[Acute idiopathic eosinophilic pneumonia in a teenager]. / Le cas clinique du mois. Pneumonie éosinophilique idiopathique aiguë chez une adolescente.

Acute idiopathic eosinophilic pneumonia is a very rare cause of interstitial lung disease in children. Pathophysiological mechanisms and etiology remain poorly understood. It manifests as a febrile dyspnea, progressively worsening. Chest X-ray, performed as first-line, shows bilateral infiltrates. The chest CT confirms a diffuse infiltrative pneumopathy and the bronchoalveolar lavage demonstrates the presence of alveolar hypereosinophilia. The exclusion of other causes of alveolar eosinophilia confirms the diagnosis. A ventilatory support is very often necessary. Systemic corticosteroids provides a spectacular clinical improvement, without recurrence.

La pneumonie éosinophilique idiopathique aiguë est une cause très rare de pneumopathie infiltrante diffuse de l'enfant. Le mécanisme physiopathologique et l'étiologie sont mal connus. Elle se manifeste par une dyspnée fébrile, s'aggravant progressivement. La radiographie thoracique, réalisée en première intention, montre des infiltrats bilatéraux. Le scanner thoracique confirme la pneumopathie infiltrante diffuse et le lavage broncho-alvéolaire démontre la présence d'une hyperéosinophilie alvéolaire. L'exclusion d'autres causes d'éosinophilie alvéolaire permet de confirmer le diagnostic. Un support ventilatoire est très souvent nécessaire. Une corticothérapie systémique permet une amélioration clinique spectaculaire, sans récidive.

[Spondylodiscitis in children: a review. A propos of two cases]. / La spondylodiscite chez l'enfant: a propos de deux observations.

Spondylodiscitis is defined as an infection of the intervertebral disc and the adjacent vertebral bodies. It represents, at the most, 2-4% of osteoarticular infections in children and its clinical presentation is often insidious. The specific condition of the young child (isolated discitis) is explained by some anatomical peculiarities. We report two cases of spondylodiscitis in children of different ages and review the pediatric characteristics, the role of imaging, the bacteriological diagnosis and the management of this disease.

[Clinical case of the month. Left recurrent neck abscess revealing a fourth branchial cleft fistula]. / Le cas clinique du mois. Abcès cervical gauche récidivant révélateur d'une fistule de la quatrième fente branchiale.

The fourth branchial cleft fistula, which can be the origin of a recurrent left neck abscess, is a rare congenital malformation. Its diagnosis can be difficult. A ten-year-old girl presented with a left painful swelling of the neck. At ultrasonography and tomodensitometry, the diagnosis of thyroglossal cyst was suspected. Antibiotics were prescribed before surgical resection. The intervention was successful and the peroperative macroscopic aspect of the lesion suggested a dermoid cyst. Four months later, the same symptoms reappeared with fever. An intravenous antibiotic therapy was started while a magnetic resonance imaging demonstrated a possible aero-digestive tract fistula. Two days later, the patient developed an aero-cutaneous fistula. Oral antibiotics were started. Five months later, the girl came back for a second recurrence. A few days after her admission, she developed again an aero-cutaneous fistula. The diagnosis of surinfected fourth cleft fistula was made. An antibiotic therapy was started until the second intervention. After discussion about embryology, we describe the physiopathology, the differential diagnosis and the management of a fourth branchial cleft fistula causing recurrent left neck abscess.

[A clinical case of spontaneous involution of systemic cat scratch disease]. / Involution spontanée d'une forme systémique de maladie par griffade de chat: à propos d'un cas.

Typical Cat-scratch disease (CSD) manifests as regional lymphadenopathy following cat scratch and sometimes associated with mild fever. There is a lot of atypical manifestations and some of those have systemic involvement. Hepatosplenic CSD is a systemic presentation associating fever of unknown origin with nodules in the liver and/or the spleen. Ultrasound abdominal examination shows nodules (3-30 mm) in the spleen and/or in the liver. Diagnostic is based on serology for B henselae (always IgG + and sometimes IgM +), or polymerase chain reaction (PCR) on the liver to test for the presence of B henselae. Hepatosplenic CSD is rare and therefore underdiagnosed. There is no consensus about the treatment but most of the authors suggest to treat with rifampicine. We report a case of a 4-years-old girl presenting with fever of unknown origin (FUO), high inflammatory markers with normal leukocytosis and hepatosplenic nodules. The diagnosis of CSD was made retrospectively. Evolution was favourable even though no specific antibiotic treatment for Bartonella henselae was administrated.

[Dengue shock syndrome]. / Le cas clinique du mois. A propos d' une fièvre "importée.

Célia, 21 month-old child, presented to our pediatric clinic a few months ago with a fever of unknown origin after a stay in St-Domingue with her parents. Complementary investigations led to a diagnosis of Dengue Fever. The condition, not very frequent and thus not well known in our countries, represents a major world health problem especially because of the global failure of prophylactic measures. If the disease is self-limited in most cases, severe form can occur, with significant mortality and morbidity. Delay in diagnosis and treatment of these severe cases is often fatal.

Early skin sensitization to aeroallergens.

BACKGROUND: Early detection of aeroallergen sensitization is important as a prognosis factor but may be more difficult in young children. OBJECTIVE: We sought to demonstrate that skin sensitization to aeroallergens was present in a selected group of 0-2-year-old children and that it was associated with environmental exposure and a family history of allergic disease. METHODS: Data on exposure and history were extracted from the files of 824 children seen in the asthma clinic and who were skin tested to a panel of aero- and food allergens. RESULTS: Forty percent of our children demonstrated atopy, 28% were sensitized to aeroallergens, the majority of which to house dust mite. Higher sensitization rates were found in children with large weals to histamine (P<0.001) and in those who slept with soft toys [odds ratio (OR) 1.45, 95% confidence interval (CI) 1.02-2.08]. With a definition of sensitization including the size of the weal to histamine, there was a negative association with a personal history of eczema only (OR 0.66, 95% CI 0.45-0.99). There was no gender-dependent effect and no association with day-care attendance. CONCLUSION: This is one of the largest studies to evaluate skin testing in a selected population of young children. We found a high prevalence of sensitization to aeroallergens, which was associated with exposure to soft toys. Further follow-up of this population will allow assessment of the predictive value of this sensitization.

[Limp with fever in adolescent: about 2 cases of pyomyositis]. / Boiterie fébrile chez l'adolescent: à propos de 2 observations de pyomyosite.

The authors report on 2 cases of limp with fever in adolescents, which developed after vigorous physical activity and were due to pyomyositis. Clinical, biological and radiological findings of the disorder are reviewed. Treatment is discussed. Early diagnosis and treatment are crucial for good prognosis.

[Pet turtle and septicemia: what is the relationship?]. / Tortue d'eau et septicémie chez un nourrisson de 4 mois: quel rapport ?

We report the case of a four months old girl who suffered from a Salmonella pomona's septicemia. The source of contamination was the pet turtle recently acquired by her parents. If the pet turtle-associated salmonellosis is still rare in our country, the high rate of carriage of this germ by these exotic pets and the potential severity of the human disease justify an epidemiological survey. People with immature or weakened immune systems should avoid contact with reptiles.

[Infant respiratory distress revealing Jeune syndrome]. / Détresse respiratoire du nourrisson révélant un syndrome de Jeune.

Jeune syndrome (asphyxiating thoracic dystrophy) is a rare autosomal recessive osteochondrodysplasia with a variable degree of severity, clinically characterized by respiratory distress with a narrow chest and limb shortness. The reported incidence is one to five in 500,000 live births. Most patients develop severe respiratory failure during the first 2 years of life, leading to death in 60-80 % of cases. Survivors may suffer from renal, hepatic, or pancreatic complications. Expanding thoracic surgery can be used for severe cases. We describe the case of an 18-month-old boy who developed mild respiratory distress. The patient showed typical radiological features of Jeune syndrome: narrow thorax with short ribs and trident appearance of the pelvis. This case underscores the value of the right interpretation of the chest radiograph of the infant with a respiratory distress syndrome.

[Necrotizing pneumonia in children: apropos of 4 cases]. / Pneumonie nécrosante de l'enfant: à propos de 4 cas.

OBJECTIVES: To describe the necrotizing pneumonia in children, a severe affection which prevalence seems to increase; to review literature. PATIENTS AND METHODS: We report 4 cases of necrotizing pneumonia: symptoms, agents, diagnostic tools, treatment and long term evolution. RESULTS: In 2 cases, pneumatoceles could be seen at chest X-ray. Two patients presented a deficiency of anti-pneumococcal antibodies. Three needed insertion of a pleural chest tube of whom 1 had a resection of a small piece of necrotic lung. Duration of hospitalisation is longer than in uncomplicated pneumonias. CONCLUSION: Necrotizing pneumonia is a severe affection. Diagnosis has to be made by lung CT. Long term evolution is excellent in pediatric population with serious management at hospital.

[Pleural effusion in childhood: management algorithm]. / Epanchement pleural de l'enfant: Proposition d'un algorithme de prise en charge.

Based on an increased prevalence of empyema in children,we reviewed the literature on the diagnosis and management of this affection. A retrospective study of 11 children admitted to our hospital in 2003 shows a prolonged hospitalisation (median 18 days) even with adequate treatment. Based on our experience and data from the literature, we propose a management algorithm to allow treatment of children admitted ith pleural effusion.

[Two case reports of meningococcemia. Review of the literature on chronic meningococcemia]. / À propos de deux cas de méningococcémie. Revue de la littérature sur la méningococcémie chronique.

INTRODUCTION: Neisseria meningitidis is a Gram-negative bacteria that can be highly pathogenic in humans and responsible for life-threatening and acute diseases. In a few cases, it can lead to an atypical form of sepsis-acute, subacute, or chronic-which, even if progression is slower, may carry the same risks for patients as conventional acute forms. CASES: Case 1 presented with recurrent fever, polyarthralgia, and generalized macular rash. Case 2 had fever for the previous 10days with neck pain and macular rash. Blood cultures were positive for group B meningococcus in both cases. Polymerase chain reaction (PCR) analysis for the same pathogen was also positive in the cerebrospinal fluid (CSF) of Case 2. Following intravenous antibiotic treatment, the progression was favorable in both cases. DISCUSSION: Chronic meningococcemia is characterized by a triad of clinical features, including a fever lasting for at least 1week, arthralgia, and a cutaneous rash. This condition evolves positively without any sequelae if treated properly. PCR and blood culture are two complimentary tools that support the diagnosis. CONCLUSION: Meningococcal infection can manifest in a variety of ways. Chronic meningococcemia diagnosis should be considered in a triad of prolonged fever, rash, and arthralgia. Better access to state-of-the-art techniques such as PCR is recommended in the future so as to provide optimal care of patients suffering from this condition.

Chronic respiratory failure due to toxic epidermal necrosis in a 10 year old girl.

Toxic epidermal necrosis is a severe mucocutaneous disease with a high mortality rate. A third of the patients surviving the acute phase will develop pulmonary complications. The most frequent complication is bronchiolitis obliterans. Despite well-conducted treatment, in most cases, lung injury often leads to chronic respiratory failure. We describe here the case of a young patient that presented a toxic epidermal necrosis at the age of 3 years. Poor therapeutic compliance result in chronic respiratory failure and after 7 years of follow-up, pulmonary transplant remains the only long-term alternative. Close monitoring of respiratory symptoms in the course of toxic epidermal necrosis, intense treatment as soon as they appear and a long-term follow-up are essential to postpone chronic respiratory failure.

Cutaneous lesions of disseminated cryptococcosis as the presenting manifestation of human immunodeficiency virus infection in a twenty-two-month-old child.

We report the case of a 22-month-old African boy with cutaneous lesions as the predominant feature of disseminated cryptococcosis (positive blood and cerebrospinal fluid cultures) and as the presenting manifestation of severe vertically acquired HIV infection (CDC C3 category). To our knowledge these cutaneous lesions have never been reported as the initial manifestation of AIDS in children.

An early MR observation of carotid involvement by retropharyngeal abscess.

We report early carotid involvement by retropharyngeal abscess in a 4-year-old boy. MR imaging showed enhancement of the wall and narrowing of the lumen of the internal carotid artery, which were thought to reflect spasm and/or arteritis. Prompt treatment may have prevented hemorrhagic and neurologic complications.

Release of deuterated nonenal during beer aging from labeled precursors synthesized in the boiling kettle.

The use of labeled nonenal enabled the demonstration that the appearance of the cardboard flavor in finished beer comes from lipid auto-oxidation during wort boiling and not from lipoxygenasic activity during mashing. Free trans-2-nonenal produced by linoleic acid auto-oxidation in the kettle disappears, owing to retention by wort amino acids and proteins. This binding linkage protects trans-2-nonenal from yeast reduction but is reversible, allowing release of the compound at lower pH during aging. Labeled trans-2-nonenal is detected after aging when deuterated precursors form in the boiling kettle. The amount of alkenal released correlates with the concentration of reversible associations in the pitching wort. This work brings new illumination to the formation of trans-2-nonenal and overturns many previous hypotheses. It also explains why a reduction in the beer pH intensifies the cardboard flavor.

Foreign body aspiration in childhood: management algorithm.

Foreign body inhalation is still a major cause of morbidity and even mortality in the under-fives. To reduce its frequency, more severe preventative measures must be imposed and to allow for early diagnosis, a low threshold for bronchoscopy is necessary. This retrospective study is based on 33 children referred to us for suspicion of inhaled foreign body. Symptomatology, clinical and paraclinical data are reviewed. Based on our practice and on the experience gained from the literature, we propose a management algorithm which will need to be further assessed by a prospective study.

[Quality of the care of the pediatric patient admitted to the emergency room]. / Qualité de la prise en charge de l'enfant admis en salle d'urgence polyvalente.

AIM: By a prospective study, authors tried to analyse the quality of management of the pediatric patient admitted in the emergency department. POPULATION AND METHODS: One hundred admission files were prospectively analysed for characteristics of age (mean age: 70 months), effectiveness of measurement of physiological parameters, evaluation of appropriateness of nursing management according to recorded parameters, length of stay in the emergency department according to the need for hospitalization, blood tests, X-rays and the seniority of the attending medical staff. RESULTS: Parameters were not, or only incompletely, recorded in 65 files. . Although all were recorded in the remaining 35 files, subsequent management was inadequate in seven cases. Mean length of stay in the emergency department was 116 minutes, influenced by the need for hospitalization (145 minutes compared to 102 minutes for the non-hospitalized children), timing of admission (mean: 125 minutes from 8 am to 6 pm, compared to 94 minutes from 6 pm to 8 am), need for blood tests, X-rays or both (mean: 122, 107 and 170 minutes respectively, compared to 55 minutes when no complementary exam was asked) and seniority of attending medical staff (mean: 65 minutes for permanent staff compared to 116 minutes for fellows). CONCLUSIONS: Measurement of physiological parameters must be standard practise in the management of pediatric patients admitted to the emergency department and must lead to appropriate management without undue delay. In order to reach this goal, emergency departments should be more adequately staffed with nurses and senior doctors specifically trained in the care of the pediatric patient. Blood tests and X-rays should be more readily available.

[Laryngitis revealing bacterial tracheitis in a five-year-old child]. / Laryngite révélatrice d'une trachéite bactérienne chez un enfant âgé de cinq ans.

CASE REPORT: We report the case of a five-year-old boy with clinical features of croup and left lower lobe pneumonia. Response to inhaled adrenaline and dexamethasone was incomplete and he developed respiratory distress. Direct laryngoscopy performed in the operating room showed mild glottic and subglottic inflammation. On bronchoscopy, there was thick pus coming from the left lower lobe. He was intubated for three days and regular toilet brought back thick pus. Tracheal fluid culture grew Haemophilius influenzae. COMMENTS: We suggest that he had bacterial tracheitis but that the tracheal involvement was not prominent at the time of diagnosis. CONCLUSION: Laryngoscopy and bronchoscopy in specialized surroundings should be considered for each child with croup unresponsive to conventional treatment, especially in case of lower respiratory tract involvement.

[Acute left-side appendicitis: diagnostic contribution of tomodensitometry]. / Appendicite aiguë d'expression clinique gauche: apport diagnostique de la tomodensitométrie.

BACKGROUND: Some cases of left-sided appendicitis related to malrotation or situs inversus have been reported. Another type of left-sided appendicitis is reported. CASE REPORT: A 9 year-old boy was admitted suffering from a 2-day history of severe left-sided abdominal pain of the lower quadrant with fever at 38 degrees C. He presented abdominal tenderness and guarding, maximal in the left lower quadrant. His leukocyte count was 22,000/mm3. Ultrasonography showed a digestive tubular structure with thick walls in the left lower quadrant. CT scan revealed a dilated right-sided appendix with localized perforation, whose extremity was located in the left lower quadrant along the lateral wall. The diagnosis was confirmed by median laparotomy. CONCLUSION: Left-sided appendicitis can also be related to a dilated right appendix with its extremity in the left lower-quadrant near the lateral wall. CT scan can then be helpful for diagnosis when ultrasonography remains unconclusive.
