[Comparative study of bone mass in various places in patients with osteoporosis]. / Estudio comparativo de la masa ósea en diversas localizaciones en pacientes con osteoporosis.

Radiogrametric values of the second right metacarpal and data obtained by radiographic densitometry in the lumbar cord and the neck of the right femur have been studied comparatively in sixty two women and 6 men, with ages within 24 and 82 years and suspicion of suffering osteoporosis. Cases have been divided into four groups depending on the presence of vertebral fractures (Group I) and the densitometric results at the level of the lumbar cord. The comparison has shown a poor correlation between lumbar densitometric values and the radiogrametry, both in the cases considered normal and pathogenic. We conclude that the radiogrametry has a small discriminant value in the diagnosis of the post-menopause osteoporosis. On the contrary, absorptiometry in the neck of the femur has a significant correlation with radiogrametry in healthy individuals.

[Primary non-Hodgkin's lymphoma of the prostate gland]. / Linfoma no-Hodgkin primitivo de glándula prostática.

The clinical, morphological, microscopic, immunohistochemical, and ultrastructural findings in a case of primary non-Hodgkin's malignant lymphoma of the prostate gland is reported. The presenting features were not distinct from those of nodular hyperplasia. Following biopsy, the lesion was classified as monoclonal IgM-secreting, low grade, malignant beta-lymphoma. We discuss the good outcome of this case and the prognostic value of several clinical and morphological parameters. Finally, the therapeutic possibilities for this tumor type are compared with those of extranodal lymphomas in other sites.
