Background: Mild hyponatremia is frequently encountered in the pediatric emergency department (PED). Although usually of little clinical concern, its prognostic meaning as a possible marker of more severe disease has not yet been well established., Methods: We retrospectively analyzed data from children and adolescents who performed a blood sample with plasmatic sodium measurement on admission to the PED of IRCCS "Burlo Garofolo" Pediatric Hospital in Trieste, Italy, in 2019. We compared the rate, length of admissions and laboratory characteristics of patients with hyponatremia to those with normal sodium., Results: Among 807 subjects, hyponatremia (sodium < 135 mEq/L) was present in 17.6%, being mild (between 130 and 134 mEq/L) in 16.5%. Hyponatremic patients were younger, more frequently males, with an infection diagnosis, mainly of the respiratory tract and viral aetiology. They presented higher C-reactive protein (CRP) levels and erythrocyte sedimentation rates (ESR). Compared to normonatremic individuals, hyponatremic patients presented a higher risk of underlying infection (aOR 2.02; 95%CI 1.33-3.08), hospital admission (aOR 1.72; 95%CI 1.06-2.48), and a hospital stay of > 5 days (aOR 1.99; 95%CI 1.03-3.85). When considering only subjects with mild hyponatremia, we found similar results., Conclusion: Hyponatremia and mild hyponatremia in the PED are associated with an increased admission rate and extended hospital stays. Mild hyponatremia should be considered a warning sign for a possibly more serious condition., (© 2023. The Author(s).)

Background: Functional gastrointestinal disorders (FGIDs) are chronic and recurrent disorders, which affect up to 23% of children and adolescents and represent 50% of gastroenterological accesses. The association between FGIDs diagnosed at paediatric age and the onset of migraine or headache and neuropsychiatric diseases in adolescence and adulthood is widely reported in the literature. However, there is still limited knowledge about the long-term prognosis and risk factors for neuropsychiatric pathologies and other comorbidities., Aim: The aim is to assess the prevalence and persistence of FGIDs as well as the occurrence of migraine or headache and neuropsychiatric disorders in a cohort of patients diagnosed with FGIDs 15 years ago compared with a control group of peers., Materials and Methods: We enrolled a group of patients diagnosed with FGIDs at paediatric age, at least 10 years ago (FGIDs group, n = 79; median age 23), and control subjects (control group, n = 201; median age 23). In both groups, an online questionnaire created explicitly for the study was submitted in order to investigate the presence of chronic intestinal diseases, migraine, headache or neuropsychiatric disorders., Results: 45.6% (36 out of 79) of patients previously diagnosed with FGIDs still suffer from FGIDs versus 12% (24 out of 201) of healthy controls ( p < 0.0001). The prevalence of chronic organic gastrointestinal disorders was comparable in the two groups (2.5% in FGIDs group versus 1% in healthy group, p = 0.3). Thirty-three percent (26 out of 79) of FGIDs patients reported headache or migraine versus 13% (26 out of 201) of healthy peers ( p < 0.001). No differences were found regarding the prevalence of anxiety and depression., Conclusion: The outcome at 15 years of FGIDs was characterized by a high prevalence of persisting functional symptoms along with a significant incidence of headaches and migraines. Abbreviation: FGIDs: Functional gastrointestinal disorders; IBS: Inflammatory Bowel Syndrome.

Background: Neonates with congenital urinary tract dilatation (UTD) may have an increased risk of urinary tract infections (UTI). At present, the management of these patients is controversial and the utility of continuous antibiotic prophylaxis (CAP) remains uncertain as the literature presents contradicting evidence. The aim of this observational study was to assess UTI occurrence in children with prenatal diagnosis of urinary collecting system dilatation without antibiotic prophylaxis., Methods: Between June 2012 and August 2016, we evaluated the incidence of UTI and the clinical and ultrasonography evolution in 407 children with a prenatally diagnosed UTD. All subjects underwent two prenatal ultrasounds scans (USs) at 20 weeks and 30 weeks of gestation and within 1 month of birth. Patients with a confirmed diagnosis of UTD underwent US follow-up at 6, 12 and 24 months of life. According to the UTD classification system stratify risk, after birth UTD were classified into three groups: UTD-P1 (low risk group), UTD-P2 (intermediate risk group), and UTD-P3 (high risk group). Voiding cystourethrogram was performed in all patients who presented a UTI and in those with UTD-P3. No patient underwent CAP., Results: Postnatal US confirmed UTD in 278 out of 428 patients with the following rates: UTD-P1 (126), UTD-P2 (95) and UTD-P3 (57). During postnatal follow-up, 6.83% patients presented a UTI (19 out of 278). Eleven out of 19 had vesicoureteral reflux (VUR), and other four were diagnosed with obstructive uropathy and underwent surgical correction. Five patients presented a UTI reinfection., Conclusion: The occurrence of UTI in patients with urinary collecting system dilatation was low. The recent literature reports an increased selection of multirestistant germs in patients with VUR exposed to CAP. This study constitutes a strong hint that routine continuous antibiotic prophylaxis could be avoided in patients with UTD., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: Primary adrenal insufficiency (PAI) in children is an uncommon but severe condition which can be either inherited or acquired. It consists in clinical manifestation of defective production or ineffective action of endogenous glucocorticoids; deficiency in mineralocorticoids and adrenal androgens may coexist. Diagnosis of PAI in children and young people can be challenging; while adrenal crisis (acute decompensation) is a life-threatening condition, with patient presenting with characteristic features of hypoglycemia, hypotension, collapse and coma, chronic adrenal insufficiency may present with vague and non-specific symptoms, making the diagnosis more difficult. 1 Gastroenteritis and Syndrome of Inappropriate Secretion of Antidiuretic hormone (SIADH) are the most frequent reported misdiagnosis in patients with adrenal insufficiency (AI). While intravenous fluid replacement in the suspect of a gastroenteritis would be beneficial, a SIADH misdiagnosis can be harmful since the treatment of this condition is based primarily on fluid restriction., Case Presentation: We report the case of a child admitted to the emergency department whose condition was ultimately diagnosed as autoimmune adrenal insufficiency after few hours of inappropriate fluid restriction following a SIADH misdiagnosis., Conclusions: AI is a rare condition in children and the diagnosis can be challenging. A missed diagnosis of AI or an inadequate treatment may cause severe complications, especially if a SIADH is erroneously diagnosed. Emergency physicians and pediatricians should be familiar with this diagnosis to enhance early recognition of this potentially life-threatening condition.

Purpose: Venipuncture generates anxiety and pain in children. The primary aim of the study was to evaluate two non-pharmacological techniques, vibration combined with cryotherapeutic topical analgesia by means of the Buzzy® device and animated cartoons, in terms of pain and anxiety relief during venipuncture in children., Designs and Methods: 150 children undergoing venipuncture were randomized into four groups: the 'no method' group, the Buzzy® device group, the animated cartoon group and the combination of Buzzy® and an animated cartoon group. Children's pain and anxiety levels along with parents' and nurses' anxiety levels were evaluated by means of validated grading scales., Results: Overall children's pain increased less in the non-pharmacological intervention groups as compared to the group without intervention. Notably, the difference was statistically significant in the animated cartoon group for children's perception of pain. Children's anxiety and parents' anxiety decreased more in non-pharmacological interventions groups as compared to the group without intervention., Conclusions: The study showed the effectiveness of non-pharmacological methods of pain management during venipuncture. Notably, distraction with animated cartoons was superior in terms of children's perception of pain when compared to Buzzy®, and to the combination of cartoons and Buzzy®. Buzzy® was significantly effective at the secondary analysis for children younger than 9. Children's and parents' anxiety is decreased by non-pharmacological methods. Furthermore, nurses' involvement in pediatric care can be enhanced., Practice Implications: Non-pharmacological methods of pain management during venipuncture represent an easy way to achieve an increased level of compliance among children and parents., (Copyright © 2018 Elsevier Inc.

Background. Pneumothorax (PTX) still remains a common cause of morbidity in critically ill and ventilated neonates. At the present time, lung ultrasound (LUS) is not included in the diagnostic work-up of PTX in newborns despite of excellent evidence of reliability in adults. The aim of this study was to compare LUS, chest X-ray (CXR), and chest transillumination (CTR) for PTX diagnosis in a group of neonates in which the presence of air in the pleural space was confirmed. Methods. In a 36-month period, 49 neonates with respiratory distress were enrolled in the study. Twenty-three had PTX requiring aspiration or chest drainage (birth weight 2120 ± 1640 grams; gestational age = 36 ± 5 weeks), and 26 were suffering from respiratory distress without PTX (birth weight 2120 ± 1640 grams; gestational age = 34 ± 5 weeks). Both groups had done LUS, CTR, and CXR. Results. LUS was consistent with PTX in all 23 patients requiring chest aspiration. In this group, CXR did not detect PTX in one patient while CTR did not detect it in 3 patients. Sensitivity and specificity in diagnosing PTX were therefore 1 for LUS, 0.96 and 1 for CXR, and 0.87 and 0.96 for CTR. Conclusions. Our results confirm that also in newborns LUS is at least as accurate as CXR in the diagnosis of PTX while CTR has a lower accuracy.

Peritonitis is an uncommon localization of tuberculosis in Italy; diagnosis and treatment are often difficult and delayed. Fifteen cases, followed by Infectious Diseases Department in Treviso from 2000 to 2010, are described. Mortality and long term complications were absent, in contrast with medical literature. The usefulness of steroid therapy is still uncertain. Other sites of infection were present in 60 percent of patients (pulmonary TB in 47%), urging the clinician to examine the case promptly to determine infectiousness status.

The authors report their experience with 9 patients, affected by pancreatic and periampullary carcinoma, treated using pancreaticoduodenectomy with pyloric preservation. They analyse the physiopathology of this technique, by the light of the international reports, and note the advantages that this technique allows about the nutritional status and the quality of life of the patients operated on.

Advances in laparoscopic surgical procedures will facilitate the solution of specific problems, especially in emergency surgery. A simple technique of intracorporeal finger assistance, which permits a fast and safe solution in selected cases involving right and left lower abdominal quadrants, is described. The forefinger, introduced like a cannula, can be used to complete laparoscopic procedures in which there is potential risk for bowel injury or failure in using laparoscopic instruments.
