background: uterine arteriovenous malformation is a rare but potential life-threatening source of bleeding. a high index of suspicion and accurate diagnosis of the condition in a timely manor are essential because instrumentation that is often used for other sources of uterine bleeding can be lead to massive hemorrhage. case: we describe here a case of uterine arteriovenous malformation. a 32-y...

sulfur mustard (sm) has been used as a chemical warfare agent, in the world war i and more recently during iraq-iran war in early 1980s’. its biological poisoning effect could be local or systemic and its effect depends on environmental conditions, exposed organs, and the extent and duration of exposure. it is considered as a strong alkylating agent with known mutagenic, carcinogenic effects; a...

Holt-Oram syndrome (HOS) is a disorder characterized by skeletal abnormalities in the upper limbs accompanied by cardiovascular defects. The diagnosis of HOS is based on these abnormalities and defects, both in the individual or in the parents, and is indicative of congenital transmission. All those affected by this syndrome have upper limb skeletal abnormalities, which preferentially affect th...

Congenital lobar emphysema (CLE) is a rare developmental malformation that presents as neonatal respiratory distress and can be successfully managed with prompt intervention. Hyperinflation of the affected lobe mediastinal shift characteristic radiological finding. However, etiology mostly remains unknown. Here, we report case CLE microscopically revealed bronchial cartilaginous hypoplasia an u...

Dural sinus malformation is an extremely rare congenital cerebrovascular malformation. We report serial antenatal sonographic findings in two patients with dural sinus malformation. Sonography can reveal dural sinus malformation at 24 weeks' gestation. Correct and early diagnosis may help determine the appropriate place, timing, and mode of delivery, which may result in a better therapeutic cou...

backgroundsitting on inappropriate benches, as well as the poor posture (body position) during the years of growth, can lead to spinal disorders, fatigue and discomfort in students. this study aimed to investigate the relationship between features of desks and chairs and prevalence of some musculoskeletal disorders in primary school students in abadan.materials and methodsthis cross-sectional s...

background prediction of skeletal growth is necessary for growth modification and surgical orthodontic treatments and is usually done by assessing skeletal maturity indicators in hand-wrist radiographs. the use of growth stages of cervical vertebrae in lateral cephalograms has been suggested to avoid overexposure. objectives this study seeks to assess the degree of agreement between hand-wrist ...

skeletal muscle is a highly differentiated tissue with very specific functions which has low potential of regeneration. skeletal muscle injuries especially in athletes almost have lead to muscular dysfunctions and healing may be prolonged for several years. therefore, working on skeletal muscle differentiation remained an importance in biomedical researches. adipose derived stem cells (adscs) a...
