Computed tomography abnormalities in hanging
No full textAbstract
The CT pattern of bilateral and symmetrical round low density areas in the globi pallidi has been observed in a young man who attempted suicide by hanging. These CT abnormalities are similar to those described in other conditions such as carbon monoxide, hydrogen sulfide, cyanide and methanol poisoning, hypoglycaemia, drowning and acute global central nervous system hypoperfusion. The findings appear to be correlated with acute cerebral hypoxia
MRI appearances consistent with haemorrhagic infarction as an early manifestation of carbon monoxide poisoning
No full textAbstract
High signal in the globus pallidus on T1-weighted images was observed in two patients who underwent early MRI, after exposure to carbon monoxide (CO). We compare these MRI abnormalities with those previously reported, and with CT findings which suggested that the damage to the globi pallidi is of vascular origin. We discuss also the hypothesis that haemorrhagic infarction is an early manifestation of CO poisoning
Transient disappearance of bilateral low-density lesions of the globi pallidi in carbon monoxide intoxication and MRI

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
Sardinian Museum of Anthropology and Ethnography: A Case of Ankylosing Spondylitis from Sardinia

No full textIl Museo fu fondato nel 1953 dal medico antropologo Carlo Maxia, contemporaneamente all’Istituto di Antropologia come museo ad esso annesso. La sede storica era ubicata nel centro di Cagliari mentre ora si trova nella Cittadella Universitaria di Monserrato. Dalla fondazione del museo e sino alla fine degli anni ‘70 Maxia raccolse reperti relativi alla preistoria e alla protostoria sarda, promosse eventi internazionali, stabilì contatti culturali grazie ad un’intensa attività di viaggiatore, visitando Africa, Australia, America Latina, Asia da cui riportò ampia documentazione. Pubblicò svariati lavori su aspetti paleobiologici, patologici e culturali della Sardegna. Tra le collezioni spiccano quella osteologica e quella di abiti tradizionali. La prima si è arricchita nel tempo, grazie all’impegno degli scriventi, ed è ora punto di riferimento per ricercatori italiani e stranieri. Sono in atto collaborazioni nazionali ed internazionali e partecipazioni a progetti multimediali.The museum was founded in 1953 by medical anthropologist Charles Maxia. The historic site was located in the
center of Cagliari and is now in the University Campus of Monserrato. Since the founding of the museum until
the end of the 70s Maxia collected artifacts relating to the prehistory and early history of Sardinia. He promoted
international events and established cultural contacts: he visited Africa, Australia, Latin America, Asia. He
published several works on paleobiologic and pathological aspects of Sardinian people. The bone collection and
that of traditional clothing are among the most important. The first has been enriched over time and is now a
reference point for Italian and foreign researchers. The museum collaborates with national and international
organizations and is involved in several multimedia projects

No full textThe specimen presented here is part of the remains of
several individuals recovered after a random discovery
in 1974-1975 in the collapsed natural dome near Su
Sercone (Orgosolo, NU, central Sardinia, IT) by G.
Cosseddu, then professor at the Institute of Anthropology,
Cagliari University. It is a spinal cord fully fused, with bone
production involving also a large part of the pelvis, which
can be diagnosed as ankylosing spondylitis. Only recently it
was handled and prepared to allow its study.
Materials and Methods
Methods were those typically applied on macroscopic
traits, both metric and non-metric (as in Martin and Saller,
1957-62). Identifi cation of pathology follows Ortner
and Putschar (1985) and Aufderhide and Martin (1998),
whereas stress markers were detected after Mariotti et al.
(2007).
A macroscopic examination has been carried out, with
the analysis of the paleopathological conditions of the
remain, and subsequently an X-ray completed the analysis.
The specimen has then been investigated through x-rays
at the “Laboratorio di Diagnostica per immagini” at the
University’s Policlinico, in Monserrato. The specimen
belongs to an individual of unknown age, since the
diagnostic bone surfaces were altered by its pathological
condition.
In 1992 it was submitted for 14C analysis for absolute
dating (Beta Analytics Inc., Miami, Florida). Its overall length
is 31 cm. Ankylosis affects the whole spinal cord, including
the sacroiliac joints, presumably also in the left side. There
is rib ossifi cation in in T1 and T2 (Fig. 1) and a remarkable
scholiosis. Evident signs of an ante mortem fracture that
leads to hypothesize fusion also in the atlas-occipital
articulation. Th
