Diagnosis and therapeutic management of primary headache in an emergency setting

2013

Introduction and aim: Much headachers are under or mis-diagnoses and data regarding the proportion of patients attending an emergency department (ED) because of headache are still few. We conducted a retrospective observational study in an ED with the following aims: (a) estimate the proportion of headache attending to an ED (b) to estimate and describe the therapeutic management of primary headache and (c) to assessment the exam most frequently requested. Materials and methods: We collected data regarding patients diagnosed with headache consecutively attending the ED of the University of Palermo between September 2011 and March 2012. The study was approved by the ethics committee. Results: Between the semester evaluated 25110 subjects were admitted to ED headache suffers were equal to 1.6 %. Of these 263 (63.1 %) were woman and 154 (36.9 %). Mean age was 44.2 (DS ± 18.4) years (p = 0.068).According to ED registry headache admission was as follow assigned: 76.5 % with a diagnosis of headache 22.8 % with a secondary headache 0.7 % with Trigeminal Autonomic Cephalgias (TACs). Among those with a primary headache about 36 % of patient did not received a pharmacological treatment. Monotherapy was prescribed less frequently than combination therapy (19.1 vs 44.5 %).In monotherapy the most frequent medication were NSAIDs (28.3 %) benzodiazepines (26.7 %) and dopamine antagonists (11.7 %). Among those with a primary headache a CT scan was performed in the 124 subjects and 111 (34.8 %) had a neurologist consultation. Discussion: Our data are in line with the one previously reported in literature. The most frequently medication in the Italian ED were NSAIDs benzodiazepines dopamine antagonists and steroids. Neverless our data unlikely can be compared to other study give a snapshot. We believe that much more can be done to improve treatment of primary headache in ED.Settore MED/26 - Neurologia

Characterizations of {K,s+1}-Potent Matrices and Applications

2012

Recently, situations where a matrix coincides with some of its powers have been studied. This kind of matrices is related to the generalized inverse matrices. On the other hand, it is possible to introduce another class of matrices that involve an involutory matrix, generalizing the well-known idempotent matrix, widely useful in many applications. In this paper, we introduce a new kind of matrices called {K,s+1}-potent, as an extension of the aforementioned ones. First, different properties of {K,s+1}-potent matrices have been developed. Later, the main result developed in this paper is the characterization of this kind of matrices from a spectral point of view, in terms of powers of the ma…

Evaluation of changes in ion release and biological properties of NeoMTA‐Plus and Endocem‐MTA exposed to an acidic environment

2018

AIM To analyse in vitro changes in ion release and biological properties of Endocem-MTA (Maruchi, Wonju, Korea) and NeoMTA-Plus (Avalon Biomed Inc, Bradenton, FL, USA) exposed to acidic or neutral environment on human dental periodontal ligament stem cells (hPDLSCs). METHODOLOGY Cell viability and wound healing assays were performed using eluates of each material. Cell death and changes in phenotype induced by the set endodontic sealer eluates were evaluated through flow cytometry. To evaluate cell attachment to the different materials, hPDLSCs were directly seeded onto the material surfaces and analysed by scanning electron microscopy. The chemical composition of the materials was determin…

Response spectrum analysis of frame structures: reliability-based comparison between complete quadratic combination and damping-adjusted combination

2019

In the framework of seismic design of structures, response spectrum analysis (RSA) is the most commonly used approach in practice. The most popular combination rule is the complete quadratic combination (CQC) which is also prescribed by the most of seismic design codes and is based on the assumptions that the seismic acceleration is a white noise process and the peak factor ratios associated to the total and modal responses are unitary. Recently, the damping adjusted combination (DAC) rule has been developed for base-isolated structures to overcome the aforementioned simplified assumptions. Although it has been proved that the simplifications about peak factors lead to noticeable errors in …

Medium-term Culture of Normal Human Oral Mucosa: A Novel Three-dimensional Model to Study the Effectiveness of Drugs Administration

2012

Tissue-engineered oral mucosal equivalents have been developed for in vitro studies for a few years now. However, the usefulness of currently available models is still limited by many factors, mainly the lack of a physiological extracellular matrix (ECM) and the use of cell populations that do not reflect the properly differentiated cytotypes of the mucosa of the oral cavity. For this reason, we have developed a novel three-dimensional culture model reflecting the normal architecture of the human oral mucosa, with the main aim of creating a better in vitro model where to test cellular responses to drugs administration. This novel 3D cell culture model (3D outgrowth) was set up using an arti…

Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.

2016

Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…

The database included a total of 1549 lesions in 1304 patients with a mean age of 62 +/- 11years.

Patients presenting with ostial lesions did not differ from the remaining cohort except for a higher incidence of prior revascularisation.

Follow-up data were available at 385 [362-465] days.

The device-oriented composite endpoint occurred respectively in 12.6% and 4.6% at 12 months (log-rank p= 0.001).

Ionic liquids and microwave irradiation as synergistic combination for polar Diels–Alder reactions using properly substituted heterocycles as dienoph…

2012

For the DA reactions between nitropyrrole derivatives and isoprene, the combination of microwave irradiation and protic ionic liquid, has a notable synergistic effect. DFT calculations suggest that a supplementary energy ranking in the IR region of 1700-1400 cm-1 can favour the structural changes in the reactants to reach the TS. Fil: Mancini, Pedro Maximo Emilio.

2018

INTRODUCTION: The optimal bowel preparation strategy to minimise the risk of anastomotic leak is yet to be determined. This study aimed to determine whether oral antibiotics combined with mechanical bowel preparation (MBP+Abx) was associated with a reduced risk of anastomotic leak when compared to mechanical bowel preparation alone (MBP) or no bowel preparation (NBP).METHODS: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 Left Sided Colorectal Resection audit was performed. Patients undergoing elective left sided colonic or rectal resection with primary anastomosis between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary out…
