Programa pedagógico tradicional de la parasitología humana o médica / Traditional educational program of human or medical parasitology

RESUMEN Es fundamental la enseñanza de la parasitología humana para los estudiantes de las carreras de ciencias de la salud, especialmente la médica, por ser un importante problema de salud pública con distribución mundial, con alta frecuencia en países de bajos recursos económicos y por su presencia en aquellos países considerados desarrollados. En este sentido, se estima que existen en el mundo 2800 millones de individuos infectados con geohelmintos, 20 % a 30 % de infectados con Toxoplasma gondii, 300 a 500 millones de casos nuevos de malaria al año y aproximadamente 15 millones de latinoamericanos con enfermedad de Chagas, una enfermedad causada por el Trypanosoma cruzi. En este artículo de revisión narrativa se analiza información disponible en repositorios digitales sobre aspectos del programa pedagógico tradicional de la parasitología humana o médica, para lo cual se emplearon descriptores o palabras clave en estrecha relación con el tema. Los artículos que se revisaron principalmente fueron aquellos publicados en revistas científicas arbitradas, indexadas y de reconocido prestigio. Asimismo, se describen el programa tradicional de parasitología y la pedagogía prevalente empleada, con el propósito de fomentar el debate sobre los métodos que conducen a su aprendizaje. Por otro lado, si se consideran el carácter dinámico que posee este proceso y los constantes desafíos que deben afrontarse en este campo, esta información puede ayudar a explorar nuevas formas de enseñar la parasitología en respuesta a las exigencias del contexto. En conclusión, las enfermedades parasitarias han afectado a la humanidad a lo largo de la historia, y han causado enfermedades, discapacidad y la muerte de millones de personas. Por tanto, entre las medidas para combatir tan terrible flagelo se señala la capacitación de más y mejores profesionales en el área, por su papel preponderante en el diseño y ejecución de los programas de control, de lo que se desprende la necesidad de describir en detalle las características de la enseñanza tradicional de esta rama del conocimiento ―como se muestra en el contenido de este escrito― en virtud de la existencia de nuevos métodos de enseñanza humana: la enseñanza participativa, aprendizaje basado en problemas y aprendizaje asistido por internet.

ABSTRACT The teaching of human parasitology is essential for students of health sciences, especially medicine, because it is a major global public health problem―occurring with high frequency in low-income countries―and because of its presence in countries considered developed. In this sense, it is estimated that worldwide there are 2,800 million individuals infected with soil-transmitted helminths, 20 to 30% people infected with Toxoplasma gondii, 300 to 500 million new cases of malaria per year, and nearly 15 million Latin Americans with Chagas disease, an infection caused by Trypanosoma cruzi. This narrative review article analyzes information available in digital repositories on aspects of the traditional educational program of human or medical parasitology using descriptors or keywords closely related to the topic. The reviewed articles were mainly those published in peer-reviewed, indexed and prestigious scientific journals. Moreover, the traditional program of parasitology and the prevailing pedagogy are described with the purpose of encouraging discussion on the methods that lead to its learning. Also, given the dynamic nature of this process and the constant challenges that must be faced in this field, said information can help to explore new ways of teaching parasitology in answer to the demands of the context. In conclusion, parasitic diseases have affected humankind throughout history, causing illness, disability and death in millions of people. Therefore, among the measures to fight such a terrible scourge, the training of more and better professionals in the area is promoted due to their leading role in the design and execution of control programs. As a result, the need to describe in detail the characteristics of the traditional teaching of this branch of knowledge arises―as shown in this paper―in view of the new human teaching methods: participatory learning, problem-based learning and Internetassisted learning.

Thinking on ideological and political education in Medical Parasitology teaching / 中国血吸虫病防治杂志

With the deepening reform of ideological and political education, Medical Parasitology teaching needs to update the teaching concept, change the teaching ideas, as well as keep trying to combine ideological and political education with the curriculum content closely. In addition to teaching students’ basic knowledge and practical skills, teachers are needed to cultivate their moral literacy and political awareness through course teaching, so as to provide the basis for students’ subsequent adaptations to social environments and jobs. Currently, the study of ideological and political education in Medical Parasitology teaching is still in the exploratory stage. Therefore, colleges and universities need to carry out effective construction of ideological and political education in Medical Parasitology teaching, in order to achieve good teaching outcomes and provide insights into ideological and political education in teaching.

Toxoplasmosis outbreak in São Paulo, Brazil: Epidemiology and visual outcome

ABSTRACT Purpose: To describe a 2019 acute toxoplasmosis outbreak in the city of São Paulo, Brazil, and to evaluate the laboratory serological profile for toxoplasmosis for three consecutive years. The ophthalmological manifestations of the patients involved in the outbreak were also studied. Methods: A cross-sectional descriptive study of a toxoplasmosis outbreak in São Paulo, Brazil, between February and May 2019. Epidemiological data were described, as were the observed ocular manifestations. As part of this study the number of patients with positive IgM toxoplasmosis serology was obtained from a large laboratory network (DASA) for three consecutive years, including the year of the outbreak (2018, 2019, 2020). Results: Eighty-three individuals were identified in the outbreak and two clusters were studied. The clinical picture of at least 77% of the patients, the epidemiological analysis, and the short incubation period (5-8 days) suggested contamination by oocysts. Serological laboratory data analysis revealed an increase of positive toxoplasmosis IgM in 2019 of 73% compared to the previous year. Ophthalmological examination revealed that at least 4.8% of the patients developed toxoplasmic retinochoroiditis, none of whom had been treated during the acute systemic disease. Conclusion: Our findings indicate vegetable contamination as the possible source of this outbreak, a high prevalence of toxoplasmosis in São Paulo during the outbreak period, and a drop in the number of tests during the COVID-19 pandemic. Retinochoroiditis was observed in at least 4.8% of the cases. We confirm the need to implement effective means for the prevention, diagnosis, and treatment of the disease. This may involve raising awareness among the population of the importance of vegetable hygiene, and improved quality control of food and water.

Manejo de la estrongiloidiasis: revisión de la literatura con enfoque en la epidemiología en Bolivia

La estrongiloidiasis es una de las enfermedades parasitarias más desatendidas. Tiene una elevada morbilidad y mortalidad en personas tratadas con corticosteroides o con una inmunidad reducida por otros motivos. En Bolivia los estudios realizados han demostrado una alta prevalencia y su transmisión en diversas regiones tropicales y de los valles interandinos. Aunque la enfermedad no se transmite en climas fríos, todas las regiones de Bolivia pueden verse afectadas debido a la migración interna de la población. Las personas pueden infectarse al viajar a regiones endémicas décadas antes de presentar síntomas, porque si se deja sin tratar, puede persistir de por vida La baja sensibilidad de las pruebas diagnósticas coproparasitológicas utilizadas de rutina dificultan su diagnóstico, pero existen técnicas de diagnóstico más eficientes a bajo costo como la técnica de Baermann modificada. La ivermectina es el tratamiento de elección, muy eficaz, bien tolerado cuando es prescrito a dosis adecuada, accesible y disponible en Bolivia.

Strongyloidiasis is one of the neglected parasitosis. Strongyloidiasis has a high morbidity and mortality among people treated with corticosteroids or with reduced immunity for other reasons. In Bolivia, the studies have shown its transmission and high prevalence in various tropical regions and the inter-Andean valleys. Although the disease is not transmitted in cold climates, people living in all regions of Bolivia can be affected due to internal migration. Infection can occur during travel to endemic areas decades before the onset of symptoms, because if left untreated, the strongyloidiasis can persist for life. This disease is one of the most neglected mainly due to the low sensitivity of the coproparasitological tests routinely used in clinical laboratories. There are more efficient diagnostic methods, such as the modified Baermann technique. which can be applied in Bolivia at low cost. Ivermectin is the treatment of choice, effective, well tolerated in adequate dosis, cheap and available in Bolivia.

Treatment of oral myiasis in a patient with implant-supported fixed prosthesis

ABSTRACT Oral myiasis is a rare parasitic disease that requires immediate treatment once diagnosed. However, no standard treatment protocol can be found in the literature. Through a clinical-surgical report, we present the case of an 82-year-old man with lesions extending through the vestibule and alveolar ridge of the maxilla on both sides, in addition to occupying a large part of the palate, with a considerable number of larvae. The patient was initially treated with a single dose of systemic ivermectin (6 mg orally) and topical application of a tampon soaked in ether. The larvae were then surgically removed and debridement of the wound was performed. A crushed tablet of ivermectin 6 mg was applied topically for 2 days, the remaining larvae were again mechanically removed, and the patient received intravenous antimicrobial therapy. Treatment with systemic and topical ivermectin combined with antibiotic therapy and debridement proved to be effective in treating oral myiasis.

Teaching of Veterinary Parasitology to University students in Trinidad, West Indies; are our local wildlife species neglected? / Ensino de parasitologia veterinária para estudantes universitários em Trinidad, Índias Ocidentais; nossas espécies selvagens locais são negligenciadas?

Abstract Parasites of veterinary importance have been heavily focused on domesticated livestock that was introduced into the neo-tropics. The text used in the teaching parasitology to veterinary students in Trinidad has only investigated the parasites of domesticated species. In the reviewed veterinary parasitology text no mention was made on the parasites that affect wild neo-tropical animals. Information on wild neo-tropical animals had to be sourced from texts on the management of wild life animals in the Neotropics. The texts that were reviewed in this document spanned from the mid-1950s to 2020. The information presented in this review reveals the exhaustive work done on the parasites of domesticated species but also revealed little information on neo-tropical animals with the potential for domestication. In conclusion, this review reveals the gap of information that is missing from parasitology texts used in the teaching of veterinary students. In the future these parasitology texts can be revised to include chapters on the parasites of neo-tropical animals with the potential for domestication. At present students that graduate from the veterinary parasitology course has little information on the parasites of animals which are present in their 'backyards'.

Exploration and practice of process assessment in Human Parasitology teaching for international medical students / 中国血吸虫病防治杂志

Teaching evaluation is an important measure to test the teaching quality. In order to better achieve the training objectives among international medical students based on the specific conditions of foreign students and the characteristics of Human Parasitology, a process-based assessment and evaluation system has been established for international medical students. The process assessment highlights the characteristics of assessment process, diversified forms and inquires of test questions. Following implementation of process assessment, the proportion of excellence (examination scores of 90 and higher) improved from 3.25% (10/308) to 13.09% (50/382) (t = 5.995, P < 0.001) and the proportion of good marks (examination scores of 80 to 89) increased from 18.83% (58/308) to 36.13% (138/382) (t = 7.505, P < 0.001) during the semester assessment among international medical students at five grades, while the proportion of failure in examination pass (examination scores of below 60) reduced from 12.34% (38/308) to 3.24% (10/382) (t = 7.303, P < 0.000 1), indicating that the process-based assessment and evaluation system improves the examination score of Human Parasitology among international medical students and the teaching quality of Human Parasitology.

Conocimiento de los costarricenses sobre parasitosis en la población infantil / Knowledge of Costa Ricans about parasitosis in children population / Conhecimento dos costarriquenhos sobre parasitoses na população infantil

Objetivo: los parásitos son organismos que viven en el interior o sobre otra especie para su propio beneficio. Logran afectar plantas, animales y humanos. Los niños son más vulnerables a infectarse, pero la incidencia ha disminuido en Costa Rica gracias a la mejora en salubridad. El objetivo de este estudio fue evaluar el conocimiento general que tiene la población costarricense con respecto a las parasitosis infantiles. Metodología: se realizó un estudio observacional, descriptivo de tipo transversal, a una muestra de 196 sujetos. Se presentó encuesta a costarricenses mayores de 18 años que tuvieran un dispositivo con acceso a internet. Se consultó sobre el conocimiento del cuadro clínico de las parasitosis infantiles en Costa Rica. Resultados: la mayoría de los participantes eran universitarios (68.3%). El 89.9% cree que los parásitos de las mascotas pueden infectar a los humanos. Los parásitos más conocidos fueron los piojos 173 (88.3%). La parte del cuerpo que se considera más afectada por los parásitos es el estómago (75.5%). La principal medida preventiva contra las parasitosis más conocidas es lavarse las manos (67.9%). Conclusión: muchos participantes creen que los humanos se pueden infectar por los mismos parásitos de los animales. Los piojos fueron los parásitos más conocidos y las garrapatas las menos conocidas. La mayoría considera el vómito o la diarrea como los síntomas principales de las parasitosis y creen que el estómago es el más afectado en una infección. Además, señalan que la principal medida preventiva para evitar el contagio es el lavado de manos.

Objective: parasites are organisms that live inside or on another species for their own benefit, managing to affect plants, animals, and humans. Children are more vulnerable to infection, but the incidence has decreased thanks to the improvement in Costa Rican sanitation. The aim was to evaluate the general knowledge that the Costa Rican population has regarding childhood parasitosis. Methodology: an observational, descriptive, cross-sectional study was carried out on a sample of 196 subjects. A survey was conducted among Costa Ricans over 18 years of age who had a device with internet access. The participants were asked about their knowledge on the clinical picture of childhood parasitosis in Costa Rica. Results: most of the participants were college students (68.3%). 89.9% of them believe that pet parasites can infect humans. The best-known parasites were lice, marked by 173 (88.3%) people. The stomach is the part of the body considered most affected, with 148 (75.5%) responses. The main known preventive measure is washing hands with soap and water, answered by 133 participants (67.9%). Conclusion: Many participants believe that humans can be infected by the same parasites as animals. Lice were the best known and ticks the least. Most of the people consider vomiting and/or diarrhea as one of the main symptoms and believe that the stomach is the most affected part during the infection. In addition, they consider that the main preventive measure to avoid contagion is hand washing.

Análisis comparativo de evaluaciones de parasitología / Comparative analysis of parasitology evaluations

El cambio curricular es un proceso de transformaciones que expresa las modificaciones operadas en la sociedad en términos epidemiológicos, frente a la emergencia y reemergencia de parasitosis, en estrecha relación con la geografía médica y los condicionamientos sociales, económicos y políticos bajo los que se desarrolla la sociedad; por tanto, reconocer y tratar los principales parásitos que afectan al hombre y las enfermedades parasitarias asociadas a ellos resulta esencial para la formación médica de estos tiempos. La presente investigación tiene como objetivo comparar los resultados en las calificaciones en el examen de parasitología del 9no semestre de dos de las universidades públicas de la provincia del Guayas, Ecuador, en el periodo de noviembre de 2020. Se realizó un estudio exploratorio/descriptivo de la variable "Evaluación", que contuvo medidas de posición, dispersión y contraste de la normalidad, y el desempeño fue determinado mediante las listas de apreciación de competencias, establecido como instrumento de evaluación. De igual forma, se utilizó la técnica estadística de comparación de medias a través de la Prueba t para muestras independientes con un nivel de significancia del (5%). Los datos fueron procesados empleando el Programa Estadístico para Ciencias Sociales (SPSS v25). Concluyendo, que los estudiantes de la universidad de ESPOL tuvieron mejor puntuación en relación con la media, y menos dispersión en sus resultados con respecto a la UG. En líneas generales la mayoría de los estudiantes obtuvieron un alto desempeño de las competencias, siendo fundamental la constancia en la mejora del proceso de enseñanza de la parasitología(AU)

Curriculum change is a transformation process that expresses the changes that have taken place in society in epidemiological terms, in the face of the emergence and re-emergence of parasites, in close relation to the medical geography and the social, economic and political conditions under which society develops; therefore, recognizing and treating the main parasites that affect man and the parasitic diseases associated with them is essential for medical training in these times. The objective of this research is to compare the results in the qualifications in the parasitology exam of the 9th semester of two of the public universities of the province of Guayas, Ecuador, in the period of November 2020. An exploratory/descriptive study of the variable "Evaluation", which contained measures of position, dispersion and contrast of normality, and performance, was determined through the competency assessment lists, established as an evaluation instrument. Similarly, the statistical technique of comparison of means was used through the t-test for independent samples with a significance level of (5%). The data was processed using the Statistical Program for Social Sciences (SPSS v25). Concluding, that the students of the ESPOL University had a better score in relation to the average, and less dispersion in their results with respect to the UG. In general terms, most of the students obtained a high performance of the competences, being fundamental the constancy in the improvement of the parasitology teaching process(AU)

The transmission of visceral leishmaniasis in the municipality of Guarujá, on the Coast of São Paulo state, Brazil

ABSTRACT OBJECTIVE To perform an entomological survey, evaluating the circulation of Leishmania spp. in sand flies captured from the new foci of visceral leishmaniasis (VL) in the coastal region of São Paulo state. METHODS Sand flies were captured from November 2016 to September 2018 using light traps of the Centers for Disease Control (CDC), in the neighborhood where VL cases were reported. Leishmania spp. circulation was evaluated by gut dissection and molecular analysis of the females captured. RESULTS Nyssomyia intermedia was the more frequent species (90,7%) within the 1,203 sand flies captured. We found no flagellates in dissected females, but two pools containing females of Ny. intermedia presented DNA of L. infantum. CONCLUSION Our results suggest that Ny. intermedia might be involved in the establishment of this new VL focus in Sao Paulo. However, before incriminating this species as a L. infantum vector, further studies should investigate other vectorial capacity parameters, including competence, survival, and feeding habits.

Gastrointestinal parasites in captive and free-living wild birds in Goiania Zoo / Parasitas gastrointestinais em aves silvestres em cativeiro e de vida livre no Zoológico de Goiânia

Helminths are endoparasites that infect a variety of bird species. Endoparasite infections can cause severe diseases, including kill captive avian hosts and represents a problem to maintenance and conservation. The eggs and larval forms of these parasites are usually eliminated in the host feces. The main interest of this study is to report the occurrence of eggs and oocysts in feces from captive wild birds in Goiânia Zoo and free-living birds in its surroundings. The fecal samples were subjected to parasitological examination to identify the presence of helminths and to classify their eggs based on morphological characteristics. Eggs of nematode parasites (Positive/N) were identified as Ascaridia spp. in Brotogeris chiriri (2/2), Dromaius novaehollandiae (1/1) and Rhea americana (2/2); Ascarididae in Pavo cristatus nigripensis (1/1); Capillaria spp. in Ara chloropterus (1/1) and Penelope jacucaca (1/1); Capillaria plagiaticia in Anodorhynchus hyacinthinus (1/2) and Ara spp. (2/2); Capillaria venusta in Rhamphastus tucanus (1/2); and unidentified nematode eggs from Amazona amazonica (2/2). Eimeria spp. oocyst was founded in feces from A. hyacinthinus (1/2). Considering free-living birds, Diphyllobothrium spp. eggs were founded in Ardea alba (2/2) and Nycticorax nycticorax (2/3). Co-infection of Eustrongylides spp. was founded in A. alba (1/2). This is the first occurrence of: Ascaridia spp. parasitizing B. chiriri; and C. venusta parasitizing R. tucanus. In conclusion, the helminth eggs found in the abovementioned host bird species are consistent with those reported in the literature, and treatment and control protocols were based on their identification.

Application of the small private online course-based blended teaching model in Human Parasitology teaching / 中国血吸虫病防治杂志

Small private online course (SPOC), an emerging network-based, student-centered blended teaching model, combines the advantages of online teaching and flipped classroom, aiming to effectively improve students’ autonomous learning ability and learning efficiency. Considering a remarkable decline in the course of Human Parasitology, we built an SPOC-based blended teaching model for Human Parasitology, covering pre-course learning, intra-course leaning, post-course consolidation and evaluation, and such a model was applied among grade 2019 students with specialty of clinical medicine. Following the application of the SPOC-based blended teaching model, most students had improvements in autonomous learning ability and activity, and understanding of human parasitology knowledge, and the examination score disparity was avoided.

Gastrointestinal parasites in captive and free-living wild birds in Goiania Zoo

Abstract Helminths are endoparasites that infect a variety of bird species. Endoparasite infections can cause severe diseases, including kill captive avian hosts and represents a problem to maintenance and conservation. The eggs and larval forms of these parasites are usually eliminated in the host feces. The main interest of this study is to report the occurrence of eggs and oocysts in feces from captive wild birds in Goiânia Zoo and free-living birds in its surroundings. The fecal samples were subjected to parasitological examination to identify the presence of helminths and to classify their eggs based on morphological characteristics. Eggs of nematode parasites (Positive/N) were identified as Ascaridia spp. in Brotogeris chiriri (2/2), Dromaius novaehollandiae (1/1) and Rhea americana (2/2); Ascarididae in Pavo cristatus nigripensis (1/1); Capillaria spp. in Ara chloropterus (1/1) and Penelope jacucaca (1/1); Capillaria plagiaticia in Anodorhynchus hyacinthinus (1/2) and Ara spp. (2/2); Capillaria venusta in Rhamphastus tucanus (1/2); and unidentified nematode eggs from Amazona amazonica (2/2). Eimeria spp. oocyst was founded in feces from A. hyacinthinus (1/2). Considering free-living birds, Diphyllobothrium spp. eggs were founded in Ardea alba (2/2) and Nycticorax nycticorax (2/3). Co-infection of Eustrongylides spp. was founded in A. alba (1/2). This is the first occurrence of: Ascaridia spp. parasitizing B. chiriri; and C. venusta parasitizing R. tucanus. In conclusion, the helminth eggs found in the abovementioned host bird species are consistent with those reported in the literature, and treatment and control protocols were based on their identification.
