Antibiotic therapy in pediatric acute appendicitis: Compliance with local protocol to reduce antibiotic overuse.

PURPOSE: Acute appendicitis is one of the commonest surgical emergencies in pediatrics. Treatment usually consists of a combination of surgery and antibiotics. The present study was designed to assess compliance with our local antibiotic protocol and analyse the consequences of non-compliance. METHODS: Children presenting with acute appendicitis between 2015 and 2017 were included in this study. The diagnosis of acute appendicitis was confirmed during surgery. Data concerning the antibiotic therapy received and infectious complications were reviewed. RESULTS: A total of 142 children with acute appendicitis were included. Antibiotic therapy complied with the protocol in 27.4% of cases, while an excessive duration of antibiotic therapy was observed in 65% of cases. A total of 270 days of non-recommended antibiotic therapy was noted; 32% of patients received a non-recommended combination of antibiotics. The infectious complications rate was 12.8% in the group of patients receiving appropriate antibiotic therapy, and 11.6% in the group with non-compliance to the protocol. No statistically significant difference between the groups was found (P=0.85). CONCLUSION: Poor compliance with the antibiotic guidelines for appendicitis resulted in antibiotic overuse with no benefit in terms of anti-infective efficacy. Better information for the medical team and repeated evaluation of our practices are essential.

Transient pseudohypoaldosteronism: a potentially severe condition affecting infants with urinary tract malformation.

BACKGROUND: Secondary pseudohypoaldosteronism (S-PHA) is a life-threatening condition affecting young children with urinary tract malformation (UTM). OBJECTIVE: The aim of the study was to highlight the diagnosis of S-PHA in children with UTM and propose appropriate management. STUDY DESIGN: The authors retrospectively reviewed cases of S-PHA related to UTM observed at the institution and searched the PubMed® database to review the literature. RESULTS: A total of 116 cases of S-PHA associated with UTM, including the four cases from the institution, were reviewed. One hundred six cases (92.2%) were younger than 6 months, and 95 cases (81.9%) occurred in boys. Urinary tract infection was associated in 105 cases (90.5%). All types of UTM were observed. In the absence of urinary tract infection, S-PHA was related to bilateral UTM or solitary kidney. In 89 cases (76.5%), S-PHA resolved with medical treatment only. In cases of UTM requiring immediate surgery, electrolyte imbalance related to S-PHA also resolved after surgery. Children with associated urinary tract infection and bilateral UTM are at higher risk of developing S-PHA. DISCUSSION: The pathogenesis of S-PHA has not been fully elucidated. Renal tubular immaturity may be one of the factors involved, in view of the young age of the population being affected. A high rate of bilateral UTM (or UTM on solitary kidney) was observed (50.9%), suggesting an association with S-PHA. In the absence of urinary tract infection (UTI), S-PHA appeared to occur more frequently in the presence of bilateral UTM. Although the indication for early surgery remains unclear, it may have a role in the prevention of UTI and prevention of recurrence of S-PHA. Serum electrolytes should be checked in children with UTM before urological surgery, and/or presenting urinary tract infection, before the age of 6 months. The results of this study must be interpreted cautiously because of its retrospective nature and the fact that data were derived from various articles. Few articles on S-PHA related to UTM have been published in the literature. To the best of the authors' knowledge, the study constitutes the largest series published to date. CONCLUSIONS: S-PHA results in potentially severe electrolyte imbalance and affects children younger than 6 months with UTI and/or UTM. Electrolyte abnormalities related to S-PHA often resolve after administration of appropriate intravenous electrolyte solution and treatment of UTI and/or surgery.

A congenital mesenteric band is a rare cause of intestinal obstruction. We describe a case of upper gastrointestinal obstruction on a jejunal congenital band in a 2-year-old child. The challenge is to make the diagnosis in a patient with no history of previous surgery.

[Complete resolution of inflammatory myofibroblastic tumor of the bladder after antibiotic therapy]. / Régression complète d'une tumeur myofibroblastique inflammatoire de vessie après antibiothérapie.

Inflammatory myofibroblastic tumors (IMT) are rare benign tumors, most commonly arising in the lungs and urinary bladder. Many etiologic factors are suspected in their development, but none have been formally demonstrated. Conventional treatment for bladder IMT is complete surgical resection by partial cystectomy or transurethral resection. We report the case of an 8-year-old girl with documented bladder IMT that resolved completely after antibiotic therapy.
