Acute eosinophilic pneumonia-like syndrome post-initiation of vortioxetine.

A man in his mid-30s presented to the emergency department with a 1-week history of fatigue, loss of appetite, fever and productive (yellow) cough. This progressed to requiring admission to intensive care needing a oxygen therapy via high-flow nasal cannula for acute hypoxaemic respiratory failure. He had recently started vortioxetine for major depressive disorder, and his acute symptoms correlated with an increase in the dose of vortioxetine. For more than 20 years, rare but consistent reports of serotonergic medications have been implicated in eosinophilic pulmonary conditions. During this same period, serotonergic medications have become a mainstay solution for a wide range of depressive symptoms and disorders. This is the first report of an eosinophilic pneumonia-like syndrome occurring while consuming the novel serotonergic medication vortioxetine.

Refractory atrial fibrillation with rapid ventricular response as a heralding sign of propofol infusion syndrome in a patient with COVID-19.

A woman in her 40s was transferred to the medical intensive care unit due to severe COVID-19 infection causing respiratory failure. Her respiratory failure worsened rapidly, requiring intubation and continuous sedation with fentanyl and propofol infusions. She required progressive increases in the rates of the propofol infusion, as well as addition of midazolam and cisatracurium due to ventilator dyssynchrony. To support the high sedative doses, norepinephrine was administered as a continuous infusion. She developed atrial fibrillation with rapid ventricular response, with rates ranging between 180 and 200 s which did not respond to intravenous adenosine, metoprolol, synchronised cardioversion or amiodarone. A blood draw revealed lipaemia, and triglyceride levels were noted to be elevated to 2018. The patient developed high-grade fevers up to 105.3 and acute renal failure with severe mixed respiratory and metabolic acidosis, indicating propofol-related infusion syndrome. Propofol was promptly discontinued. An insulin-dextrose infusion was initiated which improved patient's fevers and hypertriglyceridaemia.

Atypical case of infective endocarditis.

A man in his late 40s presented to the emergency department with generalised tiredness and breathlessness. He was a known case of chronic obstructive pulmonary disease and also had a recent history of COVID-19. At arrival, he was in respiratory failure. Blood culture grew Streptococcus parasanguinis, a commensal gram-positive bacterium and a primary coloniser of the human oral cavity. Echocardiogram revealed the presence of a flail mitral valve with vegetation suggestive of infective endocarditis. Although biomarkers of inflammation/infection had improved, he continued to be in cardiac failure, and hence he underwent mitral valve replacement with a mechanical valve. This case is unique in many ways; the patient was young, had a history of COVID-19, had native valve infective endocarditis and presented with type 2 respiratory failure and not the usual 'typical' manifestations of infective endocarditis. He had refractory heart failure requiring early valve replacement. His blood culture grew S. parasanguinis, a rare cause for infective endocarditis.

[Traumatic motherhood in Covid-19 times]. / Maternités traumatiques en temps de Covid-19.

In the context of maternal vital emergency due to Covid-19, dire situations of birth questioned the health practitioners of a neonatal intensive care unit. How can mothers take care of their baby when their own life has been threatened ? The analysis of two clinical cases underlines the importance of talking for these mothers who have been through disastrous experiences, which could lead to a post-traumatic stress disorder. Restoring a connection to outside reality thanks to psychological care in the acute post-trauma period helps these mothers take care of their child.

Unusual case of propofol-related infusion syndrome complicating severe COVID-19 ARDS.

An elderly man presenting with shortness of breath and hypoxaemia was admitted with acute hypoxic respiratory failure secondary to COVID-19 pneumonia. Due to worsening hypoxaemia, he was transferred to the intensive care unit and required mechanical ventilation. Propofol was infused at 1.5-4 mg/kg/hour. Within 48 hours of initiation, we noticed worsening metabolic acidosis, acute kidney injury, hyperkalaemia, hyperphosphataemia, hypertriglyceridaemia, elevated creatine kinase and elevated myoglobin levels. Suspecting propofol-related infusion syndrome (PRIS), we discontinued his propofol infusion immediately and initiated supportive measures. In 48 hours, there was a significant improvement in metabolic acidosis, hypertriglyceridaemia, rhabdomyolysis and renal function. The propofol infusion rate and cumulative propofol dosage (under 140 mg/kg) were well below levels associated with PRIS. COVID-19's pathogenesis, still under investigation, may have contributed to this presentation. It is imperative for clinicians to maintain a high degree of suspicion once propofol is initiated, regardless of the cumulative dose or rate of infusion.

Surgical management of pneumomediastinum in the COVID-19 patient.

As the SARS-CoV-2 virus continues to infect millions of people worldwide, the medical profession is seeing a wide range of short-term and long-term complications of COVID-19. One lesser-known complication is that of pneumomediastinum. This is a rare, but significant, complication defined by the presence of air in the mediastinum with an incidence of 1.2 per 100 000. Described mortality rate is 30%, increasing to 60% in patients with concomitant pneumothoraces. Management of pneumomediastinum is typically conservative, but in cases of extensive subcutaneous emphysema, cardiac or airway compression, life-saving surgical decompression is necessary. We report a case of pneumomediastinum secondary to COVID-19, requiring a surgical approach not described in pneumomediastinum secondary to COVID-19. The case demonstrates the importance of prompt diagnosis and management, as well as the potential for good clinical outcome in selected patients.

Case of myocarditis secondary to severe Plasmodium falciparum infection.

Malaria remains one of the most prevalent infectious diseases globally. Despite targets set out by the WHO in 2015, there has been a rise in the number of cases since 2019 as an indirect effect of the COVID-19 pandemic.Cardiac complications are very rarely witnessed with severe malaria. Of the cardiac sequelae, myocarditis is one of the most frequently observed with a handful of case reports in the literature. We report a case of a man in his 50s who developed myocarditis while being managed for severe Plasmodium falciparum malaria in an intensive care unit in the UK and review the literature relevant to this case. This is the second reported case of this condition in the UK.

Rare atypical presentation of a polymicrobial gastropericardial fistula.

We present the unique case of a gastropericardial fistula with a rare, delayed presentation in a man in his 70s. Relevant surgeries include Watchman Left Atrial Appendage Closure device placement 1 year prior to arrival and gastric bypass surgery 20 years prior to arrival. The patient presented to the emergency department with weakness, diarrhoea and left knee pain. He was admitted for cellulitis of the left lower extremity, prosthetic septic arthritis of the left knee and group G streptococcus bacteraemia. His hospital course was complicated by acute chest pain and dyspnoea. Imaging revealed pneumopericardium. Oesophagogastroduodenoscopy visualisation confirmed the diagnosis of gastropericardial fistula. The patient could not be transferred to a tertiary centre for definitive management because of the effect of the COVID-19 pandemic on tertiary hospital volumes. After pericardial drainage and administration of antimicrobials without improvement, the patient was discharged to hospice care at his request and died 1 day after discharge.

Cerebral microvascular injuries in severe COVID-19 infection: progression of white matter hyperintensities post-infection.

A range of neuroradiological findings has been reported in patients with COVID-19, some mimicking cerebral small vessel disease (CSVD). We present a case of a man in his 50s with severe COVID-19, who was Glasgow Coma Scale 3 and tetraparetic after sedation was ceased in the intensive care unit. Return of consciousness and motor activity was slow. An MRI 1 month after debut of symptoms demonstrated white matter hyperintensities on T2-weighted Fluid Attenuated Inversion Recovery (T2-FLAIR) and many small areas with impaired diffusion in primarily supratentorial and infratentorial white matter on Diffusion-Weighted Imaging (DWI). In the following months, the patient made a remarkable clinical recovery. Despite clinical improvement, an MRI after 7 months showed that white matter hyperintensities had progressed and become confluent. Both MRIs demonstrated findings resembling CSVD, which could relate to a COVID-19-specific process affecting cerebral microvasculature.

Bicaval dual lumen cannula placement using transthoracic echocardiography in COVID-19 scenario: pearls and pitfalls.

A woman in her 50s who had been diagnosed with COVID-19 developed deep vein thrombosis in the left femoral vein extending into inferior vena cava (IVC). An IVC filter was placed to prevent fatal pulmonary embolism. Her respiratory failure subsequently deteriorated despite optimal mechanical ventilation and required venovenous extracorporeal membrane oxygenation (VV-ECMO) as a rescue therapy. Femoro-jugular VV-ECMO configuration was not suitable due to the IVC filter, hence a single-site venous cannulation using bicaval dual lumen (AvalonElite) cannula was selected. Placement of the Avalon cannula conventionally requires guidance by fluoroscopy or transoesophageal echocardiography, which were not feasible in COVID-19 patients. Hence, transthoracic echocardiography guidance was chosen. Guidewire looping into the right ventricle might lead to cannula malposition and imminent right ventricular rupture, but these could be detected by 'bending' sign. Transthoracic echocardiography could be a feasible guidance method for Avalon cannulation, nonetheless a thorough protocol should be followed to avoid cannula malposition during the procedure.

Purpura fulminans due to Streptococcus pneumoniae bacteraemia in an unsplectomised immunocompetent adult without primary hypocomplementaemia.

Invasive pneumococcal disease occurs in high-risk patient population which includes patients with asplenia and primary hypocomplementaemia. Pneumococcal sepsis can rarely cause disseminated intravascular coagulation (DIC) and intravascular thrombosis of small and medium sized vessels called purpura fulminans which is associated with a high mortality rate. We present the case of an immunocompetent woman in her 50s with an intact spleen who presented with septic shock from Streptococcus pneumoniae bacteraemia. Her hospital course rapidly progressed to multiorgan dysfunction, DIC and purpura fulminans. She was treated aggressively with broad spectrum antibiotics, coagulation factor replacement, multiple vasopressor support, renal replacement therapy and mechanical ventilator support. Despite aggressive measures, she succumbed to the multiorgan failure.

Vaccine-induced immune thrombocytopaenia and thrombosis (VITT) after COVID-19 vaccination.

COVID-19 represents a global health emergency, causing significant morbidity and mortality. Multiple vaccines have been distributed worldwide to control the spread of this pandemic. Several reports of thrombosis and thrombocytopaenia have been described after vaccination. These have been termed vaccine-induced immune thrombocytopaenia and thrombosis (VITT). We report a fatal case of VITT after receiving the first dose of Ad26.COV2.S vaccine. A man in his 30s developed thrombocytopaenia, massive haemoperitoneum due to spleen rupture and extensive portal and femoral vein thrombosis. The patient rapidly developed multiple organ failure and died. We attributed this condition to the vaccine due to the temporal relationship, presence of thrombosis and thrombocytopaenia, high levels of platelet factor 4 antibodies and exclusion of other diagnoses. Healthcare providers should be aware of such rare but fatal complications of COVID-19 immunisation, as early diagnosis of VITT may improve prognosis by allowing timely appropriate treatment.

Postpartum bilateral lung transplantation in COVID-19 associated respiratory failure.

In critically ill patients with COVID-19, established therapies in the setting of respiratory failure include invasive mechanical ventilation and extracorporeal membrane oxygenation (ECMO). This case report describes a pregnant woman in her 30s who was hospitalised at 35 weeks gestation with moderate COVID-19 disease. Her condition worsened following delivery, and she required intubation, maximum ventilatory support and ECMO. Because of the severe and irreversible nature of her lung disease, she ultimately underwent bilateral lung transplantation. This case showcases lung transplantation as an alternative life-saving option for patients with severe COVID-19 associated respiratory failure refractory to ECMO and mechanical ventilation. Further studies are needed to develop a multidisciplinary approach for patient selection for transplantation within the context of COVID-19 and to assess long-term outcomes.

Management of a severe bilateral pulmonary embolism as a complication of VITT following vaccination with AstraZeneca COVID-19 vaccine.

Since the start of vaccination against COVID-19 viral infection using adenovirus-based vector vaccine (eg, The Oxford-AstraZeneca vaccine, using the modified chimpanzee adenovirus ChAdOx1, and the Johnson & Johnson vaccine, using human adenovirus serotype 26), a rare, but potentially life-threatening complication called vaccine-induced thrombotic thrombocytopenia (VITT) was reported. As the number of cases increases every day, with the increase in the number of vaccinated people all over the world, this complication is a concern to the medical field. We report a case on the acute management of a patient who presented to us with life-threatening bilateral pulmonary embolism as a complication of VITT after the first dose of vaccination with Oxford-AstraZeneca vaccine against COVID-19.

Cold agglutinin disease secondary to severe SARS-CoV-2 treated with eculizumab.

Impaired immune response with uncontrolled inflammation and various immunological disorders have been reported during SARS-CoV-2 infection. Here, we report a case of cold agglutinin disease occurring during a severe coronavirus disease 2019 (COVID-19) in a French intensive care unit. A patient was presented with acute respiratory distress syndrome, acute renal failure and haemolytic anaemia. Direct antiglobulin test was positive with a cold agglutinin titre of 1/512. No other cause than COVID-19 explained the occurrence of cold agglutinin disease; however, causality could not be formally established. Persistent anaemia despite transfusion therapy and the short-term life-threatening, prompted the infusion of a monoclonal anti-C5 antibody (eculizumab). Eculizumab therapy quasi-fully resolved haemolysis within a few days, but ultimately the patient died from his severe COVID-19 infection. Data regarding the specific treatment of cold agglutinin disease during COVID-19 are rare. Although additional studies are warranted, eculizumab may be considered in critical situations.

Congestion in the tube: air trapping in a ventilated patient with COVID-19 secondary to mucinous valves.

A woman in her 50s was admitted to the intensive therapy unit with acute hypoxaemic respiratory failure secondary to COVID-19 pneumonitis. The patient was intubated on admission and worsening gas exchange necessitated multiple rounds of proning . She later improved, and her ventilation was switched to spontaneous mode. However, the patient started to develop air trapping with subsequent respiratory and cardiovascular compromise. Routine investigations showed no clear cause for her sudden deterioration and a suction catheter passed easily through the endotracheal tube. Bronchoscopy revealed mucinous/phlegmatic membranes had developed across the inner diameter of the endotracheal tube. This had created a one-way valve that allowed positive pressure ventilation through the tube into her lungs but only allowed a fraction of air to passively escape in expiration. This case report highlights a less commonly regarded complication associated with long-term intubation and lack of circuit humidification in the context of productive lung pathology.

Massive pulmonary embolism treated with low-dose thrombolysis on the geriatric ward during the COVID-19 pandemic.

A man in his 70s was admitted to hospital due to a fall, urinary tract infection and delirium. The patient had a 'do not attempt cardiopulmonary resuscitation' order in place and a ward-based ceiling of care was agreed. He tested positive for COVID-19 while on a geriatric ward and subsequently developed bilateral pulmonary emboli with haemodynamic instability. The patient had a significant bleeding risk; however, the expected morbidity and mortality risk from the pulmonary emboli was high. A decision was made to give the patient low-dose thrombolysis on the geriatric ward, following which he made a full recovery. Acute thrombolysis is normally performed in emergency department, high dependency unit (HDU) or intensive care unit (ICU) settings; however, this was not possible in this case due to the burden the COVID-19 pandemic had placed on HDU/ICU services and bed capacity. Adaptation of treatment guidelines allowed for emergency life-saving treatment to be delivered to this patient.

Diabetic ketoacidosis, cerebral venous sinus thrombosis and fulminant cerebral oedema in COVID-19 infection complicated by Klebsiella pneumoniae infection.

We present an unusual case of a woman in her 30s who was admitted for diabetic ketoacidosis (DKA) in the setting of newly diagnosed but late COVID-19 infection with associated Klebsiella pneumoniae infection. Her altered mental status, out of proportion with her metabolic decompensation, revealed a superimposed cerebral venous sinus thrombosis (CVST) with fulminant cerebral oedema and ultimately brain death. This unusual and fulminant case of cerebral oedema in the setting of COVID-19 infection with bacterial infection, DKA and CVST was the perfect storm with multiple interwoven factors. It offered diagnostic and treatment challenges with an unfortunate outcome. This unique case is a reminder that it is important to consider a broad neurological differential in patients with COVID-19 with unexplained neurological manifestations, which may require specific neurointensive care management.

Antisynthetase syndrome sine myositis presenting as severe acute respiratory failure.

A female in her late 40s presented to the emergency department during the COVID-19 pandemic with shortness of breath, fever and productive cough following a recent diagnosis of bilateral non-massive pulmonary emboli. She had elevated inflammatory markers and her chest X-ray revealed bilateral infiltrates. Her SARS-CoV-2 PCR was negative, and she was treated for community-acquired pneumonia. However, despite treatment she rapidly deteriorated and developed severe respiratory failure, requiring mechanical ventilation.On further investigation, she tested positive for anti-Jo-1 antibodies and a diagnosis of antisynthetase syndrome sine myositis was made. This led to successful treatment with high dose corticosteroids and intravenous immunoglobulin.This case highlights an uncommon presentation of a rare condition, as well as the benefits of working in a multidisciplinary team on the intensive care unit.

Acute neurological deficit with submassive pulmonary emboli.

Pulmonary embolism (PE) is frequently encountered in the emergency department. Syncope, often as a consequence of impending haemodynamic collapse, is associated with increased mortality. While loss of consciousness owing to cerebral hypoperfusion and reduced left ventricular preload is a common cause of collapse with large volume PE, other syndromes can also cause neurological deficit in thromboembolic disease. Here, we describe a case of a woman in her 60s, presenting to the emergency department with features of high-risk PE. During clinical examination, the patient collapsed and became unresponsive with a Glasgow Coma Scale of 4/15 despite normal haemodynamics. Neurological signs were noted and CT revealed evidence of a large territory cerebral infarction. Further cardiovascular investigations identified a grade 4 patent foramen ovale. We describe a challenging case of established venous thromboembolism complicated by paradoxical embolism, highlighting the importance of thorough clinical examination and investigation and discuss the current evidence base of treatments.
