Adequate sampling of gross pathology specimens and attention to microscopic details is crucial in establishing the correct diagnosis in a patient, regardless of a benign pre-surgical diagnosis. Adenoma malignum is a rare HPV-negative variant of well-differentiated adenocarcinoma of the endocervix. It is difficult to diagnose in surgical pathology specimens due to its deceptively-benign appearance. This was a case of a 43-year-old woman with a history of menorrhagia and metrorrhagia and radiology interpretation of degenerating uterine fibroids...

Homozygous familial hypercholesterolaemia (FH) is a rare genetic disorder with aberrantly high level of low-density lipoprotein cholesterol (LDL-C) requiring multiple combined aggressive lipidlowering therapy to reduce the progression of atherosclerotic cardiovascular disease. Alirocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) has been approved for treatment of FH, which requires further lowering of LDL-C in addition to diet modification and maximally tolerated statin therapy. We report the response of short-term alirocumab treatment on a young patient with clinically and genetically confirmed FH, who suffered from acute coronary syndrome, and in particular, discussed the hypothesised legacy effect of PCSK9i...

Medium-chain acyl CoA dehydrogenase deficiency (MCADD) and other inborn errors of metabolism are common causes of Sudden Unexpected Deaths in Infancy (SUDI). If identified early or before metabolic decompensation, MCADD is manageable. In the US and other countries, identification of MCADD has improved through the routine use of newborn screening (NBS), which is able to identify most cases. This case study presented here occurred before NBS was implemented in Ohio for MCADD and outlines the typical clinical presentation, pathological features, and relevant biochemical and molecular markers for identifying MCADD...

Anaplastic large cell lymphoma, ALK-positive is a mature T-cell neoplasm that accounts for 10- 20% of paediatric non-Hodgkin lymphoma. Its frequency in infants and very young children is exceedingly rare and was rarely documented in the literature. The disease prognosis in this agegroup is unknown. We report two male patients who were diagnosed with ALCL-ALK(+) at the ages of 12 and 14 months, both presented with fever and leukemoid reaction, one was in stage I and the other in stage IV diseases. They were treated with APO-based chemotherapy and remained in complete remission for more than 7 years...

Hyalinising clear cell carcinoma (HCCC) of the lung is an extremely rare tumour that is just recently recognised as one of the salivary gland-type tumours (SGTT) in the latest WHO classification of thoracic tumours. Eleven cases have been reported in English literature since Joaquín et al. reported the first case. Given the very limited number of cases, the clinical and histological features of pulmonary HCCC are equivocal. Herein, we present two cases of pulmonary HCCC. The patients were a 66-year-old man and a 48-year-old woman...

INTRODUCTION: Thrombocytopenia is a common complication in dengue that sometimes necessitates platelet transfusion. Immature platelet fraction (IPF) measures immature platelets that indirectly reflect thrombopoiesis and is helpful in predicting platelet recovery. OBJECTIVES: This study aimed to evaluate the role of IPF% and identify its cut-off value in predicting platelet recovery in dengue patients with thrombocytopenia. MATERIALS AND METHODS: Serial platelet count and IPF results were obtained from fifty-four confirmed dengue patients with platelet count <50x109 /L...

INTRODUCTION: Less biopsies were expected when large scale social restrictions were enforced during COVID-19 pandemic. AIM: To compare the skin diseases prompting biopsy before and during the COVID-19 pandemic. MATERIALS AND METHODS: A retrospective study of skin diseases was performed; the skin problems were then grouped into major histopathological reactions. RESULTS: A total of 229 biopsies were performed before the COVID-19 outbreak, whereas only 160 biopsies were done during the pandemic...

INTRODUCTION: Cardiovascular disease and osteoporosis (OP) have been shown to have similar risk factors but studies have demonstrated contradictory results with regards to their associations. This study evaluated relationships between bone characteristics and cardiovascular risk factors among adults in selected urban areas in Malaysia. MATERIALS AND METHODS: A cross-sectional study was performed involving 331 subjects between 45-90 years recruited at a health screening programme...

INTRODUCTION: Patients who are suspected of having prostate cancer from screening tests require a tissue biopsy to confirm the presence of cancer. This study aims to compare the cost and cancer detection rate of two different biopsy protocols: 6-core transrectal (TR) approach, and transperineal (TP) saturation biopsy. METHODS: In this descriptive, retrospective study, we selected all prostate biopsies received by the diagnostic pathology department of a tertiary hospital in Malaysia in the year 2020, from adult patients for analysis...

INTRODUCTION AND OBJECTIVES: Prostate cancer is one of the most commonly diagnosed cancers in American men. Apelin is an endogenous peptide identified as the ligand of the G protein-associated apelin receptor. Apelin and apelin receptor have many tissues distribution and they participate in pathological processes, such as cancer. Apelin stimulates cancer angiogenesis. However, there are insufficient data in the literature regarding the role of apelin/apelin receptor in normal tissue, highgrade prostatic intraepithelial neoplasia, and prostatic adenocarcinoma tissues...

OBJECTIVES: To determine the incidence, causative pathogens, morbidities, mortality, and risk factors associated with blood culture-positive early-onset sepsis (EOS, ≤72 hours of age) in symptomatic neonates admitted to the neonatal intensive care units (NICUs) of a middle-income country. STUDY DESIGN: Retrospective cohort study using data submitted prospectively to the Malaysian National Neonatal Registry (MNNR). SETTING: 44 Malaysian NICUs...

Sarcopenia is a common condition in the geriatric population. It refers to age-related and progressive decline in muscle mass and function, which has a great impact on one's mobility and quality of life. Patients with sarcopenia are mainly treated with nutritional therapy, exercise therapy, or a combination of both. Since the identification of mesenchymal stem cells (MSCs) several decades ago, many studies have explored the application of MSCs in the field of regenerative medicine. MSCs are popular candidates for cell-based therapy owing to their multipotent nature and immunomodulatory properties...

Colorectal cancer (CRC) remains among the most commonly diagnosed cancers and has been on the rise. It is also one of the most lethal diseases globally, being the third leading cause of cancerrelated death. Depending on the stages and disease conditions, CRC is treated by surgery, chemo-, radio-therapy, immunotherapy or in combination. However, these therapies have subpar results with unwanted side effects, hence continuous effort is ongoing to explore new type of therapeutic modalities. Among the sub-types of CRC, KRAS, BRAF and NRAS mutated CRC comprise approximately 43%, 10% and 3% of the total cases, respectively...

Platelets, along with coagulation factors and vasculature, represent the three main compartments of hemostasis. Upon investigation of a suspected hemostasis disorder, platelet count, size and morphology often offer important clues to the diagnosis or help narrow the differential diagnosis. In this review, we describe a general approach to diagnosing platelet disorders, starting with easily obtained data such as findings of complete blood count (CBC) and microscopic review of a stained peripheral blood smear...

The genetic evolution of SARS-CoV-2 began in February 2020, with G614 spike protein strains superseding D614 strains globally. Since then with each subsequent mutations, the SARS-CoV-2 variants of concern, namely Alpha, Beta, Gamma, Delta and Omicron, superseded the previous one to become the dominant strain during the pandemic. By the end of November 2022, the Omicron variant and its descendent lineages account for 99.9% of sequences reported globally. All five VOCs have mutations located in the RBD of the spike protein, resulting in increased affinity of the spike protein to the ACE2 receptors resulting in enhanced viral attachment and its subsequent entry into the host cells...

Breast cancer remains a significant cause of mortality in females worldwide, despite advances in technology and treatment. MicroRNA expression in breast cancer is studied both as potential biomarkers and for therapeutic purposes. Accumulated evidence revealed microRNA profile of various types of cancer cells following antineoplastic treatment. The progression of research in this area provides better understanding on the anti-cancer mechanism of various natural compounds and drugs specifically on the microRNA regulation...
