Laser temperature programmed desorption: A flexible technique to study ion-surface interaction.

Understanding the physical-chemical processes ruling the interaction of particles (atoms, molecules, and ions) with surfaces is fundamental in several research fields, such as heterogeneous catalysis, astrochemistry, and nuclear fusion. In particular, the interaction of hydrogen isotopes with plasma facing materials represents a high-priority research task in the fusion community. Such studies are essential to ensure the successful operation of experimental fusion reactors, such as the tokamak ITER.

Management of respiratory distress following prehospital implementation of noninvasive ventilation in a physician-staffed emergency medical service: a single-center retrospective study.

Background: Noninvasive ventilation (NIV) is recognized as first line ventilatory support for the management of acute pulmonary edema (APE) and chronic obstructive pulmonary disease (COPD) exacerbations. We aimed to study the prehospital management of patients in acute respiratory distress with an indication for NIV and whether they received it or not.

Methods: This retrospective study included patients ≥18 years old who were cared for acute respiratory distress in a prehospital setting.

[Position of a patient in emergency situations : lots of experiences, few evidences].

In emergency situations, regularly trained technical skills return as automatisms. This is so with the positioning of our critical patients. According to their signs and symptoms (e.

Hamman's syndrome associated with pharyngeal rupture occurring during childbirth.

Hamman's syndrome is the classical association of subcutaneous emphysema and pneumomediastinum, with or without pneumothorax. Its onset during the expulsive phase of childbirth is exceptional. We report here the first case associated with pharyngeal rupture at the level of the piriform sinus and describe the warning signs and the management by endoscopy.

EEG-mediated diagnosis of an unusual presentation of SSPE.

Objective: To highlight the role of EEG in the diagnosis of SSPE.

Methods: EEG was performed in an 18 month old girl who had a 1 week history of repeated episodes of sudden flexion of the head and trunk and frequent falls.

Results: EEG abnormalities consisted of stereotyped, generalized and synchronous high amplitude periodic complexes.

[Pseudoperiodic and paroxysmal electroencephalographic activities].

Periodic and paroxysmal EEG patterns are frequent and easily recognized. They often correlate with particular neurological or systemic conditions. We propose a reclassification and critical examination of these periodic EEG patterns by reviewing the original work presented by J.

[Congenital virilizing adrenal hyperplasia due to 11 beta-hydroxylase deficiency. Study of eleven cases (author's transl)].

Eleven cases of congenital virilizing adrenal hyperplasia are studied. This study leads to point out some peculiar characteristics: virilization of external genitalia in girls is most usually important; arterial hypertension is delayed, usually after some years; plasma androgens and desoxycortisol are highly elevated; plasma 17-hydroxyprogesterone is slightly elevated and this may be misleading; good results of treatment which must preferably use hydrocortisone since plasma cortisol is sometimes low; long-term risks in treated children include chronic hypertension in both sexes, advanced puberty in girls and pubertal gynecomastia in boys.
