Computer-based simulators offer users the opportunity to learn and practice surgical skills through repeated exercises within safe and realistic learning environments. This paper reports the development of a da Vinci Surgical System simulator, including the creation of a geometrical and kinematic model of the da Vinci system. The SensAble Phantom 3D(More)
For the operation planning of robotically assisted laparoscopic surgery, the most critical issues are the trocar port placement in the patient's body (incision entry port for intervention) and the pose selection of the robot (docking of the robot). These significantly affect the robot's dexterity, manipulability, reachability, and visibility, which are(More)
BACKGROUND Clarithromycin is frequently used to treat community-acquired pneumonia in elderly persons. Like erythromycin, it may interact with other drugs by interfering with metabolism by cytochrome P450 enzymes and with the P-glycoprotein transporter system. Colchicine, used for treatment of acute gout and for prophylaxis, may cause bone marrow toxicity.(More)
OBJECTIVES This review identified reports of acupuncture for childhood nocturnal enuresis, with the aim of ascertaining whether acupuncture is efficacious and or better than standard therapy for treating enuresis. MATERIALS AND METHODS Studies of children of either gender <18 years of age who received acupuncture treatment for nocturnal enuresis, were(More)
Severe acute respiratory syndrome (SARS) is a newly discovered infectious disease caused by a novel coronavirus. During the community outbreak in Hong Kong, 5 liveborn infants were born to pregnant women with SARS. A systematic search for perinatal transmission of the SARS-associated coronavirus, including serial reverse transcriptase-polymerase chain(More)
Eleven survivors of pelvic rhabdomyosarcoma underwent bladder function studies and upper urinary tract evaluation at a mean of 6.6 years after completion of therapy, which included a conservative, bladder-sparing surgical policy. Primary tumour sites were: bladder base/prostate, 6; bladder dome, 1; vagina, 2; and pelvic side wall, 2. Seven children (five(More)
The nature of the action of the vesicoureteric junction (VUJ) in humans is still controversial. We were interested in the reasons why the jet consists of several peaks. We hypothesised that the modification of the jet into a variable number of peaks is the result of an active sphincter mechanism at the VUJ. A total of 1,010 subjects of all ages and both(More)
Roles of c-aminobutyric acid (GABA) antagonists on the chick model of form-deprivation myopia (FDM) were investigated. Bicuculline (GABA A) or TPMPA (GABA A0r) was injected intravitreally (1 or 10 mg=mL) into the right eyes of chicks with or without 10 FDM for 13 days. The contralateral eyes served as the control. The eye weight (EW), equatorial diameter(More)
PURPOSE Our previous results revealed a positive correlation between bladder dysfunction and cortical arousals in children with enuresis. This finding implied an interrelationship between bladder dysfunction and brainstem dysfunction. Thus, we used an animal model to characterize brainstem functional changes in response to altered bladder function. (More)
