Dose-dependent olanzapine-associated leukopenia: three case reports.

Leukopenia and agranulocytosis are well reported and dangerous haematological side-effects associated with the use of typical and atypical antipsychotics. These potentially life-threatening phenomena have led to treatment discontinuation and the consequent reemergence of psychiatric symptoms. We report three cases of patients who developed leukopenia during olanzapine treatment. In each case, the leukopenia was dose-dependent. Reduction in the dose of olanzapine was followed by normalization of the white blood count which allowed continuation of the medication. These cases suggest the possibility that, in some patients, leukopenia or agranulocytosis during olanzapine treatment might be dose-related. Thus, olanzapine dose reduction may permit treatment continuation where this is clinically indicated. In our cases, haematological side-effects were satisfactorily controlled by dose reduction without allowing the reemergence of psychiatric symptoms. This clinical management may offer an alternative to treatment suspension. A careful monitoring of the white blood count is obviously recommended. Olanzapine may be considered a potential and safer treatment for a this specific group of patients.

Intermittent, luteal phase nefazodone treatment of premenstrual dysphoric disorder.

Three outpatients who fulfilled full DSM-IV diagnostic criteria for premenstrual dysphoric disorder (PDD) were successfully treated with intermittent (luteal phase) nefazodone. They received the medication at low doses of up to 100 mg/day (50 mg b.i.d.), for 2 weeks through the luteal phase of the menstrual cycle only. All the patients reported a marked symptomatic improvement, including full remission of their emotional symptoms, and two achieved in addition full remission of their somatic symptoms. Side-effects reported during the treatment were mild. The use of luteal phase nefazodone seems to be a promising treatment strategy for the management of PDD. It offers advantages over daily dosing throughout the menstrual cycle, such as reduced incidence and severity of side-effects, and avoids the stigma that may accompany the continuous use of psychopharmacological treatment, with the advantage that compliance may be improved.

LSD-induced Hallucinogen Persisting Perception Disorder treated with clonazepam: two case reports.

Benzodiazepines are recommended for the treatment of Hallucinogen Persisting Perception Disorder (HPPD), although it is unclear which may be more helpful. Two out-patients with LSD-induced HPPD were successfully treated with clonazepam. They had not responded to low potency benzodiazepines or low doses of classic antipsychotics. After clonazepam discontinuation they reported a marked improvement and only mild symptomatology which persisted during a six month follow-up period. High potency benzodiazepines like clonazepam, which has serotonergic properties, may be superior to low-potency benzodiazepines in the treatment of some patients with LSD-induced HPPD.

LSD-induced hallucinogen persisting perception disorder treatment with clonidine: an open pilot study.

A pilot open study was conducted in order to evaluate the efficacy of clonidine in the treatment of LSD-induced hallucinogen persisting perception disorder (HPPD). Eight patients fulfilled entrance criteria. All complained of HPPD for at least 3 months and were drug free at least 3 months. They received fixed low doses of clonidine, 0.025 mg, three times a day for 2 months. They were evaluated by the Clinical Global Impression Scale (CGI) and a self-report scale on the severity of symptoms (graded 0-5). Patients scored an average of 5.25 (SD = 0.46) on the CGI and 4 on the self-report scale at baseline, indicating marked psychopathology. One patient dropped out at week 3 and a second patient dropped out at week 5. Of the six patients remaining at the end of 2 months, the average CGI score was 2.5 (SD = 0.55) and the self-report scale score was 2, indicating mild symptomatology. LSD-related flashbacks associated with excessive sympathetic nervous activity may be alleviated with clonidine in some patients.

Bouveret's syndrome presenting as upper gastrointestinal hemorrhage.

A unique case of hematemesis is presented. The cause of upper gastrointestinal bleeding was a pyloroduodenal ulcer caused by erosion of a 5-cm gallstone impacted in the duodenal bulb. On review of the world literature of Bouveret's syndrome, this is the first case in which a preoperative diagnosis was well established and the fourth such case in which a successful surgical outcome was obtained.
