ABSTRACT
Oral cancer; the sixth most common malignancy in the world has one of the lowest 5 year survival rates. This can be attributed mainly to the delay in diagnosis. The purpose of this study was to evaluate the efficacy of vital staining with toluidine blue dye as an adjunct to standard clinical examination to facilitate early detection of malignant lesions of oral cavity and oropharynx. A hospital based diagnostic test accuracy study was carried out on 55 subjects with oral mucosal disorders that included clinically suspicious premalignant or malignant lesions, in the Department of ENT, Academy of Medical Sciences, Pariyaram, Kannur, Kerala over a period of 2 years. All lesions were subjected to detailed clinical examination and toluidine blue staining; and dye retention was recorded with photographs. The results of staining were compared with findings on histopathological examination. The Sensitivity and specificity of toluidine blue test for the detection of malignancy was 92.6 and 67.9% respectively; and the overall diagnostic accuracy was 80%. The result was highly significant with a 'p value' <0.001. The results indicate that toluidine blue staining is a simple, non-invasive technique which can be a valuable adjunct in the diagnostic process of oral and oropharyngeal cancers.
ABSTRACT
Chronic rhinosinusitis is one of the commonest health problem encountered in rhinology. Of these allergic fungal rhinosinusitis forms a significant group of patients. Patients commonly present with typical symptoms of sinusitis and the diagnosis is often made after imaging and/or intraoperatively. We report a rare case of allergic fungal sinusitis (AFS) caused by Chrysosporium species in a 70-year-old male with no co-morbidities. The fungus was isolated from allergic mucin collected from the sinuses. Therapy with intravenous Voriconazole was given leading to good relief for the patient, and no recurrences have occurred till date. Infections caused by Chrysosporium species are very rare, and is very rarely been reported to cause sinusitis in humans.
