    Notes: Abstract Type 1 allergy against natural rubber latex is an increasing problem in health care workers and children with spina bifida or urogenital malformations. The aim of our study was to evaluate the prevalence of latex IgE antibodies and cross-reacting fruit antibodies in patients with spina bifida compared with atopic and non-atopic controls. Risk factors for sensitization should be determined. Sera of 148 patients with spina bifida and 98 controls (44 with atopy) were screened for IgE antibodies against latex, banana and kiwi by fluorescence enzyme immunoassay (CAP system). Atopies, allergic symptoms after latex contacts and the number of operations were compiled by a questionnaire. Patients with spina bifida developed latex IgE antibodies (≥0.7 kU/l) more frequently (40.5%) than atopic children (11.4%) or healthy controls (1.9%). All 18 symptomatic patients belonged to the spina bifida group and had high values of latex antibodies. The risk for developing latex antibodies increases with the number of operations. There was no difference in the history of atopic diseases and in a screening test of IgE antibodies against inhalative allergens between latex sensitized and not sensitized children with spina bifida. Antibodies against banana were more frequent in the latex sensitized children with spina bifida. (18.3% vs 3.4%, P = 0.002). Conclusion The high prevalence of latex antibodies in children with spina bifida justifies a primary prophylaxis by avoiding latex contacts, especially during anaesthesia and surgery, a correlation between the number of operations and the development of latex antibodies exists.

    Notes: The Late Proterozoic Pedro Leopoldo facies (Bambuí Group) in the vicinity of Belo Horizonte, Brazil, comprises alternating laminated microsparitic limestones (10–35 mm thick beds) and fibrous limestones (10–55 mm thick). The latter are composed of a mosaic of sparry calcite crystals. These irregularly crosscut rays and fans are composed of feathery precursor crystal bundles with squared-off growth zones. Ghosts of an original fibrous mineral, hexagonal in cross-section, are visible. The petrographic characteristics, very high strontium content and low magnesium content of the fibrous beds, as well as microspar beds, strongly argue for an original aragonitic mineralogy. The rays are interpreted as having formed by precipitation at the sediment-water interface, whereas the micrite was precipitated from the water column prior to deposition on the sea floor. The lack of emergence features suggests widespread aragonite precipitation under persistently subtidal conditions.

    Latex allergy in spina bifida patients – prevention by primary prophylaxis (1998)

    Notes: Background The effect of latex prophylaxis has not been investigated in spina bifida children, a high-risk group for latex allergy. As repeated operations have been identified as a major cause of latex sensitization, we wanted to find out whether primary latex prophylaxis during surgery could prevent latex allergy in children with spina bifida. Methods In December 1995, we established latex-free surgery and anesthesia for all patients with spina bifida regardless of their sensitization to latex. Twelve children born after that date (mean age 1.2 years, mean ntmiber of operations 3.3, range 1 -7) were tested for specific IgE against latex until December 1997 (ImmunoCap, Pharmacia, Uppsala, Sweden) and compared with eight children born before December 1995 (mean age 1.3 years, mean number of operations 3.6, range 1–8), in whom a test for latex IgE had been done before the age of 2 years. Results Before we established primary prophylaxis, three of seven children with spina bifida (38%) were sensitized to latex until the age of 2 years. After the establishment of a latex-free operating theater for spina bifida patients, none of the 12 patients were sensitized to latex despite up to seven operations in each child. Conclusions Primary latex prophylaxis during surgery can prevent latex sensitization in young spina bifida patients.

    Description / Table of Contents: Summary A method is described for assessing the distribution of blood flow within organs. Microspheres, 5–50 μ in diameter, labelled with a beta-emitting isotope were injected into the left ventricle of experimental animals. The distribution of the indicator within the tissues, which is assumed to represent the regional distribution of flow, was visualized and measured quantitatively by autoradiography. Local flow rates in areas of about 1,2 mm in diameter could be determined. Application of the technique for the study of regional myocardial and renal circulation is demonstrated.
    Notes: Zusammenfassung Eine Methode zur Bestimmung der Durchblutungsverteilung in differenziert strukturierten Organen wird beschrieben. J-131 markierte Partikel, deren Durchmesser den der Capillaren übertrifft, werden in den linken Ventrikel von Versuchstieren injiziert. Unter bestimmten Voraussetzungen repräsentiert die Verteilung dieses nicht rezirkulierenden Indicators im Systemkreislauf und innerhalb einzelner Organe die regionale Durchblutungsverteilung. Die Verteilung des markierten Materials im Gewebe wird autoradiographisch dargestellt und durch densitometrische Auswertung der Autoradiogramme quantitativ gemessen. Aus der lokalen Indicatorkonzentration konnen relative und — bei Kenntnis der Gesamt-durchblutung des untersuchten Organs — absolute Durchblutungsgrößen innerhalb 1,2×1,2 mm großer Areale bestimmt werden. Die Anwendung dieses Verfahrens zur Untersuchung der regionalen Myokarddurchblutung und der intrarenalen Durch-blutungsverteilung wird an Beispielen dargestellt.

Alle Systeme zeigen endotherme Effekte, die sich bei Annahme einer polymeren Netzwerkstruktur der Schmelzen auf die Verzerrungsenergie bei Einbau unterschiedlich großer Ionen zurückführen lassen.
    Notes: The integral enthalpies of mixing of the liquid mixtures AgCl + Ag2Se, AgI + Ag2Se, AgCl + Ag2Te, AgBr + Ag2Te and AgI + Ag2Te were determined in an isoperibolic calorimeter. The systems have endothermic effects which can be explained by a misfit energy, due to the substitution of ions of different size in the polymeric network of these melts.

Cp data, calculated from spectroscopic measurements, showed close agreement with the experimental values.New preparation methods for the compounds P4S4 with terminal sulfur, β-P4S4 and β-P4S5 are given. The DSC measurements were used to discuss the phase diagram P—S.
