Predictors of endoscopic third ventriculostomy ostomy status in patients who experience failure of endoscopic third ventriculostomy with choroid plexus cauterization.

J Neurosurg Pediatr 2019 Apr 19:1-6. Epub 2019 Apr 19.

1Surgical Outcomes Center for Kids, Monroe Carell Jr. Children's Hospital at Vanderbilt, Nashville.

OBJECTIVEAt failure of endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC), the ETV ostomy may be found to be closed or open. Failure with a closed ostomy may indicate a population that could benefit from evolving techniques to keep the ostomy open and may be candidates for repeat ETV, whereas failure with an open ostomy may be due to persistently abnormal CSF dynamics. This study seeks to identify clinical and radiographic predictors of ostomy status at the time of ETV/CPC failure. Read More

MEK1/2 inhibitor U0126, but not nimodipine, reduces upregulation of cerebrovascular contractile receptors after subarachnoid haemorrhage in rats.

PLoS One 2019 12;14(4):e0215398. Epub 2019 Apr 12.

Department of Clinical Experimental Research, Copenhagen University Hospital, Rigshospitalet-Glostrup, Denmark.

Vascular pathophysiological changes after haemorrhagic stroke, such as phenotypic modulation of the cerebral arteries and cerebral vasospasms, are associated with delayed cerebral ischemia (DCI) and poor outcome. The only currently approved drug treatment shown to reduce the risk of DCI and improve neurologic outcome after aneurysmal subarachnoid haemorrhage (SAH) is nimodipine, a dihydropyridine L-type voltage-gated Ca2+ channel blocker. MEK1/2 mediated transcriptional upregulation of contractile receptors, including endothelin-1 (ET-1) receptors, has previously been shown to be a factor in the pathology of SAH. Read More

A Direct Correlation Between Red Blood Cell Indices and Cognitive Impairment After Aneurysmal Subarachnoid Hemorrhage (aSAH).

Curr Neurovasc Res 2019 Apr 12. Epub 2019 Apr 12.

Department of Neurology, Shanghai Tenth People's Hospital, Tongji University, 301# Middle Yanchang Road, Shanghai 200072. China.

Background/aims: Cognitive impairment can occur after aneurysmal subarachnoid hemorrhage (aSAH) though it commonly tends to be neglected. RBC indices are associated with long-term functional outcomes, while it is unclear whether RBC indices could be a potential predictor of cognitive decline after aSAH. We aimed to investigate the association between RBC indices and post-aSAH cognitive impairment at 1 year. Read More

Meta-analysis of recent literature on utility of follow-up imaging in isolated perimesencephalic hemorrhage.

Clin Neurol Neurosurg 2019 May 11;180:111-116. Epub 2019 Mar 11.

Department of Radiology and Biomedical Imaging, Yale School of Medicine, Box 208042, Tompkins East 2, 333 Cedar St, New Haven, CT, 06520-8042, United States. Electronic address:

Objectives: Isolated perimesencephalic subarachnoid hemorrhage is an uncommon, distinct subtype of subarachnoid hemorrhage with a more benign prognosis. A negative computed tomographic angiogram has been shown to be reliable in excluding aneurysmal rupture as the underlying etiology. However, some studies continue advocating for more imaging to determine a vascular cause in perimesencephalic subarachnoid hemorrhage. Read More

Periodontitis and gingival bleeding associate with intracranial aneurysms and risk of aneurysmal subarachnoid hemorrhage.

Neurosurg Rev 2019 Apr 10. Epub 2019 Apr 10.

Hemorrhagic Brain Pathology Research Group, Kuopio University Hospital, Kuopio, Finland.

Oral bacteria DNA has been found in intracranial aneurysms (IA) and a high prevalence of periodontitis was reported in IA patients. We investigated whether periodontitis associates with IA formation and aneurysmal subarachnoid hemorrhage (aSAH). First, we compared in a case-control setting the prevalence of periodontal disease in IA patients (42 unruptured IA, 34 ruptured IA) and in age- and gender-matched controls (n = 70) from the same geographical area (Health 2000 Survey, BRIF8901).

Neutrophil extracellular traps in the central nervous system hinder bacterial clearance during pneumococcal meningitis.

Nat Commun 2019 04 10;10(1):1667. Epub 2019 Apr 10.

Division of Infection Medicine, Department of Clinical Sciences, Lund University, 22184, Lund, Sweden.

Neutrophils are crucial mediators of host defense that are recruited to the central nervous system (CNS) in large numbers during acute bacterial meningitis caused by Streptococcus pneumoniae. Neutrophils release neutrophil extracellular traps (NETs) during infections to trap and kill bacteria. Intact NETs are fibrous structures composed of decondensed DNA and neutrophil-derived antimicrobial proteins. Read More

[Progress in genetic research on familiar aneurysms].

Zhong Nan Da Xue Xue Bao Yi Xue Ban 2019 Mar;44(3):338-344

Department of Neurosurgery, Xiangya Hospital, Central South University, Changsha 410008, China.

The subarachnoid hemorrhage (SAH) caused by ruptured intracranial aneurysms (IAs) is always a lethality. Increasing evidence suggests a familiar aggregation of IA occurrence, which may relate to genetics and there might be an increasing number of IAs in IA families when mutation of disease genes is aggregating. With the progress in the study of familiar intracranial aneurysms (FIAs), a large number of chromosome fragments are found to be related with IAs, such as 1p36, 5q31, 7q11, 14q22, 17cen, 19q13, Xp22.

The "Brain Stress Timing" phenomenon and other misinterpretations of randomized clinical trial on aneurysmal subarachnoid hemorrhage.

Neural Regen Res 2019 Aug;14(8):1364-1366

Division of Cerebrovascular and Skull Base Neurosurgery, Institute of Neurosurgery Dr Asenjo, Santiago, Chile.

Clipping and coiling are currently the two alternatives in treatment of ruptured cerebral aneurysms. In spite of some meritorious analysis, further discussion is helpful to understand the actual state of art. Retreatment and rebleeding rates clearly favors clipping, although short-term functional outcome seems to be beneficial for clipping, while this different is not such if we perform the comparison at a longer follow up.

Neural Regen Res 2019 Aug;14(8):1309-1312

Department of Vascular and Endovascular Surgery, Heinrich-Heine-University of Düsseldorf, Düsseldorf, Germany.

Erythropoietin (EPO) is one of the most successful biopharmaceuticals in history and is used for treating anemia of different origins. However, it became clear that EPO could also work in a neuroprotective, antiapoptotic, antioxidative, angiogenetic and neurotropic way. It causes stimulation of cells to delay cell apoptosis, especially in the central nervous system. Read More
