RESUMEN
BACKGROUND: Transverse myelitis (TM) is a relatively uncommon condition, and vaccine-associated myelitis is even rarer. Concern regarding neurological complications following vaccination escalated following the report of TM during the safety and efficacy trials of the COVID-19 vaccine. CASE PRESENTATION: We report the first case of Longitudinal Extensive Transverse Myelitis (LETM) in Malaysia following administration of the chimpanzee adenovirus-vectored (ChAdOx1 nCoV-19) vaccine. A 25-year-old female presented with bilateral lower limb weakness and inability to walk with a sensory level up to T8 with absent visual symptoms. Urgent gadolinium-enhanced magnetic resonance imaging (MRI) of the spine showed long segment TM over the thoracic region. Cerebrospinal fluid autoantibodies for anti-aquaporin-4 and anti-myelin-oligodendrocyte were negative. A diagnosis of LETM following vaccination was made, and the patient was started on a high dose of intravenous methylprednisolone. The patient eventually made a recovery following treatment. CONCLUSION: LETM is a rare but serious adverse reaction following vaccination. Previously reported cases showed an onset of symptoms between 10 to 14 days post-vaccination, suggesting a delayed immunogenic reaction. However, the incidence of myelitis in COVID-19 is much more common, far greater than the risk associated with vaccination.

We discuss and illustrate various endovascular treatment options for intracranial aneurysms, to reflect common technique used in endovascular treatment of brain aneurysm. We select five cases of various aneurysm types to show assortments of endovascular treatment (EVT) are performed. Selective catheterization of the intracranial aneurysms and endovascular treatments are technically feasible, offering a viable alternative to the surgical approach. We discuss the radiographic features, clinical presentation, and strategies of endovascular treatment of intracranial aneurysms.

OBJECTIVE: To determine the associated factors of subclinical atherosclerosis measured with carotid intima media thickness (CIMT) among rheumatoid arthritis (RA) patients without any overt traditional cardiovascular (CV) risk factors. METHODS: Forty RA patients with matched age and gender healthy controls were recruited. Carotid ultrasound was performed to all subjects. CIMT was considered to be abnormally thickened if it was more than the 75th percentile matched for age and sex reference values. Univariate and multivariate analyses were performed to determine the association between the sociodemographics and disease characteristics of RA with thickened CIMT. RESULTS: Abnormally thickened CIMT were observed in 11 RA patients (27.5%) and in 4 control subjects (10%), p = 0.04. It was highly prevalent among RA patients with active disease (54.5% vs 17.2%), p = 0.02. Patients with thickened CIMT also tend to have erosive disease, p = 0.06. Seropositive rheumatoid factor (RF) patients also had significantly higher CIMT values as compared with sero-negative patients, p = 0.03. Multivariable logistic regression analysis revealed that active disease was independently associated with thickened CIMT. CONCLUSIONS: RA patients are at risk for subclinical atherosclerosis despite absence of traditional CV risk co morbidities and active disease was the independent factor associated with it.
