OBJECTIVES : The primary purpose of this study was to investigate the effects of computerized cognitive rehabilitation training on inpatients with schizophrenia in the rehabilitation unit. METHODS : Thirty-eight patients with schizophrenia from the Yongin Mental Hospital Rehabilitation Ward were randomly assigned either to a computerized cognitive rehabilitation group or to a control group. The rehabilitation group received 12 sessions of computerized cognitive rehabilitation training (Cog-Trainer) over 3 months. This training program consisted of ten units, each of which consisted of 3 levels, practice, application, and advanced. Neurocognitive functions were assessed at the beginning and end of the training period. Cognitive measures included Span of Apprehension (SPAN), Continuous Performance Test (CPT), Digit Span, Trail Making Test, and the Stroop Test. RESULTS : Compared to controls, subjects receiving computerized cognitive rehabilitation training experienced a significant improvement in attention, concentration, and working memory. CONCLUSION : These results indicate that computerized cognitive rehabilitation training can contribute to improvement in cognitive function of patients with schizophrenia. Further study to generalize these results is required.

Vascular anomalies are congenital localized abnormalities that result from improper development and maintenance of the vasculature. The lesions of vascular anomalies vary in location, type, and clinical severity of the phenotype, and the current treatment options are often unsatisfactory. Most vascular anomalies are sporadic, but patterns of inheritance have been noted in some cases, making genetic analysis relevant. Developments in the field of genomics, including next-generation sequencing, have provided novel insights into the genetic and molecular pathophysiological mechanisms underlying vascular anomalies. These insights may pave the way for new approaches to molecular diagnosis and potential disease-specific therapies. This article provides an introduction to genetic testing for vascular anomalies and presents a brief summary of the etiology and genetics of vascular anomalies.

Purpose:
Coronavirus disease 2019 (COVID-19) can be associated with neurological complications. This study investigated the impact of COVID-19 outbreaks on seizure incidence and duration in children in Korea.
Methods:
We retrospectively analyzed medical records from Kyungpook National University Children’s Hospital, including 768 children with seizures during the peak COVID-19 outbreaks in March and August 2022, and compared patterns with the same periods in 2021. We examined demographic and clinical characteristics, causes of seizures, underlying conditions, seizure durations, and COVID-19 test results.
Results:
Out of 16,373,836 COVID-19 cases during the first peak, 25.6% were children (4,184,383), and during the second peak, 20.5% of 6,400,244 cases were children (1,314,331). No significant age differences were observed between either peak and the previous year. However, when compared to the previous year, febrile seizures (FS) were more common during both peaks (25.9% vs. 65.1% in the first peak; 34.3% vs. 59.2% in the second peak). The prevalence of FS was significantly higher in the COVID-19-positive group (84.1%) than in the COVID-19-negative group (51.9%). The incidence of new-onset seizures or breakthrough seizures showed no significant difference. Seizure duration and the incidence of status epilepticus (SE) showed no significant changes, but SE was more common in the COVID-19-negative group (17.1% vs. 6.2%). The clinical features of FS were similar in both groups.
Conclusion
COVID-19 appeared to increase the risk of FS in children, but there was no significant impact on the risk of breakthrough seizures or SE in children with epilepsy. Nevertheless, larger-scale studies are necessary.

PURPOSE: There is limited data on the use of perampanel in children under 12 years of age. We evaluated the efficacy and tolerability of adjunctive perampanel treatment in children under 12 years of age with refractory epilepsy. METHODS: This retrospective observational study was performed in Kyungpook National University Hospital from July 2016 to March 2018. A responder was defined as a patient with ≥50% reduction in monthly seizure frequency compared with the baseline. Adverse events and discontinuation data were obtained to evaluate tolerability. RESULTS: Twenty-two patients (8 males, 14 females) aged 3.1–11.4 years (mean, 8.0±2.5 years) were included in this study. After an average of 9.2 months (range, 0.5–19 months) of follow-up, 15 patients (68%) showed a reduction in seizure frequency, including 5 patients (23%) with seizure freedom. The age at epilepsy onset was significantly lower (P=0.048), and the duration of epilepsy was significantly longer (P=0.019) in responders than in nonresponders. Nine patients (41%) experienced adverse events, including somnolence (23%), respiratory depression (9%), violence (4.5%), and seizure aggravation (4.5%). The most serious adverse event was respiratory depression, which required mechanical ventilation in 2 patients (9%). Eight patients (36%) discontinued perampanel due to lack of efficacy or adverse events. Three out of 4 patients (75%) who discontinued perampanel due to adverse events had an underlying medical condition. CONCLUSION: Perampanel offers a treatment option for refractory epilepsy in children. Adjunctive treatment with perampanel requires special consideration in those with underlying medical conditions to prevent serious adverse events.

Kernicterus is a neurologic syndrome, resulting from the preferential deposition of unconjugated bilirubin in the globus pallidus, subthalamus, hippocampus, and brain stem. The characteristic finding of kernicterus revealed by T2-weighted MR imaging is irreversible, bilaterally symmetrical high signal intensities in the globus pallidus. We report an atypical case of kernicterus, in which follow-up MR imaging of the globus pallidus demonstrated reversible signal intensity.

We report a case of chronic encapsulated intracerebellar hematoma occurring during infancy. An 18 month-old boy was admitted because for 3 months, his head could not be held upright, but fell to the left. Computed tomographic(CT) scanning and magnetic resonance imaging(MRI) of the brain revealed a round mass at the cerebellar vermis ; the lesion simulated a cerebellar tumor such as a medulloblastoma. The mass was surgically removed and found to be a well-encapsulated organized intracerebral hematoma. The characteristic clinical and radiologic findings and histopathologic features are discussed, and a survey of the literature is included.

We investigated the feasibility of the extracorporeal suture technique in laparoscopic pyeloplasty and laparoscopic ipsilateral ureteroureterostomy in child with ureteropelvic junction obstruction or duplex kidney. Laparoscopic pyeloplasty and laparoscopic ureteroureterostomy were performed in a child with ureteropelvic junction obstruction and in a 3-year old child with duplex kidney, respectively. Ureteropelvic junction or ureters were dissected laparoscopically and were drawn out of the abdominal cavity through the 10mm trocar tracts and subsequently anastomosed extracorporeally. We were able to draw the ureteropelvic junction or the ureters out of the abdominal cavity without difficulty owing to the laxity and thin abdominal wall in children. Operating time was 120 minutes in both cases, and all anastomses between ureter and pelvis were completed without any intraoperative complication. There was no postoperative complication. Significant improvements in urinary drainage were shown in both children on postoperative intravenous pyelogram. These early results suggest that the extracorporeal suture technique in children is feasible and easy to perform. Therefore, the drawbacks of intracorporeal suture technique during the laparoscopic pyeloplasy or ureteroureterostomy could be overcome by using this novel teehnique.

The anti-inflammatory effects of an ethanol extract of Angelica gigas (EAG) were investigated in vitro and in vivo using croton oil-induced inflammation models. Croton oil (20 microgram/mL) up-regulated mRNA expression of cyclooxygenase (COX)-I and COX-II in the macrophage cell line, RAW 264.7, resulting in the release of high concentrations of prostaglandin E2 (PGE2). EAG (1~10 microgram/mL) markedly suppressed croton oil-induced COX-II mRNA expression and PGE2 production. Application of croton oil (5% in acetone) to mouse ears caused severe local erythema, edema and vascular leakage, which were significantly attenuated by oral pre-treatment with EAG (50~500 mg/kg). Croton oil dramatically increased blood levels of interleukin (IL)-6 and PGE2 without affecting tumor-necrosis factor (TNF)-alpha and nitric oxide (NO) levels. EAG pre-treatment remarkably lowered IL-6 and PGE2, but did not alter TNF-alpha or NO concentrations. These results indicate that EAG attenuates inflammatory responses in part by blocking the COX-PGE2 pathway. Therefore, EAG could be a promising candidate for the treatment of inflammatory diseases.

KCNQ2 mutations induce a neonatal-onset epileptic encephalopathy of widely varying severity, ranging from benign familial neonatal epilepsy to severe refractory epileptic encephalopathy. Refractory seizures with KCNQ2 mutations have a positive response to sodium-channel blockers. Recently, a distinctive ictal pattern has been reported during amplitude-integrated electroencephalographic (aEEG) monitoring in infants with KCNQ2 encephalopathy. Herein, we describe a case of KCNQ2 encephalopathy with this distinctive ictal aEEG pattern, which was confirmed using conventional electroencephalography (EEG). A 3-day-old female infant presented with neonatal seizures accompanied by cyanosis and desaturation. Her seizure semiology was tonic and focal clonic. Her ictal aEEG demonstrated a sudden rise in amplitude followed by a suppressed background pattern. This pattern was also confirmed on conventional EEG. Her seizures were refractory despite the administration of multiple conventional antiepileptic drugs. Finally, c.794C>T; p. (Ala265Val) mutation was observed in the KCNQ2 gene on genetic testing, and she was diagnosed with KCNQ2 encephalopathy. Identifying this distinctive ictal pattern on aEEG monitoring facilitates the early detection of KCNQ2 encephalopathy and timely targeted treatment in patients with refractory seizures.
