Plant Poisoning

Plant poisoning is a health concern in many countries where plants are used either accidently, especially among children, or intentionally for purposes such as assassination, suicide, hunting, fishing and treating various diseases. Presently, despite the implementation of toxicology surveillance systems in many countries, plant poisoning continues to be a preventable cause of morbidity and mortality. In the Aden governorate of Yemen, there are no laws or regulations for the prevention of plant poisoning, despite the existence of several poisonous species in gardens, and as roadside trees planted by the local authority, or growing wildly in public areas. In addition, there is a lack of scientific studies on the risks of these poisonous plants. Therefore, we undertook this study, based on scientific review, to document and illustrate the botanical, geographical and toxicological characteristics of fourteen poisonous plants collected from different districts of Aden governorate. The documented poisonous species (6 species) belong to Apocynaceae followed by Fabaceae (2 species), whereas Aristolochiaceae, Cucurbitaceae, Dracaenaceae, Euphorbiaceae, Meliaceae, and Verbenaceae are represented by one species each. The toxic parts of the majority of studied poisonous species are the whole plant, latex, seeds, and fruits. Cardiotoxicity, cytotoxicity, gastrointestinal toxicity, and inflammation of skin and mucous membrane are the main clinical manifestations. They are caused by varying amounts of plant toxins such as cardiac glycosides in Calotropis procera, Cryptostegia grandiflora, Nerium oleander and Thevetia peruviana, and cytotoxic toxins such as toxalbumins in Abrus precatorius and Ricinus communis, aristolochic acids in Aristolochia bracteolate, and vinca alkaloids in Catharanthus roseus, as well as gastrointestinal toxins such as cucurbitacins in Citrullus colocynthis, and tannins in Caesalpinia pulcherrima. Inflammation of skin and mucous membrane is caused by calcium oxalate crystals in Calotropis procera latex, and soluble protein in Cryptostegia grandiflora latex. Moreover, Azadirachta indica caused a number of toxicities attributed partially to tetranortriterpenoids, while Sansevieria trifasciata toxicity was reported to be low. The significance of this work is to promote the awareness among the local authority to take legal actions against plant poisoning. In addition, it provides the physicians with scientific information for the diagnosis and treatment of poisoning by some plants. It is hoped that this study motivates researchers to conduct further research on poisonous plants throughout Yemen.

Currently, rhinitis accompanied by nasal obstruction is one of the most common diseases in children and adolescents. Regardless of the cause of its occurrence - an infectious or non-infectious (allergic) process, each time there is a vascular (vasomotor) reaction. In children of preschool and primary school age, the most common is infectious rhinitis, which develops with viral and bacterial infections. The group of non-allergic rhinitis, which develops more often in adolescents, is united by the term idiopathic (vasomotor) rhinitis.Purpose of the study. Evaluation of the effectiveness of the use of a complex preparation containing calendula, witch hazel, esculus, menthol and zinc oxide in the treatment of vasomotor rhinitis in children.Materials and methods. The study included 40 patients of childhood and adolescence, of both sexes (23 girls and 17 boys) aged 6 to 14 years with an established diagnosis of vasomotor (idiopathic) rhinitis, without concomitant pathology, not registered with specialists, without constant admission The study drug was used to lubricate the mucous membrane of the nasal cavity or put turundas with ointment for 3-5 minutes 2-3 times a day. The course of treatment was 7-10 days. The effectiveness of treatment was assessed by the dynamics of clinical data and the severity of the subjective symptoms of the disease.Results. A comparisons of these scores for re-assessing the status of patients relative to the timing of the study drug use showed a uniform positive trend in terms of the clinical picture and subjective complaints of patients.Conclusions. The inclusion in the complex therapy of pediatric patients with idiopathic (vasomotor) rhinitis of the drug Fleming’s Ointment, or monotherapy with this agent, contributes to a  rapid and pronounced weakening of  the  clinical manifestations of the disease, allowing you to quickly achieve positive treatment results in the form of relief of nasal obstruction, rhinorrhea, edema of the mucous membrane of the cavity nose, sneezing. There is a positive trend in the state of the mucous membrane itself.

Introduction. Gastric duplication cyst is a rare clinical observation. More often, these cysts are localized in the fundus or body of the stomach and have a common muscle layers and blood supply. Even more rarely, duplication cysts are not anatomically connected to the stomach and are located in other parts of the abdominal cavity or in the retroperitoneal space. Cystic duplication of the gastrointestinal tract, which are localized in the pancreas, is extremely rare. The aim of the study is to demonstrate the possibility of using laparoscopy for this disease. Materials and methods. The paper describes three rare clinical observations of gastric duplication cyst topographically associated with the pancreas. In the first clinical observation, gastric duplication cyst was combined with mediastinal duplication cysts, an esophageal bronchial fistula, and extralobar pulmonary sequestrations. In the second observation, a duplication cyst had communication with the pancreatic duct system and was clinically manifested by recurrent bleeding. In the third case, a duplication cyst is diagnosed behind the body and tail of the pancreas. Results. In all cases, surgical treatment was carried out by the laparoscopic method, leading to complete recovery. Histological examination in all the described observations confirmed the gastric type of epithelium of the mucous membrane of the cysts. The article provides a review of the literature. Conclusion. Thus, the efficiency of laparoscopic interventions in children with gastric duplications topographically associated with the pancreas was demonstrated. The described rare clinical manifestations, a combination of defects, as well as the possible presence of heterotopy of the mucous membrane of the duplication cyst confirm the need for surgical correction of the disease.

Abstract Background: Listeriosis is a rare but severe foodborne infectious disease. Perinatal listeriosis is often associated with septicemia, central nervous system (CNS) infection, and serious adverse pregnancy outcomes (miscarriage and neonate death). Here we report the characteristics and outcomes of perinatal listeriosis cases treated over 6 years at Beijing Obstetrics and Gynecology Hospital (BOGH), the largest maternity hospital in China. Methods: We retrospectively reviewed the records of laboratory-confirmed, pregnancy-associated listeriosis cases treated from January 1, 2013 to December 31, 2018. The clinical manifestations, laboratory results, perinatal complications and outcomes (post-natal follow-up of 6 months) were investigated. Results: In BOGH, 12 perinatal listeriosis cases were diagnosed based on Listeria monocytogenes positive culture, including 10 single pregnancies and 2 twin pregnancies. The corresponding incidence of pregnancy-associated listeriosis was 13.7/100,000 deliveries. Among those cases, four pregnant women and four newborns had septicemia, and two of the neonates with septicemia also suffered CNS infection. All the maternal patients recovered. Two inevitable miscarriages and four fetal stillbirths occurred. Of the eight delivered newborns, six survived, and two died within 2 days from birth. None of the survivors had neurological sequelae during a 6-month follow-up. The overall feto-neonatal fatality rate was 57.1%; notably, this rate was 100% for infections occurring during the second trimester of pregnancy and only 14.3% for those occurring in the third trimester. Conclusions: Perinatal listeriosis is associated with high feto-neonatal mortality, and thus, a public health concern. Additional large-scale studies are needed to strengthen the epidemiological understanding of listeriosis in China.

Novel Coronavirus

Over the past two decades, there have been two major outbreaks where the crossover of animal Betacoronaviruses to humans has resulted in severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). In December 2019, a global public health concern started with the emergence of a new strain of coronavirus (SARS-CoV-2 or 2019 novel coronavirus, 2019-nCoV) which has rapidly spread all over the world from its origin in Wuhan, China. SARS-CoV-2 belongs to the Betacoronavirus genus, which includes human SARS-CoV, MERS and two other human coronaviruses (HCoVs), HCoV-OC43 and HCoV-HKU1. The fatality rate of SARS-CoV-2 is lower than the two previous coronavirus epidemics, but it is faster spreading and the large number of infected people with severe viral pneumonia and respiratory illness, showed SARS-CoV-2 to be highly contagious. Based on the current published evidence, herein we summarize the origin, genetics, epidemiology, clinical manifestations, preventions, diagnosis and up to date treatments of SARS-CoV-2 infections in comparison with those caused by SARS-CoV and MERS-CoV. Moreover, the possible impact of weather conditions on the transmission of SARS-CoV-2 is also discussed. Therefore, the aim of the present review is to reconsider the two previous pandemics and provide a reference for future studies as well as therapeutic approaches.

Enterohaemorrhagic Escherichia Coli

Consumption of foods, water, vegetables, fruits, undercooked/ground/raw meat, unpasteurized milk or milk products contaminated with the bacterium strain Escherichia coli 0157:H7 has become a serious public health concern. This strain naturally inhabits the digestive tract of healthy cattle, and is released into the environment through the faeces of the animal. This strain cause haemorrhagic enterocolitis or gastroenteritis, and then haemolytic uraemic syndrome (HUS). HUS is a disorder characterised by haemolytic anaemia, low platelet count and acute kidney failure, and this disorder is a consequence of the production and action of Shiga-like toxin produced mainly by this bacterial strain (accounting for 90 percent of all cases), and occurs mainly in children less than five (5) years of age, but also occurs in the elderly. After infection with this bacterial strain, the disorder begins with intestinal perforation and ulceration leading to bloody diarrhoea, and consequently acute kidney injury, thrombocytopenia and microangiopathic haemolytic anaemia. In conjunction with clinical manifestations, several laboratory investigations (haematological, biochemical and microbiological assays) are implicated in the diagnosis of HUS. There is currently no specific treatment for HUS; however, supportive care (such as treatment of hypertension, fluid and electrolyte imbalance, haemodialysis, blood transfusion, etc) happens to be the only ameliorative measure for this disorder.

AbstractGlucose-6-phosphate dehydrogenase (G6PD) deficiency, the most common genetic defect and enzymopathy with a wide distribution and increased public health concern, predisposes subjects succumb to oxidative stress. G6PD deficiency has been associated with hemolysis. Clinically, G6PD deficiency is asymptomatic and the clinical manifestations occur with the exposure to certain agents. Due to the lack of suitable animal models that can predict the clinical hemolytic potential of drugs, it needs an appropriate research model to fully recapitulate the manifestations of G6PD deficiency in clinic, to optimize the malaria therapy and promote anti-malarias development. The present study has displayed a stable transgenic Tg(zgata1-g6pdM118-144-egfp) zebrafish model with G6PD deficiency which mimics the clinical features of G6PD deficiency phenotypically and functionally. The findings showed that there was an inadequate level of reduced GSH in the transgenic Tg(zgata1-g6pdM118-144-egfp) zebrafish line in the presence or absence of α-naphthol, compared to the wildtype zebrafish, indicating an attenuation of g6pd activity in the transgenic zebrafish line. In addition, the observations show that there is a less abundance of g6pd in the transgenic Tg(zgata1-g6pdM118-144-egfp) zebrafish line. On the other hand, there is no morphological abnormality in the transgenic Tg(zgata1-g6pdM118-144-egfp) zebrafish line. Taken together, our work has delivered a novel stable transgenic zebrafish model of G6PD deficiency that will facilitate the mechanistic and functional elucidation for the role of G6PD in erythrocytic pathophysiology. This model will promote the translational research for the drug development, in particular, for anti-malarias development.

Background: Plant poisoning is a common scenario in a toxicology unit . Some of the plants contain active components used as medicines. However, some of the plant constituents are poisonous with wide variety of clinical manifestations. Authors aimed to study the pattern of various types of plant poisons and clinical presentations and complications of various plant poisons admitted in our toxicological unit.Methods: A total of 87 patients admitted with history of plant poison ingestion, in toxicological unit of Tirunelveli medical college were studied . It was a retrospective observational study and was done over a period of one year.Results:  Out of 87 cases studied, 92%were due to consumption with suicidal intention. Plant poisoning ranks second only to pesticide poisoning . among the plant poisons encountered 66.6% were due to Oleander poison, followed by Datura (8%) and Glory lily(5.7%). Common parts of plant consumed by patients include seeds and plant oils . Vomiting and abdominal pain were the commonest presentations. Encephalopathy, dyselectrolytemia and arrhythmias were the notable complications in our study.Conclusions: Early admission and prompt first aid and monitoring at tertiary care center are key to the reduced mortality. The study throws light on various manifestations, toxic parts and complications of plant poisons.

Human thelaziasis is an emerging insect-borne zoonotic ocular parasitic infestation, occur more commonly in rural communities with poor living and low socioeconomic living, and mainly affects the children and old age people, where humans live in close proximity with animals. Human thelaziasis is caused by both Thelazia callipaeda and Thelazia californiensis. T. callipaeda lives under the eye lids, nictitating membranes, orbit, conjunctival sac, lachrymal glands, and lacrimal ducts of cats, dogs, rabbits, horses, cattle, deer, badgers, monkeys, wolves, foxes (definitive hosts) and man being an accidental host. The vectors (intermediate hosts) are non-biting, tear-seeking, diptera flies of family Drosophilidae (fruit flies) Phortica variegata, which feeds on tears of their definitive hosts, including humans. Clinical manifestations include conjunctivitis, lacrimation, itching or pain with foreign body sensation, epiphora, follicular hypertrophy, and less often with severe signs and symptoms such as keratitis, photophobia, ectropion, corneal opacities (due to the migration of worm across the cornea), floaters within the eye chamber leading to visual impairment/blindness. The knowledge and scientific information on human thelaziasis is still unknown or relatively limited to many ophthalmologists and clinicians, and received little attention; hence this comprehensive and systematic review of human thelaziasis, is undertaken to highlight its importance and further research.

Phytobiocides are a good alternative to chemicals in managing bacterial diseases including bacterial wilt of tomato caused by Ralstonia solanacearum. In the present research study, finely ground dried powders of seven widely available medicinal plants/weeds species viz., Peganum harmala (esfand or wild rue), Calotropis procera (sodom apple), Melia azedarach (white cedar), Allium sativum (garlic), Adhatoda vasica (malabar nut), Tagetes patula (marigold) and Nerium oleander (oleander) were assessed for their anti-microbial activity, both in-vitro (10% w/v) and in-vivo (10, 20, 30, and 40 g/kg of potted soil) against R. solanacearum. Aqueous extracts (prepared as 10% w/v, soaking for 48-72 h and filtering) of C. procera, A. vasica, and T. patula inhibited the in-vitro growth of the bacterial pathogen over 60% of that produced by the standard antibiotic streptomycin. A. sativum, N. oleander and P. harmala aqueous extracts were less effective while M. azedarach showed no effect against R. solanacearum. The higher dose (40 g/kg of soil) of C. procera, A. vasica and T. patula decreased disease severity quite effectively and increased yield and plant growth characters as much as the standard antibiotic did. No phytotoxicity of medicinal plants powder was observed on tomato plants. Alkaloids, flavonoids, tannins, saponins and terpenoids were detected in the aqueous extracts of T. patula and A. vasica whereas C. procera was found to have only alkaloids, flavonoids, tannins and saponins. Our data suggest that dried powders of T. patula, C. procera and A. vasica (40 g/kg of soil) could be used as an effective component in the integrated disease management programs against bacterial wilt of tomato.
