A 71-year-old man presented with a continuous generalized tonic-clonic seizure of 80 minutes duration. Multiple attempts to establish an IV line failed. Ten milligrams of midazolam hydrochloride was administered IM and was followed by prompt termination of seizure activity. This report discusses the pharmacokinetic and anticonvulsant properties of midazolam as an alternative to diazepam for the initial treatment of status epilepticus.

Posterior reversible encephalopathy syndrome (PRES) is an unfamiliar term to anesthesiologists, and this is characterized by neurologic symptoms that include mental change, headache, seizure and visual disturbance and also abnormal neuroimaging finding. A 71-year-old female patient was operated on for posterior decompression and total laminectomy under general anesthesia for the spinal stenosis. After the operation, she developed generalized tonic-clonic seizure and a stuporous mentality in the recovery room. The magnetic resonance imaging (MRI) revealed swelling and increased signal intensity at the deep gray nuclei, cerebral cortex and cerebellum. After one week, she returned to an alert mentality and then she was diagnosed with PRES. She was discharged without any neurologic deficit on postoperative day 20. This report describes our experience with PRES after spinal surgery was performed under general anesthesia on a suspected untreated hypertensive patient.

BACKGROUND Percutaneous catheter radiofrequency ablation (RFA) and cryoablation of the left atrium and pulmonary vein ostia have become successful therapeutic modalities in the management of atrial fibrillation. Atrio-esophageal fistula is a rare complication. Awareness of complication risk is imperative because without prompt diagnosis and urgent surgical intervention, the outcome is often fatal. We present 3 cases of atrio-esophageal fistula following percutaneous catheter radiofrequency ablation (RFA). CASE REPORT Case 1: A 72-year old white male presented 27 days after percutaneous RFA for atrial fibrillation with fever, altered mental status, and melena. Esophagogastroduodenoscopy (EGD) revealed a 1-cm defect in the mid-esophagus. Upon thoracotomy, severe hemorrhage ensued from a concomitant injury to the left atrium. Multiple attempts to repair the left atrial perforation were unsuccessful and the patient died. Case 2: A 71-year old white male presented 29 days after percutaneous RFA for atrial fibrillation with fever and tonic-clonic seizure. Recognition of possible atrio-esophageal fistula was considered and confirmed on thoracotomy. Surgical fixation of the left atria and esophagus were performed. The patient survived and was discharged to a skilled care facility. Case 3: A 75-year old white male presented 24 days after percutaneous RFA for atrial fibrillation with chest pain. An echocardiogram revealed a large pericardial effusion and pericardiocentesis was performed. Despite aggressive measures, the patient died. The autopsy demonstrated a communicating esophageal fistula with the right pulmonary vein. CONCLUSIONS Clinicians tending to patients who have recently undergone atrial ablation need to be aware of atrio-esophageal fistula as a rare but highly fatal complication.

Background: Though Todd's phenomenon (TP) is a relatively rare occurrence, its correct identification is of key diagnostic and therapeutic importance as a stroke mimic. Here we describe a case of isolated gaze palsy as a manifestation of TP, discuss periictal gaze abnormalities as lateralizing sign involving the frontal eye field (FEF), and present a narrative literature review. Methods: We reviewed the main features of the case and conducted a structured literature search of TP and gaze palsy using PubMed. We restricted the search to publications in English, Spanish, French, and German. Case presentation: A 71-year-old male with a history of right frontotemporal subarachnoid hemorrhage was admitted to the Emergency Department of our institution after suffering a first unprovoked focal to bilateral tonic-clonic seizure with ictal gaze deviation to the left. Cranial imaging showed no signs of ischemia, intracerebral hemorrhage, or tumor. The patient presented the following postictal features: involuntary eye deviation to the right due to left-sided gaze palsy and disorientation in time with preserved responsiveness. Eye movements were normal three days later. We concluded that the patient suffered from new-onset epilepsy due to sequelae following the right frontotemporal subarachnoid hemorrhage, affecting the FEF with contralateral ictal gaze deviation, and postictal gaze palsy with ipsilateral eye deviation as an unusual Todd's phenomenon. Conclusion: Unusual manifestations of TP are uncommon but clinically highly relevant, as they can mimic stroke or epileptic status and are decisive in the diagnostic and therapeutic decision-making process. Though postictal gaze palsy has been reported associated with other deficits, this constitutes, to our knowledge, the first report of isolated gaze palsy as a form of TP. Further research into the underlying causes is needed. Ictal contralateral gaze and head deviation, and probably postictal ipsilateral gaze deviation if present, are very helpful for the lateralization of the seizure-onset zone.
