Jolt accentuation or exacerbation of a baseline headache with horizontal rotation of the neck is a physical finding believed to assess for meningeal irritation. We conducted a prospective observational study of neurologically intact emergency department (ED) patients undergoing lumbar puncture in 2 inner city academic EDs to validate the sensitivity and specificity of jolt accentuation and to assess the sensitivity and specificity of Kernig sign, Brudzinski sign, and nuchal rigidity, in predicting cerebrospinal fluid (CSF) pleocytosis in individuals being assessed for meningitis. Adult patients 18 years and older undergoing lumbar puncture between 2006 and 2009 were approached for consent. ⋯ The specificity of jolt accentuation was 82%, Kernig sign was 97%, Brudzinski sign was 98%, and nuchal rigidity was 80%. Jolt accentuation in our cohort was poorly predictive of pleocytosis and insensitive. The presence of Kernig sign, Brudzinski sign, or nuchal rigidity has moderate positive but no negative predictive value for pleocytosis.

A 28-year-old man presented to the emergency department (ED) 20 minutes after injecting 20 mL of an insecticide containing 0.05% β-cyfluthrin. Upon presentation, he had no complaints; and vital signs demonstrated a sinus tachycardia of 150 beats per minute, blood pressure of 140/65 mm Hg, no fever, and a normal respiratory rate. Further physical examination was notable only for the lack of tremor and the presence of a left antecubital recent injection site. ⋯ He remained asymptomatic and was transferred to the Psychiatric Assessment Unit after approximately 6 hours of observation. We present the first published case of cyfluthrin parenteral human injection. Although this patient experienced a benign clinical course, vigilance for pyrethroid toxic effects such as seizures, severe tremors, diaphoresis, and choreoathetosis is paramount.
