Current treatment for osteoid osteomas is usually surgical excision of the nidus. We treated 18 patients with osteoid osteoma by percutaneous thermocoagulation of the nidus under computed-tomography guidance. The procedure was technically successful in all cases and there were no complications. Patients were discharged on the following morning and resumed(More)
Thirty-nine patients with unstable pelvic fractures were analysed retrospectively. The mean age of the group was 41 years (range 15-77). Of these cases 35 had sustained high energy trauma. The mean Hospital Trauma Index-Injury Severity Score of the population was 32 (16-66). Nine cases were haemodynamically unstable on admission. The type of unstable pelvic(More)
OBJECTIVE The purpose of this study was to evaluate the efficacy of sonography in our algorithm when differentiating patients with blunt abdominal trauma who need immediate surgery from patients who would benefit from further diagnostic workup or who need no treatment. SUBJECTS AND METHODS We performed abdominal sonography as the primary screening tool in(More)
The purpose of this study was to evaluate the ability of abdominal ultrasound (US) to detect intra-abdominal injuries that required surgical repair. We therefore retrospectively reviewed 353 patients with nontrivial blunt abdominal trauma. All patients underwent abdominal evaluation as part of our routine trauma protocol within the first minutes of arrival(More)

OBJECTIVE The purpose of this study was to evaluate the indication for routine cervical spine radiography in trauma patients. METHODS Prospective analysis of radiologic and clinical findings was performed during a 5-year period. Patients suitable for a clinical decision rule were reviewed separately. RESULTS Of the 1,757 consecutive patients included in(More)
We describe a case of a 6-year-old girl with a posterolateral elbow dislocation and a concomitant fracture of the lateral humeral condyle. After reduction of the dislocation, the fracture was diagnosed and treated by open reduction and fixation, with a good functional result. In doubtful cases, oblique, heterolateral, and varus stress films, or even(More)
We use N -body simulations to measure mass functions in flat cosmological models with quintessence characterized by constant w with w = −1, −2/3 and −1/2. The results are compared to the predictions of the formula proposed by Jenkins et al. at different redshifts, in terms of FOF masses as well as Abell masses appropriate for direct comparison to(More)
Polytrauma is a life-threatening entity that requires immediate action by all specialties involved. Upon arrival in the hospital, the patient will be seen and managed primarily by three groups of medical personnel: (a) surgeons (trauma specialists), (b) intensive care specialists, and (c) radiologists. The usual medical approach within the first minutes to(More)
Ultrasound is one of several modalities useful in the work-up of an injured patient. It is a bedside technique which is quick, economical and highly reliable in filtering out the patients who are in urgent need of laparotomy. For the moment, this is the prime and only function of this modality. The US examination can and should be repeated with a very low(More)
