    Isolated hyoid bone fracture with pharyngeal laceration caused by road traffic accident: a case report and review of the literature
    (Galenos Yayincilik, 2010) Yilmaz, S.; Yildizbas, S.; Guclu, E.; Yaman, H.
    The isolated hyoid bone fracture because of blunt neck trauma other than strangulation is very rare. Diagnosis is difficult. We reported a case of 37-year-old woman who presented with an isolated hyoid bone fracture and laceration of the pharynx. Diagnosis was made by indirect flexible fiberoptic nasal pharyngoscopic examination and computed tomography scan of the neck. The patient was treated conservatively with success. A high degree of clinical suspicion is very important for an early diagnosis and successful management of this rare injury. The causes and management of different hyoid bone fractures due to road traffic accidents that occurred since 1954 are reviewed and discussed.

    Oxide ionic conductivity and crystallographic properties of tetragonal type Bi2O3 -based solid electrolyte doped with Ho2O3
    (2012) Bozoklu, M.; Turkoglu, O.; Yilmaz, S.; Ari, M.; Belenli, I.
    In the present work, the authors have investigated the binary system of (Bi2O3)1-x (Ho2O3) x. For the stabilisation of the tetragonal type solid solution, small amounts of Ho2O3 were doped into the monoclinic Bi2O3 via solid state reactions in the stoichiometric range 0?01?x?0?1. The crystal formula of the formed solid solution was determined as Bi(III) 4-4xHo(II)4xO6-2x Vo(2+2x) (where Vo is the oxide ion vacancy) according to the XRD and SEM microprobe results. In the crystal formula, stoichiometric values of x were 0?04?x?0?08, 0?03?x?0?09, 0?02?x?0?09 and 0?04?x?0?09 for annealing temperatures at 750, 800, 805 (quench) and 760{ring operator}C (quench) respectively. The four probe electrical conductivity measurements showed that the studied system had an oxide ionic type electrical conductivity behaviour, which is increased with increasing dopant concentration and temperature. The obtained solid electrolyte system has an oxygen non-stoichiometry characteristic, and it contains O2- vacancies, which have disordered arrangements in its tetragonal crystal structure. The increase in the amount of Ho2O3 doping and temperature causes an increasing degree of the disordering of oxygen vacancies and a decrease in the activation energy Ea. © 2010 Institute of Materials, Minerals and Mining.

    Sublingual and supraglottic haemorrhage as a complication of warfarin therapy
    (Medcom Ltd, 2011) Yaman, H.; Guven, D. G.; Kandis, H.; Subasi, B.; Alkan, N.; Yilmaz, S.
    Anticoagulant-induced haemorrhage in the upper airway is rare, but it can be life threatening if airway obstruction develops. Treatment is mainly conservative. Urgent control of airway and coagulopathy are the essential of management. Vitamin K1 or combination of fresh frozen plasma and vitamin K1 should be used for reversal of the coagulopathy. In this report, two elderly patients were reported to have oral anticoagulant (warfarin)-induced haemorrhage in the sublingual and supraglottic areas. (Hong Kong j.emerg.med. 2011; 18:177-181)
