Skin protection is a very important factor for the prevention of occupational skin disorders. Therefore, we evaluated a hand cream that was specially formulated for highly stressed skin with regard to its capability to reduce dry, rough, and scaly skin. The objective of this study was to conduct a controlled use test of a barrier repair cream containing pseudo-ceramide and demonstrate its efficacy for hairdressers with dry, sensitive hands and/or occupational skin disorders. A total of 30 hairdressers (29 females and 1 male, aged 20 - 67) participated in the study. All subjects suffered from dry hands. Subjects applied the test cream on their hands for 28 days (four weeks). For each subject, the skin surface topography of the hands was measured by the Surface Evaluation of Living Skin (SELS) system at day 14 (week 2) and day 28 (week 4). Dryness, scaling, cracking, redness, and itchiness were evaluated and graded by experts at week 2 and week 4, and then compared to baselines. All 30 subjects completed the study. A comparison of the changes from baseline to endpoint revealed a statistically significant reduction in skin roughness, scaling, and volume measured according to SELS. These data were confirmed by photographic documentation. The results were further supported by the expert evaluation. For the symptoms dryness and scaling, improvement could be observed in almost all regions of the hands. In addition, according to subjective assessments of overall hand skin condition and the hand cream, subjects reported clear improvement over time (p value below 0.001) and good efficacy of the product. In this study, the test hand cream showed excellent skin compatibility. Therefore, the hand cream may be effective for hairdressers with dry, sensitive hands and/or occupational skin disorders.展开更多

Furthermore, the day to day variability of gastric emptying for solids should be assessed. Methods 13 C octanoic breath tests were performed in 15 type 1 diabetic subjects on two separate days within one week. The influence of metabolic control on gastric emptying was prospectively examined over a mean of 8 months in 14 patients with newly diagnosed type 1 diabetes and 44 long term diabetic patients (type 1: n=31; type 2: n=13).Patients with longterm diabetes were stratified according to their HbA 1c at follow up (group 1: HbA 1c U7.5%, n=17; group 2 HbA 1c >7.5%, n=27). 13 C octanoic breath tests were sampled with an isotope selective non dispersive infrared spectrometer. The gastric emptying parameters were calculated using nonlinear regression analysis of the time course of 13 CO 2 exhalation:half emptying time (t 1/2 ) and lag phase (t lag ). Results The intraindividuell coefficient of variation was 17.8% for t 1/2 , and 28.2% for t lag . Mean t 1/2 and t lag in newly diagnosed type 1 diabetics were normal at baseline and were significantly increased at follow up. In patients with longterm diabetes, gastric emptying was unchanged during follow up. Gastric emptying was significant delayed in group 2 compared with group 1 at baseline and follow up respectively. There was a significant correlation between HbA 1c and t 1/2 , t lag at follow up. Conclusions 13 C octanoic breath test has a relatively good reproducibility in patients with type 1 diabetes. Gastric emptying times are already significantly increased after few months in newly diagnosed type 1 diabetes. There is a more pronounced delay of gastric emptying in longterm diabetic subjects with poor compared to patients with good metabolic control.展开更多
