RESUMO

Abstract The main aim of the paper is to assess whether vitamin C, vitamin D, and natural honey can be administered in the course of the COVID-19 pandemic for promising in line methods with recent evidence. Both systematic literature and clinical trial identification were conducted by searching various databases. A total 58 articles and 29 clinical trials were selected wherein 11 for vitamin C, 16 for vitamin D, and 2 for natural honey were identified for analysis. The high doses of vitamin C (i.e. '200 mg/kg body weight/day, divided into 4 doses') has been found to reduce COVID-19 lung damage, various flu infections. Additionally, the high doses of vitamin C can shorten around 7.8% stay in the intensive care unit. At the same time, vitamin D can effectively protect from lung injury and acute respiratory infections whereas vitamin D deficiency severely affects 75% of the institutionalized people (serum 25(OH) D < 25 nmol/L). Meanwhile, natural honey which contains proteins (0.1-0.4%); ash (0.2%); water (15-17%) has potential antiviral effects and the ability to improve immunity. Therefore, the administration of vitamins and honey is the promising evidence-based approach for reducing fatalities, saving lives, and bringing the COVID-19 pandemic to a rapid end. It is believed that the utilization of vitamin C, vitamin D, and natural honey with the current treatment may be effective in treating COVID-19-caused fatal complications such as pneumonia. Therefore, high-level clinical studies are required on COVID-19 to administrate the effects of vitamins and natural honey

RESUMO

An experiment was conducted to evaluate the potential of honey, propolis, and bee pollen for the reversal of lipid peroxidation induced by tebuconazole (TEB) in South American catfish (Rhamdia quelen), in which the concentration of thiobarbituric acid reactive substances (TBARS), the activity of the antioxidant enzyme glutathione-S-transferase (GST) and the concentrations of non-enzymatic antioxidants, reduced glutathione (GSH), ascorbic acid, and non-protein thiols were assessed. Honey (0.125 g L-1) and bee pollen (0.05 g L-1) added to the water reverse the production of TBARS induced by TEB, while propolis demonstrated a pro-oxidant effect, inducing an increase in TBARS production. The data presented herein suggest that the addition of water to honey and bee pollen potentially protects against the oxidative stress caused by agrichemicals.(AU)

RESUMO

INTRODUCCIÓN. Variadas investigaciones reconocen a la miel ventajas sobre fármacos de origen químico. Este trabajo persiguió como objetivo fundamental determinar la acción de la miel en el tratamiento de heridas sépticas. MÉTODOS. Se realizó un estudio descriptivo, observacional y comparativo sobre los efectos cicatrizantes de la miel, con un universo de 200 pacientes con heridas sépticas, que fueron atendidos en el Hospital Freyre Andrade y la Clínica Central Cira García entre los años 2000 y 2010. Se dividió aleatoriamente a los pacientes en dos grupos de 100 pacientes cada uno: un grupo control, a cuyos integrantes se les hizo una cura local diaria con solución salina al 0,9 por ciento, antisépticos y antibióticos locales; y un grupo de estudio, curado también localmente con solución salina al 0,9 por ciento pero con posterior aplicación de miel de abejas, en una capa que ocupó la herida en toda su profundidad y superficie. RESULTADOS. La mayoría de los cultivos realizados el primer día antes de curar la herida en el grupo control (98) continuaron siendo positivos (82) en el segundo cultivo (cuarto día), mientras que en el grupo de estudio solo fueron positivos 35 de los 95 cultivos realizados. En este grupo la fetidez y el tejido desvitalizado desaparecieron en las primeras 24 h de tratamiento, mientras que en el grupo control la situación se prolongó hasta el quinto y sexto días de tratamiento. El tejido de granulación útil apareció al segundo día en el grupo de estudio y en el octavo en el grupo control. En este último se documentaron 19 complicaciones asociadas al método de curación; no ocurrió así en el grupo de estudio, donde no hubo complicaciones ni reacciones adversas a la miel. CONCLUSIONES. La miel se puede utilizar para curar cualquier herida séptica, independientemente de su localización. Tiene fuertes propiedades desodorizantes, de limpieza y favorece la cicatrización de las heridas. En este estudio no se recogió ninguna complicación con su uso. Con este tipo de curación se ahorran 50,60 CUC por paciente(AU)


INTRODUCTION. Different researches recognize the advantages of honey on chemical drugs origin. The main objective of present paper was to determine the honey's action in the treatment of septic wounds. METHODS. A comparative, observational and descriptive study was conducted on honey healing effects including a universe of 200 patients with septic wounds, treated in the Freyre de Andrade hospital and the Cira García Central Clinic from 2000 to 2010 years. Patients were randomized into two groups of 100 patients each: a control group whose members undergo a daily local cure with 0,9 percent saline solution, local antiseptics and antibiotics, and other study group using the above mentioned technique but with a latter use of honey as a deep and superficial layer covering wound. RESULTS. Most of cultures made the first day before the wound's cure in the control group (98) remained positive (82) in the second culture (fourth day), whereas in the study group only 35 were positive from the 95 culture made. In this group the fetidness and the tissue devitalization disappeared during the first 24 hours of treatment, whereas in the control group this situation lasted until the fifth and sixth days of treatment. The useful granulation tissue appeared the second day in the study group and the eighth day in control group. In this latter there were 19 complications related to cure method but not in the study group in which there were neither complications nor adverse reactions to honey. CONCLUSIONS. The honey maybe used to cure any septic wound, regardless of its location. It has strong deodorizing and cleanliness properties favoring the wounds scarring. In present study there was not any complication related to its use. Using this type of healing it is possible to save 50.60 currencies by patient(AU)

RESUMO

Botulism is a rare disease in Chile and of the known clinical presentation, infant botulism is the most common. We report the case of a previously healthy seven month old male infant with a two weeks history of rinorrea, cough, fatigue, constipation and progressive weakness after the consumption of honey. Stool cultures were positive for Clostridium botulinum group 1 type A and electromyography was compatible with the diagnosis. The patient evolved with arterial hypertension, interpreted as secondary to autonomic dysfunction, which responded to calcium channel blockers. Muscle tone improved progressively during the following four weeks. Infant botulism is a potentially fatal disease; diagnosis can be difficult given the broad clinical manifestations. Prevention should focus on education of parents of infants as well as medical personnel.

El botulismo es un trastorno poco frecuente en nuestro país. De las formas conocidas, el botulismo infantil da cuenta de la mayoría de los casos. Comunicamos el caso clínico de un paciente de siete meses, sexo masculino, sin antecedentes mórbidos. Historia de dos semanas de coriza, tos y decaimiento. Tras la ingesta de miel presentó exacerbación de la sinto-matología respiratoria, constipación y debilidad muscular progresiva. Se analizó muestra de heces resultando positiva para Clostridium botulinum grupo I tipo A. El estudio electromiográñco fue compatible con el diagnóstico. Presentó hipertensión arterial, atribuyéndose a disfunción autonómica, con buena respuesta a bloqueadores de los canales de calcio. Recuperó progresivamente el tono muscular. En un control ambulatorio se apreciaba importante regresión de la sinto-matología. El botulismo infantil es una enfermedad potencialmente letal de no tratarse oportunamente y de difícil diagnóstico, ya que su presentación es similar a otros cuadros clínicos. Es necesario educar a padres y personal médico sobre las medidas de prevención para los lactantes bajo doce meses de edad.

RESUMO

O botulismo infantil tem afetado crianças abaixo de um ano de idade em várias regiões do mundo, e o mel tem sido identificado como uma das mais importantes fontes de intoxicação alimentar. Apesar disso, há dados escassos sobre o botulismo entre crianças no Brasil, especialmente no tipo de alimento comercial mais implicado nesta patologia. Este estudo pretendeu investigar a presença de esporos de Clostridium botulinum em mel comercializado no Brasil. Cem amostras de mel comercializado em seis diferentes Estados brasileiros (SP, MG, GO, CE, MT, SC) foram pesquisados para a presença de esporos de Clostridium botulinum, usando o choque térmico, seguido pela inoculação em caldo Cooked Meat Medium (Difco®) e incubado em condições anaeróbias. As culturas positivas foram analisadas através de esfregaços corados pelo Gram e semeadas em placas de Reinforced Clostrideo Agar (Difco®) e placas de Sulfito Polimixina Sulfadiazina -SPS (Difco®), as quais foram incubadas em condições anaeróbicas para obter colônias desta bactéria. As colônias positivas foram submetidas a teste de toxicidade através da inoculação em camundongos susceptíveis e caracterização bioquímica. Foram encontradas colônias de Clostridium botulinum que produzem toxinas ativas em 7 por cento das amostras de mel comercial, realçando a relevância deste microrganismo para a saúde pública devido ao alto risco potencial de o mel comercializado nestas regiões brasileiras causar o botulismo infantil, especialmente em crianças abaixo de um ano de idade.(AU)


Infant botulism has been affecting children under one year of age in several regions of the world and honey has been identified as one of the most important source of this food borne disease. Despite this, there are scarce data about botulism among children in Brazil, specially the type commercial food most implicated in this pathology. This study aimed at investigating the presence of spores of Clostridium botulinum in honey commercialized in Brazil. One hundred of honey samples commercialized in six different Brazilin states (SP, MG, GO, CE, MT, SC) were searched for the presence of spores of Clostridium botulinum, using thermal shock followed by the inoculation in Cooked Meat Medium (Difco®) and incubation in anaerobic conditions. The positives cultures were analyzed by Gram stain and seeded in Reinforced Clostrideo Agar (Difco®) and Sulfito Polimixina Sulfadiazina -SPS (Difco®) plates, which were incubated in anaerobic conditions in order to pick up the colonies of this bacteria. The positive colonies were submitted to toxicity test by inoculation in susceptible mice and to biochemical characterization. Clostridium botulinum colonies producing actively toxins were detected in 7 percent of the commercial honey samples, highlighting the relevance of this microorganism for public health due to the high potential risk of honey commercialized in these Brazilian regions to cause Infant Botulism, specially in children under one-year old.(AU)

RESUMO

Fifteen persons developed atropine poisoning following consumption of wasp honey. Clinical signs, antidotal response and the presence of Datura plants near the wasp nests supported that the intoxications were caused by ingestion of atropine-contaminated honey. Two deaths occurred from heatstroke because of the poisoning and high environment temperatures and intensive physical activity.

RESUMO

Infant botulism results from the in vivo production of toxin by Clostridium botulinum after it has colonized the infant's gut. Epidemiologic and laboratory investigations of this recently recognized disease were undertaken to identify risk factors and routes by which C. botulinum spores might reach susceptible infants. Clostridium botulinum organisms, but no preformed toxin, were identified in six different honey specimens fed to three California patients with infant botulism, as well as from 10% (9/90) of honey specimens studied. By food exposure history, honey was significantly associated with type B infant botulism (P = 0.005). In California, 29.2% (12/41) of hospitalized patients had been fed honey prior to onset of constipation; worldwide, honey exposure occurred in 34.7% (28/75) of hospitalized cases. Of all food items tested, only honey contained C. botulinum organisms. On household vacuum cleaner dust specimens and five soil specimens (three from case homes, two from control homes) contained Clostridium botulinum. The known ubiquitous distribution of C. botulinum implies that exposure to its spores is universal and that host factors contribute importantly to the pathogenesis of infant botulism. However, honey is now an identified and avoidable source of C. botulinum spores, and it therefore should not be fed to infants.
