This study of 106 preadolescent psychiatric inpatients, 101 preadolescent psychiatric outpatients, and 101 preadolescent nonpatients examined the prevalence of psychiatric disorders and co-occurrence of psychiatric diagnoses. The inpatients and outpatients had significantly more co-occurring diagnoses than the nonpatients. For a given diagnosis there are varying frequencies of co-occurring disorders. The similar structure and prevalence among co-occurring diagnoses in this sample of children fit a circumplex model in which variation among disorders appears to be continuous in the form of a closed circle.
This report explores the interface between psychiatry and the DSM-III, arguing that philosophy and psychiatry are of value to one another. Three trends within philosophy are delineated--positivism, hermeneutics, and a synthetic position. These trends are applied to the DSM-III and to specific issues in psychiatric nosology such as the definition of mental disorder, the question of establishing boundaries between different psychiatric disorders, and the differentiation of organic and functional disorders. It is argued that while nosologists often think of themselves along positivist lines, and are often criticized by hermeneutic thinkers for just these assumptions, a synthetic view accounts best for how psychiatric science works. It is concluded that philosophy undergirds psychiatric nosology, while psychiatric nosology raises a series of philosophical questions.
The number of patients with mixed neurologic and psychiatric disturbances is large. The psychiatric disturbances are often atypical in presentation and fit poorly into standard psychiatric nomenclature. They can be difficult to treat using standard psychopharmacologic approaches. This report reviews the impact of brain dysfunction on the use of conventional and nonconventional psychotropic agents in this mixed population.

Liaison psychiatry is an area fraught with diagnostic problems due to the complex overlap between psychopathology and physical illness. The worst difficulties arise where patients also exhibit maladaptive behaviour such as deliberate self harm. In these situations a number of professionals may become involved including physicians, psychiatrists and social workers. As the level of complexity of a case increases an accurate formulation and diagnosis become essential. The International Classification of Diseases 10th revision (ICD-10) in its 1986 draft is currently being field tested. Chapter V (F) 'Mental, Behavioural and Developmental Disorders, is a descriptive clinical psychiatric classification, which will soon be incorporated into a multi-axial schema. This draft classification was used to make a diagnosis for 50 consecutive referrals to a liaison psychiatrist working in a large District General Hospital. This report assesses the applicability of ICD-10, V (F) in liaison psychiatry, and also comments on the characteristics of this group of patients. This leads to a discussion of the requirements for the other axes that would be needed to produce a multi-axial schema capable of allowing complex problems to be accurately formulated.

Recent research has further confirmed the significant incidence of undiagnosed physical illness in patients presenting psychiatric symptoms. Such research has generally involved psychiatric inpatient or outpatient populations. As a liaison psychiatrist in a general hospital, the author defines two especially high-risk groups for such missed diagnoses and emphasizes the fact that psychiatric symptoms are not illness specific. An approach to the clinical evaluation of such patients is discussed, mentioning the inherent medicolegal implications.
Patients with coexistent medical and psychiatric disorders, when both require acute-level care, are managed only with considerable difficulty in traditional hospital settings. A unit designed to offer such patients comprehensive care is described, its clinical and educational advantages discussed, and the essential administrative features of its operation identified. Since very few comparable units exist at the present, our model is offered in the hope of encouraging and assisting their future development. In view of current trends in the evolution of our field, this type of unit may well represent the advancing edge of inpatient psychiatry.
A literature review and pilot investigations reveal that (ward-) management consultation-liaison (C/L) psychiatry recommendations are infrequent and unsystematically used. Furthermore, the communication with the operational group as defined by Meyer and Mendelson is not sufficiently activated. The major focus of the consultation is the first contact, but follow-up is infrequent. With the exception of biologic recommendations and disposition, chart notes by psychiatric consultants do not sufficiently specify the actions to be taken by the ward staff in a general hospital. A schema for the systematic organization of the intervention was developed. A checklist of operationalized C/L interventions is reported. This combination provides a tool for the systematic use of strategic ward management and discharge recommendations. Its basic structure is currently integrated in MICRO CARES [Hammer et al, SCAMC]. The impact on clinical care, education, and research is described.
The prevalence of physical illness was determined in a population of geriatric patients on a unit of psychiatric inpatients. Ninety-two percent of the 95 patients were found to have one or more significant medical problems. The average number of medical conditions was 1.9. The disorders were classified according to affected organ system.
