Abstract
It is well recognized that many if not most children and adolescents attending paediatric rheumatology clinics will have a non-inflammatory origin for their complaints or disorder. Mechanical causes are frequently identified, and hypermobility or ligamentous laxity of joints is increasingly recognized as an aetiological factor in the presentation. Such conditions include 'growing pains', recurrent lower-limb arthralgia, anterior knee pain syndromes, and back pain. Studies of significant cohorts of such patients have now been published supporting the link of ligamentous laxity to particular symptom complexes. However, much disagreement remains as to the validity of hypermobility as an aetiogical factor. What seems clear is that not all hypermobile individuals will be symptomatic or indeed possibly have any risk for specific musculoskeletal disorders in later life. Screening tools such as the Beighton score are likely to be inadequate in many paediatric populations. Along with increasing recognition of these disorders in childhood and adolescence has been the development of a multidisciplinary management approach, which usually involves predominantly allied health professionals such as podiatrists, physiotherapists and occupational therapists. The challenge remains to interpret symptoms correctly as being related to the hypermobility and to predict why such children become symptomatic. The answer is likely to involve physiological and psychosocial factors. In addition, early identification and modification of risk factors may have major implications for subsequent prevalence of many adult medical disorders such as low back pain, chronic pain syndromes and degenerative osteoarthritis.

Abstract
OBJECTIVES To identify epidemiological, clinical and laboratory characteristics of juvenile dermatomyositis (JDM) in a national multi-centre cohort of patients, and to review recent changes in the understanding of management and prognosis in the light of these data. METHODS All children with idiopathic inflammatory myositis recruited to the Juvenile Dermatomyositis National Registry and Repository (UK and Ireland) were included. Features at presentation, and later in disease, were assessed and evaluated. A total of 63 out of 175 children with a new diagnosis of myositis were recruited at the time of diagnosis and followed prospectively. Out of the 175 children, 122 diagnosed prior to 2000 were recruited retrospectively, with subsequent data collected prospectively. RESULTS One patient died (0.7%), which is equivalent to one death per 465 patient years. Data were available at the time of analysis on 151 registered patients. The most common presenting features were characteristic rash, weakness, tiredness, Gottron's patches and myalgia. Muscle biopsy, magnetic resonance imaging and muscle enzymes were frequently, but not always, abnormal. Muscle enzymes and erythrocyte sedimentation rate were not useful markers of disease activity. CONCLUSIONS The JDM National Registry and Repository captures data on a significant cohort of children with inflammatory myositis. The current study reports the largest European cohort of children with dermatomyositis to date. This powerful resource will help improve our understanding of this rare disease. Prospective data collection will allow a fuller analysis of poor prognostic features, impact of therapy, and variable outcome of childhood myositis.

Abstract
Children with Philadelphia chromosome positive (Ph+) acute lymphocytic leukemia (ALL) have only a 20% event-free survival when treated with chemotherapy alone. Bone marrow transplant (BMT) for patients with matched siblings has been associated with significantly better long-term survival. We asked whether children who lack a matched sibling donor would do as well if an alternative donor was utilized. Between 1987 and 2002, we transplanted 29 children and adolescents using either an unrelated donor (23) or a mismatched family member (six). The conditioning regimen included cytosine-arabinoside, cyclophosphamide and total body irradiation. Graft-versus-host disease (GVHD) prophylaxis consisted of T-cell depletion (antibody T10B9 or OKT3 and complement) with post transplant cyclosporine (CSA). All patients engrafted. Four developed grades III-IV acute GVHD. Three of 24 evaluable patients developed extensive chronic GVHD. Two patients died of relapse (7%). Two long-term survivors (>6 years) died of malignant glioblastoma multiforme. Event-free survival at 3, 5, and 10 years is 56, 51, and 46%, respectively. Five of six patients in >CR2 or relapse at the time of transplant died. Our data should encourage the use of alternative donor transplants early in the course of disease for children with Ph+ ALL.

Abstract
OBJECTIVE To investigate the short-term effects of exercise on muscle inflammation in children with juvenile dermatomyositis (juvenile DM). Magnetic resonance imaging (MRI), muscle strength, and blood parameters were used as outcome measures. METHODS Children with active juvenile DM, inactive juvenile DM, and healthy children were assessed for muscle strength (using myometry) and function, and MRI T2-weighted relaxation time measurement; blood was obtained from patients with juvenile DM. A standardized physiotherapy-led exercise program was completed, and the MRI was performed immediately afterwards. All children were reassessed with myometry and MRI at 30 minutes and 60 minutes, and repeat blood tests were performed at 60 minutes for the patients with juvenile DM. RESULTS Ten children with active juvenile DM, 10 with inactive juvenile DM, and 20 healthy controls completed the study. Muscle inflammation assessed by MRI, myometry, and blood parameters did not change significantly in response to exercise either immediately after or up to 60 minutes after the exercise program in any group. CONCLUSION In the short term, a single bout of exercise does not change the degree of inflammation within the muscles of children with active or inactive juvenile DM or in healthy children. The data suggest that, at least in this time period, there is no evidence that exercise increases the inflammation within the muscles. We propose therefore that a moderate exercise program is safe for children with juvenile DM.

Abstract
OBJECTIVES Joint hypermobility (JH) or "ligamentous laxity" is felt to be an underlying risk factor for many types of musculoskeletal presentation in paediatrics, and joint hypermobility syndrome (JHS) describes such disorders where symptoms become chronic, often more generalized and associated with functional impairment. Clinical features are felt to have much in common with more severe disorders, including Ehlers-Danlos syndrome (EDS), osteogenesis imperfecta and Marfan syndrome, although this has not been formally studied in children. We defined the clinical characteristics of all patients with joint hypermobility-related presentations seen from 1999 to 2002 in a tertiary referral paediatric rheumatology unit. METHODS Patients were identified and recruited from paediatric rheumatology clinic and ward, and a dedicated paediatric rheumatology hypermobility clinic at Great Ormond Street Hospital. Data were collected retrospectively on the patients from the paediatric rheumatology clinics (1999-2002) and prospectively on patients seen in the hypermobility clinic (2000-2002). Specifically, historical details of developmental milestones, musculoskeletal or soft tissue diagnoses and symptoms, and significant past medical history were recorded. Examination features sought included measurements of joint and soft tissue laxity, and associated conditions such as scoliosis, dysmorphic features, cardiac murmurs and eye problems. RESULTS One hundred and twenty-five children (64 females) were included on whom sufficient clinical data could be identified and who had clinical problems ascribed to JH present for longer than 3 months. Sixty-four were from the paediatric rheumatology clinic and 61 from the hypermobility clinic. No differences were found in any of the measures between the two populations and results are presented in a combined fashion. Three-quarters of referrals came from paediatricians and general practitioners but in only 10% was hypermobility recognized as a possible cause of joint complaint. The average age at onset of symptoms was 6.2 yr and age at diagnosis 9.0 yr, indicating a 2- to 3-yr delay in diagnosis. The major presenting complaint was arthralgia in 74%, abnormal gait in 10%, apparent joint deformity in 10% and back pain in 6%. Mean age at first walking was 15.0 months; 48% were considered "clumsy" and 36% as having poor coordination in early childhood. Twelve per cent had "clicky" hips at birth and 4% actual congenital dislocatable hip. Urinary tract infections were present in 13 and 6% of the female and male cases, respectively. Thirteen and 14%, respectively, had speech and learning difficulties diagnosed. A history of recurrent joint sprains was seen in 20% and actual subluxation/dislocation of joints in 10%. Forty per cent had experienced problems with handwriting tasks, 48% had major limitations of school-based physical education activities, 67% other physical activities and 41% had missed significant periods of schooling because of symptoms. Forty-three per cent described a history of easy bruising. Examination revealed that 94% scored > or =4/9 on the Beighton scale for generalized hypermobility, with knees (92%), elbows (87%), wrists (82%), hand metacarpophalangeal joints (79%), and ankles (75%) being most frequently involved. CONCLUSIONS JHS is poorly recognized in children with a long delay in the time to diagnosis. Although there is a referral bias towards joint symptoms, a surprisingly large proportion is associated with significant neuromuscular and motor development problems. Our patients with JHS also show many overlap features with genetic disorders such as EDS and Marfan syndrome. The delay in diagnosis results in poor control of pain and disruption of normal home life, schooling and physical activities. Knowledge of the diagnosis and simple interventions are likely to be highly effective in reducing the morbidity and cost to the health and social services.

Abstract
BACKGROUND Isolated hip disease in the context of chronic childhood inflammatory arthritis is uncommon. This paper reports 14 children who presented to the rheumatology and orthopaedic departments of our hospitals with severe hip symptoms, and who continued to have primarily hip disease throughout their clinical course. Our aim was to characterize and present the relevant demographic, clinical, investigational, treatment and outcome data from the above cohort. METHODS All paediatric cases with the diagnosis of protrusio acetabuli, Otto pelvis or idiopathic chondrolysis who were seen in the past 15 yr at Great Ormond Hospital and Middlesex Hospital in London were identified and their case notes were searched retrospectively for relevant information. RESULTS In 11 cases, the disease progressed to involve no joints other than the contralateral hip. None were considered to have a specific subtype of juvenile idiopathic arthritis (JIA) and all tested were negative for HLA-B27. Elevation of serum inflammatory markers was variable. Protrusio acetabuli was the predominant radiological feature. There were definite inflammatory changes on the gadolinium-enhanced magnetic resonance imaging study in all patients who had this procedure performed (seven cases). Microbiological investigations were all consistently negative. Severe hip disease resulted in considerable ongoing symptoms and disability. Six cases were treated with disease-modifying anti-rheumatic drugs. Total hip replacement has been required in four patients to date, with major functional improvement. CONCLUSIONS These cases represent severe and disabling primary hip disease with considerable clinical and investigational inflammatory features. Such a mode of presentation has not been described previously in the context of childhood chronic inflammatory arthritides, and may represent a separate oligoarthritis subtype of JIA.

Abstract
OBJECTIVE s. To estimate dental disease indices and temporomandibular joint (TMJ) dysfunction in children with juvenile idiopathic arthritis (JIA). METHODS Indices were recorded for dental caries, bacterial dental plaque, gingival inflammation, and TMJ dysfunction in children with JIA and matched controls. RESULTS There was no significant difference in dental caries experience or the mean plaque score between children with JIA and controls. The mean gingivitis score for the permanent teeth only was significantly greater in the JIA children compared with the controls (p = 0.02). There was a significantly greater proportion of children with JIA with signs of both left and right TMJ dysfunction (p = 0.05, p = 0.02) and symptoms (p = 0.0001, p = 0.0001) compared with controls. CONCLUSION The low caries rate was attributed to the fact that children with JIA had received preventive dental care from an early age combined with sugar free medication.

Abstract
Survival periods vary considerably for patients with high-grade astrocytomas, and reliable prognostic markers are not currently available. We therefore investigated whether genetic losses from chromosomes 1p, 19q, 9p, or 10q were associated with survival in 89 high-grade astrocytomas using tissue microarrays (TMAs) derived from Radiation Therapy Oncology Group clinical trials. Cases included 15 anaplastic astrocytomas (AAs) and 74 glioblastomas (GBMs) selected on the basis of survival times significantly shorter or longer than the expected median. Genetic analysis was performed by TMA-fluorescence in situ hybridization (FISH) on array sections using 8 DNA probes, including those directed at 1p32, 19q13.4, 9p21 (p16/CDKN2A), and 10q (PTEN and DMBT1). Genetic status for each locus was correlated with patient survival group, and data were analyzed by using Fisher's exact test of association (adjusted P = 0.025). Losses of chromosome 1p, either alone or in combination with 19q, were encountered in only 2 cases, both AAs. This contrasts with oligodendrogliomas, in which combined 1p and 19q losses are frequent and predictive of prolonged survival. Solitary 19q loss was noted in 3/15 AAs and in 7/70 GBMs and was more frequent in the long-term survival group (P = 0.041, AA and GBM combined). Chromosome 9p loss was seen in 5/8 AAs and 39/57 GBMs, whereas chromosome 10q loss was detected in 4/15 AAs and 48/68 GBMs. The 9p and 10q deletions were slightly more frequent in short-term survivors, though none of the comparisons achieved statistical significance. Long-term and short-term survival groups of high-grade astrocytomas appear to have dissimilar frequencies of 19q, 9p, and 10q deletions. TMA-FISH is a rapid and efficient way of evaluating genetic alterations in such tumors.

Abstract
Over the previous three decades there have been a number of dramatic changes in our understanding of both the pathogenesis and epidemiology of the rheumatic diseases of childhood. Improvements in the classification of paediatric-onset arthritides and international collaboration in terms of multicentre research have led to the development of new therapeutic agents and better methods of outcome assessment for these chronic and often disabling conditions. Fortunately for children with paediatric rheumatic diseases treatment regimes are now available that provide excellent disease control for many and remission induction for some. Challenges include clearer definition of the genetics and pathogenesis of the diseases, delineation of reliable biological markers for diagnosis and monitoring of disease activity. The future should also herald early identification of those with a poorer prognosis, together with the design of more powerful, safer and cheaper remission-inducing agents, given to the right patients at the right time.

Abstract
OBJECTIVE The aim of the study was to examine the validity and reliability of a quantifiable measure of inflammation using magnetic resonance imaging (MRI) in children with juvenile dermatomyositis (JDM). METHODS Children with active JDM, inactive JDM and healthy children received detailed assessments of recognized measures of muscle inflammation including muscle strength (manual muscle testing and myometry) and function (Childhood Myositis Assessment Scale, Childhood Health Assessment Questionnaire), the muscle enzymes lactate dehydrogenase (LDH) and creatine kinase (CK) and T2-weighted MRI scans of the thigh muscles, and these values were correlated with each other. RESULTS Ten children with active JDM, 10 with inactive JDM and 20 healthy children completed the study. There was no significant difference in ages between the three groups. The MRI T2 relaxation times were significantly increased in active JDM compared with inactive JDM and healthy children (P = 0.05), indicating a detectable increase in inflammation within the muscles. There were also good correlations between the MRI scores and the measures of muscle strength and function; however, there was no correlation between the MRI and muscle enzymes. CONCLUSIONS The MRI T2 relaxation time can be used as a quantitative measure of muscle inflammation and it has good correlations with other measures of disease activity.

Abstract
OBJECTIVES To assess the efficacy and safety of intravenous cyclophosphamide (CYP) used in severe and refractory juvenile dermatomyositis (JDM). METHODS Retrospective case note review of the outcome of 12 patients. RESULTS Assessment at 6 months of therapy in 10 of the 12 patients showed a significant improvement in muscle function as assessed by the Childhood Myositis Assessment Scale (CMAS) (P = 0.012), muscle strength (P = 0.008), global extramuscular disease score (P = 0.008), skin disease severity (P = 0.015) and lactate dehydrogenase (P = 0.028). There were reductions in creatine kinase, alanine aminotransferase, prednisolone dose and ESR, but these did not reach statistical significance. Clinical improvement was maintained after CYP until the most recent follow-up (between 6 months and 7 yr) and no severe side-effects were seen. Reversible complications included lymphopenia, herpes zoster infections and alopecia. The median cumulative dose was 4.6 g/m(2) (range 3-9 g/m(2)). The available evidence suggests that, at the doses required, risks of malignancy, infertility and gonadal failure are low. Two patients with severe treatment-resistant disease died after one dose of CYP, both of whom were ventilated prior to commencement of CYP and were thought to have died as a result of their severe disease process, and too early for clinical benefit to be obtained from the drug. CONCLUSIONS In this cohort of children with severe and refractory JDM, CYP appeared to have provided major clinical benefit with no evidence of serious toxicity in the short term.

Abstract
OBJECTIVE To compare the safety and efficacy of parenteral methotrexate (MTX) at an intermediate dosage (15 mg/m(2)/week) versus a higher dosage (30 mg/m(2)/week) in patients with polyarticular-course juvenile idiopathic arthritis (JIA) who failed to improve while receiving standard dosages of MTX (8-12.5 mg/m(2)/week). METHODS In the screening phase, 595 patients who were newly started on a standard dose of MTX were followed up for 6 months. Subsequently, the nonresponders, defined according to the American College of Rheumatology (ACR) pediatric 30% improvement criteria (pediatric 30), were randomized to receive an intermediate dose or higher dose of parenteral MTX for an additional 6 months. Improvement in the screening and randomization phase was defined by the ACR pediatric 30 response, as well as by the 50% and 70% response levels (ACR pediatric 50 and ACR pediatric 70, respectively). RESULTS In the screening phase, after receiving standard doses of MTX, 430 patients (72%) improved according to the ACR pediatric 30, while 360 (61%) met the ACR pediatric 50 and 225 (38%) met the ACR pediatric 70; among these patients, 69 (12%) also met the definition of complete disease control. Of the 133 nonresponders, 80 were randomized to receive an intermediate dose or higher dose of MTX. In the randomization phase, the ACR pediatric 30 response rate was 25 of 40 children (62.5%) in the intermediate-dose group versus 23 of 40 children (57.5%) in the higher-dose group. An ACR pediatric 50 response rate was attained by 23 patients (57.5%) receiving an intermediate dose versus 22 (55%) in the higher-dose group. An ACR pediatric 70 response rate was seen in 18 children (45%) receiving an intermediate dose versus 19 (47.5%) receiving a higher dose. Five children (12.5%) in the intermediate-dose group versus 4 (10%) receiving the higher dose of MTX also met the definition of complete disease control. None of the intergroup differences in response rate were significant. There were no significant differences in the frequency of adverse events or laboratory abnormalities between the 2 randomized groups. CONCLUSION This study shows that the plateau of efficacy of MTX in JIA is reached with parenteral administration of 15 mg/m(2)/week and that a further increase in dosage is not associated with any additional therapeutic benefit. MTX should be administered for up to 9-12 months to appreciate its full therapeutic effect.

Abstract
OBJECTIVE To identify preliminary core sets of outcome variables for disease activity and damage assessment in juvenile systemic lupus erythematosus (JSLE) and juvenile dermatomyositis (JDM). METHODS Two questionnaire surveys were mailed to 267 physicians from 46 different countries asking each member to select and rank the response variables used when assessing clinical response in patients with JSLE or JDM. Next, 40 paediatric rheumatologists from 34 countries met and, using the nominal group technique, selected the domains to be included in the disease activity and damage core sets for JSLE and JDM. RESULTS A total of 41 response variables for JSLE and 37 response variables for JDM were selected and ranked through the questionnaire surveys. In the consensus conference, domains selected for both JSLE and JDM activity or damage core sets included the physician and parent/patient subjective assessments and a global score tool. Domains specific for JSLE activity were the immunological tests and the kidney function parameters. Concerning JDM, functional ability and muscle strength assessments were indicated for both activity and damage core sets, whereas serum muscle enzymes were included only in the activity core set. A specific paediatric domain called 'growth and development' was introduced in the disease damage core set for both diseases and the evaluation of health-related quality of life was advised in order to capture the influence of the disease on the patient lifestyle. CONCLUSIONS We developed preliminary core sets of measures for disease activity and damage assessment in JSLE and JDM. The prospective validation of the core sets is in progress.

Abstract
OBJECTIVE The aim of this study was to define the clinical utility of infrared thermography in disease activity detection in localized scleroderma (LS). METHODS We retrospectively reviewed 130 thermal images of 40 children with LS and calculated the sensitivity and specificity of thermography, comparing clinical descriptions of the lesions and contemporary thermographs. The reproducibility of thermography was calculated by using the weighted kappa coefficient to determine the level of agreement between two clinicians who reviewed the thermographs independently. RESULTS The sensitivity of thermography was 92% and specificity was 68%. Full concordance between the two clinicians was observed in 91% of lesions, with a kappa score of 0.82, implying very high reproducibility of this technique. CONCLUSION Our results demonstrate that thermography is a promising diagnostic tool when associated with clinical examination in discriminating disease activity, as long as it is applied to lesions without severe atrophy of the skin and subcutaneous fat. Further evaluation is needed to determine whether thermography can predict the future progression of lesions.

Abstract
The scleroderma disorders remain challenging conditions in pediatric rheumatology to understand pathologically and indeed for which to provide care. It is clear that much progress is being made in the clinical approach to understanding this group of group of disorders. It seems likely that the different lesions of LS may represent unique immunopathogenic mechanisms or perhaps reflect unique genetic or other characteristics of the patients themselves. To take advantage of the revolution in therapies now occurring in rheumatology it is critical that controlled clinical trials are developed with appropriate agreed upon outcome measures for both localized and systemic disease.

Abstract
The management of juvenile idiopathic arthritis (JIA) has undergone dramatic changes in the last decade with undoubtedly great benefit for many patients. In particular, more effective use of available drugs and the application of newly discovered drugs have been responsible for much of this improvement. Methotrexate is the gold standard for management of moderate to severe polyarthritis. Other disease-modifying antirheumatic drugs (DMARDs) such as sulphasalazine and cyclosporine are finding a specific role for resistant disease where they may be used in combination with methotrexate, for example. The introduction of anti-TNF agents, such as etanercept, is likely to herald a major shift to the use of biological agents in those intolerant to, or unresponsive to, standard DMARD therapy. DMARDs provide major steroid spring effect in many children with severe JIA with the hope that osteoporosis and growth failure will be reduced. More judicious use of corticosteroids and techniques such as intravenous 'pulse therapy' rather than long-term high-dose use of oral corticosteroids are also major changes. Intra-articular corticosteroids are commonly used in children with oligoarticular JIA and as a useful adjunct to DMARD therapy in children with other forms of JIA. Autologous stem cell transplantation is an exciting new development currently restricted to use in patients with very severe, resistant disease. Modifications of technique, experience and increased safety may make this a more widely applicable technique, in particular for patients with a poor prognosis, such as those with systemic JIA. Although the focus of this chapter is on drug therapy, multidisciplinary team management for children with chronic arthritis focusing on the physical, nutritional, intellectual and psychosocial wellbeing of the child will continue to be important.

Abstract
The incidence and risk factors for the development of diabetic retinopathy during a mean (SD) follow-up period of 4.6 (2.9) (range 1-12.4) years have been examined among 3424 patients (1878 males and 1546 females) with diabetes mellitus from three outpatient clinics at the University Hospital, Nottingham. The mean (SD) age of participants was 49.2 (17.9) years with a mean (SD) duration of diabetes of 7.3 (9.0) years at initial registration. Among the 3424 patients free of retinopathy at initial registration who attended the clinic at least twice in the period 1979-1992, the incidence of any retinopathy was 59.6 (57.8 male and 61.8 female) per 1000 person-years based on 15,571 person-years of follow-up. The incidence rate of retinopathy was 72% higher among insulin-treated than among non-insulin-treated noninsulin-dependent diabetes mellitus (NIDDM) clinic attenders. Using a Cox's Proportional Hazards Model for insulin-dependent diabetes (IDDM) and NIDDM (insulin and non-insulin-treated) diabetes separately, longer duration of diabetes, higher systolic blood pressure and poor metabolic control were significant independent predictors of retinopathy for all three groups. Never smoking was a significant independent predictor of retinopathy for the insulin-dependent diabetes groups. Lower body mass index, proteinuria and age were predictors of retinopathy only for non-insulin-treated NIDDM patients. Gender and creatinine had no significant independent association with retinopathy when other covariates were considered. These findings will help the identification of those patients at particular risk of retinopathy so that clinic time for screening of eyes can be appropriately focused.
