Case Reports
Hoffman's syndrome: pseudohypertrophic myopathy as initial manifestation of hypothyroidism. Case report.
The frequency of myopathy in hypothyroidism ranges from 30 to 80%. The major symptoms related are weakness, muscular cramps and myalgia. The pseudohyperthrophic form is called Hoffman's syndrome. ⋯ We report an adult male who developed muscular cramps, myalgia, weakness, pseudohyperthrophy, associated with facial edema and alteration of his voice. The muscle enzymes were increased and T4 was undetectable with a raised level of TSH. The myopathy was the initial manifestation of hypothyroidism in this case.

Comparative Study
[Epilepsy surgery in childhood: neuropsychological and quality of life assessments].
To perform neuropsychological and quality of life assessments before and after epilepsy surgery in children; to correlate these parameters with clinical findings. ⋯ Quality of life improvement was clearly correlated with seizure control; nevertheless, neuropsychological improvement depended on several factors, such as etiology, type of epilepsy and surgery.

Case Reports
[Botulinum toxin type B in the management of dystonia non-responsive to botulinum toxin type A].
Botulinum toxin (BTX) injection is the first choice treatment for focal dystonias. However 10% or more of patients who receive repetitive injections of BTX type A (BTX-A) lose response (secondary non-responders). One of the strategies to manage such patients is to treat them with another serotype. The aim of this article is to describe my experience with BTX type B (BTX-B) in the management of patients with focal dystonia who became secondary non-responders to BTX-A. ⋯ My findings confirm that BTX-B injections are a safe and effective option for the management of dystonia patients who become secondary non-responders to BTX-A. The results also underscore the need of individualizing dosage regimens before optimum results are achieved.

We present a case of a 46-year old woman with a ventral epidural angiolipoma at the lumbosacral level with erosion of the sacrum. About ninety cases of spinal angiolipomas have been previously described in the literature, most of them situated on the thoracic region, dorsal to the dural sac. Angiolipomas can be radically excised with a good prognosis even in the presence of bone erosion. We did not find any other angiolipoma at the sacral level surgically explored in the review of the literature.

Hypertrophic olivary degeneration (HOD) is a rare type of neuronal degeneration involving the dento-rubro-olivary pathway and presents clinically as palatal tremor. We present a 48 year old male patient who developed Holmes' tremor and bilateral HOD five months after brainstem hemorrhage. The severe rest tremor was refractory to pharmacotherapy and botulinum toxin injections, but was markedly reduced after thalamotomy. ⋯ Palatal tremor was absent in that moment and appears about two months later. The delayed-onset between insult and tremor following structural lesions of the brain suggest that compensatory or secondary changes in nervous system function must contribute to tremor genesis. The literature and imaging findings of this uncommon condition are reviewed.
