Abstract

Aneurysmal subarachnoid hemorrhage (SAH) is a serious clinical event associated with high mortality and, among survivors, serious morbidity. Maintaining the muscle volume in SAH patients is essential, as rehabilitation is often required after intensive care. In this study, we investigated whether proper nutritional administration improved clinical outcomes based on patients laboratory data and level of activities of daily living. This retrospective study was carried out on 250 consecutive SAH patients who underwent craniotomy within 72 hours of onset from February 2005 to June 2018. Finally, 75 patients with a BMI < 22 kg / m2 were included. We compared postoperative energy and protein intake in relation to measures of biochemical parameters and modified Rankin Scale at discharge. Serum Alb concentrations at 25-35 hospital days was significantly improved by postoperative energy intake of ≥ 25 kcal / kg and protein intake of ≥ 0.8 g / kg per day beginning 3 days. High serum Alb concentrations at 25-35 hospital days following the start of this intake were independent factors for good prognosis. This study suggests that the minimum postoperative nutritional intake per day for SAH patients undergoing aneurysmal clipping is 25 kcal / kg of energy and 0.8 g / kg of protein. Higher serum Alb concentrations corresponded to improved long-term functional outcome.

Abstract

Introduction: Streptococcus mutans (SM) with the collagen-binding protein Cnm is a unique member of the oral resident flora because it causes hemorrhagic vascular disorders. In the multicenter study, we examined the relationship between Cnm-positive SM (CP-SM) and intracranial aneurysm (IA) rupture, which remains unknown. Methods: Between May 2013 and June 2018, we collected whole saliva samples from 431 patients with ruptured IAs (RIAs) and 470 patients with unruptured IAs (UIAs). Data were collected on age, sex, smoking and drinking habits, family history of subarachnoid hemorrhage, aneurysm size, number of teeth, and comorbidities of lifestyle disease. Results: There was no difference in the positivity rate of patients with CP-SM between the patients with RIAs (17.2%) and those with UIAs (19.4%). In subanalysis, the rate of positivity for CP-SM was significantly higher in all IAs <5 mm than in those ≥10 mm in diameter (p = 0.0304). In the entire cohort, the rate of positivity for CP-SM was lower in larger aneurysms than in smaller aneurysms (p = 0.0393). Conclusions: CP-SM was not involved in the rupture of UIAs. In the subanalysis, the possibility of its involvement in the formation of vulnerable aneurysms remained. [ABSTRACT FROM AUTHOR]

Abstract

Human papillomavirus (HPV)‐related multiphenotypic sinonasal carcinoma (HMSC) is newly suggested and characterized by HPV‐related tumors. HMSC has a relatively good prognosis. No cases of brain invasion have been reported to date. We encountered a case of brain invasion by HMSC, in which we assessed the effectiveness of radiotherapy in comparison with biopsy and autopsy. A 69‐year‐old man was referred to a hospital three months after intracerebral hemorrhage (ICH). Contrast magnetic resonance imaging revealed a tumor in the ethmoid sinus involving the brain. We performed transnasal biopsy and intensity‐modulated radiotherapy for sinonasal and intracranial lesions. Despite radiotherapy, the patient died on day 41 after radiation. Biopsy specimens displayed mixed findings of epithelial and mesenchymal components. The tumor was immunoreactive for p16, and the RNA in situ hybridization for HPV was positive. Finally, we diagnosed the patient as having HMSC. Autopsy of the sinonasal tissue revealed a reduction in the number of tumor cells. There was a marked reduction in the number of tumor cells in the sinonasal tissue compared to that in the invaded brain tissue. The effectiveness of radiotherapy could depend on the histopathological components and location of the lesion, even in the same patient. [ABSTRACT FROM AUTHOR]

31. Setting pressure can change the size and shape of MRI artifacts caused by adjustable shunt valves: a study of the 4 newest models.

Abstract

Objective: Adjustable shunt valves that have been developed for the management of hydrocephalus all rely on intrinsically magnetic components, and artifacts with these valves on MRI are thus inevitable. The authors have previously reported that the shapes of shunt artifacts differ under different valve pressures with the proGAV 2.0 valve. In the present study the authors compared the size and shape of artifacts at different pressure settings with 4 new-model shunt valves., Methods: The authors attached 4 new models of MRI-resistant shunt valve to the temporal scalp of a healthy volunteer: the proGAV 2.0; Codman Certas Plus; Polaris; and Strata MR. They set 3 different scales of pressures for each valve, depending on magnet orientation to the body axis. Artifacts were evaluated and compared among all valves on a 3.0-T GE scanner and 2 valves were also evaluated on a Philips scanner and a Siemens scanner. In-plane artifact sizes were evaluated as the maximum distance of the artifact from the expected scalp., Results: The sizes and shapes of artifacts changed depending on valve pressure for all valves on the 3 different MRI scanners. Artifacts were less prominent on spin echo sequences than on gradient echo sequences. For diffusion-weighted imaging and time-of-flight MR angiography, the authors matched image numbers within the same sequence and compared appearances of artifacts. For all valves, the number of images affected by artifacts and the image number showing the largest artifact differed among valve settings., Conclusions: Artifacts of all adjustable shunt valves showed gross changes corresponding to pressure setting. Not only the maximum distance of artifacts but also the shape changed significantly. The authors suggest that changing pressure settings offers one of the easiest ways to minimize artifacts on MRI.

Abstract

We present a rare case of an acute epidural hematoma extending through a skull fracture into a cephalohematoma in a neonate. The epidural hematoma was caused by a fall after delivery. The neonate remained neurologically asymptomatic. A computed tomography scan 12 days after delivery showed the large-volume epidural hematoma with midline shift. We performed a strip-bending osteoplastic craniotomy and removed the epidural hematoma and external cephalohematoma under neuroendoscopic control. This is the first reported case of an acute epidural hematoma in a neonate treated successfully neuroendoscopically via a strip-bending craniotomy., (Georg Thieme Verlag KG Stuttgart · New York.)
