Ultrasonic- and Ultrasound-assisted Improvement of Silhouette of the Torso: Bone Structure High-definition Remodeling (Part I).

Background: High-definition liposculpture allowed plastic surgeons to achieve better aesthetic results by carving the underlying muscles and contours in a new way. Several authors have improved the original technique by adding other procedures and new technologies. We designed a new improvement by incorporating bone transformation surgery to overcome the lack of silhouette at the waist and, as a result, optimize the breast-waist-hip ratios. Methods: We carried out a prospective multicenter study, with five different surgeons performing the same rib remodeling technique for waist definition. We used an ultrasonic piece for costal corticotomy and real-time ultrasound imaging to perform green-stick fractures over the last two or three floating ribs. Ours is a new technique based on the prior one described by Kudzaev. Results: We reported 131 consecutive patients who were enrolled in this study. Waistline diameter decreased an average of 8 cm after surgery (P < 0.05). Most patients were women (n = 125, 95.4%). No major complications were reported. Most common complication was prolonged pain, with only three cases of contour asymmetry, all of which were attributable to noncompliance of constantly wearing the corset + compressive garments. Patients reported a high satisfaction rate and fast recovery (Body-QoL survey). Conclusions: Ultrasonic- and ultrasound- assisted indentation surgery of the thorax is a safe and reliable technique for waistline definition, with a high satisfaction rate, almost-invisible scars, and minimal risk for complications. Incorporation of high-definition liposculpture to rib remodeling opens up a new horizon for bone structure modification surgery (S-high-definition remodeling) that can be safely performed for patients who seek better aesthetic outcomes in body contouring.

Prevalencia del habito de fumar en tripulantes de aeronaves: estudio preliminar / Prevalence of smoking among aircrews: a preliminary study

Se realiza un estudio sobre tabaquismo para determinar la prevalencia del hábito de fumar en tripulantes de aeronaves, ya que constituyen un grupo poblacional altamente expuesto. El 53,9 por ciento total de encuestados mostró el hábito de fumar (el 55,3 por ciento correspondió al sexo masculino y el 50,8 por ciento al femenino). Se encontró una fuerte asociación estadísticamente significativa en relación con la cantidad de cigarillos fumados diariamente en las diferentes categorías ocupacionales. El 30 por ciento se consideró como fuertes fumadores. En los mayores de 40 años de edad, el 80 por ciento llevaba 15 o más años de consumo tabáquico, y en los menores de 40 años, el 50 por ciento . Se necesitarán aplicar técnicas de cesación que permitan lograr una disminución significativa de la prevalencia del hábito de fumar
