IntroductionEating Disorders (ED) as Anorexia Nervosa (AN), Bulimia Nervosa (BN) and Binge Eating Disorder (BED) are severe and debilitating psychiatric diseases whose etiology is complex and still largely unknown. Several studies seem to suggest that serotonin could be involved and notably there are several associations with 5-HTTLPR polymorphism, especially with the S allele and the S/S genotype.ObjectivesThe purpose of this study is to evaluate if an association between ED and 5-HTTLPR (especially the S allele frequency) can be shown.Material and methodsA group of about 100 subjects attending the eating disorders unit of Ancona will be tested. Their DNA will be taken and the frequency of the S allele will be compared with a control subjects group negative for ED. Then, the ED group will be divided, according to the DSM-5 criteria, in 3 subgroups (AN, BN, BED) and potential differences will be evaluated.ResultsAt the moment, we are still collecting patients. According to other studies involving 5-HTTLPR, the S allele frequency in Italy is comparable with the European one, so there is reason to believe that an association could be found.ConclusionsSerotonin involvement in ED in literature is shown, but it still has to be completely expounded. Studies as this one could help in describing the etiology and the development of this disease.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Feeding and eating disorders are defined by persistent disturbance of eating (or behaviors related to eating) with subsequent changes in consumption or absorption of nutrition that are detrimental to physical health and social functioning. The following eating disorders are described in the DSM-5: anorexia nervosa, bulimia nervosa, binge eating disorder, pica, rumination disorder, avoidant/restrictive food intake disorder (ARFID), other specified feeding or eating disorder (OSFED), and unspecified feeding or eating disorder (USFED). ARFID, OSFED, USFED, rumination disorder, and binge eating disorder are new additions to the manual and are first described in the DSM-5. The DSM-5 also provides severity specifiers—mild, moderate, severe, and extreme—for the diagnoses of bulimia nervosa and anorexia nervosa. This review describes the eating disorders enumerated in the DSM-5 and provides information regarding their genesis and course. This review contains 8 tables and 79 references Key words: avoidant/restrictive eating disorder, binge eating disorder, DSM-5, eating disorder, other specified feeding or eating disorder, pharmacotherapy, pica rumination, psychotherapy, unspecified feeding or eating disorder

This chapter describes the diagnostic criteria used in clinical and research settings to define eating disorders and highlights important changes in the criteria introduced by DSM-5 in 2013. Emerging evidence suggests that the DSM-5 categories usefully capture a range of eating problems in need of clinical attention that were not well described in previous DSM editions. The chapter also reviews the characteristics of adolescents and young adults with eating disorders, their frequency in the general population, and their psychological comorbidities. Important medical complications associated with the disorders, especially among adolescents, are summarized, as well as approaches to their treatment. The chapter covers in greatest detail anorexia nervosa, bulimia nervosa, and binge-eating disorder.

Abstract Purpose: This study aimed to determine the changes in diagnosis that occur in making the transition from Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria in an adolescent medicine eating disorder program. Methods: During the months of September 2011 through December 2012, a data sheet was completed at the end of each new outpatient eating disorder evaluation listing the patient’s gender, age, ethnicity, weight, height, DSM-IV diagnosis, and proposed DSM-5 diagnosis. Distributions were calculated using the Mann-Whitney and Wilcoxon rank sum analyses to determine differences between diagnostic groups. Results: There were 309 patients evaluated during the 16-month period. DSM-IV diagnoses were as follows: anorexia nervosa, 81 patients (26.2%); bulimia nervosa, 29 patients (9.4%); binge eating disorder, 1 patient (0.3%); and eating disorder not otherwise specified (EDNOS), 198 patients (64.6%). By contrast, DSM-5 diagnoses were as follows: anorexia nervosa, 100 patients; atypical anorexia nervosa, 93 patients; avoidant/restrictive food intake disorder, 60 patients; bulimia nervosa, 29 patients; purging disorder, 18 patients; unspecified feeding or eating disorder, 4 patients; subthreshold bulimia nervosa, 2 patients; subthreshold binge eating disorder, 2 patients; and binge eating disorder, 1 patient. Conclusion: Almost two thirds (64.6%) of the 309 patients had a diagnosis of EDNOS based on the DSM-IV criteria. By contrast, only four patients had a diagnosis of unspecified feeding or eating disorder based on the DSM-5 criteria. These data demonstrate that the goal of providing more specific diagnoses for patients with eating disorders has been accomplished very successfully by the new DSM-5 criteria.

This chapter addresses the pharmacotherapy of the eating disorders (EDs). Many persons with EDs receive pharmacotherapy, but pharmacotherapy research for EDs has lagged behind that for other major mental disorders. This chapter first provides a brief rationale for using medications in the treatment of EDs. It then reviews the data supporting the effectiveness of specific medications or medication classes in treating patients with anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other potentially important EDs, such as night eating syndrome (NES). It concludes by summarizing these data and suggesting future areas for research in the pharmacotherapy of EDs.

The epidemiology of eating disorders holds important clues for understanding factors that may contribute to their etiology. In addition, epidemiological findings speak to the public health significance of these deleterious syndromes. Information on course and outcome are important for clinicians to understand the prognosis associated with different disorders of eating and for treatment planning. This chapter reviews information on the epidemiology and course of anorexia nervosa, bulimia nervosa, and two forms of eating disorder not otherwise specified, binge eating disorder and purging disorder.

The aim of this study has been to investigate the dissociative phenomena and the difficulties related to perceive, understand and describe the proper ones and other people's emotional states in a sample of 53 patients with Eating Disorders. The recruited sample is made by 14 Anorexia Nervosa (AN) patients, 15 with Bulimia Nervosa (BN), 12 with Eating Disorder Non Otherwise Specified (EDNOS) and 12 with Binge Eating Disorder (BED). To all subjects was administred the Eating Disorder Inventory-2, the Dissociative Experiences Scale and the Scala Alessitimica Romana. In according with literature, we confirme the relationships among Eating Disorders, the dissociative phenomena and Alexithymia.
