Evaluation of systemic immune-inflammation index efficacy in predicting complicated appendicitis in pediatric emergency department.

BACKGROUND: Acute appendicitis (AA) is one of the most important causes of acute abdominal pain in children who are admitted to the pediatric emergency department. This study aims to determine the usefulness of the systemic immune-inflammation index (SII) in predicting complicated appendicitis (CA) in pediatric patients. METHODS: The patients who underwent surgery with the diagnosis of AA were evaluated retrospectively. AA and control groups were formed. AA was divided into noncomplicated and CA groups. C-reactive protein (CRP), white blood cell (WBC) count, absolute neutrophil count (ANC), absolute lymphocyte count, neutrophil/lymphocyte ratio (NLR), platelet (PLT)/lymphocyte ratio (PLR), and SII values were recorded. The SII was calculated with the formula of PLT count × neutrophil/lymphocyte. The efficacy of biomarkers in predicting CA was compared. RESULTS: Our study included 1072 AA and 541 control patients. There were 74.3% of patients in the non-CA (NCA) group and 25.7% in the CA group. CRP, WBC count, ANC, NLR, PLR when AA and control group, complicated and NCA groups are compared in terms of laboratory parameters and SII level AA and it was higher in the CA group. While the SII value was 2164.91±1831.24 in the patients with NCA and 3132.59±2658.73 in those with CA (P<0.001). When the cut-off values were determined according to the area under the curve, CRP and SII were found to be the best biomarkers in predicting CA. CONCLUSION: Inflammation markers together with clinical evaluation may be useful in distinguishing noncomplicated and complicated AA. However, these parameters alone are not sufficient to predict CA. CRP and SII are the best predictors of CA in pediatric patients.

Success of the acute renal angina index in the early prediction of acute kidney injury in the emergency department.

INTRODUCTION: It is mentioned that the acute renal angina index (aRAI), a new concept, can be used in emergency departments to calculate and accurately predict the risk of developing acute kidney injury (AKI). The aims of the study included: to evaluate the predictive performance of the aRAI (AKI risk classification tool) in predicting AKI in the pediatric emergency department. METHOD: Patients who met the criteria for systemic inflammatory response syndrome were examined. AKI was defined with creatinine N1.5× baseline 24-72 hours after hospitalization. aRAI and original RAI scores were calculated for patients and were shown as renal angina positive (RA+) above a population-derived threshold. The performance of aRAI in predicting AKI compared to changes in creatinine and original RAI was evaluated. RESULTS: In total, 241 eligible subjects were enrolled. The median age of the patients was 17 months (min-max 1-192). AKI developed in 60 (24.8%) of the patients. According to the aRAI, 76 (31.5%) of 241 patients were RA(+). The aRAI had an NPV of 1.00 and an AUC of 0.948 (0.914-0.983) for the prediction of AKI. Sensitivity was 95% for the aRAI as compared to 48% for an elevation in SCr noted to be at least two times greater than the baseline while in the PED and 61% for original RAI. CONCLUSIONS: The aRAI is easily computable, does not depend on complex computational or derivation methods, and is universally accessible. We confirm and extend the findings of previous study reporting the performance of RAI for early prediction of AKI.

Benign acute childhood myositis: Factors associated with muscle symptoms and resolution.

BACKGROUND: Benign acute childhood myositis (BACM) is associated with several viral infections. The aim of this study was to evaluate the progression of myositis symptoms, laboratory findings and oseltamivir treatment in children with influenza- and non-influenza-associated BACM. METHODS: Patients aged 0-18 years old, admitted to the pediatric emergency department in the seasonal influenza period between 2018 and 2020 were retrospectively analyzed. Patients with acute onset calf tenderness, pain, difficulty in walking and elevated serum creatine phosphokinase were included and were grouped according to influenza rapid test kit results as influenza (A and B) positive, and influenza negative. The time to symptom resolution, laboratory data and the oseltamivir treatment were compared between the groups. RESULTS: There were 94 patients (67 male, 27 female) with a mean age of 77 ± 22 months. Influenza A was detected in 21, influenza B in 27, and neither were detected in 46 patients. Time to symptom resolution of BACM was shorter in the influenza-positive patients than in influenza-negative patients (2.9 ± 1.4 days and 3.5 ± 1.5 days, respectively, P = 0.027). Oseltamivir did not reduce the symptom resolution time in influenza patients. All children had normal hemoglobin and platelet counts, elevated creatine phosphokinase and 76% of them had leukopenia. Neither clinical recurrence nor metabolic disease were reported. CONCLUSION: Symptoms of BACM tended to resolve slightly earlier in influenza-positive patients and the duration of symptoms was not affected by oseltamivir treatment.

Cutaneous metastasis of bladder urothelial carcinoma; A rare conditions.

Cutaneous is an extremely rare metastatic area of bladder urothelial carcinoma. Pure cutaneous metastasis without systemic metastasis is very rare and less than ten cases have been reported in the literature. Our patient had various lymphatic fistulas to her skin due to pelvic lymphadenectomy and radiotherapy in her previous cervical cancer. We believe that the most probable mechanism underlying our patient's cutaneous metastasis is a lymphatic spread via those lymphatic fistulas. Immunotherapy is a very important option for patients who cannot receive cisplatin. This is the second case in the literature to apply immunotherapy in the setting of cutaneous metastasis of bladder cancer.

Bloody Stool: Is It Really Scary in Kids? Four Benign Cases.

Cefdinir is a third-generation oral cephalosporin used frequently in the pediatric population. The most common side effects of cefdinir are diarrhea, nausea and dyspepsia. The side effect of turning the stool color to red and giving a bloody appearance, which is alarming for both families and physicians, is very rare. In this case report, we discussed 4 cases who referred to the emergency department with bloody stool due to the use of cefdinir. The important conclusion to be drawn from this case report is to know the rare side effects of commonly used drugs such as cefdinir. This will save time and resources and prevent unnecessary interventions on the patient.

Retrospective Evaluation of Acute Headache in Pediatric Emergency Department: Etiologies, Red Flags, and Neuroimaging.

BACKGROUND: The aims of this study were to describe the etiologies of acute headache presenting to the pediatric emergency department, determine their clinical characteristics, the prevalence of red flag findings and neuroimaging and identify predictors of headaches because of serious intracranial diseases. MATERIALS AND METHODS: Patients from 2 to 18 years of age who visited pediatric emergency department with a chief complaint of headache between January 1, 2016 and August 31, 2020 were retrospectively evaluated. RESULTS: The mean age of the 558 patients included in the study was 11.17±3.78 years, and 290 (52%) were female. The most common cause of acute headache was head and neck area infections (except central nervous system infections) in 355 (63.6%) patients. Forty patients (7.2%) had a headache because of serious intracranial diseases. According to binary logistic regression analysis, the findings that predicted a serious intracranial diseases were abnormal neurological physical examination [odds ratio (OR): 187.57; 95% confidence interval (CI): 32.67-1076.64], recent onset or suddenly severe headache (OR: 14.41; 95% CI: 3.14-65.91), and vomiting (OR: 9.42; 95% CI: 1.90-46.63). Neuroimaging was performed in 63 (11.3%) patients, and 7 (1.25%) had a pathology requiring emergency treatment. CONCLUSIONS: The majority of acute headaches were evaluated as secondary headache. The most common cause of acute headache was head and neck area infections. Abnormal neurological physical examination, recent onset or suddenly severe headache, and vomiting were the most useful red flags for predicting serious intracranial diseases. The requirement for neuroimaging should be evaluated individually for each patient.

Contribution of Rapid Influenza Antigen Test to Management of Febrile Young Infants without a Focus.

BACKGROUND: The aim of this study was to evaluate the application of the rapid influenza antigen test and the contribution of the test result to patient management in febrile infants aged 29‒90 days. METHODS: The medical records of febrile infants without a focus who presented during influenza seasons from 2017‒2019 were analyzed retrospectively. The study was carried out in the Department of Pediatric Emergency, Dr. Sami Ulus Maternity and Children's Training and Research Hospital. The demographic characteristics, clinical and laboratory findings, and management of the patients were examined. The patients were divided into two groups as 'with' and 'without' testing based on whether a rapid influenza antigen test was performed or not. Test results were categorized as positive or negative. Serious bacterial infection (SBI) risk and patient management were evaluated according to test results. RESULTS: A total of 173 patients (110 males/63 females) were evaluated. The influenza test was performed in 94 (54.3%) patients, and 31.9% were positive. SBI was present in 8.7% of all patients. The mean values of white blood cell (WBC), absolute neutrophil, platelet count, C-reactive protein (CRP) and, lumbar puncture, hospitalization, and initiation of antibiotic therapy were significantly lower in the positive group compared to the negative and without testing groups (P<0.05). CONCLUSION: This study showed that using the influenza test in the emergency department in young febrile infants significantly reduced the use of antibiotics, hospitalization and the implementation of invasive procedures such as lumbar puncture, and the risk of SBI was not increased.

Evaluation of changes in pediatric emergency department utilization during COVID-19 pandemic.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic period, the use of emergency services with pediatric non-COVID patients has decreased considerably. We aimed to examine whether there was a change in the demographic data, triage profile, causes, management, and cost of pediatric emergency department (PED) visits of non-COVID patients during the pandemic period. METHODS: This study was a retrospective, single-center, observational comparative study that was conducted at the PED. Patient records were examined during "the pandemic spring" and the same period of the previous year. Patient demographics, waiting time, and outcome of the PED visit were analyzed in the entire population of children admitted to the PED during the study period, whereas more precise data such as the reason for PED use, duration of symptoms, urgency levels according to the Emergency Severity Index (ESI), final diagnosis, management, and cost of patient care were analyzed in a sample of admitted patients. We used the chi-square test, Fisher's exact test, and Mann-Whitney U test for statistical analyses. RESULTS: A total of 62,593 PED visits occurred. During the pandemic period, PED visits showed a decrease of 55.8% compared to the previous year. Patients included in the sampling study group were selected using a systematic random sampling method. The median waiting time during the pandemic period was significantly shorter than the previous year (median 14 min [IQR: 5-32] vs. median 5 min [IQR: 2-16]; p<0.001). The median duration of symptoms was 1 day (1-2) in both groups. Emergency Severity Index (ESI) levels I, II, and III showed a significant increase (27.7% vs. 37.3%) in triage scoring compared to levels IV and V (72.3% vs. 62.7%) during the pandemic period (p<0.001). The median cost per patient during the pandemic period was statistically higher compared to the previous year ($19.57 [19.57-40.50] vs. $25.34 [31.50-52.01]; p<0.001). Overall costs during the pandemic period had a 1.6-fold decline. CONCLUSION: We highlighted the changes in an ordinary PED profile during an extraordinary period. A shift in ESI levels in a more emergent direction was observed. While the number of nonurgent patients, especially those with infections, decreased, the rates of surgical cases, acute neurological and heart diseases, home accidents, and poisoning increased relative to the pre-pandemic period.

Evaluation of Epidemiological, Demographic, Clinical Characteristics and Laboratory Findings of COVID-19 in the Pediatric Emergency Department.

BACKGROUND: The aim of this study was to evaluate the epidemiological, demographic, clinical characteristics and laboratory findings of pediatric COVID-19 patients. METHODS: Patients with a positive COVID-19 nasopharyngeal polymerase chain reaction (PCR) test between 11 March 2020 and 31 December 2020 were evaluated. RESULTS: During the study period, 3118 patients underwent PCR tests, and 621 of them (19.9%) were positive. Of the patients with a positive test result, 335 were male (53.9%), the median age was 11 years. There were 308 (49.6%) patients that had a history of household exposure. The mean time between the onset of the patients complaints and the diagnosis was 1.88 ± 1.16 days. The most common symptoms were: fever (n = 424), cough (n = 419) and nasal symptoms (n = 157); loss of smell (3.5%) and taste (4.3%) were other symptoms observed in only patients aged 10 years or older. The most common abnormal laboratory finding was lymphopenia (n = 29, 36.7%). Of the 621 patients, the vast majority (n = 546, 87.9%) were classified as mild COVID-19 disease. There was a significant relationship between disease severity and age and comorbidity (p = 0.01 and p < 0.001, respectively). Only 34 patients (5.5%) were admitted to hospital, and two patients were followed-up with a diagnosis of multisystem inflammatory syndrome in children. The mortality rate was 0.32%. CONCLUSION: COVID-19 can cause different symptoms in children. Although the disease generally causes a mild clinic presentation, it should be kept in mind that it may be more severe especially in children with comorbidities.

Point-of-Care Ultrasound-Guided Versus Conventional Bladder Catheterization for Urine Sampling in Children Aged 0 to 24 Months.

OBJECTIVES: It can be difficult to obtain urine samples, especially in children aged 0 to 24 months who have not yet completed toilet training. Bladder catheterization is a common method for urine sampling in this age group. However, if the bladder is not adequately filled, this process fails and repeat catheterization is necessary. Point-of-care ultrasonography (POCUS) is often used to assist invasive procedures in the pediatric emergency department. This study aimed to compare success rates of bladder catheterization in patients with and without POCUS to guide the timing of the procedure. METHODS: This was a prospective cohort study of children 0 to 24 months presenting to a pediatric emergency department in a tertiary center hospital. Patients were divided into 2 groups; the one group received conventional catheterization (CC group) without POCUS and the other group had catheterization after POCUS (POCUS group). The transverse and anterior-posterior diameter measurements of the bladder were obtained from one view in the transverse orientation using the (6-3 MHz) convex probe. Successful catheterization was defined by obtaining 3 mL or more of urine. RESULTS: A total of 110 patients were included in the study, with 56 in the POCUS group and 54 in the CC group. There was no difference between the mean age and sex of the groups. The success rates of obtaining urine samples were 93% and 78% in the POCUS group and CC group, respectively. This difference was statistically significant (P = 0.03). No significant difference was found between measurements of bladder catheterizations with and without obtaining 3 mL or greater urine volumes in the ultrasound group (P > 0.05). CONCLUSIONS: The use of POCUS during bladder catheterization in children was found to be effective and successful. In addition, the detection of any amount of urine in the bladder using POCUS increases the success rate of bladder catheterization.

Evaluation of the accuracy of immature granulocyte percentage in predicting pediatric serious bacterial infection.

INTRODUCTION: Serious bacterial infections (SBI) are major causes of mortality and morbidity in children. The aim of this study was to determine the accuracy of the immature granulocyte (IG) percentage in predicting SBI. METHODS: Patients admitted to the pediatric emergency department with fever were divided into two groups: with SBI and with non-SBI. White blood cell (WBC) count, absolute neutrophil count (ANC), C-reactive protein (CRP), and the percentage of IG value were recorded, and their accuracy in predicting SBI was evaluated. RESULTS: Sixty-one (14.3%) patients fell into the SBI group and 367 (85.7%) were with non-SBI. Mean IG percentage among SBI patients was 0.84 ± 1.21 and 0.27 ± 0.20 for with non-SBI patients (P = .001). Based on disease, the highest IG percentage was found in patients diagnosed with sepsis (IG 3.7 ± 3.5%) and with bacterial meningitis (IG 1.6 ± 1.3%). The area under the curve (AUC) of IG percentage to predict SBI was 0.83 with 95% confidence interval (CI) [0.78-0.88]; WBC was 0.76 (95% CI 0.70-0.83); ANC was 0.73 (95% CI 0.67-0.80), and CRP was 0.79 (95% CI 0.73-0.85). When infection markers were compared to the most appropriate cut-off values in predicting SBI, IG percentage showed the highest sensitivity and specificity. When the cut-off value was determined as >0.35 for IG percentage, sensitivity was 75.4% and specificity was 76.6% in predicting SBI. CONCLUSION: Patients with SBI had a higher IG percentage. Compared to other biomarkers, IG percentage had higher sensitivity and specificity in predicting SBI.
