Migration of thoracic epidural radio-opaque catheters was evaluated in 25 patients scheduled for thoracic surgery in the supine position (n = 5) or in the lateral position with lateral extension of the thoracic spine (n = 20). Chest radiography was performed daily for 3 days after operation. Eighty-nine per cent of catheter tips were visualised in the epidural space. The catheter tip position w...

Complete opacification of a hemithorax on chest X-ray is termed opaque hemithorax (OH) and is a common finding in emergency room patients. Attending physicians encountering an OH should be able to make an immediate decision regarding the most appropriate approach. The differential diagnosis of an OH is primarily based on the volume of the affected hemithorax, as determined by the position of th...

Considerable controversy exists concerning the relationship between the tissue spaces of the central nervous system and meninges, and those of the remainder of the body. It has been suggested that some materials may reach the central nervous system by routes other than through the hematoencephalic barrier. One suggested pathway is the tissue spaces of peripheral nerves. Other work in this labor...

The integration of therapeutic and imaging functions in a nanoscale structure is gaining increasing attention to monitor drug and gene delivery in a non-invasive real-time manner. Here we introduce radioopaque nanoemulsions incorporating paclitaxel and Bcl-2 small interfering RNA (siRNA) for synergistic anti-cancer theranostics. Water-insoluble paclitaxel is readily dissolved in iodinated poppy...

The use of roentgenograms of post mortem fixed brain tissue slices for demonstrating the extent, density, and distribution of radio-opaque material is not new. As early as 1909 Frankel (3) demonstrated the distribution of cerebral calcification by means of roentgen films of tissue slices. Although he apparently presented these films while reading his paper, no reproductions were ever printed, a...

revascularization are needed. We also agree with Conti’s opinion that, unless ischemia is present, collaterals do not appear angiographically; if the collateral provides excellent blood flow to ischemic myocardium, the collaterals will remain (2). Werner et al. (3) reported that even collaterals that appear well developed on angiography are not able to fully replace anterograde blood flow; ther...

OBJECTIVE The aim of this study was to assess the risk factors and preventive measures for gossypibomas and their medico-legal implications in forensic medicine in the Turkish legal system. MATERIAL AND METHODS This study involved a retrospective analysis of the records of 39 patients with gossypiboma. Records were available from the Istanbul Forensic Medicine Institution and were surveyed fo...
