RESUMO
BACKGROUND: With the recent association between breast implants and anaplastic large cell lymphoma, breast implants have become the focus of many warnings. Surgeons and health professionals are not involved in all the processes of the manufacturing and distribution of this product. Not all countries have breast implant factories that are easy for surgeons to visit and better understand the manufacturing process. METHODS: A questionnaire about breast implant manufacturing and distribution was validated in consensus and form. Two plastic surgeons visited eight factories and administered the questionnaire in the presence of a photographer, who documented that the questionnaire was answered in the same way for all visits. Once the visitors finished obtaining the information (questionnaire responses and video recording), this information was validated by a different member of a safety committee in Mexico. For the observations to be considered valid, the information from the questionnaire and the video must be presented. RESULTS: We visited eight factories: three in France (Sebbin, Arion and Eurosilicone), two in Costa Rica (Allergan and Motiva), one in Scotland (Nagor), one in Germany (Polytech) and one in Korea (Bellagel). In four factories (Eurosilicone, Motiva, Nagor and Sebbin), the information on the process for manufacturing an implant was observed and recorded (validated). The quality laboratory was visited, and video recording was performed in six factories (Bellagel, Eurosilicone, Motiva, Nagor, Polytech and Sebbin). CONCLUSION: It was possible to observe and verify that most of the companies that distribute breast implants in Mexico perform their manufacturing processes according to ISO standards. A breast implant registry can help people further understand how BIA-ALCL will behave in the future and allow more tests to better understand this pathology.

INTRODUCTION: Medical devices such as hip, knee, breast, vascular prostheses, among others, are very useful in different pathologies. We cannot doubt that their use is a great tool, besides being an advance in medicine; they provide a change in the quality of life of many patients; however, they are not exempt from adverse reactions and events. METHODS: We conduct a systematic review about lymphoma in the presences of prostheses other than breast implants. RESULTS: We selected 21 publications with a total of 24 patients. The largest number of prostheses was related to long bones in a total of 13 prostheses. The most frequent symptoms were: pain (52%), inflammation (24%), visible or palpable mass 20%. The most frequent type of lymphoma was non-Hodgkin B cell lymphoma in 14 cases. DISCUSSION: The presence of microparticles make biological degradation and wear of the implants, with macrophage and lymphocyte activation and the consequent production of proinflammatory cytokines such as tumor necrosis factor α, interleukin-1ß, interleukin-6, and prostaglandin 2 (PGE2). CONCLUSION: Lymphoma is not a common disease in patients with prostheses, and more data are needed to identify risk factors and make proper diagnoses.

INTRODUCTION: There is concern regarding the high incidence of thrombosis in plastic surgery patients. For this reason, we wanted to compare the results of the Caprini/Pannucci score in patients with and without a past history of thrombosis admitted for aesthetic plastic surgery. METHODS: This was a case-control study of 152 patients undergoing aesthetic plastic surgery procedures. We formed two groups: Group I had 70 patients who had thrombosis after aesthetic plastic surgery and group II had 82 patients without thrombosis. We studied the considered risk factors for thrombosis. We weighted the factors according to the OR and linear regressions. We then related them to the Caprini/Pannucci score. RESULTS: Patients in group I had a score of 5.68 versus 3.45 in group II (p < 0.001). There was a 9.86% increase in thrombosis for each increased point in the rating. A higher effectiveness of the Caprini score was found in the high-score group; the greatest flaw was in the low-scoring group. The sensitivity was 75.71%, and the specificity was 70.73%. The factors with the greatest impact were the infiltration of fat in the buttocks, degree of obesity and time of surgery. There was an increased risk of thrombosis in patients with gluteal fat injections, varicose veins, obesity and immune disorders as well as those who had previously given birth. CONCLUSION: To increase the effectiveness of the score and to use the score as a basis on which to decide upon prophylactic care, it is necessary to modify the score and add some factors.

INTRODUCTION: Anaplastic large cell lymphoma associated with breast implants is receiving increased attention. Most cases have been reported in Europe, North America (USA and Canada), Australia and New Zealand. Fewer cases have been reported in Latin America (including Mexico), Africa and Asia. METHODS: This report was delivered during our national plastic surgery meeting in Cancun in May 2017. Before the meeting, two participants reviewed the literature. The review was performed using the following information sources: PubMed, Embase, Cochrane, Fisterra, Google Scholar and LILACS, with entries from 1980 to August 2015 in several languages (English, Spanish, French and Portuguese). The results were revealed during the meeting to the other participants. The consensus was divided into two parts. The first part included an open-ended question regarding the incidence and prevalence of the problem. The second part included clinical scenarios with different items that were rated by the participants. After this activity, accordance among the responses was evaluated. RESULTS: Seven cases were reported during the meeting (3 from Mexico, 3 from Chile and 1 from Argentina). Fifty percent of the participants reported consulting with guidelines and clinical centers to help with potential cases. Most agreed that further studies must be done in cases of chronic seroma where the capsule plays an important role. DISCUSSION: A current debate exists about the incidence of this problem in Latin America because we did not report the same number of cases as Europe, Australia or North America. More studies are required to determine the differences among reports in Latin America. CONCLUSION: Most representatives agreed that further studies must be done. Concern is increasing, and the problem is known. Other factors involved may be considered, and the problem must not be ignored.

INTRODUCTION: Liposuction is a popular surgical procedure. As in any surgery, there are risks and complications, especially when combined with fat injection. Case reports of fat embolism have described a possible explanation as the puncture and tear of gluteal vessels during the procedure, especially when a deep injection is planned. METHODS: A total of 10 dissections were performed in five fresh cadavers. Each buttocks was divided into four quadrants. We focused on the location where the gluteal vessels enter the muscle and the diameter of the vessels. Colorant at two different angles was injected (30° and 45°). We evaluated the relation of the colorant with the main vessels. RESULTS: We found two perforators per quadrant. The thickness of the gluteal muscle was 2.84 ± 1.54 cm. The area under the muscle where the superior gluteal vessels traverse the muscle was located 6.4 ± 1.54 cm from the intergluteal crease and 5.8 ± 1.13 cm from the superior border of the muscle. The inferior gluteal vessels were located 8.3 ± 1.39 cm from the intergluteal crease and 10 ± 2.24 cm from the superior border of the muscle. When we compared the fat injected at a 30° angle, the colorant stayed in the muscle. Using a 45° angle, the colorant was in contact with the superior gluteal artery and the sciatic nerve. No puncture or tear was observed in the vessels or the nerve. CONCLUSIONS: The location where the vessels come in contact with the muscle, which can be considered for fat injection, were located in quadrants 1 and 3. A 30° angle allows for an injection into the muscle without passing into deeper structures, unlike a 45° injection angle.

Recent studies have shown a relationship between lymphoma and breast implants. We performed a meta-analysis about this problem. We found 80 cases, 50 of which were reported in the United States (62.5%). The average age was 52 years. The average time between breast implant surgery and lymphoma was 11 years. Forty-one percent of the breast implants were silicone, 42.19% were saline and 15.8% were unknown. The coverage of the breast implants was texturized in 21.3% and unknown in 78%. The most common brands were McGhan and Mentor. In 72.6% of the cases, the brand was unknown. The clinical findings were seroma (67.33%), nodes (13.8%), mass (22.1%), other (11.7%) and unknown (32%). The most common surgical treatment was capsulectomy and breast implant removal. In 97% of the cases, ALK was negative and 3% were positive. The most common marker was CD30. The most common chemotherapy regimen was CHOP. Three patients died. Two of the patients had extracapsular extension of the disease and breast cancer history. Lymphoma related with the breast implant was a different type of lymphoma, and in most cases, it was less aggressive. The disease was confined to the capsule. Few patients developed aggressive disease, were extracapsular and showed bad prognosis.
