RESUMEN

BACKGROUND: Because the principle behind functional endoscopic sinus surgery (FESS) recognizes the middle meatus as essential for the control of the disease, the effect of the operation in the distribution of drugs in the same area should be of similar importance. This study was designed to clarify whether nasal drug delivery is improved in patients after FESS. The study involved a prospective assessment within subject comparison. The subjects were 20 adult (>18 years old) patients on the waiting list for FESS. It was conducted within two teaching hospitals in the East of Scotland. METHODS: A novel method was used, positioning a neurosurgical patty in the middle meatus and assessing blue dye nasal spray absorption on a 4-point scale. RESULTS: A significant improvement was observed in the distribution of the indicator in the middle meatus postoperatively. Seventy percent of the patients showed improvement in the drug distribution after FESS. The median result for absorption score was 2 preoperatively (<50%) and 3 postoperatively (>50%). The difference was statistically significant (p<0.001). CONCLUSION: The distribution of nasal drugs is improved in the middle meatus after FESS. This can have important clinical applications that can benefit patients in otolaryngology as well as other disciplines.

RESUMEN

OBJECTIVE: To evaluate the management of patients with malignant tumors of the ear and temporal bone. DESIGN: Retrospective analysis of data. SETTING: Radcliffe Infirmary, Oxford, United Kingdom. PARTICIPANTS: Twenty-seven patients were classified into two groups according to the site of origin of the tumor: (1) superficial (17 tumors): tumors arising from the skin of the pinna, parotid, and temporomandibular joint area; (2) deep (10 tumors): tumors arising in the ear canal and temporal bone. MAIN OUTCOME MEASURES: Treatment modality, complications, recurrence rate, disease-free interval, and survival. RESULTS: The mean follow-up period was 25 months (0 to 60), and the median overall survival 46 months (0 to 102). Complications occurred in 6 patients (22%). The 3-year survival was 38% (95% confidence interval [CI], 19 to 58%), and the 5-year survival 19% (95% CI, 3 to 35%). CONCLUSIONS: There were insufficient data to demonstrate any difference in survival or disease-free interval related to the site of tumor origin (superficial versus deep tumors). There were independent differences in survival in favor of both performing parotidectomy and using postoperative radiotherapy, but neither reached significance at the 0.05 level.

RESUMEN

BACKGROUND: Peak nasal inspiratory flow (PNIF) measurements are used to evaluate nasal obstruction and as a surrogate for disease activity in allergic rhinitis and other nasal complaints. This measurement can give erroneous results when forced inspiration leads to nasal valve collapse. OBJECTIVE: To determine the effects of 2 different nasal stents (Sinuscone and Nozovent) on valve collapse and repeatability of PNIF measurements. METHODS: Repeated measurements of PNIF were obtained in 74 individuals with and without 2 different nasal stents: Sinuscone and Nozovent. RESULTS: The mean (95% confidence interval) improvement in PNIF was 1.7 L/min (-2.4 to 5.8 L/min; P = .42) with Nozovents and 25.4 L/min (11.4 to 39.4 L/min; P = .001) with Sinuscones. The PNIF coefficient of variation for repeatability was 11.6% without stents, 16.0% using Nozovents, and 10.4% using Sinuscones. CONCLUSIONS: Sinuscones, but not Nozovents, significantly improved PNIF. Repeatability of PNIF measurements was worse with Nozovents and only marginally improved with Sinuscones.

RESUMEN

BACKGROUND: Small airways inflammation is a recognized pathologic component of asthma, and it is postulated that the observed airway-wall remodeling in small airways could be due to uncontrolled inflammation in airways that are not penetrated by conventional inhaled corticosteroids. Thus, extrafine particle formulations of inhaled corticosteroids are of clinical interest. OBJECTIVE: To compare 2 extrafine solution hydrofluoroalkane-134a formulations of beclomethasone dipropionate (Beclate and Qvar). METHODS: Fifteen asthmatic patients (mean +/- SEM forced expiratory volume in 1 second [FEV1], 2.62 +/- 0.21 L; provocative concentration of methacholine causing a 20% decrease in FEV1 [PC20], 1.06 +/- 0.58) were randomized to completion in a placebo-controlled, double-blind, crossover manner to receive Beclate or Qvar at doses of 100 or 400 microg/d for 2 weeks, with a 1-week washout period before each randomized treatment. Methacholine hyperresponsiveness was the primary outcome measure. RESULTS: The 2 formulations were equivalent in terms of predefined equivalence limits of +/- 1 doubling dilution for PC20 at both doses: -0.25 (95% confidence interval [CI], -0.77 to 0.27) doubling dilution difference between the 100-microg doses and a 0.26 (95% CI, -0.29 to 0.82) doubling dilution difference between the 400-microg doses for the difference between Beclate and Qvar, respectively. Both formulations, at either dose, produced a statistically significant (P < .05) reduction in mean exhaled nitric oxide levels: 400 microg/d of Beclate, 14.1 ppb (95% CI, 5.6 to 22.6 ppb); and 400 microg/d of Qvar, 14.2 ppb (95% CI, 6.0 to 22.4 ppb). The higher doses produced a statistically significant (P < .05) reduction in early morning urinary cortisol-creatinine ratio (geometric mean fold suppression: Beclate, 1.48 [95% CI, 1.16 to 1.89]; and Qvar, 1.42 [95% CI, 1.12 to 1.79]). Both formulations significantly improved peak expiratory flow, FEV1, and forced expiratory flow between 25% and 75% of forced vital capacity at the higher doses (P < .05). CONCLUSIONS: Beclate and Qvar were equivalent for all primary and secondary outcome measures.

RESUMEN

Thirty-six persistent allergic rhinitis (PAR) sufferers were studied, to both compare and correlate 15 minute response to nasal xylometazoline (XYLO) with 28 day response to nasal mometasone furoate (MF). 0.1% XYLO (1 spray each nostril) response was measured on two occasions, then a randomised double blind cross-over comparison of MF (200 mcg daily) to placebo conducted. Outcomes were peak nasal inspiratoly flow (PNIF), nasal forced inspiratory volume in one second (nFIV1) and nasal blockage score (NBS) improvements. Thirty-one participants completed per protocol. Within subject standard deviation for percentage improvement to XYLO was 26.0 for PNIF and 25.2 for nFIV1. Median % improvement (95%CI) in PNIF for XYLO vs. MF was 20.0 (11.4 to 31.0) vs. 9.6 (3.2 to 15.8) and in nFIV1 was 17.8 (10.0 to 28.1) vs. 3.3 (-4.3 to 19.1). XYLO effects were greater than MF (p<0.05) for PNIF, nFIV1 and NBS. There was no significant correlation of MF to XYLO improvements in PNIF, nFIV1 or NBS. In conclusion, acute reversibility to XYLO showed poor repeatability and XYLO reversibility is not predictive of decongestant response to nasal corticosteroid. XYLO was a stronger decongestant than MF but rhinitis medicamentosa still precludes any preference for long term XYLO therapy at this time.
