Abstract
OBJECTIVES We determined the prevalence of controlled prescription drug (CPD) non-medical and lifetime use and their predictors among patients at three public psychiatric clinics in Uganda to identify missed care opportunities, enhanced screening priorities, and drug control needs. METHODS A cross-sectional survey of 1275 patients was performed from November to December 2018. Interviewer-administered semi-structured questionnaires, desk review guide and urine drug assays were employed. Questionnaire recorded CPD non-medical and illicit drug use history from patients' files, CPD lifetime use and risk factors. Desk review guide recorded recently prescribed drugs in patients' files to corroborate with urine assays. Predictors were analysed by multivariate logistic regression. RESULTS From desk review, 145 (11.4%) patients had history of CPD non-medical use and 36 (2.8%) had used illicit drugs. Of 988 patients who provided urine, 166 (16.8%) self-medicated CPDs, particularly benzodiazepines while 12 (1.2%) used illicit drugs. Of those with drug-positive urine, 123 (69.1%) had no documented history of CPD non-medical and illicit drug use. Being an inpatient (OR=10.90, p<0.001) was independently associated with CPD non-medical use. Additionally, being an inpatient (OR=8.29, p<0.001) and tobacco consumption (OR=1.85, p=0.041) were associated with CPD non-medical and illicit drug use combined. Among participants, 119 (9.3%) reported CPD lifetime use, and this was independently associated with education level (OR=2.71, p<0.001) and history of treatment for substance abuse (OR=2.08, p=0.018). CONCLUSIONS CPD non-medical use is common among Uganda's psychiatric patients, and more prevalent than illicit drug use. Rapid diagnostic assays may be needed in psychiatric care in resource limited settings. It is necessary to assess how CPD non-medical use impacts mental care outcomes and patient safety. High risk groups like inpatients and tobacco consumers should be prioritised in psychiatric screening.

Benzodiazepine abuse, misuse, dependence, and withdrawal among schizophrenic patients: A review of the literature. Psychiatry Res 2020; 284:112660.

Abstract
Patients diagnosed with schizophrenia are at least three times more likely to develop a substance use disorder than controls. These patients are frequently prescribed benzodiacepines as a coadjuvant drug, which have a high potential for addiction. We performed a literature review aiming to gather evidence on various topics concerning the use of benzodiacepines in schizophrenia, with a focus on possible abuse: 1) Prevalence of prescripted and non-prescripted benzodiacepine use among patients, 2) Prevalence of abusers, 3) Effects of long-term benzodiacepine abuse in schizophrenia prognosis, 4) Possible management strategies for benzodiacepine abuse in this population. Our search revealed there is a high variability (up to 20%) in benzodiacepine abuse among patients, with cannabis and stimulants being more frequent, and no clear demographic traits have been identified among these patients. Patients with affective symptoms are more likely to abuse benzodiazepines. Its long-term effects on prognosis have been debated, with some papers hinting at a higher mortality rate. Tapering benzodiacepines has been associated with an improvement in some cognitive functions. Management strategies for potential abuse do not differ greatly for this population, and no specific pharmacological aid can be indicated, but an integral approach is proposed.

Abstract
AIMS The aim of this cross-sectional study was to examine the prevalence of psychological dependence on benzodiazepines in outpatients with panic disorder and elucidate demographic and clinical characteristics associated with this condition. METHODS Subjects were eligible if they were outpatients in four clinics in Tokyo, Japan, aged 18 years or older and met the diagnostic criteria for panic disorder according to the ICD-10. The subjects received the following assessments: the Severity of Dependence Scale, Japanese Version (SDS), the Self-Report Version of Panic Disorder Severity Scale, Japanese Version (PDSS-SR), and the Quick Inventory of Depressive Symptomatology-Self Report, Japanese Version. The following information was also collected: age, sex, ethnicity, duration of illness, physical and psychiatric comorbidities, and details of prescribed psychotropic medications. RESULTS The data from 51 outpatients showed that 31 patients (60.8%) showed psychological dependence (i.e. a total score of ≥5 in the SDS). The proportion of patients with dependence was significantly lower in remitted patients (i.e. a total score of ≤4 in the PDSS) (44.1%, n = 15/34) than those who were not (94.1%, n = 16/17) (Pearson χ(2) = 11.9, P < 0.001). A multiple regression analysis showed that the PDSS scores showed a positive correlation with the SDS total scores (β = 0.60, 95% confidence interval = 0.30-0.90, P = 0.0001). CONCLUSION These findings emphasize the need for enhanced awareness about benzodiazepine dependence in patients and psychiatrists, as well as especially close attention to patients with panic disorder who present severe symptomatology.

Abstract
OBJECTIVE Although the addictive potential of benzodiazepine drugs has been known for a long time, new cases of benzodiazepine addictions keep emerging in clinical practice. The etiology of benzodiazepine addiction seems to be multifactorial. The objective of this study was to investigate and measure psychological and situational factors differentiating benzodiazepine addicts from not addicted users. METHODS A psychological profile and situational factors of patients with the diagnosis of benzodiazepine addiction and a carefully matched control group of not addicted former benzodiazepine users were defined and investigated. RESULTS The investigated benzodiazepine addicts differed significantly from the control group in particular psychological dimensions, such as higher neuroticism and introversion, prevalence of emotional rather than task based coping mechanisms. There were also significant correlations between the addiction and situational factors such as BZD - treatment circumstances and adverse life events previous to the treatment. CONCLUSIONS The results show psychological and situational factors which differentiate benzodiazepine addicts from not addicted benzodiazepine users. This data suggest that benzodiazepine addiction might be associated with higher neuroticism, introversion and less effective coping mechanisms as well as with previous accumulation of adverse life events and/or inadequate BZD treatment. The psychological and situational factors mentioned above might be considered as potential risk factors for benzodiazepine addiction.

Abstract
Anxiety disorders during pregnancy are highly prevalent and associated with serious and enduring consequences for both mother and child. Exposure-based cognitive behavioral (CBT) and behavioral therapies (BT) represent the most empirically supported psychosocial treatments for anxiety disorders in general adult samples. Pregnant women, however, generally have been excluded from this body of research. Evidence that pregnant women inhabit a unique biological context combined with untested assumptions that exposure would unduly stress or harm the fetus have likely prohibited inquiry. This paper seeks to remedy this gap by integrating findings from obstetric, psychiatric, and psychological research to inform central questions regarding exposure-based treatment of anxiety disorders during pregnancy. Based on available evidence, we consider the potential risks and benefits of CBT/BT for anxiety disorders during pregnancy relative to other currently available treatment options. From a multidisciplinary research perspective, we argue that exposure-based therapies are likely to be safe during pregnancy, particularly relative to the alternatives. However, we also highlight critical questions for future research to directly test the biopsychological impact of exposure-based therapies among pregnant women.

Abstract
BACKGROUND There are hardly any studies carried out in Pakistan on the usage of benzodiazepines at the level of community. This research was aimed to determine the frequency of benzodiazepine use, along with its associations with socio-demographic and clinical characteristics among community dwelling adults, residing in two urban settlements of Karachi, Pakistan. METHODS We performed a cross sectional study from August 2008 to December 2009, in 2 areas of Karachi, namely Garden and Sultanabad. We followed the systematic sampling strategy to randomly select the households, with an adult of either sex and of age 18 years or more. Data collection was carried out through interview, using a pre-tested questionnaire, with items on socio-demographic position, medical history and benzodiazepine use. Student's t-test and χ2 test was employed to determine the associations between socio-demographic and clinical characteristics, and their relationship with benzodiazepine use was determined using applied logistic regression. RESULTS The overall percentage of benzodiazepine consumption was estimated to be 14%. There were significantly more benzodiazepine users in the peri-urban Sultanabad community to the urban community of Garden (p-value = 0.001). The mean age (± SD) for users was 51.3 (± 15.6) years compared to 37.1 (± 14.4) years among non-users. Bromazepam was the most widely used benzodiazepine (29%); followed by diazepam, with a median duration on primary use being 144 weeks (IQR = 48-240). The adjusted logistic regression model revealed that increasing age, location, female sex, unemployment and psychiatric consultation were associated with increased likelihood of benzodiazepine use. CONCLUSION We believe the unregulated over-the-counter sales of benzodiazepines and social conditions might be playing a role in this high consumption of benzodiazepines in the community.

Abstract
AIn this work, the authors have analysed the principal studies on the interest in the use of benzodiazepines in schizophrenia. The first double-controlled study concerning this question was conducted in 1961. The results of the first studies are criticisable due to the variability of the diagnostic and clinical assessment criteria, as well as to the divergences between the different conclusions. Through this review of literature, the authors wish to clarify the questions and hypothesis raised specify certain therapeutic strategies. MECHANISM OF GABA-ERGIC TREATMENTS: The analysis of the principle works on this question provides evidence on the use of benzodiazepines in schizophrenia. By fixing on their receptors, benzodiazepines facilitate GABA-ergic transmission. GABA is an inhibitor neurotransmitter. The GABA stimulation induced by benzodiazepines may be at the origin of a reduction of the pre-synaptic release of dopamine in the mesolimbic region. The GABA stimulation may also delay the post-synaptic adaptation of the dopaminergic neurons to neuroleptics. This phenomenon may enhance the activity of neuroleptics in resistant schizophrenia. Benzodiazepines would also have an effect on the mesoprefrontocortical regions where neuroleptics may be less efficient. It is interesting to note that this cerebral region is particularly sensitive to stress. This effect of benzodiazepines on the mesoprefrontocortical region might explain a preferentially beneficial effect in patients who have radiographic signs consistent with prefroncortical atrophy, although this observation remains preliminary. BENZODIAZEPINES IN MONOTHERAPY: In monotherapy their action on productive and deficient psychotic symptoms is greatly discussed and not very convincing. The main studies in the use of benzodiazepines alone ) are heterogeneous for their diagnosis criteria, their methodology and their results. The conclusions of the publications are not totally clear, and different points are to be criticized: heterogeneity of assessment criteria, heterogeneity and variability of methodology, use of non standardized scales, most of the studies are open studies, variability of benzodiazepines dose. BENZODIAZEPINES IN ASSOCIATION WITH NEUROLEPTICS: In few controlled studies, most authors have underlined ) the advantage of the association of benzodiazepines with neuroleptics. This association may act either on positive symptoms (hallucinations, delusions) or on negative symptoms. The latent period and the length of the effect of benzodiazepines in the treatment of psychotic patients remain unclear. According to certain studies, the therapeutic effect may appear in a short time, and then disappear within the fourth week. The association of benzodiazepines with neuroleptics is particularly helpful for patients with great anxiety, whether they have neuroleptic intolerance or not. There is no robust convergence about the type of benzodiazepines and their optimal dose in the treatment of schizophrenia. Their use may permit a reduction in the neuroleptic dose. They could increase the plasma concentration of neuroleptics and they might act on the mesoprefrontocortical regions where there are fewer dopaminergic auto receptors. BENZODIAZEPINES AND ANXIETY IN SCHIZOPHRENIA: States of anxiety, and in particular panic disorders that would participate in the exacerbation of psychotic symptoms, would benefit from the use of benzodiazepines. Anxiety can be considered as a major symptom of schizophrenia: insecure feelings and impressions of threatening events are frequent during schizophrenia. Interpretations or brutal hallucinations can lead to the feeling of imminent catastrophe or anxiety. Nevertheless, anxious phenomenons are under-estimated for many reasons: on the one hand, positive symptoms may hide anxiety, and on the other, the symptoms that are observed in patients treated with neuroleptics are often attributed to the neuroleptic side effects rather than linked to anxiety. Benzodiazepines and catatonia - Lorazepam has demonstrated its efficacy on catatonia. This effect seems to be specific of small doses of lorazepam (<5 mg/day). It should be compared to the effect of zolpidem in the same conditions. This prescription should be limited to acute catatonia, with no effect on chronic catatonia. Benzodiazepines and neuroleptic side effects - The use of benzodiazepines to treat some side effects of neuroleptics such as akathesia is reported by certain authors but remains little explained. They may have no effect or only small effects on tardive dyskinesia, but could reduce their incidence with the use of the smallest doses of neuroleptics in association with benzodiazepines. Safety of use - The safety of use of benzodiazepines in schizophrenia, particularly in association with neuroleptics is admitted, however recommended precautions with clozapine are to be noted. Benzodiazepine combined with clozapine clearly increases the frequency of cardiovascular and respiratory accidents. Some studies point out the risk of behavioural desinhibition and dysphoria. Their use should also be limited to patients with good compliancy, in order to avoid exacerbation of symptoms in the case of brutal interruption of the treatment. Dependency, which is an important issue in the use of benzodiazepines, seems much lesser in schizophrenia than in personality disorders and anxiety. Conversely, some studies point out the benefits of benzodiazepine use in schizophrenia, with their efficacy in the treatment and prevention of drug abuse. Finally, benzodiazepines contribute to the establishment of a good patient-doctor relationship, and may guarantee enhanced treatment compliancy.

Abstract
Relatively little is known about the prevalence and clinical characteristics of dependence on sedative-hypnotics, and almost nothing has been published regarding abuse. This report relates information on Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-IIIR) sedative-hypnotic use disorders among subjects from the Collaborative Study on the Genetics of Alcoholism (COGA). A standardized interview was used to generate data on 407 men and women in Group 1 with sedative-hypnotic dependence (4.4% of the COGA sample), 34 in Group 2 with abuse (0.4%), and 3,426 comparison subjects in Group 3 with alcohol dependence in the absence of a sedative-hypnotic use disorder (36.7%). The remaining COGA subjects (48.5%) were not included as they had neither alcohol nor sedative-hypnotic dependence or abuse. Those with sedative-hypnotic abuse or dependence were more likely to be Caucasian individuals with abuse or dependence on marijuana, cocaine, amphetamines, or opioids. Subjects in Groups 1 and 2 were also more likely to have histories of independent major depressive and panic disorders, as well as substance-induced mood disorders. Those with dependence, compared to abuse, were likely to be women, reported staying intoxicated for a day or more, but noted less abuse of opioids or amphetamines, although Group 2 members also had high rates of difficulties with sedative-hypnotics. These results highlight notable rates of sedative-hypnotic dependence in the COGA families, and indicate that while sedative-hypnotic abuse does occur, and while the clinical course can involve relatively serious problems, it is less common than dependence.

Abstract
This objectives of this study were three-fold: retrospectively evaluate anxiolytic/hypnotic consumption by psychiatric inpatients, identify the risk factors of prolonged intakes, and prospectively measure the impact of hospitalisation on the use of those drugs. Three hundred and seventy-six patients hospitalised in 11 psychiatric departments in the Paris region were studied using a structured interview for the anxiolytic/hypnotic treatments, DSM-III-R criteria, GHQ-12, HAD, Spiegel's questionnaire, COVI's anxiety scale and the CGI. Eighty-five per cent of the patients had taken one anxiolytic/hypnotic or more in the 3 months preceding hospitalisation. Hospitalisation induced little change in anxiolytic/hypnotic use: dosage frequency increased from 77% to 84% between the week preceding hospitalisation and that preceding discharge; 26% of consumers were taking at least two anxiolytics or two hypnotics in the first period vs. 23% in the second. The absence of withdrawal during hospitalisation was related to the high age and a diagnosis of depression rather than schizophrenia, to the existence of continuous intake over the 3 months preceding hospitalisation and to higher drug doses during the 7 days preceding hospitalisation. Prescription of treatment at the end of hospitalisation in previously non-user subjects was related to a higher HAD anxiety score at discharge.

Abstract
Despite the fact that there have been many reports on benzodiazepine (BZD) dependence, consensus about its definition has not been reached. Reliable prevalence data to estimate the dependence liability of BZDs are therefore lacking. This study is the first to assess the prevalence of BZD dependence in out-patient BZD users (115-general practice (GP) patients, 124 psychiatric out-patients and 33 self-help patients) on the basis of the DSM-III-R and ICD-10 substance dependence criteria. Past year and lifetime diagnoses of BZD dependence were made by means of the Schedules for Clinical Assessments in Neuropsychiatry (SCAN). High prevalence figures were found, ranging from 40% in the GP patients (DSM-III-R past year) to 97% in the self-help patients (ICD-10 lifetime), indicating that BZD users run a high risk of developing BZD dependence. The clinical management of BZD use could benefit from further development of diagnostic instruments such as a self-report questionnaire which reflects the severity of BZD dependence.

Abstract
This study aimed to evaluate the concurrent and lifetime psychiatric comorbidity and drug use patterns in patients admitted to the hospital for detoxification from benzodiazepines. Psychiatric assessments using the Structured Clinical Interview for DSM-III-R with a psychosis screening module (SCID-P and II) were conducted in 30 inpatients admitted to the medical unit treatment unit of the Clinical Research and Treatment Institute of the Addiction Research Foundation for the treatment of severe benzodiazepine dependence. Patients (mean age, 36 years; range, 22-58; number of DSM-III-R criteria met for benzodiazepine substance dependence, > or = 7 out of 9 [73%], all 9 criteria [40%]) used benzodiazepines and other drugs over prolonged periods of time at high doses, and their daily functioning was substantially impaired (Mean Global Assessment of Functioning Score, 48; range, 31-60). The most common lifetime psychiatric diagnoses were major depression (33%), other psychoactive drug dependence (100%) (opioids, 77%; alcohol, 53%), and panic disorder (30%). Current psychiatric diagnoses in addition to benzodiazepine dependence included other psychoactive substance use disorders (83%) (opioids, 67%; cocaine, 13%; multiple concurrent substance use, 17%), panic disorder (13%), and generalized anxiety disorder, (20%). Personality disorders included antisocial (42%), avoidant (25%), and borderline (17%). These findings demonstrate that in patients severely dependent on benzodiazepines, additional psychoactive substance use and mental disorders are prominent. The pattern of drug use and psychiatric comorbidity differentiates these patients from therapeutic-dose benzodiazepine users.

Abstract
Records of inpatients (N = 1,483) over a three-year period at an addiction treatment center were evaluated for the presence of benzodiazepine (BZ) dependence (N = 136). The preferred BZ for 43% of the subjects was diazepam, and alprazolam for 14% of subjects. Chlordiazepoxide, lorazepam, and clorazepate were each the preferred BZ for 4% of patients. Cocaine and opioid abusers were six times more likely to abuse diazepam than any other BZ. Alprazolam patients required a significantly longer period of detoxification than diazepam patients. Four percent of BZ-dependent patients (N = 6) abused BZs only and had no other substance abuse history.

Abstract
This study was conducted in Halifax, Nova Scotia, in a 740 bed university general hospital. For a period of two years, a prospective collection of data on 692 psychiatric consultations showed that 60% of all consultations came from internal medicine departments. Medical and psychiatric comorbidity was found in 50% of the patients; depression was diagnosed in 27.5% of the cases but schizophrenia in only 1.7%. Suicidal ideation was reported by 24% of the patients, 11.6% of them wishing to die imminently. More than 50% of suicidal patients were under 35 years of age; 42% of them were dependent on alcohol. Almost 30% of the patients seen in consultation admitted to being addicted to alcohol, 22% to benzodiazepines and 14% to illicit drugs. Among the ex-alcoholic patients, a significant dependence in benzodiazepine use was found. The patients with addictions to street drug had a greater suicide risk and were at the same time abusing alcohol. This paper will describe the overall functioning of a consultation-liaison psychiatric service and will analyze the impact of psycho-active substance abuse in a general hospital setting. The results will be compared with those in the literature.

Abstract
Considerable confusion continues to surround basic concepts for abuse, addiction, tolerance, and dependence. Clinicians may be making decisions about prescribing these medications without clear definitions and distinctions. The terms are not equivalent in meaning and should not be used interchangeably in clinical application. Moreover, they may occur together or independently and are not etiologically related. Abuse is improper use outside the standard norms. Abuse implies a violation component and a control over the use of the drug. Addiction is a preoccupation with the acquisition and compulsive use of and a pattern of relapse to drugs is spite of adverse consequences. Pervasive to the criteria is a loss of control over drug use and a lack of volitional component in the drug use. In spite of problems in definitions, studies have clearly shown that abuse, addiction, tolerance, and dependence develop commonly in benzodiazepine use.

Abstract
Reports of the withdrawal syndrome following discontinuation of diazepam and drug dependence fears have contributed to diazepam's displacement as the most popular anxiolytic agent. Reports of the withdrawal syndrome, the factors involved in withdrawal, and the remedies proposed for diazepam withdrawal symptoms are reviewed.

Abstract
After admission, 899 inpatients of a psychiatric university hospital were routinely screened for benzodiazepines (BDZ) in the urine. BDZ were detected in 134 (15%) patients with various primary diagnoses. Criteria for BDZ abuse or dependence were found in 36 patients. In 35 cases, either intake of BDZ had not been reported in the first psychiatric interview, or such a report had not been documented in the patient's charts. None of these 35 patients was found to have BDZ abuse or dependence. Psychiatric inpatients with BDZ abuse or dependence seem to report their intake of BDZ. These findings suggest that a routine screening for BDZ can hardly help to diagnose dependence within a university hospital setting. Nevertheless, an objective test for intake of BDZ may be useful in special cases.
