Fulltext Traumatic Globe Luxation and Optic Nerve Avulsion: A Case Report and Literature Review

Kwan Joo Ern K, Muhammed J, Amin NH, Jameelah S

Cureus, 2024 Jan;16(1):e53150.
PMID: 38420068 DOI: 10.7759/cureus.53150

Traumatic globe luxation associated with optic nerve avulsion is rare. We describe a case of a 42-year-old Indian gentleman who was involved in a motor vehicle accident (MVA). He sustained a deep laceration wound from the right side of the nose extending to the left medial canthal region and left eyelid. The left globe was not visualized, and only the left optic nerve stump was seen. A computerized tomography (CT) scan showed a left globe dislocated inferotemporal with discontinuity of the left optic nerve, inferior rectus, and lateral rectus muscle. There were also comminuted fractures at the floor and lateral wall of the left orbit with significant lateral displacement of the bone fragments. He underwent left eye enucleation, toilet, and suturing of the laceration wounds and open reduction internal fixation (ORIF) of the fractures. We report this case as it is not commonly seen in Malaysia.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is primarily a familial disease with autosomal dominant inheritance. Incomplete penetrance and variable expression are common, resulting in broad disease spectrum. Three patterns of phenotypic expression have been described: (1) "classic" subtype, with predominant right ventricle involvement, (2) "left dominant" subtype, with early and dominant left ventricle involvement, and (3) "biventricular" subtype, with both ventricles equally affected. Genotypephenotype associations have been described, but there are other genetic and non-genetic factors that can affect disease expression. We describe two different phenotypic expressions of ARVC in a family.
Fulltext Cardiomyopathy following COVID-19 vaccination in a patient with systemic lupus erythematosus

Bhullar AK, Chew ZC, Ong PS, Khor CG, Mohd Amin NH

Mod Rheumatol Case Rep, 2023 Jan 03;7(1):87-91.
PMID: 36069645 DOI: 10.1093/mrcr/rxac070

There are an increasing number of reports of myocarditis associated with mRNA-based COVID-19 vaccination. We describe the case of a female patient with underlying systemic lupus erythematosus, who developed heart failure symptoms following a second dose of the BNT162b2 vaccine. Despite her history of refractory systemic lupus erythematosus, the disease remained stable after she began rituximab treatment. She underwent serial transthoracic echocardiogram and cardiac magnetic resonance imaging for the evaluation of cardiomyopathy. She showed improvement in cardiac function after treatment with glucocorticoids and intravenous immunoglobulin therapy.
Association of CYP2C19*2 polymorphism with clopidogrel response and 1-year major adverse cardiovascular events in a multiethnic population with drug-eluting stents

Tan SSN, Fong AYY, Mejin M, Gerunsin J, Kong KL, Chin FYY, et al.

Pharmacogenomics, 2017 08;18(13):1225-1239.
PMID: 28745576 DOI: 10.2217/pgs-2017-0078

BACKGROUND: Patients undergoing elective percutaneous coronary intervention (PCI) with drug-eluting stents (DES) who have impaired clopidogrel response, have a higher risk of subsequent major adverse cardiovascular events (MACE).
AIM OF THE STUDY: To establish the relationship between CYP2C19 genotype, clopidogrel responsiveness and 1-year MACE.
MATERIALS & METHODS: Aspirin/clopidogrel responses were assessed with Multiplate Analyzer and CYP2C19*2 allele by SpartanRx.
RESULTS: A total of 42.0% carried ≥1 CYP2C19*2 allele. Prevalences of aspirin and clopidogrel high on-treatment platelet reactivity (HPR; local cutoffs: 300 AU*min for aspirin and 600 AU*min for clopidogrel) were 11.5% and 19.8% respectively. In multivariate ana-lysis, clopidogrel HPR was found to be an independent predictor for 1-year MACE (adj HR: 3.48, p = 0.022 ).
CONCLUSION: Having clopidogrel HPR could be a potentially modifiable risk factor guided by phenotyping.
Fulltext Characteristics of patients admitted with heart failure: Insights from the first Malaysian Heart Failure Registry

Wan Ahmad WA, Abdul Ghapar AK, Zainal Abidin HA, Karthikesan D, Ross NT, S K Abdul Kader MA, et al.

ESC Heart Fail, 2024 Apr;11(2):727-736.
PMID: 38131217 DOI: 10.1002/ehf2.14608

AIMS: Heart failure (HF) is a growing health problem, yet there are limited data on patients with HF in Malaysia. The Malaysian Heart Failure (MY-HF) Registry aims to gain insights into the epidemiology, aetiology, management, and outcome of Malaysian patients with HF and identify areas for improvement within the national HF services.
METHODS AND RESULTS: The MY-HF Registry is a 3-year prospective, observational study comprising 2717 Malaysian patients admitted for acute HF. We report the description of baseline data at admission and outcomes of index hospitalization of these patients. The mean age was 60.2 ± 13.6 years, 66.8% were male, and 34.3% had de novo HF. Collectively, 55.7% of patients presented with New York Heart Association (NYHA) Class III or IV; ischaemic heart disease was the most frequent aetiology (63.2%). Most admissions (87.3%) occurred via the emergency department, with 13.7% of patients requiring intensive care, and of these, 21.8% needed intubation. The proportion of patients receiving guideline-directed medical therapy increased at discharge (84.2% vs. 93.6%). The median length of stay (LOS) was 5 days, and in-hospital mortality was 2.9%. Predictors of LOS and/or in-hospital mortality were age, NYHA class, estimated glomerular filtration rate, and comorbid anaemia. LOS and in-hospital mortality were similar regardless of ejection fraction.
CONCLUSIONS: The MY-HF Registry showed that the HF population in Malaysia is younger, predominantly male, and ischaemic-driven and has good prospects with hospitalization for optimization of treatment. These findings suggest a need to reassess current clinical practice and guide resource allocation to improve patient outcomes.
