Intrathoracic solitary fibrous tumor - an international multicenter study on clinical outcome and novel circulating biomarkers
Intrathoracic solitary fibrous tumor (SFT) is a rare disease. Radical resection is the standard of care. However, estimating prognosis and planning follow-up and treatment strategies remains challenging. Data were retrospectively collected by five international centers to explore outcome and biomarkers for predicting event-free-survival (EFS). 125 histological proven SFT patients (74 female; 59.2%; 104 benign; 83.2%) were analyzed. The one-, three-, five- and ten-year EFS after curative-intent surgery was 98%, 90%, 77% and 67%, respectively. Patients age (>/=59 vs. 10 cm vs. 5 vs. < 5 HR 3.91, CI 1.40-10.89, p = 0.009) were prognostic after univariate analyses. After multivariate analyses tumor-dignity and fibrinogen remained as independent prognosticators. Besides validating the role of age, tumor-dignity, tumor-size, stage and resection margins, we identified for the first time inflammatory markers as prognosticators in SFT
Ethnobotanical remarks on Central and Southern Italy
<p>Abstract</p> <p>Background</p> <p>The present paper is a brief survey on the ethnobotanical works published by the Authors since 1981, concerning the research carried out in some southern and central Italian regions. Before Roman domination these territories were first inhabited by local people, while the southern areas were colonized by the Greeks. These different cultural contributions left certain traces, both in the toponyms and in the vernacular names of the plants and, more generally, in the culture as a whole.</p> <p>Methods</p> <p>Field data were collected through open interviews, mainly of farmers, shepherds and elderly people, born or living in these areas for a long time. Voucher specimens of collected plants are preserved in the respective herbaria of the Authors and in the herbarium of "Roma Tre" University. Important contributions have been made by several students native to the areas under consideration. A comparative analysis with local specific ethnobotanical literature was carried out.</p> <p>Results</p> <p>The paper reports several examples concerning human and veterinary popular medicine and in addition some anti-parasitic, nutraceutic, dye and miscellaneous uses are also described. Moreover vernacular names and toponyms are cited. Eight regions of central and southern Italy (particularly Latium, Abruzzo, Marche and Basilicata) were investigated and the data obtained are presented in 32 papers. Most of the species of ethnobotanical interest have been listed in Latium (368 species), Marche (274) and Abruzzo (203). The paper also highlights particularly interesting aspects or uses not previously described in the specific ethnobotanical literature.</p> <p>Conclusion</p> <p>Phyto-therapy in central and southern Italy is nowadays practised by a few elderly people who resort to medicinal plants only for mild complaints (on the contrary food uses are still commonly practised). Nowadays therapeutic uses, unlike in the past, are less closely or not at all linked to ritual aspects. Several plants deserve to be taken into consideration not only from the anthropological or cultural point of view, but also for further phyto-chemical investigation. Our studies, as well as those of other authors, try to provide an original picture of the local ethno-biodiversity.</p

Transverse Facial Artery Perforators: Anatomical, Two- and Three-Dimensional Radiographic Study
BACKGROUND: Increased anatomical knowledge of skin vascularization, such as the recent description of angiosome and perforasome concepts, has led to important innovations in flap surgery. In this sense, few studies have been performed on face vascularization especially for facial artery perforasomes. The aim of this study was to analyze the number, size, and localization of transverse facial artery perforators and their perfusion area. METHODS: Fourteen hemifaces of fresh adult cadavers from the Department of Anatomy of Lyon University were harvested. Transverse facial artery perforators were identified, dissected, cannulated, and selectively injected with 1 ml of patent blue or contrast solution. Photography, microangiography, and computed tomography were performed. Perforator diameter and localization from the lateral canthus were measured. Exact topography and size of the perforasome were analyzed. RESULTS: Twenty-three transverse facial artery perforators were identified. Mean perforator diameter was 1.01 +/- 0.3 mm. Mean perforating site was 31.0 +/- 8.0 mm lateral to and 38.7 +/- 8.8 mm below the lateral canthus. Mean single perforasome surface area was 25.3 +/- 18.34 cm and mean transverse facial artery skin territory was 40.5 +/- 9.78 cm. CONCLUSIONS: The transverse facial artery provides at least one perforator that can be accurately localized using a Doppler probe. Clinical applications related to the improved knowledge of transverse facial artery perforators could be as follows: (1) performing a lateral facial skin flap; (2) facial composite allotransplants; (3) face-lift procedures to improve skin perfusion; and (4) prevention of vessel injury in aesthetic procedures such as dermal filler injection or thread-lift techniques
Antinociceptive activity of methanolic extract of leaves of <i style="">Achyranthes aspera</i> Linn. <i style="">(</i>Amaranthaceae) in animal models of nociception
817-821Antinociceptive activity of methanolic extract of leaves of A. aspera was studied by peripheral/non-narcotic model of
nociception like acetic acid induced writhing syndrome test and central/narcotic
models like hot plate and tail flick tests. The methanolic extract of the
plant, administered orally (@ 300, 600 and 900 mg/kg, body weight) and the
standard drug (piroxicam; 10 mg/kg body weight, po) produced significant
analgesic activity in acetic acid induced writhing syndrome as compared to the
vehicle treated control group. In the hot plate analgesic test, in A. aspera at the above doses and the
standard drug treated group (morphine sulphate @ 1.5 mg/kg, ip), the duration
of reaction time (sec) increased dose dependently and significantly compared to
the control group. In the tail flick test, the
plant extract produced dose dependant increase in reaction time which was
significantly higher in the test and standard group compared to the control
group. The plant possesses significant antinociceptive property as evidenced in
all the animal models of nociception. It might possibly exert its effect
through diverse mechanism that may involve both central and peripheral
pathways. The preliminary phytochemical investigation revealed the presence of
steroids, alkaloids and triterpene in the methanolic extract of leaves of A. aspera which may be responsible for
its antinociceptive activity
Preliminary studies on local anesthetic and antipyretic activities of Spilanthes acmella Murr. in experimental animal models
Objective: Spilanthes acmella Murr. (Family: Compositae) is a herb that
grows throughout the tropics. It is used in the treatment of
rheumatism, fever, sore throat, and hemorrhoids. A tincture of the
flowers is used to relieve toothache. The leaves and flowers produce
numbness of the tongue when eaten as salad. The present study was
undertaken to evaluate the local anesthetic and antipyretic activities
of S. acmella in experimental animal models. Materials and Methods :
Aqueous extract of S. acmella Murr. (SAM) was tested for local
anesthetic action by (i) intracutaneous wheal in guinea pigs and (ii)
plexus anesthesia in frogs. In both the models, 2% xylocaine was used
as the standard drug. The anti-pyretic activity was determined by
yeast-induced pyrexia in rats. Aspirin 300 mg/kg was used as the
standard drug. Result : The test drug in concentrations of 10% and 20%
produced 70.36% and 87.02% anesthesia respectively by the
intracutaneous wheal compared to 97.22% anesthetic effect produced by
2% xylocaine (P<0.001). The mean onset of anesthesia with the test
drug was 5.33±0.57 min compared to 2.75±0.31 min (P<0.001)
for the standard drug in the plexus anesthesia model. In the
anti-pyretic model, ASA in doses of 100, 200, and 400 mg produced
dose-dependent reduction in mean temperature at various hours of
observation. Conclusion : The present study shows that SAM has
significant local anesthetic and antipyretic activities
