Torsion dystonia in Israel.

A country-wide search for idiopathic torsion dystonia (ITD) in Israel between 1969 and 1975 revealed 42 patients (41 Jewish and 1 Druze Arab). Prevalence of ITD per million population, age-adjusted to the United States population in 1970, was 10.8 in the total Jewish population (22.0 among Jews of European extraction contrasted with 1.5 among Jews with Afro-Asian forebears). Among Europeans, the highest prevalence was among Jews from Eastern Europe. The average age-adjusted annual incidence rates per million population were 0.43 in the total Jewish population, 0.98 in the Europeans, and 0.11 in the Afro-Asians. Among the 40 patients for whom familial data were available, the majority of cases (26) were sporadic. The other 14 belonged to four unrelated European families, all of Russian-Polish origin. The pattern of inheritance in these four families fits an autosomal dominant model with incomplete penetrance.

Serum dopamine beta hydroxylase activity and metoclopramide provocative test in torsion dystonia.

A familial study of 13 Ashkenasy Jewish patients suffering from torsion dystonia (TD) of various origin, was carried out using clinical observation and determination of serum dopamine-beta-hydroxylase (DBH) activity. None of the following criteria: Jewish origin, dominant trait, slow progression and axial topography are specific for an elevated serum DBH activity. A significantly high serum DBH activity was found in TD patients and their relatives compared with controls, particularly in the childhood onset group. Intravenous injection of 20 mg Metoclopramide (MP) did not change serum DBH activity in 12 patients and 17 relatives. In one patient with symptomatic dystonia and two of her maternal relatives (from different fathers) serum DBH activity increased after i.v. injection of MP. In these three cases the serum DBH activity doubled and tripled. It is suggested that the MP induced elevation of serum DBH activity in relatives of TD patients indicates a genetic disposition.

L-dopa and the secretion of sebum in Parkinsonian patients.

Sebum secretion was studied in 14 parkinsonian patients before and after 3 months of treatment with L-dopa. An abnormality of sebum secretion was shown to exist in parkinsonism. In 7 patients, successfully treated with L-dopa, sebum secretion diminished and its pattern improved. In all patients, in whom L-dopa treatment did not result in noticeable clinical changes, there was no significant modification in sebum secretion. No change was observed in the secretion of sebum of 5 normal control subjects, who were given L-dopa for 1 week.

Skeletal findings in human neutrolethyrism. Is there a human osteolathyrism?

In a review of the roentgenological files of 22 patients suffering from spastic paraplegia due to neurolathyrism, 3 patients were found to present abnormal skeletal findings. 2 patients showed absence of union of the secondary ossification centres of the iliac crests, the ischial tuberosities and the vertebral bodies. Their age at the time of ingestion of poisonous Lathyrus sativus plants was 19 and 20 years. The 3rd patient had bowing and thickening of his right femoral shaft. He was 22 years old at the time of poisoning. These findings which are similar to those found in experimental osteolathyrism have never been described in clinical neurolathyrism. They are of a nature to throw some doubt on the correctness of the currently prevailing concept of sharp distinction between these two pathological entities.

Plasma dopamine beta hydroxylase (D.B.H.) activity in Parkinsonian patients under L-dopa, and 2-bromo-alpha-ergocriptine loading.

Dopamine-Beta-Hydroxylase (D.B.H.)-activity was measured in the plasma of untreated Parkinsonian patients, after tretment with L-dopa and 2-Bromo-alpha-ergocriptine. The findings were compared to the D.B.H.-activity of a matched healthy control group. After L-dopa loading D.B.H.-activity decreased in the Parkinsonian patients by 27.6 +/- 3.1% compared to 16.2 +/- 3.3% (p less than 0.02) in the control group. After 2-Bromo-alpha-ergocriptine laoding the decrease in D.B.H.-activity was 32.6 +/- 4.4% in the parkinsonian patients, and 158 +/- 4.9% (p less than 0.02) in the control group. This reduced D.H.B.-activity after L-dopa loading may reflect an impairment, in the Parkinsonian patients' ability to metaoblize L-dopa. The reduced D.B.H.-activity after treatment with 2-Bromo-alpha-ergocriptine may be explained by a pronounced antagonistic influence of 2-Bromo-alpha-ergocriptine on the presynaptic dopamine receptors, suggesting that presynaptic dopaminergic receptors are involved in Parkinson's disease.

EEG sleep patterns in Parkinsonian patients treated with bromocryptine and L-dopa: a comparative study.

The nocturnal sleep patterns of six Parkinsonian patients treated with Bromocryptine (2-Br-L-ergocryptine CB-154), a dopamine-like agonist, were compared with those of the same patients under L-DOPA treatment. No significant differences were found between the two groups. It is suggested that Bromocryptine, acting on dopamine receptors in the sleep regulating systems at the reticular level in the midbrain has the same effect on sleep patterns of Parkinsonian patients as L-DOPA.

Detrusor hyperreflexia in multiple sclerosis. Alleviation by a combination of imipramine and propantheline, a clinico-laboratory study.

16 patients with multiple sclerosis, complaining of urgency, frequency and urge incontinence were studied urologically. They all suffered from detrusor hyperreflexia. We managed to improve this disturbance by lowering the parasympathetic tone and at the same time increasing the sympathetic tone of the urinary outlet, using a combination of imipramine and propantheline. The subjective clinical alleviation was also corroborated by cystomanometry and urethral pressure profile before and after treatment.

Painful ophthalmoplegia: the Tolosa-Hunt syndrome.

Painful ophthalmoplegia is characterized by unilateral involvement of the IIIrd, IVth and VIth cranial nerves, as well as supra- and retro-orbital pain, i.e. participation of the Vth cranial nerve. The pain is relieved within 48-72 h with steroid therapy. The paresis of the eye muscles in various combinations usually subsides gradually from within a few weeks to several months. The etiology is unknown. The few pathological examinations reported in the literature showed an unspecific inflammatory granulation tissue around the intracavernous portion of the carotid artery and on the dura mater in the vicinity of the cavernous sinus. Carotid arteriography may show stationary waves of this artery and narrowing of its intracavernous portion. With orbital phlebography the occlusion of the supraorbital vein and obstruction of the cavernous sinus are sometimes demonstrable. The syndrome is well defined and its etiology still unknown.

Clomipramine and amitriptyline in the treatment of severe pain.

Clomipramine is the most potent 5-HT reuptake blockade agent among the antidepressants. A comparison between the effect of clomipramine and a less powerful 5-HT reuptake blockade agent (amitriptyline) could test the hypothesis that brain 5-HT is a mediator of pain sensation. Groups of patients of either sex, with pain indication of trigeminal neuralgia, tension headache or postherpatic neuralgia, received doses of clomipramine or amitriptyline in a single blind clinical experiment. The results after three months of treatment showed that clomipramine: (1) was better than amitriptyline in treating trigeminal neuralgia; (2) tended to be better in the treatment of tension headache; and (3) amitriptyline is better in treating postherpatic neuralgia. Clomipramine was better tolerated. The results support the hypothesis that in certain pain situations, clomipramine exerts a beneficial effect, not only because of its effect on the depression and anxiety level of the patient, but also via its effects on the 5-HT brain system.

Myoclonic attacks induced by L-dopa and bromocryptin in Parkinson patients: a sleep EEG study.

Six patients with Parkinson's disease developed nocturnal myoclonic attacks after prolongued treatment with L-Dopa which were electroencephalographically recorded. These symptoms persisted after treatment with 2 bromo-alpha-ergocryptin (Bromocryptin), a dopamine receptor agonist, which was substituted for L-Dopa. Bromocryptin is known to have no pre- or postsynaptic effect on serotonin metabolism. It is proposed that these myoclonic phenomena are the expression of the hypersensitivity of denervated catecholamine receptors in the brainstem to the stimulation of L-Dopa and Bromocryptin. This thesis differs with previous suggestions that serotonin plays a major role in the genesis of myoclonic seizures in Parkinsonian patients treated with L-Dopa.
