Ligamentous injuries of the lower limb are a common entity sustained during sports activities and military training. Magnetic resonance (MR) imaging of the knee and ankle is playing an increasingly important role in the detection, diagnosis and prognosis of these injuries and their associated complications. MR imaging with its exquisite soft tissue contrast resolution and multiplanar capability is increasingly seen as the modality of choice for evaluating ligamentous injuries of the knee and ankle. Representative knee and ankle MR studies from a tertiary referral hospital are used to illustrate both the normal appearance and typical radiological features of common ligamentous injuries of the knee and ankle. A thorough understanding of the MR appearances of these injuries is crucial to the radiologist and clinicians involved in the management of these patients.

In the perspective of recent bauxite mining in Malaysia, this review aims to identify the potential
environmental and health impacts on miners and surrounding communities. The environmental issues of
bauxite mining include, air, water and soil pollution due to bauxite dust; leaching of bauxite into water
sources resulting in reduced soil fertility as well as affecting agricultural food products and aquatic life.
Bauxite occupational exposure affects the health of miners, and has negative consequences on the health of
surrounding communities, such as increased respiratory symptoms, contamination of drinking water, other
potential health risks from ingestion of bauxite and heavy metals, including noise-induced hearing loss and
mental stress. This review discusses the processes of bauxite mining, its constituents and residual trace
elements, and their impact on the environment and health of exposed workers and communities. It also
explores the Malaysian legal requirements and standards of occupational exposure to bauxite.
