Role of CGRP-targeted therapies in acute and preventive management of migraine
Prof. Peter Goadsby, Prof. Min-Kyung Chu, 19 Dec 2023
Unmet needs remain in acute and preventive management of migraine despite availability of multiple treatment options in East Asia. At the 2023 International Headache Congress in Seoul, South Korea, Professor Peter Goadsby of King’s College London in London, UK, and Professor Min-Kyung Chu of Severance Hospital, Yonsei University in Seoul, South Korea, reviewed the role of calcitonin gene-related peptide (CGRP)–targeted therapies in migraine management, highlighting the efficacy and safety of the oral CGRP receptor antagonist (RA), rimegepant, in both acute treatment and prevention of migraine.
Healthy ageing: Early management of chronic inflammation & peripheral neuropathy in primary care
Dr. Fei Chan, Dr. Chi-Nam Lee, 24 Nov 2023
Ageing is characterized by systemic chronic inflammation, which is accompanied by age-related conditions (eg, type 2 diabetes mellitus [T2DM] and osteoarthritis [OA]) and complications (eg, peripheral neuropathy [PN]). This article summarizes insights from an industry-sponsored symposium on healthy ageing coordinated by the Hong Kong College of Family Physicians, which focused on the role of primary care physicians in management of chronic inflammatory conditions, and in early diagnosis and treatment of PN.
Optimizing care of adults with SMA in the new era of disease-modifying therapies
Prof. Maggie Walter, Dr. Shirley Pang, 24 Nov 2023

Spinal muscular atrophy (SMA) is a genetic disorder characterized by progressive muscle weakness and atrophy, leading to impaired motor function. Until recently, management of SMA was primarily supportive, but new treatments have improved disease prognosis. At an industry-sponsored symposium organized by the Hong Kong Neurological Society, Professor Maggie Walter of the Ludwig Maximilians University of Munich, Munich, Germany, discussed the importance of early detection of SMA and timely administration of disease-modifying therapies, such as the oral drug risdiplam (Evyrsdi®), to prevent rapid and irreversible loss of motor function in adult patients. Dr Shirley Pang of the Division of Neurology, Queen Mary Hospital, Hong Kong, shared local experience with the use of risdiplam in adults with SMA.

Updates in anticoagulation reversal and hyperkalaemia management in emergency setting
Prof. Adam J Singer, 14 Sep 2023
Major bleeding secondary to intake of direct oral anticoagulants (DOACs) and hyperkalaemia are two potentially fatal conditions encountered in the Accident and Emergency (A&E) department. At an industry-sponsored meeting organized by the Hong Kong College of Emergency Medicine, Professor Adam J Singer of the Stony Brook University Hospital in Stony Brook, New York, US, shared updates on management of these conditions, focusing on the role of andexanet alfa in reversing the effects of factor Xa (FXa) inhibitors, and discussed the emergence of sodium zirconium cyclosilicate (SZC) as the preferred potassium binder to treat life-threatening hyperkalaemia.
AAN 2023: Updates on role of ravulizumab in NMOSD and gMG
Dr. Sean Pittock, Dr. Glen Frick, Dr. Ali Habib, Mr. Stephan Ortiz, 12 Jun 2023
Dysregulation in the complement system is central to the pathogenesis of several diseases, including neuromyelitis optica spectrum disorder (NMOSD) and myasthenia gravis (MG). This article summarizes select presentations from the 2023 American Academy of Neurology (AAN) Annual Meeting covering the latest efficacy and safety data of ravulizumab, the long-acting complement component 5 (C5) inhibitor used to treat NMOSD and MG.
Experience with tumour-treating fields in operable and inoperable glioblastoma multiforme
Dr. Wai-Man Hung, Dr. Henry Sze, 07 Apr 2023
A 56-year-old male with good past health had an episode of new-onset epilepsy in April 2020. Brain MRI performed shortly after showed minor enhancement over the right temporal lobe, which was initially thought to be due to infectious encephalitis. Subsequent treatment with anti-infectives failed, and the patient’s condition began to deteriorate with more frequent seizures. He was put on an anticonvulsant, levetiracetam (1.5 g daily).
