hemorrhagic

Examples of hemorrhagic in the following topics:

• Classic Viral Hemorrhagic Fevers

  • Viral hemorrhagic fevers (VHFs) are a group of illnesses that are caused by several distinct families of RNA viruses.
  • The family Arenaviridae include the viruses responsible for Lassa fever, Lujo virus, Argentine, Bolivian, Brazilian and Venezuelan hemorrhagic fevers.
  • The family Bunyaviridae include the members of the Hantavirus genus that cause hemorrhagic fever with renal syndrome (HFRS), the Crimean-Congo hemorrhagic fever (CCHF) virus from the Nairovirus genus, Garissa virus from the Orthobunyavirus and the Rift Valley fever (RVF) virus from the Phlebovirus genus.
  • For most viral hemorrhagic fevers, there is no effective treatment other than supportive care.

• Emerging Viral Hemorrhagic Fevers

  • As human habitation expands, new viral hemorrhagic fevers are infecting humans.
  • The viral hemorrhagic fevers (VHFs) are a diverse group of animal and human illnesses that may be caused by five distinct families of RNA viruses: the families Arenaviridae, Filoviridae, Bunyaviridae, Flaviviridae, and Rhabdoviridae.
  • Indeed the advent of deep sequencing technologies and other methods are identifying emergent viral hemorrhagic fevers.
  • A recent study using deep sequencing, discovered a novel rhabdovirus (Bas-Congo virus, or BASV) associated with a 2009 outbreak of three human cases of acute hemorrhagic fever in Mangala village, Democratic Republic of Congo (DRC), Africa.
  • Although the source of the virus remains unclear, the study findings suggest that BASV may be spread by human-to-human contact and is an emerging pathogen associated with acute hemorrhagic fever in Africa .

• Hantavirus

  • Hantaviruses are negative-sense RNA viruses that sometimes lead to hemorrhagic fever with renal syndrome in humans.
  • Although some hantaviruses lead to potentially fatal diseases, such as hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS), not all are associated with human disease.
  • HTNV is one of several hantaviruses that cause hemorrhagic fever with renal syndrome (HFRS), formerly known as Korean hemorrhagic fever.

• Cystitis

  • Hemorrhagic cystitis can occur as a side effect of cyclophosphamide, ifosfamide, and radiation therapy.
  • Radiation cystitis, one form of hemorrhagic cystitis is a rare consequence of patients undergoing radiation therapy for the treatment of cancer.
  • Several adenovirus serotypes have been associated with an acute, self-limited hemorrhagic cystitis, which occurs primarily in boys.
  • Differentiate among the distinct types of cystitis: traumatic, interstitial, eosinophilic, hemorrhagic cystitis, and cystitis cystica, recognizing their causes and risk factors

• Aspirin and Thrombolytic Agents

  • Excessive intake of aspirin can increase the possibility of hemorrhage, also a cause of morbidity and mortality.
  • Although aspirin also raises the risk of hemorrhagic stroke and other major bleeds by about twofold, these events are rare, and the balance of aspirin's effects is positive.
  • In addition, the risks of hemorrhagic strokes and gastrointestinal bleeding offset the benefits of aspirin.

• Spinal Tap

  • In any age group, subarachnoid hemorrhage, hydrocephalus, benign intracranial hypertension, and many other conditions may be diagnosed with this test.
  • Increased CSF pressure: can indicate conditions causing increased intracranial pressure, such as congestive heart failure, cerebral edema, subarachnoid hemorrhage, meningeal inflammation, purulent meningitis or tuberculous meningitis, hydrocephalus, or pseudotumor cerebri.
  • White cells can also indicate reaction to repeated lumbar punctures, reactions to prior injections of medicines or dyes, central nervous system hemorrhage, leukemia, recent epileptic seizure, or a metastatic tumor.
  • The finding of erythrophagocytosis, where broken-up erythrocytes are observed in the fluid, and signifies hemorrhage into the CSF that preceded the lumbar puncture.

• Safety in the Microbiology Laboratory

  • Viruses and bacteria that cause severe to fatal disease in humans, and for which vaccines or other treatments are not available, such as Bolivian and Argentine hemorrhagic fevers, Dengue hemorrhagic fever, Marburg virus, Ebola virus, hantaviruses, Lassa fever virus, Crimean-Congo hemorrhagic fever, and other hemorrhagic diseases.

• Transcytosis

  • Shiga toxin secreted by entero-hemorrhagic E. coli has been shown to be transcytosed into the intestinal lumen.

• Cerebrovascular Accident

  • This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis, arterial embolism) or a hemorrhage (leakage of blood).
  • An ischemic stroke is occasionally treated in a hospital with thrombolysis (also known as a "clot buster"), and some hemorrhagic strokes benefit from neurosurgery.
  • Infarcts are more likely to undergo hemorrhagic transformation (leaking of blood into the damaged area) than other types of ischemic stroke.

• Back Injuries and Heavy Lifting

  • This results in misplaced force application within the spine, often resulting in hemorrhage of disks within the spinal column.
