RESUMEN
Botulinum toxin type A (BTA) is widely used for both medical treatment and cosmetic purposes. A 46-year-old woman presented with progressive generalized weakness and dysphagia. The patient had injected BTA into her both of her calves by herself for cosmetic purposes. Repetitive nerve stimulation of the right facial nerve demonstrated reduced compound muscle action potential amplitudes of the orbicularis oculi and nasalis muscles, and a reduced response to low-frequency, repetitive stimulation. The possibility of iatrogenic botulism should be considered when using BTA.

Seizure-associated nose wiping occurs usually during postictal period and is more frequent in temporal than extratemporal lobe epilepsy. The hand used to wipe the nose is highly suggestive of ipsilateral partial seizure onset. We describe a patient with the left mesial temporal lobe epilepsy, who showed ictal nose wiping by the left hand. The hypothetical mechanism remains unknown but may be a response to olfactory aura or increased ictal nasal secretions. In this patient, subtraction ictal SPECT coregistered to MRI (SISCOM) study revealed hyperperfusion mainly in the left temporal lobe, especially amygdala. Our patient may support an important role of amygdala concerned with olfactory system or autonomic activity in provoking nose wiping.
