Preparation of a potent anti-scorpion-venom-serum against the venom of red scorpion (Buthus tamalus). (1/33)
A number of children and adults, especially pregnant women succumb to the sting by red Scorpion (Buthus tamalus) in Konkan region--particularly on the coastal line. No specific antiserum or any other antidote is available to treat a victim of scorpion bite and hence the need to prepare a potent antiserum. Red Scorpion (B. tamalus) venom is a mixture of a number of protein moieties and neurotoxins of low molecular weight. Therefore, the venom is poor in antigenic composition and it is difficult to get antibodies specific to neutralise lethal factor/factors. Using Bentonite as an adjuvant and extending the period of immunization a potent antiserum has been prepared capable of neutralising the lethal factor/factors. In vivo testing carried out in albino mice, guinea pigs, dogs and langurs confirms this finding and shows that the antiserum is quite effective in neutralising the scorpion venom to save the life of envenomated animals.

A clinical and biologic study was conducted in Morocco to assess the efficiency of antivenom therapy for treating victims of scorpion stings. Epidemiologic and clinical data were collected from 275 patients envenomed by Androctonus mauretanicus mauretanicus and Buthus occitanus scorpions. Patients received antivenom or other drugs. Blood samples were collected at the time of hospital admission and 1 hr and 3 hr after treatment. Serum venom levels were quantified by using an ELISA. An association was found between clinical signs of envenoming and the level of venom in serum. Patients classified as grade II (moderate envenoming) had higher serum levels of venom level than patients classified as grade I (mild envenoming). At admission to the hospital, the mean venom concentration was not significantly different between the group not treated with antivenom, the group who received 2-5 ml of antivenom, and the group who received 10 ml of antivenom. A significant decrease in serum venom levels and an improvement in the clinical conditions were observed in patients administered 10 ml of antivenom. The lower decrease in serum venom levels in patients who received 2-5 ml of antivenom was due to lower doses of antivenom. No difference in the venom concentration was observed in patients who were not treated with antivenom. The absence of administration of antivenom increased the risk of developing clinical signs at the end of the hospitalization period. However, this risk was much higher when more than 1 hr elapsed between the time of the scorpion sting and the time of hospital admission. The results demonstrate that antivenom is effective in decreasing circulating venom and morbidity. Serotherapy is more efficient when given as soon as possible after envenomation and with adequate quantities of antivenom. (+info)Medicinal and ethnoveterinary remedies of hunters in Trinidad. (3/33)
BACKGROUND: Ethnomedicines are used by hunters for themselves and their hunting dogs in Trinidad. Plants are used for snakebites, scorpion stings, for injuries and mange of dogs and to facilitate hunting success. RESULTS: Plants used include Piper hispidum, Pithecelobium unguis-cati, Bauhinia excisa, Bauhinia cumanensis, Cecropia peltata, Aframomum melegueta, Aristolochia rugosa, Aristolochia trilobata, Jatropha curcas, Jatropha gossypifolia, Nicotiana tabacum, Vernonia scorpioides, Petiveria alliacea, Renealmia alpinia, Justicia secunda, Phyllanthus urinaria,Phyllanthus niruri,Momordica charantia, Xiphidium caeruleum, Ottonia ovata, Lepianthes peltata, Capsicum frutescens, Costus scaber, Dendropanax arboreus, Siparuma guianensis, Syngonium podophyllum, Monstera dubia, Solanum species, Eclipta prostrata, Spiranthes acaulis, Croton gossypifolius, Barleria lupulina, Cola nitida, Acrocomia ierensis (tentative ID). CONCLUSION: Plant use is based on odour, and plant morphological characteristics and is embedded in a complex cultural context based on indigenous Amerindian beliefs. It is suggested that the medicinal plants exerted a physiological action on the hunter or his dog. Some of the plants mentioned contain chemicals that may explain the ethnomedicinal and ethnoveterinary use. For instance some of the plants influence the immune system or are effective against internal and external parasites. Plant baths may contribute to the health and well being of the hunting dogs.

Multiple cerebral infarcts, bilateral optic neuropathy with limb ischemia, following scorpion bite is documented. Vasospasm and autonomic storm due to envenomation is a plausible explanation for this symptom complex. (+info)Clinical profile of severe scorpion envenomation in children at rural setting. (5/33)
he present study is an attempt to evaluate the clinical manifestations of severe scorpion sting in children and their management at a rural setting. Twelve patients with severe scorpion sting referred from primary health center are presented in this report. Eight children had pulmonary edema and hypotension; two had pulmonary edema and hypertension while one each presented with hypertension and tachycardia in isolation. Oral prazosin, dobutamine infusion and sodium nitroprusside drip (SNP) were used as therapeutic options based on the symptomatology. Two children died of massive pulmonary edema despite use of SNP and dopamine drip. Anti scorpion venom did not prevent the cardiovascular manifestations of severe scorpion sting. Early administration of prazosin alleviated the severity of scorpion envenomation (+info)Management of the cardiovascular manifestations of poisoning by the Indian red scorpion (Mesobuthus tamulus). (6/33)
OBJECTIVE: The efficacy of nifedipine and prazosin in combination or alone in the management of cardiovascular manifestations caused to Mesobuthus tamulus poisoning was investigated. DESIGN: Observation and study. SETTING: Hospital at Mahad, Maharashtra, India. SUBJECTS: 62 patients who had been stung by a red scorpion were admitted from January to December 1990: 18 with hypertension, 15 with supraventricular tachycardia, 11 with pulmonary oedema, and 18 with local pain at the site of sting but no systemic involvement. Two patients with massive life-threatening pulmonary oedema were given intravenous sodium nitroprusside. RESULTS: The combination of nifedipine and prazosin was more successful in preventing myocardial damage in 16 patients with hypertension than was nifedipine alone in two other patients with hypertension. Prazosin alone helped to alleviate the cardiovascular manifestations in eight patients with pulmonary oedema and 15 with supraventricular tachycardia. One patient with pulmonary oedema died and two recovered after they were given intravenous sodium nitroprusside. CONCLUSION: Nifedipine alone did not prevent myocardial damage unless the peripheral action of venom was blocked by prazosin. (+info)Best evidence topic report.

(+info)Scorpion stings are defined as injuries caused by the venomous sting of a scorpion. These creatures have a venomous stinger on their tail, which they use to inject venom into their prey or attackers. The severity of a scorpion sting can vary greatly depending on the species of scorpion and the amount of venom injected. Some stings may cause only minor pain and swelling, while others can be life-threatening, causing symptoms such as difficulty breathing, muscle twitching, convulsions, and cardiac arrest. Immediate medical attention is required for severe scorpion stings, and treatment typically involves the use of antivenom to neutralize the venom.
I believe there may be some confusion in your question as "scorpions" are not a medical term, but instead refer to a type of arachnid. If you're asking about a medical condition that might involve scorpions, then perhaps you're referring to "scorpion stings."
Scorpion stings occur when a scorpion uses its venomous stinger to inject venom into another animal or human. The effects of a scorpion sting can vary greatly depending on the species of scorpion and the amount of venom injected, but generally, they can cause localized pain, swelling, and redness at the site of the sting. In more severe cases, symptoms such as numbness, difficulty breathing, muscle twitching, or convulsions may occur. Some species of scorpions have venom that can be life-threatening to humans, especially in children, the elderly, and those with compromised immune systems.
If you are looking for information on a specific medical condition or term, please provide more details so I can give you a more accurate answer.
Scorpion venoms are complex mixtures of neurotoxins, enzymes, and other bioactive molecules that are produced by the venom glands of scorpions. These venoms are primarily used for prey immobilization and defense. The neurotoxins found in scorpion venoms can cause a variety of symptoms in humans, including pain, swelling, numbness, and in severe cases, respiratory failure and death.
Scorpion venoms are being studied for their potential medical applications, such as in the development of new pain medications and insecticides. Additionally, some components of scorpion venom have been found to have antimicrobial properties and may be useful in the development of new antibiotics.
"Bites and stings" is a general term used to describe injuries resulting from the teeth or venomous secretions of animals. These can include:
1. Insect bites: The bite marks are usually small, punctate, and may be accompanied by symptoms such as redness, swelling, itching, and pain. Examples include mosquito, flea, bedbug, and tick bites.
2. Spider bites: Some spiders possess venomous fangs that can cause localized pain, redness, and swelling. In severe cases, systemic symptoms like muscle cramps, nausea, vomiting, and difficulty breathing may occur. The black widow and brown recluse spiders are notorious for their venomous bites.
3. Snake bites: Venomous snakes deliver toxic saliva through their fangs, which can lead to local tissue damage, swelling, pain, and potentially life-threatening systemic effects such as paralysis, bleeding disorders, and respiratory failure.
4. Mammal bites: Animal bites from mammals like dogs, cats, and wild animals can cause puncture wounds, lacerations, and crush injuries. They may also transmit infectious diseases, such as rabies.
5. Marine animal stings: Stings from jellyfish, sea urchins, stingrays, and other marine creatures can result in localized pain, redness, swelling, and systemic symptoms like difficulty breathing, muscle cramps, and altered heart rhythms. Some marine animals' venoms can cause severe allergic reactions or even death.
Treatment for bites and stings varies depending on the type and severity of the injury. It may include wound care, pain management, antibiotics to prevent infection, and in some cases, antivenom therapy to counteract the effects of venom. Seeking immediate medical attention is crucial in severe cases or when systemic symptoms are present.
Antivenins, also known as antivenoms, are medications created specifically to counteract venomous bites or stings from various creatures such as snakes, spiders, scorpions, and marine animals. They contain antibodies that bind to and neutralize the toxic proteins present in venom. Antivenins are usually made by immunizing large animals (like horses) with small amounts of venom over time, which prompts the animal's immune system to produce antibodies against the venom. The antibody-rich serum is then collected from the immunized animal and purified for use as an antivenin.
When administered to a victim who has been envenomated, antivenins work by binding to the venom molecules, preventing them from causing further damage to the body's tissues and organs. This helps minimize the severity of symptoms and can save lives in life-threatening situations. It is essential to seek immediate medical attention if bitten or stung by a venomous creature, as antivenins should be administered as soon as possible for optimal effectiveness.
Insect bites and stings refer to the penetration of the skin by insects, such as mosquitoes, fleas, ticks, or bees, often resulting in localized symptoms including redness, swelling, itching, and pain. The reaction can vary depending on the individual's sensitivity and the type of insect. In some cases, systemic reactions like anaphylaxis may occur, which requires immediate medical attention. Treatment typically involves relieving symptoms with topical creams, antihistamines, or in severe cases, epinephrine. Prevention measures include using insect repellent and protective clothing.
Pulmonary edema is a medical condition characterized by the accumulation of fluid in the alveoli (air sacs) and interstitial spaces (the area surrounding the alveoli) within the lungs. This buildup of fluid can lead to impaired gas exchange, resulting in shortness of breath, coughing, and difficulty breathing, especially when lying down. Pulmonary edema is often a complication of heart failure, but it can also be caused by other conditions such as pneumonia, trauma, or exposure to certain toxins.
In the early stages of pulmonary edema, patients may experience mild symptoms such as shortness of breath during physical activity. However, as the condition progresses, symptoms can become more severe and include:
* Severe shortness of breath, even at rest
* Wheezing or coughing up pink, frothy sputum
* Rapid breathing and heart rate
* Anxiety or restlessness
* Bluish discoloration of the skin (cyanosis) due to lack of oxygen
Pulmonary edema can be diagnosed through a combination of physical examination, medical history, chest X-ray, and other diagnostic tests such as echocardiography or CT scan. Treatment typically involves addressing the underlying cause of the condition, as well as providing supportive care such as supplemental oxygen, diuretics to help remove excess fluid from the body, and medications to help reduce anxiety and improve breathing. In severe cases, mechanical ventilation may be necessary to support respiratory function.
