ABSTRACT

A síndrome DRESS é uma entidade rara e distinta, caracterizada por acometimento cutâneo e envolvimento de órgãos internos, com risco potencial de morte. O diagnóstico e o tratamento pre- coces são de vital importância. Relatos de DRESS por paraceta- mol são raros na literatura, razão pela qual apresentamos este caso. Paciente do sexo masculino, 56 anos, com surgimento de rash maculopapular, febre, linfadenopatia e hipereosinofilia 3 semanas após suspensão de paracetamol, associados ao ante- cedente familiar de reação a fármaco. Evoluiu bem após pulso- terapia com metilprednisolona.


DRESS syndrome is a rare and distinct entity characterized by cutaneous manifestations and internal organs involvement with a potential risk of death. Early diagnosis and treatment are vi- tally important. Reported cases of DRESS syndrome due to ace- taminophen are rare in the literature, and that is the reason for this case report. A 56-year-old male patient with maculopapular rash, fever, lymphadenopathy, and hypereosinophilia three we- eks after suspension of acetaminophen, associated with a family history of drug reaction. It progressed well after pulse therapy with methylprednisolone.

ABSTRACT

As an effective antipyretic medicine,Indigo Naturalis has a long history of application in the field of Chinese medicine.The content of organics,mainly indigo and indirubin,is about 10%. However,the active ingredients and mechanism of its antipyretic effect have not yet been fully elucidated. In view of this,they were investigated in this study with the rectal temperature change as an indicator and 2,4-dinitrophenol-induced fever rats as subjects. The content of PGE2 and c AMP in the hypothalamus and the serum levels of TNF-α,IL-1β and IL-6 were determined by ELISA. Moreover,the plasma samples of fever rats were analyzed by metabonomics in combination with UPLC-Q-TOF-MS for the exploration of potential biomarkers and the discussion on the antipyretic mechanism of Indigo Naturalis and its active ingredients. The results showed that the rising trend of rectal temperature in rats was suppressed 0. 5 h after the treatment with Indigo Naturalis,organic matter,indigo or indirubin as compared with the rats of model group( P < 0. 05),among which Indigo Naturalis and organic matter had better antipyretic effect. ELISA results showed that organic matter and indigo can inhibit the expression of PGE2 and c AMP( P<0. 01),while Indigo Naturalis and organic matter were effective in curbing the increase in TNF-α( P<0. 05). A total of 21 endogenous metabolites were identified from the plasma samples of the Indigo Naturalis,organic matter,indigo and indirubin groups,which were mainly involved in glycerophospholipid metabolism.

ABSTRACT

COVID-19 afecta entre el 1.2 al 5% de niños y adolescentes en diversos países incluyendo Guatemala, la mayoría con manifestaciones clínicas leves a moderadas. La terapéutica farmacológica para enfermedad grave aún no está completamente establecida, por lo que se realizó una revisión de literatura de artículos científicos publicados en revistas indizadas para proporcionar una actualización del tratamiento de COVID-19 en niños y adolescentes, que ayude a orientar las decisiones clínicas. El tratamiento de casos leves consiste en antipiréticos, antibióticos en neumonía leve; en casos moderados, monitoreo de signos vitales, cánula binasal, manejo de líquidos, antipiréticos y analgésicos, toma de hemocultivo, inicio de antibióticos y uso de beta agonistas de acción corta o esteroides inhalados. En enfermedad grave, ventilación mecánica no invasiva o invasiva, ventilación prono temprana, soporte nutricional, hídrico y vasopresor, mantenimiento del equilibrio ácido base y de electrolitos. Se indica el uso de antibióticos y antivirales como remdesivir y el manejo inmunológico con interferón alfa, esteroides y/o inmunoglobulina. Se monitorea función hepática, renal, inmunológica, hematológica y cardíaca. No se ha encontrado evidencia de que la hidroxicloroquina, ivermectina y algunos antivirales disminuyan la mortalidad en pacientes pediátricos. Actualmente no existe ningún medicamento específico, validado científicamente para el tratamiento de COVID-19 en niños. El tratamiento para casos graves se decide a partir de las experiencias del tratamiento en adultos, por lo cual es importante continuar con investigación de fármacos específicos para la población pediátrica.


COVID-19 affects among 1.2 to 5% of children and adolescents in various countries, counting Guatemala, the most with mild to moderate clinical manifestations. Pharmacological therapy for severe disease has not yet been fully established. A literature review of scientific articles from indexed journals was conducted to provide an update on the treatment of COVID-19 in children and adolescents, to help guide clinical decisions. Treatment of mild cases consists of antipyretics and antibiotics for pneumonia. In moderate cases is recommended to monitor vital signs, to obtain blood cultures and to treat with binasal cannula, fluids, antipyretics and analgesics, short-acting beta agonists and/or inhaled steroids and antibiotics when needed. In severe illness, treatment includes non-invasive or invasive mechanical ventilation, early prone ventilation, nutritional, hydration and vasopressor support, maintenance of acid-base, and electrolyte balance. The use of antibiotics and antivirals as remdesivir is recommended, as well as the use of immunomodulators such as interferon alfa, steroids and/or immunoglobulin. To monitor patient´s evolution; liver, kidney, immunological, hematological, and cardiac function must be assessed. No evidence has been found that hydroxychloroquine, ivermectin and other antivirals decrease mortality in pediatric patients. Currently, there is no specific, scientifically validated medication for the treatment of COVID-19 in children. Treatment for severe cases is decided based on management experiences in adults, so it is important to doing research on specific drugs for the pediatric population.

ABSTRACT

En el transcurso de la pandemia de COVID-19, numerosos países, de ingresos bajos, medianos y alto, han visto agotadas sus reservas de medicamentos esenciales necesarios para el manejo de los pacientes con COVID-19 en las unidades de cuidados intensivos (UCI). El plan de preparación para emergencias sanitarias de los países requiere incluir una lista de medicamentos esenciales y otros dispositivos médicos necesarios en las UCI para afrontar emergencias sanitarias. La lista de medicamentos esenciales para el manejo de pacientes que ingresan a unidades de cuidados intensivos con sospecha o diagnóstico confirmado de COVID-19 es un documento de orientación fundamental que ayuda a los sistemas de salud de los países a priorizar los medicamentos esenciales que deben estar ampliamente disponibles y ser asequibles para manejar los pacientes en las UCI durante las situaciones de emergencia sanitaria, en este caso con sospecha o diagnóstico confirmado de COVID-19. Está dirigida a las autoridades sanitaras y a los encargados del manejo del sistema de salud de los países. Esta lista incluye fundamentalmente los medicamentos considerados esenciales para el manejo de los cuadros clínicos que con se observan con mayor frecuencia en pacientes hospitalizados en UCI a causa de una infección por SARS-CoV-2. No se incluyen la mayoría de los medicamentos que comúnmente se encuentran en las UCI para el manejo de otras patologías, comorbilidades o la estabilización del paciente (p. ej., insulina o antihipertensivos), salvo aquellos que pueden requerirse para el tratamiento o apoyo (p. ej., bloqueantes neuromusculares o anestésicos) de las dolencias generadas por la infección. Tampoco se incluyen medicamentos específicos para el tratamiento de la infección por SARS-CoV-2, puesto que no existe, por el momento, evidencia científica de alta calidad que avale su uso, salvo en el contexto de ensayos clínicos controlados. Un equipo de expertos en el tema realizó una búsqueda de información sobre la atención de pacientes en UCI durante la pandemia de COVID-19, en Medline (a través de PubMed), Cochrane, Tripdatabase, Epistemonikos y en buscadores generales de internet (Google). Se identificaron también revisiones o guías generadas por ministerios de Salud de varios países de la Región de las Américas, la Organización Mundial de la Salud (OMS), la Organización Panamericana de la Salud (OPS), el Instituto Nacional de Salud y Excelencia Clínica (NICE) de Reino Unido, los Centros para el Control y la Prevención de Enfermedades (CDC) de Estados Unidos y los Institutos Nacionales de Salud (NIH) de Estados Unidos.

ABSTRACT

Introducción. La fiebre en pediatría es motivo de consulta frecuente. El objetivo fue evaluar los conocimientos, actitudes y temores de los padres ante la fiebre de sus hijos.Material y métodos. Estudio observacional, analítico, transversal. En 2018, se realizó una encuesta a padres de niños de entre 6 meses y 5 años que asistieron al Hospital de Niños Ricardo Gutiérrez de la Ciudad de Buenos Aires.Se analizó la asociación entre las variables sociodemográficas y los conocimientos, actitudes y temores frente al cuadro febril.Resultados. Se realizaron 201 encuestas. El 56,7 % de los padres consideró que la fiebre era mala para la salud. El 37 % definió fiebre entre 37 °C y 37,5 °C, y el 59 %, 38-38,5 ºC. La media de temperatura considerada grave fue 39,2 °C (desvío estándar 0,69). El 93 % de los cuidadores utilizaba medidas físicas; el 97 % administraba antitérmicos y el 14,5 % los alternaba. Los temores a las consecuencias fueron, en el 82 %, convulsiones; en el 41 %, deshidratación; en el 18 %, daño cerebral y, en el 12 %, muerte. El 86,5 % despertaba a sus hijos para administrarles antitérmico. En el estrato de mayor instrucción materna, fue menor el temor a la fiebre (odds ratio0,5; intervalo de confianza del 95 %: 0,28-0,91).Conclusiones. Un tercio de los encuestados consideró fiebre valores bajos de temperatura. El temor a la fiebre fue elevado y el nivel de instrucción materna podría mitigarlo.


Introduction. In pediatrics, fever is a common reason for consultation. The objective was to assess parental knowledge, behaviors, and fears in the management of fever in their children.Materials and methods. Observational, analytical, cross-sectional study. In 2018, a survey was administered to the parents of children aged 6 months to 5 years who attended Hospital de Niños Ricardo Gutiérrez, in the Autonomous City of Buenos Aires. The association between sociodemographic outcome measures and knowledge, behaviors, and fears in cases of fever was analyzed.Results. A total of 201 surveys were completed: 56.7 % of parents considered that fever was bad for health; 37 % defined fever between 37 °C and 37.5 °C, and 59 %, between 38 °C and 38.5 °C. The mean temperature considered severe was 39.2 °C (standard deviation: 0.69). Physical methods were used by 93 % of caregivers; 97 % administered antipyretic agents, and 14.5 % used alternating agents. Fears of consequences included seizures in 82 %, dehydration in 41 %, brain damage in 18 %, and death in 12 %. Also, 86.5 % woke up their children to give them an antipyretic agent. Among the higher maternal education level, fear of fever was lower (odds ratio: 0.5; 95 % confidence interval: 0.28-0.91).Conclusions. One-third of survey respondents considered low body temperature values as fever. Fear of fever was high, and the level of maternal education may mitigate it.

ABSTRACT

PURPOSE: Data are lacking on the association between the allergic rhinitis (AR) phenotype and sensitization to specific allergens or bronchial hyperresponsiveness (BHR) in children. We here investigated risk factors and comorbidities, including sensitization to specific allergens and BHR, for the AR phenotype by AR and its Impact on Asthma (ARIA) classification in a general population-based birth cohort study. METHODS: We enrolled 606 children aged 7 years from the Panel Study of Korean Children. The AR phenotype was assigned in accordance with the ARIA classification in children. Skin prick tests and Provocholine provocation test were performed. Risk factors and comorbidities for AR phenotypes were then analyzed. RESULTS: The prevalence of mild and moderate to severe AR in our study cohort was 37.2% and 8.8%, respectively. Recent use of analgesics or antipyretics and current cat ownership were associated with the risk of mild persistent AR. Sensitizations to Dermatophagoides Pteronyssinus (Der p), Japanese hop and cat were associated with moderate to severe persistent AR. Children with moderate to severe AR had a higher risk of current asthma and BHR compared to mild AR cases (adjusted odds ratio [aOR], 5.26; 95% confidence interval [CI], 1.77–15.62). Moderate to severe AR with allergic sensitization was associated with the highest risk of BHR (aOR, 11.77; 95% CI, 3.40–40.74). CONCLUSIONS: Moderate to severe-persistent AR is more closely related to respiratory comorbidities and sensitizations than mild AR. Stratifying the AR phenotype by ARIA classification may assist in disease management.

ABSTRACT

Resumen La fiebre es un signo frecuente en el niño críticamente enfermo durante su estadía en la unidad de cuidados intensivos, y debe ser entendida como una respuesta biológica evolutiva, de carácter adaptativo normal del huésped al estrés fisiológico. Es el resultado de una compleja respuesta a estímulos pirogénicos, resultando en la generación de citocinas y prostaglandinas. Los mecanismos moleculares implicados en el inicio de la fiebre aún no están totalmente precisados, originando dificultades en el conocimiento de los procesos fisiopatológicos exactos involucrados y, por ende, necesarios para elaborar una adecuada y específica estrategia terapéutica. Estudios experimentales concluyen que la fiebre y la inflamación son benéficas para el huésped; no obstante, la terapia antipirética es comúnmente empleada y estudios en humanos sobre la presencia de fiebre y su tratamiento para el pronóstico del paciente crítico con sepsis no son concluyentes. Para el médico intensivista es esencial disponer de información actualizada referente a la fisiología de la termorregulación humana, el efecto de la temperatura en rango febril sobre múltiples procesos biológicos involucrados en la defensa del huésped y las intervenciones termorreguladoras en el paciente con sepsis.


Abstract Fever is a very common sign to observe in critically ill children during their intensive care unit stay. This should be understood as an evolutionary biological response, of normal adaptive character, from the host to the physiological stress. It is the result of a complex response to pyrogenic stimuli, resulting in the generation of cytokines and prostaglandins. The molecular mechanisms involved in the onset of fever are not yet fully specified, thus creating difficulties in the knowledge of the exact pathophysiological processes involved and, therefore, necessary to elaborate an adequate and specific therapeutic strategy. Experimental studies conclude that fever and inflammation are beneficial to the host. However, antipyretic therapy is commonly employed and human studies on the presence of fever and its treatment for the prognosis of critically ill septic patients are inconclusive. Up-to-date information on the physiology of human thermoregulation, the effect of temperature on febrile range over multiple biological processes involved in host defense, and thermoregulatory interventions in the septic patient are essential to know by the critical care physician.

ABSTRACT

PURPOSE: To investigate caregivers' preference regarding fever management in the emergency department. METHODS: Between July 2011 and June 2014, we surveyed the preference in fever management by caregivers of febrile children aged 7 years or younger who visited the emergency department. The questionnaire consisted of the characteristics of the children and their caregivers, usefulness of tepid massage, and the caregivers' preference in fever management, in particular the combination of methods and the doses of antipyretics. RESULTS: Among a total of 161 children, 161 were enrolled in the study, with the mean age of 5.0 years. Of the caregivers, 64.6% were in their 30s and 50.9% were parents, and 70.2% and 24.2% reported that tepid massage was "very useful" and "a little useful," respectively. The most preferred combination of methods was "tepid massage, acetaminophen, and ibuprofen (50.9%; P < 0.001)." "Tepid massage and ibuprofen" was preferred to "tepid massage and acetaminophen (24.2% vs 7.5%)." The most preferred dose of antipyretics was 1 mL/kg/day (divided into 3 doses; 60.2%; P = 0.012), followed by 1 mL/kg/day (divided into 3 doses) plus 2 mL/dose (29.1%). CONCLUSION: Caregivers may recognize tepid massage as a useful fever management. The most preferred fever management was the combination of tepid massage, acetaminophen, and ibuprofen with a dose of 1 mL/kg/day.

ABSTRACT

Pyrimidine derivative 3 was afforded through the reaction of compound (1) with 5-ureidohydantion (2). Product 3 underwent a cyclization to produce fused pyrimidine derivative 7, although the latter product 7 was synthesized through one step via the reaction of compound (1) with 5-ureidohydantion (2) using another catalyst. Compound 3 was oriented to react with cyclic ketones 8a,b in the presence of elemental sulfur, salicylaldehyde (10), aryldiazonium chlorides 12a,b and ω-bromo-4-methoxy- acetophenone (14), which afforded, fused thiophene derivatives 9a,b, coumarin derivative 11, arylhdrazono derivatives 13a,b and 4-methoxyphenyl butenyl derivative 15, respectively. The latter product 15 was reacted with either potassium cyanide (16a) or potassium thiocyanide (16b) to form cyano and thiocyano derivatives 17a,b, respectively. Compound 17a underwent further cyclization to afford pyridopyrimidine derivative 19. Compound 15 was reacted with either hydrazine (20a) or phenylhydrazine (20b) to produce hydrazo derivatives 21a,b and these products were cyclize to produce pyrrole derivatives 23a,b. Finally, 5-ureidohydantion (2) was reacted with compounds 24a,b,c to afford pyrimidine derivatives 25a,b,c. The structures of the synthesized compounds were confirmed using IR, 1H NMR, 13C NMR and mass spectrometry techniques. Compounds 11 and 19 have promising as analgesic and antipyretic activities

ABSTRACT

Species of the genus Tabebuia are used in traditional medicine and are reported in the literature for their properties against various diseases. The objective of this study was to evaluate the antipyretic, sedative and hypnotic activities of methanol extract of Tabebuia hypoleuca stems (THME) using the Brewer's yeast induced pyrexia, Open field and Sodium thiopental-induced sleeping time tests, respectively. In the Brewer's yeast induced pyrexia test, THME at 500 mg/kg produced a significant (p<0.001) decrease of the fever as from the first hour after administration and was sustained for 4 h. In the Open-field test, THME did not cause any significant change in the number of crossings, rearing, preening and defecation, and either in the time of immobility. Moreover, THME did not produce changes in neither the sleeping latency nor the sleeping time induced by sodium thiopental. These results showed that THME administered orally at 500 mg/kg exerts antipyretic activity, probably mediated by the inhibition of the enzyme cyclooxygenase-2. This study also showed that THME does not exert sedative and hypnotic effects at the doses tested.


Especies del género Tabebuia se utilizan en la medicina tradicional y se reportan en la literatura por sus propiedades contra diversas enfermedades. El objetivo de este estudio fue evaluar la actividad antipirética, sedante e hipnótica del extracto metanólico de los tallos de Tabebuia hypoleuca (THME) utilizando las pruebas de pirexia inducida por levadura de cerveza, campo abierto y tiempo de sueño inducido por tiopental sódico respectivamente. En el ensayo de pirexia inducida por levadura de cerveza, THME a 500 mg/kg produjo una reducción significativa (p<0.001) de la fiebre a partir de la primera hora después de la administración y se mantuvo durante cuatro horas. En el ensayo de campo abierto, THME no causó ningún cambio significativo en el número de cruces, levantamientos, acicalamientos y defecación, ni en el tiempo de inmovilidad. Además, THME no produjo cambios ni en la latencia de sueño, ni en el tiempo de sueño inducido por tiopental sódico. Estos resultados mostraron que THME administrado oralmente en dosis de 500 mg/kg posee actividad antipirética, mediado probablemente a la inhibición de la enzima ciclooxigenasa-2. Este estudio también demostró que THME no posee actividad sedante e hipnótica en las dosis ensayadas.

ABSTRACT

The antipyretic effect of the aqueous extract of herbal coded formulation containing equal amount of Salix alba, Emblica officinalis, Glycyrrhiza glabra, Adhatoda vasica, Viola odorata, Thea sinensis, Veleriana officinalis, Foeniculum vulgare, Sisymbrium irrio and Achillea millefolium was investigated using the yeast induced pyrexia model in rabbits. Paracetamol was used as a control group. Rectal temperatures of all rabbits were recorded immediately before the administration of the extract or paracetamol and again at 1 hour, after this, temperature was noted at 1 hrs interval for 5 hrs using digital thermometer. At 240 mg/kg dose the extract showed significant reduction in yeast-induced elevated temperature as compared with that of standard drug paracetamol [150 mg/kg]. It is concluded that herbal coded medicine at a dose of 240 mg/kg has marked antipyretic activity in animal models and this strongly supports the ethno pharmacological uses of medicinal plants of this formulation

ABSTRACT

To investigate the antipyretic activity of hydro-methanol extract of Melia azedarach Linn. [HMEMA] seeds and Cucumis melo Linn. [HMECM] seeds in experimental animals. Baker's yeast was used to induce fever in rabbits which were divided into six groups. The animal groups were thereafter administered distilled water [control], paracetamol [reference standard, 150mg/kg], HMEMA [250mg/kg], HMEMA [500mg/kg], HMECM [250mg/kg] and HMECM [500mg/kg] respectively. HMEMA and HMECM were also phytochemically screened for tannins, alkaloids, phenols, flavonoids, saponins and cardiac glycosides. Results indicate that hydro-methanol extract of M. azedarach Linn. Seeds [250mg/kg and 500mg/kg] significantly [p<0.001, p<0.05 respectively] reduced the elevated body temperature in dose dependant manner. Insignificant to no antipyretic effect was produced by hydro-methanol extract of Cucumis melo L. seeds. Phytochemical analysis of the HMEMA showed the presence of flavonoids, saponins, tannins, phenols, alkaloids and cardiac glycosides While HMECM was positive for flavonoids, phenols and saponins. The result shows that there exists a potential benefit in utilizing Melia azedarach L. seeds in treating fever. This property can be attributed to the presence of phytochemical constituents present in the hydro-methanol extract ofMelia azedarach L. seeds and the exact mechanism need to be evaluated

ABSTRACT

OBJETIVO: Determinar el conocimiento sobre la fiebre, de los padres de niños menores de 5 años que acuden al servicio de Emergencias del Hospital de Niño DISEÑO: descriptivo prospectivo de serie de casos. LUGAR: El estudio se realizó entre octubre de 2016 y noviembre de 2016 en el Servicio de Emergencias del Hospital del Niño "Ovidio Aliaga Uría" de la ciudad de La Paz. PARTICIPANTES: padres de niños febriles que acudieron al Hospital del Niño "Ovidio Aliaga Uría" de 0 a 59 meses de edad MEDICIONES PRINCIPALES: el instrumento evaluó la escolaridad de los padres, el punto de corte considerado como fiebre, las consecuencias temidas de la fiebre, la droga usada para la fiebre, la dosis administrada en caso de usarse algún medicamento, la fuente de información de donde se obtuvo el conocimiento de fiebre, si se sabe medir la temperatura, cual es el método más usado para la medición de temperatura y cuáles son los tratamientos alternativos que se utilizan. RESULTADOS. El intervalo de alza térmica que los padres consideran como una fiebre es entre 37 a 37,5°C (52%). El temor de los padres es que la temperatura incremente por más de 39°C con un porcentaje de 59%. El principal temor de los padres frente a un alza térmica es que desencadene convulsiones 46%. El medicamento más utilizado es el paracetamol 53%, las dosis administradas por los padres de antitérmicos son dosis inadecuadas en 50% de los casos. Saben medir la fiebre 64% siendo el principal instrumento utilizado el termómetro oral (36%). CONCLUSIONES. Una gran parte de los padres manejan un concepto errado respecto al punto de corte para considerar fiebre. El principal temor de los padres ante el ascenso de la misma es la presencia de convulsiones. La droga más usada por los padres que participaron en nuestro estudio es el paracetamol. La principal fuente de información de los padres era la información brindada por personal de salud, pero existe una tendencia a usar sobredosis de antitérmicos. Aún son usados métodos caseros y naturales para controlar la fiebre.


OBJECTIVE: To determine knowledge about fever in parents of young children attending to emergency department. DESIGN: Descriptive and prospective study from case series. PLACE: The study was conducted from October to November 2016 in emergency department at Dr. Ovidio Aliaga Uría Children Hospital. PARTICIPANTS: Parents of young children from 0 to 59 months old that showed febrile seizures at attending emergency room in the hospital. MAIN MEASURES: Survey considered parents knowledge about the cut off to consider fever, feared consequences of fever, used drugs to treat, drug doses in case of administrating medicaments, source of information regarding knowledge about fever, how to measure children temperature, the methods to measure temperature and the alternative treatments about fever. RESULTS: Parents considered fever when temperature rises between 37 to 37,5 °C (52%). Parents get afraid when temperature increases higher than 39 °C, in a 59%. The presence of seizures is the main fear in parents (46%). paracetamol is most used drug. 50%the cases displayed an inadequate dose administration of antipyretic. CONCLUSIONS: most of the parents have an inadequate concept about the cut of to consider fever. The mean fear is the presence of fever seizures, paracetamol is the most used drug. The source information of parents is obtained from health staff, but they tend to overdose the administration of antipyretics, and the use of home methods is still common.

ABSTRACT

PURPOSE: Glehnia littoralis has been used to treat ischemic stroke, phlegm, cough, systemic paralysis, antipyretics and neuralgia. The pharmacological mechanisms of Glehnia littoralis include calcium channel block, coumarin derivatives, anticoagulation, anti-convulsive effect, as well as anti-oxidant and anti-inflammatory effects. Alpha-amanitin (α-amanitin) is a major toxin from extremely poisonous Amanita fungi. Oxidative stress, which may contribute to severe hepatotoxicity was induced by α-amanitin. The aim of this study was to investigate whether Glehnia littoralis ethyl acetate extract (GLEA) has the protective antioxidant effects on α-amanitin -induced hepatotoxicity. METHODS: Human hepatoma cell line HepG2 cells were pretreated in the presence or absence of GLEA (50, 100 and 200µg/ml) for 4 hours, then exposed to 60µmol/L of α-amanitin for an additional 4 hours. Cell viability was evaluated using the MTT method. AST, ALT, and LDH production in a culture medium and intracellular MDA, GSH, and SOD levels were determined. RESULTS: GLEA (50, 100 and 200µg/ml) significantly increased the relative cell viability by 7.11, 9.87, and 14.39%, respectively, and reduced the level of ALT by 10.39%, 34.27%, and 52.14%, AST by 9.89%, 15.16%, and 32.84%, as well as LDH by 15.86%, 22.98%, and 24.32% in culture medium, respectively. GLEA could also remarkably decrease the level of MDA and increase the content of GSH and SOD in the HepG2 cells. CONCLUSION: In the in vitro model, Glehnia littoralis was effective in limiting hepatic injury after α-amanitin poisoning. Its antioxidant effect is attenuated by antidotal therapy.

ABSTRACT

La hiperostosis cortical infantil, o enfermedad de Caffey-Silverman, es una entidad clínica caracterizada por neoformación ósea perióstica secundaria a un proceso inflamatorio agudo. De baja frecuencia, su curso clínico es generalmente autolimitado y de excelente pronóstico. Objetivo: Presentar el caso de un lactante portador de un cuadro clínico compatible con una hiperostosis cortical infantil. Caso clínico: Lactante varón, 4 meses de edad, previamente sano, que consultó por presentar irritabilidad, llanto, aumento de volumen en la cara, los brazos y las piernas. Se observó aumento de volumen al nivel de la rama mandibular bilateral, simétrica, sensible, sin cambios en la coloración, la temperatura o la textura, hasta la región preauricular. El estudio bioquímico fue normal, y el estudio radiológico mostró reacción perióstica (periostitis e hiperostosis) al nivel de la rama mandibular, el fémur izquierdo, la tibia y el radio bilateral. Se manejó con antipiréticos, antiinflamatorios y analgésicos, y estuvo en observación en el servicio de urgencias durante 6 h, donde se decidió su egreso y el manejo ambulatorio. La sintomatología cedió por completo entre 4 y 6 semanas después del alta. Conclusión: La hiperostosis cortical es una colagenopatía que debe ser considerada como diagnóstico diferencial en cuadros agudos de inflamación ósea, irritabilidad y fiebre. Es indispensable conocerla para sospecharla y la correlación clínico-radiológica es notable.


Infantile Cortical Hyperostosis, or Caffey-Silverman disease, is a rare condition characterised by generalised bone proliferation mediated by an acute inflammatory process. Diagnosis can be made through clinical evaluation and X-ray studies. The course is generally self-limiting and prognosis is excellent. Objective: To present the case of a 4-month child with clinical and radiological symptoms compatible with Infantile Cortical Hyperostosis. Case report: A 4-month old male who presented with crying and irritability associated with swelling of the face, arms and legs was admitted to the Emergency Room of National Institute of Pediatrics. Bilateral mandibular swelling extending to periauricular region was observed, with no signs of inflammation. X-ray studies showed a periosteal reaction in the jaw, left femur and tibia, and radius bilateral. Clinical observation combined with analgesics and antipyretics was the only medical intervention. Four to six months after discharge from hospital, the symptoms disappeared, confirming the good prognosis of this condition. Conclusion: Infantile cortical hyperostosis is a collagenopathy, which must be considered as a differential diagnosis in acute bone inflammatory processes, irritability and fever. It is important to understand and identify this disease and clinical-radiological correlation is remarkable.

ABSTRACT

Abstract The objective of this study was to evaluate the action of Hymenaea stigonocarpa bark hydroalcoholic extract against a mutagenic compound using A. cepa meristematic root cells as a test system. The treatment groups were: Negative Control (NC) – distilled water; Positive Control (PC) – paracetamol at a concentration of 0.008 mg/mL, Jatoba Control (JC) – aqueous fraction jatobá-do-cerrado at 0.5 or 1.0 or 1.5 mg/mL, and Simultaneous Treatment (ST) - jatobá-do-cerrado aqueous fraction at a concentration of 0.5 or 1.0 or 1.5 mg/mL associated with paracetamol solution at a concentration of 0.008 mg/mL. All groups were analyzed at 24 and 48 h. Five onion bulbs (five replications) were used for each treatment group. The root tips were fixed in Carnoy and slides prepared by the crush technique. Cells were analyzed throughout the cell cycle, totaling 5,000 for each treatment group at each exposure time. Mitotic indices were subjected to statistical analysis using the chi-square test (p<0.05). From the results it was found that the ST group, at the three concentrations, significantly potentiated the antiproliferative effect of the test system cells when compared to PC, NC and TJ at the three concentrations. Furthermore, the three ST concentrations significantly reduced the number of cell aberrations when compared to the number of aberrant cells obtained for the PC, demonstrating antimutagenic action on the A. cepa test system cells.


Resumo O objetivo do presente trabalho foi avaliar a ação do extrato hidroalcólico do ritidoma de Hymenaea stigonocarpa frente a um composto mutagênico, utilizando como sistema teste as células meristemáticas de raízes de A. cepa. Os grupos tratamentos avaliados foram: Controle Negativo (CN) – água destilada; Controle Positivo (CP) – paracetamol na concentração de 0,008 mg/mL, Controle Jatobá (CJ) – fração aquosa de jatobá-do-cerrado na concentração de 0,5 ou 1,0 ou 1,5 mg/mL, e Tratamento Simultâneo (TS) – fração aquosa de jatobá-do-cerrado na concentração de 0,5 ou 1,0 ou 1,5 mg/mL associada a solução de paracetamol na concentração de 0,008 mg/mL. Todos os grupos foram analisados nos tempos de 24 e 48 h. Para cada grupo tratamento cinco bulbos de cebolas (cinco repetições) foram utilizados. As radículas foram fixadas em Carnoy e as lâminas preparadas pela técnica de esmagamento. Analisaram-se células em todo ciclo celular, totalizando 5.000 para cada grupo tratamento em cada tempo de exposição. Os índices mitóticos obtidos foram submetidos à análise estatística do Qui-quadrado (p<0,05). A partir dos resultados verificou-se que o grupo TS, nas três concentrações, potencializou o efeito antiproliferativo significativo as células do sistema teste quando comparado ao CP, CN e TJ nas três concentrações. Ainda, o TS nas três concentrações reduziu de forma significativa o número de aberrações celulares quando comparado com o número de células aberrantes obtidas para o CP, demonstrando ação antimutagênica as células do sistema teste A. cepa.
