An unusual occurrence of penetrating aortic arch injury by a ball-point pen: a case report and review of the literature.

Background: Aortic arch injuries account for about 8% of thoracic aortic injuries. Penetrating zone I neck injuries account for 18% of vascular injuries in the neck and have great potential to traverse to involve thoracic vascular structures as well. The hard and soft signs of vascular injury facilitate triage of patients on an individual basis.

Mature cystic teratoma of anterior mediastinum in a 4-month-old infant: a rare case report.

Teratomas of anterior mediastinum are rare tumors and are often slow growing, asymptomatic and detected incidentally on chest imaging. We report, a rare case of an anterior mediastinal teratoma occurring in early childhood. A 4-month-old male infant presented to the pediatric unit of our hospital with a 2-week history of a progressive difficulty in breathing and stridor.

Hand Colonization with Gram-Negative Organisms of Healthcare Workers Accessing the Cardiac Intensive Care Unit: A Cross-Sectional Study at the Uganda Heart Institute.

Background: Hands of healthcare workers (HCWs) are vehicles for pathogens responsible for healthcare-associated infections (HAIs). Following the identification of Gram-negative organisms (GNOs) in all cases of HAIs in the cardiac intensive care unit (ICU), we sought to determine the burden of hand colonization with GNOs among healthcare workers who access the cardiac ICU.

Methods: We retrospectively reviewed results from surveillance cultures of fingertip imprints of HCWs who access the cardiac ICU at the Uganda Heart Institute.
