[Women and alcohol, the addictologist's point of view and treatment]. / Les femmes et l'alcool, point de vue de l'addictologue et prise en charge.

Women have difficulty seeking help for alcohol-related problems. Shame and guilt are often present, which is why the caregiver must succeed in establishing a climate of trust so that things can be said, in order to best assess the impact of consumption and find alternatives. Treatment is often multidisciplinary. The nurse's role is essential, not only to identify drug use, but also to provide a link between the various players involved.

[Psychiatric complications of cannabis use]. / Complications psychiatriques de la consommation de cannabis.

Cannabis is the most widely used illicit substance, especially among young people. Cannabis use is extremely commonplace and frequently comorbid with psychiatric disorders that raise questions about the etiology. The use of cannabis is an aggravating factor of all psychiatric disorders. Psychiatric complications are related to the age of onset, duration of exposure and individual risk factors of the individual (mental and social health). The panic attack is the most common complication. The link with psychosis is narrow that leads to increased prevention for vulnerable populations. Cannabis is also an indicator of increased depressive vulnerability and an aggravating factor for bipolar disorder.

[Synthetic drugs: the new low-cost landscape of drugs]. / Drogues de synthèse: le nouveau cadre low-cost des drogues.

Designer drugs include, among others, synthetic cannabinoids and synthetic cathinones. These new "legal highs" drugs are sold on line for recreational public or private use. Synthetic cannabinoids are a psychoactive herbal and chemical product that, when used, mimics the effects of cannabis. Cathinone is a naturally occurring betaketone amphetamine analogue found in the leaves of the Catha edulis plant. Synthetic cathinones are phenylalkylamines derivatives, and may possess both amphetamine-like properties. They are often sold as "bath salts" or "plant food" and labeled "not for human consumption" to circumvent drug abuse legislation. The absence of legal risks, the ease of obtaining these drugs, the moderate cost, and the avaibility via Internet are the main criteria attracting the user. There is evidence that negative health and social consequences may occur in recreational and chronic users. The addictive potential of designer drugs is not weak. Furthermore, there is a lack of epidemiological, pharmacological, animal, clinical, psychological and therapeutic data concerning these new synthetic agents.

[Substance abuse among health personnel, defense or temptation?]. / La consommation de substances à l'hôpital, rempart ou tentation?

The increase of the psychological burden at work influences the consumption of substances, notably tobacco and alcohol. Healthcare workers are in a high-risk sector where we observe increasing malaise. A model of prevention and support with the treatment of staff members' addictions has been put in place within the Paris public hospital system (AP-HP): the Fides mission.

Use of psychoactive substances by night-shift hospital healthcare workers during the first wave of the COVID-19 pandemic: a cross-sectional study based in Parisian public hospitals (ALADDIN).

OBJECTIVES: This study aimed to estimate the prevalence of psychoactive substance (PAS) use in night-shift healthcare workers (NSHW) during France's first COVID-19 wave (March-May 2020). DESIGN: Observational cross-sectional online survey. SETTING: 39 public hospitals in the Assitance Publique des Hôpitaux de Paris (AP-HP) network in the Parisian area. PARTICIPANTS: A total of 1238 nurses, assistant nurses, X-ray technicians, managers, lab technicians, midwives and childcare assistants working at night or alternating between days and nights answered the questionnaire. INTERVENTION: Online survey. OUTCOME MEASURES: PAS use prevalence after weighting data for sex, age and profession using calibration on margins, in order to be representative of all AP-HP NSHW. We used the Fagerström scale and the Alcohol Use Disorders Identification Test Concise to assess PAS use. RESULTS: The weighted estimated prevalences of daily smoking, alcohol drinking and tranquilliser use in participating NSHW were 21.4, 1.3 and 2.4%, respectively. Twelve per cent (11.7%) of our study sample used opioids. During the first COVID-19 wave, PAS use remained stable except for tobacco use, with 8.6% of participants reporting an increase. Previous 3-month prevalences of tranquilliser and opioid use were significantly higher than in the general population. CONCLUSION: Daily smoking (especially in younger men) and tranquilliser and opioid use were highly prevalent in NSHW in the AP-HP network during France's first COVID-19 wave. Specific interventions for quitting smoking and addressing determinants of tranquilliser and opioid use in NSHW need to be developed and evaluated to improve quality of life in these essential, underdiagnosed and undertreated health personnel.

[Complications of cocaine addiction]. / L'addiction à la cocaïne: de nombreuses conséquences.

Addiction is a chronic relapsing disorder characterized by repetitive and compulsive drug-seeking behavior and drug abuse despite negative health or social consequences. Cocaine addiction is a significant worldwide public health problem, which has somatic, psychological, psychiatric, socio-economic and judicial complications. Some of the most frequent complications are cardiovascular effects (acute coronary syndrome, cardiac arrhythmias, increased blood pressure); respiratory effects (fibrosis, interstitial pneumonitis, pulmonary hypertension, alveolar haemorrhage, asthma exacerbation; emphysema), neurological effects (strokes, aneurysms, seizures, headaches); risk for contracting HIV/AIDS, hepatitis B and C, sexual transmitted disease and otolaryngologic effects. Other complications are not discussed here. The vast majority of studies indicate that there are cognitive deficits induced by cocaine addiction. Attention, visual and working memories, executive functioning are affected in cocaine users. Psychiatric complications found in clinical practice are major depressive disorders, cocaine-induced paranoia, cocaine-induced compulsive foraging and panic attacks.

Self-mutilation induced by cocaine abuse: the pleasure of bleeding.

INTRODUCTION: Self-mutilation is direct and deliberate harm to one's body without conscious intent to die. It is observed in both men and women with various psychiatric disorders, but most of those who self-mutilate are women diagnosed with borderline personality disorder. Cocaine addiction is a significant worldwide public health problem, associated with somatic, psychological, psychiatric, socioeconomic and legal complications. Amphetamine use, but not cocaine use, has previously been associated with severe self-injurious behavior. CASE: We report here a case of a female patient with recurring self-injurious behavior ("the pleasure of bleeding") induced by cocaine abuse. DISCUSSION: The clinical characteristics of self-mutilation are manifold and there is a lack of agreement about its etiology. The complex behavior associated with cocaine abuse may be one cause of self-mutilation. Dysfunction of the inhibitory brain circuitry caused by drug addiction could explain why this cocaine-addicted patient loses control and self-mutilates during cocaine use.

[Synthetic cannabinoids: A new addiction matrix]. / Cannabinoïdes de synthèse : une nouvelle matrice des addictions.

Synthetic cannabinoids (SC) belong to the emergent market of new psychoactive substances, sold on the Internet or specialized shops. Since the 1970s, more than 160 new SC have invaded the drug market. These substances imitate the psychoactive effects of cannabis. Underestimated for too long, SC's market growth and consequences are no longer to be ignored, first of all in terms of public health. SC were first synthesized during researches on the endocannabinoid system. Though they are agonists of the cannabinoid receptors 1 and 2, as Δ9-tetrahydrocannabinol in cannabis, they can also have a really high affinity with these receptors, rising up their potency. Each country in the world has chosen various ways how to deal with SC: scheduling, blanket ban, regulation… In order to contour the legal system, producers regularly modify the chemical formulas of those substances and hand out an attracting packaging looking harmless. However, the content of those small packets is extremely unstable and unreliable, including harmful compounds to health. Reports show an increasing number of non-fatal intoxications but also fatalities. Consequences on the body are numerous but there have been also reports of mental health imbalance and appearances of addiction-linked clinical signs. This review of literature aims at establishing a picture on SC in order to raise awareness among professionals in the health field on this new addiction matrix.

[Progressive cannabis-induced arteritis: a clinical thromboangiitis obliterans sub-group?]. / L'artérite progressive cannabique, un sous-type clinique de la thromboangéite oblitérante?

INTRODUCTION: Since the end of the nineteen-nineties, cannabis is not only incriminated in the onset of thromboangiitis obliterans but also in inducing artheromatous lesions in young subjects. OBSERVATION: A young, Caucasian, 18 year-old man was referred for cannabis withdrawal in the treatment of arteritis of the left leg. DISCUSSION: Cannabis is by far the illicite psychoactive substance most consumed by the 15-25 year-olds. Data in the literature, notably since the end of the nineteen-nineties, show that cannabis is accused of provoking arterial disease similar to that which is found in Buerger's disease (or thromboangiitis obliterans) in young subjects of whichever sex.

[Tobacco use and illicit substance use disorders: what should we have to do?]. / Consommation de tabac et trouble lié à l'usage de substances illicites: que devrions-nous faire ?

UNLABELLED: Tobacco use is a commonplace phenomenon in our society. Its use is responsible for more death and disease than any other noninfectious cause. More deaths are caused each year by tobacco use than by all deaths from HIV, illegal drug use, alcohol use, motor vehicle injuries, suicides, and murders combined. Tobacco remains responsible for greater morbidity than alcohol and all other drugs combined. Tobacco dependence is highly prevalent among drug-dependent patients. Substance abuse patients smoke more and are more vulnerable to the effects of smoking than general populations. Traditional substance abuse therapeutic programs too frequently focus only on treatment of alcohol or other drugs rather than including treatment for tobacco dependence. Currently, there are no official medical recommendations for the treatment of tobacco addiction in illicit polysubstance users. METHODS: A comprehensive literature search from a range of electronic databases (PubMed, Embase, PsycInfo, Google Scholar) was conducted for the period from 1988 to September 2012, using the following keywords alone or in combination: tobacco, nicotine, cocaine, cannabis, amphetamines, opiates, substance abuse, substance dependence, addiction, treatment. There were no restrictions on the identification or inclusion of studies in terms of publication status, language and design type. RESULTS: Our literature review will focus on epidemiological, neurobiological, clinical interactions between tobacco, alcohol and other illicit drugs. It will also focus on therapeutic programs in this dual addictive disorder. The aim of this literature review is to make proposals for the treatment of tobacco addiction in polysubstance users entering in specific therapeutic programs.

[Addiction to cocaine: a risk factor for suicide?]. / Addiction à la cocaïne: un facteur de risque de suicide ?

Cocaine is an illicit substance which is the greatest suicide-induced potential. Studies show a link between cocaine dependence and suicide. The prevalence of its use, in the days leading up to a suicide, may vary as between 9.4 and 20% according to the chosen method. The number of suicides is important. The acting out may be present at all stages of the addictive cycle associated with cocaine. On the 12th National Day on Suicide Prevention devoted to addictions and suicide, it was recommended that addictive phenomena should be taken more into account by experts in the subject, and that the risk of suicide should be evaluated by specialists in addiction in order that people presenting a risk be placed in appropriate preventative care in time.

[Current pharmacotherapies and immunotherapy in cocaine addiction]. / Pharmacothérapies actuelles et immunothérapie dans l'addiction à la cocaïne.

Cocaine is more and more used and abused in France. Cocaine dependence is quite serious and is associated with numerous adverse health consequences. No effective pharmacotherapy for cocaine dependence is yet available. Recent advances in neurobiology, brain imaging and some clinical trials suggest that certain medications that modulate GABAergic, dopaminergic, and glutamatergic systems, as well as immunotherapy, show promise in the treatment of cocaine addiction. Recent controlled clinical studies have tested some of these drugs, which act on the various neurobiological circuits modified by cocaine exposure and clinically improve patients' symptoms. Pharmacological agents such as modafinil, GABAergic agents (baclofen, topiramate, tiagabin, and vigabatrin), disulfiram, aripiprazole, N-acetylcysteine and cocaine vaccine seem very promising in the treatment of cocaine dependence. However, this must be confirmed in larger patient populations.

New treatments for cocaine dependence: a focused review.

Cocaine, already a significant drug problem in North and South America, has become a more prominent part of the European drug scene. Cocaine dependence has major somatic, psychological, psychiatric, socio-economic, and legal implications. No specific effective pharmacological treatment exists for cocaine dependence. Recent advances in neurobiology have identified various neuronal mechanisms implicated in cocaine addiction and suggested several promising pharmacological approaches. Data were obtained from Medline, EMBASE, and PsycINFO searches of English-language articles published between 1985 and June 2007 using the key words: cocaine, addiction, cocaine dependence, clinical trials, pharmacotherapy(ies) singly and in combination. Large well-controlled studies with appropriate statistical methods were preferred. Pharmacological agents such as GABA agents (topiramate, tiagabine, baclofen and vigabatrin) and agonist replacement agents (modafinil, disulfiram, methylphenidate) seem to be the most promising in treatment of cocaine dependence. The results from trials of first- and second-generation neuroleptics are largely negative. Aripiprazole, a partial dopaminergic agonist that may modulate the serotonergic system, shows some promise. Preliminary results of human studies with anti-cocaine vaccine, N-acetylcysteine, and ondansetron, are promising, as are several compounds in preclinical development. While no medication has received regulatory approval for the treatment of cocaine dependence, several medications marketed for other indications have shown efficacy in clinical trials. An anti-cocaine vaccine and several compounds in preclinical development have also shown promise. Findings from early clinical trials must be confirmed in larger, less selective patient populations.
