Thyroid dysfunction after mantle irradiation of Hodgkin's disease patients

Thyroid dysfunction can develop in patients with Hodgkin's disease who are treated with mantle irradiation. During the period 1970-89, the records of 320 patients who received mantle irradiation and who had thyroid function tests (TFT) were retrospectively reviewed. The median age was 30 years (range, 7-69 years). The median mantle and thyroid dose was 36 Gy (range, 30-40 Gy) and 39.8 Gy (range, 32-65 Gy), respectively. Overall thyroid dysfunction was present in 39% of the patients. Clinical hypothyroidism was seen in 10% and biochemical hypothyroidism was noted in 25%. Hyperthyroidism was found in 4% of patients. Thyroid nodules had developed in six patients (2%), of which those in four patients were malignant. Age, sex, histological subtype, stage of disease, dose, lymphangiogram and treatment with chemotherapy were not significant factors in the development of thyroid dysfunction. The narrow dose range prevented adequate analysis of dose effect. The results indicate that the incidence of thyroid abnormalities is high enough to warrant regular TFT assessment with pre-irradiation levels and follow-up testing for life because the development of abnormalities can occur many years later. Thyroid examination should form part of the routine follow-up examination and any abnormality should be promptly investigated.     

Embedding Socio-Behavioral Frameworks in Community Rehabilitation: Evaluation of a Service Change Program

Background: Paradigms which emphasize the social determinants of health and client self-management, and approaches which promote health behavior change, are rarely operationalized within rehabilitation settings. The aim of this study was to investigate the processes required for this model of care change within an existing allied health community rehabilitation service. Methods: The service change program consisted of training elements in the areas of the social determinants of health, client self-management and health behavior change techniques as well as associated operational changes to reflect this paradigm shift. Results: The training packages implemented appear to have improved staff knowledge and skills within these socio-behavioral areas. Clinicians self-reported improvement with client care; however, these changes were not reflected in the chart audit. Conclusions: Clinician training is required to build both knowledge and skills in the areas of the social determinants of health, client self-management and health behavior change principles. In addition, clinicians should be equipped with frameworks to assist with operationalizing these principles.
