RESUMO
OBJECTIVE: Postictal psychiatric symptoms (PPS) are a relatively common but understudied phenomenon in epilepsy. The mechanisms by which seizures contribute to worsening in psychiatric symptoms are unclear. We aimed to identify PPS prospectively during and after admission to the epilepsy monitoring unit (EMU) in order to characterize the postictal physiologic changes leading to PPS. METHODS: We prospectively enrolled patients admitted to the EMU and administered repeat psychometric questionnaires during and after their hospital stay in order to assess for postictal exacerbations in four symptom complexes: anger/hostility, anxiety, depression, and paranoia. Electroclinical and electrographic seizures were identified from the EEG recordings, and seizure durations were measured. The severity of postictal slowing was calculated as the proportion of postictal theta/delta activity in the postictal EEG relative to the preictal EEG using the Hilbert transform. RESULTS: Among 33 participants, 8 demonstrated significant increases in at least one of the four symptoms (the PPS+ group) within three days following the first seizure. The most common PPS was anger/hostility, experienced by 7/8 participants with PPS. Among the 8 PPS+ participants, four experienced more than one PPS. As compared to those without PPS (the PPS- group), the PPS+ group demonstrated a greater degree of postictal EEG slowing at 10 min (p = 0.022) and 20 min (p = 0.05) following seizure termination. They also experienced significantly more seizures during the study period (p = 0.005). There was no difference in seizure duration between groups. SIGNIFICANCE: Postictal psychiatric symptoms including anger/hostility, anxiety, depression, and paranoia may be more common than recognized. In particular, postictal increases in anger and irritability may be particularly common. We provide physiological evidence of a biological mechanism as well as a demonstration of the use of quantitative electroencephalography toward a better understanding of postictal neurophysiology.

OBJECTIVE: Description of a series of cases in which otogenic encephaloceles in patients requiring canal wall down (CWD) mastoidectomies were repaired via a transmastoid approach. STUDY DESIGN: Case series. SETTING: Tertiary-care hospital. PATIENTS: Eleven cases of otogenic encephaloceles in patients requiring CWD mastoidectomy for chronic ear disease. INTERVENTIONS: Surgical repair of an otogenic encephalocele using a transmastoid approach. MAIN OUTCOME MEASURES: Success of repair, number and size of defects, materials used for repair, complications encountered in surgery, pure tone average air-bone gap (PTA-ABG). RESULTS: Eleven cases were identified. Two of these patients had a prior CWD cavity while the remainder received CWD mastoidectomy simultaneously with encephalocele repair. None of the patients required revision of encephalocele repair. Mean preoperative PTA-ABG was 30âdB and mean postoperative PTA-ABG was 28âdB (pâ=â0.66). CONCLUSIONS: A single-stage strictly transmastoid approach to otogenic encephalocele repair may be effective in patients with prior CWD mastoid cavities or requiring concurrent CWD mastoidectomy for chronic ear disease and/or cholesteatoma.

OBJECTIVE: Comparison of outcomes and billing costs of patients treated at our institution using transmastoid (TM), middle cranial fossa (MCF), and combined approaches for repair of otogenic cerebrospinal fluid (CSF) leaks and encephaloceles. STUDY DESIGN: Retrospective cohort review. SETTING: Tertiary-care hospital. PATIENTS: Seventy-seven cases of otogenic CSF leaks or encephaloceles. INTERVENTIONS: Surgical repair of an otogenic encephalocele or CSF leak using either a TM, MCF, or combined approach. MAIN OUTCOME MEASURES: Success of repair, length of operation, cost of operating room materials, postoperative need for intensive care, and postoperative length of stay. RESULTS: Forty cases (52%) were performed by the TM approach, 27 (35%) by MCF, and 10 (13%) by combined TM/MCF. Mean length of stay was not statistically different amongst TM patients (2.1 d), MCF patients (3.3 d), and combined TM/MCF patients (3.70; p = 0.112). Only 3/40 TM cases required intensive care during their admission while all MCF and combined TM/MCF approach cases were admitted to the intensive care unit for at least one night ( p < 0.001). On follow-up, CSF leak recurred in 3/77 (4%) cases: 3/27 (11%) MCF, 0/40 TM, and 0/10 combined TM/MCF patients ( p = 0.056). The mean cost of operating room materials charged to the patient was significantly greater in the MCF group ($9,883) than the TM group ($3,748; p = 0.001). CONCLUSIONS: In carefully selected patients, the TM approach is an effective and less costly alternative to MCF approaches for repair of otogenic CSF leaks and encephaloceles.
