Intracranial hypotension syndrome (IHS) is generally caused by cerebrospinal fluid (CSF) leakage. Complications include bilateral subdural hygroma or haematoma and herniation of the cerebellar tonsils. Epidural blood patch (EBP) therapy is indicated if conservative treatment is ineffective. We reported the case of a 46-year-old man with a history of postural headache and dizziness. The patient was treated with bed rest and daily hydration with 2000 mL of fluid for 2 weeks. However, dizziness and headache did not resolve, and he became drowsy and disoriented with incomprehensible speech...

It has been a long time since the scientific community started to speculate upon the presence of Helicobacter pylori (HP) in periodontal pockets as an extra-gastric reservoir responsible for gastric relapses after eradication therapy. The aim of this study is to evaluate the presence of oral HP in a group of patients who underwent examination for gastric infection. Sixty patients were enrolled in the current study, subdivided into two groups: 30 patients with a positive result for HP gastric infection with C-Breath Test Urea examination, and 30 patients with a negative result for HP gastric infection...

Prominent cyst formation is an unusual feature of liposarcoma. We report here a case of dedifferentiated liposarcoma with huge cystic change without preoperative chemo- or radiation therapy. The lesion arose in the retroperitoneum juxtaposed to the right kidney of a 67-year-old woman. She underwent a surgical removal of the retroperitoneal cyst. The cystic tumor contained 1600 mL of old bloody fluid, and its wall was composed of edematous, inflamed or sclerosing fibrous tissue with fatty tissue containing abundant atypical stromal cells, which were immunohistochemically positive for MDM2 and CDK4, and demonstrated MDM2 gene amplification by fluorescence in situ hybridization...

Most people who make the transition to maintenance dialysis therapy are treated with a fixed dose thrice-weekly hemodialysis regimen without considering their residual kidney function (RKF). The RKF provides effective and naturally continuous clearance of both small and middle molecules, plays a major role in metabolic homeostasis, nutritional status, and cardiovascular health, and aids in fluid management. The RKF is associated with better patient survival and greater health-related quality of life, although these effects may be confounded by patient comorbidities...

An 11-year-old African American male with severe combined immunodeficiency variant, non-cystic fibrosis bronchiectasis, pancreatic insufficiency, chronic mycobacterium avium-intracellulare infection, chronic sinusitis, and malnutrition presented with a 1-week history of fevers. He subsequently developed respiratory decompensation and cefepime was discontinued and doripenem was initiated. Doripenem was the carbapenem used due to a national shortage of meropenem. By day 7 the patient (24.7 kg) had a positive fluid balance of 6925 mL (28% FO), and on days 7 into 8 developed acute kidney injury evidenced by an elevated serum creatinine of 0...

Traumatic brain injury (TBI) is a serious public health problem, often with devastating consequences for patients and their families. Affordable and timely therapies can have a substantial impact on outcomes in severe TBI. Despite the common use of sedatives and anesthetics in the acute phase of TBI management, their effect on glial cells is not well understood. We investigated the effect of a commonly used sedative, pentobarbital, on glial cells and their uptake of nanoparticles. First, we studied how pentobarbital affects BV2 mouse microglial cells in culture...

Various eye conditions cause tears in the retinal pigment epithelium (RPE). The most common cause of an RPE tear is vascularized retinal pigment epithelial detachment (PED) in patients with exudative age-related macular degeneration. Although RPE tears can develop spontaneously in vascularized PEDs, most recent cases have been associated with anti-vascular endothelial growth factor (VEGF) injections. The subretinal fluid within the PED applies hydrostatic pressure to the RPE and stretches it. The PED enlarges as the hydrostatic pressure increases...

Obtaining patient-specific information through the quantification of small molecules and proteins in bodily fluids is essential for personalized therapies. Point-of-care (POC) diagnostic devices hold the promise of delivering such benefit to a wide range of patients. However, there is a lack of enabling technology, as the majority of newly developed POC devices focus on the same underlying core technologies. Here we provide an overview of a new technology based on highly modular bioluminescent sensors that enables the quantification of small molecules and proteins at the POC with low-cost devices...

Traumatic brain injury (TBI) continues to be a serious healthcare issue while therapies to treat TBI remain elusive. Promising results from the use of endothelial progenitor cells (EPCs) in numerous disease states highlight the pleiotropic capacity of this cell type. We have previously demonstrated that EPC conditioned media reduces axonal degeneration following in vitro OGD insult and concurrently improves white matter and microvascular outcome in vivo following midline fluid percussion injury. In the current study we evaluated the effectiveness of allogeneic endothelial cells derived from rat bone marrow on microvascular recovery and neuronal sparing following lateral fluid percussion injury...

The physiological changes accompanying inflammation may alter the pharmacokinetics (PK) of certain medications. Individuals infected with HIV have chronically elevated inflammatory markers despite viral suppression following effective antiretroviral therapy (ART), as well as age-related inflammation. Understanding the potential clinical implications of inflammation on the PK of medications is important for understanding dose-response relationships and necessitates future research. Areas covered: An extensive literature search was carried out using PubMed and associated bibliographies to summarize the current state of knowledge regarding altered PK in response to inflammation and its application to the field of HIV...

Gene therapy is a promising therapeutic alternative for Lysosomal Storage Disorders (LSD), as it is not necessary to correct the genetic defect in all cells of an organ to achieve therapeutically significant levels of enzyme in body fluids, from which non-transduced cells can uptake the protein correcting their enzymatic deficiency. Animal models are instrumental in the development of new treatments for LSD. Here we report the generation of the first mouse model of the LSD Muccopolysaccharidosis Type IIID (MPSIIID), also known as Sanfilippo syndrome type D...
