[Summating potentials in the differential diagnosis of cochlear pathology].

Three groups of patients with Ménière's disease, sensorineural hearing loss caused by acoustic trauma, and healthy controls were examined by electrocochleography in order to establish the value of absolute summating potential (SP) amplitudes in the differential diagnosis of these entities. A statistically significant increase in absolute SP amplitudes was found in patients with Ménière's disease in comparison to patients with sensorineural hearing loss caused by acoustic trauma (p < 0.01). Besides that, there was also a statistically significant increase in absolute SP amplitude values in healthy persons, as compared to patients with sensorineural hearing loss caused by acoustic trauma (p < 0.05).

[Auditory evoked potentials in alcoholics].

In this paper, auditory brain stem potentials in the group of 26 alcoholics were studied and a significantly delayed latencies of the peaks II through V as compared to the healthy control subjects were found. In addition, a statistically significant prolongation of brain stem transmission time (BTT) in alcoholics was observed. The study also suggests the possibility of monitoring the level of pathohistological changes of the central auditory pathway caused by excessive alcohol consumption.

[Oncocytic lesions of the larynx].

Oncocytic lesions of the larynx are considered particularly rare. Different names for these lesions have been used as a result of various theories concerning their biologic nature which is still controversial. Most investigators interpret these lesions as oncocytic metaplasias of the mucous gland cells in the larynx connected with senile involution of the upper respiratory tract with or without hyperplasia rather than true neoplasias. They are benign lesions, comprising 0.5 to 1% of all laryngeal mucosal changes, with a tendency to multifocal involvement occurring in patients over 50 years of age. Surgical excision is the treatment of choice. A case is reported.

[Complications after prolonged intubation in patients with head trauma].

In this study, 72 patients with head injury, hospitalized in the Intensive Care Unit (ICU) were analyzed. All of them required prolonged intubation. Every patient was initially intubated. Thirty (41.7%) of them underwent tracheotomy and 56 (77.8%) demanded mechanical ventilation. The patients were divided into three groups with respect to their treatment: 1. Patients intubated up to five days--27 (37.5%); 2. Patients intubated more than five days--45 (62.5%); 3. Tracheotomized patients--30 (41.7%). Tracheotomy was done between the fifth and the twenty-sixth day following the intubation. Laryngotracheal complications occurred in 47% of the patients from the second group and 23% from the third group. The patients in the first group developed no complications. Pulmonary infections prevailed in the second group. We conclude that early postinjury tracheotomy is associated with a lesser incidence of complications than prolonged intubation in neurosurgical patients.
