Kaselas C, Florou M, Tsopozidi M, Spyridakis I. Acute Appendicitis Following COVID-19 Infection in Pediatric Patients: A Single Center's Study in Greece. Diagnostics (Basel) 2023; 13:2070. [PMID: 37370965 PMCID: PMC10297295 DOI: 10.3390/diagnostics13122070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 05/31/2023] [Accepted: 06/12/2023] [Indexed: 06/29/2023] Open
Abstract
PURPOSE This study investigated the potential association between the previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive infection, as well as vaccination, and the presentation of acute appendicitis in pediatric patients. It has been three years since the World Health Organization (WHO) declared the SARS-CoV-2 pandemic, and city lockdowns and self-protective measures have been applied worldwide. In an effort to contribute to the research on the probable long-term complications of the COVID-19 infection as well as the vaccination against SARS-CoV-2, the current study was designed and investigated patients' health records in the post-quarantine era. METHODS A retrospective analysis of patients admitted and treated surgically for acute appendicitis from January 2022 to June 2022 was conducted. Demographic and personal data, as well as the COVID-19 infection history of each child, were recorded. The patients who were negative for a previous COVID-19 infection were excluded. For the rest of the sample, the time-to-onset of acute appendicitis, the severity of appendicitis (complicated or uncomplicated), and the vaccination status of the patients were examined. Regarding the time-to-onset of appendicitis, we divided the patients into three groups: group A with a time-to-onset < 3 months, group B with a time-to-onset of 3-6 months, and group C with a time-to-onset of >6 months. Statistical analysis followed and was considered significant if p < 0.05. RESULTS Sixty-six children with a mean age of 10.5 years (range 1-15 years) were admitted for acute appendicitis during the determined period. After excluding 30 children that were negative for previous COVID-19 infection, we divided the patients into three groups: group A-23 children, group B-7 children, and group C-6 children. A statistically significant incidence of acute appendicitis diagnosis in <3 months after laboratory-confirmed COVID-19 infection (p < 0.01) was found. The incidence of complicated appendicitis was greater in patients with a positive SARS-CoV-2 history, with an estimated odds ratio of 1.8 (p > 0.05). The majority of the children (92%) had not received a COVID-19 vaccination. For the vaccinated children, the relative risk for complicated appendicitis was equal to 1.5 (p > 0.05). CONCLUSIONS The results of our study demonstrate a potential positive relationship between COVID-19 infection and subsequent acute appendicitis in pediatric patients. There are also some speculations on the presentation of complicated cases of appendicitis following COVID-19 infection or vaccination, but these need to be further proven. Further data are required to better understand this potential complication of COVID-19 infection as well as the role of vaccines in the current post-vaccine era.

Front Cell Infect Microbiol 2023; 13:1027769. [PMID: 37228669 PMCID: PMC10205019 DOI: 10.3389/fcimb.2023.1027769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 03/30/2023] [Indexed: 05/27/2023] Open
Abstract
Background Appendicitis is a frequent condition, with peak incidences in the second decade of life. Its pathogenesis is under debate, but bacterial infections are crucial, and antibiotic treatment remains essential. Rare bacteria are accused of causing complications, and various calculated antibiotics are propagated, yet there is no comprehensive microbiological analysis of pediatric appendicitis. Here we review different pre-analytic pathways, identify rare and common bacterial pathogens and their antibiotic resistances, correlate clinical courses, and evaluate standard calculated antibiotics in a large pediatric cohort. Method We reviewed 579 patient records and microbiological results of intraoperative swabs in standard Amies agar media or fluid samples after appendectomies for appendicitis between May 2011 and April 2019. Bacteria were cultured and identified via VITEK 2 or MALDI-TOF MS. Minimal inhibitory concentrations were reevaluated according to EUCAST 2022. Results were correlated to clinical courses. Results Of 579 analyzed patients, in 372 patients we got 1330 bacterial growths with resistograms. 1259 times, bacteria could be identified to species level. 102 different bacteria could be cultivated. 49% of catarrhal and 52% of phlegmonous appendices resulted in bacterial growth. In gangrenous appendicitis, only 38% remained sterile, while this number reduced to 4% after perforation. Many fluid samples remained sterile even when unsterile swabs had been taken simultaneously. 40 common enteral genera were responsible for 76.5% of bacterial identifications in 96.8% of patients. However, 69 rare bacteria were found in 187 patients without specifically elevated risk for complications. Conclusion Amies agar gel swabs performed superior to fluid samples and should be a standard in appendectomies. Even catarrhal appendices were only sterile in 51%, which is interesting in view of a possible viral cause. According to our resistograms, the best in vitro antibiotic was imipenem with 88.4% susceptible strains, followed by piperacillin-tazobactam, cefuroxime with metronidazole, and ampicillin-sulbactam to which only 21.6% of bacteria were susceptible. Bacterial growths and higher resistances correlate to an elevated risk of complications. Rare bacteria are found in many patients, but there is no specific consequence regarding antibiotic susceptibility, clinical course, or complications. Prospective, comprehensive studies are needed to further elicit pediatric appendicitis microbiology and antibiotic treatment.

Does Multisystem Inflammatory Syndrome Only Mimic Acute Appendicitis in Children or Can It Coexist: When Should We Suspect MIS-C? MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58081101. [PMID: 36013568 PMCID: PMC9416076 DOI: 10.3390/medicina58081101] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 08/05/2022] [Accepted: 08/12/2022] [Indexed: 11/17/2022]
Abstract
Background and Objectives: Acute abdominal pain in children has been noticed to be a primary reason to seek medical attention in multisystem inflammatory disorder (MIS-C), which can prevail separately or together with acute appendicitis. Our aim was to distinguish regular appendicitis cases from MIS-C and to suggest the best clinical and laboratory criteria for it. Materials and methods: Cases of patients, admitted to the Pediatric Surgery Department over a six-month period in 2021, were retrospectively analyzed. Confirmed MIS-C or acute appendicitis cases were selected. MIS-C cases were either separate/with no found inflammation in the appendix or together with acute appendicitis. Acute appendicitis cases were either regular cases or with a positive COVID-19 test. Four groups were formed and compared: A-acute appendicitis, B-MIS-C with acute appendicitis, C-MIS-C only and D-acute appendicitis with COVID-19. Results: A total of 76 cases were overall analyzed: A-36, B-6, C-29 and D-5. The most significant differences were found in duration of disease A—1.4 days, B—4.5 days, C—4 days, D—4 days (p < 0.0001), C reactive protein (CRP) values A-19.3 mg/L B-112.5 m/L, C-143.8 mg/L and D-141 mg/L (p < 0.0001), presence of febrile fever A-13.9%, B-66.7%, C-96.6% and D-40% (p < 0.0001) and other system involvement: A 0%, B 100%, C 100% and D 20%. A combination of these factors was entered into a ROC curve and was found to have a possibility to predict MIS-C in our analyzed cases (with or without acute appendicitis) with an AUC = 0.983, p < 0.0001, sensitivity of 94.3% and specificity of 92.7% when at least three criteria were met. Conclusions: MIS-C could be suspected even when clinical data and performed tests suggest acute appendicitis especially when at least three out of four signs are present: CRP > 55.8 mg, symptoms last 3 days or longer, febrile fever is present, and any kind of other system involvement is noticed, especially with a known prior recent COVID-19 contact, infection or a positive COVID-19 antibody IgG test.

Abstract
Acute appendicitis is a common acute surgical emergency; however, the pathogenesis of adult appendicitis remains poorly understood. The microbiome is increasingly thought to play a key role in inflammatory disease of the bowel and similarly, may play a role in appendicitis. This study aimed to characterise the microbiome of adult acute appendicitis in a prospective cohort. We recruited 60 adults with acute appendicitis and 20 healthy controls. Rectal swabs were taken from each patient. After DNA extraction, 16S rRNA amplicon sequencing was carried out for analysis of diversity and taxonomic abundance. Phylogenetic sequencing of the samples indicated that there is a difference between the microbial composition of those with acute appendicitis and healthy controls, with a statistically significant decrease in alpha diversity in rectal swabs of appendicitis patients compared to healthy controls. At the genus level, we saw an increased abundance of potential pathogens, for example, Parvimonas and Acinetobacter, and a decrease in commensal taxa such as Faecalibacterium, Blautia and Lachnospiraceae in appendicitis patients compared to healthy controls. There was a reduction in diversity and loss of commensals in the microbiome of those with acute appendicitis, which may play a role in the cascade leading to acute appendicitis or the result of this.

Abstract
Background: Although appendicitis is the most common emergency abdominal surgical pathology in the pediatric age group, there are a limited number of publications in the literature on how appendicitis has affected patients during the COVID-19 pandemic. Objectives: This study examined the effects of fear of being infected with COVID-19 and isolation measures on complications and morbidity in pediatric appendicitis cases. Methods: This study was performed in the Department of Pediatric Surgery, Faculty of Medicine, Health Sciences University, Şişli Hamidiye Etfal Training and Research Hospital, Istanbul, Turkey. Patients aged 18 years and younger who were operated on for appendicitis between 11 March 2019 and 11 May 2019 were classified as group 1, and patients aged 18 years and younger who were operated on for appendicitis between 11 March 2020 and 11 May 2020 (during the pandemic) were classified as group 2. Both groups were compared in terms of age, gender, symptoms, duration of symptoms, surgical method, duration of operation, length of hospital stay, and postoperative complications. Results: There were 85 patients in group 1 and 49 in group 2. The mean age was 11.5 ± 3.5 years in group 1 and 12.2 ± 3.0 years in group 2. While the mean hospital admission time for group 1 was 52.2 ± 38.5 hours, it was 50.2 ± 40.0 hours for group 2. The complicated appendicitis rates were 37% and 25% in group 1 and group 2, respectively. In group 1, 94.1% of the operations were completed laparoscopically, whereas, in group 2, this rate was 88.6%. The mean operation time was 64.0 ± 24.4 minutes in group 1 and 69.0 ± 33.0 minutes in group 2. The mean length of hospital stay was 2.9 ± 2.0 days in group 1 and 3.1 ± 3.40 days in group 2. The complication rate was 8.2% in group 1 and 11.4% in group 2. Conclusions: Despite the isolation measures and the risk of virus transmission, the psychosocial effects of the pandemic did not prevent real emergency cases with appendicitis from visiting hospitals.

Abstract
BACKGROUND Currently, a range of different antibiotics are administered perioperatively during appendectomy surgery in the pediatric population. One reason for the lack of a uniform treatment regimen is the paucity of large studies on microbiologic data and susceptibility patterns. METHODS A retrospective, monocentric study on antibiotic susceptibility, including 1258 pediatric patients undergoing appendectomy from 2012 to 2020 was performed. Predictors for prolonged length of stay (LOS) and complications were determined using regression analysis, and objective criteria for broad-spectrum antibiotic regimens were identified. Simulations of the effectiveness of different antibiotic regimens against identified bacterial susceptibility results were conducted. RESULTS The most important predictors for prolonged LOS and an increased incidence of infectious complications are elevated preoperative C-reactive protein levels, high intraoperative severity gradings and insufficient primary antibiotic treatment. Based on our results, a simple antibiotic treatment, consisting of cefuroxime-metronidazole (C-M) or ampicillin-sulbactam (AS), is sufficient in around 85% of all patients; both options being equally efficient. In severe appendicitis, the likelihood of resistance is 31% and 32% for C-M and AS, respectively. For piperacillin-tazobactam and C-M-tobramycin, the incidence of bacterial resistance decreases to 12%. Resistance is reduced to 8% for AS-tobramycin treatment. The patient populations benefiting most from an extended antibiotic regimen are those with a high intraoperative severity grading. CONCLUSIONS Evidence suggests that an insufficient antibiotic regimen is associated with a prolonged LOS and a higher rate of infectious complications, justifying the expansion of a simple antibiotic regimen in cases of severe intraabdominal findings. In all other cases, a simple antibiotic treatment with AS is recommended.

Abstract
BACKGROUND Acute appendicitis (AA), the most common abdominal emergency disease, is one of the most important causes of hospitalization of children. Studies have shown that white blood cell (WBC) count, mean platelet volume (MPV), C‑reactive protein (CRP), and erythrocyte sedimentation rate (ESR) can play an important role in the diagnostic prediction of appendicitis. Therefore, the aim of this study was to evaluate the diagnostic value of WBC count, polymorphonuclear leukocytes (PMNs) percentage, MPV, CRP, and ESR for the diagnosis of AA. METHODS In this study, 100 medical records were reviewed for children referred to the hospital complaining of abdominal pain and who underwent operation with a provisional diagnosis of acute appendicitis based on clinical and laboratory findings. Patients were divided into two groups according to the pathology gold standard method: AA and the other group with acute abdominal pain without appendicitis (AAP). The diagnostic accuracy of WBC, PMNs%, MPV, ESR, and CRP were compared for patients with AA and AAP. RESULTS A total of 100 patients (50 with AA and 50 with AAP) were identified. The sensitivity and specificity of WBC and PMNs% were 78 and 66%, and 76 and 54%, respectively; ESR was 80 and 48%, respectively; and CRP was 82 and 62% (30-89%), respectively. A low specificity (8%) and 70% sensitivity was calculated using the cutoff point of 8.1 fl for MPV. CONCLUSION Our data suggest that children with AA often present with significantly higher WBC count, ESR level, CRP level, PMNs%, and lower MPV level. The results of the study showed that WBC, CRP, and ESR, along with other diagnostic methods, can be useful in diagnosing AA in children. MPV is not effective in the diagnosis of AA due to its specificity; however, a significantly lower level was found in children with AA.

Abstract
BACKGROUND Appendicitis is the most common abdominal surgical emergency in children. With the rise of the Coronavirus-19 pandemic, quarantine measures have been enforced to limit the viral transmission of this disease. The purpose of this study was to identify differences in the clinical presentation and outcomes of pediatric acute appendicitis during the Coronavirus-19 pandemic. METHODS A single-institution retrospective assessment of all pediatric patients (<18 years old) with acute appendicitis from December 2019 to June 2020 was performed at a tertiary care children's hospital. Patients were divided into two groups: (1) the Pre-COVID group presented on or before March 15, 2020, and (2) the COVID group presented after March 15, 2020. Demographic, preoperative, and clinical outcomes data were analyzed. RESULTS 45 patients were included with a median age of 13 years [IQR 9.9 - 16.2] and 35 males (78%). 28 patients were in the Pre-COVID group (62%) and 17 in the COVID group (38%). There were no differences in demographics or use of diagnostic imaging. The COVID group did have a significantly delayed presentation from symptom onset (36 vs 24 hours, P < .05), higher Pediatric Appendicitis Scores (8 vs 6, P = .003), and longer hospital stays (2.2 vs 1.3 days, P = .04). There were no significant differences for rates of re-admission, re-operation, surgical site infection, perforation, or abscess formation. CONCLUSION During the Coronavirus-19 pandemic, the incidence of pediatric acute appendicitis was approximately 40% lower. These children presented in a delayed fashion with longer hospital stays. No differences were noted for postoperative complications.

Abstract
The seasonal incidence of acute abdomens, such as appendicitis, is reportedly more common in summer but is reported less frequently in Asia. Additionally, seasonal variations in the severity of acute abdomens have been evaluated insufficiently. This study evaluated the seasonal variations in the incidence and severity of acute abdomens in Japan. This retrospective observational study used a multicenter database containing data from 42 acute hospitals in Japan. We included all patients diagnosed with acute appendicitis, diverticulitis, cholecystitis, and cholangitis between January 2011 and December 2019. Baseline patient data included admission date, sequential organ failure assessment score, presence of sepsis, and disseminated intravascular coagulation. We enrolled 24,708 patients with acute abdomen. Seasonal admissions for all four acute abdominal diseases were the highest in summer [acute appendicitis, (OR = 1.35; 95% CI = 1.28-1.43); diverticulitis, (OR = 1.23; 95% CI = 1.16-1.31; cholecystitis (OR = 1.23; 95% CI = 1.11-1.36); and cholangitis (OR = 1.23; 95% CI = 1.12-1.36)]. The proportion of patients with sepsis and disseminated intravascular coagulation as well as the total SOFA score for each disease, did not differ significantly across seasons. Seasonal variations in disease severity were not observed.

Abstract
BACKGROUND Histologically normal appendices resected for right iliac fossa pain in children demonstrate immunohistochemical markers of inflammation. We aimed to establish if subclinical inflammation was present in histologically normal appendices resected from adults with right iliac fossa pain. METHODS Immunohistochemistry was performed on formalin-fixed paraffin-embedded appendices for tumour necrosis factor (TNF)-α, interleukin (IL)-6, IL-2R and serotonin in four groups: Group I (n = 120): uncomplicated appendicitis, Group II (n = 118): complicated appendicitis (perforation or gangrene), Group III (n = 104): histologically normal appendices resected for right iliac fossa pain and Group IV (n = 106) appendices resected at elective colectomy. Expression was quantified using the H-scoring system. RESULTS Median, interquartile range expression of TNF-α was increased in Groups I (5.9, 3.1-9.8), II (6.8, 3.6-12.1) and III (9.8, 6.2-15.2) when compared with Group IV (3.0, 1.4-4.7, p < 0.01). Epithelial expression of IL-6 in Groups II (44.0, 8.0-97.0) and III (71.0, 18.5-130.0) was increased when compared with Group IV (9.5, 1.0-60.2, p < 0.01). Expression of mucosal IL-2R in Groups I (47.4, 34.8-69.0), II (37.8, 25.4-60.4) and III (18.4, 10.1-34.7) was increased when compared with Group IV (2.8, 1.2-5.7, p < 0.01). Serotonin content in Groups I (3.0, 0-30.0) and II (0, 0-8.5) was decreased when compared with Groups III (49.7, 16.7-107.5) and IV (43.5, 9.5-115.8, p < 0.01). CONCLUSION Histologically normal appendices resected from symptomatic patients exhibited increased proinflammatory cytokine expression on immunohistochemistry suggesting the presence of an inflammatory process not detected on conventional microscopy.

Abstract
RATIONALE AND OBJECTIVES To determine if, during the first wave of the COVID-19 pandemic, 1) the proportion of complicated appendicitis changed, and 2) if imaging strategies for appendicitis in children changed. MATERIALS AND METHODS Retrospective cross-sectional study using administrative data from the Pediatric Health Information System, inclusive of pediatric patients diagnosed with appendicitis from March to May in 2017, 2018, 2019 and 2020. We compared trends during COVID-19 pandemic (March-May 2020) with corresponding pre-COVID-19 periods in 2017-201.9 Study outcomes were the proportion of complicated appendicitis and trends in imaging for appendicitis explained by patient-level variables. RESULTS The proportion of complicated appendicitis cases increased by 4.4 percentage points, from 46.5% pre-COVID-19 (2017-2019) to 50.9% during COVID-19 (2020), p < 0.001. Mean count of uncomplicated acute appendicitis cases decreased from pre-COVID-19 to the 2020 COVID-19 period (2017: n = 2555; 2018: n = 2679; 2019: n = 2722; 2020: n = 2231). Mean count of complicated appendicitis was unchanged between study periods (2017: n = 2189; 2018: n = 2302, 2019: n = 2442; 2020: n = 2311). Imaging approaches were largely unchanged between study periods; ultrasound was the most utilized modality in both study periods (68.3%, 70.2%; p = 0.033). CONCLUSION During the first wave of the COVID-19 pandemic, the proportion of complicated appendicitis cases increased without an absolute increase in the number of complicated appendicitis cases, but instead a decrease in the number of uncomplicated acute appendicitis diagnoses.

Abstract
BACKGROUND There is little information on the effects of Pseudomonas infection on outcomes in perforated appendicitis. As Pseudomonas is not covered by many empiric appendicitis antibiotic regiments, we hypothesized that children with Pseudomonas would have worse outcomes. METHODS Patients <18 years old undergoing appendectomy for perforated appendicitis at a tertiary children's hospital 2015-2019 were included and were stratified by presence of Pseudomonas on intraoperative culture. The primary outcome was post-operative organ-space infection (SSI). RESULTS Intraoperative cultures were collected in 58.4% of patients (n = 149/255) with 22.2% (n = 33) positive for Pseudomonas. SSIs occurred in 21.2% of children with Pseudomonas compared to 20.7% of children without Pseudomonas (p = 0.9). Children with Pseudomonas had longer antibiotic duration (9.1 vs. 6.7 days, p = 0.03) and LOS (6.7 vs. 5.9 days, p = 0.03) than those without, but a similar rate of post-operative interventions (12.2% vs. 19.0%, p = 0.4), hospital costs ($28,860 vs. $23,945, p = 0.3), ED visits (9.1% vs. 19.9%, p = 0.3), and readmissions (9.1% vs. 9.5%, p = 1). CONCLUSION Pseudomonas was identified in 22% children with perforated appendicitis and was associated with longer antibiotic durations and LOS, but similar rates of SSI, post-operative interventions, and readmissions compared to children without Pseudomonas. Empiric coverage of Pseudomonas may not be necessary.

Abstract
Background: Many problems in the diagnosis of patients with suspected appendicitis have led to the design of clinical scoring systems. In children, diagnostics tools for appendicitis are more critical. Younger patients, diagnostic challenges become more. Practical scoring systems are useful without any particular material and necessitate novel ability. Objectives: However, in spite of the reported outstanding consequences, these scoring systems are not employed regularly. Methods: In this cross-sectional study performed from October 2016 to October 2017, ten provinces out of the 31 provinces in Iran were randomly selected. A total of 631 patients referring to the hospitals with the suspicion of acute appendicitis were assessed. Related variables such as age, sex, right lower quadrant (RLQ) pain, migration of pain to RLQ, nausea, and presence of vomiting, anorexia, tenderness in RLQ and guarding, presence of rebound tenderness, and degree of fever were taken from recorded files by pediatricians. Alvarado scoring system was used for included cases to assess the accuracy of this test for diagnosis of appendicitis in our centers. Results: The mean age of eligible patients was 9.3 ± 3.21 years ranged from 3 years to 18 years, and 380 (60.5%) were male. Using the Alvarado score system in this study, considering the cut-off point value of 7 to decide for operation, the positive predictive value (PPV) showed 32.6%, and negative predictive value (NPV) was 76.73%, with a sensitivity of 44.05% and, specificity of 66.95%. There were statistically no significant correlations among the scoring of the Alvarado and diagnosis of AA (P < 0.05). Regarding receiver operator characteristic curves (ROC), the area under curve (AUC) was 0.58 (0.54 to 0.63) for Alvarado. The AUC was very low, so there was no value for the diagnosis of appendicitis. According to the findings of the present study, the cut-off point of 4.5 is suggested for the diagnosis of acute appendicitis in children with a sensitivity of 73% and specificity of 58%. Conclusions: Although the Alvarado scores supply obviously practical diagnostic information in the management of pediatric population with supposed appendicitis, this method delivers no adequate PPV for clinical practice as a safe way for determining necessary operation.

Abstract
Background: Considered vestigial from the classic point of view, the vermiform appendix has long been the subject of intensive studies. The recent understanding of appendix function in the context of unique architecture and bacterial complexity and density allows considering it as a safehouse for intestinal biodiversity. Methods: This review analyzes and assesses the current state of scientific knowledge regarding the role of the vermiform appendix in normal gut microbiota maintenance as a crucial factor of host homeostasis. It also highlights the difference in microbial composition between the large bowel and the appendix, as well as the association between the surgical excision, appendectomy, and dysbiosis-induced diseases. In addition, the review discusses the results of epidemiologic studies on appendectomy as a risk factor for the initiation of gastrointestinal carcinogenesis. It also highlights the association between appendectomy and a series of chronic inflammatory and neurologic disorders, including inflammatory bowel disease.

Abstract
BACKGROUND We describe the temporal pattern of COVID-19 admissions to a tertiary care children's hospital in central New Jersey during the SARS-CoV-2 surge, covering the time period from March 29 to July 26, 2020. METHODS Medical charts were reviewed for the date of admission, past medical history, and demographic variables, presenting signs and symptoms, admitting laboratory values, diagnostic imaging, diagnosis, treatment modalities, and outcomes including length of stay and disease severity. RESULTS Patients with symptomatic SARS-CoV-2 infection tended to present with pneumonia early during the study period, which coincided with the early surge in New Jersey cases. Approximately 2 weeks after the peak in reported SARS-CoV-2 cases in New Jersey, we began to see fewer pneumonia cases and an increase in admissions for Multi-Inflammatory Syndrome in Children and cases of acute appendicitis in association with a diagnosis of SARS-CoV-2 infection. CONCLUSIONS We present a novel association of acute appendicitis in children infected with SARS-CoV-2 and postulate that it may represent a postinfectious hyperinflammatory complication of SARS-CoV-2 infection occurring 2 weeks after the early manifestation of acute pneumonia disease in children.

Abstract
PURPOSE To evaluate the impact of the COVID-19 pandemic-related lockdown on management and outcomes of children with acute appendicitis. METHODS A retrospective cohort study was conducted, including children treated for acute appendicitis (January 20th-May 11th, 2020). The data regarding the severity of appendicitis and outcome were collected and compared for two time periods, before and after the nationwide lockdown (March 17th, 2020). RESULTS The number of cases of acute appendicitis increased by 77% during the lockdown (n = 39 vs. n = 69, p = 0.03). During the lockdown, children treated for appendicitis were older (11.1 vs. 8.9 years, p = 0.003), and were more likely to live more than 5 km away from our institution (77% vs. 52%, p = 0.017). Less children had previously consulted a general practitioner (15% vs. 33%, p = 0.028), whereas more children were transferred from other hospitals (52% vs. 31%, p = 0.043). There was no difference in terms of length of hospital stay, rate of postoperative intra-abdominal abscess, ER visits, and readmissions between both periods. Three children (4%) were diagnosed with COVID-19 and appendicitis. CONCLUSIONS Despite an increase in the number of children with appendicitis managed at our hospital during the COVID-19-related lockdown, management, and outcome remained similar. Although our pediatric center was strongly affected by this pandemic, maintaining our prior practice strategies for acute appendicitis avoided the occurrence of collateral damage for those children.

Abstract
Acute appendicitis is a common surgical emergency worldwide. Exaggerated immune responses could be associated with appendicitis. This study aimed at characterizing immune responses towards a large variety of gut commensals and pathogens, and pattern recognition receptor (PRR) ligands, and investigating the course of systemic inflammation in a prospective cohort of acute appendicitis patients. PBMC responses of 23 patients of the cohort and 23 healthy controls were characterized more than 8 months post-surgery. Serum cytokine levels were measured in 23 patients at the time of appendicitis and after one month. CRP, WBC and percentage of neutrophils were analyzed in the total cohort of 325 patients. No differences in PBMC responses were found between patients and controls. Stronger IL-10 responses were found following complicated appendicitis. A trend towards lower IL-8 responses was shown following gangrenous appendicitis. Serum IL-10 and IL-6 were significantly elevated at presentation, and IL-6, IL-8 and TNF-α levels were higher in complicated appendicitis. Routine biomarkers could predict severity of appendicitis with high specificities, but low sensitivities. Cytokine responses in patients following acute appendicitis did not differ from healthy controls. Higher serum cytokine levels were found in acute complicated and gangrenous cases. Further research into discriminative biomarkers is warranted.

Abstract
Background The association between appendectomy and multiple sclerosis (MS) is unknown. In this study, we explored the association between appendectomy and MS and neuromyelitis optica spectrum disorder (NMOSD). Patients and Methods MS and NMOSD patients older than 40 were identified from neurology records from hospitals in Malaysia. The diagnoses were based on the Revised McDonald (2010) and Wingerchuk (2015) criteria. Controls were sampled from Malaysia's normal population. Individuals were interviewed telephonically or face-to-face. The age inclusion criterion (over 40) differentiated high or low lifetime risk of appendicitis, as appendicitis incidence is rare after 40. Results 49 MS, 71 NMOSD, and 880 controls met the inclusion criteria. Seventy-two individuals (9 MS, 4 NMOSD, 59 control) had undergone appendectomy. Appendectomy rates were 18.37% in the MS group (95% CI 7.5-29.2%), 5.6% in the NMOSD group (0.3%, 11%), and 6.7% among controls (5.1%, 8.4%), (MS vs NMOSD P = 0.036, MS vs controls P = 0.007). Binary regression analysis showed that MS was an independent risk factor for appendectomy (OR 2.938, 95% CI 1.302, 6.633, P = 0.009). NMOSD showed no association with appendectomy. Conclusion MS is positively associated with appendectomy, unlike ulcerative colitis, which is negatively associated. We hypothesize that there is a commonality in the microflora in persons who have had these two illnesses.

Abstract
Complicated acute appendicitis (CAA) is a serious condition and carries significant morbidity in children. A strict diagnosis is challenging, as there are many lesions that mimic CAA. The management of CAA is still controversial. There are two options for treatment: Immediate operative management and non-operative management with antibiotics and/or drainage of any abscess or phlegmon. Each method of treatment has advantages and disadvantages. Operative management may be difficult due to the presence of inflamed tissues and may lead to detrimental events. In many cases, non-operative management with or without drainage and interval appendectomy is advised. The reasons for this approach include new medications and policies for the use of antibiotic therapy. Furthermore, advances in radiological interventions may overcome difficulties such as diagnosing and managing the complications of CAA without any surgeries. However, questions have been raised about the risk of recurrence, prolonged use of antibiotics, lengthened hospital stay and delay in returning to daily activities. Moreover, the need for interval appendectomy is currently under debate because of the low risk of recurrence. Due to the paucity of high-quality studies, more randomized controlled trials to determine the precise management strategy are needed. This review aims to study the current data on operative vs non-operative management for CAA in children and to extract any useful information from the literature.

[PMID: 31130351 DOI: 10.1016/j.jpedsurg.2019.05.001] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2019] [Revised: 05/01/2019] [Accepted: 05/06/2019] [Indexed: 12/13/2022]
Abstract
PURPOSE Interval appendectomy following nonoperative management of complicated appendicitis remains controversial. The aim of this study was to evaluate surgical pathology and clinical outcomes after pediatric interval appendectomy. METHODS Pathology results from children with complicated appendicitis who underwent interval appendectomy at a single children's hospital from 2010 to 2017 were reviewed. The primary outcome was pathology results. Secondary outcomes included complications and readmission following initial treatment and after interval appendectomy. RESULTS Among 149 patients (median age 11 years; range, 1-18), all had evidence of persistent inflammation on surgical pathology, 25 (17%) had an appendicolith, and no neoplasms were identified. Median duration of the initial admission was 8 days (range, 2-28) and 70% received a percutaneous drain prior to appendectomy. Interval appendectomy was performed at a median of 7.5 weeks (range, 2.9-29.1). Thirty-six (24%) returned to the hospital prior to their scheduled appendectomy and 6 (4%) required appendectomy earlier than planned. Nine patients (6%) experienced a complication following interval appendectomy, of which superficial surgical site infection was the most common (n = 4). CONCLUSION All children had evidence of ongoing inflammation on surgical pathology. While the clinical implications of persistent inflammation remain uncertain, these findings suggest that interval appendectomy is an appropriate treatment following medical management of complicated appendicitis in children. LEVEL OF EVIDENCE SECTION IV, Case series with no comparison groups.

Abstract
The review aims to examine the emergence and reemergence of infectious diseases in Jordan, in parallel with the Syrian refugee crisis. Qualitative approach has been adopted for systematically examining the outcomes of the Syrian crisis, which resulted in emerging and reemerging infectious diseases. It has adhered that infectious diseases, including measles, tuberculosis, and cutaneous leishmaniasis, have hazardous effects on Syrian refugees along with the local population in Jordan. The threat of major infectious diseases is higher and alarming in Jordan. National health policies should be implemented to adhere the influence of infectious diseases as well as to reduce the extent of infectious diseases in Jordan. In the 21st century, Syrian conflict can be deliberated as one of the biggest humanitarian disasters. In this multifaceted emergency with devastating requirements and limitations, it has been found essential for dominant medical healthcare providers to develop medical strategies that are based on comprehensive understanding of the concerned context and the main medical requirements and susceptible groups.

Abstract
Appendicectomy has remained the treatment of choice for appendicitis for over a century and is the most commonly performed emergency operation in children. However, emerging evidence suggests that appendicectomy may not always be necessary in uncomplicated appendicitis, with early paediatric trials demonstrating that antibiotic-only therapy can be safe and effective. Further rigorously designed and appropriately powered studies are necessarily to establish the place of non-operative management of uncomplicated appendicitis in the future.

Appendicitis Caused by Primary Varicella Zoster Virus Infection in a Child with DiGeorge Syndrome. Case Rep Pediatr 2017; 2017:6708046. [PMID: 28900551 PMCID: PMC5576433 DOI: 10.1155/2017/6708046] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2017] [Accepted: 06/11/2017] [Indexed: 12/03/2022] Open
Abstract
Introduction Chickenpox is caused by varicella zoster virus (VZV). Although predominantly a mild disease, it can cause considerable morbidity and in rare occasions even mortality in healthy children as well as increased morbidity and mortality in immunocompromised patients. The aetiology of appendicitis is largely unknown but is thought to be multifactorial. Appendicitis is a suspected, but not well documented, complication from varicella zoster virus infection. Case Presentation A five-year-old girl diagnosed with DiGeorge syndrome and a prolonged primary VZV infection was admitted due to abdominal pain, increasing diarrhoea, vomiting, and poor general condition. She developed perforated appendicitis and an intraperitoneal abscess. VZV DNA was detected by PCR in two samples from the appendix and pus from the abdomen, respectively. The child was treated with acyclovir and antibiotics and the abscess was drained twice. She was discharged two weeks after referral with no sequela. Conclusion Abdominal pain in children with viral infections can be a challenge, and appendicitis has to be considered as a complication to acute viral diseases, especially if the child is immunocompromised.

Abstract
BACKGROUND To compare the risk of complications between initial nonoperative treatment and appendectomy of uncomplicated (simple) appendicitis in children. METHODS Systematic literature search. Eligible for inclusion were both and randomized controlled trials and cohort studies including children in which the outcome of nonoperative treatment of uncomplicated appendicitis was reported with a minimum follow-up period of one year. Two authors extracted data independently and assessed quality. Primary outcome parameter was the percentage of children experiencing complications. Secondary outcomes were early failures, recurrent appendicitis and appendectomies, for all indications and on request. RESULTS Five of the 2051 articles screened were eligible for inclusion, including 147 children (nonoperative treatment) and 173 children (appendectomy) with one year follow-up. Percentage of children experiencing complications ranged from 0 to 13% versus 0-17% for nonoperative and appendectomy, respectively. Nonoperative treatment avoided an appendectomy in 62-81% of the children after one year follow-up. CONCLUSION The evidence base for initial nonoperative treatment of acute uncomplicated appendicitis in children is by far insufficient. It suggests that the percentage of patients experiencing complications in the initial nonoperative treatment group is comparable to the appendectomy group, and it may avoid an appendectomy in the large majority of children after one year follow-up. TYPE OF STUDY Systematic review. LEVEL OF EVIDENCE 1.

Abstract
PURPOSE OF REVIEW The aim of this review is to summarize the recent literature investigating nonoperative management of uncomplicated and complicated appendicitis and highlight recent data establishing its safety and efficacy. RECENT FINDINGS Recent studies and clinical trials have demonstrated the efficacy of nonoperative treatment of both uncomplicated and complicated appendicitis, defined as perforated appendicitis with or without formed abscess or phlegmon. Nonoperative management of uncomplicated appendicitis has been reported to be effective in approximately 71-94% of cases. In complicated appendicitis, treatment with antibiotics alone or antibiotics with interval appendectomy has been shown to be a well tolerated and reasonable treatment alternative. SUMMARY Appendicitis is one of the most common surgical diagnoses in children. The standard of care for many years has been surgical appendectomy; however, it carries with it risks including bleeding, wound complications, injury to surrounding structures, and the potential need for reoperation. Nonoperative management of both uncomplicated and complicated appendicitis in children is well tolerated and efficacious in select populations.

Abstract
PURPOSE Assessment of risk factors for postoperative complications following surgical treatment of pediatric perforated appendicitis (PA) is necessary to identify those patients in need of closer monitoring. In this study, we have investigated the impact of different risk factors on the occurrence of complications after an appendectomy in children with PA. MATERIAL AND METHODS The study was a retrospective, single-centre analysis of all pediatric PA conducted over a 10-year period. Preoperative clinical and laboratory results, intraoperative findings, and postoperative complications were analyzed. Risk factors were defined and a risk score was determined for postoperative complications and reinterventions. RESULTS Surgical treatment for appendicitis was performed in 840 pediatric patients during the observation period. 163 of the included patients were diagnosed with PA (mean age 8.9 ± 3.6 years). 19 (11.7%) patients developed postoperative complications, 17 (10.4%) of which required complication-related intervention. We identified five predictors of postoperative complications: the C-related protein value at admission, purulent peritonitis, open appendectomy (primary, secondary, or converted), placement of an abdominal drain, and administration of antibiotics not compliant to results from the subsequent antibiogram. The determined risk score was significantly higher in the complication group (p < .0001) and reintervention group (p < .001). CONCLUSIONS Postoperative complications following pediatric PA can be predicted using specific preoperative, intraoperative, and postoperative risk factors. In the high-risk group, an active prevention, detection, and intervention of any occurring complication is necessary and we present a new specific pediatric risk score to define patients at risk for complications.
