Prediction of blood pressure using chest compression waveform during cardiopulmonary resuscitation.

Objectives: This study aimed to predict blood pressure during CPR using chest compression waveform information obtained from a CPR feedback device.

Methods: Quantitative data including chest compression waveforms from a CPR feedback device and the blood pressure measured by arterial cannulation in patients with cardiac arrest during CPR were used. Forty-one features to predict blood pressure were selected from chest compression waveform and demographic characteristics with neighborhood component analysis algorithm.

Cardiopulmonary resuscitation may cause paradoxical embolism.

This paper reports a case of paradoxical embolism of right heart thrombi visualized on transesophageal echocardiography during cardiopulmonary resuscitation (CPR). CPR may cause a right-to-left shunt by producing a sudden increase in right atrial pressure during the compression phase. In cardiac arrest patients with right heart thrombi who have received CPR, systemic embolization can occur owing to paradoxical embolism.

The clinical prognosis of implants that are placed against super-erupted opposing dentition.

Objectives: If teeth are missing, super-eruption of teeth in the opposing arch can occur in the area and can change the occlusal plane. When missing teeth are replaced with implants, the oral surgeon must determine whether or not the super-erupted teeth need to be treated in order to normalize the occlusal plane. In this study, we evaluated the clinical prognosis of dentition after implant placement and prosthetic treatment were completed in an occlusal plane altered by super-erupted teeth in the opposing arch without additional treatment of the super-erupted teeth.

A prospective study on the effectiveness of newly developed autogenous tooth bone graft material for sinus bone graft procedure.

Purpose: The purpose of this prospective study was to evaluate the effectiveness of newly developed autogenous tooth bone graft material (AutoBT)application for sinus bone graft procedure.

Materials And Methods: The patients with less than 5.0 mm of residual bone height in maxillary posterior area were enrolled.

Prospective observational study of the early loading of nanostructured calcium phosphate-coated tapered implants in the mandible and maxilla.

The purpose of this study was to evaluate the prospective clinical results of early loading. Implants were inserted in 11 maxillae (group I, 23 implants) and 12 mandibles (group II, 19 implants). Six months after prosthetic loading, several factors were investigated.

Reconstruction of Defect after Treatment of Bisphosphonate-related Osteonecrois of the Jaw with Staged Iliac Bone Graft.

Bisphosphonate is used widely for osteoporosis treatment, but a rising concern is the risk of osteonecrosis after long-term bisphosphonate use. Such cases are increasing, suggesting a need for research to prevent and treat bisphosphonate-related osteonecrosis of jaws. A 63-year-old female took bisphosphonate (Fosamax(®)) for four years for treatment of osteoporosis and stopped medication two months ago because of unhealed wound.

Effect of loading time on marginal bone loss around hydroxyapatite-coated implants.

Objectives: The objective of this study is compare the rate of marginal bone resorption around hydroxyapatite-coated implants given different loading times in order to evaluate their stability.

Materials And Methods: The study was conducted retrospectively for one year, targeting 41 patients whose treatment areas were the posterior maxilla and the mandible. Osstem TS III HA (Osstem Implant Co.

A retrospective study on the prognosis of single implant placed at the sinus bone graft site.

Objectives: The purposes of this study were to evaluate survival of single implants placed at the sinus bone graft site and to estimate influencing factors on the survival.

Study Design: The patients treated with single implant at the sinus bone graft site at Seoul National University Bundang Hospital from June 2003 to December 2006 were included. All the patients' data were collected by reviewing and analyzing dental record and radiograph.
