Movement disorders secondary to long-term treatment with cyclosporine A.

OBJECTIVE: To analyze the prevalence, severity and functional interference of movement disorders (MD) secondary to chronic use of cyclosporine A (CsA). METHOD: We conducted a cross-sectional study of 60 patients (58.3% male) with mean age 23.1 (3-75) years, followed at the Bone Marrow Transplantation Service of the Hospital de Clínicas of the Federal University of Paraná, Brazil, taking CsA for at least six months. Our protocol included clinical data, assessment of functional interference of symptoms and neurological examination including observation and grading of MD. RESULTS: Eight (13.3%) subjects reported the presence of tremor at the moment of interview and 29 (48.3%) recalled this symptom at some point during treatment. Neurological examination identified 14 (23.3%) subjects with MD: upper limb symmetric action tremor in 13 (21.6%) and parkinsonism (rigidity and bradykinesia) in 1 (1.7%). No other MD was detected. The mean scores indicated mild clinical signs in all cases. Symptoms were considered subjectively mild with no functional interference. CONCLUSION: Almost one quarter of patients using CsA chronically presented MD, almost always mild and transitory action tremor, with minimal interference on daily living activities, not requiring any form of intervention in the majority of cases.

Frequency of obsessive and compulsive symptoms in patients with blepharospasm and hemifacial spasm.

BACKGROUND: Blepharospasm (BS) is a form of central focal dystonia recently associated with psychiatric disorders, particularly obsessive and compulsive symptoms. Hemifacial spasm (HFS) represents a focal myoclonus with peripheral origin in the facial nerve. OBJECTIVE: To determine the frequency of obsessive and compulsive symptoms in patients with BS in comparison with patients with HFS. METHODS: 30 patients from each group (BS and HFS) followed by the botulinum toxin clinic at the HC-UFPR were evaluated using a structured interview based on the DSM-IV criteria and the Yale-Brown scale. Results were compared by the mean two-tailed t test. RESULTS: We found obsessive or compulsive symptoms in 20 (66.6%) patients with BE and 21 (70%) with HFS. Yale-Brown scale scores for each group were higher among BS patients; however, diferences were not statisticaly significant. CONCLUSION: Our study did not show a significant diference in the comparison of the prevalence of obsessive and compulsive symptoms among patients with BS and HFS.

Cerebrotendinous xanthomatosis: report of two Brazilian brothers.

Cerebrotendinous xanthomatosis is a treatable rare autossomal recessive disease characterized by lipid storage secondary to a sterol 27-hydroxylase deficiency in the formation of cholic and chenodeoxycholic acids. We describe two Brazilian brothers with cognitive impairement and chronic diarrhea. One of them also presents bilateral cataracts. Neurological findings were progressive walking deficit, limb ataxia and pyramidal signs. Both patients had bilateral Achilles tendon xanthomata. Magnetic resonance image showed signal alterations in cerebellar hemispheres. We describe these cases with molecular genetic analysis confirming diagnosis and comparing with previous literature. The CYP27A1 gene study showed a C1187T mutation on exon 6.

Parkinson's disease and thyroid dysfunction.

BACKGROUND: Although no causal linkage between hypothyroidism and Parkinson's disease (PD) has been demonstrated so far, both share common manifestations and coexistence can be a source of diagnostic delay and confusion. PURPOSE: To assess thyroid function in patients with PD. SCOPE: Ninety-five PD patients and 102 age-matched controls were assessed for hypothyroidism through clinical evaluation and laboratory screening. RESULTS: In the PD group 13.7% were hypothyroid versus 10.8% in the control group. Statistical analysis did not show a significant difference (p = 0.3681). CONCLUSION: Although hypothyroidism was not more prevalent in our PD patients in comparison with the control group, we believe that given the potential overlap of symptoms and signs, thyroid function should be assessed in patients showing worsening of symptoms that cannot be explained by disease progression or resistance to therapy adjustment; screening should take into account the particular acute effect of levodopa on serum TSH levels.

[Central pontine and extra-pontine myelinolysis in an alcoholic patient without hydro-electrolyte disturbances: case report].

Central pontine myelinolysis (CPM) and extra-pontine myelinolysis (EPM) are different presentations of a demyelinating disorder of the brain more commonly associated with rapid correction of hyponatremia, spastic tetraparesia and pseudo-bulbar palsy. There are in the literature a few cases of CPM/EPM in patients without electrolyte disturbances. We report the case of a 39 year-old man with severe alcoholism, who presented with spastic tetraparesis and palsy of several cranial nerves, associated with lesions in the magnetic resonance compatible with CPM/EPM. The patient had a good follow-up after pulse therapy with corticosteroids.
