Background: Health care seeking for a problematic use of cannabis is in progress in France., Objectives: The aim is to assess the addictive and psychiatric comorbidity in cannabis users seen in the specific setting at the Lariboisière hospital., Method: Two hundred and seven cannabis users were included from January 2004 to December 2009. Twelve-month and lifetime diagnosis of abuse and dependence (cannabis, alcohol, cocaine/crack) (DSM-IV), current and lifetime mood disorders, anxiety disorders, eating disorders and psychotic disorders were assessed (Mini-International Neuropsychiatric Interview). Logistic regression analyses identified adjusted odds ratios associated with the gender and the health care seeking (P=0.01)., Results: One hundred and forty-seven men (71%) and 60 women (29%), 29.3±8.6 years (15.2-51.6 years). Most of the outpatients ask for health care themselves (59.7%), whereas 19.4% are asked to seek health care by relatives (19.4%) or because of an academic, health or justice injunction (20.4%). In total, 49.3% of the outpatients are single, 35.7% are cohabitating, 9.3% are married and 6.3% are separated/divorced. About 20.4% of the outpatients are students, 35.7% have a professional activity, 19% are jobless, 2.4% are impaired, 0.5% are retired, at home and 12.1% do not have an official income. Twelve-month and lifetime prevalence of abuse/dependence are: cannabis (10.1/82.1% and 8.7/88.4%), alcohol (9.7/8.7% and 19.3/18.8%), cocaine/crack (2.4/3.4% and 4.8/11.6%). The mean duration of cannabis dependence for the current dependent users is 8.4±5.8 years. The mean number of "joints" during the last 6 months is 6±4.3, the mean amount of cannabis per week is 12.5±11.3g. About 51.3% of the dependent users report externalized and/or internalized disorders at school during childhood and adolescence. In total, 19.4% of the dependent users have a suicide attempt history and 18.9% have a psychiatric hospitalisation history, more frequently women (P<0.01 and P=0.02). About 73.8% have a psychologist or psychiatrist care history. In total, 38.1% of users have at least one current mood disorder, females more frequently than males (P<0.001). Current and lifetime prevalence of mood disorders are: major depressive disorder (MDD) (29.1% and 57.1%); current dysthymia (20.3%); hypomania (1.9 and 6.7%); mania (2.9 and 12.8%). Females have more frequently than males current and lifetime MDD (P<0.001). About 53.2% of users have at least one current anxiety disorder, females more frequently than males (P<0.001). Current and lifetime prevalence of anxiety disorders are: panic disorder (10 and 16.4%); agoraphobia (13.9 and 17.4%); social phobia (26.9 and 32.8%); obsessive-compulsive disorder (9.5 and 12.9%); post-traumatic stress disorder (PTSD) (6.5 and 16.4%); current generalized anxiety disorder (26.8%). Females have more frequently current and lifetime: agoraphobia (P=0.01 and P<0.001); PTSD (P<0.001); current social phobia (P=0.049). Current and lifetime eating disorders prevalence are: anorexia (0 and 1.5%); bulimia (4 and 8%); females more frequently have bulimia (P=0.02 and P<0.001). In total, 4.8% have a psychotic disorder. Adjusted odds ratios of associated variables to gender (women/men) are lifetime MDD OR=4.71 [2.1-10.61] (P<0.001) and later age of onset of cannabis abuse OR=1.1 [1.04-1.17] (P=0.002). Adjusted odds ratios associated with personal health care seeking compared to a non personal motivated health care seeking are the numbers of criteria of 12-month cannabis dependence OR=1.26 [1.06-1.51] (P=0.009) and age OR=1.07 [1.03-1.12] (P=0.002)., Conclusion: Our survey confirms the high mood and anxiety disorders comorbidity in cannabis dependent users seen in a specific setting and underlines the need to evaluate those disorders., (Copyright © 2014 L’Encéphale, Paris.

Background: The cannabis withdrawal syndrome occurs after cannabis cessation in more than 50% of dependent smokers. But although opioid-dependent patients are more frequently cannabis users and cannabis-dependent than the general population, the frequency and phenomenology of cannabis withdrawal symptoms in this specific population is unknown. Our hypothesis was that cannabis-dependent patients with current opioid dependence would experience the same withdrawal syndrome after cannabis cessation., Objective: To describe cannabis withdrawal symptoms in cannabis-only dependent patients and in cannabis-dependent patients with current opioid dependence., Methods: Using retrospective interviews, we evaluated the number and duration of six cannabis withdrawal symptoms in two groups: 56 cannabis-dependent patients without and 43 cannabis dependent patients with current opioid dependence. Cannabis and opioid dependence diagnoses were defined with DSM IV criteria using the MINI structured interview., Results: The two groups were not different in terms of age of onset of cannabis use, and number of cannabis joints smoked at the time of the cannabis cessation attempt. The frequency of a cannabis withdrawal syndrome (defined as at least two different symptoms) did not differ in the two groups (65%). Neither was the proportion of subjects with the following symptoms: appetite or weight loss (30.8%), irritability (45.1%), anxiety (56%), aggression (36.3%) and restlessness (45.1%). Patients with cannabis dependence and current opioid dependence were more likely to report sleep disturbances (79.1 vs. 53.6%, chi(2)=6.91, P=0.007). The median duration of this cannabis withdrawal syndrome was 20 days post-cessation., Conclusion: This is, to our knowledge, the first study describing cannabis withdrawal syndrome in cannabis-dependent patients with current opioid dependence. These patients experience a cannabis withdrawal syndrome as often as cannabis-only dependent subjects, but describe more frequently sleep disturbances. This high rate of sleep disturbances may cause relapse to cannabis use., (Copyright © 2010 L’Encéphale, Paris. All rights reserved.)

Context: In the 1990s, cannabis consumption in France increased considerably. So, in 10 years, the number of adolescents reporting regular cannabis use (10 or more times during the last 12 months) tripled. In 2004, an official program to address problems related to cannabis addiction was implemented. As part of this program, specific outpatient settings for cannabis use disorders were created., Objective: We present the sociodemographic characteristics, the prevalence of cannabis, alcohol and others psychoactive substances and the prevalence of mental disorders in 90 cannabis users seen at an outpatient specific setting for cannabis use disorders in the Lariboisière hospital (a university hospital in Paris)., Measures: Twelve months prevalence of substance abuse and dependence, psychiatric diagnoses based on the DSM-IV and the Mini-International Neuropsychiatric Interview (MINI) results are described., Results: The study population had the following characteristics: 67% male, mean age 27.5 (S.D.=8.4) years and 59% single or divorced. Approximately, two-thirds of the users (67%) were students or currently working and 32% were unemployed. Twenty-two percent of the cannabis users received unemployment, welfare or disability benefits and 11% declared no source of revenue. Most of the users (63%) decided on their own to seek care at the setting. Seventy-three percent of the subjects had seen a psychologist or a psychiatrist in the past, with or without relation to cannabis use. By far, most of the users were cannabis dependent (82%) and 9% cannabis abusers in the last 12 months according to DSM-IV criteria prior to their visit. Seven percent of the cannabis users had alcohol dependence and 7% were abusers. The 12 months prevalence of cocaine or ecstasy dependence was 2% and the prevalence of benzodiazepines, heroin or stimulants dependence 1%. The main substances used over lifetime were tobacco (99%); alcohol (96%); cocaine (41%); benzodiazepines and hypnotics (41%); ecstasy (40%) and heroin (23%). Four percent of cannabis users had a history of intravenous drug use. The main consumption mode of cannabis in France is the blunt. About three-quarters of the consumption is in the form of resin (hashish) and one-quarter as marijuana (grass). The average consumption of cannabis in the last six months was equivalent to 5.8 blunts per day (S.D.=4.4) and 12 g per week (S.D.=10.5), and the average monthly cost was 159 euro (S.D.=133) (234 USD, S.D.=196). The prevalence of psychiatric disorders according to DSM-IV criteria in the sample is high. A current mood disorder was present in 48% and an anxiety disorder in 55% of the cannabis users in the last 12 months. The prevalence of affective disorders in the last 12 months was major depressive disorder (38%), dysthymia (19%), hypomania (3%) and mania (1%). The prevalence of anxiety disorders in the last 12 months was social phobia (29%); generalised anxiety disorder (17%); panic disorder with or without agoraphobia (16%); obsessive compulsive disorder (12%); agoraphobia without panic disorder (9%) and post-traumatic stress disorder (5%). The prevalence of schizophrenia was 4%. The prevalence of bulimia was 4% and no anorexia. Women are more likely to report an affective disorder (64% versus 41%; p=0.04) or a post-traumatic stress disorder (17% versus 0%; p<0.001) in the last 12 months. The prevalence of family history for psychiatric disorders was 52% and for addiction, 59%., Conclusions: The cannabis users seen in our specific setting are a fairly homogeneous group and for the most part addicted to cannabis only, but with very high rates of dependence. Indeed, other than tobacco dependence, 80% of the users were only dependent on, or abused on cannabis in the last 12 months. In comparison with the cohort of French cannabis users (n=4202) seen at specific outpatient settings for marijuana users in 2005, cannabis users seen in Lariboisière Hospital are older, the percentage of females is greater, they are more dependent on marijuana and have a high prevalence of affective and anxiety disorders.

We report on a tianeptine dependence lasting for eighteen months in a 42 year old patient. The patient had a previous history of addiction to opiates, amineptine, cocaïne and alcohol. He also had a family history of addiction to alcohol and opiates. Tianeptine was prescribed for a major depressive disorder. The patient alleged a "flash sensation" like with heroin since the very first doses with a physical and psychological well-being sensation, better psychomotor performances and transient mood elation. His addiction to tianeptine was immediate and heavy. The positive reinforcement faded away after one month and a total dependance took over, with physical and psychological withdrawal symptoms when doses were not renewed. After two months of treatment, the daily consumption of tianeptine was of 90 tablets. The patient was hospitalised to treat both the addiction to tianeptine and the ongoing major depressive disorder. He was taking 240 tablets daily. In the literature, reports of addictions to antidepressants are scarce and most of them involve agents with amphetamine-like properties, including amineptine and tranylcypromine. Other reports involving other antidepressant agents, including amitriptyline, fluoxetine and tianeptine remain exceptional. Addictions to antidepressants almost exclusively concern patients with a diagnosis of personality disorder and a previous history of drug or alcohol abuse and who are treated for a depressive disorder. Tianeptine, which is devoid of any psychostimulating effect in human, does not seem to have addictive properties apart from the reports of scarce cases.

We report on the case of a 20 year old woman with no previous psychiatric history, who displayed a first episode of catatonia with acute onset. Symptoms started plainly with sudden general impairment, intense asthenia, headache, abdominal pain and confusion. After 48 hours, the patient was first admitted to an emergency unit and transferred to an internal medicine ward afterwards. She kept confused. Her behaviour was bizarre with permanent swinging of pelvis, mannerism, answers off the point and increasingly poor. The general clinical examination was normal, except for the presence of a regular tachycardia (120 bpm). The paraclinical investigations also showed normal: biology, EEG, CT Scan, lumbar puncture. Confusion persisted. The patient remained stuporous, with fixed gazing and listening-like attitudes. She managed to eat and move with the help of nurses but remained bedridden. The neurological examination showed hypokinaesia, extended hypotonia, sweating, urinary incontinence, bilateral sharp reflexes with no Babinski's sign and an inexhaustible nasoorbicular reflex. The patient was mute and contrary, actively closed her eyes, but responded occasionally to simple instructions. For short moments, she suddenly engaged in inappropriate behaviors (wandering around) while connecting back to her environment answering the telephone and talking to her parents. The patient's temperature rose twice in the first days but with no specific etiology found. During the first 8 days of hospitalization, an antipsychotic treatment was administered: haloperidol 10 mg per os daily and cyamemazine 37.5 mg i.m. daily. Despite these medications, the patient worsened and was transferred to our psychiatric unit in order to manage this catatonic picture with rapid onset for which no organic etiology was found. On admission, the patient was stuporous, immobile, unresponsive to any instruction, with catalepsy, maintenance of postures, severe negativism and refusal to eat. A first treatment by benzodiazepine (clorazepate 20 mg i.v.) did not lead to any improvement. The organic investigations were completed with cerebral MRI and the ruling out of a Wilson's disease. Convulsive therapy was then decided. It proved dramatically effective from the first attempt; 4 shocks were carried out before the patient's relatives ask for her discharge from hospital. The patient revealed she had experienced low delirium during her catatonic state. The clinical picture that followed showed retardation with anxiety. She was scared with fear both for the other patients and the nursing team. She kept distant and expressed few affects. The treatment at the time of discharge was olanzapine 10 mg per os. She was discharged with a diagnosis of catatonia but with no specific psychiatric etiological diagnosis associated. She discontinued her follow-up a few weeks later. After one year, we had no information about her. Catatonia has now become rare but remains a problem for clinicians. We reviewed data concerning short term vital prognosis and psychiatric long term prognosis in catatonia. Lethal catatonia is associated with acute onset, both marked psychomotor and neurovegetative symptoms. In the light of literature, there is no proband clinical criterion during the episode that is of relevant diagnostic value to ascertain the psychiatric etiology.

Epidemiologic studies in the general population, taking into account certain bias inherent to the clinical observation have confirmed the clinical impression reporting a higher psychiatric comorbidity with persons suffering from migraine than in persons without migraine. Persons with migraine are at increased risk for affective and anxiety disorders, personality traits disorders (neuroticism), suicide attempts, but not for alcohol or illicit drug abuse. The comorbidity is more important in migraine with aura than in migraine without aura. Concerning affective disorders, the lifetime prevalence of major depression is 34.4% in persons with migraine and 10.4% in persons without migraine. For bipolar I disorder, prevalence is 6.8% in migraine with aura versus 0.9% when no migraine. Compared to no migraine, the lifetime prevalence of anxiety disorders in migraine is significantly increased in: panic disorder (10.9% vs 1.8%); generalized anxiety disorder (10.2% vs 1.9%); obsessive-compulsive disorder (8.6% vs 1.8%); phobic disorder (39.8% vs 20.6%). In addition, no psychopathological, biological or genetic explanation seems to be meaningful for the comprehension of this comorbidity pattern. These results remain primarily descriptive but they justify a clinical investigation of affective and anxiety disorders, and suicide attempts, in all person with migraine, and it also justifies the treatment of pain associated with the treatment of eventual affective or anxiety disorders.
