The pt is a previously well 6 year old male who received flu shot on 11/5/03. On the morning of 11/6/03 complained of a headache and stomachache. The pt was sent to home and sent back home from school an hour later. The pt vomited times three at home and in between very sleepy. The pt came downstairs in the afternoon and became acutely confused while sitting next to mom. He could not recognize his sister, his mom, or a glass of water. He simply said "I don't know" and shrug his shoulders while staring off. The pt then became limp and unresponsive and the mom laid him down and called 911. By the time the paramedics arrived, the child had jerking motions of his arms and body which mom estimates to have occurred for approximately five minutes. The paramedics told the mom that he was having a seizure. They brought him to ER for further evaluation and treatment. His temp at the time the paramedics arriving was 99.8 and there was confusion as to whether his temp in the child ER was 100.3 or 103. The pt remained unresponsive for the next hour to hours while at ER. CT scan of the head was done which was normal. WBC was 10.7, segs 93, no bands, 4 lymphocytes, 3 monocytes, hemoglobin 12.5, platelet count 315,000, electrolytes with sodium 134, potassium 4.1, chloride 100, bicarb 22, glucose 148, bun 13, creatinine 0.6, total protein 7.2, albumin 4, globulin 3.2, calcium 10, bilirubin 0.2, sgot 22, sgpt 34, alk phos 282, urinalysis is yellow, cloudy, specific gravity 1.020, ph 6.5, dipstick negative except for blood 1+ and 37 red cells, 0-2 white cells, urate crystals.
