Impact of mitomycin C on the mRNA expression signatures of immunological biomarkers in eosinophilic nasal polyposis.

Background: The topical application of mitomycin C has been evaluated as a complementary therapy for eosinophilic nasal polyposis (ENP). However, the mechanism underlying the additional benefits of mitomycin C for the control of eosinophilic inflammation and prevention of posttherapeutic relapse remains to be elucidated. In this work, the aim was to characterize the gene expression profile by quantitative real-time polymerase chain reaction (qPCR) of proinflammatory and regulatory biomarkers that are typically associated with ENP and to assess the impact of the topical application of mitomycin C on the nasal mucosal tissue immunologic milieu after ENP surgery.

Reproducibility of the three-dimensional endoscopic staging system for nasal polyposis.

Unlabelled: Nasal polyposis is a chronic inflammatory process of the nasal mucosa, characterized by multiple and bilateral nasal polyps. Different drugs have been used in its treatment. In order to study the results of different treatment modalities it is necessary to have some kind of staging.

Cheilitis granulomatosa associated with Melkersson-Rosenthal syndrome.

Melkersson-Rosenthal syndrome (MRS) consists of persistent or recurrent orofacial edema, relapsing facial palsy and fissured tongue. The complete triad of symptoms is uncommon, varying from 8 to 25%. The presentation of only one symptom is more common.

Gastric emptying of solids and semi-solids in morbidly obese and non-obese subjects: an assessment using the 13C-octanoic acid and 13C-acetic acid breath tests.

Background: It has been suggested that obesity is associated with an altered rate of gastric emptying. The objective of the present study was to determine whether the rates of solid and semi-solid gastric emptying differ between morbidly obese patients and lean subjects.

Methods: The Gastric-emptying time (GET) of solid and semi-solid meals were compared between lean healthy subjects and morbidly obese patients enrolled in two previously published studies.

Effect of mitomycin C in eosinophilic nasal polyposis, in vivo: concentration of IL5 and GM-CSF, RT-PCR.

Unlabelled: Eosinophilic nasosinusal polyposis is a chronic inflammatory infection with elevated infiltration of eosinophils, which presents high rate of recurrence after surgical treatment. The continuous inflammatory process that leads to the formation of polyps requires constant clinical treatment. Contributing to the maintenance of eosinophilia are cytokines IL5 (interleukin-5) and GM-CSF (granulocyte macrophages colony-stimulating factor), which show up in elevated concentrations.
