2. The Value of Ultrasonic Scanning in the Differentiation of Acute Post-Transplant Renal Failure

Author

Barrientos, A., Leiva, O., Diaz-Gonzalez, R., Polo, G., Ruilope, L.M., Alcazar, J.M., Rodicio, J.L., Borobia, V., and Navas, J.

Abstract

In 43 renal transplant patients studied by ultrasonography there were 32 episodes of acute rejection and 17 of acute tubular necrosis. The size of the kidney increased in all cases. However, in 75 per cent of the patients with acute rejection the central echoes of the renal sinus increased conspicuously, while in 77 per cent of those with acute tubular necrosis the echogenicity of the central sinusal complex decreased. These findings may be expressions of different pathological lesions at the renal sinus level in patients with acute rejection and acute tubular necrosis, which would modify the acoustic interphase. Therefore, we have found panniculitis, vasculitis, thrombosis and inflammatory cellular infiltration of the urinary collecting systems to be significant in patients with acute rejection but not in those with acute tubular necrosis.

3. Testicular Malacoplakia

Author

Gonzalez, R. Diaz, Leiva, O., Palacios, J.J. Navas, Usera, G., Castillo, P. Gonzalez, Montalban, M.A., and Borobia, V.

Abstract

We report the twentieth case in the world literature of testicular malacoplakia. This lesion occurs mainly in middle-aged men, appearing clinically as epididymo-orchitis or enlargement of the testicle with fibrous consistency and some soft areas. Malacoplakia is now considered a nonspecific inflammatory granulomatous lesion subsequent to an infection by gram-negative bacteria. In our case Escherichia coli was cultured in the urine and testicular tissue. The ultrastructural study shows the histiocytic nature of the cellular infiltrate as well as the morphology of Michaelis-Gutmann bodies. Bacilliform structures were not found. The cellular and humoral immunological studies did not show alterations.

Abstract

We evaluated 137 patients with bladder cancer submitted to surgery in order to determine the usefulness of intravesical ultrasonography (IVU) in tumor staging. The characteristic scan images were defined for each tumor stage. The application of the ultrasound patterns yielded an accuracy rate of 91% for tumors Ta"1 and 71% for T4. Based on the results of this study, IVU does not appear to be useful as an intraoperative monitoring technique.

Abstract

A case of hypercalcemia associated with documented squamous cell carcinoma of the renal pelvis without bone metastasis is reported. High levels of cross-reacting parathyroid hormone-like material in serum and its presence in tumoral tissue were detected. To our knowledge this is the fourth case described in the literature and the first in which tumoral production of parathyroid hormone-like material is demonstrated.
