Case report: hibernoma, a rare male breast mass.

Hibernomas are rare, benign neoplasms characterized by the presence of brown adipose tissue. Although these tumors may arise in any region of brown fat, they predominantly occur in the thigh, shoulder, back, and neck. Hibernomas are rarely found in mammary tissue, with a higher prevalence in females than males.

Demographic and Risk Factor Differences between Children with "One-Time" and "Repeat" Visits to the Emergency Department for Asthma.

This retrospective study examines demographic and risk factor differences between children who visited the emergency department (ED) for asthma once ("one-time") and more than once ("repeat") over an 18-month period at an academic medical center. The purpose is to contribute to the literature on ED utilization for asthma and provide a foundation for future primary research on self-management effectiveness (SME) of childhood asthma. For the first round of analysis, an 18-month retrospective chart review was conducted on 252 children (0-17 years) who visited the ED for asthma in 2019-2020, to obtain data on demographics, risk factors, and ED visits for each child.
