Knowledge and Awareness of CT Radiation Dose and Risk Among Patients

The study aims to assess the level of patients’ awareness and knowledge regarding radiation and dosage along with the associated risks from computed tomography (CT) scan. This cross-sectional study used questionnaires, which were distributed to the diagnostic imaging departments of six large local hospitals in Jordan between September 2014 and March 2015. A total of 600 patients completed the questionnaire, out of which, 52.33% of respondents were female and 47.6% male. The findings show insignificant effects of gender on patient’s knowledge ( P = .596) and significant effect of employment and profession on positive scores ( P = .000). Similarly, no statistical differences were found between gender and correct answers ( P = .707). This cohort of patients demonstrated a lack of awareness and knowledge about the use of ionizing radiation for diagnostic imaging. Thus, there may exist a similar lack of information that will require imaging professionals to raise patients’ awareness and offer them the appropriate information.

AIM: The purpose of the study was to evaluate the knowledge of referring physicians of general practitioners, residents, and medical specialists in Jordan and the Middle East on radiation dose and its impact on vulnerable patients. MATERIALS AND METHODS: The Institutional Review Board approved this study before data collection. A cross-sectional study employed questionnaire that was distributed to respondents (n = 293) of general practitioners, residents, specialists, and therapists. The questionnaire consisted of 29 questions. Nine questions concerned with demographics and the remaining 20 questions were divided into five sections: Radiation dose, ionizing radiation, pediatric radiation, pregnant women radiation, and radiation risks. The mean score was computed out of 20. Chi-squared test of independence was utilized to analyze each question. To compare the responses between the demographic variables groups, Kruskal–Wallis and Mann–Whitney tests were used. RESULTS: Out of the 293 respondents, 128 (43.7%) were aware of radiation. The average score of the questionnaire was 9.5 out of 20 (47.5%). Within each section, the level of knowledge varied. Physicians had the highest level of knowledge in radiation risk (85.7%) followed by ionizing radiation (62.1%). The questionnaire revealed lower levels of knowledge in the areas of pediatric radiation, pregnant women radiation, and radiation dose. The percentages of respondents, (with fair to good level of knowledge), were 47.1%, 34.5%, and 24.6%, respectively. CONCLUSION: The results of this study were consistent with previous studies that demonstrated a poor level of general knowledge in referring physicians regarding radiation dose, ionizing radiation, pediatric radiation, pregnant women radiation, and radiation risks.

Tomography Scan

Background. Cerebral palsy is one of the common childhood neurological problem which occurs due to defect or lesion in immature brain. The worldwide incidence of cerebral palsy is approximately 2-2.5 per 1000 live births. There have been many works on the role of computed tomography scan in the diagnosis of cerebral palsy. Objective: The objective information available from careful review of imaging information such as CT brain scans, is an important adjunct to clinical data. Materials and Methods: This cross sectional study was carried out in the department of Radiology and Imaging, BSMMU and department of Paediatric Neurology unit over a period of 12 months from January 2019 to December 2019. We calculated the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CT scan in diagnosis of CP in children. Results: This cross sectional study was carried out on consecutively selected 94 children below 15 years having clinical evidence of cerebral palsy. Among the study subjects 86.2% were diagnosed as cerebral palsy through CT scan. Conclusion: The sensitivity and specificity of CT scan of present study was found to be quite high in children which suggests a CT scan as an effective investigation for the diagnosis of cerebral palsy.

Exposed Workers

Background: Thyroid diseases occur more frequently in people exposed to ionizing radiation, but the relationship between occupational exposure to ionizing radiation and thyroid pathologies still remains unclear. Objective: To evaluate the prevalence of thyroid diseases in healthcare workers exposed to low-level ionizing radiation compared with a control group working at the University Hospital of Bari, Southern Italy, and living in the same geographical area, characterized by mild iodine deficiency. Methods: We ran a cross-sectional study to investigate whether healthcare workers exposed to ionizing radiation had a higher prevalence of thyroid diseases. Four hundred and forty-four exposed healthcare workers (241 more exposed, or “A Category”, and 203 less exposed, or “B Category”) and 614 nonexposed healthcare workers were enrolled during a routine examination at the Occupational Health Unit. They were asked to fill in an anamnestic questionnaire and undergo a physical examination, serum determination of fT3, fT4 and TSH, anti-TPO ab and anti-TG ab and ultrasound neck scan. Thyroid nodules were submitted to fine needle aspiration biopsy when indicated. Results: The prevalence of thyroid diseases was statistically higher in the exposed workers compared to controls (40% vs 29%, adPR 1.65; IC95% 1.34-2.07). In particular, the thyroid nodularity prevalence in the exposed group was approximately twice as high as that in the controls (29% vs 13%; adPR 2.83; IC95% 2.12-3.8). No statistically significant association was found between exposure to ionizing radiation and other thyroid diseases. Conclusion: In our study, mild ionizing radiation-exposed healthcare workers had a statistically higher prevalence of thyroid diseases than the control group. The results are likely due to a closer and more meticulous health surveillance programme carried out in the ionising radiation-exposed workers, allowing them to identify thyroid alterations earlier than non-exposed health staff.

Bone Graft Harvesting

Abstract Background Bone volume plays a pivotal role in the success of dental implant treatment. Autogenous bone grafts should be harvested from reliable sites in the maxillofacial region. This study sought to assess the quantity and quality of bone in the mandibular symphysis for autogenous bone graft harvesting using cone-beam computed tomography (CBCT). Methods This cross-sectional study evaluated the CBCT scans of 78 adults presenting to three oral and maxillofacial radiology centers. The vertical (VD) and horizontal (HD) alveolar bone dimensions, cortical thickness (CT), and cancellous to cortical bone ratio (C/C) were measured in the interforaminal region of the mandible at the sites of central incisor to first premolar teeth. The interforaminal distance (ID) and the anterior loop length were also measured. Nonparametric statistical tests were used to analyze the data with respect to sex, age, and tooth position. Results The median VD, HD, and CT of the symphysis were 20.21 (3.26), 4.13 (0.37), and 2.25 (0.23) mm, respectively. The median C/C was 1.51 (0.11). The median ID was 52.24 (8.24) mm, and the median anterior loop length was 1.82 (1.06) mm. Significant differences were observed in all parameters among different teeth. Most of the measured parameters were greater in males compared with females. There were significant differences in ID, VD, and CT between different age groups. Conclusions The quantity and quality of the available bone in the mandibular symphysis for bone graft harvesting vary by gender, age, and harvesting site, necessitating careful preoperative evaluation.

Obstetric Violence

Background: Obstetric violence is a worldwide public health problem, which seems greater in Spain. As no studies were found that identify the most representative healthcare professionals, times, and areas involved in obstetric violence, the objective of this work was to study at what time of maternity, with which professionals, and in what areas women identified obstetric violence. Methods: This descriptive, retrospective, and cross-sectional study was performed from January 2018 to June 2019. The main variables were the area (hospital, primary care, both), the time (pregnancy, birth, puerperium), and the professionals attending to women. Results: Our sample comprised 17,541 participants. The area identified with the most obstetric violence for the different studied variables was hospitals. Women identified more obstetric violence at time of birth. Findings such as lack of information and informed consent (74.2%), and criticism of infantile behavior and treatment (87.6%), stood out. The main identified healthcare professionals were midwives and gynecologists, and “other” professionals repeatedly appeared. Conclusions: Having identified the professionals, times, and areas of most obstetric violence in Spain, it seems necessary to reflect on not only the Spanish National Health System’s structure and management but also on healthcare professionals’ training.
