[Chronic myeloid leukemia--a rare cause of labyrinth apoplexy].

Background: Cochleovestibular lesions in patients with acute myeloid leukemia or the blastic phase of chronic myeloid leukemia are usually due to leukemic infiltration, infection or hemorrhage. In contrast, the most likely cause of cochleovestibular lesions in the chronic phase of the chronic myeloid leukemia seems to be disturbed microvascular perfusion and vascular occlusion.

Case Report: A 45-year old patient with a chronic myeloid leukemia presented with the sudden onset of profound deafness in his right ear combined with a total loss of vestibular function on the same side.

Value of computed tomography in patients with persistent vertigo after stapes surgery.

Rationale And Objectives: The value of computed tomography was evaluated in 14 patients with persistent vertigo after otosclerosis operation.

Methods: High-resolution computed tomography was performed with 1-mm slice thickness and table feed in the axial and coronal planes.

Results: Computed tomography scans showed in 13 case findings that related to symptoms.

[Diagnosis in persistent vertigo after stapes surgery].

One hundred sixty-two otosclerotic patients who underwent a stapedotomy between October 1991 and April 1994 were examined after experiencing postoperative vertigo. Twenty-eight complained of dizziness. In sixteen patients, we observed vertigo and nystagmus only within the first six postoperative days; in these cases, special treatment was not necessary.

[The value of computed tomography in persistent balance disorders following the use of stapes prostheses].

10 of 150 patients had persistent vertigo after implantation of stapes prostheses. These patients were evaluated by high-resolution CT in the axial and coronal plane. Scans showed in all cases findings which related to the symptoms.

[Changes in vegetative parameters during and after normobaric hypoxic hypoxia in newborn rabbits].

68 awake spontaneously breathing newborn rabbits were investigated in five series; 43 animals were exposed to a hypoxic atmosphere (FiO2 = 0.05) for 3 h during the 1st day of life. Heart rate, rectal temperature and intracranial pressure were recorded.

A follow-up study of perinatally hypoxic rabbits.

Rabbits, surviving a severe 3-hours-lasting hypoxia (FiO2 = 0.05) during the 1st day of life, grew up together with their littermates. In animals aged 10 and 20 days, respectively, the vestibular induced tonic eye deviations were investigated during tilting around the three orthogonal body axes.
