Clinical features and treatment with botulinum toxin in blepharospasm: a 17-year experience.

Objective: It was to analyze clinical aspects of patients with blepharospasm, including outcomes of botulinum toxin treatment. Additionally, clinical characteristics of isolated blepharospasm were compared to those of blepharospasm plus other movement disorders.

Methods: Clinical data recorded during 17 years were reviewed.

Neurosarcoidosis: guidance for the general neurologist.

Neurosarcoidosis (NS) more commonly occurs in the setting of systemic disease. The diagnosis is based on a clinical history suggestive of NS, presence of noncaseating granulomas, and supportive evidence of sarcoid pathology, laboratory, and imaging studies. NS could involve any part of the nervous system and often demands high doses of steroids for symptom control.

Cognitive impairment in multiple system atrophy: Changing concepts.

Multiple system atrophy (MSA) is characterized by a variable combination of cerebellar ataxia, parkinsonism and pyramidal signs associated with autonomic failure. Classically, cognitive impairment was not considered a clinical feature of MSA and dementia was pointed out as an exclusion diagnostic criteria. Based on comprehensive neuropsychological assessment, cognitive impairment was found to be a frequent feature in MSA, and clinically-defined dementia is now reported in 14-16% of cases.

Gradenigo's Syndrome: Beyond the Classical Triad of Diplopia, Facial Pain and Otorrhea.

We report a case of a non-Hodgkin's lymphoma in a young woman presenting with an abdominal mass and an unusual instance of cranial nerve palsies mimicking Gradenigo's syndrome. This condition is characterized by a triad of otorrhea, facial pain and diplopia, related to otitis media in the pre-antibiotic era. Incomplete and atypical clinical features of Gradenigo's syndrome have been described and noninfectious causes may mimic this condition.

Long-term effect of Helicobacter pylori eradication on plasma homocysteine in elderly patients with cobalamin deficiency.

Background: Helicobacter pylori gastritis may lead to impairment of the production of pepsinogen and acid, which are essential to cobalamin absorption. In turn, cobalamin deficiency leads to hyperhomocysteinaemia, a risk factor for cardio and cerebrovascular diseases.

Aim: To evaluate the effect of H pylori eradication on plasma homocysteine levels in elderly patients.
