Strained achilles tendon complicated by nocturnal dyspepsia probably caused by ibuprofen: a case report
A 56-year-old male who is overweight experienced pain in his Achilles tendon after running four miles. He subsequently developed a severe limp. The condition was complicated by nocturnal dyspepsia probably caused by ibuprofen. His pain and limp were gone in six days.

Estimating the economic impact of pandemic influenza: An application of the computable general equilibrium model to the UK

 Abstract
 
 There is concern regarding the impact that a global infectious disease pandemic might have, especially the economic impact in the current financial climate. However, preparedness planning concentrates more upon population health and maintaining a functioning health sector than on the wider economic impact. We developed a single country Computable General Equilibrium model to estimate the economic impact of pandemic influenza (PI) and associated policies. While the context for this development was the United Kingdom, there are lessons to be drawn for application of this methodology, as well as indicative results, to other contexts.
 Disease scenarios were constructed from an epidemiological model which estimated case fatality rates (mild, moderate and severe) as 0.06%, 0.18% and 0.35%. A clinical attack rate of 35% was also used to produce influenza scenarios, together with preparedness policies, including antivirals and school closure, and the possible prophylactic absence of workers.
 UK cost estimates (in Sterling) are presented, together with relative percentage impacts applicable to similar large economies. Percentage/cost estimates suggest PI would reduce GDP by 0.3% (£3.5bn), 0.4% (£5bn) and 0.6% (£7.4bn) respectively for the three disease scenarios. However, the impact of PI itself is smaller than disease mitigation policies: combining school closure with prophylactic absenteeism yields percentage/cost effects of 1.1% (£14.7bn), 1.3% (£16.3bn) and 1.4% (£18.5bn) respectively for the three scenarios. Sensitivity analysis shows little variability with changes in disease parameters but notable changes with variations in school closure and prophylactic absenteeism. The most severe sensitivity scenario results in a 2.9% (£37.4bn), 3.2% (£41.4bn) and 3.7% (£47.5bn) loss to GDP respectively for the three scenarios.

Assessing the macroeconomic impact of a healthcare problem: the application of computable general equilibrium analysis to antimicrobial resistance.
There is a positive relationship between the health of a nation and its economic prosperity. However, in evaluating health care, economists typically concentrate on the economic impact only to the health (care) sector, which may mis-specify the social costs and benefits of a disease or intervention. This paper demonstrates the value of using a macroeconomic approach to modelling a major health problem, using the context of antimicrobial resistance and the application of the computable general equilibrium technique. This approach is described in detail and its 'added value' demonstrated in the case of AMR.

Use, option and externality values: are contingent valuation studies in health care mis-specified?
A general population sample of Australian respondents completed a contingent valuation (CV) survey that asked them to value six scenarios. These varied according to whether the scenario was seeking to elicit: (i) use value; (ii) externality value; (iii) option value; or (iv) a combination. Results indicate that use plus externality and/or option value was significantly greater than use value alone. As CV studies in health (care) overwhelmingly focus on use value alone - often implicitly through study design rather than explicitly - this raises the possibility of mis-specification in CV research in health (care). The implications for CV in health (care) are considered.

Contingent valuation in health care: does it matter how the 'good' is described?
A general population sample of 104 Australian respondents completed an interviewer-administered contingent valuation (CV) survey that asked them to value five scenarios representing the same core improvement in health status. These scenarios varied only in the degree of narrative used to describe the condition causing the health problem being valued and labeling of this health problem. Results indicate no significant difference in willingness to pay (WTP) between expressing symptoms as a brief or moderate narrative, but a significantly lower WTP value when expressed in an extensive narrative. WTP also differed significantly according to condition 'labels'. Possible implications for CV research are outlined.

Mood changes, obstetric experience and alterations in plasma cortisol, beta-endorphin and corticotrophin releasing hormone during pregnancy and the puerperium.
The relationships between mood change, obstetric experience and alterations in plasma cortisol, beta-endorphin (beta-EP) and corticotrophin-releasing hormone (CRH) were examined in a prospective study of 97 primiparous Australian women. Psychological measures were administered between the 28th week of pregnancy and the 3rd postnatal month, including the Profile of Mood States (POMS) and the Montgomery Asberg Depressive Rating Scale (MADRS). Blood samples were collected for cortisol, beta-EP and CRH assay on most of these occasions and during labour. Factor analysis was used to identify key subsets of psychological variables for use in the subsequent analyses. 'Mood disturbance' and 'tiredness' factors peaked at 38 weeks' gestation, while 'difficulty falling asleep' was greatest around the time of birth. Cortisol, beta-EP and CRH concentrations rose significantly as pregnancy advanced and peaked at birth; plasma CRH correlated with plasma cortisol (r = 0.54) and beta-EP (r = 0.32). Women with the highest 'mood disturbance' and MADRS depression scores at 28 weeks' gestation received significantly more pain relief during labour. Those women whose mood deteriorated from 38 weeks' gestation to postnatal day 2 had larger falls in plasma beta-EP after delivery (p less than 0.01) than those women whose mood improved or remained constant. Women in this mood-deteriorated subgroup also had significantly higher MADRS depression scores at 3 months (p less than 0.01). Mild antenatal depression (MADRS greater than 13) occurred in 5.2% of women and mild postnatal depression in 4.7%. Overall, these data suggest a role for circulating CRH in the regulation of maternal cortisol secretion and significant relationships between maternal postnatal mood states and beta-EP and between antenatal mood states and obstetric events.
