The subacromial syndrome is the most common source of shoulder pain. The mainstays of conservative treatment are non-steroidal anti-inflammatory drugs and exercise therapy. Recently, low-level laser therapy (LLLT) has been popularized in the treatment of various musculoskeletal disorders. The aim of this study is to evaluate the additive effects of LLLT with exercise in comparison with exercise therapy alone in treatment of the subacromial syndrome. We conducted a randomised clinical study of 80 patients who presented to clinic with subacromial syndrome (rotator cuff and biceps tendinitis). Patients were randomly allocated into two groups. In group I (n = 40), patients were given laser treatment (pulsed infrared laser) and exercise therapy for ten sessions during a period of 2 weeks. In group II (n = 40), placebo laser and the same exercise therapy were given for the same period. Patients were evaluated for the pain with visual analogue scale (VAS) and shoulder range of motion (ROM) in an active and passive movement of flexion, abduction and external rotation before and after treatment. In both groups, significant post-treatment improvements were achieved in all parameters (P = 0.00). In comparison between the two groups, a significant improvement was noted in all movements in group I (P = 0.00). Also, there was a substantial difference between the groups in VAS scores (P = 0.00) which showed significant pain reduction in group I. This study indicates that LLLT combined exercise is more effective than exercise therapy alone in relieving pain and in improving the shoulder ROM in patients with subacromial syndrome.
The Severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) created a global pandemic that continues to this day. In addition to pulmonary symptoms, the virus can have destructive effects on other organs, especially the heart. For example, large pericardial effusion has been observed as a critical and life-threatening finding in Coronavirus disease of 2019 (COVID-19) patients. In this case report based systematic review, we review the reports of moderate to severe pericardial effusion associated with tamponade physiology. Direct cardiomyocyte and pericardium invasion, inflammation and cytokine storms and oxidative stress due to acute respiratory distress syndrome (ARDS), are the pathogenesis of this phenomenon. The results showed that the manifestations of this finding are variable. Pericardial effusion can be seen as a delayed complication, accompanied by myocarditis or pericarditis, isolated, or with ARDS. In most patients, emergency percutaneous pericardiocentesis was performed, and fluid analysis was often exudative in three pattern of hemorrhagic, serous, and serosanguinous. Medical treatment and follow-up are recommended, especially in cases of pericarditis.
As the COVID-19 pandemic continues, more information on the non-respiratory effects of the coronavirus is obtained. Cardiovascular complications, especially acute coronary syndromes, are rare. However, they prove to be effective factors in the mortality rate of COVID-19 subjects. Acute ST-elevation myocardial infarction with a special angiographic pattern in the form of extensive and multi-vessel thrombosis, regardless of atherosclerotic plaques, has posed a new therapeutic challenge. This has been associated with an increase in the incidence of stent thrombosis. Hypercoagulation, due to severe inflammation, is the main pathology of this phenomenon. Technically, percutaneous coronary intervention with aspiration thrombectomy and injectable antiplatelet are the mainstay of treatment for these patients. In addition, it is vital that appropriate antiplatelet and ischemia treatment after the intervention be taken into account.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
