Headache is a common symptom, with a lifetime prevalence of over 90% of the general population in the United Kingdom (UK). It accounts for 4.4% of consultations in primary care and 30% of neurology outpatient consultations. Neuroimaging is indicated in patients with red flag features for secondary headaches. The guidelines recommend CT or MRI scan to identify any intracranial pathology. We pres...

Neuroblastoma is the most frequent solid extra-cranial malignant tumor in children. A proper staging of the disease allows the selection of the appropriate treatment, including the surgical approach. The present review aims to discuss and illustrate the role of computed tomography (CT) and magnetic resonance (MRI) in the differential diagnosis of the retroperitoneal or mediastinal masses, prior...

Extracting and encoding clinical information captured in free text with standard medical terminologies is vital to enable secondary use of electronic medical records (EMRs) for clinical decision support, improved patient safety, and clinical/translational research. A critical portion of free text is comprised of 'summary level' information in the form of problem lists, diagnoses and reasons of ...

OBJECTIVE To describe factors associated with computed tomography (CT) use for children with minor blunt head trauma that are evaluated in emergency departments. STUDY DESIGN Planned secondary analysis of a prospective observational study of children <18 years with minor blunt head trauma between 2004 and 2006 at 25 emergency departments. CT scans were obtained at the discretion of treating c...

The purpose of this cross-sectional study was to measure imaging utilization rates and the negative appendectomy rate (NAR) in metropolitan Seoul, Korea. The study included 2321 adolescents and adults (≥ 15 yr; median [interquartile range] age, 37 [27-50] yr; 46.7% female) undergoing appendectomy in 2011 at eight tertiary and three secondary hospitals. Imaging utilization rate was 99.7% (95% co...

heparin is frequently used in different clinical settings to reduce the coagulating ability of the blood. because of probable adverse effects owing to heparin therapy and regarding variability of patients’ responses to heparin, which make it very unreliable, it seems prudent to monitor meticulously its effects on the human body. there are a lot of laboratory tests to watch its effects on the bo...

BACKGROUND In women, anorectal infections with Chlamydia trachomatis (CT) are about as common as genital CT, yet the anorectal site remains largely untested in routine care. Anorectal CT frequently co-occurs with genital CT and may thus often be treated co-incidentally. Nevertheless, post-treatment detection of CT at both anatomic sites has been demonstrated. It is unknown whether anorectal CT ...

Retropharyngeal abscess is a rare but serious infection, in children, it often secondary to upper respiratory tract infections.We report the case of an 18-month-old infant admitted emergencies for acute febrile torticolis. A computed tomographic (CT) scan with contrast agent injection revealed collection retropharyngeal space; management consisted triple antibiotic therapy and transoral drainag...

The influence of calcitonin (CT) on various stages of bone formation was investigated. A demineralized collagenous bone matrix-induced bone forming system in rats was used to temporally segregate chondrogenesis and osteogenesis. Administration of CT (15 Medical Research Council Units [MRCU]) daily) at the initiation of matrix-induced bone formation (BF) resulted in a 76% stimulation of BF as me...

Recent studies have identified numerous pathologies in the cranial domes of pachycephalosaurid dinosaurs. These utilized CT images to identify secondary woven bone and sclerosis associated with pathologies. features were critical for diagnosing post-traumatic osteomyelitis, which supported head-butting behaviour hypothesis. However, conventional image resolution may not be sufficient or sclerot...
