Trihexyphenidyl (Artane) abuse in schizophrenic patients.

Trihexyphenidyl (THP) and other anticholinergics are liable to abuse by schizophrenic patients. Data concerning the incidence and characteristics of the abusers are scarce. In the present study an evaluation of 214 consecutive admissions of schizophrenic patients revealed 14 THP abusers, an incidence of 6.5%. The demographic and clinical variables of the THP abusers were compared with a randomized control group of 28 schizophrenic patients using the four-dimensional factors of the BPRS (Brief Psychiatric Rating Scale). No significant differences were found in demographic variables and comorbidity for antisocial personality disorder and other substances abuse. On admission, a trend towards more negative symptoms was detected among abusers. At discharge abusers had significantly higher mean BPRS scores and higher scores on the dimensional factor of hostile-suspiciousness. The results suggest that THP abuse is not rare among schizophrenic patients who may abuse anticholinergic agents to relieve negative symptoms and/or drug-induced Parkinsonism, or alternatively for its non-specific stimulant effects, on account of worsening of positive symptoms.

Cyproheptadine treatment of sexual dysfunction induced by serotonin reuptake inhibitors.

Treatment of serotonin reuptake inhibitors (SRIs) is associated with sexual dysfunction. The cause of this dysfunction is unclear but may be related to stimulation of the serotonergic system. In the present article, we describe seven patients in whom iatrogenic sexual dysfunction induced by SRIs was treated with cyproheptadine, a 5HT-2 antagonist with antihistaminergic and adrenolytic properties. Seven obsessive-compulsive male patients, aged 29-54 years, who developed sexual dysfunction following treatment with SRIs (fluoxetine, fluvoxamine, and clomipramine) were instructed to take cyproheptadine (4-12 mg) 1-2 h before commencing sexual activity. Five of the seven patients displayed improvement in sexual function, although the improvement was transitory in two. The two remaining patients did not respond. All patients exhibited sedation on the day following cyproheptadine administration. Our preliminary observation suggests that some patients with sexual dysfunction associated with SRI treatment, mainly decreased libido and anorgasmia, may benefit from cyproheptadine administration. The role of 5HT-2 antagonists in SRI-induced sexual dysfunction merits further investigation.

Cyproheptadine treatment in neuroleptic-induced akathisia.

BACKGROUND: Cyproheptadine, an antiserotonergic agent, was used to treat neuroleptic-induced akathisia. METHOD: In an open clinical trial 17 neuroleptic-treated patients with akathisia were administered cyproheptadine (16 mg/day) over 4 days. Assessment of akathisia, psychosis and depression were monitored by BAS, BPRS and HAM-D. RESULTS: All subjects showed improvement in the severity of akathisia, which in the majority (15/17) was of a marked degree. There was no aggravation of psychosis or depression. Symptoms of akathisia returned when cyproheptadine was discontinued. CONCLUSIONS: Cyproheptadine may be useful in neuroleptic-induced akathisia.

Sexual dysfunction in male schizophrenic patients.

BACKGROUND: Neuroleptic treatment in schizophrenic patients is associated with sexual dysfunction. However, it is not clear to what extent the psychiatric disorder and/or the pharmacologic treatment are responsible for the sexual impairment. The aim of the present study was to evaluate the sexual function of untreated and treated male schizophrenic patients in comparison with healthy subjects. METHOD: Participants included 122 male subjects: 20 drug-free schizophrenic patients, 51 neuroleptic-treated (depot form) schizophrenic patients, and 51 normal controls. A detailed structured interview was used to quantitatively and qualitatively assess sexual function. RESULTS: A high frequency of sexual dysfunction was reported by both schizophrenic groups of patients. Impairments in arousal items (erection) and orgasm during sex were reported mainly by the treated patients. Desire parameters were reduced in both schizophrenic groups, but reduction in the frequency of sexual thoughts was confined to the untreated one. The schizophrenic patients were more involved in masturbatory activity in comparison with the control subjects. Treated patients disclosed dissatisfaction with their sexual function. CONCLUSION: Untreated schizophrenic patients exhibit decreased sexual desire. Neuroleptic treatment is associated with restoration of sexual desire yet it entails erectile, orgasmic, and sexual satisfaction problems. Clinicians' awareness and open discussion of sexual problems with patients may improve comprehension and compliance.

Electroconvulsive therapy for persistent neuroleptic-induced akathisia and parkinsonism: a case report.

Neuroleptic-induced akathisia (NIA) and parkinsonism (NIP) continued for 3 months, despite two courses of anticholinergic treatments, a shift to low-potent neuroleptic (NL) and a NL-free period. The two adverse effects responded dramatically to electroconvulsive therapy (ECT) to reemerge 3 months after termination of ECT. The case supports the idea that ECT is effective for both NIA and NIP even when they are resistant.

Risk for definite neuroleptic malignant syndrome. A prospective study in 223 consecutive in-patients.

The occurrence of neuroleptic malignant syndrome (NMS) was studied prospectively in two series of consecutive psychiatric in-patients (n = 223). The first group (n = 120) suffered from schizophrenia and was treated only with haloperidol. The second group (n = 103) was treated with diverse neuroleptics. All patients were on a single antipsychotic agent with no anticholinergic drug as prophylaxis. The incidence of full NMS per admission and first neuroleptic exposure was 5/223 (2.2%). Patients with bipolar affective disorder and those treated with injections were significantly over-represented in the NMS group.

[Withdrawal reactions after clomipramine].

Abrupt or gradual discontinuation of tricyclic antidepressants may precipitate withdrawal symptoms. The most common of these are general somatic or gastrointestinal distress, anxiety and agitation, sleep disturbance, akathisia, parkinsonism, paradoxical behavioral activation and mania. There are very few reports of withdrawal reactions following discontinuation of clomipramine since it has not been in use in the US until recently. 2 patients with withdrawal symptoms following discontinuation of clomipramine are presented. A 45-year-old man had general somatic symptoms, including headache, myalgia, weakness, fatigue (flu-like syndrome) and nervousness and insomnia after clomipramine, 75 mg/d, had been discontinued abruptly. All symptoms disappeared without treatment after 3 days. A 47-year-old woman presented mainly with severe insomnia, anxiety, agitation, jitteriness and tension after discontinuing a low dose of 25 mg/d of clomipramine. Symptoms disappeared after she started self-treatment with 50 mg/d of the drug. It is important to differentiate withdrawal symptoms from relapse of the primary psychiatric disorder.

TRH stimulation test in obsessive-compulsive patients.

Serum thyroid stimulating hormone (TSH), prolactin (PRL), and growth hormone (GH) levels were measured before and after stimulation with 200 micrograms of thyrotropin releasing hormone (TRH) in 10 patients with obsessive-compulsive disorder (OCD) and in 10 control subjects. There were significantly more blunted TSH responses among OCD patients than control subjects. PRL and GH responses to TRH challenge did not differ between OCD patients and controls. These results may indicate dysregulation of the hypothalamic-pituitary-thyroid axis in OCD.

Leukocyte adhesiveness/aggregation and neuroleptic drug treatment.

Leukocyte adhesiveness/aggregation as measured by the leukergy test was studied in peripheral citrated blood of two groups of schizophrenic patients treated with neuroleptic drugs. In the first group (N = 25) leukergy test was performed before and after commencement of neuroleptic treatment to acutely psychotic hospitalized patients. The second group studied (N = 25) were stabilized outpatients receiving long term neuroleptic medications for at least 3 months. There was a significant rise in leukergy rates between the drug free period and the subsequent measurements performed after 1 and 7 days of neuroleptic treatment in the first group (p less than 0.001). Similar high leukergy rates were noted in the second group of remitted patients. High leukergy rates were related to neuroleptic therapy and not to the psychotic state of the patients.

Musical hallucinations and hearing deficit in a young non-psychotic female.

A case of musical hallucinations in a young non-psychotic female is described. The only presented symptoms were perceptual disturbances accompanied by the fear of having a severe mental disorder. Further investigation disclosed a perforated ear-drum, with subsequent mild hearing deficit but no signs of major psychopathology. It is suggested that a psychiatric diagnosis should be deferred in such patients, before audible deficits had been ruled out. The clinical features of musical hallucinations associated with hearing deficits are discussed.

Delusional parasitosis associated with phenelzine.

A woman developed delusional parasitosis when taking phenelzine. The delusion occurred in an agitated hypomanic state and was preceded by an intense pruritus. It completely remitted following withdrawal of phenelzine combined with a low dose of haloperidol (1 mg/day) for several days. This unusual psychopathology is probably encountered more by dermatologists than by mental health professionals.

Painful ejaculation associated with antidepressants in four patients.

BACKGROUND: Painful ejaculation associated with tricyclic antidepressants is rarely reported in the medical literature. METHOD: Painful ejaculation following the administration of imipramine and clomipramine is described in four patients. RESULTS: The phenomenon occurred in all patients during the first 3 weeks of treatment and disappeared within several days when the tricyclic dosage was reduced or the medication was withdrawn. CONCLUSION: Painful ejaculation was apparently evoked by tricyclic antidepressant administration. Clinicians should be aware of this underreported side effect.
