[Catatonia in childhood and adolescence - a brief review and case report].

The authors overview the clinical, epidemiological, pathophysiological and therapeutic aspects of catatonia in childhood and adolescence. They deal with the recent changes of the nosological position of the phenomenon, and emphasize the importance of specific therapeutic interventions.

Elevated Osteopontin and Interferon Gamma Serum Levels and Increased Neutrophil-to-Lymphocyte Ratio Are Associated With the Severity of Symptoms in Schizophrenia.

Inflammation and immune dysregulation could contribute to the pathogenesis of schizophrenia. Osteopontin (OPN) is a cytokine-like glycoprotein involved in inflammation and in modulating immune responses, and it can also directly modify the cytokine expression and survival of microglia. Furthermore, elevated gene expression of OPN in first episode psychosis has recently been described, but to date OPN level has not been investigated in schizophrenia. Imbalance of T-helper subtypes could also represent a vulnerability factor for schizophrenia. In this study, we analyzed the concentration of OPN, levels of cytokines associated with T-helper subtypes: interferon gamma (IFNy) for Th1, interleukin (IL)-10 for Th2, IL-8 for Th17, and neutrophil-to-lymphocyte ratio (NLR) in 22 patients with schizophrenia assessed for the intensity of their symptoms by the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression scale (CGI) scores. Serum OPN, IFNy, IL-10, and IL-8 concentrations were measured by ELISA kits and NLR was calculated from blood count. We found significant correlation between the level of OPN and PANSS-total and PANSS-general scores. IFNy level and NLR showed significant correlation with PANSS-total, PANSS-positive, PANSS-general, and CGI score. Among the measured markers antipsychotic therapy only had significant effects on NLR and OPN level, both of which were significantly reduced after long-term antipsychotic treatment. Our results indicate that elevated OPN and IFNy concentrations, and increased NLR are associated with severe symptoms in schizophrenia and suggest the importance of Th1 subtype in patients with high PANSS-positive and PANSS-general subscore. Significant correlation between NLR and PANSS scores strengthens the inflammation hypothesis of schizophrenia.

Adaptation and validation of the Hungarian version of the Yale Food Addiction Scale for Children.

Background Childhood obesity proves to be an important public health issue, since it serves as a potential risk factor for multiple diseases. Food addiction could also serve as an important etiological factor. As childhood obesity plays a serious issue also in Hungary, we aimed to adapt and validate the Hungarian version of the Yale Food Addiction Scale for Children (H-YFAS-C). Methods A total of 191 children were assessed with the H-YFAS-C and the Eating Disorder Inventory (EDI). The following psychometric properties were analyzed: internal consistency, construct validity, convergent, and discriminant validity. Results A good construct validity was revealed by confirmatory factor analysis (RMSEA = 0.0528, CFI = 0.896, χ2 value = 279.06). Question 25 proved to have no significant effect on its group and was removed from further analyses. The Kuder-Richardson 20 coefficient indicated good internal consistency (K20 = 0.82). With the use of the eight EDI subscales, a good convergent and discriminant validity could be determined. Food addiction was diagnosed in 8.9% of children. The mean symptom count was 1.7 ± 1.2 (range: 0-7). Females were more often diagnosed with food addiction than males (p = .016; OR = 3.6, 95% CI: 1.2-10.6). BMI percentiles were significantly higher in children with diagnosed food addiction (p = .003). There proved to be no correlation between age and the occurrence of food addiction. Discussion and conclusion Our results show that H-YFAS-C is a good and reliable tool for addictive-like behavior assessment.

[Yale Food Addiction Scale - review of literature].

INTRODUCTION: Food addiction is a condition presenting with a similar symptomatology to that of drug addiction, with an underlying individual sensitivity and special adaptation to certain foods, being consumed regularly. The concept of food addiction created one of the central issues in addiction research, owing to the pandemic spreading of obesity causing serious public health concerns. Development of an objective, standardized measuring tool of food addiction has become markedly necessary for both research and public health purposes. METHODS: Literature overview in the fields of food addiction and Yale Food Addiction Scale (1956-2016). RESULTS: For the establishment of food addiction diagnosis, the Yale Food Addiction Scale has become the most widely used method. It is an English questionnaire consisting of 25 questions, having been developed according to the 7 substance use disorder criteria in DSM-IV. The scale provides the possibility of diagnosis establishment, as well as measurement of food addiction severity. Development of the scale has given way to a number of new scientific results. The mean prevalence of food addiction is 19.7%, being more common in women, obese individuals, people >35 years and patients with already established eating disorders (binge eating disorder, bulimia). The most common symptom is the 'persistent desire or repeated unsuccessful attempts to quit'. A positive association has been recognized between food addiction symptomcount and the reward system dysfunction. CONCLUSION: The Yale Food Addiction Scale is a psychometrically valid, objective and standardized tool, being not only useful in addiction research but also helping in diagnosis establishment in clinical practice.
