ABSTRACT: To evaluate changes in perceptual and several acoustic parameters of voice in patients with Parkinson's disease (PD) and to find out any relation with these parameters and motor components of Unified Parkinson's Disease Rating Scale (UPDRS) in this patient group.
Twenty patients with PD (12 male and 8 female) were given objective and subjective voice tests and results were compared with those of 20 age- and sex-matched controls. Patient's perceptual voice analysis was assessed using GRBAS scale including Grade of Dysphonia, Roughness, Breathiness, Asthenia and Strain items. Measurements for objective voice analysis, acoustic assessment tests including frequency perturbation [jitter (jitt)%], intensity perturbation [shimmer (shim)%], noise to harmonic ratio (NHR), fundamental frequency (F0), variability of fundamental frequency (vF0), diadochokinetic rate (DDK) and maximum phonation time (MPT) were used. An assessment of disability caused by voice disorders was scored according to the Voice Handicap Index (VHI) by the patient. All subjects also underwent videolaryngostroboscopic (VLS) examination. Motor components of UPDRS and acoustic parameters of voice were investigated for any correlations.
Compared with controls, roughness (P = 0.15), breathiness (P = 0.004) and asthenia (P = 0.031) values of males and breathiness (P = 0.043) and asthenia (P = 0.023) values of females were higher in patients with PD. Mean VHI scores of patients with PD were higher for both male and female patients (P = 0.0001 for male, P = 0.002 for female). The mean values for MPT (P = 0.02) and DDK (P = 0.025) were shorter in patients with PD. Jitt%, shim% and mean F0 values were similar among the two groups. But mean vF0 values were significantly higher in male patients with PD (P = 0.05). On VLS examination, non-closure glottic pattern was found to be more frequent in the PD group.
Although it is well known that pathophysiological changes in PD affect the voice, the present study found only few significant correlations between motor component of UPDRS and voice parameters.

ABSTRACT: To determine and compare the therapeutic efficiency of ciprofloxacin hydrochloride and gentamicin sulfate in the treatment of chronic ear disease.
Prospective randomized study.
Academic tertiary medical center.
Consecutive referred sample of 44 patients with chronic suppurative otitis media randomized into two groups.
Ciprofloxacin hydrochloride (200 mg/mL) was administered to the first group (composed of 24 patients), while the second group (composed of 20 patients) received gentamicin sulfate (5 mg/mL) locally, five drops three times a day for 10 days.
In the ciprofloxacin group, 21 (88%) of the 24 patients with suppurative chronic otitis media were cured. On the other hand, only six (30%) of the patients in the gentamicin group were cured. The rest of the patients showed no clinical or bacteriological improvement.
To our knowledge, this is the first study to compare the efficiency of two topical otic preparations in the treatment of chronic ear disease. The results show that topical ciprofloxacin preparation is more efficacious and efficient than topical gentamicin for the treatment of chronic otitis media in the acute stage.

ABSTRACT: This study has been performed between December 1990-March 1991 in the Microsurgery laboratory of the Marmara University Hospital. Twelve healthy albino guinea pigs were used as a study group while the control group consists of three animals. The potentials for cholesteatoma formation of the squamous epithelium, namely the squamous epithelium of the posterior superior part of the external ear canal skin and normal skin, were investigated. Among 24 subjects who were implanted by canal skin, cholesteatoma was formed in 21 of them. Likewise, 19 of 24 animals implanted by normal skin came out with cholesteatoma formation. Between these two types of epithelium, there is no statistical difference in cholesteatoma formation (p > 0.5).
