RESUMO
INTRODUCTION: There are no defined criteria for deciding to remove a non-functioning indwelling pleural catheter (IPC) when lung re-expansion on chest X-ray is incomplete. Chest computed tomography (chest CT) is usually used. The objective of this work is to validate the usefulness of chest ultrasound performed by a pulmonologist and by a radiologist compared to chest CT. PATIENTS AND METHODS: Prospective, descriptive, multidisciplinary and multicenter study including patients with malignant pleural effusion and non-functioning IPC without lung reexpansion. Decisions made on the basis of chest ultrasound performed by a pulmonologist, and performed by a radiologist, were compared with chest CT as the gold standard. RESULTS: 18 patients were analyzed, all of them underwent ultrasound by a pulmonologist and chest CT and in 11 of them also ultrasound by a radiologist. The ultrasound performed by the pulmonologist presents a sensitivity of 60%, specificity of 100%, PPV 100% and NPV 66% in the decision of the correct removal of the IPC. The concordance of both ultrasounds (pulmonologist and radiologist) was 100%, with a kappa index of 1. The 4 discordant cases were those in which the IPC was not located on the ultrasound. CONCLUSIONS: Thoracic ultrasound performed by an expert pulmonologist is a valid and simple tool to determine spontaneous pleurodesis and remove a non-functioning IPC, which would make it possible to avoid chest CT in those cases in which lung reexpansion is observed with ultrasonography.

BACKGROUND AND OBJECTIVES: Mesothelioma is an infrequent neoplasm with a poor prognosis that is related to exposure to asbestos and whose peak incidence in Europe is estimated from 2020. Its diagnosis is complex; imaging techniques and the performance of invasive pleural techniques being essential for pathological confirmation. The different diagnostic yields of these invasive techniques are collected in the medical literature. The present work consisted of reviewing how the definitive diagnosis of mesothelioma cases in our centre was reached to check if there was concordance with the data in the bibliography. MATERIALS AND METHODS: Retrospective review of patients with a diagnosis of pleural mesothelioma in the period 2019-2021, analysing demographic data and exposure to asbestos, the semiology of the radiological findings and the invasive techniques performed to reach the diagnosis. RESULTS: Twenty-six mesothelioma cases were reviewed. 22 men and 4 women. Median age 74 years. 9 patients had a history of asbestos exposure. Moderate-severe pleural effusion was the most frequent radiological finding (23/26). The sensitivity of the invasive techniques was as follows: Cytology 13%, biopsy without image guidance 11%, image-guided biopsy 93%, surgical biopsy 67%. CONCLUSIONS: In our review, pleural biopsy performed with image guidance was the test that had the highest diagnostic yield, so it should be considered as the initial invasive test for the study of mesothelioma.

Objetivo En nuestro estudio el objetivo fue investigar la contribución de los hallazgos de la tomografía por emisión de positrones (PET)/tomografía computarizada (TC) en la diferenciación no invasiva entre el derrame pleural (DP) de origen benigno (DPB) y maligno (DPM) en pacientes diagnosticadas de un carcinoma de ovario (CO). Material y método Se incluyeron en el estudio a 32 pacientes diagnosticadas de CO con DP. Se efectuó análisis comparativo entre el DPB y el DPM para los siguientes parámetros: SUVmáx. del DP, índice objeto/fondo (TBRp: target/background ratio) del DP, dividiendo el SUVmáx. del DP por el SUVmedio del flujo sanguíneo mediastínico (MBP: medistinal blood pool), engrosamiento pleural, adenopatías supradiafragmáticas, DP unilateral o bilateral, diámetro del DP, edad de la paciente y niveles de CA125. Resultados La edad media de las 32 pacientes fue de 57±2,8 años. Se observó mayor frecuencia significativa de un TBRp>1,1, engrosamiento pleural y ganglios linfáticos supradiafragmáticos en el DPM respecto al DPB. Aunque no se detectó ningún nódulo pleural en las pacientes con DPB, estos estuvieron presentes en 7 pacientes con DPM. En la distinción DMP-DBP la sensibilidad del TBRp fue del 95,2% y la especificidad del 72,7%, la sensibilidad del engrosamiento pleural fue del 80,9%, y la especificidad del 81,8%, la sensibilidad de los ganglios linfáticos supradiafragmáticos fue del 38% y la especificidad del 90,9%, y la sensibilidad del nódulo pleural fue del 33,3% y la especificidad del 100%. No hubo diferencias significativas entre los 2 grupos respecto al resto de factores. Conclusión El engrosamiento pleural y el valor de TBRp determinados en la PET/TC pueden contribuir a la diferenciación entre DMP y DBP, especialmente en aquellas pacientes con CO en estadio avanzado y mal estado general, o que no son tributarias de ser sometidas a tratamiento quirúrgico (AU)
Objective The present study investigates the ability of non-invasive contribution of positron emission tomography (PET)/computed tomography (CT) to distinguish between benign pleural effusions (BPE) and malignant pleural effusions (MPE) in patients diagnosed with ovarian carcinoma (OC). Material and method Included in the study were 32 OC patients with a PE diagnosis. The cases with BPE and MPE were compared in terms of the PE maximum standardized uptake value (SUVmax), PE SUVmax/mean standardized uptake (SUVmean) value of the mediastinal blood pool (TBRp), the presence of pleural thickening, the presence of supradiaphragmatic lymph node, unilateral or bilateral PE, pleural effusion diameter, patient age and CA125 value. Results The mean age of the 32 patients was 57±2.8 years. TBRp>1.1, pleural thickening and supradiaphragmatic lymph node were observed significantly more frequently in the MPE than the BPE cases. While no pleural nodules were detected in patients with BPE, they were present in 7 of the patients with MPE. The rates of distinction between the MPE and BPE cases were as follows: the sensitivity of the TBRp value was 95.2% and specificity was 72.7%; the sensitivity of pleural thickness was 80.9% and specificity was 81.8%; the sensitivity of supradiaphragmatic lymph node was 38% and specificity was 90.9%; and the sensitivity of the pleural nodule was 33.3% and specificity was 100%. There were no significant differences between two groups in any other factors. Conclusion Pleural thickening and TBRp values ascertained through PET/CT may aid the distinction between MPE-BPE, especially in patients with advanced stage OC with a poor general condition, or those who cannot undergo surgery (AU)

Presentamos un caso clínico de una paciente de 34 años con diagnóstico simultáneo de sarcoidosis y tuberculosis, sin ser inmunodeprimida ni tener factores de riesgo para ello. Esto supone un hallazgo muy poco común, y cuando aparece suele deberse a la inmunosupresión ocasionada por el tratamiento con esteroides de la sarcoidosis. En el caso que vamos a describir a continuación este hecho no sucede, motivo por el que se le otorga relevancia. Para llegar a los dos diagnósticos se realizaron las pruebas complementarias necesarias (analíticas sanguíneas, biopsias transbronquiales, pruebas de imagen, toracocentesis y biopsias pleurales), lo que permitió instaurar el tratamiento adecuado y, en consecuencia, la mejoría de la paciente. Con la presentación de este caso se pretende recalcar la importancia de hacer un buen enfoque diagnóstico en el servicio de urgencias, haciendo un hincapié en todos los signos y síntomas tanto directos como indirectos. (AU)
We report a case study of a 34-year-old patient with a simultaneous diagnosis of sarcoidosis and tuberculosis. The patient was not immunosuppressed and did not have risk factors for this. This is a very rare finding, and when it appears it is usually due to immunosuppression caused by corticosteroid treatment of sarcoidosis. In the case reported below, this does not occur, which is why it is relevant. To make both diagnoses, the necessary complementary tests were performed (blood tests, transbronchial biopsies, imaging tests, thoracentesis and pleural biopsies), which enabled appropriate treatment to be established and, consequently, the patient's improvement. Reporting this case enables us to emphasize the importance of making a good diagnosis in A&E, emphasizing all direct and indirect signs and symptoms. (AU)

Introducción: El biliotórax es una condición infrecuente definida por la presencia de bilis en el espacio pleural. Actualmente, hay alrededor de 70 casos descritos en la litera-tura. Sigue siendo relativamente desconocido, por lo tanto, poco sospechado. Esta entidad suele ser el resultado de una lesión iatrogénica, a menudo secundaria a cirugías o traumatismos del tracto biliar, que conduce a la formación de una fístula pleurobiliar.
Introduction: Bilothorax is a rare condition defined by the presence of bile in the pleural space. Currently, there are around 70 cases described in the literature. It remains relatively unknown and, therefore, little suspected. This entity is usually the result of an iatrogenic injury, often secondary to surgery or trauma to the biliary tract, leading to the formation of a pleurobiliary fistula

Background and objectives The results of previous PET-CT studies are contradictory for discriminating malignant from benign pleural effusions. We purpose to develop a PET-CT score for differentiating between benign and malignant effusions. Patients and methods We conducted a prospective study of consecutive patients with pleural effusions undergoing PET-CT from October 2013 to October 2019 (referral cohort). PET-CT scan features evaluated using the SUV were: linear thickening; nodular thickening; nodules; masses; circumferential thickening; mediastinal and fissural pleural involvement; intrathoracic lymph nodes; pleural loculation; inflammatory consolidation; pleural calcification; cardiomegaly; pericardial effusion; bilateral effusion; lung mass; liver metastasis and other extra-pleural malignancy. The results were validated in an independent prospective cohort from November 2019 to June 2021. Results One hundred and ninety-nine patients were enrolled in the referral cohort (91 with malignant effusions and 108 benign). The most useful parameters for the development of a PET-CT score were: nodular pleural thickening, pleural nodules with SUV>7.5, lung mass or extra pleural malignancy (10 points each), mammary lymph node with SUV>4.5 (5 points) and cardiomegaly (−1 point). With a cut-off value of >9 points in the referral cohort, the score established the diagnosis of malignant pleural effusion with sensitivity 87.9%, specificity 90.7%, positive predictive value 88.9%, negative predictive value 89.9%, positive likelihood ratio 7.81 and negative likelihood ratio 0.106. These results were validated in an independent prospective cohort of 75 patients. Conclusions PET-CT score was shown to provide relevant information for the identification of malignant pleural effusion (AU)
Antecedentes y objetivos Los estudios PET-TAC previos en el análisis del derrame pleural son contradictorios. Nuestro objetivo es desarrollar una puntuación mediante PET-TAC para diferenciar entre derrames benignos y malignos. Pacientes y métodos Estudio prospectivo en pacientes con derrame pleural a los que se realizó una PET-TAC desde octubre de 2013 hasta octubre de 2019 (cohorte de referencia). Los datos analizados fueron: engrosamiento lineal; engrosamiento nodular; nódulos; masas; engrosamiento circunferencial; afectación pleural mediastínica y cisural; ganglios linfáticos torácicos; loculación pleural; consolidación; calcificación pleural; cardiomegalia; derrame pericárdico; derrame bilateral; masa pulmonar; metástasis hepáticas y otras neoplasias malignas extrapleurales. Se calculó el SUV de todos estos parámetros. Los resultados se validaron en una cohorte independiente. Resultados Se incluyó a 199 pacientes en la cohorte de referencia (91 derrames malignos y 108 benignos). Los parámetros que mostraron más utilidad para discriminar ambos derrames y desarrollar una puntuación fueron: engrosamiento pleural nodular, nódulos pleurales con SUV > 7,5, masa pulmonar o malignidad extrapleural (10 puntos cada uno), ganglio en cadena mamaria con SUV > 4,5 (5 puntos) y cardiomegalia (1 punto). Con un punto de corte > 9 en la cohorte de derivación, se estableció el diagnóstico de derrame pleural maligno con una sensibilidad del 87,9%, especificidad del 90,7%, valor predictivo positivo del 88,9%, valor predictivo negativo del 89,9% razón de verosimilitud positiva del 7,81 y razón de verosimilitud negativa del 0,106. Estos resultados fueron validados en una cohorte prospectiva independiente de 75 pacientes. Conclusiones Una puntuación basada en PET-TAC proporciona información relevante para el diagnóstico del derrame pleural maligno (AU)

El síndrome de las uñas amarillas es una enfermedad rara de etiología desconocida, caracterizado por una coloración amarillenta de las uñas, manifestaciones respiratorias y linfedemas primarios1. Existe poca literatura científica en referencia a estudios autópsicos de pacientes con este síndrome, así como respecto a su etiología, si bien se postula que es causada por una malformación de los conductos linfáticos. En este artículo presentamos el caso de una paciente diagnosticada en vida de síndrome de las uñas amarillas en cuyo estudio autópsico se encontraron algunos hallazgos previamente no descritos, como dilatación de los senos de ganglios linfáticos mediastinales y esplénicos.(AU)
Yellow nail syndrome is a rare disease of unknown aetiology. Patients with YNS have a characteristic yellowish-coloured nails, pulmonary alterations and primary lymphedema. To the best of our knowledge, only a few reports of autopsy findings in these patients have been published. Its aetiology possibly involves a primary malformation of larger lymph vessels. We describe autopsy findings not previously associated with yellow nail syndrome, such as expansion of mediastinal lymph-nodes and splenic sinusoids.The present autopsy reveals hitherto unreported findings associated with YNS, such as alterations in splenic sinusoids and mediastinal lymph-node sinuses.(AU)

Introducción: La incidencia del derrame pleural paraneumónico, incluyendo el empiema, ha sufrido variaciones en las últimas décadas, que se han relacionado con la implantación de distintos tipos de vacuna antineumocócica conjugada. Métodos: Se han revisado retrospectivamente los datos de los 10 hospitales públicos de la provincia de Alicante (España), que abarcan una población de 279.000 niños menores de 15 años, entre 2010 y 2018. Se desglosaron los derrames menores de 10mm (DP−) y los de 10mm o más (DP+). Resultados: Se han analizado 366 episodios de derrame pleural paraneumónico, 178 DP− (48,6%) y 188 DP+ (51,4%), con una mediana de edad de 4 años (rango intercuartílico: 2-7 años) y una evidente estacionalidad con máximo en invierno y mínimo en verano. Se identificó al agente etiológico por cultivo en 34 pacientes (9,3%), destacando Streptococcus pneumoniae (24 pacientes) seguido por Streptococcus pyogenes (7 pacientes). El serotipo de S. pneumoniae más frecuente fue el 19A (6 pacientes) y se han identificado 3 fallos vacunales. La tasa anual media de incidencia fue de 14,3 casos por 100.000 menores de 15 años (7,0 para DP− y 7,3 para DP+), sin cambios significativos a lo largo del tiempo, aunque sí se apreciaron diferencias marcadas de la incidencia entre los distintos departamentos sanitarios. Conclusiones: No hemos encontrado variaciones temporales en la incidencia del derrame paraneumónico pese a la implementación de la vacuna antineumocócica conjugada de 13 serotipos. Es destacable la variabilidad de la incidencia entre departamentos vecinos sin motivo aparente.(AU)
Introduction: The reported incidence of parapneumonic pleural effusion, including empyema, has shown fluctuations in the last decades. It has been related to the implementation of different types of conjugate pneumococcal vaccines. Methods: We have retrospectively reviewed data from all 10 public hospitals in Alicante Province (Spain) covering a population of 279,000 children under 15 years of age, between 2010 and 2018. Effusions less than 10mm (PE−) and those of 10mm or more (PE+) were separated. Results: A total of 366 episodes of parapneumonic pleural effusion have been analyzed, 178 PE− (48.6%) and 188 PE+ (51.4%), with a median age of 4 years (interquartile range: 2-7 years) and marked seasonality with the maximum in winter and the minimum in summer. A culture proven bacterial agent was identified in 34 patients (9.3%), mainly Streptococcus pneumoniae (24 patients) followed by Streptococcus pyogenes (7 patients). The most frequent S. pneumoniae serotype was 19A (6 patients) and 3 vaccine failures were observed. The mean annual incidence rate was 14.3 cases per 100,000 children under 15 years of age (7.0 for PE− and 7.3 for PE+). No significant changes were observed in incidence over time, but noticeable differences in incidence were observed in different health departments. Conclusions: We have not found temporal variations in incidence of parapneumonic effusion despite the implementation of the 13-valent pneumococcal conjugate vaccine. The unexplained disparity in incidence between close departments is noteworthy.(AU)

O objetivo deste estudo é descrever o caso de mulher com síndrome de Meigs e apresentar a revisão narrativa sobre o tema. Paciente do sexo feminino, 30 anos, nulípara, encaminhada ao hospital por massa anexial e história prévia de drenagem de derrame pleural. Evoluiu com instabilidade hemodinâmica por derrame pleural hipertensivo à direita, sendo submetida a drenagem torácica, com citologia do líquido negativa. Após, foi submetida a laparotomia: realizada salpingo-ooforectomia esquerda. A congelação e a análise histopatológica diagnosticaram fibroma ovariano. A citologia ascítica foi negativa. CA-125 elevado, presença de derrames cavitários e exame de imagem suspeito podem mimetizar um cenário de neoplasia maligna de ovário em estágio avançado. Entretanto, na síndrome de Meigs clássica, o tratamento é cirúrgico, sendo o diagnóstico obtido por meio da análise histopatológica do tumor ovariano. O manejo da síndrome de Meigs clássica é cirúrgico e, após a remoção do tumor, o derrame pleural e a ascite desaparecem.
To describe a case of Meigs syndrome and present a narrative review of the condition. Female patient, 30 years old, nulliparous, referred to the hospital due to an adnexal mass and a previous drainage of pleural effusion. She developed hemodynamic instability due to a hypertensive right pleural effusion being submitted to chest drainage, with negative cytology of the fluid. She underwent laparotomy: Left salpingo-oophorectomy was performed and frozen section and histopathological analysis diagnosed an ovarian fibroma. Ascites cytology was negative. Elevated CA-125, presence of cavitary effusions, suspicious imaging exam can mimic a scenario of ovarian cancer at an advanced stage. However, in classical Meigs syndrome, treatment is surgical, and the diagnosis is obtained through histopathological analysis of the ovarian tumor. Classical Meigs syndrome' management is surgical. After tumor removal, pleural effusion and ascites resolve.

Introducción No se ha determinado la evolución de los pacientes con derrames pleurales idiopáticos con un seguimiento a largo plazo. Métodos Entre octubre de 2013 y junio de 2021 se hizo un seguimiento prospectivo de todos los pacientes con derrame idiopático mediante exploración clínica y estudios de imagen al cabo de 1, 3 y seis meses y cada seis meses durante un mínimo de un año. Resultados Veintinueve pacientes fueron diagnosticados de derrame idiopático y objeto de seguimiento. Durante el seguimiento se detectó un mesotelioma en dos pacientes al cabo de siete y 18 meses; en uno de ellos se observó líquido pleural teñido de sangre y el otro refirió una pérdida de peso de 10%. En ninguno de los pacientes con derrame que cubriera menos de dos tercios del hemitórax y sin síntomas constitucionales ni aparición de líquido teñido de sangre se diagnosticó un mesotelioma. La mayoría de los derrames desaparecieron o mostraron una clara mejoría en los primeros seis meses. Conclusiones Los pacientes sin pérdida de peso y con derrames no hemáticos pequeños pueden beneficiarse de un tratamiento conservador y un seguimiento clínico-radiológico (AU)
Introduction Long-term follow-up course for patients with idiopathic pleural effusions has not been established. Methods From October 2013 to June 2021 all patients with idiopathic effusion were prospectively followed up with clinical examination and imaging at 1,3,6 and every 6 months for a minimum of 1 year. Results Twenty-nine patients were diagnosed with idiopathic effusion and followed up. Mesothelioma was detected during the follow-up in two patients at 7 and 18 months, one of whom had blood-tinged pleural fluid and the other reported a 10% weight loss. Mesothelioma was not diagnosed in any of the patients with effusion covering less than two thirds of the hemithorax, and without constitutional symptoms or a blood-tinged fluid appearance. Most of the effusions resolved or showed a clear improvement in the first six months. Conclusions Patients without weight loss and with small, non-hematic effusions, may benefit from conservative treatment and clinical-radiological follow-up (AU)

OBJECTIVE: The present study investigates the ability of non-invasive contribution of positron emission tomography (PET)/computed tomography (CT) to distinguish between benign pleural effusions (BPE) and malignant pleural effusions (MPE) in patients diagnosed with ovarian carcinoma (OC). MATERIAL AND METHODS: Included in the study were 32 OC patients with a PE diagnosis. The cases with BPE and MPE were compared in terms of the PE maximum standardized uptake value (SUVmax), PE SUVmax/mean standardized uptake (SUVmean) value of the mediastinal blood pool (TBRp), the presence of pleural thickening, the presence of supradiaphragmatic lymph node, unilateral or bilateral PE, pleural effusion diameter, patient age and CA125 value. RESULTS: The mean age of the 32 patients was 57±2.8 years. TBRp>1.1, pleural thickening and supradiaphragmatic lymph node were observed significantly more frequently in the MPE than the BPE cases. While no pleural nodules were detected in patients with BPE, they were present in 7 of the patients with MPE. The rates of distinction between the MPE and BPE cases were as follows: the sensitivity of the TBRp value was 95.2% and specificity was 72.7%; the sensitivity of pleural thickness was 80.9% and specificity was 81.8%; the sensitivity of supradiaphragmatic lymph node was 38% and specificity was 90.9%; and the sensitivity of the pleural nodule was 33.3% and specificity was 100%. There were no significant differences between two groups in any other factors. CONCLUSIONS: Pleural thickening and TBRp values ascertained through PET/CT may aid the distinction between MPE-BPE, especially in patients with advanced stage OC with a poor general condition, or those who cannot undergo surgery.

It has been related to the implementation of different types of conjugate pneumococcal vaccines. METHODS: We have retrospectively reviewed data from all 10 public hospitals in Alicante Province (Spain) covering a population of 279,000 children under 15 years of age, between 2010 and 2018. Effusions less than 10 mm (PE-) and those of 10â¯mm or more (PE+) were separated. RESULTS: A total of 366 episodes of parapneumonic pleural effusion have been analyzed, 178 PE- (48.6%) and 188 PE+ (51.4%), with a median age of 4 years (interquartile range: 2-7 years) and marked seasonality with the maximum in winter and the minimum in summer. A culture proven bacterial agent was identified in 34 patients (9.3%), mainly Streptococcus pneumoniae (24 patients) followed by Streptococcus pyogenes (7 patients). The most frequent S. pneumoniae serotype was 19A (6 patients) and 3 vaccine failures were observed. The mean annual incidence rate was 14.3 cases per 100,000 children under 15 years of age (7.0 for PE- and 7.3 for PE+). No significant changes were observed in incidence over time, but noticeable differences in incidence were observed in different health departments. CONCLUSIONS: We have not found temporal variations in incidence of parapneumonic effusion despite the implementation of the 13-valent pneumococcal conjugate vaccine. The unexplained disparity in incidence between close departments is noteworthy.
RESUMO
Introducción: El quilotórax congénito es una rara afección respiratoria, sin embargo, es la causa más frecuente de derrame pleural en recién nacidos vivos. Objetivo: Presentar un caso de quilotórax congénito como causa infrecuente de distrés respiratorio en un recién nacido atendido en el Hospital Gineco-Obstétrico de Villa Clara. Caso clínico: Paciente masculino, que nació a las 26,2 semanas de edad gestacional, por parto eutócico, con tiempo de rotura de membranas de una hora, líquido amniótico meconial, otorgándose una puntuación de Apgar 7/8 (normal) y peso al nacer de 950 gramos; con diagnóstico de sepsis connatal fue necesario tratar con ventilación mecánica. A los seis días de vida presentó un deterioro clínico, con disminución del murmullo vesicular en el hemitórax derecho y en la radiografía de tórax se observó un pulmón derecho velado. El ultrasonido torácico confirmó el diagnóstico de derrame pleural derecho que fue puncionado y el estudio del líquido drenado mostró características propias del quilotórax. Se le indicó tratamiento conservador (con alimentación parenteral completa: traximín sin aporte lipídico) y luego con leche rica en ácidos grasos de cadenas corta y media (Enfaport® de la firma Nestlé). Se incorporó la leche materna a los 15 días del diagnóstico. Requirió ventilación mecánica prolongada. Con una evolución satisfactoria es egresado del centro hospitalario. Conclusiones: Se logró la resolución de esta enfermedad a través del tratamiento conservador, sin la presencia de recidiva.
Introduction: Congenital chylothorax is a rare respiratory disease; however, it is the most common cause of pleural effusion in live newborns. Objective: To present a case of congenital chylothorax as an uncommon cause of respiratory distress in a newborn treated at the Gyneco-Obstetric Hospital of Villa Clara. Case report: Male patient, who was born at 26.2 weeks of gestational age, by eutocic delivery, with membrane time rupture of an hour, meconium amniotic fluid, to whom was given an Apgar score of 7/8 (normal) and a birth weight of 950 grams; with diagnose of connatal sepsis was necessary to treat with mechanical ventilation. At six days of age presented a clinical deterioration, with decrease of the vesicular murmur in the right hemithorax and at chest X-ray was observed a veiled right lung. The chest ultrasound confirmed a right pleural effusion that was punctured and the study of the drained fluid showed characteristics of a chylothorax. Conservative treatment was indicated (with complete parenteral feeding: traximin without lipid intake) and subsequently with milk rich in short and medium chain fatty acids (Enfaport® from Nestlé Company). Breastmilk was incorporated 15 days after the diagnose. He required prolonged mechanical ventilation. With a satisfactory evolution, he was discharged from the hospital center. Conclusions: The resolution of this entity is achieved through conservative treatment, without the presence of recurrence.
RESUMO
Resumen ANTECEDENTES: El cáncer de mama es la segunda neoplasia maligna más común asociada con el embarazo. Su tratamiento es complejo debido a los riesgos en el feto en el contexto del tratamiento de la madre. CASO CLÍNICO: Paciente de 28 años, enviada del Hospital Naval de Chetumal, Quintana Roo, con 13.1 semanas de embarazo por fecha de la última menstruación. En la tomografía computada se advirtió la existencia de un derrame pleural del 70%, otro pericárdico y sospecha de metástasis osteoblástica a la columna torácica. En la exploración física se encontró con dinámica ventilatoria, amplexión y amplexación disminuida derecha, hipoventilación interescapular y basal derecha, con disminución a la trasmisión de voz, submatidez basal derecha y, hacia el lado izquierdo, un murmullo vesicular. Los estudios citoquímico y citológico de líquido pericárdico y pleural se reportaron positivos para malignidad. En la resonancia magnética de la columna se encontraron lesiones sugerentes de actividad tumoral en los cuerpos vertebrales T12 a L5. Debido al avanzado estado metastásico del cáncer se propuso la interrupción del embarazo con el propósito de no retrasar el tratamiento. El perfil biológico reportó: inmunofenotipo triple negativo (receptores de estrógeno y progesterona: negativo, HER2: negativo en células neoplásicas). Se le indicó tratamiento con quimioterapia sistémica (carboplatino-paclitaxel). CONCLUSIÓN: El diagnóstico de cáncer de mama durante el embarazo dificulta la detección e interpretación de las anormalidades mamarias, retrasa el diagnóstico, permite el crecimiento del tumor y se incrementa el riesgo metastásico de la enfermedad. El tratamiento oncológico adecuado y su valoración multidisciplinaria son decisivos para favorecer la supervivencia.
Abstract BACKGROUND: Breast cancer is the second most common malignancy associated with pregnancy. Its treatment is complex due to fetal risks in the context of treatment of the mother. CLINICAL CASE: 28-year-old patient, referred from the Naval Hospital of Chetumal, Quintana Roo, with 13.1 weeks of pregnancy by date of last menstrual period. The CT scan showed a 70% pleural effusion, another pericardial effusion and suspicion of osteoblastic metastasis to the thoracic spine. Physical examination showed ventilatory dynamics, decreased right amplexion and amplexation, interscapular and right basal hypoventilation, with decreased voice transmission, right basal submatitis and, to the left side, a vesicular murmur. Cytochemical and cytological studies of pericardial and pleural fluid were positive for malignancy. MRI of the spine showed lesions suggestive of tumor activity in the vertebral bodies T12 to L5. Due to the advanced metastatic stage of the cancer, termination of pregnancy was proposed in order not to delay treatment. The biological profile reported: triple negative immunophenotype (estrogen and progesterone receptors: negative, HER2: negative in neoplastic cells). Treatment with systemic chemotherapy (carboplatin-paclitaxel) was indicated. CONCLUSION: The diagnosis of breast cancer during pregnancy hinders the detection and interpretation of breast abnormalities, delays diagnosis, allows tumor growth and increases the metastatic risk of the disease. Adequate oncologic treatment and its multidisciplinary assessment are decisive in favoring survival.
RESUMO
Introducción: El derrame pleural paraneumónico resulta la complicación más frecuente de la neumonía bacteriana, de manejo complejo y muchas veces quirúrgico. No existen publicaciones en Cuba provenientes de ensayos clínicos controlados y aleatorizados ni del uso de la estreptoquinasa recombinante (Heberkinasa®) en el derrame pleural. Objetivo: Evaluar la eficacia y la seguridad de la Heberkinasa® en el tratamiento del derrame pleural paraneumónico complicado complejo y el empiema en niños. Métodos: Ensayo clínico fase III, abierto, aleatorizado (2:1), en grupos paralelos y controlado. Se concluyó la inclusión prevista de 48 niños (1-18 años de edad), que cumplieron los criterios de selección. Los progenitores otorgaron el consentimiento informado. Los pacientes se distribuyeron en dos grupos: I- experimental: terapia estándar y administración intrapleural diaria de 200 000 UI de Heberkinasa® durante 3-5 días y II-control: tratamiento estándar. Las variables principales: necesidad de cirugía y la estadía hospitalaria. Se evaluaron los eventos adversos. Resultados: Ningún paciente del grupo I-experimental requirió cirugía, a diferencia del grupo II-control en el que 37,5 por ciento necesitó cirugía video-toracoscópica, con diferencia altamente significativa. Se redujo la estadía hospitalaria (en cuatro días), las complicaciones intratorácicas y las infecciones asociadas a la asistencia sanitaria en el grupo que recibió Heberkinasa®. No se presentaron eventos adversos graves atribuibles al producto. Conclusiones: La Heberkinasa® en el derrame pleural paraneumónico complicado complejo y empiema resultó eficaz y segura para la evacuación del foco séptico, con reducción de la necesidad de tratamiento quirúrgico, de la estadía hospitalaria y de las complicaciones, sin eventos adversos relacionados con su administración(AU)
Introduction: Paraneumonic pleural effusion is the most frequent complication of bacterial pneumonia, with complex and often surgical management. There are no publications in Cuba from randomized controlled clinical trials or the use of recombinant streptokinase (Heberkinase®) in pleural effusion. Objective: To evaluate the efficacy and safety of Heberkinase® in the treatment of complex complicated parapneumonic pleural effusion and empyema in children. Methods: Phase III, open-label, randomized (2:1), parallel-group, controlled clinical trial. The planned inclusion of 48 children (1-18 years of age), who met the selection criteria, was completed. Parents gave informed consent. The patients were divided into two groups: I-experimental: standard therapy and daily intrapleural administration of 200,000 IU of Heberkinase® for 3-5 days; and II-control: standard treatment. The main variables: need for surgery and hospital stay. Adverse events were evaluated. Results: No patient in group I-experimental required surgery, unlike group II-control in which 37.5 percent required video-assisted thoracoscopic surgery, with a highly significant difference. Hospital stay (to 4 days), intrathoracic complications and infections associated to healthcare in the group that received Heberkinase® was reduced. No serious adverse events attributable to the product occurred. Conclusions: Heberkinase® in complex complicated parapneumonic pleural effusion and empyema was effective and safe for the draining of the septic focus, with reduction of the need for surgical treatment, hospital stay and complications, with no adverse events related to its administration(AU)
