Laparoscopic cholecystectomy in an adult patient with a ventriculoperitoneal shunt system

Adult patients with a ventriculoperitoneal shunt valve (VDVP) are not exempt from suffering from gastrointestinal diseases. Nowadays, with technological advances, it would be contradictory not to offer them the benefits of minimally invasive surgery. The case of a laparoscopic cholecystectomy of a 40-year-old male patient with VDVP who presented clinical signs of cholecystitis is presented. The patient's evolution was satisfactory and he was discharged home 72 hours after surgery. Currently, there are significant studies that demonstrate the benefit of minimally invasive surgery in patients with VDVP as a treatment for abdominal surgical pathologies, including biliary pathology. Therefore, in our experience and with the published cases, we conclude that patients with VDVP do benefit from minimally invasive surgery for any abdominal surgical pathology, including pathology of biliary origin.

Empyema associated with Lemierre syndrome: case report and literature review

Postanginal septicemia, also called Lemierre syndrome, is a metastatic infection that can have multiple complications, including empyema. Therefore, the natural history of the disease begins with an infection of the oropharynx by microbiota from the digestive system, which causes a thrombophlebitis of the jugular vein with septic infiltrations, including into the lungs causing pneumonia, which in turn can generate parapneumonic effusions and/or empyemas. Furthermore, it is a syndrome that was thought to have been forgotten by the era of antibiotics, but with resistance to these antibiotics it has begun to re-emerge. Next, we will talk about a case of a 41-year-old man with no significant pathological history, who entered secondary to a peritonsillar abscess which turned into Lemierre syndrome with a treatment based on broad-spectrum antibiotics and then performed of lung decortication by thoracotomy. Empyema as a complication of Lemierre syndrome is rare and even more so in this post-antibiotic era, so health personnel should have a high clinical suspicion since adequate and timely treatment will help reduce the complications of this disease, as well as like his mortality.

Empiema por Trichomona hominis / Empyema by Trichomona hominis

El empiema pleural es una de las complicaciones de las infecciones del tracto respiratorio inferior y se caracteriza por la presencia de pus en la toracocentesis. Raramente Trichomonas hominis está asociada al empiema como agente causal. En este artículo presentamos el caso de una mujer de 39 años que desarrolló un empiema causado por T. hominis, además de una revisión de la literatura disponible de esta rara infección. Hasta donde sabemos, este es el primer caso de empiema pleural causado por Trichomona hominis reportado en México (AU)

Pleural empyema is one of the complications of lower respiratory tract infections and is characterized by the presence of pus on thoracentesis. Trichomonas hominis is rarely associated with empyema as the causative agent. In this article we present the case of a 39-year-old woman who developed an empyema caused by T. hominis, as well as a review of the available literature on this rare infection. To the best of our knowledge, this is the first case of pleural empyema caused by Trichomona hominis reported in Mexico (AU)

Evaluation of the RAPID score as a predictor of postoperative morbidity and mortality in patients undergoing pulmonary decortication for stage III pleural empyema

Abstract Objective: This study aims to correlate the RAPID score with the 3-month survival and surgical results of patients undergoing lung decortication with stage III pleural empyema. Methods: This was a retrospective study with the population of patients with pleural empyema who underwent pulmonary decortication between January 2019 and June 2022. Data were collected from the institution's database, and patients were classified as low, medium, and high risk according to the RAPID score. The primary outcome was 3-month mortality. Secondary outcomes were the length of hospital stay, readmission rate, and the need for pleural re-intervention. Results: Of the 34 patients with pleural empyema, according to the RAPID score, patients were stratified into low risk (23.5 %), medium risk (47.1 %), and high risk (29.4 %). The high-risk group had a 3-month mortality of 40 %, while the moderate-risk group hada 6.25 % and the low-risk group had no deaths within 90days, confirmingagood correlation with the RAPID score (p < 0.05). Sensitivity and specificity for the primary outcome in the high-risk score were 80.0 % and 79.3%, respectively. The secondary outcomes did not reach statistical significance. Conclusions: In this retrospective series, the RAPID score had a good correlation with 3-month mortality in patients undergoing lung decortication. The morbidity indicators did not reach statistical significance. The present data justifies further studies to explore the capacity of the RAPID score to be used as a selection tool for treatment modality in patients with stage III pleural empyema.

Management of pediatric pleural empyema: a national survey of pediatric surgeons in Brazil

ABSTRACT Objective: To identify how pediatric surgeons manage children with pneumonia and parapneumonic pleural effusion in Brazil. Methods: An online cross-sectional survey with 27 questions was applied to pediatric surgeons in Brazil through the Brazilian Association of Pediatric Surgery. The questionnaire had questions about type of treatment, exams, hospital structure, and epidemiological data. Results: A total of 131 respondents completed the questionnaire. The mean age of respondents was 44 ± 11 years, and more than half (51%) had been practicing pediatric surgery for more than 10 years. The majority of respondents (33.6%) reported performing chest drainage and fibrinolysis when facing a case of fibrinopurulent parapneumonic pleural effusion. A preference for video-assisted thoracic surgery instead of chest drainage plus fibrinolysis was noted only in the Northeast region. Conclusions: Chest drainage plus fibrinolysis was the treatment adopted by most of the respondents in this Brazilian sample. There was a preference for large drains; in contrast, smaller drains were preferred by those who perform chest drainage plus fibrinolysis. Respondents would rather change treatment when facing treatment failure or in critically ill children.

Multilevel spinal epidural empyema: series of clinical cases and bibliographic / Empiema epidural espinhal multinível: série de casos clínicos e revisão bibliográfica / Empiema epidural espinal multinivel: serie de casos clínicos y revisión bibliográfica

ABSTRACT: Multilevel spinal epidural empyema (SEE) is a rare and serious infection of the spine with a high rate of morbidity and mortality. Although abscesses or empyema of the spine sector are well studied, this pathology is surprising due to its rarity and diagnostic and therapeutic challenge. It stands out for being more common in adulthood and in males and is associated with predisposing pathologies. The bacteriological agent responsible in most cases is Staphylococcus aureus. Early treatment is essential and is based on two pillars: antibiotic therapy and decompressive surgery. We present two clinical cases with multilevel involvement that evolved favorably both infectiously and neurologically without causing spine instability and we carried out a bibliographic review of the subject. Level of Evidence IV; Case Report.

RESUMO: O empiema epidural espinhal multinível (EEE) e uma infecção rara e grave da coluna vertebral, com alta taxa de morbidade e mortalidade. Embora os abscessos ou empiemas de um setor da coluna vertebral sejam bem estudados, esta patologia surpreende pela sua raridade e desafio diagnóstico e terapêutico. Destaca-se por ser mais comum na idade adulta, no sexo masculino, e estar associada a patologias predisponentes. O agente bacteriológico responsável na maioria dos casos e o Staphylococcus aureus. O tratamento precoce e essencial e baseia-se em dois pilares: antibioticoterapia e cirurgia descompressiva. Apresentamos dois casos clínicos com envolvimento multinível que evoluíram favoravelmente tanto infecciosa quanto neurologicamente sem causar instabilidade da coluna vertebral e realizamos uma revisão bibliográfica do assunto. Nível de Evidencia IV; Estudo de Caso-controle.

Síndrome de compresión medular de etiología infecciosa

El síndrome de compresión medular es una urgencia neuroquirúrgica debido a que un diagnóstico precoz y un tratamiento temprano podría revertir las incapacitantes secuelas ocasionadas por esta enfermedad. Las causas de este síndrome pueden ser traumática, metastásica, infecciosa y vascular (hematomas). La etiología infecciosa no es frecuente y el principal germen involucrado suele ser Staphylococcus aureus. A continuación presentamos el caso de una paciente de 58 años con síndrome de compresión medular de etiología infecciosa quien fue ingresada en el Servicio de Clínica Médica del Centro Médico Nacional.

Spinal cord compression syndrome is a neurosurgical emergency because early diagnosis and early treatment could reverse the disabling consequences caused by this disease. The causes of this syndrome can be traumatic, metastatic, infectious, and vascular (hematomas). Infectious etiology is not frequent and the main germ involved is usually Staphylococcus aureus. Below we present the case of a 58-year-old patient with spinal cord compression syndrome of infectious etiology who was admitted to the Medical Clinic Service of the National Medical Center.

Massive pleural empyema secondary to amoebic liver abscess in a child / Empiema pleural masivo secundario a absceso hepático amebiano en un niño

Abstract Background: Pleural empyema secondary to a ruptured amoebic liver abscess is a rare complication in the pediatric population. Case report: We report the case of a 13-year-old male with right flank abdominal pain, productive cough with foul-smelling sputum, fever, and respiratory distress. Physical examination revealed breathlessness, decreased vesicular murmur in the right hemithorax, abdominal distension, hepatomegaly, and lower limb edema. Laboratory tests revealed mild anemia, leukocytosis without eosinophilia, elevated alkaline phosphatase, hypoalbuminemia, and positive immunoglobulin G antibodies against Entamoeba histolytica in pleural fluid. He required a chest tube and treatment with metronidazole. After 2 months of follow-up, the abscesses disappeared, and the empyema decreased. Conclusions: Massive pleural empyema secondary to a ruptured liver abscess is a rare complication. The epidemiological link associated with the symptoms and serological tests can help in the diagnosis.

Resumen Introducción: El empiema pleural secundario a ruptura de absceso amebiano hepático es una complicación poco frecuente en la población pediátrica. Caso clínico: Se reporta el caso de un paciente de sexo masculino de 13 años que presentó dolor abdominal en flanco derecho, tos productiva con esputo de mal olor, fiebre y dificultad respiratoria. Al examen físico se encontró amplexación y murmullo vesicular disminuido en hemitórax derecho, distensión abdominal, hepatomegalia y edema de miembros inferiores. Los resultados del laboratorio evidenciaron anemia leve, leucocitosis sin eosinofilia, elevación de fosfatasa alcalina, hipoalbuminemia y anticuerpos IgG contra Entamoeba histolytica positivo en líquido pleural. Requirió tubo de drenaje torácico y tratamiento con metronidazol. A los dos meses de seguimiento los abscesos desaparecieron y el empiema disminuyó. Conclusiones: El empiema pleural masivo secundario a ruptura de absceso hepático es una complicación poco frecuente. El nexo epidemiológico asociado con la sintomatología y pruebas serológicas pueden ser de ayuda en el diagnóstico.

Double Outlet Right Ventricle Infective Endocarditis: A Rare Combination and a Therapeutic Challenge

Infective endocarditis involving the right side of the heart occurs rarely and often involves the tricuspid valve. The isolated pulmonary valve infective endocarditis (IPVIE) is a less common condition that occurs in specific population. The double outlet right ventricle (DORV) is an unusual congenital heart disease. The association of DORV and IPVIE darkens the prognosis. We report two cases of the association of DORV and IPVIE. The transthoracic echocardiography (TTE) is the base to the diagnosis. Right sided infective endocarditis in the lack of a guided strategy remains a therapeutic challenge.

Empiema pleural por Parvimonas micra en un paciente inmunocompetente: reporte de un caso / Pleural empyema by Parvimonas micra in an immunocompetent patient: a case report

Se presenta el caso de un paciente joven inmunocompetente, con antecedente de tuberculosis pulmonar, que acude al hospital por un cuadro clínico subagudo de fiebre persistente, baja de peso, disnea y abolición del murmullo vesicular. La tomografía de tórax mostró un extenso empiema en hemitórax izquierdo. Se le toman muestras para detección de gérmenes comunes y se le colocan un tubo de drenaje torácico y se inicia antibioticoterapia. La prueba de MALDI-TOF MS identificó a Parvimonas micra, una bacteria anaerobia, comensal de la flora oral, asociado a periodontitis severa, escasamente reportado en empiema pleural, especialmente, en personas inmunocompetentes. En la evaluación odontológica se realizó el diagnóstico de gingivitis y pericoronaritis de la tercera molar. El paciente evolucionó favorablemente. Se sugiere que, en casos de empiemas pleurales subagudos o crónicos, se debe considerar, además de las micobacterias, como agente etiológico al Parvimonas micra, y optar por exámenes como MALDI-TOF MS o secuenciamiento del 16S rRNA, colocación de tubo de tórax, cobertura antibiótica empírica y evaluación odontológica.

We present the case of a young immunocompetent patient, with a history of pulmonary tuberculosis, who attended the hospital with a subacute clinical picture of persistent fever, weight loss, dyspnea and abolition of vesicular murmur. Chest CT scan showed an extensive empyema in the left hemithorax. Samples were taken for detection of common germs. Then, a chest drainage tube was placed and antibiotic therapy started. The MALDI-TOF MS test identified Parvimonas micra, an anaerobic bacterium, commensal to the oral flora, associated with severe periodontitis, but rarely reported in cases of pleural empyema, especially in immunocompetent patients. Gingivitis and pericoronaritis of the third molar were diagnosed during oral evaluation. The patient progressed favorably. Parvimonas micra should be considered as a possible etiological agent in cases of subacute or chronic pleural empyema, in addition to mycobacteria. Tests such as MALDI-TOF MS or 16S rRNA sequencing, chest tube placement, empirical antibiotic coverage and an adequate oral evaluation should be considered in these cases.

Reverse partial pulmonary resection: a new surgical approach for pediatric pulmonary cysts / 南方医科大学学报

OBJECTIVE@#To evaluate the safety and efficacy of reverse partial lung resection for treatment of pediatric pulmonary cysts combined with lung abscesses or thoracic abscess.@*METHODS@#We retrospectively analyzed the clinical data of children undergoing reverse partial lung resection for complex pulmonary cysts in our hospital between June, 2020 and June, 2021.During the surgery, the patients lay in a lateral position, and a 3-5 cm intercostal incision was made at the center of the lesion, through which the pleura was incised and the fluid or necrotic tissues were removed.The anesthesiologist was instructed to aspirate the sputum in the trachea to prevent entry of the necrotic tissues in the trachea.The cystic lung tissue was separated till reaching normal lung tissue on the hilar side.The proximal end of the striated tissue in the lesion was first double ligated with No.4 silk thread, the distal end was disconnected, and the proximal end was reinforced with continuous sutures with 4-0 Prolene thread.The compromised lung tissues were separated, and the thoracic cavity was thoroughly flushed followed by pulmonary inflation, air leakage management and incision suture.@*RESULTS@#Sixteen children aged from 3 day to 2 years underwent the surgery, including 3 with simple pulmonary cysts, 11 with pulmonary cysts combined with pulmonary or thoracic abscess, 1 with pulmonary cysts combined with tension pneumothorax and left upper lung bronchial defect, and 1 with pulmonary herpes combined with brain tissue heterotaxy.All the operations were completed smoothly, with a mean operation time of 129 min, an mean hospital stay of 11 days, and a mean drainage removal time of 7 days.All the children recovered well after the operation, and 11 of them had mild air leakage.None of the children had serious complications or residual lesions or experienced recurrence of infection after the operation.@*CONCLUSION@#Reverse partial lung resection is safe and less invasive for treatment of complex pediatric pulmonary cysts complicated by infections.

Intrapleural Urokinase and Antibiotic Therapy for Empyema after In Situ Reconstruction of the Aorta and Lobectomy for Aortopulmonary Fistula due to Thoracic Aortic Aneurysm Rupture / 日本心臓血管外科学会雑誌

A 62-year-old man presented with hemoptysis and hoarseness. He was diagnosed with an aortopulmonary fistula due to a thoracic aortic aneurysm rupture and was referred to our department. Emergency in-situ reconstruction of the aorta and pulmonary lobectomy were performed. Nine days postoperative, he developed empyema. Intrapleural urokinase and antibiotic therapy were selected as management instead of a video-assisted thoracoscopic debridement and decortication due to his worsening condition. The treatment was successful, and he was discharged from the hospital without any further complications. This study highlights the benefit of intrapleural administration of urokinase and antibiotics in patients with acute empyema, when surgical treatment is inappropriate.

Ensayo controlado y aleatorizado del uso de Heberkinasa® en el derrame pleural paraneumónico en niños / Randomized Controlled Trial of the Use of Heberkinase® in Parapneumonic Pleural Effusion in Children

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)

Correlación fisiopatológica, diagnóstica y terapéutica en el derrame pleural paraneumónico / Pathophysiological, diagnostic and therapeutic correlation in parapneumonic pleural effusion

Introducción: La inflamación de la pleura desencadenada por bacterias y mediada por citocinas, aumenta la permeabilidad vascular y produce vasodilatación, lo cual genera desequilibrio entre la producción de líquido pleural y su capacidad de reabsorción por eficientes mecanismos fisiológicos. La condición anterior conduce al desarrollo de derrame pleural paraneumónico. Objetivo: Exponer la importancia de la correlación fisiopatológica y diagnóstica con los pilares fundamentales de actuación terapéutica en el derrame pleural paraneumónico. Métodos: Revisión en PubMed y Google Scholar de artículos publicados hasta abril de 2021 que abordaran el derrame pleural paraneumónico, su fisiopatología, elementos diagnósticos, tanto clínicos como resultados del estudio del líquido pleural, pruebas de imágenes, y estrategias terapéuticas. Análisis y síntesis de la información: El progreso de una infección pulmonar y la producción de una invasión de gérmenes al espacio pleural favorece la activación de mecanismos que conllevan al acúmulo de fluido, depósito de fibrina y formación de septos. Este proceso patológico se traduce en manifestaciones clínicas, cambios en los valores citoquímicos y resultados microbiológicos en el líquido pleural, que acompañados de signos radiológicos y ecográficos en el tórax, guían la aplicación oportuna de los pilares de tratamiento del derrame pleural paraneumónico. Conclusiones: Ante un derrame pleural paraneumónico, con tabiques o partículas en suspensión en la ecografía de tórax, hallazgo de fibrina, líquido turbio o pus en el proceder de colocación del drenaje de tórax, resulta necesario iniciar fibrinólisis intrapleural. Cuando el tratamiento con fibrinolíticos intrapleurales falla, la cirugía video-toracoscópica es el procedimiento quirúrgico de elección(AU)

Introduction: The inflammation of the pleura triggered by bacteria and mediated by cytokines, increases vascular permeability and produces vasodilation, which generates imbalance between the production of pleural fluid and its resorption capacity by efficient physiological mechanisms. The above condition leads to the development of parapneumonic pleural effusion. Objective: To expose the importance of the pathophysiological and diagnostic correlation with the fundamental pillars of therapeutic action in parapneumonic pleural effusion. Methods: Review in PubMed and Google Scholar of articles published until April 2021 that addressed parapneumonic pleural effusion, its pathophysiology, diagnostic elements, both clinical and results of the pleural fluid study, imaging tests, and therapeutic strategies. Analysis and synthesis of information: The progress of a lung infection and the production of an invasion of germs into the pleural space favors the activation of mechanisms that lead to the accumulation of fluid, fibrin deposition and formation of septa. This pathological process results in clinical manifestations, changes in cytochemical values and microbiological results in the pleural fluid, which accompanied by radiological and ultrasound signs in the chest, guide the timely application of the pillars of treatment of parapneumonic pleural effusion. Conclusions: In the event of a parapneumonic pleural effusion, with septums or particles in suspension on chest ultrasound, finding fibrin, turbid fluid or pus in the procedure of placement of the chest drain, it is necessary to initiate intrapleural fibrinolytic. When treatment with intrapleural fibrinolytics fails, video-thoracoscopic surgery is the surgical procedure of choice(AU)

Rare Presentation of Morganella morganii Microorganism as Epidural and Subdural Empyema / Apresentação rara de Morganella morganii Microrganismo como Empiema Epidural e Subdural

Background Morganella morganii is a gram-negative bacterium that rarely infects the central nervous system (CNS). Few reports described such an infection in the CNS. We present a case of extremely invasive M. morganii infection in the CNS. In addition, we performed a literature review of M. morganii infection in the CNS. Case report A 53-year-old male was admitted to the hospital due to fever, general weakness, and left-sided facial muscle twitching. He had a history of diabetes mellitus, hypertension, brain tumor, and epilepsy. Multiple left frontal scalp ulcers were revealed. In addition, a computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed a left side epidural abscess and subdural empyema. Moreover, the patient had left frontal bone osteomyelitis. The next day, the patient underwent craniectomy, was transferred to the intensive care unit and started an empirical antibiotic course. Morganella morganii was identified from the infected scalp ulcers. On the 13th day, the patient passed away due to uncontrolled status epilepticus. Conclusion M. morganii can cause isolated or multiple types of CNS infections, including brain abscess, meningitis, and subdural empyema. The mortality rate may differ according to age and to the use of surgical evacuation.

Introdução Morganella morganii é uma bactéria gram-negativa que raramente infecta o sistema nervoso central (SNC). Poucos relatos descreveram tal infecção no SNC. Apresentamos um caso de infecção extremamente invasiva por M. morganii no SNC. Além disso, realizamos uma revisão da literatura sobre a infecção por M. morganii no SNC. Relato de caso Um homem de 53 anos foi admitido no hospital devido a febre, fraqueza geral e espasmos da musculatura facial do lado esquerdo. Ele tinha história de diabetes mellitus, hipertensão, tumor cerebral e epilepsia. Múltiplas úlceras no couro cabeludo frontal esquerdo foram reveladas. Além disso, uma tomografia computadorizada (TC) e uma ressonância magnética (RM) revelaram um abscesso epidural do lado esquerdo e empiema subdural. Além disso, o paciente apresentava osteomielite do osso frontal esquerdo. No dia seguinte, o paciente foi submetido à craniectomia, foi transferido para a unidade de terapia intensiva e iniciou curso empírico de antibiótico. Morganella morganii foi identificada a partir das úlceras do couro cabeludo infectadas. No 13° dia, o paciente faleceu devido a estado de mal epiléptico não controlado. Conclusão M. morganii pode causar tipos isolados ou múltiplos de infecções do SNC, incluindo abscesso cerebral, meningite e empiema subdural. A taxa de mortalidade pode diferir de acordo com a idade e com o uso da evacuação cirúrgica.

Fatal case of subdural empyema caused by Campylobacter rectus and Slackia exigua

ABSTRACT We report a fatal subdural empyema caused by Campylobacter rectus in a 66-year-old female who developed acute onset of confusion, dysarthria, and paresis in her left extremities. A CT scan showed hypodensity in a crescentic formation with a mild mid-line shift. She had a bruise on her forehead caused by a fall several days before admission, which initially raised subdural hematoma (SDH) diagnosis, and a burr hole procedure was planned. However, her condition deteriorated on the admission night, and she died before dawn. An autopsy revealed that she had subdural empyema (SDE) caused by Campylobacter rectus and Slackia exigua. Both microorganisms are oral microorganisms that rarely cause extra-oral infection. In our case, head trauma caused a skull bone fracture, and sinus infection might have expanded to the subdural space causing SDE. CT/MRI findings were not typical for either SDH or SDE. Early recognition of subdural empyema and prompt initiation of treatment with antibiotics and surgical drainage is essential for cases of SDE. We present our case and a review of four reported cases.

Factores de riesgo de neumonía adquirida en la comunidad, complicada con empiema pleural

Introducción: la neumonía es la principal causa de derrame pleural (DP) en los niños. Un elevado número de los pacientes ingresan a las unidades de cuidados intensivos pediátricos con derrame pleural paraneumónico (DPP), terminando en el empiema pleural. Objetivo: identificar los factores de riesgo que influyen de forma independiente en la aparición de neumonía adquirida en la comunidad, complicada con empiema pleural. Métodos: se realizó un estudio observacional analítico de casos y controles, se seleccionaron 30 casos y 90 controles. Con una proporción de 1:3. Se realizó el análisis estadístico univariado y multivariado. Resultados: en el análisis univariado, la edad menor de 5 años y el sexo masculino se mostraron sin influencia estadísticamente significativa, mientras que el multivariado mostró que el factor con independencia más importante fue el uso previo de antimicrobiano (OR 6,329 ajustado IC 95% 2,764-8,678), seguido del diagnóstico tardío (OR ajustado 5,492IC 95% 2,559-8,522) y la presencia de comorbilidad (OR ajustado 4,341 IC 95% 2,321−7,529) de manera similar. Conclusiones: los factores de mayor riesgo que contribuyeron al riesgo de desarrollar la neumonía complicada con empiema pleural fueron el uso previo de antimicrobiano, el diagnóstico tardío de empiema y la presencia de comorbilidad.

Empiema necessitatis por Campylobacter rectus. Identificación rápida por MALDI-TOF MS / Empyema necessitatis caused by Campylobacter rectus. Rapid identification by MALDI-TOF MS

Resumen El empiema necessitatis (EN) constituye una muy rara complicación de un empiema pleural en el cual la infección se extiende a los tejidos blandos adyacentes. La etiología por anaerobios es muy infrecuente y se da en el curso de infecciones crónicas. Se presenta el primer caso de empiema necessitatis por Campylobacter rectus. La identificación de este agente se efectuó por espectrometría de masas (MALDI-TOF MS) y su sensibilidad antimicrobiana se determinó por el método epsilométrico.

Abstract Empyema necessitatis (EN) is a very rare complication of a pleural empyema, in which the infection extends to adjacent soft tissues. Anaerobic bacteria are very rare etiologic agents of EN, which occurs in the course of chronic infections. We present the first case of empyema necessitatis caused by Campylobacter rectus. Bacterial identification was carried out by mass spectrometry (MALDI-TOF MS) and antimicrobial susceptibility was determined by the epsilometer method.

Management of parapneumonic effusion and thoracic empyema with intrapleural instillation of 2-mercaptoethane sulfonate sodium and conservative approach – A comparative study

Background: The aim of pleural effusion management is to provide symptomatic relief by draining excessive fluid in the pleural space and stable the patient before the surgical and therapeutic intervention of underlying disease. Intrapleural fibrinolytic therapy is an effectively adjunct to improve the drainage of loculated effusion in complicated empyema especially in cases who fail chest tube drainage. Aim and Objectives: The aim of the study was to compare the efficacy of intrapleural instillation of 2-mercaptoethane sulfonate sodium (MESNA) and conservative approach in the management of loculated parapneumonic effusion and thoracic empyema. Materials and Methods: A total of 50 cases with loculated parapneumonic effusion and empyema above 21 years of age were recruited. Cases were randomly divided into two groups, that is, Group 1 managed with intrapleural instillation of MESNA for adhesiolysis of loculations through tube thoracostomy and Group 2 managed with conservative approach through tube thoracostomy. Results: Effusion in 84–80% and empyema in 16–20% were observed in Group 1 and Group 2, respectively. The mean value of number of days in ICD was 14.98 days in Group 1 and 19.5 days in Group 2. The amount of fluid drained (125.3–95.6 ml) and mean duration of hospital stay (22.2–28.5) was statistically significant between study groups. No adverse complications were noticed; however, cough and pain at the site of injection were reported in two cases each. Around, 32–64% cases required surgical intervention in Group 1 and Group 2, respectively. Conclusion: The intrapleural fibrinolytic therapy by 2-MESNA has better efficacy than conservative thoracostomy. The MENSA has better outcome in regard to breaking loculations, limited requirement of surgical intervention, less duration of hospital stay, and faster absorption of pleural fluid in effusion and empyema.

Fístula pleurocutánea secundaria a empiema

RESUMEN Introducción: La fístula pleurocutánea es una rara entidad que aparece como complicación de traumatismos torácicos, de la cirugía pleuro pulmonar o procesos infecciosos que afectan el espacio pleural tales como el empiema. Objetivo: Describir hallazgos clínico imagenológicos de un paciente con fístula pleurocutánea secundaria a empiema. Caso clínico: Paciente masculino de 56 años de edad, blanco, de procedencia rural, fumador inveterado y consumidor habitual de bebidas alcohólicas, con antecedentes patológicos personales de neumonías extrahospitalarias que requirieron hospitalización por aparición de complicaciones pleurales. Acudió al servicio de medicina interna del Hospital "Vladimir Ilich Lenin" porque desde hacía dos meses notó un agujero debajo de la axila derecha, por el cual drenaba líquido fétido. Los estudios imagenológicos realizados incluyeron fistulografía y tomografía axial computarizada. El diagnóstico clínico imagenológico fue fístula pleurocutánea. El paciente ingresó en el servicio de Medicina para cumplir tratamiento antimicrobiano; se le realizaron procederes intervencionistas diagnósticos y terapéuticos; evolucionó con complicaciones y falleció. La fístula pleurocutánea es una complicación de difícil manejo para el médico de asistencia, pues no siempre suelen resolver con los métodos tradicionales de tratamiento y requiere períodos prolongados de curación. Conclusiones: La fístula pleurocutánea es infrecuente y de difícil manejo. El diagnóstico de certeza se realiza a través de la fistulografía.

ABSTRACT Introduction: Pleurocutaneous fistula is a rare entity that appears as a complication of thoracic trauma, pleuro-pulmonary surgery or infectious processes that affect the pleural space such as empyema. Objective: To describe clinical imaging findings of a patient with pleurocutaneous fistula secondary to empyema. Clinical case: 56-year-old white male patient of rural origin, inveterate smoker and habitual consumer of alcoholic beverages, with a personal pathological history of community-acquired pneumonia that required hospitalization due to the onset of pleural complications. He went to the internal medicine service of the "Vladimir Ilyich Lenin" Hospital because for two months he had noticed a hole under his right armpit, through which he was draining foul-smelling fluid. The imaging studies included fistulography and computerized axial tomography. The clinical imaging diagnosis was pleurocutaneous fistula. The patient was admitted to the Medicine service for antimicrobial treatment; diagnostic and therapeutic interventionist procedures were performed; he evolved with complications and passed away. Pleurocutaneous fistula is a complication difficult to manage for the attending physician, as it does not always usually resolve with traditional methods of treatment and requires prolonged healing periods. Conclusions: Pleurocutaneous fistula is rare and difficult to manage. The certainty diagnosis is made through fistulography.
