The long-term clinical effects of pipotiazine palmitate were tested in 206 men and women who were either not responding well to their previous neuroleptic therapy or who were negligent about pursuing protracted oral drug therapy. Of the 206 patients, 130 were suffering from some form of chronic schizophrenia; the remainder presented with depression, psychoneurotic or behavioural disorders. Pipotiazine palmitate, a long-acting depot neuroleptic, was given as a monthly intramuscular injection for up to 23 months. The average starting dose was 50 mg/injection and the average final dose was 65 mg/injection. These doses were somewhat lower than those usually reported in the literature, however all but a few patients received oral neuroleptics or antidepressants concomitantly. Psychiatric testing using the Brief Psychiatric Rating Scale revealed that significant improvement was achieved over time in all diagnostic groups represented. Individual as well as cumulative scores improved steadily for 6 momths at which time symptomatology was minimal in most patients. Pipotiazine palmitate was well tolerated, and only seven (3.4%) of the 206 patients had to interrupt therapy because of unwanted effects. The most frequent side-effects were extrapyramidal symptoms, particularly tremor and rigidity, yet these effects led to the discontinuation of therapy in only five patients.

In two cases of chronic schizophrenia complicated by diabetes mellitus, the concomitant use of the neuroleptica and oral antidiabetics was attended by the appearance of symptoms simulative of syndrome malin, i.e. hyperpyrexia, tachycardia, blood pressure instability, disturbances of consciousness, muscle rigidity, tremor, dysphagia, salivation and urinary incontinence. In one of these cases, the patient, a 47-year-old man, died 10 days later. In the other case, a 62-year-old woman, almost all the symptoms subsided after 14 days, and oral dyskinesia persisted for only one additional month. In both cases, hypoglycemia due to oral antidiabetics was not seen. In Case 2, a combined regimen of oral antidiabetics and neuroleptica was later resumed. Again, a similar set of symptoms as seen initially were noted, along with an elevation of the serum CPK level. Parenterally administered biperiden proved to be highly effective in the control of the symptoms. The pathogenetic mechanism of these symptoms might possibly be explained as potentiation of the action of the neuroleptica by oral antidiabetics.

The objective of this study was to determine the putative risk factors for the development of tardive dystonia (TDt) in contrast with tardive dyskinesia (TD). Fifteen TDt patients seen in the Movement Disorders Clinic were compared with 2 groups of 15 TD controls each. The first control group was drawn from the Clinic and matched with the TDt cases for severity, using degree of dysfunction as the matching variable. The second control group comprised mild TD cases drawn from a separate study of drug-induced movement disorders in chronic schizophrenia and were matched for age and sex with the TDt cases. A number of demographic, treatment-related, diagnosis-related and historical variables suggested in the literature were examined. Most risk factors for TDt that have been suggested by previous studies were not supported. The first control group was significantly older than the TDt cases. The TDt patients had a more frequent past history of acute drug-induced dystonia and of postural tremor prior to the onset of the mental illness, although only the former reached statistical significance. The results suggested that TDt and TD do not differ in most putative risk factors, although the small sample size increases the likelihood of a type II error. It is inconclusive on the role of young age and male sex as risk factors. TDt cases may, however, be individuals vulnerable to the development of dystonia, with neuroleptics probably bringing out such a vulnerability. This finding needs to be examined in larger studies.

The aim of the current study was to assess the prevalence of tardive movement disorders (TMD) among a group of institutionalized schizophrenic and schizoaffective patients in southern region of Israel. Chronic schizophrenic and schizoaffective inpatients of a psychiatric hospital and its affiliated hostels were screened for the presence of TMD subsyndromes. Twenty percent (107 patients) of 523 patients with schizophrenia and schizoaffective disorder exhibited TMD. Of those with TMD, 36% had only one subsyndrome, whereas 64% had a combination of several TMD subsyndromes. With regard to patients with TMD, the most frequent TMD subsyndrome was tardive tremor (TT). TT appeared more often in males compared to females and at a younger age (44.3+/-8 vs. 54.3+/-11 years, P<0.04). TD appearing in combination with other TMD subsyndromes was significantly more prevalent among females than in males (57% vs. 35%; P<0.02). TMD generally appears in a combined fashion. Further prospective studies from different geographical areas are recommended.
