Intraoperative neurophysiological monitoring (INM) is underutilized during the anteromesial temporal resection (AMTR) in epilepsy surgery. Herein we report a case with intraoperative capsular infarction which was early detected by INM. Among the modalities of INM, left motor evoked potentials (MEP) showed suddenly decreased amplitude of compound muscle action potentials, after the electrocoagulation in left mesial temporal areas. Postoperative neurologic and MRI findings were well correlated to the intraoperative MEP features. We also discuss the usefulness of INM during the AMTR.

Intraoperative neurophysiologic monitoring during brain tumor surgery should acquire a baseline data as soon as possible. However, motor unit potentials (MEP) in our case showed baseline data could not be acquired in the early stage of surgery, but consecutive trials had abrupt appearance of MEP just after dura opening. This case shows the acquisition of baseline MEP during brain tumor surgery should not be given up until the dura is open especially in a state of raised intracranial pressure.

Bell's palsy is the most common cause of facial paralysis with a lifetime risk of one in 60 in general population. The exact pathophysiology is unknown, but it is suspected to be associated with viral infections such as herpes simplex virus (HSV). Recurrent facial palsy is a rare condition that can be caused by various factors but the cause remains unknown. We report a case of recurrent facial palsy who had antibodies of Lyme immunoglobulin G (IgG), HSV IgG, and IgM.

Necrotizing pancreatitis is associated with high rates of morbidity and mortality. Managing necrotizing pancreatitis is challenging, and minimally invasive treatment modalities recently replaced traditional open necrosectomy. Percutaneous catheter drainage and endoscopic necrosectomy are now widely used because they are less invasive, safer, and can more effectively remove necrotic materials. Various methods and novel techniques have been introduced to manage walled-off necrosis. Herein, we report a case series of patients with necrotizing pancreatitis who were successfully treated using fully covered esophageal metal stent and endoscopic necrosectomy via the percutaneous approach. Percutaneous endoscopic necrosectomy using a fully covered esophageal stent is an effective endoscopic treatment for patients with walled-off necrosis that extends along both sides of the paracolic gutter, reduces the number of necrosectomy sessions, and improves disease status faster than conventional treatment.

PURPOSE: Status epilepticus (SE) is a pathologic state where pharmacokinetic alterations can be more pronounced and more rapid than during the other epileptic states. The consequences of such changes can exert negative influences on the timely adequate treatments for stopping uncontrolled seizures during SE. Topiramte (TPM) is one of new antiepileptic drugs with high efficacy in epilepsy, which can also be effectively used in SE. The aim of this study was to evaluate the pharmacokinetic changes during the SE by an analysis of the therapeutic drug monitoring (TDM) of TPM in patients with SE.METHODS: We retrospectively analyzed 49 serum measurements of TPM from 22 subjects with SE. The serum concentrations of TPM were measured by HPLC-tandem mass spectrometry. TDM data were categorized into malignant status epilepticus (MSE), refractory status epilepticus (RSE), and non-status epilepticus (NSE) groups. We compared concentration-to-dose ratio (CDR) among those groups.RESULTS: Among 49 cases, 11 were in MSE, 19 in RSE, and 19 in NSE. The daily dose of TPM was higher in MSE (median, interquartile range: 600, 600-800 mg) than in RSE (300, 250-600 mg) and NSE (200, 150-400 mg). The daily dose adjusted for body weight was also higher in MSE (12.2, 10.4-13.9 mg/kg) than in RSE (4.5, 3.8-12.2 mg/kg) and NSE (4.1, 2.3-7.1 mg/kg) (p<0.01). Serum concentrations of TPM were less in MSE (5.8, 4.2-7.3 mg/L) and RSE (4.9, 2.9-6.0 mg/L) than in NSE (5.5, 3.3-9.0 mg/L), which were not significantly different among the groups (p>0.1). However, the concentration-to-dose ratio (CDR) was significantly lower in MSE (0.41, 0.35-0.59 kg/L) and RSE (0.85, 0.39-1.23 kg/L) than in NSE (1.72, 0.96-2.24 kg/L) (post hoc analysis, p<0.005, 0.05).CONCLUSIONS: The serum concentrations of TPM can be influenced by SE, particularly in MSE. The higher range of dose of TPM could be needed for an adequate treatment of SE.

Objective: Many previous studies have reported relationships between particulate matter < 10 μm (PM10) and asthma in emergency department (ED) settings, but few have examined its effect on cerebrovascular diseases. We evaluate the “Lag effect” between PM10 and asthma, chronic obstructive pulmonary disease (COPD), myocardial infarction (MI), and ischemic and hemorrhagic stroke among patients that visited an ED. Methods: This study was retrospectively conducted on 96,077 patients that visited one of the 137 EDs in Seoul, Incheon, and Gyeonggi Province in South Korea in 2017. Medical information and 10th revision International Classification of Disease codes were obtained from the National Emergency Department Information System and PM10 levels from AirKorea. We used Poisson regression analysis to evaluate the lag effects of PM10 on diseases of interest. “Lag day 0” was defined as the day when PM10 > 80 μg/m3, and the PM10 values on the 5 following days were recorded. To assess the cumulative effects of PM10, we calculated relative risk (RR) by analyzing the cumulative effects over 6 days (lag days 0 to 5). Results: Asthma, COPD, and ischemic stroke patients (< 65 years old) showed a positive correlation between PM10 (asthma on lag day 5: RR, 2.587; 95% confidence interval [CI], 2.001-3.344; COPD on lag day 4: RR, 3.727; 95% CI, 2.988-4.650; and ischemic stroke on lag day 4: RR, 1.573; 95% CI, 1.168-2.118). MI in those≥65 showed the highest RR on lag day 1 (RR, 1.471; 95% CI, 1.042-2.077). Hemorrhagic stroke was not found to be significantly correlated with PM10 in either age group. Conclusion An increase in PM10 is associated with ED visits by patients<65 years old with asthma, COPD, or ischemic stroke, and with MI for those≥65 years.
