CONDENSING OSTEITIS OF THE CLAVICLE - MAGNETIC-RESONANCE-IMAGING AS AN ADJUNCT METHOD FOR DIFFERENTIAL-DIAGNOSIS
Condensing osteitis of the clavicle is a benign disorder leading to osteosclerosis of the medial end of the clavicle. The differential diagnosis between condensing osteitis of the clavicle and ischaemic necrosis of the medial clavicular epiphysis (Friedrich's disease), osteoid osteoma, and low grade osteomyelitis can be difficult. In the case history reported here, magnetic resonance imaging was a useful non-invasive procedure for the diagnosis of condensing osteitis of the clavicle

Thoracic sequelae after surgical closure of the patent ductus arteriosus in premature infants
Thirty-six children (median chronological age 6 years 1 month) who had undergone surgical closure of a patent ductus arteriosus through a left posterolateral thoracotomy in the neonatal period (median gestational age 32 weeks) were investigated prospectively with respect to anatomical and functional changes of the chest. At follow-up examination, residual or recurrent patent ductus arteriosus was not observed. Three patients had chronic bronchial obstruction. Two patients showed pathological musculoskeletal thoracic sequelae that did not require any treatment at the time of follow-up; persistence of immediate postoperative left phrenic palsy (n = 1) and thoracic scoliosis (n = 1). Twenty of the 27 patients in whom chest X-ray was performed had minor radiological skeletal anomalies in the form of rib deformation or fusion related to the thoracotomy, lesions which have a potential to induce thoracic scoliosis. Left shoulder elevation at chest X-ray and isolated left arm dysfunction at clinical examination were not observed. Despite the low incidence of scoliosis and the absence of left arm dysfunction observed at mid-term follow-up in our series, the incidence of minor rib deformations with a potential to induce severe anomalies such as scoliosis should motivate late follow-up examination at adolescence to definitively assess the prevalence of thoracic sequelae after surgical closure of the patent ductus arteriosus in premature infants
Searches for supersymmetry with the ATLAS detector using final states with two leptons and missing transverse momentum in root s=7 TeV proton-proton collisions
Results of three searches are presented for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons, e or mu. The analysis uses a data sample collected during the first half of 2011 that corresponds to a total integrated luminosity of 1 fb(-1) of root s = 7 TeV proton-proton collisions recorded with the ATLAS detector at the Large Hadron Collider. Opposite-sign and same-sign dilepton events are separately studied, with no deviations from the Standard Model expectation observed. Additionally, in opposite-sign events, a search is made for an excess of same-flavour over different-flavour lepton pairs. Effective production cross sections in excess of 9.9 fb for opposite-sign events containing supersymmetric particles with missing transverse momentum greater than 250 GeV are excluded at 95% CL For same-sign events containing supersymmetric particles with missing transverse momentum greater than 100 GeV, effective production cross sections in excess of 14.8 fb are excluded at 95% CL The latter limit is interpreted in a simplified electroweak gaugino production model excluding chargino masses up to 200 GeV, under the assumption that slepton decay is dominant.
