Thoracic surgery in United Arab Emirates.

The United Arab Emirates (UAE) has undergone a significant change in its population and economy in the last decades and in parallel its healthcare system has evolved rapidly to provide advanced, innovative and world-leading care. At the forefront of this revolution in healthcare is the development of a multidisciplinary multimodality thoracic service provision, offered at quaternary referral hospitals amalgamating academics, training, research and innovation. Previously, thoracic service care was limited to single providers at various public and private hospitals, usually performing lower complexity cases.

The effect of changing apical foramen diameter on regenerative potential of mature teeth with necrotic pulp and apical periodontitis.

Objective: The aim of the present study was to evaluate the regenerative potential of permanent necrotic mature teeth with different apical foramen diameters in comparison to conventional endodontic treatment.

The infected teeth were divided into six groups; conventional root canal treatment (RCT) group prepared up to apical preparation sizes #F3 ProTaper file, regenerative endodontic therapy (RET) groups; groups RET-F3, RET-F4, and RET-F5 where regenerative endodontic procedures were applied after apical preparation up to sizes #F3, F4, and F5 ProTaper file, respectively, control groups; and positive (P) and negative (N) groups included infected and healthy teeth respectively.

[Alopecia reconstruction by expansion after a scalp burn injury caused by Taser(®): a case report].

Background: Scarring alopecia resulting from burns may be difficult to treat and involves various plastic surgery techniques such as expanded scalp flaps.

Observation: Herein, we report the case of a 19-year-old male patient who suffered burning of the scalp with scarring alopecia following an attack with a Taser(®) electrical gun. Given the extent and site of alopecia, we decided to create a prosthesis by means of scalp expansion.

Dose reduction with adaptive bolus chasing computed tomography angiography.

Computed Tomography (CT) has become an effective diagnosis and evaluating tool in clinical; however, its radiation exposure has drawn great attention as more and more CT scans are performed every year. How to reduce the radiation dose and meanwhile keep the resultant CT images diagnosable becomes an important research topic. In this paper, we propose a dose reduction approach along with the adaptive bolus chasing CT Angiography (CTA) techniques, which are capable of tracking the contrast bolus peak over all the blood vessel segments during the CTA scan.

One year clinical outcomes of renal artery stenting: the results of ODORI Registry.

The safety, efficacy and long term clinical benefits of renal artery revascularization by stenting are still a matter of debate. The aim of our study was to define the safety and efficacy of renal artery stenting with the Tsunami peripheral stent (Terumo Corporation, Tokyo, Japan). The ODORI was a prospective, multicentre registry which enrolled 251 consecutive patients, (276 renal arteries) in 36 centres across Europe.

Gelatine sponge particles: handling characteristics for endovascular use.

Gelatin sponge particles have been used since the mid 1960's in interventional radiology. It had played an important role as a temporary occlusive agent in the past. Embolization has gained a widespread acceptance in interventional radiology leading to different innovative new agents.

Strategies for reduction of radiation dose in cardiac multislice CT.

Because cardiac computed tomography (CT) (mainly coronary CT angiography) is a very promising technique, used more and more for coronary artery evaluation, the benefits and risks of this new low-invasive technique must be balanced. Radiation dose is a major concern for coronary CT angiography, especially in case of repeated examinations or in particular subgroups of patients (for example young female patients). Radiation dose to patient tends to increase from 16- to 64-slice CT.

MDCT of the coronary arteries: feasibility of low-dose CT with ECG-pulsed tube current modulation to reduce radiation dose.

Objective: The objective of our study was to show the feasibility of coronary CT using low kilovoltage (80 kV) combined with ECG-pulsed tube current modulation in selected patients.

Conclusion: This study showed the combined effect of lowering the kilovoltage setting (80 kV) and using an automatic modulation technique (ECG-pulsed tube current modulation) for coronary CT. Radiation dose exposure can be reduced by up to 88% for slim patients without impairing image quality.

Low-kilovoltage multi-detector row chest CT in adults: feasibility and effect on image quality and iodine dose.

Purpose: To assess the feasibility of low-kilovoltage (ie, 80-kV) chest computed tomography (CT) protocols for adults and the effect of such protocols on image quality and iodine dose.

Materials And Methods: Preliminarily, 90 patients (30 women, 60 men; mean age, 59 years) requiring contrast material-enhanced chest CT were randomly assigned to one of three protocol groups: protocol A, with use of 80 kV and 135 mAs; protocol B, with use of 80 kV and 180 mAs; or the standard protocol, with use of 120 kV and 90 mAs. Contrast material injection protocols were standardized in all groups.
