A confirmed case of xylazine-induced skin ulcers in a person who injects drugs in Miami, Florida, USA.

BACKGROUND: Xylazine is an alpha-2 adrenergic receptor agonist that has emerged as a contaminant in the illicit drug supply of fentanyl. Xylazine use may be suspected in naloxone-resistant overdoses and atypical, chronic wounds in people who use drugs (PWUD). This case is unique because it is the first case to our knowledge describing wound care for a xylazine-induced wound with a confirmatory xylazine test strip (XTS) in the setting of a syringe services program (SSP) and in the state of Florida. CASE PRESENTATION: A 43-year-old woman with a past medical history of severe opioid use disorder and stimulant use disorder presented to a student-run clinic at a Miami SSP for wound care. She had multiple ulcerations diffusely over her bilateral forearms with surrounding erythema and warmth. Seven weeks later, she presented to clinic again for wound care because her wounds had progressed. At this visit, a XTS was used to confirm the presence of xylazine in her urine. Wound care management and harm reduction strategies employed at both visits were informed by best clinical judgement due to lack of formal guidelines at the time. Wound outcomes are unknown as the patient has not returned to clinic. CONCLUSIONS: Many PWUD at highest risk for acute and chronic health consequences of xylazine-adulterated fentanyl do not have access to healthcare outside of low barrier clinics and SSPs due to lack of insurance or mistrust of the traditional healthcare system due to stigma. There is an urgent need for access to XTS for PWUD and clinical practice guidelines for the treatment of xylazine-related wounds in outpatient clinics.

Gait Analysis Characteristics in Relapsed Clubfoot.

BACKGROUND: Relapse rates of clubfoot deformity after initial correction range between 19% and 68% regardless of treatment approach. Most studies focus on relapse before age 4. Little research has focused on late clubfoot relapse. The purpose of this study was to compare the gait characteristics of children with late clubfoot relapse (age ≥5 y) following treatment with the Ponseti method only compared with intra-articular and extra-articular surgeries. METHODS: A retrospective review was conducted of all patients with idiopathic clubfoot ≥5 years old who underwent computerized gait analysis for clubfoot relapse between 2001 and 2021. Joint range of motion, muscle strength, gait kinematics, and kinetics were compared among 3 groups based on prior clubfoot treatment: (1) Ponseti casting, (2) Extra-articular (EA) surgery, and (3) Intra-articular (IA) surgery. RESULTS: Sixty-eight subjects (107 feet) were included (39 bilateral). Thirty-one percent of feet had been treated with Ponseti casting alone; 57% had IA surgery, and 12% had EA surgery. The average age when presenting with late relapse was 8.2 years, 9.0 years and 10.7 years for the Ponseti, and IA and EA groups, respectively. The IA group had greater passive dorsiflexion than the other 2 groups (P<0.002), greater inversion weakness than the other 2 groups (P<0.0001), greater dorsiflexion during the stance phase of gait compared with the Ponseti group (P=0.001), and lower maximum power production at push-off compared with the other 2 groups (P=0.009). CONCLUSION: Late relapse can occur after all types of clubfoot correction. Consistent with existing literature, patients who have undergone posteromedial release surgery have significantly greater plantarflexor weakness resulting in poorer plantarflexor moment and power production during gait. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Development of a Group Curriculum for Children With Congenital Upper Limb Difference (CULD) and Their Caregivers.

Caring for patients with congenital upper limb differences (CULD) requires an understanding of unique psychosocial challenges. The study purpose was to describe the needs of children with CULD and their caregivers to develop a group curriculum. This mixed-method study included 13 mothers and one father of children with CULD (age 3 months to 14 years; mean 7.2 ± 4.3 years) using Patient-Reported Outcomes Measurement Information System Parent Proxy Reports and caregiver interviews. Patient-Reported Outcomes Measurement Information System Peer Relationships (M = 48.1 ± 10.9) and Pain Interference (M = 44.5 ± 7.5) T-scores were average with below average scores for Physical Function: Upper Extremity (M = 31.9 ± 12.1). Caregivers expressed high interest in groups to create community and mutual support covering themes of responding to questions from strangers, social and coping skills, building self-confidence, accessing resources, advocacy skills, and advice from adults with CULD. Access to a support group with a curriculum addressing CULD-related patient and family needs may improve care.

Investigating the Determinants of Nonaccidental Trauma Evaluation in Pediatric Femur Fractures.

BACKGROUND: Femoral fractures in children have the highest probability for abuse after skull fractures and humeral shaft fractures. However, the reported proportion of pediatric femur fractures that result from nonaccidental trauma (NAT) varies in the literature from 2% to 60%. The purpose of this study was to determine the patient characteristics associated with a physician's decision to conduct a NAT workup and challenge universal clinical practice guidelines stating that all children younger than 3 years with a diaphyseal femur fracture be evaluated for NAT. METHODS: A retrospective review was conducted on patients aged 0 to 36 months diagnosed with a femur fracture between January 1, 2004, and April 9, 2019, at our institution. NAT was defined as a diagnosis of trauma that was nonaccidental in the medical chart after a positive workup by skeletal survey, ophthalmological examination, or other appropriate referral made by the institution's child abuse and neglect team. Patients with incomplete medical records were excluded. RESULTS: A total of 299 patients were identified, and 22 were excluded. 71% (197/277) were screened for NAT. Patients younger than 1 year were significantly more likely to undergo a NAT workup (P = 0.009; Odds Ratio [OR], 2.3; 95% CI, 1.2 to 4.4) and receive a positive result from the NAT workup (P < 0.0005; OR, 11.3; 95% CI, 4.6 to 27.4). Additional injuries were also a significant predictor of a positive NAT workup (P < 0.001; OR, 5.3; 95% CI, 2.4 to 11.9). Patient race/ethnicity, sex, and fracture type were not markedly associated with the physician's decision to conduct a NAT workup. CONCLUSIONS: Infants younger than 1 year with a femur fracture and children younger than 3 years presenting with a femur fracture and another injury are at increased risk of possible NAT. While clinical practice guidelines may minimize racial bias in NAT evaluation, this study demonstrates that universal NAT workups for walking-age children in the absence of other evidence of abuse may be unnecessary. LEVEL OF EVIDENCE: This is a Level III retrospective cohort study.

A Confirmed Case of Xylazine-Induced Skin Ulcers in a Person Who Injects Drugs in Miami, Florida, USA.

Background: Xylazine is an alpha-2 adrenergic receptor agonist that has emerged as a contaminant in the street drug supply of fentanyl. Xylazine use may be suspected in naloxone-resistant overdoses and atypical, chronic wounds in people who inject drugs (PWID). This case is unique because it is the first case to our knowledge describing wound care for a xylazine-induced wound with a confirmatory xylazine test strip (XTS) in the setting of a syringe services program (SSP) and in the state of Florida. Case Presentation: A 43-year-old woman with a past medical history of severe opioid use disorder and stimulant use disorder presented to a student-run clinic at the IDEA Miami SSP for wound care. She had multiple ulcerations diffusely over her bilateral forearms with surrounding erythema and warmth. Seven weeks later, she presented to clinic again for wound care because her wounds had progressed. At this visit, a XTS was used to confirm the presence of xylazine in her urine. Wound care management and harm reduction strategies employed at both visits are discussed below. Wound outcomes are unknown as the patient has not returned to clinic. Conclusions: Many PWID at highest risk for acute and chronic health consequences of xylazine-adulterated fentanyl do not have access to healthcare outside of low barrier clinics and SSPs due to lack of insurance or mistrust of the traditional healthcare system. There is an urgent need for access to XTS for PWID and clinical practice guidelines for the treatment of xylazine-related wounds in outpatient clinics.

Prevalence of xylazine among people who inject drugs seeking medical care at a syringe services program clinic: Miami, Florida, 2023.

Background: We aimed to report the preliminary xylazine prevalence among people who inject drugs (PWID) treated at a student-run free clinic in Miami, FL, USA and to identify characteristics associated with screening positive for xylazine. Methods: A retrospective chart review of 59 patients presenting to a syringe services program (SSP) clinic in was conducted between April 27th and August 17th, 2023. We measured presence of xylazine with rapid visual immunoassay strips on patient urine samples. Results: Xylazine was present in 55.9 % (33/59) of urine samples including 2 without detected opioids. Xylazine presence was significantly associated with unsheltered homelessness (p = 0.018), presence of wound(s) (p = 0.008), and testing positive for hepatitis C antibody (p = 0.014), fentanyl (p = 0.005) and MDMA (p = 0.002). Conclusions: A high prevalence of xylazine in the Southeastern United States furthers evidence of the geographical spread of xylazine and rapidly evolving illicit drug supply. Widespread xylazine screening is urgently needed to inform people who inject drugs and to studyinterventions to minimize harms associated with xylazine.
