Methaemoglobinaemia due to alkyl nitrites in a patient with suspected traumatic injuries.

A man in his 60s with no relevant previous medical history presented to an urban, major trauma centre by ambulance after being found with a head injury in a nightclub. The paramedics reported he was hypoxic, hypotensive and tachycardic with altered mental status. At the emergency department, he had oxygen saturations of 85% despite high-flow oxygen and was hypotensive at 88/43mmHg.

Transthoracic Littre's hernia presenting with faecopneumothorax following perforation of the Meckel's diverticulum: a late complication of oesophagectomy.

A Littre's hernia is an unusual phenomenon where a Meckel's diverticulum protrudes through a potential abdominal opening. We wish to present a unique case of a 79-year-old man with respiratory distress following a fall from standing, initially managed as a haemothorax. After a chest drain was placed, bowel contents were drained from the pleural cavity and he was taken to theatre.

Controlled laser texturing of titanium results in reliable osteointegration.

We have developed a laser-textured superhydrophilic Ti-6Al-4V surface with unique surface chemistry and topography that substantially promotes osteoblast adhesion in culture. Here we investigate the osteointegration of laser-textured implants in an ovine model. Our hypothesis was that laser-textured implants, without any surface coating (LT), would encourage comparable amounts of bone-implant contact and interfacial strength when compared with widely accepted hydroxyapatite (HA) coated implants.
