Rogue Hairs: A Mixed-Method Characterization of a Previously Unreported Entity.

Introduction: We define rogue hairs as unusually long hairs on the face outside of the typical hormone-driven hair-bearing areas. These represent a common and previously undocumented phenomenon. This mixed-method study describes the frequency and clinical features of rogue hairs using a case series, patient survey, and social media analysis. Methods: Clinical cases were identified by dermatologists, and social media platforms were searched for additional cases. Social media comments were reviewed using qualitative thematic analysis. Surveys were administered to patients at an academic dermatology clinic. Results: The case series revealed these hairs are seen in children and adults, men and women, and across races. Of the surveyed patients, 18% reported rogue hairs. Social media analysis highlighted common experiences of sudden appearance, frequent removal attempts, and minimal interaction with dermatologists. Conclusion: This mixed-method study defines rogue hairs on the face, underscoring their prevalence despite their benign nature. While the biological explanation for these hairs remains unknown, the study highlights the potential of social media as a tool for clinical inquiry and enhanced understanding of the patient experience. The study provides evidence-based information for individuals experiencing rogue hairs and prompts future research into the biologic mechanisms underlying this common phenomenon.

This research defines a new term called "rogue hairs" which are unusually long hairs on the face outside of the places where long hairs typically grow. These hairs are common but were not previously reported in medical literature. This study describes how often these hairs occur, where they occur, and other details about the people who have them. People with rogue hairs were identified by dermatologists, and social media platforms were searched to find additional people with these hairs. This study also used surveys and social media websites to learn about people with these hairs. The results showed that these hairs are seen in children and adults, men and women, and across races. Eighteen percent of the surveyed patients reported rogue hairs. Social media analysis showed common experiences of sudden appearance, frequent attempts to remove the hairs, and minimal interaction with dermatologists. The cause for these hairs is not known. This study highlights the potential of social media as a tool for answering clinical questions and better understanding the patient experience. The study provides evidence-based information for individuals experiencing rogue hairs and prompts future research into the causes of this common phenomenon.

Comparing Ultrasound with Magnetic Resonance Imaging in the Evaluation of Subungual Glomus Tumors and Subungual Myxoid Cysts.

Introduction: Subungual myxoid cysts and subungual glomus tumors demonstrate characteristic features on magnetic resonance imaging (MRI) and ultrasound (US). It is not yet well-established whether US is congruent to MRI in diagnostic evaluation of these subungual lesions. Methods: Participants with clinical suspicion for subungual glomus tumors or subungual myxoid cysts were recruited. After clinical evaluation, participants underwent radiography, MRI, and US plus biopsy, aspiration, or excision where possible. Differential diagnoses were revised after review of imaging, and imaging findings were compared to definitive diagnosis by pathology, aspiration, or clinical course. Results: All lesions were visible on both US and MRI and size estimates agreed between the two modalities. US and MRI findings of subungual glomus tumors and subungual myxoid cysts agreed with their known respective imaging characteristics. Conclusions: Diagnosis of subungual myxoid cysts and subungual glomus tumors agreed between US and MRI. We provide sample MRI and US imaging parameters for optimal evaluation of subungual myxoid cysts and glomus tumors. We demonstrate that subungual MRI evaluation can be performed without special equipment, allowing for evaluation by most radiology departments. Lastly, US is user-dependent and may be non-inferior for a sonographer familiar with subungual US.

Nail Sarcoidosis.

This case report describes significant longitudinal ridging and nail plate crumbling on several of a patient's fingernails.

Climate change and pediatric skin health.

Children are known to disproportionately bear the health impacts of climate change, particularly children living in impoverished areas. Owing to their developing physiology and immature metabolism, distinct exposure behaviors, and reliance on adults for care and protection, children are uniquely susceptible to the adverse effects of our warming planet. Herein, we summarize the known impacts of climate change on pediatric skin health, including its effects on atopic dermatitis, vector-borne and other infectious diseases, nutritional deficiencies, and psychodermatoses.

A 68-Year-Old Man With Skin Rash and a Pleural Effusion.

CASE PRESENTATION: A 68-year-old man developed an erythematous, papular, pruritic rash on his right thigh 1 month prior to presentation. It subsequently spread to his other extremities and trunk. He also endorsed fevers of > 38.3°C, night sweats, fatigue, shortness of breath, and a dry cough. He was prescribed triamcinolone 0.1% cream for his rash and azithromycin for presumed community-acquired pneumonia, with no improvement in symptoms. He had a history of relapsing polychondritis for which he was prescribed infliximab and low-dose prednisone. He had never smoked tobacco, did not use alcohol or illicit substances, and had no significant travel history.

Pediatric dermatology and climate change: An argument for the pediatric subspecialist as public health advocate.

The October 2018 report from the United Nations Intergovernmental Panel on Climate Change predicts significant threats to human health secondary to anthropogenic global warming; children have been and will continue to be disproportionately affected by these weather-related changes. Multiple physician groups have acknowledged climate change as a public health issue, calling upon providers to educate their communities about this looming health crisis while also reducing their individual carbon footprints. A significant body of literature has also documented the adverse dermatologic consequences of a warmer planet, highlighting the importance of pediatric dermatologists in addressing climate change. Here, we summarize the rationale for the pediatric dermatologist as public health advocate, providing specific actionable items through which our specialty can positively address the climate change crisis and in turn protect the health of our patients now and in the future.
