Experimental and clinical studies have conclusively demonstrated that lowering elevated low-density lipoprotein cholesterol levels results in fewer major adverse cardiac events. Over the past few decades, statins have become the mainstay of lipid-lowering therapy, contributing significantly to the reduction of lipids, and providing patients with a cost-effective approach. ⋯ We further discuss the clinical trials that have evaluated the safety and efficacy of these alternative and adjuvant therapies as well as their implications for practical use. These drugs target levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, or lipoprotein(a) as treatments for hyperlipidemia and atherosclerotic cardiovascular disease.

Lipoid pneumonia occurs due to the accumulation of lipids within the lung tissue. Autopsy series have reported an incidence of 1.0-2.5% in adult and 8.8% in children. Lipoid pneumonia can be from an exogeneous or an endogenous source. ⋯ A wedge resection was performed with histopathologic findings consistent with exogenous lipoid pneumonia with granulomatous reaction. We report clinical, radiological, and pathological features of exogenous lipoid pneumonia secondary to chronic aspiration mimicking invasive adenocarcinoma. A high index of suspicion for exogenous lipoid pneumonia should be maintained, especially when evaluating patients with abnormal chest radiographic findings and risk factors for aspirations.

Posterior circulation ischaemic stroke (PCIS) is a disease of high mortality and morbidity. They account for 20-25% of all ischaemic strokes. However, it is relatively under-researched and requires more clinical attention, since it carries worse functional outcomes. ⋯ Aspirin use also significantly improves survival outcomes. While intravascular and intra-arterial thrombolysis improve clinical outcomes, this is not proven conclusively for stenting and angioplasty. Future research on PCIS can focus on multi-centre epidemiological studies, clinically significant anatomical variants, and collateralisation.
