[Endoscopic ligation of the anterior ethmoidal artery: a cadaver dissection study].

Anterior ethmoidal artery (AEA) ligation may be necessary in cases of severe epistaxis not controllable with traditional therapy. Endoscopic endonasal ligation of the AEA is not used frequently; there are few studies in the literature for standardization of the endoscopic technique for this vessel. To demonstrate the feasibility of periorbital AEA ligation in a transethmoidal endoscopic approach.

Group psychotherapy: an additional approach to burning mouth syndrome.

Introduction: Glossodynia or burning mouth syndrome (BMS) is a common and poorly understood disorder. Its treatment is uncertain. Otherwise, there is some evidence of the importance of psychological factors in the genesis of this disease.

Rhinosinusitis in HIV-infected children undergoing antiretroviral therapy.

Unlabelled: The association of protease inhibitors (PI) to antiretroviral therapy has generated sensible changes in morbidity and mortality of HIV-infected patients.

Aim: Aims at evaluating the impact of this association on the prevalence of rhinosinusitis (RS) and CD4+ lymphocyte count in HIV-infected children.

Methods: Retrospective cross-sectional study of the medical charts of 471 HIV-infected children.

Sphenoid sinus symmetry and differences between sexes.

Objectives: To evaluate the anatomic variations of neurovascular structures adjacent to the sphenoid sinus and their agreement between right and left sides as well as differences between sexes.

Methods: Forty-five cadavers were dissected (24 men, and differences between sexes and agreement of anatomic variations of the sphenoid sinus between sides were analyzed.

Results: The mean distance from the sphenoid sinus ostium to the anterior nasal spine was greater in males than in females by an average of 3.

Yolk sac tumor in the nasal cavity.

Yolk sac carcinoma (YST) is rare malignant tumor of germ cell origin. It most commonly arises from the gonads but extragonadal sites of origin are reported in 20% of the cases. Head and neck germ cell tumors are uncommon and only a small number are malignant.

HAART impact on prevalence of chronic otitis media in Brazilian HIV-infected children.

Unlabelled: The advent of new antiretroviral drugs such as protease inhibitors has generated sensible changes in morbity and mortality in HIV-infected patients.

Objectives: To evaluate the impact of Highly Active Antiretroviral Therapy (HAART) on the prevalence of chronic otitis media in HIV-infected pediatric population.

Methods: We analyzed medical charts of 471 children aged zero to 12 years and 11 months with HIV infection from an Ambulatory of ENT and AIDS.

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.

Endoscopic anatomy of the anterior ethmoidal artery: a cadaveric dissection study.

Introduction: The anterior ethmoidal artery (AEA) is an important point of anatomical reference in order to locate the frontal sinus and the skull base. Notwithstanding, despite numerous endoscopic studies in cadavers, we still lack an anatomical study on the AEA in the western population.

Aim: to determine reference points used to locate the artery, study its relationship with the skull base and its degree of dehiscence, as well as to study intra and inter individual variations.

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.

Endoscopic dacryocystrhinostomy.

Unlabelled: Endonasal endoscopic dacryocystorhinostomy (EN-DCR) is now a well-established procedure to relieve nasolacrimal duct obstruction, becoming its domain for the ENT surgeons indispensable.

Aim: The aim of the present study is to report the experience of the Otorhinolaryngology Department of the University of São Paulo Medical School in the management of the obstruction of the drainage of the nasolacrimal system by EN-DCR, comparing with the results in literature.

Study Design: clinical retrospective.

Chronic rhinosinusitis in HIV-infected patients: radiological and clinical evaluation.

Unlabelled: The advent of protease inhibitors, which enhances the survival rate of HIV-infected individuals, leads patients to search for otorhinolaryngologists, as 40-70% of them may present some sort of otorhinolaryngological disorder.

Aim: We aimed at comparing the CT scan findings and the nasosinusal complaints of HIV-infected and AIDS patients with clinical diagnosis of chronic rhinosinusitis. The literature on the subject is revised and discussed.

AIDS and Recurrent Aphthous Stomatitis.

Unlabelled: The immunodeficiency state in HIV infected patients has been the cause of severe episodes of Recurrent Aphthous Stomatitis (RAS).

Aim: Our study aims to establish correlation between the manifestations of RAS and the immunosuppression state caused by HIV infection, through counting of CD4+ cells, CD8+ cells, CD4+:CD8+ cells ratio and viral load.

Study Design: Series study.

Endoscopic repair of CSF rhinorrhea: experience of 44 cases.

Unlabelled: Cerebrospinal fluid (CSF) rhinorrhea is a leakage of fluid from the subarachnoid space to the frontal, sphenoidal or ethmoidal sinuses. CSF rhinorrhea is a known potential complication with significant morbidity and mortality. It may present a significant challenge in diagnosis, localization and management.
