Symptoms and management of cow's milk allergy: perception and evidence.

Introduction: The diagnosis and management of cow's milk allergy (CMA) is a topic of debate and controversy. Our aim was to compare the opinions of expert groups from the Middle East (n = 14) and the European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) (n = 13). Methods: These Expert groups voted on statements that were developed by the ESPGHAN group and published in a recent position paper. The voting outcome was compared. Results: Overall, there was consensus amongst both groups of experts. Experts agreed that symptoms of crying, irritability and colic, as single manifestation, are not suggestive of CMA. They agreed that amino-acid based formula (AAF) should be reserved for severe cases (e.g., malnutrition and anaphylaxis) and that there is insufficient evidence to recommend a step-down approach. There was no unanimous consensus on the statement that a cow's milk based extensively hydrolysed formula (eHF) should be the first choice as a diagnostic elimination diet in mild/moderate cases. Although the statements regarding the role for hydrolysed rice formula as a diagnostic and therapeutic elimination diet were accepted, 3/27 disagreed. The votes regarding soy formula highlight the differences in opinion in the role of soy protein in CMA dietary treatment. Generally, soy-based formula is seldom available in the Middle-East region. All ESPGHAN experts agreed that there is insufficient evidence that the addition of probiotics, prebiotics and synbiotics increase the efficacy of elimination diets regarding CMA symptoms (despite other benefits such as decrease of infections and antibiotic intake), whereas 3/14 of the Middle East group thought there was sufficient evidence. Discussion: Differences in voting are related to geographical, cultural and other conditions, such as cost and availability. This emphasizes the need to develop region-specific guidelines considering social and cultural conditions, and to perform further research in this area.

"Baby-led weaning" - Progress in infant feeding or risky trend?

Baby-led weaning (BLW), proposed as a new form of complementary feeding, has emerged as a real trend phenomenon in the media. Infants are seated at the family table from the age of 6 months, facing the foods they grab and bring to their mouth: they decide which foods they want to eat and what amount. The consumption of mashed foods and the use of a spoon are totally discouraged. BLW is increasingly used in nurseries and centers of young children. A bibliographic search carried out between 2000 and 2021 found 423 articles, of which 38 were selected. The clinical studies selected are 11 cross-sectional observational studies and two randomized controlled studies. BLW promotes breastfeeding, the early introduction of morsels, the respect of the child's appetite, the use of unprocessed foods, and the choice of "homemade" and friendliness. These benefits can nonetheless be reached with usual complementary feeding (SCF), according to current recommendations. Other benefits are claimed without scientific evidence such as easier achievement of dietary complementary feeding and an optimal growth with prevention of excess weight gain. BLW has some obvious downsides. The infant may not get enough energy, iron, zinc, vitamins, and other nutrients, or too much protein, saturated fat, salt, or sugar. The risk of choking, which must be distinguished from the physiological gagging reflex, has not been ruled out by scientific studies. Currently, the Nutrition Committee of the French Pediatric Society considers that the data published to date in terms of benefits and risks of BLW do not lend themselves to advice for this practice in preference over SCF carried out according to current recommendations.

Vitamin D and calcium intakes in general pediatric populations: A French expert consensus paper.

OBJECTIVES: Nutritional vitamin D supplements are often used in general pediatrics. Here, the aim is to address vitamin D supplementation and calcium nutritional intakes in newborns, infants, children, and adolescents to prevent vitamin D deficiency and rickets in general populations. STUDY DESIGN: We formulated clinical questions relating to the following categories: the Patient (or Population) to whom the recommendation will apply; the Intervention being considered; the Comparison (which may be "no action," placebo, or an alternative intervention); and the Outcomes affected by the intervention (PICO). These PICO elements were arranged into the questions to be addressed in the literature searches. Each PICO question then formed the basis for a statement. The population covered consisted of children aged between 0 and 18 years and premature babies hospitalized in neonatology. Two groups were assembled: a core working group and a voting panel from different scientific pediatric committees from the French Society of Pediatrics and national scientific societies. RESULTS: We present here 35 clinical practice points (CPPs) for the use of native vitamin D therapy (ergocalciferol, vitamin D2 and cholecalciferol, vitamin D3) and calcium nutritional intakes in general pediatric populations. CONCLUSION: This consensus document was developed to provide guidance to health care professionals on the use of nutritional vitamin D and dietary modalities to achieve the recommended calcium intakes in general pediatric populations. These CPPs will be revised periodically. Research recommendations to study key vitamin D outcome measures in children are also suggested.

The role of perinatal palliative care following prenatal diagnosis of major, incurable fetal anomalies: a multicentre prospective cohort study.

OBJECTIVE: To describe prenatal decision-making processes and birth plans in pregnancies amenable to planning perinatal palliative care. DESIGN: Multicentre prospective observational study. SETTING: Nine Multidisciplinary Centres for Prenatal Diagnosis of the Paris-Ile-de-France region. POPULATION: All cases of major and incurable fetal anomaly eligible for TOP where limitation of life-sustaining treatments for the neonate was discussed in the prenatal period between 2015 and 2016. METHODS: Cases of congenital defects amenable to perinatal palliative care were prospectively included in each centre. Prenatal diagnosis, decision-making process, type of birth plan, birth characteristics, pregnancy and neonatal outcome were collected prospectively and anonymously. MAIN OUTCOME MEASURE: Final decision reached following discussions in the antenatal period. RESULTS: We identified 736 continuing pregnancies with a diagnosis of a severe fetal condition eligible for TOP. Perinatal palliative care was considered in 102/736 (13.9%) pregnancies (106 infants); discussions were multidisciplinary in 99/106 (93.4%) cases. Prenatal birth plans involved life-sustaining treatment limitation and comfort care in 73/736 (9.9%) of the pregnancies. The main reason for planning palliative care at birth was short-term inevitable death in 39 cases (53.4%). In all, 76/106 (71.7%) infants were born alive, and 18/106 (17%) infants were alive at last follow-up, including four with a perinatal palliative care birth plan. CONCLUSIONS: Only a small proportion of severe and incurable fetal disorders were potentially amenable to limitation of life-sustaining interventions. Perinatal palliative care may not be considered a universal alternative to termination of pregnancy. TWEETABLE ABSTRACT: Perinatal palliative care is planned in 10% of continuing pregnancies with a major and incurable fetal condition eligible for TOP.

The role of nutrition in non-alcoholic fatty liver disease treatment in obese children.

Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease that occurs mostly in the context of insulin resistance and obesity. It has rapidly evolved into the most common cause of liver disease among children. The incidence is high in obese children and a greater risk of disease progression is associated with severe obesity, highlighting the role of nutrition. To date, there is no consensus on NAFLD management. This is a narrative review of clinical studies on the potential benefit of nutritional interventions, including lifestyle modifications, vitamins, docosahexaenoic acid, and probiotics in children with NAFLD. The Comité de nutrition de la Société Française de Pédiatrie (CN-SFP) emphasizes the effect of limiting added sugar intake, i.e., fructose or sucrose-containing beverages, and promoting physical activity in the care of NAFLD.

Impact of different prenatal management strategies in short- and long-term outcomes in monochorionic twin pregnancies with selective intrauterine growth restriction and abnormal flow velocity waveforms in the umbilical artery Doppler: a retrospective observational study of 108 cases.

OBJECTIVES: To review perinatal and neurodevelopmental outcome (NDO) following selective fetoscopic laser coagulation (SFLC), cord coagulation (CC) or expectant management of monochorionic diamniotic twin pregnancies complicated with selective intrauterine growth restriction (sIUGR) and absent or reverse end-diastolic flow (AREDF) in the umbilical arteries (UA). DESIGN AND SETTING: Single-centre retrospective observational study. POPULATION: 108 cases of sIUGR diagnosed before 26+6  weeks' gestation with AREDF in the UA. METHODS: Survival rate and potential risk factors were analysed. NDO was assessed using parental questionnaires. MAIN OUTCOMES MEASURES: Survival, gestational age at delivery and NDO. RESULTS: SFLC, CC and EM were performed in 13, 50 and 45 cases, respectively, with an overall survival of 23.1, 40 and 77.8% and intrauterine demise of the co-twin of 30.8, 10 and 6.7% respectively. Intrauterine demise of the sIUGR twin occurred in 76.9 and 17.8% following SFLC and EM, respectively. The discordance in EFW at diagnosis was higher and absent/negative a-wave in the ductus venosus (DV) was more prevalent in the surgical groups. NDO in survivors at follow up was abnormal in 0 and 18% in the smaller twin following SFLC and EM, respectively, and in 25, 24 and 21% in the larger twin following SFLC, CC and EM, respectively. CONCLUSION: SFLC yielded a poor result. EM seems a valid option when EFW discordance is <30% and a-wave in DV is positive. Otherwise, CC should be considered to protect the AGA co-twin. The long-term outcome of both small and large twins seems unaffected by the choice in primary prenatal management strategy. TWEETABLE ABSTRACT: In type II sIUGR in MC twins, long-term neurodevelopment is normal in over 80% of the survivors.

The challenging management of a series of 43 infants with Netherton syndrome: unexpected complications and novel mutations.

BACKGROUND: Netherton syndrome (NS) is a rare disease caused by SPINK5 mutations, featuring variable skin and hair involvement and, in many cases, allergic manifestations with a risk of lethality, particularly in infants. The clinical management of NS is challenging. OBJECTIVES: To analyse the clinical manifestations of a cohort of infants with NS managed in a reference centre and to draw up recommendations for management. METHODS: We conducted a monocentric analysis of patients with NS. The inclusion criteria were management in our reference centre, a histologically or molecularly confirmed diagnosis of NS and available epidemiological, clinical and laboratory data. RESULTS: A total of 43 patients with NS were included. Hypernatraemia was reported in 23 cases (54%) and associated with a greater likelihood of enteral and/or parenteral nutritional support (P < 0.001). Moreover, hypernatraemia was more frequent in patients with skin manifestations at birth (P = 0.026) and in patients bearing the c.153delT mutation in SPINK5 exon 3 (P = 0.014). The need for enteral and/or parenteral nutritional support was associated with a history of hypernatraemic dehydration (P < 0.001). Several unexpected extracutaneous complications were recorded, and new mutations were reported. The death rate (9% overall) was higher among the subset of patients bearing the c.153delT deletion. CONCLUSIONS: Our data emphasize that neonatal NS is a severe and sometimes lethal multisystem disorder. Patients have a high risk of variable metabolic anomalies (i.e. lethal hypernatraemia) and therefore have major nutritional needs. Cases of NS associated with c.153delT are particularly severe. Unexpected clinical manifestations broadened the phenotypic spectrum of NS. We provide recommendations on the management of the life-threatening manifestations of NS in neonates based on our multidisciplinary experience.

Nutritional risks of ARFID (avoidant restrictive food intake disorders) and related behavior.

Avoidant/restrictive food intake disorder (ARFID) has recently been added to the DSM V (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) as a new class of eating disorders (EDs). ARFID is characterized by a lack of interest in eating or avoiding specific types of foods because of their sensory characteristics. This avoidance results in decreased nutritional intake, eventually causing nutritional deficiencies. In severe cases, ARFID can lead to dependence on oral nutritional supplements, which interferes with psychosocial functioning. The prevalence of ARFID can be as high as 3% in the general population, and it is often associated with gastrointestinal symptoms and mainly appears in children with anxiety disorders. Given the high prevalence of ARFID, a rapid and systematic nutrition survey should be conducted during every pediatric consultation. Its treatment should also be adapted depending on the severity of the nutritional problem and may involve hospitalization with multidisciplinary care (pediatrician, nutritional therapist, dietitian, psychologists, and speech therapists).

Efficacy and safety of hydrolyzed rice-protein formulas for the treatment of cow's milk protein allergy.

Foods for special medical purposes (FSMPs) with a protein fraction made of hydrolyzed rice protein (HRPs) have been on the market in Europe since the 2000s for the treatment of cow's milk protein allergy (CMPA). HRP formulas (HRPFs) are proposed as a plant-based alternative to cow's milk protein-based extensively hydrolyzed formulas (CMP-eHF) beside the soy protein formulas whose use in CMPA is controversial. HRPFs do not contain phytoestrogens and are derived from non-genetically modified rice. HRPFs are strictly plant-based apart from the addition of vitamin D3 (cholecalciferol). As the amino acid content of rice proteins differs from that of human milk proteins, the protein quality of these formulas is improved by supplementation with free lysine, threonine, and tryptophan. The consumption of HRPFs has risen: for example, in France HRPFs account for 4.9% in volume of all formulas for children aged 0-3 years. Several studies have shown the adequacy of HRPFs in treating CMPA. They ensure satisfactory growth from the 1st weeks of life for infants and toddlers, both in healthy children and in those with CMPA. HRPFs can be used to treat children with CMPA either straightaway or in second intention in cases of poor tolerance to CMP-eHF for organoleptic reasons or for lack of efficacy. In France, the cost of HRPFs is close to that of regular infant or follow-on formulas.

Recent actuality about Bacillus cereus and human milk bank: a new sensitive method for microbiological analysis of pasteurized milk.

Three cases of Bacillus cereus infection or colonization occurred in the same region in France, and milk from the milk bank was suspected as a possible common source of contamination. All Batches delivered to the three cases complied with the requirements of the bacteriological reference method recommended by good practices guidelines. Still, a retrospective analysis with a more sensitive method showed one batch to contain B. cereus, however straincomparison revealed no epidemiological link betweenisolates from patients and those from the milk. Consequently, in accordance with the precautionary principle, we developed a new sensitive method for the screening of pasteurized milk for pathogenic bacteria. From January 1 to August 31, 2017, 2526 samples of pasteurized milk were prospectively included in the study. We showed that a 20 mL sample of pasteurized milk incubated for 18 h at 37 °C under aerobic conditions was favoring the detection of B. Cereus. The nonconformity rate was 6.3% for the reference method and 12.6% for the improved method (p < 0.0001). Nonconformity was due to the presence of B. cereus in 88.5% of cases for the improved method and 53% of cases for the reference method (p < 0.0001). Thus our new method is improves the microbiological safety of the product distributed and only moderately increases the rate of bacteriological nonconformity .

Parenteral nutrition for preterm infants: Issues and strategy.

Due to transient gut immaturity, most very preterm infants receive parenteral nutrition (PN) in the first few weeks of life. Yet providing enough protein and energy to sustain optimal growth in such infants remains a challenge. Extrauterine growth restriction is frequently observed in very preterm infants at the time of discharge from hospital, and has been found to be associated with later impaired neurodevelopment. A few recent randomized trials suggest that intensified PN can improve early growth; whether or not such early PN improves long-term neurological outcome is still unclear. Several other questions regarding what is optimal PN for very preterm infants remain unanswered. Amino acid mixtures designed for infants contain large amounts of branched-chain amino acids and taurine, but there is no consensus on the need for some nonessential amino acids such as glutamine, arginine, and cysteine. Whether excess growth in the first few weeks of life, at a time when very preterm infants receive PN, has an imprinting effect, increasing the risk of metabolic or vascular disease at adulthood continues to be debated. Even though uncertainty remains regarding the long-term effect of early PN, it appears reasonable to propose intensified initial PN. The aim of the current position paper is to review the evidence supporting such a strategy with regards to the early phase of nutrition, which is mainly covered by parenteral nutrition. More randomized trials are, however, needed to further support this type of approach and to demonstrate that this strategy improves short- and long-term outcome.

Preterm premature rupture of membranes is a collateral effect of improvement in perinatal outcomes following fetoscopic coagulation of chorionic vessels for twin-twin transfusion syndrome: a retrospective observational study of 1092 cases.

OBJECTIVES: Preterm premature rupture of membranes (PPROM) is a leading complication following fetoscopic laser coagulation (FLC) for twin-twin transfusion syndrome (TTTS). Our primary objective was to describe the impact of improvements in surgical technique on survival and rate of PPROM over time. The secondary objective was to assess potential risk factors for PPROM. DESIGN AND SETTING: Single-centre retrospective observational study. POPULATION: 1092 consecutive cases of TTTS operated by FLC between 2000 and 2016, with a 6.8% rate of loss to follow up. METHODS: The incidence of PPROM and potential risk factors were analysed using competing risks models. MAIN OUTCOME MEASURES: PPROM, neonatal survival and neurological damage at 28 days. RESULTS: PPROM <32 weeks increased from 15 to 40% between 2000 and 2016 along with an overall improvement of perinatal outcomes: dual survival rose from 42 to 66% whereas dual losses dropped two-fold, from 19 to 9%. Gestational age at surgery at <17 weeks was a significant risk-factor for PPROM, with an additional risk of 10% within the first week of surgery. Although early PPROM at <20 weeks carried a 56% risk of miscarriage, the occurrence of PPROM at >20 weeks did not affect survival, despite an increase in preterm birth at <32 weeks. CONCLUSIONS: With significant improvement in perinatal outcomes, possibly related to improvements in surgical technique, postoperative complications have shifted to non-lethal obstetric complications such as PPROM, with rather reassuring postnatal outcomes, despite an increase in preterm birth and, potentially, morbidity. Early surgeries (<17 weeks) are at higher risk of postoperative PPROM. TWEETABLE ABSTRACT: Following laser/TTTS, rates of PPROM increased with perinatal survival; surgeries at <17 weeks are at highest risk.

Fetal brain imaging following laser surgery in twin-to-twin surgery.

OBJECTIVE: To describe the incidence and nature of prenatal brain damage following fetoscopic laser selective coagulation (FLSC) of placental vessels for twin-to-twin transfusion syndrome (TTTS). DESIGN: Retrospective observational study. SETTING: Single center cohort. POPULATION: All consecutive cases referred for TTTS treated by FLSC between 2003 and 2015. METHODS: After the FLSC, patients were followed weekly by ultrasound. Fetal magnetic resonance imaging (MRI) scans were systematically planned at 30-32 weeks of gestation. MAIN OUTCOME MEASURES: Brain damage diagnosed prenatally by ultrasound or MRI. RESULTS: In total, 1023 cases were reviewed. Brain damage was diagnosed prenatally in 22/1023 (2.1%) cases. Diagnosis was performed by ultrasound prior to MRI in 18 (82%) cases. All lesions were within the spectrum of ischaemic haemorrhagic lesions. Postoperative twin anaemia polycythaemia sequence and recurrence of TTTS were significantly associated with brain damage. CONCLUSION: The incidence of prenatal brain damage is low following FSLC, and is strongly associated with incomplete surgery. TWEETABLE ABSTRACT: Following FSLC for TTTS, prenatal brain damage occurs in 2% of cases and is associated with incomplete surgery.

Prenatal factors associated with neonatal survival of infants with congenital chylothorax.

OBJECTIVES: Congenital chylothorax is a rare disease and prognostic factors are key element in properly informing parents. This study aimed at determining the prenatal factors associated with neonatal survival in a cohort of liveborn infants with congenital chylothorax. STUDY DESIGN: Observational monocentric cohort study including all liveborn neonates consecutively admitted for congenital chylothorax. RESULTS: Neonatal mortality was 32% (16/50). Prematurity (or birth weight), persistence of hydrops at birth and the absence of thoracoamniotic shunt procedure were significantly associated with mortality, whereas prenatal diagnosis of pleural effusion, side of pleural effusion, hydrops fetalis and amniodrainage were not. In case of prenatal diagnosis of hydrops fetalis, the reversal in utero of hydrops fetalis was significantly associated with survival (P=0.001). In case of thoracoamniotic shunting, the interval between thoracoamniotic shunting intervention and delivery was significantly longer for patients who survived (P=0.03). CONCLUSIONS: Thoracoamniotic shunting and reversal of hydrops significantly improves survival, whereas prematurity worsened outcome of liveborn infants with congenital chylothorax. Our data also suggest that the interval between thoracoamniotic shunting and birth appears to be crucial; the longer the interval, the more likely is the reversal of antenatal hydrops and neonatal survival.

[Vitamin K in the neonate: Recommendations update]. / Vitamine K chez le nouveau-né : mise à jour des recommandations.

Hemorrhagic disease of the newborn is not common but may be very serious, with cerebral, hepatic, or adrenal gland bleeding. Its prevention is based upon vitamin K1 administration from birth. Scientific studies to validate appropriate treatment policies are scarce, with recommendations coming from expert opinions, retrospective studies, or controversies on possible side effects. After analysis of recent literature data, we propose an oral administration of three doses of 2mg of vitamin K1 at birth, at discharge from the maternity ward, and at 1 month postnatal age for term infants. For premature infants born with a birth weight above 1500g, a weekly dose of 2mg up to term equivalent age may be recommended. For premature infants below 1500g, a weekly dose of 1mg up to 1500g body weight, then a weekly dose of 2mg up to term equivalent age seems appropriate. If oral administration is not possible, the intravenous or intramuscular route may be used with a 50% reduction in dosing.

[Iron requirements during the first 6 months of life]. / Recommandations pour les apports en fer pendant les six premiers mois de vie.

Because of the postnatal redistribution of the iron store, the term infant born after an uneventful pregnancy virtually needs no iron during its first 6 months of life. On the other hand, several factors, such as duration of gestation, gender, mother's iron status, alteration of the iron placental transfer, significantly influence the iron store at birth. Because of their reduced body store at birth and their higher demand during catch-up growth, low birth weight infants should receive an iron supplement, which should be started earlier and given at a higher dose in the more premature infants. This preventive strategy can be given as enteral supplement, preterm formula, or enriched breast milk. Finally, because of its benefits on neonatal morbidity and iron status, delayed umbilical cord clamping is recommended for preterm infants.
