Perianal abscess in children: an evaluation of microbiological etiology and the effectiveness of antibiotics.

PURPOSE: We aimed to evaluate the demographic characteristics of children with perianal abscess, distribution of microbiological etiology, antibiotic susceptibility, and identify the effectiveness and coverage of antibiotics due to culture results. METHODS: A retrospective study was designed to evaluate pediatric patients with perianal abscesses between January 2013 and December 2022. RESULTS: A total of 197 episodes in 135 patients were evaluated. The median age of the patients was 10 months (22 days-17 years). The isolated microorganisms were Gram-positive bacteria in 56 (28.4%) patients and Gram-negative bacteria in 141 (71.6%) patients. The most common isolated species was Escherichia coli (n = 70, 35.5%), followed by Klebsiella spp. (n = 48, 24.4%), Staphylococcus aureus (n = 37, 18.9%), and Enterobacter spp. (n = 9, 4.5%). Forthy-two percent (n = 58) of isolates were positive for extended-spectrum beta-lactamase, 8% (n = 11) were carbapenem-resistant in Gram-negative bacteria, and 37.5% (n = 21) were methicillin-resistant, 7.1% (n = 4) were vancomycin-resistant in Gram-positive bacteria. According to bacterial culture results, ertapenem plus glycopeptide had the highest antimicrobial coverage rate (92.3%), followed by ertapenem plus clindamycin (89.8%), ertapenem (81.7%), third-generation cephalosporin plus glycopeptide (82.2%), third-generation cephalosporin plus clindamycin (69.5%). CONCLUSION: Ertapenem can be a good choice in the empirical treatment of perianal abscesses in children due to its high coverage rate.

Early endoscopic injection may prevent new scarring in idiopathic detrusor overactivity disorder with vesicoureteral reflux in children.

OBJECTIVE: To present baseline characteristics and the long-term treatment results of three groups of patients with idiopathic detrusor overactivity (IDOD) and vesicoureteral reflux (VUR) according to different treatment regimens, which underwent endoscopic subureteric injection (STING) in the early phase of targeted treatment (TT) (ES group), underwent STING in the late phase of TT (LS group) and with TT only (TT group). PATIENTS AND METHODS: A total of 49 IDOD cases with VUR which were divided into three groups according to treatment regimens were evaluated in terms of age, symptoms, bladder capacities, involuntary contraction pressures (ICP), presence and degree of renal scar, differential renal functions (DF), new scar formation and STING success. RESULTS: There was no significant difference between the groups in terms of age, side, symptoms, presence of urinary tract infection (UTI), DF, ICP and bladder capacity at diagnosis. A high grade of reflux was found to be significantly lower in the TT group (p = 0.037). There was no significant difference in terms of ICP, DF, bladder capacity and reflux grade between ES and LS Group. But new scar formation was more in LS Group (p = 0.003). CONCLUSION: The STING success is satisfactory in IDOD cases with VUR, waiting a long period of time for diminishing symptoms may cost new scar formation.

Can deciphering the growth of Meckel's diverticulum help us to decide the resection technique?

Introduction: The employment of laparoscopic surgical techniques has reignited the debate on managing Meckel's Diverticulum (MD) due to its low complication rates. Nevertheless, concerns have been raised regarding completely removing any potential heterotopic mucosa. Our study aimed to compare surgical approaches in MD and assess the effectiveness of simple diverticulectomy. Methods: Between 2003 and 2022, 139 patients with MD were retrospectively analysed. The study examined the morphometric measurements of the diverticulum and the location of the heterotopic mucosa in the diverticulum regarding growth and symptoms. Results: Simple diverticulectomy achieved the lowest postoperative complication rate among excision techniques (p = 0.03). MD's length, diameter, and distance to the ileocecal valve increase linearly with growth in the first three years of life (p = 0.00, p = 0.01, p = 0.00) but not in subsequent years (p = 0.81, p = 0.43, p = 0.21). As the length of the MD increases, the heterotopic mucosa (HM) is displaced distally (p = 0.01). Patients in whom HM reaches the base of the diverticulum always present with bleeding (p = 0.02). Discussion: Simple diverticulectomy is a safe technique for Meckel's diverticulum resection. Meckel's diverticulum continues to grow until the age of 3. With this growth, the heterotopic mucosa is displaced distally and moves away from the base of the diverticulum. Bleeding is the main symptom in patients with HM reaching the base of the diverticulum. In patients with bleeding or younger than three years of age, simple diverticulectomy may not be considered safe.Level of Evidence: III.
