Abstract
BACKGROUND To describe the demographic, clinical, and treatment characteristics of youth diagnosed with juvenile primary fibromyalgia syndrome (JPFS) who are seen in pediatric rheumatology clinics. METHODS Information on demographics, symptoms, functioning, and treatments recommended and tried were obtained on patients with JPFS as part of a multi-site patient registry (the Childhood Arthritis and Rheumatology Research Alliance Legacy Registry). Data were summarized using descriptive statistics. In a subset of patients completing registry follow-up visits, changes in symptoms, pain, and functioning were evaluated using growth modeling. RESULTS Of the 201 patients with JPFS enrolled in the registry, most were Caucasian/White (85%), non-Hispanic (83%), and female (84%). Ages ranged from 9 to 20 years (M = 15.4 + 2.2). The most common symptoms reported were widespread musculoskeletal pain (91%), fatigue (84%), disordered sleep (82%), and headaches (68%). Pain intensity was rated as moderate to severe (M = 6.3 + 2.4/10). Scores on measures of functioning indicated mild to moderate impairment, with males observed to report significantly greater impairments. For the 37% of the initial cohort having follow-up data available, indicators of function and well-being were found to either worsen over time or remain relatively unchanged. CONCLUSIONS The symptoms of JPFS remained persistent and disabling for many patients treated by pediatric rheumatologists. Further study appears warranted to elucidate gender differences in the impact of JPFS symptoms. Work also is needed to identify accessible and effective outpatient treatment options for JPFS that can be routinely recommended or implemented by pediatric rheumatology providers.

Human Meibum Age, Lipid-Lipid Interactions and Lipid Saturation in Meibum from Infants. Int J Mol Sci 2017; 18:ijms18091862. [PMID: 28846660 PMCID: PMC5618511 DOI: 10.3390/ijms18091862] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2017] [Revised: 07/25/2017] [Accepted: 08/17/2017] [Indexed: 01/21/2023] Open
Abstract
Tear stability decreases with increasing age and the same signs of instability are exacerbated with dry eye. Meibum lipid compositional changes with age provide insights into the biomolecules responsible for tear film instability. Meibum was collected from 69 normal donors ranging in age from 0.6 to 68 years of age. Infrared spectroscopy was used to measure meibum lipid phase transition parameters. Nuclear magnetic resonance spectroscopy was used to measure lipid saturation. Increasing human meibum lipid hydrocarbon chain unsaturation with age was related to a decrease in hydrocarbon chain order, cooperativity, and in the phase transition temperature. The change in these parameters was most dramatic between 1 and 20 years of age. Meibum was catalytically saturated to determine the effect of saturation on meibum lipid phase transition parameters. Hydrocarbon chain saturation was directly related to lipid order, phase transition temperature, cooperativity, changes in enthalpy and entropy, and could account for the changes in the lipid phase transition parameters observed with age. Unsaturation could contribute to decreased tear film stability with age.

Safety and efficacy of pregabalin in adolescents with fibromyalgia: a randomized, double-blind, placebo-controlled trial and a 6-month open-label extension study. Pediatr Rheumatol Online J 2016; 14:46. [PMID: 27475753 PMCID: PMC4967327 DOI: 10.1186/s12969-016-0106-4] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2016] [Accepted: 07/22/2016] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Fibromyalgia (FM) is a common pain condition characterized by widespread musculoskeletal pain and tenderness. Pregabalin is an approved treatment for adults in the United States, but there are no approved treatments for adolescents with FM. METHODS This was a 15-week, randomized, double-blind, placebo-controlled study and 6-month open-label safety trial of flexible-dose pregabalin (75-450 mg/day) for the treatment of adolescents (12-17 years) with FM. Primary outcome was change in mean pain score at endpoint (scored from 0-10, with 24-h recall). Secondary outcomes included global assessments and measures of pain, sleep, and FM impact. RESULTS A total of 107 subjects were randomized to treatment (54 pregabalin, 53 placebo) and 80 completed the study (44 pregabalin, 36 placebo). Improvement in mean pain score at endpoint with pregabalin versus placebo was not statistically significant, treatment difference (95 % CI), -0.66 (-1.51, 0.18), P = 0.121. There were significant improvements with pregabalin versus placebo in secondary outcomes of change in pain score by week (P < 0.05 for 10 of 15 weeks); change in pain score at week 15 (1-week recall), treatment difference (95 % CI), -0.87 (-1.68, -0.05), P = 0.037; and patient global impression of change, 53.1 % versus 29.5 % very much or much improved (P = 0.013). Trends toward improvement with pregabalin in other secondary outcomes measuring pain, sleep, and FM impact were not significant. Safety was consistent with the known profile of pregabalin in adults with FM. CONCLUSION Pregabalin did not significantly improve the mean pain score in adolescents with FM. There were significant improvements in secondary outcomes measuring pain and impression of change. TRIAL REGISTRATIONS NCT01020474 ; NCT01020526 .

Utility of the PedsQL rheumatology module as an outcome measure in juvenile fibromyalgia. Arthritis Care Res (Hoboken) 2014; 65:1820-7. [PMID: 23686969 DOI: 10.1002/acr.22045] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2012] [Revised: 02/27/2013] [Accepted: 05/06/2013] [Indexed: 11/05/2022]
Abstract
OBJECTIVE The PedsQL rheumatology module is currently the only available measure of disease-specific quality of life for children and adolescents with juvenile fibromyalgia (FM), but limited information has been published about the psychometric properties of the instrument, specifically in juvenile FM. The objective of this study was to assess there liability, validity, and sensitivity to change of the 5 scales (pain and hurt, daily activities, treatment, worry, and communication) of the patient and parent proxy versions of the PedsQL rheumatology module in the context of a randomized controlled trial in juvenile FM. METHODS The entire PedsQL rheumatology module was administered as a supplementary outcome measure at baseline,posttreatment, and 6-month followup assessments of 114 children and adolescents with juvenile FM enrolled in a trial testing the efficacy of cognitive–behavioral therapy. RESULTS Internal consistency reliabilities for the scales were adequate to strong (Cronbach’s α = 0.68–0.86). Parent proxy and child reports on most scales (except for daily activities and communication) showed moderate correlations (Spearman’s r = 0.33–0.45). Support for construct validity was found by comparing child and parent reports with other related measures of pain and functioning (visual analog scale pain ratings and the Functional Disability Inventory). Finally, sensitivity to change was demonstrated by significant changes in 4 of the 5 scales (excluding the daily activities scale) after treatment. CONCLUSION The PedsQL rheumatology module generally appears to have good utility for use in juvenile FM patients, but there are some caveats to the interpretation of specific scales in this population.

Identifying treatment responders and predictors of improvement after cognitive-behavioral therapy for juvenile fibromyalgia. Pain 2014; 155:1206-1212. [PMID: 24650858 DOI: 10.1016/j.pain.2014.03.005] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2013] [Revised: 02/20/2014] [Accepted: 03/06/2014] [Indexed: 11/16/2022]
Abstract
The primary objective of this study was to estimate a clinically significant and quantifiable change in functional disability to identify treatment responders in a clinical trial of cognitive-behavioral therapy (CBT) for youth with juvenile fibromyalgia (JFM). The second objective was to examine whether baseline functional disability (Functional Disability Inventory), pain intensity, depressive symptoms (Children's Depression Inventory), coping self-efficacy (Pain Coping Questionnaire), and parental pain history predicted treatment response in disability at 6-month follow-up. Participants were 100 adolescents (11-18 years of age) with JFM enrolled in a recently published clinical trial comparing CBT to a fibromyalgia education (FE) intervention. Patients were identified as achieving a clinically significant change in disability (i.e., were considered treatment responders) if they achieved both a reliable magnitude of change (estimated as a > or = 7.8-point reduction on the FDI) using the Reliable Change Index, and a reduction in FDI disability grade based on established clinical reference points. Using this rigorous standard, 40% of patients who received CBT (20 of 50) were identified as treatment responders, compared to 28% who received FE (14 of 50). For CBT, patients with greater initial disability and higher coping efficacy were significantly more likely to achieve a clinically significant improvement in functioning. Pain intensity, depressive symptoms, and parent pain history did not significantly predict treatment response. Estimating clinically significant change for outcome measures in behavioral trials sets a high bar but is a potentially valuable approach to improve the quality of clinical trials, to enhance interpretability of treatment effects, and to challenge researchers to develop more potent and tailored interventions.

Abstract
OBJECTIVE Juvenile fibromyalgia (JFM) is a chronic musculoskeletal pain condition that is associated with reduced physical function. Recent research has demonstrated that cognitive-behavioral therapy (CBT) is effective in improving daily functioning among adolescents with JFM. However, it is not known whether these improvements were accompanied by increased physical activity levels. Our objective was to analyze secondary data from a randomized clinical trial of CBT to examine whether CBT was associated with improvement in objectively measured physical activity and whether actigraphy indices corresponded with self-reported functioning among adolescents with JFM. METHODS Participants were 114 adolescents (ages 11-18 years) recruited from pediatric rheumatology clinics that met criteria for JFM and were enrolled in a clinical trial. Subjects were randomly (1:1) assigned to receive either CBT or fibromyalgia education (FE). Participants wore a hip-mounted accelerometer for 1 week as part of their baseline and posttreatment assessments. RESULTS The final sample included 68 subjects (94% female, mean age 15.2 years) for whom complete actigraphy data were obtained. Actigraphy measures were not found to correspond with self-reported improvements in functioning. While self-reported functioning improved in the CBT condition compared to FE, no significant changes were seen in either group for activity counts, sedentary, moderate, or vigorous activity. The CBT group had significantly lower peak and light activity at posttreatment. CONCLUSION Actigraphy monitoring provides a unique source of information about patient outcomes. CBT intervention was not associated with increased physical activity in adolescents with JFM, indicating that combining CBT with interventions to increase physical activity may enhance treatment effects.

Changes in pain coping, catastrophizing, and coping efficacy after cognitive-behavioral therapy in children and adolescents with juvenile fibromyalgia. THE JOURNAL OF PAIN 2013; 14:492-501. [PMID: 23541069 DOI: 10.1016/j.jpain.2012.12.019] [Citation(s) in RCA: 70] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2012] [Revised: 12/03/2012] [Accepted: 12/29/2012] [Indexed: 10/27/2022]
Abstract
UNLABELLED A recent randomized multisite clinical trial found that cognitive-behavioral therapy (CBT) was significantly more effective than fibromyalgia education (FE) in reducing functional disability in adolescents with juvenile fibromyalgia (JFM). The primary objective of this study was to examine the psychological processes of CBT effectiveness by evaluating changes in pain coping, catastrophizing, and coping efficacy and to test these changes as mediators of continued improvements in functional disability and depressive symptoms at 6-month follow-up. One hundred adolescents (11-18 years old) with JFM completed the clinical trial. Coping, catastrophizing, and coping efficacy (Pain Coping Questionnaire) and the outcomes of functional disability (Functional Disability Inventory) and depressive symptoms (Children's Depression Inventory) were measured at baseline, posttreatment, and 6-month follow-up. Participants in both conditions showed significant improvement in coping, catastrophizing, and efficacy by the end of the study, but significantly greater improvements were found immediately following treatment for those who received CBT. Treatment gains were maintained at follow-up. Baseline to posttreatment changes in coping, catastrophizing, and efficacy were not found to mediate improvements in functional disability or depressive symptoms from posttreatment to follow-up. Future directions for understanding mechanisms of CBT effectiveness in adolescents with chronic pain are discussed. PERSPECTIVE CBT led to significant improvements in pain coping, catastrophizing, and efficacy that were sustained over time in adolescents with juvenile fibromyalgia. Clinicians treating adolescents with JFM should focus on teaching a variety of adaptive coping strategies to help patients simultaneously regain functioning and improve mood.

Abstract
OBJECTIVE There is wide variation in therapeutic approaches to systemic juvenile idiopathic arthritis (JIA) among North American rheumatologists. Understanding the comparative effectiveness of the diverse therapeutic options available for treatment of systemic JIA can result in better health outcomes. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed consensus treatment plans and standardized assessment schedules for use in clinical practice to facilitate such studies. METHODS Case-based surveys were administered to CARRA members to identify prevailing treatments for new-onset systemic JIA. A 2-day consensus conference in April 2010 employed modified nominal group technique to formulate preliminary treatment plans and determine important data elements for collection. Followup surveys were employed to refine the plans and assess clinical acceptability. RESULTS The initial case-based survey identified significant variability among current treatment approaches for new-onset systemic JIA, underscoring the utility of standardized plans to evaluate comparative effectiveness. We developed 4 consensus treatment plans for the first 9 months of therapy, as well as case definitions and clinical and laboratory monitoring schedules. The 4 treatment regimens included glucocorticoids only, or therapy with methotrexate, anakinra, or tocilizumab, with or without glucocorticoids. This approach was approved by >78% of the CARRA membership. CONCLUSION Four standardized treatment plans were developed for new-onset systemic JIA. Coupled with data collection at defined intervals, use of these treatment plans will create the opportunity to evaluate comparative effectiveness in an observational setting to optimize initial management of systemic JIA.

Abstract
OBJECTIVE To determine whether adult disease severity subclassification systems for antineutrophil cytoplasmic antibody-associated vasculitis (AAV) are concordant with the decision to treat pediatric patients with cyclophosphamide (CYC). METHODS We applied the European Vasculitis Study (EUVAS) and Wegener's Granulomatosis Etanercept Trial (WGET) disease severity subclassification systems to pediatric patients with AAV in A Registry for Childhood Vasculitis (ARChiVe). Modifications were made to the EUVAS and WGET systems to enable their application to this cohort of children. Treatment was categorized into 2 groups, "cyclophosphamide" and "no cyclophosphamide." Pearson's chi-square and Kendall's rank correlation coefficient statistical analyses were used to determine the relationship between disease severity subgroup and treatment at the time of diagnosis. RESULTS In total, 125 children with AAV were studied. Severity subgroup was associated with treatment group in both the EUVAS (chi-square 45.14, p < 0.001, Kendall's tau-b 0.601, p < 0.001) and WGET (chi-square 59.33, p < 0.001, Kendall's tau-b 0.689, p < 0.001) systems; however, 7 children classified by both systems as having less severe disease received CYC, and 6 children classified as having severe disease by both systems did not receive CYC. CONCLUSION In this pediatric AAV cohort, the EUVAS and WGET adult severity subclassification systems had strong correlation with physician choice of treatment. However, a proportion of patients received treatment that was not concordant with their assigned severity subclass.

Abstract
OBJECTIVE Granulomatosis with polyangiitis (Wegener's; GPA) and other antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are rare in childhood and are sometimes difficult to discriminate. We compared use of adult-derived classification schemes for GPA against validated pediatric criteria in the ARChiVe (A Registry for Childhood Vasculitis e-entry) cohort, a Childhood Arthritis and Rheumatology Research Alliance initiative. METHODS Time-of-diagnosis data for children with physician (MD) diagnosis of AAV and unclassified vasculitis (UCV) from 33 US/Canadian centers were analyzed. The European Medicines Agency (EMA) classification algorithm and European League Against Rheumatism/Paediatric Rheumatology International Trials Organisation/Paediatric Rheumatology European Society (EULAR/PRINTO/PRES) and American College of Rheumatology (ACR) criteria for GPA were applied to all patients. Sensitivity and specificity were calculated (MD-diagnosis as reference). RESULTS MD-diagnoses for 155 children were 100 GPA, 25 microscopic polyangiitis (MPA), 6 ANCA-positive pauciimmune glomerulonephritis, 3 Churg-Strauss syndrome, and 21 UCV. Of these, 114 had GPA as defined by EMA, 98 by EULAR/PRINTO/PRES, and 87 by ACR. Fourteen patients were identified as GPA by EULAR/PRINTO/PRES but not by ACR; 3 were identified as GPA by ACR but not EULAR/PRINTO/PRES. Using the EMA algorithm, 135 (87%) children were classifiable. The sensitivity of the EMA algorithm, the EULAR/PRINTO/PRES, and ACR criteria for classifying GPA was 90%, 77%, and 69%, respectively, with specificities of 56%, 62%, and 67%. The relatively poor sensitivity of the 2 criteria related to their inability to discriminate patients with MPA. CONCLUSION EULAR/PRINTO/PRES was more sensitive than ACR criteria in classifying pediatric GPA. Neither classification system has criteria for MPA; therefore usefulness in discriminating patients in ARChiVe was limited. Even when using the most sensitive EMA algorithm, many children remained unclassified.

Abstract
OBJECTIVE Juvenile fibromyalgia syndrome (FMS) is a chronic musculoskeletal pain disorder in children and adolescents for which there are no evidence-based treatments. The objective of this multisite, single-blind, randomized clinical trial was to test whether cognitive-behavioral therapy (CBT) was superior to fibromyalgia (FM) education in reducing functional disability, pain, and symptoms of depression in juvenile FMS. METHODS Participants were 114 adolescents (ages 11-18 years) with juvenile FMS. After receiving stable medications for 8 weeks, patients were randomized to either CBT or FM education and received 8 weekly individual sessions with a therapist and 2 booster sessions. Assessments were conducted at baseline, immediately following the 8-week treatment phase, and at 6-month followup. RESULTS The majority of patients (87.7%) completed the trial per protocol. Intent-to-treat analyses showed that patients in both groups had significant reductions in functional disability, pain, and symptoms of depression at the end of the study, and CBT was significantly superior to FM education in reducing the primary outcome of functional disability (mean baseline to end-of-treatment difference between groups 5.39 [95% confidence interval 1.57, 9.22]). Reduction in symptoms of depression was clinically significant for both groups, with mean scores in the range of normal/nondepressed by the end of the study. Reduction in pain was not clinically significant for either group (<30% decrease in pain). There were no study-related adverse events. CONCLUSION In this controlled trial, CBT was found to be a safe and effective treatment for reducing functional disability and symptoms of depression in adolescents with juvenile FMS.

Abstract
UNLABELLED Juvenile primary fibromyalgia syndrome (JPFS) is a chronic pain condition associated with significant impairment in physical functioning, but no studies have used newer technologies such as actigraphy to document objective physical activity levels in JPFS. This is the first study to objectively describe physical activity in JPFS patients and examine the relationship of pain, perceived functional impairment, and depressive symptoms on physical activity. One hundred four clinically referred adolescents with JPFS (ages 11 to 18 years) wore a hip-mounted actigraph for 1 week. Data on pain intensity, functional disability, depressive symptoms, and psychiatric diagnoses were obtained using self- and parent-report measures and a standardized psychiatric interview. Results showed that younger patients were more active. Pain intensity was not significantly associated with physical activity levels overall, but the most highly active group of adolescents reported lower levels of pain and disability than the least active. Parent report of adolescents' physical functioning and depressive symptoms were significantly correlated with adolescents' physical activity levels. Actigraphy provides a unique source of information about physical functioning which is distinct from adolescents' self-report of physical functioning in JPFS. Preliminary findings suggest that further study of factors that predict perceived and actual physical functioning in JPFS is warranted. PERSPECTIVE This study presents the results of physical activity monitoring in adolescents with JPFS using actigraphy. Results indicate that actigraphy provides a unique source of objective information that can advance our understanding of physical disability in JPFS and the factors associated with physical impairment.

Abstract
OBJECTIVE To describe school absences in adolescents with Juvenile Primary Fibromyalgia Syndrome (JPFS) and examine the relationship between school absenteeism, pain, psychiatric symptoms, and maternal pain history. METHODS Adolescents with JPFS (N = 102; mean age 14.96 years) completed measures of pain and depressive symptoms, and completed a psychiatric interview. Parents provided information about the adolescents' school absences, type of schooling, and parental pain history. School attendance reports were obtained directly from schools. RESULTS Over 12% of adolescents with JPFS were homeschooled. Those enrolled in regular school missed 2.9 days per month on average, with one-third of participants missing more than 3 days per month. Pain and maternal pain history were not related to school absenteeism. However, depressive symptoms were significantly associated with school absences. CONCLUSION Many adolescents with JPFS experience difficulties with regular school attendance. Long-term risks associated with school absenteeism and the importance of addressing psychological factors are discussed.

Abstract
OBJECTIVE To examine the effects of daily supplementation with calcium (Ca) in combination with vitamin D on total body and lumbar spine bone mineral density (BMD) in patients with juvenile rheumatoid arthritis (JRA) who had not taken corticosteroids for at least 3 months prior to the beginning of the study. METHODS One hundred ninety-eight children and adolescents (141 girls and 57 boys) with JRA, ages 6 to 18 years, with a mean +/- SD age of 11.7 +/- 3.3 years and a mean +/- SD disease duration of 5.6 +/- 3.8 years at the beginning of the study, were enrolled in this randomized double-blind, placebo-controlled trial to receive either daily oral supplements of 1,000 mg of Ca and 400 IU of vitamin D (n = 103) or matched placebo tablets and 400 IU of vitamin D (n = 95) for 24 months. Total body BMD (TBBMD) was measured by dual x-ray absorptiometry at baseline and every 6 months for 24 months. RESULTS At baseline, the mean +/- SD TBBMD was 0.89 +/- 0.14 gm/cm2 among patients randomized to the Ca group and 0.87 +/- 0.14 gm/cm2 among those randomized to placebo (P = 0.445). At 24 months, the mean +/- SD TBBMD among those receiving Ca was 0.95 +/- 0.13 gm/cm2, compared with 0.92 +/- 0.14 gm/cm2 among those receiving placebo. A longitudinal random-effects mixed model analysis that controlled for differences in the subject's initial BMD, sex, Tanner stage, adherence to the study medication regimen, and body composition revealed significantly higher TBBMD among patients who received Ca compared with patients who received placebo during the study period (P = 0.03). CONCLUSION Ca supplementation resulted in a small, but statistically significant, increase in TBBMD compared with placebo in children with JRA.

Abstract
OBJECTIVE To describe the health and functional status of children with juvenile rheumatoid arthritis (JRA) diagnosed in the early 1990s. METHODS Patients were obtained from the Pediatric Rheumatology Disease Registry, a database of patients seen in pediatric rheumatology centers across the United States. Questionnaires designed to be filled out after retrospective chart review were sent to pediatric rheumatologists caring for children diagnosed with JRA between 1992 and 1997. RESULTS We studied 703 patients -- 376 with pauciarticular onset (pauci), 232 with polyarticular onset (poly), and 95 with systemic onset JRA (systemic). At 1 year after diagnosis, half of the pauci and systemic patients no longer required medication, compared to 78% of the poly patients; 98% of the patients functioned in Steinbrocker classes I and II. Six percent of pauci, 27% of poly, and 11% of systemic patients had limitations in school function. Nearly 1/3 of poly patients already had joint space narrowing on radiograph. By 5 years after diagnosis, all pauci, 88% of poly, and 70% of systemic patients were in Steinbrocker classes I and II; but 6% of pauci, 28% of poly, and 44% of systemic patients had limitations in school function. Nearly 2/3 of poly and systemic patients had joint space narrowing. CONCLUSION In these children treated prior to the era of biologic therapy, at 5 years after onset, > 25% of poly and nearly half of systemic patients had functional limitations that required modifications in their school schedule. Radiographically evident joint space damage was seen within a year of onset in poly patients, and by 5 years 2/3 of poly and systemic patients had damage.

Abstract
Multicentric reticulohistiocytosis is a rare multisystem disorder in which an infiltration of histiocytic cells causes papulonodular skin lesions and potentially a destructive polyarthritis. The active disease typically resolves spontaneously after 5-8 years, but the articular destruction can lead to permanent joint deformities. We present a case of multicentric reticulohistiocytosis in a 14-year-old girl. The number of papules on her hands decreased in number and her arthritic symptoms improved after 4 months of oral naproxen. Thirty months later her joint symptoms remained inactive and only six very small papules remained on her hands. Small flexor deformities were present in the distal interphalangeal joints of both index fingers. This case is an example of how multicentric reticulohistiocytosis can be a relatively stable and self-limited disease but still cause permanent joint deformities.

Abstract
For the clinician evaluating adolescents with chronic musculoskeletal pain and fatigue, the distinctions between JRA and FS are clear based on physical examination findings. The two conditions can coexist. For the patient with an initial diagnosis of either JRA or FS whose clinical response to therapy is not in keeping with expectations or physical examination findings or whose clinical course worsens without explanation, reevaluation to determine if FS in the JRA patient has developed or JRA in the FS patient has emerged is warranted. Until clinicians have a better understanding of the intricacies of the neurohormonal and immunologic systems and how they affect somatic symptoms, they can continue to provide patients with a treatment plan based on current knowledge that should minimize patients' discomfort and allow them to have appropriately functional lives.

Abstract
OBJECTIVE To develop, validate, and determine the measurement characteristics of a quantitative tool for assessing the severity of muscle involvement in children with idiopathic inflammatory myopathies. METHODS The Childhood Myositis Assessment Scale (CMAS) was developed from 2 existing observational functional assessment tools to assess muscle function in the areas of strength and endurance across a wide range of ability and ages. The 14 ordinal items included were chosen to assess primarily axial and proximal muscle groups and are ranked with standard performance and scoring methods. Following the development of the CMAS, a training video and written instructions were developed and reviewed by the physicians participating in this study. Subsequently, utilizing a randomized block design, 12 physicians independently scored 10 children (9 with dermatomyositis, 1 with polymyositis; ages 4-15 years) twice in one day (morning and afternoon) on the CMAS. A pediatric physical therapist performed quantitative manual muscle strength testing (MMT) twice on each child (morning and afternoon), including the neck, trunk, and proximal and distal extremity muscle groups. RESULTS The CMAS has a potential range of 0-51, with higher scores indicating greater muscle strength and endurance. The observed mean for the 10 patients was 36.4 (median 44, SD 14.1, observed range 5-51). The total score for the CMAS correlated with the physician's global assessment (by visual analog scale) of disease activity, the MMT score, serum creatine kinase level, and the Juvenile Arthritis Functional Assessment Report score. The score on the CMAS was not correlated with patient age. Interrater reliability (Kendall's coefficient of concordance) ranged from 0.77 to 1.0 for individual items (all P < 0.001), and overall, it was 0.95 (P < 0.001). Intrarater reliability for the individual physicians was measured by correlation of the CMAS scores for each patient on 2 separate evaluations and ranged from 0.97 to 0.99, with an overall correlation for all physicians of 0.98 (all P < 0.001). CONCLUSION The CMAS demonstrated an acceptable range of observed scores, excellent convergent validity, and excellent inter- and intrarater reliability. The CMAS is validated to quantitatively assess muscle function in the areas of strength and endurance in children with idiopathic inflammatory myopathies. It can be used in routine clinical care as well as therapeutic trials.

Abstract
OBJECTIVE To determine if psychological morbidity in youth with chronic fatigue is caused by the stress of coping with a chronic illness. STUDY DESIGN Case-control study comparing pediatric patients with debilitating chronic fatigue and matched subjects with juvenile rheumatoid arthritis, a chronic medical illness with similar functional sequelae. SETTING Pediatric Infectious Diseases Clinic and Juvenile Rheumatoid Arthritis Clinic of Kosair Children's Hospital. PARTICIPANTS Nineteen children and adolescents with debilitating chronic fatigue and 19 age- and sex-matched peers with juvenile rheumatoid arthritis. Outcome. Structured Interview, Kaufman Brief Intelligence Test, Child Behavior Checklist, and Youth Self-Report. RESULTS Intellectual functioning on the Kaufman Brief Intelligence Test Composite was average (103, standard score) for both groups. Pediatric patients with chronic fatigue had higher levels of internalizing psychological distress than patients suffering from juvenile rheumatoid arthritis, despite the fact that both groups had a similar pattern of decline in social and physical activities. Duration of illness did not explain the difference in psychological symptoms. CONCLUSIONS Psychological factors may play a more active role in debilitating chronic fatigue in pediatric patients than can be explained by the stress of coping with a similar chronic, non-life-threatening illness.

Abstract
The pulmonary manifestations of rheumatic diseases can vary substantially, both in severity and mechanism of injury. There is still relatively little experience with these conditions in the pediatric age group. Perhaps tissue diagnosis will help elucidate the pathophysiology involved and allow for the development of more specific treatment protocols.

Abstract
Children and adolescents seen by gynecologists may have a broad spectrum of emotional needs that can affect the gynecologic examination as well as the young person's overall well-being. The field of expressive therapy is a relatively new one. The therapist uses a variety of techniques to allow the patient to explore feelings, attitudes, or events in ways that may help the patient to develop new strategies to cope with distress. The application of expressive therapy in pediatric and adolescent gynecology appears to be ever more encompassing.

Abstract
Pulmonary symptoms as the initial or primary manifestation of SLE are rare. When pulmonary symptoms are present, they occur most commonly when other organ systems are involved. The absence of skin and renal involvement, the presence of normal serum complement, and the poor response to corticosteroids in this patient are of interest. Pulmonary disease produced by childhood SLE may represent, as in adults, a subgroup of SLE disease. Our report emphasizes the importance of recognizing diffuse interstitial infiltrates as an initial symptom of childhood SLE even in the absence of more obvious signs.

Abstract
Endometriosis is frequently a chronic process, which may begin soon after menarche. The process may be enhanced by mechanical obstruction. Theories of retrograde menstruation and metaplasia still remain in vogue. Endometriosis is a cause of both acute and chronic pelvic pain in the adolescent. We present case reports of müllerian lateral wall fusion defects with surgical correction and evidence for resorption of endometriosis. Clinicians must be aware that patients with uterine anomalies may develop extensive endometriosis, which upon creation of an unobstructed outflow tract results in complete resorption. Furthermore, the mechanism of formation of endometriosis in association with an outflow tract obstruction may be very different from that associated with infertility. We recommend consideration of endometriosis and/or a reproductive tract abnormality in the adolescent with persistent pelvic pain.

Abstract
Organic solvent inhalation leading to intoxication has become an important medical problem. Pulmonary function studies were performed on 42 young (ages 11-31) solvent inhalers and on 20 controls (ages 10-26). Ventilatory studies were normal in the majority, but residual volumes of inhalers were significantly higher (136.26% +/- 32.64% S.C.) than in controls (104% +/- 27.78% S.C.)--p less than 0.001. Lung tissue obtained at autopsy, from three known solvent inhalers was found to contain microscopic abnormalities similar to those seen in experimental panlobular emphysema and it is assumed these changes are consistent with increased residual volumes.

Abstract
A unique case of gonadal agenesis and rudimentary müllerian duct development in association with a 46,X,i(Xq) karyotype is reported. The patient presented with short stature and subtle features of Turner syndrome. Endocrine evaluation revealed elevated gonadotropins and cytogenetic findings from both peripheral blood leukocytes and skin fibroblasts were consistent with a 46,X,i(Xq) karyotype. Laparoscopy revealed both uterus and gonads to be absent. Developmental failure of the müllerian system in association with gonadal agenesis in a patient with 46,X,i(Xq) has not been previously reported. The basis for müllerian duct regression in this patient remains unclear. Recommendations for treatment are made.

Abstract
Eleven of 42 toluene inhalers were evaluated with computed tomography scans because of neurologic abnormalities. Six of the 11 were found to have cerebral cortical atrophy. In addition, two of the six had cerebellar atrophy. All six had been exposed to toluene for at least 10 years. This study suggests that atrophy of the central nervous system may occur in chronic toluene abusers.
