Optimal defect position in a DFB fiber laser
Authors: Nechepurenko Igor A. , Dorofeenko Alexander V. , Butov Oleg V.
Published: April 2021

Fiber lasers with compact cavity have numerous potential applications in sensing, communications, and medicine. Distributed feedback (DFB) rare-earth doped fiber lasers based on Bragg gratings with a phase shift are the most promising in this aspect. In this paper, we theoretically study such lasers and carry out a complex-frequency analysis of the DFB cavity modes. Our approach is based on the study of poles of open cavity response function and on the laser rate equations. An optimal defect position in the Bragg grating, which maximizes an output power towards one side, was found with this approach. We show that the optimal defect position depends on the pump power. At the pump level close to the lasing threshold, the defect should preferably appear in the middle of the grating to maximize the one-side output power. At higher pumping, the optimal position of the defect becomes asymmetric. We have found specific variables, which allow for determination of optimal defect position for a large variety of DFB laser configurations.
Terahertz generation from ZnTe optically pumped above and below the bandgap
Authors: Zhai Dongwei , Hérault Emilie , Garet Frédéric , Coutaz Jean-Louis
Published: April 2021

We report on the generation of THz waves through optical rectification in ZnTe of femtosecond laser pulses whose photon energy is tuned from below to above the ZnTe bandgap energy. The THz signal exhibits a pronounced peak at the bandgap energy, at THz frequencies for which losses in ZnTe remain small. This peak is likely due to the resonance of the ZnTe nonlinear susceptibility in the vicinity of the bandgap.

An extremely sensitive multi-order mode refractive index (RI) sensor was fabricated by coupling titanium dioxide nanograss film coated FTO conductive glass with Kretschmann prism. Both calculation and experimental studies were carried out. Theoretical analysis by employing resonant waveguide modes indicated that the maximum sensitivity could be achieved when the mode worked at the weakly-bounded condition. The experimental results showed that for p-polarized and s-polarized light, the sensor exhibited a maximum RI sensitivity of 2938.21 nm/RI unit (RIU) and 1484.39 nm/RIU in the 1st order mode, respectively. Its maximum figure of merit was as high as 77.77. The proposed sensor is promising to be applied in environmental monitoring, immune analysis, nucleic acid test, etc.
Plasmonic sensor based on metal-insulator-metal waveguide square ring cavity filled with functional material for the detection of CO2 gas

Published: April 2021

In this work, a straightforward and highly sensitive design of a CO2 gas sensor is numerically investigated using the finite element method. The sensor is based on a plasmonic metal-insulator-metal (MIM) waveguide side coupled to a square ring cavity filled with polyhexamethylene biguanide (PHMB) functional material. The refractive index of the functional material changes when exposed to the CO2 and that change is linearly proportional to the concentration of the gas. The sensors based on surface plasmon polariton (SPP) waves are highly sensitive due to the strong interaction of the electromagnetic wave with the matter. By utilizing PHMB polymer in the MIM waveguide plasmonic sensor provides a platform that offers the highest sensitivity of 135.95 pm/ppm which cannot be obtained via optical sensors based on silicon photonics. The sensitivity reported in this work is ∼7 times higher than reported in the previous works. Therefore, we believe that the results presented in this paper are exceedingly beneficial for the realization of the sensors for the detection of toxic gases by employing different functional materials.

Published: April 2021

Typical guided-mode resonance (GMR) transmission filter design, which is based on a single ridge per period, necessitates multiple etching/fabrication steps for implementing an array of filters (having different transmission bands) on the same substrate. To address this problem, we demonstrate dual-period narrow bandpass GMR filters that offer more degrees of freedom, two periods and two fill-factors, for tuning the filter characteristics and achieving wider stop bands without changing the grating height. A set of six transmission filters with well-separated passbands in the short-wave infrared region was designed using COMSOL Multiphysics simulations and produced on the same silicon-on-quartz wafer in a single fabrication run. The

Sarcomeres, the basic contractile units of striated muscle cells, contain arrays of thin (actin) and thick (myosin) filaments that slide past each other during contraction. The Ig-like domain-containing protein myotilin provides structural integrity to Z-discs—the boundaries between adjacent sarcomeres. Myotilin binds to Z-disc components, including F-actin and α-actinin-2, but the molecular mechanism of binding and implications of these interactions on Z-disc integrity are still elusive. To illuminate them, we used a combination of small-angle X-ray scattering, cross-linking mass spectrometry, and biochemical and molecular biophysics approaches. We discovered that myotilin displays conformational ensembles in solution. We generated a structural model of the F-actin:myotilin complex that revealed how myotilin interacts with and stabilizes F-actin via its Ig-like domains and flanking regions. Mutant myotilin designed with impaired F-actin binding showed increased dynamics in cells. Structural analyses and competition assays uncovered that myotilin displaces tropomyosin from F-actin. Our findings suggest a novel role of myotilin as a co-organizer of Z-disc assembly and advance our mechanistic understanding of myotilin’s structural role in Z-discs.
A direct comparison of theory-driven and machine learning prediction of suicide: A meta-analysis
Authors: Schafer Katherine M. , Kennedy Grace , Gallyer Austin , Resnik Philip
Published: April 2021

Theoretically-driven models of suicide have long guided suicidology; however, an approach employing machine learning models has recently emerged in the field. Some have suggested that machine learning models yield improved prediction as compared to theoretical approaches, but to date, this has not been investigated in a systematic manner. The present work directly compares widely researched theories of suicide (i.e., BioSocial, Biological, Ideation-to-Action, and Hopelessness Theories) to machine learning models, comparing the accuracy between the two differing approaches. We conducted literature searches using PubMed, PsycINFO, and Google Scholar, gathering effect sizes from theoretically-relevant constructs and machine learning models. Eligible studies were longitudinal research articles that predicted suicide ideation, attempts, or death published prior to May 1, 2020. 124 studies met inclusion criteria, corresponding to 330 effect sizes. Theoretically-driven models demonstrated suboptimal prediction of ideation (wOR = 2.87; 95% CI, 2.65–3.09; k = 87), attempts (wOR = 1.43; 95% CI, 1.34–1.51; k = 98), and death (wOR = 1.08; 95% CI, 1.01–1.15; k = 78). Generally, Ideation-to-Action (wOR = 2.41, 95% CI = 2.21–2.64, k = 60) outperformed Hopelessness (wOR = 1.83, 95% CI 1.71–1.96, k = 98), Biological (wOR = 1.04; 95% CI .97–1.11, k = 100), and BioSocial (wOR = 1.32, 95% CI 1.11–1.58, k = 6) theories. Machine learning provided superior prediction of ideation (wOR = 13.84; 95% CI, 11.95–16.03; k = 33), attempts (wOR = 99.01; 95% CI, 68.10–142.54; k = 27), and death (wOR = 17.29; 95% CI, 12.85–23.27; k = 7). Findings from our study indicated that across all theoretically-driven models, prediction of suicide-related outcomes was suboptimal. Notably, among theories of suicide, theories within the Ideation-to-Action framework provided the most accurate prediction of suicide-related outcomes. When compared to theoretically-driven models, machine learning models provided superior prediction of suicide ideation, attempts, and death.

Models for integrating and identifying the effect of senescence on individual tree survival probability for Norway spruce
Authors: Siipilehto Jouni , Mäkinen Harri , Andreassen Kjell , Peltoniemi Mikko
Published: April 2021

Ageing and competition reduce treesâ ability to capture resources, which predisposes them to death. In this study, the effect of senescence on the survival probability of Norway spruce ( (L.) Karst.) was analysed by fitting alternative survival probability models. Different model formulations were compared in the dataset, which comprised managed and unmanaged plots in long-term forest experiments in Finland and Norway, as well as old-growth stands in Finland. Stand total age ranged from 19 to 290 years. Two models were formulated without an age variable, such that the negative coefficient for the squared stem diameter described a decreasing survival probability for the largest trees. One of the models included stand age as a separate independent variable, and three models included an interaction term between stem diameter and stand age. According to the model including stand age and its interaction with stem diameter, the survival probability curves could intersect each other in stands with a similar structure but a different mean age. Models that did not include stand age underestimated the survival rate of the largest trees in the managed stands and overestimated their survival rate in the old-growth stands. Models that included stand age produced more plausible predictions, especially for the largest trees. The results supported the hypothesis that the stand age and senescence of trees decreases the survival probability of trees, and that the ageing effect improves survival probability models for Norway spruce.Picea abies

Published: April 2021

Egg and its product are easily perishable items because of their high moisture content, although they have a very high amount of nutrients, especially protein. Many efforts have been channelled to increase the shelf-life of these products but heat treatment according to literature is the most promising although egg and its products are heat-sensitive. Thus, a very low temperature is needed or a high temperature for a very short time. Ultra-Heat Treatment (UHT) is one of the known technologies that we used for heat-sensitive products.

The aim of the study was to investigate the effect of UHT treatment (approximately 67 °C for 190 seconds) on Liquid Egg Yolk (LEY) and Liquid Egg Yolk with additive (LEYA). During twenty-one days, the pH and colour were measured every seven days for all the samples. Emulsion stability was also studied by the methods of heat stability for mayonnaise. pH and colour measurements were used assess the quality of liquid egg yolks after 21 days of storage. From the results, raw LEY had the shortest shelf life and gave off a foul smell after 14 days of storage with significant colour changes. Addition of citric acid as an additive however improved the shelf life of the LEY with a relatively low pH. UHT treated LEY also showed improved shelf life of the LEY with a relatively constant pH from day 14 until the end of the experiment (day 21). UHT treatment of LEY with addition of addition of citric acid as an additive may help optimise the shelf life of the product.
Underlying causes of global food price changes
Authors: Gombkötő Nóra
Published: April 2021

There is a significant increase in food prices all over the world. Rate of annual increases in prices of all kinds of food is more than 100 percent. However, this can lead to long-term food crisis. The research aims to find out the factors that contribute to a large increase in food prices, as well as to predict the likely consequences of food price increases. Then potential solutions related to specific problems should be highlighted.  In this study several factors were determined, which were contributed to central (global food price increase) and general problems. These problems were separated by cause and consequences, they were structured and ordered hierarchically. Through outline the problems it can be improved that in global market of foods both demand and supply are influenced by many factors. The most important factors affected demand are: increase of population and urban population all over the world and increase of income level and internal migration in emerging countries. Supply is influenced by the following factors: a decrease in the yield of agricultural crops, low level of productivity in agricultural sector, as well as reduction in food crops production area because of unfavourable weather and increased production of biofuels. Most of general and specific factors, which affect food price increase, are related to each other causally but there are also separate factors. The most effective solution to the problem is increasing of agricultural productivity at the same time investments into agricultural researches and rural infrastructure.

The object of the trial was to study the effect of some lactic acid bacteria strains on the fermentation and aerobic stability of whole plant maize silages.The whole plant maize raw material was 32% DM, in soft cheddar stage of grain ripeness. It was ensiled in 4.2 litre capacity glass micro-size silos in 5 replicates /each treatment and stored on constant air conditioned room temperature (22 oC) during 95 days. The average packing density of raw material was 211 kg DM/m3.The applied treatments: 1. Untreated control maize, 2. Enterococcus faecium 100,000 CFU/g fresh maize (FM), 3. Lactobacillus plantarum 50,000 CFU/g FM + Enterococcus faecium 50,000 CFU/g FM, 4. Lactococcus lactis 100,000 CFU/g FM, 5. Lactobacillus plantarum 50,000 CFU/g FM + Lactococcus lactis 50,000 CFU/g FM, 6. Lactobacillus plantarum 100,000 CFU/g FM.Aerobic stability study:  Applied Honig (1990 system).The main experiences are the following: Applied lactic acid bacteria strains improved the quality of fermentation of maize in general compare to untreated control one.Lactic acid bacteria strains significantly stimulated lactic acid production and decreased propionic and butyric acid production. The origin of ammonia decreased also under influence of lactic acid bacteria strains in unaerobic conditions.Enterococcus faecium and.Lactococcus lactis are not able to protect the maize silages against the aerobic deterioration with the applied dosage.  Lactobacillus plantarum itself produced the most favourable fermentation characteristics and protected the aerobic stability of silage the most effectively (during 4 day) compare to all other treated maize silages.
Relation of wheat species and genomes in amino-acid composition
Authors: Pepo Pal
Published: April 2021

As regards wheat varieties constituting a natural ploid series the issue of analysing diploid, tetraploid and hexaploid species is topical since ancient varieties can play significant roles in contemporary agriculture as well. Seventeen winter wheat varieties, out of which 2 diploid varieties carried genome A, 9 diploidic types had genomes AB, two varieties had genomes AG and four varieties were hexaploid ones with genomes ABD, were analysed from the point of view of their amino acid compositions. The amino acid contents of Asp, Thr, Ser, Glu, Gly, Ala, Cys, Val, Met, Ile, Leu, Tyr, Phe, His, Lys, Arg, Pro (a total of 17) were determined in the varieties listed above.

It has been found that the amino acid contents of the grains genotype AA Triticum boeticum and T. monococcum exceeded the amino acid content of T. aestivum in respect of all the amino acids analysed in this experiment, with Glu being the only exception. In comparison with the aestivum wheat, essential amino acid contents showed a similarly favourable picture in the diploidic varieties mentioned. As regards type AB tetraploid varieties excesses of 13-16%, in comparison to the aestivum wheat, were found in essential amino acid contents. The amounts of non-essential amino acids in all the winter wheat varieties showed decreases irrespective of the ploid level.

What concerns the total amino acid content, all the winter wheat varieties with the exception of T. monococcum (A), T. dicoccoides (AB) and T. dicoccum (AB) contained less amino acid than the aestivum wheat. All the monocarbonic acid and aromatic as well as heterocyclic amino acid contents of the wildly growing Triticum boeticum (A) and the grown Triticum monococcum (A) (with polaric, apolaric R groups, diamino radicles) exceeded the same contents of T. aestivum. The value of the monoamino-dicarbonic acid, however, was lower in our experiment.

Published: April 2021

The watermelon (Citrullus lanatus, THUNB. Matsum & Nakai.) is an important and valuable vegetable crop that has the 3rd largest cultivated area in open field in Hungary. Our experiment was set up in the largest and most intensive melon growing area in Hungary, at Dombegyháza in Békés County. Our investigations were carried out with the Grizzly watermelon variety and during the experiment 5 different colors of plastic mulch (purple, transparent, green, black, and butter coloured) were used, the control was uncovered. In the field we measured the average weight of the fruits, and during our laboratory measurements we examined the following nutritional characteristics: invert and reducing sugar content, refraction and acidity. Based on the results of the two years of our study we can state that the different color of the plastic mulch did not show significant differences in the examined quantitative and qualitative parameters. Using plastic mulch soil covering between the rows in the watermelon production is likely to continue due to the fact that the fruits remain clean, between the rows the soil remains weed-free, and the problem of labor shortage can be solved with this technology.
Development of Lycoriella ingenua and Bradysia impatiens on different phases of agaricus composts
Authors: Kecskeméti Sándor , Fail József , Geösel András
Published: April 2021

Fungus gnats are small, dark colored, mosquito like fragile insects. They can be encountered all around the world, excluding places with extreme climate. Gnats prefer habitats that are damp with high relative humidity and rich in organic debris. Most of the species are not considered to be harmful in agriculture, but some may cause serious damage, especially in forcing of vegetable or ornamental plants. In mushroom production, however, they are considered as the most destructive pests; the damage caused by them alone can result in huge loss for mushroom farmers. In the Hungarian mushroom industry, fungus gnats damage mainly white-button mushroom, oyster mushroom and pioppino productions. Lycoriella ingenua (Dufour, 1839) and Bradysia impatiens (Johannsen, 1912) are the two most commonly found fungus gnat species from the family Sciaridae on Hungarian mushroom farms.

We have conducted an experiment with the two aforementioned species, to find out, whether they can fully develop into adults, feeding purely on Agaricus compost diet. We used unspawned white button mushroom compost (phase 2) and spawned compost which has been colonized by the mycelia of Agaricus bisporus (phase 3). We did not conduct any experiment with the first compost phase, as it undergoes pasteurization, which eliminates any pests in it. We recorded emerging gnats only from phase 2 compost. Neither L. ingenua, nor B. impatiens could complete its development on phase 3 compost diet, furthermore not even pupae were observed in these breeding pots. From pots containing phase 2 compost, a total of 1607 adults emerged. The number of B. impatiens adults was 653, and 954 for L. ingenua. Sex ratios for the two species were different. For B. impatiens, the number of females was 1.36 times greater than that of males, in L. ingenua there were 1.7 times more males than females in total. Swarming took approximately 6 days for B. impatiens and 10 days for L. ingenua. From the experiment we can conclude that phase 3 compost, which is well interwoven with Agaricus bisporus mycelia is not suitable for B. impatiens and L. ingenua to complete their whole life cycle.

A technológiai és társadalmi fejlődés hatására, a globalizálódó információs világnak köszönhetően környezetünk példátlan ütemben változik. Ennek hatásai természetesen a munka világában is tapasztalhatók. Új területek tűnnek fel szemünk előtt, miközben évtizedek óta űzött szakmák merülnek a feledés homályába. A szerzők tanulmányukban az Ipar 4.0, vagyis a vállalkozások digitális átállásával összefüggő humánerőforrás-kihívásokra helyezték a hangsúlyt, különös tekintettel arra, miként lehet felkészíteni a (leendő) munkavállalókat a digitális környezetben ellátandó feladatokra, s milyen kompetenciákat vár el a dolgozóitól egy, a digitalizációs folyamatban már lépéseket tett vállalkozás.

Published: April 2021

There are various measures currently in place to prevent the spread of COVID-19; however, in some cases, these can have an adverse effect on the acoustic environment in buildings. For example, transparent acrylic partitions are often used in eating establishments, meeting rooms, offices, etc., to prevent droplet infection. However, acrylic partitions are acoustically reflective; therefore, reflected sounds may cause acoustic problems such as difficulties in conversation or the leakage of conversation. In this study, we performed a prototyping of transparent acrylic partitions to which a microperforated panel (MPP) was applied for sound absorption while maintaining transparency. The proposed partition is a triple-leaf acrylic partition with a single acrylic sheet without holes between two MPP sheets. The sound absorption characteristics were investigated by measuring the sound absorption in a reverberation room. As the original prototype showed sound absorption characteristics with a gentle peak and low values due to the openings on the periphery, it was modified by closing the openings of the top and sides. The sound absorption performance was improved to some extent when the top and sides were closed, although there remains the possibility of further improvement. This time, only the sound absorption characteristics were examined in the prototype experiments. The effects during actual use will be the subject of future study.
A criação do Instituto Nacional de Cinema Educativo na Era Vargas: debates e circulação de ideias

O artigo que segue trata da criação do Instituto Nacional de Cinema Educativo (INCE), órgão gestado durante o primeiro governo Vargas e que foi inaugurado em 1936. A escolha do administrador do INCE, Roquette-Pinto, foi contextualizada durante o texto, algo que ajudou a explicar certos aspectos científicos alocados nos filmes do Instituto. Trago como fontes, trechos do Decreto-lei n. 21.240 de abril de 1932 que instituiu o órgão, artigos assinados pelo cineasta Humberto Mauro na revista A Cena Muda, recortes de discursos de autoridades políticas e pensadores da educação do período. Esses documentos apontaram para o alinhamento entre cinema educativo e propaganda política, além de trazerem à tona elementos vinculados a uma moral religiosa católica, cuja premissa foi moldar as narrativas cinematográficas produzidas por todo o cinema brasileiro do período, sobretudo o educativo.

Esta formação no Paraná adequou-se à Lei Orgânica do Ensino Normal de 02/01/1946, que se orientava pelas recomendações do BIE, ratificadas pela UNESCO a partir de sua constituição. Busca-se perceber como essas políticas para formação de professores (PR), articularam-se às políticas nacionais atendendo às recomendações do BIE. Os resultados apontam para as relações entre a Lei Orgânica do Ensino Normal (1946), as Recomendações do BIE e posteriores recomendações da UNESCO. O artigo mostra como as medidas tomadas pelo Secretário de Educação e Cultura do Paraná (1949-1951), procuraram atender às Leis Orgânicas, quanto à formação de professores para o ensino primário, nas zonas rurais e centros urbanos.
A trajetória das ideias políticas de Alceu Amoroso Lima: da contrarrevolução ao modernismo católico (1928-1938)
Authors: Souza Rodrigo Augusto de
Published: April 2021

Este artigo procura realizar uma análise da trajetória das ideias políticas de Alceu Amoroso Lima (1893-1983). O recorte temporal contempla o período de 1928 a 1938. Na investigação, parte-se do fenômeno de sua conversão ao catolicismo até o início do seu contato com as ideias de Jacques Maritain (1882-1973). Considera-se que nesse período Alceu Amoroso Lima começou uma mudança de posição política. Esse processo foi acompanhado de uma significativa transformação de suas ideias políticas. Assumindo a condição intelectual católico, Amoroso Lima engajou-se na militância contrarrevolucionária advinda da influência de Jackson de Figueiredo (1891-1928) sobre o seu pensamento. Mas, após o contato com as ideias de Maritain, mudou de posicionamento político, assumindo a democracia cristã como doutrina política para a sua militância no catolicismo.

El texto en comento es una obra que ha surgido por la unión de dos esfuerzos académicos: (i) La investigación sobre la vida y obra del sacerdote jesuita -Premio Nacional de Educación 1999-, iniciada hace algunos años por el Dr. Jaime Caiceo Escudero quien “ha escrito sobre todos los Premios Nacionales de Educación y recibió del propio padre Patricio, poco antes de su muerte, el encargo de escribir su biografía; ya en 2005 había plasmado una investigación científica sobre la vida y la obra del jesuita” (ROSSETTI ET AL., 2019, contratapa). (ii) Un grupo de académicos que trabajaron con el fundador del Centro de Investigación y Desarrollo de la Educación -CIDE- en la misma institución en diversas labores de investigación y publicación; ellos son Francisco Álvarez Martín, Cecilia Cardemil Oliva, Leonor Cariola Huerta, Josefina Rossetti Gallardo, Rosa Saavedra Díaz, quienes deseaban dejar por escrito el significado y la importancia en favor de la educación por el sacerdote de la Compañía de Jesús, “un innovador en la educación chilena” (IBIDEM). Ellos, a su vez, invitaron al académico de la Universidad Alberto Hurtado, Pablo Andrés Toro Blanco, a fin de que escribiera el “marco sociocultural y político de la época en que vivió el padre Patricio” (IBIDEM). Esta obra consta tres capítulos. El primero, denominado “El Chile que le tocó vivir”, escrito por el Dr. Toro, quien describe y analiza con bastante propiedad histórico-cultural-educacional el período que abarca 73 años del acontecer chileno (1928-2001) en 22 páginas; una síntesis de sus reflexiones apuntan a que “Cariola acompañó con su trayecto vital el tránsito desde un Estado que buscó garantizar la educación como un derecho y como un insumo central para la transformación de la sociedad, de acuerdo a proyectos colectivos de profundas raíces históricas y utópicos propósitos (el desarrollo, el socialismo), hacia una revolución capitalista que frustró esos proyectos para depositar la soberanía de las decisiones educacionales en el mercado” (IBID, pp. 33-34).

Nell'ultimo decennio il lembo antero-laterale di coscia (ALT) è diventato il lembo libero più utilizzato nella ricostruzione della lingua, dal momento che esso è caratterizzato da bassa morbidità a livello del sito donatore e da migliori risultati estetici. Tuttavia, l'ALT fascio-cutaneo può essere insufficiente nella ricostruzione nei difetti maggiori (es. glossectomia totale) mentre la sua variante muscolo-cutanea (che include il muscolo vasto laterale)' può essere troppo voluminosa. Scopo dello studio è quello di descrivere la nostra esperienza preliminare nella ricostruzione della lingua utilizzando il lembo libero mio-fasciale di vasto laterale che potrebbe a nostro parere offrire notevoli vantaggi nella ricostruzione testa-collo come: possibilità di confezionare un lembo voluminoso quando necessario, ottimi risultati funzionali, obliterazione di spazi morti con prevenzione dello sviluppo di fistola e infezione con minima morbidità a livello del sito donatore.

Lo scopo di questo studio è stato quello di dimostrare se pazienti affetti da disfonia organica presentino alterazioni posturali caratteristiche e se lintervento di fonomicrochirurgia delle corde vocali determini modificazioni dellassetto posturale. Sono stati esaminati 40 soggetti (22 maschi, 18 femmine; età media 32,6 ± 7,5 anni) affetti da disfonia organica (15 polipi cordali, 11 cisti da ritenzione sottomucosa, 10 noduli vocali fibrosi bilaterali e 4 edema di Reinke). Lassetto posturale è stato studiato mediante stabilometria statica in respirazione spontanea, ad occhi aperti e ad occhi chiusi, in tre diverse fasi: prima dellintervento chirurgico, 24 ore dopo la chirurgia e 6 mesi dopo lintervento. Le variabili prese in considerazione sono state: le coordinate del centro di pressione sul piano frontale e sagittale, la lunghezza e la superficie della traccia, la velocità media delle oscillazioni e le relative deviazioni standard, lanalisi spettrale della frequenza di oscillazione e i valori di statokinesigramma e stabilogramma. Nessun pattern patologico caratteristico veniva rilevato alla stabilometria in condizioni basali nei diversi sottogruppi di pazienti (polipi, cisti, edema di Reinke). Solo il sottogruppo di pazienti con noduli vocali bilaterali fibrosi (8/10; 80%) mostrava un lieve spostamento in avanti del centro di gravità sia ad occhi aperti che ad occhi chiusi. In tutti i sottogruppi non si verificavano modificazioni significative delle variabili stabilometriche ad occhi aperti e ad occhi chiusi, prima e dopo lintervento chirurgico. Luso della stabilometria statica, in questo studio, dimostra lassenza di alterazioni posturali caratteristiche nei casi di disfonia organica ed esclude che la semplice rimozione della lesione cordale, unilaterale o bilaterale, possa determinare variazioni posturali.

Le malformazioni linfatiche (LMS) sono masse cistiche benigne derivanti dallo sviluppo anormale dei canali linfatici. Le malformazioni linfatiche interessano principalmente il distretto testa-collo. L’asportazione chirurgica di malformazioni linfatiche è seguita da un alto tasso di recidiva e vi è un elevato rischio di complicanze. La bleomicina è un farmaco antineoplastico approvato. Tale farmaco può essere usato come agente sclerosante nelle anomalie vascolari. Presentiamo il caso di un bambino sottoposto a quattro interventi chirurgici senza successo, complicati da una paralisi periferica del nervo faciale. La malformazione linfatica è stata da noi trattata con successo con la somministrazione intralesionale di bleomicina.
