Abstract
BACKGROUND AND AIMS Amanita phalloides poisoning causes severe liver damage which may be potentially fatal. Several treatments are available, but their effectiveness has not been systematically evaluated. We performed a systematic review to investigate the effect of the most commonly used therapies: N-acetylcysteine (NAC), benzylpenicillin (PEN), and silibinin (SIL) on patient outcomes. In addition, other factors contributing to patient outcomes are identified. METHODS We searched MEDLINE and Embase for case series and case reports that described patient outcomes after poisoning with amanitin-containing Amanita mushrooms. We extracted clinical characteristics, treatment details, and outcomes. We used the liver item from the Poisoning Severity Score (PSS) to categorize intoxication severity. RESULTS We included 131 publications describing a total of 877 unique cases. The overall survival rate of all patients was 84%. Patients receiving only supportive care had a survival rate of 59%. The use of SIL or PEN was associated with a 90% (OR 6.40 [3.14-13.04]) and 89% (OR 5.24 [2.87-9.56]) survival rate, respectively. NAC/SIL combination therapy was associated with 85% survival rate (OR 3.85 [2.04, 7.25]). NAC/PEN/SIL treatment group had a survival rate of 76% (OR 2.11 [1.25, 3.57]). Due to the limited number of cases, the use of NAC alone could not be evaluated. Additional analyses in 'proven cases' (amanitin detected), 'probable cases' (mushroom identified by mycologist), and 'possible cases' (neither amanitin detected nor mushroom identified) showed comparable results, but the results did not reach statistical significance. Transplantation-free survivors had significantly lower peak values of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total serum bilirubin (TSB), and international normalized ratio (INR) compared to liver transplantation survivors and patients with fatal outcomes. Higher peak PSS was associated with increased mortality. CONCLUSION Based on data available, no statistical differences could be observed for the effects of NAC, PEN or SIL in proven poisonings with amanitin-containing mushrooms. However, monotherapy with SIL or PEN and combination therapy with NAC/SIL appear to be associated with higher survival rates compared to supportive care alone. AST, ALT, TSB, and INR values are possible predictors of potentially fatal outcomes.

Abstract
OBJECTIVE The objective of this study was to present special clinical and laboratory features of 294 cases of mushroom poisoning. MATERIALS AND METHODS In this retrospective study, 294 patients admitted to the Pediatric and Adult Emergency, Internal Medicine and ICU Departments of Cumhuriyet University Hospital were investigated. RESULTS Of 294 patients between the ages of 3 and 72 (28.97 +/- 19.32), 173 were female, 121 were male and 90 were under the age of 16 years. One hundred seventy-three patients (58.8%) had consumed the mushrooms in the early summer. The onset of mushroom toxicity symptoms was divided into early (within 6 h after ingestion) and delayed (6 h to 20 d). Two hundred eighty-eight patients (97.9%) and six (2.1%) patients had early and delayed toxicity symptoms, respectively. The onset of symptoms was within two hours for 101 patients (34.3%). The most common first-noticed symptoms were in the gastrointestinal system. The patients were discharged within one to ten days. Three patients suffering from poisoning caused by wild mushrooms died from fulminant hepatic failure. CONCLUSION Education of the public about the consumption of mushrooms and education of health personnel working in health centers regarding early treatment and transfer to hospitals with appropriate facilities are important for decreasing the mortality.

Abstract
Survival rates of patients with acute liver failure (ALF) without transplantation are poor. However, many of them die awaiting a transplant because of the donor organ shortage. Supporting these patients until an organ becomes available or until their own liver is able to regenerate itself thus avoiding transplantation is a major goal in their multidisciplinary treatment. Animal experimental studies have shown that portal vein arterialization (PVA) enhances the regenerative capacity of hepatocytes by increasing the oxygen supply to the liver after extended hepatectomy or in toxin-induced ALF models. Furthermore, we have reported the application of PVA in patients with ALF. We herein have described the technical aspects of the PVA procedure both in preclinical models and in man.

Abstract
Survival rates of patients with acute liver failure (ALF) without transplantation are poor. Supporting these patients until an organ becomes available or until their own liver is able to regenerate itself, avoiding transplantation, is a major goal in the treatment of ALF. We report our clinical experience of portal vein arterialization in one case of massive liver necrosis after liver transplantation and in two patients with ALF caused by idiosyncratic drug reaction and mushroom intoxication. Portal vein arterialization, at least in two cases, was a turning point in the course of the disease since a close temporal association between surgery and clinical improvement was clearly evident. We believe that this novel approach, which should promote liver regeneration by providing an additional oxygen supply to the liver, may disclose a new possibility in the treatment of ALF and prompt new clinical and experimental research.

Abstract
BACKGROUND There is an increasing gap between the number of patients on the waiting list and the number of transplanted patients. In France, more than 10000 patients waited for an organ transplantation in 2002. Due to the graft shortage, "marginal" donors are now considered. The patients who present brain death after accidental or voluntary poisoning belong to this category. EPIDEMIOLOGY The data available from European or North American organ procurement organisations show that poisoned donors represent about 1% of all organ donors. It seems likely that a significant number of poisoned patients are not referred because poisoning is regarded as a contraindication to organ donation. When organ procurement can be achieved, the results expressed as recipient survival or graft survival are quite encouraging. TOXIC PRODUCTS The most frequently involved toxins are either drugs (psychotropic agents, analgesics...), illicit substances, or environmental agents (gases, alcohols...). The literature data are discussed; some issues remain controversial. PRACTICAL APPROACH Several criteria have to be applied when poisoned patients are considered as potential organ donors. Besides a firm diagnosis of "brain death", the knowledge of the "target organs" of poisoning is of paramount importance, together with careful analysis of the toxicokinetics and toxicodynamics. In most cases, routine biological and morphological data are sufficient to assess graft function.

Abstract
The terms extended donor or expanded donor mean changes in donor acceptability criteria. In almost all cases, the negative connotations of these terms cannot be justified. Factors considered to affect donor or organ acceptability have changed with time, after showing that they did not negatively affect graft or patient survival per se or when the adequate measures had been adopted. There is no age limit to be an organ donor. Kidney and liver transplantation from donors older than 65 years can have excellent graft and patient actuarial survival and graft function. Using these donors can be from an epidemiological point of view the most important factor to esablish the final number of cadaveric liver and kidney transplantations. Organs with broad structural parenchyma lesion with preserved functional reserve and organs with reversible functional impairment can be safely transplanted. Bacterial and fungal donor infection with the adequate antibiotic treatment of donor and/or recipient prevents infection in the latter. The organs, including the liver, from donors with infection by the hepatitis B and C viruses can be safely transplanted to recipients with infection by the same viruses, respectively. Poisoned donors and non-heart-beating donors, grafts from transplant recipients, reuse of grafts, domino transplant and splitting of one liver for two recipients can be an important and safe source of organs for transplantation.

Abstract
One hundred and forty-three cases (89 women and 54 men) of mushroom poisoning recorded at the emergency service of Osmangazi University Hospital, Faculty of Medicine, between 1996 and 2000 were evaluated. The first symptoms seen were loss of consciousness, fatigue, dizziness, severe headaches, abdominal discomfort and vomiting. The symptoms characteristically appeared suddenly. Eight patients suffering from poisoning caused by cultivated mushrooms, and four patients suffering from poisoning caused by wild mushrooms died from fulminant hepatic failure. The other patients were discharged within a period of 1-10 days. It is suggested that people should be informed of the possibility of mushroom poisoning, which has been increasing recently in Turkey.

Abstract
BACKGROUND Amatoxin poisoning is a medical emergency characterized by a long incubation time lag, gastrointestinal and hepatotoxic phases, coma, and death. This mushroom intoxication is ascribed to 35 amatoxin-containing species belonging to three genera: Amanita, Galerina, and Lepiota. The major amatoxins, the alpha-, beta-, and gamma-amanitins, are bicyclic octapeptide derivatives that damage the liver and kidney via irreversible binding to RNA polymerase II. METHODS The mycology and clinical syndrome of amatoxin poisoning are reviewed. Clinical data from 2108 hospitalized amatoxin poisoning exposures as reported in the medical literature from North America and Europe over the last 20 years were compiled. Preliminary medical care, supportive measures, specific treatments used singly or in combination, and liver transplantation were characterized. Specific treatments consisted of detoxication procedures (e.g., toxin removal from bile and urine, and extracorporeal purification) and administration of drugs. Chemotherapy included benzylpenicillin or other beta-lactam antibiotics, silymarin complex, thioctic acid, antioxidant drugs, hormones and steroids administered singly, or more usually, in combination. Supportive measures alone and 10 specific treatment regimens were analyzed relative to mortality. RESULTS Benzylpenicillin (Penicillin G) alone and in association was the mostfrequently utilized chemotherapy but showed little efficacy. No benefit was found for the use of thioctic acid or steroids. Chi-square statistical comparison of survivors and dead vs. treated individuals supported silybin, administered either as mono-chemotherapy or in drug combination and N-acetylcysteine as mono-chemotherapy as the most effective therapeutic modes. Future clinical research should focus on confirming the efficacy of silybin, N-acetylcysteine, and detoxication procedures.

Abstract
BACKGROUND Ecstasy is a neurotoxic and hepatotoxic drug. Brain edema and fulminant hepatic failure are two of the most serious complications associated with the consumption of ecstasy. Acute ecstasy intoxication can transform a patient into an organ donor or a hepatic graft recipient. MATERIALS AND METHODS In the last 5 years in our centers, we have had two multiorgan donors who died from ecstasy-induced brain edema and three patients who required urgent orthotopic liver transplantation for treatment of severe acute hepatocellular failure induced by this drug. We performed eight transplantations using the organs of these two brain-dead donors: one heart, one bipulmonary, three kidneys, one kidney-pancreas, and two livers. RESULTS Toxicity caused by ecstasy was not observed in any of the eight patients who underwent transplantation. The clinical state and the graft function of the heart, two liver, renopancreatic, and three kidney recipients were normal for a follow-up period that ranged between 7 months and 4.5 years. The lung recipient died from multiorgan failure secondary to bilateral pneumonia 5 days after the transplantation, and one of the kidney transplant patients died as a result of intestinal lymphoma 6 months after transplantation. The three liver transplantations in the three patients with ecstasy-induced fulminant hepatic failure were performed successfully using orthotopic transplantation. These three recipients are asymptomatic and have normal-functioning hepatic grafts after follow-up of 3.5 years, 15 months, and 11 months, respectively. CONCLUSIONS The thoracic and abdominal organs of people dying from ecstasy intoxication can be viable for transplantation. The short- and medium-term survival of the graft and of the recipient have been similar to that of other organ donors. Urgent liver transplantation is an effective therapeutic option in patients with ecstasy-induced acute hepatocellular failure.
