ABSTRACT

Las miasis humanas son ectoparasitosis causadas por larvas de varias especies de moscas que producen distintas formas clínicas, afectan piel, cavidades y heridas. Estas prevalecen en regiones tropicales. Se presenta un caso de miasis foruncular en un hombre de 32 años, turista, infestado en una zona tropical húmeda de la región costera del Pacífico del Ecuador. Acude a consulta con un cuadro clínico de 30 días de evolución, y refiere picadura de insecto que creció hasta formar elevación indurada prurítica, no dolorosa, en piel de flanco izquierdo del abdomen. Al examen físico se observó una lesión foruncular de 3 x 2 cm rodeada de placa eritematosa con el centro abierto observándose un agujero central que descargaba un líquido sero-sanguinolento con movimientos. Por extracción manual se obtuvo una sola larva que por sus características externas se identificó como Dermatobia hominis. El resto del examen físico y exámenes de laboratorio fueron normales. Las actividades turísticas o de trabajo a estas zonas tropicales expone a las personas al riesgo de contraer miasis, por ende, es necesario información y medidas de prevención(AU)


Human myases are ectoparasitic infections caused by larvae of several fly species. They present various clinical manifestations, affecting the skin, cavities and wounds. Myases prevail in tropical regions. A case is presented of furuncular myasis in a male 32-year-old tourist infected in a humid tropical area from the Pacific coastal region of Ecuador. The patient presented with a clinical status of 30 days' evolution, reporting an insect bite that grew to form a painless indurated pruritic nodule on the skin of his left flank of the abdomen. Physical examination found a 3 x 2 cm furuncular lesion surrounded by erythematous plaque and an open center which discharged a serosanguineous fluid with movement. A single larva was obtained by manual extraction, which was identified as Dermatobia hominis based on its external characteristics. The remaining physical examination and laboratory tests were normal. Tourist and work activities in these tropical areas expose people to the risk of contracting myasis. Information and prevention measures are therefore necessary(AU)

ABSTRACT

Abstract Bee venom is a natural toxin composed of several peptides. Massive envenoming causes severe local and systemic reactions. We report two cases of severe bee envenomation, of which one was fatal. We also describe clinical characteristics and immune markers. Both victims suffered from respiratory distress, renal failure, rhabdomyolysis, and shock. They required invasive mechanical ventilation, vasoactive drugs, and renal replacement therapy. Moreover, serum levels of chemokines, cytokines, and cell-free circulating nucleic acids demonstrated an intense inflammatory process. Massive envenoming produced systemic injury in the victims, with an uncontrolled inflammatory response, and a more significant chemotactic response in the fatal case.

ABSTRACT

Abstract Insect bites and bite wounds are quite common and most often have mild repercussions in humans. Statistics on the incidence of accidents caused by insects are not available, and the skin reactions after the bites are not always known. The authors present two cases of patients with hemorrhagic blisters on their hands after tabanidae bites and discuss the factors that cause the problem and the importance of the differential diagnosis of blisters with hemorrhagic content on human skin.

ABSTRACT

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)

ABSTRACT

Resumen Los himenópteros es una de las clasificaciones de los insectos, constituida por principalmente tres tipos, la abeja, la avispa y la hormiga de fuego, que provocan picaduras con veneno, generando desde efectos locales hasta sistémicos, con repercusiones leves o mortales sino reciben una atención médica oportuna. Las reacciones sistémicas son dependientes de la respuesta inmunológica, así como de la cantidad de las picaduras. Se presentaran dos casos de fallecimiento a causa de accidente por himenópteros tipo abejas, diagnosticados por la historia médicolegal, hallazgos de autopsia relacionado al efecto sistémico del veneno de las abejas y circunstancias relacionadas a la muerte.


Abstract Hymenoptera is one of the classifications of insects, consisting mainly of three types, the bee, the wasp and the fire ant, which cause pitting with venom generating from local to systemic effects, with slight or fatal repercussions but receive timely medical attention. Systemic reactions are dependent on the immune response, as well as the number of bites. There will be two cases of death due to an accident by hymenopterans type bees, diagnosed by medical-legal history, autopsy findings related to the systemic effect of bee venom and circumstances related to death will be presented.

ABSTRACT

ABSTRACT: 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.

ABSTRACT

ABSTRACT Background: Studies related to infectivity status of insect vectors are seen as necessities in understanding the epidemiology of vector-borne diseases and planning effective control measures. This study assessed the infectivity ofSimulium damnosum s.l. around Owena River as well as evaluated therapeutic coverage of Ivermectin distribution in the area. Method: Human landing sampling method was used to collect adult flies on human attractants from 07:00 to 18:00 for two consecutive days a month for three months (July 2016 - September 2016). Parity assessment was conducted to determine the age of fly populations. Parous flies were further dissected to detect the presence or absence ofOnchocerca larvae. Biting rates and transmission potentials were calculated using standard methods. A quantitative survey was carried out to determine the therapeutic coverage and compliance to ivermectin treatment for the control of Onchocerciasis in the study area using standard household coverage questionnaires. Results: A total of 914 adult female flies were collected during the study period. The daily biting rate (DBR) varied from 146 fly per man day (FMD) in July to 162.5 FMD in August. The monthly biting rate (MBR) was lowest in September (2170 bites per man per month) but highest in August (3358.3 bites per man per month). MBD ranged from 13.23 fly per man hour (FMH) in July to 14.77 FMH in August. The results indicated that the majority of the flies collected at the sampling points were nulliparous [685 (74.95%)] while others were parous [229 (25.05%)]. The biting activity of the flies showed a marked decrease in population in August compared to July which later increased in September. Infection rates varied from 2 (0.7%) in July to 7 (2.2%) in August while the infectivity rate during the study ranged from zero (July and September) to 3 (1.0%) in August. Conclusion: Despite the years of treatment of onchocerciasis in Owena community, there were still some infective flies capable of transmitting O. volvolus. This could be due to the low rate of therapeutic coverage as a result of non-compliance in the community for various reasons earlier stated.

ABSTRACT

Abstract: Human, dog, and cat fleas, as well as bedbugs, feed by biting their victims, causing acute prurigo, which is aggravated in sensitized victims (papular urticaria). The lesions appear in the classic "breakfast, lunch, and dinner" pattern. There are two main explanations: the parasites "map" the skin area in search of the best places to bite, and their removal when victim scratches, and then reattach to the skin. Treatments aim to control pruritus, as well as hypersensitivity reactions when necessary. Prevention is based on environmental control measures. The "breakfast, lunch, and dinner" sign is a definitive marker for diagnosis and the parasite´s identification and control.

ABSTRACT

Abstract: Sclerodermus sp. is an aculeate insect (Hymenoptera: Bethylidae), measuring 2-4 mm in length. It is a parasitoid and needs termites as hosts to complete its life cycle. It is found in a wide variety of woods and may accidentally sting humans who come near affected wooden objects. A 50-year-old woman presented two episodes of intense pruritic lesions. Clinical diagnosis of insect bite was doubtful since there were no pets at home, lesions had not started during summer and the patient denied rural activities. During a night episode of itching, the patient examined her bed and found 8 insects likely to be responsible for the bites. Scanning electron microscopy revealed typical features of a female of the genus (wingless and with multiple stingers at the lower end of the abdomen).

ABSTRACT

Abstract: A 59-year-old atopic man referred to for the onset of a diffused itching papular-purpuric eruption involving his trunk and legs but without systemic symptoms. History revealed that he started feeling itching after spending few hours in his basement. Direct examination of the environmental dust (www.edpa.it) showed high level of infestation of Solenopsis fugax, a small Myrmicinae ant. The skin eruption completely healed without scarring in 2 weeks. Specific disinfestation measures were performed and the patient did not comply of any recurrence during a 6-months follow-up.

ABSTRACT

Abstract 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.

ABSTRACT

Abstract INTRODUCTION: Hymenoptera injuries are commonly caused by stinging insects. In Amazonas state, Brazil, there is no information regarding distribution, profile, and systemic manifestations associated with Hymenoptera injuries. METHODS: This study aimed to identify risk factors for systemic manifestation using the Brazilian Notifiable Diseases Surveillance System (2007 to 2015). RESULTS: Half of Hymenoptera injuries were caused by bee stings. Hymenoptera injuries were concentrated in Manaus, and 13.36% of cases displayed systemic signs. Delayed medical assistance (4 to 12 hours) presented four times more risk for systemic manifestations. CONCLUSIONS: Simple clinical observations and history of injury are critical information for prognostic improvement.

ABSTRACT

Patients with chronic lymphocytic leukemia (CLL) rarely exhibit an exaggerated insect bite-like reaction without a history of an arthropod bite. We report a case of an insect bite-like reaction in a 74-year old man with CLL. The patient presented with a 2-year history of recurrent itchy erythematous patches and blisters on the whole body. He had been diagnosed with CLL 2 years ago, and the skin lesions developed 1 month after remission. The result of a skin biopsy was consistent with insect bite. Immunohistochemical staining of the infiltrated cells showed positive reactions for CD3, CD5 and negative for CD20, CD23. Direct and indirect immunofluorescence revealed negative results. The patient was treated with oral prednisolone and dapsone, under the diagnosis of CLL-associated insect bite-like reaction, and showed marked improvement. Dermatologist should be aware of insect bite-like reaction associated with CLL as a distinct disease entity that is similar to insect bite or bullous pemphigoid.

ABSTRACT

A dermatite alérgica à picada de ectoparasitos é uma enfermidade alergoparasitária bastante comum entre animais domésticos, sendo relatada principalmente em pequenos ruminantes e em animais de companhia. Contudo, a doença é pouco diagnosticada na clínica de equídeos devido a similaridades nosológicas com outras dermatopatias. Objetivou-se, com este relato de caso, descrever a síndrome clínica, o plano diagnóstico e a conduta terapêutica de um muar acometido por essa enfermidade. Atendeu-se, no Hospital Veterinário da Universidade Federal Rural do Pernambuco, uma mula de oito anos de idade, que apresentava lesões cutâneas pápulo-crostosas e pruriginosas com evolução clínica de dois anos. Em três situações anteriores, a doença havia sido tratada como dermatite fúngica por outros médicos veterinários. Para o diagnóstico, foram solicitados exame citopatológico e parasitológico de pele, cultivo bacteriológico e fúngico, análise histopatológica e hemograma. Os exames demonstraram uma dermatite superficial perivascular eosinofílica crônica, sendo indicada a terapia tópica com dimetilsufóxido, sulfadiazina, ureia e vitamina A. O protocolo terapêutico mostrou-se satisfatório, permitindo completa remissão do quadro clínico. Este trabalho relatou achados clínicos e patológicos da dermatite alérgica à picada de Culicoides spp. em muar, além de alertar sobre a importância de exames complementares para a realização do diagnóstico diferencial e para o direcionamento terapêutico adequado.(AU)


Allergic dermatitis to ectoparasite bites is a common parasitic disease among domestic animals, being reported mainly in small ruminants and companion animals. However, the disease is poorly diagnosed in equine clinics due to nosological similarities with other skin diseases. The aim of this case report was to describe the clinical syndrome, the diagnostic plan and the therapeutic management of a mule affected by this disease. An 8-year-old mule was observed at Universidade Federal Rural de Pernambuco, presenting papular-crusted and pruritic cutaneous lesions with clinical evolution of two years. In three previous situations, the disease had been treated as fungal dermatitis by other veterinarians. For the diagnosis, cytopathological and parasitological examination of the skin, bacteriological and fungal culture, histopathological analysis and blood count were performed. The exams showed a chronic eosinophilic perivascular superficial dermatitis. A topical therapy with dimethyl sulfoxide, sulfadiazine, urea, and vitamin A was indicated. The therapeutic protocol was satisfactory, allowing complete remission of the clinical condition. This work reported clinical and pathological findings of allergic dermatitis to the bites of Culicoides spp. in muar, in addition to alerting about the importance of complementary examinations for the accomplishment of the differential diagnosis and adequate therapeutic orientation.(AU)

ABSTRACT

El estado de Yucatán (México) es un área endémica para dengue. Durante el 2015 hubo un incremento en el número de casos esperados. OBJETIVO: Describir y analizar la presentación clínica, evolución y manejo de un caso de infección por dengue con manifestaciones clínicas inespecíficas en un lactante menor, que derivaron en síndrome de choque por dengue. CASO CLÍNICO: Lactante de un mes que consulta por eritema generalizado y antecedente de picadura de insecto. Su manejo hospitalario se basó en la resolución del episodio agudo de anafilaxia. Durante su estadía presentó hipotensión, taquicardia, anemia y dificultad respiratoria. Se derivó a terapia intensiva pediátrica, pero al quinto día de estancia falleció debido a síndrome de choque. La RPC y serología de anticuerpos IgG confirmaron etiología por dengue. CONCLUSIONES: Las infecciones por dengue en el lactante menor pueden cursar afebriles, por lo cual es importante sospecharlas oportunamente ante la presencia de eritema generalizado, taquicardia e hipotensión, con la finalidad de evitar las consecuencias letales del choque por dengue.


The state of Yucatan, in Mexico, is an endemic area for dengue. During 2015, there was an unpredicted increase in the number of expected cases of dengue fever. OBJECTIVE: To describe and analyse the clinical presentation, progress, and management of a case of dengue infection with non-specific clinical manifestations in an infant which resulted in a dengue shock syndrome. CASE REPORT: One month old infant admitted to hospital with a generalised rash and a history of being bitten by an insect. He was diagnosed with anaphylaxis based on clinical manifestations and anamnesis. While in hospital, he developed hypotension, tachycardia, anaemia, and respiratory distress. He was transferred to the intensive care unit, but died on the fifth day. He tested positive to dengue virus in the PCR test and for IgG antibodies using Elisa. The basic cause of death was dengue shock syndrome. CONCLUSIONS: Dengue fever in young infant infections may be afebrile, so it is important to suspect them appropriately in the presence of a generalised rash, tachycardia, and hypotension, in order to avoid the deadly consequences of dengue shock.
