Muscle Spasms

(no author information available yet)
Tetanus is an acute specific infection caused by obligate anaerobes, which is still a serious public health problem. Tetanus bacterium is an obligate anaerobic bacterium, widely distributed in nature, which can exist in dust, soil, human or animal excrement. The bacteria invade the body primarily through the skin or mucosal wounds, and most commonly in trauma and burn patients, unclean newborns, and unsafe surgical instruments. Exotoxin produced by tetanus bacteria can cause temporary changes in the central nervous system, manifested as systemic skeletal muscle persistence and paroxysmal spasm, severe cases of laryngospasm, asphyxia, lung infections and organ failure, which is a very serious and potentially fatal disease...

Due to the paucity of evidence, this study was conducted to evaluate: (1) unique characteristics of multiple sclerosis (MS) patients and (2) short-term clinical outcomes, of primary total knee arthroplasty (TKA) in patients with MS (MS-TKA) compared with matched non-MS patients. MS patients who underwent TKA were identified using the Nationwide Inpatient Sample (NIS) database. The study sample consisted of 10,884 patients with MS and 56,45,227 control cohort. Various patient factors were compared. To control for potential confounders, with the use of propensity scores, MS-TKA patients were matched (1:3) to non-MS-TKA patients and regression analyses were performed to compare perioperative complications, length of stay (LOS), and discharge dispositions...

Botulinum toxin has gained immense popularity since its introduction for therapeutic use. It is used in a variety of movement disorders like hemi-facial spasm, focal dystonias like blepharospasm, cervical dystonia, oromandibular dystonia, limb dystonias. It is also being used in patients with tremors, tics and for a variety of indications in Parkinson's disease as well. There are eight subtypes of toxins available, but type A and B are the ones used in movement disorder clinics. The toxin mainly acts by inhibiting the release of acetylcholine at the neuromuscular junction and causing weakness...

In a 59-year-old woman with a perforating eyeball injury to the right eye, the emergency physician induced a preclinical general anesthesia with propofol, fentanyl and the depolarizing muscle relaxant succinylcholine. Anesthesia was maintained using propofol and remifentanil infusion throughout the preoperative period and the subsequent surgical procedure. Postoperatively, isolated rhabdomyolysis with an increase in serum creatine kinase to >20,000 U/l was observed. The diagnosis of malignant hyperthermia (MH) susceptibility could be confirmed in the patient 4 months after the acute event by the in vitro contracture test and detection of the MH causative mutation p...

Studies indicate that 5-hydroxytryptamine (5-HT) released from activated platelets in coronary artery bypass grafting (CABG) induces 5-HT2A receptor-mediated graft spasm. We previously reported that 5-HT-induced constriction of human endothelium-denuded saphenous vein (SV) was significantly augmented in patients with diabetes mellitus (DM) than in patients without DM (non-DM), without changes in the levels of the membrane-bound 5-HT2A receptor of their smooth muscle cells. Although the internal thoracic artery (ITA) is the key graft conduit for CABG, the effect of DM on the ITA graft spasm is still unclear...

Spasticity is a symptom occurring in many neurological conditions including stroke, multiple sclerosis, hypoxic brain damage, traumatic brain injury, tumours and heredodegenerative diseases. It affects large numbers of patients and may cause major disability. So far, spasticity has merely been described as part of the upper motor neurone syndrome or defined in a narrowed neurophysiological sense. This consensus organised by IAB-Interdisciplinary Working Group Movement Disorders wants to provide a brief and practical new definition of spasticity-for the first time-based on its various forms of muscle hyperactivity as described in the current movement disorders terminology...

Background: Linear scleroderma has been associated with muscle spasms ipsilateral to skin lesions. Typically, spasms are located in trigeminal innervated muscles, leading to hemimasticatory spasm (HMS). Case Report: We report a case of linear scleroderma associated with spasm of muscles innervated not only by the trigeminal but also by the facial nerve. Discussion: We review the patient's successful treatment with incobotulinumtoxinA, a formulation of botulinum toxin that has not been reported for use in this condition...

Smoothened inhibitors (SIs) are a new, targeted therapy for the treatment of advanced basal cell carcinoma (BCC), but their usage is significantly limited by the most common side effect, muscle spasms. Muscle spasms affect up to 80% of users, and are the most common reason for drug discontinuation despite tumor response. Currently, no placebo-controlled trials exist to guide the management of vismodegib-related muscle spasms. The medical literature suggests that the naturally occurring substance, levocarnitine (LC), can improve contractile function of muscle and reduce markers of exercise-induced stress...

Peroral endoscopic myotomy (POEM) has been established as an optional treatment for achalasia. POEM is an endoluminal procedure that involves dissection of esophageal muscle fibers followed by submucosal tunneling. Inoue first attempted to use POEM for the treatment of achalasia in humans. Expanded indications of POEM include classic indications such as type I, type II, type III achalasia, failed prior treatments, including Botulinum toxin injection, endoscopic balloon dilation, laparoscopic Heller myotomy, and hypertensive motor disorders such as diffuse esophageal spasm, jackhammer esophagus...

Coronary artery spasm (CAS) is a pathophysiological phenomenon that may cause myocardial infarction and lead to circulatory collapse and death. Aberrant endoplasmic reticulum (ER) stress causes accumulation of misfolding proteins and has been reported to be involved in a variety of vascular diseases. The present study investigated the role of ER stress in the development of CAS and explored the possible molecular mechanisms. Initially, it was found that ER stress markers were elevated in response to drug-induced vascular smooth muscle cells (VSMCs) contraction...
