The reliability and validity of the 3-m backward walk test in people with Parkinson's disease.

Background: People with Parkinson's disease (PwPD) lose the ability in backward walking which is an important part of mobility in daily life. The 3-m backward walk test (3MBWT) evaluates backward walking; however, its reliability and validity have not been examined in PwPD yet.

Aims: To examine (1) the test-retest reliability of the 3MBWT in PwPD; (2) the minimum detectable change in the 3MBWT times; (3) the concurrent and known-groups validity of the 3MBWT; and (4) the optimum cutoff time which best discriminates fallers from non-fallers with Parkinson's disease (PD).

Comparison of dual-task costs during different types of walking in people with Parkinson's disease: a controlled study.

Introduction: Many of the activities in daily living require different walking skills such as straight walking (SW), walking with turning (WwT), curved walking (CW) or backward walking (BW) in a dual-task condition. However, there is a lack of evidence regarding the dual task cost (DTC) during different types of walking. Therefore, this study was planned to compare the DTC during different types of walking in people with Parkinson's disease (PwPD) and healthy controls.

Among 60 patients (29 males, 48.

Homocysteine Levels in Parkinson's Disease: Is Entacapone Effective?

Plasma homocysteine (Hcy) levels may increase in levodopa-treated patients with Parkinson's disease (PD) as a consequence of levodopa methylation via catechol-O-methyltransferase (COMT). Results from previous studies that assessed the effect of COMT inhibitors on levodopa-induced hyperhomocysteinemia are conflicting. We aimed to evaluate the effects of levodopa and entacapone on plasma Hcy levels.

Tear levels of tumor necrosis factor-alpha in patients with Parkinson's disease.

Neuroinflammatory events mediated by the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-α) cause progressive neurodegeneration in dopaminergic neurons, and play an important role in the pathogenesis of Parkinson's disease (PD). The purpose of this study was to determine TNF-α levels in tear samples obtained from patients with PD and to analyze the relationship between TNF-α values and PD characteristics. Eighteen patients with PD and 17 healthy control subjects were included in the study.

To investigate the effect of serum Ca on clinical features of ischemic stroke; the association of serum Ca levels measured in the first 24 hours with the severity of clinical symptoms on admission and short-term prognosis is evaluated.

A case report about CADASlL: mutation in the NOTCH 3 receptor.

CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is a rare autosomal dominant genetic disease characterized with recurrent stroke, migrainous headache, cognitive deficits, and psychiatric symptoms associated with mutations in the NOTCH 3 gene on chromosome 19. Here, we report a case of CADASIL who presented with migrainous headache, behavioral disorder, and familial history of stroke and the diagnosis was established by the findings of head magnetic resonance images revealing characteristic white matter lesions and a mutation in the NOTCH 3 gene.

Abdominal wall haematoma in cardioembolic stroke due to enoxaparine therapy: a report of two cases.

Abdominal wall haematomas are uncommon and often misdiagnosed entities. Most of the time the haematoma is produced by rupture of the epigastric vessels, deep circumflex iliac artery or tear in the rectus or lateral oblique muscle. Predisposing factors such as arteriosclerosis of vessels, old age, straining while urinating and coughing and use of anticoagulant agents make bleeding more likely.
