Authors: Gopurathingal Anto , Paul Nirvin , Kaganur Raghavendra , Jirel Abhishek , George Joseph
Published: February 2023

Introduction: Synovial hemangioma is a rare benign condition that is seen predominantly in the adolescent age group. Patients commonly present with pain and swelling of the involved joint. Here, we report a case of recurrent synovial hemangioma in a 10-year-old girl. Case Report: A 10-year old presented with complaints of recurrent swelling in her right knee of 3 years duration. She had complaints of pain, swelling, and deformity of her right knee. She had undergone a surgery to excise the swelling earlier for similar complaints elsewhere. She remained asymptomatic for a year, after which swelling reappeared. Conclusion: Synovial hemangioma is a rare benign condition that is often missed and needs to be promptly addressed to prevent damage to the articular cartilage. The chance of recurrence is high. Keywords: Synovial hemangioma, recurrence, sclerotherapy

Published: February 2023

Introduction: Plasma rich in protein derived from platelets also known as platelet-rich plasma (PRP) is a recent science being used in many fields of medicine including cosmetic and musculoskeletal treatment. It has a very good ability to promote healing and decrease pain when added to certain treatment protocols. Being a simple and minimally invasive method of treatment, it is over-looked as a treatment option for the early osteoarthritis (OA) of knee joint. Well-designed randomized controlled studies and research are needed to measure outcomes, durability of effect while being cost effective Aim of the Research Study: The aim of this study was to prove the use of PRP and its outcome in the clinical treatment of arthritic joint diseases of knee, progression of disease in people treated for early stage OA, and functional outcome of PRP injection in knee degenerative diseases. Materials and Methods: This study was study period-6 months, sample size-50, sample type-patient, and functional outcome assessed using knee osteoarthritis outcome score (KOOS). Methodology of Research Work: This study was aimed to prospectively quantify the effect of treatment with platelet-rich plasma (PRP) injection in patients with degenerative joint diseases. Degenerative joint disease treated using PRP injections with an average study period of 6 months was analyzed according to measure of pain at baseline and post-treatment using KOOS. Data Analysis: Collected data will be analyzed by SPSS Software Version 19. Primary Objective: PRP injections aim to relieve pain and to improve functional status of the patient. Results: PRP is effective with treatment for degenerative knee arthritis. The patients found excellent relief in pain and mobility. The range of movement and KOOS score was found to be improved with P < 0.001. Keywords: Platelet-rich plasma, cytokines, degenerative arthritis, knee osteoarthritis outcome scoring
Fast reconstruction of programmable integrated interferometers
Authors: Katamadze Konstantin , Bantysh Boris , Chernyavskiy Andrey , Bogdanov Yurii
Published: February 2023

Programmable linear optical interferometers are important for classical and quantum information technologies, as well as for building hardware-accelerated artificial neural networks. Recent results showed the possibility of constructing optical interferometers that could implement arbitrary transformations of input fields even in the case of high manufacturing errors. The building of detailed models of such devices drastically increases the efficiency of their practical use. The integral design of interferometers complicates its reconstruction since the internal elements are hard to address. This problem can be approached by using optimization algorithms [Opt. Express, 29, 38429 (2021)]. In this paper, we present a novel efficient algorithm based on linear algebra only, which does not use computationally expensive optimization procedures. We show that this approach makes it possible to perform fast and accurate characterization of high-dimensional programmable integrated interferometers. Moreover, the method provides access to the physical characteristics of individual interferometer layers

Published: February 2023

The planorbid gastropod genus Bulinus consists of 38 species that vary in their ability to vector Schistosoma haematobium (the causative agent of human urogenital schistosomiasis), other Schistosoma species, and non-schistosome trematodes. Relying on sequence-based identifications of bulinids (partial cox1 and 16S) and Schistosoma (cox1 and ITS), we examined Bulinus species in the Lake Victoria Basin in Kenya for naturally acquired infections with Schistosoma species. We collected 6,133 bulinids from 11 sites between 2014–2021, 226 (3.7%) of which harbored Schistosoma infections. We found 4 Bulinus taxa from Lake Victoria (B. truncatus, B. tropicus, B. ugandae, and B. cf. transversalis), and an additional 4 from other habitats (B. globosus, B. productus, B. forskalii, and B. scalaris). S. haematobium infections were found in B. globosus and B. productus (with infections in the former predominating) whereas S. bovis infections were identified in B. globosus, B. productus, B. forskalii, and B. ugandae. No nuclear/mitochondrial discordance potentially indicative of S. haematobium/S. bovis hybridization was detected. We highlight the presence of Bulinus ugandae as a distinct lake-dwelling taxon closely related to B. globosus yet, unlike all other members of the B. africanus species group, is likely not a vector for S. haematobium, though it does exhibit susceptibility to S. bovis. Other lake-dwelling bulinids also lacked S. haematobium infections, supporting the possibility that they all lack compatibility with local S. haematobium, thereby preventing widespread transmission of urogenital schistosomiasis in the lake’s waters. We support B. productus as a distinct species from B. nasutus, B. scalaris as distinct from B. forskalii, and add further evidence for a B. globosus species complex with three lineages represented in Kenya alone. This study serves as an essential prelude for investigating why these patterns in compatibility exist and whether the underlying biological mechanisms may be exploited for the purpose of limiting schistosome transmission.

Published: February 2023

Coronavirus disease (Covid-19) is a highly infectious disease caused by the SARS-CoV-2 virus and is associated with a decrease of respiratory, physical, and psychological function, subsequently affecting quality of life. The aim of the present pilot study was to use ultrasound imaging (USI) to evaluate and compare the thickness of the diaphragm and abdominal muscles between individuals recently diagnosed with moderate Covid-19 infection and healthy individuals. Methods: A cross-sectional observational pilot study was performed. A total sample of 24 participants were recruited from a private medical center (Madrid, Spain): Covid-19 (n = 12) and healthy controls (n = 12). The external oblique (EO), internal oblique (IO), transversus abdominis (TrA), rectus abdominis (RA), interrecti distance (IRD) and diaphragm thickness were assessed using USI during inspiration, expiration and during contraction. Results: USI measurements of the thickness of EO, IO, TrA, RA, IRD and the diaphragm did not differ significantly between groups during inspiration, expiration or during contraction (all P > 0.05). Conclusions: These preliminary results suggest that the morphology of the abdominal muscles and diaphragm is not altered in people with a recent history of moderate Covid-19 infection.

Authors: Dong Ying , Xiang Ziwei , Lu Huan , Zhang Lei , Zhao Zhiqi
Published: February 2023

Based on the perspective of ecology and innovation management, this paper selects seven elements from two aspects, innovation subject and innovation environment, to construct the evaluation index system for the health of pharmaceutical innovation ecological rainforest in Zhejiang from 2011 to 2019, together with the entropy weighted TOPSIS method and the obstacle factor diagnosis model. We find that the health of the pharmaceutical industry in Zhejiang can be measured as three stages: stagnation period, recovery period and development period. There is a relative balance between the development of innovation subject and innovation environment. The resilience of innovation subjects, followed by economic and cultural environment, is the key factor hindering the innovation of pharmaceutical industry in Zhejiang. Finally, we propose four countermeasures, including "deploying high-level service chains, broadening investment and financing channels for enterprises, building a reservoir of global talents, and creating an inclusive and open soft environment".

Introduction

The exact pathogenesis of fibromyalgia (FM) syndrome is unclear. However, various infectious have been implicated with the development of FM after their acute phase. We aimed to investigate the incidence of FM syndrome among convalesced individuals following hospitalization for Acute Coronavirus Disease-2019 (COVID-19).

Methods

We performed a cross-sectional study on patients who were discharged after COVID-19 hospitalization from the Sheba Medical Center, Israel, between July 2020 to November 2020. A phone interview was performed consisting of the following questionnaires: the Fibromyalgia Survey Diagnostic Criteria Questionnaire, Sense of Coherence Questionnaire to evaluate resilience, and the Subjective Traumatic Outlook Questionnaire to assess the associated psychological aspects of the trauma. The incidence of post-COVID FM was calculated and regression models were performed to identify predictors.

Results

The study population consisted of 198 eligible patients who completed the phone interview. The median age was 64 (52–72) and 37% were women. The median follow-up was 5.2 months (IQR 4.4–5.8). The incidence of FM was 15% (30 patients) and 87% (172 patients) had at least one FM-related symptom. Female gender was significantly associated with post-COVID FM (OR 3.65, p = 0.002). In addition, high median Subjective Traumatic Outlook scores and low median Sense of Coherence scores were both significantly associated with post-COVID FM (OR 1.19, p<0.001 and OR 0.92, p<0.001, respectively).

Conclusions

FM is highly prevalent among COVID-19 convalescent patients. Our finding suggests that a significant subjective traumatic experience and a low resilience are highly associated with post-COVID FM.
Can perceptuo-motor skills outcomes predict future competition participation/drop-out and competition performance in youth table tennis players? A 9-year follow-up study

Published: February 2023

Tools that provide a fair estimate of young table tennis players’ potential and their chances to succeed will support making decisions whether to commit to an extensive development program and the accompanying lifestyle. Consequently, this study included two research questions (RQ) to evaluate the capability of the Dutch perceptuo-motor skills assessment to predict competition participation/drop-out (RQ1) and competition performance (RQ2) in young table tennis players (n = 39; 7–11 years) using a tracking period of 9 years. The perceptuo-motor skills assessment consists of eight tests assessing gross motor function (i.e., sprint, agility, vertical jump) and ball control (i.e., speed while dribbling, aiming at target, ball skills, throwing a ball and eye-hand coordination). A Cox regression analysis demonstrated that a higher level of ball control was associated with a lower risk to drop-out from table tennis competition. The eye-hand coordination test appeared to be most suitable since it was the only test included in the multivariable Cox regression model (HR = .908; p = .001) (RQ1). Similarly, a multilevel regression analysis showed that a higher level of ball control was associated with a higher future competition performance. The eye-hand coordination and aiming at target tests were included in the multivariable multilevel model (p < 0.05; R2 = 36.4%) (RQ2). This evaluation demonstrates promising prospects for the perceptuo-motor skills assessment to be included in a talent development programme. Future studies are needed to obtain valid thresholds scores and clarify the predictive value in a larger sample of youth competition players.

Liposarcoma cervical
Authors: Losada-Campa Juan , Benito-Orejas José Ignacio , Bauer Michael , Torres-Morientes Luis Miguel , Álvarez-Quiñones-Sanz María , Santos-Pérez Jaime
Published: February 2023

Introducción: Menos del 1% de los tumores malignos son sarcomas, de ellos el 40% son liposarcomas, que se localizan en un 2% en cabeza y cuello. El subtipo “liposarcoma pleomórfico”, caracterizado por su alto grado de malignidad, capacidad de invasión, metástasis y recurrencia, es excepcional. Presentamos un caso clínico, destacando la importancia del tratamiento quirúrgico precoz.
Material y métodos: Varón de 70 años, que consulta por haberse notado un bulto en el cuello hace 3 días. La exploración física revela la presencia de una tumoración látero-cervical izquierda, localizada por debajo del esternocleidomastoideo (área III), móvil, elástica y no dolorosa. Resto de la exploración ORL normal.
Resultados: La ecografía cervical muestra una ecogenicidad heterogénea y la resonancia magnética evidencia una voluminosa masa cervical izquierda, única, de 8x4x4,5 cm, profunda al esternocleidomastoideo y superficial al eje vascular de composición mixta. El estudio citológico mediante punción con aguja (PAAF), objetiva la presencia de células tumorales malignas.
Tras la extirpación por cervicotomía, el diagnóstico anatomo-patológico concluye que se trata de un liposarcoma de tipo mixto.
Radioterapia posterior. 4 años libre de tumor.
Discusión: El liposarcoma de cuello predomina en adultos, con una edad media de 46 años y predilección por el sexo masculino. Se clasifica, desde el punto de vista histológico, en varios subtipos, basándose en la actividad mitótica y grado de necrosis y de diferenciación, siendo la mayoría de los liposarcomas de cabeza y cuello, bien diferenciados. El pleomórfico, uno de los más indiferenciados, es excepcional, con una supervivencia media del 50% a los 2 años.
Como en nuestro paciente, las técnicas de imagen no son concluyentes para el diagnóstico de malignidad y el aspecto encapsulado del liposarcoma, puede confundir.
En cuanto al pronóstico, se valora la histología, la localización, el tamaño y el tipo de tratamiento. Los mejores resultados terapéuticos se obtienen con la cirugía. La radioterapia estaría indicada en los tumores más indiferenciados, con márgenes afectados, de gran tamaño y de localización profunda, pero por su rareza, la literatura no estratifica qué tipo de pacientes se beneficiarían de un tratamiento multimodal.
Conclusión: El liposarcoma pleomorfo es una neoplasia excepcional, de difícil diagnóstico clínico y de mal pronóstico, por lo que, ante una masa cervical de consistencia firme y crecimiento progresivo, se debe indicar un tratamiento quirúrgico precoz, que puede marcar la diferencia en cuanto a los resultados y la esperanza de vida del paciente.
Pólipos nasales, cirugía de revisión e inflamación eosinofílica

Published: February 2023

Introducción y objetivo: El tratamiento de la poliposis nasal son los corticoides, y si fallan, la cirugía. Sin embargo, muchos pacientes necesitan cirugías sucesivas, por lo que necesitan mejores tratamientos La investigación básica sobre respuesta inmune inflamatoria tipo 2 en mucosa rinosinusal nos ofrece la posibilidad de bloquear la reacción inflamatoria inmunomediada en la mucosa de pacientes con poliposis nasal. Disponemos de anticuerpos monoclonales capaces de bloquear inmunoglobulinas Il-4 e Il-13, Il-5 y eosinófilos e IgE en la mucosa nasal. Dada la asociación entre pólipos nasales e inflamación tipo 2 en el 85% de los pacientes, el conocimiento sobre eosinófilos y terapias biológicas podría cambiar el manejo de las recurrencias de pólipos y podría evitar procedimientos sucesivos o cirugías radicales.Método: Revisamos una cohorte retrospectiva de pacientes sometidos a CENS en nuestro Departamento entre el 1 de enero de 2016 y el 30 de diciembre de 2020, con más de un año de seguimiento. Todos los procedimientos quirúrgicos se realizaron con la técnica descrita por Stammberger: se respetó la mucosa sana y se abrieron todas las cavidades sinusales patológicas. Las muestras de tejido quirúrgico se tiñeron con hematoxilina-eoxilina y se realizó la identificación de eosinófilos. Se investigó la tasa de cirugía de revisión quirúrgica. Finalmente, se comunica los datos de nuestra experiencia preliminar en productos biológicos para pacientes con pólipos nasales. Resultados: La tasa global de cirugía de revisión fue del 18%. Se realizó recuento de eosinófilos en 157 pacientes con pólipos nasales. De ellos, el 71% (n=111) presentó un recuento elevado de eosinófilos en las piezas quirúrgicas. Los pacientes con pólipos nasales y un recuento elevado de eosinófilos tuvieron una Tasa de Revisión Quirúrgica del 34,2% (38/111). Si los eosinófilos no estaban elevados en el tejido polipoideo, la Tasa de Revisión Quirúrgica fue del 16,6% (8/48), con diferencias significativas en la prueba de Chi-cuadrado (p=0,0125). La comparación de pacientes con alto recuento de eosinófilos en la mucosa reveló un OR de 3,2117 (IC95% 1,2440-8,2918). Se administra terapia biológica en 5 pacientes con asma grave mal controlada con corticoides y beta agonistas. A pesar del corto seguimiento, hasta la fecha no hemos reintervenido paciente tras biológicos.Discusión y Conclusiones: Muchos pacientes con pólipos nasales necesitan cirugías sucesivas, por lo que necesitan un mejor tratamiento. Es importante considerar los factores específicos del paciente que afectan las tasas de cirugía de revisión, como el recuento elevado de eosinófilos, para encontrar mejores tratamientos. Las terapias biológicas pueden cambiar el manejo de las recurrencias de pólipos y podrían evitar procedimientos sucesivos o cirugías radicales en estos pacientes de alto riesgo.

Authors: Álvarez-Álvarez Ignacio , Ballesteros-Pomar Marta , Martín-Villares Cristina , Fernández-Cascón Sara , Rodríguez-García Ana , Cid-Martínez Marina , Martín-Sigüenza Gerardo
Published: February 2023

Introducción y objetivo: Los abordajes transmandibulares forman parte del arsenal quirúrgico de nuestra Especialidad y, aunque su principal indicación la constituyen los tumores malignos de la cavidad oral y la orofaringe, también se utilizan ocasionalmente para tumores del espacio parafaríngeo.
Presentamos el caso de un paciente con un aneurisma carotídeo de localización muy alta, que planteaba diagnóstico diferencial con un paraganglioma vagal, no accesible a una cervicotomía convencional y que fue resecado mediante una abordaje transmandibular.
 
Método: Se realizó una manibulotomía lateral en escalón para acceder al espacio carotídeo y una vez comprobado el diagnóstico, una doble sección en el segmento craneal de la arteria carótida interna izquierda, excluyendo el tramo donde estaba el aneurisma, y a continuación un By-pass vascular con vena safena interna. Una vez comprobada la viabilidad del injerto se reconstruyó la mandíbulotomía con miniplacas de titanio y se dejó una sonda nasogástrica para alimentación durante 3 semanas.
Posteriormente se comprobó con una ortopantomografía la correcta alineación de las osteotomías.
 
Resultados: La deglución hubo de ser progresiva por manifestarse tras los primeros días un dolor al primer bocado que desapareció a las pocas semanas.
El paciente no presentó ninguna otra complicación.
Los estudios funcionales realizados hasta la fecha confirman la permeabilidad del injerto y la deglución es completamente normal sin limitación ni dolor a la apertura bucal.
Discusión: Se expone este caso a la consideración del creciente protagonismo del cirujano ORL en la cirugía cervicofacial y de la base del cráneo, y de la idoneidad de la actuación conjunta de diferente Especialidades en la resolución de problemas complejos de estas localizaciones.
Conclusiones: La actuación sinérgica con otros especialistas que también realizan cirugía en el área de cabeza y cuello ofrece óptimos resultados en el tratamiento quirúrgico de problemas complejos de esta localización.

Published: February 2023

Introducción y objetivo: La investigación y docencia en Cirugía se basa fundamentalmente en tres fuentes de conocimiento: el hombre enfermo, el cadáver (hueso temporal humano) y los simuladores quirúrgicos físicos o virtuales. La legislación y la ética limita el acceso a huesos temporales en nuestros Departamentos. Proponemos dos modelos costo-efectivos para entrenamiento, docencia e investigación de la cirugía de la cadena osicular, poniendo el foco en la cirugía de la otosclerosis.Método: Tras revisar la literatura, hemos entrenado en dos modelos experimentales de simulación quirúrgica de la cadena osicular: a) modelo experimental exvivo de oído medio de conejo b) modelo experimental exvivo ovino de oído medio.Resultados: Los modelos animales exvivo de oído medio de cordero y conejo (menos de 4 euros por pieza) son modelos quirúrgicos de muy bajo costo, con una anatomía del oído medio muy similar a la humana. En el conejo, la cadena osicular es muy pequeña, lo que hace compleja la cirugía. Las cadena osicular del cordero es de aproximadamente 2/3 el tamaño de la cadena humana, lo que hace más real la simulación de la técnica quirúrgica , aunque el tamaño 2/3 menor. Técnicamente la estapedectomía es más difícil en estos modelos animales que en humanos. El acceso a la cavidad de oído medio a través de la bulla es algo complicada y precisa fresado o escoplo en los primeros ejercicios. En cordero, el abordaje retroauricular consigue un acceso adecuado a la membrana timpánica y a la cadena.Discusión y Conclusiones: Los modelos exvivo de conejo y cordero ofrecen una alternativa costo-efectiva a los residentes y cirujanos otológicos jóvenes a los huesos temporales de cadáver humano para el entrenamiento de la cirugía de oído medio.
Neumoencéfalo espontáneo. A propósito de un caso.
Authors: Rodríguez-García Ana , Fernández-Cascón Sara , Pérez-González Rafael , Martín-Sigüenza Gerardo , Ramírez-Salas Jesús Eduardo , Álvarez-Álvarez Ignacio
Published: February 2023

Introducción y objetivo: El neumoencéfalo es la presencia de aire en cualquiera de los compartimentos intracraneales (intraventricular, intraparenquimatoso, subaracnoideo, subdural y epidural), generalmente se asocia con una pérdida de la continuidad ósea tras procedimientos quirúrgicos o traumatismos, siendo infrecuente su presentación sin factor desencadenante (2%). Mediante la presentación de un caso clínico, explicaremos las características fundamentales de dicha entidad y exposición de la bibliografía.

Método: Varón de 48 años que acude al Servicio de Urgencias tras cuadro de cefalea intensa de reciente aparición en hemicráneo derecho de cinco días de evolución que controló inicialmente con paracetamol, mostrando empeoramiento progresivo sin respuesta a analgesia; en este momento, presenta visión borrosa y cervicalgia. Se solicita TC craneal y ante hallazgos, se deriva el paciente al servicio de Otorrinolaringología y Neurocirugía.

Resultados: Neumoencéfalo localizado en región frontal izquierda y hoz cerebral, así como pequeñas burbujas en región occipital izquierda y en seno cavernoso derecho. Dehiscencia a nivel de la lámina cribosa del etmoides en fosa nasal izquierda. Ante estos hallazgos se realiza observación intrahospitalaria y tratamiento analgésico intravenoso durante dos semanas con evolución satisfactoria y se realiza nueva TC donde no se observa neumoencéfalo en parénquima cerebral, persistiendo la dehiscencia previamente descrita.

Discusión: La aparición del neumoencéfalo espontáneo suele ser secundario a un defecto en la continuidad ósea craneal, siendo una entidad muy rara (2%); la presencia de neumoencéfalo suele ocurrir tras una intervención quirúrgica, traumatismo craneofacial o tumores en base de cráneo. Como complicación podemos encontrar el neumoencéfalo a tensión, que se debe a la entrada de gas intracraneal que eleva la presión, produciendo un efecto válvula con la entrada de aire, pero no su salida, precisando tratamiento quirúrgico. Esta entidad se manifiesta clínicamente con cefalea, náuseas, vómitos e incluso convulsiones y alteraciones del estado neurológico. En su diagnóstico la técnica de elección sigue siendo la TC craneal. Cuando es un hallazgo casual se opta por un manejo conservador, resolviéndose de forma espontánea en unas dos semanas. Si presenta síntomas, fracturas de base del cráneo, o un defecto aéreo >15 mm se considera el tratamiento quirúrgico.

Conclusiones: Ante la clínica de cefalea con otros síntomas neurológicos asociados con mala respuesta a tratamiento analgésico, debemos incluir en el cuadro de diagnóstico diferencial el neumoencéfalo, sobre todo, ante la presencia de cirugías craneales o traumatismos previos. La resolución suele ser espontánea, pero debemos considerar la posibilidad de aparición de neumoencéfalo a tensión, por lo que es necesaria la vigilancia estrecha intrahospitalaria.

Published: February 2023

La mononucleosis infecciosa es una infección vírica originada comunmente por el Virus de Ebstein-Barr (VEB). La forma de presentación típica es la fiebre, la faringoamigdalitis, las adenopatías cervicales y la esplenomegalia. Sin embargo, en este póster queremos mostrar un síntoma de la enfermedad poco frecuente como es el edema palpebral conocido como signo de Hoagland. En algunas ocasiones puede ser el síntoma de presentación de la infección por eso es importante conocerlo y distinguirlo de otras entidades como la celulitis orbitaria, el angioedema, una reacción alérgica o el síndrome nefrótico.

Published: February 2023

Introducción y objetivo: El síndrome de Ramsay-Hunt  es una complicación poco frecuente de la afectación del ganglio geniculado por el VVZ causando parálisis facial periférica con afectación del conducto auditivo externo y membrana timpánica. En ocasiones puede afectar a pares craneales bajos al ser una neuritis periférica múltiple que puede afectar a los pares craneales VII, VIII, IX y X debido a sus relaciones de vecindad, a su origen embrionario común en el mismo arco branquial o por una afectación sanguínea a través de los vasos que los nutren.

Método: Mujer 93 años, que presenta lesiones ampollosas en pabellón auricular derecho de 4 días de evolución, con otorrea asociada. Disfagia para sólidos con odinofagia. Habiendo iniciado tratamiento antibiótico y antiviral sin mejoría clínica. Aparición súbita de parálisis facial derecha grado III (House Brackmann). A la exploración se objetivan lesiones costrosas con edema de pabellón auricular derecho, doloroso a la palpación, abundante secreción de CAE y membrana timpánica íntegra. Lesiones costrosas a nivel de párpado superior derecho y parálisis facial grado III derecha. En la nasofibroscopia se objetiva parálisis laríngea derecha con lesiones compatibles con Herpes Zóster. Se decide ingreso para tratamiento intravenoso y observación, con buena evolución.

Resultados: Herpes Zoster con parálisis  de VII y X par craneal.

Discusión: La peculiaridad del caso presentado reside en la asociación de un Síndrome de Ramsay-Hunt con una parálisis del nervio laríngeo recurrente.

Conclusiones: El síndrome de Ramsay-Hunt es una complicación poco frecuente de la afectación del ganglio geniculado por el VVZ. Puede presentarse bajo diversas formas clínicas que guardan en común la neuritis de pares craneales de forma muy diversa. Debemos tener en cuenta la posible asociación de parálisis de otros nervios craneales de cara a un correcto diagnóstico diferencial.

Authors: Guner Ekrem , Akkas Fatih , Ozdemir Osman , Arikan Yusuf , Seker Kamil Gokhan , Sam Emre
Published: February 2023

Priapism is a rare condition in the newborn. The aim of this study was to investigate the demographic, etiologic and clinical features of neonatal priapism. We retrospectively analysed the data of 11 patients diagnosed with neonatal priapism in the neonatal intensive care unit between 2000 and 2019. Priapism was defined as an erection in the neonatal period, lasting more than 4 hours. Etiological examinations revealed polycythemia in one (9.09%) patient, D-dimer elevation in three patients, and heterozygous methyltetrahydrofolate 667 gene mutations in one patient. Other patients were considered idiopathic. Detumescence was achieved in all 11 (100%) patients during the follow-up period. The median hospitalization duration was 6 (IQR [4, 8]; range, 2–9) days. The median follow-up duration was 38 (IQR [30, 42]; range, 13–94) months for patients followed-up in our hospital after discharge. Neonatal priapism is a rare condition. Successful treatment results can be achieved with conservative methods. Data acquired from our study showed that diseases with a tendency to hypercoagulation belong to the etiology by damaging penile microcirculation and make the response to conservative treatment more challenging.

Лик Украјине у српском роману друге половине 20 – почетка 21. века
Authors: Л. Билик Наталија
Published: February 2023

Traditionally, the basic qualities of imagology are associated with its key category—the literary ethnic character. A special field of imagological improvisations is the Serbian novel, which, according to well-known national experience and specific genre features, is favorable for ethnic panoramic imagological reactions, especially when it comes to the mid-20th – early 21st century. The aimof the research is to single out in chronological supposition the poetics of the literary presentation of the phenomenon of Ukraine in the Serbian novelistic discourse at the turn of the millennium. The research is based on comparative, comparative-typological, imagological methods in combination with approaches of structural-semantic and archetypal analysis. In the stated imagological perspective, the novels by I. Andrić, M. Crnjanski, M. Oljača, M. Selimović, G. Petrović, M. Prodanović and М. Pavić are analyzed. The works highlight semantic accents that emphasize the positive imagological view of Ukraine from its foreign ethnic reception, formed in genetically related – Serbian – literature, the tolerance of the Serbian people in creating subjective ethnic panoramas, indispensable for the evolutionary enrichment of intercultural communication based on epistemological heritage.
Полацк-Вільня-Масква… Паэтычныя і біяграфічныя вандроўкі Алега Мінкіна
Authors: Kowalow Siergiej
Published: February 2023

In the context of the ideas of geopoetics, the article examines the images of three cities—Polotsk, Vilnius, Moscow—in the work of the famous Belarusian poet Oleg Minkin. Poems from two poetic cycles are analyzed: Гарады (Cities) and Гастарбайт (Gastrbayt). Attention is drawn to such categories as biographical and cultural space, therapeutic landscape and nostalgic landscape, the influence of literary tradition on the image of the city and the influence of the cultural environment of the city on the national identity of the poet. In search of the genius loci of the three cities, Oleg Minkin portrays Polotsk as a city awakening its national identity, a space of hope, Vilnius as a harmonious space for life and, at the same time, a place of nostalgia for the former glory of the Grand Duchy of Lithuania, and Moscow as a new Babylon, a mixture of languages and peoples, a space of concentrated longing and nostalgia for the homeland.
Argumentative Exchange in Science: How Social Epistemology Brings Longino back down to Earth
Authors: Ajdari Emma Nyhof
Published: February 2023

In her account of scientific objectivity, feminist philosopher of science Helen Longino shows how scientific objectivity is not so much of individual practice, but rather a social commitment practiced by a scientific community, provided by the necessary accommodations for critical discourse. However, is this conception of scientific objectivity truly capable of living up to the social realities of critical discourse and deliberation within a scientific community? Drawing from Dutilh Novaes’ social epistemological account of argumentation, this paper highlights the challenges Longino’s scientific objectivity faces on a prescriptive and descriptive level, specifically in overcoming the various epistemic injustices Longino’s proposed structural accommodations for objectivity are still sensitive to. Dutilh Novaes’ social epistemological model of argumentation illustrates how the realities of critical debate too often don’t consist of true epistemic or knowledge exchange, even though such exchanges are essential to achieve Longino’s primary goal when redefining scientific objectivity: to wield out and address idiosyncratic background assumptions and individual bigotry that possibly influence a researcher’s scientific conduct.
Story Telling and Rhetorical You Concern in 2 Corinthians 8–9
Authors: Engberg-Pedersen Troels
Published: February 2023

The essay aims to show the structure and inner coherence of 2 Corinthians 8–9 by analyzing two features of the text that hold it intimately together: 1) Paul’s use of chronological narration in 8,1–7, 8,16–24, and 9,1–5 and 2) his focus on rhetorical ‘you concern’ (in a manner that is explained) in 8,9–15 and 9,6–15. In the latter context, it is argued against previous scholarship that Paul’s rhetorical concern differs quite strongly in 8,9–15 and 9,6–15. Throughout, it is argued that chapters 8–9 play an important role as part of Paul’s overall aim in the letter as a whole: to prepare for his own forthcoming visit to Corinth.
Using RNAi to Examine the Connection between Phenotype and Genotype in Caenorhabditis elegans to Enhance the Undergraduate Research Experience
Authors: Kitt Khameeka N.
Published: February 2023

Gene expression plays a pivotal role in the development, differentiation, and maintenance of organisms by allowing genes to encode for an observable trait (i.e., phenotype). To understand the function of a particular gene, several approaches can be taken, ranging from removing the gene entirely to targeting the product of the gene (i.e., the protein). RNA interference (RNAi) has been shown to be a powerful approach used to silence gene activity and examine the connection between DNA and protein along with controlling gene expression. The course-based undergraduate research experience (CURE) described in this article is a hands-on molecular biology lab–based lesson that allows students to examine the impact of RNAi on Caenorhabditis elegans reproduction and development through the examination of the central dogma of biology. Through these activities, students gain practice in the scientific method of inquiry by designing experiments to observe how genotype connects to phenotype and, subsequently, organism behavior.

Published: February 2023

In instructional settings, evolution and natural selection are challenging concepts to teach, due to the fact that these topics are difficult to observe in the laboratory or lecture hall. In the past few years, Avida-ED has emerged as an innovative tool for teaching evolutionary principles. It allows students to directly observe effects of evolution by changing different variables, such as environmental conditions and genetic sequences. In our study, we used pretest and posttest questionnaires to investigate the use of Avida-ED in undergraduate coursework. We showed that students demonstrated similar improvement in evolutionary understanding irrespective of major, undergraduate level, sex, or final end-of-course grade. These results reinforce the idea that Avida-ED can facilitate learning of evolution in all student populations.

This paper reviewed some of the applications of metamaterials in antenna design, cloaking devices, sensors and solar cells in brief. Metamaterials can be used as environment or as part of the antenna. Based on the required parameters, metamaterials while designing antennas are used in various types. They are highly useful in enhancing the power gain, bandwidth, in creating dense and antennas of multiple frequencies. Usage of metamaterial in antenna require proper designing of unit cell. This require creation of cells with special properties at required frequency. Cloaking is a technique of making specific objects invisible. This was achieved by isolating electromagnetic waves in that region. This paper reviewed some of the cloaking devices that use the technique of coordinate transformation and scattering cancellation. Metamaterial sensors which are more efficient than sensors with traditional materials are reviewed. These sensors exhibit enhanced sensitivity. Sensors used in wave guides and liquid chemical detection were reviewed. Solar cells that use metamaterials were reviewed. Usage of these materials reduce the loss in solar radiation making the solar cell more efficient based on the design. Recent design in solar cells concentrate on obtaining maximum reflection through usage of back reflectors and increased absorption

Nanofluids are possible heat transfer fluids with enhanced thermophysical characteristics and heat transfer performance for improved performance in many devices. The thermal behaviour of air conditioning systems using various nano-fluids is described in this study. The nano-fluid chosen for testing is CuO, ZnO and Al2O3, which are combined with the R22 refrigerants with a volume fraction of 0.1 %, 0.3 % and 0.5 % to analyse the airconditioning Performance. The magnetic stirrer is used to disperse nano-particles and ultrasound for approximately 4 hours, dispersing the specified quantity into compressed oil for 2 hours to the appropriate fraction. The model uses the fluid input information to predict fluid output temperatures, operating pressures, compressor power consumption and overall system output. The experimental results show an increase in performance by using 0.5 percent volume with R22base refrigerant when using CuO
