Clinical TrialDifferences in toxicity across gender in patients treated with chemoradiation for rectal cancer.
The primary objective was to prospectively investigate the efficacy and toxicity of bolus 5-fluorouracil (5-FU) chemotherapy compared with the infusional 5-FU in combination with preoperative radiation in patients with locally advanced rectal cancer. Furthermore, in light of previous reports, toxicity profiles between men and women were also compared. ⋯ In locally advanced rectal cancer, preoperative infusional chemotherapy combined with radiation was found to be less toxic than bolus chemotherapy and radiotherapy. Both regimens produced more toxic effects in women compared with men.

Case ReportsTwo cases of methanol poisoning: CT and MRI features.
Methanol poisoning in Australia is now very rare as methanol has been removed from methylated spirits. In acute intoxication methanol may result in a wide range of damage to the central nervous system. Few cases have been imaged with MRI. We present two cases and their striking neuroimaging findings with a discussion of the published work on methanol poisoning.

The management of a blocked long-term central venous catheter has traditionally been removal and re-siting, even when device failure is not associated with venous thrombosis or sepsis. It is not possible to 'railroad' a split dual-lumen central venous catheter down a long tortuous s.c. tunnel. Our exchange technique was designed to salvage the tunnel and venous access site in a long-term catheter that has had uncomplicated primary device failure. ⋯ The new catheter is then introduced in the conventional manner through the two peel-away sheaths, which are then removed. The key advantage of the technique is that it preserves one of the few central venous access sites available. This article describes exchange of an internal jugular catheter, but the same technique is applicable to subclavian catheters.

Case ReportsIntercostal artery aneurysms complicating thoracic aortic coarctation: diagnosis with magnetic resonance angiography.
The case report of a 46-year-old woman diagnosed with complete aortic coarctation and multiple intercostal artery aneurysms using 'ultrafast time-resolved' multiphase contrast-enhanced magnetic resonance angiography and conventional single-phase, high-resolution breath-hold contrast-enhanced magnetic resonance angiogram techniques is presented. A review of intercoastal artery aneurysms occurring in conjunction with aortic coarctation and the various contrast-enhanced magnetic resonance angiography techniques currently available is provided.
