Is a combined programme of manual therapy and exercise more effective than usual care in patients with non-specific chronic neck pain? A randomized controlled trial.

OBJECTIVE: The aim of this study was to compare the effectiveness of a combined intervention of manual therapy and exercise (MET) versus usual care (UC), on disability, pain intensity and global perceived recovery, in patients with non-specific chronic neck pain (CNP). DESIGN: Randomized controlled trial. SETTING: Outpatient care units. SUBJECTS: Sixty-four non-specific CNP patients were randomly allocated to MET (n = 32) or UC (n = 32) groups. INTERVENTIONS: Participants in the MET group received 12 sessions of mobilization and exercise, whereas the UC group received 15 sessions of usual care in physiotherapy. MAIN MEASURES: The primary outcome was disability (Neck Disability Index). The secondary outcomes were pain intensity (Numeric Pain Rating Scale) and global perceived recovery (Patient Global Impression Change). Patients were assessed at baseline, three weeks, six weeks (end of treatment) and at a three-month follow-up. RESULTS: Fifty-eight participants completed the study. No significant between-group difference was observed on disability and pain intensity at baseline. A significant between-group difference was observed on disability at three-week, six-week and three-month follow-up (median (P25-P75): 6 (3.25-9.81) vs. 15.5 (11.28-20.75); P < 0.001), favouring the MET group. Regarding pain intensity, a significant between-group difference was observed at six-week and three-month follow-up (median (P25-P75): 2 (1-2.51) vs. 5 (3.33-6); P < 0.001), with superiority of effect in MET group. Concerning the global perceived recovery, a significant between-group difference was observed only at the three-month follow-up (P = 0.001), favouring the MET group. CONCLUSION: This study's findings suggest that a combination of manual therapy and exercise is more effective than usual care on disability, pain intensity and global perceived recovery.

Non-supervised breathing exercise regimen in women with fibromyalgia: A quasi-experimental exploratory study.

OBJECTIVES: To know the effectiveness and safety of non-supervised breathing exercise regimen by promoting patients' self-management, and to investigate if non-supervised breathing exercise regimen shows similar benefits to supervised regimen in improving pain and fibromyalgia (FM) impact on daily life. MATERIAL AND METHODS: Fifty-one women with FM were assigned to: supervised breathing exercise regimen group, non-supervised breathing exercise regimen group, and control group. Pain thresholds tolerance on tender points and FM impact on daily life were evaluated. RESULTS: After 12-weeks of breathing exercises statistical differences were not found between supervised and non-supervised regimen. However, supervised regimen showed additional improvements in pain thresholds tolerance and in pain-FIQ subscale. CONCLUSION: Our results suggest that performing a non-supervised breathing exercise program could be as safe and effective as the supervised regimen. However, it was observed that there could be a tendency of supervised exercise regimen to show additional benefits in terms of pain.

[Ozone Therapy in Knee Osteoarthritis: A Systematic Review]. / Ozonoterapia na Osteoartrose do Joelho: Revisão Sistemática.

INTRODUCTION: The aim of this study was to conduct a systematic review in order to examine the effectiveness of ozone therapy on knee osteoarthritis. The objectives were to evaluate the effect over time of ozone therapy in terms of knee pain, functional improvement and radiographic progression. MATERIAL AND METHODS: A search was carried out on PubMed, Embase, Cochrane Library, Scopus and Web of Science databases to identify randomized and controlled studies focusing on this association. The following descriptors were used in English: ozone therapy, knee osteoarthritis. A descriptive summary and quality assessment was made of all studies included for analysis. RESULTS: Six randomized and controlled studies were identified. The risk of bias assessment demonstrated that one study was considered as having a moderate risk of bias and the remainder a high risk of bias. No quantitative analysis of the data was performed, as the studies included were not sufficiently homogeneous. The participants in the studies were generally elderly patients with mild to moderate knee osteoarthritis. DISCUSSION: The variability of ozone therapy and the comparators demonstrates that there is no standardized therapy. Few studies reported adverse effects, and where they occurred, they were mild and associated with the procedure. CONCLUSION: Ozone therapy proved effective in the short-term in relation to placebo and when combined with hyaluronic acid, but it was not superior to other current treatments. More randomised and controlled studies are needed to evaluate the risks/benefits of ozone therapy, both in the short term and the medium/long term.

Introdução: O presente estudo teve por objetivo realizar uma revisão sistemática de forma a analisar a eficácia da ozonoterapia na osteoartrose do joelho. Os objetivos visaram avaliar o efeito temporal da ozonoterapia na dor no joelho, na melhoria funcional e na progressão radiográfica.Material e Métodos: Realizou-se uma pesquisa nas bases de dados PubMed, Embase, Cochrane Library, Scopus e Web of Science a fim de identificar estudos aleatorizados e controlados que tratassem dessa associação. Utilizaram-se os seguintes descritores em língua inglesa: 'ozone therapy', 'knee osteoarthritis'. Realizou-se um resumo descritivo e avaliação de qualidade de todos os estudos incluídos para análise.Resultados: Identificaram-se seis estudos aleatorizados e controlados relacionados com o objetivo deste trabalho. A avaliação do risco de viés mostrou que um estudo foi considerado como risco moderado de viés e os restantes como risco alto de viés. Não se realizou a análise quantitativa dos dados pois os estudos incluídos não foram suficientemente homogéneos. Os participantes dos estudos eram em geral doentes idosos com osteoartrose do joelho leve a moderada.Discussão: A variabilidade nas intervenções de ozonoterapia e comparadores, demonstra que não existe uma terapêutica estandardizada. Foram poucos os estudos que relataram os efeitos adversos, e quando aconteceu, estes eram ligeiros e associados ao procedimento.Conclusão: A ozonoterapia mostrou eficácia a curto prazo, em relação ao placebo e quando combinada com ácido hialurónico, sem ser promissora em relação aos restantes tratamentos vigentes. É importante que novos estudos aleatorizados e controlados avaliem os benefícios/riscos da ozonoterapia tanto a curto como a médio/longo prazo.

Breathing Exercises Must Be a Real and Effective Intervention to Consider in Women with Fibromyalgia: A Pilot Randomized Controlled Trial.

BACKGROUND/OBJECTIVE: Respiratory problems can aggravate pain located in the coincident areas with tender points in the upper half of the body in patients with fibromyalgia (FM) and easily become fatigued, thus can lead to a decrease in the functionality of daily activities. The purpose of this study was to examine the effects of a breathing exercises program on pain thresholds tolerance on tender points and FM impact on daily life. METHODS/DESIGN: Thirty-five women with FM (age 34-67 years) were randomly assigned to an exercise group (n = 18), performing breathing exercises (30 min/session, 7 times/week; for 12 weeks), or to a control group (n = 17). Pain thresholds tolerance on tender points were measured by the physician using digital pressure algometer and FM impact on daily life was evaluated with the Portuguese version of the Fibromyalgia Impact Questionnaire (FIQ). RESULTS: After 12 weeks of breathing exercises significant improvements were observed in the mean values of the treatment effects on pain thresholds tolerance on tender points and in the functional capacity to perform daily life, pain, and fatigue in favor of the exercise group. Gains in second rib, occiput, and supraspinatus pairs of the tender points predict improvements in the functional capacity, pain, and fatigue. CONCLUSION: Our study demonstrated that breathing exercises produced relevant benefits on pain thresholds tolerance on tender points located in the upper half of the body, some of which predicted improvements in the impact of FM in the functional capacity to perform daily life, pain, and fatigue. These results provide further support of an idea that breathing exercises are a real and effective intervention to consider in women with FM.

A consensus statement on the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) algorithm for the management of knee osteoarthritis-From evidence-based medicine to the real-life setting.

The European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) published a treatment algorithm for the management of knee osteoarthritis (OA) in 2014, which provides practical guidance for the prioritization of interventions. Further analysis of real-world data for OA provides additional evidence in support of pharmacological interventions, in terms of management of OA pain and function, avoidance of adverse events, disease-modifying effects and long-term outcomes, e.g., delay of total joint replacement surgery, and pharmacoeconomic factors such as reduction in healthcare resource utilization. This article provides an updated assessment of the literature for selected interventions in OA, focusing on real-life data, with the aim of providing easy-to-follow advice on how to establish a treatment flow in patients with knee OA in primary care clinical practice, in support of the clinicians' individualized assessment of the patient. In step 1, background maintenance therapy with symptomatic slow-acting drugs for osteoarthritis (SYSADOAs) is recommended, for which high-quality evidence is provided only for the prescription formulations of patented crystalline glucosamine sulfate and chondroitin sulfate. Paracetamol may be added for rescue analgesia only, due to limited efficacy and increasing safety signals. Topical non-steroidal anti-inflammatory drugs (NSAIDs) may provide additional symptomatic treatment with the same degree of efficacy as oral NSAIDs without the systemic safety concerns. Oral NSAIDs maintain a central role in step 2 advanced management of persistent symptoms. However, oral NSAIDs are highly heterogeneous in terms of gastrointestinal and cardiovascular safety profile, and patient stratification with careful treatment selection is advocated to maximize the risk:benefit ratio. Intra-articular hyaluronic acid as a next step provides sustained clinical benefit with effects lasting up to 6 months after a short-course of weekly injections. As a last step before surgery, the slow titration of sustained-release tramadol, a weak opioid, affords sustained analgesia with improved tolerability.

Denosumab: recent update in postmenopausal osteoporosis.

Postmenopausal osteoporosis is a major concern to public health. Fractures are the major clinical consequence of osteoporosis and are associated with substantial morbidity, mortality and health care costs. Bone strength determinants such as bone mineral density and bone quality parameters are determined by life-long remodeling of skeletal tissue. Receptor activator of nuclear factor-kB ligand (RANKL) is a cytokine essential for osteoclast differentiation, activation and survival. Denosumab (Prolia®) is a fully human monoclonal antibody for RANKL, which selectively inhibits osteoclastogenesis, being recently approved for the treatment of postmenopausal osteoporosis in women at a high or increased risk of fracture by the FDA in the United States and by the European Medicines Agency in Europe since June 2010. FREEDOM, DECIDE and STAND are the phase 3 trials comparing denosumab with placebo and alendronate in postmenopausal osteoporosis. The authors aim to update denosumab role in postmenopausal osteoporosis with a physiopathological review.

Portuguese guidelines for the use of biological agents in rheumatoid arthritis - March 2010 update.

The authors present the revised version of the Portuguese Society of Rheumatology (SPR) guidelines for the treatment of rheumatoid arthritis (RA) with biological therapies. In these guidelines the criteria for introduction and maintenance of biological agents are discussed as well as the contraindications and procedures in the case of non-responders. Biological treatment should be considered in RA patients with a disease activity score 28 (DAS 28) superior to 3.2 despite treatment with 20mg/week of methotrexate (MTX) for at least 3 months or, if such treatment is not possible, after 6 months of other conventional disease modifying drug or combination therapy. A DAS 28 score between 2.6 and 3.2 with a significant functional or radiological deterioration under treatment with conventional regimens could also constitute an indication for biological treatment. The treatment goal should be remission or, if that is not achievable, at least a low disease activity, characterized by a DAS28 lower than 3.2, without significative functional or radiological worsening. The response criteria, at the end of the first 3 months of treatment, are a decrease of 0.6 in the DAS28 score. After 6 months of treatment response criteria is defined as a decrease of more than 1.2 in the DAS28 score. Non-responders, in accordance to the Rheumatologist's clinical opinion, should try a switch to another biological agent (tumour necrosis factor antagonist, abatacept, rituximab or tocilizumab).

[Normative data for quantitative ultrasound measurement of the calcaneus in a Portuguese population]. / Valores de referência para uma população urbana Portuguesa da avaliação quantitativa por ultrasons do calcâneo.

BACKGROUND: Quantitative ultrasound (QUS) measurement of the calcaneus is a safe and reliable method for evaluating skeletal status. Although central bone densitometry (DXA) measurement is the gold-standard to classify osteopenic and osteoporotic patients, QUS can give supplementary information and its use is expanding. Up to now there are no published normative data for QUS measurements in the Portuguese population. OBJECTIVES: The aims of this study were to determine normative QUS data in the Sahara Clinical Sonometer (Hologic) for the Portuguese population. METHODS: Cross-sectional evaluation of consecutive subjects selected as part of the EpiPorto study, Portugal. Calcaneus QUS (Sahara Clinical Sonometer, Hologic) parameters were obtained: Broadband Ultrasound Attenuation (BUA), Speed of Sound (SOS), Quantitative Ultrasound Index (QUI) and Estimated Bone Mineral Density (EBMD) were determined for men and women, stratified by their age group. RESULTS: 1,482 consecutive subjects (1,010 females and 472 males), aged from 18 to 92 years. Higher levels of QUS parameters were found in the lower age group and, for both gender, progressive decrease with age were reported. Men showed higher values as compared to women in all parameters and differences between them increased with age. Differences were significant for BUA after the age of 39 and for SOS after the age of 59. Short-term in vivo precision was 5.5% for BUA and 0.4% for SOS, while in vitro precision was 3.23% for BUA and 0.15% for SOS. DISCUSSION: Our data are comparable to other Southern European data and represent the first QUS normative data for the Portuguese population.
