Rigidity of the thorax in ankylosing spondylitis was first recognized as long ago as 1695, when Bernard Connor described a skeleton showing the characteristic rigidity of the thoracic cage and lumbar spine and concluded that respiration must have been greatly restricted during the life of the unfortunate sufferer. This astute observation remained the only one of its kind until Hilton Fagge (187...

We are now about half way through our term of office (unless we are prematurely fired for terminal misbehaviour); here we review where we are, and where we are going, and have the first instalment of the showcase of some of our best articles from last year. We have maintained our second position with an improved impact factor (6.84) over 2011, we continue to attract very high quality manuscript...

a 50-year-old male underwent a check-up for an insurance company. chest x-ray revealed a large ball-like lesion in the posterior mediastinum. the finding was confirmed by computed tomography (ct) scan (figure 1). the patient was referred to our center, where he had a successful mass removal surgery (figure 2). pathology identified the mass as neurinoma.

background: chest trauma is responsible for 50% of deaths due to trauma. this kind of death usually occurs immediately after the trauma has occurred. objectives: the aim of this study was to evaluate the various aspects of chest trauma in patients admitted to two main trauma centers located in the isfahan province, iran. conclusions: since hemothorax is the main complication of blunt chest trau...

conclusions performing the routine chest ct in high-energy blunt trauma patients (with a mean injury severity of 9), although leading to the diagnosis of some occult injuries, has no impact on the outcome and does not decrease the in-hospital stay and icu admission time. it seems that performing the routine chest ct in these patients may lead to overtreatment of nonsignificant injuries. the dec...

The position and orientation of the thorax and head of flying blowflies (Calliphora vicina) were measured using small sensor coils mounted on the thorax and head. During flight, roll movements of the thorax are compensated by counter rolls of the head relative to the thorax. The yaw turns of the thorax (thorax saccades) are accompanied by faster saccades of the head, starting later and finishin...

In the follow-up study of adolescents residual volume (RV), vital capacity (VC), closing volume (CV), thorax height and thorax width were measured at six month intervals over a six year period; 149 girls and 477 boys, whose ages ranged between 11.5 and 18.5 yr during the follow-up, were investigated. In healthy subjects and in those with respiratory symptoms the rates of change of thoracic dime...

background: in vivo dosimetry is a method for estimation of overall error in the delivered dose to the patients at the end of radiotherapy process. in this research, two methods for target dose calculation were evaluated on midline and central axis of photon beams in in vivo dosimetry of thorax fields. materials and methods: entrance and exit doses for anterior and lateral fields of thorax were...
