An overview of relevant data sources in the former USSR for studies in demographic trends, aging and noncommunicable disease problems.

This article provides an overview of health data available in the former USSR. It is not all-inclusive in terms of chronic diseases covered or in details of data collection activities carried out. However, several broad conclusions can be drawn: There is a system of population and mortality data collection which covers the former USSR and which can be disaggregated to smaller administrative areas. The system is being exploited by population specialists, demographers, medical demographers and epidemiologists, both nationally and internationally, both for analytical purposes and as part of health monitoring systems. A national-level data-collection system for morbidity and disability, based on delivery of health services, is in place and is exploited by both health researchers and health planners. The shortcomings of such a health service-based statistical system are well recognized. Further standardization or calibration of measures of total and cause-specific morbidity and disability measures should be examined. A potential calibration tool is the 1988-1993 health examination and interview survey covering a representative (but highly clustered) sample of the former USSR population. The possibilities of greater standardization of measurement procedures used in this survey should also be investigated. In certain disease areas, e.g. cardiovascular diseases, cancer, rheumatic diseases and gerontology, clinical and epidemiological studies involving international collaboration have been carried out. This has resulted in the use of internationally accepted disease definitions, diagnostic procedures, and of clinical and laboratory standardization of demographic, social and biological measurements. Participation in multilateral or bilateral studies should be encouraged in research in disease areas where these types of programmes have not yet been instituted.(ABSTRACT TRUNCATED AT 250 WORDS)     

Fire in the operating theatre. Evacuation pre–planning may save lives

An operating theatre fire and the steps taken to deal with it are described; the difficulties encountered in evacuating anaesthetised patients are highlighted. Measures which might be taken to prevent recurrence of these problems, and recommendations on the institution of fire drills for the safety of patients and staff are given.     

FM sonography in diffuse liver disease: prospective assessment and blinded analysis

FM sonography - a signal-processing technique that uses frequency and phase information as well as amplitude data - shows promise in evaluation of patients with diffuse liver disease. In a prospective blinded review of 37 patients with biopsy-proved liver disease and 42 healthy volunteers, FM sonography was clearly superior to traditional amplitude-based (AM) sonography in distinguishing healthy from diseased subjects. Statistically significant differences were seen in accuracy (FM, 98.7%; AM, 84.8%), sensitivity (FM, 97.3%; AM, 70.3%), and negative predictive value (FM, 97.7%; AM, 78.8%). Our data also suggest that current FM sonographic techniques cannot differentiate among histologic findings associated with different hepatic parenchymal abnormalities. It is unclear, therefore, whether FM imaging can reduce the numbers of patients who require biopsy for diagnosis or the frequency of biopsy procedures in patients with known disease.     

Strengthening the role of primary health care in health promotion by bridging cultures in aboriginal health.

This paper advocates strengthening the role of primary health care in health promotion by bridging cultures in Aboriginal health. It encourages health care providers to consider the need for cross-cultural awareness in order to provide more effective health promotion. It suggests a number of strategies for overcoming structural barriers and individual factors which may hinder positive personal and professional cross-cultural communications.     

Systemic necrotizing vasculitis associated with childhood sarcoidosis

Childhood sarcoidosis is a rare disorder with protean manifestations. The case of a child with prolonged fever, hepatosplenomegaly, pancytopenia, and systemic necrotizing vasculitis manifesting as fever, rash and skin infarctions, digital pregangrene, and foot drop is reported. This is the first case of systemic necrotizing vasculitis reported in sarcoidosis. The fulminant course of the disease required treatment with intravenous pulsed cyclophosphamide and high doses of corticosteroids. The spectrum of vasculitis in childhood and adult sarcoidosis is reviewed.     

Detection of subclinical ascorbate deficiency in early Parkinson''s disease

From mid-October 1989 to mid-July 1990 all newly admitted residents to Bury Local Authority Residential Homes were comprehensively medically screened. In a series of 100 residents eight had early Parkinson's disease (six of them hitherto undiagnosed). Seven showed evidence of Vitamin C deficiency. Of the seven showing evidence of deficiency, four suffered from early Parkinson's disease. Of the 93 without evidence of Vitamin C deficiency only four had Parkinson's disease. This indicates a significantly higher prevalence of Parkinson's disease in the group with Vitamin C deficiency (P less than 0.001 using Fisher's exact).     

Closed-Chest Cardiopulmonary Bypass and Cardioplegia: Basis for Less Invasive Cardiac Surgery

Background. We developed a method of closed-chest cardiopulmonary bypass to arrest and protect the heart with cardioplegic solution. This method was used in 54 dogs and the results were retrospectively analyzed.

Methods. Bypass cannulas were placed in the right femoral vessels. A balloon occlusion catheter was passed via the left femoral artery and positioned in the ascending aorta. A pulmonary artery vent was placed via the jugular vein. In 17 of the dogs retrograde cardioplegia was provided with a percutaneous coronary sinus catheter.

Results. Cardiopulmonary bypass time was 111 ± 27 minutes (mean ± standard deviation) and cardiac arrest time was 66 ± 21 minutes. Preoperative cardiac outputs were 2.9 ± 0.70 L/min and postoperative outputs were 2.9 ± 0.65 L/min (p = not significant). Twenty-one-French and 23F femoral arterial cannulas that allowed coaxial placement of the ascending aortic balloon catheter were tested in 3 male calves. Line pressures were higher, but not clinically limiting, with the balloon catheter placed coaxially.

Conclusions. Adequate cardiopulmonary bypass and cardioplegia can be achieved in the dog without opening the chest, facilitating less invasive cardiac operations. A human clinical trial is in progress.     

Intravenous feeding with medium chain triglycerides. Effect on blood gases and the complement system in critically ill patients

Critically ill patients are usually in a catabolic state and may require total parenteral nutrition; this often includes lipid emulsions. Any adverse effects of constituents on pulmonary function, white cell function or the haemocoagulation system could have disastrous consequences in such patients. We have investigated the effects of a new intravenous lipid preparation containing medium chain triglycerides, which, in severely ill malnourished patients are theoretically a preferable energy source to conventional drug chain triglycerides. In a pilot study 17 critically ill patients whose lungs were artificially ventilated were given this lipid emulsion; no adverse effects were observed. Arterial oxygen and carbon dioxide tensions, ratio of inspired oxygen fractional concentration to arterial oxygen tension, platelet and white cell counts all remained constant and the complement system was not activated.
