    Abstract Objective: To determine the methods of anesthesia currently being used by pediatric rheumatologists when performing intra-articular corticosteroid injections (IACI).
    Study design: A questionnaire was emailed to all members of the Childhood Arthritis & Rheumatology Research Alliance, a pediatric rheumatology research network in North America. The questionnaire consisted of 11 questions ranging from procedure technique, treatments prescribed for topical anesthesia and oral analgesia, and factors that might affect procedural pain.
    Results: Seventy-four of 161 physicians (46%) responded to the questionnaire. On average, each physician injected 33 children (median 25, range 1-160) and 43 joints (median 30, range 1-150) yearly. Local anesthesia was used in children on average >/= 8 years (range 2-16 years), with general anesthesia being more frequently used for younger children. All respondents used local anesthesia. The most commonly used methods of local anesthesia were EMLA((R) )cream plus subcutaneous lidocaine (58.8%), ethyl chloride spray only (39.7%), EMLA((R) )cream only (33.8%), subcutaneous lidocaine only (25%), and lidocaine iontophoresis only (11.8%). Buffering of the lidocaine was routinely done only 7.4% of the time.
    Conclusion: Although pediatric rheumatologists in North America perform IACI on a large number of patients each year, a wide variety of methods are used to deliver local anesthesia with no accepted standard of care. More studies are needed to determine the optimal method of local anesthesia delivery to minimize pain associated with IACI.

    Abstract Idiopathic musculoskeletal pain syndromes in children have a variety of manifestations; they can be diffuse or well localized, constant or intermittent, with or without autonomic symptoms and signs, completely incapacitating or not limiting activities, and they can tax the physician's diagnostic skill. A careful history and examination is usually all that is needed to make a diagnosis, although the differential diagnosis is large and might require laboratory and radiographic investigation. Pain and functional assessment help track the progress with therapy. Intense exercise therapy is associated with the best outcome. Psychologic issues should be evaluated to determine if further psychologic intervention is indicated. The medium-term outcome is probably good for most of these children, but the long-term prognosis is unknown. One must be aware that other manifestations of psychologic problems might emerge. By the time these children and their families see the rheumatologist they are desperate and can be frustrating to work with due to their difficulty in accepting any kind of psychologic element to the pain and its associated disability. Nevertheless, it is rewarding to help the children understand and work through their pain so they can resume normal lives.

    Abstract The antinuclear antibody test (ANA) is a much overused test in pediatrics. The ANA does have a role in serologic testing but it should be a very limited one. It is often ordered as a screening test for rheumatic illnesses in a primary care setting. However, since it has low specificity and sensitivity for most rheumatic and musculoskeletal illnesses in children, it should not be ordered as a screening test for non-specific complaints such as musculoskeletal pain. It should only be used as a diagnostic test for children with probable Systemic Lupus Erythematosus (SLE) or Mixed Connective Tissue Disease, (MCTD) and other possible overlap-like illnesses. Such children should have developed definite signs and symptoms of a disease before the ANA is ordered. This review presents data supporting these conclusions and a review of the ANA literature in adults and children.By limiting ANA testing, primary care providers can avoid needless venipuncture pain, unnecessary referrals, extra medical expenses, and most importantly, significant parental anxieties. It is best not to do the ANA test in most children but if it ordered and is positive in a low titer (<1:640), the results can be ignored if the child is otherwise well and does not have other features of a systemic illness.

    Abstract Parents of children with a chronic condition such as juvenile arthritis must cope with greater demands than those living with a healthy child. They must adopt different behaviours in order to lessen the impact on the family structure. Parental coping refers to the parent's specific cognitive and behavioural efforts to reduce or manage a demand on the family system. The aims of this study were: to describe coping in a cohort of parents of children with JIA; to determine whether quality of life is associated with parental coping; to explore whether socio-demographic factors such as child's age, family socioeconomic status and family structure are associated with parental coping. One hundred eighty-two parents caring for a child with JIA completed a postal survey at three times over a one-year period, which included the Juvenile Arthritis Quality of Life Questionnaire (JAQQ), the Coping Health Inventory for Parents (CHIP) and questionnaires describing socio-demographic characteristics. Linear mixed models were employed to analyse the association between the child's quality of life and parental coping. Mean total QoL scores (JAQQ) showed that children experienced difficulty in completing specified activities at most just below 25% of the time and results fall off slightly following the 6 month time point. Mean parental coping scores for the CHIP subscales at baseline were 38.4 +/- 9.0, 33.4 +/- 11.6, 16.5 +/- 6.1, for Maintaining Family Integration (maximum score 57), Maintaining Social Support (maximum score 54) and Understanding the Medical Situation (maximum score 24), respectively. Understanding the Medical Situation was deemed most useful. The child's QoL was associated with parental coping. Parents of children with greater psychosocial dysfunction used more coping behaviours related to Understanding the Medical Situation (beta coefficient, 0.73; 95% CI, 0.01, 1.45). These findings underscore the importance of helping parents of children with JIA better understand their child's medical situation.

    Abstract Objectives: To describe the clinical features, diagnosis, treatment and outcome of children with Kawasaki disease (KD) treated at a large tertiary care Canadian paediatric hospital and to try to identify correlations between clinical features and the development of coronary artery abnormalities.
    Methods: The charts of 176 patients diagnosed with typical, atypical or incomplete KD between 1992 and 2000 at British Columbia's Children's Hospital were reviewed.
    Results: The male to female ratio was 1.8:1. The median age was 2.5 years (range two months to 14 years), with 8% nine years or older (42% Caucasian, 43% Asian). Cases occurred steadily throughout the year. One hundred two (58%) patients had typical, 18 (10%) patients had atypical and 56 (32%) patients had incomplete KD. The median time from fever onset to first intravenous immunoglobulin (IVIG) was seven days (range two to 49 days), and treatment began within 10 days of fever onset in 134 (76%) patients. All patients received one or more doses of 2 g/kg IVIG. Forty-two (24%) patients received a second dose for nonresponsiveness, of whom 10 (6%) remained nonresponsive. Eight (5%) patients received intravenous methylprednisolone. Forty-eight (27%) patients developed coronary artery abnormalities, with 10 (6%) echogenic abnormalities, 25 (14%) dilatations and 13 (7%) aneurysms (seven giant). No patient with a normal echocardiogram at four to eight weeks developed an abnormality on subsequent study. Fourteen (8%) patients had persistent abnormalities at last follow-up (median 447 days, range 62 to 3272 days): seven dilations and seven aneurysms (six giant). Five of 13 children (39%) who developed aneurysms failed to meet diagnostic criteria for typical KD, and three of those five aneurysms were present at less than one year after diagnosis. Four of eight (50%) patients receiving intravenous methyl-prednisolone for IVIG nonresponsiveness had or developed aneurysms. One patient died.
    Conclusion: Some children diagnosed with KD who fail to meet the diagnostic description develop coronary artery abnormalities. There is a need for a more accurate means of diagnosis to more appropriately use IVIG, an expensive and increasingly scarce resource. The role of corticosteroids remains unclear and a randomized controlled clinical trial to determine their role is needed.

    Abstract Objective: Early recognition and treatment of pediatric rheumatic diseases is associated with improved outcome. We documented access to pediatric rheumatology subspecialty care for children in British Columbia (BC), Canada, referred to the pediatric rheumatology clinic at BC Children's Hospital, Vancouver.
    Methods: An audit of new patients attending the outpatient clinic from May 2006 to February 2007 was conducted. Parents completed a questionnaire through a guided interview at the initial clinic assessment. Referral dates were obtained from the referral letters. Patients were classified as having rheumatic disease, nonrheumatic disease, or a pain syndrome based on final diagnosis by a pediatric rheumatologist.
    Results: Data were collected from 124 of 203 eligible new patients. Before pediatric rheumatology assessment, a median of 3 healthcare providers were seen (range 1-11) for a median of 5 visits (range 1-39). Overall, the median time interval from symptom onset to pediatric rheumatology assessment was 268 days (range 13-4989), and the median time interval from symptom onset to referral to pediatric rheumatology was 179 days (range 3-4970). Among patients ultimately diagnosed with rheumatic diseases (n = 53), there was a median of 119 days (range 3-4970) from symptom onset to referral, and 169 days (range 31-4989) from onset to pediatric rheumatology assessment.
    Conclusion: Children and adolescents with rheumatic complaints see multiple care providers for multiple visits before referral to pediatric rheumatology, and there is often a long interval between symptom onset and this referral.

    Abstract Objective: To examine demographic and disease-related variables that affect pain in a large cohort of patients with juvenile rheumatoid arthritis (JRA).
    Methods: Selection criteria were an onset of JRA >/=5 years prior to study and age >/=8 years at the time of the study. Pain was measured by a self-administered 10-cm visual analog scale. Possible explanatory variables studied included age at study, sex, race, onset subtype, active disease duration, active joint count, and physician's global assessment (PGA).
    Results: In a multiple regression model, active disease duration, PGA, and age at study were independent predictors explaining 22% of the variation in pain scores. Stratified analyses showed an effect of age in the 8-15-year group, but not in older patients.
    Conclusion: Disease-related factors explain only a small proportion of the variation in pain scores. Age has an effect on pain scores only in younger patients. The role of other factors, including psychosocial factors, needs further study.
