Digital arthrography in the evaluation of painful joint prostheses.
Digital arthrography was accomplished in 16 patients who had painful prostheses. In each instance, resulting arthrographic abnormalities were compared with those apparent on subsequent overhead radiographs. Results indicate the potential value of the digital technique in this clinical setting. The examination is easy to perform and rapid, and allows the examiner to view the changing images in the subtraction mode. Image manipulation and enhancement are also possible.

CT analysis of proximal femoral trabecular pattern simulating skeletal pathology.
The proximal femoral trabecular pattern was studied in 20 patients, six cadavers, and 20 macerated specimens using plain film radiography and CT. A distinctive pattern of increased radiodensity in the proximal femur is described in patients and specimens with osteoporosis and osteoarthritis. The appearance is similar to that of an enchondroma or bone infarct. This pattern may be explained by biomechanical principles and is created by unmasking or hypertrophy of preexistent, reinforcing trabeculae. Confusion with osseous pathology can be avoided if the radiologist is aware of this pattern.

MR imaging in tarsal tunnel syndrome.
Magnetic resonance imaging was used to demonstrate the normal anatomy of the tarsal tunnel in two volunteers and to evaluate 33 feet in 27 patients with tarsal tunnel syndrome. The tarsal tunnel is a fibroosseous channel extending from the ankle to the midfoot, through which the medial tendons and the posterior tibial neurovascular bundle pass. Tarsal tunnel syndrome is a compression neuropathy of the posterior tibial nerve or one of its branches and may be caused by a variety of pathologic lesions. Magnetic resonance imaging demonstrated a mass lesion in five feet, dilated veins or varicosities in eight feet, fracture or soft tissue injury in five feet, fibrous scar in two feet, flexor hallucis longus tenosynovitis in six feet, and abductor hallucis muscle hypertrophy in one foot. Six feet were normal on MR imaging. The findings of MR imaging were confirmed in 17 of 19 patients that went to surgery. Magnetic resonance is useful for localizing lesions within the tarsal tunnel and for determining the lesion extent and relationship to the posterior tibial nerve and its branches.

Calculating nursing turnover in NSW.
A study of nursing staff turnover is being carried out by the Nursing Research Team from the Riverina-Murray Institute of Higher Education for the New South Wales College of Nursing and the New South Wales Department of Health. The general aim of the study is to provide information about the annual rate of loss of registered nurses from public hospitals and licensed private hospitals in NSW. This paper provides background details about the project and recent attempts to understand the problem of nursing staff turnover. Brief mention is made of Australian and overseas literature and recent calls for methodological and conceptual precision in calculation nursing turnover. Reference is made to 'Nursing Turnover Indices' and other statistical descriptors used to guide this research.

The Wernicke-Korsakoff syndrome: a reappraisal in Queensland with special reference to prevention.
The Wernicke-Korsakoff syndrome occurs most frequently in alcoholic patients when they become thiamin deficient. First admissions to psychiatric units with the chronic component of this syndrome, Korsakoff's psychosis, peaked in Queensland in 1975-1976. The fall in hospital admission rates since this time could relate to a decline in per-capita alcohol consumption in Australia, or to more awareness of the thiamin needs of drinkers. Alternatively, the improvement may be illusory: although many cases of Wernicke's encephalopathy are being diagnosed, many of these patients are not receiving psychiatric assessment and treatment, perhaps because admission to psychiatric hospital beds is more difficult than it was formerly. Patients who are diagnosed as having Korsakoff's psychosis fare badly in the community, and have a greatly increased mortality rate than do such patients in hospital. Optimal care for such patients is necessarily costly of medical resources. Of available preventive measures, evidence is presented to support the fortification of beer with thiamin and the provision of community educational programmes. The fortification of flour with thiamin may have little impact on the thiamin-deficiency syndromes that arise in problem drinkers in Queensland.
