Amplitude-integrated electroencephalography in full-term newborns without severe hypoxic-ischemic encephalopathy: case series.
AIM: To assess the diagnostic value of amplitude-integrated electroencephalography (EEG) in comparison to standard EEG in newborns without severe hypoxic-ischemic encephalopathy who were at risk for seizures. METHODS: The study included a consecutive series of 18 term newborns without severe hypoxic-ischemic encephalopathy, but with clinical signs suspicious of epileptic seizures, history of loss of social contact, disturbance of muscle tone, hyperirritability, and/or jitteriness. Amplitude-integrated and standard EEG tracings were assessed for background pattern, epileptiform activity, and sleep-wake cycling. RESULTS: Amplitude-integrated EEG and standard EEG recordings of 15 newborns were suitable for analysis. Only two different background patterns were seen on amplitude-integrated EEG and standard EEG, with the absence of severely abnormal background patterns. Of 15 newborns, epileptiform discharges were present on amplitude-integrated EEG in 3 newborns, and on standard EEG in 6 newborns. Sensitivity of seizures discharges on amplitude-integrated EEG to correspond with epileptiform discharges on standard EEG was 50%; specificity 100%,positive predictive value 100%, and negative predictive value 75%. Of 4 newborns suspected of having sleep myoclonus, amplitude-integrated EEG correctly identified the newborn who had epileptiform activity on standard EEG. CONCLUSION: The diagnostic value of amplitude-integrated EEG monitoring of term newborns without severe hypoxic-ischemic encephalopathy is limited, but could have a role in evaluating presence or absence of epileptiform activity and in differentiating non-epileptic movement from seizures.

Comparison of two methods of neurologic assessment in infants.
Information provided by the neonatal neurologic assessment is important for identifying infants with neurologic abnormalities at a very early age. The aim of this study was to compare two distinct approaches to the neurologic assessment of newborns: the Amiel-Tison neurologic assessment, and Prechtl's qualitative assessment of general movements. The results of both assessments were studied in a group of 45 preterm infants with different risk factors for brain damage that were compared at term age and at a corrected age of 3 months. The predictive power of the two methods regarding the neurologic and developmental outcome at a corrected age of 12-15 months was analyzed. The agreement of the two methods was excellent at term (kappa = 0.87) and good at 3 months (kappa = 0.54). The sensitivity of both methods for detecting children with neurologic abnormalities was high both at term and at 3 months (0.92, 1.0 for the Amiel-Tison assessment and 0.96, 1.0 for general movements). The specificity of both techniques was low at both ages (0.45, 0.75 for the Amiel-Tison assessment and 0.40, 0.35 for general movements). The agreement of the neurologic and developmental outcome was better with the Amiel-Tison assessment (kappa = 0.39, 0.77) than with the observation of general movements (kappa = 0.38, 0.37).

Amiel-Tison Neurological Assessment at term age: clinical application, correlation with other methods, and outcome at 12 to 15 months.
The aims of this study were: (1) to perform the Amiel-Tison Neurological Assessment (ATNA) in a group of infants with different risk factors for brain damage; (2) to analyze the results of the examinations in light of the risk factors and presumed aetiology; (3) to compare results of examinations with results of cranial ultrasound, electroencephalography (EEG), and cerebral function monitoring (CFM); and (4) to evaluate neurological outcome at 12 to 15 months of age using the Amiel-Tison and Gosselin method, and developmental outcome using the Bayley Scales of Infant Development. Participants were 52 term, newborn infants (31 males, 21 females) with risk factors for brain damage. Mean birthweight was 3288g (SD 661g) and mean gestational age was 39.4wks (SD 1.2wks); range 38 to 41.3wks. Mean age at admission to a neonatal special care unit was 75h, (SD 13.7h). The group with a dynamic (evolving) clinical profile differed significantly from the group with a static (stable) profile in terms of aetiology, while the group with signs of prenatal brain damage differed from the group without these signs regarding aetiology and the level of severity of neurological signs. Sensitivity of the ATNA to detect infants with abnormal ultrasound was 0.97, with EEG 0.89, and with CFM 0.88. At follow-up at 12 to 15 months 47 children were examined: neurological examination was normal in 25 and five children had a minor, five a moderate, and 12 a severe neurological deficit. Agreement of the ATNA with neurological and developmental assessment at follow-up was very good. Our findings suggest that the ATNA is also of value in assessing aetiology and timing of brain lesions.

Congenital hypotonia: is there an algorithm?
This study was performed with the aim of determining the diagnostic profile of newborns with hypotonia and of analyzing the usefulness of different procedures in the diagnostic process. One hundred thirty-eight hypotonic newborns were identified through the search of hospital records in a 10-year period: 121 (88%) had central hypotonia and 13 (9%) had peripheral hypotonia, whereas 4 (3%) remained unclassified. Analysis of the contribution of clinical data and results of investigations led to the construction of an algorithm, by which all cases in the group were diagnosed. Step 1, which included clinical data and results of examinations, solved 50% of all diagnosed cases. Neuroimaging techniques made up step 2 and contributed to the diagnosis in 13%. Step 3 was accomplished by a search through Oxford Medical Databases, which yielded the final diagnosis in 9%, whereas karyotyping and fluorescent in situ hybridization for Prader-Willi syndrome comprised step 4 and contributed to the diagnosis in 6.5%. Biochemical tests formed step 5 and contributed to the diagnosis in 6%. Step 6, which included specific investigations of muscle and nerve, was diagnostic in 6%. The remaining cases (6.5%) were diagnosed only after several follow-up examinations. These results could assist the neonatologist when deciding the diagnostic approach to floppy newborns.
