Elizabeth A Cretara, Robert T Swan, Robert H Hill
A 50-year-old male presented with bilateral cicatricial entropion with subepithelial fibrosis and fornix foreshortening. Conjunctival biopsy showed lymphocytic infiltrate along the interface of the epithelium and lamina propria with linear, shaggy fibrinogen deposition along the epithelial basement membrane zone, supporting a diagnosis of lichen planus. The patient was treated with commercially available topical cyclosporine for 5 months after which bilateral lower eyelid splitting procedure with recession of the anterior lamella and complete excision of the lower eyelid lashes was performed...

REVIEW
George J F Swan, Steve M Redpath, Stuart Bearhop, Robbie A McDonald
As a result of ecological and social drivers, the management of problems caused by wildlife is becoming more selective, often targeting specific animals. Narrowing the sights of management relies upon the ecology of certain 'problem individuals' and their disproportionate contribution to impacts upon human interests. We assess the ecological evidence for problem individuals and confirm that some individuals or classes can be both disproportionately responsible and more likely to reoffend. The benefits of management can sometimes be short-lived, and selective management can affect tolerance of wildlife for better or worse, but, when effectively targeted, selective management can bring benefits by mitigating impact and conflict, often in a more socially acceptable way...

Dimethylsulfoniopropionate (DMSP) and eleven other target zwitterions were quantified in the branch tips of six Acropora species and Stylophora pistillata hard coral growing on the reef flat surrounding Heron Island in the southern Great Barrier Reef (GBR), Australia. Hydrophilic interaction liquid chromatography mass spectrometry (HILIC-MS) was used for sample analysis with isotope dilution MS applied to quantify DMSP. The concentration of DMSP was ten times greater in A. aspera than A. valida, with this difference being maintained throughout the spring, summer and winter seasons...

Nicotinamide adenine dinucleotide is a coenzyme present in all kingdoms of life and exists in two forms: oxidized (NAD(+)) and reduced (NADH). NAD(H) is involved in a multitude of essential metabolic redox reactions, providing oxidizing or reducing equivalents. The ratio of free intracellular NAD(+)/NADH is fundamentally important in the maintenance of cellular redox homeostasis (Ying, 2008). Various chromogenic cycling assays have been used to determine the ratio of NAD(+)/NADH in both bacterial and mammalian cells for more than forty years (Bernofsky and Swan, 1973; Nisselbaum and Green, 1969)...

The condition of proximal interphalangeal joint (PIPJ) locking in hyperextension may occur in the athetoid or spastic hand with moderate or severe swan-neck deformity at the 'opening' phase of prehension. The patient's complaints are of complete or incomplete locking that may require passive assistance to initiate PIPJ flexion. Surgical procedures to overcome this include rerouting the lateral band, stabilisation or reconstruction procedure for the volar instability of the PIPJ, etc. Volar stabilisation may be achieved by Flexor digitorum superficialis (FDS) tenodesis procedures or criss-cross tendon graft for volar plate reconstruction...

EDITORIAL
Damian Roland
"Black Swans", originally described as an economic theory, are unexpected events whose potential to occur only becomes apparent after they have happened. The concept is very relevant to the practice of Emergency Medicine and this article explores how black swans impact on emergency care and how staff unconsciously aim to mitigate against them.

Viruses are major pathogens in all biological systems. Virus propagation and downstream analysis remains a challenge, particularly in the ocean where the majority of their microbial hosts remain recalcitrant to current culturing techniques. We used a cultivation-independent approach to isolate and sequence individual viruses. The protocol uses high-speed fluorescence-activated virus sorting flow cytometry, multiple displacement amplification (MDA), and downstream genomic sequencing. We focused on 'giant viruses' that are readily distinguishable by flow cytometry...

Gliomas are primary brain tumours arising from the glial cells of the nervous system. The diffuse nature of spread, coupled with proximity to critical brain structures, makes treatment a challenge. Pathological analysis confirms that the extent of glioma spread exceeds the extent of the grossly visible mass, seen on conventional magnetic resonance imaging (MRI) scans. Gliomas show faster spread along white matter tracts than in grey matter, leading to irregular patterns of spread. We propose a mathematical model based on Diffusion Tensor Imaging, a new MRI imaging technique that offers a methodology to delineate the major white matter tracts in the brain...

Acute massive pulmonary embolism (PE) is associated with high fatality, and catheter-directed thrombolytic therapy has been shown to be an efficacious treatment for this condition. We herein report a patient who developed acute massive PE but could not undergo the conventional catheter-directed thrombolytic therapy. A Swan-Ganz pulmonary artery catheter was placed at bedside to initiate immediate thrombolytic infusion, which resulted in dramatic clinical improvement. This report underscores a potential role of thrombolytic therapy via a trans-jugular pulmonary artery catheter in patients with acute massive PE who could not undergo the conventional catheter-based thrombolytic intervention...

BACKGROUND: The comparison of traits in twins from opposite-sex (OS) and same-sex (SS) dizygotic twin pairs is considered a proxy measure of prenatal hormone exposure. To examine possible prenatal hormonal influences on anthropometric traits, we compared mean height, body mass index (BMI), and the prevalence of being overweight or obese between men and women from OS and SS dizygotic twin pairs. METHODS: The data were derived from the COllaborative project of Development of Anthropometrical measures in Twins (CODATwins) database, and included 68,494 SS and 53,808 OS dizygotic twin individuals above the age of 20 years from 31 twin cohorts representing 19 countries...

BACKGROUND: Sentinel headache (SH) is estimated to occur prior to rupture of an aneurysm in 15-60% of aneurysmal subarachnoid hemorrhage (aSAH) cases. Non-contrasted computed tomography (CT) of brain and lumbar puncture are both negative, by definition, in patients presenting with SH. One of the theories explaining this phenomenon is micro-hemorrhage (MH) from the aneurysm wall contributing to iron deposition in the interface between the aneurysm wall and brain parenchyma. Quantitative susceptibility mapping (QSM) is a recently introduced magnetic resonance imaging (MRI) technique that has been shown capable of localizing the deposition of paramagnetic metals, particularly ferric iron...

A 17-month-old neutered male domestic shorthair cat was referred for a computed tomographic (CT) study of the thorax due to respiratory distress. Multidetector CT angiography showed a multifocal interstitial ground glass opacity, tortuous and blunted pulmonary arteries consistent with thromboembolism with perivascular lung infiltration and hypoventilation in multiple lung lobes. A blood antigen test was positive for Dirofilaria immitis. The cat's clinical condition rapidly declined and the owners elected euthanasia...

BACKGROUND: Prognosis for women with abdominal aortic aneurysm might be worse than the prognosis for men. We aimed to systematically quantify the differences in outcomes between men and women being assessed for repair of intact abdominal aortic aneurysm using data from study periods after the year 2000. METHODS: In these systematic reviews and meta-analysis, we identified studies (randomised, cohort, or cross-sectional) by searching MEDLINE, Embase, CENTRAL, and grey literature published between Jan 1, 2005, and Sept 2, 2016, for two systematic reviews and Jan 1, 2009, and Sept 2, 2016, for one systematic review...

More women with heart disease are reaching reproductive age and will want to embark upon pregnancy. Furthermore, many of these women are delaying pregnancy until later in life when they may be exposed to a greater number of complications from their heart disease. A relatively high proportion of these women will pursue fertility treatment to achieve a pregnancy; consequently, the management of subfertile couples where the woman (or man) has heart disease is of growing importance. In this review, we discuss how fertility investigations and treatment can impact a women with heart disease and how some of the potential complications can be minimized or avoided...
