  and are pathogenic free-living amoebae that infect the central nervous system with over 95% mortality rates. Although several compounds have shown promise in vitro but associated side effects and/or prolonged approval processes for clinical applications have led to limited success. To overcome this, drug repurposing of marketed compounds with known mechanism of action is considered a viable approach that has potential to expedite discovery and application of anti-amoebic compounds.

3D Interfacial and Spatiotemporal Regulation of Human Neuroepithelial Organoids.

Adv Sci (Weinh) 2022 Jun 6:e2201106. Epub 2022 Jun 6.

Department of Biomedical Engineering, Eindhoven University of Technology, PO Box 513, Eindhoven, 5600 MB, The Netherlands.

Neuroepithelial (NE) organoids with dorsal-ventral patterning provide a useful three-dimensional (3D) in vitro model to interrogate neural tube formation during early development of the central nervous system. Understanding the fundamental processes behind the cellular self-organization in NE organoids holds the key to the engineering of organoids with higher, more in vivo-like complexity. However, little is known about the cellular regulation driving the NE development, especially in the presence of interfacial cues from the microenvironment. Read More

Diagnosis and management of pediatric papillary craniopharyngioma.

World Neurosurg 2022 May 31. Epub 2022 May 31.

Department of Neurosurgery, Sanbo Brain Hospital, Capital Medical University, Beijing, China. Electronic address:

Objective: Papillary craniopharyngioma (PCP) was previously thought to occur only in adults. Sporadic pediatric PCP (PPCP) confirmed by detection of BRAF V600E mutation has been reported since 2018, but is often misdiagnosed before being diagnosed definitively. We aimed to evaluate PPCP characteristics and propose diagnostic criteria for prompt diagnosis, seeking to reduce patient morbidity and mortality and reduce costs linked to misdiagnosis. Read More

DNA methylation profiling of central nervous system hemangioblastomas identifies two distinct subgroups.

Brain Pathol 2022 May 30:e13083. Epub 2022 May 30.

Institute of Neuropathology, University Hospital Münster, Münster, Germany.

Hemangioblastomas (HBs) of the central nervous system are highly vascular neoplasms that occur sporadically or as a manifestation of von Hippel-Lindau (VHL) disease. Despite their benign nature, HBs are clinically heterogeneous and can be associated with significant morbidity due to mass effects of peritumoral cysts or tumor progression. Underlying molecular factors involved in HB tumor biology remain elusive. Read More

GPR37 Receptors and Megalencephalic Leukoencephalopathy with Subcortical Cysts.

Int J Mol Sci 2022 May 16;23(10). Epub 2022 May 16.

Unitat de Fisiologia, Departament de Ciències Fisiològiques, Genes Disease and Therapy Program IDIBELL-Institute of Neurosciences, Universitat de Barcelona, L'Hospitalet de Llobregat, 08907 Barcelona, Spain.

Megalencephalic leukoencephalopathy with subcortical cysts (MLC) is a rare type of vacuolating leukodystrophy (white matter disorder), which is mainly caused by defects in MLC1 or glial cell adhesion molecule (GlialCAM) proteins. In addition, autoantibodies to GlialCAM are involved in the pathology of multiple sclerosis. and genes encode for membrane proteins of unknown function, which has been linked to the regulation of different ion channels and transporters, such as the chloride channel VRAC (volume regulated anion channel), ClC-2 (chloride channel 2), and connexin 43 or the Na/K-ATPase pump.

Pulsating Spinal Arachnoid Cyst as a Hidden Aggravating Factor for Thoracic Spondylotic Myelopathy: A Report of 3 Cases.

JBJS Case Connect 2022 04 1;12(2). Epub 2022 Apr 1.

Department of Orthopaedic Surgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, Sapporo, Japan.

Case: We report 3 cases of thoracic myelopathy caused by vertebral osteophytes and coexisting intradural spinal arachnoid cyst (SAC), which was difficult to diagnose on preoperative magnetic resonance imaging. Intraoperative ultrasound sonography revealed spinal cord impingement because of osteophytes and a pulsating intradural SAC. Repeated pincer compression on the spinal cord seemed to be associated with their paraparetic symptoms. Read More

CystiHuman: A model of human neurocysticercosis.

PLoS Comput Biol 2022 05 19;18(5):e1010118. Epub 2022 May 19.

Center for Global Health Tumbes, Universidad Peruana Cayetano Heredia, Lima, Peru.

Introduction: The Taenia solium tapeworm is responsible for cysticercosis, a neglected tropical disease presenting as larvae in the body of a host following taenia egg ingestion. Neurocysticercosis (NCC), the name of the disease when it affects the human central nervous system, is a major cause of epilepsy in developing countries, and can also cause intracranial hypertension, hydrocephalus and death. Simulation models can help identify the most cost-effective interventions before their implementation. Read More

Case Report: Recurrence of an Extradural Spinal Epidermoid Cyst Following Surgical Excision in a Dog.

Front Vet Sci 2022 15;9:871023. Epub 2022 Apr 15.

Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Purdue University, West Lafayette, IN, United States.

Congenital epidermoid cysts are slow-growing, mass lesions caused by the abnormal inclusion of neuroectodermal tissue within the developing central nervous system. Subtotal excision of epidermoid cysts increases the risk of early recurrence of clinical signs. A 4-year-old female spayed boxer was presented with a 4-month history of ambulatory paraparesis and proprioceptive ataxia. Read More

Pineal morphology of the clinical high-risk state for psychosis and different psychotic disorders.

Schizophr Res 2022 Jun 26;244:1-7. Epub 2022 Apr 26.

Melbourne Neuropsychiatry Centre, Department of Psychiatry, The University of Melbourne and Melbourne Health, Carlton South, Victoria, Australia; Florey Institute of Neuroscience and Mental Health, Parkville, Victoria, Australia; North Western Mental Health, Western Hospital Sunshine, St. Albans, Victoria, Australia.

Background: Pineal volume reductions have been reported in schizophrenia and clinical high-risk states for the development of psychosis, supporting the role of melatonin dysregulation in the pathophysiology of psychosis. However, it remains unclear whether pineal volume is associated with the later onset of psychosis in individuals at clinical high-risk (CHR) of psychosis or if pineal atrophy is specific to schizophrenia among different psychotic disorders.

Methods: This magnetic resonance imaging study examined the volume of and cyst prevalence in the pineal gland in 135 individuals at CHR of psychosis [52 (38. Read More

Megalencephalic leukoencephalopathy with subcortical cysts: the importance of early diagnosis.

Bol Med Hosp Infant Mex 2022 ;79(2):129-134

Departamento de Genética, Escuela de Medicina, Universidad Cuauhtémoc. San Luis Potosí, San Luis Potosí, México.

Background: Megalencephalic leukoencephalopathy with subcortical cysts is a rare type of leukodystrophy associated with mutations in the MLC1 and GlialCAM genes. The classic form is characterized by macrocephaly, early or delayed normal neurodevelopment followed by a period of slow motor skill loss, with cerebellar ataxia and spasticity; some patients develop movement disorders and seizures. Magnetic resonance imaging shows widespread diffuse white matter involvement with edema and subcortical cysts. Read More
