Evaluation of the interference of lamotrigine on the analysis of synthetic cannabinoids in urine by the immunoassay method.

We aimed to evaluate the interference of lamotrigine (LMG) on the synthetic cannabinoids metabolite-K2/1 (SCm/K1) urine test by Homogeneous Enzyme Immunoassay (Immune-SCm/K1). This study consists of two parts: case-control and interference effect research. In the case-control study, two groups using LMG and a non-use of LMG were formed, all of them non-SC users.

Continuing clozapine treatment with lithium in schizophrenic patients with neutropenia or leukopenia: brief review of literature with case reports.

Objective: Clozapine is a second-generation antipsychotic used for treatment-resistant schizophrenia. Despite its effectiveness, clozapine is largely underused due to serious side effects such as leukopenia or neutropenia. We aimed to review whether to continue, discontinue or rechallenge clozapine treatment after such haematological side effects.

Auditory P300 event-related potential in tobacco smokers.

The aim of this study was to elucidate the chronic effects of tobacco smoking on the P300, a neurophysiological index of cognitive function. Prospective study participants were recruited from a family medicine polyclinic. We selected 32 right-handed smokers who had smoked more than 15 cigarettes per day, by inhalation, for more than 2 years.
