Neurofibromatoses are inherited tumour-suppressive disorders that are characterised by multiple neoplastic and non-neoplastic tumours. Neurofibromatosis type 1 is a common disorder with multiple neurofibromas with widespread complications. We here report a seven-year old boy presenting with first episode of seizure and multiple café-au-lait macules but neuroimaging revealed corpus callosal changes without any focal areas of signal intensities.

Child sexual abuse (CSA) includes abusive contact experiences, which habitually impact the victim’s whole life. This study aims to analyze the characteristics of six CSA experiences with physical contact, including penetration, in a representative sample of the Spanish population. Participants were 1071 Spanish adults (53% males; Mage: 45.37) who completed the Child Sexual Abuse Experiences Questionnaire. The victim’s age at the first episode, the perpetrator’s characteristics, and the number of times that each experience occurred were analyzed, taking into account gender differences. Results were reported for every experience independently. The most prevalent age at the first experience was from 6 years old onwards, but with differences in some experiences. The abuses usually happened more than once, committed by the same person. The most prevalent perpetrator is a male, although a female perpetrator is more prevalent in male victims. Most of the abuses were committed by an adult acquaintance, a strange adult, and other minors, with some gender differences. The implications of the results concerning every CSA experience are discussed, highlighting their value for future research and practice, the design of preventive programs, and early detection of CSA.

The aim of this study was to explore gender differences in social cognition in a sample of first-episode psychosis (FEP). An observational descriptive study was performed with 191 individuals with FEP. Emotion perception was assessed using the Faces Test, theory of mind was assessed using the Hinting Task, and attributional style was assessed using the Internal, Personal and Situational Attributions Questionnaire. No gender differences were found in any of the social cognitive domains. Our results suggest that men and women with FEP achieve similar performances in social cognition. Therefore, targeting specific needs in social cognition regarding gender may not be required in early interventions for psychosis.

AbstractBackground:Gender differences in symptomatology in chronic schizophrenia and first episode psychosis patients have often been reported. However, little is known about gender differences in those at risk of psychotic disorders. This study investigated gender differences in symptomatology, drug use, comorbidity (i.e. substance use, affective and anxiety disorders) and global functioning in patients with an at-risk mental state (ARMS) for psychosis.Methods:The sample consisted of 336 ARMS patients (159 women) from the prodromal work package of the EUropean network of national schizophrenia networks studying Gene-Environment Interactions (EU-GEI; 11 centers). Clinical symptoms, drug use, comorbidity and functioning were assessed at first presentation to an early detection center using structured interviews.Results:In unadjusted analyses, men were found to have significantly higher rates of negative symptoms and current cannabis use while women showed higher rates of general psychopathology and more often displayed comorbid affective and anxiety disorders. No gender differences were found for global functioning. The results generally did not change when corrected for possible cofounders (e.g. cannabis use). However, most differences did not withstand correction for multiple testing.Conclusions:Findings indicate that gender differences in symptomatology and comorbidity in ARMS are similar to those seen in overt psychosis and in healthy controls. However, observed differences are small and would only be reliably detected in studies with high statistical power. Moreover, such small effects would likely not be clinically meaningful.

BackgroundThe shape of the corpus callosum may differ in schizophrenia, although no study has compared first-episode with established illness.AimsTo investigate the size and shape of the corpus callosum in a large sample of people with first-episode and established schizophrenia.MethodCallosal size and shape were determined using highresolution magnetic resonance imaging on 76 patients with first-episode schizophrenia-spectrum disorders, 86 patients with established schizophrenia and 55 healthy participants.ResultsThere were no significant differences in total area across groups. Reductions in callosal width were seen in the region of the anterior genu in first-episode disorder (P<0.005). Similar reductions were seen in the chronic schizophrenia group in the anterior genu, but also in the posterior genu and isthmus (P = 0.0005).ConclusionsReductions in anterior callosal regions connecting frontal cortex are present at the onset of schizophrenia, and in established illness are accompanied by changes in other regions of the callosum connecting cingulate, temporal and parietal cortices.
