Ultra HD Liposuction: Enhancing Abdominal Etching Using Ultrasound-Guided Rectus Abdominis Fat Transfer (UGRAFT).

High-definition (HD) liposuction has allowed surgeons to sculpt the abdomen, enhancing abdominal etching. To create a more athletic abdomen, fat grafting has been used subcutaneously, and rectus abdominis fat grafting has been performed in patients undergoing lipoabdominoplasty. With the objective of increasing muscle volume to obtain a natural-looking abdomen in patients who are not suitable for abdominoplasty, we propose the use of ultrasound-guided rectus abdominis fat grafting (UGRAFT) in association with HD liposuction. PATIENTS: A prospective study with 10 consecutive patients undergoing UGRAFT was conducted. After HD liposuction, UGRAFT was performed from an incision in the umbilical region, using a blunt 2.5-mm cannula assisted by ultrasound. Fat injection was done closer to the anterior rectus sheath in the lower and middle muscle bellies. RESULTS: UGRAFT was performed in 10 patients. The mean age was 34.8 years (range, 24-51 years). The mean body mass index was 23.83 kg/m2 (range, 20.58-28.39 kg/m2). The mean volume of fat injected per "pack" was 34 cm3 (range, 20-40 cm3). UGRAFT added a mean time of 20 minutes (range, 15-30 minutes) to HD liposuction. Comparing the rectus abdominis muscle thickness pre-UGRAFT and post-UGRAFT, average muscle thickness increase was 5.1 mm (55.7% ± 37%), with P < 0.0001. CONCLUSION: UGRAFT showed to be helpful for obtaining muscle expansion and a more natural abdominal contour, avoiding that unnatural appearance that HD liposuction may provide in patients who gain weight or have skin laxity.

Galactocele medicamentosa pós-mamoplastia de aumento: relato de caso e revisão da literatura / Galactocele due to drugs prescribed after augmentation mammoplasty: a case report and literature review

A mamoplastia de aumento é um procedimento cirúrgico muito comum e seguro na cirurgia plástica, mas o mesmo não está isento de complicações. A galactocele após mamoplastia de aumento é raramente descrita na literatura. Este relato de caso refere-se a uma paciente de 34 anos de idade, que fazia uso de sulpirida há 2 anos e 4 meses e desenvolveu galactocele cerca de 100 dias após mamoplastia de aumento. O diagnóstico deve ser suspeitado quando se observar uma mama aumentada de volume, associada a calor local, dor ou desconforto mamário no pós-operatório. Acredita-se que a melhor conduta seja a drenagem cirúrgica, a fim de confirmar o diagnóstico de galactocele e excluir a presença de abscesso mamário.

Augmentation mammaplasty is a common and safe plastic surgery procedure, but it is not free from complications. Galactocele after augmentation mammaplasty is rarely described in the literature. We discuss the case of a 34-year-old woman who had been taking sulpiride for 2 years and 4 months and developed galactocele approximately 100 days after augmentation mammaplasty. However, diagnosis should be suspected if breast size increases and it is associated with postoperative local heat, pain or breast discomfort. We believe that the surgeon must surgically drain galactocele to confirm diagnosis, especially to exclude the presence of breast abscess.

Ion release from a composite resin after exposure to different 10% carbamide peroxide bleaching agents.

OBJECTIVE: This in vitro study evaluated the influence of two 10% carbamide peroxide bleaching agents - a commercial product (Opalescence PF; Ultradent Products, Inc.) and a bleaching agent prepared in a compounding pharmacy - on the chemical degradation of a light-activated composite resin by determining its release of ions before and after exposure to the agents. MATERIAL AND METHODS: Thirty composite resin (Filtek Z250; 3M/ESPE) samples were divided into three groups: group I (exposed to Opalescence PF commercial bleaching agent), group II (exposed to a compounded bleaching agent) and group III (control - Milli-Q water). After 14 days of exposure, with a protocol of 8 h of daily exposure to the bleaching agents and 16 h of immersion in Milli-Q water, the analysis of ion release was carried out using a HP 8453 spectrophotometer. The values were analyzed statistically by ANOVA, Tukey's test and the paired t-tests. The significance level was set at 5%. RESULTS: After 14 days of the experiment, statistically significant difference was found between group II and groups I and III, with greater ion release from the composite resin in group II. CONCLUSIONS: The compounded bleaching agent had a more aggressive effect on the composite resin after 14 days of exposure than the commercial product and the control (no bleaching).
