Quantitative assessment of finger-tapping performance in patients with parkinson's disease [Parkinson hastalarında parmakvuru performansının kantitatif degerlendirilmesi özet]

Objective: The objective, quantitative assessment of patients with Parkinson's disease (PD) is essential for both the diagnosis and follow-up. To be of value in clinical trials and daily clinical practice, the method should be simple and easy, with minimal inter-rater observer variation. The finger-tapping (FT) test is an informative measure of upper-extremity motor skills as a part of the neurological assessment of patients with PD. Therefore, this study evaluated the motor skills of patients with PD by using a computer-based system that quantifies FT performance. Method: Software to measure FT performance was assessed in 25 patients with PD and 25 normal controls by using two FT testing procedures: single FT (SFT) and alternate FT (AFT). Confounding factors that had the potential to affect the performance were considered, including age, sex, education, and cognition. Results: The SFT and AFT scores for the affected side of patients with PD were significantly lower than the corresponding scores for the dominant side of control subjects. In PD patients, our method appeared to be adequate for evaluating bradykinesia independent of age, cognition and education. AFT was a more sensitive tool for determining the disease severity. Conclusion: This method is a sensitive, practical, and objective tool for evaluating upperextremity motor skills in patients with PD. It also reflects the disease severity. We hope that this method might be useful in both daily practice and clinical studies

Clinical and cognitive profiles of patients with both Parkinson's disease and essential tremor

Although Parkinson's disease (PD) and essential tremor (ET) are distinct clinical disorders, their coexistence can sometimes cause diagnostic problems. In this study, we conducted detailed investigations of patients with both ET and PD (ET-PD) and compared their clinical and cognitive profiles with those of patients with only ET or only PD. This study examined three groups of patients: the first group had ET-PD concomitantly (n = 9); the second group had only ET (n = 9); the third group had only PD (n = 10). The groups were compared in terms of demographic characteristics, clinical features, and cognitive functions. With the exception of positive family histories, which were more common in ET-PD than in PD patients, we found no differences among the groups with respect to demographic characteristics (p = 0.044). PD-only patients had more akinetic-rigid type Parkinsonism (p = 0.016), and their levodopa response was better than that of ET-PD patients (p = 0.017). Patients with ET-PD obtained significantly lower scores than those with pure ET on several cognitive tests, suggesting a prominent frontal-type cognitive dysfunction. In conclusion ET-PD patients differed from PD patients, showing more frequent familial tremor histories and lower levodopa responsiveness. This patient population also demonstrated more severe cognitive impairments than pure-ET patients. This result suggests that ET-PD patients are a subset of ET patients with more widespread neurodegeneration, which may indicate the presence of a syndrome that includes overlap between ET and PD. © 2012 Belgian Neurological Society

An unusual case of neuro-Behçet's disease presenting with co-occurence of cerebral venous sinus thrombosis with basilar artery occlusion

Non-parenchymal neuro-Behçet disease generally affects cerebral venous sinuses, whereas intracranial intracerebral arterial involvement has been rarely reported. But co-involvement of both intracranial intracerebral artery and venous vascular systems in a patient at the same time has not been mentioned before. To the best of our knowledge, this case involving a 25-year-old male with a 7-year history of Behçet disease is the first reported of this type of involvement. He developed occlusion of the basilar artery together with thrombosis of the left sigmoid sinus, distal internal jugular vein, and straight sinus. He was successfully treated with a combination of high-dose steroid and cyclophosphamide. Cranial magnetic resonance angiography demonstrated the resolution of these abnormalities. © 2012 Springer-Verlag

Polyarteritis nodosa: lessons from 25 years of experience

Objective. Polyarteritis nodosa is a necrotising vasculitis of predominantly medium-sized vessels. The present study aimed to summarise the characteristics of PAN patients, and also analyse the trend of decreasing PAN frequency in the last 25 years
