Background: One of the most harmful agents in hospital settings is ionizing radiation such as X-rays that physicians and other staff expose in surgeries and diagnostic tests. Therefore, the aim of this study was to measure X-ray dose in the diagnostic radiology units of hospitals affiliated to North Khorasan University of Medical Sciences. Methods: This is a descriptive-analytical, cross-sectional study, in which all of the hospitals' diagnostic radiology units including CT scan, mammography, fluoroscopy and radiography were studied. X-ray dose was measured by a dosimeter-radiometer device (MKS-05 Terra-P). The International Radiation Protection Association (IAEA) checklist was used to check the observance of the Radiation Protection Principles. Results: The results of this study showed that the X-ray doses in the CT scan, mammography, and fluoroscopy units of Bojnord Imam Ali Hospital were 0.16, 0.08 and 0.01 μSv/h, respectively. The doses of X-ray in the radiology units of Imam Ali (PBUH), Imam Reza (PBUH), Esfarayen and Shirvan Hospitals were 0.12, 0.12, 0.11, and 0.11 μSv/h, respectively. Conclusion: According to the results, the X-ray doses in the diagnostic radiology units of hospitals were lower than the standard limit proposed by the International Radiation Protection Association. However, it is proposed to use appropriate protective lead aprons to further protect the exposed staff in the units in question.

Objective: To study clinical symptoms and chest X-ray findings for evaluation of chest X-ray in management ofconfirmed cases of COVID-19 and predicting the clinical outcome. Study Design: Cross sectional study. Place and Duration of Study: The departments of Radiology & Medicine of Combined Military Hospital Malir,from Mar to May 2020. Methodology: The sample used in this study consists of 73 patients. All the standard frontal projections of chest X-ray of PCR confirmed COVID-19 patients were studied on computer and findings were noted Results: At the aggregate, the study indicates that there is no Significant Connection in between the clinicalsymptoms, their severity and chest X-ray findings. Conclusion: There is no significant connection found between the severity of clinical symptoms and chest X-rays suggesting that chest X-Ray cannot be a reliable indicator to predict the clinical outcome of the patient and has limited role in management of patient. Clinical assessment is still the main stay of the patient management.

Abstract Introduction Anecdotal evidence suggests that medical professionals in trauma units are requesting additional regional images using conventional x-ray systems, even after trauma patients have undergone full-body Lodox scans. Patients are then exposed to additional radiation, additional waiting times and an increased medical bill. This study aimed at investigating the extent to which Lodox systems were used in trauma units (n=28) in South Africa. Method In this descriptive cross-sectional study, the researcher invited one radiographer from the 28 hospitals in South Africa that use Lodox systems. Radiographers who were most experienced in using the Lodox system completed an online questionnaire. Results Twenty (71.43% n=20) out of twenty-eight radiographers responded. Most hospitals (90%, n=18) were referring patients for additional conventional x-ray images. Radiographers indicated that conventional x-rays were requested for the chest (27.80%, 10/36), the abdomen (16.67%, 6/36), the spine (13.89%, 5/36) and the extremities and skull (19.44%, 7/36). Additionally, radiographers reported using Lodox to perform procedures and examinations usually performed on conventional x-ray systems when conventional x-ray systems were not operational. Conclusion Currently, it is not clear if the use of conventional x-ray imaging following Lodox is necessary, but the results suggest that the practice is commonplace, with healthcare workers in most hospitals (90%, n=18) requesting additional x-ray imaging. The researcher thus recommends that an imaging protocol for Lodox imaging systems should be developed to guide the referral of the patients for further imaging.

Degenerative Processes

Brain alterations have been sought since the beginning of the century to explain the ‘dementia’ of dementia præcox. Kraepelin suggested in 1913 that it might have its internal origins in early childhood, while Southard (1915) considered likely a congenital or early acquired basis for the development of the disease. Afterwards, degenerative processes were described for decades until neurodevelopmental theories emerged recently (Lewis, 1988).Using pneumoencephalography, Jacobi and Winkler (1927) first reported that some patients with schizophrenia presented enlarged ventricles. Johnstone et al (1976, 1978), in CT-scan studies, observed an increase in mean lateral ventricular size in a group of institutionalized schizophrenic patients. This finding has been replicated by other studies (Weinberger et al, 1983) but challenged by others (Gluck et al, 1980; Jernigan et al, 1982).

Despite many advances in the diagnosis, screening, and rapid treatment of tuberculosis, it is still a public health concern in the world. Due to the importance of this issue in diagnosis and reduction of transmission of infection and treatment of the disease especially where this study is conducted due to the high prevalence of tuberculosis, this study was done to determine The relationship between sputum smear positivity grade and chest X-ray findings in pulmonary tuberculosis patients in a hospital in southeast of Iran. This cross-sectional study was performed on all patients with pulmonary TB referencing the health centers in Zabol city, southeast of Iran from 1 January 2015 to 30 December 2020. Sputum smear and radiographic findings of the chest X-ray were evaluated. Data was collected using a form of information and finally analyzed by SPSS 22. Out of 101 patients examined in the present study, 71 were women and 30 were men. The mean age of the patients was 62.68 ± 13.61 years. The frequency of opacity in patients with grades 1, 2, and 3 was 71.4, 78.5, and 76.5%, respectively. Frequency of cavitation in patients with Grade 1, 2 and 3 was 11.5%, 28.5% and 52.9% respectively (P value 0.001). The frequency of reticulonodular presentations in patients with grade 1, 2, and 3 was 24.2, 7.1, and 0%, respectively.  In general, the results of this study showed that, with increasing grading of smears (1+, 2+, and 3+), the frequency of cavitation presentation increased significantly and the frequency of reticulonodular presentations decreased significantly. In general, the results of this study showed that, with increasing grading of smears (, the frequency of Cavitation presentation increased significantly and the frequency of reticulonodular presentations decreased significantly. The findings of the present study can help physicians better diagnose TB.
