Paradoxical embolism is a known complication with intra-cardiac shunts. It should be considered in the differential as the pathophysiologic mechanism of simultaneous thromboembolism in the venous and systemic vasculature. We present a case of simultaneous deep venous thrombosis, pulmonary embolism and myocardial infarction in the presence of a confirmed patent foramen ovale on echocardiography. Thrombolytic therapy was administered. Subsequent concerns of intracranial hemorrhage on imaging of the brain complicated the management and added to the challenge of co-managing the clot burden in our patient...

CONTEXT: Recent public outcry has highlighted the rising cost of prescription drugs worldwide, which in several disease areas outpaces other health care expenditures and results in a suboptimal global availability of essential medicines. METHOD: A systematic review of Pubmed, the Financial Times, the New York Times, the Wall Street Journal and the Guardian was performed to identify articles related to the pricing of medicines. FINDINGS: Changes in drug life cycles have dramatically affected patent medicine markets, which have long been considered a self-evident and self-sustainable source of income for highly profitable drug companies...

Valerie A R Juniat, Saul Rajak
The treatment of midfacial tumours with radiotherapy, chemotherapy and radio-iodine can cause nasolacrimal duct fibrosis resulting in epiphora. Nasolacrimal patency can be maintained by stenting. We report our experience of prophylatic Nunchaku stent insertion in 5 patients prior to midfacial radiotherapy. Four out of 5 patients (80%) had patent nasolacrimal ducts without any symptoms of epiphora following removal of the stents. One patient was initially asymptomatic with patent nasolacrimal duct, but subsequently developed epiphora...

Microsurgery is a technically demanding field with long learning curves. Robotic-assisted microsurgery has the ability to decrease these learning curves. We, therefore, sought to assess the feasibility of robotic-assisted microvascular surgery in a rat model, and whether this could be translated into a worthwhile skills acquisition exercise for residents. Twenty-eight rats underwent microvascular anastomosis. Procedures were performed by a trained microvascular surgeon with no robotic experience (n = 14), or a trained robotic surgeon with no microvascular experience (n = 14)...

Concerns have been voiced about the ethical implications of patenting practices in the field of biotechnology. Some of these have also been incorporated into regulation, such as the European Commission Directive 98/44 on the legal protection of biotechnological inventions. However, the incorporation of ethically based restrictions into patent legislation has not had the effect of satisfying all concerns. In this article, we will systematically compare the richness of ethical concerns surrounding biotech patenting, with the limited scope of ethical concerns actually addressed in the patent system...

Novel synthetic opioids (NSO) are increasingly encountered in illicit heroin and counterfeit pain pills. Many NSO are resurrected from older biomedical literature or patent applications, so limited information is available about their biological effects. Here we examined the pharmacology of three structurally-distinct NSO found in the recreational drug market: N-(1-(2-phenylethyl)-4-piperidinyl)-N-phenylbutyramide (butyrylfentanyl), 3,4-dichloro-N-[(1R,2R)-2-(dimethylamino)cyclohexyl]-N-methylbenzamide (U-47700) and 1-cyclohexyl-4-(1,2-diphenylethyl)piperazine (MT-45)...

Babesia canis is the predominant Babesia species in dogs in Europe and is responsible for a severe and fatal disease. An increase in global pet tourism and a widening of the geographic distribution of the tick vector has led to the emergence of infections in areas where previously only imported cases have been reported. Due to the potential for rapid and serious disease progression, direct parasite detection by stained blood smears and light microscopy or DNA-based methods have traditionally been used for the diagnosis of acute infections...

The high prices of specialty pharmaceuticals are causing some public programs to ration care and many private insurers, including Medicare drug plans, to place specialty drugs on high cost sharing tiers. As a result, access to these drugs is severely restricted, and only a small portion of the population with the disease is receiving treatment. This concern has generated a wide range of proposed solutions. We conducted a literature review and identified fifty-two solutions in the peer reviewed literature that we classified into five broad categories: revising the patent system; encouraging research to increase development of new drugs; altering pharmaceutical regulation; decreasing market demand; and developing innovative pricing strategies...

Colorectal cancer (CRC) is a leading cause of tumor-related morbidity and mortality worldwide, with mortality most often attributable to metastatic disease. Bevacizumab, a humanized monoclonal antibody targeting vascular endothelial growth factor, has a significant role in the treatment of metastatic CRC (mCRC). However, patient access to bevacizumab may be limited in some regions or circumstances, owing to factors related to insurance coverage, reimbursement, patient out-of-pocket costs, or availability. As a result, outcomes for patients with mCRC may be worsened...

Left-sided coronary revascularization with bilateral internal thoracic artery (BITA) graft is performed usually either with an in situ (double source) or Y-graft configuration (single source). Two hundred fifty-three (mean age, 67.1 ± 9.5 years) patients underwent isolated left-sided coronary revascularization with BITA graft alone at the present authors' institution (2000-2015). Skeletonized BITA grafts were used either in an in situ (n = 199) or Y-graft configuration (n = 54). Forty pairs were identified with the propensity score-matching...

The aim of choanal atresia (CA) surgery is to achieve bilateral nasal patency. Among the different methods of CA repair, the endoscopic transnasal approach has gained recent popularity with the advent of endoscopic instruments and techniques. This article describes our experience regarding CA repair that was done either using or not using a stent in different periods of time in our department. Between February 2006 and February 2016, a total of 29 patients aged 2 days-53 years underwent endoscopic transnasal CA repair...

Caffeine is the most frequently used medication in the neonatal intensive care unit. It is used for the prevention and treatment of apnea, although this has been associated with lower incidence of bronchopulmonary dysplasia (BPD) and patent ductus arteriosus as well as intact survival at 18-21 months of life. Although neurodevelopmental advantage was no longer statistically significant at age 5 years, caffeine was associated with sustained improvement in co-ordination and less gross motor impairment than placebo...

Phosphodiesterases are proving to be fruitful targets for drug discovery. At the same time fragment-based drug discovery has matured into a powerful and widely applied technique. In this communication we review the application of fragment-based drug discovery for the successful identification of novel 3',5'-cyclic nucleotide phosphodiesterase (PDE) inhibitors, concentrating on both experimental and computational strategies for fragment screening and hit-to-lead development. To this end, we also mine the open access databases ChEMBL and PDB for fragments showing PDE inhibitory activity, as well as SureChEMBL for recent PDE related patents, to provide a wider context for exploring fragment diversity...
