[Intraoperative microbiological monitoring in abdominal aortic aneurysms in elective surgery. A review of the literature and the authors' personal experience].

Thirty-one patients, ranging in age from 57 to 78 years (mean 66), with the exclusion of cases with doubtful possible results, underwent abdominal aortic aneurysmectomy for asymptomatic AAA and had cultures from the aneurysmal wall and endovascular thrombus to identify possible microbiological source of future graft infection; 5 (16%) of 31 cultures yielded bacterial growth and the most common organism isolated was staphylococcus epidermidis. During an average follow-up of 15.4 months no graft infection was noted in patients with positive or negative aortic cultured. A literature review stresses the same disparity between positive cultures obtained at the aneurysmectomy and subsequent low graft-infection rate. It is concluded that the aneurysm wall itself does not represent an important source of early or late graft infection and it's suggested that the bacterial presence both in the wall and thrombus could be explained by an exogenous contamination at the operation time.

[Incidence of aortic aneurysms in Piedmont].

A retrospective clinico-epidemiological study of the incidence of all arteriopathy hospitalization in the Region of Piemonte over a twelve year period (1976-1987) has been performed: among all the cases, patients affected by aortic aneurysm show an average of hospitalization of 0.8 cases per 24 hours. The prevalence of the sex has been pointed out for males (75.5% versus 24.3% of females): the men showed a higher rate independently from the age. The most involved age groups are for population between 70 and 74 years, but, from 1976 up to 1987 we have observed a more homogeneous distribution than in the first considered cases when it was mainly for patients aged more than 70 years. We have to stress a curious and not under standable datum regarding the kind of therapy: patients were treated medically in 69.4% of cases, while surgery was carried out only in 27.9%, but, fortunately, since 1976, we have noticed a continuous increase of surgery up to 40% in 1987. Hospitalizations have regarded the wards of Internal medicine in 24% of cases, while both General Surgery and Vascular Surgery showed rates of 23% and 25%. The average hospitalization time has been lower if compared to that of all the arteriopathies: 14.4 days versus 22.5. Furthermore we have to point out a decrease in average days of hospitalization for aneurysms of the aorta and a decrease in the costs for this pathology. Mortality is still high, also if referred to the non-operated patients: in fact the mean is 25.5% with a low rate of necropsies (mean 29%).

[Results of electrostimulation of the spinal cord in Raynaud's disease and syndrome].

Out of 1,048 Raynaud patients followed for 10 years, only 7.48% underwent surgery. This fact also results from the recent utilization of high-level epidural spinal stimulation, which we perform first, before surgery, in all "critical" Raynaud patients. We treated 40 Raynaud patients with SCS and the results were always positive: excellent in 18, good in 6 and moderate in 6. Various modes of stimulation were used (continuous, intermittent, cyclical). The results were found to be better in Raynaud's disease, and to depend on the level of stimulation (excellent at T1), and on duration of the disease (clinical history of less than five years). Regular monitoring was carried out both clinically and with noninvasive and hemorheological tests. SCS appears to act like cervicothoracic surgical sympathectomy, but in contrast to the latter, it does not inhibit perspiration. Its mechanism in therefore different but the data is as yet insufficient to allow for more than personal hypotheses.

[Bandage of the common femoral artery after intervention of disobliteration or aneurysmectomy (considerations on surgical technic apropos of 4 cases)].

The Authors refer their surgical experience in those particular cases in which, after performing an aneurysmectomy or an endarterectomy of common femoral artery, the residual arterial wall appears too thin and weakened. In these not very rare cases, can be indicated, as an additional and prudent manoeuver in order to avoid a possible evolution towards suture disruption or pseudoaneurysm formation, the wrapping or banding of the endarterectomized tract of artery by the mean of dacron prosthesis, sutured around the artery longitudinally. This simple technique, performed in 4 patients, appears easy and safe to perform, offering the advantage to guarantee a biological arterial lumen.

[Clinical studies on peripheral arteriosclerotic lesions in the Piedmont region].

The assistance of the Piedmont Region calculation centre was obtained in the evaluation and detailed examination of data on all patients admitted to hospitals in the Region for peripheral atherosclerotic arteriopathy during a three-year period. Age, sex, site of lesion, occupation, geographical distribution, and type of treatment employed were all analysed statistically. A difference between age categories in relation to sex was noted for incidence and site of lesions, while occupation was not correlated to the clinical progress of the disease. Regional incidence (for all Piedmont local health units) was both above and below the general average in some areas. It also appeared that the greatest incidence lay along the Alps.

[Clinico-epidemiological study of patients with phlebolymphatic diseases admitted to the hospitals of the Piedmont region 1976-1979. I. Analysis of all phlebolymphatic diseases].

In conjunction with the University Calculation Centre and the Piedmont Region, a computerised study was made of all patients (31,514 cases) admitted to Piedmont hospitals for phlebopathy and peripheral lymphopathy, including pulmonary embolism, in the period 1976-79. An account is given of the method used, the material, and the statistical technique. An 18.9% prevalence of women was noted. Occupation, age category, type of pathology, and treatment adopted were assessed for phlebopathies in toto and for each type. The data for each public health unit, divided by age category, were correlated with the general cases for the Region and those for each unit. In this way, it was possible to determine the incidence of phlebopathies in each unit and over the Region as a whole in relation to age. A map of the Region showing areas of higher, lower, and not significantly different from the regional mean hospitalisation (i.e. phlebopathy) was prepared. The significance of the different incidences in the several units is discussed in relation to their populations, geographical location, raye of migration, and types of occupational activity.

[Clinico-epidemiological study of patients with phlebolymphatic diseases admitted to the hospitals of the Piedmont region 1976-1979. II. Analysis of lymphatic diseases and pulmonary embolism].

The second part of this research project looks at two very different pathologies. Pulmonary embolisms are usually emergency admissions, while lymphopathies, and this may well be an incorrect term, usually receive outpatient treatment and are only hospitalised in cases of serious incapacitation. Whereas lymphopathies were so few as to prevent any conclusions being drawn, regional admissions of pulmonary embolism occur every 28 hours and 44 minutes i.e. about 1 case per day. No particular relation between the distribution of pulmonary embolism and geographical area, level of industrialisation or migration was discovered. On the contrary there are few areas with higher figures than the expected regional average and these may be attributed to better medical organisation. Finally it should be emphasised that while cases of pulmonary embolism increase with age, the rise is less substantial than might have been expected.

[Clinico-epidemiologic study of patients with phlebolymphatic diseases admitted to the hospitals of the Piedmont region 1976-1979. III. Analysis of varicose disease].

With the aid of the University and Piedmont Region Computer Centre all cases of varicose admitted to Piedmontese hospitals between 1976 and 1979 were examined. One admission every 1 hour 35 minutes is the regional average. In terms of age there is a numerical prevalence (8526 cases) of the under forty-fives, while in percentage terms, admissions appear to increase in proportion to age. Admissions in age groups to all the individual clinics were correlated with a view to the evaluation of any variations from the regional average, without incidentally confirming these figures. Detailed statistical analysis was employed to correlate the study.

[Clinico-epidemiological study of patients with phlebolymphatic diseases admitted to the hospitals of the Piedmont region 1976-1979. IV. Analysis of thrombophlebitis].

In the 1976-79 period, 8040 cases of thrombophlebitis, equivalent to 0.17% of the population, were admitted to Piedmontese hospitals, an average of 1 admission every 4 hours and 3 minutes. The present study revealed a numerical and percentage increase with increasing age. The figures per age group from each individual clinic revealed two large areas in the East and South West of the Region where phlebitis cases were numerically lower than the regional average. In other areas figures were higher than estimated, while still others produced statistically insignificant figures. An interpretation of these results is attempted.

[Study of 357 cases of phlebitis of the lower extremities in 2 inter-regional samplings. I. Methods, epidemiological data and analysis of etiopathogenetic elements].

Using a specially designed record card, 357 cases of superficial and deep thrombophlebitis and phlebothrombosis of the lower extremities have been investigated. Of these 261 were observed in Piedmont and 96 in the Trentino region. A comparative study of aetiopathogenetic data in the two regions was made possible by means of punched cards and subsequent computer processing. The study was completed by statistical analysis. Apart from the region of birth and residence, sex (prevalently female) and age which in both samples mainly affects subjects aged between 30 and 45, the type of working activity was considered in relation to sex and age, frequency of absenteeism (higher in Piedmont), family history of venous disease, incidence of orthostatism, the use of contraceptive pills, the period in which the first clinical signs occurred with considerable diversity between the two regions, traumas (more frequent in Piedmont) and the incidence of the different causes which was vastly different in the two samples, were assessed. On the basis of the comparative data obtained, an interpretation of the real significance of the results is attempted, reference also being made to the type of population under examination, the Piedmontese being considered of mixed strain and the Trentino pure.

[Study of 357 cases of phlebitis of the lower extremities in 2 inter-regional samplings. II. Clinical and diagnostic data and therapeutic conclusions].

In Piedmont, the incidence of superficial and deep forms is the same percentage-wise. In the Trento area, however, deep forms are more common, though no significant differences can be discerned with respect to the side affected, the site (other than that related to the type of phlebitis), or the symptoms. At least one complication was noted in 241-261 and 27-96 cases in Piedmont and Trento respectively. The treatment initially employed proved inadequate. The risks involved are known solely with respect to patients with complications. The resort to surgical management was much more frequent in the Trento region. An attempt is made to evaluate the risk factors associated with thrombophlebitis of the lower limbs, and the measure of agreement between the aetiopathogenetic, clinical and therapeutic data obtained for the two regions.

[Clinico-experimental studies of the diagnostic value of plate thermography in the detection of thyroid cold nodules].

Thermography was employed in addition to scintiscanning in the preoperative diagnosis of 87 surgically treated cold thyroid nodes. A new thermographic method was used. Comparison with the scanning and clinical data and the histological finding showed it to be useful, so that its routine employment has been principally in the investigation of cold nodes in addition to hyperfunctioning nodes. The results obtained are of particular value, since they enable a resonably reliable differential diagnosis to be made of benign and malignant forms prior to surgery.

[Appendectomy and colo-rectal carcinoma. Clinico-statistical and experimental studies].

A clinico-statistical investigation has been carried out with a view to establishing whether or not there is any correlation between appendicectomy and onset of colorectal cancer. The analysis showed that the frequencies of appendicectomy in the sample studied and in the control sample were not statistically different. On the other hand, it was observed that in patients suffering from colorectal carcinoma, the age at which appendicectomy was performed is is greater than in control subjects, with a constant mean interval in males and females (17 years). Experimental research on appendicectomized rats confirmed that the incidence of clinically induced tumours is no greater than that observed in control animals.
