RESUMO
BACKGROUND: Musculoskeletal disorders are a leading cause of morbidity and the most prevalent source of disability among soldiers. Their high prevalence in armed forces and limited ressources have led to problems related to access to physical rehabilitation care. To increase access, supervised group-based exercise programs for the most prevalent musculoskeletal disorders (low back pain, patellofemoral pain, rotator cuff-related shoulder pain or lateral ankle sprain) have been developed at a Canadian Armed forces (CAF) base, but their effectiveness has not been evaluated. The primary objective of this randomized controlled trial is to evaluate the mid- and long-term effects of these group-based training programs on pain severity and functional limitations, in comparison with usual individual physiotherapy care. Secondary objectives include comparing both interventions in terms of health-related quality of life, pain-related fear, and patients' satisfaction. METHODS: One hundred and twenty soldiers with a new medical referral for physiotherapy services for one of the four targeted musculoskeletal disorders will be consecutively recruited. They will be randomly assigned to either group-based training program or usual individual physiotherapy care, and will take part in the assigned 12-week intervention. There will be four evaluation sessions over 26 weeks (baseline, week 6, 12 and 26). At each follow-up, functional limitations, pain severity, health-related quality of life and pain-related fears will be assessed. Patients satisfaction with treatment will also be evaluated at the end of the intervention period. Either two-way repeated measures ANOVA will be used to analyse and compare the effects of the interventions. DISCUSSION: This RCT will determine the effectiveness of group-based training programs compared to usual individual physiotherapy care. This new intervention model could represent an efficient, and more pro-active approach to manage a higher number of soldiers with musculoskeletal disorders. It could improve access to physical rehabilitation care and improve the health of soldiers. TRIAL REGISTRATION: ClinicalTrials.gov ( NCT05235152 ), February 11th 2022.

BACKGROUND: Overcrowding in emergency departments (ED) is a major concern worldwide. To answer increasing health care demands, new models of care including advanced practice physiotherapists (APP) have been implemented in EDs. The purpose of this study was to assess diagnostic, treatment and discharge plan concordance between APPs and ED physicians for patients consulting to the ED for minor musculoskeletal disorders (MSKD). METHODS: Patients presenting to two EDs in Montréal (Canada) with a minor MSKD were recruited and independently assessed by an APP and ED physician. Both providers had to formulate diagnosis, treatment and discharge plans. Cohen's kappa (κ) and Prevalence and Bias Adjusted Kappas (PABAK) with associated 95%CI were calculated. Chi Square and t-tests were used to compare treatment, discharge plan modalities and patient satisfaction between providers. RESULTS: One hundred and thirteen participants were recruited, mean age was 50.3 ± 17.4 years old and 51.3% had an atraumatic MSKD. Diagnostic inter-rater agreement between providers was very good (κ = 0.81; 95% CI: 0.72-0.90). In terms of treatment plan, APPs referred significantly more participants to physiotherapy care than ED physicians (κ = 0.27; PABAK = 0.27; 95% CI: 0.07-0.45; p = 0.003). There was a moderate inter-rater agreement (κ = 0.46; PABAK = 0.64; 95% CI: 0.46-0.77) for discharge plans. High patient satisfaction was reported with no significant differences between providers (p = 0.57). CONCLUSION: There was significant agreement between APPs and ED physicians in terms of diagnosis and discharge plans, but more discrepancies regarding treatment plans. These results tend to support the integration of APPs in ED settings, but further prospective evaluation of the efficiency of these types of models is warranted.

BACKGROUND: Advanced practice physiotherapy (APP) models of care where physiotherapists are primary contact emergency department (ED) providers are promising models of care to improve access, alleviate physicians' burden, and offer efficient centered patient care for patients with minor musculoskeletal disorders (MSKD). OBJECTIVES: To compare the effectiveness of an advanced practice physiotherapist (APPT)-led model of care with usual ED physician care for persons presenting with a minor MSKD, in terms of patient-related outcomes, health care resources utilization, and health care costs. METHODS: This trial is a multicenter stepped-wedge cluster randomized controlled trial (RCT) with a cost analysis. Six Canadian EDs (clusters) will be randomized to a treatment sequence where patients will either be managed by an ED APPT or receive usual ED physician care. Seven hundred forty-four adults with a minor MSKD will be recruited. The main outcome measure will be the Brief Pain Inventory Questionnaire. Secondary measures will include validated self-reported disability questionnaires, the EQ-5D-5L, and other health care utilization outcomes such as prescription of imaging tests and medication. Adverse events and re-visits to the ED for the same complaint will also be monitored. Health care costs will be measured from the perspective of the public health care system using time-driven activity-based costing. Outcomes will be collected at inclusion, at ED discharge, and at 4, 12, and 26 weeks following the initial ED visit. Per-protocol and intention-to-treat analyses will be performed using linear mixed models with a random effect for cluster and fixed effect for time. DISCUSSION: MSKD have a significant impact on health care systems. By providing innovative efficient pathways to access care, APP models of care could help relieve pressure in EDs while providing efficient care for adults with MSKD.

This prospective study was done for the comparison of visual inspection using acetic acid (VIA) and Pap smear as a method of cervical cancer screening. This study was also done to determine the proportion of women screened positive with VIA and proportion of women screened positive with Pap smear. Another aim was to compare the sensitivity and specificity of VIA and Pap smear. A total of 300 women attended to the outpatient gynecologic clinic and cervical cancer screening programme at Bangabandhu Sheikh Mujib Medical University (BSMMU) were included. On VIA, 23 out of 300 women screened had aceto-white lesions. On Pap smear, 14 out of the 300 women had ASCUS or worse lesions. Of the 300 enrolled women, 11 were positive on both VIA and cytology; 12 were positive on VIA only; and 3 were positive on cytology only. Those women (n=26) who showed positive test result with either VIA or Pap smear or both tests were further subjected to colposcopy directed biopsy. Histology was taken as gold standard to compare the performance of VIA and cytology (Pap's smear). Histological diagnosis of CIN/cancer was made in 18 Positive cases out of the total 26 patients who underwent biopsy. Pap smear picked up 10 out of the 18 biopsy-proven cases whereas VIA could identify 17 out of the 18 CIN/carcinoma cervices. VIA was more sensitive (94.44%) than pap smear (55.55%), which was statistically significant. However, the specificity of VIA was slightly lower (97.87%) than that of cytology (98.58%). The PPV of VIA was 73.91% versus 71.42 % for Pap smear.

OBJECTIVE: To compare clinical measures of hip abductor strength and endurance of individuals with patellofemoral pain with more severe symptoms to those with less severe symptoms. DESIGN: Cross-sectional. SETTINGS: Laboratory. PARTICIPANTS: Sixty participants with patellofemoral pain were divided three times into 2 groups according to three symptomatology criteria: functional capacity, pain frequency and pain severity. MAIN OUTCOME MEASURES: Isometric strength evaluated using a hand-held dynamometer, endurance using maximum number of repetitions and maximum holding time, functional capacity using the Anterior Knee Pain Scale, pain frequency using a 2-category scale ("Less frequent" = 1-2 times a week; "More frequent" = >3 times a week) and pain severity using Numeric Pain Rating Scales. RESULTS: Participants with more frequent symptoms and with more severe pain were significantly weaker (10%, p = 0.04 and 16%, p = 0.001, respectively), and had less isometric (17%, p = 0.02 and 24%, p = 0.002, respectively) and dynamic (13%, p = 0.02 and 23%, p = 0.007, respectively) endurance compared to those with less pronounced symptoms. CONCLUSION: Our study highlighted that hip abductor strength and endurance deficits are more pronounced in individuals with more severe and frequent pain.

OBJECTIVE: To perform a systematic review on the efficacy of transcutaneous electrical nerve stimulation (TENS) for the treatment of rotator cuff tendinopathy in adults. METHODS: A literature search was conducted in four databases (CINAHL, Embase, PubMed and PeDRO) for randomised controlled trials published from date of inception until April 2015, comparing the efficacy of TENS for the treatment of rotator cuff tendinopathy with placebo or any other intervention. Risk of bias was evaluated using the Cochrane risk of bias tool. Results were summarised qualitatively. RESULTS: Six studies were included in this review. The mean methodological score was 49% (standard deviation 16%), indicating an overall high risk of bias. One placebo-controlled trial reported that a single TENS session provided immediate pain reduction for patients with rotator cuff tendinopathy, but did not follow the participants in the short, medium or long term. Two trials that compared ultrasound therapy with TENS reported discrepancy and contradictory results in terms of pain reduction and shoulder range of motion. Corticosteroid injections were found to be superior to TENS for pain reduction in the short term, but the differences were not clinically important. Other studies included in this review concluded that TENS was not superior to heat or pulsed radiofrequency. CONCLUSION: Due to the limited number of studies and the overall high risk of bias of the studies included in this review, no conclusions can be drawn on the efficacy of TENS for the treatment of rotator cuff tendinopathy. More methodologically sound studies are needed to document the efficacy of TENS. Until then, clinicians should prefer other evidence-based rehabilitation interventions proven to be efficacious to treat patients with rotator cuff tendinopathy.

When subjects learn a novel motor task, several sources of feedback (proprioceptive, visual or auditory) contribute to the performance. Over the past few years, several studies have investigated the role of visual feedback in motor learning, yet evidence remains conflicting. The aim of this study was therefore to investigate the role of online visual feedback (VFb) on the acquisition and retention stages of motor learning associated with training in a reaching task. Thirty healthy subjects made ballistic reaching movements with their dominant arm toward two targets, on 2 consecutive days using a robotized exoskeleton (KINARM). They were randomly assigned to a group with (VFb) or without (NoVFb) VFb of index position during movement. On day 1, the task was performed before (baseline) and during the application of a velocity-dependent resistive force field (adaptation). To assess retention, participants repeated the task with the force field on day 2. Motor learning was characterized by: (1) the final endpoint error (movement accuracy) and (2) the initial angle (iANG) of deviation (motor planning). Even though both groups showed motor adaptation, the NoVFb-group exhibited slower learning and higher final endpoint error than the VFb-group. In some condition, subjects trained without visual feedback used more curved initial trajectories to anticipate for the perturbation. This observation suggests that learning to reach targets in a velocity-dependent resistive force field is possible even when feedback is limited. However, the absence of VFb leads to different strategies that were only apparent when reaching toward the most challenging target.

Previous studies have shown that high levels of MMP-9 can be detected in the serum of patients with various lymphoid malignancies and in leukemia/lymphoma culture supernatants. Indeed, aggressive forms of lymphoma constitutively produce MMP-9 and its elevated levels in the serum or in tissues correlate with advanced stage and poor patient survival. In vitro, MMP-9, which is also produced by the host peritumoral cells in response to the presence of tumors, plays an important role in migration of tumor cells through artificial basement membranes or endothelial cells. In this study, using MMP-9-deficient mice, we show that absence of MMP-9 does not prevent the development of primary T-cell leukemia. Furthermore, MMP-9-deficient cell lines retained their tumorigenic potential, as shown by their ability to induce thymic lymphoma in young syngeneic wild-type animals. In addition, these MMP-9-deficient tumor cells disseminate in normal mice, or mice that are deficient for MMP-9, indicating that tumor growth and dissemination can occur in total absence of MMP-9. These results show for the first time than lymphoma growth can occur in total absence of MMP-9 and have consequences for therapy of invasive cancers with inhibitors of MMPs.

We describe the first human case of lobomycosis caused by Lacazia loboi in a 42-year-old white male resident of Georgia. The patient had traveled to Venezuela 7 years earlier, where he had planned to rappel down Angel Falls in Canaima. Although he never actually rappelled the falls, he did walk under the falls at least three times, exposing himself to the high water pressures of the falls. He noticed a small pustule with surrounding erythema developing on the skin of his right chest wall. The lesion gradually increased in size and had an appearance of a keloid. For cosmetic reasons, the patient sought medical treatment to remove the lesion. After an uncomplicated excision of the lesion, the patient recovered completely. The excised tissue was fixed in formalin for pathologic examination. Tissue sections stained by hematoxylin and eosin, periodic acid-Schiff stain, and Gomori methenamine silver stain procedures showed numerous histiocytes, multinucleated giant cells, and numerous globose or subglobose, lemon-shaped cells producing multiple blastoconidia connected by narrow tube-like connectors and catenate chains of various lengths characteristic of L. loboi.
