Input: Consider Input: Abstract: Impairment of the mucosal microcirculation may contribute to ethanol-induced gastric mucosal damage. In this report, we describe diffuse and severe ultrastructural damage to the capillaries of the gastric glandular mucosa of the rat that occurred within 1 min after intragastric instillation of 100% ethanol. There was a gradient of damage in that endothelial cell structure was most severely disrupted in profiles of capillaries located close to the luminal surface but some morphologic evidence of damage was evident in the wall of capillary profiles to a mean depth of 256 micron. Capillary structure was generally normal in the deeper regions of the mucosa. Pretreatment with intragastric cysteamine, 30 mg/100 g, or intragastric prostaglandin F2 beta, 0.5 mg/100 g, significantly reduced the depth in the mucosa to which damage to capillaries extended. Pretreatment with intragastric prostaglandin F2 beta, 0.2 mg/100 g, afforded no significant protection. We conclude that a 1-min exposure to 100% ethanol induces striking damage to the microcirculation of glandular mucosa of the rat stomach with severe damage to capillary profiles near the lumen and sparing of capillary profiles near the muscularis mucosa, and pretreatment with the sulfhydryl agent, cysteamine, or with a large dose of prostaglandin F2 beta reduces the extent of but does not abolish ethanol-induced damage to gastric mucosal capillaries.

Input: Consider Input: Abstract: Magnetic resonance imaging (MRI) and computed tomography (CT) were compared in four children who had evidence of intracranial injury caused by shaking. All children had intracranial bleeding, neurologic impairment, and history or physical examination findings suggestive of child abuse. Three had bilateral retinal hemorrhages, and three had visual impairment. MRI revealed bilateral subdural hematomas in all four children, but CT showed this in only one. Skull fractures in one patient were visualized by CT alone. MRI alone demonstrated posterior fossa bleeding in one patient and intraparenchymal bleeding in another; an additional patient in whom CT showed relatively diffuse atrophy also had defined areas of focal atrophy apparent on MRI. Subarachnoid hemorrhages were equally well detected using CT or MRI. Overall, MRI was superior to CT for detection of intracranial injury caused by shaking, and may help to document milder instances of this form of child abuse.

Input: Consider Input: Abstract: In an earlier report, the authors demonstrated a trend toward progressive hyperopia in radial keratotomy (RK) patients examined between one and three to four years postoperatively. In those 109 cases, the surgeries were performed using a metal-blade instrument. In the following study, the metal-blade series was updated to a total of 225 procedures, and a more recent series of 300 procedures performed on 228 patients was examined in which a diamond-knife cutting instrument was used. Patients had uncorrected visual acuity determination, cycloplegic refractions with best corrected visual acuity measurements and keratometry measurements. The authors demonstrated a hyperopic shift in the distribution of postoperative spherical equivalent (SE) values across time such that higher proportions of cases in both metal-blade and diamond-knife series were at least 1.0 diopter (D) away from emmetropia at 24 and 48 months than was the case at 12 months after surgery. Regression analysis determined that none of the preoperative or surgical variables known to affect refractive outcome of RK (alone or in combination) could account for the changes in refraction seen during the course of postoperative time. In general, changes in keratometry paralleled refractive changes, but were somewhat smaller in magnitude.
