During the past decade, medical therapy for AIDS has become more effective but also prohibitively expensive. A medical tragedy has been transformed into a financial crisis, and society has responded by establishing special programs and sources of funding for AIDS. These maneuvers parallel earlier approaches to HIV testing and reporting that have collectively come to be known as 'exceptionalism.

Forty-two patients diagnosed as having noncomplicated gallstones were studied prospectively. They were operated on by laparoscopy (LC, n = 21) or open surgery (OC, n = 21).

Community equipoise is an essential condition for physicians and patients to answer these questions: Should there be a trial? If so, what kind? We have argued that community equipoise exists because of changes in the knowledge gap between physicians and patients and in the moral justification of medical decision-making. Finally, we have briefly examined the social aspect of medical knowledge to argue that it necessarily includes patients and their values.

This study compared resource allocation to patients who eventually die in neonatal ICUs (NICUs) and adult medical ICUs (MICUs). It was performed via retrospective, chart review study at ICUs at the University of Chicago-an inner city, tertiary care, academic medical center. All patients were admitted to the neonatal, general medical, or coronary ICU during 1 calendar yr.

Design: Written survey of all MDs practicing NICU medicine in the US.
Participants: Two thousand four hundred ninety-eight NICU physicians as determined from three sources: a) the American Board of Medical Specialists; b) the American Academy of Pediatrics Section of Neonatal/Perinatal Medicine; and c) a listing of neonatologists provided by Ross Laboratories.
Polymorphonuclear leukocytes (PMN) are well recognised as being the principal cells in the inflammatory response reaction. The current investigation was designed to evaluate the stimulated state of neutrophils in patients undergoing open (OC) and laparoscopic cholecystectomy (LC). The superoxide radical generation of isolated PMN and its lag time, and PMN elastase were measured in peripheral venous blood samples collected from 42 patients.

In this study we aimed to investigate the mechanisms of injury regarding changes of neutrophil function. In our experiments the left descending coronary artery (LAD) was ligated in Beagle dogs for 1 hour followed by one hour reperfusion.

To gain information about the consequences of oxidative stress the investigation of plasma antioxidants seems to be plausible. In our study we used a new kit (RANDOX, England) for measurement of total antioxidant status (TAS) to determine whether it has diagnostic value in comparison with our earlier results of measuring other parameters of oxidative stress in the following diseases: i.

PMNs were isolated from healthy beagle dogs, and superoxide radical generation was induced by phorbol-myristate-acetate. Free radical generation capacity of stimulated PMNs were measured.

Our study focused on the acute phase response in order to clarify the better patient recovery following LC. Sixteen patients scheduled for elective cholecystectomy were equally allocated into groups of OC and LC.

The patients were randomised into two groups. Group one contained 21 patients treated by open cholecystectomy(OC).

We concluded that monitoring of this system we were able to detect not only the actual changes of lipid peroxidation and antioxidant defence mechanisms, but additionally the therapeutic efficacy of the treatment.

This study sought to characterize the attitudes that affect medical students' willingness to treat HIV-infected patients and to determine which attitudes are most amenable to intervention.
Method: All 414 matriculating medical students at three Chicago schools were surveyed in 1994.
It is standard practice for physicians to use blood gas (BG) evaluations when evaluating neonates with respiratory distress. In this study we addressed two questions: (1) What is the distribution of BG values in a population of infants receiving BG evaluation in the first 4 hours of life; and (2) How does the behavior of physicians correlate with BG values in these infants? We discuss the implications of our findings for claims about "standards" of medical care for newborn infants with respiratory distress. We reviewed medical records for 226 infants with birthweight > 2000 grams who were not intubated at the time of first BG determination.
View Article and Find Full Text PDFBabies of extremely low birthweight and elderly adults both require expensive and scarce resources, and both have a relatively poor prognosis for survival if they require intensive care. Thus, proposals for rationing often target one or both of these groups. We suspected that although mortality rates might be higher in the neonatal intensive care unit (NICU) than in the adult intensive care unit (ICU), NICU care might nevertheless be more cost effective, where cost efficiency is measured along the dimension of resources targeted to survivors.

A requirement of coherence, or principled consistency, is a hallmark of analogic reasoning (as it is of reasoning of almost all sorts)." In cases of alleged medical negligence, our current system of malpractice litigation supports the possibility that inaccurate anecdotal testimony by expert witnesses may be credited equally or even preferred to more accurate testimony based on empiric data.

As for many 25-year-old concepts, the obligatory centripetal design of many regionalization policies may need to be modified.

The left descending coronary artery (LAD) was occluded for 60 min in anaesthetized dogs followed by one hour of reperfusion. Blood samples were taken at different times of the occlusion and reperfusion for the determination of plasma concentration of malondialdehyde (MDA), reduced (GSH) and oxidized glutathione (GSSG); furthermore of the activity of catalase and superoxide dismutase (SOD).

We believe that much of this tension may be a result of the way the issue is framed. We began this study with the intuition that although many ELBW infants die, most succumb quickly.

The effect of lidocaine on brain lipid peroxidation, as reflected by jugular vein malondialdehyde concentrations, and of polymorphonuclear leukocyte activation in peripheral venous blood samples following transient global cerebral ischemia, were studied. In normothermic dogs subjected to a 10 min elevation of cerebrospinal fluid pressure and a subsequent 60 min reperfusion, the malondialdehyde concentration during the first 3 min of reperfusion increased significantly (p < 0.05) in the jugular vein.
