RESUMO
La pericarditis purulenta es una patología poco frecuente pero que conlleva alta mortalidad. En la era pre antibióticos, se observaba en pacientes con neumonía complicada y las cocáceas gram positivas eran los gérmenes frecuentemente involucrados. Por otro lado, la pericarditis tuberculosa representa el 1% del total de casos de tuberculosis, aunque es frecuente zonas endémicas, principalmente asociada a la infección por el virus de la inmunodeficiencia humana (VIH). Presentamos el caso de un paciente de 19 años, en situación calle, infectado con VIH, con diagnóstico de pericarditis purulenta, donde se demostró la co-infección de Mycobacterium tuberculosis y Streptecoccus pneumoniae en el pericardio. La pericarditis purulenta polimicrobiana es poco frecuente y la co-infección por los gérmenes mencionados es anecdótica. A pesar del tratamiento antimicrobiano, el aseo quirúrgico, los esteroides y la fibrinolisis intrapericárdica, esta patología tiene un pronóstico ominoso, en parte, debido a la condición basal de los enfermos que la padecen.
Purulent pericarditis is a rare disease with a high mortality rate. In the pre-antibiotic era it was observed as a complication in patients with pneumonia. Gram-positive coccaceae were the most commonly implicated bacteria. Tuberculous pericarditis represents 1% of all tuberculosis (TBC) cases, although it is common in endemic areas, associated with human immunodeficiency virus (HIV) infection. We present the case of a 19-year-old homeless, admitted with HIV and malnutrition, diagnosed with purulent pericarditis. Mycobacterium tuberculosis and Streptococcus pneumoniae were found as a cause of purulent pericarditis. Polymicrobial purulent pericarditis is a rare condition and co-infection with the bacteria previously mentioned is merely anecdotal. Despite antimicrobial treatment, surgical management, steroids, and intrapericardial fibrinolysis, this pathology has an ominous prognosis, due in part to the pre-existing condition of these patients.

INTRODUCTION: Sepsis is a serious problem in felines with a mortality rate ranging from 29-79%. Neisseria spp. is considered a commensal microorganism of the oral cavity of dogs and cats and is usually isolated from human wounds resulting from bites of these animals. CASE REPORT: The present report describes clinical, imaging and laboratory findings of a feline with sepsis wherein commensal and multidrug-resistant (MDR) Neisseria spp. was isolated. The feline presented a history of four days of anorexia, dyspnea, prostration, and, pericardial, pleural and abdominal effusions. Pericardiocentesis was performed and hemorrhagic exudate was observed. The animal died after 11 days of treatment with gentamicin and amoxicillin combined with clavulanic acid. During necropsy, the abdominal cavity was found to be filled with greenish-yellow content and the pericardial sac was thickened with a large amount of purulent secretion. Histopathology revealed sepsis with necrotizing suppurative pericarditis, diffuse mononuclear pneumonia and necrotic pleuritis, leading to secondary bacterial infection. CONCLUSIONS: Commensal Neisseria spp. are important zoonotic bacteria, which trigger a serious disease in felines. However, it has not been reported to cause sepsis with pneumonia, suppurative necrotizing pericarditis and pericardial effusion.

Ventricular pseudoaneurysms are very unusual in children. A six-year-old child developed left ventricular pseudoaneurysm associated with methicillin-sensitive Staphylococcus aureus. The patient responded favorably to antibiotic therapy and ventriculoplasty through an unconventional surgery due to the constrictive pericarditis.

RESUMO Objetivo: Relatar um caso raro de uma criança com meningite associada a pericardite na doença pneumocócica invasiva. Descrição do caso: Este relato descreve uma evolução clínica desfavorável de um lactente feminino de 6 meses de idade, previamente hígido, que apresentou inicialmente sintomas respiratórios e febre. A radiografia de tórax revelou um aumento da área cardíaca sem alterações radiográficas nos pulmões. Após a identificação do derrame pericárdico, o paciente apresentou convulsões e entrou em coma. Pneumonia foi descartada durante a investigação clínica. Contudo, foi identificado Streptococcus pneumoniae nas culturas de líquor e sangue. O exame neurológico inicial foi compatível com morte encefálica, posteriormente confirmada pelo protocolo. Comentários: A pericardite purulenta tornou-se uma complicação rara da doença pneumocócica invasiva desde o advento da terapia antibiótica. Pacientes com pneumonia extensa são primariamente predispostos e, mesmo com tratamento adequado e precoce, estão sujeitos a altas taxas de mortalidade. A associação de meningite pneumocócica e pericardite é incomum e, portanto, de difícil diagnóstico. Por isso, uma alta suspeição diagnóstica é necessária para instituir o tratamento precoce e aumentar a sobrevida.
ABSTRACT Objective: To report a rare case of a child with invasive pneumococcal disease that presented meningitis associated with pericarditis. Case description: This report describes the unfavorable clinical course of a previously healthy 6-months-old female infant who initially presented symptoms of fever and respiratory problems. A chest X-ray revealed an increased cardiac area with no radiographic changes in the lungs. After identifying a pericardial effusion, the patient experienced seizures and went into coma. Pneumonia was excluded as a possibility during the clinical investigation. However, Streptococcus pneumoniae was identified in the cerebrospinal fluid and blood cultures. An initial neurological examination showed that the patient was brain dead, which was then later confirmed according to protocol. Comments: Purulent pericarditis has become a rare complication of invasive pneumococcal disease since the advent of antibiotic therapy. Patients with extensive pneumonia are primarily predisposed and, even with early and adequate treatment, are prone to high mortality rates. The association of pneumococcal meningitis and pericarditis is uncommon, and therefore difficult to diagnose. As such, diagnostic suspicion must be high in order to institute early treatment and increase survival.

BACKGROUND: Pasteurella multocida type A (PmA) is considered a secondary agent of pneumonia in pigs. The role of PmA as a primary pathogen was investigated by challenging pigs with eight field strains isolated from pneumonia and serositis in six Brazilian states. Eight groups of eight pigs each were intranasally inoculated with different strains of PmA (1.5 mL/nostril of 10e7 CFU/mL). The control group (n = 12) received sterile PBS. The pigs were euthanized by electrocution and necropsied by 5 dpi. Macroscopic lesions were recorded, and swabs and fragments of thoracic and abdominal organs were analyzed by bacteriological and pathological assays. The PmA strains were analyzed for four virulence genes (toxA: toxin; pfhA: adhesion; tbpA and hgbB: iron acquisition) by PCR and sequencing and submitted to multilocus sequence typing (MLST). RESULTS: The eight PmA strains were classified as follows: five as highly pathogenic (HP) for causing necrotic bronchopneumonia and diffuse fibrinous pleuritis and pericarditis; one as low pathogenic for causing only focal bronchopneumonia; and two as nonpathogenic because they did not cause injury to any pig. PCR for the gene pfhA was positive for all five HP isolates. Sequencing demonstrated that the pfhA region of the HP strains comprised four genes: tpsB1, pfhA1, tpsB2 and pfhA2. The low and nonpathogenic strains did not contain the genes tpsB2 and pfhA2. A deletion of four bases was observed in the pfhA gene in the low pathogenic strain, and an insertion of 37 kb of phage DNA was observed in the nonpathogenic strains. MLST clustered the HP isolates in one group and the low and nonpathogenic isolates in another. Only the nonpathogenic isolates matched sequence type 10; the other isolates did not match any type available in the MLST database. CONCLUSIONS: The hypothesis that some PmA strains are primary pathogens and cause disease in pigs without any co-factor was confirmed. The pfhA region, comprising the genes tpsB1, tpsB2, pfhA1 and pfhA2, is related to the pathogenicity of PmA. The HP strains can cause necrotic bronchopneumonia, fibrinous pleuritis and pericarditis in pigs and can be identified by PCR amplification of the gene pfhA2.

ABSTRACT Meningococcal meningitis is a well established potential fatal infection characterized by fever, headache, petechial rash, and vomiting in the majority of cases. However, protean manifestations including abdominal pain, sore throat, diarrhea and cough, even though rare, should not be overlooked. Similarly, although disseminated infection could potentially involve various organ-targets, secondary immune related complications including joints or pericardium should be dealt with caution, since they remain unresponsive to appropriate antibiotic regimens. We hereby report the rare case of an otherwise healthy adult female, presenting with acute abdominal pain masking Neisseria meningitidis serotype B meningitis, later complicated with recurrent reactive pericarditis despite appropriate antibiotic treatment. There follows a review of current literature.

We report the case of a 19-year-old male patient admitted to hospital with fever, asthenia, vomiting, abdominal and chest pains, cough with yellowish sputum, and hypotension. Laboratory tests showed leukocytosis and high creatine phosphokinase levels, without hyperbilirubinaemia or renal failure. The tomographic images of the chest and abdomen showed a right basal pneumonia and acalculous cholecystitis. The electrocardiograms revealed significant characteristics of acute pericarditis. Specific serology for leptospirosis done in the second and third weeks of disease showed positive results. The use of ceftriaxone 1g intravenously, twice a day for 7 days, resulted in an overall clinic improvement. The role of the suspicion index for diagnosis of leptospirosis is emphasized in anicteric patients, as well as the unsuspected possibility of pulmonary, pericardial and gallbladder involvement.

La pericarditis es una complicación conocida pero poco frecuente de la infección meningocócica. La incidencia es de 3% a 19% en todos los grupos etarios, con pocos casos informados en la edad pediátrica. La enfermedad meningocócica diseminada con pericarditis es defnida como pericarditis purulenta con evidencia clínica de meningococemia y meningitis. Se presenta el caso de un lactante de 4 meses con diagnóstico de enfermedad meningocócica diseminada con pericarditis causada por Neisseria meningitidis serogrupo B. Tras el tratamiento antibiótico adecuado, se logró controlar el cuadro séptico y cardiológico. Se resalta el hecho de que la infección meningocócica puede presentar formas clínicas poco frecuentes, lo que puede llevar a difcultades diagnósticas y terapéuticas.
Pericarditis is a well-recognized but uncommon complication of meningococcal infection. The incidence of pericarditis complicating meningococcal disease in all age groups is reported to be 3-19%. There are few cases reported in the paediatric age group. Disseminated meningococcal disease with pericarditis, defned as purulent pericarditis with clinical evidence of disseminated meningococcemia and meningitis. We report the case of a 4-month-old male infant who presented disseminated meningococcal disease with pericarditis caused by Neisseria meningitidis serogroup B. The patient was treated with antibiotic with excellent response. It is important to point out that meningococcal disease may present in unusual forms which may lead to diagnostic and therapeutic diffculties.
