Botulinum neurotoxins are diverse proteins. They are currently represented by at least seven serotypes and more than 40 subtypes. New clostridial strains that produce novel neurotoxin variants are being identified with increasing frequency, which presents challenges when organizing the nomenclature surrounding these neurotoxins. Worldwide, researchers are faced with the possibility that toxins having identical sequences may be given different designations or novel toxins having unique sequences may be given the same designations on publication...

Scar contracture deformity, which can lead to dysfunction of hand and low quality of life, is one of the common complication after hand burns. The prevention measures of scar contracture after hand burns include large skin grafting, prevention of infection, insistence on wearing pressure gloves, use of silicone sheets, wearing orthosis, accepting proper physical therapy, and early functional exercise. The primary treatments of postburn contractures of the hand are surgery, drugs, laser treatment, and rehabilitation therapy...

BACKGROUND: The treatment of achalasia is palliative. Pneumatic dilatation (PD) or laparoscopic Heller myotomy (LHM) just eliminates the outflow obstruction allowing easier emptying of the esophagus. The aim of this study was to evaluate the results of a multidisciplinary approach to esophageal achalasia. MATERIALS AND METHODS: A consecutive series of patients with achalasia treated by a multidisciplinary esophageal team consisting of radiologists, gastroenterologists, and surgeons in a quaternary care center between May 2008 and April 2015 were analyzed...

BACKGROUND: While primary hyperhidrosis can be seen in men, accompanying hot flushes is rarely seen in men. Primary hyperhidrosis is thought to be related to overactivity of the sympathetic nervous system while hot flushes are believed to be related to altered peripheral vascular reactivity and a narrowed thermoregulatory zone. CASE PRESENTATION: I report the case of a 29-year-old man of Arab origin who presented to a dermatology clinic with a complaint of generalized sweating, with heavier involvement of his inguinal region, axilla, and lower back...

Posterior drooling, which can lead to substantial respiratory morbidity, including unexplained lung diseases and recurrent pneumonia, is an important issue in the rehabilitation unit. There are various treatment options for posterior drooling, including pharmacologic therapy, oral motor or behavioral therapy, biofeedback, local glandular injection of botulinum toxin, irradiation, and surgery. Among them, nebulized glycopyrrolate has the following advantages: It is noninvasive and is relatively free of central adverse effects because it does not cross the blood-brain barrier unlike other anticholinergics...

Sialorrhea in children with cerebral palsy (CP) results in aspiration, decreased social integration, and poor quality of life. Management options include transdermal anticholinergics such as the scopolamine patch. A controlled clinical trial has proven botulinum toxin (BTX) injections into the salivary glands are an effective alternative to transdermal anticholinergics with a safer side effect profile. Multiple studies of the injections in diverse populations demonstrate reduction in saliva production with improvement in quality of life and decrease in hospitalization-associated costs...

Today, botulinum toxin is commonly used for cosmetic purposes throughout the world. Despite various agents reducing the efficiency of toxin are well defined, the studies related to increasing the bioavailability are limited. The purpose of our study is to assess the effect of the preparation of toxin by diluting with platelet-poor plasma (PPP) and/or albumin instead of standard dilution (saline) on bioavailability in cosmetic-purpose botulinum toxin applications.In the study, 24 New Zealand rabbits were used...

BACKGROUND: Many centers use botulinum toxin for chemical pyloroplasty in minimally invasive esophagectomies as prophylaxis against delayed gastric emptying. No previous studies have compared botulinum toxin injection with no pyloric intervention for patients treated with a combined laparoscopic and thoracoscopic approach. The authors hypothesized that chemical pyloroplasty does not improve outcomes for these patients. METHODS: The study investigated patients undergoing minimally invasive esophagectomies from September 2009 to June 2015...

The small GTPase Ras-related C3 botulinum toxin substrate 1 (RAC1) plays a central role in skin homeostasis, including barrier function, wound healing and inflammatory responses. Psoriasis is a common skin disease characterized by deregulation of these functions, and affected skin exhibit keratinocyte hyperproliferation, inflammation and immune cell infiltration. Although psoriasis is often triggered by environmental stimulus, there is a strong genetic association with genes expressed in both immune cells and keratinocytes, of which several are linked to Rac1 signaling...

Aim of this study is to identify factors contributing the occurrence of neck lateral shift (LS) in patients with cervical dystonia (CD). A retrospective analysis focused on the treatment with botulinum toxin (BTX) was conducted on 38 consecutive idiopathic CD patients comparing subjects with and without LS. The main result was the evidence of a significantly higher BTX inter-side dose difference in patients with LS suggesting that this uncommon phenotype may be an artifact of chronic therapy with BTX.

Emel Başar, Ceyhun Arıcı
Botulinum neurotoxin (BoNT) is the first biological toxin used in the treatment of ophthalmic diseases and to decrease skin wrinkles as an aesthetic agent. When used appropriately, it weakens the force of muscular contraction and/or inhibits glandular secretion. The most common areas for botulinum toxin treatment are the upper face, including the glabella, forehead, brows, and lateral canthal lines, or crow's feet. By relaxing the muscles causing wrinkles, non-permanent results may be achieved with its use...

Chronic pelvic pain is a frustrating symptom for patients with endometriosis and is frequently refractory to hormonal and surgical management. While these therapies target ectopic endometrial lesions, they do not directly address pain due to central sensitization of the nervous system and myofascial dysfunction, which can continue to generate pain from myofascial trigger points even after traditional treatments are optimized. This article provides a background for understanding how endometriosis facilitates remodeling of neural networks, contributing to sensitization and generation of myofascial trigger points...
