Background: Neuroblastoma is the most common extracranial solid tumor in children, with about half of cases classified as high risk. Treatment varies by risk level, with high-risk patients undergoing aggressive multimodal therapy. While long-term survival has improved, survivors face significant risks of late treatment effects, including adrenal insufficiency.

Metyrapone is commonly used in the initial management of Cushing's syndrome to reduce hypercortisolemia, but its optimal dosage and timing can vary significantly between patients. Currently, there are limited guidelines on adjustment methods for its administration to individual needs. This study aimed to evaluate responsiveness of each patient to metyrapone and identify the patient characteristics associated with the indices of cortisol responsiveness following a low-dose metyrapone.

Cytochrome P450 17A1 (CYP17A1) catalyzes two enzymatic reactions in the biosynthesis of dehydroepiandrosterone (DHEA) from pregnenolone. In pregnant humans, the adrenal gland is responsible for DHEA biosynthesis, which is then sulfated by SULT2A1 and released into the bloodstream. This sulfated DHEA is subsequently taken up by the placenta and deconjugated to serve as a precursor for estrogen biosynthesis.

Department of Diabetes, Metabolism and Endocrinology, Japan Labor Health and Safety Organization, Tokyo Rosai Hospital, Tokyo, JPN.
Severe hypoglycemia (SH) is a significant risk, particularly in the elderly, and adrenal insufficiency (AI) may be a contributing factor. This study examines six cases of late dumping syndrome (LDS)-induced reactive hypoglycemia (RH), with AI as a potential trigger. Three of the six patients were diagnosed with AI, and one experienced a hypoglycemic coma.

Background: Anaplastic lymphoma kinase () rearrangement, the most common oncogenic rearrangement in lung adenocarcinoma, occurs in approximately 5% of non-small cell lung cancer (NSCLC) patients. gene is the most common partner of rearrangement, and distinct EML4-ALK fusions differ in their responsiveness to ALK tyrosine kinase inhibitors. However, the concurrence of two rearrangements in one patient and whose response to ALK-TKIs have rarely been reported so far.
