Life-threatening subglottic hemangioma in an infant successfully treated with propranolol.

Subglottic hemangioma is a rare benign tumor in children. It causes an obstruction of the upper airway and can be life-threatening. Several therapeutic options have been used in the literature, including surgery. Currently, the treatment is essentially based on propranolol. We report the case of a 2-month-old female infant hospitalized for severe obstructive dyspnea secondary to a subglottic hemangioma. Diagnosis was confirmed by laryngoscopy and magnetic resonance imaging. The child underwent a tracheotomy and was treated with propranolol. The progression was favorable with regression of the subglottic hemangioma and improvement of laryngotracheal airway obstruction.

Staphylococcal scalded skin syndrome: An uncommon symptomatology revealing an immune deficiency.

Primary immune deficiencies associated with hyper-IgE syndrome are rare diseases with clinical features dominated by recurring cutaneous and visceral bacterial infections, particularly infections due to Staphylococcus species. Most of these infections are associated with milder inflammation compared to normal. We report a primary immune deficiency associated with a hyper-IgE syndrome revealed by a staphylococcal scalded skin syndrome in a 5-year-old girl. The patient presented with a severe staphylococcal infection with extensive skin lesions and disseminated intravascular coagulation. She received intravenous fluids to compensate for fluid losses and anti-staphylococcal antibiotics. Coagulopathy was also corrected. However, the progression was rapidly fatal.

[A rare cause of recurrent meningitis in children: cochleovestibular dysplasia]. / Une cause rare de méningite récurrente chez l'enfant: la dysplasie cochléovestibulaire.

Recurrent bacterial meningitis is an uncommon disease of childhood. It occurs most often in children who have an underlying predisposing disorder that can result from anatomic fistula or immunodeficiency. Cochleovestibular dysplasia is a rare malformation of the inner ear that is often associated with translabyrinthine cerebrospinal fistula and then can cause recurrent bacterial meningitis. We report an unusual case of recurrent meningitis revealing cochleovestibular dysplasia in a 9-year-old child. The malformation was confirmed by imaging and the child had surgery. The outcome was favourable with no recurrence of meningitis during the 3 years after the operation.

Acute disseminated encephalomyelitis following herpes simplex encephalitis.

Acute disseminated encephalomyelitis is an acute immunomediated demyelinating disorder of the central nervous system, usually encountered in children or adolescents and characterized by multifocal neurologic deficits of rapid onset. It is often preceded by various infectious diseases or vaccination, but acute disseminated encephalomyelitis developing after herpes simplex encephalitis is rare. We report such a case in a 2-year-old girl which illustrates the importance of MRI features to consider acute disseminated encephalomyelitis in a patient who develops neurologic signs after the onset of HVS encephalitis.

[Opsoclonus-myoclonus syndrome associated with Mycoplasma pneumoniae infection]. / Syndrome opsoclonie-myoclonie associé à une infection à Mycoplasma pneumoniae.

UNLABELLED: Mycoplasma pneumoniae infection is associated with various manifestations involving the central nervous system but it has never been reported as a potential aetiology of opsoclonus-myoclonus syndrome (OMS) in children. OBSERVATION: We report on a case in a 4-year-old girl who presented neurological manifestations compatible with an OMS, after a respiratory tract disease. Aetiological investigations revealed M. pneumoniae infection as specific IgM were present in the serum (Elisa). Evolution after corticosteroid, intravenous immunoglobulins and macrolide therapy was favourable as clinical symptoms disappeared. After a 12-month follow-up, the patient has no neurological sequela. CONCLUSION: M. pneumoniae infection should be added to the list of causes to be screened in OMS. Its pathophysiology remains unknown but may involve a dysimmune postinfectious mechanism.
