    Characteristic phenotype in congenital nephrotic syndrome (1995)

    Notizen: Abstract We present three children with congenital nephrotic syndrome and previously undescribed facial features. These include: (1) small mouth (intercommissural distance mouth (intercommissural distance 〈3rd percentile); (2) tented upper lip; (3) small nose (interalar distance −2 SD below mean); (4) fullness of cheeks giving a ‘jowly’ appearance; (5) overhanging outer thirds of upper eyelids. These features may reflect prolonged tissue oedema and protein malnutrition in utero and early life. Conclusion Characteristic facial features in congenital nephrotic syndrome may reflect intra-uterine malnutrition.

    Technegas and Pertechnegas particle size distribution (1995)
    Springer

    Notizen: Abstract Technegas and Pertechnegas are radioactive aerosols produced in a commercial generator and used for lung scintigraphy. The aerosols are produced by first evaporating to dryness standard technetium-99m generator eluate (99m-TcO4 in normal saline) in a graphite crucible (thesimmer stage) and then heating this to 2500° C (the „burn” stage). The aim of this work was to measure the particle size distributions of these agents and relate this to regional lung deposition. Factors that may vary during production of the aerosol in routine use were investigated to determine whether they influenced the particle size. Activity size distributions were measured using a serial wire-screen diffusion battery. The Technegas size distribution was approximately log-normal with an activity median diameter of 158 nm and a geometric standard deviation of 1.5. The results for Pertechnegas were similar. The median size increased with the number of simmers and with the time from generation. The increase in size with the number of simmers is thought to be due to the increased salt content in the crucible prior to the „burn”. The predicted lung deposition is 37% in the alveolar region and 5% in the bronchial region. Significant changes in deposition are not predicted over the range of particle sizes measured.
