p6 the United States, medical geography is one of the least known of the medically related social sciences. Medical geography is concerned with the analysis of spatial patterns of disease and medical care provision.
Spatial analyses of disease patterns have been used by investigators as one tool with which to address problems of disease causation. However, while the results of spatial studies may be suggestive, they have been definitive only rarely. This is because there are numerous epistemological, logical and methodological problems which are encountered in spatial analysis. It is important to address these problems as one step in answering the basic issues concerning the role of spatial analysis in the detection of disease causation.
Regional health systems planning implicitly incorporates information about the distance behavior of hospital patients, in specifying hospital catchment areas, service-specific catchment areas and levels of centralization. Distance behavior of patients varies depending on their diagnoses and on the treatment and diagnostic procedure(s). In this study, a variety of procedures, ranging from those which are routine to those which are highly specialized, are analyzed within the framework of distance behavior. Regionalization of selected services will, by definition, affect distance behavior.
Horseradish peroxidase gel implants into either the nucleus raphe magnus (NRM) or inferior olive (IO) led to large numbers of retrogradely labeled cells in the prerubral subthalamic region in a cell group that surrounds the fasciculus retroflexus, which we suggest should be referred to as the nucleus parafascicularis prerubralis (nPfPr) to avoid the confusion of previous terminology. Autoradiographic studies, following injections of tritiated leucine into the nPfPr, confirmed projections to both medullary raphe nuclei (MRN) and IO. This common prerubral projection to IO, a well-established precerebellar nucleus, and MRN, again raises the question of whether the latter are involved in brainstem-mediated reflexes in addition to their well documented role in analgesic mechanisms.

Emergency Medical Service (EMS) evaluation is usually conducted on an aggregated, system-wide basis, despite the fact that there is substantial geographical variation in EMS performance. This paper suggests a method for the identification and analysis of geographically disaggregated EMS performance, using Seattle's Medic I program as an example.

A major concern in emergency medical services (EMS) planning has been the need to minimize ambulance response time, only one of several delays in reaching definitive care. Other important delays include patient delay in seeking medical care and dispatch delay. In this study, the importance of response time in light of other delays is discussed, and response time as one determinant of patient survival is analyzed, using Seattle's EMS system as a case study. The major conclusion is that paramedic response times influence short-term patient survival.
Research themes of interest to both clinical and social sciences have been proliferating in recent years. While the personal experiences of individuals who conduct interdisciplinary research probably vary widely, several general models of research and its conduct seem to be quite common. This is illustrated using the author's personal experiences, beginning from his disciplinary roots in medical geography.
