An 85-year-old woman was found comatose. Her right pupil was 2 mm and reactive while the left pupil was 6.5 mm and nonreactive (figure, A). Oculocephalic and corneal reflexes were absent, the cough reflex was preserved, and there was spontaneous bilateral decerebrate posturing. Traditional teaching indicates that midbrain lesions cause fixed, midposition pupils while pontine lesions cause pinpo...

Three weeks after severe traumatic brain injury (pedestrian hit by a car) and correction of initial intracranial hypertension, a brain MRI is performed in a 22-yearold woman, who remains in a comatose state (Glasgow Coma Scale at 4, with withdrawal to painful stimuli; abolition of photomotor reflex; persistence of corneal and cough reflexes). Fluid-attenuated inversion recovery and T2*-weighted...

After a careful analysis the most generous critic will find difficulty in pointing to any merit in this book. The reader is unavoidably driven to the conclusion that the personal experience of the author in any but the most elementary forms of anaesthesia_ i9 extremely limited. The casual dismissal in four lines of the technique of administration of an endotracheal anaesthetic does not suggest ...

the term reflex epilepsy in reserved for a small subgroup o seizures that occur regularly in response to specific stimuli. our patient is a 20- year old male, who had pleasure, euphoria, loss of conciousness and generalized tonic- clonic convulstion when he watched tv since ten years. during puberty the patient that self-induced reflex epilepsy with photic stimulation, when watching tv or looki...

profound bradycardia during eye surgery is a potentially serious event. in clinical practice oculo-cardiac reflex (ocr) is most often encountered during squint surgery. the objective of this study was to assess the occurrence of ocr and prove the effect of ketamine as an induction drug and anticholinergic premedication (atropine) to prevent ocr. this study comprised 90 patients (aged 4-10 years...

In the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. Acute corneal pain was induced by the local application of hypertonic saline (5 M NaCl) on the corneal surface, and the number of eye wipes was then counted for 30 s. Subcutaneous (s...

Both cytotoxic and invasive strains of Pseudomonas aeruginosa can damage corneal epithelial cells in vitro, but neither can infect healthy corneas in vivo. We tested the hypothesis that whole human tear fluid can protect corneal epithelia against P. aeruginosa virulence mechanisms. Cultured corneal epithelial cells were inoculated with 10(6) CFU of one of 10 strains of P. aeruginosa (five cytot...

BACKGROUND Anoxic-ischemic coma has a poor outcome with a high rate of mortality and morbidity. Therefore, clinical predictors of prognosis are needed for therapeutic decision-making. PATIENTS AND METHODS Prospective analysis of 46 patients, 31 male, age range 19-85 years, with anoxic-ischemic coma following cardiac arrest. All the patients included in our study remained comatose with a Glasg...
