    Notes: Metoprolol, a widely prescribed β-adrenergic receptor blocker, has occasionally been associated with a diversity of cutaneous reactions. We present a 79-year-old male patient with erosive lichen planus (LP) on the feet and hands who was successfully treated with topical tacrolimus. Six months after the lesions had been cured the patient received the β-receptor blocker metoprolol for the treatment of hypertonus. Within only 2 weeks of metoprolol intake the erosive lesions on the palms and feet recurred. After discontinuation of the drug and repetitive topical treatment with tacrolimus a complete remission of the lesions could be achieved. The recurrence of erosive LP probably secondary to metoprolol and the therapeutic success of topical tacrolimus in the treatment of LP are discussed.

    Notes: A 2-year-old girl with Moya Moya disease who had relapsing cerebrovascular strokes presented with loose skin folds, ‘chicken’ skin appearance and perforating elastosis serpiginosa-like lesions in the genitocrural region. Histologically, calcified material perforating the epidermis and adjacent short curled and mineralized elastic fibres suggested a variant of pseudoxanthoma elasticum (PXE). As PXE is known to be caused by various mutations in the transmembrane transporter ABCC6 gene, we hypothesized that a novel ABCC6 mutation may underlie this unique combination of PXE and elastopathic vascular damage. Therefore, the complete ABCC6 coding region of the patient and her parents was screened for genetic alterations. No bona fide disease-causing mutation of ABCC6 could be found in the child and in her parents. However, two novel allelic amino acid substitutions (Arg1273Lys and Glu1293Lys; exon 27) were found in the girl and her father, localized in close proximity to the region that codes for the functionally critical second nucleotide-binding fold of ABCC6. Although a causal involvement of these amino acid substitutions could not be proven based on this study, both heterozygote substitutions may possibly have interacted with other undetected recessive maternal ABCC6 changes in the child. To the best of our knowledge, this is the first report of an association between early-onset PXE and severe Moya Moya syndrome possibly related to ABCC6 changes.

    Notes: This prospective, clinical trial evaluated the effects of short-term propofol administration on triglyceride levels and serum pancreatic enzymes in children undergoing sedation for magnetic resonance imaging. Laboratory parameters of 40 children, mean age (SD; range) 67 (66; 4–178) months undergoing short-term sedation were assessed before and 4 h after having received propofol. Mean (SD) propofol loading dose was 2.2 (1.1) mg.kg−1 followed by continuous propofol infusion of 6.9 (0.9) mg.kg−1.h−1. Serum lipase levels (p = 0.035) and serum triglyceride levels (p = 0.003) were raised significantly after propofol administration but remained within normal limits. No significant changes in serum pancreatic-amylase levels were seen (p = 0.127). In two (5%) children, pancreatic enzymes and in four (10%) children triglyceride levels were raised above normal limits; however, no child showed clinical symptoms of pancreatitis. We conclude that even short-term propofol administration with standard doses of propofol may have a significant effect on serum triglyceride and pancreatic enzyme levels in children.

    Notes: Abstract Extensive work on ethanol production with the Gram-negative bacterium Zymomonas mobilis has revealed that this is a promising microorganism for industrial use. Concise knowledge of the physiology and metabolism of this organism provides the basis for further improvements by genetic engineering and for the optimization of Zymomonas-specific fermentation processes.

    Notes: Abstract We carry out Monte Carlo simulations of the 4d SU(2) lattice gauge theory. The standard action and the Symanzik tree-improved action are used. Results for the string tension, glueball masses, and energy-momentum dispersion are reported. In case of the standard action our results are a finite size study extending previous investigations.

    Notes: Abstract Pyruvate decarboxylase (EC 4.1.1.1) from the ethanol producing bacterium Zymomonas mobilis was purified to homogeneity. This enzyme is an acidic protein with an isoelectric point of 4.87 and has an apparent molecular weight of 200,000±10,000. The enzyme showed a single band in sodium dodecylsulfate gel electrophoresis with a molecular weight of 56,500±4,000 which indicated that the enzyme consists of four probably identical subunits. The dissociation of the cofactors Mg2+ and thiamine pyrophosphate at pH 8.9 resulted in a total loss of enzyme activity which could be restored to 99.5% at pH 6.0 in the presence of both cofactors. For the apoenzyme the apparent K m values for Mg2+ and thiamine pyrophosphate were determined to be 24 μM and 1.28 μM. The apparent K m value for the substrate pyruvate was 0.4 mM. Antiserum prepared against this purified pyruvate decarboxylase failed to crossreact with cell extracts of the reportedly pyruvate decarboxylase positive bacteria Sarcina ventriculi, Erwinia amylovora, or Gluconobacter oxydans, or with cell extracts of Saccharomyces cerevisiae.

    Notes: Platelets from adolescents with minimal curve scoliosis (mcs) (7-18?) and healthy control subjects were examined for morphometry under the electron microscope and tested for calcium content and surface negative charge. These parameters have previously been found to be abnormal in severe idiopathic scoliosis (is) patients. Significantly more patients than control subjects showed deviations from normal in all tests. Two tests in particular, the average number of dense bodies per cell and an increased surface negative charge, were the most frequent abnormalities. In an attempt to assess the possibility of using platelet tests for prediction of curve progression, statistical comparisons were made and discriminant scores were generated for each patient. The results were compared with the clinical findings after a 2-to 3.5-year follow-up. The predictions proved to be incorrect although each of the five patients who had curve progression had some platelet abnormality. It is concluded that although platelet pathology does occur in early idiopathic scoliosis, it cannot be used as a prognostic indicator of curve progression.
