Hospital Course Summary:

Admission date: [Date]

Discharge date: [Date]

Reason for admission:

The patient, a 78-year-old woman, was admitted to the Department of Neurology after experiencing her third episode of generalized tonic clonic seizures. The patient had previously been diagnosed with a glioma and had received a resection 5 years prior.

Medical History:

The patient had been taking warfarin for 14 years as a secondary prevention measure against embolic events resulting from paroxysmal atrial fibrillation (AF). Apart from a diagnosis of glioma and warfarin use, the patient’s medical history was unremarkable.

Hospitalization course:

Upon admission, the patient was treated for status epilepticus (SE) with intravenous diazepam to terminate a five-minute episode of GTCS, followed by a loading dose of intravenous valproate sodium (1200 mg) to relieve recurrent GTCS and frequent focal aware seizures. The patient was subsequently prescribed oral levetiracetam (LEV) of 500 mg twice daily once she regained consciousness.

On the second day of admission, routine laboratory studies were conducted, which revealed unremarkable results. The patient’s ECG showed evidence of paroxysmal AF. A carotid Doppler ultrasonography was also conducted, which showed hypoechoic plaques on the anterior wall of the bifurcation of the right common carotid artery.

After 44 hours of admission and a total dosage of approximately 2200 mg of intravenous valproate sodium, the medication was discontinued. An electroencephalogram (EEG) was also conducted, which demonstrated global interictal θ waves (4-7 Hz), but without epileptiform discharges.

On the 3rd hospital day, the patient developed renal dysfunction based on the results of the BUN and serum creatinine levels, which were attributed to insufficient fluid intake. The International Normalized Ratio (INR) was found to be elevated, leading to the cessation of oral warfarin medication. A 5mg dose of vitamin K1 was administered intravenously following consultation with a hematologist. The patient remained asymptomatic and was observed without any evidences of bleeding. The repeat brain CT scan also revealed no intracranial hemorrhage. The renal dysfunction was resolved on the 4th day.

Discharge:

The patient was discharged on [Date], with oral warfarin cautiously restarted at a dose of 1.25 mg and titrated back to 1.875 mg while monitoring the INR between 2 and 3.

Follow-up:

The Neurology department recommended a follow-up with the patient in one week to monitor the improvement of her condition. The patient was advised to keep up with the fluid intake and attend regular INR monitoring sessions to check the therapeutic window of warfarin. The patient was also advised to continue taking isosorbide mononitrate and succinate metoprolol for her cardiovascular ailments.

Discharge medications:

1. Isosorbide mononitrate sustained release tablets (40 mg oral) daily.
2. Succinate metoprolol tablets (12.5 mg oral) twice daily as needed.
3. Warfarin (1.875 mg) oral, titrated to maintain INR values between 2 and 3.
