[Dystonias: clinical and therapeutic aspects in 64 patients].

The experience with 64 patients with dystonia seen at the Extrapyramidal Diseases Sector of the Neurology Department of the Hospital Universitário Clementino Fraga Filho of the UFRJ is presented as well as the pertinent review of the literature. The five-and-a-half-year of follow-up showed that 33 were male and 31 female; 48 were white, 10 mulatto and 6 negro; the mean time of disease was 9 years and 8 months. According to the distribution of the movement disorder, 30 (46.9%) were focal, 17 (26.6%) segmental, 13 (20.3%) generalized, 3 (4.7%) hemidystonia and 1 (1.5%) multifocal. In 11 (17.2%) the age of onset was before 12 years old, in 6 (9.4%) between 13 and 20 years old, and in 47 (73.4%) after 20 years old. According to the etiology, 39 (60.9%) were idiopathic sporadic, 6 (9.4%) were idiopathic familial and 19 (29.7%) were symptomatic. The therapeutical approach used in these patients were anticholinergic drugs, dopaminergic agonists or antagonists and baclofen, alone or associated with anticholinergic drugs for generalized dystonia. The authors conclude that botulinum toxin type A is the most valuable therapeutic agent in the treatment of focal dystonia.

[Botulinum toxin in blepharospasm, in hemifacial spasm, and in cervical dystonia: results in 33 patients].

The effects of botulinum toxin type A were studied in 33 patients with dystonia (12 blepharospasms, 10 hemifacial spasms and 11 spasmodic torticollis). A rate scale was used to evaluate the severity of the dystonic movements, before and two weeks after each injection. Among blepharospasm patients, eight were female and four were male; the mean age was 57.7 years; the mean time of the disease duration was four years. Three had familial history for similar disease; nine were essential and three had used neuroleptic drugs (tardive dystonia). The mean dose used was 51.3 U, with a mean time of beneficial effects of 2.8 months. For 22 injections and reinjections, 14 (63.7%) showed an excellent result, five (22.7%) good and three (13.6%) null. In the hemifacial spasm group, eight were female and two male; the mean age was 52.6 years; the mean time of the disease duration was 7.4 years; eight were essential and two post-paralytic. The mean dose used was 32 U. From the total of 15 injections and reinjections, all of them (100%) had an excellent result, with a mean time of beneficial effect of 3.4 months. Among the cervical dystonic patients, eight were male and three female; the mean age was 44.2 years; the mean time of the disease duration was 12.2 years; six had essential dystonia, three had used neuroleptic drugs and two had familial history for similar disease. The mean dose used was 238.6 U, with the mean duration of effect of 3.5 months. From the total of 20 injections and reinjections, 18 (90%) had good result, one (5%) mild and one (5%) null.(ABSTRACT TRUNCATED AT 250 WORDS)

Diffuse encephalic calcification. A case report.

The basal ganglia calcification is known since the last century but with the new neuroimage techniques (CT scan) its diagnosis became more frequent specially in asymptomatic patients. The authors report a case with non-familial primary diffuse encephalic calcification with exuberant calcifications on cerebral hemispheres, cerebellum and brain stem, seen on CT scan.

Segmental myoclonus and basilar artery. Giant aneurysm. Case report.

A 70 years-old man was admitted at our hospital because of unstable angina pectoris. He had essential hypertension and right hemiplegia from a ischemic stroke two years before admission. On neurologic examination, it was found mental disorientation, unstable emotionality, right spastic hemiparesis with right Babinski sign, and segmental myoclonus affecting the superior lip and the palate (palatal nystagmus) on the right side. On the CT scan, a giant aneurysm of the basilar artery was detected. We conclude that the segmental myoclonus could be explained by ischemic lesions in the Guillain-Mollaret triangle.
