Comparative Analysis of the Collapsibility Index and Distensibility Index of the Inferior Vena Cava Through Echocardiography with Pulse Pressure Variation That Predicts Fluid Responsiveness in Surgical Patients: An Observational Controlled Trial.

Objective: The objective for the present study was to compare the collapsibility (IcIVC) and distensibility (IdIVC) indices of the inferior vena cava with pulse pressure variation (PPV) and determine the accuracy and cutoff points of IcIVC and IdIVC that best predict response to intravenous fluid therapy in surgical patients.

Design: Observational, prospective, nonblinded, single center.

Setting: Hospital do Servidor Público Estadual de São Paulo, in São Paulo, Brazil.

Interdomal-columellar myolipoma: discovered at rhinoplasty.

Unlabelled: Tumors of the adipose tissue located in the nose are extremely rare. This report draws attention to the first case of nasal tip-columellar myolipoma described in the literature. During an open rhinoplasty, the authors elevated the columellar flap and approached the tip, where they found a misdiagnosed 2 × 1 cm fatty mass wedged into the interdomal space continuing between the middle and medial cruses of the alar cartilages, which were laterally dislocated.
