OBJECTIVES Floseal, a novel hemostatic sealant composed of collagen-derived particles and topical bovine-derived thrombin, is applied as a high-viscosity gel for hemostasis. This study is a prospective, randomized, controlled clinical trial of Floseal compared with nasal packing in patients with acute anterior epistaxis. STUDY DESIGN Institutional review(More)
This study examines the temporal pattern of hair cell loss in the chick basilar papilla following ten days of gentamicin administration in hatchling chicks. Chicks were subsequently killed at ages 11, 18, 25, and 32 days. The basilar papillae were embedded in plastic and serially sectioned for light microscopic analysis. Hair cell counts were obtained at(More)
Cryptococcosis in México is caused by both species of the Cryptococcus species complex i.e., Cryptococcus neoformans and C. gattii. The current study was aimed to determine genetic variability of 72 Mexican clinical isolates using PCR-fingerprinting with the primer M13. PCR fingerprinting revealed 55 VNI, five VNII, three VNIII, one VNIV, two VGI, two VGII,(More)
OBJECTIVES Diagnostic accuracy of the ThinPrep process (Cytyc, Boxborough, MA) was compared with that of conventional (smear) cytopreparation for fine-needle aspiration (FNA) of head and neck masses. METHODS In a prospective, randomized, single-blinded study, 209 patients served as their own controls and underwent 236 FNAs using ThinPrep and conventional(More)
The detrimental effects of transfusion have been documented--particularly by surgical oncologists, who believe transfusion-induced immunosuppression increases the incidence of recurrence and infectious complications. We examined this relation in surgical oncology of the head and neck. After meeting strict inclusion criteria, 104 patients were entered into(More)
A number of histopathologic parameters in squamous cell carcinoma of the oral cavity and oropharynx have been identified as having a statistically significant correlation with regional lymph-node metastasis. These parameters have been inconsistent and not readily reproducible. In an attempt to confirm these parameters, a retrospective analysis of 22(More)
Thyroglossal duct cysts (TDCs) are common congenital abnormalities of thyroid development. Carcinoma occurs rarely in patients with TDCs. In a large case series drawn from medical records at a health maintenance organization from 1971 through 1995, 14 cases of carcinoma in a TDC were found. This represents the largest known reported case series to date.(More)
Forty-four children who underwent adenotonsillectomy for obstructive sleep apnea (OSA) were studied. The diagnosis was confirmed polysomnographically. Patients with other medical problems or complications of OSA were excluded. The overall complication rate was 32%. Significant airway complications occurred in 16%. Factors associated with development of(More)
PROBLEM ADDRESSED Floseal is a novel matrix hemostatic sealant composed of collagen-derived particles and topical bovine-derived thrombin. It is applied as a high-viscosity gel for hemostasis and has been clinically proven to control bleeding. This study is a prospective, randomized, controlled clinical trial of Floseal sealant compared to traditional(More)
BACKGROUND The objective of this study was to determine the extent of interest in international electives among prospective otolaryngology residents and to determine whether the availability of international electives affected students' interest in ranking a particular residency program. METHODS A 3-part survey was given to all medical students enrolled(More)
