The Authors have studied 272 pregnancies in women above 40 years. This record was on 27.215 deliveries in ten years (1970-1979) at the Department of Obstetrics and Gynecology of the University of Parma. From 1970 to 1979 this phenomenon has decreased by 50%. The incidence of obstetric pathology has been elevated (38,87%): this percentage has been more in premature rupture of membranes, pre-eclampsia and uterine inertia. Of these 272 pregnancies, the 37,35% had pathologic cases before pregnancy: these cases were hypertension, heart troubles and diabetes. Cesarean section was elevated (38,98%), so also premature delivery (12,86%) and low birthweight (12,68%). The incidence of malformations was 10,50%. The perinatal mortality was elevated (49,05%0): the majority of this mortality was recorded before delivery.

160 cases of neoplasm of the kidney in the adult are reviewed, with regard to to-day knowledge of problems not yet resolved in the field both of diagnosis and treatment. As diagnosis is concerned, the primary role of angiography is confirmed, though the alternative and/or complementary role of ultrasounds and densitometry cannot be overlooked. As for treatment, the primary choice seems to remain surgery, in which regard a new meaning of radicality and operability is on way to develop, due to improvement of diagnostic means and, in lesser grade, of complementary treatments.

The authors, after a review of the clinical pathological aspects of the angioimmunoblastic lymphadenopathy, report a case studied by means of clinical, pathological and immunological aspects. On the basis of the results a hypothesis on the pathogenesis and treatment is postulated.

The physical examination and symptoms (vertigo, nystagmus and muscular asymmetry) of patients with typical vertigo are reviewed after a brief description of anatomic and physiologic features of the vestibular system. According to the daily clinical practice, the etiology, pathogenesis and differential diagnosis of peripheral vestibular syndromes are discussed. A review of the therapeutic approach to peripheral vertigo is presented.

By using and comparing three liver trophical substances, the authors have studied their individual effect on some alcoholic not cirrhotic liver diseases. They conclude at last that the removal of the alcoholic noxa and the action of the substances individually used cause an acceleration of recovery and a regression of the alterations of hepatic insufficiency, due to an excessive administration of alcoholic drinks. It's difficult, however, to draw some useful practical indications particularly on the choice of this or that medicament used.

The Authors explain the experience about the porcine xenograft, the results of the application of 98 bio-prostheses implanted between January 1976 and November 1979. The distribution of the implantations is: 52 mitral valve reimplantation; 16 aortic valve reimplantation, 2 tricuspid valve reimplantation, 26 xenograft were implanted with the association of another prosthesis or aorto coronary by-pass graft. The patients were selected for clinical criteria (age, sex, geographic provenance) and haemodinamic criteria. Three early embolism were checked, one lethal. The total mortality is of 9 patients: 4 patients were submitted to multiple surgical operation. The running of porcine xenograft is good on the middle term.

The distribution of normal intestinal flora changes in the different gut segments and is influenced by gastric pH, peristalsis, bactericidal activity of Immunoglobulins A (locally produced). Saprophytic bacteria prevent the growth of pathogenous microorganisms, partake in the production of vitamins (K, B group), can be responsible for the production of carcinogens and co-carcinogens by acting on bile-acids, food or drugs ingested, can affect the morphology of the intestinal mucosa. Enteroviruses are transient intestinal microorganisms, responsible for infectious disease whose highest incidence is summer and autumn, whose frequency is particularly elevated in malnourished subjects.
