    Abstract. Three unifloral honeys were identified by the pronounced presence of specific compounds by means of sensorial analysis and SPME-GC-MS. Smoky and resinous ('propolis') odors characterized unifloral "quillay" (Quillaja saponaria) honey. "Corontillo" (Escallonia pulverulenta) honey was characterized by caramel and vanillin aromas, and "ulmo" (Eucryphia cordifolia) honey by having an anise scent with a floral jasmine note. Safranal was a useful marker for "corontillo" honey. Isophorone and cetoisophorone were the distinctive compounds of unifloral "ulmo" honey. In "quillay" honeys, megastigmatrienone, 2-p-hydroxyphenylalcohol and minor quantities of β-pinene and linalool oxide were correlated with their sensory properties such as resinous. Key words: : Ulmo honey, Escallonia or "corontillo" honey, Quillaja honey, SPME-GC-MS analysis. Resumen. Tres mieles monoflorales se identificaron por la presencia notable de compuestos específicos usando análisis sensorial y SPME-GC-MS. Los olores a humo y a resina (o a propóleos) tipificaron la miel de quillay (Quillaja saponaria). La miel de corontillo (Escallonia pulverulenta) se caracterizó por sus aromas a caramelo y a vainilla, y la miel de ulmo (Eucryphia cordifolia) por su fragancia anisada con una nota floral de jazmin. Safranal constituyó un marcador útil para la miel de corontillo, mientras que isoforona y cetoisoforona fueron los compuestos distintivos de la miel monofloral de ulmo. En las mieles de quillay se correlacionaron megastigmatrienona, 2-p-hidroxifenilalcohol y las trazas de β-pineno y óxido de linalool con sus propiedades organolépticas tales como resinosa. Palabras clave: miel de ulmo, miel de corontillo o de Escallonia, miel de Quillaja, análisis SPME-GC-MS

    Expression of the human erythrocyte glucose transporter Glut1 in cutaneous neoplasia

    Background: The increased glucose uptake seen in cancer cells correlates with the expression of human erythrocyte glucose transporter (Glut1) protein in certain human malignancies. Objective: Our purpose was to determine Glut1 expression in cutaneous neoplasms. Methods: A polyclonal anti-Glut1 antibody (MYM) and a standard ABC immunoperoxidase technique were used to determine Glut1 expression in invasive squamous cell carcinomas (SCCs), SCC in situ, basal cell carcinomas (BCCs), melanomas, actinic keratoses (AKs), seborrheic keratoses, common acquired nevi, and scars with regenerative epidermal hyperplasia. Results: All of the cases of SCC in situ, 14 of 15 (93%) of the SCC, and 13 of 15 AKs (87%) showed intense membranous staining for Glut1. Glut1 staining was present in the epidermis of 8 of 15 scars (53%) but was not detected in any BCC, even in areas of focal keratinization and squamous metaplasia. Glut1 reactivity was absent in the melanomas and seborrheic keratoses. Conclusion: Glut1 expression in a cutaneous lesion strongly suggests a proliferative lesion of the squamous cell type

    Carotid artery web and ischemic stroke: A case-control study

    Objective: To determine whether there is an association between carotid artery web and ischemic stroke. Methods: This was a single-center, age- and sex-matched, case-control study. Cases were consecutive patients with anterior circulation ischemic stroke of undetermined etiology (Trial of Org 10172 in Acute Stroke Treatment [TOAST] classification). Controls were consecutive patients with cerebral aneurysms, arteriovenous malformations, or primary intracerebral hemorrhages. Additional inclusion criteria were age <60 years and CT angiography of the neck. Two neuroradiologists diagnosed webs according to previously published criteria. One neuroradiologist also assessed for nonstenotic atherosclerotic plaque (carotid wall thickness ≥3 mm or intramural calcification). We used conditional logistic regression to estimate the odds ratio between carotid web and ischemic stroke and its 95% confidence interval. Results: Fifty-three of 62 cases (85%) were matched by age (within 1 year) and by sex to 102 controls. There was a carotid web in 4 of 53 cases (9.4%) vs 1 of 102 controls (1.0%, odds ratio = 8.0, 95% confidence interval = 1.2-67, p = 0.032). There was no significant difference in the prevalence of nonstenotic carotid atherosclerotic plaque between the case and control groups. There was agreement on diagnosis of web for 163 of 164 patients (99%) and 7 of 8 webs (88%), and the Cohen for interobserver agreement was 0.93. Conclusions: There is an association between carotid artery web and ischemic stroke in patients who lack an alternative cause of stroke. Carotid web may be an underappreciated risk factor for stroke

    First detection of sarcoptic mange in free-ranging wild boar (Sus scrofa) in Switzerland

    In Switzerland sarcoptic mange is frequent in free-ranging wild carnivores but until recent years no cases had been recorded in wild ungulates. Since 2010, cases have been observed in wild boar in the cantons of Solothurn, Tessin and Thurgau. Here, we report the detection of mange-like skin lesions in wild boars by photo-trapping and the post-mortem findings in 6 culled animals presenting different stages of the disease. Potential sources of infection include mangy red foxes, outdoor domestic pigs and wild boars from surrounding countries. Disease spread in the wild boar population may become relevant not only for wildlife but also for domestic pig health in the future if piggeries' biosecurity is insufficient to prevent interactions with wild boar
