Initial Experience of Face Augmentation Using Fat Graft-Platlet Rich Plasma Mix

Plastic surgeons accustomed to use autologous fat grafs for augmentation of soft tissues in the last two decades. The main drawback of fat grafting is unpredictable graft resorption. Several studies have searched for new ways of increasing the viability of the transplanted tissue to overcome this disadvantage. The most recent and promising approach is to mix the fat graft with Platelet-Rich Plasma (PRP) before transplantation. The purpose of this article is to present the initial experience using the autologous fat injection with platlet rich plasma as a method for fascial augmentation.

Surgical Treatment of Gynaecomastia: A Prospective Study in 75 Patients

Introduction: Gynaecomastia is a benign enlargement of male breast;many techniques have been described for management but none have gained universal acceptance. We discuss the outcomes of the surgical management of gynaecomastia and assess the morbidity and complication rates associated with the procedure to determine whether certain surgical techniques produce better outcomes. Materials and Methods: 75 patients with gynaecomastia were operated in our hospital during the period from Jan. 2009 to Jan. 2015. Results: A total of 140 breasts were operated on during the study period. Patients underwent either liposuction alone (20 breasts), excision alone (70 breasts), both excision and liposuction (36 breast) or skin reduction procedure (14 breasts). 19 operated breasts (13.4%) experienced some form of complications. Minor complications included seroma (4 patients), superficial wound dehiscence (3 patients) and two patients developed haematomas requiring evacuation in theatre. Unsatisfactory cosmotic result was present in 10 breasts and surgical revision was done in 5 breasts. Simon grade 111 breasts experienced the highest complication rate. Conclusion: The study has found that moderate sized gynaecomastia whether true or pseudo gynaecomastia with mild to moderate breast redundancy can be managed easily and effectively by liposuction alone or combined with glandular resection while the conventional infraareolar subcutaneous mastectomy still gives satisfactory results and with no need to remove extra skin. On the other hand, large gynaecomastia with severe breast redundancy can be treated effectively by the inferior pedicle technique without vertical scar.

Management of Post-Circumcision Trapped Penis with Glanular Amputation

A phenomenon known as trapped penis has numerous origins, including injudicious circumcision. Materials and Methods: Surgery for trapped penis with glanular amputation was performed for 5 children. The surgical policy in these cases included complete penile degloving, excising the scarring due to circumcission, fixing the penile skin at the penopubic and penoscrotal angles and reconstructing the penile skin with full thickness skin graft. Results: Improvement was noted in all cases. Conclusion: Surgery for hidden penis using full thickness skin graft achieves very satisfactory aesthetic and functional improvement.

In vitro and in vivo evaluation of cubosomes containing 5-fluorouracil for liver targeting

The objective of this study was to prepare cubosomal nanoparticles containing a hydrophilic anticancer drug 5-fluorouracil(5-FU) for liver targeting. Cubosomal dispersions were prepared by disrupting a cubic gel phase of monoolein and water in the presence of Poloxamer 407 as a stabilizer.Cubosomes loaded with 5-FU were characterized in vitro and in vivo. In vitro, 5-FU-loaded cubosomes entrapped 31.21% drug and revealed nanometer-sized particles with a narrow particle size distribution. In vitro 5-FU release from cubosomes exhibited a phase of rapid release of about half of the entrapped drug during the first hour, followed by a relatively slower drug release as compared to 5-FU solution. In vivo biodistribution experiments indicated that the cubosomal formulation significantly(Po 0.05) increased5-FU liver concentration, a value approximately 5-fold greater than that observed with a 5-FU solution.However, serum serological results and histopathological findings revealed greater hepatocellular damage in rats treated with cubosomal formulation. These results demonstrate the successful development of cubosomal nanoparticles containing 5-FU for liver targeting. However, further studies are required to evaluate hepatotoxicity and in vivo antitumor activity of lower doses of 5-FU cubosomal formulation in treatment of liver cancer.

Comparison of drug release from liquid crystalline monoolein dispersions and solid lipid nanoparticles using a flow cytometric technique

Colloidal lipid particles such as solid lipid nanoparticles and liquid crystalline nanoparticles have great opportunities as drug carriers especially for lipophilic drugs intended for intravenous administration. In order to evaluate drug release from these nanoparticles and determine their behavior after administration, emulsion droplets were used as a lipophilic compartment to which the transfer of a model drug was measured. The detection of the model drug transferred from monoolein cubic particles and trimyristin solid lipid nanoparticles into emulsion droplets was performed using a flow cytometric technique. A higher rate and amount of porphyrin transfer from the solid lipid nanoparticles compared to the monoolein cubic particles was observed. This difference might be attributed to the formation of a highly ordered particle which leads to the expulsion of drug to the surface of the crystalline particle.Furthermore, the sponge-like structure of the monoolein cubic particles decreases the rate and amount of drug transferred. In conclusion, the flow cytometric technique is a suitable technique to study drug transfer from these carriers to large lipophilic acceptors. Monoolein cubic particles with their unique structure can be used successfully as a drug carrier with slow drug release compared with trimyristin nanoparticles.
