Freezing of gait is a symptom of Parkinson's disease (PD) that becomes more evident with the evolution of the disease, and which presents an important difference compared to the other signs and symptoms: does not respond adequately to dopaminergic therapy, which calls into question its pathophysiology. In this sense, and through empirical experience, it has been noted that freezing responds to cueing techniques (visual, sensory motor, auditory tricks, among others) which suggests a similarity with dystonic pathology. This similarity could be the basis of a common response to botulinum toxin (BT). Objectives: This study aims to understand whether BT is an effective therapy for freezing gait in patients with Parkinson's disease. Methodology: This is a prospective parallel study with therapeutic intervention, controlled by placebo, double blind. The randomization of groups will be stratified. The population will be recruited from from the CHLC movement disorders consultation, and that meets the following inclusion criteria: Parkinson's disease with freezing of gait, scoring > 1 at point 2.13 on the scale MDS-UPDRS and be responsive to cueing techniques, with severity of Parkinson's disease rated 3 or 4 on the Hoehn & Yahr scale. The BT injection will be performed by a doctor with experience in this therapy, with 100 Units (U) of type A BT, bilaterally, in the flexor muscle of the thigh, once, with replacement of the same ampoules with saline in controls. To the Patient assessments will take place over 4 months, weekly by telephone using a questionnaires on freezing and the notion of clinical improvement (FOGQ and SCGIC, respectively) and monthly in person with objective assessments using the MDS-UPDRS scales - part III motor assessment, Timed Up & Go and Two Minute Walk.
The patients between the ages of 35-80 who developed spasticity in the upper extremity after stroke will be included.. Botulinum toxin(BT-A) injection will be applied to the study group(n=16) and placebo injection to the control group(n=15) in addition to conventional rehabilitation and stretching exercises. Evaluations will be made before the treatment, in the 2nd week, and in 3rd month after the treatment. Pain relief will be evaluated with the Visual Analog Scale(VAS) and spasticity assessment will be done with the Modified Ashworth Scale(MAS). The functionality will be evaluated with Fugl Meyer Assessment Scale(FMAS) and Box Block Test(BBT).
Research question: Dose the use of oral zinc supplement improve the effects of botulinum toxins injection in patients with myofascial pain dysfunction syndrome? Statement of the problem: MPDS Patients treated with botulinum toxin A injection usually suffers from return of the symptoms which requires successive injections almost every (3-4M) Rationale for conducting the research: The concept of adding the zinc supplementation prior to BTXA injection is contributed to the fact that botulinum toxin is a zinc-dependent metalloprotease; therefore, every botulinum toxin molecule must be accompanied with a zinc molecule to effectively paralyze a muscle. However, commercially available BTXA preparations exclude zinc from their preparations, and BTX clinical efficiency and duration varies according to the zinc levels of the patient. Although the BTX effect could remain for several months, its zinc-dependent proteolytic activity befalls within hours of administration before the toxins are degraded in the tissues. Therefore, for achieving better results from BTX, the recipients should have adequate zinc levels at the time of administration. Therefore, oral zinc supplement intake prior to BTXA injection may enhance its clinical efficiency and duration. botulinum neurotoxins are the most potent toxins known. They bind to nerve cells, penetrate the cytosol and block neurotransmitter release. Comparison of their predicted amino acid sequences reveals a highly conserved segment that contains the HExxH zinc binding motif of metalloendo peptidases. The metal content of tetanus toxin was then measured and it was found that one atom of zinc is bound to the light chain of tetanus toxin. Zinc could be reversibly removed by incubation with heavy metal chelators. Zn2+ is coordinated by two histidines with no involvement in cysteines, suggesting that it plays a catalytic rather than a structural role. Bound Zn + was found to be essential for the tetanus toxin inhibition of neurotransmitter release in Aplysia neurons injected with the light chain. The intracellular activity of the toxin was blocked by phosphoramidon, a very specific inhibitor of zinc endopeptidases. Purified preparations of light chain showed a highly specific proteolytic activity against synaptobrevin, an integral membrane protein of small synaptic vesicles. The present findings indicate that tetanus toxin, and possibly also the botulinum neurotoxins, are metalloproteases and that they block neurotransmitter release via this protease activity. So The use of zinc supplementation prior to BTXA injection has been suggested by several previous studies to prolong its duration of action as well as improve its efficacy
A Phase 2, randomized, double-blind, placebo-controlled repeat dose trial
The aim of this study is to quantitatively record the opinions regarding the pros and cons of this treatment of the caregivers of children with cerebral palsy who had botulinum toxin applied in investigators' clinic.
Botulinum toxin is approved by the FDA for the treatment of facial wrinkles. Patients are usually older than 45 years and their main demand is to treat pre-existing facial wrinkles. However with the increasing popularity of this technique, younger patients, aged 25 to 35 years, are now seeking botulinum toxin injection as a preventive measure for rhytides. The usual dose used for the treatment of facial rhytides in a female patient older than 45 years is 50 units. No consensus exists concerning the dose of botulinum toxin that should be used in younger patients. Hypothesis: lower dose of botulinum toxin is sufficient to give good and long lasting results in young patients. The objective of this randomized open-label study is to evaluate the effect of lower doses of Botulinum toxin on the facial rythides in young patients.
Purpose: The aim of this study was investigate the effects of botulinum toxin type A (BoNT-A) associated with physical therapy on the functional capacity of children with spastic cerebral palsy (CP). Material and methods: Twenty-four children with spastic CP were concealed and randomly assigned to the Experimental Group (EG) consisting of 12 patients treated with BoNT-A and physical therapy and Control with 12 patients treated only with physical therapy. All participants were assessed through motor and functional scales (GMFM-88, Ashworth, Berg Balance Scale, TUG test and Pediatric Evaluation of Disability Inventory) at three different times: before and after 30 days of treatment as well as 3 months after the end of treatment.
We hypothesize that LESWs might temporarily increase urothelial permeability and facilitate delivery of intravesical botulinum toxin without the need for injection.
purpose: The aim of this study is to compare the safety, efficacy and durability of different doses of BTX-A (50 and 100 unit) in the treatment of Vasculogenic Erectile Dysfunction after failure of other ICI therapy. Patients and Methods: This study will be conducted on 200 patients diagnosed as vascular erectile dysfunction by penile color Doppler not responding to medical and injection therapy presenting to Urology department and outpatient clinic at Benha University Hospital, Andrology, Sexology & STD's outpatient clinic, Kasr El Aini Hospitals, Cairo University.(multicentric study). A- Inclusion criteria: - Age between 40 to 70 years. - Vascular ED proved by penile duplex. - Unable to develop erections sufficient for intercourse. - A "No" response on Sexual encounter profile questions (SEP 2 & 3) - Failing to respond to first line and second line treatments for Erectile Dysfunction with surgery as the only remaining treatment option. B-Exclusion criteria: - Significant cardiovascular disease interfering with sexual activity - Any history of an unstable medical or psychiatric condition - Any presence of penile anatomical abnormalities (e.g. penile fibrosis) that would significantly impair erectile function. patients will be simply randomized into 3 equal groups, one control group and two treatment groups. Ethics committee approval and informed consent were obtained.
