Consultation psychiatry plays an important role in developmental medicine. The concept of consultation psychiatry in general medicine includes diagnosis, support and assistance in solving psychiatric, psychological or psychosocial problems of the patient. Child psychopathology, which results from the interaction of biological and psychosocial factors, may be manifested by categorical psychiatric disorders, which may coexist with somatic diseases, and may also be a secondary reaction in response to other illnesses. The disorganisation of behaviour in patients at the developmental period may also result from the response to the disease or hospitalisation. On the other hand, mental disorders can significantly hamper the treatment of somatic diseases. The objective of this study was to determine the spectrum of psychopathology and to analyse the reasons for psychiatric consultation on the multidisciplinary wards of the University Children’s Teaching Hospital. During 9 years, 741 psychiatric consultations were carried out. The results obtained indicate that anxiety, stress-related and somatoform disorders were the most common category of mental disorders (30.5%) observed in consulted girls (30.0%) and boys (31.5%). Emotional and conduct disorders were found in 22.8% of the consulted children. There was a significant difference (p = 0.02) between boys (31%) and girls (18.3%). Eating disorders were identified in 17% of the examined group. This category, which includes anorexia nervosa, atypical anorexia and bulimia, was significantly more frequently (p < 0.001) observed in girls (23.9%) than boys (3.6%). A refusal to eat (24.4%) was, next to deliberate intake of pharmacological agents (21.7%), the most common reason for psychiatric consultations in the examined group.
