INTRODUCTION: In the American continent, accidents caused by honeybees are a public health problem due to the high incidence and severity of the cases. Despite its medical importance, there are few epidemiological studies on this topic in Brazil, especially referring to the Northeastern states. The present study aims to describe the epidemiological features of honeybee envenomation cases in the state of the Rio Grande do Norte, Northeastern Brazil, from 2007 to 2014. METHODS: Data were collected from the Notifiable Diseases Information System database of the Health Department of Rio Grande do Norte. RESULTS: We analyzed a total of 2,168 cases. Cases occurred in all months of the years studied, reaching higher frequencies from June to October. Most incidents happened in urban areas and involved men, with victims aged between 20 and 39 years. Victims were mainly stung on the head and hand, and they received medical care predominantly within 3 hours after the injury. Local manifestations were more frequent than systemic ones. Clinically, most cases were mild and progressed to cure. CONCLUSION: The high number of honeybee sting cases shows that Rio Grande do Norte may be an important risk area for such injury.

RESUMO: Introdução: No continente americano, os acidentes causados por abelhas são um problema de saúde pública devido à alta incidência e severidade dos casos. Apesar de sua importância médica, há poucos estudos epidemiológicos sobre esse tema no Brasil, especialmente referentes aos estados do Nordeste. O presente estudo tem como objetivo descrever as características epidemiológicas dos casos de envenenamento por abelhas no estado do Rio Grande do Norte, no Nordeste do Brasil, de 2007 a 2014. Metodologia: Os dados foram coletados da base de dados do Sistema de Informação de Agravos de Notificação da Secretaria Estadual de Saúde do Rio Grande do Norte. Resultados: Um total de 2.168 casos foram analisados. Os casos mostraram distribuição em todos os meses dos anos estudados, com maior frequência de junho a outubro. A maioria dos casos ocorreu em áreas urbanas e envolveu homens, com vítimas entre 20 e 39 anos de idade. As vítimas foram principalmente picadas na cabeça e na mão, e receberam assistência médica predominantemente dentro de 3 horas após serem picadas. As manifestações locais eram mais frequentes do que as sistêmicas. Clinicamente, a maioria dos casos foi leve e progrediu para cura. Conclusão: O alto número casos de picadas de abelhas mostra que o Rio Grande do Norte pode ser uma importante área de risco para tal incidente.

This case report describes a massive honey bee envenomation in a 14-month-old male Belgian Malinois dog from St. Kitts, West Indies. Acute and delayed onsets of hemolytic anemia, echinocytosis, spherocytosis, thrombocytopenia, hemoglobinemia, and hemoglobinuria developed following envenomation. The dog recovered after treatment with glucocorticoids and supportive therapy. Spherocytosis, hemolysis, and thrombocytopenia in patients with massive bee envenomation are likely due to the direct toxic effects of the primary components of bee venom, melittin and phospholipase A2 (PLA2 ). Mellitin causes hemolysis by forming large pores in erythrocytes resulting in leakage of hemoglobin and also causes spectrin stiffening and resultant echinocyte and spherocyte formation. Melittin also stimulates PLA2 , a hydrolase that causes echinocytosis and spherocytosis, in vivo and in vitro, and mitochondrial breakdown in platelets. However, delayed manifestations could be attributed to immune-mediated mechanisms from the generation of antibodies against damaged erythrocytes and platelet membrane proteins.

INTRODUCTION: We evaluated the epidemiological and clinical profile of reported cases of bee sting incidents in Santa Catarina, Brazil. METHODS: This retrospective cohort study included all reported cases of bee sting incidents among the population of Santa Catarina from 2007 to 2017. RESULTS: In total, 8,912 cases were reported, corresponding to an overall rate of 12.3/100,000 population. The mean age was 29,8 years with 60.2% men. The lethality rate was 0.2%. CONCLUSIONS: Santa Catarina has a high incidence rate of bee stings, which is higher than the national average. The data presented in this study may be underestimated.

Envenoming syndrome is a systemic toxic reaction to the inoculation of large volume of insect venom, typically after a swarm attack from bees. Africanized honey bees are notorious for their aggressive nature, and human deaths resulting from Africanized honey bee attacks are consistently reported. Whereas anaphylaxis is the most common lethal mechanism of injury, delayed deaths can also occur as a consequence of severe venom toxicity with resultant end organ damage. Acute renal failure complicating massive envenomation is a rare but potentially fatal outcome after Africanized honey bee attack and may be heralded by laboratory evidence of rhabdomyolysis.

We describe three clinical cases of Surinamese children with rhabdomyolysis with diverse clinical presentation and course. The first patient had rhabdomyolysis because of toxins caused by multiple beestings and developed acute kidney injury. The other two patients had rhabdomyolysis following acute infection with chikungunya and influenza A/H1N1 virus. These cases emphasize that the diverse etiology of rhabdomyolysis should be considered in children in tropical settings.

INTRODUCTION: Hymenoptera venom allergy is associated with significant morbidity and deterioration in health-related quality of life, and risk of fatal systemic reactions. Although venom immunotherapy is safe and the only effective treatment in allergic individuals, some patients prefer not to pursue this treatment. Since 2011, when the 50% reimbursement was stopped, patients must fully support the cost of immunotherapy. This study aimed to ascertain the reasons why patients decline immunotherapy. MATERIAL AND METHODS: A medical records review of all patients proposed to receive venom immunotherapy at an Allergy and Clinical Immunology Department in Porto, Portugal, between 2006 and 2015, followed by a phone interview to patients refusing treatment. RESULTS: A total of 83 subjects were enrolled, with a mean (± SD) age of 44.4 (14.7) years and 55 (66%) males; 27 refused venom immunotherapy between 2006 and 2015. Nineteen were interviewed and 14 of those stated price as the main reason for declining treatment. The only identified risk factor associated with immunotherapy refusal was being proposed after 2011 (OR: 3.29; 95% CI: 1.12 - 9.68; p = 0.03). DISCUSSION: The number of patients refusing venom immunotherapy doubled since reimbursement was withdrawn. Price was identified as the major obstacle to treatment completion. Immunotherapy proposal after reimbursement was stopped was associated with a 3-fold increase in the risk of refusing treatment. CONCLUSION: These findings show how economic decisions may have a detrimental effect on patient care, as immunotherapy refusal left them exposed to an avoidable life-threatening risk.
Introdução: A alergia a veneno de himenópteros está associada a uma significativa morbilidade e diminuição da qualidade de vida, bem como a risco de reações alérgicas fatais. Apesar da imunoterapia com veneno de himenópteros ser um tratamento seguro e o único eficaz nesta patologia, alguns doentes decidem não o realizar. Desde 2011, quando a comparticipação de 50% terminou, o custo da imunoterapia é totalmente suportado pelos doentes. Este trabalho pretendeu identificar os motivos da recusa desta terapêutica. Material e Métodos: Revisão dos registos clínicos de todos os doentes propostos para imunoterapia com veneno de himenópteros num serviço de Imunoalergologia, no período 2006 - 2015, seguida de entrevista telefónica aos que a recusaram. Resultados: Foram incluídos 83 doentes, com uma idade média (± DP) de 44,4 (14,7) anos. Cinquenta e cinco (66%) eram homens; 27 recusaram imunoterapia entre 2006 e 2015. Dezanove foram entrevistados e 14 identificaram o preço como principal motivo de recusa. O único fator de risco identificado para a recusa de imunoterapia foi ser proposta depois de 2011 (OR: 3,29; 95% CI: 1,12 9,68; p = 0,03). Discussão: O número de doentes a recusar imunoterapia duplicou desde que a comparticipação foi retirada. O preço foi o principal obstáculo à realização do tratamento. Ser proposto após o término da comparticipação do tratamento aumentou em três vezes o risco de recusa. Conclusão: Estes achados revelam o impacto negativo de uma decisão económica na saúde e segurança destes doentes, já que a recusa da imunoterapia os manteve expostos a um risco de vida evitável.

Accidents related to Africanized honey bees are growing globally and are associated with multiple stings owing to the aggressive behavior of this species. The massive inoculation of venom causes skin necrosis and rhabdomyolysis leading to renal failure. Anaphylactic manifestations are more common and are treated using well-defined treatment protocols. However, bee venom-induced toxic reactions may be serious and require a different approach. We report the case of a 3-year-old child, which would help clinicians to focus on the treatment approach required after an incident involving multiple bee stings.

Bee stings can cause severe reactions and have caused many victims in the last years. Allergic reactions can be triggered by a single sting and the greater the number of stings, the worse the prognosis. The poisoning effects can be systemic and can eventually cause death. The poison components are melitin, apamin, peptide 401, phospholipase A2, hyaluronidase, histamine, dopamine, and norepinephrine, with melitin being the main lethal component. Acute kidney injury (AKI) can be observed in patients suffering from bee stings and this is due to multiple factors, such as intravascular hemolysis, rhabdomyolysis, hypotension and direct toxicity of the venom components to the renal tubules. Arterial hypotension plays an important role in this type of AKI, leading to ischemic renal lesion. The most commonly identified biopsy finding in these cases is acute tubular necrosis, which can occur due to both, ischemic injury and the nephrotoxicity of venom components. Hemolysis and rhabdomyolysis reported in many cases in the literature, were demonstrated by elevated serum levels of indirect bilirubin and creatine kinase. The severity of AKI seems to be associated with the number of stings, since creatinine levels were higher, in most cases, when there were more than 1,000 stings. The aim of this study is to present an updated review of AKI associated with bee stings, including the currently advised clinical approach.

In the American continent, honeybee envenomation is a public health problem due to the high incidence and severity of the cases. Despite its medical importance, there is a lack of epidemiological studies on this topic in Brazil, especially referring to the Northeastern states. The present study has aimed to describe the epidemiological features of honeybee envenomation cases in the state of the Ceará, Northeastern Brazil, from 2007 to 2013. Data were collected from the Injury Notification Information System database of the Health Department of Ceará. A total of 1,307 cases were analyzed. Cases were shown to be distributed in all the months of the studied years, reaching higher frequencies in August. The majority of cases occurred in urban areas and involved men aged between 20 and 29 years. Victims were mainly stung on the head and torso, and they received medical assistance predominantly within 3 hours after being stung. Local manifestations were more frequent than systemic ones. Most cases were classified as mild and progressed to cure. The high number of honeybee sting cases shows that Ceará may be an important risk area for such injuries. Moreover, the current study provides data for the development of strategies to promote control and prevention of bee stings in this area.

BACKGROUND: Gramineae bee-collected pollen is identified as being at the origin of allergic accidents but the biological potency of Gramineae bee-collected pollen is not well known. Cereal grasses (e.g., Zea) and European wild forage grasses (FG) are contained in bee-collected pollen. METHOD: In this experiment, Zea-mass and FG-mass were identified in bee pollen mass and the proportion of Zea and of FG was calculated using the bee pollen melissopalynology spectrum. Skin reactivity to Zea and to FG were assessed by measuring wheal diameters (W) from skin prick tests using three serial dilutions of bee-collected pollen on 10 allergic patients to Gramineae, in order to calculate the relationship between Zea mass (Masszea) or FG mass (MassFG) in bee pollen and skin reactivity. RESULTS: The linear function Log10(WFG) = 0.24(Log10(MassFG)) + 0.33 (R = 0.99) was established using a bee pollen sample with 0.168 mg of FG pollen per mg. The linear function Log10(Wzea) = 0.23(Log10(Masszea)) + 0.14 (R = 0.99) was established using a bee pollen sample with 0.983 mg of Zea pollen per mg. Gramineae allergens seem to be little altered by bee secretions. Gramineae bee pollen retains its allergenic capacity but it depends on the members of the Gramineae family. CONCLUSIONS: To our knowledge this is the first time it has been shown that skin reactivity to Gramineae is proportional to the absolute Gramineae mass contained in the bee-collected pollen and that it depends on the members of the Gramineae family

Envenoming syndrome from Africanized bee stings is a toxic syndrome caused by the inoculation of large amounts of venom from multiple bee stings, generally more than five hundred. The incidence of severe toxicity from Africanized bee stings is rare but deadly. This report reveals that because of the small volume of distribution, having fewer stings does not exempt a patient from experiencing an unfavorable outcome, particularly in children, elderly people or underweight people.
A síndrome de envenenamento por ferroadas de abelhas africanizadas é causada pela inoculação de uma grande quantidade de peçonha por múltiplas ferroadas de abelhas, geralmente acima de quinhentas. A incidência de uma intoxicação severa por ferroadas de abelhas africanizadas é rara, porém letal. Este relato de caso aponta que, devido a um menor volume de distribuição do veneno, um número menor de ferroadas por abelhas africanizadas não exime o paciente de apresentar envenenamentos com desfecho desfavorável, principalmente em crianças, idosos e pessoas com baixo peso.
