“…So are those dealing with the structure–reactivity relationships operating in these oxidations 8, 9. But reports on comparison of the rates and mechanisms of oxidations of a substrate by these reagents are a few; diphenyl sulfide in glacial acetic acid 10, diethyl sulfide 11, benzyl alcohol 12, 2‐propanol 13, and 1‐pentanol 14 in aqueous acetic acid individually exhibit identical kinetic behavior on oxidation with dichromates and halochromates of heterocyclic bases. Here, for the first time, we compare the reaction constants of the oxidations by dichromates, fluorochromates, chlorochromates, and bromochromate of heterocyclic bases; primary aliphatic alcohols have been chosen for the study, as the oxidation mechanism has been elucidated recently 14.…”

Background Recent consensus statements on the diagnosis of chronic rhinosinusitis (CRS) now require endoscopic or radiographic evidence of paranasal sinus inflammation. The timing of point‐of‐care (POC) computed tomography (CT) scan in the workup of these patients remains to be elucidated, particularly when endoscopy is negative. The objective of this research was to prospectively evaluate 2 algorithms for the initial management of patients with symptoms of CRS who manifest a normal nasal endoscopic examination. Methods A total of 40 such patients were randomized to 1 of 2 pathways: POC‐CT at the initial visit followed by medical therapy based upon CT results (pre‐CT group; n = 20), or empiric medical therapy (EMT) followed by POC posttreatment CT if symptoms persisted (EMT group; n = 20). Results The 2 groups were demographically and symptomatically similar with regard to 2003 Task Force major criteria. Otolaryngology follow‐up was recommended in 11 of 20 pre‐CT patients, all of whom (100%) returned. In contrast, only 10 of 20 EMT patients (50%) followed up as instructed (p < 0.05). Radiographic confirmation of CRS was found in 8 of 20 pre‐CT patients, and only 2 of 9 patients after EMT (p = 0.61). EMT patients received more antibiotic prescriptions (relative ratio [RR], 2.50; 95% CI, 1.46–4.27), while pre‐CT patients received more CT scans (RR, 2.22; 95% CI, 1.37–3.61). Overall prescriptions costs were similar to the EMT group ($253 vs $218; p = 0.37) and the overall number of otolaryngology visits was similar. Conclusion In patients with symptoms of CRS but negative endoscopy, POC at initial presentation results in substantially less unnecessary antibiotic prescriptions and significantly greater compliance with otolaryngology care but does result in a higher utilization of radiographic imaging. © 2011 ARS‐AAOA, LLC.
