Exclusive Cerebellar and Leptomeningeal Metastases from Early Gastric Cancer 14 Months after Proximal Gastrectomy: An Autopsy Case Report.

NMC Case Rep J 2019 Apr 21;6(2):65-70. Epub 2019 Mar 21.

Department of Neurosurgery, Fukushima Medical University, Fukushima, Fukushima, Japan.

We report a rare autopsy case in which the patient received gastrectomy after an endoscopic diagnosis of early gastric cancer, and had deteriorated due to exclusive metastatic cerebellar tumors identified 14 months after surgery. A 65-year-old male was diagnosed as having a 0-IIc-type early gastric cancer on the posterior wall of the upper stomach by gastrointestinal endoscopy in search of a cause of epigastralgia, and thus received proximal gastrectomy and pyloroplasty. Although the tumor was in the early stages and limited within the mucosal layer, adjuvant chemotherapy was started by using S-1 80 mg daily due to evidence of metastasis into lymph node #3 at the lesser curvature.

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

Overlap of polymicrogyria, hydrocephalus, and Joubert syndrome in a family with novel truncating mutations in ADGRG1/GPR56 and KIAA0556.

Neurogenetics 2019 May 13;20(2):91-98. Epub 2019 Apr 13.

Institute for Neuroscience, Department of Pharmacology and Physiology, The George Washington University School of Medicine and Health Sciences, Washington, 20037, DC, USA.

Genetic mutations associated with brain malformations can lead to a spectrum of severity and it is often difficult to determine whether there are additional pathogenic variants contributing to the phenotype. Here, we present a family affected by a severe brain malformation including bilateral polymicrogyria, hydrocephalus, patchy white matter signal changes, and cerebellar and pontine hypoplasia with elongated cerebellar peduncles leading to the molar tooth sign. While the malformation is reminiscent of bilateral frontoparietal polymicrogyria (BFPP), the phenotype is more severe than previously reported and also includes features of Joubert syndrome (JBTS).

In view of the great need for efficacious therapies for high grade SAH, recent animal studies have demonstrated improved outcomes with administration of mesenchymal stem cells (MSCs) as a potential neuroregenerative strategy. We present the first case of human intravenous administration of MSCs after aneurysmal subarachnoid haemorrhage. Read More

Dynamics of extracellular matrix proteins in cerebrospinal fluid and serum and their relation to clinical outcome in human traumatic brain injury.

Clin Chem Lab Med 2019 Apr 15. Epub 2019 Apr 15.

Department of Psychiatry and Neurochemistry, Institute of Neuroscience and Physiology, Sahlgrenska Academy at the University of Gothenburg, Gothenburg, Sweden.

Background Brevican, neurocan, tenascin-C and tenascin-R are extracellular matrix proteins present in brain that show increased expression in experimental animal models of brain injury. However, little is known about the dynamics of these proteins in human body fluids, such as cerebrospinal fluid (CSF) and serum, after traumatic brain injury (TBI). The aims of this study were to investigate if matrix proteins in CSF and serum are associated with functional outcome following traumatic brain injury, if their concentrations change over time and to compare their levels between brain injured patients to controls.

Increased Water Content in Periventricular Caps in Patients without Acute Hydrocephalus.

AJNR Am J Neuroradiol 2019 Apr 11. Epub 2019 Apr 11.

From the Departments of Diagnostic and Interventional Neuroradiology (T.S., J.K.F., S.D., G.G., M.W., O.N.).

Background And Purpose: Periventricular caps are a common finding on MR imaging and are believed to reflect focally increased interstitial water content due to dysfunctional transependymal transportation rather than ischemic-gliotic changes. We compared the quantitative water content of periventricular caps and microvascular white matter lesions, hypothesizing that periventricular caps associated with increased interstitial fluid content display higher water content than white matter lesions and are therefore differentiable from microvascular white matter lesions by measurement of the water content.

Materials And Methods: In a prospective study, we compared the water content of periventricular caps and white matter lesions in 50 patients using a quantitative multiple-echo, gradient-echo MR imaging water-mapping sequence. Read More

Electronic address:

Tripartite motif 71 (Trim71)/lineage defective 41 (lin-41) is the primary target of the ancient lethal 7 (let-7) miRNA that is essential for survival and development across animal phylogeny. Recent work identified Trim71 as a critical regulator of mammalian neural stem cell (NSC) fate and a bona fide human disease gene in congenital hydrocephalus (CH). Studying TRIM71 as a paradigm of NSC involvement in CH is a remarkable opportunity to better understand the mechanisms that regulate the timing of brain development and the pathogenesis of the most common pediatric neurosurgical disorder.

Cerebrospinal fluid dynamics and intracranial pressure elevation in neurological diseases.

Fluids Barriers CNS 2019 Apr 10;16(1). Epub 2019 Apr 10.

Brain Barriers Group, School of Biomedical Sciences and Pharmacy, The University of Newcastle, Medical Sciences Building, University Drive, Callaghan, NSW, 2308, Australia.

The fine balance between the secretion, composition, volume and turnover of cerebrospinal fluid (CSF) is strictly regulated. However, during certain neurological diseases, this balance can be disrupted. A significant disruption to the normal CSF circulation can be life threatening, leading to increased intracranial pressure (ICP), and is implicated in hydrocephalus, idiopathic intracranial hypertension, brain trauma, brain tumours and stroke.

An update on the central nervous system manifestations of neurofibromatosis type 1.

Acta Neuropathol 2019 Apr 8. Epub 2019 Apr 8.

Department of Pathology, Johns Hopkins University School of Medicine, Sheikh Zayed Tower, Room M2101, 1800 Orleans Street, Baltimore, MD, 21231, USA.

Neurofibromatosis 1 (NF1) is an autosomal dominant genetic disorder that presents with variable phenotypes as a result of mutations in the neurofibromatosis type 1 (NF1) gene and subsequently, abnormal function of the protein product, neurofibromin. Patients with NF1 are at increased risk for central nervous system (CNS) manifestations including structural, functional, and neoplastic disease. The mechanisms underlying the varied manifestations of NF1 are incompletely understood, but the loss of functional neurofibromin, resulting in sustained activation of the oncoprotein RAS, is responsible for tumorigenesis throughout the body, including the CNS.
