Diagnostic outcome of patients referred to psychiatry with medically unexplained symptoms: a retrospective study

Objective: Medically unexplained symptoms (MUS) are commonly encountered in medical practice. In psychiatry; they are classified mostly as Somatoform Disorders and are often associated with anxiety and depression. The literature suggests that; in some cases; MUS may be ascribed to Somatoform Disorders when; fact; they are ""organic"" syndromes that are misdiagnosed. In developing countries; with fewer resources; MUS may be more difficult to assess. Method: We undertook a retrospective chart review to examine the demographics; referral pathway; management and diagnostic outcome of subjects (n = 50) referred to psychiatry with MUS over an 18 month period. Results: Subjects with MUS accounted for only 4.5of the total number of files reviewed. In only 38of cases did the final diagnosis in psychiatry concur with the referral diagnosis. In 28of cases a new ''organic"" diagnosis was made and in 72of cases a new psychiatric diagnosis was made. Subjects who were diagnosed with ""organic"" illness were seen fewer times prior to referral to psychiatry and were significantly older than other subjects. Conclusion: In developing countries like SA; a significant number of patients with MUS may have underlying ""organic"" illness; and most may have psychiatric disorders. Patients with MUS; especially older patients; should be more extensively investigated. Psychiatric referral of these patients is very appropriate."

A retrospective review of trends and clinical characteristics of methamphetamine-related acute psychiatric admissions in a South African context

Abstract Objective: Epidemiological studies indicate that methamphetamine (MA) abuse poses a major challenge to health in the Western Cape. The objectives of this study were to retrospectively assess the trends, clinical characteristics and treatment demand of MArelated admissions to a psychiatric ward in this region. Method: The clinical records of patients admitted to an acute psychiatric admission ward at Tygerberg Hospital from 1 January 2002 to 30 June 2002 and 1 January 2006 to 30 June 2006, were retrospectively reviewed. Admission numbers including those of adolescent and adult substance users were compared for both study periods. Study samples comparing demographic profile, admission status, length of stay, psychopathology, treatment requirements and referral pattern to other disciplines between MA users and non-users were collected for the 2006 period. Results: There was a significant (p <0.01) increase in adolescent substance user admissions between the study periods. A significant (p <0.01) increase in adolescent and adult MA user admissions was also noted. MA users were significantly (p = 0.04) younger than non-MA users, whilst the former presented mainly with psychotic features associated with aggression, requiring involuntary admission of an average of 8 weeks. MA users required significantly (p = 0.007) more benzodiazepines compared to non-MA users. Conclusion: Although MA use is relatively recent to the Western Cape, its adverse psychiatric effects and consequences have become a major challenge. These effects in both adolescent and adult patient populations and the associated impact on psychiatric services demand urgent intervention strategies as well as prospective study
