Infantile recurrent parotitis: follow up study of five cases and literature review.

UNLABELLED: Recurrent parotitis (RP) is defined as recurrent parotid inflammation, generally associated with non-obstructive sialectasis of the parotid gland. It is a rare condition, and its etiology remains an enigma. AIM: The purposes of the present study were (1) to relate the follow up of five RP cases; (2) to examine the role of sialography and ultrasound in diagnosis and follow up; and (3) to make a literature review. STUDY DESIGN: Series review. MATERIAL AND METHOD: We reviewed all recurrent parotitis cases from the files of the Otolaryngology Division at University of Sao Paulo, Brazil. The criteria for inclusion were at least two years of evolution and more than one year and a half follow-up in our service. We included five children in the study. Sialography was performed in the first evaluation and sonography was executed annually. Recurrent parotitis showed male predominance, and affected mainly children between the ages of 3 and 6. Frequency of crisis improved with time in all cases. Sialography showed sialectasis aspect in the affected glands and sonographic exams demonstrated hypoechoic and heterogeneous internal echoes. One case showed regression of ultrasound changes after clinical improvement.

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).

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.

Cicatricial pemphigoid: report of five cases.

Cicatricial pemphigoid is a chronic, systemic, autoimmune disease characterized by progressive bullous skin and mucous membrane lesions that tend toward scarring and involution. Manifestations of cicatricial pemphigoid include oral mucosal bullous lesions in 85 to 90% of patients, ocular mucosal lesions in 66%, nasal mucosal lesions in 15 to 23%, and laryngeal involvement in 8 to 21%. We report five cases of cicatricial pemphigoid in which all patients had ENT manifestations--specifically, oral and nasal mucosal involvement. Three of these patients also had laryngeal lesions; one of the three had a large laryngeal ulceration and bullae that caused a laryngeal stenosis and necessitated a tracheostomy. In addition to the five case reports, we also review the literature and discuss the pathogenesis, diagnosis, and treatment of this uncommon disease.

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. Children were divided according to the age: 0 to 5 years and 11 months and 6 to 12 years and 11 months and classified as having chronic otitis media based on history, physical examination, audiologic and tympanometric data. Prevalence of chronic otitis media, as well as CD4+ lymphocyte count were compared between groups in use of HAART and the group without HAART. RESULTS: Out of 459 children, 65 (14.2%) had chronic otitis media. We observed that in children aged 0 to 5 years and 11 months who were taking HAART there was significant lower prevalence of chronic otitis media (p=0.02). The use of HAART was associated to higher mean CD4+ lymphocyte count (p<0.001). CONCLUSION: The use of HAART was associated to reduction in prevalence of chronic otitis media in HIV infected children, probably due to increase in mean CD4+ lymphocyte count.
