This study was performed to elucidate the mechanism of improved oxygenation after surfactant replacement therapy in respiratory distress syndrome (RDS) of the newborn infants. In 26 newborns with RDS, end tidal-CO2 tension (PetCO2), arterial blood gas analysis and pulmonary function tests were measured at baseline, 30 min, 2 hr and 6 hr after surfactant(More)
Osteoma mostly begins from the compact iliac bone but can be occasionally observed in the maxillofacial region. In the maxillofacial region, osteoma most frequently invades the sinuses, particularly the frontal sinus. It rarely occurs in the mandible [3]. Various pathogenesis of osteoma have been proposed, including the developmental theory, the neoplastic(More)
Metastatic calcification is caused by abnormal calcium and/or phosphate metabolism. Idiopathic calcification occurs even in the absence of tissue damage or metabolic disorders. Moreover, calcification may also occur as a result of tissue damage or impaired mineral metabolism after medical interventions [2]. We experienced a case of an 18-year-old man who(More)
There are 2 predominant mechanisms that are used to explain the pathogenesis of orbital blowout fracture; these include hydraulic and buckling mechanisms. Still, however, its pathophysiology remains uncertain. To date, studies in this series have been conducted using dry skulls, cadavers, or animals. But few clinical studies have been conducted to examine(More)
