Search for di-muon decays of a low-mass Higgs boson in radiative decays of the Gamma(1S)
We search for di-muon decays of a low-mass Higgs boson (A(0)) produced in radiative Gamma(1S) decays. The Gamma(1S) sample is selected by tagging the pion pair in the Gamma(2S, 3S) -> pi(+)pi(-) Gamma(1S) transitions, using a data sample of 92.8 x 10(6) Gamma(2S) and 116.8 x 10(6) Gamma(3S) events collected by the BABAR detector. We find no evidence for A(0) production and set 90% confidence level upper limits on the product branching fraction B(Gamma(1S) -> gamma Lambda(0)) x B(Lambda(0)->mu(+)mu(-)) in the range of (0.28 - 9.7) x 10(-6) for 0.212 gamma Lambda(0), Lambda(0) -> mu(+)mu(-) to set limits on the effective coupling of the b quark to the Lambda(0).
Retropharyngeal abscess from fishbone in adult immunocompetent host presenting as acute thyroiditis
Retropharyngeal abscesses (RPA) are rare in adults. We report a case of a healthy adult with RPA presenting with clinical symptoms of acute thyroiditis. A 37-yr-old female presented with a painful mass in the anterior region of the neck, sore throat, mild fever and dysphagy for liquids and solids. Neck emergency US dis-closed normal thyroid ventrally displaced by a huge retropharyngeal hypoechoic mass. Direct laryngoscopy revealed erythema of the posterior pharyngeal wall with bulges (8 cm) preventing the correct visualization of the glottic plane. CT confirmed the pres-ence of retropharyngeal abscess and laryngoscopic drainage was performed. The pa-tient was discharged on 11th post-operati…
