INTRODUCTION: Neurotoxin injection is used to treat a wide variety of neuromuscular disorders. The purpose of this study was to measure the functional and structural properties of botulinum toxin-injected adult rat skeletal muscle over nearly the entire lifespan. METHODS: Ten groups of animals were subjected to either neurotoxin injection [Botox, Type A (BT-A); Allergan, Irvine, California] or saline solution injection. Neurotoxin-injected animals (n = 90) were analyzed at different time-points: 1 week; 1 month; 3 months; 6 months; 12 months; or 18 months...

BACKGROUND: Although botulinum neurotoxin (BoNT) injections may alleviate involuntary muscle contractions in hemifacial spasm substantially, it is less clear whether the motor effect would translate into improvements of health-related quality of life (HR-QoL). METHODS: In this open-label clinical observational study, we characterized outcomes on HR-QoL in terms of the EuroQol (EQ-5D-5L) from BoNT in a prospective cohort of patients with hemifacial spasm (n = 73)...

Botulinum toxin is recognised as the gold standard for the treatment of essential blepharospasm and hemifacial spasm, which is similar in effect in synkinesis after facial nerve palsy. The injection intervals can be adjusted according to the patients' needs and be shortened for up to six weeks in cases of eyelid cramping. Newer indications for the use of botulinum toxin in ophthalmology include eyelid retraction in Graves' disease, induction of protective ptosis and treatment of crocodile tears syndrome after facial nerve palsy...

Polycyclic aromatic hydrocarbons (PAHs) are a group of toxic and carcinogenic pollutants that can adversely affect the development, growth and reproduction of marine organisms including copepods. However, knowledge on the molecular mechanisms regulating the response to PAH exposure in marine planktonic copepods is limited. In this study, we investigated the survival and gene expression of the calanoid copepod Pseudodiaptomus poplesia upon exposure to two PAHs, 1, 2-dimethylnaphthalene (1, 2-NAPH) and pyrene...

The treatment of glabellar lines with botulinum toxin type-A (BoNT-A) is a staple for aesthetic providers who specialize in facial rejuvenation. Clinical efforts are currently underway to substantiate upper facial injections (the corrugator muscles are the target muscles) of BoNT-A as an antidepression therapy. This article describes the origin of "facial feedback" by Charles Darwin nearly 150 years ago, as well as "emotional proprioception"-2 neuroanatomical concepts that help provide the scientific rationale behind the general influence facial muscles have on the emotional centers of the brain, and, specifically, how the corrugator muscles-involved with frowning-promote a gloomy mood...

This study aims to investigate the molecular mechanisms of acupuncture in the remission of depression. A depressive disorder model was induced by exposing Sprague-Dawley rats to chronic unpredictable stress. The rats were divided into five groups: healthy (blank group) and stressed rats (model group), and stressed rats treated with acupuncture (acupuncture group), riluzole (riluzole group), acupuncture combined with botulinum toxin A (BTX-A) injection (acupuncture+BTX-A group) or riluzole combined with BTX-A injection (riluzole+BTX-A group)...

Mood, anxiety, and other psychological symptoms are common in dystonic patients suffering from blepharospasm (BSP) and spasmodic torticollis (ST). Since sexual well-being is an important aspect of mental health, here, we investigated whether these patients may also experience a worsening of their sexual life. In particular, quality of sexual life was evaluated in patients suffering from BSP (N = 30), ST (N = 30), and in a control group of patient with Hemifacial spasm (HFS; N = 30), undergoing botulinum toxin type A therapy...

BACKGROUND: Injection of botulinum toxin type A for cosmetic purposes is common. It is believed to be safe, but adverse reactions have been reported, including dysphagia, generalized paralysis, respiratory depression, and death caused by focal injection of the toxin. Early administration of antitoxin in patients with adverse reactions is the mainstay of management, but the time window for its clinical efficacy is not well defined. CASE REPORTS: Two female adult patients with clinical botulism after botulinum toxin type A injection are described...

OBJECTIVE: The therapeutic effects of intramuscular injections of botulinum toxin-type A on spasticity can be largely explained by its blocking action at the neuromuscular junction. BTx-A is assumed also to have a central action by affecting the functional organization of the CNS. The objective was to assess its action on spinal motor networks by investigating the post-activation depression (post-AD) of the soleus H-reflex in post-stroke patients. Post-AD that is a presynaptic mechanism controlling the synaptic efficacy of Ia-motoneuron transmission is involved in the pathophysiology of spasticity...

Serotonin (5-hydroxytryptamine, 5-HT) and brain-derived neurotrophic factor (BDNF) are two signaling molecules that have important regulatory roles in the development and plasticity of neural circuits that are known to be altered in depression. However, the mechanism by which 5-HT regulates BDNF signaling is unknown. In the present study, we found that 5-HT treatment increases BDNF receptor, TrkB (tropomyosin related kinase B), levels in mouse primary cortical neurons via a Rac1 (RAS-related C3 botulinum toxin substrate 1)-dependent mechanism...

BACKGROUND: Cervical dystonia (CD) is characterized by involuntary muscle contractions causing abnormal postures and/or twisting movements of the head and neck. These motor symptoms can have a major impact on disability. Treatment with botulinum toxin injections aims to reduce motor symptoms, and therefore disability. Despite motor improvements, many patients still experience difficulties with performing daily life activities. To optimize treatment, other factors that determine disability should be identified...

AIM: To investigate the efficacy and safety of electromyography (EMG)- and palpation-guided botulinum toxin type A injection in cervical dystonia (CD) patients. METHODS: In this randomized, controlled trial, 68 CD patients were randomly allocated to two groups, receiving botulinum toxin type A injections guided by either palpation (Group A) or EMG (Group B). The primary endpoint is defined as the difference in the Tsui score between groups at 16 weeks. The secondary endpoints were the visual analog scale (VAS) and Hospital Anxiety and Depression Scale (HADS) scores and Clinical and Patient Global Impression of Change (CGIC and PGIC)...

REVIEW
Israel Franco
Overactive bladder (OAB) is a ubiquitous syndrome that is defined by urinary urgency with, or without urinary incontinence. OAB is observed in all parts of the world, with a prevalence of 5-12% in children (5-10 years of age) and a prevalence of 0.5% in older adolescents (16-18 years of age). Published data indicate that around a third of children with OAB are likely to become adults with similar complaints. Studies in children and in adults with OAB indicate that these individuals are more likely to also have anxiety, depression and attention deficit problems, and that appropriate treatment of these comorbidities can often improve the patient's OAB symptoms...

REVIEW
Ruth Lamb, Jonathan D Rohrer, Andrew J Lees, Huw R Morris
There are currently no disease-modifying treatments for progressive supranuclear palsy (PSP) or corticobasal degeneration (CBD), and no approved pharmacological or therapeutic treatments that are effective in controlling their symptoms. The use of most pharmacological treatment options are based on experience in other disorders or from non-randomized historical controls, case series, or expert opinion. Levodopa may provide some improvement in symptoms of Parkinsonism (specifically bradykinesia and rigidity) in PSP and CBD; however, evidence is conflicting and where present, benefits are often negligible and short lived...

We occasionally observe long-term remission of cervical dystonia after several botulinum toxin treatments. However, botulinum toxin transiently acts on neuromuscular junctions. We herein report that a cervical dystonia patient with spinocerebellar ataxia type 1 could have long-term remission as a result of the depression of hypermetabolism in the bilateral putamen and primary sensorimotor cortex after botulinum toxin therapy. We suggest that botulinum toxin impacts the central nervous system, causing prolonged improvement through the normalization of basal ganglia circuits in addition to its effects at neuromuscular junctions...
