Abstract
Although therapeutic opportunities in medicine continuously improve, death is inevitable in some cases due to limitations in treatment. When patients die without a conclusive diagnosis, autopsy studies can provide essential information in order to improve athophysiological reasoning. We describe two patients who died after a prolonged course of sepsis and were diagnosed with the unsuspected presence of aspergillosis at autopsy. Literature review demonstrates that due to apoptosis and immunological interactions, septic patients become susceptible to opportunistic infections, a state described as immunoparalysis.

Abstract
BACKGROUND The aim of this paper was to study long-term survival in patients treated in the Intensive Care Unit (ICU) and who survived to hospital discharge. METHODS This was a single-center retrospective cohort study of patients admitted to a mixed intensivist-led 10 bed ICU in a teaching hospital between 2004 and 2009 and discharged alive from the hospital with complete follow-up until January 1, 2011. RESULTS A total of 3477 individual patients were admitted to the ICU, 491 (14.1%) of whom died in the hospital while 2986 survived to hospital discharge. In the first year after discharge 436 out of 2986 (14.6%) patients died. Mortality after hospital discharge was highest in the first three months. For patients discharged alive from the hospital the risk of dying during the first year increased significantly with age, APACHE II score at admission and being discharged to a place other than home. Sepsis on ICU admission, mechanical ventilation, renal replacement therapy during ICU treatment or admission type had no effect on one-year mortality rate. CONCLUSION Patients who survive ICU treatment have a high risk of dying during the next year. This risk is almost as great the risk of dying during ICU and hospital treatment and increases with age and illness severity on admission to the ICU.

Abstract
Lifetime risk of developing endometrial cancer in Lynch syndrome carriers is very high and females are also at an increased risk of developing ovarian cancer. The aim of the study was to determine the impact of gynecological screening in MSH2 mutation carriers. Gynecological cancer incidence and overall survival was compared in female mutation carriers who received gynecological screening (cases) and in matched controls. Controls were randomly selected from non-screened mutation carriers who were alive and disease-free at the age the case entered the screening program. Median age to diagnosis of gynecological cancer was 54 years in the screened group compared to 56 years in controls (p = 0.50). Stage I or II cancer was diagnosed in 92% of screened patients compared to 71% in the control group (p = 0.17). Two of three deaths in the screened group were the result of ovarian cancer. Mean survival in the screened group was 79 years compared to 69 years in the control group (p = 0.11), likely associated with concomitant colonoscopy screening. Gynecological screening did not result in earlier gynecologic cancer detection and despite screening two young women died from ovarian cancer suggesting that prophylactic hysterectomy with bilateral salpingo-oophorectomy be considered in female mutation carriers who have completed childbearing.

Abstract
Nitrogen (N) deposition continues to threaten upland ecosystems, contributing to acidification, eutrophication and biodiversity loss. We present results from a monitoring study aimed at investigating the fate of this deposited N within a pristine catchment in the Cairngorm Mountains (Scotland). Six sites were established along an elevation gradient (486-908 m) spanning the key habitats of temperate maritime uplands. Bulk deposition chemistry, soil carbon content, soil solution chemistry, soil temperature and soil moisture content were monitored over a 5 year period. Results were used to assess spatial variability in soil solution N and to investigate the factors and processes driving this variability. Highest soil solution inorganic N concentrations were found in the alpine soils at the top of the hillslope. Soil carbon stock, soil solution dissolved organic carbon (DOC) and factors representing site hydrology were the best predictors of NO(3)(-) concentration, with highest concentrations at low productivity sites with low DOC and freely-draining soils. These factors act as proxies for changing net biological uptake and soil/water contact time, and therefore support the hypothesis that spatial variations in soil solution NO(3)(-) are controlled by habitat N retention capacity. Soil percent carbon was a better predictor of soil solution inorganic N concentration than mass of soil carbon. NH(4)(+) was less affected by soil hydrology than NO(3)(-) and showed the effects of net mineralization inputs, particularly at Racomitrium heath and peaty sites. Soil solution dissolved organic N concentration was strongly related to both DOC and temperature, with a stronger temperature effect at more productive sites. Due to the spatial heterogeneity in N leaching potential, a fine-scale approach to assessing surface water vulnerability to N leaching is recommended over the broad scale, critical loads approach currently in use, particularly for sensitive areas.

Abstract
BACKGROUND A national survey was undertaken to establish a baseline of our final year students' perception of how their undergraduate oral surgery education has equipped them for key areas of general dental practice. MATERIALS AND METHODS Questionnaires were distributed to the 13 UK schools with final year students, towards the end of the academic year in 2009. The questionnaires were completed anonymously and were optically scanned. RESULTS In total, 632 questionnaires were returned, which represents 66% of the students of the graduating year. The majority (83%) of the respondents perceived that the teaching in oral surgery had given them sufficient knowledge to undertake independent practise. Most respondents (99%) felt confident to perform forceps exodontia, but confidence in the various aspects of surgical exodontia was lower. A majority (83%) had experience of an outreach scheme performing forceps exodontia (75%) and surgical exodontia (16%) in this environment. Twenty per cent indicated a desire to undertake a career in oral surgery, 6% in oral and maxillofacial surgery and 35% in another speciality. CONCLUSION This survey suggests that the majority of the students perceive that the oral surgery education has prepared them well for key areas of general practice. It also suggests that there is, however, a need to provide further improvement in the delivery of surgical skills and knowledge.

Abstract
BACKGROUND The assessment of clinical skills is essential to determine whether an undergraduate is competent to perform the tasks outlined in the curriculum. Such assessments in dentistry have historically not been subjected to large scale validity and reliability testing due the relatively small student numbers at each institute. The aims of this study were to test the validity and reliability of a standardised, checklist-based, suturing objective structured clinical examination (OSCE) and then to perform a multicentre trial to determine its performance over a large cohort of students. MATERIALS AND METHODS A total of seven UK schools agreed to take part in the trial. To test the validity and reliability of the checklist, the examiner at each institution reviewed and scored video footage of 10 students performing the assessment. Each institution then carried out the assessment providing a checklist score and a global score for each of their own students. RESULTS The assessment was well received by the staff, with acceptable inter-examiner variability. In total, 496 students completed the suturing OSCE with a success rate of 81% with a variation between schools of between 66% and 96%. A significant correlation was found between the checklist score and the global score (r = 0.361, P = 0.000). No one item on the checklist was found to be a determinant factor in the outcome of the OSCE. CONCLUSIONS This checklist-based assessment of suturing skills was found to have face and content validity. Its reliability was promising, but merits further investigation. There may be an argument for the standardisation of the assessment of this core surgical skill throughout several UK-based dental schools.

Abstract
Administration of empiric antimicrobial therapy is standard practice in the management of neutropenic fever, but there remains considerable debate about the selection of an optimal regimen. In view of emerging evidence regarding efficacy and toxicity differences between empiric treatment regimens, and strong evidence of heterogeneity in clinical practice, the current guidelines were developed to provide Australian clinicians with comprehensive guidance for selecting an appropriate empiric strategy in the setting of neutropenic fever. Beta-lactam monotherapy is presented as the treatment of choice for all clinically stable patients while early treatment with combination antibiotic therapy is considered for patients at higher risk. Due consideration is given to the appropriate use of glycopeptides in this setting. Several clinical caveats, accounting for institution- and patient-specific risk factors, are provided to help guide the judicious use of the agents described. Detailed recommendations are also provided regarding time to first dose, timing of blood cultures, selection of a first-line antibiotic regimen, subsequent modification of antibiotic choice and cessation of therapy.

Abstract
UNLABELLED The assessment of competence in clinical skills has become more frequent in published healthcare curricula and syllabuses recently. There are agreed mechanisms for the assessment of competence in the post-graduate environment, but no consensus within the undergraduate curriculum. This paper seeks to develop an agreed generic checklist for the assessment of competence in forceps exodontia. MATERIALS AND METHODS A modified Delphi process was undertaken with representatives from all UK dental schools (n = 13) to develop a generic checklist for the assessment of competence in forceps exodontia. A content analysis of the assessments employed by each school was used to help discussion and inform the Delphi process. RESULTS Seven schools currently employ a summative assessment of competence in forceps exodontia, with the majority employing a structured clinical objective test (n = 6). From the seven assessments, there were a total of 29 putative items and 10 putative domains identified for a generic checklist. These were reduced to five domains and 19 items through the content analysis and Delphi process, and a generic overarching checklist was created. CONCLUSION Using this generic checklist, it may now be possible to pool data inter-institution to perform more powerful analyses on how our students obtain, or fail to obtain competence in forceps exodontia.
