Allotrichophagia: A Unique Case of Parental Adjustment to Filial Pediatric Malignancy.

A 36-year-old Hispanic female patient with gastrointestinal symptoms and weight loss was found to have a trichobezoar in her stomach requiring a surgical removal. Psychiatry team was consulted due to concerns for depression and trichotillomania. The psychiatric evaluation revealed that the patient was not ingesting her own hair - the most common instance in cases of trichotillomania and trichophagia, but her daughter's hair. The patient was doing this as an unconscious, spontaneous response to her daughter's manifest hair loss caused by daughter's malignancy and treatment thereof. The patient was given a diagnosis of Adjustment disorder and treated as such, as the patient's symptoms resolved with her daughter's remission. The patient's cultural background was taken into consideration and the team explored cultural factors that could have mediated such a response. The team also explored the psychodynamic aspects of this case in order to attain a more comprehensive understanding of this patient's unique presentation. To best describe this unusual behavior, we coined a term for such a phenomenon - allotrichophagia (Greek: eating others' hair).

Cultural Representations of Borderline Personality Disorder.

Background/Objective: Borderline Personality Disorder (BPD) is characterized by unstable interpersonal relationships, impulsivity, and self-harm. There are many distinct stressors that predispose individuals to develop BPD or engage in self-harm behaviors. The objective of this systematic review was to compare methods of self-harm and psychological stressors in BPD across different cultures. Methods: A PubMed database search was conducted with the goal of capturing all articles (n = 22) that discussed methods of self-harm in BPD in any culture. Data extracted from the articles included methods of self-harm, psychological stressors, sample size, rurality, geographical location, and proportion of males to females. Results: Key differences were noted in the methods of self-harm. Eastern nations (n = 5) reported higher rates of self-poisoning (60%) than Western nations (11%). Western nations (n = 9) reported higher rates of skin-mutilating behavior (100%) than Eastern nations (80%). Two of the articles included participants from rural settings, one in the Sundarban region of India and the other in Mississippi. Notably, the Sundarban region reported the highest rate of poisoning (93%) whereas the Mississippi region reported high rates of skin mutilation. Differences were also noted in psychological stressors as the rates of interpersonal problems were higher in Western than in Eastern nations. Conclusions: Additional research should be conducted into the presentation of BPD in different cultures. An improved understanding of the cultural presentations of BPD could improve diagnosis and treatment in various populations.

Associations between estrogen and progesterone, the kynurenine pathway, and inflammation in the post-partum.

BACKGROUND: Depression during and after pregnancy is common, affecting at least 15% of women. Features of depression in pregnancy range from mild symptoms of disrupted mood and interest to severe depression and suicidal behavior. Previous studies suggest hormone- and immune dysregulations might contribute to post-partum depression, but consistent evidence is lacking. METHODS: A total of 163 women were included in the study in the post-partum. Peri-partum depression (PPD) was diagnosed using SCID interviews and depressive symptoms were quantified using the Edinburgh Perinatal Depression Rating Scale (EPDS), retrospectively long-term, as well as acutely. Plasma estrogen, progesterone, pro- and anti-inflammatory cytokines and kynurenine metabolites were measured in the post-partum. RESULTS: Higher estrogen and progesterone in the post-partum were linked to more severe depressive symptoms over pregnancy. In the post-partum, estrogen was positively correlated with the pro-inflammatory cytokine IL-6 and negatively correlated with kynurenine and picolinic acid. Conversely, progesterone was negatively correlated with IL-1ß and several metabolites in the kynurenine pathway, including quinolinic acid. LIMITATIONS: Associative study design, did not attempt to assess causality. Did not adjust hormone levels for medication effects. CONCLUSIONS: Our study suggests that higher sex hormones in the post-partum are linked to depression severity over pregnancy. Estrogen was coupled with a pro-inflammatory profile and neurotoxic kynurenine metabolites, whereas progesterone was linked to an anti-inflammatory profile in the post-partum.

Inflammation and kynurenine pathway dysregulation in post-partum women with severe and suicidal depression.

Depression during pregnancy and the post-partum is common, with severe cases resulting in suicidal behavior. Despite the urgent and unmet medical need, the biological underpinnings of peri-partum depression remain unclear. It has been suggested that it is triggered by dynamic changes of the immune system during pregnancy and at delivery. Therefore, we investigated whether a pro-inflammatory status in plasma, together with changes in the kynurenine pathway activity, is associated with the development of severe depression and suicidal behavior in the post-partum. Our cross-sectional study targets a unique, understudied population in which the pronounced severity of symptoms required hospitalization. We analyzed plasma IL-1ß, IL-2, IL-6, IL-8, TNF-α, tryptophan, serotonin, kynurenine, nicotinamide, quinolinic- and kynurenic acids in post-partum women diagnosed with peripartum onset depression (PPD) and healthy controls (n = 165). We assessed depression severity using the Edinburgh Postnatal Depression Scale and suicidality using the Columbia-Suicide Severity Rating Scale. We found that increased plasma IL-6 and IL-8 and reductions of serotonin, IL-2 and quinolinic acid were associated with the severity of depressive symptoms and increased the risk for PPD. Moreover, women with lower serotonin levels were at an increased risk for suicidal behavior, even when adjusting for depression severity, psychosocial factors, age BMI, and medication. Our results indicate that severe depression in the post-partum involves dysregulation of the immune response and the kynurenine pathway, with a concomitant reduction in serotonin levels. We propose that inflammatory cytokines and the kynurenine pathway are potential treatment targets in PPD, opening up the possibility of novel therapeutic strategies targeting the peripartum.
