Abstract
GLP-1 receptor agonist treatment revolutionised the management of type 2 diabetes mellitus with significant enhancement of cardiovascular risk reduction. They have been instrumental in effectively managing the glycaemic control of this at-risk patient group. This class of drugs are associated with rapid improvement in glucose levels and consequently, transient early worsening of pre-existing diabetic retinopathy (DR) which is well-recognised, but this paradox is less commonly perceived in routine clinical practice. The recent shortage of supply has resulted in an enforced hiatus to prescribing all existing GLP-1 receptor agonists, which is expected to last all through 2024. This becomes even more pertinent as their DR could have progressed due to worsening HbA1c as a result of the unforeseen interruption to GLP-1 receptor agonist treatment. Therefore, when these medications are recommenced in a few months' time, all prescribers need to be aware of these patients' most up-to-date DR status and liaise with their affiliated screening service.

Abstract
Diabetic retinopathy and nephropathy share pathophysiological mechanisms and there is a defined correlation between the severity of both these microvascular complications from suboptimal glycaemic control. The reno-protective properties offered by sodium-glucose co-transporter-2 inhibitors and glucagon-like peptide-1 receptor agonists should be applicable to diabetic retinopathy as well. However, in patients with pre-existing diabetic retinopathy, sudden improvement in glycaemic control is well documented to cause early worsening of the changes in the retina that is usually transient. This paradoxical phenomenon tends to occur with longer duration of diabetes, higher HbA1c at the outset, rapid improvement of glucose levels and the magnitude of HbA1c reduction with addition of more agents to tighten metabolic control. Interestingly, this progression of pre-existing diabetic retinopathy is not quite observed with newer sodium-glucose co-transporter-2 inhibitors. This article discusses potential further areas of future research where mechanisms of renal protection can be translated to the retina.

Abstract
OBJECTIVE To assess the incidence of referable diabetic retinopathy (DR) in patients aged 80 and 85 years to determine whether screening interval can be extended safely in this age group. METHODS Patients who were aged 80 and 85 years when they attended digital screening during April 2014-March 2015 were included. Screening results at baseline and over the next four years were analysed. RESULTS 1880 patients aged 80 and 1105 patients aged 85 were included. Patients referred to hospital eye service (HES) for DR ranged from 0.7% to 1.4% in the 80-year-old cohort over 5 years. In this cohort a total of 76 (4%) were referred to HES for DR, of which 11 (0.6%) received treatment. Over the course of the follow up (FU), 403 (21%) died. In the 85-year-old cohort, referral to HES for DR each year ranged from 0.1% to 1.3%. In this cohort a total of 27 (2.4%) were referred to HES for DR, of which 4 (0.4%) received treatment. Over the course of follow-up 541(49%) died. All treated cases were for maculopathy in both cohorts and there were no cases of proliferative diabetic retinopathy requiring treatment. CONCLUSION This study showed that the risk of progression of retinopathy is quite low in this age group and only a small proportion of patients developed referable retinopathy requiring treatment. This suggests relooking at the need for screening and ideal screening intervals in patients aged 80 years and over with no referable DR as they can be potentially classed as a group with low risk of sight loss.

Abstract
Nanoparticles (NPs) exhibit remarkable potential in the diagnosis and treatment of various liver ailments, including primary liver cancer or hepatocellular carcinoma (HCC), liver cirrhosis, viral hepatitis, and alcoholic and non-alcoholic liver diseases. High surface area-to-volume ratio with distinct physicochemical and bio-pharmaceutical properties have contributed numerous benefits to NPs, such as high intracellular uptake and efficient drug delivery capabilities stemming from their ability to encapsulate a diverse range of drugs. Lipid-based nanosystems have demonstrated significant potential as reliable and efficient transport vehicles for a variety of actives, including small interfering RNA, targeting the liver, owing to their excellent in vivo compatibility, biodegradable nature, and non-toxic properties. Multiple aspects of various lipid-based materials, lipid nanosystems like solid lipid NPs, nanovesicles such as nanoemulsions, liposomes, and nanomicelles for liver-specific active targeting have been comprehensively reviewed. Ongoing and completed clinical trials of lipid nanosystems developed for HCC, hepatic fibrosis, and hepatitis are tabulated. Types of receptors and ligands typically used for active liver targeting in HCC are extensively discussed. The US FDA's recent approval for the use of Onpattro (Patisiran) injection to treat polyneuropathy in adult patients is indicative of the rapid development of lipid nanosystems employed for hepatic targeting. Nanoemulsions loaded with diagnostic imaging agents for multi-modal liver imaging were briefly discussed. Emerging technologies are being developed to integrate desirable properties of nanoparticles (NPs), including high stability, efficient drug loading, opsonization avoidance, active liver targeting, and facilitation of endosomal escape. Clinical translations of many lipid NPs for drug and gene therapy applications targeting different liver diseases are expected in the near future.

Abstract
Oxytocin has been used to treat neurodevelopmental conditions in adolescent patients but possible effects on reproductive development have not been well investigated. The effects of daily intra-nasal oxytocin treatment (12-18 months of age) on puberty and fertility were studied in colony-housed, male and female titi monkeys (Plecturocebus cupreus). Body weight, urinary conjugated pregnanes and estrogens (defining cyclicity) in females, and androgens and sperm in urine of in males, were measured from 1 to 3 years of age to detect puberty. Serum testosterone was also measured in males at 13, 23 and 33 months of age and hemi-castration at 3 years of age enabled assessment of testicular morphometry and oxytocin receptor expression. An oxytocin treatment*time interaction suggested a minor, transient suppression in weight gain after treatment ended. Note that females weighed 10% less across all ages. Oxytocin-treated females exhibited early, spurious ovulations but neither regular cyclicity (≈30 months) nor pregnancies were affected by treatment. Oxytocin did not affect the pubertal increase in urinary androgen or the first appearance of sperm, which occurred as early as 15 months of age. Treatment did delay the puberty-associated rise in serum testosterone in males. All males were pubertal by 22 months and all females by 32 months of age. Although no major male or female fertility outcome was observed, oxytocin demonstrated some physiological effects through a delay of testosterone secretion in males, induction of precocious ovulation in females, and a suppression of general weight gain for the months following treatment.

Abstract
Background Among cardiac complications of breast cancer radiotherapy (BC RT), there are very limited data on arrhythmia and conduction disorders, in particular severe cases requiring permanent pacemaker implantation (PPMI). Therefore, this exploratory study aimed to evaluate the risk of PPMI for BC patients treated with RT, compared with the general population and with BC patients not treated with RT. Methods The study was performed on a 1/97 representative sample of the French health care database (EGB database). Adult women with a first BC treated with or without RT between 2008 and 2016 were included, followed until 2018, and de novo PPMI were identified. We compared the PPMI incidence in BC cohort relative to the general population with standardized incidence ratio (SIR) and evaluated the risk of PPMI in RT patients compared to patients without RT with a competing risk survival analysis. Results A total of 3853 BCE patients were included. Among BC patients treated with RT, 28 PPMI cases were observed compared with 13 expected cases, corresponding to a SIR of 2.18 [95% CI: 1.45-3.06]. For BC patients not treated with RT, the SIR was 1.01 [95% CI: 0.40-1.90]. Patients treated with RT showed a borderline significant higher risk of PPMI compared with those not treated with RT (subdistribution Hazard Ratio = 2.08, 95% CI 0.87-4.97, p = 0.09). Conclusions Our exploratory findings indicate that, over the last decade in France, BC patients treated with RT appeared to be at higher risk of PPMI than general population. Further studies are needed to expand on this topic.

Abstract
Abstract
Background
Radiotherapy (RT) is a major treatment for breast cancer (BC), but it is also associated with an increased long-term (>5–10 years) risk of cardiac complications. Specific data on cardiac arrhythmias and conduction disorders are warranted.
Purpose
To evaluate whether pacemaker (PM) implantation risk is higher in BC patients treated with RT compared to the general population or population of BC patients treated without RT.
Methods
Our study was based on the Echantillon Généraliste de Bénéficiaires (EGB), the 1/97 random sample of the French nationwide health insurance claims database. The population of patients treated for BC consisted of adult women with a first BC identified by the ICD-10 diagnosis codes between 2008 and 2016, and followed through 2018. PM implantations and RT were identified with medical procedures codes in the french Common Classification of Medical Procedures (CCAM). For each year from 2008 to 2018, the reference population included all adult women of the EGB database. History of PM or BC was an exclusion criteria. Annual incidence rates of PM implantations were evaluated between 2008 and 2018 in the reference populations. The number of PM cases observed in BC patients at least one year after BC diagnosis was compared with the expected number of PM cases calculated by using reference incidence rates with age standardization. We then computed the standardized incidence ratio (SIR) as the ratio of the observed number of PM to the expected number of PM, with 95% confidence intervals (CIs). Thereafter, a survival analysis was performed in BC patients using a Cox regression model (Hazard Ratio – HR) in order to evaluate the risk of PM associated with treatment including RT (RT) compared with treatment not including RT (no RT).
Results
A total of 3,853 patients were included in the population of patients treated for BC between 2008 and 2016 with a mean age of 60 years old and a mean follow-up of 5.6 years. In this population, 35 cases of PM were observed, compared with 19.9 expected cases of PM, corresponding to a significant SIR=1.76 (95% CI: 1.22 - 2.39). This excess risk was carried by the RT group of 2973 patients (77% of BC population): 28 observed PM vs 12.9 expected, SIR=2.18 (95% CI: 1.45–3.06). In Cox regression analysis, after adjustment on age, RT was associated with an increased risk of PM compared with no RT, but this result did not reach statistical significance (HR=1.73; p-value=0.21).
Conclusion
Based on our study, BC patients receiving RT appeared to be at higher risk of PM implantation than general female population and BC patients without RT, illustrating a potential association between cardiac exposure during BC RT and conduction disorders.

Abstract
Abstract
Background
The indications for permanent pacemaker implantation (PPMI) are strongly associated with age, with the highest rates for octogenarians (>80 years old). Over the last decade, impact of aging on temporal trends in PPMI rates among octogenarians is questionable. In the 2010's, transcatheter aortic valve implantation (TAVI) has emerged for inoperable or high-risk patients, mainly octogenarians, with an exponential increase over years. PPMI is a common short-term complication after TAVI procedure. Many studies have explored these post-TAVI PPMI in terms of incidence, timing and outcomes of PPMI following TAVI, but there are no data on the impact of TAVI on PPMI temporal trend at a nationwide scale.
Purpose
To evaluate whether PPMI in octogenarians have increased during the last decade, independently from age and sex, on a nationwide scale. Eventually, to estimate the potential contribution of TAVI in PPMI increase in this setting.
Methods
Our study was based on octogenarians from the Echantillon Généraliste de Bénéficiaires, the 1/97 random sample of the French nationwide health insurance claims database. Between 2008 and 2018, we identified de novo PPMI and TAVI with medical procedures codes in the French Common Classification of Medical Procedures (CCAM). Annual incidence rates of PPMI were evaluated between 2008 and 2012 (preTAVI-period). The number of observed PPMI cases, O, in the period 2013–2018 (TAVI-period) was compared with the expected number of PPMI cases, E, calculated by using 2008–2012 incidence rates with age and sex standardization. We then computed the standardized incidence ratio (SIR) of the observed number of PPMI to the expected number of PPMI (O/E), with 95% confidence intervals (CIs). Thereafter, we evaluated the contribution of post-TAVI PPMI in the number of excess cases of PPMI (O-E) for the period 2013–2018.
Results
The population of octogenarians increased from 23,822 in 2008 to 33,752 in 2018. In 2008, 130 PPMI were observed (546/100,000 inhabitants) reaching 228 PPMI (676/100,000) in 2018 with a marked increase in rates from the year 2012. During the period 2013–2018, for all octogenarians, 1242 cases of PPMI were observed, compared with 1171.3 expected cases of PPMI, corresponding to a significant SIR=1.06 (95% CI: 1.01–1.12). For the subpopulation of octogenarians without TAVI, no excess risk was observed with a SIR=1.01 (95% CI: 0.95–1.06). Among the excess cases of PPMI observed in 2013–2018 in all octogenarians, 72% were post-TAVI PPMI.
Conclusion
Based on our study, the number of observed PPMI in octogenarians in period 2013–2018 is 6% higher than the number we would expect. Nearly three-quarter of these excess cases are attributable to TAVI complication.

Abstract
Juvenile crime or delinquency has been increasing at an alarming rate in recent times. In many countries, including India, the minimum age for criminal responsibility is 16 years. The present study aimed to estimate the probability of a south Indian adolescent either being or being older than the legally relevant age of 16 years using Demirjian's tooth formation stages. Orthopantomograms (OPG) of 640 south Indian adolescents (320 boys and 320 girls) aged between 12 and 20 years were retrospectively analyzed. In each OPG, Demirjian's formation stage of the mandibular left third molar was recorded and the data was subjected to statistical analysis. Descriptive and Pearsons correlation statistics were performed. The empirical probabilities were provided relative to the medico-legal question of predicting 16 years of age. The distribution of age throughout the 10th, 25th, 50th, 75th and 90th percentile follows a logical distribution pattern horizontally and vertically. Pearson's correlation statistics showed a strong positive correlation between the Demirjian's stages and age for both sexes. Therefore, it can be concluded that stage "F" can be used to predict the attainment of age equal to or older than 16 years with a probability of 93.9% for boys and 96.6% for girls.

Abstract
BACKGROUND It is recognized that healthcare workers (HCWs) are at high risk of contracting Covid-19. It is incumbent on occupational health staff to recognize potential symptoms of Covid-19 among HCWs. AIMS The aims of the study were to describe the presenting symptoms of HCWs who developed Covid-19 in Ireland, and to estimate the odds of specific symptoms being associated with a positive Covid-19 polymerase chain reaction (PCR) result. METHODS A retrospective chart review of all symptomatic HCWs who self-presented for Covid-19 testing in Cork from March to May 2020 was conducted. A sex-matched case-control study was carried out to compare presenting features among those who tested positive compared to those who tested negative. Univariate and multivariable-adjusted conditional logistic regression models were run using Stata 15.0 to identify the symptoms associated with positive Covid-19 swab results. RESULTS Three hundred and six HCWs were included in the study; 102 cases and 204 controls. Common presenting features among cases were fever/chills (55%), cough (44%) and headache (35%). The symptoms which were significantly associated with a positive Covid-19 swab result were loss of taste/smell (adjusted odds ratio [aOR] 12.15, 95% confidence interval [CI] 1.36-108.79), myalgia (aOR 2.36, 95% 1.27-4.38), fatigue (aOR 2.31, 95% CI 1.12-4.74), headache (aOR 2.11, 95% CI 1.19-3.74) and fever/chills (aOR 1.88, 95% CI 1.12-3.15). CONCLUSIONS Fever, fatigue, myalgia, loss of taste/smell and headache were associated with increased odds of a Covid-19 diagnosis among symptomatic self-referred HCWs compared with those had negative swab results. Testing criteria for HCWs should reflect the broad range of possible symptoms of Covid-19.

Abstract
AIMS Compare and characterize Chaetomium strains with special regard to their potentialities as biocontrol agents. METHODS AND RESULTS Twelve strains of the fungal genus Chaetomium from diverse ecological niches were identified as belonging to six different species. Large differences were observed between the strains with regard to temperature requirements for mycelial growth and pigmentation of culture filtrates. Culture filtrates and ethyl acetate extracts were assayed for fungicidal effects against important phytopathogens both on agar media and in multiwell plates. The samples from Chaetomium globosum were particularly active against Botrytis cinerea, Pyrenophora graminea and Bipolaris sorokiniana, while those from C. cochliodes and C. aureum were inhibitory towards Phytophthora infestans, and P. infestans and Fusarium culmorum respectively. To narrow down the active principle, the most promising extracts were separated by preparative HPLC and the resulting fractions tested in bioassays. Chaetoglobosins were identified as active compounds produced by C. globosum. CONCLUSIONS The bioassays revealed C. aureum and C. cochliodes as promising candidates for use in biocontrol. Both showed remarkably good activity against the prominent plant pathogen P. infestans. SIGNIFICANCE AND IMPACT OF THE STUDY We provide the first systematic study comparing six different Chaetomium species with regard to their use as biocontrol agents.

Abstract
AIM To describe the neuroradiological changes in patients with coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS A retrospective review was undertaken of 3,403 patients who were confirmed positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and admitted to Queen Elizabeth Hospital Birmingham, University Hospitals Birmingham NHS Foundation Trust, Birmingham, UK between 1 March 2020 and 31 May 2020, and who underwent neuroimaging. Abnormal brain imaging was evaluated in detail and various imaging patterns on magnetic resonance imaging MRI were identified. RESULTS Of the 3,403 patients with COVID-19, 167 (4.9%) had neurological signs or symptoms warranting neuroimaging. The most common indications were delirium (44/167, 26%), focal neurology (37/167, 22%), and altered consciousness (34/167, 20%). Neuroimaging showed abnormalities in 23% of patients, with MRI being abnormal in 20 patients and computed tomography (CT) in 18 patients. The most consistent neuroradiological finding was microhaemorrhage with a predilection for the splenium of the corpus callosum (12/20, 60%) followed by acute or subacute infarct (5/20, 25%), watershed white matter hyperintensities (4/20, 20%), and susceptibility changes on susceptibility-weighted imaging (SWI) in the superficial veins (3/20, 15%), acute haemorrhagic necrotising encephalopathy (2/20, 10%), large parenchymal haemorrhage (2/20, 10%), subarachnoid haemorrhage (1/20, 5%), hypoxic–ischaemic changes (1/20, 5%), and acute disseminated encephalomyelitis (ADEM)-like changes (1/20, 5%). CONCLUSION Various imaging patterns on MRI were observed including acute haemorrhagic necrotising encephalopathy, white matter hyperintensities, hypoxic-ischaemic changes, ADEM-like changes, and stroke. Microhaemorrhages were the most common findings. Prolonged hypoxaemia, consumption coagulopathy, and endothelial disruption are the likely pathological drivers and reflect disease severity in this patient cohort.

Abstract
Abstract
Background
Medical workers are the largest group of workers occupationally exposed to low doses of ionizing radiation (IR) worldwide.
Aims
This review presents all the cohorts of medical workers exposed in the world and summarizes cancer risks associated with radiation exposure in this population.
Methods
Epidemiological studies on health professionals exposed to IR published from 1975 to 2019 were reviewed. Strength of evidence was assessed according to the modified Royal College of General Practitioners three-star system.
Results
Among the 16 epidemiological studies focusing on cancers from 11 cohorts among medical staff exposed to radiation, higher risks of cancer were observed for pre-1950 exposure and for medical workers who performed fluoroscopically guided interventional procedures or radionuclides procedures compared to those who did not. However, strength of evidence supporting the associations remains moderate as several methodological limits including the lack of dosimetry data, lifestyle factors and recent updates may obscure the link between medical occupational exposure and cancer occurrence.
Conclusions
Excess risk of cancer is suspected for high and former exposures. The more highly exposed professions, i.e. interventional physicians and nuclear medicine workers, should be monitored carefully. Collaborative projects aiming to increase the quantity and quality of information of the studied populations would be a key point

Abstract
The aim of the study was to evaluate the effectiveness of seagull-shaped nasolabial flap (NLF) along with adjunctive short-term oral pentoxifylline in the surgical reconstruction of oral sub mucous fibrosis (OSMF) following fibrotomy. We retrospectively evaluated 18 patients with grade IV oral sub mucous fibrosis treated by NLF. There were 3 females and 15 males. All patients were classified as stage IV OSMF with a mean preoperative mouth opening of 8.11±3.38mm. Postoperatively, patients were administered 400mg of pentoxifylline (PTX) thrice daily for 3 months. Patients were followed up at one month, six months and one year. Mouth opening, presence or absence of malignant transformation, relapse and complications were recorded at each follow-up. We found statistically significant increase in mouth opening from 8.11±3.3 to 37.67±3.74 in the postoperative period. The complications associated with NLF were very minimal. The PTX was well tolerated by all the patients. There was no incidence of relapse or rebound fibrosis seen in our series. To the best of our knowledge, this is the first time that oral pentoxifylline has been administered along with surgical treatment of oral submucous fibrosis to prevent relapse. The use of oral PTX as an adjunct along with surgical reconstruction in OSMF improves mouth opening, reduces burning sensation and relapse.

Abstract
We report a case of cerebral phaeohyphomycosis, a fungal brain infection due to a dark (dematiaceous) fungi in a 6-year-old French Guyanese boy. The child presented fever and drowsiness due to several paraventricular brain abscesses. Neurological surgeries were performed to reduce intracranial hypertension and to obtain abscess biopsies. Mycological cultures of intraoperative samples led to the diagnosis of cerebral phaeohyphomycosis due to Cladophialophora bantiana. The patient neurological status deteriorated and remained critical after several weeks of combination antifungal therapy with voriconazole 8mg/kg/day, liposomal amphotericin B 10mg/kg/day and flucytosine 200mg/kg/day. A complete surgical resection was not possible because of multiple small abscesses. A multidisciplinary ethical staff decided on home medical care with palliative ventriculoperitoneal shunt, nasogastric feeding and analgesics. One year later, the patient's neurological condition had improved and cerebral lesions had regressed, while he had not received any antifungal treatment but only traditional medicines. Cerebral phaeohyphomycosis are rare diseases affecting immunocompromised but also apparently non-immunocompromised patients, as in this case. A complete surgical resection is not always possible and mortality rates are high in spite of treatments with a combination of antifungals. The diagnosis may be difficult because of these dematiaceous fungi's slowly growing and their potential pathogenicity for laboratory staff.

Abstract
BACKGROUND Whiplash associated disorder (WAD), a common and disabling condition, incurs huge burden and costs to Australia. Yet, current treatments for whiplash are not very effective; improved outcomes are urgently needed. Clinical guidelines recommend simple analgesia (paracetamol and non-steroidal anti-inflammatory drugs) but there have been no trials of guideline-recommended drugs. This study will investigate the effectiveness of evidence-based advice (EBA), paracetamol, naproxen, and both paracetamol and naproxen, in reducing daily neck pain and preventing chronic neck pain after whiplash injury. METHODS This study is a pilot series of multi-cycle, double-blinded, randomised N-of-1 trials, nested in a multiple baseline design. The design will comprise three baselines of 5, 8 or 11 days duration. Post enrolment, participants will be randomly assigned to one of the baselines. Fifteen participants with acute (<2 weeks) Grade II WAD, experiencing at least moderate pain (NRS: ≥ 5/10), and at risk of poor recovery will be recruited from hospitals in Queensland, Australia, and through local physiotherapists. Patients will receive EBA plus a randomised sequence of three cycles of ten day treatment triplets (paracetamol designated as a C phase, naproxen, designated as a D phase, and both paracetamol and naproxen, designated as an E phase). DISCUSSION We will test the effects of different treatments on the primary outcome of average neck pain intensity collected daily and at 4 and 7 months post-injury. Secondary outcomes, including disability, depression, post-traumatic stress symptoms, pain catastrophizing, and feasibility of study procedures, will also be evaluated. The results of this study will inform a larger trial aiming to strengthen the evidence on EBA and simple analgesics for WAD. TRIAL REGISTRATION Clinical Trials Primary Registry: Australian and New Zealand Clinical Trials Registry. CLINICAL TRIAL REGISTRATION NUMBER ACTRN12618001291279. DATE OF REGISTRATION 31/07/2018. PRIMARY TRIAL SPONSOR The University of Queensland, Brisbane QLD 4072 Australia. FUNDING The University of Queensland.

Abstract
AIM To assess the effect of pneumatic (air) and fluidic (transport medium) injection to the type of bubble (I, II or mixed III) and the resultant dissection of corneal endothelial grafts PDEK or DMEK. MATERIALS AND METHODS All grafts were obtained from Dr Agrawal Hospital's Eye Bank. Air injection was the initial preferred mode of graft harvest. If pneumatic dissection was unsuccessful after 10 tries, fluidic dissection with transport medium was tried. SPSS 23.0 was used to statistically analyse the data. RESULTS 40 consecutive donor corneas with a mean age of 46.5 and a mean endothelial count of 2980 were analysed. Air dissection lead to the harvest of 27 endothelial grafts and fluid dissection led to the creation of 7 endothelial grafts. Statistically significant difference was found the different bubble types and the type of injection (χ2 chi square=10.02, 0=0.008). CONCLUSION In young donors pneumatic (air) graft dissection leads to PDEK in a high proportion. This percentage is reduced when transport medium is tried after unsuccessful air injection. Injection of transport medium increases the percentage of grafts harvested but also increases the ratio of Type II and III DMEK grafts created.

Abstract
A 34-year-old female soldier presented with fever and behavioural changes while deployed in Kenya and was diagnosed with encephalitis. The patient underwent urgent aeromedical evacuation to the Queen Elizabeth Hospital, Birmingham for further management. Microbiology tests excluded common infectious causes that are endemic in the East Africa region. However, an autoantibody screen was positive for antibodies against the N-methyl-D-aspartate receptor (NMDAR). Full body imaging confirmed the presence of limbic encephalitis and an ovarian mass suggestive of a teratoma. The patient was diagnosed with ovarian teratoma-associated anti-NMDAR encephalitis, a potentially fatal disease. The patient underwent surgery to remove the teratoma and commenced immunotherapy with steroids, plasma exchange and rituximab. This case highlights the diagnostic challenges of fever with behavioural changes in military personnel deployed in a tropical environment.
