Context: To clarify the social issues and problems associated with burn care in Japan, based on a cost analysis of acute burn care.', 'A retrospective review was undertaken of 71 patients admitted with burns at Nippon Medical School between January 1 and December 31, 1997. A cost analysis was performed for three major burn patients with a burn surface area (BSA) of 70% to 80% and three minor burn patients with a BSA of 20% to 30%. A questionnaire was administered to both burn patients and medical providers in all 127 emergency centers to help improve long-term quality of life (QOL).', '80% of burn patients were under age 70. In the major burn cases, the amount of reimbursement according to the government-regulated fee schedule was much less than the cost of treatment. The ratio of the cost of both medication and materials to total cost of treatment was higher for patients with major burns. Patients responding to the survey acknowledged being generally happy despite suffering from psychological and financial problems. A total of 413 medical providers from 63 institutions responded to the survey regarding improving long-term QOL.
Answer: Acute burn care is a costly service. The goal of burn care should shift from saving lives to allowing for a productive return to society. Quality improvement, outcome measurement, and technology assessment combined with health economics research for burn care should be carried out in Japan.

Ex Output:
Do the cost of burn care and implications for efficient care?

Context: Observational and clinical studies suggest different responses upon sex hormone replacement therapy in ischaemic heart disease. Few studies, however, have examined the impact of oestrogen receptor-dependent mechanisms on the extent of injury after myocardial infarction (MI). Therefore, we set out to evaluate the effect of oestrogen (E2) replacement on infarct size and remodelling, and the respective role of the oestrogen receptors (ER)alpha and -beta in this process, using ERalpha- and ERbeta-deficient mice.', 'Wild type (WT) (ERalpha(+/+) and ERbeta(+/+)), ERalpha-deficient (ERalpha(-/-)) and ERbeta-deficient (ERbeta(-/-)) mice were ovariectomized and subsequently supplemented with E2 or placebo using subcutaneous 60-day release pellets. MI was induced by left coronary artery ligation. Two weeks following MI, haemodynamic function was assessed and infarct size was determined.', 'There was no significant difference in infarct size between E2- or placebo-treated WT (ERalpha(+/+) and ERbeta(+/+)) mice. Surprisingly, E2 treatment did result in smaller infarct sizes in ERalpha(-/-) mice, but increased the infarct size in ERbeta(-/-) mice. Increase of the left ventricular mass post-MI was significantly larger in the E2-treated ERalpha(-/-) animals compared with placebo-treated animals. E2 treatment also significantly increased post-MI mortality in ERalpha(+/+), ERbeta(+/+) and ERalpha(-/-) animals, but not in ERbeta(-/-) mice.
Answer: Although E2 modulates the infarct size in ERalpha(-/-), it also appears to be responsible for the higher mortality following MI. ERbeta appears to be the receptor involved in the modulating effects of E2 in the infarcted heart.

Does oestrogen modulate cardiac ischaemic remodelling through oestrogen receptor-specific mechanisms?

Context: Stressors negatively impact emotional state and drive drug seeking, in part, by modulating the activity of the mesolimbic dopamine system. Unfortunately, the rapid regulation of dopamine signaling by the aversive stimuli that cause drug seeking is not well characterized. In a series of experiments, we scrutinized the subsecond regulation of dopamine signaling by the aversive stimulus, quinine, and tested its ability to cause cocaine seeking. Additionally, we examined the midbrain regulation of both dopamine signaling and cocaine seeking by the stress-sensitive peptide, corticotropin releasing factor (CRF).', 'Combining fast-scan cyclic voltammetry with behavioral pharmacology, we examined the effect of intraoral quinine administration on nucleus accumbens dopamine signaling and hedonic expression in 21 male Sprague-Dawley rats. We tested the role of CRF in modulating aversion-induced changes in dopamine concentration and cocaine seeking by bilaterally infusing the CRF antagonist, CP-376395, into the ventral tegmental area (VTA).', 'We found that quinine rapidly reduced dopamine signaling on two distinct time scales. We determined that CRF acted in the VTA to mediate this reduction on only one of these time scales. Further, we found that the reduction of dopamine tone and quinine-induced cocaine seeking were eliminated by blocking the actions of CRF in the VTA during the experience of the aversive stimulus.
Answer: These data demonstrate that stress-induced drug seeking can occur in a terminal environment of low dopamine tone that is dependent on a CRF-induced decrease in midbrain dopamine activity.

Do aversive stimuli drive drug seeking in a state of low dopamine tone?
