We report the case of a 10-month old girl with a significant past medical history who presented for elective surgery with a new-onset fixed, dilated pupil. We briefly review the diagnostic approach to such patients and provide guidelines for managing these patients in the immediate preoperative setting.

Treatment of penetrating trauma to the neck is complex due to the vital structures involved. Early diagnosis of cervical injuries is essential, as any delay could lead to elevated morbidity and mortality. We present a case of a penetrating cervical wound with Horner syndrome and no associated vascular injury. The patient is a 28-year-old male, with no prior medical history of interest, who was ...

Introdução: A Síndrome de Adie-Homes é uma doença caracterizada pela presença pupila tônica associada à diminuição ou ausência dos reflexos tendíneos profundos. É considerada típica adultos jovens e apresenta etiologia comumente idiopática.A alteração no tamanho das pupilas queixas mais comuns. Apresentação do caso: Paciente sexo feminino, 28 anos, admitida em Hospital Geral Goiânia, apresentou...

PURPOSE To explore whether adaptation reduces the interocular visual latency differences and the induced Pulfrich effect caused by the anisocoria implicit in small-aperture monovision. METHODS Anisocoric vision was simulated in two adults by wearing in the non-dominant eye for 7 successive days, while awake, an opaque soft contact lens (CL) with a small, central, circular aperture. This was r...

BACKGROUND Convexity meningiomas are benign brain tumors that are amenable to complete surgical resection and are associated with a low complication rate. The aim of this study was to identify factors that result in acute postoperative neurological worsening after the removal of convexity meningiomas. METHODS Clinical evaluation and neuroradiological analysis of patients who underwent removal...

Widely varying pupillary abnormalities are in clinical practice often grouped under the heading of the Holmes-Adie syndrome. Adie (1932) described the complete form of the disorder as comprising the typical tonic pupil, with its characteristic delayed reaction to convergence and the loss of some of the tendon reflexes, whereas in the incomplete form he included those cases in which the reflexes...

PURPOSE To evaluate the long-term outcome of myopic photorefractive keratectomy (PRK). METHODS This prospective study included 31 patients (49 eyes) who underwent PRK between 1991 and 1993. A Summit UV200 excimer laser was used. Patients were divided into two groups--low myopia: preoperative < 6.00 diopters (D) (range: -1.50 to -5.75 D) (n = 19); and high myopia: preoperative > 6.00 D (range:...

BACKGROUND Herpes zoster ophthalmicus is defined as herpes zoster involvement of the ophthalmic division of the trigeminal nerve. Ocular involvement occurs in 20-70% of patients with herpes zoster ophthalmicus and may include blepharitis, keratoconjunctivitis, iritis, scleritis, and acute retinal necrosis. Orbital apex syndrome is a rare but severe ocular complication of herpes zoster ophthalmi...

BACKGROUND AND PURPOSE Mass effect of hematoma and the associated perihematomal edema are commonly responsible for neurological deterioration after intracerebral hemorrhage. Efficacy of surgical and medical therapy is limited. We studied the effect of early continuous hypertonic saline infusion on development of perihematomal edema after severe spontaneous supratentorial hemorrhage. METHODS P...

BACKGROUND Hospitals have a critically important role in the management of mass causality incidents (MCI), yet there is little information to assist emergency planners. A significantly limiting factor of a hospital's capability to treat those affected is its surgical capacity. We therefore intended to provide data about the duration and predictors of life saving operations. METHODS The data o...
