution of the radionuclide in joint spaces was normal and we haven't encountered any extra articular leakage. In one patient there was loculation at activity in

Spies, S.; Green, D.; Rana, N.A.; Milgram, J.W.; Mintzer, R.

1978-01-01

Arthropathy was evaluated in six patients with severe hemophilia (factor VIII<1%) using the technique of blood pool scanning. Employing an in vivo method for erythrocyte labelling with technetium-99m, a dynamic perfusion sequence was obtained using a scintillation camera over the joint(s) to be examined. Subsequently, equilibrium blood pool images of the joints were obtained to determine regional blood volume. In young patients with repeated episodes of acute hemarthrosis, increased vascularity and increased blood pool in the affected joints were demonstrated. In older patients with fixed, contracted joints and degenerative arthropathy, vascularity and regional blood volume were not abnormal. Blood pool scanning is a safe, non-invasive technique that augments the clinical and radiographic examination of the joints. The method is helpful in distinguishing acute joint bleeding from chronic synovitis and arthritis, and may prove useful in selecting patients for synovectomy. (author)

Haemophilia and other bleeding disorders remain an enigma to the dentists world over. They not only challenge the skills of dental specialists but also raise the question of how these individuals should be managed emotionally as well as psychologically. The high incidence of dental problems in haemophiliacs is most likely caused by the fear and apprehension not only on the part of the patients but also dentists of inducing bleeding during treatment which can even be life threatening in certain cases. With proper care, diligence and meticulous treatment planning, there is no dental treatment that cannot be performed in such patients. Mild haemophiliacs can be easily managed and can effectively undergo even surgical endodontics without factor replacement therapies. However, severe haemophilia can pose significant health hazard and needs thorough preparation to meet any exigencies arising during the treatment. This case report describes how one such severely haemophilic patient with pain and swelling in the left submandibular region was managed with nonsurgical endodontic treatment in mandibular molar teeth and also discusses the importance of correct methods of diagnosis and various treatment considerations in such patients.

This paper reports on twenty children with hemophilia examined to determine if MR imaging could be used to assess hemophilic arthropathy. Twenty-eight joints were imaged (17 knees, 10 ankles, 1 elbow) with plain radiography, US, CT, and MR imaging. The results were compared with the surgical view and histologic study of the articular components when synovectomy was done. These results show the usefulness of MR imaging: fluid collections in the joint space were evaluated, and it was possible to distinguish blood from inflammatory fluid. Synovial hypertrophy was appreciated, and findings correlated well with histologic study. Anomalies of articular cartilage, joint-space narrowing, and bone lesions were demonstrated early, when plain radiography findings were still normal

The development of Charcot changes is known to be associated with a high rate of recurrent ulceration and amputation. Unfortunately, the effect of Charcot arthropathy on quality of life in diabetic patients has not been systematically studied because of a lack of a disease-specific instrument. The purpose of this study was to develop and test an instrument to evaluate the health-related quality of life of diabetic foot disease. Subjects diagnosed with Charcot arthropathy completed a patient self-administered questionnaire, and clinicians completed an accompanying observational survey. The patient self-administered questionnaire was organized into five general sections: demographics, general health, diabetes-related symptoms, comorbidities, and satisfaction. The scales measured the effect in six health domains: 1) general health, 2) care, 3) worry, 4) sleep, 5) emotion, and 6) physicality. The psychometric properties of the scales were evaluated and the summary scores for the Short-Form Health Survey (SF-36) were compared to published norms for other major medical illnesses. Of the 89 enrolled patients, 57 who completed the questionnaire on enrollment returned a second completed form at 3-month followup. Over the 3-month followup period most of the patients showed an improvement in the Eichenholtz staging. The internal consistency of most was moderate to high and, in general, the scale scores were stable over 3 months. However, several of the scales suffered from low-ceiling or high-floor effects. Patients with Charcot arthropathy had a much lower physical component score on enrollment than the reported norms for other disease conditions, including diabetes. Quality of life represents an important set of outcomes when evaluating the effectiveness of treatment for patients with Charcot arthropathy. This study represents an initial attempt to develop a standardized survey for use with this patient population. Further studies need to be done with larger groups of

Haemophilic arthropathy is the major cause of disability in patients with haemophilia and, despite prophylaxis with coagulation factor concentrates, some patients still develop articular complications. We evaluate the feasibility of a tissue engineering approach to improve current clinical strategies for cartilage regeneration in haemophiliacs by using autologous chondrocytes (haemophilic chondrocytes; HaeCs). Little is known about articular chondrocytes from haemophilic patients and no characterisation has as yet been performed. An investigation into whether blood exposure alters HaeCs should be interesting from the perspective of autologous implants. The typical morphology and expression of specific target genes and surface markers were therefore assessed by optical microscopy, reverse transcription plus the polymerase chain reaction (PCR), real-time PCR and flow-cytometry. We then considered chondrocyte behaviour on a bio-hybrid scaffold (based on polyvinyl alcohol/Wharton's jelly) as an in vitro model of articular cartilage prosthesis. Articular chondrocytes from non-haemophilic donors were used as controls. HaeC morphology and the resulting immunophenotype CD44(+)/CD49c(+)/CD49e(+)/CD151(+)/CD73(+)/CD49f(-)/CD26(-) resembled those of healthy donors. Moreover, HaeCs were active in the transcription of genes involved in the synthesis of the extracellular matrix proteins of the articular cartilage (ACAN, COL1A, COL2A, COL10A, COL9A, COMP, HAS1, SOX9), although the over-expression of COL1A1, COL10A1, COMP and HAS was observed. In parallel, the composite scaffold showed adequate mechanical and biological properties for cartilage tissue engineering, promoting chondrocyte proliferation. Our preliminary evidence contributes to the characterisation of HaeCs, highlighting the opportunity of using them for autologous cartilage implants in patients with haemophilia.

In summary, a case has been presented of a 31-year-old woman with a history of mild trauma at the age of 14 years and recurrent periods of pain in the hip becoming increasingly more severe. The radiological features were those of marked arthropathy of the affected hip with suggested features of ischemic necrosis. The patient was an example of hemophilia A which occurs rarely in females. The nature of the laboratory and clinical features of deficiency in hemophilia was considered and the clinical and radiological manifestations were described. The differential diagnosis was discussed. The radiological features in the background of the clinical information strongly suggest that the diagnosis of hemophilic arthropathy of the hip is justified. (orig./SHA).

A total of 17 patients with hemophilic arthropathy of the knee joint were studied with static and dynamic MRI before and after an IV bolus injection of Gadolinium-DTPA (Gd-DTPA; 0.1 mmol/kg body weight). The T1-weighted spin-echo (SE) and gradient-echo (fast-field echo [FFE]) sequences were applied. The FFE sequences of eight consecutive scans carried out over a time interval of 160 s were used in order to determine the time to signal intensity (SI) curves of the synovial proliferations surrounding soft tissue, bone marrow, and joint effusion. After the administration of a contrast agent, synovial proliferations exhibited an increase on FFE and SE images of 47.7% (SD {+-} 14.3%) and 37.4% (SD {+-} 11.2%), respectively, whereas muscle and fatty tissue, tendons, bone marrow, and joint effusion revealed only a minor increase in SI. The gradient of SI (ratio SI/time) of pannus was 39.6%/min (SD {+-} 7.7%/min) and differed significantly (P < 0.001) from that of bone marrow, fatty tissue, muscle tissue, tendons, and joint effusion (P < 0.05). In contrast to synovial proliferations in rheumatoid arthritis, no differentiation between various pannus vascularities based on the degree of enhancement was possible. The Gd-DTPA-enhanced MRI studies delineate and quantify the synovial proliferations in hemophilic arthropathy. Dynamic studies in hemophilic arthropathy do not provide qualitative assessment of the inflammatory process. (orig.)

The impact of HSV for inflammatory arthropathy patients.

LENUS (Irish Health Repository)

O'Connor, Mortimer B

2012-02-01

Herpes simplex virus type 1 (HSV-1), also known as herpes labialis, is the etiologic agent of vesicular lesions of the oral mucosa commonly referred to as "cold sores". HSV-1 can also cause clinical disease in a wide variety of other anatomic locations including the genitalia, liver, lung, eye, and central nervous system. These infections can be severe, particularly in the setting of immunosuppression, such as inflammatory arthropathy patients on Methotrexate ± biological therapies. Here, we highlight the importance of physician awareness of HSV due to its potential impact for rheumatology patients.

Fifteen patients with bilateral, symmetrical chronic pyrophosphate arthropathy of the knee were given intra-articular injections of yttrium-90 (5 mCi) plus steroid (triamcinolone hexacetonide, 20 mg) into one knee, and saline plus steroid into the other (control) knee. Allocation of the 90 Y injection was random and double blind. After 6 months there was significantly less pain, inactivity stiffness, joint-line tenderness, and effusion in the 90 Y-injected knees than in the controls (p 90 Y-injected and control knees in the changes in range of movement (p 90 Y may be of benefit in chronic pyrophosphate arthropathy, a disease for which there is no treatment. The predilection of this condition to affect the knees of the elderly makes such treatment highly suitable because the joint lends itself readily to injection and the procedure carries very few actual or potential risks in this age group.

Three cases in which arthropathy of hip occurred by irradiation therapy were reported. After receiving the depth dose of 500 to 600 rads at the inguinal region, a severe coxalgia occurred suddenly after a definite latent period. There were increases of sedimentation rate and ..gamma.. globulin. In roentgenogram, narrowing of articular space, bone atrophy, central dearticulation, and bone destruction and osteosclerosis occurred rapidly in order. As pathological findings, vascular occlusion, hemorrhage, hemolysis, osteonecrosis, abrasion of cartilage, fibrosis, and infectious cellular infiltration were observed. First, blood vessels were damaged by irradiation. Thereafter, circulatory insufficiency occurred in cotyloid cavity and femoral head, to which the influence of load was added. Thus, it is considered that the disease occurred. It seems that an articular cartilage is not always radioresistant. It is considered that the narrowing of articular space in roentgenogram is due to the degenerative necrosis of cartilage. Much attention should be paid to complications such as this disease etc. in radiation therapy.

The detrimental effects of iron on the joint: a comparison between haemochromatosis and haemophilia.

Joint damage due to (recurrent) joint bleeding in haemophilia causes major morbidity. Although the exact pathogenesis has not been fully elucidated, a central role for iron is hypothesised. Likewise, in hereditary haemochromatosis joint destruction is caused by iron overload. A comparison between these types of arthropathy could provide more insight in the influence of iron in inducing joint damage. A literature review was performed to compare both disorders with respect to their clinical and histological characteristics, and preclinical studies on the influence of iron on different joint components were reviewed. Similarities in the features of arthropathy in haemochromatosis and haemophilia are cartilage degeneration, subchondral bone changes with osteophyte and cyst formation, and osteoporosis. In both disorders synovial inflammation and proliferation are seen, although this is much more explicit in haemophilia. Other substantial differences are the age at onset, the occurrence of chondrocalcinosis radiographically and calcium pyrophosphate dihydrate deposition disease in haemochromatosis, and a rapid progression with joint deformity and neovascularisation in haemophilia. Preclinical studies demonstrate detrimental effects of iron to all components of the joint, resulting in synovial inflammation and hyperplasia, chondrocyte death, and impaired osteoblast function. These effects, particularly the synovial changes, are aggravated in the presence of a pro-inflammatory signal, which is prominent in haemophilic arthropathy and minimal in haemochromatosis. Additional research is needed to further specify the role of iron as a specific target in treating these types of arthropathy. Published by the BMJ Publishing Group Limited.

Splenic rupture and intracranial haemorrhage in a haemophilic neonate: Case report and literature review

Directory of Open Access Journals (Sweden)

Ibrahim Adamu

2012-01-01

Full Text Available Splenic rupture and intracranial haemorrhage are life-threatening conditions infrequently encountered in neonates without history of birth trauma. External manifestations of birth trauma; namely, capput succadeneum and cephalhematoma, when present raise suspicions for more serious intracranial or visceral damage. Rupture of normal spleen without an obvious source of trauma in haemophilic neonate is a rare event. The concurrence of both conditions and the unusual presentation make this case a rare one that is seldom encountered in the literature. Additionally, when splenic rupture occurs, the consensus is to employ all non-operative techniques aimed at salvaging the spleen, thus avoiding the immune-compromised state associated with splenectomy. However, in this case, we present a 3-day-old male with family history of haemophilia A, who was diagnosed with splenic rupture and bilateral subdural haematomas and underwent splenectomy, albeit with post-operative complications, in light of haemodynamic instability and high ongoing transfusion requirements.

Objectives: To evaluate deferiprone related knee arthropathy in patients with fi-thalassemia major undergoing chelation therapy with deferiprone (LI). Materials and Methods. This study included 40 patients with β- thalassemia major on deferiprone; their ages ranged from 8 to 18 years with a mean age of 12.6 ± 3 years. Forty age and sex matched patients on desferal served as controls. Patients were subjected to clinical knee joint examination using the modified hemophilia joint health score (JHS), bilateral knee joint X-ray and bilateral knee joint ultrasound. Twenty patients of the deferiprone group with positive knee joint ultrasound findings were subjected to knee MRI. Data collected included age, sex, transfusion index, chelation history (dose, duration, and adverse effects), history of splenectomy and symptoms of knee or other joints arthropathy. Weight, height, BMI and Tanner staging of the patients were recorded. Laboratory investigations included CBC, ALT, serum ferritin, viral hepatitis markers (B,C) and echocardiography. Results: Among deferiprone group; 25 patients (62.5%) had knee symptoms while; 93.3% of the asymptomatic patients had evidence of knee joint affection by JHS compared to 17 symptomatic patients (42.5%) among desferal group (ρ> 0.05). Among deferiprone group 7 patients (17.5%) had symptoms of other joints arthropathy. Knee symptoms were more prevalent with longer duration of deferiprone therapy (ρ<0.05), knee joint effusion in US (ρ< 0.05) and Higher platelet count (ρ<0.05), while in desferal group it was related to poor compliance (ρ< 0.01) and higher serum ferritin levels (ρ=<0.01). JHS ranged from 0-33 with 39 (97.5%) affected patients. JHS was positively correlated to age, weight, height, BMI, Tanner staging and platelet count (ρ<0.01), and negatively correlated to transfusion index (ρ<0.01) with no significant correlation to ultrasound or MRI findings. JHS was higher among splenectomized patients in both groups (ρ<0.01). No

Full Text Available The development of arthropathy is a major co-morbidity in patients with hemophilia. The present study was designed to study the role of a microRNA biomarker (miR-15b in the development of joint disease. To investigate the expression profile of miR-15b during the development of arthropathy, we first isolated and studied small RNA from the acute and chronic hemarthrosis model of hemophilia A mice. We observed that miR-15b was consistently repressed (~1- to 4-fold from the onset of joint bleeding (1, 3, 7 and 24 h until six bleeding episodes (up to 90 days. To test if reconstitution of miR-15b modulates biomarkers of joint damage in a chronic hemarthrosis model, we administered an adeno-associated virus (AAV 5-miR-15b vector intra-articularly alone or in combination with systemic administration of AAV2-factor VIII. miR-15b overexpression downregulated markers of angiogenesis and hypoxia (vascular epithelial growth factor α (VEGF-α and hypoxia inducing factor 2α (HIF-2α, ~70% and ~34%, respectively in the affected joints. In addition, the co-administration of miR-15b and factor VIII vectors reduced the levels of the chondrodegenerative matrix-metalloproteinases (MMPs 1, 3, 9 and 14 (~14% to 60% in the injured joints. These data demonstrate for the first time the role of a miR-15b in the development of hemophilic arthropathy and has implications in development of miR based therapies for joint disease.

To evaluate the characteristic MR findings of hemophilic arthropathy of the knee. Seven keens in six patients with hemophilia (five hemophilia A and one hemophilia B) were retrospectively studied with MR images and plain radiographs. Patients were aged between 2 and 20 years (mean, 11) and all had a clinical history of repeated hemarthrosis. MR images of the knee were analyzed with respect to intra- and extra-articular hemorrhage, the state of synovial tissue, articular cartilage, bone, menisci, and ligaments. Synovial hypertrophy and articular cartilage destruction were revealed in all seven knees ; pannus was found in four, and was seen as low signal intensity on T1-weighted image and high signal intensity on T2-weighted images. All five instances of synovial hypertrophy and pannus were enhanced. Joint effusion, presented in five of seven knees, demonstrated slightly low signal intensity on T1-weighted image and high signal intensity on T2-weighted images, and was associated with peripheral low signal intensity of hemosiderin. Subchondral and marginal erosion was seen in six cases, patellar deformity in three, meniscal damage in four and cruciate ligament damage in one case. MR is superior to radiography in demonstrating chronic repeated hemarthrosis (manifested as thick intra-articular effusion), hemosidering, synovial hypertrophy, erosion or destruction of articular cartilage and bone, and meniscal or cruciate ligament injury of hemophilic arthropathy of the knee. MR is therefore thought to be a useful imaging study for accurate evaluation of hemophilic arthropathy of the knee

Pain, commonly localized to the trunk in individuals with COPD, may be due to osteoporosis-related vertebral deformity and chest wall hyper-expansion causing misalignment of joints between the ribs and vertebrae. The purpose of this study was to determine if thoracic vertebral deformity and arthropathy were independent contributors to trunk pain in COPD patients compared to people with a significant smoking history. Participants completed the Brief Pain Inventory (BPI) on the same day as chest CT scans and spirometry. Current and ex-smokers were separated into COPD (n = 91) or non-COPD (n = 80) groups based on spirometry. Subsequently, CT images were assessed for thoracic vertebral deformity, bone attenuation values, and arthropathy of thoracic vertebral joints. The trunk area was the most common pain location in both COPD and non-COPD groups. Thoracic vertebral deformity and costotransverse joint arthropathy were independent contributors to trunk pain in COPD patients (adjusted OR = 3.55 and 1.30, respectively) whereas alcohol consumption contributed to trunk pain in the non-COPD group (adjusted OR = 0.35 in occasional alcohol drinkers; 0.08 in non-alcohol drinkers). The spinal deformity index and the number of narrowed disc spaces were significantly positively related to the BPI intensity, interference, and total scores significantly in COPD patients. Trunk pain, at least in part, is caused by thoracic vertebral deformity, and costotransverse and intervertebral arthropathy in patients living with COPD. The results of this study provided the foundation for the management of pain, which requires further exploration. Copyright © 2018 Elsevier Ltd. All rights reserved.

The arthropathies of juvenile arthritis and hemophilia have in common abnormal hyperplastic synovium leading to marginal bone erosion, articular cartilage destruction, subchondral bone exposure, and dissolution and ultimately collapse of the affected joint. The authors examined children and young adults with juvenile arthritis and hemophilia by MR imaging and found that they could identify hyperplastic synovium, articular cartilage lesions, bone erosions, and joint effusions. This has therapeutic implications since identification of progressive synovial hyperplasia and/or early cartilage or marginal bone erosion may lead to earlier synovectomy in patients with hemophilia or switch to second line drugs in patients with juvenile arthritis, in an attempt to prevent progressive joint destruction

Full Text Available Abstract Background This study evaluates the preoperative conventional anteroposterior radiography and clinical testing in non-operated patients with cuff tear arthropathy. It analyses the radiological findings in relation to the status of the rotator cuff and clinical status as also the clinical testing in relation to the rotator cuff quality. The aim of the study is to define the usefulness of radiography and clinical examination in cuff tear arthropathy. Methods This study analyses the preoperative radiological (AP-view, (Artro-CT-scan or MRI-scan and clinical characteristics (Constant-Murley-score plus active and passive mobility testing and the peroperative findings in a cohort of 307 patients. These patients were part of a multicenter, retrospective, consecutive study of the French Orthopaedic Society (SOFCOT-2006. All patients had no surgical antecedents and were all treated with prosthetic shoulder surgery for a painful irreparable cuff tear arthropathy (reverse-(84% or hemi-(8% or double cup-bipolar prosthesis (8%. Results A positive significancy could be found for the relationship between clinical testing and the rotator cuff quality; between acromiohumeral distance and posterior rotator cuff quality; between femoralization and posterior rotator cuff quality. Conclusion A conventional antero-posterior radiograph can not provide any predictive information on the clinical status of the patient. The subscapular muscle can be well tested by the press belly test and the teres minor muscle can be well tested by the hornblower' sign and by the exorotation lag signs. The upward migration index and the presence of femoralization are good indicators for the evaluation of the posterior rotator cuff. An inferior coracoid tip positioning suggests rotator cuff disease.

Full Text Available Alkaptonuria is a rare, autosomal recessive disorder of phenylalanin/tyrosine metabolism due to congenital deficiency of the enzyme homogentisic acid oxidase. The diagnosis is clinical and the triad of homogentisic aciduria, ochronosis and precocious degenerative arthritis is characteristic. Its diagnosis in infancy and early therapeutic intervention help delaying its complications. These patients may remain undiagnosed until the darkening of urine soaked diapers is noticed or the early degenerative arthropathy develops. This paper describes two cases of alkaptonuria presenting late in life; one of them had associated hyperthyroidism.

Case report 471: Hemophilic pseudotumors (presumptive diagnosis) and hemophilic arthropathy of elbow

1988-03-01

A case has been presented of a 72-year-old man on whom an excretory urogram showed the incidental findings of two soft tissue masses in the abdomen containing considerable deposits of calcium. The history was interesting in that the patient was classic hemophiliac with Factor VIII level less than 1%, who first developed symptoms and signs of multiple hemarthroses affecting the knees, ankles, elbows, and shoulders at the age of nine years. Secondary hemophilic arthropathy followed, particularly advanced in the right elbow. Total knee replacements were performed within the last 10 years. A mass within the muscles of the right chest wall, superficial to the ribs, was surgically removed. The abdominal masses in this case were studied with CT and showed considerable calcification with a fibrous wall. Surgical removal of pseudotumors is usually undertaken following diagnosis because the natural history includes continuous enlargement and destruction of the adjacent tissues. Because of the age of the patient and the significant cardiac history, it was considered inappropriate to undertake surgery for the masses in the abdomen which were considered presumptively to be pseudotumors. The clinical, radiological, and pathological aspects of pseudotumor of hemophilia were reviewed. In this case, besides the masses in the abdomen, hemophilic arthropathy of an elbow was illustrated and a soft tissue mass in the right chest wall was demonstrated radiologically and the pathological specimen shown after surgical excision.

Low CD4/CD8 T-cell ratio associated with inflammatory arthropathy in human T-cell leukemia virus type I Tax transgenic mice.

Takeo Ohsugi

Full Text Available BACKGROUND: Human T-cell leukemia virus type I (HTLV-1 can cause an aggressive malignancy known as adult T-cell leukemia/lymphoma (ATL as well as inflammatory diseases such as HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP. A transgenic mouse that expresses HTLV-1 Tax also develops T-cell leukemia/lymphoma and an inflammatory arthropathy that resembles rheumatoid arthritis. The aim of this study was to identify the primary T-cell subsets involved in the development of arthropathy in Tax transgenic mice. PRINCIPAL FINDINGS: By 24 months of age, Tax transgenic mice developed severe arthropathy with a cumulative incidence of 22.8%. The pathological findings of arthropathy in Tax transgenic mice were similar to those seen in human rheumatoid arthritis or mouse models of rheumatoid arthritis, with synovial proliferation and a positive rheumatoid factor. Before the onset of spontaneous arthropathy, young and old Tax transgenic mice were not sensitive to collagen and did not develop arthritis after immunization with type II collagen. The arthropathic Tax transgenic mice showed a significantly decreased proportion of splenic CD4(+ T cells, whereas the proportion of splenic CD8(+ T cells was increased. Regulatory T cells (CD4(+CD25(+Foxp3(+ were significantly decreased and CD8(+ T cells that expressed the chemokine receptor CCR4 (CD8(+CCR4(+ were significantly increased in arthropathic Tax transgenic mice. The expression of tax mRNA was strong in the spleen and joints of arthropathic mice, with a 40-fold increase compared with healthy transgenic mice. CONCLUSIONS: Our findings reveal that Tax transgenic mice develop rheumatoid-like arthritis with proliferating synovial cells in the joints; however, the proportion of different splenic T-cell subsets in these mice was completely different from other commonly used animal models of rheumatoid arthritis. The crucial T-cell subsets in arthropathic Tax transgenic mice appear to resemble

Premature arterial stiffening and atherosclerosis are increased in patients with inflammatory arthropathies such as rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA). The proinflammatory protein calprotectin is associated with inflammatory arthropathies, vascular pathology, and acute coronary events. We examined the long-term effects of treatment with tumor necrosis factor (TNF)-α antagonists on aortic stiffness and carotid intima media thickness (CIMT) in patients with inflammatory arthropathies, and the relationships to the levels of calprotectin. Fifty-five patients with RA, AS, or PsA and a clinical indication for anti-TNF-α therapy were included and followed with regular examinations for 1 year. Thirty-six patients starting with anti-TNF-α therapy were compared with a nontreatment group of 19 patients. Examinations included assessments of aortic stiffness (aortic pulse wave velocity, aPWV), CIMT, and plasma calprotectin. After 1 year, aPWV (mean (s.d.)) was improved in the treatment group, but not in the control group (-0.54 [0.79] m/s vs. 0.06 [0.61] m/s, respectively; P = 0.004), and CIMT progression (median (quartile cut-points, 25th and 75th percentiles)) was reduced in the treatment group compared to the control group (-0.002 [-0.038, 0.030] mm vs. 0.030 [0.011, 0.043] mm, respectively; P = 0.01). In multivariable analyses, anti-TNF-α therapy over time was associated with improved aPWV (P = 0.02) and reduced CIMT progression (P = 0.04), and calprotectin was longitudinally associated with aPWV (P = 0.02). Long-term anti-TNF-α therapy improved aortic stiffness and CIMT progression in patients with inflammatory arthropathies. Calprotectin may be a soluble biomarker reflecting aortic stiffening in these patients.

Reverse total shoulder arthroplasty in rotator cuff arthropathy patients, improves anteversion and abduction, but not rotational, outcomes. The main aim of this study is to determine its repercussions on daily life activities in our patients. Between 2009 and 2011 we implanted 210 shoulder arthroplasties, 126 of them were reverse total shoulder arthroplasty in a rotator cuff arthropathy context. About 88% were women, with a mean age at time of surgery of 81 years, 95% were retired. The mean follow up was 53 months. The Constant scale, Visual Analogue Scale, Charlson Comorbidity Index, range of motion were measured for each patient and whether they could manage 40 daily life activities by means of a new questionnaire, classifying them according toshoulder functional demand. Mean normalized by sex and age Constant value was 81.2%. Mean Visual Analogue Scale and Charlson Index were 3.56 and 1.69 respectively. Improvement in anteversion and abduction, not in rotational range of motion. Limitation was found in low and high functional demand activities in 20% and 51% respectively, especially those which involved internal rotation. Reverse total shoulder arthroplasty treatment for RCA in the elderly, achieves adequate pain management and good functional outcomes. Nevertheless, an important risk of DLA limitation must be accepted in those which involve internal rotation or shoulder high functional demand. Copyright © 2017 SECOT.

The 99m Tc hydroxy methylene diphosphonate scintigraphic findings of both hands are correlated to the radiographic findings in a patient with a 30-year history of gouty arthropathy. Scintigraphic differentiation of the type of arthritis on the basis of uptake pattern is difficult. However, the findings of rheumatoid arthritis are confined to the joints and usually the involvement is symmetrical. With gout there is a tendency toward asymmetrical, bilateral, multifocal joint involvement with areas of intense abnormal uptake; because of the associated soft tissue swelling, the intense uptake usually extends beyond the involved joints.

Ochronotic Arthropathy: Two Case Reports from a Developing Country

Directory of Open Access Journals (Sweden)

Farooq A. Rathore

2016-01-01

Full Text Available Alkaptonuria is a rare inborn error of metabolism, which is classified as an orphan disease. It is due to the lack of an enzyme homogentisate 1,2-dioxygenase, which results in an accumulation of homogentisic acid in different areas of the body, including sclera, skin, cardiac valves, articular cartilage of the large joints and intervertebral disks. We present two cases of alkaptonuria resulting in ochronotic arthropathy with advanced secondary generalized osteoarthritis, intervertebral disk calcifications, skin and scleral pigmentation. In these case reports, both patients had symptoms for >10 years before being diagnosed. Conservative management in the form of high-dose ascorbic acid, exercises, and gait aids was offered to both of them, which resulted in some symptomatic improvement in the first case, while the second case was lost to follow-up. Alkaptonuria is a rare disease, and although it does not clearly impact mortality, early diagnosis may improve the quality of life.

Full Text Available Objective: We aimed to assess the role of Magnetic Resonance Imaging (MRI and X-Ray in the evaluation of response to radiosynovectomy (RS in patients with hemophilic arthropathy. Material and Methods: Eleven patients who suffered from hemophilic arthropathy with a mean age of 11.7 (range between 7-15 were included in this study. 148-185 MBq Yttrium 90 silicate (Y-90 was administered intraarticularly to ten knee joints and one patient was treated with intraarticular 74 MBq Rhenium 186 (Re-186 injection into his ankle. Before radiosynovectomy, plain anteroposterior and lateral X-rays of the target joints were obtained by standard technique. The follow-up MRI and X-ray studies of the patients were done 6 months after RS. Pettersson hemophilic arthropathy scales were utilized to stage the condition of the joints on plain X-ray and classification of the investigated joints on MRI were done according to Denver score. The clinical assessment of the efficacy of the RS was made with the comparison of the average bleedings before and after the intervention. Results: During the 6-month follow-up period after RS, an improvement in number of hemarthrosis 75% or greater compared with the prior six months occurred in six joints (54.5%. The Pettersson scores worsened in 1/11 (9%, remained unchanged in 9/11 (81.8%, and improved in 1/11 (9% joints. At the 6-month follow-up, the MRI score worsened in one (9% and was unchanged in 10/11 joints (90.9%. Conclusion: MRI is a more sensitive tool than plain radiography for evaluating and follow-up of joint disease in persons with hemophilia, but both methods don’t show correlation with the therapeutic response.

Increased articular {sup 99m}Tc MDP uptake on blood pool imaging (BPI) of patients with rheumatologic conditions is indicative of active inflammatory changes, and has been suggested as a strong predictor of response to radiosynoviorthesis (RSO). In this study, we aimed to assess the value of pretreatment BPI positivity (i.e. scintigraphic-apparent hyperemia) for successful RSO in hemophilic arthropathy. Thirty-four male patients with painful hemophilic arthropathy underwent RSO after failure of conservative treatment. Treated joints comprised the knee in eight, elbow in five, and ankle in 21 patients. Pretreatment triple-phase bone scintigraphy showed hyperemic joints (pathologic BPI) in 17 patients, whereas 17 patients had no increased tracer uptake on BPI. Response to RSO was evaluated 6 months post-treatment by measuring changes in intensity of arthralgia according to the visual analog scale (VAS), bleeding frequency, and range of motion. The association between hyperemia (pathologic BPI) and treatment outcome was examined using nonparametric tests for independent samples. Clinically evident pain relief occurred in 26 patients (76.5 %), and the mean VAS decreased from 7.7 ± 1.1 to 4.6 ± 2.7 (p < 0.001). Joint bleeding frequency (hemarthrosis) decreased from 4.5 ± 0.6 to 2.1 ± 0.4 during the first 6 months after RSO (p < 0.001). For both parameters (pain relief and bleeding frequency), patients experienced a similar benefit from RSO regardless of pretreatment BPI: arthralgia (p = 0.312) and frequency of hemarthrosis (p = 0.396). No significant improvement was observed for range of motion, but it was significantly more restricted in hyperemic joints both before (p = 0.036) and after treatment (p = 0.022). Hemophilic arthropathy can be effectively treated with RSO regardless of pre-therapeutic BPI. Patients in whom articular hyperemia is not detectable by scintigraphy may have similar (outstanding) outcomes, and thus should not be excluded from treatment. (orig.)

In a series of 28 long-term dialysis patients with musculoskeletal complaints, the radiologic findings in six cases resembled those occurring in the arthropathy of idiopathic calcium pyrophosphate dihydrate deposition (CPPD) disease. These findings included osteophytes, subchondral cysts, and cartilage loss in the metacarpophalangeal joints, patellofemoral joints, wrists, and shoulders. Chondrocalcinosis was present in three of the six cases. There were no significant differences in renal function or levels of serum calcium, phosphorus, iron, ferritin, aluminum, or parathormone between these patients and a control group matched for sex and age. Long-term dialysis may be associated with a metabolic arthritis similar to the arthritis which occurs in CPPD deposition disease. The etiology may include deposition of CPPD crystals, hydroxyapatite, or other calcium-containing substances in joints, or it may be related to a number of dialysis-induced metabolic abnormalities.

To define the molecular basis of a multisystem phenotype with progressive musculoskeletal disease of the hands and feet, including camptodactyly, subluxation, and tendon rupture, reminiscent of Jaccoud's arthropathy. We identified 2 families segregating an autosomal-dominant phenotype encompassing musculoskeletal disease and variable additional features, including psoriasis, dental abnormalities, cardiac valve involvement, glaucoma, and basal ganglia calcification. We measured the expression of interferon (IFN)-stimulated genes in the peripheral blood and skin, and undertook targeted Sanger sequencing of the IFIH1 gene encoding the cytosolic double-stranded RNA (dsRNA) sensor melanoma differentiation-associated protein 5 (MDA-5). We also assessed the functional consequences of IFIH1 gene variants using an in vitro IFNβ reporter assay in HEK 293T cells. We recorded an up-regulation of type I IFN-induced gene transcripts in all 5 patients tested and identified a heterozygous gain-of-function mutation in IFIH1 in each family, resulting in different substitutions of the threonine residue at position 331 of MDA-5. Both of these variants were associated with increased IFNβ expression in the absence of exogenous dsRNA ligand, consistent with constitutive activation of MDA-5. These cases highlight the significant musculoskeletal involvement that can be associated with mutations in MDA-5, and emphasize the value of testing for up-regulation of IFN signaling as a marker of the underlying molecular lesion. Our data indicate that both Singleton-Merten syndrome and neuroinflammation described in the context of MDA-5 gain-of-function constitute part of the same type I interferonopathy disease spectrum, and provide possible novel insight into the pathology of Jaccoud's arthropathy. © 2017, American College of Rheumatology.

Objective: To compare MR, CT, and radiography in the detection of arthropathies in patients with hemophilia. Methods: Forty-one symptomic joint images in the 14 patients with hemophilia, aged from 11 to 24 years, were used in this study. Each joint had the examinations of radiography, CT and MR within one day. The severity of each joint was staged using conventional radiographic classification. Severe HA patients with stage 5 were excluded from the study. Imaging findings of soft tissue swelling, osteoporosis, epiphyseal overgrowth, joint erosion, cyst, joint space narrowing, bone marrow, joint effusion, hemorrhage, synovial hypertrophy, widened intercondylar notch as well as anterior and posterior cruciate ligaments (only for knee joint) were used for the all imaging comparison. Results: The 41 symptomatic joints in 14 patients with hemophilia were classified by radiographic criteria into stage 0 (n=5), stage 1 (n=7), stage 2 (n=6), stage 3 (n=8) and stage 4 (n=15). Soft tissue swelling or joint effusion was observed in 33 joints by radiographs, in 34 joints by both CT and MR. Joint erosions were demonstrated in 34 joints by MR, in 33 joints by CT and 20 joints by radiographs. Joint cysts were shown in 21 joints by MR, in 18 joints by CT and 9 joints by radiographs. Significant differences in detection of erosion and cyst were found between radiography with either CT (P 0.05). MR showed improvement for detecting more foci of both erosion and cyst than CT and radiography, and also CT showed the improvement than radiography. Bone marrow edema 14 joints, hemorrhage in 34 joints and synovial hypertrophy in 27 joints were revealed on MR images. Conclusion: MRI is superior to CT and conventional radiography in detecting the abnormal changes and should be considered as the first choice among the imaging modalities in evaluating hemophilic arthropathies.

Objective: To study the MRI features and the cartilaginous pathology of the spondyloepiphyseal dysplasia tarda with progressive arthropathy (SEDT-PA). Methods: MRI of spine, bilateral hips, and knees was taken in 2 cases with clinically and radiographically proven SEDT-PA, who were sister and brother and whose parents were healthy and not inbreeding. The sister's femoral heads were resected bilaterally and the tissues were used for pathological study. Results: MRI showed that the kyphosis and lateroflexion of the spine, and the degenerative signs of the intervertebral discs became more evident along with the growth of the patients. The anterior annular secondary ossification centers of cartilaginous epiphyses of some vertebral bodies didn't appear. So the affected vertebral bodies were like 'inverted vase' or the end p late like 'steps'. Bilateral acetabular cartilage and medial epicondylian cartilaginous epiphyses of the femurs in the young brother showed regional high signal intensity on coronal fat-saturated proton density weighted MR images and degenerative signs on the elder sister. The regional hyperplasia and hypogenesis of the femoral head cartilage could be seen by microscope. Conclusion: There are characteristic features on MRI in SEDT-PA and this is due to the regional hyperplasia and hypogenesis of the cartilage pathologically. (authors)

Radiocolloids in the management of hemophilic arthropathy in children and adolescents

Erken, E.H.

Radiocolloids have been used in the treatment of hemophilic arthropathy. Fifty-eight joints of 35 patients were injected with 2-5 mCi of yttrium-90 silicate under local anesthesia. A preinjection arthrogram was performed to ensure correct placement of the needle. Plaster of paris cast immobilization of the joint was used for three days. After a mean follow-up period of seven years (range, two to 12 years), 47 joints were pain free, and 13 joints had not experienced another hemorrhagic episode. The mean hemorrhagic frequency had decreased from four per month to two per year. The radiation risk was far outweighed by the benefits of the procedure. Forty-seven of the 58 joints were rated as improved by the patients. The roentgenographic appearance of the joints had changed little. Only five complications occurred: three needle-track necroses because of extravasation of the radiocolloid, two severely painful joints immediately after injection, and one massive hemorrhagic episode. This form of treatment is suggested for hemophiliacs who have failed to respond to intensive physical and hematologic therapy, and for those patients who have inhibitors

Objective: To assess the feasibility of HEAD-US scale in the clinical application of hemophilic arthropathy (HA) and propose an optimized ultrasound scoring system. Methods: From July 2015 to August 2017, 1 035 joints ultrasonographic examinations were performed in 91 patients. Melchiorre, HEAD-US (Hemophilic Early Arthropathy Detection with UltraSound) and HEAD-US-C (HEAD-US in China) scale scores were used respectively to analyze the results. The correlations between three ultrasound scales and Hemophilia Joint Health Scores (HJHS) were evaluated. The sensitivity differences of the above Ultrasonic scoring systems in evaluation of HA were compared. Results: All the 91 patients were male, with median age of 16 (4-55) years old, including 86 cases of hemophilia A and 5 cases hemophilia B. The median ( P 25 , P 75 ) of Melchiorre, HEAD-US and HEAD-US-C scores of 1 035 joints were 2(0,6), 1(0,5) and 2(0,6), respectively, and the correlation coefficients compared with HJHS was 0.747, 0.762 and 0.765 respectively, with statistical significance ( P cases of asymptomatic joints, the positive rates of Melchiorre, HEAD-US-C and HEAD-US scale score were 25.0% (95% CI 20.6%-29.6%), 17.0% (95% CI 12.6%-21.1%) and 11.9% (95% CI 8.4%-15.7%) respectively, and the difference was statistically significant ( P joints of 40 patients. The difference in variation amplitude of HEAD-US-C scores and HEAD-US scores before and after joint bleeding was statistically significant ( P <0.001). Conclusion: Compared with Melchiorre, there were similar good correlations between HEAD-US, HEAD-US-C and HJHS. HEAD-US ultrasound scoring system is quick, convenient and simple to use. The optimized HEAD-US-C scale score is more sensitive than HEAD-US, especially for patients with HA who have subclinical state, which make up for insufficiency of sensitivity in HEAD-US scoring system.

Anti-Tumor Necrosis Factor (TNF)-α therapy improves vascular pathology in inflammatory arthropathies such as rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis. The l-arginine/ADMA ratio is important for modulation of the nitric oxide synthase activity. We examined the effect of TNF-α antagonists on ADMA and l-arginine/ADMA, and associations between ADMA, L-arginine/ADMA, aortic stiffness and carotid intima media thickness (CIMT) in patients with inflammatory arthropathies. Forty-eight patients who started with anti-TNF-α therapy were compared with a non-treated group of 32 patients. Plasma ADMA and L-arginine were assessed at baseline, 3 and 12 months. In a subgroup of 55 patients, aortic pulse wave velocity (aPWV) was measured at baseline, 3 and 12 moths, and CIMT was examined at baseline and 12 months. Anti-TNF-α therapy increased the L-arginine/ADMA ratio (mean [SD]) in the treatment group compared to the control group after 3 months (12 [29] vs. -13 [20], P < 0.001) and 12 months (7 [27] vs. -8 [19], P = 0.008), but did not affect ADMA (3 months: 0.00 [0.09] μmol/L vs. 0.02 [0.07] μmol/L, P = 0.42, 12 months: 0.01 [0.08] μmol/L vs. 0.01 [0.09] μmol/L, P = 0.88). Baseline aPWV was associated with ADMA (P = 0.02) and L-arginine/ADMA (P = 0.02) in multiple regression analyses, and the L-arginine/ADMA ratio was continuously associated with aPWV after initiation of anti-TNF-α therapy (P = 0.03). ADMA and L-arginine/ADMA were not correlated with CIMT. Anti-TNF-α therapy improved the L-arginine/ADMA ratio in patients with inflammatory arthropathies. ADMA and the L-arginine/ADMA ratio were associated with aPWV, and might have a mechanistic role in the aortic stiffening observed in these patients. Copyright © 2012 Elsevier Ireland Ltd.

Full Text Available Military personnel are often subjected to physical exertion, sleep deprivation, deficient diets, overcrowding, and stress. All of these influences are capable of compromising the immune system’s ability to ward off disease-causing bacteria, thus explaining why the historical narrative of war is frequently accompanied by reports of death and suffering due to epidemics of infectious diseases. Historically some of the most common infections included: diarrhoea, dysentery, typhoid fever, gonorrhoea, and streptococcal tonsillitis. The bacteria which cause these diseases are also capable of triggering arthritis. When an arthritic condition is triggered by an infectious microbe it can broadly be referred to as “reactive arthropathy,” of which the spondyloarthritides (SpAs are of great interest. Since the bacteria associated with these arthritic conditions are responsible for the epidemics which have plagued combatants for centuries, it is reasonable to assume that reactive arthropathy was present in past military populations. This assertion can be tested through a prevalence study of military related skeletal assemblages. To test the methodology and gain preliminary results for this research project, a pilot study was carried out using remains from the 1461 Battle of Towton. The methodology was deemed to be sound and the statistical results, while not significant, were promising.

The aim of this study was to assess the distribution of bone erosions in the feet of patients with gout using CT and thereby to test the hypothesis that gout is an asymmetric arthropathy. CT scans of both feet were obtained from 25 patients with chronic gout. CT scans were scored for bone erosion using a semi-quantitative method based on the rheumatoid arthritis MRI scoring system (RAMRIS). CT bone erosion was assessed at 22 bones in each foot (total 1,100 bones) by two independent radiologists. Symmetry was assessed by two methods: (i) comparing right and left foot scores for each patient; and (ii) calculating the proportion of paired joints with or without erosions. Observer agreement was excellent (intra-class correlation coefficient 0.92). In the group overall, the difference in scores between the feet was not significant (Student's t-test P = 0.8). In 17 of 25 patients, the difference in erosion scores between the two feet was less than the inter-observer difference. In 24 of 25 patients, the proportion of paired joints was greater than 0.5, indicating symmetric disease. Erosive disease from gout is, in fact, a symmetric process in our patient group. This finding is contrary to the established view of gout as an asymmetric arthritis and lends new insight into the behaviour of this common disease.

Joint lavage followed by intra-articular injection of hyaluronic acid and/or corticosteroids in patients with severe hemophilic arthropathy of the knee: Is this intervention really effective?

The aim of this review is to explore the scientific rationale and evidence for a potential benefit of joint lavage followed by intra-articular injection of hyaluronic acid and/or corticosteroids in patients with severe hemophilic arthropathy of the knee (SHAK). Areas covered: This article is a narrative review of the evidence for potential benefits of joint lavage followed by intra-articular injection of hyaluronic acid and corticosteroids in SHAK compared with osteoarthritis of the knee in non-hemophilia patients. Expert commentary: Although some reports on hemophilic arthropathy with a low-grade of evidence seem to indicate a benefit of joint lavage followed by intra-articular injection of hyaluronic acid and/or corticosteroids in patients with SHAK, the short-lived improvements afforded by hyaluronic acid, and the doubtful benefits of corticosteroids and joint lavage in hemophilia, do not warrant their use in hemophilic patients. The scientific rationale of these procedures is poor and they are not recommended.

Introduction - We preconized the use of 153 Sm-Hydroxyapatite (HYP) in the synoviorthesis of haemophilic patients (pts) by physical, chemical and biological characteristics. The real efficacy is being confirmed by the actual experience over the previous results. These are the first results with 153 Sm-HYP in our literature review. Material and Methods - Fifteen pts. were treated, all males, with ages between 15 and 31 years (average = 22,8 years old), with an intraarticular injection of 185 MBq (5mCi) of 153 Sm-HYP, totalizing 29 joints: 12 knees, 11 elbows, 4 ankles and 2 shoulders. The 153 Sm, produced by IPEN/CNEN - Sao Paulo, targeted hydroxyapatite particles with a diameter between 1-10μm, radiochemical purity superior to 95% and stability of 96,6% 1440min after the labeling process. The intraarticular punction was made after local antiseptic, aspirating synovial fluid, injecting 0,5 ml of radioactive solution and flushing the tract with a saline with a total volume no greater than 1,5 ml. The images were obtained 2 and 24h after injection in all pts in a large field of view gamma-camera. The clinical evaluation was made before and one year after it, using objective (range of motion, joint tenderness, degree of joint effusion) and subjective criteria (joint pain by visual scale and joint aspect). The response were graded: 1 - Excellent (E); 2 - Good (G); 3 - Mild (M); 4 - Bad (B); 5 - Worse (W). The reduction in clotting factor use and heamarthroses were others aspects evaluated. Results - The scintigrafies showed homogeneous distribution of the material in joints (2h) and no articular scape (24h). The was a reduction of 34% in the clotting factor use and of 51,4% in haemarthroses including the poor responses in knees. The results by patients were: 53,3% E, 20% G, 13,3% M, 13,3% B, 0% W and by joints were 47,75 with excellent and good responses and 84,75% when included the mild group. There was no patient without response. Few patients (4) had local pain in

Chronic arthritis is very common and is associated with a variety of systemic diseases whereas hemophilic arthropathy is one of the most common clinical manifestations of hemophilia, mainly of hemophilia type A. All of these polyarticular diseases are associated with progressive pain and increasing lack of mobility. Therapy is based on conservative treatment such as medication with non-steroidal anti-inflammatory drugs, selective therapy strategies such as intraarticular injections of e.g. radioactive substances (radiosynoviorthesis) or surgical interventions. However, in some cases, the disease does not respond to one of these treatment options or cannot be continued due to important side-effects. Systemic application of radioisotopes like 186 Re HEDP has been successfully administered for pain palliation of osseous metastases. Today, only few data exist for systemic therapy with 186 Re HEDP in patients suffering from benign polyarticular disease. In a prospective study with patients suffering from chronic arthritis a single systemic application of 186 Re HEDP led to a reduction of disease activity in six of eight and to a reduction of the number of painful or swollen joints in five of eight included patients. In a further prospective study with 12 patients with hemophilic arthropathy, 19 of 36 (52.7%) most painful joints could be successfully treated with one systemic 186 Re HEDP therapy. Furthermore, a reduction of global pain could be observed in those patients. However, further randomized studies with larger study populations are necessary in order to confirm this promising results. (orig.)

The aim of this study was to evaluate the clinical and radiological outcome of the Total Evolutive Shoulder System (TESS) in patients with cuff tear arthropathy and patients in need of a revision arthroplasty. In this sequential study, 67 patients (56 non-stemmed, 11 stemmed) were evaluated after a mean follow-up of 17.5 months. The relative Constant and DASH scores, radiological joint geometry changes, complications and postoperative problems, which are not likely to affect the outcome, were evaluated. A significant increase was noticed for the relative Constant (11.3 vs. 78.8 %) and DASH scores (73.7 vs. 31.8) without significant differences between both etiology groups. Complication rates were similar to previous studies. An aseptic loosening of the non-stemmed humeral component was not noticed in the cuff tear arthropathy group, whereas one case with a loosening was noticed in the revision arthroplasty group. With nine cases (13.4 %), scapular notching rates were very low. On average, the acromiohumeral distance increased by 17 mm and the humeral offset by 13.9 mm; the height of the center of rotation decreased by 4.6 mm and the lateral glenohumeral offset by 6.1 mm, p TESS system provided adequate distalization and medialization of the humerus and the center of rotation. This corresponds to a good clinical outcome. The use of the surgical opportunity to implant the prosthesis with a relatively low neck-shaft angle might explain the low rates of scapular notching in our series. Regarding the case with a loosening of the humeral component, the surgeon should carefully indicate a stemless version for metaphyseal press-fit fixation in patients with revision arthroplasty.

Full Text Available Alkaptonuria is a rare autosomal recessive disorder caused by defective metabolism of homogentisic acid (HGA which on accumulation in the connective tissues causes arthritis, darkening of urine and connective tissue pigmentation. Knee is most commonly affected joint whereas pigment deposition is seen in entire body causing cardiovascular, genitourinary, ocular, cutaneous, and musculoskeletal complications. We here report such a case of bilateral ochronotic arthropathy, who was diagnosed to be alkaptonuric only during joint exploration. He sustained a cardiac catastrophic stroke on 3 rd post operative day of the left knee replacement which was done one week after the right knee replacement. With prompt treatment and good hospital care, the patient was revived successfully, without valvulotomy or valvular replacement. The spectrum of clinical manifestations are discussed in the report with emphasis on thorough history and clinical examination of the patient, before taking the patient to the total knee replacement to make accurate diagnosis before hand and be prepared for the complications or catastrophic by a multidisciplinary approach.

The aim of this study was to define a system for scoring hemophilic arthropathy (HA) based on MR findings, providing for objective evaluation of the degree of joint involvement and evolution after on-demand administration of FVIII substitutional therapy or prophylactic treatment. A total of 133 MR examinations (89 basal and 44 during follow-up) were performed in 25 patients. Patients were divided in two groups depending on the therapy received and the length of time that the disease had been evolving at the start of the study. Group I was composed of 10 patients with secondary prophylaxis and group II was composed by 15 treated on demand. T1-weighted and T2*-weighted images performed on a 0.5-T unit were prospectively evaluated. The joint involvement was established on a scale of 0 (no abnormalities), I (minimal amount of hemosiderin), II (large amount of hemosiderin and isolated cartilaginous erosion), III (cartilage destruction, bone erosions, and subchondral cysts) to IV (large internal joint derangement, secondary osteoarthritis and/or ankylosis). At basal MR examination, patients of group I showed no abnormalities (n=28, 75.6%), grade I (n=3), and grade II (n=6) of HA. Patients of group II corresponded to MR grades III (n=21) and IV (n=11) of HA. The MR follow-up showed improvement in three joints of group I and worsening in 5 joints in group I and 2 joints in group II. Early signs of HA were detected in 10 joints with MR imaging but were underestimated on plain radiographs. Advanced degrees of HA were classified as severe under both imaging techniques. Magnetic resonance is the preferred imaging technique to assess HA. The earliest signs of joint damage, detected by MR, are overlooked by plain radiography. The MR scoring system can be used for evaluating HA. Follow-up MR should be performed to evaluate regression or worsening of the abnormalities, primarily in the case of patients with prophylaxis who usually suffer normal or early joint involvement not

Full Text Available Neuroarthropathy (neuropathic osteoarthropathy, also known as Charcot joint, is a condition characterized by a progressive articular surface destruction in the setting of impaired nociceptive and proprioceptive innervation of the involved joint. It is seen most commonly in the foot and ankle secondary to peripheral neuropathy associated with diabetes mellitus. Cases of hip (Charcot neuroarthropathy are rare and almost exclusively reported in patients with neurosyphilis (tabes dorsalis. We report a case of a 36-year-old man who presented to the emergency department complaining of right hip pain. On physical examination, pain and thermal sensory deficits were noted in the upper torso with a cape-like distribution, as well as signs of an upper motor neuron lesion in the left upper and lower extremities. A magnetic resonance imaging study (MRI of the right hip showed evidence of early articular surface destruction and periarticular edema consistent with hip Charcot arthropathy. An MRI of the spine revealed an Arnold-Chiari type I malformation with extensive syringohydromyelia of the cervical and thoracic spine.

The radiosynoviortesis treatment has been used during more of 40 years as an alternative to the chemical and surgical synovectomy to alleviate the pain and to reduce the inflammation in suffered patients of rheumatic arthropathies, haemophilic arthropathies and other articulation disorders. It consists on the injection of radioactive isotopes inside a synovial cavity. For to evaluate the dosimetry of the radiosynoviortesis treatment is of great interest to know the absorbed dose in the volume of the target (synovia). The precise calculation of the absorbed dose in the inflamed synovia it is difficult, for numerous reasons, since the same one will depend on the thickness of the synovial membrane, the size of the articular space, the structure of the synovial membrane, the distribution in the articulation, the nature of the articular liquid, etc. Also the presence of the bone and the articular cartilage, components also of the articulation, it even complicated more the calculations. The method used to evaluate the dosimetry in radioactive synovectomy is known as the Monte Carlo method. The objective of our work consists on estimating with the Monte Carlo code MCNP4B the absorbed dose of the Y-90 and the P-32 in the depth of the synovial tissue. The results are presented as absorbed dose for injected millicurie (Gy/mCi) versus depth of synovial tissue. The simulation one carries out keeping in mind several synovia areas, of 50 cm{sup 2} to 250 cm{sup 2} keeping in mind three states of progression of the illness. Those obtained values of absorbed dose using the MCNP4B code will allow to introduce in our country an optimized method of dose prescription to the patient, to treat the rheumatic arthritis in medium and big articulations using the Y-90 and the P-32, eliminating the fixed doses and fixed radionuclides for each articulation like it happens in many clinics of Europe, as well as the empiric doses.

To evaluate the clinical and functional behavior of patients undergoing cuff tear arthroplasty at different stages of the disease. Cuff tear arthroplasty hemiarthroplasties were performed in 34 patients with rotator cuff arthropathy and associated comorbidities, classified according to Seebauer. The mean age was 76.3 years, and the sample comprised 23 females (67.6%) and 11 males (32.4%). The mean follow-up period was 21.7 months, and evaluations were performed using the Visual Analog Scale for pain and the Constant scale. There were no statistically significant differences in the mean reduction in the Visual Analog Scale or in the Constant scale increase between the female and male groups. The variation between the pre- and postoperative Visual Analog Scale and Constant scale evaluations was significant. There was also no statistically significant difference between the Seebauer classification groups regarding the mean Visual Analog Scale reduction, or the mean Constant scale increase. Cuff tear arthroplasty shoulder hemiarthroplasty is a good option for rotator cuff arthropathy in patients with comorbidities.

Avaliar, a médio prazo, o resultado do tratamento a que esses pacientes são submetidos seguindo um protocolo preestabelecido. MÉTODOS: Avaliamos, retrospectivamente, 88 pacientes (110 extremidades portadores de artropatia de Charcot do mediopé, com seguimento mínimo de 12 meses. Incluímos os pacientes portadores de artropatia de Charcot acometendo as articulações tarsometatársicas, 45 pacientes (51%; as articulações talonavicular, calcaneocuboide e subtalar, 20 pacientes (23%; e aqueles com envolvimento do mediopé e retropé, 23 pacientes (26%, segundo Brodsky e Trepman. Definimos como sucesso a preservação de um pé funcional e insucesso como amputação do pé. RESULTADOS: O tratamento da artropatia de Charcot envolvendo primariamente o mediopé foram satisfatórios em 75 pacientes (85% tratados seguindo nosso protocolo. Nos pacientes com lesões graves, acometendo tanto o mediopé quanto o retropé, foi necessário maior número de cirurgias complexas do tipo artrodese para se obter o mesmo índice global de resultados satisfatórios. A lesão osteoarticular originada no mediopé provavelmente estende-se progressivamente ao retropé devido à demora no diagnóstico no início do tratamento adequado. CONCLUSÃO: Foi possível preservar uma extremidade funcional em 85% dos pacientes.

Determinants and modifiers of bleeding phenotypes in haemophilia-A: General and tropical perspectives

Full Text Available Haemophilia-A is an X-linked recessive bleeding disorder characterized by deficiency of FVIII. Although severity of haemophilia is largely determined by the extent to which different mutations abolish FVIII production, the overall phenotypic variations among haemophiliacs is determined by a combination of several other factors, which range from general to tropical factors on the one hand, and from genetic to immunologic and infective factors on the other hand. Determinants and modifiers of haemophilic bleeding phenotypes are important predictors of prognosis. However, tropical determinants of haemophilic bleeding phenotypes are virtually ignored because majority of haemophilia research originated from developed non-tropical countries. The aim of this paper is to present a balanced review of the haemophilic bleeding phenotypes from general and tropical perspectives. Hence, we present a concisely updated comprehensive review of the pathophysiologic and clinical significance of general vis-à-vis tropical determinants and modifiers of haemophilic bleeding phenotypes from genetic, immunologic and infective perspectives. Understanding of general phenotypic determinants such as FVIII gene mutations, immunological (inhibitors and infective (e.g. hepatitis and HIV complications, classical thrombophilias (e.g. FV-Leiden and non-classical thrombophilias (e.g. non-O blood groups will throw more light into the mechanisms by which some tropical prothrombotic gene mutations (such as sickle β-globin gene and certain chronic tropical pro-haemorrhagic parasitic infections (such as urinary and gastrointestinal helminthiasis may modify frequency, intensity and pattern of bleeding among haemophiliacs in the tropics. The clinical significance of iron deficiency within the context of helminthiasis and haemophilia is also reviewed. More research is needed to determine the precise effect of non-classical thrombophilias such as sickling disorders and ABO blood groups

In the present study, we aimed to estimate the concentrations of cytokines (interleukin 6, IL-6, tumor necrosis factor-α, TNF-α) and auto-antibodies (rheumatoid factor IgM isotype, IgM-RF, antinuclear auto-antibodies, ANA, anti-cyclic citrullinated peptide antibodies IgG isotype, IgG anti-CCP3.1, anti-cardiolipin IgG isotype, IgG anti-aCL) in serum of patients with eRA (early rheumatoid arthritis) and HCVrA (hepatitis C virus-related arthropathy) and to assess the utility of IL-6, TNF-α together with IgG anti-CCP and IgM-RF in distinguishing between patients with true eRA and HCVrA, in the idea of using them as differential immunomarkers. Serum samples were collected from 54 patients (30 diagnosed with eRA-subgroup 1 and 24 with HCVrA-subgroup 2) and from 28 healthy control persons. For the evaluation of serum concentrations of studied cytokines and auto-antibodies, we used immunoenzimatique techniques. The serum concentrations of both proinflammatory cytokines were statistically significantly higher in patients of subgroup 1 and subgroup 2, compared to the control group ( p < 0.0001). Our study showed statistically significant differences of the mean concentrations only for ANA and IgG anti-CCP between subgroup 1 and subgroup 2. We also observed that IL-6 and TNF-α better correlated with auto-antibodies in subgroup 1 than in subgroup 2. In both subgroups of patients, ROC curves indicated that IL-6 and TNF-α have a higher diagnostic utility as markers of disease. In conclusion, we can say that, due to high sensitivity for diagnostic accuracy, determination of serum concentrations of IL-6 and TNF-α, possibly in combination with auto-antibodies, could be useful in the diagnosis and distinguishing between patients with true eRA and HCV patients with articular manifestation and may prove useful in the monitoring of the disease course.

Full Text Available The peak in incidence of the majority of inflammatory arthropathies (IAs is observed in the 2 nd –4 th decades of life. Thus the diseases affect patients at reproductive age. The results of population studies have demonstrated that these diseases can exert effects on the fertility of the patients, family planning, course of pregnancy and further development of the baby. It has also been shown that female patients with IAs, compared with healthy women, less frequently decide to have the first and other babies and the interval between successive pregnancies is longer. The aim of pharmacotherapy in a patient with IA who plans to become pregnant is to effectively inhibit the inflammatory activity and to maintain remission/low activity of the disease during pregnancy and after its termination. Disease-modifying drugs suitable for administration in the preconception period and pregnancy include: chloroquine, hydroxychloroquine, sulfasalazine, azathioprine, ciclosporin A, glucocorticosteroids and non-steroidal anti-inflammatory drugs. The following should not be administered: out of the synthetic disease-modifying drugs – methotrexate, leflunomide, cyclophosphamide and mycophenolate mofetil; and out of biological drugs – abatacept, tocilizumab and rituximab.

Chronic arthritis is very common and is associated with a variety of systemic diseases whereas hemophilic arthropathy is one of the most common clinical manifestations of hemophilia, mainly of hemophilia type A. All of these polyarticular diseases are associated with progressive pain and increasing lack of mobility. Therapy is based on conservative treatment such as medication with non-steroidal anti-inflammatory drugs, selective therapy strategies such as intraarticular injections of e.g. radioactive substances (radiosynoviorthesis) or surgical interventions. However, in some cases, the disease does not respond to one of these treatment options or cannot be continued due to important side-effects. Systemic application of radioisotopes like {sup 186}Re HEDP has been successfully administered for pain palliation of osseous metastases. Today, only few data exist for systemic therapy with {sup 186}Re HEDP in patients suffering from benign polyarticular disease. In a prospective study with patients suffering from chronic arthritis a single systemic application of {sup 186}Re HEDP led to a reduction of disease activity in six of eight and to a reduction of the number of painful or swollen joints in five of eight included patients. In a further prospective study with 12 patients with hemophilic arthropathy, 19 of 36 (52.7%) most painful joints could be successfully treated with one systemic {sup 186}Re HEDP therapy. Furthermore, a reduction of global pain could be observed in those patients. However, further randomized studies with larger study populations are necessary in order to confirm this promising results. (orig.)

Reverse Total Shoulder Arthroplasty as Treatment for Rotator Cuff-Tear Arthropathy and Shoulder Dislocations in an Elderly Male with Parkinson’s Disease

Full Text Available We report the case of a 70-year-old male with Parkinson’s disease (PD and recurrent traumatic left shoulder dislocations. This case is rare because (1 he had a massive irreparable rotator cuff tear and end-stage arthritis (i.e., rotator cuff-tear arthropathy of the same shoulder and (2 his shoulder was ultimately reconstructed with a reverse total shoulder arthroplasty (RTSA. His first dislocation occurred after a fall. Recurrent shoulder dislocations occurred despite successful closed reduction and physical therapy. Initial surgical treatment included an open capsular-labral reconstruction; RTSA was not an ideal option because of the presumed risk of failure from PD-related dyskinesias. However, the capsular-labral reconstruction failed after he lost balance and stumbled but did not fall. A RTSA was then done which restored the patient’s shoulder stability and greatly improved his pain. At final follow-up two years later, he reported pain relief and improved function. This was partially attributed to the fact that he had moved to an assisted living center. He also began using an electric wheelchair one year after the RTSA. We report this case because of the unusual set of conditions and circumstances, namely, the implantation of a RTSA in a patient with PD and shoulder instability.

The aim of this study was to determine the spectrum of MR findings of presumed amyloid arthropathy of the hip joints in patients on long-term hemodialysis. We prospectively performed T1- and T2-weighted spin-echo imaging on 152 consecutive patients on hemodialysis. The duration of hemodialysis ranged from 5 months to 24 years, 2 months (mean: 8 years, 8 months). The frequency, location, and signal intensity of bone lesions were assessed. In 12 cases with contrast-enhanced MR examination, enhancement pattern of bone lesions, synovial lesions, and intra-articular lesions were characterized. Bone lesions presumed to be amyloid deposits were identified in 60 patients (39 %). Magnetic resonance imaging revealed that amyloid lesions were more extensive than anticipated by plain radiographs. All bone lesions showed decreased signal intensity on T1-weighted images. On T2-weighted images, bone lesions showed increased signal intensity in 32 patients (54 %), decreased signal intensity in 11 patients (18 %), and both increased and decreased signal intensity in 17 patients (28 %). Following intravenous injection of gadolinium-based contrast, all bone lesions showed moderate enhancement. Synovial thickening could not be identified on T1- and T2-weighted images. However, contrast-enhanced images showed thickened synovial membrane, which could be differentiated from joint fluid. Intra-articular nodules showed decreased or intermediate signal intensity on T1-weighted images and decreased signal intensity on T2-weighted images; the intra-articular nodules were contiguous with subchondral bone lesions. Magnetic resonance imaging is useful for evaluating the distribution and extent of amyloidosis of the hip joints in patients undergoing long-term hemodialysis. (orig.) (orig.)

We aimed to estimate the interrelation between preoperative deltoid muscle status by measuring the 3-dimensional deltoid muscle volume and postoperative functional outcomes after reverse total shoulder arthroplasty(RTSA). Thirty-five patients who underwent RTSA participated in this study. All patients underwent preoperative magnetic resonance imaging(MRI) as well as pre- and postoperative radiography and various functional outcome evaluations at least 1 year. The primary outcome parameter was set as age- and sex-matched Constant scores. The 3-dimensional deltoid muscle model was generated using a medical image processing software and in-house code, and the deltoid muscle volume was calculated automatically. Various clinical and radiographic factors comprising the deltoid muscle volume adjusted for body mass index(BMI) were analyzed, and their interrelation with the outcome parameters was appraised using a multivariate analysis. As a result, all practical consequences considerably improved following surgery(all pmuscle volume adjusted for BMI(p = 0.009), absence of a subscapularis complete tear (p = 0.040), and greater change in acromion-deltoid tuberosity distance(p = 0.013) were associated with higher matched Constant scores. Multivariate analysis indicated that the deltoid muscle volume was the single independent prognostic factor for practical consequences(p = 0.011). In conclusion, the preoperative deltoid muscle volume significantly affected the functional outcome following RTSA in patients with cuff tear arthropathy or irreparable cuff tears. Therefore, more attention should be paid to patients with severe atrophied deltoid muscle who are at a high risk for poor practical consequences subsequent to RTSA.

focal changes in calcified cartilage. Ochronosis spreads throughout the cartilage, altering the mechanical properties. In advanced ochronosis, there is aggressive resorption of the underlying calcified cartilage leading to an extraordinary phenotype in which there is complete loss of the subchondral plate. These findings should contribute to better understanding of cartilage-subchondral interactions in arthropathies. Copyright © 2011 by the American College of Rheumatology.

Full Text Available A total of 220 patients with arthropathy were selected in Belém, Pará between January 1994 and December 2000, and screened for the presence of human parvovirus B19 IgM and IgG antibodies by enzyme-linked immunosorbent assay (ELISA. A subgroup (n = 132 of patients with high levels of antibodies (either IgM+/IgG+ or IgM-/IgG+ were examined for the presence of DNA by polymerase chain reaction/nested PCR. Recent/active infection (detection of IgM and/or IgG-specific antibodies and presence of viral DNA was identified in 47.7% of the 132 individuals with arthropathy. In our study, women were significantly more affected (59.7% than men (35.4% (P = 0.0006. The age group of 11-20 years (84.6%, among female patients, and 21-30 years (42.1%, among male, were those with the highest incidence rates. The analysis of the temporal distribution of B19-associated arthropaties showed a cyclic pattern, with peak incidence rates occuring at 3-5 year intervals. Significant diference (P = 0.01 was observed when comparing both the highest (39.0% and the lowest (11.0% seropositivity rates for the years of 1995 and 2000, respectively. The interfalangial joints of hands and feet were mostly affected, with 50.0% and 48.0% of cases among both women and men, respectively. In a smaller proportion, other joints such as those of knee, ankle, pulse and shoulder were affected. As for the duration, symptoms lasted 1 to 5 days in 54.0% of the individuals, whereas in 46.0% of them the disease lasted 6-10 days, if considered the subgroup (n = 63 of patients with recent/active infection by parvovirus B19. In our study, joint clinical manifestations occurred symmetrically. Our results indicate that B19 may be an important agent of arthropathies in our region, and this underscores the need for specific laboratory diagnosis when treating patients suffering from acute arthropathy, mainly pregnant women.Um total de 220 indivíduos portadores de artropatias foi selecionado em Belém, Par

A majority of haemophiliacs who have received large-pool plasma products within the past 5 years have been exposed to the putative agent of the acquired immunodeficiency syndrome (AIDS)--HIV. It is not known what the risk of infection is among patients in South Africa. A study was made of 39 children with congenital coagulation disorders attending the Red Cross War Memorial Children's Hospital Haemophilia Clinic. All but 3 had been treated exclusively with small-pool lyophilised cryoprecipitate or a factor IX concentrate prepared by local blood transfusion services. Three patients had also received imported non-heat-treated commercial products FEIBA (Immuno), Autoplex, Proplex (Hyland) or Factorate (Armour). Absolute lymphocyte counts were normal in all patients but the OKT4/OKT8 ratio was reduced below 1.0 in 9 children including 2 of the 3 who had received commercial plasma concentrates. A high titre of HIV antibody was present in 2 of the 38 patients tested. Both of these children had received imported plasma concentrates and 1 shows some features of the AIDS-related complex. These results suggest that haemophiliacs who receive non-heat-treated commercial concentrates may be at greater risk of HIV infection than patients treated with locally produced plasma products.

Many long-term (>60 months) hemodialysis patients develop a severe osteoarticular disease, called 'dialysis arthropathy', which is characterized by the deposition in bone and synovia of a new type of amyloid made mainly of β 2 -microglobulin. In the present study, 31 patients (17 males, 14 females; age 54.1±13 years) undergoing chronic hemodialysis arthropathy by means of clinics and of radiological investigations (conventional radiography and computed tomography). Sixteen patients (51.6%) had radiographic evidence of dialysis arthropathy: geodes (shoulders, 12 cases; wrists, 11; hips, 2; knees, 2) and/or destructive arthropathies (cervical spine, 13 cases; dorsolumbar spine, 2; hands, 2; hips, 1). Within 24 months, these lesions were found to progress slowly in the majoriry of cases. In the diagnostic process, CT should be employed in the study of spine, shoulders and hips when the lesions have not been sufficiently demonstrated by conventional radiography in the presence of evident clinical signs. Patients with dialysis arthropathy had undergone dialysis for longer periods than those without it (p<0.005) and showed a significantly higher incidence of both carpal tunnel syndrome (p<0.0005) and shoulder pain (p<0.005). Our findings confirm the high incidence and clinical importance of dialysis arthropathy in long-term hemodialysis patients end the value of diagnostic imaging in screening such patients for those lesions

Full Text Available We aimed to estimate the interrelation between preoperative deltoid muscle status by measuring the 3-dimensional deltoid muscle volume and postoperative functional outcomes after reverse total shoulder arthroplasty(RTSA. Thirty-five patients who underwent RTSA participated in this study. All patients underwent preoperative magnetic resonance imaging(MRI as well as pre- and postoperative radiography and various functional outcome evaluations at least 1 year. The primary outcome parameter was set as age- and sex-matched Constant scores. The 3-dimensional deltoid muscle model was generated using a medical image processing software and in-house code, and the deltoid muscle volume was calculated automatically. Various clinical and radiographic factors comprising the deltoid muscle volume adjusted for body mass index(BMI were analyzed, and their interrelation with the outcome parameters was appraised using a multivariate analysis. As a result, all practical consequences considerably improved following surgery(all p<0.01. Overall, 20 and 15 indicated a higher and a lower practical consequence than the average, respectively, which was assessed by the matched Constant scores. The deltoid muscle volume adjusted for BMI(p = 0.009, absence of a subscapularis complete tear (p = 0.040, and greater change in acromion-deltoid tuberosity distance(p = 0.013 were associated with higher matched Constant scores. Multivariate analysis indicated that the deltoid muscle volume was the single independent prognostic factor for practical consequences(p = 0.011. In conclusion, the preoperative deltoid muscle volume significantly affected the functional outcome following RTSA in patients with cuff tear arthropathy or irreparable cuff tears. Therefore, more attention should be paid to patients with severe atrophied deltoid muscle who are at a high risk for poor practical consequences subsequent to RTSA.

Even before the discovery of X-rays in 1895 attempts were being made to classify the joint destruction that occurs in hemophilic arthropathy. The advent of radiography added impetus to the search for the optimum classification system. Subsequent attempts have included advanced imaging methods, especially magnetic resonance imaging (MRI). Because of its high spatial resolution and ability to visualize soft tissue abnormalities, MRI is ideally suited as the best way to classify arthropathy. A literature search was carried out to document and list all the imaging methods for hemophilic arthropathy that have been published up to the present. All published classification systems are discussed and listed in tables. MRI has superior imaging capability and will probably become the most important modality for radiological classification of hemophilic arthropathy in the future.

Prevention of the Musculoskeletal Complications of Hemophilia

Full Text Available Hemophilia is an inherited disorder of clotting factor deficiencies resulting in musculoskeletal bleeding, including hemarthroses, leading to musculoskeletal complications. The articular problems of hemophiliac patients begin in infancy. These include: recurrent hemarthroses, chronic synovitis, flexion deformities, hypertrophy of the growth epiphyses, damage to the articular cartilage, and hemophilic arthropathy. The most commonly affected joints are the ankle, the knee, and the elbow. Hematologic prophylactic treatment from ages 2 to 18 years could avoid the development of hemophilic arthropathy if the concentration of the patient's deficient factor is prevented from falling below 1% of normal. Hemarthroses can be prevented by the administration of clotting factor concentrates (prophylaxis. However, high costs and the need for venous access devices in younger children continue to complicate recommendations for universal prophylaxis. Prevention of joint arthropathy needs to focus on prevention of hemarthroses through prophylaxis, identifying early joint disease through the optimal use of cost-effective imaging modalities and the validation of serological markers of joint arthropathy. Screening for effects on bone health and optimal management of pain to improve quality of life are, likewise, important issues. Major hemarthrosis and chronic hemophilic synovitis should be treated aggressively to prevent hemophilic arthropathy.

The aim of this study was to evaluate the ability of 18 F-fluorodeoxyglucose positron emission tomography/magnetic resonance imaging ( 18 F-FDG PET/MRI) to detect PET-positive cervical facet arthropathy and identify patients who benefit from facet block therapy. Ten patients with cervical facet syndrome (mean age: 65 ± 12 years) underwent 18 F-FDG PET/MRI of the neck. Focal 18 F-FDG uptake in PET-positive facet joints served as target for computed tomography (CT)-guided facet blocks. In PET-negative patients, the target joint for facet block therapy was selected by current clinical standards considering the level of maximum facet arthrosis and pain. Neck pain was measured on visual analogue scale (VAS) before and after therapy. Bone marrow signal intensity (SI) ratio on turbo inversion recovery magnitude (TIRM) images and maximum standard uptake values (SUVmax) was calculated for each facet joint. Pearson's correlation coefficient (r) was calculated between bone marrow SI ratios on TIRM and SUVmax. 18 F-FDG PET/MRI detected PET-positive facet arthropathy in six patients. Patients with PET-positive facet arthropathy had significantly less pain compared with the pretreatment pain 3 h (P = 0.002), 4 weeks (P = 0.002) and 3 months (P = 0.026) after facet block therapy. Pain did not change significantly in patients with PET-negative facet arthropathy. TIRM SI ratio was higher in PET-positive facet arthropathy than in PET-negative facet arthropathy (P < 0.001). Correlation was strong between bone marrow SI ratio on TIRM images and SUVmax (r = 0.7; P < 0.001).

Full Text Available Aim: The aim of this study was to assess and compare the response to two forms of treatment-immobilization with zoledronic acid injection and immobilization with oral weekly Alendronate, in patients with diabetes mellitus and acute Charcot arthropathy (CA of foot in terms of clinical and radiological parameters. Material and Methods: Patients attending the endocrinology and podiatry clinic with history of diabetes mellitus and Acute CA were taken for study. The patients were randomized into two treatment groups. Group Z-zoledronic acid injection along with total contact cast (TCC. Group A-Tab. Alendronate 70 mg. once a week till the complete clinical resolution of acute CA along with TCC. Forty-five patients were randomized and 40 of them completed the study. The primary end point was complete clinical resolution of acute CA-defined as temperature difference between normal and affected foot <1oF. Results: Among the 40 patients, 30 (75% had complete clinical resolution. The mean number of days taken for complete clinical resolution since the initiation of treatment (either Zoledronic acid or Alendronate was approximately 122 days. There was no significant difference in a number of days required for complete clinical resolution, between the two forms of therapy. There was more than 50% reduction in the visual score between the baseline and the final scan. The target to non-target ratio in the skeletal phase also showed an average of 40% reduction from the baseline to the final skeletal scintigraphy. Conclusion: Both Intravenous Zoledronic acid and oral alendronate had comparable efficacy with respect to the time taken for attaining complete clinical resolution of acute CA of foot. However, Alendronate therapy was cost effective among the two. 99m Tc MDP bone scan can be used as an adjuvant to the clinical parameters in assessing the response to therapy.

Synoviorthesis with radioactive gold in hemophiliacs

Ahlberg, Aa.; Petterson, H.

1979-01-01

Twenty-seven patients with hemophilia treated with intra-articular injection of radioactive gold were followed up clinically and radiologically for 3 to 9 years after treatment. To assess the radiological changes, a new classification was designed, with a score describing the severity of the changes in a more accurate manner than the methods previously used. The treatment decreased the bleeding frequency and stopped the progress of the arthropathy if applied at an early stage when the arthropathy was still reversible. If the treatment was begun at a later stage, the arthropathy seemed to progress independently of the effect on the bleeding frequency. No negative effect of the radioactive gold was observed on the joint or the growing zone. (author)

2003-01-01

Radiation Synovectomy is an effective treatment for various kinds of arthropathies with a long history. It is a routine practice in many countries. One of the indications is hemophilic arthropathy, which is caused by repeated hemarthroses and resulting synovial hypertrophy and inflammation. The joints will subsequently be damaged and deformed, leading to significant functional disability. Synovectomy is needed to treat the hypertrophied and inflamed synovium. In this article, the procedure of radiation synovectomy will be elaborated, and a proposed working protocol for hemophilic hemarthrosis will be introduced. Moreover, efficacy (including example of cost effectiveness) of radiation synovectomy will be discussed and showed that the procedure can safely improve patients' symptoms, bleeding episodes, and can control further deterioration of the hemophilic arthropathy

Available literature on the prevalence of Charcot arthropathy (CA) represents mainly Western population. No study has been reported from India so far. Hence we attempted to study the prevalence of CA in patients with type 2 diabetes mellitus and severe peripheral neuropathy (T2DMPN), belonging to Indian population amongst whom type 2 diabetes is on the rise in alarming proportions. Medical records of 3387 patients who performed an objective vibration perception threshold test during the year 2015 were screened for T2DMPN. Out of these, 1475 T2DMPN patients above 50 years were selected and analyzed in detail for CA. CA was diagnosed based on clinical features and/or radiological investigations. The anatomical localization of the disease distribution of the affected foot was done according to Brodsky's classification. The prevalence of CA in T2DMPN patients was found to be 9.8%. The mean age of patients diagnosed with CA was 63 ± 8.36 years, and mean duration of DM for CA to develop was 18.01 ± 8.23 years. About 62.5% of the patients were male and 37.5% female. Bilateral presentation of CA was observed in 20.8% of patients. Multiple sites of the foot were affected in 48.6% of patients and belonged to type 4 classification of Brodsky. A high prevalence of CA (9.8%) was observed in the present study conducted on T2DMPN patients who presented to the endocrinology department of a tertiary care South Indian hospital. In the majority of patients, the area of foot affected belonged to type 4 classification of Brodsky.

We report a distinctive autosomal recessive multicentric osteolysis in Saudi Arabian families with distal arthropathy of the metacarpal, metatarsal and interphalangeal joints, with ultimate progression to the proximal joints with decreased range of movements and deformities with ankylosis and generalized osteopenia. In addition, they had large, painful to touch palmar and plantar pads. Hirsutism and mild dysmorphic facial features including proptosis, a narrow nasal bridge, bulbous nose and micrognathia. Using a genome-wide search for microsatellite markers from 11 members of the family from the Armed Forces Hospital and King Faisal Specialist Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia, localized the disease gene to chromosome 16q12-21. Haplotype analysis with additional markers narrowed the critical region to 1.2cM and identified the matrix metalloproteinase 2 (MMP-2), (gelatinase A, collagenase type IV, EC 3.4, 24,24) gene as a disease candidate at Mount Sinai School of Medicine, New York, United States of America in April 2000. Some affected individuals were homoallelic for a nonsense mutation (TCA>TAA) in codon 244 of exon 5, predicting the replacement of a tyrosine residue by a stop codon in the first fibronectin type II domain (Y244X). Other affected members had a missense mutation in exon 2 arginine 101-histidine (R101H) leading to no MMP-2 enzyme activity in serum or fibroblast or both of affected individuals. In other affected members, a non-pathogenic homoallelic GT transversion resulted in the substitution of an aspartate with a tyrosine residue in codon 210 of exon 4 (D210Y). The MMP-2-null mouse has no developmental defects, but are small, which may reflect genetic redundancy. The discovery that deficiency of this well-characterized gelatinase/collagenase results in an inherited form of an osteolytic and arthritic disorder provides an invaluable insights for the understanding of osteolysis and arthritis and is the first genetic

Knee Fat Pad Volumes in Patients with Hemophilia and Their Relationship with Osteoarthritis

Full Text Available Hemophilic arthropathy is a progressive, disabling condition with poorly understood pathobiology. Since there is an emerging interest to study the role of intra-articular fat pad size and biology in arthritic conditions, we explored fat pad volume changes in hemophilic arthropathy and to what extent they differed from osteoarthritis. We matched a cohort of 13 adult patients with hemophilic arthropathy of the knee with age- and gender-matched cohorts without osteoarthritis (“control cohort” and with the same degree of radiographic osteoarthritis (“OA cohort” in 1 : 2 fashion. Infrapatellar fat pad (IPFP and suprapatellar fat pad (SPFP volumes were calculated based on magnetic resonance imaging and differences in fat pad volumes, demographics, height, weight, and osteoarthritis scores were evaluated. Fat pad volumes were positively associated with body size parameters in all three cohorts but were unaffected by the degree of osteoarthritis. While IPFP volumes did not differ between cohorts, SPFP volumes expanded disproportionally with weight in hemophilia patients. Our observations indicate that IPFPs and SPFPs behave biologically differently in response to different arthritic stimuli. The exaggerated expansion of the SPFP in hemophilia patients highlights the importance of further studying the implications of fat pad biology for progression of hemophilic arthropathy.

Full Text Available Introduction: Patients having severe hemophilia (levels of deficient factor below 1% frequently suffer from disabling chronic arthropathy. An adequate substitution treatment using the coagulation factor VIII or IX concentrates renders an elective surgery feasible. Objective: The objective of the study was to check the results of different surgical procedures in the treatment of hemophilic arthropathies, and to propose the best protocol of their treatment. Methods: This is a retrospective study on 26 hemophilic patients operated in the Orthopedics and Trauma Clinic II, Timisoara, from 2002 to 2005. Elective surgical procedures were mainly performed in the knee (21 arthroscopic procedures, 1 open arthrodesis, elbow (2 open synovectomies, 2 radial head excisions, ankle (1 arthroscopic synovectomy and debridement and thigh (1 giant pseudo tumor excision, other minor procedures. The results after operations on moderate and severe chronic knee, elbow and ankle arthropathy were evaluated, with approximately 24-month follow-up period. Results: Arthroscopic procedures (22 yielded good and satisfactory results with significant improvement according to the evaluation criteria recommended by the World Hemophilia Federation (Gilbert clinical score, Pettersson radiological score, NUSS MRI score. Conclusion: Mini-invasive elective surgery in moderate to severe chronic arthropathy produces good results when performed in a specialized center and with multi-disciplinary approach.

We report for the first time the lack of therapeutic effects after the switch from a brand formulation of allopurinol to a generic one. A 56-year-old man, with a 5 years history of well-treated gout arthropathy with allopurinol (Zyloric(®) 300 mg/die), developed acute gout arthropathy after the switch from the brand formulation of allopurinol to a generic one. Clinical evaluation and laboratory findings confirmed the diagnosis of acute gout arthropathy. Generic formulation of the drug was dismissed and Zyloric(®) was administered with an improvement of both clinical symptoms and laboratory findings. In conclusion, even if generic formulations are considered to have the same effects in comparison to the brand one, more data are necessaries in order to well define their effectiveness and rationale use.

Acute anterior uveitis as the initial presentation of alkaptonuria.

Science.gov (United States)

John, S S; Padhan, P; Mathews, J V; David, S

2009-01-01

Alkaptonuria is a rare autosomal recessive metabolic disorder that may present with multi-system involvement such as ochronotic arthropathy, renal, urethral and prostatic calculi, cardiac valvular lesions and pigmentation of the skin, sclera, cartilage and other connective tissues. An association of the disease with uveitis has never been reported. We report the first case of alkaptonuria with ochronotic arthropathy presenting with recurrent acute anterior uveitis as the initial manifestation. The possible common link with the HLA-B27 gene is discussed.

1990-01-01

The ostearticular involvement in systemic lupus erythematosus (SLE) is the most frequent manifestation of this illness, which develops with activity and remission periods. In spite of the recurrence, it presents without clinic sequelae in great part of the cases. The objective of this study was to evaluate patients with prolonged osteoarticular involvement, remaining with or without sequelae. Within a total of 115 patients with SLE there have been studied 21 patients that presented clinic evidences of chronic synovitis, deforming arthropathy with the presence of cysts, erosions, narrowing of the articular space, periepiphyseal osteopenia, and 4 cases with deforming arthropathy alone. In just 2 cases of chronic synovitis with radiologic changes there have been association with deforming arthropathy. Asseptic necrosis occurred in 8 cases being multiple and symmetric in 7 cases. The association with previous corticosteroid use was found in all patients, as well as an important systemic activity of the illness in the precedent period of the asseptic necrosis diagnosis.

Magnetic resonance imaging in acute and chronic rotator cuff tears

International Nuclear Information System (INIS)

Buirski, G.

1990-01-01

Magnetic resonance imaging has been assessed in patients with acute rotator cuff tears and normal radiographs (9 cases) and those with chronic tears and changes of cuff arthropathy (9 cases). All images were obtained using a low field strength system (FONAR 0.3 T). Particular attention was placed on the appearances of the tendon and the cuff muscles themselves. Six complete acute tears were clearly identified, but MRI failed to demonstrate two partial tears. Muscle bulk was preserved in all patients in this group. In contrast, all patients with cuff arthropathy had complete tears of the supraspinatus tendon with marked tendon retraction and associated muscle atrophy: These changes precluded primary surgical repair. MRI should be used to assess muscle atrophy preoperatively in those patients with acute tears. When plain radiographs demonstrate cuff arthropathy, the MRI appearances are predictable and primary repair is unlikely to be successful. Further imaging is therefore not indicated. (orig.)

Generalised pustular psoriasis, psoriatic arthritis and nephrotic syndrome associated with systemic amyloidosis.

Science.gov (United States)

David, M; Abraham, D; Weinberger, A; Feuerman, E J

1982-09-01

The case report is presented of a psoriatic patient with arthropathy, generalised pustular psoriasis and nephrotic syndrome, in whom systemic amyloidosis developed. The literature reports 13 cases of psoriasis associated with amyloidosis, 3 of whom suffered from pustular psoriasis as does our case. With the addition of our case, 12 of these 14 had concomitant arthropathy. This seems to suggest that arthritis is an important factor in the appearance of amyloidosis. Rectal biopsy and/or renal biopsy may be helpful in establishing the diagnosis of amyloidosis relatively early in patients with psoriatic arthritis.

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.

Rapidly Progressive Osteoarthritis: a Review of the Clinical and Radiologic Presentation.

Science.gov (United States)

Flemming, Donald J; Gustas-French, Cristy N

2017-07-01

The purpose of this paper is to review the distinct clinical and radiographic features that may lead to prompt diagnosis of rapidly progressive osteoarthritis (RPOA) and thus obviate unnecessary and costly diagnostic workup. RPOA is uncommon but is more frequently seen in practice because of the aging population. RPOA is a destructive arthropathy that occurs most commonly in elderly women but can also be seen in patients that have sustained trauma. The dramatic radiologic manifestations of RPOA can lead to diagnostic confusion with other arthropathies, infection, and osteonecrosis. RPOA was originally described in the hip but may also involve the shoulder. The etiology of RPOA is not well understood, but subchondral fracture probably plays a role in the development of dramatic destruction of the joint that is seen in affected patients. Early diagnosis may reduce the complexity of surgical management. RPOA is an uncommon condition that occurs most frequently in elderly woman or in patients who have sustained trauma. Prompt recognition of the clinical and radiologic features of this arthropathy can reduce unnecessary diagnostic workup and complexity of surgical intervention.

1996-01-01

Bone scanning performed in the Nuclear Medicine Center (IPEN-INEN) to patients with neoplastic diagnosis between January 1995 and June 1996, permitted the incidental finding of increased uptake images in the knees of 28 patients associated to an asymptomatic arthropathy: osteoarthritis. The histories and bone scanning of this patients were reviewed obtaining their weight, occupation, symptomatology, neoplastic diagnosis and previous scan diagnosis. Patients under 66 years old, asymptomatic, were included, not presenting secondary focuses, without arthropathia antecedent and with a body mass index equal or above class I. The arthropathy was classified according to the localization of the compromised compartment of the knee. >From the body mass index assessment of every patient it was obtained: Class I=12, Class II=11, Class III=3 and Class IV=1. The predominant localization of the osteoarthritic lesions was the patellar zone. We discuss factors that may influence the absence of symptoms of this disease, the relation obesity-osteoarthritis and the usefulness of bone scanning in the diagnosis of this arthropathy in these patients.

2009-02-01

The main aim of the present study was to determine the sensitivity, specificity and accuracy of ultrasonography (US) in detecting monosodium urate and calcium pyrophosphate dihydrate crystals deposits at knee cartilage level using clinical definite diagnosis as standard reference. A total of 32 patients with a diagnosis of gout and 48 patients with pyrophosphate arthropathy were included in the study. Fifty-two patients with rheumatoid arthritis (RA), psoriatic arthritis or osteoarthritis (OA) were recruited as disease controls. All diagnoses were made using an international clinical criterion. US examinations were performed by an experienced sonographer, blind to clinical and laboratory data. Hyaline cartilage was assessed to detect two US findings recently indicated as indicative of crystal deposits: hyperechoic enhancement of the superficial margin of the hyaline cartilage and hyperechoic spots within the cartilage layer not generating a posterior acoustic shadow. Hyperechoic enhancement of the chondrosynovial margin was found in at least one knee of 14 out of 32 (43.7%) patients with gout and in a single knee of only one patient affected by pyrophosphate arthropathy (specificity=99%). Intra-cartilaginous hyperechoic spots were detected in at least one knee of 33 out of 48 (68.7%) patients with pyrophosphate arthropathy and in two disease controls one with OA and the second with RA (specificity=97.6%). The results of the present study indicate that US may play a relevant role in distinguishing cartilage involvement in patients with crystal-related arthropathy. The selected US findings were found to be highly specific.

This paper classifies the subchondral cysts of the knee joint in young hemophiliacs and studies the evolution of the cyst. Both knees of 64 patients with severe hemophilia A (mean age, 16 years) were assessed with MR imaging (1.5-T Signa, General Electric). Twenty-five patients underwent MR follow-up for 1-4 years. The 258 cysts observed were classified into four types. The LL cysts were seen as areas of low (L) signal intensity on both T1- and T2-weighted images. The LH cysts demonstrated a decreased signal intensity on T1-weighted images and a high (H) signal intensity on T2-weighted images. The HH cysts showed an intermediate to high signal intensity on T1-weighted images and an increased signal intensity on T2-weighted images. The C cysts were complex, showing variable intensity spread out irregularly over the cyst

Background: Diseases exhibiting osteolysis in children are rare hereditary conditions. Several types have been recognised with different clinical manifestations. One type includes subcutaneous nodules, arthropathy and osteolysis and has been termed NAO syndrome. Previous radiological reports have described the affected bones, usually the carpal and tarsal regions, but a detailed analysis of the radiological findings of both the axial as well as the appendicular skeleton has not been reported. Objectives: To describe the radiological findings in a large group of children with an autosomal recessive disease characterized by nodules, familial arthropathy and osteolysis. Materials and methods: The study comprises 14 patients from 9 families and all patients had the triad of nodulosis, arthropathy and osteolysis (NAO). Results: The most common radiological manifestations were osteopenia, undertubulation of long bones, arthritic changes, sclerotic sutures of the calvaria, osteolysis and muscle contractures. Other common findings were squared vertebrae, broad medial clavicles and brachycephaly. Progress of disease was documented in more than half of the patients. Conclusions: Our study is the first report of the detailed radiological findings of NAO syndrome. In NAO syndrome, both the axial and appendicular skeleton are involved (orig.)

Full Text Available Today, major surgical procedures can be safely performed in hemophilic patients with chronic arthropathy, using available factor concentrates. In this setting, total knee replacement is considered the “gold standard”, while the use of total ankle replacement is still debated. Indeed, the unsatisfactory results obtained with the previous available design of implants did not raise enthusiasm as knee or hip replacement. Recently, the introduction of new implant designs and better reported outcomes have renewed the interest in total ankle replacement in people with hemophilia. In this review, the role of replacement surgery in the treatment of chronic hemophilic arthropathy will be described.

Objective: The present study was aimed at describing uncommon presentations of intraosseous hemophilic pseudotumor in imaging diagnosis. Materials and methods: Retrospective study evaluating five hemophilic pseudotumors in bones of two patients with hemophilia A. Imaging findings were consensually evaluated by two musculoskeletal radiologists. Plain radiography, computed tomography and magnetic resonance imaging studies were analyzed. Results: At contrast-enhanced computed tomography images, one of the lesions on the left thigh was visualized with heterogeneously enhanced solid areas. This finding was later confirmed by anatomopathological study. Another uncommon finding was the identification of a healthy bone portion interposed between two intraosseous pseudotumors in the humerus. And, finally, a femoral pseudotumor with extension towards soft tissues and transarticular extension, and consequential tibial and patellar involvement. Conclusion: The above described imaging findings are not frequently reported in cases of intraosseous pseudotumors in hemophilic patients. It is important that radiologists be aware of these more uncommon presentations of intraosseous pseudotumors. (author)

Prevention of arthropathy is a major goal of hemophilia treatment. While studies in adults have demonstrated an impact of prophylaxis on the incidence of joint bleeds and patients' well-being in terms of improved quality of life (QoL), it is unclear whether or not prophylaxis influences the outcome and perception of well- of children with hemophilia. This randomized controlled study compared the efficacy of prophylaxis with episodic therapy in preventing hemarthroses and image-proven joint damage in children with severe hemophilia A (factor VIII <1%) over a 10-year time period. Forty-five children with severe hemophilia A, aged 1-7 years (median 4), with negative clinical-radiologic joint score at entry and at least one bleed during the previous 6 months, were consecutively randomized to prophylaxis with recombinant factor VIII (25 IU kg(-1) 3 × week) or episodic therapy with ≥25 IU kg(-1) every 12-24 h until complete clinical bleeding resolution. Safety, feasibility, direct costs and QoL were also evaluated. Twenty-one children were assigned to prophylaxis, 19 to episodic treatment. Children on prophylaxis had fewer hemarthroses than children on episodic therapy: 0.20 vs. 0.52 events per patient per month (P < 0.02). Plain-film radiology showed signs of arthropathy in six patients on prophylaxis (29%) vs. 14 on episodic treatment (74%) (P < 0.05). Prophylaxis was more effective when started early (≤36 months), with patients having fewer joint bleeds (0.12 joint bleeds per patient per month) and no radiologic signs of arthropathy. This randomized trial confirms the efficacy of prophylaxis in preventing bleeds and arthropathy in children with hemophilia, particularly when it is initiated early in life. © 2011 International Society on Thrombosis and Haemostasis.

Background The main objective of this paper is to analyze the prevalence of each of the different clinical subtypes of temporomandibular disorders (TMD) in a sample of patients with this pathology. In addition, a second objective was to analyze their distribution according to gender. Material and Methods To this end, the results of 1603 patients who went to the Unit of Temporomandibular Disorders in the Córdoba Healthcare District because they suffered from this pathology were analyzed. In order to diagnose them, the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were applied, analyzing the different Axis I subtypes (myopathy, discopathy and arthropathy) and obtaining the combined Axis I for each patient and the relation of all these variables according to gender. The null-hypothesis test confirmed the lack of connection between the gender variable and the different subtypes in the clinical analysis, and between the former and the combined Axis I of the RDC/TMD. Results The prevalence was high for the muscle disorders subtype in general, showing an 88.7% prevalence, while the presence of discopathies or arthropathies was much lower. Among discopathies, the most frequent ones were disc displacements with reduction, with 39.7% and 42.8% for the left and right temporomandibular joints (TMJ), respectively, while the prevalence of arthropathies was 26.3% for the right TMJ and 32.9% for the left TMJ. The bivariate analysis on the connection with gender reveals a p≥ 0.05 value for the muscle and arthralgia subtypes. Conclusions The patients seen at the TMD Unit where mostly middle-aged women whose main clinical axis subtype was the muscle disorder subtype. For their part, both discopathies and arthropathies, although present, are much less prevalent. Key words:RDCTMD, axis I, orofacial pain, temporomandibular disorders, gender. PMID:26615508

Diagnosis of inflammatory rheumatic diseases is besides clinical parameters mainly based on the potential for differential diagnosis of radiographic symptoms obtained by systematic analysis. The initial analysis should emphasize which part of the joint is involved referring to synovial disease, cartilage disease or disease of the enthesis. Synovial arthropathies are assessed regarding soft tissue swelling, soft tissue opacification and the presence of erosions. Cartilaginous pathology is reflected by reduced or increased joint space, calcifications and subchondral bone changes. Enthesopathy is typically located at tendon-ligament and joint capsule attachment, where osteoproliferative but also erosive changes might occur. Lastly, differential diagnosis of arthropathies is mainly based on distribution and allocation of affected joints. (orig.)

Homogentisate 1,2 dioxygenase is expressed in human osteoarticular cells: implications in alkaptonuria.

Alkaptonuria (AKU) results from defective homogentisate1,2-dioxygenase (HGD), causing degenerative arthropathy. The deposition of ochronotic pigment in joints is so far attributed to homogentisic acid produced by the liver, circulating in the blood and accumulating locally. Human normal and AKU osteoarticular cells were tested for HGD gene expression by RT-PCR, mono- and 2D-Western blotting. HGD gene expression was revealed in chondrocytes, synoviocytes, osteoblasts. Furthermore, HGD expression was confirmed by Western blotting, that also revealed the presence of five enzymatic molecular species. Our findings indicate that AKU osteoarticular cells produce the ochronotic pigment in loco and this may strongly contribute to induction of ochronotic arthropathy.

Physiotherapy following elective orthopaedic procedures.

2006-07-01

As haemophilic arthropathy and chronic synovitis are still the most important clinical features in people with haemophilia, different kinds of invasive and orthopaedic procedures have become more common during the last decades. The availability of clotting factor has made arthroplasty of one, or even multiple joints possible. This article highlights the role of physiotherapy before and after such procedures. Synovectomies are sometimes advocated in people with haemophilia to stop repetitive cycles of intra-articular bleeds and/or chronic synovitis. The synovectomy itself, however, does not solve the muscle atrophy, loss of range of motion (ROM), instability and poor propriocepsis, often developed during many years. The key is in taking advantage of the subsequent, relatively safe, bleed-free period to address these important issues. Although the preoperative ROM is the most important variable influencing the postoperative ROM after total knee arthroplasty, there are a few key points that should be considered to improve the outcome. Early mobilization, either manual or by means of a continuous passive mobilization machine, can be an optimal solution during the very first postoperative days. Muscle isometric contractions and light open kinetic chain exercises should also be started in order to restore the quadriceps control. Partial weight bearing can be started shortly after, because of quadriceps inhibition and to avoid excessive swelling. The use of continuous clotting factor replacement permits earlier and intensive rehabilitation during the postoperative period. During the rehabilitation of shoulder arthroplasty restoring the function of the rotator cuff is of utmost importance. Often the rotator cuff muscles are inhibited in the presence of pain and loss of ROM. Physiotherapy also assists in improving pain and maintaining ROM and strength. Functional weight-bearing tasks, such as using the upper limbs to sit and stand, are often discouraged during the first 6

Juxta-articular venous malformations (VMs) are uncommon, but may cause early arthropathy of the knee in children and adolescents. We sought to describe the prevalence, extent and initial magnetic resonance imaging (MRI) features of knee arthropathy in children with VM adjacent to the knee joint. Thirty-five patients with VM adjacent to the knee who had MRI performed between 2000 and 2009 were identified through a keyword search of the radiology information system. VM extended to the joint in 17 of the 35 patients (5.4-21.5 years, mean 11.8 years). Most of these 17 patients had joint changes (15/17, 88%), most commonly haemosiderin deposition (14/17, 82%). Other findings included the presence of subchondral bone lesions (eight, 47%), cartilage loss (six, 35%), synovial thickening (six, 35%), marrow oedema (six, 35%), joint effusion (five, 29%), subchondral cysts (five, 29%) and one loose body (6%). VM location and size did not correlate with the degree of articular involvement. Joint changes were present in focal as well as non-discrete VM. We found that the frequency of arthropathy increased with extension of VM into the joint itself. This finding stresses the importance of early MRI evaluation of all juxta-articular VM. (orig.)

Acute carpal tunnel syndrome (CTS) is a rare surgical condition usually resulting from wrist trauma. We present the case of a young haemophilic man who developed acute CTS following trivial injury. The patient was initially managed conservatively but symptom progression resulted in carpal tunnel decompression. A literature review and management approach are presented. This is an important complication of haemophilia to be aware of as prompt conservative management can obviate the need for surgery. This case is useful in (a) highlighting the importance of considering a patient's medical history when formulating differential diagnoses and (b) outlining a management approach to this condition.

The chronic arthropathies currently appear to be a major cause of disability with a negative impact on quality of life and health care spending. The mud-bath therapy is a spa treatment that induces benefic effects in chronic rheumatic diseases. It has long been debated on the assumption that the mud-bath spa therapy could have adverse cardiovascular effects which often induce caution and even a contraindication to the use of this treatment in chronic arthropathies associated with cardiovascular alterations such as hypertension. The aim of this observational study was to investigate, in arthrorheumatic subjects, the effects of sulphureous mud-bath cycle on blood pressure and the possible appearance of adverse drug reaction. 169 patients, with age range 42-86 years, suffering by chronic arthropathies were treated with sulphureous mud-bath therapy for 2 weeks. According to the arterial pressure values, measured before the spa treatment, the patients considered were divided in three groups: with normal blood pressure (NOR group); with high blood pressure, after, the latter group was divided in IPET (patients in treatment with antihypertensive drugs) and IPENT (patients not in antihypertensive therapy). The arterial pressure values, maximum and minimum, expressed in mmHg, were detected in the first (T1) - sixth (T6) and twelfth (T12) day of spa treatment.

A multicentre, international, cross-sectional study was carried out in the frame of field testing of the first haemophilia-specific quality-of-life (QoL) questionnaire (Haemo-QoL). The aim of this paper is to describe health status and health care and their impact on QoL in haemophilic children in Western Europe. Children aged 4-16 years with severe haemophilia without inhibitors were enrolled by 20 centres in France, Germany, Italy, the Netherlands, Spain and the United Kingdom. Clinical information was collected by the physicians with a medical documentation form. Health-related QoL (HRQoL) of children was assessed with Haemo-QoL, available for three age groups. Clinical data were available in 318 patients, 85.5% with haemophilia A. The mean age at first bleeding was 11 months, at first joint bleed 25 months. Functional joint impairments were found in 11.3%. Prophylaxis treatment was given to 66.7% of children in whom breakthrough bleeds occurred 0.4 times a month compared to 1.1 bleeds in children receiving on-demand treatment. A significantly higher factor consumption was found only in the two younger age groups of prophylaxis patients compared to on-demand patients. HRQoL was satisfactory in this cohort: young children were impaired mainly in the dimension 'family' and 'treatment', whereas older children had higher impairments in the so-called 'social' dimensions, such as 'perceived support' and 'friends'. Health care of children in Western Europe is progressively improving with a large diffusion of home treatment and prophylaxis. This provides a high level of health status and HRQoL, being better in haemophilic adolescents on prophylaxis.

The authors report a case of a 49 years-old male patient with emphasis in the arthropathy of hemochromatosis. The arthropathy was the first manifestation: the patient had been complaining of pain on the right hip for eight years. The other specific clinical manifestations: diabetes, abnormal pigmentation appeared after six years. The roentgenographic features of bone and joint involvement include abnormalites at metacarpophalangeal joints with osteophytes on the metacarpal heads and in the hip, joint space narrowing, was seen. In the knee involvement is characterized by subchondral cyst and osteophytosis. Laboratory analysis are: serum iron = 191 mg/dl (normal value: 50-150 mg/dl), ferritin > 400 ng/ml (normal value: 42-26 ng/ml). Iron within the parenchymal cells of the liver cirrhosis was detected by hepatic biopsy. Hemochromatosis was pathologically characterized by tissue damage produced by iron deposition. (author) [pt

Arthrography provides accurate information concerning abnormal changes and function of the soft tissue components of the T.M.J. It is superior to all other clinical and radiological methods of examination for elucidating functional abnormalities. The increasing incidence of functional T.M.J. abnormalities and improvements in treatment make arthrography of the T.M.J. of increasing importance. The importance of views in the sagittal plane and of video recordings is stressed. 3 figs.

Full Text Available [english] Nail-patella syndrome (NPS is a pleiotropic autosomal-dominant disorder due to mutations in the gene LMX1B. It has traditionally been characterized by a tetrad of dermatologic and musculoskeletal abnormalities. However, one of the most serious manifestations of NPS is kidney disease, which may be present in up to 40% of affected individuals. Although diagnosis can be made at birth, it is often missed, presumably due to the rarity of the condition. A 35-year-old female presented to our clinic with history of small joint pain of 6 months duration. In addition she complained of pedal edema off and on for the last 12 years. Prior to her current presentation she had been managed by a local doctor symptomatically. On evaluation, a nephrotic syndrome was obvious, but no secondary cause could be found. However, her physical examination was characteristic of NPS and keeping in view the autosomal dominant nature of the disorder all her three siblings were screened who too showed classical features of NPS. This rare syndrome as a cause of nephrotic range proteinuria is discussed in this report. The report underlines the importance of a good physical examination in a given clinical setting.

The role of recombinant activated factor VII in the haematological management of elective orthopaedic surgery in haemophilia A patients with inhibitors

Science.gov (United States)

Castaman, Giancarlo

2017-01-01

The clinical profile and expectations of haemophilic patients with inhibitors have changed over the last three decades, mainly because of the prolongation of life-expectancy, often resulting in an increase of the orthopaedic burden. Recombinant activated factor VII (rFVIIa) is the most frequently used bypassing agent in haemophilia patients with inhibitors during elective orthopaedic surgery. For nearly 30 years, rFVIIa has been successfully used to control haemostasis in several major and minor surgical procedures. Clinical trials, case series, reports and surveys were progressively aimed at optimising rFVIIa usage in very demanding conditions managed in highly specialised centres. Recommendations from consensus opinions and guidelines have been provided on the basis of this clinical experience. PMID:28686157

Alkaptonuria (AKU) is an ultra-rare disease associated to the lack of an enzyme involved in tyrosine catabolism. This deficiency results in the accumulation of homogentisic acid (HGA) in the form of ochronotic pigment in joint cartilage, leading to a severe arthropathy. Secondary amyloidosis has been also unequivocally assessed as a comorbidity of AKU arthropathy. Composition of ochronotic pigment and how it is structurally related to amyloid is still unknown. We exploited Synchrotron Radiation Infrared and X-Ray Fluorescence microscopies in combination with conventional bio-assays and analytical tools to characterize chemical composition and morphology of AKU cartilage. We evinced that AKU cartilage is characterized by proteoglycans depletion, increased Sodium levels, accumulation of lipids in the peri-lacunar regions and amyloid formation. We also highlighted an increase of aromatic compounds and oxygen-containing species, depletion in overall Magnesium content (although localized in the peri-lacunar region) and the presence of calcium carbonate fragments in proximity of cartilage lacunae. We highlighted common features between AKU and arthropathy, but also specific signatures of the disease, like presence of amyloids and peculiar calcifications. Our analyses provide a unified picture of AKU cartilage, shedding a new light on the disease and opening new perspectives. Ochronotic pigment is a hallmark of AKU and responsible of tissue degeneration. Conventional bio-assays have not yet clarified its composition and its structural relationship with amyloids. The present work proposes new strategies for filling the aforementioned gap that encompass the integration of new analytical approaches with standardized analyses. Copyright © 2017 Elsevier B.V.

Limited reliability data exist for localised magnetic resonance imaging (MRI) findings relevant to planning of treatment with lumbar disc prosthesis and later outcomes. We assessed the reliability of such findings in chronic low back pain patients who were accepted candidates for disc prosthesis. On pretreatment MRI of 170 patients (mean age 41 years; 88 women), three experienced radiologists independently rated Modic changes, disc findings and facet arthropathy at L3/L4, L4/L5 and L5/S1. Two radiologists rerated 126 examinations. For each MRI finding at each disc level, agreement was analysed using the kappa statistic and differences in prevalence across observers using a fixed effects model. All findings at L3/L4 and facet arthropathy at L5/S1 had a mean prevalence <10% across observers and were not further analysed, ensuring interpretable kappa values. Overall interobserver agreement was generally moderate or good (kappa 0.40-0.77) at L4-S1 for Modic changes, nucleus pulposus signal, disc height (subjective and measured), posterior high-intensity zone (HIZ) and disc contour, and fair (kappa 0.24) at L4/L5 for facet arthropathy. Posterior HIZ at L5/S1 and severely reduced subjective disc height at L4/L5 differed up to threefold in prevalence between observers (p < 0.0001). Intraobserver agreement was mostly good or very good (kappa 0.60-1.00). In candidates for disc prosthesis, mostly moderate interobserver agreement is expected for localised MRI findings. (orig.)

Pain associated with poultry lameness is poorly understood. The anti-nociceptive properties of two non-steroidal anti-inflammatory drugs (NSAIDs) were evaluated using threshold testing in combination with an acute inflammatory arthropathy model. Broilers were tested in six groups (n = 8 per group). Each group underwent a treatment (saline, meloxicam (3 or 5 mg/kg) or carprofen (15 or 25 mg/kg)) and a procedure (Induced (arthropathy-induction) or sham (sham-handling)) prior to testing. Induced groups had Freund’s complete adjuvant injected intra-articularly into the left intertarsal joint (hock). A ramped thermal stimulus (1 °C/s) was applied to the skin of the left metatarsal. Data were analysed using random-intercept multi-level models. Saline-induced birds had a significantly higher skin temperature (± SD) than saline-sham birds (37.6 ± 0.8 °C vs. 36.5 ± 0.5 °C; Z = −3.47, P carprofen: Z = 2.58, P = 0.010) in induced birds. Saline-induced birds also had significantly lower TT than saline-sham birds (Z = −2.17, P = 0.030). This study found direct evidence of an association between inflammatory arthropathies and thermal hyperalgesia, and showed that NSAID treatment maintained baseline thermal sensitivity (via anti-nociception). Quantification of nociceptive responsiveness in a predictable broiler pain model identified thermal anti-hyperalgesic properties of two NSAIDs, which suggested that therapeutically effective treatment was provided at the doses administered. Such validation of analgesic strategies will increase the understanding of pain associated with specific natural broiler lameness types. PMID:24129110

To evaluate the MRI findings in the lumbar spines of asymptomatic elite junior tennis players. The lumbar spine MRI studies of 98 asymptomatic junior elite tennis players (51 male, 47 female) with a mean age of 18 years (age range 11.2-26.3 years; standard deviation 3.1) was reviewed by two consultant musculoskeletal radiologists using consensus opinion. Images were assessed using accepted classification systems. Four players (4 %) had no abnormality. Facet joint arthropathy occurred in 89.7 % of the players, being mild in 84.5 % of cases. There were 41 synovial cysts in 22.4 % of the cohort all occurring in the presence of facet arthropathy. Disc degeneration was noted in 62.2 % of players, being mild in 76.2 % of those affected. Disc herniation was noted in 30.6 % of players, with 86.1 % of these being broad based and 13.9 % being focal. There was nerve root compression in 2 %. There were 41 pars interarticularis abnormalities in 29.6 % of patients, 63.4 % of these being grades 1-3. There was grade 1 spondylolisthesis in 5.1 % of players. The prevalence of facet joint arthropathy, disc degeneration, disc herniation and pars interarticularis fracture was lower in female players than in male and lower in the under 16-year-olds compared with the over 20-year-olds. There is a significant amount of underlying pathology that would normally go undetected in this group of asymptomatic elite athletes. Whilst these findings cannot be detected clinically, their relevance is in facilitating appropriate prehabilitation to prevent loss of playing time and potentially career-ending injuries. (orig.)

2008-03-01

Ankle fractures in patients with diabetes mellitus have long been recognized as a challenge to practicing clinicians. Complications of impaired wound healing, infection, malunion, delayed union, nonunion, and Charcot arthropathy are prevalent in this patient population. Controversy exists as to whether diabetic ankle fractures are best treated noninvasively or by open reduction and internal fixation. Patients with diabetes are at significant risk for soft-tissue complications. In addition, diabetic ankle fractures heal, but significant delays in bone healing exist. Also, Charcot ankle arthropathy occurs more commonly in patients who were initially undiagnosed and had a delay in immobilization and in patients treated nonsurgically for displaced ankle fractures. Several techniques have been described to minimize complications associated with diabetic ankle fractures (eg, rigid external fixation, use of Kirschner wires or Steinmann pins to increase rigidity). Regardless of the specifics of treatment, adherence to the basic principles of preoperative planning, meticulous soft-tissue management, and attention to stable, rigid fixation with prolonged, protected immobilization are paramount in minimizing problems and yielding good functional outcomes.

2017-09-01

Arthritis resulting from recurrent intra-articular bleeding in individuals with hemophilia can be severely debilitating due to joint pain and stiffness with subsequent loss of mobility and function. Very limited studies have investigated the potential benefits of joint mobilization for this condition. This case series is a preliminary investigation of safety, as well as immediate and short-term clinical benefits, associated with gentle knee and ankle joint mobilization in people with hemophilic arthropathy. A single intervention of joint mobilization was applied to the affected knees and/or ankles of 16 individuals with severe or moderate hemophilia within a public hospital setting. Adverse events, as well as immediate (pain-free passive joint range, Timed Up and Go Test with maximum pain numerical rating scale) and short-term (Lower Extremity Functional Scale) effects of the intervention were evaluated with a repeated measures ANOVA. There were no adverse events. An immediate significant increase was observed in pain-free passive ankle joint range of motion ( p  < 0.05) following the joint mobilization intervention. The findings of this case series suggest that gentle joint mobilization techniques may be safely considered as part of a multimodal management approach for hemophilic arthropathy.

The aim of the study was to study the prevalence of juvenile idiopathic arthritis (JIA) in school children in the city of Embu das Artes in São Paulo State. 2880 school children from seven public schools, aged between 6 and 12 years, were evaluated (clinical findings) by a pediatric rheumatologist. A board certified Pediatric Rheumatologist evaluated the subjects with suspected inflammatory arthropathy. Children with higher suspicion were referred to a specialized service. One hundred and forty-one children have presented abnormalities on examination of musculoskeletal system, with isolated pain on palpation the most common finding in the first evaluation (60.9%), with improvement in almost all cases in the second examination. Most of the abnormalities were related to recent injuries or congenital malformations. Six children have clinical findings suggestive of chronic arthropathy and were referred to a specialized pediatric rheumatology clinic. Of these, a 12 year-old girl fulfilled the criteria for JIA. The other diagnoses were aseptic necrosis of the hip (P = 1) of and post-trauma synovitis (P = 4). The prevalence of JIA in children aged between 6 and 12 years was 1/2.880 (or 0.34/1.000).

To compare the cost-effectiveness within the United States health care system of arthroscopic rotator cuff repair versus reverse total shoulder arthroplasty in patients with symptomatic large and massive rotator cuff tears without cuff-tear arthropathy. An expected-value decision analysis was constructed comparing the costs and outcomes of patients undergoing arthroscopic rotator cuff repair and reverse total shoulder arthroplasty for large and massive rotator cuff tears (and excluding cases of cuff-tear arthropathy). Comprehensive literature search provided input data to extrapolate costs and health utility states for these outcomes. The primary outcome assessed was that of incremental cost-effectiveness ratio (ICER) of reverse total shoulder arthroplasty versus rotator cuff repair. For the base case, both arthroscopic rotator cuff repair and reverse total shoulder were superior to nonoperative care, with an ICER of $15,500/quality-adjusted life year (QALY) and $37,400/QALY, respectively. Arthroscopic rotator cuff repair was dominant over primary reverse total shoulder arthroplasty, with lower costs and slightly improved clinical outcomes. Arthroscopic rotator cuff repair was the preferred strategy as long as the lifetime progression rate from retear to end-stage cuff-tear arthropathy was less than 89%. However, when the model was modified to account for worse outcomes when reverse shoulder arthroplasty was performed after a failed attempted rotator cuff repair, primary reverse total shoulder had superior outcomes with an ICER of $90,000/QALY. Arthroscopic rotator cuff repair-despite high rates of tendon retearing-for patients with large and massive rotator cuff tears may be a more cost-effective initial treatment strategy when compared with primary reverse total shoulder arthroplasty and when assuming no detrimental impact of previous surgery on outcomes after arthroplasty. Clinical judgment should still be prioritized when formulating treatment plans for these

Quinolones (QNs)-induced arthropathy is an important toxic side-effect in immature animals leading to the restriction of their therapeutic use in pediatrics. Ofloxacin, a typical QN, was found to induce the chondrocytes apoptosis in the early phase (12–48 h) of arthropathy in our previous study. However, the exact mechanism(s) is unclear. Microencapsulated juvenile rabbit joint chondrocytes, a three-dimensional culture system, is utilized to perform the present study. Ofloxacin, at a therapeutically relevant concentration (10 μg/ml), disturbs the interaction between β1 integrin and activated intracellular signaling proteins at 12 h, which is inhibited when supplementing Mg 2+ . Intracellular reactive oxygen species (ROS) significantly increases in a time-dependent manner after exposure to ofloxacin for 12–48 h. Furthermore, ofloxacin markedly enhances the level of activated Rac1 and epidermal growth factor receptor (EGFR) phosphorylation, and its inhibition in turn reduces the ROS production, apoptosis and Rac1 activation. Silencing Nox2, Rac1 or supplementing Mg 2+ inhibits ROS accumulation, apoptosis occurrence and EGFR phosphorylation induced by ofloxacin. However, depletion of Nox2, Rac1 and inhibition of EGFR do not affect ofloxacin-mediated loss of interaction between β1 integrin and activated intracellular signaling proteins. In addition, ofloxacin also induces Vav2 phosphorylation, which is markedly suppressed after inactivating EGFR or supplementing Mg 2+ . These results suggest that ofloxacin causes Nox2-mediated intracellular ROS production by disrupting the β1 integrin function and then activating the EGFR-Vav2-Rac1 pathway, finally resulting in apoptosis within 12–48 h exposure. The present study provides a novel insight regarding the potential role of Nox-driven ROS in QNs-induced arthropathy. - Highlights: ► Ofloxacin induces Nox2-driven ROS in encapsulated chondrocyte at 12–48 h. ► Ofloxacin stimulates ROS production via the β1

To investigate the surgical technique and the clinical results of total knee arthroplasty (TKA) in treating end-stage gonarthrosis combined with valgus knee deformity. Between November 1998 and October 2010, 64 patients (72 knees) with end-stage gonarthrosis combined with valgus knee deformity underwent TKA by a medial parapatellar approach. Of the 64 patients, 18 were male and 46 were female with an average age of 62.5 years (range, 23-82 years), including 44 cases (49 knees) of osteoarthritis, 17 cases (20 knees) of rheumatoid arthritis, 2 cases (2 knees) of haemophilic arthritis, and 1 case (1 knee) of post-traumatic arthritis. Bilateral knees were involved in 8 cases, and single knee in 56 cases. The flexion and extension range of motion (ROM) of the knee joint was (82.2 +/- 28.7) degrees; the femur-tibia angle (FTA) was (18.0 +/- 5.8) degrees; according to Knee Society Score (KSS) criterion, the preoperative clinical score was 31.2 +/- 10.1 and functional score was 37.3 +/- 9.0. According to Krackow's classification, there were 65 knees of type I and 7 knees of type II. By medial parapatellar approach, conventional osteotomy and Ranawat soft tissue release were performed in all cases. Prosthesis of preserved posterior cruciate ligament were used in 7 cases (7 knees), posterior stabilize prosthesis in 54 cases (60 knees), constrained prosthesis in 4 cases (5 knees). Incisions healed by first intention in all cases. Peroneal nerve palsy occurred in 1 patient with haemophilic arthritis, severe valgus deformity (FTA was 41 degrees), and flexion contracture (20 degrees), which was cured after 1 year of conservative treatment. Revison surgery was performed in 1 case of deep infection at 2 years after surgery. All the patients were followed up 4.9 years on average (range, 1-13 years). At last follow-up, the FTA was (7.0 +/- 2.5) degrees, showing significant difference when compared with preoperative value (t = 15.502, P = 0.000). The KSS clinical score was 83.0 +/- 6

We report a case of a 53-year-old man presenting with shoulder pain mimicking septic arthritis. Laboratory findings were atypical. Biopsy performed to assess for possible osteomyelitis demonstrated chronic lymphocytic leukemia/small lymphocytic lymphoma. Intra-articular lymphoma is a rare but important consideration in patients with atypical clinical presentation. Imaging alone may be insufficient to render diagnosis as lymphoma can mimic infection, synovial hypertrophic processes, and depositional arthropathy. (orig.)

Periarticular uptake of /sup 99m/technetium diphosphonate in psoriatics. Correlation with cutaneous activity

International Nuclear Information System (INIS)

Namey, T.C.; Rosenthall, L.

1976-01-01

The periarticular uptake of /sup 99m/technetium-labeled diphosphonate (/sup 99m/TcDP) was compared in 12 patients hospitalized for psoriasis and in 12 hospitalized for other dermatoses not associated with arthropathy. The 12 patients with psoriasis had recent onset disease of less than 5 years duration; neither group had historical or clinical evidence of arthritis. All psoriatics had markedly abnormal scans with symmetrically increased periarticular uptake about the imaged joints. None of the controls had similar findings. In 4 patients scanned with /sup 99m/technetium-pertechnetate within 24 hours of their /sup 99m/TcDP scan, no evidence of inflammatory synovitis was found. Three of these patients were serially imaged with /sup 99m/TcDP at intervals of 2 weeks to 3 months after their initial study, when obvious clinical improvement in their psoriasis was apparent. Improvement in the radionuclide joint images was demonstrated in some of the patients, but none reverted to normal during the study period. In light of recent evidence for the preferential binding of /sup 99m/TcDP to immature collagen, it is suggested that psoriasis may represent a generalized, but uncharacterized, collagen disorder present in bone as well as skin, linking the cutaneous disease with the potential for arthropathy

Prevention of hemarthrosis is the key factor in the adequate management of people with hemophilia (PWH). If hemarthrosis occurs, early diagnosis of joint damage is essential to make personalized treatments. This study is aimed at gaining an understanding of the ability of point-of-care ultrasound (US) using the `Hemophilia Early Arthropathy Detection with Ultrasound´ (HEAD-US) protocol to detect abnormalities in joints without history of hemarthrosis and clinically asymptomatic joints of PWH. The sample included 976 joints from 167 PWH (mean age 24.86 years). Data were collected from routine practice over a 3-year period and analyzed based on history of hemarthrosis and results of clinical (HJHS 2.1) and HEAD-US examinations. In our series, 14% of patients exhibited HEAD-US signs of incipient arthropathy in joints with no history of bleeding and with a HJHS 2.1 score of 0. The most severely involved joint was the right ankle. Synovitis, articular cartilage and subchondral bone damage scores in joints with subclinical findings were slower than in joints with previous hemarthroses or HJHS 2.1 > 1 Conclusions: Our study demonstrates that HEAD-US is better than hemarthrosis records and the HJHS 2.1 scale in detecting the early signs of joint damage in PWH.

It is known that successful pancreas transplantation enables patients with diabetes to maintain a normal glucose level without insulin and reduces diabetes-related complications. However, we have little information about the foot-specific morbidity in patients who have undergone successful pancreas transplantation. The purpose of this study was to investigate the prevalence and predisposing factors for foot complications after successful pancreas transplantation. This retrospective study included 218 patients (91 males, 127 females) who had undergone pancreas transplantation for diabetes. The mean age was 40.7 (range, 15-76) years. Diabetes type, transplantation type, body mass index, and diabetes duration before transplantation were confirmed. After pancreas transplantation, the occurrence and duration of foot and ankle complications were assessed. Twenty-two patients (10.1%) had diabetic foot complications. Fifteen patients (6.9%) had diabetic foot ulcer and 7 patients (3.2%) had Charcot arthropathy. Three patients had both diabetic foot ulcer and Charcot arthropathy. Three insufficiency fractures (1.4%) were included. Mean time of complications after transplantation was 18.5 (range, 2-77) months. Creatinine level 1 year after surgery was higher in the complication group rather than the noncomplication group ( P = .02). Complications of the foot and ankle still occurred following pancreas transplantation in patients with diabetes. Level III, comparative study.

The incidence of tertiary syphilis involvement in the spinal column with destructive bone lesions is very rare. It is difficult to establish the correct diagnosis from radiographs and histological examination alone. Limited data are available on surgical treatment to tertiary syphilitic spinal lesions. In this article, we report a case of tertiary syphilis in the lumbar spine with osteolytic lesions causing cauda equina compression. A 44-year-old man who suffered with low back pain for 6 months and progressive radiating pain at lower extremity for 1 week. Radiologic findings showed osteolytic lesion and new bone formation in the parts of the bodies of L4 and L5. Serum treponema pallidum hemagglutination (TPHA) test was positive. A surgery of posterior debridement, interbody and posterolateral allograft bone fusion with instrumentation from L3 to S1 was performed. The low back pain and numbness abated after operation. But the follow-up radiographs showed absorption of the bone grafts and failure of instrumentation. A Charcot's arthropathy was formed between L4 and L5. It is challenging to diagnose the tertiary syphilis in the spine. Surgery is a reasonable auxiliary method to antibiotic therapy for patients who suffered with neuropathy. Charcot's arthropathy should be considered as an operative complication.

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/mm 2 ), 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 cm 2 /s) relative to patients with effusions accompanying knee trauma (greater than 2.75 x 10 -5 cm 2 /s) and inflammatory arthritis (in vitro and in vivo greater than 3.00 x 10 -5 cm 2 /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.)

Full Text Available We report a young man with gouty discitis of the cervical spine. To our knowledge, our patient is the youngest patient with cervical gouty discitis reported in the literature. The clinical manifestation was similar to that of cervical spondylosis with radiculopathy. Gouty discitis was diagnosed only when tophi in the disc were found during surgery and proved by pathologic study. Surgical decompression followed by optimization of pharmacologic treatment enabled good recovery from neurologic complications.

A synovial cyst of the hip joint is a rare cause of unilateral leg edema, and it is usually associated with arthropathies such as rheumatoid arthritis and osteoarthritis. An asymptomatic synovial cyst of the hip joint that is not associated with an arthritic condition occurs infrequently. In this paper, we described the case of a 52-year-old woman who presented with unilateral right leg edema caused by a synovial cyst of the hip joint.

The authors report a case of calcium oxalate arthropathy in a woman undergoing intermittent peritoneal dialysis who was not receiving pharmacologic doses of ascorbic acid. She developed acute arthritis, with calcium oxalate crystals in Heberden's and Bouchard's nodes, a phenomenon previously described in gout. Intermittent peritoneal dialysis may be less efficient than hemodialysis in clearing oxalate, and physicians should now consider calcium oxalate-associated arthritis in patients undergoing peritoneal dialysis who are not receiving large doses of ascorbic acid

de Graaff, Barbara; Neil, Amanda; Sanderson, Kristy; Si, Lei; Yee, Kwang Chien; Palmer, Andrew J

2015-10-01

Hereditary haemochromatosis (HH) is a common genetic condition amongst people of northern European heritage. HH is associated with increased iron absorption leading to parenchymal organ damage and multiple arthropathies. Early diagnosis and treatment prevents complications. Population screening may increase early diagnosis, but no programmes have been introduced internationally: a paucity of health economic data is often cited as a barrier. To conduct a systematic review of all health economic studies in HH. Studies were identified through electronic searching of economic/biomedical databases. Any study on HH with original economic component was included. Study quality was formally assessed. Health economic data were extracted and analysed through narrative synthesis. Thirty-eight studies met the inclusion criteria. The majority of papers reported on costs or cost effectiveness of screening programmes. Whilst most concluded screening was cost effective compared with no screening, methodological flaws limit the quality of these findings. Assumptions regarding clinical penetrance, effectiveness of screening, health-state utility values (HSUVs), exclusion of early symptomatology (such as fatigue, lethargy and multiple arthropathies) and quantification of costs associated with HH were identified as key limitations. Treatment studies concluded therapeutic venepuncture was the most cost-effective intervention. There is a paucity of high-quality health economic studies relating to HH. The development of a comprehensive HH cost-effectiveness model utilising HSUVs is required to determine whether screening is worthwhile.

Alkaptonuria, more than just a mere disease

Directory of Open Access Journals (Sweden)

Abdul Qayyum Rana

2015-01-01

Full Text Available Alkaptonuria (AKU is considered a rare autosomal recessive condition that results in an accumulation of homogentisic acid in body tissues and causes long-term clinical, neurological and psychological complications. We present a comprehensive evaluation of an atypical 46-year-old Caucasian male who developed all clinical diagnostic symptoms of AKU (ochronotic pigmentations, dark urine and clinical arthritis of major joints including spine by 25 years of age, well before the typical age mentioned in many reviews. First signs of ochronotic ear pigmentations unexpectedly started appearing as early as 12 years of age. A long "disease-free" period typical in classical AKU patient was also absent. This case report highlights the importance of considering psychological issues in AKU patients. The patient showed symptoms of dysthymia reporting social isolation, diminished interest in pleasurable activities, feeling of worthlessness and irritability as major psychological issues. Early ochronotic pigmentation, advanced spinal myelopathy and arthropathy of major joints suggests aggressive course of the disease. Our patient underwent bilateral shoulder replacement due to AKU-induced arthropathy resulting in restoration of some range of motions. AKU is not fully understood and we recommend treating it as a multidimensional disease with simultaneous physiological, neurological and psychological effects. Early diagnosis, understanding of disease prognosis and emphasis on psychological health is needed to improve the quality of life of AKU patients.

Recent evidence suggests that patients with severe hemophilia B may have a less severe disease compared to severe hemophilia A. To investigate clinical, radiological, laboratory and histological differences in the arthropathy of severe hemophilia A and hemophilia B, 70 patients with hemophilia A and 35 with hemophilia B with at least one joint bleeding were consecutively enrolled. Joint bleedings (50), regimen of treatment (prophylaxis/on demand), World Federation of Hemophilia, Pettersson and ultrasound scores, serum soluble RANK ligand and osteoprotegerin were assessed in all patients. RANK, RANK ligand and osteoprotegerin expression was evaluated in synovial tissue from 18 hemophilia A and 4 hemophilia B patients. The percentage of patients with either 10-50 or more than 50 hemarthrosis was greater in hemophilia A than in hemophilia B (Phemophilia B (PHemophilia (36.6 vs. 20.2; Phemophilia A patients. Serum osteoprotegerin and soluble RANK ligand were decreased in hemophilia A versus hemophilia B (Phemophilia A patients. In conclusion, the reduced number of hemarthrosis, the lower World Federation of Hemophilia and ultrasound scores, and higher osteoprotegerin expression in serum and synovial tissue in hemophilia B suggest that hemophilia B is a less severe disease than hemophilia A. Osteoprotegerin reduction seems to play a pivotal role in the progression of arthropathy in hemophilia A. Copyright© Ferrata Storti Foundation.

Chaturvedi, Arti; Chaturvedi, Sunil; Sivasankar, Rajiv

2009-01-01

To assess the efficacy of facet joint infiltrations for pain relief in 44 selected patients with chronic nonradicular low back pain (LBP). Forty-four patients with chronic LBP of more than 3 months' duration were selected for facet joint infiltration. The majority (n = 24) had facetal pain with no evidence of significant facetal arthropathy on imaging. Fifteen patients had radiological evidence of facetal arthropathy, one had a facet joint synovial cyst, three were post–lumbar surgery patients, and two patients had spondylolysis. Facet joint injections were carried out under fluoroscopic guidance in 39 patients and under CT guidance in 5 cases. Pain relief was assessed using the visual analog scale at 1 h post-procedure and, thereafter, at 1, 4, 12, and 24 weeks. A total of 141 facet joints were infiltrated in 44 patients over a 2-year period. There was significant pain relief in 81.8% patients 1 h after the procedure, in 86.3% after 1 week, in 93.3% after 4 weeks, in 85.7% after 12 weeks, and in 62.5% after 24 weeks. No major complications were encountered. Facet nerve block was found to be a simple, minimally invasive, and safe procedure. With meticulous patient selection, we achieved long-term success rates of over 60%. We conclude that this method represents an important alternative treatment for nonradicular back pain

Radiography of the bones and joints was performed in 133 psoriatic patients; osteoscintigraphy with 99m Tc-phosphate compounds was also performed in 42 of them. On the basis of x-ray findings 3 types of osteoarticular psoriasis were singled out: psoriatic polyarthritis, psoriatic polyarthrosis and psoriatic arthropathy. The most ample information on the type, activity and spreading of a pathological process in the bones and joints in psoriasis can be obtained from the combination of the x-ray and radionuclide methods

Radiological examination of the hands was performed in 41 patients with systemic sclerosis. Pathological changes were found in 39 patients. Eighteen patients had subcutaneous calcifications and 11 had atrophy of the finger pulps. Bone resorption of ungual tufts was found in 11 patients. Juxta-articular osteoporosis was seen in 9 patients and periarticular bone erosions in 8 patients indicating erosive arthropathy. Osteoarthritis and generalized osteoporosis were seen in 10 and 7 patients, respectively. Radiological examination of the hands is recommended during treatment. (Authors)

Prevalence and evolution of human parvoviruses

OpenAIRE

Norja, Päivi

2012-01-01

Parvoviruses are minute single-stranded DNA viruses that infect a wide range of mammalians and invertebrates. Human parvovirus B19 (B19V) was discovered in the 1970s and was soon found to cause several diseases, including erythema infectiosum, arthropathy, anemias, fetal hydrops, and fetal death. The B19V titer in blood is high during acute infection. After primary infection, B19V has been shown to persist in tissues of symptomatic and asymptomatic persons. Prior to the commencement of this w...

Prevalence of Parvovirus B19 and Parvovirus V9 DNA and Antibodies in Paired Bone Marrow and Serum Samples from Healthy Individuals

Heegaard, Erik D.; Petersen, Bodil Laub; Heilmann, Carsten J.; Hornsleth, Allan

2002-01-01

Parvovirus B19 (hereafter referred to as B19) exhibits a marked tropism to human bone marrow (BM), and infection may lead to erythema infectiosum, arthropathy, hydrops fetalis, and various hematologic disorders. Recently, a distinct parvovirus isolate termed V9 with an unknown clinical spectrum was discovered. In contrast to the many studies of B19 serology and viremia, valid information on the frequency of B19 or V9 DNA in the BM of healthy individuals is limited. To develop a reference valu...

We report a female with amyloid arthropathy of the hip joints. She was a 67-year-old woman who had been treated by hemodialysis for 22 years. She had demonstrated a 5-month history of continuous low-grade fever and pain in her left hip and she was finally unable to walk by herself. Findings on X-ray films and MRI of the hip joints suggested avascular necrosis in both femur heads. To palliate symptoms, bipolar surgery on the left hip joint was performed. Pathological examination of bone tissue specimen demonstrated that there was some , β 2 -microglobulin (β 2 -MG)-related amyloid accumulation in the femur head. Based on this clinical experience, we performed MRI screening for amyloid lesions of the hip joints in another 11 asymptomatic female patients undergoing hemodialysis for 20 years or more. Cystic lesions of the hip joints were observed in 8 patients, amyloid arthropathy in 2 patients, and fluid trapped in the joint in 1 patient. Patients with amyloidosis had significantly lower serum β 2 -MG levels than patients without amyloidosis (28.6 mg/L versus 41.4 mg/L; p=0.0339). Our findings show that dialysis-related amyloidosis of the hip joints is one of the potential and significant problems in female patients on long-term hemodialysis therapy. It may be important to screen for this pathological condition in long-term hemodialysis patients. (author)

In healthy joints, hyaline cartilage covering the joint surfaces of bones provides cushioning due to its unique mechanical properties. However, because of its limited regenerative capacity, age- and sports-related injuries to this tissue may lead to degenerative arthropathies, prompting researchers to investigate a variety of cell sources. We recently succeeded in isolating human cartilage progenitor cells from ear elastic cartilage. Human cartilage progenitor cells have high chondrogenic and proliferative potential to form elastic cartilage with long-term tissue maintenance. However, it is unknown whether ear-derived cartilage progenitor cells can be used to reconstruct hyaline cartilage, which has different mechanical and histological properties from elastic cartilage. In our efforts to develop foundational technologies for joint hyaline cartilage repair and reconstruction, we conducted this study to obtain an answer to this question. We created an experimental canine model of knee joint cartilage damage, transplanted ear-derived autologous cartilage progenitor cells. The reconstructed cartilage was rich in proteoglycans and showed unique histological characteristics similar to joint hyaline cartilage. In addition, mechanical properties of the reconstructed tissues were higher than those of ear cartilage and equal to those of joint hyaline cartilage. This study suggested that joint hyaline cartilage was reconstructed from ear-derived cartilage progenitor cells. It also demonstrated that ear-derived cartilage progenitor cells, which can be harvested by a minimally invasive method, would be useful for reconstructing joint hyaline cartilage in patients with degenerative arthropathies. © AlphaMed Press.

SAPHO syndrome-acronym for synovitis, acne, pustules, hyperostosis and osteitis, is a nosological entity including multiple affections with cutaneous and osteoarticular involvement. We report the case of a 59 years old female patient that consulted due to an acute sternal pain. After some months the patient showed a palm-plantar pustular exanthem, acne and fever. SAPHO syndrome was diagnosed based on a CT, an osseous gammagraphy and a biopsy of cutaneous lesions. The current actual tendency is to consider the SAPHO syndrome as a seronegative arthropathy with a similar pathophysiology to Reiter's syndrome. (author)

Computed tomography of sacro-iliac joints

Actual technologies to explore sacro-iliac joints are conventional radiography, computed tomography , scintigraphy and nuclear magnetic resonance imaging. Standards films are sufficient, except in beginning sacro-iliac septic inflammations where the computed tomography is superior. Two problems are generally posed for the radiologist, to differentiate a septic arthritis from a rheumatic pathology An other problem in diagnosis is to make the difference between a degenerative arthropathy (which does not need a further investigation) and an infectious rheumatic pathology where more exploration is necessary. 28 refs., 3 tabs., 13 figs

Conventional bone scintigraphy continues to be one of the most common diagnostic imaging requested by rheumatologist, despite development of new investigation modalities. Three (or two) phase bone scintigraphy, Single Photon Emission Computer Tomography have increased its value and provided new clinical roles. This review emphasizes through some practical clinical examples how to increase diagnostic value of the method, especially in the field of inflammatory diseases at early stages (rheumatoid arthritis and spondyl-arthropathy). Scintigraphy appears as a diagnostic tool, with requirements between clinical examination and radiographic examination-X Ray, computed tomography, ultrasonography, MRI. (author)

A Critical Review on Prosthetic Features Available for Reversed Total Shoulder Arthroplasty

Directory of Open Access Journals (Sweden)

Bart Middernacht

2016-01-01

Full Text Available Reversed total shoulder arthroplasty is a popular treatment in rotator cuff arthropathy and in displaced proximal humeral fractures in elderly. In 2016, 29 models of commercially available designs express this popularity. This study describes all the different design parameters available on the market. Prosthetic differences are found for the baseplate, glenosphere, polyethylene, and humeral component and these differences need to be weighed out carefully for each patient knowing that a gain in one mechanical parameter can balance the loss of another. Patient specific implants may help in the future.

Understanding causes of disability among elderly individuals is an important public health issue, particularly because of the increasing rate of disabled elderly individuals and the social costs in a rapidly aging society. Accordingly, we aimed to describe the diseases that precede disability and investigate the types of diseases that are related to severe disability among Japanese elderly individuals aged over 75 years. Using claim data from the latter-stage elderly healthcare system and long-term care insurance system, we identified 76,265 elderly individuals over 75 years old who did not qualify as disabled on April 1, 2011. Among them, 3,715 elderly individuals who had been newly qualified as disabled between April 1, 2011 and March 31, 2012 were selected. Disease codes from the medical claim data in the 6 months prior to disability were collected. All descriptions were developed separately for six groups divided by gender and disability level (low, middle, and high). The results of the ordinal logistic analysis including sex and age revealed that men tended to have significantly higher levels of disability (β = 0.417, p disability level groups. In low-level disability groups, cancer in men (12.8%) and arthropathy and fracture in women (11.9% and 13.5%, respectively) were as common as cerebrovascular disorder (12.2% and 9.7%, in men and women, respectively). Stroke was the most common disease for all genders and disability levels. The diseases preceding low-level disability differed by gender. This study demonstrated the need to consider arthropathy and fracture as well as CVD in order to prevent disability.

Superior migration of the humeral head after massive rotator cuff tear (mRCT) is thought to lead to cuff tear arthropathy. Previous biomechanical studies have demonstrated the ability of the pectoralis major and latissimus dorsi (PM/LD) muscles to resist this migration. This study examined the role of PM/LD muscles on glenohumeral joint forces and acromiohumeral contact pressures in a mRCT model. Six cadaveric shoulders were tested using a custom shoulder-testing system. Muscle insertions of the rotator cuff, deltoid, and PM/LD were preserved and used for muscle loading. Specimens were tested in 3 different humeral rotation positions at 0° abduction and 2 rotation positions at 60° abduction. Testing was performed for intact specimens, after supraspinatus removal, and after supraspinatus/infraspinatus/teres minor removal. PM/LD were loaded or unloaded to determine their effect. Humeral head kinematics, glenohumeral joint forces, and acromiohumeral contact area and pressure were measured. For the mRCT condition at 0° abduction, unloading the PM/LD resulted in superior shift of the humeral head. Acromiohumeral contact pressures were undetectable when the PM/LD were loaded but increased significantly after PM/LD unloading. After mRCT, superior joint forces were increased and compressive forces were decreased compared with intact; loading the PM/LD resolved these abnormal forces in some testing conditions. In mRCT, the PM and LD muscles are effective in improving glenohumeral kinematics and reducing acromiohumeral pressures. Strengthening or neuromuscular training of this musculature, or both, may delay the progression to cuff tear arthropathy. Published by Mosby, Inc.

Identification of trabecular excrescences, novel microanatomical structures, present in bone in osteoarthropathies

Directory of Open Access Journals (Sweden)

AM Taylor

2012-04-01

Full Text Available It is widely held that bone architecture is finely regulated in accordance with homeostatic requirements. Aberrant remodelling (hyperdensification and/or cyst formation in the immediately subchondral region has previously been described in bone underlying cartilage in arthropathies. The present study examined the trabecular architecture of samples of bone, initially in the severe osteoarthropathy of alkaptonuria, but subsequently in osteoarthritis using a combination of light microscopy, 3D scanning electron microscopy and quantitative backscattered electron scanning electron microscopy. We report an extraordinary and previously unrecognised bone phenotype in both disorders, including novel microanatomical structures. The underlying subchondral trabecular bone contained idiosyncratic architecture. Trabecular surfaces had numerous outgrowths that we have termed "trabecular excrescences", of which three distinct types were recognised. The first type arose from incomplete resorption of branching secondary trabeculae arising from the deposition of immature (woven bone in prior marrow space. These were characterised by very deeply scalloped surfaces and rugged edges. The second type had arisen in a similar way but been smoothed over by new bone deposition. The third type, which resembled coarse stucco, probably arises from resting surfaces that had been focally reactivated. These were poorly integrated with the prior trabecular wall. We propose that these distinctive microanatomical structures are indicative of abnormal osteoclast/osteoblast modelling in osteoarthropathies, possibly secondary to altered mechanical loading or other aberrant signalling. Identification of the mechanisms underlying the formation of trabecular excrescences will contribute to a better understanding of the role of aberrant bone remodelling in arthropathies and development of new therapeutic strategies.

Full Text Available Background: Gout is the most common form of crystal arthropathy. Monoarthritis affecting the first metatarsophalangeal joint is the common initial presentation. Bilateral olecranon bursitis is a rare presentation of gout. Aim of the work: To describe the clinical features of bilateral olecranon bursitis as an initial presentation of gout. Case report: A 62-year old male patient presented to the rheumatology clinic , Adnan Menderes University with sudden bilateral elbow pain and swelling for three months . Swellings gradually increased to the size of a golf ball with minimal restriction in the elbow extension (170°. He didn’t have arthritis in the elbows. The patient had medical history of heart failure and chronic obstructive pulmonary disease and medications received included acetylsalicylic acid and diuretics. Blood tests revealed elevated serum uric acid (12.6 mg/dL, with normal renal function tests, erythrocyte sedimentation rate (ESR 43 mm/h and C-reactive protein (CRP 8.8 mg/L. Rheumatoid factor and hepatitis markers were negative. Diagnostic bursal aspiration excluded septic bursitis and under polarized microscopy monosodium urate (MSU crystals were identified with typical negative birefringence. A diagnosis of gout was established. ESR and CRP were normalized after diclofenac potassium (100 mg and colchicine (1.5 mg. Allopurinol 300 mg was added when his joint pain was relieved. Conclusion: This is the first gout case initially presenting with bilateral olecranon bursitis. Bursal fluid analysis is important in such atypical presentation to look for MSU crystals and establish a diagnosis. Keywords: Olecranon bursitis, Gout, Crystal arthropathy, Monosodium urate

Focal destruction of the postero-lateral distal femoral epiphysis was present on radiographs in two children with spina bifida and objective lower limb sensory loss. Each patient presented with painless swelling of the knee. In one patient the epiphysis showed sclerosis and fragmentation associated with a defect. In the second patient the destructive change was the dominant radiographic abnormality and simulated bone tumor. Computed tomography in this patient showed a bone fragment occupying the defect suggesting epiphyseal fracture. The lesions in each patient were believed to be traumatic in origin and to represent a stage in the development toward neuropathic arthropathy.

The technetium phosphate bone scans of 106 children with suspected septic arthritis were reviewed to determine whether the bone scan can accurately differentiate septic from nonseptic arthropathy. Only 13% of children with proved septic arthritis had correct blind scan interpretation. The clinically adjusted interpretation did not identify septic arthritis in 30%. Septic arthritis was incorrectly identified in 32% of children with no evidence of septic arthritis. No statistically significant differences were noted between the scan findings in the septic and nonseptic groups and no scan findings correlated specifically with the presence or absence of joint sepsis

Neonatal onset multisystem inflammatory disease is a rare disorder first described by Lorber in 1973. An additional 29 cases have been recorded. Two patients are described here, one with a 17 year follow-up. The typical features are a rash, fever, adenopathy, hepatosplenomegaly, and a severe, deforming arthropathy predominantly affecting large joints. The most striking feature is the onset in the neonatal period. Other associated features include inflammation, chronic meningitis, anemia, and persistent leukocytosis. Most, if not all, patients develop bizarre epiphyseal radiographic findings that are virtually pathognomonic. This disease is distinct from Still disease. (orig.).

Early detection of alkaptonuria

Full Text Available Alkaptonuria is a rare disorder of metabolism characterized by deficiency of homogentisic acid oxidase. This leads to the characteristic features like darkening of urine, ochronosis and arthropathy. Darkening of urine is one of the first symptoms noticed by the parents of the child suffering from this disorder. Ochronosis is seen in various organs like eyes, skin, tendons and joints. A case of 10 year old boy is reported who was brought to this clinic with the presenting complaint of bluish discoloration of sclerae. This discoloration led to eliciting positive history of dark urine off and on. Further investigations confirmed alkaptonuria.

The cervical spine may be specifically involved in crystal-associated arthropathies. In this article, we focus on the three common crystals and diseases: hydroxyapatite crystal deposition disease, calcium pyrophosphate dihydrate (CPPD) deposition disease, and monosodium urate crystals (gout). The cervical involvement in crystal-associated diseases may provoke a misleading clinical presentation with acute neck pain, fever, or neurological symptoms. Imaging allows an accurate diagnosis in typical cases with calcific deposits and destructive lesions of the discs and joints. Most of the cases are related to CPPD or hydroxyapatite crystal deposition; gout is much less common. (orig.)

Musculoskeletal manifestations in chronic renal insufficiency are caused by complex bone metabolism alterations, now described under the umbrella term of chronic kidney disease mineral- and bone-related disorder (CKD-MBD), as well as iatrogenic processes related to renal replacement treatment. Radiological imaging remains the mainstay of disease assessment. This review aims to illustrate the radiological features of CKD-MBD, such as secondary hyperparathyroidism, osteomalacia, adynamic bone disease, soft-tissue calcifications; as well as features associated with renal replacement therapy, such as aluminium toxicity, secondary amyloidosis, destructive spondyloarthropathy, haemodialysis-related erosive arthropathy, tendon rupture, osteonecrosis, and infection

1977-06-01

A prospective study of bone scintigraphic findings has been carried out in 63 patients, firmly diagnosed as having ankylosing spondylitis. In addition to abnormal uptake of the radiotracer at the sacroiliac joints, a peripheral arthropathy has been a common finding, particularly in the proximal joints, occurring in up to 50% of patients. Increased uptake of radiotracer in the spine has also been found both diffusely and focally. Focal increases have been noted at the apophyseal joints in 40% of patients and in three patients with a sterile intervertebral diskitis, an unusual complication of this disease only diagnosed in two patients after bone scintigraphy.

Abnormal morphologic findings in imaging were thought to explain the etiology of low back pain (LBP). However, it is now known that variety of morphologic abnormalities is noted even in asymptomatic individuals. Single photon emission computed tomography/computed tomography (SPECT/CT) could be used to differentiate incidental findings from clinically significant findings. This study was performed to define the SPECT/CT patterns in patients with LBP and to correlate these with clinical and magnetic resonance imaging (MRI) findings. Thirty adult patients with LBP of duration 3 months or more were prospectively evaluated in this study. Patients with known or suspected malignancy, trauma or infectious processes were excluded. A detailed history of sensory and motor symptoms and neurologic examination was performed. All the patients were subjected to MRI and bone scintigraphy with hybrid SPECT/CT of the lumbo-sacral spine within 1 month of each other. The patients were classified into those with and without neurologic symptoms, activity limitation. The findings of clinical examination and imaging were compared. MRI and SPECT/CT findings were also compared. Thirty patients (18 men and 12 women; mean age 38 years; range 17-64 years) were eligible for the study. Clinically, 14 of 30 (46%) had neurologic signs and or symptoms. Six of the 30 patients (20%) had positive straight leg raising test (SLRT). Twenty-two of the 30 patients (73%) had SPECT abnormality. Most frequent SPECT/CT abnormality was tracer uptake in the anterior part of vertebral body with osteophytes/sclerotic changes. Significant positive agreement was noted between this finding and MRI evidence of degenerative disc disease. Only 13% of patients had more than one abnormality in SPECT. All 30 patients had MRI abnormalities. The most frequent abnormality was degenerative disc disease and facet joint arthropathy. MRI showed single intervertebral disc abnormality in 36% of the patients and more than one

The main clinical manifestations of hemophilia are muscle and joint bleeding. Recurrent bleeding leads to a degenerative process known as hemophilic arthropathy. The development of inhibitors (antibodies against FVIII/FIX concentrates) is the main complication in the treatment of hemophilia. The objective was to assess the safety and efficacy of manual therapy treatment in a patient with hemophilia and inhibitor. A 26-year-old patient with hemophilia B and inhibitor received physiotherapy treatment based on manual therapy for 3 months, with a frequency of 2 sessions per week. The joint status was evaluated using the Hemophilia Joint Health Score; pain was assessed with the Visual Analog Scale; and the range of movement was evaluated using a universal goniometer. The patient developed no joint bleeding in the knees or ankles as a result of the physiotherapy treatment. Following treatment, improvements were noted in the range of movement of knees and ankles, the perception of pain in both knees, and ankle functionality. Until now, manual therapy using joint traction was contraindicated in patients with hemophilia and inhibitor, as it was feared to cause possible joint bleeding. This is the first case study to address the safety and efficacy of manual therapy in a patient with hemophilia and an inhibitor. The results of this study may help to establish which manual therapy treatments are indicated in patients with hemophilic arthropathy and inhibitors. Thus, a physiotherapy program based on manual therapy may be safe in patients with hemophilia and inhibitor and such therapy may improve joint condition, pain, and joint range of motion in patients with hemophilia and inhibitor. Randomized clinical trials are needed to confirm the results of this case study.

Purpose. Ochronotic arthropathy is the articular manifestation of alkaptonuria, a rare hereditary metabolic disease that leads to the deposition of homogentisinic acid particularly in the joints where it causes articular degeneration and inflammation. We studied the radiological patterns of the disorder using both traditional X rays both MRI and comparing the results obtained with the two techniques. Materials and methods. The study included five patients (4 males, 1 female, mean age 51 years); we studied the most frequently affected sites, the knee, the shoulder and the spine. As regards the conventional study we used a radiographic score which considered the state of the articular space and the presence of calcifications. MRI of the peripheral joints was performed on the most symptomatic site or, if asymptomatic, on the most severely affected site as established by radiography; in all cases T1- and T2 weighted sequences in the axial, sagittal and coronal planes were acquired. Results. Both the X-ray and MRI study revealed the typical alterations of ochronosis in the cases with a known diagnosis: articular space narrowing up to osseous ankylosis, calcifications, osteophytosis, reactive sclerosis of the articular surfaces; MRI was how evermore accurate. in identifying the alterations and revealing lesions not visible at conventional radiology, such as ligament lesions. In the case of newly diagnosed ochronotic arthropathy MRI proved valuable for its ability to detect alterations that are poorly appreciable at conventional radiology. Conclusions. Modern diagnostic imaging, above all MRI, allowed to identify the peculiar characteristic features of ochronosis and is fundamental both for the diagnosis and for differentiating ochronosis from other articular disorders [it

Magnetic resonance imaging (MRI) is considered to be the best non-invasive procedure for the evaluation of rotator cuff (RC) tendon tears. Burkhart's classification is a geometric classification of full-thickness RC tears on MRI. To correlate MRI and arthroscopic geometric full-thickness RC tears according to the Burkhart's classification with pre- and postoperative clinical findings. Patients who underwent arthroscopic RC repair between 2006 and 2010 were retrospectively evaluated. Preoperative MRI and arthroscopic surgical reports were reviewed for tear geometry (Burkhart's) by three (1 radiologist, 2 surgeons) and two (surgeons) readers. MRIs were also evaluated for tear size and change of tear size in successive sagittal sections and for muscle mass and fatty infiltration. Clinical examinations were performed preoperatively and at least 12 months afterwards. Postoperative function questionnaires were filled in by the patients. Forty-six patients (35 men, 11 women; mean age, 57 years; range, 41-72 years) were evaluated. Tears depicted on MRIs were classified as crescent in 11 patients (24%), longitudinal in three (6.5%), massive contracted in 29 (63%), and cuff arthropathy in three (6.5%). Muscle changes were noted almost exclusively in patients with massive tears and cuff arthropathy (16/32 patients, P = 0.013). MRIs and arthroscopic geometric classifications were in close agreement. Tear type did not correlate with pre- and postoperative physical examination or with postoperative clinical questionnaires scores. Geometric RC tear characterizations on preoperative MRIs were closely associated with arthroscopic findings. Postoperative results were not affected by the geometric pattern of the tears. © The Foundation Acta Radiologica 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Full Text Available This study was designed to analyse the clinical and epidemiological data from human parvovirus B19 cases in a six-year study of rash diseases conduct in an urban area in Brazil (Niterói city area, State of Rio de Janeiro. A total of 673 patients with acute rash diseases were seen at two primary health care units and at a general hospital. A clotted blood sample was collected from all subjects at the time of consultation. Forty-nine per cent (330 cases of the patients were negative for dengue, rubella and measles IgM or for low avidity IgG to HHV-6. Of these 330, 105 (31.8% were identified as IgM positive to parvovirus B19 by using an antibody capture EIA. During the study period, three distinct peaks of parvovirus infection were detected, suggesting that the disease appears to cycle in approximately 4-5 years. B19 infection was characterized by variable combinations of fever, flu-like symptoms, arthropathy, and gastrointestinal symptoms. Frequency of fever and arthropathy was substantially higher in adults, 75% [chi2 (1 D.F. = 11.39, p = 0.0007] and 62.5% [chi2 (1 D.F. = 29.89, p = 0.0000], respectively. "Slapped-cheek" appearance and reticular or lace-like rash were seen in only 30.1% of the children. No adult presented this typical rash. The lack of the typical rash pattern in a large proportion of parvovirus B19 and the similarity of clinical manifestations to other rash diseases, specially to rubella, highlight the difficulty of diagnosing B19 infection on clinical grounds alone.

2014-12-01

Full Text Available Chikungunya virus (CHIKV and Mayaro virus (MAYV are emergent arthropod-borne viruses that produce outbreaks of acute febrile illness with arthropathy. Despite their different continental origins, CHIKV and MAYV are closely related and are components of the Semliki Forest Complex of the Alphavirus (Togaviridae. MAYV and, more recently, CHIKV, which are both transmitted by Aedes mosquitoes, have resulted in severe public health problems in the Americas, including Brazil. In this review, we present aspects of the pathogenesis, clinical presentation and treatment of febrile illnesses produced by CHIKV and MAYV. We also discuss the epidemiological aspects and effects related to the prophylaxis of infections by both viruses.

Full Text Available Hemochromatosis is the most common form of iron overload disease. Iron builds up in the body’s organs and damages them. Hemochromatosis is presented with arthropathy, cirrhosis of the liver, melanoderma, heart failure, diabetes mellitus and other endocrine deficiencies. There are two type of this disease. Primary hemochromatosis is known as an inherited disease. Herediter hemochromatosis is caused by the mutations of HFE gene. The most common mutations are H63D (Histidine- Aspartat and C282Y (Cysteine-Tyrosine on the gene. Secondary hemochromatosis is caused by anemia, alcoholism, and some of the other disorders.

2014-01-01

Juvenile idiopathic arthritis (JIA) is the most common arthropathy of childhood and adolescence. This term encompasses a group of chronic systemic inflammatory diseases of the connective tissue which cause arthritis in patients under 16 years of age lasting at least 6 weeks. The authors presented the characteristic features of physiotherapy based on functional examination results on the basis of two cases of girls with pauciarticular JIA treated according to an established pharmacological regimen. Physiotherapy should be introduced at an early stage of the disease. Kinesiotherapy preceded by history-taking and a functional examination of the patient, has to focus on both primary and secondary joint lesions.

Scapholunate advanced collapse

Chen, C.; Haller, J.; Resnick, D.

1989-01-01

Scapholunate advanced collapse 9SLAC) is a pattern of wrist malalignment (characterized mainly by radiocarpal abnormalities) that has been attributed to osteoarthritis. In order to determine the frequency of SLAC in calcium pyrophosphate dihydrate (CPPD) disease, the authors have reviewed wrist radiographs in 190 cases of this disorder. Forty-two (22%) of these cases reveal wrist abnormalities typical of SLAC. Associated findings include bilateral alterations (63%), abnormal calcification (70%), scapholunate dissociation (70%), and additional compartmental arthropathies. The authors' results confirm that CPPD crystal deposition disease is a major cause of SLAC. They believe, therefore, that this pattern of malalignment is not specific for posttraumatic or spontaneous osteoarthritis of the wrist

The skeletal changes of progressive systemic scleroderma (PSS), of exclusive Raynaud phenomenon and of circumscript scleroderma in a gamma camera scintigraph

1987-01-01

The bases of this study are the skeletal scintigraphs of altogether 34 patients with the three forms of scleroderma mentioned in the title. The PSS shows a polytropic, symmetric distribution pattern, the exclusive Raynaud's phenomenon shows a basic skeleton which is unchanged in contrast to circumscript scleroderma, with which also the larger joints are relatively more frequently attacked than the little ones. As a result of high sensitivity skeletal scintiscanning makes possible an early recognition of osseous changes and is there with superior to X-radiology and should then see an increased use for the clarification of the diagnosis of arthropathy in scleroderma.

Thakur, Sameer; Markman, Phuong; Cullen, Hugh

2013-10-01

Alkaptonuria is a rare inherited disorder of tyrosine metabolism, which results in deposition of homogentisic acid in the connective tissues. The accumulation of homogentisic acid in connective tissue causes the syndrome known as ochronosis, which is typically manifested by skin pigmentation, degenerative arthropathy and discolouration of urine. Cardiovascular involvement is a much less common complication of alkaptonuria but poses a greater risk to the patient's health. We present the case of a 65 year-old man with aortic stenosis and a previous diagnosis of alkaptonuria who underwent successful aortic valve replacement with a mechanical prosthesis.

What lessons can history teach us about the Charcot foot?

Science.gov (United States)

Sanders, Lee J

2008-01-01

Regrettably, physicians today receive very little instruction in the history of medicine. Most health care providers have a very limited, contemporary knowledge of the condition that we know of as the Charcot foot. Yet, historical concepts of the pathogenesis and natural history of this condition provide us with important lessons that enhance our understanding, recognition, and management of this rare but debilitating neurogenic arthropathy. It is my belief that knowledge of the history of medicine provides us with a better understanding of present-day issues and clearer vision as we look to the future. This article describes some of the important lessons learned from the history of the Charcot foot.

A 51 year old man with severe degenerative joint disease, short stature, barrel chest deformity, platyspondyly, a narrow pelvis, small iliac bones, dysplastic femoral heads and necks, notching of the patellae and flattening of the femoral intercondylar notches has been described as an example of Spondyloepiphyseal dysplasia tarda SDT. The entity was discussed in detail. The notching of the patellae has not been reported in association with SDT to the authors' knowledge. Characteristic features of SDT allow it to be differentiated from other arthropathies and dysplasias and these distinctions have been emphasized in the discussion. The diagnosis in this case can only be considered presumptively proved. (orig./MG)

A prospective study of bone scintigraphic findings has been carried out in 63 patients, firmly diagnosed as having ankylosing spondylitis. In addition to abnormal uptake of the radiotracer at the sacroiliac joints, a peripheral arthropathy has been a common finding, particularly in the proximal joints, occurring in up to 50 percent of patients. Increased uptake of radiotracer in the spine has also been found both diffusely and focally. Focal increases have been noted at the apophyseal joints in 40 percent of patients and in three patients with a sterile intervertebral diskitis, an unusual complication of this disease only diagnosed in two patients after bone scintigraphy

Leprosy, like other neuropathic disorders, can involve the skeleton, affecting both bone and joints, especially those segments that have to withstand weight. To asses the osteoarticular involvement of the wrist and hand in 58 patients with leprosy. The radiographic images of wrist and hand of 58 patients with Hansen's disease were reviewed. The entire spectrum of specific and nonspecific bone lesions described in the literature is presented. Despite the fact that the upper limbs do not have to withstand the weight that the feet and ankles do, radiographic images show that gripping and other common motions can also produce lesions compatible with those of neuropathic arthropathy.

Back and joint pain are the most common extraintestinal symptoms reported by patients with inflammatory bowel disease (IBD). We assessed the impact of back/joint pain, illness perceptions, and coping on quality of life (QOL) and work productivity in patients with IBD. Our cohort included 155 IBD patients with and 100 without arthropathy. Arthropathy was defined as daily back pain for ≥3 months and/or peripheral joint pain and/or joint swelling over the last year. At baseline and at 12 months, patients completed questionnaires on the extent of back/joint pain, IBD disease activity, illness perceptions, coping, QOL, and work productivity. The impact of back/joint pain, illness perceptions and coping on QOL and work productivity was determined, using linear mixed models. In total, 204 IBD patients (72% Crohn's disease, 40% male, mean age 44 ± 14 years) completed questionnaires at both time points. At both time points, IBD patients with back/joint pain reported a significantly lower QOL and work productivity compared with IBD patients without back/joint pain. Predictors of low QOL were back/joint pain (β = -1.04, 95% confidence interval [CI] -1.40, -0.68), stronger beliefs about the illness consequences (β = -0.39, 95% CI -0.59, -0.18) and emotional impact of IBD (β = -0.47, 95% CI -0.66, -0.28), and the coping strategy 'decreasing activity' (β = -0.26, 95% CI -0.48, -0.03). Predictors of work productivity were back/joint pain (β = 0.22, 95% CI 0.07, 0.37) and illness consequences (β = 0.14, 95% CI 0.06, 0.22). Back/joint pain, illness perceptions, and coping are significant predictors of QOL and work productivity, after controlling for disease activity.

A rare cause of osteonecrosis

Directory of Open Access Journals (Sweden)

Paolo Agostinis

2012-01-01

Full Text Available IntroductionHereditary hemochromatosis (HH is an autosomal recessive disorder caused by mutations in the HFE gene, which increase intestinal iron absorption. The prevalence of C282Y homozygosity, which causes the disorder, is 0.5% in Caucasian populations. The clinical manifestations are related to excess iron in the tissues, especially the liver, heart, pancreas, pituitary, and skin. They include fatigue, loss of libido or impotence in males, liver disease, skin pigmentation, diabetes mellitus, cardiac enlargement—with or without heart failure, and conduction defects. The classic triad of cirrhosis, diabetes mellitus, and skin pigmentation (“bronze diabetes” results from a combination of iron deposits and melanin. It occurs late in the disease, when the total body iron content is more than five times the normal value, about 20 grams. Left untreated, approximately half of all patients with HH eventually develop arthralgia or arthropathy. Chondrocalcinosis, chronic pseudo-osteoarthritis, and osteoporosis are the major rheumatic manifestations of HH. The cause of the arthropathy is still unknown. Iron deposits within joints may trigger a number of pathologic events, such as free radical generation and crystal deposition, which stimulate immune complex formation and inflammation.Materials and methodsWe describe the case of a 48-year-old male suffering from chronic bilateral ankle pain.ResultsThe work-up revealed osteonecrosis of ankle. The patient also presented high plasma ferritin levels and homozygosity for the C282Y mutation. Other than HH, which was confirmed by liver biopsy, the patient had no other risk factors for osteonecrosis.DiscussionHH represents a rare cause of osteonecrosis, and there are no prior reports of aseptic osteonecrosis of the ankle in a patient with this disease. The pathogenetic mechanism remains unknown.

Nuclear medicine techniques in the assessment of alkaptonuria.

Vinjamuri, Sobhan; Ramesh, Chandakacharla N; Jarvis, Jonathan; Gallagher, Jim A; Ranganath, Lakshminarayana L

2011-10-01

Alkaptonuria is a rare autosomal recessive disorder due to a lack of the enzyme homogentisate dioxygenase, leading to ochronosis, a process of accumulation of a melanin-like polymer of homogentisic acid in cartilage and other collagenous structures. Patients develop severe osteoarthropathy that resembles osteoarthritis. Although the diagnosis of alkaptonuria is not particularly challenging in view of the blue-black discolouration of visible connective tissue and the presence of homogentisic acid in urine, the natural history of alkaptonuria remains poorly understood. Patients would benefit immensely from an objective assessment of their disease status and from a clearer understanding of the pathophysiology and associated physical changes. Isotope bone scans, which are commonly used to identify the extent of involvement of bones in cancerous processes, have also been increasingly used for characterizing the extent of arthropathy in conditions such as osteoarthritis and rheumatoid arthritis. Semiquantitative scores based on the extent of involvement of joints have been used to describe the involvement of large joints in the context of symptomatic treatment for osteoarthritis. A similar semiquantitative isotope bone scan score depending on the involvement of the number of large joints in patients with alkaptonuria can be formulated and validated in a suitable cohort of patients. Bone densitometry measurement using dual-energy X-ray absorptiometry scanning is an internationally accepted tool to assess the risk and extent of osteoporosis, and is increasingly used to assess the additional fracture risk in patients with arthropathy. We believe that, currently, nuclear medicine techniques can provide useful information, which can be incorporated into disease severity scores for alkaptonuria. Once the biological basis for alkaptonuria is better understood, it is feasible that nuclear medicine techniques of even greater sensitivity and specificity can be developed, thereby

With the introduction of new biologics such as anti-TNF-alpha antibodies and other therapies in the treatment of inflammatory arthritis, capable of halting joint destruction and functional disability, there are new pressures on diagnostic and prognostic imaging. Early demonstration of pre-erosive inflammatory features and monitoring of the long-term effects of treatment are becoming increasingly important. Early detection of synovitis offers advantages in terms of allowing early instigation of therapy and may allow the identification of those patients displaying more aggressive disease who might benefit from early intervention with expensive DMARD therapy. Advanced imaging techniques such as ultrasound (US) and magnetic resonance imaging (MRI) have focussed on the demonstration and quantification of synovitis and allow early diagnosis of inflammatory arthropathies such as rheumatoid arthritis (RA) and psoriatic arthritis (PsA). Synovitis represents a potential surrogate measure of disease activity that can be monitored using either MRI or US; the techniques have, generally, focused on monitoring synovial volume or quality as assessed by its vascularity. However to achieve these goals, standardisation and validation of US and MRI are required to ensure accurate diagnosis, reproducibility and reliability. Each modality has different strengths and weaknesses and levels of validation. This article aims to increase the awareness of radiologists and rheumatologists about this field and to encourage them to participate and contribute to the ongoing development of these modalities. Without this collaboration, it is unlikely that these modalities will reach their full potential in the field of rheumatological imaging. This review is in two parts. The first part addresses the role of US and colour or power Doppler sonography (PDUS) in the detection and monitoring of synovitis in inflammatory arthropathies. The second part will look at advanced MR imaging and Dynamic contrast

"Changes in cartilage of rats after treatment with Quinolone and in Magnesium-deficient diet "

2002-07-01

Full Text Available Ultrastructural changes in immature articular carilage were studied after treatment of 5-weeks-old rats with ofloxacin, a fluoroquinolone, and in magnesium deficiency.We concluded that quinolone-induced arthropathy is probably due to chelation of functionally available magnesium in joint cartilage as magnesium deficiency in joint cartilage could impair chondrocyte-matrix- interaction which is mediated by cation-dependent integrin-receptors of the β1-subfamily. With immuno-histochemical methods using monoclonal and polyclonal antibodies we showed that B1 integrins were expressed in rat joint cartilage. Joint cartilage lesions were detected in ofloxacin-treated and magnesium-deficient rats. Lesions were more pronounced in the quinolone-treated group. Expression of several integrins was reduced in the vicinity of lesions after oral treatment with 2×600 mg ofloxacin/kg body wt for one day. Gross-structural lesions (e.g. cleft formation, unmasked collagen fibres in magnesium deficient rats were very similar but changes in intergrin expression were less pronounced. Alterations observed on the ultrastructural level showed striking similarities in magnesium-deficient rats and in rats treated with single doses of 600 mg ofloxacin per kg body wt.Typical observation were: bundle shaped, electron-dense aggregates on the surface and in the cytoplasm of chondrocytes, detachement of the cell membrance from the matrix and necrotic chondrocytes, reduced synthesis and/or reduced of extracellular matrix and swelling of cell organelles such as mitochondria.The results of this study confirm our previously reported finding that quinolone-induced arthropathy probably is caued by a reduction of functionally available magnesium (ionized Mg2+ in cartilage. Furthermore, they provide a basis for aimed studies with human cartilage samples from quinolone-treated patients which might be available postmortal or after hip replacement surgery

Total Knee Arthroplasty in Alkaptonuric Ochronosis: the First Case Report in Thailand and Literature Review

Directory of Open Access Journals (Sweden)

Witchuree Wejjakul

2016-09-01

Full Text Available Ochronosis is a musculoskeletal manifestation found in alkaptonuria which is a rare autosomal reces- sive disorder caused by the deficiency of homogentistic acid oxidase enzyme. This leads to accumulation and deposition of homogentistic acid (HGA pigments in skin, sclera, tendon, ligament and cartilage. Ochronosis is asymptomatic until ochronotic arthropathy occurs. We reported a case of 64-year female presented with advanced degenerative changes in the knee, hip, shoulder and lumbo-sacral spine. The operative findings during total knee arthroplasty showed bluish-black discoloration of the entire articular surface. Her urine HGA level was extremely high. Histopathological exam confirmed ochronosis. The literature, differential diagnosis and management of this rare condition are reviewed.

Quadriceps weakness seems to be a hallmark in adult persons with severe haemophilia (PWH). The purpose of this study was to compare PWH and non-haemophilic controls in different age stages with reference to joint status and quadriceps strength. Further aims were to examine the extent of strength-specific inter-extremity-difference (IED) and the prevalence of abnormal IED (AIED). A total of 106 adults with severe haemophilia (H) and 80 controls (C) had undergone an orthopaedic examination for classification of knee and ankle status using the WFH score. Quadriceps strength was evaluated unilaterally as well as bilaterally with a knee extensor device. Each group was divided into four age-related subgroups (HA/CA: 18-29, HB/CB: 30-39, HC/CC: 40-49, HD/CD: 50-70; in years). H presented a worse knee and ankle status than C indicated by higher WFH scores (P age-matched subgroups only HB showed higher knee scores than CB (P age-matched controls (P age in H. We discovered an AIED in 35% of H. These findings highlight the importance for the early implementation of preventive and rehabilitative muscle training programmes in the comprehensive treatment of PWH. © 2012 Blackwell Publishing Ltd.

Haemophiliacs who have had to keep a physically inactive lifestyle due to bleeding during childhood are likely to have little motivation for exercise. The purpose of this study is to clarify the effectiveness of the self-monitoring of home exercise for haemophiliacs. A randomized controlled trial was conducted with intervention over 8 weeks at four hospitals in Japan. Subjects included 32 male outpatients aged 26-64 years without an inhibitor who were randomly allocated to a self-monitoring group and a control group. Individual exercise guidance with physical activity for improvement of their knee functions was given to both groups. The self-monitoring materials included an activity monitor and a feedback system so that the self-monitoring group could send feedback via the Internet and cellular phone. The self-monitoring was performed by checking exercise adherence and physical activity levels, bleeding history and injection of a coagulation factor. Both groups showed significant improvements in exercise adherence (P self-efficacy (P self-monitoring group compared with those in the control group. No increase in bleeding frequency and pain scale was noted. The self-monitoring of home exercise for haemophilic patients is useful for the improvement of exercise adherence, self-efficacy and knee extension strength. © 2014 John Wiley & Sons Ltd.

Synoviorthesis with colloidal /sup 32/P chromic phosphate for hemophilic arthropathy: clinical follow-up

Rivard, G.E.; Girard, M.; Lamarre, C.; Jutras, M.; Danais, S.; Guay, J.P.; Belanger, R.D.

1985-11-01

Thirty-one synoviortheses were performed in 22 joints of 14 hemophilic patients (aged 12 to 28 years) with chronic synovitis and for whom conventional treatments were considered ineffective. Except for patients with inhibitors, conventional treatments included three to six months of adequate prophylactic therapy with the missing coagulation factors, intensive physiotherapy and, when indicated, antiinflammatory agents and orthosis. Colloidal /sup 32/P chromic phosphate was injected intraarticularly in doses of 1.0 mCi for knees and of 0.5 mCi for the other joints. Time of follow-up ranged from two to five years. Frequency and importance of bleeding decreased in all patients. Effect on range of motion was best in knees. In elbows, flexion-extension was improved in four cases, unchanged in five and decreased in one; pronation-supination was decreased in four cases. The results of 13 synoviortheses in four hemophilic patients with high titer factor VIII inhibitors were comparable to those in hemophiliacs with no inhibitors. However, in three of the four patients synoviorthesis had to be repeated after two to four years for recurrence of synovitis. Extraarticular escape of radioactivity was monitored 62 times for 17 synoviortheses in 12 patients; extraarticular counts never exceeded 4% of the intraarticular counts. Chromosome aberrations were found not to be increased after treatment in the seven patients in whom adequate analysis could be done.

Full Text Available Alkaptonuria is a rare metabolic disease caused by a partial or total deficiency of homogentisic acid oxidase, which results in excess homogentisic acid (HGA levels. Homogentisic acid and its oxidation products can accumulate in hyaline cartilage, tendons, and ligaments. A 55-year-old male was admitted complaining of worsening chronic pain in his left knee. A radiographic evaluation showed tricompartmental end- stage osteoarthritis. A cemented total knee replacement was performed. At the 10-year follow-up, he had returned to full activity, had no knee pain, and was very satisfied with the outcome. No abnormality was observed in the femoral, tibial, or patellar components on radiography. We believe that total knee replacement is a good option in a patient with marked degenerative arthritis secondary to ochronotic arthritis.

Possible alendronate-induced polyarticular synovitis

Directory of Open Access Journals (Sweden)

K Gökkus

2016-01-01

The patient had no evidence of rheumatoid arthritis, pyrophosphate arthropathy, or seronegative/seropositive arthritis. Our main aim in this study is to highlight the potential adverse effects of alendronate and to warn orthopedic surgeons about the possibility of such a side effect that might lead orthopedic surgeons to administer wrong and unnecessary treatments like arthrocentesis. The withdrawal of alendronate is found to be the treatment of choice. Alendronate should be considered as a possible cause of synovitis or polyarthritis in patients treated with this agent in the absence of any other pathology. An association between alendronate and synovitis has rarely been described in the literature. We present a patient who developed polyarticular synovitis after treatment with alendronate and responded to its withdrawal.

An innovative outcome-based care and procurement model of hemophilia management.

Gringeri, Alessandro; Doralt, Jennifer; Valentino, Leonard A; Crea, Roberto; Reininger, Armin J

2016-06-01

Hemophilia is a rare bleeding disorder associated with spontaneous and post-traumatic bleeding. Each hemophilia patient requires a personalized approach to episodic or prophylactic treatment, but self-management can be challenging for patients, and avoidable bleeding may occur. Patient-tailored care may provide more effective prevention of bleeding, which in turn, may decrease the likelihood of arthropathy and associated chronic pain, missed time from school or work, and progressive loss of mobility. A strategy is presented here aiming to reduce or eliminate bleeding altogether through a holistic approach based on individual patient characteristics. In an environment of budget constraints, this approach would link procurement to patient outcome, adding incentives for all stakeholders to strive for optimal care and, ultimately, a bleed-free world.

1996-01-01

The iliopsoas or iliopectineal comportment is a normal structure that occasionally communicates with the synovial cavity of the hip. Rarely, in association with certain pathologies that raise the intraarticular pressure, it becomes enlarged, producing an inguinal or pelvic mass, also referred to as iliopsas bursitis. We present five cases of this pathology detected over the past year in our hospitals. Three of the patients had undergone previous vascular punctures in the hip involved, one presented brucellosis-related arthropathy and the fifth had generative joint abnormalities. The plain radiography, arthrography, ultrasound, CT,CT-guided arthrography and MR images are provided and discussed. We present an etiological factor of this process (previous vascular puncture) that has not been previously reported in the literature. 13 refs

Imaging of the temporomandibular joint(TMJ) is continuously evolving with advancement of imaging technologies. Many different imaging modalities are currently used to evaluate the TMJ. Magnetic resonance imaging is commonly used for evaluation of the TMJ due to its superior contrast resolution and its ability to acquire dynamic imaging for demonstration of the functionality of the joint. Computed tomography and ultrasound imaging have specific indication in imaging of the TMJ. This article focuses on state of the art imaging of the temporomandibular joint. Relevant normal anatomy and biomechanics of movement of the TMJ are discussed for better understanding of many TMJ pathologies. Imaging of internal derangements is discussed in detail. Different arthropathies and commontumors are also discussed in this article.

The present article evaluates 26 cases with arterial occlusion and additional polyneuropathy in diabetes mellitus or chronic alcohol addiction. For comparison, a group of 30 patients with arterial occlusion without neutrologically detectable polyneuropathy were also evaluated. It is pointed out that the osseous changes in the foot bone region are due to the additionally existing polyneuropathy and cannot be explained alone by an avascular bone necrosis in arterial vascular occlusion. Changes in the sense of an arthropathy occur in our group of patients even in case of unilateral arterial occlusion, these changes occurring bilaterally in the foot bones; after reconstruction measures in the arterial vascular system, these arthropathic changes in the foot bones continue to advance in case of persisting polyneuropathy.

2008-01-01

Full Text Available Alkaptonuria is a rare disorder of metabolism characterized by deficiency of homogentisic acid oxidase. Characteristic features include darkening of urine, ochronosis, and arthropathy. Darkening of urine is the only sign of the disorder in the pediatric age group, and it occurs at very early stage of the disorder, as reported by the parents. A 4-year-old boy presented to our clinic with the complaint of dark urine and bluish black staining of clothes. This darkening pointed to a positive physical history of bluish discoloration of sclerae which occurred off and on. We initiated treatment with ascorbic acid and a protein diet with restriction of phenylalanine and tyrosine (1.6 g/kg/d. This case report is significant because of the early diagnosis made.

Genetics of alkaptonuria – an overview

Full Text Available Alkaptonuria (AKU is the first described inborn error of metabolism and a classical example of rare autosomal recessive disease. AKU patients carry homozygous or compound heterozygous mutations of the gene coding for enzyme homogentisate dioxygenase (HGD involved in metabolism of tyrosine. The metabolic block in AKU causes accumulation of homogentisic acid (HGA that, with advancing age of the patient, leads to severe and painful ochronotic arthropathy. HGD gene was mapped to chromosome 3q13.3 and is composed of 14 exons. In about 400 patients, 142 pathogenic variants were reported that are listed in HGD mutations database (http://hgddatabase.cvtisr.sk/. In this review, we summarise different aspects of AKU genetics and impact of the HGD variants on enzyme function.

Clinical and in vitro studies have demonstrated that fluoroquinolones are toxic to chondrocytes; however, the exact mechanism of fluoroquinolone arthropathy is unknown. We investigated the toxicity of ciprofloxacin on normal cartilage and on cartilaginous tumors. Normal human cartilage, enchondroma...... with use of conventional light microscopy, electron microscopy, and immunohistochemistry to identify extracellular matrix, cell proliferation, and apoptosis. Cultures of normal chondrocytes expressed type-II collagen. Electron microscopy revealed a large amount of glycogen in the cells; the presence of fat...... of vimentin filaments. The treated chondrocytes showed a decrease in cell proliferation, but there was no induction of apoptosis or effect on the expression of extracellular matrix proteins. Ciprofloxacin-treated chondrosarcoma cultures and tissue samples showed changes in cartilage matrix composition...

A 67-year-old former gold miner with rheumatoid arthritis, treated with steroids and methotrexate, presented to eye casualty with a painful right eye. Examination revealed an anterior uveitis and despite an initial response to topical steroids, the intraocular inflammation worsened with anterior and posterior uveitis development. Re-examination showed a white mass in the peripheral nasal retina initially suspected of being active Toxoplasmosis infection and anti-toxoplasmosis treatment commenced. After improvement and tapering of this treatment, the intraocular inflammation reoccurred. Cytopathological examination of a pars plana vitrectomy obtained vitreous sample that showed a non-diagnostic non-infectious chronic vitritis. The vitreoretinal surgeons elected to do a direct biopsy of the white subretinal mass in the peripheral nasal area. This revealed, quite unexpectedly, an abscess containing pigmented phaeohyphomycosis fungi. This case report documents the multidisciplinary approach that assisted in clinching a final diagnosis and the role of sub-retinal biopsy in this unprecedented scenario.

The purpose of this study was to explore the midterm clinical outcomes of unicompartmental knee replacement (UKR) for medial knee arthropathy through a minimally invasive approach (MIA). From January 2006 to June 2010, 442 consecutive patients (485 knees) were included in the study. All patients underwent MIA-UKR with the mobile bearing Oxford phrase III prosthesis. The incision was made starting 1 cm medial to the medial pole of the patella and extending distally to the tibial tubercle. Radiographic evaluations include femorotibial angle (FTA) from coronal x-rays and rectified varus deformity angle, while clinical evaluations included Knee Society Score (KSS, clinical score and function score), the Western Ontario and McMaster Universities Arthritis Index (WOMAC) osteoarthritis index and visual analog scale (VAS) for pain. Patients followed-up at 1, 3, 6, 12 months after surgery and each year thereafter. Four hundreds and two patients completed the entire follow-up, 40 patients (45 knees) were lost to follow-up. The average follow-up time was 73.0 ± 1.9 months. The mean length of the incisions was 5.0 ± 0.2 cm. The average FTA decreased from 183.6° ± 5.1° preoperatively to 174.3° ± 4.2° postoperatively, and the mean rectified varus deformity angle was 9.3° ± 1.2°. The KSS clinical score improved from 42.4 ± 2.9 to 92.9 ± 3.8, and the function score improved from 53.5 ± 3.8 to 93.5 ± 4.0. The WOMAC score improved from 47.5 ± 3.1 preoperatively to 12.3 ± 1.5 at the last evaluation. The VAS dropped from 7.8 ± 1.9 preoperatively to 1.6 ± 0.2 postoperatively. All clinical evaluations (KSS, WOMAC, VAS) were significantly different (p clinical outcomes of MIA-UKR are satisfactory in a Chinese patient population, which is a good surgical option for patients with medial arthropathy of the knee. However, longer-term follow-up studies should be performed in these patients.

Extracorporeal adsorption of anti-factor VIII allo-antibodies on randomly functionalized polystyrene resins.

The occurrence of anti-factor VIII (FVIII) allo-antibodies is a severe complication of the treatment of haemophilia A patients, leading to the inhibition of transfused FVIII activity. The effective elimination of these inhibitory antibodies plays a decisive role in the management of affected patients. To achieve this, immunoadsorption devices employing synthetic adsorbers, which selectively eliminate inhibitors, are of interest in the treatment strategy of haemophilia A patients with inhibitors. Adsorbers consisting of polystyrene-based beads substituted with sulphonate and L-tyrosyl methylester groups, which mimic part of epitope of FVIII molecule recognized by inhibitors, exhibit selective binding capacities towards anti-FVIII antibodies. The adsorption of FVIII inhibitors was investigated by simulating an extracorporeal circulation of haemophilic plasma over these functionalized resins. These innovative adsorbers are able to remove around 25% of anti-FVIII antibodies in 15 minutes depending on the plasma tested. Furthermore, they do not modify the amount of essential plasmatic proteins or residual immunoglobulins G. Experiments which were carried out using different plasmas with various inhibitor titres demonstrate a good reproducibility regarding the adsorption capacity of the synthetic resin. The characteristics of adsorption are similar on either native or regenerated resins. Both the purely synthetic nature of the resin and its easy processability demonstrate the real advantages over currently available protocols. This synthetic adsorber is a major technological advance in selective removal of FVIII inhibitory antibodies.

The Nuclear Medicine Section of the IAEA has a long tradition in supporting the implementation of effective therapeutic application for the management of cancer and benign conditions. This obligation resides in Article II of the IAEA Statutes. The specific mission is to foster the application of nuclear medicine techniques in those diseases that may successfully be managed using radioisotopic applications. In addition to documents related to therapeutic application of unsealed radioisotopes, the IAEA was successful in managing a multicentre Coordinated Research Projects (CRPs) for the treatment of Hepato Cellular Carcinoma published recently in a special edition of the Seminars. Other CRPSs were aimed at improving quality of life of patients suffering from rheumatoid arthritis and haemophilic arthropathy and the palliation of disseminated metastatic bone pain. In addition, to disseminate knowledge, high level experts are invited to consultancy panels to assist in producing relevant documents in the field of Nuclear Medicine, including publications, manuals and educational material all of which are accessible on-line. The Department of Nuclear Sciences and Application (NA) has identified the need to enhance the availability and accessibility of Member States to medical radioisotopes potentially attractive for clinical use, one of these being Lutetium-177. To achieve this objective a world-wide network of cooperation was established. Since several countries operating nuclear reactors at a low to medium-neutron flux are capable of producing sufficient amounts of Lu-177 for the labelling of bone seeking radiopharmaceuticals, Lu-177 ethylenediamine tetra(methylene phosphonic acid) ( 177 Lu-EDTMP) has been identified for its clinical potential as a safe, sustainable and cost-effective radiopharmaceutical for the management of bone pain caused by metastatic prostate and breast cancer. To fulfil the highest standards of international legal requirements, animal studies and

Objective: The present study was aimed at describing uncommon presentations of intraosseous hemophilic pseudotumor in imaging diagnosis. Materials and methods: Retrospective study evaluating five hemophilic pseudotumors in bones of two patients with hemophilia A. Imaging findings were consensually evaluated by two musculoskeletal radiologists. Plain radiography, computed tomography and magnetic resonance imaging studies were analyzed. Results: At contrast-enhanced computed tomography images, one of the lesions on the left thigh was visualized with heterogeneously enhanced solid areas. This finding was later confirmed by anatomopathological study. Another uncommon finding was the identification of a healthy bone portion interposed between two intraosseous pseudotumors in the humerus. And, finally, a femoral pseudotumor with extension towards soft tissues and transarticular extension, and consequential tibial and patellar involvement. Conclusion: The above described imaging findings are not frequently reported in cases of intraosseous pseudotumors in hemophilic patients. It is important that radiologists be aware of these more uncommon presentations of intraosseous pseudotumors. (author)

The role of radiology in the evolution of the understanding of articular disease.

Science.gov (United States)

Huang, Mingqian; Schweitzer, Mark E

2014-11-01

Both the clinical practice of radiology and the journal Radiology have had an enormous effect on our understanding of articular disease. Early descriptions of osteoarthritis (OA) appeared in Radiology. More recently, advanced physiologic magnetic resonance (MR) techniques have furthered our understanding of the early prestructural changes in patients with OA. Sodium imaging, delayed gadolinium-enhanced MR imaging of cartilage, and spin-lattice relaxation in the rotating frame (or T1ρ) sequences have advanced understanding of the pathophysiology and pathoanatomy of OA. Many pioneering articles on rheumatoid arthritis (RA) also have been published in Radiology. In the intervening decades, our understanding of the natural history of RA has been altered by these articles. Many of the first descriptions of crystalline arthropathies, including gout, calcium pyrophosphate deposition, and hydroxyapatite deposition disease, appeared in Radiology.

Reactive Arthritis Secondary to Cauda Equina Injury following Spine Fracture: A Case Report

Directory of Open Access Journals (Sweden)

Xiao Li

2011-01-01

Full Text Available A 38-year-old man presented with a one-month history of muscle weakness and dysesthesia in the lower extremities, urinary retention, and urinary tract infection after lumbar burst fracture resulted from high fall. During the rehabilitation in our hospital, he had arthritis in both the ankle and knee. However, the patient was treated as gouty arthropathy initially. The arthritis was completely remitted in a few days after the patient was diagnosed as reactive arthritis and started with sulfasalazine therapy and there was no recurrence during 4 months of follow-up. Based on this case, early recognition of reactive arthritis is of major importance to avoid delayed initiation of appropriate treatment in the patients with polyarthritis secondary to neurogenic bladder following cauda equina injury after spine fracture.

Virtual anthropology and forensic identification using multidetector CT.

Virtual anthropology is made possible by modern cross-sectional imaging. Multislice CT (MSCT) can be used for comparative bone and dental identification, reconstructive identification and lesion identification. Comparative identification, the comparison of ante- and post-mortem imaging data, can be performed on both teeth and bones. Reconstructive identification, a considerable challenge for the radiologist, identifies the deceased by determining sex, geographical origin, stature and age at death. Lesion identification combines virtual autopsy and virtual anthropology. MSCT can be useful in palaeopathology, seeking arthropathy, infection, oral pathology, trauma, tumours, haematological disorders, stress indicators or occupational stress in bones and teeth. We examine some of the possibilities offered by this new radiological subspeciality that adds a new dimension to the work of the forensic radiologist. A multidisciplinary approach is crucial and involves communication and data exchange between radiologists, forensic pathologists, anthropologists and radiographers.

Radiation synovectomy is a noninvasive therapy that has been investigated as an alternative to surgical synovectomy. It is been successfully employed in the treatment of synovitis in rheumatoid arthrits and other inflammatory arthropathies. We developed the 166 Ho-chitosan complex for possible use as a radiation synovectomy agent. Holmium is the more practical isotope based on its higher radioactivity and logner half-life. And isotope based on its higher radioactivity and logner half-life. And chitosan is ideal and suitable particles based on its soluble and biodegradable characteristics. So we investigated the biocompatibility of the 166 Ho-chitosan complex to evaluated the suitability as a radiation synovectomy agent. In this study, we performed in vivo and in vitro stability test and biodistribution test. Our results indicate that 166 Ho-chitosan may be an effective radiopharmaceutical for radiation synovectomy.

1988-01-01

The authors have reviewed the radiographic patterns of the foot in 28 patients affected by neuropathic joint disease complicating alcoholism, out of a series of 82 chronic ethylic patients. Sixteen of them were also affected by diabetes mellitus. On the basis of X-ray findings, lesion were divided into tree groups, reflecting the evolution of the disease: 1) early changes, especially affecting the soft tissue and joints;2) definite lesions, consisting of fractures, osteolysis, bone destruction and amputation, periarticulardebris; 3)''healing'' signs, simulating degenerative joint disease, which cause severe and weakening deformities. Tabe dorsalis and diabetic osteoarthropathy must be differentiated from alcohol-induced syndrome. Even though a correct differential diagnosis is often difficult to reach, it must be kept in mind that focal/diffuse osteopenia is the most characteristic manifestation of alcoholic osteopathy, whereas different radiographic findings simulate chronic degenerative arthropathies

Ochronotic arthropathy related to alkaptonuria is a rare condition. Cervical spine involvement with myelopathic features has been even more rarely described, particularly related to atlantoaxial instability. As such, little is known about the optimal surgical management in these patients. We described the first case, to our knowledge, of a patient with alkaptonuria and related cervical spondylotic myelopathy from pannus formation at the atlantoaxial joint. We describe our choices in surgical management of this rare condition in a patient with an excellent outcome. Ochronotic cervical spondylotic myelopathy is a rare condition and may require additional considerations in surgical treatment compared to more common causes of cervical spondylotic myelopathy. In our case, we elected for decompression with posterior occipitocervical screw fixation and were able to achieve neurologic recovery with no complications, currently at 2-year follow-up.

We report a patient with alkaptonuria accompanied by bilateral rapidly destructive arthrosis of the hip. The destruction of the left hip joint with its severe functional impairment necessitated total hip arthroplasty (THA). The outcome was satisfactory. Both magnetic resonance imaging (MRI) and pathologic findings were compatible with a subchondral insufficiency fracture. A year and half later, during a follow-up visit, the patient complained of right coxalgia. Radiography showed that the right femoral head had already disappeared, requiring THA of the right hip. Although there have been a few reports of rapid destructive hip osteoarthritis associated with ochronotic arthropathy, the pathogenesis of the destructive change is not clear. Subchondral insufficiency fracture was diagnosed on MR imaging and pathologically confirmed in our patient with alkaptonuria, suggesting that subchondral insufficiency fracture is one of the causes of ochronotic hip destruction.

The evolution of peptide-specific CD4(+) T-cell responses to acute viral infections of humans is poorly understood. We analyzed the response to parvovirus B19 (B19), a ubiquitous and clinically significant pathogen with a compact and conserved genome. The magnitude and breadth of the CD4(+) T......-cell response to the two B19 capsid proteins were investigated using a set of overlapping peptides and gamma interferon-specific enzyme-linked immunospot assays of peripheral blood mononuclear cells (PBMCs) from a cohort of acutely infected individuals who presented with acute arthropathy. These were compared...... to those for a cohort of B19-specific immunoglobulin M-negative (IgM(-)), IgG(+) remotely infected individuals. Both cohorts of individuals were found to make broad CD4(+) responses. However, while the responses following acute infection were detectable ex vivo, responses in remotely infected individuals...

Intraoperative CT navigation for glenoid component fixation in reverse shoulder arthroplasty

Directory of Open Access Journals (Sweden)

Ashok S Gavaskar

2013-01-01

Full Text Available CT navigation has been shown to improve component positioning in total shoulder arthroplasty. The technique can be useful in achieving strong initial fixation of the metal backed glenoid in reverse shoulder arthroplasty. We report a 61 years male patient who underwent reverse shoulder arthroplasty for rotator cuff arthropathy. CT navigation was used intraoperatively to identify best possible glenoid bone and to maximize the depth of the fixation screws that anchor the metaglene portion of the metal backed glenoid component. Satisfactory positioning of screws and component was achieved without any perforation or iatrogenic fracture in the scapula. CT navigation can help in maximizing the purchase of the fixation screws that dictate the initial stability of the glenoid component in reverse shoulder arthroplasty. The technique can be extended to improve glenoid component position [version and tilt] with the availability of appropriate software.

Full Text Available Background. Hemorrhagic vasculitis, or Henoch-Schönlein purpura (HSP, in children has its onset in the form of the articular syndrome in the vast number of patients, which is a part of the diagnostic criteria of this disease. The nature of the arthritis after the disease transformation from the juvenile HSP remains unexplored. In adulthood, articular patho­logy can manifest as migratory intermittent or chronic arthritis, but this information should be clarified. The objective was to study the clinical, X-ray and sonographic features of arti­cular syndrome course in patients with HSP and to evaluate the features of arthropathy in the presence of the disease that began in childhood and adulthood. Materials and methods. The study included 174 patients with HSP (83 % of men and 47 % of women. Childhood-onset vasculitis (on average in 12 years was diagnosed in 92 patients, and adulthood-onset (on avera­ge in 25 years — in 82; I, II and III degree of activity of the pathological process are established at a ratio of 1 : 2 : 2. Results. The joint affection is observed in every second patient with HPS, which is closely related to the patient’s age at the onset of the disease, duration and degree of the activity of pathological process, seropositivity by the high content of immunoglobulin A and rheumatoid factor. At that, clinical, radiological and sonographic nature of the articular syndrome’s course (involving the wrist, hip and sacroiliac joints, the development of aseptic osteonecrosis, bone erosion, meniscitis and intraarti­cular cartilage flaps depend on extraarticular manifestations of the di­sease (lesion of heart, kidney, pancreas, central nervous system. They are accompanied by an increased concentration in the blood of β2-microglobulin and circulating immune complexes that together with the values of fibrinogenemia have predictive value. Dimorphism of HSP, transformed from a juvenile one, is characterized by the less serum levels

Full Text Available The purpose of this study was to explore the midterm clinical outcomes of unicompartmental knee replacement (UKR for medial knee arthropathy through a minimally invasive approach (MIA.From January 2006 to June 2010, 442 consecutive patients (485 knees were included in the study. All patients underwent MIA-UKR with the mobile bearing Oxford phrase III prosthesis. The incision was made starting 1 cm medial to the medial pole of the patella and extending distally to the tibial tubercle. Radiographic evaluations include femorotibial angle (FTA from coronal x-rays and rectified varus deformity angle, while clinical evaluations included Knee Society Score (KSS, clinical score and function score, the Western Ontario and McMaster Universities Arthritis Index (WOMAC osteoarthritis index and visual analog scale (VAS for pain. Patients followed-up at 1, 3, 6, 12 months after surgery and each year thereafter.Four hundreds and two patients completed the entire follow-up, 40 patients (45 knees were lost to follow-up. The average follow-up time was 73.0 ± 1.9 months. The mean length of the incisions was 5.0 ± 0.2 cm. The average FTA decreased from 183.6° ± 5.1° preoperatively to 174.3° ± 4.2° postoperatively, and the mean rectified varus deformity angle was 9.3° ± 1.2°. The KSS clinical score improved from 42.4 ± 2.9 to 92.9 ± 3.8, and the function score improved from 53.5 ± 3.8 to 93.5 ± 4.0. The WOMAC score improved from 47.5 ± 3.1 preoperatively to 12.3 ± 1.5 at the last evaluation. The VAS dropped from 7.8 ± 1.9 preoperatively to 1.6 ± 0.2 postoperatively. All clinical evaluations (KSS, WOMAC, VAS were significantly different (p < 0.05 from pre and post-operative evaluations. The survival rate was 99.1% at 73 months, and the revision rate was 0.9%.The midterm clinical outcomes of MIA-UKR are satisfactory in a Chinese patient population, which is a good surgical option for patients with medial arthropathy of the knee.

MR images of normal and pathologic human hands were obtained using a 4.7-T magnet Varian system. Standard spin-echo techniques and inversion-recovery sequences were used to produce both T1- and T2-weighted images. The higher gradient (2 gauss/cm) of the 4.7-T system allows submillimeter resolution. A specially designed surface coil is used to improve the signal-to-noise ratio. The coil is elliptical and measures 3 inches by 4.5 inches. Axial, coronal, and sagittal images were obtained, revealing fine, detailed structures of the human hand. The joint capsule, ligaments and tendons, and vascular structures were clearly visible. The authors will show images of the normal anatomy of the hand, as well as pathologic lesions of inflammatory and crystalline arthropathy. Techniques and special problems of imaging the human hand with a 4.7-T system are discussed

The large Sima de los Huesos sample provides for the first time the opportunity of performing a paleopathological study of a Middle Pleistocene population. A high frequency of bilateral temporomandibular arthropathy has been observed. We found an ear hyperostosis in Cranium 4, that probably caused deafness that we consider to be of infectious origin. Three osteomata were found in the cranial collection. One severe trauma was evident on the left supraorbital torus of an immature individual. Many cranial vault erosions, mostly restricted to the external table, are found in the sample. Cranium 5 displays thirteen of these. Cranium 5 also shows an extensive maxillary osteitis associated with a dental apical abscess, as well as another dental apical abscess in its mandible. Most of the adult frontal bones show a worm-like pattern of vascular channelling in the orbital roof, also found in modern populations.

Radiation synovectomy is a noninvasive therapy that has been investigated as an alternative to surgical synovectomy. It is been successfully employed in the treatment of synovitis in rheumatoid arthrits and other inflammatory arthropathies. We developed the {sup 166}Ho-chitosan complex for possible use as a radiation synovectomy agent. Holmium is the more practical isotope based on its higher radioactivity and logner half-life. And isotope based on its higher radioactivity and logner half-life. And chitosan is ideal and suitable particles based on its soluble and biodegradable characteristics. So we investigated the biocompatibility of the {sup 166}Ho-chitosan complex to evaluated the suitability as a radiation synovectomy agent. In this study, we performed in vivo and in vitro stability test and biodistribution test. Our results indicate that {sup 166}Ho-chitosan may be an effective radiopharmaceutical for radiation synovectomy. (author). 30 refs., 7 tabs.

The purpose of this review is to describe the spectrum of sonographic findings in rheumatic diseases with respect to the diagnostic potential using US contrast media which prove activity or inactivity in synovial tissue where new treatment regimes target. Synovial activity can be found in non-erosive and erosive forms of primary and secondary osteoarthritis, and in inflammatory forms of joint diseases like rheumatoid arthritis and peripheral manifestations of spondyloarthritis including, ankylosing spondylitis, Reiter's syndrome, psoriatic arthritis and enteropathic arthritis. It can also be present in metabolic and endocrine forms of arthritis, in connective tissue arthropathies like systemic lupus erythematosus or scleroderma and in infectious arthritis. Ultrasound should be used as first-line imaging modality in suspected early cases of RA and other forms of arthritis, whereas contrast-enhanced ultrasound (CEUS) can further enable for sensitive assessment of vascularity which correlates with disease activity

The study aimed to evaluate the ratio of venous contamination in diabetic cases without foot lesion, with foot lesion and with Charcot neuroarthropathy (CN). Bolus-chase three-dimensional magnetic resonance (MR) of 396 extremities of patients with diabetes mellitus was analyzed, retrospectively. Extremities were divided into three groups as follows: diabetic patients without foot ulcer or Charcot arthropathy (Group A), patients with diabetic foot ulcers (Group B) and patients with CN accompanying diabetic foot ulcers (Group C). Furthermore, amount of venous contamination classified as no venous contamination, mild venous contamination, and severe venous contamination. The relationship between venous contamination and extremity groups was investigated. Severe venous contamination was seen in Group A, Group B, and Group C, 5.6%, 15.2%, and 34.1%, respectively. Statistically significant difference was seen between groups with regard to venous contamination. Venous contamination following bolus chase MR was higher in patients with CN.

Critical appraisal of canakinumab in the treatment of adults and children with cryopyrin-associated periodic syndrome (CAPS)

Science.gov (United States)

Toker, Ori; Hashkes, Philip J

2010-01-01

The cryopyrin-associated syndromes (CAPS) include three autosomal-dominant syndromes, that are caused by a mutation in the NLRP3 gene on chromosome 1, encoding the cryopyrin protein. These syndromes, familial cold autoinflammatory syndrome, Muckle-Wells syndrome and neonatal-onset multisystem inflammatory disease, are characterized by urticaria-like rash, fever, central nervous system inflammation, an arthropathy and a risk of the development of amyloidosis in a respectively escalating degree of severity between the various syndromes. Recently the role of cryopyrin in the regulation of interleukin (IL)-1 production and activation was described and anti IL-1 therapies were found to be very effective in treating these syndromes. There are several types of anti IL-1 medications based on different mechanisms of antagonizing IL-1. This paper focuses on the efficacy and safety of canakinumab, a long-acting humanized anti IL-1 antibody, in treating these syndromes. PMID:20531965

BACKGROUND: Human parvovirus B19 (B19) is a ubiquitous and clinically significant pathogen, causing erythema infectiosum, arthropathy, transient aplastic crisis, and intrauterine fetal death. The phenotype of CD8+ T cells in acute B19 infection has not been studied previously. METHODS AND FINDINGS......: The number and phenotype of B19-specific CD8+ T cell responses during and after acute adult infection was studied using HLA-peptide multimeric complexes. Surprisingly, these responses increased in magnitude over the first year post-infection despite resolution of clinical symptoms and control of viraemia......, with T cell populations specific for individual epitopes comprising up to 4% of CD8+ T cells. B19-specific T cells developed and maintained an activated CD38+ phenotype, with strong expression of perforin and CD57 and downregulation of CD28 and CD27. These cells possessed strong effector function...

Analysis of non-typeable Haemophilous influenzae VapC1 mutations reveals structural features required for toxicity and flexibility in the active site.

Directory of Open Access Journals (Sweden)

Brooke Hamilton

Full Text Available Bacteria have evolved mechanisms that allow them to survive in the face of a variety of stresses including nutrient deprivation, antibiotic challenge and engulfment by predator cells. A switch to dormancy represents one strategy that reduces energy utilization and can render cells resistant to compounds that kill growing bacteria. These persister cells pose a problem during treatment of infections with antibiotics, and dormancy mechanisms may contribute to latent infections. Many bacteria encode toxin-antitoxin (TA gene pairs that play an important role in dormancy and the formation of persisters. VapBC gene pairs comprise the largest of the Type II TA systems in bacteria and they produce a VapC ribonuclease toxin whose activity is inhibited by the VapB antitoxin. Despite the importance of VapBC TA pairs in dormancy and persister formation, little information exists on the structural features of VapC proteins required for their toxic function in vivo. Studies reported here identified 17 single mutations that disrupt the function of VapC1 from non-typeable H. influenzae in vivo. 3-D modeling suggests that side chains affected by many of these mutations sit near the active site of the toxin protein. Phylogenetic comparisons and secondary mutagenesis indicate that VapC1 toxicity requires an alternative active site motif found in many proteobacteria. Expression of the antitoxin VapB1 counteracts the activity of VapC1 mutants partially defective for toxicity, indicating that the antitoxin binds these mutant proteins in vivo. These findings identify critical chemical features required for the biological function of VapC toxins and PIN-domain proteins.

Bony Reconstruction of the Anterior Glenoid Rim.

Recurrent anterior shoulder instability is associated with glenohumeral bone loss. Glenoid deficiency compromises the concavity-compression mechanism. Medial Hill-Sachs lesions can result in an off-track humeral position. Anterior glenoid reconstruction or augmentation prevents recurrence by addressing the pathomechanics. In Bristow and Latarjet procedures, the coracoid process is harvested for conjoint tendon transfer, capsular reinforcement, and glenoid rim restoration. Complications and the nonanatomic nature of the procedure have spurred research on graft sources. The iliac crest is preferred for autogenous structural grafts. Tricortical, bicortical, and J-bone grafts have shown promising results despite the historical association of Eden-Hybinette procedures with early degenerative joint disease. Allogeneic osteochondral grafts may minimize the risk of arthropathy and donor site morbidity. Tibial plafond and glenoid allografts more closely match the native glenoid geometry and restore the articular chondral environment, compared with conventional grafts. Graft availability, cost, risk of disease transmission, and low chondrocyte viability have slowed the acceptance of osteochondral allografts.

Full Text Available Spondyloepiphysial dysplasia (SED is a rare diseases which causes delayed growth, short statue and involves the centre of the vertebral epiphysis. SED congenita and SED tarda are two different clinical forms of this disease. SED tarda with progressive arthropathy is another rare clinical appearance. SED is more frequently seen in male patients due to a genetic recessive transmission by chromosome X. The disease is characterized by a delay in the formation of epipysis, shortness of spine and extremities, kyphoscoliosis, coxa vara and platyspondily. In this case report we aimed to discuss an adolescent male SED tarda patient with early onset of osteoarthritis and osteoporosis, who was diagnosed as Scheuerman disease in the orthopedics clinic and treated with growth hormone for growth retardation in the pediatric endocrinology clinic. Important findings and labotatory investigation methods for diagnosis and treatment of this diasese will be outlined. (From the World of Osteoporosis 2009;15:79-82

Full Text Available Introduction. Tuberculous (TB synovitis is a rare, treatable, potentially lethal form of extrapulmonary TB resulting from massive lymphohematogenous dissemination of Mycobacterium tuberculosis (M. tuberculosis. We presented a case of TB synovitis of the knee in a Caucasian HIV negative man from Romania, a high TB incidence country. Case report. A 65-year old man presented with cough, high fever, mild wheezing, and swelling of the left knee. Chest radiography was normal. Sputum smears were Acid Fast Bacilli negative and Löwenstein-Jensen (L-J culture negative for M. tuberculosis. Tuberculin skin test was negative. Respiratory symptoms disappeared in a week under antibiotics. Positive L-J cultures of knee punctation and favourable treatment outcome following standardized antituberculous treatment regimen confirmed the diagnosis of specific synovitis, which was also demonstrated by Magnetic Resonance Imaging (MRI. Conclusion. Tuberculous synovitis is important differencial diagnosis in patients with arthropathies and risk factors for TB in all the countries and all patients' ages even when tuberculin skin test is negative.

2013-01-01

Extensor pollicis longus (EPL) tendon rupture is a well-described phenomenon in patients with rheumatoid arthritis. Mechanisms of EPL tendon rupture in the nonrheumatoid population have also been described and include traumatic rupture, repetitive motion strain, and steroid injection into the tendon. The operative records for patients undergoing extensor pollicis longus reconstruction by the senior author were reviewed. Patients with a history of trauma to the wrist or inflammatory arthropathy were excluded. We identified 3 patients who presented with spontaneous EPL tendon rupture. These patients reported no risk factors (as listed earlier) or inciting event. All 3 patients had some exposure to local steroids but this exposure was not at the site of subsequent tendon rupture. All patients were operatively repaired and went on to full recovery of EPL function. In patients with sudden loss of extension of the thumb interphalangeal joint, a thorough history of steroid exposure including local steroid exposure remote to the affected EPL tendon may be relevant.

Disease-Associated Particulates and Joint Inflammation; Mechanistic Insights and Potential Therapeutic Targets

Directory of Open Access Journals (Sweden)

Olwyn R. Mahon

2018-05-01

Full Text Available It is now well established that intra-articular deposition of endogenous particulates, such as osteoarthritis-associated basic calcium phosphate crystals, gout-associated monosodium urate crystals, and calcium deposition disease-associated calcium pyrophosphate crystals, contributes to joint destruction through the production of cartilage-degrading enzymes and pro-inflammatory cytokines. Furthermore, exogenous wear-debris particles, generated from prosthetic implants, drive periprosthetic osteolysis which impacts on the longevity of total joint replacements. Over the last few years, significant insight has been gained into the mechanisms through which these particulates exert their effects. Not only has this increased our understanding of the pathological processes associated with crystal deposition but it has also led to the identification of a number of therapeutic targets to treat particulate-associated disease. In this review, we discuss recent developments regarding the cellular events triggered by joint-associated particulates, as well as future directions in therapy for particulate-related arthropathies.

Recurrent haemarthroses are one of the most characteristic features of hemophilia during childhood. With the aid of sup(99m)Tc-pertechnetate arthroscintigraphy was carried out in 30 children with hemophilia between 5 and 15 years of age. The 79 articulations under investigation included 42 knee-, 13 elbow- and 24 ankle-joints. The results were compared with the scanograms of 30 normal joints, the activity of the isotope varying between 89% and 130%. Among 19 joints affected by acute haemarthrosis, 11 revealed severe changes while in chronic arthropathy, 50% of the changes proved to be slight which was disclosed with the aid of scintigraphy. There is some dependence between the severity of the changes, the grade of AHG and the frequence of haemarthroses, the latter correlating with the age factor. Arthroscintigraphy is a valuable diagnostic method above all in establishing the presence of an active inflammatory process among the destructive changes in the joints of children with hemophilia.

The objective of this study was to describe the magnetic resonance imaging (MRI) features of tuberculosis (TB) of the knee joint. The MRI features in 15 patients with TB of the knee, as confirmed by histology of the biopsied joint synovium, were reviewed retrospectively. The images were assessed for intra-articular and peri-articular abnormalities. All patients had florid synovial proliferation. The proliferating synovium showed intermediate to low T2 signal intensity. In the patients who were administered intravenous contrast, the hypertrophic synovium was intensely enhancing. Marrow edema (n = 9), osteomyelitis (n = 4), cortical erosions (n = 5), myositis (n = 6), cellulitis (n = 2), abscesses (n = 3), and skin ulceration/sinus formation (n = 2) were seen in the adjacent bone and soft tissue. Synovial proliferation associated with tuberculous arthritis is typically hypointense on T2-weighted images. This appearance, in conjunction with other peri-articular MRI features described, can help in distinguishing TB arthritis from other proliferating synovial arthropathies. (orig.)

Infliximab is an accepted induction and maintenance treatment for patients with Crohn's disease. The effectiveness of infliximab has been demonstrated for both active luminal disease and for enterocutaneous fistulisation. In addition, infliximab can be administered for extraintestinal symptoms of Crohn's disease, such as pyoderma gangrenosum, uveitis and arthropathy. Maintenance treatment with infliximab is effective and is regarded as safe as long as the necessary safety measures are heeded. Infusion reactions occur in 3 to 17% of the patients and are associated with the formation of antibodies to infliximab. A reduction in infusion reactions is possible by the concurrent administration of steroids and the use of immunosuppressants (azathioprine, 6-mercaptopurine, methotrexate). Furthermore, immunosuppressants increase the duration of the response to infliximab. For these reasons, the concomitant use of immunosuppressants with infliximab is recommended. Infections and most specifically tuberculosis need to be ruled out before infliximab is administered. Up to now, there are no indications for a connection between an increased risk for malignancies and treatment with infliximab.

Full Text Available The overall prognosis for patients with ß-thalassemia has improved considerably during the past decades mainly due to regular blood transfusions, improvements in chelation therapy, and enhanced surveillance with imaging studies examining iron overload and other clinical complications. However, the prolonged survival of these patients leads to the development of other health problems including degenerative diseases such as arthropathies, which require further attention since they have a significant impact on the quality of life. In the current case report, we present a 45-year-old white man with ß-thalassemia complaining of non-traumatic pain and restriction in the range of motion of both knees. Magnetic resonance imaging (MRI revealed a tear in the medial meniscus of the left knee as well as iron deposits in both knees. Histological findings confirmed the presence of hemosiderin in both joints. To our knowledge, this is the first reported case of macroscopically documented iron deposits in the knee joints of a patient with ß-thalassemia using MRI.

Topical aspects of nuclear medical diagnostics in dermatology

1985-01-01

The diagnostic value of soft tissue and bone scintigraphy in various dermatological diseases is discussed. We received new knowledge about frequency, dimension and validity of psoriatic osteoarthropathia by using scintigraphic methods. Bone scintigraphy is more sensitive than clinical and radiological investigation and there is an earlier detection of arthropathy in psoriasis. Whole body scintigraphy using bone seeking radiopharmaceuticals has proven to be a sensitive diagnostic tool in the detection of bone and joint involvement in collagen diseases. These methods can also be of great value in the evaluation and clinical management of diseases with possible generalized or multiple bone lesions (e. g. syphilis; dermatomyositis; sarcoidosis; malignant melanoma). Since the discovery of hybridoma technique for the production of monoclonal antibodies it became apparent that this new class of immunoglobulins may represent a new useful tool in the diagnosis and in the therapy of malignant diseases. In this paper we discuss the application of murine and human monoclonal antibodies in experimental and clinical oncology. (orig.) [de

Chronic recurrent multifocal osteomyelitis (CRMO) is an unusual clinical entity. More than 200 cases are described in the literature and it is presented here with special reference to its radiological aspects. It is an acquired disease of the skeleton which occurs predominantly during childhood and adolescence. About ten per cent of cases begin in early or, rarely, in later adult life. This variant is described here for the first time and is discussed as 'adult CRMO'. The underlying pathology is a bland, predominantly lympho-plasma cellular osteomyelitis which is self-limiting and leads to bone sclerosis (Garre). It probably involves an abnormal immune process which follows an infection but remains clinically latent and remains aseptic and sterile. In a quarter of cases there is an association with pustulosis palmo-plantaris and its relationship with psoriatic arthropathy is discussed. The clinical, histopathological and imaging features (radiological and particularly MRT) and the bone changes are described. (orig./AJ) [de

Numerous measuring instruments for the evaluation of hemophilic arthropathy have been developed. One of the most used systems is the Hemophilia Joint Health Score (HJHS) given its sensitivity to clinical changes appearing in the joints because of recurrent hemarthrosis. Assessing the interrater reliability, using the Spanish version of the HJHS (version 2.1) in children with hemophilia. Reliability study to assess the interrater reliability of the Spanish version of HJHS. A sample of 36 children aged 7-13 years diagnosed with hemophilia A or B was used. Two physiotherapists performed physical assessments with the Spanish version of the HJHS. Descriptive statistics (range, mean, standard deviation) and the analysis of interrater reliability were calculated. The interrater reliability was heterogeneous since the Kappa coefficient range (ĸ), although significant (p reliability of the Spanish population version of the HJHS is high. This scale should be used generically in evaluating musculoskeletal pediatric patients with hemophilia.

Nowadays, health education has been elevated to a higher standing in healthcare systems in managing chronic illness; yet, this approach has not received sufficient support in developing countries as these societies still tend to the traditional stage of 'treatment after disease'. Adolescence is a critical period and voyage into adulthood can be more challenging for haemophilia teens. For teens with haemophilia, learning to care for their own disorder is a giant step forward in asserting their independence and preparation for adult life. We aimed to determine impact of health instructions on improving knowledge and practices of haemophilia A adolescents. An interventional study was conducted on 50 haemophilia A adolescents at outpatient clinic of Pediatric Hematology Unit of Zagazig University Hospitals. Three tools were used. The first was a structured interview sheet to evaluate patients' knowledge. The second was a clinical checklist to evaluate patients' practices. The third was health instructions program. Tools were developed by the researchers based on a thorough review of related literature and a full understanding of the needs of haemophilic adolescents. Evaluation of health instructions success was based on comparing scores of tool I and tool II before health instructions (pretest) and after health instructions immediately (posttest) and after 2 months (follow-up test). There was a significant improvement in knowledge and practices of haemophilia A adolescents in posttest and follow-up test compared to pretest. Health instructions have an impact on improving knowledge and practices of haemophilia A adolescents. © 2014 John Wiley & Sons Ltd.

To compare the CACS and CAD severity assessed by MDCT in neuropathic type-2 diabetic patients with and without Charcot-neuroarthropathy (CN). Thirty-four CN asymptomatic-patients and 36 asymptomatic-patients with diabetic-neuropathy (DN) without CN underwent MDCT to assess CACS and severity of CAD. Patients were classified as positive for significant CAD in presence of at least one stenosis >50 % on MDCT-coronary-angiography (MDCT-CA). Groups were matched for age, sex and traditional CAD risk-factors. The coronary-angiography (CA) was performed in all patients with at least a significant stenosis detected by MDCT-CA, both as reference and eventually as treatment. CN patients showed higher rates of significant CAD in comparison with DN subjects [p < 0.001], while non-significant differences were observed in CACS (p = 0.980). No significant differences were also observed in CACS distribution in all subjects for stenosis ≥/<50 % (p = 0.814), as well as in both groups (p = 0.661 and 0.559, respectively). The MDCT-CA showed an overall diagnostic-accuracy for significant CAD of 87 %. These preliminary data suggest that CN-patients have a higher prevalence of severe CAD in comparison with DN-patients, while coronary plaques do not exhibit an increased amount of calcium. MDCT may be helpful to assess the CV risk in such asymptomatic type-2-diabetic patients with autonomic-neuropathy. (orig.)

Endocrine disruptors such as phenolic compounds and parabens may be involved in chronic non-infective disease. While products incorporating these compounds are extensively utilized in consumer and personal products, little is known about their effect on bowel health. Inflammatory bowel disease (IBD) - consisting of the diseases ulcerative colitis and Crohn's disease - and irritable bowel syndrome are common chronic non-infectious diarrheal diseases. Despite limited knowledge on the etiology of IBD, these diseases have increased prevalence in industrialized countries and cause significant impairment to quality of life. In the present study we examine relationships between urinary environmental phenolic compounds, chronic diarrhea and inflammatory bowel disease. Data was obtained from the 2005–2010 US National Health and Nutrition Examination Survey (NHANES) including demographics, lifestyle factors, self-reported health conditions, inflammatory markers and urinary phenolic chemical concentrations. Only participants with complete environmental phenols & parabens component were included in our analysis. Chronic diarrheal symptoms were determined by using the 2009–2010 NHANES questionnaire which included questions pertaining to bowel health. We utilized chronic bowel leakage symptoms as a surrogate marker for chronic diarrhea. The presence of IBD was also analyzed from 2009 to 2010 NHANES data, as a sub-analysis for arthropathy directly querying the presence or absence of IBD. Among the subset of 5218 American adults aged 20–80 years in the NHANES study period who completed environmental phenols & parabens component, 25.5% reported chronic diarrheal symptoms. Abnormal markers of inflammation were present in 2200 (42.2%) of respondents. For IBD, 19 individuals with arthropathy confirmed a diagnosis of ulcerative colitis, and 1 person confirmed a Crohn's diagnosis. After adjustment for demographics, inflammatory and subsample weighing; lower paraben

Major destructive asymptomatic lumbar Charcot lesion treated with three column resection and short segment reconstruction. Case report, treatment strategy and review of literature

Full Text Available Charcot's spine is a long-term complication of spinal cord injury. The lesion is often localized at the caudal end of long fusion constructs and distal to the level of paraplegia. However, cases are rare and the literature relevant to the management of Charcot's arthropathy is limited. This paper reviews the clinical features, diagnosis, and surgical management of post-traumatic spinal neuroarthropathy in the current literature. We present a rare case of adjacent level Charcot's lesion of the lumbar spine in a paraplegic patient, primarily treated for traumatic spinal cord lesion 39 years before current surgery. We have performed end-to-end apposition of bone after 3 column resection of the lesion, 3D correction of the deformity, and posterior instrumentation using a four-rod construct. Although the natural course of the disease remains unclear, surgery is always favorable and remains the primary treatment modality. Posterior long-segment spinal fusion with a four-rod construct is the mainstay of treatment to prevent further morbidity. Our technique eliminated the need for more extensive anterior surgery while preserving distal motion

A computerized index can be used to retrieve cases from a teaching file that have radiographic findings similar to an unknown case. The probability that a user will review cases with a correct diagnosis was estimated with use of radiographic findings of arthritis in hand radiographs of 110 cases from a teaching file. The nearest-neighbor classification algorithm was used as a computer index to 110 cases of arthritis. Each case was treated as an unknown and inputted to the computer index. The accuracy of the computer index in retrieving cases with the same diagnosis (including rheumatoid arthritis, gout, psoriatic arthritis, inflammatory osteoarthritis, and pyrophosphate arthropathy) was measured. A Bayes classifier algorithm was also tested on the same database. Results are presented. The nearest-neighbor algorithm was 83%. By comparison, the estimated accuracy of the Bayes classifier algorithm was 78%. Conclusions: A computerized index to a teaching file based on the nearest-neighbor algorithm should allow the user to review cases with the correct diagnosis of an unknown case, by entering the findings of the unknown case

Gout, the most common form of microcrystalline arthropathy has always interested radiologists. The diagnosis of gout is primarily based on clinical and laboratory findings; however, it has well known and characteristic radiographic manifestations. Radiographs remain the examination of choice in the diagnosis of joint involvement. Plain radiographs are less sensitive to early changes in gout than other imaging techniques. Recently, magnetic resonance imaging (MRI), ultrasound (US), and computed tomography (CT) have demonstrated an increasing role in early diagnosis of gouty arthritis, for assessing the extent of soft-tissue involvement and as problem-solving tools for diagnostically difficult cases. Cross-sectional imaging can also be used for guiding needle aspirations in patients with an acute attack of gout, which may simulate an infective process clinically. This pictorial review illustrates the main imaging features of gout on radiographs, MRI, CT, and ultrasound with the aim of helping the radiologist to make a confident diagnosis in radiographically typical cases and to serve as a problem-solving tool in cases that present a diagnostic dilemma.

Pubalgia is a painful syndrome of the groin which particularly affects young athletes. Although soccer players are the athletes most often affected, they are not alone. Also included in this group are fencers, tennis players and rugbymen. This ailment is associated with varying degrees of lesions of the muscles of the lower frontal abdomen, pubic symphysis and adductor muscles. The clinical diagnosis is confirmed by standard X-rays which can show radiological anomalies of the pubic symphysis in cases of microtraumatic pubic osteo-arthropathy or insertion tendinitis. Scintigraphic anomalies occur earlier than radiological anomalies and return to normal before them; thus allowing confirmation of healing even when the radiographs are still abnormal. Sonogram and MRI can be advantageous in the detection of a lesion of the abdominal muscles or adductor muscles. MRI can also detect a lesion of the pubic symphysis. The principal differential diagnosis is pubic osteitis. Treatment is medical and combines rest, analgesics and anti-inflammatories. Surgery, namely Nesovic's operation, is reserved for those forms resistant to medical treatment, and must be bilateral.

This review article addresses the best evidence currently available for the effectiveness of injection therapy for musculoskeletal conditions involving the peripheral joints. The research is presented by anatomical region and areas of controversy and the need for additional research are identified. Randomized controlled trials, meta-analyses and systematic reviews are lacking that address the effectiveness of therapeutic injections to the sternoclavicular, acromioclavicular, ankle and foot joints. No research studies of any kind have been reported for therapeutic injections of the sternoclavicular joint. With the exception of the knee, possibly the hip and patients with inflammatory arthropathies, research does not unequivocally support the use of therapeutic joint injections for most of the peripheral joints, including the shoulder. Additionally, controversy exists in some areas as to whether or not corticosteroids provide better outcomes compared to local anesthetic injections alone. When viscosupplementation injections are compared to corticosteroids in patients with osteoarthritis of the knee, the evidence supports the use of viscosupplementation for more prolonged improvement in outcomes, with corticosteroids being good for short-term relief.

A detail examination of the hands and feet was performed in a group of 34 patients affected by systemic lupus erythematosus (SLE), using low-dose mammographic film and Rank Xerox selenium plate, according to current diagnostic techniques. All patients presented articular symptoms (pain and arthralgia). The high incidence (38.8%) of patients with no radiographic evidence of bone damage-even though articular symptoms are present-is emphasized. In such cases, it is very difficult to distinguish SLE from rheumatoid arthritis, especially as far as therapeutic management and prognosis are concerned. The lack of any pathognomonic radiological sign of the lupus arthritis, in the hands as well as in the feet, is then stressed. Nevertheless, artropathy in SLE is defined as a deforming unerosive arthritis, with a typical symmetric distribution, affecting most commonly (according to incidence) the proximal interphalangeal and metacarpophalangeal joints. In the hand, arthropathy is referred to as Jaccoud's type arthritis, because it is characterized by joint deformities which can be corrected. In the foot, the main abnormalities include hallux valgus, subluxation of the matatarsophalangeal joints and widening of the forefoot

Ankylosing spondylitis (AS) is closely associated with the histocompatibility antigen HLA-B27. Pathogenesis of AS is thought to involve interactions between B27 and certain enterobacterial antigens. However, enterobacterial involvement is uncertain and contested by some. The present paper demonstrates raised serum IgA to a common enterobacterial heat modifiable major outer membrane protein (h-momp; Mr 35,000) in active AS (N = 25; IgA = 1485 +/- 20) compared with controls, who were hospital patients without known arthropathies or gastro-intestinal disease (N = 12; IgA = 548 +/- 59). Serum IgG and IgM did not differ statistically. Raised serum IgA to h-momp might indicate enterobacterial antigenic stimulation from the gastro-intestinal tract and thus support an inductive contribution of enterobacterial antigens to the pathogenesis of secondary AS. It does not necessarily imply direct involvement in the pathogenesis of primary AS. H-momp appears to be a convenient tool for serological studies of AS and at present is likely to be more suitable than other bacterial antigens.

Reverse shoulder arthroplasty in young patient with achondroplasia - Ten year follow up: Case report.

van den Broek, M; Verborgt, O; Declercq, G

2017-11-01

Skeletal dysplasia in achondroplasia can affect all body joints - including the glenohumeral joint - and is prone to develop to degenerative osteoarthritis (OA). This may cause pain and mobility problems at young age. Surgical treatment is challenging due to the dysplastic anatomy of the shoulder joint - with a dysplastic deformed short humerus, a small, hypoplastic medialized glenoid and lateralized acromion - and the long life expectancy of these patients. The indications for reverse shoulder arthroplasty (RSA) evolved during years with rotator cuff tears and rotator cuff arthropathy in combination with or without glenohumeral OA as the main indicator, with good short to mid-term results. Long term results of RSA are rarely found in literature, especially in young patients. The use of a RSA in glenohumeral OA with an intact rotator cuff has rarely been reported. In this case report we present the ten-year clinical and radiographic results of a RSA for the treatment of degenerative OA with glenohumeral dysplasia in a young patient with achondroplasia.

Osteoarthritis (OA) has traditionally been defined as a prototypical non-inflammatory arthropathy, but today there is compelling evidence to suggest that it has an inflammatory component. Many recent studies have shown the presence of synovitis in a large number of patients with OA and demonstrated a direct association between joint inflammation and the progression of OA. Pro-inflammatory cytokines, reactive oxygen species (ROS), nitric oxide, matrix degrading enzymes and biomechanical stress are major factors responsible for the progression of OA in synovial joints. The aim of this review is to discuss the significance of a wide range of implicated inflammatory mediators and their contribution to the progression of OA. We also discuss some of the currently available guidelines, practices, and prospects. In addition, this review argues for new innovation in methodologies and instrumentation for the non-invasive detection of inflammation in OA by modern imaging techniques. We propose that identifying early inflammatory events and targeting these alterations will help to ameliorate the major symptoms such as inflammation and pain in OA patients.

The pathogenesis of subchondral bone lesions and growth plate affection in hemophilic arthropathy was studied in puppies by means of repeated regional /sup 99m/Tc-diphosphonate scintimetry and contact autoradiography. Unilateral hemarthrosis of the knee was induced by biweekly intraarticular injections of autologous blood for 12 weeks. Hemarthrosis caused an early (2 to 4 weeks) decrease in uptake of /sup 99m/Tc-diphosphonate in the juxtaarticular growth plates (ratio 0.7) and a delayed (8 to 10 weeks) increase in epiphyseal uptake (ratio 1.5). In a recovery phase after hemarthrosis, growth plate uptake returned to normal, while the epiphyseal uptake remained elevated for 8 to 10 weeks. By contact autoradiography, the growth plate uptake was localized to the calcification layer at the metaphyseal aspect of the growth plates, while the epiphyseal uptake mainly was seen in the thin subchondral and subsynovial bone layer and around osteophytes. The changes in uptake of /sup 99m/Tc-diphosphonate following hemarthrosis for 3 months were reversible and could be ascribed to the presence of synovial inflammation

Hydroxyapatite is very useful for various biomedical applications, due to its chemical similarity with mineralized bone of human. Hydroxyapatite is also responsible for arthropathy (joint disease). In the present study, the growth of hydroxyapatite crystals was carried out by using single-diffusion gel growth technique in silica hydro gel media, at physiological temperature. The growth of hydroxyapatite crystals under slow and controlled environment in gel medium can be simulated in a simple manner to the growth in human body. The crystals, formed in the Liesegang rings, were characterized by powder XRD, FTIR and dielectric study. The diffusion study is also carried out for the hydroxyapatite crystals using the moving boundary model. The inhibitive influence of various Ayurvedic medicinal plant extracts such as Boswellia serrata gum resin , Tribulus terrestris fruits, Rotula aquatica roots, Boerhaavia diffusa roots and Commiphora wightii, on the growth of hydroxyapatite was studied. Roots of R. aquatica and B. diffusa show some inhibition of the hydroxyapatite crystals in vitro. This preclinical study will be helpful to design the therapy for prevention of hydroxyapatite-based ailments.

The temporomandibular joint

Campbell, W.

1984-01-01

Whilst the temporomandibular joint is in many ways unique, it is subject to all the diseases and disorders found in joints in other parts of the human skeleton. By far the most common disorder is injury, followed by arthropathy, acute and chronic dislocations, ankylosis, and in rare instances, neoplasms. The diagnosis and management of the temporomandibular joint are the primary responsibility of the oral surgeon. Nevertheless, this anatomical region is an area in which the cooperation of medical and dental disciplines may be required for the satisfactory conclusion of treatment. The more so when the disease process involves either associated psychosomatic illness or malignancy. The mainstay of the diagnosis is a careful radiological examination of the joint. There exists a delicate relationship between the dentition, the muscles of mastication, and the temporomandibular articulation, which is controlled by arthrokinetic reflex activity of the branches of the 5th cranial nerve. Imbalance between one or more of the components of this integrated system frequently leads to disturbances in function. Pain-dysfunction disorders constitute the larger part of temporomandibular joint disturbances generally encountered

Due to variability in the one-stage clotting assay, the performance of new factor IX (FIX) products should be assessed in this assay. The objective of this field study was to evaluate the accuracy of measuring recombinant FIX Fc fusion protein (rFIXFc) activity in clinical haemostasis laboratories using the one-stage clotting assay. Human haemophilic donor plasma was spiked with rFIXFc or BeneFIX® at 0.80, 0.20, or 0.05 IU/ml based on label potency. Laboratories tested blinded samples using their routine one-stage assay and in-house FIX plasma standard. The mean spike recoveries for BeneFIX (n=30 laboratories) were 121 %, 144 %, and 168 % of expected at nominal 0.80, 0.20, and 0.05 IU/ml concentrations, respectively. Corresponding rFIXFc spike recoveries were 88 %, 107 %, and 132 % of expected, respectively. All BeneFIX concentrations were consistently overestimated by most laboratories. rFIXFc activity was reagent-dependent; ellagic acid and silica gave higher values than kaolin, which underestimated rFIXFc. BeneFIX demonstrated significantly reduced chromogenic assay activity relative to one-stage assay results and nominal activity, while rFIXFc activity was close to nominal activity at three concentrations with better dilution linearity than the typical one-stage assay. In conclusion, laboratory- and reagent-specific assay variabilities were revealed, with progressively higher variability at lower FIX concentrations. Non-parallelism against the FIX plasma standard was observed in all one-stage assays with rFIXFc and BeneFIX, leading to significant overestimation of FIX activity at lower levels and generally high inter-laboratory variability. Compared to the accuracy currently achieved in clinical laboratories when measuring other rFIX products, most laboratories measured rFIXFc activity with acceptable accuracy and reliability using routine one-stage assay methods and commercially available plasma standards.

Full Text Available The reproductive form of Haemophilic infection caused by a microorganism Histophilus somni (Haemophilus somnus is in our conditions practically unknown and undiscovered disease of cow reproductive organs. The aim of this work was based on experimental work to provide a comprehensive view on the patho-histological and submicroscopic changes in the uterus of 60 cows, serological positive, crossbreeds Slovenske strakate x Holstein, aged 3.5 . 4.5 years, serological positive, which were up to 90 days after the parturition sterile. After the hormonal control of the oestrus cycle (PGF2ƒż-Oestrophan SPOFA the cows were inseminated and the non-gravid cows later killed. The reproductive organs of killed animals were pathologically . anatomically dissected with following histological and sub-microscopic study of uterus and cervix tissue. At the beginning of the experiment no clinical changes of the reproductive organs of group 1 animals with the titer of antibodies 1:25-100 were diagnosed and in group 3 with the titer 1:25. At an examination before killing were examined endometritis (EM of grade II. and vaginitis with vestibulitis in these groups. At the rest of animals appeared in every level of the titer of antibodies of EM II. and EM III. EM I. were not clinically diagnosed. Dissecting examination determined EM catarrhalis and cervicis catarrhalis in all groups. The histological examination pointed to EM catarrhalis chronica, EM interstitialis chronica, EM fibrousis and cervicis catarrhalis chronica. The leucocytes gained from a uterus lavage were in a comparison with stroma leucocytes mostly polynuclear (neutrophils and in smaller amount small forms of lymfocytes. At long-term sterility of cows, because of possible H. somnus infection, we regard as priority the serodiagnostics at which is taken into consideration any level of the titer of antibodies.

Recurrent musculoskeletal haemorrhages in people with haemophilia (PwH) lead to restrictions in the locomotor system and, as a result, in physical performance, too. Due to its physical and psychological benefits, sport is increasingly re-commended for haemophilic patients. Evidence on the cost-effectiveness of sports therapy is still lacking. The aim of this study was to determine the cost-effectiveness of a 6-month programmed sports therapy (PST). The cost-effectiveness of the 6-month PST was assessed from a societal perspective alongside a RCT using cost-utility analysis. The analysis included 50 PwH with moderate-to-severe haemophilia A and B and a training period over 6 months. The health-related quality of life was measured with the EuroQoL-domain questionnaire. Resource utilization was assessed by questionnaire before and after the intervention. A cost-effectiveness acceptability curve was constructed, and sensitivity analyses were performed. During the 6-month study period, mean adjusted total healthcare costs were lower (mean difference: -22 805 EUR; 95%-CI: -73 944-48 463; P = .59) and the number of QALYs was higher in the intervention group (mean difference: 0.3733; 95%-CI: 0.0014-0.0573; P = .04). The probability of an incremental cost-effectiveness ratio <50 000 EUR per QALY was 71%. The performed sensitivity analysis confirmed these results. Results showed that the PST is effective in terms of a significant gain of QALYs. Furthermore, results weakly indicate the potential of the PST to reduce healthcare costs. Future studies should expand the observation period to have a closer look at the influence of PST on lifetime costs. © 2018 John Wiley & Sons Ltd.

Crohn's disease is a chronic inflammatory condition affecting the gastrointestinal tract at any point from the mouth to the rectum. Patients may experience diarrhea, abdominal pain, fever, weight loss, abdominal masses, and anemia. Extraintestinal manifestations of Crohn's disease include osteoporosis, inflammatory arthropathies, scleritis, nephrolithiasis, cholelithiasis, and erythema nodosum. Acute phase reactants, such as C-reactive protein level and erythrocyte sedimentation rate, are often increased with inflammation and may correlate with disease activity. Levels of vitamin B12, folate, albumin, prealbumin, and vitamin D can help assess nutritional status. Colonoscopy with ileoscopy, capsule endoscopy, computed tomography enterography, and small bowel follow-through are often used to diagnose Crohn's disease. Ultrasonography, computed axial tomography, scintigraphy, and magnetic resonance imaging can assess for extraintestinal manifestations or complications (e.g., abscess, perforation). Mesalamine products are often used for the medical management of mild to moderate colonic Crohn's disease. Antibiotics (e.g., metronidazole, fluoroquinolones) are often used for treatment. Patients with moderate to severe Crohn's disease are treated with corticosteroids, azathioprine, 6-mercaptopurine, or anti-tumor necrosis factor agents (e.g., infliximab, adalimumab). Severe disease may require emergent hospitalization and a multidisciplinary approach with a family physician, gastroenterologist, and surgeon.

Systemic use of fluoroquinolone in children

Full Text Available Fluoroquinolones are an important class of antibiotics that are widely used in adult patients because of their broad spectrum of activity, good tissue penetration, and oral bioavailability. However, fluoroquinolone use in children is limited because juvenile animals developed arthropathy in previous experiments on fluoroquinolone use. Indications for fluoroquinolone use in patients younger than 18 years, as stated by the U.S. Food and Drug Administration, include treatment of complicated urinary tract infections and postexposure treatment for inhalation anthrax. In Korea, the systemic use of fluoroquinolones has not been approved in children younger than 18 years. Although concerns remain regarding the adverse musculoskeletal effects of fluoroquinolones in children, their use in the pediatric population has increased in many circumstances. While pediatricians should be aware of the indications and adverse effects of fluoroquinolones, recent studies have shown that the risk for musculoskeletal complications in children did not significantly increase following fluoroquinolone treatment. In addition, fluoroquinolones may be particularly helpful in treating multidrug-resistant infections that have not responded to standard antibiotic therapy in immunocompromised patients. In the present article, we provide an updated review on the safety and current recommendations for using fluoroquinolones in children.

Objective: To analyze the MRI characters of hemodialysis-related osteoarthropathy in long-term dialysis recipients, and to evaluate the diagnostic value of X-ray, CT, and MRI on hemodialysis-related osteoarthropathy. Methods: The shoulders, hips, wrists and lumbar' vertebraes of 32 patients underwent X-ray and CT examinations. Twenty-six of them received MRI examinations. Results: In X-ray of 32 patients, 28 appeared osteoporosis, 11 showed bone resorption, 6 had cystic lesions, 11 had bone sclerosis, 1 had joint swelling, and 19 had soft tissue calcification. In CT of 32 patients, 32 appeared osteoporosis, 9 showed bone resorption, 12 had cystic lesions, 11 had bone sclerosis, 3 had joint swelling, and 19 had soft tissue calcification. In MRI of 26 patients, 6 appeared osteoporosis, 2 showed bone resorption, 14 showed cystic lesions, 5 had bone sclerosis, 15 had joint swelling, and 1 showed soft tissue calcification. Conclusions: X-rays plain film is the first choice for the diagnosis of hemodialysis-related osteopathy, and MRI is the first choice for the diagnosis of hemodialysis-related arthropathy. CT and MRI is pretty useful in the diagnosis of hemodialysis-related osteoarthropathy. (authors)

Carpal instability

Schmitt, R.; Froehner, S.; Coblenz, G.; Christopoulos, G.

2006-01-01

This review addresses the pathoanatomical basics as well as the clinical and radiological presentation of instability patterns of the wrist. Carpal instability mostly follows an injury; however, other diseases, like CPPD arthropathy, can be associated. Instability occurs either if the carpus is unable to sustain physiologic loads (''dyskinetics'') or suffers from abnormal motion of its bones during movement (''dyskinematics''). In the classification of carpal instability, dissociative subcategories (located within proximal carpal row) are differentiated from non-dissociative subcategories (present between the carpal rows) and combined patterns. It is essential to note that the unstable wrist initially does not cause relevant signs in standard radiograms, therefore being ''occult'' for the radiologic assessment. This paper emphasizes the high utility of kinematographic studies, contrast-enhanced magnetic resonance imaging (MRI) and MR arthrography for detecting these predynamic and dynamic instability stages. Later in the natural history of carpal instability, static malalignment of the wrist and osteoarthritis will develop, both being associated with significant morbidity and disability. To prevent individual and socio-economic implications, the handsurgeon or orthopedist, as well as the radiologist, is challenged for early and precise diagnosis. (orig.)

Charcot's spine is a long-term complication of spinal cord injury. The lesion is often localized at the caudal end of long fusion constructs and distal to the level of paraplegia. However, cases are rare and the literature relevant to the management of Charcot's arthropathy is limited. This paper reviews the clinical features, diagnosis, and surgical management of post-traumatic spinal neuroarthropathy in the current literature. We present a rare case of adjacent level Charcot's lesion of the lumbar spine in a paraplegic patient, primarily treated for traumatic spinal cord lesion 39 years before current surgery. We have performed end-to-end apposition of bone after 3 column resection of the lesion, 3D correction of the deformity, and posterior instrumentation using a four-rod construct. Although the natural course of the disease remains unclear, surgery is always favorable and remains the primary treatment modality. Posterior long-segment spinal fusion with a four-rod construct is the mainstay of treatment to prevent further morbidity. Our technique eliminated the need for more extensive anterior surgery while preserving distal motion. © The Authors, published by EDP Sciences, 2017.

Buried chip skin grafting in neuropathic diabetic foot ulcers following vacuum-assisted wound bed preparation: enhancing a classic surgical tool with novel technologies.

In patients with diabetes mellitus, complications such as polyneuropathy and peripheral angiopathy inevitably lead to diabetic foot complications including foot ulcers, gangrene, and osteoarthropathy. These conditions necessitate minor or major amputation as part of treatment. In patients with Charcot's arthropathy and predominant neuropathy, recurrent foot ulcers are common in areas of high pressure. Such high pressure is caused by the degrading of the architecture of the foot and inadequate footwear. These patients are a clinical challenge. A select group of such patients may benefit from free surgical tissue transfer, though free or local flap surgery is often difficult or even impossible owing to an impaired arterial circulation. In such wounds, surgical debridement followed by skin grafts often fail due to bacterial burden in the wounds. To circumvent these problems, the authors developed a therapeutic approach using buried chip skin grafting to close granulation wound beds in diabetic feet. Locally applied vacuum therapy (VAC) for wound bed preparation of chronic, nonresponsive foot ulcers and subsequent grafting using the burying technique with a minute fraction of skin was used. Firm closure was achieved. The closed wound was resistant to mechanical irritation.

Currently full dose prophylaxis is the standard of care in the treatment of hemophilia (World Federation of Hemophilia). However, the high costs prevent the use of standard or intermediate dose prophylaxis in China and other developing countries. Low dose prophylaxis would be a viable alternative treatment. At present global research data on the use of low dose prophylaxis is limited. Areas covered: Since 2007, China has been developing low dose prophylaxis as a high priority (90 % of moderate and severe hemophilia boys suffer joint disease by age 6 - 9). 11 studies were successfully conducted and published results showing evidence of the benefits of low dose prophylaxis to reduce joint bleeding. This new knowledge has been implemented into clinical practice in China. However the long-term outcome of arthropathy remains unclear and obstacles in execution exist. Expert commentary: In 2016, the first phenotype-based individualized prophylaxis study using four escalating low dose regimens on severe Chinese hemophilia A boys (China Individualized Prophylaxis Study (CHIP China)) launched. Using the previously published and imminent CHIP data, the goal for China is to establish an effective escalating low dose prophylaxis protocol for use in China as a standard of care.

Primary synovial osteochondromatosis (PSOC) is a rare but clinically significant cause of morbidity especially in the male population. Surgery is the primary treatment of choice, but the recurrence rate is reported to be high. Moreover, the presence of widespread loose bodies makes it a cumbersome procedure. The complete removal of the disease is tough at times and results in early recurrence. Radiosynovectomy is an established technique for treating various joint arthropathies. The role of radiosynovectomy in case of PSOC has not yet been explored. This case report described the case of a young male with PSOC of the knee joint who was treated with radiosynovectomy for pain relief. The patient reported complete relief from the pain along with significant improvement in joint mobility. The post-therapy three-phase bone scan also validated the reduction in joint inflammation. The patient was taken for surgical removal of the redundant loose bodies after a significant improvement in the pain and reduction in inflammation. Post-therapy radiation fibrosis of the synovium also helped in the en bloc removal of the disease. The role of radiosynovectomy in PSOC needs to be further explored concerning its potential role as an adjuvant to surgical procedures

The main clinical manifestations of Whipple's disease are weight loss, arthropathy, diarrhea and abdominal pain. Cardiac involvement is frequently described. However, endocarditis is rare and is not usually the initial presentation of the disease. To the best of our knowledge, this is the first reported case of a patient with Tropheryma whipplei tricuspid endocarditis without any other valve involved and not presenting signs of arthralgia and abdominal involvement. We report a case of a 50-year-old Caucasian man with tricuspid endocarditis caused by Tropheryma whipplei, showing signs of severe shock and an absence of other more classic clinical signs of Whipple's disease, such as arthralgia, abdominal pain and diarrhea. Tropheryma whipplei was documented by polymerase chain reaction of the blood and pleural fluid. The infection was treated with a combined treatment of doxycycline, hydroxychloroquine and sulfamethoxazole-trimethoprim for one year. Tropheryma whipplei infectious endocarditis should always be considered when facing a blood-culture negative endocarditis particularly in right-sided valves. Although not standardized yet, treatment of Tropheryma whipplei endocarditis should probably include a bactericidal antibiotic (such as doxycycline) and should be given over a prolonged period of time (a minimum of one year).

Genetics of hyperuricemia and gout: implications for the present and future.

2013-02-01

Gout is the most common inflammatory arthropathy and occurs in the setting of elevated serum urate levels. Gout is also known to be associated with multiple comorbidities including cardiovascular disease and the metabolic syndrome. Recent advances in research have increased our understanding and improved our knowledge of the pathophysiology of gout. Genome-wide association studies have permitted the identification of several new and common genetic factors that contribute to hyperuricemia and gout. Most of these are involved with the renal urate transport system (the uric acid transportasome), generally considered the most influential regulator of serum urate homeostasis. Thus far, SCL22A12, SCL2A9, and GLUT9 have been found to have the greatest variation and most influence on serum urate levels. However, genetics are only a part of the explanation in the development of hyperuricemia and gout. As results have been mixed, the role of known urate influential genes in gout's associated comorbidities remains unclear. Regardless, GWAS findings have expanded our understanding of the pathophysiology of hyperuricemia and gout, and will likely play a role in the development of future therapies and treatment of this ancient disease.

Glenohumeral arthritis secondary to massive rotator cuff tear presents with a superior displacement and femoralization of the humeral head with coracoacromial arch acetabularization. The purpose of this study was to establish prevalence of rotator cuff tear artropathy (CTA) at our institution. Four hundred electronic records were reviewed from which we identified 136 patients with rotator cuff tears. A second group was composed with patients with massive cuff tears that were analized and staged by the Seebauer cuff tear arthropathy classification. Thirty four patients with massive rotator cuff tears were identified, 8 male and 26 female (age 60.1 ± 10.26 years). Massive rotator cuff tear prevalence was 25%. CTA prevalence found in the rotator cuff group was 19 and 76% in the massive cuff tears group. Patients were staged according to the classification with 32% in stage 1a, 11% 1b, 32% 2a and 0% 2b. CTA prevalence in patients with rotator cuff tears and massive cuff tears is higher than the one reported in American population. We consider that a revision of the Seebauer classification to be appropriate to determine its reliability.

Full Text Available Gout, calcium pyrophosphate dihydrate (CPPD deposition disease, and calcium hydroxyapatite deposition disease (HADD are the three most common crystal-induced arthropathies. Multimodality imaging may help in their diagnosis, and is useful for a precise and comprehensive assessment and grading of the related osteoarticular damage. Plain film radiography, due to its low cost and wide availability, is the first imaging technique to be used in crystal deposition diseases, providing well-known and specific findings for CPPD deposition disease and HADD, while it may undergrade the early osteoarticular lesions in gouty patients. Ultrasonography (US is a radiation-free approach that accurately depicts crystal deposits in cartilage, peri- and intra-articular soft tissues, but it does not give a panoramic view of the affected joints. Cross-sectional imaging techniques can examine crystal deposits in the spine and axial joints. CT has the potential to distinguish monosodium urate (MSU crystals from calcium containing crystals, due to their different attenuation values. MRI may demonstrate synovitis, erosions and bone marrow edema in gouty patients and it may differentiate tophi from other soft tissue nodules due to its high contrast resolution and power of tissue characterization.

The role of prophylactic factor VIII (FVIII) to decrease hemophilic bleeding and arthropathy is well established. The rationale for this strategy is to convert patients with severe hemophilia A to a moderate clinical phenotype by reducing time spent with a FVIII level break-through bleeding in patients with severe hemophilia A on prophylaxis. This study analysed data from 44 patients aged 1-6 and 99 patients aged 10-65 years with severe hemophilia A (FVIII safety and efficacy of a recombinant FVIII (Advate). Each patient had pharmacokinetic measurements and FVIII infusions recorded, and these were used to calculate time spent with a FVIII below 1, 2 and 5 IU dL(-1). The data demonstrate that increasing time with a FVIII below 1 IU dL(-1) is associated with increased total bleeds and hemarthroses. Lack of adherence to the intended frequency of FVIII infusion was the most important determinant of low FVIII and increased bleeding. In children aged 1-6 years, the rate of bleeding was also influenced by FVIII half-life and clearance. These data have important implications for the management of patients with severe hemophilia.

Anti-inflammatory effects of polyphenols in arthritis.

2018-03-01

Polyphenols have been extensively investigated with regard to their antioxidant, anti-inflammatory, and immunomodulant properties in many inflammatory chronic conditions. The aim of this review is to summarise how these compounds can modulate the inflammatory pathways which characterise the most prevalent arthropathies including osteoarthritis, rheumatoid arthritis and crystal-induced arthritis. Among polyphenols, epigallocatechin gallate, carnosol, hydroxytyrosol, curcumin, resveratrol, kaempferol and genistein have been the most widely investigated in arthritis. The most important results of the studies outlined in this article show how polyphenolic compounds are able to inhibit the expression and the release of a number of pro-inflammatory mediators and proteolytic enzymes, the activity of different transcriptional factors and the production of reactive oxygen species in vitro. Studies on animal models of rheumatoid arthritis, osteoarthritis and gout show interesting results in terms of reduced tissue damage, restored cartilage homeostasis, and decreased levels of uric acid, respectively. Despite the multiple protective effects of polyphenols, there are no dietary recommendations for patients affected by rheumatic diseases. Future studies, including intervention trials, should be conducted to determine the relevance of polyphenols consumption or supplementation in arthritis. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

2007-01-01

Parvovirus (PV) B19 is the causative agent of the childhood disease erythema infectiosum. An association of PV B19 with chronic arthropathies, sometimes resembling rheumatoid arthritis or juvenile idiopathic arthritis (JIA), has repeatedly been described. Other studies, however, have failed to identify any such relationship. In order to study further whether there is a link between PV B19 and JIA, we determined the prevalence of PV B19 specific IgG antibodies in serum samples from children with rheumatoid diseases and compared it with the prevalence in unaffected children We reasoned that if there is an association between PV B19 and JIA, then the prevalence of PV B19 IgG in the children with JIA should be higher than in the control group. PV B19 IgG status was tested in 406 children with JIA and related diseases, and in 146 children constituting a control group. The percentage of PV B19 IgG positive children was not significantly elevated in the disease subgroups compared with age-matched control groups. In conclusion, our findings do not support the hypothesis that human parvovirus B19 is involved in the pathogenesis of JIA. PMID:17760961

Parvovirus B19, a member of the Erythrovirus genus of Parvoviridae family, causes various clinical illnesses including infectious erythema, arthropathy, hydrops fetalis or congenital anemia, and transient aplastic crises. The B19 virus can be transmitted through respiratory secretions, blood products, and blood transfusion. The aim of this study was to detect the B19 virus in thalassemia patients in Isfahan, Iran. The prevalence of parvovirus B19 infection was compared between thalassemia major patients and healthy subjects. Plasma samples were collected from 30 thalassemia patients from Isfahan, Iran. Thirty patients without any blood complications were considered as the control group. After DNA extraction from the plasma samples, polymerase chain reaction was performed for parvovirus B19 detection. The parvovirus B19-specific nucleotide sequence was detected in 6 patients (20%). None of the samples obtained from the 30 control subjects tested positive for B19. In this study B19-Parvovirus infection were detected in patients with hematologic disorders in comparison with control subjects. Screening of patients with a high risk of parvovirus B19 infection can considerably reduce the incidence and prevalence of B19 infection.

Necrosis of the femoral head after /sup 60/Co radiation therapy

A patient (50-year-old woman) received 10500 rad of skin dose and 630 rad of tumor dose for treatment of cervical cancer 15 years ago. The depth dose at the hip-joint was 3590 rad at the right hip-joint and 4315 rad at the left. Hip-joint pain occurred about 15 years after the irradiation, and one more year later she could not walk because of severe pain. X-ray films revealed great bone destruction at the both hip-joints as well as necrosis of the femoral head and arthropathy. The same findings were seen at the ilium, ischium, and pubis. Histologically, the synovial membrane was highly thick, fibrotic, and cicatricial. Obstructive changes were observed also in the small arteries. A severe narrowing or obstruction was observed in the Harversian canal at the bone cortex. The femoral head at the whole area was necrotic. The trabeculae were entirely thinned and were partially thickened by appositional bone formation. This new bone was also necrotic. Edematous fibrous-fatty tissues predominated the bone marrow. There was no proliferation of fibrous cell or new bone formation at the sites other than the margin.

Osteoarthritis is the most common type of arthropathy and after cardiovascular diseases is the most disabling disease in developing countries. The dosimetry for the clinical application of 153-samarium-hydroxymacroaggregates ( 153 Sm-HM) for radiation synovectomy (RSV) and palliative treatment for arthritic pain, as far as we know, has not been reported. The aim of this research was to estimate the radiation dose necessary for synovial ablation and pain palliation with minimum risk to the patient. 153 Sm-HM (370 MBq) was administered intra-articularly in a patient with severe knee pain and hindered motility. Regions of interest drawn on sequential, conjugated, anterior and posterior scintigraphy images were used to obtain the respective activity. The data was entered into a knee joint histological-geometric model designed with micrometric dimensions to represent the synovial cell layers. The Monte Carlo code was used to calculate the absorbed dose in each of the 12 model-cells representing the distance from the synovial liquid to the cartilage or bone. The absorbed dose in the synovial cavity was 114 Gy which is sufficient energy for RSV. The treated patient referred little pain and higher motility with no adverse reactions. 153 Sm-HM is a potentially valid radiopharmaceutical for RSV, which effectively palliates knee pain.

To determine trends in incidentally detected age- and gender-associated chondrocalcinosis on pelvic CT. Twenty patients of each gender at the center of each decade of life who underwent a CT scan of the pelvis performed 2009-2013 were identified and selected for a total of 400 pelvic CTs. Images were reviewed independently by two radiologists for the presence or absence of chondrocalcinosis within the pelvis. Patients with hip or low back pain, known CPPD arthropathy or any known predisposing condition, prior hip arthroplasty, or articular fracture were excluded. Logistic regression was used to predict the presence/absence of chondrocalcinosis as a function of patient age and gender. The presence/absence of chondrocalcinosis was found to be associated with patient age (p = 0.016) but not patient gender (p = 0.929). In the pelvis, chondrocalcinosis was most frequently identified at the pubic symphysis. Incidental chondrocalcinosis was not identified in any patients under 50 years of age. Chondrocalcinosis increased in frequency from 12.5 at 55 years of age to 27.5 % of patients 95 years of age. Chondrocalcinosis is common and more prevalent in late adulthood, occurs without a gender predilection, and is infrequently identified in patients younger than 50 years of age. (orig.)

Recommendations of the Brazilian Society of Rheumatology for the diagnosis and treatment of chikungunya fever. Part 2 - Treatment

Directory of Open Access Journals (Sweden)

Claudia Diniz Lopes Marques

Full Text Available Abstract Chikungunya fever has become an important public health problem in countries where epidemics occur because half of the cases progress to chronic, persistent and debilitating arthritis. Literature data on specific therapies at the various phases of arthropathy caused by chikungunya virus (CHIKV infection are limited, lacking quality randomized trials assessing the efficacies of different therapies. There are a few studies on the treatment of musculoskeletal manifestations of chikungunya fever, but these studies have important methodological limitations. The data currently available preclude conclusions favorable or contrary to specific therapies, or an adequate comparison between the different drugs used. The objective of this study was to develop recommendations for the treatment of chikungunya fever in Brazil. A literature review was performed via evidence-based selection of articles in the databases Medline, SciELO, PubMed and Embase and conference proceedings abstracts, in addition to expert opinions to support decision-making in defining recommendations. The Delphi method was used to define the degrees of agreement in 2 face-to-face meetings and several online voting rounds. This study is part 2 of the Recommendations of the Brazilian Society of Rheumatology (Sociedade Brasileira de Reumatologia - SBR for the Diagnosis and Treatment of chikungunya fever and specifically addresses treatment.

Full Text Available This update develops the actual therapeutic options in the management of the joint involvement of calcium pyrophosphate deposition disease (CPPD, basic calcium phosphate (BCP deposition disease, hemochromatosis (HH, ochronosis, oxalosis, and Wilson’s disease. Conventional pharmaceutical treatment provides benefits for most diseases. Anti-interleukine-1 (IL-1 treatment could provide similar results in CPPD than in gout flares. There is only limited evidence about the efficacy of preventive long-term colchicine intake, methotrexate, and hydroxychloroquine in chronic CPPD. Needle aspiration and lavage have satisfactory short and midterm results in BCP. Extracorporeal shockwave therapy has also proved its efficacy for high-doses regimes. Phlebotomy does not seem to have shown real efficacy on joint involvement in HH so far. Iron chelators’ effects have not been assessed on joint involvement either, while IL-1 blockade may prove useful. NSAIDs have limited efficacy on joint involvement of oxalosis, while colchicine and steroids have not been assessed either. The use of nitisinone for ochronotic arthropathy is still much debated, but it could provide beneficial effects on joint involvement. The effects of copper chelators have not been assessed either in the joint involvement of Wilson’s disease. NSAIDs should be avoided because of the liver affection they may worsen.

The J-bone graft is presumably representative of iliac crest bone grafts in general and allows anatomic glenoid reconstruction in cases of bone defects due to recurrent traumatic anterior shoulder dislocations. As a side effect, these grafts have been observed to be covered by some soft, cartilage-like tissue when arthroscopy has been indicated after such procedures. To evaluate the soft tissue covering of J-bone grafts by use of magnetic resonance imaging (MRI) and histological analysis. Case series; Level of evidence, 4. Patients underwent MRI at 1 year after the J-bone graft procedures. Radiological data were digitally processed and evaluated by segmentation of axial images. Independent from the MRI analysis, 2 biopsy specimens of J-bone grafts were harvested for descriptive histological analysis. Segmentation of the images revealed that all grafts were covered by soft tissue. This layer had an average thickness of 0.87 mm compared with 1.96 mm at the adjacent native glenoid. Of the 2 biopsy specimens, one exhibited evident hyaline-like cartilage and the other presented patches of chondrocytes embedded in a glycosaminoglycan-rich extracellular matrix. J-bone grafts are covered by soft tissue that can differentiate into fibrous and potentially hyaline cartilage. This feature may prove beneficial for delaying the onset of dislocation arthropathy of the shoulder.

to evaluate the profile of patients submitted to post-bariatric plastic surgery at the North Wing Regional Hospital, Brasília, DF. we conducted a prospective, descriptive and analytical study of patients submitted to Roux-en-Y gastroplasty, and subsequently to plastic surgery, from January 2011 to December 2016. We assessed body mass index before gastroplasty and after surgery plastic surgery, postoperative complications and comorbidities. we studied 139 patients (130 women and nine men), with a mean age of 41 years, who underwent 233 operations. The mean BMI at the time of plastic surgery was 27.44kg/m2. The mean weight loss was 47.02kg and the mean maximum BMI was 45.17kg/m2. The mean time between bariatric surgery and plastic surgery was 42 months. The most important co-morbidities before plastic surgery were arterial hypertension (11.5%), arthropathy (5.4%), diabetes mellitus (5%) and metabolic syndrome (4.3%) (pprofile of post-bariatric patients who underwent plastic surgery was similar to that reported in the literature, except for the low rate of associated surgeries and postoperative complications. Plastic surgery in post-bariatric patients has led to an improvement in the quality of life in most of these patients.

Revisiting the pathogenesis of podagra: why does gout target the foot?

Full Text Available Abstract This invited paper provides a summary of a keynote lecture delivered at the 2011 Australasian Podiatry Conference. Gout is the most prevalent inflammatory arthropathy. It displays a striking predilection to affect the first metatarsophalangeal joint as well as joints within the mid-foot and ankle. A number of factors are known to reduce urate solubility and enhance nucleation of monosodium urate crystals including decreased temperature, lower pH and physical shock, all of which may be particularly relevant to crystal deposition in the foot. An association has also been proposed between monosodium urate crystal deposition and osteoarthritis, which also targets the first metatarsophalangeal joint. Cadaveric, clinical and radiographic studies indicate that monosodium urate crystals more readily deposit in osteoarthritic cartilage. Transient intra-articular hyperuricaemia and precipitation of monosodium urate crystals is thought to follow overnight resolution of synovial effusion within the osteoarthritic first metatarsophalangeal joint. The proclivity of gout for the first metatarsophalangeal joint is likely to be multi-factorial in origin, arising from the unique combination of the susceptibility of the joint to osteoarthritis and other determinants of urate solubility and crystal nucleation such as temperature and minor physical trauma which are particularly relevant to the foot.

Destructive spondyloarthropathy (DSA) has been observed in patients undergoing long-term hemodialysis. The pathophysiology of this condition is still unknown, but there is evidence that amyloid depositions play an important role in its development. Despite several reports, the radiological evolution of these lesions is poorly known. The authors report the results of the radiographic follow-up (12-18 months) of 9 cases (7 female and 2 male patients; age 63±6 years) hemodilized for over 60 months (mean: 126±33). In 7 cases. radiographic patterns of destructive arthropathy were seen in peripheral joints as well. X-ray pictures demonstrated: 1) increased erosion of vertebral end plates (in all cases); 2) increased narrowing of invertebral spaces (in 5 cases); 3) increased collapse of vertebral bodies (in 5 cases); 4) increased malalignment of the involved segments (in 4 cases). In 3 autopsied cases β 2 -microglobulin amyloid depositions were found in disc and ligamentous paravertebral tissue. These results confirm that: 1) DSA is progressive in longterm hemodialysis patients; 2) radiographic evolution is often very quick; 3) the cervical spine is the most frequently involved location and the one where lesions are quickest to develop; 4) severe malalignament of the involved spine may be present, with subsequent neurological complications

Full Text Available Ankylosing spondylitis (AS is a systemic autoimmune disease mainly affecting the lumbar spine and sacroiliac joints, and exhibits peripheral inflammatory arthropathy. More than 25 loci have been identified as associated with AS. Because both AS and rheumatoid arthritis (RA are autoimmune diseases that may share some common genetic factors, we therefore examined if the newly identified RA genetic polymorphisms were associated with AS in a Taiwanese population. In this study, we enrolled 475 AS patients and 11,301 healthy subjects from a Taiwanese biobank as controls. Although none of single-nucleotide polymorphisms (SNPs were associated with the susceptibility to AS, the AS disease index Bath AS Global (BAS-G clinical phenotype was observed as significantly correlated to the AA genotype of rs657075 (CSF2. The significance remains after gender/age/disease duration adjustment and after group categorization by human leukocyte antigen-B 27 (HLA-B27 genotype. We further investigated the possible functions of rs657075 through bioinformatics approaches. Results revealed that polymorphism of rs657075 is able to influence the expression of acyl-CoA synthetase long-chain family member 6 (ACSL6. In conclusion, our study indicated that rs657075 (CSF2 is strongly associated with the AS disease index Bath AS Global (BAS-G clinical phenotype.

Twenty-four patients had abnormal sacroiliac joints detected by quantitative sacroiliac scintigraphy but no radiological evidence of sacroiliitis on original investigation. They were studied again after intervals of 12 to 36 months. Four patients developed radiological change. Two young, HLA B27-positive men had undoubted ankylosing spondylitis, and a young woman had possible ankylosing spondylitis. A middle-aged man had changes that could be attributed to post-traumatic osteoarthrosis. Of the remaining 20 cases, 15 had symptoms and signs suggestive of inflammatory disease of the axial skeleton (and peripheral arthropathy in 5 cases). The sexes were affected equally (8 females, 7 Males), and only 2 of the 15 were B27-positive. The response to anti-inflammatory medication was generally good to excellent, and scintiscans tended to improve. Of the remaining 5 patients, 3 had mechanical or traumatic problems, and in 2 there was no explanation for the abnormal sacroiliac scintiscan. It is concluded that quantitative sacroiliac scintigraphy may detect ankylosing spondylitis prior to the development of radiological change and that it can identify an organic basis for backache in patients with a spondylitis-like syndrome. The clinical circumstances must be taken into account, as scintigraphic abnormalities are not diagnostic of any specific disease entity. (author)

Cervical spinal cord dysfunction can result from either traumatic or nontraumatic causes, including tumors, infections, and degenerative changes. In this article, we review the range of degenerative spinal disorders resulting in progressive cervical spinal cord compression and propose the adoption of a new term, degenerative cervical myelopathy (DCM). DCM comprises both osteoarthritic changes to the spine, including spondylosis, disk herniation, and facet arthropathy (collectively referred to as cervical spondylotic myelopathy), and ligamentous aberrations such as ossification of the posterior longitudinal ligament and hypertrophy of the ligamentum flavum. This review summarizes current knowledge of the pathophysiology of DCM and describes the cascade of events that occur after compression of the spinal cord, including ischemia, destruction of the blood-spinal cord barrier, demyelination, and neuronal apoptosis. Important features of the diagnosis of DCM are discussed in detail, and relevant clinical and imaging findings are highlighted. Furthermore, this review outlines valuable assessment tools for evaluating functional status and quality of life in these patients and summarizes the advantages and disadvantages of each. Other topics of this review include epidemiology, the prevalence of degenerative changes in the asymptomatic population, the natural history and rates of progression, risk factors of diagnosis (clinical, imaging and genetic), and management strategies.

How early should psoriatic arthritis be treated with a TNF-blocker?

LENUS (Irish Health Repository)

Harty, Leonard

2012-02-01

PURPOSE OF REVIEW: Psoriatic arthritis (PsA) is the second most commonly identified inflammatory arthropathy in early arthritis clinics. It is a complex multisystem disease involving the skin and joints, but may also present with inflammation of the spine - spondylitis, digits - dactylitis, eyes - uveitis and ligamentous insertions - enthesitis. The skin manifestations may be mild or patchy and often precede the joint inflammation. Joint erosions, however, may occur within the first 2 years in up to half of PsA patients and an erosion rate of 11% per annum has been reported suggesting it is not a benign disease as it was once regarded. RECENT FINDINGS: Therapy with mild anti-inflammatories is only beneficial in very mild or localized disease. In cases of more widespread joint involvement systemic therapy with disease-modifying antirheumatic drugs (DMARDs) such as methotrexate may be required and in the case of extra-articular or spinal disease, in which DMARDs have failed to show efficacy, biologic therapy may be highly effective. SUMMARY: The question of how early treatment should be instituted should be decided in a specialist rheumatology referral centre following appropriate assessment. Optimal therapy with combination DMARD and biologics may result in remission rates of up to 60%.

Gout is a form of crystal arthropathy where monosodium urate (MSU) crystals deposit and elicit inflammation in a joint. Diagnosis of gout relies on identification of MSU crystals under a compensated polarized light microscope (CPLM) in synovial fluid aspirated from the patient’s joint. The detection of MSU crystals by optical microscopy is enhanced by their birefringent properties. However, CPLM partially suffers from the high-cost and bulkiness of conventional lens-based microscopy, and its relatively small field-of-view (FOV) limits the efficiency and accuracy of gout diagnosis. Here we present a lens-free polarized microscope which adopts a novel differential and angle-mismatched polarizing optical design achieving wide-field and high-resolution holographic imaging of birefringent objects with a color contrast similar to that of a standard CPLM. The performance of this computational polarization microscope is validated by imaging MSU crystals made from a gout patient’s tophus and steroid crystals used as negative control. This lens-free polarized microscope, with its wide FOV (>20 mm2), cost-effectiveness and field-portability, can significantly improve the efficiency and accuracy of gout diagnosis, reduce costs, and can be deployed even at the point-of-care and in resource-limited clinical settings.

Pain and microcrystalline arthritis

Full Text Available Microcrystals are responsible for some of the most common and complex arthropathies which are often accompanied by intense, severe pain and inflammatory reactions. The main pathogens are crystals of monosodium urate (MSU, responsible for the gout, calcium pyrophosphate (CPP, which deposits also in various clinical forms of arthopathies, and basic calcium phosphate associated with osteoarthritis. In this context, the microcrystal arthritis is characterized by multiple, acute attacks followed by chronic pain, disability, impaired quality of life, and increased mortality. Given their chronic nature, they represent an ever more urgent public health problem. MSU and CPP crystals are also able to activate nociceptors. The pain in mycrocrystalline arthritis (MCA is an expression of the inflammatory process. In the course of these diseases there is an abundant release of inflammatory molecules, including prostaglandins 2 and kinins. Interleukin-1 represents the most important cytokine released during the crystal-induced inflammatory process. Therefore, clinically, pain is the most important component of MCA, which lead to functional impairment and disability in a large proportion of the population. It is fundamental to diagnose these diseases as early as possible, and to this aim, to identify appropriate and specific targets for a timely therapeutic intervention.

Medtep Hemophilia platform is an online tool that allows patients with congenital coagulopathies to keep track of their daily condition-related events with the objective of ensuring successful adherence to therapy. To assess the effectiveness of Medtep Hemophilia in improving adherence to prophylactic treatment in haemophilia A and B patients in a 1-year prospective observational study, as well as its impact on the patient's disease status. Patients (>13 years old) received support material to familiarize themselves with Medtep Hemophilia. Adherence to treatment, quality of life (QoL) and illness perception were assessed. Values at baseline, 1, 6 and 12 months, and changes from baseline value were analysed. The Hemophilia Joint Health Score (HJHS) test was applied at baseline and study completion. Forty-six patients were enrolled (43 evaluable). After 1 year, 56.4% patients showed continued use of the platform (100% compliance) whereas 25.6% were inactive. Treatment adherence increased both significantly (P 80% of platform use) tended to score better than noncompliant. The HJHS test values remained similar during the study. The Medtep Hemophilia online platform helped the studied patients with haemophilia to improve their adherence to prophylactic treatment, while increasing their QoL and illness perception, as well as joint arthropathies stabilization. © 2018 John Wiley & Sons Ltd.

Purpose: To examine the influence of different doses of gadolinium contrast agent on synovial enhancement, to compare magnetic resonance imaging (MRI) findings of synovial hypertrophy and radiographic joint changes in hemophiliacs, and to investigate the value of gadolinium in MRI assessment of synovial hypertrophy in hemophiliacs using dynamic MRI and MRI scoring. Material and Methods: Twenty-one hemophiliacs on prophylactic factor treatment without recent bleeds were subjected to radiography and gadolinium contrast-enhanced dynamic and static MRI of the knee using a standard dose of 0.1 mmol/kg b.w. gadoteridol. In 17 of the patients, the MRI procedure was repeated after a triple dose of gadoteridol. Results: MRI findings of synovial hypertrophy were significantly correlated with Pettersson radiographic scores. In 19 of the 21 MRI investigated joints, administration of contrast agent did not alter the result of the evaluation of synovial hypertrophy. Conclusion: The optimal time interval for volume assessment of synovial hypertrophy after injection of gadolinium contrast agent is dose dependent. Hemophiliacs without recent bleeds have minor to abundant synovial hypertrophy in joints with pronounced radiographic changes. Dynamic MRI is not useful for evaluating hemophilic arthropathy, and gadolinium contrast agent is not routinely indicated for MRI scoring of joints in hemophiliacs.

Introduction Recurrent joint hemarthroses due to hemophilia (Factor VIII and Factor IX deficiency) often lead to invasive orthopedic interventions to decrease frequency of bleeding and/or to alleviate pain associated with end-stage hemophilic arthropathy. Aim Identify trends in invasive orthopedic interventions among people with hemophilia who were enrolled in the Universal Data Collection (UDC) program during the period 2000–2010. Methods Data were collected from 130 hemophilia treatment centers in the United States annually during the period 2000–2010, in collaboration with the Centers for Disease Control and Prevention (CDC). The number of visits in which an invasive orthopedic intervention was reported was expressed as a proportion of the total visits in each year of the program. Invasive orthopedic interventions consisted of arthroplasty, arthrodesis, and synovectomy. Joints included in this study were the shoulder, elbow, hip, knee, and ankle. Results A 5.6% decrease in all invasive orthopedic interventions in all joints of people with hemophilia enrolled in the UDC program over the 11-year study period was observed. Conclusions These data reflect a declining trend in invasive orthopedic interventions in people with hemophilia. Further research is needed to understand the characteristics that may influence invasive orthopedic interventions. PMID:27030396

2012-01-01

Full Text Available Temporomandibular joint and the pelvic complex are bidirectionally related. Ankylosing spondylitis (AS is a seronegative arthropathy with the key feature of bony fusion of lumbar vertebrae. A 39 year old known case of AS was presented to private office for left lower impacted third molar surgical removal. Previously, he was rejected to receive oral care for pulpectomy and extraction due to limited mouth opening. Prior to the surgery, lateral neck radiography was obtained to exclude any subluxation of fracture of cervical vertebrae. Neck was supported to insure neck stability during surgical forces. In addition, considering consumption of immunosuppressive medications including corticosteroids, procedure was performed with a great care, with attention to higher possibility of infection and fracture. Access to the surgical site was not desirable, though surgery accomplished without any significant event and the patient discharged with routine analgesic and antibiotics recommendation. Sometimes, impaired access to the oral cavity in patients with AS leads to receive suboptimal or minimal orodental care. Long list of dental implications in these patients may be simplified by considering of careful neck and jaw support, applying at least possible forces and great attention to the infection control rules. It is wised to be performed under patient and skilled hands.

To determine trends in incidentally detected age- and gender-associated chondrocalcinosis on pelvic CT. Twenty patients of each gender at the center of each decade of life who underwent a CT scan of the pelvis performed 2009-2013 were identified and selected for a total of 400 pelvic CTs. Images were reviewed independently by two radiologists for the presence or absence of chondrocalcinosis within the pelvis. Patients with hip or low back pain, known CPPD arthropathy or any known predisposing condition, prior hip arthroplasty, or articular fracture were excluded. Logistic regression was used to predict the presence/absence of chondrocalcinosis as a function of patient age and gender. The presence/absence of chondrocalcinosis was found to be associated with patient age (p = 0.016) but not patient gender (p = 0.929). In the pelvis, chondrocalcinosis was most frequently identified at the pubic symphysis. Incidental chondrocalcinosis was not identified in any patients under 50 years of age. Chondrocalcinosis increased in frequency from 12.5 at 55 years of age to 27.5 % of patients 95 years of age. Chondrocalcinosis is common and more prevalent in late adulthood, occurs without a gender predilection, and is infrequently identified in patients younger than 50 years of age. (orig.)

Update on the pharmacological treatment of adult myositis.

2016-07-01

The management of patients with idiopathic inflammatory myopathy (IIM) remains a challenge given the systemic features beyond active myositis. That is, recognizing the inflammatory arthropathy, varying dermatomyositis rashes, and overt and occult features of interstitial lung disease in addition to myositis adds to the complexity of diagnosis and treatment of IIM. However, clinicians now have available many more immunosuppressive drugs as well as biologic agents for use in patients with myositis and other autoimmune diseases. Here, the use of these agents is reviewed and support based on available published literature is provided even though many studies have been small and results somewhat anecdotal. Glucocorticoids remain the initial treatment of choice in most instances and methotrexate and azathioprine are often used early in the treatment course. These agents are followed by other immunosuppressive drugs, for example mycophenolate mofetil, tacrolimus, cyclosporine and cyclophosphamide, some of which are used alone while combinations of these agents also provide an effective option. There is more rationale for the use of biologic agents such as rituximab from a mechanistic perspective and, given the incorporation of validated core set measures in assessing myositis patients, we can look forward to better designed clinical trials in the future. © 2016 The Association for the Publication of the Journal of Internal Medicine.

The reverse shoulder prosthesis is a prosthesis that has been in clinical use in Europe since 1985 and was approved for use in the United States in 2004. This unique prosthesis has a baseplate attached to the glenoid, which holds a spherical component, while the humeral component includes a polyethylene insert that is flat. This design is the ''reverse'' configuration of that seen with a conventional arthroplasty, in which the spherical component is part of the humeral component. The indications for the reverse prosthesis are: (1) painful arthritis associated with irreparable rotator cuff tears (cuff tear arthropathy), (2) failed hemiarthroplasty with irreparable rotator cuff tears, (3) pseudoparalysis due to massive, irreparable rotator cuff tears, (4) some reconstructions after tumor resection, and (5) some fractures of the shoulder not repairable or reconstructable with other techniques. This prosthesis can produce a significant reduction in pain and some improvement in function for most of the indications mentioned. However, the unique configuration and the challenge of its insertion can result in a high incidence of a wide variety of unusual complications. Some of these complications, such as dislocation of the components, are similar to conventional shoulder replacement. Other complications, such as notching of the scapula and acromial stress fractures, are unique to this prosthesis. (orig.)

Objective: To determine the presenting features of patients with systemic lupus erythematosus at a private hospital in Karachi, and to compare the features with those of other Asian populations. Methods: The retrospective study comprised records of all lupus cases meeting the revised American Rheumatism Association criteria at the time of presentation at Jinnah Medical College Hospital, Karachi, from May 2008 to June 2011. Demographic and clinical data was analysed using SPSS 11.5. Results: Of the 105 cases in the study, there were 6 (5.7%) males and 99 (94.3%) females, with a male-to-female ratio of 1:16 and a mean age of 31.6+-10.5 years. Clinical manifestations included: constitutional symptoms in (n=69; 65.7%), arthropathy (n=81; 77%), cutaneous involvement (n=39; 37%), lupus nephritis (n=24; 22.8%), pleurisy (n=9; 8.6%), Raynaud's phenomenon (n=24; 22.8%), and vasculitis (n=18; 17%). One (0.95%) patient presented with mononeuritis multiplex, and 1 (0.95%) with acute pancreatitis. Conclusion: The diversity in clinical presentation appeared to be a reflection of the great variability that exists among Asian countries with regards to their genetic, environmental and socio-demographic backgrounds. The differences also existed in our own population, suggesting some unknown etiology. (author)

Neoprene Orthopaedic Supports: An Underrecognised Cause of Allergic Contact Dermatitis

Full Text Available Thioureas, often contained within neoprene to provide water resistance, are an important cause of allergic contact dermatitis (ACD in those who use neoprene products. We wish to present three cases of thiourea-induced ACD from three different orthopaedic supports containing neoprene. The first case was a 67-year-old woman who developed an itchy rash on her heel three weeks after using a neoprene insole for plantar fasciitis. The second case was a 47-year-old man who developed an itchy rash on his wrist after wearing neoprene wrist splints for psoriatic arthropathy. The third case was a 77-year-old woman who experienced a severe erythematous rash with blistering from a neoprene elbow brace she received following a humeral fracture. All patients were patch tested to the British Society of Cutaneous Allergy Standard and rubber series and a cut piece from all the relevant supports. At 96 hours, all patients had a + reaction to mixed dialkylthiourea, diethylthiourea, and the supports’ material. No other positive patch test reactions were identified. As neoprene is fast becoming one of the most popular materials used for orthopaedic supports, awareness of this reaction and close liaison between dermatologists and orthopaedic surgeons are therefore essential to allow for early recognition of this complication.

Cryopyrin-associated periodic syndrome (CAPS) comprises a group of rare, but severe, autoinflammatory syndrome, and includes 3 distinct conditions, familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), and neonatal-onset multisystem inflammatory disease (MONID). These syndromes are characterized by urticarial-like rash, periodic fever, central nervous system inflammation, an arthropathy, and the risk of amyloidosis. About 20% die by age 20 years in the most severe cases. The disease is associated with mutations in the NLRP3 gene that encodes for the protein cryopyrin, a component of the inflammasome complex that regulates the production and secretion of IL-1β. Canakinumab is a human IgG monoclonal antibody targeting IL-1β. The clinical trials of canakinumab for patients with CAPS in both western countries and Japan were well-tolerated in most patients, and provided significant advantages over existing competitive therapies. Although no serious adverse effects have been reported, the frequencies of common infectious diseases including nasopharyngitis, upper respiratory tract infections, and gastroenteritis were reported presumably due to the blockade of proinflammatory cytokine, IL-1β. For us pediatrician, it will be important to be more careful for infectious diseases to provide the maximum safety of canakinumab for these patients.

The reverse shoulder prosthesis is a prosthesis that has been in clinical use in Europe since 1985 and was approved for use in the United States in 2004. This unique prosthesis has a baseplate attached to the glenoid, which holds a spherical component, while the humeral component includes a polyethylene insert that is flat. This design is the ''reverse'' configuration of that seen with a conventional arthroplasty, in which the spherical component is part of the humeral component. The indications for the reverse prosthesis are: (1) painful arthritis associated with irreparable rotator cuff tears (cuff tear arthropathy), (2) failed hemiarthroplasty with irreparable rotator cuff tears, (3) pseudoparalysis due to massive, irreparable rotator cuff tears, (4) some reconstructions after tumor resection, and (5) some fractures of the shoulder not repairable or reconstructable with other techniques. This prosthesis can produce a significant reduction in pain and some improvement in function for most of the indications mentioned. However, the unique configuration and the challenge of its insertion can result in a high incidence of a wide variety of unusual complications. Some of these complications, such as dislocation of the components, are similar to conventional shoulder replacement. Other complications, such as notching of the scapula and acromial stress fractures, are unique to this prosthesis. (orig.)

Full Text Available Abstract Introduction The main clinical manifestations of Whipple's disease are weight loss, arthropathy, diarrhea and abdominal pain. Cardiac involvement is frequently described. However, endocarditis is rare and is not usually the initial presentation of the disease. To the best of our knowledge, this is the first reported case of a patient with Tropheryma whipplei tricuspid endocarditis without any other valve involved and not presenting signs of arthralgia and abdominal involvement. Case presentation We report a case of a 50-year-old Caucasian man with tricuspid endocarditis caused by Tropheryma whipplei, showing signs of severe shock and an absence of other more classic clinical signs of Whipple's disease, such as arthralgia, abdominal pain and diarrhea. Tropheryma whipplei was documented by polymerase chain reaction of the blood and pleural fluid. The infection was treated with a combined treatment of doxycycline, hydroxychloroquine and sulfamethoxazole-trimethoprim for one year. Conclusion Tropheryma whipplei infectious endocarditis should always be considered when facing a blood-culture negative endocarditis particularly in right-sided valves. Although not standardized yet, treatment of Tropheryma whipplei endocarditis should probably include a bactericidal antibiotic (such as doxycycline and should be given over a prolonged period of time (a minimum of one year.

The most common cause of osteoarthritis of the ankle is post-traumatic, and although tibiotalar arthrodesis remains the surgical gold standard, a number of techniques have been described to preserve joint mobility, such as joint distraction arthroplasty or arthrodiastasis. To evaluate the functional outcome and changes in Visual Analogue Scale (VAS) for pain after the application of the distraction arthroplasty for post-traumatic ankle osteoarthritis. A prospective comparative study of a group of 10 young patients with post-traumatic ankle osteoarthritis treated by synovectomy and arthrodiastasis, compared to a control group of 10 patients treated by isolated synovectomy. Results were calculated using the AOFAS scale and the VAS for pain before and after treatment. As regards the pain measured by VAS, no difference was observed between the two groups before surgery (P=.99), but there was a difference at 3 months (P<.001), 6 months (P=.005), and 12 months (P=.006). No differences were observed in the AOFAS scale between the two groups before surgery (P=.99), or at 3 months (P<.99), but there was a difference at 6 months (P<.001). Ankle arthrodiastasis is effective in reducing pain in post-traumatic ankle arthropathy, and is superior to isolated synovectomy. © 2013 SECOT. Published by Elsevier Espana. All rights reserved.

Hemophilia Care in the Pediatric Age

Directory of Open Access Journals (Sweden)

Marta Bertamino

2017-05-01

Full Text Available Hemophilia is the most common of the severe bleeding disorders and if not properly managed since early infancy can lead to chronic disease and lifelong disabilities. However, it enjoys the most efficacious and safe treatment among the most prevalent monogenic disorders. Hemophilia should be considered in the neonatal period in the case of unusual bleeding or in the case of positive family history. Later, hemophilia should be suspected mainly in males because of abnormal bruising/bleeding or unusual bleeding following invasive procedures—for example, tonsillectomy or circumcision. Prophylactic treatment that is started early with clotting-factor concentrates has been shown to prevent hemophilic arthropathy and is, therefore, the gold standard of care for hemophilia A and B in most countries with adequate resources. Central venous access catheters and arterovenous fistulas play an important role in the management of hemophilia children requiring repeated and/or urgent administration of coagulation factor concentrates. During childhood and adolescence, personalized treatment strategies that suit the patient and his lifestyle are essential to ensure optimal outcomes. Physical activity is important and can contribute to better coordination, endurance, flexibility and strength. The present article focuses also on questions frequently posed to pediatric hematologists like vaccinations, day-care/school access and dental care.

The effectiveness of potentially powerful therapeutics, including DNA, is often limited by their inability to permeate the cell membrane efficiently. Electroporation (EP) also referred to as 'electropermeabilization' of the outer cell membrane renders this barrier temporarily permeable by inducing 'pores' across the lipid bilayer. For in vivo EP, the drug or DNA is delivered into the interstitial space of the target tissue by conventional means, followed by local EP. EP pulses of micro- to millisecond duration and field strengths of 100-1500 V cm{sup -1} generally enhance the delivery of certain chemotherapeutic drugs by three to four orders of magnitude and intracellular delivery of DNA several hundred-fold. We have used EP in clinical studies for human cancer therapy and in animals for gene therapy and DNA vaccination. Late stage squamous cell carcinomas of the head and neck were treated with intratumoural injection of bleomycin and subsequent EP. Of the 69 tumours treated, 25% disappeared completely and another 32% were reduced in volume by more than half. Residence time of bleomycin in electroporated tumours was significantly greater than in non-electroporated lesions. Histological findings and gene expression patterns after bleomycin-EP treatment indicated rapid apoptosis of the majority of tumour cells. In animals, we demonstrated the usefulness of EP for enhanced DNA delivery by achieving normalization of blood clotting times in haemophilic dogs, and by substantially increasing transgene expression in smooth muscle cells of arterial walls using a novel porous balloon EP catheter. Finally, we have found in animal experiments that the immune response to DNA vaccines can be dramatically enhanced and accelerated by EP and co-injection of micron-sized particles. We conclude that EP represents an effective, economical and safe approach to enhance the intracellular delivery, and thus potency, of important drugs and genes for therapeutic purposes

Adverse drug reaction and toxicity caused by commonly used antimicrobials in canine practice

Full Text Available An adverse drug reaction (ADR is a serious concern for practicing veterinarians and other health professionals, and refers to an unintended, undesired and unexpected response to a drug that negatively affects the patient's health. It may be iatrogenic or genetically induced, and may result in death of the affected animal. The ADRs are often complicated and unexpected due to myriad clinical symptoms and multiple mechanisms of drug-host interaction. Toxicity due to commonly used drugs is not uncommon when they are used injudiciously or for a prolonged period. Licosamides, exclusively prescribed against anaerobic pyoderma, often ends with diarrhoea and vomiting in canines. Treatment with Penicillin and β-lactam antibiotics induces onset of pemphigious vulgare, drug allergy or hypersensitivity. Chloroamphenicol and aminoglycosides causes Gray's baby syndrome and ototoxicity in puppies, respectively. Aminoglycosides are very often associated with nephrotoxicity, ototoxicity and neuromuscular blockage. Injudicious use of fluroquinones induces the onset of arthropathy in pups at the weight bearing joints. The most effective therapeutic measure in managing ADR is to treat the causative mediators, followed by supportive and symptomatic treatment. So, in this prospective review, we attempt to bring forth the commonly occurring adverse drug reactions, their classification, underlying mechanism, epidemiology, treatment and management as gleaned from the literature available till date and the different clinical cases observed by the authors.

Cervical Facet Joint Infection and Associated Epidural Abscess with Streptococcus intermedius from a Dental Infection Origin A Case Report and Review.

Pyogenic cervical facet joint infections are rare and such infections from a dental origin are even less common. Of these few cases, none have described infection with Streptococcus intermedius as the pathogen. A 65-year-old orthopaedic surgeon complained of fevers, right-sided radiating neck pain, stiffness, swelling, erythema, and right upper extremity weakness one month after he had broken a crown over his right mandibular premolar, a continued source of pain. Imaging of the cervical spine showed a right C4-C5 facet inflammatory arthropathy and a small epidural abscess that was cultured and initially treated with intravenous antibiotics. The oral maxillofacial surgery team performed an extraction of the infected, symptomatic tooth. For continued right upper extremity weakness, the patient underwent C4-C5 laminoforaminotomy and irrigation and debridement of the right C4-C5 facet joint. After 6 weeks of intravenous antibiotics, the patient's infectious and inflammatory markers had normalized. By 4 months, he had regained full strength at his upper extremity and a painless and full range of motion of his cervical spine.Pyogenic cervical facet joint infection is very rare and potentially dangerous. A high clinical suspicion and appropriate imaging, including magnetic resonance imaging, are important for correct diagnosis. Prompt medical and surgical treatment may avert complications, and although the patient presented made a complete recovery, patients may be left with neurological compromise.

Full Text Available Objective: we proposed to determine the clinical significance of anti-NuMA and anti-HsEg5 antibodies in a group of patients affected with rheumatic diseases. Materials and methods: indirect immunofluorescence on HEp-2000 cells at serum dilution of 1:40 was used to examin 26 sera which had previously showed a “mitotic spindle” fluoroscopic pattern type during laboratory routine. Results: 21 sera (80,7% were identified with NuMA and 5 (19,3% with HsEg5 patterns alone or associated with other ANA patterns. However only patients with isolated positiveness and that is 15 with NuMA and 4 with HsEg5 stainings were included in this study. Of the NuMA positive patients 5 were affected with arthropathies associated to different forms of thyroiditis, 2 with seronegative arthritis, 2 with antiphospholipid syndrome, 1 with systemic lupus erythematosus (SLE, 1 with rheumatoid arthritis, 1 with sicca syndrome, 1 with undifferentiated connective tissue disease, 1 with Mycoplasma pneumaniae infection and 1 with retinal thrombosis. Of the HsEg5 positive patients 3 were affected with SLE and 1 with seronegative arthritis. Conclusions: NuMA does not prevail in any defined rheumatic disease, while HsEg5 staining were more frequent (75% in patients affected with SLE all of whom showing high antibody titres.

An analysis was made on relationship between Notching and functional and radiographic parameters after treatment of acute proximal humeral fractures with reverse total shoulder arthroplasty. A retrospective evaluation was performed on 37 patients with acute proximal humeral fracture treated by reversed shoulder arthroplasty. The mean follow-up was 24 months. Range of motion, intraoperative and postoperative complications were recorded. Nerot's classification was used to evaluate Notching. Patient satisfaction was evaluated with the Constant Score (CS). Statistical analysis was performed to evaluate the relationship between Notching and glenosphere position, or functional outcomes. Mean range of elevation, abduction, external and internal rotation were 106.22°, 104.46°, 46.08° and 40.27°, respectively. Mean CS was 63. Notching was present at 12 months in 29% of patients. Statistical analysis showed significance differences between age and CS, age and notching development, and tilt with notching. No statistical significance differences were found between elevation, abduction, internal and external rotation and CS either with scapular or glenosphere-neck angle. Reverse shoulder arthroplasty is a valuable option for acute humeral fractures in patients with osteoporosis and cuff-tear arthropathy. It leads to early pain relief and shoulder motion. Nevertheless, it is not exempt from complications, and long-term studies are needed to determine the importance of notching. Copyright © 2014 SECOT. Published by Elsevier Espana.

Full Text Available Toshiyuki YamamotoDepartment of Dermatology, Fukushima Medical University, Fukushima, JapanAbstract: Psoriatic arthritis (PsA is an inflammatory arthropathy associated with cutaneous psoriasis, which is currently classified as a seronegative spondyloarthropathy. The presence of cutaneous psoriasis is important for correct and early diagnosis of PsA, because the onset of cutaneous lesions usually precedes the appearance of joint manifestation. Thus, dermatologists are able to detect the condition at its inception. PsA has several unique characteristics such as enthesopathy, dactylitis, and abnormal bone remodeling. In particular, dactylitis occurs on the easily observed sites such as digits, and is thus a significant indicator of PsA. It is important to observe not only the fingers but also the toes, because dactylitis involves both digits of the hands and feet. Recently, new ideas regarding the involvement of the interleukin (IL-23/Th17 axis have emerged, and the dramatic effects of targeting therapies have highlighted the physiological roles of key cytokines such as tumor necrosis factor-α, IL-17A, and IL-23 in psoriasis. As recent insights are shedding light on the pathogenesis of PsA, understanding of the pathogenesis of dactylitis and enthesitis are also progressing. In this article, current views on the optimal management of dactylitis are discussed.Keywords: pathogenesis, therapy, enthesitis, tenosynovitis

Alkaptonuria (AKU) is a rare autosomal recessive disease, associated with deficiency of homogentisate 1,2-dioxygenase activity in the liver. This leads to an accumulation of homogentisic acid (HGA) and its oxidized derivatives in polymerized form in connective tissues especially in joints. Currently, AKU lacks an appropriate therapy. Hence, we propose a new treatment for AKU using the antioxidant N-acetylcysteine (NAC) administered in combinations with ascorbic acid (ASC) since it has been proven that NAC counteracts the side-effects of ASC. We established an in vitro cell model using human articular primary chondrocytes challenged with an excess of HGA (0.33 mM). We used this experimental model to undertake pre-clinical testing of potential antioxidative therapies for AKU, evaluating apoptosis, viability, proliferation, and metabolism of chondrocytes exposed to HGA and treated with NAC and ASC administered alone or in combination addition of both. NAC decreased apoptosis induced in chondrocytes by HGA, increased chondrocyte growth reduced by HGA, and partially restored proteoglycan release inhibited by HGA. A significantly improvement in efficacy was found with combined addition of the two antioxidants in comparison with NAC and ASC alone. Our novel in vitro AKU model allowed us to demonstrate the efficacy of the co-administration of NAC and ASC to counteract the negative effects of HGA for the treatment of ochronotic arthropathy.

Alkaptonuria (AKU) is an inborn error of catabolism due to a deficient activity of homogentisate 1,2-dioxygenase. Patients suffer from a severe arthropathy, cardiovascular and kidney disease but other organs are affected, too. We found secondary amyloidosis as a life-threatening complication in AKU, thus opening new perspectives for its treatment. We proved that methotrexate and anti-oxidants have an excellent efficacy to inhibit the production of amyloid in AKU model chondrocytes. Owing to the progressive and intractable condition, it seems important to detect amyloid deposits at an early phase in AKU and the choice of specimens for a correct diagnosis is crucial. Ten AKU subjects were examined for amyloidosis; abdominal fat pad aspirates, labial salivary gland, cartilage and synovia specimens were analysed by CR, Th-T, IF, TEM. Amyloid was detected in only one abdominal fat pad specimen. However, all subjects demonstrated amyloid deposition in salivary glands and in other organ biopsies, indicating salivary gland as the ideal specimen for early amyloid detection in AKU. This is, at the best of our knowledge, the first report providing correct indications on the diagnosis of amyloidosis in AKU, thus offering the possibility of treatment of such co-morbidity to AKU patients.

Alkaptonuria: a very rare metabolic disorder.

Science.gov (United States)

Aquaron, Robert

2013-10-01

Alkaptonuria (AKU) is a very rare autosomal recessive disorder of tyrosine metabolism in the liver due to deficiency of homogentisate 1,2 dioxygenase (HGD) activity, resulting in the accumulation of homogentisic acid (HGA). Circulating HGA pass into various tissues through-out the body, mainly in cartilage and connective tissues, where its oxidation products polymerize and deposit as a melanin-like pigment. Gram quantities of HGA are excreted in the urine. AKU is a progressive disease and the three main features, according the chronology of appearance, are: darkening of the urine at birth, then ochronosis (blue-dark pigmentation of the connective tissue) clinically visible at around 30 yrs in the ear and eye, and finally a severe ochronotic arthropathy at around 50 yrs with spine and large joints involvements. Cardiovascular and renal complications have been described in numerous case report studies. A treatment now is available in the form of a drug nitisinone, which decreases the production of HGA. The enzymatic defect in AKU is caused by the homozygous or compound heterozygous mutations within the HGD gene. This disease has a very low prevalence (1:100,000-250,000) in most of the ethnic groups, except Slovakia and Dominican Republic, where the incidence has shown increase up to 1:19,000. This review highlights classical and recent findings on this very rare disease.

Clinical detection of gout can be difficult due to co-existent and mimicking arthropathies and asymptomatic disease. Understanding of the distribution of urate within the body can aid clinical diagnosis and further understanding of the resulting pathology. Our aim was to determine this distribution of urate within the extremities in patients with gout. All patients who underwent a four-limb dual-energy computed tomography (DECT) scan for suspected gout over a 2-year period were identified (n = 148, 121 male, 27 female, age range, 16-92 years, mean = 61.3 years, median = 63 years). The reports of the positive cases were retrospectively analyzed and the locations of all urate deposition recorded and classified by anatomical location. A total of 241 cases met the inclusion criteria, of which 148 cases were positive. Of these, 101 (68.2 %) patients had gout in the foot, 81 (56.1 %) in the knee, 79 (53.4 %) in the ankle, 41 (27.7 %) in the elbow, 25 (16.9 %) in the hand, and 25 (16.9 %) in the wrist. The distribution was further subcategorized for each body part into specific bone and soft tissue structures. In this observational study, we provide for the first time a detailed analysis of extremity urate distribution in gout, which both supports and augments to the current understanding based on clinical and microscopic findings.

To clarify the status of home care massage services provided to patients. This will help in understanding how many patients utilize this service and the circumstances under which treatment is provided. A retrospective study. Fifty-four acupuncture, moxibustion, and massage clinics. Participants were patients who had received home care massage for six months or more. We collected a total of 1587 responses from these 54 massage clinics; of these, 1415 responses (mean age = 79.1 ± 11.5 years) were valid (valid response rate 89.2%). Actual patients and actual care services. The most common disorder observed among patients who utilized home care massage services was cerebrovascular disease (at approximately 36%), while the second most common were arthropathy-related disorders (16.3%). Although most patients received massage, approximately 30% received manual therapy (e.g. manual correction) and hot fomentation as part of thermotherapy. Notably, only around 10% of patients received massage alone; the majority received treatment in combination with range of motion and muscle-strengthening exercises. This study helped to clarify the actual state of patients receiving home care massage and the details of the massage services provided. This study clearly showed the treatment effectiveness of massage, which can be used by home medical care stakeholders to develop more effective interventions. Copyright © 2018 Elsevier Ltd.

Full Text Available Objective. To explore the correlation between matrix metalloproteinase- (MMP- 3 and histological synovitis in rheumatoid arthritis (RA. Methods. Serum MMP-3 of 62 patients with active RA was detected by ELISA. Serial synovial tissue sections from all RA patients, 13 osteoarthritis, and 10 orthopedic arthropathies patients were stained with hematoxylin and eosin and immunohistochemically for MMP-3, CD3, CD20, CD38, CD68, and CD15. Results. The percentage of lining MMP3+ cells was significantly higher in RA patients especially with high grade synovitis and it was significantly correlated with Krenn’s synovitis score r=0.574, P<0.001 and sublining inflammatory cells. Multivariate stepwise linear regression analysis revealed that the association of the percentage of lining MMP3+ cells with activation of synovial stroma, sublining CD68+ macrophages, and CD15+ neutrophils was stronger than other histological indicators. The percentage of lining MMP3+ cells was significantly correlated with serum MMP-3 in RA r=0.656, P<0.001. Serum MMP-3 was higher in RA patients with high grade synovitis than that of low grade synovitis and significantly correlated with synovitis score and activation of synovial stroma subscore (all P<0.05. Conclusion. Serum MMP-3 may be an alternative noninvasive biomarker of histological synovitis and RA diagnosis.

In 21 horses with the anamnesis backproblems there had been a clinical, scan- and X-ray-examination of the thoracal and lumbar vertebra in special consideration of the spinosus process and the dorsal intervertebral joint. But there was not always a relation between the clinical signs and X-rays or scan results. Not all positive X-rays found their corresponding scan activity and not all scan activities took place in X-rays. In many cases there was pathological change of the spinosus process and arthropathy of the dorsal intervertebral joint at the same time. Only with X-raying it is not possible to decide to operate the thoracolumbal, interspinale syndrom (TIS) or not [German] Bei 2l Pferden mit dem Vorbericht 'Rückenleiden' wurden klinisch, röntgenologisch und szintigraphisch die Brust- und Lendenwirbelsäule unter besonderer Berücksichtigung der Dornfortsätze und der dorsalen Intervertebralgelenke untersucht. Die erhobenen klinischen, röntgenologischen und szintigraphischen Befunde stimmten nicht immer überein. So waren nicht alle erhobenen Röntgenbefunde szintigraphisch aktiv, und für die szintigraphisch aktiven Zonen konnten nicht immer rötgenologische Befunde erhoben werden. Bei den Veränderungen der Dornfortsätze lagen oft gleichzeitig Arthrosen der dorsalen Intervertebralgelenke vor. Die Indikation ftir die Operation des thorakolumbalen, interspinalen Syndroms (TIS) kann deshalb nicht mit der Röntgenuntersuchung der Dornfortsätze allein gestellt werden.

Craniomandiublar disorders involving the facial anatomy may be difficult to demonstrate in planar images. Although bone scanning is generally more sensitive than radiography, facial bone anatomy is complex and focal areas of increased or decreased radiotracer may become obscured by overlapping structures in planar images. Thus SPECT appears ideally suited to examination of the facial skeleton. A series of patients with craniomandibular disorders of unknown origin were imaged using 20 mCi Tc-99m MDP. Planar and SPECT (Siemens 7500 ZLC Orbiter) images were obtained four hours after injection. The SPECT images were reconstructed with a filtered back-projection algorithm. In order to improve image contrast and resolution in SPECT images, the rotation views were pre-processed with a Bayesean deblurring algorithm which has previously been show to offer improved contrast and resolution in planar images. SPECT images using the pre-processed rotation views were obtained and compared to the SPECT images without pre-processing and the planar images. TMJ arthropathy involving either the glenoid fossa or the mandibular condyle, orthopedic changes involving the mandible or maxilla, localized dental pathosis, as well as changes in structures peripheral to the facial skeleton were identified. Bayesean pre-processed SPECT depicted the facial skeleton more clearly as well as providing a more obvious demonstration of the bony changes associated with craniomandibular disorders than either planar images or SPECT without pre-processing

Full Text Available Iron abnormalities in chronic liver disease may be the result of genetic diseases or secondary factors. The present study aimed to identify subjects with HFE-HH in order to describe the frequency of clinical manifestations, identify risk factors for iron elevation, and compare the iron profile of HFE-HH to other genotypes in liver disease patients. A total of 108 individuals with hepatic disease, transferrin saturation (TS > 45%, and serum ferritin (SF > 350 ng/mL were tested for HFE mutations. Two groups were characterized: C282Y/C282Y or C282Y/H63D genotypes (n=16 were the HFE hereditary hemochromatosis (HFE-HH group; and C282Y and H63D single heterozygotes, the H63D/H63D genotype, and wild-type were considered group 2 (n=92. Nonalcoholic liver disease, alcoholism, and chronic hepatitis C were detected more frequently in group 2, whereas arthropathy, hepatocarcinoma, diabetes, and osteoporosis rates were significantly higher in the HFE-HH group. TS > 82%, SF > 2685 ng/mL, and serum iron > 178 μg/dL were the cutoffs for diagnosis of HFE-HH in patients with liver disease. Thus, in non-Caucasian populations with chronic liver disease, HFE-HH diagnosis is more predictable in those with iron levels higher than those proposed in current guidelines for the general population.

Reverse total shoulder arthroplasty (RSA) is a recent concept that enables good functional outcomes in cases of massive rotator cuff tear and cuff tear arthropathy. Design parameters influence the functional results and complications. The purpose of this study is to present the results of a novel RSA, the Total Evolutive Shoulder System (TESS; Biomet, Warsaw, IN, USA), based on a reverse corolla without a stem. We enrolled 101 patients with 105 RSAs in a prospective study, with a minimum follow-up period of 24 months. The analysis concerned 91 RSAs in 87 patients (61 men and 26 women), with a mean age of 73 years, at a mean follow-up of 41 months (range, 24-69 months). Ninety-six percent of patients rated their satisfaction as good or excellent. Mean flexion was 143° (range, 90°-170°), and mean external rotation was 39° (range, 20°-70°). The Constant score improved from 40 points preoperatively to 68 points at last follow-up (P TESS RSA provided encouraging midterm results with favorable outcomes and a low rate of complications. The stemless TESS with a reverse corolla is a reliable, less invasive system. Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc.

Purpose: To evaluate the diagnostic accuracy and indications of arthrography with Multidetector Computed Tomography (arthro-MDCT) of the wrist in patients with absolute or relative contraindications to magnetic resonance imaging (MRI) studies and in patients with periarticular metal implants using diagnostic arthroscopy as the gold standard. Materials and methods: After intra-articular injection of iodixanol and volumetric acquisition, 43 wrists in patients of both genders (18 females, 25 males, age range 32-60 years) were examined with a 16-detector-row CT scanner. Fifteen patients had prior wrist surgery. The patients had arthralgia, degenerative and traumatic arthropathies as well as limited range of motion, but no radiologically detected fractures. All examinations were interpreted by two experienced musculoskeletal radiologists. The findings were compared with arthroscopic findings carried out within 28 days of the CT study. Results: In non-operated and operated wrists the comparison between arthro-MDCT and arthroscopy showed sensitivity, specificity and accuracy ranging between 92% and 94% for triangular fibrocartilage complex (TFCC), between 80% and 100% for intrinsic ligaments located within the proximal carpal compartment, and between 94% and 100% for articular cartilage. Inter-observer agreement between two radiologists, in the evaluation of all types of lesions, was almost perfect (k = 0.96) and statistically significant (p < 0.05). Conclusions: Arthro-MDCT of the wrist provides an accurate diagnosis to identify chondral, fibrocartilaginous and intra-articular ligament lesions in patients who cannot be evaluated by MRI, and in post-surgical patients.

Relevant analyses were carried out on the basis of the data of 100 patients. The radiopharmaceutical examinations were performed using a scanner two hours after injection of 10 mCi 99mTc-MDP. Following interpretation of the density patterns, the concentration quotients of the scintiscans were calculated to permit a semi-quantitative assessment to be made. As far as arthropathies were concerned, the scintiscans did not contribute much useful information to diagnose patellar chondropathy at an early stage of the disease, nor were they seen to offer any decisive advantages over X-ray examinations in degenerative disorders of the joints. Scintiscanning was also found an unsuitable method to differentiate athritis from arthrosis. Under certain circumstances, joint scintiscanning may have an additional indication in the diagnosis of meniscitis. In rheumatoid arthritis and Sudeck's syndrome the scintiscans were found to be in better agreement with the clinical symptoms than the corresponding X-ray findings. In soft tissue disorders scintiscanning did not appear to be an adequate method to obtain additional diagnostic information. On the other hand, all types of osteopathy caused by inflammation, necrosis, neoplasms or cysts are clearly falling within the domaine of scintiscanning. Foot deformities were invariably seen to be associated with locallised concentration of the tracer substance. Owing to the limited specifity of radiopharmaceutical investigations using 99mTc-MDP, concentional X-ray examinations will indispensable in the vast majority of cases. (TRV) [de

Polysynovitis in a horse due to [i]Borrelia burgdorferi[/i] sensu lato infection – Case study

2015-05-01

Full Text Available Lyme borreliosis (LB is a multi-systemic tick-borne disease affecting both humans and animals, including horses, and is caused by a group of interrelated spirochetes classified within the[i] Borrelia burgdorferi [/i]sensu lato (s.l. complex. Despite the high reported seroprevalence in the European equine population for [i]B. burgdorferi[/i] s.l., to-date no documented clinical cases have been described. A 6-year-old Paint gelding was referred with a history of three weeks of fever, intermittent lameness and digital flexor tendon sheath effusion of the right hind limb. Based on a strict diagnostic protocol, which included serological tests for infectious diseases and molecular investigations, a final diagnosis was made of polysynovitis due to [i]B. burgdorferi [/i]s.l. infection. An unreported aspect observed in this case was the absence of the pathogen DNA in two of the affected joints. To the authors’ knowledge, the case described represents the first documented clinical case of equine LB in Italy. Moreover, the absence of pathogen DNA in two of the affected joints observed in this case revealed a possible similarity with the same condition described in humans, where an immunomediated pathogenesis for arthropathy due to [i]B. burgdorferi[/i] s.l. infection is suspected. Since humans and horses share the same habitat, this report supports the role of the horse as potential sentinel for human biological risk.

To evaluate stifle joints of dogs for synovitis, before development of joint instability and cranial cruciate ligament rupture (CrCLR). Cross-sectional study. Dogs (n = 16) with CrCLR and stable contralateral stifles; 10 control dogs with intact CrCL. Arthritis and tibial translation were graded radiographically. Synovitis severity and cruciate pathology were assessed arthroscopically. Presence of inflammatory cells in synovial membrane biopsies was scored histologically. CrCLR stifle pairs and control stifles were compared. Radiographic evidence of arthritis, cranial tibial translation, and arthroscopic synovitis were increased in unstable stifles, when compared with stable contralateral stifles in CrCLR dogs (P < .05). Arthroscopic synovitis in both joints of CrCLR dogs was increased compared with controls, was correlated with radiographic arthritis (S(R) = 0.71, P < .05), and was present in all stable contralateral stifles. Arthroscopically, 75% of stable stifle joints had CrCL fiber disruption, which correlated with severity of synovitis (S(R) = 0.56, P < .05). Histologic evidence of synovitis was identified in all CrCLR dogs, but was only significantly correlated with arthroscopic observations in stable stifles (r(2) = 0.57, P < .005). Synovitis is an early feature of the CrCLR arthropathy in dogs before development of joint instability clinically. Severity of synovitis is correlated with radiographic arthritis in joints with minimal to no clinically detectable CrCL damage. © Copyright 2011 by The American College of Veterinary Surgeons.

Health economics of treating haemophilia A with inhibitors.

Science.gov (United States)

Knight, C

2005-11-01

Haemophilia is a rare, inherited blood disorder in which blood clotting is impaired such that patients suffer from excessive internal and external bleeding. At present there is no cure for haemophilia A and patients require expensive, life-long treatment involving clotting factor replacement therapy. Treatment costs are perceived to be higher for patients who have developed inhibitory antibodies to factor VIII, the standard therapy for haemophilia A. However, initial cost analyses suggest that clotting factor therapy with alternative haemostatic agents, such as recombinant activated factor VII or activated prothrombin complex concentrate, is no more expensive for the majority of haemophilia A patients with inhibitors than for those without inhibitors. With the availability of effective alternative haemostatic agents, orthopaedic surgery for haemophilia A patients with inhibitors is now a clinical option, and initial cost analyses suggest this may be a cost-effective treatment strategy for patients with inhibitors whose quality of life (QoL) is severely impaired by joint arthropathy. In an era of finite healthcare resourcing it is important to determine whether new treatments justify higher unit costs compared with standard therapies and whether such higher costs are justified from an individual perspective in terms of improved QoL, and from a societal perspective in terms of improved productivity and reduced overall healthcare costs. This paper examines current data on the health economics of treating haemophilia A patients with inhibitors, focusing on the overall costs of clotting factor replacement therapy and the cost consequences of joint replacement.

Friction-Induced Mitochondrial Dysregulation Contributes to Joint Deterioration in Prg4 Knockout Mice

Directory of Open Access Journals (Sweden)

Kimberly A. Waller

2017-06-01

Full Text Available Deficiency of PRG4 (lubricin, the boundary lubricant in mammalian joints, contributes to increased joint friction accompanied by superficial and upper intermediate zone chondrocyte caspase-3 activation, as shown in lubricin-null (Prg4−/− mice. Caspase-3 activity appears to be reversible upon the restitution of Prg4 either endogenously in vivo, in a gene trap mouse, or as an applied lubricant in vitro. In this study we show that intra-articular injection of human PRG4 in vivo in Prg4−/− mice prevented caspase-3 activation in superficial zone chondrocytes and was associated with a modest decrease in whole joint friction measured ex vivo using a joint pendulum method. Non-lubricated Prg4−/− mouse cartilage shows caspase cascade activation caused by mitochondrial dysregulation, and significantly higher levels of peroxynitrite (ONOO− and −OH and superoxide (O−2 compared to Prg4+/+ and Prg4+/− cartilage. Enzymatic activity levels of caspase 8 across Prg4 mutant mice were not significantly different, indicating no extrinsic apoptosis pathway activation. Western blots showed caspase-3 and 9 activation in Prg4−/− tissue extracts, and the appearance of nitrosylated Cys163 in the active cleft of caspase-3 which inhibits its enzymatic activity. These findings are relevant to patients at risk for arthrosis, from camptodactyl-arthropathy-coxa vara-pericarditis (CACP syndrome and transient lubricin insufficiency due to trauma and inflammation.

Reverse total shoulder glenoid baseplate stability with superior glenoid bone loss.

Martin, Elise J; Duquin, Thomas R; Ehrensberger, Mark T

2017-10-01

Superior wear of the glenoid bone is common in patients with rotator cuff arthropathy. This can become a treatment challenge for patients who require shoulder arthroplasty. In reverse shoulder arthroplasty (RSA), glenoid bone loss may affect the stability of baseplate fixation. The primary purpose of this biomechanical laboratory study was to assess the initial fixation stability of RSA glenosphere baseplates in the presence of variable amounts of superior glenoid bone loss. High-density solid rigid polyurethane foam (30 pounds/cubic foot) was machined to model the glenoid with variable superior defects that provided different levels of support (100%, 90%, 75%, and 50%) for the glenosphere baseplate. The samples were cyclically loaded (0-750 N at 1 Hz for 5000 cycles) at a 60° glenohumeral angle. The micromotion and migration of the baseplate were calculated from displacement data captured during the loading tests with an array of 3 linear variable differential transformers mounted around the baseplate. Micromotion was significantly greater in samples with 50% defects compared with those with smaller defects. Migration was significantly greater after testing for all defect sizes. Initial fixation of RSA glenosphere baseplates was significantly reduced in models with 50% bone loss on the superior edge compared with models with less bone loss in this high-density bone foam model.

Advances in the diagnosis and management of neck pain.

Science.gov (United States)

Cohen, Steven P; Hooten, W Michael

2017-08-14

Neck pain imposes a considerable personal and socioeconomic burden-it is one of the top five chronic pain conditions in terms of prevalence and years lost to disability-yet it receives a fraction of the research funding given to low back pain. Although most acute episodes resolve spontaneously, more than a third of affected people still have low grade symptoms or recurrences more than one year later, with genetics and psychosocial factors being risk factors for persistence. Nearly half of people with chronic neck pain have mixed neuropathic-nociceptive symptoms or predominantly neuropathic symptoms. Few clinical trials are dedicated solely to neck pain. Muscle relaxants and non-steroidal anti-inflammatory drugs are effective for acute neck pain, and clinical practice is mostly guided by the results of studies performed for other chronic pain conditions. Among complementary and alternative treatments, the strongest evidence is for exercise, with weaker evidence supporting massage, acupuncture, yoga, and spinal manipulation in different contexts. For cervical radiculopathy and facet arthropathy, weak evidence supports epidural steroid injections and radiofrequency denervation, respectively. Surgery is more effective than conservative treatment in the short term but not in the long term for most of these patients, and clinical observation is a reasonable strategy before surgery.

Full Text Available Rehabilitation plays an important role in the physical health of patients with hemophilia. However, comprehensive information regarding the utilization of rehabilitation for such patients remains scarce.This population-based study aimed to examine the characteristics, trends, and most important factors affecting rehabilitation usage in patients with hemophilia A using a nationwide database in Taiwan.Data from 777 patients with hemophilia A who were registered in the National Health Insurance Research Database between 1998 and 2008 were analyzed using SAS 9.0.Musculoskeletal or nervous system-related surgical procedures and clotting factor VIII concentrate costs were identified as factors affecting rehabilitation usage; musculoskeletal or nervous system-related surgical procedures (odds ratio = 3.788; P < 0.001 were the most important predictor of whether a patient with hemophilia A would use rehabilitation services. Joint disorders, arthropathies, bone and cartilage disorders, intracranial hemorrhage, and brain trauma were common diagnoses during rehabilitation use. The costs of physical therapy (physiotherapy comprised the majority (71.2% of rehabilitation therapy categories. Increasingly, rehabilitation therapy was performed at physician clinics. The total rehabilitation costs were <0.1% of the total annual medical costs.Musculoskeletal or nervous system-related surgical procedures and increased use of clotting factor VIII concentrate affect the rehabilitation utilization of patients with hemophilia A the most. The findings in this study could help clinicians comprehensively understand the rehabilitation utilization of patients with hemophilia A.

Nociception at the diabetic foot, an uncharted territory

Science.gov (United States)

Chantelau, Ernst A

2015-01-01

The diabetic foot is characterised by painless foot ulceration and/or arthropathy; it is a typical complication of painless diabetic neuropathy. Neuropathy depletes the foot skin of intraepidermal nerve fibre endings of the afferent A-delta and C-fibres, which are mostly nociceptors and excitable by noxious stimuli only. However, some of them are cold or warm receptors whose functions in diabetic neuropathy have frequently been reported. Hence, it is well established by quantitative sensory testing that thermal detection thresholds at the foot skin increase during the course of painless diabetic neuropathy. Pain perception (nociception), by contrast, has rarely been studied. Recent pilot studies of pinprick pain at plantar digital skinfolds showed that the perception threshold was always above the upper limit of measurement of 512 mN (equivalent to 51.2 g) at the diabetic foot. However, deep pressure pain perception threshold at musculus abductor hallucis was beyond 1400 kPa (equivalent to 14 kg; limit of measurement) only in every fifth case. These discrepancies of pain perception between forefoot and hindfoot, and between skin and muscle, demand further study. Measuring nociception at the feet in diabetes opens promising clinical perspectives. A critical nociception threshold may be quantified (probably corresponding to a critical number of intraepidermal nerve fibre endings), beyond which the individual risk of a diabetic foot rises appreciably. Staging of diabetic neuropathy according to nociception thresholds at the feet is highly desirable as guidance to an individualised injury prevention strategy. PMID:25897350

2008-11-01

Chikungunya fever (CF) epidemic has recently re-emerged in India on a large scale affecting many parts of the country. We have reviewed the mucocutaneous manifestations of the disease in a number of cases. Twenty six serologically proven cases of CF with rash from the district of 24-Paraganas (North) in the eastern Indian state of West Bengal were subjected to detailed clinical study to investigate the chronology and evolution of mucocutaneous lesions, the type and distribution of the rash, and systemic changes. Most patients were in their 3rd and 4th decade (23% each). Males and females were equally affected. Most patients developed the rash concomitantly with the onset or during the febrile illness, but 5 (19.2%) developed rash after defervescence. Most (57.7%) patients developed rash within the first 2 days of fever. The upper limb was the most common site of first appearance of lesions. Morbilliform eruption was the most common type of lesion noted, followed by scaling, macular erythema, intertrigo, hypermelanosis, xerosis, excoriated papules, urticaria and petechial spots. Cutaneous lesions were generally asymptomatic but 5 (19.2%) patients had intense pruritus. Mucosal lesions were found in 4 (15.4%) patients. Moderate to marked joint involvement was universal. CF exanthem may have varying morphology. Since the disease is spreading widely in different parts of the world, it should be considered in the differential diagnosis of any acute febrile arthropathy with rash.

Quinolones (QNs)-induced arthropathy is an important toxic effect in immature animals leading to restriction of their therapeutic use in pediatrics. However, the exact mechanism still remains unclear. Recently, we have demonstrated that ofloxacin, a typical QN, induces apoptosis of alginate microencapsulated juvenile rabbit joint chondrocytes by disturbing the β 1 integrin functions and inactivating the ERK/MAPK signaling pathway. In this study, we extend our initial observations to further elucidate the mechanism(s) of ofloxacin-induced apoptosis by utilizing specific caspase inhibitors. Pretreatment with both caspase-9-specific inhibitor zLEHD-fmk and caspase-8 inhibitor zIETD-fmk attenuated ofloxacin-induced apoptosis and activation of caspase-3 of chondrocyte in a concentration-dependent manner, as determined by fluorescent dye staining, enzyme activity assay and immunoblotting. Furthermore, the activation of caspase-9, -8 and -3 stimulated by ofloxacin was significantly inhibited in the presence of zIETD-fmk while pretreatment with zLEHD-fmk only blocked the activation of caspase-9 and -3. Ofloxacin also stimulated a concentration-dependent translocation of cytochrome c from mitochondria into the cytosol and a decrease of mitochondrial transmembrane potential, which was completely inhibited by zIETD-fmk. In addition, ofloxacin was found to increase the level of Bax, tBid, p53 in a concentration- and time-dependent manner. Taken together, The current results indicate that the caspase-8-dependent mitochondrial pathway is primarily involved in the ofloxacin-induced apoptosis of microencapsulated juvenile rabbit joint chondrocytes

Full Text Available Spondyloepiphyseal dysplasia tarda (SEDT is a rare genetic disease in which patient suffers from short stature, short trunk and neck with disproportionately long arms, coxa vara, skeletal features such as barrel shaped chest, kyphosis, scoliosis and early arthropathy. Only limited medical and surgical management is available in modern medicine. A 15 years old male suffering from SEDT and diagnosed as Vata vyadhi was treated with Panchakarma therapy and selected Ayurvedic oral medicines. Ayurvedic treatment was directed to ameliorate the orthopaedic clinical conditions in this case. Panchakarma procedures such as Shalishastika pinda svedana for a month and Mustadi yapana basti for 16 days were given along with oral Ayurvedic medicines. Same Panchakarma procedures were repeated after an interval of 2 months. A combination of Ayurvedic oral medicines such as Trayodashanga guggulu-500 mg twice a day, Dashmool kvatha (decoction of roots of 10 herbs 40 ml twice a day, Eranda paka 10 g twice a day, Shiva gutika-500 mg twice a day and Dashmoolarista-20 ml (with equal water twice a day were prescribed. Eight scales based Medical outcome study (MOS – 36 item short form – health surveys was assessed for outcome which shows good improvement. Kyphosis, scoliosis and pain were moderately reduced. Clinical experience of this case indicates that Ayurvedic herbs along with Panchakarma can play a major role in the management of hereditary disorder SEDT.

Full Text Available Arthropathy of the distal articular surfaces of the third metacarpal (Mc3 and metatarsal (Mt3 bones in the Thoroughbred racehorse (Tb is a natural model of repetitive overload arthrosis. We describe a novel pathology that affects the articular calcified cartilage (ACC and subchondral bone (SCB and which is associated with hyaline articular cartilage degeneration. Parasagittal slices cut from the palmar quadrant of the distal condyles of the left Mc3/Mt3 of 39 trained Tbs euthanased for welfare reasons were imaged by point projection microradiography, and backscattered electron (BSE scanning electron microscopy (SEM, light microscopy, and confocal scanning light microscopy. Mechanical properties were studied by nanoindentation. Data on the horses' training and racing career were also collected. Highly mineralised projections were observed extending from cracks in the ACC mineralising front into the hyaline articular cartilage (HAC up to two-thirds the thickness of the HAC, and were associated with focal HAC surface fibrillation directly overlying their site. Nanoindentation identified this extruded matrix to be stiffer than any other mineralised phase in the specimen by a factor of two. The presence of projections was associated with a higher cartilage Mankin histology score (P < 0.02 and increased amounts of gross cartilage loss pathologically on the condyle (P < 0.02. Presence of projections was not significantly associated with: total number of racing seasons, age of horse, amount of earnings, number of days in training, total distance galloped in career, or presence of wear lines.

Full Text Available Aim: to study a sample of patients with morbid obesity who are on the waiting list for a surgical intervention, to establish various scores of surgical risk (Possum and severity score, and to assess potential criteria for list prioritization. Design: we calculated physiological and surgical Possum scores for every patient, and analysed comorbidities and other associated factors to calculate the severity score. Likewise, we calculated the predictive rates of morbimortality. Differences between associated comorbidities in body mass index (BMI were also analyzed. The correlation between Possum score, prediction rates, and severity score were analyzed. Patients: fifty-two patients on the surgical waiting list in our institution (San Juan University Hospital, Reus from 26/4/02 to 5/03/04. Results: the mean qualitative score is significantly higher in the female sex. Invalidating arthropathy and socio-occupational and/or psychiatric criteria are significantly higher in women. There is a significant correlation between the severity score and Possum score. Age does not correlate with any of the variables studied. Conclusions: possum scores are significantly related to BMI, particularly in terms of morbidity rates. The degree of correlation between the Possum score and the qualitative score tells how useful the latter is to cover other determinant factors in the severity of this condition. Socio-occupational and psychiatric criteria, and invalidating arthropathy are the main variables to be taken into account for postsurgical prediction, and are directly related to BMI degree.Objetivo: estudio de una muestra de pacientes afectos de obesidad mórbida y en lista de espera para intervención quirúrgica, determinar el riesgo quirúrgico según diferentes scores (Possum y score de gravedad y valorar los posibles criterios en la priorización de dicha lista.

To delineate the spectrum of knee injuries associated with sprains and tears of the distal iliotibial band (ITB). A retrospective review of 200 random MRI scans undertaken for acute knee trauma was performed. Scans were excluded if there was a history of injury over 4 weeks from the time of the scan, septic arthritis, inflammatory arthropathy, previous knee surgery, or significant artefact. In each scan, the ITB was scored as normal, minor sprain (grade 1), severe sprain (grade 2), and torn (grade 3). The menisci, ligaments, and tendons of each knee were also assessed. The mean age was 27.4 years (range, 9-69 years) and 71.5 % (n = 143) of the patients were male. The ITB was injured in 115 cases (57.5 %). The next most common soft tissue structure injured was the anterior cruciate ligament (ACL) in 53.5 % of cases (n = 107). Grade 1 ITB injury was seen in 90 of these 115 cases (45 %), grade 2 injury in 20 cases, and grade 3 injury in only five cases. There is a significant association between ITB injury and ACL rupture (p < 0.05), as well as acute patellar dislocation (p < 0.05). There were ten cases of significant posterolateral corner injury, and all were associated with ITB injury, including four ITB tears. Only two cases of isolated ITB injury were seen (1 %). ITB injury is common in acute knee trauma and is associated with significant internal derangement of the knee, especially cruciate ligament rupture, posterolateral corner injury, and patellar dislocation.

B19-specific T cells developed and maintained an activated CD38+ phenotype, with strong expression of perforin and CD57 and downregulation of CD28 and CD27. These cells possessed strong effector function and intact proliferative capacity. Individuals tested many years after infection exhibited lower frequencies of B19-specific cytotoxic T lymphocytes, typically 0.05%-0.5% of CD8+ T cells, which were perforin, CD38, and CCR7 low.This is the first example to our knowledge of an "acute" human viral infection inducing a persistent activated CD8+ T cell response. The likely explanation--analogous to that for cytomegalovirus infection--is that this persistent response is due to low-level antigen exposure. CD8+ T cells may contribute to the long-term control of this significant pathogen and should be considered during vaccine development.

2010-01-01

In Western countries, the treatment of patients with inhibitors is presently the most challenging and serious issue in haemophilia management, direct costs of clotting factor concentrates accounting for >98% of the highest economic burden absorbed for the healthcare of patients in this setting. Being designed to address questions of resource allocation and effectiveness, decision models are the golden standard to reliably assess the overall economic implications of haemophilia with inhibitors in terms of mortality, bleeding-related morbidity, and severity of arthropathy. However, presently, most data analyses stem from retrospective short-term evaluations, that only allow for the analysis of direct health costs. In the setting of chronic diseases, the cost-utility analysis, that takes into account the beneficial effects of a given treatment/healthcare intervention in terms of health-related quality of life, is likely to be the most appropriate approach. To calculate net benefits, the quality adjusted life year, that significantly reflects such health gain, has to be compared with specific economic impacts. Differences in data sources, in medical practice and/or in healthcare systems and costs, imply that most current pharmacoeconomic analyses are confined to a narrow healthcare payer perspective. Long-term/lifetime prospective or observational studies, devoted to a careful definition of when to start a treatment; of regimens (dose and type of product) to employ, and of inhibitor population (children/adults, low-responding/high responding inhibitors) to study, are thus urgently needed to allow for newer insights, based on reliable data sources into resource allocation, effectiveness and cost-utility analysis in the treatment of haemophiliacs with inhibitors.

Recent advances in management of alkaptonuria (invited review; best practice article).

Ranganath, Lakshminarayan R; Jarvis, Jonathan C; Gallagher, James A

2013-05-01

Alkaptonuria (AKU) is an autosomal recessive condition arising as a result of a genetic deficiency of the enzyme homogentisate 1,2 dioxygenase and characterised by accumulation of homogentisic acid (HGA). Oxidative conversion of HGA leads to production of a melanin-like polymer in a process termed ochronosis. The binding of ochronotic pigment to the connective tissues of the body leads to multisystem disorder dominated by premature severe spondylo-arthropathy. Other systemic features include stones (renal, prostatic, salivary, gall bladder), renal damage/failure, osteopenia/fractures, ruptures of tendons/muscle/ligaments, respiratory compromise, hearing loss and aortic valve disease. Detection of these features requires systematic investigation. Treatment in AKU patients is palliative and unsatisfactory. Ascorbic acid, low protein diet and physiotherapy have been tried but do not alter the underlying metabolic defect. Regular surveillance to detect and treat complications early is important. Palliative pain management is a crucial issue in AKU. Timely spinal surgery and arthroplasty are the major treatment approaches at present. A potential disease modifying drug, nitisinone, inhibits 4-hydroxy-phenyl-pyruvate-dioxygenase and decreases formation of HGA and could prevent or slow the progression of disease in AKU. If nitisinone therapy is able to complement the biochemical 'cure' with improved outcomes, it will completely alter the way we approach the management of this disease. Greater efforts to improve recognition and registration of the disease will be worthwhile. Improved laboratory diagnostics to monitor the tyrosine metabolic pathway that includes plasma metabolites including tyrosine to monitor efficacy, toxicity and safety postnitisinone will also be required.

Alkaptonuria (AKU) is an autosomal recessive disorder due to homogentisate 1,2-dioxygenase (HGD) deficiency in the liver and characterized by a triad of signs, according to chronology of appearance: homogentisic aciduria (HGA) or alkaptonuria, ochronosis then ochronotic arthropathy. This inborn error of metabolism is caused by mutations in the HGD gene. In this work we report observations of 96 AKU French patients from 81 families collected in the literature since 1882 and from our personal contribution since 1986, giving an incidence of the disease of around 1:680,000 (96/64.10(6)). As expected for an autosomal recessive disorder the main findings of this study were: a slight predominance of males (51/93, 54,8%) over females (42/93, 45,2%), a strong predominance of sibships with one affected individual (68/81, 84,0%) over sibships with two (11/81, 13.6%) and three(2/81, 2.4%) affected individuals. AKU families are scaterred among the French territory suggesting that most cases occured in non-consanguineous unions. Consanguinity was only found in five families. Other peculiarities of this study were (a) ten of these families have both parents from a foreign geographical origin: Poland(3), Italy(3), Portugal(2), Ukraine(1) and India(1) and four families with only one foreign parent (Algeria, Armenia, Serbia, UK), (b) HGD mutations were found in 23 families, (c) four of theses 96 patients were seen by us respectively 28, 29, 39 and 45 years after their report in the literature and (d) seven patients present cardiac and/or renal complications.

New and Pipeline Drugs for Gout.

Gout is the most common inflammatory arthropathy in the western world. Affecting millions and accounting for lost wages, increased health care costs, and significant disability, it remains a burden for those afflicted, their families, and the health care system. Despite the availability of a number of effective therapies, gout is often inadequately treated, and its impact on the patients overall health and well-being is underestimated by physicians and patients alike. For many decades, controlling acute flares was the priority in the management of gout. More recently, however, a deeper understanding of gout pathophysiology has resulted in a new appreciation that gout impacts the patient with consequences well beyond the episodes of acute inflammatory arthritis. Reflecting the chronic nature of the disease, gout treatment needs to be chronic as well, and aimed at reducing the underlying cause of gout-hyperuricemia-as well as the symptom of acute attacks. Therapy therefore requires both urate lowering and anti-inflammatory strategies. Unfortunately, the most commonly used urate lowering and anti-inflammatory treatments may be problematic in some gout patients, who often have multiple comorbidities that establish relative contraindications. Novel urate lowering therapies, and new medications to treat and prevent acute gouty flares, can not only improve care of the individual; they can also lead to a better discourse for the edification of those who manage and are managed for this underestimated disease. In this paper, we discuss new and pipeline drugs for acute gout, prophylactic anti-inflammatory therapies as well as urate lowering therapies.

To describe the patterns of injury associated with injury to the popliteofibular ligament injury. A retrospective review was performed of 180 MRI scans undertaken for acute knee trauma. Scans were excluded if the time of injury was over 4 weeks from the time of the scan, or if there was a history of septic arthritis, inflammatory arthropathy, previous knee surgery, or significant artefact. An agreed criterion for assessing the structures of the posterolateral ligamentous complex was defined and in each scan, the popliteofibular ligament (PFL) was scored as normal or injured. The menisci, ligaments, and tendons of each knee were also assessed. The mean age was 25.7 years (range, 9-65 years) and 72.2 % (n = 130) patients were male. The PFL was injured in 36 cases (20 %). There is a significant association between PFL injury and ACL rupture (p = 0.0001), ITB injury (p = 0.0001), PCL injury (p = 0.0373), in addition to associations with injury to other posterolateral corner structures including the lateral collateral ligament (p = 0.0001), biceps femoris tendon (p = 0.0014), and popliteus tendon (p = 0.0014). Of our series of PFL injuries, nine cases (25 %) were associated with further injuries of posterolateral corner structures and in 27 cases (75 %) the PFL was the only posterolateral corner structure torn. PFL injury is not uncommon in acute knee trauma and is associated with significant internal derangement of the knee, especially anterior cruciate ligament rupture, ITB sprain, and injury to other structures within the posterolateral corner.

We show a wide spectrum of musculoskeletal involvement in systemic lupus erythematosus (SLE) that can be detected by radiological examination. We determined the indications of different imaging techniques in the diagnosis and follow-up of this disease. We reviewed the clinical and radiological histories of 37 patients diagnosed as having SLE on the basis of serological and musculoskeletal criteria. We assessed the personal data of each patient, the association of the disease with autoimmune processes, serology, treatment and radiological findings using plain X ray, ultrasound, computed tomography (CT) and magnetic resonance (MR). Of the 37 cases reviewed, only ten presented changes in one or more of the imaging studies performed. the most common radiological finding was symmetric poly arthritis located at different sites. Other signs included avascular necrosis (late and early), inflammation and tendon and/or ligament rupture, nonerosive deforming arthropathies , soft tissue calcifications and arthritis (staphylococcal and tuberculous). A direct correlation was established between the anticardiolipin antibody titer, steroid doses and avascular necrosis. In SLE, radiologically detectable osteoarticular lesions are uncommon. Symmetric polyarthritis is the earliest lesion and that occurring most frequently. Other signs do not appear as often, with the exception of osteonecrosis, which usually occurs late. It developed early and was unusually aggressive in two youths with elevated anticardiolipin antibody titers and substantial systemic involvement in our series. The contributions of ultrasound and MR in the assessment of musculoskeletal involvement in SLE are especially relevant in the study of inflammations and tendon rupture and in the management of avascular necrosis, respectively.

Calcium pyrophosphate deposition disease: clinical manifestations

M.A. Cimmino

2012-01-01

Full Text Available Calcium pyrophosphate deposition (CPPD disease is an arthropathy caused by calcium pyrophosphate dihydrate (CPP crystal deposits in articular tissues, most commonly fibrocartilage and hyaline cartilage. According to EULAR, four different clinical presentations can be observed: 1 asymptomatic CPPD; 2 osteoarthritis (OA with CPPD; 3 acute CPP crystal arthritis; 4 chronic CPP inflammatory crystal arthritis. Acute CPP crystal arthritis is characterized by sudden onset of pain, swelling and tenderness with overlying erythema, usually in a large joint, most often the knee, wrist, shoulder, and hip. Occasionally, ligaments, tendons, bursae, bone and the spine can be involved. CPPD of the atlanto-occipital joint (crowned dens syndrome can cause periodic acute cervico-occipital pain with fever, neck stiffness and laboratory inflammatory syndrome. Chronic inflammatory arthritis is characterized by joint swelling, morning stiffness, pain, and high ESR and CRP. The relationship between OA and CPPD is still unclear. The main problem is whether such crystals are directly involved in the pathogenesis of OA or if they are the result of joint degeneration. Diagnosis is based on evaluation of history and clinical features, conventional radiology, and synovial fluid examination. Non-polarized light microscopy should be used initially to screen for CPPD crystals based upon their characteristic morphology, and compensated polarized light microscopy, showing the crystals to be weakly positive birefringent, is recommended for definitive identification, although this last pattern only occurs in about 20% of samples. The main goals of CPPD therapy are control of the acute or chronic inflammatory reaction and prevention of further episodes.

Full Text Available Objective: Evaluate the characteristics of arthritis, arthralgia and musculoskeletal pain after chemotherapy in patients with lung cancer. Materials and Methods: In this study, we evaluate the characteristics of 17 patients with joint symptoms following receiving chemotherapy for lung cancer. Demographic information of patients including sex, age, time of rheumatologic findings after starting of chemotherapy, time of improvement after starting of medication, and relevant laboratory findings for each patient. Results: A total of seventeen patients (six women with mean age 41.2 ± 5.2 years and 11 men with mean age 42.5 ± 8.2 that received standard chemotherapy for lung cancer according to stage of disease. Joint symptoms usually began about seven months after the first session of chemotherapy. Patients had an average of two tender joints and 1 hr of morning stiffness. Four patients were positive for anti-nuclear antibody, and none of patient was positive for rheumatoid factor. Non-steroidal anti-inflammatory drugs, disease modifying anti-rheumatic drugs (DMARD, corticosteroids, and venlafaxine were prescribed. Four patients did not show an improvement. Follow-up was available for all patients. 11 patients showed favorable responses, characterized by a significant decrease (more than 50% in morning stiffness, pain, and tender joint counts after a mean of three months′ treatment. Two patients had complete resolution of symptoms and did not required further medications for arthritis, arthralgia or musculoskeletal pain. Conclusion: Chemotherapy-related arthropathy in lung cancer is not uncommon. Early treatment with NSAID, DMARD, and corticosteroids is effective in the majority of patients.

The enigma of Galileo's eyesight: some novel observations on Galileo Galilei's vision and his progression to blindness.

Science.gov (United States)

Watson, Peter G

2009-01-01

Galileo Galilei became blind. Before this happened he revealed that his left eye had always had less than perfect vision. A study of his written works, his handwriting, and the originals of the portraits undertaken during his lifetime indicate that this probably was the case. These portraits suggest that his left eye tended to lose fixation and that, at the age of 60, he suffered from a mucocoele of the right frontal sinus; but these conditions would not have caused blindness. Considering the systemic diseases from which he suffered over his lifetime, he could possibly have had a long standing uveitis with secondary pupillary block glaucoma, common in those with the group of conditions classified as sero-negative arthropathies. Posterior scleritis with secondary glaucoma is less likely. If either of these were the cause, then the disease was probably triggered by a well-documented, severe acute illness as a young adult, the inflammation being localized to the eye as a result of severe recurrent conjunctival infections in his youth. The intermittent nature of the visual loss, the normal appearance of the cornea and pupils in his portraits, the absence of any evidence of inflammatory joint disease, the presence of halos, and the severe nature of the pain-combined with the high level of visual acuity in between attacks and its persistence until the last few weeks of vision means that angle-closure glaucoma must also be considered. These suggestions might be confirmed or refuted by studying his remains. Application has been made for this to be done.

To evaluate the effect of anti-TNF treatments on bone mineral density (BMD), bone remodelling markers (BRM) and receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegerin (OPG) in patients with chronic inflammatory joint diseases. A longitudinal prospective study was performed under clinical practice conditions on 31 patients diagnosed of rheumatoid arthritis, psoriatic arthropathy and ankylosing spondylitis who had received treatment with anti-TNF alpha drugs for one year. BMD, OPG and RANKL soluble form (sRANKL) were studied at the onset and end of the study. During the study (0, 3, 6, 9 and 12 month), disease activity (SDAI, BASDAI and CRP), functional capacity (HAQ, BASFI), BRM and vitamin D were studied. BMD was not modified after one year of treatment. The patients who took corticosteroids had a mean bone mass loss of 3% in the lumbar spine (±1.6, P=.02). In regards to the BRM, did not experience significant changes over the course of the study. Disease activity, both SDAI (P=.002) and BASDAI (P=.002), decreased. OPG was maintained without changes during the year of treatment while both the sRANKL (0.28±0.22, P=.013) and sRANKL/OPG ratio significantly decreased (0.04±0.03, P=.031). The patients being treated with anti-TNF did not present with a significant loss of DMO during the study (one year), at the same time experiencing an improvement in disease activity. This protection has been clearer in the responding patients. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Objective. To determine the prevalence of meniscal protrusion (i.e. location of the outer edge of a meniscus beyond the tibial articular surface), and to determine its relationship with internal derangement, joint effusion, and degenerative arthropathy. Design and patients. Sagittal and coronal MR images of 111 abnormal and 46 normal knees were evaluated for the presence of meniscal protrusion. We set 25% as the minimum amount of displacement considered abnormal because this was the smallest amount of displacement we could confidently discern. Presence of meniscal tear, anterior cruciate ligament (ACL) injury, joint effusion, or osteophytosis was also recorded. Results and conclusion. Normal examinations demonstrated protrusion of the medial meniscus in 6.5% of sagittal images and 15% of coronal images, and of the lateral meniscus in 2% and 13%, respectively. Fisher's exact test demonstrated a statistically significant difference between the normal and abnormal groups for the medial meniscus on both sagittal (P 0.2). A protruding medial meniscus was associated with effusion and osteophytosis (P 0.1). Posterior protrusion of the lateral meniscus was only associated with ACL injury (P<0.0001); protruding anterior horns and bodies of lateral menisci were not associated with any of the four abnormalities. It is concluded that the medial meniscus may occasionally protrude more than 25% of its width, but protrusion is more often due to effusion and osteophytes. Protrusion of the posterior horn of the lateral meniscus is associated with ACL insufficiency, while protrusion of the body and anterior horn of the lateral meniscus is a normal variant. (orig.).

Psoriatic arthritis (PsA) is an arthropathy associated with psoriasis, which is part of the spondyloarthropathy family, and which may present with various forms, from mono-oligoarthritis to symmetric polyarthritis mimicking rheumatoid arthritis. In longstanding disease, the symmetric polyarthritis is the most common pattern of PsA, involving the small joints of hands, feet (the involvement of which seems to be very common, ranging from 50 to 100% of patients), wrists, ankles and knees. Other common features are represented by the inflammation of enthesis and tendons. Its exact prevalence, in Italy, should be about 30% in psoriatic subjects or 0.42% when considering the general population. The aims of our study were to investigate, by US examination, the prevalence and the features of foot involvement in PsA and to describe their correlations with clinical findings. Ultrasound (US) examinations were performed using a Logiq 9 (General Electric Medical Systems, Milwaukee, WI) equipped with a multifrequency linear probe, working at 14 MHz. One hundred and eighty feet were investigated in a total of 101 patients. Prior to US assessment, all patients underwent a clinical examination by an expert rheumatologist who recorded the presence/absence of pain, tenderness (detected by palpation and/or active or passive mobilisation of the feet) and swelling. US finding indicative of metatarsophalangeal joint inflammation were obtained in 77 (76.2%) patients, while only 34 (33.7%) patients were positive to the clinical examination. This study demonstrates that US detected a higher number of inflamed joints with respect to clinical assessment in PsA patients.

We show a wide spectrum of musculoskeletal involvement in systemic lupus erythematosus (SLE) that can be detected by radiological examination. We determined the indications of different imaging techniques in the diagnosis and follow-up of this disease. We reviewed the clinical and radiological histories of 37 patients diagnosed as having SLE on the basis of serological and musculoskeletal criteria. We assessed the personal data of each patient, the association of the disease with autoimmune processes, serology, treatment and radiological findings using plain X ray, ultrasound, computed tomography (CT) and magnetic resonance (MR). Of the 37 cases reviewed, only ten presented changes in one or more of the imaging studies performed. the most common radiological finding was symmetric poly arthritis located at different sites. Other signs included avascular necrosis (late and early), inflammation and tendon and/or ligament rupture, nonerosive deforming arthropathies , soft tissue calcifications and arthritis (staphylococcal and tuberculous). A direct correlation was established between the anticardiolipin antibody titer, steroid doses and avascular necrosis. In SLE, radiologically detectable osteoarticular lesions are uncommon. Symmetric polyarthritis is the earliest lesion and that occurring most frequently. Other signs do not appear as often, with the exception of osteonecrosis, which usually occurs late. It developed early and was unusually aggressive in two youths with elevated anticardiolipin antibody titers and substantial systemic involvement in our series. The contributions of ultrasound and MR in the assessment of musculoskeletal involvement in SLE are especially relevant in the study of inflammations and tendon rupture and in the management of avascular necrosis, respectively.

Parvovirus B19 (hereafter referred to as B19) exhibits a marked tropism to human bone marrow (BM), and infection may lead to erythema infectiosum, arthropathy, hydrops fetalis, and various hematologic disorders. Recently, a distinct parvovirus isolate termed V9 with an unknown clinical spectrum was discovered. In contrast to the many studies of B19 serology and viremia, valid information on the frequency of B19 or V9 DNA in the BM of healthy individuals is limited. To develop a reference value, paired BM and serum samples from healthy subjects were tested for the presence of B19 and V9 DNA and specific antibodies. Immunoglobulin M (IgM) was not found in any of the serum samples. The prevalence of IgG showed a gradual and steady increase from 37% in children aged 1 to 5 years to 87% in people aged >50 years. When 190 well-characterized subjects were examined, B19 DNA was detected in the BM of 4 individuals (2.1%; 95% confidence interval, 0.58 to 5.3%) while none of the paired serum samples showed evidence of circulating viral DNA. V9 DNA was not found in any of the BM or serum samples. The finding of B19 DNA probably indicated a primary infection in one 7-year-old individual and reinfection or reactivation of persistent infection in the remaining three persons, aged 47 to 58 years. Serving as a benchmark for future studies, these findings are useful when interpreting epidemiologic data, performing BM transplantation, or considering clinical implications of parvovirus infection.

Full Text Available Patients with HIV infection may develop common diseases with atypical clinical features. HIV infection can change the classic clinical course of syphilis and increase the incidence of malignant syphilis. Malignant syphilis is a rare subtype of secondary syphilis that presents special clinical and histological features and has been associated with several processes characterized by variable degrees of immunosuppression. It is necessary to consider the possibility of this entity in the differential diagnoses in HIV-infected patients with cutaneous lesions. The dental surgeon (or oral surgeon is vital to the medical team for promoting the health and improving the quality of life of syphilis patients. A patient with HIV infection was referred to us for complaints of a white patch on the tongue, stinging and burning sensation on the tongue, loss of taste, and dryness of the mouth. On clinical examination, the patient was found to have a tabetic gait (the Prussian soldier gait associated with Charcot arthropathy. We also identified bilateral lesions with ulceration and exposure of the tissue that were tender, characterized by discrete necrosis. The treatment that was initiated at that time involved cleaning the area with gauze to remove all the white patches, followed by rinsing with bicarbonate in water (one teaspoon of baking soda dissolved in half a glass of water four times a day. Additionally, fluconazole (100 mg/day for 7 days was prescribed. We diagnosed secondary malignant syphilis of approximately 5 days duration. As an adjunctive therapy, we performed low-intensity laser treatment using a GaAsAl (gallium-aluminum arsenide laser at 790 nm. With this treatment there was progressive resolution of the lesions.

Full Text Available Hussain I Saba, Duc Quang Tran, JrDepartment of Medicine, University of South Florida Medical Center, Tampa, FL, USAAbstract: In the past, patients with severe hemophilia have suffered a substantially reduced quality of life with frequent bleeding episodes, disabling arthropathy, and shorter life expectancy. In addition, methods of treatment and management have been costly and time-consuming, and have placed a considerable burden on patients' physical and psychological well-being. With the advent of the on-demand therapy and prophylactic treatment paradigm, patients have been able to receive care with less interruption of daily activities. Treatments may be more challenging for hemophiliacs with inhibitors to replacement factor; however, recent advances in the use of bypassing agents and immune tolerance therapy have enabled them to aggressively manage their disease while maintaining their independence. This review focuses on the challenges of treating such a severe hemophiliac through examination of the lifetime experience of a young adult male with a severe form of congenital hemophilia A. At this stage of his life, the patient has minimal disabilities and is inhibitor-free through optimal care and strong family support. His aspiration to pursue a productive life has led him to a career in medicine. After receiving his medical degree, he pursued a specialty in the treatment of hemophilia. By assisting other hemophilia patients, he exemplifies both the rewards of persevering through episodes of bleeding and other complications and the fact that disabilities can be minimized when managed meticulously and in a timely fashion to enable a productive and dignified life.Keywords: hemophilia, quality of life, factor VIII inhibitors, hemophilia treatment center, early treatment, bypassing agent

Full Text Available Hip disorders in a pediatric population are a diagnostic challenge. The aim of the study is to assess the role of magnetic resonance imaging (MRI in the evaluation of non-traumatic hip disorders in a series of Egyptian patients and to review the literature on the most common hip conditions. Seventy two consecutive patients [40 males (55.6% and 32 females (44.4] with acute onset of hip complaints unrelated to trauma or falls were recruited. All patients underwent an initial full clinical assessment and blood tests as well as contrast enhanced MRI of both hips. The most common diagnosis in this group of Egyptian patients was transient synovitis in 29 (40.3% cases, followed by seronegative enthesopathy and arthropathy syndrome in 8 (11.1%, septic arthritis in 10 (13.9%, tuberculous arthritis in 4 (5.6%, sickle-cell disease in 7 (9.7%, complicated with septic arthritis in 3 (4.2%, transient bone marrow edema (BME in 3 (4.2%, osteomyelitis in 2 (2.8%, osteosarcoma in 2 (2.8%, sciatic nerve injury in 1 (1.4%, leukemia with BME in 1 (1.4%, coxa vara of both hips and L5/S1 facet joint ankylosis in 1 (1.4%, and a benign bone cyst in 1 (1.4%. MRI studies showed hip effusion in a total of 51 patients (70.8%, joint space narrowing in 9 (12.5%, and BME in 15(20.8%. MRI is a sensitive tool for assessing hip disorders in a pediatric population and can play an important role in both diagnosis and management of different hip disorders, irrespective of the underlying pathology.

A Brief History of IL-1 and IL-1 Ra in Rheumatology

Full Text Available The history of what, in 1979, was called interleukin-1 (IL-1, orchestrator of leukocyte inter-communication, began many years before then, initially by the observation of fever induction via the endogenous pyrogen (EP (1974 and then in rheumatology on the role in tissue destruction in rheumatoid diseases via the induction of collagenase and PGE2 in human synovial cells by a mononuclear cell factor (MCF (1977. Since then, the family has exploded to presently 11 members as well as many membrane-bound and soluble receptor forms. The discovery of a natural Interleukin-1 receptor antagonist (IL-1Ra in human biological fluids has highlighted the importance of IL-1 and IL-1Ra in human diseases. Evidence delineating its role in autoinflammatory syndromes and the elucidation of the macromolecular complex referred to as “inflammasome” have been instrumental to our understanding of the link with IL-1. At present, the IL-1blockade as therapeutic approach is crucial for many hereditary autoinflammatory diseases, as well as for adult-onset Still’s disease, crystal-induced arthropathies, certain skin diseases including neutrophil-triggered skin diseases, Behçet’s disease and deficiency of IL-1Ra and other rare fever syndromes. Its role is only marginally important in rheumatoid arthritis and is still under debate with regard to osteoarthritis, type 2 diabetes mellitus, cardiovascular diseases and cancer. This brief historical review focuses on some aspects of IL-1, mainly IL-1β and IL-Ra, in rheumatology. There are many excellent reviews focusing on the IL-1 family in general or with regard to specific diseases or biological discoveries.

Full Text Available Introduction and objective: Acute injury transiently lowers local mechanical pain thresholds at a limb. To elucidate the impact of painless (diabetic neuropathy on this post-traumatic hyperalgesia, pressure pain perception thresholds after a skeletal foot trauma were studied in consecutive persons without and with neuropathy (i.e. history of foot ulcer or Charcot arthropathy. Design and methods: A case–control study was done on 25 unselected clinical routine patients with acute unilateral foot trauma (cases: elective bone surgery; controls: sprain, toe fracture. Cases were 12 patients (11 diabetic subjects with severe painless neuropathy and chronic foot pathology. Controls were 13 non-neuropathic persons. Over 1 week after the trauma, cutaneous pressure pain perception threshold (CPPPT and deep pressure pain perception threshold (DPPPT were measured repeatedly, adjacent to the injury and at the opposite foot (pinprick stimulators, Algometer II®. Results: In the control group, post-traumatic DPPPT (but not CPPPT at the injured foot was reduced by about 15–25%. In the case group, pre- and post-operative CPPPT and DPPPT were supranormal. Although DPPPT fell post-operatively by about 15–20%, it remained always higher than the post-traumatic DPPPT in the control group: over musculus abductor hallucis 615 kPa (kilopascal versus 422 kPa, and over metatarsophalangeal joint 518 kPa versus 375 kPa (medians; case vs. control group; CPPPT did not decrease post-operatively. Conclusion: Physiological nociception and post-traumatic hyperalgesia to pressure are diminished at the foot with severe painless (diabetic neuropathy. A degree of post-traumatic hypersensitivity required to ‘pull away’ from any one, even innocuous, mechanical impact in order to avoid additional damage is, therefore, lacking.

Inherited factor VII (FVII) deficiency is a rare coagulation disorder with variable haemorrhagic manifestations. In severely affected cases spontaneous haemarthroses leading to advanced arthropathy have been observed. Such cases may require surgery. Therapeutic options for bleeding prevention in FVII deficient patients undergoing surgery comprise various FVII preparations but the use of recombinant activated factor VII (rFVIIa) seems to be the treatment of choice. To present the outcome of orthopaedic surgery under haemostatic coverage of rFVIIa administered according to the locally established treatment regimen in five adult patients with FVII baseline plasma levels below 10 IU dL(-1). Two patients required total hip replacement (THR); three had various arthroscopic procedures. Recombinant activated factor VII was administered every 8 h on day of surgery (D0) followed by every 12-24 h for the subsequent 9-14 days, depending on the type of surgery. Factor VII plasma coagulation activity (FVII:C) was determined daily with no predefined therapeutic target levels. Doses of rFVIIa on D0 ranged from 18 to 37 μg kg(-1) b.w. and on the subsequent days--from 13 to 30 μg kg(-1) b.w. Total rFVIIa dose per procedure ranged from 16 to 37.5 mg, and the total number of doses per procedure was 16-31. None of our patients developed excessive bleeding including those in whom FVII:C trough levels returned nearly to the baseline level on the first post-op day. Preliminary results demonstrate that rFVIIa administered according to our treatment regimen is an effective and safe haemostatic agent for hypoproconvertinaemia patients undergoing orthopaedic surgery. © 2012 Blackwell Publishing Ltd.

The spectrum of bleeding problems in FVII deficiency is highly variable and FVII levels and causative genetic mutations correlate poorly with the bleeding risk. Long-term prophylaxis is generally initiated in order to prevent subsequent CNS bleeding after a first event or in patients with other major/ life threatening/ frequent bleeding symptoms as gastrointestinal bleeding or hemarthrosis. However few data are available in the literature regarding FVII prophylaxis and clinical decisions cannot be based on evidence. We report the data available in the literature on FVII prophylaxis and our personal experience regarding three patients affected by severe FVII deficiency. Specific papers on long-term prophylaxis in severe FVII deficiency were identified using the database, PUBMED. The most frequent indications for long-term prophylaxis were CNS bleeding (58%), hemartrosis (15%) and GI bleeding (9%). Patients were treated with various dosages and frequency. Prophylactic treatment with 10-30U/kg (pdFVII) or 20-30mcg/kg (rFVIIa) twice or three times/weeks was described to be effective. In the literature and in our experience, prophylaxis can be considered in patients with severe FVII deficiency and severe bleeding phenotype. A dose of 10-30U/kg (pdFVII) or 20-30 microg/kg (rFVIIa) twice or three times/week is usually administrated, but dose and frequency can be tailored based on the clinical follow-up of the patients. Since hemarthrosis is a frequent manifestation, a suggestion to improve the outcomes of patients with severe FVII deficiency is to monitor joint condition in order to identify early arthropathy that could be another indication to start secondary prophylaxis. © 2015 John Wiley & Sons Ltd.

Full Text Available Introduction. Ankylosing spondilitis (AS is a disease from a group of seronegative spondyloarthropathies with the prevalence of 0.1% affecting mainly young males, which also gives sociomedical significance to the disease. Among all inflammatory arthropathies, AS is the most suitable for balneotherapy. Thermomineral water of the Niška Banja spa is homeothermic, oligomineral, alkaline, low radioactive radon water and also, in conjunction with mineral peloid, is considered to be optimal for this indication. Objective. Our aim was to investigate the effects of natural factors of the Niška Banja spa as a part of complex treatment on the indexes of mobility of the vertebral column in the patients with AS. Methods. The study enrolled 40 patients with the average age of 48.0±14.82 years and the average duration of disease of 16.9±6.42 years. Patients were treated with hydro- and peloid- otherapy during the average of 17.23±2.71 days. At the beginning and at the end of treatment, a number of indexes of spinal mobility were measured. The statistical significance of differences was calculated using the Student's t-test. Results. All of the measured indexes were better after balneotherapy reaching statistically significant differences in regard to the wall-to-occiput distance (p<0.05, the index of sagittal mobility of the cervical (p<0.05 and lumbar (p<0.005 spine. Conclusion. The application of natural factors of the Niška Banja spa during complex treatment of the patients with AS is accompanied with the objective increase of the spine mobility.

Full Text Available Introduction: MRI is a primary imaging modality in assessing chronic low backache. Many of the findings identified on MRI may not be symptomatic. Nerve root compressions, compression of cauda equina, posterior annular tear, facetal arthropathy are more likely to be symptomatic. Management of each of these pathologies vary. It is essential to identify the pathologies that can cause pain and symptoms in lumbar spondylosis. Aim: To identify the specific finding/pathology on MRI that corresponds to the clinical presentation of the patient with lumbar spondylosis. Materials and Methods: The study was done between May and December 2016 and included 100 patients who were referred for MRI of lumbosacral spine with history of debilitating backache for more than 2 weeks. After ruling out other causes, clinical evaluation of patients was done to localize leve; and type of pain. T1, T2 weighted and STIR imaging of lumbo-sacral spine was done. The images were studied to localize the pathology which most likely caused the pattern of pain the patient experienced. Results: The study included 55 ladies and 45 men. 42 people had radiculopathy. In 86% of cases, MRI helped in localizing the exact pathology responsible for the pattern of pain the patients experienced. Nerve compressions were seen in 86% of patients with radiculopathy. Among the people without radiculopathy, the cause for pain could be localized in 86%. The most common cause of pain identified was horizontal posterior annular fissure (40%. Conclusion: In a significant number of patients with chronic low backache, we can identify the specific pathology that corroborates with the clinical symptomatology of the patient. This aids in guiding specific management to provide symptomatic relief.

Alkaptonuria (AKU) is a rare inherited disease resulting from a deficiency of the enzyme homogentisate 1,2-dioxygenase which leads to the accumulation of homogentisic acid (HGA). AKU is characterized by severe cartilage degeneration, similar to that observed in osteoarthritis. Previous studies suggest that AKU is associated with alterations in cytoskeletal organization which could modulate primary cilia structure/function. This study investigated whether AKU is associated with changes in chondrocyte primary cilia and associated Hedgehog signaling which mediates cartilage degradation in osteoarthritis. Human articular chondrocytes were obtained from healthy and AKU donors. Additionally, healthy chondrocytes were treated with HGA to replicate AKU pathology (+HGA). Diseased cells exhibited shorter cilia with length reductions of 36% and 16% in AKU and +HGA chondrocytes respectively, when compared to healthy controls. Both AKU and +HGA chondrocytes demonstrated disruption of the usual cilia length regulation by actin contractility. Furthermore, the proportion of cilia with axoneme breaks and bulbous tips was increased in AKU chondrocytes consistent with defective regulation of ciliary trafficking. Distribution of the Hedgehog-related protein Arl13b along the ciliary axoneme was altered such that its localization was increased at the distal tip in AKU and +HGA chondrocytes. These changes in cilia structure/trafficking in AKU and +HGA chondrocytes were associated with a complete inability to activate Hedgehog signaling in response to exogenous ligand. Thus, we suggest that altered responsiveness to Hedgehog, as a consequence of cilia dysfunction, may be a contributing factor in the development of arthropathy highlighting the cilium as a novel target in AKU. © 2017 The Authors.

Objective Alkaptonuria (AKU) is a rare genetic disease which results in severe early onset osteoarthropathy. It has recently been shown that the subchondral interface is of key significance in disease pathogenesis. Human surgical tissues are often beyond this initial stage and there is no published murine model of pathogenesis, to study the natural history of the disease. The murine genotype exists but it has been reported not to demonstrate ochronotic osteoarthropathy consistent with the human disease. Recent anecdotal evidence of macroscopic renal ochronosis in a mouse model of tyrosinaemia led us to perform histological analysis of tissues of these mice that are known to be affected in human AKU. Design The homogentisate 1,2-dioxygenase Hgd+/−Fah−/− mouse can model either hereditary tyrosinaemia type I (HT1) or AKU depending on selection conditions. Mice having undergone Hgd reversion were sacrificed at various time points, and their tissues taken for histological analysis. Sections were stained with haematoxylin eosin (H&E) and Schmorl’s reagent. Results Early time point observations at 8 months showed no sign of macroscopic ochronosis of tissues. Macroscopic examination at 13 months revealed ochronosis of the kidneys. Microscopic analysis of the kidneys revealed large pigmented nodules displaying distinct ochre colouration. Close microscopic examination of the distal femur and proximal fibula at the subchondral junctions revealed the presence of numerous pigmented chondrocytes. Conclusions Here we present the first data showing ochronosis of tissues in a murine model of AKU. These preliminary histological observations provide a stimulus for further studies into the natural history of the disease to provide a greater understanding of this class of arthropathy.

Alkaptonuria is a rare autosomal recessive condition resulting from inability to breakdown homogentisic acid (HGA), an intermediate in tyrosine degradation. The condition has a triad of clinical features, the most damaging of which is ochronotic osteoarthropathy. HGA is elevated from birth, but pigmentation takes many years. We hypothesise that interleukins play a role in initiation and progression of ochronotic osteoarthropathy. C20/A4 cells were cultured and maintained in 9-cm petri dishes containing either HGA at 0.33 mM, a single interleukin (IL-1β, IL-6 or IL-10) at 1 ng/ml or a combination of HGA and a single interleukin. Statistical analysis of pigment deposits and cell viability was performed using analysis of variance with Newman-Keuls post-test. All cultures containing HGA showed a significant increase in pigment deposition compared to control and IL cultures alone. The cultures containing HGA and IL-6 showed a significant increase in pigment deposits compared to HGA alone. The cell viability counts across all cultures on day 10 demonstrated a significant decrease in cultures containing HGA compared to those which did not. There was no significant difference between cultures containing just HGA or those combined with an interleukin. This work demonstrates a role for cytokines present in the joint(s) in the pigmentation process, particularly IL-6, and that the presence of HGA in joint tissues appears more detrimental to chondrocytes than the presence of any of the interleukins found in response to joint injury, trauma and osteoarthritis (OA). This further supports the evidence that the arthropathy in alkaptonuria is much more severe and rapidly progressing.
