Primary malignant melanoma of the epiglottis: a rare presentation.

Primary malignant melanoma of the epiglottis is extremely rare. Until now, only 4 cases have been reported in the world literature. We describe a new case of epiglottic primary malignant melanoma in a 74-year-old man who presented with hoarseness and a foreign-body sensation. Clinical examination revealed the presence of a small, whitish, polypoid tumor on the laryngeal surface of the epiglottis; no other primary melanoma was detected. Wide excision of the lesion was performed, and microscopy revealed that it contained melanin-pigmented tumor cells in both the mucosa and submucosa. Immunostaining was positive for S-100 protein. The patient was treated with radiotherapy, and he remained well 1 year after the diagnosis with no evidence of recurrence.

Swallowed partial dentures.

Swallowed or inhaled partial dentures can present a diagnostic challenge. Three new cases are described, one of them near-fatal because of vascular erosion and haemorrhage. The published work points to the importance of good design and proper maintenance. The key to early recognition is awareness of the hazard by denture-wearers, carers and clinicians.

Urinary tract infection in surgical patients.

Urinary tract infection continues to be a major source of morbidity for surgical patients, and treating these infections continues to be a difficult problem in clinical surgical practice. The majority of these infections are due to urinary catheters. One strategy that has been advanced to prevent the morbidity associated with these infections is the use of silver-coated urinary catheters.

Actual time required for dynamic fluoroscopic intraoperative cholangiography.

OBJECTIVES: This study was undertaken to determine the actual amount of time a dynamic fluoroscopic intraoperative cholangiogram adds to a laparoscopic cholecystectomy. A secondary objective was to define the information gained from this procedure. METHODS: A consecutive case study of 52 patients undergoing laparoscopic cholecystectomy was used. Time was recorded from placement of a laparoscopic hemoclip across the cystic duct at its junction with the gallbladder until successful completion of the intraoperative cholangiogram. The mean, median, and range of times for these cases, as well as the results and false-negative rates, were determined. RESULTS: Cholangiography was successfully completed in 96% of patients. The mean time added to laparoscopic cholecystectomy by the addition of dynamic fluoroscopic intraoperative cholangiography was 4.3 minutes. The median time was 3.0 minutes. The times ranged from 2.0 minutes to 16.0 minutes. Choledocholithiasis was present in 15.4% of these patients. The false-positive rate was zero in this study. CONCLUSIONS: Dynamic fluoroscopic intraoperative cholangiogram was fast and efficient. The information gained was significant in that 15% of patients proceeded on to laparoscopic common bile duct exploration. We conclude that intraoperative cholangiography should be a routine addition to laparoscopic cholecystectomy.
