Abstract

International audience; The EuroDendro project aims to detect the signal of recent snow-avalanche activity within the analyses of tree rings. In mountain areas, even middle mountains, snow avalanches are a common process & pose serious hazards & risks in recently occupied sectors, either for residence or recreation purposes. Where (i) geomorphological evidence of snow-avalanche occurrence are scarce, (ii) historical records are poor & (iii) trees are colonizing part of the slopes, tree-ring analyses appear as a good alternative to reveal the recent snow-avalanche history. The dendromorphological approach consists in a survey of the investigated areas to inventory damages that affect the morphology of the tree: tilting of the trunk, presence of scars on the trunk, topped trees. Such a survey enables mapping the most frequent snow-avalanche paths, helping to: locate the maximum potential damages estimate the runout distances appreciate the lateral dispersion of the events The EuroDendro project is very interested in: (i) broad-leaved trees, which attracted seldom attention in dendrogeomorphology related to snow-avalanche activity: birch (Betula pubescens) in N Iceland birch (Betula pubescens) & alder (Alnus) in W Norway beech (Fagus sylvatica) in NE Cantal-France (ii) coniferous trees in little explored areas where broad-leaved trees are unavailable: spruce (Picea abies) in Central Romania Core extractions in c & d directions, i.e. parallel to the main flux lines, on both the uphill & the downhill sides of the tree Core analyses on a Lintab measurement table, enabling tree-rings counting, location & dating of growth disturbances (narrow & large rings) & reaction wood formation. The EuroDendro project investigates four main areas, some of them in connection with other scientific frameworks. The investigated areas are located in: xx (A) Northern Iceland, in the Dalsmynni valley, the Ljósavatn-skarð pass & the southern Fnjóskadalur valley, (B) Western Norway, at the bottom of Nordfjord, in Erdalen & Bødalen, (C) Central Romania, in the Southern Carpathians, in the Bâlea valley, Făgărăş massif, (D) Central France, in the Northeastern valleys of the Cantal massif. xx All these areas are characterised by steep slopes, harsh wintry conditions, known frequent snow-avalanche activity, a relative remotness & a tree-cover on talus & cones.

Abstract

Introduction: Olfactory disorders are among the four most common post-COVID-19 complaints. The aim of our prospective study from a university ENT post-COVID consultation (PCS) was to substantiate the symptoms with psychophysical test results., Methods: After an ENT examination, 60 post-COVID-19 patients (41 women) were asked in writing about their medical history. Their ability to smell was tested using the extended Sniffin' Sticks test battery and their ability to taste was determined using the 3-drop test. From these data, three quantitative olfactory (RD) and gustatory (SD) diagnoses could be defined from normal value tables. Every second patient took part in a control examination., Results: Up to the first examination, 60 patients reported smell and 51 taste disorders; their average duration was 11 months in both cases. Objectified pathologic RD and SD had 87% and 42% of the total cohort, respectively. Every third patient suffered from an objectified combination of olfactory and gustatory damage. About every second patient complained of parosmia. Parosmic patients with two visits came earlier for a check-up. Six months after the initial examination, the detection thresholds, the TDI and the RD had improved in these patients. The self-assessment of olfactory ability had not changed., Conclusions: Objectified pathologic RD persisted in our PCS for a mean of 1.5 years from the onset of infection. Parosmics had a better prognosis. For the healthcare system and especially for the patients affected, they continue to be a burden even after the pandemic., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Abstract

Introduction: Disorders of the sense of smell and taste are often complained as a long-COVID symptom. In a special long-COVID consultation (ENT-LCS), we wanted to figure out how large the proportion of pathological olfactory or gustatory diagnoses actually is in this cohort., Methods: 48 adult patients who visited the ENT-LCS because of their own suffering were asked about their history, rated their ability to smell (SER) and taste (SES) with school grades and completed the extended Sniffin' Sticks test and the 3-drop test as a taste test. Diagnoses were made from the SDI smell score and the total taste score using normative values. Correlations were calculated between the measured scores and the self-assessment and between SER and SES., Results: Pathological chemosensory diagnoses were present in 90%. Pathological olfactory diagnoses were twice as common as gustatory ones. No pathological diagnosis could be verified in 10% of the cohort. Anosmia-ageusia syndrome was diagnosed in six patients. SER correlated strongly with SDI. SES correlated moderately with SScore-total. SER correlated strongly with SES., Conclusions: There is a risk of smell-taste confusion when interpreting reported chemosensory symptoms. This is another reason why reference is made to the importance of quantifying the chemical senses with validated tests., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.
