It is a well-known fact that consumers may gain significant benefits from the effective use of IoT in pandemic and post-pandemic settings. Security vulnerabilities can be seen in the ever-increasing Internet of Things (IoT) ecosystem from cloud to edge, which is crucial to note in this particular circumstance. Most merchants, even luxury stores, have failed to implement robust IoT cyber security procedures. Therefore, the researchers sought to put forth secondary research methodologies to bring forward efficient scrutiny regarding this particular issue to properly comprehend the influence of IoT in various devices, including a smartwatch, power displaying metre, brilliant weight showing gadgets and many more. The secondary research approach allowed the researchers to collect a large quantity of data quickly, acquiring a wide range of possible solutions for security and privacy issues in Consumer IoT (CIoT) devices. Secondary research also will enable scholars to compare and contrast several papers' philosophies and research findings to get a quick conclusion. To gather information, the researchers used publications and the internet efficiently. In this situation, it helped to save a significant amount of time. Findings suggested that vulnerabilities occur in smart IoT gadgets, including the intelligent power consumption metre and brilliant weight displaying widget, due to their low-standard and conventional security system. Thus, this paper has suggested possible solutions to protect IoT devices against phishing and theft attacks.

Published: July 2022

Matroids are the combinatorial structure and Greedy algorithmic methods always produces optimal solutions for these mathematical models. A greedy method always selects the option that looks best at each step of process of finding optimal solution. In other words, it selects a choice which is optimal choice locally in such a strategy that this locally chosen option may direct to a solution that will be globally optimal. It is true that while selecting locally optimal solution at each stage, Greedy algorithms may not always yield optimal solutions [1-2], but if we can transform an unknown problem into matroid structure, then there must be a greedy algorithm that will always lead optimal solution for that unknown problem. The range of solutions provided by Greedy is large as compared to the applicability of the Matroid structure. In other words the problems that can be translated into Matroid structure is proper subset of set of all problems whether Greedy algorithm produces optimal solution. Matroid structure thus ensures the global optimal solution one can obtain with help of Greedy approach. We study various logarithmic and linear hierarchical based mathematical models from divergence sources to maximize our information for research purposes. We analyze the time complexity and provide constrains over the upper/lower bounds in correspondence with the optimal (maximum/minimum) solution. We try to establish the relationship between the maximization of information divergences, the optimal-likelihood theory, and classified sharing is instituted. We propose integration of unknown rough sets to matroids in this paper. Particularly, we devise methodically the upper and lower tightening bounds on rough matroids which may expand up to the generic combinatorial matroid structure. The relationships are established by the upper and lower tightening bounds approximations of generalized combinatorial rough sets based on different interdependent relation sets, respectively [4]. As we define the generalized lower/upper bounds for rough matroid, we define a new structure for lower/upper greedoid leading to generalization of the greedoid [5]. Additionally, based on the new established relation, the generalized rough set also provides a theory of poset matroid.

Published: July 2022

During the signal identification process, massive multiple-input multiple-output (MIMO) systems must manage a high quantity of matrix inversion operations. To prevent exact matrix inversion in huge MIMO systems, several strategies have been presented, which can be loosely classified into similarity measures and evolutionary computation. In the existing Neumann series expansion and Newton methods, the initial value will be taken as zero as a result wherein the closure speed will be slowed and the prediction of the channel state information is not done properly. In this paper, fish swarm optimization algorithm is proposed in which initial values are chosen optimally for ensuring the faster and accurate signal detection with reduced complexity. The optimal values are chosen between 0 to 1 value and the initial arbitrary values are chosen based on number of input signals. In the proposed work, Realistic condition based channel state information prediction is done by using machine learning algorithm. Simulation results demonstrate that the suggested receiver's bit error rate performance characteristics employing the Quadrature Amplitude Modulation (QAM) methodology outperform the existing Neumann series expansion and Newton methods.

Authors: T R Yashavanth , M Suresh
Published: July 2022

Biometric systems have gained acceptance in a variety of industries in recent years, and they continue to improve security features for access control systems. Numerous types of monotonic biometric systems have been developed. On the other hand, these systems can only provide low- to mid-level security features. As a result, combining two or more collinear biometrics are necessitated for significantly greater functionality. In this paper, a multimodal biometric technology for iris, face, and fingerprint assimilation has offered. Here, an effective matching approach based on Principal Component Analysis that employs three biometric modes to solve this challenge: iris, face, and fingerprint. The three modalities are integrated at the score level fusion, and fusion is conducted. Here, authors have proposed a combination of Iris-Fingerprint, Iris-Face, and Face-Fingerprint to develop the model. Statistical parameters like True positive (TP), True Negative, False positive, False Negative, F1 score, Accuracy are tested for different threshold values. For Iris-Fingerprint, Iris-Face, and Face-Fingerprint, our suggested technique yields accuracy of 79 percent, 85 percent, and 82 percent, respectively. Finally, a ROC curve was created using a Linear Support Vector Machine for all of the combinations, with an Area under Curve of 0.83 for the fusion of Iris and Face.

Cascaded H-bridge multilevel inverters are becoming increasingly used in applications such as distribution systems, electrical traction systems, high voltage direct conversion systems, and many others. Despite the fact that multilevel inverters contain a large number of control switches, detecting a malfunction takes a significant amount of time. In the fault switch configurations diode included for freewheeling operation during open-fault condition. During short circuit fault conditions are carried out by the fuse, which can reveal the freewheeling current direction. The fault category can be identified independently and also failure of power switches harmed by the functioning and reliability of cascaded H-bridge multilevel inverters. This paper investigates the effects and performance of open and short switching faults of multilevel inverters. Output voltage characteristics of five level MLI are frequently determined from distinctive switch faults with modulation index value of 0.85 is used during simulation analysis. In the simulation study, with the modulation index value of 0.85, one second open and short circuit faults are generated for the location of the defective switch. Fault is identified automatically by means of artificial neural network technique using sinusoidal pulse width modulation based on distorted total harmonic distortion and managed by its own. The proposed topology is to be design and evaluate using MATLAB/Simulink platform.

Published: July 2022

The modern scientific growths in optical networks based on wavelength division multiplexing (WDM) are more attractive to satisfy the high bandwidth requirements of the modern internet infrastructure. Moreover, they potential to satisfy the future bandwidth requirements.WDM optical networks act as the backbone for telecommunication and high-performance communication networks. Multicast communication is the simultaneous transmission of data from one source node to many destination nodes available in the network over wavelength division multiplexing. It is extensively deployed in high performance computing and communication networks. In this article, a linear array and ring networks are extended by directly linking all nodes which are separated by two intermediate nodes with additional fibers which is referred as linear array and ring network with 3-length extension. The wavelength allotment methods are proposed to realize one-to-many communication over wavelength division multiplexing optical linear array and ring with 2-length extension under longest link first routing and the minimum wavelength number needed is determined. The minimum wavelength number needed to support for the extended linear array is reduced approximately by 20% when compared with that of a linear array network and for the extended unidirectional ring is reduced approximately by 25% when compared with that of a unidirectional ring network. And also, for the extended bidirectional ring the minimum wavelength number is reduced approximately by 33% when compared with that of bidirectional ring network.

Seismic analyses for power transformers
Authors: Platek Robert , Juszkiewicz Grzegorz
Published: July 2022

Reliability and security of power systems, especially in areas prone to earthquakes, depends on the seismic withstand of its components and interaction of these components with other elements. All relevant power products and components should be designed and tested to guarantee high seismic performance. Option which is strongly recommended for seismic qualification is shake table test. This way is very expensive and in some cases like power transformers impossible due to its weight and size. Because of this the numerical analyses can be very helpful to determine the dynamic characteristic of the system. This way is more and more used during evaluation of seismic performance of power products, especially in the design phase. In the paper a different numerical approaches for seismic analyses of the power transformers have been presented. In the first part of the article focus was put on typical simulation methods defined by IEEE and IEC standards. This approach is dedicated only for transformer’s components. Due to fact that standards do not provide clear information about fluid influence on power equipment during seismic events, some investigations related with oil filled transformers were done and summarized. Three different numerical methods were investigated. First one is built based on the Fluid-Structure Interaction (FSI) methodology. In this approach combination of different software (CFD, structural, and coupling code) is used to cover phonemes related with fluid dynamics and structural analyses. FSI methodology gives a wide possibility but, it’s very complex however, is very complex which can be a disadvantage for very complex objects. Next one uses acoustic elements, where the fluid is modeled as acoustic medium. This is method which allows to take into account fluid during seismic simulations in simplified way. The last one uses Lagrange and Euler element formulations (CEL) in which sloshing effect of the oil in power products can be considered. All this approaches can be very helpful to determine the dynamic characteristic of the transformers and its equipment including fluid.
Influence of winding capacitances to ground modelling on the calculation of transferred voltages in power transformer
Authors: Capuder Kosjenka , Plišić Goran
Published: July 2022

During voltage transients, the windings of a transformer are coupled by electric and magnetic fields. To calculate the transients inside the transformer, a network model is typically used. The accuracy of obtained calculation results depends mainly on this model in which the windings are lumped into R, L and C circuit components. The windings are usually represented by discs, or groups of discs, with the corresponding resistances, inductances (self and mutual) and capacitances (series and to the ground) [1]. In case of impulse voltage, wave’s steep front and consequently high frequency oscillations are the main reason why capacitances modelling is of major importance for the calculation of voltage distribution in winding and between windings.

First data on DNA barcoding of representatives of the genus Cеntaurea s.l. (Asteraceae) from Bulgaria
Authors: Bancheva Svetlana , Vladimirov Vladimir , Boycheva Irina , Bonchev Georgi
Published: July 2022

The genus Centaurea s.l. is one of the richest and most taxonomically complex of the Asteraceae family. It includes between 400 and 700 species, of which more than 70 are found in Bulgaria – a territory considered as one of the secondary centers of speciation of the genus. There is a large number of endemics (Bulgarian and Balkan) with endemism reaching up to 50% in some groups, such as Cyanus gr. Due to the ongoing active speciation in the Balkans, the boundaries between closely related taxa cannot be easily established based entirely on morphological features. DNA barcoding is cost-efficient and reliable approach for identifying and retrieving previously known species with the potential to accelerate the discovery of new plant species. Despite the huge potential of the method, no any Bulgarian population from this genus has been barcoded so far. The present study presents the first DNA barcoding data of 11 species of the genus Centaurea s.l. from 12 populations based on four regions – ITS, matK, rbcL and trnH-psbA. The first three DNA barcodes are promising whereas the trnH-psbA has somewhat lower resolution. The preliminary results suggest that the ‘Cyanus’ group is well separated from the ‘Centaurea s.str.’ group which corresponds well to their treatment as different subgenera or genera. Within ‘Cyanus’, grouping of taxa corresponds well to the morphology of the species. Within ‘Centaurea s.str.’, although a relatively low number of species has been included, grouping of taxa in most cases is congruent with the morphological characters. However, there are some incongruent tree topologies which should be investigated further both by repeating the extraction and sequencing of the samples, and by addition of new, presumably closely related species in the study.
Phylogenetic identification of Balkan endemic Stachys species and genomic stability during ex vitro conservation
Authors: Mantovska Desislava , Bonchev Georgi , Zhiponova Miroslava , Yordanova Zhenya
Published: July 2022

The genus Stachys is one of the largest in the Lamiaceae family. Representatives of the genus are among the most ancient medicinal plants used in the ethnomedicine. The Balkan endemic species S. thracica, S. bulgarica and S. scardica are included in The Red Data Book of Bulgaria and due to their endangered status are scarcely studied. The aim of the present work was to examine the genetic status of these three endemic Stachys species during the process of their ex situ conservation. To gain information about their taxonomic position in the genus Stachys, we applied the DNA barcoding approach. Nuclear (ITS) and plastid (rbcL, matK and trnH‑psbA) DNA barcodes were generated and aligned with accessions available in the data base. In the constructed phylogenetic trees S. thracica was placed in a cluster together with S. alpina, S. germanica and S. cretica, while S. bulgarica and S. scardica were clustered with S. officinalis. The ex situ conservation was achieved by the initiation of in vitro shoot cultures and their subsequent adaptation in ex vitro conditions. To check the genomic stability of the plants during the acclimatisation from in vitro conditions to ex vitro, analysis by sequence-related amplified polymorphism (SRAP) markers was performed. No difference was detected between the SRAP profiles of in vitro cultivated and ex vitro adapted S. thracica and S. scardica plants. In S. bulgarica, only 0.4% fragment difference was detected. The obtained results indicated that the three Stachys species preserved their genetic stability during the process of in vitro multiplication, which is a prerequisite for conserved bioactive capacity.

Analysis of Tafel polarization scans of Magnesium-Steel galvanic couple under different corrosive environments at various temperatures
Authors: Fahad Riaz Muhammad , Samiuddin Muhammad , Farooq Mudassir , Ali Shah Intizar
Published: July 2022

It is an attributed fact that magnesium, in normal conditions, behaves as active or anodic material and steel as a noble or cathodic material in a galvanic cell. In the current study, various experiments have been conducted to investigate the electrochemical behavior of magnesium and mild steel galvanic couples in tap water and 0.1M NaHCO3 corrosive environments at different temperatures (40 ℃ to 80 ℃). The potentiodynamic results have confirmed that in tap water, magnesium acts as an anode as it corrodes itself and protects steel surfaces under the influence of galvanic action at selected temperatures. However, magnesium became passive under 0.1M NaHCO3 making steel anodic, which deteriorates aggressively at higher temperatures in 0.1M NaHCO3. The polarity reversal phenomenon was also observed in the magnesium-steel couple when exposed to this environment. The microstructural examination has shown that passivation occurred due to the formation of an oxide layer that grew towards the steel side in the galvanic couple as the temperature increased. Thus, the study revealed that the magnesium would be more damaging to steel in a NaHCO3 environment if utilized in the temperature range of 60 ℃to 80 ℃.

Authors: Shigunov Neto Alexandre , Cunha Maria Isabel da , Silva André Coelho da
Published: July 2022

O objetivo deste texto é situar o surgimento, a normatização e a consolidação da pós-graduação no Brasil. Para isso, tomamos como base estudos sobre a história da educação brasileira e, especialmente, o parecer elaborado pelo professor Newton Sucupira, em 1965, à pedido do ministro da Educação. Destacamos que instituições de ensino superior e universidades foram criadas no Brasil apenas, respectivamente, a partir dos períodos imperial e republicano. Já o surgimento da pós-graduação se deu nos anos 1960, período pós 2ª Guerra marcado pela valorização do desenvolvimento e pelo entusiasmo com as ciências. Apontamos o fato de que o modelo brasileiro de pós-graduação, cunhado em plena ditadura militar, teve como inspiração o modelo estadunidense e visava formar docentes para o ensino superior, intelectuais que trabalhassem para o desenvolvimento do país e pesquisadores. Por fim, sinalizamos a vigência atual de ideais propostos por Sucupira em seu parecer e questionamos os rumos da pós-graduação brasileira diante dos cenários contemporâneos.

Leishmaniasis is a protozoan disease caused by species of genus Leishmania. Immunosuppression increases the risk of severe clinical forms and impairs response to treatment. The expansion of the use of immunomodulatory drugs for different conditions has raised the number of these cases. In this report, we present a case of visceral leishmaniasis in a patient with multiple sclerosis (MS) under fingolimod treatment. He presented with the triad of fever, visceromegaly, and pancytopenia and was diagnosed by the presence of amastigotes in a bone marrow sample. Furthermore, we discuss the previous published cases of MS patients under different immunosuppressant therapies to highlight its risk in endemic areas and suggest a therapeutic approach.

Published: July 2022

Prior to the COVID-19 pandemic, there was a rapid increase in international travel. Travel medicine is a branch of preventive medicine focusing on risk assessment pre-travel, during travel and post-travel with the aim of promoting health and preventing adverse health outcomes. Travel medicine specialists inform travelers about potential health risks and mitigate infectious disease risks such as travelers’ diarrhea, yellow fever, and malaria. Travel medicine topics were popular in the American Society of Tropical Medicine and Hygiene conferences between 2016 and 2020, and now comprise approximately 2% of all presentations. Most topics related to the post-travel assessment (50%), followed by diseases contracted during travel (26%), and pre-travel assessment and consultation (24%). Our analysis of the 10 sub-domains of travel medicine issues found that malaria (26%) and immunization (12%) were represented to the greatest extent. We anticipate that both travel and tropical medicine fields will regain their popularity after recovery from the pandemic.

Published: July 2022

Korea is one of the most advanced countries in kelp aquaculture. The brown algae, Undaria pinnatifida and Saccharina japonica are major aquaculture species and have been principally utilized for human food and abalone feed in Korea. This review discusses the diversity, population structure and genomics of kelps. In addition, we have introduced new cultivar development efforts considering climate change, and potential carbon sequestration of kelp aquaculture in Korea. U. pinnatifida showed high diversity within the natural populations but reduced genetic diversity in cultivars. However, very few studies of S. japonica have been conducted in terms of population structure. Since studies on cultivar development began in early 2000s, five U. pinnatifida and one S. japonica varieties have been registered to the International Union for the Protection of New Varieties of Plants (UPOV). To meet the demands for seaweed biomass in various industries, more cultivars should be developed with specific traits to meet application demands. Additionally, cultivation technologies should be diversified, such as integrated multi-trophic aquaculture (IMTA) and offshore aquaculture, to achieve environmental and economic sustainability. These kelps are anticipated to be important sources of blue carbon in Korea.

Published: July 2022

Kemoterapiyle ilişkili periferik nöropati, kanser tedavisinde kullanılan kemoterapik ajanların yol açtığı ciddi bir yan etkidir. Alınan kemoterapi kürleriyle giderek kötüleşen nöropati semptomları periferik sinir sisteminin duyu-motor-otonom bölgelerine hasar verebilmektedir. Bu derlemenin amacı kanser tedavisi alan çocuklara bakım veren hemşirelerin kemoterapiyle ilişkili periferik nöropati değerlendirmesindeki rolüne dikkat çekmektir. Kemoterapiyle ilişkili periferik nöropatinin ellerde-ayaklarda uyuşma, karıncalanma, kas/eklem ağrıları, yanma hissi, periferik reflekslerde azalma ve konstipasyon gibi belirtileri vardır. Bu belirtiler çocukların günlük yaşamını ve yaşam kalitelerini olumsuz yönde etkilemektedir. Kemoterapi ile ilişkili periferik nöropati görülme sıklığı kanserin tipine ve kullanılan kemoterapik ajana bağlı olarak değişmektedir. Vinkristin, sisplatin, taksan bazlı kemoterapik ajanların periferik nöropati geliştirdiği bilinmektedir. Kemoterapi tedavisi tamamlandıktan sonra bazı kemoterapik ajanların neden olduğu periferik nöropatiler azalsa da bazı ilaçların neden olduğu periferik nöropati bulguları uzun süre devam etmektedir. Hemşirelerin periferik nöropatiye yol açan kemoterapi ajanlarını bilmesi önemlidir. Hematoloji ve onkoloji servisinde çalışan pediatri hemşirelerinin, çocukların periferik nöropati semptomlarını nesnel olarak değerlendirebilecek ölçme araçlarından faydalanmaları gerekir. Nöropati değerlendirmesi hemşirelik bakımında bir rutin haline gelmelidir. Türkiye’de henüz kemoterapiyle ilişkili periferik nöropatiyi iyi bir şekilde değerlendiren bir ölçüm aracı bulunmamaktadır. Periferik nöropatiyi değerlendiren ölçüm araçlarının dilimize kazandırılması, hemşirelerin periferik nöropatinin semptomlarını (el ayaklarda karıncalanma, düğme ilikleme, merdiven inip çıkmada güçlük, yürürken sendeleme gibi duyusal, fonksiyonel ve otonom semptomlar, kas gücü ve derin tendon reflekslerinde azalmayı içeren fizik muayene bulguları) bilmesi ve nöropati değerlendirme araçlarıyla nöropatiyi değerlendirmesi önemlidir. Periferik nöropatinin yönetilmesinde farmakolojik yöntemlerin yanı sıra akupunktur, refleksoloji, masaj, ayak banyosu, kriyoterapi, scrambler terapi, progresif kas gevşeme egzersizleri, fiziksel aktivite gibi birçok farmakolojik olmayan yaklaşım bulunmaktadır ancak kanıtlar halen yetersizdir. Nöropatinin değerlendirilmesi ve yönetimi için klinik temelli çalışmalara ihtiyaç vardır.

Published: July 2022

Polyphenols constitute one of the most numerous and ubiquitous groups of fungal metabolites and are an integral part of the human diet. These molecules can be met as simple phenolic compounds or highly polymerized compounds. Recent interest in phenolic compounds has increased, owing to their antioxidant capacity. Besides, these compounds can have possible beneficial implications in human health, such as in the treatment and prevention of cancer, cardiovascular diseases, and other pathologies. Since there is little research done in Armenia, the data is scattered. This review aims to combine domestic and abroad papers on this matter.
The Uptake of Essential Mineral Elements by Endemic Salvia absconditiflora (Greuter & Burdet) Growing in Natural Habitats
Authors: ABACI-BAYAR Ahu Alev
Published: July 2022

This study was conducted to determine the uptake of essential mineral elements by endemic Salvia absconditiflora species growing in the natural habitats of Kırşehir province and its dependence on some physical and chemical properties of soil. The plant and soil samples were collected from 10 different locations. It was found that in the collected plants, K concentration was inadequate (0.344%), Fe had an excessive amount (541.853 mg kg-1), while Cu, Zn, Mn, Mg and Ca concentrations were adequate (6.154 mg kg-1, 32.610 mg kg-1, 43.395 mg kg-1, 0.507% and 3.650%). The soils had sandy clay loam texture, slight alkaline reaction (pH=7.92), an average amount of organic matter (3.06%), high amount of calcareous (35.61%) and low amount of soluble salts. It was also determined that soils had adequate K, Ca and Mg concentrations and 80% of the soil samples had inadequate level of P. Since Cu concentration was adequate in terms of microelement stock, concentrations of Zn were inadequate (0.292 mg kg-1). It was found that Salvia absconditiflora plant had the ability to grow in the soil with inadequate Zn and Mn.

Published: July 2022

The presented research aimed to statistically analyse the survival of 44,133 Polish Merino and Polish Merino in Old-Type lambs between birth and the 100th day of their life, using classification trees and logistic regression. The study included lambs born between 2008 and 2017 and used in 43 flocks in Pomerania and Kujawy region (Poland). The results showed that 9.27% of all controlled lambs did not survive till the 100th day of life. The statistical analysis of the case of lambs’ death during their first 100 days of life was carried out using multiple logistic regression as well as classification trees, using two algorithms CART and CHAID. The quality of multiple regression and decision tree models was compared considering the following criteria: percentage of misclassifications, average squared error and the area under the Receiver Operating Characteristic curve. The calculated quality criteria for tree models that were created during the research suggested that the classification trees formed based on CART algorithm were the most accurate in defining the variability of studied characteristics, i.e. survival of lambs up to the 100th day of age. For the best available classification model, the ranking of variable importance, developed based on the “Importance” measure, allowed to conclude that the type of lamb’s birth, season, following by the year of birth, subsequent lambing, lamb’s sex and its breed were the most significant differentiating factors. It was noted that the tree built with the use of CART algorithm was composed of 30 leaves. It was also shown that the highest frequency of lamb’s death during the rearing period was to be expected among triplets born in winter or summer (37.14% of all deaths), while the highest chance (98.42%) of surviving till the 100th day of life showed singletons, born from their mother’s 3rd to 6th litter, in the spring-winter season in the last year of the present research.

La endometriosis es una patología frecuente, crónica, estrógeno-dependiente, que se caracteriza por la proliferación de glándulas endometriales funcionales y estroma fuera de la cavidad uterina. Si bien la prevalencia varía según la población de estudio, aproximadamente el 10% de las mujeres en edad reproductiva en todo el mundo tienen endometriosis. Esta patología se produce cuando las células endometriales ectópicas se implantan, crecen y provocan una respuesta inflamatoria. La endometriosis, afecta con mayor a mujeres en edades reproductivas, sin embargo, hay registros en adolescentes y mujeres menopaúsicas; el tratamiento más aceptado incluye antiinflamatorios y anticonceptivos hormonales.

Published: July 2022

Introducción: El carcinoma de células de Merkel  constituye una variedad infrecuente de cáncer cutáneo (<1%), de origen neuroendocrino, de mal pronóstico por su patrón infiltrativo dermo-linfático. De su origen se vinculan dos posibilidades: la infección por poliomavirus y la radiación ultravioleta. Para su identificación se utilizan las características clínicas mediante el uso de la nomenclatura AEIOU, desglosada en el estudio. Caso clínico: Se reporta el caso de un paciente masculino de 86 años, con antecedente de neumonía por sars-cov2 (estado de inmunosupresión), masa tumoral en región malar izquierda, asintomática, de crecimiento rápido, en la cual se realiza biopsia, misma que reporta carcinoma neuroendócrino de células de Merkel con CK 20 positivo. Se decide manejo quirúrgico mediante resección amplia con estudio transoperatorio que confirma bordes libres de tumoración, parotidectomía superficial izquierda, vaciamiento radical izquierdo y posterior reconstrucción mediante colgajo fasciocutáneo semicircular de rotación tipo aleatorio y compensación en parte distal el cual permitió un buen resultado funcional y estético del paciente, precautelando el éxito del tratamiento oncológico. Conclusiones: los mejores resultados se obtienen cuando se combina un diagnóstico precoz y el tratamiento combinado con cirugía. En la escalera de reconstrucción tenemos varias opciones sin embargo por el amplio tamaño del área resecada y compromiso de la vascularidad se realizó la mejor opción con un colgajo fasciocutáneo aleatorio semicircular. Paciente con adecuada evolución, biopsia de ganglios negativos en espera para iniciar radioterapia.
