Interventions to de-implement unnecessary antibiotic prescribing for ear infections (DISAPEAR Trial): protocol for a cluster-randomized trial.

BACKGROUND: Watchful waiting management for acute otitis media (AOM), where an antibiotic is used only if the child's symptoms worsen or do not improve over the subsequent 2-3 days, is an effective approach to reduce antibiotic exposure for children with AOM. However, studies to compare the effectiveness of interventions to promote watchful waiting are lacking. The objective of this study is to compare the effectiveness and implementation outcomes of two pragmatic, patient-centered interventions designed to facilitate use of watchful waiting in clinical practice. METHODS: This will be a cluster-randomized trial utilizing a hybrid implementation-effectiveness design. Thirty-three primary care or urgent care clinics will be randomized to one of two interventions: a health systems-level intervention alone or a health systems-level intervention combined with use of a shared decision-making aid. The health systems-level intervention will include engagement of a clinician champion at each clinic, changes to electronic health record antibiotic orders to facilitate delayed antibiotic prescriptions as part of a watchful waiting strategy, quarterly feedback reports detailing clinicians' use of watchful waiting individually and compared with peers, and virtual learning sessions for clinicians. The hybrid intervention will include the health systems-level intervention plus a shared decision-making aid designed to inform decision-making between parents and clinicians with best available evidence. The primary outcomes will be whether an antibiotic was ultimately taken by the child and parent satisfaction with their child's care. We will explore the differences in implementation effectiveness by patient population served, clinic type, clinical setting, and organization. The fidelity, acceptability, and perceived appropriateness of the interventions among different clinician types, patient populations, and clinical settings will be compared. We will also conduct formative qualitative interviews and surveys with clinicians and administrators, focus groups and surveys of parents of patients with AOM, and engagement of two stakeholder advisory councils to further inform the interventions. DISCUSSION: This study will compare the effectiveness of two pragmatic interventions to promote use of watchful waiting for children with AOM to reduce antibiotic exposure and increase parent satisfaction, thus informing national antibiotic stewardship policy development. CLINICAL TRIAL REGISTRATION: NCT06034080.

Comparative analysis of upfront stereotactic radiosurgery and watchful waiting in the management of newly diagnosed vestibular schwannomas: a systematic review and meta-analysis.

Vestibular schwannomas (VS) are benign intracranial tumors posing significant management challenges. This study aims to compare the outcomes of stereotactic radiosurgery (SRS) and watchful waiting (WW) in the management of newly diagnosed VS, integrating findings from both retrospective and the pioneering V-REX prospective trial. Adhering to PRISMA guidelines, a systematic review was conducted using MEDLINE, Embase, and Cochrane databases. Studies directly comparing SRS with WW for newly diagnosed VS were included. Primary outcomes focused on hearing preservation assessed through the AAO-HNS or Gardner-Robertson hearing classification scales and tumor progression, with secondary outcomes focusing on neurological symptoms, and the need for further treatment. Thirteen studies encompassing 1,635 patients (WW: 891; SRS: 744) were included.While no significant difference was found in serviceable hearing loss at last follow-up (RR = 1.51, [95%CI: 0.98, 2.32], p = 0.06), significant differences favoring WW were observed in pure tone audiometry (PTA) (MD = -13.51 [95%CI: -22.66, -4.37], p = 0.004) and word recognition score (WRS) (MD = 20.48 [95%CI: 9.72, 31.25], p = 0.0002). Analysis of tumor progression indicated no overall significant difference in risk between SRS and WW (RR = 0.40, [95%CI 0.07, 2.40], p = 0.32), but subgroup analysis suggested a lower risk with SRS in certain contexts. The need for further treatments favored SRS (RR = 0.24, [95%CI: 0.07, 0.74], p = 0.007). No significant differences were found in tinnitus and imbalance between the two groups. This comprehensive analysis suggests no marked difference in functional hearing preservation between SRS and WW in managing VS. However, untreated tumors commonly necessitate additional interventions. These findings highlight the need for individualized treatment decisions and underscore the importance of continued monitoring. The study advocates for further prospective trials to refine management strategies for VS.

Conservative or surgical management of orbital schwannomas: a population-based case series.

INTRODUCTION: Orbital schwannomas (OS) are rare occurrences with no more than 500 cases reported in the literature. The tumor's potential to compromise the delicate neuro-ophthalmic structures within the orbit prompts surgical removal. Tumor removal is performed by ophthalmologists, often requiring a multidisciplinary surgical approach. The literature contains a very limited number of cases managed non-surgically. However, the inherent risks of orbital surgery warrant a comparison of the outcomes of conservative and surgical management strategies. AIMS: To review the national Swedish experience with the management of orbital schwannomas. METHODS: The study center is the primary Swedish referral center for the multidisciplinary management of orbital tumors, including schwannomas. During the period of 2005 to 2021, 16 patients with an OS diagnosis were managed at the center. RESULTS: Four patients initially underwent surgery where gross total resection (GTR) was achieved in three (75%) and subtotal resection (STR) in one (25%) case. The remaining 12 patients, who had a low risk of neuro-ophthalmic impairment, were managed conservatively with radiological and clinical examinations at regular intervals. After an average follow-up of 17 months, surgery was performed in three of these cases (25%). No recurrences or tumor growths were detected on radiological follow-ups (mean 50 months), and all patients experienced postoperative improvement at clinical follow-up (mean 65 months). The remainder of the conservatively treated patients (n=9) experienced no clinical progression (mean 30 months). A slight radiological tumor progression was detected in one patient after 17 months. CONCLUSION: There were no differences in long-term outcome between patients who had been managed with early surgery and those operated later after an initially conservative management. Conservatively treated patients had minimal to no symptoms and remained clinically stable throughout the follow-up period. Based on these findings, conservative management may successfully be adopted in cases with mild symptoms, no signs of compressive optic neuropathy and low risk of neuro-ophthalmic impairment. Conversion to surgical management is indicated upon clinical deterioration or tumor growth. Based on the findings of this study a decision tree for the management of orbital schwannomas is suggested.

Personalized Treatment Strategy in "Low-Risk Prostate Cancer Active Surveillance Candidates" Using Irreversible Electroporation: Prospective Evaluation of Feasibility, Morbidity, Functional and Oncological Outcomes.

PURPOSE: To evaluate the morbidity, functional and oncological outcome of irreversible electroporation (IRE) as a focal therapy for prostate cancer (PCa) when used in "active surveillance (AS)" candidates refusing standard treatment options. MATERIALS AND METHODS: IRE was performed under general anaesthesia, and the transurethral catheter was removed one day after intervention in all patients. Pre- and post-interventional voiding parameters (measured by International Prostate Symptom Score Questionnaire [IPSS], uroflowmetry and post-void residue) were compared. Follow-up (FU) was observed over a minimum of six months, including oncological outcome (controlled by multiparametric magnetic resonance imaging, rebiopsy, prostate-specific antigen dynamic as well as the need and type of secondary treatment) and general functional outcome (International Index of Erectile Function Questionnaire, satisfaction of the procedure). RESULTS: Twenty-four patients refusing AS or standard treatment with a median FU of 18.7 months were included. IPSS showed nine patients with mild, 12 with moderate and two with severe obstructive voiding symptoms pre-intervention (focal IRE). Median IPSS pre-IRE was 9 points, 8.5 (p=0.341) at six months and 10 (p=0.392) after 12 months, respectively. Pre-IRE maximum urinary flow (Qmax) (median: 16.1±8.0 mL/sec) and Qmax after catheter removal (16.2±7.6 mL/sec) did not differ significantly (p=0.904). Thirteen PCa recurrences occurred (54.2%). Out-of-lesion-PCa was found in 12/13 patients (92.3%), while 4/13 patients showed in-lesion-PCa recurrence simultaneously (30.8%). In one patient, there was an in-lesion-PCa recurrence only (7.7%). Six out of 24 patients (25.0%) received a secondary treatment. All patients were satisfied with the IRE procedure. CONCLUSIONS: Focal IRE underperforms regarding the overall oncological outcome and should not be offered as an equivalent therapy to established curative treatment strategies. Nevertheless, under a strict FU regimen, its lack of significant additional morbidity compared to an active surveillance strategy makes IRE a feasible alternative for low-risk PCa in highly selected patients as a personalised approach.

MRI-Targeted Prostate Biopsy Introduces Grade Inflation and Overtreatment.

Purpose: The use of MRI-targeted biopsies has led to lower detection of Gleason Grade Group 1 (GG1) prostate cancer and increased detection of GG2 disease. Although this finding is generally attributed to improved sensitivity and specificity of MRI for aggressive cancers, it might also be explained by grade inflation. Our objective was to determine the likelihood of definitive treatment and risk of post-treatment recurrence for patients with GG2 cancer diagnosed using targeted biopsies relative to men with GG1 cancer diagnosed using systematic biopsies. Methods: We performed a retrospective study on a large tertiary centre registry (HUS Acamedic Datalake) to retrieve data on prostate cancer diagnosis, treatment, and cancer recurrence. We included patients with either GG1 with systematic biopsies (3317 men) or GG2 with targeted biopsies (554 men) from 1993 to 2019. We assessed the risk of curative treatment and recurrence after treatment. Kaplan-Meier survival curves were computed to assess treatment- and recurrence-free survival. Cox proportional hazards regression analysis was performed to assess the risk of posttreatment recurrence. Results: Patients with systematic biopsy detected GG1 cancer had a significantly longer median time-to-treatment (31 months) than those with targeted biopsy detected GG2 cancer (4 months, p<0.0001). The risk of recurrence after curative treatment was similar between groups with the upper bound of 95% CI, excluding an important difference (HR: 0.94, 95% CI [0.71-1.25], p=0.7). Conclusion: GG2 cancers detected by MRI-targeted biopsy are treated more aggressively than GG1 cancers detected by systematic biopsy, despite having similar oncologic risk. To prevent further overtreatment related to the MRI pathway, treatment guidelines from the pre-MRI era need to be updated to consider changes in the diagnostic pathway.

Watchful waiting to surgery in men with mildly symptomatic or asymptomatic inguinal hernia: an individual participant data meta-analysis of long-term follow-up of randomized controlled trials.

BACKGROUND: Individual studies on men with mildly symptomatic or asymptomatic inguinal hernia who have opted for watchful waiting (WW) vary considerably. Furthermore, long-term data on such patients who cross over to herniorrhaphy is scarce. METHODS: PubMed, EMBASE, and Cochrane databases were searched systematically from inception to 3rd April 2024 for long-term follow-up of randomized controlled trials (RCTs) on men with mildly symptomatic or asymptomatic inguinal hernia. Individual participant survival data of cross over rates from WW to herniorrhaphy were extracted, reconstructed and combined. Secondary outcome was reason for cross over to herniorrhaphy. RESULTS: Long-term follow-up of three RCTs with 592 participants was included. A total of 344/592 participants crossed over to herniorrhaphy during a median follow up period that ranged from 3.2 to 12.0 years. The median cumulative cross over rate was 54.2% (95% CI 45.5% - 66.3%). The cumulative 1-year, 5-year, and 10- year cross over rates were 28.7% (95% CI 25.2% - 32.5%), 51.5% (95% CI 47.4% - 55.6%), and 70.6% (95% CI 66.2% - 74.9%) respectively. During follow-up, the most frequent reasons for cross over to herniorrhaphy were increased pain 198/344 (57.6%) and incarceration 15/344 (4.4%). CONCLUSION: This study provides valuable long-term data for patient counselling, indicating that while WW is a safe strategy for men with mildly symptomatic or asymptomatic inguinal hernia, symptoms would likely progress eventually, necessitating operative repair.

Active Surveillance for Low-Risk Thyroid Cancers: A Review of Current Practice Guidelines.

The indolent nature and favorable outcomes associated with papillary thyroid microcarcinoma have prompted numerous prospective studies on active surveillance (AS) and its adoption as an alternative to immediate surgery in managing low-risk thyroid cancer. This article reviews the current status of AS, as outlined in various international practice guidelines. AS is typically recommended for tumors that measure 1 cm or less in diameter and do not exhibit aggressive subtypes on cytology, extrathyroidal extension, lymph node metastasis, or distant metastasis. To determine the most appropriate candidates for AS, factors such as tumor size, location, multiplicity, and ultrasound findings are considered, along with patient characteristics like medical condition, age, and family history. Moreover, shared decision-making, which includes patient-reported outcomes such as quality of life and cost-effectiveness, is essential. During AS, patients undergo regular ultrasound examinations to monitor for signs of disease progression, including tumor growth, extrathyroidal extension, or lymph node metastasis. In conclusion, while AS is a feasible and reliable approach for managing lowrisk thyroid cancer, it requires careful patient selection, effective communication for shared decision-making, standardized follow-up protocols, and a clear definition of disease progression.

Complex Management of Basal Cell Carcinoma in a Frail Patient.

Basal cell carcinoma (BCC) is one of the most common cancers diagnosed in older patients and has low mortality. Surgical versus medical management is considered in patients with multiple comorbidities and limited life expectancy (LLE), where the risk-to-benefit ratio must be carefully assessed. Watchful waiting (WW) is a viable option for some patients with severe LLE when follow-up care can be provided vigilantly and frequently. Special consideration should be given to morbidity factors such as tumor growth, bleeding, pain, and social withdrawal that negatively affect the quality of life. We present the case of a 75-year-old male with a past medical history of multiple system atrophy, who presented with a BCC on the ear and face. We discuss the management of this patient and factors that may have led to the inappropriate use of WW.

The effectiveness of glucocorticoid treatment in post-COVID-19 pulmonary involvement.

RATIONALE: Persistent respiratory symptoms following Coronavirus Disease 2019 (COVID-19) are associated with residual radiological changes in lung parenchyma, with a risk of development into lung fibrosis, and with impaired pulmonary function. Previous studies hinted at the possible efficacy of corticosteroids (CS) in facilitating the resolution of post-COVID residual changes in the lungs, but the available data is limited. AIM: To evaluate the effects of CS treatment in post-COVID respiratory syndrome patients. PATIENTS AND METHODS: Post-COVID patients were recruited into a prospective single-center observational study and scheduled for an initial (V1) and follow-up visit (V2) at the Department of Respiratory Medicine and Tuberculosis, University Hospital Olomouc, comprising of pulmonary function testing, chest x-ray, and complex clinical examination. The decision to administer CS or maintain watchful waiting (WW) was in line with Czech national guidelines. RESULTS: The study involved 2729 COVID-19 survivors (45.7% male; mean age: 54.6). From 2026 patients with complete V1 data, 131 patients were indicated for CS therapy. These patients showed significantly worse radiological and functional impairment at V1. Mean initial dose was 27.6 mg (SD ± 10,64), and the mean duration of CS therapy was 13.3 weeks (SD ± 10,06). Following therapy, significantly better improvement of static lung volumes and transfer factor for carbon monoxide (DLCO), and significantly better rates of good or complete radiological and subjective improvement were observed in the CS group compared to controls with available follow-up data (n = 894). CONCLUSION: Better improvement of pulmonary function, radiological findings and subjective symptoms were observed in patients CS compared to watchful waiting. Our findings suggest that glucocorticoid therapy could benefit selected patients with persistent dyspnea, significant radiological changes, and decreased DLCO.

The Norwegian Watch and Wait study: Norwait for rectal cancer. A report from a failed study-a word of caution.

The paucity of prospective data on the subject of Watch and Wait for rectal cancer prompted the implementation of Norwait, a population-based study including rectal cancer patients after neoadjuvant therapy. The aim of the study was to assess the accuracy of clinical complete response (cCR) and quantify the regrowth rates. Norwait was a prospective population-based observational study with ethical approval (2017/935) registered at clinicaltrials.com (NTC03402477). Residents of Norway with histologically proven rectal cancer located within 15 cm from anal verge were eligible following completion of radiotherapy or chemoradiation at seven hospitals. cCR was the disappearance of tumour and of any ulcer with/without the appearance of whitening of prior tumour site and telangiectasia evaluated at 12 weeks by digital rectal exam, and endoscopic imaging. The study aimed to include 100 cCR patients with regrowth rates as primary endpoint. The data are presented in crude form. Eighty-two patients were included in seven hospitals from 2018 to 2020 when the study was terminated. Fifty-one patients were included in six hospitals, whereas protocol violations were identified in one hospital, where thirty-one (rather than protocol-estimated 12) patients were enrolled. Amongst the 31 patients, there were only 2 with documented cCR. Of the latter 29, there were 16 with ulcer or persistent tumour, and 13 without any documentation of cCR. Of these, 23 underwent surgery with a delay up to 50 weeks. At median 54-month follow-up of 31 patients, there were 77% local regrowths (n = 23), 40% metachronous metastases (n = 12) and 23% deaths (n = 7). At median 54-month follow-up of 51 cCR patients, there were 53% local regrowths (n = 27), 14% metachronous metastases (n = 7) and 4% deaths (n = 2). Norwait admonishes a word of caution reaching beyond the inconclusive results of a population-based study jeopardised by serious violation to protocol and legislation for conducting safe research.

Cost-Utility Analysis of Early Detection with Ultrasonography of Differentiated Thyroid Cancer: A Retrospective Study on a Korean Population.

BACKGRUOUND: There is debate about ultrasonography screening for thyroid cancer and its cost-effectiveness. This study aimed to evaluate the cost-effectiveness of early screening (ES) versus symptomatic detection (SD) for differentiated thyroid cancer (DTC) in Korea. METHODS: A Markov decision analysis model was constructed to compare the cost-effectiveness of ES and SD. The model considered direct medical costs, health outcomes, and different diagnostic and treatment pathways. Input data were derived from literature and Korean population studies. Incremental cost-effectiveness ratio (ICER) was calculated. Willingness-to-pay (WTP) threshold was set at USD 100,000 or 20,000 per quality-adjusted life year (QALY) gained. Sensitivity analyses were conducted to address uncertainties of the model's variables. RESULTS: In a base case scenario with 50 years of follow-up, ES was found to be cost-effective compared to SD, with an ICER of $2,852 per QALY. With WTP set at $100,000, in the case with follow-up less than 10 years, the SD was cost-effective. Sensitivity analysis showed that variables such as lobectomy probability, age, mortality, and utility scores significantly influenced the ICER. Despite variations in costs and other factors, all ICER values remained below the WTP threshold. CONCLUSION: Findings of this study indicate that ES is a cost-effective strategy for DTC screening in the Korean medical system. Early detection and subsequent lobectomy contribute to the cost-effectiveness of ES, while SD at an advanced stage makes ES more cost-effective. Expected follow-up duration should be considered to determine an optimal strategy for DTC screening.

International Variations in Adherence to Quality Metrics for Locoregional Prostate Cancer.

BACKGROUND AND OBJECTIVE: Adherence to guideline recommendations can improve the quality of care for patients with prostate cancer (PCa). Our aim was to assess adherence to guidelines for locoregional PCa by international region. METHODS: The study cohort comprised patients diagnosed with locoregional PCa in the 10-country Movember TrueNTH Global Registry (n = 62 688; 2013-2022). We assessed adherence to four quality metrics: (1) active surveillance for low-risk PCa; (2) definitive treatment within 12 mo of diagnosis for unfavorable-risk PCa; (3) no staging imaging for favorable-risk PCa; and (4) staging imaging for unfavorable-risk PCa. For χ2 analyses, we combined the three most recent years of data entered by region for each outcome, with adjustment for multiple tests (p = 0.05 ÷ 4 = 0.0125). We also conducted multivariable logistic regression and temporal analyses. KEY FINDINGS AND LIMITATIONS: Active surveillance rates for low-risk PCa ranged from 85% in Australia/New Zealand (vs USA: adjusted odds ratio [aOR] 1.042, 95% confidence interval [CI] 0.740-1.520) to 14% in Central Europe (aOR 0.028, 95% CI 0.022-0.036). For patients with unfavorable-risk disease, the highest uptake rate for treatment within 12 mo of diagnosis was in Central Europe (98%; aOR 2.885, 95% CI 1.260-6.603), compared to 70% in Italy (aOR 0.031, 95%CI 0.014-0.072). The proportion of patients with favorable-risk disease who did not undergo imaging ranged from 94% in the USA to 30% in Italy (aOR 0.004, 95% CI 0.002-0.008), while the rate of imaging for unfavorable-risk PCa ranged from 8% in Hong Kong (aOR 65.222, 95% CI 43.676-97.398) to 39% in the USA (all χ2p < 0.0125). Regional temporal trends also varied. CONCLUSIONS AND CLINICAL IMPLICATIONS: In this international study comparing adherence to quality care metrics for the quality of care for locoregional PCa, we identified regional variance, possibly because of regional differences in cultural attitudes and health care structures. These benchmarks highlight opportunities for interventions to improve adherence to evidence-based guidelines. PATIENT SUMMARY: Our study shows that adherence to recommended management goals for patients with prostate cancer varies greatly by global region.

Watchful Waiting Phase As Window of Opportunities for Non-pharmaceutical and Non-surgical Management of a Small Splenic Cyst Complicated With Thrombocytopenia.

An asymptomatic splenic cyst smaller than 50 mm was detected incidentally at a routine health checkup. Management of the cyst, affected and determined by multiple factors, including force majeure, became difficult and thrombocytopenia developed during watchful waiting. Spontaneous recovery of the spleen did not occur with continued watchful waiting, and thrombocytopenia worsened. However, when a three-month dietary intervention was subsequently implemented, the initiation of recovery was observed. The diet modification was adding to regular meals a daily serving of vegetables prepared following traditional Chinese culinary style. A second course of dietary intervention was undertaken, and accelerated recovery was detected thereafter, with eventual complete resolution of the splenic cyst and thrombocytopenia. This case demonstrates the feasibility and potential benefits of lifestyle intervention for the management of small splenic cysts, including those complicated with thrombocytopenia. Lifestyle intervention, such as dietary intervention, is particularly suitable for the watchful waiting phase since disease management during this time is non-pharmaceutical and non-surgical by nature.

The influence of nursing team's behavior in adverse event following immunization surveillance / Influencia del comportamiento del equipo de enfermería en la vigilancia de eventos adversos posvacunación / A influência das condutas da equipe de enfermagem na vigilância de eventos adversos pós-vacinação

ABSTRACT Objectives: to analyze the effects of nursing professionals' behavior in adverse event following immunization surveillance. Methods: a cross-sectional study of 384 participants who received vaccines. Information on vaccination history, administered vaccines and vaccination guidelines were analyzed. Descriptive and bivariate analyzes were performed using simple logistic regression (unadjusted Odds Ratio). Results: guidelines on events (PR=1.8; p=0.001) and conducts regarding their occurrence (PR=1.7; p=0.001) are activities that influence adverse event following immunization surveillance. More than half of participants did not receive guidance on the vaccines administered, the events and the conduct in case of an occurrence. Only 38.5% were instructed about the vaccines administered and 40.6% about adverse events. In the presence of an event, 29.9% reported that they sought services for notification. Conclusions: proper screening, providing guidance on vaccines and adverse events are essential preventive measures to strengthen adverse event following immunization surveillance.

The role of magnetic resonance imaging in active surveillance of prostate cancer / O papel da ressonância magnética na vigilância ativa do câncer de próstata

Abstract Active surveillance (AS) is an important strategy to avoid overtreatment of prostate cancer (PCa) and has become the standard of care for low-risk patients. The role of magnetic resonance imaging (MRI) in AS has expanded due to its ability to risk stratify patients with suspected or known PCa, and MRI has become an integral part of the AS protocols at various institutions. A negative pre-biopsy MRI result is associated with a very high negative predictive value for a Gleason score ≥ 3+4. A positive MRI result in men who are otherwise eligible for AS has been shown to be associated with the presence of high-grade PCa and therefore with ineligibility. In addition, MRI can be used to guide and determine the timing of per-protocol biopsy during AS. However, there are several MRI-related issues that remain unresolved, including the lack of a consensus and guidelines; concerns about gadolinium deposition in various tissues; and increased demand for higher efficiency and productivity. Similarly, the need for the combined use of targeted and systematic sampling is still a matter of debate when lesions are visible on MRI. Here, we review the current AS guidelines, as well as the accepted roles of MRI in patient selection and monitoring, the potential uses of MRI that are still in question, and the limitations of the method.

Resumo A vigilância ativa (VA) é uma estratégia importante para evitar o tratamento excessivo do câncer de próstata (CaP) e tornou-se o padrão de atendimento a pacientes de baixo risco. O papel da ressonância magnética (RM) na VA tem se expandido, devido à sua capacidade de estratificar o risco pacientes com CaP suspeito ou diagnosticado, tornando-se parte integrante dos protocolos de VA em várias instituições. Uma RM pré-biópsia negativa está associada a um valor preditivo negativo muito alto para o diagnóstico de Gleason ≥ 3+4. Um exame positivo em homens que são elegíveis para VA tem se mostrado associado à presença de CaP de alto grau e inelegibilidade para VA. A RM também pode ser usada para orientar e determinar o tempo ideal de uma biópsia, ou por protocolo, durante a VA. Há, no entanto, várias questões relacionadas à RM que permanecem não resolvidas. Estas incluem a falta de consenso ou diretrizes, preocupações com o depósito de gadolínio em vários tecidos e aumento da pressão por maior eficiência e produção. Da mesma forma, a necessidade de biópsia sistemática combinada à dirigida continua a ser uma questão controversa, quando as lesões são visíveis na RM. Revisaremos as atuais diretrizes de VA, os papéis consensualmente aceitos da RM na seleção e monitoramento dos pacientes, potenciais usos, ainda discutíveis, e as limitações do método.

Disforia de género en niños y controversias en su tratamiento: dos concepciones distintas sobre la identidad de género / Disforia de gênero em crianças e controvérsias em seu tratamento: duas concepções diferentes sobre a identidade de gênero / Gender Dysphoria in Children and Controversies about its Treatment: Two Different Conceptions of Gender Identity

Resumen La disforia de género es una marcada incongruencia entre el sexo que se siente o expresa y el que se asigna al nacer, asociada a un malestar clínicamente significativo o deterioro en lo social, que puede darse en niños, adolescentes y adultos. En relación con los pacientes pediátricos, no existe actualmente consenso sobre su tratamiento, así como tampoco evidencia que apoye claramente un enfoque por sobre otro. En la literatura se describen principalmente tres tipos de abordaje en niños preadolescentes: modelo terapéutico, watchful waiting (espera atenta) y modelo afirmativo. En este trabajo se realiza una breve revisión de la literatura existente sobre la disforia de género, se describen los distintos abordajes en niños y se analizan las visiones antropológicas que los sustentan. Plantearemos que existen al menos dos modos de entender la identidad de género, lo que ha dado lugar, en gran medida, a las controversias en los tratamientos propuestos. Por ello, resulta de gran importancia comprender los supuestos antropológicos en que se fundamentan estos modelos, ya que a cada uno de ellos subyacen diferentes maneras de entender la relación sexo-género en la persona y, por tanto, el rol de la corporalidad y de la autoconsciencia en la identidad de género.

Abstract Gender dysphoria is a marked mismatch between the sex felt or expressed by an individual and that assigned to them at birth. It is associated with clinically significant discomfort or social impairment and can occur in children, adolescents, and adults. The literature mainly describes three approaches for preadolescents: therapeutic model, watchful waiting, and gender affirmative model. However, there is currently no consensus on its treatment nor any evidence that favors one approach over another. This paper provides a brief review of the existing literature on gender dysphoria, explains various approaches for children, and discusses the anthropological views behind them. We argue that at least two ways of understanding gender identity have given rise to disagreements over the proposed treatments. It is quite important to comprehend the anthropological assumptions on which these models are based since they underlie different conceptions of the person's sex-gender relationship and, therefore, the role of corporality and self-awareness in gender identity.

Resumo A disforia de gênero é uma marcada incongruência entre o sexo que se sente ou expressa e o que é designado ao nascer, associada a um malestar clinicamente significativo ou a uma deterioração no âmbito social, que pode ocorrer em crianças, adolescentes e adultos. Quanto aos pacientes pediátricos, não existe atualmente consenso em seu tratamento nem evidência que apoie com clareza uma abordagem sobre outro. Na literatura, são descritos três tipos de abordagem em crianças pré-adolescentes: modelo terapêutico, watchful waiting (observação vigilante) e modelo afirmativo. Neste trabalho, é realizada uma breve revisão da literatura sobre a disforia de gênero, são descritas as diferentes abordagens em crianças e são analisadas as visões antropológicas que as justificam. É provável que haja, pelo menos, dois modos de entender a identidade gênero, o que abre espaço a controvérsias nos tratamentos propostos. Por isso, é de grande importância compreender os pressupostos antropológicos nos quais esses modelos estão fundamentados, já que a cada um deles subjazem diferentes maneiras de entender a relação sexo-gênero na pessoa e, portanto, o papel da corporeidade e da autoconsciência na identidade de gênero.
