Rinitis atrófica / Atrophic rhinitis

La rinitis atrófica es una enfermedad crónica y progresiva de etiología desconocida. Se caracteriza por atrofia de la mucosa nasal y hueso subyacente, dilatación anormal de las cavidades nasales, obstrucción nasal paradójica, y formación de secreciones viscosas y costras secas; produciendo fetidez. Sus manifestaciones clínicas más frecuentes son obstrucción nasal, secreción purulenta, costras nasales y mal olor nasal. Se ha separado en dos entidades: primaria y secundaria. El tratamiento es principalmente conservador, y se han propuesto diversas terapias farmacológicas y quirúrgicas. La rinitis atrófica unilateral es una condición infrecuente, con escasos reportes en la literatura científica. Se puede asociar a la desviación septal, por lo que su corrección quirúrgica es una alternativa terapéutica disponible.

Atrophic rhinitis is a chronic disease of unknown etiology. This condition is characterized by progressive nasal mucosal and underlyng bone atrophy, abnormal widening of the nasal cavities, paradoxical nasal congestion and formation of viscid secretions and dried crusts, leading to a characteristic fetor (ozaena). The main clinical manifestations include nasal obstruction, purulent discharge, daily nasal crusting, nasal dryness and foul smell. It has been divided into two separate entities; primary and secondary. Treatment is mostly conservative, although pharmacological and surgical therapies have been proposed. Unilateral atrophic rhinitis is an uncommon condition, with few reports in the scientific literature. It is associated with septum deviation, so surgical correction is one of the therapeutic options available.

Prevalence and morphology of tritrichomonas suis from the nasal cavity of domestic pigs, sus scrofa, without atrophic rhinitis in the southern Brazil

The Tritrichomonas suis (Gruby and Delafond) that occur in the nasal cavity of domestic pigs. Sus scrofa, was isolated, described and its prevalence studies in healthy swine of different areas of Rio Grande do Sul, Brazil. The parasite protozoa was found in 2 of 208 cultures of nasal washings, representing a prevalence of 0.96 porcent. The morphology study of the live specimens done by phase contrats microscopy, dark field microscopy and by examination of fresh and stained specimens, showed that the T. suis isolated has the same morphological characteristics as the nasal cavity of trichomonads described by othe authors
