RESUMO Introdução: A busca de um substituto anatômico para a mama, para fins de correção de problemas estéticos, tem longa história de insucessos até a chegada do silicone. Desde o início de seu uso, na década de 1960, muitas complicações surgiram, como infecção, rejeição, rotura, além do extravasamento de silicone. Não encontramos na literatura, porém, relato algum sobre a passagem de materiais do organismo humano para o interior de implantes. O objetivo é a identificação por espectrofotometria de infravermelho (FTIR) e análise clínica, relatando a passagem de substâncias orgânicas para o interior de implantes mamários sem que os mesmos apresentem violação qualquer de sua cápsula. Método: Foram analisados 1500 pares de implantes mamários, removidos cirurgicamente no período de 1998 a 2018. Destes, seis foram encaminhados incluídos no estudo. Resultados: Foram analisados três materiais apresentando alterações macroscópicas em seu interior, sem que houvesse violação da cápsula. Uma segunda amostra foi realizada em implante semelhante, porém sem uso. O terceiro material foi uma amostra de tecido gorduroso mamário removido da própria paciente durante o ato cirúrgico. Foram encontrados materiais compatíveis com gordura, proteína animal e hemoglobina no interior do implante. Conclusões: A alteração evidenciada no material do interior dos dois implantes nos indica a ocorrência de passagem de materiais orgânicos através de cápsula intacta. ABSTRACT Introduction: The search for an anatomical substitute for the breast, for the purpose of correcting aesthetic problems has a long history of failure until the arrival of silicone. Since the beginning of its use, in the 1960s, many complications have appeared, such as infection, rejection, rupture, in addition to silicone leakage. We did not find in the literature, however, any report on the passage of materials from the human organism to the interior of implants. The objective is to identification by infrared spectrophotometry (FTIR) and clinical analysis, reporting the passage of organic substances into breast implants without any violation of their capsule. Methods: 1500 pairs of breast implants were analyzed, surgically removed from 1998 to 2018. Of which six were included in the study. Results: Three materials were analyzed showing macroscopic changes in their interior, without violating the capsule. A second sample was performed on a similar implant, but without use. The third material was a sample of fatty breast tissue removed from the patient during the surgery. Materials compatible with fat, animal protein and hemoglobin were found inside the implant. Conclusions: The change evidenced in the material inside the two implants indicates the occurrence of the passage of organic materials through an intact capsule.

The treatment of breast ptosis using mastopexy associated with the inclusion of a silicone prosthesis in a single surgical procedure is a challenge for surgeons. The aim of this study is to describe the 15-year experience with the placement of silicone breast implants in double, subfascial and submuscular space, in the treatment of patients with breast ptosis, and to analyze the aesthetic results of patients who underwent such surgeries. During the 15-year period, between 2005 and 2020, 640 mastopexies were performed with the inclusion of silicone breast implants in double space, with high-profile round polyurethane prostheses whose volumes ranged from 135 to 435 ml, in patients with grade 2 and 3 breast ptosis. The age of the patients ranged from 18 to 55 years and the average age was 34 years. The postoperative follow-up time was 18 months. 400 patients (62.5%) had grade II ptosis, whereas 240 of them (37.5%) had grade III ptosis. The main complications were: 19 cases (3%) of residual sagging skin, 19 cases (3%) of unsightly scars, 12 cases (2%) of partial areola necrosis. There was no case of infection or seroma. There were 330 primary surgeries (52%) and 310 secondary surgeries (48%). After 15 years of performing mastopexy with prosthesis in double space, both in primary and secondary surgeries, it can be concluded that the technique reached its maturity providing good long-term results with the maintenance of the projection of the upper pole of the breast and low recurrence of ptosis in the lower pole and low rate of complications.

Surgery for abdominal wall has showed significant progress in recent decades, related to reduce the area for undermining, as well as on the size of the final scars. We have observed cases of minor localized adiposities with reduced muscular diastases but with significant changes of the umbilicus which there is no indication for liposuction, traditional abdominoplasty, or lipoabdominoplasty.

Abdominoplasty surgery has spread universally, as both an aesthetic and a reconstructive procedure, and new techniques are appearing with the goal of minimizing ischemic complications of the flap and bettering body contour. The purpose of this article is to demonstrate that an abdominoplasty technique with limited undermining and preservation of the flap perforator vessels makes it possible to reduce the complication rate attributable to flap necrosis and seroma in abdominoplasty. Doppler flowmetry color study of the abdominal wall was performed before the surgical procedure and on postoperative day 15 after lipoabdominoplasty for a series of 20 patients to evaluate the blood supply of the abdominal wall. This study confirmed the preservation of perforator arteries in the periumbilicus area and right upper quadrant after abdominoplasty with liposuction and reduced undermining.

According to the authors, advantages of short scar face lift associated with lateral SMASectomy and vertical vector closure include a lower rate of hematomas and facial nerve injury, less skin tailoring, no retroauricular skin slough, and reduced operative time. Results in 96 patients demonstrate good neck redefinition, excellent facial contour, and elevated midface. (Aesthetic Surg J 2003;23:198-201.)

Abdominal compartment syndrome is directly related to an increase in intraabdominal pressure (IAP), which can lead in severe cases to serious clinical consequences. Routine measurement of IAP in specific cases has been advocated by some surgical specialties. However, few studies in plastic surgery have focused on the use of IAP. The authors review the literature and describe a method of IAP analysis used for 12 patients who underwent abdominoplasty.

INTRODUÇÃO: A cicatrização é processo complexo, com diferentes fases. Embora exista grande variedade de plantas medicinais poucas têm sido investigadas com intenção de melhorar a cicatrização de órgãos e tecidos, dentre elas, a Orbignya phalerata (babaçu). OBJETIVO: Analisar comparativamente as alterações tensiométricas e histológicas na cicatrização de anastomoses colônicas proporcionadas pelo uso do extrato aquoso do mesocarpo do babaçu (Orbignya phalerata). METODOS: Utilizaram-se 40 ratos Wistar, machos, separados em dois grupos de vinte, denominados grupos controle e experimento, Os ratos de cada grupo foram divididos em dois sub-grupos de 10 animais cada e avaliados no terceiro e sétimo dia de pós-operatório. Realizaram-se colotomia e colorrafia em plano único. Os animais do grupo controle receberam no ato operatório dose única de solução salina isotônica em dose e via de administração semelhantes ao grupo experimento e os do grupo experimento receberam extrato aquoso de babaçu em dose de 50 mg/kg/peso, concentração de 25 mg/ml por via intraperitoneal. Foram analisados os seguintes parâmetros: a) avaliação macroscópica da parede e cavidade abdominal; b) avaliação tensiométrica da anastomose (pressão e ruptura); c) características histológicas da anastomose. RESULTADOS: O exame macroscópico evidenciou a presença de aderências em todos os animais, sendo estatisticamente maior no grupo experimento de três dias quando comparados com o grupo controle. Nos animais do grupo de sete dias não houve diferença. Não houve ocorrência de deiscência de anastomose, fístulas, abscessos e/ou hemorragia. Com relação à tensiometria, constatou-se que a média de ruptura dos grupos controle e experimento tanto para os animais do grupo de três dias (25,4 mmHg - 14,8 mmHg) quanto para os de sete dias (183 mmHg - 175 mmHg), foram iguais, não ocorrendo diferença estatisticamente significante. A análise histológica dos animais do grupo de três dias mostrou diferença estatisticamente significante no grupo experimento em relação ao controle na variável mononuclear, enquanto que, no sétimo dia, houve diferença estatisticamente significante favorável ao grupo experimento em todas as variáveis quando comparadas com o de controle. CONCLUSÃO: Ocorreu efeito favorável no uso do extrato aquoso do mesocarpo do babaçu no processo de cicatrização da anastomose colônica, não havendo diferença significante na avaliação tensiométrica entre os grupos controle e experimento.

The authors report two cases of traumatic chylothorax. They were caused by gunshot wounds producing thorax transfixing injuries and lhe chilothorax was subsequently diagnosed during lhe thoracic drainage follow-up, a chilous colar was noticed in lhe drainage output. This was confirmed with a Sudam 111 stain. Both cases were treated conservatively with Total Parenteral Nutrition according to the current literature. One of the cases, in its evolution, required surgical treatment due to a persistent high output fistulae.

In de past 50 years, maternal mortality rates have declined, in contrast, the number of deaths due to injury during pregnancy is on the rise. The authors report a case of 24° week pregnant woman victim of penetrating abdominal trauma by gunshot who sustained a grade I11 transfixing injury of the uterine fundus. Treatment was conservative regarding the fetus. Hysteroraphia of the injuries was executed with closure of both penetrating orifices. Obstetrical-gynecological evaluation and echogram documented letal viability in the post-operative period. Post-operative follow-up was performed with periodical echograms up to delivery on the ninth month. Clinical findings, treatment and follow-up will be discussed.
