RESUMEN
BACKGROUND: In this study, two fibrin sealant products, Fibrin Sealant Grifols (FS Grifols 80 mg/mL fibrinogen; 500 IU/mL thrombin) and Evicel (fibrinogen 55-85 mg/mL; thrombin 800-1200 IU/mL) were studied for efficacy in achieving hemostasis at a targeted bleeding site (TBS) on parenchymous or soft tissue in pediatric surgeries. METHODS: This phase 3, single-blind, active comparator, non-inferiority trial compared the number of patients achieving hemostasis at a TBS at four (T4 - primary endpoint), seven (T7) and 10 (T10) minutes after application, Safety and tolerability were assessed by recording adverse events during and after procedures. Eligible patients were <18 years old undergoing elective, open, non-cardiac thoracic, abdominal or pelvic surgeries. Preterm (<37 weeks gestation) and newborn (0-27 days) infants were eligible. RESULTS: At T4, 98.7% of FS Grifols group (n = 91) and 95.4% of the Evicel group (n = 87) achieved hemostasis. All patients with residual bleeding at T4 were undergoing soft tissue surgery. All patients achieved hemostasis by T7. At T10, all patients achieved hemostasis except one (FS Grifols (no observation recorded)). There were no incidents of persistent bleeding. For FS Grifols, 26.5% of patients had treatment-emergent adverse events (TEAEs) and 18.4% for Evicel. One TEAE (moderate procedural pain - FS Grifols group) was considered possibly related to study treatment. Three patients died for reasons unrelated to the study medications. CONCLUSIONS: FS Grifols was safe and effective at achieving hemostasis in pediatric patients having parenchymous or soft tissue surgeries. The efficacy of FS Grifols was non-inferior to Evicel. LEVEL OF EVIDENCE: I.

BACKGROUND Computer-aided design (CAD) has been used in the Nuss procedure to determine the bar length and shape. Despite computer aid, the shape and design remain quite intuitive. We tested a new algorithm to determine the optimal bar shape. MATERIAL AND METHODS The normal sterno-vertebral distance was defined on computed tomography (CT) scans of patients without pectus excavatum (PEx) at the same level where the deepest depression was found on CT scans of 97 patients with PEx. Four points were marked on the CT scan of 60 patients with PEx at the deepest deformity: P1: edge of the vertebra; P2: edge of the deformity; P3: the expected contact point of the bar and the rib; and P4: the expected end of the bar. The algorithm generated 3 circles upon these points, and the fusion of the arcs drew the line of the ideal bar. Corrected and normal sterno-vertebral distance values were compared with the Mann-Whitney U test. Ten bars were bent manually guided by a 1: 1 printout of the designed bar and were implanted in 10 adolescents. RESULTS The shortest sterno-vertebral distance was 3 cm below the intermammillary line in PEx patients. The normal mean sterno-vertebral distance at this level was 10.16±1.35 cm in non-PEx patients. The mean virtually corrected sterno-vertebral distance was 10.28±1.27 cm. No significant difference was found (P=0.44). The bars were seamless and were successfully implanted. No bar needed adjustment, the operation time was shorter, and the patient satisfaction score was 9.4/10. CONCLUSIONS With our new algorithm, an optimal Nuss bar can be designed.

INTRODUCTION: The COVID-19 pandemic influenced not only the elective, but the acute surgeries also, all around the world. Some authors found more delayed cases and more orchiectomies performed in childhood because of testicular torsions during the pandemic. OBJECTIVE: To examine the impact of the COVID-19 pandemic on the treatment of childhood testicular torsion and the frequency of semicastration due to torsion at the first author's institute. METHODS: A retrospective observational cohort study was performed in a representative Hungarian centre. Boys under 18 years of age operated with testicular torsion were divided into two groups: before COVID-19 (BC; 01/07/2017-31/12/2019) and during COVID-19 (DC; 01/01/2020-30/06/2022) pandemic. PARAMETERS: elapsed time between the first symptom and arrival at the hospital (<24 h or >24 h), elapsed time to start the surgical procedure since the arrival to the hospital and the rate of semicastration were analysed. For statistical analysis, Mann-Whitney U and chi2 tests were used. RESULTS: During the study period, altogether, 100 patients (45 BC and 55 DC) were operated on testicular torsion. Statistically significant difference was found between the two timeframes: in the elapsed time from the first symptom and arrival at the hospital (p = 0.048). During the pandemic surgeries started earlier (1.5; 2.5 h) than before the pandemic (1.5; 3.25 h, p = 0.01). No difference was found in the frequency of semicastration between the groups (p = 0.594). DISCUSSION: Contrary to the literature, during the COVID-19 pandemic, patients with testicular torsion arrived earlier at the hospital, and surgeries were started earlier, than before the pandemic at the investigated institute. CONCLUSION: The reason behind this accelerated care pathway might be the absence of less severe cases during the COVID-19 period. When people are more prone to stay home, if it does not seem necessary to seek help for any kind of non-urgent medical problem. Orv Hetil. 2023; 164(35): 1367-1372.

BACKGROUND: Staged laparoscopic traction orchiopexy (SLTO) is a novel technique for the intra-abdominal testis (IAT) based on elongation of the testicular vessels without separating them. This multicenter study evaluated the medium-term results of this technique. METHODS: Data of SLTO performed in three pediatric surgical centers between 2013 and 2020 were analyzed retrospectively. In 2021, physical and Doppler ultrasound examinations were performed to determine the position and viability of testes. Success was defined as an intra-scrotal testicle without atrophy. RESULTS: SLTO was performed on 48 cases (55 testes, 7 bilateral). Mean age at first stage was 2.9 (0.8-12.6) years. High intra-abdominal testes were found in 16.4% and in 60% morphological abnormalities were observed. To fix the testes to the abdominal wall monofilament suture was used in 67.3%, braided in 29.1%. Mean time between the two stages was 16.4 weeks; three testes required redo traction. Perioperative complications occurred in 21 patients (38.2%) including insufficient fixation (11), testicular atrophy (4), wound complications (4), adhesion of the spermatic cords (1) and hydrocele (1). In case of insufficient fixation monofilament sutures were used in 90.9%. In 2021 38 patients (43 testes) had physical and 36 patients (41 testes) had ultrasound examinations. Mean follow-up was 2.7 (0.34-7.9) years. Altogether five atrophies were identified, and three testicular ascents (7.0%) occurred. The overall success rate was 82.2%. CONCLUSIONS: SLTO may be a feasible alternative to conventional treatments of IATs. Additionally, braided suture seems to be a better option to fix the testicle to the abdominal wall. LEVEL OF EVIDENCE: LEVEL IV.

INTRODUCTION: The most common surgical intervention in childhood is inguinal hernioplasty. OBJECTIVE: The aim of the authors was to evaluate the learning curve of PIRS (percutaneous internal ring suturing). METHOD: A prospective observational cohort was studied including patients under the age of 18 years with planned PIRS between 2018 and 2019. Patients with urgent intervention (incarceration) or other surgical procedures performed simultaneously were excluded. The incidence of metachronous hernia, surgical time, number of conversions and complications were analyzed. The postoperative follow-up time was 1-4 weeks. A phone call check-up was performed in 2022. RESULTS: PIRS was performed in 126 patients (57 boys, 69 girls) with an average age of 4.6 years. The average surgical time was 26.5 min, in the case of experts it was reduced to 22.9 min. The surgeries were longer in boys than in girls (30.5 vs. 23 min). Unilateral surgeries were faster than bilateral ones (23.7 vs. 33.6 min). Initially, girls were operated with PIRS, the surgical time decreased. When trainees started to learn the procedure, the surgical time increased, then decreased again. The same trend was observed in boys. 28 metachronous hernias were found. 3 conversions and 3 intraoperative complications were observed. During the postoperative follow-up, 1 recurrence, 4 postoperative complications were observed. The phone call check-up with 92/126 patients revealed 1 more recurrence and 6 chronic complaints. DISCUSSION: PIRS is a good laparoscopic "teaching" procedure during the training, but the open procedure has still place in the treatment. CONCLUSION: PIRS is a safe procedure in childhood and can be easily learned. It is an excellent method in basic laparoscopic training by use of which metachronous hernia can be recognized.

BACKGROUND: There are several options available for conservative treatment of partial-thickness burns, however, reliable, affordable, and easily obtainable animal testing models are hard to find for the comparison of the different treatment methods. We aimed at developing a preclinical testing model and at comparing four treatment methods for superficial partial-thickness burns. METHODS: Burn injury was induced in 90 adult male Wistar rats by placing the 130°C hot tip of a commercially obtainable soldering device for 30 s on the clipped skin of the interscapular region at a steady pressure. Skin histology was studied on days 5, 10, and 22 after the induction of the burn injury, on which days, respectively, the ratio of the not epithelialized wound (%), the extent of re-epithelialization (score), and the scar thickness (µm) were assessed. We compared 4 groups: silver-sulfadiazine cream, zinc-hyaluronan gel, silver foam dressing, and the combination of zinc-hyaluronan gel with a silver foam dressing. RESULTS: On day 5, the induction of superficial partial-thickness burn injury was confirmed histologically in the rats. The zinc-hyaluronan gel and the combination treatment resulted in a markedly smaller ratio of the non-epithelialized area (29 ± 10% and 28 ± 13%, respectively) than silver-sulfadiazine cream (69 ± 4%; p < 0.01). On day 10, the extent of re-epithelialization was the lowest (â¼0.2) in the silver-sulfadiazine cream group, while the other 3 treatments performed significantly better. The combination treatment lead to the maximal score of 2 in all rats, which was higher than in the other 3 treatment groups. On day 22, the scar thickness was the smallest in the combination treatment group (560 ± 42 µm), which was significantly less than in the silver-sulfadiazine cream group (712 ± 38 µm; p < 0.05). CONCLUSIONS: We designed and histologically confirmed a reproducible method for induction of superficial partial-thickness burns in rats for preclinical testing. In our model, the combination of zinc-hyaluronan gel with silver foam dressing was more effective than either of its components alone or than silver-sulfadiazine cream.

Introduction: The public health threat of substandard and falsified medicines has been well known in the last two decades, and several studies focusing on the identification of products affected and preventing consumption have been published. However, the number of these products reaching patients and causing health consequences and adverse drug reactions is not a well-researched area. Objectives: Our aim was to identify and describe the characteristics of cases that are related to adverse drug reactions potentially originating from counterfeit medication using publicly available pharmacovigilance data. Methods: A descriptive study was performed based on pharmacovigilance data retrieved from Individual Case Safety Reports (ICSRs) identified in the European Medicines Agency's EudraVigilance and FDA Adverse Event Reporting System (FAERS) databases in April 2022 using selected MedDRA preferred terms: counterfeit product administered, product counterfeit, product label counterfeit, product packaging counterfeit, suspected counterfeit product, adulterated product, product tampering, and suspected product tampering. ICSRs were analyzed by age and gender, by year of reporting, region of origin, reporter's profession, and severity of the outcome. The disproportionality method was used to calculate pharmacovigilance signal measures. Results: A total of 5,253 cases in the FAERS and 1,049 cases in the EudraVigilance database were identified, generally affecting middle-aged men with a mean age of 51.055 (±19.62) in the FAERS and 64.18% of the cases between 18 and 65 years, while the male to female ratios were 1.18 and 1.5. In the FAERS database, we identified 138 signals with 95% confidence interval including sildenafil (n = 314; PRR, 12.99; ROR, 13.04; RRR, 11.97), tadalafil (n = 200; PRR, 11.51; ROR, 11.55; RRR, 10.94), and oxycodone (n = 190; PRR, 2.47; ROR, 2.14; RRR, 2.47). While in the EV data 31, led by vardenafil (n = 16, PRR = 167.19; 101.71-274.84; 95% CI, RRR = 164.66; 100.17-270.66; 95% CI, ROR = 169.47; 103.09-278.60; 95% CI, p < 0.001), entecavir (n = 46, PRR = 161.26, RRR = 154.24, ROR = 163.32, p < 0.001), and tenofovir (n = 20, PRR = 142.10, RRR = 139.42, ROR = 143.74, p < 0.001). Conclusion: The application of pharmacovigilance datasets to identify potential counterfeit medicine ADRs can be a valuable tool in recognition of potential risk groups of consumers and the affected active pharmaceutical ingredients and products. However, the further development and standardization of ADR reporting, pharmacovigilance database analysis, and prospective and real-time collection of potential patients with health consequences are warranted in the future.
RESUMEN
Introduction: The advantages of laparoscopic against open appendectomy were observed both in adults and children. Objective: The aim of the authors was to study the learning period when they switched from open to laparoscopic appendectomy. Methods: Retrospective, observational study was performed. Children (018 years) between 2016 and 2017 were included, who underwent acute appendectomy. Exclusion criteria were other surgical procedure performed at the same time (Meckel's diverticulum, ovarian pathology), converted laparoscopic procedure and malignancies. Patients were divided to open appendectomy (OA) and laparoscopic appendectomy (LA) groups. Duration of the procedures, length of hospital stay, postoperative complications were reviewed. For statistical analysis MannWhitney, Fisher's exact and chi2 tests were used. Results: During the study period, 297 appendectomies were performed (open: 149, laparoscopic: 148). In 2017, reaching the end of the learning curve, laparoscopy was the faster procedure (p = 0.0003). The length of stay was shorter in laparoscopic than in open appendectomy (p<0.0001). There was no difference in the number of postoperative complications between the OA and the LA groups (p = 0.2409). Discussion: Our study supports the international studies in English literature which showed that the results of a laparoscopic operation in childhood after the "learning phase" do not differ, and may be better, than those of an open one. Conclusion: LA is a safe and fast procedure in childhood. Even paediatric surgeons who did previously only open procedures, can switch to the laparoscopic technique following a short learning curve.

BACKGROUND: Laboratory skills training is an essential step before conducting minimally invasive surgery in clinical practice. Our main aim was to develop an animal model for training in clinically highly challenging laparoscopic duodenal atresia repair that could be useful in establishing a minimum number of repetitions to indicate safe performance of similar interventions on humans. MATERIALS AND METHODS: A rabbit model of laparoscopic duodenum atresia surgery involving a diamond-shaped duodeno-duodenostomy was designed. This approach was tested in two groups of surgeons: in a beginner group without any previous clinical laparoscopic experience (but having undergone previous standardized dry-lab training, n = 8) and in an advanced group comprising pediatric surgery fellows with previous clinical experience of laparoscopy (n = 7). Each participant performed eight interventions. Surgical time, expert assessment using the Global Operative Assessment of Laparoscopic Skills (GOALS) score, anastomosis quality (leakage) and results from participant feedback questionnaires were analyzed. RESULTS: Participants in both groups successfully completed all eight surgeries. The surgical time gradually improved in both groups, but it was typically shorter in the advanced group than in the beginner group. The leakage rate was significantly lower in the advanced group in the first two interventions, and it reached its optimal level after five operations in both groups. The GOALS and participant feedback scores showed gradual increases, evident even after the fifth surgery. CONCLUSIONS: Our data confirm the feasibility of this advanced pediatric laparoscopic model. Surgical time, anastomosis quality, GOALS score and self-assessment parameters adequately quantify technical improvement among the participants. Anastomosis quality reaches its optimal value after the fifth operation even in novice, but uniformly trained surgeons. A minimum number of wet-lab operations can be determined before surgery can be safely conducted in a clinical setting, where the development of further non-technical skills is also required.

Globally there is abundant terrestrial surface gravity data used to study the time variation of gravity related to subsurface mass and density changes in different geological, geodynamical and geotechnical environments. We present here a tool for analysing existing and newly acquired, 4D gravity data, which creates new findings from its reuse. Our method calculates in an almost automatic way the possible sources of density change responsible for the observed gravity variations. The specifics of the new methodology are: use of a low number of observation points, relatively small source structures, low signal/noise ratio in the data, and a free 3D source geometry without initial hypothesis. The process is based on the non-linear adjustment of structures defined by aggregation of small cells corresponding to a 3D section of the sub-floor volume. This methodology is implemented in a software tool, named GROWTH-dg, which can be freely downloaded for immediate use, together with a user manual and application examples.
RESUMEN
OBJECTIVES, SETTING AND PARTICIPANTS: In July 2011, the EU adopted the Falsified Medicines Directive (FMD) primarily aiming to prevent the infiltration of falsified medicines into the legitimate supply chain. Our aim was to measure the cost elements of FMD implementation and operation using an internationally adaptable tool among Hungarian hospital pharmacies. DESIGN: A 41-item questionnaire was developed to evaluate the implementation process and associated cost consequences leading up to February 2019, and the stabilisation period. RESULTS: Our representative data are supported by the high response rate, as 44.8% of the Hungarian hospital pharmacies have completed the survey. Human resource requirements related to decommissioning activities were measured as working hours and were expressed in full time equivalent (FTE). We have found an increased workload with extra 0.25 pharmacist and 0.75 technician FTE/institution at the end of the stabilisation period. The entire infrastructural and IT implementation costs were determined as 2173, on average (SD: 3366) and the median was 1506 (range: 0-20 723). The total IT investment cost per institution was valued at 1410 (SD: 335). We identified a positive correlation (R=0.663) in consideration of the costs, the number of beds and the number of hospital locations with a multivariate linear regression model. At the time of our survey, 76.7% of the respondents experienced drug shortages, 58.1% reported suspected increase in drug costs regarding serialised medications, and 53.5% noticed an increase in packaging size. CONCLUSIONS: Notably, our research is the first complex study depicting FMD cost implications in the hospital pharmacy sector in Central Europe, indicating decommissioning significantly impacted workflow referencing human resources and IT.

We report on an 11-year-old girl with cystic fibrosis who presented with thoracic pain and an extensive subcutaneous emphysema and subsequently developed progressive respiratory distress. The chest computed tomography revealed a huge pneumomediastinum. Due to the development of severe respiratory failure, urgent needle thoracocentesis was necessary that resulted in only temporary improvement. Therefore, under general anesthesia two mediastinal drains were introduced. Using active suction, the size of the pneumomediastinum decreased gradually and the drains were removed after 3 weeks. Here, we describe an extremely rare situation, when acute surgical intervention was necessary in a child with spontaneous pneumomediastinum.
RESUMEN
BACKGROUND: Appendicitis is one of the most common diagnoses in pediatric populations. Although new recommendations for the treatment of pediatric appendicitis were published, management varies among different institutions. OBJECTIVES: To determine current practices in 4 (n = 4) representative pediatric surgical departments in Central Europe. MATERIAL AND METHODS: One department from each of the 4 countries was surveyed using an online questionnaire. Questions focused on preoperative, operative and postoperative practices in 2018, particularly those related to antibiotic (ATB) therapy and laparoscopy. RESULTS: A total of 519 appendectomies were performed, among which 413 (79.6%) were laparoscopic appendectomies (LAs), with a conversion rate of 5.1%. Appendectomy, as an elective procedure, was performed in 43 (8.3%) patients. One-quarter (129 patients) had complex appendicitis and 72.3% of these were operated laparoscopically. In 3 departments, ATB prophylaxis was administered, based on the decisions of the operating surgeon. One department used standard ATB prophylaxis (metronidazole). Whenever phlegmonous appendicitis was detected, ATB were administered therapeutically in 2 departments. Two other departments administered ATB based on surgeon decision. The choice of ATB was not standardized. If complex appendicitis was detected, all sites administered ATB therapeutically. The type of ATB treatment was standardized in complex cases in 2 departments. Thirty-four complications (6.6%) at surgical sites were recorded - 4.1% (16/390) after uncomplicated and 14% (18/129) after complex appendicitis. Thirty-two occurred after acute surgeries and 26 of these followed laparoscopic procedures. Postoperatively, intra-abdominal abscesses occurred in 3.5% of laparoscopic and in 2.9% of open appendectomy (OA) cases. CONCLUSIONS: This questionnaire study showed that treatment outcomes for appendicitis in children in Central Europe are comparable with data reported in the literature. Laparoscopic appendectomy is the predominant surgical method, but there is a little consensus for ATB treatment in the management of appendicitis at our 4 pediatric surgical departments.

Urothelial neoplasms of the bladder (UNB) are considerably rare throughout the pediatric population. UNB develops from the urothelial tissue in the form of a benign disease, generally favoring a successful prognosis in the majority of cases. The authors present the diagnosis and treatment regarding two medical case reports in which urothelial papilloma was diagnosed and effectively treated. Case 1 : A 15-year-old male patient was presented to our clinic complaining of a painless yet distinctive, macroscopic form of hematuria. Following a routine examination, which included ultrasound (US) and intravenous pyelography, the urethrocystoscopy revealed an intravesical solitary lesion positioned in the vicinity of the left ureteral orifice. Additionally, histology confirmed urothelial papilloma. During the follow-up, laboratory, urinary control tests, and US results all proved negative. Case 2 : A 13-year-old male patient was admitted to our clinic and examined, in regard to complaints associated with recurrent abdominal pain. The pathology was discovered incidentally on abdominal US. Preoperative US and magnetic resonance imaging (MRI) studies ensued, resulting in a scheduled MRI, followed by urethrocystoscopy, which confirmed an intravesical solitary lesion positioned near the right ureteral orifice. Histology revealed urothelial papilloma. During the follow-up control cystoscopy, one resection was repeated due to the presence of a residual tumor. Today, 10 years since the presence of uroepithelial papilloma, both patients are asymptomatic and tumor-free. If there is likely suspicion of recurrence, cystoscopy is recommended.
RESUMEN
Unstable distal metaphyseal and dia-metaphyseal fractures of the radius may have treated with a variety of operative techniques, Kirschner wires (K-wires), dorsally inserted titanium elastic stable intramedullary nailing (DESIN), and short titanium elastic stable intramedullary nailing (SESIN) in children.The aim of this study was to evaluate the differences in clinical and radiographic outcomes between these methods.Between January 2009 and December 2017 196 children were treated for forearm fractures in the distal third of the distal radius. Gender of the patients, different types of surgical techniques, number of postoperative X-rays, date of metal removal and degree of axis deviation after the metal removal were studied. Distance of the fracture line from the radiocarpal surface, the width of the distal epiphysis of the radius, and the cumulative width of the distal epiphysis of the ulna and radius were analyzed.Out of the 196 children, stabilization of the fracture was achieved by K-wire in 139, by DESIN in 44, and by SESIN in 13 patients. The average time of metal removal was significantly shorter (3.8 months), following stabilization with K-wire. In children treated with K-wire, axial deviation of <5° was seen in 118 patients, 5° to 10° deviation in 15 patients, while deviation was above 10° in 6 children. In the DESIN group, <5° axial deviation was found in 37 patients and 5° to 10° in seven patients. In all 13 children treated with SESIN, axial deviation was measured to be <5°. The fracture distance from the radiocarpal surface was on average 23.7 and 45.6âmm in the children treated with K-wire and DESIN, respectively.Fracture distance from the radiocarpal surface might determine the type of surgical technique required. If the distance of the fracture line is less than the width of the distal radius, osteosynthesis with a K-wire is recommended, while if the distance of the fracture is more than the cumulative width of the radius and the ulna, then DESIN may provide better results. The use of SESIN may be indicated when the area of the growth plate is injured.

INTRODUCTION: The potential of malignant transformation and its risk factors after bladder augmentation performed in childhood are still unknown. The necessity of surveillance cystoscopies and biopsies has been questioned in the past decade. OBJECTIVE: In a previous study, the authors did not detect any malignancy after colocystoplasty (CCP) or gastrocystoplasty (GCP) during the short-term follow-up, however, various alterations of the mucosa were found. A correlation between the nature of histological changes and the frequency of bacterial colonization after CCP were also found. The authors hypothesized that a longer-term follow-up of their patients would reveal an increase in pathological change or show stronger association between the histological alteration, bacterial colonization, and/or stone formation. PATIENTS AND METHODS: Thirty-five patients (20 cases of colocystoplasties - CCPs; 15 cases of gastrocystoplasties - GCPs) participated in the study published in 2002. All patients were followed biannually with endoscopic assessment and biopsies. Two independent pathologists, evaluated regular biopsies from the native bladder, from the segment used for augmentation and from the anastomosis line. Etiology, frequency of positive urine cultures, and stone events were recorded and compared with histological findings between groups and with the previously published results. RESULTS: Continuous surveillance allowed the follow-up of 30 patients (CCP 19/20, GCP 11/15) for 20 and 15 years. No malignancies were identified. Results of biopsies showed significant difference between groups (summarized in the tables). Chronic inflammatory changes were found following both types of augmentations, but they were more common in the urothelium following GCP and more common in the colonic mucosa following CCP. The rate of metaplastic lesions was higher after gastrocystoplasty (GCP). Significant association was found between the etiologic factor and the nature of histological change after CCP, as metaplastic lesions occurred only in patients with bladder exstrophy. Stones occurred more frequently in exstrophy patients as well. The nature of the histological changes did not correlate with positive urine cultures in either of the groups. Significantly higher incidence of bacterial colonization and stone occurrence were found after CCP. CONCLUSIONS: Long-term follow-up of the patients failed to reveal an increase in pathological changes, and no malignancies were observed. According to the results of this study, etiology of bladder dysfunction and the type of augmentation might influence the histological alterations after augmentation cystoplasty. The efficiency of surveillance cystoscopies and biopsies are low. The present data suggest that surveillance cystoscopy and biopsy should not be routinely performed, and should be done only if the symptoms are suspicious for malignancy.

In pediatric burns the use of systemic antibiotic prophylaxis is a standard procedure in some burn centers, though its beneficial effect on the infectious complications is debated. The present meta-analysis aimed at determining whether systemic antibiotic prophylaxis prevents infectious complications in pediatric patients with burn injuries. We searched the PubMed, EMBASE, and Cochrane Library databases from inception to August 2019. We included 6 studies, in which event rates of infectious complications were reported in children with burn injuries receiving or not receiving systemic antibiotic prophylaxis. We found that the overall odds ratio (OR) of developing an infection (including local and systemic) was not different between the groups (OR = 1.35; 95% CI, 0.44, 4.18). The chances for systemic infectious complications alone were also not different between antibiotic-treated and non-treated patients (OR = 0.74; 95% CI, 0.38, 1.45). Based on the age, affected total body surface area, and country income level, we did not find any subgroup that benefited from the prophylaxis. Our findings provide quantitative evidence for the inefficacy of systemic antibiotic prophylaxis in preventing infections in pediatric burns. To validate our conclusion, multinational, randomized trials in a diverse population of children with burn injuries are warranted.

A full-term male neonate presented with a left sided cervical lump at the level of the thyroid gland. Magnetic resonance imaging (MRI) showed a benign heterogeneous solid mass with lobulated margins. The tumor underwent complete excision. Histology revealed the diagnosis of chondromesenchymal hamartoma in ectopic thyroid tissue.
