Levofloxacin-induced-neurological adverse events such as convulsion, involuntary movement (tremor, myoclonus and chorea-like) and visual hallucination in two elderly patients are reported. A 67-year-old man with minor alcoholism and a past-history of gastrectomy and cholecystectomy was given 300 mg/day of oral levofloxacin and fulfenamic acid for an upper respiratory infection. On the 4th day, he reported gradual exacerbation of hand tremor which resembled chorea-like involuntary movement and gait disturbance. He also experienced visual hallucinations. On the 7th day, he suffered generalized convulsions and was admitted. Serum concentration of levofloxacin at this time (3 hours after last administration of a 100 mg tablet of levofloxacin) was 3.6 micrograms/ml. Cessation of the agents promoted complete recovery of these neurological adverse effects within a week. Another 85-year-old man with chronic bronchitis and slight renal impairment received long term administration of 200 mg/day of levofloxacin. On the 68th day of administration, gradual exacerbation of gait disturbance, dysarthria and chorea-like involuntary movement occurred. On the day of admission, 76 days after the start of administration, the serum level of levofloxacin was 2.55 micrograms/ml and that of spinal fluid was 1.12 micrograms/ml (3 hours after the last administration of a 100 mg tablet of levofloxacin). Cessation of the agents promoted complete recovery of these neurological adverse effects within the next two weeks. Both patients had no apparent neurological disorders except age-related brain atrophy. Age-related renal and brain impairment might have contributed to the neurological adverse effects of levofloxacin.

Studies of late stages of Parkinson's disease (LS-PD) are limited. To provide an adequate health plan for patients in these most advanced stages, accurate information on their clinical condition is necessary. We characterize clinical features and medication use of LS-PD. A cross-sectional study of LS-PD stage 4 or 5 of Hoehn and Yahr during on states is presented in this paper. Demographics, clinical features and medication data were obtained using a structured questionnaire and physical examination. Patients were asked to grade the perceived impact of symptoms on their health status. Fifty patients (mean age 74.1 years and mean disease duration 17.9 years) were studied. Severe akinetic symmetric parkinsonism was present in most, with negligible rigidity and tremor, and most patients were wheelchair-bound. Severe postural instability and freezing of gait, causing frequent falls and fractures, and prominent dysarthria and dysphagia dominated the motor syndrome. Levodopa remained effective in most patients in relieving motor symptoms including tremor. Motor fluctuations and dyskinesias were present in 78 and 62% of patients, respectively, but were not perceived as disabling. All had neuropsychiatric and dysautonomic symptoms. Visual hallucinations were present in 44%, depression in 62% and dementia in 50%. Lack of tremor (p < 0.01) and absence of depression (p < 0.01) were independently associated with dementia (R(2) = 45%). Symptoms causing greatest impact on perceived health status were falls, gait unsteadiness, urinary dysfunction and sweats. Motor and non-motor non-levodopa responsive problems were frequent and the main cause of disability. Fluctuations and dyskinesias were frequent though not disabling. Dementia is not unavoidable in these very late stages.
