Congenital colonic stenosis is a rare pediatric condition. Since 1968, only 16 cases have been reported in the literature. To the authors’ knowledge, multiple congenital colonic stenosis has not been previously reported in the literature. We report the case of a 2-month-old male, presented at our Neonatal Intensive Care Unit with a suspicion of intestinal malrotation. Clinical examination revealed persistent abdominal distension. During the enema examination, the contrast medium appeared to fill the lumen of the colon up to three stenotic segments and could not proceed further. Intraoperatively we confirmed the presence of four types of colonic atresia, located in the ascending, transverse, and descending colon, respectively, plus appendix atresia. First surgical steps consisted in resection of proximal stenotic segment, appendix removal, proximal cecostomy, and distal colostomy on ascending colon in order to preserve colonic length. Histopathological examination confirmed the diagnosis of colonic stenosis. Final surgical step consisted in multiple colocolostomy and enteroplasty. A planned two-stage procedure, consisting of resection with colostomy for decompression as the first step and a later anastomosis, is recommended in order to allow bowel length preservation.

The changes introduced with Council Directive 2013/59/Euratom will require European Member States adapt their regulations, procedures and equipment to the new high standards of radiation safety. These new requirements will have an impact, in particular, on the radiology community (including medical physics experts) and on industry. Relevant changes include new definitions, a new dose limit for the eye lens, non-medical imaging exposures, procedures in asymptomatic individuals, the use and regular review of diagnostic reference levels (including interventional procedures), dosimetric information in imaging systems and its transfer to the examination report, new requirements on responsibilities, the registry and analysis of accidental or unintended exposure and population dose evaluation (based on age and gender distribution). Furthermore, the Directive emphasises the need for justification of medical exposure (including asymptomatic individuals), introduces requirements concerning patient information and strengthens those for recording and reporting doses from radiological procedures, the use of diagnostic reference levels, the availability of dose-indicating devices and the improved role and support of the medical physics experts in imaging.

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 overimaging is the increase in the risk of contrast media infusion, radiant damage, and costs in the worldwide healthcare system. The theme of the costs of overdiagnosis is strongly related to inappropriate or poorly appropriate imaging examination. Conclusions: We underline the ethical imperatives of trust and right conduct, because the major ethical problems in radiology emerge in the justification of medical exposures of patients in the practice. A close cooperation and collaboration across all the physicians responsible for patient care in requiring imaging examination is also important, balancing possible ionizing radiation disadvantages and patient benefits in terms of care.

Objective: The aim of this study was to acknowledge errors in patients positioning in CT colonography (CTC) and their effect in radiation exposure. Materials and methods: CTC studies of a total of 199 patients coming from two different referral hospitals were retrospectively reviewed. Two parameters have been considered for the analysis: patient position in relation to gantry isocentre and scan length related to the area of interest. CTDI vol and DLP were extracted for each patient. In order to evaluate the estimated effective total dose and the dose to various organs, we used the CT-EXPO ® software version 2.2. This software provides estimates of effective dose and doses to the other various organs. Results: Average value of the patients’ position is found to be below the isocentre for 48 ± 25mm and 29 ± 27mm in the prone and supine position. It was observed that the increase in CTDI and DLP values for patients in Group 1, due to the inaccurate positioning, was estimated at about 30% and 20% for prone and supine position, respectively, while in Group 2, a decrease in CTDI and DLP values was estimated at about 16% and 18% for prone and supine position, respectively, due to an average position above isocentre. A dose increase ranging from 4 up to 13% was calculated with increasing the over-scanned region below anal orifice. Conclusion: Radiographers and radiologists need to be aware of dose variation and noise effects on vertical positioning and over-scanning. More accurate training need to be achieved even so when examination protocol varies from general practice.

Burnout syndrome is a condition that may occur not only for staff in human service sectors/jobs, involving intensive interactions with others, but also people that are engaged in activities psychologically similar to work, such as students. Radiographers in training suffer double stress, first linked to the status of being a university student and secondly as early career workers who have relations with the public of the health system. Aim of our study was to investigate the prevalence and levels of burnout syndrome among radiographers in training in an University Hospital.In order to gain a better understanding of nature of the burnout syndrome a modified version of Maslach's questionnaire (investigating three areas: emotional exhaustion, depersonalization and reduced personal accomplishment), was administered to two groups selected from a cohort of radiographers University students (from the 1st and 3rd year of course).62/62 questionnaires were completed, returned and analysed. The research outcomes highlighted a clear difference between group I and group II in relation to one of the three areas of the Maslach's model: "depersonalization" (p0.001). Moreover, the third year students group presented a significantly higher risk to develop burnout. On the other hand, the third area examined, the reduced personal accomplishment domain, was surprisingly high even among first-year students.The research outcomes seem to suggest that the presence of emotional burnout, or risk of burnout, among third year students is statistically significant, compared to the first year students, being a significant aspect to investigate further in this class of students. It is also assumed that the high degree of "past failures, feeling of self failure" observed among all student, is related to a feeling of poor efficacy and poor self worth that appear to grow from the beginning of the course. This topic needs further investigation in the light of the result of this study.Scopo. Il burnout è una sindrome che può interessare operatori e professionisti che sono impegnati quotidianamente e ripetutamente in attività che implicano le relazioni interpersonali, lavorando a stretto contatto con il pubblico, ma anche persone impegnate in attività psicologicamente simili al lavoro, come gli studenti. Gli studenti di tecniche di radiologia sono sottoposti ad un doppio stress, sia a quello legato allo stato di studente, che a quello legato allo stato di lavoratore a contatto con il pubblico durante il loro periodo di tirocinio professionale. Scopo del nostro studio è stato quello di investigare la prevalenza della sindrome da burnout tra i tecnici di radiologia in formazione in un Ospedale Universitario. Metodi. Per ottenere una migliore comprensione della natura della sindrome da burnout è stato somministrata una versione modificata del questionario di Maslach (che investiga 3 aree: esaurimento emotivo, depersonalizzazione e ridotta realizzazione personale) a 2 sottogruppi selezionati da una coorte di studenti Universitari in tecniche di radiologia (del 1° e 3° anno di corso). Risultati. Sono stati completati, consegnati ed analizzati 62/62 questionari. I risultati della ricerca hanno evidenziato una chiara differenza tra i 2 gruppi in una delle tre aree del modello di Maslach: la “depersonalizzazione”. Inoltre, la terza area esaminata, la ridotta realizzazione personale, è risultata sorprendentemente elevata anche tra gli studenti di primo anno. Conclusioni. I risultati della ricerca suggeriscono che la presenza di burnout emozionale, o il rischio di burnout, tra gli studenti del terzo anno sia statisticamente significativa se confrontata con i risultati degli studenti del primo anno di corso, rendendolo un aspetto da investigare più a fondo in questa classe di studenti. Si suppone che l’alto livello di senso di fallimento personale osservato tra gli studenti, sia correlato con un sentimento di scarsa autostima che sembra crescere dall’inizio del corso.

Current radiological literature is strongly focussed on radiation imaging risks. Indeed, given there is a small but actual augment in cancer risk from exposure to ionizing radiation in children, it is important to understand what the risk of alternative techniques could be. We retrospectively review literature data concerning possible MR imaging risks, focussing on the biological effects of MR, sedation and gadolinium compound risks when dealing with infant patients. The main concerns can be summarized in: (1) Biological effects of non-ionizing electromagnetic fields (EMF) employed—whose mechanisms of interaction with human tissues are polarization, induced current, and thermal heating, respectively. (2) Risks associated with noises produced during MRI examinations. (3) Hazards from ferromagnetic external and/or implanted devices—whose risk of being unintentionally brought inside MR room is higher in children than in adults. (4) Risks associated with sedation or general anaesthesia, essential problem in performing MR in very young patients, due to the exam long-lasting. (5) Risks related to gadolinium-based contrast agents, especially considering the newly reported brain deposition.
