BACKGROUND We report our approach regarding the technique of endoscopic extraperitoneal radical prostatectomy (EERPE) and analyze the learning curve of two surgeons after thorough technical training under expert monitoring. The purpose of this study was to investigate the influence of expert monitoring on the surgical outcome and whether previous laparoscopic experience influences the surgeon's...

introduction: nowadays,  considerable developments  in  the field  of  radiotherapy have  been  achieved.  they  include  the  advances  made  in  the  equipments  and  treatment  planning  techniques  which  require  highly complex calculations. such achievements have made it possible to treat cancer patients not only  with  higher  radiation  dose  but  also  with  higher  precision  and  con...

ObjectiveTo identify women with high-risk endometrial cancers using expert and non-expert transvaginal ultrasonography (TVS) MRI.Study designMyometrial involvement was prospectively evaluated in patients atypical hyperplasia or cancer on ultrasound by non-experts at first visit (non-expert-TVS: n = 266) experts (expert-TVS: 188) second visit. MRI (n 175) performed when suspected non-expert-TVS....

The top-hat and watershed algorithms of mathematical morphology have been applied to detect automatically and segment microcalcifications on mammograms digitized to a pixel resolution of 40 microns using a CCD camera. The database comprised 38 cases from the breast assessment clinic in Liverpool. For all cases, both craniocaudal (CC) and lateral oblique (LO) views were available. 19 cases were ...

OBJECTIVE This study proposes a new approach that considers uncertainty in predicting and quantifying the presence and severity of diabetic peripheral neuropathy. METHODS A rule-based fuzzy expert system was designed by four experts in diabetic neuropathy. The model variables were used to classify neuropathy in diabetic patients, defining it as mild, moderate, or severe. System performance wa...

A 3-week-old infant awoke with a fever. He was taken to the doctor who noted that the child was irritable. The doctor took him to the hospital where a resident performed a spinal tap, started an intravenous (IV) line, and ordered antibiotics. The entire drama, from entering the doctor's office to infusion of ampicillin, took 2 hours. The doctor was sued for malpractice. Expert witnesses for the...

v. dannon showed that spherical curves in e4 can be given by frenet-like equations, and he thengave an integral characterization for spherical curves in e4 . in this paper, lorentzian spherical timelike andspacelike curves in the space time 41 r are shown to be given by frenet-like equations of timelike andspacelike curves in the euclidean space e3 and the minkowski 3-space 31 r . thus, finding...

Qualitative models provide the domain knowledge for qualitative reasoning systems, and the automatic generation of such models is an important knowledge acquisition task . Qualitative Simulation is a key qualitativ e reasoning technique . It is proposed that simulation systems like Kuipers ' QSIM [Kuipers 86] contain a powerful description language, based as they are on qualitativ e mathematics...
