Is boosting the immune system in sepsis appropriate?

A relative immunosuppression is observed in patients after sepsis, trauma, burns, or any severe insults. It is currently proposed that selected patients will benefit from treatment aimed at boosting their immune systems. However, the host immune response needs to be considered in context with pathogen-type, timing, and mainly tissue specificity. Indeed, the immune status of leukocytes is not universally decreased and their activated status in tissues contributes to organ failure. Accordingly, any new immune-stimulatory therapeutic intervention should take into consideration potentially deleterious effects in some situations.     

Do parents understand the medical information provided in paediatric emergency departments? A prospective multicenter study

Aim: We evaluated the extent to which parents understood the medical information about hospitalization of their child in an emergency department and looked for characteristics likely to increase the risk of poor comprehension. Methods: Prospective multicenter study in thirteen paediatric emergency departments. The parents and doctors completed questionnaires based on closed‐ended questions with a common core of four items: reasons of hospitalization, diagnosis, treatment and seriousness of child condition. We evaluated concordance between parents and doctor answers for these items by comparing their responses. Results: This study included 380 parents. Percentage of concordance was 55% for the reason of hospitalization, 78% for the diagnosis, 92% for the treatment, 48% for the seriousness of the condition and 19% for all four items. The mean number of concordant items was 2.76 (CI 95%, 2.66–2.86). Parents whose children seemed not in pain and parents who received additional information from the nurse showed significantly slightly higher levels of concordance with doctor’s answers (2.98 vs 2.66, p = 0.006 and 2.89 vs 2.60, p = 0.004, respectively). Conclusion: This study shows that improvements are required in the clarity of the information delivered to the parents. The assistance of nurses and optimal pain management may help to improve communication.     

Neonatal Cardiac Arrest From Left Ventricular Cardiac Hemangioma: A Surprising Presentation

Cardiac hemangioma is rare, even more when leading to a cardiovascular collapse in a seemingly healthy newborn. A 6-day-old neonate had a tamponade caused by a basolateral hemangioma of the left ventricle. Partial surgical resection was performed. A congenital lobular capillary hemangioma was diagnosed upon histologic examination. The patient recovered completely and shows normal development at the 12-month follow-up.     

High Frequency and Diversity of Species C Enteroviruses in Cameroon and Neighboring Countries

Human enteroviruses (HEVs) are endemic worldwide and among the most common viruses infecting humans. Nevertheless, there are very limited data on the circulation and genetic diversity of HEVs in developing countries and sub-Saharan Africa in particular. We investigated the circulation and genetic diversity of HEVs among 436 healthy children in a limited area of the far north region of Cameroon in 2008 and 2009. We also characterized the genetic biodiversity of 146 nonpolio enterovirus (NPEV) isolates obtained throughout the year 2008 from stool specimens of patients with acute flaccid paralysis (AFP) in Cameroon, Chad, and Gabon. We found a high rate of NPEV infections (36.9%) among healthy children in the far north region of Cameroon. Overall, 45 different HEV types were found among healthy children and AFP patients. Interestingly, this study uncovered a high rate of HEVs of species C (HEV-C) among all typed NPEVs: 63.1% (94/149) and 39.5% (49/124) in healthy children and AFP cases, respectively. Besides extensive circulation, the most prevalent HEV-C type, coxsackievirus A-13, featured a tremendous intratypic diversity. Africa-specific HEV lineages were discovered, including HEV-C lineages and the recently reported EV-A71 “genogroup E.” Virtually all pathogenic circulating vaccine-derived polioviruses (cVDPVs) that have been fully characterized were recombinants between oral poliovaccine (OPV) strains and cocirculating HEV-C strains. The extensive circulation of diverse HEV-C types and lineages in countries where OPV is massively used constitutes a major viral factor that could promote the emergence of recombinant cVDPVs in the Central African subregion.     

Is Conservative Management for Gastric Perforation Secondary to Intragastric Balloon Possible? Case Report and Review of Literature

Intragastric balloon (IGB) is one of the available options for the management of morbid obesity. The procedure is generally safe and of moderate efficacy in most of the cases. One of the reported complications of IGB is gastric perforation. The management of this complication is classically surgical. To our knowledge, conservative management for gastric perforation secondary to IGB has not been reported. A 27-year-old female patient presented with sudden abdominal pain in the left upper quadrant, 2 months after having an IGB placed. The provisional diagnosis was gastric perforation. Balloon extraction was performed and a conservative management of the gastric perforation was pursued successfully. We therefore propose that this sort of management might be adopted in carefully selected cases.     

Discitis and sacroiliitis diagnosed 15 years after iatrogenic Mycobacterium xenopi inoculation

A patient was diagnosed with discitis and sacroiliitis due to Mycobacterium xenopi. He had a history of percutaneous nucleotomy performed 15 years earlier (in 1992) at the Clinique du Sport, Paris, France, during an outbreak of nosocomial M. xenopi infection at that institution. In 1997, magnetic resonance imaging performed as part of the routine follow-up program for patients who had surgery at the Clinique du Sport during the outbreak was not interpreted as indicating discitis; this assessment was confirmed by our review of the images. Bone and joint infections due to atypical mycobacteria are rare and can develop very slowly. To our knowledge, this is the first reported case of M. xenopi discitis with secondary extension to the sacroiliac joint in an immunocompetent patient.
