Pseudotumoral presentation of cerebral amyloid angiopathy-related inflammation

Conclusion: The identification of one or several nonenhancing space-occupying lesions, especially in elderly patients presenting with cognitive impairment, should raise suspicion for the pseudotumoral presentation of CAA-I and lead to T2*-GRE sequences. Perfusion MRI and MRS appear to be useful techniques for the differential diagnosis of this entity.

Authors: Osei-Owusu J, Yang J, Del Carmen Vitery M, Tian M, Qiu Z Abstract Severe local acidosis causes tissue damage and pain, and is associated with many diseases, including cerebral and cardiac ischemia, cancer, infection, and inflammation. However, the molecular mechanisms of the cellular response to extracellular acidic environment are not fully understood. We recently identified a novel and evolutionarily conserved membrane protein, PAC (also known as PACC1 or TMEM206), encoding the proton-activated chloride (Cl-) channel, whose activity is widely observed in human cell lines. We demonstrated that genetic del...

Authors: Peri A Abstract In hypotonic hyponatremia, which is the most common form of hyponatremia, clinical manifestations are largely due to brain swelling caused by entry of water into the cells. In acute and severe hyponatremia, dramatic symptoms, such as seizures, acute psychosis, permanent brain damage, brain-stem herniation, leading to coma and death may occur. In chronic hyponatremia, symptoms are generally less dramatic and may include headache, nausea, vomiting, gait alterations, muscle cramps, restlessness, and disorientation. It has become evident in recent years that mild forms of chronic hyponatremia m...

Authors: Hew-Butler T Abstract Exercise-associated hyponatremia (EAH) refers to below-normal serum sodium concentrations [Na+] that develop during exercise. The pathogenesis of EAH is best described as a spectrum ranging between profound polydipsia to modest sweat sodium losses with hypovolemia and relative dilution. Non-osmotic arginine vasopressin (AVP) remains the unifying pathogenic stimulus to abnormal renal water retention in acute symptomatic EAH. Cases of hyponatremia are mostly reported after endurance sports, but are also observed after shorter duration events and in team sport athletes. The signs and sym...

Authors: Hannon MJ, Thompson CJ Abstract Hyponatremia is a frequent occurrence in patients with neurosurgical disorders. Acute onset hyponatremia is particularly common in patients who have any type of cerebral insult, including traumatic brain injury, subarachnoid hemorrhage, and brain tumors. Furthermore, it is a common complication of intracranial procedures. Acute hyponatremia creates an osmotic gradient between the brain and the plasma, which promotes the movement of water from the plasma into brain cells, causing cerebral edema and neurological compromise. It is therefore far more likely to be symptomatic, an...

This study was performed in Zhongshan Hospital, Fudan University, China. 803 patients with hypertension were consecutively recruited from 2012 to 2015. All participants underwent routine biochemical measurements, including plasma renin activity (PRA) and plasma aldosterone concentration (PAC). In all patients with a PAC higher than 10 ng/dl, a saline perfusion test was conducted, and a CT scan or adrenal venous sampling was also performed if needed. Receiver operating characteristic (ROC) analysis was conducted in all eGFR

CONCLUSIONS: Melatonin protected SH SY5Y cells from OGD/R induced oxidative stress, inflammation, apoptosis, and autophagy by blocking NF-κB signaling and activating Nrf2/HO-1, Akt, and mTOR/p70S6K/4E-BP-1 pathways, thereby indicating that melatonin is a potential and novel therapeutic drug for ischemic stroke.
