I have enough clinical context. Here is the HoPI:
History of Present Illness (HoPI)
Master [Name], a [X]-year-old male child, previously immunized and developmentally appropriate for age, was apparently well until 5 days prior to admission, when he developed high-grade, continuous fever with no diurnal variation, rising up to 39.5-40°C (103-104°F), not relieved adequately by antipyretics, with no associated chills or rigors at onset.
3 days prior to admission, the fever was noted to be persistent. He became increasingly irritable, refused feeds, and his parents noticed that he was not making eye contact and was unusually inconsolable. He stopped responding to his name and showed altered responsiveness - appearing drowsy and confused at times.
2 days prior to admission, he developed abnormal body movements in the form of generalized tonic-clonic jerking involving all four limbs, lasting approximately 2-3 minutes, with associated uprolling of eyeballs, frothing from the mouth, and urinary incontinence. The episode was followed by a postictal period of decreased consciousness lasting around 30 minutes. He had 2 such episodes in the following 24 hours.
Associated symptoms include: vomiting (non-projectile, 2-3 episodes/day), headache (as reported by the child/inferred from excessive crying and head-holding), and photophobia (excessive crying on exposure to light). There was no preceding trauma, no history of contact with a sick individual, no rash noted at home, and no prior similar episodes.
There is no history of ear discharge, loose stools, urinary complaints, skin rash, or recent travel to a malaria-endemic zone.
The child was brought to the emergency department in a state of altered sensorium (GCS 10/15 - E3V3M4), with ongoing fever and a bulging anterior fontanelle (if applicable by age).
Key points captured in this HoPI:
- Prodrome of fever before neurological deterioration (classic for bacterial meningitis/encephalitis)
- Progressive altered sensorium - irritability progressing to unresponsiveness (AEIOU-TIPS framework: Infection category)
- Complex febrile seizures - raising suspicion for meningitis beyond simple febrile seizure threshold
- Meningeal irritation signs hinted through photophobia and headache
- Absence of red flags for alternate diagnoses (trauma, intoxication)
- Age-appropriate caveats (nuchal rigidity may be absent under age 2; bulging fontanelle is an important substitute sign)
Tintinalli's Emergency Medicine notes: "A bulging fontanelle, vomiting, irritability that increases when the infant is held, inconsolability, or a complex febrile seizure may be the only signs suggestive of meningitis" in young children where classic signs are absent.
