Gram negative endocarditis is relatively rare in pediatrics but when they occur they are most frequently caused by one of the HACEK (<em>Haemophilus species, Actinobacillus actinomycetemcomitans, C. hominis, Eikenella corrodens</em> and <em>Kingella kingae</em>) group of microorganisms. Within the HACEK group of microorganisms there have been approximately 100 cases of <em>Cardiobacterium hominis</em> endocarditis reported in the literature, but only 2 previous cases of endocarditis and one case of pericarditis have been reported in children. In this report, we present a case of a 12-year-old boy with a right ventricle to pulmonary artery conduit for Tetralogy of Fallot with pulmonary atresia who presented at an annual cardiology examination with a 3 week history of fatigue and was found to have a vegetation on routine echocardiogram. Subsequent blood cultures grew <em>Cardiobacterium hominis</em> and the patient was treated successfully with 6 weeks of appropriate antibiotic therapy. We present this case and a review of the literature of the HACEK group of microorganisms in pediatrics.

AbstractBackground. Infectious endocarditis of the tricuspid valve is rare in non-intravenous drug users and patients without central venous devices. The most frequent causative agents are staphylococci, rarely other bacteria.Methods. We describe a case of a 57-year-old patient without history of drug abuse that was admitted to our hospital because of fever with chills, dry cough, loss of appetite and wasting lasting for a few months. He had a venous ulcer on the right foot and interdigital inflammation on both feet. Eikenella corrodens was isolated from blood cultures. Transthoracic echocardiography showed a large vegetation on the anterior leaflet of tricuspid valve. CT scan oh the thorax showed probable septic emboli. The patient was treated conservatively with prolonged double antibiotic regimen. During the treatment there were no further complications.Conclusions. In our patients a rare form of tricuspid valve endocarditis was confirmed, caused by Eikenella corrodens. The possibility of infectious endocarditis should always be considered in patients with prolonged fever, especially when a possible causative agent is isolated from blood cultures.

Gram Positive Cocci

Gram-positive cocci species, notably Staphylococcus, Streptococcus, and Enterococcus account for 80 to 90% of infective endocarditis cases. HACEK microorganisms (Haemophilus spp., Aggregatibacter actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae) account for approximately 3% of cases and Candida species account for 1-2% of cases. Micrococcus luteus is a rare cause of endocarditis. To our knowledge, only 17 cases of prosthetic valve endocarditis have been described due to M. luteus and a single case of native aortic valve endocarditis has been described. The following case is the only documented case of native mitral valve endocarditis. A review of the literature pertaining to Micrococcus endocarditis was performed to further characterize the entity.

We report two cases of symptomatic cardiac ischemia caused by left coronary artery compression. One was a 16-year-old boy with history of the Ross procedure, aortic root aneurysm, and right ventricle-to-pulmonary artery conduit stenosis. The other was a 32-year-old woman with history of pulmonary atresia with ventricular septal defect repair and a giant right ventricle-to-pulmonary artery conduit aneurysm. In both cases, the left coronary artery was compressed by the previously placed valved autologous pericardial roll right ventricle-to-pulmonary artery conduit. Conduit replacement without direct coronary intervention relieved the coronary ischemia. Early diagnosis and relief of external compression avoided potentially fatal outcomes.

Yersinia pseudotuberculosis is a Gram-negative zoonosis which occasionally infects humans via ingestion of contaminated food and water, and typically causes a self-limiting gastrointestinal tract infection. Patients who are immunocompromised, have haemochromatosis or liver cirrhosis are more likely to develop serious complications such as bacteraemia. We present the case of a 76-year-old man with fever and an acutely tender, swollen right knee. Blood cultures were positive for Y. pseudotuberculosis, and 16s ribosomal PCR analysis of his knee aspirate confirmed septic arthritis. He was treated with intravenous ceftriaxone and made an excellent recovery following knee washout. Interestingly, our patient did not have any of the classic risk factors described in the literature, or history of exposure to the pathogen to explain his diagnosis. To our knowledge, this is only the second confirmed case of Y. pseudotuberculosis bacteraemia with septic arthritis, and the first to involve the knee joint.

Kingella kingae is a Gram-negative coccobacilli and it is a member of the HACEK (Haemophilus species, Aggregatibacte actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and  K. kingae). HACEK organisms are typically oropharyngeal commensals and have long been recognized as a cause of infective endocarditis in children and adults. K. kingae in difficult to be recovered from cultured pharyngeal samples due to its slow growth and the high presence of resident bacterial flora, however, the organism can be better detected using PCR tests. Based on our search in PubMed and other sources, we couldn't discover any study about K. kingae originated from any Arab country. Therefore, we wrote this review to draw the attention of our physicians and clinical microbiologists on the importance of this neglected group of organisms in clinical medicine.   However, this review article aims to cover the most important diseases of K. kingae in the pediatric population.

Blood cultures are positive in approximately only 50 per cent of the patients with nongonococcal bacterial infectious arthritis and about 20 per cent of those with gonococcal arthritis. But the concept that gram-negative bacteria could be involved even in chronic arthritis is well-supported. Gram stains are more definitive in staphylococcal arthritis caused by gram-positive bacteria than in bacterial arthritis due to gram-negative bacteria. In the latter situation where gram-negative bacilli are the problem, Gram stains are helpful for 50% of the patients; they are only helpful for 25% of the patients, however, where gram-negative gonococci are the problem. In arthritis due to gram-positive Staphylococci. Gramstained smears are positive for 75% of the patients.

AbstractReports of incidental pneumomediastinum in infants secondary to inflicted trauma are limited. A retrospective review of infants with pneumomediastinum and history of inflicted trauma was performed. A comprehensive literature review was performed. Three infants presented with pneumomediastinum associated with inflicted trauma. Mean age was 4.6 weeks. All patients underwent diagnostic studies, as well as a standardized evaluation for nonaccidental trauma. All patients with pneumomediastinum were resolved at follow-up. Review of the literature identified other cases with similar presentations with related oropharyngeal injuries. Spontaneous pneumomediastinum in previously healthy infants may be associated with inflicted injuries. Clinicians should be aware of the possibility of an oropharyngeal perforation related to this presentation.

Objective: The study aimed to describe the identity and antimicrobial resistance patterns of the causative agents of bacterial meningitis in children referred to Children’s Medical Center (CMC) Hospital, Tehran, Iran. Methods: This retrospective study was performed at CMC Hospital during a six-year period from 2011 to 2016. The microbiological information of the patients with a diagnosis of bacterial meningitis was collected and the following data were obtained: patients’ age, sex, hospital ward, the results of CSF and blood cultures, and antibiotic susceptibility profiles of isolated organisms. Results: A total of 118 patients with bacterial meningitis were admitted to CMC hospital. Sixty-two percent (n=73) of the patients were male. The median age of the patients was ten months (interquartile range [IQR]: 2 months-2 years) and the majority of them (n=92, 80%) were younger than two years of age. The highest number of patients (n=47, 40%) were admitted to the surgery department. Streptococcus epidermidis was the most frequent isolated bacterium (n=27/127, 21%), followed by Klebsiella pneumoniae (n=20/127, 16%), and Staphylococcus aureus (n=16/127, 12.5%). Blood culture was positive in 28% (n=33/118) of patients. Ampicillin-sulbactam and imipenem were the most effective antibiotics against Gram-negative bacteria isolated from CSF cultures. In the case of Gram-positive organisms, ampicillinsulbactam, vancomycin, and linezolid were the best choices. Imipenem was the most active drug against Gram-negative blood pathogens. Also, ampicillin and vancomycin had the best effect on Gram-positive bacteria isolated from blood cultures. Conclusion: Results of this study provide valuable information about the antibiotic resistance profiles of the etiologic agents of childhood meningitis, which can be used for prescription of more effective empirical therapies.
