Elastic fibers in Reinke's edema.

Objectives: We describe the distribution of elastic system fibers in the superficial layer of the lamina propria of Reinke's edema, as compared with normal vocal folds.

Methods: Weigert's resorcin-fuchsin stain after oxidation with 10% oxone was used to study the arrangement of elastic fibers. The findings were categorized and afterward compared with the severity of Reinke's edema.

Use of pyrolytic carbon coated beads (Durasphere) to treat glottic failure: an experimental study in dogs.

Unlabelled: There is no ideal tissue or substance to be injected in the vocal folds. The objective of the present study was to assess the use of Durasphere in canine vocal fold injection.

Materials And Methods: in six adult dogs we injected 0.

Disarrangement of collagen fibers in Reinke's edema.

Objective/hypothesis: To describe the arrangement of collagen fibers in the superficial layer of the lamina propria of the vocal folds with Reinke' edema.

Study Design: Cross sectional analysis of the lamina propria of the vocal folds with Reinke's edema (RE).

Method: The picrosirius polarization method was used to study the arrangement of collagen fiber.

Intraoral and transcutaneous cervical ultrasound in the differential diagnosis of peritonsillar cellulitis and abscesses.

Aims: The objective of the present study was to determine the specificity, sensitivity and accuracy of intraoral and transcutaneous ultrasound (US) in the diagnosis of peritonsillar cellulitis and abscess.

Study Design: Clinical-Prospective.

Material And Methods: Thirty nine patients were seen at the otorhinolaryngology emergency department of the University Hospital, of the School of Medicine, University of São Paulo, with a clinical diagnosis of peritonsillar cellulitis or abscess.

Microbiology of peritonsillar abscesses.

Aim: The objective of the present study was to analyze the microbiology of peritonsillar abscesses.

Methods: Thirty patients, mean age 24,2 years, with peritonsillar abscesses underwent aspiration of at least 3 mL of pus, which was cultured for aerobes and anaerobes.

Results: 87% samples showed positive cultures.

Role of rapid antigen detection test for the diagnosis of group-A beta-hemolytic streptococcus in patients with pharyngotonsillitis.

Unlabelled: Group A beta-hemolytic streptococcus (GAS) is an important pharyngotonsillitis etiologic agent. Correct etiologic diagnosis and early treatment prevent suppurative and non-suppurative complications of streptococcal pharyngotonsillitis, however, clinical diagnostic methods are not reliable. Within this context, rapid detection methods of GAS antigen are useful to diagnose this agent.

Brown tumor of the facial bones: case report and literature review.

Brown tumor, an uncommon focal giant-cell lesion, arises as a direct result of the effect of parathyroid hormone on bone tissue inpatients with hyperparathyroidism. The initial treatment involves the correction of hyperparathyroidism, which usually leads to tumor regression. We report a case of brown tumor of the right nasal fossa in a 71-year-old woman.

Auditory brainstem response and otoacoustic emission assessment of hearing-impaired children of mothers who contracted rubella during pregnancy.

Conclusions: Based on the auditory brainstem response (ABR) results obtained in this study, the incidence of deafness in children whose mothers had rubella during pregnancy is high (29.5%), and deafness is profound in most cases (80%). Vaccinating women of childbearing age against rubella is essential to reduce the number of cases of childhood sensorineural hearing loss caused by gestational rubella.
