RESUMO
The impact of Covid-19 on envenomations by venomous animals in countries heavily affected by both conditions has not been quantified yet. Brazil shows high incidence of envenomations by scorpions, spiders and snakes and was heavily affected by waves of Covid-19. To determine how the pandemic impacted the epidemiology of envenomations by those three groups of venomous animals, we used online databases from two surveillance sources on number of cases and mortality. During the years before and during the pandemic, scorpion stings typically occurred in adults of both sexes in urban zones in the Southeast and Northeast regions. Spider bites occurred mainly in the South region, in adults of both sexes in urban zone. Snakebites affected mainly rural adult men in the Amazon. Between 2007 and 2021, overall incidence of cases by scorpions, spiders and snakes decreased after the beginning of the pandemic, snakebites did not show changes after the pandemic started in Brazil, but cases by scorpions and spiders decreased. No changes in the incidence of deaths were observed. On national level, Covid-19 affected some demographic, clinical and epidemiological aspects in cases by scorpions, spiders and snakes.

Losses and the economic impact of dog attacks (DAs) on livestock are often overlooked and include factors such as decreased production, expenses for treatment and handling, and death of injured animals. This study evaluated the epidemiological, therapeutic, and pathological findings of DAs on livestock over an 11-year survey using the records of farm animals referred to a Veterinary Teaching Hospital. Livestock attacked by dogs included 31 sheep, 11 horses, 3 cattle, 3 goats, and 2 pigs, totaling 50 animals. Anatomical locations injured by dog bites were identified as head/neck, thoracic/pelvic limbs, abdomen/flank, rump/tail, and multiple affected regions (two or more bite sites). Additionally, the severity of the injuries was classified into four degrees adapted from the classification of dog bite injuries in children. Most livestock presented Grade 1 (26%) and Grade 2 (28%) injuries, while Grade 3 and Grade 4 injuries were observed in 46% of DAs. Furthermore, 35 animals (70%) were discharged, 9 (18%) died, and 6 (12%) were humanely euthanized. DAs may represent a significant cause for referring livestock species to clinical care, severe injuries, and a considerable number of deaths. In this study, we provide information regarding DAs on livestock for the first time in Midwestern Brazil.
RESUMO
PURPOSE: Incisional ventral hernias (IVH) are common after laparotomies, with up to 20% incidence in 12 months, increasing up to 60% at 3-5 years. Although Small Bites (SB) is the standard technique for fascial closure in laparotomies, its adoption in the United States is limited, and Large Bites (LB) is still commonly performed. We aim to assess the effectiveness of SB regarding IVH. METHODS: We searched for RCTs and observational studies on Cochrane, EMBASE, and PubMed from inception to May 2023. We selected patients ≥ 18 years old, undergoing midline laparotomies, comparing SB and LB for IVH, surgical site infections (SSI), fascial dehiscence, hospital stay, and closure duration. We used RevMan 5.4. and RStudio for statistics. Heterogeneity was assessed with I2 statistics, and random effect was used if I2 > 25%. RESULTS: 1687 studies were screened, 45 reviewed, and 6 studies selected, including 3 RCTs and 3351 patients (49% received SB and 51% LB). SB showed fewer IVH (RR 0.54; 95% CI 0.39-0.74; P < 0.001) and SSI (RR 0.68; 95% CI 0.53-0.86; P = 0.002), shorter hospital stay (MD -1.36 days; 95% CI -2.35, -0.38; P = 0.007), and longer closure duration (MD 4.78 min; 95% CI 3.21-6.35; P < 0.001). No differences were seen regarding fascial dehiscence. CONCLUSION: SB technique has lower incidence of IVH at 1-year follow-up, less SSI, shorter hospital stay, and longer fascial closure duration when compared to the LB. SB should be the technique of choice during midline laparotomies.

Este relato de caso aborda o curso clínico de um envenenamento botrópico ocorrido no município de Jarinu, SP, no ano de 2021. O paciente necessitou de fasciotomia em membro superior após síndrome compartimental aguda com enxertia dermoepidérmica em um segundo momento cirúrgico. No pós-operatório tardio, o paciente evoluiu com retração, necessitando de reabordagem cirúrgica com correção de retração de membro superior esquerdo. Discute-se a gravidade do acidente ofídico, efeitos do veneno nos tecidos, complicações, síndrome compartimental aguda, indicação e técnica da fasciotomia descompressiva com base na literatura.
This case study examines the clinical course of a Bothrops snakebite poisoning that occurred in Jarinu, São Paulo, Brazil, in 2021. The patient required a fasciotomy in the upper limb due to acute compartment syndrome, followed by a second surgical procedure involving dermo-epidermal grafting. In the late postoperative period, the patient experienced retraction, leading to a subsequent surgical intervention to correct the retraction in the left upper limb. The severity of the snakebite accident, the effects of venom on tissues, complications, acute compartment syndrome, as well as the indications and techniques for decompressive fasciotomy, are discussed based on the available literature.
RESUMO
Resumen Las infecciones por mordeduras de perros y gatos presentan una etiología bacteriana mixta con microorganismos aerobios y anaerobios que provienen de la cavidad oral del agresor y, en menor medida, de la piel del agredido y el medio ambiente. Con mayor frecuencia se aíslan Pasteurella multocida, Pasteurella canis, Streptococcus spp., Staphylococcus spp., Corynebacterium spp., Capnocytophaga canimorsus y anaerobios. Si bien las infecciones por mordeduras de animales no son infrecuentes, algunos de los microorganismos implicados son excepcionales. Neisseria weaveri forma parte de la microbiota orofaríngea de perros y gatos; sin embargo, los casos comunicados debidos a mordeduras son escasos.
Abstract Infections caused by dog and cat bites have a mixed bacterial etiology with aerobic and anaerobic microorganisms that come from the mouth of the offender and, to a lesser extent, from the skin of the victim and the environment. Pasteurella multocida, Pasteurella canis, Streptococcus spp., Staphylococcus spp., Corynebacterium spp., Capnocytophaga canimorsus and anaerobes can be frequently isolated. Although animal bite infections are not uncommon, some of the microorganisms involved are rare. Neisseria weaveri is part of the oropharyngeal microbiota of dogs and cats; however, reported cases due to bites are rare.

RESUMO
Cases of araneism reported in the province of Chubut (Argentina) have tripled in the last two decades, and almost 80 % of them involve Latrodectus mirabilis (Holmberg) (Araneae: Theridiidae). According to descriptions of the life cycle of this species in Argentina, the low temperatures typical of autumn-winter cause the death of all adult spiders, so that no adult specimens of L. mirabilis are observed in winter. Field samplings, observations by the Grupo de Entomología Patagónica (GENTPAT, IPEEC CCT CENPAT CONICET), and citizen reports for more than 15 years suggested a similar cycle in northeastern Patagonia. However, for the last three consecutive years, we have recorded adult females in the field throughout the Patagonian winter. Some of these individuals even survived the winter and were alive the following spring. The purpose of this note is to report the field presence of adult female specimens of L. mirabilis in the outskirts of the city of Puerto Madryn (Chubut, Argentina) during the last three consecutive winters corresponding to the years 2021, 2022 and 2023; and to note that at least two of them survived the winter, arriving alive (and in good condition) the following spring. Given the medical importance of this spider, the publication of this information, the context of the findings, and their ecological implications will help to prevent its spread and reduce the likelihood of accidents.

Bat-mediated human rabies is a viral zoonotic disease that poses a serious threat to the public health of traditional peoples, especially indigenous populations that maintain primitive cultural and social habits, such as the Maxakali ethnic group, located in the southeastern region of Brazil. The sociocultural habit of this population led to the emergence between April and May 2022 of the viral spillover of rabies transmitted by bats, which decimated the lives of four children from this population who maintained contact with this animal as a recreational practice. Because the vampire bats Desmodus rotundus have exceptional ecology and social characteristics that can have important effects on the dynamics of viral dispersion in this indigenous population, I present the dynamics of contact between native children and the bat and the meaning of this relationship, which involves ritualistic and recreational significance. As important as knowing the reasons for this practice is discussing some intrinsic and extrinsic factors that imply risks that intensify the vulnerability of this population to the transmission of the rabies virus at any time. In view of this, I warn of the need to adopt efficient strategies to mitigate the risks of a new emergency in this region. Although emergency containment measures were carried out during the critical period of the outbreak, such animal and environmental control actions must become routine programmatic and structuring interventions. Essential for rabies surveillance in this population is to develop culturally adapted interethnic health education campaigns to guarantee the accessibility of the Maxakali indigenous people to the content taught, so that any attempt at domestication, captivity and recreational practices with bats of any species is discouraged, thus avoiding a possible re-emergence of this anthropozoonosis that has impacted not only the epidemiological scenario in this region, but throughout Brazil, and also throughout Latin America.

ABSTRACT BACKGROUND: Loxosceles spp are arthropods found worldwide. Its bite may produce cutaneous loxoscelism (necrotic or edematous) or cutaneous-visceral loxoscelism. Depending on their severity and location, cutaneous forms are managed with local cold application and systemic administration of antihistamines, corticosteroids, antibiotics, polymorphonuclear inhibitors, and analgesics. OBJECTIVE: This study aimed to report a case of cutaneous loxoscelism and to identify the main dermatological manifestations associated with the Loxosceles spp bite. DESIGN AND SETTING: This case report and literature review was conducted in a Mexican university. METHODS: A detailed report on the medical management of a patient with cutaneous loxoscelism treated at the emergency department of a public hospital was published. Scopus, PubMed, Web of Science, and Google Scholar databases were searched to identify articles reporting cutaneous loxoscelism. The following keywords were used during the database search: "loxoscelism" OR "spider bite," OR "loxosceles" OR "loxosceles species" OR "loxosceles venom" OR "loxoscelism case report" AND "cutaneous" OR "dermonecrotic arachnidism." RESULTS: A 62-year-old female patient with cutaneous loxoscelism was treated with systemic dapsone and local heparin spray. Eighteen studies with 22 clinical cases were included in this systematic review. Of the 22 patients, 12 (54.5%) were men. L. rufescens was the predominant spider species. CONCLUSIONS: The administration of dapsone and heparin for the management of cutaneous loxoscelism demonstrated success in this case, with no sequelae observed. In general, the literature review indicated favorable outcomes in patients treated with antimicrobials and corticosteroids, with continuous healing of skin lesions.

RESUMO
RESUMO O propósito deste estudo foi reportar as alterações oculares observadas após picada de abelha com ferrão retido na córnea. Destacamos o tratamento e o desfecho de uma lesão de córnea incomum e sua patogênese. Trata-se de relato de caso e revisão da literatura de lesões oculares por picada de abelha. Paciente do sexo feminino, 63 anos, procurou atendimento oftalmológico de urgência devido à picada de abelha na córnea do olho direito há 6 dias. Queixava-se de embaçamento visual, dor e hiperemia ocular. Apresentou acuidade visual de vultos no olho afetado. Ao exame, notaram-se hiperemia moderada de conjuntiva bulbar, edema corneano com dobras de Descemet e presença do ferrão alojado na região temporal, no estroma profundo da córnea. A paciente foi internada para ser abordada no centro cirúrgico sob anestesia geral. Durante a cirurgia, o ferrão teve que ser retirado via câmara anterior, mediante a realização de uma paracentese e uma lavagem da câmara anterior, com dupla via e solução salina balanceada. Ainda não existe na literatura um tratamento padrão na abordagem de pacientes com lesões oculares por picada de abelha, sendo importantes a identificação e o reconhecimento precoce de possíveis complicações que ameacem a visão.
ABSTRACT The purpose of this study was to report the ocular changes observed after a bee sting with a stinger retained in the cornea. We show the treatment and outcome of an unusual corneal injury and its pathogenesis. This is a case report and literature review of ocular injuries caused by bee stings. A 63-year-old female patient sought emergency ophthalmic care because of a bee sting on the cornea of her right eye six days before. She complained of blurred vision, pain, and ocular hyperemia. She had glare sensitivity on visual acuity in the affected eye. Examination revealed moderate hyperemia of the bulbar conjunctiva, corneal edema with Descemet's folds and a stinger lodged in the temporal region, in the deep stroma of the cornea. The patient was admitted to the operating room under general anesthesia. During surgery, the stinger had to be removed via the anterior chamber, by performing a paracentesis and washing the anterior chamber with a double flushing and balanced saline solution. There is still no standard treatment in the literature for patients with eye injuries caused by bee stings, and early identification and recognition of possible sight-threatening complications is important.

Introduction: Millions of snake bites occur worldwide each year. Clinical practice guidelines generally do not recommend the use of prophylactic antibiotics. Objective: To determine the sociodemographic, clinical, and pharmacological variables and the use of antibiotics in a group of patients with snake bites in Colombia. Methods: A retrospective cross-sectional study was carried out. Patients affiliated with a Colombian health insurer who presented with snake bites between 2015 and 2022 were included. The cases were identified from the National Public Health Surveillance System. Sociodemographic, clinical and pharmacological variables were identified. Descriptive and bivariate analyses were performed. Results: A total of 643 patients were analyzed, with a median age of 30.8 years, and 74.7% were men. The most frequently identified genus of snake was Bothrops (88.8%), and most incidents were classified as mild ophidian accidents (61.6%). A total of 59.7% of patients received snake antivenom. A total of 13.8% and 2.2% of the patients had cellulitis or abscesses, respectively. A total of 63.5% received antibiotics (50.6% for prophylaxis and 12.9% for treatment), especially cephalexin (25.9%), and most of the antibiotic management was considered inappropriate (91.7%). Conclusion: Most patients with snake bites received antibiotics, especially for prophylactic purposes, a clinical behavior that goes against current evidence. The use of antibiotics with an unsuitable spectrum for the microorganisms that are usually found in the wounds of these patients is frequent. The development of local clinical practice guidelines is required to help reduce the overprescription of antibiotics, as the excessive use of antimicrobials is the main determinant of antimicrobial resistance.
RESUMO
The high complexity of the oral microbiota of healthy dogs and the close exposure of humans to companion animals represent a risk of the transmission of potential zoonotic microorganisms to humans, especially through dog bites, including multidrug-resistant ones. Nonetheless, a limited number of comprehensive studies have focused on the diversity of the microorganisms that inhabit the oral cavities of healthy dogs, particularly based on modern molecular techniques. We investigated bacterial and fungal organisms in the oral cavities of 100 healthy dogs based on a combination of conventional and selective microbiological culture, mass spectrometry (MALDI-TOF MS), and next-generation sequencing. In addition, in vitro antimicrobial susceptibility patterns of isolates and mecA resistance gene were assessed. A total of 213 bacteria and 20 fungi were isolated. Staphylococcus pseudintermedius (40/100 = 40%), α-hemolytic Streptococcus (37/100 = 37%), and Pasteurella stomatis (22/100 = 22%) were the most prevalent bacteria diagnosed by microbiological culture and MALDI-TOF MS, whereas Aspergillus (10/100 = 10%) was the most common fungi identified. Based on next-generation sequencing of selected 20 sampled dogs, Porphyromonas (32.5%), Moraxella (16.3%), Fusobacterium (12.8%), Conchiformibius (9.5%), Bergeyella (5%), Campylobacter (3.8%), and Capnocytophaga (3.4%) genera were prevalent. A high multidrug resistance rate was observed in Staphylococcus pseudintermedius isolates, particularly to azithromycin (19/19 = 100%), penicillin (15/19 = 78.9%), and sulfamethoxazole/trimethoprim (15/19 = 78.9%). In addition, the mecA resistance gene was detected in 6.1% (3/49) of coagulase-positive staphylococci. Here, we highlight the microbial complexity of the oral mucosa of healthy dogs, including potential zoonotic microorganisms and multidrug-resistant bacteria, contributing with the investigation of the microbiota and antimicrobial resistance patterns of the microorganisms that inhabit the oral cavity of healthy dogs.

Rabies is a viral zoonotic disease that can infect all mammals and the main route of transmission to human is attributed to dog bites. Due to the limited information available about the rabies vaccination coverage, although Ecuador is supposed to be free of rabies, we conducted a retrospective study of the epidemiological surveillance records on the notification of dog attacks to humans in Guayaquil, the most populated city in Ecuador. The results showed an annual incidence rate of 105.6 dog bites per 100,000 inhabitants, where the most affected anatomical parts are the lower extremities; individuals from 1 to 14 years of age were the most affected age group (IC95% 1.42-1.92; p < 0.001). As for the severity of the wounds, most of them (65%) were mild. Moreover, 25% of the dogs were free roaming ones, and only 43% of the dogs with owner had a complete vaccination scheme against rabies virus. We found a important dog attack rate in Guayaquil city and more than half of the dogs involved were not vaccinated against rabies. Under a potential scenario of rabies circulation in canine population, there would be a serious risk for rabies transmission to humans. Hence, it is important to reinforce rabies surveillance and vaccination programs aligned to the One Health concept to manage this public health issue.
RESUMO
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.
Introducción. En Ecuador, las mordeduras de serpientes venenosas son un problema de salud pública. Sin embargo, no existe información hospitalaria reciente desde la Amazonía. Objetivo. Analizar retrospectivamente las características clínico-epidemiológicas de las mordeduras de serpientes en pacientes ingresados en un hospital de la Amazonía del Ecuador. Materiales y métodos. Se llevó a cabo un estudio transversal en el hospital provincial de Nueva Loja (Sucumbíos), que colinda con Colombia, 2017-2021. La información sobre las variables demográficas, epidemiológicas y clínicas, y la condición al egreso hospitalario, se obtuvieron de la ficha epidemiológica del Ministerio de Salud Pública. Resultados. En cinco años se hospitalizaron 147 pacientes (29,4 por año), sin que se presentaran muertes. Corresponden a 26, 34, 32, 29 y 26 casos, en el 2017, 2018, 2019, 2020 y 2021, respectivamente. Según el sexo, los más afectados fueron los hombres (n=99; 67,3 %), según el grupo etario, los de 21 a 30 años (n=28; 19,0 %) y, según la raza, los de etnia mestiza (n=94; 63,9 %), estudiantes y agricultores. La mediana de edad fue de 28 años (rango: 4 a 81). Hubo mayor prevalencia en abril, junio y septiembre. Todos los accidentes fueron causados por serpientes Viperidae. Veinte (13,6 %) casos fueron leves, 90 (61,2 %), moderados, y 37 (25,2 %), graves. La mordedura fue más frecuente en los pies (45 casos). El 53,1 % recibió suero antiofídico antes de la hospitalización y en el 19,8 % de los pacientes se colocó un torniquete. La mediana de tiempo de llegada al hospital fue de 5 horas (rango: 1-192), y lo más frecuente fue entre 2 y 3 horas (41 casos). No se encontraron diferencias estadísticamente significativas según la gravedad del caso. Conclusiones. Se evidenció una gran prevalencia de mordeduras de serpientes en el norte de la región amazónica-Ecuador, con mayor incidencia en la estación lluviosa y todas causadas por Viperidae. Es importante resaltar la mortalidad nula. Las campañas informativas sobre prevención y primeros auxilios, como la desmotivación del uso de torniquetes, serían fundamentales para reducir los casos, especialmente, en los grupos vulnerables.

Despite being an important public health issue, particularly due to rabies, dog bites and associated risk factors have rarely been assessed by health services from a One Health perspective. Accordingly, the present study aimed to assess dog biting and associated demographic and socioeconomic risk factors in Curitiba, the eighth-largest Brazilian city with approximately 1.87 million people, based on the post-exposure prophylaxis (PEP) rabies reports between January/2010 and December/2015. The total of 45,392 PEP reports corresponded to an average annual incidence of 4.17/1000 habitants, mainly affecting white (79.9%, 4.38/1000 population), males (53.1%, 4.81/1000 population), and children aged 0-9 years (20.1%, 6.9/1000 population), with severe accidents associated with older victims (p < 0.001) and mainly caused by dogs known to the victims. An increase of USD 100.00 in the median neighborhood income was associated with a 4.9% (95% CI: 3.8-6.1; p < 0.001) reduction in dog bites. In summary, dog biting occurrence was associated with victims' low income, gender, race/color, and age; severe accidents were associated with elderly victims. As dog bites have been described as multifactorial events involving human, animal, and environmental factors, the characteristics presented herein should be used as a basis to define mitigation, control, and prevention strategies from a One Health perspective.
RESUMO
Introducción. En Ecuador, las mordeduras de serpientes venenosas son un problema de salud pública. Sin embargo, no existe información hospitalaria reciente desde la Amazonía. Objetivo. Analizar retrospectivamente las características clínico-epidemiológicas de las mordeduras de serpientes en pacientes ingresados en un hospital de la Amazonía del Ecuador. Materiales y métodos. Se llevó a cabo un estudio transversal en el hospital provincial de Nueva Loja (Sucumbíos), que colinda con Colombia, 2017-2021. La información sobre las variables demográficas, epidemiológicas y clínicas, y la condición al egreso hospitalario, se obtuvieron de la ficha epidemiológica del Ministerio de Salud Pública. Resultados. En cinco años se hospitalizaron 147 pacientes (29,4 por año), sin que se presentaran muertes. Corresponden a 26, 34, 32, 29 y 26 casos, en el 2017, 2018, 2019, 2020 y 2021, respectivamente. Según el sexo, los más afectados fueron los hombres (n=99; 67,3 %), según el grupo etario, los de 21 a 30 años (n=28; 19,0 %) y, según la raza, los de etnia mestiza (n=94; 63,9 %), estudiantes y agricultores. La mediana de edad fue de 28 años (rango: 4 a 81). Hubo mayor prevalencia en abril, junio y septiembre. Todos los accidentes fueron causados por serpientes Viperidae. Veinte (13,6 %) casos fueron leves, 90 (61,2 %), moderados, y 37 (25,2 %), graves. La mordedura fue más frecuente en los pies (45 casos). El 53,1 % recibió suero antiofídico antes de la hospitalización y en el 19,8 % de los pacientes se colocó un torniquete. La mediana de tiempo de llegada al hospital fue de 5 horas (rango: 1-192), y lo más frecuente fue entre 2 y 3 horas (41 casos). No se encontraron diferencias estadísticamente significativas según la gravedad del caso. Conclusiones. Se evidenció una gran prevalencia de mordeduras de serpientes en el norte de la región amazónica-Ecuador, con mayor incidencia en la estación lluviosa y todas causadas por Viperidae. Es importante resaltar la mortalidad nula. Las campañas informativas sobre prevención y primeros auxilios, como la desmotivación del uso de torniquetes, serían fundamentales para reducir los casos, especialmente, en los grupos vulnerables.
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.

Dog and cat aggressions are public health concerns associated with rabies transmission to the human population. The social and environmental conditions of marginalized and urban areas stand a risk due to people's contact with dogs. This study aimed to identify spatial patterns related to dog and cat aggression in a densely populated area in the center of Mexico City, analyzing the risk of aggression at the census unit level in the 2018-2020 triennium. This cross-sectional study was carried out in Coyoacán, in the south-central area of Mexico City's urbanized region. The total number of cases (n = 1,078) was obtained from monthly records of aggressions by dogs and cats, from the Control and Prevention of Zoonoses-Rabies Program of the Coyoacán Sanitary Jurisdiction. The information collected was related to the victims and the aggressors. Associations between the occurrence of bites and the characteristics of the victim were evaluated using a geographic information system (GIS), as well as the spatio-temporal distribution of the aggressions to the census unit level. Out of 1,078 cases reported, 977 (90.6%) were caused by dogs and 101 (9.4%) by cats, 55.1% (n = 587) occurred within the same household, and 13.7% (n = 148) were categorized as severe injuries. Adult men were the most affected group. Attacks on the street had a higher risk of resulting in a severe injury, compared to those that occurred at home (OR 1.63, 95CI 1.15 - 2.31, p <0.006). According to the standardized rate of the triennium, the values ââranged between 54.1 and 619 aggressions per 100,000 inhabitants, and summer was the season with a higher probability of occurrence. These results provide a basis for the analytical investigation of the spatial patterns of dog and cat aggression, highlighting the need to implement efficient surveillance systems and public health strategies.

Introducción : Es de vital importancia considerar que la toxina del veneno de la avispa puede ocasionar una reacción violenta que daña la función visual, es por ello que presentamos el siguiente caso relacionado. Cuadro Clínico : Mujer de 32 años con antecedente de picadura de avispa hace 24 horas en ojo derecho; disminución de la agudeza visual, enrojecimiento, lagrimeo, dolor, secreción; agudeza visual de cuenta dedos a 2 metros del ojo derecho y 20/25 ojo izquierdo, con presiones intraoculares de 12 y 13; biomicroscopía hiperemia conjuntival con inyección periciliar 3+, cuerpo extraño en córnea hasta estoma con edema 3+, estrías en la Descemet ojo derecho. Resultados : Se procede a la extracción del cuerpo extraño con previa protección antimicrobiana con antibiótico tobramicina, antiinflamatorio esteroideo prednisolona, hipertónicas y lubricante mixto carboximetilcelulosa y glicerina. A la semana, se observa la formación de una opacidad capsular anterior con signos de atrofia iridiana que empieza a dar un "cambio de color del iris", a las dos semanas se evidencia la dilatación de la vasculatura periciliar, a horas 4, y a las 3 semanas el paciente presenta una agudeza visual de 20/25 ambos ojos, con transparencia corneal, persistencia de la atrofia iridiana y catarata traumática capsular anterior, con remisión de sintomatología en el paciente. Conclusiones : No se sabe el componente exacto del veneno que produce los signos previamente descritos, existen teorías de que puede deberse a un componente con acción parasimpaticomimética, el mismo que se relaciona a otras observaciones clínicas de despigmentación local y heterocromía.
Introduction : It is very important to consider that the toxin present in wasp venom may lead to a severe reaction damaging visual function. This is the reason why we present the following case. Clinical Picture : This is a 32-year-old-female who was bitten by a wasp 24 hours ago in her right eye. She had visual acuity reduction, reddening, tearing, pain, and secretion. Her visual acuity was counting fingers at two-meter distance from her right eye and 20/25 in the left eye. Intraocular pressure was 12 and 13. Biomicroscopy showed conjunctival hiperemia with 3+ periciliary injection. There was a foreign body in the cornea towards the stoma, with 3+ edema. There were striae in the right Descemet. Resultados: We took out the foreign body with previous antimicrobial protection including an antibacterial (tobramycin) and a steroid anti-inflammatory compound (prednisolone). Hypertonic solution and mixed lubricants were also administered, including a mixed lubricant, carboxymethylcellulose, and glycerin. One week afterwards, we observed the formation of an anterior capsular opacity with signs of iris atrophy which led to a 'change of color in the iris'. Two weeks afterwards we observed periciliary vascular dilatation, at 4-hour meridian; and on the third week, the patient had 20/25 visual acuity in both eyes. Her cornea was transparent, there was persistence of iris atrophy, and there was an anterior capsular cataract. Her symptoms subsided. Conclusiones : The exact component of wasp venom leading to the described signs is not known. It has been proposed that it may be a compound with parasympathomimetic action, and this has been related with other clinical observations indicating local depigmentation and heterochromia.
RESUMO
Venomous fish are commonly found in Brazilian waters. The most important marine venomous fish species are stingrays (Dasyatidae, Gimnuridae, Myliobatidae, and Rhinopteridae families), catfish (Ariidae family), scorpionfish and lionfish (both Scorpaenidae family), and toadfish (Batrachoididae family). Meanwhile, Potamotrygonidae stingrays and Pimelodidae catfish are the most important venomous freshwater fish. The mechanisms of envenomation vary and involve various venomous apparatuses and glands. Despite not being highly developed, these venomous apparatuses in fish appear rudimentary, using structures such as fins and rays to inoculate toxins and rarely presenting with specialized structures. Toxins are produced by glandular tissue made up of proteinaceous cells, lacking true glands, and are positioned along the inoculation structures. However, systemic manifestations are rare. No antivenom serum has been developed for any species of American venomous fish. Brazilian venomous fish and their venoms have only recently attracted attention, leading to new studies not only addressing clinical issues in humans, but also exploring the discovery of new active substances with immense pharmacological potential.
