O estudo zoológico realizado no Ensino Fundamental se apresenta como motivo de alto interesse por parte dos alunos. Dentre os grupos, os ofídios despertam grande fascínio em questões particulares, principalmente no questionamento sobre a classificação de serpentes peçonhentas. Com a preocupação de apontar os fatores prejudiciais no processo de aprendizado da temática, usou-se um questionário investigativo de identificação de características fisiomorfológicas com o objetivo de avaliar as literaturas didáticas sob a ótica do ensino das principais características das serpentes peçonhentas brasileiras, traçando um paralelo da influência direta que tais livros exercem sobre o conhecimento adquirido nos discentes analisados. Os dados apontam para uma maior eficiência da utilização de uma linguagem narrativa em relação aos quadros comparativos. Concluiu-se pela necessidade fundamental da implantação de revisões mais criteriosas, realizadas por especialistas, a fim de minimizar os impactos negativos e muitas vezes desastrosos no processo de aprendizagem dos nossos alunos.The zoological study conducted in Elementary Schools is presented as a reason for high interest from students. Among the groups, snakes evoke great fascination on particular issues, especially in questions about the classification of venomous snakes. Anxious to point out the harmful factors in the process of learning the subject, a questionnaire was used to identify investigative physio-morphological characteristics in order to assess the educational literature from the perspective of the teaching of the main characteristics of Brazilian venomous snakes, tracing parallels the direct influence of these books have on the knowledge gained from the students analyzed. The data suggest that more efficient use of a narrative language in relation to the comparative tables. It was concluded by the fundamental need of implementing more careful review, conducted by experts in order to minimize the negative and often disastrous in the learning process of our students.

- Abstract
Introduction: In Ecuador, poisonous snakebites are a public health problem. However, there is no recent hospital information from the Amazon. Objective: To retrospectively analyse the clinical-epidemiological characteristics of snakebites in patients admitted to a hospital in the Ecuadorian Amazon. Materials and methods: This is a cross-sectional study conducted at the Nueva Loja-Sucumbíos Provincial Hospital, bordering Colombia (2017-2021). Demographic, epidemiological and clinical variables, and condition at hospital discharge, were obtained from the epidemiological file of the Ministerio de Salud Pública. Results: In 5 years, 147 patients (29.4 per year) were hospitalized with no mortality. They corresponded to 26, 34, 32, 29 and 26 cases, in 2017, 2018, 2019, 2020 and 2021, respectively. Men with 99 (67.3%), aged 21-30 years with 28, mixed race with 94 cases, students, and farmers, were the most affected. The most affected (99; 67.3%) were men, people 21 to 30 years-old (28; 19.0%), mestizos (94; 63.9%), students, and farmers. The median age was 28 (range: 4-81) years. Prevalence was higher in April, June, and September. All accidents were caused by Viperidae snakes. Twenty (13.6%) cases were mild, (61.2%) were moderate and 37 (25.2%) were severe. The feet with 45 were the most bitten. Pre-hospitalization anti-venom serum was received by 53.1% and tourniquet by 19.8% patients. Median hospital arrival time was 5 (range 1-192) hours, mostly between 2-3 hours with 41 cases. No statistically significant differences were found considering the severity. Conclusions: A high prevalence of snakebites was evidenced in the north of the Amazon in Ecuador, with a higher incidence in the rainy season and all by Viperidae species. It is important to highlight the null mortality. Information campaigns on prevention and first aid, such as discouraging the use of tourniquets, especially among vulnerable groups.

Resumen El objetivo de este estudio fue evaluar las características clínicas del loxoscelismo dermonecrótico (LDN) en equinos del departamento de Córdoba, Colombia. El estudio, fue de tipo descriptivo, no probabilístico, las muestra fueron seleccionadas por conveniencia. Se utilizaron nueve caballos criollos (Equus ferus caballus) y dos burros (Equus asinus africanus) con LDN diagnosticados clínica e histopatológicamente en diferentes producciones del Departamento. Al describir las lesiones cutáneas, éstas se caracterizaron por la presencia de una severa dermatitis necrótica, con edema y un área eritematosa focal, al detallar el área lesionada, se observó un punto necrótico central y dos halos alrededor (un halo blanco medial y un halo violáceo más externo) en la mayoría de los casos estudiados; así como ausencia de signos neurológicos y sistémicos. Las lesiones se ubicaron en la mayoría de los casos a nivel dorsal, seguido de la región rostral, pecho y pene. Histopatológicamente en la coloración de Hematoxilina Eosina (H&E), se observó severa dermatitis piogranulomatosa, con marcada infiltración de polimorfonucleares especialmente neutrófilos, con vacuolización de la capa basal de la epidermis y edema en la unión dermo-epidérmica. El diagnóstico definitivo de LDN en los 11 animales estudiados, se fundamentó en las manifestaciones clínicas observadas, las características anatomopatológicas de las lesiones y los resultados histopatológicos. El presente informe constituye el primer reporte de LDN en el Departamento de Córdoba, ya que no se encontraron reportes en la literatura consultada. Abstract The aim of this study was to characterize the clinical aspects of dermonecrotic loxoscelism (LDN) in horses department of Cordoba, Colombia. This study was descriptive, not probabilistic, in animals of convenience. Nine horses (Equus ferus caballus) and 2 donkeys (Equus asinus africanus) were used with LDN diagnosed clinically and histopathologically in different productions of the Department. When describing the skin lesions, these were characterized by the presence of severe necrotic dermatitis, with edema and a focal erythematous area, when detailing the injured area, a central necrotic spot and two halos around it (a medial white halo and a halo Violet) in most of the cases studied; As well as absence of neurological and systemic signs. The lesions were located in most cases at the dorsal level, followed by the rostral region, chest and penis. Histopathologically in the staining of Hematoxylin Eosin (H & E), severe piogranulomatous dermatitis was observed, with marked infiltration of polymorphonuclear cells especially neutrophils, with vacuolization of the basal layer of the epidermis and edema in the dermo-epidermal junction. The definitive diagnosis of LDN in the 11 animals studied was based on the clinical manifestations observed, the anatomopathological characteristics of the lesions and the histopathological results. The present report constitutes the first LDN report in the Department of Córdoba, since no reports were found in the consulted literature.

El conocimiento parcial de estadísticas nacionales acerca de accidentalidad por animales venenosos con distribución geográfica en Colombia, motiva el estudio de dichas circunstancias. El objetivo fue realizar una línea base acerca de los accidentes con animales venenosos reportados a la línea telefónica de asesoría toxicológica, los cuales provienen de todo el país, tomando como punto de partida las bases de datos que se han obtenido en el transcurso de cinco años de funcionamiento de la misma. Se encontraron, reportados y atendidos, 1783 casos de los cuales el 47% correspondió a accidente ofídico (evento de notificación obligatoria para Colombia), 25% por escorpiones y 11% por arañas, seguidos de otros que tienen representación epidemiológica menor aunque valiosa, en los principales departamentos de incidencia que fueron Antioquia, Valle del Cauca y Cundinamarca. La base de datos analizada presenta una perspectiva general de la problemática que sirva como base de investigaciones para favorecer programas de salud pública al respecto e incrementar la capacidad de respuesta de las comunidades, instituciones y profesionales del sector salud. / Abstract.
