Can anything be done to maintain the effectiveness of pyrethroid-impregnated bednets against malaria vectors? (1/724)

Pyrethroid-treated bednets are the most promising available method of controlling malaria in the tropical world. Every effort should be made to find methods of responding to, or preventing, the emergence of pyrethroid resistance in the Anopheles vectors. Some cases of such resistance are known, notably in An. gambiae in West Africa where the kdr type of resistance has been selected, probably because of the use of pyrethroids on cotton. Because pyrethroids are irritant to mosquitoes, laboratory studies on the impact of, and selection for, resistance need to be conducted with free-flying mosquitoes in conditions that are as realistic as possible. Such studies are beginning to suggest that, although there is cross-resistance to all pyrethroids, some treatments are less likely to select for resistance than others are. Organophosphate, carbamate and phenyl pyrazole insecticides have been tested as alternative treatments for nets or curtains. Attempts have been made to mix an insect growth regulator and a pyrethroid on netting to sterilize pyrethroid-resistant mosquitoes that are not killed after contact with the netting. There seems to be no easy solution to the problem of pyrethroid resistance management, but further research is urgently needed.  (+info)

Altered properties of neuronal sodium channels associated with genetic resistance to pyrethroids. (2/724)

Genetic resistance to pyrethroid insecticides involves nervous system insensitivity linked to regulatory and structural genes of voltage-sensitive sodium channels. We examined the properties and relative density of sodium channels in central neurons of susceptible and pyrethroid-resistant (Pyr-R) insects that were homozygous for the amino acid substitution V421M in the I-S6 transmembrane segment. Pyr-R sodium channels show approximately 21-fold lower sensitivity to the synthetic pyrethroid permethrin and a approximately 2-fold increased sensitivity to the alpha-scorpion toxin LqhalphaIT. Pyr-R channels also exhibit altered gating properties, including a approximately 13 mV positive shift in voltage-dependent activation and approximately 7 mV positive shift in steady-state inactivation. Consistent with these changes in gating behavior, Pyr-R central neurons are less excitable, as evidenced by an approximately 11 mV elevation of action potential threshold. No differences in sodium channel density are evident. The altered properties of Pyr-R sodium channels provide a plausible molecular basis for nervous system insensitivity associated with pyrethroid resistance.  (+info)

Estrogenic potential of certain pyrethroid compounds in the MCF-7 human breast carcinoma cell line. (3/724)

Estrogens, whether natural or synthetic, clearly influence reproductive development, senescence, and carcinogenesis. Pyrethroid insecticides are now the most widely used agents for indoor pest control, providing potential for human exposure. Using the MCF-7 human breast carcinoma cell line, we studied the estrogenic potential of several synthetic pyrethroid compounds in vitro using pS2 mRNA levels as the end point. We tested sumithrin, fenvalerate, d-trans allethrin, and permethrin. Nanomolar concentrations of either sumithrin or fenvalerate were sufficient to increase pS2 expression slightly above basal levels. At micromolar concentrations, these two pyrethroid compounds induced pS2 expression to levels comparable to those elicited by 10 nM 17ss-estradiol (fivefold). The estrogenic activity of sumithrin was abolished with co-treatment with an antiestrogen (ICI 164,384), whereas estrogenic activity of fenvalerate was not significantly diminished with antiestrogen co-treatment. In addition, both sumithrin and fenvalerate were able to induce cell proliferation of MCF-7 cells in a dose-response fashion. Neither permethrin nor d-trans allethrin affected pS2 expression. Permethrin had a noticeable effect on cell proliferation at 100 microM, whereas d-trans allethrin slightly induced MCF-7 cell proliferation at 10 microM, but was toxic at higher concentrations. Overall, our studies imply that each pyrethroid compound is unique in its ability to influence several cellular pathways. These findings suggest that pyrethroids should be considered to be hormone disruptors, and their potential to affect endocrine function in humans and wildlife should be investigated.  (+info)

The impact of charging for insecticide on the Gambian National Impregnated Bednet Programme. (4/724)

During the second year of the Gambian National Impregnated Bednet Programme (NIBP) charges for insecticide ($0.50 per net) were introduced into the half of the primary health care villages in the country where insecticide have been provided free of charge the previous year. Free insecticide was provided in the remaining villages that had acted as controls during the previous year. In villages where insecticide was provided free, 77% of nets were treated with insecticide. In contrast, in villages where charges were made coverage was only 14%. During the first year of the NIBP, mortality in children was significantly lower in villages where insecticide was provided free than in the control villages. Introduction of a charge for insecticide into the first group of villages and the provision of free insecticide in the latter abolished this difference. The cash income of rural Gambians is very limited and payment of even $2-3 for insecticide treatment for all the bednets in a household represents a substantial outlay. Further education on the benefits of treatment of nets and/or the provision of cheaper insecticide will be required before the full benefits of this powerful new malaria control measure can be fully realised in the Gambia.  (+info)

Yeast calcineurin regulates nuclear localization of the Crz1p transcription factor through dephosphorylation. (5/724)

Calcineurin, a Ca2+/calmodulin dependent protein phosphatase, regulates Ca2+-dependent processes in a wide variety of cells. In the yeast, Saccharomyces cerevisiae, calcineurin effects Ca2+-dependent changes in gene expression through regulation of the Crz1p transcription factor. We show here that calcineurin dephosphorylates Crz1p and that this results in translocation of Crz1p to the nucleus. We identify a region of Crz1p that is required for calcineurin-dependent regulation of its phosphorylation, localization, and activity, and show that this region has significant sequence simlarity to a portion of NF-AT, a family of mammalian transcription factors whose localization is also regulated by calcineurin. Thus, the mechanism of Ca2+/calcineurin-dependent signaling shows remarkable conservation between yeast and mammalian cells.  (+info)

Control of malaria vectors: cost analysis in a province of northern Vietnam. (6/724)

The cost of permethrin-treated bednets (50% EC; 0.2 g/m2, 2 rounds per year) was compared to the cost of residual spraying with lambdacyhalothrin 10% WP (0.03 g/m2, once yearly) in Hoa Binh, a mountainous province in northern Vietnam. Calculations of the amounts of insecticides needed were based on national guidelines, on data from a cross-sectional survey and on district activity reports. The actual cost of insecticide required per person per year was lower for impregnation (US$ 0.26) than for spraying (US$ 0.36), but the difference was smaller than expected. The total cost for impregnated bednets per person per year amounted to US$ 0.90 compared to USS 0.47 for spraying. The determining factor was the cost of the net, amounting to US$ 0.58 per person per year, assuming a 5-year life of the net. Other material (excluding nets), labour and transport combined, accounted for only 17% of the impregnation cost and 23% of spraying expenses. However, for the National Malaria Control Programme of Vietnam, the cost per person per year for impregnated bednets amounted to US$ 0.32 only, because the vast majority of nets are bought by the population. For spraying, the programme had to bear the entire cost.  (+info)

Status of pyrethroid resistance in Anopheles gambiae sensu lato. (7/724)

The present study confirms the presence of pyrethroid resistance among Anopheles gambiae s.l mosquitos in Cote d'Ivoire and reports the observation of such resistance in two other countries in West Africa (Benin and Burkina Faso). Malaria vector populations from Cameroon (Central Africa), Senegal (West Africa) and Botswana (southern Africa) were found to be susceptible to pyrethroids. In the most resistant mosquito populations, resistance to permethrin was associated with reduced mortality, not only with respect to this compound but also towards deltamethrin. Moreover, a significant increase in knockdown time was observed in some mosquito populations before any decrease in mortality, suggesting that knockdown time could be a good indicator for the early detection of pyrethroid resistance. In view of the current extension of such resistance, there is an urgent need to set up a network in Africa to evaluate its development. It is also vital that the impact of this resistance on pyrethroid-impregnated bednets be assessed.  (+info)

A new strategy for treating nets. Part 1: formulation and dosage. (8/724)

The conventional dosages of pyrethroid insecticides on mosquito nets assume that nets will be retreated at 6-12 month intervals. However, dosage should be related to washing of nets; if nets are only washed once or twice a year, their dosage requirements will be different to those which are washed fortnightly. A 'low-dose, frequent-wash' retreatment system might be technically more appropriate and more affordable where nets are washed frequently, as they are in Dar es Salaam. Moreover, for use as a domestic insecticide, water-based formulations of pyrethroid are preferable to the more commonly used emulsifiable concentrates (ECs). This paper reports laboratory evaluations of three formulations (ECs, Flowable, CS) of three pyrethroids (deltamethrin, lambdacyhalothrin, permethrin). Insecticidal activity was tested using serial bioassays at a range of dosages using Anopheles gambiae. The water-based formulations were no less effective than the ECs, even at the lowest dosages. Nets treated with 3 mg/m2 and then repeatedly washed and retreated after each wash with either 3 mg/m2 or 1 mg/m2 were subjected to gas chromatography analysis. This showed that the amounts of pyrethroid in the nets accumulated rapidly over the first few wash-retreatment cycles and then remained fairly stable over subsequent cycles. These nets gave consistently high bioassay mortalities throughout the experiment, while the mortality declined rapidly after several washes with the nets that were treated at 3 mg/m2 but not retreated. Experimental huts were used to compare the effectiveness of these 2 net retreatment regimes and nets which were not retreated. All nets caused high mortality rates amongst Anopheles females, but had negligible effects on culicines; either in killing them or in preventing feeding. Therefore use of a high 'loading' dose for initial treatment with lower 'maintenance' doses for retreatment may be preferable to ensure that net users promptly perceive the benefits of the insecticide against culicines.  (+info)

Chrysanthemum cinerariifolium is a specific species of chrysanthemum flower that is native to Asia. It is also known as the "Pyrethrum daisy" or "Dalmatian chrysanthemum." This plant is most well-known for its production of pyrethrin, a natural insecticide. The dried flowers of this species contain high concentrations of pyrethrins, which are potent neurotoxins to insects but considered low in toxicity to mammals and birds.

The medical definition of Chrysanthemum cinerariifolium is related to its use as a traditional herbal medicine in some cultures. The flowers are used to make teas and tinctures, which have been used to treat various conditions such as fever, headache, respiratory infections, and skin diseases. However, it's important to note that the scientific evidence supporting these uses is limited, and more research is needed before any definitive medical claims can be made.

It's also worth noting that Chrysanthemum cinerariifolium extracts and pyrethrins are used in some commercial insecticides and pesticides. These products are used to control a wide variety of pests, including mosquitoes, fleas, ticks, and agricultural pests. Pyrethrin-based insecticides are considered to be relatively safe for use around humans and animals, but they can be toxic to fish and other aquatic organisms, so they must be used with caution in or near bodies of water.

Pyrethrins are a group of naturally occurring organic compounds extracted from the flowers of Chrysanthemum cinerariaefolium and Chrysanthemum coccineum. They have been used for centuries as insecticides due to their ability to disrupt the nervous system of insects, leading to paralysis and death. Pyrethrins are composed of six esters, pyrethrin I and II, cinerin I and II, and jasmolin I and II, which have different insecticidal properties but share a similar mode of action. They are commonly used in household insect sprays, pet shampoos, and agricultural applications to control a wide range of pests. However, pyrethrins can be toxic to fish and some beneficial insects, so they must be used with caution.

I apologize for any confusion, but "Thysanoptera" is not a medical term. It is an order of small, thin-bodied insects, also known as thrips. Thysanoptera species are typically less than 2 mm long and have delicate fringed wings. They are commonly found in various environments such as flowers, leaves, and even soil. While they can be plant pests and occasionally transmit plant viruses, they do not have a direct relevance to human medicine.

Insect repellents are substances that are applied to the skin, clothing, or other surfaces to deter insects from landing or crawling on that surface. They work by masking the scents that attract insects or by repelling them with unpleasant odors. Insect repellents can be chemical-based, such as those containing DEET (N,N-diethyl-m-toluamide), picaridin, or IR3535, or they can be natural, such as those containing oil of lemon eucalyptus or citronella. These substances work by interfering with the insect's ability to detect human scent, making it less likely that they will come into contact with the person using the repellent. Insect repellents are an important tool in preventing insect-borne diseases such as Lyme disease, West Nile virus, and Zika virus.

Insecticides are substances or mixtures of substances intended for preventing, destroying, or mitigating any pest, including insects, arachnids, or other related pests. They can be chemical or biological agents that disrupt the growth, development, or behavior of these organisms, leading to their death or incapacitation. Insecticides are widely used in agriculture, public health, and residential settings for pest control. However, they must be used with caution due to potential risks to non-target organisms and the environment.

"Pediculus" is the medical term for a type of small, wingless parasitic insect that can be found in human hair and on the body. There are two main species that affect humans:

1. Pediculus humanus capitis - also known as the head louse, it primarily lives on the scalp and is responsible for causing head lice infestations.
2. Pediculus humanus corporis - also known as the body louse, it typically lives in clothing and on the body, particularly in seams and folds of clothing, and can cause body lice infestations.

Both species of Pediculus feed on human blood and can cause itching and skin irritation. They are primarily spread through close personal contact and sharing of items such as hats, combs, and clothing.

Piperonyl Butoxide (PBO) is not a medication or a therapeutic agent, so it doesn't have a typical "medical definition" as such. However, it is a chemical compound with a specific use in the medical field, particularly in relation to pest control and public health.

Piperonyl Butoxide is an organic compound that is commonly used as a synergist in pesticides. A synergist is a substance that enhances the effectiveness of a primary active ingredient. In the case of PBO, it is often combined with pyrethrin or pyrethroid-based insecticides to increase their potency and duration of action.

PBO works by inhibiting certain enzymes in insects that would otherwise help them metabolize and detoxify the insecticide. This allows the insecticide to remain active for a longer period, thereby increasing its efficacy.

It's important to note that while PBO is used in pest control, it is not directly toxic to humans or other mammals in the concentrations typically used. However, exposure should still be minimized as much as possible due to potential respiratory and skin irritation, and long-term health effects are not fully understood.

A lice infestation, also known as pediculosis, is a condition characterized by the presence and multiplication of parasitic insects called lice on a person's body. The three main types of lice that can infest humans are:

1. Head lice (Pediculus humanus capitis): These lice primarily live on the scalp, neck, and behind the ears, feeding on human blood. They lay their eggs (nits) on hair shafts close to the scalp. Head lice infestations are most common in children aged 3-12 years old.

2. Body lice (Pediculus humanus corporis): These lice typically live and lay eggs on clothing, particularly seams and collars, near the body's warmest areas. They move to the skin to feed on blood, usually at night. Body lice infestations are more common in people who experience homelessness or overcrowded living conditions with limited access to clean clothing and hygiene facilities.

3. Pubic lice (Pthirus pubis): Also known as crab lice, these lice primarily live in coarse body hair, such as the pubic area, armpits, eyelashes, eyebrows, beard, or mustache. They feed on human blood and lay eggs on hair shafts close to the skin. Pubic lice infestations are typically sexually transmitted but can also occur through close personal contact with an infected individual or sharing contaminated items like bedding or clothing.

Symptoms of a lice infestation may include intense itching, tickling sensations, and visible red bumps or sores on the skin caused by lice bites. In some cases, secondary bacterial infections can occur due to scratching. Diagnosis is usually made through visual identification of lice or nits on the body or clothing. Treatment typically involves topical medications, such as shampoos, creams, or lotions, and thorough cleaning of bedding, clothing, and personal items to prevent reinfestation.

Poison Control Centers are specialized organizations that provide immediate, free, and expert advice and treatment recommendations for exposure to potentially harmful substances, also known as poisons. They are staffed by trained healthcare professionals, including medical toxicologists, nurses, pharmacists, and poison information providers. These centers manage a wide range of poisoning cases, from accidental ingestions in children to intentional overdoses and chemical exposures in adults. They offer 24/7 emergency hotline services to the public, healthcare providers, and first responders for poison-related emergencies and provide valuable resources for poison prevention and education. The primary goal of Poison Control Centers is to reduce the morbidity and mortality associated with poison exposures and promote overall public health and safety.

Poisoning is defined medically as the harmful, sometimes fatal, effect produced by a substance when it is introduced into or absorbed by living tissue. This can occur through various routes such as ingestion, inhalation, injection, or absorption through the skin. The severity of poisoning depends on the type and amount of toxin involved, the route of exposure, and the individual's age, health status, and susceptibility. Symptoms can range from mild irritation to serious conditions affecting multiple organs, and may include nausea, vomiting, diarrhea, abdominal pain, difficulty breathing, seizures, or unconsciousness. Immediate medical attention is required in cases of poisoning to prevent severe health consequences or death.

Oviposition is a medical/biological term that refers to the process of laying or depositing eggs by female organisms, including birds, reptiles, insects, and fish. In humans and other mammals, the term is not applicable since they give birth to live young rather than laying eggs.

Health facilities, also known as healthcare facilities, are organizations that provide health services, treatments, and care to individuals in need of medical attention. These facilities can include various types of establishments such as hospitals, clinics, doctor's offices, dental practices, long-term care facilities, rehabilitation centers, and diagnostic imaging centers.

Health facilities are designed to offer a range of services that promote health, prevent illness, diagnose and treat medical conditions, and provide ongoing care for patients with chronic illnesses or disabilities. They may also offer educational programs and resources to help individuals maintain their health and well-being.

The specific services offered by health facilities can vary widely depending on the type and size of the facility, as well as its location and target population. However, all health facilities are required to meet certain standards for safety, quality, and patient care in order to ensure that patients receive the best possible treatment and outcomes.
