Pediatric acute compartment syndrome (PACS) is a clinical entity that must be carefully differentiated from the adult version (ie, acute compartment syndrome). Healthcare providers must understand the variable etiologies of PACS, of which trauma is the most common but can also include vascular insult, infection, surgical positioning, neonatal phenomena, overexertion, and snake and insect bites. In addition to the unique etiologies of PACS, providers must also recognize the different signs and symptoms of PACS...

Bothrops atrox snakes are the leading cause of snake bites in Northern Brazil. The venom of this snake is not included in the antigen pool used to obtain the Bothrops antivenom. There are discrepancies in reports on the effectiveness of this antivenom to treat victims bitten by B. atrox snakes. However, these studies were performed using a pre-incubation of the venom with the antivenom and, thus, did not simulate a true case of envenomation treatment. In addition, the local lesions induced by Bothrops venoms are not well resolved by antivenom therapy...

Sickle cell disease (SCD) is a hereditary red cell disorder with clinical manifestations secondary to sickling or crescent shaped distortion of the red blood cells. Major clinical manifestations of sickle cell disease include hemolytic anemia and vaso-occlusive phenomena resulting in ischemic tissue injury and organ damage. Chronic sequelae of the anemia and vaso-occlusive processes involving the musculoskeletal system include complications related to extramedullary hematopoiesis, osteonecrosis, myonecrosis, and osteomyelitis...

Increased levels of the inflammatory biomarker high-sensitivity C-reactive protein predict cardiovascular events. Pre-Percutaneoues coronary intervention (PCI) plasma hs-CRP concentration has been reported to influence both short and long term outcome after percutaneoues coronary intervention (PCI). Studies have reported association between pre-PCI CRP and PCI induced cardiac myonecrosis evaluated by sensitive marker of myocardial injury. The present study attempts to evaluate the influence of pre-PCI CRP levels, factors related to the procedure and ongoing medications on the event of post-PCI cardiac myonecrosis...

BACKGROUND: Intravenous contrast-enhanced ultrasonography is a recently developed technique for assessment of tissue perfusion, but has not been used for assessment of skeletal muscle perfusion. METHODS: We studied a 42-year-old woman in whom myonecrosis was suspected due to systemic vasculitis and ischemia. The biceps brachii (right) and quadriceps femoris (vastus medialis) on right-hand side and subsequently left-hand side were imaged. Intravenous bolus of activated perflutren lipid microspheres was injected and B-Flow color mode (brown color) was used within a selected region of interest to image the passage of contrast through muscle parenchyma throughout three cardiac cycles...

The shrimp farming has been converted into a mature aquaculture industry dealing with over millions of metric tonnes of processed commodities. Nevertheless, the global shrimp productions are constantly threatened by disease outbreaks, mainly triggered by rapidly disseminating viruses. Infectious myonecrosis virus (IMNV) is one of these epizootic agents affecting shrimp production in Brazil, of which no treatment exists. Herein, the antiviral activity against IMNV of an eicosapeptide, named Ctn[15-34], derived from a member of the cathelicidin family of antimicrobial peptides, was demonstrated...

Myonecrosis after coronary artery bypass graft (CABG) surgery is associated with excess mortality. Tranexamic acid (TA), an anti-fibrinolytic agent, has been shown to reduce peri-operative blood loss without increasing the risk of myocardial infarction (MI); however, no large study has examined the association between TA treatment and post-CABG myonecrosis. In the MC-1 to Eliminate Necrosis and Damage in Coronary Artery Bypass Graft Surgery II trial, inverse probability weighting of the propensity to receive TA was used to test for differences among the 656 patients receiving and 770 patients not receiving TA...

BACKGROUND: Because of its long-lasting analgesic action, bupivacaine is an anesthetic used for peripheral nerve block and relief of postoperative pain. Muscle degeneration and neurotoxicity are its main limitations. There is strong evidence that low-level laser therapy (LLLT) assists in muscle and nerve repair. The authors evaluated the effects of a Gallium Arsenide laser (GaAs), on the regeneration of muscle fibers of the sternomastoid muscle and accessory nerve after injection of bupivacaine...

Bioactive peptide research has experienced considerable therapeutic interest owing to varied physiological functions, efficacy in excretion, and tolerability of peptides. Colostrum is a rich natural source of bioactive peptides with many properties elucidated such as anti-thrombotic, anti-hypertensive, opioid, immunomodulatory, etc. In this study, a variant peptide derived from β-lactoglobulin from buffalo colostrum was evaluated for the anti-ophidian property by targeting snake venom metalloproteinases. These are responsible for rapid local tissue damages that develop after snakebite such as edema, hemorrhage, myonecrosis, and extracellular matrix degradation...

The authors report a case of necrotizing Sweet syndrome in a 24-year-old transsexual male who presented with recurrent myonecrosis of the neck/upper chest. On index admission, computer tomography revealed gas and fat stranding of the sternocleidomastoid and pectoralis major muscle-findings suggestive of a necrotizing soft tissue infection. Despite debridement procedures and intravenous antibiotic therapy, myonecrosis of the affected areas persisted. Evaluation of tissue samples by dermatopathology revealed neutrophilic infiltration extending into the dermis and muscle necrosis, findings consistent with necrotizing Sweet syndrome...

BACKGROUND Myonecrosis is one of the more poorly studied, painful manifestations of sickle cell crisis. Medical literature is sparse detailing the manifestations and management of such symptoms. In myonecrosis, red cells containing sickle hemoglobin become rigid, resulting in reduced blood flow and myonecrosis. CASE REPORT We present a case study of a patient in sickle cell crisis with an episode of acute pain and swelling to the intrinsic muscles of the foot as a prominent feature of the crises. Although muscle biopsy is considered the gold standard for the diagnosis of myositis or myonecrosis, a low intensity signal on T1 and high intensity signal on T2 at the affected muscle belly can be as conclusive as imaging studies...

Clostridium chauvoei is the etiological agent of blackleg, a severe disease of domestic ruminants, causing myonecrosis and serious toxemia with high mortality. Despite the known importance of this agent, studies evaluating its pathogenesis of blackleg are scarce, and many are based on an unproven hypothesis that states that macrophages are responsible for carrying C. chauvoei spores from the intestines to muscles in the early stages of blackleg. Therefore, the present study aimed to investigate the survival of C...

The polysaccharide extract of Momordica charantia has various biological activities; however, its effect on endothelial dysfunction in myocardial infarction remains unclear. To elucidate this, myocardial infarction was induced in rats using isoproterenol (ISP). Pretreatment with M. charantia polysaccharides (MCP; 150 or 300mg/kg) for 25days significantly inhibited increases in heart weight, the heart-weight-to-body-weight ratio, and infarction size, and ameliorated the increased serum levels of aspartate transaminase, creatine kinase, lactate dehydrogenase, total cholesterol, triglycerides, very-low-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol...

BACKGROUND: Local anesthetics are used to relieve pre- and postoperative pain, acting on both sodium channels and nicotinic acetylcholine receptors (nAChR) at the neuromuscular junction (NMJ). Bupivacaine acts as a non-competitive antagonist and has limitations, such as myotoxicity, neurotoxicity, and inflammation. Low-level laser therapy (LLLT) has anti-inflammatory, regenerative, and analgesic effects. The aim of the present study was to evaluate the effects of a gallium arsenide laser (GaAs) on the morphology of the NMJ and nAChRs after application of bupivacaine in the sternomastoid muscle...

BACKGROUND Diabetic myonecrosis is an uncommon complication of long-standing poorly controlled diabetes mellitus. It presents as acute non-traumatic swelling and pain of the lower extremity, which can mimic deep vein thrombosis (DVT). The clinical course is usually self-limiting and patients respond well to supportive medical therapy. CASE REPORT A 54-year-old male with past medical history of poorly controlled diabetes mellitus type II, hyperlipidemia, gastroesophageal reflux disease (GERD), and remote history of DVT presented to our emergency department with 2-week history of progressively worsening left calf pain and swelling...

Reperfusion of the heart after an ischemic insult may lead to potentially lethal arrhythmias and cardimyocyte cell death via apoptosis and necrosis. In addition, previous studies showed that calcium channel blockers may have a protective role in the myocardium against arrhythmia and irreversible tissue injury. Therefore, this study was aimed to investigate the effects of mebudipine on myocardial arrhythmias and tissue injury induced by ischemia/reperfusion injury in isolated rat hearts. Male Wistar rats (250‑300g) were randomly divided to Sham group (without ischemia), control group (ischemia without drug), drug group (ischemia with mebudipine 0...
