Influenza virus is one of the most important viruses that cause the respiratory infection seasonally. In April 2009, H1N1 was detected in America and Mexico and then there was pandemic in Korea. We investigated the difference of clinical and laboratory findings between the infections of H1N1 and Influenza B.
Noroviruses (NoVs) are one major etiologic agent in acute gastroenteritis (AGE) in all ages and are the primary cause of food-borne gastroenteritis worldwide. GII-4 NoVs has predominated since 1990s, and novel recombinant strains have been reported worldwide. Researchers face difficulties in making vaccines and therapeutic agents against NoVs due t...

A total of 348 stool samples that were negative for common enteric viruses were screened for HPeV using RT-PCR. Of the 348 stool samples, seven (2.0%) were pos...
Recently, the emergence of a new NoV GII-4 variant strain every 2 or 3 years has been reported. One hundred seventeen NoV GII strains were detected by RT-PCR in children with AGE between August 2008 and February 2010. In phylogenetic analyses, GII-4 and GII-3 were the most frequently detected strains. The detection rate of the 2008 variant was simi...
Rotavirus is the most important etiological agent in children with acute gastroenteritis (AGE). The recent implementation of a rotavirus vaccine in Korea requires the monitoring of prevailing rotavirus strains in order to control the infection. One hundred thirty-nine rotavirus strains were detected in children hospitalized with AGE in Seoul, Korea...
Exploration of the genetic diversity of WU polyomavirus (WUV) has been limited in terms of the specimen numbers and particularly
the sizes of the genomic fragments analyzed. Using whole-genome sequencing of 48 WUV strains collected in four continents
over a 5-year period and 16 publicly available whole-genome sequences, we identified three main WUV...
Norovirus (NoV), a single-stranded, positive RNA virus, is an important etiologic agent of acute gastroenteritis in children worldwide. In this study, a total of 434 fecal samples collected from 434 children with acute gastroenteritis in Seoul, between September 2007 and July 2008 were tested to determine the molecular epidemiology of NoVs and char...
Human bocavirus (HBoV)-2, a new parvovirus, has been identified in stool samples and is suggested to be one of the etiologic agents of acute gastroenteritis (GE).

... More than 70% of the pediatricians in this survey reported 'sometimes' or 'almost always' in using the ROME IV criteria for diagnosing FC in children. This percentage was much higher than that reported in South Korea (16.6%) [12]. Another study which evaluated pediatrician knowledge and practice regarding diagnosis of FC in Brazil [13], the Mediterranean region [14], Argentina [15], and Saudi Arabia [3] reported that the usage of the Rome III criteria ranged 23.3-61.2%. ...

This strategy includes determination of AM in patients' peripheral blood, the criteria of pharyngitis, adenopathy, lymphocytosis ≥ 50%, and AM ≥ 10% from all lymphocytes, and has up to 75% sensitivity and up to 99% specificity depending on the study [14,15]. However, these criteria are not applicable to children as AM ≥ 10% is found in only about 50% of children with IM of EBV origin confirmed by EBV DNA positivity or anti-VCA IgM presence in peripheral blood [16][17][18]. The quantities and diagnostic value of AM in peripheral blood of children with EBV-associated IM have not been systematically studied. ...

... In one study, a 4-month probiotic supplementation reduced seizure number and improved the Quality of Life score in patients with drug-resistant epilepsy (Gómez-Eguílaz et al. 2018). The second study showed that administration of probiotics after birth may decrease rotavirus-associated seizures in neonates (Yeom et al. 2019). In animal studies, probiotics treatment reduced acute penicillin- (Kızılaslan et al. 2022) and PTZ-induced seizures (Aygun et al. 2022a;Kilinc et al. 2021), suppressed development of PTZ-induced kindling (Bagheri et al. 2019;Tahmasebi et al. 2020), ameliorated spontaneous seizures after kainic acid-induced status epilepticus , and alleviated absence seizures in WAG/Rij rats with absence epilepsy (Aygun et al. 2022b). ...

In Korea, while some studies analyzed clinical or epidemiological characteristics of HCoV-associated infection (14,(17)(18)(19), they were either single-center studies or focused on patients of all ages. Till date, there have been no multi-center studies focusing on children in Korea; hence, this study aimed to investigate the epidemiologic and clinical characteristics of HCoV-associated infections in children admitted to various hospitals in the Republic of Korea. ...

Previous studies have reported that there was no significant association between NG and the virulence factors of H. pylori, such as cagA and babA2 [34, 35] . However, the possible association between NG and environmental or host factors has not been investigated. ...
