Upper and lower extremity injuries are common in children, with an overall risk of fracture estimated at just under 1 in 5 children. Pediatric bone anatomy and physiology produce age specific injury patterns and conditions that are unique to children, which can make accurate diagnosis difficult for emergency clinicians. This issue reviews the etiology and pathophysiology of child-specific fractures, as well as common injuries of the upper and lower extremities. Evidence-based recommendations for management of pediatric fractures, including appropriate diagnostic studies and treatment, are also discussed...

: Discovery of drugs for diseases of the central nervous system (CNS) faces high attrition rates in clinical trials. Neural diseases are extremely complex in nature and typically associated with multiple drug targets. A conception of multi-target directed ligands (MTDL), widely applied to discovery of cancer pharmaceuticals, may be a perspective solution for CNS diseases. Special bio-informatics approaches have been developed which can assist the medicinal chemists in identification and structural optimization of MTDL...

Many foreign medicinal materials that were imported to China via the Silk Road and maritime trade have enriched Chinese medicine. Imported foreign medicines reached a high point by the Tang and Song Dynasties, particularly in the case of aromatic medicines, which supplemented domestic Chinese aromatics and were widely employed in official dispensaries in the Song Dynasty. This study investigated historical records related to imported Chinese medicines in the Tang and Song periods, focusing on their varieties, quantity, use, and localization trends...

Post-marketing research in oncology has rarely been described. We aimed to characterize post-marketing trials for a consistent set of anticancer agents over a long period. We performed a cross-sectional analysis of post-marketing trials registered at ClinicalTrials.gov through September 2014 for novel anticancer agents approved by both the US Food and Drug Administration and the European Medicines Agency between 2005 and 2010. All relevant post-marketing trials were classified according to indication, primary outcome, starting date, sponsors, and planned enrollment...

Vascular anomalies constitute some of the most difficult diagnostic and therapeutic enigmas in the practice of medicine, ranging from an asymptomatic birthmark to life-threatening congestive heart failure. Hemangiolymphangiomas (HLA) are extremely rare vascular malformations of both lymphatic and blood vessels in which 80-90% are diagnosed during the first 2 years of life. Though rare, these vascular malformations have promising clinical outcomes. We report a case of a 28-year-old male who presented with a neck mass of unknown etiology...

BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs), e.g. sofosbuvir, are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may eradicate hepatitis C virus (HCV) from the blood (sustained virological response). Sustained virological response (SVR) is used by investigators and regulatory agencies as a surrogate outcome for morbidity and mortality, based solely on observational evidence...

Comprehensive characterization of the healthy human proteome baseline is essential for personalized medicine. Baseline data are necessary to understand the variation between individuals as well as longitudinal variation within individuals. Many important protein biomarkers, such as cytokines, exist at extremely low or undetectable levels in the healthy state. This paper describes results from a 14-week study of healthy human subjects using ultrasensitive single molecule array (Simoa) assays to measure both intra and intersubject variation of 15 cytokines...

REVIEW
Ioana Agache, Liliana Rogozea
Measurement of biomarkers has been incorporated within clinical research of asthma to characterize the population and to associate the disease with environmental and therapeutic effects. Regrettably, at present, there are no specific biomarkers, none is validated or qualified, and endotype-driven choices overlap. Biomarkers have not yet reached clinical practice and are not included in current asthma guidelines. Last but not least, the choice of the outcome upholding the value of the biomarkers is extremely difficult, since it has to reflect the mechanistic intervention while being relevant to both the disease and the particular person...

The invention of dialysis has been a phenomenal advance in the treatment of kidney failure. The introduction of artificial kidneys in clinical care remains one of the most successful lifesaving interventions in modern medicine. Its glory, however, has been tempered by poor long-term outcomes and a negative qualitative impact on the lives of patients who suffer from an extremely complex, burdensome, and restricted life on dialysis. There remains a huge gap in patient well-being and outcomes between artificial kidney treatments and kidney transplantation...

Policy Points: Introducing a recent special issue of The Lancet on the health system in France, Horton and Ceschia observe that "the dominance of English as the language of science and, increasingly, global health too often closes the door on the history and experiences of others."(1) In that spirit, this manuscript presents a detailed case study of public health policy transformation in France in the early 1990s. It casts light on processes of policy change in a political and cultural environment very different from that of the United States, showing how the public health policy process is shaped by multiple contingencies of history, ideology, and politics...

REVIEW
Matthew Dryden
The main solution to the global antibiotic resistance crisis is reducing the volume of antibiotic use in medicine, agriculture and the environment. However there is also a pressing need for novel antimicrobials. Despite much rhetoric, there are few entirely novel agents in development. One such therapy to reach clinical use is an agent using Reactive Oxygen Species (ROS), oxygen radicals, as an antimicrobial mechanism. ROS can be delivered to the site of infection in various formats. ROS is highly antimicrobial against Gram positive and negative bacteria, viruses and fungi...

REVIEW
Hsing-Ching Kuo, Kathleen M Friel, Andrew M Gordon
Children with unilateral spastic cerebral palsy (CP) often have mirror movements, i.e. involuntary imitations of unilateral voluntary movements of the contralateral upper extremity. The pathophysiology of mirror movements has been investigated in small and heterogeneous cohorts in the literature. Specific pathophysiology of mirror movements and their impact on upper extremity function require systematic investigation in larger and homogeneous cohorts of children with unilateral spastic CP. Here we review two possible neurophysiological mechanisms underlying mirror movements in children with CP and those with typical development: (1) an ipsilateral corticospinal tract projecting from the contralesional motor cortex (M1) to both upper extremities; (2) insufficient interhemispheric inhibition between the two M1s...

Cell metabolism is an extremely complicated dynamical system that maintains important cellular functions despite large changes in inputs. This "homeostasis" does not mean that the dynamical system is rigid and fixed. Typically, large changes in external variables cause large changes in some internal variables so that, through various regulatory mechanisms, certain other internal variables (concentrations or velocities) remain approximately constant over a finite range of inputs. Outside that range, the mechanisms cease to function and concentrations change rapidly with changes in inputs...

Myeloid malignancies are characterized by an extreme molecular heterogeneity, and many efforts have been made in the past decades to clarify the mechanisms underlying their pathogenesis. In this scenario SET binding protein 1 (SETBP1) has attracted a lot of interest as a new oncogene and potential marker, in addition to its involvement in the Schinzel-Giedon syndrome (SGS). Our review starts with the analysis of the structural characteristics of SETBP1, and extends to its corresponding physiological and pathological functions...

It has been more than 14 years since identification of the human genome. This phenomenon is creating a revolution in all components of the health-care world. To date, little has been included in the podiatric medical literature despite the fact that so many of the conditions affecting the pedal extremity have genomic implications. Genomics will have a major effect on prevention, diagnosis, and patient management and needs to be included in podiatric medical practice as well as in the curriculum of podiatric medical schools...
