Recent randomized controlled trials have transformed the treatment of acute ischemic stroke. Mechanical or aspiration thrombectomy is the main treatment option for occlusions of large intracranial vessels. Despite its high technical success rate, endovascular thrombectomy can sometimes be complicated by anatomical peculiarities or device failures. The most frequent complications are related to vessel dissection or vessel perforation by devices while navigating intricate anatomy. Rarer still are technical device failures, like spontaneous stent-retriever detachment, which occurred with older generation retrievers. This case reports a rare device failure, which, to the best of our knowledge, has not been reported in the literature so far, namely a microwire fracture in the middle cerebral artery. This was successfully removed with an Eric stent-retriever. The potential causes and possible management strategies are discussed.

Introduction: Patients on extracorporeal membrane oxygenator (ECMO) therapy are critically ill and often develop acute kidney injury (AKI) during hospitalisation. Little is known about the association of exposure to and the effect of the type of ECMO and extent of renal recovery after AKI development. Aim of the study: In patients who developed AKI, renal recovery was characterised as complete, partial or dialysis-dependent at the time of hospital discharge in both the Veno-Arterial (VA) and Veno-Venous (VV) ECMO treatment groups.
Material and methods: The study consisted of a single-centre retrospective cohort that includes all adult patients (n=125) who received ECMO treatment at a tertiary academic medical centre between 2015 to 2019. Data on demographics, type of ECMO circuit, comorbidities, exposure to nephrotoxic factors and receipt of renal replacement therapy (RRT) were collected as a part of the analysis. Acute Kidney Injury Network (AKIN) criteria were used for the diagnosis and classification of AKI. Group differences were assessed using Fisher’s exact tests for categorical data and independent t-tests for continuous outcomes.
Results: Sixty-four patients received VA ECMO, and 58 received VV ECMO. AKI developed in 58(91%) in the VA ECMO group and 51 (88%) in the VV ECMO group (p=0.77). RRT was prescribed in significantly higher numbers in the VV group 38 (75%) compared to the VA group 27 (47%) (p=0.0035). At the time of discharge, AKI recovery rate in the VA group consisted of 15 (26%) complete recovery and 5 (9%) partial recovery; 1 (2%) remained dialysis-dependent. In the VV group, 22 (43%) had complete recovery (p=0.07), 3(6%) had partial recovery (p=0.72), and 1 (2%) was dialysis-dependent (p>0.99). In-hospital mortality was 64% in the VA group and 49% in the VV group (p=0.13).
Conclusions: Renal outcomes in critically ill patients who develop AKI are not associated with the type of ECMO used. This serves as preliminary data for future studies in the area.

Pulmonary hypertension is a rare and progressive pathology defined by abnormally high pulmonary artery pressure mediated by a diverse range of aetiologies. It affects up to twenty-six individuals per one million patients currently living in the United Kingdom (UK), with a median life expectancy of 2.8 years in idiopathic pulmonary hypertension. The diagnosis of pulmonary hypertension is often delayed due to the presentation of non-specific symptoms, leading to a delay in referral to specialists services. The complexity of treatment necessitates a multidisciplinary approach, underpinned by a diverse disease aetiology from managing the underlying disease process to novel specialist treatments. This has led to the formation of dedicated specialist treatment centres within centralised UK cities. The article aimed to provide a concise overview of pulmonary hypertension’s clinical perioperative management, including key definitions, epidemiology, pathophysiology, and risk stratification.

Introduction: Viral bronchiolitis is a leading cause of admissions to pediatric intensive care unit (PICU). A literature review indicates that there is limited information on fluid overload and the use of diuretics in mechanically ventilated children with viral bronchiolitis. This study was conducted to understand diuretic use concerning fluid overload in this population.
Material and methods: A retrospective cohort study performed at a quaternary children’s hospital. The study population consisted of mechanically ventilated children with bronchiolitis, with a confirmed viral diagnosis on polymerase chain reaction (PCR) testing. Children with co-morbidities were excluded. Data collected included demographics, fluid status, diuretic use, morbidity and outcomes. The data were compared between groups that received or did not receive diuretics.
Result: Of the 224 mechanically ventilated children with confirmed bronchiolitis, 179 (79%) received furosemide on Day 2 of invasive ventilation. Out of these, 72% of the patients received intermittent intravenous furosemide, whereas 28% received continuous infusion. It was used more commonly in patients who had a higher fluid overload. Initial fluid overload was associated with longer duration of mechanical ventilation (median days 6 vs 4, p<0.001) and length of stay (median days 10 vs 6, p<0.001) even with the use of furosemide. Superimposed bacterial pneumonia was seen in 60% of cases and was associated with a higher per cent fluid overload at 24 hours (9.1 vs 6.3, p = 0.003).
Conclusion: Diuretics are frequently used in mechanically ventilated children with bronchiolitis and fluid overload, with intermittent dosing of furosemide being the commonest treatment. There is a potential benefit of improved oxygenation in these children, though further research is needed to quantify this benefit and any potential harm. Due to potential harm with fluid overload, restrictive fluid strategies may have a potential benefit.

Erratum

This is a correction for the article Bilateral Ocular Exophthalmia – A Case of Atypical Acute Myeloblastic Leukemia in a Child, published by Réka Toth, Alina Grama, Cristina Maki and Mihaela Ioana Chinceșan in The Journal of Critical Care Medicine 2020;6(4):243-248, DOI: 10.2478/jccm-2020-0031.
The authors received a complaint regarding the publication of the results of genetic analyzes without the consent of the Medical Genetics Laboratory from the Emergency Clinical County Hospital of Targu Mures. At the written request of the authors, the following paragraphs from page 246 will be removed from the published manuscript:

“The FLT3 D835 and DNMT3A R882 mutation was performed by polymerase chain reaction-restriction fragment length polymorphism. For FLT3 ITD and NPM1 fragment analysis was also executed with capillary electrophoresis. Geneticists did not detect any mutations of examined fragments. Quantitative analysis showed FTL3-ITD:VAR=0% and NPM1:VAR=0.08%. The heterozygous deletion was shown at the level of the 2p24.3 region (for exons 2, 3 of the MYCN gene), no copy number variants for the other investigated regions was evidenced, and mutation of JAK3 V617F was not detected.”

This will not affect the information presented in the manuscript, nor the conclusions.

Introduction: There is limited data on the impact of extracorporeal membrane oxygenation (ECMO) on pulmonary physiology and imaging in adult patients. The current study sought to evaluate the serial changes in oxygenation and pulmonary opacities after ECMO initiation.
Methods: Records of patients started on veno-venous, or veno-arterial ECMO were reviewed (n=33; mean (SD): age 50(16) years; Male: Female 20:13). Clinical and laboratory variables before and after ECMO, including daily PaO2 to FiO2 ratio (PFR), were recorded. Daily chest radiographs (CXR) were prospectively appraised in a blinded fashion and scored for the extent and severity of opacities using an objective scoring system.
Results: ECMO was associated with impaired oxygenation as reflected by the drop in median PFR from 101 (interquartile range, IQR: 63-151) at the initiation of ECMO to a post-ECMO trough of 74 (IQR: 56-98) on post-ECMO day 5. However, the difference was not statistically significant. The appraisal of daily CXR revealed progressively worsening opacities, as reflected by a significant increase in the opacity score (Wilk’s Lambda statistic 7.59, p=0.001). During the post-ECMO period, a >10% increase in the opacity score was recorded in 93.9% of patients. There was a negative association between PFR and opacity scores, with an average one-unit decrease in the PFR corresponding to a +0.010 increase in the opacity score (95% confidence interval: 0.002 to 0.019, p-value=0.0162). The median opacity score on each day after ECMO initiation remained significantly higher than the pre-ECMO score. The most significant increase in the opacity score (9, IQR: -8 to 16) was noted on radiographs between pre-ECMO and forty-eight hours post-ECMO. The severity of deteriorating oxygenation or pulmonary opacities was not associated with hospital survival.
Conclusions: The use of ECMO is associated with an increase in bilateral opacities and a deterioration in oxygenation that starts early and peaks around 48 hours after ECMO initiation.

As we are writing this editorial 12 months following the publication of “The 2019 Novel Coronavirus: A Crown Jewel of Pandemics?”, there are 96 million cases with over 2 million total deaths, a public health tragedy of staggering proportions [1]. The early stages of the pandemic were characterized by scientific uncertainty, with many authors postulating hypotheses about the transmission of SARS-CoV-2, the appropriate medical treatment, and the most effective public health measures. In retrospect, many of the early takes on coronavirus ended up being incorrect. Since January 2020, science has advanced at a breathtaking pace and the disease caused by SARS-CoV-2 has taken on dimensions few of us anticipated. In this piece, we aim to reflect on the last year, discussing aspects of the pandemic that the scientific community correctly anticipated, and highlighting where we went wrong. [More]

Background: Recent studies have reported that COVID-19 infected patients with stroke, who were often in the older age group, had a higher incidence of vascular risk factors, and more severe infection related respiratory symptoms. These observations provided little evidence to suggest that COVID-19 infection is a potential causative factor for stroke. This report describes a young patient with a cerebellar stroke secondary to COVID-19 infection.
Case presentation: A 45-year old male presented at a hospital, reporting a two-day history of headache, vertigo, persistent vomiting, and unsteady gait. Physical examination revealed gaze-evoked nystagmus on extraocular movement testing, left-sided dysmetria and dysdiadochokinesia. He was diagnosed with a left cerebellar stroke. An external ventricular drain was inserted, and sub-occipital craniectomy was performed to manage the effects of elevated intracranial pressure due to the extent of oedema secondary to the infarct. He also underwent screening for the COVID-19 infection, which was positive on SARS-COV-2 polymerase chain reaction testing of his endotracheal aspirate. Blood and cerebrospinal fluid samples were negative. After the surgery, the patient developed atrial fibrillation and had prolonged vomiting symptoms, but these resolved eventually with symptomatic treatment. He was started on aspirin and statin therapy, but anticoagulation was withheld due to bleeding concerns. The external ventricular drain was removed nine days after the surgery. He continued with active rehabilitation.
Conclusions: Young patients with COVID-19 infection may be more susceptible to stroke, even in the absence of risk factors. Standard treatment with aspirin and statins remains essential in the management of COVID-19 related stroke. Anticoagulation for secondary prevention in those with atrial fibrillation should not be routine and has to be carefully evaluated for its benefits compared to the potential harms of increased bleeding associated with COVID-19 infection.

DOI: 10.2478/jccm-2021-0003

Introduction: Laryngeal oedema caused by acquired angioedema due to C1-inhibitor deficiency (C1-INH-AAE) is a life-threatening condition. The swelling is bradykinin mediated and will not respond to the usual treatment with antihistamines, corticosteroids, or epinephrine. Instead, kallikrein-bradykinin-targeted therapies should be used promptly to prevent asphyxiation.
Case presentation: A 43 years old female presented at the Hereditary Angioedema Centre reporting a one-year history of peripheral, facial, and neck oedema. Treatment with antihistamines and corticosteroids had been ineffective. Laboratory results showed complement level deficiencies and monoclonal gammopathy characterised as immunoglobulin M. An abdominal ultrasound revealed splenomegaly. A bone marrow biopsy was normal. Based on these data, the diagnosis of C1-INH-AAE associated with monoclonal gammopathy of uncertain significance (MGUS) was made. As C1-INH-AAE can present with life-threatening, standard treatment-resistant laryngeal oedema, an emergency care treatment plan was proposed, and the patient was advised to present to the emergency department (ED) with this medical letter. Based on these recommendations, three laryngeal attacks were successfully treated in the ED with recombinant human C1-inhibitor (two attacks) and fresh frozen plasma (one attack). After these episodes, the patient was prescribed prophylactic treatment with antifibrinolytics. No further angioedema attacks were reported by the patient at the 18 months follow-up visit.
Conclusions: Because angioedema of the upper airways is a life-threatening condition, recognising the specific type of swelling by the emergency physician is critical in providing immediate and effective treatment to reduce the associated risk of asphyxiation. C1-INH-AAE being a rare disorder, patients should have available an emergency care treatment plan with recommendations of acute treatment possibilities.
