Cryopyrin-associated periodic syndrome: an autoinflammatory disease manifested as neutrophilic urticarial dermatosis with additional perieccrine involvement.

A female newborn presented with a congenital urticarial rash that consisted of fluctuating well-demarcated pink or pale reddish macules or slightly raised papules and plaques. In addition, purulent cerebrospinal fluid was present in the absence of evidence of congenital infection. Skin biopsy revealed a sparse infiltrate throughout the entire dermis, including the eccrine adventitia. The infiltrate was composed mostly of neutrophils, but rarely lymphocytes and eosinophils could also be seen. No vasculitis was present. Because of the presenting attributes, a diagnosis of cryopyrin-associated periodic syndrome (CAPS) was considered and the neonatal-onset multisystem inflammatory disorder (NOMID) that represents the most severe expression of the CAPS clinical spectrum was favored. Diagnosis was confirmed by identification of a mutation in the cold-induced autoinflammatory syndrome-1 gene and by an observed response to treatment with the interleukin-1 receptor antagonist anakinra. Both the clinical and histopathological findings of the presented case may represent a distinct entity within the spectrum of aseptic neutrophilic dermatitis. We refer to this spectrum as neutrophilic urticarial dermatosis (NUD), which may serve as a cutaneous marker of autoinflammation. NUD with perieccrine involvement should prompt consideration of CAPS, especially NOMID, in the context of neonatal multisystem disease.Case ReportsJournal ArticleFLWINSCOPUS: ar.jinfo:eu-repo/semantics/publishe

Torsade de pointe due to QT prolongation following erythromycin administration in a preterm infant.

BACKGROUND: Neonatal sepsis is a major cause of morbidity and mortality in preterm infants. Chorioamnionitis is an important risk factor for the development of sepsis, therefore neonates born to mothers developing signs of amnionitis need to be treated with antibiotics immediately after birth. Ureaplasma spp can be a causative agent of vaginal or intra amniotic infection needing antibiotic treatment. Macrolides are frequently used to treat maternal intrauterine infection, but antibiotic treatment of the neonate should be consciously chosen with consideration of potential side effects. Indeed, macrolides are great purveyors of heart rhythm disorders. CASE PRESENTATION: We describe the case of a 29 weeks preterm infant born to a mother with Ureaplasma spp infection. The baby was treated with erythromycin immediately after birth. During the second day of life, the baby presented some episodes of tachyarrhythmia with premature ventricular beats (PVBs) that were followed by a non-sustained ventricular tachycardia as high as 270 bpm leading to a cardiac arrest. After resuscitation, tachycardia resolved but the rhythm was characterised by numerous PVBs and an electrocardiogram (ECG) diagnosed a Long QT Syndrome (LQTS). Erythromycin was discontinued, and the rhythm normalised a few days after withdrawal. CONCLUSIONS: Erythromycin should be administered in neonates only if no other choice is available, as although generally well tolerated, its administration can be associated with QTc interval prolongation. When no other option is available, paediatricians should be aware to perform cardiac monitoring or at least serial ECGs before and during erythromycin administration

Ictère nucléaire dans un contexte de naissance à domicile

This is the clinical history of a term baby born at home who presents a severe hyperbilirubinémia. The medical monitoring was assessed by a private midwife according to parental choice. On the third day of life, the newborn presented an icterus and was exposed to natural daylight in the familial greenhouse under the midwife recommandations. On that day, no laboratory test precised the bilirubin level. On the fifth day, a blood sampling revealed a very high blood bilirubinémia (31 mg/dl or 527 mmol/L), the baby is refered to our NICU and underwent an exchange transfusion. The radiological assessment report structural abnomalies in basal ganglia seen on both MRI and transfontannellar echography. These lesions are known to be responsible of cerebral palsy and hearing loos. The neurophysiologic investigations showed background abnormaly and depression. The extensive blood sampling excluded haemolysis. The clinical examination brought out neurologic impairement and weight loos in this exclusively breastfed baby. This clinical case point out the increasing risk of home Kernicterius as hospital stays diminish and homebirth enthousiasm rise up. The present clinical situation vouches for an adaptation of care giving to both mother and child at home in order to avoid this severe illness.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

End-of-life decisions and practices for very preterm infants in the Wallonia-Brussels Federation of Belgium

Background: Very preterm birth (24 to < 32 week's gestation) is a major public health issue due to its prevalence, the clinical and ethical questions it raises and the associated costs. It raises two major clinical and ethical dilemma: (i) during the perinatal period, whether or not to actively manage a baby born very prematurely and (ii) during the postnatal period, whether or not to continue a curative treatment plan initiated at birth. The Wallonia-Brussels Federation in Belgium counts 11 neonatal intensive care units. Methods: An inventory of key practices was compiled on the basis of an online questionnaire that was sent to the 65 neonatologists working in these units. The questionnaire investigated care-related decisions and practices during the antenatal, perinatal and postnatal periods, as well as personal opinions on the possibility of standardising and/or legislating for end-of-life decisions and practices. The participation rate was 89% (n = 58). Results: The results show a high level of homogeneity pointing to overall agreement on the main principles governing curative practice and the gestational age that can be actively managed given the current state of knowledge. There was, however, greater diversity regarding principles governing the transition to end-of-life care, as well as opinions about the need for a common protocol or law to govern such practices. Conclusion: Our results reflect the uncertainty inherent in the complex and diverse situations that are encountered in this extreme area of clinical practice, and call for qualitative research and expert debates to further document and make recommendations for best practices regarding several "gray zones" of end-of-life care in neonatology, so that high quality palliative care may be granted to all neonates concerned with end-of-life decisions.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
