ABSTRACT
Laryngotracheal stenosis develops when scar tissue forms in the trachea and, rarely, in the larynx itself. Symptoms depend on the degree of airway obstruction and can range from asymptomatic to upper airway obstruction severe enough to cause death. We report on 21 patients who underwent tracheal resection for severe stenosis. Resection remains a good option in this situation, and there is a minimal need for specialised postoperative care or intensive care unit admission in the majority of cases.
ABSTRACT
The aim of this study was to compare the histology of nasopharyngeal masses of HIV positive and HIV negative patients and to determine the prevalence of malignancy in nasopharyngeal masses in HIV positive patients. The records of all patients who had nasopharyngeal biopsies performed at the Department of Otorhinolaryngology, Universitas Academic Hospital between January 2006 and December 2011, were reviewed and 151 patients were identified. The HIV status of 110 of these patients was known: 78 (70.9 %) were HIV positive and 32 (29.1 %) were HIV negative. The CD4 count was known in 63 (80.8 %) of the HIV positive patients with the median CD4 count being 275 cells/µl (14-712 cells/µl). Most nasopharyngeal masses in HIV positive patients were benign. Malignancies were significantly more common in the HIV negative group than in the HIV positive group, with six (7.7 %) of the nasopharyngeal masses in the HIV positive group being malignant, while eight (25 %) of those in the HIV negative group were malignant. Most nasopharyngeal masses in HIV positive patients are due to lymphoid hyperplasia. The presence of large cervical lymphadenopathy should alert one to the possibility of a malignancy rather than a benign disease process.
