Background: It is critically important to correctly diagnose hyperinsulinemic hypoglycemia (HH) to avoid neurological sequelae. However, the diagnosis is not always easy in the critical care setting since some patients present with atypical biochemical profiles.Objective and hypotheses: To delineate the range of biochemical data of HH patients at hypoglycemia to help establish a better diagnostic criteria.Method: Biochemical data (...

Background: Bilateral primary pigmented nodular adrenocortical disease (PPNAD) is one of the rare causes of Cushing syndrome, which has traditionally been treated by bilateral adrenalectomy. However, bilateral adrenalectomy mandates life-long adrenal hormone replacement and the patients remain at risk of adrenal failure for the rest of their lives. In adult patients with PPNAD, there have been a few reports of successful unilateral adrenalectomy. However, to our knowledge, the...

We perfomed mutational analyses of the major MODY genes (HNF1A, HNF4A, HNF1B, GCK) on 263 Japanese patients with early-onset, nonobese, MODY-like diabetes mellitus referred to Osaka City General Hospital for diagnosis. Mutations were identified in 103 (35.9%) patients; 57 mutations in GCK; 29, HNF1A; 7, HNF4A; and 10, HNF1B. Compared with these mutation-positive patients, 160 mutation-negative patients were significantly older (P=0.003), and had high...

Background: Approximately 70% of transient neonatal diabetes mellitus (TNDM) are caused by abnormalities in the imprinted locus at chromosome 6q24, and the remaining 30% are caused by heterozygous mutations in the KATP-channel genes, ABCC8 or KCNJ11. Only a few cases of TNDM are reported to be caused by biallelic, recessive mutations in the insulin (INS) gene.Objective and hypotheses: To explore the role of INS gene mutations as a cause of tra...
