Management of esophageal injuries.

A multiinstitutional study of 39 esophageal injuries treated between 1982 and 1988 and a comprehensive review of the literature revealed an unacceptably high mortality rate of more than 20%. Results of the current study indicated that prompt diagnosis and aggressive surgical management of esophageal injuries could improve the outcome and lower the associated mortality. The clinical experience and literature review allowed us to elaborate caveats and principles that, if adhered to, should improve the outcome in esophageal injuries.

Cerebral lymphoma in childhood: a diagnostic dilemma.

A diffuse B cell lymphoma was recognized at autopsy in an otherwise healthy 3 1/2-year-old girl with a three-month history of recurrent seizures. This lymphoma, treated only by debulking, was found at autopsy to have originated in the right cerebral hemisphere and to have metastasized throughout the brain, the leptomeninges around the brain stem and cerebellum, and the ventricular system. Unusual features in this lymphoma included tumoral calcifications associated with necrosis, tumoral cystic changes, polyclonal tumor cells, and meningeal metastases.

Eye fixations predict reading comprehension: the relationships between reading skill, reading speed, and visual inspection.

This experiment addressed the question of whether reading comprehension and speed could be predicted by eye fixations. From a sample of university students who completed tests of reading comprehension and vocabulary, we selected a group of highly skilled readers and a group of less skilled readers. These two groups then read sentences as their eye movements were monitored, with fixation locations and durations recorded. A discriminant function analysis showed that fixation duration was a successful predictor of reading comprehension, but that the number of fixations, regressive fixations, reading speed, and vocabulary were not reliable predictors. A multiple regression analysis revealed that reading speed was predicted by the number of fixations, the average fixation duration, and the duration of the final fixation upon the sentence, but there was no relationship with reading ability. Highly skilled readers are those who can extract information efficiently, but are not necessarily those who have fast overall reading rates.
