Delusion of pregnancy: Case series.

Delusion of pregnancy is a relatively uncommon manifestation in psychotic patients. Differentiating it from closely related clinical entities like pseudocyesis/pseudopregnancy can be a challenge in clinical setting. Diagnosis of a psychotic illness with delusional pregnancy as the presenting feature in the absence of other florid symptoms of psychosis is a different challenge altogether. Currently, there is no consensus on the pharmacotherapy and psychotherapy of delusional pregnancy. We present a case series on delusional pregnancy with the intent to answer some of these gaps in the literature.

To study childhood trauma in patients with bipolar affective disorder and its association with leucocyte telomere length.

Background: Childhood traumatic (CT) events are more frequent in Bipolar Affective Disorder (BD) than in healthy individuals. As per existing studies, telomere shortening might be associated with psychiatric illnesses and aging-related disorders. One basis could be CT in BD aiding in telomere shortening. Methods: 100 BD patients and 100 healthy controls (HC) were matched for age and sex. All the participants were administered Childhood Trauma Questionnaire (CTQ). Subsequently, Quantitative Polymerase Chain Reaction (q-PCR) was performed in order to verify leukocyte telomere length (LTL) for both cases and controls. Results: Presence of subtypes of moderate to severe CT among cases revealed emotional abuse in 35%, physical abuse in 16%, and sexual abuse in 15%. BD patients had significantly shorter telomeres in comparison to HC. BD patients with CT had significantly shorter LTL as compared to healthy controls with CT. The association between CT and LTL was not statistically significant in cases as well as in controls. Conclusions: Our study revealed presence of CT (moderate to severe) in 46% of BD patients and 12% in age and sex-matched healthy controls. All CT subtypes except sexual abuse were significantly higher among cases than in healthy controls. Mean score of LTL among cases including that with CT was significantly lower than the healthy controls.

Childhood trauma and bipolar affective disorder: Is there a linkage?

Bipolar affective disorder (BPAD) is a major psychiatric illness impairing the quality of life. The etiology of BPAD is influenced by different factors possibly related to gene-environment interactions. Approximately 30% to 50% of individuals with BPAD have experienced some traumatic event in childhood. Serious adverse experiences that children may suffer early in life are often described as childhood trauma (CT). It includes physical, emotional, and sexual abuse and physical and emotional neglect. CT is linked with an elevated risk of developing BPAD. Childhood adversities play a role in modulating the early onset of illness, increased number of depressive episodes, increased suicide attempts, and other clinical severity of BPAD. Hospital-based studies comprising heterogeneous populations had researched the specific role of each trauma subtype as a predisposing factor for BPAD. Identifying and addressing CT through early intervention methods may prevent the future development of chronic disorders like BPAD. This review article is an attempt to explore and highlight the existing literature regarding the association of different subtypes of CT with BPAD.

Gut-brain axis: Synergistic approach.

Since decades, there is a change in concept of the gut-brain axis. There is differential increase in evidences focusing on the bidirectional communication between the gut microbiome and the brain. It supports existence of far-reaching model of "gut-brain axis." This axis is attaining more adherence to fields investigating biological and physiological footing of psychiatric, neuro-developmental, age-related, and neurodegenerative disorders. Many factors can change microbiota composition in early life as well as with the increasing age. Stress can affect the microbiota-gut-brain axis at every stages of life. Recent advances have involved the gut microbiota in many conditions including severe mental illness, autism, anxiety, obesity, Parkinson's disease, and Alzheimer's disease. The current studies target on elaborating the underlying mechanisms of microbiota-gut-brain axis and attempt to exemplify intervention and therapeutic strategies for neuropsychiatric disorders.
