Introduction: Cerebral venous-sinus thrombosis (CVST) is a life threatening condition that needs rapid diagnosis and treatment. It appears comparatively more common in Middle East and South Asia. Objectives: To determine the demographic, clinical patterns, etiologies and prognostic factors of CVST in the North East of Iran. Materials and Methods: All adult patients admitted with a documented di...

BACKGROUND Diagnostic reasoning is a key competence of physicians. We explored the effects of knowledge, practice and additional clinical information on strategy, redundancy and accuracy of diagnosing a peripheral neurological defect in the hand based on sensory examination. METHOD Using an interactive computer simulation that includes 21 unique cases with seven sensory loss patterns and eith...

In a study of the time course and nature of the sensory loss after cryosurgery the forearms of nine normal subjects were treated with liquid nitrogen using freeze times currently employed in clinical practice in Britain. Ability to appreciate touch, pinprick, and cold in the treated areas was tested at regular intervals and biopsy samples taken to investigate the pathogenesis. Appreciation of a...

The aim in this review article is to document research findings that have shown paradoxical effects of nervous system changes, whereby direct or indirect neural damage may result in facilitation of behavioural functions. Such findings have often been ignored or undervalued in the brainbehaviour research literature. A further aim is to consider possible mechanisms and theoretical insights relate...

This study aimed to determine the aerosolization behavior of a nanodispersion of budesonide, prepared using microfluidic reactors. The size and morphology of budesonide nanoparticles were characterized by photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM). Processing/formulation parameters for formation of the nanoparticles were studied to determine their effects o...

the present study was carried out to characterize the cervical mucus (cm) collected when inseminating holstein cows and to relate the secretion pattern with pregnancy. the mucus was collected from mid-cervix of 64 cows with spontaneus estrus (se) and induced estrus (ie). the quantity, pattern and consistency of the mucus, ph, arborization patterns and the sperm motility were observed. the level...

PURPOSE The prevalence of infective endocarditis (IE) among children with Staphylococcus aureus bacteremia (SAB) is unknown. The objective of this study was to determine prospectively the prevalence of IE among pediatric patients with SAB in a large tertiary care center. METHODS Between July 1998 and June 2001, all children who developed SAB whose parent/guardian signed informed consent under...
