Impact of COVID-19 pandemic and lockdowns on the consumption of anxiolytics, hypnotics and antidepressants according to age groups: a French nationwide study.

BACKGROUND: Previous studies have shown a negative impact of the COVID-19 pandemic and its associated sanitary measures on mental health, especially among adolescents and young adults. Such a context may raise many concerns about the COVID-19 pandemic long-term psychological effects. An analysis of administrative databases could be an alternative and complementary approach to medical interview-based epidemiological surveys to monitor the mental health of the population. We conducted a nationwide study to describe the consumption of anxiolytics, antidepressants and hypnotics during the first year of the COVID-19 pandemic, compared to the five previous years. METHODS: A historic cohort study was conducted by extracting and analysing data from the French health insurance database between 1 January 2015 and 28 February 2021. Individuals were classified into five age-based classes. Linear regression models were performed to assess the impact of the COVID-19 pandemic period on the number of drug consumers, in introducing an interaction term between time and COVID-19 period. RESULTS: Since March 2020, in all five age groups and all three drug categories studied, the number of patients reimbursed weekly has increased compared to the period from January 2015 to February 2020. The youngest the patients, the more pronounced the magnitude. CONCLUSIONS: Monitoring the consumption of psychiatric medications could be of great interest as reliable indicators are essential for planning public health strategies. A post-crisis policy including reliable monitoring of mental health must be anticipated.

[Involuntary admission to psychiatry at the request of caregivers: The point of view of caregivers]. / Les soins psychiatriques à la demande d'un tiers : le point de vue du tiers.

OBJECTIVES: In France, the family and friends of a patient with a psychiatric disorder can legally be involved in the decision to involuntary admission to psychiatry through care at the request of a third party. This involvement has been questioned in recent years, notably to protect this third party. The main objective of this work was to assess whether providing the third party with information on care without consent when providing care at the request of a third party (SDT) had an impact on the third party's experience. The secondary objectives were to identify other factors that might impact the third party's experience of the SDT, and to assess the impact of the SDT on the relationship between the third party and his or her hospitalized relative, as well as the factors that might influence it. METHODS: The study was based on a questionnaire, constructed after meeting several members of an association of relatives of patients with psychiatric disorders : UNAFAM. This questionnaire questioned the context of hospitalization, the information provided concerning care without consent, the experience of the third party at the time of hospitalization and at a distance, and the impact of hospitalization on the relationship between the third party and his or her hospitalized relative, both at the time of hospitalization and at a distance. This questionnaire was then sent to UNAFAM members in three randomly selected regions. It was specified that it was only intended for people who had already been a third party during SDT. The results were received anonymously. RESULTS: Among the 166 respondents, 85 (51.2 %) had received information about involuntary admission, and there was more frequent relief at the time of hospitalization (P<0.01) and at a distance (P<0.01), and less frequent feelings of violence towards their loved one at a distance from hospitalization (P=0.02) compared to those who had not received information. The negative impact of hospitalization on the relationship between the third party and their hospitalized relative was lower (P=0.04) among third parties who received information. The fact that the doctor was perceived as being mainly responsible for the decision to hospitalize also preserved the third party's experience and relationship with his or her relative. However, third parties who understood their involvement as an administrative necessity reported less frequent relief (P=0.01), and the negative impact of hospitalization on their relationship with their relative was higher (P=0.01). Conversely, the fact that they felt integrated into the care and listened to by the health care team was correlated with a better experience of the situation by the third party, and a lesser negative impact of hospitalization on the relationship between the third party and their relative. CONCLUSIONS: Providing information to the third party about involuntary admission at the time of an SDT could improve his or her experience of the situation and limit the negative impact of hospitalization on his or her relationship with his or her loved one. Although it seems important for the third party to feel that the majority of the decision to hospitalize is made by the physician, including him/her in this decision could improve his/her experience of the situation and limit the negative impact of hospitalization on the relationship between the third party and his/her family member.

[Suicidality in the perinatal period: Descriptive study on factors associated with suicidal ideation among women hospitalized in the perinatal period at the specialized hospital center]. / Suicidalité en période périnatale : quels sont les facteurs associés ?

OBJECTIVES: Suicide is the leading cause of maternal mortality in high-resource countries. The onset of suicidal ideation is a major risk factor for suicide attempts. Suicidality has a major impact on the mother-baby relationship and on child development. The main objective of the study was to identify factors associated with the occurrence of perinatal suicidal ideation in women requiring hospitalization. The secondary objectives of the study were to describe the socio-demographic and clinical characteristics of this specific population, to specify the follow-up procedures at hospital discharge and to develop a semi-directed interview framework for psychiatric evaluation of perinatal patients admitted to a psychiatric hospital in order to better identify those at risk of suicide and improve overall management, particularly in terms of referral to existing perinatal care services. METHODS: Descriptive and retrospective study carried out at the Specialized Hospital Center of women hospitalized in the perinatal period between 2014 and 2019. The inclusion criteria were: inpatient pregnant or postpartum within one year of delivery, 16 to 43 years. A keyword search was performed to retrieve the computerized records. All records matching the inclusion criteria were included. We studied the occurrence of suicidal ideation according to the main known clinical and socio-demographic risk factors. RESULTS: The sample included 25 pregnant patients and 57 post-partum patients. The presence of a psychiatric history increased the risk of suicidal ideation by 4.38 (P<0.03). The association between the occurrence of a stressful life event and the risk of suicidal ideation onset was close to significant (P<0.10). One third of the patients had been admitted for a reason related to suicidality. Less than one-third of the patients had been referred to existing perinatal services. CONCLUSIONS: Suicidality in the perinatal period has a major impact on the dyad as well as on the whole family. The search for suicidal ideas must be systematic during psychiatric interviews, a fortiori when a psychiatric history has been authenticated. Every patient hospitalized in adult psychiatry should be referred to specialized outpatient perinatal psychiatry services. Prevention involves raising awareness and training of all health professionals, networking, but also informing the general public.

[Treatments for depression in consultation-liaison psychiatry: From theory to practice]. / Les traitements de la dépression en psychiatrie de liaison : de la théorie à la pratique.

Treatments for depression include an adapted lifestyle, physical activity, psychotherapies, antidepressant and mood stabilizing drugs, neuromodulation, chronotherapy, spa treatments. Drug treatments used for major depressive episode are antidepressants and mood stabilizers. For a mild episode, psychotherapy is indicated. It should be combined with an antidepressant (serotonin reuptake inhibitor) for moderate and severe episodes. Suicide risk assessment is essential throughout the depressive episode. It is recommended to monitor at the start of antidepressant treatment for suicidal behavior, a change in mood suggesting an underlying bipolar disorder. The effectiveness of the treatment is evaluated after 4 to 8 weeks. The total duration of antidepressant treatment for an EDC is between 6 months and 1 year after remission, in order to prevent relapses. The use of liaison psychiatry, a real healthcare system within the general hospital, is strongly recommended for better screening and treatment of depression, thus reducing the length of hospital stays, improving the prognosis of depression. The aim of this article is to provide clinicians with a summary of validated data on the efficacy/tolerance of treatment for depression, and to suggest practical action to be taken on the main daily clinical situations: treating comorbid conditions, taking into account interactions drugs, manage the serotonin syndrome, lead to withdrawal from antidepressants, manage treatment in the elderly.

[Evaluation of the use of care programs provided for under the law of 5 July 2011]. / Évaluation du recours au programme de soins prévu par la loi du 5 juillet 2011.

OBJECTIVES: The law of 5 July 2011 introduced the possibility of outpatient care without consent in the context of care programs (CP). Despite major ethical and legal issues and frequent recourse in France, few studies are available on the use of this mechanism. An in-depth review of practices involving a large sample of CP was essential. The main objective of this study was to look at their content, the clinical profile of the patients involved, and the progress of these CP. METHODS: We carried out a retrospective, observational study, including all the CP set up between January 1st, 2016 and December 31st, 2018 in the Sarthe department. Data strictly related to the CP (content, justification, duration, patient compliance, re-hospitalizations, etc.), and patient-related variables (socio-demographic characteristics, diagnosis, antecedents, etc.) were studied. RESULTS: We studied 559 CP, 70 % of which (n=391) in the context of "care by decision of the hospital director", with a wide disparity of recourse by psychiatric sector. One third of the hospitalizations without consent ended with a CP. They involved men (68.5 %, n=383), with a psychotic disorder (77.8 %, n=435), with a history of hospitalization (90 %, n=503), and with poor adherence to care (83.2 %, n=465). Cannabis use accounted for 41.3 % (n=231) of cases. Certificates initiating CP did not have a clear justification (34.6 %, n=251) or state a goal of adherence to treatment (16.5 %, n=120). The content of the different CP was homogeneous: 65.6% of medical consultations and 47.6 % with a nurse, 100 % mentioned treatment used. Their average duration was 3.4 months. Even though the CP were followed (69.9 %, n=391), 52.8% (n=295) ended with reintegration, mainly justified by symptomatic relapse (34.8 %, n=147), and new CP were put in place almost systematically (90.6 %, n=260). However, reintegrations were shorter than first-time admissions (26 vs. 95 days). When a decision was lifted (n=174), it was based on the criteria of clinical stability (35.7 %, n=120) and compliance with the CP (27.6 %, n=93). Half of hospitalizations in "care at the decision of the State representative" ended with a CP. These CP were longer (4.5 months) and with a higher rate of reintegration (62.2 %) than for those in "care at the decision of the hospital director". There was no significant difference of CP compliance according to the mode of psychiatric care. CONCLUSIONS: Our study allows a precise vision of patients concerned by CP: men with risk factors for psychiatric dangerousness, with a severe clinical profile. It also found a high rate of re-hospitalization despite good adherence with the CP which is in line with a device allowing the work of an alliance to care and interventions at the beginning of relapse. CP have poorly personalized content and are poorly justified by psychiatrists although it is a freedom-restricting measure, highlighting the need for increased awareness amongst psychiatrists of the legal framework of their practice regarding care without consent.

[Health professionals facing the coronavirus disease 2019 (COVID-19) pandemic: What are the mental health risks?] / Les professionnels de santé face à la pandémie de la maladie à coronavirus (COVID-19) : quels risques pour leur santé mentale ?

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has caused major sanitary crisis worldwide. Half of the world has been placed in quarantine. In France, this large-scale health crisis urgently triggered the restructuring and reorganization of health service delivery to support emergency services, medical intensive care units and continuing care units. Health professionals mobilized all their resources to provide emergency aid in a general climate of uncertainty. Concerns about the mental health, psychological adjustment, and recovery of health care workers treating and caring for patients with COVID-19 are now arising. The goal of the present article is to provide up-to-date information on potential mental health risks associated with exposure of health professionals to the COVID-19 pandemic. METHODS: Authors performed a narrative review identifying relevant results in the scientific and medical literature considering previous epidemics of 2003 (SARS-CoV-1) and 2009 (H1N1) with the more recent data about the COVID-19 pandemic. We highlighted most relevant data concerning the disease characteristics, the organizational factors and personal factors that may contribute to developing psychological distress and other mental health symptoms. RESULTS: The disease characteristics of the current COVID-19 pandemic provoked a generalized climate of wariness and uncertainty, particularly among health professionals, due to a range of causes such as the rapid spread of COVID-19, the severity of symptoms it can cause in a segment of infected individuals, the lack of knowledge of the disease, and deaths among health professionals. Stress may also be caused by organizational factors, such as depletion of personal protection equipment, concerns about not being able to provide competent care if deployed to new area, concerns about rapidly changing information, lack of access to up-to-date information and communication, lack of specific drugs, the shortage of ventilators and intensive care unit beds necessary to care for the surge of critically ill patients, and significant change in their daily social and family life. Further risk factors have been identified, including feelings of being inadequately supported, concerns about health of self, fear of taking home infection to family members or others, and not having rapid access to testing through occupational health if needed, being isolated, feelings of uncertainty and social stigmatization, overwhelming workload, or insecure attachment. Additionally, we discussed positive social and organizational factors that contribute to enhance resilience in the face of the pandemic. There is a consensus in all the relevant literature that health care professionals are at an increased risk of high levels of stress, anxiety, depression, burnout, addiction and post-traumatic stress disorder, which could have long-term psychological implications. CONCLUSIONS: In the long run, this tragic health crisis should significantly enhance our understanding of the mental health risk factors among the health care professionals facing the COVID-19 pandemic. Reporting information such as this is essential to plan future prevention strategies. Protecting health care professionals is indeed an important component of public health measures to address large-scale health crisis. Thus, interventions to promote mental well-being in health care professionals exposed to COVID-19 need to be immediately implemented, and to strengthen prevention and response strategies by training health care professionals on mental help and crisis management.

[Evaluation of injunction to care practices: A study of 119 cases]. / Évaluation des pratiques de l'injonction de soins : étude sur 119 sujets.

INTRODUCTION: The injunction to care (IC) is a new compulsory treatment created by the Act of June 17, 1998. Initially, this judicial tool concerned mainly sex offenders, but then the number of overall crimes requiring an IC began to dramatically rise. The judge can order this measure only if a psychiatric expertise has concluded to its potential opportunity. Then the convict must undergo a psychiatric follow-up after having served the sentence. The creation of a court-ordered treatment is based on the premise that many offenders are affected by psychiatric disorders. For the lawmaker, the aim is to lower the risk of recidivism. PURPOSES: The main purpose of this study is to assess the convicts concerned by the IC describing their sociodemographic characteristics, psychiatric diagnostics and criminal characteristics. The second purpose is to assess the efficiency of this measure regarding re-offending and specifically legal recidivism. METHODS: This is a retrospective and descriptive study concerning 119 subjects followed-up by two "coordinating doctors" in the department of Sarthe who could assess their psychiatric diagnostics and sociodemographic characteristics. They could also compare medical data with the judicial data for 78 of the subjects. RESULTS: The population was composed of 117 men (98.3%) aged 45 years old on average. They had a job in 37% of cases (n=44) and were single in 56.3% of cases (n=67). According to the DSM-IV-TR, only 29 subjects (24.4%) had an axis I disorder and 37.8% of the population had a pathological personality trait (non DSM-IV-TR categorized disorder). Furthermore, 51.3% (n=61) of the subjects were addicted (mainly alcohol). The medical follow-up was carried out by a psychiatrist in 83.2% of cases (n=99). The average duration of follow-up was five years. Among the 78 subjects for whom there was access to juridical data, 13 (16.7%) had committed a new offense during follow-up. Among them, seven had recidivated six of whom were initially sentenced for sexual offense. CONCLUSIONS: Most of the subjects in injunction to care had no axis I disorder but addictions and/or pathological personality traits. Nevertheless, the expert concluded the need of an IC. Personality and behavior disorders do not always require psychiatric care, and the management must be multidisciplinary. In France, the psychiatrist remains at the center of injunction to care measure. The addictology care is not developed whereas it is a population at risk and there is a lack of interactions between professionals (medical, social and judicial professionals). The IC is a measure that needs to be improved by means of better communication among the different professionals and a better global assessment of the subjects. Medical care must be a possible option but not a systematic treatment.

Genetic modulation of the response bias towards facial displays of anger and happiness.

BACKGROUND: Investigating genetic modulation of emotion processing may contribute to the understanding of heritable mechanisms of emotional disorders. The aim of the present study was to test the effects of catechol-O-methyltransferase (COMT) val158met and serotonin-transporter-linked promoter region (5-HTTLPR) polymorphisms on facial emotion processing in healthy individuals. METHODS: Two hundred and seventy five (167 female) participants were asked to complete a computerized facial affect recognition task, which involved four experimental conditions, each containing one type of emotional face (fearful, angry, sad or happy) intermixed with neutral faces. Participants were asked to indicate whether the face displayed an emotion or was neutral. The COMT-val158met and 5-HTTLPR polymorphisms were genotyped. RESULTS: Met homozygotes (COMT) showed a stronger bias to perceive neutral faces as expressions of anger, compared with val homozygotes. However, the S-homozygotes (5-HTTLPR) showed a reduced bias to perceive neutral faces as expressions of happiness, compared to L-homozygotes. No interaction between 5-HTTLPR and COMT was found. CONCLUSIONS: These results add to the knowledge of individual differences in social cognition that are modulated via serotonergic and dopaminergic systems. This potentially could contribute to the understanding of the mechanisms of susceptibility to emotional disorders.

Resting-state cerebral blood flow in amygdala is modulated by sex and serotonin transporter genotype.

Serotonin transporter-linked polymorphic region (5-HTTLPR) has been associated with modulation of resting-state amygdala level, which was considered to underlie a risk for mood and anxiety disorders. The findings however have been inconsistent which could be related to interactions of the genotype with other factors e.g. sex or personality characteristics. Therefore, the aim of the present study was to explore the modulation of the amygdala perfusion in the resting-state by sex and 5-HTTLPR/rs25531 genotype, controlled for personality dimensions assessed by Temperament and Character Inventory (Cloninger et al., 1994). The resting-state cerebral blood flow (rCBF) was examined using an arterial spin labelling technique. All participants were genotyped for the 5-HTTLPR/rs25531 genotype (L/L-L/S-S/S genotypes and LA-LG variants). The study group comprised 81 right-handed Caucasian healthy volunteers (42 females) aged 19-55 years. We measured rCBF in the amygdala and in the whole-brain grey matter. The data of blood-oxygen-level-dependent (BOLD) response in amygdala to fearful dynamic faces in the same sample were also analysed. There was a significant main effect of sex in both the left and right amygdalae, with higher rCBF in males. Main effect of 5-HTTLPR/rs25531 genotype which was significant in the right amygdala only, was accounted for by higher rCBF in S/S vs. L/L homozygotes. An interaction between sex and 5-HTTLPR/rs25531 genotype was observed in rCBF in the right amygdala. This was accounted for by higher values of rCBF in the right amygdala in males' S allele carriers compared with females. In females, there was a significant negative correlation between the rCBF and BOLD response in the right amygdala, and more so in S carriers. In males, there was no significant correlation between rCBF and BOLD response in the right amygdala. The novelty of our results lies in the demonstration of gene by sex interaction with resting blood flow in the amygdala that elucidates sex-related differences in emotional reactivity.

Genetic modulation of neural response during working memory in healthy individuals: interaction of glucocorticoid receptor and dopaminergic genes.

Suboptimal performance in working memory (WM) tasks and inefficient prefrontal cortex functioning are related to dysregulation of dopaminergic (DA) and hypothalamic-pituitary-adrenal systems. The aim of the present study was to investigate the joint effect of genetic polymorphisms coding for DA catabolism and glucocorticoid receptor (GR, NR3C1) on brain functioning. The study group (90 right-handed white Caucasian healthy individuals) underwent functional magnetic resonance imaging experiments to examine blood oxygenation level dependent (BOLD) response during a WM task with varying cognitive load (1-, 2- and 3-back). We have also examined skin conductance response (SCR) during the WM task and resting-state cerebral blood flow with continuous arterial spin labelling. The genetic markers of interest included Catechol-O-Methyl-Transferase (COMT) (Met(158)Val) and NR3C1 single-nucleotide polymorphisms (BclI C/G rs41423247, 9ß A/G rs6198 and rs1866388 A/G). Haplotype-based analyses showed (i) a significant effect of COMT polymorphism on left anterior cingulate cortex, with greater deactivation in Met carriers than in Val/Val homozygotes; (ii) a significant effect of BclI polymorphism on right dorsolateral prefrontal cortex (DLPFC), with greater activation in G/G carriers than in C carriers and (iii) an interactive effect of BclI (G/G) and COMT (Met/Met) polymorphisms, which was associated with greater activation in right DLPFC. These effects remained significant after controlling for whole-brain resting-state blood flow. SCR amplitude was positively correlated with right DLPFC activation during WM. This study demonstrated that GR and COMT markers exert their separate, as well as interactive, effects on DLPFC function. Epistasis of COMT and BclI minor alleles is associated with higher activation, suggesting lower efficiency, of DLPFC during WM.

Gender differences in the sensitivity to negative stimuli: cross-modal affective priming study.

BACKGROUND: There is evidence showing that men and women differ with regard to the processing of emotional information. However, the mechanisms behind these differences are not fully understood. METHOD: The sample comprised of 275 (167 female) right-handed, healthy participants, recruited from the community. We employed a customized affective priming task, which consisted of three subtests, differing in the modality of the prime (face, written word, and sound). The targets were always written words of either positive or negative valence. The priming effect was measured as reaction time facilitation in conditions where both prime and target were emotional (of the same positive or negative valence) compared with conditions where the emotional targets were preceded by neutral primes. RESULTS: The priming effect was observed across all three modalities, with an interaction of gender by valence: the priming effect in the emotionally negative condition in male participants was stronger compared with females. This was accounted for by the differential priming effect within the female group where priming was significantly smaller in the emotionally negative conditions compared with the positive conditions. The male participants revealed a comparable priming effect across both the emotionally negative and positive conditions. CONCLUSION: Reduced priming in negative conditions in women may reflect interference processes due to greater sensitivity to negative valence of stimuli. This in turn could underlie the gender-related differences in susceptibility to emotional disorders.

[Homicide and acute cortico-induced psychosis: A case report]. / Homicide et épisode psychotique aigu cortico-induit : à propos d'un cas.

BACKGROUND: Since their commercialization in 1950, the first psychiatric side effects of steroids have been reported. Today, steroids have become an important therapeutic tool in many diseases, but pharmacological mechanisms responsible for their side effects are still little known. The neuropsychiatric side effects concern 15% of patients while severe reactions occur in 5% of cases, mostly as acute psychotic episodes such as delusion. Serious forensic risks in this context are poorly documented and underestimated. CASE REPORT: We report the case of a 77 year-old man, treated by methylprednisolone for chronic lymphoid leukemia. After two months of treatment, although stabilized for the neoplastic disease, he stabbed his wife to death with a knife. In the emergency unit, an acute delirious state, a disorganization syndrome, and confusion items such as amnesia, disorientation and symptomatology fluctuation were observed. Mr. M also presented with hyponatremia and infectious pneumonia. Steroids were stopped and his condition rapidly declined, he died one month later during the hospitalization. DISCUSSION: This clinical case underlines the importance of the early detection of steroid psychosis and its management. Treatment should not be stopped brutally and a dose reducing strategy should be applied in combination with a mood stabilizer or antipsychotic treatment. Disease management strategies are insufficiently documented to be recommended. The extremely acute onset of the symptoms, a partial insight into delusions, a history of iatrogenic neuropsychiatry, the existence of somatic precipitating disorders and confusion factors should always alert the practitioner. The patient, and eventually his family circle, must be aware of the risks of adverse psychiatric effects of steroids for both ethical and forensic reasons, and must report them as early as possible to the clinician if they occur.

Interaction of catechol O-methyltransferase and serotonin transporter genes modulates effective connectivity in a facial emotion-processing circuitry.

Imaging genetic studies showed exaggerated blood oxygenation level-dependent response in limbic structures in carriers of low activity alleles of serotonin transporter-linked promoter region (5-HTTLPR) as well as catechol O-methyltransferase (COMT) genes. This was suggested to underlie the vulnerability to mood disorders. To better understand the mechanisms of vulnerability, it is important to investigate the genetic modulation of frontal-limbic connectivity that underlies emotional regulation and control. In this study, we have examined the interaction of 5-HTTLPR and COMT genetic markers on effective connectivity within neural circuitry for emotional facial expressions. A total of 91 healthy Caucasian adults underwent functional magnetic resonance imaging experiments with a task presenting dynamic emotional facial expressions of fear, sadness, happiness and anger. The effective connectivity within the facial processing circuitry was assessed with Granger causality method. We have demonstrated that in fear processing condition, an interaction between 5-HTTLPR (S) and COMT (met) low activity alleles was associated with reduced reciprocal connectivity within the circuitry including bilateral fusiform/inferior occipital regions, right superior temporal gyrus/superior temporal sulcus, bilateral inferior/middle prefrontal cortex and right amygdala. We suggest that the epistatic effect of reduced effective connectivity may underlie an inefficient emotion regulation that places these individuals at greater risk for depressive disorders.

Homicide and associated steroid acute psychosis: a case report.

We report the case of an old man treated with methylprednisolone for chronic lymphoid leukemia. After two months of treatment, he declared an acute steroid psychosis and beat his wife to death. Steroids were stopped and the psychotic symptoms subsided, but his condition declined very quickly. The clinical course was complicated by a major depressive disorder with suicidal ideas, due to the steroid stoppage, the leukemia progressed, and by a sudden onset of a fatal pulmonary embolism. This clinical case highlights the importance of early detection of steroid psychosis and proposes, should treatment not be stopped, a strategy of dose reduction combined with a mood stabilizer or antipsychotic treatment. In addition have been revised the risks of the adverse psychiatric effects of steroids.

[Homicide and major mental disorder: what are the social, clinical, and forensic differences between murderers with a major mental disorder and murderers without any mental disorder?]. / Homicide et maladie mentale grave: quelles sont les différences sociodémographiques, cliniques et criminologiques entre des meurtriers malades mentaux graves et ceux indemnes de troubles psychiatriques?

OBJECTIVES: To establish the social, clinical, and forensic differences between murderers suffering from a major mental disorder and murderers without any psychiatric disorder and, in particular, to compare their respective records of psychiatric symptoms and their respective relationship with their victims. METHOD: We studied 210 forensic examinations of murderers, the offences related to the murders, and the social and clinical information collected from psychiatric court reports on persons convicted of homicide. Firstly, we identified the socio-demographic, clinical and criminological profiles of 210 murderers from which were distinguished murderers with major mental disorder. Then, we compared the profiles of murderers suffering from a major mental disorder with those of murderers without any mental disease. In other words, we compared 37 persons affected with major mental disorder (schizophrenia, paranoiac delusional disorder, and affective disorder) with 73 persons without any mental disorder. We deliberately excluded subjects with personality disorder or abuse of/dependency on drugs, mental retardation or dementia. RESULTS: With the exception of certain variables, murderers with major mental disorder have the same characteristics as others murderers: young man, living alone, with psychiatric and offence records and substance abuse. Murderers with major mental disorder are older (37.8 versus 31.7 years old) than perpretators without any mental disorder, and the former have a psychiatric record more often than the latter (81 versus 32.9%). In addition, contrary to the latter, the former show clinical symptoms of a psychopathological process. Depression, delusional and suicidal ideas are frequent among murderers with a major mental disorder, whereas the persons without mental disorder quarrel or have a row with their victim just before their crime. The victim was known to the perpetrator significantly more often in the major mental disorder group than in the no mental disorder group (94,6 versus 76,7%, p=0,008). The most major mental disorders' homicide was more likely to be against intimates than strangers. The application of the former article 64 or the present article 122-1 of the French Criminal Code are envisaged more often in the major mental disorder group than in the no mental disorder group. CONCLUSION: The main difference between murderers with a major mental disorder and murderers without any mental disorder is the psychopathology of the morbid process which underlies the homicide. Impairment of judgment at the time of the crime should be taken into account. As a clinician, we should focus our attention on general risk factors of violence and homicide (male, young, underprivileged class, abuse of alcohol) and on more specific factors (mental disorder co-morbidities...). To these factors should be added the dynamic characteristics of the meeting of the protagonists.

Metabolic complications of bypass surgery for morbid obesity.

Postoperative complications resulting from bariatric surgery can lead to severe vitamin-deficiency states. A patient who underwent bariatric bypass surgery and later developed Wernicke's encephalopathy prompted us to present her interesting case history for discussion. Although bariatric surgery is known to be a risk factor for Wernicke's encephalopathy, this diagnosis is only rarely evoked in the postoperative course. We recommend that the occurrence of digestive, psychiatric or neurological symptoms after bariatric surgery should suggest a thiamine deficiency that must be promptly assessed. Without waiting for the results, thiamine supplementation should be initiated.

[Homicide and psychosis: criminological particularities of schizophrenics, paranoiacs and melancholic. A review of 27 expertises]. / Homicide et psychose: particularités criminologiques des schizophrènes, des paranoïaques et des mélancoliques. A propos de 27 expertises.

INTRODUCTION: During the night of the 11 to 12 of December 2002, Mathieu X. 21 years old, convinced he was defending himself from evil human beings decapitated a nurse and an auxiliary nurse of the psychiatrist hospital. This crime, which received saturated media coverage, obviously raises questions about the dangerous and violent nature of the mentally ill, which can sometimes culminate in homicide. Firmly rooted in the collective consciousness is the popular idea that someone who kills an unknown person in the street is mentally ill. Conversely, the epidemiological data are reassuring; only 15% of such crimes are committed by the seriously mentally ill (schizophrenia, paranoia, melancholia). AIM: Typing and comparison of homicides committed by schizophrenic, paranoiac and melancholic persons. METHOD: Several murders committed by psychotic persons are presented in this article. This retrospective study shows several types of pathological murder (schizophrenia, paranoiac delirious disorder, affective disorder: melancholia and hypomania). Twenty-seven cases have been selected and analysed from 268 cases prepared over 30 years by two psychiatrists, whose diagnoses were schizophrenia, paranoia, melancholia or hypomania. RESULTS: From these 268 cases of homicide examined, 27 murderers were psychotic. Ten of these were young, single, jobless, male schizophrenics: they drank little alcohol. Most of them had a criminal history. They were paranoid schizophrenics whose hallucinatory mechanisms fed mostly persecuted, sexual and metaphysical themes. Forty percent of them were disorganised, and half of them showed negative features. They knew their victim (family, friends). Nine others were paranoiac, for the most part male, older, married, family men, without psychiatric or criminal record. Intuitions with delirious fed persecuted (77%), jealous (40%) or prejudicial themes. They murdered their wife or husband or neighbour. Alcohol consumption was often involved. Schizophrenic and paranoiac murderers often have an emotional temper. Conversely, melancholic murderers are mostly female aged around 30, married, family women, drinking little alcohol. Two-thirds of them have psychiatric records of depression, bipolar disorders and attempted suicide. Altruism is the most frequent delirious theme. Their murders are more often premeditated. They know the victim: child or partner. Suicide often follows the murder.

Cognitive changes in asymptomatic carriers of the Huntington disease mutation gene.

Huntington disease (HD) is a neurodegenerative disorder due to an excessive number of CAG repeats in the IT15 gene on chromosome 4. Studies of cognitive function in asymptomatic gene carriers have yielded contradictory results. This study compared cognitive performance in 44 subjects with the HD mutation (group of carriers) who had no clinical signs of HD and 39 at-risk individuals without HD mutation (group of non-carriers). Neuropsychological evaluation focused on global cognitive efficiency, psychomotor speed, attentional, executive and memory functions. Significant differences, with lower performances in the group of gene carriers, were detected for some measures of psychomotor speed, attention and executive functioning (all P < 0.01). More differences between groups were observed for memory measures, in particular on the California Verbal Memory Test. Complementing these observations, cognitive scores were correlated with age in the group of gene carriers, but not in the group of non-carriers. This suggests that the cognitive changes precede the appearance of the motor and psychiatric symptoms in HD and that tests proved to be sensitive to early HD deficiencies are better suited than global cognitive efficiency scales to observe them.

[Exposure to psychosocial stressors at work in the Pays de la Loire region in 2002]. / Exposition au stress psychosocial chez les salariés des Pays de la Loire en 2002.

OBJECTIVE: An epidemiological surveillance system of work-related musculoskeletal disorders of the upper limb (MSDs) was implemented in 2002 in the Pays de la Loire region to assess the prevalence of the MSDs and their biomechanical and psychosocial risk factors in the working population. We will report here only the results concerning the exposure to psychosocial stress in the work environment. According to the Karasek "demand-autonomy" model, high psychological work demands may increase risk of ill health, particularly if there is a low level of decision latitude for the employees and low social support by the hierarchy or colleagues. METHODS: In 2002, 68 out a total of 400 occupational physicians volunteered to participate in the surveillance program and included 1 495 workers (895 men, 600 women) representative of the region's workforce. Work history and work environment were assessed by a self-administered questionnaire before the compulsory annual visit of occupational physicians. Exposure to psychosocial stress at work was assessed with the Job Content Questionnaire (JCQ) developed by Karasek. The three scales of decision latitude, social support and psychological demands were calculated using Karasek's recommendations. RESULTS: The mean scores of psychological demands, decision latitude and social support were 69.3 +/- 12.7; 22.3 +/- 3.2; 24.0 +/- 3.5, respectively. No differences were observed according to gender and age. A third of the workers were exposed to high psychological demands at work and most of them (61%) had little decision latitude to cope with work constraints. About 28% of workers suffered from a lack of social support from their colleagues or supervisors. Overall, about 17% of workers were exposed to a situation of "Job strain" (ie a combination of a high level of psychological demands and a low level of decision latitude) and 7% were exposed to a situation of "Job strain" with social isolation ("Job strain" with low social support). The situations of "Job strain", associated or not with a low level of social support, were particularly frequent in industries with taylorized work organisation, like the food industry and automobile industry, and in services characterised by strong merchant constrains, such as trade and cleaning services, for example. The frequency of "Job strain", with or without social isolation, was almost double in temporary workers. DISCUSSION: This study confirms that in a representative sample of workers, the exposure to occupational stress is not limited to managers and professionals, but concerns also a large number of employees and blue-collar workers of the public and private sectors. In general, the strongly qualified occupations are characterised by a high level of psychological demands, but individuals have large decision latitude to cope, which allows them to develop their capacities. The less qualified occupations are generally less confronted with a high level of mental demands than the managers and professionals. However, these individuals do not have enough decision latitude to cope with psychological demands which could lead to a high level of "Job strain", notably in the case of lack of social support from the supervisors and the colleagues. CONCLUSION: The study shows that the exposure to occupational stress is not limited to managers and professionals, but also concerns numerous employees and blue-collar workers. The determinants of work strain differ depending on occupations and this should be taken into consideration when implementing prevention programs for stress at work.
