7 and 8.3, respectively. The average rhinosinusitis disability index was 32.1. When stratified by the presence of pain-related comorbidities, there was no significant difference in Lund-Kennedy (p=0.203), Lund-MacKay (p=0.101), or rhinosinusitis disability index (p=0.421).

Although prior studies have suggested a correlation between the presence of pain-related comorbidities and worse chronic rhinosinusitis specific quality of life, this relationship was not evident within the current cohort of patients. The relationship between pain and sinusitis specific quality of life is likely complex and requires further research to fully elucidate.

Bioactive glass (S53P4), abbreviated BG, currently seems to be the best material for reconstructing the posterior wall of the auditory canal and obliterating the postoperative cavity.

The aim of the study was to report preliminary results of otosurgery involving obliteration of the mastoid cavity after canal wall down mastoidectomy.

11 adult patients who had had a history of chronic otitis media with cholesteatoma in one or both ears and previous canal wall down mastoidectomy. The duration of the follow-up was 6months, with routine visits after 7days, then 1, 3, and 6months after surgery. The patient’s medical history, noting other diseases potentially affecting the healing process, was analyzed. Healing, audiometric results, reduction of the volume of the cavity after surgery, and reduction of bacterial flora growth were assessed.

There was not worsening in the audiological evaluation. Healing period was uneventful. There was a reduction in volume of the postoperative cavity, no development of pathological flora, and no recurrence of cholesteatoma.

Obliteration of the mastoid process with S53P4 bioactive glass is a safe and effective method of treatment. Such a procedure should be considered as a treatment for patients after canal wall down surgery (CWD).

Such a procedure should be considered as a treatment for patients after canal wall down surgery (CWD).Nasal septoplasty and inferior turbinate reduction are common procedures performed in the treatment of nasal obstruction. These procedures are generally considered to be safe with minimal reported complications. Herein, we describe a case of a 43-year-old female who developed transient unilateral mydriasis following septoplasty with inferior turbinate reduction, likely due to the sympathomimetic agents used for vasoconstriction and mucosal decongestion.

To evaluate the role of the topical corticosteroid, mometasone furoate, nasal spray in the treatment of post COVID-19 anosmia.

A prospective, randomized, controlled trial was conducted among patients with post COVID-19 anosmia. One hundred patients were randomly assigned to two groups; group I included 50 patients received mometasone furoate nasal spray in an appropriate dose of 2 puff (100μg) once daily in each nostril for 3weeks with olfactory training, group II included 50 patients were advised to keep on olfactory training only. The assessment of smell was done using (Visual Analog Scale from 0 to 10). All patients were initially evaluated after their recovery from COVID-19 and followed up for 3weeks. The smell scores were recorded weekly and the duration of smell loss was recorded from the onset of anosmia till the full recovery.

In both groups, the smell scores significantly improved by the end of the third week (P < 0.001). By comparing smell scores between both groups after 1week, 2weeks, and 3weeks of treatment, there were no statistically significant differences between both groups. In group I, (62%) of patients completely recovered their sense of smell after 3weeks of treatment, compared to (52%) of patients in group II (P = 0.31).

The results suggested that using mometasone furoate nasal spray as a topical corticosteroid in the treatment of post COVID-19 anosmia offers no superiority benefits over the olfactory training, regarding smell scores, duration of anosmia, and recovery rates.

To deeply understand the role of antibodies in the context of Trypanosoma cruzi infection, we decided to characterize A2R1, a parasite antibody selected from single-chain variable fragment (scFv) phage display libraries constructed from B cells of chronic Chagas heart disease patients.

Immunoblot, ELISA, cytometry, immunofluorescence and immunohistochemical assays were used to characterize A2R1 reactivity. To identify the antibody target, we performed an immunoprecipitation and two-dimensional electrophoresis coupled to mass spectrometry and confirmed A2R1 specific interaction by producing the antigen in different expression systems. Based on these data, we carried out a comparative in silico analysis of the protein target´s orthologues, focusing mainly on post-translational modifications.

A2R1 recognizes a parasite protein of ~50kDa present in all life cycle stages of T. cruzi, as well as in other members of the kinetoplastid family, showing a defined immunofluorescence labeling pattern consistent with the cytoskeleton. A2R1 binds to tubulin, but this interaction relies on its post-translational modifications. Interestingly, this antibody also targets mammalian tubulin only present in brain, staining in and around cell bodies of the human peripheral and central nervous system.

Our findings demonstrate for the first time the existence of a human antibody against T. cruzi tubulin capable of cross-reacting with a human neural protein. This work re-emphasizes the role of molecular mimicry between host and parasitic antigens in the development of pathological manifestations of T. cruzi infection.
