#1
Elizabeth A Enninga, Rodrigo Ruano
Fetal lower urinary tract obstruction (LUTO) is a heterogeneous pathology associated with a high morbidity and mortality due to pulmonary hypoplasia. Previously, when a fetus was diagnosed on ultrasound with LUTO, expectant care or termination was the only option; this has changed because of fetal surgical intervention. Vesicoamniotic shunts and cystoscopy are the current methods utilized to treat LUTO; however, it remains difficult to determine whether or not fetal prognosis favors intervention and long term outcome follow up has been limited...

INTRODUCTION: High grade glioma (HGG) treatment has seen a paradigm shift with intensified regimes, but hospitalisation burden is partially attributed to side effects of therapy. Symptomatic communicating hydrocephalus (HC) is a potential complication. Aim of this study was to investigate its incidence, risk factors and treatment in a contemporary cohort. METHODS: We performed a retrospective review of HGG patients. Patients with symptomatic communicating HC were identified and demographic, tumour and treatment variables extracted from hospital notes...

PURPOSE: Shunt placement indications are stringent and require confirmation of clinical and radiological evidence of hydrocephalus (HC). The aim of this study was to determine the rate of shunting and discuss the outcome in the first year of life in patients with myelomeningocele (MMC) on the basis of review of the literature. METHODS: All patients who underwent postnatal repair of MMC at our institution between March 2014 and March 2015 were evaluated. Patients were only included if they underwent both MMC repair and ventriculoperitoneal (VP) shunt insertion at our institution and were followed up for at least 12 months...

The technology of carbon dioxide (CO2) capture and storage (CCS) has provided a new option for mitigating global anthropogenic emissions with unique advantages. However, the potential risk of gas leakage from CO2 sequestration and utilization processes has attracted considerable attention. Moreover, leakage might threaten soil ecosystems and thus cannot be ignored. In this study, a simulation experiment of leakage from CO2 geological storage was designed to investigate the short-term effects of different CO2 leakage concentration (from 400 g m(-2) day(-1) to 2,000 g m(-2) day(-1)) on soil bacterial communities...

BACKGROUND: The generation of velocity-time integrals (VTIs) from Doppler signals is an essential component of standard echocardiographic investigations. The most effective algorithm to compensate for growth in children has, however, not yet been identified. This study was initiated to establish pediatric reference values for VTI and to enhance the interpretability of those values, considering technical and physiological factors. METHODS: The echocardiographic data sets of healthy children and adolescents (N = 349; age range, 0-20 years) were recorded in a prospective approach and subsequently analyzed...

BACKGROUND: Complex hydrocephalus affecting lateral and fourth ventricles separately is occasionally managed with CSF diversion via supra- and infra-tentorial ventricular catheters. The optimal configuration to reduce complications is currently unknown in adults. We describe a consistently similar clinical presentation of patients with complex hydrocephalus and a fourth ventricle separately drained by infra-tentorial shunt insertion. METHODS: A retrospective single centre case series...

BACKGROUND: Entrapment of the temporal horn, known as isolated lateral ventricle (ILV), is a rare type of noncommunicating focal hydrocephalus, and its standard treatment has not been established. Here, we report two cases of endoscopic surgery for ILV, and highlight the anatomical surgical nuances to avoid associated surgical risks. CASE DESCRIPTION: The authors present two surgical cases with ILV treated by endoscopic surgery. The first patient with recurrent ILV, due to shunt malfunction, following the initial shunt placement for ILV...

Surgical management of elevated intraocular pressure (IOP) in an eye with scarred conjunctiva, an encircling band, and silicone oil has limited options. By combining the flow restrictor of the Ahmed Glaucoma Valve (New World Medical, Rancho Cucamonga, California) and the capsule of the encircling band as a conduit for aqueous flow, immediate pressure reduction could theoretically be achieved in eyes with limited conjunctival mobilization. This is a description of a surgical technique in a case of a patient with multiple ocular surgeries with uncontrolled multimechanism glaucoma despite using all available topical and oral glaucoma medications...

A 54-year-old woman with a history of multiple cardiac surgeries suffered from hypoxemia caused by a right-to-left intra-cardiac shunt due to coronary sinus (CS) anomaly with persistent left superior vena cava (PLSVC). Both the contrast echocardiography and enhanced computed tomography (CT) provided conclusive diagnosis of this rare congenital anomaly, which was overlooked for a long time. However, an important diagnostic clue was left-arm injection of the contrast media. In the present case, previously performed enhanced CT with its routine manner, i...

BACKGROUND: The objective was to evaluate the cost-effectiveness of shunt surgery in patients with idiopathic normal pressure hydrocephalus (iNPH). METHODS: Health-related quality of life was evaluated before and 6 months after surgery using the EQ-5D-3 L (EuroQOL group five-dimensions health survey) in 30 patients (median age, 71 years; range, 65-89 years) diagnosed with iNPH. The costs associated with shunt surgery were assessed by a detailed survey with interviews and extraction of register data concerning the cost of hospital care, primary care, residential care, home-care service and informal care...

INTRODUCTION: Hyperpyrexia is a severely elevated core body temperature secondary to an elevated hypothalamic set thermo-regulatory threshold. Hyperthermia is an elevated core body temperature beyond the normal hypothalamic set thermo-regulatory threshold. Intracranial hypotension can present with a wide variety of symptoms ranging from orthostatic headache up to coma. We report a rare case of hyperpyrexia associated with intracranial hypotension. METHODS: A case report of a 55-year-old female patient with a history of angiogram-negative subarachnoid hemorrhage status post-ventriculoperitoneal (VP) shunt placement six years prior to admission who suddenly developed encephalopathy and high fever...

Regulation of the amyloid precursor protein (APP) processing by α- and β-secretases is of special interest to Alzheimer's disease (AD), as these proteases prevent or mediate amyloid beta formation, respectively. Neuroinflammation is also implicated in AD. Our data demonstrate that the endogenous mediator of inflammation prostaglandin J2 (PGJ2) promotes full-length APP (FL-APP) processing by α- and β-secretases. The decrease in FL-APP was independent of proteasomal, lysosomal, calpain, caspase, and γ-secretase activities...

INTRODUCTION: Decompressive craniectomy (DC) is a lifesaving procedure but is associated to several post-operative complications, namely cerebrospinal fluid (CSF) dynamics impairment. The aim of this multicentric study was to evaluate the incidence of such CSF alterations after DC and review their impact on the overall outcome. MATERIAL AND METHODS: We performed a retrospective multicentric study to analyze the CSF disorders occurring in children aged from 0 to 17 years who had undergone a DC for traumatic brain injury (TBI) in the major Departments of Pediatric Neurosurgery of France between January 2006 and August 2016...

OBJECTIVE Changes in the pressure gradient between intraocular and intracranial compartments at the lamina cribrosa level are a possible explanation of normal tension glaucoma (NTG). Shunt-treated normal pressure hydrocephalus (NPH) is a model for testing whether the increase (time from disease onset to CSF shunt placement, i.e., "protection period") and decrease (time from shunt placement to observation, i.e., "exposure period") in intracranial pressure (ICP) are glaucoma protective or risk factors, respectively...

Tandem internal carotid artery (ICA) origin occlusion and middle cerebral artery (MCA) thromboembolism is a life-threatening condition with poor neurological outcome. The authors report on a patient presenting with acute ischemic stroke from a tandem ICA and MCA occlusion with penumbra. Emergency MCA mechanical thrombectomy was performed through percutaneous cervical ICA access due to the inability to cross the cervical carotid occlusion. Emergency carotid endarterectomy to reperfuse the poorly collateralized hemisphere and repair the ICA access site was performed 2 hours after completion of tissue plasminogen activator (tPA) infusion...
