This case describes a complication of bone cement use. A 65-year-old male patient with back spine trauma caused by a fall, underwent a percutaneous vertebroplasty. Five years later, he consulted for palpitations, and the electrocardiogram showed supraventricular arrhythmia. A transthoracic two-dimensional echocardiography showed a hyperechogenic linear structure of 7 cm length, running from the lateral wall of the right ventricle to the right atrium through the tricuspid valve. This foreign body, which was suspicious for bone cement embolism, appeared rigid and was attached at the lateral wall of the right ventricle, with its proximal end free in the right atrium...

INTRODUCTION: Isolated capitellar fracture is a rare injury accounting for 1% of all elbow fractures Bryan and Morrey (1985) and Poynton et al. (1998). In children, a fall on an outstretched hand, before the fusion of the epiphysis, usually leads to lateral condyle physeal fractures. Very few cases of capitellar fractures in the paediatric population have been reported. PRESENTATION OF CASE: Our patient, a 9-year-old girl presented with a capitellar fracture and lateral collateral ligament (LCL) avulsion of her left elbow...

REVIEW
P Richard
The diaphragm is the muscle most implicated in breathing. Its morphological exploration usually depends on pulmonary radiography, fluoroscopy, CT-scanning and MRI. Its function is evaluated by the classical respiratory functional tests, the measurement of maximum inspiratory and expiratory pressures, the transdiaphragmatic pressure and even an electromyogram. Ultrasound is a technique still insufficiently used in respiratory medicine. It offers, however, many advantages: it is easy to implement, there is no irradiation, it is usable at the bedside, particularly when the patient is immobile or in intensive care...

This case report describes the diagnosis of a traumatic periapical lesion, caused by parafunctional habits (bruxism) and associated with bone rarefaction, that had not been identified by periapical radiography. Slight edema was observed clinically at the apical region of the maxillary left canine; however, the tooth demonstrated only physiologic mobility, and the results of a pulpal sensitivity test were inconclusive. A cone beam computed tomogram (CBCT) showed the presence of a periapical lesion. After preparation of the root canal, intracanal medication (calcium hydroxide and paramonochlorophenol) was placed and changed once a month for 2 months...

BACKGROUND: Demographic changes are leading to an ageing population in Europe, and predict an increase in the number of nursing home residents over the next 30 years. Nursing home residents need specialised healthcare services such as radiology due to both chronic and acute illnesses. Mobile radiography, x-ray examinations performed in the nursing homes, may be a good way of providing services to this population. The aim of this systematic review was to identify the outcomes of mobile radiography services for nursing home residents and society...

Guang Li, Travis C Greene, Thomas K Nishino, Charles E Willis
The purpose of this study was to evaluate several of the standardized image quality metrics proposed by the American Association of Physics in Medicine (AAPM) Task Group 150. The task group suggested region-of-interest (ROI)-based techniques to measure nonuniformity, minimum signal-to-noise ratio (SNR), number of anomalous pixels, and modulation transfer function (MTF). This study evaluated the effects of ROI size and layout on the image metrics by using four different ROI sets, assessed result uncertainty by repeating measurements, and compared results with two commercially available quality control tools, namely the Carestream DIRECTVIEW Total Quality Tool (TQT) and the GE Healthcare Quality Assurance Process (QAP)...

Diagnostic X-ray imaging depends on the maintenance of image quality that allows for proper diagnosis of medical conditions. Maintenance of image quality requires quality assurance programs on the various X-ray modalities, which consist of projection radiography (including mobile X-ray units), fluoroscopy, mammography, and computed tomography (CT) scanning. Currently a variety of modality-specific phantoms are used to perform quality assurance (QA) tests. These phantoms are not only expensive, but suitably trained personnel are needed to successfully use them and interpret the results...

Tuberculosis is over-represented in hard-to-reach (underserved) populations in high-income countries of low tuberculosis incidence. The mainstay of tuberculosis care is early detection of active tuberculosis (case finding), contact tracing, and treatment completion. We did a systematic review with a scoping component of relevant studies published between 1990 and 2015 to update and extend previous National Institute for Health and Care Excellence (NICE) reviews on the effectiveness of interventions for identifying and managing tuberculosis in hard-to-reach populations...

BACKGROUND: Mobile-bearing total ankle replacement (TAR) enables motion at the tibial implant-polyethylene insert interface. This motion could lead to coronal translation of the talus relative to the tibia and may affect radiographic outcome. We aimed to assess the translation of the talus before and after mobile-bearing TAR to determine whether translation of the talus after TAR is associated with coronal plane alignment of the lower limb and hindfoot as well as to investigate the complications associated with talar translation...

Fibrous dysplasia is a bone disease characterized by abnormal differentiation of fibrous tissue in the bones; it is often asymptomatic. It may affect one bone (monostotic) or several bones (polyostotic). The monostotic form primarily affects the ribs, but hardly ever affects the hand. It is important to make the differential diagnosis with malignant bone tumors. This article describes the treatment and outcome of a rare case of a patient admitted with a history of tumor growth in the right hand, diagnosed as fibrous dysplasia of the right second metacarpal...

BACKGROUND: Granulocyte-colony stimulating factor (G-CSF) is widely used to mobilize peripheral blood stem cells (PBSCs) in healthy donors. A few reports have shown that some healthy donors developed acute respiratory distress syndrome or capillary leak syndrome after more than several rounds of G-CSF administration or leukapheresis. CASE REPORT: We report the case of a healthy donor for allogeneic stem cell transplantation who developed severe hypoxemia 1 h after only the first administration of G-CSF...
