RESUMO

INTRODUCTION: Macrolides used as immunomodulators are a promising tool for chronic inflammatory airway diseases. Eosinophilic nasal polyposis (ENP) is still considered a disease that is difficult to control with the currently standardized treatments. OBJECTIVES: To evaluate prolonged treatment with low-dose azithromycin for ENP based on clinical and histopathologic variables. METHODS: The present investigation was a self-paired case study of 33 patients with ENP. A comparison was performed between patients before and after treatment with azithromycin for 8 weeks. The patients were subjected to clinical examinations, staging (three-dimensional imaging by endoscopy), application of the questionnaire, and biopsy of nasal polyps at the beginning and at the end of the treatment. RESULTS: The treatment yielded a clinical improvement regarding the two variables studied: polyposis staging (69.7%) and questionnaire (57.6%). We did not find significant differences in the inflammatory pattern and in the percentage or absolute number of eosinophils per field between samples obtained before and after the treatment (p > 0.05). There was no difference between the answers obtained from groups with and without asthma and/or aspirin intolerance (p > 0.3). The patients with advanced initial staging exhibited lower subjective improvement index and staging reduction (p = 0.031 and p = 0.012, respectively). CONCLUSION: Based on this study, azithromycin may be considered as another therapeutic option for ENP. However, further studies are necessary to define the real mechanism of action involved.

RESUMO

OBJECTIVE: To evaluate the results of partial and total ossicular reconstruction prostheses entirely made of hydroxylapatite. STUDY DESIGN: A retrospective review of cases followed-up between 1997 and 2000. SETTING: Tertiary referral center. PATIENTS: One hundred adult patients (60 men and 40 women) were studied. The mean age was 55 years (range, 25 to 65 years). Fifty patients had a previous tympanoplasty. The series included 45 cholesteatomas (45%), 37 chronic otitis media without cholesteatoma (37%), 13 retraction pockets (13%), and 5 posttraumatic ossicular displacements (5%). INTERVENTION: A one-stage ossiculoplasty with a partial ossicular reconstruction prosthesis (n = 65) or a total ossicular reconstruction prosthesis (n = 35) was performed. This was associated with a simple mastoidectomy in 70 cases and a radical mastoidectomy in 10 cases. MAIN OUTCOME MEASURES: All patients were followed-up at 1 year, and 50 were reexamined 2 years after surgery. Clinical and audiometric data were collected in a database at each visit. RESULTS: A prosthetic extrusion was noted in two cases (2%). A prosthetic displacement occurred in 10 cases (10%). A revision surgery was carried out in 10 cases because of an ossiculoplasty failure or a disease recurrence. At 1 year, the residual air-bone gap was lower in cases with a partial ossicular reconstruction prosthesis than those with a total ossicular reconstruction prosthesis (16 +/- 9.3 versus 23 +/- 13.7 dB, p < 0.05). The gain in mean air conduction threshold was 21 +/- 12.8 dB in cases of partial ossicular reconstruction prosthesis and 19 +/- 11.3 dB in cases of total ossicular reconstruction prosthesis (not significant). Revision surgery, canal wall-down mastoidectomy, or cholesteatoma yielded poorer functional results. CONCLUSION: Partial ossicular reconstruction prosthesis and total ossicular reconstruction prosthesis entirely made of dense hydroxylapatite yielded high rates of air-bone gap reduction and high anatomic stability.
