Objective: Although the fifth Body Mass Index (BMI) percentile is the Diagnostic and Statistic Manual of Mental Disorders -5 weight cut-off criterion to diagnose anorexia nervosa (AN) in children and adolescents, its validity has not been proved, and the 10th percentile value is often applied. We aimed to investigate the diagnostic validity of these weight cut-offs., Method: We compared general and eating-disorder (ED) specific psychopathology in 380 adolescents with AN or atypical AN. They were grouped first with respect to the fifth BMI percentile and then with respect to the 10th BMI percentile and differences between groups were analysed. Network analyses on psychopathological symptoms were also conducted., Results: Adolescents with BMI above the fifth and the 10th percentile reported more severe ED specific symptomatology compared to those with BMI below these cut-offs. No significant differences emerged between groups neither in general psychopathology nor in the network structure of psychopathology., Conclusions: The fifth BMI percentile does not discriminate psychopathology severity in adolescents with AN. From the psychopathology perspective, our findings suggest that adolescents with atypical AN deserve the same clinical and research attention as those with full AN. Future studies are needed to identify a more accurate definition of underweight in adolescents., (© 2020 Eating Disorders Association and John Wiley & Sons Ltd.)

Objective: Research evidence suggests the need to identify treatments based on a more precise characterization of psychopathology and psychiatric comorbidity in anorexia nervosa. Network analysis provides a new method to conceptualize psychopathology. We use this approach to investigate the relationships between eating disorder and general psychiatric symptoms in adolescents with anorexia nervosa., Methods: Four-hundred and five adolescents with anorexia nervosa and illness duration less than 3 years were consecutively recruited from those admitted to inpatient treatment. They completed the following questionnaires: the Eating Disorder Inventory-3, the Multidimensional Anxiety Scale for Children, the Children's Depression Inventory, and the Youth Self Report. A network analysis was conducted, including eating psychopathology measures, anxiety and depressive symptoms, and obsessive-compulsive and post-traumatic stress problems. We employ a novel approach, the bridge function, to identify symptom clusters., Results: Depression symptoms and personal alienation were the nodes with the highest centrality in the network, followed by asceticism, post-traumatic stress problems, drive to thinness, low self-esteem, and anxiety physical symptoms. Three symptom clusters (relative to eating disorder psychopathology, self-esteem problems, and internalizing difficulties) were identified. Depression symptoms, personal alienation, low self-esteem, and interoceptive deficits showed the highest bridge centrality. Besides eating disorder core symptoms, negative affect and internalizing symptoms seem to contribute to anorexia nervosa psychopathology independently from illness duration effects., Discussion: These findings suggest that anorexia nervosa is characterized by a broad psychopathological spectrum rather than the mere eating disorder core symptoms, confirm the need to re-conceptualize psychiatric comorbidity in this disorder, and provide intriguing diagnostic and therapeutic implications., (© 2019 Wiley Periodicals, Inc.)

We report the case of a 16-year-old boy with 'igloo-like prepuce' and hypospadia, successfully treated by asymmetrical antero-posterior postectomy. Histopathological examination consisting of classical microscopy, immuno-histochemistry and electronmicroscopy of the surgical material provided insights into the etiopathogenesis of this rare disease.

Background: p27KiP1 is a cyclin-dependent kinase inhibitor and is a potential tumor suppressor gene. Reduced expression of p27Kip1 is a powerful negative prognostic marker in primary lung, breast, colon, bladder, and prostate carcinomas. In the current study, the prognostic value of p27Kip1 in gastric cancer was evaluated and compared with other histopathologic parameters and p53 expression., Methods: p27Kip1 and p53 protein expression were determined by immunohistochemistry in 96 gastric carcinomas. The tumors were from a low incidence population and were selected for the absence of lymph node involvement., Results: Reduced expression of p27KiP1 (< or = 50% positive cells) and nuclear p53 accumulation (> 30% positive cells) were observed in 67 (69.8%) and 9 (9%) tumors, respectively, and were not related to either the pT category or tumor histology. Kaplan-Meier analyses revealed a significant impact on survival by p27Kip1 (P = 0.0001 by log rank test), p53 (P < 0.0001) expression, and the pT category (P < 0.0001). On multivariate analysis, reduced p27Kip1 protein expression was the strongest independent predictor of reduced survival (P = 0.005; relative risk = 3.348) out weighing the pT category (P = 0.010; relative risk = 2.257) and p53 overexpression (P = 0.016; relative risk = 2.618)., Conclusions: These data indicated that immunohistochemical detection of p27Kip1 could help to identify gastric carcinoma patients who are at high risk of death, even in the absence of lymph node involvement, and who might benefit from an adjuvant treatment following surgery.
