ABSTRACT Mantle cell lymphoma of the ocular and periorbital regions is extremely rare but should be considered in the differential diagnosis of lesions affecting the periorbital tissues. In this study, we present a rare case of mantle cell lymphoma of the lacrimal sac in a 65-year-old male presenting with a mass in the lacrimal sac region and epiphora. After clinical examinations and imaging studies, the mucocele was misdiagnosed. Considering the unexpected findings during external dacryocystorhinostomy, a frozen biopsy was performed, which confirmed the diagnosis of lymphoma. tissues study 65yearold yearold 65 year old epiphora studies misdiagnosed dacryocystorhinostomy performed 6

ABSTRACT Langerhans cell histiocytosis comprises a heterogeneous range of clinical manifestations secondary to clonal proliferation of histiocytes, characterized by the accumulation of these cells in various organs and tissues. The ophthalmological component commonly involved is the orbit. Herein, we report a rare case of Langerhans cell histiocytosis with eyelid involvement, which resulted in severe ocular surface complications, which subsequently significantly impacted the patient’s quality of life. This case report highlights the fact that despite being rare, Langerhans cell histiocytosis should be included in the differential diagnosis of eyelid lesions. Furthermore, a multidisciplinary approach with a systemic overview is crucial for managing the ocular complications. histiocytes tissues orbit Herein involvement complications patients patient s life lesions Furthermore

Abstract This study analyses “Lenguaje vulgar, familiar y folklórico de Chile y Nicaragua” (1928), a hidden comparative glossary published by Anselmo Fletes Bolaños in Revista chilena de Historia y Geografía. Firstly, the context and the biography of the author are presented, followed by a deep comparative study between the variety Chilean and Nicaraguan. Finally, the glossary is valued like a rare comparative material, which doesn’t have normative Spanish as a reference, but it is based on the comparison of two Latin American languages.

Resumen El presente artículo estudia el “Lenguaje vulgar, familiar y folklórico de Chile y Nicaragua” (1928), glosario escondido y comparativo publicado en la Revista chilena de Historia y Geografía por el nicaragüense Anselmo Fletes Bolaños. Tras describir el contexto del momento en el que se publica la obra, así como el periplo vital del autor y su relación con el folclorismo hispanoamericano, se examina el repertorio y se clasifican los lemas introducidos en función del grado de semejanza y disimilitud entre la variedad chilena y nicaragüense. Finalmente, se dota de valor al corpus estudiado, pues se considera un material comparativo poco común, que no tiene como referencia al español peninsular, sino que parte de la comparación de dos variedades lingüísticas hispanoamericanas.

Resumen: La vasculitis reumatoidea es una complicación sistémica y poco frecuente de la Artritis Reumatoidea. Si bien su incidencia ha descendido en los últimos años con el advenimiento de las nuevas terapias inmunosupresoras y biológicas, continua teniendo una alta morbimortalidad. Predomina en el sexo masculino, en pacientes seropositivos y con un largo período de la enfermedad establecida. Requiere de alta presunción diagnostica, siendo el compromiso cutáneo y nervioso periférico el más frecuente. La biopsia de nervio o piel es requerida habitualmente para su diagnóstico. El tratamiento se basa en corticoides e inmunosupresores. Presentamos tres casos clínicos y realizamos una revisión de la literatura.

Abstract: Rheumatoid vasculitis is a rare systemic complication of rheumatoid arthritis. Although its incidence has decreased in recent years with the advent of new immunosuppressive and biological therapies, it continues to have a high morbidity and mortality. It predominates in males, in seropositive patients and with a long period of established disease. It requires high diagnostic presumption, with skin and peripheral nervous involvement being the most affected. Nerve or skin biopsy is usually required for diagnosis. Treatment is based on corticosteroids and immunosuppressants. We present three clinical cases and carry out a review of the literature.

Predomina no sexo masculino, em pacientes soropositivos e com longo período de doença estabelecida. Exige alta presunção diagnóstica, sendo o envolvimento cutâneo e nervoso periférico os mais afetados. A biópsia de nervo ou pele geralmente é necessária para o diagnóstico. O tratamento é baseado em corticosteroides e imunossupressores. Apresentamos três casos clínicos e realizamos uma revisão da literatura.

Abstract: The aesthetic integration of solar systems with multi-family buildings remains rare in Latin American countries. This article considers sixty-five projects by architecture students in Lima (Peru) to establish compositional criteria using typological classifications of the solar system layout on the roofs, volumetric composition, and their relationship with façades and lower spaces. The results show a wide range of variables that must be resolved. However, there are limitations to understanding this integration when dealing with the inclination of roofs as well as the coherence and geometric arrangement in irregular configurations. More emphasis is required on understanding the interior organisation and its implications for solar systems when designing multi-family houses. Previous research on the quantification of solar incidence has already been published; however, more research for further aesthetic assessments in medium-density multi-family dwellings could be carried out in the future.

Resumen: La integración estética de sistemas solares en multifamiliares es un desafío todavía inédito en países latinoamericanos. Sesenta y cinco proyectos desarrollados por estudiantes de arquitectura en Lima (Perú) fueron considerados para establecer criterios de composición mediante clasificación tipológica a nivel de disposición de los sistemas fotovoltaicos, composición volumétrica, relación con las fachadas y los espacios inferiores. Los resultados demuestran múltiples posibilidades. Sin embargo, existen limitaciones para entender esta integración cuando se trata de la inclinación de los techos, así como la coherencia y la disposición geométrica en las configuraciones irregulares obtenidas. Tratándose de multifamiliares y debiendo lidiar con aspectos técnicos, se requiere mayor énfasis en la comprensión de la organización interior y sus implicancias con los sistemas solares. Una investigación previa relacionada a la cuantificación de la incidencia solar ha sido ya publicada, sin embargo, investigaciones para mayores evaluaciones estéticas en multifamiliares de media densidad podrían realizarse a futuro.

Resumo: A doença de von Willebrand adquirida (EVW acq, AVWS) é um distúrbio hemorrágico adquirido raro com características clínicas e laboratoriais semelhantes à doença de von Willebrand congênita. Associado a doenças hemato-oncológicas, autoimunes, cardiovasculares e tumores sólidos. As gamopatias monoclonais constituem um grupo heterogêneo de distúrbios caracterizados pela proliferação de linfócitos B nos últimos estágios de maturação ou plasmócitos que preservam a capacidade de produzir uma imunoglobulina monoclonal (Ig) ou um de seus componentes. Como consequência, ocorre o aparecimento de uma paraproteína ou componente M (CM) no soro e/ou na urina, que serão formados pela mesma cadeia pesada ou leve, e por regiões variáveis idênticas. Apresentamos o caso de uma mulher de 57 anos, que apresentava um síndroma hemorrágico, alteração da crase na sua via intrínseca, onde é diagnosticada Doença de Von Willebrand Adquirida secundária a Mieloma Múltiplo. O tratamento visava estancar o sangramento, prevenir complicações e abordar prontamente a patologia hemato-oncológica subjacente. Para sua abordagem, exigiu a realização de plasmaférese terapêutica que teve papel de ação terapêutica precoce e efetiva com excelente tolerância. Diante do diagnóstico, rapidamente foi iniciada poliquimioterapia, sendo este paciente candidato a transplante de células-tronco hematopoiéticas. O objetivo da apresentação deste caso clínico é realçar a importância de um diagnóstico correto e atempado face à suspeita clínica de uma coagulopatia secundária a uma doença hemato-oncológica subjacente. Portanto, enfatizamos a abordagem multidisciplinar.

Asociándose con enfermedades hemato-oncológicas, autoinmunes, cardiovasculares y tumores sólidos. Las gammapatías monoclonales constituyen un grupo heterogéneo de trastornos caracterizados por la proliferación de linfocitos B en los últimos estadios madurativos o células plasmáticas que preservan la capacidad de producir una inmunoglobulina (Ig) monoclonal o alguno de sus componentes. Como consecuencia, se produce la aparición de una paraproteína o componente M (CM) en suero y/o orina que estará formado por la misma cadena pesada o ligera, y por regiones variables idénticas. Se presenta el caso de una mujer de 57 años, que se presenta con un síndrome hemorragíparo, alteración de la crasis en su vía intrínseca, donde se diagnostica EVW adq secundaria a Mieloma Múltiple (MM) con CM IgM 5,9 g/dl. El tratamiento tuvo como objetivos detener el sangrado, prevenir complicaciones y abordar precozmente la patología hemato-oncológica causante. Para su abordaje requirió la realización de recambios plasmáticos terapéuticos (RPT) que tuvieron un rol de acción terapéutica temprana y eficaz con excelente tolerancia. Ante el diagnóstico se inició rápidamente poliquimioterapia siendo ésta una paciente candidata a trasplante de progenitores hematopoyéticos. El objetivo de la presentación de este caso clínico es destacar la importancia de un correcto y oportuno diagnóstico ante la sospecha clínica de una coagulopatía secundaria a una enfermedad hemato-oncológica subyacente. Por lo que hacemos énfasis en el abordaje multidisciplinario.

Abstract: Acquired von Willebrand disease (AVWS) is a rare acquired bleeding disorder with clinical and laboratory features similar to congenital von Willebrand disease. Associated with hemato-oncological, autoimmune, cardiovascular diseases and solid tumors. Monoclonal gammopathies constitute a heterogeneous group of disorders characterized by the proliferation of B lymphocytes in the last stages of maturation or plasma cells that preserve the capacity to produce a monoclonal immunoglobulin (Ig) or one of its components. As a consequence, the appearance of a paraprotein or M component (CM) occurs in serum and/or urine, which will be formed by the same heavy or light chain, and by identical variable regions. We present the case of a 57-year-old woman, who presented with a hemorrhagic parous syndrome, alteration of the crasis in its intrinsic way, where Acquired Von Willebrand Disease secondary to Multiple Myeloma is diagnosed. Treatment was aimed at stopping the bleeding, preventing complications, and promptly addressing the underlying hemato-oncological pathology. For its approach, it required the performance of therapeutic plasma exchanges that had a role of early and effective therapeutic action with excellent tolerance. Given the diagnosis, polychemotherapy was quickly started, this patient being a candidate for hematopoietic stem cell transplantation. The objective of presenting this clinical case is to highlight the importance of a correct and timely diagnosis in the face of clinical suspicion of a coagulopathy secondary to an underlying hemato-oncological disease. Therefore, we emphasize the multidisciplinary approach.

Resumen Descripción del caso: Paciente de 23 años con hemorragia abdominal de origen no claro, que posteriormente presenta inestabilidad hemodinámica, requiriendo manejo quirúrgico en tres ocasiones con evolución satisfactoria. Hallazgos clínicos: Presentó sangrado cuantificado de 5500 cc en cavidad abdominal (grado IV - clasificación ATLS) con lesiones hepáticas en los segmentos I, IV y VIII, sin hallazgos sugestivos de trauma al examen físico, ni otros hallazgos traumáticos internos. Tratamiento y resultados: Se llevó a cabo una intervención quirúrgica precoz mediante laparotomía exploratoria con hallazgos ya descritos, además de dos tiempos quirúrgicos adicionales que llevaron al control del sangrado, con evolución satisfactoria. Relevancia clínica: El sangrado abdominal y laceración de víscera sólida secundario a trauma cerrado de abdomen es una etiología común en pacientes jóvenes masculinos, siendo contrario a esta afirmación el sangrado de origen hepático sin trauma es una etiología poco común. El presente caso resulta ser una dificultad diagnóstica en cuanto a la etiología, ya que lo evidenciado en la exploración quirúrgica no concuerda con el examen físico externo, sin una historia clínica clara al ingreso se deja la interrogante de la causa.

Summary: Case description: 23-year-old patient with abdominal hemorrhage of unclear origin, who subsequently presented hemodynamic instability, requiring surgical management on three occasions with satisfactory evolution. Clinical findings: she presented quantified bleeding of 5500 cc in the abdominal cavity (grade IV-ATLS classification) with liver lesions in segments I, IV and VIII, without findings suggestive of trauma on physical examination, or other internal traumatic findings. Treatment and results: An early surgical intervention was carried out through exploratory laparotomy with findings already described, in addition to two additional surgical procedures that led to control of bleeding, with satisfactory evolution. Clinical relevance: Abdominal bleeding and solid viscus laceration secondary to blunt abdominal trauma is a common etiology in young male patients, contrary to this statement, bleeding of hepatic origin without trauma is a rare etiology. The present case turns out to be a diagnostic difficulty in terms of etiology, since what was evidenced in the surgical exploration does not agree with the external physical examination, without a clear clinical history at admission, the question of the cause is left.

Resumen La incorporación de nuevas tecnologías, como ultrasonido, J-Plasma (plasma de helio) y el Microaire (vibroliposucción), ha facilitado los procedimientos de lipoescultura consiguiendo una mayor satisfacción del paciente. Los beneficios de estas tecnologías se acompañan de bajas complicaciones reportadas; el presente caso constituye la cuarta descripción de neumomediastino secundario a la utilización de Renuvion® (J-Plasma) posterior a la extracción de grasa en brazos y muslos por medio de liposucción; esta infrecuente complicación se debe considerar diagnóstico diferencial en el estudio de presentación clínica de disnea y enfisema subcutáneo durante el posoperatorio.

Abstract The incorporation of new technologies such as ultrasound, J-Plasma (helium plasma) and MicroAire (power assited liposuction) has facilitated liposculpture procedures, resulting in greater patient satisfaction. The benefits of these technologies are accompanied by low reported complications; this case is the fourth description of pneumomediastinum secondary to the use of Renuvion® (J-Plasma) after liposuction for fat removal in the arms and thighs. This rare complication should be considered as part of the differential diagnosis during the study of clinical dyspnea and subcutaneous emphysema in the postoperative period.

Abstract Hailey-Hailey disease is a rare genodermatosis described in 1939, with an autosomal dominant inheritance pattern, characterized by compromised adhesion between epidermal keratinocytes. It has an estimated prevalence of 1/50,000, with no gender or race predilection. It results from a heterozygous mutation in the ATP2C1 gene, which encodes the transmembrane protein hSPA1C, present in all tissues, with preferential expression in keratinocytes. Mutations in the ATP2C1 gene cause changes in the synthesis of junctional proteins, leading to acantholysis. It usually begins in adulthood, with isolated cases at the extremes of life. It manifests as vesico-bullous lesions mainly in the flexural areas, which develop into erosions and crusts. Chronic lesions may form vegetative or verrucous plaques. Pruritus, a burning feeling and pain are common. It evolves with periods of remission and exacerbation, generally triggered by humidity, friction, heat, trauma and secondary infections. The diagnosis is based on clinical and histopathological criteria: marked suprabasal acantholysis, loosely joined keratinocytes, giving the appearance of a “dilapidated brick wall”, with a few dyskeratotic cells. The acantholysis affects the epidermis and spares the adnexal epithelia, which helps in the differential diagnosis with pemphigus vulgaris. Direct immunofluorescence is negative. The main differential diagnoses are Darier disease, pemphigus vegetans, intertrigo, contact dermatitis, and inverse psoriasis. There is no cure and the treatment is challenging, including measures to control heat, sweat and friction, topical medications (corticosteroids, calcineurin inhibitors, antibiotics), systemic medications (antibiotics, corticosteroids, immunosuppressants, retinoids and immunobiologicals) and procedures such as botulinum toxin, laser and surgery. There is a lack of controlled clinical trials to support the choice of the best treatment.

Abstract Introduction Eagle syndrome is a rare and an often misdiagnosed entity in otorhinolaryngology. Objective To determine the efficacy of the surgical treatment for Eagle syndrome. Methods The present prospective study included 25 patients who presented with complaints of pain in the throat, ear, and neck, as well as difficulty and/or pain while swallowing; they were assessed for Eagle syndrome. As per patient profile, we performed a clinical assessments along with orthopantomograms (OPGs), three-dimensional computed tomography (3D CT) scans, and cone beam computed tomography (CBCT). Pain was assessed pre- and postoperatively through the Numerical Rating Scale-11 (NRS-11), whose score ranges from 0 to 10. Microscopic tonsillo-styloidectomy was performed in cases in which the conservative treatment failed to relieve pain. Results The mean age of the entire study population was of 36.08 ± 7.19 years, and the male-to-female ratio was of 1.08:1. Referred otalgia was the commonest (44%) complaint. Radiologically, out of 25 patients, 20 patients presented elongated styloid processes. The longest symptomatic styloid process measured radiographically was of 64.7 mm while the shortest was of 28.2 mm. Out of 20 patients, 12 underwent surgery. The postoperative pain assessment through the NRS-11 was performed on day 0 (3.83 ± 0.83), day 7 (1.5 ± 0.52), week 4 (0.5 ± 0.52), and week 12 (0.41 ± 0.51). By 12 weeks, 7 patients were symptom-free, while 5 patients still reported mild pain. Conclusion Eagle syndrome associated with an elongated styloid process is not a rarity, but it often goes undiagnosed. Microscopic tonsillo-styloidectomy shows excellent results in the management of patients with Eagle syndrome. otorhinolaryngology 2 throat ear neck andor or swallowing profile OPGs, OPGs , (OPGs) threedimensional three dimensional 3D D CT scans CBCT.

Abstract Introduction Submandibular gland fistula (SGF) is a rare subset of salivary gland fistulas. It is seldom tough to diagnose them prior to surgical exploration, and it is often clinically confused with close differentials. An early diagnosis based on pertinent clinical features and focused radiological findings can be pivotal in optimal management and help prevent recurrence and avoid unnecessary investigations/interventions. Objective To review articles that discuss SGF and provide vital etiological, clinical, and imaging features of this rare entity that can aid in early clinical diagnosis. Data Synthesis An extensive review involving PubMed and Google Scholar and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Conclusion Submandibular gland fistula is a rare entity. It can be confused with close differentials, including branchial fistulas, if not thoroughly examined. Discharge from fistulae along with submandibular pain/tenderness and/or swelling are important diagnostic clues. A history of trauma, nodule at the site of discharge, prior submandibular disease/calculi, or discharge aggravated with food further increases a clinical suspicion. Optimal radiological investigation looking for calculi/foreign body and delineating the fistula tract is vital to affirm a diagnosis. Gland with fistula excision is a commonly advocated treatment of choice with no reports of recurrence, although conservative management and gland preserving surgery have also reported a favorable prognosis.

Abstract This article analyzes the social, family, and country relations between a Zapotec community on the Isthmus of Tehuantepec and the main cities where they emigrate to pursue higher education. At the same time, it shows the transformations in gender relations that have arisen because of these migratory processes for educational purposes. This work is part of a long-term investigation on the topic, carried out initially for my bachelor's and master's thesis and later as part of the development of my doctoral thesis from 2009 to 2013. Likewise, in the intermittent research that I have carried out to date, the results are expressed in various articles and book chapters. It is part of the studies of the anthropology of education and is based on the analytical perspective proposed by María Bertely (1997, 1998, 2004, 2019) on schooling processes, ethnogenesis, de facto autonomy, and synchronic/diachronic approach to understanding how micro and community processes, apparently isolated in time, are connected to structural, macro-social, global, and long-term processes, such as school, in its broadest sense. The methodology is based on the use of genealogy, ethnography, interviews, and participant observation as classic tools of anthropology. Among the results, we find that access to the school system, and specifically to higher education, serves as a tool for obtaining, manipulating, and preserving ethnic citizenship; for the transformation of ethnic and gender identities; and the formation of strategic alliances with the nation-state and its government policies. In that sense, the work represents an original study, analyzing the cases of Zapotec literate families of the middle and upper class, rare in Mexican anthropology. However, we will see that having class privileges does not exempt Zapotecs from experiencing racism, discrimination, and gender inequalities in the context of migration.

Resumen Este artículo analiza las relaciones sociales, familiares y de paisanaje entre una comunidad zapoteca del Istmo de Tehuantepec y las principales ciudades a donde emigran para escolarizarse a nivel superior. Al mismo tiempo, muestra las transformaciones en las relaciones de género que se han suscitado como resultado de estos procesos migratorios con fines educativos. Este trabajo se enmarca en una investigación de largo aliento sobre el tema, realizada en un primer momento, para mi tesis de licenciatura y maestría, y posteriormente para el desarrollo de mi tesis doctoral del año 2009 al año 2013. Asimismo, en las investigaciones intermitentes que he llevado a cabo hasta la fecha, cuyos resultados se expresan en diversos artículos y capítulos de libro. Se inscribe dentro de los estudios de la antropología de la educación y se fundamenta en la perspectiva de análisis propuesta por María Bertely (1997, 1998, 2004, 2019) sobre procesos de escolarización, etnogénesis, autonomía de facto, y enfoque sincrónico/diacrónico, para entender cómo procesos micro y comunitarios, aparentemente aislados en el tiempo, se conectan a procesos estructurales, macrosociales, de carácter global y de largo aliento, como es la escuela, en su sentido más amplio. La metodología está basada en el uso de la genealogía, la etnografía, la entrevista y la observación participante como herramientas clásicas de la antropología. Entre los resultados encontramos que el acceso al dispositivo escolar, y específicamente a la educación superior, funge como herramienta para la obtención, manipulación y preservación de la ciudadanía étnica; para la transformación de las identidades étnicas y genéricas; y la formación de alianzas estratégicas con el Estado-nación y sus políticas gubernamentales. En ese sentido, el trabajo representa un estudio original, al analizar los casos de las familias letradas zapotecas de clase media y alta, escasos en la antropología mexicana. No obstante, veremos que contar con privilegios de clase no exime a los zapotecos de experimentar racismo, discriminación y desigualdades de género en los contextos de la migración.

Abstract A series of cases is reported of women in whom, after an esthetic procedure of injection of biopolymers into the buttocks, they present complications due to the extensive migration (and spreading) of these and post-surgical complications secondary to the extraction of the exogenous material. Although the complications of biopolymers are more common over time, they are rare cases and have few reports in the literature. More and more late effects of iatrogenic allogenosis are seen, and it becomes a topic of medical interest to recognize the main radiological findings associated with biopolymers, which awakens the need to report cases, recognize their complications, and carry out a review of the literature to update and thus improve the outcomes, the quality of life, and the long-term side effects.

Resumen Se reporta una serie de casos de mujeres en quienes posterior a un procedimiento estético de inyección de biopolímeros en los glúteos, presentan complicaciones dadas por la diseminación extensa de estos y posquirúrgicas secundarias a la extracción del material exógeno. Aunque las complicaciones de los biopolímeros son más comunes en el tiempo, son casos infrecuentes y con pocos reportes en la literatura. Cada vez se ven más efectos tardíos de la alogenosis iatrogénica y se convierte en un tema de interés médico reconocer los principales hallazgos radiológicos asociados a los biopolímeros, el cual despierta la necesidad de reportar casos, reconocer sus complicaciones y hacer una revisión de la literatura con el fin de actualizarse y de esta forma mejorar en los desenlaces, en la calidad de vida y en las secuelas a larga plazo.
