ABSTRACT

Infant botulism (IB) is an intestinal toxemia that manifests as descending paralysis, constipation, and, in some cases, respiratory failure. Laboratory-confirmed IB cases are rare, and recent data in Israel are lacking. We conducted a national multicenter retrospective study of laboratory-confirmed IB cases reported in Israel during 2007-2021. A total of 8 cases were reported during the study period. During 2019-2021, incidence may have increased because of a cluster of 5 cases. Infant median age for diagnosis was 6.5 months, older than previously reported (3 months). Most cases occurred during March-July. Honey consumption was reported in 1 case, and possible environmental risk factors (living nearby rural or construction areas, dust exposure, and having a father who works as a farmer) were reported in 6 cases. Although IB is rare, its incidence in Israel may have increased over recent years, and its epidemiology and risk factors differ from cases reported previously in Israel.

ABSTRACT

BACKGROUND: Genetic aberrations in the NFκB pathway lead to primary immunodeficiencies with various degrees of severity. We previously demonstrated that complete ablation of the RelB transcription factor, a key component of the alternative pathway, results in an early manifested combined immunodeficiency requiring stem cell transplantation. OBJECTIVE: To study the molecular basis of a progressive severe autoimmunity and immunodeficiency in three patients. METHODS: Whole exome sequencing was performed to identify the genetic defect. Molecular and cellular techniques were utilized to assess the variant impact on NFκB signaling, canonical and alternative pathway crosstalk, as well as the resultant effects on immune function. RESULTS: Patients presented with multiple autoimmune progressive severe manifestations encompassing the liver, gut, lung, and skin, becoming debilitating in the second decade of life. This was accompanied by a deterioration of the immune system, demonstrating an age-related decline in naïve T cells and responses to mitogens, accompanied by a gradual loss of all circulating CD19+ cells. Whole exome sequencing identified a novel homozygous c. C1091T (P364L) transition in RELB. The P364L RelB protein was unstable, with extremely low expression, but retained some function and could be transiently and partially upregulated following Toll-like receptor stimulation. Stimulation of P364L patient fibroblasts resulted in a marked rise in a cluster of pro-inflammatory hyper-expressed transcripts consistent with the removal of RelB inhibitory effect on RelA function. This is likely the main driver of autoimmune manifestations in these patients. CONCLUSION: Incomplete loss of RelB provided a unique opportunity to gain insights into NFκB's pathway interactions as well as the pathogenesis of autoimmunity. The P364L RelB mutation leads to gradual decline in immune function with progression of severe debilitating autoimmunity.

ABSTRACT

BACKGROUND: Bartonella quintana is an important cause of culture-negative endocarditis. Although humans have been considered as its only reservoir, recent studies showed that macaque species are also reservoirs of B. quintana. Based on multi-locus sequence typing (MLST) B. quintana strains have been classified into 22 sequence types (STs), with 7 STs exclusively found in humans. Data regarding the molecular epidemiology of B. quintana endocarditis is limited to only 3 STs identified in 4 patients from Europe and Australia. We studied B. quintana endocarditis acquired in Eastern Africa or Israel to investigate the genetic diversity and clinical relatedness of B. quintana from distinct geographic regions. METHODS: Eleven patients with B. quintana endocarditis, 6 from Eastern Africa and 5 from Israel, were studied. DNA was extracted from cardiac tissue or blood specimens and analyzed by MLST based on 9 genetic loci. An evolutionary relationship between STs was visualized by a minimum spanning tree. A phylogenetic tree was constructed with the concatenated sequences (4271 bp) of the 9 loci using the maximum-likelihood method. RESULTS: Six strains were classified into previously described STs while 5 strains were identified for the first time and classified into new STs 23-27 which clustered with the previously reported STs 1-7 from human strains found in Australia, France, Germany, the USA, Russia, and the former Yugoslavia, without indication of geographical structuring. ST2 was the most prevalent ST, found in 5 of 15 patients with endocarditis (33.3%). ST26 appears to be a primary founder of the human lineage. CONCLUSIONS: The new and previously reported human STs form a single human lineage, clearly separated from the other 3 B. quintana lineages of cynomolgus, rhesus, and Japanese macaques. From evolutionary perspectives, these findings support the assumption that B. quintana has co-evolved with host species to form a host-speciation pattern. ST26 is suggested herein as a primary founder of the human lineage and may be key to explore where B. quintana had first originated; ST2 is a dominant genetic type associated with B. quintana endocarditis. To confirm these findings, additional worldwide molecular epidemiological studies are required.

ABSTRACT

BACKGROUND: The global refugee crises have raised concerns among medical communities worldwide; nonetheless, access to healthcare has rarely been studied even though refugees are a medically high-risk group. OBJECTIVES: To compare pediatric department admission rates from the pediatric emergency department (PED) of refugees and Israelis. METHODS: We compared data from refugee and Israeli children admitted to the pediatric department at Wolfson Medical Center in Israel between 2013-2017. RESULTS: A total of 104,244 patients (aged 0-18 years) came to the PED. Admission rate to the pediatric department for refugees was 695/2541 (27%) compared to 11,858/101,703 (11.7%) Israeli patients (P < 0.001). Hospital stay for patients 0-2-years of age was 3.22 ± 4.80 days for refugees vs. 2.78 ± 3.17 for Israelis (P < 0.03). Re-admission rate within 7 days was 1.3% for refugees and 2.6% for Israelis (P < 0.05). Dermatological diseases (e.g., impetigo and cellulitis) were more frequent in refugees (23.30% vs. 13.15%, P < 0.01); however, acute gastroenteritis and respiratory diagnoses were more common in Israelis (18.52% vs. 11.72%, P < 0.05 and 14.84% vs. 6.26%, P < 0.01, respectively). Neurological diseases (e.g., febrile convulsions) were also more frequent in Israelis (7.7% vs. 3%, P < 0.05). Very significantly, 23% of refugees had no healthcare coverage, while only 0.2% of the Israelis had none (P < 0.001). CONCLUSIONS: We found significant morbidity in refugees compared to the local Israeli pediatric population, highlighting the need for different approaches for each population.

ABSTRACT

AIM: The effect of reopening schools on children's contribution to SARS-CoV-2 transmission, especially within households, remains controversial. This study describes the clinical presentation of a large ambulatory COVID-19 paediatric cohort and evaluates the role of children in household transmission prior to and following school reopening. METHODS: A retrospective database cohort study was conducted in a large Health Maintenance Organization in Israel. Data of all paediatric, laboratory-confirmed Coronavirus cases between 28/2/2020 and 20/6/2020 were extracted. All cases were analysed for household contacts and primary cases within each family cluster. RESULTS: A total of 1,032 cases under 18 years old (median age 12 years) were included. Of these cases, 432 (41.9%) were asymptomatic; 122 (11.8%) cases acquired the infection at school, and 45 of them were part of two school clusters; 846 children had at least one positive household contact, in 498 family clusters, and among them, 293 primary cases were identified. Only 27 (9.2%) primary cases were under 18 years of age and six (2%) were below 10. The proportion of primary cases did not change after the re-opening of educational facilities. CONCLUSION: Children, particularly under 10 years of age, are less likely to be the vector for SARS-CoV-2 infection within household settings. Opening educational facilities did not change transmission dynamics.

ABSTRACT

AIM: Minimal data exist regarding the severity of COVID-19 in febrile infants under 60 days old. This multicentre prospective study explored the clinical course and outcomes of this hospitalised patient population, as, to date, the best approach has not been specifically addressed. METHODS: This study focused on the clinical features, laboratory parameters and outcomes of febrile infants up to 60 days old who tested positive for the virus and were hospitalised in Israel from March 2020 to January 2021. The data were extracted from a real-time prospective surveillance network for COVID-19 that includes 20 of the country's 26 hospitals. RESULTS: We identified 75 febrile young infants (60% female) with COVID-19 at a median age of 28 days (range 8-56 days). Of these, 84% had an unremarkable medical history, 29% had respiratory symptoms, and 96% had a mild illness. The Rochester criteria showed that 44% were considered at high-risk for serious bacterial infections, and we found that eight infants actually had concomitant bacterial infections. Outcomes were excellent, and no complications or fatalities were reported. CONCLUSION: The excellent outcomes of young febrile infants with COVID-19 closely resembled other respiratory viral aetiologies of fever in this age group, and there were no fatalities.

ABSTRACT

Bartonella quintana endocarditis, a common cause of culture-negative endocarditis in adults, has rarely been reported in children. We describe 5 patients 7-16 years of age from Ethiopia with heart defects and endocarditis; 4 cases were caused by infection with B. quintana and 1 by Bartonella of undetermined species. All 5 patients were afebrile and oligosymptomatic, although 3 had heart failure. C-reactive protein was normal or slightly elevated, and erythrocyte sedimentation rate was high. The diagnosis was confirmed by echocardiographic demonstration of vegetations, the presence of high Bartonella IgG titers, and identification of B. quintana DNA in excised vegetations. Embolic events were diagnosed in 2 patients. Our data suggest that B. quintana is not an uncommon cause of native valve endocarditis in children in Ethiopia with heart defects and that possible B. quintana infection should be suspected and pursued among residents of and immigrants from East Africa, including Ethiopia, with culture-negative endocarditis.

ABSTRACT

BACKGROUND: Nebulized hypertonic saline (HS) treatment is unavailable to large populations worldwide. OBJECTIVES: To determine the bacterial contamination and electrolyte concentrations in homemade (HM-HS) vs. pharmacy made (PM-HS). METHODS: We conducted three double-blind consecutive trials: 50 boiled-water homemade 3%-HS (B-HM-HS) bottles and 50 PM-HS. The bottles were cultured after 48 hours. Electrolyte concentrations were measured in 10 bottles (5 per group). Forty bottles (20 per group) were distributed to volunteers for simulation of realistic treatment by drawing 4 ml HS three times daily. From each bottle, 4 ml samples were cultured after 1, 5, and 7 days. Volunteers prepared 108 bottles containing 3%-HS, sterilizing them using a microwave oven (1100-1850W). These bottles were cultured 24 hours, 48 hours, and 1 month after preparation. RESULTS: Contamination rates of B-HM-HS and PM-HS after 48 hours were 56% and 14%, respectively (P = 0.008). Electrolyte concentrations were similar: 3.7% ± 0.4 and 3.5% ± 0.3, respectively (P = NS). Following a single day of simulation B-HM-HS bottles were significantly more contaminated than PM-HS bottles: 75% vs. 20%, respectively (P < 0.01). By day 7, 85% of PM-HS bottles and 100% of B-HM-HS bottles were contaminated (P = 0.23). All 108 microwave-oven prepared bottles (MICRO-HS) were sterile, which was significantly better than the contamination rate of B-HM-HS and PM-HS (P < 0.001). Calculated risk for a consecutive MICRO-HS to be infected was negligible. CONCLUSIONS: Microwave preparation provides sterile HS with adequate electrolyte concentrations, and is a cheap, fast, and widely available method to prepare HS.

ABSTRACT

Israel is a relatively rapidly growing country with a high fertility rate and a young population. These data emphasize the importance of an efficient and appropriate pediatric service for its population. Although the pediatric service in Israel has attained several achievements, such as a relatively low infant mortality, high vaccination rates, and a primary care service that is mainly based on licensed pediatricians, several challenges, such as overcoming inequalities in health care and health indices between different regions and different populations within the country and the provision of a more organized mental and dental health care service to children, need to be addressed.

ABSTRACT

BACKGROUND: During 2013-2014 Israel experienced a continuous circulation of wild poliovirus type 1 (WPV1) but with no clinical cases. WPV1 circulation was gradually terminated following a national vaccination campaign of bivalent oral poliovirus vaccine (bOPV) for 943,587 children < 10 years. Four cases of children with neurological manifestations that appeared following bOPV vaccinations were reported during the campaign: three of Guillain-Barré syndrome (GBS) and one of acute disseminated encephalomyelitis (ADEM). OBJECTIVES: To present an analysis of these cases, the rapid response and the transparent publication of the results of this analysis. METHODS: The clinical, laboratory and epidemiological data of these four patients were available during the analysis. In addition, data regarding the incidence of GBS and ADEM during previous years, and reported cases of acute flaccid paralysis (AFP) and the incidence of Campylobacter jejuni enteritis were collected from the Epidemiology Department of the Israel Ministry of Health. RESULTS: The incidence of GBS among bOPV-vaccinated children was not higher than among bOPV-unvaccinated children. For all the cases reviewed the "incubation period" from vaccination to the event was longer than expected and other more plausible causes for the neurologic manifestations were found. There is no evidence in the literature of a causal relationship between bOPV and ADEM. CONCLUSIONS: There was no association between the bOPV vaccine and the reported neurological manifestations. We believe that our experience may assist other public health professionals when confronting a similar problem of alleged side effects during a mass medical intervention.

ABSTRACT

AIM: The precise role of the influenza virus in the morbidity of hospitalised paediatric pneumonia cases is unknown. We identified how many cases hospitalised during the 2009 pandemic had influenza-associated pneumonia and assessed their severity. METHODS: Children admitted to three Israeli medical centres during the 2009 influenza pandemic with radiologically confirmed pneumonia were prospectively screened for influenza. We compared the clinical, laboratory and radiologic findings for positive and negative cases. RESULTS: The pandemic H1N1 virus was detected in 89 (30%) of the 297 patients hospitalised for pneumonia and 55% of the Paediatric Intensive Care Unit admissions for pneumonia. There were no significant differences in the rates of underlying disease between the two groups. Logistic regression analysis revealed that children with pandemic H1N1 virus-associated pneumonia had significantly increased disease severity than those without, with a higher incidence of hypoxemia (41.6% versus 24%) with a relative risk (RR) of 2.2, higher rate of paediatric intensive care unit admission (16.9% versus 5.8%, RR of 2.7) and higher rate of mechanical ventilation (10.1% versus 2.4%, RR:4.4). CONCLUSION: During the 2009 influenza pandemic, 30% of children hospitalised for pneumonia had the influenza infection and these children displayed increased disease severity.

ABSTRACT

Wild poliovirus type 1 (WPV1) introduction into southern Israel in early 2013 was detected by routine environmental surveillance. The virus was identified genetically as related to the South Asian (SOAS) R3A lineage endemic to Pakistan in 2012. Intensified, high-throughput environmental surveillance using advanced molecular methods played a critical role in documenting and locating sustained transmission throughout 2013 and early 2014 in the absence of any acute flaccid paralysis. It guided the public health responses, including stool-based surveillance and serosurveys, to determine the point prevalence in silent excretors and measured the effect of vaccination campaigns with inactivated polio vaccine and bivalent oral polio vaccine on stopping transmission.

ABSTRACT

BACKGROUND: Despite the increasing rates of carbapenem-resistant Acinetobacter baumannii (CRAB) carriage among hospitalized patients in endemic settings, the role of active surveillance cultures and cohorting is still debated. We sought to determine the long-term effect of a multifaceted infection-control intervention on the incidence of CRAB in an endemic setting. METHODS: A prospective, quasi-experimental study was performed at a 670-bed, acute-care hospital. The study consisted of 4 phases. In phase I, basic infection control measures were used. In phase II, CRAB carriers were cohorted in a single ward with dedicated nursing and enhanced environmental cleaning. In phase III large-scale screening in high-risk units was implemented. Phase IV comprised a 15-month follow-up period. RESULTS: During the baseline period, the mean incidence rate (IDR) of CRAB was 44 per 100,000 patient days (95% CI, 37.7-54.1). No significant decrease was observed during phase II (IDR, 40.8 per 100,000 patient days; 95% CI, 30.0-56.7; P = .97). During phase III, despite high compliance with control measures, ongoing transmission in several wards was observed and the mean IDR was 53.9 per 100,000 patient days (95% CI, 40.5-72.2; P = .55). In phase IV, following the implementation of large-scale screening, a significant decrease in the mean IDR was observed (25.8 per 100,000 patient days; 95% CI, 19.9-33.5; P = .03). An overall reduction of CRAB rate was observed between phase I and phase IV (rate ratio, 0.6; 95% CI, 0.4-0.9; P < .001). CONCLUSIONS: The comprehensive intervention that included intensified control measures with routine active screening cultures was effective in reducing the incidence of CRAB in an endemic hospital setting.

ABSTRACT

BACKGROUND: Candidemia is a serious complication in pediatric patients with congenital heart defects (CHD) after cardiac surgery. Information about the epidemiology, clinical characteristics and risk factors for candidemia in this vulnerable population remains limited. METHODS: This retrospective case-control study was conducted in 2 pediatric intensive care units between 2004 and 2019. All patients <18 years old who developed candidemia following cardiac surgery were included. Each case was matched with 2 control patients based on age and date of surgery. Multivariable logistic regression analysis was conducted to determine the risk factors for postoperative candidemia. RESULTS: Thirty-five candidemia cases were identified and matched to 70 control cases. The incidence of candidemia was 6.3 episodes per 1000 admissions. The median age for candidemia cases was 4 months. The attributable mortality was 28.5%. The predominant (54%) pathogens isolated were non- albicans Candida species, of which C. parapsilosis isolates demonstrated high resistance to fluconazole (70%). Independent risk factors associated with candidemia included cumulative antibiotic exposure for ≥4 days [OR: -4.3; 95% confidence interval (CI): 1.3-14.6; P = 0.02], the need for total parenteral nutrition or peritoneal dialysis (OR: -6.1; 95% CI: 2-18.8; P = 0.001), male sex (OR: 6.2; 95% CI: 1.9-20.3; P = 0.002) and delayed sternal closure≥2 days (OR: -3.2; 95% CI: 1-11.2; P = 0.05). CONCLUSIONS: Postoperative candidemia in children with CHD is an uncommon but severe complication. Our study revealed an unexpectedly high frequency of fluconazole-resistant C. parapsilosis as the main cause of non- albicans candidemia. In addition to confirming previously recognized risk factors, our results reveal new potential risk factors such as delayed sternal closure and male sex.

ABSTRACT

INTRODUCTION: Inactivated polio virus (IPV) vaccinations are a mainstay of immunization schedules in developed countries, while oral polio vaccine (OPV) is administered in developing countries and is the main vaccine in outbreaks. Due to circulating wild poliovirus (WPV1) detection in Israel (2013), oral bivalent polio vaccination (bOPV) was administered to IPV primed children and incorporated into the vaccination regimen. OBJECTIVES: We aimed to determine the extent and timeframe of fecal and salivary polio vaccine virus (Sabin strains) shedding following bOPV vaccination among IPV primed children. METHODS: Fecal samples were collected from a convenience sample of infants and toddlers attending 11 Israeli daycare centers. Salivary samples were collected from infants and toddlers following bOPV vaccination. RESULTS: 398 fecal samples were collected from 251 children (ages: 6-32 months), 168 received bOPV vaccination 4-55 days prior to sample collection. Fecal excretion continued among 80 %, 50 %, and 20 %, 2, 3, and 7 weeks following vaccination. There were no significant differences in the rate and duration of positive samples among children immunized with 3 or 4 IPV doses. Boys were 2.3-fold more likely to excrete the virus (p = 0.006). Salivary shedding of Sabin strains occurred in 1/47 (2 %) and 1/49 (2 %) samples 4, and 6 days following vaccination respectively. CONCLUSIONS: Fecal detection of Sabin strains among IPV-primed children continues for 7 weeks; additional doses of IPV do not augment intestinal immunity; limited salivary shedding occurs for up to a week. This data can enhance understanding of intestinal immunity achieved by different vaccination schedules and guide recommendations for contact precautions of children following bOPV vaccination.

ABSTRACT

BACKGROUND: Data regarding the compliance and safety of oseltamivir in infants < 1-year-old are limited. AIM: To compare the rates of adverse effects and compliance with oseltamivir treatment among hospitalized children aged < 1-year-old with suspected influenza and older children. METHODS: A telephone follow-up was carried out with parents of children admitted to hospital during the 2009-influenza pandemic within a week after their discharge, and their medical records were reviewed. RESULTS: A total of 89 children were included (median age was 1.3 years old); 38.2% were < 1-year-old. Only 9% were diagnosed with pH1N1 influenza. The mean duration of therapy was 3 days. Difficulty in the administration of oseltamivir was reported in 52.8% of the children. Adverse effects were reported in 53.9% of the children. The most common were vomiting and/or diarrhea (32.6%) followed by restlessness (31.8%), and rash (6.7%). Treatment of only one child was discontinued due to a possible adverse event. The rates of adverse effects and difficulties in oseltamivir administration were similar among infants < 1-yr-old and older children. CONCLUSIONS: The compliance and safety of oseltamivir therapy were similar among infants < 1-yr-old and older children. Difficulties in oseltamivir administrating and/or possible adverse effects have rarely influenced compliance. Liberal treatment with oseltamivir has led to prominent overuse of the medication.

ABSTRACT

OBJECTIVE: To evaluate the incidence of wheezing and overall respiratory morbidity in healthy infants born during the first peak of the coronavirus disease-2019 (COVID-19) pandemic, compared with infants born during the preceding year. METHODS: This was a single-center retrospective birth cohort study to compare a cohort of children born between February and March 2020 (COVID-19 group) to a control group of children born between February and March 2019 (pre-COVID-19 group). At 1 year of age, we collected respiratory data using parental and telephone questionnaires. PRIMARY OUTCOME: wheezing incidence and/or bronchodilator use. SECONDARY OUTCOMES: recurrent wheezing, emergency-room visits, hospital admissions, pneumonia diagnosis, and admissions due to lower-respiratory-tract-infections (LRTI). We included the following covariate risk factors in the logistic regression models; atopy, daycare attendance, breastmilk feeding, parental smoking, C-section, siblings, and gestational age. RESULTS: We enrolled 588 infants, 294 in each group (48% males). Demographic, perinatal, and atopic characteristics were similar between the groups. Compared to the pre-COVID-19 group, infants born during the COVID-19 period were significantly less likely to report wheezing and/or bronchodilator use (adjusted-odds ratio [OR], 0.4; 95% confidence interval [CI] 0.28-0.59), systemic steroid use, (adjusted-OR, 0.47; 95% CI 0.24-0.91), emergency-room visits (adjusted-OR, 0.36; 95% CI 0.17-0.72), LRTI admissions (adjusted-OR, 0.2; 95% CI 0.05-0.74), or pneumonia diagnosis (adjusted-OR, 0.22; 95% CI 0.09-0.53). CONCLUSIONS: This study investigated wheezing and respiratory morbidity over the first year of the COVID-19 pandemic in infants born during the first peak of COVID-19. The study demonstrated a significant decrease in most aspects of respiratory morbidity. A longitudinal follow-up study to explore the subsequent impact of these findings is warranted.

ABSTRACT

Pediatric morbidity due to unintentional poison exposure is a significant burden on public health. We prospectively characterize patterns of unintentional poison exposure in a single pediatric emergency department, using a detailed computerized questionnaire for all unintentional injuries admitted during 2009 to 2017. Out of 71,765 visits due to unintentional injuries, 252 children were admitted due to unintentional poison exposure. Most (198/252, 79%) were between 1 and 3 years of age. The majority of events (209/252, 82.9%) occurred at the patient's home and 81% (205/255) were classified as exploratory ingestion. In 41/252 (14%) cases, exposure to more than one substance was reported. Most events 231/293 (79%) involved medications and 21% were due to domestic products. Four medications account for 45% of the events (Paracetamol, Salbutamol, Antihypertensive, and Antidepressants). Opioids were responsible for only 1.7%. By, collaboration between government, public health, educational institutions and commercial companies, can the burden of pediatric unintentional poison exposure be reduced.
