Neurotoxicity induced by lead levels: an electrophysiological study

The object of the present study was to evaluate, with the aid of visual evoked potentials (VEPs), modifications induced in the optic nerve by lead, and to investigate the relationship between blood lead levels (PbB) and modification of the VEP. We studied a sample of 300 men with PbB values between 17 and 60 g/100 ml. Our study demonstrates that alterations in the latency of the VEP are dependent on PbB levels, though there is not a directly proportional relationship.

Creative versus repetitive dance therapies to reduce the impact of fibromyalgia and pain: A systematic review and meta-analysis

Background and purposePhysical exercise is one of the most effective interventions to reduce fibromyalgia symptoms. Previous studies have reported benefits of dance-based intervention on the fibromyalgia impact, health-related quality of life and pain, regardless the interventions were based on creative- or repetitive dance. This study aimed to compare the effectiveness of creative and repetitive dance interventions.MethodsPRISMA guidelines were followed in this systematic review. The Cochrane Library, PubMed, Trip, Google Scholar, Web of Science (WOS), Embase and Scopus databases were selected to identify potential articles. Studies were included if they met the following inclusion criteria: to be a clinical trial or a randomized controlled trial, include people with fibromyalgia, have a comparison group and evaluate the impact of the disease, pain or quality of life. Fifteen articles fulfilled the inclusion criteria. The methodological quality of the studies was assessed using the Cochrane Collaboration's tool.ResultsDance-based interventions significantly reduced fibromyalgia impact (standardized mean difference = −0.69), pain (standardized mean difference = −0.70 and increased quality of life (standardized mean difference = 0.43) of people with fibromyalgia. The effectiveness of dance interventions is increased when a creative component is added, since it can lead to higher improvements in pain, impact of the disease and improving quality of life.ConclusionDance-based interventions are significantly effective in reducing the impact of fibromyalgia, pain as well as increasing health-related quality of life. Subgroup analyses suggest that creative dance-based interventions could be more effective than repetitive dance-based interventions to reduce pain and fibromyalgia impact. However, results must be taken with caution due to the large heterogeneity and the small number of articles.     

Efficacy of myofascial therapy and kinesitherapy in improving function in shoulder pathology with prolonged immobilization: A randomized,single-blind,controlled trial

BackgroundThe best physiotherapeutic approach in shoulder pathology that generates prolonged immobilization is still uncertain. Kinesitherapy remains the most widely used option. Myofascial therapy is a therapeutic approach in which the aim is to release fascial tension and regain mobility although its efficacy in shoulder pathology has not been sufficiently studied. This Prospective, single-blind randomized controlled trial in a university hospital setting aimed to compare the efficacy of myofascial therapy and kinesitherapy in improving function in shoulder pathology with prolonged immobilization.MethodsPatients were randomly assigned to a control group or to the intervention group.Both groups completed a therapeutic exercise program. Main Outcome Measures: The QuickDash questionnaire was the primary outcome, Pain Visual Analog Scale and the Range Of Motion of the shoulder were the secondary outcomes. The outcomes were evaluated at baseline (T0), at 4 (T2), 8 (T2), and 12 weeks (T3)Results44 participants were included. In the analysis of evolution over time, a significant improvement in functionality and range of motion measurements was observed in both groups (p < 0.05), although at 12 weeks only Myofasical Group achieved a clinically and statistically significant reduction in pain. Comparative analysis at 12 weeks revealed no statistically significant differences between the two therapies in the variables explored.ConclusionsBoth, myofascial therapy and kinesitherapy can improve function, mobility, and pain in patients with painful shoulder associated with prolonged immobilization, with no significant differences between therapies, although in the medium term only myofascial therapy achieves a clinically and statistically significant improvement in pain.Trial registrationTrial registration: ClinicalTrials.gov NCT04944446.     

IgG antibodies, chronic bronchitis, and pulmonary function values in farmer's lung patients and matched controls

We measured IgG antibody levels against eight different microbes in farmer's lung (FL) patients an average of 14 years after the first diagnosed episode of FL and in matched controls. The study population consisted of 87 FL patients and 81 control farmers, matched by age, sex, and smoking habits. Clinical studies included the measurement of IgG antibody levels against Absidia corymbifera, Aspergillus umbrosus, A. fumigatus, Humicola grisea, Saccharopolyspora rectivirgula, Penicillium brevicompactum, Rhodotorula glutinis, and Thermoactinomyces vulgaris, in addition to spirometry, pulmonary diffusing capacity (DL(CO)), and the evaluation of chronic bronchitis. Median IgG antibody levels were two or more times higher in FL patients than control farmers against Ab. corymbifera, S. rectivirgula, and T. vulgaris (P<0.001). Against A. fumigatus, H. grisea, and R. glutinis, FL patients also had significantly higher antibody levels. FL patients often had positive antibody titers against several microbes, whereas control farmers usually had a positive titer against one or two microbes. A positive association between IgG antibody levels and chronic bronchitis and DL(CO) was observed in FL patients, but not in control farmers. It is suggested that the high antibody levels noted in FL patients were due not only to high exposure but also to individual sensitivity to environmental microbes.
