wilms' tumor (wt) is the most common primary renal tumor in children. common sites of metastases are lungs, liver and regional lymph nodes. testicular and paratesticular metastasis due to wt have been reported but it is extremely rare. we report a 33-month -old male with bilateral wt and metastasis to right spermatic cord.

     Multiple sclerosis (MS) is an inflammatory, demyelinating, neurodegenerative disorder of the central nervous system (CNS) of unknown etiology. Isolated oculomotor nerve palsy is found rarely in children with MS. We present a case of MS in 10-year-old boy, who had bilateral ptosis associated with medial gaze restriction. The extraocular muscle examination demonstrated bilateral adduction pa...

conclusions in simultaneous bilateral patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. however, personality of the fracture determines salvage versus sacrifice of the patella. case presentation we report a rare case of isolated, traumatic bilateral patella fracture with unusual fracture patterns and briefly r...

This paper presents a quantitative comparison framework for bilateral teleoperation systems which have different dynamic characteristics and sensory configurations for a given Task Dependant Performance Objective. μ-synthesis is used to develop the framework since it can efficiently treat systems containing uncertainties and disturbances. The framework consists of i) a feasibility test, and ii)...

This paper focuses on the mechanism design of a novel compact dexterous hand of 3 fingers, 9 joints and 7 DOF (degrees of freedom). The technology of single-motor actuation is used and a kind of compact bilateral clutch is designed to reduce the size of actuation and control part of the hand. Different from most dexterous hand designs, no lengthy tendons are needed in this design since the actu...
