[Plants with antiviral properties used in Otorhinolaryngology].

Viruses represent one of the main causes of human morbidity and mortality worldwide. Plants have been used since time immemorial to treat, cure or alleviate diseases. We present some of them that make compounds with antiviral action and are used in traditional medicine.

Risk Factors Associated with Mortality among Patients with COVID-19: Analysis of a Cohort of 1213 Patients in a Tertiary Healthcare Center.

The presence of cardio-metabolic and respiratory comorbidities, immunosuppression, and chronic kidney disease have been associated with an increase in mortality from COVID-19. The objective of this study is to establish the risk factors associated with 30-day mortality in a cohort of hospitalized patients with COVID-19. This paper conducts a retrospective and analytical study of patients hospitalized for COVID-19 in a tertiary care center.

Diagnostic accuracy of symptoms as a diagnostic tool for SARS-CoV 2 infection: a cross-sectional study in a cohort of 2,173 patients.

Background: The SARS-CoV-2 pandemic continues to be a priority health problem; According to the World Health Organization data from October 13, 2020, 37,704,153 confirmed COVID-19 cases have been reported, including 1,079,029 deaths, since the outbreak. The identification of potential symptoms has been reported to be a useful tool for clinical decision-making in emergency departments to avoid overload and improve the quality of care. The aim of this study was to evaluate the performances of symptoms as a diagnostic tool for SARS -CoV-2 infection.

[Loss of smell, a preliminary indicator of COVID-19].

Some reports have been recently published on olfactory loss in people with severe COVID-19. It is suggested to take into consideration the recommendations of the American Academy of Otolaryngology and the British Association of Otorhinolaryngology to include olfactory loss as an early clinical symptom of COVID-19 and consider sudden olfactory loss, as a high index of suspicion of SARS-CoV-2 infection. It can be established that the majority of patients with olfactory loss due to COVID-19, present hyposmia and not anosmia.

A Case of Fatal Rhino-Orbital Mucormycosis Associated With New Onset Diabetic Ketoacidosis and COVID-19.

Mucormycosis is an invasive fungal infection, often acute and extremely severe, occurring in patients with an underlying condition. Coinfection in patients with coronavirus disease 2019 (COVID-19) has been reported, often bacterial. A 24-year-old female is presented with acute fatal rhino-orbital mucormycosis and COVID-19.

Evaluation of predictive value of olfactory dysfunction, as a screening tool for COVID-19.

Objectives: At the end of 2019, SARS-CoV-2 was identified, the one responsible for the COVID-19 disease. Between a 5.1% and a 98% of COVID-19 patients present some form of alteration in their sense of smell.

Broncho-Vaxom® (OM-85 BV) soluble components stimulate sinonasal innate immunity.

Background: Broncho-Vaxom® (OM-85 BV) is an extract of infectious respiratory bacteria that is used as an immunostimulant outside of the United States for the prevention and treatment of bronchitis and rhinosinusitis. Prior studies have shown that use of OM-85 BV is associated with reduction in frequency of respiratory infection and decreased duration of antibiotic usage. However, the effects of OM-85 BV on respiratory mucosal innate immunity are unknown.

[Experience in the surgical treatment of paranasal sinus mucoceles in a university hospital].

Background: Mucoceles are benign cystic lesions of the paranasal sinuses. Endoscopic marsupialisation is considered the first choice of treatment, due to its low morbidity and recurrence rates.

Objective: To establish the number of patients with recurrence, who were diagnosed clinically or by computed tomography, and who were submitted to surgery in the Ear, Nose and Throat Unit in a tertiary university hospital.

[Complications of endoscopic nasal and sinus surgery: experience in 150 patients].

Background: Endoscopic nasal and sinus surgery has been used greatly for the treatment of inflammatory and neoplasm pathology, as well as for the approach of the extrasinus structures. Although it has proven to be a very successful method, it is not exempt of complications. Our objective was to identify the frequency of complications in patients with sinus and nasal pathology that underwent an endoscopic surgery of the nose and sinuses.

[Evolution of maxillary sinus surgery in a university hospital].

Background: Maxillary sinus surgery has been evolving and, due to advances in technology, endoscopic surgery is widely used in the maxillary sinus for multiple pathologies that 15 years ago were treated through open approaches. For this reason, we conducted an observational descriptive study.

Methods: We reviewed the clinical records of patients with pathology involving the maxillary sinus and who were surgically treated from January 2008 to December 2009, type of disease, surgical approach used, presence of complications, pre- and postoperative score according to the Lund-Mackay scale, and resolution (or not) of symptoms.

[Chronic invasive rhinocerebral mucormycosis].

Rhinocerebral mucormycosis is a fulminant fungal disease that typically presents acutely in patients with diabetic ketoacidosis or immunosuppression. The case of a 55 year-old male patient is presented; the patient experienced chronic infection that involved nose, paranasal sinuses, hard palate, orbit, pterygopalatine fossa, infratemporal fossa with cavernous sinus thrombosis and compression of the internal carotid artery which develops in insidious manner after metabolic imbalance with predominantly ocular symptoms. The patient was managed with Amphotericin B and radical surgical debridement of affected tissue, the patient presenting cure without complications or added disabilities.
