[Hysterography and hysteroscopy. Comparative study of 50 patients].

Hysterography and hysteroscopy have been compared in the diagnosis of endouterine benign pathology, in a group of 50 patients, complaining meno-metrorrhagia, sterility, infertility or amenorrhea. Hysterography resulted more sensible (95.3%), but less specific (86.

[Comparison between isteropac and a new non-ionic contrast medium for hysterosalpingography (B-15000)].

The authors refer the results of a double blind hysterosalpingographic study with a traditional ionic contrast medium (Isteropac) and a new non-ionic one (B-15000). Both the contrast have provided good quality images, without significant intolerance. Moreover the new non-ionic contrast medium has shown an easier utero-tubal transit with a sensible reduction of the examination length and a better diagnostic result.

Evolution of a mural thrombus in false aneurysm: CT demonstration.

A case of postoperative false aneurysm of the ascending aorta with serial CT and angiographic demonstration is described. Some considerations on the behavior of early thrombosis are discussed.

[Peritubal adhesions and hysterosalpingography].

Hysterosalpingography cannot directly show pelvic adhesions due to pelviperitonitis, salpingitis, perimetritis or parametritis. Nevertheless this method is able to evidence an eventual tubal involvement by adhesive tissue. Located pools of contrast medium around the tubae is a well known radiological sign, but not the only nor the most frequently one observed.

[A rare case of hemangiomatous tumor of the posterior urethra].

The authors report a rare case of a vascular neoplasm of the posterior urethra in an adult. They emphasize the histological and etiopathogenic features of the disease, and discuss the prognostic and therapeutical aspects of its management.

[Prone position in hysterosalpingography].

The authors discuss the importance of prone hysterosalpingography to the aim of a careful tubal examination. Nearly all the complete or partial tubal obstructions, observed during supine hysterosalpingography, have been resolved by the simple prone position. The high percentage (91%) of successes, without pharmacological help, recommends the routine use of this simple method in all cases of doubtful tubal obstructions.

A new catheter for peritoneal dialysis (two years of experience with Valli catheter).

The authors analyze the experience of more than 2 yrs of peritoneal dialysis with a new type of catheter. The catheter proposed allows higher flow rates and the maximum outflow of fluid even if malpositioned. The possibility of migration of the catheter is also reduced.

[Oropharyngeal lymphoid tissue as a bursa-equivalent structure: embryological and clinical considerations].

If we examine with an ontogenetic viewpoint the tissues giving origin to both thymus and avian bursa of Fabricius, we can't ignore that they are primary lymphoid organs connected to areas of ecto-entodermic junctions. They have a strong development in the embryonic life while tending to regress in the adult. The analysis of the organogenesis clarifies this affirmation.

[Odontostomatogenic focal disease; embryologic and clinical causes of autoimmune pathogenesis].

The autoimmune pathogenesis of the focal odontostomatogenous disease is investigated and emphasis is laid on the different keys of interpretation: at embryologic, clinic and immunologic level. A special attention is paid to the primary meaning of structured or non structured lymphoid tissue of oropharynx, on account of embryologic identity with thymus and bursa of Fabricius, differentiating into sectors of ecto-entodermic stratification. The clinical evidence of the bursa-equivalent significance of Waldeyer ring, appears to lie in the ascertainment of the tonsillar atrophy in course of agammaglobulinaemia of Bruton type.

Pancreatic endocrine response to the first feed in term newborn infants.

Blood glucose, insulin, C-peptide and glucagon were evaluated in 36 newborn term infants at birth, and before and 60 min after the first feed during the first day of life. Under basal conditions glycaemia diminished during the first day of life and glucagon increased, while insulin and C-peptide did not show any variation. The C-peptide: insulin molar ratio was higher in the newborn than in adults because of the longer half-life of C-peptide, probably due to reduced renal function in the neonatal period.
