The role of physician variability in pain management is unknown. ⋯ Lower expectations for relief and less satisfaction in its management may contribute to the undertreatment of chronic pain. Perceptions of regulatory scrutiny may contribute to suboptimal pain management. These preliminary data highlight physician variability in pain decision making while providing insights into educational needs.

The purpose of this investigation was to study specifically those cases of sudden death out-of-hospital in the Reykjavik area that were due to non-cardiac causes the last 13 years, from January 1987 to December 31, 1999. ⋯ In this study the data were reported in accordance with the Utstein protocol and therefore drug intoxication and suicide are not grouped together. However, most if not all cases of drug intoxication appear to have occurred in an attempt of suicide. Except for cardiac disease drug intoxication and suicides were together the most common causes of sudden death out-of-hospital in those instances attended by the crew of the emergency ambulance. The results of resuscitation attempts are much worse when the cause for sudden death is non-cardiac. Survival was relatively best in cases of "suffocation" or "drowning".

The incidence of prostate cancer is related to aging. Its increase in the last 10 years, varies from country to country and according to ethnic group, with its greatest incidence among African-American males and the least among Asian males. Only two risk factors have thus far been clearly established for prostate cancer: familial aggregation and ethnic origin. ⋯ Using this transmission model and linkage analysis, three predisposing loci on chromosome 1: HPC-1 (hereditary prostate cancer 1: 1q24-25), PCaP (predisposing for prostate cancer: 1q42-43) and CAPB (predisposing for prostate and brain tumor: 1p36) and one locus on chromosome 20 (HPC20: 20q13) have been described. Moreover, X-linked transmission has been suggested and related to another predisposing gene locus: HPCX (Xq27-28). It is possible that a large proportion of familial prostate cancer is due not to segregation of a few major gene mutations transmitted according to a monogenic inheritance, but rather to familial sharing of alleles at many loci, each contributing to a small increase in cancer risk.

[Myocardial infarction and coronary artery ventricular fistulas due to blunt chest trauma]
An 18-year-old previously healthy, cigarette smoking man with no other risk factors for ischaemic heart disease, was admitted to hospital after being kicked in the chest by a horse. On arrival he complained about pain in the lower mediastinum. INVESTIGATIONS: The ECG showed sinus rhythm, right bundle branch block and convex bowed ST elevation in leads V1-V3. Sixty minutes after the incident the cardiac enzymes (creatinekinase-MB fraction, troponin I) were significantly raised. Despite an only slightly reduced left ventricular function documented by transthoracic echocardiography, SPECT-thallium scan showed large scintigraphic defects. Coronary heart disease was excluded by coronary angiography. Four small coronary-ventricular fistulas were identified. Laevocardiography showed a hypokinesia in the antero-septal region. DIAGNOSIS, TREATMENT AND COURSE: We assumed traumatic myocardial infarction of the anterior wall and rupture of multiple small coronary vessels, leading to coronary-ventricular fistulas. No interventional or surgical therapy was performed. Later on the left ventricular function became normal. Echocardiography merely outlined an akinetic scar in the middle of the septum. At exercise ECG test sixteen months later, the patient remained asymptomatic and was able to exercise without any signs of ischaemia up to a work load of 175 W. Furthermore, the fistulas could be seen by echocardiography. ⋯ Cardiac involvement should be considered in all cases of blunt chest trauma. In addition to a traumatic myocardial infarction fistulas may also, though rarely, occur. Myocardial scintigraphy after cardiac contusion is not suitable for diagnosing myocardial ischaemia or vitability.
