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. STUDY DESIGN: Clinical prospective with transversal cohort. MATERIAL AND METHODS: Prospectively, 39 patients with chronic rhinosinusitis, in use of antiretroviral therapy, were included in the present study and divided into two groups: patients with diagnosis of AIDS (group I) and those infected by HIV (group II). Clinical and laboratorial assessments, with CD4+ cell count and CT evaluation, were performed and compared among groups I and II. RESULTS: Group I and II presented mean CD4+ cell count of 118 cells/10-9l and 377 cells/10-9l, respectively. Comparison of the tomographic findings by the Lund-Mackay staging system presented a score of 12 for group I and 5.63 (pd" 0.001) for group II. Fever and postnasal discharge were more prevalent in group I (pd" 0.001). CONCLUSIONS: In our Service, prevalence of chronic rhinosinusitis in HIV-infected patients was 12%. AIDS patients had a higher incidence of fever and postnasal discharge than those of group II. Moreover, extensive radiological findings were prevalent in patients with AIDS (group I) than in HIV-infected individuals (group II).

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. STUDY DESIGN: Series study. MATERIAL AND METHOD: Between 1993 and 2004, 44 patients with cerebrospinal rhinorrhea were operated on using intranasal endoscopic approach in the University Hospital of the University of Sao Paulo, Medical School. The charts of all patients treated in our hospital were reviewed. RESULTS: Forty-four patients, 16 women (36%) and twenty-eight men (64%), were included in the study. Patients' ages ranged from 2 to 68 years (mean: 40.3 years). Etiology, site of leakage, diagnosis, technique, cause of failure and follow-up are discussed. CONCLUSION: The authors concluded that transnasal endoscopic surgery for CSF rhinorrhea had high success rate, low morbidity and stable long-term results.

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. MATERIAL AND METHOD: Ninety-four HIV infected patients (25 women and 69 men) with RAS were evaluated in the ENT Department of the University of Sao Paulo-Medical School from January 1998 to December 2003. The age ranged between 19 and 63 years (mean = 35.3 years). The patients were divided in two groups: AIDS group and HIV infected group. RESULTS: The patients with AIDS and HIV infection presented, respectively, eight ulcers and two ulcers by outbreaks. Similarly, patients with major RAS presented smaller counting of cells CD8+, CD4+ and CD4+/CD8+ cells, and higher mean value of viral load than the patients with herpetiform and minor RAS. Between patients with minor and herpetiform RAS there were no statistical differences. CONCLUSIONS: The emergence of the lesions, mainly in major RAS, is directly related to the immunological state of the HIV infected patient. These patients frequently present nutritional deficits and worsening in life style. Thus, diagnosis and treatment of RAS is a challenge that should not be neglected.

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 diagnosis is not reliable. Within this context, rapid detection methods of GAS antigen are useful to diagnose this agent. AIM: The objective of the present study was to determine sensitivity and specificity of rapid GAS antigen detection tests used in Brazil. STUDY DESIGN: Clinical prospective. METHOD: Eighty-one patients with clinical diagnosis of acute pharyngotonsillitis seen at the otorhinolaryngology emergency department of the University Hospital, FMUSP, between May 2001 and April 2002 were submitted to two simultaneous collections of oropharyngeal material using swabs. The rapid GAS antigen detection test was compared to culture on blood agar, the gold standard for the diagnosis of this etiologic agent. RESULTS: Among the 81 patients studied, the rapid test was positive in 56% and negative in 44%. GAS growth in culture was observed in 40.7% of the patients. Sensitivity and specificity of the rapid test were, respectively, 93.9% and 68.7%, and the negative and positive predictive values were 94.2 and 67.4%, respectively. CONCLUSIONS: We concluded that high sensitivity of the test allows its use in the identification of patients with GAS. Rapid streptococcal antigen detection tests have been shown to be an important adjuvant tool in the etiologic diagnosis of pharyngotonsillitis.

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. MATERIALS AND METHODS: we dissected the nasal fossae belonging to 25 cadavers. RESULTS: the average intranasal length of the anterior ethmoidal artery was 5.2 mm. The anterior ethmoidal canal presented some degree of dehiscence in 66.7%. The average distance between the artery middle point to the anterior nasal spine was of 61.72 mm (sd=4.18 mm); to the lateral nasal wall (nasal axilla) was of 64.04 mm (sd=4.69 mm); and from the anterior axilla to the middle turbinate was of 21.14 mm (sd=3.25 mm). For all the measures there was no statistically significant measures when both sides were compared (p>0.05). CONCLUSIONS: We concluded that the middle conchae axilla is the most reliable point of reference to locate the AEA.

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. After initial evaluation, all patients were submitted to intraoral and transcutaneous US. RESULTS: Intraoral US was performed on 35 cases and its sensitivity was of 95.2%, the specificity was of 78.5% and the accuracy was of 86.9%. Transcutaneous US was feasible in all 39 patients and diagnosed peritonsillar abscess in 53.8%. There were 5 false-negatives and 1 false-positive result, sensitivity was 80%, specificity was 92.8% and accuracy was 84.5%. CONCLUSION: Intraoral US was quite sensitive in the diagnosis of peritonsillar abscesses when performed by an experienced radiologist. Specificity was higher for transcutaneous US compared to intraoral US. However, when transcutaneous US was performed in patients with trismus, it was able to diagnose all peritonsillar abscesses, since they were large collections which are common in patients with trismus. These exams showed similar accuracy.
