    Transcript

    00:01 Here, we’ll take a look at mononeuritis multiplex.

    00:05 As the name implies, we have one nerve that is undergoing neuropathy or inflammation in multiple, multiple systems, is the topic for this section.

    00:17 Possible etiologies: Trauma, compression, diabetes, or vasculitides with or without connective tissue disease or infection related.

    00:30 Maybe it’s hepatitis B virus, HIV, hepatitis C virus.

    00:34 And one that you should know quite well is that polyarteritis nodosa may also present with mononeuritis multiplex.

    00:45 Other causes including leprosy, Lyme’s disease, sarcoidosis, or hereditary neuropathy with liability to pressure palsies, all possible causes of one nerve being affected in multiple locations.

    01:02 In summary: Risk factors: Diabetes, family history.

    01:06 Preventative medicine: Well, good control of blood sugar if you’re suspecting diabetes because there’s every possibility that you have many nerves that might be affected.

    01:14 Signs and symptoms: Well, it depends on which nerve has been affected.

    01:17 For example, if it’s a nerve down in the leg, then it’s common peroneal.

    01:21 You might have – A patient experiences foot drop or maybe it’s radial nerve also being affected.

    01:29 So therefore, there’s wrist drop, same patient, multiple nerves -- – or excuse me, multiple locations.

    01:36 One nerve in each location being affected.

    01:40 Diagnostic workup: EMG, electromyogram, appropriate labs.

    01:45 And treatment here would be, well, etiology-specific.
