Gradenigo’s syndrome with abscess of the petrous apex in pediatric patients: what is the best treatment?
No full textBackground: Gradenigo’s syndrome is defined by the classic clinical triad of ear discharge, trigeminal pain, and abducens nerve palsy. It has become a very rare nosological entity after the introduction of antibiotics, so that has been defined as the “forgotten syndrome.” However, the underlying pathological process (apical petrositis) still represents a life-threatening condition that shall be immediately recognized in order to address the patient to the proper therapy. The therapy itself may be an argument of discussion: on a historical background ruled by surgery, reports of successful conservative antibiotic treatment have risen in recent years. Methods and Results: We reported a case of Gradenigo’s syndrome in a child with an abscess of the left petrous apex and initial involvement of the carotid artery. After multidisciplinary evaluation, we decided to encourage conservative treatment, until complete regression was observed. Discussion: The available literature of the last 10 years was reviewed, with particular attention to the presence of an apical abscess and the therapeutic approach. The principles of management with regard to conservative therapy versus surgical indications are therefore examined and discussed
Awake versus sleep endoscopy: Personal experience in 250 OSAHS patients|Endoscopia in veglia versus in sonno: La nostra esperienza in 250 pazienti con OSAHS
No full textIdentifying the site of obstruction and the pattern of airway change during sleep are the key points essential to guide surgical treatment decision making for Obstructive Sleep Apnoea-Hypopnoea Syndrome in adults. In this investigation, 250 cases were retrospectively analyzed in order to compare the pharyngolaryngeal endoscopic findings detected in the awake state, with those obtained in drug-induced sedation, by means of the Sleep Endoscopy technique. All endoscopic findings have been classified according to the semi-quantitative NOH staging. The awake and sedation NOH resulted identical in 25% of the cases only, while the discrepancies involved the oropharyngeal and hypopharyngeal sites, respectively in about 33% and 50% of the patients. The laryngeal obstructive role detected during sedation in almost 33% of the cases was both unforeseen and relevant, with all the consequent implications in the treatment choices particularly for the surgical cases
WASTE PLASTICS MANAGEMENT IN MUNICIPALITIES: LOGISTICS AND PROCESSES IN LOMBARDIA (NORTHERN ITALY)
Full text linkA partnership of 49 Municipalities lying in Lombardia (Northern Italy) and belonging to the District “Monza
and Brianza” has entrusted the management of the Municipal Solid Waste (MSW) to two Public Companies:
“C.E.M. Ambiente S.p.A.” - which owns and operates a transfer station and a multi-material centre - and “SERUSO
S.p.A.”, whose single facility is set up and equipped for a high performance factory sorting of the dry fraction of the urban waste.
The catchment area is populated by 448 000, living in an area of 366 km2. The management system starts with household sorting for multi-bin curbside collection; followed by hauling to selection and physical treatment facilities; and last, transport of the selected fractions to final destinations.
The yearly throughput of “C.E.M. Ambiente” is about 296 000 t, of which over 70% home-sorted. Extra-CEM customers add to this amount about 40 000 t/yr. When calculated on the partner municipalities, the waste
generation rate is almost 1.8 kg/capita per day including waste from craftsmen and workshops. Less than 1% of the
collected waste goes to landfill and about 8% to incineration with energy recovery (WTE). Since “C.E.M. Ambiente”
operates mainly the logistics, however; and part of the materials recovery is actually made downstream its gate at
“SERUSO” facility, where some by-products are unavoidably generated; the overall share of WTE will be slightly higher.
Electric energy produced from the combustible by-products of “C.E.M. Ambiente” and “SERUSO” covers
largely the energy needs of the recovery and cleaning processes. It is worthwhile stressing that in this district also waste from street sweeping – as much as 8 200 t/yr – is turned into sand, gravel and like for civil works. “C.E.M. Ambiente” uses also fuel energy, to operate collection and hauling vehicles and factory handling machines, all of them powered by Diesel engines. Fuel requirements for TS and MMC in 2011 were 78 405 and 14 605 litres, respectively. Regrettably, these needs cannot be satisfied in any way with recovered energy
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
