Twenty-five patients with various forms of dyskinesia were given tiapride for three months. Maximal dosage was 900 mg per day. A double-blind trial of tiapride versus placebo showed significantly better results in the group given tiapride. The forms of dyskinesia which responded best to tiapride were the following: iatrogenic dyskinesia, tics (Gilles de la Tourette syndrome), and chronic chorea (Huntington disease). Patients with complex dyskinesia resulting from neonatal encephalopathy or vascular disease were not improved. The protocol used in l-dopa-induced dyskinesia is described. Changes in dyskinesia and "on-off" effect following variations in tiapride and l-dopa dosage are detailed. An unequivocal, although minor, tiapride-induced parkinson syndrome was recorded in a few patients. No instances of tiapride-induced dyskinesia or akathisia were seen. The other side-effects were either psychic (depression, drowsiness, agitation) or endocrinologic (menstrual disorders, overeating, galactorrhea).

We report a new syndrome that we call "recurrent optic neuromyelitis with endocrinopathies" in eight Antillean women from Martinique and Guadeloupe Ocular involvement was either monocular or binocular, whereas myelopathy was acute or subacute. In seven patients, myelopathic symptoms recurred, and in six patients, visual problems recurred. Spinal cord involvement was a consistent band-like pseudo-syringomyelic dissociated sensory loss. All eight patients had endocrinopathies consisting of amenorrhea, galactorrhea, diabetes insipidus, hypothyroidism, or hyperphagia. Spinal cord MRI revealed cavitation-like images. Various immunosuppressant treatments had little effect on the uniformly deteriorating course, ending in blindness and paraplegia. Six patients died within 5 years of onset, and an autopsy in one patient showed multiple demyelinizing lesions of the spinal cord with thickened blood vessels walls without evidence of inflammation. These cases appear to constitute a syndrome distinct from MS and from classic Devic's syndrome, not only because of the association with endocrinopathies but because of the stereotypy of the recurrences, the absence of MRI lesions in the cerebral white matter, and the unusual image of cavitation of the spinal cord. The syndrome is also distinct from HTLV-I-associated paraparesis, which is endemic in the West Indies.

More than thirty types of tumors in the sellar region can mimic pituitary adenoma on, magnetic resonance imaging. When they exist, clinical manifestations are not necessarily highly contributive to diagnosis. Headache, visual impairment, signs of antepituitary insufficiency or possible dysmenorrhea with galactorrhea attributed to hyperprolactinemia due to compression of the dopaminergic axis are not specific and may be misleading. Clinical signs of diabetes insipidis and polyphagia are however suggestive of non-pituitary tumors. Consequently, high-resolution imaging (MRI) and sometimes particular diagnostic circumstances (post partum for hypophysitis for example, or breast cancer for metastasis) orient the diagnosis. More rarely tumor enlargement, for example in certain germ cell tumors, provides a clue.

A 15-year-old Hispanic female was started on risperidone for new-onset psychosis. The patient responded well to the gradual dose increase but developed rapid weight gain secondary to polydipsia and polyphagia. She also began complaining of nipple discharge and griping abdominal pain on the left lower quadrant by the third week of treatment. Her prolactin level escalated to three times normal with a weight gain of 12 pounds in 16 days. Risperidone was switched to another antipsychotic. Her prolactin level then dropped to a normal level within 7 days and she lost 7 pounds in the next 2 weeks. Her abdominal pain, galactorrhea, polydipsia, and polyphagia subsided within the first few days of the cessation of risperdione.
