Portable device for generation of ultra-pure water vapor feeds.

A portable device for the generation of co-feeds of water vapor has been designed, constructed, and evaluated for flexible use as an add-on component to laboratory chemical reactors. The vapor is formed by catalytic oxidation of hydrogen, which benefits the formation of well-controlled minute concentrations of ultra-pure water. Analysis of the effluent stream by on-line mass spectrometry and Fourier transform infrared spectroscopy confirms that water vapor can be, with high precision, generated both rapidly and steadily over extended periods in the range of 100 ppm to 3 vol.

[-Neonatal Kasabach-Merritt syndrome healed by complete surgical excision of the angioma-].

Background: Kasabach-Merritt syndrome is an infrequent combination of a giant hemangioma and severe thrombocytopenia. This syndrome may be life-threatening. There are various but no definitive methods of treatment.

[Familial hemophagocytic lymphohistiocytosis. Differential diagnosis with secondary hemophagocytic syndromes].

We report 2 cases of familial hemophagocytic lymphohistiocytosis in two children, hétérozygous twins, born from consanguine parents. This disease is characterised by disseminated lymphohistiocytic infiltrates with hemophagocytosis, that most commonly involves bone marrow, spleen, lymph nodes, liver and central nervous system. Differential diagnosis is difficult with infection-induced hemophagocytic syndromes.

[Management of newborn infants in maternity-neonatal intensive care units].

Background: Although in utero transfer seems actually the safest option when risk factors are identified, specialized transport teams remain important to consider for the neonatal overall management.

Subjects: From January 1988 through December 1992, 692 transports of 838 neonates were prospectively studied to determine effectiveness and safety of the Hospital Lenval's neonatal transport team.

Results: Neonatal transports were required respectively for prematurity (46.
