Retrograde ejaculation associated with quetiapine and treatment with low-dose imipramine.

Sexual side-effects are common among those using antipsychotic medication and may result in poor compliance and reduced quality of life. Retrograde ejaculation (RE) has been described occurring with a number of antipsychotic medications (thioridazine, risperidone, iloperidone and clozapine) but there are no guidelines regarding management of antipsychotic-associated RE. Imipramine has been suggested as a treatment for antipsychotic-associated RE in one small study of patients prescribed thioridazine and a case series of patients prescribed iloperidone. Quetiapine is a commonly used antipsychotic and is thought to be associated with less sexual side-effects relative to other antipsychotic medications. This case report describes a 25-year-old man with first episode psychosis who developed RE during treatment with quetiapine which improved with low-dose imipramine. This is the first description of RE occurring with quetiapine and successful treatment of quetiapine-associated RE with imipramine.

A systematic review and critical evaluation of the immunology of chronic fatigue syndrome.

OBJECTIVE: Immune dysfunction in patients with chronic fatigue syndrome (CFS) has been widely but inconsistently reported. Traditional reviews of the literature have produced a variety of conclusions. We present the results of the first systematic review of the subject. METHODS: EMBASE, MEDLINE and PSYCHINFO databases were searched, and leading researchers in the field were contacted. Inclusion criteria were applied, and studies were then divided into groups based on the quality of their methodology. Study results were collated and described. RESULTS: Studies ranged widely in quality. There was an inverse association between study quality and finding low levels of natural killer cells, suggesting that the association may be related to study methodology. On the other hand, reports of abnormalities in T cells and cytokine levels were not related to study quality. CONCLUSIONS: The conclusions of this systematic review differ from a recent traditional narrative review of the immunology of CFS. No consistent pattern of immunological abnormalities is identified.
