Chest CT in COVID-19 Pneumonia: Potentials and Limitations of Radiomics and Artificial Intelligence
2021
SARS-CoV-2 epidemics has resulted in an unprecedented global health crisis causing a high number of deaths with pneumonia being the most common manifestation. Chest CT is the best imaging modality to identify pulmonary involvement, but unfortunately there are no pathognomonic features for COVID-19 pneumonia, since many other infectious and non-infectious diseases may cause similar alterations. The adoption of artificial intelligence in biomedical imaging has the potential to revolutionize the identification, management, and the patient’s outcome. If adequately validated, it could be used as a support with predictive and prognostic purposes in symptomatic patients but also as a screening tes…
Clinical repercussions and epidemiological considerations of supernumerary canines : a 26 case series
2019
Background To establish the prevalence of supernumerary canines (SNC) in a sector of the population of Madrid (Spain), as well possible complications associated with this unusual developmental variation. Material and Methods This observational study was performed between 2005 and 2017, among 21,615 patients seeking dental treatment at the Faculty of Dentistry, Complutense University of Madrid (Spain), and at the Virgen de la Paloma Hospital, Madrid (Spain); 22 patients with 26 SNCs were diagnosed. These 22 patients underwent clinical and radiological exploration, registering patient data. Results SNCs presented a prevalence of 0.10% of the study population. The supernumerary teeth (SNT) wer…
Overdiagnosis and overimaging: an ethical issue for radiological protection
2019
Aims and objectives: This study aimed to analyse the key factors that influence the overimaging using X-ray such as self-referral, defensive medicine and duplicate imaging studies and to emphasize the ethical problem that derives from it. Materials and methods: In this study, we focused on the more frequent sources of overdiagnosis such as the total-body CT, proposed in the form of screening in both public and private sector, the choice of the most sensitive test for each pathology such as pulmonary embolism, ultrasound investigations mostly of the thyroid and of the prostate and MR examinations, especially of the musculoskeletal system. Results: The direct follow of overdiagnosis and overi…
Errors in imaging patients in the emergency setting
2016
Emergency and trauma care produces a "perfect storm" for radiological errors: uncooperative patients, inadequate histories, time-critical decisions, concurrent tasks and often junior personnel working after hours in busy emergency departments. The main cause of diagnostic errors in the emergency department is the failure to correctly interpret radiographs, and the majority of diagnoses missed on radiographs are fractures. Missed diagnoses potentially have important consequences for patients, clinicians and radiologists. Radiologists play a pivotal role in the diagnostic assessment of polytrauma patients and of patients with non-traumatic craniothoracoabdominal emergencies, and key elements …
Towards “global zero”: the role of the Holy See in the campaign on nuclear disarmament
2019
On 7 July 2017 at the UN headquarters in New York the Treaty on the Prohibition of Nuclear Weapons was adopted, the first multilateral legally-binding instrument for nuclear disarmament negotiated in the last twenty years. The very signing of the Treaty must be seen as an extraordinary achievement because it represents a historic step in the seven decades long debate on nuclear weapons. One of the most significant achievements of the decade-long campaign is the engagement of civil society and non-state actors to such a degree that it was recognized through the awarding of the Nobel Peace Prize to the International Campaign to Abolish Nuclear Weapons (ICAN). The crucial supporter of the cam…
Attitudes concerning nuclear war in finland and in the united states
1986
Four hundred seventy residents of Ridgewood, New Jersey, and 493 residents of Jyvaskyla, Finland, were randomly selected and interviewed about their attitudes concerning nuclear war. In both areas, a high proportion of the samples believed that some kind of nuclear incident is likely in the next decade. The vast majority stated that a nuclear war could not be won and that they expected to die in the event of war. About three fourths in both communities seldom discuss nuclear issues with anyone including their own children, and only one fourth of the U.S sample and about one half of the Finnish sample have ever done anything personally to oppose the arms race. About one half of the Americans…
FUZZY RISK ANALYSIS OF A MODERN γ-RAY INDUSTRIAL IRRADIATOR
2011
Fuzzy fault tree analyses were used to investigate accident scenarios that involve radiological exposure to operators working in industrial γ-ray irradiation facilities. The HEART method, a first generation human reliability analysis method, was used to evaluate the probability of adverse human error in these analyses. This technique was modified on the basis of fuzzy set theory to more directly take into account the uncertainties in the error-promoting factors on which the methodology is based. Moreover, with regard to some identified accident scenarios, fuzzy radiological exposure risk, expressed in terms of potential annual death, was evaluated. The calculated fuzzy risks for the examine…
Clinical and radiological features of Forestier's disease presenting with dysphagia
2018
Background Diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier's disease, is a rheumatologic condition characterized by ossification of the spinal ligaments and tendons. Large anterior osteophytes are typically present in the lower cervical levels, while upper cervical ossification resulting in dysphagia is very rare. Methods Here, we presented a patient with Forestier's disease involving massive ossification of the anterior longitudinal ligament extending from C3 to C4 downward contributing to severe dysphagia. Results A 65-year-old male presented with cervical pain and dysphagia. The computed tomography of the cervical spine demonstrated massive anterior longitudinal …
La panoplia en los vasos del Tossal de Sant Miquel (Llíria). Ensayo de interpretación iconográfica
2013
The set of more than 225 vases with figurative decoration found in El Tossal de Sant Miquel (TSM), Lliria, with a chronology that it is fitted in the second stage of the Middle Iberian, between IIIrd century B.C. at the beginning of the IInd B. C, and published by first time in the Corpus Vasorum Hispanorum, offers a rich iconography in arms elements. Across his analysis it is tried to determine if a edetana panoply exists and if this one changes according to so called «Styles I and II». (Ballester, 1935, 1954; Bonet, 1995; Aranegui et alii, 1997b; Pérez Ballester, Mata, 1998; Izquierdo, Perez Ballester, 2005).El conjunto de más de 225 vasos con decoración figurada encontrados en El Tossal …
Immediate post-extraction implants placed in acute periapical infected sites with immediate prosthetic provisionalization : a 1-year prospective coho…
2020
Background Few studies have reported the outcomes of immediate placement at infected post-extraction sites. The aim of this study was to compare clinical and radiological outcomes of immediately placed implants with immediate prosthetic provisionalization in sockets with or without acute periapical pathology. Material and Methods A total of 100 patients with immediately placed implants with immediate provisionalization and 1- year of follow up were included (50 patients with acute periapical pathology and a control group of 50 patients without acute periapical pathology). Clinical parameters (bleeding on probing, buccal keratinized mucosa width, clinical recession, and probing depth) and ra…
