ABSTRACT
BACKGROUND: The diagnosis of occult elbow fracture in children is often challenging due to equivocal or negative repeated radiographic findings. OBJECTIVE: To evaluate the potential diagnostic role of US in children who have sustained elbow trauma with an elbow joint effusion but no fracture seen on initial radiographs. MATERIALS AND METHODS: The study included 14 consecutive children (age range 5-15 years) with elbow trauma whose elbow radiographs showed an effusion without fracture who underwent emergency imaging (within the first 72 h) with US and MRI. The aim of US was to demonstrate a lipohaemarthrosis in relation to a cortical fracture. MR imaging was used as the reference to differentiate fracture from bone or muscle contusions. RESULTS: In seven children US demonstrated a lipohaemarthrosis, and MRI demonstrated a cortical fracture in all these children. Conversely, among the seven children with simple haemarthrosis seen on US, MRI did not identify a cortical fracture in six and demonstrated a cortical fracture in one. CONCLUSION: Posttrauma elbow joint effusion in children is not always related to a cortical fracture. US appears to be a reliable, accurate, widely available and effective low-cost tool in these cases. The diagnostic clue is the detection of a lipohaemarthrosis in the articular recess.

BACKGROUND: Stroke is the most common cause of permanent disability in Europe and is a major public health problem. A recent significant therapeutic advance is the administration of recombinant tissue plasminogen activator (rtPA) for cerebral infarcts within three hours of symptom onset. French guidelines limit its use to patients in specialized stroke units. There is only one stroke unit in the region of Aquitaine, in Bordeaux, 200 km from Pau and too far to transfer patients within the necessary time. With the collaboration of our colleagues in Bordeaux we decided to assess whether stroke thrombolysis could be feasibly and safely administered in our district general hospital. DESIGN: From September 2004 through August 2005, eligible patients received rtPA treatment in the emergency department. The National Institutes of Health Stroke Scale (NIHSS) was administered at admission, immediately after treatment, and 24 hours later. In January 2006, a prospective follow-up assessed the NIHSS, Modified Rankin Scale (MRS) and Barthel Index Score (BIS) for all subjects still alive and collected data about those who had died. RESULTS: In all, 553 patients were admitted for stroke: 306 had cerebral infarcts and 25 (8.1%) were treated by intravenous thrombolysis. The mean age of the patients who received thrombolysis was 67 years (range: 33-80), and the sex ratio was 4/1 (20 men and 5 women). Mean delay from symptom onset to treatment was 150 min (range 105-180). The median NIHSS score was 13 (range 8-22) at admission, 10 (range 0-22) after treatment, and 7 the next day (range 0-22). Two patients (8%) died during the acute phase. On January 2006, after a median follow-up of 11.6 months (range: 6-16), 18 (72%) patients were still alive: 13 (52%) with good outcomes (MRS, 0-1) and 3 severely disabled and institutionalized (BIS, 0-50). CONCLUSION: Our results show that thrombolysis is possible in Pau. The population in our catchment area has a good proportion of stroke patients eligible for thrombolytic treatment. Outcomes and mortality rate are consistent with experience elsewhere. The creation of a stroke unit should help improve prognosis while complying with management guidelines.
