[Study on 242 inpatients reporting vertigo and dizziness].
We studied 242 inpatients--men (34%) and women (66%) reporting vertigo and dizziness while hospitalized at Hakodate Municipal Hospital from July 1999 to June 2002. Adults over 65 years old accounted for 47.3% of all subjects. Reports of symptoms tended to increase in March, August, and December. Cases were classified into 4 groups: 1) peripheral disorders (35.7%), 2) central disorders (7.9%), 3) disorders of other origins (8.3%), and 4) disorders of unknown origin (47.1%). Group 1) involved vestibular neuritis (10.1% of all cases), Meniere diseases (12.4%), benign paroxysmal positional vertigo (BPPV) (5.8%), and sudden deafness with vertigo (5.8%). Patients with vestibular neuritis--25 subjects including men (68%) and women (32%)--tended to be admitted mainly in July. Vestibular compensation in 15 patients with vestibular neuritis was studied using the platform stabilometry. The total length of a locus and the area of surroundings with open eyes decreased significantly (p < 0.05) as the condition of patients improved. In conclusion, many subjects reporting vertigo and dizziness had vestibular neuritis and few had BPPV. We found platform stabilometry to be useful in estimation of improvement in patients with vestibular neuritis.
