Erosive spondylo-arthropathy and tertiary hyperparathyroidism.

A patient on long term haemodialysis for analgesic nephropathy, with known teriary hyperparathyroidism developed a rapidly evolving, erosive, non-infective spondylo-arthropathy at two vertebral levels. In addition, erosions were noted adjacent to the right sacroiliac joint. Subsequent postmortem material from the affected vertebral levels demonstrated changes consistent with hyperparathyroidism alone and this is suggested as the possible aetiology underlying this recently recognised destructive spondyloarthropathy.

Hydronephrosis due to ureteral endometriosis treated by transperitoneal laparoscopic ureterolysis.

Ureteral obstruction secondary to endometriosis is relatively uncommon. We present a 43-year-old multiparous woman who suffered from periodic left loin pain in the terminal period of her menstruation. Excretory urogram demonstrated left hydronephrosis and hydroureter and obstruction of the lower left ureter just inferior to the left sacroiliac joint without urolithiasis. An enhanced computed tomography scan showed soft tissue density mass around the left ureter at the level of the stenosis. She underwent transperitoneal laparoscopic ureterolysis and adhesiotomy of the left ureter under the diagnosis of ureteral endometriosis. Because blueberry spots were clearly observed on the pelvic brim, the fibrous tissue surrounded the ureter was removed with peritoneal bleeding spots. Histological examination of the surrounding tissue confirmed the ectopic endometriosis. Even though retroperitoneoscopy is frequently used for ureteral lesion, transperitoneal laparoscopy has an advantage for resection of ectopic endometriosis surrounding the ureter.

Primary choice of intervention for distal ureteric stone: ureteroscopy or ESWL?

Either transurethral ureteroscopy (URS) or extracorporeal shock wave lithotripsy (ESWL) was the primary method of intervention in two series of patients presenting consecutively with stones located in the ureter distal to the radiological marking of the sacroiliac joint. Of 65 patients treated by URS, successful evacuation of the major part of the stone was achieved in 97% in one or two sessions. Of those subsequently attending for review, 93% proved stone-free but 3% required surgery for serious complications. In the ESWL series of 53 patients, successful stone fragmentation was recorded in 94%, with 2 patients requiring a supplementary endourological or surgical procedure. No significant complications were related to ESWL and 90% of those followed up after successful ESWL proved stone-free at 6 weeks. In uncomplicated cases, the mean procedure time for ESWL was one-third of that required for URS and the hospital stay one-half. It is suggested that ESWL should be the primary method of intervention in patients with distal ureteric stone, with URS reserved for the small number that prove refractory to such treatment.

Chronic low back pain in older adults: prevalence, reliability, and validity of physical examination findings.

OBJECTIVES: To develop a structured physical examination protocol that identifies common biomechanical and soft-tissue abnormalities for older adults with chronic low back pain (CLBP) that can be used as a triage tool for healthcare providers and to test the interobserver reliability and discriminant validity of this protocol. DESIGN: Cross-sectional survey and examination. SETTING: Older adult pain clinic. PARTICIPANTS: One hundred eleven community-dwelling adults aged 60 and older with CLBP and 20 who were pain-free. MEASUREMENTS: Clinical history for demographics, pain duration, previous lumbar surgery or advanced imaging, neurogenic claudication, and imaging clinically serious symptoms. Physical examination for scoliosis, functional leg length discrepancy, pain with lumbar movement, myofascial pain (paralumbar, piriformis, tensor fasciae latae (TFL)), regional bone pain (sacroiliac joint (SIJ), hip, vertebral body), and fibromyalgia. RESULTS: Scoliosis was prevalent in those with (77.5%) and without pain (60.0%), but prevalence of SIJ pain (84% vs 5%), fibromyalgia tender points (19% vs 0%), myofascial pain (96% vs 10%), and hip pain (48% vs 0%) was significantly different between groups (P < .001). Interrater reliability was excellent for SIJ pain (0.81), number of fibromyalgia tender points (0.84), and TFL pain (0.81); good for scoliosis (0.43), kyphosis (0.66), lumbar movement pain (0.75), piriformis pain (0.71), and hip disease by internal rotation (0.56); and marginal for leg length (0.00) and paravertebral pain (0.39). CONCLUSION: Biomechanical and soft tissue pathologies are common in older adults with CLBP, and many can be assessed reliably using a brief physical examination. Their recognition may save unnecessary healthcare expenditure and patient suffering.

Chronic low back pain in older adults: What physicians know, what they think they know, and what they should be taught.

Chronic low back pain (CLBP) is a common and debilitating problem in older adults. Little exists in the literature about primary care physicians' (PCPs') knowledge of and confidence in managing this problem. A self-administered survey was mailed to PCPs in western Pennsylvania to measure knowledge of the evaluation and treatment of common contributors to CLBP in older adults, confidence in diagnosing these contributors through physical examination, and the association between confidence levels and knowledge. The survey combined items with an ordinal scale on which PCPs ranked their confidence in detecting various contributors to CLBP (e.g., fibromyalgia) using physical examination and patient vignettes followed by multiple choice questions designed to assess knowledge. One hundred fifty-three of 634 surveys were returned (24.1%). Overall, the majority of PCPs did not feel "very confident" in their ability to diagnose any of the contributors of CLBP listed (most items <40%). PCPs felt most confident in detecting scoliosis and least confident detecting myofascial pain of the piriformis muscle. There was a wide range in the number of respondents answering all questions related to a particular topic correctly (3.9% for sacroiliac joint syndrome to 70.4% for hip osteoarthritis). There was no relationship between knowledge scores and confidence ratings (P > .05 for all comparisons). The results point to a need for more PCP education about CLBP in older adults. It also suggests that accurate needs assessment should not rely on physician confidence ratings alone.

Superior cluneal nerve entrapment eight years after decubitus surgery.

BACKGROUND AND OBJECTIVE: Superior cluneal nerve (SCN) entrapment is one of the infrequent etiologies of low back pain (LBP), which is rarely diagnosed. Few clinical reports have been published in the literature. We present a case of severe LBP radiating to the ipsilateral buttock after decubitus surgery. CASE REPORT: A 62-year-old man weighing 85 kg presented to the algology department, suffering from severe LBP of 6 months duration. The pain was in the right iliac crest region with radiation to the ipsilateral buttock. After admission, his history was taken, physical examination was performed, and further evaluations were made. He was suspected of having facet and right sacroiliac joint pain. Two tender points were found 6.5 and 7.5 cm to the right of the midline over the iliac crest. Local anesthetic with corticosteroid was injected at the tender points over the right iliac crest. Five minutes after the injection, the pain dissipated. CONCLUSION: SCN entrapment should be considered in patients who suffer from LBP radiating to the iliac crest and buttock after other causes of LBP have been excluded.

Comparison of computed tomography, tangential view radiography, and conventional radiography in evaluation of canine pelvic trauma.

Thirteen dogs with fractures requiring surgical repair were evaluated by standard two-view (i.e., lateral and ventrodorsal) radiography, tangential view (ventro 20 degrees cranial-dorsocaudal [inlet] and ventro 20 degrees caudal-dorsocranial [outlet]) radiography, and computed tomography (CT). Radiographic and CT examinations were reviewed independently by the three authors, and specific anatomic sites were graded for the presence or possibility of lesions. The results of radiographic interpretations were compared to CT scan interpretations. Eighty-one percent of skeletal lesions detected by CT scans were diagnosed definitively radiographically. Differences between the interpretation of CT and radiographic examinations included abnormalities associated with soft-tissue structures (P < 0.0001), the sacroiliac joints (P = 0.02), and the acetabula (P = 0.04). Interpretation of the lateral/ventrodorsal and inlet/outlet radiographic series were not statistically different, although inlet views may be complimentary to the standard radiographic examination. Its use deserves further study. Reader variation was less on evaluation of CT examinations than radiographic examinations. CT multiplaner reformations and three-dimensional reconstructions were useful for surgical planning in seven dogs. CT scanning is superior to survey radiography in assessing skeletal and soft-tissue injuries in dogs with pelvic trauma, although all clinically significant surgical lesions were described accurately radiographically. Based on this small series, the routine CT examination of dogs with pelvic trauma may not be justifiable for diagnosis but may be advantageous for surgical planning, especially if acetabular fractures are suspected on radiographs.

Efficacy of anakinra in active ankylosing spondylitis: a clinical and magnetic resonance imaging study.

OBJECTIVE: To determine the efficacy of anakinra, an interleukin 1 receptor antagonist in active ankylosing spondylitis (AS), and to investigate the effect of anakinra treatment on spinal enthesitis/osteitis using magnetic resonance imaging (MRI). METHODS: A 3 month open label study of anakinra (100 mg subcutaneous injection daily) was carried out in nine patients with active AS who had back pain and an increased acute phase response, and who had failed to respond to at least one non-steroidal anti-inflammatory drug. Clinical assessment included the Bath AS Functional Index (BASFI), Bath AS Disease Activity Index (BASDAI), and AS Quality of Life (ASQoL) before and after treatment. Fat suppressed MRI of the spine and sacroiliac joints was performed with a 1.5 T scanner at baseline and at 3 months to determine the effect of treatment on spinal enthesitis/osteitis. RESULTS: Significant improvement was found in the BASFI (median baseline 5.88, 3 months 3.63, p = 0.021), BASDAI (median baseline 5.63, 3 months 3.48, p = 0.028), ASQoL (median baseline 12, 3 months 8, p = 0.011) and laboratory measures reflecting inflammation, with C reactive protein (median baseline 31 mg/l, 3 months 17 mg/l, p = 0.036) and erythrocyte sedimentation rate (median baseline 19 mm/1st h, 3 months 15 mm/1st h, p = 0.008) also showing significant improvement. Six patients (67%) achieved the Assessments in AS (ASAS) Working Group criteria of 20% improvement. Of the 38 regions of enthesitis/osteitis determined by MRI at baseline, 23 (61%) either improved or regressed completely. CONCLUSIONS: This open label pilot study suggests that anakinra is effective in controlling the clinical manifestations of AS. The clinical response was reflected by an improvement in MRI determined spinal enthesitis/osteitis.

Performance of various criteria sets in patients with inflammatory back pain of short duration; the Maastricht early spondyloarthritis clinic.

AIM: To describe how patients presenting with inflammatory back pain (IBP) of short duration can be classified by different sets of classification criteria for spondyloarthritis (SpA) and ankylosing spondylitis, and which clinical and imaging features are of discernible importance. METHODS: 68 patients with IBP of a maximum of 2 years' duration were included in the early spondyloarthritis cohort. Detailed history, clinical examination and imaging of sacroiliac joints by plain radiography and magnetic resonance imaging (MRI) were obtained. The Berlin criteria set for SpA that has a prominent place for MRI and human leucocyte antigen B27 was used to quantify the relative contribution of MRI in classifying SpA. RESULTS: 14 of the 68 patients had ankylosing spondylitis according to the modified New York criteria, 57 patients fulfilled the European Spondylarthropathy Study Group (ESSG) criteria for SpA, 48 patients fulfilled the Amor criteria for SpA (43 patients fulfilled both criteria sets) and 44 patients fulfilled the Berlin criteria for SpA. Only four patients did not fulfil any criteria set; 36 patients fulfilled ESSG, Amor and Berlin criteria. The 14 patients with ankylosing spondylitis fulfilled all three SpA criteria sets. CONCLUSION: Among our selected cohort of patients with early IBP, the prevalence of SpA according to three different criteria sets is high. The ESSG criteria were the most sensitive, followed by the Amor criteria and the Berlin criteria. The modified New York criteria for ankylosing spondylitis appeared to be the most specific. In this cohort, the contribution of MRI and human leucocyte antigen B27 to purely clinical criteria in making a diagnosis of axial SpA was limited.

Histocompatibility antigens in psoriatic arthritis.

Histocompatibility (HL-A) antigen typing was performed on 82 patients with psoriatic arthritis. The prevalance of HL-AB27 was increased (28%) compared with that in a control group (7-5%), and this was most marked in those with spinal changes. The prevalence in patients with sacroiliitis and syndesmophytes was 75%, with sacroiliitis alone 78%, but with syndesmophytes and normal sacroiliac joints only 36%. The overall prevalence in psoriatic spondylitis was 60%, with a prevalence of 71% in those fulfilling the New York criteria for anklosing spondylitis. The prevalence was not increased in those with only peripheral arthritis (11%). The prevalence of HLA-B13 was decreased in those with psoriatic spondylitis, though this was not statistically significant. The overall prevalence of HLA-BW17 was increased, this being particularly so in those with syndesmophytes, but values were not significant.

Post-yersinial arthritis in Cleveland, England.

Four cases of post-yersinial reactive arthritis are described. All patients presented with an acute lower limb arthropathy with features of an associated enthesopathy. Two patients had restriction of axial skeletal movements. Systemic features were prominent in three, including weight loss and malaise. Mean age of onset was 34 years. Three patients gave a history of antecedent diarrhoea within the previous month. Three patients had raised titres to Y enterocolitica type 0:3 (ranging from 1 in 320 to 1 in 2560) and one had raised titres to Y pseudotuberculosis type 2 at 1 in 640. Two of the three patients with Y enterocolitica reactive arthritis ran a chronic course with low grade arthropathy of lower limbs and back stiffness. One patient developed radiological sacroiliitis at two years, and two patients had an increased sacroiliac index, though x rays of the sacroiliac joints were normal. The patient with Y pseudotuberculosis reactive arthritis had a self limiting disease with spontaneous resolution over six months.

Long term prognosis in yersinia arthritis: clinical and serological findings.

Twenty two patients were followed up for a mean of 10.7 years after acute yersinia arthritis. Their clinical course, agglutination antibodies, antibodies against plasmid coded yersinia proteins, and laboratory parameters of inflammation were analysed. The clinical findings were unremarkable. Serum agglutinating antibodies against Yersinia enterocolitica were not found in any patient. Ten patients had no antibodies against plasmid coded bacterial proteins. Five patients showed IgG antibodies, one patient had an IgA and IgG result of questionable significance, and six patients had IgA and IgG antibodies in the immunoblot reaction. No evidence of systemic inflammation was found. The persistence of IgA or IgG antibodies, or both, did not have a discernible influence on the clinical course. The development of erosive changes in the sacroiliac joints occurred independently of yersinia infection.

Spondylodiscitis in SAPHO syndrome. A series of eight cases.

OBJECTIVE: To determine the frequency, clinical features, and radiological and bone scintigraphic changes of spondylodiscitis in patients with SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis). METHODS: The study was retrospective. Data from patients with the diagnostic criteria of SAPHO syndrome were analysed for clinical features, biological data (HLA B antigen), and pelvic and spine x rays. Spine computed tomography (CT) or magnetic resonance imaging (MRI) were also examined in some cases. RESULTS: 25 patients with a diagnosis of SAPHO were seen since 1985. Eight had spondylodiscitis. These included five with palmoplantar pustulosis, one with pustular psoriasis, one with psoriasis vulgaris, and one with chronic recurrent multifocal osteomyelitis without skin disease. The skin lesion occurred before the spondylodiscitis in four cases. Chest wall involvement was observed in four cases and sacroiliac joint lesions only in the case with osteomyelitis. HLA B27 was always negative and HLA B8 was found in four cases. Radiological findings consisted of erosive or sclerosing remodelling of endplates with a narrowed disc space; a reduced height of the vertebral body was also observed in some cases. These spinal lesions occurred in the three vertebral segments. Multiple sites of spondylodiscitis in the same patient were common. Bone scan showed mildly increased uptake and CT and MRI were useful for detecting signs of infection such as abscess. Enhanced signals on T2 weighted sequence or after injection of gadolinium were often observed. Follow up study of most of these patients suggests that the prognosis of spondylodiscitis in the SAPHO syndrome is favourable. CONCLUSIONS: Despite few description in the literature, spondylodiscitis in the SAPHO syndrome is common (32% in this series). These radiological findings are similar to the discovertebral changes of spondylodiscitis in ankylosing spondylitis, thus giving support to the relations between SAPHO syndrome and spondylarthropathies. However, this does not mean that the pathogenic mechanisms are the same in these two conditions.

Antibiotic treatment and long term prognosis of reactive arthritis.

OBJECTIVE: To evaluate whether a three month course of lymecycline has an effect on the long term prognosis of reactive arthritis (ReA). METHODS: In 1987-88 a double-blind controlled study with three month course of lymecycline/placebo was conducted. 17 of 23 patients treated at the outpatient department of Helsinki University Central Hospital volunteered to take part in a follow up study, where a physical examination were performed, and erythrocyte sedimentation rate, C reactive protein, rheumatoid factor, and radiographs of the lumbosacral spine and sacroiliac joints and of symptomatic peripheral joints were examined. RESULTS: 16/17 (94%) patients reported some kind of back pain and 10/17 (59%) peripheral joint symptoms during the follow up. Two patients had unilateral grade 1 sacroiliitis, one patient grade 4 sacroiliitis, and one patient bilateral grade 2 sacroiliitis. In one patient the disease had progressed to ankylosing spondylitis (AS), and in another to chronic spondyloarthropathy. In addition, two patients had small erosions in radiocarpal joints. No statistically significant differences were found between placebo and lymecycline groups in the development of chronic arthritis, sacroiliitis, or AS. CONCLUSION: The results of the initial study showed that long term treatment with lymecycline in patients with acute ReA decreased the duration of arthritis in those with Chlamydia trachomatis triggered ReA, but not in other patients with ReA. Ten years after the acute arthritis one patient had developed AS, and three had radiological sacroiliitis, three patients had radiological changes at peripheral joints. Long term lymecycline treatment did not change the natural history of the disease.

HLA-B27-associated acute anterior uveitis in the University Referral Centre in North Thailand: clinical presentation and visual prognosis.

BACKGROUND: Acute anterior uveitis (AAU) is the most frequent type of uveitis encountered in the west. Although human leucocyte antigen (HLA)-B27-associated ankylosing spondylitis was reported in South East Asia, it is not known whether HLA-B27-associated ocular disease is prevalent in Thailand. METHODS: A prospective study of 100 unrelated blood donors and 121 consecutive patients with AAU was carried out. All people underwent HLA-B27 typing and full ocular examination. Radiological examination of the sacroiliac joints was conducted in patients with low back pain or arthralgias. RESULTS: The prevalence of HLA-B27 was 10% among the blood donors in contrast with 44% in the AAU group (p<0.001). The clinical characteristics of HLA-B27-associated AAU were similar to those published throughout the world (unilaterality in 74%, hypopyon in 31%, recurrent AAU in 64%). However, the increased intraocular pressure (IOP) was more common in the HLA-B-27-negative group (p = 0.03) than in their HLA-B27-positive counterparts. At least 15% of the HLA B27-positive group had radiological signs of ankylosing spondylitis. CONCLUSION: The prevalence of HLA-B27 in the population without uveitis in Thailand is about 10% and clinical characteristics of HLA-B27-positive AAU are similar to those reported in the west. In contrast with earlier reports, HLA-B27-negative AAU in Thailand was associated with increased IOP and should be further studied.

Early-onset gouty arthritis.

Five cases of early-onset gouty arthritis are presented, with roentgenographic abnormalities evident in the first two decades of life. Three patients suffered from "primary" gout; classification of the other two patients was difficlut because of associated mental retardation, hypothyroidism and psoriasis. Radiographic alterations included soft-tissue masses and calcification, with typical erosive abnormalities and predilection for the hands and feet. The sacroiliac joints were abnormal in two patients.

Radiation-induced changes in bone.

Radiation therapy has important applications in curative, adjuvant, and palliative therapy for a wide range of malignant conditions. Evidence of radiation therapy may be seen on radiologic images obtained subsequent to therapy. Bone growth disturbances may be observed in the immature axial or appendicular skeleton. Complications in the mature skeleton include osteoradionecrosis, pathologic fracture, and radiation-induced neoplasms. Radiologic features of mandibular osteoradionecrosis include ill-defined cortical destruction without sequestration. In osteoradionecrosis of the ribs, clavicle, scapula, and humerus, radiography may demonstrate osteopenia, disorganization and coarsening of trabecular architecture, and cortical irregularity; computed tomography more clearly depicts subtle fractures, alterations in bone architecture, and dystrophic soft-tissue calcification. In osteoradionecrosis of the spine, hematopoietic cellular elements of the spinal marrow are replaced with fat, which has high signal intensity on T1-weighted magnetic resonance images and intermediate signal intensity on T2-weighted images. Radiation-induced changes in the pelvis include osteopenia, increased bone density, and widening and irregularity of the sacroiliac joints. Radiation-induced osteochondromas are radiographically identical to those that arise spontaneously. Radiographic findings in radiation-induced sarcoma demonstrate an aggressive pattern of bone destruction. Awareness of the varied radiographic manifestations of radiation-induced changes in bone and correlation with clinical features and the radiation field will usually allow distinction of these changes from those associated with other pathologic conditions.

Radiographic features of osseous metastases of soft-tissue sarcomas.

In contrast to most other neoplastic processes of bone, in our study osseous metastases from soft-tissue sarcomas (STS) were more reliably detected by radiography than by scintigraphy. The radiographic manifestations of 65 skeletal metastases in 23 patients with STS were reviewed. Although most metastases (88%) were osteolytic, eight (12%) lesions were osteoblastic. The destructive patterns were geographic in 29%, moth-eaten in 55%, and permeative in 12% of the lesions. The axial skeleton was most commonly involved. In the long bones the diaphyses were the predominant sites of involvement. The bony cortex was frequently breached, with resultant soft-tissue swelling and pathologic fractures. Noteworthy features included subarticular location, involvement of the sacroiliac joint, and an expansile appearance.
