BACKGROUND: Increasing the mean arterial pressure (MAP) is an accepted treatment modality to minimize the risk for irreversible neurologic damage secondary to spinal cord ischemia. Posterior reversible encephalopathy syndrome (PRES) is a rare complication occurring after transplantation surgery, in persons having an autoimmune disorder or after abrupt increases in blood pressure of various etiologies. STUDY DESIGN: Case report. METHODS: Retrospective evaluation of medical records...

Hepatic encephalopathy (HE) is a neuropsychiatric disorder that commonly complicates the course of patients with liver disease. Despite the fact that the syndrome was probably first recognized hundreds of years ago, the exact pathogenesis still remains unclear. Minimal hepatic encephalopathy (MHE) is the earliest form of HE and is estimated to affect more that 75% of patients with liver cirrhosis. It is characterized by cognitive impairment predominantly attention, reactiveness and integrative function with very subtle clinical manifestations...

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease associated with repetitive mild impact traumatic brain injury from contact sports. Recently, a consensus panel defined the pathognomonic lesion for CTE as accumulations of abnormally hyperphosphorylated tau (p-tau) in neurons (neurofibrillary tangles), astrocytes and cell processes distributed around small blood vessels at sulcal depths in irregular patterns within the cortex. The pathophysiological mechanism for this lesion is unknown. Moreover, a subset of CTE cases harbors cortical β-amyloid plaques...

BACKGROUND: Minimal hepatic encephalopathy (MHE) is not associated with overt neuropsychiatric symptoms but rather with subtle changes in psychometric and/or neurophysiologic tests. We aimed to diagnose MHE in children with extrahepatic portal vein obstruction (EHPVO) and to evaluate the effect of lactulose on MHE. METHODS: A prospective study was carried out on 30 patients with EHPVO (21 males; mean age 10±2.5 years). The study was carried out in the Pediatric Hepatology Unit, Cairo University Pediatric Hospital, Cairo, Egypt, between 2011 and 2013...

Wnt signaling plays a key role in neuroprotection and synaptic plasticity. We speculate that the impairment of Wnt signaling may mediate astrocytic neurotrophins (NTs) production and the impairment of Wnt signaling to astrocytic NTs production contributes to the pathogenesis of minimal hepatic encephalopathy (MHE). Here, we found that induction of astrocytic NTs synthesis was by Wnt5a via the calcium/calmodulin-sensitive protein kinase II (CaMK II)-cAMP-response element-binding protein (CREB) pathway in PCAs...

BACKGROUND AND AIMS: Data on minimal hepatic encephalopathy (MHE) in children is scanty. We evaluated children with chronic liver disease (CLD) to determine prevalence of MHE, its correlation with changes in brain metabolites by magnetic resonance spectroscopy ((1)HMRS), diffusion tensor imaging (DTI) derived metrics, blood ammonia (BA) and inflammatory cytokines and the accuracy of MR based investigations for diagnosis METHODS: 67(38 boys; age 13[7-18] years) CLD and 37 healthy children were evaluated with neuropsychological tests (NPT), BA, interleukin-6 [IL6], tumor necrosis factor alpha [TNFα], magnetic resonance imaging (MRI),(1)HMRS and DTI...

Advanced age and associated comorbidities are-recognized predictors of life-threatening adverse outcomes, such as opportunistic infection following immunosuppressive therapy. We describe the case of an elderly patient with stricturing colonic Crohn's disease and significant clinical comorbidities, initially controlled with corticosteroid induction followed by infliximab, whose course was complicated by fatal disseminated cryptococcal infection and posterior reversible encephalopathy syndrome. Our patient's case highlights rare, but serious, complications of immunosuppression...

Inhibition of thiamine transporters has been proposed as a putative mechanism for the observation of Wernicke's encephalopathy and subsequent termination of clinical development of fedratinib, a Janus Kinase inhibitor (JAKi). This study aimed to determine the potential for other JAKi to inhibit thiamine transport using Caco-2 and thiamine transporter (THTR) over-expressing cells and to better elucidate the structural basis for interacting with THTR. Only JAKi containing a 2,4-diaminopyrimidine were observed to inhibit thiamine transporters...

Transjugular intrahepatic portosystemic shunt (TIPS) has become an important minimally invasive interventional technique for the treatment of complications of cirrhotic portal hypertension, and currently, it is often used in cirrhotic patients with esophagogastric variceal bleeding (EVB), intractable ascites, hepatic hydrothorax, and Budd-Chiari syndrome. On one hand, TIPS can effectively reduce portal vein pressure and the risk of EVB and intractable ascites; on the other hand, it may reduce the blood flow in liver perfusion, aggravate liver impairment, and cause porto-systemic encephalopathy...

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disorder which may result from repetitive brain injury. A variety of tau-immunoreactive pathologies are present, including neurofibrillary tangles (NFT), neuropil threads (NT), dot-like grains (DLG), astrocytic tangles (AT), and occasional neuritic plaques (NP). In tauopathies, cellular inclusions in the cortex are clustered within specific laminae, the clusters being regularly distributed parallel to the pia mater. To determine whether a similar spatial pattern is present in CTE, clustering of the tau-immunoreactive pathology was studied in the cortex, hippocampus, and dentate gyrus in 11 cases of CTE and 7 cases of Alzheimer's disease neuropathologic change (ADNC) without CTE...

Mutations in GABAA receptor subunit genes are frequently associated with epilepsy, and nonsense mutations in GABRG2 are associated with several epilepsy syndromes including childhood absence epilepsy, generalized tonic clonic seizures and the epileptic encephalopathy, Dravet syndrome. The molecular basis for the phenotypic heterogeneity of mutations is unclear. Here we focused on three nonsense mutations in GABRG2 (GABRG2(R136*), GABRG2(Q390*) and GABRG2(W429*)) associated with epilepsies of different severities...

BACKGROUND: It has been observed that patients with liver dysfunction need lower dose anesthetic compared patients with normal liver function. The minimum amount of volatile anesthetic to achieve an optimal depth of anesthesia for these patients is still unclear. In this study, Minimum alveolar concentration (MAC) of the sevoflurane was determined using an electric stimulation and the effect of severity of liver dysfunction on the MAC was observed in cirrhotic patients. METHODS: Thirty patients undergoing upper abdominal surgery were divided into the following groups: group N (normal liver function), group A (Child-Pugh grade A) and group B (Child-Pugh grade B-C)...
