QI purpose was to evaluate the effects of clozapine on negative symptoms d JChiZOPhrenic patients with prominent negative symptomatology. lMthodl: Fourteen neuroleptic resistant schizophrenic patients with ptlITlInerll negative symptoms were treated for one year with clozaplne. SIX out of them were females and 8 males; mean age was about 32 years with 17 to 49 as range. According to the DSM-IV patients were distributed ~ 1h8 folIoWlng schizophrenia subtypes: 11 undifferentiated and 3 residual. A mean doS8 of c10zaplne was 250 mg daily. All patients were assessed by IlafldaIdized clinical evaluation.

I male sexual functions at masturbation

165-100 The Impact of neuroleptic maintenance therapy on P.B. Kores, B. zalar. University Psychiatric Clinic. StucJenec 48 1260 Ljubljana-Polje, Slovenia ' ~en, who receive neuroleptic therapy often complain about sexual dysfunc• liOns. In this work sexual functions and dysfunctions at masturbation are p~esented bot~ in males who received long tenn neuroleptic treatment either With fluphenazine, haloperidol or zuclopenthlxol depot, and In healthy males. Methods: We assessed sexual functions and dysfunctions at masturbation In the group of 59 patients before and during neuroleptic maintenance treatment and In the group of 25 healthy men. Questioners adjusted for this survey were used, as w~II as MMPlfor assessing the validity of answers. Data have been calculated With parametrical Kruskal-Wallis and/or Mann-Whitney statistical techniques. Results: The frequency of masturbation was higher before the treatment (89"10) and In.l!Je healthy controls (97%). During long term therapy there were more .dlfflcultl.es (p < 0.05) in obtaining erection, there were more orgasms Without ejaculation (p < 0.05), painfUl ejaculations (p < 0.05) and white urine-retrograde ejaculations (p < 0.05) than in the time before maintenance neuroleptic treatment and In control group. Partnership or the lack ~f partnership was without any influence on sexual functions at masturbatlo~. We could not prove the influence either of neuroleptic type or of neuroleptiC dosage on sexual function at masturbation. The presence of sexual dysfunctions is also Influenced by the criticalness of selfassessment In both groups and by the absence of objective methods of assessing sexual functions.

Italy •• • The eff~eness of treatment of psychotic patients with risperidone (RSP) together With psychosocial and psychotherapeutic support has been evalu• ated. Methods: 18 outpatients with average 41.8 ± 12.16 SO affected by Undll• ferentiad Schizophrenia (OSM IV) with a prevalence of negative symptoms a~or behavioural abnonnalities and aggressiveness wene studied. Th~ pa~lents have been treated with RSP at a dosage ranging from 2 to 6 mg dally (mean 4.17 mg ± 1.19 SO) for 9 months. At the and of the study plasma levels of the d~g and Its active metabolite hydroxl-risperidone wer~ perlonned. T~e~her With the phannacologlcal therapy, psychotherapeutic and/or re.h~dltetive tre~tment was administered. Patients were evaluated from a clinical perspective and side effects on the SPRS, PANSS EPSE ACS scales. ' , Results: Patients showed a significant decrease In the scores of the evaluations scales, showing a good tollerance to the drug. The joint ap• proach, phannacotherapy-psych?the~peutic and/or psychosocial support tumed out to be effectIVe, especially In those pathologies characterized by autistic withdrawal and behavioral abnonnallties.
