The aim of this study was to present our experience with primary breast angiosarcoma (PBA) by describing a large series of cases with an emphasis on clinicopathologic and radiologic correlations. Thirty-six cases of PBA diagnosed at our institution between 2006 and 2014 were retrospectively evaluated. All but one case occurred in women with a median age of 35.5 years. The majority of patients presented with a deeply located painless mass, whereas a minority manifested as diffuse enlargement or swelling of the breast...

We aimed to compare digital tomosynthesis (DTS) with radiographs for the assessment of spinal bone damage in patients with ankylosing spondylitis (AS). The study comprised 68 patients with AS who underwent both DTS and radiographs of the cervical and lumbar spine on the same day. Spinal bone damage was assessed using the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) and the presence of facet joint damage. The Wilcoxon signed-rank test and McNemar's test were used to compare spinal bone damage between the two modalities...

BACKGROUND: Purulent meningitis (PM) usually caused by a variety of pyogenic infection, is a kind of central nervous system infectious disease mostly common in children. It is easily misdiagnosed and its symptoms are varied. Excessive application of broad-spectrum antibiotics results in increased sickness and death of infants and young children. In this study, clinical data of 430 cases of PM in infants were analyzed to summarize the clinical experiences so as to achieve early diagnosis and early treatment of PM...

OBJECTIVES: Calcium pyrophosphate crystal deposition disease (CPPD) is common, yet prevalence and overall clinical impact remain unclear. Sensitivity and specificity of CPPD reference standards (conventional crystal analysis (CCA) and radiography (CR)) were meta-analysed by EULAR (published 2011). Since then, new diagnostic modalities are emerging. Hence, we updated 2009-2016 literature findings by systematic review and evidence grading, and assessed unmet needs. METHODS: We performed systematic search of full papers (PubMed, Scopus/EMBASE, Cochrane 2009-2016 databases)...

The burden of non-communicable diseases has increased exponentially over the past decade and they account for majority of the health-related morbidity and mortality worldwide. In line with this, the prevalence of chronic kidney disease (CKD) has been increasing over the years. CKD progresses through stages and it is well known that patients are more likely to die than to progress to end-stage renal disease. The presence of multiple classical and novel risk factors predisposes this group of patients to premature cardiovascular mortality...

Facial mimicry is the tendency to imitate the emotional facial expressions of others. Increasing evidence suggests that the perception of dynamic displays leads to enhanced facial mimicry, especially for happiness and anger. However, little is known about the impact of dynamic stimuli on facial mimicry for fear and disgust. To investigate this issue, facial EMG responses were recorded in the corrugator supercilii, levator labii, and lateral frontalis muscles, while participants viewed static (photos) and dynamic (videos) facial emotional expressions...

The stochastic resonance (SR) is a phenomenon in which adding a moderate amount of noise can improve the signal-to-noise ratio and performance of non-linear systems. SR occurs in all sensory modalities including the visual system in which noise can enhance contrast detection sensitivity and the perception of ambiguous figures embedded in static scenes. Here, we explored how adding background white pixel-noise to a random dot motion (RDM) stimulus produced changes in visual motion discrimination in healthy human adults...

BACKGROUND: The modalities of malaria transmission along the Thailand-Myanmar border are poorly understood. Here we address the relevance of using a specific Anopheles salivary biomarker to measure the risk of human exposure to anopheles bites. METHODS: Serologic surveys were conducted from May 2013 to December 2014 in 4 sentinel villages. Dried blood spots (n>9,400) were collected in filter papers among all inhabitants at baseline and then every three months up to 18 months...

Noninvasive ventilatory support (NVS) is sometimes reported as suboptimal in patients with neuromuscular disease (NMD). The reasons for this include inadequate ventilator settings and/or lack of interface tolerance. NVS has been used for many years in patients with NMD disorders as a viable alternative to continuous ventilatory support via a tracheostomy tube. The mouthpiece ventilation (MPV) is a ventilatory mode that is used as daytime ventilatory support in combination with other ventilatory modalities and interfaces for nocturnal NVS...

BACKGROUND AND PURPOSE: Glioblastoma and primary CNS lymphoma dictate different neurosurgical strategies; it is critical to distinguish them preoperatively. However, current imaging modalities do not effectively differentiate them. We aimed to examine the use of DWI and T1-weighted dynamic contrast-enhanced-MR imaging as potential discriminative tools. MATERIALS AND METHODS: We retrospectively reviewed 18 patients with primary CNS lymphoma and 36 matched patients with glioblastoma with pretreatment DWI and dynamic contrast-enhanced-MR imaging...

Transplant recipients are at an increased risk of malignant melanoma, a result of chronic immunosuppression. Ipilimumab is a newer biological agent targeting T lymphocytes to potentiate an immune response against melanoma, and the use of this agent results in a new adverse effect profile that the clinician must be aware of while a patient is on therapy. We report the case of a male renal transplant recipient who developed graft failure while treated with ipilimumab and minimal immunosuppressive therapy for metastatic ocular melanoma, with biopsy evidence of glomerulonephritis and acute rejection...

Low back pain is common and relates to a variety of overlapping pathologies. Within the last few decades, almost every medical imaging modality has been applied in the evaluation of low back pain. Imaging of the spine has a high priority in the assessment of patients with low back pain, who seem to expect such procedures to be undertaken. However, the majority of conventional imaging techniques do not have adequate precision to identify the primary source of pain. Not only can this be frustrating to both clinicians and patients, but importantly, inadequate correlation between imaging findings and symptoms hampers the ability of clinicians to devise a specific treatment plan for the patient...

Juvenile idiopathic arthritis (JIA) is a heterogeneous group of arthritides characterized by chronic synovial inflammation that can lead to structural damage. The main objective of JIA therapies is to induce disease control to avoid disability in childhood. The advances in therapeutic effectiveness have created a need to search for imaging tools that describe more precisely disease activity in children with JIA. Musculoskeletal ultrasound and magnetic resonance imaging have demonstrated to be more sensitive than clinical examination in early detection of synovitis...

Musculoskeletal regional pain syndromes often lead to patient referrals in general and rheumatological practice. Detailed history taking and clinical examination can in most cases reveal the cause for pain and direct the subsequent management of the conditions. Yet, when in doubt, imaging methods have to support the clinical assessment. This paper presents the underlying pathologies of the most frequently encountered regional pain syndromes and the role of musculoskeletal ultrasonography and magnetic resonance imaging in their visualization...

The increasing availability and improvement of imaging techniques are making a profound impact in the evaluation and management of patients with vasculitis, particularly for those with large vessel vasculitis, and will most likely play an ever more important role in the future. Deep, large vessels can be examined by CT or MRI, while ultrasound is the method of choice for the evaluation of superficial vessels (such as temporal, carotid, and axillary arteries). PET is very sensitive in detecting large vessel inflammation, but it does not delineate the vessel wall...

In daily clinical practice, conventional radiography is still the most applied imaging technique to supplement clinical examination of patients with suspected osteoarthritis (OA); it may not always be needed for diagnosis. Modern imaging modalities can visualize multiple aspects of the joint, and depending on the diagnostic need, radiography may no longer be the modality of choice. Magnetic resonance imaging (MRI) provides a complete assessment of the joint and has a pivotal role in OA research. Computed tomography (CT) and nuclear medicine offer alternatives in research scenarios, while ultrasound can visualize bony and soft-tissue pathologies and is highly feasible in the clinic...

While joint aspiration and crystal identification by polarizing microscopy remain the gold standard for diagnosing tophaceous gout, agreement among medical and ancillary health personnel examining synovial fluid using polarizing microscopy for the detection of monosodium urate (MSU) crystals appears to be poor. Imaging modalities, including conventional radiography (CR), ultrasonography (US), magnetic resonance imaging (MRI), and dual-energy computed tomography (DECT), have been found to provide information on the deposition of MSU crystals in tissues, and the consequences of such deposition...

REVIEW
Xenophon Baraliakos, Walter P Maksymowych
Magnetic resonance imaging (MRI) is the imaging modality of choice for diagnosing axial spondyloarthritis (SpA) when the pelvic radiograph is normal or equivocal. Subchodral bone marrow edema (BME) is the primary feature of early SpA, although structural changes, particularly erosions, may also be seen at an early stage. It is unclear whether incorporation of structural lesions enhances the classification performance of a positive MRI definition based on BME alone. Neither spinal imaging nor contrast-enhanced imaging are useful for routine diagnostic evaluation...

This review assesses the current status of end-of-life care based on large-scale, multiyear nationwide surveys of treatment modality, setting, and cost of care during terminal patients' last months of life. It shows that end-of-life care goals often remain suboptimal. Contributing factors include prioritized life preservation, uneven commitment to palliative care, few palliative care specialists, and perverse financial incentives that encourage costly interventions. Although not determinant per se, these factors coupled to doubts about what constitutes end-of-life can lead to overextended disease treatment and a late implementation of palliative care...
