Effective methods for tick removal: A systematic review

Assessment of cattle tick infestation: Molecular insights into Rhipicephalus annulatus and the efficacy of garlic oil and nanoemulsion as acaricidal agents

Ticks, particularly Rhipicephalus annulatus, pose significant threats to livestock, causing economic losses and transmitting various infectious diseases. This study aimed to evaluate the potential acaricidal properties of garlic oil and its nanoemulsion against ticks infesting cattle, Rhipicephalus annulatus through the evaluation of mortality rate and morphological changes of the treated ticks. The study also included prevalence, risk factors, and molecular confirmation of tick species. Genetic characterization confirmed the identity of R. annulatus. Our results revealed a high prevalence of R. annulatus (46.9%) with a higher risk in male cattle (50%) than females (44.9%) and a nonsignificant high infection (49.1%) in animals ≤ 1 year old. The acaricidal efficiency of garlic oil and its nanoemulsion was concentration and time-dependent. The high concentration of garlic oil (20 mg/L) induced complete mortality within 48 hours. The nanoemulsion formulation enhanced efficacy, particularly at 5 mg/L, which exhibited rapid and substantial acaricidal activity. Scanning electron microscopy revealed morphological alterations induced by garlic oil and its nanoemulsion, including changes to the anterior capitulum, dorsal, and ventral cuticles. The study contributes to the exploration of effective, safe, and eco-friendly alternatives for tick control. Further research is warranted to validate their efficacy under diverse conditions and assess practical strategies.

2021 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations: Summary From the Basic Life Support; Advanced Life Support; Neonatal Life Support; Education, Implementation, and Teams; First Aid Task Forces; and the COVID-19 Working Group

The International Liaison Committee on Resuscitation initiated a continuous review of new, peer-reviewed published cardiopulmonary resuscitation science. This is the fifth annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations; a more comprehensive review was done in 2020. This latest summary addresses the most recently published resuscitation evidence reviewed by International Liaison Committee on Resuscitation task force science experts. Topics covered by systematic reviews in this summary include resuscitation topics of video-based dispatch systems; head-up cardiopulmonary resuscitation; early coronary angiography after return of spontaneous circulation; cardiopulmonary resuscitation in the prone patient; cord management at birth for preterm and term infants; devices for administering positive-pressure ventilation at birth; family presence during neonatal resuscitation; self-directed, digitally based basic life support education and training in adults and children; coronavirus disease 2019 infection risk to rescuers from patients in cardiac arrest; and first aid topics, including cooling with water for thermal burns, oral rehydration for exertional dehydration, pediatric tourniquet use, and methods of tick removal. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, according to the Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations or good practice statements. Insights into the deliberations of the task forces are provided in Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces listed priority knowledge gaps for further research.

Lyme Neuroborreliosis in Children

Lyme neuroborreliosis (LNB) is an infectious disease, developing after a tick bite and the dissemination of Borrelia burgdorferi sensu lato spirochetes reach the nervous system. The infection occurs in children and adults but with different clinical courses. Adults complain of radicular pain and paresis, while among the pediatric population, the most common manifestations of LNB are facial nerve palsy and/or subacute meningitis. Moreover, atypical symptoms, such as fatigue, loss of appetite, or mood changes, may also occur. The awareness of the various clinical features existence presented by children with LNB suspicion remains to be of the greatest importance to diagnose and manage the disease.

Lyme disease in Western Europe: an emerging problem? A systematic review

Objectives: Lyme borreliosis is the most common zoonotic disease in Europe and causes an estimated total burden of 10.55 disability-adjusted life years (DALY) per 100 000 population. Its incidence in Western Europe is assumed to be increasing, yet this remains to be confirmed. The aim of this study was to assess the emergence of Lyme disease in Western Europe by performing a systematic review of the scientific literature.Methods: Pubmed, Embase and grey literature were searched from database inception until August 2018 for articles reporting the incidence of Lyme borreliosis in Western European countries. We included observational studies in English that reported data on a random sample of the population and fulfilled our definition of Lyme disease diagnosis. Annual population-weighted averages and the evolution of Lyme borreliosis incidence were extracted or calculated for every Western European country.Results: Our review identified 1514 and included 18 studies next to seven surveillance reports reporting data from 16 Western European countries. Incidence of Lyme borreliosis ranged from 0.001 (Italy) to 632 (Sweden, Blekinge county) cases/100 000/year. Iceland reported the strongest emergence with an average yearly increase of 21.15% over a 12-year period, whereas Italy reported the strongest average yearly decrease of 52.71% over a 5-year period. Very limited high-quality data were available on Lyme borreliosis incidence in the southern Western European countries.Conclusion: Diagnosis of Lyme borreliosis is on the rise in some Western European countries, mostly in the northern and central part. Better surveillance in the southern countries is necessary.

Tick bites in Japan

Ticks are blood-sucking ectoparasites belonging to the order Acarina, class Arachnida. In Japan, eight genera and 46 species are known. Tick bite patients frequently present to dermatology clinics. The main causative species of human tick bites are Ixodes persulcatus and Ixodes ovatus in northern to central Japan, and Amblyomma testudinarium and Haemaphysalis longicornis in western Japan. Tick bites often occur from April to September, particularly in May through July, consistent with the active period for ticks. Although erythema usually does not develop at the tick bite site, a small area of erythema may be seen in some cases. Occasionally, an erythema larger than 50 mm in diameter are formed at the bite site, known as tick-associated rash illness. It is thought that the erythema is a delayed-type allergic reaction to the substances in tick saliva. Repeated tick bites induce immunoglobulin E production against galactose-1,3-α-galactose, one of the substances in tick saliva, which may trigger an immediate allergic reaction. The most reliable method to remove a tick sucking blood is en bloc resection of the tick and surrounding skin under local anesthesia. Insect repellent spray containing icaridin or DEET are effective to prevent ticks from attaching and tick-borne infections. It is important to educate not only dermatologists but also the general public regarding tick bites.
