PURPOSE Little data exists in the medical literature describing the response of patients with inflammatory bowel disease (IBD) to abdominal and pelvic irradiation. To clarify the use of this modality in this setting, this study assesses the short- and long-term tolerance of 28 patients with IBD to abdominal and pelvic irradiation. METHODS AND MATERIALS(More)
The capacity of an optical CDMA (OCDMA) network has traditionally been defined as the number of continuously transmitting circuits supported by the network. In this paper, we use teletraffic models to determine the teletraffic capacity of a circuit-switched OCDMA network where circuits carry bursty traffic. Our analysis is independent of the OCDMA(More)
A 38-year-old woman from Antigua had compressive optic neuropathy of the right eye caused by orbital involvement with sinus histiocytosis. There was also nasal sinus involvement and massive cervical lymphadenopathy resulting in radiographic compression of the airway and carotid sheath. Because of the compressive optic neuropathy and threat to the airway and(More)
PURPOSE This study analyzes the long-term outcome of patients with stage T4 colon cancer who receive postoperative irradiation. The purpose of the study is to define the potential role of this modality with current systemic therapies. PATIENTS AND METHODS A retrospective analysis was performed of 152 patients undergoing resection of T4 colon cancer(More)
OBJECTIVE To report the clinical and pathologic features of sarcomatous transformation of the skull with involvement of the orbit, in Paget's disease. DESIGN Interventional case report. PARTICIPANT An 83-year-old woman with Paget's disease who experienced progressive proptosis of the left eye. INTERVENTION Fine-needle aspiration biopsy of the orbital(More)
PURPOSE Choroidal detachment is a known complication of topical hypotensive agents when used to treat eyes sensitized by prior surgery. We document the abrupt development of an extensive choroidal detachment after initiation of dorzolamide therapy in a surgically untreated eye with primary open-angle glaucoma. DESIGN Observational case report. METHODS A(More)
We show how an eavesdropper with a small amount of knowledge about the traffic sent via a spectral-phase optical CDMA system with phase-scrambling can break the confidentially of certain systems within a few bit intervals. c © 2007 Optical Society of America OCIS codes: (060.4250) Networks; (060.4510) Optical communications Optical CDMA (OCDMA) [1] is a(More)
Pelizaeus-Merzbacher disease is an X-linked hypomyelinating leukodystrophy caused by mutations or rearrangements in PLP1. It presents in infancy with nystagmus, jerky head movements, hypotonia and developmental delay evolving into spastic tetraplegia with optic atrophy and variable movement disorders. A clinically similar phenotype caused by recessive(More)
