A Case of Arteriovenous Malformation Presenting as Wallenberg Syndrome / 대한이비인후과학회지

Lateral medullary syndrome, also known as Wallenberg syndrome, is characterized by sensory deficits affecting the trunk and extremities on the opposite side of the lesion, and the face and cranial nerves on the same side of the lesion. Other clinical symptoms and findings are dysphagia, slurred speech, ataxia, facial pain, vertigo with nystagmus, Horner's syndrome, diplopia, and possibly palatal myoclonus. The cause of this syndrome is usually occlusion of the posterior inferior cerebellar artery or vertebrobasillar artery. We observed a case of Wallenberg syndrome occuring secondary to the cavernous malformation and initially presenting as unilateral vocal cord palsy. The centrally-medicated vocal cord palsy is a rare cause of hoarseness, but should be considered in cases where no other local cause can be found.

A Case of Tramadol Induced Asthma Attack in a Patient with Samter's Triad / 대한이비인후과학회지

Samter's triad is a well known syndrome and is characterized by a triad of asthma, aspirin or NSAID sensitivity and chronic sinusitis with nasal polyp. Chronic sinusitis with Samter's triad is difficult to treat completely and has poor prognosis. Tramadol is a non-opioid analgesic that rarely shows respiratory suppression and is known to be relatively safe because it does not inhibit prostaglandin synthesis. For that reason, patients with asthma may avoid drug-induced exacerbations of the disease by substituting Tramadol for NSAIDs. We experienced a case of asthma attack in a patient with Samter's triad after Tramadol injection.
