Botulismo en la UCI: proceso de cuidados / Botulism in the ICU: nursing care plan

Introducción y valoración del caso. El botulismo es una enfermedad poco frecuente en Europa, causada por la bacteria Clostridium botulinum, de declaración obligatoria, no transmisible de persona a persona y potencialmente mortal (entre un 5 y 10%) si no se trata rápidamente. Se obtuvo el dictamen favorable del Comité de Ética de Investigación Clínica. Se presenta el proceso de cuidados enfermero de un varón de 49 años con diagnóstico de intoxicación bacteriana por Clostridium botulinum, secundario a la ingesta de alubias en mal estado, que estuvo ingresado en la UCI un total de 35 días. Diagnósticos y planificación. Valoración enfermera de forma holística durante las primeras 24 h, con priorización de los sistemas que presentaron un deterioro más rápido: el neurológico y el respiratorio. Se priorizaron 9 diagnósticos según la taxonomía NANDA: riesgo de respuesta alérgica, patrón respiratorio ineficaz, deterioro de la mucosa oral, deterioro de la movilidad física, riesgo de síndrome de desuso, riesgo de motilidad gastrointestinal disfuncional, deterioro de la eliminación urinaria, riesgo de confusión aguda y riesgo de cansancio del rol del cuidador. Discusión. El proceso de cuidados enfermero, estandarizado y organizado con la taxonomía NANDA y priorizado con el método sistemático AREA, garantizó los mejores cuidados basados en la evidencia y prueba de ello fue la mejoría de las puntuaciones de los indicadores de resultado NOC. Resultó imposible comparar la actuación enfermera con la de otros casos documentados

Introduction and case evaluation. Botulism is a rare disease in Europe, caused by the bacterium Clostridium botulinum, notifiable, non-transmissible person-to-person and potentially fatal (between 5 and 10%) if not treated quickly. The favourable opinion of the Clinical Research Ethics Committee was obtained. We present the nursing care plan of a 49-year-old man with a diagnosis of bacterial intoxication caused by Clostridium botulinum, secondary to ingestion of beans in poor condition, who was admitted to the ICU for a total of 35 days. Diagnosis and planning. Holistic nursing evaluation during the first 24hours, with prioritisation of the systems that were deteriorating fastest: neurological and respiratory. Nine diagnoses were prioritised according to the NANDA taxonomy: Risk for allergy response, Ineffective breathing pattern, impaired oral mucous membrane, Impaired physical mobility, Risk for disuse syndrome, Risk for dysfunctional gastrointestinal motility, Impaired urinary elimination, Risk for acute confusion and Risk for caregiver role strain. Discussion. The nursing care plan, standardised and organised with the NANDA taxonomy and prioritised with the outcome-present state-test (OPT) model, guaranteed the best care based on evidence, as the NOC scores improvement demonstrated. It was impossible to compare the nursing intervention with other case reports

Metahemoglobinemia relacionada con ingesta de puré de acelgas / Methemoglobinemia due to ingestion of chard puree

La metahemoglobinemia es un síndrome clínico dado por la presencia de una forma aberrante de hemoglobina, ocasionada por diversos agentes oxidantes. Se describe un caso clínico de metahemoglobinemia severa asociada a la ingesta de puré de acelgas con alto contenido en nitratos y nitritos. Paciente de un año, con antecedentes de comunicación interauricular (CIA), que presentó un cambio en coloración de la piel 7 h antes, en forma progresiva, acompañado de vómitos. Ingresó al Departamento de Emergencia con cianosis generalizada que no mejoró con oxigenoterapia, taquicardia y tendencia a hipotensión arterial. En cuidados intensivos se realizó ecocardiograma que evidenció CIA sin repercusión hemodinámica. Metahemoglobinemia 37%. Se realizó dosis de azul de metileno al 1% por vía intravenosa, con franca mejoría clínica a la hora de la administración del antídoto y descenso de niveles de metahemoglobina. Alta médica a las 36 horas del ingreso. Existía una relación cronológica entre la exposición a nitratos por ingesta de un puré de acelgas y la aparición del cuadro. Los niveles de nitratos hallados en dicho alimento fueron muy elevados considerando estándares internacionales, lo que sumado a una inadecuada conservación del alimento cocido los días previos, permitió confirmar el planteo etiológico realizado. Resulta importante sospechar esta entidad patológica poco frecuente frente a cianosis que no mejora con oxígeno, y prevenir cuadros similares al descrito mediante una adecuada manipulación y conservación de las verduras con alto contenido en nitratos.

Methemoglobinemia is a clinical syndrome due to the presence of an aberrant form of hemoglobin, caused by various oxidizing agents. The study reports a case of severe methemoglobinemia associated with the ingestion of chard puree with high levels of nitrates and nitrites. A 1-year-old patient with a history of atrial septal defect (ASD), who progressively showed change of skin color 7 hours earlier, accompanied by vomiting. She was admitted to the Emergency Department with generalized cyanosis not improving with oxygen therapy, tachycardia and tendency to hypotension. In the intensive care unit, an echocardiogram showed ASD without hemodynamic complications. Methemoglobinemia 37%. A 1% methylene blue dose was administered intravenously, with clinical improvement one hour after antidote administration and decrease in methemoglobin levels. Medical discharge at 36 hours of admission. There was a chronological relationship between nitrates exposure by ingestion of chard puree and the clinical onset of methemoglobinemia. The toxic cause was confirmed after high nitrates levels were found in this vegetable considering international standards, and an inadequate preservation of the cooked chard on previous days. It is important to suspect this rare pathological entity when cyanosis fails to improve with oxygen, and to prevent poisonings similar to those described by an adequate manipulation and preservation of vegetables with high nitrate levels.

Unintentional ingestion of Cordyceps fungus-infected cicada nymphs causing ibotenic acid poisoning in Southern Vietnam.

BACKGROUND: Cordyceps fungus found in infected cicada nymphs ("cicada flowers") is utilized in traditional Chinese medicine. Cordyceps fungus toxicity in humans has not been previously reported. We report 60 cases of apparent Cordyceps poisoning in Southern Vietnam. METHODS: We retrospectively collected demographic and clinical data from the medical records (21 cases) and by telephone interview (39 cases) of patients admitted to seven hospitals in Southern Vietnam following ingestion of cicada flowers between 2008 and 2015. We also determined the species of Cordyceps present in the cicada flowers and performed a partial chemical analysis of the fungus. RESULTS: Sixty cases of toxic effects following ingestion of cicada flowers were documented. Symptom onset occurred within 60 minutes following ingestion. Symptoms included dizziness, vomiting, salivation, mydriasis, jaw stiffness, urinary retention, seizures, agitated delirium, hallucinations, somnolence and coma. None of the patients suffered liver or kidney injury. There was one fatality. The Cordyceps fungus involved in these poisoning was identified as Ophiocordyceps heteropoda. The presence of ibotenic acid was confirmed, but musimol and muscarine were absent. CONCLUSIONS: Cicada infected with Ophiocordyceps heteropoda in Vietnam contain ibotenic acid and are associated with a clinical syndrome consistent with its effects.

Arcobacter: an emerging food-borne zoonotic pathogen, its public health concerns and advances in diagnosis and control - a comprehensive review.

Arcobacter has emerged as an important food-borne zoonotic pathogen, causing sometimes serious infections in humans and animals. Newer species of Arcobacter are being incessantly emerging (presently 25 species have been identified) with novel information on the evolutionary mechanisms and genetic diversity among different Arcobacter species. These have been reported from chickens, domestic animals (cattle, pigs, sheep, horses, dogs), reptiles (lizards, snakes and chelonians), meat (poultry, pork, goat, lamb, beef, rabbit), vegetables and from humans in different countries. Arcobacters are implicated as causative agents of diarrhea, mastitis and abortion in animals, while causing bacteremia, endocarditis, peritonitis, gastroenteritis and diarrhea in humans. Three species including A. butzleri, A. cryaerophilus and A. skirrowii are predominantly associated with clinical conditions. Arcobacters are primarily transmitted through contaminated food and water sources. Identification of Arcobacter by biochemical tests is difficult and isolation remains the gold standard method. Current diagnostic advances have provided various molecular methods for efficient detection and differentiation of the Arcobacters at genus and species level. To overcome the emerging antibiotic resistance problem there is an essential need to explore the potential of novel and alternative therapies. Strengthening of the diagnostic aspects is also suggested as in most cases Arcobacters goes unnoticed and hence the exact epidemiological status remains uncertain. This review updates the current knowledge and many aspects of this important food-borne pathogen, namely etiology, evolution and emergence, genetic diversity, epidemiology, the disease in animals and humans, public health concerns, and advances in its diagnosis, prevention and control.

Antibacterial Activities of Ankaferd Hemostat (ABS) on Shiga Toxin-Producing Escherichia coli and Other Pathogens Significant in Foodborne Diseases.

OBJECTIVE: Ankaferd hemostat (Ankaferd Blood Stopper®, ABS)-induced pharmacological modulation of essential erythroid proteins can cause vital erythroid aggregation via acting on fibrinogen gamma. Topical endoscopic ABS application is effective in the controlling of gastrointestinal (GI) system hemorrhages and/or infected GI wounds. Escherichia coli O157:H7, the predominant serotype of enterohemorrhagic E. coli, is a cause of both outbreaks and sporadic cases of hemorrhagic colitis. The aim of this study is to examine the effects of ABS on 6 different Shiga toxigenic E. coli serotypes including O26, O103, O104, O111, O145, and O157 and on other pathogens significant in foodborne diseases, such as Salmonella Typhimurium, Campylobacter jejuni, and Listeria monocytogenes, were also assessed. MATERIALS AND METHODS: All strains were applied with different amounts of ABS and antimicrobial effect was screened. S. Typhimurium groups were screened for survival using the fluorescence in situ hybridization technique. RESULTS: The relative efficacy of ABS solutions to achieve significant logarithmic reduction in foodborne pathogens E. coli O157:H7 and non-O157 serogroups and other emerging foodborne pathogens is demonstrated in this study. ABS has antibacterial effects. CONCLUSION: Our present study indicated for the first time that ABS may act against E. coli O157:H7, which is a cause of thrombotic thrombocytopenic purpura, hemolytic-uremic syndrome, and hemorrhagic colitis. The interrelationships between colitis, infection, and hemostasis within the context of ABS application should be further investigated in future studies.

Electromyographic and laboratory findings in acute Solanum torvum poisoning.

CONTEXT: Solanum torvum berries, known as susumber or turkey berries, are prepared as part of traditional Jamaican dishes usually served with cod and rice. Poisoning is rare. Although toxic compounds have never been definitively isolated, previous reports suggest toxicity results from inhibition of acetylcholinesterases. We present a case of susumber berry poisoning with detailed electromyographic studies and laboratory analysis. CASE DETAILS: A 54-year-old woman presented to the Emergency Department (ED) complaining of vision, speech, and gait changes; emesis; and diffuse myalgias following consumption of susumber berries. The physical examination demonstrated an intact, lucid mental status, miosis, opsoclonus, severe dysarthria, dysmetria, mild extremity tenderness and weakness, and inability to ambulate. Her symptom constellation was interpreted as a stroke. DISCUSSION: Electromyography demonstrated a pattern of early full recruitment as well as myotonia during the period of acute toxicity. Additionally, solanaceous compounds, in particular solasonine and solanidine, were identified in leftover berries and the patient's serum. Store-bought commercial berries and subsequent serum samples were free of such toxic compounds. EMG studies, together with a laboratory analysis of berries or serum can assist in the differential diagnosis of stroke, and provide both a prognostic screening and confirmation of suspected glycoside toxicity.

Histamine, histamine intoxication and intolerance.

Excessive accumulation of histamine in the body leads to miscellaneous symptoms mediated by its bond to corresponding receptors (H1-H4). Increased concentration of histamine in blood can occur in healthy individuals after ingestion of foods with high contents of histamine, leading to histamine intoxication. In individuals with histamine intolerance (HIT) ingestion of food with normal contents of histamine causes histamine-mediated symptoms. HIT is a pathological process, in which the enzymatic activity of histamine-degrading enzymes is decreased or inhibited and they are insufficient to inactivate histamine from food and to prevent its passage to blood-stream. Diagnosis of HIT is difficult. Multi-faced, non-specific clinical symptoms provoked by certain kinds of foods, beverages and drugs are often attributed to different diseases, such as allergy and food intolerance, mastocytosis, psychosomatic diseases, anorexia nervosa or adverse drug reactions. Correct diagnosis of HIT followed by therapy based on histamine-free diet and supplementation of diamine oxidase can improve patient's quality of life.

Dropsy outbreak in a single family in Punjab, India.

Epidemic dropsy is caused by consumption of mustard oil contaminated with argemone oil. It usually occurs in outbreaks with acute manifestation of bilateral pitting edema, erythema, and local tenderness along with cardiac and respiratory problems in severe cases leading to death. We report an outbreak that is unusual because of its gradual onset, clustering in a single family, and with major manifestation of gastrointestinal illness mimicking acute gastroenteritis, hence leading to delayed diagnosis and high mortality. Thus, the diagnosis of epidemic dropsy should be considered as a strong possibility when there is clustering of cases in a single family with on and off gastrointestinal symptoms of vomiting and diarrhea in a mustard oil consuming belt.

Arsenic poisoning caused by intentional contamination of coffee at a church gathering--an epidemiological approach to a forensic investigation.

An outbreak of apparent food-borne illness following a church gathering was promptly reported to the Maine Bureau of Health. Gastrointestinal symptoms among church attendees were initially attributed to consumption of leftover sandwiches that had been served the previous day. However, a rapid epidemiological and laboratory assessment revealed the etiology of illness, including the death of an elderly gentleman, was not food-borne in origin. A criminal investigation determined that deliberate arsenic contamination of the brewed coffee by one of the church members was the source of the outbreak. Public health officials and criminal investigators must be aware that intentional biologic aggression can initially present as typical unintentional disease outbreaks. Practitioners must also consider the need to properly maintain and preserve potential forensic evidence. This case demonstrates the key role public health practitioners may play in criminal investigations.

Atrioventricular block induced by mad-honey intoxication: confirmation of diagnosis by pollen analysis.

An unusual type of food poisoning, mad-honey intoxication, can be observed in the Black Sea region of Turkey and various other parts of the world. It can occur after ingestion of grayanotoxin-contaminated honey produced from the nectar of Rhododendron ponticum and other plant species, chiefly of the Ericaceae and Sapindaceae families. Mad-honey intoxication can result in severe cardiac complications, such as complete atrioventricular block. The diagnosis is generally reached on the basis of the patient's history of honey intake. In this report, we describe the case of a patient who had mad-honey-related complete atrioventricular block; in this instance, the diagnosis was confirmed by a pollen analysis of the suspect honey.

Botulism from drinking pruno.

Foodborne botulism occurred among inmates at 2 prisons in California in 2004 and 2005. In the first outbreak, 4 inmates were hospitalized, 2 of whom required intubation. In the second event, 1 inmate required intubation. Pruno, an alcoholic drink made illicitly in prisons, was the novel vehicle for these cases.

Solanaceous steroidal glycoalkaloids and poisoning by Solanum torvum, the normally edible susumber berry.

Ingestion of immature, environmentally stressed, or cultivar-specific Solanum species (particularly the potato) has been previously associated with gastrointestinal and neurological symptoms caused by solanaceous steroidal glycoalkaloids (SGAs). We report on two geographically, temporally disparate outbreaks of poisoning by susumber berries (Solanum torvum- Solanaceae) and on detection of alkaloids not present in non-toxic berries. Five family members in New York City participated in a traditional evening meal containing Jamaican susumber berries. All those consuming berries were symptomatic the following morning with varying degrees of gastrointestinal distress, dizziness, slurred speech, cranial nerve deficits, and ataxia. The most seriously afflicted patient developed hypertension, confusion, proximal upper extremity weakness, and hypercapnic respiratory failure requiring prolonged mechanical ventilation. A separate cohort of six patients in Toronto ate unripe Jamaican susumber berries. They presented 14h post-ingestion with varying degrees of diarrhea, weakness, facial paralysis, slurred speech, ataxia, early hypertension, and proximal weakness. Two patients had ventilatory decompensation; one required intubation. Poisonous berries appeared indistinguishable from non-toxic varieties. We isolated solasonine, larger amounts of solamargine, and other steroidal glycoalkaloids in the toxic berry strains. S. torvum poisoning can produce significant neurological and gastrointestinal effects which appear to be mediated by SGAs present in the berries.

Anisakiasis digestiva. Aspectos de interés para el cirujano / Digestive anisakiasis. The surgical viewpoint

La anisakiasis digestiva es una enfermedad parasitaria que se adquiere tras la ingesta de pescado crudo o poco cocinado. Las manifestaciones clínicas son secundarias a la acción del Anisakis simplex sobre la pared del tubo digestivo. Se estima que esta enfermedad actualmente está infradiagnosticada, aunque cada vez es más frecuente la publicación de nuevos casos. La sintomatología es muy variable, en función del área del tubo digestivo donde asiente la larva. Puede simular diversos cuadros quirúrgicos, como obstrucción intestinal, apendicitis, peritonitis, ulcus y enfermedad de Crohn. El cirujano debe ser consciente de esta posibilidad e indagar los antecedentes de ingesta de pescado poco cocinado ante cualquier paciente con un cuadro abdominal agudo. Hay que tener en cuenta que esta posibilidad puede ahorrar muchas laparotomías innecesarias (AU)

[Botulism an a 38-year-old man after ingestion of garlic in chilli oil]. / Botulisme hos en 38-årig mand efter indtagelse af "hvidløg i chiliolie".

Botulism is a rare but potentially fatal disease caused by toxins produced by Clostridium botulinum. We report a case of botulism in a 38-year-old man after eating canned "garlic in chilli-oil". The patient was treated with antiserum. The diagnosis was confirmed by detection of botulinum B toxin by a bio-assay and growth of Clostridium botulinum from the food left-overs.
