Q

Do you know two important case scenarios related to trigeminal neuralgia?
1. Paroxysmal attacks of pain at face + redness

  1. Paroxysmal attacks of pain at face + history of redness at face
A
  1. Paroxysmal attacks of pain at face + redness = varicella neuralgia.
  2. Paroxysmal attacks of pain at face + history of redness at face = post-herpetic neuralgia.

1st line of TTT of complex partial seizure…………..

A

1st line of TTT of trigeminal neuralgia………………. carbamazipine
1st line of TTT of bipolar in pregnancy………….….. carbamazipine
1st line of TTT of epilepdy in pregnancy…..……….. carbamazipine
1st line of TTT of complex partial seizure………….. carbamazipine

Carbamazepine is also linked to fetal abnormalities, but not with intellectual impairment, and should not be used during pregnancy.4

Lamotrigine poses a lower risk during pregnancy and can be prescribed to breastfeeding mothers, with 2.7% of babies having congenital abnormalities; however, it has limited efficacy in preventing mania.

Lithium is the most effective mood stabiliser,6 with demonstrated efficacy in the prophylaxis of postpartum relapse,7 and should be considered for women with seveare bipolar disorder. RACGP

Q

What is the treatment of choice for multiple sclerosis?

A

IV cortisone high dose

Corticosteroids are the mainstay treatment for acute relapses. Intravenous methylprednisolone is generally used, although oral methylprednisolone has been shown to have similar efficacy.14 Other options include adrenocorticotropic hormone or plasma exchange. Medical treatment is only necessary if the relapse symptoms have a significant impact on quality of life, as treatment may hasten the recovery from a relapse but not the likelihood of recovery or permanent disability.14
