Background and Aim: Appropriate end of life (EOL) management in Internal Medicine wards is challanging. The aim of this study was to analyze the burden of an educational program on EOL management in a Internal Medicine ward. Materials and methods: We retrospectively analysed characteristics and management of patients consecutively died in an italian Internal Medicine ward along one year. We compared demographic, co-morbidity, pharmacological treatment in the last 48-hours of life and procedures during hospital stay in patients died six months before and after an educational program on palliative cares and EOL management addressed to a team of physicians and nurses., Results: Study population was composed by 354 patients (190 females), with mean age ± DS 83.5 ± 10.6 years, one half admitted after the educational program. Eighty-four percent of deaths was exepected in the last 48 hours before exitus. Demographic characteristics and causes of hospitalization were not different before and after educational program. After the educational program the sharing of palliative care program with patient, relatives and/or caregivers (97.7% vs 85.8%, p=0.0001) and written order to withdrawal vital parameters relevation (39.5% vs 22%, p=0.0005) significantly increased, while difference in pharmacological classes prescribed in the last 48 hours of life was not find. Blood (54.8% vs 67.2%, p=0.0219) and arterial gas analysis (28.8% vs 39.5%, p=0.0435) samples in the last 48 hours of life were significantly reduced. Radiological and/or endoscopic examinations, red cells or platelets transfusion were reduced and palliative therapy was increased, despite difference between the two periods was not statistically significant., Conclusion: Educational program in Internal Medicine wards aimed to improve skills could contribute to make EOL management more appropriate and patient-oriented and it should be strongly encour-aged.

Objective: Perioperative myocardial ischemia is less pronounced in off-pump coronary artery bypass (OPCAB) compared to on-pump coronary artery bypass; however, the threshold over which the postoperative release of cardiac troponin I (cTnI) release and creatine kinase-MB (CK-MB) after OPCAB should be considered clinically relevant is unknown. The study was designated to evaluate if perioperative myocardial damage, measured by means of postoperative release of cTnI and CK-MB, has an influence on short- and mid-term outcome after OPCAB operations., Methods: Two hundred and sixty-one unselected patients undergoing OPCAB had cTnI and CK-MB measured preoperatively and nine times postoperatively. Postoperative peak values were evaluated and the 80th percentiles were used to segregate the population into two groups for each marker. The following cut-offs were used: 7.1 ng/dl for cTnI peak and 36.3 ng/dl for CK-MB peak., Results: Patients with cTnI>7.1 ng/ml (n=51) and CK-MB>36.3 ng/ml (n=48) had a longer mechanical ventilation and ICU length of stay. Nevertheless, hospital mortality did not differ between groups. Survival after 3 years was 92.8+/-2.3% and 81.8+/-6.2 for patients with postoperative cTnI peak7.1 ng/ml, respectively (p=0.003). It was 93+/-2.2% and 80+/-6.8% for patients with CK-MB36.3 ng/ml, respectively (p=0.005). Adjusted hazard ratios for mid-term mortality were HR 2.7 (CI 1-7.6), p=0.05 for cTnI>7.1 ng/dl and HR 3.1 (CI 1-9.1), p=0.04 for CK-MB>36.3 ng/ml., Conclusion: Perioperative myocardial damage should not be considered an innocuous event following OPCAB operations since the survival rate over 3 years is significantly worse in patients with the highest postoperative peak release of cTnI and CK-MB.

A morbidly obese patient is reported who underwent insertion of a BioEnterics Intragastric Balloon (BIB) as a pre-surgical procedure (ie. prior to restrictive gastric banding). While carrying the BIB, the patient suffered an episode of severe supraventricular tachyarrhythmia (atrial fibrillation). Although such an event is not definitely correlated to the BIB, the episode led us to modify the pre-treatment protocol, introducing dynamic Holter ECG into the work-up investigations and excluding subjects with a pathological cardiac rhythm.

Use of mean-field annealing theory is proposed for solving the phase-unwrapping (PU) problem. PU is formulated as a constrained optimization problem for the field of integer corrections to be added to the wrapped gradient field. A deterministic algorithm is described to provide an approximation of the average of the correction field over the global minima of the cost function. The proposed algorithm can be applied for any choice of the cost function. Using a cost function based on second-order differences, we obtain results close to those from simulated annealing and spend less computational time.

Sarcomas of the soft tissue constitute a fairly rare group of neoplasms localized mainly at the level of the extremities. Apart from clinical and semeiotic investigations, diagnosis is based on imaging techniques. Among these (ultrasound, CT, NMR and angiography), all of which are helpful in diagnosis, NMR seems to provide the most complete data and sensitivity and specificity. In fact, it has greater specificity than ultrasound or CT as regards identification of any infiltration of the muscle or deep interstitial tissues and can also contribute information on the nature of the sarcoma, as it provides high definition of the structural composition of the tissues. Angiography remains important as a preoperative guide to the surgical approach. Surgery is the treatment of choice, although in recent years it has been integrated with radio or chemotherapy. Thanks to the progress in treatment constituted by combination treatments there has been a dramatic reduction in the need for amputations, compartmental excision and disinsertion of muscle groups. We report the case of a patient with fibrosarcoma of the thigh and discuss the various imaging techniques and different approaches to the treatment of these neoplasms.

The authors have evaluated the efficacy of short term treatment with an imipenem-cilastatin combination in a selected group of 72 patients undergoing implant or substitution of a pacemaker and with associated pathology potentially increasing the risk of infection. After 30 months' follow-up, the authors underline the efficacy and advantages of this treatment.

According to a recent national survey, 387 patients were treated by permanent pacing in 10 Italian centers, between 1961 and 1966. Of these patients 205 have died; 131 (77 males and 54 females) are still alive and no informations could be obtained for the remaining 51 (13%). The overall survival of patients treated during this period of time is therefore not less than 34% which is comparable to that of general population of the same age group. The 131 patients still alive have totaled 1,486 years of pacing and have used up to 784 pacers. Comparing the incidence of the most common causes for replacement during the periods 1961-66 and 1973-77, electrode failures dropped from 21 to 0.9%; circuitry malfunctions occurred in 10.5 and 7.8%; battery depletion rose from 36.8 to 69% of the cases. According to their clinical conditions, the 131 patients on long-term follow-up can be grouped as follows: 62% are in class 1 or 2 of NYHA; 26.7% are in class 3, and 3.8% in class 4. Moreover, 53.4% of patients are living an active life, having some sort of occupation and 29% are holding a driving license.
