RESUMO

Se presenta el caso de un absceso cerebral causado por Haemophilus infl uenzae tipo e, en un paciente de 12 años con síndrome de Apert. El síndrome de Apert se caracteriza por el cierre prematuro de las suturas craneales. En 2010, el paciente presentó traumatismo craneano en región frontal, fractura y fístula de líquido cefalorraquídeo. En febrero de 2013 consultó por fi ebre, vómitos y convulsión tónica clónica generalizada, con deterioro progresivo del sensorio. La tomografía axial computarizada mostró una lesión frontal derecha, edema perilesional, leve dilatación ventricular y pansinusitis. Se diagnosticó absceso cerebral con pioventriculitis y se realizó drenaje. Se obtuvo desarrollo de un cocobacilo gram negativo, que fue identifi cado como H. infl uenzae serotipo e. Se realizó tratamiento empírico con meropenem (120 mg/kg/día) y vancomicina (60 mg/kg/día). Luego del resultado del cultivo, se rotó a ceftriaxona (100 mg/kg/día) y metronidazol (500 mg/8 h). El paciente cumplió 8 semanas de tratamiento y se observó evolución favorable


We report a case of a brain abscess caused by Haemophilus infl uenzae type e in a 12 year-old patient suffering from Apert syndrome. Apert syndrome is characterized by the premature closure of cranial sutures. In 2010 the patient suffered head trauma in the frontal area with cranial fracture and a cerebrospinal fl uid fi stula. In February 2013 he was admitted to hospital with fever, vomiting and generalized tonic-clonic seizure with deteriorating mental status/progressive sensory impairment. The computerized axial tomographic scan showed a right frontal lesion, perilesional edema, mild ventricular dilatation and pansinusitis. A brain abscess was diagnosed and drained. The clinical sample was then cultured. A gram negative coccobacillus was isolated and identifi ed as Haemophilus infl uenzae serotype e. Empirical treatment was started with meropenem (120 mg/kg/day) and vancomycin (60 mg/kg/day), which was later switched to ceftriaxone (100 mg/kg/day) and metronidazole (500 mg/8 h) after culture results arrived. The patient was discharged in good clinical condition

RESUMO

We report a case of a brain abscess caused by Haemophilus influenzae type e in a 12 year-old patient suffering from Apert syndrome. Apert syndrome is characterized by the premature closure of cranial sutures. In 2010 the patient suffered head trauma in the frontal area with cranial fracture and a cerebrospinal fluid fistula. In February 2013 he was admitted to hospital with fever, vomiting and generalized tonic-clonic seizure with deteriorating mental status/progressive sensory impairment. The computerized axial tomographic scan showed a right frontal lesion, perilesional edema, mild ventricular dilatation and pansinusitis. A brain abscess was diagnosed and drained.

RESUMO

La introducción de la vacuna contra Haemophilus influenzae tipo b en los programas de inmunización de muchos países produjo una reducción marcada en la incidencia de enfermedad invasiva causada por este serotipo y en su portación y un incremento de otros tipos capsulares y de aislamientos no capsulados. Se estudiaron 313 aislamientos de H. influenzae recuperados de sitio estéril, provenientes de pacientes pediátricos y adultos con enfermedad invasiva atendidos en 90 hospitales de la Red Nacional de Laboratorios para Meningitis e Infecciones Respiratorias Agudas Bacterianas durante el período 2005-2010. Las patologías más frecuentes fueron neumonía, 40,3 % (n = 126), meningitis, 30,0 % (n = 94) y bacteriemia, 26,5 % (n = 83). En los pacientes pediátricos (n = 279), la mayor frecuencia de aislamientos correspondió a menores de 2 años, 74,5 % (n = 208). Con respecto a la distribución de tipos, el 61,3 %, correspondió a H. influenzae no capsulados (n = 192); el 20,1 % al b (n = 63); 11,2 % al a (n = 35); 4,8 % al f y 2,6 % a otros. En meningitis predominaron H. influenzae capsulados mientras que en neumonía y bacteriemia resultaron dominantes los tipos no capsulados. Se determinó el biotipo en 306 aislamientos. Todos los aislamientos de tipo a correspondieron al biotipo II; el 66,7 % de los tipo b pertenecieron al biotipo I. Mediante las técnicas de aglutinación en lámina y PCR se estudiaron 220 aislamientos; la concordancia entre ambas fue de 0,982 (IC: 0,92-1,00). En el último año se encontró un aumento significativo del tipo b, lo cual indica la importancia de mantener la vigilancia clínica y laboratorial de la enfermedad invasiva por H. influenzae.(AU)


The introduction of the Haemophilus influenzae type b vaccine in the immunization programs of many countries has greatly reduced this invasive disease and the carriage caused by this serotype, also increasing other capsular types and non-capsular isolations. There were 313 isolations of H. influenzae under study, which were recovered from a sterile site coming from pediatric and adult patients carrying the invasive disease. Patients were treated at 90 different hospitals belonging to the Red Nacional de Laboratorios para Meningitis e Infecciones Respiratorias Agudas Bacterianas (National Lab Network for Meningitis and Acute Bacterial Respiratory Infections) from 2005 to 2010 for the following disorders: pneumonia, 40.3% (n = 126), meningitis, 30.0% (n = 94) and bacteremia, 26.5% (n = 83). In pediatric patients (n = 279), the highest frequency of isolations corresponded to children under the age of 2 years, 74.5% (n = 208). Regarding type distribution, 61.3% corresponded to non-capsular H. influenzae (n = 192), 20.1% to type b (n = 63), 11.2% to type a (n = 35), 4.8% to type f, and 2.6% to other types. Capsular H. influenzae was predominant in meningitis whereas non-capsular H. influenzae in pneumonia and bacteremia. The biotype was determined in 306 isolations. The totality (100%) of type a (n = 35) was biotype II whereas 66.7% of type b (n = 63) was biotype I. Slide agglutination and PCR tests were used in 220 isolations. There was a match of 0.982 (IC: 0.92-1.00) between them. During the last year, there was a great increase in type b, showing the importance of clinical and laboratory-based surveillance of the invasive disease caused by H. influenzae.(AU)

RESUMO

Samples of pediatric patients suspected of tuberculosis and cared for at Hospital Piñero during the 2004-2008 period were analyzed according to epidemiological and clinical criteria. The bacteriological contribution was evaluated to confirm the disease diagnosis. A descriptive retrospective analysis of the cases was done. A total of 8409 samples were received for mycobacterial culture: 1542 (18%) of which were pediatric and distributed as follows: 1407 (91%), pulmonary and 135 (9%), extra-pulmonary. The sample examination included staining for acid-fast bacilli, culture, identification and drug susceptibility testing. The following are the results of analized demographic variables: Nationality: 1218 Argentinean (79%), 247 foreigners (16%) and 77, not disclosed (5%); Gender: 787 female (51%) and 755 male (49%). Patients were grouped according to age into: Group A, 0 to 4 years 674 (45%); Group B, 5-9 years 354 (24%) and Group C, 10-15 years 464 (31%). Morbidity causes associated with the disease were mainly malnutrition and infection by Human Immunodeficiency Virus. Staining for acid-fast bacilli was positive in 41 samples (2.6%) and 84 cultures resulted positive (5.4%), 78 (93%) of which were pulmonary and 6 (7%) extra-pulmonary samples. All the strains were identified as Mycobacterium tuberculosis. Isolates were susceptible to streptomycin, isoniazid, rifampicin, and ethambutol, except for one strain that was resistant both to ethambutol and streptomycin, and another one which was resistant to isoniazid. Bacteriological confirmation of pediatric tuberculosisis is rarely achieved due to the predominantly paucibacillary nature of the disease in children (5% in our study), but plays a fundamental role in diagnosis accuracy, allowing the identification and susceptibility testing of the strain.
