latent

Examples of latent in the following topics:

• Onset of Labor

  • Prodromal labor, which includes the latent phase of labor, marks the initial stages of parturition.
  • The latent phase is generally defined as beginning at the point at which the woman perceives regular uterine contractions.
  • Cervical effacement (the thinning and stretching of the cervix and cervical dilation) occurs during the closing weeks of pregnancy and are usually complete, or near complete, by the end of the latent phase.
  • The latent phase ends with the onset of the active phase, which is marked by an accelerated cervical dilation.

• Shingles

  • Shingles, the common name for herpes zoster, is caused by latent varicella zoster virus, the same virus which causes chickenpox in children.
  • Varicella zoster virus can become latent in the nerve cell bodies and less frequently in non-neuronal satellite cells of dorsal root, cranial nerve or autonomic ganglion, without causing any symptoms.
  • Exactly how the virus remains latent in the body, and subsequently re-activates is not understood.

• Syphilis

  • The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary).
  • Many people who present with secondary syphilis (40–85% of women, 20–65% of men) do not report previously having had the classic chancre of primary syphilis.LatentLatent syphilis is defined as having serologic proof of infection without symptoms of disease.
  • The United Kingdom uses a cut-off of two years for early and late latent syphilis.
  • Early latent syphilis may have a relapse of symptoms.
  • Late latent syphilis is asymptomatic, and not as contagious as early latent syphilis.

• Tuberculosis

  • Most infections are asymptomatic and latent, but about one in 10 latent infections eventually progresses to active disease which, if left untreated, kills more than 50% of those infected.
  • Latent TB treatment usually employs a single antibiotic, while active TB disease is best treated with combinations of several antibiotics to reduce the risk of the bacteria developing antibiotic resistance.
  • People with latent infections are also treated to prevent them from progressing to active TB disease later in life.

• Interactions of Skeletal Muscles

  • The time between the stimulus and the initiation of contraction is termed the latent period, which is followed by the contraction period.
  • The time between stimulation and contraction is termed the latent period.

• Syphilis

  • The signs and symptoms of syphilis vary depending on which of the four stages it presents (primary, secondary, latent, or tertiary).
  • Latent syphilis displays little to no symptoms, and neurosyphilis (tertiary) can result in neurological and cardiac symptoms because the syphilis has been undiagnosed or untreated for many years.
  • The brain and spinal cord become infected with the syphilis bacterium, Treponema pallidum, during the secondary stage of infection and can remain latent for 10 to 20 years after the initial infection.

• Type 1 Diabetes Mellitus

  • By definition, its diagnosis can be made first at the appearance of clinical symptoms and/or signs, but the emergence of autoantibodies may itself be termed "latent autoimmune diabetes".
  • Some researchers believe it might be prevented at the latent autoimmune stage, before it starts destroying beta cells.

• Bell's Palsy

  • Some viruses are thought to establish a persistent (or latent) infection without symptoms, e.g., the varicella-zoster virus, HSV-1 and Epstein-Barr viruses, all of the herpes family.
