Whole Goat Milk-Based Formula versus Whey-Based Cow Milk Formula: What Formula Do Infants Enjoy More?-A Feasibility, Double-Blind, Randomized Controlled Trial.

(1) Background: While goat milk formula (GMF) is an alternative to cow milk formula (CMF), infants' preferences for one over the other have not been formally assessed. Specifically, our aim in this study was to determine whether infants experience fewer feeding behavior problems with whole milk-based GMF than with conventional whey-based CMF. (2) Methods: This was a multicenter, double-blind, randomized controlled trial with two-arm parallel assignment conducted in six pediatricians' offices in or near Paris, France, between June 2018 and 31 December 2021. Overall, 64 healthy infants (≤4 months old), predominantly formula-fed, were randomly assigned to either the whole milk-based GMF (n = 33) or whey-based CMF (n = 31) arm. Parents completed the Baby Eating Behavior Questionnaire (BEBQ) and the modified QUALIN questionnaire to evaluate infant feeding behavior and quality of life (psychomotor and socioemotional development), respectively, at inclusion (1 to 5 days before milk delivery) and the final visit (day 28 ± 3 after milk delivery). Informed consent was obtained for all recruited patients, and an ethical committee approved the study. (3) Results: Changes in BEBQ Enjoyment of Food and Slowness in Eating subscale scores from inclusion to final visit did not differ between arms. However, there were significant improvements in subscale scores for Food Responsiveness (GMF: 0.15 ± 1; CMF: -0.48 ± 0.81; p = 0.010) and General Appetite (GMF: 0.26 ± 1.2; CMF: -0.48 ± 0.88; p = 0.012), and modified QUALIN (GMF: 4.6 ± 9.4; CMF: -0.40 ± 7.6; p = 0.03) scores in favor of the GMF group. (4) Conclusions: In this double-blind, randomized controlled trial, GMF-fed infants exhibited a greater general appetite than CMF-fed infants, possibly due to differences in the composition of these formulas (i.e., protein and lipid profiles). In addition, GMF-fed infants enjoyed a better quality of life. There was no difference in food enjoyment between groups. These findings suggest that whole-milk-based GMF could be an attractive alternative to whey-based CMF. Clinical trial registration: NCT03488758 (clinicaltrials.gov).

Association between SARS-CoV-2 infection and Kawasaki-like multisystem inflammatory syndrome: a retrospective matched case-control study, Paris, France, April to May 2020.

We assessed the association between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and Kawasaki disease (KD)-like multisystem inflammatory syndrome in a retrospective case-control study in France. RT-PCR and serological tests revealed SARS-CoV-2 infection in 17/23 cases vs 11/102 controls (matched odds ratio: 26.4; 95% confidence interval: 6.0-116.9), indicating strong association between SARS-CoV-2 infection and KD-like illness. Clinicians should keep a high level of suspicion for KD-like illness during the COVID-19 pandemic.

Assessment of SARS-CoV-2 infection by Reverse transcription-PCR and serology in the Paris area: a cross-sectional study.

BACKGROUND: Several studies indicated that children seem to be less frequently infected with SARS-CoV-2 and are potentially less contagious than adults. To examine the spread of SARS-CoV-2, we combined both Reverse transcription-PCR testing and serology in children in the most affected region in France, Paris, during the COVID-19 epidemic. METHODS: From 14 April 2020 to 12 May 2020, we conducted a cross-sectional, prospective, multicentre study. Healthy controls and pauci-symptomatic children from birth to age 15 years were enrolled by 27 ambulatory paediatricians. A nasopharyngeal swab was taken for detection of SARS-CoV-2 by Reverse transcription-PCR and a microsample of blood for micromethod serology. RESULTS: Among the 605 children, 322 (53.2%) were asymptomatic and 283 (46.8%) were symptomatic. Reverse transcription-PCR and serology results were positive for 11 (1.8%) and 65 (10.7%) children, respectively, with no significant difference between asymptomatic and pauci-symptomatic children. Only three children were Reverse transcription-PCR-positive without any antibody response detected. The frequency of Reverse transcription-PCR SARS-CoV-2 positivity was significantly higher for children with positive than negative serology results (12.3% vs 0.6%, p<0.001). Contact with a person with confirmed COVID-19 increased the odds of Reverse transcription-PCR positivity (OR 7.8, 95% CI 1.5 to 40.7) and serology positivity (OR 15.1, 95% CI 6.6 to 34.6). CONCLUSION: In an area heavily affected by COVID-19, after the peak of the first epidemic wave and during the lockdown, the rate of children with Reverse transcription-PCR SARS-CoV-2 positivity was very low (1.8%), but that of serology positivity was higher (10.7%). Most children with positive Reverse transcription-PCR results also had positive serology results. TRIAL REGISTRATION NUMBER: NCT04318431.

Antibiotic Resistance of Potential Otopathogens Isolated From Nasopharyngeal Flora of Children With Acute Otitis Media Before, During and After Pneumococcal Conjugate Vaccines Implementation.

BACKGROUND: To re-evaluate antibiotic strategies for acute otitis media (AOM) in young children, we analyzed the trends of nasopharyngeal carriage and antibiotic resistance of Streptococcus pneumoniae (Sp), Haemophilus influenzae (Hi) and Moraxella catarrhalis (Mc) isolated from young children with AOM during a 16-year period. METHODS: This cross-sectional study analyzed from 2001 to 2016 the nasopharyngeal carriage of Sp, Hi and Mc of young children with AOM. Medical history and physical findings were reported. Periods were defined by pneumococcal conjugate vaccine (PCV) introduction. We separately analyzed the 13-valent PCV (PCV13) period, which started after 2013. RESULTS: During the study, 12,973 children with AOM were enrolled by 138 pediatricians. By comparing the first and last PCV periods, the proportion of children in day care centers and that of AOM with conjunctivitis significantly increased. The proportion of penicillin nonsusceptible Sp carriage significantly decreased during the study, with 0.8% of penicillin-resistant strains isolated in the PCV13 period, but that of ß-lactamase-producing Hi continually increased to 23.6% in 2016. The level of Mc ß-lactamase-producing strains remained high (>97%). In the PCV13 period, the main predictors of ß-lactamase-producing Hi carriage were conjunctivitis (adjusted odds ratio = 6.0, 95% confidence interval [4.7-7.7]) and attending a day care center (2.4 [1.7-3.5]). CONCLUSIONS: In the PCV13 period, the proportion of penicillin-resistant Sp carriage was very low and that of ß-lactamase-producing Hi carriage did not exceed 20% among children with AOM and without conjunctivitis. Our results suggest that amoxicillin may remain the first-line antibiotic treatment for AOM in young children except for those with conjunctivitis, for which amoxicillin-clavulanate is still the best antibiotic.

Sickness behavior in feverish children is independent of the severity of fever. An observational, multicenter study.

BACKGROUND. OBJECTIVES: Behavioral changes in a febrile child are usually considered to stem from the fever. We studied sickness behavior (SB) in terms of its clinical components and its relation to fever. METHODS: This observational, multicenter study included children aged 6 months to 3 years who were either febrile (fever ≥12 hours, ≥ 39°C and ≥38°C at inclusion) or non-febrile and well. The child had to have been awake for the 2 hours preceding the consultation and cared for by the parent who brought him/her to the doctor. SB was evaluated according to 6 parameters over this 2-hour period: time spent playing, distance covered, time spent seeking comfort, time spent whining or crying, time spent in a state of irritation or of anger, most distorted facial expression. Two parameters were assessed for the 24-hour period preceding the consultation: time spent sleeping and appetite. The parent reported the degree of change in these parameters compared with the usual situation, using rating scales. RESULTS: 200 febrile children (most with nonspecific upper respiratory infections) and 200 non-febrile children were included. The mean values of the 8 parameters differed significantly (p<0.001) between the 2 groups and were independent of the height of fever at inclusion in the febrile children. In the study conditions, paracetamol failed to improve SB when the child was still feverish. CONCLUSION: The 8 parameters suggested that SB and fever are two independent manifestations that are activated simultaneously during an infection. This independence is in harmony with recommendations to treat the discomfort of SB and not the fever.

Efficiency of a clinical prediction model for selective rapid testing in children with pharyngitis: A prospective, multicenter study.

BACKGROUND: There is controversy whether physicians can rely on signs and symptoms to select children with pharyngitis who should undergo a rapid antigen detection test (RADT) for group A streptococcus (GAS). Our objective was to evaluate the efficiency of signs and symptoms in selectively testing children with pharyngitis. MATERIALS AND METHODS: In this multicenter, prospective, cross-sectional study, French primary care physicians collected clinical data and double throat swabs from 676 consecutive children with pharyngitis; the first swab was used for the RADT and the second was used for a throat culture (reference standard). We developed a logistic regression model combining signs and symptoms with GAS as the outcome. We then derived a model-based selective testing strategy, assuming that children with low and high calculated probability of GAS (<0.12 and >0.85) would be managed without the RADT. Main outcomes and measures were performance of the model (c-index and calibration) and efficiency of the model-based strategy (proportion of participants in whom RADT could be avoided). RESULTS: Throat culture was positive for GAS in 280 participants (41.4%). Out of 17 candidate signs and symptoms, eight were retained in the prediction model. The model had an optimism-corrected c-index of 0.73; calibration of the model was good. With the model-based strategy, RADT could be avoided in 6.6% of participants (95% confidence interval 4.7% to 8.5%), as compared to a RADT-for-all strategy. CONCLUSIONS: This study demonstrated that relying on signs and symptoms for selectively testing children with pharyngitis is not efficient. We recommend using a RADT in all children with pharyngitis.

Trends in antibiotic resistance of Streptococcus pneumoniae and Haemophilus influenzae isolated from nasopharyngeal flora in children with acute otitis media in France before and after 13 valent pneumococcal conjugate vaccine introduction.

BACKGROUND: After the implementation of pneumococcal conjugate vaccines (PCVs), the marked shift in Streptococcus pneumoniae (Pnc) serotype distribution led to a modification in pneumococcal antibiotic susceptibility. In 2011, the pattern of antibiotic prescription in France for acute otitis media in infants was greatly modified, with decreased use of third-generation cephalosporins and amoxicillin-clavulanate replaced by amoxicillin alone. To assess antibiotic strategies, here we measured the antibiotic susceptibility of Pnc and Haemophilus influenzae (Hi) isolated from nasopharyngeal flora in infants with acute otitis media in the 13-valent PCV (PCV13) era in France. METHODS: From November 2006 to June 2013, 77 pediatricians obtained nasopharyngeal swabs from infants (6 to 24 months old) with acute otitis media. The swabs were sent for analysis to the national reference centre for pneumococci in France. Demographics, medical history, and physical examination findings were recorded. RESULTS: We examined data for 7200 children, 3498 in the pre-PCV13 period (2006-2009) and 3702 in the post-PCV13 period (2010-2013). The Pnc carriage rate decreased from 57.9% to 54.2% between the 2 periods, and the proportion of pneumococcal strains with reduced susceptibility to penicillin or resistant to penicillin decreased from 47.1% to 39% (P < 0.0001). The Hi carriage rate increased from 48.2% to 52.4%, with the proportion of ß-lactamase-producing strains decreasing from 17.1% to 11.9% and the proportion of ß-lactamase-nonproducing, ampicillin-resistant strains remaining stable, from 7.7% to 8.2%. We did not identify any risk factor associated with carriage of ß-lactamase-producing Hi strains (such as daycare center attendance, otitis-prone condition or recent antibiotic use). CONCLUSION: In France, the nasopharyngeal carriage rate of reduced-susceptibility pneumococcal strains and ß-lactamase-producing Hi strains decreased in children with acute otitis media after 2010, the year the PCV13 was introduced. Accordingly, amoxicillin as the first-line drug for acute otitis media requiring antibiotics remains a valid choice.

Food intake during the previous 24 h as a percentage of usual intake: a marker of hypoxia in infants with bronchiolitis: an observational, prospective, multicenter study.

BACKGROUND: Hypoxia associated with bronchiolitis is not always easy to assess on clinical grounds alone. The aim of this study was to determine the value of food intake during the previous 24 hours (bottle and spoon feeding), as a percentage of usual intake (24h FI), as a marker of hypoxia, and to compare its diagnostic value with that of usual clinical signs. METHODS: In this observational, prospective, multicenter study, 18 community pediatricians, enrolled 171 infants, aged from 0 to 6 months, with bronchiolitis (rhinorrhea + dyspnea + cough + expiratory sounds). Infants with risk factors (history of prematurity, chronic heart or lung disorders), breast-fed infants, and infants having previously been treated for bronchial disorders were excluded.The 24h FI, subcostal, intercostal, supracostal retractions, nasal flaring, respiratory rate, pauses, cyanosis, rectal temperature and respiratory syncytial virus test results were noted. The highest stable value of transcutaneous oxygen saturation (SpO2) was recorded. Hypoxia was noted if SpO2 was below 95% and verified. RESULTS: 24h FI ≥ 50% was associated with a 96% likelihood of SpO2 ≥ 95% [95% CI, 91-99]. In univariate analysis, 24h FI < 50% had the highest odds ratio (13.8) for SpO2 < 95%, compared to other 24h FI values and other clinical signs, as well as providing one of the best compromises between specificity (90%) and sensitivity (60%) for identifying infants with hypoxia. In multivariate analysis with adjustment for age, SpO2 < 95% was related to the presence of intercostal retractions (OR = 9.1 [95% CI, 2.4-33.8%]) and 24h FI < 50% (OR = 10.9 [95% CI, 3.0-39.1%]). Hospitalization (17 infants) was strongly related to younger age, 24h FI and intercostal retractions. CONCLUSION: In practice, the measure of 24 h FI may be useful in identifying hypoxia and deserves further study.

Partial trisomy of chromosome 22 resulting from a supernumerary marker chromosome 22 in a child with features of cat eye syndrome.

Small supernumerary marker chromosomes are present in about 0.05% of the human population. In approximately 28% of persons with these markers (excluding the approximately 60% derived from one of the acrocentric chromosomes), an abnormal phenotype is observed. We report on a 3-month-old girl with intrauterine growth retardation, craniofacial features, hypotonia, partial coloboma of iris and total anomalous pulmonary venous return. Cytogenetic analysis showed the presence of a supernumerary marker chromosome, identified by fluorescence in situ hybridization as part of chromosome 22, and conferring a proximal partial trisomy 22q22.21, not encompassing the DiGeorge critical region (RP11-154H4 + , TBX1-). This observation adds new information relevant to cat eye syndrome and partial trisomy of 22q.

Bilateral periventricular heterotopias in an X-linked dominant transmission in a family with two affected males.

We report on the case of dizygotic twin boys, born prematurely to an asymptomatic mother. Bilateral periventricular heterotopias with enlarged ventricles were discovered at birth in both twins. One of the twins died prematurely of bronchopulmonary complications, and was shown to have several neuropathological anomalies (microgyria, thin corpus callosum, and reduced white matter). The surviving twin had mental retardation, without epilepsy. MRI of the mother showed asymptomatic periventricular heterotopias without ventricular enlargement. She had two affected daughters also with asymptomatic periventricular heterotopias. A point mutation in the last coding exon 48 of the Filamin A (FLNA) gene (7922c > t) was discovered on sequencing and segregated with the affected individuals. This family has a classical X-linked dominant BPNH pathology, with greater severity in males than females. The location of the FLNA mutation is discussed in light of the neuropathological anomalies and mental retardation in male patients.
