RESUMO
OBJECTIVE: To determine if children who present with an elbow flexion contracture (EFC) from brachial plexus birth injury (BPBI) are more likely to develop shoulder contracture and undergo surgical treatment. STUDY DESIGN: Retrospective review of children <2 years of age with BPBI who presented to a single children's hospital from 1993 to 2020. Age, elbow and shoulder range of motion (ROM), imaging measurements, and surgical treatment and outcome were analyzed. Patients with an EFC of ≥10° were included in the study sample. Data from 2445 clinical evaluations (1190 patients) were assessed. The final study cohort included 72 EFC cases matched with 230 non-EFC controls. Three patients lacked sufficient follow-up data. RESULTS: There were 299 included patients who showed no differences between study and control groups with respect to age, sex, race, ethnicity, or functional score. Patients with EFC had 12° less shoulder range of motion (95% CI, 5°-20°; P < .001) and had 2.5 times the odds of shoulder contracture (OR, 2.5; 95% CI, 1.3-4.7; P = .006). For each additional 5° of EFC, the odds of shoulder contracture increased by 50% (OR, 1.5; 95% CI, 1.2-1.8; P < .001) and odds of shoulder procedure increased by 62% (OR, 1.62; 95% CI, 1.04-2.53; P = .03). Sensitivity of EFC for predicting shoulder contracture was 49% and specificity was 82%. CONCLUSIONS: In patients with BPBI <2 years of age, presence of EFC can be used as a screening tool in identifying shoulder contractures that may otherwise be difficult to assess. Prompt referral should be arranged for evaluation at a BPBI specialty clinic, because delayed presentation risks worsening shoulder contracture and potentially more complicated surgery.

PURPOSE: The treatment of ganglion cysts of the wrist remains understudied in the pediatric population, with the literature showing variable recurrence rates following different interventions. This study sought to determine whether surgical and nonsurgical management of pediatric ganglion cysts was associated with improved resolution rates when compared to observation alone. METHODS: We identified 654 cases of pediatric ganglion cysts treated across 5 institutions between 2012 and 2017. The mean age at presentation was 11.6 ± 5.2 years. Of the patients, 315 had >2 years (mean, 50.0 months) of follow-up, either via chart review or telephone callbacks. There were 4 different treatment groups: (1) observation, (2) cyst aspiration, (3) removable orthosis, and (4) surgical excision. RESULTS: For patients followed >2 years, the cyst resolved in 44% (72/163) of those observed. Only 18% (9/49) of those treated with aspiration resolved, and 55% (12/22) of those treated with an orthosis resolved. Surgical excision was associated with resolution of the cyst in 73% (59/81) of patients. Observation had higher rates of resolution compared to aspiration. Orthosis fabrication and observation had similar rates of cyst resolution. Surgery had the highest rates of resolution when compared to observation and aspiration. Patients older than 10 years were less likely to have the cyst resolve with observation (35%; 28/80) than those younger than 10 years (53%; 44/83) at >2 years of follow-up. CONCLUSIONS: This study did not find evidence that nonsurgical treatments were associated with improved rates of cyst resolution compared to observation alone in a large pediatric sample. Surgical excision had the overall highest rate of resolution. Despite the costs and increased clinic time of orthosis fabrication and aspiration, these treatments were not associated with improved rates of cyst resolution in pediatric ganglion cysts compared to observation, with aspiration having higher rates of recurrence compared to observation. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

PURPOSE: Microsurgical nerve reconstruction has been advocated between 3 and 9 months of life in select patients with brachial plexus birth injury (BPBI), yet some patients undergo indicated surgery after this time frame. Outcomes in these older patients remain poorly characterized. We analyzed outcomes of nerve reconstruction performed after 9 months of age and hypothesized that (1) Active Movement Scale (AMS) scores improve after surgery, and (2) there are no differences in AMS scores between patients undergoing nerve transfers versus those undergoing nerve grafting. METHODS: From 2000 to 2014, 750 patients at 6 U.S. centers were prospectively enrolled in a multicenter database. We included patients treated with nerve reconstruction after 9 months of age with minimum 12 months' follow-up. Patients were evaluated using AMS scores. To focus on the results of microsurgery, only outcomes prior to secondary surgery were analyzed. We analyzed baseline variables using bivariate statistics and change in AMS scores over time and across treatment groups using linear mixed models. RESULTS: We identified 32 patients (63% female) with median follow-up of 29.8 months. Median age at microsurgery was 11.2 months. Twenty-five (78%) had an upper trunk injury. Compared with before surgery, total AMS scores improved modestly at 1 year and 2 or more years follow-up. At 1 year follow-up, AMS scores improved for shoulder function (abduction, external rotation) and elbow flexion. Between-group comparisons found no differences in total AMS scores or AMS subscales between graft and transfer groups at 1 year or 2 or more years after surgery, so we cannot recommend one strategy over the other based on our findings. CONCLUSIONS: Overall, nerve reconstruction in patients with BPBI after 9 months of age resulted in improved function over time. There was no difference in outcomes between nerve transfer and nerve graft groups and 1 or 2 or more years follow-up. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

(1) Background: A reliable non-invasive distinction between low- and high-risk pancreatic intraductal papillary mucinous neoplasms (IPMN) is needed to effectively detect IPMN with malignant potential. This would improve preventative care and reduce the risk of developing pancreatic cancer and overtreatment. The present study aimed at exploring the presence of autoreactive antibodies in the blood of patients with IPMN of various grades of dysplasia. (2) Methods: A single-center cohort was studied composed of 378 serum samples from patients with low-grade IPMN (n = 91), high-grade IPMN (n = 66), IPMN with associated invasive cancer (n = 30), pancreatic ductal adenocarcinoma (PDAC) stages T1 (n = 24) and T2 (n = 113), and healthy controls (n = 54). A 249 full-length recombinant human protein microarray was used for profiling the serum samples. (3) Results: 14 proteins were identified as potential biomarkers for grade distinction in IPMN, yielding high specificity but mediocre sensitivity. (4) Conclusions: The identified autoantibodies are potential biomarkers that may assist in the detection of malignancy in IPMN patients.
RESUMO
BACKGROUND AND PURPOSE: The current prognostic biomarker of functional outcome in brachial plexus birth palsy is serial clinical examination throughout the first 6 months of age. This can delay surgical treatment and prolong parental anxiety in neonates who will recover spontaneously. A potentially superior biomarker is a volumetric proton density MRI performed at clinical presentation and within the first 12 weeks of life, providing a high spatial and contrast resolution examination in 4 minutes. METHODS: Nine neonates ranging in age from 4 to 9 weeks who presented with brachial plexus birth palsy were enrolled. All subjects underwent non-sedated 3 Tesla MRI with Cube Proton Density MRI sequence at the same time as their initial clinical visit. Serial clinical examinations were conducted at routine 4 week intervals and the functional performance scores were recorded. MRI findings were divided into pre-ganglionic and post-ganglionic injuries and a radiological scoring system (Shriners Radiological Score) was developed for this study. RESULTS: Proton Density MRI was able to differentiate between pre-ganglionic and post-ganglionic injuries. Radiological scores (Shriners Radiological Score) correlated better with functional performance at 6 months of age (P = .022) than the initial clinical examinations (Active Movement Scale P = .213 and Toronto P = .320). CONCLUSIONS: Rapid non-sedated volumetric Cube Proton Density MRI protocol performed at initial clinical presentation can accurately grade severity of brachial plexus birth palsy injury and predict functional performance at 6 months of age.
