1. MATERIALS AND METHODS

In a prospective case control study, 128 consecutive patients with BD (according to Iran or Japan criteria) and 139 non-BD controls from the orthopedic clinic (age and sex matched) were studied regarding previous T/A. A complete ENT clinical examination was performed for all of them. A computerized form, including 68 clinical and paraclinical data, was used to collect data about this examination and different manifestations of the disease. Comparison was made between 2 groups by chi square test and Fisher test. A confidence interval at 95%(CI) was calculated for each item.

T/A was performed in 6 patients with BD (4.7%, CI: 3.8) and 10 controls (7.2%, CI: 4.2) with no significant difference (p= 0.26). Positive history of recurrent throat infections was significantly higher (p= 0.005) in BD patients (27%, CI: 7.7 vs. 13%, CI: 5.6). This was true for herpes simplex infection (39%, CI: 8.4 vs. 30%, CI: 8.1), but not statistically significant (p= 0.93). No difference was found in the prevalence of tonsils (17%, CI: 6.5 vs. 17%, CI: 6.2, p= 0.99) or adenoids hypertrophy (4%, CI: 3.4 vs. 1%, CI: 1.7, p= 0.18). Different manifestations of the disease did not show any significant difference between BD patients with and without antecedent T/A (Table 1).
