[Method of biopsy and ultrastructural study of the parathyroid gland in patients with primary hyperparathyroidism].

The authors suggest a new method of biopsy of a seemingly normal human parathyroid gland during surgery for parathyroid adenoma. Such a method provides adequate surgical specimen to rule out a likely diffuse hyperplastic disease associated with the parathyroid adenoma, and for the ultrastructural study of the gland, without any risk of postoperative complication. In all patients, ultrastructural examination showed an abnormal cell population and signs of glandular atrophy as a consequence of the high level of serum calcium due to hormonal hyperfunction of the parathyroid adenoma.

A new classification of varicose veins to compare various surgical strategies.

Considering the presupposition that chronic venous insufficiency (CVI) and varicose veins classifications are extremely difficult, and that none of those presently in use are sufficiently complete, the authors propose the classification of the haemodynamic venous disease (HVD) and of the varicose veins from the clinical, anatomotopographical, etiopathogenetical and haemodynamical point-of-view. This type of classification allows us to closely follow the disease's evolution, to distinguish the benign forms from the more aggressive ones, and to evaluate the results of the medical, surgical and schlerotherapical treatments, from the efficiently, functional, instrumental and aesthetically point-of-view.

[Cervical neurinomas. (Considerations in five cases operated in Day-Surgery)].

We report the experiment of five cases of neurinoma observed in the division of Day Surgery of the Third Surgery Clinic, operating in the Hematology Institute of University of Studies "La Sapienza" in Rome. The problems of the diagnosis of this neoplasia has been faced, though it is commonly unknown or confused with other cervical especially lymphonodules tumefactions, from which it is almost impossible to distinguish before the operation. In the period of six years on 775 cases of cervical neoformations have been operated only 5 patients bearers of neuromi; two originated from vago cervicale (right and left), one from simpatico cervicale on the left, another from the left spinal accessory and the last from the secondary medial trunk of the left brachial plexus. All the patients have been operated in Day-Surgery anaesthesia, locoregional and with calming of spontaneous breath. One case, that originated from the secondary medial trunk of the left brachial plexus, has been operated with microsurgical technique. On all the cases has been done a subcapsular exeresis to preserve nervous continuity. No post operating complications have been recorded; all the patients discharged in the evening. The diagnosis about the nature is left to the final histological test on the operating piece. The surgical removal remains even today the elective treatment able to exclude probable relapses and potential malignant transformation of these tumours.

[Heterotopic heart transplantation in the rat: a preliminary study].

The aims of this study are to settle and verify how trustful is the heterotopic transplantation of the heart in an experimental model utilizing the original technique of Abbott modified by Ono and Lindsey distinguishing from it for the administration of the anaesthesia and the preservation of the organ. In this type of operation is necessary to realize only two micro-surgical vascular anastomosis that represent the basis of any other micro-surgical operation of organ's transplantation in the rat. There have been used 30 rats of the Wistar stock of male sex and weighing about 200-300 grs. both as donor and as receiving. The anaesthesia consisted in the administration of methoxyflourane by inhalation during the operation. The heart is kept in a container with Stanford solution on ice. The 77% of the cases (23 on 30) have been successful, even considering the ischaemic damage that has been evaluated examining the cardiac beat and the color of the organ. The study of Ono and Lindsey gave as result the success of the operation on 91% of cases (147 on 161 operated), compared to the result obtained by us, on a smaller number of cases (77% of success on 30 operated rats) permits to consider this experimental model to be utilizable even for further more complex studies.
