Isolated renal metastasis after colon cancer.

Renal infiltration of colon adenocarcinoma is a rare event. The authors present the case report of a 52-year-old female who had a high carcinoembryonic antigen level 18 months after right hemicolectomy and a chemotherapy regimen to treat transverse colon adenocarcinoma. The patient presented cancer recurrence after 12 months, and underwent a paraaortic lymphadenoctomy and a second adjuvant chemotherapy with the folfox regimen. Abdomen computerized tomography revealed two solid masses in the right kidney, without evidence of any other metastatic sites. A nephrectomy was performed in the right kidney followed by adjuvant chemotherapy.

Functional bovine immunoglobulins in Boophilus microplus hemolymph.

The aim of the present work was to quantify the passage of bovine immunoglobulins into the hemolymph of the tick Boophilus microplus during the feeding process and to determine their antibody activity. The knowledge is of paramount importance when vector control or blocking of disease transmission is attempted by vaccination of cattle. Approximately 2% of bovine immunoglobulin present in the serum as determined by competitive ELISA was demonstrated in hemolymph of B. microplus and antibody activity against an antigen of B. microplus in the hemolymph of ticks fed on bovine immunized with the antigen purified from tick eggs was detected by Western blot assay. The antibody reactivity detected against the B. microplus antigen showed that functional antibodies are present in the hemolymph of fully engorged ticks for at least 48 h after completing the parasitic life cycle.

[Personal depositions of hospital nurses from the 50's: a help to the understanding of current nursing]. / Tomada de depoimento pessoal de enfermeiras hospitalares da década de 50: subsídios para a compreensão da enfermagem atual.

This study is a part of a more extensive project that proposes to rescue significant aspects related to nursing assistance evolution from the 1950s to the 1990s. Aiming at accomplishing this objective, the authors used the technique of oral declaration with active and retired registered nurses, in the context of a school-hospital at the state of São Paulo. The present study emphasizes the outcomes referring to the 1950s. The results show that the nurse's efforts are evident in the struggle for profession's recognition and prestige; there are intense and deep transformations related to nurse's new roles and their leadership as a member of the nursing staff and a member of the medical team.
