RESUMEN

OBJECTIVE: To develop evidence-based recommendations for the non-pharmacological management of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). METHODS: A task force comprising 7 rheumatologists, 15 other healthcare professionals and 3 patients was established. Following a systematic literature review performed to inform the recommendations, statements were formulated, discussed during online meetings and graded based on risk of bias assessment, level of evidence (LoE) and strength of recommendation (SoR; scale A-D, A comprising consistent LoE 1 studies, D comprising LoE 4 or inconsistent studies), following the European Alliance of Associations for Rheumatology standard operating procedure. Level of agreement (LoA; scale 0-10, 0 denoting complete disagreement, 10 denoting complete agreement) was determined for each statement through online voting. RESULTS: Four overarching principles and 12 recommendations were developed. These concerned common and disease-specific aspects of non-pharmacological management. SoR ranged from A to D. The mean LoA with the overarching principles and recommendations ranged from 8.4 to 9.7. Briefly, non-pharmacological management of SLE and SSc should be tailored, person-centred and participatory. It is not intended to preclude but rather complement pharmacotherapy. Patients should be offered education and support for physical exercise, smoking cessation and avoidance of cold exposure. Photoprotection and psychosocial interventions are important for SLE patients, while mouth and hand exercises are important in SSc. CONCLUSIONS: The recommendations will guide healthcare professionals and patients towards a holistic and personalised management of SLE and SSc. Research and educational agendas were developed to address needs towards a higher evidence level, enhancement of clinician-patient communication and improved outcomes.

RESUMEN

Surgical control has prognostic value in neuroblastoma (NB). Advanced NB is common at diagnosis in South Africa. We investigated the pre-surgery factors that influenced decisions to perform surgical resections. We included 204 patients with high-risk NB from a national retrospective study, who completed induction chemotherapy between 2000 and 2016.The median age was 32.4 months (IQR 15.1 - 53.5 months). Primary tumor resection was achieved in 76.9% of patients between 0-18 months of age, 51.8% between 18-60 months and 51.7% older than 60 months (p < 0.001). Only 43.2% of patients with distant metastatic disease had surgery done (p < 0.001). LDH was >750 U/L in 46.8% and ferritin >120 g/dL in 53.1% of those who had surgery (p = 0.005). The majority (80.4%), who had achieved post-induction metastatic complete remission (mCR), were operated, while 28.7% without mCR had surgery (p < 0.001). The long-term overall survival in patients with mCR and primary tumor resection was 36.5% compared to those with mCR without primary tumor resection (25.4%) and without mCR (≤3.0%)(p < 0.001). Age (p < 0.001), stage (p < 0.001), mCR (p < 0.001) and treatment setting (p < 0.001) were of prognostic significance. The tumor site and MYCN-amplification did not significantly predict resection rates. Post-induction mCR and stage were associated with surgical resection and five-year OS (p < 0.001) on multivariate analysis.Patients with high-risk NB who achieved mCR and had primary tumor resections are curable in limited resourced settings. Stage and post-induction mCR were significant variables that led to surgery. These variables should be included as indications in the management of metastatic NB in resource limited settings.


High-risk neuroblastoma that achieved post-induction chemotherapy metastatic remission and have undergone resection, is curable, even in limited resource settings.Achieving metastatic complete remission was the only factor that significantly predicated if surgery was done.The age at diagnosis, stage and hospitals with expertise in neuroblastoma surgery were of prognostic significance in South Africa.If a patient with high-risk neuroblastoma achieves metastatic complete remission in a resource limited setting, it should be an indication for resection of the primary tumor.

RESUMEN

STUDY DESIGN: Invited Clinical Commentary BACKGROUND: Arthritis is one of the most frequently reported causes of disability in the United States and the prevalence is expected to increase in the coming decades. While many rheumatic diseases involve hand impairments, most are systemic and involve more than the musculoskeletal system. Functional and work disability are high and people would benefit from the services of occupational and physical therapists. PURPOSE OF STUDY: This paper reviews concepts of self-management, and symptoms that contribute to limitations and restrictions to participation in daily life in people with rheumatic diseases and suggests roles for hand therapists beyond the immediate hand impairments. METHODS: The impact of selected rheumatic diseases on functional and work disability are reviewed along with strategies for symptom management and self-management. Upper extremity impairments of selected rheumatic diseases are also discussed. RESULTS: The role for hand therapists in evaluating and addressing the complex needs of persons with rheumatic diseases, including less common diseases, is discussed. Outcome measures for fatigue, muscle involvement, ergonomics and computer use, and work disability are introduced. Finally, strategies for self-management and prevention of work and functional disability, along with symptom management for fatigue and pain are presented. CONCLUSION: Hand therapists can play a vital role in chronic rheumatic disease management to improve self-management and increase participation in meaningful activities. Patients, primary care and rheumatology providers need to be educated about the scope of services occupational and physical therapists provide beyond the hand impairments.

RESUMEN

PURPOSE: The aim of the World Health Organization-International Paediatric Oncology Society is to improve childhood cancer survival in low- and middle-income countries to 60% by 2030. This can be achieved using standardised evidence-based national treatment protocols for common childhood cancers. The aim of the study was to describe the development and implementation of the SACCSG NB-2017 neuroblastoma (NB) treatment protocol as part of the treatment harmonisation process of the South African Children's Cancer Study Group. METHODS: The Consolidated Framework for Implementation Research was used to identify factors that could influence the implementation of the national NB protocol as a health care intervention. The evaluation was done according to five interactive domains for implementation: intervention characteristics, inner setting, outer setting, individual or team characteristics and the implementation process. RESULTS: The protocol was developed over 26 months by 26 physicians involved in childhood cancer management. The process included an organisational phase, a resource identification phase, a development phase and a research ethics approval phase. Challenges included nationalised inertia, variable research ethical approval procedures with delays and uncoordinated clinical trial implementation. CONCLUSION: The implementation of the national NB protocol demonstrated the complexity of the implementation of a national childhood cancer treatment protocol. However, standardised paediatric cancer treatment protocols based on local expertise and resources in limited settings are feasible.

RESUMEN

PURPOSE: Low- and middle-income countries (LMICs) reported a higher median age at diagnosis of neuroblastoma (NB) compared to high-income countries. The aim was to determine if the optimal age at diagnosis, which maximizes the difference in overall survival between younger versus older patients in the South African population was similar to the internationally validated 18 months age cut-point. METHODS: Four hundred sixty NB patients diagnosed between 2000 and 2016 were included. Receiver operating characteristic (ROC) curves were used to predict potential age cut-point values for overall survival in all risk group classifications. Risk ratios, sensitivity, specificity, and positive and negative predictive values at the specific cut-points were estimated with 95% confidence intervals, and time to mortality by age at the specific cut-points was shown with Kaplan-Meier curves and compared using log-rank tests. RESULTS: The median age at diagnosis for the total cohort was 31.9 months (range 0.2-204.7). For high-risk (HR), intermediate-risk, low-risk, and very low-risk patients, the median age at diagnosis was, respectively, 36 months (range 0.4-204.7), 16.8 months (range 0.7-145.1), 14.2 months (range 2.0-143.5), and 8.7 months (range 0.2-75.6). The ROC curves for the total NB cohort (area under the curve [AUC] 0.696; P < .001) and HR (AUC 0.682; P < .001) were analyzed further. The optimal cut-point value for the total cohort was at 19.1 months (sensitivity 59%; specificity 78%). The HR cohort had potential cut-point values identified at 18.4 months age at diagnosis (sensitivity 45%; specificity 87%) and 31.1 months (sensitivity 67%; specificity 62%). The 19.1 months cut-point value in the total cohort and the 18.4 months cut-point value in HR were as useful in predicting overall survival as 18 months age at diagnosis. CONCLUSION: The 18 months cut-point value appears to be the appropriate age for prognostic determination, despite the higher median age at diagnosis in South Africa.

RESUMEN

OBJECTIVES: In a longitudinal case-control observational study, we evaluated the benefits of a self-management programme for hands developed for patients with SSc. METHODS: Patients with SSc included in the intervention group (IG) received a concise self-management programme with emphasis on hand exercises and were evaluated during 24 weeks regarding hand pain, hand function, range of motion, grip and tip and key pinch strength. Results were compared with a control group (CG) with no intervention using an analysis of variance for repeated measures with variables transformed into ranks (P ≤ 0.05). Effect sizes were calculated using Cohen's test. RESULTS: Of 90 patients who were evaluated, seven were excluded at enrolment and 26 were excluded during the follow-up. Data from 57 subjects (IG 40, CG 17) were used for analysis. Groups were similar at baseline, except for the Scleroderma HAQ and tip and key pinch strength. Outcome improvements were noted only in the IG (P ≤ 0.05, large effect size). In the CG, variables did not change or had even worsened (hand grip strength and finger motion). CONCLUSIONS: This self-management programme based on hand exercises for SSc resulted in pain reduction and hand function, strength and range of motion improvement. It can be a simple and useful intervention, especially when a regular rehabilitation programme is not available.

RESUMEN

STUDY DESIGN: This study used a quasi-experimental design where patients were evaluated before and after participation in the self-management program. INTRODUCTION: Hands are commonly affected in systemic sclerosis (SSc). Strategies to maintain or improve hand function are indicated upon diagnosis and throughout the course of the disease. PURPOSE OF THE STUDY: The purpose of this study was to develop and evaluate a home-based program for hands in patients with SSc. METHODS: A home-based self-management program that consisted of concise instructions about SSc and hand exercises was developed and evaluated in a group of patients with SSc during 8 weeks. Primary outcome measures were hand pain (Visual Analogue Scale) and hand function (Cochin Hand Function Scale). Secondary outcome measures were disability (Scleroderma Health Assessment Questionnaire), finger motion (delta finger-to-palm), grip strength, tip and key pinch strength, Raynaud phenomenon and digital ulcers impact, quality of life (Short Form Health Survey). For comparisons between different times analysis of variance for repeated measures was used. To calculate the effect size (ES), the Cohen's test was performed. To evaluate skin moisturizing and warming habits before and after intervention, the McNemar test was used. Statistical significance was set at P ≤ .05. RESULTS: Twenty-two SSc patients (19 women: 3 men; 16 limited scleroderma: 6 diffuse scleroderma) completed the program. Significant improvements were noted for hand pain (3.97 vs 2.21, ES: 0.69), Cochin Hand Function Scale (19.24 vs 12.48, ES: 0.48), Scleroderma Health Assessment Questionnaire (0.95 vs 0.48, ES: 1.01), delta finger-to-palm (92.86 vs 106.33, ES: 0.40), grip strength (14.43 vs 19, ES: 0.58), tip pinch strength (2.49 vs 4.18, ES: 1.15), key pinch strength (4.01 vs 5.22, ES: 0.76), Raynaud phenomenon impact (0.94 vs 0.47, ES: 0.75), Short Form Health Survey-role physical (47.38 vs 60.14, ES: 0.61), physical functioning (34.62 vs 61.9, ES: 0.18), social functioning (60.71 vs 75.6, ES: 0.64), bodily pain (50.55 vs 63.38, ES: 0.58), vitality (45.95 vs 62, ES: 2.22), mental health (56.62 vs 72.38, ES: 0.84) moisturizing, and cold avoidance habits. Patients considered the program easy to follow with no adverse effects related to exercises. DISCUSSION: We developed a home based hand care program to be offered to SSc patients. Improvements in hand function, strength, disability, motion, and overall quality of life were independent of age, income, education level, disease duration, and skin score. Our findings support those of other studies that reported the benefits of hand exercises in SSc. Some study limitations include the lack of a control group, the small number of subjects and the short-time follow up. CONCLUSIONS: This home-based program for patients with SSc improved hand pain, function, mobility, and strength at the end of 8 weeks. Patient adherence and sustained efficacy is still to be determined.

RESUMEN

OBJECTIVE: Our objective was to assess the efficacy of occupational therapy-related interventions for adults with systemic lupus erythematosus (SLE). METHOD: We reviewed intervention studies published from 2000 to 2017. The method used for conducting the review was based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PEDro scale was used to evaluate methodological quality. Risk of bias was appraised with methods described by the Cochrane Methods Group. RESULTS: The final analysis included 20 studies (10 physical activity and 10 psychoeducational). Moderate evidence supports physical activity to improve depression, fatigue, exercise tolerance, and function without exacerbation of disease symptoms. Strong evidence supports psychoeducational interventions using cognitive-behavioral approaches to improve pain, depression, anxiety, perceived stress, quality of life, and function. Moderate evidence supports patient education and self-management interventions for pain, depression, anxiety, perceived stress, quality of life, and function. CONCLUSION: Further research on occupation-based interventions for people with SLE is needed.

RESUMEN

Evidence Connection articles provide a clinical application of systematic reviews developed in conjunction with the American Occupational Therapy Association's (AOTA's) Evidence-Based Practice Project. In this Evidence Connection article, we describe a case report of a person recently diagnosed with fibromyalgia. The occupational therapy assessment and intervention process in the home setting is described. Findings from the systematic review (Poole & Siegel, 2017) on this topic were published in the January/February 2017 issue of the American Journal of Occupational Therapy and in AOTA's Occupational Therapy Practice Guidelines for Adults With Arthritis and Other Rheumatic Conditions (Poole et al., 2017). Each article in this series summarizes the evidence from the published reviews on a given topic and presents an application of the evidence to a related clinical case. Evidence Connection articles illustrate how the research evidence from the reviews can be used to inform and guide clinical reasoning.

RESUMEN

The purpose of this study was to describe the experiences of fathers with scleroderma. Ten fathers with scleroderma were interviewed by telephone. Interviews were tape-recorded and transcribed verbatim. Two key themes emerged related to the emotional impact of the illness and the day to day realities of the illness with the unpredictability and rareness of the illness leading to ongoing feelings of isolation and fear of mortality. The negative influences of being a father with scleroderma included the inability of the fathers to participate in physical activities with their children such as outdoor sports and throwing balls. Being able to spend quality time with the child was a positive influence of the illness.

RESUMEN

OBJECTIVE: This systematic review addresses the effectiveness of occupational therapy-related interventions for adults with fibromyalgia. METHOD: We examined the literature published between January 2000 and June 2014. A total of 322 abstracts from five databases were reviewed. Forty-two Level I studies met the inclusion criteria. Studies were evaluated primarily with regard to the following outcomes: daily activities, pain, depressive symptoms, fatigue, and sleep. RESULTS: Strong evidence was found for interventions categorized for this review as cognitive-behavioral interventions; relaxation and stress management; emotional disclosure; physical activity; and multidisciplinary interventions for improving daily living, pain, depressive symptoms, and fatigue. There was limited to no evidence for self-management, and few interventions resulted in better sleep. CONCLUSION: Although the evidence supports interventions within the scope of occupational therapy practice for people with fibromyalgia, few interventions were occupation based.

RESUMEN

OBJECTIVE: We reviewed the efficacy of occupational therapy-related interventions for adults with rheumatoid arthritis. METHOD: We examined 51 Level I studies (19 physical activity, 32 psychoeducational) published 2000-2014 and identified from five databases. Interventions that focused solely on the upper or lower extremities were not included. RESULTS: Findings related to key outcomes (activities of daily living, ability, pain, fatigue, depression, self-efficacy, disease symptoms) are presented. Strong evidence supports the use of aerobic exercise, resistive exercise, and aquatic therapy. Mixed to limited evidence supports dynamic exercise, Tai Chi, and yoga. Among the psychoeducation interventions, strong evidence supports the use of patient education, self-management, cognitive-behavioral approaches, multidisciplinary approaches, and joint protection, and limited or mixed evidence supports the use of assistive technology and emotional disclosure. CONCLUSION: The evidence supports interventions within the scope of occupational therapy practice for rheumatoid arthritis, but few interventions were occupation based.

RESUMEN

BACKGROUND: Clinical manifestations of renal dysfunction in childhood cancer survivors include hypertension, proteinuria, tubulopathy (and its biochemical consequences) and renal insufficiency. This study aimed to determine the factors associated with renal dysfunction in paediatric cancer survivors at a single centre in Johannesburg. PROCEDURE: A descriptive cross-sectional study was performed on 130 cancer survivors between 2 and 18 years of age. Physical examination and screening urine dipstick were performed on all patients. Blood results of samples routinely drawn were analysed. RESULTS: After a median follow-up period of 2 years, the various manifestations of renal dysfunction included decreased estimated glomerular filtration rate (eGFR), hypomagnesaemia, hypophosphataemia, proteinuria, haematuria and hypertension. In total, 34 survivors (26.15%) had at least one manifestation of renal dysfunction after completing treatment. The most prevalent manifestation of renal dysfunction was decreased eGFR (17.7%) followed by hypomagnesaemia (6.2%) and hypophosphataemia (4.6%). Patients with pre-existing renal dysfunction were three times more likely to have renal dysfunction post-treatment (P = 0.020). Ifosfamide (P = 0.010) and nephrectomy (P = 0.003) had independent significant impact on reduction in eGFR. High cumulative ifosfamide doses were identified as a possible cause for hypophosphataemia (P = 0.021). CONCLUSION: While not clinically evident in the early follow-up period, the high rate of renal dysfunction is concerning. We suggest that patients with pre-existing renal dysfunction should be assessed by a nephrologist prior to initiation of cancer therapy, and nephro-protective measures should be employed stringently in all children with cancer. Patients with decreased eGFR should be followed up closely in a multidisciplinary late effects clinic.

RESUMEN

The objective of this study was to examine activity limitations, participation, and quality of life (QOL) in American Indians with and without diabetes. It was a cross-sectional study that included 43 participants with diabetes and 31 healthy controls. Participants received evaluations of QOL, activity and participation limitations and factors such as pain, joint motion, hand function, and depression. There were no significant differences between the two groups for past, present, or future global QOL. However, there were significant differences between the two groups for the activity and participation measures and all measures of body structure/function except for left hand strength and depression. Current health and pain, and activity limitation correlated with QOL in both groups. Joint motion and participation correlated with QOL in the group with diabetes. American Indians with diabetes had more impairments in body structure and function and limitations in activities and participation compared to American Indians without diabetes.

RESUMEN

Fanconi anemia (FA) is a rare disorder of DNA repair, associated with various somatic abnormalities but characterized by hematological disease that manifests as bone marrow aplasia and malignancy. The mainstay of treatment, in developed nations, is hematopoietic stem cell transplantation (HSCT) with subsequent surveillance for solid organ and non-hematological malignancies. In South Africa, FA in the Black population is caused by a homozygous deletion mutation in the FANCG gene in more than 80% of cases. Many affected patients are not diagnosed until late in the disease course when severe cytopenia and bone marrow aplasia are already present. Most patients are not eligible for HSCT at this late stage of the disease, even when it is available in the state health care system. In this study, the hematological presentation and disease progression in 30 Black South African patients with FA, confirmed to have the FANCG founder mutation, were evaluated and compared to those described in other FA cohorts. Our results showed that patients, homozygous for the FANCG founder mutation, present with severe cytopenia but progress to bone marrow failure at similar ages to other individuals affected with FA of heterogeneous genotype. Further, the incidence of myelodysplastic syndrome is similar to that which has been previously described in other FA cohorts. Although severe cytopenia at presentation may be predicted by a higher number of somatic anomalies, the recognition of the physical FA phenotype in Black South African patients is challenging and may not be useful in expediting referral of suspected FA patients for tertiary level investigations and care. Given the late but severe hematological presentation of FA in Black South African patients, an investigative strategy is needed for earlier recognition of affected individuals to allow for possible HSCT and management of bone marrow disease.

RESUMEN

STUDY DESIGN: Descriptive, clinical measurement. INTRODUCTION: Charcot-Marie-Tooth disease (CMT) is a genetic disorder that results in demyelination or axonal degeneration in peripheral nerves. Characteristic symptoms include decreased muscle strength and sensation, particularly in the hands and feet. PURPOSE: Examine the reliability and validity of the Manual Ability Measure (MAM-36), a 36-item self-report questionnaire specific to hand function, in persons with CMT. METHODS: Fourteen participants with CMT completed the MAM-36 at two points one week apart. Participants were also administered performance-based tests for grip and pinch strength, dexterity, and sensation. RESULTS: The test-retest intraclass correlation coefficient (ICC) for the MAM-36 was 0.96. Pearson correlation coefficients showed fair to good relationships (r = 0.41-0.64) between the MAM-36 scores and most of the performance tests. CONCLUSION: The MAM-36 is a reliable and valid assessment tool for measuring hand function during everyday tasks in persons with CMT. LEVEL OF EVIDENCE: IIb.

RESUMEN

PURPOSE: Fanconi anemia is a genotypically and phenotypically heterogeneous condition, characterized microscopically by chromosomal instability and breakage. Affected individuals manifest growth restriction and congenital physical abnormalities; most progress to hematological disease including bone marrow aplasia. Black South African Fanconi anemia patients share a common causative founder mutation in the Fanconi G gene in 80% of cases (637_643delTACCGCC). The aim of this study was to investigate the genotype-physical phenotype correlation in a cohort of individuals homozygous for this mutation. METHODS: Thirty-five black patients were recruited from tertiary level hematology/oncology clinics in South Africa. Participants were subjected to a comprehensive clinical examination, documenting growth, congenital anomalies, and phenotypic variability. RESULTS: Descriptive statistical analysis showed significant growth abnormalities in many patients and a high frequency (97%) of skin pigmentary anomalies. Subtle anomalies of the eyes, ears, and hands occurred frequently (≥70%). Apart from malformations of the kidney (in 37%) and gastrointestinal tract (in 8.5%), congenital anomalies of other systems including the cardiovascular and central nervous systems, genitalia, and vertebrae were infrequent (<5%). CONCLUSION: The diagnosis of Fanconi anemia in black South African patients before the onset of hematological symptoms remains a clinical challenge, with the physical phenotype unlikely to be recognized by those without dysmorphology expertise.

RESUMEN

OBJECTIVES: In 2008 the South African Children's Cancer Study Group decided to review the epidemiology, management, and chemotherapy response of HIV-positive children with malignancy. METHODS: This is a retrospective analysis of data collected from the records of HIV-positive children diagnosed with malignancy at 7 university-based pediatric oncology units serving 8 of the 9 provinces in South Africa. RESULTS: Two hundred eighty-eight HIV-positive children were diagnosed with 289 malignancies between 1995 and 2009. Age at diagnosis ranged from 17 days to 18.64 years; median 5.79 years. Of the 220 HIV-associated malignancies, there were 97 Kaposi sarcomas, 61 Burkitt lymphomas, 47 other B-cell lymphomas including 2 primary central nervous system lymphomas, 12 Hodgkin lymphomas, and 3 leiomyosarcomas. Sixty-nine patients presented with non-AIDS-defining malignancies. More than 80% presented with advanced disease. Most patients (76.7%) were naive to antiretroviral therapy; 22.2% did not have access because it only became available in public hospitals in 2004. One hundred ninety-seven children were treated with curative intent; 91 received palliative care due to advanced malignancy and/or advanced HIV disease. Nearly one third had coexisting pathology, mostly tuberculosis. Overall survival for the whole group was 33.7%, but was 57.8% for those treated with antiretroviral therapy and chemotherapy. CONCLUSIONS: The study shows more Kaposi sarcoma and fewer primary central nervous system lymphomas among HIV-positive children than that is reported in the developed world, but confirms a higher incidence of non-Burkitt B-cell lymphoma than in HIV-negative children. The high number of non-AIDS-defining malignancies underscores the prevalence of HIV-AIDS in South Africa. The overall survival should improve with universal access to antiretrovirals and earlier diagnosis.

RESUMEN

This study compared parenting ability in mothers with systemic sclerosis (SSc) and systemic lupus erythematosus (SLE), two chronic, autoimmune, connective tissue diseases that primarily affect women. Seventy-four mothers with SSc and 68 mothers with SLE completed self-report questionnaires on demographic characteristics, pain, fatigue, occupational performance, and parenting. Results showed that mothers with SSc were slightly older, were more educated, and had decreased occupational performance. Mothers with SLE had more pain and fatigue. There were no significant differences between mothers with SSc and SLE who had children 5 years of age and younger. However, there were significant differences between the mothers with SSc and SLE who had children aged 6 to 18 years on four items on the Parenting Disability Index: playing games with child, getting up with child during the night, keeping child out of unsafe situations, and helping child solve personal/social problems. These differences may be due to differences in the levels of pain, fatigue, and occupational performance, possibly stemming from differences in disease manifestations.
