A67: Factors That Contribute to Classification of Children as Having Undifferentiated Juvenile Idiopathic Arthritis( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract : Background/Purpose: According to the ILAR criteria, undifferentiated juvenile idiopathic arthritis (U-JIA) includes children who fail to meet criteria for 1 of the other 6 categories or who meet criteria in more than 1 category. Classification requires category-specific application of 5 exclusion criteria: 1. Psoriasis in the patient or a 1 st degree relative; 2. Arthritis beginning after the 6 th birthday in an HLA-B27 + male; 3. HLAB27 associated disease in a 1st degree relative; 4. Rheumatoid factor positivity (RF+) on 2 occasions; and 5. The presence of systemic JIA (SoJIA). A pilot single-centre study (n=21) revealed that psoriasis in a 1st degree relative was the most common reason for classifying patients as U-JIA; disregarding this criterion would allow re-classification of most U-JIA patients and had no impact on the classification of JPsA patients (Chan et al., 2011). We aimed to determine the most frequent reasons for classifying children as U-JIA from a large multicenter prospective cohort of children with JIA (n=1104). Methods: Two investigators reviewed data on patients diagnosed with UJIA extracted from the Research in Arthritis in Canadian Children emphasizing Outcomes (ReACCh-Out) database. They identified by consensus the reasons for classifying patients as U-JIA and the JIA category they would fall in if the following two changes were made: disregarding psoriasis in a 1 st degree relative, considering patients as RF negative when only a single positive RF test was recorded. Results: 84 patients (51 female), were classified as U-JIA for the reasons shown in the1 . If the criterion of having a 1 st degree relative with psoriasis was disregarded, 25 patients would be classified as oligo JIA, 13 poly RF−, 5 poly RF+, 12 ERA and 2 SoJIA. If a single positive RF test was considered to be insufficient to meet the ILAR criterion of RF positivity, 9 patients would be re-classified as oligo JIA, 5 ERA, 1 SoJIA, 1 JPsA and 1 would remain U-JIA. Conclusion: Psoriasis in a 1 st degree relative is the most common factor contributing to the classification of a child as having U-JIA and removing it from the existing criteria should be considered. The presence of a single positive test for RF was the second most common reason resulting in a classification of U-JIA. Definitive RF testing (two tests) should be maintained to satisfy the criterion of "RF positivity"

A96: The Roller Coaster of Juvenile Idiopathic Arthritis: A Qualitative Examination of Parents' Emotional Responses to the Disease and Its Management( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract : Background/Purpose: During a recent study we conducted to identify patients, parents, and clinicians' priorities in describing the course of juvenile idiopathic arthritis (JIA), parents expressed intense emotions related to the disease and its management even a decade after their children's diagnosis. Here we describe the predominant emotional experiences reported by parents and how they relate to different phases of the disease manifestation, treatments, and interactions with peers and healthcare providers. Methods: We analyzed focus group transcripts and reciprocal interview answers involving 9 experienced English-speaking parents, 5 experienced French-speaking parents and 8 novice parents (between 2 and 6 months since diagnosis). Their children were 2 to 16 years of age and had a variety of JIA subtypes and disease severity. Qualitative analysis included review of audio recordings to enrich transcripts (based on pauses, noises, and other non-verbal cues), coding of emotional experiences by two investigators using a list of 69 emotion labels, coding verification by two other investigators, and analytical discussion and synthesis by our interdisciplinary team (to agree on what emotions were predominant at different stages of the disease, who or what were those emotions directed at, and how disease characteristics or parent background shaped them). Results: The time between onset and diagnosis was described by parents as a period of mounting anxiety, confusion and frustration with healthcare providers before a firm diagnosis was reached. The time shortly after diagnosis was described as a time of shock, disbelief, and fear during which parents often used denial as a coping mechanism; combined with feeling overwhelmed by a sea of information about the disease. Later in the disease course, at times of disease quiescence the predominant emotions were annoyance and worry about treatment side effects, and the fear of unpredictable flares. At times of increasing or ongoing symptoms the predominant emotions were admiration for the way their children coped with the disease, and frustration with peers and teachers that could not appreciate justification for the changes in the child's willingness to engage in physical activity and school work. This was also a time of frustration with increasing treatment and side effects. Throughout the disease parents felt a sense of powerlessness and that the disease was a "time-consuming roller coaster." The subtype of arthritis did not affect the range of emotions experienced, but influenced the proportion of time in quiescence or ongoing symptoms, and the intensity of treatments and side-effects. Conclusion: The emotional experiences of parents of children with JIA can be conceptualized, as a parent put it, as roller coaster ride made of intensely emotional ups and downs. This is similar to the emotional turmoil faced by parents of children with other chronic illnesses, but JIA usually does not confront them with the chronic grief produced by progressive degenerative illnesses or the threat of imminent death

Eritrodermia, estudio retrospectivo de 23 casos: desarrollo de un algoritmo de estudio by Rocio Orozco Topete( )

1 edition published in 1994 in Spanish and held by 1 WorldCat member library worldwide

Se llevo a cabo un estudio retrospectivo de 23 pacientes con eritrodermia (ED) vistos en el Instituto Nacional de la Nutricion durante un periodo de 9 anos. Las caracteristicas clinicas fueron similares a otras series publicadas en la literatura. Las causas mas frecuentes fueron: Psoriasis 22 por ciento, dermatitis atopica 17 por ciento, micosis fungoides 17 por ciento, eritrodermia idiopatica 17 por ciento, reaccion medicamentosa 13 por ciento y otros 21.6 por ciento. En un promedio de 22 meses despues del diagnostico el 78 por ciento de los casos se encontraban en remision, siendo la prednisona la droga mas usada en el tratamiento (21 casos). Cinco enfermos murieron, tres de ellos por infecciones asociadas al tratamiento. Los datos de mayor utilidad para el diagnostico diferencial fueron la historia de dermatosis previa, o exposicion a medicamentos, la presencia de adenomegalia, eosinofilia, la biopsia de piel y en algunos casos la de ganglio. Se propone un algoritmo de estudio de ED a partir de la historia clinica y de los resultados de laboratorio e histopatologia(AU)
Comparing Presenting Clinical Features in 48 Children With Microscopic Polyangiitis to 183 Children Who Have Granulomatosis With Polyangiitis (Wegener's): An ARChiVe Cohort Study( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract : Objective: To uniquely classify children with microscopic polyangiitis (MPA), to describe their demographic characteristics, presenting clinical features, and initial treatments in comparison to patients with granulomatosis with polyangiitis (Wegener's) (GPA). Methods: The European Medicines Agency (EMA) classification algorithm was applied by computation to categorical data from patients recruited to the ARChiVe (A Registry for Childhood Vasculitis: e-entry) cohort, with the data censored to November 2015. The EMA algorithm was used to uniquely distinguish children with MPA from children with GPA, whose diagnoses had been classified according to both adult- and pediatric-specific criteria. Descriptive statistics were used for comparisons. Results: In total, 231 of 440 patients (64% female) fulfilled the classification criteria for either MPA (n = 48) or GPA (n = 183). The median time to diagnosis was 1.6 months in the MPA group and 2.1 months in the GPA group (ranging to 39 and 73 months, respectively). Patients with MPA were significantly younger than those with GPA (median age 11 years versus 14 years). Constitutional features were equally common between the groups. In patients with MPA compared to those with GPA, pulmonary manifestations were less frequent (44% versus 74%) and less severe (primarily, hemorrhage, requirement for supplemental oxygen, and pulmonary failure). Renal pathologic features were frequently found in both groups (75% of patients with MPA versus 83% of patients with GPA) but tended toward greater severity in those with MPA (primarily, nephrotic-range proteinuria, requirement for dialysis, and end-stage renal disease). Airway/eye involvement was absent among patients with MPA, because these GPA-defining features preclude a diagnosis of MPA within the EMA algorithm. Similar proportions of patients with MPA and those with GPA received combination therapy with corticosteroids plus cyclophosphamide (69% and 78%, respectively) or both drugs in combination with plasmapheresis (19% and 22%, respectively). Other treatments administered, ranging in decreasing frequency from 13% to 3%, were rituximab, methotrexate, azathioprine, and mycophenolate mofetil. Conclusion: Younger age at disease onset and, perhaps, both gastrointestinal manifestations and more severe kidney disease seem to characterize the clinical profile in children with MPA compared to those with GPA. Delay in diagnosis suggests that recognition of these systemic vasculitides is suboptimal. Compared with adults, initial treatment regimens in children were comparable, but the complete reversal of female-to-male disease prevalence ratios is a provocative finding

A13: The Research in Arthritis in Canadian Children Emphasizing Outcomes (ReACCh Out) Cohort: Prospective Determination of the Incidence of New Onset Uveitis in Juvenile Idiopathic Arthritis( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract : Background/Purpose: Previous studies of uveitis in Juvenile Idiopathic Arthritis (JIA) patients have reported prevalence and not incidence. The ReACCh Out cohort, a large inception cohort of newly diagnosed JIA patients provided the opportunity to prospectively ascertain the true incidence of new onset uveitis. The objectives of this study were to determine the overall incidence rate and its trajectory over time. Methods: ReACCh Out recruited newly diagnosed JIA patients between January 2005 and December 2010, from 16 Canadian centres across the country. Prospective data was collected every 6 months for the first 2 years, then yearly. Data was collected on numerous clinical and laboratory measures including the diagnosis of uveitis and its complications, determined by an ophthalmologist. A Poisson model was used to estimate the overall incidence rate. A Kaplan-Meier plot was used to evaluate the time from diagnosis of JIA to the time of diagnosis of new onset uveitis. Results: 1104 patients with newly diagnosed (d" months) JIA with e" follow-up visit were reviewed. Patients were predominantly female (63%), age at diagnosis was 9.3 (3.9, 13.0) years. Time from diagnosis to enrollment was 0.3 (0, 1.6) months. Follow-up to last visit or study end was 34.2 (21.5, 48) months. 23 patients whose uveitis status was not available, were excluded. 77 patients with new onset uveitis were identified during the study period. The overall incidence rate of new cases of uveitis following the diagnosis of JIA was 2.9% per year (95% confidence interval 2.3-3.6). Following the trajectory of new cases of uveitis over time, the incidence of new cases showed a slow decline over time (Figure1). Importantly, new cases of uveitis occurred as far out from diagnosis as the end of the study period. Kaplan-Meier plots were also used to evaluate age at diagnosis of new onset uveitis and gender. Results support previously identified risk factors for uveitis including younger age (<5 years) and female gender. The frequency of uveitis occurred in the JIA patients in the following distribution according to subtype: oligoarthritis (43, 56%), polyarthritis RF negative (18, 23%), polyarthritis RF positive (1, 1%), psoriatic (4, 5%), ERA (1, 1%), systemic (1, 1%) and undifferentiated (9, 12%). Conclusion: In a large inception cohort of newly diagnosed JIA patients followed prospectively, the overall incidence rate of new cases of uveitis was 2.9% per year. The slow decrease in incidence over time and the development of new cases of uveitis years later, highlight the importance of ongoing and long term surveillance
Complicaciones de la venoclisis en ninos by Jaime Guzman( )

1 edition published in 1986 in Spanish and held by 1 WorldCat member library worldwide

Durante un periodo de dos meses se realizo un estudio prospectivo, longitudinal y observacional, de 1,032 venoclisis instaladas en 342 niños internados en cuatro servicios generales de un hospital pediatrico. En 903 venoclisis se utilizo aguja de mariposa de acero inoxidable y en 129, cateteres de teflon. Las principales complicaciones observadas fueron flebitis (55.2%), cuerda residual (28.5%), infiltracion (28.1%) y obstruccion (19.5%). Doce casos (1.2%) presentaron necrosis dermica y dos (0.2%) flebitis supurada. Se observo incremento del riesgo de flebitis a mayor tiempo de permanencia de la venoclisis, asi como mayor duracion de la fase aguda de la inflamacion venosa, cuando ocurrio retraso en el retiro de la canula instalada. Se evidencio asi mismo mayor riesgo de flebitis en pacientes infectados, con dermatosis, en aquellos que recibieron dicloxacilina y con venoclisis instaladas en el pie (AU)
