European Council of Legal Medicine (ECLM) accreditation of forensic pathology services in Europe.

Forensic experts play a major role in the legal process as they offer professional expert opinion and evidence within the criminal justice system adjudicating on the innocence or alleged guilt of an accused person. In this respect, medico-legal examination is an essential part of the investigation process, determining in a scientific way the cause(s) and manner of unexpected and/or unnatural death or bringing clinical evidence in case of physical, psychological, or sexual abuse in living people. From a legal perspective, these types of investigation must meet international standards, i.e., it should be independent, effective, and prompt. Ideally, the investigations should be conducted by board-certified experts in forensic medicine, endowed with a solid experience in this field, without any hierarchical relationship with the prosecuting authorities and having access to appropriate facilities in order to provide forensic reports of high quality. In this respect, there is a need for any private or public national or international authority including non-governmental organizations seeking experts qualified in forensic medicine to have at disposal a list of specialists working in accordance with high standards of professional performance within forensic pathology services that have been successfully submitted to an official accreditation/certification process using valid and acceptable criteria. To reach this goal, the National Association of Medical Examiners (NAME) has elaborated an accreditation/certification checklist which should be served as decision-making support to assist inspectors appointed to evaluate applicants. In the same spirit than NAME Accreditation Standards, European Council of Legal Medicine (ECLM) board decided to set up an ad hoc working group with the mission to elaborate an accreditation/certification procedure similar to the NAME's one but taking into account the realities of forensic medicine practices in Europe and restricted to post-mortem investigations. This accreditation process applies to services and not to individual practitioners by emphasizing policies and procedures rather than professional performance. In addition, the standards to be complied with should be considered as the minimum standards needed to get the recognition of performing and reliable forensic pathology service.

The spectrum of acute heart failure after venlafaxine overdose.

OBJECTIVE: Venlafaxine is a bicyclic antidepressant that may be associated with severe cardiotoxicity following large overdose. The purpose of this short case series is to present different patterns of venlafaxine-related cardiotoxicity and to discuss the potential mechanisms. CASE SERIES: Between January 2010 and July 2011, four patients were admitted to an ICU with acute left ventricular failure following large venlafaxine overdoses. The age of the four female patients ranged from 35 to 65 years. None of them had no history of cardiovascular disease. The amount of venlafaxine ingested by history ranged from 3150 to 13500 mg (extended-release preparation in two cases). The peak serum venlafaxine concentration was between 2153.3 and 9950 ng/ml. Three patients died and one recovered rapidly. The initial ECG revealed only mild abnormalities in two cases. In two patients, at least one ECG recording demonstrated a widening of QRS interval. In three patients, echocardiography disclosed a left ejection fraction of 15%-18%. Two patients presented a severe serotonin syndrome, with major rhabdomyolysis. Seizures were noted in two cases, including one patient with status epilepticus. Three patients were mechanically ventilated. The causes of death were refractory hypoxemia, malignant arrhythmias, and cardiogenic shock, respectively. DISCUSSION: Severe and diffuse left ventricular dysfunction may be observed after large venlafaxine overdoses and this is not always associated with severe cardiac conduction function abnormalities. The mechanisms underlying venlafaxine-related cardiac failure with preserved normal cardiac conduction are discussed. A possible explanation may be a catecholamine-induced myocardial damage in relationship with the inhibition of norepinephrine (and dopamine) reuptake.
