The association between sinonasal anatomical variants and the laterality of orbital complications in pediatric acute rhinosinusitis.

INTRODUCTION: As the role of sinonasal anatomical variants as predisposing factors in determining the lateralization of acute rhinosinusitis-related orbital complications (ARS-OC) in pediatrics remains a topic of debate, this study further explores the potential association between anatomical variations and ARS-OC. METHODS: A retrospective study was conducted on children who had been admitted with ARS-OC using medical records and sinus CT scans to compare anatomical differences between the affected and contralateral sides. This study aimed to identify bony anatomical disparities that may impact OC laterality secondary to ARS. The anatomical features examined included septal deviation, concha bullosa, lamina papyracea dehiscence (LPD), and uncinate process abnormalities. RESULTS: The CT scans of 57 pediatric patients (114 sides) were reviewed. Our results indicated that bony anatomical variations were associated with ARS-OC laterality (63 % vs. 37 %, P = 0.006), yielding an odds ratio of 2.91. Additionally, our study revealed a significant association between ipsilateral LPD with the increased risk of ARS-OC (39 % vs. 1.8 %, P < 0.05), with an odds ratio of 34.3 compared to the opposite side. CONCLUSIONS: LPD might play a role in the pathophysiology of pediatric ARS-OC, as it is associated with a significantly higher risk of affecting the ipsilateral side. Further research is necessary to determine whether LPD is a causative factor or a result of ARS.

The effect of real-time EF automatic tool on cardiac ultrasound performance among medical students.

PURPOSE: Point-of-care ultrasound (POCUS) is a sensitive, safe, and efficient tool used in many clinical settings and is an essential part of medical education in the United States. Numerous studies present improved diagnostic performances and positive clinical outcomes among POCUS users. However, others stress the degree to which the modality is user-dependent, rendering high-quality POCUS training necessary in medical education. In this study, the authors aimed to investigate the potential of an artificial intelligence (AI) based quality indicator tool as a teaching device for cardiac POCUS performance. METHODS: The authors integrated the quality indicator tool into the pre-clinical cardiac ultrasound course for 4th-year medical students and analyzed their performances. The analysis included 60 students who were assigned to one of two groups as follows: the intervention group using the AI-based quality indicator tool and the control group. Quality indicator users utilized the tool during both the course and the final test. At the end of the course, the authors tested the standard echocardiographic views, and an experienced clinician blindly graded the recorded clips. Results were analyzed and compared between the groups. RESULTS: The results showed an advantage in quality indictor users' median overall scores (P = 0.002) with a relative risk of 2.3 (95% CI: 1.10, 4.93, P = 0.03) for obtaining correct cardiac views. In addition, quality indicator users also had a statistically significant advantage in the overall image quality in various cardiac views. CONCLUSIONS: The AI-based quality indicator improved cardiac ultrasound performances among medical students who were trained with it compared to the control group, even in cardiac views in which the indicator was inactive. Performance scores, as well as image quality, were better in the AI-based group. Such tools can potentially enhance ultrasound training, warranting the expansion of the application to more views and prompting further studies on long-term learning effects.

Does weight influence the course of RSV bronchiolitis in hospitalized infants?

Acute bronchiolitis is among the most common causes of hospitalizations in infants worldwide. Associations between weight and severity of respiratory syncytial virus (RSV) bronchiolitis remain unclear. The aim of this study was to evaluate this association. A single-center, retrospective cohort study of infants aged under 24 months, who were hospitalized between 2018 and 2022 for RSV bronchiolitis. Data from computerized medical records were extracted using the MDclone platform. Participants were divided into three groups according to weight percentiles: underweight (below 5th percentile), normal-weight, and overweight (above 85th percentile). A total of 1936 infants (mean age 6.3 months, 55% males) were included, comprising 274 infants who were underweight, 1470 with normal weight, and 192 with overweight. Underweight infants had a higher rate of admission to the pediatric intensive care unit (PICU) (9.1% vs. 3.5%, P < 0.005) and prolonged length of stay (LOS) in the hospital (3.13 vs. 2.79 days P < 0.001) compared to those with normal weight. Hyponatremia was also more common in the underweight group (23% vs. 15%, P < 0.001). A multivariable model accounting for prematurity and birthweight predicted a relative risk of 2.01 (95% CI 1.13-3.48, P = 0.015) for PICU admission and 1.42 (95% CI 1.17-1.7, P < 0.001) for a prolonged LOS. Being overweight was not associated with a more severe disease.  Conclusion: Underweight infants, hospitalized for RSV bronchiolitis, had a more severe disease course with a higher complication rate, including PICU admission and prolonged LOS. Thus, careful attention and supervision should be given to this subgroup of infants. What is Known: • Established risk factors for severe bronchiolitis include prematurity, BPD, CHD, and compromised immunity. • Abnormal weight status has been associated with an increased risk for morbidity and mortality from infectious diseases, proposedly due to the effects on endocrine and immunologic systems. What is New: • Underweight infants hospitalized with RSV bronchiolitis face an independent risk of PICU admission and prolonged hospital stay. • Conversely, overweight infants did not display associations with severity measures in our study.

Are inflammation-related diseases risk factors for primary acquired nasolacrimal duct obstruction? A large scale, national case-control study.

PURPOSE: To evaluate the incidence and risk factors for inflammatory conditions among patients with primary acquired nasolacrimal duct obstruction (PANDO). METHODS: A retrospective case-control study was conducted among patients of Clalit Health Services (CHS) in Israel from 2001 to 2022. For each case, three controls were matched among all CHS patients according to year of birth, sex, and ethnicity. Differences in demographic characteristics, ocular surface, eyelid, upper airway, and systemic diseases were assessed between the groups, and odds ratios (OR) were calculated. RESULTS: A total of 60,726 patients diagnosed with PANDO were included. The average age of PANDO patients was 63 ± 18 years, 63% were female. Significant associations were found between PANDO and various ocular surface and eyelid conditions, including chronic conjunctivitis (OR 2.96, 95% CI [2.73-3.20]), vernal keratoconjunctivitis (OR 2.89, 95% CI [2.45-3.29]), and blepharitis (OR 2.75, 95% CI [2.68-2.83]). There was a significant association with various upper airway conditions, including rhinitis (OR 1.62, 95% CI [1.58-1.66]), chronic sinusitis (OR 1.71, 95% CI [1.62-1.80]), and deviated nasal septum (OR 1.76, 95% CI [1.69-1.84]). Association was also observed with systemic conditions, including asthma (OR 1.34, 95% CI [1.27-1.41]) and atopic dermatitis (OR 1.36, 95% CI [1.32-1.41]). CONCLUSION: Ocular surface, eyelid, upper airway, and systemic inflammatory-related diseases were found to be associated with PANDO, supporting the theory that inflammation has a prominent role in the pathophysiology of PANDO.

Eradication of Nontuberculous Mycobacteria in People with Cystic Fibrosis Treated with Elexacaftor/Tezacaftor/Ivacaftor: A Multicenter Cohort Study.

BACKGROUND: The prevalence of nontuberculous mycobacteria (NTM) infections is rising in people with cystic fibrosis (pwCF). NTM infection, especially infection with Mycobacterium abscessus complex (MABC), is commonly associated with severe lung deterioration. The current treatment modalities, including multiple intravenous antibiotics, frequently fail to achieve airway eradication. Although treatment with elexacaftor/tezacaftor/ivacaftor (ETI) has been shown to modulate the lung microbiome, data regarding its role in eradicating NTM in pwCF is lacking. Our aim was to evaluate the impact of ETI on the rate of NTM eradication in pwCF. METHODS: This retrospective multicenter cohort study included pwCF from five CF centers in Israel. PwCF aged older than 6 who had at least one positive NTM airway culture in the past two years and were treated with ETI for at least one year were included. The annual NTM and bacterial isolations, pulmonary function tests, and body mass index were analyzed before and after ETI treatment. RESULTS: Fifteen pwCF were included (median age 20.9 years, 73.3% females, 80% pancreatic insufficient). In nine patients (66%) NTM isolations were eradicated following treatment with ETI. Seven of them had MABC. The median time between the first NTM isolation and treatment with ETI was 2.71 years (0.27-10.35 years). Eradication of NTM was associated with improved pulmonary function tests (p<0.05). CONCLUSIONS: For the first time, we report successful eradication of NTM, including MABC, following treatment with ETI in pwCF. Additional studies are needed to assess whether treatment with ETI can result in the long-term eradication of NTM.

Medical treatment does not reduce surgery rates in children with adenoid hypertrophy.

OBJECTIVE: We sought to study adenoidectomy rates in children with adenoid hypertrophy (AH) who were either treated with medical therapy or not during a 2-year follow-up period in a longitudinal population-based study. METHODS: We retrospectively identified healthy children aged 1-18 years between 2014 and 2020 with AH diagnosis from the Clalit Health Services database, the largest healthcare maintenance organization in Israel. The main outcome was adenoidectomy alone or in combination with other procedures performed within 2 years after diagnosis. The treatment group consisted of children who received medical therapy, defined as a pharmacy purchase of montelukast, nasal steroid sprays and/or antihistamines (medical therapy aimed to reduce AH) for ≥2 consecutive months, while the control group consisted of untreated children. RESULTS: We identified 68,356 unique children with AH, of them 56 % were boys, with a mean age of 4.9 ± 3.3 years. Of them, 5310 (7.7 %) received medical therapy. Overall, 6633 (9.7 %) underwent adenoidectomy within 2 years following diagnosis. There was no significant difference in surgery referral rates between the treatment and the control groups, 10 % vs. 9.7 %, respectively (p = 0.3). When adjusted for age and sex, the likelihood of undergoing adenoidectomy was similar in both groups (HR = 0.98, 95 % CI = 0.90-1.07, p = 0.6). Among operated children, the average time from diagnosis to surgery was statistically significantly longer in the treatment group than in the control group, 346 ± 180 vs 311 ± 175 days (p < 0.001). CONCLUSION: Prescribing montelukast, nasal steroids and/or oral antihistamines was not associated with a reduction in adenoidectomy rates and was associated with an average surgery delay of 35 days.

The Association of Therapeutic Hypothermia With Seizure Burden in Neonates With Hypoxic-Ischemic Encephalopathy.

OBJECTIVES: To compare seizure burden between newborn infants treated with therapeutic hypothermia (TH) and those that were not and to compare the need for antiseizure medications (ASM) in a cohort of infants who were diagnosed with neonatal hypoxic-ischemic encephalopathy (HIE). METHODS: This was a retrospective cohort study on infants born after 35 weeks' gestation, diagnosed with moderate to severe HIE, monitored with amplitude-integrated electroencephalography (aEEG) and eligible for TH. Infants born before the implementation of TH in 2008 were compared with infants born thereafter who received TH. Seizure burden was assessed from aEEG as total time in minutes of seizures activity per hour of recording. Other clinical and demographic data were retrieved from a prospective local database of infants with HIE. RESULTS: Overall, 149 of 207 infants were included in the study: 112 exposed to TH and 37 not exposed. Cooled infants had a lower seizure burden overall (0.4 vs 2.3 min/h, P < 0.001) and were also less likely to be treated with ASM (74% vs 100%, P < 0.001). In multivariable regression models, not exposed to TH, having a depressed aEEG background, and having higher Apgar scores were associated with higher seizure burden (incidence rate ratio: 4.78 for noncooled infants, P < 0.001); also, not exposed to TH was associated with a higher likelihood of multidrug ASM (odds ratio: 4.83, P < 0.001). CONCLUSIONS: TH in infants with moderate to severe HIE is associated with significant reduction of seizure burden and ASM therapy.

The impact of the COVID-19 pandemic on pediatric acute conjunctivitis disease trends.

The COVID-19 pandemic notably influenced the transmission of infectious diseases across various age groups. In this study, we assessed its impact on pediatric acute conjunctivitis trends in southern Israel. We analyzed acute conjunctivitis diagnoses from 2017 to 2022, categorizing them into pre-lockdown, lockdown, and post-lockdown intervals. A control group of non-infectious dermatologic conditions was included. Time-series analysis, adjusted for seasonality, was employed. Pre-lockdown data indicated steady conjunctivitis diagnoses, primarily in winter. Post-lockdown interval exhibited an added summer peak before the regular winter surge. The lockdown saw a 56% decline in diagnoses, most pronounced in younger ages. Post-lockdown observed a 7% overall drop with age-specific variations. The acute conjunctivitis IRR was 0.44 (95% CI 0.39-0.49) during lockdowns and 0.93 (95% CI 0.86-1.02) post-lockdowns. Control group IRRs were 0.84 (95% CI 0.78-0.89) and 0.90 (95% CI 0.84-0.96), respectively, with the 0-5 age range demonstrating significant disparities. Pediatric acute conjunctivitis in southern Israel decreased significantly during the pandemic. Post-lockdown patterns varied by age group. An unusual summer peak in cases was observed post-lockdown; this peak may be influenced by a combination of altered behaviors in the summer and possibly increased susceptibility to infection.

Monocyte and neutrophil to lymphocyte ratios in hospitalized children with RSV bronchiolitis.

OBJECTIVE: Acute bronchiolitis is the most common cause of hospitalization in young children. Data on monocyte-to-lymphocyte-ratio (MLR) and neutrophil-to-lymphocyte-ratio (NLR) as biomarkers are limited. We aim to evaluate these ratios in children hospitalized with respiratory syncytial virus (RSV) bronchiolitis and their value as biomarkers for severe clinical outcomes. STUDY DESIGN: A single-center retrospective cohort study of children aged <2 years hospitalized due to RSV bronchiolitis, between January 2018 and March 2022, with a complete blood count upon admission. We divided the cohort into quartiles based on MLR and NLR values. We examined associations between quartiles and four clinical severity outcomes. RESULTS: A total of 2038 children (median age: 4.4 months, IQR: 1.9-9.8) were included in the study. The median MLR and NLR values for quartiles 1-4 were 0.14, 0.22, 0.30, 0.47, and 0.37, 0.70, 1.16, 2.29, respectively. Children with higher MLR had higher hospitalization rates to the pediatric intensive care unit (PICU) (Q1 2.4%, Q4 9.4%, p < .001), extended hospital stays (Q1 19.4%, Q4 32%, p < .001), and lower minimal oxygen saturation (Q1 90%, Q4 87%, p < .001). Cut-off values of 0.34 for MLR and 0.67 for NLR optimally identified PICU admissions. In a model accounting for age and sex, the fourth MLR quartile had an RR of 3.4 (95% CI: 1.76-7.22) and successfully predicted PICU admissions (area under the curve = 0.73; 95% CI: 0.681-0.789). CONCLUSIONS: MLR and NLR are potential biomarkers for identifying children with RSV bronchiolitis at a higher risk for severe outcomes, specifically PICU admission.

Rates of Delayed Postcochlear Implant Pain in the Pediatric Population-Role of Proactive Approach.

OBJECTIVE: To investigate the rates of delayed postoperative cochlear implantation pain (DPCIP) in the pediatric population, using a "reach-out" proactive approach. Secondary aims included the possible impact of surgery extent or the patient ethnicity on DPCIP rates. MATERIALS AND METHODS: A cross-sectional study was conducted at Soroka University Medical Center in Israel. Demographics and data regarding the surgery and surgical complications were collected from the medical records of the patients. A telephone questionnaire was conducted for parents of all children who underwent cochlear implantation (CI) between 2007 and 2020. The questions addressed pain at four time periods: during hospitalization after surgery, 3 months, 2 years, and 5 years after surgery. RESULTS: Out of 213 patients, 129 (60%) were included in this study. The mean age was 41 months (±40). Unilateral CI was performed in 72 (56%) patients. At 3 months and 2 years after surgery, 8.5% of patients reported pain (visual analog scale [VAS] ≥ 1). Five years after surgery, a slight increase in the number of patients who reported pain (12%) was observed. Of those experiencing pain 2 years and 5 years after surgery, 10/12 (83%) and 11/16 (69%), respectively, reported a new onset of the pain. Surgery extent and cultural background were not significantly associated with DPCIP rates. No correlations were found between patients complaining of pain and any surgical complications. CONCLUSIONS: DPCIP rates may be underrecognized and higher than previously reported, reaching up to 12%. This long-term effect should be acknowledged and discussed with parents upon informed consent.

Are Periocular and Systemic Allergy Conditions Risk Factors for Pterygium?

PURPOSE: To evaluate risk factors for pterygium and prevalence of periocular and systemic diseases among patients with pterygium. METHODS: A retrospective case-control study was conducted among members of Clalit Health Services (CHS) in Israel, from 2001 to 2022. A total of 13,944 patients diagnosed with pterygium were included. For each case, three controls were matched among all CHS patients according to year of birth, sex, and ethnicity. Mixed models were used to assess differences in demographic characteristics, ocular and systemic diseases between the groups. Generalized estimating equation (GEE) logistic regression was used to estimate the odds ratios (OR) and adjust for confounders. RESULTS: The average age of pterygium patients was 49 ± 17 years; 51% were male. The results showed significant associations between pterygium and risk factors of vernal kerato-conjunctivitis (OR 2.52, 95% confidence interval [CI]: [1.96-3.24]), chronic allergic conjunctivitis (OR 1.98, 95% CI: [1.65-2.39]), blepharitis (OR 1.91, 95% CI: [1.78-2.04]), chalazion (OR 1.47, 95% CI: [1.30-1.67]) and unspecified systemic allergy (OR 1.21, 95% CI [1.09-1.34]), after adjusting for rural residency status. Glaucoma (OR 0.74, 95% CI [0.64-0.85]) and smoking (OR 0.70, 95% CI [0.66-0.75]) were protective factors against pterygium. CONCLUSION: Systemic and periocular inflammatory and allergic diseases are risk factors for pterygium.

Clinical characteristics of SARS-CoV-2 vaccine-related acute appendicitis.

BACKGROUND: In a large nationwide mass vaccination setting, the SARS-CoV-2 vaccine was recently linked to myocarditis, lymphadenopathy, herpes zoster infection and appendicitis. We aimed to examine the characteristics and management of SARS-CoV-2 vaccine-related acute appendicitis. METHODS: We performed a retrospective cohort study in a large tertiary medical centre in Israel. All patients presenting with acute appendicitis within 21 days of receiving their SARS-CoV-2 vaccination (PCVAA group) were compared with patients who presented with acute appendicitis not related to the vaccination (N-PCVAA group). RESULTS: We reviewed the records of 421 patients with acute appendicitis from December 2020 to September 2021; 38 (9%) patients presented with acute appendicitis within 21 days of receiving their SARS-CoV-2 vaccination. Patients in the PCVAA group were older than those in the N-PCVAA group (mean 41 ± 19 yr v. 33 ± 15 yr, respectively, p = 0.008), with male predominance. More patients were managed nonsurgically during the pandemic than before the pandemic (24% v. 18%, p = 0.03). CONCLUSION: With the exception of older age, the clinical characteristics of patients presenting with acute appendicitis within 21 days of receiving the SARS-CoV-2 vaccination did not differ from those of patients who presented with acute appendicitis not related to the vaccination. This finding suggests that vaccine-related acute appendicitis is similar to "classic" acute appendicitis.

Elevated Neutrophil-to-Lymphocyte Ratio Is Associated with Severe Asthma Exacerbation in Children.

Asthma is the most common chronic respiratory disease in children. The neutrophil-to-lymphocyte ratio (NLR) is a marker of a chronic inflammatory state; however, data on the association of NLR with acute asthma exacerbations in children is lacking. In this cross-sectional study, between 2016 and 2021, children aged 2-18 years who were referred to the emergency department (ED) due to asthma exacerbation, were included. NLR, calculated from complete blood count upon arrival, was assessed as a continuous variable and was classified into four groups according to quartiles. The association between severity parameters and NLR quartiles was examined. A total of 831 ED visits for asthma exacerbation were included in the study. The median NLR was 1.6, 3.8, 6.7, and 12.9 in quartiles 1-4, respectively (p < 0.001). Demographic parameters, background diseases, and chronic medications were similar between the quartiles. Higher heart rate, body temperature, systolic blood pressure, and respiratory rate were observed in the higher NLR quartiles, as well as lower oxygen saturation. Higher urgency scale and higher rates of intravenous magnesium sulfate were observed in the higher NLR quartiles, with higher admission rates and prolonged hospitalizations. In summary, NLR upon admission is associated with the severity of asthma exacerbation and higher chances of hospitalization among children in the ED.

Acute otitis media in the first two months of life and the impact of pneumococcal conjugate vaccines: A retrospective cohort study.

BACKGROUND: Information on pneumococcal vaccination's impact on the prevention of acute otitis media (AOM) at very young ages is limited. OBJECTIVES: To define the trends in tympanocentesis-proven AOM incidence, clinical characteristics, microbiology, and antibiotic resistance in infants <2 months of age in southern Israel, before and after the sequential introduction of 7- and 13-valent PCVs. METHODS: A retrospective population-based cohort study including children <2 months of age diagnosed with AOM at the pediatric emergency room between January 2005-Decmber 2009 (pre-vaccination group, group 1) and January 2013-July 2021 (post-PCV13 introduction, group 2). RESULTS: 160 patients were enrolled, 89 (55.6%) in group 1 and 71 (44.4%) in group 2. The mean incidence of AOM decreased from 1.2 cases/1000 live births for group 1 to 0.45 cases/1000 live births for group 2, P < 0.001.130 (81.25%) patients were hospitalized, with higher hospitalization rates in group 1 vs. group 2 (84/89, 94% vs. 46/71, 65%, P < 0.001). Hospitalization length was longer in group 1 vs. group 2 (4.07 ± 4.09 days vs. 2.70 ± 1.82 days, P = 0.021). Positive MEF cultures were reported in 94/160 (58.75%) patients, with a decrease in positivity rates between the 2 groups (71/89, 80% vs. 23/71, 32%, P < 0.001). S. pneumoniae was the most common pathogen (55/94, 58.5%); it was the most frequent pathogen isolated in group 1 (46/71, 65%), and the second most common pathogen in group 2 (9/23, 39%), P = 0.03. A significant increase was recorded in the percentages of patients with negative MEF cultures (from 21% to 68%, P < 0.001). CONCLUSIONS: The introduction and implementation of PCV13 in southern Israel was associated with a decrease in AOM in children <2 months of age and of S. pneumoniae recovery in these patients and was accompanied by less admissions and shorter hospitalizations. An increase in the proportions of negative bacterial cultures from MEF was recorded during the study period.

Has COVID-19 Changed Pediatric Acute Rhinosinusitis Epidemiology During the First 2 Pandemic Years?

OBJECTIVE: To study national pediatric acute rhinosinusitis (ARS) burden fluctuations before and during the first 2 coronavirus-19 (COVID) years, characterized by alternating lockdown and relaxation periods, the introduction of COVID vaccines, and the emergence of nonalpha COVID variants. METHODS: This was a cross-sectional, population-based study covering the 3 pre-COVID years and the first 2 COVID years from a big database of the largest Israeli Health Maintenance Organization. For comparison purposes, we explored ARS burden trends with those of urinary tract infection (UTI), which is unrelated to viral diseases. We identified children <15 years presenting with ARS and UTI episodes and categorized them according to their age and presentation date. The average ARS and UTI episodes of the 3 pre-COVID years were used to calculate the incidence rate ratios (IRRs) of the 2 COVID years, analyzed separately. Seasonal variations were explored. RESULTS: We identified 44,483 ARS and 121,263 UTI episodes. There was a substantial reduction in ARS episodes during the COVID years (IRR 0.36, 95% CI: 0.24-0.56, P < 0.001). Although UTI episode rates also decreased during COVID (IRR 0.79, 95% CI: 0.72-0.86, P < 0.001), the reduction in ARS burden was 3-fold higher. The dominant pediatric ARS age group was between 5 and 15 years. The largest decrease in ARS burden was during the first COVID year. ARS episode distribution showed a seasonal fluctuation, with a peak during the summer months during the COVID years. CONCLUSIONS: Pediatric ARS burden decreased during the first 2 COVID years. Episode distribution was noted to be year-round.

Glycemic control and macular edema in patients undergoing cataract surgery.

AIMS: Cataract, the most common cause of blindness, has higher prevalence among patients with diabetes mellitus. About 20% of cataract surgeries are performed on patients with diabetes. One of the complications of cataract surgery is pseudophakic cystoid macular edema (CME). This study examined whether patients' glycemic control (as indicated by HbA1c level before cataract surgery) is associated with CME incidence within one year post-surgery. METHODS: We conducted a retrospective cohort study of 1285 diabetes patients over age 18 who underwent cataract surgery between January 2015 and January 2020. Data were obtained from medical records reporting glycated hemoglobin (HbA1c) level prior to surgery and post-operative CME with intraocular anti-vascular endothelial growth factor injections. RESULTS: The patients with CME complications were younger, with longer duration diabetes, and higher percentages of type 1 diabetes and diabetic retinopathy. The main variables influencing risk of post-operative CME were found to be diabetic retinopathy and HbA1c level. Multivariate analysis revealed that HbA1c is an independent risk for post-operative CME with a relative risk of 2.01 when HBa1c is above 7 c (95% CI, 1.10-3.67). CONCLUSION: The study demonstrates that pre-cataract surgery diabetes control, measured by HbA1c level, is an independent risk factor for developing post-surgery CME.

Fluctuations in Pediatric Acute Otitis Media Burden During the First Two COVID-19 Years in Israel.

BACKGROUND: To study pediatric acute otitis media (AOM) burden fluctuations before and during the first two COVID years, which were characterized by measures to reduce the spread of airborne diseases. We used urinary tract infection (UTI) as a comparison infection. METHODS: This was a cross-sectional study encompassing three pre-COVID years (March 1, 2017-February 29, 2020) and the first two COVID years (March 1, 2020-February 28, 2021, and March 1, 2021-February 28, 2022). Records were retrieved from the Clalit Health Services database, Israel's largest healthcare maintenance organization. Children 0-15 years with AOM and UTI episodes were categorized according to age (1>, 1-4, 5-15 years). We collected demographics, seasonality, AOM complications, antibiotic prescriptions, and recent COVID-19 infections. The average AOM/UTI rates of the three pre-COVID years vs. two COVID years were used to calculate the incidence rate ratios (IRRs). RESULTS: We identified 1,102,826 AOM and 121,263 UTI episodes. The median age at AOM diagnosis was 2.0 years (IQR, 1.1-4.1). Male predominance, age at presentation, and the dominant age group of 1-4 years did not change during the COVID years. While UTI episode rates decreased during the COVID years (IRR 0.76, 95% CI, 0.68-0.84, P < 0.001), the reduction in AOM episode rates was >2-fold (IRR 0.46, 95% CI, 0.34-0.63, P < 0.001). The largest decrease was observed among children 1-4 years old during the first COVID year (ß=-1,938 AOM episodes/100,00 children, 95% CI, -2,038 to -1,912, P < 0.001). Recent COVID-19 infection was associated with low AOM morbidity (IRR 0.05, 95% CI 0.05-0.05, P < 0.001). CONCLUSIONS: AOM burden substantially decreased during the first COVID year but almost reached pre-pandemic levels during the second year.

Characterization of pregnancy outcome of women with an offspring with inborn errors of metabolism: A population-based study.

Introduction: Inborn errors of metabolism (IEM) are scarce, and their diagnosis is often made after birth. This has led to the perception that most fetuses affected by these disorders do not become clinically apparent during pregnancy. Our aim was to determine the obstetrical characteristics of women with an offspring affected by IEM. Methods: This population-based retrospective cohort study included all women who delivered at the Soroka University Medical Center (SUMC) from 1988 to 2017 who met the inclusion criteria. Mothers who had an offspring with IEM were included in the study group, and those who had offsprings without IEM comprised the comparison group. Results: A total of 388,813 pregnancies were included in the study, and 184 of them were complicated by a fetus with IEM. The number of Bedouin women was higher in the IEM-affected infant group than in the comparison group (90.8% vs. 53.3%, p < 0.001); women who had a fetus with IEM had a higher rate of polyhydramnios (7.1% vs. 3.2%, p = 0.005), HELLP syndrome (3.3% vs. 1.1%, p = 0.014), and preterm birth (20.7% vs. 10.1%, p < 0.001); neonates with IEM had lower mean birth weight (p < 0.001), lower Apgar scores at 1' and 5' minutes (p < 0.001), and a higher rate of fetal growth restriction (FGR) (p < 0.001), postpartum death <28 days (p < 0.001), and neonatal death (p < 0.001) than those in the comparison group. Pregnancies with IEM fetuses were independently associated with preterm birth (OR 2.00; CI 1.4-3), polyhydramnios (OR 2.08; CI 1.17-3.71), and FGR (OR 2.24; CI 1.2-4.19). Each family of metabolic diseases is independently associated with specific pregnancy complications (i.e., mitochondrial diseases are associated with HELLP syndrome (OR 5.6; CI 1.8-17), and lysosomal storage disease are associated with nonimmune hydrops fetalis (OR 26.4; CI 3.39-206). Conclusion: This study reports for the first time, an independent association of IEM with specific complications of pregnancy. This observation has clinical implications, as the identification of specific pregnancy complications in a population at risk for IEM can assist in the prenatal diagnosis of an affected fetus.

The Association between Gestational Age and Risk for Long Term Ophthalmic Morbidities among Offspring Delivered in Different Preterm Subgroups.

Objective: To investigate whether there is a linear association between the degree of prematurity and the risk for long-term ophthalmic morbidity among preterm infants. Study design: A population-based, retrospective cohort study, which included all singleton deliveries occurring between 1991 and 2014 at a single tertiary medical center. All infants were divided into four groups according to gestational age categories: extremely preterm births, very preterm births, moderate to late preterm births and term deliveries (reference group). Hospitalizations of offspring up to 18 years of age involving ophthalmic morbidity were evaluated. Survival curves compared cumulative hospitalizations and regression models controlled for confounding variables. Results: During the study period, 243,363 deliveries met the inclusion criteria. Ophthalmic-related hospitalization rates were lower among children born at term (0.9%) as compared with extremely preterm (3.6%), very preterm (2%), and moderate to late preterm (1.4%) born offspring (p < 0.01; using the chi-square test for trends). The survival curve demonstrated significantly different hospitalization rates between the gestational ages (p < 0.001). The regression demonstrated an independent risk for ophthalmic morbidity among extremely preterm born offspring (adjusted hazard ratio 3.8, confidence interval 1.6−9.2, p < 0.01), as well as very preterm and moderate to late preterm (adjusted hazard ratio 2.2 and 1.5, respectively) as compared with term deliveries. Conclusions: The risk for long-term ophthalmic-related hospitalization of preterm offspring gradually decreases as the gestational age increases.
