Most studies of stem cell regeneration have focused on differentiation of ASCs and their building block function; however, the paracrine effects of ASCs should also be the focus of attention.

BACKGROUND AND OBJECTIVES: Recently developed laser lipolysis systems have been disappointing because they require more time to remove the same amount of fat than other liposuction methods. A new Nd:YAG laser has been introduced that uses the 1,444 nm wavelength, better absorbed by fat. STUDY DESIGN/MATERIALS AND METHODS: This study consisted of two protocols. The first protocol was an in vivo minipig model. Four 10x10 cm(2) areas were treated on the back of the first minipig. Using the same tot

PURPOSE: To report an epidemic of O. anthropi pseudophakic endophthalmitis. METHODS: The medical records of nine patients with culture-proven O. anthropi endophthalmitis were reviewed. RESULTS: The presenting features were compatible to chronic endophthalmitis. Two patients showed coinfections with P. acnes. Antibiotics sensitivity test revealed susceptibility to quinolones. Pars plana vitrectomy (PPV) with partial capsulectomy (PC) cured infections in seven patients without coinfection of P. ac

OBJECTIVE: Craniofacial deformities (CFDs) frequently accompany midfacial hypoplasia. The authors evaluated characteristics of maxillary sinuses that had CFDs with variable degrees of midfacial hypoplasia. STUDY DESIGN: Cross-sectional survey with chart review. SETTING: Department of Plastic and Reconstructive Surgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea. SUBJECTS AND METHODS: We investigated 40 patients with CFDs having midfacial hypoplasia. Study

UNLABELLED: : Because adipose-derived stem cells (ASCs) are usually expanded to acquire large numbers of cells for therapeutic applications, it is important to increase the production yield and regenerative potential during expansion. Therefore, a tremendous need exists for alternative ASC stimuli during cultivation to increase the proliferation and adipogenic differentiation of ASCs. The present study primarily investigated the involvement of megestrol acetate (MA), a progesterone analog, in th

Accurate reduction and stable fixation are important in the treatment of frontal sinus fracture. Usually, metal plates and screws were used because of easy handling and delicate fixation. However, palpability and possibility for secondary operation for plate removal were shortcomings. For improving these problems, we used absorbable mesh plate for fixation of reduced frontal bones.In this study, 14 patients with frontal sinus fracture were treated by open reduction and rigid fixation using absor

We demonstrated that hypofractionated RT with VMAT served to reduce radiation-related morbidities in prosthetic reconstruction from a clinicopathologic perspective, compared to conventional RT. It may offer a practical strategy to mitigate radiation-related complications in clinical settings.

Gossypiboma must be considered when fever, unilateral swelling, tenderness, or unhealed oral wound is sustained despite an antibiotics therapy and a drainage procedure after a mandible angle surgery. In that case, a computed tomographic scan can be recommended as an effective method for detection of gossypiboma.
