Radiofrequency ablation can benefit patients who are not ideal candidates for surgical intervention and for whom conservative management has been unsatisfactory. Currently, radiofrequency ablation is performed using either ultrasonography or fluoroscopy. In this technique review, we propose a method of performing cooled radiofrequency ablation of the genicular nerves that uses both ultrasonography and fluoroscopy and that could be helpful for novice pain practitioners. <b>Case Series:</b> We report the experience of 2 patients with grade 4 osteoarthritis knee joints who underwent our cooled radiofrequency ablation technique. Each patient received a diagnostic block using ultrasonography, with ≥70% pain relief the prerequisite for performing cooled radiofrequency ablation. Our radiofrequency ablation technique involves using ultrasonography to identify and mark the superomedial, superolateral, and inferomedial genicular arteries. The marking done with ultrasonography is used during needle insertion with fluoroscopy guidance to reach the target points, and the final position of the needle is confirmed using sensory and motor stimulation before the cooled radiofrequency ablation procedure is performed. The cooled radiofrequency ablation resulted in pain reduction as measured on the visual analog scale and the Western Ontario and McMaster Universities Osteoarthritis Index scores at both patients' 3- and 6-month follow-ups. <b>Conclusion:</b> Using this technique for cooled radiofrequency ablation of the genicular nerves might help to reduce radiation exposure, specifically when the procedure is being performed by novice practitioners with limited experience.</p>","PeriodicalId":47600,"journal":{"name":"Ochsner Journal","volume":"24 4","pages":"303-308"},"PeriodicalIF":1.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11666106/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142886089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-risk-other HPV status was determined with the cobas HPV Test (Roche Diagnostics, North America) that identifies 12 high-risk, non-16/18 HPV genotypes. We hypothesized that we would find genotypes of HPV in our population that are not covered by the 9-valent HPV vaccine. <b>Methods:</b> For this retrospective cohort study, we randomly selected 50 high-risk-other HPV Pap test samples from 2018 from our pathology department registries for HPV genotype determination by Roche Linear Array (Roche Diagnostics, North America). Then we randomly selected 76 cervical biopsy samples of HGSIL or cervical cancer with high-risk-other HPV or HPV unknown status from 2016 to 2022 for HPV genotype determination by next-generation sequencing. Results are reported as counts and frequencies. <b>Results:</b> In the 50 high-risk-other HPV Pap test samples, 21 genotypes of HPV were noted; the most common were 53 (n=6), 51 (n=6), and 59 (n=5).

This study developed risk assessments for various procedures performed at our specialized referral center based on the frequency of epinephrine use during these procedures. <b>Methods:</b> During a 5.5-year period, 5 allergists referred patients to a monthly high-risk procedure clinic (total of 66 clinic days). We conducted a retrospective medical records review from 2016 to 2021 to assess the types of procedures performed, instances of procedure termination, and use of epinephrine. <b>Results:</b> A total of 596 procedures were performed: 305 food challenges, 103 aeroallergen immunotherapy rush inductions, 75 drug challenges, 66 ultrarush inductions of venom immunotherapy, 12 drug desensitizations, 14 vaccine challenges (11 COVID-19 [coronavirus disease 2019], 2 influenza, 1 Tdap [tetanus, diphtheria, and pertussis]), and 21 miscellaneous nonvaccine challenges. Most procedures (n=551, 92.4%) were completed; 45 procedures (7.6%) were aborted early because of patient, parent, or physician requests. Reasons included the child not wanting to eat the food, the patient developing a headache, and other factors. Fifty-one of the 596 procedures (8.6%) required epinephrine administration: 32/305 (10.5%) for food challenges, 12/103 (11.7%) for aeroallergen immunotherapy rush inductions, 2/75 (2.7%) for drug challenges, 2/66 (3.0%) for ultrarush inductions of venom immunotherapy, 3/12 (25.0%) for drug desensitizations, and 0/35 (0%) for other challenges. Two patients required emergency department transfers, with no instances resulting in hospitalization or patient mortality. <b>Conclusion:</b> These data identify risks associated with diverse procedures conducted in allergy clinics. While 8.6% of cases required epinephrine, the majority of reactions were manageable within the clinic setting. These findings underscore the allergist's role in performing procedures with potential anaphylactic outcomes and managing anaphylaxis when it occurs in the clinic setting.
