Electrocardiographic features of sudden unexpected death in epilepsy.

Sudden unexpected death in epilepsy (SUDEP) is the most common cause of epilepsy-related mortality. We hypothesized that electrocardiography (ECG) features may distinguish SUDEP cases from living subjects with epilepsy. Using a matched case-control design, we compared ECG studies of 12 consecutive cases of SUDEP over 10 years and 22 epilepsy controls matched for age, sex, epilepsy type (focal, generalized, or unknown/mixed type), concomitant antiepileptic, and psychotropic drug classes. Conduction intervals and prevalence of abnormal ventricular conduction diagnosis (QRS ≥110 msec), abnormal ventricular conduction pattern (QRS <110 msec, morphology of incomplete right or left bundle branch block or intraventricular conduction delay), early repolarization, and features of inherited cardiac channelopathies were assessed. Abnormal ventricular conduction diagnosis and pattern distinguished SUDEP cases from matched controls. Abnormal ventricular conduction diagnosis was present in two cases and no controls. Abnormal ventricular conduction pattern was more common in cases than controls (58% vs. 18%, p = 0.04). Early repolarization was similarly prevalent in cases and controls, but the overall prevalence exceeded that of published community-based cohorts.

Lipiodol embolism following transarterial chemoembolization: an atypical case.

OBJECTIVE: Transarterial chemoembolization is a widely used therapy for the treatment of hepatocellular carcinoma. A rare adverse event is acute respiratory distress syndrome from pulmonary embolization of Lipiodol, an iodinated oil commonly used during the procedure. The objective of this report is to describe an atypical case of acute respiratory distress syndrome from Lipiodol embolization in a patient who underwent transarterial chemoembolization for hepatocellular carcinoma 9 days prior to presentation, despite having received relatively small amounts of Lipiodol (5.5 mL). Although this diagnosis has classically been based on radiological findings, we established a diagnosis after lipid-laden macrophages were detected in bronchial alveolar lavage fluid. DESIGN: Case report. SETTING: ICU of a major metropolitan academic medical center. PATIENTS: Single case. INTERVENTIONS: Diagnostic interventions included noncontrast CT scan of the chest and cytologic examination of bronchial alveolar lavage fluid with oil red O staining. Therapeutic interventions included mechanical ventilation and methylprednisolone infusions. MEASUREMENTS AND MAIN RESULTS: Noncontrast CT demonstrated nonspecific diffuse ground glass opacification, most prominent within the upper lobes. Mechanical ventilation was begun for hypoxemic respiratory failure. Cytologic examination of bronchial alveolar lavage fluid revealed a high proportion of lipid-laden macrophages, findings consistent with Lipiodol embolism. Despite infusions of methylprednisolone, the patient expired on hospital day 8. CONCLUSIONS: Acute respiratory distress syndrome from Lipiodol embolization following transarterial chemoembolization can occur even with small Lipiodol volumes. Cytologic examination of bronchial alveolar lavage fluid with oil red O staining is a useful diagnostic modality, especially when imaging studies are equivocal.

Preventability of 30-Day Hospital Revisits Following Admission with COVID-19 at an Academic Medical Center.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic may have affected the preventability of 30-day hospital revisits, including readmissions and emergency department (ED) visits without admission. This study was conducted to examine the preventability of 30-day revisits for patients admitted with COVID-19 in order to inform the design of interventions that may decrease preventable revisits in the future. METHODS: The study team retrospectively reviewed a cohort of adults admitted to an academic medical center with COVID-19 between March 21 and June 29, 2020, and discharged alive. Patients with a 30-day revisit following hospital discharge were identified. Two-physician review was used to determine revisit preventability, identify factors contributing to preventable revisits, assess potential preventive interventions, and establish the influence of pandemic-related conditions on the revisit. RESULTS: Seventy-six of 576 COVID-19 hospitalizations resulted in a 30-day revisit (13.2%), including 21 ED visits without admission (3.6%) and 55 readmissions (9.5%). Of these 76 revisits, 20 (26.3%) were potentially preventable. The most frequently identified factors contributing to preventable revisits were related to the choice of postdischarge location and to patient/caregiver understanding of the discharge medication regimen, each occurring in 25.0% of cases. The most frequently cited potentially preventive intervention was "improved self-management plan at discharge," occurring in 65.0% of cases. Five of the 20 preventable revisits (25.0%) had contributing factors that were thought to be directly related to the COVID-19 pandemic. CONCLUSION: Although only approximately one quarter of 30-day hospital revisits following admission with COVID-19 were potentially preventable, these results highlight opportunities for improvement to reduce revisits going forward.

Uncomplicated Staphylococcus aureus Bacteremia Treatment Duration and Outcomes at an Academic Medical Center.

We compared outcomes and clinical characteristics of uncomplicated Staphylococcus aureus bacteremia planned for a 14-day or >14-day course of intravenous antibiotics. Treatment failure was infrequent in both groups (0% and 5%, respectively). Catheter-associated deep vein thrombosis, immunosuppression, and valvular dysfunction were associated with a longer planned duration of therapy.

Ifosfamide chemotherapy and nonconvulsive status epilepticus: case report and review of the literature.

We present a patient with peritoneal carcinosarcoma who was treated with the alkylating agent ifosfamide and experienced a rapid decline in mental status. Electroencephalogram (EEG) displayed generalized periodic epileptiform discharges, which raised suspicion for nonconvulsive status epilepticus (NCSE). Following administration of midazolam, the patient's clinical condition and EEG improved. We review the 8 documented cases of ifosfamide-induced NCSE, and demonstrate the similarity in clinical features when compared with ifosfamide neurotoxicity that is not classified as NCSE. EEG findings suggesting an ictal pattern are subtle and heterogeneous, but they are essential for a diagnosis. Since it is unlikely that EEGs are uniformly obtained in instances of ifosfamide neurotoxicity, many cases of NCSE may go unrecognized.
