Hymenoptera venom allergy in children.

From a taxonomic point of view, Hymenoptera are subclassified into families: Apidae, including honeybees (Apis mellifera) and bumblebees (Bombus), and Vespidae, which, in turn, are divided into the subfamilies of Vespinae (wasps, including hornets, vespules, dolichovespules) and Polistinae (paper wasp). Hypersensitivity to Hymenoptera venom can be linked to immunological (IgE-mediated or non-IgE-mediated) and non-immunological mechanisms. Reactions are classified into local reactions, large local reactions, systemic reactions, toxic reactions, and unusual reactions.

Clinical Profile and Outcomes of Pediatric Snakebite Envenomation: A Three-Year Retrospective Study From a Rural Tertiary Care Center in South India.

Background Snakebite envenomation remains a significant public health challenge in tropical countries, particularly affecting the pediatric population. Children are especially vulnerable because of their smaller body mass, outdoor activities, and delayed presentation to healthcare facilities. This study aimed to analyze the clinical profile, demographic patterns, and envenomation characteristics of snakebites in children aged 1-16 years presenting to a tertiary care center.

Epidemiological patterns and trends of paediatric snakebites in Sri Lanka.

Objectives: This study aimed to analyse the epidemiological patterns of paediatric snake bites in Sri Lanka over a 4-year period (2020-2024).

Methods: A multi-centre, retrospective observational study was conducted from June 2020 to June 2024 across nine governmental hospitals in seven provinces of Sri Lanka. Data were collected based on 757 children presenting with snake bites.

Willingness to pay for a mosquito bite prevention 'forest pack' in Cambodia: results of a discrete choice experiment.

Background: Progress towards malaria elimination in the Greater Mekong Subregion has left much of the residual malaria transmission concentrated among forest-exposed populations for whom traditional domicile focused malaria vector control is unlikely to be effective. New tools to protect these populations from vector biting outdoors are needed.

Methods: Alongside implementation research on the deployment of a "forest pack" consisting of a volatile pyrethroid (transfluthrin)-based spatial repellent (VPSR), a picaridin-based topical repellent and etofenprox treatment of clothing, an assessment was made of participant willingness to pay for the forest packs and variants of the packs using a discrete choice experiment.

Impact of nighttime human behavior on exposure to malaria vectors and effectiveness of using long-lasting insecticidal nets in the Ethiopian lowlands and highlands.

Background: Ethiopia continues to grapple with a persistent malaria burden, characterized by ongoing transmission and recurrent outbreaks. Human behavior influences both malaria exposure and the effectiveness of vector interventions, complicating malaria control efforts. Implementing tailored strategies that account for the complex interplay between human activities and vector behavior remains a challenge in both high- and low-transmission areas in Ethiopia, particularly for vulnerable highland populations and temporary labor migrants, due to lack of data.

The effect of novel mosquito bite prevention tools on Anopheles minimus landing and key secondary endpoints: semi-field evaluations in Thailand.

Background: The Greater Mekong Subregion (GMS) aims to eliminate all human malaria by 2030 and is making substantial progress toward this goal, with malaria increasingly confined to forest foci. These transmission foci are predominantly inhabited by ethnic minorities, local populations, and rural mobile and migrant populations working in mining and agriculture. The recommendations of the World Health Organization (WHO) on malaria elimination states that small population groups which constitute a large proportion of the malaria transmission reservoir should benefit from targeted strategies to reduce transmission overall.

The AxBioTick study - immune gene expression signatures in human skin bitten by Borrelia-infected versus non-infected ticks.

Background: Borrelia infection is caused by Borrelia burgdorferi sensu lato and transmitted by Ixodes ricinus ticks, a common tick-borne infection in Northern Europe. The establishment of Borrelia infection depends on transmission of the spirochetes, as well as the immune response generated in the skin after a bite. Here we aim to investigate the local immune response in the skin after a tick bite and assess the possible direct effects of Borrelia, by applying gene expression analysis of the immune response in skin exposed to Borrelia-infected and non-infected ticks, respectively.

Ticked Off: A Case of Disappearing Cell Lines.

Human granulocytic anaplasmosis (HGA) is transmitted by the black-legged tick and presents with fever, thrombocytopenia, leukocytopenia, and elevated transaminases. If left untreated, HGA can progress to hemophagocytic lymphohistiocytosis (HLH), which can be fatal. Here, we discuss a case of a woman diagnosed with anaplasmosis who was treated promptly.

Have you heard of Rift Valley fever? Findings from a multi-country study in East and Central Africa.

Introduction: Rift Valley Fever (RVF) has caused outbreaks in Africa, impacting human health and animal trade. Recently, sporadic detections among humans and animals in East Africa have replaced large-scale outbreaks. We assessed RVF knowledge levels in East and Central Africa across countries with different epidemiological profiles.

Flexor Tendon Rupture After a Cat Bite - A Case Report of An Uncommon Sequela.

Introduction: Cat bites are a remarkably common injury seen in the emergency department setting . Due to the morphology of feline teeth and anatomy of the human hand, seemingly innocuous surface bites can seed infections in deeper structures of the hand that can result in adverse outcomes. We report on a case of a rare complication of a flexor tendon rupture that occurred well after the initial treatment of a superficial infection.

Metatranscriptomic analysis reveals the diversity of RNA viruses in ticks in Inner Mongolia, China.

Background: Ticks are widely distributed throughout China and are the second most prevalent pathogen vectors in the world, following only mosquitoes. Tick bites can lead to Lyme disease, forest encephalitis, and other illnesses that may result in death under severe circumstances. Materials and methods: Ticks collected from March 2021 to May 2023 were pooled and used in metatranscriptomic analyses to gain insight into the diversity and distribution of tick-borne viruses in Inner Mongolia.

Combatting rabies outbreaks in Vietnam: High time to enforce restrictions on dog meat farming, a key source of transmission.

In Vietnam, farming dogs for meat is not illegal but is increasingly marginalized as dog meat consumption comes under heightened social scrutiny. This loosely regulated practice likely increases the risk of rabies transmission to humans. At a time when human-wildlife conflict has become a major discussion point for global health, stray dogs escaping or being deliberately released from dog farms is a cause for serious concern.

Az antibiotikum-rezisztencia a modern orvoslás egyre több kihívást adó problémája. A kutyaharapás gyógyításának számos esetben elengedhetetlen része az antibiotikus kezelés. Az eredményes gyógyításhoz minél hamarabb ismerni kellene a kórokozókat és azok antibiotikum-érzékenységét.

Characterization of human exposure to Anopheles and Aedes bites using antibody-based biomarkers in rural zone of Cameroon.

Malaria and Aedes-borne diseases remain major causes of mortality, morbidity, and disability in most developing countries. Surveillance of transmission patterns associated with vector control remains strategic for combating these diseases. Due to the limitions of current surveillance tools used to assess human exposure to mosquito bites, human antibody (Ab) responses to salivary peptides from Anopheles (gSG6-P1) and Aedes (Nterm-34kDa) are increasingly being used to measure direct human-Anopheles or Aedes contact.

Persistent human babesiosis with low-grade parasitemia, challenges for clinical diagnosis and management.

Human babesiosis, caused by several parasites and transmitted by tick bites and other blood-associated containments, has emerged as a major public health threat around the world. In the absence of readily discernible clinical manifestations, the diagnosis of human babesiosis has been contingent upon the identification of parasites through the utilization of detection arrays. Nevertheless, cases of persistent and relapsing babesiosis with low-grade parasitemia have been sporadically observed in patients with and without immunosuppression, prompting a challenge to the reliability of routine clinical laboratory tests and efficient anti-babesial therapy.

Reconstruction of the Amputated Auricle with Retro Auricular Flap in the Three Acts After a Human Bite.

Amputations of the earlobe after a human bite are rare. But when they appear, they present a challenge for the plastic surgeon, due to its reconstruction since the earlobe is anatomically built only from skin and cartilage. In these cases, the retro auricular flap represents a perfect solution for reconstruction.

Dogs as Reservoirs for Leishmania donovani, Bihar, India, 2018-2022.

Visceral leishmaniasis derived from Leishmania donovani is transmitted by sand flies (Phlebotomus argentipes) throughout the Indian subcontinent. Although considered anthroponotic, L. donovani infects other mammals susceptible to sand fly bites, including dogs.
