Fulltext Treatment response in osmotic demyelination syndrome presenting as severe parkinsonism, ptosis and gaze palsy

Abdul Halim S, Mohd Amin NA

Osmotic demyelination syndrome commonly affects the pons and infrequently involves the extrapontine region. We report a patient with severe hyponatraemia who developed osmotic demyelination syndrome as a consequence of rapid sodium correction. The condition manifested as acute severe parkinsonism, bilateral ptosis and gaze impairment. MRI revealed typical features of central pontine and extrapontine myelinolysis. The patient improved gradually after treatment with a combination of levodopa, intravenous immunoglobulin and dexamethasone. However, it is important to emphasise that the improvement of neurological symptoms is not necessarily causal with these experimental therapies.

"Mummy, my eyelids are heavy": A case series of juvenile myasthenia gravis

Krishna L, Abdul Jalil NF, Lott PW, Singh S, Choo MM

Eur J Ophthalmol, 2021 Mar;31(2):NP119-NP122.
PMID: 31390886 DOI: 10.1177/1120672119867605

PURPOSE: To report three cases of juvenile myasthenia gravis aged between 18 and 24 months with ocular symptoms as their first presentation.
METHOD: A case series.
RESULTS: We present a case series of juvenile myasthenia gravis in a tertiary centre in Malaysia. Two of the three cases consist of a pair of twins who presented with ptosis of bilateral eyes; the first twin presented 4 months later than the second twin. These two cases were positive for anti-acetylcholine receptor antibodies and had generalized myasthenia gravis, whereas the other case was negative for receptor antibodies and was purely ocular myasthenia gravis.
CONCLUSION: Juvenile myasthenia gravis is relatively rare in toddlers. Early diagnosis and commencement of treatment is important to slow the progression of the disease and avoiding life-threatening events.

Fulltext "Why do I always see double?" A misdiagnosed case of ocular myasthenia gravis for 10 years

Yousuf UA, Yashodhara BM, Thanigasalam T, Ting HS

BMJ Case Rep, 2014 May 02;2014.
PMID: 24792021 DOI: 10.1136/bcr-2013-203488

A 58-year-old man presented with diplopia and partial ptosis for 10 years. It was non-progressive in nature, despite inadequate medical attention the patient received from non-specialists/general practitioners. He did not have fatigability or diurnal variation in weakness and was clinically stable without exacerbations of disease for a decade. He did not have features of Graves's disease, oculopharyngeal dystrophy, cranial nerve paralysis, polymyositis and stroke. The possibility of an atypical presentation of myasthenia gravis (MG) was considered and the patient was evaluated. Ice pack test was negative, Cogan's lid twitch (CLT) test was positive and high titres of acetylcholine receptor antibodies (AChR Ab) suggestive of MG were found. He was treated accordingly with a very good response.
