Myeloproliferative and lymphoproliferative disorders in Tasmania, 1972-80: occupational and familial aspects.

All cases in a population-based series of myeloproliferative and lymphoproliferative (LP) disorders diagnosed in usual residents of Tasmania between 1972 and 1980 were asked for occupational histories and the occurrence of similar diseases in their close relatives. Occupational risks were observed for males who had farmed, mined, or worked in foundries and for women who had farmed or had been hairdressers. For individual diagnoses, the risk to farmers was seen to vary with age at diagnosis, sex, and region. With regard to familial risks, the LP and MP groups seemed to breed true, relatives being affected with a disorder from the other group not more often than would be expected by chance. The risks were of two kinds: Those to siblings and that between parent and child, particularly between mother and son. Occupational risks for the familial cases were limited to farming particularly in males diagnosed at 65 years of age or older. Females possessed elevated risks for the LP group only, and their highest relative risk was for those diagnosed before age 65. This evidence suggests that familial clustering of these disorders partly may be due to common environmental exposures in males from rural kindreds.

Immunological types of lymphoproliferative disorders in a cohort: a 4-year study.

Immunological testing of malignant cells and serum from most cases of lymphoproliferative disorders (LPD) allows the cell type to be characterised as of B, T or "null" lymphocyte origin. Regional differences in the incidence of neoplasms of these types have been reported. Furthermore, most published series have drawn cases from referral institutions rather than the general population. In order to determine the true incidence of a cohort we surveyed an entire population, that of Tasmania, an island state of Australia with a population of 410,000, during a defined period, the years 1977-1980 inclusive, for the occurrence of LPD. A total of 248 cases was discovered, made up of 133 cases of non-Hodgkin's lymphoma (NHL), 30 of chronic lymphocytic leukaemia (CLL), 18 of acute lymphoblastic leukaemia (ALL), 54 of multiple myeloma (MM), eight of macroglobulinaemia (MGA) and five others. We identified B lymphocytes by the presence of surface membrane immunoglobulin (Smlg) and their ability to rosette with mouse red blood cells, and T lymphocytes by their ability to rosette with sheep red blood cells. Laboratory testing was performed in 201 (81%) of the cases and characterisation of the cell of origin as of B, T or "null" type was successful in 158 (64%). Of these 158, 136 (86%) were B, 4 (3%) T, and 18 (11%) "null". On B cell subtyping by heavy and light chain lg analysis the Tasmanian series, compared with other reports, had an apparent paucity of B-CLL, MM and MGA of lambda subtype (57 k to 12 lambda, k:lambda ratio 4.8:1) and an unusual incidence of B-CLL with the double lg heavy chain combination M+G. Surveys of this type may help to point to environmental or other factors important in the aetiology of LPD.

Role of alcohol in the aetiology of hypertension.

Hypertension is a common condition facing medical practitioners on a day-to-day basis, yet much is to be learnt regarding its cause. Excess alcohol intake has been recognized by clinicians as a causal factor on an anecdotal basis for many years now. Little evidence for this has been provided from statistical analysis of formal studies. On this basis, a study was undertaken in a population of 85 adult males to see if any correlations could be drawn between alcohol intake and standard blood pressure readings, taking into account as many other variables as possible which may contribute to blood pressure, such as age, body weight and smoking habits. In this study, a statistically significant relationship between alcohol intake and blood pressure is demonstrated, indicating a need for further investigation in this field.

Lymphoproliferative and myeloproliferative disease in Tasmania.

Tasmania, an island state of the Australian Commonwealth with a population of 400,000 of predominantly Anglo-Saxon heritage, has relatively centralized oncology services. A study was undertaken of all patients known in December 1971 and of all new cases diagnosed since January 1972 with all forms of leukemia, Hodgkin's disease, non-Hodgkin's lymphoma, myeloma, and other myeloproliferative and lymphoproliferative disorders. Data were obtained with respect to lifetime residential and occupational history, schools attended, and known familial cases of any of the myeloproliferative and lymphoproliferative disorders.

Palliative care and melanoma: the care of the patient with progressive disease.

The World Health Organization has taken the lead in recent years in encouraging an appropriate focus on palliative care which includes but goes beyond terminal care. Comprehensive care of patients with advanced progressive disease requires increased emphasis, with adequate resources. Management of major symptoms is a crucial component of such a care program and requires the application of recent advances in palliative therapeutics (notably but not only good quality pain management), whether or not direct antitumor strategies are being continued. The choice of treatment approaches must be related to the patient's personal priorities.
