Abstract
The increasing use of chemotherapy in association with surgery has prompted the suggestion that cancer chemotherapeutic drugs may interfere with the healing process. To test this hypothesis 30 Wistar rats were subjected to laparotomy and colonic resection and treated with 5-Fluorouracil or Mitomycin C. The bursting strength of the abdominal scars and the colonic anastomotic bursting pressure revealed some interference in the rats treated with 5-Fluorouracil (Student's t test P < 0.05) but none in the case of Mitomycin C. This preliminary study deserves to be followed up.

Abstract
BACKGROUND The need to dissect axillary nodes in patients with early breast cancer and clinically negative axilla remains controversial. The aim of the study was to assess the role of axillary radiotherapy (RT) in reducing axillary metastases in patients with early breast cancer who did not receive axillary dissection. PATIENTS AND METHODS From 1995 to 1998, 435 patients over 45 years old with breast cancer up to 1.2 cm and no palpable axillary nodes were randomized 214 to breast conservation without axillary treatment and 221 to breast conservation plus axillary RT. RESULTS After a median follow-up of 63 months, overt axillary metastases were fewer than expected: three cases in the no axillary treatment group (1.5%) and one in the RT group (0.5%). Expected cases were 43 in the no axillary treatment group and 10 in the RT group. Rates of distant metastases and local failures were low, and 5-year disease free survival was 96.0% (95% confidence interval, 94.1%-97.9%) without significant differences between the two arms. CONCLUSIONS This study suggests that occult axillary metastases might never become clinically overt and axillary dissection might be avoided in patients with small carcinomas and a clinically negative axilla. Axillary RT seems to protect the patients from axillary recurrence almost completely.

Abstract
Few series of splenic artery aneurysms (SAA) have been reported, but today asymptomatic SAA are detected with increasing frequency. Their importance lies from their potentially fatal consequences as life-threatening hemorrhage. SAA management still remains controversial as reported in this review. Our 2 patients treated with resection of the aneurysms, both located in the middle third of the splenic artery. Some authors demonstrated that when splenic artery has been ligated (or embolized) and the patients remain anatomically splenic, they may not retain any splenic function. Laparoscopic SAA ligation repair appears to be optimal and useful for aneurysms protruding from the pancreas and it is gaining interest because clinical recovery is rapid with a poor morbidity and economic and cosmetic advantages. Transcatheter embolization too offers a temporary control in urgency to stop hemorrhage and go back at later date to make much better elective operation. Endovascular interventions as percutaneous embolization has recently gained popularity: it offers a safe alternative or adjunctive therapy to traditional surgery. We hope in the future instrumentation will likely improve so that this procedure can be done percutaneously by development of prosthetic devices in the 21th century.

Abstract
The wide variety of prevalence of antimicrobial resistant Streptococcus pneumoniae in different countries confirms the importance of determining local patterns of resistance. From 1992 to 2000, we studied the pattern of antimicrobial resistance in S. pneumoniae and its evolution along the years, using 468 strains isolated in the Hospital de Niños de Córdoba. A total of 177 isolates (37.8%) were not susceptible to penicillin, with 19% intermediate and 18.8% resistant strains. High and intermediate resistance levels to cefotaxime were 4.9% and 10.9%, respectively. Decreased susceptibility to trimethoprim/sulfamethoxazole (TMS), erythromycin, chloramphenicol, and rifampin was found in 194 isolates (41.5%), 32 (6.8%), 13 (2.8%) and 3 (0.6%), respectively. No isolates resistant to vancomycin were detected. The most commonly combined resistance patterns were: penicillin/TMS (35.6%) and penicillin/TMS/cefotaxime (11.8%). This study highlights the increased rate of drug resistant S. pneumoniae during the last years, and the importance of antimicrobial resistance surveillance of adequate empirical therapy involving local and regional susceptibility patterns.

Abstract
PURPOSE To evaluate the angiogenesis in Dukes' B colon cancer. PATIENTS AND METHODS In 60 patients (age, 39-75 years), the microvessel density and the relationship between the angiogenesis and other histologic features were retrospectively evaluated. In an ongoing prospective study, 25 patients have been enrolled to determine the possible therapeutic implications of VEGF quantitative analysis. RESULTS The retrospective portion of this study confirms the prognostic value of the angiogenesis in terms of recurrences and survival. At present, no conclusions can be drawn from the prospective portion of the study.

Abstract
A study was carried out in 47 patients undergoing general surgery and elective gynecological surgery under totally endovenous general anesthesia. For this purpose, propofol and buprenorphine were used in controlled ventilation with oxygen and air, totally excluding the use of nitrous oxide and halogenate vapours. The following parameters were measured to evaluate the state and depth of anesthesia: arterial pressure (systolic, mean, diastolic), heart rate, sweating, lacrimation (Evan's PRST). The awakening from anesthesia was evaluated using Steward's test. The results of monitoring show that the method represents a valid alternative to anesthesia using inhalatory techniques. Nonetheless, the Authors underline the need for further research on the subject.

Abstract
Radical nephrectomy with initial ligation of the renal artery and removal en bloc of the perirenal fat and lumboaortic lymphadenectomy was carried out according to the technique of Robson (1969) in 10 cases at the University of Parma 1st Surgical Clinic between 1976 and 1978. The usefulness and superiority of the technique were demonstrated in this albeit small series, which included four stage I, two stage II, one stage III, and four stage IV patients, according to the classification of Flocks et al. Supplementary antiblastic and/or hormonal treatment was given, except in stage I cases. 1.4 mg/m2 Velbe i.v. (1st day) followed by 80 mg/m2 BCNU i.v. (2nd, 3rd, 4th days) was of no avail, whereas progesterone (Depot-provera 200-500 mg/day for 1-3 months) and testosterone propionate (300 mg/week) still seem to be effective. Improvements in this oncological sector, however, are geared to the outcome of radical nephrectomy.

Abstract
Personal experience and the literature are referred to in an examination of complications arising in the course of cancer of the large intestine. A personal series assembled in about 20 years is presented. It consists of 135 cases of heteroplasia, including 57 emergency admissions for complications. The surgical technique employed is described. The results show that surgical risk and post-operative mortality are lower in patients subjected to major radical surgery, as opposed to those for whom symptomatic management or simple, derivative operations are prescribed.

Abstract
Foot lymphography was performed in a selected group of 250 patients with malignant melanoma, with different sites of origin and of various stages. The overall incidence of metastases was 40%. The case material was evaluated in detail; the tumors of the inferior limb and those on different sites, e.g., vulva and abdomen, were considered separately. In the group of 188 patients with melanoma of the inferior limb, the incidence of metastases was 42%. In 51%, histologic confirmation was obtained. In the group of 62 patients with melanoma of different sites of the body, the incidence of metastases was 34% and histologic confirmation was obtained in 21 patients. The values of accuracy, sensitivity, and specificity based on the histologic confirmation of the lymphographic reports ranged from 88% to 96%. These data justify the use of lymphography in the initial diagnostic work-up and in the follow-up of these patients.

Abstract
Twelve consecutive cases of non-Hodgkin's lymphomas with initial testicular involvement have been considered in this retrospective evaluation. In 801 cases with referred for treatment to the Istituto Nazionale Tumori of Milan from 1962 to 1974 evidence of initial testicular involvement was observed in 1,4 % of cases. Of the whole group of testicular tumors treated in our Institute only 3 % were classified as non-Hodgkin's lymphomas. Six out of 12 patients with stage I (2 cases) and II (4 cases) diseases were treated with Cobalt therapy to the retroperitoneal nodes. Only one patient remained free of disease after radiotherapy. Three patients relapsed after primary irradiation and six patients classified as stage IV were treated with chemotherapy. Patients receiving combination chemotherapy had in general a better quality of response and a larger, but not significantly different, survival, compared to patients given simple agent sequential chemotherapy. Since the differential diagnosis between testicular lymphomas and seminomas may cause some difficulties and therapeutic implications are different, clinicians should be alert to this problem: in our case series testicular non-Hodgkin's lymphomas was the most frequent non-germinal tumor of the testicle.
