308 Evaluation and Comparison of Lung Volumes and Capacities in a Group of Morbid Obese, Obese and Eutrophic Adolescents

levels were evaluated in all patients. All assays were carried out in duplicate. Skin prick tests on the forearm were performed in all patients using standardized latex extract containing high ammonia natural rubber latex, and a full set of 35 common. In addition, venom SPT was performed on one patient based on the subject’s clinical history. Positive tests were counted as wheals of 3 mm in diameter after 20 minutes. Commercial extracts used were manufactured by Alyostal ST-IR. None of intradermal tests were performed. Results: The group of 30 patients included 10 male and 20 female subjects with vocal cord pathology, having a mean age of 39.87 years. Sixteen (53.3%) patients had vocal polyp, 10 (33.3%) had nodule, 4 (13.3%) had Reinke edema. The mean IgE levels was 133.73 IU/mL, and mean eosinophil levels was 10,728.3. Dermal prick tests were found to be positive in 66.7% of the patients): The most common allergen was mite (53.3%) and grass pollen (52.3%). Conclusions: In conclusion skin Prick tests were found to be highy positive in patients with bening lesions of vocal cords compared to normal population. Thus we can speculate that allergy may play a role in pathopysiology of these lesions. Further research is needed to identify the underlying pathways mediating the laryngeal response to allergy so that improved diagnostic and therapeutic techniques can be developed.
