From 2015 to 2017, 3197 interpretable Bordetella polymerase chain reaction (PCR) tests were performed for 2760 children presenting to our tertiary university hospital. Requests mainly came from the emergency department (62%) and for children older than 1 year (68%). Only 32 PCR (1%) results were positive, mainly in children younger than 1 year (n = 29/32, 90.6%; p<0.001). When focusing on the PCR indications in 2017, we found the requests were mainly based on nonspecific respiratory symptoms and were clinically unjustified in 383 cases (39%). Pediatricians overused Bordetella PCR in clinical practice. They should reserve their requests for cases of young children with symptoms suggestive of respiratory illness and/or incomplete pertussis immunization., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest with the subject of this study., (Copyright © 2021 French Society of Pediatrics.

We aimed to describe the real-life role of high-flow nasal cannula (HFNC) for bronchiolitis in infants under 3 months of age admitted to three general pediatric departments during the 2017-2018 epidemic period. We retrospectively assessed the clinical severity (Wang score) for every 24-h period of treatment (H0-H24 and H24-H48) according to the initiated medical care (HFNC, oxygen via nasal cannula, or supportive treatments only), the child's discomfort (EDIN score), and transfer to the pediatric intensive care unit (PICU). A total of 138 infants were included: 47±53 days old, 4661±851.9 g, 70 boys (50.7%), 58 with hypoxemia (42%), Wang score of 6.67±2.58, 110 (79.7%) staying for 48 consecutive hours in the same ward. During the H0-H24 period, only patients treated with HFNC had a statistically significant decrease in the severity score (n=21/110; -2 points, P=0.002) and an improvement in the discomfort score (n=15/63; -3.8 points, P<0.0001). There was no difference between groups during the H24-H48 period. The rate of admission to the PICU was 2.9% for patients treated for at least 24 h with HFNC (n=34/138, 44% with oxygen) versus 16.3% for the others (P=0.033). Early use of HFNC improves both clinical status and discomfort in infants younger than 3 months admitted for moderately severe bronchiolitis, whatever their oxygen status., (Copyright © 2020 French Society of Pediatrics.

We report the case of an 18-month-old infant with severe serotype 3 adenovirus pneumonia, exceptionally associated with hemophagocytic syndrome. Treatment included cidofovir and mechanical ventilation for 13 days. The child developed chronic respiratory insufficiency due to bronchiectasis and bronchiolitis obliterans., (Copyright © 2020 French Society of Pediatrics. Published by Elsevier Masson SAS.

Non accidental intoxication due to child abuse is rare and its frequency is likely underestimated because it is difficult to diagnose. Here, we report a case of voluntary repeated exposure to lithium in an infant, for whom the clinical manifestations were convulsions. Toxicological analysis was very helpful for documenting lithium exposure during the assumed period of time. Interpreting the results of hair analysis, a simple and minimally invasive examination, is tricky at this age, but it can facilitate the differentiation of acute versus chronic exposure. Although infrequent and underestimated, lithium should be considered as a cause of intoxication in a previously healthy child with acute seizure., (Copyright © 2020 French Society of Pediatrics.

Outdoor pollution is a complex mix of more than 200 air contaminants. Among these pollutants, ozone, nitrogen dioxide and fine particles may generate bronchial inflammation and hyperreactivity. The hypothesis that pollution contributes to the development of asthma in children is based on epidemiological, clinical and experimental data. Many risk factors during the in utero and postnatal period have been identified in the aetiology of childhood asthma. During pregnancy, outdoor pollution was identified as a causal factor of respiratory disease in neonatal cohort studies. Several epidemiological studies also demonstrate that outdoor pollution is a trigger of asthma exacerbations. This review aims to highlight the current knowledge on outdoor pollution and asthma., (Copyright © 2019. Published by Elsevier Masson SAS.)

Introduction: There are few studies that have investigated the long-term outcome of children who have been victims of shaken baby syndrome (SBS). However, the consequences appear to be significant and the data available from a social point of view are scarce. The main objective of this study was to define the medical and social outcome in 2016 of the infants who were victims of SBS and admitted to one of the Marseille university hospitals. The number of patients followed by a specialized team was evaluated along with their clinical state, living conditions, and whether a social support system such as the Child welfare system had been put into place., Method: The study was retrospective and descriptive. Patients under 1 year of age who were hospitalized between January 2005 and December 2013 and manifested clinical and paraclinical characteristics enabling the diagnosis of SBS were included in the study. The diagnosis was certain, probable, or possible according to the definitions given by the consensus of the 2011 shaken baby health authority conference (HAS)., Results: Eighty babies qualified for the study, three of whom died in intensive care. Only ten of these patients (12.9%) had regular (annual) neuropediatric check-up during the whole study period. Thirty-seven patients (48%) had an annual neuropediatric check-up during the first 2 years only following the diagnosis. Only 12 of the children (15.6%) were still being followed after the age of 6. The children were followed up on average for 2.5 years (29.6 months). In 24 cases (31%), the last medical visit revealed an abnormal neurological examination including multiple disabilities due to spastic quadriplegia and severe intellectual deficit, which led to total dependency in half of these cases. Forty-four patients (57%) had a normal neurological examination. Concerning the babies' social outcome, 50 patients (64.9%) had returned home, 12 (15.6%) benefited, from educational assistance at the patient's home (AEMO) following the ruling of a children's judge, and 19 (24.7%) were still placed in foster care (ASE). The average foster care placement lasted 34.7 months., Discussion and Conclusion: Long-term medical follow-up for children having sustained serious head injury as a result of abuse is inadequate. Sequelae such as multiple disabilities are less frequent than described in the literature. According to this study, a longer-term follow-up is necessary for children suffering from sequelae such as learning disabilities than what is actually possible in our center., (Copyright © 2018.

The frequency of body piercing has increased in France over the past few years, particularly among teenagers. Piercing can be performed at different sites on the body, especially in the cartilage of the ears. We relate two cases of Pseudomonas aeruginosa chondritis. A 10-year retrospective study at the Marseille University Hospital found no additional pediatric cases. These infectious complications can sometimes be necrotizing. It is therefore important to inform the medical staff on the hygiene measures that need to be respected and the patients on the treatment to follow after the piercing as well as the signs to watch for, possibly indicating chondritis. The esthetic consequences depend on early diagnosis., (Copyright © 2017 Elsevier Masson SAS. All rights reserved.)

Objective: A management protocol for infants hospitalized for acute bronchiolitis, established after the study conducted in our unit in 2012, recommends a chest X-ray when the clinical course is unusual or if a differential diagnosis is suspected. The goal of this study was to evaluate professional practices after the introduction of this new management protocol., Study Design: Retrospective descriptive study in two pediatric units from October 2013 to March 2015, including infants (0-23 months) hospitalized for their first episode of acute bronchiolitis without any underlying chronic condition., Result: Overall, 599 infants were included (median age, 3.7 months, 54 % boys). Nearly six out of ten (n=355, 59.3 %) had at least one chest radiograph (38.5 % fewer than in 2012). It was abnormal in 96.3 % of cases, revealing distension and/or bronchial wall thickening (56.7 %), focal opacity (23.5 %), or atelectasis (19.5 %). An X-ray was performed out of the recommendations in 42.5 % of cases. The chest X-ray result led to management changes in 52 infants with prescription of antibiotics for pneumonia (86.5 %) and allowed the diagnosis of heart disease in one case (0.2 %). Management of acute bronchiolitis (X-ray and antibiotics) was statistically different between the two pediatric units., Discussion: This protocol led to a significant decrease in the number of chest X-rays. However, many are still performed out of the recommendations, resulting in an increase of antibiotic use for pneumonia., Conclusion: The decrease in use of chest X-rays in acute bronchiolitis for hospitalized infants was significant but remains insufficient., (Copyright © 2016 Elsevier Masson SAS.

Introduction: Even if there are HAS (French National Health Authority) guidelines on shaken baby syndrome, many other child abuse situations are not included in these recommendations. The aim of this study was to invent the complementary exams in cases of child abuse in France and compare the practice to existing guidelines., Material and Methods: This was a multicenter study by email to 128 French hospitals (35 university hospitals and 93 general hospitals) that receives children in emergency and hospitalization settings. Three child abuse clinical situations were included in a clinical case multiple-choice format concerning the further explorations. We described the main results and evaluated their adherence to the HAS protocol for case 1., Results: Of 128 hospitals surveyed, 104 responded, for an 81 % response rate, which corresponded to 274 doctors. Analysis of the results showed great heterogeneity in practices. The majority of physicians (99 %) performed systematic explorations in the situation of physical abuse, while only 27 % undertook such exams in situations of serious neglect. The situation of sexual abuse was the most consensual in terms of diagnostic tests for the detection of sexually transmitted diseases, but other types of associated abuse were not sought. In the first case, the HAS guidelines were respected in less than half of the cases for all complementary exams except the eye fundus exam. Abdominal imaging was insufficiently performed (40 % of cases). Examinations that were not indicated were still prescribed. Moreover, siblings under 2 years of age were examined in only one-third of cases (n=88/274; 32 %). Practices were not influenced by the age of the child., Conclusion: This study illustrates the heterogeneity in the use of complementary exams in cases of child abuse in France. Common protocols throughout the country would be useful, standardizing the most relevant exams for potential medical-legal issues, and facilitating exchanges concerning practices between different centers., (Copyright © 2016 Elsevier Masson SAS.

We report the case of a 21-month-old child suffering from pulmonary fibrosis, who presented with acute respiratory distress and liver damage, due to an accidental overdose of intravenous lipid emulsion. This poisoning is a rare entity, whose potential severity and almost exclusive iatrogenic effect deserve to be remembered., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Unlabelled: Pediatric obesity may induce multiple complications, including cardiovascular and metabolic problems in adulthood. It may also cause respiratory disorders, which are not usually the first-intention diagnosis by physicians. The aim of this study was to evaluate how investigations had been performed in obese children referred to Timone Pediatric Hospital., Patients and Methods: A retrospective study of children referred to our department for severe non-syndromic obesity was conducted. The clinical features comprised history, anthropometric parameters, dietary habits, acanthosis nigricans, symptoms of obstructive sleep apnea syndrome (OSAS) as well as the paraclinical endocrine markers, blood gases, and sleep recordings., Results: Of 102 patients (mean age, 10.5±3.3 years; BMI Z-score, 4.52±1.5), 29.4% had OSAS symptoms (n=30). Nine had a pathological polysomnography confirming OSAS. Eight of them required ventilation: these children were the most severe with an earlier weight gain (2.17±1.2 years vs. 4.0±2.2 years; P=0.01) and a higher BMI Z-score (7.2±2.3 vs. 4.3±1.1; P=0.027). Obesity hypoventilation syndrome (OHS) was diagnosed in 3.9% of these children (n=4)., Conclusion: Diagnosis of OSAS and OHS, often overlooked in obese children, requires a systematic approach and early clinical detection of respiratory disorders. Better accessibility to sleep respiratory explorations would improve quality of care for these children., (Copyright © 2015. Published by Elsevier SAS.)

Introduction: By the end of 2011, 275,000 children in France were included in the Aide sociale à l'enfance (ASE, Child Welfare System). Half of these children were entrusted to public care. There is limited data on these children. The MDPH (Maison départementale des personnes handicapées) is an administrative body assisting in the care of disabled children, through material, financial, and human means. Analyzing MDPH medical records can provide medical information about these children. The aim of this study was to describe the characteristics of children left to the ASE with a record at MDPH in Bouches-du-Rhône., Methods: We extracted administrative data from two registers, the ASE register and the MDPH register. The MDPH medical files of each patient were analyzed and their medical information was coded: gestational age, deficiencies, and pathologies., Results: In Bouches-du-Rhône, 2965 children were entrusted, 506 (17%) of whom were known by the MDPH: 30.6% of the entrusted children known by MDPH were taken into foster care and 48% were in residential group homes. Half of the MDPH notifications concerned a referral to a school or medico-social institution. By analyzing the medical data, we observed an average of 2.1 deficiencies per child. The types of deficiencies were distributed as follows: 35.9% were psychological deficiencies, 26.4% were speech deficiencies, and 21.6% were intellectual cognitive deficiencies. The most common pathology was mental and behavioral disorder (71% of diagnoses)., Discussion: The MDPH notification rate in children entrusted to public care was seven times higher than in the general population. Overall, explaining the relation between child abuse and neglect and disability is difficult. The psychopathology of these children is complex. These results show the importance of specific medical monitoring for these children., (Copyright © 2015. Published by Elsevier SAS.)

Introduction: This study aimed at assessing parents' knowledge and perception in relation to their child's condition when arriving at the emergency ward following an asthma attack. The overall objective was to determine how parent education could be improved., Materials and Methods: This study was conducted over 9 months as a multicenter descriptive and qualitative study based on a self-administered questionnaire for parents of asthmatic children, aged 2-15 years., Results: The questionnaire was delivered to 88 children out of 1472 (6%). Approximately 69% of the children included in the study presented with partially controlled or uncontrolled asthma. Fifty percent of the patients were insufficiently monitored and without therapy. Half of the parents said they had never received any information concerning their child's condition. The majority (86%) did not know the basic cause of the disease, 30% percent were unable to detect the features of clinical exacerbation, and 17% were not using an adequate emergency protocol. The illness experience was relatively easy for two-thirds of the children and the parents' perceptions were in line in 50% of the cases., Discussion: Knowledge of parents and their children suffering from asthma is insufficient for optimal control and disease management. Instructions on detecting the signs of asthma severity as well as the establishment of an individualized emergency protocol and medical follow-up should be of prime concern and could reduce emergency department use., Conclusion: Doctors have a key role to play in educating and explaining disease characteristics to patients and their families. Therapeutic education also needs to be intensified., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

Acute epiglottitis has become an exceptional observation in pediatrics. The introduction of Haemophilus influenzae type B vaccine changed the morbidity, mortality, and microbiology of this disease.

Unlabelled: The 2000 French guidelines for acute viral bronchiolitis management underlined clinical criteria for hospitalization. We aimed to assess the impact of these guidelines on admission rates in pediatric emergency departments., Methods: A prospective multicentric observational study was conducted over 24h in 66 pediatric emergency departments. Questions were asked about the structure, the course of care, clinical data, resource utilization, and hospitalization or discharge of every patient under 2 years of age with acute viral bronchiolitis. An open-ended question allowed clinicians to explain the reason for hospitalization. Multivariable logistic regression analyses were performed to identify independent risk factors for severe disease to assess potential clinical factors associated with hospitalization. Responses were compared using the Student t-test and the Chi(2) test., Results: Of 338 patients enrolled, 145 (45.1%) were admitted. Clinical criteria were associated with hospitalization: clinical deterioration (OR: 3 [95% CI: 1.0-8.5], p=0.04), respiratory rate more than 60/min (OR: 3.4 [95% CI: 1.3-8.8], p=0.02), age under 6 weeks (OR: 29.8 [95% CI: 7.0-125.4], p<0.001), oxygen saturation less than 94% (OR: 15.8 [95% CI: 4.2-60.1], p<0.001), food intake less than 50% of the usual intake (OR: 4.9 [95% CI: 2.2-10.9], p<0.001), and age between 6 weeks and 3 months (OR: 3.2 [95% CI: 1.4-7.2], p=0.007)., Conclusion: The clinical criteria of the 2000 French guidelines influence hospitalization for acute viral bronchiolitis in pediatric emergency departments. However, other criteria are cited in about one-third of the patients., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

Every winter, numerous infants are hospitalized for acute bronchiolitis. The severity criteria and symptomatic treatment are well known, with chest physiotherapy codified in 2000 by the French Health Authority (HAS) consensus conference (with techniques varying from one country to another) and becoming nearly systematic for the treatment of bronchial obstruction in infants. However, is this treatment really effective and legitimate for acute bronchiolitis? The objective of this study was to review the main studies on this subject. Few studies are available and most have a low level of evidence. However, they all tend to agree that chest physiotherapy does not change the natural history of the disease and most particularly the duration of hospitalization. Therefore, it does not seem that the prescription of chest physiotherapy in infant acute bronchiolitis is recommended., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)

Background: Asthma is the most common chronic disease in childhood. With its high economic burden, it is considered a disease of major public health importance by the World Health Organization. The link between respiratory tract infections and acute exacerbation has been recognized for a long time. The aim of this retrospective study in routine care was to evaluate our practices concerning microbiological prescriptions in children hospitalized for asthma exacerbation., Study Design: All children aged from 2 to 15 years hospitalized for asthma exacerbation between January 2010 and December 2011 in our unit were included in the study. Microbiological prescriptions, their indications, their results, and their cost were studied., Results: One hundred ninety-seven children were included in the study. A potential causative agent was sought in 79.7% of the children (n=157) by immunofluorescence assay (IFA) and/or polymerase chain reaction (PCR). The main indications were upper airway infections, hypoxemia, and pneumonia. Viruses were detected in 23.8% of them (30/126). Mycoplasma pneumoniae was detected by PCR in only 3.2% of these patients (4/125). No other bacterial agent was identified. There was no correlation between the severity of asthma exacerbation and the microbiological diagnosis of infection. The results did not influence the therapy given. These prescriptions represented a substantial cost for each child., Conclusion: These analyses do not seem to have a real advantage for the patient except for epidemiology. It would be important to conduct a new study analyzing the role of rhinovirus, and of other viruses such as coronavirus, bocavirus, and enterovirus, not routinely investigated in our hospital, and to question the value of these costly microbiological tests., (Copyright © 2014 Elsevier Masson SAS.

Recurrent tracheoesophageal fistula (TEF) is possible after repair of congenital esophageal atresia. The frequency of recurrent TEF is observed in about 10% of the cases. Within a cohort of 67 children with type III esophageal atresia repaired between 1998 and 2009, we aimed to identify the number of children with recurrent TEF, the risk factors for this condition, and the treatment proposed. The sex ratio was 1.7. Surgery was performed between 4 and 36 hours of life. Five children (7.5%) had a recurrent TEF, usually during the first 3 months, revealed by respiratory symptoms related to feeding in some cases. We noted that recurrent TEF was more frequent with anastomotic leakage (P=0.09) or postsurgical pneumothorax (P<0.01). The diagnosis was made in four cases out of five by a methylene blue test performed during a tracheobronchial endoscopy. Surgical treatment was noted in four children, with three postsurgical secondary effects. One child was treated by endoscopy and an esophageal clip. With a median follow-up of 52 months, no recurrence was noted. The recurrence of TEF may be linked to postsurgical events. Diagnosis is not easy and treatment is not clearly codified. Endoscopic treatment may be an advantageous option to surgery, likely with less morbidity., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)

We report on the case of a 15-year-old boy with massive hemoptysis caused by anastomosis between bronchial and pulmonary arteries, successfully treated with embolization. No similar case was found in the literature, likely because of the high mortality rate of this type of malformation., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)

Nicolau syndrome is a rare, potentially severe complication that may occur after any drug injection, particularly after intramuscular injection. It is characterized by the acute onset of cutaneous and soft-tissue aseptic necrosis. Here, we report the case of a 14-year-old boy diagnosed with Nicolau syndrome on the right lower limb, after a benzathine-penicillin intramuscular injection for suspected rheumatic fever. The short-term progression was marked by uncomplicated rhabdomyolysis and the constitution of homolateral testicular torsion. The cutaneous-muscular disorders evolved favorably under symptomatic treatment. We discuss this insufficiently known complication of intramuscular injection, which may motivate reduced use of this route of drug administration in children and strict adherence to the procedure. Furthermore, it is important to note that Nicolau syndrome may evolve to homolateral testicular torsion, as, to the best of our knowledge, is reported for the first time in this case., (Copyright © 2014 Elsevier Masson SAS.

Recommendations for the use of diagnostic testing in low respiratory infection in children older than 3 months were produced by the Groupe de Recherche sur les Avancées en Pneumo-Pédiatrie (GRAPP) under the auspices of the French Paediatric Pulmonology and Allergology Society (SP(2)A). The Haute Autorité de santé (HAS) methodology, based on formalized consensus, was used. A first panel of experts analyzed the English and French literature to provide a second panel of experts with recommendations to validate. Only the recommendations are presented here, but the full text is available on the SP(2)A website., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)

The aim of this study was to evaluate the medium-term outcome (health status, medical and surgical French National Health Authority-recommended follow-up, and quality of life) of children born with type III esophageal atresia (EA). Previous events (during the perinatal period, associated abnormalities, respiratory and digestive complications) of children treated for type III EA at the Marseille university hospitals between 1999 and 2009 were noted. Parents completed a standardized questionnaire concerning the health of their children during the previous year, and a quality-of-life questionnaire (PedsQL 4.0) was also completed by children aged more than 8 years. Among the 68 children treated, 44 responded to our solicitation (mean age, 7.6 years; range, 3-12.8 years). Previous important events were : pneumonia(s) (65%), asthma before the age of 3 years (66%), hospitalization for a respiratory event (45%), fundoplication (20%), and esophageal dilatation (45%). We noted current chronic cough (16%), asthma (30%), dysphagia (39%), and symptomatic gastroesophageal reflux (9%). National guidelines were not respected, except for the surgical indications in children aged less than 6 years. The quality-of-life scores (n=43 children) were similar to healthy controls but were negatively influenced by a gastrostomy procedure (P=0.020), pneumonia (P=0.013), and hospitalization due to a respiratory event (P=0.006) or a digestive event (P=0.010), and also by current asthma (P=0.004). In conclusion, despite recurrent respiratory or digestive symptoms and inadequate recommended follow-up, the quality of life of children treated for type III of EA is good., (Copyright © 2013.

We report the case of late vitamin K deficiency bleeding (VLDB), with appropriate but insufficient prophylaxis, secondary to extrahepatic cholestasis. Late VKDB is rare today but serious, with a risk of intracranial hemorrhage in more than half of the cases.

Objective: To describe the chest radiographs of infants hospitalized for acute bronchiolitis and to assess whether patient management changed after radiography., Study Design: All infants hospitalized in our pediatric unit with a first episode of acute bronchiolitis from October 2010 to March 2012 were included in the study. Infants with chronic disease or transferred from a pediatric intensive care unit were excluded. The following data were collected: sex, age, neonatal history, atopy, tobacco exposure, admission criteria, treatment, laboratory parameters, ultrasonography and its outcome, results of chest radiography on admittance, the reason for a second chest radiograph, change in management as a result of the radiograph., Results: The study comprised 232 infants (median age 2.2 months, boys 56%, positive respiratory syncytial virus 73.4%). Among them, 227 children had a routine chest radiograph revealing distension and/or bronchial wall thickening (n=141, 62.4%), focal opacity (19.9%), or atelectasis (17.7%). This radiograph led to the prescription of antibiotics in six patients (2.6%) and allowed the diagnosis of vascular abnormality to be made in one case (0.4%). Thirty-five patients (15.4%) had a second chest radiograph during their hospitalization owing to oxygen dependency (n=21), respiratory distress (n=11), persistent fever (n=2), or no reason specified (n=1). Pneumonia (n=7) and/or atelectasis (n=15) were then found in 62.9%. Patient management (antibiotics, postural maneuvers) was modified in six patients (17.1%)., Conclusions: Routine chest radiographs contribute only partially to the treatment of infants hospitalized for acute bronchiolitis. However, radiography is useful when the hospitalized child does not improve at the expected rate or if the disease is severe. The indication of chest radiography in infants hospitalized for acute bronchiolitis should be discussed on a case by a case basis., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

Airplanes are widely used by families and their children and pediatricians are increasingly asked to answer questions on this subject. The main purpose of this study was to evaluate the knowledge of pediatricians in this field except for medical transportation. Pediatricians belonging to the AFPA, the SFP, the SNPEH, or the SP2A were emailed a questionnaire on the physiological particularities of airborne transportation, contraindications to flight related to diseases (infections, diabetes, sickle-cell anemia, respiratory diseases, etc.) and the possible medication intake on board. Among the 232 responders, 82.3% had an exclusive hospital practice and 65% were specialized in more than one area of medicine. Regarding contraindications to flying, the rate of correct answers varied from 14 to 84% with divided opinions regarding respiratory and hematological pathologies. However, contraindications related to infections were well known. Items related to oxygen therapy raised questions as 35-68% of pediatricians stated that they could not answer. On the whole, this work demonstrated very fragmented knowledge on this topic., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

Acute viral bronchiolitis affects infants, is frequent, and can be severe. Its treatment is only based on symptoms. Hypertonic saline (HS) may act favorably in this situation by fighting virus-induced dehydration of the airway liquid surface. Because of an osmotic action, HS attracts the water from the epithelial cells and improves mucociliary clearance. Five double-blind placebo-controlled studies concerning hospitalized infants with acute viral bronchiolitis showed that repeated nebulizations of 3% HS induce a 20% improvement in the clinical severity score and reduced the hospital length of stay by 24h. Tolerance is excellent. On the other hand, a few questions remain unresolved: what is the optimal salt concentration? What is the recommended nebulizer? What is the best frequency for nebulizer use? Can nebulized HS be used at home? What are the results with systematic physiotherapy when HS is used?, (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

We report on 2 recent and misleading cases of infants hospitalized for Chlamydia trachomatis pneumonia: the first one, 29 days old, had a clinically relevant presentation but was born by caesarean section; the second one, 43 days old, presented with acute respiratory distress. Microbiological diagnosis was achieved by the specific detection of C. trachomatis by molecular biology from a nasopharyngeal sample. These 2 clinical cases illustrate the need to systematically look for C. trachomatis during bacterial-like pneumonia in infants under 3 months of age., (Copyright © 2011 Elsevier Masson SAS.

Mushroom intoxication due to Amanita proxima poisoning is characterized by moderate gastrointestinal symptoms, followed by severe acute renal failure and sometimes by hepatic cytolysis. This syndrome was described in the 1990s in the southeast of France; we report here the first pediatric case, requiring dialysis but achieving complete recovery. The mother of this 11-year-old boy, who had eaten the same mushrooms but in smaller quantities, had only biological renal and hepatic involvement., (Copyright © 2011. Published by Elsevier SAS.)

We report 2 cases of children with group A streptococcus pyogenes pleuropneumonia, in one child associated with Kawasaki disease and in the other with streptococcal toxic shock syndrome. These 2 features, with theoretically well-defined clinical and biological criteria, are difficult to differentiate in clinical practice, however, likely due to their pathophysiological links. In case of clinical doubt, an echocardiography needs to be performed to search for coronary involvement and treatment including intravenous immunoglobulins, and an antibiotic with an anti-toxin effect such as clindamycin has to be started early., (Copyright © 2011 Elsevier Masson SAS.

Streptococcus pyogenes or group A streptococcus (GAS) is responsible for serious invasive infections with a risk of secondary infection in patients with more contact than in the general population. Regardless of clustering, few intrafamilial invasive infections have been reported despite a recent increase in the incidence of invasive GAS disease. We report the cases of two brothers, one a boy of 8.5 years with toxic shock syndrome with no bacteria identified and the second, 1 week later, his 14.5-year-old brother in hospital for sepsis due to GAS. The occurrence of a confirmed case of invasive GAS and a probable case within such a short period met the definition of clustered cases. Both brothers showed no risk factors for invasive disease and no gateway including skin was found. Antibiotic therapy was initiated in the family as recommended by the French Higher Council of Public Hygiene., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)

Kawasaki disease is a well-known disease in young children. However, it can also affect older children. The aim of this study was to determine the different characteristics of Kawasaki disease in older children and young adults. This is a descriptive, retrospective, and multicenter study including all cases of Kawasaki disease occurring in children over 8 years and adults hospitalized at children's or adult Hospitals, in Marseille, France, between 1999 and 2009. The clinical, biological, prognostic, and therapeutic data were reviewed for each case. Over a 10-year period, 98 patients were hospitalized for Kawasaki disease. Six cases were aged between 8 years and 1 month and 21 years and 7 months. All patients showed a classic form of the disease with associated organ damage in 5 patients. A cardiac problem was present in 5 cases with 2 patients needing intensive care. The median time to diagnosis and treatment was 11.2 days, with all patients initially diagnosed erroneously. Current treatment guidelines were applied in 2 patients. Kawasaki disease in children over 8 years and adults under 30 years has a worse prognosis than in young children even though clinical features are atypical. It is rarely seen by clinicians in this age group, causing a delay in diagnosis, the main factor of the poor prognosis. The diagnosis of Kawasaki disease must be raised when predisposing factors are present in this group., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)

We report a case of spontaneous hemothorax in a 9-year-old boy due to costal exostosis in the context of hereditary multiple exostosis disease. This is an unusual complication, whose pathophysiology remains unclear., (Copyright © 2010 Elsevier Masson SAS. All rights reserved.)

Botryomycosis is an uncommon bacterial infection. It occurs in two forms: cutaneous and visceral. Fewer than 30 pediatric cases have been reported. We present the first case of a 14-day-old newborn with botryomycosis revealed by four tumefactions located in the inguinal and popliteal hollows, without a biological inflammatory syndrome. Pathological examination of the sample demonstrated botryomycosis. The culture collection found Staphylococcus aureus. Progression was favorable with appropriate prolonged antibiotic therapy. Predicting factors such as immunodeficiency or cystic fibrosis were excluded., (Copyright © 2010 Elsevier Masson SAS. All rights reserved.)

Objectives: The obligation for BCG vaccination, suspended in July 2007, was replaced by a vaccination targeting children with a high risk of tuberculosis. The purpose of this study was to assess the vaccination rate of infants living Marseilles and its suburbs who had criteria for BCG vaccination., Material and Methods: This observational study consisted in interviewing the parents of children born after the suspension of the obligatory BCG vaccination and admitted for a medical visit at the Pediatric Emergency Department of the Timone-Enfants University Hospital between 1 December 2008 and 31 March 2009. For each child, we noted the demographic data, the criteria for BCG eligibility, the vaccination status, and, when the child was not vaccinated but at risk for tuberculosis, the information received by the family on the vaccination., Results: A total of 224 out of 271 eligible children were included (82.6%; mean age, 7.1 ± 4.9 months). One hundred and fifty-seven infants had at least one criterion for BCG vaccination; 116 of them were vaccinated (73.9%). The number of criteria for the vaccination did not influence the vaccine rate. Families of non-vaccinated high-risk children (n=41) had been informed about BCG in 39% of the cases. BCG was planned in 11 of these 41 infants., Conclusion: Eighteen months after suspension of the obligation for BCG vaccination, our results are encouraging but underline the need for improving information to families concerned by this new vaccination policy., (Copyright © 2010 Elsevier Masson SAS.

The aim of our study was to determine the different characteristics of infective endocarditis in children without underlying heart disease. This was a descriptive, retrospective study including all cases of infective endocarditis without underlying heart disease occurring in children under 18 years of age, hospitalized at the Timone Children's Hospital in Marseille, France, between 1997 and 2008. The clinical, microbiological, and echocardiography data; treatment; and outcome were reviewed for each case. Over an 11-year period, 26 children were hospitalized with infective endocarditis. Eleven children (7 boys) had no underlying heart disease (42 %). Their mean age was 8 years and 3 months. Underlying conditions including neoplasm, preterm birth, and central venous catheter were found in 6 cases. A heart murmur was observed in 82 % of the children. A microorganism was isolated in 10 children (91 %). Staphylococcus aureus was the most common agent (45 %), followed by fungi (18 %). Echocardiography detected cardiac complications in 7 cases (64 %). Ninety-one percent of the children received intravenous antibiotics for a mean duration of 45 days. Eighty-two percent of our patients required surgical intervention. In our series, 91 % of the patients met the modified Duke criteria defining infective endocarditis. In-hospital mortality was 11 %. Embolic complications were seen in 5 cases (45 %), patients whose cultures yielded S. aureus or fungal organisms were more likely to present complications. Infective endocarditis without heart disease has particular features that differ from those of congenital heart disease. This diagnosis must be considered when predisposing factors are present., (Copyright (c) 2010 Elsevier Masson SAS. All rights reserved.)

In France, half of hospital admissions for asthma concern children and the rates of hospitalization, decreasing in adults, are stable in children. Most admissions for asthma exacerbation are avoidable with appropriate disease management. The objective of this study was to describe the characteristics of children admitted for asthma. The study was carried out in 14 pediatric units over 1 year. Children aged 3 years and over who were hospitalized for an asthma exacerbation were included. Data from 727 hospitalizations were collected. In 48% of the hospitalizations, children were 3-5 years old. Asthma was undiagnosed at the time of the admission in 27%. Among children with diagnosed asthma, 57% had already been admitted to the hospital for asthma exacerbation, 37% had been admitted to the hospital or emergency department during the last year, and the control of asthma in the previous month was unacceptable in 46%; 11% had received an oral and written self-management action plan. This study underlines the need to strengthen the efforts to encourage improvement of the therapeutic education of asthmatic children in order to decrease the risk of hospitalization for exacerbation of asthma., (Copyright 2010 Elsevier Masson SAS.

Background: The 2000 French Consensus Conference for Acute Viral Bronchiolitis management underlined clinical practice recommendations., Objective: To assess the impact of these guidelines on management of acute bronchiolitis, 3 and 8 years after publication., Methods: A standardized questionnaire was mailed to 762 general practitioners (GPs) in 2003 and 800 GPs in 2008. It described two clinical case scenarios (moderate acute viral bronchiolitis and severe acute bronchiolitis) and inquired about the physician's conduct in each case. The primary outcome was the percentage of responders who described patient management in accordance with current guidelines: correct diagnosis and treating the patient symptomatically in an outpatient setting in the first case and correct diagnosis in addition to requiring an inpatient setting for the second case. Secondary outcome was the percentage of responders who would have given unnecessary or potentially harmful treatments. Physician responses in 2003 and 2008 were compared using the Student t-test and the Chi(2) test. Multivariate analysis was conducted to assess the potential factors associated with good adherence to guidelines., Results: Nearly 25% of the questionnaires were returned in 2003 and 2008. Patient management was described in accordance with the guidelines in only 6% in 2003 and 20% in 2008 (p< or =0.001). Unnecessary treatments were prescribed in 77% in 2003 vs 60% in 2008 (p<0.001) and potentially dangerous treatments in 38% in 2003 vs 22 % in 2008 (p=0.006). Using multivariate analysis, the GP's age was inversely correlated with adherence to clinical recommendations (adjusted odds ratio [adOR]=0.93; 95% CI=0.87-0.98; p=0.01). Fifty-four percent of GPs reported knowing these guidelines, but only 57% of them declared that the latter has modified their practice., Discussion: GPs are still prescribing unnecessary or even potentially dangerous treatments for bronchiolitis. On the other hand, severe cases are correctly diagnosed and well managed in an inpatient setting., Conclusion: Three and 8 years after their publication, adherence to guidelines is insufficient., (Copyright 2009 Elsevier Masson SAS.

Accidental drownings are severe and sometimes mortal events in children. Our study aims to better clarify the epidemiology and the respiratory complications of these accidents in our hospital. We led a retrospective study over 10 years concerning the children hospitalized for accidental drowning in our hospital centre. Age at the moment of the accident, sex, history of accident, hospitable care, thoracic imaging and neurological outcome of the children were studied. In total, 83 children were hospitalized (5 years on average, 70% being boys). The drowning especially took place in fresh water (71%), particularly in swimming pools (51.8%). Stages III and IV of drowning concerned 40.9% of the population. The coverage was the following one: admittance in ICU 57.8%, mechanical ventilation 34.9%, oxygen therapy 16.9%, antibiotics 87.9%. A normal chest x-ray was present in 45.7% of the cases. Drowning in fresh water, especially in contaminated fresh water (canal, WC, etc.), induced atelectasis (10.8%), whereas drowning in sea water induced diffuse infiltrates (8.4%). Aspiration pneumonia (33.7%) was present in both cases and a pulmonary oedema (6%) was only noticed during stage IV drowning. The secondary infections were rare (1 case was suspected and another probable). A child presented a secondary acute respiratory distress syndrome (1.2 %). Finally, 7 deaths (8.4%) and 1 case with severe neurological sequelae (1.2%) were noted. Accidental drowning causes important consequences in children. The long-term respiratory outcomes have not been properly studied. Prevention of such accidents is based on parental vigilance during their child's bathe., (Copyright 2009 Elsevier Masson SAS.

Aims: In the past few years, survival has increased for people with cystic fibrosis (CF). Diabetes is an important complication of CF caused by pancreatic insufficiency, which reduces insulin secretion. Because of increased longevity of patients with CF, the prevalence of CF-related diabetes (CFRD) has increased. CFRD is associated with increased mortality and morbidity. Several studies have reported a decline in nutritional and pulmonary status 2-4 years before the diagnosis of CFRD. The introduction of insulin treatment can produce clinical improvement in weight and lung function. The oral glucose tolerance test is currently the reference method in screening for CFRD, but the current definition of diabetes based on the 2-h post-load plasma glucose level may not be the most accurate method for early detection of glucose tolerance abnormalities in CF. The continuous glucose monitoring system (CGMS) has been described as a useful tool for early detection of hyperglycemia in the CF patient. We tested the CGMS in CF patients with unexplained alteration of their general status. The aim of this study was to assess the value of the CGMS in this population., Methods: An annual OGTT (following World Health Organization recommendations) was conducted as a screening test to identify CFRD in patients aged over 10 years or patients aged under 10 years with a poorer clinical status. The CGMS was performed in patients with unexplained worsened clinical status and without diabetes in OGTT., Results: Forty-two patients aged from 8.5 to 19 years were screened using OGTT for CFRD. According to ADA criteria, 23 patients (54.8%) displayed normal glucose tolerance, 14 (33.3%) impaired glucose tolerance, and 5 diabetes (11.9%). Out of 37 nondiabetic, the CGMS was used in 20 patients with unexplained altered general status. The CGMS revealed peaks of glucose values greater than 2 g/L in 16 patients, 9 patients with normal glucose tolerance, and 7 patients with impaired glucose tolerance. The mean CGMS glucose and time of glycemic monitoring above 1.4 g/L increased in patients with peaks greater than 2 g/L compared to patients without peaks (p=0.0016 and p=0.0069 respectively). After analysis of the CGMS, the prevalence of diabetes increased from 11.9 to 50%. Three patients aged less than 10 years with a normal OGTT profile presented glycemic peaks greater than 2 g/L during CGMS., Conclusion: CGMS revealed more glucose metabolism abnormalities than OGTT in patients with unexplained altered general status.

Unlabelled: Chicken pox is usually considered a benign viral affection; however, possible infectious complications are observed. Although cutaneous infections are well described, bacterial pneumonia with empyema is more exceptionally reported., Purpose: To describe the clinical characteristics of bacterial pneumonia with empyema associated with chicken pox., Methods: This descriptive multicenter retrospective study was based on a questionnaire sent by Internet to 30 French pediatric and pediatric respiratory hospital wards., Results: We found 4 cases of children (mean age, 19 months) presenting during the chicken pox eruption concomitant bacterial pneumonia with empyema. The average time of diagnosis was 4.5 days after the beginning of the eruption. All the children were febrile and had an average pulsed oxygen saturation of 87%. The inflammatory syndrome was constant with a mean C reactive protein of 253 mg/l. Group A Streptococcus was identified in 3 cases out of 4. Admission to an intensive care unit was necessary for 3 children, 1 of them requiring mechanical ventilation. No clinical or radiological sequelae were observed during the complete year of follow-up., Conclusion: Bacterial pneumoniae with empyema are not current complications of chicken pox but have to be sought when prolonged fever and/or alteration of the health status occurs during chicken pox eruption.

Spontaneous pneumomediastinum is a rare entity in children, especially in young infants. We report the case of a 4-month-old infant with a massive spontaneous pneumomediastinum caused by acute viral bronchiolitis. Treatment including bed rest, codeine for its antitussive action, and nitrogen washout resolved the pneumomediastinum within 3 days. In the literature, cases of pneumomediastinum in very young infants are exceptional. To our knowledge, codeine has never been used in this situation. Nitrogen washout is also rarely used because of poorly demonstrated efficacy.
