Single nucleotide polymorphisms in 5-HT receptors in the etiology of premature ejaculation.

Introduction And Objectives: Premature ejaculation (PE) is characterized by shorter intravaginal ejaculation latency time than it is acceptable for the patient or partner. It is thought that lifelong PE is a neurobiological dysfunction associated with genetic predisposition and with central serotonin neurotransmission dysfunction in receptors. To contribute to the understanding the genetic etiology of lifelong PE, it was planned to compare the 5-HT2C receptor gene rs3813929, rs518147, 5-HT1A receptor gene rs6295, 5-HT1B receptor gene rs11568817 of lifelong PE patients to healthy controls.

Association of Nicotine Use Disorder with Neurexin 3 Gene Polymorphisms.

Objective: In this study, we aimed to investigate the Neurexin 3 gene (NRXN3) polymorphisms in the rs 221473, rs 221497, rs1004212 and rs11624704 regions in relation to nicotine use disorder (NUD) in the Turkish population.

Method: Power analysis indicated that the NUD group and the control group of this study should each comprise 200 participants in the 18-65 year age range. The NUD group consisted of individuals without a psychiatric first axis disorder except for NUD, mental retardation, past head trauma or a neurological disorder, who had smoked minimally10 cigarettes per day for at least 1 year.

Objective: In this study, we aimed to investigate the effect of chronic cigarette smoking on the cognitive function in people who have no other mental or physical illness other than tobacco use disorder.

Method: The study was carried out on three groups: smokers (n = 71), former smokers (n = 39), and non-smokers (n = 49). The Wisconsin Card Sorting Test (WCST), Stroop Color and Word Test (ST), Trail Making Test (TMT), Auditory Verbal Learning Test (AVLT), and Serial Digit Learning Test (SDLT) were applied to the 3 groups participating in the study.

Anxiety, depression and coping behaviors with pain in cancer patients who are aware or unaware of their cancer.

Objectives: This study aimed to investigate whether there are differences in depression, anxiety, pain and styles of coping with pain between cancer patients with and without awareness of their cancer diagnosis.

Methods: In this study, 30 cancer patients aware of their diagnosis and 30 cancer patients unaware of their diagnosis, all of whom visited a clinic for pain treatment, were enrolled in this study. A sociodemographic information form, a questionnaire comprising questions about pain severity and related variables, Hospital Anxiety Depression Scale, and the Pain Coping Questionnaire were administered to the patients.

Theory of Mind and Selective Attention, Response Inhibition, Cognitive Flexibility in Patients with Schizophrenia.

Introduction: The aims of the current study are to investigate the relationship between selective attention, response inhibition, and cognitive flexibility that are among executive functions and sociocognitive and socioperceptual theory of mind (ToM) functions and also to investigate whether selective attention, response inhibition, and cognitive flexibility are predictive factors for ToM functions in patients with schizophrenia.

Methods: Forty-seven patients diagnosed with schizophrenia and a control group consisting of 42 individuals were administered demographic information form, Wisconsin card sorting test (WCST), Stroop test, Eye test, Hinting test. Positive and negative syndrome scale was applied to the schizophrenia group.

Prevalence of Substance Use in Patients Diagnosed with Schizophrenia.

Introduction: Substance abuse among schizophrenic patients is a growing clinical concern. Substance use disorders and their effects on the course of schizophrenia have made the identification and treatment of schizophrenic patients a high priority. This study aimed to investigate the prevalence of substance use, preferred types of substances, sociodemographic characteristics and clinical features of schizophrenia, and substance use impact in schizophrenic patients.

Evaluation of Changes in Anxiety and Depression Symptoms, and Sexual Functions in Patients Receiving Antidepressants: 3 Months-Long Naturalistic Follow-Up Study.

Objective: The aim of this study was to study the change in sexual functions within 3 months period following the initiation of antidepressant treatment in psychiatry outpatients, and its relationship with the change in anxiety and depression symptoms.

Material And Method: Eighty two patients, who consecutively applied to the psychiatry outpatient clinic and who were prescribed antidepressants, were included in the study. Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, General Assessment of Functioning Scale and Arizona Sexual Experience Questionnaire (ASEC) were administered to the patients at the first interview, then repeated on a monthly basis during 3 months.

[The Relationship between Violence and Clinical Features, Insight and Cognitive Functions in Patients with Schizophrenia].

Objective: We aimed to investigate the predictive factors of violent behavior in schizophrenia and the relationship between violent behavior and insight and cognitive functions in this study.

Method: 68 patients diagnosed with schizophrenia were separated into two groups; with a history of violent behavior (n = 30) and without (n = 38). Both group swere administered the Positiveand Negative Syndrome Scale (PANSS), Buss-Perry Aggression Questionnaire, Schedule for Assessing the Three Components of Insight, California Verbal Learning Test (CVLT), Trail Making Test, Wisconsin Card Sorting Test, and Stroop Test.

The relationship between insight and the level of expressed emotion in patients with obsessive-compulsive disorder.

Aim: The aim of this study is firstly to compare the obsessive-compulsive disorder (OCD) patients with good insight and OCD patients with poor insight in terms of socio-demographic and clinical features; to investigate the relation between insight and the level of the expressed emotion (EE) in the patients; and lastly to specify the factors that predict level of insight.

Methods: OCD patients with good insight and patients with poor insight were compared in terms of clinical features and the perceived EE level of the patients and the individuals that they live with in order to specify the factors that predict the insight level, and to investigate the relationship between insight level and EE.

Results: It was found that the total Expressed Emotion Scale, total Level of Expressed Emotion (LEE), LEE-Emotional Response and LEE-Tolerance/Expectation subscale scores of the group comprised of patients with poor insight are higher than the other group.

The first report of a patient with probable variant creutzfeldt-jakob disease in Turkey.

Variant Creutzfeldt-Jakob disease (vCJD) was first reported in the UK in 1996. Here, we report the first Turkish case of vCJD. A 47-year-old man, who has never lived outside of Turkey and had had no transfusion, was admitted to the University Hospital with speech disorder, cognitive decline and ataxia following depression, irritability, and personality change.
