Abstract
INTRODUCTION Women presenting for mammography occasionally have pacemakers or other cardiac-implantable electronic devices (CIEDs) in situ. This research investigates Australian radiographers' awareness of CIEDs in the diagnostic and screening settings. METHODS A survey of radiographers with mammography experience in Australia was conducted using SurveyMonkey™. Respondents were asked if they could confidently identify images of devices and whether they had imaged them mammographically. A Chi-squared test of independence was used to compare the association between demographics and CIED awareness. A value of p < 0.05 was deemed statistically significant. RESULTS There were 220 valid responses. All CIED types had been imaged. Most respondents had imaged a pacemaker (94.5%) and implantable cardioverter-defibrillator (ICD) (85.6%), compared to the three different implantable loop recorders (ILRs) (ILR-1: 63.4%; ILR-2: 14.1%; and IRL-3: 26.9% and the emerging subcutaneous ICDs (S-ICDs) (11.9%). Most respondents felt confident identifying the pacemaker (95%) and the ICD (86.1%). Only 19.4% of respondents could confidently identify the emerging S-ICD. CONCLUSION A lack of awareness of new and emerging devices may impact approaches to imaging and present significant risk to patients. The lack of studies comprehensively describing devices and their mammographic appearance to support radiographers' knowledge and awareness highlights an urgent need to progress research in this area. IMPLICATIONS FOR PRACTICE As a part of continuing professional development, radiographers performing mammography must ensure they remain up to date with current and emerging technology, including CIEDs. This study has identified a lack of awareness of the different types of CIEDs currently being implanted and imaged, which may translate to unsafe imaging practices. There is an urgent need for further education to bridge this knowledge gap and ensure the safety of practice in imaging women with CIEDs. FOOTLINE Mammography: CIED Imaging.

Abstract
PURPOSE/OBJECTIVE(S) Stereotactic Radiosurgery (SRS) has been increasingly used as first and subsequent-line treatments for brain metastases. While the appropriate cut-off number of lesions for SRS is still being debated nationally in patients with multiple brain metastases, some institutions use an alternate approach particularly for patients with >10-15 lesions. Selected-lesion SRS (SL-SRS) is where only a subset of lesions are chosen for initial SRS treatment leaving small and clinically inconsequential lesions for treatment using alternate or delayed treatments. This study aims to investigate the patient selection criteria, patient and tumor characteristics and analyze the outcomes in patients receiving SL-SRS for brain metastases at our institution. MATERIALS/METHODS Clinical data from patients treated using the SL-SRS approach from 2012-2022 at our institution were retrospectively reviewed. Patients were divided into cohorts based on overall survival from time of SL-SRS treatment and indications for using SL-SRS. We compared the patient characteristics (age, histology, KPS, dsGPA), tumor characteristics (cumulative tumor volumes, tumor dose, number of brain metastases found, number of metastases treated), treatment characteristics (chemotherapy, immunotherapy, previous SRS/ radiation, previous WBRT) and the reason for decision to recommend SL-SRS across these cohort. RESULTS A total of 102 patients were treated using the SL-SRS approach. Indications for using SL-SRS were immunotherapy trial (n = 40), CNS penetrating drug options available (n = 18), patient refusing WBRT (n = 6), palliative after prior WBRT/SRS (n = 28), WBRT planned to follow SRS (n = 9). 31 patients were alive at 12 months and 21 patients at 24 months. In patients surviving <12 months - the most common indications for SL-SRS were CNS palliation in the setting of progressive disease after prior WBRT or SRS. Patients in this group had median KPS< = 60 and had predominantly non-small cell carcinoma primary diagnosis. In those patients surviving >12 months - the most common indication for SL-SRS was participation in CNS-penetrant agent clinical trials without WBRT. Patients in this group were more likely to be female, had a median KPS of 90, had predominantly diagnoses of melanoma. Following the SL-SRS treatment, 14 patients required further SRS and 4 patients went on to WBRT in the >12-month survival group. No patients died of CNS progression alone. 10 patients survived 24 months without requiring further CNS radiation. CONCLUSION In our institution, SL-SRS has predominantly been used either as palliative treatment at time of disease progression or to facilitate entry onto clinical trial with immunotherapy or potentially CNS-penetrant agents. The latter indication resulted in 47.6% patients surviving >24 month without the need for additional radiation to the CNS and therefore SL-SRS should be considered a feasible, safe and effective alternative to either WBRT or SRS treatment of all radiographically visible brain metastases.

Abstract
PURPOSE/OBJECTIVE(S) With the increasing use of intracranial SRS (SRS) for treatment of patients with >10-15 brain metastases treatment; debate remains in the literature about how these patients should be treated. While many advocate for treatment of all lesions with either SRS or whole brain radiation therapy (WBRT), several groups are considering selected-lesion SRS (SL-SRS) where only a subset of intracranial lesions are treated. However, the current practice patterns of SL-SRS are not known. MATERIALS/METHODS A survey of 19 questions was created using open-ended and multiple-choice style questions on SL-SRS practices and indications. The survey was distributed to providers in the US and internationally who perform SRS frequently. Ten out of 50 institutions provided responses reflecting the practices of 16 providers. Descriptive statistics was used to compare answers to each question when applicable including percentages and ranges. RESULTS SL-SRS was performed at 8/10 institutions, (5 out of 6 US institutions and 3 out of 4 international institutions). Only 2 institutions had established clinical indications for SL-SRS (one in the US and one internationally) and one additional US institution reported clinical trials that require SL-SRS to study efficacy of CNS penetrating targeted therapies. One program reported research protocols for untreated brain metastases that would take priority over SL-SRS (program outside the US). Size of the lesion was cited as the most important factor (90%) when deciding to treat any single lesion. Next, lesion location and focal signs/symptoms were both considered moderately important. 80% ranked distance from prior SRS as the least important factor. Perilesional edema was also less important at most programs (90%). Lesion location and presence of symptoms were also considered important. There were several factors that would encourage providers to consider SL-SRS in a patient. Prior WBRT; progressing systemic disease and CNS-penetrating drug option available; and progressing systemic disease and immunotherapy option available were the most common responses. Most respondents cited "specific request by medical oncology" as well as "cooperative studies in this topic" as factors that might push them towards SL-SRS. Several institutions specified factors beyond the listed options. One institution reported that for patients with >20 lesions, they treated the largest lesions with SRS then follow with WBRT, termed the "pre-WBRT boost." Progression of untreated lesions was the most common reason why providers would bring back patients for additional treatment. CONCLUSION The responses to this survey demonstrate that patients with >15-20 intracranial lesions, prior WBRT, and worsening systemic disease with CNS penetrating systemic therapies available are being considered for SL-SRS.

Abstract
INTRODUCTION Academic integrity among radiographers and nuclear medicine technologists/scientists in both higher education and scientific writing has been challenged by advances in artificial intelligence (AI). The recent release of ChatGPT, a chatbot powered by GPT-3.5 capable of producing accurate and human-like responses to questions in real-time, has redefined the boundaries of academic and scientific writing. These boundaries require objective evaluation. METHOD ChatGPT was tested against six subjects across the first three years of the medical radiation science undergraduate course for both exams (n = 6) and written assignment tasks (n = 3). ChatGPT submissions were marked against standardised rubrics and results compared to student cohorts. Submissions were also evaluated by Turnitin for similarity and AI scores. RESULTS ChatGPT powered by GPT-3.5 performed below the average student performance in all written tasks with an increasing disparity as subjects advanced. ChatGPT performed better than the average student in foundation or general subject examinations where shallow responses meet learning outcomes. For discipline specific subjects, ChatGPT lacked the depth, breadth, and currency of insight to provide pass level answers. CONCLUSION ChatGPT simultaneously poses a risk to academic integrity in writing and assessment while affording a tool for enhanced learning environments. These risks and benefits are likely to be restricted to learning outcomes of lower taxonomies. Both risks and benefits are likely to be constrained by higher order taxonomies. IMPLICATIONS FOR PRACTICE ChatGPT powered by GPT3.5 has limited capacity to support student cheating, introduces errors and fabricated information, and is readily identified by software as AI generated. Lack of depth of insight and appropriateness for professional communication also limits capacity as a learning enhancement tool.

Abstract
Past influenza pandemics including the Spanish flu and H1N1 have disproportionately affected Indigenous Peoples. We conducted a systematic scoping review to provide an overview of the state of understanding of the experience of Indigenous peoples during the first 18 months of the COVID-19 pandemic, in doing so we capture the state of knowledge available to governments and decision makers for addressing the needs of Indigenous peoples in these early months of the pandemic. We addressed three questions: (a) How is COVID-19 impacting the health and livelihoods of Indigenous peoples, (b) What system level challenges are Indigenous peoples experiencing, (c) How are Indigenous peoples responding? We searched Web of Science, Scopus, and PubMed databases and UN organization websites for publications about Indigenous peoples and COVID-19. Results were analyzed using descriptive statistics and content analysis. A total of 153 publications were included: 140 peer-reviewed articles and 13 from UN organizations. Editorial/commentaries were the most (43%) frequent type of publication. Analysis identified Indigenous peoples from 19 different countries, although 56% of publications were centered upon those in Brazil, United States, and Canada. The majority (90%) of articles focused upon the general adult population, few (<2%) used a gender lens. A small number of articles documented COVID-19 testing (0.04%), incidence (18%), or mortality (16%). Five themes of system level challenges affecting exposure and livelihoods evolved: ecological, poverty, communication, education and health care services. Responses were formal and informal strategies from governments, Indigenous organizations and communities. A lack of ethnically disaggregated health data and a gender lens are constraining our knowledge, which is clustered around a limited number of Indigenous peoples in mostly high-income countries. Many Indigenous peoples have autonomously implemented their own coping strategies while government responses have been largely reactive and inadequate. To 'build back better' we must address these knowledge gaps.

Abstract
This article provides a stocktake of the adaptation literature between 2013 and 2019 to better understand how adaptation responses affect risk under the particularly challenging conditions of compound climate events. Across 39 countries, 45 response types to compound hazards display anticipatory (9%), reactive (33%), and maladaptive (41%) characteristics, as well as hard (18%) and soft (68%) limits to adaptation. Low income, food insecurity, and access to institutional resources and finance are the most prominent of 23 vulnerabilities observed to negatively affect responses. Risk for food security, health, livelihoods, and economic outputs are commonly associated risks driving responses. Narrow geographical and sectoral foci of the literature highlight important conceptual, sectoral, and geographic areas for future research to better understand the way responses shape risk. When responses are integrated within climate risk assessment and management, there is greater potential to advance the urgency of response and safeguards for the most vulnerable.

Abstract
In this Personal View, we explain the ways that climatic risks affect the transmission, perception, response, and lived experience of COVID-19. First, temperature, wind, and humidity influence the transmission of COVID-19 in ways not fully understood, although non-climatic factors appear more important than climatic factors in explaining disease transmission. Second, climatic extremes coinciding with COVID-19 have affected disease exposure, increased susceptibility of people to COVID-19, compromised emergency responses, and reduced health system resilience to multiple stresses. Third, long-term climate change and prepandemic vulnerabilities have increased COVID-19 risk for some populations (eg, marginalised communities). The ways climate and COVID-19 interact vary considerably between and within populations and regions, and are affected by dynamic and complex interactions with underlying socioeconomic, political, demographic, and cultural conditions. These conditions can lead to vulnerability, resilience, transformation, or collapse of health systems, communities, and livelihoods throughout varying timescales. It is important that COVID-19 response and recovery measures consider climatic risks, particularly in locations that are susceptible to climate extremes, through integrated planning that includes public health, disaster preparedness, emergency management, sustainable development, and humanitarian response.

Abstract
Digital Infrastructure Management-Challenges and Opportunities in Post Covid Era are analyzed in this paper. The 2020 pandemic has been the most serious issue in medical as well as humanity’s history. It has impacted various lives in one way or another. There are multitudes of death cases globally, and the census is pacing at its fastest rate as possible. This lockdown has stressed the medical field and infrastructure and paved its way in the digitalization sector. While observing the lockdown, the world’s economy has faced a steep fall due to sudden and unexpected hampering to the daily work. This opened the door to digitalization. The Digital field has seen a great hike where all the work is shifted from offices to home. It has opened various opportunities but also faces major challenges which expect to furnish after the pandemic crisis. This paper deals with the aspects of digital infrastructure in the post-Covid-19 era.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
The association of amyotrophic lateral sclerosis and pancreatic cancer is rare. Amyotrophic lateral sclerosis is a neurodegenerative disease characterised by pure motor symptoms in the form of progressive muscle weakness and wasting, and can involve the bulbar and respiratory muscles, leading to significant morbidity. Successful surgery for patients with amyotrophic lateral sclerosis for pancreatic cancer has rarely been reported. Surgery in such patients is a dual-edged sword and is decided based on risk-benefit ratio. Patients are at high risk for general anaesthesia because of muscular weakness, increased sensitivity to muscle relaxants and certain anaesthetic drugs. There is a high chance of prolonged postoperative ventilatory support, aspiration pneumonia and pulmonary complications. We report a patient with cancer of the head of the pancreas who underwent successful elective pancreaticoduodenectomy.

Abstract
Background High rates of preterm births remain a UK public health concern. Preterm birth is a major determinant of adverse infant and longer-term outcomes, including survival, quality of life, psychosocial effects on the family and health care costs. We aim to test whether a model of care combining continuity of midwife care with rapid referral to a specialist obstetric clinic throughout pregnancy, intrapartum and the postpartum period is feasible and improves experience and outcomes for women at increased risk of preterm birth. Methods This pilot, hybrid, type 2 randomised controlled implementation trial will recruit 350 pregnant women at increased risk of preterm birth to a midwifery continuity of care intervention or standard care. The intervention will be provided from recruitment (antenatal), labour, birth and the postnatal period, in hospital and community settings and in collaboration with specialist obstetric clinic care, when required. Standard care will be the current maternity care provision by NHS midwives and obstetricians at the study site. Participants will be followed up until 6–8 weeks postpartum. The composite primary outcome is the appropriate initiation of any specified interventions related to the prevention and/or management of preterm labour and birth. Secondary outcomes are related to: recruitment and attrition rates; implementation; acceptability to women, health care professionals and stakeholders; health in pregnancy and other complications; intrapartum outcomes; maternal and neonatal postnatal outcomes; psycho-social health; quality of care; women’s experiences and health economic analysis. The trial has 80% power to detect a 15% increase in the rate of appropriate interventions (40 to 55%). The analysis will be by ‘intention to treat’ analysis. Discussion Little is known about the underlying reasons why and how models of midwifery continuity of care are associated with fewer preterm births, better maternal and infant outcomes and more positive experiences; nor how these models of care can be implemented successfully in the health services. This will be the first study to provide direct evidence regarding the effectiveness, implementation and evaluation of a midwifery continuity of care model and rapid access to specialist obstetric services for women at increased risk of preterm birth. Trial registration ISRCTN37733900. Retrospectively registered on 21 August 2017.

Abstract
BACKGROUND The evidence of hypothalamic-pituitary-adrenal axis dysfunction in schizophrenia has been reviewed in the context of the stress-diathesis model. Overactivation of this axis leads to altered blood levels of cortisol and dehydroepiandrosterone sulfate (DHEA-S). These neurosteroids in turn act on the hippocampus and interact with gamma-aminobutyric acid and N-methyl-D-aspartate receptors leading to neurotoxicity and may be involved in the neurobiology of aggression. This study aimed to explore the blood level of these neurosteroids and ascertain its correlation with state aggression and psychopathology in first-episode antipsychotic-naïve schizophrenic patients. METHODS A total of 30 patients with first-episode schizophrenia along with 20 age- and gender-matched healthy controls participated in the study. Both groups were subjected to serum cortisol and DHEA-S measurement after assessment of psychopathology and aggression on a standardised psychometric scale. RESULTS Serum DHEA-S level was significantly higher in the patient group (p = 0.001). No difference was noted between males and females in the patient group (p = 0.93) but female controls had a significantly lower serum DHEA-S level than male controls (p < 0.01). Serum DHEA-S inversely correlated with scores on Modified Overt Aggression Scale (p = 0.01) but not with Positive and Negative Syndrome Scale (p = 0.39) or Clinical Global Impression Scale (p = 0.28). CONCLUSION The first-episode antipsychotic-naïve schizophrenic patients showed a significantly higher blood level of DHEA-S compared with healthy controls. Serum DHEA-S level has an inverse relationship with aggression and may serve as a biological adaptive mechanism to antagonise the neuronal damage caused by cortisol.

Abstract
BACKGROUND High importance is given to plantar pressure monitoring in the field of biomedical engineering for the diagnosis of posture related ailments associated with diseases such as diabetes and gonarthrosis. OBJECTIVE This paper presents the proof-of-concept development of a new high resolution plantar pressure monitoring pad based on fiber Bragg grating (FBG) sensors. METHODS In the proposed configuration, the FBG sensors are embedded within layers of carbon composite material (CCM) in turn conforming to an arc shape. A total of four such arc shaped sensors are instrumented in the pad at the locations of the forefoot and the hind foot. As a test of the pad, static plantar pressure is monitored on normal subjects under various posture conditions. The pad is evaluated both as a standalone platform as well as a pad inserted inside a standard shoe. RESULTS An average pressure sensitivity of 1.2 pm/kPa and a resolution of approximately 0.8 kPa is obtained in this special configuration. The pad is found to be suitable in both configurations- stand-alone pad as well as an insert inside a standard shoe. CONCLUSION The proposed set up offers a cost-effective high resolution and accurate plantar pressure measurement system suitable for clinical deployment. The novelty of the developed pressure pad lies in its ability to be used both as platform type as well as inserted in-sole type sensor system.

Abstract
BACKGROUND Clinical monitoring of planar pressure is vital in several pathological conditions, such as diabetes, where excess pressure might have serious repercussions on health of the patient, even to the extent of amputation. OBJECTIVE The main objective of this paper is to experimentally evaluate the combined application of the Fibre Bragg Grating (FBG) and the lead zirconate titanate (PZT) piezoceramic sensors for plantar pressure monitoring during walk at low and high speeds. METHODS For fabrication of the pressure sensors, the FBGs are embedded within layers of carbon composite material and stacked in an arc shape. From this embedding technique, average pressure sensitivity of 1.3 pm/kPa and resolution of nearly 0.8 kPa is obtained. These sensors are found to be suitable for measuring the static and the low-speed walk generated foot pressure. Simultaneously, PZT patches of size 10 × 10 × 0.3 mm were used as sensors, utilizing the d<formula>_{33}</formula> (thickness) coupling mode. A sensitivity of 7.06 mV/kPa and a pressure resolution of 0.14 kPa is obtained from these sensors, which are found to be suitable for foot pressure measurement during high speed walking and running. Both types of sensors are attached to the underside of the sole of commercially available shoes. In the experiments, a healthy male subject walks/runs over the treadmill wearing the fabricated shoes at various speeds and the peak pressure is measured using both the sensors. Commercially available low-cost hardware is used for interrogation of the two sensor types. RESULTS The test results clearly show the feasibility of the FBG and the PZT sensors for measurement of plantar pressure. The PZT sensors are more accurate for measurement of pressure during walking at high speeds. The FBG sensors, on the other hand, are found to be suitable for static and quasi-dynamic (slow walking) conditions. Typically, the measured pressure varied from 400 to 600 kPa below the forefoot and 100 to 1000 kPa below the heel as the walking speed varied from 1 kilometer per hour (kmph) to 7 kmph. CONCLUSIONS When instrumented in combination, the two sensors can enable measurements ranging from static to high speed conditions Both the sensor types are rugged, small sized and can be easily embedded in commercial shoes and enable plantar pressure measurement in a cost-effective manner. This research is expected to have application in the treatment of patients suffering from diabetes and gonarthrosis.

Abstract
BACKGROUND Undergoing an endoscopy is a stressful experience for patients. AIMS To audit the endoscopy pathway to improve patient satisfaction. METHODS A prospective survey of endoscopy patients to identify system improvements that were then implemented. RESULTS The survey was performed before (N = 71) and after (N = 60) process improvements identified by the initial survey. Information provision and staff communication skills were identified for optimisation. Patient anxiety at home was significantly reduced (median 2 vs. 1, p < 0.01). Education of endoscopy staff significantly improved the quality of information provided before and after the procedure with regard to sedation (median 4 vs. 5, p < 0.01), discomfort (median 4 vs. 5, p < 0.01), complications (28 vs. 82 %, p < 0.01), findings (89 vs. 100 %, p < 0.01) and follow-up (73 vs. 90 %, p = 0.015). Gloucester Comfort Scores during endoscopy improved (median 1 vs. 0, p < 0.01) without increasing sedation levels. Patient feelings of invasion/trauma significantly decreased. Overall 95 % of patients were satisfied. CONCLUSION Structured information leaflets and improved staff communication skills reduce anxiety and enhance patients' experiences. They are now standard operating procedures.

Abstract
BACKGROUND Despite continued progress towards an elucidation of pathogenetic pathways in vitiligo, a definitive cure remains elusive. Noncultured epidermal cell suspension (NCECS) is emerging as the treatment of choice for surgical management of both stable and segmental vitiligo. NCECS is very effective in repigmenting stable vitiligo, but the technique requires an expert and the support of a laboratory facility. OBJECTIVES To investigate a simplified and more cost-effective method for NCECS. METHODS We simplified the conventional NCECS method and made it more cost-effective and simple enough to be performed in the clinic without laboratory equipment. We named this the four compartment (FC) method. Six patients with vitiligo were treated with this FC method. RESULTS The FC method for NCECS is highly cost-effective and simple. Six patients with vitiligo were treated and the results showed marked to complete repigmentation in four patients and > 50% repigmentation in two patients in 3 months. CONCLUSIONS The FC method is a cost-effective and simple procedure to prepare epidermal cell suspensions. In this modified method we showed that there is no need for pipette, tips, centrifuge tube and most importantly a centrifuge machine or any other expensive laboratory equipment.

Abstract
Uterine arteriovenous malformations are rare lesions which have a varied presentation that may range from the patient being asymptomatic to varying degrees of menorrhagia. It can be diagnosed by Doppler sonography but a strong index of suspicion is necessary. Management of this condition depends on presentation and available resources. In asymptomatic patients, we can leave the patients on regular follow-up as many lesions regress spontaneously. In patients with excessive haemorrhage not responding to embolisation or when facilities of embolisation are not available, hysterectomy needs to be done. Uterine artery embolisation should be considered the optimum treatment, as it has a high success rate coupled with few complications and also has fertility-preserving potential. Clinical follow-up usually suffices but sonography may occasionally be required.

Abstract
Aim: Spectacle wearers often prefer tintedlenses to clear or non-tinted lenses for their protection against harmful radiation, improved cos-mesis, enhancement of visual performance and effects on colour vision. Among the available tinted lenses on the market blue, brown and grey tinted spectacle lenses are popular with varying gradesranging from A to D. Due to reduced transmission of light through such lenses, the optical system of the eyes and the environmental vision may be temporarily altered. Colour vision (CV) and con-trast sensitivity (CS) are important aspects of this altered visual world. This study investigated the effect of spectacle lenses of varying grades of tint on CS and CV.Method: The study adopted a pre- and postest research design and a sample of 90 participants were selected from the University of KwaZulu-Natal student population using convenience sam-ling. Each participant was screened for patholgy, dyschromatopsia, severe dry eyes (TBUT<5 seconds), and the presence of any more than low metropia. Thereafter each successful participant was tested for CS and CV with their habitual precription and then tested randomly with a white clear) lens (placebo) and tinted (blue, brown, and grey) spectacle lenses made of CR39 material each having grades A, B and C over their habitual state. Light transmission was 85%, 75%, and 50% for grades A, B, and C respectively. The Functional Acuity Contrast Test (FACT) chart and American Optical Hardy, Rand, and Rittler (AO HRR) were used for the assessment of CS and CV respectively.Results: The data was analysed using the Statistical Package of Social Science (SPSS) version18. Compared to the habitual state, contrast sensitivity was enhanced with all the tinted lensesThe greater enhancement was for low spatial frequencies (LSF) and least for high spatial frequencies (HSF). With all tints Grade C had the least enhancement for very HSF. Many subjects showed no change in CV with any of the lensesused. The grey tint showed greater enhancement of CV as the density increases. Blue and brown tints showed a similar trend with grade B enhancing CV the most while grade C resulted in theleast reduction of CV.Conclusion: Grade A, B, and C of blue, brown and grey tinted spectacle lenses do not alter colour vision significantly but for the selected levels of transmission of the tints used, contrast sensitivity can be improved to some extent.
