RESUMEN
Introduction: Percutaneous kidney biopsy (KB) is crucial to the diagnosis and management of several renal pathologies. National data on native KB in pediatric patients are scarce. We aimed to review the demographic and clinical characteristics and histopathological patterns in children who underwent native percutaneous KB over 24 years. Methods: Retrospective observational study of patients undergoing native percutaneous KB in a pediatric nephrology unit between 1998 and 2021, comparing 3 periods: period 1 (1998-2005), period 2 (2006-2013), and period 3 (2014-2021). Results: We found that 228 KB were performed, 78 (34.2%) in period 1, 91 (39.9%) in period 2, and 59 (25.9%) in period 3. The median age at KB was 11 (7-14) years. The main indications for KB were nephrotic syndrome (NS) (42.9%), hematuria and/or non-nephrotic proteinuria (35.5%), and acute kidney injury (13.2%). Primary glomerulopathies were more frequent (67.1%), particularly minimal change disease (MCD) (25.4%), IgA nephropathy (12.7%), and mesangioproliferative glomerulonephritis (GN) (8.8%). Of the secondary glomerulopathies, lupus nephritis (LN) was the most prevalent (11.8%). In group 1, hematuria and/or non-nephrotic proteinuria were the main reasons for KB, as opposed to NS in groups 2 and 3 (p < 0.01). LN showed an increasing trend (period 1-3: 2.6%-5.3%) and focal segmental glomerular sclerosis (FSGS) showed a slight decreasing trend (period 1-3: 3.1%-1.8%), without statistical significance. Conclusions: The main indication for KB was NS, which increased over time, justifying the finding of MCD as main histological diagnosis. LN showed an increase in incidence over time, while FSGS cases did not increase.
RESUMO Introdução: A biópsia renal (BR) percutânea é fundamental para diagnóstico e manejo de diversas patologias renais. Dados nacionais sobre BR nativa em pacientes pediátricos são escassos. Nosso objetivo foi revisar características demográficas, clínicas e padrões histopatológicos em crianças submetidas a BR percutânea nativa ao longo de 24 anos. Métodos: Estudo observacional retrospectivo de pacientes submetidos a BR percutâneas nativas em unidade de nefrologia pediátrica entre 1998 e 2021, comparando três períodos: período 1 (1998-2005), período 2 (2006-2013), período 3 (2014-2021). Resultados: Constatamos que foram realizadas 228 BR, 78 (34,2%) no período 1, 91 (39,9%) no período 2, 59 (25,9%) no período 3. A idade mediana na BR foi 11 (7-14) anos. As principais indicações para BR foram síndrome nefrótica (SN) (42,9%), hematúria e/ou proteinúria não nefrótica (35,5%), lesão renal aguda (13,2%). Glomerulopatias primárias foram mais frequentes (67,1%), principalmente doença de lesão mínima (DLM) (25,4%), nefropatia por IgA (12,7%), glomerulonefrite mesangioproliferativa (GN) (8,8%). Das glomerulopatias secundárias, nefrite lúpica (NL) foi a mais prevalente (11,8%). No grupo 1, hematúria e/ou a proteinúria não nefrótica foram os principais motivos para BR, ao contrário da SN nos grupos 2 e 3 (p < 0,01). A NL apresentou tendência crescente (período 1-3: 2,6%-5,3%) e a glomeruloesclerose segmentar focal (GESF) apresentou leve tendência decrescente (período 1-3: 3,1%-1,8%), sem significância estatística. Conclusões: A principal indicação para BR foi SN, que aumentou ao longo do tempo, justificando o achado de DLM como principal diagnóstico histológico. A NL apresentou aumento na incidência ao longo do tempo, enquanto os casos de GESF não aumentaram.
RESUMEN
ABSTRACT Purpose: To create a nomogram to predict the absence of clinically significant prostate cancer (CSPCa) in males with non-suspicion multiparametric magnetic resonance imaging (mpMRI) undergoing prostate biopsy (PBx). Materials and Methods: We identified consecutive patients who underwent 3T mpMRI followed by PBx for suspicion of PCa or surveillance follow-up. All patients had Prostate Imaging Reporting and Data System score 1-2 (negative mpMRI). CSPCa was defined as Grade Group ≥2. Multivariate logistic regression analysis was performed via backward elimination. Discrimination was evaluated with area under the receiver operating characteristic (AUROC). Internal validation with 1,000x bootstrapping for estimating the optimism corrected AUROC. Results: Total 327 patients met inclusion criteria. The median (IQR) age and PSA density (PSAD) were 64 years (58-70) and 0.10 ng/mL2 (0.07-0.15), respectively. Biopsy history was as follows: 117 (36%) males were PBx-naive, 130 (40%) had previous negative PBx and 80 (24%) had previous positive PBx. The majority were White (65%); 6% of males self-reported Black. Overall, 44 (13%) patients were diagnosed with CSPCa on PBx. Black race, history of previous negative PBx and PSAD ≥0.15ng/mL2 were independent predictors for CSPCa on PBx and were included in the nomogram. The AUROC of the nomogram was 0.78 and the optimism corrected AUROC was 0.75. Conclusions: Our nomogram facilitates evaluating individual probability of CSPCa on PBx in males with PIRADS 1-2 mpMRI and may be used to identify those in whom PBx may be safely avoided. Black males have increased risk of CSPCa on PBx, even in the setting of PIRADS 1-2 mpMRI
RESUMEN
La enfermedad vascular porto-sinusoidal es una causa infrecuente de hipertensión portal no cirrótica, fue descrita recientemente y es poco diagnosticada por el desconocimiento entre los médicos. Se considera en casos de hipertensión portal clínicamente significativa, en ausencia de cirrosis. El diagnóstico se basa en los hallazgos de la biopsia. El pronóstico de la enfermedad es mejor que el de los pacientes cirróticos, y el tratamiento es similar al de la hipertensión portal y al de las complicaciones que presentan los pacientes con cirrosis. Se presenta el caso de una paciente con várices esofágicas con estudios de imágenes no compatibles con cirrosis y hallazgos específicos en la biopsia de enfermedad vascular porto-sinusoidal. Este caso muestra el ejercicio diagnóstico en un caso de enfermedad vascular porto-sinusoidal de una paciente de Colombia, así como el resultado de las intervenciones terapéuticas y la evolución en el tiempo.
Porto-sinusoidal vascular disease is an uncommon cause of non-cirrhotic portal hypertension. It was recently described and is rarely diagnosed due to lack of knowledge among doctors. It is considered in cases of clinically significant portal hypertension in the absence of cirrhosis, and the diagnosis is based on biopsy findings. The prognosis of the disease is better than that of cirrhotic patients, and the treatment is similar to that of portal hypertension, including the management of complications associated with cirrhosis. We present the case of a patient with esophageal varices, whose imaging studies were not compatible with cirrhosis, alongside specific biopsy findings of porto-sinusoidal vascular disease. This case illustrates the diagnostic process in a patient from Colombia with portosinusoidal vascular disease, as well as the outcomes of therapeutic interventions and the patient´s evolution over time.
RESUMEN
La mastitis linfocítica o mastitis diabética es una patología benigna rara, caracterizada por una inflamación fibrótica de la mama, causando gran preocupación por la simulación de un carcinoma. Está asociada por lo general a la diabetes tipo 2, aunque pueden presentarse en otras patologías autoinmunes y además en pacientes sin comorbilidades. Se presenta en caso clínico de una paciente joven sin comorbilidades que consulto en consultorio de patología mamaria por tumor mamario. Se realizó una biopsia percutánea por trucut con confirmación histológica de mastitis linfocítica, se realizó control cercano observándose remisión clínica e imagenológica de la lesión en 6 meses de seguimiento. Se presenta el caso a fin de recalcar la importancia del diagnóstico histológico percutáneo de la lesión para determinar la naturaliza de la misma, constatándose una patología benigna que no requiere resección, evitando así causar deformidades que podrían afectar psicológicamente a la paciente.
Lymphocytic mastitis or diabetic mastitis is a rare benign pathology, characterized by fibrotic inflammation of the breast, causing great concern due to the simulation of carcinoma. It is generally associated with type 2 diabetes, although it can occur in other autoimmune pathologies and also in patients without comorbidities. The clinical case of a young patient without comorbidities who consulted in the breast pathology clinic due to a breast tumor. A percutaneous trucut biopsy was performed with histological confirmation of lymphocytic mastitis, close control was performed, observing clinical and imaging remission of the lesion in 6 months of follow-up. The case is presented in order to emphasize the importance of percutaneous histological diagnosis of the lesion, to determine its nature, confirming a benign pathology that does not require resection, thus avoiding causing deformities that could psychologically affect the patient.

Introdução: os lipomas são as neoplasias benignas de origem mesenquimal mais comum, podendo acometer diversas partes do corpo, sendo a região maxilofacial, de fato, uma das menos frequentes. Clinicamente, manifestam-se como aumentos de volume de crescimento lento e circunscrito, de base séssil ou pediculada, superfície lisa e consistência macia e coloração amarelada. Os sítios intra-orais mais acometidos são a mucosa jugal e o vestíbulo bucal.Dentre suas variantes microscópicas mais comuns, estão o fibrolipoma, composto de um componente fibroso. No entanto, tais variações não afetam o prognóstico do seu tratamento, que deve ser realizado através da excisão conservadora da lesão. OBJETIVO: O presente trabalho tem como objetivo relatar um caso atípico de lipoma intra-oral. DESCRIÇÃO DO CASO: Paciente do sexo feminino, 67 anos, apresentou-se com aumento de volume em região de fundo de vestíbulo mandibular com evolução de, aproximadamente, 10 meses, indolor, com queixas de dificuldade no posicionamento da prótese dentária inferior. O diagnóstico inicial foi de lipoma, confirmado por análise anatomopatológica através de biópsia excisional da peça. Considerações finais: O tratamento de lipomas intra-orais preconizado pela literatura é a excisão local, obtida por meio da biópsia excisional, sendo uma solução eficaz e de baixa morbidade ao paciente(AU)
Introduction: lipomas are the most common benign neoplasms of mesenchymal origin, which can affect different parts of the body, with the maxillofacial region, in fact, one of the least frequent. Clinically, they manifest as slow-growing, circumscribed swellings, with a sessile or pedunculated base, smooth surface, soft consistency and yellowish color. The most affected intraoral sites are the buccal mucosa and the buccal vestibule. Among its most common microscopic variants are the fibrolipoma, composed of a fibrous component. However, such variations do not affect the prognosis of its treatment, which must be carried out through conservative excision of the lesion. OBJECTIVE: This study aims to report an atypical case of intraoral lipoma. CASE DESCRIPTION: A 67-yearold female patient presented with swelling in the bottom region of the mandibular vestibule with an evolution of approximately 10 months, painless, with complaints of difficulty in positioning the lower dental prosthesis. The initial diagnosis was lipoma, confirmed by anatomopathological analysis through excisional biopsy of the specimen. Final considerations: The treatment of intraoral lipomas recommended by the literature is local excision, obtained through excisional biopsy, being an effective solution with low morbidity for the patient(AU)

El conocimiento de la patología oral, y su correcto diagnóstico es fundamental en Odontología, puesto que un diagnóstico tardío, particularmente en casos de lesiones premalignas o malignas, pueden conducir a serias consecuencias para el paciente. El objetivo de este trabajo fue establecer la congruencia diagnóstica clínica - histopatológica de lesiones en cavidad oral en pacientes que asistieron a la Facultad de Odontología, Universidad de Costa Rica, y a quienes se les realizó biopsia de la lesión, durante el período 2016-2019. El estudio fue descriptivo y retrospectivo, basado en datos de reportes histopatológicos en la población mencionada, por presentar alguna lesión, de tejidos blandos o duros, en cavidad oral. La muestra estadística fue por conveniencia, no probabilística y no aleatoria. Las técnicas estadísticas utilizadas fueron descriptivas para el análisis de la información, el cual se basó en la distribución de frecuencias y cruce de variables. El procesamiento estadístico de los datos se diseñó en una base de datos creada en Excel. La muestra comprendió 160 reportes histopatológicos de los cuales se excluyeron 14. La edad promedio de los pacientes fue 42 años (rango 2 - 78 años). La proporción hombre: mujer correspondió 1:1.4, predominado el sexo femenino en 58,9 %. La congruencia del diagnóstico histopatológico con el diagnóstico clínico correspondió a 55,8 %. La congruencia de los diagnósticos demuestra el conocimiento del profesional en identificar la lesión clínicamente de forma correcta, lo que permite actuar en el momento preciso y confirmar la impresión clínica diagnóstica de una patología mediante el estudio histopatológico, el cual es el estándar oro. El problema radica en aquellos casos en que hay discrepancia diagnóstica, pues exige conocer los factores responsables de esta discrepancia, exige la búsqueda de soluciones y exige reforzar y redireccionar la formación académica del profesional y de los estudiantes para reconocer y describir estas lesiones.
Knowledge of oral pathology and its correct diagnosis is fundamental in Dentistry, since a late diagnosis, particularly in cases of premalignant or malignant lesions, can lead to serious consequences for the patient. The objective of this study was to establish the clinical- histopathological diagnostic consistency of lesions in the oral cavity in patients who attended the Faculty of Dentistry, Universidad de Costa Rica, and who underwent a biopsy of the lesion, during the period 2016-2019. The study was descriptive and retrospective, based on data from histopathological reports in the mentioned population, due to presenting some lesion, soft or hard tissue, in the oral cavity. The statistical sample was for convenience, non- probabilistic nor random. The statistical techniques used were descriptive for the analysis of the information, which was based on frequency distribution and crossing of variables. The statistical processing of the data was designed in a database created in Excel. The sample collects 160 histopathological reports, of which 14 were excluded. The average age of the patients was 42 years (range between 2 - 78 years old).The male:female ratio corresponded to 1:1.4, with a predominance of the female sex at 58.9 %.The congruence of the histopathological diagnosis with the clinical diagnosis corresponded to 55.8 %. Diagnostic consistency demonstrates knowledge of the professional in correctly identifying the lesion clinically, which allows acting at the precise moment and confirming the diagnostic clinical impression of the pathology via histopathological study which is the gold standard. The problem lies in those cases in which there is a diagnostic discrepancy, since it requires having knowledge of the underlying factors and therefore, requires searching for solutions, reinforcing and redirecting the academic training of professionals and students to recognize and describe these lesions.
RESUMEN
La biopsia en carcinoma escamoso de orofaringe es un paso fundamental para su diagnóstico, por lo que es relevante conocer los diferentes tipos de ésta. Actualmente, se reconocen 4 tipos de biopsia en este tipo de carcinoma, cada uno de las cuales presentan indicaciones específicas: Biopsia incisional, excisional, punción con aguja fina (PAF) y biopsia liquida. La más frecuente y recomendada es la biopsia incisional por su rapidez y poca morbilidad asociada. Tanto la biopsia excisional como la PAF se reservan para casos de metástasis cervical de primario desconocido dependiendo de la etapa del análisis del paciente en particular. Finalmente, existe un fuerte desarrollo de la biopsia liquida, especialmente mediante el estudio del biomarcador ctHPV-DNA, el cual al ser un marcador sensible y específico para este tipo de carcinoma puede cambiar el paradigma del diagnóstico en un futuro cercano.
Oropharyngeal squamous cell carcinoma biopsy is a fundamental step in the diagnosis; therefore, it is relevant to know its different types. Currently, four types of biopsy are recognized for this type of carcinoma, each of which has specific indications: incisional biopsy, excisional biopsy, fine needle aspiration (FNA), and liquid biopsy. The most frequent and recommended procedure is incisional biopsy, because of its speed and low associated morbidity. Both excisional biopsy and FNA are reserved for cases of cervical metastasis of unknown primary depending on the stage of analysis of the particular patient. Finally, there is a strong development in liquid biopsy, especially through the study of the ctHPV-DNA biomarker, which is a sensitive and specific marker for this type of carcinoma, and may change the diagnostic paradigm in the near future.
RESUMEN
Las manifestaciones cutáneas de los tumores malignos comprenden un grupo de dermatosis que pueden ser marcadores de la presencia de neoplasias ocultas y permiten su diagnóstico oportuno. El objetivo de este informe es presentar las características clínicas de una acantosis nigricans asociada a carcinoma de mamario. Para ello, se describe el caso clínico de una paciente de 50 años, color de piel negro, asistida en la consulta de Dermatología del Policlínico Universitario Raúl Sánchez, por tener una placa única eritematosa localizada en la mama izquierda, acompañada de dolor, aumento de la temperatura local y máculas hipercrómicas en las axilas; así como adenopatías axilares múltiples. Los exámenes complementarios mostraron la presencia de acantosis nigricans maligna asociada a un carcinoma inflamatorio de la mama izquierda. Fue intervenida quirúrgicamente, con la consiguiente desaparición de las lesiones cutáneas, pero con un pronóstico reservado. La mayoría de los síndromes paraneoplásicos son inespecíficos; existe una necesidad urgente de sospechar una correlación entre los cambios cutáneos y la posibilidad de una neoplasia interna, por lo que es de suma importancia derivar a estos pacientes para su identificación y el diagnóstico precoz de la enfermedad de base. Esto mejoraría el pronóstico y atenuaría en gran medida las consecuencias.
The skin manifestations of malignant tumors include a group of dermatoses that can be the sign of the occult neoplasms presence and allow their timely diagnosis. The objective of this report is to present the acanthosis nigricans' clinical characteristics associated with breast carcinoma. The clinical case of a 50-years-old black-skinned patient is described, assisted in the Dermatology consultation of the Raúl Sánchez University Polyclinic, for having a single erythematous plaque located in the left breast, accompanied by pain, increased local temperature and hyperchromic macules in the armpits; as well as multiple axillary lymphadenopathy. Complementary examinations showed the presence of malignant acanthosis nigricans associated with an inflammatory carcinoma of the left breast. She underwent surgery, with the consequent disappearance of the skin lesions, but with a reserved prognosis. Most paraneoplastic syndromes are nonspecific; there is an urgent need to suspect a correlation between skin changes and the possibility of an internal neoplasia, so it is of utmost importance to refer these patients for identification and early diagnosis of the underlying disease. This would improve the prognosis and greatly mitigate the consequences.
RESUMEN
RESUMEN Introducción: El cáncer hepático es la séptima neoplasia más frecuente a nivel mundial y la segunda causa de mortalidad asociada directamente a cáncer. En México presenta una incidencia del 3.9% en toda la población. A pesar de que la tomografía axial computada es el estudio diagnóstico inicial de elección, el diagnóstico final se establece con el estudio anatomopatológico de la lesión. Objetivo: Correlacionar los hallazgos tomográficos con el resultado histopatológico en pacientes con lesiones hepáticas con sospecha de malignidad, a los que se les tomó biopsia dirigida por USG. Material y métodos: Estudio descriptivo, de correlación, retrolectivo, homodémico y unicéntrico. El tiempo de estudio fue de septiembre 2021 a febrero 2022. Se seleccionó a pacientes mayores de 18 años con lesiones hepáticas sospechosas de malignidad, a los que se les realizó tomografía y biopsia guiada por ultrasonido. Se utilizó pruebas de Shapiro-Wilk (de normalidad) y se utilizó ꭕ2 para un análisis de asociación de variables categóricas. Resultados: Se incluyeron a 24 pacientes, a los cuales se les realizó tomografía y biopsia de lesión, encontrando un tamaño promedio de las lesiones de 2.39cm. Los resultados de la correlación entre el diagnóstico tomográfico y el diagnóstico histopatológico definitivo no tuvieron significancia estadística p=0.069. Conclusiones: No se encontró correlación significativa entre el estudio histopatológico y los hallazgos tomográficos en lesiones hepáticas sugerentes de malignidad.
ABSTRACT Introduction: Liver cancer is the seventh most common neoplasm worldwide and the second cause of mortality directly associated with cancer. In Mexico it has an incidence of 3.9% in the entire population. Although computed tomography (CT) is the imaging study of choice, the final diagnosis is established with the anatomopathological study of the lesion. Objective: Correlate the tomographic findings with the histopathological result in patients with liver lesions with suspicion of malignancy, who underwent USG-guided biopsy. Methods: Descriptive, correlation, retrolective, homodemographic and single-center study. The study period was from September 2021 to February 2022. Patients older than 18 years with liver lesions suspicious of malignancy were selected and underwent Computed Axial Tomography and ultrasound-guided biopsy. Shapiro Wilk tests (for normality) were used and chi-square was used for an analysis of association of categorical variables. Results: Twenty-four patients were included, who underwent Tomography and lesion biopsy, finding an average size of lesions of 2.39cm. The results of the correlation between the tomographic diagnosis and the definitive histopathological diagnosis did not have statistical significance p=0.069. Conclusions: No significant correlation was found between the histopathological study and tomographic findings in liver lesions suggestive of malignancy.
RESUMEN
Objectif: Le cancer du sein chez la femme jeune est rare etprésente des caractéristiques épidémiologiques, diagnostiques et pronostiques propres. L'objectif de notre étude est d'évaluerles caractéristiques radiologiques (mammographiques, échographiqueset par résonnancemagnétique IRM du cancer du sein chez la femme jeune Algérienne, de moins de 35 ans. Matériels etméthodes: Etude prospective, descriptiveau sein du service d'imagerie médicale du Centre Pierre et Marie Curie,d'Algerincluant 204patientes âgées de moins 35ans, étalée sur 3 ans allantentre janvier 2015et janvier 2017,chez lesquelles undiagnostic de cancer du sein a été porté,Elles ont toutes bénéficiésd'une mammographie numérique, d'une échographie et d'une IRM mammaireet d'unprélèvement percutané.Résultats:La fréquence du cancer du sein chez la femme jeune de moins de 35 ans était de 10,6%. L'âge moyen était de 30.9 ans. L'autopalpation d'un nodule était prédominante (87.2%). La densité mammaire était de type c et d dans 67.7%. Contrairement à l'idée établie, la mammographie avait permis souvent le diagnostic de ces tumeurs. A la mammographie, la répartition des cas selon le stade BI-RADS révèle que plus de la moitié (53.9%) était classée BI-RADS 5 ; 35.5 % des cas classés en BIRADS 4, 7.2% classés en BI-RADS 3 et un faible pourcentage (3.6 %) en BI-RADS 0. Pour l'échographie, la répartition des cas selon les stades BI-RADS révèle que plus de la moitié était classée ACR5, ce qui représente 64 %, 32.7 % classée en ACR4 et 3.3% en ACR3.A l'IRM, 71.1 % des cas ont été classés en ACR 5, 28.4% en ACR4 et 0.5 des cas en ACR 3. Le type histologique était de type carcinome canalaire infiltrant de grade III et II selon Scarff-Bloom et Richardson (SBR) dans 96.11% descas.Conclusion: L'expression radiologique est souvent non spécifique et évocatrice d'une lésion suspecte néanmoins nous avons constaté une plus grande fréquence de tumeurs d'allure bénigne en mammographie par rapport à l'échographie mammaire et à l'IRM mammaire. L'IRM mammaire reste donc utile dans la caractérisation lésionnelle et le bilan d'extension
Objective: Breast cancer in young women is rare and has its own epidemiological, diagnostic and prognostic features. The aim of our study was to evaluate the radiological (mammographic, ultrasonographic and MRI) characteristics of breast cancer iMaterials and methods: Prospective, descriptive study in the medical imaging department of the CPMC in Algiers, including 204 patients under 35 years of age, over a 3-year period from January 2017 to January 2020, diagnosed with breast cancer. They all underwent digital mammography, ultrasound and MRI of the breast and percutaneous sampling.Results: The incidence of breast cancer in young women under 35 was 10.6%. The mean age was 30.9 years. Autopalpation of a nodule was predominant (87.2%). Breast density was type c and d in 67.7%. Contrary to popular belief, these tumorswere often diagnosed by mammography. On mammography, the distribution of cases according to BIRADS stage revealed that over half (53.9%) were classified as BIRADS 5; 35.5% of cases classified as BIRADS 4, 7.2% classified as BIRADS 3 and a small percentage (3.6%) as BIRADS 0.On ultrasonography, the distribution of cases according to BIRADS staging revealed that over half were classified as ACR5, representing 64%, 32.7% as ACR4 and 3.3% as ACR3. On MRI, 71.1% of cases were classified as ACR 5, 28.4% as ACR4 and 0.5 of cases as ACR 3. Histological type was infiltrating ductal carcinoma grade III and II according to Scarff-Bloom and Richardson (SBR) in 96.11% of cases.Conclusion: Radiological expression is often non-specific and suggestive of a suspicious lesion. Nevertheless, we found a greater frequency of benign tumorsin mammography than in breast ultrasound and breast MRI. Breast MRI therefore remains useful for lesion characterization and extension assessmenn young Algerian women under 35 years of age.

Objectif.Depuis 2008, la Haute Autorité Sanitaire recommande la réalisation du scanner cardiaque dans le diagnostic des cardiopathies congénitales. Celui-ci aide à confirmer et préciser les anomalies mal définies à l'échocardiographie. Dans les pays développés, le scanner cardiaque est un examende routine pour le diagnostic des cardiopathies congénitales. En Côte-d'Ivoire, sa pratique est récente.L'objectif de cette étude était de décrire les techniques et résultats des scanners cardiaques pédiatriques réalisés dans une structure privée à Abidjan.Matériels et méthodes.Il s'agissait d'une étude descriptive rétrospective sur une période de 2 mois qui a inclus tous les enfants reçus à la clinique la rosette pour la réalisation d'un scanner cardiaque indiqué pour l'évaluation d'une cardiopathie congénitale. Les examens ont été réalisés sous sédation légère pour les enfants de moins de 7 ans.Résultats.Vingt scanners cardiaques pédiatriques ont été réalisés. Les indications des scanners cardiaques pédiatriques étaient la tétralogie de Fallot (15 cas), l'atrésie pulmonaire à septum ouvert (APSO) (2 cas), la communication inter auriculaire (CIA) (1 cas), la CIA associée à une communication interventriculaire (CIV) (1 cas) et la sténose pulmonaire supra valvulaire (1 cas). Dans les cas de Tétralogie deFallot et d'APSO, les branches pulmonaires et les collatérales aorto-pulmonaires ont été visualisées et mesurées. Pour le bilan de , un retour veineux pulmonaire non visualisé à l'échocardiographie a été retrouvé au scanner cardiaque. Dans tous les cas, un bilan tomodensitométrique malformatif était réalisé : recherche d'anomalies coronaires et d'arcs aortiques.Après réalisation du scanner cardiaque, 5 enfants ont bénéficié d'une cure chirurgicale. On notait une concordance entre les diagnostics peropératoires et tomodensitométriques
Objective. Since 2008, the French National Authority for Health recommends the use of a cardiac scanner for the diagnosis of congenital heart disease. It helps to confirm and clarify abnormalities that are poorly defined on echocardiography. In developed countries,cardiac CT is a routine examination for the diagnosis of congenital heart disease. In Côte d'Ivoire, its practice is recent. Materials and Methods. This was a retrospective descriptive study over a period of 2 months which included all children received at the Rosette clinic for a cardiac scan indicated for the evaluation of congenital heart disease. The examinations were performed under light sedation for children under 7 years of age. Results. Twenty paediatric cardiac scans were performed. The indications for the paediatric cardiac scans were tetralogy of Fallot (15 cases), pulmonary atresia with ventricular septal defect (PAVSD) (2 cases), atrial septal defect (ASD) (1 case), ASD associated with ventricular septal defect (VSD) (1 case) and supravalvular pulmonary stenosis (1 case). In cases of Tetralogy of Fallot and APSO, pulmonary arteries and aorto-pulmonary collaterals were visualised and measured. For the assessment of ASD, an anomalous pulmonary venous return not visualised on echocardiography was found on cardiac computed tomography (CT). In all cases, a malformative CT scan was performed: search for coronary, aortic arch. After the cardiac, 5 children underwent surgical treatment. There was concordance between the intraoperative and CT diagnoses. Conclusion. In our experience, cardiac CT now represents, minimally invasive, complementary diagnostic tool for the evaluation of congenital heart disease.

Objective To explore the effect and safety of magnetic resonance imaging and transrectal ultrasound (mpMRI-TRUS) image fusion targeted transperineal biopsy technique using electromagnetic needle tracking under local anesthesia. Methods We retrospectively analyzed the clinical and pathological data of 81 patients with mpMRI-TRUS image fusion targeted transperineal prostate biopsy using electromagnetic needle tracking under local anesthesia. Visual analog scale (VAS) and visual numeric scale (VNS) were used to evaluate the pain level and satisfaction of patients during prostate biopsy (VAS-1 and VNS-1), one hour after puncture (VAS-2 and VNS-2), and one day after surgery (VAS-3 and VNS-3). The perioperative clinical data and tumor positive rate of postoperative biopsy were recorded. Results The average prostate volume of 81 patients was 53.39±29.46 cm3. The PSA values of patients with PI-RADS scores of 2, 3, 4, and 5 were 9.14±2.31, 9.95±4.10, 14.77±6.36, and 32.17±24.39 ng/ml, respectively. The scores of VAS-1, VAS-2, and VAS-3 were 1.70±0.73, 1.16±0.58, and 0.53±0.55, respectively; the scores of VNS-1, VNS-2, and VNS-3 were 2.74±0.44, 3.69±0.46, and 3.84±0.37, respectively. The average surgical time was 17.47±3.44 minutes. Postoperative pathological results showed that the tumor positive rate of targeted prostate biopsy was 64.20%. According to the PI-RADS score for subgroup analysis, the tumor positive rates of patients with PI-RADS scores of 2, 3, 4, and 5 were 21.43%, 44.44%, 61.11%, and 96.77%, respectively. After transperineal prostate biopsy, gross hematuria occurred in 19.75% patients, and urinary retention occurred in 3.70%. The latter were relieved after symptomatic treatment. All patients did not experience complications, such as perineal puncture area hematoma, urinary tract infection, hematospermia, hematoma in perineal puncture area, urinary tract infection, hematospermia, vagus nerve reaction, or septic shock. Conclusion For suspected prostate cancer patients, mpMRI-TRUS image fusion targeted transperineal biopsy technique using electromagnetic needle tracking under local anesthesia is a feasible and easily tolerated surgical procedure. It has good safety and high tumor positive-detection rate, indicating that this technique is worthy of further clinical promotion and application.
RESUMEN
BACKGROUND@#The thoracic small biopsy sampling procedure including transbronchial forceps lung biopsy (TBLB) and endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) can be accompanied by rapid on-site evaluation (ROSE) of sample material to provide immediate feedback for the proceduralist. The present study aims to investigate the supplemental effect of ROSE smear samples for lung cancer molecular test.@*METHODS@#In a retrospective study, 308 patients admitted to our hospital from August 2020 to December 2022 undergoing diagnostic TBLB and EBUS-TBNA with ROSE and subsequently diagnosed as non-small cell lung cancer (NSCLC) were analyzed. The matched formalin-fixed paraffin-embedding (FFPE) tissue section and ROSE smears for tumor cellularity were compared. DNA yields of smears were determined. Real-time polymerase chain reaction (PCR) and next-generation sequencing (NGS) were performed on adequate smear samples.@*RESULTS@#ROSE smear samples were enriched in tumor cells. Among 308 biopsy samples, 78 cases (25.3%) exhibited inadequate FFPE tissue sections, whereas 44 cases (14.3%) yielded adequate smear samples. Somatic mutations detected in the FFPE tissue section samples were also detected in the matching adequate smear sample.@*CONCLUSIONS@#ROSE smear samples of the thoracic small biopsies are beneficial supplemental materials for ancillary testing of lung cancer. Combined use of cytology smear samples with traditional FFPE section samples can enhance the detection rate of informative mutations in patients with advanced NSCLC. We recommend that the laboratory could further evaluate the ROSE cell smears of the patient when FFPE tissue sections are inadequate, and that adequate cell smears can be used as a supplemental source for the molecular testing of NSCLC.

Objective:To investigate the application value of ultrasound-guided multimodal examinations in the diagnosis of lymph node mycobacterial infection.Methods:The clinical data of 42 patients with suspected lymph node mycobacterial infection who were initially diagnosed at the Affiliated Hospital of Shaoxing University from January 2019 to December 2020 were retrospectively analyzed. All patients underwent an ultrasound-guided lymph node-negative pressure puncture. Acid-fast staining, bacterial culture, pathological examination or their combination were used to screen lymph nodes for mycobacterial infection. The results were compared with those of acid-fast staining and bacterial culture of sputum and bronchoalveolar lavage fluid smears.Results:The combined application of acid fast staining, bacterial culture, and pathological examination for the puncture fluid smear showed a positive rate of 71.4% (30/42), which was significantly higher than the positive rate [26.2% (11/42)] for acid fast staining of the puncture fluid smear, the positive rate [42.9% (18/42)] for bacterial culture of the puncture fluid, and the positive rate [50.0% (21/42)] of pathological examination ( χ2 = 17.20, 7.00, 4.04, P < 0.001, P < 0.01, P = 0.040). The positive rate for sputum smear and bacterial culture was 21.4% (9/33). The positive rate for acid fast staining and bacterial culture of the bronchoalveolar lavage fluid was 28.6% (12/30). The differences were statistically significant ( χ2 = 21.11, 15.43, both P < 0.001). Conclusion:Ultrasound-guided negative pressure aspiration and puncture biopsy of lymph nodes combined with acid fast staining, bacterial culture, and pathological examinations can markedly increase the detection rate and diagnostic rate of mycobacterial infection.
RESUMEN
Objective:To assess the diagnostic utility of ultrasound-guided fine-needle aspiration (FNA) combined with BRAF V600E gene mutation detection for discerning benign from malignant thyroid isthmus nodules classified as thyroid imaging report and data system (TI-RADS) 4a and 4b. Methods:A retrospective analysis was conducted on the clinical data of 48 patients with thyroid nodules of TI-RADS 4, who underwent surgical confirmation and pathological diagnosis at Jiaozuo People's Hospital between October 2019 and June 2022. Using surgical and pathological outcomes as the gold standard, the diagnostic efficacy of FNA cytopathology, BRAF V600E gene mutation detection, and the combined approach were individually evaluated for benign and malignant thyroid nodules of TI-RADS 4. Results:The receiver operating characteristic curve analysis revealed the diagnostic values of FNA, BRAF V600E gene mutation detection, and their combined use in predicting the benignancy or malignancy of thyroid isthmus nodules. For TI-RADS 4a nodules, the areas under the curves were 0.876 for FNA, 0.852 for BRAF V600E gene mutation detection, and 0.952 for the combined approach. For TI-RADS 4b nodules, the areas under the curves were 0.850, 0.858, and 0.908, respectively. The P-values were 0.010, 0.016, and 0.002 for TI-RADS 4a nodules, and 0.006, 0.005, and 0.001 for TI-RADS 4b nodules. Notably, the combined approach demonstrated larger areas under the curves compared with individual applications. Conclusion:The combined use of FNA and BRAF V600E gene mutation detection enhances the diagnostic accuracy for thyroid isthmus nodules classified as TI-RADS 4a and 4b, as reflected by an increased area under the receiver operating characteristic curve.

RESUMEN
Objective To analyze the detection of helicobacter pylori(Hp)in different parts of gastric antrum,and to provide clinical guidance for finding the best biopsy site for Hp.Methods Patients who underwent 13C urea breath test and electronic gastroscopy from January 2020 to December 2022 were retrospectively analyzed and divided into 13C urea breath test positive group[delta over baseline(DOB)≥4]and 13C urea breath test negative group(DOB<4)according to DOB value.Gastroscopy reports and pathological data of patients were collected.According to different biopsy sites in gastric antrum,patients were divided into conventional biopsy site group,elevated erosive site group and flat erosive site group,and the detection rate of Hp in different biopsy sites was compared.13C urea breath test positive group was divided into group A(4<DOB≤16),group B(16<DOB≤35)and group C(DOB>35)according to DOB value,and the gastric antral biopsy and pathology of each group were classified and analyzed.Combined with endoscopic reports and pathological data,patients were divided into atrophic gastritis group and non-atrophic gastritis group.Results In the 13C urea breath test positive group,the detection rate of Hp in the elevated erosive site group(96.4%)was higher than that in the conventional biopsy site group(92.7%)and the flat erosive site group(93.9%),and the difference was statistically significant(P = 0.036).In DOB group A,the detection rate of Hp was the highest at the site of elevated erosive and the lowest at the site of conventional biopsy,and the detection rate of Hp at the three biopsy sites was compared,the difference was statistically significant(P = 0.016);There was no significant difference in the detection rate of Hp at three biopsy sites between group B and group C(P = 0.622;P = 0.721);the non-atrophic gastritis group,the detection rate of Hp at the elevated erosive site(96.5%)was higher than that at the conventional biopsy site(91.2%)and the flat erosive site(92.0%),and the difference was statistically significant(P = 0.043).There was no significant difference in the detection rate of Hp at three biopsy sites in the atrophic gastritis group(P = 0.614).13C urea breath test negative group:There was no significant difference in Hp detection rate among the three biopsy sites(P = 0.255).Conclusion For patients with positive 13C urea breath test but low DOB value,the positive rate of Hp in the elevated erosive site is higher.For non-atrophic gastritis patients,the detection rate of Hp was higher in the elevated erosive sites than in the conventional biopsy sites.But for patients with atrophic gastritis,there was little difference in the detection rate of Hp in different parts of antrum.For patients with negative 13C urea breath test,there was no significant difference in Hp detection rate among the three biopsy sites.In future clinical work,for similar patients,precise biopsy can be performed to improve the detection rate of Hp.
RESUMEN
Originating but free from chromosomal DNA, extrachromosomal circular DNAs (eccDNAs) are organized in circular form and have long been found in unicellular and multicellular eukaryotes. Their biogenesis and function are poorly understood as they are characterized by sequence homology with linear DNA, for which few detection methods are available. Recent advances in high-throughput sequencing technologies have revealed that eccDNAs play crucial roles in tumor formation, evolution, and drug resistance as well as aging, genomic diversity, and other biological processes, bringing it back to the research hotspot. Several mechanisms of eccDNA formation have been proposed, including the breakage-fusion-bridge (BFB) and translocation-deletion-amplification models. Gynecologic tumors and disorders of embryonic and fetal development are major threats to human reproductive health. The roles of eccDNAs in these pathological processes have been partially elucidated since the first discovery of eccDNA in pig sperm and the double minutes in ovarian cancer ascites. The present review summarized the research history, biogenesis, and currently available detection and analytical methods for eccDNAs and clarified their functions in gynecologic tumors and reproduction. We also proposed the application of eccDNAs as drug targets and liquid biopsy markers for prenatal diagnosis and the early detection, prognosis, and treatment of gynecologic tumors. This review lays theoretical foundations for future investigations into the complex regulatory networks of eccDNAs in vital physiological and pathological processes.

Cervical lymph node metastasis in thyroid cancer is closely related to the disease recurrence and prognosis of patients. Accurate judgment of lymph node metastasis is vital for tumor stage and treatment in patients with thyroid cancer, which can effectively improve the prognosis of patients. However, preoperative detection of cervical lymph node metastasis is the key points and difficulties in individualized treatment of thyroid cancer. Currently, fine needle aspiration washout fluid thyroglobulin is often used to assess cervical lymph node metastasis of differentiated thyroid cancer preoperatively, and it has a higher diagnostic efficacy. The continuous exploration and application of tumor markers and emerging biomarkers have provided new perspectives for the preoperative diagnosis of lymph node metastasis in thyroid cancer. As a new non-invasive detection technique, liquid biopsy is convenient to obtain samples and has broad clinical application in early diagnosis of cervical lymph node metastasis of thyroid cancer. In addition, the analysis and application of liquid biopsy biomarkers will help the development of clinical diagnosis and treatment strategies, and provide the possibility of early precision therapy for thyroid cancer patients. This review summarizes current research surrounding the molecular markers related to cervical lymph node metastasis of thyroid cancer.
RESUMEN
With the progress of comprehensive treatment of breast cancer, the surgical treatment of axillary lymph nodes presents a degraded treatment mode under the guidance of evidence-based medicine. The indications and contraindications of sentinel lymph node biopsy for early breast cancer have been very clear, but there are still many specific problems in clinical practice that surgeons are concerned about. This article discusses the recently published research on sentinel lymph node biopsy in order to draw the attention of surgical colleagues to the new hot issues of sentinel lymph node biopsy in early breast cancer, and promote standardized surgery and the promotion of new treatment concepts.
