Alterações oculares decorrentes de picada de abelha na córnea / Ocular changes due to corneal bee sting

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.

Utilization of dapsone and hemoglobin in the epithelial skin regeneration therapy of cutaneous loxoscelism: A case report and integrative literature review

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.

A Study of Clinico-social Profile of Animal Bite Patients Attending the Antirabies Clinic of BRD Medical College, Gorakhpur

Background: Rabies is one of zoonotic viral disease, estimated to cause 59000 human deaths annually in over 150 countries, of which 20,000 are from India alone; about 40% of which are in children under the age of 15. Rabies though 100% fatal is preventable with post-exposure prophylaxis which includes wound washing, anti-rabies vaccination and rabies immunoglobulin. Objective: To describe the clinico-social profile of animal bite patients attending the anti-rabies clinic of BRD Medical College, Gorakhpur. Methodology: A cross-sectional study was conducted in the anti-rabies clinic of Nehru hospital, BRD Medical College, Gorakhpur from January 2022 to May 2022. Study participants were interviewed by using a pre-phrased, pre-designed and pre-tested questionnaire. Data regarding socio-demographic and clinical profile of the study participants following animal bite exposure was collected. Results: The total number of animal bite victims were 250, in which majority of them were males (76.77%) and highest percentage was of adult population (20-59 years). Maximum number of victims were from rural area (78.70%). 19.35% were working and 39.35% were students. 77.43% were category III bites and in 50.96% cases lower limb was the site of bite and dogs were responsible for 89.67% of the bites. 60.64% victims did not wash the wound properly before reaching the anti-rabies clinic. Conclusion: This study concludes that as majority of the animal bite victims were students and majority of victims were unaware about the importance of wound care, therefore a step can be taken to create awareness in various schools.

Epidemiología y características clínicas de las mordeduras de serpientes venenosas en el norte de la Amazonía del Ecuador (2017-2021) / Epidemiology and clinical features of venomous snake bites in the Northern Amazon of Ecuador (2017-2021)

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.

Picadura de insecto en la córnea, a propósito de un caso

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.

Envenomations caused by fish in Brazil: an evolutionary, morphological, and clinical vision of a neglected problem

ABSTRACT 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.

Profile of human anti-rabies care and post-exposure prophylaxis in the state of São Paulo

ABSTRACT Background: Rabies is an anthropozoonosis that greatly impacts public health and is transmitted by infected mammals. Aggression by animals is notifiable and may result in anti-rabies post-exposure prophylaxis (PEP). This study aimed to characterize anti-rabies PEP notifications in São Paulo state, Brazil. Methods: A descriptive study was conducted using data provided by the SINAN between 2013 and 2017. Results: A total of 572,889 aggressions were recorded during the study period, characterized mostly by dogs (83.5%), single wounds (56.9%), superficial wounds (58.6%), and hands/feet (34.6%). Conclusions: Animal observation was the most frequent recommendation, even in cases of attacks from non-domestic animals.

Objective: to describe the completeness of notifications of accidents involving venomous animals held on the Notifiable Health Conditions Information System (SINAN), in Brazil and its macro-regions, from 2007 to 2019. Methods: we analyzed essential and non-mandatory fields for snakebite, spider bite and scorpion sting notifications, considering the following completeness categories: Excellent (≤ 5.0% incompleteness), Good (5.0% to 10.0%), Regular (10.0% to 20.0%), Poor (20.0% ≤ 50.0%) and Very Poor (> 50.0%). Proportional change in completeness between 2007 and 2019 was estimated. Results: 1,871,462 notifications were investigated. The "localized manifestations", "systemic manifestations", "case classification", "case progression" and "zone of occurrence" fields had excellent or good completeness. Completeness was regular or poor for the "schooling" and "race/color" fields. The "occupation" field was predominantly poorly or very poorly filled in. There was a proportional worsening in completeness ((VP < 0) in most regions for the "zone of occurrence", "case progression" and "schooling" fields. Conclusion: completeness of most fields improved, although socioeconomic and occupational fields require more attention.

Mordeduras de ofidios en mano pediátrica y sus complicaciones locales / Snake bites in pediatric hand and their local complications / Mordidas de serpentes de mão pediátricas e suas complicações locais

Introducción: el envenenamiento por mordedura de ofidios es reconocido como un problema de salud pública según la Organización Mundial de la Salud. La baja incidencia sumada a la diversidad de presentaciones clínicas, edades, topografías afectadas, así como los diferentes protocolos en la bibliografía existente sobre algunos aspectos del tratamiento, hacen difícil el manejo sistematizado de estos pacientes. El objetivo de este trabajo es realizar una revisión sistemática de la literatura sobre mordedura de serpientes en pacientes pediátricos con afectación en mano y miembro superior, haciendo hincapié en la conducta frente las complicaciones loco-regionales. Por importancia y frecuencia destacamos al síndrome compartimental, las flictenas y las infecciones. Metodología: se realizó una búsqueda bibliográfica en MedLine/PubMed con las palabras clave: "Snake Bite hand Children" y "Snake Bite compartimental syndrome". Se incluyeron los artículos publicados en los últimos 10 años (2012 al 2022). Resultados: la búsqueda de artículos ante las palabras "Snake Bite hand Children" resultó en 20 articulos y la busqueda ante las palabras "Snake Bite compartimental syndrome" derivó en 34. Luego de aplicar los criterios de inclusión y exclusión se obtuvieron 30 artículos para el análisis. Conclusiones: la población pediátrica se encuentra más expuesta a las mordeduras por serpientes y a su vez a presentar lesiones más severas. El tratamiento del síndrome compartimental continúa siendo un tema de debate. El veneno inoculado puede simular un síndrome compartimental que puede revertir sin fasciotomías con el tratamiento adecuado. Igualmente, ante síntomas y signos claros de síndrome compartimental se sugiere realizar fasciotomías frente a las graves secuelas potenciales. Ante la aparición de flictenas, el destechado cuidadoso de la misma es un tratamiento adecuado. La mayoría de los autores coinciden con el tratamiento profiláctico con antibioticoterapia.

Introduction: Ophidian bite poisoning is recognized as a public health problem by the World Health Organization. The low incidence added to the diversity of clinical presentations, ages, affected topographies, as well as the different protocols in the existing literature on some aspects of treatment, make the systematized management of these patients difficult. The aim of this work is to carry out a systematic review of the literature on snakebite in pediatric patients with hand and upper limb involvement, with emphasis on the management of loco-regional complications. In terms of importance and frequency, we highlight compartment syndrome, phlyctenas and infections. Methodology: a literature search was carried out in MedLine/PubMed with the keywords: "Snake Bite hand Children" and "Snake Bite compartment syndrome". Articles published in the last 10 years (2012 to 2022) were included. Results: the search for articles with the words "Snake Bite hand Children" resulted in 20 articles and the search for the words "Snake Bite compartment syndrome" resulted in 34 articles. After applying the inclusion and exclusion criteria, 30 articles were obtained for the analysis. Conclusions: the pediatric population is more exposed to snake bites and in turn to present more severe lesions. The treatment of compartment syndrome continues to be a subject of debate. Inoculated venom can simulate a compartment syndrome that can be reversed without fasciotomies with proper treatment. Likewise, in the presence of clear symptoms and signs of compartment syndrome, fasciotomies are suggested because of the serious sequelae generated. In the event of the appearance of phlyctenas, careful unroofing of the phlyctenas would be an appropriate treatment. Most authors agree with prophylactic treatment with antibiotic therapy.

Introdução: O envenenamento por mordidas ofídias é reconhecido como um problema de saúde pública pela Organização Mundial da Saúde. A baixa incidência, juntamente com a diversidade de apresentações clínicas, idades, topografias afetadas, bem como os diferentes protocolos da literatura existente sobre alguns aspectos do tratamento, tornam difícil o gerenciamento sistemático desses pacientes. O objetivo deste trabalho é realizar uma revisão sistemática da literatura sobre mordida de cobra em pacientes pediátricos com envolvimento de mãos e membros superiores, com ênfase no gerenciamento de complicações loco-regionais. Em termos de importância e freqüência, destacamos a síndrome compartimental, as flectenas e as infecções. Metodologia: foi realizada uma pesquisa bibliográfica no MedLine/PubMed com as palavras-chave: "Snake Bite hand Children" e "Snake Bite compartment syndrome". Os artigos publicados nos últimos 10 anos (2012 a 2022) foram incluídos. Resultados: a busca de artigos usando as palavras "Snake Bite hand Children" resultou em 20 artigos e a busca das palavras "Snake Bite compartment syndrome" resultou em 34 artigos. Após a aplicação dos critérios de inclusão e exclusão, foram obtidos 30 artigos para análise. Conclusões: a população pediátrica está mais exposta às picadas de cobra e, por sua vez, a lesões mais graves. O tratamento da síndrome compartimental continua a ser motivo de debate. O veneno inoculado pode simular uma síndrome de compartimento que pode ser revertida sem fasciotomias com tratamento apropriado. Da mesma forma, se houver sinais e sintomas claros de síndrome compartimental, são sugeridas fasciotomias por causa das severas seqüelas. Se as flectenas aparecerem, o desenrolamento cuidadoso das flectenas seria um tratamento apropriado. A maioria dos autores concorda com o tratamento profilático com a antibioticoterapia.

The Lived-In Experience and Psychological Recount of Dog Bite VictimsVisiting the Anti-Rabies Clinic in Kashmir: A Qualitative Study

Introduction: There is a necessitated need for canvassing and prioritizing measures towards rabies elimination beyond existing statuesque post-exposure prophylaxis. Moreover, there is a need to characterize the psychological and intrusive experiences of dog-bite victims to portray a picture beyond the public health perspective. To get an expressive understanding of the psychological and lived-in experience ofObjective: dog bite victims' to complement existing concepts. The study was conducted at the anti-rabiesMethod: clinic(ARC) of SMHS hospital which receives animal bite cases from the whole of Kashmir valley. Participants were selected by purposive sampling based on the inclusion criteria, and data saturation was reached with eleven participant interviews. One to one in-depth interviews were conducted with eleven (11) dog bite victims, using a preformed interview guide. Data analysis was performed using Colaizzi's phenomenological method to describe the individualistic experiences faced in peculiar conditions with familiar phenomena embedded in them. Data analysis yielded three overarching themes and nine subthemes viz:-Results: 1.Spiritual and emotional ineffectualness. (Suffering and affliction, Spiritual sulkiness, Emotional emergence) 2. Flashbacks of being hindered and defenseless. (Lack of focus in one's work, lacking the courage to protect, Being shaky) 3. Social and economical implications. (Financial loss, group and peer detachment, preferring isolation) The results of this study showed that dog bite patients experience an unpleasantConclusion: phenomenon in the face of being bitten by the dogs and are subjected to severe psychological pressures that require attention and support of medical professionals, psychologists and government authorities.

Introduction: The ophidian accident is an intoxication caused by the inoculation of venom through the bite of a snake, which generates local and systemic alterations. This event represents an important public health problem in developing countries due to its high frequency and severity. Snakes of the genus Bothrops are responsible for the majority of accidents, and this is partly due to their wide geographic distribution and aggressive behavior when threatened. Acute kidney injury is an important cause of mortality in patients with snake bites of this genus. Purpose: To describe the case of a female patient with bothrops snakebite-induced acute kidney injury. Simultaneously, the most relevant epidemiological data of said entity, its risk factors, the possible pathophysiological mechanisms that explain its genesis, its diagnosis and clinical management are detailed. The importance of its early identification and timely treatment is highlighted. Case presentation: We present the case of a 40-year-old female patient who was admitted to a fourth level of complexity institution due to acute kidney injury and consumption coagulopathy secondary to bothrops snakebite, with the presence of vaginal bleeding and hematuria that progressed to anuria. and hematemesis; requiring transfusion of blood products and renal replacement therapy, measures with which she presented a favorable clinical evolution. Conclusion and discussion: Acute kidney injury associated with the bite of bothrops snakes is a common and life-threatening clinical complication that should not be overlooked. The pathophysiological events responsible for this complication include immunological mechanisms, coagulation disorders, pigmenturia, direct nephrotoxicity, and the inflammatory response with systemic and renal hemodynamic effects. Knowledge of this entity is essential in order to recognize it early and establish its timely treatment in order to reduce its potentially fatal complications.

Ulceras post anestésicas en niños: Dos casos clínicos / Post anesthesia ulcers in children: Two clinical cases

RESUMEN El siguiente articulo describe dos casos clínicos de ulceras traumáticas pos-anestesia en niños, luego de un tratamiento odontológico, en el cual se utilizó la infiltración de anestesia local, como parte del tratamiento terapéutico para la perdida de la sensibilidad del sector a tratar. Los efectos del anestésico continuaron al terminar el tratamiento, lo que estimuló por la falta de sensibilidad la curiosidad en los niños que se succionen o se muerdan el tejido blando, esto provocó lesiones graves en la mucosa oral. La importancia de estas lesiones pos-anestésicas radica en la prevención, es decir que el profesional que atienda pacientes pediátricos, debe prevenir y evitar estas lesiones graves autoinflingidas por el niño, dándole las recomendaciones verbalmente y por escrito a los padres.

ABSTRACT The following article describes two clinical cases of post-anesthesia traumatic ulcers in children, after dental treatment, in which infiltration of local anesthesia was used as part of the therapeutic treatment for the loss of sensitivity of the sector to be treated. The effects of the anesthetic continued at the end of the treatment, which stimulated curiosity in children to suck or bite the soft tissue due to lack of sensitivity, this caused serious lesions in the oral mucosa. The importance of these post-anesthetic injuries lies in prevention, that is, the professional who attends pediatric patients, must prevent and avoid these serious injuries self-inflicted by the child, giving the recommendations verbally and in writing to the parents.

Massive acute ischemic stroke after Bothrops spp. envenomation in southwestern Colombia: Case report and literature review / Accidente cerebrovascular isquémico agudo masivo por veneno de Bothrops spp. en el suroccidente de Colombia: reporte de caso y revisión de la literatura

Bothrops spp. envenomation and its relationship with ischemic stroke has complex pathogenesis. Local effects such as edema, pain, redness, necrosis, and systemic manifestations like coagulation disorders, thrombosis, renal failure, and hemorrhage have been reported. Hemorrhagic stroke is a common neurological complication but ischemic stroke is poorly understood. We present here the case of a 50-year-old male with no comorbidities referred from a rural area in southwest Colombia with a Bothrops spp. snakebite on the left hand. On admission, the patient presented with a deterioration of consciousness and required mechanical ventilation assistance. The MRI showed multiple ischemic areas in the bilateral frontal- temporal and occipital regions. Two months later, the patient had a favorable resolution, although central paresis in the III and VI cranial nerves and positive Babinski's sign persisted. As already mentioned, the pathophysiology of ischemic stroke due to snakebite is complex but the procoagulant activity of the venom components, the hypovolemic shock, the endothelial damage, and the thromboinflammation can explain it, and although it rarely occurs, it should be considered as a complication of ophidian accidents caused by Bothrops spp.

La mordedura de serpientes Bothrops spp. y el ataque cerebrovascular isquémico tienen una patogenia compleja. Se reconocen efectos locales como edema, dolor, enrojecimiento y necrosis, así como manifestaciones sistémicas como trastornos de la coagulación, trombosis, insuficiencia renal y hemorragia, por lo que el accidente cerebrovascular hemorrágico es una complicación neurológica común, pero, en cambio, el accidente cerebrovascular isquémico es poco conocido. Se presenta el caso de un paciente de 50 años, sin comorbilidades, remitido de una zona rural del suroccidente de Colombia debido a la mordedura de una serpiente Bothrops spp. en su mano izquierda. En el momento del ingreso, el paciente presentaba deterioro de la conciencia y requirió asistencia respiratoria mecánica. Mediante resonancia magnética, se observaron múltiples áreas isquémicas bilaterales en la región fronto-temporal y en la occipital. Dos meses después, el paciente había evolucionado favorablemente, pero persistían la paresia en los pares craneales III y VI y el signo de Babinski. La fisiopatología del accidente cerebrovascular isquémico por mordedura de serpiente es compleja. La actividad procoagulante de los componentes del veneno, el choque hipovolémico, el daño endotelial y la tromboinflamación pueden explicar el accidente cerebrovascular isquémico que, aunque raro, debe considerarse como una complicación del accidente ofídico causado por serpientes Bothrops spp.

Venomous animals in Pernambuco: children at risk / Animais peçonhentos em Pernambuco: crianças em risco

Abstract Objectives: to analyze the epidemiological and clinical aspects of accidents caused by venomous animals in children under 15 years old. Methods: a cross-sectional study with an analytical component using secondary data from Centro de Informação e Assistência Toxicológica de Pernambuco (CIATox-PE), (Poison Center in Pernambuco)), in 2017 to 2019. Notifications of accidents caused were included in the studied age group and evaluated the characteristics of poisoning (animal classification, exposure zone, place and time of the occurrence and specific use of serum therapy), and of the patient (sociodemographic variables, clinical condition and evolution). The analysis performed in STATA® 13.1 presents frequency distribution tables and Pearson's chi-square for comparison. Results: of the 2678 notifications, 82,8% were scorpionism and 10, 8% snakebite. The age group of1 to 9 years old (70.5%) and being male (54.1%) were predominant. Most of the cases occurred in urban area (80.9%), in Recife (67.3%), inside the victim's residence (83.9%) and at night (47.3%). The majority (87.1%) were classified as 'mild severity', 10% received antivenom therapy and one died (by scorpionism). Two cases of snakebite in the workplace were registered. Conclusion: there was a high frequency of accidents caused in the urban area, which may be related to the lack of urban planning and sanitary education. The accidents caused among children in the household environment and the suspicion of child labor in the age group of 10 to 14 years old were also highlighted which favors the development and habits of the venomous animal.

Resumo Objetivos: analisar aspectos epidemiológicos e clínicos dos acidentes por animais peçonhentos em menores de 15 anos. Métodos: estudo transversal com componente analítico utilizando dados secundários do Centro de Informação e Assistência Toxicológica de Pernambuco (CIATox-PE), no período de 2017 a 2019. Foram incluídas as notificações dos acidentes na faixa etária estudada e avaliadas características do envenenamento (classe do animal, zona de exposição, local/turno da ocorrência e uso soroterapia específica) e do paciente (variáveis sociodemográficas, gravidade clínica e evolução). A análise realizada no STATA® 13.1 apresenta tabelas de distribuição de frequência e qui-quadrado de Pearson para comparação. Resultados: das 2678 notificações, 82,8% foram de escorpionismo e 10,8% de ofidismo. Predominaram na faixa etária de 1a 9 anos (70,5%) e sexo masculino (54,1%);ocorreram principalmente na zona urbana (80,9%),no Recife(67,3%), na residência da vítima (83,9%), durante horário noturno (47,3%). A maioria (87,1%) foi classificada como de gravidade leve, 10% receberam soroterapia e ocorreu um óbito (escorpionismo). Registraram-se dois casos de ofidismo em ambiente de trabalho. Conclusão: ressaltam-se os acidentes intradomiciliares entre crianças e a suspeita de trabalho infantil na faixa etária de 10 a 14anos.Os acidentes ocorreram sobretudo na zona urbana provavelmente associado à falta de planejamento e educação sanitária que favorece o desenvolvimento e hábitos do animal peçonhento.

Risk factors of acute kidney injury in patients with multiple wasp stings / 中华肾脏病杂志

Objective:To evaluate the risk factors of acute kidney injury (AKI) in patients with multiple wasp stings.Methods:Patients with multiple wasp stings were retrospectively enrolled in Hanzhong Central Hospital from September 2010 to November 2020. Based on whether the patients developed AKI, the patients were divided into AKI group and non-AKI group. The general characteristics and laboratory examinations between the two groups were compared. The logistic regression model was used to analyze the risk factors of AKI.Results:A total of 356 patients with multiple wasp stings were recruited in this study, with 196 males (55.1%). The age was 56.0(45.0, 64.0) years old. There were 59 patients (16.6%) with hypertension and 13 patients (3.6%) with diabetes. There were 51 patients (14.3%) in the AKI group and 305 patients (85.7%) in the non-AKI group. Baseline data and biochemical examinations indicated that the two groups showed significant differences in gender, age, sting sites (systemic or local), sting needles, proportions of gross hematuria, leukocyte count, hemoglobin, creatine kinase, alanine transaminase, aspartate aminotransferase, total bilirubin, proportions of urinary protein, and proportions of urine occult blood (all P<0.05). The multivariate logistic regression analysis results showed that the increasing number of sting needles (every 10 needles increase, OR=1.866, 95% CI 1.289-2.071, P=0.001), gross hematuria ( OR=9.770, 95% CI 2.586-36.910, P=0.001), decreasing hemoglobin (every 1 g/L increase, OR=0.016, 95% CI 0.001-0.355, P=0.009), increasing aspartate aminotransferase (every 100 U/L increase, OR=1.311, 95% CI 1.144-1.502, P<0.001), and increasing total bilirubin (every 10 μmol/L increase, OR=1.200, 95% CI 1.008-1.430, P=0.041) were independent influencing factors of AKI. Conclusions:The increasing number of sting needles, gross hematuria, decreasing hemoglobin, increasing aspartate aminotransferase, and increasing total bilirubin are independent risk factors of AKI in patients with multiple wasp stings.

Objective: to analyze the temporal trend of accidents involving venomous animals in Brazil from 2007 to 2019. Methods: this was a cross-sectional study carried out with data from the Notifiable Health Conditions Information System (SINAN). Prais-Winsten linear regression was used for the temporal analysis. We calculated incidence rates according to sex and age group, relative risk and case fatality ratio. Results: during the study period there were 2,102,657 cases of accidents involving venomous animals. With the exception of snakebite, the remaining accidents showed a rising temporal trend in most regions of the country. Scorpion stings, snake bites and spider bites were responsible for 86% of accidents, mainly affecting male people of working age. Accidents involving snakes (0.4%) and bees (0.3%) had the highest case fatality ratios. Children were the main victims of accidents involving bees, caterpillars and "others". Conclusion: accidents involving venomous animals showed a rising temporal trend for most conditions, as well as different epidemiological profiles.

Mapping of the venomous stingrays of the Potamotrygon genus in the Tietê River, São Paulo Sstate, Brazil

ABSTRACT Background: Freshwater stingrays are fish that have adapted to the rivers and lakes in South America. The expansion of the Potamotrygonidae family in the Paraná River began after the damming of the Sete Quedas Falls, reaching the mouth of the Paranapanema and Tietê rivers approximately 20 years ago via the locks of the hydroelectric power plants. They are not aggressive animals; however, they have one to four stingers on their tails covered by a venom-producing epithelium and can cause severe envenomation in fishermen and bathers if stepped on or manipulated. Methods: We conducted a descriptive, retrospective, and prospective study by monitoring the fishing of the Potamotrygon genus in the lower Tietê River, mapping the location of the rays as a fishery product of professional fishermen and/or recording images of the fish caught. Results: Sixteen stingrays of the Potamotrygon genus were mapped by monitoring fishermen's fish products in the extensive area between the municipalities of Pereira Barreto and Buritama, São Paulo state. Conclusions: The lower Tietê River is fully colonized by freshwater stingrays and this expansion likely continues upstream, reaching various sub-basins of the river. The advancement of these venomous fish in areas where they did not exist previously requires education programs and interaction with the community to avoid serious injuries in bathers and fishermen and the unreasonable extermination of the animals.

Centipede envenomation (Chilopoda): Case report

ABSTRACT Centipedes are venomous arthropods that have an elongated body, divided into many segments, presenting a pair of legs in each segment, adapted pairs of paws that simulate fangs and inject venom causing intense pain, with local erythema and edema, and rarely, blisters and skin necrosis. We present the case of a young woman pricked on her upper lip with intense swelling and local pain and discuss the real danger of envenomation and the therapeutic measures that should be taken.
