RESUMO
The duodenum is the most common site of cholecystoenteric fistulation resulting from cholecystitis or empyema of the gallbladder. This rare condition is usually only diagnosed intraoperatively and managed incidentally. This paper presents the endoscopic diagnosis of a case of cholecystoduodenal fistula arising from the late presentation of empyema of the gallbladder and its subsequent drainage through the fistula. As far as we can determine, this is the only reported case of opportunistic drainage of an empyema of the gallbladder through a concurrent cholecystoduodenal fistula.

A young lady who was treated for early squamous cell carcinoma of cervix presented with perforated appendicitis. Appendicectomy was done and the histopathology was reported as metastatic squamous cell carcinoma. Squamous cell carcinoma of the cervix metastasizing to the appendix is extremely rare and we previously unreported.

There is a well-documented correlation between the number of T-lymphocytes in the bone marrow graft and subsequent development of acute graft-versus-host disease after allogeneic bone marrow transplantation. The incidence of acute graft-versus-host disease may be decreased with elimination of mature T-lymphocytes from the bone marrow graft. We have developed an immunomagnetic separation procedure using an avidin-based magnetic affinity cobalt colloid. Bone marrow cells were incubated with a combination of CD2, CD3, CD4, and CD8 monoclonal antibodies. The cells were washed and then incubated with the biotinylated, affinity-purified IgG fraction of goat anti-mouse immunoglobulins followed by an avidin-based magnetic affinity colloid. The cells were then run through a high-magnetic gradient separation column utilizing an external samarium cobalt magnet. The number of residual T-lymphocytes was assessed by limiting dilution analysis of clonogenic T-lymphocytes. This procedure produces an approximately 1.7-log reduction of antibody-reactive cells with 45% recovery of hematopoietic progenitors (granulocyte-macrophage colony-forming cells, GM-CFC). This causes a reduction of T-lymphocytes in the bone marrow graft to approximately 5 x 10(5) cells/kg body weight.
