abstract objective tumors of the central nervous system constitute the largest group of solid neoplasms in children and are second only to leukemia in their overall frequency during childhood. the main purpose of the present study is to determine the incidence, age, sex, location and histological diagnosis of cns tumors in children, less than 15 years of age, in the mofid children's hospital, i...

intracranial hemangiopericytomas (hpc) are rare vascular tumors. they account for 0.4% of primary central nervous system tumors. hpc is more commonly located supratentorially and tends to occur in a younger age group, with average age at presentation of 38–42 years. the tumor was found throughout the entire cns, usually superficially and closely related to the meninges. moreover, they have a st...

INTRODUCTION Shoulder-hand syndrome is a relatively rare clinical entity classified as a complex regional pain syndrome type 1 and consisting essentially of a painful 'frozen shoulder' with disability, swelling, vasomotor or dystrophic changes in the homolateral hand. The pathophysiology is not completely clear but a predominant 'sympathetic' factor affecting the neural and vascular supply to t...

For pre-surgical planning we present quantitative comparison of the location of the hand motor functional area determined by right hand finger tapping BOLD fMRI, resting state BOLD fMRI, and anatomically using high resolution T1 weighted images. Data were obtained on 10 healthy subjects and 25 patients with left sided brain tumors. Our results show that there are important differences in the lo...

Lipomas are the most common benign mesenchymal tumors. They are located either subcutaneously or under the investing fascia in intramuscular or intermuscular regions. The reported frequency of intramuscular lipomas among all benign adipocytic tumors is 1.0%-5.0% and for intermuscular lipomas is 0.3%-1.9%. The frequency of these lesions is the same in all age groups, but in adults deep seated-li...

Introduction: Photodynamic therapy is a noninvasive therapeutic method for tumors with a maximum depth of 5 mm. On the other hand, most photosensitizers are also susceptible to ultrasound waves (the basis of sonodynamic therapy). Therefore, it is expected that a combination of the two therapeutic methods will increase effectiveness of photodynamic therapies for lower doses of sensitizer and cur...

Background and Objectives: Hand hygiene (HH) is crucial for preventing of infectious complications in health care settings. Informing healthcare workers on the recommended hand washing method can promote this practice in the clinical staff. This study aimed to evaluate the impact of training the WHO-recommended five-moment hand washing method in promoting hand hygiene in a health care setting. ...

Serially obtained urinary polyamine levels were determined for 192 patients during a specified time period. The number of patient urine samples totaled 938. The patients had tumors of either the breast, stomach, prostate, or female genital tract, or metastatic carcinomas of unknown origin. Tumor activity and tumor volume, along with other clinical information, were also recorded during the time...
