Fluid milk processing costs: current state and comparisons.

An economic-engineering model is used to derive the theoretically minimum cost of processing and distributing fluid white milk for the state of Maine. This model represents a state-of-the-art milk processing facility and is used to evaluate three questions: 1) the components of total processing costs; 2) whether the cost of milk processing declines with increasing plant size; and 3) the minimum processing volume to financially justify inplant blow-molding technology. The model indicates that significant savings in per-container processing costs can be achieved by increasing plant size. However, distribution costs, related to the geographical distribution of consumer demand and plant location in the state of Maine do not favor large centralized plants. In addition, this model is compared with results published in 1993 to evaluate cost trends over a 7-yr period. The model indicates import shifts to more technologically advanced processing equipment and a dramatic increase in labor costs. Overall, processing costs have risen 2.9% annually above the rate of inflation. Dairies that are unable to respond to increased labor costs through capital investment and expansion will likely find it more difficult to remain competitive in the milk processing industry.

Coronary risk factors, knowledge and beliefs in 'blue collar' men attending general practice.

OBJECTIVE: To describe risk factors, dietary knowledge and beliefs in Australian-born males of low socio-economic status (SES) in relation to coronary heart disease. METHODOLOGY: Cross-sectional prevalence survey of 180 (99.7% of 185) selected attenders at a community health centre with a high proportion of low SES residents in Melbourne. RESULTS: Mean BMI and prevalence of obesity and smoking were higher than in national sample; age-weighted serum cholesterol somewhat lower. A majority believed that their diets were unhealthy and would continue to be so despite high perceived susceptibility to CHD. Seventy-two per cent wanted more dietary information and GPs were the most commonly nominated preferred source for this information. CONCLUSION: GPs have an important role in targeting this 'at risk' group in order to address the knowledge gaps and misconceptions identified in the study and to encourage appropriate behaviour and risk factor modification.

Shared obstetric care: the general practitioner's perspective.

Shared obstetric care between hospital and general practitioner (GP) is being developed in several States in Australia as an alternative model of care for pregnant women in the public hospital system. The aim of this study was to determine the attitudes of participating GPs to the shared obstetric care programme at the Royal Women's Hospital, Melbourne. Fifty GPs were randomly selected, and face to face individual interviews were conducted using qualitative methods. GPs feel that the continuity of care they can provide during pregnancy and the postpartum is a very important and valuable aspect of their role as shared care providers. They are generally satisfied with the programme at the Royal Women's Hospital but some suggest that communication between the hospital and the GP should be improved. There was significant interest in being involved in deliveries in shared care programmes in the future and GPs question the appropriateness of the diploma of obstetrics as the only acceptable qualification for shared care.

Angiogenesis after hepatic arterial occlusion in liver transplant patients.

The authors describe 10 liver transplant recipients who developed occlusion of the hepatic artery or aortic conduit. Since all potential collateral arterial supply to the transplant is severed at hepatectomy, hepatic artery occlusion is usually a catastrophic event that necessitates repeat transplantation. Four patients died within 8 weeks of transplantation. The remaining six developed spontaneous arterial liver revascularization. This phenomenon is believed to be an example of neovascularization through angiogenesis. Radiologic studies, particularly duplex sonography and angiography, were helpful in the evaluation of transplant vascular integrity. The tissues of the omentum and the mesentery have known angiogenic ability. The authors postulate that in transplantation techniques in which these tissues are placed close to the transplanted liver (eg, Roux-en-Y choledochojejunostomy), the omental and mesenteric tissues may be the source of neovascularity.

Burn depth evaluation with fluorometry: is it really definitive?

Clinical evaluation of burn depth soon after injury is subjective, based on gross visual assessment. Previous investigators have quantified this process using fluorometry. Their studies show fluorescein levels in full-thickness burns to be far below control levels and partial-thickness burns to be about 60% of nonburned skin. In both rat and human models, 59 burn sites (eight rats) and 37 burn sites (seven patients) were assessed. Readings were taken for three hours on the rats and one hour on the patients during the first 48 hours, and the procedure was repeated for five days postburn. Maximum values during these periods were determined for burn and nonburn sites, and background levels were subtracted from these values. The rate of fluorescein uptake and the peak times for burn and nonburn sites were then compared. Actual depth of burn was determined by whether or not healing had occurred. The results showed no significant difference between partial-thickness and full-thickness burns using fluorometry, as standard deviations in both models for both depths of burn were large. Therefore, fluorometry did not provide a definitive evaluation of burn depth. These results differ from those reported by previous investigators.
