Rina Wassermann-Dozorets, Menachem Rubinstein
Many types of tumor cell are devoid of the extracellular matrix proteoglycan osteoglycin (Ogn), but its role in tumor biology is poorly studied. Here we show that RNAi of Ogn attenuates stress-triggered cell death, whereas its overexpression increases cell death. We found that the transcription factor C/EBPβ regulates the expression of Ogn. C/EBPβ is expressed as a full-length, active form (LAP) and as a truncated, dominant-negative form (LIP), and the LIP/LAP ratio is positively correlated with the extent of cell death under stress...

BACKGROUND: Cleft Lip with or without Palate (CL/P) is present in approximately 1 in 500-700 live births, representing the most common congenital craniofacial anomaly. Previously, we developed a unique murine model with compound Pbx deficiency that exhibits fully penetrant CL/P. To investigate the possibility of tissue repair at an early gestational stage, we designed a minimally invasive surgical approach suitable for intrauterine repair using Wnt9b-soaked collagen microspheres to restore craniofacial developmental programs for cleft correction...

Cross lip vermilion flap is a myomucosal flap that uses lower red lip to augment deficient upper lip vermilion. Technical note that helps in imitating upper lip tubercle structure is presented. Appropriate patient selection to prevent unfavorable results such as color mismatch, local vermilion excess, and lower lip thinning are presented. Indirect benefits of this flap for decreasing upper incisor tooth show and better balance of upper/lower lip thickness are discussed.

INTRODUCTION: Today, reconstructive surgeons offer an array of options to reconstruct the lip defects. Herein we present our experience of using free double-paddle peroneal flaps for extensive lip defect reconstruction. PATIENTS AND METHODS: From 1996 to 2014, 16 patients with extensive lip defects after tumor ablation were included. Free double-paddle peroneal flaps were used for reconstructions. In terms of flap design, one skin paddle superiorly placed on the lateral lower leg was used to reconstruct intraoral defects, whereas the other was inferiorly located and was used to reconstruct extraoral defects...

Facial rejuvenation, particularly lip augmentation, has gained widespread popularity. An appreciation of perioral anatomy as well as the structural characteristics that define the aging face is critical to achieve optimal patient outcomes. Although techniques and technology evolve continuously, hyaluronic acid (HA) dermal fillers continue to dominate aesthetic practice. A combination approach including neurotoxin and volume restoration demonstrates superior results in select settings.

BACKGROUND: A deviated nose is a common deformity encountered in rhinoplasty. Over the past several decades, a variety of rhinoplasty techniques have been described focusing on the classification of bony and cartilaginous deviation. Nevertheless, corrective rhinoplasty is still a challenging procedure even for experienced surgeons because of the high recurrence rate of deviation. In attempt to reduce the recurrence rate, the author systematized the complex procedures by using a single technique regardless of the classification of a deviation...

Expanded polytetrafluoroethylene (ePTFE) has been extensively used for facial soft tissue augmentation procedures, and is regarded as safe and reliable and suitable as a permanent implant. This implant is generally used in the lower third of the face for lips filling, nasal augmentation, nasolabial folds and chin augmentation, and rarely for congenital or acquired depressed deformities of the face. The aim of the present study was to assess the effects of ePTFE in congenital or acquired depressed deformities of the face...

The patients with secondary bilateral cleft lip and nasal deformity always suffer from a serious part of the horizontal and vertical soft tissue deficiencies in the upper lip and nose, especially the columella. Normally, the Abbe flap is used to increase the soft tissue volume of upper lip. However, how to reconstruct the sever columella deficient, how to make full use of the Abbe flap and the remaining soft tissue of the upper lip, are always the problems that need to be solved by plastic surgeons. Twenty-nine patients with secondary bilateral cleft lip and severe columella deficiency were simultaneously reconstructed with several local flaps like dominos that was called "Domino sliding flaps...

BACKGROUND: Secondary cleft lip nasal deformity is a complex deformity, and the variety of recommended techniques used to correct this deformity attests to it. Much of the nasal deformity can be attributed to an abnormal lower lateral cartilage. This study presents our experience with applying a lateral crural turnover flap with a sandwiched strut graft in adjunct with other procedures to correct unilateral secondary cleft lip nasal deformity. METHODS: A retrospective review was conducted of 20 cases of unilateral cleft lip patients undergoing secondary rhinoplasty with lateral crural turnover flap with strut graft...
