Congenital hydrocephalus--prevalence, prenatal diagnosis and outcome of pregnancy in four European regions.

OBJECTIVE: To describe prevalence, prenatal diagnosis and outcome for fetuses and infants with congenital hydrocephalus. METHODS: Data were taken from four European registries of congenital malformations (EUROCAT). The registries included are based on multiple sources of information and include information about livebirths, fetal deaths with GA > or = 20 weeks and terminations of pregnancy for fetal anomaly (TOPFA). All cases from the four registries diagnosed with congenital hydrocephalus and born in the period 1996-2003 were included in the study. Cases with hydrocephalus associated with neural tube defects were not included in the study. RESULTS: Eighty-seven cases with congenital hydrocephalus were identified during the study period giving an overall prevalence of 4.65 per 10,000 births. There were 41 livebirths (47%), four fetal deaths (5%) and 42 TOPFA (48%). Nine percent of all cases were from a multiple pregnancy. Additional non-cerebral major malformations were diagnosed in 38 cases (44%) and karyotype anomalies in eight cases (9%). Median GA at TOPFA was 21 weeks. Among livebirths 61% were diagnosed prenatally at a median GA of 31 weeks (range 17-40 weeks) and median GA at birth was 37 weeks. Fourteen liveborn infants (34%) died within the first year of life with the majority of deaths during the first week after birth. CONCLUSION: Congenital hydrocephalus is a severe congenital malformation often associated with other congenital anomalies. CH is often diagnosed prenatally, although sometimes late in pregnancy. A high proportion of affected pregnancies result in termination for severe fetal anomaly and there is a high mortality in livebirths.

Malaise du nourrisson pensez à une intoxication à l'anis étoil [Apparent life-threatening event in infants: think about star anise intoxication!].

In previous years, several publications have reported cases of infants presenting neurological and gastrointestinal symptoms after ingestion of star anise tea. Such teas are sometimes given in various cultures for the treatment of infant colic pains. In most cases, the cause of intoxication was contamination of Chinese star anise (Illicium verum) by Japanese star anise (Illicium anisatum). Indeed, the toxicity of Illicium anisatum, also known as Shikimi, is caused by its content in potent neurotoxins (anisatin, neoanisatin, and pseudoanisatin), due to their activity as non-competitive antagonists of GABA receptors. The main reasons explaining the frequent contaminations are the strong macroscopic resemblance of the 2 substances, as well as the fact that the fruits are often sold partially broken or in ground form. Therefore, in most cases, chemical analysis is required to determine the possible adulterations. CASE REPORT: A 2-month-old infant, in good general health, was brought to the emergency unit after 3 consecutive episodes of central cyanosis and tetany of the limbs with spontaneous recovery the same afternoon. The child was also very irritable, regurgitated a lot, and positioned himself in opisthotonos. Between these episodes, the neurological exam showed some perturbations (horizontal nystagmus and Bell's phenomenon, hypertony of the extensor muscles, and mild hypotony of the axial flexor muscles) with slow improvement over the following hours. The remaining clinical exam, the laboratory work (complete blood count, renal, hepatic, and muscular tests, capillary blood gas, plasmatic amino acids, and urinary organic acids), and the electroencephalogram findings were all normal. In the course of a detailed interview, the parents reported having given 3 bottles to their child, each one containing 200 mL of an infusion with 4 to 5 fruits of star anise, in the hours preceding the symptoms to relieve colic pains. The last seizure-like event took place approximately 8h after the last ingestion. We could prove the ingestion of anisatin, the toxic substance found in Japanese star anise, and the contamination of Chinese star anise by the Japanese species. Indeed, the anisatin analysis by liquid chromatography and mass spectroscopy (LC-MS) in a urine sample taken 22 h after the last infusion ingestion showed trace amounts of the substance. In another urine sample taken 33 h after ingestion, no anisatin could be detected. Furthermore, the analysis of the fruit sample gave an anisatin concentration of 7800 μg/kg while the maximum tolerance value in Switzerland is 1000 μg/kg. CONCLUSION: The evaluation of ALTE in infants should always include the possibility of intoxication. Star anise is generally considered a harmless medicine. Nevertheless, it can sometimes cause a severe intoxication resulting in various neurological and gastrointestinal symptoms. To prevent such events, not only the parents, but also the care personnel and pharmacists must be informed about the possible adverse effects caused either by the overdose of Chinese star anise or by the eventual contamination of herbal teas with Japanese star anise. A better control of the substances by the health authorities is also necessary.

Jugant a definir ciència : una eina per treballar amb infants, llenguatge i coneixement especialitzat de manera integrada

Treball desenvolupat en el marc del projecte "La construcció del coneixement científic: primeres representacions" de l'IULA de la Universitat Pompeu Fabra (Estopà, 2008), l'objectiu principal del qual és desenvolupar una eina que ajudi a mestres i educadors a l'hora de treballar les dues branques fonamentals del coneixement, les ciències i les lletres, de manera simultània, sense oblidar-ne una per afavorir l'altra. Es tracta d'una eina que, des de la lexicologia i la terminologia, a través del joc, ajudi a conceptualitzar correctament termes de ciència, els dessacralitzi i atregui els infants al coneixement científic.

Neonatal and adult ICU ventilators to provide ventilation in neonates, infants, and children: a bench model study.

BACKGROUND: Using a bench test model, we investigated the hypothesis that neonatal and/or adult ventilators equipped with neonatal/pediatric modes currently do not reliably administer pressure support (PS) in neonatal or pediatric patient groups in either the absence or presence of air leaks. METHODS: PS was evaluated in 4 neonatal and 6 adult ventilators using a bench model to evaluate triggering, pressurization, and cycling in both the absence and presence of leaks. Delivered tidal volumes were also assessed. Three patients were simulated: a preterm infant (resistance 100 cm H2O/L/s, compliance 2 mL/cm H2O, inspiratory time of the patient [TI] 400 ms, inspiratory effort 1 and 2 cm H2O), a full-term infant (resistance 50 cm H2O/L/s, compliance 5 mL/cm H2O, TI 500 ms, inspiratory effort 2 and 4 cm H2O), and a child (resistance 30 cm H2O/L/s, compliance 10 mL/cm H2O, TI 600 ms, inspiratory effort 5 and 10 cm H2O). Two PS levels were tested (10 and 15 cm H2O) with and without leaks and with and without the leak compensation algorithm activated. RESULTS: Without leaks, only 2 neonatal ventilators and one adult ventilator had trigger delays under a given predefined acceptable limit (1/8 TI). Pressurization showed high variability between ventilators. Most ventilators showed TI in excess high enough to seriously impair patient-ventilator synchronization (> 50% of the TI of the subject). In some ventilators, leaks led to autotriggering and impairment of ventilation performance, but the influence of leaks was generally lower in neonatal ventilators. When a noninvasive ventilation algorithm was available, this was partially corrected. In general, tidal volume was calculated too low by the ventilators in the presence of leaks; the noninvasive ventilation algorithm was able to correct this difference in only 2 adult ventilators. CONCLUSIONS: No ventilator performed equally well under all tested conditions for all explored parameters. However, neonatal ventilators tended to perform better in the presence of leaks. These findings emphasize the need to improve algorithms for assisted ventilation modes to better deal with situations of high airway resistance, low pulmonary compliance, and the presence of leaks.

Multiple courses of antenatal corticosteroids for preterm birth (MACS): a randomised controlled trial.

BACKGROUND: One course of antenatal corticosteroids reduces the risk of respiratory distress syndrome and neonatal death. Weekly doses given to women who remain undelivered after a single course may have benefits (less respiratory morbidity) or cause harm (reduced growth in utero). We aimed to find out whether multiple courses of antenatal corticosteroids would reduce neonatal morbidity and mortality without adversely affecting fetal growth. METHODS: 1858 women at 25-32 weeks' gestation who remained undelivered 14-21 days after an initial course of antenatal corticosteroids and continued to be at high risk of preterm birth were randomly assigned to multiple courses of antenatal corticosteroids (n=937) or placebo (n=921), every 14 days until week 33 or delivery, whichever came first. The primary outcome was a composite of perinatal or neonatal mortality, severe respiratory distress syndrome, intraventricular haemorrhage (grade III or IV), periventricular leucomalacia, bronchopulmonary dysplasia, or necrotising enterocolitis. Analysis was by intention to treat. All patients and caregivers were unaware of the treatment given. This trial is registered as number ISRCTN2654148. FINDINGS: Infants exposed to multiple courses of antenatal corticosteroids had similar morbidity and mortality to those exposed to placebo (150 [12.9%] vs 143 [12.5%]). Those receiving multiple doses of corticosteroids also weighed less at birth than those exposed to placebo (2216 g vs 2330 g, p=0.0026), were shorter (44.5 cm vs 45.4 cm, p<0.001), and had a smaller head circumference (31.1 cm vs 31.7 cm, p<0.001). INTERPRETATION: Multiple courses of antenatal corticosteroids, every 14 days, do not improve preterm-birth outcomes, and are associated with a decreased weight, length, and head circumference at birth. Therefore, this treatment schedule is not recommended. FUNDING: Canadian Institutes of Health Research.

Codeine and breastfeeding: cases and STIS position

Codeine is commonly used in North America in the postpartum period for pain associated with episotomyand caesarean section. Analgesic properties of codeine are mainly due to its metabolisation intomorphine (5-10%) via CYP2D6. This enzyme is subject to genetic variability, which can alter theamount of active narcotic excreted into breastmilk. A recent case report highlighted this issue, reportingfatal consequences in a newborn whose mother was taking codeine for episiotomy-related pain (1-2). New-born's blood (post-mortem) and mother's milk showed high morphine concentrations. Genotypeanalysis classified the mother as a CYP2D6 ultrarapid metabolizer, a genotype associated withenhanced formation of morphine from codeine. The authors concluded "clinical and laboratory picturewas consistent with opioid toxicity leading to neonatal death". Subsequent comments expressed reasonnabledoubts on this conclusion, though (3-4). Since, anxiety increased about the safety of codeineduring breastfeeding and genetic screening was proposed as a prevention strategy.STIS position:? Codeine with paracetamol is not a usual pain prescription in the postpartum period in Switzerland.This markedly reduces codeine use during lactation in our country, and may partly explain why webarely collected 3 codeine exposures through breastmilk in 15 years at the STIS (all reported afterabove case's publication and without side effects).? Other centrally acting analgesics are not considered safer (5) than codeine during lactation andrequire close observation for somnolence in both the mother and the infant in case of repeated maternaldosage. A lack of monitoring was salient in the case reported above (1).? If the incidence of CYP2D6 polymorphism (1-10% of individuals in Western Europe) (6) can beconsidered of clinical significance, it is not the exclusive predisposing factor to toxic effects. Healthynewborns can be particularly sensitive to even usual doses of narcotic analgesics because of immaturedrug disposition (7). Conditions leading to impaired clearance or increased susceptibility inthe infant (e.g. preterm birth, metabolic diseases) represent further risk factors for opioid toxicity,regardless of the molecule.In conclusion, when prescribed on a large scale, codein can be rarely associated with adverse drugreactions in breastfed infants (8-9). However, other central acting analgesics cannot be considered asinvariably safer. Therefore, paracetamol and well documented NSAID should be used in 1st choiceduring lactation. In case of severe pain, codeine (with paracetamol) remains an acceptable choice butrequires close monitoring, and breastfeeding mothers should be educated regarding risks related toaccumulation in the newborn. Finally, it is doubtful whether CYP2D6 genetic screening would preventall toxic effects, as other risk factors exist for opioids toxicity

IgG and IgM western blot assay for diagnosis of congenital toxoplasmosis

The aim of this study was to evaluate the utility of western blot (WB) analysis as a diagnostic tool for congenital toxoplasmosis in 215 newborn infants. The children were submitted to clinical examinations to assess macular, neurological and hearing signals. The WB results obtained were compared to the persistence of IgG antibodies at the end of 12 months, which is regarded as the "gold standard" diagnosis of congenital toxoplasmosis. Association between the WB results and the clinical signs presented by the infants was also assessed. Of the 215 children, 177 had a confirmed congenital toxoplasmosis diagnosis and 38 were uninfected. IgG-WB showed a sensitivity of 73.5% and a specificity of 97.4%. IgM-WB showed a sensitivity of 54.8% and a specificity of 94.7%. The IgG-WB and IgM-WB combination increased the sensitivity to 86.5%. The IgM-WB-positive children had a 1.4-fold greater risk of presenting active macular lesions than did those that were IgM-WB-negative. This study showed that the WB assay is a useful tool to confirm a diagnosis of congenital toxoplasmosis and that the IgM-WB-positive results can indicate active macular lesions in newborn infants.

Presence of maternal anti-HBs antibodies does not influence hepatitis B vaccine response in Brazilian neonates

Recently, it was suggested that maternal hepatitis B surface antigen antibodies (anti-HBs) acquired transplacentally could play a negative role in newborn infants' immune response to the hepatitis B vaccine. We compared the hepatitis B virus (HBV) vaccine response in infants born to mothers previously vaccinated against HBV (n = 91) to infants born to mothers who were not previously vaccinated (n = 221). All newborn infants received three intramuscular doses (10 μg) of HBV vaccine (Butang®) at 0,1 and six months. The first dose was administered at the maternity hospital within 12 h of birth. The geometric mean titres of anti-HBs were not different among newborn infants born to mothers who were anti-HBs-negative (492.7 mIU/mL) and anti-HBs-positive (578.7 mIU/mL) (p = 0.38). Eight infants did not respond to the HBV vaccine. Of them, six were born to anti-HBs-negative mothers and two were born to mothers with anti-HBs titres less than 50 mlU/mL. Despite the mother's anti-HBs-positive status, our data show a good immunogenicity of the Brazilian HBV recombinant vaccine in neonates.

Intrapericardial pacemaker in a 2-kilogram newborn.

A 2-kilogram child had a pacemaker implanted by a subxyphoid approach with the generator located under the rectus sheath. Days later, the battery eroded the abdominal wall and the peritoneum. The whole system was removed and a new one was implanted inside the pericardium on an emergent basis.

La protecció dels infants i els adolescents en els mitjans de comunicació: el menor d’edat com a espectador i com a protagonista

El present treball d’investigació es divideix en dos parts. La primera part està dedicada al menor d’edat com a protagonista dels mitjans de comunicació. El menor haurà de consentir els contractes sobre la seva imatge que el vinculin a la realització d’una prestació personal quan tingui prou maduresa tot i que també hi hauran d’intervenir els seus representants legals per tal de complementar la seva capacitat d’obrar i vetllar per a que el contracte respecti la normativa laboral i civil de protecció del menor i en general no sigui perjudicial per aquest. Quan el menor no tingui prou maduresa per a consentir l’ús de la seva imatge o la realització de la prestació personal, els seus representants podran consentir, amb certs requisits, la intromissió en la seva imatge perquè així ho permet excepcionalment la llei orgànica 1/1982. Tanmateix, s’han de preveure determinades solucions per tal que no es produeixi un perjudici injust. La segona part enfoca la protecció del menor des de la seva posició com a espectador. El treball té per objecte l'estudi de les mesures de protecció del menor que preveu el nostre ordenament en l'àmbit mediàtic, tenint en compte la influència que els mitjans de comunicació exerceixen en el desenvolupament de la seva personalitat i en el seu comportament. Una de les tasques més importants que han d'exercir els mitjans en la nostra societat rau en l'educació del menor. En aquesta tasca és primordial la funció dels poders públics. Per això, es du a terme en primer lloc, una anàlisi exhaustiva dels límits o controls existents en el nostre sistema, de l'activitat mediàtica. Un cop detectats els problemes i les deficiències que pateix la nostra legislació en l'àmbit mediàtic, s'exposen a continuació, els motius que determinen la necessitat d'una revisió urgent de la mateixa. Per finalitzar amb les propostes de solució que a criteri de les autores, contribuirien a una millora dels mecanismes de protecció del menor en aquest àmbit.

Oesophageal atresia: prevalence, prenatal diagnosis and associated anomalies in 23 European regions.

OBJECTIVE: To describe prevalence, prenatal diagnosis and epidemiological data on oesophageal atresia from 23 well-defined European regions and compare the prevalence between these regions. DESIGN: Population-based study using data from a large European database for surveillance of congenital anomalies (EUROCAT) for two decades (1987-2006). SETTINGS: Twenty-three participating registries based on multiple sources of information including information about live births, fetal deaths with gestational age ≥20 weeks and terminations of pregnancy. PATIENTS: 1222 cases of oesophageal atresia in a population of 5 019 804 births. RESULTS: The overall prevalence was 2.43 cases per 10 000 births (95% CI 2.30 to 2.57). There were regional differences in prevalence ranging from 1.27 to 4.55. Prenatal detection rates varied by registry from >50% of cases to <10% of cases. A total of 546 cases (44.7%) had an isolated oesophageal anomaly, 386 (31.6%) were multiple malformed and 290 (23.7%) had an association or a syndrome. There were 1084 live born cases (88.7%), 43 cases were fetal deaths and 95 cases were terminations of pregnancy. One-week survival for live births was 86.9% and 99.2% if the gestational age was ≥38 weeks and isolated oesophageal atresia was present. Males accounted for 57.3% of all cases and 38.5% of live born cases were born with gestational age <37 weeks. CONCLUSION: There were regional differences in prevalence of oesophageal atresia in Europe. Half of all cases had associated anomalies. Prenatal detection rate increased from 26% to 36.5% over the two decades. Survival in infants with isolated oesophageal atresia born at term is high.

Severe hypertension and massive proteinuria in a newborn with renal artery stenosis.

Renal vein thrombosis and the congenital nephrotic syndrome have been associated with nephrotic-range proteinuria/nephrotic syndrome and hypertension in the newborn period. We describe a newborn with severe hypertension and proteinuria secondary to unilateral renal artery stenosis. Proteinuria completely disappeared with blood pressure control (with sodium nitroprusside and an angiotensin-converting enzyme inhibitor). Although renin was not measured, we speculate that proteinuria might have been induced by a high renin state, and was controlled by the angiotensin-converting enzyme inhibitor.
