BACKGROUND: Botulinum toxin A treatment involves injecting botulinum toxin A to relax muscle spasticity. Using ultrasonography, this study examined changes in the muscle architecture before and after treatment to evaluate the influence of botulinum toxin A injection on muscles. METHODS: The participants included 18 children (mean age, 6.2 years) with cerebral palsy who were treated with botulinum toxin A for lower extremity spasticity and 27 healthy children (mean age, 6...

Background: Muscle activity contributes to the enhancement of facial aging deformity, blepharospasm, cerebral palsy spasticity, trismus, torticollis, and other conditions. Myotomy of the involved muscles in order to reduce the deformity has variable success rates due to muscle healing and regeneration of activity. Objectives: The goal of this study was to investigate whether blocking striated muscle activity with Botulinum toxin (BtxA) during the healing time after myotomy alters the healing process and reduces long-term muscle activity...

Different eponyms such as "Wood syndrome," Meige syndrome, "Brueghel syndrome," "Blepharospasm plus syndrome" have been used to describe segmental craniocervical dystonias. These facial and/or oromandibular movement disorders are characterized by muscle contractions and spasms involving eyes, facial region, and sometimes pharynx, jaw, floor of the mouth, and tongue. The pathophysiology of craniocervical dystonia is poorly understood, but abnormal plasticity and impaired inhibition are suspected. Injection of botulinum toxin appears to be the best therapeutic option for treating segmental craniocervical dystonia...

BACKGROUND: Treatment for patients with chronic low-back pain (LBP) is a public health issue. Intramuscular injections of botulinum toxin A (BoNT-A) have shown an analgesic effect on LBP in two previous randomized controlled studies. The objective of the study was to verify the efficacy of paravertebral injections of BoNT-A in patients with LBP. METHODS: Patients were included in this phase 3 randomized double-blinded trial comparing the efficacy of BoNT-A versus placebo in a crossover study on LBP...

Botulinum neurotoxins (BoNTs) are the most potent toxins to mammals. A toxoid vaccine was previously used for prevention of botulinum intoxication; however, this vaccine is no longer available. Currently, no approved botulinum vaccines are available from the Food and Drug Administration (FDA). Recently, a recombinant host cell receptor-binding subunit created for use as a potential vaccine completed phase 2 clinical trials. The current study designed a vaccine candidate against BoNT type A (BoNT/A) using a structural design...

Tension-type headache (TTH) is the most common type of chronic recurring head pain. It can occur twice as often in women as in men. It is the most common type of headache. Its lifetime prevalence is 30% to 78% in the general population. TTH treatment should be multilevel. It often consists of taking pain medication, muscle relaxants, antidepressants, using biofeedback therapy, acupuncture, and attending behavioral therapy. Several clinical trials also suggest that botulinum toxin (BTX) may be an effective treatment option for such patients...

OBJECTIVE: To provide family physicians with a practical clinical summary of the Canadian Pain Society (CPS) revised consensus statement on the pharmacologic management of neuropathic pain. QUALITY OF EVIDENCE: A multidisciplinary interest group within the CPS conducted a systematic review of the literature on the current treatments of neuropathic pain in drafting the revised consensus statement. MAIN MESSAGE: Gabapentinoids, tricyclic antidepressants, and serotonin-norepinephrine reuptake inhibitors are the first-line agents for treating neuropathic pain...

Yin-Ting Chen, Keyonna M Jenkins
Ischiofemoral impingement syndrome (IFIS) is a rare and poorly understood condition that leads to deep gluteal pain, groin, and/or medial thigh pain. It has unique diagnostic challenges, with limited non-operative treatment options. It is caused by the impingement of the quadratus femoris by the lesser trochanter and the ischium. Currently there are no validated physical examination maneuvers for IFIS, and the value of ischiofemoral interval for establishing IFIS is also uncertain. Ultrasound-guided corticosteroid injections have been reported...

BACKGROUND: Although botulinum toxin type A (BT-A) is approved for chronic migraine treatment, its site and mechanism of action are still elusive. Recently our group discovered that suppression of CGRP release from dural nerve endings might account for antimigraine action of pericranially injected BT-A. We demonstrated that central antinociceptive effect of BT-A in sciatic region involves endogenous opioid system as well. Here we investigated possible interaction of BT-A with endogenous opioid system within the trigeminal region...

[Purpose] Lower extremity strength is a contributing factor to energy efficiency of gait. However, this contribution has not previously been evaluated in children with hemiplegic cerebral palsy (CP). The aim of this study was to evaluate the association between energy consumption, measured by the physical cost index (PCI), and strength of lower extremity, measured by the maximum knee extensor strength (MKES), in children with hemiplegic CP. [Subjects and Methods] Subjects were 10 children (4 males and 6 females; age, 7-17 years) with hemiplegic CP, but no history of orthopedic intervention or botulinum toxin treatment over the 1 year prior to the assessment...

Clostridium botulinum is an anaerobic sporeforming bacterium that is notorious for producing a potent neurotoxin. Spores of C. botulinum can survive mild food processing treatments and subsequently germinate, multiply, produce toxin and cause botulism. Control of spore germination and outgrowth is therefore essential for the safety of mildly processed foods. However, little is known about the process of spore germination in group II C. botulinum (gIICb), which are a major concern in chilled foods because they are psychrotrophic...

Karuna Dewan, Gerald S Berke
INTRODUCTION: Abductor spasmodic dysphonia, a difficult-to-treat laryngologic condition, is characterized by spasms causing the vocal folds to remain abducted despite efforts to adduct them during phonation. Traditional treatment for abductor spasmodic dysphonia-botulinum toxin injection into the posterior cricoarytenoid muscle-can be both technically challenging and uncomfortable. Due to the difficulty of needle placement, it is often unsuccessful. The purpose of this investigation is to present a previously undescribed treatment for abductor spasmodic dysphonia-bilateral vocal fold medialization...

BACKGROUND: Nerves are key factors in prostate cancer (PCa), but the functional role of innervation in prostate cancer is poorly understood. PCa induced neurogenesis and perineural invasion (PNI), are associated with aggressive disease. METHOD: We denervated rodent prostates chemically and physically, before orthotopically implanting cancer cells. We also performed a human neoadjuvant clinical trial using botulinum toxin type A (Botox) and saline in the same patient, before prostatectomy...

Essential tremor is characterized by persistent, usually bilateral and symmetric, postural or kinetic activation of agonist and antagonist muscles involving either the distal or proximal upper extremity. Quality of life is often affected and one's ability to perform daily tasks becomes impaired. Oral therapies, including propranolol and primidone, can be effective in the management of essential tremor, although adverse effects can limit their use and about 50% of individuals lack response to oral pharmacotherapy...

Background: Botulinum toxin (BoNT) is widely used to treat masseter muscle hypertrophy. Changes in the muscle thickness have been found in many studies, but there has been no report on changes in the thickness from the skin surface to the masseter muscle. Objectives: We aimed to use ultrasonography to measure not only changes in the muscle thickness but also changes in subcutaneous thickness. Methods: This study enrolled 20 volunteer patients: 10 were assigned to an experimental group (injected with each side 25 U of botulinum toxin into both masseter muscles) and 10 to a control group (injected with normal saline)...
