Pulmonary Rehabilitation After Total Laryngectomy: A Multicenter Time-Series Clinical Trial Evaluating the Provox XtraHME in HME-Naïve Patients.

BACKGROUND: Both the immediate beneficial physiological changes in a laboratory setting and the long-term clinical outcomes of heat and moisture exchanger (HME) use are well described. So far, there has not been any research published that provides detailed insight in the pattern of changes in both respiratory function and patients' experiences with HMEs in the first weeks of use. METHODS: A multicenter time-series study design with a 2-week double baseline period. All patients used the XtraHME for 12 weeks afterward. Data were collected 2 weeks, 6 weeks, and 12 weeks after the start of HME use. RESULTS: Data of 30 patients were analyzed. Pulmonary symptoms decreased significantly during the 12 weeks of HME use. After 2 weeks, a significant decrease in daily coughs and daily forced expectorations was seen. The general quality of life showed a significant increase throughout the study. More general physical complaints also significantly decreased with HME use. Patient satisfaction with the HME was high. CONCLUSIONS: This study shows that there is a significant influence of the XtraHME on pulmonary status that can already be observed after 2 weeks of using the XtraHME and continues to improve further after 6 weeks of XtraHME use.

Oral versus short-term intratympanic prednisolone therapy for idiopathic sudden hearing loss.

OBJECTIVES: To assess the therapeutic effectiveness of an intratympanic (IT) steroid protocol compared to a systemic steroid protocol. METHODS: A total of 265 consecutive patients presenting unilateral idiopathic sudden sensorineural hearing loss were divided into 2 groups. One group comprised 131 patients enrolled between May 2009 and May 2010, and the other consisted of 134 patients enrolled between June 2010 and June 2011; a total of 48 patients were excluded among the 2 groups. The first group received oral prednisone for 8 days in tapering doses; the second group had IT prednisolone at a dose of 62.5 mg/ml once a day for 3 consecutive days. Audiological examinations were performed at study entry and 30 days after the beginning of therapy. Mean pure tone audiometry (PTA) of both groups and hearing outcomes following the criteria of Furuhashi et al. [Clin Otolaryngol 2002;27:458-463] and Siegel [Otolaryngol Clin North Am 1975;8:467-473] were investigated. RESULTS: The strong efficacy of steroid therapy was evident in both groups, observing both PTA and hearing threshold improvement. The evaluation of the hearing outcomes shows a significantly better result for the short-term IT protocol; this result is ascribable to two types of audiometric curves: down- and up-sloping. CONCLUSION: The results show a significant efficacy of both steroid therapeutic approaches. There was no significant difference in PTA improvement between the 2 study groups; the short-term IT protocol led to better results in the evaluation of the hearing outcomes (following the criteria of Siegel and Furuhashi et al.) for up- and down-sloping audiometric curves.

Sleep architecture variation in chronic tinnitus patients.

OBJECTIVES: The aim of the study was to evaluate the sleep architecture and its possible alterations in chronic tinnitus patients, and investigate any possible correlation between sleep architecture modifications and tinnitus perception, adaptation, and the degree of discomfort in these patients. DESIGN: In a prospective, case-control, nonrandomized study, 18 patients affected by chronic tinnitus were compared with a homogeneous control group consisting of 15 healthy subjects. The experimental group was enrolled at the Tinnitus ambulatory at Policlinico Umberto I Department of Sensory Organs, and the control group was composed of voluntary subjects. A full overnight polysomnography was performed on both groups. Tinnitus patients answered two questionnaires: the tinnitus handicap inventory (THI) and a questionnaire concerning their subjective sleep quality, tinnitus intensity before bedtime, tinnitus intensity at remembered nocturnal wake-up periods, and tinnitus intensity at morning wake-up. Controls completed only the sleep quality questionnaire. RESULTS: All tinnitus patients had a statistically significant alteration in sleep stages. Average percentage of stage 1 + stage 2 was 85.4% ± 6.3, whereas, in the control group, the average percentage of stage 1 + stage 2 was 54.9 ± 11.2 (p < 0.001). Stages 3 and 4 and rapid eye movement (REM) sleep was lacking in all tinnitus patients with an average percentage of 6.4 ± 4.9 of REM sleep, and 6.4 ± 4.9 of stages 3 + 4. The control group showed an average percentage of 21.5 ± 3.6 of REM sleep and 21.5 ± 3.6 of stages 3 + 4 (p < 0.001). No correlation was found between the decrease of REM and the increase of the THI score in the tinnitus group (r = 0.04). However, a mild correlation was found between the increase of light sleep (stage 1 + stage 2) and the THI score reported by the tinnitus group. Therefore, patients with light sleep report a higher THI score (r = 0.4). CONCLUSIONS: The significant alteration of sleep parameters assessed in tinnitus patients underlines the necessity to consider an adequate therapy that could improve patients' sleep quality and also opens avenues for further investigations.
