Introduction: Synovial sarcoma is one of the most common soft tissue sarcomas in children. Guidelines regarding the adequate extent of resection margins and the role of re-resection are lacking. We sought to evaluate the adequate resection margin and the role of re-resection in predicting outcomes in children with synovial sarcomas., Methods: A cohort of 36 patients less than 18 years of age at diagnosis who were treated for localized synovial sarcoma at three tertiary pediatric hospitals between January 2004 and December 2020 were included in this study. Patient and tumor demographics, treatment information, and margin status after surgical resection were collected from the medical record. Clinical, treatment, and surgical characteristics, as well as outcomes including hazard ratios (HRs), event-free survival (EFS), and overall survival (OS) were compared by resection margins group and re-resection status., Results: Patients in the R1 resection group were significantly more likely to relapse or die compared to patients in the R0 resection group. However, there was no significant difference in EFS (HR 0.52, p = 0.54) or OS (HR 1.56, p = 0.719) in R0 patients with less than 5 mm margins compared to R0 patients with more than 5 mm margins. Patients with R1 on initial or re-resection had significantly worse OS than patients who had R0 resection on initial or re-resection (HR = 10.12, p = 0.005)., Conclusion: This study re-affirms that R0 resection is an independent prognostic predictor of better OS/EFS in pediatric synovial sarcoma. Second, our study extends this finding to report negative margins on initial resection or re-resection is associated with better OS/EFS than positive margins on initial resection or re-resection. Lastly, we found that there is no difference in outcomes associated with re-resection or <5 mm margins for R0 patients, indicating that re-resection and <5 mm margins are acceptable if microscopic disease is removed., (© 2024 The Author(s).

Objective: This article aimed to review the main currently described lines and angles and gather them in a single article and arrange them in a systematic way to facilitate the process of assessment of the pediatric foot for deformities., Methods: The review was a scoping literature review. Electronic database websites such as PubMed, Europe PMC, Cochrane Library, and Google Scholar in addition to some books on anatomy and human movements biomechanics, diagnostic radiology, and orthopedics were searched for relevant articles for the topic of the present review. No statistical analysis was applied in this review., Results: Data from thirty articles included in this review were arranged into different subheadings. In the anteroposterior view (AP), assessment of the hindfoot deviation was by the AP talo-calcaneal angle (Kite's angle); the forefoot and midfoot for abduction and adduction alignment was by the AP talo-first metatarsal angle, the talo-second metatarsal angle, the calcaneo-second metatarsal angle, the calcaneofifth metatarsal angle; the forefoot and midfoot rotation was by observing the normal proximal convergence of the metatarsal bones axes. In the lateral view, assessment of the hindfoot sagittal plane alignment was by the lateral tibio-calcaneal angle; hindfoot varus or valgus deviation by the lateral talo-calcaneal angle; talus bone alignment by talar declination angle and the tibio-talar angle; calcaneal bone alignment by the calcaneal inclination angle and the tibio-calcaneal angle, the midfoot and forefoot sagittal plane alignment for the plantar arch by the lateral talo-first metatarsal -Meary's- angle, the calcaneal inclination angle, and the lateral calcaneofirst metatarsal -Hibbs- angle; forefoot and midfoot rotational alignment by observing the overlap shadows of the metatarsals' shafts and drawing their axes., Conclusion: Drawing certain lines and angles with a systematic approach to assess different regions of the foot in the radiographic films of children can facilitate the process of assessment of the foot (as a whole) for deformities., Competing Interests: The author declares that he has no conflict of interest, (© Association of Resident Doctors, UCH, Ibadan.)

Purpose: The present study aimed to treat fractures of the distal end of the radius in children with Robert Jones (RJ) bandage. The objective was to compare this treatment modality with the cast regarding the frequency of the complication occurrence, child comfortability, and family satisfaction., Methods: The study was a randomized controlled non-inferiority clinical trial including children with recent (less than 5 days) fractures at the distal end of the radius OTA/AO 23-A2, which is usually treated conservatively. Those with open fractures, pathological fracture, severely displaced fracture that needs reduction or multiple injuries were excluded. The participants were divided randomly into 2 groups according to the treatment modalities. Group 1 was treated by plaster of Paris cast (the control group), and Group 2 by modified RJ bandage (the trial group). The difference between the 2 groups was found by the Chi-squared test. The difference was considered statistically significant when the p value was less than 0.05., Results: There were 150 children (aged 2 - 12 years, any gender) included in the study, 75 in each group. The complications occured in 5 (3.3%) cases only, pressure sores of 3 cases in Group 1 and fracture displacement of 2 cases in Group 2. There was no statistically significant difference in the rate of complication occurrence between both modalities of treatment (p = 0.649). Children treated by RJ bandages were more comfortable than those treated by the cast (97.3% vs. 73.3%, p < 0.001) with a statistically significant difference between them. Contrary to that, the families were more satisfied with the cast than RJ bandage (88.0% vs. 81.3%), but without a statistically significant difference (p = 0.257)., Conclusion: RJ bandage is a non-inferior alternative to the cast for the treatment of fractures at the distal end of the radius that can be treated conservatively in children., (Copyright © 2023 Chinese Medical Association.

Background: The purpose of the current study was to upgrade the International Hip Dysplasia Institute (IHDI) classification of developmental dysplasia of the hip (DDH)., Methods: The upgrading was suggested by adding the state of the acetabulum (type A for the normal acetabulum and type B for the dysplastic one). The pelvic radiographic films of 110 children suspected to have DDH were used by three observers to sort out the hips into grades according to the original form and the suggested upgraded one subsequently., Results: The interobserver reliability between the observers improved from a good level (intraclass correlation coefficient [ICC], 0.885; 95% confidence interval [CI], 0.856-0.909) with the original form to an excellent level (ICC, 0.919; 95% CI, 0.898-0.936) with the upgraded form. When the upgraded form was used, only the grade 1 hips were divided into types A and B, while those classified as grades 2, 3, and 4 were all graded as type B only., Conclusions: The IHDI classification of DDH can be upgraded into grade 1A, grade 1B, grade 2, grade 3, and grade 4., Competing Interests: CONFLICT OF INTEREST: No potential conflict of interest relevant to this article was reported., (Copyright © 2022 by The Korean Orthopaedic Association.)

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital disorder of the Müllerian ducts in which there is uterus didelphys, obstructed hemivagina and unilateral renal agenesis. The most common presentation is an abdominal mass secondary to hematocolpos, pain and dysmenorrhea. However, in some cases, such as the one we present here, menses are normal due to an obstructed hemivagina, and diagnosis can be delayed. We describe evaluation and surgical management of a 13-year-old girl with this condition who was diagnosed by computed tomography (CT) scan and confirmed by pelvic ultrasound and surgical exploration, as well as a review of the literature.

Objective: Surgical wound infections remain a significant source of postoperative morbidity. This study was undertaken to determine prospectively the incidence of postoperative wound infections in children in a multi-institutional fashion and to identify the risk factors associated with the development of a wound infection in this population., Summary Background Data: Despite a large body of literature in adults, there have been only two reports from North America concerning postoperative wound infections in children., Methods: All infants and children undergoing operation on the pediatric surgical services of three institutions during a 17-month period were prospectively followed for 30 days after surgery for the development of a wound infection., Results: A total of 846 of 1021 patients were followed for 30 days. The overall incidence of wound infection was 4.4%. Factors found to be significantly associated with a postoperative wound infection were the amount of contamination at operation (p = 0.006) and the duration of the operation (p = 0.03). Comparing children who developed a wound infection with those who did not, there were no significant differences in age, sex, American Society of Anesthesiologists (ASA) preoperative assessment score, length of preoperative hospitalization, location of operation (intensive care unit vs. operating room), presence of a coexisting disease or remote infection, or the use of perioperative antibiotics., Conclusions: Our results suggest that wound infections in children are related more to the factors at operation than to the overall physiologic status. Procedures can be performed in the intensive care unit without any increase in the incidence of wound infection.
