Non vitamin-K oral anticoagulants (NOACs) are direct and specific inhibitors of the coagulation factors IIa (dabigatran) and Xa (apixaban, rivaroxaban, edoxaban) which share many pharmacokinetic properties. However, indications are lacking regarding the use of NOACs during thrombolysis, surgery and bleeding events. Areas covered: In this paper, the authors retrospectively analyzed the relevant literature on the NOACs using the PubMed and Google Scholar databases. Expert Commentary: Although warfarin is effective in cardioembolic stroke prevention, easier handling and more favorable risk-benefit profile often render NOACs a more preferable therapy choice for neurologists...

Ricardo Espinoza González
Gastrointestinal bezoars are a concretion of indigested material that can be found in the gastrointestinal tract of humans and some animals. This material forms an intraluminal mass, more commonly located in the stomach. During a large period of history animal bezoars were considered antidotes to poisons and diseases. We report a historical overview since bezoars stones were thought to have medicinal properties. This magic conception was introduced in South America by Spanish conquerors. In Chile, bezoars are commonly found in a camelid named guanaco (Lama guanicoe)...

In recent years the options of anticoagulant/antithrombotic therapy have extended with new - direct oral anticoagulants, comprising direct thrombin inhibitors (dabigatran etexilate) and direct factor Xa inhibitors (rivaroxaban, apixaban). These agents represent another progress towards "the ideal antithrombotic drug", and thus towards a safe and effective antithrombotic therapy. The following article provides actual review and recommendations for clinical practice, including laboratory assessment and management of emergency situations...

REVIEW
Michael Gitlin
Despite its virtually universal acceptance as the gold standard in treating bipolar disorder, prescription rates for lithium have been decreasing recently. Although this observation is multifactorial, one obvious potential contributor is the side effect and toxicity burden associated with lithium. Additionally, side effect concerns assuredly play some role in lithium nonadherence. This paper summarizes the knowledge base on side effects and toxicity and suggests optimal management of these problems. Thirst and excessive urination, nausea and diarrhea and tremor are rather common side effects that are typically no more than annoying even though they are rather prevalent...

Organophosphate (OP) compounds are extremely toxic chemicals that may be absorbed via skin, conjunctiva, gastrointestinal and respiratory systems. Treatment of OP poisoning is a critical and aggressive process which includes decontamination, antidote administration (atropin and oximes), mechanical ventilation support and extracorporeal elimination procedures if needed. Here we present a young female patient who was unintentionally poisoned by an OP (trichlorfon) after using it to moisture her skin. The importance of this patient is the dermal disease that makes her unprotective to dermal exposure of chemicals and application of plasmapheresis to treat her poisoning...

Bothrops erythromelas is a snake of medical importance responsible for most of the venomous incidents in Northeastern Brazil. However, this species is not included in the pool of venoms that are used in the Brazilian polyvalent bothropic antivenom (BAv) production. Furthermore, it is well known that antivenom therapy has limited efficacy against venom-induced local effects, making the search for complementary alternatives to treat snakebites an important task. Jatropha gossypiifolia is a medicinal plant widely indicated in folk medicine as an antidote for snakebites, whose effectiveness against Bothrops jararaca venom (BjV) has been previously demonstrated in mice...

According to the NIH, about 275000 patients receive treatment with 5-Fluorouracil (5-FU) and more than 1300 die from 5-FU toxicity every year from life-threatening myelosuppression, gastrointestinal complications, and neurotoxicity. Immunocompromised persons are at higher risk of developing toxicity. Recently uridine triacetate (Vistagard®) has been approved by the Food and Drug Administration (FDA) as the only specific antidote available for 5-FU poisoning. In a clinical trial (n=135), 96% of patients with 5-FU toxicity recovered after treatment, where as in a historical control group only 10% survived...

Malignant hyperthermia (MH) is a rare life threatening inherited disorder that is triggered by drugs used for general anesthesia in susceptible persons. The symptoms include rapid increase of body temperature and severe muscle contractions. The present study includes 3 cases of MH and highlights the timely identification of symptoms for rescuing the patient. In case I, a 7-year-old male child underwent surgery with ketamine at a dose of 250 mg. After 4 h of operation, the child went through convulsions, high fever and succumbed within a few hours...

The farnesoid X receptor (FXR) is a ligand-activated transcription factor that plays important roles in regulating bile acid homeostasis. The aim of the present study was to investigate the effects of obeticholic acid (OCA), a novel synthetic FXR agonist, carbon tetrachloride (CCl4)-induced acute liver injury. Mice were intraperitoneally injected with CCl4 (0.15ml/kg). In CCl4+OCA group, mice were orally with OCA (5mg/kg) 48, 24 and 1h before CCl4. As expected, hepatic FXR was activated by OCA. Interestingly, OCA pretreatment alleviated CCl4-induced elevation of serum ALT and hepatic necrosis...

The roman philonium (Philonium Romanum) is an example of pharmacological poetry. This opiate was conceived by Philo of Tarsus, who was active during the first century of the Common Era. His antidote was written in elegiac couplets. The conservation of these couplets is owed to Galen, who reproduced them in the ninth book of On the Composition of Medicines according to the Places. Most of this Galenic treatise has not been translated into Spanish. For the first time, we offer this prescription in our language from a French version of the fin de siècle...

Intoxications may lead to life-threatening emergencies. While stabilising the patient, therapy should focus on a rapid and effective elimination of the toxin. General measures for decontamination (gastrointestinal, dermal, ocular) aim to effectively decrease the absorption of the poisonous substance. Further classification of the substance and its properties can assist with the choice of specific treatment options, including dialysis and specific antidotal therapy. In recent years, treatment with lipid emulsions for enhanced elimination of lipophilic substances has become an important therapeutic option...

Drug-induced liver injury (DILI) can be predictable or idiosyncratic and has an estimated incidence of approximately 20 cases per 100,000 persons per year. DILI is a common cause of acute liver failure in the United States. No accurate tests for diagnosing DILI exist, and its diagnosis is based on exclusion of other conditions. Managing DILI includes discontinuing the suspected causative agent and in selected cases administering an antidote. Liver support systems are used for long-term support or as a bridge to transplantation and are effective for improving encephalopathy, hyperbilirubinemia, and other liver-related conditions, but whether they improve survival remains uncertain...

OBJECTIVE: The authors present the guidelines of the French Society of Otorhinolaryngology concerning the management of epistaxis during antithrombotic therapy. METHODS: A review of the literature was performed by a multidisciplinary work group. Guidelines were drafted, then re-edited by a reading group independent of the work group to produce the final text. The proposed recommendations were graded A, B, C or expert opinion, on decreasing levels of evidence. RESULTS: Before any decision to modify antithrombotic treatment, it is recommended to screen for overdose and assess the risk of thrombosis...

BACKGROUND: Antidotes stocking is a critical component of hospital care for poisoned patients in emergency. Antidote stocking represents a major health challenge worldwide and in Lebanon. Systematic data monitoring of antidote stocking in Lebanese hospitals is lacking. The objective of this study is to assess the adequacy of antidotes stocking in Lebanese hospitals according to type and quantity and explore the characteristics associated with their differential availability. METHODS: Data collection to assess antidote availability and its correlate was undertaken through a self-administered questionnaire...

Bupivacaine toxicity following accidental overdose still lacks therapeutic solution. However, there are major arguments for testing BPC 157 against bupivacaine toxicity in vivo in rats, in particular, and then finally, in vitro. These are: the lack of any known BPC 157 toxicity, a lifesaving effect via the mitigation of arrhythmias in rats underwent hyperkalemia or digitalis toxicity, the elimination of hyperkalemia and arrhythmias in rats underwent succinylcholine toxicity and finally, the reduction of potassium-induced depolarization in vitro (in HEK293 cells) in severe hyperkalemia...

Long-term exposure to arsenic has been known to induce neoplastic initiation and progression in several organs; however, the role of arsenic (As2 O3 ) in oxidative stress-mediated DNA damage remains elusive. One of the immediate cellular responses to DNA damage is poly(ADP-ribosyl)ation (PARylation), which mediates DNA repair and enhances cell survival. In this study, we found that oxidative stress (H2 O2 )-induced PARylation was suppressed by As2 O3 exposure in different human cancer cells. Moreover, As2 O3 treatment promoted H2 O2 -induced DNA damage and apoptosis, leading to increased cell death...

The recent emergence of resistance, toxicity paradigm and limited efficacy of conventional antifungal drugs necessitate the identification of de novo targets in fungal metabolism. One of the most critical physiological processes during in vivo pathogenesis is maintenance of iron homeostasis. The most life threatening opportunistic human fungal pathogens like Aspergillus, Candida and Cryptococcus exploit the siderophore mediated iron uptake mechanism either for survival, virulence, propagation or resistance to oxidative stress envisaged in vivo during infection...
