Abstract
A patient with fever, and haemorrhagic symptoms was admitted to a hospital in Glasgow on 2 October 2012. Since he had returned from Afghanistan, serum samples were sent for diagnosis at the Rare and Imported Pathogens Laboratory, where a real-time reverse transcriptase-PCR diagnosis of Crimean – Congo haemorrhagic fever was made within 3 hrs after receipt of the sample. Hereafter the patient was transferred to a high-security infectious diseases unit in London but died on 6 October.

Abstract
The TASC II working group reports on primary amputation incidence rates vary between 12 and 50 per 100,000 per year. The primary amputation rate does not only depend on co-morbidities like diabetes and PAD, but also on local factors like the regional availability of vascular surgeons and interventional radiologists and their case load. Further-more, several studies could show that increasing revascularisation rates have drastically reduced amputation rates in the US, with a 50% decrease in amputation rates during a 10 year study period and a corresponding increase in surgical and endovascular revascularisation rates. An analysis of national and state US databases confirmed a drop in major amputations and open surgical revascularisations, in favour of an increase in endovascular interventions. The same study observed an increase in minor amputations during the same period. However, it remains unclear whether this trend is a consequence of the increased usage of endovascular procedures in high-risk patients who are unfit for open surgery or of earlier endovascular intervention in less critical lesions. This review gives an overview of the incidence, indication, amputation-level finding and outcome of major amputations performed in critical limb ischemia (CLI) patients.

Abstract
Since the introduction of endovascular techniques for the treatment of aortic pathologies, clinical application of these lesser invasive procedures has increased exponentially during the last two decades and changed daily vascular practice completely. Starting in the infra-renal aorta, the indications for endovascular repair have gradually extended to the suprarenal aorta, aortic arch, descending and thoracoabdominal aorta. In addition, other pathologies than aneurysms have been treated by endovascular means, including dissection, traumatic injuries, penetrating aortic ulcer, intramural hematoma and aorto bronchial fistula. With increased application, short-term and longer-term technical failures have developed, in the majority of cases managed by repeat endovascular techniques. However, these complications cannot always be solved by endotechniques, requiring conversion to open surgery. At present there are additional reasons why open surgical repair remains a mainstay in the treatment of complex aortic diseases. Younger patients might choose for traditional surgery because of the unknown durability of complex endovascular reconstructions. Patients with connective tissue disease suffer from vulnerable aortic tissue in which endografts might behave different as compared to degenerative aneurysms. Therefore, the modern vascular surgeon should not only be trained in endovascular procedures but also master the wide spectrum of open surgical techniques. Besides anatomical knowledge and standard vascular handling, the surgeon must be familiar with unusual variations and unexpected situations.

Abstract
Sudden unexpected death in epilepsy (SUDEP) is a devastating complication of epilepsy and is not rare. The NIH and National Institute of Neurological Disorders and Stroke sponsored a 3-day multidisciplinary workshop to advance research into SUDEP and its prevention. Parallel sessions were held: one with a focus on the science of SUDEP, and the other with a focus on issues related to the education of health care practitioners and people with epilepsy. This report summarizes the discussions and recommendations of the workshop, including lessons learned from investigations of sudden infant death syndrome (SIDS), sudden cardiac death, autonomic and respiratory physiology, medical devices, genetics, and animal models. Recommendations include educating all people with epilepsy about SUDEP as part of their general education on the potential harm of seizures, except in extenuating circumstances. Increasing awareness of SUDEP may facilitate improved seizure control, possibly decreasing SUDEP incidence. There have been significant advances in our understanding of the clinical and physiologic features of SIDS, sudden cardiac death, and SUDEP in both people and animals. Research should continue to focus on the cardiac, autonomic, respiratory, and genetic factors that likely contribute to the risk of SUDEP. Multicenter collaborative research should be encouraged, especially investigations with direct implications for the prevention of SUDEP. An ongoing SUDEP Coalition has been established to facilitate this effort. With the expansion of clinical, genetic, and basic science research, there is reasonable hope of advancing our understanding of SUDEP and ultimately our ability to prevent it.

Abstract
This paper uses data from multiple surveillance systems to describe the experience in New Zealand with the second complete wave of pandemic influenza A(H1N1)2009 in 2010. Measures such as hospitalisation rates suggest the overall impact of influenza A(H1N1)2009 in 2010 was between half and two thirds that of the first wave in 2009. There was considerable regional and sub-regional variation with a tendency for higher activity in areas that experienced low rates in 2009. Demographic characteristics of the second wave were similar to those in 2009 with highest rates seen in children under the age of five years, and in indigenous Māori and Pacific peoples. Hospital services including intensive care units were not under as much pressure as in 2009. Immunisation appears to have contributed to the reduced impact of the pandemic in 2010, particularly for those aged 60 years and older.

Abstract
By means of an indirect immunofluorescence technique with the use of monoclonal antibodies, the location of the presumptive auxin transport carrier of pea stem tissue was identified in the plasma membranes at the basal ends of parenchyma cells sheathing the vascular bundles. The results represent what is believed to be the first direct evidence for the hypothesized basal efflux carrier conferring polarity to auxin transport in plant stems.

Abstract
In experiments carried out to investigate the acid secretion theory of auxin action, we utilized sodium orthovanadate, an agent found to be a selective inhibitor of a plasma membrane-associated H(+)-pumping ATPase in Neurospora [Bowman, B. J. & Slayman, C. W. (1979) J. Biol. Chem. 245, 2928-2934]. At 1 mM, vanadate inhibited auxin-enhanced medium acidification by pea epicotyl segments within 5 min, whether added 0.5 or 2.5 hr after auxin. Inhibition of acidification was total after 10-15 min but could be reversed within 10 min after vanadate removal. When given as a 40-min pretreatment, vanadate completely prevented any auxin-enhanced acidification. Vanadate inhibition of medium acidification by oat coleoptile segments was also total and reversible, but both inhibition and reversal occurred after longer lag times than in pea. Inhibitory effects of vanadate on elongation in pea and oat tissue closely paralleled its effects on acidification, and the inhibitory effect of vanadate on elongation could be reversed by an acidic buffer. Vanadate did not inhibit respiration or protein synthesis in pea epicotyl segments, although it strongly inhibited L-[(14)C]leucine uptake. These results indicate the importance of cell wall acidification for short- and long-term auxin-enhanced growth and suggest the participation in wall acidification of a plasma membrane-associated ATPase acting as an H(+) pump.

Abstract
The threshold of toxicological concern (TTC) concept proposes that an exposure threshold value can be derived for chemicals, below which no significant risk to human health or the environment is expected. This concept goes further than setting acceptable exposure levels for individual chemicals, because it attempts to set a de minimis value for chemicals, including those of unknown toxicity, by taking the chemical's structure or mode of action (MOA) into consideration. This study examines the use of the TTC concern concept for endocrine active substances (EAS) with an estrogenic MOA. A case study formed the basis for a workshop of regulatory, industry and academic scientists held to discuss the use of the TTC in aquatic environmental risk assessment. The feasibility and acceptability, general advantages and disadvantages, and the specific issues that need to be considered when applying the TTC concept for EAS in risk assessment were addressed. Issues surrounding the statistical approaches used to derive TTCs were also discussed. This study presents discussion points and consensus findings of the workshop.

Abstract
Liver biopsy is frequently required in HBeAg-negative disease to determine the stage of fibrosis. It can be difficult to distinguish cohorts with undetectable HBeAg who may have varying degrees of fibrosis due to different stages of disease. We have assessed the utility of transient elastography (TE) to evaluate differences in HBeAg-negative patients. A total of 220 HBsAg-positive individuals were studied: 125 (group 1) had an inactive HBsAg carrier state and 95 (group 2) were HBeAg-negative, anti-HBe-positive patients with persistently or intermittent elevation of alanine aminotransferase (ALT) and/or HBV DNA >10(5) copies/mL. Mean stiffness was 4.83 +/- 1.2 kPa in group 1 vs 8.53 +/- 6 kPa in group 2 (P < 0.001); statistically significant differences were also found between AST/ULN ALT/ULN ratios, HBV DNA in group 1 vs group 2, respectively (P < 0.001). In the multivariate analysis, the only variable independently associated with the stage of fibrosis was the stiffness. This study shows that mean hepatic stiffness by elastography is significantly lower in patients with inactive hepatitis B compared to those with HBeAg-negative disease. The procedure is a useful adjunct to diagnosis to confirm a clinical pattern of disease, and for more selective use of liver biopsy before considering antiviral therapy.
