What price medical malpractice insurance?

The Medical Review and Advisory Board has been established as a committee of the Commission on Professional Welfare of the California Medical Association to make studies and recommendations toward solution of the growing problems of professional liability insurance and malpractice actions in California. The members of the Board are: Joseph F. Sadusk, Jr., Oakland, Chairman; Wilbur Bailey, M.D., Los Angeles, vice-chairman; Howard W. Bosworth, M.D., Los Angeles; H. I. Burtness, M.D., Santa Barbara; Paul W. Frame, Jr., M.D., Sacramento; Verne G. Ghormley, M.D., Fresno; Carl M. Hadley, M.D., San Bernardino; Joseph J. O'Hara, M.D., San Diego; William F. Quinn, M.D., Los Angeles; Rees B. Rees, M.D., San Francisco; and Bernard Silber, M.D., Redwood City; Mr. Rollen Waterson, 564 Market Street, San Francisco 4, is executive secretary, and Mr. Howard Hassard is legal counsel.     

A dry lab for medical engineers?

Post-operatory wound infections are a very uncommon finding after thyroidectomy. For these reasons international guidelines do not routinely recommend systemic antibiotic prophylaxis. The benefits of this antibiotic prophylaxis is not supported by clinical evidence in the literature. We have conducted a multicentric randomized double-blind trial on 500 patients who had undergone thyroidectomy for goitre or thyroid carcinoma. The 500 patients enrolled in the study (mean age 47 years) were randomized in two subgroups of 250 patients. 250 patients were treated with standard antibiotic prophylaxis with sulbactam/ampicillin 1 fl (3 gr.) 30 min before surgery. No antibiotic prophylaxis was instituted in the remainder 250 patients. Our RCT showed that prophylactic antibiotic treatment is not beneficial in patients younger than eighty years old, with no concomitant metabolic, infective and hematologic disease, with no cardiac valvulopathies, not under steroidal or immunosuppressive treatment, and not severely obese. Our study should be regarded only as a preliminary RCT, and should be followed by a study in which a larger number of patients should be enrolled so that statistically significant data can be obtained.     

Radiomics in radiooncology – Challenging the medical physicist

PurposeNoticing the fast growing translation of artificial intelligence (AI) technologies to medical image analysis this paper emphasizes the future role of the medical physicist in this evolving field. Specific challenges are addressed when implementing big data concepts with high-throughput image data processing like radiomics and machine learning in a radiooncology environment to support clinical decisions.MethodsBased on the experience of our interdisciplinary radiomics working group, techniques for processing minable data, extracting radiomics features and associating this information with clinical, physical and biological data for the development of prediction models are described. A special emphasis was placed on the potential clinical significance of such an approach.ResultsClinical studies demonstrate the role of radiomics analysis as an additional independent source of information with the potential to influence the radiooncology practice, i.e. to predict patient prognosis, treatment response and underlying genetic changes. Extending the radiomics approach to integrate imaging, clinical, genetic and dosimetric data (‘panomics’) challenges the medical physicist as member of the radiooncology team.ConclusionsThe new field of big data processing in radiooncology offers opportunities to support clinical decisions, to improve predicting treatment outcome and to stimulate fundamental research on radiation response both of tumor and normal tissue. The integration of physical data (e.g. treatment planning, dosimetric, image guidance data) demands an involvement of the medical physicist in the radiomics approach of radiooncology. To cope with this challenge national and international organizations for medical physics should organize more training opportunities in artificial intelligence technologies in radiooncology.     

Older Russian emigrés and medical care.

Although emigration from the former Soviet Union is dramatically increasing nationwide, little information has been reported on the medical problems of these emigrés. For older emigrés in particular, the medical realities of aging, in combination with cultural expectations, make the United States'' medical system an arena where the stresses of emigration are expressed and help is sought. We describe the influences of culture and aging on older emigrés'' health and interaction with the American medical system. A qualitative, exploratory study was done of problems and issues in health care use by older Russian emigrés at the ambulatory medical clinic of Mount Zion Medical Center, San Francisco. Cultural expectations and beliefs about health, adaptive health behaviors learned in the former Soviet Union, the stresses of emigration, and the medical realities of aging can result in serious problems in the care and treatment of older Russian emigrés. Recommended solutions include educating emigrés and health care professionals, integrating mental health services into the primary care setting, and expanding supportive services in the community such as adult day health care.
