RESUMO
OBJECTIVE: Rebleeding of aneurysmal subarachnoid hemorrhage (aSAH) is one of the significant risk factors for poor clinical outcome. The rebleeding risk is the highest during the acute phase with an approximate rebleeding rate of 9-17% within the first 24 h. Theoretically, general anesthesia can stabilize a patient's vital signs; however, its effectiveness as initial management for preventing post-aSAH rebleeding remains unclear. The purpose of this study was to determine the feasibility and safety of ultra-early general anesthesia induction for reducing the rebleeding rates among patients with aSAH. MATERIALS AND METHODS: We retrospectively evaluated patients with aSAH who were admitted to our department between January 2013 and December 2019. All the patients underwent ultra-early general anesthesia induction as initial management regardless of their severity. We evaluated the rebleeding rate before definitive treatment, factors influencing rebleeding, and general anesthesia complications. RESULTS: We included 191 patients with two-third of them having a poor clinical grade (World Federation of Neurological Society [WFNS] grade IV or V). The median duration from admission to general anesthesia induction was 22 min. Rebleeding before definitive treatment occurred in nine patients (4.7%). There were significant differences in the Glasgow Coma Scale score (p = 0.047), WFNS grade (p = 0.02), and dissecting aneurysm (p <0.001) between the rebleeding and non-rebleeding patients. There were no cases of unsuccessful tracheal intubation or rebleeding during general anesthesia induction. CONCLUSION: Ultra-early general anesthesia induction could be performed safely in patients with aSAH, regardless of the WFNS grade; moreover, it resulted in lower rebleeding rate than that reported in previous epidemiological reports.

Purpose: Among mild traumatic brain injuries (mTBI; a Glasgow Coma Scale score ≥13 on arrival), few result in severe neurological deficit, especially when they needed neurosurgical intervention. We investigated the association of intracranial pressure (ICP) control management with neurological outcome in patients with mTBI who needed neurosurgical intervention. Methods: From 1,092 records of the Japan Neurotrauma Data Bank during 2009-2011, we retrospectively identified 195 patients with neurosurgical intervention for mTBI. Using the Glasgow Outcome Scale, we grouped records into two: favorable and poor outcome. We analyzed neurological outcomes using a logistic regression analysis adjusted for ICP control managements. Results: Seventy patients had a poor outcome. Logistic regression analysis revealed that sedatives, hyperosmotic agents, and hyperventilation therapy were significantly associated with poor outcome (odds ratio [OR]: 2.36, 95% confidence interval [CI]: 1.31-4.26; OR: 2.81, 95% CI: 1.17-6.75; OR: 9.36, 95% CI: 1.81-48.35). However, temperature management was significantly related with favorable outcome (OR: 0.26, 95% CI: 0.10-0.66). Conclusions: Our study, using a Japanese multicenter brain trauma registry, suggested that requirement of sedatives, hyperosmotic agents, and hyperventilation is associated with poor neurological outcome for patients with mTBI who underwent neurosurgical intervention, although temperature management was associated with favorable neurological outcome.

BACKGROUND: In the intensive care unit (ICU), multiple intravenous drugs are often administered through the same catheter line, greatly increasing the risk of drug incompatibility. We previously developed a compatibility chart including 27 drugs and have used it to avoid drug incompatibilities in the ICU. This retrospective study evaluated the utility of this chart by analyzing prescriptions and incidents of incompatibilities in an ICU. METHODS: We analyzed 257 ICU prescriptions of two or more continuous infusions on the same day during the period between March 2016 and February 2017 and investigated the rate of compliance with the compatibility chart. Drug combinations were classified as "compatible," "tolerable compatible," "incompatible," and "no data." For all combinations, the compliance rate was defined as the ratio of compatible and tolerable compatible combinations. Additionally, using our hospital incident report database, we analyzed 27,117 injections administered in the ICU between March 2016 and February 2017 and investigated incidents related to incompatibility. RESULTS: Three hundred infusion combinations were identified in the prescriptions. The compliance rate was 97% (n = 293). Of the 113 combinations judged to be tolerable compatible, 98% (n = 111) consisted of three or more continuous medications injected through the same intravenous line. Of the two incidents related to incompatibility in the incident report database, the combination "nicardipine and furosemide" was defined as incompatible in the compatibility chart. CONCLUSIONS: The high rate of compliance with the compatibility chart suggested it was useful in preventing drug incompatibility.

BACKGROUND AND IMPORTANCE: Complex pelvic injuries are among the types of trauma with the highest mortality. Treatment strategies should be based on the hemodynamic status, the anatomical type of fracture, and the associated injuries. Combination therapies, including preperitoneal pelvic packing, temporary mechanical stabilization, resuscitative endovascular balloon occlusion of the aorta, and angioembolization, are recommended for pelvic injuries. OBJECTIVE: To investigate the effect of urgent angioembolization alone on severe pelvic injury-associated mortality. DESIGN, SETTINGS, AND PARTICIPANTS: We used the Japan Trauma Data Bank database, a multicenter observational study, to retrospectively identify adult patients with isolated blunt pelvic injuries (Abbreviated Injury Scale [AIS] score: 3-5) from 2004 to 2018. OUTCOME MEASURES AND ANALYSIS: The primary outcome measure was in-hospital mortality. We subdivided patients into two groups, those who underwent urgent angioembolization and non-urgent angioembolization, and compared their mortality rates. We performed multiple imputation and multivariable analyzes to compare the mortality rates between groups after adjusting for known potential confounding factors (age, sex, Glasgow Coma Scale score, systolic blood pressure on hospital arrival, Injury Severity Score, pelvic AIS score, laparotomy, resuscitative endovascular balloon occlusion of the aorta, and external fixation) and for within-hospital clustering using the generalized estimating equation. MAIN RESULTS: We analyzed 4207 of 345,932 trauma patients, of whom 799 underwent urgent angioembolization. The in-hospital mortality rate was significantly higher in the urgent embolization group than in the non-urgent embolization group (7.4 vs. 4.0%; p < 0.01). However, logistic regression analysis revealed that the mortality rates of patients with urgent angioembolization significantly decreased after adjusting for factors independently associated with mortality (odds ratio: 0.60; 95% confidence interval: 0.37-0.96; p = 0.03). CONCLUSION: Urgent angioembolization may be an effective treatment for severe pelvic injury regardless of the pelvic AIS score and the systolic blood pressure on hospital arrival.

The main histopathological features in the cutaneous lesions of Churg-Strauss syndrome (CSS) are dermal leukocytoclastic vasculitis with a variable eosinophilic infiltrate and non-vasculitic tissue eosinophilia with granuloma formation. This wide histopathological spectrum may account for the various skin manifestations of CSS. However, the unique histopathological combination of dermal eosinophilic vasculitis and subcutaneous granulomatous phlebitis accompanied by bulla formation has not been previously described. We report an unusual CSS case showing dermal necrotizing eosinophilic vasculitis and granulomatous phlebitis in purpuric lesions coupled with subepidermal blistering. The blisters showed dermal granulomatous dermatitis and eosinophilia without evidence of vasculitis. Dermal necrotizing eosinophilic vasculitis was characterized by fibrinoid alteration of the vessel wall, a prominent perivascular eosinophilic infiltrate, a few infiltrating histiocytes along the affected vessel wall, and the absence of neutrophilic infiltration. The underlying subcutaneous granulomatous phlebitis was characterized by an angiocentric histiocytic infiltrate surrounded by marked eosinophilic infiltrate. Deposition of cytotoxic proteins and radicals derived from eosinophils in the vessel walls and papillary dermis followed by a secondary granulomatous response may account for the unique clinical and histopathological features in this case.

Coagulation disorder is a major cause of death in sepsis patients. Recently, sepsis-induced coagulopathy (SIC) scoring was developed as a new criterion for coagulopathy-associated sepsis. We aimed to evaluate the accuracy of the SIC score for predicting the prognosis of septic shock. We analyzed data from a multicenter observational study conducted from 2011 to 2013. We grouped the participants into those who did and did not use vasopressors, and compared the in-hospital mortality rates of SIC and non-SIC patients. Patients who needed vasopressors were considered to have septic shock. We performed survival analysis adjusted by factors independently associated with mortality. SIC developed in 66.4% of patients who used vasopressors and 42.2% of patients who did not. The in-hospital mortality difference between the SIC and non-SIC groups was statistically significant in those who needed vasopressors (35.8% vs 27.9%, p < 0.01). Cox regression analysis indicated that SIC was significantly correlated with mortality risk in patients who used vasopressors (hazard ratio [HR] 1.39; 95% confidence interval [CI] 1.13-1.70; p < 0.01), but not in those who did not (HR 1.38; 95% CI 0.81-2.34; p = 0.23). In conclusion, the SIC score might be a good diagnostic indicator of fatal coagulopathy among sepsis patients who need vasopressors.

BACKGROUND: Only a few studies have reported the association between age and mortality in COVID-19 patients who require invasive mechanical ventilation (IMV). We aimed to evaluate the effect of age on COVID-19-related mortality among patients undergoing IMV therapy. METHODS: This cohort study was conducted using the COVID-19 Registry Japan database, a nationwide multi-centre study of hospitalized patients with laboratory-confirmed COVID-19. Of all 33,808 cases registered between 1 January 2020 to 28 February 2021, we analysed 1555 patients who had undergone IMV. We evaluated mortality rates between age groups using multivariable regression analysis after adjusting for known potential components, such as within-hospital clustering, comorbidities, steroid use, medication for COVID-19, and vital signs on admission, using generalized estimation equation. RESULTS: By age group, the mortality rates in the IMV group were 8.6%, 20.7%, 34.9%, 49.7% and 83.3% for patients in their 50s, 60s, 70s, 80s, and 90s, respectively. Multivariable analysis showed that compared with those for patients aged < 60 years, the odds ratios (95% confidence interval) of death were 2.6 (1.6-4.1), 6.9 (4.2-11.3), 13.2 (7.2-24.1), 92.6 (16.7-515.0) for patients in their 60s, 70s, 80s, and 90s, respectively. CONCLUSIONS: In this cohort study, age had a great effect on mortality in COVID-19 patients undergoing IMV, after adjusting for variables independently associated with mortality. This study suggested that age was associated with higher mortality and that preventing progression to severe COVID-19 in elderly patients may be a great public health issue.
RESUMO
We report a case of common mantle cell lymphoma (MCL) with subcutis infiltration and transformation to blastoid MCL in the overlying dermis. The patient was initially diagnosed as having chronic lymphocytic leukemia and treated with chemotherapy. Eight months after the diagnosis of MCL with bone marrow involvement, subcutaneous nodules developed on the patient's left thigh and forearm. A skin biopsy showed a massive infiltration of neoplastic lymphocytes throughout the dermis and subcutaneous tissue. In the upper dermis, there was a perivascular mixed infiltrate of atypical large lymphoid cells and small-sized cells. In the mid to lower dermis, the infiltrate was dense with a nodular growth pattern and was composed of atypical large lymphoblast-like cells with large nuclei, dispersed chromatin, and numerous mitoses. In the subcutaneous tissue, there was a diffuse infiltration of neoplastic cells with common MCL cytologic features characterized by small- to medium-sized lymphoid cells. Cells in the common and blastoid variants of MCL were immunohistochemically positive for CD20 and cyclin D1 but negative for CD5. Neoplastic lymphocytes from the patient's bone marrow had the typical morphologic features and the immunophenotype of MCL (ie, CD5, CD20, cyclin D1, CD10, and CD23). Other case reports in the medical literature indicate that an MCL with skin invasion tends to have a poor prognosis. Our patient died 3 months after the appearance of skin invasion.

BACKGROUND: Little is known regarding functional outcome following poor-grade (World Federation of Neurosurgical Societies grades IV and V) aneurysmal subarachnoid hemorrhage (aSAH), especially in individuals treated aggressively in the early phase after ictus. METHODS: We provided patients with aSAH with ultra-early definitive treatment, coiling or clipping, within 6 hours from arrival as per protocol. We classified the patients into 3 groups according to their computed tomography findings: Group 1, intraventricular hemorrhage with obstructive hydrocephalus; Group 2, massive intracerebral hemorrhage with brain herniation; and Group 3, neither Group 1 nor Group 2. We retrospectively evaluated patients with poor-grade aSAH who were admitted to our department between January 2013 and December 2016. We evaluated functional outcome at 6 months, defining modified Rankin Scale (mRS) scores of 0-2 as good and those of 3-6 as poor outcomes. RESULTS: A good functional outcome was observed in 39.4% (28/71) of all cases. All-cause mortality at 6 months was 15.5% (11/71). A good outcome in Group 3 was significantly higher than that in the other two groups (Group 1 and 2 vs. Group 3, 20.8% vs. 48.9%, p = 0.02), even after adjustment with a multiple logistic regression analysis (odds ratio 6.1, 95% confidence interval 1.1 to 34.8). CONCLUSIONS: Approximately 40% of patients with poor-grade aSAH became functionally independent, and approximately half of the patients with poor-grade aSAH who had neither intraventricular hemorrhage with obstructive hydrocephalus nor with brain herniation had good functional outcomes. Although further trials are required to confirm our results, ultra-early surgery may be considered for patients with poor-grade aSAH.

BACKGROUND: The management of cervical spinal cord injury (SCI) has changed drastically in the last decades, and surgery is the primary treatment. However, the optimum timing of early surgical treatment (within 24 h or 72 h after injury) is still controversial. We sought to determine the optimum timing of surgery for cervical SCI, comparing the length of the intensive care unit (ICU) stay and in-hospital mortality in patients who underwent surgical treatments (decompression and stabilization) for cervical SCI within 24 h after injury and within 7 days after injury. METHODS: This was a retrospective cohort study using Japan Trauma Data Bank (JTDB) which is a nationwide, multicenter database. We selected adult isolated cervical SCI patients who underwent operative management within 7 days after injury, between 2004 and 2015. The main outcome measures were the length of ICU stay and in-hospital mortality. We grouped the patients into two, based on the time from onset of injury to surgery, an early group (within 24 h) and a late group (from 25 h to 7 days). Next, we performed multivariable analyses for analyzing the relevance between the timing of surgery and the length of ICU stay after adjusting for baseline characteristics using propensity score. We also performed the Cox survival analyses to evaluate in-hospital mortality. RESULTS: From 236,698 trauma patients registered in JTDB, we analyzed 514 patients. The early group comprised 291 patients (56.6%), and the late group comprised 223 (43.4%). The length of ICU stay did not differ between the two groups (early, 10 days; late, 11 days; p = 0.29). There was no significant difference for length of ICU stay between the early and late group even after adjustment by multivariate analysis (p = 0.64). There was no significant difference in in-hospital mortality between the two groups (the early group 3.8%, the late group 2.2%, p = 0.32), and no significant difference was found in the Cox survival analysis. CONCLUSIONS: Our study showed that neither the length of ICU stay nor in-hospital mortality after spinal column stabilization or spinal cord decompression for cervical SCI significantly differed according to the timing of surgery between 24 h and 7 days.
