Mobile radiography

Ahmed Alhilou, Hannah P Beddis, Alan J Mighell, Kathryn Durey
Dentin dysplasia(DD) is a rare autosomal dominant disorder associated with disturbance of the dentin. While the crowns appear clinically normal, on radiography, the pulp spaces appear partially or completely obliterated, with short blunted roots, and multiple periapical radiolucencies affecting the apparently sound teeth. Clinical signs include spontaneous abscess formation or increased tooth mobility which can lead to exfoliation. DD can therefore have a significant impact on the patient's dentition, and treatment is often challenging...

In ankylosing spondylitis (AS), structural damage that occurs as a result of syndesmophyte formation and ankylosis of the vertebral column is irreversible. Structural damage is currently assessed by conventional radiography and scoring systems that reliably assess radiographic structural damage are needed to capture the differential effects of drugs on structural damage progression. The validity of the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) as a primary outcome measure in evaluating the effect of AS treatments on radiographic progression rates was assessed in this review...

Case summary: A 1-year-old male neutered mixed breed cat presented with a 2 month history of inability to fully open the mouth when yawning and decreased ability to prehend food. Physical examination revealed severe bilaterally symmetrical masticatory muscle atrophy, a restricted vertical mandibular range of motion of 11-12 mm, and a normal body condition score. Skull radiography was normal. A canine ELISA system against unique masticatory muscle fibers (2M antibody titer), was positive at 1:1000 (reference interval <1:100 in dogs, and was <1:100 using serum from five archived normal cats), indicating the presence of cross-reacting antibodies...

INTRODUCTION: Patient reported outcome scores may be the preferred method to assess clinical results following acetabular fracture fixation. However, in current acetabular fracture research, there is a scarcity of studies using these scores and long-term follow-up is lacking. The aim of this study is to describe long-term patient reported outcomes following acetabular fracture surgery and to evaluate the association between reduction quality and these outcome measures. METHODS: Patients who received operative fixation for acetabular fractures (1992-2012) were sent questionnaires (short musculoskeletal functional assessment (SMFA) function index and short form (SF)-12), which was returned by 106 patients (22%) (mean age 51 years, 74% male)...

INTRODUCTION: Duchenne muscular dystrophy (DMD) is an x linked recessive disorder. Long term prognosis is ominous, with development of respiratory distress and cardiomyopathy in advanced stage of the disease and expected death in the teens-to-mid 20s due to respiratory or cardiac failure. Peri-operative management of this patients is challenging due to difficult airway anatomy (macroglossia, limited neck and mandibular mobility). Additionally, they are at risk of developing malignant hyperthermia, rhabdomyolysis and hyperkalemic cardiac arrest when exposed to halogenated inhalational anaesthetics and depolarizing muscle relaxants...

BACKGROUND: In order to meet the future challenges posed by ageing populations, new technology, telemedicine and a more personalized healthcare system are needed. Earlier research has shown mobile radiography services to be highly beneficial for nursing home residents in addition to being cost-effective. Despite the benefits, mobile radiography services are uncommon in Europe and Norway. The purpose of this study was to explore success criteria and barriers in the process of implementing mobile radiography services, from the point of view of the hospital and municipal managers...

PURPOSE: To optimise the radiation dose and image quality for chest radiography in the neonatal intensive care unit (NICU) by increasing the mean beam energy. METHODS: Two techniques for the acquisition of NICU AP chest X-ray images were compared for image quality and radiation dose. 73 images were acquired using a standard technique (56 kV, 3.2 mAs and no additional filtration) and 90 images with a new technique (62 kV, 2 mAs and 2 mm Al filtration). The entrance surface air kerma (ESAK) was measured using a phantom and compared between the techniques and against established diagnostic reference levels (DRL)...

BACKGROUND CONTEXT: Patients with infective spondylodiscitis who failed conservative treatment are generally indicated for open surgery. However, some patients are poor candidates for standard surgery, hence the need to evaluate less invasive approaches. Good outcomes were previously reported for percutaneous suction aspiration and drainage (PSAD) in the treatment of infective spondylodiscitis resistant to conservative therapy. We recently extended the surgical approach of PSAD to allow drainage of paravertebral or epidural abscesses in patients with progressive infective spondylodiscitis...

BACKGROUND: The anterior drawer test is traditionally used to assess ankle instability, but we believe that there is room for a small but effective improvement by adding digital palpation of the talus. We aimed to determine the accuracy of anterolateral talar palpation (ATP) in the diagnosis of ankle instability by comparing it with the traditional anterior drawer test. METHODS: Fourteen symptomatic and 10 asymptomatic patients were examined for excessive mobility through comparison of both ankles by two blinded orthopedic surgeons, each one using one of the above-mentioned tests...

Introduction: Odontoideum bone or the mobile odontoid process is one of the rarest malformations of the cervico-occipital hinge. It exposes to the atlo-axial instability and to the risk of bulbo-medullary compression threatening then the vital and functional prognosis. We report the case of a 16-year-old patient who was the victim of a raod accident resulting in acervical spine injury. Radiological investigation found an odontoideum bone malformation associated with C1C2 dislocation. Case Report: A 16-year-old patient with no medical history had a road accident...

Chest wall ultrasound has been awarded little interest in the literature, with chest wall anatomy described only in limited extent. The objective of this study has been to discuss the methodology of chest wall ultrasound and the sonographic anatomy of the region to facilitate professional evaluation of this complex structure. The primarily used transducer is a 7-12 MHz linear one. A 3-5 MHz convex (curvilinear) transducer may also be helpful, especially in obese and very muscular patients. Doppler and panoramic imaging options are essential...
