الوصف: Listeria monocytogenes is a rare cause of bacterial meningitis, particularly beyond the neonatal period. This article describes a 16-month-old girl who presented with a new-onset febrile status epilepticus, and subsequently developed altered mentality and lethargy. L. monocytogenes was detected on a point-of-care, multiplex polymerase chain reaction using the cerebrospinal fluid. On day 3, she developed a rapidly progressive hydrocephalus. Her consciousness improved after placement of an external ventricular drain. After 3-week antibiotic therapy, she was successfully discharged without residual complications.

الوصف: Background Acute increased intracranial pressure (IICP) is a life-threatening condition that requires urgent treatment. Rapid IICP with hydrocephalus may be complicated by ischemic stroke, convulsions, loss of consciousness, brain herniation, and death. Extremely rare complications include intracranial vessel entrapment and ischemic stroke due to sudden IICP in cases with benign tumors. Case Report We report a case of bilateral posterior cerebral artery region infarction and complicated hydrocephalus with subependymal giant cell astrocytoma in a patient with tuberous sclerosis. Conclusion We postulate that the temporary IICP induced by seizure led to transient bilateral posterior cerebral artery entrapment, causing ischemic stroke without vascular occlusion.

الوصف: Purpose The purpose of this study was to report the authors’ experience with external ventricular drainage (EVD) before endovascular treatment (EVT) in patients with acute aneurysmal subarachnoid hemorrhage (aSAH) and to investigate its relation to hemorrhagic complications.Materials and Methods Between March 2010 and December 2017, a total of 122 patients were recruited who had an aSAH, underwent EVT to secure the ruptured aneurysm, and had EVD performed within 72 hours of rupture. The pre-embo EVD group (n=67) comprised patients who underwent EVD before EVT, and the post-embo EVD group (n=55) comprised those who underwent EVD after EVT. Results Overall, EVD-related hemorrhage occurred in 18 patients (14.8%): six (8.9%) in the pre-embo EVD group and 12 (21.8%) in the post-embo EVD group (P=0.065). No rebleeding occurred between EVD and EVT in the pre-embo EVD group. Clinical outcomes at discharge did not differ significantly between groups (P=0.384). At discharge, the final modified Rankin Scale score in patients who experienced pre-embo rebleeding was better in the pre-embo EVD group than in the post-embo EVD group (P=0.041). Current use of an antiplatelet agent or anticoagulant on admission (odds ratio [OR], 2.928; 95% confidence interval [CI], 1.234–7.439; P=0.042) and stent use (OR, 2.430; 95% CI, 1.524–7.613; P=0.047) remained independent risk factors for EVD-related hemorrhagic complications. Conclusion EVD before EVT in patients with aSAH in acute period did not increase the rate of rebleeding as well as EVD-related hemorrhagic complications. Thus, performing EVD before EVT may be beneficial by normalizing increased intracranial pressure. Especially in patients with rebleeding before the ruptured aneurysm is secured, pre-embo EVD may improve clinical outcomes at discharge.

الوصف: Displacement of distal ventriculo-atrial (VA) shunt is not uncommon. However, misplacement of the distal catheter of VA shunt in the internal jugular vein is a possibility, especially when conducted without intraoperative monitoring. We describe a patient in whom a VA shunt was performed due to failure of ventriculo-peritoneal shunt and the distal catheter of the shunt was found to be misplaced in the left internal jugular vein. Endovascular intervention via femoral vein was used to retrieve the distal catheter.

مستخلص: Dementia is a clinical syndrome that can be caused by multiple conditions, with variable speed of onset, rate of evolution, and duration. Some of these conditions are relentlessly progressive and ultimately fatal, some are treatable, and a few are reversible. Approximately 10% of patients are categorized as having treatable dementias, with normal pressure hydrocephalus (NPH), chronic subdural hematoma, and slow growing brain tumors being the most common etiologies. Idiopathic NPH is a typical treatable form of dementia. The invasive and non-invasive tests of cerebrospinal fluid (CSF) dynamics and drainage can provide an improved measure of postoperative outcomes. However, there is no evidence that testing is superior to clinical examination. Therefore, we should be cautious when excluding patients from shunting based on testing. Two changes in CSF circulatory physiology have been noted as part of ageing. CSF production and turnover are further diminished in patients with Alzheimer's disease (AD) and idiopathic NPH. Poor CSF clearance of proteins, such as Tau and beta amyloid, may play a role in the progression of AD. Improving CSF drainage by shunt can enhance the extracellular clearance of end products of oxidative reactions and lower brain lipid peroxidation. Recently, some efforts for treating AD have been reported. Altering the brain micro-environment to foster appropriate maturation of graft-derived neurons may be critical for improving the efficacy of neural stem cell transplantation therapy for AD. Neuroanatomic circuits mediating memory are accessible and the function of memory circuits can be modulated with neurostimulation, such as deep brain stimulation (DBS) and vagal nerve stimulation. We may identify therapeutic implications for patients with memory disorders. Such studies provide the proof of principle that DBS may remotely activate neocortical structures to enhance memory performance. [ABSTRACT FROM AUTHOR]

مصطلحات موضوعية: Kaolin-induced hydrocephalus, Pressure-volume index, Somatosensory evoked potential, Somatosensory evoked cortical field potential

الوصف: Objective：Somatosensory evoked potential(SSEP) has been known to be a good method for evaluating brain stem function, but it is not sufficient to check the fine changes of cortical functions. A fine change of cortical function can be expressed with somatosensory evoked cortical field potential(SSEFP) rather than general SSEP. To confirm the usefulness of SSEFP for evaluating the cortical function, the authors simultaneously measured SSEFP and the intracranial pressure-volume index(PVI) in kaolin-induced hydrocephalic rats. Method：Hydrocephalus was induced with injection of 0.1ml kaolin-suspended solution into the cisterna magna in 60 Sprague-Dawley rats. The authors measured PVI and SSEFP 1 week after injection of kaolin-suspended solution. To evaluate the severity of induced hydrocephalus, we measured the transverse diameter of the lateral ventricle on the coronal slice of the rat brain 0.40mm posterior to the bregma. Result：The typical wave form of SSEFP in control rats showed a negative-positive complex wave at early latency. In SSEFP of normal rats, N0 is 10.0 msec, N1 15.3 msec, P1 31.2 msec and N1-P1 amplitude 15.4μV. As hydrocephalus progressed, the peak latency of N1 and P1 were delayed. In mild hydrocephalus, negative peak waves were split. The N1-P1 amplitude was decreased only in severe hydrocephalus. The changes of the characteristics of SSEFP according to the severity of hydrocephalus were well correlated with the changes of PVI. Shunting normalized the characteristics of SSEFP in relation to ventricular sizes and PVI in hydrocephalic rats. Conclusion：SSEFP may be useful for evaluating the impairment of cortical function in hydrocephalus. ; open

مصطلحات موضوعية: Objective: To evaluate fetal motor habituation pattern using kinetocardiotocography. Methods: Fifty patients, gestational age above 32 weeks, from May to September 1998 have been studied. Kinetocardiotocography[Model: Hewlett-Packard M1350A 50series] was used with vibroacoustic stimulation of 3 seconds duration with 30 seconds interval for 10 to 51 times. Results: Of the 50 patients, 22 showed normal habituation pattern and the remaining 28 showed abnormal habituation pattern. Concerning the factors which may have influenced the pregnancy outcomes, of the 22 patients who had normal habituation pattern, there were 2 obstetric complications. But of the 28 patients who had abnormal habituation pattern, 15 result in PIH, low birth weight, meconium staining, meningitis, hydrocephalus or heart anomaly. Conclusion: Kinetocardiotocography can be used in observing fetal motor habituation, Kinetocardiotocography, Fetal motor habituation

مصطلحات موضوعية: Experimental hydrocephalus, Ultrastructure of ependyma, Ependymal cell, Periventricular lucency, Junctional complex

الوصف: Morphological changes in the ependymal lining of the hydrocephalic brain included stretching and tearing of the ependyma, thickening and gliosis of the subependymal layer, progressive loss of cilia land microvilli from the ependymal surface, and widening of the extracellular space. In the CT scan of the brain, periventricular low density was one of the common findings in hydrocephalus. The present experiment was performed to investigate not only the ultrastructuralchanges of the ventricular walls in hydrocephalus but also the morphological basis of periventricular lucency detected in the" brain CT scan of the hydrocephalic patients. Hydrocephalus was induced in rats by intracisternal injection of thick kaolin suspension after surgical exposure of atlanto-ocoipital membrane. Lateral wall of the lateral ventricle was examined with ´´transmission electron microscope in 3 different groups(6 rats at 1 week after the hydrocephalus, 8 at 2 weeks, and 4 at 8 weeks). The results were as follows 1) Ultrastructural changes of the ependymal lining in hydrocephalic rat were flattening of ependymal cell and its nucleus, loss of cilia and microvilli from the ependymal surface, widening of the junctional complex, vacuoles and enlargement of cisternal space of rough endoplasmic reticulum in cytoplasm, and thickening and gliosis of subependymal layer. 2) These changes became more severe with longer duration of hydrocephalus. 3) Widening of junctional complex was considered to be the morphological basis for migration of ventricular cerebrospinal fluid into the periventricular white matter with resultant periventricular low density in the CT scan of the brain. ; open

مصطلحات موضوعية: Hydrocephalus, VP shunt, Malfunction, Time course

الوصف: The Ventriculo-peritoneal(VP) shunt is effective and easy method for the treatment of hydrocephalus. But it has a high complication rate including malfunction and infection. This study seeks to find out how to reduce reoperation and complication rates of previously VP shunt-treated patients by analyzing risk factors, complication, and the relationship with the time course. The authors reviewed 714 cases with VP shunt performed from 1986 to 1994. The risk factors of VP shunt related complications were insufficient surgical skill, younger age group, and some causes of -hydrocephalus which were meningitis, neurocysticercosis. and congenital origin. The complications including shunt malfunction were most frequent within -1 month. after the initial VP shunt and were most common at the proximal site of the shunt system. ; open
