Prestretched airway smooth muscle response to length oscillation.

Airway smooth muscle (ASM) hyperconstriction is the cause of many respiratory diseases including asthma. In vitro testing has demonstrated that the active forces of ASM are reduced by length oscillation (LO) mimicking tidal breathing. In a previous study, we demonstrated that this force reduction can be further enhanced when superimposing oscillations (with certain frequencies and amplitudes) on this LO In contrast, it has been reported that pressurizing the lung may help in relieving asthmatic airway constrictions.

[A child with sepsis-associated encephalopathy].

Sepsis-associated encephalopathy (SAE) is a diffuse brain dysfunction due to a systemic response to infection. We report the case of a 4-year-old girl with fever and vomiting for 48h, brought to the university hospital of Grenoble because of vigilance disorders, loss of verbal fluency, and a cerebellar syndrome. She had a biological infectious syndrome.

[Organizing pneumonia occurring in a child with celiac disease].

Organizing pneumonia (OP), or bronchiolitis obliterans organizing pneumonia (BOOP), is rare, particularly in children. It affects the small airways and belongs to the group of interstitial lung diseases. Approximately 20 cases in children have been reported, the lack of knowledge of this disease making the diagnosis less likely.

[Sinus pericranii: a rare transcranial venous anomaly].

Introduction: Sinus pericranii is a rare midline cranial venous anomaly. It should be diagnosed radiologically. We report an asymptomatic case in a six-year-old female patient.
