INTRODUCTION Gradenigo's syndrome is nowadays a rare condition characterized by a triad of otorrhea, facial pain with trigeminal nerve involvement and abducens nerve palsy. Most cases are caused by medial extension of acute otitis media into a pneumatized petrous apex and surgical drainage is usually the treatment of choice. We present a case highlighting the pathological mechanism of this dise...

We present a very rare case of a 29-month-old boy with acute onset right abducens nerve palsy complicated by inferior petrosal sinus septic thrombosis due to mastoiditis without petrous apicitis. Four months after mastoidectomy, the patient fully recovered from an esotropia of 30 prism diopters and an abduction limitation (-4) in his right eye.

The main goal of this paper is to provide routing– table-free online algorithms for wireless sensor networks (WSNs) to select cost (e.g., node residual energies) and delay efficient paths. As basic information to drive the routing process, both node costs and hop count distances are considered. Particular emphasis is given to greedy routing schemes, due to their suitability for resource constra...

We report a case of a non-Hodgkin's lymphoma in a young woman presenting with an abdominal mass and an unusual instance of cranial nerve palsies mimicking Gradenigo's syndrome. This condition is characterized by a triad of otorrhea, facial pain and diplopia, related to otitis media in the pre-antibiotic era. Incomplete and atypical clinical features of Gradenigo's syndrome have been described a...

INTRODUCTION Traditional management of Gradenigo's syndrome requires aggressive and radical surgery without any attempt to preserve hearing. Recent reports, however, describe a successful outcome after conservative surgical intervention without labyrinthectomy. A similar outcome has also been reported in patients who were only prescribed with antibiotics and did not undergo myringotomy. CASE ...

Otits media is a common problem. Some of its complications that were seen frequently in the preantibiotic era are rare today. We report a case of an 8 year boy who presented with earache, retro-orbital pain and diplopia secondary to a sixth nerve palsy--Gradenigo's syndrome. In this syndrome infection from the middle ear spreads medially to the petrous apex of the temporal bone. Work-up include...

Recent experiments by Fischetti and Lodi show that the first Chvátal closure of a pure integer linear program (ILP) often gives a surprisingly tight approximation of the integer hull. They optimize over the first Chvátal closure by modeling the Chvátal–Gomory (CG) separation problem as a mixed integer linear program (MILP) which is then solved by a generalGérard Cornuéjols was supported in part...
