Background: Acute ischemic stroke (AIS) is a life-threatening complication of coronavirus disease 2019 (COVID-19) infection. Increasing reports suggest an association between COVID-19 and AIS, although the underlying mechanism remains uncertain. Objectives: We performed a systematic review to characterize the clinical characteristics, neuroimaging findings, and outcomes of AIS in COVID-19 patients. Methods: A literature search was performed in PubMed and Embase using a suitable keyword search strategy from 1st December 2019 to 29th May 2020. All studies reporting AIS occurrence in COVID-19 patients were included. Results: A total of 39 studies comprising 135 patients were studied. The pooled incidence of AIS in COVID-19 patients from observational studies was 1.2% (54/4466) with a mean age of 63.4 ± 13.1 years. The mean duration of AIS from COVID-19 symptoms onset was 10 ± 8 days, and the mean NIHSS score was 19 ± 8. Laboratory investigations revealed an elevated mean D-dimer (9.2 ± 14.8 mg/L) and fibrinogen (5.8 ± 2.0 g/L). Antiphospholipid antibodies were detected in a significant number of cases. The majority of AIS neuroimaging patterns observed was large vessel thrombosis, embolism or stenosis (62.1%, 64/103), followed by multiple vascular territory (26.2%, 27/103). A high mortality rate was reported (38.0%, 49/129). Conclusion: We report the pooled incidence of AIS in COVID-19 patients to be 1.2%, with a high mortality rate. Elevated D-dimer, fibrinogen and the presence of antiphospholipid antibodies appear to be prominent in COVID-19 patients with concomitant AIS, but further mechanistic studies are required to elucidate their role in pathogenesis.

The coronavirus disease 2019 (COVID-19) pandemic has caused millions of deaths worldwide. Acute ischemic stroke is a life-threatening risk factor for COVID-19 infection. Neutrophil-to-lymphocyte ratio (NLR) is one of the predictors of poor prognosis in acute ischemic stroke. The aim of this study was to assess the correlation between NLR values and the clinical outcome of acute thrombotic stroke patients with COVID-19 that was measured using the National Institutes of Health Stroke Scale (NIHSS). A cross-sectional hospital-based study was conducted in Dr. Soetomo General Hospital Surabaya, Indonesia. Patients with acute thrombotic stroke and COVID-19 admitted between 1 March 2020 and 31 May 2021 were recruited. The NLR values and the NIHSS scores were assessed during the admission and the correlation between NLR and NIHSS scores was calculated. This study included 21 patients with acute thrombotic stroke and COVID-19, consisting of 12 males and 9 females. The mean age was 57.6 years old. The mean NLR values was 8.33±6.7 and the NIHSS scores ranging from 1 to 33. Our data suggested a positive correlation between NLR values and NIHSS scores, r=0.45 with p=0.041. In conclusion, the NLR value is potentially to be used as a predictor of the clinical outcome in acute thrombotic stroke patients with COVID-19. However, further study is warranted to validate this finding.

Abstract Pulmonary embolism (PE) is a common, potentially life-threatening yet treatable condition. Prompt diagnosis and expeditious therapeutic intervention is of paramount importance for optimal patient management. Our objective was to systematically review the accuracy of D-dimer assay, compression ultrasonography (CUS), computed tomography pulmonary angiography (CTPA), and ventilation-perfusion (V/Q) scanning for the diagnosis of suspected first and recurrent PE. We searched Cochrane Central, MEDLINE, and EMBASE for eligible studies, reference lists of relevant reviews, registered trials, and relevant conference proceedings. 2 investigators screened and abstracted data. Risk of bias was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 and certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework. We pooled estimates of sensitivity and specificity. The review included 61 studies. The pooled estimates for D-dimer sensitivity and specificity were 0.97 (95% confidence interval [CI], 0.96-0.98) and 0.41 (95% CI, 0.36-0.46) respectively, whereas CTPA sensitivity and specificity were 0.94 (95% CI, 0.89-0.97) and 0.98 (95% CI, 0.97-0.99), respectively, and CUS sensitivity and specificity were 0.49 (95% CI, 0.31-0.66) and 0.96 (95% CI, 0.95-0.98), respectively. Three variations of pooled estimates for sensitivity and specificity of V/Q scan were carried out, based on interpretation of test results. D-dimer had the highest sensitivity when compared with imaging. CTPA and V/Q scans (high probability scan as a positive and low/non-diagnostic/normal scan as negative) both had the highest specificity. This systematic review was registered on PROSPERO as CRD42018084669.

BackgroundEndovascular therapy (EVT) for acute ischemic stroke (AIS) can be challenging in older patients with supra-aortic tortuosity. Rescue carotid puncture (RCP) can be an alternative in case of supra-aortic catheterization failure by femoral access, but data regarding RCP are scarce. We sought to investigate the feasibility, effectiveness and safety of RCP for AIS treated by EVT.MethodsPatients treated by EVT with RCP were included from January 2012 to December 2019 in the Endovascular Treatment in Ischemic Stroke (ETIS) multicentric registry. Main outcomes included reperfusion rates (≥TICI2B), 3 month functional outcome (modified Rankin Scale) and 3 month mortality. We also performed an additional systematic review of the literature according to the PRISMA checklist to summarize previous studies on RCP.Results25 patients treated by EVT with RCP were included from the ETIS registry. RCP mainly concerned elderly patients (median age 85 years, range 73–92) with supra-aortic tortuosity (n=16 (64%)). Intravenous thrombolysis (IVT) was used for nine patients (36%). Successful reperfusion was achieved in 64%, 87.5% of patients were dependent at 3 months, and 3 month mortality was 45.8%. The systematic review yielded comparable results. In pooled individual data, there was a shift toward better functional outcome in patients with successful reperfusion (median (IQR) 4 (2–6) vs 6 (4–6), p=0.011).ConclusionRCP mainly concerned elderly patients admitted for AIS with anterior LVO with supra-aortic tortuosity. The procedure seemed feasible, notably for patients treated with IVT, and led to significant reperfusion rates at the end of procedure, but with pronounced unfavorable outcomes at 3 months. RCP should be performed under general anesthesia to avoid life-threatening complications and ensure airways safety. Finally, RCP led to low rates of closure complications, emphasizing that this concern should not withhold RCP, if indicated.

Chronic Granulomatous Disease (CGD) represents recurrent life-threatening bacterial and fungal infections and granuloma formation with a high mortality rate. CGD’s sign and symptoms usually appear in infancy and children before the age of five; therefore, its presentation in neonatal period with some uncommon features may be easily overlooked. Here we describe a case of CGD in a 24-day-old boy, presenting with a diffuse purulent vesiculopustular rash and multiple osteomyelitis.

SummaryIntroduction.The reason for using thrombolytic therapy is to eliminate vascular thrombosis and promote vascular permeability. Acute limb ischemia is associated with significant morbidity and mortality. ROCHESTER, STILE and TOPAS studies showed that thrombolytic therapy for acute limb ischemia decreases the rate of surgical interventions and significantly increases the rate of limb salvage.Aim of the Study.The purpose of this study is to assess the efficacy and outcomes of intra-arterial thrombolysis in the treatment of acute occlusions of the lower limb over a four-year period.Material and Methods.We analysed 103 patients who had been treated in our department. There were acute ischemias of stage IIa and IIb according to the Rutherford classification. The data prior to, and after thrombolysis was analysed. We usedAlteplaseas a thrombolytic agent (mean dose 62 mg ±23.5). Procedural success was based on angiographic and clinical outcomes. Statistics were calculated by SPSS 16.Results.The mean duration of symptoms prior to hospitalisation was 2.5 days (IQR 5-96 hours). The mean age at the time of thrombolysis was 63±11 for males 69±10 years for females. The success of intraarterial thrombolysis was defined by angiographic and clinical outcomes (successful in 86.4% and failed in 13.6%). Adjunctive angioplasty was performed on 39 (37.9%) patients, and immediate reconstructive surgery was required on 19 (18.4%) patients. The incidence of complications was 17,4 %, with the most common being-bleeding from the puncture side, the urinary tract or the gastrointestinal tract. Overall mortality was 8.7%. The women who required thrombolysis were older (p=0,034) and with a higher death rate (p=0.047). A CDT (catheter-directed thrombolysis) for an abdominal aorta thrombosis carries a significantly high mortality rate (p=0.00013). There were no statistically significant differences between the duration of symptoms and limb amputation and between other analysed data.Conclusions.Intraarterial thrombolysis is an effective treatment method in acute limb ischemia for selected patients, as long as accurate procedural monitoring is ensured. Thrombolysis often leads to the discovery of underlying vascular lesions. A CDT for an abdominal aorta thrombosis carries a significantly high mortality rate.

AbstractObjective:We report lateral sinus thrombosis occurring as a rare complication following a routine and uneventful otological procedure.Case report:Lateral sinus thrombosis is a rare but known complication of otitis media. It has not been documented as a complication of routine otological surgery. We present a case of this rare complication following a myringoplasty. We also discuss the presentation, investigation and treatment of lateral sinus thrombosis. It is essential to be able to recognise and treat this rare complication early, due to its high mortality rate.Conclusion:Lateral sinus thrombosis is a rare but potentially life-threatening complication. It is therefore essential for clinicians to be able to recognise and treat this condition early.

Bronchial complications are among the main causes of impairing postoperative period and thansplant failure. Severe bronchial complications are very rare but have a high mortality rate. Light forms decrease transplant function and while progressing can leads to life-threatening conditions without required treatment. Nowadays there is a huge necessity in classification of diagnostic and bronchial complications treatment on different terms after lung transplantation. Methods of observation bronchoscopy and interventional bronchology are allowing us to realize prevention, diagnostic and treatment bronchial complications.

Background: Women are more affected by stroke than men. This might, in part, be explained by sex differences in stroke pathophysiology. The hemostasis system is influenced by sex hormones and associated with female risk factors for stroke, such as migraine.Aim: To systematically review possible sex differences in hemostatic related factors in patients with ischemic stroke in general, and the influence of migraine on these factors in women with ischemic stroke.Results: We included 24 studies with data on sex differences of hemostatic factors in 7247 patients with ischemic stroke (mean age 57–72 years, 27–57% women) and 25 hemostatic related factors. Levels of several factors were higher in women compared with men; FVII:C (116% ± 30% vs. 104% ± 30%), FXI (0.14 UI/mL higher in women), PAI-1 (125.35 ± 49.37 vs. 96.67 ± 38.90 ng/mL), D-dimer (1.25 ± 0.31 vs. 0.95 ± 0.24 μg/mL), and aPS (18.7% vs. 12.0% positive). In contrast, protein-S (86.2% ± 23.0% vs. 104.7% ± 19.8% antigen) and P-selectin (48.9 ± 14.4 vs. 79.1 ± 66.7 pg/mL) were higher in men. Most factors were investigated in single studies, at different time points after stroke, and in different stroke subtypes. Only one small study reported data on migraine and hemostatic factors in women with ischemic stroke. No differences in fibrinogen, D-dimer, t-PA, and PAI-1 levels were found between women with and without migraine.Conclusion: Our systematic review suggests that sex differences exist in the activation of the hemostatic system in ischemic stroke. Women seem to lean more toward increased levels of procoagulant factors whereas men exhibit increased levels of coagulation inhibitors. To obtain better insight in sex-related differences in hemostatic factors, additional studies are needed to confirm these findings with special attention for different stroke phases, stroke subtypes, and not in the least women specific risk factors, such as migraine.

Abstract Background and Purpose To determine reasons for failed recanalization in mechanical thrombectomy (MT) of the posterior circulation. Methods Retrospective single center analysis of reasons for MT failure in the posterior circulation. Failed MTs were categorized according to the reason for procedure failure in failed vascular access, failed passage of the target vessel occlusion and MT failure after passing the occluded target vessel. Patient characteristics were compared between failed and successful MT. Results Patients with failed MT (30/218 patients, 13.8%) were categorized into futile vascular access (13/30, 43.3%), abortive passage of the target vessel occlusion (6/30, 20.0%) and MT failure after passing the vessel occlusion (11/30, 36.7%). In 188/218 (86.2%) successful MTs alternative vascular access, local intra-arterial (i.a.) thrombolysis and emergency stent-assisted PTA prevented 65 MT failures. Patients with failed MT showed a higher NIHSS at discharge, a higher pc-ASPECTS in follow-up imaging, a higher mRS 90 days after stroke onset and a high mortality rate of 77.0% (mRS at 90 days, median (IQR): 6 (6–6) vs. 4 (2–6) for successful MT, p-value < 0.001). Co-morbidities and stroke etiology were not different compared to sufficient recanalization with atherosclerotic disease as the leading stroke etiology in both groups. Conclusion Failure of MT in posterior circulation ischemic stroke patients is associated with a high mortality rate. Reasons for MT failure are diverse with futile vascular access and MT failure after passing the vessel occlusion as the leading causes. Alternative vascular access, local i.a. thrombolysis and stent-assisted PTA can prevent MT failure.
