RESUMO

Aim: Limited information exists on the factors associated with prolonged procedural time in embolization for trauma patients. We clarified the clinical application of embolization in trauma patients and factors associated with a prolonged procedure time. Methods: Medical records of 162 trauma patients who underwent embolization between January 2007 and December 2020 at a regional trauma care center were reviewed retrospectively. Patients were divided into four embolized body regions: chest, abdomen, pelvis, and other. Patient demographics, trauma mechanism, physiology, trauma severity, embolization procedures, and 30-day mortality were examined. The outcomes were identifying an embolized body region, embolized arteries, and procedure time. Multiple regression model was created to investigate the factors associated with prolonged procedural time in embolization. Results: Embolization was mainly undertaken in pelvic fractures (n = 96, 59%) and abdominal organ injuries (n = 57, 35%) and extended to the chest (n = 17, 10%), and other (n = 20, 12%). Approximately 13% (n = 21) of patients underwent embolization in two or more regions. Embolization was more strictly performed in minor artery injuries, for example, external iliac (n = 15, 16%) and lumbar artery (n = 22, 23%) branches in pelvic fractures, and inferior phrenic artery (n = 2, 3.5%) branches in liver injuries. Multiple regression model indicated that the number of embolized arteries (P = 0.021) and number of embolized regions (P < 0.001) were associated with prolonged procedural time in embolization. Conclusions: Embolization for trauma patients extended to various trauma regions. In time-sensitive embolization, emergency interventional radiologists showed superior knowledge of expected embolizing arteries and factors associated with procedure time.

RESUMO

We report a rare case of negative pressure pulmonary oedema (NPPE), a life-threatening complication of tracheal intubation. A 41-year-old obese man was admitted to a previous hospital for neck surgery. After extubation, he developed respiratory distress followed by haemoptysis and desaturation. The patient was reintubated and brought to our hospital where we introduced venovenous extracorporeal membrane oxygenation (ECMO) to prevent cardiac arrest, which is an unusual clinical course for NPPE. He returned to his routine without any sequelae. This is the first case report of NPPE successfully resolved with venovenous ECMO in the hybrid emergency room (hybrid ER), which is a resuscitation room equipped with interventional radiology features and a sliding CT scanner. Since the hybrid ER serves as a single move for patients where all necessary procedures are performed, it has the potential to lower the incidence of cannulation complications, beyond the delay in ECMO initiation.

RESUMO

BACKGROUND Patients with coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 can rapidly progress to acute respiratory distress syndrome (ARDS). Because clinical diagnosis of ARDS includes several diseases, understanding the characteristics of COVID-19-related ARDS is necessary for precise treatment. We report 2 patients with ARDS due to COVID-19-associated pneumonia. CASE REPORT Case 1 involved a 72-year-old Japanese man who presented with respiratory distress and fever. Computed tomography (CT) revealed subpleural ground-glass opacities (GGOs) and consolidation. Six days after symptom onset, reverse transcription-polymerase chain reaction (RT-PCR) testing confirmed the diagnosis of COVID-19-associated pneumonia. He was intubated and received veno-venous extracorporeal membrane oxygenation (ECMO) 8 days after symptom onset. Follow-up CT revealed large diffuse areas with a crazy-paving pattern and consolidation, which indicated progression of COVID-19-associated pneumonia. Following treatment with antiviral medications and supportive measures, the patient was weaned off ECMO after 20 days. Case 2 involved a 70-year-old Asian man residing in Canada who presented with cough, malaise, nausea, vomiting, and fever. COVID-19-associated pneumonia was diagnosed based on a positive result from RT-PCR testing. The patient was then transferred to the intensive care unit and intubated 8 days after symptom onset. Follow-up CT showed that while the initial subpleural GGOs had improved, diffuse GGOs appeared, similar to those observed upon diffuse alveolar damage. He was administered systemic steroid therapy for ARDS and extubated after 6 days. CONCLUSIONS Because the pattern of symptom exacerbation in COVID-19-associated pneumonia cases seems inconsistent, individual treatment management, especially the CT-based treatment strategy, is crucial.

RESUMO

We investigated the clinical course of individuals with 2019 novel coronavirus disease (COVID-19) who were transferred from the Diamond Princess cruise ship to 12 local hospitals. The conditions and clinical courses of patients with pneumonia were compared with those of patients without pneumonia. Among 70 patients (median age: 67 years) analyzed, the major symptoms were fever (64.3%), cough (54.3%), and general fatigue (24.3%). Forty-three patients (61.4%) had pneumonia. Higher body temperature, heart rate, and respiratory rate as well as higher of lactate dehydrogenase (LDH), aspartate aminotransferase (AST), and C-reactive protein (CRP) levels and lower serum albumin level and lymphocyte count were associated with the presence of pneumonia. Ground-glass opacity was found in 97.7% of the patients with pneumonia. Patients were administered neuraminidase inhibitors (20%), lopinavir/ritonavir (32.9%), and ciclesonide inhalation (11.4%). Mechanical ventilation and veno-venous extracorporeal membrane oxygenation was performed on 14 (20%) and 2 (2.9%) patients, respectively; two patients died. The median duration of intubation was 12 days. The patients with COVID-19 transferred to local hospitals during the outbreak had severe conditions and needed close monitoring. The severity of COVID-19 depends on the presence of pneumonia. High serum LDH, AST and CRP levels and low serum albumin level and lymphocyte count were found to be predictors of pneumonia. It was challenging for local hospitals to admit and treat these patients during the outbreak of COVID-19. Assessment of severity was crucial to manage a large number of patients.

RESUMO

Invasive pulmonary aspergillosis (IPA) usually occurs in patients with severe immunodeficiencies involving neutropenia. Underlying lung disease is a well-known risk factor of IPA; however, interstitial lung disease has not been recognized as a risk factor of IPA. We herein report a patient with fibrotic nonspecific interstitial pneumonia who experienced IPA without neutropenia. His IPA was fatal and showed unusually slow disease progression over one month. The computed tomography findings showed only nonspecific consolidation and no typical lesions suggestive of IPA. Finally, the autoptic findings revealed numerous Aspergillus fungi, neutrophilic pulmonary necrosis, and vessels invaded by Aspergillus fungi.

RESUMO

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been used in refractory hemorrhagic shock patients. Since the optimal timing of arterial access remains unclear, we evaluated the preocclusion status of patients, and elapsed time from the arrival to the hospital is associated with the survival outcomes in the REBOA patients. METHODS: From August 2011 to December 2016, The Diagnostic and Interventional Radiology in Emergency, Critical care and Trauma-Intra-Aortic Balloon Occlusion (DIRECT-IABO) investigators registered refractory hemorrhagic shock patients undergoing REBOA from 23 hospitals in Japan. Patient characteristics, mechanism of injury, Injury Severity Score (ISS), preocclusion and postocclusion systolic blood pressure, duration of aortic occlusion, clinical time course, and survival outcome were recorded and analyzed. Binary logistic regression analysis was used with mortality and Kaplan-Meier survival analysis was conducted to demonstrate the difference between early and delayed access groups. RESULTS: Among the enrolled 207 cases, the following patients were excluded from the analysis: five since they were younger than 18 years, nine due to failed attempts at REBOA, 51 nontrauma patients, and 33 who received resuscitative thoracotomy plus REBOA. Thus, the remaining 109 cases were analyzed (30-day survivors, n = 60; nonsurvivors, n = 49). The preocclusion systolic blood pressure was higher, and both hospital arrival to initial arterial access and duration of occlusion were shorter in the survivors. Lower ISS (odds ratio, 0.944; 95% confidence interval, 0.907-0.982; p = 0.0039) and shorter arrival to access (odds ratio, 0.989; 95% confidence interval, 0.979-0.999; p = 0.034) were significantly associated with 30-day survival in the logistic regression analysis. The cutoff point of 21.5 minutes was used in the receiver operating characteristic analysis. The early access group showed a significantly shorter time of arrival to definitive hemostasis and also demonstrated a significantly higher survival in the Kaplan-Meier survival analysis (p = 0.014, Log-rank test). CONCLUSION: The arrival to access time and ISS were significantly associated with mortality in the REBOA patients in Japan. The early access group demonstrated better survival. The proactive early access in the resuscitation phase might be related to better patient outcomes. LEVEL OF EVIDENCE: Therapeutic/care management, level V.

RESUMO

Gastric aspiration is the major cause of acute lung injury (ALI) and acute respiratory distress syndrome. Aspiration-induced ALI is believed to be, at least in part, facilitated by neutrophil-derived mediators and toxic molecules. We conducted a prospective cohort study based on the hypothesis that sivelestat, a specific neutrophil elastase inhibitor, is effective for treating ALI following gastric aspiration. Forty-four ALI patients who showed evidence of aspiration were observed within 12 h before intensive care unit admission and who had been mechanically ventilated within 12 h after admission were included in this study. Lung injury score (LIS) and PAO2/FiO2 (P/F) ratio on day 7 were defined as the primary outcomes of the study. Twenty-three patients were assigned to the sivelestat group and 21 to the control group. In univariate analyses, the proportions of patients with LIS lower than 1.0 on day 7 and a P/F greater than 300 on day 7 were significantly higher in the sivelestat group than in the control group (60.9% vs. 26.3%, P = 0.03; 87.0% vs. 36.8%, P = 0.001). In the logistic regression model, the use of sivelestat was an independent predictor for LIS lower than 1.0 on day 7 (relative risk, 7.4; 95% confidence interval [CI], 1.51-36.48) and for a P/F ratio higher than 300 on day 7 (relative risk, 18.5; 95% CI, 2.72-126.46). In the Cox proportional hazards model, the use of sivelestat was associated with a lower cumulative proportion of patients who received mechanical ventilation during the initial 14 days (hazard ratio, 2.6; 95% CI, 1.17-5.55).

RESUMO

Eosinophilia and tissue infiltration by eosinophils are frequent findings in Hodgkin lymphoma, but they are extremely rare in B-cell lymphoma. Reported herein is a case of follicular lymphoma with extensive lymph node infiltration by eosinophils. The patient was a 71-year-old woman who had a mass in the vicinity of the pancreas found on routine ultrasonography. Subsequent CT indicated several enlarged abdominal lymph nodes, although superficial lymph nodes were not palpable. Two swollen mesenteric lymph nodes were excised to determine the cause of the lymphadenopathy. Histology indicated extensive infiltration of numerous eosinophils to the interfollicular area, especially in the dilated sinuses. The lymphoid follicles were relatively small, had inconspicuous germinal centers, and were scattered between dilated sinuses. Based on the histology, immunohistochemistry, and chromosomal abnormality, a diagnosis of follicular lymphoma was made. Expression of interleukin-3 (IL-3), IL-5, eotaxin, eotaxin-2, and eotaxin-3 was investigated on reverse transcription-polymerase chain reaction of the lymph node tissue, but none of the mRNA expression levels were elevated. This was a unique case of follicular lymphoma with extensive eosinophil infiltration, and to the best of the authors' knowledge this is the first such case ever reported.
