Use of point-of-care ultrasound to assess the severity of scorpion stings in hospitalized patients.

INTRODUCTION: Scorpionism is a public health problem, especially in tropical regions. In Brazil, the prevalence of envenomation by scorpions is high, and the average national lethality is around 0.16 percent. The Tityus serrulatus scorpion is the primary species of medical importance. However, objective tools to predict and define the severity of these envenomations are lacking. MATERIALS AND METHODS: This was an observational study conducted among patients aged 0-19 years with scorpionism. Patients were admitted to a reference hospital between December 2020 and May 2022. Point-of-care ultrasound was performed within 24 hours of the scorpion sting. RESULTS: Forty-nine patients were included, with a median age of 3.6 (interquartile range 2.3-5.3) years and a predominance of females (51 percent). Fifteen patients (30.6 percent) presented major life-threatening signs, 32 (65.3 percent) minor systemic manifestations, and two (4.1 percent) only local manifestations. Left ventricular dysfunction was identified in 13 patients (26.5 percent). Ten patients (20.4 percent) presented pattern B (visualization of three or more B lines in the evaluated quadrant) in at least one lung window. The sensitivity and specificity of cardiac and pulmonary ultrasound to identify the most severely ill patients were 86 percent and 94 percent, respectively. DISCUSSION: The changes found on point-of-care ultrasound were associated with life-threatening signs. All patients with class III envenomation were referred to the intensive care unit, showing the importance of early identification of this subgroup. The main limitations were the small sample size and the fact that admission to intensive care was not based on systematic criteria. CONCLUSIONS: Point-of-care ultrasound is able to identify early signs of pulmonary congestion and heart failure in scorpionism. It can be useful for the objective selection of patients who are at a higher risk of complications and death and who require intensive support; it may also be valuable for periodic reassessments. Point-of-care ultrasound is a valuable tool for identifying and monitoring severe cases of scorpionism.

Compartmentalized Regulation of Pulmonary and Systemic Inflammation in Critical COVID-19 Patients.

Critical COVID-19 has been associated with altered patterns of cytokines. Distinct inflammatory processes in systemic and pulmonary sites have been reported, but studies comparing these two sites are still scarce. We aimed to evaluate the profile of pulmonary and systemic cytokines and chemokines in critically ill COVID-19 patients. Levels of cytokines and chemokines were measured in plasma samples and minibronchoalveolar lavage of critical COVID-19 patients within 48 h and 5-8 days after intubation. Distinct inflammatory processes were observed in the lungs and blood, which were regulated separately. Survivor patients showed higher lung cytokine levels including IFN-γ, IL-2, IL-4, G-CSF, and CCL4, while nonsurvivors displayed higher levels in the blood, which included IL-6, CXCL8, CXCL10, CCL2, and CCL4. Furthermore, our findings indicate that high TNF and CXCL8 levels in the mini-BAL were associated with better lung oxygen exchange capacity, whereas high levels of IFN-γ in plasma were associated with worse lung function, as measured using the PaO2/FiO2 ratio. These results suggest that a robust and localized inflammatory response in the lungs is protective and associated with survival, whereas a systemic inflammatory response is detrimental and associated with mortality in critical COVID-19.

Finite-Size Relaxational Dynamics of a Spike Random Matrix Spherical Model.

We present a thorough numerical analysis of the relaxational dynamics of the Sherrington-Kirkpatrick spherical model with an additive non-disordered perturbation for large but finite sizes N. In the thermodynamic limit and at low temperatures, the perturbation is responsible for a phase transition from a spin glass to a ferromagnetic phase. We show that finite-size effects induce the appearance of a distinctive slow regime in the relaxation dynamics, the extension of which depends on the size of the system and also on the strength of the non-disordered perturbation. The long time dynamics are characterized by the two largest eigenvalues of a spike random matrix which defines the model, and particularly by the statistics concerning the gap between them. We characterize the finite-size statistics of the two largest eigenvalues of the spike random matrices in the different regimes, sub-critical, critical, and super-critical, confirming some known results and anticipating others, even in the less studied critical regime. We also numerically characterize the finite-size statistics of the gap, which we hope may encourage analytical work which is lacking. Finally, we compute the finite-size scaling of the long time relaxation of the energy, showing the existence of power laws with exponents that depend on the strength of the non-disordered perturbation in a way that is governed by the finite-size statistics of the gap.

Pandemic's influence on parents' attitudes and behaviors toward meningococcal vaccination.

Invasive meningococcal disease is a life-threatening infection preventable through vaccination. Pediatric vaccination rates have declined during the coronavirus disease 2019 (COVID-19) pandemic. This survey aimed to understand how parents' attitudes and behaviors have changed during the pandemic with regard to immunization and, more specifically, meningococcal vaccination. An online survey was emailed to parents of eligible children 0-4 years, following the selection process from UK, France, Germany, Italy, Brazil, Argentina, and Australia; and of adolescents 11-18 years from US. Data collection took place 19 January-16 February 2021. Quotas were set to ensure a representative sample. Eleven questions relating to general perceptions around vaccination and attitudes and behaviors toward meningitis vaccination were displayed. On 4,962 parents (average 35 years) participating in the survey, most (83%) believed important for their child to continue receiving recommended vaccines during the COVID-19 pandemic. Nearly half of routine vaccine appointments were delayed or canceled due to the pandemic, and 61% of respondents were likely to have their children catch up once COVID-19 restrictions were lifted. 30% of meningitidis vaccination appointments were canceled or delayed during the pandemic, and 21% of parents did not intend to reschedule them because of lockdown/stay at home regulations, and fear of catching COVID-19 in public places. It is crucial to communicate clear instructions to health workers and the general population and to provide appropriate safety precautions in vaccination centers. This will help to maintain vaccination rates and limit infections to prevent future outbreaks.

What is the context? Invasive meningococcal disease (IMD) is an uncommon infection that can lead to permanent disabilities and even death.Meningitis vaccination can prevent IMDs caused by Neisseria meningitidis.Vaccination rates have declined during the coronavirus (COVID-19) pandemic.What is new? We collected opinion of parents from the UK, France, Germany, Italy, Brazil, Argentina, Australia, and the US, to understand their attitudes and behaviors toward meningitis vaccination during the COVID-19 pandemic.Results were reviewed by health care professional experts as well as by patient authors (IMD survivors).Most (83%) of the 4,962 parents believed that it is important for their child to continue receiving recommended vaccines during the COVID-19 pandemic.Half of the scheduled appointments for meningitis vaccination were canceled or delayed during the COVID-19 pandemic, mainly due to lockdown regulations and fear of catching COVID-19.Twenty-one percent of the parents who had their child's meningitis vaccination appointment canceled, did not intend to reschedule it.What is the impact? It is crucial that clear information is communicated by health care authorities and practitioners about the availability of vaccination during pandemic and the safety precautions that are taken.Collected opinions emphasize the importance of continuing vaccinations against infectious diseases during a pandemic.

First-line biologic therapy with tumor necrosis factor inhibitors for psoriatic arthritis: a prospective observational study

ABSTRACT BACKGROUND: Psoriatic arthritis (PsA) is a chronic inflammatory disease that affects multiple joints. It is associated with psoriasis and treated with synthetic and biologic drugs. OBJECTIVE: The objective of this study was to assess the outcomes of patients who received biologic therapy with tumor necrosis factor (TNF) inhibitors in terms of effectiveness, safety, functionality, and quality of life. DESIGN AND SETTING: A prospective observational study was performed at a single center in Belo Horizonte, Brazil. METHODS: Patients with PsA who received their first TNF inhibitor treatment were followed up for 12 months. Disease activity was measured using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Clinical Disease Activity Index (CDAI). Functionality was measured using the Health Questionnaire Assessment (HAQ), and quality of life was evaluated using the European Quality of Life Five Dimensions (EQ-5D). Multiple linear regression was used to identify predictors of the clinical response at 12 months. RESULTS: A total of 143 patients treated with adalimumab or etanercept were evaluated. Most of the clinical measures were significantly improved at 12 months. However, 31%-51% of the patients did not achieve good clinical control. No differences were observed between adalimumab and etanercept, except for poor functionality at 12 months among patients treated with etanercept. The main predictors of a worse clinical response were female sex, etanercept use, poor functionality, or lower quality of life at baseline. The main adverse reactions were alopecia, headache, injection site reaction, sinusitis, flu, dyslipidemia, and infections. CONCLUSION: TNF inhibitor therapy was effective and safe. However, despite improvements in clinical measures, most patients did not achieve satisfactory control of the disease.

Fast-track referral for health interventions during pregnancy: study protocol of a randomised pragmatic experimental study to reduce low birth weight in Portugal (STOP LBW).

INTRODUCTION: Low birth weight (LBW) is associated with a wide range of short-term and long-term consequences and is related to maternal psychosocial and behavioural determinants. The objective of this study is to estimate the effect of implementing fast-track referral for early intervention on psychosocial and behavioural risk factors-smoking, alcohol consumption, depression and physical violence-in reducing the incidence of LBW. METHODS AND ANALYSIS: Parallel superiority pragmatic clinical trial randomised by clusters. Primary healthcare units (PHCU) located in Portugal will be randomised (1:1) to intervention or control groups. Pregnant women over 18 years of age attending these PHCU will be eligible to the study. Risk factors will be assessed through face-to-face interviews. In the intervention group, women who report at least one risk factor will have immediate access to referral services. The comparison group will be the local standard of care for these risk factors. We will use intention-to-treat analyses to compare intervention and control groups. We estimated a sample size of 2832 pregnant women to detect a 30% reduction in the incidence rate of LBW between the control and intervention groups. Secondary outcomes are the reduction of preterm births, reduction of the four risk factors and acceptance of the intervention. ETHICS AND DISSEMINATION: The study was approved by the Ethics Committee of the Public Health Institute of the University of Porto (no CE20140). The findings will be disseminated to the public, the funders, health professionals, health managers and other researchers. TRIAL REGISTRATION NUMBER: NCT04866277.

Interaction effects of socio-economic position in the association between eating location and diet quality in Portuguese children and adolescents: results from the National Food, Nutrition and Physical Activity Survey 2015-2016.

This study aims to evaluate the interaction effect of socio-economic environment (SEE) in the relationship between the eating location (EL) and diet quality, in children and adolescents. Data included Portuguese children and adolescents (3-17 years) from a National Dietary Survey Sample (IAN-AF 2015/2016, n 987). Dietary intake was obtained by 2-d food diaries (children) or 2-24-h-recall (adolescents). Participants were classified into four groups of EL: 'Home', 'Other homes', 'School' and 'Restaurants'. Diet quality was measured as a higher adherence to a healthy eating pattern. A previous developed socio-economic classification was used, and participants were grouped as belonging to a low socio-economic environment (LSE) or middle-high socio-economic environment (MHSE). Linear regression models were used to evaluate the association between EL and diet quality, stratified by the SEE. A statistically significant interaction effect was found (P < 0·01) for the SEE in the association between EL and diet quality. After adjustment for potential confounders, in LSE, participants belonging to 'Other homes' (ß = -2·07; 95 % CI:-3·70, -0·44) and 'Restaurants' (ß = -3·31; 95 % CI: -5·08, -1·54) had lower scores in the diet quality score, comparing to 'Home'. In MHSE, comparing with 'Home', 'Restaurants' showed lower diet quality (ß = -1·56; 95 % CI:-2·65, -0·48), while the 'School' had better diet quality (ß = 0·90; 95 % CI: 0·16, 1·64). The SEE influences the association between EL and diet quality and, belonging to more disadvantaged SEE, might represent a higher risk of unhealthy eating habits when eating out-of-home.

Effectiveness and safety of anti-TNF therapy for ankylosing spondylitis: a real-world study.

Aim: To evaluate the effectiveness and safety of anti-TNF drugs for ankylosing spondylitis. Materials & methods: A prospective cohort study was performed at a pharmacy in the Brazilian Public Health System. Effectiveness by Bath Ankylosing Spondylitis Disease Activity Index, functionality by Health Assessment Questionnaire Disability Index, quality of life by European Quality of Life Five-Dimensions and safety was assessed at 6 and 12 months of follow-up. Results: About 160 patients started the treatment with adalimumab, etanercept or infliximab. There was a statistically significant improvement in disease activity, functionality and quality of life at 6 and 12 months (p < 0.05). Conclusion: This real-world study has shown that anti-TNF drugs are effective and well tolerated for ankylosing spondylitis patients.

FIRST LINE OF SUBCUTANEOUS ANTI-TNF THERAPY FOR RHEUMATOID ARTHRITIS: A PROSPECTIVE COHORT STUDY.

Objectives: This study aims to evaluate and compare the use of subcutaneous anti-TNF for RA in a Brazilian real-life setting. Methods: A prospective cohort of biological disease-modifying antirheumatic drug (bDMARD)-naïve patients treated with adalimumab, etanercept, golimumab, and certolizumab was developed. Medication persistence, disease activity by the Clinical Disease Activity Index (CDAI), functionality by the Health Assessment Questionnaire (HAQ), quality of life by the European Quality of Life 5 Dimensions (EQ-5D), and safety were evaluated at 6 and 12 months. Results: In a total of 327 individuals, 211 (64.5%) were persistent at 12 months. Patients improved after the use of anti-TNF, with a reduction in the mean of CDAI and HAQ, in addition to an increase in the mean of EQ-5D (p < 0.05). The number of patients who achieved the clinical response was 114 (34.86%) by CDAI, 212 (64.83%) by HAQ, and 215 (65.75%) by EQ-5D at 12 months. There were no statistically significant differences among the drugs (p > 0.05). The anti-TNF was well tolerated. Conclusion: Anti-TNF reduced disease activity, in addition to improving patients' functionality and quality of life. Additional pharmacotherapeutic monitoring can be essential to achieve better results.

Long distance training associated to HIIT protocol does not induce changes in blood biochemical markers in adult marathoners

ABSTRACT Objective: to verify blood markers during a 12-week training protocol and after Sao Paulo Marathon. Methods: Blood samples of 9 male marathoners were collected before (C1) and after (C2) 12-week training protocol, before (C3) and after (C4) marathon. Muscle and liver damage markers (creatine kinase [CK-MM], aspartate aminotransferase [AST], alanine aminotransferase [ALT]), oxidative stress levels (thiobarbituric acid reactive substances [TBARS]) and serum iron concentration were measured. Results: changes were identified comparing moment C4 to other moments for CK-MM and iron. For AST, ALT, and TBARS no differences were identified. Conclusion: strenuous exercises might elicit changes on blood markers, needing follow up strategies to avoid impairments to athletes' performance and health.

Effect of a school soccer competition with consecutive day games on the recovery status of U-19 players / Efeito de uma competição escolar de futebol com jogos em dias consecutivos no estado de recuperação de jogadores sub-19

Abstract The present study aimed to evaluate the effect of a school soccer competition with consecutive day games on the recovery status of U-19 players. Thirty-one school athletes (17.1±1.1 years) who played a U-19 school soccer competition (composed of two groups of four soccer teams each, followed by semifinals and final) were randomly evaluated. Games lasted 70 min (two periods of 35 min with 15 min rest interval), and they were played on consecutive days with 24 h between each game. Delayed onset muscle soreness (DOMS) and Total Quality Recovery (TQR) were measured before group phase games (n= 31) and semifinals games (n= 18). The internal game load was measured by the session rate of perceived exertion (session-RPE) method. TQR was higher before the first game when compared to the other games (p< 0.001). DOMS increased after the first game and did not return to baseline before the fourth game. Both session-RPE and internal load of the fourth game were higher than in the other games (p< 0.001). In addition, there was no correlation between internal game load and TQR (p> 0.05). The monotony observed during the evaluated period was 3.1±2.0 AU. The results indicate that the 24 h rest period seems to be insufficient for complete recovery of U-19 soccer school athletes, suggesting the organization of U-19 school soccer competitions with higher rest interval between games and search for methods to increase the recovery rate.

Resumo O presente estudo objetivou analisar o efeito de uma competição escolar de futebol com jogos em dias consecutivos no estado de recuperação física de jogadores sub-19. Foram avaliados, de forma aleatória, 31 atletas escolares (17,1±1,1 anos) participantes de uma competição escolar de futebol de campo sub-19, composta de duas chaves com quatro equipes cada, seguido de semifinais e final. Os jogos tiveram 70 min de duração (dois tempos de 35 min com 15 min de intervalo), e foram realizados em dias consecutivos com intervalo de 24h entre cada jogo. Foi medida a dor muscular de início tardio (DOMS) e Qualidade Total de Recuperação (QTR) antes de cada jogo da primeira fase (n= 31) e da semifinal (n=18). A carga interna dos jogos foi medida a pelo método da percepção subjetiva do esforço da sessão (PSE-sessão). A QTR foi maior antes do primeiro jogo em comparação com os demais jogos (p< 0.001). A DOMS aumentou após o primeiro jogo e não retornou aos valores basais antes do quarto jogo (p< 0.001). A PSE-sessão e a carga interna do quarto jogo foram maiores que as dos demais jogos (p< 0,001). Em adição, não houve correlação entre a carga interna do jogo e a QTR (p> 0,05). A monotonia encontrada no período avaliado foi de 3,1±2.0 UA. Os resultados indicam que o período de 24h parece ser insuficiente para a completa recuperação de atletas escolares de futebol sub-19, sugerindo a organização de competições escolares de futebol sub-19 com maior intervalo entre os jogos e busca por métodos que acelerem a recuperação.

Conventional and right-sided screening for subcutaneous ICD in a population with congenital heart disease at high risk of sudden cardiac death.

BACKGROUND: Information regarding suitability for subcutaneous defibrillator (sICD) implantation in tetralogy of Fallot (ToF) and systemic right ventricle is scarce and needs to be further explored. The main objective of our study was to determine the proportion of patients with ToF and systemic right ventricle eligible for sICD with both, standard and right-sided screening methods. Secondary objectives were: (i) to study sICD eligibility specifically in patients at high risk of sudden cardiac death, (ii) to identify independent predictors for sICD eligibility, and (iii) to compare the proportion of eligible patients in a nonselected ICD population. METHODS: We recruited 102 patients with ToF, 33 with systemic right ventricle, and 40 consecutive nonselected patients. Conventional electrocardiographic screening was performed as usual. Right-sided alternative screening was studied by positioning the left-arm and right-arm electrodes 1 cm right lateral of the xiphoid midline. The Boston Scientific ECG screening tool was utilized. RESULTS: In high-risk patients with ToF, eligibility was higher with right-sided screening in comparison with standard screening (61% vs. 44%; p = .018). Eligibility in high-risk right ventricle population was identical with both screening methods (77%, p = ns). The only independent predictor for sICD eligibility was QRS duration. CONCLUSION: In high-risk patients with ToF, right-sided implantation of the sICD could be an alternative to a conventional ICD. In patients with a systemic right ventricle, implantation of a sICD is an alternative to a conventional sICD.

The Role of Conventional and Right-Sided ECG Screening for Subcutaneous ICD in a Tetralogy of Fallot Population.

BACKGROUND: Information regarding suitability for subcutaneous implantable cardioverter-defibrillator (S-ICD) implant in tetralogy of Fallot (ToF) population is scarce and needs to be further explored. THE AIMS OF OUR STUDY WERE: (1) to determine the proportion of patients with ToF eligible for S-ICD, (2) to identify the optimal sensing vector in ToF patients, (3) to test specifically the eligibility for S-ICD with right-sided screening, and (4) to compare with the proportion of eligible patients in a nonselected ICD population. METHODS: We recruited 60 consecutive patients with ToF and 40 consecutive nonselected patients. Conventional electrocardiographic screening was performed as usual. Right-sided alternative screening was studied by positioning the left arm and right arm electrodes 1 cm right lateral to the xiphoid midline. The Boston Scientific electrocardiogram (ECG) screening tool was utilized. RESULTS: We found a higher proportion of patients with right-sided positive screening in comparison with standard screening (77 ± 0.4% vs. 67 ± 0.4%; P < 0.0001) and a trend to higher number of appropriate leads in right-sided screening (1.3 ± 1 vs. 1.1 ± 1 ms; P = 0.07). Patients who failed the screening had a longer QRS duration and longer QT interval. Standard and right-sided screening showed a higher percent of positive patients in the control group compared to ToF patients (P < 0.001). CONCLUSION: Right-sided screening was associated with a significant 10% increase in S-ICD eligibility in ToF patients. When comparing with an acquired cardiomyopathies group, ToF showed a lower eligibility for S-ICD. The most appropriate ECG vector was the alternate vector in contrast to what is observed in the general population.

Dismorfofobia: o olhar do outro / Dysmorphophobia: to be seen through someone else's eyes

O modus vivendi moderno tem produzido cada vez mais um crescente descontentamento em relação à anatomia corporal e a imaginação a respeito do corpo perfeito desperta um desejo no indivíduo nem sempre condizente com sua realidade. Sem limitação para as transfigurações, o corpo é modelado com base no sonho de uma estrutura corporal perfeita, na maioria das vezes, inalcançável, com os inúmeros procedimentos cirúrgicos propostos. Assim, é fundamental que os cirurgiões plásticos conheçam o Transtorno Dismórfico Corporal (TDC) ou dismorfofobia, desordem esta prevalente em ambos os sexos, em que a visão da aparência é deturpada, caracterizada pela inquietação excessiva de uma imperfeição física minúscula ou por imperfeições corporais ilusórias. O diagnóstico pode passar despercebido pelo não conhecimento, pelo subdiagnóstico ou pela preocupação apenas com a alteração corporal, o que pode trazer prejuízos pessoais, demandas jurídicas e até ajudar a manter o distúrbio.

The modern modus vivendi has promoted a growing discontentment in regard to self body image, and imagining a perfect body leads to a desire in an individual that is not always compatible with reality. With no limits in transfiguration, the body is modeled based on the dream of a perfect body structure, which is most times unattainable and requires numerous proposed surgical procedures. Therefore, it is of utmost importance for plastic surgeons to become aware of Body Dysmorphic Disorder (BDD), or dysmorphophobia. This is a disorder that is prevalent in both sexes, in which self visual appearance is distorted. It is also characterized by an excessive concern over a tiny physical imperfection or delusive physical imperfections. The diagnosis can remain unnoticed due to lack of knowledge, misdiagnosis, or concern only over body alterations, which may lead to personal damage, legal claims, and also risk of prolonging the disorder.

Mastoplastia de aumento com inclusão de implante de silicone associado a mastopexia com abordagem inicial periareolar (safety pocket) / Evaluation of the L shaped scar reducing mastoplasty technique for breast hypertrophies", "_e": "n

INTRODUÇÃO: A mastopexia com inclusão de implante mamário é uma cirurgia desafiadora e de alta complexidade. No Brasil, observa-se crescente interesse pelo volume mamário maior; entretanto, em certos casos, apenas a inclusão do implante de silicone não é suficiente para confecção de uma mama cônica e de polo superior cheio. Para obtenção desse resultado é necessária a correção da flacidez cutânea mamária, com retirada do excesso de pele. MÉTODO: A abordagem inicial foi realizada com incisão periareolar semicircular inferior, que serviu como acesso à loja mamária em plano subfascial para inclusão do implante. Após o posicionamento do implante, o excedente de pele foi analisado com pontos simples e marcação com azul de metileno previamente à secção cutânea. Sempre que possível, a marcação em fuso longitudinal foi preferida, mas também foi utilizada a marcação em "L" ou "T" invertido, quando o excesso de pele era maior. RESULTADOS: Foram analisadas 49 pacientes, com idades entre 20 anos e 68 anos, sendo 28 mamas primárias e 21 mamas secundárias. As cirurgias para pexia de mamas com cicatriz resultante em "L" foram realizadas em 23 pacientes, em "T", em 8 casos, e cicatriz vertical, em 18. Foram observadas 6 complicações nesse grupo de pacientes: hematomas (n = 2), retração cicatricial (n = 2), equimose intensa (n = 1) e esteatonecrose (n = 1). CONCLUSÕES: A conduta conservadora da retirada de pele após o implante das próteses, a via de acesso periareolar e a utilização do plano subfascial são pontos diferenciais e relevantes dessa técnica. Essa técnica é considerada também mais segura, pois a única perda da solução de continuidade do meio com os tecidos se dá pela incisão periareloar. Dessa forma, não há exposição da prótese ao ser confeccionada a mastopexia.

BACKGROUND: Mastopexy with breast implant surgery is a challenging and highly complex surgical procedure. In Brazil, there is growing interest in larger breast volumes, although in certain cases, the sole addition of silicone implants is not sufficient for constructing a conical breast with a full upper pole. To obtain this result, it is necessary to correct sagging breasts by removing excess skin. METHODS: The initial approach was made with an inferior semicircular periareolar incision, which provided subfascial access to the breast pocket for inclusion of the implant. After implant placement, the excess skin was marked using simple stitches and staining with methylene blue prior to resection. Longitudinal spindle marking was preferred whenever possible. However, "L" or inverted "T" markings were also used when excess skin amounts were greater. RESULTS: We analyzed 49 patients aged 20-68 years, of whom 28 were undergoing primary breast surgery and 21 were undergoing secondary breast surgery. The surgeries for breast pexia included L-shaped scars in 23 patients, T-shaped scars in 8 patients, and vertical scars in 18 patients. Six complications were observed in this group of patients: hematoma (n = 2), scar retraction (n = 2), severe ecchymosis (n = 1), and steatonecrosis (n = 1). CONCLUSIONS: The conservative skin removal approach after prosthesis implantation, periareolar access, and use of the subfascial plane are the differential and relevant points of this technique. This technique is also considered safer because the periareolar incision caused the only loss of continuity in the tissues. Therefore, the prosthesis was not exposed during mastopexy.
