BACKGROUND: Spontaneous pneumomediastinum (SPM) is classified as free air in the mediastinum in the absence of any precipitating cause. It is relatively uncommon, and the clinical significance and risk associated with SPM is not well understood and has not been widely documented in the literature. Our goals were to determine the outcomes of patients who presented with SPM and to determine predictors of severe pathology associated with SPM. METHODS: From 2004 through 2013, a retrospective review was conducted of patients who presented with SPM to our institution...

Early diagnosis and immediately started appropriate treatment are mandatory for the prevention of radiographic progression, functional disability and unfavourable disease outcome in rheumatoid arthritis (RA). The current classification criteria for RA include two different types of biomarkers representing inflammatory processes, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) or immune processes including autoantibodies, such as rheumatoid factor (RF) and antibodies against citrullinated proteins (ACPA)...

Importance: Pharyngocutaneous fistula formation is an unfortunate complication after salvage laryngectomy for head and neck cancer that is difficult to anticipate and related to a variety of factors, including the viability of native pharyngeal mucosa. Objective: To examine whether noninvasive angiography with indocyanine green (ICG) dye can be used to evaluate native pharyngeal vascularity to anticipate pharyngocutaneous fistula development. Design, Setting, and Participants: This cohort study included 37 patients enrolled from June 1, 2013, to June 1, 2016, and follow-up was for at least 1 month postoperatively...

A 50-year-old male was admitted to Intensive Care Unit with head and chest injury needed multiple central venous catheter (CVC) for the long-term intravenous access. Right internal jugular vein was cannulated uneventfully, and the tip of CVC was confirmed in the chest radiograph along the right border of the mediastinum. After few days, left subclavian vein was cannulated and the procedure was uneventful. However, the postprocedure Chest X-ray showed the CVC along the left border of mediastinum rather than the right border...

A 4-year-old intact female, mixed breed dog was presented with a complaint of dyspnea. Clinical examination revealed symptoms related to disease of the upper airways. Radiographic findings were consistent with tracheal collapse associated with anomalies involving the seventh cervical vertebra and the first ribs bilaterally. Radiographs were highly suggestive of cervical ribs; computed tomography and ultrasound examination allowed complete characterization and better localization of the anomalies with relationship to the adjacent muscle and vasculature...

BACKGROUND: Osteoporotic vertebral fractures (VFs) are often misdiagnosed because asymptomatic and occurring in the absence of specific trauma. Further, diagnostic assessment of VFs may be suboptimal. AIM OF THE STUDY: To assess the misdiagnosis of vertebral fractures on local radiographic readings in the cohort of patients enrolled in the POINT study. METHODS: We enrolled hospitalised patients, admitted for any cause to the Internal Medicine Units of 37 hospitals participating to the cross-sectional previously published POINT study...

Sarcoidosis is a multiorgan inflammatory disease that rarely involves the musculoskeletal system. A typical radiographic presentation is only noted with phalangeal lesions in the hands and feet, and other skeletal sites of sarcoidosis are a diagnostic imaging challenge [1]. We describe two cases of patients with sarcoidosis in whom pathologic bone marrow lesions were diagnosed on MRI scans. The magnetic resonance findings were non-specific and metastatic lesions or multiple myeloma were suspected. The case analysis serves to point to limitations of imaging studies in diagnosing bone sarcoidosis and underline the importance of cooperation between the radiologist and the clinician...

Mycobacterial infections are of primary health concern in NHP colonies in biomedical research. NHP are constantly monitoredand screened for Mycobacterium spp. We report 6 Chinese-origin rhesus macaques infected with Mycobacterium kansasii thatexhibited positive tuberculin skin tests in the absence of disease. Two of these macaques were being used for research purposes;the remaining 4 macaques were residing at the contract quarantine company. Histopathology and acid-fast staining of fixed tissues from all macaques showed that all were free of disease...

BACKGROUND: Simple bone cysts (SBC) have been documented to occur in adults with closed physeal plates, most commonly affecting the calcaneus in this patient subset. Although most authors theorize an association to trauma, etiology of simple bone cysts remains an enigma up to now. CASE PRESENTATION: A 26-year-old kickboxing coach sought consult for a painful right shoulder which on radiographs and magnetic resonance (MR) imaging showed a proximal humeral lesion with signs of ossification...

BACKGROUND: It is known that not all chiropractors follow mainstream guidelines on the use of diagnostic ionising radiation. Various reasons have been discussed in the literature, including using radiography to screen for congenital anomalies, to perform postural analysis, to search for contraindications to spinal manipulation, and to document chiropractic subluxations, i.e., tiny anatomical displacements of vertebrae thought to affect nerves and health. The visualisation of subluxations was the reason chiropractic first adopted the x-ray in 1910...

BACKGROUND: The use of a bronchial genomic classifier has been shown to improve the diagnostic accuracy of bronchoscopy for suspected lung cancer by identifying patients who may be more suitable for radiographic surveillance as opposed to undergoing invasive procedures. Our objective was to assess the cost-effectiveness of bronchoscopy plus genomic classifier versus bronchoscopy alone in the diagnostic work-up of patients at intermediate risk for lung cancer. METHODS: A decision-analytic Markov model was developed to project the costs and effects of two competing strategies, using test performance from the AEGIS-1 and AEGIS-2 studies...

REVIEW
Samuel Nurko
Gastrointestinal motility disorders in the pediatric population are common and can range from benign processes to more serious disorders. Performing and interpreting motility evaluations in children present unique challenges. There are primary motility disorders but abnormal motility may be secondary due to other disease processes. Diagnostic studies include radiographic scintigraphic and manometry studies. Although recent advances in the genetics, biology, and technical aspects are having an important impact and have allowed for a better understanding of the pathophysiology and therapy for gastrointestinal motility disorders in children, further research is needed to be done to have better understanding of the pathophysiology and for better therapies...

PURPOSE: Preoperative screening in hip fracture patients is vital to minimize perioperative complications. Preoperative chest radiographs (POCR) are performed in many hip fracture patients. Earlier research showed that few POCR abnormalities influence perioperative policy. However, no studies in nonelective patient with a specific surgical conditions have been performed. With many hip fractures per year worldwide, a significant cost reduction could be made by performing selective POCR without compromising the quality of care...

OBJECTIVES: To define clinical correlates of low voltage isolated to precordial leads on the surface electrocardiogram (ECG). INTRODUCTION: Low voltage (V) on the ECG is defined as QRS V<5mm in all limb leads and <10mm in all precordial leads. The diagnostic use of ECGs with low voltage isolated to the precordial leads with normal limb lead voltages is unclear. METHODS: Twelve-lead ECGs with QRS V>5mm in one or more limb leads and <10mm in all precordial leads were collected...

BACKGROUND: In children, non-fractured wrists generally need no treatment and those that are fractured may only require a 3-week cast without any clinical follow-up. The ability to perform a point-of-care triage decision if radiographs are needed could improve patient flow and decrease unnecessary radiographs. The aim of this study was to evaluate the role of ultrasound (US) as a point-of-care triage tool for pediatric wrist injuries with limited training. METHODS: Physicians with no previous US experience attended a 1...
