Herpes simplex (HSV) and varicella-zoster (VZV) skin infections share so many histological similarities that distinguishing between them may prove to be impossible. We developed and characterized a new monoclonal antibody, VL8, IgG kappa isotype, directed to the VZV envelope glycoprotein gpI. Immunohistochemistry with VL8 appeared highly sensitive and specific on formalin-fixed paraffin-embedded biopsies and a clear-cut distinction between HSV and VZV infections was possible. The pattern of VL8 immunolabelling in VZV infections was strikingly different from that found in HSV infections studied with polyclonal antibodies to HSV I and II. Double immunolabelling revealed the VL8 positivity of sebaceous cells, endothelial cells, Mac 387-and CD68-positive monocyte-macrophages, and factor XIIIa-positive perivascular, perineural and interstitial dendrocytes. Intracytoplasmic VL8 labelling of endothelial cells and perivascular dendrocytes was found at the site of leukocytoclastic vasculitis. [less ▲]

Background. New azoles have been successfully used as treatment of invasive aspergillosis. The purpose of this study was to compare the in vitro activity of posaconazole (Posa) with that of amphotericin B (AmB), itraconazole (Itra) and voriconazole (Vor) against A. fumigatus isolates according to NCCLS method (M38-P), and to compare visual and spectrophotometric readings for MIC determination. Methods. A total of 106 A. fumigatus isolates were selected as follows: 88 clinical isolates from colonized patients, 18 from patients with invasive aspergillosis and 7 environmental isolates. Their in vitro susceptibility was evaluated by the NCCLS microdilution method (M38-P) in RPMI 1640 medium. Determination of results was made by visual and spectrophotometric readings (630 nm) after 48 hours incubation at 35 degreesC. Three A. fumigatus reference strains (IHEM 5734, 6149 and 13935) were included as control. Results. 1. Geometric mean MICs/MIC90 (microg/ml) obtained by visual reading were respectively 0.66/1 (AmB), 0.37/0.5 (Itra), 0.27/0.5 (Vor) and 0.02/0.03 (Posa). 2. MIC values were comparable by spectrophotometric and by visual readings for all antifungal agents tested (p>.05) and did not depend on the isolates origin (p>.05). 3. Posaconazole had the lowest MICs (p< 0.001). 4. The itraconazole-resistant reference strain did not give cross resistance with voriconazole and posaconazole. CONCLUSIONS: Among azoles, posaconazole had a better in vitro activity against A. fumigatus than did voriconazole or itraconazole. Spectrophotometric reading could replace the less standardized visual reading for NCCLS microdilution method and MIC values obtained were comparable among all A. fumigatus isolates. [less ▲]

OBJECTIVE: To assess the contraceptive reliability, cycle control and tolerance of a new monophasic oral contraceptive (Yasmin) containing 30 microg ethinylestradiol and 3 mg drospirenone and compare it with a preparation containing an equal dose of ethinylestradiol combined with 150 microg desogestrel (Marvelon). METHODS: A multicenter, open-label, randomized study was carried out in 26 European centers. Contraceptive efficacy, cycle control and tolerance (including body weight, blood pressure and heart rate) were assessed over 26 cycles, plus a 3-month follow-up period. RESULTS: Of 900 women who were randomized, 887 started treatment and 627 completed the 26 cycles plus follow-up (310 in the ethinylestradiol/drospirenone group and 317 in the ethinylestradiol/desogestrel group). Both study preparations were found to be effective with regard to contraceptive reliability and cycle control was good. There were six pregnancies (three in each group), but none were considered to have been the result of method failures. The subjective and objective tolerances were good in both groups. A statistically significant difference was found in body weight changes between the two groups. While there was an increase in mean body weight in the ethinylestradiol/desogestrel group from cycle 5 onward, the mean body weight per cycle in the ethinylestradiol/drospirenone group was slightly below the baseline value throughout the study. The incidence ofpremenstrual symptoms was higher in the ethinylestradiol/drospirenone group than in the ethinylestradiol/desogestrel group during the 6 months prior to the study, but lower during treatment. The rates ofdysmenorrhea were identical under both treatments but the symptoms were more often mild and less often severe in the ethinylestradiol/drospirenone group. CONCLUSION: The combination of 30 microg ethinylestradiol combined with 3 mg drospirenone provides effective oral contraception and good cycle control, and is well tolerated. Ethinylestradiol/drospirenone had a more favorable effect on body weight than ethinylestradiol/desogestrel, with the mean body weight remaining lower than baseline for the majority of the women.

To evaluate the relative long-term improvement in coronary artery hemodynamics after revascularization by coronary artery bypass graft surgery (CABG) or percutaneous transluminal coronary angioplasty (PTCA), regional coronary flow reserve (CFR) was measured, by digital computer analysis of 35 mm cine film, in 50 men undergoing cardiac catheterization. CFR (mean +/- SEM) in 12 atherosclerotic arteries before revascularization was 1.02 +/- 0.05. Mean CFR in 29 normal arteries of men with normal coronary arteriograms was significantly higher (2.59 +/- 0.11) than that in 16 atherosclerotic arteries of patients revascularized by CABG (2.02 +/- 0.17, p less than .01) or in 14 atherosclerotic arteries of those revascularized by PTCA (1.97 +/- 0.12, p less than .01). No difference in CFR between the CABG and PTCA groups was found and variables known to influence CFR were similar between groups. Equivalent and significant long-term improvement in coronary artery hemodynamics is provided by CABG or PTCA. We postulate that the difference in CFR in the men with normal arteries and those who underwent revascularization was related to the effects of the general atherosclerotic process, which remain despite successful treatment by these techniques.

Organs responsible for equilibrium of cephalopods, the statocysts, possess numerous similarities with the vestibular systems of vertebrates. The statocysts are embebbed in the cephalic cartilage protecting the brain. Although statocysts have been largely described, few studies focused on the cephalic cartilage and its morphology. The aim of this study is to describe the morphology of both statocysts and cartilage, to compare them between different species and to determine which are the parameters influencing their morphology. For species of Decapodiformes (Sepia officinalis, Sepiola rondeletii, Loligo vulgaris and Illex coindetii) and two species of Octopodiformes (Octopus vulgaris and Eledone cirrhosa) have been studied. Cephalic cartilages from these species have been scanned by magnetic resonance imaging (MRI) and volumes and linear measurements have been taken on the 3 dimension reconstructed models of the cartilages and statocysts. Results show that Octopodiformes possess a globular cartilage which surrounds almost totally the brain. On the other hand Decapodiformes posses a cartilage with bigger lateral and anterior foramens and then surrounds a smaller part of the brain. The morphology of the statocysts also varies between the two superorders. The statocysts of Octopodiformes are divided into two parts: endolymph and perilymph while those of Decapodiformes aren’t. These morphological variations between the two groups might be related to their ecology. Eledone cirrhosa and Octopus vulgaris are typically benthic species and then might receive shocks more often than Decapodiformes that possess a more pelagic lifestyle. Octopodiformes might then need a better protection for their brain than Decapodiformes. [less ▲]

Computerized image analysis was used to compare lentigines (brown freckle-like cutaneous spots) induced by treatment with psoralens and ultraviolet light A (PUVA-induced lentigines) with those induced by solar exposure (actinic lentigines). For these conditions, which appear to be distinctive clinically and histologically, the number, size and shape of the macules were analyzed, revealing significant differences in the two latter parameters. This indicates that UV irradiations of different wave lengths act differently on melanocytes and/or on the interrelation between melanocytes and keratinocytes. The overall effect is much more self-limited in PUVA lentigines than in actinic lentigines, suggesting that the pathophysiology of these lesions is probably different. [less ▲]
