A three-year follow-up of psychiatric morbidity in urban and rural primary care.

Follow-up by examination of medical and psychiatric records was carried out on 357 patients with conspicuous psychiatric morbidity in two general practices three years after clinical and personality assessment using structured interview schedules. One practice was an inner-city urban one and the other was rural. Full follow-up data over the 3-year period was available for 301 patients (84.3%). After three years patients with personality disorder and those in the urban practice had greater morbidity, more contacts with all levels of the psychiatric service and more psychotropic drugs, particularly benzodiazepines. Despite this increased morbidity, the number of consultations with the general practitioner for psychiatric illness was no higher in the urban group and those for medical illness were significantly higher in the rural one. The implications of the findings are discussed with particular reference to developments in community psychiatric care.

Personality disorder in perspective.

Personality disorders have for many years been on the fringe of psychiatry, with considerable doubts expressed about the usefulness, implications and validity of the concept. It is argued here that developments in the past few years have brought personality disorders into the mainstream of psychiatric practice. In particular, the recognition that personality function can be separated usefully from clinical symptoms, and that both mental state and personality can be disordered simultaneously, has led to better assessment and understanding. Advances in the classification, epidemiology, treatment and prognosis of personality disorders show that these conditions are common, extensive in their pathology, and cause much suffering. They cannot be ignored or dismissed as peripheral to psychiatry for they are an essential part of good psychiatric practice.

Identification of intrauterine growth retardation among low birth weight preterm infants.

This study describes an attempt to define intrauterine growth retardation low birth weight preterm infants by comparing reference standards for intrauterine growth in weight, length, and head circumference on their variability across ethnic groups and cities, and on their specificity in independently classifying infants as short, thin, or having small heads. The sample consisted of 985 inborn preterm low birth weight infants enrolled at eight participating sites in a randomized clinical trial using uniform sampling criteria. When gestational age was used as the reference standard, striking differences were found by ethnicity and site in the prevalence of low weight infants at birth. These differences, as well as the potentially false overlap of classification, were attenuated when the use of gestational age as a reference standard was used only for birth length, while length itself was used (as an alternative to gestational age) as the reference standard for birth weight, and weight was used as the reference standard for head circumference. These results raise questions about the use of gestational age as the primary or only reference standard in assessing weight and head circumference at bith.

Immune function in patients treated with phenytoin.

Multiple immunologic side effects have been ascribed to phenytoin. Numerous reports in the literature discuss the possible cellular and humoral abnormalities that appear to be present in patients given phenytoin. The most consistent finding is a reduction in serum IgA found in up to 20% of patients. To resolve some of the conflicting studies on cellular immune status, 191 patients taking phenytoin were evaluated initially with an serum IgA determination, and then further immune studies were done on the 11% with IgA values lower than two standard deviations below the mean. Data collected included total lymphocyte counts, lymphocyte population studies, and responses to in vitro mitogen stimulation. Only 2 of 191 patients had serum IgA values less than 5 mg/dL, which is an incidence not significantly different than that in the population at large. The patients with decreased serum IgA values did not have an increased incidence of autoimmune phenomena, allergic disorders, gastrointestinal manifestations, or recurrent upper respiratory tract infections. Their cellular immune status showed no significant variations from control values. Thus it appears that routine monitoring of patients on phenytoin with serum IgA determinations is of limited value, and the immunologic side effects of phenytoin are not expressed as a cellular abnormality.
