Review
Infectious diseases caused by pathogens and food poisoning caused by spoilage microorganisms are threatening human health all over the world. The efficacies of some antimicrobial agents, which are currently used to extend shelf-life and increase the safety of food products in food industry and to inhibit disease-causing microorganisms in medicine, have been weakened by microbial resistance. Therefore, new antimicrobial agents that could overcome this resistance need to be discovered. Many spices-such as clove, oregano, thyme, cinnamon, and cumin-possessed significant antibacterial and antifungal activities against food spoilage bacteria like Bacillus subtilis and , pathogens like Staphylococcus aureus and Vibrio parahaemolyticus, harmful fungi like Aspergillus flavus, even antibiotic resistant microorganisms such as methicillin resistant Staphylococcus aureus. Therefore, spices have a great potential to be developed as new and safe antimicrobial agents. This review summarizes scientific studies on the antibacterial and antifungal activities of several spices and their derivatives.

Review
Favism is a hemolytic disease due to the ingestion of fava beans in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency. There is wide inter- and intra-individual variability in the development of hemolytic crisis, and several factors influence it: quantity, quality, ripeness of fava beans, and age of onset. In this narrative review of case reports and case series, we reported the predisposing factors and clinical features for four different age groups classified as follows: pregnant women and infants (i.e., exclusively breastfed children); children, from weaned to 11 years; preadolescents and adolescents, from 11 to 18 years; and adults (18 years and older). Some symptoms developed only in specific age groups: death in infants; visual impairment in children; systolic murmur in infants, children, and adolescents; and renal failure in adults. In youngest children or pregnant women the severity is the highest. Some other symptoms were present in all: jaundice, increased bilirubin, splenomegaly, hepatomegaly, discolored urine, tachycardia, pallor, abdominal pain, malaise, vomit, nausea, and dizziness. Laboratory findings are characterized by anemia, reticulocytosis, elevated bilirubin level, and sometimes urinary urobilinogen and methemoglobinemia. In most cases the symptomatology is self-limited and does not release sequelae, but hospitalization and transfusion are often required.

BACKGROUND
Questions on poisoning by plants are a common reason for inquiries to poison information centers (PIC). Over the years 2011-2020, plant poisoning was the subject of 15% of all inquiries to the joint poison information center in Erfurt, Germany (Gemeinsames Giftinformationszentrum Erfurt, GGIZ) that concerned poisoning in children (2.3% in adults). In this patient collective, plant poisoning occupied third place after medical drugs (32%) and chemical substances (24%), and was a more common subject of inquiry than mushroom poisoning (1.5%).
METHODS
This review is based on pertinent publications retrieved by a selective literature search in PubMed/TOXLINE on plant poisoning and on 12 epidemiologically and toxicologically relevant domestic species of poisonous plants in risk categories 2 and 3 (up to 2021).
RESULTS
Medical personnel should have basic toxicological knowledge of the following highly poisonous plants: wolfsbane (aconitum), belladonna, angel's trumpet, cowbane (cicuta virosa), autumn crocus, hemlock, jimson weed, henbane, castor bean (ricinus), false hellebore, foxglove (digitalis), and European yew. The intoxication is evaluated on the basis of a structured history (the "w" questions) and the clinical manifestations (e.g., toxidromes). Special analysis is generally not readily available and often expensive and time-consuming. In case of poisoning, a poison information center should be contacted for plant identification, risk assessment, and treatment recommendations. Specimens of plant components and vomit should be obtained, if possible, for further testing. Measures for the elimination of the poisonous substance may be indicated after a risk-benefit analysis. Specific antidotes are available for only a few types of plant poisoning, e.g., physostigmine for tropane alkaloid poisoning or digitalis antibodies for foxglove poisoning. The treatment is usually symptomatic and only rarely evidence-based. Individualized medical surveillance is recommended after the ingestion of large or unknown quantities of poisonous plant components.
CONCLUSION
The clinician should be able to recognize dangerous domestic species of poisonous plants, take appropriate initial measures, and avoid overdiagnosis and overtreatment. To improve patient care, systematic epidemiological and clinical studies are needed.

Review
Substances toxic to the kidney are legion in the modern world. The sheer number and variety, their mutual interactions and, metabolism within the body are a challenge to research. Moreover, the kidney is especially prone to injury owing to its physiology. Acute kidney injury (AKI) induced by poisonous or primarily nephrotoxic substances, may be community acquired with ingestion or inhalation or nosocomial. Many nephrotoxic plants, animal poisons, medications, chemicals and illicit drugs can induce AKI by varying pathophysiological pathways. Moreover, the epidemiology of toxic AKI varies depending on country, regions within countries, socioeconomic status and health care facilities. In this review, we have selected nephrotoxic insults due to medication, plants, animal including snake venom toxicity, environmental, (agri)chemicals and also illicit drugs. We conclude with a section on diagnosis, clinical presentation and management of poisoning accompanied by various organ dysfunction and AKI.

UNLABELLED
A 46-year-old woman presented to the emergency room with acute onset of nausea, vomiting and prostration. She appeared ill and was poorly responsive to verbal stimuli. Physical examination showed a systolic blood pressure of 60 mmHg and a pulse of 40 bpm. ECG was notable for slight ST-elevations in the inferior leads. Right ventricular myocardial infarction with cardiogenic shock and bradycardia was suspected. Supportive therapy with catecholamines was initiated and an emergency coronary angiography was arranged. However, laboratory results showed normal troponin levels and a subsequent echocardiogram showed the absence of abnormal wall motion. Thorough history taking with the spouse revealed that the patient had consumed Turkish honey approximately 1 h before the symptoms began. The patient made a full recovery within 24 h with only supportive therapy. In retrospect, the clinical presentation was highly indicative of poisoning with grayanotoxins from the rhododendron plant, which contaminate some types of honey in the Black Sea area. A pollen analysis confirmed the presence of rhododendron in a honey sample. Historically this poisoning is referred to as mad honey disease. The ST-elevations in the ECG were a sign of early repolarization, a non-pathological finding.
LEARNING POINTS
ST-elevation in the inferior leads of an ECG in the context of hypotension and bradycardia does not always indicate right myocardial infarction.In the proper context, intoxication with grayanotoxins should be included in the differential diagnosis of hypotension and bradycardia.Study of diseases occurring in the past in a particular region offers the physician the chance to make a diagnosis otherwise missed.

Review
BACKGROUND
For many years, medicinal plants and herbal therapy have been widely used in different societies for the treatment of various diseases. Besides their therapeutic potency, some of the medicinal plants have strong toxicity in human, especially in children and elderly. Despite common beliefs that natural products are safe, there have been few reports on their toxicities.
MATERIALS AND METHODS
In the present study, we aimed to systematically review the literature wherein acute plant poisoning and herbal intoxication have been reported in pediatric patients. After literature search and selection of the appropriate documents, the desired data were extracted and described qualitatively.
RESULTS
A total of 127 articles with overall 1453 intoxicated cases were collected. The results of this study showed that some medicinal plants can cause acute poisoning and complications such as hepatic and renal failure in children.
CONCLUSION
The findings of this survey showed that acute plant poisoning can be life?threatening in children, and since a single?ingested dose of toxic plants can cause acute poisoning, parents should be aware of these toxic effects and compare the side effects of self?medication with its potential benefits.

Review
Cases of ingestion of indoor poisonous plants are relatively common among animals and lead to both acute cases of poisoning and long-term exposure to harmful substances and chronic damage to the animal's health. Plants produce a large number of secondary metabolites, which serve to protect the plant from attacks by insects, parasitic plants, fungi or, for example, during reproduction. However, these metabolites can be toxic if ingested by animals or humans. Toxicologically effective components found in plants are mainly alkaloids, glycosides, saponins, terpenes and others. This review article describes in detail the most common and popular indoor poisonous plants grown in Europe, the mechanisms of action of their active substances and clinical signs of the respective poisonings. This manuscript is supplemented with rich photographic documentation of these plants not found in similar articles, and also includes a description of the treatment of individual types of poisoning.

Review
Humins, humic and fulvic acids represent molecules with complex structures. These compounds comprising humic substances (HS) exist naturally in soil, brown coal, peat, and water. They are formed during the decomposition and transformation of organic matter (animal and plant remains) and their formation explains several theories. Within their chemical structures, there are numerous phenolic and carboxyl groups and their derivatives that affect their different properties, such as their solubility in water or their absorption of cations or mycotoxins. The manifold chemical structure of HS alters their polyelectrolyte character and thus their chelating efficiency. For many years, HS have been studied due to their detoxification, anti-, and pro-inflammatory or anticancer and antiviral ability. This article summarizes the antioxidant and adsorption properties of humic acids, highlighting their usefulness in intoxications.

Review
Bacillus cytotoxicus is a member of the Bacillus cereus group with the ability to grow at high temperatures (up to 52℃) and to synthesize cytotoxin K-1, a diarrhoeagenic cytotoxin, which appears to be unique to this species and more cytotoxic than the cytotoxin K-2 produced by other members of this group. Only a few isolates of this species have been characterized with regard to their cytotoxic effects, and the role of cytotoxin K-1 as a causative agent of food poisoning remains largely unclear. Bacillus cytotoxicus was initially isolated from a food-borne outbreak, which led to three deaths, and the organism has since been linked to other outbreaks all involving plant-based food matrices. Other studies, as well as food-borne incidents reported to the UK Food Standards Agency, detected B. cytotoxicus in insect-related products and in dried food products. With insect-related food becoming increasingly popular, the association with this pathogen is concerning, requiring further investigation and evidence to protect public health. This review summarizes the current knowledge around B. cytotoxicus and highlights gaps in the literature from a food safety perspective.
