Purpose of ReviewThis systematic review aimed to investigate the relation between cannabis use and dissociation.Recent FindingsFour analytical and 14 descriptive cross-sectional studies were included. There is no variation in the rates of cannabis use among individuals with dissociative experiences compared with the general population. In addition, the prevalence of dissociative disorders in subjects using cannabis is not different from those not using cannabis. The majority of the studies employed inadequate sampling procedures and a concurrent or retrospective assessment of the two variables, which might have increased the risk of bias, and only a few of them controlled for potential confounders.SummaryThe limited number of eligible studies, combined with the heterogeneity of study design and methodological limitations, do not support the association between cannabis and dissociative experiences and prevent from any inference about the direction of causality.

Introduction: Hypothyroidism is a common disorder of the endocrine system in which the production of thyroid hormones is inadequate. In addition to various physical manifestations, patients who suffer from hypothyroidism may also present with psychological problems, as described in previous studies. Case Presentation: Herein, the reports of 2 patients who suffered from hypothyroidism and experienced improvement in their psychological symptoms after levothyroxine therapy are presented. The patients referred with depressive mood with psychotic features and psychomotor retardation. Treatment simultaneously with psychopharmacotherapy and hormone therapy was considered. Conclusion: Although hypothyroidism and depressive disorders are separate issues, hypothyroidism can induce depression and psychosis, and psychopharmacotherapy plus hormone therapy can be effective and boost treatment.

Vitamin B12 affects and modify the function of multiple organ systems. Its deficiency may cause psychiatric symptoms in addition to hematologic, gastrointestinal, and neurologic manifestations. The present case study aims to report a patient with vitamin B12 deficiency who coexisted with resistant and persistent depression, and experienced mania phase after the replacement of vitamin B12. For a patient with refractory and resistant depression and evidence or a risk factor for vitamin B12 deficiency, it is required to check plasma levels and monitor psychiatric symptoms during vitamin B12 supplementation. There are some manifestations of B12 deficiency including bipolar disorder, mood lability, irritability, and psychosis due to deficiency but we didn’t find case report about induce of psychiatric presentation follow correction of vitamin B12 deficiency .

The concept of catatonia was first described by a German psychiatrist, Kahlbaum, in 1874. Catatonia is a serious neurological disorder associated with a wide range of psychiatric, neurological, medical conditions, and drug-induced disorders. Nevertheless, there is no absolute guideline for treating catatonia patients in whom the cause of the disorder is unknown. Clozapine is the first atypical antipsychotic used for the treatment of catatonia. Our case was a 51-year-old single, right-handed man with schizophrenia and a specific symptom of catatonia. Despite previous studies findings revealing the efficacy of clozapine in relieving catatonia symptoms, our patient did not show a definite response to this medication. Hence, follow-up of these patients to evaluate other treatments and possible incidence or manifest of other catatonic features like waxy flexibility, echo phenomenon, and negativism are suggested.

Heterogeneous findings have been reported regarding the effects of anti-depressive drugs over platelet counts. Among antidepressant drugs, Selective Serotonin Reuptake Inhibitors (SSRIs) has been shown to reduce platelet aggregation. We report a patient with reduction in her platelets counts as well as bruising occurrence following three days of receiving sertraline. In patients with a history of bleeding, ITP or familial ITP, their psychiatric treatment and prescribing SSRI should be done with caution.

Around 800 000 to 1 million people die by suicide annually, making suicide the 10th leading cause of death worldwide. Suicide rates are higher among men than women, and the probability of suicide is 3 to 4 times higher for men than for women. Non-lethal suicide is more common in young people and women. The type of suicide seen in different countries depends on the culture, economic, and social conditions in the respective country. Also, differences in types of suicide are partly due to the availability of various methods. In recent years, the percentage of suicides has risen in all countries. Surveys show that the most prominent methods of suicide in most countries in the world are hanging and poisoning. The most deadly type of suicide is by gun. The most unsuccessful suicide attempts are overdoses of medication. Knowing about the available suicide methods is important.

We present a 19-year-old patient with hematologic and neurologic manifestations associated with Wilson's disease. Idiopathic thrombocytopenia was diagnosed in October 2009. Bone marrow aspiration was normal. Gradually her neurologic and psychiatric symptoms emerged, dysarthria, writing apraxia, learning difficulties, emotionalism and eventually dystonia of hands. The serum ceruloplasmin was low, and the Kayser Fleischer's ring was positive. MRI of the brain showed abnormality in the bilateral basal ganglia, brain stem and superior cerebellar peduncles without post-contrast enhancement.

The aim of this study was to directly compare efficacy of atomoxetine and methylphenidate in treatment of children and adolescents 6- 18 years. All published, randomized, open label or double blind trials, comparing the efficacy of methylphenidate with atomoxetine in treatment of children diagnosed with ADHD, using DSM-IV criteria were included in this study; ADHD Rating Scale-IV-Parent Version: Investigator Administered and Scored (ADHDRS) scores was used. The standardized mean difference (SMD) was used as a measure of effect size. Eleven studies were included with a total of 2,772 participants. The meta-analysis did not find a significant difference in the efficacy between methylphenidate and atomoxetine (SMD= 0.09, 95% CI -0.06, 0.25) (Z= 1.18, p= 0.24). Sub group analysis showed a significant standardized mean difference favoring OROS methylphenidate (SMD= 0.31, 95% CI 0.16, 0.47 (Z= 3.91, p< 0.0001); immediate release methylphenidate was not superior to atomoxetine (SMD= -0....
