RESUMEN
Surgical treatment for chronic subdural hematomaï¼CSDHï¼has contributed to good outcome. However, several recent studies have revealed that surgical outcomes for elderly patients were not decisively good. In this study, prognosis of CSDH patients in elderly were analyzed. This study included 232 CSDH patients who were treated in our department and 2 affiliated hospitals, and poor prognosis was defined as aggravation of modified Rankin scale (mRS) at examination comparing with that at discharge, or mRS 3 and higher at examination. We collected data from medical records and questionnaires on the following clinical characteristics of patients: age, sex, findings at admission, medication of antiplatelets and anticoagulants, radiological findings on computed tomography, recurrence, place of discharge, perioperative systemic complications, and mRS at discharge and at examination. The cut-off value of age for poor prognosis of all CSDH patients was 74 years old in this study. In multivariate analysis of all cases, age was prognostic factor for poor outcome:75 years old or higherï¼p=0.0002ï¼. In this group, mRS at discharge(p=0.0184) and postoperative medical diseases(p<0.0001) were the risk factors of poor prognosis. In this present study, high age and activities of daily lifeï¼ADLï¼ at discharge were significant prognostic factors for poor outcome of CSDH. Improvement of ADL at discharge with care for postoperative systemic complications and careful rehabilitation can contribute to good prognosis for CSDH in elderly patients.

BACKGROUND: Langerhans cell histiocytosis (LCH) was previously characterized as the proliferation of Langerhans-type histiocytes with a wide range of clinical presentations that arise mostly in children. The typical presentation is a gradually enlarging, painless skull mass. Rapid clinical deterioration is rare. OBSERVATIONS: A 3-year-old boy who had incurred a right frontal impact head injury demonstrated no apparent neurological deficits. He subsequently bruised the same region multiple times. The right frontal swelling gradually increased over the course of 6 days after the initial injury. Skull radiography showed no bony lesion. The same site enlarged markedly 12 days after the initial injury. Magnetic resonance imaging revealed a frontal bony tumorous lesion associated with multiple subcutaneous cystic mass lesions. The patient underwent open biopsy of the skull lesion and evacuation of the subcutaneous lesions. Histopathological examination confirmed the diagnosis of LCH. Immunohistochemical evaluation revealed positivity for CD1a and langerin and no immunopositivity for BRAF V600E. The skull lesion spontaneously disappeared 30 days after the biopsy without recurrence. LESSONS: Physicians should be aware of this rare clinical manifestation of LCH that developed by a repeat head injury.
RESUMEN
Chronic subdural hematoma (CSH) is predominantly a disease of the elderly. Aging societies in advanced countries are seeing the number of CSH cases increasing. We applied a three-day hospitalization protocol for CSH surgery to reduce healthcare costs and more efficiently manage hospital beds. We investigated the clinical factors that influenced prolonged hospitalization. From January 2015 to December 2020, we performed irrigation, evacuation, and drainage of CSH cases in 221 consecutive patients. The χ2 test and logistic regression analysis were conducted to detect clinical factors influencing prolonged hospitalization. A p-value below 0.05 was considered statistically significant. Applying a three-day hospitalization protocol showed no adverse outcomes. Fifty-two (24%) of 221 patients experienced prolonged hospitalization. The χ2 test showed that female gender, atrial fibrillation, alcohol abuse, preoperative consciousness level, verbal function disturbance, and perioperative activities of daily living were significantly related to prolonged hospitalization. Female gender, atrial fibrillation, and alcohol abuse were significant factors in the logistic regression analysis. A three-day hospitalization protocol for CSH is suitable for patient care; however, particular attention needs to be focused on the female gender, atrial fibrillation, and alcohol abuse, all three of which prolong hospitalization.

OBJECTIVE: Some aneurysmal subarachnoid hemorrhage (SAH) patients are delayed in their presentation. This can cause a washout of the subarachnoid hematoma and a potential misdiagnosis. As a result, they may suffer rerupture of the aneurysm and preventable deterioration. We investigated the factors that influence delayed SAH presentation. METHODS: Aneurysmal SAH patients treated at 9 stroke centers from 2002 to 2020 were included. Age, gender, pre-SAH modified Rankin scale, World Federation of Neurological Surgeons grade, Fisher group, day of presentation, aneurysm treatment method, past history of cerebral stroke, comorbidity of hypertension and/or diabetes mellitus, and modified Rankin scaleat discharge were assessed retrospectively. We formed 2 groups based on the day of presentation after the onset of SAH: day 0-3 (early) and other (delayed). Logistic regression analyses detected the factors that influenced the day of presentation and outcome for SAH. A P- value <0.05 was considered significant. RESULTS: Delayed presentation comprised 282 cases (6.3%) of 4507 included cases. Logistic regression analyses showed that patients in an urban area, of male gender, low WFNS grade and low Fisher group correlated significantly with a delayed presentation. But delayed presentation did not influence outcome at discharge. CONCLUSIONS: Area of residency and gender correlated with delayed presentation after SAH in Japan. Urbanization, male gender, and mild SAH lead patients to delay presentation. The factors underlying these tendencies will be analyzed in a future prospective study.

BACKGROUND: Mycobacterium avium complex (MAC) generally causes localized pulmonary infections in immunocompromised hosts, but rarely in other organs and tissues, which is called disseminated MAC infection. OBSERVATIONS: The authors herein present a 48-year-old male patient with disseminated MAC infectious lesions in the lungs and on the cranial, vertebral, femoral, and pelvic bones, a normal CD4 count, and immunopositivity for the interferon-ɤ (IFN-ɤ) neutralization antibody. Cranial lesions were multiple osteolytic lesions associated with abscesses in the cranial bones. The patient initially received conservative treatment with multiple antibiotics; however, cranial lesions worsened. Therefore, multiple cranial lesions were removed via osteoplastic craniectomy and the postoperative course was uneventful. Pathological findings revealed MAC infection. The patient was discharged without recurrence or complications. LESSONS: Multiple cranial MAC dissemination with immunopositivity for the IFN-ɤ antibody is rare. The authors herein present the clinical course of a rare surgical case of MAC dissemination with a literature review.
RESUMEN
Chronic subdural hematoma (CSDH) typically develops in the supratentorial region in elderly patients. We treated a case of unilateral supratentorial and bilateral infratentorial CSDH, whereby the patient had a coronavirus disease 2019 (COVID-19) infection combined with disseminated intravascular coagulation 2 months earlier. The patient had not experienced any head trauma before the onset of the CSDH. The postoperative course was uneventful, and the patient experienced no neurological deficit. We propose that we should be aware not only of acute ischemic or hemorrhagic diseases after COVID-19 infection but also of chronic subdural hematoma caused by coagulopathy after a COVID-19 infection.
RESUMEN
Objective: The recurrence rate of coiled ruptured cerebral aneurysms is greater than that of clipped aneurysms. The aim of this study is to determine the factors that relate to the recurrence of embolized, ruptured cerebral aneurysms, and the evidence thereto. Methods: From April 2007 through July 2017, we treated 134 ruptured cerebral aneurysm cases by coiling. DSA and/or MRI were done in 98 saccular aneurysm cases one year after the coiling. Recurrence was defined as enlargement of the aneurysm neck or contrast opacification along the aneurysm wall. A chi-square test and a logistic regression analysis were done to analyze the relationship between aneurysm recurrence and clinical factors. Results: The median follow-up period was 58 months (interquartile range [IQR]: 33-107). Ten cases (10.2%) were subjected to aneurysm recurrence. Internal carotid artery (ICA) aneurysms proximal to the posterior communicating artery, incomplete obliteration of an aneurysm at initial embolization and postoperative DSA during day 9 ± 2, and increased contrast medium in the aneurysm at postoperative DSA during day 9 ± 2 were all statistically related to the recurrence of the aneurysm. Logistic regression analysis showed that the increased contrast medium in the aneurysm at day 9 ± 2 was statistically related to aneurysm recurrence (p <0.0001). Recurrence or retreatment of the aneurysm did not influence the outcome. Conclusion: Complete obliteration of the aneurysm at the first session is important. Recurrence of an embolized ruptured aneurysm can be estimated by postoperative DSA at day 9 ± 2 days.
RESUMEN
Pathophysiological findings of early brain injury in humans have not permitted conclusive determinations. We explored the essence of this phenomenon by taking intraoperative cortical specimens of Hunt-Kosnik grades IV~V (poor-grade) subarachnoid hemorrhages (SAH). From 2013 to 2017, we treated 39 consecutive poor-grade patients in 226 cases of aneurysmal SAH. Fourteen of the 39 patients agreed to this study following written informed consent. We took specimens from untouched areas prior to surgical intervention: cortex near the ruptured aneurysm for clipping, convexity cortex for cerebral ventricular drainage. Cortical specimens were stained with hematoxylin-eosin, anti-cleaved caspase-3, and anti-DNA/RNA damage staining. Positive signals were calculated in six random, high-power fields for quantitative assessment. Double immunofluorescence was done to evaluate neural damage. Chi-square analyses were carried out to assess the correlation between the Glasgow Outcome Scale at 90 days after the ictus and the number of positive cells. Cortical specimens were taken at 12.7 ± 7.00 h after the first ictus. All 14 cases showed dense nuclei, with the appearance of acidic and shrunken cytoplasms. Diffuse positivity of anti-cleaved caspase-3 and anti-DNA/RNA damage was detected. Cleaved caspase-3 was detected in 68% of neurons, and DNA/RNA damage was detected in 64% of neurons. Positive reactions of both antibodies indicated poor outcome. With poor-grade cases, irreversible ischemic, apoptotic, and oxidative changes were detected in the cerebral cortex within several hours after the ictus. Those changes occurred far from the aneurysm. Our findings suggest that a revolution is needed in the treatment strategy for poor-grade SAH.

Oxidative stress influences many kinds of diseases. Our hypothesis is that oxidative stress and antioxidant potentials correlate with cognitive function, activities of daily life and white matter injury. (UMIN-CTR R000016770) Thirty-two consecutive patients participated to this study after informed consent. A routine biochemical analysis, modified-Rankin Scale (m-RS), revised Hasegawa Dementia Scale (HDS-R), Mini-Mental State Examination (MMSE) and fluid-attenuated-inversion-recovery imaging (FLAIR) were performed before admission. Derivatives of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) were measured photometrically using arterial blood. Statistical analyses were done by analysis variance or logistic regression analysis. Median age was 72 (IQR: 64.3 -- 75.8). The d-ROMS were 367 ± 55.4, and BAP was 1967 ± 284. HDS-R and m-RS deteriorated with d-ROMs elevation (p < 0.05). Uric acid and creatinine decreased with d-ROMs elevation (p < 0.05). Both periventricular hyperintensity grade and deep and subcortical white matter hyperintensity grade worsened with BAP reduction (p < 0.05). Oxidative stress correlates negatively with cognitive function and activities of daily life. Low antioxidative potentials correlate with aggravation of white matter injury. We should control both oxidative stress and antioxidative potential to maintain healthy lives.

BACKGROUND: The most uncontrollable complication during coil embolization of a ruptured cerebral aneurysm is thromboembolic ischemia. We analyzed whether thromboembolic complications could be reduced by using preoperative antiplatelet medications for acute subarachnoid hemorrhage in multicenter fashion. METHODS: We selected antiplatelet medicines according to an official protocol: a combination of 200 mg aspirin, 150 or 300 mg clopidogrel, and 200 mg cilostazol. Systemic heparinization was done after sheath insertion in all cases. One hundred and ten consecutive, ruptured cerebral saccular aneurysms that underwent coiling at our institute were analyzed. Procedure-related thrombus formation on digital subtraction angiography and clinical evidence of ischemia and procedure-related stroke on computed tomography scan were reviewed. RESULTS: Eighty cases (73%) were medicated with multiple antiplatelet medications, 22 cases (20%) were treated with a single medication, and 8 cases (7%) were treated without antiplatelet medication. Thromboembolic complications were reduced in an inverse relationship with the number of antiplatelet medications. Hemorrhagic complications because of antiplatelet medications did not occur. Postoperative symptomatic vasospasm tended to decrease, and outcome also tended to improve in the multiple medications groups. Reduction of thromboembolic complications significantly improved clinical outcome in logistic regression analysis. CONCLUSIONS: Preoperative multiple antiplatelet medication reduced thromboembolic events in coiling during acute stage subarachnoid hemorrhage and improved clinical outcomes.

BACKGROUND AND PURPOSE: Carotid plaque contains biologically active substances released into the blood during carotid artery stenting (CAS). The main purpose of this prospective study was to analyse sequential changes in oxidative stress during CAS and their relationship to clinical factors. METHODS: Twenty-two consecutive CAS procedures were performed between May 2014 and April 2016. Arterial blood was collected four times: (1) after the sheath insertion without edaravone; (2) pre-angioplasty with edaravone from the carotid artery; (3) after post-stenting angioplasty from an occluded carotid artery; and (4) before sheath removal. Derivatives of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) were measured photometrically. The relationship between d-ROMs or BAP and preoperatively investigated biochemical parameters, cognitive function, and number of diffusion-weighted image (DWI) high spot lesions was analysed using one-way ANOVA and the Tukey-Kramer HSD test. RESULTS: The d-ROM values for CAS were 355±58.8 Carratelli Units at sheath insertion, 315±57.2 after edaravone infusion, 328±56.8 after post-stenting angioplasty, and 315±53.0 just before sheath removal. The d-ROM values were reduced significantly after edaravone infusion (P<0.05). The BAP at sheath insertion was reduced significantly according to age (P<0.05). The d-ROMs at sheath insertion correlated negatively with the dementia scale and positively with the post-CAS DWI high spots (1.00±1.07; P<0.05). Other biochemical parameters did not correlate with the d-ROM values or BAP. CONCLUSION: Oxidative stress is correlated negatively with cognitive function and positively with postoperative ischemic lesions. Antioxidant potential decreases with ageing.

Stroke remains a major cause of disability throughout the world: paralysis, cognitive impairment, aphasia, and so on. Surgical or medical intervention is curative in only a small number of cases. Nearly all stroke cases require rehabilitation. Neurorehabilitation generally improves patient outcome, but it sometimes has no effect or even a mal-influence. The aim of this review is the clarification of the mechanisms of neurorehabilitation. We systematically reviewed recently published articles on neural network remodeling, especially from 2014 to 2016. Finally, we summarize progress in neurorehabilitation and discuss future prospects.
