Tail-flick test response in 3×Tg-AD mice at early and advanced stages of disease

Publication date: 23 July 2015 Source:Neuroscience Letters, Volume 600 Author(s): Raquel Baeta-Corral , Ruti Defrin , Chagi G. Pick , Lydia Giménez-Llort Despite the impact of pain in cognitive dysfunctions and affective disorders has been largely studied, the research that examines pain dimensions in cognitive impairment or dementia is still scarce. In patients with Alzheimer’s disease (AD) and related dementias, management of pain is challenging. While the sensory-discriminative dimension of pain is preserved, the cognitive-evaluative and the affective-motivational pain dimensions are affected. Due to the complexity of the disease and the poor self-reports, pain is underdiagnosed and undertreated. In confluence with an impaired thermoregulatory behavior, the patients’ ability to confront environmental stressors such as cold temperature can put them at risk of fatal accidental hypothermia. Here, 3xTg-AD mice demonstrate that the sensorial-discriminative threshold to a noxious cold stimulus, as measured by the latency of tail-flicking, was preserved at early and advances stages of disease (7 and 11 month-old, respectively) as compared to age-matched (adulthood and middle aged, respectively) non-transgenic mice (NTg). In both genotypes, the sensory deterioration and poor thermoregulatory behavior associated to age was observed as an increase of tail-flick response and poor sensorimotor performance. At both stages studied, 3xTg-AD mice exhibited BPSD (Behav...

CONCLUSIONS.: Venezuelan migrants who participated in the study reported problems in their QoL; more than two-thirds reported anxiety/depression, and one in six experienced pain/discomfort. The frequency of anxiety/depression was higher in those with university-level education. PMID: 31800929 [PubMed - in process]

Authors: Pessia B, Ciarrocchi A, Marinelli S, Pietroletti R Abstract A young lady complained of the sudden onset of intense chest pain, in consequence of an extreme hyperextension of the back in a yoga position. At endoscopy a large lesion of the esophageal epithelium was detected, involving the middle third of the anterior wall of the esophagus. Other symptoms reported by the patient were dysphagia and odynophagia, depicting the typical features of intramural hematoma, also known as intramural dissection or intramural perforation of the oesophagus. The patient was managed conservatively and symptoms disappeared wi...

Publication date: Available online 5 December 2019Source: Orthopaedics &Traumatology: Surgery &ResearchAuthor(s): Jean-Yves JennyAbstractHip or knee revision for infection requires careful planning of the debridement phase. Bacteriological sample management needs to be planned. Multidisciplinary decisions have to be taken as to 1- or 2-stage strategy, reconstruction technique and soft-tissue management. Surgical resection should be complete while economical. There must be no shortcomings in the technical procedure. Implant removal and surgical debridement are the keys to curing the infection, and planning is essent...

This article reviews the potential role of exosomes in OA regenerative medicine. Special attention is given to mesenchymal stem cells-derived exosomes due to the extensive research on their cartilage repair property and their function as miRNA cargo. More investigations are needed for the effects of exosomes from synovial fluid and chondrocytes in joints. A better understanding of the mechanisms will contribute to a novel and promising therapy for OA patients.

ConclusionWith Metaizeau technique, there were reported poor results of about 10% in literature. In our study, with the modification of the shape of the nail tip, we have managed to achieve stable fixation of the reduction without any loss of position and consequently, better outcomes.

Conclusion. Long-term evidence supports lumbar total disc replacement as safe. The next-generation activL Artificial Disc is more effective at preserving range of motion than first-generation lumbar TDRs (ProDisc-L and Charité) and offers a higher safety profile. Other primary and secondary outcomes are similar between disc designs. Level of Evidence: 2

This study involved 102 patients who underwent indirect decompression at 136 levels, with LLIF and posterior fixation. Magnetic resonance imaging (MRIs) were collected preoperatively and several times postoperatively (over a 2-year period starting immediately after surgery). We then quantified the cross-sectional areas of the thecal sac and ligamentum flavum, as well as the anteroposterior diameter of disc bulging, and qualitatively assessed lumbar spinal stenosis according to a modified version of Schizas’ classification [Grades A (mild) to C (severe)]. The Japanese Orthopaedic Association Back Pain Evaluation Quest...

Study Design. Cross-sectional study. Objective. The aim of this study was to study the personal and societal impact of low back pain (LBP) in patients admitted to a multidisciplinary spine center. Summary of Background Data. The socioeconomic burden of LBP is very high. A minority of patients visit secondary or tertiary care because of severe and long-lasting complaints. This subgroup may account for a major part of disability and costs, yet could potentially gain most from treatment. Currently, little is known about the personal and societal burden in patients with chronic complex LBP visiting secondary/tertiary c...

Study Design. This is an observational cohort study. Objective. The aim of this study was to compare the effectiveness of PT to an interdisciplinary treatment approach in patients with chronic low back pain (CLBP). Summary of Background Data. CLBP is a costly and potentially disabling condition. Physical therapy (PT), cognitive behavioral therapy, and interdisciplinary pain programs (IPPs) are superior to usual care. Empirical evidence is lacking to clearly support one treatment approach over another in patients with CLBP. Methods. One hundred seventeen adult patients who completed an IPP for individuals with &g...

Study Design. Retrospective cohort study. Objective. The aim of this study was to compare clinical and radiographic outcomes of patients who underwent stand-alone lateral lumbar interbody fusion (LLIF) to those who underwent posterolateral fusion (PLF) for symptomatic adjacent segment disease (ASD). Summary of Background Data. Recent studies have suggested that LLIF can successfully treat ASD; however, there are no studies to date that compare LLIF with the traditional open PLF in this cohort. Methods. A total of 47 consecutive patients who underwent LLIF or PLF for symptomatic ASD between January 2007 and Augus...
