Pneumococcal septic shock after neonatal respiratory syncytial virus bronchiolitis: A case report and literature review.

BACKGROUND: Bronchiolitis is a common cause of hospitalisation of infants less than a year old, with most infants recovering without complications. Respiratory syncytial virus (RSV) is a leading cause of bronchiolitis. Antimicrobial stewardship programmes do not recommend antibiotics for viral infections in neonates unless documented evidence of secondary bacterial infection is present. CASE REPORT: We present the case of a 7-day-old infant admitted to hospital with chest retractions and fever. The baby was hospitalised, empirical antibiotic therapy was administered, and non-invasive ventilation was started. When the viral aetiology was identified and clinical conditions improved, antibiotics were discontinued. However, after 48 hours, the newborn's condition worsened because of pneumococcal septic shock. Intravenous fluids, catecholamine support, and wide-spectrum antibiotics were administered. Non-invasive ventilation was re-started and continued until the full recovery. CONCLUSIONS: There is increasing evidence that RSV and S. pneumoniae co-infect and interact with each other, thus increasing respiratory diseases' severity. We provide a brief overview of the main international guidelines for managing bronchiolitis. Guidelines suggest avoidance of antibiotics use when the diagnosis of viral bronchiolitis is confirmed. We discuss the uncertainties regarding antibiotic use, especially in younger infants, who are more exposed to risks of bacterial superinfection.

Severe metabolic alkalosis due to diuretic treatment in a patient with distal renal tubular acidosis: a rare association.

INTRODUCTION: Distal renal tubular acidosis is a rare genetic disease, characterised by deficit in renal tubular transport. Clinical features are metabolic acidosis with hypercloraemia and hypokalemia, and inability in urine acidification. Hypercalciuria may also be present, often treated with the use of a diuretic therapy with thiazides. CASE PRESENTATION: We present a severe disease onset in a neonate with consanguineous parents, both autosomal-recessive for an ATP6VOA4 gene mutation, and a nevertheless severe episode of metabolic alkalosis, occurred in the same patient after few months, during the diuretic therapy. CONCLUSION: Biochemical results lead us to hypothesize a susceptibility to the treatment that need further investigations.

Unusual presentation of Rosai-Dorfman disease in a 14-month-old Italian child: a case report and review of the literature.

BACKGROUND: Rosai-Dorfman disease (RDD) is a rare form of histiocytosis characterized by histiocyte proliferation within lymph nodes and extranodal tissue. Here we report an unusual presentation of RDD in an Italian toddler. Moreover, we reviewed the pediatric case reports published between 2004 and 2014, focusing in particular on medical therapy. CASE PRESENTATION: We report the case of a 14-month-old child who developed a progressive swelling of the right parotid, associated with systemic symptoms and abnormal blood tests. During diagnostic work-up, cervical, intraparotid, and unilateral hilar lymphadenopathies were found. Histopathological and immunohistochemistry studies of a cervical lymph node biopsy established the diagnosis of RDD, with positive PCR for Epstein - Barr virus on the biopsy specimen. Oral steroid therapy was started with progressive reduction in size of all lesions, resolution of systemic symptoms, and normalization of blood tests. CONCLUSION: RDD is generally considered a benign and self-limiting form of histiocytosis, usually associated with favorable prognosis. However, complications are not infrequent and fatal cases were reported even in children. Efforts should be made to establish the best therapeutic strategy for this disease, as no well-defined guidelines exist. Finally, RDD should be included in differential diagnosis of lymphadenopathy and parotid swelling even in very young children.

Preterm birth and developmental problems in infancy and preschool age Part II: cognitive, neuropsychological and behavioural outcomes.

Few studies focus on the neuropsychological and behavioural outcomes of preterm children at preschool age. This article reviews the most recent and relevant contributions on cognitive, neuropsychological and behavioural outcomes, and the neuroradiological findings in extremely and very preterm infants. In the first 2 years of life, cognitive impairment is common: it has an incidence of 30-40% and a higher prevalence than neuromotor and neurosensorial impairments. Recent studies report that even preterm infants with no major disabilities at preschool age perform more poorly than term peers in multiple neuropsychological domains, such as language, attention, memory, visuomotor and visuospatial processing and executive functions. The incidence and severity of problems increase with decreasing gestational age. A delayed acquisition of neuropsychological functions and/or the occurrence of behavioural problems at preschool age are likely to be predictive of the high rate of cognitive deficits at school age and in adolescence. Neuropsychological functions across multiple developmental domains should be assessed longitudinally during routine follow-up checks.

Early predictors of short term neurodevelopmental outcome in asphyxiated cooled infants. A combined brain amplitude integrated electroencephalography and near infrared spectroscopy study.

BACKGROUND: Brain Cooling (BC) represents the elective treatment in asphyxiated newborns. Amplitude Integrated Electroencephalography (aEEG) and Near Infrared Spectroscopy (NIRS) monitoring may help to evaluate changes in cerebral electrical activity and cerebral hemodynamics during hypothermia. OBJECTIVES: To evaluate the prognostic value of aEEG time course and NIRS data in asphyxiated cooled infants. METHODS: Twelve term neonates admitted to our NICU with moderate-severe Hypoxic-Ischemic Encephalopathy (HIE) underwent selective BC. aEEG and NIRS monitoring were started as soon as possible and maintained during the whole hypothermic treatment. Follow-up was scheduled at regular intervals; adverse outcome was defined as death, cerebral palsy (CP) or global quotient <88.7 at Griffiths' Scale. RESULTS: 2/12 Infants died, 2 developed CP, 1 was normal at 6 months of age and then lost at follow-up and 7 showed a normal outcome at least at 1 year of age. The aEEG background pattern at 24 h of life was abnormal in 10 newborns; only 4 of them developed an adverse outcome, whereas the 2 infants with a normal aEEG developed normally. In infants with adverse outcome NIRS showed a higher Tissue Oxygenation Index (TOI) than those with normal outcome (80.0±10.5% vs 66.9±7.0%, p=0.057; 79.7±9.4% vs 67.1±7.9%, p=0.034; 80.2±8.8% vs 71.6±5.9%, p=0.069 at 6, 12 and 24 h of life, respectively). CONCLUSIONS: The aEEG background pattern at 24h of life loses its positive predictive value after BC implementation; TOI could be useful to predict early on infants that may benefit from other innovative therapies.

Preterm birth and developmental problems in the preschool age. Part I: minor motor problems.

Nearly half of very preterm (VP) and extremely preterm (EP) infants suffers from minor disabilities. The paper overviews the literature dealing with motor problems other than cerebral palsy (CP) during infancy and preschool age. The term "minor motor problems" indicates a wide spectrum of motor disorders other than CP; "minor" does not mean "minimal", as a relevant proportion of the preterm infants will develop academic and behavioural problems at school age. Early onset disorders consist of abnormal general movements (GMs), transient dystonia and postural instability; these conditions usually fade during the first months. They were underestimated in the past; recently, qualitative assessment of GMs using Prechtl's method has become a major item of the neurological examination. Late onset disorders include developmental coordination disorder (DCD) and/or minor neurological dysfunction (MND): both terms cover partly overlapping problems. Simple MND (MND-1) and complex MND (MND-2) can be identified and MND-2 gives a higher risk for learning and behavioural disorders. A relationship between the quality of GMs and MND in childhood has been recently described. The Touwen infant neurological examination (TINE) can reliably detect neurological signs of MND even in infancy. However, the prognostic value of these disorders requires further investigations.
