Chest pain is one of the most frequent reasons for presentation to the emergency department (ED), although the estimated prevalence of AMI (acute myocardial infarction) in the ED is about 4%. One criterion for diagnosis of AMI is the demonstration of a rise and/or fall in cardiac troponins, but time is needed for this to happen. Thus, the use of an additional 'early marker' of cardiac injury may aid to exclude AMI rapidly. The aim of the study was to evaluate the possibility of excluding AMI with the determination of heart-type fatty acid-binding protein (H-FABP) on baseline samples of patients referring to the ED for chest pain. 26 AMI patients and 41 non-AMI comparisons were included in the study. Both H-FABP and high sensitivity cardiac troponin T (hs-cTnT) were measured in baseline samples from these subjects. H-FABP had a negative predictive value of 100%, thus indicating the possibility of its usage in a rule-out strategy for AMI in ED for patients presenting with chest pain.

The Desio Diabetes Diagram i.v. 140-180 protocol, fully managed by nurses, with insulin and glucose intravenous infusion proved effective, safe and feasible in maintaining blood glucose between 140 and 180 mg/dL in patients with diabetes or hyperglycaemia admitted to the intensive cardiac care unit for acute cardiac events.

AimInsulin is the preferred treatment for the control of diabetes in hospital, but it raises the risk of hypoglycaemia, often because oral intake of carbohydrates in hospitalized persons is lower than planned. Our aim was to assess the effect on the incidence of hypoglycaemia of giving prandial insulin immediately after a meal depending on the amount of carbohydrate ingested.MethodsA prospective pre–post intervention study in hospitalized persons with diabetes eating meals with stable doses of carbohydrates present in a few fixed foods. Foods were easily identifiable on the tray and contained fixed doses of carbohydrates that were easily quantifiable by nurses as multiples of 10 g (a ‘brick’). Prandial insulin was given immediately after meals in proportion to the amount of carbohydrates eaten.ResultsIn 83 of the first 100 people treated with the ‘brick diet’, the oral carbohydrate intake was lower than planned on at least one occasion (median: 3 times; Q1–Q3: 2–6 times) over a median of 5 days. Compared with the last 100 people treated with standard procedures, postprandial insulin given on the basis of ingested carbohydrate significantly reduced the incidence of hypoglycaemic events per day, from 0.11 ± 0.03 to 0.04 ± 0.02 (P < 0.001) with an adjusted incidence rate ratio of 0.70 (95% confidence interval 0.54–0.92; P = 0.011).ConclusionsIn hospitalized persons with diabetes treated with subcutaneous insulin, the ‘brick diet’ offers a practical method to count the amount of carbohydrates ingested, which is often less than planned. Prandial insulin given immediately after a meal, in doses balanced with actual carbohydrate intake reduces the risk of hypoglycaemia.

Introduction Large pleural and pericardial effusion is a common finding in lung cancer patients. However, a chronic large pleural effusion and the “lung entrapment” fenomenon, due to the neoplastic lung infiltration, could precipitate the re–expansion pulmonary edema (REPO) after the thoracentesis procedure. REPO is a rare and potentially life–threatening complication after large volume thoracentesis. It is characterized by alveolar infiltration in the reexpanded lung.Indeed, in the presence of “lung entrapment”, REPO development could be due not only to and excessive fluid removal, but also to the development of an excessively negative intrapleural pressure (&lt; – 20 mmHg). As the REPO is often associated to an hemodynamic impairment, in patients with concomitant severe pericardial effusion, this condition could cause cardiac tamponade and the optimal therapeutic approach could be challenging.In this perspective, the decision on the effusion to be drained first, in this population, is not always straightforward.Case report In a 62 years –old woman with severe respiratory failure, a chest CT scan showed a massive left –sided pleural effusion with a complete collapse of the left lung, a severe pericardial effusion (35 mm) and the presence of malignant mediastinal nodes. (Figure 1).In the ICU a left thoracentesis was performed, with an early drainage of 1400 ml, the drain was then clamped. 30 minutes later, the patient developed a severe acute respiratory failure. An urgent chest x ray revealed an ipsilateral pulmonary oedema (Figure2). The patient was then treated with respiratory support with cPAP and intravenous diuretic therapy. Afterward, a rapid hemodynamic derangement occurred, with cardiac tamponade. An emergency echoguided pericardiocentesis was then performed followed by an immediate recovery. A repeated thorax CT scan revealed an advanced pulmonary tumor (Figure 3). Discussion In this case all the risk factors for REPO were coexistent: chronic pleural effusion and lung cancer. In addition, the large pericardial effusion represented a complicating factor in this situation as both the cPAP and the REPO’s hypovolemia may have brought to a clinical tamponade. In this context, where a neoplastic severe pleural and pericardial effusions are coexistent, it is essential to know which possible complications may occur after a large volume thoracentesis in order to prevent a high risk urgent pericardial drainage in patient with severe respiratory distress.
