Purpose: Gorlin syndrome (GS) is a rare genetic disorder characterized by lifetime risk of basal cell carcinomas (BCCs), skeletal anomalies (SAs), and other extracutaneous neoplasms. There is great variation in disease severity, and a genotype-phenotype correlation has not been well established. Here, we investigate whether patients' clinical characteristics predict disease severity to inform clinical decision making.

Objective: To evaluate the safety and efficacy of the oral NK1 receptor antagonist serlopitant in treating moderate-severe pruritus in EB.
This phase 2, open-label, placebo-controlled examines topical itraconazole as a treatment for basal cell carcinoma.

Objective: To describe the burden of BCCs in patients with BCNS in the United States and identify potential risk factors for BCCs.
Importance: Tumor resistance is an emerging problem for Smoothened (SMO) inhibitor-treated metastatic basal cell carcinoma (BCC). Arsenic trioxide and itraconazole antagonize the hedgehog (HH) pathway at sites distinct from those treated by SMO inhibitors.
Objective: To determine whether administration of intravenous arsenic trioxide and oral itraconazole in patients with metastatic BCC is associated with a reduction in GLI1 messenger RNA expression in tumor and/or normal skin biopsy samples.
Background: Vismodegib is an oral hedgehog-pathway inhibitor approved for advanced basal cell carcinoma (BCC). Although most BCCs are amenable to surgery, excision of large tumors in aesthetically sensitive sites may compromise function or cosmesis.
Objective: We sought to evaluate the reduction in BCC surgical defect area after 3 to 6 months of neoadjuvant vismodegib.
Study Objective: The balance between proteases and antiproteases plays an essential role in the pathogenesis of emphysema. This study was designed to evaluate the impact of all-trans retinoic acid (ATRA) on the balance of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in patients with emphysema.
Design And Setting: As part of a clinical study, ATRA was administered to 20 patients with emphysema for 12 weeks and evaluated for its effects on plasma levels of MMP-9 and TIMP-1.
