This study assessed the effect of the agonist 15d-PGJ(2) administered into the rat temporomandibular joint (TMJ) on nociceptive behavioral and the anti-inflammatory potential of this prostaglandin on TMJ. It was observed that 15-deoxy-(Delta12,14)-prostaglandin J(2) (15d-PGJ(2)) significantly reduced formalin-induced nociceptive behavior in a dose dependent(More)
BACKGROUND Moderate to severe pain after total knee arthroplasty often interferes with postoperative rehabilitation and delays discharge from hospital. The present study examined the effects of a four-day postoperative gabapentin (GBP) regimen versus placebo on opioid consumption, pain scores and knee flexion, as well as adverse effects, after total knee(More)
INTRODUCTION Cerebral Venous Thrombosis (CVT) is a rare and potentially life-threatening disease, accounting for about 0.5% of stroke cases. However, it is believed to be an underdiagnosed condition. Early diagnosis requires a high degree of suspicion and appropriate use of imaging modalities. OBJECTIVES Imagiological and clinical characterization of CVT(More)
OBJECTIVE Orolingual angioedema (OA) is a well known early complication of treatment with alteplase in ischemic stroke patients. Our aim was to study risk factors for OA in these patients, namely insular cortex ischemia. METHODS Retrospective case-cohort study using the prospective registry of all consecutive ischemic stroke patients submitted to(More)
The novel thiourea-functionalized silicon nanoparticles (SiNPs) have been successfully synthesized using allylamine and sulforaphane, an important anticancer drug, followed by a hydrosilylation reaction on the surface of hydrogen terminated SiNPs. Their physiochemical properties have been investigated by photoluminescence emission, Fourier transform(More)
Traumatic intracranial aneurysms are rare lesions, accounting for less than 1% of all intracranial aneurysms. Formation of these lesions after a penetrating missile wound is very unusual, and diagnosis can be difficult due to the presence of associated lesions. In this article, we report a case of a woman who developed a middle cerebral artery aneurysm(More)
Hepatitis A is a common viral liver disease and brings serious health and economic problems as its epidemiologic pattern changes over time. National serosurveys from developed countries have indicated a decline in HAV (hepatitis A virus) seroprevalence over time due to the improvement of economic and sanitation levels. The hepatitis A virus (HAV) immunity(More)
In the literature regarding delirium and agitation in palliative care, there are references of their worsening as the hours of the day flows from afternoon on, with an inversion of the awake-sleep cycle. We studied the frequency of the use of our protocol for the control of agitation. From June 18, 2007, to January 4, 2010, 27 (5.3%) patients from the 509(More)
The clinical manifestations and laboratory findings of two cases of neurobrucellosis are described. The cerebrospinal fluid (CSF) protein electrophoresis showed increased gamma-globulins and decreased relative values of pre-albumin and albumin, associated to high values of total CSF protein. The evidence of oligoclonal morphology of CSF gamma-globulins(More)
Calcineurin inhibitors (CNI) are the base of immunosuppressive regimens in liver transplantation but they are associated with significant side effects, namely nephrotoxicity, which leads to increased morbidity and mortality. Through time, mycophenolate mofetil (MMF) as monotherapy has been suggested as an alternative in patients with CNI-related toxicity,(More)
