Bleeding, is one of the most common postoperative complications after palatoplasty in patients with cleft palate. The purpose of this article is to present our experience using a Foley catheter balloon for perioperative palatoplasty bleeding management. A retrospective data analysis was performed for all cases of palatoplasty performed by the author from 1999 to 2012 that experienced postoperative hemorrhage. These patients were managed by utilizing posterior nasal compression with a Foley catheter balloon for the period 2006 to 2012. We have compared two methods (we use before 2006 the reoperative method) with regards to the later development of palatal fistulae and cases with reoperative hemostasis. The study found no statistically significant differences between the conventional and proposed method in relation to the development of palatal fistulae (P=0.7). These findings suggest that nasal packing using a Foley balloon is a safe and effective method for postoperative bleeding control after palatoplasty in patients with cleft palate.

Scrapie is diagnosed antemortem in sheep by detecting misfolded isoforms of prion protein (PrP(Sc)) in lymphoid follicles of the rectal mucosa and nictitating membranes. Assay sensitivity is limited if (a) the biopsy is collected early during disease development, (b) an insufficient number of follicles is collected, or (c) peripheral accumulation of PrP(Sc) is reduced or delayed. A blood test would be convenient for mass live animal scrapie testing. Currently approved techniques, however, have their own detection limits. Novel detection methods may soon offer a non-animal-based, rapid platform with detection sensitivities that rival the prion bioassay. In anticipation, we sought to determine if diseased animals could be routinely identified with a bioassay using B lymphocytes isolated from blood sample volumes commonly collected for diagnostic purposes in small ruminants. Scrapie transmission was detected in five of six recipient lambs intravenously transfused with B lymphocytes isolated from 5~10 mL of blood from a naturally scrapie-infected sheep. Additionally, scrapie transmission was observed in 18 ovinized transgenic Tg338 mice intracerebrally inoculated with B lymphocytes isolated from 5~10 mL of blood from two naturally scrapie-infected sheep. Based on our findings, we anticipate that these blood sample volumes should be of diagnostic value.
