[Renal mass as the initial manifestation of a metastasized oat-cell]. / Masa renal como primera manifestación de un oat-cell metastatizado.

Renal metastasis of localized tumours in the economy are rare. In our series of 162 renal tumours only 3 were metastatic. Even more unusual is that the metastasis should be the presenting form. Such is the case we are reporting: a 59 year-old male complaining from back pain and toxic syndrome. Supplementary examinations were performed sequentially until arriving at an open biopsy which confirmed the oat cell histology. The paper explains the results from the various examinations. The ominous prognosis of this histology is illustrated.

A new method for detection and localization of urinary infection: the fluorescence antibody test.

The urinary sediment of 56 patients with active urinary infection were studied through a direct immunofluorescence technique in order to detect the presence of antibody-coated bacteria (ACB). In 35-36 pyelonephritis cases the results were positive. However, in 11 cases with lower urinary infection there was no sign of ACB. A pathological intravenous pyelogram (IVP) was obtained from 33 pyelonephritic cases. In 32 cases the fluorescent antibody (FA) test was positive, in one it was negative. In the remaining 3 pyelonephritic cases the IVP was normal and the FA test positive. In these 3 cases cystograph revealed presence of urethral-vesical backflow. A good statistical correlation was obtained by comparing the positive results of the test with the titer of sericeous antibody against the bacteria causing the infection. We have introduced some variations to the original method which permits simpler administration of this test to ambulatory patients and increases the diagnostic possibility of those cases of bacteriuria less than 100,000 bacteria/ml.

A new method for detection and localization of urinary infection. The fluorescence antibody test.

The urinary sediment of 56 patients with active urinary infection were studied through a direct immunofluorescence technique in order to detect the presence of antibody-coated bacteria. In 35-36 pyelonephritis cases the results were positive. However, in 11 cases with lower urinary infection there was no sign of antibody coasted bacteria. A pathological intravenous pyelogram (IVP) was obtained from 33 pyelonephritic cases. In the flurorescent antibody (FA) test was positive, one was negative. In the remaining three pyelonephritic cases the IVP was normal the the FA test positive. In these three cases, cystography revealed the presence of ureterovesical backflow. A good statistical correlation was obtained by comparing the positive results of the test with the titer of serum antibody against the bacteria causing the infection. We have introduced some variation to the original method which permits simpler administration of this test to ambulatory patients and increases the diagnostic possibility of those cases of bacteriuria less than 100,000 bacteria/ml.

Preliminary report of an immunological study in urological cancer.

In this study, 32 cases of cancer of the genito-urinary tract are discussed from the viewpoint of immunology. In eight cases treated surgically, there has been no evidence of recurrence over a period of 1-4 years. Those with a good immunological response have a satisfactory course. Patients with a good response have been treated by radical surgery depending on the stage of the tumour, whilst those with a poor response have been treated less radically by reduction of the tumour mass in the hope that a better response may develop. The authors of this report feel that the 'inhibition of the lymphocyte migration test' is a very important factor to evaluate in the study and immunological evolution of the patient. Also, and concerning cases with good immunological response, the poor results after surgery makes us consider the importance and value of blocking factors of the serum closely related to the B type lymphocytes.
