Pyoderma gangrenosum: a rare cause of breast ulceration.

Breast ulceration is an alarming sign for clinicians and places a significant physical and psychological burden on the patient. We report a rare presentation of pyoderma gangrenosum of the breast in a patient known to have ulcerative colitis but no active underlying disease process and no history of breast tissue trauma. This case report with literature review highlights the importance of considering pyoderma gangrenosum as a differential diagnosis in breast ulcers.

Is the Stryker Revolution mixing system fit for purpose? Reliability and a micro-CT assessment of cement porosity.

The Stryker Revolution(TM) is a new mixing system that employs a high vacuum and a motorised mixing spatula in an effort to reduce cement porosity. We have compared Revolution(TM) with Depuy Cemvac(®), in terms of system reliability and cement porosity. Standardised Simplex P(®) and SmartSet(®) HV cement samples were produced using both mixing systems and analysed using a micro-CT scanner.

Incidence and predictors of acute mountain sickness among trekkers on Mount Kilimanjaro.

We investigated the incidence of AMS amongst a general population of trekkers on Mount Kilimanjaro, using the Lake Louise consensus scoring system (LLS). Additionally we examined the effect of prophylactic acetazolamide and different ascent profiles. Climbers on 3 different ascent itineraries were recruited.
