Interference of silicone breast implants on bioimpedance measurement of body fat.

BACKGROUND: No study targeting the impact of silicone breast implants on body composition measured by bioimpedance analysis was identified. OBJECTIVE: Aiming to clarify this question a prospective clinical study was designed. METHODS: Adult candidates were submitted to conventional analysis at baseline and two months after the surgical intervention. In addition, unwrapped prostheses were positioned in the axillary cavity before operation and bioimpedance was measured, both with and without application of ultrasound gel for improved conductivity (sham implantation). RESULTS: Patients (N = 20) were young and healthy (26.8 ± 3.6 years old, BMI 22.1 ± 3.7 kg/m(2)). In comparison with preoperative results, sham procedures pointed out increased body fat and body resistance (13.2 ± 5.6 vs 13.6 ± 5.4 kg, P = 0.017 and 523 ± 54 vs 569 ± 53 Ω, P = 0.003, respectively). Two-month follow-up confirmed the same pattern after surgical intervention, with minor discrepancies (13.2 ± 5.6 vs 13.8 ± 5.7 kg, P = 0.011 and 523 ± 54 vs 549 ± 62 Ω, P = 0.032, respectively). BMI remained stable and did not correlate with bioimpedance changes. CONCLUSIONS: Silicone was recognized as adipose tissue. Difference in total body fat (approximately 600 g) was consistent with used amount.

Improved double-fuse technique for post-bariatric brachioplasty.

OBJECTIVE: To evaluate the use of modified brachioplasty, investigating in late postoperative complications and satisfaction with the outcome, in women previously submitted to bariatric surgery. METHODS: The population (N = 18, age 49.2 ± 11.3 years), which had undergone brachioplasty 25.2 ± 11.9 months after the bariatric procedure, was contacted after 31.7 ± 38.8 additional months. Surgical complications and satisfaction with the operation were estimated by interviews, including a questionnaire designed for this purpose. RESULTS: pre-bariatric body mass index (BMI) was 57.1 ± 11.1 kg / m(2), being 28.3 ± 6.0 kg/m(2) before the brachioplasty, without significant changes thereafter. Three minor surgical complications were recorded (3 / 18, 16.7%), namely, temporary paresthesia, seroma and small imperfection of the scar. The satisfaction rate was approximately 90%, with the three most rewarding results for the patients being the ease of dressing (P = 0.01), decreased weight of the arm (P = 0.03) and absence of edema (P = 0.04). There was a negative correlation between severe weight loss and degree of satisfaction, however, no patients regretted the procedure. CONCLUSION: the modified brachioplasty was successful in cases with severe brachial ptosis with possible extension to the chest. The study confirmed functional and aesthetic benefits, and thanks to the technique applied, most of the complications and disappointments could be avoided.

Técnica aprimorada de duplo fuso para braquioplastia pós-bariátrica / Improved double-fuse technique for post-bariatric brachioplasty

OBJETIVO: Avaliar o emprego da braquioplastia modificada investigando no pós-operatório tardio as complicações e a satisfação com o resultado, em mulheres previamente submetidas à cirurgia bariátrica. MÉTODOS: A população ((N=18, idade 49,2 ± 11,3 anos), que havia sido submetida à braquiopastia 25,2 ± 11,9 meses após o procedimento bariátrico, foi contactada após 31,7 ± 38,8 meses adicionais. As complicações cirúrgicas e a satisfação com a operação foram estimadas através de entrevista, incluindo-se um questionário concebido para esta finalidade. RESULTADOS: O índice de massa corporal (IMC) pré-bariátrico era de 57,1 ± 11,1kg/m², situando-se antes da braquioplastia em 28,3 ± 6,0kg/m², sem alterações significativas subsequentes. Três complicações cirúrgicas menores foram registradas (3/18, 16,7 por cento), a saber: parestesia temporária, seroma e pequena imperfeição da cicatriz. A taxa de satisfação foi de aproximadamente 90 por cento, sendo os três resultados mais gratificantes para as pacientes a facilidade de se vestir (P=0,01), a diminuição do peso do braço (P=0,03) e a ausência de edema (P=0,04). Ocorreu correlação negativa entre perda de peso acentuada e grau de satisfação, todavia, nenhuma doente arrependeu-se da intervenção cirúrgica. CONCLUSÃO: A braquioplastia modificada foi bem sucedida em casos de ptose braquial grave com possível extensão para o tórax. Confirmaram-se benefícios funcionais e estéticos, e, graças à técnica adotada, a maioria das complicações e desapontamentos pôde ser evitada.

Systemic inflammatory reaction after silicone breast implant.

BACKGROUND: Systemic inflammation after augmentation mammaplasty with modern silicone implants is not currently recognized. In a prospective controlled study, C-reactive protein and other variables were monitored, aiming to test this hypothesis in a young cohort of patients. METHODS: Females (18-30 years old, BMI = 18.5-30 kg/m(2), N = 52) were consecutively recruited for breast implant (n = 24, Group I) and for abdominal liposuction (n = 28, Group II/Controls). Patients were interviewed at baseline and followed until 6 months after operation. Variables included demographic and clinical information, surgical outcome, inflammatory markers and autoantibodies. RESULTS: Operations were well tolerated, without surgical or infectious complications. Mean prosthesis size was 258 ± 21 ml (range = 220-280) and mean aspirate of liposuction was 1972 ± 499 ml (range = 1200-3000). Preoperative, 2-month, and 6-month C-reactive protein concentrations for breast implant patients were 1.3 ± 1.2, 4.8 ± 3.0, and 4.3 ± 6.4 mg/l and for liposuction 3.5 ± 2.7, 3.5 ± 2.1, and 2.2 ± 2.2 mg/l, respectively. Change at 2 months was significant (p = 0.001). Autoantibody investigation failed to reveal remarkable aberrations, except for anticardiolipin elevation, which was nearly symmetrical in the two groups. CONCLUSION: C-reactive protein levels increased after operation and correlated with proinflammatory and procoagulatory indices. A mild increase in anticardiolipin IgM occurred but differences between populations were lacking. Despite excellent cosmetic outcomes and lack of complications, acute phase reaction could signal ongoing immunogenicity of silicone and long-term monitoring is recommended.
