Pupil-sparing cranial nerve III palsy after intranasal cocaine treatment for cluster headache.

This case report discusses a cranial nerve III palsy in a 47-year-old, type II diabetic man that originally presented with a cluster headache that was treated with 100% oxygen by nasal cannula, 975 mg Tylenol, and 100 mg of Imitrex without any symptom relief. He then received a sphenopalatine fossa block using 1 ampule of 4% cocaine. Three days after medicinal, intranasal cocaine for treatment of a cluster headache, the patient presented with a cranial nerve III palsy with spontaneous resolution in 4 months without any intervention.

Public accessibility of biomedical articles from PubMed Central reduces journal readership--retrospective cohort analysis.

Does PubMed Central--a government-run digital archive of biomedical articles--compete with scientific society journals? A longitudinal, retrospective cohort analysis of 13,223 articles (5999 treatment, 7224 control) published in 14 society-run biomedical research journals in nutrition, experimental biology, physiology, and radiology between February 2008 and January 2011 reveals a 21.4% reduction in full-text hypertext markup language (HTML) article downloads and a 13.8% reduction in portable document format (PDF) article downloads from the journals' websites when U.

The effect of public deposit of scientific articles on readership.

A longitudinal cohort analysis of 3,499 articles published in 12 physiology journals reveals a 14% reduction in full text article downloads when they are made publicly available from the PubMed Central archive. The loss of article readership from the journal website may weaken the ability of the publisher to build communities of interest around the research article, impede the communication of news and events with society members and reduce the perceived value of the journal to institutional subscribers.

The persistence of error: a study of retracted articles on the Internet and in personal libraries.

Objective: To determine the accessibility of retracted articles residing on non-publisher websites and in personal libraries.

Methods: Searches were performed to locate Internet copies of 1,779 retracted articles identified in MEDLINE, published between 1973 and 2010, excluding the publishers' website. Found copies were classified by article version and location.

How Shakespeare tempests the brain: neuroimaging insights.

Shakespeare made extensive use of the functional shift (FS), a rhetorical device involving a change in the grammatical status of words, e.g., using nouns as verbs.

The impact of free access to the scientific literature: a review of recent research.

Objectives: The paper reviews recent studies that evaluate the impact of free access (open access) on the behavior of scientists as authors, readers, and citers in developed and developing nations. It also examines the extent to which the biomedical literature is used by the general public.

Method: The paper is a critical review of the literature, with systematic description of key studies.

Open access, readership, citations: a randomized controlled trial of scientific journal publishing.

Does free access to journal articles result in greater diffusion of scientific knowledge? Using a randomized controlled trial of open access publishing, involving 36 participating journals in the sciences, social sciences, and humanities, we report on the effects of free access on article downloads and citations. Articles placed in the open access condition (n=712) received significantly more downloads and reached a broader audience within the first year, yet were cited no more frequently, nor earlier, than subscription-access control articles (n=2533) within 3 yr. These results may be explained by social stratification, a process that concentrates scientific authors at a small number of elite research universities with excellent access to the scientific literature.

Open access publishing, article downloads, and citations: randomised controlled trial.

Objective: To measure the effect of free access to the scientific literature on article downloads and citations.

Design: Randomised controlled trial.

Setting: 11 journals published by the American Physiological Society.

Event-related potential characterisation of the Shakespearean functional shift in narrative sentence structure.

Neurolinguistic studies have scrutinised the physiological consequences of disruptions in the flow of language comprehension produced by violations of meaning, syntax, or both. Some 400 years ago, Shakespeare already crafted verses in which the functional status of words was changed, as in "to lip a wanton in a secure couch". Here, we tested the effect of word class conversion as used by Shakespeare--the functional shift--on event-related brain potential waves traditionally reported in neurophysiolinguistics: the left anterior negativity (LAN), the N400, and the P600.

Preventing disability from occupational musculoskeletal injuries in an urban, acute and tertiary care hospital: results from a prevention and early active return-to-work safely program.

Objective: Healthcare workers are at high risk for musculoskeletal injuries. A program was developed to decrease the incidence of musculoskeletal injuries and the duration of associated time loss.

Methods: A program combining primary prevention and on-site early intervention was implemented at a large, urban hospital.
