Prominent publications by Yee Cheun Chan

KOL-Index: 12798 . INTRODUCTION: Nerve conduction is often regarded as more sensitive than ultrasonography (US) for diagnosing carpal tunnel syndrome (CTS). The diagnostic value of US derives from median nerve enlargement occurring at both ends of the carpal tunnel resulting in a dumbbell-like swelling from carpal tunnel pressure. An important reason for the inferior sensitivity of US may be because ...

KOL-Index: 9705 . BACKGROUND: People with diabetes mellitus (DM) sometimes present with acute or subacute, progressive, asymmetrical pain and weakness of the proximal lower limb muscles. The various names for the condition include diabetic amyotrophy, or diabetic lumbosacral radiculoplexus neuropathies. Some studies suggest that it may be due to immune-mediated inflammatory microvasculitis causing ischaemic ...

KOL-Index: 9505 . An intraoperatively enlarged engorged median nerve has been described as typical of patients with carpal tunnel syndrome (CTS). Although many studies of CTS have addressed median nerve enlargement, little is known about the usefulness of Doppler methods in detecting median nerve engorgement combined with nerve cross-sectional area (CSA). In a retrospective study of hands referred for ...

KOL-Index: 7150 . OBJECTIVE: To comprehensively investigate the relationship between antibodies to single glycolipids and their complexes and Guillain-Barré syndrome subtypes and clinical features. METHODS: In acute sera from 199 patients with Guillain-Barré syndrome, immunoglobulin G (IgG) antibodies to glycolipids and ganglioside complexes were tested using ELISA against individual antigens from single ...

KOL-Index: 6475 . OBJECTIVE: Recent studies suggest that high resolution ultrasonography (HRU) is useful in evaluating ulnar neuropathy (UN) at the elbow. These studies do not include UN outside the elbow and lesions related to previous trauma. We investigate diagnostic utility of HRU in UN at any location of traumatic and non-traumatic etiology. METHODS: Patients with clinically suspected and ...

KOL-Index: 5720 . Cerebrospinal fluid (CSF) protein level, cell count, and its relationship to the timing of lumbar puncture were collected from patients with Guillain-Barré syndrome (GBS) and Miller Fisher syndrome (MFS) from various Asian centers. A total of 507 patients with GBS were studied. Overall, 56% had elevated CSF protein level. This was significantly lower than that reported in a recent Dutch ...

KOL-Index: 5680 . Pathophysiologically, Guillain-Barré syndrome is divided into demyelinating and axonal subtypes. Recent studies have shown that serial nerve conduction studies (NCSs) are required to differentiate a demyelination-remyelination pathophysiology from one with axonal nodal reversible conduction failure. Cases with an overlap of pharyngeal-cervical-brachial weakness and Fisher syndrome (PCB/FS) ...

KOL-Index: 5337 . OBJECTIVE: To study the clinical profile of Guillain-Barré syndrome (GBS) patients who died in 4 Asian countries in order to understand factors underlying any variation in mortality. METHODS: Retrospectively reviewed medical records of GBS patients who died in 7 hospitals from 4 Asian countries between 2001 and 2012. Baseline characteristics, timing and causes of death were ...

KOL-Index: 5232 . BACKGROUND: Two small studies had evaluated the efficacy of rTMS in migraine. One tested high frequency rTMS over the dorsolateral prefrontal cortex while the other evaluated 1 Hz rTMS over the vertex. AIM: To test the feasibility of 10 Hz rTMS of motor cortex as an adjunctive therapy in patients with chronic migraine Materials and Methods: We randomized (2:1 ratio) chronic migraine ...

KOL-Index: 5045 . The S218L CACNA1A mutation has been previously described in two families with familial hemiplegic migraine. We present three siblings with the mutation with the novel association of childhood seizures, and highlight the dynamic changes seen on electroencephalography during hemiplegic migraine attacks. Depressed activity contralateral to the hemiparesis was seen on electroencephalography ...

KOL-Index: 4792 . BACKGROUND: There have been no prior studies assessing the status of undergraduate headache training and education in Singapore. Unmet needs of undergraduate medical students in terms of knowledge-practice gaps pertaining to diagnosis and management of headache disorders are unknown. The possible underemphasis of this aspect of the curriculum as compared to other chronic conditions such as ...

KOL-Index: 4719 . OBJECTIVE: To highlight the potential usefulness of nerve ultrasonography to identify lymphomatous peripheral nerve infiltration in patients with lymphoma. METHODS: We performed electrodiagnostic studies and nerve ultrasonography in 3 patients with lymphoma presenting with focal peripheral neuropathy. RESULTS: In all 3 patients, electrodiagnostic studies proved focal involvement of the ...

KOL-Index: 4380 . INTRODUCTION: In this study we propose electrodiagnostic criteria for early reversible conduction failure (ERCF) in axonal Guillain-Barré syndrome (GBS) and apply them to a cohort of GBS patients. METHODS: Serial nerve conduction studies (NCS) were retrospectively analyzed in 82 GBS patients from 3 centers. The criteria for the presence of ERCF in a nerve were: (i) a 50% increase in ...

Raised anti-GQ1b antibody is associated with Miller Fisher syndrome, Guillain-Barre syndrome (GBS) with ophthalmoplegia, Bickerstaff's brain stem encephalitis, acute ophthalmoparesis without ataxia and ataxic GBS without opthalmoplegia. We report a rare case of acute ophthalmoplegia associated with anti-GQ1b antibody that also had pupillary areflexia. A 35-year-old Chinese lady presented ...
