There are currently no functional neuromuscular junction (hNMJ) systems composed of human cells that could be used for drug evaluations or toxicity testing in vitro. These systems are needed to evaluate NMJs for diseases such as amyotrophic lateral sclerosis, spinal muscular atrophy or other neurodegenerative diseases or injury states. There are certainly no model systems, animal or human, that allows for isolated treatment of motoneurons or muscle capable of generating dose response curves to evaluate pharmacological activity of these highly specialized functional units...

An intramuscular formulation of onabotulinumtoxinA (onabotA; Botox® ) is currently the only therapy specifically approved for the prevention of headaches in adults with chronic migraine (CM) in the EU and North America. This article provides a narrative review of relevant data on the drug in this indication from an EU perspective. OnabotA was originally approved on the basis of pooled data from two phase III studies (PREEMPT 1 and 2). In these pivotal studies, injection of up to five cycles of onabotA (155-195 U/cycle) at 12-week intervals was generally well tolerated and effective in producing statistically significant and clinically meaningful improvements in headache symptoms, acute headache pain medication usage, headache impact and health-related quality of life in adults with CM, of whom approximately two-thirds were acute medication overusers and approximately one-third had failed to respond to ≥ 3 prior oral prophylactic therapies...

BACKGROUND: Vocal fold (VF) scarring remains a therapeutic dilemma and challenge in modern laryngology. To facilitate corresponding research, we aimed to establish an in vitro fibrogenesis model employing human VF fibroblasts (hVFF) and the principles of macromolecular crowding (MMC). METHODS: Fibrogenesis was promoted by addition of transforming growth factor-β1 to standard medium and medium containing inert macromolecules (MMC). Hepatocyte growth factor (HGF) and Botox type A were tested for their antifibrotic properties in various doses...

Background: Upper eyelid dermatochalasis often triggers frontalis hyperactivity in an effort to elevate the upper lids away from the visual axis. Similarly, prior neuromodulator treatment of the brow depressors may cause false elevation of the brows, diminishing the extent of preoperative brow ptosis or dermatochalasis. Studies have quantified postoperative brow ptosis and recurrent dermatochalasis following upper blepharoplasty, but a methodology to predict the postoperative brow position remains to be elucidated...

BACKGROUND AND OBJECTIVES: Children with cerebral palsy (CP) are routinely treated with botulinum toxin A (BoNT-A). Two non dose-equivalent and differently priced products, Botox and Dysport are used. Depending on the conversion one of the products is considerably cheaper. However, the dose conversion factors studied to date have varied widely and relevant studies have not included children. Our objective here was to compare the efficacy and health economics of the switch from Botox to Dysport in children with CP when conversion was set to 1:2...

Cyclic strabismus is a rare disease of unknown origin. If untreated, it leads to manifest strabismus with the risk of amblyopia in children. Treatment is generally surgical. Here we report on three children in whom cyclic esotropia was successfully treated with one bimedial injection of 5 IU Botox ® . All patients remained orthotropic with good stereo functions at the last follow-ups at 16, 11, and 8 months. Botulinum toxin offered a minimally invasive treatment option in these patients.

Esophageal achalasia is a primary smooth muscle motility disorder specified by aperistalsis of the tubular esophagus in combination with a poorly relaxing and occasionally hypertensive lower esophageal sphincter (LES). These changes occur secondary to the destruction of the neural network coordinating esophageal peristalsis and LES relaxation (plexus myentericus). There are limited data on segmental involvement of the esophagus in adults. We report on the case of a 54-year-old man who presented initially with complete aperistalsis limited to the distal esophagus...

Botulinum toxin (BoNT) is a neurotoxin produced by the bacteria Clostridium botulinum that has become widely used for various neurologic indications. The four toxin formulations currently available for use in the United States (approved by the Food and Drug Administration) are onabotulinumtoxinA (Botox® ), abobotulinumtoxinA (Dysport® ), incobotulinumtoxinA (Xeomin® ), and rimabotulinumtoxinB (Myobloc® ). While the FDA-approved labels indicate that potency conversions should not be done, literature supports relative dose equivalents of approximately 1:1:2-4:50-100, respectively...

BACKGROUND: It has been generally speculated that paraspinal muscle weakness is related to the spinal degeneration including intervertebral disc failure. The purpose of this study was to investigate the effects of paraspinal muscle weakness induced by the botulinum toxin type-A on the lumbar spine and behavior pattern in an in-vivo primate model which has an upright locomotion similar to that of humans. METHODS: Botox injections into paraspinal muscle of one cynomolgus monkey were conducted biweekly up to 19 weeks at L2-L3, L3-L4 and L4-L5...

Effusions are common among patients with disorders of the temporomandibular joint (TMJ), but publications are limited and results inconsistent about the correlation between them and important clinical variables, in particular severity of pain and degenerative disease. We organised a retrospective study of patients who presented for the evaluation and management of arthralgia of the TMJ and myofascial pain at the University of Michigan between 2011 and 2014. Inclusion criteria were: patients who had pain that was primarily arthrogenous, and coexisting myogenous pain, who had had initial non-surgical treatment, and arthroscopy of the TMJ with or without intramuscular injection of onabotulinumtoxinA (Botox,® Allegan, Weston, Fl, USA)...

Background: Sialorrhoea and drooling are disabling manifestations of different neurological disorders. The aim of this study was to evaluate the effects of botulinum neurotoxin type A (BoNT/A) injection on hypersalivation in 90 patients with neurological diseases of different aetiologies, and to define the minimum number of injected salivary glands to reduce sialorrhoea. Determining the minimum number of glands that need to be engaged in order to have a significant reduction in drooling may be very useful for establishing the minimum total dosage of BoNT/A that may be considered effective in the treatment of hypersalivation...

PURPOSE: In the present study, we investigated the treatment efficacy and clinical outcomes of botulinum neurotoxin-A (BoNT-A) administered for longer than 5 years to patients with essential blepharospasm. METHODS: We retrospectively reviewed 19 patients (male : female = 8 : 11) diagnosed with essential blepharospasm between March 2006 and July 2016 who underwent BoNT-A injections for over 5 years and were followed. Efficacy of 297 injections of Botox (n = 162), Meditoxin (n = 75), Hugel-tox (n = 40), or Dysport (n = 20) was based on the symptom improvement score at the final injection (-1, worse; 0, same; 1, better)...

Wrinkles can have a negative effect on quality of life and Botox is one of the most effective and common treatments. Argireline (Arg0), a mimetic of Botox, has been found to be safer than Botox and effective in reducing wrinkles, with efficacies up to 48% upon 4 weeks of twice daily treatment. However, the skin permeation of Arg0 is poor, due to its large molecular weight and hydrophilicity. Arg0 exists in zwitterionic form and this charged state hindered its skin permeation. Chemical modification of the peptide structure to reduce the formation of zwitterions may result in increased skin permeability...
