Background: Recent studies show that high-dose methadone (>100 mg/d) allow a better control of the consumptions of illicit opiates by treated patients.

Objective: The aim of this retrospective study was to analyze data of patients requiring high-dose methadone (>100 mg/d) as well as associated factors.

Methods: We retrospectively reviewed charts of treated patients with high-dose methadone followed in the maintenance methadone treatment center between 01/01/07 and 01/07/10.

We report the case of a patient with chronic abuse of gamma-butyrolactone (GBL, 3 bottles per week for 4 months), who in the course of the management of acute agitation and hallucinations developed symptoms compatible with both neuroleptic malignant syndrome and GBL withdrawal symptoms.Some GHB withdrawal symptoms are similar to those of neuroleptic malignant syndrome, and the administration of antipsychotics might worsen the neurological condition of patients. So, it seems important to rapidly detect drugs taken by patients with mental agitation, to optimize management and minimize complications related to drugs.

Purpose: First- and second-generation antipsychotics commonly cause mild gastrointestinal hypomotility. Intestinal necrosis may be a consequence of such gastrointestinal perturbations.

Material And Methods: We reviewed all the observations of ischaemic colitis and gastrointestinal necrosis notified to the French Pharmacovigilance database (FPD) between 1997 and the end of 2006.

Objective: To report 2 cases of acute hepatitis related to intravenous administration of buprenorphine in hepatitis C-infected patients.

Case Summary: Two patients, aged 33 and 50 years, respectively, who were hepatitis C virus (HCV) carriers were treated with sublingual buprenorphine 8 mg/day for addiction. Several years after initiation of buprenorphine, they were hospitalized because of clinical hepatitis with jaundice that developed after intravenous injection of buprenorphine.

Objective: To report a case of neurotoxicity related to antiviral drugs, discuss the involvement of concomitant medications, and document the pharmacokinetics of ganciclovir (administered as valganciclovir) in a child with impaired renal function.

Case Summary: A 13-year-old boy with acute lymphoblastic leukemia was treated for cytomegalovirus retinitis with valganciclovir 450 mg every 2 days in the course of hematopoietic stem cell transplantation. Concomitant medication included omeprazole, furosemide, and acetaminophen.

Carbamazepine (CBZ) and oxcarbazepine (OXCBZ) are both antiepileptic drugs, which are prescribed as first-line drugs for the treatment of partial and generalized tonic-clonic epileptic seizures. In this paper, a specific and sensitive liquid chromatography-electrospray ionization mass spectrometry method was described for the simultaneous determination of carbamazepine (CBZ), oxcarbazepine (OXCBZ) and eight of their metabolites [CBZ-10,11-epoxide (CBZ-EP), 10,11-dihydro-10,11-trans-dihydroxy-carbamazepine (DiOH-CBZ), 10-hydroxy-10,11-dihydroCBZ (10-OH-CBZ), 2-hydroxycarbamazepine (2-OH-CBZ), 3-hydroxycarbamazepine (3-OH-CBZ), iminostilbene (IM), acridone (AO) and acridine (AI)] in human plasma. The work-up procedure involved a simple precipitation with acetone.

Background: A firm diagnosis of drug hypersensitivity, because it may re-induce the reaction, is seldom confirmed. Causality assessment algorithms are therefore of interest.

Aims: The objective of this work was to compare three algorithms in the diagnosis of drug hypersensitivity.

Objectives: The objectives of our study were to assess frequency, severity and outcome of renal abnormalities, as well as to determine the risk of developing hypophosphataemia in HIV-infected patients receiving tenofovir.

Methods: An observational study was conducted in real-life conditions, during a 6-month period, in 107 HIV patients receiving tenofovir.

Results: Mild-to-moderate hypophosphataemia (<0.

Persistent drug-induced movement disorders (tardive syndromes) remain an important clinical problem and consist of a variety of involuntary movements appearing in a patient exposed to a dopamine-blocking agent. The current state of knowledge on this topic is summarised in this article. Clinical aspects (tardive dyskinesia, tardive dystonia and other forms), prevalence, risk factors, prevention and management are discussed.

Objective: To report 2 cases of transitory cerebellar ataxia related to lidocaine administered topically for endoscopy. case summaries: Two patients developed transitory cerebellar ataxia a few minutes after local anesthesia using lidocaine 10% spray and lidocaine 2% orally for a bronchoscopy and transesophageal echocardiography. This effect completely disappeared in 3-5 hours.

Objective: To describe the time course and management of methotrexate (MTX) toxicity in a 14-year-old Hispanic boy with osteosarcoma treated with high-dose MTX.

Case Summary: During the sixth cycle of high-dose MTX, severe intoxication was observed with high MTX plasma concentrations, acute renal failure, and hepatitis, followed by mucositis and moderate myelosuppression. Intensification of urine alkalinization and increased leucovorin dosages did not decrease plasma concentrations of MTX or prevent systemic toxicities.

Background: Pancreatitis is the most severe complication of ERCP. The aim of this study was to assess whether the use of potentially pancreatotoxic drugs is a risk factor for post-ERCP pancreatitis.

Methods: Risk factors for post-ERCP pancreatitis and all drugs taken during the month before ERCP were recorded retrospectively in a database.
