[Neurologic outcome in infants surgically treated for congenital cardiopathy: preliminary data]. / Outcome neurologico di lattanti operati per cardiopatia congenita: dati preliminari.

INTRODUCTION: Both surgical techniques for correction of congenital heart diseases (CHD) and intraoperatory neurologic protection improved during the last 20 years. Nevertheless cardiac surgery is still a risk for neurologic morbidity. METHODS AND PATIENTS: Analysis of the postoperative neurologic status of infants younger than 6 months who underwent cardiac surgery from January 1998 to December 1999. We reviewed the EEG tracings, cranial ultrasound reports (CUS) and CT scans of 48 patients. Diagnoses were: ventricular septal defect = 15, Fallot (TOF) = 9, patent ductus arteriosus (PDA) = 5, coarctation of aorta = 4, atrio-ventricular septal defect = 4, transposition of great arteries (TGA) = 3, hypoplastic left heart syndrome = 2, pulmonary atresia = 2, total anomalous pulmonary veins drainage = 2, double outlet right ventricle = 1, cor triatriatum = 1. Mean age (range) at intervention was 54 days (2-150), 44 infants (91.7%) survived at follow-up: 23 EEG, 22 CUS and 2 CT were performed in the recent postoperative. Among survivors 5/44 had neurologic complications. EEG was altered in 4: two of them (1 TOF, 1 TGA) had pathologic CUS and CT as well (ischemic pattern in the former, atrophy in the latter). Finally a preterm newborn with PDA had mild abnormalities at CUS. After a mean follow-up of 16 +/- 6 months 3/5 patients had mild-to-moderate psychomotor delay and 2 recovered. CONCLUSIONS: According to our preliminary data the prevalence of neurologic complications in infants who undergo cardiac surgery seems to be low. The pathological findings of the recent postoperative seem to recover up to normalization in some cases at mid-term follow-up. As expected, permanent complications effect more often complex CHD. Further follow-up studies to school age will be mandatory to check the very final results of cardiac surgery performed during early infancy.

[A neonatal case of congenital myotonic dystrophy]. / Su un caso neonatale di distrofia miotonica congenita.

Congenital myotonic dystrophy is a rare autosomal disease, caused by an increased number of cytosine-thymine-guanine (CTG) trinucleotide on chromosome 19q. In the neonatal period the most peculiar clinical features are arthrogryposis, hypotonia, facial diplegia, respiratory and feeding difficulties. Clinical and electrical myotonic discharges are difficult to elicit in the newborn. We report a case of congenital myotonic dystrophy in a female newly born presenting with hypotonia, diaphragmatic paralysis, facial diplegia, and contractures of hips, knees and ankles. The diagnosis was confirmed by genetical study on lymphocyte DNA.

The influence of maternal passive and light active smoking on intrauterine growth and body composition of the newborn.

OBJECTIVE: To assess the influence of passive and light active smoking on the reduction of intrauterine growth of the foetus and on modifications in the body composition of the newborn. DESIGN: Random. SETTING: Full term newborn infants at the Department of the Pediatric and Gynaecological Divisions of the City Major Hospital, Chair of Paediatrics, Verona University. SUBJECTS: One hundred and twelve mothers selected after having completed a questionnaire on smoking habits during pregnancy. One hundred and twelve newborn infants were divided into three groups: Group 1: non-smoking and non-exposed mothers; Group 2: non-smoking but exposed mothers; Group 3: light smoking mothers (under 10 cigarettes/d, whether or not also exposed to passive smoking). Examination within 24 h of birth established the anthropometric measurements and estimates of body composition through indices or equations. RESULTS: Newborns of groups 2 and 3 had a statistically significant reduction of fat mass and most anthropometric measurements: fat mass according to Dauncey (P < 0.001), birth-weight (P < 0.013), crownheel length (P < 0.000), upper- and lower-arm length (P < 0.000) and circumference (P < 0.002), triceps skinfold and sum of all skinfolds (P < 0.004). Student t-test, between groups 2 and 3, did not evidence intergroup differences. CONCLUSIONS: Exposure of the foetus to passive and/or light active smoking involves a reduction of most auxiological parameters and not only weight. As regards body composition, smoking appears to reduce fat mass. The prevention of smoking during pregnancy is therefore extremely important, as intrauterine growth seems to be negatively influenced not only by active smoking, but also by passive and light active smoking.

[Criteria for the evaluation of neonatal pain]. / Criteri di valutazione del dolore nel neonato.

The common opinion about the painful sensation in newborn and in premature baby, is that the experience of pain begins since birth. One of the difficulties in taking care of pain in neonatology is the valuation of the symptom: actually there aren't enough sensitive and standard methods to define and quantify the pain of newborns and prematures babies. The authors illustrate two scales of pain valuation, that have been tested and then adopted by different french groups. These scales allow to examine respectively, the healthy newborn and the newborn after surgical care and permit also an objective measure of newborn malaise sensation. These scores need the valuation of clinical signs and physiological parameters that are sometimes neglected during the execution of invasive techniques; therefore these tables would awaken the sanitary staff to newborn expressions of pain or discomfort, allowing a best comprehension of baby's feelings and facilitating in this nursing and pharmacological interventions to relieve pain.
