Outcome of T1N0M0 breast cancer in relation to St. Gallen risk assignment criteria for adjuvant therapy.

T1N0M0 (stage I) breast cancer (BC) has been increasing in recent decades but the optimal adjuvant approach remains controversial. To assess the outcome of BC patients stratified and treated with multimodal therapies according to St. Gallen consensus meeting recommendations, we retrospectively evaluated an unselected cohort of T1N0M0 BC patients, with respect to the St. Gallen criteria. At a median follow-up of 5 years, the recurrence rate, recurrence-free survival and overall survival were 7%, 94% and 96% respectively, and 60% of relapses were locoregional. No statistically significant difference was observed between T1a,b/T1c groups, or among risk categories (high/intermediate/low). The very low rate of distant recurrences even in patients with unfavorable prognostic factors seems to support the use of adjuvant systemic therapies but better prognostic and predictive factors are strongly needed for this subset of patients.

Ischemic stroke with cardiac involvement in aortic thromboembolism.

An aortic thrombus may be detected by using transesophageal echocardiography after an embolic event. Clinical features are variable and may include cardiac and neurologic symptoms, such as the stroke. We report a case of a woman with an acute ischemic stroke, a myocardial infarction and a free floating aortic thrombus.

[Spontaneous pneumothorax caused by lung metastasis of sarcoma of the thigh]. / Pneumotorace spontaneo da metastasi polmonare di sarcoma della coscia.

Relapsing spontaneous pneumothorax can be the first manifestation of pulmonary metastases of soft tissues sarcomas. Standard imaging techniques and computed tomography may not be able to detect small malignant cystic lesion or to distinguish between them and benign bollous lesions. We report the case of a 33 year-old male who, in the past, underwent surgical treatment for a synovial sarcoma of the inferior limb. The patient was admitted to our hospital because of right spontaneous pneumothorax; both chest x-ray and CT scan didn't detect any metastatic pulmonary lesion. A few days after the discharge the patient was readmitted because of relapsed pneumothorax; high-definition CT of the chest revealed a pulmonary cystic lesion that was resected thoracoscopically. Histological examination revealed a pulmonary metastases of synovial sarcoma.

[Chest pain and acute myocardial infarction at the emergency department: diagnostic and therapeutic approaches. Experience of the San Camillo Hospital in Rome]. / Dolore toracico e infarto miocardico acuto in Pronto Soccorso: percorsi diagnostici e terapeutici. L'esperienza dell'Ospedale San Camillo di Roma.

BACKGROUND: Identification and treatment of patients with acute chest pain due to acute coronary syndrome is a common and difficult challenge for emergency physicians. The aim of this study was to establish: a) the reliability of diagnosis of acute myocardial infarction met in the emergency ward, b) the length of the patient's hospital stay with acute myocardial infarction discovered and treated in the emergency ward either with primary angioplasty or with thrombolysis. METHODS: We analyzed the data collected in the emergency ward of the San Camillo Hospital in Rome from January 1 to June 30, 2000, with patients suffering from chest pain and diagnosis after hospitalization. The reliability of diagnosis of acute myocardial infarction was calculated from the comparison of the diagnosis in the emergency ward and the diagnosis at hospital discharge. RESULTS: From January 1 to June 30, 2000, 45,810 patients have asked for help at the emergency ward; 2334 (5.1%) of these were suffering from chest pain. The diagnosis of acute myocardial infarction was done in the emergency ward in 147 cases (141 hospitalized, 4 deceased, and 2 transferred to other hospitals), equal to 65% of all those discharged with the same diagnosis in the period under examination. In 66 out of the 141 cases hospitalized (46.8%) primary angioplasty was successfully performed; in 14 (9.9%) only coronary angiography was performed (primary angioplasty unfeasible); in 22 (15.6%) thrombolysis was administered whereas in 38 cases (27.0%) other treatments were used. The average stay for the different groups turned out to be 9.8 +/- 4 days for primary angioplasty and 12.9 +/- 4 days for thrombolysis: the difference was relevant. CONCLUSIONS: The accuracy value of the diagnosis of acute myocardial infarction made in the emergency ward of our Hospital is the same as that published in the international literature and demonstrates the high level of treatment of chest pain. Furthermore, the shorter hospital stay obtained by primary angioplasty in comparison with thrombolysis seems to strengthen the already favorable cost-benefit ratio of primary angioplasty in comparison with thrombolysis.

Clinical errors in emergency medicine: experience at the emergency department of an Italian teaching hospital.

The level of commitment in the analysis of clinical errors made in the emergency department (ED) is currently focused on organization and processes rather than on individual action. Four major cases of clinical errors made in the ED of a teaching hospital were investigated. Analysis suggested that the process of clinical decision making and the overreliance on the use of patterns during the cognitive process had a major role in causing the errors, rather than factors related to procedures or organization. It appears hard to design system changes and tactics to significantly reduce the probability of making errors associated with the cognitive process involved in clinical decision making. The authors have initiated a systematic analysis of errors made during the diagnostic workup in their ED, and the rate of clinically significant errors is tracked. A file is being created with the purpose to use it for teaching and orientation of all new staff.

[Metastatic breast cancer: what are the objectives?]. / Il carcinoma metastatico della mammella: quali obiettivi?

UNLABELLED: The medical approach to the treatment of metastatic breast cancer has changed in the last decade since the introduction of new drugs that demonstrate high activity and better tolerability profiles. The hormonal treatment, usually considered the first choice therapy for ER-positive metastatic breast cancer patients, has seen several improvements with the discovery of new selective aromatase-inhibitor agents and pure antiestrogens. New aromatase-inhibitors have shown higher activity and fewer side effects compared to megestrol acetate in second line treatment. The first line treatment has unchanged so far, but in the next future is possible that different agents, with lower toxicity, will replace tamoxifen since studies comparing this agent with pure antiestrogens or selective aromatase-inhibitors are ongoing. These new drugs would provide a better palliation of metastatic breast cancer in terms of higher clinical benefit, tolerability and quality of life. Chemotherapy is often used in ER-negative patients or in aggressive hormone refractory disease. Randomized trials have demonstrated that anthracyclin-containing regimens were more effective than combinations without anthracyclines. New cytotoxic drugs with high activity, such as taxanes (paclitaxel and docetaxel), vinorelbine, gemcitabine and capecitabine, have been introduced. Compared with older therapies, improved objective response rates and/or improved duration of response have been reported with these newer agents alone or in combination with other drugs. However, no clear improvement of overall survival has been shown so far. Taxanos alone or in combination are today considered the second line treatment of choice and studies are assessing the value of a taxane-anthracycline containing regimen in first line treatment. Some new agents (vinorelbine) showed, alone or in combination, an interesting cost-effectiveness ratio with similar or higher "quality adjusted progression free survival" if compared to taxanes. Promising are also the results of agents that own low toxicity with comparable efficacy such as liposomal anthracycline. Attempts to improve overall survival with increased dose intensity or with high dose chemotherapy are disappointing. CONCLUSIONS: Since the goal of treatment of metastatic breast cancer is disease control rather than disease skill i.e. palliation of patients with complications of progressive cancer, the new agents have brought significant improvements (higher response rates, median time to progression, cost benefit and better tolerability). Future progresses for this disease, hopefully even in overall survival, will depend on the introduction of new therapies such as immunotherapy, inhibition of intracellular signaling, interference with tumor angiogenesis, gene-therapy and the development of vaccines.

[Early discharge project appropriate for the healthy newborn]. / Progetto di dimissione precoce appropriata del neonato sano.

Recently the stay in the hospital of the pueperae and of their newborns has progressively been shortened in several Countries. A lot of reports evaluating the risks of early discharges have not shown any significant differences in the hospital readmission rates between newborn early discharged and case-controls. This phenomenon is occurring also in Italy and the early discharge after the delivery is one of the aims of the "Percorso-Nascita" in the National Health Program of 1998-2000. Since three years ago, in the Nursery of the Department of Neonatal Medicine of University of Parma we have been discharging the newborns at term in the second day of life, choosing the healthy newborns in agreement with the obstetricians. The increment of the early discharges has happened in our Department after realizing that those did not create an increment of the hospital admissions in the neonatal period. Since January 2000 in Parma the project of appropriate discharge named "around the cradle" derived from the cooperation between hospitals and territory is working. This project consists of a continuous essistential support for mothers and children throughout an organic integration between hospital and territory. The women that take part to this project have the opportunity to be discharged from the hospital between the 44 and the 56 hours after the physiological delivery, being followed at home by the local obstetrician and paediatrician. The project is divided into three parts. The first part, pre-partum, is based on the information that is delivered to all the pregnant women that are eligible; the second part, the hospital phase, implies the usual and routinary care to the pueperae and their newborns as well as the clinical neonatal and obstetrical evaluation that allows to select our cohort. In the latter phase, extra-hospital, the local paediatrician take care of the newborn and start examining him/her within 72 hours after the discharge, while the home assistance of the local obstetrician will be within 48 hours. After initial difficulties, the organization of this project is quite efficient with a constant increment of attending requests to our project by the patients. Of course this is an organizative model quite complex that needs to verify process, efficiency and results, but anyway it sees the cooperation among many professionists of different specialities: neonatologists, paediatricians, obstetricians, practitioners, all working together for a common programme.

[Role of cardiac first aid in a level-II Emergency Department]. / Ruolo del Pronto Soccorso Cardiologico in un Dipartimento di Emergenza di II livello.

We report our experience in the organization and management of a Cardiac First Aid Unit (CFAU) which was developed according to the guidelines of the National Hospital Cardiologists Association as a part of a General Emergency Department. The CFAU is a 24 hour service directed by a Senior Cardiologist. The medical facilities are two monitored beds for short-term observation (cardio-pulmonary resuscitation instruments, echocardiograph, endoesophageal pacing for overdrive). The main goals of CFAU are the treatment of cardiac emergencies (acute myocardial infarction, pulmonary oedema, threatening arrhythmias, etc.) and the screening of patients presenting with chest pain or symptoms suggesting cardio-vascular involvement. In one year, there were 1700 admissions to the CFAU (3.7% of the total Medical Emergencies). The frequency of hospital admissions was 81% and coronary heart disease accounted for 38.3%. A sample of 100 consecutive patients with acute myocardial infarction admitted in the period October-November 1996 was examined to explore the impact of a CFAU on in-hospital delay in the application of thrombolysis. Thirty-nine patients were treated with thrombolysis, 15 in CFAU and 24 in Coronary Care Unit (CCU). The mean in-hospital delay to thrombolysis was 30 +/- 14 minutes for those treated in CFAU and 55 +/- 12 minutes for those treated in CCU (p < 0.0004). In a second sample of 100 consecutive patients with undetermined chest pain, by means of our protocol of short observation we identified 22 cases of acute myocardial infarction (AMI), 8 cases of angina pectoris, 18 various cardiac causes, 30 non-cardiac causes, 22 absent disease. ECG was obtained in all 100 pts, cardiac enzymes in 74, echocardiogram and chest X-ray in 48, ST monitoring in 26. In no case was diagnosed AMI after discharge. Cardiac First Aid Unit, as designed in our Hospital, suits the needs of a level II Emergency Department. It is a useful tool to shorten in-hospital delay to thrombolysis and to screen chest pain with nearly complete safety.

[Epidemiology of severe thoracic trauma at a multiregional urban hospital. Analysis of 5 years]. / Epidemiologia del trauma toracico grave in un Ospedale urbano multizonale. Analisi di 5 anni.

The authors re-examined 198 cases of severe chest trauma presented in their hospital in 1983-1987. They analyse the clinical conditions, the diagnostic and therapeutic procedures, the results and complications and evaluate each patient according to the ISS code to compare them with the literature data, for the dead patients they classify the lesions according to the autoptic examinations. They confirm in this the validity of the ISS that can be well correlated with: mortality, length of survival and length of hospitalisation, they indicate important prognostic factors such as: age, association with extra thoracic lesions and number of intrathoracic lesions. Plotting the mortality in function of the time, they stress the need for an expert team in the first hours after trauma to manage such patients.

A summary of the Milan experience with multimodality therapies in patients with small cell lung cancer: attempts to improve long-term outcome.

From February 1985 to June 1993, 173 consecutive, previously untreated patients with small cell lung cancer received individualized treatment tailored to disease extent. Almost all patients (14 of 16) with stage I and II disease and 30 patients with operable stage III disease were submitted to surgery preceded or followed by chemotherapy. Chest irradiation and prophylactic brain radiotherapy (in complete responders) were administered at the end of treatment in 42 of 44 cases. Patients with inoperable limited disease received chemotherapy followed by radiotherapy in 67 of 71 cases, while chemotherapy alone or followed by radiotherapy in sites of either initially bulky or residual disease was administered to 58 patients with extensive disease. The overall response rate was 77% (complete response, 45%; partial response, 32%). Complete responses were documented more frequently in limited disease than in extensive disease (57% v 22%; P < .001). The 2- and 5-year freedom from progression rates (24% and 16%, respectively), as well as overall survival rates (31% and 16%, respectively) were significantly affected by disease extent. No patient with extensive disease was progression free and alive at 2 years, while more than half of stage I and II patients were disease free and alive at 5 years. This retrospective analysis performed on a large number of consecutive, nonrandomized patients suggests that, at least in patients with limited disease, it is possible to achieve favorable long-term results using treatment tailored to disease extent. Nonetheless, the disappointing results commonly achieved in the treatment of small cell lung cancer strongly support the need for either prospective, randomized studies to confirm recently reported improved results or new pilot studies with investigation of entirely innovative approaches.

[Surgical therapy of perforated duodenal ulcers: suture versus highly selective vagotomy. Immediate and remote results (case series from 1978 to 1990)]. / Terapia chirurgica delle ulcere duodenali perforate: rafia versus vagotomia superselettiva. Risultati immediati e a distanza (casistica dal 1978 al 1990).

The aim of this study was to compare the results of high selective vagotomy and simple suture in the treatment of perforated duodenal ulcer. Among 150 patients admitted in our institute from 1978 to 1990, 96 were treated with simple suture while 54 underwent high-selective vagotomy (42 with pyloroplasty). In our study with high-selective vagotomy we had no surgical mortality and low morbidity. The overall clinical results according to the Visick evaluation, were recorded as excellent or good, in 90.9% cases in the group of patients treated with high-selective vagotomy versus 40% in the group with simple suture, after a similar period of follow-up. The recurrence of ulcers after high-selective vagotomy was of 6%, compared with 32.6% in simple suture patients. The results of high-selective vagotomy performed for perforated duodenal ulcers were compared with those of a group of duodenal ulcers not complicated treated with high-selective vagotomy too; the better results of this last group may be due to higher technical difficulties in presence of peritonitis. High selective vagotomy is therefore a safe procedure in the management of perforated duodenal ulcer, and moreover obtains good long-term results in the control of peptic disease.

[Heparin and lipoprotein(a). Observations during hemodialysis]. / Eparina e lipoproteina(a). Osservazioni in corso di emodialisi.

The effect of heparin (bolus e.v. 5.000 I.U.) on blood levels of Lp(a) and other lipids (triglycerides, -HDL, -LDL and total cholesterol, apo A1, apo B100 and apo A1/apo B100) was studied in 15 patients (8 M and 7 F) with chronic renal failure during hemodialysis. Statistically significant reductions of the basal values were found for Lp(a) and the other lipids in the blood taken before the beginning of dialysis, 30 min' after the heparin bolus. The analysis of third blood sample (at the end of the hemodialysis, one hour after the end of the heparin maintenance infusion) showed a rise of HDL and LDL-lipoproteins over the basal values clearly in relation to reduced heparin and plasmatic fraction of the blood. The values of Lp(a) had not so high increase as consequence of more elevated affinity with heparin and of a possible enhanced metabolic rate via lipoprotein lipase. The authors, in agreement with similar changes of Lp(a) and other lipids previously observed in patients with coronary diseases during bypass surgery in extracorporeal circulation or angioplasty, (interventions requiring generous heparin treatment), believe to have now sufficient data for attributing heparin a causal role for the above mentioned effects. The authors stress the needing of other studies better understand the action to mechanisms of heparin and to evaluate possible future clinical applications of this new interesting Lp(a)-clearing effect.

Chronic effects of subcutaneous interleukin-2 therapy on soluble interleukin-2 receptors in advanced small cell lung cancer.

The increase in IL-2 receptor serum levels is one of the most typical changes in immune parameters during IL-2 cancer immunotherapy. To better define the effects of prolonged IL-2 injection on SIL-2R levels, we evaluated 7 advanced small cell lung cancer patients who received IL-2 subcutaneously at a daily dose of 9 x 10(6) IU/m2/12h for two days followed by 3 x 10(6) IU/m2/12h for 18 days (5 days/week for 4 weeks). Moreover, four patients were also evaluated during the second IL-2 cycle. Venous blood samples were drawn before and at weekly intervals during IL-2 therapy. Mean SIL-2R serum levels rapidly increased with the start of IL-2 injection, and they were significantly higher than the baseline levels throughout the immunotherapy cycle. The increase in mean SIL-2R levels was higher in patients with progressive disease than in those with response or stable disease, but the difference was not significant. Finally, the increase in mean SIL-2R concentrations during the second IL-2 cycle was not significantly different from that seen during the first one. The present study confirms that IL-2 administration determines an evident increase in SIL-2R levels; moreover, it would demonstrate that re-exposure to IL-2 after a rest period does not induce a more pronounced SIL-2R release.

[Heller's extramucosal cardiomyotomy under endoscopic control. The long-term results]. / Cardiomiotomia extramucosa secondo Heller sotto controllo endoscopico. Risultati a distanza.

Twenty-five patients underwent Heller cardiomyotomy with Nissen fundoplication, made through an abdominal incision under endoscopic control. Long term results were evaluated according to clinical, radiological, manometric and 24-hour esophageal pH-metric studies. Clinical results were excellent in 44% of the patients, good in 40%, fair in 4% and bad in 12%. The four unsatisfactory results are due to recurrence of dysphagia in one case and to appearance of GER in the others. Postoperative X-ray controls and manometric tests showed a significative decrease in the esophageal diameter, in resting and post swallowing LES and esophageal body pressure. The 24-hour pH test showed an abnormal percentage of time with pH less than 4 in two patients, and a direct connection with clinical and endoscopic results. Endoscopic control of myotomy allows us to define precisely the extension of the functional stenosis and to eliminate completely the dysphagia. In the postoperative evaluation the 24-hour pH monitoring allows an early identification of GER, and the prevention of possible complications even in the absence of any clinical sign.

[Comparison of mechanical and manual anastomoses in emergency gastric resection]. / Confronto fra anastomosi meccaniche e manuali nella resezione gastrica in urgenza.

Hundred and twenty-one patients underwent emergency subtotal gastrectomy for complications related to peptic ulcer (86) and malignant diseases (35). According to the type of anastomosis performed (manual or mechanical) patients were divided into two groups: 81 with hand-sutured anastomoses (double layer) and 40 with stapled anastomoses. The latter were more commonly used in the Roux-en-Y reconstruction and Billroth 1 gastrectomy. Median operating time (192' versus 190'), hospital stay (15.2 versus 13.5 days), postoperative complications (38% versus 32.5%) and anastomotic or duodenal stump leakage (7.4% versus 5%) showed no significant difference between groups. Therefore, in emergency subtotal gastrectomy mechanical anastomoses allow to obtain results comparable to the more used manual ones.
