Patients and methods A total of 30 recovering substance-dependent women were selected as consecutive samples from private hospitals, private clinics, and private rehabilitation centers in Greater Cairo. Moreover, 30 controls were included who were nonsubstance-dependent volunteer women. All participants gave written consent and were subjected to the following interviews, assessments, and investigations: informed consent, Structured Clinical Interview for DSM axis I, Addiction Severity Index for cases, Social Support Questionnaire, Social Competence Scale, and urine sampling for cases. Results Most recovering substance-dependent women were single, mostly divorced, and unemployed. Benzodiazepines were the most common substance of abuse followed by opiates and alcohol. The period of sobriety was 6 months to 1 year in half of the cases. The addiction severity index revealed most cases had severe drug and alcohol use, severe psychiatric problems, and severe problems in their social relationships owing to drug dependence, and approximately half of the cases had severe medical and legal problems owing to drug dependence. Most of the recovering substance-dependent women showed low social competence and had limited to fair level of social support in their recovery. All recovering substance-dependent women had a psychiatric diagnosis. Major depressive disorder and posttraumatic stress disorder are the two most common psychiatric disorders found in recovering substance-dependent women. Conclusion There is a high prevalence of psychiatric disorders among recovering substance-dependent female patients. Their social competence is low, and they tend to have limited to fair social support throughout the process of recovery.","PeriodicalId":76626,"journal":{"name":"The Egyptian journal of psychiatry : official journal of the Egyptian Psychiatric Association","volume":"40 1","pages":"64 - 73"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47136988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective In this study, we have analyzed the psychiatric problems of infertile women, their coping capability to stressful life events, and marital satisfaction among them. Patients and methods In a cross-sectional study, 30 infertile women (15 explained and 15 unexplained infertility) were randomly selected and advised to a clinical psychiatric assessment and to fill up Stressful Life Events Coping questionnaire and Marital Satisfaction Inventory. After obtaining their consents, psychiatric problems such as depressive disorders, anxiety disorders, panic, somatoform disorders, and personality profile were assessed. Moreover, their coping capability to stressful life events and marital satisfaction was studied. Results were analyzed and compared with the results from 10 fertile women. Results According to a clinical psychiatric assessment, Stressful Life Events Coping questionnaire, and Marital Satisfaction Inventory, major depression, anxiety disorders, comorbid anxiety and depression, and premenstrual dysphoric disorder were significantly more frequent in infertile women. Considering somatization and personality disorders, there was no significant difference between infertile and fertile women. Pathological coping capability to stress and marital dissatisfaction, on the contrary, was significantly higher among infertile women. Conclusion Infertility may be considered as one of the major casual factor in depression and anxiety disorders, has negative coping capability to stress, and shows marital dissatisfaction.","PeriodicalId":76626,"journal":{"name":"The Egyptian journal of psychiatry : official journal of the Egyptian Psychiatric Association","volume":"40 1","pages":"74 - 85"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49078559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insufficient nutritional supply and deficiency of trace elements and other components including various minerals have been suggested to play a role in the development of ADHD symptoms. Zinc in particular was found to be significantly deficient in patients with ADHD compared with healthy controls, so it was concluded that zinc deficiency might play a role in the etiopathogenesis of ADHD. Objectives The aim of the work is to investigate the association of serum zinc levels with ADHD diagnosis, its symptom domains, and severity. Patients and methods A total of 75 children aged from 6 to 14 years with Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) diagnosis of ADHD were enrolled in this study. All children were assessed using Colored Progressive Matrices IQ test, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime version (K-SADS-PL), the Working Memory Index (WMI) of Wechsler Intelligence Scale for Children (WISC-III), and Conner’s Parent Rating Scale − Revised − Long version (CPRS-R-L). Serum zinc level was measured in all children using atomic absorption spectroscopy. Results Overall, 52% of children with ADHD (n=39) had forthright zinc deficiency with serum zinc levels less than 60 μg/dl. Five children only had marginal zinc levels, with serum zinc level ranging between 60 and 80 μg/dl. Serum zinc levels were lower in children living in rural areas. Zinc-deficient children showed lower IQ scores than non-zinc-deficient group.","PeriodicalId":76626,"journal":{"name":"The Egyptian journal of psychiatry : official journal of the Egyptian Psychiatric Association","volume":"40 1","pages":"95 - 103"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47477973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessment of insight in psychiatric patients is important as it is implicated in the course of illness, adherence to treatment, and prognosis. Objective The aim was to evaluate the level of insight in schizophrenia spectrum disorders and also in bipolar and major depressive disorders with psychotic features and to examine the relationship between level of insight and sociodemographic and illness-related characteristics, including severity of symptoms. Patients and methods A total of 85 patients diagnosed with schizophrenia spectrum disorders (group 1) and 44 patients diagnosed with bipolar disorder with psychotic features and major depressive disorder with psychotic features (group 2) who were admitted to Minia Psychiatry Hospital in a period of 6 months were included in the study. Diagnosis was done using Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-5 research version. Level of insight was assessed using Scale to assess Unawareness of Mental Disorder assessing awareness of mental disorder, awareness of the need for treatment and awareness of social consequences of mental disorder. Severity of symptoms and psychopathology was assessed using Positive and Negative Syndrome Scale and Clinical Global Impression Scale (CGI). Results Patients diagnosed with schizophrenia spectrum disorders (group 1) tended to have poorer insight than those with bipolar affective disorder (BAD) and major depressive disorder (MDD) with psychotic features (group 2) on admission and also on discharge. Levels of insight of both groups differed significantly on discharge when compared with their levels of insight on admission, but that difference was more profound in group 2. Stepwise multiple linear regression analysis predicting level on insight revealed that blunted affect, lack of judgment and insight, conceptual disorganization, and CGI severity of illness were the most implicated factors in determining insight on admission whereas CGI efficacy index, grandiosity, motor retardation, and passive/apathetic social withdrawal were factors determining insight on discharge. Conclusion Patients diagnosed with schizophrenia spectrum disorders have poorer insight than those diagnosed with BAD and MDD with psychotic features. Predictors of insight differ on admission than on discharge.","PeriodicalId":76626,"journal":{"name":"The Egyptian journal of psychiatry : official journal of the Egyptian Psychiatric Association","volume":"40 1","pages":"48 - 57"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70724171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods A total of 40 adult patients aged from 20 to 50 years, with idiopathic epilepsy recruited from the outpatient clinic of South Valley and Assiut University hospital and a similar number of age-matched and sex-matched controls were included. Participants completed Wechsler Intelligence Scale and neuropsychological tests including Wisconsin card sorting test, trail making test (trails A and B), Conners’ continuous performance test, and digit span tests. Results Relative to the control group, patients poorly performed on most of executive functions, with the longer duration of illness and the higher frequency of seizures being the most evident factors that showed a positive correlation with the executive dysfunction. However, age at onset, type of seizures, and family history of epilepsy had no significant correlation on neuropsychological test performance. Conclusion One of the main domains of evaluation of the patients with chronic epilepsy should be the cognitive domain. A large number of studies shed light on such hypothesis. Executive dysfunction in patients with epilepsy may share negatively in their quality of life, so it should be a target of diagnosis and therapy.","PeriodicalId":76626,"journal":{"name":"The Egyptian journal of psychiatry : official journal of the Egyptian Psychiatric Association","volume":"40 1","pages":"31 - 34"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70723753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

El Hamed","doi":"10.4103/ejpsy.ejpsy_8_18","DOIUrl":"https://doi.org/10.4103/ejpsy.ejpsy_8_18","url":null,"abstract":"Background Bipolar disorder (BD) is a lifelong, potentially treatable psychiatric disorder with substantial morbidity and mortality. Sleep is a very important factor for the quality of life, risk for relapse, affective functioning, cognitive functioning, impulsivity, and general health. It is important to note that a bidirectional relationship likely exists between sleep disturbance and mood disorders, as symptoms of mood disorders may disrupt sleep, and disrupted sleep can increase symptoms of mood disorders. Moreover, the sources of inflammation and immune activation, which play a role in depression, may contribute to the inflammatory burden in patients with mania. Aim The aim of this study was to study the nature of sleep disturbance in bipolar patients and to detect the correlation between the severity of BD and sleep disturbance. Patients and methods In this case–control study, fifty BD patients (28 male patients and 22 female patients) and 20 age-matched controls were recruited for this study. Structured Clinical Interview for DSM-IV Axis I Disorders for diagnosis of BD; Beck Depression Inventory-II and Young Mania Rating Scale (YMRS) were used to assess the severity of BD. Assessment of sleep pattern was carried out by Pittsburgh Sleep Quality Index (PSQI), and C-reactive protein (CRP) was measured. Results In the current study, with regard to Beck scores before medication, there were inverse relations with YMRS and PSQI. These relations become direct after medication. As regards YMRS scores before medication, there was an inverse relation with Beck, direct relations with PSQI, which did not show any change after medication, except for sleep disturbance, which become an inverse relation. As regards PSQI’s total scores before medication, it showed an inverse relation with Beck, direct relations with YMRS and the relation with Beck scores became direct after medication. As regards CRP levels, there was a significant difference between cases before and after medication and significant difference between the case and control groups. Conclusion PSQI is a cheap valid test that can be used in Egypt to report sleep profile and abnormalities, to follow-up the patients and prevent relapse. Hence, bipolar patients with depressive symptoms improved and responded better on treatment, with better improvement in sleep profile than patients with manic symptoms. Moreover, a definite correlation between sleep disturbance and CRP levels could not be concluded.","PeriodicalId":76626,"journal":{"name":"The Egyptian journal of psychiatry : official journal of the Egyptian Psychiatric Association","volume":"40 1","pages":"5 - 16"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70724720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many of these patients have other personality disorders as well. They tend to display a wide range of other psychiatric disorders, including dissociative phenomena and experiences. Patients and methods A total of 60 female patients were diagnosed with BPD using the Diagnostic and Statistical Manual of Mental Disorders, IV ed. Structured Clinical Interview for DSM-IV Axis II Personality Disorders. Severity of illness and emotional and behavioral aspects of patients were assessed using Borderline Evaluation of Severity over Time. Defense style of patients was assessed using the Defense Style Questionnaire. Dissociative phenomena were studied using the Dissociative Experience Scale (DES). Results The most commonly used defenses by the study patients were undoing, idealization, somatization, and splitting. Patients with absent criteria 4 (impulsivity) and 7 (feeling of emptiness) of BPD significantly displayed more mature defenses, whereas patients having criterion 9 (paranoid ideation and severe dissociation) of BPD significantly displayed neurotic type of defenses. Mature defenses were significantly negatively correlated with the absorption and depersonalization factors of DES. Neurotic defenses were significantly correlated with the total score of DES, absorption, and depersonalization factors. Immature defenses were significantly correlated only with the depersonalization factor of DES. Conclusion Patients with BPD have a specific pattern of defense style that might be linked to their specific illness criteria. Displaying certain phenomena of dissociation might be related to the particular pattern of the dominant defense mechanisms in these patients.","PeriodicalId":76626,"journal":{"name":"The Egyptian journal of psychiatry : official journal of the Egyptian Psychiatric Association","volume":"40 1","pages":"41 - 47"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70723872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
