Teleradiology systems tackle the problem of transferring radiological images between medical image workstations for facilitating different medical activities, e.g., diagnosis, treatment and follow up a patient, medical training, or consulting second opinion. Nowadays, m-Health (aka mobile health) is becoming popular because of high quality of mobile displays, although remains a work in progress. In this paper a mobile teleradiology system is reported, which main contribution is the development of a platform: (1) supported by a Grid infrastructure, (2) using biomedical ontologies for adding semantic annotations on medical images, and (3) supporting semantic and content-based image retrieval...

BACKGROUND: Various metabolic diseases induced by eating disorders are some of the most serious and difficult problems for modern public healthcare. However, little is known about hyperphagia, partly because of the lack of a clear definition. Several basic studies have analyzed eating habits using endocrinological or neurophysiological approaches, which have suggested a controlled balance between the hunger and satiety centers in the central nervous system. However, more detailed neuro-radiologic evaluations have not been achieved for the hypothalamus, and evaluations were limited only to the floor of the third ventricles...

Urolithiasis is a common disease with increasing prevalence worldwide and a lifetimeestimated recurrence risk of over 50%. Imaging techniques play a critical role in the initial diagnosis, follow-up and urological management of urinary tract stone disease. The are many useful tools for diagnosing urolithiasis, including conventional plain radiography, intravenous urography, ultrasonography, computed tomography and magnetic resonance imaging. All these techniques have their own individual roles to play and also their limitations...

Hypertrophic pachymeningitis (HP) is an important neurologic complication of granulomatosis with polyangiitis (GPA, formerly Wegener's granulomatosis). The aim of this study is to investigate the clinical features, radiological findings, and diagnostic pitfalls of GPA-related HP. A retrospective chart review was performed to screen patients diagnosed with GPA at Samsung Medical Center between 1997 and 2016. Neurologic manifestation, laboratory findings, neuroimaging data, and clinical course were evaluated in all patients...

OBJECTIVE: United States Food and Drug Administration (FDA)-mandated postapproval studies have long been a mainstay of the continued evaluation of high-risk medical devices after initial marketing approval; however, these studies often present challenges related to patient/physician recruitment and retention. Retrospective single-center studies also do not fully represent the spectrum of real-world performance nor are they likely to have a sufficiently large enough sample size to detect important signals...

Background and study aims Data on clinical outcomes of endoscopic drainage of debris-free pseudocysts (PDF) versus pseudocysts containing solid debris (PSD) are very limited. The aims of this study were to compare treatment outcomes between patients with PDF vs. PSD undergoing endoscopic ultrasound (EUS)-guided drainage via transmural stents. Patients and methods Retrospective review of 142 consecutive patients with pseudocysts who underwent EUS-guided transmural drainage (TM) from 2008 to 2014 at 15 academic centers in the United States...

The etiology of fractures of the maxillofacial skeleton varies among studies, with motor vehicle accidents and assaults oftentimes the most common. The number of males outnumbers females throughout most studies. Fractures of the zygoma, orbit, and mandible are usually cited as most common fracture types. This study examines a single center's experience with regards to etiology and distribution of fractures. A retrospective review of all radiologically confirmed facial fractures in a level 1 trauma center in an urban environment was performed for the years 2000 to 2012...

BACKGROUND: While ultrasound (US), given its lack of ionizing radiation is currently the recommended initial imaging study of choice for the diagnosis of appendicitis in pediatric and young adult patients, it does have significant shortcomings. US is time intensive, operator dependent, and results in frequent inconclusive studies, thus necessitating further imaging, and admission for observation or repeat clinical visits. A rapid focused Magnetic Resonance Imaging (MRI) for appendicitis has been shown to have definitive sensitivity and specificity, similar to Computed tomography (CT) but without radiation and offers a potential alternative to US...

REVIEW
Nicolas Golse, René Adam
Liver metastases from breast cancer (LMBC) have long been considered as a systemic disease because of the hematological route of dissemination, requiring noncurative management. In fact, despite recent advances in drug therapies personalized to tumor phenotype, the chances of a cure are nil and there is little hope of long-term survivors after nonsurgical management alone. By contrast, there is a growing evidence in the literature for satisfactory long-term results after a combination of chemotherapy and liver resection, with 5-year survival reaching >40% in some series...

Importance: Robust collateral blood vessels have been associated with better neurologic outcome following acute ischemic stroke (AIS). The most commonly used methods for identifying collaterals are contrast-based angiographic imaging techniques, which are not possible in all patients after AIS. Objective: To assess the association between the presence of collateral vessels identified using arterial spin labeling (ASL) magnetic resonance imaging, a technique that does not require exogenous administration of contrast, and neurologic outcome in patients after AIS...

BACKGROUND: Displaced Colles' fractures are treated by manipulation and below elbow cast application. Malunion is a common complication, resulting in pain, mid-carpal instability, and post-traumatic arthritis. Fracture stabilization by percutaneous pinning is a simple, minimally invasive technique that helps prevent displacement of the fracture, thereby minimizing complications. This study aims to assess the amount of collapse after closed manipulation and percutaneous pinning with Kirschner wires (K-wires) and its correlation with the functional outcome of the wrist after union...

OBJECTIVE Most patients suffering from aneurysmal subarachnoid hemorrhage (aSAH) initially present to a hospital that lacks a neurosurgical unit. These patients require interhospital transfer (IHT) to tertiary facilities capable of multidisciplinary neurosurgical intervention. Yet, little is known about the effects of IHT on the outcomes of patients suffering from aSAH. In this study, the authors examined the effects of IHT and transport method on the timing of treatment, rebleed rates, and overall outcomes of patients who have experienced aSAH...

INTRODUCTION: Kienböck's disease is rare in patients with a neutral or positive ulnar variance. In these situations, treatment is challenging and controversial.Various intracarpal shortening osteotomy (ICSO) procedures have been proposed. OBJECTIVE: Study the effect of the type of ICSO (isolated capitate osteotomy or combined with hamate osteotomy) on the clinical and radiological outcomes in a retrospective series. METHODS: Patients with Kienböck's disease were treated with ICSO...

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant genetic disorder that is caused by mutations in mainly two genes, that is ENG, encoding endoglin (HHT1), or ACVRL1, encoding activin receptor-like kinase 1 (ALK-1/HHT2). HHT is characterized by recurrent epistaxis, mucocutaneous telangiectasia, and vascular visceral dysplasia responsible for visceral arteriovenous malformations (AVM). AIM: to report the experience of two university hospitals (Trousseau, Paris, and CHIC, Creteil) with screening children for HHT and pulmonary AVM (PAVM) using high resolution computed tomography (HRCT)...
