Facial vs Non-facial Molluscum Contagiosum Infection in Children: A Cross-sectional Study.

Molluscum contagiosum is a common skin infection affecting different body areas, including the face. Previous data have shown cases of atypical lesions, notably on the face, and it was thought relevant to further examine differences between facial and non-facial lesions. All cases of children (0-18) diagnosed with molluscum contagiosum from 2013-2022 at the paediatric dermatology clinic of Soroka University Medical Center were retrospectively reviewed, and 615 children were included in the study. Facial lesions tended to be found in younger children (p = 0.018). Non-facial lesions were more erythematous (p < 0.001), itchier (p < 0.001), and showed similar patterns of ulceration (p = 0.078) and purulence (p = 0.779). The average lesion diameter was similar in patients with or without facial lesions (p = 1). Children with facial lesions were treated differently from patients without facial lesions (p < 0.001); however, there were no differences in treatment response. This research challenges assumptions concerning the severity of facial lesions, including eyelid lesions, by revealing that, overall, they exhibit less inflammation than non-facial lesions. Despite the potential for greater psychosocial burdens and impacts on self-esteem associated with lesions on the sensitive facial area, this study provides evidence that they are not inherently more worrisome and can be managed similarly to lesions found elsewhere in the body.

Assessing the impact of medically assisted reproduction on autism spectrum disorder risk.

Techniques of medically assisted reproduction interact with the embryo at crucial developmental stages, yet their impact on the fetus and subsequent child's health remains unclear. Given rising infertility rates and more frequent use of fertility treatments, we aimed to investigate if these methods heighten the risk of autism spectrum disorder (ASD) in children. A population-based cohort study was conducted at Soroka University Medical Center, a tertiary referral hospital, encompassing singleton births. The incidence of ASD in offspring, incorporating either hospital or community-based diagnoses, was compared in relation to the conception method. To examine the cumulative incidence of ASD, a Kaplan-Meier survival curve was utilized. Cox proportional hazards model was employed to adjust for confounders. Among 115,081 pregnancies, 0.5% involved ovulation induction (OI) and 1.7% in vitro fertilization (IVF), with the rest conceived naturally. Fertility treatments were more common in older patients and linked to more diabetes, hypertensive disorders, preterm, and cesarean deliveries. Out of 767 ASD diagnoses, offspring from OI and IVF had higher initial ASD rates (2.1% and 1.3%) than natural conceptions (0.6%). In a Cox model accounting for maternal age, ethnicity, and gender, neither OI nor IVF was significantly associated with ASD. The adjusted hazard ratios were 0.83 (95% CI 0.48-1.43) for OI and 1.34 (95% CI 0.91-1.99) for IVF. When considering fertility treatments combined, the association with ASD remained non-significant (aHR 1.11, 95% CI 0.80-1.54, p = 0.52). Fertility treatments, including OI and IVF, do not exhibit a significant association with heightened ASD risk in offspring.

Neonatal diagnosis of primary ciliary dyskinesia in a high consanguinity population: a single tertiary center experience.

Though PCD usually presents after birth in term neonates, diagnosing PCD during the neonatal and infancy stages is uncommon, particularly in children who do not exhibit laterality defects. We report our recent experience with the diagnosis of PCD in the neonatal and early infantile period in a highly consanguine population. This was achieved by implementing a novel genetic-based diagnostic approach based on direct testing for recognized regional genetic variants. We conducted a retrospective analysis of children diagnosed with PCD at Soroka University Medical Center during the neonatal or early infantile period between 2020 and 2023. We included children under 3 months of age who had a genetic confirmation of PCD, as evidenced by the presence of two pathogenic variants in recognized genes. Genetic testing targeted regional genetic variants in previously identified PCD genes. Eight patients were included. The median age at diagnosis was 12.5 days. Three (38%) were born prematurely < 34 weeks gestational age. All patients were presented with respiratory distress and hypoxemia after birth. The median duration of oxygen support was 23 days, and upper lobe atelectasis was present in five patients (63%). Congenital cardiac malformation was present in four patients. Organ laterality defects were present in four patients. Genetic mutations identified were in the DNAAF5, DNAL1, DNAAF3, and DNAH1 genes. Conclusion: Neonatal diagnosis of PCD is uncommon, especially in atypical presentations such as children without laterality defects or preterms. Focusing on a genetic diagnosis of the local tribal pathogenic variants promotes a potential cost-efficient test leading to earlier diagnosis. There is a need for a standardized protocol for earlier diagnosis of PCD in high-consanguinity areas. What is Known: • Primary ciliary dyskinesia (PCD) typically presents after birth in term neonates. • Diagnosing PCD during neonatal and infancy stages is challenging, particularly in children without laterality defects. What is New: • A novel genetic-based diagnostic approach was implemented on the neonatal population in a highly consanguine community, focusing on direct testing for regional genetic variants, leading to early and rapid diagnosis of PCD.

Orchiopexy: one procedure, two diagnoses - different male infertility outcomes.

Infertility, affecting one in six couples, is often related to the male partner's congenital and/or environmental conditions or complications postsurgery. This retrospective study examines the link between orchiopexy for undescended testicles (UDT) and testicular torsion (TT) in childhood and adult fertility as assessed through sperm analysis. The study involved the analysis of semen samples from 7743 patients collected at Soroka University Medical Center (Beer Sheva, Israel) between January 2009 and December 2017. Patients were classified into two groups based on sperm concentration: those with concentrations below 5 × 106 sperm per ml (AS group) and those above (MN group). Medical records and surgical histories were reviewed, categorizing orchiopexies by surgical approach. Among 140 individuals who had undergone pediatric surgery, 83 (59.3%) were placed in the MN group and 57 (40.7%) in the AS group. A higher likelihood of being in the MN group was observed in Jewish compared to Arab patients (75.9% vs 24.1%, P = 0.006). In cases of childhood UDT, 45 (78.9%) patients exhibited sperm concentrations below 5 × 106 sperm per ml (P < 0.001), and 66 (76.7%) had undergone unilateral and 18 (20.9%) bilateral orchiopexy. Bilateral orchiopexy was significantly associated with lower sperm concentration, total motility, and progressive motility than unilateral cases (P = 0.014, P = 0.001, and P = 0.031, respectively). Multivariate analysis identified UDT as a weak risk factor for low sperm concentration (odds ratio [OR]: 2.712, P = 0.078), with bilateral UDT further increasing this risk (OR: 6.314, P = 0.012). Jewish ethnicity and TT diagnosis were associated with a reduced risk of sperm concentrations below 5 × 106 sperm per ml. The findings indicate that initial diagnosis, surgical approach, and ethnicity markedly influence male fertility outcomes following pediatric orchiopexy.

Prenatal exposure to acid suppressor medications and development of ductus arteriosus in term newborn.

The ductus arteriosus normally closes after birth. Histamine2 Receptor Antagonist (H2RA) has been associated with patent ductus arteriosus (PDA). We aimed to study the characteristics of term infants with PDA and their possible association with prenatal exposure to antacids - Proton Pump Inhibitors (PPI) and H2RA. Population-based matched case-control study of mothers registered at "Clalit" Health Maintenance Organization (HMO) and their infants born at "Soroka" University Medical Center (SUMC) between 2001-2018. Cases are defined as term infants born with PDA diagnosed by echocardiography and registered in the post-delivery discharge form. Each case was matched with four term newborns without PDA diagnosis. Exposure window was defined by the timing of first purchase of H2RA or PPI during pregnancy and based on information from a computerized medication database (Clalit HMO, SUMC) Results. PDA was diagnosed in 1,884 term infants (4.9%). Characteristics included a significantly higher percentage of lack of prenatal care, cesarean section, in vitro fertilization, polyhydramnios, oligohydramnios, Apgar 1 minute <5, and prenatal exposure to H2RA (OR4.18) and PPIs (OR3.50) (all p<0.001). PDA association with exposure window was similar in each trimester (1.5-2%) for both H2RA and PPI. PDA Incidence in term infants in our population was greater than previously reported. PPI and H2RA are both anti-acids with different mechanisms of action. The similar OR for exposure to one as well as the other, and the lack of influence of the initial exposure period, are compatible with bias.

The effect of advanced age on peri- and post-operative complications following pelvic floor repair surgeries.

To assess whether advanced age is a risk factor for complications following pelvic organ prolapse (POP) repair surgeries using the Clavien-Dindo classification system. In this retrospective cohort study, 260 women who had undergone POP repair surgery at the Soroka University Medical Center (SUMC) between the years 2014-2019 were included. A univariate analysis was conducted to compare the demographical, clinical, obstetrical and operative characteristics of patients by age group (younger or older than 70years). We performed a similar analysis to assess for the possible association between several variables and post-operative complications. Variables that were found to be associated with post-operative complications (P < 0.2) were included in a multivariate analysis along with advanced age. During the 12months follow-up period, more than half of the women had experienced at least one post-operative complication. Minor complications (grades 1-2 according to the Clavian-Dindo classification system) were the most common. One woman had died during the follow-up period, and none had experienced organ failure (grade 4). Hysterectomy, as part of POP surgery, was found to be significantly associated with post-operative complications. Additionally, grandmultiparity (> 5 births) showed a tendency towards an increased risk for post-operative complications, however this reached only borderline significance. We found no association between advanced age and post-operative complications. POP repair surgeries are safe for women of all ages. Major complications (grades 3-5) are rare in all age groups. Although advanced age was associated with a higher prevalence of comorbidity and a higher grade of prolapse, no significant difference in the post-operative complications was found between age groups. Concomitant hysterectomy at the time of POP repair surgery is a risk factor for post-operative complications.

Epidemiological, clinical, and pathological characteristics of invasive breast cancer in Bedouin and Jewish women in southern Israel: a retrospective comparative study

BackgroundInvasive breast cancer (IBC) is a leading cause of cancer-related death among women in Israel, regardless of ethnicity. This study compared IBC epidemiological, clinical, and pathological characteristics in Bedouin and Jewish patients in southern Israel.MethodsMedical records of 1514 Jewish and 191 Bedouin women with IBC treated at Soroka University Medical Center between 2014 and 2021 were analyzed retrospectively. Baseline measures and tumor characteristics were compared between groups. Overall survival (OS) and disease-free survival (DFS) were analyzed using log-rank test. Multivariate analysis was performed using the Cox proportional hazard model.ResultsBedouin patients exhibited a significantly younger age at diagnosis (median 48 vs. 62 years, p < 0.001), larger tumor size (median 2.5 vs. 2.13 cm, p < 0.001), and higher metastasis rate (18.8% vs. 12.7%, p = 0.03) compared to Jewish patients. In early-stage (non-metastatic) disease, Jewish and Bedouin patients had comparable overall survival (OS) rates (127 vs. 126 months, p = 0.2), consistent across stages 1 to 3. However, among patients with metastatic disease, Bedouins exhibited significantly longer OS (76.6 vs. 37.8 months, p = 0.006). Disease-free survival (DFS) showed no ethnic differences (not reached vs. 122 months, p = 0.31). There were no significant differences in OS between Bedouin and Jewish patients undergoing various treatment modalities for early-stage disease: surgery, adjuvant radiotherapy, chemotherapy, and systemic neoadjuvant therapy.ConclusionBreast cancer among Bedouin women in southern Israel manifests at a younger age, with larger tumors and more advanced stages than in Jewish women. However, recent data indicate no differences in OS and DFS between the ethnic groups despite past disparities in prognosis.

Chronic Hypertension in Pregnancy and Placenta-Mediated Complications Regardless of Preeclampsia.

The prevalence of chronic hypertension in women of reproductive age is on the rise mainly due to delayed childbearing. Maternal chronic hypertension, prevailing prior to conception or manifesting within the early gestational period, poses a substantial risk for the development of preeclampsia with adverse maternal and fetal outcomes, specifically as a result of placental dysfunction. We aimed to investigate whether chronic hypertension is associated with placenta-mediated complications regardless of the development of preeclampsia in pregnancy. This was a population-based, retrospective cohort study from 'Soroka' university medical center (SUMC) in Israel, of women who gave birth between 1991 and 2021, comparing placenta-mediated complications (including fetal growth restriction (FGR), placental abruption, preterm delivery, and perinatal mortality) in women with and without chronic hypertension. Generalized estimating equation (GEE) models were used for each outcome to control for possible confounding factors. A total of 356,356 deliveries met the study's inclusion criteria. Of them, 3949 (1.1%) deliveries were of mothers with chronic hypertension. Women with chronic hypertension had significantly higher rates of all placenta-mediated complications investigated in this study. The GEE models adjusting for preeclampsia and other confounding factors affirmed that chronic hypertension is independently associated with all the studied placental complications except placental abruption. Chronic hypertension in pregnancy is associated with placenta-mediated complications, regardless of preeclampsia. Therefore, early diagnosis of chronic hypertension is warranted in order to provide adequate pregnancy follow-up and close monitoring for placental complications, especially in an era of advanced maternal age.

New definitions, old complications: The association between duration of transition from latent to active labor and adverse obstetrical outcomes.

To explore the relationship between the duration of transition from latent to active labor and various obstetric, maternal, fetal, and neonatal outcomes. A retrospective cohort study was conducted on term, singleton deliveries at Soroka University Medical Center from 2013 to 2018. Data were extracted from electronic medical records. The exposure variable was defined as prolonged transition, which was itself defined as the upper 10th centile of dilation duration from 4 to 6 cm. Clinical and demographic characteristics were compared using χ2 test. Multivariate logistic regression was used to estimate the contribution of a prolonged transition with each adverse outcome adjusting for potential confounders. In all, 12 104 deliveries met the inclusion criteria. The mean ± standard deviation of duration of dilation from 4 to 6 cm was 03:07:58 ± 03:03:42 (hours:minutes:seconds). Progress curves varied significantly among patients with different obstetrical and demographic characteristics. Prolonged transition was significantly linked to an increased risk of cesarean delivery (adjusted odds raito 2.607, 95% confidence interval 2.171-3.130, area under the curve 0.689) and higher rates of maternal and neonatal morbidity. Patients experiencing transition phases exceeding the 90th centile faced an elevated risk of cesarean delivery and postpartum complications. Future studies should focus on interventions during the transition phase to improve pregnancy outcomes and enhance patient safety.

Second-versus first-born twin: comparison of short- and long-term outcomes.

An ancient description of the competition between twins for first breath is found in the biblical story of Jacob and Esau (Genesis 25:26) when Jacob pulled his older brother's heel in the hope of becoming firstborn but to no avail. In this study, we sought to evaluate the short and long-term outcomes of twin pairs, comparing between the second- and first-born twin. A population-based cohort study, including dichorionic twin deliveries occurring between the years 1991 and 2021 at Soroka University Medical Center. A General estimation equation (GEE) was applied to adjust for confounders. The incidence of offspring's hospitalizations due to various medical conditions was compared. Kaplan-Meier survival analyses compared cumulative morbidity. Cox proportional hazards models were used to control for confounders. 5507 twin deliveries met the inclusion criteria. Second-born twins had higher rates of cesarean deliveries, statistically significant in the GEE multivariable analysis. More first-twin fetuses were experiencing non-reassuring fetal heart rate patterns, although other obstetrical outcomes as well as mortality rates were comparable between groups. Second twins weighed lower than their older sibling (mean difference 33g) and were more frequently SGA and low birthweight (1500-2500g); (p < 0.05). Later during childhood, offspring of twin deliveries experienced notable morbidity due to infectious (23.8-24.1%), respiratory (10.5-10.9%), neurological (7.0-7.8%) and cardiovascular pathologies (1.7-1.9%) during childhood, that was unaffected by birth order. Other than birthweight differences, the birth order of dichorionic twins is not associated with adverse neonatal health indices, nor does it predict excess risk for morbidity during childhood.

The impact of maternal hyperemesis gravidarum on early childhood respiratory morbidity.

Lung maldevelopment due to in-utero events may potentially cause respiratory morbidity during childhood. Maternal nutritional status during pregnancy is critical for lung development. This study is contributing to the understanding of the interplay between maternal nutrition status during pregnancy, fetal lung development and the risk for respiratory diseases in early life. To investigate the association between maternal hyperemesis gravidarum (HG) during pregnancy and respiratory morbidity in the offspring's early childhood. This is a retrospective population-based cohort study that included all singleton term deliveries at Soroka University Medical Center (SUMC) between 1991 and 2021. Preterm deliveries (<37 gestational week), perinatal deaths, multiple gestations, and children with congenital malformations or chromosomal abnormalities were excluded. The main outcomes measured were offspring's hospitalizations due to pneumonia, acute bronchiolitis, asthma, or wheezing. Overall 232,476 deliveries were included in the study, of which 3227 women (1.4%) were diagnosed with HG. Offspring in the HG group exhibited significantly higher rates of respiratory morbidity, including asthma (OR = 1.36, 95% CI1.22-1.36, p < .001), acute bronchiolitis (OR = 1.38, 95% CI1.21-1.59, p < .001), and pneumonia (OR = 1.2, 95% CI1.12-1.48, p < .001). An inverse correlation between multivariate adjusted-hazard ratios for asthma and pneumonia with offspring's age was noted. This study provides evidence of a potential association between maternal HG during pregnancy and increased risk of respiratory morbidity in offspring's early childhood. Maternal nutritional status during pregnancy plays a crucial role in lung development, affecting respiratory health in childhood.

Examining the relationship between autism spectrum disorder in children whose mother had labour epidural analgesia for their birth: A retrospective cohort study.

Controversy exists regarding the association between autism spectrum disorder (ASD) in children whose mother had labour epidural analgesia for their birth, as the few existing investigations have reported mixed findings. This study aims to evaluate the possibility of an association in our heterogeneous population. A retrospective population-based cohort study. Vaginal deliveries that took place between the years 2005 and 2017 at Soroka University Medical Center, a tertiary referral hospital in Israel, and a follow-up on the incidence of ASD in the children. A hundred and thirty-nine thousand, nine hundred and eighty-one labouring patients and their offspring. The incidence of children diagnosed with ASD (both hospital and community-based diagnoses) was compared based on whether their mothers had received labour epidural analgesia during their labour. A Kaplan-Meier survival curve compared cumulative incidence of ASD. A Cox proportional hazards model was used to control for relevant confounders. Labour epidural analgesia was administered to 33 315 women. Epidural analgesia was more common among high-risk pregnancy groups (including pregnancies complicated with diabetes mellitus, hypertensive disorders, intrauterine growth restriction, and oligohydramnios; P < 0.001). In a Cox proportional hazards model, the association between epidural analgesia during labour and ASD in the children lost statistical significance following adjustment for confounders such as maternal age, gestational age, hypertensive disorders, diabetes mellitus, and ethnicity [adjusted hazard ratio = 1.13, 95% confidence interval (CI), 0.96 to 1.34, P = 0.152]. In our population, after adjusting for confounders, epidural analgesia is not independently associated with autism spectrum disorder in the children. These findings enhance our knowledge regarding the safety of epidural analgesia and enable patients to make informed decisions about their pain relief techniques during labour.

The Correlation between Fetal Monitor Decelerations Area and Neonatal Cord pH among Preeclamptic parturient: an Automated Approach to a Clinical Challenge.

To examine whether a correlation exists between electronic fetal monitoring (EFM) in the final 120 minute prior to delivery and neonatal cord blood pH among parturients with preeclampsia. A retrospective cohort study of parturients with term and near-term preeclampsia who delivered at Soroka University Medical Center between 2013 and 2020 was conducted. EFM tracings, demographical data, and obstetrical outcomes were retrieved from the patients' electronic medical records. Using MATLAB program, area under the curve (AUC) measurements were applied. Correlation was calculated using the Spearman's correlation coefficient. EFM of 88 parturients with preeclampsia were assessed. A significant negative correlation was demonstrated between cord blood pH and the decelerations AUC, total decelerations duration, and deceleration depth. No correlation was demonstrated between area over the curve (acceleration) and cord blood pH. In a multivariate linear regression, total deceleration AUC was found independently negatively associated with cord blood pH (beta = -0.264, p = 0.011) controlling for second stage of labor duration and induction of labor. Among parturients with preeclampsia, EFM indices may assist in the diagnosis of fetal acidemia. Further studies are needed to strengthen and establish the use of electronic EFM in the management of labor and delivery. · A negative correlation was demonstrated between cord blood pH and the decelerations AUC.. · Total deceleration AUC was found independently negatively associated.. · Among parturients with preeclampsia, EFM indices may assist in the diagnosis of fetal acidemia..

Severity of a Vipera palaestinae envenomation objective findings associated with a complicated hospitalization course following a Vipera palaestinae bite

The most common snake in Israel, responsible for most snakebites is Vipera palaestinae (VP). Envenomation signs and symptoms vary from local manifestations to systemic reactions that may end with death. Antivenom treatment, given to high-risk patients, reduces complications and mortality but carries risks. As of now, there is no standardized protocol for adults bitten by VP based on objective clinical and laboratory findings. We conducted A retrospective analysis of 159 patients admitted to two large tertiary care institutions in the center (Hadassah University Medical Center) and south (Soroka University Medical Center) of Israel with Vipera palaestinae bites during 1990–2017. Epidemiological and clinical data were extracted, and the patients were divided into two groups based on hospitalization time (over or under 48 h). 159 patients were included in this study. The average hospitalization time was 66.1 h, with 49.7% of patients admitted over 48 h. The main factors that statistically correlated with a longer hospitalization time were: Male gender, lower extremity bite, platelets lower than 150 K at presentation, leukocyte count of over 10 K at presentation and elevated D-Dimer levels. This study provides factors which are associated with a severe VP envenomation. These clinical or laboratory findings (along with accompanying clinical symptoms) are associated with a higher risk of a prolonged hospitalization with more complications and may require a more intensive treatment and monitoring.

Long term respiratory morbidity of cesarean-delivered second twin compared to their vaginally-delivered sibling: A retrospective population-based cohort study.

Offspring born via cesarean delivery (CD) may be more prone to develope long-term respiratory diseases, compared to those delivered vaginally (VD). In this study, we compared the rates of respiratory diseases between first twins VDand second twins delivered via CD. This was a retrospective database study. All twin deliveries encompassed at the Soroka University Medical Center, a large tertiary hospital in southern Israel, between 1991 and 2020, in which the first twin was VDand the second via CD were included. Respiratory diseases included respiratory tract diseases such as bronchiolitis and bronchial asthma. The cumulative incidence of respiratory diseases was compared between the twins using Kaplan-Meier survival analysis and multivariable Cox models to adjust for confounding variables. A total of 395,408 deliveries occurred during the study period, with 13,402 (3.4%) of all deliveriesbeing twins. Of these, 184 (1.4%) were first twins VDand second twins delivered via CD. The second CD twin was more likely to have a non-reassuring fetal heart rate pattern and an Apgar score less than 7 at 5 min. No other differences were found between the siblings. The incidence of long-term respiratory diseases was not statistically different between the CD and VD siblings (7.6% vs. 9.4%, respectively; OR = 0.54; 95%CI: 0.23-1.26). Similarly, the cumulative incidence of respiratory diseases was not statistically different (Kaplan-Meier, log-rank, p = .59), and in the multivariable analysis which adjusted for birthweight and fetal distress during delivery (adjusted hazard ratio = 1.06; 95%CI: 0.43-26.25). While the immediate outcomes for the CD twin were slightly worse compared to the VD twin, there was no difference in long-term respiratory diseases between the siblings.

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

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. 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. 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. 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.

Is epidural analgesia an independent risk factor for OASIS? A population-based cohort study.

To evaluate whether epidural analgesia is an independent risk factor for OASIS. A population-based cohort study including all women who delivered by spontaneous vaginal delivery or by instrumental delivery beyond 24 weeks gestation was conducted. Deliveries occurred between 1988 and 2016 at a large university tertiary medical center. Women with multiple gestations and those lacking prenatal care were excluded from the analysis. During the study period, 252,542 women delivered at the Soroka University Medical Center and met the inclusion criteria. Of these, 583 (0.23%) were diagnosed with OASIS. Women with OASIS were more likely to be younger, nulliparous, with suspected fetal macrosomia, had higher rates of labor induction and vacuum extraction delivery, higher rates of conceiving after infertility treatments, more advanced gestational age at delivery, higher mean birth weight, higher rates of post-partum hemorrhage and need for blood transfusions. Use of epidural analgesia during pregnancy was significantly high among the OASIS group. Rates of episiotomy were not significantly different between the groups. Using a multimodal logistic regression model, after controlling for vacuum delivery, large for gestational age, nulliparity, gestational age, ethnicity, maternal age, induction of labor, fertility treatments, non-reassuring fetal heart rate and non-progressive second stage of labor, epidural analgesia was found to be significantly associated with OASIS. Epidural analgesia was found to be an independent risk factor for OASIS in our population.

Evaluation of Foreign body aspiration score (FOBAS) in children- A retrospective cohort study.

Foreign Body Aspiration (FBA) is a common medical emergency among young children, but the evaluation and management of a suspected FBA case can vary across physicians and centers. We aimedto identify which clinical, laboratory, and radiological findings can predict FBA in children and to evaluate a clinical score to improve FBA prediction. This isa retrospective cohort study of patients aged 0-18years admitted to Soroka University Medical Center between 2010 and 2020 with suspected FBA. All patients underwent flexible bronchoscopy and were divided into positive and negative FBA groups. A newly developed foreign body aspiration score (FOBAS), based on medical history, physical examination, and chest X-ray findings, was evaluated for its predictability. The study included 412 children (median age 21months, 56.8% females), of whom 154 (37.4%) had FBA and 258 (62.6%) did not. Multivariate regression analysis showed exposure to nuts/seeds, unilateral wheezing or decreased breath sounds, stridor, and suggestive findings on chest X-ray were significant risk factors for FBA (OR [95%CI] -1.994[1.290-3.082], 1.487[1.206-1.832], 1.883 [1.011-3.509] and 2.386[1.917-2.970], respectively). However, a choking episode, acute cough, and absence of fever and rhinorrhea did not predict FBA. FOBAS showed an increased risk of FBA for each additional point of the score, with an odds ratio of 1.572 (95% CI-1.389-1.799). Conclusion: FOBAS is a good predictor for the presence of FBA in children. Once prospectively validated, FOBAS could aid in decision-making at the emergency department, enabling more standardized care, reducing unnecessary procedures, and leading to better clinical outcomes. What is Known: •The evaluation and management of a child with suspected foreign body aspiration (FBA) vary acrossphysicians and centers, without a consensus regarding the indications and criteria for performing bronchoscopy. • Flexible bronchoscopy is the standard procedure for the diagnosis and sometimes treatment of FBA inchildren, but it may hold potential complications. What is New: • We propose a newly developed foreign body aspiration score (FOBAS), based on medical history, physical examination, and chest X-ray findings, for the prediction of FBA in children at the emergency department. • The FOBAS is a good predictor of FBA in children. The score enables more standardized care and may reduce unnecessary procedures.

Blood Stream Infections in Burns: A 14-Year Cohort Analysis.

Blood stream infections are a significant cause of morbidity and mortality in burns, and pathogen identification is important for treatment. This study aims to characterize the microbiology of these infections and the association between the infecting pathogen and the hospitalization course. We conducted a cohort study that included records of burn patients treated at the Soroka University Medical Center between 2007-2020. Statistical analysis of demographic and clinical data was performed to explore relationships between burn characteristics and outcomes. Patients with positive blood cultures were divided into four groups: Gram-positive, Gram-negative, mixed-bacterial, and fungal. Of the 2029 burn patients hospitalized, 11.7% had positive blood cultures. The most common pathogens were Candida and Pseudomonas. We found significant differences in ICU admission, need for surgery, and mortality between the infected and non-infected groups (p < 0.001). Pathogen groups differed significantly mean TBSA, ICU admission, need for surgery, and mortality (p < 0.001). Multivariate analysis showed flame (OR 2.84) and electric burns (OR 4.58) were independent risk factors for ICU admission and surgical intervention (p < 0.001). Gram-negative bacterial infection was found to be an independent predictor of mortality (OR = 9.29, p < 0.001). Anticipating specific pathogens which are associated with certain burn characteristics may help guide future therapy.

Can Dialysis Patients Identify and Diagnose Pulmonary Congestion Using Self-Lung Ultrasound?

With the recent developments in automated tools, smaller and cheaper machines for lung ultrasound (LUS) are leading us toward the potential to conduct POCUS tele-guidance for the early detection of pulmonary congestion. This study aims to evaluate the feasibility and accuracy of a self-lung ultrasound study conducted by hemodialysis (HD) patients to detect pulmonary congestion, with and without artificial intelligence (AI)-based automatic tools. This prospective pilot study was conducted between November 2020 and September 2021. Nineteen chronic HD patients were enrolled in the Soroka University Medical Center (SUMC) Dialysis Clinic. First, we examined the patient's ability to obtain a self-lung US. Then, we used interrater reliability (IRR) to compare the self-detection results reported by the patients to the observation of POCUS experts and an ultrasound (US) machine with an AI-based automatic B-line counting tool. All the videos were reviewed by a specialist blinded to the performer. We examined their agreement degree using the weighted Cohen's kappa (Kw) index. A total of 19 patients were included in our analysis. We found moderate to substantial agreement between the POCUS expert review and the automatic counting both when the patient performed the LUS (Kw = 0.49 [95% CI: 0.05-0.93]) and when the researcher performed it (Kw = 0.67 [95% CI: 0.67-0.67]). Patients were able to place the probe in the correct position and present a lung image well even weeks from the teaching session, but did not show good abilities in correctly saving or counting B-lines compared to an expert or an automatic counting tool. Our results suggest that LUS self-monitoring for pulmonary congestion can be a reliable option if the patient's count is combined with an AI application for the B-line count. This study provides insight into the possibility of utilizing home US devices to detect pulmonary congestion, enabling patients to have a more active role in their health care.
