Hyperbaric oxygen as salvage treatment for idiopathic sudden sensorineural hearing loss.

OBJECTIVE: To investigate the efficacy of hyperbaric oxygen therapy as a salvage treatment for patients with sudden sensorineural hearing loss (SSHL). MATERIALS AND METHODS: Fifteen patients affected by sudden hearing loss and treated with hyperbaric oxygen after steroid and vasodilator therapy failed constituted the study group. A control group of 30 patients who were treated with steroids and vasodilator alone was also included. Hyperbaric oxygen was administered once daily for 15 sessions at a constant pressure of 2.2 atmospheres. Pure-tone hearing thresholds were obtained for both groups before and after each treatment and frequency-specific thresholds 3 months after the end of hyperbaric oxygen therapy. RESULTS: Salvage hyperbaric oxygen therapy was performed with a mean delay of 24 days from the onset of SSHL. The overall rate of hearing improvement was higher in the study group (7/15 cases, 46.6%) compared with the control group (4/30 cases, 13.3%). The mean pure-tone hearing average thresholds after salvage treatment in the study group was 53.4 dB HL (mean gain, 12.1 dB HL), which was significantly lower than that in the control group of 67.9 dB HL (mean gain, 2.7 dB HL). Hearing recovery was found to be better at low frequencies (250-500 Hz). CONCLUSION: Hyperbaric oxygen therapy should be suggested to all patients for whom initial conventional medical treatment for SSHL has failed.

Effectiveness of home-centered care through telemedicine applications for overweight and obese patients: a randomized controlled trial.

OBJECTIVE: To determine if home-centered monitoring through telemedicine has an impact on clinical characteristics, metabolic profile and quality of life in overweight and obese patients. DESIGN: Randomized controlled trial, 6-month duration. SETTING: Tertiary care academic hospital. SUBJECTS: A total of 122 patients were eligible to participate as they met the inclusion criteria of increased body mass index (BMI>25 kg/m(2)), age>18 and <70 y and ability to operate electronic microdevices. INTERVENTIONS: All patients in the control group (n=77) received standard hospital care. Patients in the intervention group (n=45), additionally, measured three times a week, for 6 months, their blood pressure and body weight and transmitted them to an automated call center. These values were not shared with the patients' physician or dietician. MAIN OUTCOME MEASURES: Clinical (body weight, BMI, blood pressure), laboratory (fasting plasma glucose, triglycerides, HDL-cholesterol, total cholesterol) and quality of life parameters (SF-36((R)), Visual Analog Scale of European Quality-5 Dimensions, Obesity Assessment Survey). Data were analyzed in an intention-to-treat-way (last observation carried forward). RESULTS: Drop-out rate was similar in the control and intervention groups: 12 vs 11 percent, respectively, P=NS. There were no significant differences at baseline between intervention and control groups in all main outcome parameters. There were significant decreases for patients in the intervention group in body weight (from 101.6+/-22.4 to 89.2+/-14.7 kg, P=0.002, P=0.05 vs controls at 6 months), total cholesterol (from 247.6+/-42.0 to 220.7+/-42.6 mg/dl, P=0.002, P=0.05 vs controls at 6 months) and triglycerides (from 148.4+/-35.0 to 122.3+/-31.4 mg/dl, P=0.001, P=0.01 vs controls at 6 months). Intervention group patients made a total of 1997 phone contacts. The number of phone contacts was correlated positively with Social Functioning (SF), Vitality (VT) and Mental Health (MH) scores of SF-36((R)) at baseline (r=0.48, r=0.41, r=0.41, respectively, P=0.05) but not with weight loss. CONCLUSIONS: Home-centered, intense treatment through the use of telemedicine can be effective in improving short-term obesity outcomes.
