It is a rapidly progressive disease with high mortality rates close to 100 percent if it is not treated in time. Objective: To describe the case of a patient with right pleural empyema secondary to a ruptured pyogenic abscess of the left hepatic lobe. Clinical case: A 70-year-old female patient who came to emergency with fever, abdominal pain and general syndrome. The computed tomography scan showed a liver abscess in the left lobe with almost total liquefaction, and later a right thoracic empyema was a complication. The patient was treated with chest tube drainage. Despite timely antibiotic and surgical treatments, the patient died of septic shock. Conclusions: A rare case of empyema secondary to liver abscess of the left lobe is reported. The delay of the patient in going to health institutions led to the death of the patient despite antibiotic and surgical treatment(AU)

Abscesos hepaticos en tiempos de pandemia (covid19) / Hepatic abscesses in time of pandemic (COVID 19)

Introducción. Los abscesos hepáticos son infecciones focales supurativas. La Klebsiella pneumoniae es el agente etiológico más frecuente. Afecta principalmente a hombres de edad media, diabéticos, con afecciones hepáticas o en contexto de inmunodepresión. Se clasifican en abscesos colangíticos, pioflebíticos, hematógenos, por continuidad, traumáticos y criptogénicos, según mecanismo de producción. Se manifiestan con dolor abdominal en hipocondrio derecho, sd. febril y sd. colestásico en presencia de obstrucción de vía biliar. La ecografía, TAC y la Resonancia magnética de abdomen son los métodos de elección para determinar topografía y morfología de las colecciones. El tratamiento consiste en el drenaje oportuno de la colección por vía percutánea o quirúrgica, asociado al tratamiento antibiótico. Objetivos: 1. Análisis epidemiológico de abscesos hepáticos durante la Pandemia por Covid 19 en una Institución privada de Tucumán. 2. Estudiar la fisiopatología y agentes patógenos responsables de los mismos. 3. Comparar estadísticas con era similar no Covid 19. Material y métodos. Estudio descriptivo retrospectivo. Se incluyeron seis pacientes con diagnóstico de Absceso Hepático, cinco de ellos del período de la era Covid 19 y uno de la era no Covid 19. Las variables analizadas fueron: cantidad de pacientes ingresados al Servicio, pacientes con absceso hepático, sexo, edad, comorbilidades, métodos de diagnóstico imagenológico utilizados, localización anatómica del absceso, número de lesiones, microbiología de la muestra quirúrgica y en sangre, tratamiento implementado, días desde el diagnóstico hasta la resolución, STROC y recidiva. Resultados: En el análisis epidemiológico se evidenció un notable descenso de la actividad quirúrgica en el periodo del 2020, respecto al mismo período del año previo, a predominio del mes de abril con un porcentaje de descenso del 52%, coincidiendo este período con el inicio de la cuarentena en la provincia. En nuestra serie resultaron todos masculinos, hipertensos y 3 de ellos diabéticos. Todos estudiados por ecografía y 3 complementaron con TAC con contraste EV. Fueron tratados en un promedio de 48hs desde el diagnóstico. Cultivos positivos, Klebsiella Pn (3), St aureus (1), E. Coli (1), Bacilo gram ­ (1). Hemocultivos: 3 negativos, 2 positivos para Klebsiella Pn y 1 para St. Aureus. 3 pacientes fueron sometidos a drenaje percutáneo, 2 a laparoscópico y uno convencional. Se registraron 2 STROC IIIA y 1 IIIB. Un paciente obitó, el resto recibió alta sanatorial. Se registraron 2 recidivas. Conclusiones: Nuestros pacientes, en su totalidad masculinos y diabéticos, desarrollaron abscesos hepáticos piógenos; el agente patógeno más frecuente fue la Klebsiella Pneumoniae. Los abscesos criptogénicos fueron los más prevalentes. En las recidivas documentadas, se determinó misma ubicación topográfica y agente etiológico del primer episodio, lo que nos lleva a preguntarnos sobre la eficacia del tratamiento implementado en cada caso.

Introduction: liver abscess is a common infection. Klebsiella pneumoniae was de most frecuently etiologic agent. The patients were middle-aged men with diabetes, another liver afection or immunodepression context. According to the production mechanism, they are classified in colangitics, pyophlebics, haematogenes, by continuity, traumatic and cryptogrnics. Patients usually present with right upper quadrant, fever, colestasic síndrome when bile-way obstruction exist. Imaging techniques such as ultrasonography, computed tomography scanning and magnetic resonance are useful tools to demostrtate a space occupying lesión and morfology of liver abscess. Treatment consist in timely drainage by percutaneous or surgical route, plus antibiotic treatment. Objetives: 1. Epidemiological análisis of liver abscesses during the pandemic Covid 19 in a private center in Tucumán. 2. Study physiology and pathogenic agents. 3. Campare statistics whit previusly period. Materials and methods: retrospective descriptive study. Six live abscess diagnosis patient were included, five of them included in stage Covid 19 and only one belong stage no Covid 19. Variables analysed: number of patients belong to the Service, number of patients whit liver abscess diagnosis, sex, age, comorbilities, imaging methods, location and number of abscess, microbiology of surgical sample and blood, treatment, days from diagnosis to resolution, STROC and recidivation. Results: epidemiological análisis showed a decrease in surgeries in the period 2020, compared to the same period of the previous year, a predominance in April with a percentage decrease of 52%, coinciding with the start of quarantine in the province. All patients were male, hypertensive and 3 of them with diabetes. Al lof them studied by ultrasound and tomography with contrast. They were treated at 48hours of diagnosis. Microbiology of surgical sample positive: Klebsiella Pn (3), St aureus (1), E. Coli (1), Bacillos gram ­ (1). Microbiology of blood: 3 negative, 2 positive to Klebsiella Pn and 1 to St. Aureus. 3 patients were drainage by percutaneous , 2 by laparoscopic and 1 by surgical conventional. They registered 2 STROC IIIA y 1 IIIB. 1 patiente dead, the rest were external from hospital. Conclusions: our patients developed liver abscess, they were male, diabetics and the most frecuently agent was the Klebsiella pneumoniae. Criptogenics abscess were the most prevalent. The same topographic location in the liver and the etiologic agent was determined in recurrence. That´s why we wonder about the effectiveness of the treatment implemented.

Type 1 autoimmune pancreatitis: relapse with liver abscess / Pancreatite autoimune tipo 1: recidiva com abscesso hepático

ABSTRACT: Type 1 autoimmune pancreatitis is a cause of chronic pancreatitis related to the systemic disease known as IgG4-related Sclerosing Disease. Case report: We report the case of a 64-year-old male patient who presented recurrentepigastric pain radiating to the back, associated with jaundice, xerostomia, nausea, and vomiting, since 2014, diagnosed two years later with an unresectable pancreatic adenocarcinoma. The diagnosis was questioned after a few follow-up months without clinical deterioration when it was suggested the possibility of type 1 autoimmune pancreatitis in its pseudotumoral form. The patient was then treated with glucocorticoids, obtaining significantclinical improvement. After two years of follow-up, he returned asymptomatic with images suggestive of sclerosingcholangitis and a large liver abscess. Importance of the issue: The present case denotes the difficulty found in this diagnosis due to clinical and radiological resemblances with pancreatic adenocarcinoma. Besides that, it presents a seldom described disease complication, the liver abscess. (AU)

RESUMO: A pancreatite autoimune tipo 1 é uma causa de pancreatite crônica relacionada à doença sistêmica conhecida como Doença Esclerosante relacionada à IgG4. Relato do caso: Relatamos o caso de um paciente do sexo masculino,64 anos, que apresentou quadros recorrentes de dor epigástrica com irradiação para as costas, associada com icterícia, xerostomia, náuseas e vômitos desde 2014, diagnosticado após 2 anos com adenocarcinoma pancreático irressecável. O diagnóstico foi questionado após alguns meses de acompanhamento sem deterioração clínica, quando aventaram a possibilidade de forma pseudotumoral da pancreatite autoimune tipo 1. Realizou tratamento com glicocorticoides, obtendo melhora clínica importante. Após dois anos de acompanhamento, retorna assintomático com imagens sugestivas de colangite esclerosante e volumoso abscesso hepático. Importância do problema: O presente caso denota uma dificuldade encontrada no diagnóstico dessa entidade devido a semelhanças clínico-radiológicas com o adenocarcinoma pancreático. Além disso, apresenta uma complicação pouco descrita da doença, o abscesso hepático. (AU)

Ascariasis hepatobiliar en una lactante con desnutrición severa: reporte de caso / Hepatobiliary ascariasis in severely malnourished infant: case report

Resumen La Ascariasis es la geohelminitiasis más común del mundo, catalogándose como una enfermedad tropical desatendida, que puede causar compromiso pulmonar, gastrointestinal, hepatobiliar y nutricional. Se presenta el caso inusual de una lactante procedente de una zona de extrema pobreza quien consultó por fiebre, vómito, ausencia de deposiciones, distensión y dolor abdominal. Fue diagnosticada con pseudoobstrucción intestinal, desnutrición severa, choque séptico de origen intraabdominal, retraso del neurodesarrollo y deprivación psicoafectiva, cuyas imágenes reportaron ascariasis hepatobiliar y granulomas hepáticos calcificados y abscedados, con infestación severa por Ascaris lumbricoides. Recibió manejo antibiótico y antiparasitario con recuperación exitosa. En nuestro medio, las infecciones por helmintos son causa frecuente de anemia, retraso cognitivo y del crecimiento en niños en edad escolar. Sin embargo, la infestación y complicaciones hepatobiliares como colangitis, colecistitis, pancreatitis, litiasis biliar y hepatitis abscedada son inusuales en menores de dos años. A través de este caso se pretende resaltar la presentación atípica de la enfermedad en lactantes e incitar al fortalecimiento de las intervenciones en salud pública. MÉD.UIS.2020;33(1):67-72.

Abstract Ascariasis is the most common geohelminitiasis in the world. It is categorized as an unattended tropical disease, which can cause pulmonary, gastrointestinal, hepatobiliary and nutritional compromise. We present the unusual case of an infant from an extreme poverty area presenting fever, vomiting, absence of bowel movements, bloating and abdominal pain. She was diagnosed with intestinal pseudoobstruction, severe malnutrition, abdominal septic shock, neurodevelopmental delay and emotional deprivation. The images reported hepatobiliary ascariasis and calcified and abscessed hepatic granulomas, with severe infestation by Ascaris lumbricoides and Trichuris trichiura. She was treated with antibiotics and antiparasitic agents with successful recovery. In our environment, helminth infections are a frequent cause of anemia, stunting and neurodevelopmental delay in school-age children. However, infestation and hepatobiliary complications such as cholangitis, cholecystitis, pancreatitis, biliary lithiasis and hepatic abscess are unusual in children under two years old. Through this case, it is intended to highlight the atypical presentation of this disease at the age of this patient and encourage the strengthening of public health interventions.

Manejo de un aneurisma infeccioso / Treatment of infected aneurysm

Resumen Introducción: Los aneurismas infecciosos constituyen una patología poco frecuente y se caracterizan por presentar infección de la pared del vaso implicado. El mejor tratamiento no está definitivamente establecido. Objetivo: Describir un caso de aneurisma infeccioso con manejo endovascular. Caso clínico: Presentamos un paciente de sexo masculino de 75 años que ingresa por cuadro compatible con abdomen agudo y que en el posoperatorio se pesquisa un aneurisma infeccioso del tronco celíaco, el cual se trata mediante una endoprótesis y manejo antibiótico. Discusión: El manejo tradicional del aneurisma infeccioso es la cirugía abierta que incluye la extirpación o exclusión del aneurisma y de su tejido perivascular infectado, pero conlleva gran morbimortalidad. Conclusión: El aneurisma infeccioso puede ser manejado de forma mínimamente invasiva con técnica endovascular, con baja morbilidad inmediata, pero con resultados a largo plazo aun no concluyentes.

Introduction: Infectious aneurysms are a rare disease and are characterized by infection of the involved vessel wall. The best treatment is definitely not established. Aim: To describe a case of infectious aneurysm with endovascular management. Case report: We present a 75-year-old male patient admitted to a table compatible with acute abdomen and that an infectious aneurysm of the celiac trunk is investigated in the postoperative period, treated with an endoprosthesis and antibiotic management. Discussion: The traditional management of the infectious aneurysm is open surgery that includes the removal or exclusion of the aneurysm and its infected perivascular tissue, but it leads to great morbidity and mortality. Conclusion: The infectious aneurysm can be managed minimally invasively with endovascular technique, with immediate low morbidity, but with long-term results that are still inconclusive.

Septic Pulmonary Embolism Requiring Critical Care: Clinicoradiological Spectrum, Causative Pathogens and Outcomes

OBJECTIVES: Septic pulmonary embolism is an uncommon but life-threatening disorder. However, data on patients with septic pulmonary embolism who require critical care have not been well reported. This study elucidated the clinicoradiological spectrum, causative pathogens and outcomes of septic pulmonary embolism in patients requiring critical care. METHODS: The electronic medical records of 20 patients with septic pulmonary embolism who required intensive care unit admission between January 2005 and December 2013 were reviewed. RESULTS: Multiple organ dysfunction syndrome developed in 85% of the patients, and acute respiratory failure was the most common organ failure (75%). The most common computed tomographic findings included a feeding vessel sign (90%), peripheral nodules without cavities (80%) or with cavities (65%), and peripheral wedge-shaped opacities (75%). The most common primary source of infection was liver abscess (40%), followed by pneumonia (25%). The two most frequent causative pathogens were Klebsiella pneumoniae (50%) and Staphylococcus aureus (35%). Compared with survivors, nonsurvivors had significantly higher serum creatinine, arterial partial pressure of carbon dioxide, and Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores, and they were significantly more likely to have acute kidney injury, disseminated intravascular coagulation and lung abscesses. The in-hospital mortality rate was 30%. Pneumonia was the most common cause of death, followed by liver abscess. CONCLUSIONS: Patients with septic pulmonary embolism who require critical care, especially those with pneumonia and liver abscess, are associated with high mortality. Early diagnosis, appropriate antibiotic therapy, surgical intervention and respiratory support are essential.

Schistosomiasis: predisposing cause for the formation of hepatic abscesses? : case report

Paciente adulto, natural de regiao endemica para esquistossomose e portador cronico da doenca, apresenta queixa de febre ha sete dias, associada a ictericia e dor lombar em regiao direita. Os exames radiologicos mostraram abscessos hepaticos piogenicos multiplos, cuja causa predisponente e conhecida, segundo trabalhos da literatura, em 100 por cento dos casos. Atraves de parametros clinicos, laboratoriais e radiologicos todas as etiologias classicas foram afastadas. Sabe-se que a esquistossomose pode provocar, como complicacao, a pileflebite, alem de depressao imunologica e reacao granulomatosa com necrose lobular central e maior risco de infeccao. Os autores deste relato de caso sugerem ser a esquistossomose, na sua forma cronica, causa predisponente para formacao de abscessos hepaticos piogenicos multiplos, principalmente em regioes endemicas.
