“…Another structural target is the nasoseptal swell body, with newer interventions directed toward volumetric reduction to improve airflow. Though ablation of the swell body (whether through radiofrequency, laser, or coblation) has shown promise in reducing symptoms, 2382–2386 its effectiveness has yet to be tested with an AR‐specific cohort. However, the advent of devices intended for office use (e.g., Vivaer, Aerin Medical, Sunnyvale, CA) may provide opportunities for further study.…”

Background In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR‐Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR‐Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence‐based findings and recommendation from the full document. Methods ICAR‐Allergic Rhinitis 2023 employed established evidence‐based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. Results ICAR‐Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. Conclusion The ICAR‐Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

BackgroundImproved nasal airway obstruction (NAO) symptoms were reported at 3 months following temperature‐controlled radiofrequency (TCRF) treatment of the septal swell body (SSB). This report provides results from assessments of the long‐term safety and efficacy of TCRF treatment of SSB hypertrophy to treat NAO through 12 months posttreatment.MethodsThis prospective, multicenter, long‐term, open‐label study was conducted in nine centers within the United States and included patients with severe/extreme NAO attributed to SSB hypertrophy. Outcome measures included assessments of Nasal Obstruction Symptom Evaluation Score (NOSE), Numeric Rating Scale (NRS) ease‐of‐breathing, patient satisfaction, and adverse events at 6 and 12 months.ResultsOf the 70 patients treated, 65 and 62 patients completed the 6‐ and 12‐month follow‐up assessments. Compared to baseline, there was a 67.5% decrease in adjusted mean NOSE scores at 6 months (mean change −49.6, 95% confidence interval [CI] −54.8 to −44.4; p < 0.001) and a 65.4% decrease at 12 months (mean change −48.1, 95% CI −53.7 to −42.5); p < 0.001), which is consistent with previously published 3‐month results. A 62.0% and 62.5% improvement compared to baseline was observed in the NRS ease‐of‐breathing score at 6 and 12 months, respectively (p < 0.001). No serious adverse were reported overall and no new device‐ or procedure‐related adverse events were reported in the interval between 3 and 12 months posttreatment.ConclusionTCRF treatment of SSB hypertrophy has a significant and durable effect on improving the symptoms of NAO and health‐related quality of life in patients with symptoms of nasal obstruction and congestion through 12 months postprocedure.

Effect of laser irradiation on a heavy crude oil sample: Changes in viscosity and implications for oil recovery and transport

et al. 2022

Heavy high viscosity oil is becoming an attractive source of energy, however, a reduction in the viscosity of the oil is needed to aid in the recovery and transportation of the oil. In this study, a solid laser operating at 532 nm was employed to irradiate an oil sample contained in a small quartz cuvette equipped with two Cu rod electrodes as a sensor system. A reduction in the sample viscosity and changes in voltage and temperature were observed on laser irradiation due to the thermal processing effect. To study the effects of laser processing at different bias currents, the effects of varying the voltage and temperature in the absence of laser irradiation were also studied. An exponential function was used to fit the voltage waveforms, which underwent decay, to clarify the effects of laser irradiation on the crude oil. Particular attention was given to the relationships between the voltage, temperature, and viscosity. It was considered that the particles in the crude oil absorbed the laser energy, and this gave rise to heating effects thus causing changes in the temperature and electrical conductivity of the sample. Laser technology can be expected to be an important driving force in the future for achieving reductions in sample viscosity and this should eventually aid in the recovery and transport of crude oils.
