The authors report their experience in clinical and instrumental diagnosis of primary varicocele, with regard to bilateral and subclinical forms. 54 patients affected by varicocele were evaluated comparing the results of clinical examination with those coming from scrotal ultrasonography and Doppler flowmetry of spermatic cords. Bilateral varicocele was found in 26 cases (48.2%); subclinical varicocele, monolateral or bilateral, was evidenced in 25 cases (46.3%). On the basis of this study clinical examination seems not to be ideal for the diagnosis of varicocele, particularly in view of a surgical or percutaneous treatment aimed at complete resolution of venous spermatic reflux.

Varicose veins present a major health problem, causing chronic leg symptoms and disability to a large segment of population. The prevalence rate in adults shows great geographical variations and increases with age. Several authors reported that most cases of primary varicose veins are due to valvular incompetence of saphenofemoral junctions. On the base of close physiopathologic and hemodynamic relationships between primary varicose veins and primary varicocele we decided to evaluate the continence of saphenofemoral junctions in a selected group of young men affected by primary varicocele. MATERIALS AND METHODS. 42 patients were included in the study. The age ranged from 13 to 55 years; the mean age was 28 years. In all cases a clinical and instrumental (ultranosography. Doppler flowmetry) diagnosis of primary varicocele was performed. Bidirectional Doppler flowmetry was used to evaluate the continence of 84 saphenofemoral junctions. RESULTS. Among the group of studied 36 (85.7%) showed a monolateral or bilateral valvular incompetence of saphenofemoral junctions; in the remaining 6 patients (14.3%) there was no evidence of valvular insufficiency. In 84 saphenofemoral junctions studied 52 (61.9%) were found incompetent, 32 to the left side and 20 to the right side. Moreover 2 patients had clinically detectable varicose veins of the lower limbs and symptoms related to chronic venous insufficiency. DISCUSSION. Varicose veins are one of the most prevalent chronic conditions in industrialized countries and places a considerable demand on the health services. Since this pathology is potentially preventable it seems very important to select within populations asymptomatic groups in which there is an increasing risk of chronic venous insufficiency and to perform a clinical and instrumental assessment, based on non invasive techniques. In the past varicose veins were related to other diseases and among them some authors suggested primary varicocele, that is due to venous spermatic reflux and/or valvular incompetence; furthermore varicocele and varicose veins are often familiar. In our 42 patients affected by varicocele only 6 (14.3%) had no Doppler flowmetry evidence of incompetence of saphenofemoral junctions and more than half (61.9%) of the junctions were found incompetent. CONCLUSIONS. In our experience we found a considerable relationship between primary varicocele and venous incompetence of saphenofemoral junctions. Perhaps these patients must be considered a group with an increasing risk to develop primary varicose veins. So we suggest that clinical examination and instrumental assessment should be performed in young men affected by varicocele, in order to obtain a prevention of chronic venous insufficiency of the lower limbs. Nevertheless this retrospective study has to be further confirmed by longterm prospective studies.

Among available drugs, omeprazole is the one that cures gastric acid secretion-related pathologies, including reflux oesophagitis which responds poorly to H2-receptor antagonists, most rapidly and efficaciously. This marked therapeutic action is thought to reflect the drug's capacity to adequately control parietal hydrochloric acid secretion. Our data suggest an omeprazole effect on human neutrophil function too. Neutrophils are more or less a constant, and often conspicuous anatomo-pathological component of the phlogistic processes associated with gastric acid secretion. A direct or indirect effect exerted by omeprazole on leukocyte function would be of great scientific-biological and therapeutic interest. Furthermore, it would contribute to marking the drug superior in terms of more rapid relief of the symptoms and range of therapeutic action.

We have explored the changes of plasma concentrations of antithrombin III and fibrinogen in patients recovering from major abdominal and cardiac surgery. In one group of patients subjected to major abdominal surgery we detected a statistically significant reduction of antithrombin III in the second and third postoperative day, followed by return to normal values in the fourth or fifth day. Fibrinogen, instead, increased to as much as 180% of the preoperative value in the first four postoperative days and reverted slowly to preoperative values between the fourth and the eighth day. In another group of patients subjected to cardiac surgery procedures utilizing the heart-lung machine, however, we found no significant reductions of antithrombin III in the early postoperative period. These results suggest the possible influence of local tissue factors affecting the plasma levels of antithrombin III differently in the two types of surgery under discussion. The patients subjected to extracorporeal circulation, on the other hand, showed a depletion of plasma fibrinogen down to less than 30 or 40% of preoperative values. This may reflect activation of coagulation processes and the considerable sequestration of fibrin at some interfaces of the heart-lung machine.
