ABSTRACT

The purposes of this study were to validate the use of a single standard question for the rapid screening of restless legs syndrome (RLS) and to analyze the eventual effects of the presence of RLS on self-assessed daytime sleepiness, global clinical severity and cognitive functioning. We evaluated a group of 521 consecutive patients who accessed our neurology clinic for different reasons. Beside the answer to the single question and age, sex, and clinical diagnosis, the following items were collected from all patients and normal controls: the four criteria for RLS, the Epworth Sleepiness Scale (ESS), the Clinical Global Impression of Severity (CGI-S), and the Mini-Mental State evaluation. RLS was found in 112 patients (70 idiopathic). The single question had 100% sensitivity and 96.8% specificity for the diagnosis of RLS. ESS and CGI-S were significantly higher in both RLS patient groups than in normal controls. RLS severity was significantly higher in idiopathic than in associated/symptomatic RLS patients. RLS can be screened with high sensitivity and good reliability in large patient groups by means of the single question; however, the final diagnosis should always be confirmed by the diagnostic features of RLS and accompanied by a careful search for comorbid conditions.

ABSTRACT

We describe kinematics, kinetics and electromyographic patterns of a patient with spinal myoclonus of the left lower limb, during walking. Gait analysis was performed when the patient was OFF and ON his treatment with antiepileptic drugs. When OFF, we mainly observed clonic bursts and out-of-phase activations of m. tibialis anterior and m. rectus femoris, with increased hip flexion, reduction of knee flexion during swing and excessive ankle dorsal flexion. Furthermore, large oscillations of knee moment of force and power during stance phase were also observed. These abnormal patterns markedly recovered when ON drugs.

ABSTRACT

Several studies have demonstrated the importance of hypercholesterolemia as a cardiovascular risk factor and a direct correlation between the reduction in cholesterolemia and the reduction in cardiovascular mortality in populations younger than 65 years. This correlation is controversial in the elderly and, particularly, in the oldest old. The aim of our study was to evaluate the total cholesterol in the oldest old and to assess the eventual presence of correlation between total cholesterol levels and mortality in a group of nondemented oldest old. A subsample of 40 subjects was extracted from the 103 subjects aged over 84 years living in Troina, a rural village in Sicily. We excluded all subjects under therapy with lipid-lowering drugs, demented, with malnutrition or affected by acute or chronic diseases which might cause death in the short term. At the end, 23 subjects (15 males and 8 females) were included in the study. After 2 years, mortality data of all subjects included in the study were obtained from official registers. The statistical analysis was performed by means of the X(2) test. In all subjects the mean of total cholesterol was of 182+/-32 mg/dl (mean+/-SD) and the body mass index was above 20; 17 subjects were in the normal range, 3 were moderately over-weighed and 3 were severely over-weighed. Overall, mortality rate after 2 years was 30% (7 subjects, 4 males and 3 females). We evaluated the relationship between mortality and 4 factors: sex, age, body mass index (BMI) and serum total cholesterol. Mortality was significantly correlated (p<0.002) only with a low level of total serum cholesterol

ABSTRACT

Senescence is accompanied by an important increase in prevalence and incidence of ischemic stroke. The plasma level of fibrinogen tends to increase with age in the elderly similarly to the prevalence of stroke. The aim of our study was to evaluate the age-related increase in fibrinogen plasma level in the elderly and to assess the presence of eventual differences between normal subjects and patients with previous ischemic stroke associated with precerebral atherosclerosis. Eighty inpatients (41 males and 39 females), consecutively admitted to our Geriatric Unit, were included to this study. The patient group was formed 32 subjects (20 males and 12 females) aged 50-79 years, suffering from cerebrovascular disease with one or several previous ischemic stroke episodes, having occurred at least 1 year earlier. The control group consisted of 48 normal subjects (21 males and 27 females) aged 50-79 years. Both control and patient groups were subdivided into three subgroups, according to their age: Group 1 (50-59 years), Group 2 (60-69 years)and Group 3 (70-79 years). The statistical comparison was carried out by means of the Mann-Whithney nonparametric test. In normal controls, a mild age effect is evident because only Group 3 shows fibrinogen levels significantly higher than those of Group 1. On the contrary, in patients with ischemic stroke, an age effect is already evident between Group 2 and Group 1; of course, also the comparison between patient Group 3 and Group I shows a statistically significant difference. Moreover, the levels of fibrinogen were significantly increased in patient Group 2 and 3 when compared to those of their respective age-matched controls. Our data are in agreement with those already available in the literature and demonstrate that fibrinogen in normal aging changes with age and shows a 19 %increase between age Group 1 and Group 3. Patients with ischemic stroke show an earlier and more evident age-related increase in fibrinogen than normal controls. Even if it is not possible to know, if the increase in fibrinogen is a consequence or not of the ischemic stroke, we can affirm that certainly the increased levels of fibrinogen should be considered as an important risk factor in the elderly for cerebrovascular disease and deserve treatment.

ABSTRACT

Lyme disease, or borreliosis, is a zoonosis transmitted by Borrelia burgdorferi which also involves the central nervous system (CNS), in 15% of affected individuals, with the occurrence of aseptic meningitis, fluctuating meningoencephalitis, or neuropathy of cranial and peripheral nerves. Encephalopathy with white matter lesions revealed by magnetic resonance imaging (MRI) scans in late, persistent stages of Lyme disease has been described. In this report, we describe a patient with few clinical manifestations involving exclusively the eighth cranial nerve, monolaterally and diffuse bilateral alterations of the white matter, particularly in the subcortical periventricular regions at cerebral MRI. This single patient study shows that the search for antibodies against Borrelia burgdoferi should always be performed when we face a leukoencephalopathy of unknown origin. An isolated lesion of the eighth cranial nerve can be the only neurologic sign in patients with leukoencephalopathy complicating Lyme disease.
