Auditory brain stem evoked potentials in patients with leprosy.
Nineteen, randomly selected male patients with lepromatous leprosy were evaluated electrophysiologically. All of these patients had long-standing disease and were treated with dapsone alone. There were statistically significant differences between the values obtained in this group of leprosy patients compared to 20 age-matched controls in auditory brain stem evoked potentials (ABEP). The findings are consistent with a pathologic process located mainly between the cochlear nucleus and the lateral lemniscus in the auditory brain stem pathways. It should be emphasized that our patients had long-standing disease which was treated with dapsone. ABEP could very well be different in leprosy patients diagnosed early and treated for relatively short periods with multidrug therapy. Brain stem evoked response audiometry may be useful for evaluating the possibility of brain stem involvement in leprosy.

Hearing loss in insulin-dependent diabetes mellitus.
The purpose of this study was to examine the relationship between diabetes mellitus and hearing loss which is still controversial. Pure tone audiometry was performed in 75 patients with insulin-dependent diabetes mellitus, aged between 14 and 60 years (45 males and 30 females; average age 45.3 years), and in 40 randomly selected sex- and age-matched non-diabetic control subjects, using an Interacoustics Clinical Computer Audiometer Model AC5. The mean duration of diabetes in the study group was 15 +/- 7 years. Complications such as retinopathy, nephropathy, and neuropathy had developed in 64% of the diabetics. Statistical analyses showed that the hearing of the diabetic patients was significantly worse than control subjects. Complications were found to have a significant effect on sensorineural hearing loss in diabetics. The influence of duration of diabetes was noticed on hearing threshold at mid and high frequencies, especially after the first decade of the disease.

Doppler sonography of vertebral arteries in patients with tinnitus.
The accuracy and the reliability of extracranial vertebral artery Doppler flow for the detection of the possible cause of the tinnitus was studied prospectively and Doppler findings were compared with controls. Vertebral artery measurements have been made in 28 patients (56 vertebral arteries) with tinnitus and 12 sex- and age-matched controls. Maximal flow velocity and mean flow velocity were measured and total vertebral artery flow was calculated by adding flows from the right and left sides. When compared with each other and controls, there was significant difference with respect to mean flow velocities of the right and left vertebral arteries in the patients with tinnitus (p < or = 0.05), and also total mean flow velocity between patients with tinnitus and controls (p < or = 0.05). It has been concluded that Doppler sonography gave useful information on the vertebral artery flow in patients with tinnitus.

Doppler sonography of vertebral arteries and audiovestibular system investigation in leprosy.
Thirty-six patients with leprosy and 12 sex- and age-matched controls were investigated for disorders of the audiovestibular system, and vertebral artery measurements were calculated using a color Doppler ultrasound technique. Sensorineural hearing loss found to be of cochlear origin was detected in 8 of the leprosy patients. Maximal flow velocity and mean flow velocity were measured, and the total vertebral artery flow was calculated by adding flows from the right and left sides. There was a significant reduction in the total maximal peak flow velocity of the vertebral artery of the lepromatous patients compared to the controls. Doppler sonography of the vertebral artery gave useful information about some pathology seen in lepromatous patients.

Tuberculous tonsillitis.
The epidemiology of tuberculosis has changed recently with an increasing incidence of unusual presentations. A case of tuberculous tonsillitis, which is a rare condition, is presented in this report. The manifestations of this entity are tonsillar hypertrophy and painful ulceration. Final diagnosis of tuberculous tonsillitis is usually made after histopathologic examination of tonsillectomy material. Cultures should be obtained from the tissue specimens, and acid-fast bacilli must be investigated to confirm the diagnosis. Systemic signs of tuberculosis may not be seen in this clinical form. These features may confuse tuberculous tonsillitis with malignancies. In this article, general information and literature about tuberculous tonsillitis are reviewed, and a case of tuberculous tonsillitis is reported to draw attention to this rare clinical form of tuberculosis.

Audiovestibular system, fifth and seventh cranial nerve involvement in leprosy.
Thirty-nine patients with leprosy and fifteen sex- and age-matched controls were investigated for disorders of the fifth and seventh cranial nerves and that of the audiovestibular system. Sensorineural hearing loss found to be of cochlear origin was detected in eight (22%) of the patients with leprosy compared to none in the control group (p > 0.05). Vestibular dysfunction was noted in four patients (11.1%) compared to none in the control group (p < or = 0.05). Two cases were found to have fifth nerve involvement and one (2.8%) had seventh nerve involvement. None in the control group had fifth or seventh nerve deficit.
