A case of erythema ab igne with histopathological features resembling keratosis lichenoides chronica.

This case describes a pediatric patient with a history of ichthyosis vulgaris and global anhidrosis who was diagnosed with erythema ab igne (EAI), a rare dermatosis resulting from chronic heat exposure. After developing progressive, reticulated brown patches on his extremities and abdomen, extensive diagnostic investigations were conducted to rule out autoimmune, vascular, and genetic etiologies. Bloodwork was unrevealing and biopsies showed histologic features closely resembling keratosis lichenoides chronica. Ultimately, after discovering the patient had prolonged exposure to a space heater, the diagnosis of EAI was made. This case underscores the diagnostic challenges in pediatric EAI cases and emphasizes the importance of careful history taking as part of a comprehensive evaluation.

Prevalence and spectrum of infectious and inflammatory dermatologic conditions occurring in pediatric heart transplant patients on a predominantly mTOR-based immune suppressive regimen: A retrospective chart review.

INTRODUCTION: Pediatric heart transplant patients are routinely followed in dermatology clinics due to elevated risk of cutaneous malignancy. However, transplant patients may experience other, non-cancer-related dermatologic conditions including skin infections, inflammatory diseases, and drug eruptions that can cause significant medical and psychosocial comorbidity. METHODS: A retrospective chart review of all pediatric heart transplant patients at Mayo Clinic Children's Center in Rochester, MN, was performed to determine the prevalence and spectrum of non-cancer dermatologic conditions. Statistical analysis was conducted to look for associations between episodes of rejection and skin condition development. RESULTS: Of the 65 patients who received heart transplants under the age of 18 and were followed at Mayo Clinic, 69% (N = 45) were diagnosed with at least one skin condition between transplant and the time of most recent follow-up. Sixty-two percent (N = 40) of patients were diagnosed with an inflammatory skin condition (most commonly acne and atopic dermatitis), 45% (N = 29) with an infectious skin condition (most commonly warts and dermatophyte infection), and 32% (N = 21) with a drug eruption (most commonly unspecified rash and urticaria). No association was found between presence of skin disease and number of rejection episodes. CONCLUSIONS: Non-cancer dermatologic conditions are prevalent within pediatric heart transplant recipients and may directly impact their medical needs and quality of life. Dermatologist involvement in the care of post-transplant pediatric patients is important, not only for cancer screening but also for diagnosis and treatment of common infectious and inflammatory skin conditions.

Adaptation of family-based treatment within an inpatient medical stabilization program for children with eating disorders.

OBJECTIVE: Eating disorders are serious psychiatric conditions predominantly affecting children, adolescents, and young adults. While family-based treatment (FBT) is the gold standard outpatient treatment approach for adolescents with restrictive eating disorders, there is not a universally recognized best practice within higher levels of care. There is a particular dearth of literature detailing recommended psychological and behavioral interventions in the inpatient medical setting. METHOD: The present article provides an account of how FBT principles have been incorporated in Children's Hospital of Orange County at Mission's inpatient medical stabilization program for children and adolescents with restrictive eating disorders. Practical examples illustrate how key FBT tenets are successfully translated into the inpatient multidisciplinary setting. RESULTS: The use of FBT can encourage a unified approach among medical and psychosocial providers and serves to destigmatize patients with eating disorders and associated behaviors. The successes and challenges of FBT implementation are discussed. DISCUSSION: Though anecdotal evidence and preliminary findings support positive outcomes from the implementation of FBT within a pediatric medical stabilization program for patients, families, and staff, research is needed to understand best practices within higher levels of care. Additional research efforts will also help elucidate whether adapted FBT can become a standard of care for patients with restrictive eating disorders in inpatient settings. PUBLIC SIGNIFICANCE: This article describes how a children's hospital has adopted family-based treatment (FBT) for youth who are hospitalized due to an eating disorder. FBT is the most efficacious treatment for youth with eating disorders. This article describes specific examples of how FBT can be implemented within a medical setting. This article will support a greater understanding of FBT principles and guide providers to translate FBT into higher level of care settings.

The effect of foot-stretcher position and stroke rate on ergometer rowing kinematics.

Rowing ergometers are popular tools for general fitness and competitive crew teams. The effect of the equipment set up on the rowing stroke has received limited attention. This study aimed to determine the effects of altering the foot-stretcher position on rowing kinematics across different stroke rates. Eleven college-level rowers took part in this study. A rowing ergometer was modified to allow the height and angle of the foot-stretcher to be adjusted. Seven foot-stretcher positions were tested, each at rates of 22, 26, and 32 strokes per minute. Sagittal plane kinematic waveforms were compared between conditions for all major joints using statistical parametric mapping, and temporal variables were assessed (p < 0.05). Stroke rate was found to affect kinematic patterns for all joints. The effect of the foot-stretcher position was limited to the ankle and hip. Similarly, the timing of events during the rowing stroke was affected by the stroke rate, but not foot position. These results indicate that while some limited changes to the stroke technique can be caused by altering the foot-stretcher position, the changes were largely compensated for by the rowers and are generally smaller than differences between stroke rates.

Percutaneous MR Imaging-Guided Laser Ablation for the Treatment of Symptomatic Cervicofacial Vascular Malformations.

PURPOSE: To evaluate the safety and effectiveness of percutaneous magnetic resonance (MR) imaging-guided laser ablation for the treatment of symptomatic soft tissue vascular malformations (VMs) in the face and neck. MATERIALS AND METHODS: An institutional review board-approved retrospective review was undertaken of all consecutive patients who underwent MR imaging-guided and monitored laser ablation for treatment of symptomatic, cervicofacial soft tissue VM. Preablation and postablation MR imaging findings were independently reviewed. Preablation and postablation VM sizes were documented. Preablation T2 signal characteristics and enhancement patterns as well as postablation change in both signal and enhancement were semiquantitatively assessed. Changes in VM size were compared using a paired t test. RESULTS: Thirteen patients (women, 9; age, 14.5-69.5 years) with 13 VMs were treated for moderate-to-severe pain (n = 4), swelling/mass effect (n = 8), or predominantly cosmesis (n = 1) with 22 total ablation sessions. The baseline maximum VM diameter was 5.7 cm ± 4.2. At baseline, all VMs (100%) demonstrated variable T2-weighted signal hyperintensity and enhancement. For painful VM, the baseline pain score was 8 ± 1. Clinical follow-up was available for 10 patients. Of patients with available follow-up, 3 (100%) treated for moderate-to-severe pain and 7 (100%) treated for swelling/mass effect reported subjective complete or partial symptomatic relief. The patient treated predominantly for cosmetic reasons was lost to follow-up. Two patients (15.4%) experienced minor adverse events by the Society of Interventional Radiology standards. There were no major adverse events. CONCLUSIONS: MR imaging-guided and monitored percutaneous laser ablation is safe and effective for the treatment of symptomatic, cervicofacial VMs.

Imaging of benign cervicofacial vascular anomalies and associated syndromes.

Cervicofacial vascular anomalies can result in morbidity, pain, and cosmetic concerns in affected individuals. Each anomaly has its own unique natural history, treatment, and associations with underlying genetic syndromes. For optimal patient care, it is important for the neuroradiologist to accurately recognize and characterize these entities to ensure appropriate treatment and management. In this review, we discuss the general characteristics, classifications, and imaging features associated with the most common vascular anomalies such as hemangiomas, arteriovenous malformations and fistulas, capillary malformations, venous malformations, and lymphatic malformations in the context of associated syndromes. Additionally, we discuss novel imaging techniques that aid in identifying these vascular anomalies.
