Foreign body aspiration score (FOBAS)-a prospectively validated algorithm for the management and prediction of foreign body aspiration in children.

Foreign body aspiration (FBA) is a common cause of pediatric morbidity, but a standardized protocol to guide decision-making about bronchoscopy is lacking. We aimed to validate a new Foreign body aspiration score (FOBAS) for the pediatric emergency department (ED). Patients aged 0-18 years referred to the ED for suspected FBA were prospectively enrolled. FOBAS was calculated according to clinical features of a choking episode, sudden cough, exposure to nuts, absence of fever and rhinitis, stridor, and unilateral auscultatory and radiological findings. FBA risk was evaluated based on the total score (low, 1-3; moderate, 4-6; high, 7-10). Low-risk children were discharged from the ED and followed clinically. Moderate-risk children were hospitalized and evaluated by a pediatric pulmonologist, and high-risk children were referred directly for therapeutic bronchoscopy. Among the 100 enrolled children (59% males; median age 20 [interquartile range 11-39] months), a foreign body was diagnosed in 1/49 (2%), 14/41 (34.1%), and 9/10 (90%) with low, moderate, and high FOBAS, respectively (P < .001). Logistic regression indicated a higher risk for FBA with higher scores. The odds ratio for each additional point was 2.75 (95% confidence interval 1.78-4.24), and FOBAS showed a high predictive value for FBA (area under the curve 0.89). FOBAS implementation significantly reduced the rate of negative bronchoscopies, from 67.4% annually during 2016-2019 to 50% in 2020 (P = .042). CONCLUSION: FOBAS reliably predicts FBA in cases of suspected FBA and improves management and in-hospital decision-making. WHAT IS KNOWN: • Foreign body aspiration is a major cause of pediatric morbidity and mortality. • Currently, there is no unified protocol for children referred to the emergency department for suspected FBA, therefore, a well-defined algorithm is needed to improve the decision-making process. WHAT IS NEW: • The pediatric Foreign body aspiration score (FOBAS) is a new, prospectively validated clinical score that shows high sensitivity and specificity for the presence of FBA in children. • FOBAS reduces unnecessary admissions and invasive procedures and leads to better clinical outcomes.

National Weekly SARS-CoV-2 RT-PCR Screening of All Workers in Long-Term Care Facilities Associated with Decrease in Resident Mortality Rate.

INTRODUCTION: Outbreaks of COVID-19 in long-term care facilities (LTCFs) have resulted mainly from disease transmission by asymptomatic health care workers. This study examines whether routine screening tests carried out on health care workers can help in reducing COVID-19 outbreaks, morbidity, and mortality of LTCF residents. METHODS: The study followed a weekly, nationwide, government-funded screening program of LTCF personnel for SARS-CoV-2, by using reverse transcription polymerase chain reaction as the main testing technology. It included all residents and employees in Israeli LTCFs who were screened weekly during the second wave of COVID-19, during the period of time between July 13, 2020, and November 21, 2020. RESULTS: During the study period, 1,107 LTCFs were screened on a weekly basis, including 62,159 HCWs and 100,046 residents. The program screened a median of 55,282 (range 16,249, min 45,910, max 62,159) employees per week, 0.05-1.5% of which were positive for SARS-CoV-2. LTCF mortality in the first wave accounted for 45.3% of all COVID-19 deaths recorded nationally (252 of 556), and in the second wave, this ratio was reduced to 30.3% (709 of 2,337) representing a reduction of 33.8% in expected mortality (p < 0.001). A significant reduction was detected also in hospitalization rate (13.59 vs. 11.41%, p < 0.001) and elder (≥75 years old) mortality rate (52.89 vs. 41.42%, p < 0.001). 214 outbreaks in the second wave were avoided by early identification of SARS-CoV-2 positive HCWs and successful prevention of subsequent infections in the facility. CONCLUSION: Routine weekly SARS-CoV-2 RT-PCR testing of LTCF employees was associated with reduced national LTCF residents' hospitalizations and mortality rate.

Effectiveness of BNT162b2 mRNA Coronavirus Disease 2019 (COVID-19) Vaccine Against Acquisition of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Among Healthcare Workers in Long-Term Care Facilities: A Prospective Cohort Study.

BACKGROUND: We assessed vaccine effectiveness (VE) of BNT162b2 mRNA coronavirus disease 2019 (COVID-19) vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) acquisition among healthcare workers (HCWs) of long-term care facilities (LTCFs). METHODS: This prospective study, in the framework of the "Senior Shield" program in Israel, included routine weekly nasopharyngeal SARS-CoV-2 RT-PCR testing from all LTCF HCWs since July 2020. All residents and 75% of HCWs were immunized between December 2020 and January 2021. The analysis was limited to HCWs adhering to routine testing. Fully vaccinated (14+ days after second dose; n = 6960) and unvaccinated (n = 2202) HCWs were simultaneously followed until SARS-CoV-2 acquisition or end of follow-up, 11 April 2021. Hazard ratios (HRs) for vaccination versus no vaccination were calculated (Cox proportional hazards regression models, adjusting for sociodemographics and residential-area COVID-19 incidence). VE was calculated as (1- HR) × 100. RT-PCR cycle threshold (Ct) values were compared between vaccinated and unvaccinated HCWs. RESULTS: At >14 days post-second dose, 40 vaccinated HCWs acquired SARS-CoV-2 (median follow-up, 66 days; cumulative incidence, 0.6%) versus 84 unvaccinated HCWs (median follow-up, 43 days; cumulative incidence, 5.1%) (HR, .11; 95% CI, .07-.17; unadjusted VE, 89%; 95% CI, 83-93%). Adjusted VE >7 and >14 days post-second dose were similar. The median PCR Ct targeting the ORF1ab gene among 20 vaccinated and 40 unvaccinated HCWs was 32.0 versus 26.7, respectively (P value  = .008). CONCLUSIONS: VE following 2 doses of BNT162b2 against SARS-CoV-2 acquisition in LTCF HCWs was high. The lower viral loads among SARS-CoV-2-positive HCWs suggest further reduction in transmission.

The effect of the COVID-19 lockdown on children with asthma-related symptoms: A tertiary care center experience.

BACKGROUND: Acute asthma exacerbations are a common cause for emergency department (ED) visits and hospitalizations in children. Since the outbreak of coronavirus disease 2019 (COVID-19) and the education system closure/total lockdown in Israel on March 2020, we have noticed a decrease in pediatric ED visits and an increase in hospitalizations of asthma exacerbations. OBJECTIVE: to examine the patterns of ED visits for asthma exacerbations during COVID-19 outbreak, in comparison to the previous year. METHODS: A retrospective study comparing asthma related ED visits and hospitalizations among children aged 2-18 years at a tertiary center in southern Israel. Three time periods were selected: 2020 A (prelockdown, 2/1/20 to 3/14/20), 2020 B (lockdown, 3/15/20 to 5/15/20) and 2020 C (postlockdown, 5/16/20 to 6/30/20) and compared to the three parallel time periods in 2019. Data regarding demographics, number of ED visits and clinical severity parameters were collected and analyzed. RESULTS: Five hundred and twelve children visited the ED for asthma exacerbation: 273 children during 2019 and 239 children during 2020. Lockdown period in 2020 revealed significantly fewer ED visits per day compared to the parallel calendar period in 2019 (1.8 vs. 1.43, p < .001). Significantly higher hospitalization rate (47.1% vs. 33.7%, p = .05) and longer length of stay (3.15 vs. 1.9 days, p = .03) were observed during the lockdown. CONCLUSION: Lockdown is associated with fewer ED visits for asthma exacerbation, probably due to; reduced exposure to viral infections and environmental allergens, decreased availability of primary physicians and families' reluctance to arrive to the ED. ED visits during lockdown were characterized by higher hospitalization rate and longer LOS.

Diabetic Ketoacidosis at Emergency Department Presentation During the First Months of the SARS-CoV-2 Pandemic in Israel: A Multicenter Cross-Sectional Study.

INTRODUCTION: We aimed to examine the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic on diabetic ketoacidosis (DKA) rates in children with type 1 diabetes (T1D). METHODS: A retrospective cross-sectional study of 11 Israeli pediatric emergency departments (ED) was conducted. Children with T1D who attended the ED between March 1, 2020 and May 31, 2020 were compared with those who attended the ED between March 1, 2019 and May 31, 2019. RESULTS: Overall, 150 and 154 children with T1D attended the EDs during the 3-month study periods in 2020 and 2019, respectively. Among patients with established T1D, DKA rates significantly increased in 2020 compared to 2019 [38/64 (59.3%) vs 31/74 (41.9%); p < 0.043]. There was a non-statistically significant trend toward a higher rate of DKA in patients with newly diagnosed T1D [46/86 (53.4%) vs 31/80 (38.7%); p = 0.063]. No differences were observed in the rates of severe DKA in 2020 compared to 2019 among patients with established T1D [10/64 (15.6%) vs 6/74 (8.1%); p = 0.184], and newly diagnosed T1D [16/86 (18.6%) vs 14/80 (17.5%); p = 0.858]. No differences were observed in the rates of intensive care unit admissions in 2020 compared to 2019 among patients with established T1D [14/64 (21.8%) vs 14/74 (18.9%); p = 0.672], and newly diagnosed T1D [26/86 (30.2%) vs 21/80 (26.2%); p = 0.977]. CONCLUSIONS: Increased rates of DKA in children with established T1D were observed during the first 3 months of the outbreak in Israel. The findings suggest that the severity of DKA at ED presentation in children with T1D was not influenced by the pandemic.

Urine dipstick low sensitivity for UTI diagnosis in febrile infants *.

Background: Urine cultures are usually obtained from 0- to 2-month-old febrile infants, while in older children they are obtained more selectively. In 3- to 23-month-old children, urinary tract infection (UTI) diagnosis requires both positive culture and dipstick, but data are scarce regarding 0- to 2-month-old infants. We assessed dipstick performance for UTI diagnosis in 0-2 vs. 3- to 23-month-old children. Methods: A case-control study, conducted between 2015 and 2016, in southern Israel. Sensitivity and specificity of urine dipstick for diagnosing UTI were assessed. We compared dipstick false-negative (FN) and true-positive (TP) groups; high FN rate indicates low sensitivity. Results: Overall, 434 positive and 571 sterile urine culture episodes were included. Dipstick sensitivity was 63% in 0-2 month old children; 93% for supra-pubic aspiration (SPA), and ∼50% for non-SPA sampling method. However, sensitivity was >90% for 3-5 and 6- to 23-month-old children. In univariate analysis, younger age, hospitalization, lower temperature, short fever duration, lower leukocyte blood levels, neutrophils, stabs and C-reactive protein, and absent future UTI within <1 year were associated with FN compared with TP. In multivariate analysis, among positive culture episodes, age 0-2 months (odds ratio, OR = 6.60) and non-SPA sampling method (OR = 8.39) were associated with FN episodes. Conclusions: Dipstick lower sensitivity for diagnosing UTI in febrile infants 0-2 months old vs. their older counterparts, was associated with non-SPA sampling method, lower inflammatory markers, lower temperature and low risk for future UTI. This suggests that positive culture in negative dipstick episodes may not reflect a true UTI.

The Epidemiologic, Microbiologic and Clinical Picture of Bacteremia among Febrile Infants and Young Children Managed as Outpatients at the Emergency Room, before and after Initiation of the Routine Anti-Pneumococcal Immunization.

We described the occult bacteremia (OB) and bacteremia with diagnosed focus (BwF) picture among children managed as outpatients at the pediatric emergency room (PER) in southern Israel, before and after the introduction of pneumococcal conjugate vaccines (PCVs) introduction in a retrospective study enrolling all three- to 36-month-old patients with fever >38.0 °C during 2005-2014. Of 511 (0.82% of all febrile patients) true bacteremias, 230 (45%) were managed as outpatients; 96 of 230 (41.7%) had OB and 134 (3.59%) had BwF. OB and BwF rates were 0.22% and 3.02%, respectively. A significant decrease was noted in OB and BwF rates (p = 0.0008 and p = 0.02, respectively). S. pneumoniae (SP, 37.5%), K. kingae (11.4%) and Brucella spp. (8.7%) were the most common OB pathogens and SP (29.8%), S. viridans (13.4%), and Brucella spp. (12.7%) were the most common in BwF patients. PCV13 serotypes were not found among the serotypes isolated post-PCV13 introduction. During 2010-2014 there was an increase in non-PCV13 serotype isolation (p = 0.005). SP was the main pathogen isolated among patients with pneumonia, acute otitis media (AOM) and periorbital cellulitis (62.5%, 33.3% and 60%, respectively). OB and BwF decreased following the introduction of PCVs and SP was the main pathogen in both conditions. Vaccine-SP serotypes were not isolated in OB after PCV13 introduction and non-vaccine serotypes increased significantly.

Multiple hymenoptera stings in children: clinical and laboratory manifestations.

Multiple hymenoptera stings are a cause of rhabdomyolysis, elevated liver enzymes, clotting abnormalities, kidney injury, and even death. However, the progression of the clinical and laboratory findings has been described mainly in sporadic case reports. We report the clinical and laboratory manifestations of multiple hymenoptera stings in six children who were hospitalized and referred for a nephrology evaluation and follow-up over a 12-year period. One patient succumbed 13 h after the stinging accident. In the five surviving patients, we found somewhat similar pattern of clinical and laboratory course: rhabdomyolysis with elevated liver enzymes are the earliest manifestations, followed by kidney injury and anemia. An asymptomatic phase of several days between the stinging accident and severe kidney injury can occur. There was a strong seasonal association, with all six events occurring in August or September. In children with multiple hymenoptera stings, a somewhat predictable clinical and laboratory course is expected and an initial laboratory evaluation is needed, and even in asymptomatic children, a repeated laboratory evaluation is highly recommended.

Parental administration of analgesic medication in children after a limb injury.

OBJECTIVE: To document parental administration of analgesic medication to children with pain from acute limb injury before coming to the emergency department (ED). METHODS: Research assistants interviewed parents of children 0 to 18 years old who presented to the ED with acute limb injury, asking about analgesic use before arriving to the ED. Parents were also asked for personal and demographic information. Parents who did not give pharmacological analgesia were asked why they decided not to administer medications. All parents were asked if they will administer analgesia in the future. RESULTS: A total of 72% of parents administered analgesia (pharmacological or others) to their children. Only 28% of the children received pharmacological analgesics before arriving to the ED. Child's mean age was higher for the group receiving medications, compared with those not receiving medications (99 +/- 50 vs 122 +/- 52 months, respectively; P = 0.005). The main parental concern about analgesic use was of potential masking of the clinical signs and symptoms before being seen by a physician. CONCLUSIONS: Prehospital analgesic administration by parents is mainly nonpharmacological largely because of parental concern of interference with medical assessment or underestimating the child's pain. Parental concern of masking symptoms and parental perception of no pain in a child were significant factors in determining parental comfort level in using pharmacological analgesics.

Cardiac perforation 6 weeks after percutaneous atrial septal defect repair using an Amplatzer septal occluder.

A 14-year-old boy presented to the emergency department unaccompanied by his parents with a decreased level of consciousness, bradycardia, and hypotension after a syncopal episode. The patient's electronic chart revealed a percutaneous closure of a secundum atrial septal defect using an Amplatzer septal occluder (AGA Medical, Golden Valley, MN) 6 weeks before this presentation. An urgent echocardiogram revealed a moderate pericardial effusion, and 320 mL of fresh blood was evacuated by subxiphoid pericardiocentesis. The child underwent surgical exploration and was found to have a perforation in the superior-posterior aspect of the right atrium, which was corrected. The septal occluder was extracted, and the atrial septal defect was closed with a pericardial patch. This case illustrates a rare but life-threatening complication of percutaneous closure of atrial septal defect using an Amplatzer septal occluder and the importance of timely access to patient records when available history and physical examination are limited.

Acute mastoiditis in Southern Israel: a twelve year retrospective study (1990 through 2001).

BACKGROUND: Acute mastoiditis is a serious complication of acute otitis media (AOM) and has been increasingly reported in the last decade. OBJECTIVES: To report the experience accumulated with acute mastoiditis at the Soroka University Medical Center, Beer-Sheva, Israel, in a period of increasing antimicrobial resistance with Streptococcus pneumoniae. PATIENTS AND METHODS: We reviewed the records of all children with acute mastoiditis hospitalized from 1990 through 2001. Acute mastoiditis was diagnosed when one or more of the physical signs of mastoiditis (swelling, erythema, tenderness of the retroauricular area and anteroinferior displacement of the auricle) were diagnosed in the presence of concomitant or recent (< or =4 weeks) AOM. RESULTS: One hundred sixteen episodes of acute mastoiditis occurred in 101 children age 2 months to 14 years (median, 25 months; 19% <1 year old). The average yearly incidence was 6.1 cases per 100 000 population <14 years old, with a significant increase in the number of cases during the study period. Acute mastoiditis was the first evidence of AOM in 10 (10%) patients. Fever >38 degrees C and >15,000 WBC/mm3 were present in 67 and 43% of cases, respectively. Irritability, retroauricular swelling, redness and protrusion of the auricle occurred more commonly in patients <3 years old (79, 90, 84 and 76% vs. 28, 42, 45 and 30%, respectively, in patients > or =3 years old; P < 0.002). Computed tomography scans were performed in 54 of 116 (47%) cases and revealed bone destruction in 38 (70%). Periosteal abscess and lateral sinus vein thrombosis were diagnosed in 8 and 2 patients, respectively. Simple mastoidectomy was done in 32 of 116 (28%) cases, after no response to intravenous antibiotics was observed; ventilation tubes were inserted in 12 patients. Cultures were obtained at admission in 83 (72%) episodes (71 by tympanocentesis and 12 from ear discharges). Overall 43 pathogens were isolated: 34 at admission; 14 at surgery; and 5 at both occasions. The most commonly isolated organisms were S. pneumoniae (14 of 43, 33%; 4 penicillin-nonsusceptible), Streptococcus pyogenes (11 of 43, 26%), nontypable Haemophilus influenzae (6 of 43, 14%), Pseudomonas aeruginosa (5 of 43, 12%) and Escherichia coli (4 of 43, 9%). All S. pneumoniae organisms were isolated between 1996 and 2001. CONCLUSIONS: (1) The incidence of acute mastoiditis in children in Southern Israel is greater than that reported in the literature; (2) a significant increase in the number of cases was recorded during the study period; (3) the clinical picture of acute mastoiditis was more severe in infants and young children; (4) the pathogen distribution in acute mastoiditis differs from that of AOM with significantly higher rates of S. pyogenes and lower rates of nontypable H. influenzae recovery; (5) penicillin-nonsusceptible S. pneumoniae played only a minor role in the etiology of acute mastoiditis in Southern Israel.
