Enhancing Philtrum Morphology Using Fat Grafting Combined with Percutaneous Rigottomy in Repaired Unilateral Cleft Lip.

Background: Improving the philtrum morphology of patients with a secondary cleft lip deformity has been a challenge in cleft care. Combining fat grafting with percutaneous rigottomy has been advocated for treatment of volumetric deficiency associated with a scarred recipient site. This study assessed the outcome of synchronous fat grafting and rigottomy for improvement of cleft philtrum morphology.

Comparison of Facial Growth between Two Nasoalveolar Molding Techniques in Patients with Unilateral Complete Cleft Lip.

Background: Nasoalveolar molding (NAM) has become standard treatment in the authors' craniofacial center. There are two types of presurgical NAM: the Grayson and Figueroa techniques. The Grayson method involves active alveolar molding, and the Figueroa method involves passive alveolar molding.

Refining Orthognathic Surgery Results by Synchronous Cheek Fat Compartment Augmentation with Fat Grafting in Adult Females with Class III Skeletal Profiles.

Summary: Patients with maxillomandibular disharmony may present with a flat to concave midface. The effects of orthognathic surgery concomitant with midface fat grafting on facial appearance and midface volumetric and positional change have not formally been assessed to date. The authors' approach for synchronous orthognathic surgery and fat grafting is described and evaluated.

Botulinum Toxin to Improve Lower Blepharoplasty Scar: A Double-Blinded, Randomized, Vehicle-Controlled Clinical Trial.

Background: Lower blepharoplasty is a common cosmetic operation that relies on minimal postoperative scarring, but Asian patients are at higher risk than Caucasians for hypertrophic and/or widened scars. Botulinum toxin type A (BTX) injections are widely employed to alleviate dynamic facial rhytids and also can improve scar quality by reducing scar tension. The authors assessed whether simultaneous transcutaneous lower blepharoplasty and BTX injections could improve subciliary scar quality.

Total HLA Class I Antigen Loss with the Downregulation of Antigen-Processing Machinery Components in Two Newly Established Sarcomatoid Hepatocellular Carcinoma Cell Lines.

Limited information is currently available concerning HLA class I antigen abnormalities in sarcomatoid hepatocellular carcinoma (sHCC). Here, we have analyzed the growth characteristics and HLA class I antigen status of four sHCC cell lines (sHCC29, sHCC63, sHCC74, and SAR-HCV); the first three were newly established in this study. Among the four, sHCC29 showed the highest growth rate and tumorigenicity in NOD-SCID mice.

Masseter Muscle Volume Changes Evaluated by 3-Dimensional Computed Tomography After Repeated Botulinum Toxin A Injections in Patients With Square Facial Morphology.

Introduction: Botulinum neurotoxin A (BoNT-A) is a minimally invasive and technically straightforward treatment of masseter muscle (MM) volume reduction and facial contouring, but the literature on its long-term effect on MM volume remains unclear.

Early administration of empagliflozin preserved heart function in cardiorenal syndrome in rat.

This study tested the hypothesis that early administration of empagliflozin (Empa), an inhibitor of glucose recycling in renal tubules, could preserve heart function in cardiorenal syndrome (CRS) in rat. Chronic kidney disease (CKD) was caused by 5/6 subtotal nephrectomy and dilated cardiomyopathy (DCM) by doxorubicin (DOX) treatment.

Combined Therapy with SS31 and Mitochondria Mitigates Myocardial Ischemia-Reperfusion Injury in Rats.

Myocardial ischemia-reperfusion (IR) injury contributes to adverse cardiac outcomes after myocardial ischemia, cardiac surgery, or circulatory arrest. In this study, we evaluated the ability of combined SS31-mitochondria (Mito) therapy to protect heart cells from myocardial IR injury. Adult male SD rats ( = 8/each group) were randomized: group 1 (sham-operated control), group 2 (IR, 30-min ischemia/72 h reperfusion), group 3 (IR-SS31 (2 mg intra-peritoneal injection at 30 min/24 h/48 h after IR)), group 4 (IR-mitochondria (2 mg/derived from donor liver/intra-venous administration/30 min after IR procedure)), and group 5 (IR-SS31-mitochondria).

Clinical evaluation of silicone gel in the treatment of cleft lip scars.

Upper lip scars are at risk of hypertrophy. Our center therefore uses microporous tape and silicone sheeting for postoperative scar care following cleft lip repair. However, some babies have previously ingested their silicone sheeting, which has the potential for respiratory compromise or gastrointestinal obstruction.
