Background: The objective of this study was to compare the low-priced monopolar electrocautery to the high-priced, worldwide used, plasma ablation in tonsillotomy among children aged between three and twelve years, suffering from obstructive breathing disorders (OBD), with respect to post-operative pain, bleeding and related morbidities.

Methods: A randomized case-control study was conducted in the Eye and Ear Hospital International- Lebanon. 103 children aged between three and twelve years suffering from OBD secondary to tonsillar hypertrophy were randomly assigned into two groups. Post-operative pain was evaluated using age-adequate validated scales: "FLACC-R" (Face, Legs, Activity, Cry, Consolability-Revised) for children aged less than five years, and "Wong Baker faces" for older children. Additional post-operative outcomes were evaluated using Pain-PROM (Patient reported Pain-Related Outcome Measures) and TAHSI (Tonsil and Adenoid Health Status Instrument) scales.

Results: Significantly, higher rates of patients who underwent tonsillotomy via plasma ablation technique used analgesics and had severe pain compared to the monopolar electrocautery group. A longer operative duration was significantly associated with higher pain scores, and the plasma ablation technique yielded significantly higher operative mean durations. 10 days post-operatively, a significantly higher percentage of children reported an overall high pain severity and more than expected overall pain when using the plasma ablation technique compared to the monopolar electrocautery one. Overall bleeding rates were similar. No difference was reported one month post-operatively.

Conclusion: When compared to plasma ablation, monopolar electrocautery, can provide the same efficiency in relieving OBD in healthy children, with equal overall bleeding rates, but significantly lower cost, operating time, pain scores and need for analgesics.

Olfactory and taste dysfunctions in COVID-19.

Curr Opin Allergy Clin Immunol 2021 Feb 3. Epub 2021 Feb 3.

Purpose Of Review: Olfactory dysfunction (OD) can be a single and early prominent symptom of severe acute respiratory syndrome (SARS)-COV-2 infection unlike middle east respiratory syndrome (MERS) and SARS. OD data are very informative but many are not peer-reviewed, often inconclusive and may reveal variable and sometimes contradictory results. This is often due to incongruent data of subjective and objective OD testing. Mechanistic pathways of OD and taste dysfunction (TD) are slowly unveiling, not infrequently extrapolated from historical models of SARS and MERS and are still partly unclear.

Recent Findings: We reviewed the literature on OD and TD during the COVID-19 pandemic analyzing current data on pathogenesis and clinical correlates including prevalence, recovery rates, risk factors, and predictive power. Also, we evaluated various methods of subjective and objective olfactory testing and discussed challenges in management of patients with OD and rhinitis during the pandemic.

Summary: Subjective evaluation of smell disturbances during COVID-19 pandemic likely underestimates true prevalence, severity, and recovery rates of OD when compared to objective testing. OD is predictive of COVID-19 infection, more so when associated with TD. Recognizing inherent limitations of both subjective and objective OD and TD testing enables us better to manage chemosensory dysfunction in COVID-19 patients. Besides, current mechanistic data suggest neurotropism of COVID-19 for olfactory neuro-epithelium and a potential role of transient receptor potential (TRP) channels. Future studies are needed to explore further the neurogenic inflammation in COVID-19.

Immunopathological features of air pollution and its impact on inflammatory airway diseases (IAD).

World Allergy Organ J 2020 Oct 5;13(10):100467. Epub 2020 Oct 5.

INSERM U 1168, VIMA: Ageing and Chronic Diseases Epidemiological and Public Health Approaches, Villejuif, France.

Air pollution causes significant morbidity and mortality in patients with inflammatory airway diseases (IAD) such as allergic rhinitis (AR), chronic rhinosinusitis (CRS), asthma, and chronic obstructive pulmonary disease (COPD). Oxidative stress in patients with IAD can induce eosinophilic inflammation in the airways, augment atopic allergic sensitization, and increase susceptibility to infection. We reviewed emerging data depicting the involvement of oxidative stress in IAD patients. We evaluated biomarkers, outcome measures and immunopathological alterations across the airway mucosal barrier following exposure, particularly when accentuated by an infectious insult.

International expert consensus on the management of allergic rhinitis (AR) aggravated by air pollutants: Impact of air pollution on patients with AR: Current knowledge and future strategies.

World Allergy Organ J 2020 Mar 3;13(3):100106. Epub 2020 Apr 3.

Department of Otolaryngology- Head and Neck Surgery, Eye and Ear University Hospital, Beirut, Lebanon.

Allergic rhinitis affects the quality of life of millions of people worldwide. Air pollution not only causes morbidity, but nearly 3 million people per year die from unhealthy indoor air exposure. Furthermore, allergic rhinitis and air pollution interact. This report summarizes the discussion of an International Expert Consensus on the management of allergic rhinitis aggravated by air pollution. The report begins with a review of indoor and outdoor air pollutants followed by epidemiologic evidence showing the impact of air pollution and climate change on the upper airway and allergic rhinitis. Mechanisms, particularly oxidative stress, potentially explaining the interactions between air pollution and allergic rhinitis are discussed. Treatment for the management of allergic rhinitis aggravated by air pollution primarily involves treating allergic rhinitis by guidelines and reducing exposure to pollutants. Fexofenadine a non-sedating oral antihistamine improves AR symptoms aggravated by air pollution. However, more efficacy studies on other pharmacological therapy of coexisting AR and air pollution are currently lacking.
