To evaluate the long-term effect of botulinum toxin type A (BTX) in the treatment of blepharospasm, a retrospective analysis was conducted from the patients seen at the Movement Disorders Clinic of the Department of Neurology, Hospital das Clínicas, University of São Paulo School of Medicine from 1993 to 2003. A total of 379 treatments with BTX were administered to 30 patients with blepharospasm. Sixty six per cent of the subjects had used oral medication for dystonia and only 15% of them reported satisfactory response to this treatment. Ninety three per cent of the patients showed significant improvement after the first BTX injection. There was no decrement in response when compared the first and the last injection recorded. Adverse effects, mostly minor, developed at least once in 53% of patients. Six patients (20%) discontinued the treatment but there was no case of secondary resistance.

In order to evaluate the long-term effect of botulinum toxin type A (BTX) in the treatment of hemifacial spasm (HFS), a retrospective analysis of patients treated at the Movement Disorders Unit of the Division of Neurology, Clinical Hospital, University of São Paulo, School of Medicine from 1993 to 2004 was made. A total of 808 injections with BTX were administered to 54 patients with HFS. The mean duration of improvement per application was 3.46 months and the mean rate of improvement using subjective judgement by the patient was of 83%. Adverse effects, mostly minor, were observed in 64.8% of patients at least once along the period of follow-up and the most frequent of them was orbicularis oris paralysis (38.8%). There was no decrement in response when compared the first and the last injection recorded.

ABSTRACT Hemifacial spasm (HFS) is a common movement disorder characterized by involuntary tonic or clonic contractions of the muscles innervated by the facial nerve. Objective To evaluate the long-term effect of botulinum toxin type A (BTX-A) in the treatment of HFS. Methods A retrospective analysis of patients treated at the Movement Disorders Outpatient Clinic in the Neurology Service, Hospital de Clínicas, Federal University of Paraná, Curitiba, from 2009 to 2013 was carried out. A total of 550 BTX-A injections were administered to 100 HFS patients. Results Mean duration of improvement following each injection session was 3.1 months, mean latency to detection of improvement was 7.1 days and mean success rate was 94.7%. Patients were evaluated at an interval of 5.8 months after each application. Adverse effects, which were mostly minor, were observed in 37% of the patients at least once during follow-up. The most frequent was ptosis (35.1%). Conclusion Treatment of HFS with BTX-A was effective, sustainable and safe and had minimal, well-tolerated side effects.

Most cases of cervical dystonia (CD) are idiopathic, and focal injections of botulinum toxin A (BoNT/A) are the treatment of choice. The objective of our study was to document the effects of long-term BoNT/A treatment in idiopathic CD patients. Fifty-eight patients with idiopathic CD were recruited from March 2001 to May 2002. Twenty-eight of the subjects were available for reassessment after seven years. During this period, all had received regular treatment with BoNT/A injections. Clinical information about patients and the severity of CD (TWSTRS and VAPS) at baseline assessment (2001-2002) and follow-up (2008-2009) was compared. Significant motor improvement was detected based on TWSTRS scale scores, which were used to analyze clinical severity (19.6±6.6 and 17.7±4.8; p<0.05). There was no improvement in the severity of cervical pain (p=0.43). In conclusion, BoNT/A was a safe and effective long-term therapy for CD.

Botulinum toxin type A (BT-A) is used in the treatment of neuroophthalmologic disorders such as essential blepharospasm and facial hemispasm for more than 20 years. Although the long-term effect of repeated application of the BT-A was confirmed, the BT-A effect on tears production and retention is not clear. In our work we investigated whether applied BT-A in patients with blepharospasm and hemifacial spasm affect tears production. Tears quality was measured with Schirmer’s and tear osmolarity test during neuro-ophthalmologic diseases treatment, which was evaluated before and 14 days after application of BT-A (Botox inj, Allergan, Irvine, USA) into the orbicularis oculi muscle. BT-A doses of 16-18 U with unilateral and 32 to 36 U bilateral applications were used. The mean tear production in Schirmer’s test before BT-A application was 8.38 ± 0.63 mm, and 2 weeks after BT-A application was 7.12 ± 0,6 mm (n = 50). Tear osmolarity was 305.4 ± 9.2 mOsm before BT-A application, and 2 weeks after BT-A application it was 305.2 ± 8,6 mOsm (n = 13). We found significant difference between two groups in tear quantity (p < 0.012), but not quality (p > 0.05). Application of the BT-A reduced the amount of tears measured by Schirmer’s test. These results confirm rational basis of the empirical clinical experience where an artificial tears substitution is recommended for patients with neuro-ophthalmologic disorders treated by BT-A.

The original methodology for retrospective clinical studies on the criteria of “efficiency/safety” and pharmacoeconomics on the criteria of “cost/effectiveness”is proposed. The results of a retrospective study of medical records in 169 patients with cerebral palsy, which showed that the use of drugs botulinum toxin type A is an important integral component in the long-term treatment of children with spastic forms of cerebral palsy. Presents the results of pharmacoeconomic analysis of the treatment of the syndrome of spasticity in cerebral palsy when used in the complex treatment of Dysport, Botox and Xeomin.

A 42-year-old female presented in Neurology Department of Sir Salimullah Medical College with gradually worsening difficulty in talking and eating for the last four months. Examination revealed dystonic tongue, macerated lips due to continuous drooling of saliva and aspirated lungs. She had no history of taking antiparkinsonian, neuroleptics or any other drugs causing dystonia. Chest X-ray revealed aspiration pneumonia corrected later by antibiotics. She was treated with botulinum toxin type-A. Twenty units of toxin was injected in six sites of the tongue. The dystonic tongue became normal by 24 hours. Subsequent 16 weeks follow up showed very good result and the patient now can talk and eat normally. (J Bangladesh Coll Phys Surg 2006; 24: 75-78)

Aim: This is a retrospective report of the efficacy of botulinum toxin-A, Botox® (Allergan), in intractable chronic migraine patients non-responsive to previous pharmacological management and with largely no pain-free time, including those with new onset daily persistent headache. Methods: Thirty-three patients, all with severe Headache Impact Test (HIT)-6 scores at baseline, received 3-monthly injections of Botox® as per Phase III REsearch Evaluating Migraine Prophylaxis Therapy (PRE-EMPT) protocol over a maximum 33-month period. Response criteria were a sustained reduction of HIT-6 scores below 60. Results: Four patients had headache on at least 20 days a month; the remaining patients had daily headache with no pain-free time, including nine patients with new onset persistent migraine. There was a significant reduction in HIT-6 scores following Botox® therapy ( x̅ = −5.45, p = 0.000920). Twenty-one percent of the cohort exhibited a sustained reduction in HIT-6 scores below 60. The number of headache days and pain-free time did not change in five of the six responders, but disability improved. There was no difference between patients with episodic migraine evolving to chronic as opposed to those with chronic migraine from onset. Conclusion: This report suggests that Botox® treatment is efficacious in intractable chronic migraine without pain-free time. The HIT-6 is a reliable and practical parameter to assess disability in this patient group. Use of such validated parameters should be considered with greater weight in future International Classification of Headache Disorders (ICHD) guidelines for controlled clinical trials.
