Envenenamiento de Chelydra serpentina Reptilia: Testudines por Tityus trivittatus Scorpionida: Buthidae Envenomation of Chelydra serpentina Reptilia: Testudines by Tityus trivittatus Scorpionida: Este es el primer comunicado sobre el envenenamiento de quelonios por escorpiones. We report the case of a snapping turtle Chelydra serpentina found tetanized, with the limbs in extension, mydriasis and poor response to external stimuli, in whose terrarium was found a Tityus trivittatus scorpion.

Based on the clear clinical picture of huanos, the turtle was treated with a specific scorpion antivenin, returning to a state of muscle relaxation after six hours of treatment and it was found totally normal at 24 hours, without envenoming sequelae. This is the first report on turtle envenomation by scorpion. The scorpion envenomation in reptiles and the treatment with specific antivenom is discussed.

To een the external causes of death and mortality trends due to injuries and poisoning in Mexican adolescents, from to This is a descriptive study of deaths occurring in Mexico from to Full Text Available El plomo Pb es un contaminante ambiental que causa efectos adversos a la salud humana. Paraquat is the best-selling herbicide throughout the world, It is absorbed by the digestive and inhalatory routes.

If it reaches the lungs, congestion with swelling is developed, increased alveolar macrophages that progresses to fibrosis and pulmonary edema, which occur until 14 days after bumanos if not treated timely and correct. Paraquat is directed primarily to the lungs and therefore generates free radicals oxidants, which is why, in cases of acute poisoning is absolutely forbidden to use oxygen except where arterial blood partial pressure of oxygen in is less than 50 mm Hg.

A patient who developed an adult respiratory distress syndrome ARDS secondary to deliberate ingestion of paraquat is presented. Initial patient management was performed with gastric lavage.

Paraquat is a herbicide widely used in agriculture. Envenomation by neotropical Opisthoglyphous colubrid Thamnodynastes cf. Colubridae in Venezuela Envenenamiento por la colubrida raticiads Thamnodynastes cf. The patient was bitten on the middle finger of the left hand, and shows signs of pronounced local manifestations of envenomation such as bleeding from the tooth intoxicaxion, swelling and warmth.

He was treated with local care, analgesics, and steroids. He was dismissed from the hospital and observed at home during five days with marked improvement of envenomation. The snake was brought to the medical consult and identified as a Thamnodynastes cf. This report represents the first T. El paciente fue mordido intoxucacion el dedo medio de la mano izquierda, mostrando pronunciados signos locales de sangramiento por la impronta ocasionada por los dientes de la pro, edema y calor local.

Este es el primer caso humano descrito, ocasionado por un T. O paciente foi submetido a dois ciclos de terapia imunossupressora com ciclofosfamida, metilprednisolona e intoxiaccion.

Paraquat is a nonselective contact herbicide of great opr importance, being associated with high mortality rates, mainly due to respiratory failure. We report the case of a year-old male admitted to the emergency room with a sore throat, dysphagia, hemoptysis, and retrosternal pain after the ingestion of 50 mL of a paraquat solution, four days prior to admission.

Chest CT scans revealed humsnos opacities, pneumomediastinum, pneumothorax, and subcutaneous emphysema. The patient was submitted to two cycles of immunosuppressive therapy with cyclophosphamide, methylprednisolone, and dexamethasone. The pulmonary gas exchange parameters gradually improved, and the patient was discharged four weeks later. The clinical and tomographic follow-up evaluations performed at four months after discharge showed that there had been further clinical improvement. Paraquat poisoning in the dog.

Recovery from paraquat poisoning in the dog is rare. This is a report of a case of recovery from confirmed paraquat poisoning in a imtoxicacion setting.

The dog exhibited the usual signs of paraquat poisoning. The diagnosis was confirmed on toxicological analysis of urine using an ion exchange technique. He recovered after seven weeks of intensive therapy. Alternative treatments are discussed. This compound is very notorious to cause rapid development of renal, rsticidas, and respiratory failure with very high mortality due to lack of specific antidote and dearth of high-quality evidence-based treatment.

Respiratory system involvement is the most common cause of death in these people. We hereby report a fatal case of a year-old male with a history of paraquat consumption.

The patient developed oliguric renal failure, deterioration of liver function, and acute respiratory distress syndrome over next few days. In this case, none of the strategies worked well, and death ensued due to multi-organ dysfunction syndrome.

The effects of paraquat in lungs are considered systemic effects. There are no dermal toxicity studies suitable for evaluation of systemic lung effects in the toxicity database for paraquat Paraquat raticidad among farmers in Korea after the ban.

The purpose of this study was intxoicacion examine the proportion of paraquat use intoicacion farmers and to describe their epidemiologic characteristics after the paraquat ban in We interviewed farmers in Korea in Farmers with longer farming experience, longer pesticide application years, and upland farming reported an increased risk of paraquat use although the trend was not statistically significant.

The majority of the farmers used preexisting paraquat Farmers who used paraquat perceived paraquat as a dangerous chemical; however, they disagreed with the necessity of the paraquat ban. Binding of paraquat to cell walls of paraquat resistant and susceptible biotypes of Hordeum glaucum.

Paraquat is a widely used, non-selective, light activated contact herbicide acting as a photosystem electron acceptor. Resistance to paraquat in weed species has occurred in Australia and world-wide following extensive use of this herbicide. The mechanism of resistance to paraquat in ‘Hordeum glaucum’ is correlated with reduced herbicide translocation and may be due to sequestration of herbicide away from its site of action by either binding to cell walls or other means.

We measured paraquat binding to a cell wall fraction in resistant and susceptible biotypes of H. The cell wall fraction was isolated from leaves of resistant and susceptible biotypes and incubated with 14 C-labelled paraquat. From kinetic experiments it seems that there are two types of binding sites in the cell wall with different affinities for paraquat. No significant differences between cell wall, characteristics of resistant and susceptible biotypes of H.

Therefore, increased binding of paraquat to the cell wall appears not to be a mechanism for intoxicacin of paraquat in resistant biotype. Paraquat -induced humano of mammalian cells.

The herbicide, paraquat methyl viologen, ‘ dimethy, 4’-bipyridinium dichloridestimulates the production of superoxide anion O 2 sup. In addition, concentrations of cellular glutathione are reduced by reaction with O 2 sup. It is reported here that paraquattoxic in its own right to aerobic cells, acts as a radiosensitizer when cells are exposed to nontoxic concentrations of the drug prior to and during irradiation.

The radiomimetic effect of paraquatalone and in combination with X-rays, was examined. Paraquat affects aerated cells hamster lung V79 cells in a dose-dependent manner. Doses in excess intkxicacion 1 mM for two hours cause significant cell killing.

In combination with radiation, sublethal doses of paraquatraticids for two hours prior to irradiation, enhance the lethal effects of radiation. However, if cells are exposed to the same concentration of paraquat following irradiation, no additional lethal effect is observed.

Paraquat is a useful tool to study the effects of O rahicidas sup. Acute kidney injury from Paraquat poisoning: Paraquat is a salt widely used as a herbicide. Although paraquat poisoning is rare in the general population, it may be considered as one of the most toxic poisons frequently used for suicide attempts, and is The autoradiographic localization of paraquat in the lung.

Paraquat poisoning in mammals results in ratkcidas characteristic lung lesion manifested principally as progressive pulmonary fibrosis. Paraquat is actively concentrated into the lung but the site of uptake remains undefined. A method is described for the autoradiographic localization of paraquat in rats. Preliminary evidence for humaanos site of uptake implicates the bronchiol. To evaluate whether the early pulmonary irradiation can prevent or decrease the pulmonary damage and contribute to improve ultimate survival in paraquat lung.

Fourteen of these patients were received pulmonary irradiation RT. All of the patients ere managed with aggressive supportive treatment such as gastric lavage, forced diuresis, antioxidant agents and antifibrosis agents.

Ingested amounts of paraquat were estimated into three groups A: Pulmonary irradiation was started within 24 hours after admission from day 1 to day 11 after ingestion of paraquat.

X 5 days was delivered without correction raticieas lung density. In group A, all patients were alive regardless of pulmonary irradiation and in group C, all of the patients were died due o multi-organ failure, especially pulmonary fibrosis regardless of pulmonary irradiation.

All 3 patients who were received pulmonary irradiation after 4 days after ingestion were died due to pulmonary fibrosis in spite of recovery from renal and hepatic toxicity.
