Prevalence and clinical profile of fungal rhinosinusitis
There are only a few landmark studies from the Indian subcontinent on fungal rhinosinusitis. The lack of awareness among clinicians regarding the varying clinical presentations of fungal rhinosinusitis prompted us to undertake this study.
To determine the prevalence, etiologic basis, clinical features, radiologic features, and microscopic features of fungal rhinosinusitis, and to evaluate the various treatment modalities available.
This was a prospective study in which evaluation of 100 patients with chronic rhinosinusitis was done. Specimens collected were subjected to both microbiology and pathologic examination; data collected, including clinical and radiologic features, were analyzed by the Pearson χ2 test and Fisher's exact test.
The prevalence of fungal rhinosinusitis in our study was 30% (n = 30). Mucor was the most commonly isolated species (n = 15 [50%]) of fungus. Pathologic examination had a higher sensitivity (76.67%) compared with microbiology tests (50%) in the diagnosis of fungal rhinosinusitis. Fungus ball (n = 14 [46.6%]) was the most prevalent entity in the spectrum of fungal rhinosinusitis. Forty percent of cases (n = 12) were of invasive fungal rhinosinusitis. The prevalence of fungal rhinosinusitis was higher among individuals who were immunocompetent (n = 17 [56.6%]). Of patients who were immunocompromised, 84.6% (n = 11) had mucormycosis.
Unilateral involvement of paranasal sinuses was more in favor of fungal etiology. Complications were more common in fungal rhinosinusitis caused by Mucor species. Mucormycosis, a rare clinical entity, in subjects who were immunocompetent, had a high prevalence in our study.

In the fields of rhinology & allergy, as in all medical fields, there is a need for a greater number of journals which publish in the open access format. The underlying spirit of this format is to break down the barriers to knowledge sharing. Allergy & Rhinology, was created to serve this need; and is proud to take the lead in publishing quality research work as an experiment in the open format. As long as the fiscal model works, the Journal shall allow all users the right to freely read, download, copy, distribute, print, search, or link to the full texts of its articles.
The academic standard of Allergy & Rhinology is designed to be no different than traditional subscription-based, scientific and scholarly journals in that the quality of the research work which it publishes shall meet the rigors of peer-review and other scholarly quality controls.
