Forty-eight patients were given serial injections of botulinum toxin in their eyelids for treatment of eyelid spasm during a two-year interval. Ninety-four percent obtained relief of spasm from botulinum toxin injection. The duration of the spasm-free interval as well as the incidence of ptosis and of diplopia was dose dependent. The marked increase in the incidence of these side effects with only a small increase in the duration of the spasm-free interval, when a dose of 25 units per lid was used, leads the authors to conclude that this dose is too high and should not be used. Since diplopia was most commonly caused by paresis of the inferior oblique muscle, and since blepharospasm usually can be controlled by excising the upper lid protractors, further studies are required to determine whether lower lid injection is necessary and, if it is found to be so, whether injecting only the lateral portion of the lid would be adequate.

Twenty-six patients with essential blepharospasm were treated with botulinum toxin by injection. The onset of protractor weakness in all patients ranged from one to five days following treatment. Maximal weakness developed within 12 days. There was a variable and gradual return of protractor strength over eight to 29 weeks in most patients and, with it, a return of spasm. Twenty-five patients received some degree of functional relief following initial injection. In most patients, however, the post-injection result could not be stabilized and repeat injections have been necessary to control recurrent spasms. There was one treatment failure. Three patients treated by injection following previous neurectomy and myectomy appeared to have a reduced requirement for subsequent injections. Complications included transient ptosis in six patients and mild exposure symptoms in four patients. Extraocular muscle paresis did not occur. There were no systemic side effects from the botulinum toxin injections.

Purified botulinum A exotoxin was used in the treatment of forty seven patients with benign essential blepharospasm, 11 patients with hemifacial spasm and 2 patients with age-related entropion. The treatment was effective in all three groups for an average of 3-4 months when symptoms recurred and repeated chemodenervation with toxin was needed. The commonest complication was transient ptosis with an overall frequency of 7.8%. This incidence increased to 11.1% with toxin doses higher than 25 units per orbicularis. The treatment was well accepted by the patients, who were subsequently able to return to pre-blepharospasm lifestyles.

Twenty-eight patients with mild or moderate cases of benign essential blepharospasm were treated with botulinum toxin Type A. Average follow-up was six months. The injection technique used on these patients is illustrated. The treatment was effective in virtually all patients treated, although transient; the mean interval of relief of spasm was approximately two and one-half months. Potential side effects include ptosis and epiphora. Botulinum toxin as an initial treatment or as an adjunct in postsurgical residual blepharospasm shows promise in this preliminary study.

The authors report 2 cases of myocardial infarction with normal coronary arteries occurring at an interval of 2 months in 2 brothers aged 32 and 34. Following an episode of angina, the younger brother, a sportsman, but a smoker, developed an antero-septal infarct at rest, which was complicated by complete persistent right bundle branch block. Ventriculography and coronary angiography were normal. Induced spasm tests were not performed. The elder brother presented an infero-apico-lateral infarct on effort, without any prodromal syndrome, which was complicated by apical akinesia. Ventriculography revealed mitral prolapse. Coronary angiography was normal and the methylergometrine test was negative. In relation to this example of familial infarction with normal coronary vessels, the authors review the features of this type of infarction reported in the literature which predominantly occurs in young people. They discuss the principal points of interest, including the incidence, the criteria of definition based on the coronary angiography, the elements of the prognosis, the pathophysiological mechanisms and the possibility of a genetic predisposition.

Purified botulinum A exotoxin was used to treat 9 adults with strabismus, 22 adults with incapacitating essential blepharospasm and 1 adult with "senile" spastic lower-eyelid entropion. Eight of the strabismus patients received one injection each into one horizontal extraocular muscle under electromyographic control in the outpatient clinic; the ninth patient received two injections. One week after the injection there was an 81% change on average in the angle of deviation. In the three patients followed up for 4 to 9 months the average change was 66%. For the patients with blepharospasm the toxin was injected into the orbicularis oculi. Relief of spasm lasted an average of 12 weeks after the first treatment and 15 weeks after the second. In the patient with spastic entropion the symptoms resolved with repeated injection of the lower-lid orbicularis. In all three groups the injections were well tolerated. The main complication was transient ptosis, which occurred in about 30% of the first two groups.

The auditory brain-stem response (ABR) can detect anomalies both in the auditory pathways and in structures adjacent to these pathways. Patients with Duane's retraction syndrome, associated with hypoplasia of the abducens nerve in the brain-stem, and patients with hemifacial spasm, due to compression of the facial nerve in the brain-stem, have been found to have abnormal ABRs. Marcus Gunn ptosis with 'jaw winking' is considered to be due to misconnection of oculomotor, trigeminal and other cranial nerves. Suspecting that perhaps some 'jaw-winking' phenomena may be due to detectable brain-stem anomalies we tested 7 patients with Marcus Gunn ptosis. Three of the patients demonstrated abnormal ABRs indicative of pontine pathology.

A 17 year old high school boy experienced fever and diarrhea, which subsided within 4 days by appropriate medications. Six days later, however, he developed unsteadiness and limb spasm. On the morning of admission, he was found to have drowsiness, dysarthria, gait disturbance and involuntary jerks. When he was brought to the hospital, he was lethargic but could follow simple verbal commands. Frequent involuntary movements manifested by facial grimacings, limb spasms and twitchings with dystonic features were seen. Decorticate posturing was readily elicited by painful stimuli. There was no meningeal irritation sign or gross sensory impairment. The deep tendon reflexes were symmetrically exaggerated with bilateral Babinski signs. Bilateral lateral rectus muscle weakness was found together with mild ptosis and upward gaze limitation. Nystagmus was not present and the funduscopic examination was normal. Immediately he was placed on anticonvulsants, steroid hormone, gamma-globulin and antibiotics as well. A brain CT scan and a CSF examination revealed no abnormality. Meanwhile he continued to show a progressive deterioration associated with fever and status epilepticus, and within 24 hours he lapsed into coma in decorticate posture. An EEG obtained at the 3rd hospital day was compatible with spindle coma. In spite of aggressive treatment he remained febrile and comatous. Therefore, vidarabine (adenine arabinoside) was initiated from the 3rd hospital day for 5 days. Then he began to groan and show frequent choreic movements. For the subsequent 2 weeks he made a slow recovery.(ABSTRACT TRUNCATED AT 250 WORDS)

Following several years of experience with a newly designed spectacle-supported ptosis crutch for ptosis and blepharospasm, the author has developed a new approach to these conditions. In mild to moderate blepharospasm cases, the spectacle-supported prosthesis can still produce satisfactory results. However, in moderate to severe blepharospasm, the force of the spasm moves the entire device forward and downward, making it ineffective or too uncomfortable to wear. To create greater stability and a more effective counterforce to the blepharospasm, the author has developed a simple headband-supported device which does not use a spectacle frame for support. This new prosthesis is constructed of varying diameters of spring tempered diamond drawn stainless steel orthodontic wire, partially or completely covered by Teflon tubing. A silicon rubber cylinder is placed over the center which becomes a bridge and the main support for the device. An elastic head band completes the prosthesis.

A prospective open study of botulinum toxin A treatment for patients with various movement disorders at Siriraj Hospital, Mahidol University was analysed to evaluate its efficacy. The grand total of 900 patients comprised of a) 592 patients (65.78 per cent) with hemifacial spasm; b) 92 patients (10.22 per cent) with occupational cramp; c) 79 patients (8.78 per cent) with blepharospasm and Meige syndrome; d) 72 patients (8.00 per cent) with spasmodic torticollis; e) 19 patients (2.11 per cent) with hemidystonia and generalised dystonia; f) 11 patients (1.22 per cent) with spasmodic dysphonia; g) 10 patients (1.11 per cent) with spastic hemiparesis; and h) 25 patients (2.78 per cent) with miscellaneous group (i.e. tics, Gilles de la Tourette, facial myokimia, benign fasciculation, etc.). The results of treatment for hemifacial spasm were classified as excellent in 486 patients (82.09 per cent), moderate improvement in 60 patients (10.14 per cent), mild improvement in 39 patients (6.59 per cent) and no improvement or worse in 7 patients (1.18 per cent). There were complications of mild transient facial weakness in 50 patients (8.45 per cent) and mild ptosis in 12 patients (2.02 per cent). The effect of botulinum toxin treatment lasted 3-6 months. In occupational cramp and spasmodic torticollis the good response rate was around two-thirds of all patients, whereas, blephalospasm, spasmodic dysphonia, spastic hemiparesis and tics responsed in 79-88 per cent of the patients. Botulinum toxin A injection is thus a simple, safe, and effective out-patient treatment for patients with various kinds of movement disorders but it is a costly therapy.
