To evaluate amblyopic scotoma and the most affected neural cells in suppressive phenomena, eight patients with deep amblyopia from strabismus (visual acuity of the amblyopic eye between 4/50 and 2/10) underwent a pattern electroretinogram (PERG), pattern visual evoked potential (VEP), and event-related potential (ERP) from visual stimuli, and computerized(More)
BACKGROUND Adjuvant chemoradiotherapy (CRT) is the standard treatment in Western countries for gastric cancer patients submitted to curative resection. However, the role of adjuvant CRT in gastric cancer treated with D2 lymphadenectomy has not been well defined. METHODS We conducted a retrospective study in patients with stage II to IV gastric(More)
OBJECTIVE We analyzed the surgical technique used for the replacement of damaged vertebral bodies of the thoracolumbar spine and the carbon fiber reinforced polymer (CFRP) cages that are used to replace the pathological vertebral bodies. We also evaluated the biomechanical properties of carbon composite materials used in spinal surgery. TECHNIQUE The(More)
Early receptor potentials were recorded by skin electrodes positioned at the inferior orbital margin in 32 patients with recent bullous retinal detachments and in nine patients with old, total retinal detachments. Results were compared to those obtained in a normative study performed on 200 healthy subjects. In patients with recent retinal detachments, no(More)
We report our results in nystagmus without null point surgery, utilizing a new technique consisting in the placement of a silicone encircling band around the globe over the four recti muscles, in the retroequatorial position. This method was tried only in nystagmus without null point and with both horizontal and vertical movements. We have not observed any(More)
The flash induced electroretinogram (ERG) and early receptor potential (ERP) were recorded in a population of patients with definite diagnosis of retinitis pigmentosa in the context of a study protocol including a complete diagnostic screening. ERPs were evoked by full-field 20-joule stimuli (5 stimuli at 10 min of interval in dark adaptation); recording(More)
