Bordetella pertussis causing otitis media: a case report.

OBJECTIVE/HYPOTHESIS: is an unusual cause of otitis media with effusion. We report a case in a neonate. STUDY DESIGN: Case report. METHODS: A case is presented. RESULTS: A 1-month-old infant girl was admitted because of respiratory distress and subsequently was found to have pertussis. On examination she was noted to have a middle ear effusion. Myringotomy was performed for culture. Culture confirmed. We were unable to find a previous report of otitis media. CONCLUSION: has been identified in the middle ear effusion of an infant with the pertussis syndrome.

Digital image archiving.

The digital camera has become a valuable component of the clinical practice for many otolaryngologist head and neck surgeons. Because several technical details distinguish digital cameras from their standard 35-mm counterparts, having some knowledge of these features is crucial for integrating digital imaging successfully into a practice. This chapter discusses these cameras and digital output, with an emphasis on their use in a medical practice. The author also explores current and future applications and gives a summary of limitations and benefits.

The effect of tension on patency of rat femoral artery anastomoses.

OBJECTIVE: To determine experimentally the role of tension in the failure of microarterial anastomoses. METHODS: Sixteen microarterial anastomoses were performed in femoral arteries from adult Sprague-Dawley male rats after resecting 0, 1, 2, or 3 mm. The percentage of vessel excised was calculated. The vessel was then examined in approximately 1 week for patency. Next, 5 femoral arteries were excised and length-tension curves generated. RESULTS: All vessels were patent in which less than 20% of the length was resected. Clinically, only vessels under extreme tension failed. Length-tension curves suggested 2 zones of vessel extensibility with a breakpoint between them. Extension of the vessel beyond this breakpoint required extreme tension. CONCLUSIONS: Moderate tension at a microarterial anastomosis does not lead to anastomotic failure. Failure occurs after the elastic reserve of the vessel is exceeded.
