BackgroundCritical pertussis is characterized by severe respiratory failure, important leukocytosis, pulmonary hypertension, septic shock and encephalopathy.AimTo describe the clinical course of critical pertussis, and identify predictors of death at the time of presentation for medical care.MethodologyRetrospective study conducted in children’s hospital Tunisian PICU between 01 January and 31 October 2013. Patients with critical pertussis confirmed by RT-PCR and requiring mechanical ventilation were included. Predictors of death were studied.ResultsA total of 17 patients was studied. Median age was 50 days. Mortality was 23%. Predictors risk of mortality were : high PRISM score (Pediatric Risk of Mortality Score) (p=0,007), shock (p=0,002), tachycardia (p=0,005), seizures (p=0,006), altered mental status (p=0,006), elevated WBC count (p=0,003) and hemodynamic support (p=0022). However, the difference did not reach statistical significance in comorbidity, pneumoniae, high pulmonary hypertension or exchange transfusion. Concomitant viral or bacterial co-infection was not related to poor outcome.ConclusionYoung infants are at high risk to have critical pertussis. Despite advances in life support and the treatment of organ failure in childhood critical illness, critical pertussis remains difficult to treat.
Rabies remains a serious public health problem in many developing countries. The diagnosis is easy when a non-immunised patient presents with hydrophobia and hypersalivation after a bite by a known rabid animal but more difficult when a patient presents atypical symptoms after having received rabies postexposure prophylaxis. Rabies postexposure prophylaxis failure is rare. We report a case of a 6-year-old boy who presented febrile seizure with agitation and cerebellar signs, without hydrophobia or hypersalivation, 17 days after a dog bite. Despite four doses of rabies vaccine and immunoglobulin, he died. Diagnostic confirmation of rabies encephalitis was made in post mortem on brain biopsies by fluorescent antibody technique.
Invasive aspergillosis is a life-threatening condition in patients with chronic granulomatous disease (CGD). Skin invasion by Aspergillus occurs most commonly by contiguity to a neighboring cavity. We describe an unusual case of invasive cutaneous aspergillosis presented as a large burgeoning tumor in a 4-year-old girl with CGD who underwent surgical treatment for bifocal osteomyelitis of the left leg. The skin invasion occurred 4 months after a "successful" treatment of invasive pulmonary aspergillosis. Atypical presentation and diagnostic difficulties are discussed. Invasive cutaneous aspergillosis may be polymorphic. The diagnosis should be considered early in the etiological investigation of any suspicious skin lesions in CGD even in uncommon aspects such as burgeoning tumors.
We report a case of community-acquired meticillin-resistant Staphylococcus aureus (CA-MRSA) preseptal cellulitis complicated by zygomatic osteomyelitis, cavernous sinus thrombosis, meningitis, and necroziting pneumonia in a previously healthy two and half month old girl. This case exemplifies an aggressive and disseminated CA-MRSA infection with deep venous thrombosis in an infant without predisposing risk factors. The literature is reviewed and recommendations for management are provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
