Verrucous carcinoma is a rare squamous cell variant that may arise in the bladder. We present a case of verrucous carcinoma of the bladder with radiologic-pathologic correlations that demonstrate the characteristic frond-like growth pattern. Verrucous carcinoma is an invasive but not a metastizing lesion, and therefore recognizing this lesion may have prognostic and therapeutic implications.

Giant air cyst of the sigmoid complicating diverticulitis: report of a case.

A giant gas cyst of the sigmoid is reported, and the relevant medical literature is discussed. The vast majority of these lesions are pseudocysts and are a complication of diverticulitis that has not been emphasized in previous reports. The diagnosis should be able to be established by various roentgenographic procedures.

Appearance of renal infarction on computed tomography.

We have recently seen three cases of renal infarction secondary to occlusion of renal arteries. Two of these cases had similar clinical presentations and were not diagnosed until computed tomographic (CT) scans were performed (1). The third case was a serendipitous finding. The abnormal findings on CT led to angiography, which confirmed the CT findings in all cases. The CT appearance in those cases was diagnostic, whereas the changes on urography were minimal, if any. We believe that angiography and surgery may be obviated when cases exhibit these characteristic findings on CT.

An aid to blind nasal intubation.

Blind nasal intubation remains an important technique in the management of the difficult airway. Many aids to this technique have been described, but unfortunately, these often require additional expense, training, and equipment. Methods that involve listening at the end of the endotracheal tube and observing moisture condensation in the tube are relatively insensitive and may expose the operator to the patient's bodily fluids. Our aim was to devise an aid to blind nasal intubation that was effective, inexpensive, simple to learn, and easy to assemble. It is essential that breath sounds can be monitored through the endotracheal tube, as it is felt that this helps to minimize retropharyngeal perforation caused by the tube abutting the posterior pharyngeal wall. We describe the use of an endotracheal tube stethoscope in conjunction with either 'inline' or 'sidestream' capnometry and present a case of successful nasotracheal intubation using this device. The total cost of this aid is less than $10 Australian.
