Milky secretion after late breast reconstruction with latissimus dorsi musculocutaneous flap with implant / Produção de secreção leitosa após reconstrução mamária tardia com retalho musculocutâneo de latíssimo do dorso com implante

We present a rare case of a 28-year-old patient with invasive ductal carcinoma who underwent neoadjuvant chemotherapy, modified radical mastectomy, radiotherapy, and late breast reconstruction with latissimus dorsi flap associated with the implant. One year later, she underwent reconstruction of the nipple-areola complex over the cutaneous island of the latissimus dorsi flap with a total skin graft from the thigh and graft from the caudal portion of the contralateral papilla. She became pregnant six months after the reconstruction of the nipple-areola complex and, unexpectedly, presented milk production by the reconstructed breast.

Apresentamos um caso raro de uma paciente de 28 anos com carcinoma ductal invasivo submetida a quimioterapia neoadjuvante, mastectomia radical modificada, radioterapia e reconstrução mamária tardia com retalho de latíssimo do dorso associado a implante. Um ano depois, foi submetida a reconstrução do complexo areolopapilar sobre a ilha cutânea do retalho do grande dorsal com enxerto de pele total da coxa e enxerto da porção caudal da papila contralateral. Ela engravidou seis meses após a reconstrução do complexo areolopapilar e, inesperadamente, apresentou produção de leite pela mama reconstruída.

Quality of breast reconstruction service at a university hospital as assessed by the patients.

PURPOSE: To evaluate the quality of breast reconstruction service at a university hospital, as assessed by the patients. METHODS: This cross-sectional study enrolled adult women who underwent immediate or delayed breast reconstruction by any technique performed at a university hospital between 1 and 24 months before the assessment. The Brazilian version of the Health Service Quality Scale (HSQS) was self-applied to the participants. The HSQS produces percentage scores, which are expressed in values ranging from 0 to 10 for each domain of the scale, and into an overall percentage quality score. The management team was asked to establish a minimum satisfactory score for the breast reconstruction service. RESULTS: Ninety patients were included. The management team considered 8.00 the minimum satisfactory score for the service. The overall percentage score was 93.3%. Only one domain, 'Support,' had an average score lower than that considered satisfactory (7.22 ± 3.0); while the others had higher scores. The domain that scored highest was 'Qualification' (9.94 ± 0.3), followed by 'Result' (9.86 ± 0.4). There was a positive correlation between 'type of oncologic surgery' and 'intentions of loyalty to the service' (ρ = 0.272; p = 0.009) and a negative correlation between 'education' and 'quality of the environment' (ρ = -0.218; p = 0.039). The higher the patient's level of education, the higher the score attributed to 'relationship' (ρ = 0.261; p = 0.013) and the lower the score of 'aesthetics and functionality' (ρ = -0.237; p = 0.024). CONCLUSIONS: The quality of the breast reconstruction service was considered satisfactory, but there is a demand for structural improvements, better interpersonal relationships, and a stronger support network for patients.

Patient-Reported Outcomes after Subpectoral Breast Augmentation with Microtextured or Macrotextured Implants Using the BREAST-Q.

Background Breast augmentation with implants is the most commonly performed cosmetic plastic surgery in Brazil and worldwide. The aim of this study was to assess patient satisfaction and quality of life following subpectoral breast augmentation with either microtextured or macrotextured implants, using the BREAST-Q. Methods A prospective study was conducted with 40 women with hypomastia undergoing subpectoral breast augmentation. The patients were randomly allocated to two groups to receive either microtextured or macrotextured breast implants. All participants were assessed preoperatively (baseline) and after 2 and 4 months of surgery for quality of life and patient satisfaction with the surgical results, using the BREAST-Q augmentation module, a patient-reported outcome measure. Results The patients had a mean age of 28.9 ± 6.45 years. The microtextured ( n = 20) and macrotextured ( n = 20) groups were homogeneous for sex, age, education level, marital status, and number of children ( p > 0.05). Both groups showed significant improvement in satisfaction with breasts ( p < 0.001), psychosocial well-being ( p < 0.001), and sexual well-being ( p < 0.001) at the 2- and 4-month follow-up visits compared with baseline. The observed improvements were associated with high effect size values of 5.09, 3.44, and 3.90, respectively. In contrast, significant decreases from baseline in physical well-being scores ( p = 0.001) were found 2 and 4 weeks after surgery in both groups. Conclusion Subpectoral breast augmentation with either microtextured or macrotextured breast implants improved satisfaction with breasts and quality of life in patients with hypomastia.

Translation and cross-cultural adaptation of the Brazilian version of BREAST-Q©: breast reconstruction expectations module.

OBJECTIVE: This study aimed to translate the BREAST-Q© - Breast Reconstruction Expectations Module (preoperative) 2.0 into Portuguese and adapt it to the Brazilian cultural context. METHODS: Authorization for translation and cross-cultural adaptation of the questionnaire was obtained from the holders of the instrument's distribution rights. The questionnaire was translated and retro-translated. For cultural adaptation, the instrument was applied to 40 patients who had breast reconstruction surgery scheduled. Cronbach's alpha was used to assess the internal consistency. RESULTS: The mean age of the patients was 53.5 years, and the majority (72.5%) was undergoing reconstruction with implants. Good and excellent internal consistencies were observed for the Coping and Appearance expectations scales (Cronbach's alpha values of 0.878 and 0.909, respectively). For the Pain scale, the internal consistency was moderate (0.738), and it was acceptable (0.587) for the Medical team. CONCLUSION: The BREAST-Q© - Breast Reconstruction Expectations Module (preoperative) 2.0 was successfully translated and adapted to the Brazilian context.

Antibiotic Prophylaxis in Reduction Mammaplasty: A National Survey.

BACKGROUND: Although there is limited evidence for regulating the use of prophylactic antibiotics in reduction mammaplasty, many plastic surgeons prescribe them, even in the postoperative period. This study aimed to conduct a national survey to investigate the antibiotic prophylaxis protocols followed by Brazilian plastic surgeons in reduction mammaplasty. METHODS: An anonymous survey comprising 19 questions was sent to all 4864 active members of the Brazilian Society of Plastic Surgery (SBCP). The surgeons electronically received the invitation to participate in the survey and the link to fill out the electronic form. RESULTS: In total, 859 surgeons (17.7%) responded. Most respondents (77.8%) were men and aged 35-55 years (61.5%); 58.6% of them had 10-29 years of specialty training. Only a minor proportion of the respondents (0.5%) reported not prescribing antibiotics at any time (95% confidence interval [CI]: 0.0-0.9), 9.9% (95% CI: 7.9-11.9) prescribed them only preoperatively, and 14.6% (95% CI: 12.2-16.9) prescribed continued antibiotic use for 24 h. The majority of the respondents (75.1%; 95% CI: 72.1-77.9) prescribed antibiotics for additional days after discharge. There were significant associations between antibiotic prescription and the surgeons' age group (p = 0.015), time since graduation (p < 0.001), experience in the specialty practice (p = 0.003), SBCP membership (p < 0.001), and surgical site infection rates (p = 0.011). CONCLUSION: Most responding plastic surgeons affirmed that they prescribed prophylactic antibiotics for more than 24 h in reduction mammaplasty cases.

Publications, by different surgical specialties, on patient-reported outcomes of oncoplastic surgery.

OBJECTIVE: This study aimed to compare the publications authored by plastic surgeons with those from other specialties' surgeons on patient-reported outcomes of oncoplastic surgery. METHODS: A review was carried out on the Medline database, emcompassing five years (2015-2020). Studies about partial breast reconstruction after conservative treatment, immediate or delayed, by any technique, which presented patient-reported outcomes, were included. RESULTS: We found 292 articles, from which 142 met the eligibility criteria. Publications were stratified into groups 1 (plastic surgeons) and 2 (other surgical specialties), and also into groups A (only plastic surgeons), B (only other specialties) and C (both), and compared statistically. Most publications (60.6%) were attributed to specialties other than plastic surgery. Nineteen percent had only plastic surgeons as authors, 50% only other specialties' surgeons, and 31% had both. There was no difference between groups regarding the impact factor of the journals in any of the stratifications, and the majority was published in journals with impact factor ≤2. CONCLUSION: In the last years, surgeons from specialties other than plastic surgery published more about the results of the oncoplastic surgery reported by the patients. There was no statistical difference between the groups regarding the impact factor of the journals.

Mamoplastia: passos para uma cirurgia segura. Evidências da literatura / Mammoplasty: steps for safe surgery. Evidence from literature

RESUMO Introdução: A mamoplastia é uma das cirurgias mais realizadas pelos cirurgiões plásticos. Como todo procedimento, não é isenta de riscos ou complicações. Objetivos: Discutir questões controversas e intercorrências em cirurgia mamária e principais tratamentos. Métodos: Participaram da discussão quatro membros titulares da SBCP com ampla experiência em cirurgia plástica mamária, além do regente do capítulo de mamoplastias. Foram avaliados fatores que apresentavam maior controvérsia em mamoplastias: utilização de antibióticos; infiltração pré-operatória; associação da mamoplastia com implantes mamários; grandes ptoses mamárias; mamoplastia masculinizadora; retalhos para ascensão do complexo areolopapilar (CAP); utilização de drenos; curativos em mamoplastias e enxerto de gordura. Resultados: A literatura e discussão entre especialistas gerou as observações: há evidencias robustas da efetividade no uso de antibióticos perioperatório de mamoplastias redutoras, mas não há evidências de benefícios em se manter o uso por mais de 24 horas; a infiltração pré- operatória com soluções vasoconstritoras não reduz a incidência de hematoma; em mamoplastia associada a implantes não houve consenso sobre a melhor técnica, plano ou textura do implante; não houve consenso sobre a melhor técnica na ascensão do CAP em grandes ptoses, se enxertos ou retalhos; a mamoplastia masculinizadora não apresenta complicações diversas das encontradas na literatura; não existe protocolo específico para conduta quando há sofrimento do CAP; curativos podem ser removidos no primeiro dia de pós-operatório ou mantidos por mais tempo, e deve haver parcimônia no enxerto de gordura. Conclusão: O presente estudo concluiu que a mamoplastia é uma cirurgia segura, porém são necessários estudos continuados que possibilitem minimizar complicações.

ABSTRACT Introduction: Mammoplasty is one of the most performed surgeries by plastic surgeons. Like every procedure, it is not free of risks or complications. Objectives: Discuss controversial issues and complications in breast surgery and main treatments. Methods: Four full members of the SBCP with extensive experience in breast plastic surgery participated in the discussion, in addition to the regent of the mammoplasty chapter. Factors that presented the greatest controversy in mammoplasties were evaluated: use of antibiotics; preoperative infiltration; association of mammoplasty with breast implants; large mammary ptoses; masculinizing mammoplasty; flaps for the elevation of the nipple-areola complex (NAC); use of drains; dressings in mammoplasties and fat grafting. Results: The literature and discussion among specialists generated the observations: there is robust evidence of the effectiveness in the use of perioperative antibiotics of reducing mammoplasties, but there is no evidence of benefits in maintaining use for more than 24 hours; preoperative infiltration with vasoconstrictor solutions does not reduce the incidence of hematoma; in mammoplasty associated with implants there was no consensus on the best technique, plane or texture of the implant; there was no consensus on the best technique in the elevation of NAC in large ptoses, whether grafts or flaps; masculinizing mammoplasty does not present complications different from those found in the literature; there is no specific protocol for conduct when there is suffering from the NAC; dressings can be removed on the first postoperative day or kept longer, and there should be parsimony in the fat graft. Conclusion: The present study concluded that mammoplasty is safe surgery, but continued studies are needed to minimize complications.

Alcohol (70%) versus alcoholic chlorhexidine solution (0.5%) in skin antisepsis for neuraxial blocks: a randomized clinical trial.

OBJECTIVE: to compare the use of 0.5% alcoholic chlorhexidine and 70% alcohol in skin antisepsis for neuraxial blocks. METHOD: this is a non-inferiority randomized clinical trial, with two parallel arms. Seventy patients who were candidates for neuraxial block were randomly allocated to group A (n = 35), in whom antisepsis was performed with 0.5% alcoholic chlorhexidine, or to group B (n = 35), in whom we used 70% hydrated ethyl alcohol. Swabs were harvested for culture at three times: before antisepsis, two minutes after application of the antiseptic, and immediately after puncture. The samples were sown in three culture media and the number of colony forming units (CFU) per cm² was counted. RESULTS: there was no difference between the groups regarding age, sex, body mass index, time to perform the block or type of block. There were no differences between groups in the CFU/cm² counts before antisepsis. There was less bacterial growth in group B two minutes after application of the antiseptic (p = 0.048), but there was no difference between the groups regarding the number of CFU/cm² at the end of the puncture. CONCLUSION: 70% alcohol was more effective in reducing the number of CFU/cm² after two minutes, and there was no difference between the two groups regarding skin colonization at the end of the procedure. These results suggest that 70% alcohol may be an option for skin antisepsis before neuraxial blocks. Trial registration: ClinicalTrials.gov, NCT02833376.

RESUMO Objetivo: comparar o uso de solução alcoólica de clorexidina 0,5% e de álcool 70% na antissepsia da pele para bloqueios do neuroeixo. Método: ensaio clínico randomizado de não inferioridade, com dois braços paralelos. Foram selecionados 70 pacientes candidatos à bloqueio do neuroeixo, randomicamente alocados para o grupo A (n=35), em que a antissepsia foi realizada com clorexidina alcoólica 0,5%, ou para o grupo B (n=35), em que se utilizou álcool etílico hidratado 70%. Foram coletadas, com swab, amostras para cultura em três momentos: antes da antissepsia, dois minutos após aplicação do antisséptico, e imediatamente após a punção. As amostras foram semeadas em três meios de cultura e foi contabilizado o número de unidades formadoras de colônias (UFC) por cm². Resultados: não houve diferença entre os grupos quanto à idade, ao sexo, ao índice de massa corporal, ao tempo para realização do bloqueio ou tipo de bloqueio. Também não houve diferenças entre os grupos na contagem de UFC/cm² antes da antissepsia. Constatou-se menor crescimento bacteriano no grupo B dois minutos após aplicação do antisséptico (p=0,048), mas não houve diferença entre os grupos quanto ao número de UFC/cm² ao final da punção. Conclusão: o álcool 70% mostrou-se mais efetivo em reduzir o número de UFC/cm² após dois minutos, e não houve diferença entre os dois grupos quanto à colonização da pele ao final do procedimento. Esses resultados sugerem que o álcool 70% pode ser opção para antissepsia da pele antes de bloqueios do neuroeixo. Registro ensaio clínico: ClinicalTrials.gov, NCT02833376.

Antibiotic prophylaxis in breast cancer surgery. A randomized controlled trial.

PURPOSE: To assess the effect of antibiotic prophylaxis on surgical site infection (SSI) rates in women undergoing breast cancer surgery in two tertiary hospitals in Brazil. METHODS: This was a randomized, double-blind, placebo-controlled, parallel-group clinical trial. A total of 124 women without independent risk factors for SSI were randomly assigned to receive either cefazolin (antibiotic group, n = 62) or placebo (control group, n = 62) as preoperative prophylaxis. After surgery, all surgical wounds were examined once a week, for four weeks, according to the Centers for Disease Control and Prevention definitions and classifications for SSI. RESULTS: Baseline characteristics were homogeneous between the two groups. Only one patient in the antibiotic group developed SSI, which was classified as superficial incisional. The overall SSI rate was low, with no significant difference between groups. CONCLUSION: Antibiotic prophylaxis had no significant effect on reducing SSI rates in women without independent risk factors for SSI undergoing breast cancer surgery.

Cross-cultural validation of the FACE-Q Satisfaction with Facial Appearance Overall Scale (FACE-Q SFAOS) in Brazilian rhytidoplasty patients.

OBJECTIVES: This study aimed to culturally validate the FACE-Q - Satisfaction with Facial Appearance Overall Scale (Face-Q SFAOS) in a population of Brazilian rhytidoplasty patients. METHOD: Authorization for the translation and validation of the questionnaire was obtained from the FACE-Q SFAOS distribution rights holders. The FACE-Q SFAOS was translated and then back-translated. For cultural validation, a total of 57 women were selected 5 to 8 months after undergoing rhytidoplasty. Twenty of them participated in the cultural adaptation, 30 participated in the reproducibility analysis, and 57 participated in the construct validation. RESULTS: The analysis identified two factors (general appearance and face geometry) that exhibited excellent internal consistency. The total satisfaction score, which comprised nine items, also presented excellent internal consistency. Good reproducibility was found for Overall Appearance, Geometry and Total. There was a difference in the satisfaction means (total and factors) between procedure locations; patients undergoing frontal, upper eyelid and lower eyelid procedures were less satisfied than those who did not undergo such procedures. Satisfaction was higher with geometry than with overall face appearance. CONCLUSION: The FACE-Q SFAOS was adapted to the cultural context of Brazilian rhytidoplasty patients and was reproducible, and the scale exhibited face, content and construct validity.

Single dose versus 24 h antibiotic prophylaxis in reduction mammaplasty: study protocol for a randomized controlled trial.

BACKGROUND: Reduction mammaplasty is among the most commonly performed procedures in plastic surgery. Antibiotics are widely prescribed, on an empirical basis, to prevent surgical site infections. However, there is a lack of evidence to support its use. This trial aims to compare the influence of the use of prophylatic antibiotics as a single dose or for 24 h on surgical site infection rates following reduction mammaplasty. METHODS: Randomized trial of non-inferiority, with two parallel groups. A total of 146 breast hypertrophy patients, with reduction mammaplasty already scheduled, will be enrolled. Patients will be randomly allocated to the placebo group that will receive antibiotics only at the anesthesia induction (n = 73) or to the antibiotics group that will receive antibiotics at the anesthesia induction and for 24 h (n = 73). None of the patients will receive antibiotics after hospital discharge. Patients will be followed-up weekly, for 30 days, regarding surgical site infection. The Centers for Disease Control and Prevention criteria will be applied. A statistical analysis of the data will be performed. DISCUSSION: Previous studies have demonstrated a decrease in infection rates after reduction mammaplasty when antibiotic prophylaxis was used, compared to the use of no antibiotics. However, the duration of antibiotic prophylaxis remains a point to be clarified. This study will test the hypothesis that maintaining the use of antibiotics for 24 h does not reduce infection rates compared to the use of a single preoperative dose.
