Persistent Bacteremia

To investigate the occurrence and outcome of bacteremia associated with otitis media, charts were reviewed from patients who were 3 to 36 months of age, had temperatures ≥39°C, and were diagnosed with isolated clinical otitis media. A total of 2982 patients were identified. Blood cultures were obtained from 1666 (56%). Of the 1666 patients, who had blood drawn for cultures, 50 (3.0%) had bacteremia. These included 39 with Streptococcus pneumoniae, 4 with Haemophilus influenzae, 2 with Neisseria meningitidis, 3 with Salmonella species, and 2 with Staphylococcus aureus. The incidence of bacteremia increased at higher temperatures, being 1.9% at temperatures ≤40°C and 5.0% at temperatures >40°C. Younger children were more likely to have bacteremia; 3.7% ≤12 months of age, 2.4% 13 to 24 months of age, and 1.9% 25 to 36 months of age had blood culture results that were positive (not significant). Reevaluation of the 50 bacteremic patients showed that 9 patients had continued fever, 3 patients had persistent bacteremia, pneumonia developed in 1 patient, and meningitis developed in 1 patient. It was concluded that (1) 3% of young febrile children with otitis media have bacteremia at the time of evaluation, a rate comparable to that previously reported in children with no focus of infection; (2) the incidence of bacteremia increases at higher temperatures; and (3) most febrile children with otitis media do well. The clinician must therefore weigh the potential benefit of drawing a blood culture to identify children at risk for complications against the inherent cost, inconvenience, and discomfort.

Occult Bacteremia

The potential clinical value of quantitative blood cultures determined by a commercially available lysis-direct plating method was studied in 50 children with either Haemophilus influenzae or Streptococcus pneumoniae bacteremia. The magnitude of bacteremia correlated with the severity of the infection; patients with ≥100 colony-forming units per milliliter were significantly more likely to have meningitis (P < .01, χ2 = 7.5). On the other hand, all patients with S. pneumoniae bacteremia with colony counts lower than 15 colony-forming units per milliliter had "occult bacteremia" with no focus of infection. The data suggest that patients with higher levels of bacteremia have more severe disease. Quantitative blood culture results may be helpful in identifying which children are at risk for invasive disease.

Introduction: Pneumonia is the single largest infectious cause of death in children worldwide. Aetiology of pneumonia can be identified using multiple diagnostic tools including culture, serology and Polymerase Chain Reaction (PCR); common pathogens include Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, some atypical bacteria like Mycoplasma pneumoniae and Chlamydophila pneumoniae. Aim: To find out the bacteriological agents causing Community Acquired Pneumonia (CAP) in under five year children and to compare the conventional culture and PCR in identifying the pathogen. Materials and Methods: This cross-sectional study was undertaken in the Department of Microbiology and Department of Paediatrics in a tertiary care centre of Assam, India, between March 2016 to September 2018. The study was undertaken with 200 under five year old children who were clinically diagnosed as CAP. Oropharyngeal (OP) swabs and blood culture were processed for bacteriological culture. PCR assay of OP swabs for Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus etc., including atypical bacteria like Mycoplasma pneumoniae and Chlamydophila pneumoniae were performed. Data entry, database management and statistical analysis were performed using Epi-Info software version 7.0. Results: A total of 200 subjects were included in the present study with a male:female ratio of 1.63:1. Most of the study subjects were <11 months of age. Most common isolates were Streptococcus pneumoniae (26.5%) and Staphylococcus aureus (25%) from OP swabs; blood culture revealed mostly Staphylococcus aureus (59%) and Streptococcus pneumoniae (25%). PCR assay of OP swabs were found positive mostly for Staphylococcus aureus (47%), Streptococcus pneumoniae (21.5%) while two children were positive for Haemophilus influenzae; Bordetella pertussis was detected in one child. On evaluation, PCR assay in detecting the bacterial pathogen was found statistically more significant than conventional culture of OP swabs (p<0.05). Conclusion: Staphylococcus aureus and Streptococcus pneumoniae were the most common bacterial organisms in the study. PCR assay was found to be more useful in diagnosing the pathogen for bacterial pneumonia including those difficult to grow in conventional culture.

Adenotonsillar Hypertrophy

We sought to investigate the prevalence of potentially pathogenic bacteria in secretions and tonsillar tissues of children with chronic adenotonsillitis hypertrophy compared to controls. Prospective case-control study comparing patients between 2 and 12 years old who underwent adenotonsillectomy due to chronic adenotonsillar hypertrophy to children without disease. We compared detection of Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Pseudomonas aeruginosa, and Moraxella catarrhalis by real-time PCR in palatine tonsils, adenoids, and nasopharyngeal washes obtained from 37 children with and 14 without adenotonsillar hypertrophy. We found high frequency (>50%) of Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis, and Pseudomonas aeruginosa in both groups of patients. Although different sampling sites can be infected with more than one bacterium and some bacteria can be detected in different tissues in the same patient, adenoids, palatine tonsils, and nasopharyngeal washes were not uniformly infected by the same bacteria. Adenoids and palatine tonsils of patients with severe adenotonsillar hypertrophy had higher rates of bacterial coinfection. There was good correlation of detection of Moraxella catarrhalis in different sampling sites in patients with more severe tonsillar hypertrophy, suggesting that Moraxella catarrhalis may be associated with the development of more severe hypertrophy, that inflammatory conditions favor colonization by this agent. Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, and Moraxella catarrhalis are frequently detected in palatine tonsils, adenoids, and nasopharyngeal washes in children. Simultaneous detection of Moraxella catarrhalis in adenoids, palatine tonsils, and nasopharyngeal washes was correlated with more severe tonsillar hypertrophy.

Factores De Riesgo

La neumonía adquirida en la comunidad (NAC) continúa siendo una de las principales causas de mortalidad en Colombia, pues es responsable de 13 de cada 100.000 muertes. Su principal agente etiológico es el Streptococcus pneumoniae, seguido por Haemophilus influenzae y Staphylococcus aureus. Se han identificado algunos factores de riesgo como comorbilidades y factores de exposición epidemiológica, los cuales incrementan la posibilidad de contraer una infección por microrganismos específicos. Su diagnóstico debe basarse tanto en la clínica como en hallazgos paraclínicos e imagenológicos. Herramientas como las escalas CURB-65 y PSI asociadas al criterio clínico permiten calcular el riesgo de mortalidad y el área de atención del paciente según su clasificación. En esta revisión se consideran los diferentes elementos para una adecuada evaluación y manejo del paciente que cursa con NAC, el uso de algunos biomarcadores, situaciones especiales para apreciar, como la neumonía severa, y estrategias para una adecuada prevención.

The bacteremia level as well as the administration of antibiotics before blood collection may significantly affect the recovery of bacterial pathogens from pediatric blood cultures in BacT/Alert Virtuo or Bactec FX BC systems, which remain the common techniques to diagnose bacteremia in pediatric patients. We simulated pediatric blood cultures with low or intermediate bacteremia level to evaluate BacT/Alert PF Plus and Bactec Peds Plus blood culture bottles for resin-based inactivation of 16 antibiotic–bacterium combinations. Overall, 105/192 (54.7%) of BacT/Alert PF Plus bottles and 69/192 (36.0%) of Bactec Peds Plus bottles allowed organisms to grow when exposed to antibiotics. In particular, both BacT/Alert PF Plus and Bactec Peds Plus bottles proved to be effective with piperacillin/tazobactam and Pseudomonas aeruginosa or with oxacillin and methicillin-susceptible Staphylococcus aureus (100% growth), whereas no effectiveness was apparent with ceftriaxone and Escherichia coli, Streptococcus agalactiae, or Streptococcus pneumoniae or with cefepime and E. coli (0% growth). In some relevant instances (e.g., with vancomycin and methicillin-resistant S. aureus or Streptococcus pneumoniae), BacT/Alert PF Plus bottles were superior to Bactec Peds Plus bottles. Together, these findings underscore the potentiality of resin-containing bottles to enhance diagnosis of bacteremia in pediatric patients on antimicrobial therapy. This is particularly true with one of the evaluated BC systems and with simulated intermediate bacteremia level only.

Blistering Skin Disorders

Staphylococcal scalded skin syndrome (SSSS) describes a spectrum of superficial blistering skin disorders caused by the exfoliative toxins of Staphylococcus aureus that originates from a focus of infection that may be a purulent conjunctivitis, otitis media, or occult nasopharyngeal infection. It usually begins with fever, irritability, and a generalized, paint, orange-red, macular erythema with cutaneous tenderness, and the rash progress from scarlatiniform to a blistering eruption in 24 to 48 hours. A diagnosis must distinguish SSSS from other skin diseases, such as toxic epidermal necrolysis, epidermolysis bullosa, bullous erythema multiforme, Streptococcal impetigo or listeriosis and thermal or chemical burns, all of which can manifest with similar symptoms. The prognosis of SSSS in children who are appropriately treated is good, with a mortality of less than 5%. A case was a three moths old boy hospitalized in Pediatric ward M. Djamil hospital with chief complain redness and peeling of the skin since 2 days before hospitalized. Culture of the skin, eyes and nose was Staphylococcus aureus, and patients was given ampicillin and gentamycin for seven days.
