Distal extremity swelling with pitting edema in polymyalgia rheumatica. Report on nineteen cases.

OBJECTIVE: To determine the frequency and clinical characteristics of diffuse distal extremity swelling with pitting edema occurring in polymyalgia rheumatica (PMR). METHODS: Clinical features and laboratory findings were recorded for all 245 residents of Olmsted County, Minnesota who developed PMR over a 22-year period (1970-1991). Those who exhibited > or = 1 episode of diffuse distal extremity edema with pitting were selected for this study, and were evaluated further. RESULTS: Thirteen women and 6 men in this incidence cohort of PMR had > or = 1 episode of distal extremity swelling with pitting edema. Giant cell arteritis was also identified in 5 patients. In 11 patients, the swelling and edema development concurrently with proximal PMR symptoms. In 2 patients, the distal swelling was the initial manifestation, and in 6 patients, the distal symptoms developed during relapses or recurrences of PMR. Both upper and lower extremities were affected, usually in a symmetric manner. Other peripheral manifestations were also common. The distal swelling and pitting edema responded promptly to corticosteroids, and slowly or incompletely to nonsteroidal anti-inflammatory drugs; a similar response was observed in the proximal symptoms. The distal swelling appeared to represent tenosynovitis and synovitis of regional structures. CONCLUSION: Distal extremity swelling with pitting edema represents a manifestation of PMR that has not been well described in previous studies. Awareness of this finding will help facilitate the proper diagnosis and institution of appropriate therapy for this disease.

Juvenile rheumatoid arthritis affected sibpairs: extent of clinical phenotype concordance.

OBJECTIVE: To investigate the clinical phenotypes and demographic characteristics of 183 affected sibling pairs (ASPs) with juvenile rheumatoid arthritis (JRA) and to determine whether there are differences between the clinical phenotypes of the ASP cohort compared with patients with sporadic disease and whether there is greater sharing of specific clinical features within versus between sibpairs. METHODS: Details of the JRA Affected Sibpair Registry operations have been described previously. The frequencies of phenotypes in the 2 cohorts were tabulated, summary statistics were determined, and comparisons were made by chi-square test or t-test. Sibling risk, sibling risk ratios (lambda(s)), and odds ratios were calculated to assess familial aggregation of several different clinical manifestations. RESULTS: The most common onset type among the 164 nontwin ASPs was pauciarticular (65% overall). Fifty-three percent of the ASPs were concordant for pauciarticular-onset JRA; 19% were concordant for a polyarticular disease onset. Among subjects with polyarticular-onset disease, significantly more joints were involved at onset in simplex patients than in ASPs (P = 0.008). The difference in age at JRA onset within sibpairs (sibling 1 versus sibling 2) was not significantly different. ASPs developed disease at a mean real-time difference of 5.1 years apart. Familial aggregation was found for tenosynovitis (lambda(s) 29.5), leukocytosis (lambda(s) 25), rheumatoid factor (lambda(s) 11.0), anemia (lambda(s) 1.7), and antinuclear antibodies (lambda(s) 1.3). CONCLUSION: This study confirms the findings of earlier studies showing that a high proportion of ASPs overall show concordance of disease-onset type, except for the subset of patients with systemic disease, and that nontwin ASPs do not develop disease at the same point in real time. We conclude that JRA and its clinical manifestations do not differ substantially between ASPs and the simplex population. The exception is the number of affected joints at JRA onset among patients with polyarticular-onset disease. Familial aggregation of clinical features among ASPs adds strong evidence for a genetic background in this disease.

Prevalence and impact of musculoskeletal disorders of the upper limb in the general population.

OBJECTIVE: To determine the prevalence, interrelation, and impact of musculoskeletal disorders of the upper limb in the general population. METHODS: A total of 9,696 randomly selected adults of working age were surveyed in a 2-stage cross-sectional study involving a screening questionnaire and a standardized physical examination in symptomatic subjects. Age- and sex-specific prevalence rates were estimated for several musculoskeletal disorders and for nonspecific pain in the upper limbs. The overlap and impact on daily activities and healthcare utilization were explored. RESULTS: Among 6,038 first-stage responders, 3,152 reported upper limb symptoms and 1,960 were subsequently examined. Of subjects with pain, 44.8% had 1 or more specific soft-tissue disorders. Site-specific prevalence rates were as follows: shoulder tendinitis 4.5% among men and 6.1% among women; adhesive capsulitis 8.2% among men and 10.1% among women; lateral epicondylitis 1.3% among men and 1.1% among women; de Quervain's disease 0.5% among men and 1.3% among women; other tenosynovitis of the hand or wrist, 1.1% among men and 2.2% among women. Specific disorders tended to cluster (P < 0.001) in individuals, with particular overlap at the shoulder. Compared with subjects with nonspecific pain, those with specific disorders more often reported inability to perform everyday tasks (P < 0.05), consultation with a doctor (P < 0.05), and use of prescribed medication (P < 0.05). CONCLUSION: Upper limb pain is common in the general population and is often associated with physical signs suggestive of specific upper-limb disorders. These disorders have a substantial impact on physical function and use of health care.

Entrapment of the superficial branch of the radial nerve (Wartenberg's syndrome). A report of 52 cases.

We have treated 50 patients (52 cases) of entrapment of the sensory branch of the radial nerve in the forearm (Wartenberg syndrome) between January 1988 and July 1992. Conservative treatment achieved 71% excellent and good results. Operation was followed by 74% excellent and good results. The indications for each type of treatment are discussed. De Quervain's disease was associated in 50% of cases, and it is important to diagnose Wartenberg's syndrome before operating on the tenosynovitis in order to avoid unexpected postoperative complications and medicolegal problems.

Case report 610: Amyloid arthropathy of the left ankle.

In summary, a case of amyloid arthropathy of the left ankle in a 64-year-old patient with multiple myeloma is presented. The asymmetric presentation and site of deposition in the ankle were taken to be unusual. Involvement of both hips and the right shoulder was also suspected on subsequent evaluation. The patient's history and MR studies were essential in establishing the preoperative diagnosis. The extent of involvement, destruction of underlying cartilage, associated effusion and tenosynovitis were optimally defined by the MR images. The MR images also provided preoperative guidance in determining the approach and optimum site of biopsy.

Productive osseous changes about the wrist in rheumatoid arthritis.

Radiographs of 225 consecutive patients with adult-form rheumatoid arthritis were examined for evidence of productive osseous changes about the wrist. The prevalence of new bone on the ulnar styloid was 10%.. This form of new bone is probably due to overlying chronic tenosynovitis. A collar of new bone around the ulnar head is a result of degenerative change in the distal radioulnar joint. In general, productive osseous changes in rheumatoid arthritis may represent inflammatory periosteal bone formation, osteophytosis, or contact remodeling. We found no evidence of an association between diffuse idiopathic skeletal hyperostosis and extensive productive osseous changes in patients with rheumatoid arthritis.

Pristane-induced arthritis in Balb/c mice. I. Clinical and histological features of the arthropathy.

Intraperitoneal injection of pristane induced a clinical peripheral arthritis and/or tenosynovitis in 40% of 40 Balb/cJ/Ola mice. Hind paws were always affected first and fore paws were frequently involved. Involvement of knee joints was only apparent histologically. Some clinically unaffected animals and apparently uninvolved joints from arthritic mice were also shown to have a synovitis histologically. The time of onset and pattern of arthritis was variable. The development of arthritis was not related to plasmacytoma or ascites induction, which occurred in a similar percentage of mice over a similar period. The earliest change was synoviocyte hyperplasia and polymorphonuclear infiltration in the subintima. There was no obvious mononuclear cell infiltration. In the later stages there was erosion of cartilage and sclerosis of underlying bone. These features resemble the joint changes seen in osteoarthritis.

Juvenile spondyloarthropathies: clinical manifestations and medical imaging.

The spondyloarthropathies comprise four distinct entities--ankylosing spondylitis, psoriatic arthritis, the arthritis associated with inflammatory bowel disease, and Reiter's syndrome and other related forms of reactive arthritis. Although these are distinct diseases, they have a number of clinical, radiologic, and genetic characteristics in common which permit them to be classified under the unifying term "spondyloarthropathy". They are diseases of young adults, and when they present in patients under 16 years of age we refer to them as the "juvenile" spondyloarthropathies. They must be distinguished from juvenile rheumatoid arthritis, which is a totally separate entity; however the distinction may not always be obvious. Involvement of peripheral and sacroiliac joints commonly occurs in the juvenile spondyloarthropathies. The peripheral arthritis may be erosive and associated with bone apposition at the joint margins. Axial involvement is usually a late finding. Dactylitis and tenosynovitis are frequently present early on. Enthesitis, a highly specific feature, occurs much more often in the juvenile spondyloarthropathies than in the adult forms and it may be the only presenting feature. The plain radiograph is the primary and most important imaging modality for the assessment of these diseases. However, an expanding role of magnetic resonance imaging is evident.

Palmar erythema in rheumatoid arthritis.

Palmar erythema ("liver palms") was seen in 32/100 consecutive patients with classical rheumatoid arthritis and in 10/100 patients with various other internal diseases (p less than 0.001). Age of the patients, sex, duration of disease, titer of rheumatoid factor, stage of disease, erythrocyte sedimentation rate and frequency of volar tenosynovitis of the hands did not differ between patients with and those without palmar erythema. Ulnar deviation of the fingers was less common and the hemoglobin content of the blood was higher in patients with palmar erythema.

Sports injuries in school gaelic football: a study over one season.

School football injuries were studied over the seven months of one season on 150 males aged 16.94 +/- 0.82 years. Training averaged 4.13 +/- 1.47 hours per week and matches 1.84 +/- 0.60 hours per week. Mean time injured was: 0.51 +/- 1.7 days in hospital, 34.27 +/- 37.08 days off sport and 13.98 +/- 5.22 days of restricted activity. There were 136 match and 63 training injuries giving 175.98 injuries per 10000 hours of matches and 31.06 injuries per 10000 hours of training. Injuries were treated as follows: hospital 83, general practitioners 51, physiotherapists 28, no treatment 38. The most common injuries were: ankle sprain (11.6% of the total), hamstring strain (6.5%), contusion (6.5%) back strain (6%) knee sprain (5.0%), finger sprain (5.0%), other muscle strains (5.0%), fracture of the wrist (5.0%), dislocation of the finger (4.5%), overuse injury of the back (4.0%), tenosynovitis (3.5%), fracture of the ankle (3.0%). Thirteen injuries were to goal-keepers, 85 to backs, 31 to mid-field players and 70 to forwards. In 34.83% of the injuries foul play was given as the major cause. This was followed by "Lack of fitness", "Poor kit or boots" and "Previous injury" (all 11.24%). The most common minor cause was "Poor state of the pitch" (17.42% of injuries).

[Surgical treatment of carpal tunnel syndrome in pregnancy: results from 314 cases].

A total of 314 hands of patients suffering from carpal tunnel syndrome (CTS) in pregnancy or puerperium were treated by carpal tunnel release. In 53% of these cases, other members of the family were also affected, usually the mother. Ninety-seven patients were operated upon at both hands. One hundred thirty-three operations were performed during pregnancy, mostly in the last trimester, and 181 during puerperium. In four patients, the operation was performed on both hands simultaneously. There were also 12 cases of associated De Quervain's tenosynovitis and ten trigger fingers. Severe night pain and/or permanent hypoesthesia was experienced by 93% of the patients. All patients were operated on with local anesthesia and in a bloodless field. The distal motor latency was 7 +/- 1.5 ms in cases with hypoesthesia and 4.9 +/- 1.75 ms without sensory loss. Of the patients, 98% reported good or excellent results of the operation during pregnancy via questionnaires. Since symptoms are often very severe in pregnancy and puerperium and the operation is well-tolerated by pregnant women and without risk to either mother or child, we recommend surgery, especially when sensory loss is present and motor latency is more than 5 ms.

[Magnetic resonance imaging of the hand in rheumatoid arthritis. New scientific insights and practical application].

Magnetic resonance imaging (MRI) is a sensitive diagnostic modality for the detection of inflammatory changes in peripheral joints. Nevertheless, the widespread clinical use of MRI in assessing patients with early rheumatoid arthritis is still hampered by the technical complexity and higher cost of MRI compared with conventional radiography. This overview summarizes the results of recent research and gives practical tips on how to perform MRI of the hands. The authors present an MR protocol for hand imaging, discuss the pros and cons of low-field MR scanners, and outline pitfalls and artifacts. The MRI changes associated with rheumatoid arthritis such as synovitis, tenosynovitis, erosions, and bone marrow edema are described including their prognostic significance. The proven facts on the validation and grading of MR changes in rheumatoid arthritis are summarized. Finally, the role of MRI in the differential diagnosis of arthritis is critically discussed.

[Roentgen diagnosis and computerized tomography in inflammatory rheumatic diseases. Methods with a future?].

Plain-film radiography is an important and basic element in the assessment of inflammatory rheumatic diseases. Its various uses include assessment of inflammatory osseous destruction and the activity of inflammatory changes. Furthermore, the inflammatory collateral phenomena can indicate an acute clinical phase, and the articular soft tissue swelling and tenosynovitis are shown directly and indirectly very clearly. On the other hand, high-resolution computed tomography is very capable of showing cortical structures of bone complementary to MR. In some special clinical questions and anatomical regions, especially the axial skeleton, it delivers information of high specifity, partly for definitive diagnosis and partly for planning surgical procedures. The assessment of changes in the sacroiliac joints, sternoclavicular joints and craniocervical junction are domains of computed tomography.

[Differential therapy for the rheumatoid shoulder].

Despite frequent involvement, the rheumatoid shoulder is neglected in operative treatment of the upper extremities. The slow course of omarthritis, the compensation mechanism of scapulothoracic motion and neighbouring joints as well as dominating disabilities of the lower extremities and the rheumatoid hand are possible explanations. The pattern of destruction of the rheumatoid shoulder is characterized by progressive joint and soft tissue deterioration. Soft tissue involvement determines the course of the shoulder joint. The subacromial space is a common and early site for rheumatoid involvement, often leading to bursitis, tenosynovitis of the biceps tendon and rotator cuff rupture. Sonography and MRI enable the early detection of subacromial and glenohumeral pathology before deterioration is visible radiologically. Surgical intervention in patients with rheumatoid arthritis of the shoulder is based on the degree of radiological destruction according to Larsen, the natural course of the shoulder joint and the soft-tissue condition. The goals of surgery are to relieve pain, increase motion and restore shoulder function. Surgery should be carried out early in the course of the disease, thus determining the long-term prognosis and the remaining surgical options. Depending on the pattern of destruction of the rheumatoid shoulder, the options for treatment can be divided into early and late procedures.Joint-preserving surgery is indicated in the early stages of radiological destruction according to Larsen classification O-III, whereas the late stages of destruction (Larsen IV-V) require reconstructive surgery. The introduction of arthroscopic and semiarthroscopic techniques has improved the acceptance of early synovectomy for the rheumatoid shoulder, but there is still a place for open synovectomy in patients with extensive soft-tissue repair and bone-remodelling procedures. Arthroscopic and open synovectomy are supplementary and noncompetitive surgical procedures for the rheumatoid shoulder. With proceeding bone and soft-tissue destruction corresponding to Larsen stage IV and V, synovectomy is not successful and reconstructive surgery is necessary. Resection-interposition-arthroplasty (RAIP) remains a controversial alternative to arthroplasty in young patients with sufficient bone stock and a reconstructable rotator cuff. The success of cup-replacement will additionally restrict the indications for RAIP. RIAP remains a possible salvage procedure after aseptic and septic loosening of shoulder arthroplasty. Glenohumeral replacement arthroplasty has become the procedure of choice in reconstructive surgery of the shoulder. The severity of soft-tissue and bone destruction determines the choice of shoulder prosthesis. Current modular shoulder systems with increased numbers of humeral-head stem combinations are calculated to achieve a better adjustment of the soft-tissue tension and to optimize the adaptation between head geometry and the natural shape of the glenoid.The surrounding soft-tissue structure, especially the condition of the rotator cuff, is very important for the functional recovery after shoulder arthroplasty. We prefer a hemiarthroplasty of the rheumatoid shoulder joint to avoid critical glenoid fixation. Patients with irreparable rotator cuff tears and severe glenohumeral arthritis remain a difficult challenge in shoulder surgery and the ideal procedure has not yet been found.Pain relief and a modest increase in active motion are the main goals in operative treatment. Bipolar shoulder arthroplasty represents an adequate alternative to currently favoured hemiarthroplasty in patients with cuff-deficient shoulders.

Musculoskeletal disorders associated with HIV infection and AIDS. Part I: infectious musculoskeletal conditions.

The musculoskeletal system can be affected by a variety of abnormalities in association with human immunodeficiency virus (HIV) infection. Although not as common as complications involving other organ systems, such as the pulmonary and the central nervous systems, HIV-associated musculoskeletal disorders are sometimes the initial presentation of the viral illness. Knowledge of the existence and the characteristic appearance of the conditions affecting bone, joint, and muscle in HIV-infected patients is valuable to radiologists for diagnosis and to clinicians for detection and appropriate treatment. We reviewed recent literature to provide a comprehensive assessment of the HIV-associated musculoskeletal disorders, and present radiologic examples from our own collection. This article is divided into two parts. In the first part we review the infectious musculoskeletal disorders associated with HIV illness and AIDS, including cellulitis, abscesses, pyomyositis, septic bursitis, septic arthritis, osteomyelitis, and bacillary angiomatosis. We also present a comprehensive spectrum of mycobacterial infections, consisting of tuberculous spondylitis and spondylodiskitis, arthritis, osteomyelitis, and tenosynovitis, as well as infections caused by atypical mycobacteria. Part II of this review will concentrate on non-infectious musculoskeletal conditions, including rheumatic disorders and neoplasms.

Flexor carpi radialis tendinopathy: spectrum of imaging findings and association with triscaphe arthritis.

OBJECTIVE: To present the spectrum of pathology affecting the flexor carpi radialis (FCR), and its anatomical, functional and clinical relationship with conditions affecting the triscaphe or scapho-trapezium-trapezoid (STT) compartment, and particularly osteoarthritis. DESIGN: The study comprised two men and four women aged between 23 and 79 years (mean age, 49 years). Two musculoskeletal radiologists in consensus evaluated MRI findings. RESULTS: Five of the patients showed evidence of triscaphe osteoarthritis. One of the patients showed synovitis and reactive marrow edema at the triscaphe joint without more specific findings of osteoarthritis. Five patients showed evidence of FCR tenosynovitis. Partial-thickness tears were noted in three patients. Two patients showed complete discontinuity of the FCR; one of them had undergone prior tendon harvesting for interposition arthroplasty after trapezectomy. One patient showed a ganglion cyst in connection to the FCR tendon sheath. CONCLUSION: The FCR tendon courses over the volar surfaces of the scaphoid and trapezium in a separate fibro-osseous tunnel. This anatomical and functional relationship explains the coexistence of FCR tendinopathy and STT arthritis demonstrated by MR imaging.

Sonographic evaluation of digital annular pulley tears.

OBJECTIVE: To evaluate the sonographic (US) appearance of digital annular pulley (DAP) tears in high-level rock climbers. DESIGN AND PATIENTS: We performed a retrospective analysis of the US examinations of 16 high-level rock climbers with clinical signs of DAP lesions. MRI and surgical evaluation were performed in five and three patients respectively. The normal US and MRI appearances of DAP were evaluated in 40 and three normal fingers respectively. RESULTS: Nine of 16 patients presented a DAP tear. In eight subjects (seven with complete tears involving the fourth finger and one the fifth finger), US diagnosis was based on the indirect sign of volar bowstringing of the flexor tendons. Injured pulleys were not appreciated by US. Tears concerned the A2 and A3 in six patients and the A3 and A4 in two patients. A2 pulley thickening and hypoechogenicity compatible with a partial tear was demonstrated in one patient. MRI and surgical data correlated well with the US findings. Four patients had tenosynovitis of the flexor tendons but no evidence of pulley disruption. US examinations of three patients were normal. In the healthy subjects US demonstrated DAP in 16 of 40 digits. CONCLUSION: US can diagnose DAP tears and correlates with the MRI and surgical data. Because of its low cost and non-invasiveness we suggest US as the first imaging modality in the evaluation of injuries of the digital pulley.

Gadolinium-enhanced MR imaging of the wrist in rheumatoid arthritis: value of fat suppression pulse sequences.

OBJECTIVE: To determine the usefulness of fat-suppressed gadolinium (Gd)-enhanced MR imaging of the wrist in patients with rheumatoid arthritis (RA). DESIGN AND PATIENTS: Fat-suppressed Gd-enhanced T1-weighted spin-echo (SE) images were obtained and compared with other standard techniques in 38 wrists of 27 patients (22-77 years) with RA. Scoring based on the degree of synovial enhancement of each joint was developed and the total scores (J-score) were correlated with radiographic stage, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and symptomatic change in the follow-up study. RESULTS: Synovial proliferations showed marked enhancement in all the wrists. In addition, contrast enhancement in the bone marrow and tenosynovium was seen in 36 and eight wrists respectively. Fat-suppressed Gd-enhanced T1-weighted images demonstrated these abnormalities better than other techniques. The J-scores correlated well with values of CRP (P = 0.0034), but not with radiographic stages and ESR. CONCLUSION: Fat-suppressed Gd-enhanced T1-weighted SE images can clearly demonstrate most of the essential lesions in RA including the proliferative synovium, bone erosion, bone marrow inflammatory change, and tenosynovitis. Scoring based on the extent of Gd-enhancement of synovium can be useful in the assessment of the inflammatory status.
