Background: Panniculitis in patients with dermatomyositis (PDMS) is rare.
Objectives: Assess the clinicopathologic features described for PDMS.
Methods: A systematic review of the PubMed/MEDLINE database was performed.
Background: School physical education is an important population-level health intervention for improving youth fitness. This study estimated the impact of New York City's PE Works program - which included providing PE teachers, training for classroom teachers, and administrative/ teacher support for PE - on student cardiorespiratory fitness as measured by the FitnessGram's 15-meter PACER test for aerobic capacity.
Methods: This longitudinal study (2014/15-2018/19) includes 581 elementary schools (n = 315,999 4th /5th -grade students; 84% non-white; 74% who qualify for free or reduced-price meals, a proxy for socioeconomic status).
Oncocytic adrenal neoplasms, defined by ≥90 % of oncocytic cells, are rare. The significance of oncocytic changes within an adrenal neoplasm remains unclear. A retrospective study of adults who underwent adrenalectomy at a large center identified pure oncocytic neoplasms on final pathology (1997-2022).

- The study reviewed 401 patients who underwent genetic testing for familial hypocalciuric hypercalcemia, with 83% testing negative for mutations and only 11% testing positive.
- Findings showed that patients with mutations had lower median urine calcium levels compared to non-mutated patients, but no significant difference in parathyroid hormone levels across groups.
- The effectiveness of urine calcium measurements and calcium-to-creatinine clearance ratios in identifying familial hypocalciuric hypercalcemia was found to be poor, with areas under the curve indicating low diagnostic performance.
Context: Guidelines suggest performing urine steroid profiling in patients with indeterminate adrenal tumors to make a noninvasive diagnosis of adrenocortical carcinoma (ACC). However, urine steroid profiling is not widely available.
Objective: To determine the accuracy of clinically available serum 11-deoxycortisol, 17OH-progesterone, and 17OH-pregnenolone in diagnosing ACC.
