Transcranial ultrasonography to detect intracranial pathology: A systematic review and meta-analysis.

Background And Purpose: Transcranial ultrasonography (TCU) can be a useful diagnostic tool in evaluating intracranial pathology in patients with limited or delayed access to routine neuroimaging in critical care or austere settings. We reviewed available literature investigating the diagnostic utility of TCU for detecting pediatric and adult patient's intracranial pathology in patients with intact skulls and reported diagnostic accuracy measures.

Methods: We performed a systematic review of PubMed , Cochrane Library, Embase , Scopus , Web of Science™, and Cumulative Index to Nursing and Allied Health Literature databases to identify articles evaluating ultrasound-based detection of intracranial pathology in comparison to routine imaging using broad Medical Subject Heading sets.

Brain topography on adult ultrasound images: Techniques, interpretation, and image library.

Background And Purpose: Many studies have explored the possibility of using cranial ultrasound for discerning intracranial pathologies like tumors, hemorrhagic stroke, or subdural hemorrhage in clinical scenarios where computer tomography may not be accessible or feasible. The visualization of intracranial anatomy on B-mode ultrasound is challenging due to the presence of the skull that limits insonation to a few segments on the temporal bone that are thin enough to allow transcranial transmission of sound. Several artifacts are produced by hyperechoic signals inherent in brain and skull anatomy when images are created using temporal windows.

Repeat prescribing safety survey.

INTRODUCTION Repeat prescribing is an accepted part of general practice activities in New Zealand and in many developed countries. However, there has been little research on how this service is used in New Zealand, or on clinicians' attitudes towards it. AIM To discover the opinions of vocationally registered general practitioners (GPs) and general practice registrars regarding repeat prescribing, availability of practice policy and mechanisms for issuing such prescriptions.

Caption-based topical descriptors for microscopic images as published in academic papers.

Background: Visual findings summarized in the figures and tables of academic papers are invaluable sources for biomedical researchers. Captions associated with the visual findings are often neglected while retrieving biomedical images in published academic papers.

Objectives: This study is to assess caption-based topical descriptors for microscopic images of breast neoplasms, as published in academic papers retrieved through the PubMed Central database.
