Anterior chest wall regression after Nuss bar removal in adult patients with pectus excavatum.

Objective: Pectus excavatum repair with the Nuss procedure can be successfully performed in adults. After removing the pectus bars, the anterior chest wall may regress to some degree. The purpose of this study was to clarify the amount of improvement and regression of the chest wall after bar removal.

Analysis of chest wall elevation after the Nuss procedure using 3D body scanning technique in patients with pectus excavatum.

Purpose: For the evaluation of the chest wall deformity, we adopted a non-invasive 3D body scanning system. The objective of this study is to evaluate surgical effect on the whole thorax using 3D scanning technique before and after Nuss procedure.

Methods: We performed 3D body scanning using Structure Sensor (Occipital Inc, USA) in 11 symmetric patients (average age 13 ± 3.

Chondrotomy and sternotomy combined with the Nuss procedure for severe asymmetric pectus excavatum: how to do it.

The correction of severe asymmetric pectus excavatum is still challenging, especially for adults with a rigid thorax. For the repair of asymmetric cases, we introduce our surgical techniques added to the Nuss procedure. Chondrotomy of the depressed and deformed costal cartilage to elevate the depressed side was performed in a 42-year-old female patient.

Magnetic particle transport through organogel - an application to DNA extraction.

An observation that magnetic particles are transported through organogel encouraged us to investigate its feasibility of liquid-phase displacement in DNA extraction using magnetic particles. Organogel for this study was prepared from a gelator, 12-hydroxystearic acid (12-HSA), and an apolar solvent, methylphenylsilicone oil. The organogel is a gel-like solid material with hydrophobic and elastic properties.

Rib osteotomy with the Nuss procedure for the repair of adult pectus excavatum.

For the Nuss procedure in adult patients with pectus excavatum, sufficient sternal elevation is difficult due to the rigid chest wall. To solve the problem, we present a novel rib osteotomy procedure. From the skin incisions on the lateral chest which are the common approach for the Nuss procedure, a surgical drill is used to incise bilateral anterior half of the rib cortex after installing the pectus bars.
