Dynamic contrast-enhanced near-infrared spectroscopy using indocyanine green on moderate and severe traumatic brain injury: a prospective observational study.
No full textBackground
The care given to moderate and severe traumatic brain injury (TBI) patients may be hampered by the inability to tailor their treatments according to their neurological status. Contrast-enhanced near-infrared spectroscopy (NIRS) with indocyanine green (ICG) could be a suitable neuromonitoring tool.
Methods
Monitoring the effective attenuation coefficients (EAC), we compared the ICG kinetics between five TBI and five extracranial trauma patients, following a venous-injection of 5 mL of 1 mg/mL ICG, using two commercially available NIRS devices.
Results
A significantly slower passage of the dye through the brain of the TBI group was observed in two parameters related to the first ICG inflow into the brain (P=0.04; P=0.01). This is likely related to the reduction of cerebral perfusion following TBI. Significant changes in ICG optical properties minutes after injection (P=0.04) were registered. The acquisition of valid optical data in a clinical environment was challenging.
Conclusions
Future research should analyze abnormalities in the ICG kinetic following brain trauma, test how these values can enhance care in TBI, and adapt the current optical devices to clinical settings. Also, studies on the pattern in changes of ICG optical properties after venous injection can improve the accuracy of the values detected
COVID-19-related intracranial imaging findings: a large single-centre experience.
No full textAIM
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

Complex Enterally Tube-Fed Community Patients Display Stable Tolerance, Improved Compliance and Better Achieve Energy and Protein Targets with a High-Energy, High-Protein Peptide-Based Enteral Tube Feed: Results from a Multi-Centre Pilot Study.
No full textThis pilot study evaluated a high-energy, high-protein, peptide-based, (medium-chain triglycerides) MCT-containing enteral tube feed (Nutrison Peptisorb Plus HEHP, Nutricia Ltd., Trowbridge, BA14 0XQ, UK.) containing 1.5 kcal/mL and 7.5 g protein/100 mL. Fifteen community-based, enterally tube-fed adults (42 (SD 16.3) years) received the intervention feed daily for 28 days, with gastrointestinal tolerance, compliance and nutrient intake assessed at baseline and after the intervention period. Incidence and intensity of constipation ( = 0.496), nausea ( = 1.000), abdominal pain ( = 0.366) and bloating ( = 0.250) remained statistically unchanged, yet the incidence and intensity of diarrhoea improved significantly after receiving the intervention feed (Z = -2.271, = 0.023). Compliance with the intervention feed was significantly greater compared to the patient's baseline regimens (99% vs. 87%, = 0.038). Compared to baseline, use of the intervention feed enabled patients to significantly increase total energy (1676 kcal/day (SD 449) to 1884 kcal/day (SD 537), = 0.039) and protein intake (73 g/day (SD 17) to 89 g/day (SD 23), = 0.001), allowing patients to better achieve energy (from 88% to 99%, = 0.038) and protein (from 101% to 121%, < 0.001) requirements. This pilot study demonstrates that a high-energy, high-protein, peptide-based, MCT-containing enteral tube feed maintains gastrointestinal tolerance and improves compliance, energy and protein intake in complex, enterally tube-fed, community-based adult patients, though more work is recommended to confirm this
The Impact of COVID-19 Pandemic on Adult and Pediatric Allergy & Immunology Services in the UK National Health Service.
No full textBACKGROUND
The COVID-19 pandemic imposed multiple restrictions on healthcare services.
OBJECTIVE
To investigate the impact of the pandemic on Allergy & Immunology (A&I) services in the UK.
METHODS
National survey of all A&I services registered with the Royal College of Physicians and/or British Society for Allergy and Clinical Immunology. The survey covered staffing, facilities, personal protective equipment, appointments & patient review, investigations, treatments and research activity. Weeks commencing 03 Feb'20 (pre-COVID), 06 April'20 and 08'May'20 were used as reference points for the dataset.
RESULTS
99 services participated. There was a reduction in nursing, medical, administrative and allied health professional staff during pandemic; 86% and 92% of A&I services continued to accept non-urgent and urgent referrals respectively during the pandemic. There were changes in immunoglobulin (Ig) dose and infusion regimen in 67% and 14% of adult and pediatric services respectively; 30% discontinued immunoglobulin replacement in some patients. There was a significant (all variables, p≤0.0001) reduction in the following: face-to-face consultations (increase in telephone consultations), initiation of venom immunotherapy, sublingual and subcutaneous injection immunotherapy, anesthetic allergy testing and hospital procedures (food challenges, immunoglobulin and omalizumab, administration); and a significant increase (p≤0.0001) in home therapy for immunoglobulin and omalizumab. Adverse clinical outcomes were reported, but none were serious.
CONCLUSION
The pandemic had significant impact on A&I services leading to multiple unplanned pragmatic amendments in service delivery. There is an urgent need for prospective audits and strategic planning in the medium and long term to achieve equitable, safe and standardised healthcare
Unusual presentations of cutaneous larva migrans in British military personnel.
No full textCutaneous 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)
