At an acute ingestion of arsenic trioxide, nausea, vomiting, diarrhea, and abdominal pain are early symptoms occurring within 30 min to several hours. Primary target organ is the gastrointestinal tract (GIТ), where hemorrhagic gastroenteritis can occur in serious cases. Among cardiovascular symptoms are tachycardia, ventricular fibrillation, and heart failure described. Neurological symptoms ca...

adequately ventilate), or both hypoxic and hypercapnic. In addition, respiratory failure can be caused by an inability to protect the airway. Alterations in the normal physiology and anatomy of the respiratory system can lead to respiratory failure requiring mechanical ventilation. Anatomic alterations causing airway obstruction, such as tumors, edema, direct or indirect trauma, burns, or other...

BACKGROUND AND PURPOSE A cavernous angioma is a developmental vascular malformation with a high risk of hemorrhage. The purpose of this work was to retrospectively determine whether an MR sign of T1 hyperintense perilesional signal intensity is useful for the differentiation of cavernous angioma from other hemorrhagic cerebral masses. MATERIALS AND METHODS The institutional review board appro...

background: magnetic resonance imaging (mri) is a safe modality and useful in characterizing normal and abnormal bone marrow (bm). mri also presents a more global view of bm than biopsy therefore, it may provide a better understanding of hematologic disorders. the purpose of this study was to monitor radiation-induced alterations of bm in acute phase of irradiation (1-10 day after total body ir...

A 40-year-old woman presented to the emergency department with acute decreased level of consciousness, associated with respiratory failure. She has complained of headache, fever, myalgia and dyspnea for the last seven days. Neurological examination disclosed decreased level of consciousness. Brain CT scan disclosed multiple intracerebral acute hemorrhage lesions (Figure). After extensive invest...

PURPOSE The role of adenosine and its receptors in acute pancreatitis remains unelucidated. The aim was to evaluate the effects of the adenosine A2a receptor agonist and antagonist in the severe, taurocholate-induced experimental acute pancreatitis (EAP). MATERIAL AND METHODS The experiments were performed on 80 male Wistar rats, subdivided into 4 groups: C--the control rats, I--the EAP group...

BACKGROUND Cerebral contusions have a 51% incidence of evolution in the first hours after injury. Evolution is associated with clinical deterioration and is the reason for ICP monitoring or surgical intervention. We sought to define CT features that predict cerebral contusion evolution. METHODS Patients treated for cerebral contusion who had 2 CT scans within 24 hours after injury were evalua...

We tested the hypothesis that astrocytic matrix metalloproteinase-9 (MMP-9) mediates hemorrhagic brain edema. In a clinical case of hemorrhagic stroke, MMP-9 co-localized with astrocytes and neurons in peri-hematoma areas. In a mouse model where blood was injected into striatum, MMP-9 was colocalized with astrocytes surrounding the hemorrhagic lesion. Because MMP-9 is present in blood as well a...

Abstract Background Lingual edema is usually the result of infectious etiology, angioedema, and less commonly traumatic etiology. As for therapeutic approach, first priority excluding airway compromise or ensuring safety. Antibiotic treatment should be administered tongue swelling inflammatory etiology while standard therapy with epinephrine, steroids, antihistamines recommended cases anaphylax...
