    Summary Background Numerous therapeutic schemes recommend topical administration of emollients immediately prior to ultraviolet (UV) B therapy. The rationale behind the clinical improvement is a presumed enhancement of UV transmission through the epidermis. Originating from this clinical observation, there has been some concern as to whether a well-hydrated skin in general might be more susceptible to actinic damage. Objectives To investigate whether rehydration of healthy skin causes an altered UVB sensitivity in vivo. Methods We determined minimal erythema doses (MEDs) and erythema sum scores (ESSs) after differential rehydration of the skin in 10 healthy volunteers. In each subject six UVB phototests were performed after pretreatment with five different emulsifying ointments (unguentum emulsificans and dilutions with 30, 50, 70 and 90% aqua purificans) plus a negative control. In vivo evaluation of stratum corneum hydration was performed by measurement of electrical capacitance. Results The results of this randomized, double-blind in vivo study indicated that rehydration of normal stratum corneum with the emulsifying ointments tested did not result in a significantly altered sensitivity to the erythematous effects of UVB irradiation (no significant differences in MED and ESS). Furthermore, there was no correlation between measured stratum corneum hydration and the erythema response of healthy skin. Conclusions Although many schemes recommend the administration of emollients prior to UV therapy, there have also been calls for caution, as an uncritical application may interfere with such treatment. We showed that the emulsifying ointments tested exhibited no photoprotective potential and thus are suitable for the pretreatment of psoriasis prior to phototherapy. It has long been discussed whether the effects of emollient pretreatment on response to UV occur only in psoriatic skin or also in healthy skin. Our results indicated that stratum corneum rehydration did not result in a significantly increased erythema response of healthy skin to UVB exposure. With regard to the use of rehydrating cosmetics in everyday life, the outcome of our pilot study is reassuring, as we could not confirm with our experimental design that well-hydrated healthy skin is more prone to actinic damage.

    Abstract We have measured distributions in transverse momentum and rapidity of protons from interactions of 14.6 GeV/nucleon28Si projectiles with targets of Al and Pb. The transverse momentum spectra exhibit a thermal shape with a rapidity dependent temperature parameter. For very central or violent collisions the proton rapidity distributions exhibit the large rapidity shifts and (for Si+Al) a peak at midrapidity as required for full stopping.

    Abstract Transverse energy distributions have been measured for collisions of 10 GeV/nucleon Si with targets of Al, Cu and Pb using a combination of a NaI wall and a uranium based sampling calorimeter. The measured cross sectionsdσ/dE T anddE T /dη are consistent with full stopping and an increase, with increasing values ofE T , of energy flow into large angles.

    Summary From February to November 1981 the diagnostic relevance of ultrasound (US), computed tomography (CT) and endoscopic retrograde cholangiopancreatography (ERCP) was compared prospectively in 75 patients with suspected pancreatic disease. Final diagnosis was confirmed by autopsy, surgery, clinical course, and further laboratory data. Thus it was possible to exclude pancreatic disorders in 32 patients. By ERCP we diagnosed all tumors; sensitivity was 100%. Sensitivity of US and CT were 63% each. In five cases US made the false positive diagnosis” pancreatic malignant tumor” (specifity 93%), CT and ERCP in two cases (specifity 97% each). In chronic pancreatitis specifity of US and ERCP were 100% and specifity of CT was 98%. Sensitivity of ERCP amounted to 93%, CT and US revealed 74% and 52%, respectively. We conclude that ERCP is the best morphologic diagnostic tool in differentiating chronic pancreatitis from pancreatic carcinoma. US is a good screening method and CT reveals good diagnostic results in acute pancreatitis.

    Summary The recently introduced Connected-Moments Expansion (CMX) is compared to a variational Lanczos scheme for estimating ground-state energies of many-body systems. A systematic approach is given for three quantum-mechanical systems: harmonic oscillator, anharmonic oscillator and the Kondo model. A second-order analysis is given in terms of particular ratios of moments of the Hamiltonian.
