Intoxications accidentelles par cannabis chez l’enfant : expérience du centre antipoison de Marseille

OBJECTIVE To assess the frequency and severity of accidental cannabis poisoning in children. METHODS A retrospective study of cases of accidental cannabis poisoning in people aged under 18 years old, reported to the Marseille poison center from 1993 through 2007. We excluded cases where cannabis was definitively ruled out, and neonatal withdrawal syndromes in newborns from cannabis users. RESULTS We collected 93 cases, including 56 boys and 37 girls, 86% of whom were younger than 3 years. The principal form was cannabis resin (hashish), reported in 80% of the cases and belonging to one of the parents or a household member. In almost all cases, the poisoning took place at the childs home. The frequency has risen in recent years, with 2/3 of the cases occurred in the second half of the study period. Five serious cases were reported, two with convulsions. CONCLUSION Considering the observed increase in cases each year, mostly benign but potentially serious, prevention and information efforts have to be improved for drug users with young children and for healthcare professionals led to manage this kind of accident.

Illicit drugs or medicines taken by parachuting

Parachuting (also called bombing) is a method of drug delivery where illicit drugs or medicines are ingested after wrapping the substance. There are little data describing parachuting in the literature. To provide a description of this practice, all cases of parachuting reported to the national addictovigilance network up to 31 December 2014 were identified from spontaneous reports and specific surveillance programs. Cases were described according to the type of substance used, patient age and gender, type of complications, context of use and year of the event. Forty‐five cases of parachute use were identified and most (n = 43) occurred after 2011. Patients were mostly men (60%), and mean age was 28.9 years. The context of use, known in 19 cases, was mostly recreational. Complications were present in 24 cases, of which eight were serious. The substance was supposed to be 3,4‐methylenedioxymethamphetamine (MDMA) in the majority of cases (64.4%); research chemicals were more involved in the most recent years. The physical form was mainly granular (51.6%). The wrappers were a cigarette paper (nine cases) and in one case plastic package; in the other cases, the term of parachute was used without further details. The reason for use was not explained in the majority of cases; two patients indicated using a parachute for faster effect than with a methadone capsule. Clinicians should be aware of this delivery form as the results suggest that it is common and can involve a great variability of drugs.

Cannabis body packing: Two case reports

Introduction. Body packing is a well-known means of narcotic carriage across international borders. The most common drugs carried are cocaine and heroin. Case descriptions. We describe 2 cases of cannabis body packing which occurred the same year in the South of France, one with complications: a 45-year-old male went to emergency for abdominal pain. A plain abdominal x-ray revealed multiple foreign bodies in the gastrointestinal tract. It was confirmed by abdominal CT. The laparatomy confirmed peritonitis secondary to colonic perforation, and 34 filled condoms packages were extracted. After calling poison centre, toxicological analysis was performed on one package. The resin wrapped in cellophane contained 15% tetrahydrocannabinol (THC). The patient was discharged on day 12. Discussion/Conclusion. Cannabis body packing is rarely reported, and the only known complications have a mechanic etiology. Plain abdominal x-ray is the best method for detection and it can be confirmed by abdominal CT and toxicological analysis. Cannabis is the most important illicit drug used in the word. Also cannabis body packing is probably underestimated. Health care practitioners should be aware of the possibility of body packing when someone coming back from abroad complains of abdominal pain.

Syndrome ischémique distal sévère après injection intra-artérielle volontaire de buprénorphine

High dosage buprenorphine (HDB) is a sublingual maintenance treatment of opioid dependence which have proved its substantial Public Health results, but it is also known to be frequently abused and diverted, in particular for intravenous injection, with deleterious consequences. Intra-arterial use is more rarely reported with this substance, just like its complications, mainly ischemic, potentially necrotic, phenomena. We report here such a case, with a 30 years-old man suffering from severe ischemia of the thumb, the forefinger and the middle finger few hours after direct injection of a suspension of buprenorphine crushed tablets in right radial arteria. A treatment combining surgery (video-thoracoscopic thoracic sympathectomy) and medicines (heparin, iloprost and piribedil mesilate), permitted a semi-complete digital rehabilitation (only forefinger pulp necrosis persisted and required a distal amputation), and the patient was discharged after 2 weeks.

Ma Huang, du complement alimentaire a l'abus.

Abstract Dietary supplements containing Ma Huang (chinease ephedra) are available on the web sites and dietary shops in USA. They are widely promoted and used as a mean of weight reduction and energy enhancement. They contain Ma Huang alone or combined with Guarana (caffeine), creatine, St Jonh’s wort, carnitine and are proposed with different labels. Numerous reports of adverse reactions and acute intoxication related to these products use were described in the medical literature. In the light of the severity of these cases, some of which resulted in permanent injury and death, the Food and Drug Administration has proposed limits on the dose and duration of use of such supplements. A review of 140 reports submitted to the FDA between June 1997 and March 1999, 47 % involved cardiovascular symptoms, 18 % neurological symptoms. Severe hypertension was the single most frequent adverse effect followed by tachycardia, myocardial infarction, stroke, seizure. Ten events resulted in death and 13 produced permanent impairment. In France, ampleness of the use of dietary supplements containing ephedra alkaloids is unknown. Two French recent severe poisonings (one with “ripped Fuel” for losing weight and the other with “Energy pills” in a body builder) show that there is serious health risks for the chronic users. Dietary supplements are not subject to control under “la Direction Générale de la Santé”. Informations for general public, medical community and health-care authorities are necessary to be aware of potential health hazards of these products use.

Cannabinoid hyperemesis syndrome: Review of the literature and of cases reported to the French addictovigilance network

BACKGROUND Cannabinoid hyperemesis syndrome is a variant of cyclical vomiting syndrome in a context of chronic cannabis usage. Our aim was to compare French cases to those identified in the international literature in order to further our knowledge of the clinical criteria, pathophysiology and treatments for cannabinoid hyperemesis syndrome. METHODS We analysed cases reported in the international literature up to 30 June 2017, obtained from the MEDLINE, PsycINFO and The Cochrane Library databases; we selected relevant articles based on title and abstract. We also analysed cases of cannabinoid hyperemesis syndrome reported to the French addictovigilance network. RESULTS A systematic search through the three databases enabled us to identify 137 articles. Finally, 55 articles were selected as they involved reported cases. In total, 113 cases were reported in these 55 articles. We were thus able to analyse 29 reported French cases of cannabinoid hyperemesis syndrome. Cannabinoid hyperemesis syndrome mainly affects young male subjects who have been smoking cannabis daily for several years. Taking hot baths or showers is the most effective means of relieving the symptoms, while antiemetics and dopamine antagonists do not appear to effective for relieving nausea and vomiting. CONCLUSIONS French cases display the same characteristics as the cases identified in the international literature. The pathophysiology of cannabinoid hyperemesis syndrome is unclear and several hypotheses have been put forward in the literature. We have only begun to characterise the syndrome, though there is an outbreak of cannabinoid hyperemesis syndrome in France.

Identification and tracking of Addictovigilance signals in general practice: which interactions between the general practitioners and the French Addictovigilance Network?

Addictovigilance is a health vigilance dedicated to the survey of medicinal or illicit psychoactive substance use disorders (SUDs). France is the only European country to have a vigilance system specifically dedicated to substances with an abuse/addiction potential. The French Addictovigilance system is organized in a network of regional tertiary centres (called Abuse and Dependence Monitoring Centres, CEIP‐Addictovigilance) and works in close collaboration with Regional and National health authorities. Because of the essential and unavoidable nature of their practice in the French Healthcare system, general practitioners (GPs) are key actors to identify and track Addictovigilance signals. They have been involved in several of the pharmacoepidemiological surveys implemented by the French Addictovigilance Network (FAN). Now, they increasingly participate in clinical research projects and studies. In this article, interactions between GPs and the FAN are illustrated with two examples: patients on opioid substitution treatment and patients on opioid analgesics. Collaborations between GPs and the FAN could be further potentiated. In particular, more effective communication on psychoactive SUDs including abuse/addiction is necessary to optimize the implementation of preventive measures for patients on psychoactive substances medications, and to improve the attitudes of GPs and more widely health professionals in the management of any psychoactive user suffering from SUDs. In addition, both adapted training and improved collaborative research could contribute to the optimization (safety, quality) of professional practices.
