Chemical submission to commit robbery: a series of involuntary intoxications with flunitrazepam in Asian travellers in Brussels.

Between January 17, 2003 and August 29, 2003, the Emergency Department admitted a patient who had been surreptitiously intoxicated and robbed of his valuables every Friday. The first cases were considered anecdotal, but criminal activity was rapidly suspected. The cohort includes 16 male Asian patients aged 28-50 years.

Carnitine in the treatment of valproic acid-induced toxicity.

Introduction: Valproic acid (VPA) is a broad-spectrum antiepileptic drug that is now used commonly for several other neurological and psychiatric indications. VPA is usually well tolerated, but serious complications, including hepatotoxicity and hyperammonemic encephalopathy, may occur. These complications may also arise following acute VPA overdose, the incidence of which is increasing.

Epigastric pain as presentation of an addisonian crisis in a patient with Schmidt syndrome.

A 39-year-old woman presented with a 10-day history of epigastric pain accompanied by persistent fatigue and loss of appetite for 3 months. She had presented several weeks earlier with adhesive capsulitis, treated by local infiltration of corticosteroids. She was not taking any other medications.

Seroprotection against tetanus in patients attending an emergency department in Belgium and evaluation of a bedside immunotest.

Background: In most emergency departments, tetanus prophylaxis currently relies on vaccination history. Bedside evaluation of tetanus immunity may improve this process.

Objectives: (i) To determine the seroprevalence of tetanus immunity; (ii) to evaluate the accuracy of vaccination history in assessing tetanus immunity; (iii) to identify factors predictive of seroprotection and incorrect history.

Assessment of pretest probability of pulmonary embolism in the emergency department by physicians in training using the Wells model.

Introduction: Assessment of pretest probability should be the initial step in investigation of patients with suspected pulmonary embolism (PE). In teaching hospitals physicians in training are often the first physicians to evaluate patients.

Objective: To evaluate the accuracy of pretest probability assessment of PE by physicians in training using the Wells clinical model and to assess the safety of a diagnostic strategy including pretest probability assessment.

Bench-to-bedside review: hyperinsulinaemia/euglycaemia therapy in the management of overdose of calcium-channel blockers.

Hyperinsulinaemia/euglycaemia therapy (HIET) consists of the infusion of high-dose regular insulin (usually 0.5 to 1 IU/kg per hour) combined with glucose to maintain euglycaemia. HIET has been proposed as an adjunctive approach in the management of overdose of calcium-channel blockers (CCBs).

Bench-to-bedside review: Antidotal treatment of sulfonylurea-induced hypoglycaemia with octreotide.

The major potential adverse effect of use of sulfonylurea agents (SUAs) is a hyperinsulinaemic state that causes hypoglycaemia. It may be observed during chronic therapeutic dosing, even with very low doses of a SUA, and especially in older patients. It may also result from accidental or intentional poisoning in both diabetic and nondiabetic patients.

Science review: carnitine in the treatment of valproic acid-induced toxicity - what is the evidence?

Valproic acid (VPA) is a broad-spectrum antiepileptic drug and is usually well tolerated, but rare serious complications may occur in some patients receiving VPA chronically, including haemorrhagic pancreatitis, bone marrow suppression, VPA-induced hepatotoxicity (VHT) and VPA-induced hyperammonaemic encephalopathy (VHE). Some data suggest that VHT and VHE may be promoted by carnitine deficiency. Acute VPA intoxication also occurs as a consequence of intentional or accidental overdose and its incidence is increasing, because of use of VPA in psychiatric disorders.

Pyridoxine in clinical toxicology: a review.

Pyridoxine (vitamin B6) is a co-factor in many enzymatic pathways involved in amino acid metabolism: the main biologically active form is pyridoxal 5-phosphate. Pyridoxine has been used as an antidote in acute intoxications, including isoniazid overdose, Gyromitra mushroom or false morrel (monomethylhydrazine) poisoning and hydrazine exposure. It is also recommended as a co-factor to improve the conversion of glyoxylic acid into glycine in ethylene glycol poisoning.

Management of new-onset atrial fibrillation in the emergency department: is there any predictive factor for early successful cardioversion?

Objectives: The aim of this retrospective study was to assess the initial management of atrial fibrillation (AF) in the emergency department (ED) and to identify predictive factors of early conversion to sinus rhythm, which could justify a short stay in the ED observation unit (EDOU) instead of longer hospitalization.

Patients And Methods: All patients with acute AF, either of new onset or recurrent, admitted to our hospital during a 12-month period were included in the study. Hospital records were reviewed retrospectively.
