Analysis of the Agger nasi cell and frontal sinus ostium sizes using computed tomography of the paranasal sinuses.

Unlabelled: The Agger nasi cell (ANC) and the frontal sinus ostium (FO) are important structures that can influence the anatomy and physiology of the frontal recess. The aim of this study was to evaluate the presence and size of ANC and the FO and correlate them according to gender, race and among themselves.

Method: A prospective study with 40 patients who underwent CT of the paranasal sinuses with sagittal reconstruction.

Cholesteatoma gene expression of matrix metalloproteinases and their inhibitors by RT-PCR.

Unlabelled: Acquired middle ear cholesteatoma is a benign keratinizing hyperproliferative squamous epithelial lesion that may result in the destruction of the bone structures surrounding the temporal bone. Recent studies show that variations in cellular production of matrix metalloproteinases (MMPs) and their specific inhibitors (TIMPs) contribute to the pathophysiology of cholesteatoma.

Objective: This study aims to analyze the use of RNA amplification tests to evaluate the expression of MMP and TIMP isoforms in cholesteatomas and their correlation with disease severity.

Futura study: evaluation of efficacy and safety of rupatadine fumarate in the treatment of persistent allergic rhinitis.

Unlabelled: Allergic rhinitis affects 10-30% of the population, negatively impacting one's quality of life and productivity. It has been associated with sinusitis, otitis media, sleep disorders, and asthma. Rupatadine is a second generation antihistamine with increased affinity to histamine receptor H1; it is also a potent PAF (platelet-activating factor) antagonist.

Antibiotic use in post-adenotonsillectomy morbidity: a randomized prospective study.

Unlabelled: Tonsillectomy with or without adenoidectomy still is one of the most commonly performed surgical procedures in the world, mostly in the pediatric population.

Aim: to study the impact of amoxicillin for 7 days in post-adenotonsillectomy recovery, comparing results with a control group.

Study Type: prospective, randomized, controlled study with 120 patients.

[Brainstem auditory evoked potentials as a method to assist the diagnosis of brain death].

Background: brainstem auditory evoked potentials in brain death.

Aim: to verify the agreement between the response in the auditory brainstem audiometry and the clinical outcome, analyzing the pattern of responses to electric stimulation.

Method: a cross-sectional study performed in 30 patients with Glasgow coma score of 3, submitted to the auditory brainstem audiometry and followed up until their clinical outcome: recovery or death.

Burning mouth syndrome: etiology.

The Burning Mouth Syndrome (BMS) is an oral mucosa pain--with or without inflammatory signs--without any specific lesion. It is mostly observed in women aged 40-60 years. This pain feels like a moderate/severe burning, and it occurs more frequently on the tongue, but it may also be felt at the gingiva, lips and jugal mucosa.

Tympanoplasty: surgical results and a comparison of the factors that may interfere in their success.

Unlabelled: Chronic otitis media has a high prevalence on the population and their treatment continuous to be a challenge for the otorhinolaryngologists.

Aim: To demonstrate the factors that could interfere in the tympanoplasty success and the surgical results during 2002.

Study Design: Clinical prospective.

Efficacy and safety of Sultamicillin (Ampicillin/Sulbactan) and Amoxicillin/Clavulanic acid in the treatment of upper respiratory tract infections in adults--an open-label, multicentric, randomized trial.

Unlabelled: Upper respiratory tract infections are the most common causes of medical visits in children and adults, demanding massive use of antibiotics. Bacterial resistance caused by beta-lactamase is one of the most serious problems in this matter. Sultamicillin, a double pro-drug of Ampicillin/Sulbactan, is a potent beta-lactamase inhibitor which can face this challenge.

Pre and postoperative psychological profile of children submitted to adenoidectomy and/or tonsillectomy.

Unlabelled: Adenoidectomy and/or tonsillectomy are the most frequent surgeries in otorhinolaryngology. Infantile psychological trauma may be caused by surgeries and anesthesia.

Aim: To estimate the preoperative service offered to children and their responsible people by examining their psychological profile pre and postoperatively.
