Evaluation of Fine Needle Biopsy (FNB) for Endoscopic Ultrasound (EUS)-guided tissue acquisition of pancreatic masses to negate the need for rapid on-site evaluation: A randomized control trial

Background and Objectives@#The benefits of rapid on-site evaluation (ROSE) of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of solid masses have not been convincingly shown in large, randomized trials. New equipment using EUS-guided fine needle biopsy (FNB) allows for more material to be acquired that may obviate the need for ROSE. This study aimed to evaluate if EUS-FNB without ROSE was non-inferior to EUS-FNA with ROSE in solid pancreatic masses (SPMs). @*Methods@#Patients with SPMs requiring tissue sampling were randomly assigned to undergo either EUS-FNA with ROSE or EUS-FNB without ROSE. The touch-imprint cytology technique was used to perform ROSE. The primary endpoint was diagnostic accuracy and secondary endpoints were specimen quality, complication rates, and procedure time. @*Results@#Seventy-eight patients were randomized and analyzed (39 EUS-FNA with ROSE and 39 EUS-FNB without ROSE). Non-significantly different diagnostic accuracies were noted in both groups (97% with ROSE and 100% without ROSE, P < 0.371). The bloodiness of histologic samples and complication rates were not significantly different between groups. A significantly shorter mean sampling procedural time was noted for EUS-FNB over EUS-FNA with ROSE (30.4 ± 10.4 vs 35.8 ± 9.8 minutes, P < .02). @*Conclusions@#EUS-FNB demonstrated equal diagnostic accuracy with shorter procedure times in evaluating SPMs compared to EUS-FNA with ROSE. These new-generation FNB needles may obviate the need for ROSE.

Embarazo y tumor anexial: tratamiento laparoscópico con minilaparotomía. Reporte de caso y revisión bibliográfica / Pregnancy and annexal mass; laparoscopic with minilaparotomy management. Case report and literature review

Resumen ANTECEDENTES: Los tumores anexiales durante el embarazo requieren una conducta terapéutica segura para la madre y el feto, por lo que el obstetra debe tener claro cuándo la opción quirúrgica es la indicada y cuál la menos agresiva para la madre y el feto. Describir la implementación de la laparoscopia con minilaparotomía en un caso de tumor anexial en el embarazo puede contribuir a conocer las ventajas y desventajas de la estrategia quirúrgica de estos casos. CASO CLÍNICO: Paciente de 29 años, 70 kg de peso, talla de 1.61 m e IMC 27 en curso de las 16 semanas de embarazo, que acudió al servicio de Urgencias debido a un dolor abdominal. Ante la persistencia del síntoma se estableció el diagnóstico de síndrome doloroso abdominal, secundario a un tumor anexial gigante. Se programó para una laparoscopia diagnóstica y operatoria con minilaparotomía. Se dio de alta del hospital a las 24 horas posteriores a la cirugía y el embarazo finalizó a las 39 semanas. METODOLOGÍA: Búsqueda retrospectiva de artículos publicados durante los últimos diez años e indizados en la base de PubMed con los MeSH: adnexal masses pregnancy, adnexal masses pregnancy and laparoscopic surgery. RESULTADOS: Se incluyeron 34 artículos de revisión, 8 reportes de caso y un editorial, estos últimos 9 se consideraron cuando proveyeron información relevante para el conocimiento de una técnica quirúrgica. Se eliminaron los artículos en los que se utilizó cirugía asistida por robot o técnica con uso de orificios naturales (NOTES), revisiones que fueran exclusivas de patología oncológica, así como casos en niñas, al no disponer de esta tecnología en nuestro medio o no estar en etapa reproductiva, podría incurrirse en un riesgo de transferencia. Así mismo, se eliminaron los artículos sin explicación de las ventajas de la técnica propuesta. CONCLUSIÓN: En pacientes embarazadas con tumor anexial gigante, la laparoscopia con minilaparotomía es una opción de tratamiento segura para el feto y la madre. Con esta técnica se consigue una rápida recuperación, disminución de los riesgos de lesión uterina, pronta reintegración a la vida cotidiana y un buen desenlace cosmético.

Abstract BACKGROUND: Adnexal tumors during pregnancy require safe therapeutic behavior for the mother and the fetus, so the obstetrician must be clear when the surgical option is indicated and within the approach which would be less aggressive for the fetal-maternal binomial. Describing the implementation of laparoscopy with mini laparotomy in a case of adnexal tumor in pregnancy can contribute to understanding the advantages and disadvantages of the surgical strategy in these cases. CLINICAL CASE: Patient aged 29 years, weight 70 kg, height 1.61 m and BMI 27 in the course of 16 weeks of pregnancy, who attended the emergency department due to abdominal pain. Given the persistence of the symptom, a diagnosis of painful abdominal syndrome secondary to a giant adnexal tumour was established. She was scheduled for diagnostic and operative laparoscopy with mini-laparotomy. She was discharged from hospital 24 hours after surgery and the pregnancy ended at 39 weeks. METHODOLOGY: A literature search of the last 10 years was performed in Pubmed under the MeSH terms: adnexal masses pregnancy, adnexal masses pregnancy and laparoscopic surgery. RESULTS: Thirty-four review articles, eight case reports and one editorial were included, the latter nine were considered when they provided information relevant to the knowledge of a surgical technique. We eliminated articles in which robot-assisted surgery or a technique using natural orifices (NOTES) was used, reviews that were exclusive to oncological pathology, as well as cases in girls, as this technology was not available in our environment or they were not in the reproductive stage, which could incur a risk of transfer. Likewise, articles that did not explain the advantages of the proposed technique were eliminated. CONCLUSION: In pregnant patients with giant adnexal tumours, laparoscopy with mini-laparotomy is a safe treatment option for the foetus and the mother. This technique achieves a rapid recovery, reduced risk of uterine injury, early reintegration into daily life and a good cosmetic outcome.

Comparison of diagnostic performance of Clear Cell Likelihood Score v1.0 and v2.0 for clear renal cell carcinoma / 南方医科大学学报

OBJECTIVE@#To compare the performance of Clear Cell Likelihood Score (ccLS) v1.0 and v2.0 in diagnosing clear cell renal cell carcinoma (ccRCC) from small renal masses (SRM).@*METHODS@#We retrospectively analyzed the clinical data and MR images of patients with pathologically confirmed solid SRM from the First Medical Center of the Chinese PLA General Hospital between January 1, 2018, and December 31, 2021, and from Beijing Friendship Hospital of Capital Medical University and Peking University First Hospital between January 1, 2019 and May 17, 2021. Six abdominal radiologists were trained for use of the ccLS algorithm and scored independently using ccLS v1.0 and ccLS v2.0. Random- effects logistic regression modeling was used to generate plot receiver operating characteristic curves (ROC) to evaluate the diagnostic performance of ccLS v1.0 and ccLS v2.0 for ccRCC, and the area under curve (AUC) of these two scoring systems were compared using the DeLong's test. Weighted Kappa test was used to evaluate the interobserver agreement of the ccLS score, and differences in the weighted Kappa coefficients was compared using the Gwet consistency coefficient.@*RESULTS@#In total, 691 patients (491 males, 200 females; mean age, 54 ± 12 years) with 700 renal masses were included in this study. The pooled accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ccLS v1.0 for diagnosing ccRCC were 77.1%, 76.8%, 77.7%, 90.2%, and 55.7%, as compared with 80.9%, 79.3%, 85.1%, 93.4%, 60.6% with ccLS v2.0, respectively. The AUC of ccLS v2.0 was significantly higher than that of ccLS v1.0 for diagnosis of ccRCC (0.897 vs 0.859; P < 0.01). The interobserver agreement did not differ significantly between ccLS v1.0 and ccLS v2.0 (0.56 vs 0.60; P > 0.05).@*CONCLUSION@#ccLS v2.0 has better performance for diagnosing ccRCC than ccLS v1.0 and can be considered for use to assist radiologists with their routine diagnostic tasks.

Professor SUN Weizheng's Experience in Diagnosing and Treating Multiple Myeloma with the Clearing-Releasing Therapy / 中医杂志

The article summarized professor SUN Weizheng's clinical experience in treating multiple myeloma using the clearing-releasing therapy. It is believed that the mechanism of multiple myeloma is kidney essence insufficiency， pathogenic toxin erosion， and blinding of phlegm and stasis. The treatment should consider both the deficiency and the excess， and the root and branch. Thus， the clearing-releasing therapy is proposed. “Clearing” refers to the approach of supplementing deficiency and reinforcing health while advocating the use of clearing and supplementing products to replenish without generating additional pathogenic factors. Additionally， products that clear heat， resolve toxins， dispel stasis， dissolve phlegm， and eliminate masses is suggested to benefit for clearing away pathogenic toxins. “Releasing” means to replenish the normal yang qi with sweet-warm and acrid-warm products on the basis of “clearing” method， and to release the cold pathogen constraint in the muscles and bones. Based on the principle of clearing and releasing， the selfmade Jishi Beverage （济世饮） is formulated to supplement the kidney and secure essence， dispel phlegm and dissolve stasis， resolve toxins and dissipate masses. The prescription can be modified according to syndrome differentiation. It is also advocated to use multiple methods and pay attention to external therapies such as enema for relieving constipation and draining heat， and to combine acupuncture and medicine to relieve pain.

Value of MRI Ovarian-Adnexal Reporting and Data System in Differentiating Benign and Malignant Ovarian-Adnexal Lesions / 中山大学学报(医学科学版)

ObjectiveTo explore the value of MRI ovarian-adnexal reporting and data system （O-RADS MRI） in differentiating benign and malignant ovarian-adnexal masses.MethodsTotally 146 patients （202 masses） with ovarian-adnexal lesions who underwent pelvic examination at 3.0 T MRI according to standardized scan protocol of O-RADS MRI and were pathologically confirmed in The First Affiliated Hospital of Sun Yat-sen University between January 2020 and February 2022 were retrospectively analyzed. Two radiologists classified the ovarian-adnexal masses as risk levels 1~5 according to O-RADS MRI and evaluated their consistency by Cohen’s kappa. Using pathological findings as the gold standard， the detection yield of malignant lesions with O-RADS MRI classification was analyzed. Sensitivity， specificity， accuracy， and the area under the receiver operating characteristic curve were calculated （cutoff for malignancy， score ≥ 4）.ResultsOf 202 masses， 62 （30.7%） were malignant， 140 （69.3%） were benign. The two radiologists presented good agreement in O-RADS MRI classification of ovarian adnexal masses （Kappa=0.932）. The malignancy rates of masses with scores of 1， 2， 3， 4 and 5 were 0%， 0%， 7.7%， 95%， 97.6%， respectively. Sensitivity， specificity， accuracy， and the area under the receiver operating characteristic curve were 96.8% （60/62）， 98.6% （138/140）， 98.0% （198/202）， 0.977.ConclusionsO-RADS MRI yields high diagnostic efficiency for benign and malignant ovarian adnexal masses and its widespread implementation will improve communication between radiologists and clinicians， and facilitate optimal patient management. Therefore， O-RADS MRI warrants widespread use in clinical setting.

Lipoma cardiaco / Cardiac masses

Resumen Las masas cardiacas son entidades raras que cursan con un espectro muy variado de manifestaciones clínicas que van desde cuadros asintomáticos hasta compromiso hemodinámico severo. Entre las lesiones benignas, los lipomas cardiacos son los segundos en frecuencia. Corresponden principalmente a lesiones neoplásicas benignas; no obstante, se pueden presentar otras patologías como trombos, vegetaciones y variantes de la normalidad. Gracias a la disponibilidad de técnicas de imagen de alta definición, como la ecocardiografía, la TC y la RM, ha aumentado su detección y tratamiento temprano. En el ámbito terapéutico se ofrece manejo quirúrgico, pues las imágenes no permiten la caracterización y diferenciación fidedigna de la naturaleza de las masas cardiacas. Se describe el caso de una paciente sin antecedentes cardiovasculares, con historial de disnea crónica, en quien se identificó, a través de estudios imagenológicos, masa cardiaca adosada al ventrículo con deformación leve de cavidades derechas. Fue llevada a resección quirúrgica y por histopatología se confirmó lipoma. Este hallazgo es el más infrecuente de todos los tumores cardíacos benignos. Se resalta la importancia del conocimiento de esta enfermedad para dar tratamiento eficaz y oportuno en aras de evitar complicaciones que impacten en morbimortalidad.

Abstract Cardiac masses are rare entities that present with a very varied spectrum of clinical manifestations that go from asymptomatic to pictures with severe hemodynamic compromise, within these, cardiac lipomas are the second in frequency within benign lesions. They mainly correspond to benign neoplastic lesions, however, other pathologies such as thrombi, vegetations and variants of normality can occur. Thanks to the availability of high-definition imaging techniques, echocardiography, CT and MRI have increased early detection and treatment. In the therapeutic field, surgical management is offered, since the images do not allow the characterization and reliable differentiation of the nature of cardia masses. It is described the case of a patient with no cardiovascular history, with chronic dyspnea, in whom the presence of CM attached to the ventricle with slight deformation of the right cavities is identified by imaging studies. Was taken to surgical resection confirming the presence of lipoma by histopathology, being this finding the rarest of all benign cardiac tumors. We highlight the importance of knowing this pathology to provide effective and timely treatment to avoid complications that impact morbidity and mortality.

Cardiac atrial masses after a heart transplant. An array of differential diagnoses / Masas auriculares cardíacas tras un trasplante cardíaco. Una serie de diagnósticos diferenciales

Abstract Cardiac masses represent a heterogeneous group, including secondary malignancies as the most common ones, followed by primary tumors, vegetations, and thrombi. Cardiac imaging techniques are essential for the non-invasive diagnosis of cardiac masses. Thrombi in a transplanted heart, especially in atria, are very common, but when they appear as multiple, they could be an early sign of rejection. We present the case of a cardiac transplant patient who presented with masses in both atria and the left ventricle, as well as symptoms of right heart failure. Various image techniques were useful in establishing the differential diagnoses and appropriate treatment.

Resumen Las masas intracardíacas representan un grupo variado, que incluye metástasis como las más frecuentes, seguidas de tumores primarios, vegetaciones y trombos. Los trombos intracavitarios en un paciente trasplantado, especialmente en la aurícula, son muy frecuentes, pero, si aparecen como masas múltiples, pueden ser un dato precoz de un posible rechazo. Se expone el caso de un paciente trasplantado cardíaco que se presenta con masas intracavitarias en ambas aurículas y en el ventrículo izquierdo y datos de insuficiencia cardíaca de predominio derecho. Gracias al uso de varias técnicas de imagen se estableció el diagnóstico diferencial de las mismas, y se instauró el tratamiento adecuado.

Induction of somatic embryogenesis in Tecomella undulata (Sm.) Seem using a pistillate explant

Desert teak (Tecomella undulata (Sm.) Seem) a multipurpose ornamental tree native to the arid and semi-arid tropics has entered the endangered plant category mainly as a result of the species' ineffective seed reproduction system. The tree usually reproduces through a few root suckers in old stands. Conventional methods of plants multiplication could not offer a viable practice for its mass multiplication. Low adventitious rooting of the cuttings has been the principal cause of failure in its vegetative propagation. Hence, the present research was planned and conducted to evaluate the feasibility of somatic embryogenesis in this species, the pathway that bypasses the need for rooting stage by developing bipolar embryos. Ovary explant was cultured in modified Murashigue & Skoog (MS) medium supplemented with different auxins and cytokinins. The results showed ?-naphthalene acetic acid (NAA) was superior in inducing embryogenic callus. NAA ranging 5.4-21.5 ?M could induce the highest embryogenic calli which exhibited developing pro-embryogenic masses (PEM) and globular somatic embryos. The calli which were induced by the use of 2,4-dichlorophenoxyacetic acid (2,4-D) were poor in quality and showed no morphogenesis potency. Individual application of Thidiazuron (TDZ) and N6-benzyladenine (BA) induced good callogenesis at low concentrations but the calli were non-embryogenic with both. The proliferation of embryogenic calli was the best in a hormone-free medium. However, the media containing 40.5 and 54 ?M NAA alone could induce somatic embryos along with callus proliferation. Low BA-contained medium (0.9-4.44 ?M) led to recurrent somatic embryogenesis. Neither BA and GA3, nor the elevating sucrose concentration could cause further development and maturation of the somatic embryos induced during previous stages (callogenesis and callus proliferation). More research is required to optimize the maturation stage. The findings of the present study can be useful for future studies in the micropropagation of this recalcitrant specieslationships in Indian mustard under heat stress and the differential remobilization efficiencies in the advanced breeding lines.

Laparoscopic Management Of Adnexal Mass

Background:Laparoscopy is a widely used procedure in gynecological cases both for diagnostic and operative procedures. It is recommended due to lesser hospital stay, less post operative pain and better panoramic vision. Aim of the study is to assess the effectiveness of laparoscopic intervention of adnexal masses with benign pathology in recent series of consecutive patient. The focus is on pathology findings, length of stay, operating time, complications and laparotomy conversion rate. Material And Methods: This was a prospective observational study conducted at tertiary care hospital in Department of Obstetrics & Gynaecology during period of 1stAugust 2018 to 31st July 2020.This study consists of 70 patients, who presented with symptoms like pain in abdomen, bleeding per vaginum, irregular menses, excessive white discharge, distension of abdomen, infertility visiting outdoor patient department either diagnosed clinically(sign and symptoms) or by ultrasonography of adnexal masses. Result:Maximumpatients in this study were in age group 21-30 years. Maximum patients(21.42%)were having simple cyst. Among laparoscopic procedure most common procedure was left ovarian cystectomy(38.57%). Mean operative duration was 40.78 min and average duration of hospital stay was 3 days. There were minimal peri-operative complications; commonest being postoperative fever. Conclusion:Ade quatesurgical skill, case selection, multi disciplinary team approach and expert laproscopic surgical team are imperative for good patient outcome. This study gives an overview of experience in favour of laproscopic management of benign adnexal mass

Computed Tomography (CT)guided Fine Needle Aspiration Cytology of Intrathoracic Lesions

Background: Diagnosis of intrathoracic masses is a difficult challenge for clinicians. The compact anatomical arrangement of the medias?num with diverse pathologies is usually encountered. The present study was done to determine the efficiency of computed tomography (CT) guided Fine-Needle Aspira?on Cytology (FNAC) in the evalua?on of various thoracic mass lesions Methods : A total of n=46 pa?ents presen?ng as intrathoracic mass lesions, confirmed on contrast-enhanced CT, were included in the study. A commercially available CT (Ingenuity 128 slices, Philips) was used for biopsy. All pa?ents were subjected to detailed clinical history and physical examina?on. Inves?ga?ons: Complete blood count, Erythrocyte sedimenta?on rate, bleeding ?me, clo?ng ?me, Prothrombin ?me, Ac?vated par?al thromboplas?n ?me, HIV and HbsAg, Chest X-ray postero Anterior view, and Lateral view done in all cases. Chest X-ray AP view and Ultrasound was done wherever needed. Plain and contrast CT was done in all cases before FNAC. Results: The posi?ve diagnos?c yield in our study is noted in 45 of the 46 pa?ents(97.82%); the posi?ve yield for malignancy was 89.13% (41 of 46 pa?ents), benign in8.69 % (4/46), and undiagnosed in 1/46 (2.17%). Out of 46, 40(86.96%) were parenchymal lesions and 6(13.04%) were medias?nal lesions. Out of 40 parenchymal lesions, 38/40(95%) were malignant, which consisted of 55.3% Squamous cell carcinoma, 28.9% Adenocarcinoma. Conclusion: FNAC is useful for obtaining samples for the diagnosis of focal pulmonary infec?ons, even in immunocompromised pa?ents, and planning appropriate chemotherapy op?ons in lung cancer and metasta?c lesions.CT-guided FNAC is an ini?al approach for the diagnosis of small pulmonary nodules of less than 20mm, aiding in early diagnosis and treatment interven?ons improving prognosis.

MRI-based Bosniak version 2019 for Ⅱ, ⅡF and Ⅲ cystic renal masses: improved interobserver agreement by subtraction imaging / 中华放射学杂志

Objective:To investigate the value of MR subtraction images in improving the interobserver agreement for Bosniak Ⅱ, ⅡF, and Ⅲ cystic renal masses (CRMs) with Bosniak classification version 2019.Methods:From January 2009 to August 2020, 323 patients (335 CRMs) with surgical pathology results and complete preoperative MRI examination (T 2WI, T 1WI precontrast images and enhanced MRI in corticomedullary, nephrographic, and excretory phases) were retrospectively collected in the First Medical Center of PLA General Hospital. The CRMs of Bosniak Ⅱ, ⅡF, and Ⅲ were selected and classified by 2 experienced genitourinary radiologists according to the Bosniak classification version 2019. The "Subtraction" function in the American GE ADW 4.4 workstation was used to perform subtraction images reconstruction on the enhanced images in the corticomedullary, nephrographic, and excretory phases. Blinded to pathologic information, the other 2 radiologists independently classified the enrolled CRM cases with and without subtraction MR images, respectively, with an interval of 1 month. Ultimately, by using weighted Kappa value, interobserver agreement was evaluated, and the differences in weighted Kappa value were compared using the Gwet coefficient. Results:A total of 187 patients with 187 CRMs were enrolled in the study. The results of the classification of Bosniak Ⅱ, ⅡF, and Ⅲ CRMs categorized by 2 radiologists without and with subtraction images showed that 119 and 141 cases were consistent, and 68 and 46 were inconsistent, respectively. The weighted Kappa value for interobserver agreement among two radiologists without and with subtraction MR images was 0.60 (95%CI 0.53-0.68) and 0.73 (95%CI 0.66-0.80), respectively. The interobserver agreement was higher with subtraction images than that without subtraction images ( t=-2.56, P=0.011). Conclusion:According to the MRI criteria of Bosniak classification version 2019, the interobserver agreement for Bosniak Ⅱ, ⅡF, and Ⅲ CRMs could be improved using subtraction MR images, which may facilitate the popularization and application of Bosniak classification version 2019.

Malignidad o no de las masas anexiales de gran tamaño. Reporte de caso / Malignancy or not of large adnexal masses. Case report

Resumen ANTECEDENTES: Una masa anexial es una prominencia de localización cercana, o relacionada con los órganos reproductores femeninos y sus tejidos circundantes. En la práctica clínica, las masas anexiales representan un dilema en cuanto a su diagnóstico y tratamiento. El diagnóstico suele ser fortuito, luego de un hallazgo en el examen ginecológico o en estudios de imagen. CASO CLÍNICO: Paciente de 29 años, con antecedentes de tres embarazos, dos partos y un aborto, sin comorbilidades asociadas. El último parto se registró en enero del 2021. Acudió a consulta debido a un cuadro de dolor en la parte inferior del abdomen, tipo cólico, de intensidad progresiva 7/10 en la escala visual análoga, irradiado a la zona lumbar, asociado con episodios eméticos, sin ningún otro síntoma, de una semana de evolución. Al ingreso a Urgencias sus condiciones generales se estimaron aceptables: hidratada, álgica, sin alteraciones cardiacas ni pulmonares, sin afectación neurológica ni adenopatías. CONCLUSIONES: Es importante individualizar cada caso, determinar las características ecográficas y llevar a cabo un tratamiento escalonado conforme a la respuesta clínica de las pacientes. La bibliografía y este reporte comprueban la utilidad de los nuevos índices propuestos por la IOTA para el cálculo del riesgo de malignidad de masas complejas anexiales. En este reporte de caso se logra observar una correcta relación entre la sospecha preoperatoria y el desenlace histológico final.

Abstract BACKGROUND: An adnexal mass is a prominence of location close to, or related to, the female reproductive organs and their surrounding tissues. In clinical practice, adnexal masses represent a diagnostic and treatment dilemma. Diagnosis is usually fortuitous, following a finding on gynecological examination or imaging studies. CLINICAL CASE: 29-year-old patient, with a history of three pregnancies, two deliveries and one miscarriage, with no associated comorbidities. The last delivery was recorded in January 2021. She came for consultation due to a picture of pain in the lower abdomen, colic type, of progressive intensity 7/10 on the visual analog scale, radiating to the lumbar area, associated with emetic episodes, without any other symptoms, of one week of evolution. On admission to the emergency department, her general condition was considered acceptable: hydrated, energetic, without no cardiac or pulmonary alterations, without neurological involvement or lymphadenopathies. CONCLUSIONS: It is important to individualize each case, determine the ultrasound characteristics and carry out a stepwise treatment according to the clinical response of the patients. The literature and this report prove the usefulness of the new indexes proposed by IOTA for the calculation of the risk of malignancy of complex adnexal masses. In this case report a correct relationship between preoperative suspicion and final histologic outcome is observed.

Narcisismo e Melancolia em Psicologia das Massas e Análise do Eu: aproximações / Narcissism and Melancholy in Group Psychology and the Analysis of the Ego: approximations / Narcisismo y Melancolía en Psicología de las Masas y Análisis del Yo: aproximaciones

Ao levar em conta a sua importância tanto metapsicológica quanto social, este artigo traça um itinerário das noções de narcisismo e melancolia no escopo de "Psicologia das Massas e Análise do Eu". Neste sentido, ao promover uma reconstituição do caminho que se inicia em "Introdução ao Narcisismo" e "Luto e Melancolia" até a reaparição desses conceitos no texto sobre a psicologia das massas, pretende lançar luz sobre os processos de idealização, identificação e introjeção que, de acordo com Freud, ladrilham uma continuidade entre sujeito e sociedade. Conclusivamente, aponta possíveis conexões entre a cisão do Eu, a servidão melancólica e as tentativas de reaver um narcisismo mediante a imersão nas massas hodiernas.

Taking into account both its metapsychological and social importance, this article traces an itinerary of the notions of narcissism and melancholy within the scope of Freud's "Group Psychology and the Analysis of the Ego". Therefore, through a reconstitution of the path that begins in "On Narcissism: an introduction" and "Mourning and Melancholia" until the reappearance of these concepts in the text about the psychology of the masses, it intends to shed some light on the processes of idealization, identification and introjection that, according to Freud, tile a continuous line between subject and society. In conclusive terms, the present work points out some possible connections between the splitting of the Ego, the melancholic servitude and the attempts to recover a narcissism upon the immersion in the contemporary masses.

Al tener en cuenta su importancia metapsicológica como social, este artículo traza un itinerario de las nociones de narcisismo y melancolía en "Psicología de las Masas y el Análisis del Yo". En este sentido, a través de una reconstitución del camino que comienza en "Introducción al Narcisismo" y "Luto y Melancolía" hasta la reaparición de estos conceptos en el texto sobre Psicología de las masas, se pretende discutir los procesos de idealización, identificación e introyección que, según Freud, enmarca una continuidad entre el sujeto y la sociedad. En conclusión, el presente trabajo señala algunas posibles conexiones entre la división del Yo, la servidumbre melancólica y los intentos de recuperar un narcisismo que se expande por la inmersión en las masas contemporáneas.

Curva de aprendizaje para el diagnóstico ecográfico específico de masas anexiales / Learning curve for the specific ultrasound diagnosis of adnexal masses

OBJETIVO: Determinar el tiempo que requiere una curva de aprendizaje para diagnóstico ecográfico específico histopatológico en masas anexiales basándonos en cálculos estadísticos no influidos por la prevalencia según diferentes grados de experiencia. MÉTODOS: Estudio observacional, descriptivo, transversal. Se estudiaron imágenes de 108 masas anexiales. La prueba estándar de oro fue el reporte histopatológico definitivo. Se comparó el rendimiento diagnóstico de 4 examinadores con la siguiente experiencia en diagnóstico ecográfico de patología anexial: A > 20 años, B ≤ 20 hasta > 10 años, C ≤ 10 hasta > 5 años y D ≤ 5 años, analizando solo imágenes y sin datos clínicos de las pacientes, para emitir un diagnóstico específico a libre escritura. RESULTADOS: Prevalencia de masas malignas 17,2 % (15/87). Nivel de confianza en los examinadores se consideró según falta de respuesta diagnóstica: alto (<6 %) con experiencia de más de 10 años y moderado a bajo ≤ 10 años. Examinadores con más de 5 años siempre mostraron likelihood ratio positivo mayor a 10, exactitud diagnóstica mayor a 90 % y Odds ratio diagnóstica mayor a 46, no así para examinador con menor tiempo de experiencia, quién presentó resultados con mala utilidad clínica. El cambio de probabilidad de acierto específico pre-test a post-test mejoró consistentemente con los años de experiencia. CONCLUSIÓN: Se necesitarían más de 10 años de experiencia con especial dedicación a ecografía ginecológica avanzada para un rendimiento diagnóstico específico deseado junto con alta confianza en ecografía de masas anexiales.

OBJECTIVE: To determine the time required for a learning curve of histopathological specific ultrasound diagnosis in adnexal masses based on statistical calculations not influenced by prevalence according to different degrees of experience. METHODS: Observational, descriptive, cross-sectional study. Images of 108 adnexal masses were studied. The gold standard test was the definitive histopathological report. The diagnostic performance of 4 examiners with the following experience in ultrasound diagnosis of adnexal pathology: A > 20 years, B ≤ 20 to > 10 years, C ≤ 10 to > 5 years and D ≤ 5 years was compared, analyzing only images and blinded of clinical data of the patients, to issue a specific diagnosis with free writing. RESULTS: Prevalence of malignant masses 17.2% (15/87). The level of confidence in the examiners was considered according to the lack of diagnostic response: high (<6%) with experience of more than 10 years and moderate to low ≤ 10 years. The examiners with more than 5 years always showed likelihood ratio positive greater than 10, diagnostic accuracy greater than 90% and diagnostic Odds ratio greater than 46, not so for the examiner with less experience time who presented results with little clinical utility. The change in specific probability from pre-test to post-test improved consistently with years of experience. CONCLUSION: More than 10 years of experience with special dedication to advanced gynecological ultrasound are probably needed for a desired specific diagnostic performance coupled with high confidence in adnexal mass ultrasound.

Massas anexiais: descrição e interpretação ultrassonográfica por IOTA / Adnexal masses: IOTA ultrasound description and interpretation

Este artigo visa apresentar ao médico ginecologista (clínico e/ou cirurgião), de forma prática, a normatização internacional da prática da ultrassonografia ginecológica para avaliação das massas anexiais. Desde 2000, o grupo europeu IOTA (International Ovarian Tumor Analysis) vem colhendo dados e difundindo conhecimento nessa área, de forma a padronizar o exame ultrassonográfico. Quais descritores ecográficos devem ser valorizados, como devem ser descritos e medidos, como aplicar o estudo Doppler e como interpretar a presença ou ausência desses descritores ecográficos na diferenciação das massas anexiais benignas de malignas, inferindo o risco de malignidade das massas, tudo isso está bem definido.(AU)

The main aim of this article is to present to gynecologists (clinicians and/or surgeons) the practical international gynecological ultrasound standardization for adnexal masses assessment. Since 2000, European group IOTA (International Ovarian Tumor Analysis) has been collecting data and disseminating knowledge in order to standardize ultrasound examination. It is already well-defined which ultrasound features should be described and measured, how power/color Doppler have to be applied and how the presence or absence of these features can differentiate benign from malign masses, inferring tumors malignancy risk.(AU)

A Study to Assess the Accurate Detection and Characterization of Liver Masses among Patients with Liver Lesions Admitted in a Tertiary Care Centre

A reliable affirmation and delineation of focal liver injuries is crucial for immaculate patient association. The commonly encountered liver masses on ultrasonography are simple liver cyst, haemangioma, metastasis, hepatocellular carcinoma etc. We wanted to assess the accurate detection and characterization of liver masses among patients with liver lesions. METHODSA prospective study was conducted among 60 patients with liver lesions, who had undergone both abdominal ultrasonography and computed tomography and correlation was done with histopathology (FNAC / FNAB) for confirmation. Ultrasonography of liver imaging was obtained with SIEMENS and Longitudinal (sagittal), transverse (horizontal), coronal and oblique planes were obtained by using 3.5 MHz frequency transducer. Triple-phase helical CT images of the liver were obtained with Siemens Emotion 16 slice MDCT machine with 5 mm collimation, 0.6 mm reconstruction interval, gantry rotation speed of 0.6 second, pitch of 1.375:1, 120 kV, and 600 mA. RESULTSLesions which were encountered in the given time span were hepatocellular carcinoma (20 %), metastasis (33.3 %), hydrated cyst (2 %), abscess (5 %), haemangioma (13.3 %), Gb carcinoma, cholangiocarcinoma and other (5 % each) and simple liver cysts (10 %). Among the metastases observed in the liver, 20 % cases were from colorectal malignancies, 20 % were from lung, 15 % from breast, 15 % from ovary, and 15 % were from oesophagus and 15 % were from stomach. The highest percentages of liver metastases were from colon and rectum followed by lungs, oesophagus and stomach, and breast and ovary. Our study showed an accuracy of 98 % in diagnosing various lesions by confirming these diagnoses using image guided FNAC / FNAB. CONCLUSIONSClinical diagnosis based on examination can be very inaccurate, radiological investigations using ultrasonography and computed tomography can help us to arrive at an accurate diagnosis most of the times. Image guided FNAC / FNAB can confirm / dispute radiological diagnosis. This shows excellent correlation between radiological diagnosis and histological diagnosis of various liver lesions.

Experience of management of abdominal cysts

Benign intra-abdominal cystic masses in children are rare and they have diverse etiopathogenesis, clinical presentation. The present study highlights the experience in the management of benign intra-abdominal cysts pertaining to the diverse etiologies associated with these lesions. The medical records of our hospital between November 2016 to November 2019 were retrospectively reviewed. Patients with cystic abdominal masses were studied with respect to less different clinical presentations, localization of masses, diagnostic tests, surgical aapproaches, histopathological examinations and outcome. Out of the 55 cases, most common lesion was a choledochal cyst. Miscellaneous diagnosis includes an omental cyst, urachal cyst and a pedunculated bile duct cyst. All the cystic lesions of the abdomen need to be considered as close differentials in clinical practice due to the common presentations and similar symptoms produced by these lesions. All the lesions were managed by exploratory laparotomy except two ovarian cysts which were managed with laparoscopic approach.

Imaging spectrum of renal masses on multi-slice computed tomography

Background: Multi-slice computed tomography (MSCT) is the mainstay for preoperative assessment of many complex renal masses in current clinical practice. Benign renal processes may simulate malignant renal tumors and could be defined correctly by CT. MSCT has also an important role in tumor staging. The purpose of this article is to understand the imaging spectrum of renal masses on MSCT and assess the usefulness of CT in surgical planning and management.Methods: Studied 500 patients with suspected renal lesions who underwent MSCT during the period July 2017 to July 2020 at state-of-art imaging center. CT imaging was done in those patients in whom clinical examination and ultrasonography (USG) revealed possibility of diagnosis of renal masses for further detailed evaluation and deciding management.Results: Out of 500 total subjects, the common age group in this study is 51 to 60 years (25%). Male preponderance (59%) was noted. The most common presentation was pain (84%) followed by lump (29.4%) and haematuria (17.8%). Malignant masses (51%) were more common followed by benign (39%) and inflammatory masses (10%) respectively. Renal cell carcinoma has more incidence (30%) followed by simple cyst (20%). Calcification (19.6%), perinephric extension (78%) and vascular invasion (21.5%) are more common in malignant masses. Conclusion: MSCT is the modality of choice for the diagnosis of renal masses and deciding management approach in current practice. Detection of tumoral spread, invasion of surrounding organs and vascular structure are better with CT. MSCT also has a role in postoperative follow-up of renal masses.

Role of cancer antigen-125 in diagnosing malignant adnexal masses: a prospective observational study

Background: Adnexal masses present a diagnostic and therapeutic dilemma across age-groups. This study aimed to evaluate the performance of cancer antigen-125 (CA-125) in distinguishing between benign and malignant adnexal masses.Methods: This was a prospective, observational, single tertiary-care center study, done in North India from January, 2011 till December, 2012. Serum CA-125 levels was obtained preoperatively in consecutive patients presenting with ultrasonography confirmed adnexal masses. The cut-off value between benign and malignant was taken as 35 IU/ml. Histopathological diagnosis was obtained in all patients.Results: A total of 126 patients presented with adnexal masses, of which 100 were enrolled (mean age: 37.5±14.4 years, range: 18-80 years). Most of the masses were benign 81% (malignant=19%). Dermoid cyst (25.9%) and endometriomas (21%) were the most common benign masses. Serous (21%) and mucinous cystadeno-carcinoma (15.8%) were the most common malignant masses, more often seen in elderly, married, parous and post-menopausal patients. Mean CA-125 levels were significantly higher in malignant masses (257.30 [105.68-408.92] versus 19.26 [16.53-22.00], p<0.001). Overall sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CA-125 for diagnosing malignant adnexal mass was 94.7%, 87.65%, 64.28%, 98.6%, and 88.91% respectively. The same was 100%, 85.1%, 54.5%, 100%, 87.3% in premenopausal and 85.7%, 100%, 100%, 93.3%, 95.2% in postmenopausal women respectively.Conclusion: Benign masses form the bulk of the adnexal masses in all age groups. CA-125 levels has high sensitivity and negative predictive value in premenopausal patients while as high specificity and positive predictive value in postmenopausal patients.

Practical recommendations for the management of benign adnexal masses / Recomendações práticas para o tratamento de massas anexiais benignas

Abstract Objective To performa comprehensive review to provide practical recommendations regarding the diagnosis and treatment of benign adnexal masses, as well as information for appropriate consent, regarding possible loss of the ovarian reserve. Methods A comprehensive review of the literature was performed to identify the most relevant data about this subject. Results In total, 48 studies addressed the necessary aspects of the review, and we described their epidemiology, diagnoses, treatment options with detailed techniques, and perspectives regarding future fertility. Conclusions Adnexal masses are extremely common. The application of diagnosis algorithms is mandatory to exclude malignancy. A great number of cases can bemanaged with surveillance. Surgery, when necessary, should be performed with adequate techniques. However, even in the hands of experienced surgeons, there is a significant decrease in ovarian reserves, especially in cases of endometriomas. There is an evident necessity of studies that focus on the long-term impact on fertility.
