Study Notes
Febrile Seizures
- A 14-month-old girl presents with generalized tonic-clonic seizure after waking from a nap, with a history of mild rhinorrhea.
- She is alert and responsive, with a temperature of 39.8°C (103.6°F).
- The most appropriate next step in management is reassurance.
- The patient's clinical picture is consistent with a simple febrile seizure, which is common in children aged 6 months to 6 years.
- Simple febrile seizures are generalized, last less than 15 minutes, and typically occur in the context of a febrile illness.
- Simple febrile seizures are generally self-limited and do not require treatment or carry a high risk for future epilepsy.
- A thorough history and physical examination are essential to differentiate simple febrile seizures from complex seizures caused by viral or bacterial central nervous system infections.
- A CT scan of the head is not indicated in this case, as the patient does not exhibit focal neurological signs or altered mental status.
- Anticonvulsant therapy is not necessary for simple febrile seizures, as they are typically self-limited.
- An EEG is not required for simple febrile seizures, as the seizure duration is less than 15 minutes in the context of a febrile illness.
- A lumbar puncture is not necessary for simple febrile seizures, as the patient does not exhibit symptoms suggestive of meningitis or encephalitis.
Thyroid Storm
- Thyroid storm is a serious complication of hyperthyroidism.
- Occurs in patients with a known diagnosis of hyperthyroidism after physiologic stress, such as infection, surgery, or trauma.
- Presents with vital sign instability, mental status changes (agitation, obtundation, or coma), tremor, seizures, hyperreflexia, diaphoresis, nausea, diarrhea, and potential high-output heart failure.
Thyroid Storm Assessment
- Initial diagnosis of thyroid storm is made through a combination of clinical features and thyroid function testing.
- Increased serum concentrations of triiodothyronine (T3) and thyroxine (T4), and a decreased concentration of thyroid-stimulating hormone (TSH) are indicators.
Thyroid Storm Management
- Supportive care is required.
- Treatment of the underlying provocative stress is crucial.
- Intravenous corticosteroids, beta-adrenergic blockers, propylthiouracil, and potassium iodide are used.
Other Diagnostic Considerations
- Blood culture can be used to diagnose bacteremia and sepsis.
- Complete blood count with differential may disclose neutrophilia in the setting of pneumonia or leukocytosis in the setting of thyroid storm.
- CT scan of the head is helpful for excluding intracranial mass lesions prior to performing a lumbar puncture in patients with meningitis.
- Measurement of serum calcium and magnesium concentrations can help assess potential causes of hyperreflexia.
