Antidepressant agents in short bowel syndrome.

Purpose: This study aimed to determine whether short small intestine modifies antidepressant concentrations.

Methods: The Css values and concentration-dose ratios (CDRs) of citalopram or escitalopram, administered orally or intravenously, were determined in patients with short bowel syndrome.

Findings: Eight patients (6 males and 2 females) were included in the study.

Effect of cyamemazine on the steady-state plasma concentrations of risperidone and 9-hydroxyrisperidone: a preliminary retrospective study.

Administration of cyamemazine, an antipsychotic drug with anxiolytic properties, together with other antipsychotic agents is common in patients with schizophrenia. This retrospective study investigated the effects of cyamemazine on the steady-state plasma concentrations of risperidone and 9-hydroxyrisperidone in 47 patients treated with 1 to 12 mg/day of risperidone. Of these 47 patients, 24 were receiving cyamemazine comedication ("cyamemazine" group) and 23 patients were treated with risperidone alone ("control" group).

Development and validation of a high-performance liquid chromatography method using diode array detection for the simultaneous quantification of aripiprazole and dehydro-aripiprazole in human plasma.

A high-performance liquid chromatography method with diode array detection (HPLC-DAD) was developed for quantification of aripiprazole and dehydro-aripiprazole, in human plasma. After a simple liquid-liquid extraction, chromatographic separation was carried out on a C18 reversed-phase column, using an ammonium buffer-acetonitrile mobile phase (40:60, v/v). The total run time was only 7 min at a flow-rate of 1.

Therapeutic drug monitoring of levetiracetam by high-performance liquid chromatography with photodiode array ultraviolet detection: preliminary observations on correlation between plasma concentration and clinical response in patients with refractory epilepsy.

Levetiracetam is a new antiepileptic drug prescribed for the treatment of patients with refractory partial seizures with or without secondary generalization as well as for the treatment of juvenile myoclonic epilepsy. A rapid and specific method by high-performance liquid chromatography diode array detection was developed to measure the concentration of levetiracetam in human plasma. The trough plasma concentrations measured in 69 epileptic patients treated with 500 to 3000 mg/d of levetiracetam ranged from 1.

Association of CK19 mRNA detection of occult cancer cells in mediastinal lymph nodes in non-small cell lung carcinoma and high risk of early recurrence.

This study was designed to screen occult cancer cells by CK19 mRNA detection using reverse transcriptase-polymerase chain reaction (RT-PCR) in mediastinal lymph nodes stations (MLNS) in non-small cell lung carcinoma (NSCLC). In 49 NSCLC patients free of mediastinal adenopathy on computed tomograph, 254 MLNS were evaluated by histopathology, immunohistochemistry (IHC) and RT-PCR. Of 225 non-tumoral MLNS on histopathology, 32 (14.
