The authors reviewed their experience on 94 cases of patients suffering from scrotum diseases. This study was carried out either by means of grey-scale or real-time ultrasonography. They consider ecotomography to be an essential diagnostic aid in the clinical investigation of patients affected by this pathology, being a non invasive method and characterized by very high reliability.
A case of arterial embolization of a Beall mitral prosthesis disc (model 104) 5 1/2 years after implantation is presented. The patient was referred to use 3 days after the onset of acute symptoms and was immediately operated upon in pulmonary edema and cardiogenic shock. The migrated disc was removed from the abdominal aorta 26 days later, showing marked signs of wear. The postoperative course was complicated and the patient made a slow recovery. It is suggested that patients with models 103 and 104 Beall mitral prostheses be followed very closely and that electric valve substitution should be considered when first signs of prosthetic attrition are noted.
In this work we have again examined a sample of 500 attempted suicides which took place in Parma between September 1971 and January 1976. We have made a distinction between the various types--those who tried only once and those who repeated their attempts, and have also taken into consideration other factors--sex, marital status, family background, level of education, financial position, as well as the method of the attempted suicide and the mental condition of the patient when under observation. The main points to emerge were: a) there was a much higher rate of mental illness among the patients who had repeated their attempts, (66,6%), in comparison to those who had tried only once (19,5%). b) while there was already a high proprotion of females who made one attempt (74%), the rate rose even higher so with those who repeated their attempts (88,8%).

The endometrioid-like variant of ovarian yolk sac tumor is a rare neoplasm composed partially or completely of glandular tissue resembling endometrioid carcinoma, but identifiable histologically and immunohistochemically as an extraembryonic endodermally differentiated germ cell tumor. Only nine examples of this neoplasm have been published previously, and none was studied by electron microscopy. One of these rare neoplasms, the first documented to have foci of carcinoid, has recently been observed and studied ultrastructurally. Electron microscopic observations showed that the main component of the neoplasm had glandular epithelial cells with nuclear and cytoplasmic features difficult to distinguish from the cells of Müllerian endometrioid and endometrial adenocarcinoma, but a minor component of mucinous adenocarcinoma was confirmed as intestinal by the epithelial cells having characteristic microvilli with filamentous cores and rootlets. In addition, neuroendocrine cells present in the glands and in nests were readily identified ultrastructurally by their dense-core granules. Electron microscopy may be useful in supplementing light microscopic and immunohistochemical examination of this variant of yolk sac tumor.
The synovial sarcomas constitute the 7-10% of the soft tissue malign tumors, with a preferred location in the limbs. In the head and neck a 5% of the totality are placed. We present one case of retropharyngeal synovial sarcoma and the accomplished treatment, together with a revision of the bibliography.
