#1
Alexandre Semionov, Karl Sayegh
Paragangliomas are rare neuroendocrine tumors arising from the ganglia of the sympathetic or parasympathetic nervous system. Less than 160 cases of intrapericardial or intracardiac paragangliomas have been reported in the English language peer-reviewed medical literature. Here, we report a case of intrapericardial paraganglioma, which illustrates some typical multimodality imaging features of this rare entity.

Network meta-analysis is a technique for comparing multiple treatments simultaneously in a single analysis by combining direct and indirect evidence within a network of randomized controlled trials. Network meta-analysis may assist assessing the comparative effectiveness of different treatments regularly used in clinical practice and, therefore, has become attractive among clinicians. However, if proper caution is not taken in conducting and interpreting network meta-analysis, inferences might be biased. The aim of this paper is to illustrate the process of network meta-analysis with the aid of a working example on first-line medical treatment for primary open-angle glaucoma...

Beamforming (BF) in ultrasound (US) imaging has significant impact on the quality of the final image, controlling its resolution and contrast. Despite its low spatial resolution and contrast, delay-and-sum (DAS) is still extensively used nowadays in clinical applications, due to its real-time capabilities. The most common alternatives are minimum variance (MV) method and its variants, which overcome the drawbacks of DAS, at the cost of higher computational complexity that limits its utilization in real-time applications...

Xiao Ye
A discussion on "Is traditional Chinese medicine (TCM) really relevant?" was held in the University College London (UCL) on the afternoon of 31st March, 2015. The author summarized some core viewpoints of the participants and then tried to focus on the opponent's opinions to clear up the arguments by illustrating respects of history, knowledge learning process, evidence based medicine (EBM) and strengths of TCM. This article will propose that the human health is extremely delicate and complicated and that no system of medicine can resolve all the problems of the human body...

Pulmonary hypertension (PH) is a complex condition that can occur as a result of a wide range of disorders, including left heart disease, lung disease and chronic pulmonary thromboembolism. Contemporary PH patients are older and frequently have a multitude of comorbidities that may contribute to or simply coincide with their PH. Identifying the cause of PH in these complicated patients can be challenging but is essential, given that the aetiology of the disease has a significant impact on the management options available...

BACKGROUND: The concept of shared-decision-making is a well-established approach to increase the participation of patients in medical decisions. Using lifetime risk or time-to-event (TTE) formats has been increasingly suggested as they might have advantages, e.g. in younger patients, to better show consequences of unhealthy behaviour. In this study, the most-popular ten-year risk illustration in the decision-aid-software arriba(TM) (emoticons), is compared within a randomised trial to a new-developed TTE illustration, which is based on a Markov model...

BACKGROUND: ST elevation myocardial infarction is a medical emergency and the electrocardiogram is a part of the mainstay in the initial diagnosis. A variety of non-cardiac conditions have been known to mimic the electrocardiographic changes seen in acute coronary syndrome. We present a patient presenting with acute partial intestinal obstruction causing gastric distension and intestinal dilatation who also had dynamic electrocardiographic changes, mimicking anterior ST elevation myocardial infarction...

Social scientists have proposed various theories as to when, why, and how people come to seek medical care for multiple conditions. Yet, there is still little empirical research to illustrate the pathways into and out of care, especially for chronic illness. This article contributes to this body of work by exploring individuals' reasons for delaying and seeking care for obstructive sleep apnea, which despite being the most diagnosed sleep disorder, has been largely neglected by social scientists. Drawing upon in-depth interviews with 65 Jewish-Israeli obstructive sleep apnea patients, this study shows how intersections of gender, family, and morality shape and are shaped by care-seeking behavior...

One of the most frequent chief complaints among older persons presenting in the emergency department (ED) is dizziness. Nurses in the ambulance and in the ED play an important role in managing these patients. The challenge in the ED or ambulance is to, with limited diagnostic equipment; decide the correct level of care. The aim of this study was to identify factors that differed between those who were admitted to hospital and those who were not among older persons (65+) presenting in the ED with dizziness. The method was a retrospective journal audit...

Status epilepticus requires treatment with emergent initial therapy with a benzodiazepine and urgent control therapy with an additional antiepileptic drug (AED) to terminate clinical and/or electrographic seizure activity. However, nearly one-third of patients will prove refractory to the aforementioned therapies and are prone to a higher degree of neuronal injury, resistance to pharmacotherapy, and death. Current guidelines for refractory status epilepticus (RSE) recommend initiating a continuous intravenous (CIV) anesthetic over bolus dosing with a different AED...

Nerissa Gailey
This article explores trans identities, as articulated within a few historical texts. From early literary depictions of gender difference, to medicalized conceptions of transsexualism, to a proliferation of trans and queer identities represented by an ever-expanding "alphabet soup" of identity labels, our understandings of identities, sexualities, and queer community-building continue to change. I utilize the notion of "kind-making," as elaborated upon in the work of Ian Hacking, to illustrate that some queer and trans identifications are affiliative, while others are contrastive or oppositional in nature, and these structural differences have important implications with respect to understanding identity and sexuality, and also trans inclusion within LGBT communities and activist efforts...

The design of phase I studies is often challenging, because of limited evidence to inform study protocols. Adaptive designs are now well established in cancer but much less so in other clinical areas. A phase I study to assess the safety, pharmacokinetic profile and antiretroviral efficacy of C34-PEG4 -Chol, a novel peptide fusion inhibitor for the treatment of HIV infection, has been set up with Medical Research Council funding. During the study workup, Bayesian adaptive designs based on the continual reassessment method were compared with a more standard rule-based design, with the aim of choosing a design that would maximise the scientific information gained from the study...

Bothrops erythromelas is a snake of medical importance responsible for most of the venomous incidents in Northeastern Brazil. However, this species is not included in the pool of venoms that are used in the Brazilian polyvalent bothropic antivenom (BAv) production. Furthermore, it is well known that antivenom therapy has limited efficacy against venom-induced local effects, making the search for complementary alternatives to treat snakebites an important task. Jatropha gossypiifolia is a medicinal plant widely indicated in folk medicine as an antidote for snakebites, whose effectiveness against Bothrops jararaca venom (BjV) has been previously demonstrated in mice...

REVIEW
Aasma Rafiq, M A Khanday
Extreme environmental and physiological conditions present challenges for thermal processes in body tissues including multi-layered human eye. A mathematical model has been formulated in this direction to study the thermal behavior of the human eye in relation with the change in blood perfusion, porosity, evaporation and environmental temperatures. In this study, a comprehensive thermal analysis has been performed on the multi-layered eye using Pennes' bio-heat equation with appropriate boundary and interface conditions...
