    Notes: Summary Human immunodeficiency virus (HIV) infects and destroys crucial components of the immune system, leaving patients susceptible to a number of viral, bacterial and fungal diseases. Viral warts are caused by human papillomavirus infection and are a common skin disease that afflicts HIV-infected patients. Treatment modalities currently rely on destruction of the infected tissue or interruption of cell division; however, frequent recurrence is a particular challenge in HIV-infected patients. We report the case of a 41-year-old HIV-positive man with multiple common warts located on his hands and feet. Following 5 months of treatment with imiquimod, an immune response modifier, as a 5% cream, complete clearance of all warts was achieved. Mild erythma, itching and burning at the application site was observed in the early stages of treatment. The patient showed no relapse of warts at the 30-month follow-up visit.

    Notes: Amorphous rare-earth transition metal alloys of composition (Gd1−xFex)1−yAuy with x=0.74, 0.77, and 0≤y≤0.40 were prepared by evaporation onto rotating glass substrates. The magnetic and magneto-optic properties have been investigated in the temperature range 4.2≤T≤TC revealing a decrease of the compensation and Curie temperature, the uniaxial anisotropy, and the Faraday and Kerr rotation with increasing gold content. The temperature behavior can be interpreted in terms of a mean-field analysis indicating a pronounced influence of the gold on the iron moment and the exchange constants. The temperature dependence of the Faraday rotation can be described in terms of the sublattice magnetizations inferred from the fit of the mean-field theory to the measured saturation magnetization.

    Influence of preparation conditions on magnetic properties and aging behavior of rf diode sputtered GdTbCo films (1987)

    Notes: GdTbCo films were rf diode sputtered from a composite target varying the argon pressure PAr and the substrate bias voltage Vb. Both the uniaxial magnetic anisotropy constant Ku and the aging behavior of the films depend strongly on the preparation parameters. The absolute maximum of Ku was obtained at Vb=−150 V. However, at this bias voltage nearly the highest oxidation rate of unprotected 100-nm-thick films was observed. Films of highest stability are obtained without any bias voltage. The oxidation rate is correlated with the Ar concentration in the films. It was argued recently that the anisotropy of sputtered films could depend on argon incorporation. Our results seem to rule out this mechanism since GdTbCo films prepared at zero bias show a relative Ku maximum in dependence on PAr where the argon concentration is near its absolute minimum. The magneto-optic Kerr rotation θK of the films can only be correlated with the Co concentration for zero bias films. Some additional variation depending on the bias voltage has been observed.

    Notes: BACKGROUND: Pantoprazole is a proton pump inhibitor characterized by a low potential to interact with the cytochrome P450 enzyme system in man. Its effect on intragastric pH following single and repeated oral intake was investigated in comparison to omeprazole by continuous intragastric pH-metry at doses recommended for treatment of peptic ulcer disease. METHODS: Sixteen healthy male subjects underwent two dosing periods. From day 1 to day 7, they were given once daily by mouth 40 mg pantoprazole in one period and 20 mg omeprazole in the other period, according to a double-blind randomized crossover design. Twenty-four-hour intragastric pH was recorded and frequent blood samples for pharmacokinetic analysis were taken on day 1 and day 7. A placebo pH profile was obtained prior to each treatment period. RESULTS: Pantoprazole was significantly more effective than omeprazole with regard to increase in 24-h and daytime pH, following both single (median 24-h pH: 1.45 vs. 1.3, P 〈 0.05; median daytime pH: 1.6 vs. 1.3, P 〈 0.01) and repeated (median 24-h pH: 3.15 vs. 2.05, P 〈 0.01; median daytime pH: 3.8 vs. 2.65, P 〈 0.05) oral intake. As compared to the first dose, repeated administration of both drugs markedly increased the effect on intragastric pH. With pantoprazole, steady- state serum concentrations were obtained after the first dose, but not with omeprazole. Both drugs were well tolerated without relevant changes in vital signs of clinical laboratory parameters. CONCLUSION: Pantoprazole 40 mg is significantly more effective than omeprazole 20 mg in raising intragastric pH.

    Elevated expression of extracellular matrix metalloproteinase inducer (CD147) and membrane-type matrix metalloproteinases in venous leg ulcers (2002)

    Notes: Summary Background  Matrix metalloproteinases (MMPs) contribute to matrix remodelling in venous leg ulcers. Extracellular MMP inducer (EMMPRIN; CD147) has been reported to increase MMP expression, and membrane type 1 MMP (MT1-MMP) has been implicated in the activation of MMPs. Objectives  To examine whether and to what degree EMMPRIN, MMP-2, MT1-MMP and membrane type 2 MMP (MT2-MMP) are expressed in venous leg ulcers as well as the association with MMP activity. Methods  EMMPRIN, MMP-2, MT1-MMP and MT2-MMP were analysed by zymography and immunohistochemistry in biopsies from healthy skin and lesional tissue from venous leg ulcers. Results  Zymography provided direct evidence of increased proteolytic activity of MMP-2 in lesional skin in comparison with healthy controls. Immunostaining showed intense expression of EMMPRIN, MMP-2, MT1-MMP and MT2-MMP in dermal structures of venous leg ulcers, whereas only EMMPRIN and MMP-2 showed elevated expression in perivascular regions. Our findings indicate that venous leg ulcers are characterized by elevated expression of EMMPRIN, MMP-2, MT1-MMP and MT2-MMP. The immunohistological findings of skin alterations reflect the dynamic process of activation of soluble and membrane-bound MMPs, which may be highly induced by EMMPRIN. Conclusions  These data suggest for the first time that membrane-bound MMPs may favour enhanced turnover of the extracellular matrix and support unrestrained MMP activity in venous leg ulcers.

    Notes: Abstract. We investigate the degradation of ZnO/CdS/ Cu(In,Ga)Se2 heterojunction solar cells for space applications and the defect generation in polycrystalline Cu(In,Ga)Se2 thin films by irradiation with 1-MeV electrons with fluences φe up to φe=5×1018 cm-2. Notable degradation of the solar cell performance starts at fluences of φe=1017 cm-2 where the open circuit voltage decreases by about 5% while short circuit current and fill factor remain essentially unaffected. Thus, Cu(In,Ga)Se2 solar cells withstand electron fluences which are higher by one order of magnitude or more when compared to other technologies. A model describes the absolute open circuit voltage loss considering the increase of space charge recombination by electron irradiation-induced defects. Defect analysis by admittance spectroscopy shows that acceptor defects with an energy distance of approximately 300 meV from the valence band are generated at a rate γ=0.017 (±0.01) cm-1.

    Notes: Abstract. Stationary spectra offer information on the interplay between the structures and the nature of electronic excitations reflecting bonding properties, as shown by comparing Sin with Agn (n=4-6) clusters. In order to study the dynamical properties, simulations and analysis of femtosecond (fs) time-resolved pump–probe or pump–dump signals have been carried out, which allows us to determine the timescales and the nature of configurational changes versus internal vibrational relaxation (IVR) in electronic ground or excited states. For this purpose we have developed a multi-state ab initio molecular dynamics (involving ground as well as adiabatic or non-adiabatic excited electronic states) on the timescale of the nuclear motion, using the time evolution of a thermal ensemble in the Wigner representation. The combination of ab initio quantum-chemical methods used for the molecular dynamics ‘on the fly’ and the Wigner-distribution approach for the description of the motion of the nuclei also allowed the accurate determination of pump–probe and pump–dump signals under temperature-dependent initial conditions. We use this novel combination of methods to investigate the dynamics in excited states of non-stoichiometric NanFn-1 clusters with a single excess electron. The timescales of the structural relaxation in excited states versus intramolecular vibrational relaxation processes have been determined, as illustrated for the example of Na4F3. This is the first study of the system with 15 degrees of freedom for which the dynamics in the excited states has been carried out without the precalculation of the energy surfaces.

    Notes: Abstract Discussion of the total costs and cost-effectiveness ratios of patients receiving high-dose chemotherapy (HDC) and peripheral blood stem cell support (PBSCS) is controversial. In Germany, no reliable data are available, whereas in other countries this issue has been extensively studied. We performed a pharmacoeconomic evaluation on all patients (n = 37) treated with HDC and PBSCS at our institution between July 1994 and June 1997. Patients suffered from high-risk or poor-prognosis breast cancer (n = 24), Hodgkin's disease (n = 3), high-grade non-Hodgkin's lymphoma (n = 4), multiple myeloma (n = 2), small-cell cervical cancer (n = 1), malignant hystiocytosis (n = 1) and testicular cancer (n = 2). For pharmacoeconomic evaluation, the period from initiation of induction chemotherapy (IC) until reconstitution after the last course of HDC and PBSCS was considered. A total of 18 patients received IC/HDC/PBSCS for locally advanced or systemic disease, and 19 patients received adjuvant or consolidation IC/HDC/PBSCS. Treatment protocols were heterogeneous. Patients were treated with two to five courses (median two) respectively of IC and sequential mono-HDC (n = 26), tandem-HDC (n = 10) or triple-HDC (n = 1). All patients received granulocyte/macrophage-colony-stimulating factor (G-CSF) for stem cell mobilisation and for amelioration of neutropenia after HDC. The relative costs (based on supplier prices) for the total amount of drugs prescribed during the in-patient period was 29.8% for G-CSF, 35.8% for blood products 18.5% for chemotherapy, 2.4% for antiemetics, 5.9% for antimicrobial drugs and 7.6% for other drugs. Contrary to expectations, antimicrobial drugs had only a minor pharmacoeconomic impact during IC/HDC/PBSCS in patients with high-risk or poor-prognosis malignancies, indicating that prolonged septic complications were uncommon in our institution. We conclude that pharmacoeconomic evaluations in IC/HDC/PBSCS might be integrated into the effort to ensure quality control and monitoring.

    Description / Table of Contents: Summary Hashimoto's encephalopathy is a steroid-responsive, relapsing or progressive encephalopathy associated with Hashimoto's thyroiditis. Characteristic clinical features are confusion, seizures, alteration in conscious level, stroke-like episodes, myoclonus, and tremulousness. High CSF protein levels without pleocytosis and a diffusely abnormal EEG are typical findings. Brain CT and MRI and cerebral angiogram are usually normal. We present two case reports of Hashimoto's encephalopathy in 55- and 77-year-old patients who both responded well to steroid therapy, and review the literature.
    Notes: Zusammenfassung Als Hashimoto-Enzephalopathie wird eine steroid-sensitive, schubförmig oder stetig progrediente Enzephalopathie bezeichnet, welche mit einer Hashimoto-Thyreoiditis assoziiert ist. Charakteristische klinische Befunde sind Verwirrtheit, epileptische Anfälle, Vigilanzminderung, schlaganfallähnliche Episoden, Myoklonien und Tremor. Die Liquordiagnostik zeigt meist eine Proteinerhöhung ohne Pleozytose, das EEG generalisierte und umschriebene Verlangsamungen, seltener triphasische Wellen und epilepsietypische Potentiale; die zerebrale Bildgebung mittels CT oder MRT sowie die zerebrale Angiographie sind in der Regel normal. Wir stellen 2 Patientinnen im Alter von 55 und 77 Jahren vor, bei denen die Symptome einer Hashimoto-Enzephalopathie gut auf eine Behandlung mit Steroiden ansprachen, und geben einen Überblick über die Literatur.
