mandibular defects may result from many conditions such as trauma, inflammatory diseases and tumors. there are rare cases reported in the literature that have demonstrated spontaneous bone regeneration after resection of the mandible. several factors such as age, preservation of the periosteum and genetics seem to influence spontaneous bone regeneration capacity in individuals. evaluation of th...

background: ascitic fluid infection is presumptively diagnosed when the fluid polymorph nuclear (pmn) concentration equals or exceeds 250 cells /mic,l. the leukocyte esterase (le) test has been shown to be a good predictor of the presence of pmns in urine and other body fluids. this study examines of value of multistix 8sg dipstick test for rapid diagnosis of infected ascitic fluid. materials a...

conclusions a lumbar hernia may, on rare occasions, become incarcerated or strangulated, with the consequent complication of mechanical bowel obstruction. we suggest that a patient with a flank mass should always raise suspicions of a lumbar hernia. case presentation a 76-year-old woman who had been diagnosed with a femoral intertrochanteric fracture was sent to our department. physical examina...

spontaneous pneumothorax can be either primary due to the rupture of subpleural bleb or secondary due to underlying lung disease, usually bullous emphysema. 1 relatively little is known about the causative factors of spontaneous pneumothorax in arab countries. 1 this is the first study and the primary step towards understanding the risk factors and causes of spontaneous pneumothorax in syria. s...

background noise most frequently affects hearing system, as it may typically cause a bilateral, progressive sensorineural hearing loss at high frequencies. objectives this study was designed to compare three different methods to evaluate noise-induced hearing loss (conventional audiometry, high-frequency audiometry, and distortion product otoacoustic emission). material and methods this was a c...

it has been recognized that acute and chronic stress has an impact on the immune system. acute stress may have a stimulating effect on the immune system, while in the case of chronic stress specially depression, the immune system could be down-regulated. however, an association between depression and a higher number of circulating white blood cells with increased activity has been reported. ele...

background:   objective: in this study we performed linkage analysis on a large x linked rsa pedigree to find a novel susceptibility locus for rsa.   materials and methods: a linkage scan using 11 microsatellites was performed in 27 members of a large pedigree of hereditary x-linked rsa. two point parametric linkage was performed using superlink v 1.6 program. results: evidence of linkage was o...

background: human leukocyte antigen-e (hla-e)is a non-classical major histocompatibility complex (mhc) class i antigens which expressed on extra villous cytotrophoblast, which interacts with nkg2a, is an inhibitory receptor on natural killer (nk) cells and leading to down regulation of immune response in the maternal-fetal interface and provides maternal immune tolerance of the fetus. objective...
