TB and STAFF

BCG vaccination will be offered to healthcare workers, irrespective of age, who fulfil all the following criteria:

1. previously unvaccinated (that is, without adequate documentation or a characteristic scar)
2. will have contact with patients or clinical materials.
3. are Mantoux (or interferon-gamma test for latent tuberculosis) negative.

All staff in contact with patients with smear positive pulmonary tuberculosis should be aware of the following principles.
-The importance of BCG immunisation as a basic protection
-The need to report to Occupational Health or senior ward staff if they are unusually susceptible e.g. transplant recipient taking immunosuppressive therapy, HIV positive.
-The extremely low risk of occupationally acquired tuberculosis where appropriate precautions are taken.
-The need to report any symptoms suggestive of tuberculosis to the Occupational
Health Department.

Staff in contact with open pulmonary tuberculosis do not normally need follow up. A decision on this will be made by the Occupational Health Department in conjunction with a Consultant Microbiologist or Consultant Respiratory Physician.

The Sandwich Sign

Transverse computed tomographic (CT) image obtained with oral and intravenous contrast material in a patient with mesenteric non-Hodgkin lymphoma (NHL). Image shows two large mesenteric lymphoma masses, which represent the halves of the sandwich bun (arrows), enveloping mesenteric fat and enhanced vessels.
Note that the enhanced small bowel lies outside of the sandwich. Extensive retroperitoneal lymphadenopathy (arrowheads) is present, as well.


Transverse CT image obtained with oral and intravenous contrast material in a patient who underwent left pelvic renal allograft transplantation 6 months earlier and now has mesenteric posttransplantation lymphoproliferative disorder (PTLD).
Mesenteric lymphoma mass (solid arrow) just to the right of the pelvic kidney (arrowhead) has produced a sandwich sign. Retroperitoneal lymphadenopathy (open arrows) is also seen.
