Sensory trick with metoclopramide-associated tardive tremor.

Tardive tremor is a 3-5 Hz bilateral resting and action tremor, associated with the use of dopamine receptor blocking drugs, accompanied by other tardive movement disorders and responsive to tetrabenazine or clozapine. We describe a case of a sensory trick associated with tardive tremor which raises important points about semiology and management. First, the presence of a sensory trick with tardive limb tremor suggests that the disorder may be a form of dystonia. Second, further study of osteopathic manipulative therapy for treatment of dystonia or tardive tremor is supported by a symptomatic response observed in our case.

Prospective, randomized, double-blind study, comparing botulinum toxins type a botox and prosigne for blepharospasm and hemifacial spasm treatment.

Botulinum toxin A (BTA) is considered an effective treatment of blepharospasm and hemifacial spasm, but there are few studies to permit a comparison of its different formulations. This prospective, randomized, double-blind study compared Prosigne, a BTA of Chinese origin, with Botox to establish safety, efficacy, and equivalence of doses between those 2 formulations in blepharospasm and hemifacial spasm treatment. Fifty-seven patients participated in this study: 21 blepharospasm (from whom 11 were treated with Botox; and 10, with Prosigne) and 36 hemifacial spasm patients (17 were treated with Botox; and 19, with Prosigne). All patients were similar in age, disease time span, number of previous shots, and time elapsed since the last BTA application. Pain and burning during the injection and the result of the treatment were similar in both groups. There were no systemic adverse events, and the local ones were observed with similar intensity and frequency for both groups. The mean effect time length was similar for both blepharospasm (11.3 weeks for both toxins) and hemifacial spasm patients (12.8 weeks for Botox and 12.9 weeks for Prosigne). In both blepharospasm groups, only the 36-Item Short-Form Health Survey emotional aspects domain showed improvement from baseline after 16 weeks. There were no differences between the 36-Item Short-Form Health Survey scores before and after the treatment of all hemifacial spasm patients. Therefore, it has been concluded that Botox and Prosigne have similar efficacy, safety, and tolerability profiles, so that a dose equivalence of 1:1 may be considered for blepharospasm and hemifacial spasm treatments.

Avaliação do filme lacrimal de pacientes com distonia facial durante tratamento com toxina botulínica tipo A / Lacrimal film evaluation of patients with facial dystonia during botulinum toxin type A treatment

OBJETIVO: Determinar o efeito da toxina botulínica no filme lacrimal em pacientes com distonia facial. MÉTODOS: Foram incluídos 24 pacientes portadores de blefaroespasmo essencial e espasmo hemifacial que receberam aplicação de toxina botulínica tipo A que foram submetidos à propedêutica do filme lacrimal previamente à aplicação e após, com 7 e 30 dias. RESULTADOS: Houve diminuição das queixas de olho seco trinta dias após a aplicação, entretanto, o tempo de ruptura do filme lacrimal e o teste de Schirmer não demonstraram variação significativa entre os períodos pré-tratamento e 1 mês da aplicação. Em relação ao teste de coloração com rosa bengala, todos os olhos que coraram no pré-tratamento, melhoraram na última avaliação. CONCLUSÃO: A injeção de toxina botulínica pode aliviar as queixas de olho seco nos pacientes com distonia facial pela provável ação de inibição do orbicular na sua função de bomba lacrimal.

Is acupuncture an useful tool for pain-treatment in ophthalmology?

Pain that does not respond to conventional treatment procedures makes it necessary to look for alternative methods. Acupuncture is an ancient procedure with empirical effects on pain. Previous studies established the increased output of messengers at neuronal junctions in spinal cord and hypothalamic locations, especially of endorphins which inhibit the perception of pain. We treated several painful symptoms with acupuncture and evaluated the outcome of the treatment. Patients with various kinds of therapy-refractory pain and patients in whom conventional treatment methods could not be applied were included in the study. The diagnoses included glaucoma. Tolosa-Hunt-Syndrome, ophthalmic migraine, blepharospasm, and dry eyes. In one case acupuncture was used for analgesia during surgery. Acupuncture was performed with sterile disposable needles, at points known to have an empirical analgesic effect. The stimulation was adapted to the patient's individual needs. VAS assessments before and after acupuncture were compared. The t-test was used for statistical evaluation. Acupuncture had no side effects, but reduced pain to a variable extent. Especially in cases of severe pain and in surgery, very effective pain reduction was achieved. In general, pain was significantly reduced in all patients by the use of acupuncture. A statistically significant effect was noted (p < 0.05). Further studies should be conducted to demonstrate the specific effect in larger patient populations. Monitoring neurotransmitter activity will possibly help to illustrate the effect.

[Blepharospasm and Meige's syndrome--a contribution to it's pathogenesis]. / Kurcz powiek i zespól Meige'a--przyczynek do patogenezy.

Two cases with blepharospasm followed by Meige syndrome were described. In the first magnetic resonants revealed bilateral hypodensive foci in thalamus. During the few years general dystonia has been developed after several relapses of disease diagnosed as multiple infarcts followed by aphasia, hemiparesis and asynergia. In the other one, who died, loss of neurons in striatum, especially in caudate nuclei was found. It is concluded that blepharospasm could be a syndrome of different origin and only the phase of Meige syndrome.
