[Chronic ulnocarpal calcareous bursitis]. / Borsite calcarea cronica ulno-carpale.

There are reported three cases of nodular calcifications of the ulnocarpal region with very similar clinical and radiological aspects. The isolated nodules or the double, contigue one, are located near the pisiform bone, proximal to it, in the obliqual palmo-dorsal projection with semisupine hand. These nodules are projected on the ulnar styloid with the dorso-palmar projection. Clinical-radiological characteristics suggest a diagnosis of chronic bursitis that corresponds with the insertion on the pisiform bone of the flexor carpi ulnaris tendon. Differential diagnosis faces, besides the calcification in the tendinous sheths, also the accessory pisiform bone and the flake fractures, not joined, of the pisiform.

[The surgical exploration of the spermatic cord and testis with deferento-vesiculography (DVG) in the study of azoospermias (author's transl)]. / Il ruolo dell'esplorazione chirurgica funicolo testicolare con deferento-vesciculografia (dvg) nello studio delle azoospermie.

The Authors refer about their investigation of the azoospermias with surgical exploration of the spermatic cord and testis with deferento-vesiculography (DVG). Thirty-three patients were examined with DVG from a total of 50 observations. The Authors conclude that such investigation, associated to the study of others parameters in the male sterility, reveals itself very useful to provide information about azoospermias. Therefore, while testicular biopsy informs on the histomorfologic aspect of the testis, the DVG provides the best investigation of the morphology of the seminal ducts.

[Pyelocaliceal diverticula. Diagnostic problems: wash-out technique investigation and dynamic study (author's transl)]. / In tema di diverticoli pielici. Problemi diagnostici: esame con la tecnica della diuresi indotta e studio dinamico.

The authors evaluated the pyelocaliceal diverticula by means of high dosis contrast urography with nephrotomography and following wash-out and dynamic examination. Most of cases showed stasis in the diverticulum. In no case dynamic activity of diverticulum walls was founded.
