Abstract
Ketamine is an anaesthetic used in human medicine and veterinary practice, synthesised on 1962 and marketed on 1970 in France. Recreational uses were described during 1992 in the medical communauty and in 1996 in the dance settings. The chemical name of ketamine is 2 - (2chlorophenyl) 2-(methylamine)-cyclohexanone, an aryl cyclohexylamine, structurally related to phencyclidine. Ketamine is known under the following street names : Keta K, Kate, Special K, Vitamine K, la Golden, la Vétérinaire. Ketamine is used intranasally, orally and intramusculary in recreational use. Ketamine is manufactured by the chemical industry. Due to the complicated synthesis, it is sold illicitly for recreational use. Ketamine is a dissociative drug, and the user enters in a psychedelic dream with hallucinations, floating sensation, feeling of dissociation of the mind from the body. The dream is forgotten, the user fulls in reality with loss of self control, risk of acute intoxication. In long term exposure, tolerance, dependence, withdrawal signs and flash back are described. Ketamine trademarks are subject to control in France through medicine legislation Ketamine and its salts are subject to control under the national legislation on narcotics and psychotropics substance. From September 2001, the theft of medical and veterinary trademarks have to be declared to police, care health authority Pharmacy control authority and French Health Products Safety Agency.

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.

Abstract
OBJECTIVE Lithium is used for control of bipolar disorders. In order to precise the different circumstances at the origin of poisonings, the authors present the cases of lithium intoxication observed in the Marseille poison centre between January 1991 and December 2000. STUDY DESIGN Retrospective study. METHODS Three hundred and four cases were observed during the studied period (1 patient a case), concerning 6 different circumstances. For 3 of them, the symptoms were mild: accidental ingestion with children (13 cases); mistakes on the quantities of ingested tablets (43 cases); elevation of lithium blood level due to diuretic therapy (8 cases). For 2 other circumstances, the clinical signs were more severe: treated patients who developed renal failure (15 cases, 6 patients managed in intensive care unit [ICU], 1 death) or dehydration (35 cases, 8 patients treated in ICU and 1 death). Finally, the most severe cases were collected with suicide attempts. Fifty-six percent of the patients were managed in ICU, 5% needed haemodialysis, 10% had cardiac (repolarization disturbances) or neurological (seizures) complications, 2% died. CONCLUSION The severity of lithium poisonings depends of the circumstances. Ingestion of high quantities of sustained released tablets is the most dangerous situation. Accidental ingestion, even with children, must be considered as less severe situations.

Abstract
OBJECTIVE Report the experience of the Marseille's anti-poison center with lead poisoning adults. PATIENTS AND METHODS Between 1993 and 2000, 45 adults patients consulted the poison Centre of Marseille for a history of lead exposure (9 women, 36 men, average age 44 YO, between 22 an 76 YO). The lead sources were mostly occupational (welding, heavy metal industries...), but some were environmental (shooting as a hobby, hunting,...). RESULTS Ninety-one percent of the patients presented with a clinical feature of possible lead intoxication (asthenia, abdominal pain, anaemia, seizures,...). For 22 patients, calcitetracemate provocation test was negative. 6 patients with a positive test refused to be treated. 16 patients with a positive test were treated with chelation therapy (average lead blood level 566 micrograms/l--mini 320 micrograms/l, maxi 943 micrograms/l--and average lead urine elimination 3,011 micrograms/24 H--mini 789 micrograms/24 H, maxi 7,229 micrograms/24 H. 58 cures were done (1 to 12 cures for each patient). The average quantities of lead eliminated in the urine during the chelation therapy was 30,912 micrograms +/- 29,059 micrograms by case. For 12 patients who stopped the lead exposure after the diagnosis of lead poisoning, the chelaion therapy permitted to decrease the lead blood level of 69%. For 4 patients still exposed during the treatment, the lead blood level decrease of 7% only. For the 16 treated patiEnts, a clinical improvement was noted, and no adverse effects of chelation therapy was observed during the 58 cures.

Abstract
OBJECTIVE To study the doping substances used in sport and their toxicity. METHODS Retrospective analysis from January 1992 to December 2000 of the cases of use of doping substances in sport reported by telephone to the anti-poison center in Marseilles. RESULTS Fifty-one cases were reported concerning 48 men and 3 women with a mean age of 30, ranging from 10 to 55 years. Sixty-three percent of cases were reported over the last four years. The sport practiced was bodybuilding, except in 2 cases (cycling in one case and running in the other). The products used were mainly anabolizing hormones (15 times), clenbuterol (14 times) and creatine (7 times). A third of cases concerned associations of substances and 19 cases presented with symptomatology. CONCLUSION The diversity in nature and status of the substances mentioned and their association requires enhanced vigilance with regard to the use of drugs in sport. The recent measures voted within the framework of the anti-doping law dated 23/3/99 are aimed at increasing surveillance with the development of anti-doping antennae.

Abstract
A 54-y-old man ingested 2 g of bulk laboratory diazepam and was treated with activated charcoal, enhanced diuresis and flumazenil infusion. The treatment resulted in awakening, but the patient had drowsiness, dysarthria, diplopia, and dizziness for 9 d. Blood levels of diazepam and its main metabolite, nordiazepam, were obtained for 1 mo. The half-lives in this benzodiazepine overdose were longer than those seen with therapeutic doses. Benzodiazepines should not be readministrated when patients awake after suicide attempts.

Abstract
The maximum tolerated dose of paclitaxel administered by 24-hour continuous infusion in children is known. Short infusion might offer equivalent antitumour efficacy and reduced haematological toxicity, without increasing the allergic risk. Our aims were to determine the maximum tolerated dose and the pharmacokinetics of paclitaxel in children when administered in 3-h infusion every 3 weeks. Patients older than 6 months, younger than 20 years with refractory malignant solid tumours were eligible when they satisfied standard haematological, renal, hepatic and cardiologic inclusion criteria with life expectancy exceeding 8 weeks. Paclitaxel was administered as a 3-hour infusion after premedication (dexamethasone, dexchlorpheniramine). Pharmacokinetic analysis and solvent assays (ethanol, cremophor) were performed during the first course. 20 courses were studied in 17 patients; 4 dosage levels were investigated (240 to 420 mg/m(2)). No dose-limiting haematological toxicity was observed. Severe acute neurological and allergic toxicity was encountered. One treatment-related death occurred just after the infusion at the highest dosage. Delayed peripheral neurotoxicity and moderate allergic reactions were also encountered. Pharmacokinetic analysis showed dose-dependent clearance of paclitaxel and elevated blood ethanol and Cremophor EL levels. Although no limiting haematological toxicity was reached, we do not recommend this paclitaxel schedule in children because of its acute neurological toxicity.

Abstract
To evaluate the frequency and severity of accidental poisoning in children by narcotics or buprenorphine, a retrospective study was carried out: 75 cases were collected by the Marseille Poison Centre between 1993 and 1999. Most of the patients were between 1 and 3 years old and the drugs involved were cannabis and, more recently, Subutex (buprenorphine). These two drugs were responsible for the most severe cases of poisoning, most of which occurred at home.

Abstract
During the 6 months following the child-proof top commercialisation for the paediatric syrup EFFERALGAN in France, 51 cases of accidental ingestion were collected by the Marseilles Poison Centre. For 21 pour cent of them, the alleged dose taken was greater than the toxic dose. For 2 cases only, the responsible bottle had a child-proof top and was open on the table. For all other cases, it was simple-opening bottles (old bottles still present in houses, or bottles without a special top but sold in order to get rid of stocks). This study proves that such a preventive measure (modification of the top of the syrup bottles) is only fully effective if additional measures are undertaken such as return of unsold stocks or the provision of information to pharmacists and physicians.

Abstract
We describe a five-week-old boy who had seizures and extreme hypernatraemia secondary to ingesting an improper home-made formula. Initial sodium concentration was 211 mmol.l-1. Other clinical and biological features were moderate dehydration and renal insufficiency with generous urine output and high urinary sodium concentration. Fluid therapy with hypotonic dextrose solution corrected the volume deficit in 48 h and progressively decreased the serum sodium concentration. During ICU stay the patient developed recurrent episodes of seizures and pulmonary oedema requiring mechanical ventilation for five days. Recovery was complete with no abnormal sequelae after a ten-month follow-up. Salt poisoning is in unusual cause of extreme hypernatraemia. It can be safely managed with fluid therapy alone if urine output is preserved, with progressive decrease of serum sodium as target. If this condition is recognized, outcome should be favourable.

Abstract
In 1998, 77 cases of accidental ingestion of paracetamol paediatric syrup (Efferalgan) in children were notified to the Marseille Poison Centre. In a quarter of them, the alleged dose taken was greater than the toxic dose. Ingestion was mainly due to the child opening the bottle. The proximate marketing of a product with a child-proof top, which should allow the number of accidents to be reduced. Doctors and pharmacists should be informed rapidly, so that they can warn the families who still have the old type of bottle.

Abstract
Méthamidophos is an organophosphorus insecticide which delayed neurotoxicity is more frequent than with other organophosphates. Authors present a case report concerning a collective poisoning after cutaneous contact: two farm labourers presented moderate cholinergic signs quickly followed by proximal neurological signs (retrobulbar ocular neuritis for one patient, thight paresthesias for the second one). These signs decreased meanwhile new neurological symptoms appeared: sensory and motor peripheral neuropathy in both patients, with a clinical aspect of OrganoPhosphorus Induced Delayed Neuropathy (OPIDN). This unusual chronology and the disappearence of all signs at the 18th month, lead the authors to diagnose a collective methamidophos poisoning in three phases: first, anticholinesterasic acute syndrome; second, an intermediate syndrome and third an OPIDN.

Abstract
The aim of this study was to identify the latest trends in psychotropic drug use and the effect of the increase of maintenance treatments for serious opioid addiction. The results are based on data from OPPIDUM, an annual survey primarily concerned with the consumption of licit and illicit drugs. The study involved 1066 drug addicts recruited during the month of October 1997 from 38 French health centres connected with the Centres for Evaluation and Information on Drug Addiction (CEIP). The most frequently reported drugs were benzodiazepines (n = 323), some of which, especially flunitrazepam (Rohypnol, n = 123), are extremely addictive. The data showed a slight decrease in heroin consumption as well as a marked increase in the use of maintenance treatments. The association between benzodiazepines and buprenorphine (Subutex) should consequently be studied, whether buprenorphine is being used illicitly or prescribed as a maintenance treatment.

Abstract
In southern France, some Amanita species are usually eaten like Amanita ovoidea (Quélet, 1872) which is a common white mushroom. In same areas, a similar and less common fungus can be encountered: Amanita proxima (Dumee, 1916). The first published cases of Amanita proxima poisonings with acute renal failure have been reported in 1994 by a medical team from Montpellier. A second article was published in 1995 by physicians from Marseille. In order to evaluate the importance of the confusion between the 2 species, we looked after these mushroom poisonings collected by the Poison Centre of Marseille. We found 31 cases concerning 53 patients. We observed the first intoxication in 1968. Poisonings took place in the south of Provence. Ingestions are in 26 cases (83% of the 31 cases) due to the confusion with Amanita ovoidea. The average delay between the meal and the first signs was 13 hours and 12 minutes. All patients had gastro-intestinal symptoms, and for 14 of them, oliguria or anuria appeared in a few days after ingestion. 11 patients needed temporary dialysis, and for 10 of them, moderate hepatic cytolysis was observed. The severity of symptoms seems to be dose-dependent: we collected cases in the same family with no signs after just tasting the meal, digestive symptoms only when patients at more, and renal failure for the hungry people.

Abstract
Following the setting up by the Government of their project for the management of drug addicts, and under the guidance of the CEIP (Centre d'Evaluation et d'Information sur les Pharmacodépendances [Centre for Evaluation and Information on Drug Addiction]) in Marseille, a survey of prescriptions written on controlled-drug prescription pads was performed. The aims were threefold: to study the medicines prescribed, to follow up the legislation and to inform doctors and pharmacists. Copies of the prescriptions, dated between 1 January 1996 and 30 June 1996, which were sent by 81 per cent of the 216 pharmacies contacted in 15 towns in the Provence-Alpes-Côte d'Azur (PACA) region were studied. Various criteria, relating to writing of the prescriptions and distribution of the medicines to the patients, were coded and analysed. This survey showed that of 4 prescriptions, 3 were prescribed for maintenance and one for analgesic therapy. The patients receiving maintenance therapy were male in three-quarters of the cases, and were around 30 years old. Analgesics were prescribed in equal proportions for patients of both sexes, who were around 65 years old. Since it was put on the market, Subutex has been quickly prescribed.

Abstract
BACKGROUND Nasal foreign body (NFB) is a common situation in pediatrics. Poisoning is a rare complication of NFB insertion. We report a case of acute potassium dichromate poisoning secondary to NFB insertion. CASE REPORT Six days after insertion of a NFB, progressive occurrence of diarrhea, vomiting, nasal obstruction, acute renal failure, pancreatitis, hepatitis and drowsiness justified hospitalization of a 3-year-old girl in the pediatric intensive care unit. Acute potassium dichromate poisoning was confirmed by high plasma chromium level and by the spectrophotometric analysis of the crystal. Recovery was satisfactory with supportive treatment. An official survey allowed to discover that the crystal was freely sold and that its toxicity was unknown by dealers, while no information was given to the customers. CONCLUSION Transmucosal absorption of toxics is an unusual severe potential hazard that should be evoked to allow a rapid management. After the discovery and withdrawal of a NFB, occurrence of systemic symptoms, even trivial, must make one suspect a poisoning. In this circumstance, analysis of the foreign body should be done, associated with toxicologic dosages. This case report illustrates that potassium dichromate poisoning is a severe medical condition and that its clinical presentation assume a large widespread of symptoms due to multiple organ involvement.

Abstract
BACKGROUND Urinary detection of prenatal drug exposure in the neonate may give false-negative results. We report our experience on meconium and hair testing, in addition to urine testing in order to improve diagnosis of fetal drug exposure. POPULATION AND METHODS Thirty-one infants (aged 1-45 days) whose mothers were confirmed (n = 12) or suspected (n = 19) to be drug-addicted were included in the study. One or more specimens of urine, meconium or hair were collected in the 31 infants, two of the specimens in 17 and three in six. Drugs and their metabolites were detected by immunoenzymologic techniques and positive results were confirmed by gas-exchange chromatography. All the mothers and families were interviewed during admission and the information was compared to those provided by medical and social services; the results of laboratory analysis were not known by the investigators at this time of the study. RESULTS The maternal drug addiction was confirmed after clinical investigation in 18 cases including the 12 cases detected by prenatal interview (group 1), and recused in 13 other cases (group 2). In group 1, nine infants of 12 had a positive urine test (seven opiate, one cocaine, one cannabis), 11 of 11 a positive meconium test (nine opiate, one cocaine, one cannabis), ten of 19 a positive hair test (eight opiate, one cocaine, one cannabis); all infants in this group had at least one positive result. In group 2, all tests were negative except one urine test positive for opiate after cesarean delivery performed under anesthesia including opiate analgesia. CONCLUSIONS Urine, meconium and hair testing versus urine testing alone increase the sensitivity of laboratory analysis for detection of prenatal drug exposure.

Abstract
A 35-year-old male nurse hospitalized for recurrent episodes of intolerable abdominal pain was found to have non-hemolytic anemia and saturnism with blood lead level reaching 500 micrograms/l. Search for the source of the lead led to the discovery of an earthenware jug purchased in a Corsica craftsware shop. This jug had been used to hold the patient's daily consumption of wine (estimated at one-half to three-quarters liters per day) in the refrigerator. On the basis of lead release measurements using the method described in the EEC directive 84/500 (maximum tolerated limit for crockery = 4 mg lead/litter contents), it was found that the jug released 216 mg/l and estimated that the patient had ingested 0.8 to 1 mg of soluble lead daily for the past 8 years. The patient was successfully treated with chelator agents. This case of lead poisoning caused by a single earthenware wine jug confirms the need for rigourous governmental directives to control the production and distribution of varnished earthenware.

[Bradycardia during treatments of weight loss]. Presse Med 1995; 24:1260-2.

Abstract
Sinus bradycardia was observed in 10 adolescents participating in a weight loss diet conducted in a health centre. The precise cause was assessed. The subject's age ranged from 10 to 15 years and weight loss ranged from 8 to 24 kg over a period ranging from 8 to 23 weeks. None of the subjects had taken drugs with a bradycardic effect and search for toxic agents in the blood and urine was negative in all cases. Infection was suggested since 8 of the 10 adolescents had a rhinopharyngitis a few weeks before the discovery of bradycardia. This cause was not retained due to the lack of any signs of infection or inflammation and negative virus serology. Nutritional status was therefore retained as the most likely cause in these adolescents who were eating a diet containing < or = 1350 kcal/day. This hypothesis was supported by the results of work reported in 1970 showing arrhythmia in very low calorie diets. The effect is essentially related to the biological value of proteins in the diet, its duration and the initial weight of the subjects. In addition bradycardia is frequently seen in subjects taking hypocaloric diets or with anorexia nervosa and should be considered as an adaptation to hypometabolism rather than a true heart disorder. Thus the biological value of the proteins and the mineral status should be taken into consideration during the course of low calorie diets, even though bradycardia is frequent and does not require a specific treatment. Therefore heart rate and decreasing rate of weight loss should be carefully followed during the course of low calorie diets.

Abstract
A study of benzodiazepine impregnation of 234 drivers involved in road accidents showed a higher level of impregnation than that usually observed in the general population and a different frequency of this impregnation in the two populations. Although a significant correlation was found between responsibility of the driver and positivity of benzodiazepine assays, this result must be interpreted with caution and does not permit to attribute the responsibility for the accident to the presence of benzodiazepine in blood.

Abstract
Buprenorphine, a synthetic central analgesic, marketed since 1987, was rapidly suspected to be subject to abuse. We tried to confirm this abuse in the context of our analytical activity at the Drug Dependence Evaluation and Information Centre. The study was based on 50 drug addicts admitted to Marseille Hospital between June and October 1992. Buprenorphine and its N-dealkylated metabolite were identified in the urine by high performance liquid chromatography equipped with a diode array detector. Nine (18%) of the 50 samples analysed were positive for buprenorphine and/or norbuprenorphine, with a confidence interval of 8 to 28%, which confirms the existence of abuse of this analgesic.

Abstract
Axillary buds of taro (Colocasia esculenta var. esculenta, Araceae) cultured on half strength Murashige-Skoog medium (HMS) containing taro extract (HMSTE) and 2, 4, 5-trichlorophenoxyacetic acid produce a compact, hard, slow growing callus which is not very active morphogenetically and produces only a few plantlets. When cultured on HMSTE plus 5 mg 1(-1) each of naphthaleneacetic acid and benzyl adenine (HMSNB) the buds produce a fast growing, friable and morphogenetically active callus. Meristematic regions form on the friable callus after 30 days on HMSNB. If transferred to HMSTE at this point the callus gives rise to plantlets. Addition of taro extract to the media is required for the culture of buds, induction of callus and plantlet regeneration.

Abstract
Axillary bud expiants from South Pacific (Solomon Islands) taro, Colocasia esculenta var. esculenta cv. Akalomamale (Araceae) cultured on a modified Murashige-Skoog medium containing 1 mg NAA 1(-1) and TE formed callus and produced multiple plantlets. Explants died if NAA was present at levels lower than 0.1 mg 1(-1). BA was not required and may have been inhibitory. Plantlets developed faster and became larger following transfer to a hormone-free medium two weeks after the start of culture. Fully grown plants were established in a potting mix and are growing well in a greenhouse.

Abstract
Local anesthesia for ambulatory phlebectomy makes it necessary to inject a considerable quantity of lidocaine. This study involved 50 operations. The doses of lidocaine containing 1% adrenaline and injected after cooling (between 2 and 5 degrees C) ranged from 200 mg to nearly 900 mg in a single administration. The assays of lidocaine in the peripheral venous blood were carried out by means of F.P.I.A. (Fluorescence Polarization Immuno Assay) at times 0, 30 min 60 min, 90 min., 24 hours and 48 hours. The peak concentration obtained (1.8 micrograms/ml) for a dose of 700 mg in a subject weighting 65 kg, i.e. 10.9 mg/kg, was only one-half the concentration considered to be neurologically toxic (4 to 12 micrograms/ml) or one-twelfth of the toxic levels with regard to the cardiovascular system (24 micrograms/ml). The performance of local anesthesia in the physician's office is devoid of major risks, even though the doses used during AP are much higher than those usually administered in routine dematological surgery.

Abstract
Excised lateral buds of taro [Colocasia esculenta var. esculenta (L.) A.F. Hill] developed into plantlets and formed callus if cultured on media containing taro extract. α-Naphthaleneacetic acid enhanced the process but only if taro extract was also present. The tissue requirements for this variety of taro are different from those of Colocasia esculenta var. antiquorum (L.) A.F. Hill.
