Optic neuritis is an inflammatory demyelinating disorder that primarily affects the optic nerve and is often associated with multiple sclerosis. While it is rare for optic neuritis to be accompanied by autoimmune encephalitis, it can occur in some cases. A 65-year-old woman with bipolar disorder presented with a progressively altered mentality.

Insomnia during coronavirus disease 2019 pandemic in Korea: a National sleep survey.

Coronavirus disease 2019 (COVID-19) pandemic has caused widespread increase in stress and affected sleep quality and quantity, with up to 30% prevalence of sleep disorders being reported after the declaration of the pandemic. This study aimed to assess perceived changes due to the pandemic in the prevalence of insomnia and excessive daytime sleepiness (EDS) in Korea, and identify the associated factors. An online survey was conducted among 4000 participants (2035 men and 1965 women) aged 20-69 years enrolled using stratified multistage random sampling according to age, sex, and residential area, between January, 2021 and February, 2022.

Sex differences in the relationship between aggression and symptoms of depression and anxiety in adults with refractory focal epilepsy.

Purpose: To determine whether sex affects the relationship between aggression and symptoms of depression and anxiety in adults with refractory focal epilepsy.

Methods: This cross-sectional study was conducted in 85 adults with refractory focal seizures, which are defined as one or more seizures recurring per month even when the patient is treated with two or more antiseizure medications. We used the Buss-Perry Aggression Questionnaire (AQ) and the Hospital Anxiety and Depression Scale (HADS) to evaluate aggression and symptoms of depression and anxiety, respectively.

Asymmetric Total Synthesis of Iheyamine B.

Herein, we report the first asymmetric total synthesis of iheyamine B from 2,2'-bisindoloazepinone using the stereoselective construction of the -vicinal 2-oxopropyl moiety in the azepine scaffold. The asymmetric decarboxylative allylic alkylation provided the α-allylated 2,2'-bisindoloazepinone intermediate. The subsequent conversion of the lactam moiety into another allyl group in a -selective manner followed by Wacker oxidation of each allyl unit to the corresponding 2-oxopropyl group completed the total synthesis of iheyamine B.

Comparisons of impulsivity among patients with different subtypes of epilepsy.

Purpose: This study assessed whether patients with epilepsy have a higher level of impulsivity than healthy controls, and compared impulsivity among patients with different subtypes of epilepsy.

Methods: The multicenter study included 108 subjects with epilepsy and 56 healthy volunteers. Subjects were evaluated by the Barratt Impulsiveness Scale-11 (BIS-11) and Patient Health Questionnaire-9, with BIS-11 scores analyzed as both dichotomized and continuous variables.

Insomnia moderates the association between recurrent seizures and emotional instability in persons with epilepsy.

Purpose: We investigated the moderating effect of sleep disturbance on the association between seizure recurrence and emotional instability in patients with epilepsy, independent of psychological distress.

Methods: This was a cross-sectional study. Patients completed the short form of the Affective Lability Scale (ALS-18), Insomnia Severity Index (ISI), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7).

Total Synthesis of Hinckdentine A.

The total synthesis of (±)-hinckdentine A is described herein. A cyanide-catalyzed imino-Stetter reaction of the aldimine derived from ethyl 2-amino-3,5-dibromocinnamate and 5-bromo-2-nitrobenzaldehyde followed by oxidative rearrangement afforded a 2,2-disubstituted 3-indolinone derivative containing the carbon skeleton and all of the functional groups present in the natural product correctly positioned, including three bromine atoms. Subsequent D-ring formation and seven-membered C-ring construction completed the total synthesis of hinckdentine A.

Lower Glucose Level Associated With Increased Risk for Post-Dural Puncture Headache.

Objective And Background: Post-dural puncture headache is the most common significant adverse event following lumbar puncture. In this study, we investigated the possible systemic factors associated with risk for post-dural puncture headache (PDPH).

Methods: We performed a retrospective cohort study in 969 patients who underwent diagnostic lumbar puncture following a standardized protocol.

Total Synthesis of Iheyamine A via the Cyanide-Catalyzed Imino-Stetter Reaction.

The total synthesis of iheyamine A from readily available ethyl 2-aminocinnamate and 5-methoxyindole-2-carboxaldehyde is described. The cyanide-catalyzed imino-Stetter reaction of an aldimine derived from ethyl 2-aminocinnamate and 5-methoxyindole-2-carboxaldehyde provided the desired unsymmetrical 2,2'-bisindole-3-acetic acid derivative. The subsequent introduction of an amino group at the C-3' position, followed by the formation of the azepine ring, completed the total synthesis of iheyamine A.

Enantioselective Synthesis of Tetrahydroquinolines from 2-Aminochalcones via a Consecutive One-Pot Reaction Catalyzed by Chiral Phosphoric Acid.

A new asymmetric protocol for the synthesis of chiral tetrahydroquinolines from 2-aminochalcones via a two-step one-pot consecutive process (cyclization/asymmetric reduction) has been developed using chiral phosphoric acid as the sole catalyst. 2-Aminochalcones were converted into the corresponding quinolines through chiral phosphoric acid-catalyzed dehydrative cyclization, and the resultant quinolines were subsequently reduced to the chiral tetrahydroquinolines via chiral phosphoric acid-catalyzed asymmetric reduction with Hantzsch ester. Various 2-aminochalcones could be applicable to this protocol, and the desired tetrahydroquinolines were obtained in excellent yields and with excellent enantioselectivities.

Chemistry of Cyanide Adducts of Aldimines from Aniline Derivatives.

The chemistry of hydrogen cyanide adducts of imines is well-developed, but that of cyanide adducts remains unexplored. This is presumably because these cyanide adducts are not stable and thus not readily available in their isolated forms. In this personal account, we present the progress made in our research program towards the development of novel organic transformations utilizing cyanide adducts of imines as key intermediates.

Synthesis of 2-Substituted Quinolines from 2-Aminostyryl Ketones Using Iodide as a Catalyst.

A new protocol for the synthesis of 2-substituted quinolines from 2-aminostyryl ketones has been developed using iodide as a nucleophilic catalyst. Conjugate addition of iodide to 2-aminostyryl ketones yielded the corresponding β-iodoketones, which could have a conformation where the amino and carbonyl groups are proximal through free rotation about the C-C single bond. Subsequent condensation between the amino and carbonyl groups followed by elimination of hydrogen iodide provided the corresponding quinolines, with regeneration of the iodide catalyst.

Intraoperative use of transcranial motor/sensory evoked potential monitoring in the clipping of intracranial aneurysms: evaluation of false-positive and false-negative cases.

Objective: Somatosensory and motor evoked potentials (SEPs and MEPs) are often used to prevent ischemic complications during aneurysm surgeries. However, surgeons often encounter cases with suspicious false-positive and false-negative results from intraoperative evoked potential (EP) monitoring, but the incidence and possible causes for these results are not well established. The aim of this study was to investigate the efficacy and reliability of EP monitoring in the microsurgical treatment of intracranial aneurysms by evaluating false-positive and false-negative cases.

High spirituality may be associated with right hemispheric lateralization in Korean adults living with epilepsy.

Purpose: Although it is known that epilepsy and spirituality are related, spirituality in epilepsy has received relatively little clinical and scientific attention. Therefore, we investigated which epilepsy-related factors are associated with high spirituality in Korean adults living with epilepsy.

Methods: This cross-sectional study was conducted in two university hospitals in Korea.

Associations between religiosity and anxiety, depressive symptoms, and well-being in Korean adults living with epilepsy.

Purpose: Religiosity can be important in the everyday life of persons with epilepsy (PWE). How PWE live with religiosity can be influenced by their cultural background. We determined whether religiosity is associated with anxiety, depressive symptoms, and well-being in Korean adults with epilepsy.

Attitudes toward epilepsy and perceptions of epilepsy-related stigma in Korean evangelical Christians.

Purpose: The scriptural description of Jesus driving out an evil spirit from a boy with epilepsy supported the idea of the spiritual nature of epilepsy for centuries. Korea has a shorter history of Christianity than the Western world. We determined whether there are differences in attitudes toward epilepsy and perception of epilepsy-related stigma between people with and without belief in evangelical Christianity in Korea.

Augmentation in restless legs syndrome patients in Korea.

Purpose: Augmentation has been known as the major complication of long-term dopaminergic treatment of restless legs syndrome (RLS). However, there have been no reports on the prevalence of augmentation in Korea. Thus, we aimed to assess the rate of augmentation and evaluate related factors in Korean RLS patients.

A case of temporal onset partial seizure induced by photic stimuli.

There are only a few case reports of photic stimulation induced partial seizures arising from the temporal lobe. A 12-year-old female with a history of three convulsions was admitted for a diagnostic evaluation. During continuous video-electroencephalogram monitoring, a complex partial seizure with secondary generalization was induced immediately after a photoparoxysmal response with a 15-Hz photic stimulation.
