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.

Epidemiological study of the bee stings in the state of Bahia, northeastern Brazil, from 2010 to 2019 / Estudo epidemiológico dos acidentes por picada de abelha no estado da Bahia, nordeste do Brasil, de 2010 a 2019

Introduction: envenomation and deaths by bee stings have increased in all regions of Brazil. However, there are few epidemiological studies on them, especially in the states of northeastern Brazil. Objective: to determine the epidemiological characteristics of bee stings in the state of Bahia, Northeastern Brazil, from 2010 to 2019. Methodology: this is a descriptive and analytical epidemiological study conducted through a retrospective survey of secondary data provided by the database of the Notifiable Diseases Information System of the Ministry of Health. Results: between 2010 and 2019, a total of 7,979 cases were analyzed. Incidents were distributed in 356 municipalities, with the highest frequency in the regions of Agreste and Sertão da Bahia. Cases occurred in all months of the investigated years, with a greater occurrence in urban areas, affecting mainly adult men. The anatomical region of the body most affected by the sting was the head and most cases received medical care within 3 hours after the incident. Local manifestations were more frequent than systemic ones. The injuries were predominantly classified as mild and progressed to cure. Conclusions: the high number of cases and their extensive spatial distribution reveal that bee stings may be considered an emerging and neglected public health problem in the state of Bahia.

Introdução: os acidentes e os óbitos causados por picada de abelha têm aumentado em todas as regiões do Brasil. Contudo, existem poucos estudos epidemiológicos sobre acidentes com abelha, principalmente nos estados do Nordeste do Brasil. Objetivo:determinar as características epidemiológicas do acidente por picada de abelha no estado da Bahia, Nordeste do Brasil, de 2010 a 2019. Metodologia: trata-se de um estudo epidemiológico descritivo e analítico realizado por meio de uma pesquisa retrospectiva de dados secundários disponibilizados pelo banco de dados do Sistema de Informação de Agravos de Notificação do Ministério da Saúde. Resultados: entre 2010 e 2019, um total de 7.979 casos foi analisado. Os acidentes foram distribuídos em 356 municípios, com a maior frequência nas regiões do Agreste e do Sertão da Bahia. Os casos ocorreram em todos os meses dos anos investigados, com maior ocorrência em áreas urbanas, afetando principalmente homens adultos. A região anatômica do corpo mais atingida pela picada foi a cabeça e a maioria dos casos recebeu assistência médica até 3 horas após o incidente. As manifestações locais foram mais frequentes do que as sistêmicas. Os agravos foram predominantemente classificados como leve e progrediram para a cura. Conclusões: o elevado número de casos e a sua extensa distribuição espacial revelam que o acidente causado por picada de abelha pode ser considerado um emergente negligenciado problema de saúde pública no estado da Bahia.

Síndrome de Guillain-Barré asociado a accidente apídico: reporte de caso / Guillain-Barré syndrome associated with a bee sting accident: a case report / Síndrome de Guillain-Barré associada a acidente elapídico: relato de caso

El accidente apídico implica un bajo riesgo de morir por reacciones agudas como anafilaxia. Es frecuente que se desconozcan otros riesgos como el hepático y el neurológico. Dentro de las complicaciones menos conocidas está la polineuropatía aguda conocida como Guillain- Barré. La causa más ampliamente descrita es la reacción cruzada entre IgE y la proteína básica de mielina. A continuación, se reporta el primer caso en América Latina sobre la asociación entre Guillain-Barré y accidente por picadura de abejas. En este caso, hay criterios de causalidad como el nexo temporal, la plausibilidad biológica y la coherencia con otros artículos reportados en la literatura médica.

Bee sting accident usually implies a low risk of dying from acute reactions such as anaphylaxis. Other risks such as liver and neurological risks are often unknown. Among the lesser-known complications caused by this type of accident is the acute polyneuropathy known as Guillain-Barré. The most widely described cause is the cross reaction between IgE and myelin basic protein. The article reports the first case in Latin America on the association between Guillain-Barré and a bee sting accident. In this case, there are causality criteria such as temporal link, biological plausibility, and consistency with other articles reported in the medical literature

Caracterización de pacientes alérgicos a picadura de abeja que reciben inmunoterapia / Characterization of allergic patients to bee sting that receive immunotherapy

La alergia al veneno de abejas provoca reacciones de leves a severas con compromiso para la vida. La inmunoterapia con veneno de himenópteros es un tratamiento eficaz y protege a los pacientes alérgicos de sufrir reacciones sistémicas ante nuevas picaduras. Nos propusimos caracterizar los pacientes alérgicos a picaduras de abeja que reciben inmunoterapia. Se realizó un estudio observacional descriptivo de corte longitudinal en pacientes alérgicos a las picaduras de abeja tratados con inmunoterapia de extracto de abeja en el Hospital Universitario General Calixto García de La Habana, Cuba. La muestra fue de 17 pacientes que cumplieron los criterios de inclusión. Usamos técnicas de estadística descriptiva: promedio, probabilidad y puntaje estandarizado, así como técnicas de estadística inferencial tales como Chi cuadrado, verificando asociación significativa entre las variables; el nivel de significación empleado fue del 5 por ciento (p˂0,05). La tercera década de la vida fue la edad promedio de los pacientes. Se observó predominio del sexo masculino y residencia en zona urbana. Alrededor de la mitad de los pacientes tenían rinitis y antecedentes familiares de asma. Todos los pacientes tuvieron reacciones locales, la mayoría se re-expusieron a la picadura; de ellos, solo el 20 por ciento presentaron reacciones alérgicas sistémicas después de la inmunoterapia. Se concluye que la reactividad cutánea al extracto de abeja se redujo con el tratamiento de inmunoterapia(AU)

Allergy to bee venom may cause from mild to severe reactions threatening the patient´s life. Immunotherapy with hymenopter venom is an effective treatment that can protect allergic patients from suffering systemic reactions to new stings. The aim of this study was to characterize allergic patients to bee sting that receive immunotherapy. A descriptive longitudinal observational study was carried out in allergic patients to bee sting receiving immunotherapy with bee extracts in the University Hospital General Calixto García, Havana, Cuba. A sample of 17 patients with inclusion criteria was analyzed. Descriptive statistical techniques were used: mean, probability, standardized score, as well as, inferential statistic techniques such as the Chi square; verifying significant association between variables. The level of signification was 5 percent (p˂0.05). The third decade of life was the average age of the patients in this study; male sex and, urban residents were predominant. Around half of the patients had rhinitis and family history of asthma. All patients had local reactions; most of the patients were re-exposed to stings. Only 20 percent of patients reported systemic allergic reaction after immunotherapy. Skin reactivity to bee extract was reduced with the immunotherapy(AU)

Contribution of molecular diagnosis to bee venom allergic patients with systemic reactions during the build-up phase of bee venom immunotherapy / Contribuição do diagnóstico molecular em doentes alérgicos ao veneno de abelha com reações sistêmicas durante o ultra-rush

Introduction: Bee venom (BV) allergy is one of the most common causes of severe anaphylaxis. Venom immunotherapy (VIT) is considered the most effective treatment, but systemic reactions may occur. This study aimed to characterize the sensitization profile by molecular components of patients with BV anaphylaxis under VIT and to evaluate whether systemic reactions during the build-up phase of VIT protocol are related to different sensitization patterns. Methods: A retrospective study of 30 patients under VIT for 1 year. The group of patients who reacted during the build-up phase (group A) was compared with the group with no reactions (group B). Specific IgE (sIgE) and IgG4 (sIgG4) for BV and recombinants (rApi m1, rApi m2, rApi m3, rApi m5, and rApi m10) were evaluated before and 1 year after VIT. Statistical analysis was performed using GraphPad Prism v5.01. Results: Men accounted for 80% of the sample, and mean age was 47 years (14-74 years). Group A consisted of 10 patients, and group B of 20 patients. Before VIT, sIgE to rApi m1 was detected in 86.7% of patients, rApi m2 in 46.7%, rApi m3 in 16.7%, rApi m5 in 43.3%, and rApi m10 in 70%. Positive results to at least 1 BV allergen were detected in 100%; 73% of patients were sensitized to >1 allergen, and 13.3% to all allergens. The profile of the two groups did not differ significantly before VIT, but group B showed a significant decrease in whole BV extract (p=0.045), rApi m 3 (p=0.017), and rApi m 10 (p=0.021) 1 year after VIT. Regarding sIgG4, there was a significant increase in rApi m1, which was not observed in other allergens, such as rApi m3 and rApi m10. Conclusion: The analysis of a panel of BV recombinants can improve diagnostic sensitivity, when compared to rApi m1 alone. There was no association between systemic reactions during the build-up phase of VIT and molecular sensitization profile. Nevertheless, it is important to study a greater number of patients.

Introdução: A alergia ao veneno de abelha (VA) é uma das causas mais comuns de anafilaxia grave. A imunoterapia com veneno de abelha (VIT) é considerada o tratamento mais eficaz, mas reações sistêmicas podem ocorrer. O objetivo deste estudo foi caracterizar o perfil de sensibilização por componentes moleculares de doentes com anafilaxia a VA e avaliar se reações sistêmicas durante o ultrarush estão relacionadas com diferentes padrões de sensibilização. Métodos: Estudo retrospectivo incluindo 30 doentes submetidos a VIT durante 1 ano. Considerou-se dois grupos: grupo de doentes que reagiu durante o ultra-rush (Grupo A), que foi comparado com o grupo sem reação (Grupo B). Foram avaliadas as IgE (sIgE) e IgG4 (sIgG4) específicas para VA(i1) e componentes moleculares: rApi m1, rApi m2, rApi m3, rApi m5 e rApi m10 antes e 1 ano após VIT. Os testes estatísticos foram realizados com Graph-PadPrism v5.01. Resultados: 80% sexo masculino, média de idade 47 anos (14-74). Grupo A com 10 doentes, Grupo B com 20 doentes. Previamente à VIT, sIgE para rApi m1 foi detectada em 86,7%; rApi m2 em 46,7%; rApi m3 em 16,7%; rApi m5 em 43,3%; e rApi m10 em 70%. Resultados positivos para pelo menos um alergênio de VA foram detectados em 100%. 73% dos doentes eram sensibilizados a mais de um alergênio, e 13,3% a todos os alergênios. Não houve diferenças estatisticamente significativas no perfil dos dois grupos antes da VIT, porém verificouse uma diminuição significativa: p = 0,045; p = 0,017 e p = 0,021 de i1, rApi m3 e rApi m10, respectivamente, no grupo B um ano após VIT. Relativamente à sIgG4, observou-se um aumento significativo de rApi m1, não observado nos restantes alergênios como rApi m3 e rApi m10. Conclusão: A análise de um painel de recombinantes de VA pode melhorar a sensibilidade diagnóstica, quando comparado com rApi m1 isolado. Não se verificou associação entre a ocorrência de reações sistêmicas durante o ultra-rush e o perfil de sensibilização molecular. No entanto, é importante para estudar um maior número de doentes.

Falla multiorgánica secundaria a múltiples picaduras de abeja (Apis mellifera). Reporte de caso / Multiorgan failure secondary to multiple bee stings (Apis mellifera). Case report

Resumen Antecedentes: Las picaduras de abejas producen el mayor número de accidentes en muchos países. Se han descrito manifestaciones sistémicas inusuales tras la exposición al veneno de himenópteros. Con menor frecuencia se han documentado complicaciones neurológicas, infarto del miocardio, rabdomiólisis e insuficiencia renal. Este tipo de reacciones alérgicas sistémicas se producen en 0.3-7.5% de la población. Caso clínico: Varón de 39 años, talador, procedente de zona rural de Comayagua, Honduras, con historia de sufrir múltiples picaduras por abeja (Apis mellifera) acompañado de síncope, con trauma en región frontoparietal bilateral, de 3 h de evolución, fue atendido en servicio de salud en Comayagua y trasladado al Hospital Escuela Universitario, donde se continuó manejo por anafilaxia severa y extracción de múltiples aguijones. Posteriormente inició con estridor laríngeo, cianosis y disnea, por lo que se realizó intubación endotraqueal. Al examen físico se identificó edema facial importante, múltiples lesiones y excoriaciones, patrón respiratorio irregular, picaduras generalizadas, y presencia de hipoventilación en ambos campos pulmonares. Glasgow 13/15, hiperalgesia generalizada. Exámenes de laboratorio mostraron reacción leucemoide, neutrofilia severa, hiperhemoglobinemia, aumento de azoados, enzimas hepáticas elevadas, hipoalbuminemia, trastornos hidroelectrolíticos y acidosis mixta. Posteriormente progresó a rabdomiólisis y falla multiorgánica (hemodinámica, ventilatoria, renal), y falleció 48 h después de su ingreso. Conclusión: El número de picaduras y la cantidad de veneno inoculado son factores predictores de alta mortalidad y baja sobrevida. El traslado de forma oportuna y el manejo multidisciplinario son fundamentales para determinar un buen pronóstico en estos pacientes.

Abstract Background: Bee stings produce the greatest number of accidents in many countries. Unusual systemic manifestations have been described after exposure to Hymenoptera venom. Less frequently, neurological complications, myocardial infarction, rhabdomyolysis and renal failure have been documented. This type of systemic allergic reactions occur in 0.3-7.5% of the population. Case report: A 39-year- old male, logger, from the rural área of Comayagua, Honduras, had a history of suffering multiple bee stings (Apis mellifera) with a syncopal episode, trauma in parietal-forehead bilateral region and 3 hours of evolution. He was treated at a health service in Comayagua and transferred to the University School Hospital, where treatment was continued due to severe anaphylaxis and extraction of multiple stings. Later he began with stridor, cianosis and dyspnea, so endotracheal intubation was performed. Physical examination revealed significant facial edema, multiple lesions and excoriations, irregular respiratory pattern, generalized stings, and the presence of hypoventilation in both lung fields. Glasgow 13/15, generalized hyperalgesia. Laboratory tests showed leukemoid reaction, severe neutrophilia, hyperhemoglobinemia, increased nitrogen levels, elevated liver enzymes, hypoalbuminemia, hydroelectrolytic disorders and mixed acidosis. He later progressed to multiorgan failure and rhabdomyolysis (hemodynamics, ventilatory, renal), and died 48 hours after admission. Conclusion: The number of bites and the amount of poison inoculated are predictive factors of high mortality and low survival. The transfer in a timely manner and multidisciplinary management are essential to determine a good prognosis in these patients.

Late-Onset Post-radiation Lymphedema Provoked by Bee Venom Therapy: A Case Report

Lymphedema is a common complication associated with cancer itself or with cancer treatment. Lymphedema infrequently occurs after drug therapy. Bee venom is one of the materials used in acupuncture, and it has been used in the treatment of a variety of inflammatory diseases including arthritis. We report a 74-year-old male patient with late-onset post-radiation lymphedema provoked by bee venom therapy. He was free of lymphedema for 5 years after the complete remission of prostate cancer which had been treated with transurethral resection and radiation therapy. The patient developed left leg swelling after undergoing bee venom therapy for left hip pain. Computed tomography and lymphoscintigraphy showed lymphedema without tumor recurrence or infection. The lymphatic system was suspected to be injured by bee venom therapy and lymphedema was provoked. Bee venom therapy should be used cautiously in patients prone to lymphedema.

Guillain-barré Syndrome after Multiple Bee Stings

Severe systemic responses including neurologic complications such as myasthenia gravis, myeloradiculopathy, optic neuropathy, parkinsonism, stroke and Guillain-barré syndrome can occur after bee stings. This case describes a 78-year-old female who presented with symptoms of acute progressive bilateral symmetrical weakness in both lower legs after multiple bee stings. Nerve conduction study findings were consistent with acute sensorimotor axonal neuropathy and recovered by treatment with intravenous immunoglobulin. This case highlights that bee stings can result in acute onset Guillain-barré syndrome, although the pathophysiologies of bee venoms need to be investigated accurately.

Antifungal Effects of Bee Venom Components on Trichophyton rubrum: A Novel Approach of Bee Venom Study for Possible Emerging Antifungal Agent

BACKGROUND: Bee venom (BV) has been widely investigated for potential medical uses. Recent inadvertent uses of BV based products have shown to mitigate signs of fungal infections. However, the component mediating the antifungal effect has not been identified. OBJECTIVE: This investigation compares bee venom in its whole and partial forms to evaluate the possible component responsible for the antifungal effect. METHODS: Forty-eight plates inoculated with Trichophyton rubrum were allocated into four groups. The groups were treated with raw BV (RBV), melittin, apamin and BV based mist (BBM) respectively and each group was further allocated accordingly to three different concentrations. The areas were measured every other day for 14 days to evaluate the kinetic changes of the colonies. RESULTS: The interactions of ratio differences over interval were confirmed in groups treated with RBV and BBM. In RBV, the level of differences were achieved in groups treated with 10 mg/100 µl (p=0.026) and 40 mg/100 µl (p=0.000). The mean difference of ratio in groups treated with RBV was evident in day 3 and day 5. The groups that were treated with melittin or apamin did not show any significant interaction. In BBM groups, the significant levels of ratio differences over time intervals were achieved in groups treated with 200 µl/100 µl (p=0.000) and 300 µl/100 µl (p=0.030). CONCLUSION: The the bee venom in its whole form delivered a significant level of inhibition and we concluded that the venom in separated forms are not effective. Moreover, BV based products may exert as potential antifungal therapeutics.

Bee venom stimulation of a lung meridian acupoint reduces inflammation in carrageenan-induced pleurisy: an alternative therapeutic approach for respiratory inflammation

Respiratory inflammation is a frequent and fatal pathologic state encountered in veterinary medicine. Although diluted bee venom (dBV) has potent anti-inflammatory effects, the clinical use of dBV is limited to several chronic inflammatory diseases. The present study was designed to propose an acupoint dBV treatment as a novel therapeutic strategy for respiratory inflammatory disease. Experimental pleurisy was induced by injection of carrageenan into the left pleural space in mouse. The dBV was injected into a specific lung meridian acupoint (LU-5) or into an arbitrary non-acupoint located near the midline of the back in mouse. The inflammatory responses were evaluated by analyzing inflammatory indicators in pleural exudate. The dBV injection into the LU-5 acupoint significantly suppressed the carrageenan-induced increase of pleural exudate volume, leukocyte accumulation, and myeloperoxidase activity. Moreover, dBV acupoint treatment effectively inhibited the production of interleukin 1 beta, but not tumor necrosis factor alpha in the pleural exudate. On the other hand, dBV treatment at non-acupoint did not inhibit the inflammatory responses in carrageenan-induced pleurisy. The present results demonstrate that dBV stimulation in the LU-5 lung meridian acupoint can produce significant anti-inflammatory effects on carrageenan-induced pleurisy suggesting that dBV acupuncture may be a promising alternative medicine therapy for respiratory inflammatory diseases.

Severe Ulnar Nerve Injury After Bee Venom Acupuncture at a Traditional Korean Medicine Clinic: A Case Report

This case report describes a severe nerve injury to the right ulnar nerve, caused by bee venom acupuncture. A 52-year-old right-handed man received bee venom acupuncture on the medial side of his right elbow and forearm, at a Traditional Korean Medicine (TKM) clinic. Immediately after acupuncture, the patient experienced pain and swelling on the right elbow. There was further development of weakness of the right little finger, and sensory changes on the ulnar dermatome of the right hand. The patient visited our clinic 7 days after acupuncture. Electrodiagnostic studies 2 weeks after the acupuncture showed ulnar nerve damage. The patient underwent steroid pulse and rehabilitation treatments. However, his condition did not improve completely, even 4 months after acupuncture.

Effects of Emollient Containing Bee Venom on Atopic Dermatitis: A Double-Blinded, Randomized, Base-Controlled, Multicenter Study of 136 Patients

BACKGROUND: Atopic dermatitis (AD) is a common, complex disease that follows a chronic relapsing course and significantly affects the quality of life of patients. Skin barrier dysfunction and inflammatory processes induce and aggravate this skin condition. Proper use of an emollient for hydration is a keystone of AD treatment. Bee venom is known to have anti-inflammatory effects and has been widely used in traditional medicine to treat various inflammatory disorders. OBJECTIVE: To find out the beneficial effect of an emollient containing bee venom in the treatment of patients with AD. METHODS: This study included 136 patients with AD who were randomized to receive either an emollient containing bee venom and silk-protein or a vehicle that was identical except for the bee venom for 4 weeks. The patients were instructed to apply the emollient twice daily on their entire body and not to use other medications, including topicals, during the course of the study. The eczema area and severity index (EASI) score, transepidermal water loss, and visual analogue scale (VAS) score of itching were evaluated at the first visit and after 2 and 4 weeks. The investigator global assessment was evaluated at 2 and 4 weeks after the application of emollient containing bee venom or vehicle. RESULTS: Patients applying emollient containing bee venom showed significantly lower EASI score and VAS value compared to patients applying emollient without bee venom. CONCLUSION: Emollient containing bee venom is a safe and effective option for patients with AD.

AKI and Takotsubo Cardiomyopathy after Bee Venom-induced Anaphylaxis / 대한내과학회지

Bee venom-induced anaphylaxis usually causes urticaria, angioedema, respiratory distress, nausea, and vomiting. Occasionally, it leads to unusual complications such as acute myocardial infarction, takotsubo cardiomyopathy, arrhythmia, rhabdomyolysis, intravascular hemolysis, and acute kidney injury. Renal complications are rare, and there are only two cases of acute kidney injury associated with rhabdomyolysis due to multiple bee stings reported in Korea. We report a 67-year-old woman who presented at our emergency department with confusion, respiratory distress, and dizziness after multiple bee stings. She was diagnosed with anaphylactic shock. There was acute kidney injury associated with rhabdomyolysis and heart failure related to takotsubo cardiomyopathy, all of which indicated unusual and fatal complications. Her condition worsened, almost requiring intubation and mechanical ventilation. However, the patient recovered without cardiac or renal complications within 30 days of therapy with hydration and diuretics.

Serum sickness reaction with skin involvement induced by bee venom injection therapy

Bee venom injection therapy is an alternative treatment sometimes used for chronic inflammatory diseases, including rheumatoid arthritis and multiple sclerosis, to reduce pain. Several chemical components of bee venom have anti-inflammatory effects, and apitoxin, one of the mixed components, has been used for pain prevention therapy. However, there have been no large-scale investigations regarding the efficacy or side effects or apitoxin. In this study, a case of serum sickness reaction that developed after receiving bee venom injection therapy is reported.

A Case of Steven-Johnson Syndrome after Live Bee Acupuncture (Bong-Chim)

Bee stings can cause various skin reactions that usually resolve over several days; however, in some patients the venom acts as an allergen, causing a severe immunological response such as anaphylaxis. Bee stings can also induce chronic inflammation because the barbed stinging apparatus and venom sacs, along with the nerve plexus, can lodge in the skin. Chronic non-specific low back pain is the most common medical problem for which patients seek complementary and alternative medical treatment, including bee venom acupuncture. Bee venom acupuncture involves injecting diluted bee venom into acupoints and is used for arthritis, pain, and rheumatoid diseases. Here we report a 75-year-old man with acute urticaria and skin eruption with eosinophilia and interstitial pneumonia 6 weeks later after receiving 5 times bee venom acupuncture.

Acute lung injury after bee sting acupuncture

Bee stings can cause severe adverse reactions. There have been no cases of acute lung injury induced by bee sting acupuncture. We report a case of a 52-year-old male who required high flow oxygen therapy because of acute lung injury by bee sting acupuncture. The patient had been treated with live bee sting acupuncture by himself for knee pain. After self-injections of live bee sting, he immediately presented with generalized urticaria that remitted within 3 hours after taking an oral antihistamine. Ten days later, he visited our emergency department due to dyspnea and dizziness. He was diagnosed with acute lung injury by bee sting acupuncture based upon a history of symptom onset after exposure to the allergen and clinical test results. This case emphasizes that practitioners should consider potential risks of delayed-onset adverse reactions induced by bee sting acupuncture.

Síndrome compartimental en miembros superiores por picadura de abejas: reporte de caso / Compartment syndrome of the upper limbs after bee sting: Case report

Introducción: El síndrome compartimental en la extremidad superior es considerado una urgencia. Puede generar necrosis y pérdida de la funcionalidad de la mano. El principal tratamiento es con fasciotomías. Sin embargo, existen posibilidades terapéuticas que pueden ayudar o evitar la cirugía, siempre y cuando exista la posibilidad rápida de realizar una fasciotomía si la terapia conservadora fracasa. Objetivo:Evaluar la respuesta clínica y la seguridad al tratamiento con bloqueo del ganglio estrellado y analgesia epidural cervical en una paciente con síndrome compartimental de ambos miembros superiores. Métodos y materiales:Estudio descriptivo longitudinal prospectivo tipo reporte de caso en una paciente con síndrome compartimental de ambos miembros superiores en la que se realizó un bloqueo del ganglio estrellado y analgesia epidural cervical como medida en el tratamiento de su enfermedad. Se realizó un seguimiento durante 7 días. Se evaluaron la recuperación de la sensibilidad y de la movilidad en ambas manos, la intensidad del dolor y la mejoría de la cianosis distal bilateral. Resultados:La paciente evoluciona satisfactoriamente, se evidencia recuperación de la sensibilidad y movilidad en ambas manos, con adecuado control del dolory mejoría de la cianosis distal de manera inmediata y bilateral. Conclusiones: El bloqueo simpático y la analgesia epidural cervical son una alternativa terapéutica en el tratamiento integral del síndrome compartimental siempre y cuando el paciente reciba una monitorización continua de los signos de alarma y tenga la disponibilidad inmediata de un cirujano de mano para realizar fasciotomías en caso de que el tratamiento intervencionista falle.

Introduction:The upper limb compartment syndrome is considered an emergency. It may cause necrosis and loss of functionality of the hand. The principal treatment is fasciotomies. However, there are therapeutic possibilities that may help or avoid surgery, provided there is always the option to do a fasciotomy when conservative treatment fails. Objective: To assess the clinical response and treatment safety with stellate ganglion block and cervical epidural anesthesia in a patient with compartment syndrome of both upper limbs. Methods and materials: Descriptive longitudinal prospective study in a case report format, of a patient with compartment syndrome of both upper extremities that underwent a stellate ganglion block and cervical epidural anesthesia for treating her condition. The patient was followed for 7 days. The recovery of sensitivity and the mobility were assessed on both hands, in addition to pain intensity and bilateral distal cyanosis improvement. Results:The patient evolved satisfactorily with evidence of recovery of sensitivity and mobility in both hands, adequate pain control and immediate and bilateral improved distalcyanosis. Conclusions: Sympathetic block and epidural cervical analgesia are a treatment option for the comprehensive approach of the compartment syndrome, as long as the patient receives constant monitoring of any alarm signs and a surgeon is immediately available to do fasciotomies if the intervention therapy fails.

Hymenoptera venom anaphylaxis in adult Korean: a multicenter retrospective case study

PURPOSE: We investigated the causes, clinical features, and risk factors of bee venom anaphylaxis in Korea. METHODS: The medical records of the diagnosis of anaphylaxis during a 5-year period from the 14 hospitals in Korea have been retrospectively reviewed. Cases of bee venom anaphylaxis were identified among anaphylaxis patients, and subgroup analyses were done. RESULTS: A total of 291 patients were included. The common cause of bee species was vespid (24.6%) in bee venom anaphylaxis, followed by honeybee and vespid (8.8%), apitherapy (7.7%), and honeybee (2.0%), although the causative bee species were commonly unknown (56.9%). The severity of anaphylaxis was mostly mild-moderate (72.9%), and common clinical manifestations included cutaneous (80.6%), cardiovascular (39.2%), respiratory (38.1%), and gastrointestinal (13.1%) symptoms. Portable epinephrine auto-injectors were prescribed to 12.1% of the patients. Subject positive to both vespid and honeybee showed more severe symptoms and higher epinephrine use (P<0.05). The severity was significantly associated with older age, but not with gender, underlying allergic disease, or family history. Apitherapy-induced anaphylaxis showed a higher rate of hospitalization and epinephrine use than bee sting anaphylaxis (P<0.05). CONCLUSION: Vespid is the most common cause of bee venom anaphylaxis in Korea. It is suggested that positivity to honeybee and vespid may be associated with more severe symptoms.

Potentiation of a novel palladium (II) complex lethality with bee venom on the human T-cell acute lymphoblastic leukemia cell line (MOLT-4)

Background : Although honeybee venom (BV) has been reported to induce apoptosis in different types of cancerous cells, its synergistic effects with customary anti-cancer drugs remain largely unknown. In the present study, we evaluated the cytotoxic effect of BV alone (as a natural product) and the synergistic cytological effects of this component in combination with [Pd (bpy) (Pi-Pydtc)]NO3 - a novel palladium complex on human T-cell lymphoblastic leukemia cells. To investigate the cytotoxic effect of the BV alone and in combination with palladium complex on MOLT-4 cells MTT assay was performed. In order to determine the apoptotic effects of BV separately and in combination with Pd (II) complex on these cells and its ability to induce apoptosis, morphological examination, flowcytometric analysis and caspase-3 colorimetric assay were done. Results : We found that BV induced morphological changes, namely nuclear shrinkage, and inhibited MOLT-4 cell proliferation; both effects were dose- and time-dependent. Flow cytometry by Annexin-V antibody demonstrated that BV induced apoptosis in MOLT-4 cells. Furthermore, BV induced apoptosis independently of caspase-3 in these cells. In addition, we proved a clear synergistic effect of BV on [Pd (bpy) (Pi-Pydtc)]NO3. The apoptotic pathway activated by BV in combination with Pd complex was caspase-3-dependent. Conclusions : These observations provide an explanation for the anti-proliferative properties of BV, and suggest that this agent may be useful for treating lymphoblastic leukemia alone or in combination with chemotherapy drugs pending further investigations on animal models as preclinical tests.(AU)

Potentiation of a novel palladium (II) complex lethality with bee venom on the human T-cell acute lymphoblastic leukemia cell line (MOLT-4)

Background : Although honeybee venom (BV) has been reported to induce apoptosis in different types of cancerous cells, its synergistic effects with customary anti-cancer drugs remain largely unknown. In the present study, we evaluated the cytotoxic effect of BV alone (as a natural product) and the synergistic cytological effects of this component in combination with [Pd (bpy) (Pi-Pydtc)]NO3 - a novel palladium complex on human T-cell lymphoblastic leukemia cells. To investigate the cytotoxic effect of the BV alone and in combination with palladium complex on MOLT-4 cells MTT assay was performed. In order to determine the apoptotic effects of BV separately and in combination with Pd (II) complex on these cells and its ability to induce apoptosis, morphological examination, flowcytometric analysis and caspase-3 colorimetric assay were done. Results : We found that BV induced morphological changes, namely nuclear shrinkage, and inhibited MOLT-4 cell proliferation; both effects were dose- and time-dependent. Flow cytometry by Annexin-V antibody demonstrated that BV induced apoptosis in MOLT-4 cells. Furthermore, BV induced apoptosis independently of caspase-3 in these cells. In addition, we proved a clear synergistic effect of BV on [Pd (bpy) (Pi-Pydtc)]NO3. The apoptotic pathway activated by BV in combination with Pd complex was caspase-3-dependent. Conclusions : These observations provide an explanation for the anti-proliferative properties of BV, and suggest that this agent may be useful for treating lymphoblastic leukemia alone or in combination with chemotherapy drugs pending further investigations on animal models as preclinical tests.
