Preoperative preparation of «loss of domain» hernia. Progressive pneumoperitoneum and botulinum toxin type A.
2017
Preoperative progressive pneumoperitoneum and botulinum toxin type A are useful tools in the preparation of patients with loss of domain hernias. Both procedures are complementary in the surgical repair, especially with the use of prosthetic techniques without tension, that allow a integral management of these patients. The aim of this paper is to update concepts related to both procedures, emphasizing the advantages that take place in the preoperative management of loss of domain hernias.
Salivary gland application of botulinum toxin for the treatment of sialorrhea
2007
Sialorrhea or excessive salivation, and drooling, are common and disabling manifestations in different neurological disorders. A review is made of the literature, based on a PubMed search, selecting those articles describing clinical trials involving the injection of botulinum toxin A in the salivary glands of patients with different diseases characterized by sialorrhea. The most frequently treated diseases were infant cerebral palsy (30%), Parkinson’s disease (20%) and amyotrophic lateral sclerosis (15%). Over half of the authors injected the product into the parotid glands, 9.5% into the submaxillary glands, and 38% into both. The total doses of toxin injected varied from 10-100 units of …
Évaluation des risques relatifs aux mesures de décontamination et de gestion des sous-produits animaux lors des cas de botulisme bovin et aviaire
2022
Le botulisme est une maladie neurologique humaine et animale, le plus souvent d’origine alimentaire, provoquée par l’action de neurotoxines bactériennes (toxines botuliques) produites par la bactérie Clostridium botulinum et qui se manifeste par une paralysie flasque pouvant aller jusqu’à la paralysie respiratoire et l’arrêt cardiaque. Neuf types toxiniques, répartis en une quarantaine de sous-types, sont actuellement connus.En France, le botulisme animal affecte essentiellement les oiseaux (sauvages et domestiques) et les bovins. Chez les volailles, on recense annuellement vingt à trente foyers, majoritairement dus aux types mosaïque C/D (élevages de poulets de chair et de dindes) suivi de…
Structural brain network fingerprints of focal dystonia
2019
Background: Focal dystonias are severe and disabling movement disorders of a still unclear origin. The structural brain networks associated with focal dystonia have not been well characterized. Here, we investigated structural brain network fingerprints in patients with blepharospasm (BSP) compared with those with hemifacial spasm (HFS), and healthy controls (HC). The patients were also examined following treatment with botulinum neurotoxin (BoNT). Methods: This study included matched groups of 13 BSP patients, 13 HFS patients, and 13 HC. We measured patients using structural-magnetic resonance imaging (MRI) at baseline and after one month BoNT treatment, at time points of maximal and minim…

Abstract Hakkinen A, Ylinen J, Rinta-Keturi M, Talvitie U, Kautiainen H, Rissanen A. Decreased neck muscle strength is highly associated with pain in cervical dystonia patients treated with botulinum toxin injections. Arch Phys Med Rehabil 2004;85:1684–8. Objectives To compare the isometric neck muscle strength of cervical dystonia patients treated with botulinum toxin injections with that of healthy control subjects and to evaluate the association between neck strength, neck pain, and disability in these patients. Design Clinical cross-sectional study. Setting Outpatient rehabilitation and neurology clinics in a Finnish hospital. Participants Twenty-three patients with cervical dystonia wi…
Lateral pterygoid muscle dystonia. A new technique for treatment with botulinum toxin guided by electromyography and arthroscopy
2010
Lateral pterygoid muscle dystonia is characterized by mandibular displacement towards the opposite side of the affected muscle. It may be associated with functional disorders affecting speech, swallowing, chewing and facial symmetry. Injection with botulinum toxin is recognized as the most effective treatment. Locating the lower head of the lateral pterygoid muscle for the injection is not difficult using electromyographic guidance; however, location of the upper head is more complicated, even with electromyography. We report a case of lateral pterygoid muscle dystonia in which precise injection of the upper head was achieved with the aid of arthroscopy.
SNAP-25a and -25b isoforms are both expressed in insulin-secreting cells and can function in insulin secretion
1999
The tSNARE (the target-membrane soluble NSF-attachment protein receptor, where NSF is N-ethylmaleimide-sensitive fusion protein) synaptosomal-associated protein of 25 kDa (SNAP-25) is expressed in pancreatic B-cells and its cleavage by botulinum neurotoxin E (BoNT/E) abolishes stimulated secretion of insulin. In the nervous system, two SNAP-25 isoforms (a and b) have been described that are produced by alternative splicing. Here it is shown, using reverse transcriptase PCR, that messages for both SNAP-25 isoforms are expressed in primary pancreatic B and non-B cells as well as in insulin-secreting cell lines. After transfection, both isoforms can be detected at the plasma membrane as well a…
Botulinum Toxin Injection Plus Topical Diltiazem for Chronic Anal Fissure: A Randomized Double-Blind Clinical Trial and Long-term Outcome.
2021
BACKGROUND: Chemical sphincterotomy avoids the risk of permanent incontinence in the treatment of chronic anal fissure, but it does not reach the efficacy of surgery and recurrence is high. Drug combination has been proposed to overcome these drawbacks.; OBJECTIVE: This study aimed to compare the clinical, morphological, and functional effects of combined therapy with botulinum toxin injection and topical diltiazem in chronic anal fissure and to assess the long-term outcome after healing.; DESIGN: This is a randomized, controlled, double-blind, 2-arm, parallel-group trial with a long-term follow-up.; SETTINGS: This study was conducted at a tertiary care center.; PATIENTS: A total of 70 cons…
Gabapentin in the treatment of hemifacial spasm
2001
Objectives To evaluate the efficacy of gabapentin in the treatment of hemifacial spasm. Material and methods Twenty-three patients with hemifacial spasm not suitable for surgery or therapy with botulinum toxin were treated with gabapentin. The main efficacy parameter was the percentage of spasm reduction. Results A clinically significant reduction of spasms was obtained by 16 patients. Conclusion Gabapentin was effective and safe in reducing hemifacial spasm in 16 out 23 (69.6%) patients.
Altered functional connectivity in blepharospasm/orofacial dystonia
2017
Abstract Introduction Blepharospasm is characterized by involuntary eyelid spasms. It can be associated with perioral dystonia (Meige's syndrome or orofacial dystonia). We aimed at studying resting‐state functional brain connectivity in these patients and its potential modulation by therapeutic botulinum toxin injections. Methods We performed resting‐state functional MRI and a region of interest‐based analysis of functional connectivity in 13 patients with blepharospasm/Meige's syndrome in comparison to 13 healthy controls. Patients were studied before and 4 weeks after botulinum toxin treatment. Simultaneous facial electromyography was applied to control for involuntary facial movements. R…
