Kaposi's Varicelliform Eruption: A Potentially Life-Threatening Complication of Atopic Dermatitis.

Introduction: Kaposi's varicelliform eruption (KVE), also known as eczema herpeticum or eczema vaccinatum, is an acute dermatosis that affects patients with chronic dermatopathies. The diagnosis is primarily clinical and is characterised by the presence of a vesicular exanthema on physical examination. The exanthema subsequently evolves into crusted lesions with typical circular ulcerations in 'punched-out' areas on the skin affected by the underlying dermatopathy. Case description: We present the case of a 6-year-old patient who presented to the Paediatric Emergency department with skin lesions consistent with eczema herpeticum. The patient's management was initially outpatient; however, due to the slow progression of the condition, hospitalisation and intravenous antiviral treatment were initiated. Discussion: KVE affects patients with chronic dermatoses, especially atopic dermatitis. It is important to know the clinical presentation for an early suspicion. KVE is a medical emergency that requires prompt diagnosis and treatment. It can progress to secondary viraemia, which can be fatal in up to 10% of immunocompetent individuals and up to 50% of immunocompromised individuals. It is important to be aware of this condition and to start early treatment with antivirals, especially given the high prevalence of atopic dermatitis in our population. This condition is one of the most serious complications that can occur in these patients. LEARNING POINTS: To facilitate early suspicion and diagnosis, disseminate information about eczema vaccinatum.Emphasise the importance of initiating antiviral treatment early to prevent potential complications of eczema herpeticum.If left untreated, Kaposi's varicelliform eruption can result in up to a 10% mortality rate in immunocompetent individuals and a 50% mortality rate in those who are immunocompromised.

Influence of Oxygen Management on Color and Phenolics of Red Wines.

Winemaking involves contact at different stages with atmospheric oxygen, the consumption of which determines its final properties. The chemical analysis of red wines subjected to consecutive cycles of air saturation has been extensively researched; however, the capacity to consume different doses of oxygen before bottling is an aspect that has been little studied. In this work, the effect of saturation of different levels of oxygen on the final characteristics of different wines made from Tempranillo and Garnacha grape extracts was studied. For this purpose, the wines were subjected to controlled oxygen saturation levels to simulate their possible oxygenation before bottling. The only difference was the phenolic composition of grape extracts that were reconstituted under the same conditions to avoid the interferences inherent to the fermentation process and the additives added in the winery. The kinetics of oxygen consumption was then evaluated and its effect on the color, antioxidant capacity, and phenols of three different wines was analyzed. This work shows the relationship between the oxidation state of wine and changes in its chemical composition. In addition, it provides insight into the effect of oxygen consumption before bottling on the properties of wines subjected to high and single doses of oxygen.

New System for Simultaneous Measurement of Oxygen Consumption and Changes in Wine Color.

The design, construction and validation of a device for the accurate measurement of the dissolved oxygen content in wine and simultaneously the variation of its spectral fingerprint is presented. The novelty of this system is due to two innovative approaches. First, robustness in measurements is obtained by using cuvettes designed to simultaneously measure the dissolved oxygen and color. Secondly, automatic monitoring is performed to ensure that measurements are always taken at the same cuvette position. The fine-tuning of the device with the study of white and red wines makes it possible, on the one hand, to establish the appropriate measurement conditions and, on the other hand, to determine the amount of oxygen required to cause specific changes in the wine spectrum, information that could not be obtained until now. The preliminary results are very interesting, presenting precise data on the amount of oxygen consumed by the wine and the variations in its visible spectrum, thus reflecting the modification of the responsible phenolic compounds. This information is of great interest, since it helps to optimize the handling of the wine and, if necessary, to moderate the uptake of oxygen in each type of wine to ensure the maintenance of the color during the winemaking and conservation processes of each type of wine. The results of the experiments indicate that this new instrument is feasible and accurate for detecting oxygen changes during wine production.

Development of a New Strategy for Studying the Oxygen Consumption Potential of Wine through the Grape Extract Evaluation.

The development of a method to determine the aging potential of wine at the time of harvest, through the evaluation of its oxygen avidity, is a potential tool for the winemaking sector. To this end, it is necessary to formulate a potential wine with this grape prior to alcoholic fermentation. The main objective of this method was to optimize a formulation of the potential wine, based on the grape extracts (GEs), to subsequently evaluate its oxygen consumption kinetics, guaranteeing maximum differentiation between the different GEs. The optimization was carried out with a Taguchi orthogonal matrix design, which optimized the variables to be used in the GE reconstitution. The variables studied were pH, Fe2+, Cu2+, Mn2+, alcohol content and acetaldehyde. The evaluation of the characteristic parameters of the consumption kinetics of each of the GEs allowed us to know the different reconstitution conditions that most influence the differentiation of the oxygen consumption kinetics of very similar GEs. The reconstitution conditions chosen were pH 3.3; 1 mg/L Fe2+; 0.1 mg/L Cu2+; 1 mg/L Mn2+; 12% (v/v) alcoholic strength and 10 mg/L acetaldehyde, with pH, Fe2+ and Mn2+ being the significant conditions. The kinetics of reconstituted GE could be a tool for the classification and evaluation of grapes according to their aging potential or shelf life of the wine made.

Cranial aseptic osteomyelitis associated with pyoderma gangrenosum.

Neutrophilic dermatoses include a heterogeneous group of entities. Uncommonly, they can accumulate aseptic neutrophilic abscesses in other tissues in addition to the skin. A 34-year-old female complained of a headache which was unresponsive to usual drugs. A TAC revealed an osteolytic lesion in the right parietal bone. The biopsy showed osteomyelitis. One year later, pyoderma gangrenosum appeared in the anterior aspect of both legs. The headache and the cutaneous lesions disappeared after treatment with oral prednisone. The bone involvement in the background of neutrophilic dermatoses is exceptional. Usually, it involves children in the context of chronic recurrent multiple osteomyelitis (CRMO). Only two cases have been described in adults. One of them was a 26-year-old woman who had had CRMO since childhood, and the other one in contiguity with the cutaneous lesions of pyoderma gangrenosum.

Effect of rootstocks on volatile composition of Merlot wines.

BACKGROUND: Scion physiology and grape quality are impacted by rootstock choice. There is little available information about the effects of rootstock on wine volatile composition, particularly when comparing grafted with own-rooted grapevines. This field trial was aimed at studying the influence of rootstock choice on volatile composition of Merlot wines. RESULTS: Wines made from grapes harvested from own-rooted grapevines had the lowest content of (E)-3-hexenol, diethyl succinate and total ethyl esters and the highest content of 1-pentanol, 1-hexanol, (Z)-3-hexenol, diethyl malate and acetovanillone. Rootstocks such as 99R and 140Ru led to a higher content of total ethyl esters in wines followed by 110R, 1103P and Gravesac. According to odor activity values, Merlot wines were characterized by roses, sweat, cheese and banana aromas. CONCLUSIONS: This work provides valuable information about the potential impact of rootstocks on wine volatile composition for Merlot wines. © 2020 Society of Chemical Industry.

Experiencias sociocomunicativas en adultos mayores usuarios de audifonos / Socio-Communicative Experiences in Olders Adults Hearing-aid Headphones users

El presente artículo presenta un acercamiento real a las experiencias socio-comunicativas en los adultos mayores usuarios de audífonos, de la ciudad de Yopal. Gran parte del estudio se basa en la descripción de cuáles son las experiencias socio-comunicativas del adulto mayor que usa audífonos, incluyendo revisión teórica de varios autores que sustentan el beneficio de la ayuda auditiva en esta etapa de la vida. Teniendo en cuenta que la gran mayoría de los estudios relacionados con el uso de audífonos y su beneficio en el mejoramiento de la calidad de vida de los usuarios, no incluyen las experiencias socio-comunicativas de las personas adultas mayores, luego del proceso de adaptación, se pretendió indagar más profundamente sobre estas. Se aplicaron encuestas a un grupo de 20 adultos mayores entre 60 y 93 años, tanto hombres y mujeres, de la ciudad de Yopal ( Casanare- Colombia), quienes utilizan audífonos hace más de un año. Con los resultados obtenidos, se logró recolectar información, mediante un estudio cuantitativo, que permitió identificar, categorizar y analizar cada una de las experiencias de los adultos mayores, bajo los parámetros de actividades y participación, utilización de dispositivos y técnicas de comunicación, actividades recreativas y de ocio, actividades culturales (iglesia, grupos de apoyo), según lo planteado en la Clasificación Internacional del funcionamiento, la discapacidad y la salud (CIF).

This article presents a real approach to socio- communicative experiences in elderly hearing-aid users in the city of Yopal. Much of the study was based in the description of these experiences in the elderly that use hearing aids, including a theoretical review of several authors who support the benefits of these aids in this stage of life. Considering that, most research about hearing aids and their benefits in improving the users' quality of life does not include real socio-communicative experiences of the elderly after the adaptation process, this study pretended to investigate further into them. To achieve this, surveys were conducted to a group of 20 participants, both men and women, between 60 and 93 years old from Yopal ( Casanare- Colombia), who had been using hearing aid for a year. With the obtained results, this paper achieved to collect data through a quantitative study that allowed to identify, categorize, and analyze the experiences of the elderly, based on the activities' benchmarks and participation; devices' uses, communication techniques, leisure and cultural activities (churches and support groups), under the guidelines of ICF (International Classification of Functioning, Disability and Health).

CONCLUSION: In the 2010-2015 period, a sustained but insufficient trend of better control of HbA1c, BP and LDL was observed in patients with diabetes. The frequency of the measurements of these parameters improved more than the control of them. It seems that efforts to improve care for the patient with diabetes pay off, but they still have to be maintained

Volatile composition of Carignan noir wines from ungrafted and grafted onto País (Vitis vinifera L.) grapevines from ten wine-growing sites in Maule Valley, Chile.

BACKGROUND: Carignan noir is one of the minor and ancient varieties from the Chilean wine scenario that has had a resurgence as a result of to its rediscovered oenological potential when cultivated under the conditions of the interior dryland area. Under these growing conditions Carignan noir wines stand out as fruit driven and fresh compared to those originating from other growing areas. On the other hand, it is well known that wine aroma composition depends mainly on variety, viticultural management and winemaking. Thus, the present study aimed to investigate the volatile composition of wines from Carignan noir grapes originating from ungrafted and grafted onto País grapevines, in ten sites of the Maule Valley (Chile) during two consecutive vintages. RESULTS: Higher alcohols were the most abundant volatile compounds, whereas ethyl esters and ß-damascenone were the most odoriferous compounds according to their odorant activity value. The dominant factor in Carignan noir wine volatile composition was season, whereas rootstock did not have a significant effect in differentiating the wines. In terms of climate, cold nights during the month prior to harvest correlated with higher linalool, α-terpineol and trans-3-hexen-1-ol content. The biologically effective degree-days index was inversely correlated with isoamyl acetate and 2-phenylethyl acetate content. Huglin's heliothermal and the average mean temperature of the warmest month indices were inversely correlated with ethyl vanillate, ethyl hexanoate and ethyl octanoate content. CONCLUSION: Site climate conditions were related to the accumulation of certain wine volatile compounds. This information may be useful for devising new Carignan noir vineyard management strategies when aiming to improve wine quality or adjust site selection approaches to maximize grape/wine volatile composition according to wine style. © 2018 Society of Chemical Industry.

An Approach to the Study of the Interactions between Ellagitannins and Oxygen during Oak Wood Aging.

During the aging of red wine in oak wood barrels, or in alternative aging systems, interactions between the compounds released from wood, the compounds of the wine, and oxygen can take place. The main objective of the present work was to study oxygen-ellagitannin interactions by monitoring their levels in three model systems, all containing the same amounts of French oak chips and differing only in the oxygen content: total absence, only the oxygen released from the chips, and air-saturated (model systems F, OW, and OS, respectively). This study has highlighted the influence of oxygen in the ellagitannins' evolution and the relevance of the oxygen trapped into the oak chips, reporting for the first time the kinetics of oxygen release to the model wine. Furthermore, the indirect contribution of oxygen to the ellagitannins' disappearance by boosting autoxidative reactions has also been pointed out. Vescalagin seems to be the ellagitannin most affected by the initial oxygen levels.

Impact of fetal chromosomal disorders on maternal blood metabolome: toward new biomarkers?

OBJECTIVE: This study aimed at determining the relationship between fetal chromosomal disorders (CDs), including trisomy 21 (T21), and on first- and second-trimester maternal blood plasma, to identify the time-course metabolic adaptations to the conditions and the possible new plasma biomarkers. Furthermore, a definition of a joint circulatory (plasma) and excretory (urine) metabolic description of second-trimester CDs was sought. STUDY DESIGN: Plasma was obtained for 119 pregnant women: 74 controls and 45 CD cases, including 22 T21 cases. Plasma and lipid extracts (for T21 only) were analyzed by nuclear magnetic resonance spectroscopy, and data were handled by variable selection and multivariate analysis. Correlation analysis was used on a concatenated plasma/urine matrix descriptive of second-trimester CD, based on previously obtained urine data. RESULTS: CD cases were accompanied by enhanced lipid ß-oxidation (increased ketone bodies) and underutilization of glucose, pyruvate, and citrate. Lower circulating high-density lipoprotein levels were noted, along with changes in the proline and methanol in the first trimester, and also the urea, creatinine, acetate, and low-density lipoprotein plus very low-density lipoprotein in the second trimester and the different urea and creatinine levels, suggesting fetal renal dysfunction. In terms of plasma composition, T21 cases were indistinguishable from other CDs in the first trimester, whereas in the second trimester, increased methanol and albumin may be T21 specific. Furthermore, first-trimester lipid extracts of T21 showed decreased levels of 18:2 fatty acids, whereas in the second trimester, lower levels of 20:4 and 22:6 fatty acids were noted, possibly indicative of inflammation mechanisms. In both trimesters, high classification rates for CDs (88-89%) and T21 (85-92%) generally relied on variable selection of nuclear magnetic resonance data. Plasma/urine correlations confirmed most metabolic deviations and unveiled possible new ones regarding low-density lipoprotein plus very low-density lipoprotein, sugar, and gut-microflora metabolisms. CONCLUSION: This work partially confirmed previously reported data on first-trimester T21 and provided additional information on time-course metabolic changes accompanying CD and T21, in particular regarding plasma lipid composition. These results demonstrate the potential of plasma metabolomics in monitoring and characterizing CD cases; however, validation in larger cohorts is desirable.

Primary leptomeningeal histiocytic sarcoma in a patient with a good outcome: a case report and review of the literature.

INTRODUCTION: Histiocytic sarcoma is a rare neoplasm with few cases reported in the literature of which some were diagnosed in animals. This neoplasm arises from abnormal reticuloendothelial system cell proliferation of histiocytes and has an aggressive behavior especially if located in the central nervous system. We present the first case of a patient with histiocytic sarcoma that involved the meninges and had a good course after multidisciplinary treatment. CASE PRESENTATION: Our patient was a 41-year-old Caucasian woman with no previous history of disease who started with systemic symptoms such as headache and chills. Magnetic resonance imaging with gadolinium contrast of the brain suggested a mass 1.5×2cm in diameter in the temporal lobe with a non-uniform vasogenic edema. This lesion was implanted in the meninges and surgery was the first treatment. The histological findings revealed a histiocytic sarcoma. The patient received concomitant chemoradiotherapy after surgery with good tolerance and currently lives without disease. CONCLUSION: Although histiocytic sarcomas in the brain present an unusual location and have a poorer prognosis, we have identified the first primary leptomeningeal histiocytic sarcoma with a disease-free survival greater than 3 years following multidisciplinary treatment with surgery and chemotherapy and radiotherapy.

Predictores de fragilidad en el anciano / No disponible

Objetivo: Identificar predictores de fragilidad en el anciano. Material y métodos: Se realizó una revisión sistemática para obtener posibles predictores de fragilidad en el anciano que, posteriormente, fueron evaluados por un panel multidisciplinar de expertos mediante metodología Delphi en tres rondas. De la revisión sistemática de la literatura se obtuvieron 16 predictores de fragilidad en el anciano, cada uno de ellos se concretó en un capítulo, en total se elaboraron 271 preguntas respecto a los predictores repartidas en estos 16 capítulos. Cada experto calificó los predictores de fragilidad mediante una escala tipo Likert del 1 al 9 (1 = predecía MUY MAL la fragilidad y 9 = predecía MUY BIEN la fragilidad). Los predictores de fragilidad que obtuvieron una puntuación con una mediana mayor de 7 fueron considerados como buenos predictores. Resultados: Los expertos coincidieron que algunas variables eran, por sí mismas y de forma independiente, predictoras de fragilidad: trastorno de la movilidad, caídas y alteración de las actividades básicas de la vida diaria, deterioro cognitivo, riesgo de sufrir úlceras por presión, pluripatología, aspectos sociodemográficos y ambientales (sólo existió consenso en la infraestructura del lugar de residencia), trastorno del ánimo (depresión, ansiedad y trastornos del sueño), deterioro visual y/o auditivo. Conclusión: No se ha encontrado una herramienta validada para identificar fragilidad, aunque se pueden agrupar en 16 categorías los posibles predictores y ello podría proporcionarnos una herramienta de detección de fragilidad en el anciano(AU)

Objectives: To define predictors of frailty in the elderly. Methods: A systematic review had been conducted in order to obtain possible predictors of frailty in the elderly. The predictors were evaluated by an expert in older adult’s care panel by three rounds of Delphi methodology. As a result of the systematic review of literature, 16 frailty predictors were obtained, and each predictor was included in a chapter. We have elaborated 271 questions about the frailty predictors. Every expert in the panel used a Likert scale from 1 to 9 (1 = predicted VERY BAD frailty, while 9 = predicted VERY GOOD frailty). Frailty predictors that obtained a median score higher than 7, were considered as good predictors. Results: Experts agreed that some variables were frailty predictors, by themselves and independently: mobility disorder, falls and limitation to basic activities of daily living, cognitive impairment, risk of pressure ulcers, multiple pathologies, socio-demographic features and environmental factors (there was consensus only regarding residence infrastructure), mood disorder (depression, anxiety and sleep disorders), and visual/hearing impairment. Conclusions: There is no single validated tool to identify frailty, though we found the possibility to group into 16 categories the possible predictors, and it would be helpful for the detection of frailty in the elderly(AU)
