Purpose: To provide a comprehensive report of the experience gained in the prenatal treatment of congenital diaphragmatic hernia (CDH) using fetoscopic endoluminal tracheal occlusion (FETO) following its implementation at a newly established specialized fetal medicine center., Methods: Mothers of fetuses with severe CDH were offered prenatal treatment by FETO., Results: Between 2018 and 2021, 16 cases of severe CDH underwent FETO. The median gestational age (GA) at balloon insertion was 28.4 weeks (IQR 27.8-28.6). The median GA at delivery was 37 weeks (IQR 34.4-37.8). The survival rate was 8/16 cases (50%). None of the survivors required home oxygen therapy at 6 months of age. Comparison between the survivors and deceased showed that survivors had balloon insertion 1 week earlier (27.8 vs. 28.4 weeks, p = 0.007), a higher amniotic fluid level change between pre- to post-FETO (3.4 vs 1.3, p = 0.024), a higher O/E LHR change between pre- to post-FETO (50.8 vs. 37.5, p = 0.047), and a GA at delivery that was 2 weeks later (37.6 vs. 35.4 weeks, p = 0.032)., Conclusions: The survival rate at 6 months of age in cases of severe CDH treated with FETO in our center was 50%. Our new fetal medicine center matches the performance of other leading international centers., (© 2023.

Adrenal gland infection is a clinical entity of great importance, but it is a largely unrecognized pathology. Immunosuppressed individuals are at a higher risk of presentation. Herein, we describe a young female patient, recently diagnosed with HIV, who presented with severe sepsis due to methicillin-resistant Staphylococcus aureus, associated with a left adrenal abscess. She was initially treated with antibiotics; however, due to the persistence of the systemic inflammatory response and bacteremia, endoscopic ultrasound-guided drainage was performed. This procedure was successful in resolving the clinical situation. Endoscopic ultrasound-guided adrenal gland drainage can be a safe, efficacious, and minimally invasive option for managing antibiotic-refractory adrenal abscesses in immunosuppressed patients.

To date, there is no overarching proposition for the ontogenetic-neurobiological basis of self-regulation. This paper suggests that the balanced self-regulatory reaction of the fetus, newborn and infant is based on a complex mechanism starting from early brainstem development and continuing to progressive control of the cortex over the brainstem. It is suggested that this balance occurs through the synchronous reactivity between the sympathetic and parasympathetic systems, both which originate from the brainstem. The paper presents an evidence-based approach in which molecular excitation-inhibition balance, interchanges between excitatory and inhibitory roles of neurotransmitters as well as cardiovascular and white matter development across gestational ages, are shown to create sympathetic-parasympathetic synchrony, including the postnatal development of electroencephalogram waves and vagal tone. These occur in developmental milestones detectable in the same time windows (sensitive periods of development) within a convergent systematic progress. This ontogenetic stepwise process is termed "the self-regulation clock" and suggest that this clock is located in the largest connection between the brainstem and the cortex, the corticospinal tract. This novel evidence-based new theory paves the way towards more accurate hypotheses and complex studies of self-regulation and its biological basis, as well as pointing to time windows for interventions in preterm infants. The paper also describes the developing indirect signaling between the suprachiasmatic nucleus and the corticospinal tract. Finally, the paper proposes novel hypotheses for molecular, structural and functional investigation of the "clock" circuitry, including its associations with other biological clocks. This complex circuitry is suggested to be responsible for the developing self-regulatory functions and their neurobehavioral correlates.

Preterm infants, age-corrected for prematurity, score on average, 10 points lower on IQ tests than full-term infants tested at comparable ages. This review focuses on the potential contribution of the hypothalamus to cognitive neuro-regulatory development in preterm infants through its bidirectional neural connections with the prefrontal cortex and its neuroendocrine activity. It aims to clarify the central role of the hypothalamus in preterm high stress situations and in influencing cognitive development via its connectivity to the cerebral cortex. The review further evaluates epigenomic sensitivity to environmental inputs. Recent results suggest that an optimal range of DNA methylations (via a continuous process of decreasing levels of receptor methylations that are too high, and increasing levels that are too low) appears necessary in order to reach an adaptive level of receptor availability. Several studies have demonstrated amelioration of preterm infants' stress while in the Newborn Intensive Care Unit (NICUs) and following discharge. The authors postulate that feedback mechanisms and correction signals are the basis for a hypothalamic homeostatic modulating function, a "hypothalamic resistance response", which may account for the stress reduction brought about by in- and post-NICU early interventions and their results of promoting self-regulation and cognition., Competing Interests: None., (© 2021 The Authors.)

Objectives: Neonatal late-onset sepsis work-up is a frequent occurrence in every neonatal department. Blood cultures are the diagnostic gold standard, however, a negative culture prior to 48-72 h is often considered insufficient to exclude sepsis. We aimed to develop a decision tree which would enable exclusion of late-onset sepsis within 24 h using clinical and laboratory variables. Study Design: Infants evaluated for late-onset sepsis during the years 2016-2019, without major malformations, in a tertiary neonatal center were eligible for inclusion. Blood cultures and clinical and laboratory data were extracted at 0 and 24 h after sepsis work-up. Infants with bacteriologically confirmed late-onset sepsis were compared to matched control infants. Univariate logistic regression identified potential risk factors. A decision tree based on Chi-square automatic interaction detection methodology was developed and validated. Results: The study cohort was divided to a development cohort (105 patients) and a validation cohort (60 patients). At 24 h after initial evaluation, the best variables to identify sepsis were C-reactive protein > 0.75 mg/dl, neutrophil-to-lymphocyte ratio > 1.5 and sick-appearance at 24 h. Use of these 3 variables together with blood culture status at 24 h, enabled identification of all infants that eventually developed sepsis through the decision tree model. Our decision tree has an area under the receiver operating characteristic curve of 0.94 (95% CI: 0.90-0.98). Conclusions: In non-sick appearing infants with a negative blood culture at 24 h and normal laboratory values, sepsis is highly unlikely and discontinuing antibiotics after 24 h is a viable option., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Goldberg, Sokolover, Bromiker, Amitai, Chodick, Scheuerman, Ben-Zvi and Klinger.)

Introduction: gastric varices hemorrhage is a severe complication of portal hypertension, with high mortality rates and few management alternatives, especially when there is a contraindication to transjugular intrahepatic portosystemic shunts (TIPS). The usual therapeutic options are the injection of cyanoacrylate, the insertion of coils or both. Hydrocoils are special coils coated with different types of expandable hydrogel polymers conventionally used in neurovascular interventionism. They allow rapid occlusion of vessel, forming a mesh that favors the local formation of thrombus and the development of a neointima on the gel cover. We consider the use of endoscopic ultrasound (EUS) guided hydrocoil insertion in gastric varices, without using cyanoacrylate., Objective: this study aimed to evaluate the safety and effectivity of the application of EUS-guided hydrocoils in patients with gastric varices hemorrhage with TIPS contraindication., Material and Methods: this was a retrospective case series of four patients with TIPS contraindication after interventional radiologist evaluation. Linear echoendoscopes, fluoroscopy, 19G needles and hydrocoils (Azur®, Terumo) and Progreat® 3 Fr microcatheters were used. An interventional radiologist expert advised the procedures and endoscopic ultrasound confirmed the varix obliteration., Results: technical and clinical success occurred in all patients involved in this study. There were no adverse effects related to the procedure or endoscopic equipment damage., Conclusions: the application of EUS-guided hydrocoils can be a safe and effective method in the short term for gastric varices bleeding in patients who are not candidates for TIPS. Besides, a complete obliteration of the vascular lumen could occur and thus, dispense with the use of cyanoacrylate. Further studies are needed to corroborate these preliminary results.

Introduction: pancreatic insulinoma is a sporadic, usually benign, frequently solitary tumor that is smaller than 20 mm. When it is functioning, patients present with symptoms of hypoglycemia secondary to insulin hypersecretion. The diagnosis is clinical, with biochemical and radiological confirmation. Surgery is the management of choice, although endoscopic ultrasound-guided ablation is currently being developed., Material and Methods: we present a prospective case series of pancreatic insulinoma patients with symptoms of severe hypoglycemia, who were treated with endoscopic ultrasound-guided ethanol ablation as an alternative to surgical management., Results: technical and clinical success was achieved in all cases and there were no complications associated with the procedure., Conclusion: the treatment of symptomatic insulinoma by endoscopic ultrasound-guided ethanol ablation could be a safe and effective alternative to surgical management in non-surgical patients or those who refuse surgery.

We appreciate the interest shown in our article "Endoscopic ultrasound-guided fine-needle aspiration for splenomegaly and focal splenic lesion: is it safe, effective and necessary?", as well as the academic discussion raised by gastroenterology-ultrasound experts in the letter to the editor. In the discussion of our article, we mention that EUS-FNA is necessary and/or the first option in splenomegaly and/or small focal splenic lesions where percutaneous biopsy are limited, when difficulty accessing the focal splenic lesions, in obese patients and in those with ascites, recent abdominal surgery or a poor acoustic window.

Introduction: splenomegaly and/or focal splenic lesions (FSL) have limited histopathologic studies due to the risk posed by splenic punctures. Percutaneous biopsies with a fine needle are difficult, especially due to interposition of gases, ascites, obesity or a history of abdominal surgery. On the other hand, endoscopic ultrasound (EUS) takes advantage of the proximity of the gastric wall to the spleen in order to puncture and visualize the needle and its movements in real time., Objective: to describe the initial experience and results obtained with EUS-FNA in patients with splenomegaly or FSL., Materials and Methods: this was a descriptive observational study. EUS-FNA of the spleen was performed with a slow-pull technique, which avoided fanning with an average of 3 needle passes. Biopsies were sent in Cytorich RedTM solution for analysis by cytology and cell block., Results: punctures were performed in 15 patients (9 females) and the median age was 67 years (range 44-86). Patients studied due to an enlarged spleen or splenic FSL, in the context of fever of an unknown origin, adenopathies and abnormal weight loss were included. A conclusive diagnosis was achieved by EUS-FNA in 10 patients (66.7 %), 4 were large cell type B non-Hodgkin's lymphoma and one Hodgkin's lymphoma. There were no immediate or delayed complications related to the procedure., Conclusions: EUS-guided splenic punctures appear to be safe, effective and may be necessary in some clinical settings in order to complete the etiologic filiation of splenomegaly of an uncertain origin or FSL and to rule out malignancy.

Neonatal herpes simplex virus (HSV) infection is a life-threatening infection with high morbidity and mortality rates. Neonatal herpes, most commonly due to HSV type 2, is a multi-system disease; however, initial pulmonary presentation is extremely unusual. We describe an infant presenting with progressive respiratory distress, which was the dominant clinical feature of HSV infection during the first days of life. Sepsis work-up and antibiotic treatment were immediately initiated; however, antiviral treatment was not given until the infant's death. HSV type 1 was isolated in nasopharyngeal and endotracheal aspirates. HSV pneumonia should be considered in a newborn with respiratory deterioration not compatible with common neonatal respiratory diseases., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2019 Franck Kouadio and Gil Klinger.)

Sump syndrome (SS) is associated with choledocho-duodenostomy (CDD) dysfunction, which occurs due to accumulation of detritus, biliary mud and food remains in the suprapapillary distal common bile duct. The prevalence is low after CDD. Currently, biliary drainage endoscopic ultrasound (EUS)-guided with a lumen-apposing metal stent (LAMS) is a new minimally invasive alternative for biliary stenosis for patients in whom endoscopy retrograde cholangial-pancreatography (ERCP) is not feasible. CDD via EUS-guided LAMS is increasing. Thus, SS has become a potential associated complication that was previously unreported in the literature.

We present the case of a 79-year-old patient with multiple cardiovascular morbidities, classified as ASA III (American Society of Anesthesiology). An upper digestive endoscopy was performed due to chronic anemia and a subepithelial lesion was identified in the subcardial region of 30 x 25 mm, without other relevant findings.

Surgical management has been the main approach for enteral fistulae. This approach is usually complex due to comorbidities, a wasted nutritional state and anatomical difficulties related to prior multiple interventions. Therefore, endoscopic methods such as clips, self-expanding metal stent (SEMS) and recently, the over scope clip (OTSC®) are increasing in popularity and use. Herein, we present the case of a patient with a HIV infection who was admitted due to respiratory symptoms. Radiological and microbiological studies documented a tracheoesophageal fistula due to tuberculosis (TB) and cytomegalovirus (CMV) infection. Therefore, an esophageal fully-covered stent was placed, which migrated into the stomach. The thoracic surgeons considered an esophagectomy with gastric ascent and muscle patch in the trachea. However, due to his poor nutritional status and comorbidity, an OTSC was placed to treat the fistulae. The patient also received medical treatment with anti-tuberculotics and anti-retrovirals.

Aims: Metformin is used to treat type 2 diabetes, polycystic ovary syndrome associated infertility, and gestational diabetes. This study aims to evaluate the safety of metformin in early pregnancy., Method: We evaluated the risk of major birth defects and pregnancy losses in a cohort of pregnant women exposed to metformin during the first trimester for different indications relative to a matched unexposed reference group., Results: The risk of major birth defects was 5.1% (20/392) in pregnancies exposed to metformin during the first trimester and 2.1% (9/431) in the reference group [adjusted odds ratio (OR) 1.70; 95% CI 0.70-4.38]. Among metformin users, this risk was 7.8% (17/219) in patients with pre-gestational diabetes and 1.7% (3/173) in those without this diagnosis. Compared to the unexposed reference, the OR for metformin user with diabetes was 3.95 (95% CI 1.77-9.41) and for metformin with other indications it was 0.83 (95% CI 0.18-2.81). The risk of pregnancy losses (spontaneous abortions and stillbirths) was 20.8% in women on metformin during the first trimester and 10.8% in the reference group [adjusted hazard ratio (HR) 1.57; 95% CI 0.90-2.74]. The risks for women on metformin with and without pre-gestational diabetes were 24.0% and 16.8% respectively, with adjusted HR of 2.51 (95% CI 1.44-4.36) and 1.38 (95% CI 0.74-2.59) when compared to the reference., Conclusion: Pregnant women with pre-gestational diabetes on metformin are at a higher risk for adverse pregnancy outcomes than the general population. This appears to be due to the underlying diabetes since women on metformin for other indications do not present meaningfully increased risks., (© 2017 The British Pharmacological Society.)

Aims: The present study evaluates the effect of antenatal lamotrigine exposure, on short- and long-term paediatric outcome., Methods: The study included the children of 83 epileptic women treated with lamotrigine during pregnancy, at a tertiary medical centre between 2004-2014. All newborns were monitored for vital signs, congenital malformations and Finnegan score. In addition, the parents completed a questionnaire regarding their child's development and health up to the age of 12 years., Results: No major malformations were found in the newborns. None of the newborns had significant withdrawal symptoms by Finnegan score. The children were followed-up to the age of 12 years (56.6% were 6-12 years at the time of evaluation). There were no significant findings in the incidence of neurodevelopmental disorders., Conclusions: According to our experience, lamotrigine is generally safe for pregnancy use, associated with minimal short-term complications with no long-term effects on the outcome., (© 2017 The British Pharmacological Society.)

Neonatal hemochromatosis (NH) is an acute liver disease associated with both hepatic and extrahepatic iron deposition and is a leading cause of neonatal liver transplantation. The concept that NH is an alloimmune disease has led to the emergence of a new treatment approach utilizing exchange transfusion and intravenous immunoglobulin therapy. We present a two-day old neonate with progressive liver dysfunction who was diagnosed with NH. Magnetic resonance imaging confirmed tissue iron overload. Treatment with intravenous immunoglobulins and exchange transfusion led to rapid improvement in liver function. Follow-up physical examination at the age of 8 months showed normal development and near normal liver function. A repeat abdominal magnetic resonance scan at 8 months showed no signs of iron deposition in the liver, pancreas, or adrenal glands. The present report provides further support for the use of exchange transfusion and immunoglobulin therapy in NH and is the first to document resolution of typical iron deposition by magnetic resonance imaging.
