Tuberous sclerosis (TS) is a rare genetic disorder of autosomal-dominant inheritance. Mutations on either of the two genes Tuberous Sclerosis Complex 1 (TSC1) or Tuberous Sclerosis Complex 2 (TSC2) play a role and result in hamartomas involving many organs, like the brain, heart, kidneys, skin, lungs, and liver. This case report is about a four-year-old boy with facial angiofibromas, hypo-pigmented skin lesions on the lower back and dorsum of the right wrist, and previous history of seizures who was referred to the radiology department of the Korle Bu Teaching Hospital for Magnetic Resonance Imaging (MRI) of the brain. The MRI of the brain revealed subependymal giant cell astrocytomas, subependymal nodules, and cortical tubers. Ultrasonography of the abdomen also showed multiple angiomyolipomas and multiple simple cysts in both kidneys. The aim of this case report is to present the imaging findings and create awareness that this rare genetic disorder does exist in Ghana and advocate for formation of support groups for parents with children with tuberous sclerosis.
ObjectiveThe aim of the present study was to assess current MRI safety practices among MRI facilities in Ghana, and their compliance with the 2013 American College of Radiology (ACR) guidance document on MR safe practices.Material and methodsA questionnaire developed from the 2013 ACR Guidance Document was used to collect information on magnetic field strengths, MR safety policy and compliance, patient screening, emergency preparedness, infection control, MRI safety accessories, equipment safety, signage and barriers, report of adverse incidents, and access and communication.ResultsOut of the 13 MRI facilities identified, response rate of 92% was obtained. Six (50%) facilities indicated they have MRI safety policy and have it present and readily available to facility staff. Five (42%) facilities indicated they have handheld magnets, and 1(8%) has ferromagnetic detection system. Only one (8%) had crash carts. Seven (58%) facilities have zone 4 clearly marked with a red light and lighted sign stating “The Magnet is On”. One (8%) recorded projectile incident and fire outbreak. Eight (67%) facilities have direct visual observation of access corridors to zone IV.ConclusionThere was compliance in some areas of MRI safety practice, however there were some shortfalls which need to be addressed. We therefore recommend improvement in the following areas: (1) establishment, implementation, and maintenance of current MRI safety policy, (2) patient screening, (3) provision of training and routine drills on emergency response protocols with documentations, (4) emergency preparedness, and (5) provision of colour codes for equipment used within MRI environment.
A two-phased retrospective cross-sectional study analysed the occupational dose and radiation protection practice among medical workers in two hospitals in the UAE. Phase 1 evaluated radiation protection practice using a questionnaire, whereas phase 2 assessed the occupational dose. Readings of 952 thermoluminescence dosimeters were analyzed. The result showed 52% of medical workers have a good level of radiation protection practice. Readings of 952 thermoluminescence dosimeters were analyzedAverage annual effective dose per worker ranged from 0.39 to 0.83 mSv. Cardiologists and nurses displayed a higher average of occupational radiation dose compared to other workers. There were no significant correlations between radiation protection practice and hospital, occupation or department. Finally, the occupational dose was within the international and national limits, but the reduction of radiation dose to cardiologist and nurses is essential. Moreover, training is essential to promote radiation safe practice among medical workers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
