[Immune-inflammatory and autoimmune mechanisms in postpartum depression].

Postpartum depression is a debilitating mental disorder with a high prevalence, usually related with a past psychiatric history of major depressive disorder, postpartum depression, bipolar disorder, premenstrual syndrome (PMS), and perinatal depressive symptoms during gestation. However, the existing literature does not sufficiently elucidate the pathophysiology of this clinical entity which appears in such a crucial period of woman's life. This review aims to search the available data regarding the involvement of immunological and autoimmune mechanisms in its onset.

Basal Ganglia Calcification: A Case Report of Fahr Disease With Pure Psychiatric Symptoms.

Fahr disease, also known as familial idiopathic basal ganglia calcification, is a rare neurodegenerative disorder, the etiology of which remains unknown. Given its various presentations, Fahr disease is presumed to be underdiagnosed and its prevalence underestimated. We present a case of Fahr disease that presented mainly with pure psychiatric symptoms.

Psychiatric comorbidity in chronic urticaria patients: a systematic review and meta-analysis.

Background: Dermatological illness can affect the quality of life and may coexist with psychiatric disorders.

Objective: The aim of this review was to systematically evaluate the published evidence of any psychiatric disorders that may coexist with chronic urticaria (CU) and any effect psychiatric interventions may have on CU.

Methods: Following the Cochrane guidance, we conducted a systematic literature search using web-based search engines provided by PubMed (for Medline database), Google Scholar and Scopus for studies that have investigated the existence of psychiatric comorbidity in patients with CU.

[Kynurenine pathway in bipolar disorder].

Bipolar disorder (BD) is a chronic psychiatric illness which, among other things, is characterized by cerebral dysfunctions, cognitive disorders and sleep disturbances. The neurobiological basis of these processes remains unclear. In recent years, studies have focused on the role of immune-inflammatory mechanisms induced by the tryptophan metabolism pathway (TRP) and the kynurenine pathway (KYN).
