Knowledge, perceptions and practices on healthcare waste management and associated occupational health hazards among healthcare professionals in the Colombo District, Sri Lanka: a cross-sectional study.

Background: Proper Healthcare Waste (HW) management is directly influenced by the knowledge and attitudes of Healthcare Professionals (HCP). However, studies that characterize the knowledge and practices of HCP on HW management are limited in Sri Lanka. This study was conducted to characterize the knowledge, perceptions and practices of HCP on the management of HW and to determine the risk factors influencing HW related occupational health hazards in the Colombo District of Sri Lanka.

Evaluation of average glandular dose (AGD) in screening and diagnostic digital mammography and digital breast tomosynthesis (DBT) towards establishing a reference dose range band (DRB): a developing country experience.

This study represents the first national survey conducted in Sri Lanka to establish national diagnostic reference levels (NDRLs) for screening and diagnostic acquisitions in digital mammography (2D-DM) and digital breast tomosynthesis (DBT). Additionally, the study investigated the relationship between average glandular dose (AGD) and compressed breast thickness (CBT) and introduced a novel concept called dose range bands (DRBs) as a tool for optimizing radiation dose in mammography. DICOM metadata was used to extract dose data and exposure parameters from women undergoing either screening (350) or diagnostic (750) DM.

Unruptured sinus of Valsalva aneurysms - Multimodality imaging correlation helps determine indications and approaches for repair.

Unlabelled: Despite conventional advice to watch-and-wait, unruptured sinus of Valsalva aneurysms (SOVA) of the non-coronary sinus may produce symptoms that prompt corrective surgery early. A case of a 51-year-old man is illustrated. He presented with shortness of breath and on and off chest pains, was noted to have a large SOVA of non-coronary sinus (NCC), compressing the left atrium with risk of systemic embolism due to presence of spontaneous echocardiography contrast with early thrombus formation.

Late-onset neurodegenerative manifestations in patients with cirrhosis: acquired hepatocerebral degeneration - a neglected diagnosis.

Acquired hepatocerebral degeneration (AHCD) is an acquired, extrapyramidal, neurodegenerative condition, encountered in patients with cirrhosis. It is an uncommon and usually irreversible condition, resulting in widespread cerebral, basal ganglia and cerebellar damage. We describe here four cases of AHCD, with varying presentations, highlighting the need for increased awareness of this condition, to avoid diagnostics delays and unnecessary management.
