    Treatment of periocular wrinkles with topical nifedipine

    The appearance of facial expression wrinkles is the result of chronic contraction of mimic muscles. Nifedipine is a dihydropyridinic calcium antagonist which blocks muscular cells' calcium channels, therefore inhibiting their contraction. We assumed that topical nifedipine was able to relax mimic muscular fibres in the same way, thus reducing the depth of wrinkles. We performed a clinical and experimental study, enrolling 64 female patients with periocular wrinkles. They applied a cream containing 0.5% nifedipine (Antrox; Bracco, Milan, Italy) once daily for 90 days. The length and depth of wrinkles (measured by a digital profilometer), moisturizing of periocular skin (measured by a corneometer), and trans-epidermal water loss (TEWL; measured by a tewameter), were evaluated. All parameters were measured before the beginning of treatment, and 45 and 90 days later. At the end of the study, topical nifedipine proved statistically effective in reducing the depth of wrinkles. No significant differences in the length of wrinkles were recorded. No significant changes were observed in moisturizing. TEWL gradually improved, although without statistical significance. On the basis of the results of this study, 0.5% nifedipine cream seems to be effective in reducing the depth of periocular wrinkles. Other studies are necessary in order to confirm these results

    AIM: To investigate in symptomatic uncomplicated diverticular disease the efficacy of symbiotics associated with a high-fibre diet on abdominal symptoms. METHODS: This study was a multicentre, 6-mo randomized, controlled, parallel-group intervention with a preceding 4-wk washout period. Consecutive outpatients with symptomatic uncomplicated diverticular disease, aged 40-80 years, evaluated in 4 Gastroenterology Units, were enrolled. Symptomatic uncomplicated diverticular disease patients were randomized to two treatment arms A or B. Treatment A (n = 24 patients) received 1 symbiotic sachet Flortec (c) (Lactobacillus paracasei 821060) once daily plus high-fibre diet for 6 mo. Treatment B (n = 21 patients) received high-fibre diet alone for 6 mo. The primary endpoint was regression of abdominal symptoms and change of symptom severity after 3 and 6 mo of treatment. RESULTS: In group A, the proportion of patients with abdominal pain 24 h decreased from 60% to 20% then 5% after 3 and 6 mo, respectively in group A (P < 0.001) and from 33.3% to 9.5% at both 3 and 6 mo in group B (P = 0.03). In group A the proportion of patients with abdominal bloating significantly decreased from 95% to 60% after 3 mo, and remained stable (65%) at 6-mo follow-up (P = 0.005) while in group B, no significant changes in abdominal bloating was observed (P = 0.11). After 6 mo of treatment, the mean visual analogic scale (VAS) values of both short-lasting abdominal pain (VAS, mean SD, group A: 4.6 +/- 2.1 vs 2.2 +/- 0.8, P = 0.02; group B: 4.6 +/- 2.9 vs 2.0 +/- 1.9, P = 0.03) and abdominal bloating (VAS, mean SD, group A: 5.3 +/- 2.2 vs 3.0 +/- 1.7, P = 0.005; group B: 5.3 +/- 3.2 vs 2.3 +/- 1.9, P = 0.006) decreased in both groups, whilst the VAS values of prolonged abdominal pain decreased in the Flortec group, but remained unchanged in the high-fibre diet group (VAS, mean +/- SD, group A: 6.5 +/- 1.5 vs 4.5 +/- 2.1, P = 0.052; group B: 4.5 +/- 3.8 vs 5.5 +/- 3.5). CONCLUSION: A high-fibre diet is effective in relieving abdominal symptoms in symptomatic uncomplicated diverticular disease. This treatment may be implemented by combining the high-fibre diet with Flortec (c). (C) 2012 Baishideng. All rights reserved

    Stratigraphical and micropaleontological data on the tertiary of Southern Piemont (Northern Italy)

    During the years 1959-1963 stratigraphical investigations were carried out in Southern Piemont (Northern Italy) along five traverses, taken at right angles to the strike of the strata, which range in age from Eocene to Pliocene. These sections are important in that they include the rype sections of some Neogene stages (Langhian, Serravallian and Tortonian) and some classical localities, such as Moliere and Costa Lupara. The sequences of these sections (numbered I-V) show large discrepancies in lithology as well as in the thickness between the corresponding units. To avoid confusion a number of formations and members are introduced for each of the sections. Parts of the sections are barren but in most portions numerous planktonic foraminifera were found. They could be used to establish ten biozones, successively I: the semi-involuta Zone, II: the cerro-azulensis Zone, III: the Globigerina Zone, IV: the Globigerinoides-Globoquadrina Zone, V: the Globorotalia Zone, VI: the bisphericus Zone, VII: the Orbulina Zone, VIII: the menardii Zone, IX: the nepenthes Zone, and X: the obliquus Zone. In addition some of the larger Foraminifera were investigated in more detail, in particular the Nephrolepidina and Miogypsina species. The embryonic-nepionic apparatus of Lepidocyclina praemarginata and Lepidocyclina morgani were compared on a biometric basis. Only a part of the phylogenetic series of the Miogypsinidae was encountered, namely from M. gunteri to M. intermedia. Correlation by means of the zonation with these larger and planktonic Foraminifera leads to interesting stratigraphic results. 1. In the correlation of the sections II, III and IV only slight differences with the Italian Geological Map have been met with, but in the sections I and V there are large deviations from this map. 2. The type Langhian appears to begin closely above the Orbulina surface. For the assumed chronological interval between Helvetian and Tortonian the author suggests to use the term Serravallian rather than Langhian, because the latter has commonly been erroneously considered to be the equivalent of the Burdigalian. The limits between the successive stages Burdigalian, Helvetian, Serravallian and Tortonian can be correlated with biozones of planktonic Foraminifera. 3. Furthermore it was found that the beginnings of the genera Globigerinoides and Globoquadrina do not coincide with the Oligocene-Miocene boundary. Both genera start their range in the Late Oligocene already. 4. Among the general conclusions of a paleogeographic nature we may note, that the transgression over the metamorphic basement of the Massif of Voltri and Ligurian Alps advanced in westward direction during Rupelian and probably Chattian times. 5. In the most eastern section (Tortona-Garbagna area) the Miocene sequence is not complete, as sediments, corresponding to at least two of the biozones are lacking here
