The aim of this study was to assess insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-3 (IGFBP-3) concentrations in children with obstructive sleep apnea-hypopnea syndrome (OSAHS) and to compare the results according to disease severity and duration. ⋯ These results suggest that disease duration, but not severity, affects the concentrations of 2 important mediators of growth/development (IGF-1 and IGFBP-3) in children with OSAHS before and after surgery.

Sepsis, defined by the presence of infection and host inflammation, is a lethal clinical syndrome with an increasing mortality rate worldwide. In severe disease, the coagulation system becomes diffusely activated, with consumption of multiple clotting factors resulting in disseminated intravascular coagulation (DIC). When present, DIC portends a higher mortality rate. Understanding the mechanisms that tie inflammation and diffuse thrombosis will allow therapeutic interventions to be developed. The coagulopathy of acute sepsis is a dynamic process that is time and disease burden specific. Whole-blood testing of coagulation may provide more clinically useful information than the classical tests. Natural anticoagulants that regulate thrombosis are downregulated in sepsis. Patients may benefit from the modulation of the coagulation system when systemic inflammation and hypercoagulopathy exist. Proper timing of anticoagulant therapy may ultimately lead to decreased incidence of multisystem organ dysfunction. ⋯ The prevention of DIC in septic patients is a key therapeutic target in preventing death from multisystem organ failure. Stratifying patients for therapy using thromboelastometry, specific markers for DIC, and composite scoring systems is an area of growing research.

Acanthosis nigricans (AN) is a cutaneous disorder associated with various diseases. There are few documented cases of regression of AN. We discuss a case of a 48-year old diabetic woman with resolution of AN after treatment with sitagliptin and pioglitazone.
