| 释义 |
| name = Meningism | synonyms = Meningismus[1][2] pseudomeningitis,[1][3] | symptoms = | complications = | onset = | duration = | types = | causes = | risks = | diagnosis = | differential = | prevention = | treatment = | medication = | prognosis = | frequency = | deaths = }} Meningism is a set of symptoms similar to those of meningitis but not caused by meningitis.[1][3][4] Whereas meningitis is inflammation of the meninges (membranes that cover the central nervous system), meningism is caused by nonmeningitic irritation of the meninges, usually associated with acute febrile illness,[1][2] especially in children and adolescents.[2] Meningism involves the triad (3-symptom syndrome) of nuchal rigidity (neck stiffness), photophobia (intolerance of bright light) and headache. It therefore requires differentiating from other CNS problems with similar symptoms, including meningitis and some types of intracranial hemorrhage. Related clinical signs include Kernig's sign and three signs all named Brudzinski's sign. Although nosologic coding systems such as ICD-10 and MeSH define meningism/meningismus as meningitis-like but in fact not meningitis, many physicians use the term "meningism" in a loose sense clinically to refer to any meningitis-like set of symptoms before the cause is definitively known. In this sense, the word implies "suspected meningitis". The words "meningeal symptoms" can be used instead to avoid confusion between the word senses, thus reserving the term "meningism" for its strict sense. Readers of the medical literature should remain aware that the words are used in more than one sense. Signs and symptomsThe main clinical signs that indicate meningism are nuchal rigidity, Kernig's sign and Brudzinski's signs. None of the signs are particularly sensitive; in adults with meningitis, nuchal rigidity was present in 30% and Kernig's or Brudzinski's sign only in 5%.[5] Nuchal rigidityNuchal rigidity is the inability to flex the neck forward due to rigidity of the neck muscles; if flexion of the neck is painful but full range of motion is present, nuchal rigidity is absent.{{Citation needed|date=October 2009}} Kernig's signKernig's sign (after Waldemar Kernig (1840–1917), a Russian neurologist) is positive when the thigh is flexed at the hip and knee at 90 degree angles, and subsequent extension in the knee is painful (leading to resistance).[6] This may indicate subarachnoid hemorrhage or meningitis.[7] Patients may also show opisthotonus—spasm of the whole body that leads to legs and head being bent back and body bowed forward.{{Citation needed|date=May 2008}} Brudzinski's signs{{main|Brudziński sign}}Jozef Brudzinski (1874–1917), a Polish pediatrician, is credited with several signs in meningitis. The most commonly used sign (Brudzinski's neck sign) is positive when the forced flexion of the neck elicits a reflex flexion of the hips, with the patient lying supine.[5][8]Other signs attributed to Brudzinski:[9]
