Clinical Evaluation of Unsintered Hydroxyapatite Particles/Poly L-Lactide Composite Device in Craniofacial Surgery.

A total of 47 patients who underwent the craniofacial implantation of unsintered hydroxyapatite particles and a poly-L-lactide device were evaluated for clinical local findings and computed tomography (CT) images after about 6 months. Long-term follow-up of 3 patients was done from 5 to 11 years. The patients underwent CT imaging pre- and postoperatively, while local clinical examination was done upon follow-up.

Use of dermal fat grafts for treating anetoderma with lipoatrophy following involution of hemangiomas.

Infantile hemangioma (IH) is a benign vascular tumor that gradually involutes over several years. Rapidly involuting congenital hemangioma (RICH) is the relatively rare congenital vascular tumor that is fully grown at birth and does not undergo postnatal growth and involutes during the first year. However, after involution of both IH and RICH, some have severe sequelae, such as redundant skin or conspicuous scarring, requiring additional treatment.

Deprotonative Silylation of Aromatic C-H Bonds Mediated by a Combination of Trifluoromethyltrialkylsilane and Fluoride.

A method for the deprotonative silylation of aromatic C-H bonds has been developed using trifluoromethyltrimethylsilane (CFSiMe, Ruppert-Prakash reagent) and a catalytic amount of fluoride. In this reaction, CFSiMe is considered to act as a base and a silicon electrophile. This process is highly tolerant to various functional groups on heteroarenes and benzenes.
