RESUMEN
The infiltration of substances into the buttocks for esthetic purposes can cause local or systemic damage. These infiltrated substances, known as adjuvants, foreign substances, and polymers, often lack sufficient and frequently controversial evidence. To identify the systemic complications associated with substances locally infiltrated in the buttocks for treatment, we conducted a systematic review following the PRISMA criteria. Of 275 publications, 29 met the eligibility criteria: 3 systematic reviews, 6 case series, and 20 case reports. The study comprises 463 cases, mainly women (87%), with an average age of 39.94 years. The average time between infiltrations was 7.65 years. Infiltrated substances included silicone, oils, methyl methacrylate, guaiacol, sodium gadolinium, collagen, paraffin, and other unknown substances. The complications fell into three categories: local, systemic with inflammatory-immune response, and renal damage due to hypercalcemia induced by the granulomatosis caused by the substance. Treatment lacked uniformity, mainly focusing on the main effect. Surgical resection of affected tissue resulted in local and systemic improvement (renal, hypercalcemia, or inflammatory-immune) for most patients. Patients who received comprehensive treatment based on inflammatory-immune control, control of renal involvement, and resection of the tissue area that contained large amounts of the infiltrated substance had a better prognosis than those with diffuse infiltration and delayed treatment.

Postpartum haemorrhage (PPH) is a significant cause of maternal mortality globally, necessitating prompt and efficient management. This review provides a comprehensive exploration of endovascular treatment dimensions for both primary and secondary PPH, with a focus on uterine atony, trauma, placenta accreta spectrum (PAS), and retained products of conception (RPOC). Primary PPH, occurring within 24 h, often results from uterine atony in 70% of causes, but also from trauma, or PAS. Uterine atony involves inadequate myometrial contraction, addressed through uterine massage, oxytocin, and, if needed, mechanical modalities like balloon tamponade. Trauma-related PPH may stem from perineal injuries or pseudoaneurysm rupture, while PAS involves abnormal placental adherence. PAS demands early detection due to associated life-threatening bleeding during delivery. Secondary PPH, occurring within 24 h to 6 weeks postpartum, frequently arises from RPOC. Medical management may include uterine contraction drugs and hemostatic agents, but invasive procedures like dilation and curettage (D&C) or hysteroscopic resection may be required.Imaging assessments, particularly through ultrasound (US), play a crucial role in the diagnosis and treatment planning of postpartum haemorrhage (PPH), except for uterine atony, where imaging techniques prove to be of limited utility in its management. Computed tomography play an important role in evaluation of trauma related PPH cases and MRI is essential in diagnosing and treatment planning of PAS and RPOC.Uterine artery embolization (UAE) has become a standard intervention for refractory PPH, offering a rapid, effective, and safe alternative to surgery with a success rate exceeding 85% (Rand T. et al. CVIR Endovasc 3:1-12, 2020). The technical approach involves non-selective uterine artery embolization with resorbable gelatine sponge (GS) in semi-liquid or torpedo presentation as the most extended embolic or calibrated microspheres. Selective embolization is warranted in cases with identifiable bleeding points or RPOC with AVM-like angiographic patterns and liquid embolics could be a good option in this scenario. UAE in PAS requires a tailored approach, considering the degree of placental invasion. A thorough understanding of female pelvis vascular anatomy and collateral pathways is essential for accurate and safe UAE.In conclusion, integrating interventional radiology techniques into clinical guidelines for primary and secondary PPH management and co-working during labour is crucial.
RESUMEN
Human language is supported by a cortical network involving Broca's area, which comprises Brodmann Areas 44 and 45 (BA44 and BA45). While cytoarchitectonic homolog areas have been identified in nonhuman primates, it remains unknown how these regions evolved to support human language. Here, we use histological data and advanced cortical registration methods to precisely compare the morphology of BA44 and BA45 in humans and chimpanzees. We found a general expansion of Broca's areas in humans, with the left BA44 enlarging the most, growing anteriorly into a region known to process syntax. Together with recent functional and receptorarchitectural studies, our findings support the conclusion that BA44 evolved from an action-related region to a bipartite system, with a posterior portion supporting action and an anterior portion supporting syntactic processes. Our findings add novel insights to the longstanding debate on the relationship between language and action, and the evolution of Broca's area.

Scales to qualify the risk of thrombosis do not include all thrombogenic factors that are generated in esthetic plastic surgery. Methods: We performed a systematic review to assess the risk of thrombosis in plastic surgery. Thrombogenic factors in esthetic surgery were analyzed by a panel of experts. We proposed a scale with 2 versions. In the first version, factors were stratified according to their impact on the possible risk of thrombosis. The second version includes the same factors but in a simplified form. We evaluated the efficacy of the proposed scale by comparing it with the Caprini score; we scored the risk in 124 cases and controls. Results: Using the Caprini score, we found that 81.45% of the patients studied and 62.5% of the cases of thrombosis were observed in the low-risk group. Only 1 case of thrombosis was reported in the high-risk group. Using the stratified version of the scale, we found that the low-risk group comprised 25% of the patients, and there were no cases of thrombosis. The high-risk group included 14.51% of patients; 10 presented thrombosis (62.5%). The proposed scale was very effective in detecting both low-risk and high-risk patients undergoing esthetic surgery procedures.

INTRODUCTION: A rapid deploy of unexpected early impact of the COVID pandemic in Spain was described in 2020. Oncology practice was revised to facilitate decision-making regarding multimodal therapy for prevalent cancer types amenable to multidisciplinary treatment in which the radiotherapy component searched more efficient options in the setting of the COVID-19 pandemic, minimizing the risks to patients whilst aiming to guarantee cancer outcomes. METHODS: A novel Proton Beam Therapy (PBT), Unit activity was analyzed in the period of March 2020 to March 2021. Institutional urgent, strict and mandatory clinical care standards for early diagnosis and treatment of COVID-19 infection were stablished in the hospital following national health-authorities' recommendations. The temporary trends of patients care and research projects proposals were registered. RESULTS: 3 out of 14 members of the professional staff involved in the PBR intra-hospital process had a positive test for COVID infection. Also, 4 out of 100 patients had positive tests before initiating PBT, and 7 out of 100 developed positive tests along the weekly mandatory special checkup performed during PBT to all patients. An update of clinical performance at the PBT Unit at CUN Madrid in the initial 500 patients treated with PBT in the period from March 2020 to November 2022 registers a distribution of 131 (26%) pediatric patients, 63 (12%) head and neck cancer and central nervous system neoplasms and 123 (24%) re-irradiation indications. In November 2022, the activity reached a plateau in terms of patients under treatment and the impact of COVID pandemic became sporadic and controlled by minor medical actions. At present, the clinical data are consistent with an academic practice prospectively (NCT05151952). Research projects and scientific production was adapted to the pandemic evolution and its influence upon professional time availability. Seven research projects based in public funding were activated in this period and preliminary data on molecular imaging guided proton therapy in brain tumors and post-irradiation patterns of blood biomarkers are reported. CONCLUSIONS: Hospital-based PBT in European academic institutions was impacted by COVID-19 pandemic, although clinical and research activities were developed and sustained. In the post-pandemic era, the benefits of online learning will shape the future of proton therapy education.

Human language is supported by a cortical network involving Broca's area which comprises Brodmann Areas 44 and 45 (BA44, BA45). While cytoarchitectonic homolog areas have been identified in nonhuman primates, it remains unknown how these regions evolved to support human language.

We found a general expansion of Broca's areas in humans, with the left BA44 enlarging the most, growing anteriorly into a region known to process syntax. Together with recent functional studies, our findings show that BA44 evolved from a purely action-related region to a more expanded region in humans, with a posterior portion supporting action and an anterior portion supporting syntactic processes. Furthermore, our findings provide a solution for the longstanding debate concerning the structural and functional evolution of Broca's area and its role in action and language.
RESUMEN
Individual differences in the ability to process language have long been discussed. Much of the neural basis of these, however, is yet unknown. Here we investigated the relationship between long-range white matter connectivity of the brain, as revealed by diffusion tractography, and the ability to process syntactically complex sentences in the participants' native language as well as the improvement thereof by multiday training. We identified specific network motifs by singular value decomposition that indeed related white matter structural connectivity to individual language processing performance. First, for two such motifs, one in the left and one in the right hemisphere, their individual prevalence significantly predicted the individual language performance, suggesting an anatomical predisposition for the individual ability to process syntactically complex sentences. Both motifs comprise a number of cortical regions, but seem to be dominated by areas known for the involvement in working memory rather than the classical language network itself. Second, we identified another left hemispheric network motif, whose change of prevalence over the training period significantly correlated with the individual change in performance, thus reflecting training induced white matter plasticity. This motif comprises diverse cortical areas including regions known for their involvement in language processing, working memory and motor functions. The present findings suggest that individual differences in language processing and learning can be explained, in part, by individual differences in the brain's white matter structure. Brain structure may be a crucial factor to be considered when discussing variations in human cognitive performance, more generally.

BACKGROUND: Anemia is a frequent process of morbidity and mortality in body contouring procedures. In aesthetic surgery, there are no standardized processes to minimize bleeding during surgery. For this reason, a study was designed to implement patient blood management strategies to reduce bleeding and transfusions in patients undergoing body contouring operations. METHODS: From January of 2017 to May of 2018, a prospective cohort-type observational study was conducted, including two groups of patients undergoing single or combined body contouring procedures. The first group did not receive patient blood management strategies, whereas the second group did receive these strategies. These measures consisted of preoperative strategies to ensure the patient had optimal hemoglobin and hematocrit levels and supportive intraoperative measures to minimize blood loss. The results were validated with different statistical tests according to the variables studied. RESULTS: A total of 409 patients were included in the study and were divided into two groups. The anthropometric and hemoglobin variables were similar in both groups. The 207 patients for whom patient blood management strategies were implemented lost an average of 1.2 g/dl less hemoglobin at 72 hours than the 202 patients for whom patient blood management strategies were not implemented (p ≤ 0.0001). CONCLUSIONS: Patient blood management strategies, such as increasing hemoglobin before surgery, and strategies to minimize blood loss during surgery, proved to be effective at reducing bleeding in patients undergoing body contouring surgery, also decreasing the need to perform postoperative blood transfusions. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

BACKGROUND: Pulmonary artery enlargement (PAE) detected using chest computed tomography (CT) is associated with poor outcomes in chronic obstructive pulmonary disease (COPD). It is unknown whether nocturnal hypoxemia occurring in smokers, with or without COPD, obstructive sleep apnoea (OSA) or their overlap, may be associated with PAE assessed by chest CT. METHODS: We analysed data from two prospective cohort studies that enrolled 284 smokers in lung cancer screening programs and completing baseline home sleep studies and chest CT scans. Main pulmonary artery diameter (PAD) and the ratio of the PAD to that of the aorta (PA:Ao ratio) were measured. PAE was defined as a PAD ≥ 29 mm in men and ≥27 mm in women or as a PA:Ao ratio > 0.9. We evaluated the association of PAE with baseline characteristics using multivariate logistic models. RESULTS: PAE prevalence was 27% as defined by PAD measurements and 11.6% by the PA:Ao ratio. A body mass index ≥ 30 kg/m2 (OR 2.01; 95%CI 1.06-3.78), lower % predicted of forced expiratory volume in one second (FEV1) (OR 1.03; 95%CI 1.02-1.05) and higher % of sleep time with O2 saturation < 90% (T90) (OR 1.02; 95%CI 1.00-1.03), were associated with PAE as determined by PAD. However, only T90 remained significantly associated with PAE as defined by the PA:Ao ratio (OR 1.02; 95%CI 1.01-1.03). In the subset group without OSA, only T90 remains associated with PAE, whether defined by PAD measurement (OR 1.02; 95%CI 1.01-1.03) or PA:Ao ratio (OR 1.04; 95%CI 1.01-1.07). CONCLUSIONS: In smokers with or without COPD, nocturnal hypoxemia was associated with PAE independently of OSA coexistence.
RESUMEN
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.

The human insular cortex is a heterogeneous brain structure which plays an integrative role in guiding behavior. The cytoarchitectonic organization of the human insula has been investigated over the last century using postmortem brains but there has been little progress in noninvasive in vivo mapping of its microstructure and large-scale functional circuitry. Quantitative modeling of multi-shell diffusion MRI data from 413 participants revealed that human insula microstructure differs significantly across subdivisions that serve distinct cognitive and affective functions. Insular microstructural organization was mirrored in its functionally interconnected circuits with the anterior cingulate cortex that anchors the salience network, a system important for adaptive switching of cognitive control systems. Furthermore, insular microstructural features, confirmed in Macaca mulatta, were linked to behavior and predicted individual differences in cognitive control ability. Our findings open new possibilities for probing psychiatric and neurological disorders impacted by insular cortex dysfunction, including autism, schizophrenia, and fronto-temporal dementia.

The human arcuate fasciculus pathway is crucial for language, interconnecting posterior temporal and inferior frontal areas. Whether a monkey homolog exists is controversial and the nature of human-specific specialization unclear. Using monkey, ape and human auditory functional fields and diffusion-weighted MRI, we identified homologous pathways originating from the auditory cortex. This discovery establishes a primate auditory prototype for the arcuate fasciculus, reveals an earlier phylogenetic origin and illuminates its remarkable transformation.

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.

In the existing reports on combined procedures of abdominoplasty with Cesarean section or natural delivery, a high incidence of complications and poor aesthetic results are reported. We conducted a survey with the participation of 61 plastic surgeons who performed this procedure in 808 patients, with an average of 13.24 procedures per surgeon. In 783 procedures (96.9% of the cases), the combination was with Cesarean section and 25 procedures (3.13% of cases) were combined with vaginal delivery. The plastic surgery procedures were as follows: 242 abdominoplasty procedures (29.95%), 210 abdominoplasty plus liposuction procedures (25.99%), 18 mini abdominoplasty procedures (2.22%), 121 mini abdominoplasty and liposuction procedures (14.97%), and 217 liposuction procedures (26.85%). The following complications were reported: seroma in 255 cases (31.57%), thrombosis in 212 (26.23%), infection in 170 (21.03%), skin necrosis in 127 (15.71%), and hematoma in 42 (5.19%). There were three deaths due to thrombosis (0.4%). There were redundancy skin abdominal wall defects in 336 (41.66%) cases, unaesthetic scars in 291 (36.11%), abdominal wall defects in 134 (16.58%), unpleasant contours in 22 (2.72%), and rotational folds in 22 (2.72%). Fifty-five (90.16%) surgeons decided to stop delivering babies with these practices. The combination of abdominoplasty with Cesarean section or natural delivery has a high incidence of complications and poor aesthetic results; therefore, we make a strong recommendation to avoid this practice before the patient reaches sixth month postpartum.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

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.

Gluteal augmentation with fat has become one of the most common cosmetic procedures worldwide. Gluteal augmentation is designed to increase the volume and contour of the gluteal region. Intramuscular lipoinjection has been linked to multiple reports of severe complications, including death due to macro fat embolism (MAFE). The authors present the first reported case of survival and successful recovery after MAFE secondary to gluteal augmentation with fat. A 41-year-old woman, ASA II, was scheduled for augmentation mammaplasty, liposuction, and gluteal augmentation with fat. The patient was operated under general anesthesia with a total intravenous anesthesia technique. A total of 3.5 liters of fat was liposuctioned with no complications. The patient was then positioned in a lateral decubitus position for gluteal augmentation with fat. Right after the last injection, the anesthesiologist noticed a sudden change in capnography followed by hypotension, bradycardia, and hypoxemia. The first reaction in the operating room was to consider that the patient was experiencing a severe episode of fat embolism. She was then resuscitated and transferred to a tertiary facility for intensive care management. To our knowledge, this is the first case report of successful resuscitation in a patient experiencing severe MAFE after gluteal augmentation with fat. We believe that this patient survived the event due to early detection, aggressive management, and proper transfer to an intensive care unit. Level of Evidence: 5.

INTRODUCTION: Liposuction is one of the most popular plastic surgery procedures. As in any surgery, there are risks and complications, especially when combined with fat injection. Case reports of fat embolism have been reported. A possible explanation is the puncture and tearing of gluteal vessels during the procedure, especially when a deep injection is planned. OBJECTIVE: To identify the places where fat can be located after injection during a fat graft in the gluteus. METHODS: An experimental study was done in which colorant was injected in four directions using four different quadrants of the gluteus. We Injected 10 cc six times following clock hands until 60 cc were injected, and the cutaneous flap and the muscles were then elevated. Our main purpose was to describe where the colorant went and if it was in contact with the vessels (superior and inferior gluteal vessels). In total, four gluteus muscles were injected and dissected. RESULTS: Injection in the lower lateral quadrant was mainly into the muscle, and colorant was observed in the hypogastric vessels. The injection in the upper quadrants stayed mainly in the subcutaneous tissue. CONCLUSIONS: During surgery, it is important to identify the location of the perforators and to avoid a deep injection, especially from the lower lateral quadrant to the superior medial quadrant (Q4 to Q1), as the probability of puncturing and injecting fat into the main vessels from this direction is higher.

BACKGROUND: Deaths secondary to gluteal lipoinjection are relatively recent events of major importance. However, little is known in relation to their behavior and clinical evolution. Therefore, an analysis was performed of case records from clinical cases that encountered this problem, correlating the results with the findings during autopsies. METHODS: An analysis was performed of records from patients who died secondary to gluteal lipoinjection. Patient-specific data, surgical procedure, clinical picture, evolution, and outcome were analyzed. The findings of the autopsies and the involvement of other organs were also analyzed and correlated. RESULTS: From 2000 to 2009, 16 files were obtained that fulfilled the indicated requirements. There were no statistically significant differences in the general characteristics of the patients, such as age, body mass index, or volume lipoinjected or liposuctioned. The clinical pictures were similar in all cases, and the autopsy findings showed the presence of microembolism in all cases and macroembolism in the most severe cases. CONCLUSIONS: The most significant parameter of severity in patients who undergo gluteal lipoinjection is the presence of fat in macroscopic form in the circulation. The volumes of liposuctioned or lipoinjected fat have little influence. Hypoxemia, hypotension, and bradycardia are the characteristic clinical features. Although there is no specific treatment, immediate aggressive vital support to attempt to stabilize the patient is crucial. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

BACKGROUND: Little is known about educational games in Plastic Surgery training. Pecha kucha game has proved to be helpful tool to improve communicative skills. This study survey in resident participants in Pecha Kucha contest assessed how to improve speaking skills in plastic surgery training. METHODS: In the second edition of Pecha Kucha contest of the Mexican Society of Plastic Surgery, a survey was conducted with the residents to know the utility of this educational game. RESULTS: Twenty-six residents participated in the survey. Most of them from the Universidad Nacional Autonoma de México. Most of the residents considered it to be a good tool in order to improve communication skills and helpful for their future practice. The amount of time to present an idea was considered enough to express an idea. The most common proportion between words and images was 20-80% in the presentation. CONCLUSION: Pecha Kucha helped to improve communication skills during residents' training. We encourage other plastic surgery societies to incorporate educational games in their national and international meetings.
