Note su Agapio, autore dell’ Eptalogo
Starting from the literary reconstruction that Photius offers, the present paper focuses on the character of Agapius and his doctrine.In the Bibliotheca (chap. 179) the patriarch mentions Agapius, defining him an impious man and attributing to him a work, composed of twenty-three treatises and some other chapters. Photius informs that in this writing the author pretends to profess the Christian faith, but, in reality, he reveals himself to be an enemy of Christ; however, he does not specify the title of the work of which the summary is reported.The patriarch also remembers Agapius in his Contra Manichaeos (50), equating him to a disciple of Mani, as well as identifying him as the author of the Heptalogue.The paper relates the information provided by Photius, which appears to be discordant in reference to the era in which the character would have lived, with those coming from other ancient sources. In doing so, the present paper pursues the attempt to identify the elements that allow Agapius to be placed in the history of the Christiandoctrine

Spondylolysis and spondylolisthesis in the pediatric and adolescent population
This article is a review of spondylolysis and spondylolisthesis in younger age groups. Since Herbinaux first described the pathology (1782), many classifications and theories of etiopathogenesis have been proposed. The congenital and isthmic types, as classified by Wiltse, are the most frequent in younger age groups, but the postsurgical progressive forms (3-5%) have been described as increasing in frequency secondary to neoplastic surgery in children. The general incidence is 4-5% at the age of 6 years, and in 30-50% of cases these types do not progress to spondylolisthesis. Most cases are asymptomatic (80%). Standard radiographic examinations (A-P, L, Oblique) are helpful in diagnosis and can suggest what the prognosis will be in terms of the evolution, and also what treatment is indicated (degree of slippage, slip angle, lumbar and lumbosacral index, SPTI). A bone scan (PBS and SPECT) is useful in the early stages of spondylolysis (pre-spondylosis). Although the CT scan is the most accurate examination, MRI is becoming important for diagnosis because of the frequency with which it is used as a primary investigation method. Depending on patient age, progression, degree of slippage, and symptoms, different therapeutic approaches have been proposed and are described in this paper

Esegesi, Vissuto Cristiano, Culto dei Santi e Santuari. Studi di Storia del cristianesimo per Giorgio Otranto
In occasione degli ottant’anni di Giorgio Otranto, colleghi, amici e allievi hanno provato a concretizzare la straordinaria mole di attività e di relazioni di cui si è intessuta la sua vita scientifica e accademica in una poderosa pubblicazione in suo onore. Gli argomenti dei contributi sono quelli che hanno caratterizzato la ricerca di Giorgio Otranto: l’esegesi cristiana antica, da cui, negli anni Settanta, ha preso avvio la sua carriera di studioso, la storia del vissuto cristiano, indagata in un’ottica multidisciplinare (iconografica, epigrafica, archeologica, oltre che storico-agiografica), il culto dei santi e dei santuari e la diffusione del culto micaelico.This volume collects a series of contributions by Italian and foreign authors related to exegesis, Christian living, saint worship, and shrines in the period between Late Antiquity and the Middle Ages
La familiarità nella scoliosi idiopatica.
Gli autori hanno esaminato un campione familiare di 70 pazienti,
affetti da scoliosi idiopatica, di sesso femminile, fino al terzo grado
di parentela, per un totale di 2055 soggetti. La genealogia dei
pazienti è stata ricostruita e correlata all’incidenza della patologia.
Nel lavoro vengono riportati i risultati dell’analisi statistica che
individuano una eterogeneità eziologica in cui vi sono quadri ad
ereditarietà multifattoriale e quadri a chiara trasmissione autosomica
dominante o autosomica recessiva. Per i quadri multifattoriali si
possono individuare alcuni fattori di rischio quali il sesso femminile
e l’essere primogenito.The aetiology of idiopathic scoliosis in unknown, and the genetic
hypothesis was proposed by many authors in the past. The scope of
this study was to verify this hypothesis. A group of seventy patients
affected by idiopathic scoliosis was selected and studied up to the
third generation for a total of 2055 persons. The genealogy was
investigated and correlated for scoliosis. The statistical analysis
revealed three different types of transmission: multifactorial; autosomic
dominant; autosomic recessive. Moreover female sex and
firstborn resulted as risk factors of idiopathic scoliosis in the group
of patients with multifactorial type of transmission
La concezione dei giudei come eretici tra tarda antichità e alto medioevo
Between Late Antiquity and Early Middle Ages, many times Jews are equated with heretics in Patristic literature, imperial law, council canons. Comparison with later hagiographical texts likening Jews to the heretics concurs in casting light on some sides of relationships between Jews, Christian and heretics and reconstructing a sort of Christian “ideology” about Judaism and other religious groups. Sources considered by the Author reflect a negative categorization of Judaism according to models and formulas which were crystallizing on the basis of ideological, political and religious propaganda. Such stereotypes shed light on the attitude and the positions of predominant groups towards presences, such as that of Jews, heretics and Muslims, felt like “different” or “other” ones, disrupting the Christian Orthodox community
Biomechanics of the conservative treatment in idiopathic scoliotic curves in surgical "grey-area"
The biomechanical behaviour of the spine significantly varies in relation to the age of the spine. Particularly, the elastic behaviour of the intervertebral discs has been proved to change during the spine growth, which changes the disc reaction to externally imparted forces. The biomechanical analysis of the G modulus of torsion rigidity of the intervertebral disc shows that the G values progressively increase through growth, which favours the progression of early scoliotic curves. At the same time, however, early structural scoliosis is more amenable to conservative treatment owing to the residual growth potential of the spine. Whereas indications to surgical treatment of scoliotic curves has been based upon the magnitude of the curves as measured according to the Cobb method, two additional factors affect the chance of correcting a scoliotic curve, The first is the residual growth potential of the vertebrae. In fact, a longer residual growth allows for external forces to be applied so as to change the growth model of the scoliotic spine, which ensures a stable correction of the deformity when these external forces are removed. The second is the magnitude of the elastic deformation of the intervertebral discs. It has been suggested that a deformation beyond the disc elastic behaviour, by producing hysteresis of the disc, renders the disc less susceptible to transferring the load to the neighbouring vertebral bodies, thus impairing remodelling. It ensues that both the age and the magnitude of rotation affects the success of conservative treatment and not only the magnitude in Cobb degrees. The curve localization adds to these two parameters, thoracic curves being stiffer than thoracolumbar and lumbar curves
Lumbar nerve root "walled" by a calcified herniated mass in a young patient
INTRODUCTION: Discal calcification in childhood is rare. Calcifications are occasionally discovered during routine examinations, especially in the cervical spine. Generally, the calcification process is confined to the nucleus pulposus of the intervertebral disc.
CASE REPORT: In this report, we describe the case of a 16-year-old girl who presented with acute low back pain, right S1 radiculopathy and a history of increasing paresthesia. The patient underwent a CT scan, which demonstrated a postero-lateral calcified disc hernia at the L5-S1 level. The surgical decompression of the lumbar nerve root was carried out; at the operation it was observed that the nerve root was "walled" into the calcified hernia.
DISCUSSION: Only a few cases with evidence of calcification of the herniated portion of the disc have been previously described. In none of them was the phenomenon was so pronounced that it sealed the nerve root completely
