Abstract Background: Thoughts about suicide are quite common in adolescent. While such thoughts can be caused by many reasons, the most well-known of these are mood disorders. There are studies related to coexistence of thyroid pathologies and mood disorders in adult. Objectives: In this study, we aimed to investigate the difference of thyroid hormone levels in between adolescents with suicide attempt history and normal population. Methods: The study was prospective and was designed as a case-control study. Demographic characteristics of the patients were obtained and Serum fT3, fT4 and TSH levels were examined. Results: 222 cases were included in the study, including 101 cases and 121 controls. As for TSH levels, the mean serum levels of the whole group was 1.96 ± 1.08 mU/L, while the mean serum levels of the control group was 2.33 ± 1.5 mU/L and the mean serum levels of the case group was 0.50 ± 0.3 mU/L which revealed that the mean serum levels of the case group was significantly lower (p<0.01). Conclusion: It was found that serum TSH levels were significantly lower in case group than control group and the individuals with subclinical hyperthyroidism had more suicide attempts than the ones in control group.

Abstract Introduction: this article examines a boy who was diagnosed with anorexia nervosa at eight years old. Pediatricians and family physicians encountered difficulties during the diagnosis and treatment stages due to the fact that early onset of the disease is rare. Case report: a boy aged eight years and four months presented with bradicardia, malnutrition and dehydration as far away from the preliminary diagnosis of anorexia nervosa investigated for possible organic pathologies at the pediatric ward. Finally, he was diagnosed with early-onset anorexia nervosa and anxiety disorder based on the Diagnostic and Statistical Manual of Mental Disorders 5. Discussion: the case highlights two important points. First, this case report demonstrates a limited awareness of anorexia nervosa and of a psychosomatic or psychiatric origin of weight loss in children among physicians. Second, disrupted eating behaviors and mood changes may be predicting factors for the development of full-blown anorexia nervosa.

Resumen Introducción: se presenta el caso clínico de un niño diagnosticado de anorexia nerviosa a los 8 años. Tanto los pediatras como los médicos de familia tuvieron problemas durante el diagnóstico y en el tratamiento debido a que su aparición a tan corta edad es poco frecuente. Caso clínico: un varón de ocho años y cuatro meses ingresó por bradicardia, desnutrición y deshidratación en un hospital pediátrico. Tras el despistaje de un origen orgánico, se diagnosticó de anorexia nerviosa y trastorno de ansiedad según DSM-5. Discusión: el caso pone de relieve dos aspectos. El primero, demuestra la atención limitada que prestan los médicos a un origen psicosomático o psiquiátrico, incluyendo la anorexia nerviosa, en una pérdida de peso en un niño. El segundo, que una alteración en la conducta alimentaria acompañada de cambios de carácter pueden ser factores predictores del desarrollo de un cuadro de anorexia nerviosa florido.
