Trichophagia and trichobezoar: case report

OBJECTIVE: Trichobezoar consists of a compact mass of hair occupying the gastric cavity to a various extent. When the trichobezoar extends past the duodenum it is better referred to as Rapunzel Syndrome. Although trichobezoars are well described in terms of surgical diagnostic and procedure, there are only but very scarce reports on psychiatric literature, usually associated with trichotillomania. The authors present a clinical case of trichobezoar and discuss the most relevant aspects concerning this entity. METHODS: Presentation of psychiatric and surgical data concerning the case report. Previously reported cases are also mentioned. RESULTS: Report of a 27-year-old female patient with a trichobezoar submitted to surgical removal, with a prior intervention 4 years before also due to trichobezoar, and with unknown psychiatric antecedents or follow-up. CONCLUSIONS: A trichobezoar represents a serious surgical condition. It is important to consider such diagnosis in face of suggestive symptoms, even if signs of trichotillomania are not present. The discrepancies between the prevalence of trichotillomania and trichobezoars due to trichophagia may be due to issues related to self-selection of patients and symptom severity. Such issues may also be important in the study of impulsive-compulsive spectrum models and to their relevance to impulse control disorder

A fundamental distinction in early neural processing of implicit social interpretation in schizophrenia and bipolar disorder

Background: Social cognition impairment is a key phenomenon in serious mental disorders such as schizophrenia (SCZ) and bipolar disorder (BPD). Although genetic and neurobiological studies have suggested common neural correlates, here we hypothesized that a fundamental dissociation of social processing occurs at an early level in these conditions. Methods: Based on the hypothesis that key structures in the social brain, namely the temporoparietal junction, should present distinctive features in SCZ and BPD during low-level social judgment, we conducted a case-control study in SCZ (n = 20) and BPD (n = 20) patients and controls (n = 20), using task-based fMRI during a Theory of Mind (ToM) visual paradigm leading to interpretation of social meaning based on simple geometric figures. Results: We found opposite neural responses in two core ToM regions: SCZ patients showed social content-related deactivation (relative to controls and BPD) of the right supramarginal gyrus, while the opposite pattern was found in BPD; reverse patterns, relative to controls and SCZ, were found in the left posterior superior temporal gyrus, a region involved in inferring other's intentions. Receiver-operating-characteristic curve analysis showed 88% accuracy in discriminating the two clinical groups based on these neural responses. Conclusions: These contrasting activation patterns of the temporoparietal junction in SCZ and BPD represent mechanistic differences of social cognitive dysfunction that may be explored as biomarkers or therapeutic targets.info:eu-repo/semantics/publishedVersio

Compatibilidade de porta-enxertos de Capsicum baccatum com pimentão no Distrito Federal.

Avaliou-se a compatibilidade entre oito acessos de C. baccatum que apresentam alto vigor e potencial para uso como portaenxerto do banco de germoplasma da Embrapa Hortaliças, e o pimentão 'Margarita'. Como testemunha, utilizaram-se materiais de C.annuum: o híbrido comercial Snooker, um Híbrido Simples Experimental (HSE) da Embrapa Hortaliças e plantas de 'Margarita' não enxertadas.CD-ROM.
