The issue of post-mortem examination of animals, whose death occurred as a result of suffered gunshot wounds, is very rarely discussed in literature, most often on the occasion of researching into and describing other problems. This article presents an attempt to bring together the achievements of veterinary forensics in this area. As a starting point, the current legal regulation was adopted, pointing to penal sanctions resulting from the illegal use of weapons in relation to animals. Subsequently, the possibilities of using modern imaging techniques in post-mortem examinations carried out by veterinarians at the request of law enforcement agencies were presented. The scientific reports discussed herein have been supplemented by examples of sectional examinations carried out at the request of law enforcement agencies in Polish scientific institutions. The article indicates that the results of examination of gunshot wounds suffered by people in various circumstances may be used for the purpose of issuing forensic veterinary opinions, just as the results of examination of gunshot wounds of large mammals may be helpful in examining the effects of gunshot injuries in humans.

Submerged stone archaeological artefacts are bioeroded by endolithic microbiota (cyanobacteria, algae and fungi) and macroborers (Porifera, Bivalvia and Sipuncula). Optical microscope and SEM observations permit to analyse the bioerosion traces and to identify bioeroders. Data obtained with these techniques cannot be used to estimate volumes of material bioeroded. This aspect require the need to collect three-dimensional, close-range data from artefact. In this work we illustrate two 3D imaging techniques used to study bioerosion phenomena of underwater Cultural Heritage. In particular Digital Video Microscope permit the elaboration of 3D images, which are widely employed for close-range acquisitions. Underwater Laser Scanner documents the in situ degradation of submerged artefacts. This research aims to sensitize specialist figures in the study 3D offering a starting point for future collaborations that could lead to interesting results.

Starting Point

The clinical diagnosis of Alzheimer’s disease (AD) is based primarily on neuropsychological tests, which assess the involutive damage, and imaging techniques that evaluate morphologic changes in the brain. Currently available diagnostic tests do not show complete specificity and do not permit accurate differentiation between AD and other forms of senile dementia. The correlation of these tests with laboratory investigations based on biochemical parameters could increase the certainty of diagnosis. In recent years, several biochemical markers for the diagnosis of AD have been proposed, but in most cases they show a limited specificity and their application is invasive, requiring, in general, sampling of cerebrospinal fluid. Thus, the use of a peripheral biochemical marker could represent a valuable complement for the diagnosis of this disease. Several studies have shown a relationship between neurodegenerative disorders typical of the ageing process, weakening of the immune system and alterations in the levels of selenium and of the antioxidant selenoenzymes in brain tissues and blood cells. Among blood cells, neutrophil granulocytes uniquely express the selenoenzyme methionine sulfoxide reductase B1 (MsrB1). In a preliminary analysis carried out on neutrophils from subjects affected by AD, we observed a significant decline in MsrB1 activity compared to normal subjects. Therefore, we deem it of particular interest to explore the potential use of MsrB1 as a selective peripheral marker for the diagnosis of AD.

Abstract Background Aortitis is a heterogeneous rare condition causing aortic inflammation, often due to infectious or autoimmune aetiology. Its presentation, diagnosis and optimal management remain poorly understood, often requiring multidisciplinary input. With the advent of improved imaging techniques, an increasing number of radiology reports are identifying features of vasculitis necessitating clinical investigation. We investigated how cases identified on imaging with features of aortitis reflected clinical diagnosis and treatment. We further examined whether radiological detection of aortitis enables more rapid management decisions to improve outcomes. Methods A search was conducted of all radiology reports from St George’s Hospital between 2008 and 2018 for key words indicating “aortitis”, including ‘hyperintense vessel uptake’ and ‘periaortic inflammation.’ From 15,963 initial results, 80 reports were identified with radiological suspicion of aortitis. Results Of 80 cases, 36/80 were diagnosed with autoimmune or idiopathic inflammatory pathology: 9 retroperitoneal fibrosis, 8 idiopathic, 7 Takayasu’s, 4 giant cell arteritis, 2 inflammatory aneurysms, 2 Behçet's, 2 IgG4 disease, 1 lupus, 1 granulomatosis with polyangiitis. Diagnosis of autoimmune or idiopathic aortitis was based on symptomatology, imaging, serology, vessel biopsy, and treatment response. 14/80 had infective aortitis: 11 had positive microbiology and 3 demonstrated empirical antibiotic response. Table 1 shows demographics. 12/80 had atheromatous disease. 18/80 were not further investigated due to comorbidity, lack of correlation with symptoms, or absence of follow-up. Initial imaging modalities with the highest yield were computed tomography (CTs) with aorta protocols and CTs of thorax/abdomen/pelvis. The most useful radiology report terms included: aortitis, periaortic inflammation, Takayasu’s, and hyperintense vessel uptake. Conclusion Our study is the first retrospective case analysis, to our knowledge, of more than 15,000 radiology reports used as a starting point to evaluate for aortitis, identifying a large dataset with a broad case-mix. It contrasts with current literature identifying cases histologically and post-operatively. We found that radiology can be a useful early alert for possible diagnoses which require further assessment. Consequently, we developed an alerting system within our radiology department based on the search terms and imaging modalities identified. This links to a multidisciplinary meeting including vascular and rheumatology, so highlighted cases are discussed early. Disclosures K. Townsend: None. G. Cattini: None. K. Moss: None. K.
