purpose: to determine the prevalence of various types of conjunctival lesions, at a tertiary ophthalmic center in fars province, south of iran. methods: histopathologic slides and medical records of conjunctival lesions submitted to the pathology department of khalili hospital, shiraz, iran was reviewed from april, 2009 to july, 2013. the histopathologic diagnoses were categorized into benign, ...

the possibility that infectious agents may trigger a cascade of reactions leading to inflammation, atherogenesis and vascular thrombotic events has recently been raised. chlamydia pneumoniae is an infectious agent that has received the most attention with respect to coronary artery disease (cad). to determine the relationship between c. pneumoniae and cad, a case control study was conducted on ...

skin lesions were found in two 3–4-year-old holstein cows in a dairy farm in shiraz. lesions were distributed mostly around the neck, forelimbs, hindlimbs, and bilateral of midline portion and varied from nodule-like structure to patch with extensive accumulation of crust. skin scraping samples were taken from each animal and direct smears were prepared, stained with giemsa and observed under a...

paragangliomas in the head and neck are found typically in the region of the carotid body, jugular body, and along the 9th and 10th cranial nerves. they can occur in multicenteric forms, but generally, laryngeal paragangliomas are not found in these patients. only two cases of laryngeal paraganglioma have been reported with a synchronous lesion elsewhere. we report an additional case of a 34-ye...

Lesions of anatomical brain networks result in functional disturbances of brain systems and behavior which depend sensitively, often unpredictably, on the lesion site. The availability of whole-brain maps of structural connections within the human cerebrum and our increased understanding of the physiology and large-scale dynamics of cortical networks allow us to investigate the functional conse...

The present study used 2 different discrimination tasks designed to isolate distinct components of visuospatial learning: structural learning and geometric learning. Structural learning refers to the ability to learn the precise combination of stimulus identity with stimulus location. Rats with anterior thalamic lesions and fornix lesions were unimpaired on a configural learning task in which t...

Sir: Psychiatric disorders can co-occur with seizure disorders but can also be secondary to structural lesions in the brain. These lesions are directly responsible for both the epileptic focus and psychiatric symptoms. Psychoses associated with seizures are among those of major concern to both psychiatrists and neurologists. Psychosis and seizure disorders associated with structural lesions rep...

AIM To provide first evidence of construct validity of a semi-quantitative scale for brain structural MRI (sqMRI scale) in children with unilateral cerebral palsy (UCP) secondary to periventricular white matter (PWM) lesions, by examining the relationship with hand sensorimotor function and whole brain structural connectivity. METHODS Cross-sectional study of 50 children with UCP due to PWM l...
