Department of Clinical Services (Dr Ustad), St Olavs Hospital, Trondheim University Hospital, Trondheim, Norway; Department of Laboratory Medicine (Drs Ustad and Evensen), Children's and Women's Health, and Department of Public Health and Nursing (Dr Evensen), Faculty of Medicine and Health Sciences, Norwegian University of Science and Technology, Trondheim, Norway; Department of Physiotherapy (Dr Evensen), Trondheim Municipality, Trondheim, Norway; Institute of Pediatrics and Neonatal Medicine and NICU (Ms Bertoncelli and Drs Frassoldati and Ferrari), Modena University Hospital, Modena, Italy.

Purpose: To examine concurrent and predictive validity of the optimality list "Detailed Assessment of General Movements (GMs) During Preterm and Term Age."

Methods: Video clips of general movements were analyzed for 20 infants born preterm without severe brain lesions. Concurrent validity of the optimality list compared with the General Movement Assessment (GMA) was examined. The General Movement Optimality Scores (GMOSs) between infants with normal and poor repertoire GMA were examined. Estimates of diagnostic accuracy were calculated.

Results: The GMOS correlated with the GMA and differed between infants with normal and poor repertoire GMA. The area under the curve was below 0.53 with respect to normal or abnormal general movements at 3 months' corrected age.

Conclusions: Concurrent validity of the optimality list was moderate to high compared with the GMA, but its predictive validity for general movements at 3 months' corrected age was low.

Systematic review of maternal voice interventions demonstrates increased stability in preterm infants.

Acta Paediatr 2017 Aug 19;106(8):1220-1229. Epub 2017 Apr 19.

Department of Diagnostics, Clinical and Public Health Medicine, University of Modena and Reggio Emilia, Modena, Italy.

We systematically reviewed how effectively maternal voice interventions supported the clinical outcomes and development of preterm infants. A total of 512 preterm infants were included in 15 studies with different designs, from January 2000 to July 2015. Live and recorded maternal voice interventions were associated with the physiologic and behavioural stabilisation of preterm infants, with fewer cardiorespiratory events, but the evidence was insufficient to evaluate the long-term effects. Well-defined determinants and clear setting conditions are needed for such interventions.

Conclusion: Further research that investigates the long-term efficacy and effects of live maternal voices on preterm infant development is needed.

The ontogeny of fidgety movements from 4 to 20weeks post-term age in healthy full-term infants.

Early Hum Dev 2016 12 27;103:219-224. Epub 2016 Oct 27.

Research Unit iDN - Interdisciplinary Developmental Neuroscience, Institute of Physiology, Center for Physiological Medicine, Medical University of Graz, Graz, Austria.

Background: Fidgety movements (FMs) are an early accurate marker for normal development.

Aim: The study assessed the ontogeny of normal FMs from 4 to 20weeks post-term age (PTA).

Study Design: Longitudinal prospective study of healthy full-term infants video recorded every second week from birth to 20weeks PTA.

Subjects: 21 full-term newborns were enrolled.

Outcome Measures: Temporal organization, amplitude, character, predominance in proximal and/or distal parts of the body and the presence of FMs in fingers and wrists were independently scored by three observers.

Results: From 4 to 10weeks PTA, FMs were sporadic, becoming intermittent in 1-2weeks; they occurred in the proximal parts, with larger and jerkier movements in the following period. From 11 to 16weeks PTA FMs became smaller in amplitude and slower in speed, they were present in all body parts and were more continual than before. Rotational movements in wrists and ankles and finger movements with open hands appeared. From 17 to 20weeks PTA, FMs became more discontinuous and disappeared at 18-20weeks PTA.

Conclusions: Developmental course of FMs was seen between 4 and 20weeks PTA with changes in temporal organization, amplitude, speed and body parts involved. The best time for scoring FMs is between 12 and 16weeks PTA.

Hypothermia reduces seizure burden and improves neurological outcome in severe hypoxic-ischemic encephalopathy: an observational study.

Dev Med Child Neurol 2016 Dec 22;58(12):1235-1241. Epub 2016 Jul 22.

Division of Neonatal Intensive Care Unit, Department of Pediatrics, University Hospital, Modena, Italy.

Aim: To evaluate the antiepileptic effect of hypothermia and its association with neurological outcome in infants with moderate and severe hypoxic-ischemic encephalopathy (HIE).

Method: We compared polygraphic electroencephalography monitoring and outcome data in 39 cooled and 33 non-cooled term newborn infants, born between January 2005 and March 2013, and hospitalized because of signs of asphyxia and moderate to severe HIE.

Results: Cooled newborn infants had fewer seizures (14/39 vs 20/33 p=0.036) and status epilepticus (7/39 vs 13/33, p=0.043), a lower mean duration of seizures (18mins vs 133mins, p=0.026), fewer administered antiepileptic drugs (median 0 vs 1, p=0.045), and more commonly a good outcome at 24 months (normal/mild motor impairment in 32/39 vs 16/33, p=0.003). Seizure burden (accumulated duration of seizures over a defined period) in cooled patients with both moderate (0.0 vs 0.1; p=0.045) and severe HIE (0.3 vs 4.9; p=0.018) was lower than in non-cooled patients. Compared with non-cooled patients, a good outcome was more common in cooled newborn infants with severe HIE (p=0.003).

Interpretation: Hypothermia has an antiepileptic effect in both moderate and severe neonatal HIE. The lower seizure burden in cooled newborn infants with severe HIE is more commonly associated with normal outcome at 24 months.

Prognostic value of diffusion-weighted imaging summation scores or apparent diffusion coefficient maps in newborns with hypoxic-ischemic encephalopathy.

Pediatr Radiol 2014 Sep 9;44(9):1141-54. Epub 2014 Apr 9.

Neuroradiology Unit, Department of Neuroscience, Nuovo Ospedale Civile S. Agostino Estense di Modena, Azienda Unità Sanitaria Locale di Modena, via Giardini 1355, Modena, 41100, Italy,

Background: The diagnostic and prognostic assessment of newborn infants with hypoxic-ischemic encephalopathy (HIE) comprises, among other tools, diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps.

Objective: To compare the ability of DWI and ADC maps in newborns with HIE to predict the neurodevelopmental outcome at 2 years of age.

Materials And Methods: Thirty-four term newborns with HIE admitted to the Neonatal Intensive Care Unit of Modena University Hospital from 2004 to 2008 were consecutively enrolled in the study. All newborns received EEG, conventional MRI and DWI within the first week of life. DWI was analyzed by means of summation (S) score and regional ADC measurements. Neurodevelopmental outcome was assessed with a standard 1-4 scale and the Griffiths Mental Developmental Scales - Revised (GMDS-R).

Results: When the outcome was evaluated with a standard 1-4 scale, the DWI S scores showed very high area under the curve (AUC) (0.89) whereas regional ADC measurements in specific subregions had relatively modest predictive value. The lentiform nucleus was the region with the highest AUC (0.78). When GMDS-R were considered, DWI S scores were good to excellent predictors for some GMDS-R subscales. The predictive value of ADC measurements was both region- and subscale-specific. In particular, ADC measurements in some regions (basal ganglia, white matter or rolandic cortex) were excellent predictors for specific GMDS-R with AUCs up to 0.93.

Conclusions: DWI S scores showed the highest prognostic value for the neurological outcome at 2 years of age. Regional ADC measurements in specific subregions proved to be highly prognostic for specific neurodevelopmental outcomes.

Compartment syndrome after viper-bite in toddler: case report and review of literature.

Acta Biomed 2012 Apr;83(1):44-50

Department of Pediatrics, University of Modena & Reggio Emilia, Modena, Italy.

Snakebites in Italy are a rare source of severe medical condition, except in case of venomous snakes. The venom causes both local and/or systemic complication which may determine death in 6-60 hours, particularly in children and the elderly. In fact, the same amount of venom affects children more severely than adults because of the reduced total dilution volume in children. The only specific and conflicting therapy for venomous snakebite is to administer the appropriate anti-venom; the remaining therapy is symptomatic and supportive. We describe the case of a 22-month-old child who, despite appropriate symptomatic treatment, developed severe signs and an acute compartment syndrome of the right upper limb, a rare complication of venom snakebite. Administration of antivenom and fasciotomy were needed to resolve the acute episode permitting a positive outcome. On the basis of literature review and our experience we hypothesize an algorithm for the treatment of these patients.
