Child traumatic physical abuse rates and comparisons during the COVID-19 pandemic: Retrospective paediatric single institution review in Texas.

AIM: The COVID-19 pandemic drastically altered human behaviour and socialisation and may have created an environment that could lead to increased incidence of domestic abuse and non-accidental trauma, or child physical abuse (CPA). Initial reports about the effect of the COVID-19 pandemic on the rates of CPA have been mixed. The purpose of this study is to describe the effects of COVID-19 on rates of CPA in a large metropolitan paediatric hospital and level I paediatric trauma centre. METHODS: We identified and compared all CPA admissions under 18 years from May 2019 to February 2020 and considered that to be the pre-COVID time frame. The ensuing 12-month period of March 2020 to February 2021 was considered to be the intra-COVID time frame. RESULTS: There were 49 (0.32%) unique CPA patients pre-COVID and 83 (0.85%) unique CPA patients intra-COVID (P < 0.001) with lower total admissions for any reason during the intra-COVID time frame. Monthly CPA cases were increased (P < 0.03) during the intra-COVID time period (mean 6.9, 95% confidence interval: 5.8-12.7) compared to the pre-COVID time period (mean 4.9, 95% confidence interval: 3.3-8.2). CONCLUSION: During the COVID-19 pandemic, there were decreased overall hospital admissions in the period of mandated shutdowns and isolation. However, we saw an increased rate of CPA admissions compared to the time period prior to the pandemic. Knowledge of such data, trends and circumstances will help keep health-care providers alert and vigilant in identifying children at risk for maltreatment, and may impact child abuse protocols and guidelines.

Presentation, treatment, and outcomes of unifocal and multifocal osseous vertebral Langerhans cell histiocytosis lesions in patients under 18 years old.

This study aims to (1) clinically and radiographically characterize a series of unifocal (single-system single-site) and multifocal (single-system multiple-site) langerhans cell histiocytosis (LCH) lesions in the vertebra and (2) determine the success and recurrence rates with different treatment modalities in a pediatric population at a tertiary children's hospital. Patients younger than 18 years old with a diagnosis of LCH before 1 June 2021 at our institution were reviewed. The inclusion criteria were a unifocal or multifocal vertebral lesion without systemic disease. Clinical presentations, lesion sites, radiographic findings, treatments, complications, recurrence rates, and length of follow-up were reviewed and recorded. Thirty-nine patients had unifocal (36%) or multifocal (64%) vertebral lesions. 44% of patients had vertebral lesions only. The most common clinical presentation was neck or back pain (51%) and difficulty or inability to ambulate (15%). 70 vertebrae were involved in total; 59% cervical, 62% thoracic, 49% lumbar, and 10% sacral. 88% of multifocal patients underwent chemotherapy compared to 60% of unifocal patients. The recurrence rate in the entire cohort was 10%. The median length of follow-up was 5.2 years (0.6-16.8). Chemotherapy is often utilized as a treatment for vertebral LCH lesions regardless of unifocal or multifocal osseous presentation, with good outcomes and low recurrence rates. However other treatments such as observation only and steroid injections may be a better option with smaller and less widespread lesions due to side effects and length of treatment with chemotherapy. Determination of more invasive treatments including surgical excision or fixation will need to be considered on a case-by-case basis. Level of evidence: IV.

An assessment of the diagnosis, treatment, and outcomes of lower extremity stress fractures in pediatric and adolescent populations.

OBJECTIVES: To present one of the first descriptive case series of pediatric and adolescent lower extremity stress injuries, their management, and outcomes in athletes and non-athletes. METHODS: The IRB-approved retrospective study included patients under 18 years at a tertiary children's hospital who were diagnosed with a lower extremity stress fracture/reaction. Demographic data, mechanism of injury, physical exam, radiographic findings, treatment, & outcomes were collected. Descriptive statistical analysis was conducted. RESULTS: Ninety-seven patients with stress injuries on clinical exams and on radiographs or MRI were included. The average age when diagnosed was 11.7 years (range 1.1-18 years) and the most common injuries were to the tibia (n = 33, 28.4%) and the least common involved were the cuneiforms (n = 4, 3.4%). Patients under the age of 14 were more likely to experience cuboid and calcaneal stress injuries (mean age 5.5 and 8.3 years respectively). Nineteen patients (19.6%) had high-risk stress fractures, with the average age of 14.9 years versus 11.6 for those with low risk (p-value = 0.01) and return to activity time being 15 weeks compared to 10.5 (p-value = 0.027). The most common forms of treatment were controlled ankle motion (CAM), walker boots (58.6%), and physical therapy (PT) (38.1%). The mean Lower Extremity Function Score of the patient population was 73.8, indicating no clinically important difference from full functionality. CONCLUSION: Lower extremity stress injuries in this cohort were most seen in the tibia, although patients younger than 14 had a high number of cuboid and calcaneal stress injuries. Those with high-risk stress fractures were older and took longer to recover from when compared to low-risk injuries. Treatment is commonly conservative, with CAM boots and PT being the most frequently utilized interventions and serving as a successful approach to treatment, with patients returning to activity at an average of 11.4 weeks, which is comparable to similar studies.

Treatment and Outcomes of Unifocal and Multifocal Osseous Pelvic Langerhans Cell Histiocytosis Lesions in a Pediatric Population.

Introduction Langerhans cell histiocytosis (LCH) is a rare, clonal disorder characterized by proliferation and tissue infiltration by myeloid dendritic cells, most commonly occurring in pediatric populations. It often manifests as skeletal lesions with possible pelvic involvement. Few studies have characterized and reviewed outcomes after treatment of isolated pelvic LCH lesions. Methods A retrospective single-institution review was conducted on diagnoses of patients younger than 18 with a diagnosis of unifocal or multifocal skeletal LCH lesions involving the pelvis. Clinical presentations, lesion sites, focal classification, radiographic findings, treatments, complications, and recurrence rates were reviewed. Results Twenty patients had unifocal or multifocal LCH pelvic lesions (11 males, nine females). The median age at diagnosis was 3.5 years (0.8-21.6). Eight cases (40%) involved unifocal lesions, and twelve (60%) involved multifocal lesions, with the most common associated skeletal disease occurring at the ilium. 100% of cases had a lytic bone lesion with no pathologic fractures. All cases were treated nonoperatively with chemotherapy medications, corticosteroids, or observation alone. 75% of cases were treated with chemotherapy with a 100% resolution rate. The median length of follow-up was 4.5 years (0.4-16.7).  Conclusion Our study found that chemotherapy alone or chemotherapy with corticosteroid supplementation are appropriate options for unifocal pelvic LCH lesions. In contrast, pelvic lesions that are part of a multifocal presentation may be managed adequately with varied chemotherapy regimens. Corticosteroid therapy and observation alone may also be reasonable for a single organ system, multifocal, skeletal lesions that are anatomically accessible for biopsy and small in number or size.

Early Postoperative Infections After Closed Reduction and Percutaneous Pinning in Type II and Type III Pediatric Supracondylar Humerus Fractures.

BACKGROUND: Supracondylar humerus fractures (SCHF) are the most common elbow fracture type in children, and one of the most common pediatric fracture types overall. Excellent outcomes are generally reported with closed reduction and pinning (CRPP), but the technique involves leaving the pins outside the skin. External pins can act as a nidus for infection. We characterize the infection complications from SCHF treatment at a single-centre tertiary children's hospital over 10 years. This is the largest series on infectious outcomes after CRPP of SCHF reported to date. METHODS: Pediatric patients undergoing CRPP for a type II or type III SCHF from 2011 to 2021 with postsurgical infections within 90 days were identified. Demographic and clinical data were retrieved from medical records. Descriptive statistics were estimated and reported as means or medians with range values or counts with percentages. RESULTS: A total of 18 patients met inclusion criteria, 10 and 8 with type II and III SCHF, respectively. The average age at diagnosis of fracture was 4.7 (2 to 9) years. The average operating time for the index surgery was 29 minutes (12 to 42). The average number of postoperative days until pin removal was 29.8 (18 to 52), and the average number of postoperative days until readmission or visit with symptoms was 38.9 (18 to 77). There was a documented history of a wet cast in 6 patients (33%). Ten (56%) patients presented with fever, and the most common positive culture was methicillin-sensitive Staphylococcus aureus (9, 50%). Thirteen (72%) patients returned to the operating room for incision and drainage. There were no cases with continued complications after the original infection after a median follow-up of 63 days (8 to 559). Infection after CRPP of SCHF is a rare adverse event. In our series, it was most often associated with common pathogens and wet casts. The necessity of return to the operating room will vary with the presentation, but if efficaciously treated afterwards with oral antibiotics, there is a low chance of recurrence or subsequent complications. Patients should be carefully instructed in cast care and demonstrate understanding of risks and complications, and to contact their orthopaedist if their cast demonstrates lack of integrity. LEVEL OF EVIDENCE: Prognostic level IV.

Management of Femur and Tibial Leg Length Discrepancies With a Unilateral External Fixator Is Still Viable When More Advanced Techniques and Hardware Are Unavailable or Cost-Prohibitive.

Introduction Leg length discrepancy (LLD) is an infrequent diagnosis, most commonly occurring congenitally in children and rarely in traumatic incidents in adults. Circumferential external fixators are considered the optimal treatment method, but can be very costly and are not always readily available in less developed nations. The unilateral external fixator predates the circumferential but is more easily available and accessible worldwide and less expensive. This study sought primarily to characterize treatment outcomes using a unilateral external fixator where more advanced forms of treatment for LLD are not available. Secondary objectives included the site of the discrepancy and comparison of etiologies. Methods Data were retrospectively reviewed from January 2010 to December 2017 on patients undergoing unilateral external fixation at our institution. Nineteen patients met the criteria, 14 with congenital LLD and five with lower leg bone loss from trauma. Patient demographics (including gender and age), initial presentation, physical examination findings, radiographic findings, and treatment were collected and saved in an electronic medical record. Results There were 19 cases of LLD overall, with 14 cases on the tibia and 5 on the femur. Three of the five femur cases occurred in the trauma subgroup. There were 15 cases of congenital LLD and five cases of traumatic LLD. The mean overall LLD was 3.9 cm (2.3-5.2). The mean follow-up until healing for the entire cohort was 10 months (5-22). Patients with congenital LLD were younger than those with traumatic LLD (10.2 years versus 22.5 years, p=0.000013), more likely to have a tibial discrepancy (p=0.034), and had a shorter time frame until full healing (7.6 months versus 19 months, p 0.00001). Patients with a tibial LLD were more likely to have a congenital etiology (p=0.0374) and had a shorter time until full healing compared to patients with a femur LLD (8.5 months versus 14 months, p=0.03541). Conclusion  We conclude that bone lengthening utilizing the unilateral external fixator is a good method and is cost-effective for bone lengthening where more advanced techniques are not available or cost-prohibitive. It is simple, and patients and families can collaborate with the surgeon to get a good final result. Patients are generally satisfied and can ambulate well after healing. In a resource-limited environment with cost as a barrier, if used correctly and judiciously, the unilateral external fixator can yield good results.

Plastic multilayered closure versus orthopedic surgeon closure after spinal instrumentation in pediatric neuromuscular scoliosis.

Objective: To compare wound complication rates between orthopedic closure (OC) and plastic multilayered closure (PMC) in patients undergoing primary posterior spinal fusion for neuromuscular scoliosis (NMS). We hypothesize that multilayered closure will be associated with better postoperative outcomes. Methods: We collected data on pediatric patients diagnosed with NMS who underwent first time spinal instrumentation between 1 January 2018 and 31 May 2021. Patient demographics, length of surgery, spinal levels fused and operative variables, wound complication rate, treatments, and need for wound washout were reviewed in depth and recorded. Results: In total, 86 patients were reviewed: 46 with OC and 40 with PMC. There was a significant increase in operating room (OR) time with PMC compared with OC (6.7±1.2 vs 7.3±1.3, p=0.016). There was no difference in complication rate, mean postoperative day of complication or unplanned return to the OR for OC and PMC, respectively. There was a slightly significant increase in the number of patients going home with a drain in the PMC cohort compared with the OC cohort (2.1% vs 15%, p=0.046). Conclusions: PMC demonstrated longer OR times than OC and did not demonstrate a statistically significant reduction in wound complications or unplanned returns to the OR. However, other studies have demonstrated statistical and clinical significance with these variables. Surgical programs should review internal patient volumes and outcomes for spinal fusion in NMS patients and consider if PMC after spinal fusions in pediatric patients with NMS or other scoliosis subtypes is an appropriate option in their institution to minimize postoperative wound complications.
