Although it is thought that obstructive sleep apnea (OSA) is worse during rapid eye movement (REM) sleep than in non-REM (NREM) sleep there are some uncertainties, especially about apnoe-hypopnoe-index (AHI). Several studies found no significant difference in AHI between both sleep stages. However, REM sleep is associated more with side sleeping compared to NREM sleep, which suggests that body ...
OBJECTIVES To compare differential renal perfusion in various body positions in healthy volunteers, to help postulate factors responsible for recurrent unilateral stone formation. METHODS Ten volunteers with normal renal function and no history of urinary disease were evaluated with diuretic renography using mercaptoacetyl-triglycine. Scintigraphy was performed 1 week apart in each of three t...
Aiming at the problem that the traditional control methods can’t satisfactorily complete the trajectory tracking task, so a multi point preview control method based on automobile driving is designed for the motion control of four-wheel drive omni-directional mobile robot. Lateral position error and curvature of each preview point are calculated based on the robot’s lateral position error model....
implant-supported craniofacial prostheses are made to restore defective areas in the face and cranium. this clinical report describes a technique for fabrication of an orbital prosthesis with three adjacent implants in the left lateral orbital rim of a 60-year-old woman. selection of appropriate attachment system (individual magnetic abutments versus bar-clip attachment) for implant-supported o...
Background: During general anesthesia in patients with mediastinal mass compression effect on the heart, great intra thoracic vessels, or tracheal tree can lead to decrease venous return, cardiovascular collapse or tracheal obstruction. These complications may be worsened after induction of general anesthesia or prescribing muscle relaxants. Case report: A twenty one years old female with huge...
Since the introduction of the beach chair position for shoulder arthroscopy, orthopaedic surgeons have debated whether the beach chair or lateral decubitus is superior. Most surgeons use the same patient position to perform all of their arthroscopic shoulder procedures, regardless of the pathology. Each position has its advantages and disadvantages. The evidence regarding the efficiency, effica...
OBJECTIVE To perform a retrospective radiographic assessment of the reduction and implant position in the femoral head in patients with pertrochanteric fractures treated with cephalomedullary nailing in the lateral position versus traction table. METHODS Radiographs of patients with pertrochanteric fracture of the femur treated with cephalomedullary nailing in the lateral position and tractio...
Stereotactic vacuum-assisted breast biopsy (VAB) has been used to evaluate microcalcifications or non-palpable breast lesions on mammography. Although stereotactic VAB is usually performed in a prone or upright position, an expensive prone table is necessary and vasovagal reactions often occur during the procedure. For these reasons, the lateral decubitus position can be applied for stereotacti...
