Alpha-synuclein pathology in the spinal cords of neurologically asymptomatic aged individuals.

The authors assessed the frequency of spinal cord alpha-synuclein pathology in neurologically asymptomatic individuals older than 60 years of age (N = 106). Using alpha-synuclein immunohistochemistry, nine cases (8%) had incidental Lewy neurites in the intermediolateral column and at least some alpha-synuclein pathology in the dorsal motor nucleus of the vagus, locus ceruleus, and central raphe nucleus. Sparse alpha-synuclein pathology was also detected in the substantia nigra, basal forebrain, amygdala, or cortex in all but two cases.

Features associated with the development of hallucinations in Parkinson's disease.

OBJECTIVE: To identify features related to the development of hallucinations in Parkinson's disease (PD). MATERIALS AND METHODS: Seventy PD patients with hallucinations (group 1) and 60 PD patients without hallucinations (group 2) were evaluated for disease severity, presence of motor complications, rapid eye movement (REM) behavior disorder (RBD), and antiparkinsonian drug profile. The ages at the emergence of hallucinations and duration of disease in group 1 were matched with the ages at the last visit of those in group 2. RESULTS: Disease severity and presence of motor complications were similar in both groups. RBD was more frequently encountered among hallucinators than among non-hallucinators (P = 0.007). The mean duration and daily doses of levodopa and other dopaminergic drugs did not differ in both groups; however, the usage of anticholinergics and amantadine were significantly more frequent in group 2, unexpectedly. CONCLUSIONS: The presence of RBD was significantly more common in hallucinators; however, severity of PD, duration and daily doses of dopaminergic drugs were not associated with the emergence of hallucinations.

Central nervous system infection due to Penicillium chrysogenum.

Penicillium chrysogenum was isolated from three subsequent cerebrospinal fluid (CSF) specimens of a 73-year-old male patient without immunological compromise. The isolated was tested against five antifungal agents according to the NCCLS M38-P macrodilution method. MICs were determined as follows: amphotericin B (AMB), 2 microg ml(-1); fluconazole (FLZ), 8 microg ml(-1); itraconazole (ITZ), 1 microg ml(-1); flucytosine (5FC), 0.125 microg ml(-1); and terbinafine (TRB), 0.06 microg ml(-1). The patient has been cured with FLZ.

Lewy bodies are not increased in progressive supranuclear palsy compared with normal controls.

OBJECTIVE: To determine the frequency of Lewy bodies (LB) in progressive supranuclear palsy (PSP). BACKGROUND: LB are characteristic of PD, but are also found in normal controls and in other neurodegenerative diseases, especially AD. METHOD: The authors evaluated the brains of 72 consecutive cases of pathologically confirmed PSP and 98 normal controls, ranging in age from 60 to 100 years, with immunohistochemistry for alpha-synuclein. RESULTS: LB and Lewy neurites were found in 13 cases of PSP, with the most numerous LB and Lewy neurites in the basal forebrain and amygdala; most cases also had LB in the substantia nigra. The frequency of LB in the substantia nigra (12%) was comparable to the frequency of LB in controls (9%). CONCLUSIONS: In contrast to increased frequency of LB in AD, there is no apparent interaction between LB and the tau pathology in PSP.

Extrapyramidal type rigidity in rheumatoid arthritis.

OBJECTIVES: We had noted cogwheel rigidity in a number of patients with rheumatoid arthritis (RA). Based on this finding, we aimed to investigate formally the presence of rigidity and cogwheeling in RA patients. Our secondary aim was to survey the co-existence of RA and Parkinson's disease (PD). METHODS: A total of 87 consecutive patients with a diagnosis of RA, 78 patients with PD and 67 otherwise healthy patients attending a dedicated headache clinic participated in the study. RESULTS: Rigidity was observed in 24% of RA, 60% of PD and 2% of headache patients. The frequency among the RA patients was significantly higher compared to that of patients with headache (chi 2 = 15.2; P = 0.00009). The frequency of PD among the RA patients was 2/87 (2.3%), while the frequency of RA among the PD patients was 6/78 (7.7%). CONCLUSION: Rigidity can be observed in approximately a quarter of patients with RA.

Posthemiplegic focal limb dystonia: a report of two cases.

Posthemiplegic focal limb or hemidystonias are rare movement disorders usually due to vascular lesions of the contralateral basal ganglia. The pathogenesis of posthemiplegic dystonia is unknown and its management is usually difficult. In this paper, we report two patients who suffered from a single limb dystonia and hemidystonia, respectively. In the latter patient, hemidystonia developed due to an ischaemic cerebrovascular accident 2 or 3 months after the recovery of hemiplegia. Computed tomography and magnetic resonance imaging scans showed evidence of contralateral putamen and thalamus infarcts.
