Background: Since the introduction of continuous subcutaneous insulin infusion (CSII), the benefits have been numerous. However, adverse events (AEs) are experienced by up to 40% of users per year, exposing them to potentially fatal risks. The available evidence on the variables that trigger AEs associated with CSII remains limited, indicating the importance of studies on the subject.

Use of a Sodium-Glucose Cotransporter 2 Inhibitor, Empagliflozin, in a Patient with Rabson-Mendenhall Syndrome.

Introduction: Among the insulin resistance syndromes that lead to diabetes mellitus in young people, Rabson-Mendenhall syndrome (RMS; OMIM # 262190) is an autosomal recessive inherited disease caused by an insulin receptor mutation (INSR; 147,670). Due to the rarity and complexity of the disease, we have few therapeutic alternatives other than insulin with clinical studies with robust evidence. Some reports suggest the adjunct use of metreleptin, metformin, and pioglitazone with improved glycemic control, however, with results still unsatisfactory for the desirable glycemic targets for this age group.

Time in range: a new parameter to evaluate blood glucose control in patients with diabetes.

The International Consensus in Time in Range (TIR) was recently released and defined the concept of the time spent in the target range between 70 and 180 mg/dL while reducing time in hypoglycemia, for patients using Continuous Glucose Monitoring (CGM). TIR was validated as an outcome measures for clinical Trials complementing other components of glycemic control like Blood glucose and HbA1c. The challenge is to implement this practice more widely in countries with a limited health public and private budget as it occurs in Brazil.

Pancreatic Agenesis due to Compound Heterozygosity for a Novel Enhancer and Truncating Mutation in the PTF1A Gene.

Neonatal diabetes, defined as the onset of diabetes within the first six months of life, is very rarely caused by pancreatic agenesis. Homozygous truncating mutations in the PTF1A gene, which encodes a transcriptional factor, have been reported in patients with pancreatic and cerebellar agenesis, whilst mutations located in a distal pancreatic-specific enhancer cause isolated pancreatic agenesis. We report an infant, born to healthy non-consanguineous parents, with neonatal diabetes due to pancreatic agenesis.
