Published: August 2013

AbstractBackgroundDetermining the level of nodal metastases may help decrease the extent of neck dissections and reduce morbidity.MethodsA prospective study of neck dissections in patients with oral cancer was conducted. Each nodal level was delineated, sent for histopathology, and reported level‐wise. Incidence of overall and isolated metastatic nodes at different levels was calculated. Logistic regression was used to find factors predicting metastases to levels IIB and V.ResultsFive hundred eighty‐three neck dissections were prospectively evaluated. A total of 95.7% metastases occurred at levels I to IV. Overall incidence of metastases to levels IIB and V was 3.8% and 3.3%, respectively. Multivariate analysis revealed IIA positivity as an independent predictive factor for metastases to both IIB and V.ConclusionThis study of lymph node mapping in patients with oral cancer showed a predictable pattern of lymph node metastasis according to primary site. Selective neck dissection (levels I–IV) in patients with oral cancers may be adequate. Determining status of level IIA is important to guide dissection of levels IIB and V. © 2014 Wiley Periodicals, Inc. Head Neck, 36: 1503–1507, 2014
Development of monetite/phosphorylated chitosan composite bone cement

Published: August 2013

AbstractIn this article, we report the development of a biodegradable monetite [dicalcium phosphate anhydrous (DCPA), CaHPO4]/phosphorylated chitosan (p‐chitosan) composite orthopedic cement. The cement pastes showed desirable handling properties, injectability, and washout resistance. The incorporation of p‐chitosan powders at 5 wt % shortened the setting time of DCPA and significantly improved the mechanical performance of DCPA cement, increasing the compressive strength almost twice from 11.09 ± 1.85 MPa at 0% chitosan to 23.43 ± 1.47 MPa at 5 wt % p‐chitosan. On the other hand, higher p‐chitosan content or untreated chitosan incorporation lowered the performance of DCPA cements. The cytocompatibility of the composite cement was investigated in vitro using the preosteoblast cell line MC3T3‐E1. An increase in cell proliferation was observed in both DCPA and DCPA–p‐chitosan. The results show that both the materials are as cytocompatible as hydroxyapatite. Based on these results, DCPA–p‐chitosan composite cement can be considered as potential bone repair material. © 2013 Wiley Periodicals, Inc.

ABSTRACTObjectiveTo review systematically the medical literature reporting on the prevalence of a niche at the site of a Cesarean section (CS) scar using various diagnostic methods, on potential risk factors for the development of a niche and on niche‐related gynecological symptoms in non‐pregnant women.MethodsThe PubMed and EMBASE databases were searched. All types of clinical study reporting on the prevalence, risk factors and/or symptoms of a niche in non‐pregnant women with a history of CS were included, apart from case reports and case series.ResultsTwenty‐one papers were selected for inclusion in the review. A wide range in the prevalence of a niche was found. Using contrast‐enhanced sonohysterography in a random population of women with a history of CS, the prevalence was found to vary between 56% and 84%. Nine studies reported on risk factors and each study evaluated different factors, which made it difficult to compare studies. Risk factors could be classified into four categories: those related to closure technique, to development of the lower uterine segment or location of the incision or to wound healing, and miscellaneous factors. Probable risk factors are single‐layer myometrium closure, multiple CSs and uterine retroflexion. Six out of eight studies that evaluated niche‐related symptoms described an association between the presence of a niche and postmenstrual spotting.ConclusionsThe reported prevalence of a niche in non‐pregnant women varies depending on the method of detection, the criteria used to define a niche and the study population. Potential risk factors can be categorized into four main categories, which may be useful for future research and meta‐analyses. The predominant symptom associated with a niche is postmenstrual spotting. Copyright © 2013 ISUOG. Published by John Wiley & Sons Ltd.

AbstractThe availability of resources, their effect on population density and territoriality, and the ways in which these factors are interwoven with mating systems are important determinants of small mammal space use. It is often difficult to study these patterns in an integrated way, however, especially because long‐term data are needed but not readily available. In this paper, we investigate effects of population density, season and breeding status on home range patterns of the promiscuous rodent Mastomys natalensis using monthly capture‐mark‐recapture data collected over 17 years in a 3‐ha grid. Home ranges were estimated using minimum convex polygons bounded by trap locations, and home range overlap and visitation rates were calculated as a measure of territoriality. As higher population densities coincide with increased resource availability, we predicted that home range sizes would correlate negatively with density. Furthermore, as M. natalensis is promiscuous and population densities are generally high, we predicted that territoriality would be low, and home range overlap would therefore be high. Contrary to expectations the home ranges of female adults increased with population density, although those of male adults and subadults followed the expected decrease. Home range overlap and visitation rates were generally high, and increased significantly with population density. More importantly, they were never lower than those of simulated datasets consisting of randomly moved home ranges. These results therefore suggest that M. natalensis displays a complete lack of territoriality that is rarely seen in small mammals but still meets predictions based on knowledge of density and mating system.
Specific Psychosocial Issues of Individuals Undergoing Genetic Counseling for Cancer – A Literature Review
Authors: Eijzenga Willem , Hahn Daniela EE , Aaronson Neil K , Kluijt Irma , Bleiker Eveline MA 
Published: August 2013

AbstractApproximately 25 % of individuals undergoing genetic counseling for cancer experiences clinically relevant levels of distress, anxiety and/or depression. However, these general psychological outcomes that are used in many studies do not provide detailed information on the specific psychosocial problems experienced by counselees. The aim of this review was to investigate the specific psychosocial issues encountered by individuals undergoing genetic counseling for cancer, and to identify overarching themes across these issues. A literature search was performed, using four electronic databases (PubMed, PsychInfo, CINAHL and Embase). Papers published between January 2000 and January 2013 were selected using combinations, and related indexing terms of the keywords: ‘genetic counseling’, ‘psychology’ and ‘cancer’. In total, 25 articles met our inclusion criteria. We identified the specific issues addressed by these papers, and used meta‐ethnography to identify the following six overarching themes: coping with cancer risk, practical issues, family issues, children‐related issues, living with cancer, and emotions. A large overlap in the specific issues and themes was found between these studies, suggesting that research on specific psychosocial problems within genetic counseling has reached a point of saturation. As a next step, efforts should be made to detect and monitor these problems of counselees at an early stage within the genetic counseling process.

Published: August 2013

AbstractWe develop a theory of group actions and coverings on Brauer graphs that parallels the theory of group actions and coverings of algebras. In particular, we show that any Brauer graph can be covered by a tower of coverings of Brauer graphs such that the topmost covering has multiplicity function identically one, no loops, and no multiple edges. Furthermore, we classify the coverings of Brauer graph algebras that are again Brauer graph algebras.
Veii: the Valghetta Baths (‘Bagni Della Regina’)
Authors: Jones G. D. B. 
Published: August 2013

The plateau on which the site of Veii stands is bounded by the steeply eroded valleys of the Fosso Piordo and the Torrente Valchetta, the ancient river Cremera. A kilometre to the north-east of their confluence near the Piazza d'Armi, the site of the bath-house serving the Roman municipium Augustum Veiens was exposed by river erosion in November 1959 (fig. 1). It lies across the narrow floor of the Valchetta ravine, where the river has changed course frequently since classical times. The ancient approach probably lay along a small track leading from the edge of the main town plateau immediately above the baths. This choice of position, which certainly had pre-Roman associations, was determined by the presence of a number of hot springs which break through the valley floor at this point. They are the result of quiescent volcanic activity; another example occurred on the opposite side of Veii, in the Vignacce area of the Fosso Piordo.The site was known to antiquarians of the last century. Canina mentions the baths briefly (p. 73) and reproduces an engraving of them (Tav. XX) in Antica cittá di Veio (1847), which presumably shows the outer shell of the building before the river broke into it (pl. XX, a). It illustrates a vital point in understanding the remains as they stand at present.
Il mosaico absidale di san teodoro a Roma: problemi storici e restauri attraverso disegni e documenti inediti
Authors: Bolgia Claudia 
Published: August 2013

THE APSE MOSAIC OF SAN TEODORO IN ROME: AN ASSESSMENT OF ITS HISTORY AND RESTORATION BASED ON UNPUBLISHED DRAWINGS AND DOCUMENTSThe apse mosaic of San Teodoro presents numerous complicated problems. It has been heavily altered over the centuries, and the extent of these alterations has seriously impeded scholarly study. Comparison of the known extant antiquarian drawings, together with important unpublished archival documents, permits the reconstruction of its conservation history. This is considerably more complex than had been thought previously. The identification of at least four extensive, and often clumsy, restoration campaigns produces a new and precise definition of the parts of the original mosaic that survive. These manifest a level of quality scarcely imaginable earlier, and allow new technical and stylistic comparisons to be made in order to verify the commonly accepted chronology. The new documentation yields important information about the apse mosaic itself, and throws light on the history of Roman restoration workshops, mosaic-workers, materials and setting techniques.

The Odyssey frescos of the Via Graziosa: a proposed context
Authors: Coarelli Filippo 
Published: August 2013

LE PITTURE CON SCENE DELL'ODISSEA DA VIA GRAZIOSA: UN TENTATIVO DI RICONTESTUALIZZAZIONELe pitture con scene dell'Odissea, scoperte tra il 1849 e il 1850 e conservate nei Musei Vaticani, costituiscono una delle opere capitali della pittura romana di secondo stile. La tendenza recente ad abbassarne la data fino all'età augustea e l'assenza di uno studio topografico adeguato inducono ad un tentativo di ricontestualizzazione, tanto sul piano cronologico quanta sul piano spaziale. Dal primo punto di vista, il ritrovamento awenuto contemporaneamente di frammenti di un calendario dipinto coevo alle pitture, che è dimostrabilmente pregiuliano, indica un terminus post quern non al 46 a.C: le pitture vanno quindi datate intorno al 50 a.C. circa. Dal secondo punto di vista la posizione della domus sul Cispius permette di identificarne l'atrio in un frammento della Pianta Marmorea Severiana. La presenza nella stessa zona del tempio di Mefitis e la scoperta nelle vicinanze di due iscrizioni che nominano i Papirii, suggeriscono di attribuire la casa a questa gens. Infatti, il tempio di Mefitis, probabilmente di carattere privato, è stato forse fondato, a seguito di evocatio, da L. Papirius Cursor, dopo il trionfo su Sanniti, Tarantini e Lucani del 272 a.C.
Pictorial cycles of non-biblical saints: the seventh- and eighth-century mural cycles in Rome and contexts for their use

CICLI PITTORICI DEI SANTI NON BIBLICI: I CICLI MURALI A ROMA NEL SETTIMO E NELL'OTTAVO SECOLO E IL CONTESTO DEL LORO USOUn gruppo di dipinti del settimo e dell'ottavo secolo, raffiguranti storie di santi non biblici, sopravvive a Roma. Sebbene relativamente pochi, questi dipinti rappresentano un distinto gruppo di narrative agiografiche, caratterizzati dal fatto che tutti i cicli sono costituiti da dipinti murali, che essi raffigurano per lo più santi orientali e che appaiono per la maggior parte in cappelle laterali o in spazi simili a cappelle delle diaconiae. Questo articolo analizza tali pitture nel contesto delle loro chiese di appartenenza ed intende dimostrare che i cicli sono fortemente influenzati da immigranti di lingua greca a Roma, dal culto dei santi e delle reliquie da essi promulgate) e dall'interesse per i santi non biblici tipico dei membri del ceto laico.
Excavations at Sphagion in Cyprus
Authors: Hennessy J. B. 
Published: August 2013

The Cemetery at Sphagion was excavated during the last week of August 1951, under the auspices of the Ashmolean Museum—Sydney University expedition to Cyprus with the aid of funds contributed jointly by the University of Sydney and the Australian Institute of Archaeology, Melbourne, which now possesses the finds allotted to the expedition by the Department of Antiquities. Tomb 17 is in the Cyprus Museum. The University of Sydney has made a generous grant towards the cost of illustration.The site at Sphagion (so called because of a nearby slaughter-house) lies on the outskirts of the village of Myrtou (Kyrenia District) in North-west Cyprus (fig. 1). It is situated immediately to the North of the main Myrtou-Nicosia road, within a few metres of the 20-mile post from Nicosia. The narrow, flat tract of land, now used for the cultivation of vines and olives, has a shallow surface soil overlying the soft white limestone into which the graves were cut. The land belongs to Eleni Hadji Sophokli of the village of Myrtou.
Notes on Southern Etruria and the Ager Veientanus
Authors: Perkins J. B. Ward 
Published: August 2013

The notes that follow are the first results of a programme of field-survey undertaken by the writer and by various members of the British School during the autumn of 1954 in the area that lies immediately to the north of Rome, between the Tiber and the sea. This area is one that has been strangely neglected by modern students of Italian topography. Ashby's published work is concerned mainly with those parts of the Campagna that lie to the south and east of Rome; and Tomassetti's work, invaluable as a repertory of manuscript and published sources, lays no claim to be a comprehensive survey of the material remains surviving on the ground.Such a survey is badly needed today. The romantic desolation of Southern Etruria is being transformed from one day to the next under the impact of a scheme of landreform comparable in scale to the great reforms of classical antiquity, and vast estates which for centuries have been used for stock-breeding and seasonal pasture are being broken up and brought into cultivation with all the devastating thoroughness that modern mechanical equipment entails. Whole regions are accessible today as they have never been before, and within them the bulldozer and the mechanical plough are busy destroying whatever lies in their path.
Nuovi testi di leggende agiografiche beneventane
Authors: De Stefano Antonino 
Published: August 2013

Tra i manoscritti conservati nella Biblioteca Arcivescovile di Benevento esiste un lezionario contenente parecchie leggende agiografiche beneventane che è rimasto sino ad oggi sconosciuto.Benchè relativamente recente, questo manoscritto è però molto importante per più d'un titolo. Anzitutto perchè esso è indubbiamente copia immediata di antichissimi codici, poi perchè ci fornisce il principio e la fine della leggenda della Translatio dei dodici Fratelli Martiri, pubblicata già dal Giovardi acefala ed apoda: infine perche ci offre una leggenda riferentesi a San Giovenale martire, di cui, come vedremo, nulla pare sia mai stato pubblicato.Il codice di scrittura secentesca o settecentesca, è cartaceo, legato in pergamena, costa di 40 fogli, di cui però otto sono completamente bianchi, e misura cm. 26 1/2 × 20 1/2. Sulla copertina una mano posteriore ha riprodotto il titolo della prima leggenda. Il codice è stato scritto da due mani, indipendenti, e press'a poco contemporanee.
Excavations beside the North-West Gate at Veii, 1957–58
Authors: Ward-Perkins J. B. 
Published: August 2013

The excavations here described were undertaken by the British School at Rome on behalf of the Superintendency of Antiquities for Southern Etruria, through the courtesy of its Superintendent, Professor Renato Bartoccini, who has done so much to foster active archaeological research within an area that is undergoing drastic and archaeologically disastrous change, and with the active and cordial collaboration of his staff. The purpose of the excavations was the strictly limited one of examining, while there was yet time, one of the few remaining stretches of the defences of Veii where ploughing in recent years had revealed (and is now rapidly destroying) substantial remains of the ancient walls. In the course of the work such other features as came to light were examined and recorded so far as this limited purpose permitted; but no attempt was, or could be, made to follow up the larger implications of these discoveries, which must await another occasion and other hands.The work was undertaken in two short campaigns, each of between two and four weeks' duration. The first of these, in November and December 1957, was hampered by the ravages of Asian influenza, the work of supervision being shared in succession by Mrs. Selina Tomlin (now Mrs. Ballance), Mr. Guy Duncan and Mr. Michael Ballance; and it is greatly to their credit that, despite these difficulties, a satisfactory and coherent result was obtained. The second campaign took place in October-November 1958, and was supervised throughout by Mrs. P. W. Murray Threipland. Both in the field and the work-room a great deal of volunteer help was received both from students of the School and from friends and visitors, outstanding among the latter being Mrs. Anne Kahane and Mrs. Betty Eastwood and, during the second campaign, Mr. Eric Gray.
Underwater Exploration of the Ancient Port of Nora, Sardinia
Authors: Wilkes W. G. St. J. , Macnamara Ellen 
Published: August 2013

On the peninsula of Capo di Pula, which lies some 32 km. west of Cagliari on the south coast of Sardinia, are the ruins of a Roman town overlying those of Punic date. The peninsula is shaped like a triangle; one corner now touches the mainland and forms a narrow isthmus of sand; the outer two corners are rocky promontories surrounded by scarps. Here stood the ancient town; excavation has revealed considerable urban remains, including the foundations of a temple of Tanit, with fine Punic masonry dating back to the fifth century B.C., a street plan with many houses, mainly Roman but some of Punic masonry and possibly dating to the sixth century B.C. In this area was the Roman theatre. At the base of the isthmus there are some Punic tombs along the shore and the Tophet; the earliest stelae may be of sixth century date but most appear to be late Punic in style. Nearby may be seen traces of a Roman aqueduct and the little Romanesque church of S. Efisio is still standing.The site is generally accepted as that of the ancient Nora, one of the four principal Punic towns of Sardinia. Not only is this town known to have been near Cagliari, but a local inscription records a gift to the people of Nora made by Favonia Vera, and the dedication of the church recalls the tradition that S. Efisio was martyred at Nora.
The Cultivation of Millet in Roman Italy

Published: August 2013

LA COLTIVAZIONE DEL MIGLIO NELL'ITALIA ROMANAQuesto articolo dimostra che la policoltura dei cereali rimase normale in Italia in tutto il periodo romano. Entro questo quadro generale, il miglio era un prodotto importante e ubiquitario: si poteva adattare a una grande varietà di terreno e di clima ed aveva molteplici usi come cibo per gli uomini, foraggio per gli animali, becchime, e nella medicina. Era coltivato dai piccoli agricoltori come precauzione contro la sempre presente minaccia di un cattivo raccolto di altri cereali, in particolari quelli seminati in autunno, e dai proprietari di grandi terreni coltivabili per le necessità della tenuta e per la vendita al mercato.L'argomento è affrontato unendo testimonianze letterarie, archeologiche e comparate (dal periodo pre-classico e medievale) con particolare attenzione alla realtà agricola.
Luni and theAger Lunensis: The Rise and Fall of a Roman Town and its Territory

Published: August 2013

LUNI E L'AGER LUNENSISQuattro campagne di ricerca sono state eseguite tra il 1978 e il 1981 nella zona immediatamente circostante la città Romana abbandonata di Luna (Luni) in Liguria. Lo scopo della ricerca era di contribuire a spiegare come una grande città sia fiorita qui in epoca Romana, e perchè sia sparita agli inizi del Medioevo. La ricerca archeologica di superficie (parte 2) ha rivelato poco dell'epoca preistorica e medievale, ma ha individuato resti sparsi di fattorie Romane, specialmente nelle collinette che sovrastano la città. Queste fattorie collinari, una delle quali è stata scavata (Parte 3), sembra siano state abbandonate verso la fine del I sec. d.C, e viene ipotizzato che esse dipendessero per la loro sussistenza dalla produzione e dall'esportazione di vino e olio. La Parte 4 esamina in dettaglio i problemi connessi con la scoperta di insediamenti altomedievali in questa zona. La Parte 5 è il resoconto di una ricognizione geomorfologica nella zona del porto di Luna, che ha messo in luce l'esistenza a ovest della città di un bacino portuale poco profondo, e ha documentato il suo processo graduale di riempimento in epoca post-classica. Nella Parte 6 sono illustrate alcune conclusioni generali e i rapporti tra la città e il suo entroterra.
