Salmonella infections can be seen in four clinical types, namely gastroenteritis, bacteremia/sepsis, enteric fever and carriage. These infections can result in uncomplicated diarrhea in most cases, but can lead to invasive disease requiring antimicrobial therapy and can be life-threatening in elderly or immunocomprimised patients. Broad-spectrum cephalosporins and fluoroquinolones are crucial options in the treatment of the invasive infections. Ciprofloxacin resistance is rarely seen in non-typhoid Salmonella enterica isolates, and only in S...

Many clinically important differences exist between beta blockers. B1-selectivity is of clinical interest because at clinically used doses, b1- selective agents block cardiac b-receptors while having minor effects on bronchial and vascular b-receptors. Beta-adrenergic blocking agents significantly decrease the frequency and duration of angina pectoris, instead the prognostic benefit of beta-blockers in stable angina has been extrapolated from studies of post myocardial infarction but has not yet been documented without left ventricular disfunction or previous myocardial infarction...

Stress cardiomyopathy is an acute transient left ventricular dysfunction, associated with emotional stress. In the course of alcohol withdrawal abnormalities of perfusion and myocardial contractility have been described, manifested in the scintigraphic study, with the absence of changes in ECG and echocardiography and probably caused by sympathicotony, in analogy to severe emotional stress. We present a case of acute left ventricular dysfunction during alcohol withdrawal with significant changes in echocardiography and ECG mimicking acute coronary syndrome...

Up till now ST-segment elevation myocardial infarction (STEMI) is an important clinical and epidemiological question because of its high incidence and death rate. In this light, intervention principles continue to be developed to reach a precise diagnosis and a fast transport of the patient towards adequate hospitals. As the only instrument able to modify the natural course of this disease is the early restoration of coronary flow in the myocardial ischemic area, we can understand that time to reperfusion is the driving parameter in defining sanitary and therapeutic ways aimed at facing up to this pathology in its acute phase and limiting the subsequent chronic disfunction...

Genetic factors that increase susceptibility to oxidative stress, endothelial disfunction and, possibly, stroke include angiotensin-converting enzyme gene deletion polymorphism (ACE-DD) and the methylentetrahydropholate reductase (MTHFR) C677-TT polymorphism. The relationship of ACE-DD genotype to ischemic stroke and cardiovascular disease is controversial, but it has been independently linked to lacunar infarction, in the absence of carotid atheroma. Lea et al. (2005) reported that the ACE DD genotype acts in combination with the MTHFR T/T genotype to increase migraine susceptibility, with the greatest effect in those with aura...

Aim of the study was to assess influence of long-term therapy with angiotensin converting enzyme inhibitor lisinopril on morphofunctional parameters of the left ventricle (LV) and painless myocardial ischemia in 109 premenopausal women with stage II hypertension depending on functional state of peripheral artery endothelium. The results show that lisinopril therapy in premenopausal women with hypertension can stop or even cause regression of LV myocardial hypertrophy and produce favorable effect on LV remodeling mostly in women with concentric type of hypertrophy and/or without endothelial dysfunction, and has positive effect on frequency of painless myocardial ischemia events...

Existing molecular knowledge base of cardiovascular diseases is rudimentary because of lack of specific attribution to cell type and function. The aim of this study was to investigate cell-specific molecular remodeling in human atrial and ventricular myocytes associated with ischemic cardiomyopathy. Our strategy combines two technological innovations, laser-capture microdissection of identified cardiac cells in selected anatomical regions of the heart and splice microarray of a narrow catalog of the functionally most important genes regulating ion homeostasis...

Myocardial ischemia occurs for a mismatch between blood flow and metabolic requirements, when the rate of oxygen and metabolic substrates delivery to the myocardium is insufficient to meet the myocardial energy requirements for a given myocardial workload. During ischemia, substantial changes occur in cardiac energy metabolism, as a consequence of the reduced oxygen availability. Some of these metabolic changes are beneficial and may help the heart adapt to the ischemic condition. However, most of the changes are maladaptive and contribute to the severity of the ischemic injury leading stunned or hibernating myocardium, cell death and ultimately to contractile disfunction...

BACKGROUND: An increasing number of patients undergoing percutaneous interventions (PI) have experienced previous coronary artery bypass graft surgery (CABG). However, the impact of PI on outcomes in such patients is currently unclear. We evaluated the immediate and 1-year clinical outcomes of post-CABG patients who underwent PI in a tertiary center. METHODS: From January-2005 to September-2006, 91 consecutive post-CABG patients underwent 197 stent implantations (84% drug-eluting stents) for 154 lesions...

152 patients with ischemic heart disease aged from 46 to 60 years have been observed. Among these patients, 69 were with stable stenocardia, 32--with unstable stenocardia and 53--in stage related to acute heart attack. Normal geometry of the heart was found in 33% of patients with stable stenocardia, excentric hypertrophy was found in 30% of patients with stable stenocardia. Excentric hypertrophy prevailed in patients with unstable stenocardia and myocardial infarction. Systolic disfunction of the myocardium was found in 72% of patients with stable stenocardia, in 41% of patients with unstable stenocardia and in 43% of patients with myocardial infarction...
