RESUMEN
Cutaneous larva migrans (CLM) is one of numerous skin diseases that occur in British military personnel on deployments to the tropics and sub-tropics. It is typically managed by military primary healthcare services, but diagnostic uncertainty or unavailability of anti-helminthic medication may prompt referral to UK Role 4 healthcare services. Cases of CLM seen at the UK Role 4 Military Infectious Diseases & Tropical Medicine Service from 2005 to 2020 were identified and their case notes were reviewed to identify learning and discussion points. There were 12 cases identified, of which five came from Brunei and three were from Belize. Causes for referral were due to diagnostic uncertainty (58%) and the unavailability of anti-helminthic medication (42%). Several cases had CLM in an unusual distribution due to specific military activities performed in endemic areas. Telemedicine was very useful in making some of the diagnoses in theatre and avoiding the need for medical evacuation. Military personnel may have unusual presentations of CLM due their unique military activities. In areas that are endemic for CLM, clinicians should maintain high clinical suspicion for CLM, carry appropriate anti-helminthic medications and consider screening cases of CLM and their colleagues for other infections with similar aetiology (eg, human hookworm infection and strongyloidiasis).

Undifferentiated febrile illnesses present diagnostic and treatment challenges in the Firm Base, let alone in the deployed austere environment. We report a series of 14 cases from Operation TRENTON in South Sudan in 2017 that coincided with the rainy season, increased insect numbers and a Relief in Place. The majority of patients had headaches, myalgia, arthralgia and back pain, as well as leucopenia and thrombocytopenia. No diagnoses could be made in theatre, despite a sophisticated deployed laboratory being available, and further testing in the UK, including next-generation sequencing, was unable to establish an aetiology. Such illnesses are very likely to present in tropical environments, where increasing numbers of military personnel are being deployed, and clinicians must be aware of the non-specific presentation and treatment, as well as the availability of Military Infection Reachback services to assist in the management of these cases.

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.

BACKGROUND: Limited data exist describing supportive care management, laboratory abnormalities and outcomes in patients with Ebola virus disease (EVD) in West Africa. We report data which constitute the first description of the provision of enhanced EVD case management protocols in a West African setting. METHODS: Demographic, clinical and laboratory data were collected by retrospective review of clinical and laboratory records of patients with confirmed EVD admitted between 5 November 2014 and 30 June 2015. RESULTS: A total of 44 EVD patients were admitted (median age 37 years (range 17-63), 32/44 healthcare workers), and excluding those evacuated, the case fatality rate was 49% (95% CI 33%-65%). No pregnant women were admitted. At admission 9/44 had stage 1 disease (fever and constitutional symptoms only), 12/44 had stage 2 disease (presence of diarrhoea and/or vomiting) and 23/44 had stage 3 disease (presence of diarrhoea and/or vomiting with organ failure), with case fatality rates of 11% (95% CI 1%-58%), 27% (95% CI 6%-61%), and 70% (95% CI 47%-87%) respectively (p = 0.009). Haemorrhage occurred in 17/41 (41%) patients. The majority (21/40) of patients had hypokalaemia with hyperkalaemia occurring in 12/40 patients. Acute kidney injury (AKI) occurred in 20/40 patients, with 14/20 (70%, 95% CI 46%-88%) dying, compared to 5/20 (25%, 95% CI 9%-49%) dying who did not have AKI (p = 0.01). Ebola virus (EBOV) PCR cycle threshold value at baseline was mean 20.3 (SD 4.3) in fatal cases and 24.8 (SD 5.5) in survivors (p = 0.007). Mean national early warning score (NEWS) at admission was 5.5 (SD 4.4) in fatal cases and 3.0 (SD 1.9) in survivors (p = 0.02). Central venous catheters were placed in 37/41 patients and intravenous fluid administered to 40/41 patients (median duration of 5 days). Faecal management systems were inserted in 21/41 patients, urinary catheters placed in 27/41 and blood component therapy administered to 20/41 patients. CONCLUSIONS: EVD is commonly associated life-threatening electrolyte imbalance and organ dysfunction. We believe that the enhanced levels of protocolized care, scale and range of medical interventions we report, offer a blueprint for the future management of EVD in resource-limited settings.

INTRODUCTION: Infectious diseases are a frequent cause of morbidity among British troops. The aim of this paper is to describe the spectrum of infectious diseases seen when UK service personnel are evacuated for definitive care to the Role 4 Medical Treatment Facility based at Birmingham Heartlands Hospital. METHOD: A retrospective analysis of all military patients presenting with infectious diseases and treated at Birmingham Heartlands Hospital between 14 April 2005 and 31 December 2013 was undertaken. RESULTS: During this period, 502 patients were identified. Infections originated in 49 countries, most commonly Afghanistan (46% cases), the UK (10% cases) and Belize (9% of cases). The most common presentations were dermatological conditions, gastroenterological illnesses and undifferentiated fevers. CONCLUSION: UK service personnel in significant numbers continue to suffer a wide range of infectious diseases, acquired throughout the globe, which often require specialist tertiary infection services to diagnose and manage. Future prospective data collection is recommended to identify trends, which in turn will inform military training needs and future research priorities in the Defence Medical Services (DMS) and allows development of appropriate policies and clinical guidelines for management of DMS personnel with infectious diseases.

Cutaneous myiasis is a well-described problem in travellers to endemic regions including military personnel. Realistic training is important to ensure that healthcare workers have the confidence and expertise to recognise cutaneous myiasis and safely remove larvae if required. A model is described here that is simple, reproducible and realistic, and will allow for training of military healthcare workers in safe surgical removal of larvae when required.

Multiplex PCR can provide rapid diagnosis for patients presenting with an acute undifferentiated febrile illness. Such technology is useful in deployed settings, where access to conventional microbiological diagnosis is limited. It was used in Sierra Leone to guide management of febrile healthcare workers, in whom Ebola virus disease was a possible cause. In particular, it informed appropriate antibiotic treatment while minimising the risk to clinicians of exposure to the causative organism.

Undifferentiated febrile illness in a returning soldier is a common problem encountered by serving medical officers. A 32-year-old soldier presented to Birmingham Heartlands Hospital with fever and acute kidney injury after return from Borneo. Leptospirosis was suspected and empirical antibiotics were started before subsequent confirmation by serology and PCR. Leptospirosis is common in South-East Asia, and troops exercising in jungle areas, and in the UK, are at risk. Advice, including inpatient management when appropriate, is available from the UK Role 4 Military Infectious Diseases and Tropical Medicine Service.

Enteric fever (typhoid and paratyphoid) remains a threat to British troops overseas and causes significant morbidity and mortality. We report the case of a soldier who developed typhoid despite appropriate vaccination and field hygiene measures, which began 23â days after returning from a deployment in Sierra Leone. The incubation period was longer than average, symptoms started 2â days after stopping doxycycline for malaria chemoprophylaxis and initial blood cultures were negative. The Salmonella enterica serovar Typhi eventually isolated was resistant to amoxicillin, co-amoxiclav, co-trimoxazole and nalidixic acid and had reduced susceptibility to ciprofloxacin. He was successfully treated with ceftriaxone followed by azithromycin, but 1â month later he remained fatigued and unable to work. The clinical and laboratory features of enteric fever are non-specific and the diagnosis should be considered in troops returning from an endemic area with a febrile illness. Multiple blood cultures and referral to a specialist unit may be required.

In October 2014 the UK military deployed to Sierra Leone to provide care for healthcare workers affected by Ebola virus disease. A training package designed by the Army Medical Services Training Centre prepared the deploying personnel in the required infection prevention and control measures. The training used ultraviolet tracer to provide validation of the skills required when treating patients with Ebola and to confirm subsequent decontamination. This training construct provided useful feedback to clinicians on their infection control measures and would be useful in the context of any infection spread by droplets and fomites.

PURPOSE: Early central venous catheter (CVC) insertion in Ebola virus disease (EVD) is a novel approach and has not previously been described. This report delineates the safety, feasibility and clinical implications of early CVC insertion as the optimum means of vascular access in patients with EVD, in the setting of a deployed military Ebola virus disease treatment unit in Sierra Leone. METHODS: In the gastrointestinal phase of EVD, a 7-French 20-cm triple-lumen CVC was inserted using aseptic technique. Data were collected prospectively on all cases to include baseline and subsequent blood test variables, insertion site and technique, and complications associated with CVC placement. RESULTS: Twenty-three patients underwent CVC insertion as follows: subclavian, 21 (88 %); internal jugular, 2 (8 %); axillary, 1 (4 %). The mean duration of CVC placement was 5 days. There were no significant procedure-related adverse events. Despite coagulopathy being present in 75 % of cases, CVC insertion was safe, and there was only 1 case of significant catheter site bleeding. A total of 152 needle venepunctures were avoided owing to the presence of a CVC, a mean of 7 (±3.8) per case over the average stay. CONCLUSION: The early use of CVCs in Ebola virus disease is safe, effective and facilitates patient care. It should be considered a feasible additional route of venous access, where physician expertise and resources allow.

Leishmaniasis is an infectious disease caused by Leishmania protozoa, transmitted by the bite of phlebotomine sandflies. It causes a spectrum of clinical syndromes, of which the most common are cutaneous and visceral leishmaniasis. Clinical presentation is highly variable and is dependent on multiple factors, such as Leishmania species and patient characteristics (including immune competence). The relationship between these variables is poorly understood, and there is no single, evidence-based treatment for the disease. Currently management focuses on identification of the species, but this requires specialist tests which are often unavailable, particularly on military operations. Leishmaniasis is of particular relevance to military medical personnel as it is endemic in many tropical and sub-tropical regions of the world, including Belize, Iraq and Afghanistan where UK Armed Forces may be deployed. It can present a potentially serious threat to military personnel deployed in endemic areas due to the possibility of long-term sequelae of infection.

NATO describes 'Role 4' military medical services as those provided for the definitive care of patients who cannot be treated within a theatre of operations and these are usually located in a military force's country of origin and may include the involvement of civilian medical services. The UK Defence Medical Services have a proud history of developing and providing clinical services in infectious diseases and tropical medicine, sexual health and HIV medicine, and medical microbiology and virology. These UK Role 4 Military Infection Services have adapted well to recent overseas deployments, but new challenges will arise due to current military cutbacks and a greater diversity of contingency operations in the future. Further evidence-based development of these services will require leadership by military clinicians and improved communication and support for 'reach-back' services.

Hepatitis A virus (HAV) and hepatitis E virus (HEV) infections are endemic in most developing countries, including Nepal and Afghanistan, and may cause outbreaks in military personnel. Previously, more than 99% of new British Gurkha recruits were already immune to HAV because of prior infection, but this may be declining due to improved living conditions in their countries of origin. Acute HAV infections have occurred in Gurkha soldiers serving in Afghanistan, which made them unfit for duty for 2-3 months. In one case, early serological diagnosis was impeded by IgM results against both HAV and HEV that were caused by cross-reactivity or persistence from a previous infection. These cases have led to a policy change whereby all Gurkha recruits are now tested for previous HAV infection and if negative they are offered vaccination. Meanwhile, HEV infection remains a significant threat in Nepal and Afghanistan with low levels of background immunity and no commercially available vaccine.

We report a case of successful surgical treatment of Q fever endocarditis with mitral valve repair in a 66-year old retired British soldier. Valve replacement is invariably undertaken in Q fever endocarditis due to the degree of valvular damage and concerns about eradicating the organism, Coxiella burnetii. Our unique case allowed valve repair since pre-existing myxomatous degeneration and subsequent posterior mitral valve leaflet prolapse resulted in significant excess valve tissue, allowing quadrangular resection of the damaged and perforated P2 portion of this leaflet. Follow-up at four years (including three years of antibiotic treatment) has confirmed excellent valve repair, with no echocardiographic, clinical or microbiological evidence of recurrence. We are only the second group to describe valve repair in a patient with chronic Q fever endocarditis. Valve repair is preferable to valve replacement for Q fever endocarditis, if technically possible.

Leishmaniasis is an infectious disease caused by Leishmania protozoa and occurs as a spectrum of clinical syndromes ranging from various forms of cutaneous leishmaniasis (CL) to mucosal leishmaniasis (ML) and visceral leishmaniasis (VL). CL in Afghanistan is either zoonotic (ZCL) due to L. major or anthroponotic (ACL) due to L. tropica and there has been a prolonged epidemic of ACL in eastern Afghanistan since 1987. However, there have been remarkably few reports of CL due to L. tropica amongst foreign troops serving in Afghanistan since 2001. We describe two such cases in Royal Marines deployed to Oruzgan Province in Afghanistan from 2008-9. These patients illustrate important issues regarding the clinical features, referral, diagnosis, treatment and epidemiology of CL amongst foreign troops in Afghanistan. This disease has the potential to cause significant disruption to military personnel and units and so requires efficient management in order to maintain operational effectiveness.
