Antibiotics for Clinical Dysentery in the Pediatric Emergency Department.

BACKGROUND: Clinical dysentery causes hundreds of thousands of deaths annually worldwide. However, current recommendations reserve antibiotics for those either clinically sick or with highly suspected cases of shigellosis. This treatment stems from rising antibiotic resistance. Children diagnosed with clinical dysentery in the pediatric emergency department (PED) are regarded more cautiously. OBJECTIVES: To explore the use of antibiotics in children diagnosed with clinical dysentery in the PED. METHODS: A retrospective case study of children with clinical dysentery at a single PED during the years 2015 and 2018. Demographics as well as clinical findings were compared to culture results and antibiotic treatment. RESULTS: The study included 281 children who were diagnosed with clinical dysentery during the study period; 234 (83%) were treated with antibiotics. However, cultures were positive in only 162 cases (58%). Only 32% were Shigella spp. Younger age, fever, and leukocytosis were related to antibiotic treatment. CONCLUSIONS: The diagnosis of clinical dysentery is misgiven commonly in the PED leading to widespread use of antibiotics when not indicated. This treatment may impact antibiotic resistance patterns. Further studies and interventions are necessary to create clear guidelines in the PED setting.

Management of intraorbital infections in the pediatric emergency department.

Intraorbital infections may lead to severe complications, necessitating rapid diagnosis and intervention. The decision process regarding the need for emergent imaging and possible surgical intervention is unclear in the literature. This retrospective cohort study included two major pediatric emergency departments in Israel between 2010 and 2020. Patients arriving at the emergency department with an admission diagnosis of intraorbital infection and at least one high-risk symptom for orbital involvement were included in the study. The main outcome measures were the computerized tomography (CT) timing and results, whether the case was managed surgically or conservatively and whether the patient returned to the same hospital with significant complications. Ninety-five patients were included; 70 underwent a CT scan in the first 24 h, and of those 21 were managed surgically; 16 were treated based on clinical findings alone, with no imaging performed. When comparing groups based on management, we found no significant differences based on presenting symptoms, duration of complaints, or severity of CT findings. However, having three or more high-risk presenting symptoms was associated with a greater likelihood of surgical intervention (multivariate logistic regression p = 0.069, odds ratio 1.73, 95% confidence interval 0.96-3.11; one-way ANOVA and Fisher's exact test p < 0.05). CONCLUSION: The decision to treat intraorbital infections at our institutions appears to be based on clinical impression of disease severity rather than radiologic findings. This suggests a need for further interdisciplinary studies to clarify optimal management. WHAT IS KNOWN: • Orbital c ellulitis is associated with significant potential complications, necessitating rapid diagnosis and treatment. • Present literature provides insufficiently clear guidance on emergency department management. WHAT IS NEW: • Consideration of all relevant factors (clinical features, laboratory findings, timing of imaging, and conservative vs. surgical management) in a single retrospective cohort. • Our findings suggest that decision-making in practice may be guided by clinical impression rather than imaging.

Successful Outcome in an Adolescent with Artery of Percheron Occlusion who was Treated with Tissue Plasminogen Activator.

BACKGROUND: Ischemic stroke is relatively rare in children, leading to a low level of suspicion and delayed diagnosis, particularly in cases of posterior circulation occlusion when symptoms are less indicative. Occlusion of the artery of Percheron (AOP) results in nonspecific neurologic symptoms, including drowsiness, aphasia or dysarthria, ophthalmoplegia, ataxia, and dysmetria. Previous reports, mainly in adults, described late diagnosis and severe residual disability. CASE REPORT: We report a case of a 16-year-old male who presented to the pediatric emergency department with altered mental status. There was no history of trauma or intoxication. The main symptoms included confusion, slurred speech, and multiple falls starting 1 h before arrival to the emergency department. No motor deficits or other focal signs were noticed. The patient's consciousness gradually decreased followed by apneic events. Routine laboratory tests, urinary toxic screen, and a computed tomography scan of the head were normal. A magnetic resonance imaging scan of the brain revealed bilateral restrictive changes in the thalamus. A diagnosis of AOP occlusion was made, and the patient was treated with tissue plasminogen activator (6 h after symptom onset). He was extubated on day 4 and discharged on the day 10 of admission without any neuropsychological deficit. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Posterior circulation stroke in the pediatric population is a diagnostic challenge that often results in suboptimal treatment and unfavorable outcomes. Prompt imaging studies in children with nonspecific altered mental status enable timely diagnosis and thrombolytic treatment that may substantially improve the outcome.

The utility of MALDI-TOF MS for outbreak investigation in the neonatal intensive care unit.

Our aim was to evaluate the performance of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), routinely used in the microbiology laboratory for bacterial identification, for bacterial typing in the setting of extended spectrum beta-lactamase producing Klebsiella pneumoniae (ESBL-KP) outbreak in the neonatal intensive care unit (NICU). Isolates from a 2011 outbreak in the NICU were retrieved from frozen stocks and analyzed by MALDI-TOF. The MALDI typing was compared with core genome multilocus sequence typing (cg-MLST). MALDI typing divided the 33 outbreak isolates into 2 clones: sequence type (ST)-290 and 405. These results were in complete agreement with cg-MLST results. The differentiation of the outbreak isolates into two clones correlated with the patients' location in the NICU, but also with their place of residence.Conclusion: Here, we show that MALDI-TOF MS, which has been integrated into the microbiology laboratory workflow for microbial species identification, can be secondarily used for epidemiological typing at no added cost. What is Known: • Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is now routinely used in the microbiology laboratory for bacterial identification What is New: • MALDI typing was used for outbreak investigation in the NICU and divided the outbreak isolates into two clones • MALDI-TOF MS may be secondarily used for epidemiological typing at no added cost.

Stress Hyperglycemia in a Pediatric Emergency Department Setting and its Relationship to the Underlying Disease and Outcome.

BACKGROUND: Stress hyperglycemia (SH) is a common finding in patients in pediatric emergency departments (PED) and has been related to increased morbidity and mortality. OBJECTIVES: To assess the incidence of SH among children visiting the PED. To identify which diseases predispose patients to SH and whether they indicate a worse outcome. METHODS: Data were collected retrospectively from the medical records of all children aged 0-18 years who visited the PED during the years 2010-2014 and who had a glucose level of ≥ 150 mg/dl. Data collected included age, gender, weight, blood glucose level, presence or absence of a pre-existing or a new diagnosis of diabetes mellitus, and previous treatment with medications affecting blood glucose levels or with intravenous fluids containing dextrose. Data were collected regarding hospitalization, duration of hospitalization, discharge diagnosis, and survival status. RESULTS: The study population included 1245 children with SH, which comprised 2.6% of all patients whose blood glucose level was measured in the PED during the study period. The mean age of children with SH was 49 months; 709 (56.9%) were male. The mean blood glucose level was 184 mg/dl. The rate of hospitalization was 57.8%. The mean duration of hospital stay was 5.6 days and mortality rate was 0.96%. The majority were diagnosed with a respiratory illness. CONCLUSIONS: SH is a common phenomenon among children evaluated in the PED and is associated with a high incidence of hospitalization. It may serve as an additional clinical indicator of disease severity.

Jerusalem's CoVID-19 Experience-The Effect of Ethnicity on Disease Prevalence and Adherence to Testing.

BACKGROUND: The management of the SARS-CoV-2 pandemic depends amongst other factors on disease prevalence in the general population. The gap between the true rate of infection and the detected rate of infection may vary, especially between sub-groups of the population. Identifying subpopulations with high rates of undetected infection can guide authorities to direct resource distribution in order to improve health equity. METHODS: A cross-sectional epidemiological survey was conducted between April and July 2021 in the Pediatric Emergency Department of the Shaare Zedek Medical Center, Jerusalem, Israel. We compared three categories: unconfirmed disease (UD), positive serology test result with no history of positive PCR; confirmed disease (CD), history of a positive PCR test result, regardless of serology test result; and no disease (ND), negative serology and no history of PCR. These categories were applied to local prevailing subpopulations: ultra-orthodox Jews (UO), National Religious Jews (NRJ), secular Jews (SJ), and Muslim Arabs (MA). RESULTS: Comparing the different subpopulations groups, MAs and UOs had the greatest rate of confirmed or unconfirmed disease. MA had the highest rate of UD and UO had the highest rate of CD. UD significantly correlated with ethnicity, with a low prevalence in NRJ and SJ. UD was also associated with larger family size and housing density defined as family size per number of rooms. CONCLUSION: This study highlights the effect of ethnicity on disease burden. These findings should serve to heighten awareness to disease burden in weaker populations and direct a suitable prevention program to each subpopulation's needs. Early awareness and possible intervention may lower morbidity and mortality.

[Congenital skull base defect causing recurrent bacterial meningitis].

Bacterial meningitis is a life threatening disease. Most patients will experience only one episode throughout life. Children who experience bacterial meningitis more than once, require further immunologic or anatomic evaluation. We report a 9 year old child with five episodes of bacterial meningitis due to a congenital defect of the skull base. A two and a half year old boy first presented to our medical center with pneumococcal meningitis. He was treated with antibiotics and fully recovered. Two months later he presented again with a similar clinical picture. Streptococcus pneumoniae grew in cerebrospinal fluid (CSF) culture. CT scan and later MRI of the brain revealed a defect in the anterior middle fossa floor, with protrusion of brain tissue into the sphenoidal sinus. Corrective surgery was recommended but the parents refused. Three months later, a third episode of pneumococcal meningitis occurred. The child again recovered with antibiotics and this time corrective surgery was performed. Five years later, the boy presented once again with clinical signs and symptoms consistent with bacterial meningitis. CSF culture was positive, but the final identification of the bacteria was conducted by broad spectrum 16S ribosomal RNA PCR (16S rRNA PCR) which revealed a sequence of Neisseria lactamica. CT and MRI showed recurrence of the skull base defect with encephalocele in the sphenoid sinus. The parents again refused neurosurgical intervention. A year later the patient presented with bacterial meningitis. CSF culture obtained after initiation of antibiotics was negative, but actinobacillus was identified in the CSF by 16S rRNA PCR. The patient is scheduled for neurosurgical intervention. In patients with recurrent bacterial meningitis caused by organisms colonizing the oropharynx or nasopharynx, an anatomical defect should be carefully sought and surgically repaired.

"Feed and Swaddle" method of Infants Undergoing Head CT for minor head injury in the pediatric emergency department - A comparative case review.

INTRODUCTION: Brain imaging for suspected significant head injuries in pediatric emergency departments is an important and time-sensitive procedure. The use of sedation to successfully complete imaging can be limited due to young age and other injury related factors. Using a non-pharmacological method using feeding and swaddling can be used. This may obviate the need for sedation but can be time consuming. METHODS: A retrospective study of all children undergoing brain imaging for head injury during the years 2016-2021. Use of sedation, time to completion and imaging findings were compared. RESULTS: Of 281 children requiring brain imaging, 268 (95.4%) were completed using the feed and swaddle method. Time to imaging completion was similar between sedation and feed and swaddle groups (85.5 min vs. 86 min). Abnormal findings on imaging were found in 186 (69.4%) in the feed and swaddle group and in 10 (77%) of the sedation group. No adverse events were seen in the sedation group. CONCLUSION: Using the feed and swaddle method can help lower the need for sedation in the under 1 year age group with a successful and timely completion of brain imaging.

The rates of hospital admissions and return visits to a rapidly growing pediatric emergency department as measures of quality of care.

BACKGROUND: Return visits to the emergency department are viewed as a quality measure of patient management. Avoiding unnecessary admissions to the ward can potentially cause an increase in return visits, thus effecting quality assessment. METHODS: After implementing an educational process the relationship between admissions and return visits was assessed over time at a rapidly growing pediatric emergency department. RESULTS: There was a 264% increase in visits from 2004 to 2017. In the study period admission rates declined from 25 to 14%. This was achieved without a rise in return visits and with a stable percentage of admissions from return visits. CONCLUSIONS: Interventions aimed at decreasing unnecessary admissions do not lead to increased return visits and return visit admissions.
