Use of QT intervals for a more accurate diagnose of syncope and evaluation of syncope severity.

2014

Abstract BACKGROUND: This study aimed to evaluate the use of QT intervals, their diagnostic predictive value in patients with syncope and their relationship with syncope severity. METHODS: One hundred and forty nine patients with a diagnosis of syncope were admitted to Internal Medicine departments at the University of Palermo, Italy, between 2006 and 2012, and 140 control subjects hospitalised for other causes were enrolled. QT maximum, QT minimum, QTpeak, QT corrected, QT dispersion and Tpeak-to-Tend interval were compared between two groups. The paper medical records were used for scoring with San Francisco Syncope Rule (SFSR), Evaluation of Guidelines in SYncope Study (EGSYS) score and …

The management of abdominal hydatidosis after the rupture of a pancreatic hydatid cyst: a case report

2015

Introduction Echinococcosis or hydatidosis is a zoonosis caused by cestodes from the genus Echinococcus; its habitat is the small intestine of the definitive host, represented by dogs/carnivorous animals, where it produces eggs which are eliminated in the environment. Cystic echinococcosis represents more than 95% of the hydatidosis cases registered annually. The most frequent localization is the hepatic one, followed by the pulmonary localization with a ratio of 2.5:1. A pancreatic localization represents 0.2% of hydatidosis cases with a higher possibility of disseminating intra-abdominally. The incidence of hydatidosis in Romania has not been investigated yet through national studies. Cas…

Reproducibility of electrocardiographic findings in patients with suspected reflex neurally-mediated syncope

2008

The reproducibility of electrocardiographic (ECG) recordings in syncopal recurrences and the diagnostic role of nonsyncopal arrhythmias are not well known. The objective of this study was to analyse the reproducibility of the ECG findings recorded with implantable loop recorders in 41 patients with suspected neurally-mediated syncope who were included in the International Study on Syncope of Uncertain Origin-2 study and that had > or =2 events recorded by implantable loop recorders. In these patients, the electrocardiogram obtained with the first documented syncope (index syncope) was compared with other recorded events. Twenty-two patients had > or =2 syncopes, and their electrocardiograms…

Biodiversità nella dendroflora italiana

2013

Nella flora vascolare indigena d’Italia, costituita da circa 7000 taxa specifici e infraspecifici, quelli arborei sono rappresentati da un modesto numero di unità. Tra gimnosperme e angiosperme non si superano 200 specie. Diversificano e arricchiscono la dendroflora italiana specie legnose policormiche o arbustive che, con l’età e in particolari condizioni, possono assurgere a veri e propri alberi. Vi contribuiscono anche espressioni genetiche di classiche specie arboree variamente interpretate a livello tassonomico. La dendroflora qui esaminata si riferisce a 53 generi (7 gimonosperme e 46 angiosperme). I taxa specifici e infraspecifici sono 188 (21 gimnosperme e 167 angiosperme). Non poch…

Molecular phylogeny of Malagasy poison frogs, genus Mantella (Anura: Mantellidae): homoplastic evolution of colour pattern in aposematic amphibians

2002

Abstract We studied the evolution of colour pattern in Malagasy poison frogs, genus Mantella , a group of diurnal and toxic frogs endemic to Madagascar. Based on a phylogeny reconstructed using 1130 bp of the mitochondrial 16S rRNA gene, the genus can be divided into five species groups. Within some of these groups, interspecific genetic divergences were very low (1.2–2.8% sequence divergence) while colour patterns were markedly different. In contrast, Mantella madagascariensis and M . baroni , two species which show extremely similar dorsal coloration patterns, were not included in the same clade. This conclusion was supported by high bootstrap values and by significant rejection of altern…

Marine sponges are a very attractive and rich source in the production of novel bioactive compounds. The sponges exhibit a wide range of pharmacological activities. The genus Amphimedon consists of various species, such as viridis, compressa, complanata, and terpenensis, along with a handful of undescribed species. The Amphimedon genus is a rich source of secondary metabolites containing diverse chemical classes, including alkaloids, ceramides, cerebrososides, and terpenes, with various valuable biological activities. This review covers the literature from January 1983 until January 2018 and provides a complete survey of all the compounds isolated from the genus Amphimedon and the associate…

Dispacamide E and other bioactive bromopyrrole alkaloids from two Indonesian marine sponges of the genus Stylissa.

2014

Chemical investigation of methanolic extracts of the two Indonesian marine sponges Stylissa massa and Stylissa flabelliformis yielded 25 bromopyrrole alkaloids including 2 new metabolites. The structures of all isolated compounds were unambiguously elucidated based on extensive 1D and 2D NMR, LR-MS and HR-MS analyses. All isolated compounds were assayed for their antiproliferative and protein kinase inhibitory activities. Several of the tested compounds revealed selective activity(ies) which suggested preliminary SARs of the isolated bromopyrrole alkaloids.

Extremal properties of the determinant of the Laplacian in the Bergman metric on the moduli space of genus two Riemann surfaces

2005

We study extremal properties of the determinant of the Laplacian in the Bergman metric on the moduli space of compact genus two Riemann surfaces. By a combination of analytical and numerical methods we identify four non-degenerate critical points of this function and compute the signature of the Hessian at these points. The curve with the maximal number of automorphisms (the Burnside curve) turns out to be the point of the absolute maximum. Our results agree with the mass formula for orbifold Euler characteristics of the moduli space. A similar analysis is performed for the Bolza's strata of symmetric Riemann surfaces of genus two.

Progressive visceral leishmaniasis misdiagnosed as cirrhosis of the liver: a case report

2009

Abstract Introduction Visceral leishmaniasis is a potentially life-threatening infectious disease which is caused by parasites of the genus Leishmania and characterized in most cases by the presence of fever as well as signs and symptoms similar to those found in liver cirrhosis. Case presentation In this case report we describe the history of a 50-year-old Caucasian man incorrectly diagnosed as having hepatitis C virus-associated liver cirrhosis, with a massive weight loss of around 100 kg during the previous 2 years. However, suspecting a lymphoproliferative disorder, we were able to make a correct diagnosis of visceral leishmaniasis by bone marrow examination. After a course of therapy w…
