Comparing the use of, and considering the need for, lumbar puncture in children with influenza or other respiratory virus infections

Background The clinical presentation of influenza in infancy may be similar to serious bacterial infection and be investigated with invasive procedures like lumbar puncture (LP), despite very limited evidence that influenza occurs concomitantly with bacterial meningitis, perhaps because the diagnosis of influenza is very often not established when the decision to perform LP is being considered. Methods A retrospective medical record review was undertaken in all children presenting to the Children's Hospital at Westmead, Sydney, Australia, in one winter season with laboratory-confirmed influenza or other respiratory virus infections (ORVIs) but excluding respiratory syncytial virus, to compare the use of, and reflect on the need for, the performance of invasive diagnostic procedures, principally LP, but also blood culture, in influenza and non-influenza cases. We also determined the rate of concomitant bacterial meningitis or bacteraemia. Findings Of 294 children, 51% had laboratory-confirmed influenza and 49% had ORVIs such as parainfluenza viruses (34%) and adenoviruses (15%). Of those with influenza, 18% had a LP and 71% had a blood culture performed compared with 6·3% and 55·5% in the ORVI group (for both

The need for multidisciplinarity in specialist training to optimize future patient care

Harmonious interactions between radiation, medical, interventional and surgical oncologists, as well as other members of multidisciplinary teams, are essential for the optimization of patient care in oncology. This multidisciplinary approach is particularly important in the current landscape, in which standard-of-care approaches to cancer treatment are evolving towards highly targeted treatments, precise image guidance and personalized cancer therapy. Herein, we highlight the importance of multidisciplinarity and interdisciplinarity at all levels of clinical oncology training. Potential deficits in the current career development pathways and suggested strategies to broaden clinical training and research are presented, with specific emphasis on the merits of trainee involvement in functional multidisciplinary teams. Finally, the importance of training in multidisciplinary research is discussed, with the expectation that this awareness will yield the most fertile ground for future discoveries. Our key message is for cancer professionals to fulfil their duty in ensuring that trainees appreciate the importance of multidisciplinary research and practice

Mycoplasma pneumoniae infection in a clinical setting.

Background: Mycoplasma pneumoniae infection predominantly affects the respiratory tract, although the other organs may also be involved. Previous studies compared the clinical features of patients with M. pneumonia pneumonia to other pathogens and these studies were predominantly adult case series rather than involving children. The objectives of the present study were to compare the clinical features, laboratory, and radiographic findings in children seropositive for M. pneumoniae infection with children tested for suspected M. pneumoniae infection who were seronegative. Methods: Using a retrospective review of children who had complement fixation test (CFT) performed for suspected M. pneumoniae infection, children were classified as seropositive if the acute phase serum titer was ≥64, or paired samples taken 2–4 weeks apart showed a fourfold or greater rise in serum titer. In contrast, a patient with an antibody titer <64 or with paired sera showing less than a fourfold rise in titer was considered seronegative. Results: One hundred and fifty-one children were included. Seventy-six children had serological evidence of M. pneumoniae infection and the remaining 75 were seronegative. Children with M. pneumoniae infection were more likely to have fever >6 days duration prior to admission, crackles on auscultation, radiographic consolidation and thrombocytosis at presentation. In addition, M. pneumoniae infection was associated with pneumonia whereas seronegative children were more likely to have upper respiratory tract infection or asthma. Conclusions: Certain clinical parameters could assist in gauging the likelihood of M. pneumoniae infection in children, and thus direct whether antibiotic treatment is needed
