background the purpose of this study was to evaluate the characteristics, management, and outcomes of disc battery ingestion in children. methods we reviewed the medical records of children admitted to mofid children's hospital due to disc battery ingestion from january 2006 to january 2010. clear history, clinical symptoms and results of imaging studies revealed diagnosis of disc battery inges...
Disc edge veins of Kraupa are anomalies of the retinal venous system in which blood flows from the retina through a single venous trunk at or near the edge of the disc instead of at its centre. We report two examples of patients with these anomalies and illustrate the appearance of the anomalies with fundus photographs and a fluorescein angiogram. In one patient the retinal vein exited the eye ...
Rocks are less resistant to tension than compression or shear. Tension cracks commonly initiate shear failure. The mechanical behavior of layered rocks under has been studied extensively, whereas the tensile still remains uncertain. In this paper, we study effect layer orientation on strength and failure patterns direct indirect through experimental numerical testing (RFPA2D: software Rock Fail...
Tensile strength is an important control parameter for the design and stability analysis in rock engineering. In order to reveal influence of elastic modulus on tensile test results, Brazilian splitting tests were carried out specimens with different strengths, such as mudstone, white sandstone, green red marble. Longitudinal transverse strains monitored analyze maximum contact angle peak load ...
even though intervertebral disc degeneration can be found in the natural course of alkaptonuria, detection of the disease by black disc color change in a patient without any other presentation of alkaptonuria is an exceptionally rare condition. we have reported a very rare case of alkaptonuria presented with low back pain and steppage gait in a 51-year-old male with a complaint of chronic low-b...
OBJECTIVES To assess (a) the trend of MEDLINE citation of pediatrics articles associated with Brazilian institutions from 1990 through 2004; (b) the number of Brazilian pediatrics articles published in journals with the highest impact factor; and (c) the regional distribution of institutions. METHODS PubMed search limited to ages 0 to 18 years, English language, MEDLINE and humans subsets, Br...
Through the Life Cycle of Intraoperative Transesophageal Echocardiography (ETTI/SBA) the Brazilian Society of Anesthesiology, together with the Department of Cardiovascular Image of the Brazilian Society of Cardiology (DIC/SBC), createded a task force to standardize the use of intraoperative transesophageal echocardiography by Brazilian anesthesiologists and echocardiographers based on scientif...
STUDY DESIGN An in vitro biomechanical study using aged human and adolescent porcine discs. OBJECTIVES To find the leakage pathway and effect of needle gauge on the degree of disc injury post anular puncture. SUMMARY OF BACKGROUND DATA Spinal needles are widely used for minimal invasive disc surgeries and disc degeneration/regeneration research. Applications of anular puncture require diffe...
