Abstract
Chromosome 6 abnormalities such as paternal uniparental isodisomy, paternal 6q24 duplication, and maternal DMR (differentially methylated region) hypomethylation are a common cause of transient neonatal diabetes mellitus (TNDM). Oral sulfonylurea (SU) is used off-label to treat permanent neonatal diabetes mellitus owing to potassium channel mutation but has not been evaluated in TNDM. Our objective was to evaluate the efficacy and safety of SU therapy in chromosome 6-related TNDM. Description of 3 case reports and literature review was the subject of the study. SU therapy was successful in 2 patients (initiated during neonatal life in 1 patient and during relapse in the other) but failed in the other despite the use of high dosage. The literature review identified 11 cases of patients with chromosome 6-related TNDM treated with SU, including 4 treated before remission and 7 after the relapse. SU therapy was consistently effective, although 4 patients treated after the relapse required multiple oral medications. None of the patients needed associated insulin therapy. No side effects of SU or complications of diabetes were reported. SU seems effective and safe in chromosome 6-related TNDM treatment when used to treat the initial episode of diabetes or the relapse. It improves patients' and families' quality of life. SU is available only as oral tablets. A pediatric dosage form would facilitate the treatment of neonates and infants.

Abstract
A 40-year-old diabetic man was admitted to our hospital for poor glycemic control. During hospitalization, he took 42 mg glimepiride and 50 mg zolpidem as a suicide attempt. The following day, the creatine kinase-MB fraction and troponin I levels were elevated to 112 IU/L and 8.77 ng/mL, respectively, without any electrocardiographic abnormalities. The patient recovered completely without any complications. Four weeks later, coronary computed tomography angiography and myocardial perfusion scintigraphy revealed moderate one-vessel coronary disease without the evidence of myocardial ischemia or old infarction. Cardiac-specific markers must be considered in sulfonylurea-induced hypoglycemic patients, particularly when the patient is unconscious and does not exhibit any clinical manifestations.
