RESUMEN
BACKGROUND: The SARS-CoV-2 Omicron BA.2 outbreak started in Taiwan in April 2022. The pandemic posed a challenge to pediatric emergency departments (PEDs) because of increased PED visits and diverse clinical presentations. METHODS: We analyzed the clinical characteristics and impact of the Omicron BA.2 pandemic in patients who visited our PED from April 2022 to July 2022. The data from the Alpha variant pandemic during the same period in 2021 were compared with these findings. RESULTS: Overall, 10,878 children were enrolled, and 7047 (64.8%) children were positive for SARS-CoV-2 infection. They had a mean ± SD age of 5.3 ± 4.1 years. The rates of patients with Pediatric Taiwan Triage and Acuity Scale (Ped-TTAS) level 1 (most urgent) (12.3%) and level 2 (27.6%) increased. More children were triaged as most urgent during the Omicron BA.2 pandemic than during the Alpha variant pandemic (p < 0.001). Patients with SARS-CoV-2 infection were likely to present with high fever, croup, dyspnea, febrile seizures, headache, dizziness, and myalgia (all p < 0.001). Four hundred and eleven (5.8%) patients were admitted; 25 (0.4%) patients needed intensive care, including 11 (44.0%) with encephalopathy or encephalitis. Three (0.04%) patients died due to fulminant encephalitis, encephalitis with septic shock, and respiratory failure. CONCLUSIONS: The number of PED visits and the Ped-TTAS level of disease severity significantly increased during the SARS-CoV-2 Omicron BA.2 outbreak. The most common symptom was fever, and high fever was more common in patients with SARS-CoV-2 Omicron BA.2 infection. The rates of patients with croup and febrile seizures also increased.
RESUMEN
BACKGROUND: Previous studies on congenital heart diseases (CHD) associated with dextrocardia were based on selective patient databases and did not reflect the full spectrum of dextrocardia in the general population. Additionally, these studies had complex classification and presentation. Nor did these studies elaborate on the distribution of the associated CHD's complexity, the various segmental connections, and associated CHD among the four visceroatrial situs. METHODS: We retrospectively reviewed the medical records of 211 children with primary dextrocardia. We used a segmental approach to diagnose CHD. We then analyzed and compared the distribution of the above-mentioned issues among the four visceroatrial situs. RESULTS: Dextrocardia occurred most commonly with situs inversus (52.6%), followed by situs solitus (28.4%), asplenia (17.1%), and polysplenia (1.9%). Although some patients had a structurally normal heart (22.7%) or they were associated with simple CHD (17.5%), most patients had complex CHD (59.7%) consisting of a single ventricle (34.6%) or conotruncal anomaly (25.1%) (double-outlet right ventricle [7.6%], corrected transposition of the great arteries [6.2%], complete transposition of the great arteries [5.7%], tetralogy of Fallot [4.7%], etc.). Situs inversus or polysplenia had a higher prevalence of a structurally normal heart or associated with simple CHD, two patent atrioventricular (AV) valves connections, and biventricular AV connections. Situs solitus or asplenia had a higher prevalence of associated complex CHD, common AV valve connection, univentricular AV connection, pulmonary outflow tract obstruction, and anomalous pulmonary venous drainage. CONCLUSION: Our study finds that situs inversus is the most common visceroatrial situs in dextrocardia. Although some patients had a structurally normal heart or were associated with simple CHD, most patients have associated complex CHD consisting of a single ventricle or conotruncal anomaly. Dextrocardia is associated with a higher incidence of complex CHD in situs solitus and asplenia groups than in situs inversus and polysplenia groups.
RESUMEN
BACKGROUND: A surge of encephalitis was reported in children during the early wave of the omicron epidemic in Taiwan. Information on the COVID-19-associated encephalitis, including epidemiologic features and factors of unfavorable outcomes, remained unclear. METHODS: A total of 128 hospitalized Taiwanese children with laboratory-confirmed COVID-19 were enrolled between April 01, 2022, and May 31, 2022. The information on demographics and clinical features was abstracted from the medical records. Virologic lineages were determined by sequences of the spike protein. Factors associated with encephalitis and unfavorable outcomes were identified by comparisons to children without encephalitis and with favorable outcomes, respectively. RESULTS: The leading syndromes associated with COVID-19 in hospitalized children were febrile seizure (20, 15.7%), fever as the solitary symptom (18, 14.1%), and croup syndrome (14, 10.9%). Encephalitis was diagnosed in nine (7.03%) children. When compared to the three leading syndromes, children with encephalitis were at older ages, had greater rates of hypotension, PICU admissions, use of inotropic agents (P < .001 for all above comparisons), mortality (P = .008), and longer hospital stays (P = .016), but not the underlying comorbidities (P = .376). Unfavorable outcomes were identified in 3 (33.3%) of 9 encephalitis cases and associated with a lower Glasgow coma scale, hypotension, and higher C-reactive protein (P < .05 for all). BA.2.3.7 was the dominant sublineage in children with or without encephalitis. CONCLUSIONS: Omicron BA.2.3.7 can cause fulminant and lethal encephalitis in healthy children. Depressed consciousness and hypotension at presentation were significant risks of unfavorable outcomes for pediatric COVID-19-associated encephalitis.

OBJECTIVE: Factors associated with testicular torsion (TT) and consequent orchiectomy in patients presenting to pediatric emergency departments (PEDs) with scrotal pain (SP) are not well described. We report the factors predicting TT and consequent orchiectomy in children with SP. METHODS: The data on patients (aged ≤18 years) who presented with SP to PEDs at 4 branches of the Chang Gung Hospital through 10 years were analyzed. RESULTS: In all, 256 pediatric patients presented with SP. Their mean age was 11.60 ± 4.61 years and 72.7% (n = 186) were aged 10 to 18 years. The pain was left-sided in 54.7% (n = 140) and the interval between SP onset and PED arrival was 22.45 ± 31.27 hours. Overall, 84 (32.8%) patients needed surgery and 72 (28.1%) had TT. Of the patients with TT, 28 (38.9%) patients needed an orchiectomy. After analysis, TT and consequent orchiectomy were associated with a longer interval between SP onset and PED arrival, absent of testicular ultrasonic blood flow, interval between SP onset and surgery of more than 24 hours, and a high degree of TT. None of them experienced recurrent SP symptoms or TT again. CONCLUSIONS: The rate of TT in patients presenting to PEDs with an SP was 28.1%, and 38.9% of the patients with TT needed an orchiectomy. Early diagnosis and intervention helped to prevent subsequent orchiectomy in pediatric patients with TT.

BACKGROUND: To investigate Pfizer-BioNTech 162b2 mRNA COVID-19 vaccine (BNT162b2) immunization-related myocarditis and describe the risk factors for consequent hospitalization in the pediatric intensive care unit (PICU) in children between 12 and 18 years. METHODS: Children and adolescents 12 years of age and older who presented with discomfort after BNT162b2 immunization (BNTI) and visited pediatric emergency room (PER) at Chang Gung Memorial Hospital from September 22, 2021 to March 21, 2022, were included for analysis. RESULTS: 681 children presented with discomfort after BNTI and visited our PER. The mean age was 15.1 ± 1.7 years. Three hundred and ninety-four (57.9%) and 287 (42.1%) events were after 1st and 2nd dose, respectively. 58.4% (n = 398) were male. The most common complaints were chest pain (46.7%) and chest tightness (27.0%). The median (interquartile range [IQR]) interval of discomfort after BNTI was 3.0 (1.0-12.0) days. BNTI-related pericarditis, myocarditis and myopericarditis were diagnosed in 15 (2.2%), 12 (1.8%) and 2 (0.3%) patients, respectively. Eleven (1.6%) needed hospitalization in PICU. The median (IQR) hospital stay was 4.0 (3.0-6.0) days. There was no mortality. More patients were diagnosed myocarditis (p = 0.004) after 2nd dose BNTI. PICU admission occurred more commonly after 2nd dose BNTI (p = 0.007). Risk factors associated with hospitalization in PICU were abnormal EKG findings (p = 0.047) and abnormal serum troponin levels (p = 0.003) at PER. CONCLUSION: Myocarditis in children aged 12-18 years occurred more commonly following 2nd dose BNTI. Most cases were of mild or intermediate severity without death. Factors predicting BNTI-related myocarditis and consequent hospitalization in PICU were abnormal EKG findings and abnormal serum troponin levels at PER in this study.

BACKGROUND: Human adenoviruses are the most common pathogens to be isolated from cases of pediatric intussusception. However, the specific clinical characteristics of pediatric intussusception associated with adenovirus infection are poorly known. METHODS: We reviewed the medical records of pediatric patients (≤18 years of age) with intussusception treated between January 2014 and December 2020. We enrolled patients with febrile episodes, 27 with and 29 without adenovirus infections (the latter serving as control group). The demographic data, clinical characteristics, and the diagnoses and management strategies were evaluated. RESULTS: The adenovirus group exhibited a significantly longer febrile duration (4.3 ± 1.9 vs. 3.3 ± 1.1 days, p = 0.020) than the control group, with an odds ratio (OR) of 5.098 (95% confidence interval [CI] 1.223-21.254, p = 0.025). The recurrence rates were 48.1% and 13.8% in the two groups (OR 5.804; 95% CI: 1.585-21.245, p = 0.008). Most adenoviruses were non-enteric (85.2%). CONCLUSION: Adenovirus-related intussusception is associated with a longer febrile period and a higher rate of intussusception recurrence. It is recommended that patients suspected of adenovirus-related intussusception should be observed for longer than others prior to discharge.

BACKGROUND: Antibiotic treatment is indicated for infants with nontyphoidal Salmonella (NTS) enterocolitis. However, whether antimicrobial resistance (AMR) is a problem among young infants is unknown. This study investigated the characteristics of NTS infections in young infants. METHODS: Infants less than 3 months old with NTS infections were enrolled and grouped into 2 cohorts (diagnosed 2010-2015 or 2016-2021). Salmonella isolated from blood or cerebrospinal fluid was defined as invasive NTS (iNTS). The clinical features, AMR and serogroups were compared between cohorts. RESULTS: In total, 102 young infants had NTS infections, 6.9% of which were iNTS. Infants with iNTS infections were younger, hospitalized longer, and received longer antibiotic courses. More than half of cases of iNTS were resistant to ciprofloxacin, ceftriaxone and greater than or equal to 3 antibiotics. iNTS was mainly observed in Salmonella groups C2 and E. Over the past decade, group B (44%), group E (26%) and group C2 (16%) have been the most common serogroups. NTS significantly increased AMR to ciprofloxacin, ceftriaxone and trimethoprim-sulfamethoxazole, and greater than or equal to 3 antibiotics. Both multidrug resistance and extensive drug resistance in NTS also significantly increased. CONCLUSIONS: The serogroups varied with time, and the main causes of iNTS, groups C2 and E, increased over the past decade. The prevalence of AMR also increased, especially for iNTS. Given the low iNTS rate and high AMR, routine antibiotic use among infants with NTS infections between 1 and 3 months old should be reconsidered. Further large-scale research is required to formulate therapeutic strategies.

BACKGROUND: Well-appearing febrile young children discharged from the emergency department (ED) after medical assessment are still at risk for serious bacterial infections (SBI). The incidence of SBI and the effectiveness of laboratory tests in the pneumococcal conjugate vaccine era remain unknown. METHODS: We conducted a study using Taiwan's National Health Insurance claims data from 2004 to 2014. Children aged 2-24 months discharged from the ED with a diagnosis compatible with fever without source (FWS) were enrolled. RESULTS: The study identified 431,884 children from the ED with FWS. 13.53% of the children had revisits, 8.62% needed hospitalization and 1.57% developed SBI. Younger children had a higher SBI rate, but a lower revisit rate. The revisit rate was 12.22% for children aged 2-6 months, 13.61% for children aged 7-12 months and 13.77% for children aged 13-24 months (p < 0.0001). The SBI rate was 4.44% for children aged 2-6 months, 1.85% for children aged 2-6 months and 0.96% for children aged 13-24 months (p < 0.0001). Children with hemogram tests, compared to those without, had a higher revisit rate (16.30% vs. 13.15%, p < 0.0001), and a higher SBI rate in the children aged 13-24 months (1.30% vs. 0.92%, p < 0.0001); furthermore, children with urinalysis had a significantly higher revisit rate (14.42% vs. 13.24%, p < 0.0001) and higher SBI rate (2.10% vs. 1.40%, p < 0.0001). CONCLUSION: Children with FWS aged 2-24 months who were discharged from ED after blood test and urinalysis were still at risk for SBI, especially those aged 2-6 months.

Salmonella is one of the most common bacteria causing food poisoning worldwide. We evaluated the prevalence, the serotypes, and the antimicrobial resistance (AMR) of Salmonella isolates from many kinds of food, particularly pork and chicken in retail, in Taiwan between January 2017 and December 2019. The E-test was used to assess antimicrobial susceptibility and a polymerase chain reaction was performed for serotyping. A total of 459 different foods were investigated, and 117 Salmonella strains were isolated. Retail pork and chicken were the most common Salmonella-contaminated foods (64.1% and 29.1%, respectively). Of the 117 isolates, 23 serotypes were identified. The serotypes Derby (16.2%), Anatum (13.7%), and Agona (8.5%) were the most prevalent. The resistance rates to ciprofloxacin, ceftriaxone, and carbapenem were 41.9%, 11.1%, and 1.7%, respectively. The Derby and Anatum serotypes were prevalent in chicken and pork; the Anatum serotype had significantly higher ciprofloxacin and ceftriaxone resistance rates and was highly prevalent in 2017 and 2018. Multi-locus sequence typing analysis revealed that the 58 randomly chosen Salmonella isolates belonged to 18 sequence types (STs). ST64 (Anatum, 16 out of 58, 27.6%) was the most common, followed by ST321 (Muenster, 6/58, 10.3%), ST831 (Give, 5/58, 8.6%), ST155 (London, 4/58, 6.9%) and ST314 (Kentucky, 4/58, 6.9%). Multidrug-resistant Salmonella strains were remarkably observed in the serotypes Anatum (ST64) and Goldcoast (ST358). This study revealed that retail pork was commonly contaminated with antimicrobial-resistant Salmonella. Thus, periodic investigations of Salmonella serotypes and AMR are needed.
RESUMEN
Background: Previous research has pointed to the relationship between psoriasis and the development of gout. However, most previous studies had either small sample sizes or short study durations. Therefore, in this nationwide cohort study, we investigated the effect of psoriasis on the risk of gout development. Methods: The study group included one million patients from Taiwan, whom we followed for 14 years. The participants were divided into two cohorts designated as psoriasis and non-psoriasis. A 1:4 propensity score matching test was used to compare age, sex, and index year between the two cohorts. Cox proportional hazard regression was used to determine the hazard ratios (HRs) and 95% confidence intervals (CIs) for the risk of gout. Sensitivity analyses were conducted to evaluate the HR for gout after the occurrence of psoriasis. Results: The incidence densities of gout in the psoriasis and non-psoriasis cohorts were 6.96 and 5.09 per 1000 person-years, respectively. After adjusting for age, sex, urbanization, comorbidities, and nonsteroidal anti-inflammatory drug (NSAID) use, the adjusted hazard ratio (aHR) with 95% CI for incidental gout in the psoriasis group was 1.38 (1.2-1.6). Moreover, the aHR (95% CI) values for gout risk in patients with psoriasis using NSAIDs and those who did not were 1.21 (1.0-1.47) and 1.65 (1.33-2.05), respectively. Conclusion: This study demonstrated an association between psoriasis and risk of developing gout. Clinically, patients with psoriasis should be evaluated for incidental gout.
RESUMEN
Identifying ischemic ovary as a complication of ovary torsion (OT) is a significant challenge in children. This study identified risk factors for ischemic OT among pediatric OT patients to prevent delayed treatment. This retrospective study included pediatric inpatients who underwent operation for OT over 20 years. We employed multivariable logistic regression to find the risk factors associated with ischemic OT. Among the 118 patients included in this study, 78 (66.1%) had ischemic OT. Patients with ischemic OT tended to be younger; had more frequent vomiting; and had elevated White blood cell (WBC), C-Reactive protein (CRP), and segments in comparison with non-ischemic OT patients. Multivariable regression showed increased odds of ischemic ovary torsion, associated with higher WBC (12.3 × 103/mm3 vs. 8.7 × 103/mm3, p < 0.001), CRP (50.4 mg/L vs. 8.4 mg/L, p < 0.001), and vomiting (55.1% vs. 25%, p = 0.002) than in non-ischemic patients. A receiver-operating characteristic (ROC) analysis indicated that patients with vomiting, leukocytosis, or CRP ⧠40 mg/L were more likely to have ischemic OT (sensitivity, 92%; specificity, 54%; PPV, 79.6; NPV, 78.9%). Ischemic OT is common among pediatric OT patients. The presence of potential risk factors of vomiting, leukocytosis, and CRP more significant than 40 mg/L may assist clinicians in ensuring an expedited surgical treatment.
RESUMEN
PURPOSE: Antimicrobial resistance of nontyphoidal Salmonella (NTS) is a threat to public health worldwide. METHODS: A study on longitudinally collected NTS isolates from a medical center in Taiwan from 2011 to 2019 was undertaken. The multidrug resistance (MDR) and extensively drug resistance (XDR) phenotypes were determined according to internationally used definitions. Molecular serotyping was performed on the resistant NTS. RESULTS: Notably 16.1% (870/5412) of the isolates were MDR, while XDR accounted for 2.1% (111/5412). Both MDR and XDR NTS have increased significantly from 2011 to 2019, especially from 2015 to 2017 (MDR from 9.6% in 2015 to 23.1% 2017; XDR from 1.4% in 2016 to 4.7% in 2017). S. Anatum was the commonest NTS serotype expressing MDR and XDR, in 256/559 (45.8%) and 81/111 (73.0%) of the isolates, respectively, followed by S. Typhimurium and S. Goldcoast. Children < 18 years old contributed to 69.0% of all MDR cases and 64.0% of all XDR cases; majority of them aged less than 5 years. CONCLUSIONS: Increasing MDR and XDR NTS is a threat to public health. MDR and XDR NTS usually caused gastroenteritis in children < 5 years old. Multiple NTS serotypes expressing MDR and XDR indicate multiple food vehicles involved in the transmission. Proper food hygiene practice should never be over-reinforced.

BACKGROUND/PURPOSE: Salmonella Panama was considered an invasive non-typhoidal Salmonella (iNTS) serovar. Comprehensive clinical, microbiological, and genomic studies on S. Panama are scarce. We aimed to characterize the clinical and microbiological characteristics of S. Panama infection. Virulence mechanism of S. Panama and other iNTS serovars were also examined. METHODS: Based on data from the longitudinal surveillance system for Salmonella deployed in Taiwan since 2004, a case-control study was undertaken to evaluate clinical characteristics of S. Panama infection during an outbreak in 2015-2016. Cellular experiments were conducted to compare pathogenicity of S. Panama and other iNTS with S. Typhimurium. RESULTS: Most patients (41/44, 93.2%) infected by S. Panama were <5 years old (median, 1.3 years). The case-control study showed that 28 out of the 41 (68.3%) manifested as bacteremia, compared to S. Typhimurium (11.1%). Patients infected by S. Panama had longer durations of fever (P = 0.005) and hospitalization (P < 0.001). Genomic analyses split the isolates into three clades: two clones caused the outbreak, whereas another one accounted for the sporadic infections before 2015. Cellular experiments revealed that S. Panama and other iNTS serovars showed higher monolayer penetration and intracellular survival within macrophages, compared to S. Typhimurium. CONCLUSION: This study confirmed that S. Panama is a clinically invasive serovar. Different iNTS serovars express common virulence phenotypes, but they may acquire invasiveness through distinct expression or combinations of virulence genes.

Obsessive-compulsive disorder (OCD) includes a wide range of symptoms and is often associated with comorbidities. Although psychiatric involvement may be an early manifestation of Sjögren's syndrome (SS), only a few studies have demonstrated the relationship between OCD and SS. This is a nationwide cohort study identifying the risk of SS in OCD patients. We studied a longitudinal health insurance database for the period from 1999 to 2013. The study group was OCD patients with at least three outpatient visits or one hospitalization. The comparison cohort was matched by age and sex, as well as comorbidities. We calculated the risk of Sjögren's syndrome using Cox proportional hazard regression models. We performed a propensity score match for confounders and effect modifiers between the two groups. The propensity score probability was estimated through logistic regression. Primary outcome was the incidental SS. A total of 1678 patients with OCD (49% women, mean age: 35.6 years) and 3356 controls were followed up, resulting in 13,077 and 25,856 person-years, respectively. The hazard ratio for developing SS was 3.31 (95% C.I.: 1.74-6.28) in patients with OCD, compared to those without OCD after adjusting for age, sex, and comorbidities. Furthermore, the risk of SS significantly increased over the 2-year follow-up period after OCD diagnosis. We concluded that risk of SS is significantly increased in patients with OCD compared to those without OCD. Clinically, Sjögren's symptoms in OCD patients should be regularly assessed.

Non-typhoidal Salmonella (NTS) typically causes self-limiting diarrheal disease but may occasionally lead to invasive infection. This study investigated the epidemiology and antimicrobial resistance of children with NTS infection between 2012 and 2019. We retrospectively analyzed pediatric patients with NTS infections, confirmed by positive cultures, in a tertiary medical center in Taiwan in 2012 and 2019. Clinical features and laboratory data of the patients were collected. Changes in the serogroup category and antimicrobial resistance were also analyzed. Of the total 797 isolates collected, 55 had NTS bacteremia. Compared with the resistance rates in 2012, the rates of resistances to third-generation cephalosporin and ciprofloxacin were significantly higher in 2019 (4.1% vs 14.3%, P < 0.001; 1.9% vs 28.6%, P < 0.001), especially in groups B, D, and E. Moreover, we observed significantly higher antimicrobial resistance (25.3%) to third-generation cephalosporin, and approximately half the NTS isolates in the infant group were multidrug resistant - a higher rate than those of other age groups in 2019. Invasive NTS often presented with a longer fever duration, lower hemoglobin level and with no elevated C-reactive protein (P < 0.05). Non-invasive NTS isolates in 2019 were significantly more resistant to ceftriaxone (P < 0.001) and ciprofloxacin (P < 0.001) than those in 2012. The antimicrobial resistance of NTS in children has increased progressively in the past decade, and different serogroups exhibited different resistance patterns. During this period, infants showed the highest risk to get a third-generation cephalosporin-resistant NTS infection. The high rates of antimicrobial resistance among children with NTS in Taiwan merit continual surveillance.
RESUMEN
Aim: Intussusception, the most common abdominal emergency in early childhood, is frequently misdiagnosed at initial presentation. The effect of using point-of-care ultrasonography (POCUS) by emergency medicine physicians on pediatric intussusception misdiagnosis rate remains unclear. Here, we summarize outcomes and misdiagnoses before and after training junior and senior physicians on using POCUS for diagnosing intussusception and compared their performance levels. Materials and Methods: This observational cohort analysis included patients with suspected intussusception who visited a pediatric emergency department (ED) between January 2017 and December 2019. All enrolled patients were evaluated by junior (<10-year experience) or senior attending physicians. Misdiagnosis was defined as a finding of negative air reduction or confirmation of diagnosis on ED revisit or admission. The misdiagnosis rates and outcomes before and after POCUS training for intussusception diagnosis were evaluated and performance of the junior and senior physicians was compared. Results: Of the 167 enrolled patients, 130 were confirmed to have intussusception by air reduction. Misdiagnosis rate was significantly lower in the post-training patient group after training than in the pre-training patient group (43.7 vs. 12.7%, P < 0.001). After training, fewer misdiagnoses were made by the junior (59.1 vs. 25.9%, P = 0.003) and senior (31.7 vs. 0%, P < 0.001) physicians. In the post-training patient group, the door-to-reduction time and rate of ultrasonography consultation with an expert also decreased significantly (118.2 ± 124.5 vs. 198 ± 250.2 min, P = 0.006). Abdominal pain (80.9%) was the most common symptom of intussusception, followed by vomiting (58.3%), fever (17.8%), bloody stool (15.4%), and diarrhea (14.2%). Even after training, the presenting symptoms of intussusception often leading junior physicians to misdiagnosis were diarrhea and fever. Conclusions: A brief POCUS training leads to decreased misdiagnosis rates in both the senior and junior physicians. Junior physicians should increase their awareness regarding diarrhea and fever being the presenting symptoms of intussusception, particularly in early childhood. Combining clinical judgment and POCUS results forms the core principle of the evaluation of children with intussusception.
RESUMEN
BACKGROUND/PURPOSE: The FUT2 gene is a histo-blood group antigen (HBGA) that determines the susceptibility to Norovirus (NoV) infection. This study investigated the clinical significance of the FUT2 gene profile and HBGA expression in NoV infection. METHODS: Fecal specimens were collected from children in Chang-Gung Children's Hospital with acute gastroenteritis (AGE). The medical records were reviewed for clinical data. The viral etiology of gastroenteritis was validated using molecular methods. Genomic DNA was isolated from saliva or whole blood with the Puregene B Kit, according to the manufacturers' instructions. Single-nucleotide polymorphisms (SNPs) were determined by real-time PCR assays. RESULTS: FUT2 gene DNA was examined in 98 children with AGE. NoV was detected by RT-PCR in 44 patients (44.8%), while 54 (55.2%) had non-NoV AGE. Of the 44 NoV patients, 38 (86.3%) were secretors (no G428A mutation) and six (13.7%) were non-secretors (G428A mutation). Of the 54 non-NoV AGE patients, 28 (51.9%) were secretors and 20 (48.1%) were non-secretors. NoV-infected patients who were secretors had more frequent vomiting (P < 0.001), longer duration of diarrhea (P < 0.001), and greater overall disease severity score (P < 0.001) compared with non-secretors. Non-NoV infection secretor AGE patients had a longer duration of diarrhea (P < 0.001) than non-secretors. CONCLUSION: FUT2 secretor status affects NoV AGE in children.

Neonatal spinal cord injury is a rare complication of birth trauma by difficult delivery. The typical manifestations are often catastrophic, include decreased or absent movement, loss of reflexes, apnea or periodic breathing, and a lack of response to painful stimulation. The outcome is usually fatal or severe, with long-term sequelae of respiratory insufficiency, limb weakness, or even paralysis of the limbs. We described a male neonate with a C2 spinal cord injury who was born smoothly by vaginal delivery and was unnoticed initially due to unusual subtle symptoms. He presented with a hoarse voice, swallowing dysfunction, decreased movement of upper limbs, and hypercapnia. After receiving corticosteroid therapy and rehabilitation, he recovered much except that he still needed ventilator support at night.
