Fundamental Characteristics, Attitudes and Behaviors Regarding Substance Use Focusing on Cannabis: Findings from the General Population Survey in Turkey, 2011.

Cannabis is the most prevalent illicit drug used in the world. We aimed to determine prevalence and some characteristics of cannabis use in Turkey. The study was based on a cross-sectional survey conducted with a nationally representative sample of 8045 individuals with in-house interviews. The life-time prevalence of substance use was found as 2.8%. Cannabis with 0.7% life-time prevalence, was the most commonly used substance. Cannabis users were concerned about some adverse outcomes such as anxiety with withdrawal (14%), losing control about using the drug (14%), daily performance problems (10.9%) and problems about interpersonal violence (6.9%). 35.1% of them wanted to quit and 18% regretted using cannabis. Prevalence of cannabis use is lower in Turkey compared with most of the other countries in the world. Nevertheless, it is a significant health concern. Identifying characteristics and attitudes related with cannabis use may help to improve policies about protective measures.

Clozapine-Induced Obsessive-Compulsive Symptoms and Augmentation with Clonazepam: Risks and Rationales. / Klozapine Bagli Gelisen Obsesif-Kompulsif Semptomlar ve Klonazepam ile Güçlendirme Tedavisi: Riskler ve Gerekçeler.

Obsessive-compulsive symptoms induced by clozapine negatively affect treatment compliance. In some studies, clonazepam was shown to be beneficial in obsessive-compulsive disorder. However, in literature there are case reports of life-threatening complications associated with the combined use of clozapine and benzodiazepines. In this article, the efficacy and safety of the clonazepam augmentation were discussed in two patients who had obsessive-compulsive symptoms induced by clozapine. No life-threatening complications were detected during the follow-up period of more than two years, and the patients benefited dramatically from the addition of clonazepam. In treatment-resistant patients, clonazepam can be used with close monitoring for obsessivecompulsive symptoms associated with atypical antipsychotics. Keywords: Atypical antipsychotics, clonazepam, clozapine, obsessivecompulsive symptoms.

Readmission Rates and Causes Within The First Six Months After Discharge in Patients with Alcohol Addiction.

INTRODUCTION: Readmission rate is an important criterion that evaluates the quality of treatment and care. In this study, it was aimed to determine the rates of readmission and variables predicting readmission in patients with alcohol addiction. METHODS: The study sample consisted of 264 alcohol addiction patients with recurrent admissions between 2005-2017 at the Gazi University Hospital Alcohol and Drug Addiction Clinic. In the study, ICD-10 diagnostic classification was used. The differences between the medical comorbidity and psychiatric comorbidity of the patients during the first and second admissions were analyzed. RESULTS: The average age of the study sample was 51.45±12.04 and 89% (n=235) were male. In the second admission, the comorbid headaches (p=0.001), psychotic symptoms (p=0.013), anxiety disorder (p=0.003) and substance addiction (p=0.027) were significantly higher, and the length of hospital stay was shorter. In the first six months, 24.2% (n=64) of the sample was hospitalized again. While the comorbidity of anxiety disorder increased the risk of readmission within six months 2.2-fold (OR=2.240; p=0.031), the short duration of hospitalization (less than 35 days) increased the risk of readmission 2-fold (OR=0.492; p=0.026). DISCUSSION: Patients with a short hospital stay have an increased risk of readmission within the first 6 months after discharge. Policies that reduce the length of hospital stay in health services should be reviewed. However, it is noteworthy that in the second admission of patients with alcohol dependence, the diagnosis of drug addiction is added. To prevent this, issues related to substance abuse prevention should be addressed during the treatment stages of alcohol dependence.

Giant Virchow- Robin spaces may play a role at headache attributed to hypoxia and/or hypercapnia.

According to International Classification of Headache Disorders (ICHD-III Beta version) headache attributed to hypoxia and/or hypercapnia is classified under the 4 title: 10.1.1 High altitude headache, 10.1.2 Airplane travel associated headache, 10.1.3 Diving headache and 10.1.4 Sleep apnoea headache. Headache associated with airplane travel is encountered infrequently in our clinical practice and firstly reported in 2004 as a case in the literature. The pathophysiology of headache associated with airplane travel is not yet clear. We presented this case in the aspect of the patient having both airplane travel and high altitude headaches and seen giant Virchow-Robin spaces in cranial MRI and disappearence of pain with a preventive treatment.

Assessing the validity and reliability of the Turkish versions of craving beliefs and beliefs about substance use questionnaire in patients with heroin use disorder: demonstrating valid tools to assess cognition-emotion interplay.

BACKGROUND: Cognitions associated with craving and substance use are important contributors for the psychological theories of Substance use disorders (SUD), as they may affect the course and treatment. In this study, we aimed to validate Turkish version of two major scales 'Beliefs About Substance Use'(BSU) and 'Craving Beliefs Questionnaire'(CBQ) in patients with heroin use disorder and define the interaction of these beliefs with patient profile, depression and anxiety symptoms, with an aim to use these thoughts as targets for treatment. METHODS: One hundred seventy-six inpatients diagnosed with heroin use disorder and 120 participants in the healthy comparison group were evaluated with CBQ, BSU, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and sociodemographic data questionnaire. Patient group was also evaluated with Addiction Profile Index. Reliability and validity analysis for scales were conducted. Linear regression analysis was conducted to evaluate the determinants of BSU and CBQ scores. RESULTS: Cronbach alpha level was 0.93 for BSU and 0.94 for CBQ. Patient group showed significantly higher CBQ, BSU, BAI and BDI scores (p < 0.001). BSU score significantly correlated with API-substance use profile score, API-diagnosis, BAI, BDI and CBQ (p < 0.005), whereas CBQ scores significantly correlated with API-diagnosis, API-impact on life, API-craving, API-total score, BSU, BAI, BDI and amount of cigarette smoking (p < 0.002). Number of previous treatments and age of onset for substance use were not correlated with either BSU or CBQ. BAI and BDI scores significantly predicted BSU score, however only BDI score predicted CBQ score (p < 0.003). CONCLUSIONS: Craving beliefs were highly correlated with addiction profile. Anxiety and depression are significant modulators for patients' beliefs about substance use and depression is a modulator for craving and maladaptive beliefs, validating emotion-cognition interplay in addiction.

Visual evoked potentials in chronic alcoholism.

In order to evaluate the effect of alcohol consumption and the effect of abstinence on central nervous system generated parameters, we performed pattern visual evoked potential (PVEP) recordings on chronic alcoholics. The study was conducted on forty patients diagnosed as chronic alcoholics according to DSM IV criteria. They were aged mean: 42, and had histories of alcohol abuse for at least six years (mean: 21). 15% of the patients demonstrated abnormal VEP results at least in one tested eye. In order to test the effect of abstinence period on P100 latency values, alcoholics were divided in to two subgroups. Group I (Gr I) consisted twenty-four alcoholics who had been abstinent for less than thirty days (mean: 14), and Group II (Gr II) consisted sixteen alcoholics who had been abstinent for more than thirty and less than seventy-six days (mean: 38) The mean P100 latency of Gr I and Gr II was 101 and 102 milliseconds (ms) respectively; and when compared to normal controls the difference was statistically significant (p: 0.016, p: 0.009). Abnormal VEP in asymptomatic chronic alcoholics suggests that they may be useful in the detection of early changes and in following the progress of patients with the disorder.

Prevalence and Socio-Demographic Determinants of Tobacco, Alcohol, Substance Use and Drug Misuse in General Population in Turkey.

INTRODUCTION: The aim of the current study is to determine prevalence ratios of tobacco, alcohol, substance use and drug misuse in a large scale sample of general population and recognize related socio-demographic factors. METHODS: The study was based on a cross-sectional survey conducted with a nationally representative sample of 8045 individuals with face-to-face, in-house interviews implemented by a trained team of interviewers. RESULTS: Life-time prevalences of tobacco, alcohol, substance use and drug misuse are 51.8%, 28.3%, 2.8% and 10.5% respectively. Age, gender, education level and marital status are important socio-demographic determinants for tobacco, alcohol use and drug misuse. Income level is an important determinant for alcohol and substance use. CONCLUSION: Tobacco, alcohol, substance use and drug misuse are significant health concerns in Turkey. Socio-demographic status is an important determinant of several aspects of tobacco, alcohol, substance use and drug misuse and should therefore be evaluated carefully to develop effective protective and preventive strategies.

Depression and anxiety in patients with Behçet's disease compared with that in patients with psoriasis.

BACKGROUND: Behçet's disease (BD) is a chronic, episodic disease with an often devastating course. The aim of this study was to evaluate the depression and anxiety levels in patients with BD and to compare them with those in patients with psoriasis. METHODS: Patients were collected from the Dermatology Department, Faculty of Medicine, Gazi University, Ankara, Turkey. One hundred and twelve patients with BD and 95 patients with psoriasis were enrolled in the study. Patients were evaluated by Beck's depression inventory (BDI), Beck's anxiety inventory (BAI), automatic thoughts questionnaire (ATQ), and Beck's hopelessness scale (BHS). RESULTS: The group with BD had higher scores for BDI, BAI, ATQ, and BHS than the group with psoriasis (P < 0.05). Almost one-half of the patients with BD had depression. BAI only was higher in the younger BD group than in the corresponding psoriasis group, whereas all test scores were higher in the older BD group than in the corresponding psoriasis group. There was a strong correlation between the duration of BD and BDI, ATQ, and BHS scores, which was not observed in the psoriasis patients. BD increased the depression risk four-fold in this sample, and BD with a duration of over 3 years increased the depression risk 12-fold. CONCLUSIONS: In the present study, BD patients had higher levels of psychopathology than did psoriasis patients in terms of psychologic test scores. The duration of illness affected the severity of the psychiatric symptoms in the BD group, but not in the psoriasis group. The duration of illness was a major risk factor for the development of depression in BD. These findings indicate the need for early recognition of psychiatric symptoms in patients with BD.

Comparison of liver hemodynamics according to doppler ultrasonography in alcoholic patients subtyped by Cloninger classification and non-alcoholic healthy subjects.

BACKGROUND: The aim of this study was to search for morphological and hemodynamic changes in hepatic and splanchnic vasculature in alcoholic patients without the signs of hepatic damage and subtyped by Cloninger classification by means of sonography, and compare the subtypes among themselves and with nonalcoholic healthy subjects. METHODS: Thirty alcohol dependent patients and 30 healthy subjects with no alcohol problem or hepatic impairment were included in the study. Patients were subtyped by Cloninger classification and all patients were evaluated by gray-scale and spectral Doppler ultrasound. The diameter of the portal vein, portal venous velocity, peak systolic and end diastolic velocities of hepatic and superior mesenteric arteries were assessed. RI, PI and systolic/diastolic velocity ratios were also calculated. RESULTS: Portal vein diameter (PV diameter), portal vein cross sectional area (PV area), portal vein velocity (PV PSV), hepatic artery peak systolic velocity (HA PSV), hepatic artery end diastolic velocity (HA EDV), hepatic artery resistive index (HA RI), hepatic artery pulsatility index (HA PI), and systolic/diastolic velocity ratios (HA S/D), superior mesenteric artery peak systolic velocity (SMA PSV), superior mesenteric artery end diastolic velocity (SMA EDV), superior mesenteric artery resistive indices (SMA RI), pulsatility index (SMA PI), and systolic/diastolic velocity rates (SMA S/D) showed no significant difference among the groups (P > 0.01). Although there is no significant difference in PV PSV, HA PSV, SMA PSV, SMA EDV values between the groups, mean values of Type II alcoholics is greater than other groups. Portal vein cross-sectional area was greater in alcoholic patients (Type I, II and III) compared to the control group (P = 0.000). Portal vein velocity, hepatic artery peak systolic and end diastolic velocity, superior mesenteric artery peak systolic and end diastolic velocity were significantly greater in alcoholic patients than in the control group (P < 0.001). No statistical difference was detected between other parameters evaluated. CONCLUSION: In alcohol dependent patients, some hemodynamic and morphologic changes occur in hepatic and splanchnic circulation, even before the signs of hepatic damage develop, which can be detected by means of Doppler and gray-scale sonography. But as there is no significant difference between the Doppler ultrasonographic findings among alcoholics subtyped by a Cloninger classification, which is a clinical classification, it suggests that psychiatric classification doesn't show any correlation with biological parameters, and because of this Cloninger classification a psychiatric classification cannot be considered as a characteristic determinative factor in the prognosis of hepatic disorder due to alcohol use. However, higher values of Type II alcoholics can be attributed to the longer alcohol intake of this subtype.

Increased frequency of sister chromatid exchanges in peripheral lymphocytes of alcoholics and cigarette smokers.

Sister chromatid exchange (SCE) is a sensitive indicator of genotoxicity. In this study we investigated the effects of alcohol consumption and cigarette smoking on the frequency of SCE in cultures of peripheral lymphocytes. The rate was higher in alcoholics who smoked (10.89+/-2.46) and in smokers (positive controls) (7.64+/-1.01) than in healthy non-smokers (negative controls) (6.96+/-2.18). Statistical analysis suggested that the increases were related to alcohol consumption and cigarette smoking (p<0.05).
