Full Text Available Audience: This simulation session is appropriate for medical students, community physicians, or residents in emergency medicine, neurology, pediatrics, or family medicine. Introduction: Febrile seizures are the most common form of seizures in childhood; they are thought to occur in 2-5% of all children.1-3 Febrile seizures are defined as a seizure in association with a febrile illness in children without a central nervous system infection, previous afebrile seizure, known brain disorder, or electrolyte abnormalities. 1,2 They typically occur between 6 months and 18 months of age though they can occur up to 5 years of age.3 Febrile seizures are categorized as: simple (generalized seizure lasting less than 15 minutes in a child aged 6 months to 5 years, and less than 1 in a 24 hour period or complex (a focal seizure or generalized seizure lasting greater than 15 minutes, or multiple seizures in a 24 hour period. 1,3 Treatment for febrile seizures is based on treating the underlying cause of the fever and giving reassurance and education to the parents.2 Mortality is extremely rare, and there is no difference in the patient’s cognitive abilities after a febrile seizure, even when the seizure is prolonged.1 Objectives: At the end of this simulation session, the learner will be able to: 1 discuss the management of febrile seizures 2 discuss when placement of an advanced airway is indicated in the management of a febrile seizure 3 list the risk factors for febrile seizures 4 prepare a differential diagnosis for the causes of febrile seizures 5 educate family members on febrile seizures. Methods: This educational session is a high-fidelity simulation.

Full Text Available Diferentes investigadores han realizado estudios sobre el manejo del niño febril y plantean que es un dilema al que se enfrenta a diario el médico que atiende niños. Motivados por este tema se efectuó un estudio descriptivo retrospectivo de los niños febriles, sin causa aparente en su valoración inicial, que asistieron al servicio de urgencias en un período de 9 meses, con el objetivo de identificar el diagnóstico definitivo al egreso y se precisó el tipo de infección bacteriana severa y relacionó la presencia de éstos con parámetros clínicos y de laboratorios. El mayor número de niños febriles valorados e ingresados mostraron edades desde 91 días hasta 36 meses. El menor porcenaje de ellos ingresaron y desarrollaron alguna infección bacteriana severa principalmente neumonía, y fue mayor el porcentaje de niños con esta patología a menos edad con predominio del aspecto tóxico y de la temperatura 39 EC. Resultó el manejo ambulatorio del niño febril mayor de 90 días y bajo riesgo de infección bacteriana severa un ahorro en vidas y dinero, por lo que se recomienda generalizar el flujograma propuesto para la evaluación y manejo del niño febril de 3 a 36 meses de edad.Different researches have performed studies on the management of the febrile infant and they point out that this is a dilemma faced by every physician who takes care of children. Motivated by this subject, a descriptive and retrospective study of febrile infants was conducted. The study was carried out to evaluate febrile infants without evident cause at the baseline evaluation who attended the emergency service during a period of 9 months with the objective of identifying the definite diagnosis at admission. The type of bacterial infection was accurately assessed and the presence of this was related to clinical and laboratory parameters. The greatest number of febrile infants evaluated and admitted to hospital were 91 days-36 months old. The lowest percentage

Full Text Available Antecedentes y Objetivos. La contractura capsular (CC es la complicación más común y frustrante en mujeres que se han sometido a cirugía de aumento mamario con fines estéticos. La causa es actualmente desconocida y se considera que a menudo participan varios factores conjuntamente. Material y Método. Realizamos un estudio prospectivo observacional de casos y controles anidados en una cohorte de pacientes y llevado a cabo durante 4 años en la Clínica Ruber de Madrid. Resultados. Determinamos que el ejercicio físico es un factor de riesgo en el desarrollo de CC, con una probabilidad 5 veces mayor de desarrollo en pacientes que lo realizan respecto a las que no lo practican; sobre todo los ejercicios relacionados con la movilidad de los miembros superiores, entre ellos los aeróbicos suaves, la natación y la musculación. El ejercicio físico actuaría como principal causa de fricción entre cápsula e implante rugoso, y llegado un momento, dicha fricción originaría pequeñas roturas en la cápsula periprotésica generando una respuesta inflamatoria. El brazo hábil dominante resultó ser un factor de riesgo en el desarrollo de contractura, determinando el lado de la mama que se contractura. Los hallazgos microbiológicos de las cápsulas periprotésicascontracturadas demostraron que un mayor grado de contractura en aquellos implantes en los que hubo resultados microbiológicos positivos, encontrando Propionibacteriumacnes y especies de estafilococos coagulasa negativos. Conclusiones. Las pacientes con implantes mamarios que realizan ejercicio físico habitual presentan mayor riesgo de sufrir contractura capsular mamaria.

Full Text Available La neutropenia febril prolongada conlleva un alto riesgo de desarrollar infecciones fúngicas invasoras, por lo que habitualmente se administra terapia antifúngica empírica en estos casos. Sin embargo, esta se asocia a importantes efectos adversos, por lo que se ha propuesto como alternativa la estrategia "preemptive" o anticipada, es decir, la indicación de antifúngicos sólo ante la evidencia indirecta de infección fúngica invasora. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en 30 bases de datos, identificamos tres revisiones sistemáticas que en conjunto incluyen doce estudios. Cuatro estudios aleatorizados evaluaron la pregunta abordada en este artículo. Realizamos un metanálisis y tablas de resumen de los resultados utilizando el método GRADE. Concluimos que no está claro si la estrategia "preemptive" tiene algún efecto sobre la mortalidad porque la certeza de la evidencia es muy baja, pero podría disminuir levemente el uso de antifúngicos en pacientes con neutropenia febril prolongada.

To assess the efficacy of diazepam suppositories at preventing febrile seizure recurrence during a single febrile illness to determine how to treat children with a febrile seizure on presentation at the hospital. We studied 203 children with febrile seizures from December 2004 through March 2006. On admission between December 2004 and May 2005, a diazepam suppository was administered to the patients. Patients seen between June 2005 and March 2006 were not treated with antiepileptic drugs on admission. We saw a significant difference in the rate of recurrence of febrile seizures between children treated with diazepam and those who were not. Recurrences were observed in 2 (2.1%) of 95 children treated with diazepam and in 16 (14.8%) of 108 untreated children. For the 108 untreated patients, the median age was 22.8 months in those with recurrences and 30.6 months in those without, confirming that a younger age was related to a recurrence. A diazepam suppository after a febrile seizure will reduce the incidence of recurrent febrile seizures during the same febrile illness. However, a diazepam suppository after a febrile seizure should be used after carefully considering the benefits and potential adverse effects.

Full Text Available Introducción La utilización de drenaje en la artroplastia total de rodilla es una práctica ampliamente aceptada en la comunidad ortopédica; sin embargo, en la bibliografía, no se encuentra evidencia concluyente sobre su beneficio. El propósito de este estudio fue comparar dos grupos de pacientes sometidos a artroplastia total de rodilla         primaria con drenaje y sin él. Materiales y Métodos Se llevó a cabo un estudio prospectivo aleatorizado en el que se realizaron 76 artroplastias totales de rodilla primarias; se dividió a los pacientes en dos grupos: grupo A, con drenaje y grupo B, sin drenaje. Se evaluaron el número de unidades de sangre transfundidas, el débito de sangre en los pacientes con drenaje, las complicaciones posoperatorias y el tiempo de hospitalización. Antes de la cirugía y después de ella, se registró el diámetro del muslo, el rango de movilidad, el hematocrito y la hemoglobina en ambos grupos. Resultados No se hallaron diferencias estadísticamente significativas en el diámetro del muslo, el rango de movilidad, el hematocrito, la hemoglobina, el número de transfusiones y la estadía hospitalaria. El número de complicaciones en el grupo B (sin drenaje fue mayor (p = 0,019: dos infecciones profundas, dos casos de celulitis, uno de flictena, una fractura de cadera, una trombosis venosa superficial, una trombosis venosa profunda y un tromboembolismo pulmonar. Conclusión Los pacientes sin drenaje posoperatorio sufrieron más complicaciones.

Full Text Available El uso del láser en el tratamiento de las cicatrices hipertróficas y queloideas ha mostrado resultados aceptables. El objetivo de este trabajo es analizar y determinar la eficacia y seguridad del tratamiento combinado de dos láseres en cicatrices hipertróficas y queloideas de cualquier etiología. Se trata de un estudio prospectivo y descriptivo realizado entre enero del 2011 y junio del 2013 sobre una muestra de 40 cicatrices en una población de 30 pacientes con fototipos III a VI. Se utilizó la escala de Vancouver para cicatrices (VSS y la escala de evaluación objetiva de paciente y observador (POSAS para valorar los resultados. En la primera fase se empleó el láser no ablativo de Nd:YAG de 1064 nm hasta computar 6 sesiones. A continuación, en la segunda fase, se empleó un láser de CO² a 20W fraccionado, practicándose de 4 a 7 sesiones. Se realizaron evaluaciones 6 meses después del último tratamiento. Tras el análisis de los resultados conseguidos en la VSS, observamos mejoría en todas las variables. Los parámetros que mostraron una mejoría más notable fueron la vascularización y la flexibilidad de la piel. El prurito fue el síntoma donde más remisión se experimentó y además, la limitación funcional generada por las cicatrices ubicadas en zonas anatómicas de movilidad se recuperó en el 80 % , en el mejor de los casos. La remodelación de cicatrices con láser puede plantearse como una alternativa en el manejo de las cicatrices hipertróficas y queloideas de cualquier etiología, empleando parámetros adecuados según cada caso.

Full Text Available Febrile seizures are the most frequent neurological disorder in the childhood. According to American Academy of Pediatrics (AAP, they have been defined as seizures provoked by high temperature in children aged between 6 months and 5 years, without previous history of afebrile seizures, intracranial infections and other possible causes of seizures. Seizures can be typical and atypical, according to the characteristics. Pathogenesis of this disorder has not been clarified yet, and it is believed to be a combination of genetic factors, high body temperature and brain maturation. The risk factors for recurrence of febrile seizures are: age in which seizures appeared for the first time, epilepsy in the first degree relative, febrile seizures in the first degree relative, frequent diseases with fever and low body temperature on the beginning of seizures. The frequency of recurrent seizures The risk for occurrence of epilepsy in children with simple seizures is about 1-1.5%, which is slightly higher compared to general population, while it increases to 4-15% in patients with complex seizures. However, there is no evidence that therapy prevents occurrence of epilepsy. When the prevention of recurrent seizures is considered, it is necessary to separate simple from complex seizures. The aim of this paper was to analyze the most important risk factors for febrile seizures, and to evaluate their impact on occurrence of recurrent seizures. Our study included 125 children with febrile seizures, aged from 6 months to 5 years. The presence of febrile seizures and epilepsy in the first degree relative has been noted in 22% of children. Typical febrile seizures were observed in 76% of cases, and atypical in 24%. Most patients had only one seizure (73.6%. Children, who had seizure earlier in life, had more frequent recurrences. Both risk factors were present in 25% of patients, while 68% of patients had only one risk factor. For the children with febrile disease

Full Text Available A neutropenia febril (NF é uma complicação frequente e potencialmente fatal nos pacientes em tratamento quimioterápico. Entendemos hoje que a neutropenia febril é considerada uma emergência clínica e que a administração de antibióticos de amplo espectro diminui drasticamente a mortalidade. Estudos sugerem que a neutropenia febril compreende um grupo extremamente heterogêneo e que dados clínicos como febre domiciliar, ausência de hipotensão, ausência de desidratação, ausência de doença pulmonar obstrutiva crônica, ausência de outros sintomas, ausência de infecção fúngica prévia e idade Febrile neutropenia is a frequent and potentially fatal adverse event of chemotherapy. Nowadays, febrile neutropenia is considered an emergency and it is known that prompt infusion of antibiotics decreases mortality. Several studies demonstrated that febrile neutropenia is a heterogeneous group of diseases and that factors such as outpatient status, no hypotension, no dehydration, no chronic obstructive pulmonary disease, no symptoms, no previous fungal infection and age < 60 years are protective factors against serious complications as demonstrated by the Multinational Association for Supportive Care in Cancer (MASCC. These data show that outpatient treatment and early discharge is safer and much research has shown lower costs for outpatient treatment in low-risk patients with febrile neutropenia. The aim of this work is to review and discuss tools (in particular the MASCC index for safe screening of febrile neutropenia for outpatient treatment in addition to demonstrate results of research.

BACKGROUND: Febrile seizure is a benign condition for most children, but experiments in animals and neuroimaging studies in humans suggest that some febrile seizures may damage the hippocampus, a brain area of possible importance in schizophrenia. METHODS: A population-based cohort of all children...... with schizophrenia. A history of febrile seizures was associated with a 44% increased risk of schizophrenia [relative risk (RR)=1.44; 95% confidence interval (CI), 1.07-1.95] after adjusting for confounding factors. The association between febrile seizures and schizophrenia remained virtually unchanged when...... restricting the analyses to people with no history of epilepsy. A history of both febrile seizures and epilepsy was associated with a 204% increased risk of schizophrenia (RR=3.04; 95% CI, 1.36-6.79) as compared with people with no such history.

El tratamiento de los pacientes con neoplasia y neutropenia febril plantea muchas dudas. Una de ellas, que genera ansiedad en el personal de la salud, el paciente y sus familiares, es la necesidad de hospitalización porque ésta implica exponer a gérmenes intrahospitalarios potencialmente resistentes a un paciente cuyo sistema inmune puede no estar en las mejores condiciones; incluso con un aislamiento óptimo existe el riesgo de adquirir una infección nosocomial. Muchos estudios han tratado de validar métodos para clasificar a los pacientes con fiebre y neutropenia en grupos de diferente riesgo, como fundamento para implementar estrategias de tratamiento selectivo; así se ha abierto la posibilidad de utilizar medidas más conservadoras para el tratamiento de los episodios de bajo riesgo, entre ellas la administración de regímenes orales ambulatorios de antibióticos de amplio espectro; ello sin demeritar la necesidad de aplicar un juicio clínico adecuado, hacer un buen seguimiento y tener acceso a la atención médica inmediata. La neutropenia es una de las consecuencias graves de la quimioterapia para el cáncer, y se ha demostrado que el tratamiento del paciente neutropénico febril con antibióticos intravenosos reduce la mortalidad. La terapia oral podría ser una alternativa aceptable para pacientes bien seleccionados. Ella puede mejorar la calidad de vida de los pacientes con cáncer, evitar las complicaciones asociadas con la terapia intravenosa y disminuir los costos del tratamiento.

Treatment of patients with neoplasia and febrile neutropenia, as a consequence of chemotherapy, poses many doubts, among them the need for hospitalization, since this implies exposure to potentially resistant nosocomial microorganisms. Even under the best isolation techniques, there may

Full Text Available Endocan is an endotelial cell specific molecule; previous studies have shown that serum endocan levels increased in cancer and sepsis and are also related to the severity of sepsis. There are no clinical study about serum endocan levels in children with febrile neutropenia. The aim of this study was to evaluate serum endocan levels in pediatric leukemia patients with febrile neutropenia (n=33 and compare them with children with leukemia without fever (n=33 and also with healthy children (n=24. The median serum endocan level in the first group (children with febrile neutropenia was statistically significantly higher compared to the leukemic children without febrile neutropenia and also control group (P<0.01 for both. No difference was determined between the serum endocan levels of the leukaemia patients without febrile neutropenia and the healthy control group (P>0.05. Serum endocan levels were also similar with febrile neutropenia due to bacterial causes comparing with the idiopathic febril neutropenia. The results of this study showed increased serum endocan in children with leukemia during the febrile neutropenia episode, and no changes of serum endocan levels in children without leukemia without infection/fever. The monitoring of a series of serum endocan levels would be helpful for the course of febrile neutropenia.

Full Text Available Las convulsiones febriles representan la mayoría de las convulsiones en el niño. Se ha descrito que 2-5% de los niños experimentan convulsiones febriles antes de los 5 años de edad, aunque en algunas poblaciones se ha descrito hasta un 15%. Es una causa común de admisión en pediatría y de preocupación de los padres. Puede ser la primera manifestación de una epilepsia. Un 13% de pacientes que desarrollan epilepsia tienen antecedente de convulsiones febriles y 30% de estos pacientes se presentan con convulsiones recurrentes. Sus características fenotípicas nos permiten, en su gran mayoría, clasificarlas, tomar una actitud terapéutica y elaborar un pronóstico. Se puede describir un espectro de su gravedad desde las convulsiones febriles simples hasta las más complejas como las convulsiones febriles plus que comprenden los síndromes de Dravet y FIRES. En los últimos años se han hecho descubrimientos importantes que definen su carácter genético, entrelazándose cada vez más con diferentes afecciones de tipo epiléptico que nos obliga a un seguimiento neurológico más estrecho de muchos de estos niños con convulsiones febriles. Hacemos una revisión bibliográfica con el objetivo de actualizar los conocimientos sobre las convulsiones febriles, su pronóstico y su relación con los nuevos síndromes epilépticos.

Full Text Available En pacientes con cáncer que se presentan con neutropenia febril existe controversia sobre si es mejor utilizar una combinación de antibióticos betalactámicos y aminoglicósidos o si bastaría la monoterapia con betalactámicos de amplio espectro como tratamiento empírico inicial. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en 30 bases de datos, identificamos tres revisiones sistemáticas que en conjunto incluyen 14 estudios aleatorizados pertinentes a esta pregunta. Realizamos un metanálisis y tablas de resumen de los resultados utilizando el método GRADE. Concluimos que adicionar aminoglicósidos a los betalactámicos en el tratamiento de la neutropenia febril en pacientes con cáncer aumenta la nefrotoxicidad y podría aumentar la mortalidad en comparación con la monoterapia con betalactámicos.

Full Text Available El tratamiento con drogas citotóxicas en el paciente oncológico, tiene como toxicidad limitante de dosis más común la neutropenia y sus complicaciones infecciosas. Su aparición provoca retrasos y reducción de dosis en los ciclos posteriores de quimioterapia, así como deterioro en la calidad de vida de los pacientes. El colectivo de Medicina Oncológica, que incluye el Servicio de Farmacia, decidió realizar un estudio, con el objetivo de analizar la aparición de neutropenia febril tras la administración de la terapia citotóxica y la presencia de otros factores que pueden incrementar el riesgo de estas reacciones. Se estudiaron los 42 pacientes que ingresaron con neutropenia febril tras el tratamiento citotóxico en el periodo comprendido entre febrero y agosto del 2007. Se recogieron variables biomédicas del grupo de pacientes incluidos y se analizó el tratamiento citostático empleado previamente. El grupo de edad que prevaleció fue el de los pacientes mayores de 50 años, con un predomino del sexo masculino y los estadios avanzados con afecciones asociadas. Las localizaciones tumorales más frecuentes radicaron en mama, pulmón y linfoma no Hodgkin. El citostático más señalado en casos de neutropenia febril resultó la adriamicina con un 71,4 %, seguido de la ciclofosfamida con 52,4 %. Los factores que más se asociaron con la aparición de neutropenia febril fueron: quimioterapia con antraciclinas, la edad mayor de 50 años, estadios avanzados y presencia de enfermedades asociadas.Treatment of oncology patient using cytotoxic drugs has the neutropenia and its infectious complications as the commonest dose-limiting toxicity.

Full Text Available Objectives: To determine the prevalence of benign febrile seizures of childhood and describe the clinical and epidemiological profile of this population. Methods: This was a population-based, cross-sectional study, carried out in the city of Barra do Bugres, MT, Brazil, from August 2012 to August 2013. Data were collected in two phases. In the first phase, a questionnaire that was previously validated in another Brazilian study was used to identify suspected cases of seizures. In the second phase, a neurological evaluation was performed to confirm diagnosis. Results: The prevalence was 6.4/1000 inhabitants (95% CI: 3.8–10.1. There was no difference between genders. Simple febrile seizures were found in 88.8% of cases. A family history of febrile seizures in first-degree relatives and history of epilepsy was present in 33.3% and 11.1% of patients, respectively. Conclusions: The prevalence of febrile seizures in Midwestern Brazil was lower than that found in other Brazilian regions, probably due to the inclusion only of febrile seizures with motor manifestations and differences in socioeconomic factors among the evaluated areas.

Full Text Available Un estudio reciente destacó la presencia de Granulicatella spp. en episodios de bacteriemia en pacientes neutropénicos, a diferencia de Abiotrophia defectiva, que sólo se había observado en endocarditis infecciosa. El objetivo de esta presentación es describir un caso de bacteriemia por A. defectiva en un niño leucémico, neutropénico (200 GB/mm³ y febril (40 °C. En una de las muestras de hemocultivo se obtuvo el desarrollo de A. defectiva. A pesar de que el paciente estudiado cursaba una varicela, lo que podría justificar el episodio febril, el hallazgo de A. defectiva en el hemocultivo se interpretó como perteneciente a una bacteriemia verdadera ya que esta especie, según nuestros conocimientos, no forma parte de la flora habitual de la piel. Este caso sugiere que A. defectiva también puede ser responsable de casos de bacteriemia en pacientes inmunocomprometidos.The presence of Granulicatella spp. in bacteremic episodes of neutropenic patients was recently highlighted whereas Abiotrophia defectiva, was only isolated in cases of infectious endocarditis. The aim of this study is to describe a case of A.defectiva bacteremia in a leukemic and febrile (40 °C neutropenic (200 GB/mm³ boy. A.defectiva was only isolated from one of the two processed blood samples . Although the patient was undergoing an episode of varicela which could have accounted as the possible cause of fever, A. defectiva was considered a significant finding because this species is not part of the commensal skin flora. This case suggests that both A. defectiva and Granulicatella spp. should be regarded as possible causes of bacteremia in immunocompromised patients.

We describe the management of a 4-year-old child with acute lymphoblastic leukaemia (ALL) who presented with febrile neutropenia, Cryptosporidium and subsequently developed refeeding syndrome. Febrile neutropenia is common and can be life-threatening and we highlight the identification of well low-risk neutropenic children with resolved febrile illnesses suitable for early discharge. We also discuss the potential management strategies for Cryptosporidium Refeeding syndrome is not common, but should be considered as a cause of acute inpatient deterioration and is a significant risk, with potential morbidity, in children who have undergone a period of catabolism. This article reviews the current literature and provides useful guidance on these issues. Published by the BMJ Publishing Group Limited.

Full Text Available The influence of experimentally Escherichia coli-induced fever (EEIF on the pharmacokinetics of ofloxacin was evaluated. Ofloxacin was administered @ 20 mg.kg-1 body weight intravenously to a group of eight healthy rabbits and compared these results to values in same eight rabbits with EEIF. Pharmacokinetic parameters of ofloxacin in normal and febrile rabbits were determined by using two compartment open kinetic model. Peak plasma level (Cmax and area under the plasma concentration-time curve (AUC0-α in normal and febrile rabbits did not differ (P>0.05. However, area under first moment of plasma concentration-time curve (AUMC0-α in febrile rabbits was significantly (P<0.05 higher than that in normal rabbits. Mean values for elimination rate constant (Ke, elimination half life (t1/2β and apparent volume of distribution (Vd were significantly (P<0.05 lower in febrile rabbits compared to normal rabbits, while mean residence time (MRT and total body clearance (Cl of ofloxacin did not show any significant difference in the normal and febrile rabbits. Clinical significance of the above results can be related to the changes in the volume of distribution and elimination half life that illustrates an altered steady state in febrile condition; hence, the need for an adjustment of dosage regimen in EEIF is required.

Febrile neutropenia in haematological malignancies

Directory of Open Access Journals (Sweden)

2005-01-01

Full Text Available Fever is the principle sign of infection in neutropenic patient and frequently may be the only evidence of infection. The pattern of fever in neutropenia is non-specific and not pathognomonic of any type of infections or non-infectious process and can be suppressed by the antipyretic effects of drugs such as corticosteroids. Neutropenia, resulting from cytotoxic chemotherapy is the most common risk factor for severe infections in hematological malignancies. The duration of neutropenia also contributes significantly to the risk of serious infections. This risk is significantly greater a lower neutrophil counts, such that 100% patients with ANC < 100 cells/µl lasting 3 weeks or more develop documented infections. The prompt initiation of empirical antibiotics in febrile neutropenia has been the most important advance in the management of the immunocompromised host. The initial empirical antibiotic regimen started at presentation of the febrile episode frequently requires modifications especially in high-risk febrile neutropenia. Neutropenic patients who remain febrile despite 4-7 days of broad spectrum antibacterial therapy are at a high risk of invasive fungal infection. Empirical antifungal therapy with Amphotericin B in persistently febrile neutropenic patients and other high risk patients has shown to reduce the risk of invasive fungal infection by 50-80% and the risk of fungal infection related mortality by 23-45% in 1980′s. The IDSA has recommended that amphotericin B at 0.5-0.7 mg/kg/day be administered till marrow recovery. This approach is limited however by the adverse effects caused by drug infusion (fever, chills, myalgias, nausea, hypotension and bronchospasm. Lipid formulations which improve the therapeutic ratio of the traditional formulation are available. The safety and efficacy of these formulations is well established. These formulations have comparable efficacy and are less nephrotoxic than conventional amphotericin B

Epilepsy, febrile seizures, and attention-deficit/hyperactivity disorder (ADHD) are disorders of the central nervous system and share common risk factors. Our goal was to examine the association in a nationwide cohort study with prospective follow-up and adjustment for selected confounders. We hypothesized that epilepsy and febrile seizures were associated with subsequent ADHD. A population-based cohort of all children born in Denmark from 1990 through 2007 was followed up until 2012. Incidence rate ratios (IRRs) and 95% confidence intervals (95% CIs) for ADHD were estimated by using Cox regression analysis, comparing children with epilepsy and febrile seizure with those without these disorders, adjusted for socioeconomic and perinatal risk factors, as well as family history of neurologic and psychiatric disorders. A total of 906 379 individuals were followed up for 22 years (∼10 million person-years of observation); 21 079 individuals developed ADHD. Children with epilepsy had a fully adjusted IRR of ADHD of 2.72 (95% CI, 2.53-2.91) compared with children without epilepsy. Similarly, in children with febrile seizure, the fully adjusted IRR of ADHD was 1.28 (95% CI, 1.20-1.35). In individuals with both epilepsy and febrile seizure, the fully adjusted IRR of ADHD was 3.22 (95% CI, 2.72-3.83). Our findings indicate a strong association between epilepsy in childhood and, to a lesser extent, febrile seizure and subsequent development of ADHD, even after adjusting for socioeconomic and perinatal risk factors, and family history of epilepsy, febrile seizures, or psychiatric disorders.

Full Text Available Febrile seizures are the commonest acute neurological disorder of early childhood. Studies suggested that febrile seizures are previous acute events from a more serious neurological problem. Due to neuron-specific enolase is generally accepted as a marker for neuropathological processes in the brain, 16 pediatric patients were studied during their first seizures and a year after it. Neuron-specific enolase in cerebrospinal fluid and blood were analysed by an immune enzyme assay. Non pathological neuron-specific enolase values were obtained in both periods in the group of patients. There were no significative differences when paired series statistics test was performed with 95% of confidence. Neuron-specific enolase appears not to be a marker for febrile seizures because its concentration not be increased in cerebrospinal fluid in this group of patients.Los ataques febriles constituyen el trastorno neurológico agudo más común en la infancia temprana. Existen estudios que sugieren que los ataques febriles son eventos agudos previos a problemas neurológicos más severos. Debido a que la enolasa específica de neurona está aceptada generalmente como marcador de procesos neuropatológicos en el cerebro, se estudiaran 16 pacientes pediátricos durante su primer ataque y al año de este. La enolasa específica de neurona en el líquido cefalorraquídeo y sangre fue analizada por una prueba inmunoenzimática. No se obtuvieron valores patológicos de enolasa específica de neurona en ambos períodos en el grupo de pacientes. No hubo diferencias significativas al aplicar el test de series apareadas con un 95% de confianza. La enolasa específica de neurona parece no ser un marcador para ataques febriles porque su concentración no se incrementa en este grupo de pacientes.

Methods: Forty young adults with acute lymphoblastic leukemia, at the beginning of maintenance course of their chemotherapy, were eligible for this study. The study population was randomized in a double blind manner to receive either taurine or placebo (2 gram per day orally. Life quality and side effects including febrile episodes were assessed using questionnaire. Data were analyzed using Pearson’s Chi square test. Results: Of total forty participants, 43.8% were female and 56.3 % were male. The mean age was 19.16±1.95 years (ranges: 16-23 years. The results indicated that the levels of white blood cells are significantly (P<0.05 increased in taurine treated group. There was no elevation in blasts count. A total of 70 febrile episodes were observed during study, febrile episodes were significantly (P<0.05 lower in taurine patients in comparison to the control ones. Conclusion: The overall incidence of febrile episodes and infectious complications in acute lymphoblastic leukemia patients receiving taurine was lower than placebo group. Taurine’s ability to increase leukocyte count may result in lower febrile episodes.

A family history of seizures, preexisting brain damage, or birth complications may modify the long-term risk of epilepsy after febrile seizures. The authors evaluated the association between febrile seizures and epilepsy in a population-based cohort of 1.54 million persons born in Denmark (1978......-2002), including 49,857 persons with febrile seizures and 16,481 persons with epilepsy.

Uda, Kazuhiro; Kitazawa, Katsuhiko

2017-08-01

Febrile status epilepticus can have neurological sequelae. The type of sequelae, however, depend on the etiology, including infection due to viral agents such as the influenza virus. Respiratory syncytial virus (RSV) infection in childhood may also contribute to this. The aim of this study was therefore to characterize febrile status epilepticus associated with RSV infection, and to determine whether this type of infection is a risk factor for neurological sequelae in febrile status epilepticus. We reviewed the medical records of children aged ≤3 years with febrile status epilepticus who were admitted to a tertiary hospital between January 2007 and December 2011. The differences between the RSV-positive and RSV-negative groups were evaluated according to the demographic and clinical data. A total of 99 patients with febrile status epilepticus who had been tested for RSV infection were identified. Three patients in the RSV-positive group (n = 19) and four in the RSV-negative group (n = 80) presented with bronchiolitis. The incidence of intubation and anti-seizure drug treatment in the RSV-positive group was significantly higher than in the -negative group. While all of the patients in the RSV-negative group recovered completely, six patients in the RSV-positive group developed encephalopathy and profound neurological sequelae. In five of the six patients, diffusion-weighted magnetic resonance imaging showed subcortical white matter lesions. RSV infection in the absence of bronchiolitis can initially present as febrile status epilepticus and subsequently develop into acute encephalopathy with profound neurological sequelae. © 2017 Japan Pediatric Society.

Simple febrile convulsion is the most common disease of the nervous system in children. There are hypotheses that iron deficiency may affect febrile convulsion and the threshold of neuron excitation. This study was conducted with the objective of finding the effects of iron deficiency anemia on simple febrile convulsion episodes. The study was conducted at AmirKabir Hospital of Arak Medical Sciences University, Arak, Iran. This is a case-control study. In this study, 382 children who were selected according to our inclusion and exclusion factors, were divided into two groups of case (febrile convulsion) and control (other factors causing fever) by their cause of hospitalization. After fever subsided, 5 ml blood sample was taken from each child and complete blood count and iron profile tests were performed. The results were interpreted using descriptive statistics and independent t-test. The prevalence of anemia in the group with febrile convulsion was significantly less than that in the control group: 22.5% of the children in the group with febrile convulsion and 34% in the control group exhibited anemia (P < 0.001). Moreover, the group with febrile convulsion had significantly higher blood indices, such as Hb, Hct, MCV, MCH, and MCHC, compared to the control group (P < 0.001). Iron deficiency can prevent febrile convulsion in children and probably increases the threshold of neuron excitation in fever.

This study compares the performance of urine dipstick alone with urine microscopy and with both tests combined as a screen for urinary tract infection (UTI) in febrile infants aged 1 to 90 days. We queried the Intermountain Healthcare data warehouse to identify febrile infants with urine dipstick, microscopy, and culture performed between 2004 and 2011. UTI was defined as >50 000 colony-forming units per milliliter of a urinary pathogen. We compared the performance of urine dipstick with unstained microscopy or both tests combined ("combined urinalysis") to identify UTI in infants aged 1 to 90 days. Of 13 030 febrile infants identified, 6394 (49%) had all tests performed and were included in the analysis. Of these, 770 (12%) had UTI. Urine culture results were positive within 24 hours in 83% of UTIs. The negative predictive value (NPV) was >98% for all tests. The combined urinalysis NPV was 99.2% (95% confidence interval: 99.1%-99.3%) and was significantly greater than the dipstick NPV of 98.7% (98.6%-98.8%). The dipstick positive predictive value was significantly greater than combined urinalysis (66.8% [66.2%-67.4%] vs 51.2% [50.6%-51.8%]). These data suggest 8 febrile infants would be predicted to have a false-positive combined urinalysis for every 1 infant with UTI initially missed by dipstick screening. Urine dipstick testing compares favorably with both microscopy and combined urinalysis in febrile infants aged 1 to 90 days. The urine dipstick test may be an adequate stand-alone screen for UTI in febrile infants while awaiting urine culture results. Copyright © 2014 by the American Academy of Pediatrics.

International Nuclear Information System (INIS)

Sherjil, A.; Saeed, Z.U.; Shehzad, S.; Amjad, R.

2010-01-01

Background: Iron deficiency anaemia and febrile seizures are two common diseases in children worldwide as well as in our country. Iron insufficiency is known to cause neurological symptoms like behavioural changes, poor attention span and learning deficits in children. Therefore, it may also be associated with other neurological disturbances like febrile seizures in children. Objective of our case-control study was to find association between iron deficiency anaemia and febrile seizures in children. Methods: This multicentre study was conducted in Department of Paediatrics HIT Hospital Taxila Cantt, Department of Paediatrics CMH Mangla and Department of Paediatrics POF Hospital Wah Cantt, from June 2008 to June 2010. Three hundred and ten children aged between 6 months to 6 years were included in the study. One hundred and fifty-seven children who presented with febrile seizures were our cases, while, 153 children who presented with febrile illnesses without seizures were recruited as controls. All patients were assessed for iron deficiency anaemia by measuring haemoglobin level, serum ferritin level, Mean Corpuscular Haemoglobin Concentration (MCHC) and Mean Corpuscular Volume (MCV). Patients with iron deficiency anaemia amongst controls and cases were documented. Percentages and Odds ratio were derived from the collected data. Results: 31.85% of cases (50 out of 157) had iron deficiency anaemia whereas, 19.6% of controls (30 out of 153) were found to have iron deficiency anaemia as revealed by low levels of haemoglobin level, serum ferritin level, Mean Corpuscular Haemoglobin Concentration and Mean Corpuscular Volume. Odds ratio was 1.93. Conclusion: Patients with febrile seizures are 1.93 times more likely to have iron deficiency anaemia compared to febrile patients without seizures. (author)

Full Text Available OBJECTIVE: Patients with neutropenia due to cancer chemotherapy are prone to severe infections. Cancer patients can experience >1 infectious episode during the same period of neutropenia. This study aimed to determine the etiological and clinical characteristics of secondary infectious episodes in cancer patients with febrile neutropenia and to identify the factors associated with the risk of secondary infectious episodes. METHODS: All cancer patients that received antineoplastic chemotherapy at Ankara University, School of Medicine, Department of Hematology between May 2004 and May 2005 and developed neutropenia were included in the study. Data were collected using survey forms that were completed during routine infectious diseases consultation visits. Categorical data were analyzed using the chi-square test, whereas Student’s t-test was used for continuous variables. Multivariate logistic regression analysis was performed to identify independent predictors of secondary infections (SIs. RESULTS: SIs were observed during 138 (53% of 259 febrile neutropenic episodes. Of the 138 episodes, 89 (64.5% occurred in male patients with a mean age of 40.9 years (range: 17-76 years. In total, 80% of the SIs were clinically or microbiologically documented. Factors on d 4 of the initial febrile episode were analyzed via a logistic regression model. The presence of a central intravenous catheter (OR: 3.01; P < 0.001, acute myeloid leukemia (AML as the underlying disease (OR: 2.12; P = 0.008, diarrhea (OR: 4.59; P = 0.005, and invasive aspergillosis (IA during the initial febrile episode (OR: 3.96; P = 0.009 were statistically significant risk factors for SIs. CONCLUSION: Among the cancer patients with neutropenia in the present study, AML as the underlying disease, the presence of a central venous catheter, diarrhea, and IA during the initial febrile episode were risk factors for the development of SIs.

Full Text Available Febrile convulsions (FC are the most common neurologic disorder in children 6-60 months of age. Zinc (Zn and copper (Cu play role as cofactors in more than 300 enzymatic activities significantly. The aim of this study was to evaluate the relationship serum levels of Zn and Cu with seizure occurrence in febrile children. In this case-control study, 270 children with 6 month to 6 years were evaluated. The patients were enrolled in three groups: a children with febrile convulsion, b febrile children without convulsion and c healthy ones. After recording of all patients’ characteristics, 5 mL blood was taken from peripheral vessels at the first 12 hours of hospitalization. Absorption of all samples was read by BRAIC (Rayleigh instrument company, WFX-130 model with calibration diagram, considering samples dilution levels. The mean of serum Zn levels in children with FC were significantly lower than other two groups. Mean serum Cu levels in children with FC and non-FC patients were significantly higher than healthy children. No meaningful differences were observed in serum levels of Zn and Cu among the girl or boy cases. This study showed significant lower serum zinc level in children with febrile seizure and meaningful higher serum copper level than control group cases. There was no significant difference in level of serum zinc and copper in term of sex.

Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.

Full Text Available En este trabajo se analizan los datos de un estudio longitudinal a largo plazo con el objetivo de examinar las implicaciones de los rasgos psicopáticos infanto-juveniles, evaluados a través de la mCPS (modified Child Psychopathy Scale, en la conducta antisocial en la adolescencia. Se analizan los datos recogidos en 141 niños (edad media = 7.80, que fueron seguidos seis y diez años más tarde. Los resultados muestran que los niños con altas puntuaciones en rasgos psicopáticos presentan en la adolescencia temprana niveles relativamente altos de problemas de conducta. Además, a lo largo de la adolescencia se produce en ellos un mayor incremento en implicación con amigos antisociales, consumo de cannabis y agresión proactiva. Así, los resultados muestran que los rasgos psicopáticos medidos en la niñez se asocian con un desarrollo más desfavorable, particularmente en indicadores que, como la agresión proactiva, se han vinculado clásicamente a la personalidad psicopática en adultos.

Objective: To evaluate the oxidative status following a seizure in children experiencing a simple febrile seizure. Methods: The cross-sectional study was conducted at Harran University, Turkey, between January and September 2011. It comprised 32 paediatric patients who, within the preceding 8 hours, had experienced a seizure due to upper respiratory tract infection and had been diagnosed with simple febrile seizure, and 30 healthy children as the control group. Blood was taken from the patients 8 hours after the seizure. Total oxidant level and Total anti-oxidant level were measured according to the Erel technique and the oxidative stress index was calculated. Data was analysed using SPSS 11.5. Results: The mean values of the total oxidant level and the oxidative stress index of the cases were found to be significantly high compared to the controls and the total anti-oxidant level was found to be significantly low (p<0.01, p<0.01, p<0.03 respectively). Conclusion: The increased total oxidant level and decreased total anti-oxidant level resulting in increased oxidative stress associated with febrile seizure patients may increase the risk of experiencing febrile seizures.

The neurobiology of the human febrile response.

Science.gov (United States)

Biddle, Chuck

2006-04-01

Fever is a normal adaptation in response to a pyrogenic stimulus resulting in the generation of cytokines and prostaglandins. Fever differs from hyperpyrexia and hyperthermia associated with hot environs and pharmacological triggers. Typically, pyrogens are infectious organisms or their direct products (toxins). The body produces a wide array of pyrogenic cytokines such as interleukins (IL-1, IL-6), interferon, and tumor necrosis factor. Tissue trauma can trigger the febrile response, as can infectious organisms, certain medications, and blood products. The circumventricular organ system (CVOS) is neuronal tissues lying outside the blood-brain barrier that has a key role in initiating the communication sequence responsible for the synthesis of febrile prostaglandins. When pyrogenic cytokines are detected by the CVOS, prostaglandin synthesis, especially cyclooxygenase-dependent prostaglandin E2, is induced, activating the febrile response. Once the appropriate signal is received by the hypothalamus, autonomic, endocrine, and behavioral processes are activated until the hypothalamic set-point is reset downward as a consequence of a reduction in pyrogen content or antipyretic therapy, with subsequent heat loss. There is little evidence that fever facilitates recovery from disease or assists the immune system in mounting a response. Antipyretics are used commonly to decrease the distressing manifestations associated with fever.

Atypical febrile seizures, mesial temporal lobe epilepsy, and dual pathology.

2012-01-01

Febrile seizures occurring in the neonatal period, especially when prolonged, are thought to be involved in the later development of mesial temporal lobe epilepsy (mTLE) in children. The presence of an often undetected, underlying cortical malformation has also been reported to be implicated in the epileptogenesis process following febrile seizures. This paper highlights some of the various animal models of febrile seizures and of cortical malformation and portrays a two-hit model that efficiently mimics these two insults and leads to spontaneous recurrent seizures in adult rats. Potential mechanisms are further proposed to explain how these two insults may each, or together, contribute to network hyperexcitability and epileptogenesis. Finally the clinical relevance of the two-hit model is briefly discussed in light of a therapeutic and preventive approach to mTLE.

Full Text Available Non-malaria febrile illnesses such as bacterial bloodstream infections (BSI are a leading cause of disease and mortality in the tropics. However, there are no reliable, simple diagnostic tests for identifying BSI or other severe non-malaria febrile illnesses. We hypothesized that different infectious agents responsible for severe febrile illness would impact on the host metabolome in different ways, and investigated the potential of plasma metabolites for diagnosis of non-malaria febrile illness.We conducted a comprehensive mass-spectrometry based metabolomics analysis of the plasma of 61 children with severe febrile illness from a malaria-endemic rural African setting. Metabolite features characteristic for non-malaria febrile illness, BSI, severe anemia and poor clinical outcome were identified by receiver operating curve analysis.The plasma metabolome profile of malaria and non-malaria patients revealed fundamental differences in host response, including a differential activation of the hypothalamic-pituitary-adrenal axis. A simple corticosteroid signature was a good classifier of severe malaria and non-malaria febrile patients (AUC 0.82, 95% CI: 0.70-0.93. Patients with BSI were characterized by upregulated plasma bile metabolites; a signature of two bile metabolites was estimated to have a sensitivity of 98.1% (95% CI: 80.2-100 and a specificity of 82.9% (95% CI: 54.7-99.9 to detect BSI in children younger than 5 years. This BSI signature demonstrates that host metabolites can have a superior diagnostic sensitivity compared to pathogen-detecting tests to identify infections characterized by low pathogen load such as BSI.This study demonstrates the potential use of plasma metabolites to identify causality in children with severe febrile illness in malaria-endemic settings.

To describe parent preference for treatment of febrile neutropenia and the key drivers of parental decision making, structured face-to-face interviews were used to elicit parent preferences for inpatient versus outpatient management of pediatric febrile neutropenia. Parents were presented with 4 different scenarios and asked to indicate which treatment option they preferred and to describe reasons for this preference during the face-to-face interview. Comments were recorded in writing by research assistants. A consensus approach to thematic analysis was used to identify themes from the written comments of the research assistants. A total of 155 parents participated in the study. Of these, 80 (51.6%) parents identified hospital-based intravenous treatment as the most preferred treatment scenario for febrile neutropenia. The major themes identified included convenience/disruptiveness, physical health, emotional well-being, and modifiers of parental decision making. Most parents preferred hospital-based treatment for febrile neutropenia. An understanding of issues that influence parental decision making may assist health care workers in planning program implementation and further support families in their decision-making process.

It is difficult for clinicians to predict the subsequent development of acute encephalopathy with febrile convulsive status epilepticus (AEFCSE), when febrile convulsive status epilepticus (FCSE) develops. Comparing clinical and laboratory characteristics between patients with AEFCSE and those with FCSE, we investigated the factors which predict the later development of febrile convulsive status caused by human herpesvirus 6 (HHV6). The subjects of this study were patients treated for FCSE or AEFCSE due to HHV6 in our hospital between April 2004 and January 2008. The AEFCSE group included 5 patients, and the FCSE group included 6 patients. There were few differences in clinical characteristics or brain images on admission between the 2 groups. Disturbance of consciousness persisted for 24 hours or more in all patients in the AEFCSE group and in 2 patients in the FCSE group. The serum creatinine concentration was significantly higher in the AEFCSE group. Serum creatinine concentration could be a good indicator for the prediction of AEFCSE in patients with FCSE. (author)

precoz de recto. Son múltiples los estudios realizados en todo el mundo sobre sus resultados de morbimortalidad y tasa de recidiva, pero sin embargo son muy pocos los estudios publicados sobre los resultados funcionales. El objetivo de este estudio fue analizar el efecto que esta cirugía provoca en la anatomía del canal anal y compararlo con los resultados funcionales. Material y métodos: realizamos un estudio descriptivo prospectivo de 40 pacientes: 39% mujeres, 61% hombres. En todos ellos se cumplimentó una encuesta de función esfinteriana (test de Pescatori y ecografía endoanal y manometría preoperatoria, al 3er mes postoperatorio, y al 6º sólo si apareció incontinencia Resultados: Treinta y dos pacientes (80% fueron operados de adenomas y 8 pacientes (20% de adenocarcinomas uT1. Tres pacientes presentaron incontinencia a gases al 3er mes postoperatorio que se normalizó al 6º mes. Valores de la manometría anorrectal: la presión media en reposo (PMR había disminuido a los 3 meses con respecto al valor preoperatorio de 87,2 a 70,1 mmHg, al igual que la presión máxima de contracción (PMC de 152,5 mmHg de forma preoperatoria a 142,2 mmHg. Ecográficamente se pudo demostrar rotura del esfínter anal interno en 3 pacientes, estando en todos los pacientes íntegro el esfínter externo. Conclusiones: durante el tiempo quirúrgico de la TEM y debido al diámetro del rectoscopio (40 mm, existe una dilatación mantenida del canal anal. Esto unido al hecho de que es frecuente que haya que modificar la posición del mismo, se traduce, en algunos casos, en un riesgo de rotura del EAI, con la consiguiente caída en la PMR. En definitiva la caída que se objetiva en las presiones endoanales tiene una mínima repercusión en la clínica a menos que exista una lesión esfinteriana lo que conlleva incontinencia, en cualquier caso siempre temporal.

Evidence for the beneficial effect of therapeutic burst-suppression coma in pediatric patients with febrile refractory status epilepticus is limited, and the clinical outcomes of this treatment strategy are largely unknown. Therefore, the aim of this study was to explore the outcomes of therapeutic burst-suppression coma in a series of children with febrile refractory status epilepticus. We retrospectively reviewed consecutive pediatric patients with febrile refractory status epilepticus admitted to our pediatric intensive care unit between January 2000 and December 2013. The clinical characteristics were analyzed. Thirty-five patients (23 boys; age range: 1-18years) were enrolled, of whom 28 (80%) developed super-refractory status epilepticus. All of the patients received the continuous administration of intravenous antiepileptic drugs for febrile refractory status epilepticus, and 26 (74.3%) achieved therapeutic burst-suppression coma. All of the patients received mechanical ventilatory support, and 26 (74.3%) received inotropic agents. Eight (22.9%) patients died within 1month. The neurologically functional outcomes at 6months were good in six (27.3%) of the 22 survivors, of whom two returned to clinical baseline. The patients with therapeutic burst-suppression coma were significantly associated with hemodynamic support than the patients with electrographic seizures control (p=0.03), and had a trend of higher 1-month mortality rate, worse 6months outcomes, and a longer duration of hospitalization. Our results suggest that therapeutic burst-suppression coma to treat febrile refractory status epilepticus may lead to an increased risk of hemodynamic instability and a trend of worse outcomes.

Summary Purpose Neuroimaging studies suggest a history of febrile seizures, and depression, are associated with hippocampal volume reductions in patients with temporal lobe epilepsy (TLE). Methods We used radial atrophy mapping (RAM), a three-dimensional (3D) surface modeling tool, to measure hippocampal atrophy in 40 patients with unilateral TLE, with or without a history of febrile seizures and symptoms of depression. Multiple linear regression was used to single out the effects of covariates on local atrophy. Key Findings Subjects with a history of febrile seizures (n = 15) had atrophy in regions corresponding to the CA1 and CA3 subfields of the hippocampus contralateral to seizure focus (CHC) compared to those without a history of febrile seizures (n = 25). Subjects with Beck Depression Inventory II (BDI-II) score ≥14 (n = 11) had atrophy in the superoanterior portion of the CHC compared to subjects with BDI-II <14 (n = 29). Significance Contralateral hippocampal atrophy in TLE may be related to febrile seizures or depression. PMID:21269286

Treatment of oncology patient using cytotoxic drugs has the neutropenia and its infectious complications as the commonest dose-limiting toxicity. Its appearance provokes dose delays and reduction during post-chemotherapy cycles, as well as the quality of life deterioration of patients. Oncology Medicine Group including the Pharmacy Service carried out a study to analyze the appearance of febrile neutropenia after cytotoxic therapy administration, and the presence of other factors that may to increase the risk to these reactions. A total of 42 patients were studied admitted with febrile neutropenia after above therapy from February to August, 2007. Biomedical variables from included patient group were achieved and the previously applied cytostatic therapy. The prevalent age-group was those patients aged over 50 and predominance of male sex and advanced stages with associated affections. The more frequent tumor locations were in breast, lung, and non-Hodgkin lymphoma. The cytostatic agent more used in cases of febrile neutropenia was Adriamycin (71.4 %) followed by Cyclophosphamide (52.4 %). The factors more associated with febrile neutropenia appearance were: Anthracycline chemotherapy, age over 50, advanced stages, and presence of associated diseases

Full Text Available Background Infection in the immunocompromised host has been a reason of concern in the clinical setting and a topic of debate for decades. In this study, the aim was to analyse the clinical profile of high-risk febrile neutropenic patients. Aims To study the clinical profile of high risk febrile neutropenia patients with the objective of identifying the most common associated malignancy, most common associated pathogen, the source of infection, to correlate the treatment and management with that of the Infectious Diseases Society of America (IDSA 2010 guidelines and to assess the clinical outcome. Methods A cross-sectional time bound study was carried out and a total of 80 episodes of high-risk febrile neutropenia were recorded among patients with malignancies from September 2011 to July 2013 with each episode being taken as a new case. Results Non-Hodgkin’s lymphoma (30 per cent was the most common malignancy associated, commonest source of infection was due to central venous catheters, the commonest pathogens were gram negative (52 per cent the treatment and management of each episode of high risk febrile neutropenia correlated with that of IDSA 2010 guidelines and the mortality rate was 13.75 per cent. Conclusion Febrile neutropenia is one of the major complications and cause of mortality in patients with malignancy and hence understanding its entire spectrum can help us reduce morbidity and mortality.

Full Text Available Introduction: Identifying clinical features that differentiate acute febrile thrombocytopaenia from acute febrile illness without thrombocytopaenia can help primary care physician to decide whether to order a full blood count (FBC. This is important because thrombocytopaenia in viral fever may signify more serious underlying aetiology like dengue infection.Objective: The aim of this study was to compare the clinical features of acute febrile patients with thrombocytopaenia and acute febrile patients without thrombocytopaenia.Methodology: This was a clinic-based cross-sectional study from May to November 2003. Consecutive patients presenting with undifferentiated fever of less than two weeks were selected from the Primary Care Centre of Hospital Universiti Kebangsaan Malaysia and Batu 9 Cheras Health Clinic. Clinical features of these patients were recorded and FBC examination was done for all patients. Thrombocytopaenia was defined as platelet count <150X109/L. The odds ratio of thrombocytopaenia for each presenting symptoms was calculated.Result: Seventy-three patients participated in this study. Among them, 45.2% had thrombocytopaenia. Myalgia and headache were common among all patients. However, nausea and vomiting occurred significantly more often among patients with thrombocytopaenia than in patients with normal platelet count (OR 2.2, 95% CI 1.1-4.5.Conclusion: Acute non-specific febrile patients presenting with symptoms of nausea and vomiting may have higher risk of thrombocytopaenia and should be seriously considered for FBC.

Current imaging recommendations for investigating any infantile febrile urinary tract infection (UTI) are ultrasound scan (US), micturating cystourethrogram (MCUG) and dimercaptosuccinic acid (DMSA) scan. The aim of this retrospective cohort study was to determine the need and indications for MCUG in the investigation of a first febrile infantile UTI, as doubts have been raised over its benefit. Information on 427 infants who had undergone US, MCUG and DMSA following a first febrile UTI was prospectively recorded. The infants were divided into two groups: A (354) with normal renal US and B (73) with abnormal US. DMSA findings were correlated with findings on MCUG. Main outcome measures were incidence of recurrent UTIs, change in management or intervention as a result of MCUG, and outcome at discharge. Only 21/354 (6%) infants in Group A had both scarring on DMSA and vesicoureteric reflux (VUR), predominantly low-grade on MCUG. In Group B (abnormal US), 23/73 (32%) had scarring on DMSA and vesicoureteric reflux, predominantly high grade on MCUG. Of the infants with non-scarred kidneys, 73% had dilating reflux. Successful conservative treatment was performed in 423 infants, and 4 infants in Group B required surgery. We recommend US and DMSA in all infantile febrile UTI cases. Where US is normal, MCUG should be reserved for those cases with abnormal DMSA. Where US is abnormal, MCUG should be performed irrespective of findings on DMSA scan. A randomized prospective study is necessary to evaluate this further. Copyright © 2009 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

El objetivo ha sido diseñar las directrices académico-docentes de la materia Proyectos del Grado de Comunicación Audiovisual. Durante los meses de octubre y noviembre de 2012, se realizó un estudio cualitativo descriptivo, de carácter exploratorio y con metodología multifuente para identificar aquellos aspectos que permiten el desarrollo de una propuesta didáctica caracterizada por el desarrollo de las competencias del estudiante. Se optó por realizar dos seminarios prospectivos como técnica de recogida de datos. Esta metodología es considerada especialmente útil para estudiar la generación de representaciones sociales, dado que a partir del debate grupal emerge el significado compartido acerca del tema de discusión. Los informantes fueron identificados como clave por el hecho de ser docentes, egresados y/o empleadores de Comunicación Audiovisual. El análisis de contenido muestra un cierto grado de consenso entre profesores, profesionales y egresados con respecto a los conocimientos/habilidades requeridos por los estudiantes y docentes para el desarrollo de un proyecto audiovisual.

Full Text Available Early diagnosis of serious bacterial infections (SBI in febrile young infants based on clinical symptoms and signs is difficult. This study aimed to evaluate the diagnostic values of circulating chemokines and C-reactive protein (CRP levels in febrile young infants < 3 months of age with suspected SBI. We enrolled 43 febrile young infants < 3 months of age with clinically suspected SBI who were admitted to the neonatal intensive care unit or complete nursing unit of the pediatric department of Kaohsiung Medical University Hospital between December 2006 and July 2007. Blood was drawn from the patients at admission, and complete blood counts, plasma levels of CRP, granulocyte colony-stimulating factor (G-CSF, and chemokines, including interleukin-8 (IL-8, macrophage inflammatory protein-1α, macrophage inflammatory protein-1β, monokine induced by interferon-γ, and monocyte chemotactic protein-1 were measured. Patients’ symptoms and signs, length of hospital stay, main diagnosis, and results of routine blood tests and microbiological culture results were recorded. Twenty-six infants (60.5% were diagnosed with SBI, while 17 (39.5% had no evidence of SBI based on the results of bacterial cultures. CRP, IL-8 and G-CSF levels were significantly higher in the infants with SBI than in those without SBI. Plasma levels of other chemokines were not significantly different between the groups. The area under the receiver-operating characteristic (ROC curve for differentiating between the presence and absence of SBI was 0.79 for CRP level. Diagnostic accuracy was further improved by combining CRP and IL-8, when the area under the ROC curve increased to 0.91. CRP levels were superior to IL-8 and G-CSF levels for predicting SBI in febrile infants at initial survey. IL-8 levels could be used as an additional diagnostic tool in the initial evaluation of febrile young infants, allowing clinicians to treat these patients more appropriately.

Full Text Available While there has been a substantial decline in lead exposure in the United States during the past two decades, mobilization of existing lead stored in bone potentially represents an important endogenous source of exposure for menopausal women. It has been hypothesized that lead may be mobilized from skeletal stores during conditions of high bone turnover, such as during menopause. However, such mobilization has not been documented in prospective studies. This discussion is focussed on some of the methodological difficulties to be anticipated in longitudinal studies of lead mobilization specific to menopause and the issues that need to be taken into account when evaluating the results of such studies. To evaluate whether lead mobilization occurs during menopause, a prospective repeated measures design is needed using X-ray fluorescence analysis of lead in bone and serial measurements of blood lead. Potential confounders and effect modifiers also need to be taken into account in the statistical analysis.Mientras que la exposición a plomo ha declinado sustancialmente en Estados Unidos durante las dos décadas pasadas, la mobilización del plomo almacenado en los huesos representa potencialmente una importante fuente de exposición endógena en mujeres menopáusicas. No obstante, tal movilización no ha sido documentada por estudios prospectivos. La presente discusión se enfoca en algunas de las dificultades metodológicas a se anticipadas en estudios longitudinales de mobilización de plomo específicamente en la menopausia, y los aspectos que necesitan ser considerados cuando se evalúan los resultados de tales estudios. Para evaluar si durante la menopausia el plomo es mobilizado, se requiere de un diseño prospectivo con mediciones repetidas utilizando análisis de fluorescencia de rayos-X para determinar el plomo en hueso y una serie de mediciones de plomo en sangre. Los potenciales confusores y modificadores del efecto también deben tomarse

Leptospirosis is a worldwide zoonotic disease. Risk factors for the disease may vary among countries. This study was conducted to determine the risk factors of leptospirosis among febrile cases. A hospital-based cross-sectional study was conducted among 999 febrile patients admitted to 10 hospitals in northeastern Malaysia, from August 2010 to February 2011. An interviewer-guided proforma sheet on sociodemography, type of occupation and social history data was distributed to all adult patients with fever on admission. Serum sample for leptospirosis was screened by IgM Enzyme-linked Immunosorbent Assay (IgM ELISA) test and confirmed by Microscopic Agglutination Test (MAT). The cut-off point for positive MAT was ≥ 1:400 titer in single acute specimens. Seroprevalence of leptospirosis was 8.4% (95% CI: 6.8, 10.3) (n=84/999) by MAT. Multiple logistic regression analysis showed that the high risk occupation group (OR: 1.95, 95% CI: 1.22, 3.13) (p=0.005) and history of recent recreational activity (OR: 2.36, 95% CI: 1.46, 3.85) (pMalaysia. Identification of high risk occupational group and history of recent recreational activity will help to increase the index of suspicion to diagnose leptospirosis among febrile inpatients due to its mimicking other common febrile illnesses in Malaysia.

In the past decade, malaria control has been successfully implemented in Cambodia, leading to a substantial decrease in reported cases. Wide-spread use of malaria rapid diagnostic tests (RDTs) has revealed a large burden of malaria-negative fever cases, for which no clinical management guidelines exist at peripheral level health facilities. As a first step towards developing such guidelines, a 3-year cross-sectional prospective observational study was designed to investigate the causes of acute malaria-negative febrile illness in Cambodia. From January 2008 to December 2010, 1193 febrile patients and 282 non-febrile individuals were recruited from three health centers in eastern and western Cambodia. Malaria RDTs and routine clinical examination were performed on site by health center staff. Venous samples and nasopharyngeal throat swabs were collected and analysed by molecular diagnostic tests. Blood cultures and blood smears were also taken from all febrile individuals. Molecular testing was applied for malaria parasites, Leptospira, Rickettsia, O. tsutsugamushi, Dengue- and Influenza virus. At least one pathogen was identified in 73.3% (874/1193) of febrile patient samples. Most frequent pathogens detected were P. vivax (33.4%), P. falciparum (26.5%), pathogenic Leptospira (9.4%), Influenza viruses (8.9%), Dengue viruses (6.3%), O. tsutsugamushi (3.9%), Rickettsia (0.2%), and P. knowlesi (0.1%). In the control group, a potential pathogen was identified in 40.4%, most commonly malaria parasites and Leptospira. Clinic-based diagnosis of malaria RDT-negative cases was poorly predictive for pathogen and appropriate treatment. Additional investigations are needed to understand their impact on clinical disease and epidemiology, and the possible role of therapies such as doxycycline, since many of these pathogens were seen in non-febrile subjects.

Respiratory syncytial virus (RSV) infections are associated with clinically significant rate of urinary tract infections (UTIs) in young infants. Previous research investigating RSV infections and UTIs has been performed mainly in infants younger than 2 to 3 months and has not focused on the risk of UTI in infants 3 to 12 months. This study aimed to assess the rate of UTIs in febrile RSV-positive older infants admitted as inpatients and identify predictors of UTI in febrile RSV-positive older infants. This is a retrospective comparative study of febrile RSV-positive infants 0 to 12 months of age admitted to the inpatient pediatric unit of Lincoln Medical and Mental Health Center, Bronx, from September through April 2006 to 2012. Infants 3 to 12 months were considered the cases, and infants 0 to 3 months were the comparative group. The rate of UTIs between the 2 groups was compared. Univariate tests and multiple logistic regression were used to identify demographic/clinical factors associated with UTI in febrile RSV-positive older infants. A total of 414 RSV-positive febrile infants were enrolled including 297 infants 3 to 12 months of age. The rate of UTI in older infants was 6.1% compared with 6.8% in infants younger than 3 months. Positive urinalysis finding was an independent predictor of UTI (P = 0.003) in older infants. All 11 boys with UTI were uncircumcised, and none of the 51 circumcised boys had UTI. Demographic (race, sex, and age) and clinical factors (temperature, white blood cell count, and absolute neutrophil count) were not associated with UTI. Febrile older infants who are RSV positive have a clinically significant rate of UTIs. It seems prudent to examine the urine of these older infants. Positive urinalysis finding was a predictive factor of UTI. Circumcised boys are at a decreased risk of UTI, compared with uncircumcised boys.

Two antibiotics recommended by the guideline of Infectious Diseases Society of America (IDSA) were selected for treatment of febrile neutropenia, and these paired antibiotics were changed periodically three times. The clinical efficacy of each antibiotic was retrospectively evaluated at the end of the final period. There was no significant difference about efficacy rate between two kinds of antibiotics in the same sequential period. However, the efficacy rate has been rising and febrile duration has been shortening by degrees. Only a few drug resistant bacteria were recognized by the surveillance culture during antibiotic cycling. Recently, antibiotic cycling therapy has attracted attention especially in the ICU. However, a clinical study of treatment for febrile neutropenia has not been reported. Our trial suggests that cycling therapy may be useful for febrile neutropenia. However, Some deviation in the patients characteristics of each period may affect the result. It seems that further examination is necessary about usefullness of the cycling therapy for febrile neutropenia.

Full Text Available Patients with hematologic malignancies are susceptible to serious complications due to immunosuppression. Neutropenic-related infection is one of the major causes of morbidity and mortality in this group of diseases. Febrile neutropenia is a common complication of the hematologic neoplasm itself or chemotherapy, and has worse prognosis if prolonged (lasting more than 7 days or severe (neutrophil count below 500 cells per μL. Among the usual sites of infection, we highlight the neutropenic enterocolitis and perianal infection as gastrointestinal complications of greater interest to the colorectal surgeon. Although most cases respond to conservative treatment, a portion of patients will need surgery for complete recovery. Resumo: Os pacientes com neoplasias hematológicas estão sujeitos a uma séria de complicações devido à imunossupressão. Infecção é umas das principais causas de morbidade e mortalidade nesse grupo de doenças.

Febrile seizures are frequent during early childhood, and prolonged (complex) febrile seizures are associated with an increased susceptibility to temporal lobe epilepsy. The pathophysiological consequences of febrile seizures have been extensively studied in rat pups exposed to hyperthermia. The mechanisms that trigger these seizures are unknown, however. A rise in brain pH is known to enhance neuronal excitability. Here we show that hyperthermia causes respiratory alkalosis in the immature brain, with a threshold of 0.2-0.3 pH units for seizure induction. Suppressing alkalosis with 5% ambient CO2 abolished seizures within 20 s. CO2 also prevented two long-term effects of hyperthermic seizures in the hippocampus: the upregulation of the I(h) current and the upregulation of CB1 receptor expression. The effects of hyperthermia were closely mimicked by intraperitoneal injection of bicarbonate. Our work indicates a mechanism for triggering hyperthermic seizures and suggests new strategies in the research and therapy of fever-related epileptic syndromes.

Autism spectrum disorder (ASD) is a heterogeneous disorder characterized not only by deficits in communication and social interactions but also a high rate of co-occurring disorders, including metabolic abnormalities, gastrointestinal and sleep disorders, and seizures. Seizures, when present, interfere with cognitive development and are associated with a higher mortality rate in the ASD population. To determine the relative prevalence of non-febrile seizures in children with idiopathic ASD from multiplex and simplex families compared with the unaffected siblings in a cohort of 610 children with idiopathic ASD and their 160 unaffected siblings, participating in the Autism Genetic Resource Exchange project, the secondary analysis was performed comparing the life-time prevalence of non-febrile seizures. Statistical models to account for non-independence of observations, inherent with the data from multiplex families, were used in assessing potential confounding effects of age, gender, and history of febrile seizures on odds of having non-febrile seizures. The life-time prevalence of non-febrile seizures was 8.2% among children with ASD and 2.5% among their unaffected siblings. In a logistic regression analysis that adjusted for familial clustering, children with ASD had 5.27 (95%CI: 1.51-18.35) times higher odds of having non-febrile seizures compared to their unaffected siblings. In this comparison, age, presence of gastrointestinal dysfunction, and history of febrile seizures were significantly associated with the prevalence of non-febrile seizures. Children with idiopathic ASD are significantly more likely to have non-febrile seizures than their unaffected siblings, suggesting that non-febrile seizures may be ASD-specific. Further studies are needed to determine modifiable risk factors for non-febrile seizures in ASD.

There is a recently well-documented association between childhood epilepsy and earlysymptomaticsyndromeselicitingneurodevelopmentalclinicalexaminations (ESSENCE) including autism spectrum disorder, but the relationship between febrile seizures and ESSENCE is less clear. The Child and Adolescent Twin Study in Sweden (CATSS) is an ongoing population-based study targeting twins born in Sweden since July 1, 1992. Parents of 27,092 twins were interviewed using a validated DSM-IV-based interview for ESSENCE, in connection with the twins' ninth or twelfth birthday. Diagnoses of febrile seizures (n = 492) and epilepsy (n = 282) were based on data from the Swedish National Patient Register. Prevalence of ESSENCE in individuals with febrile seizures and epilepsy was compared with prevalence in the twin population without seizures. The association between febrile seizures and ESSENCE was considered before and after adjustment for epilepsy. Age of diagnosis of febrile seizures and epilepsy was considered as a possible correlate of ESSENCE in febrile seizures and epilepsy. The rate of ESSENCE in febrile seizures and epilepsy was significantly higher than in the total population without seizures (all P epilepsy, a significant association between febrile seizures and autism spectrum disorder, developmental coordination disorder, and intellectual disability remained. Earlier age of onset was associated with all ESSENCE except attention-deficit/hyperactivity disorder in epilepsy but not with ESSENCE in febrile seizures. In a nationally representative sample of twins, there was an increased rate of ESSENCE in childhood epilepsy and in febrile seizures. Febrile seizures alone could occur as a marker for a broader ESSENCE phenotype. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Use of antibiotics is required in febrile neutropenia therapy. The variety choice on the use of antibiotics has increased the role of pharmacoeconomics study to determine the most effective and efficient antibiotic in a specific area. The purpose of this study was to investigate the lowest cost antibiotic between meropenem and ceftazidime that were used as one of febrile neutropenia treatments at one of referral hospitals in West Java province during 2011–2013. This study was a retrospective, observational and analytical study that was performed on February 2014 by collecting medical record data related to febrile neutropenia inpatient who received meropenem or ceftazidime therapy. The result showed that although it was not statistically significant, the total cost for ceftazidime therapy was IDR7,082,523, which was lower than meropenem therapy (IDR11,094,147. Hopefully, this result can assist the health professionals in the management of febrile neutropenia therapy.

Fifty-nine acupoints for febrile disease is recorded in Huangdi Neijing ( Huangdi's Internal Classics ). By analyzing the combination of these acupoints, the writer discovered the acupoint composition and detected their origins from Huangdi's Internal Classics , in which the terms biaoben, qijie and beishu are involved in the theoretic evidence. The writer thought the "fifty-nine acupoints for febrile disease" implied the self-evolution of some acupuncture school in ancient time, which was formed by absorbing the theoretic experiences of the other schools. It is necessary to analyze and interpret the other literatures besides Huangdi's Internal Classics and probably obtain the further reorganization on it.

The purpose of this survey was to study the beliefs, expectations, and satisfaction of Canadian parents regarding fever and the treatment of their febrile children. A survey was developed exploring caregiver beliefs and treatment strategies, as well as expectations and satisfaction with medical care. Some items were modeled after previous studies to allow comparison. Caregivers with febrile children were recruited from 2005 to 2007 at 3 urgent care centers and emergency departments in Edmonton, Canada: a pediatric emergency department (n = 376), an urban urgent care center (n = 227), and a suburban urgent care clinic (n = 173). High and rapidly rising temperature, as well as physical symptoms associated with fever, caused concern in most parents surveyed. Seventy-four percent of parents felt that the elevated temperature from fever was dangerous and 90.3% always try to treat it. Forty degrees Celsius was the most commonly sited threshold for danger. Identifying the cause (80.6%) and seriousness (87.4%) of fever were the most com-mon stressors identified. Caregivers expected to receive information about the child's illness and appropriate treatment. The parents most often wanted information about febrile seizures and the potential dangers of febrile illness. Only 16.7% of caregivers expected anti-biotics. Nearly 92% of subjects were usually satisfied with medical care. Fever phobia continues to be a significant issue for Canadian parents. As a result, they treat fever aggressively and often seek medical attention. Good communication is important for medical staff caring for febrile children and typically leads to satisfied parents.

Objectives Exposure to traffic noise and air pollution is suspected to increase susceptibility to viral infections - the main triggering factor for febrile seizures. No studies have examined these two exposures in relation to febrile seizures. We aimed to investigate whether exposure to road traffic noise and air pollution are associated with risk of febrile seizures in childhood. Methods From our study base of 51 465 singletons from a national birth cohort, we identified 2175 cases with febrile seizures using a nationwide registry. Residential address history from conception to six years of age were found in national registers, and road traffic noise (L den ) and air pollution (NO 2 ) were modeled for all addresses. Analyses were done using Cox proportional hazard model with adjustment for potential confounders, including mutual exposure adjustment. Results An interquartile range (IQR) increase in childhood exposure to road traffic noise and air pollution was associated with an 11% [incidence rate ratio (IRR) 1.11, 95% confidence interval (CI) 1.04-1.19) and 5% (IRR 1.05, 95% CI 1.02-1.07) higher risk for febrile seizures, respectively, after adjustment for potential confounders. Weaker tendencies were seen for pregnancy exposure. In models with mutual exposure adjustment, the estimates were slightly lower, with IRR of 1.08 (95% CI 1.00-1.16) and 1.03 (95% CI 0.99-1.06) per IQR increase in childhood exposure to road traffic noise and air pollution, respectively. Conclusions This study suggests that residential exposure to road traffic noise and air pollution is associated with higher risk for febrile seizures.

Distal ureteral diameter ratio is an objective measure that is prognostic of spontaneous resolution of vesicoureteral reflux. Along with likelihood of resolution, improved identification of children at risk for recurrent febrile urinary tract infections may impact management decisions. We evaluated the usefulness of ureteral diameter ratio as a predictive factor for breakthrough febrile urinary tract infections. Children with primary vesicoureteral reflux and detailed voiding cystourethrogram were identified. Ureteral diameter ratio was computed by measuring largest ureteral diameter within the pelvis and dividing by the distance between L1 and L3 vertebral bodies. Demographics, vesicoureteral reflux grade, laterality, presence/absence of bladder-bowel dysfunction, and ureteral diameter ratio were tested in univariate and multivariable analyses. Primary outcome was breakthrough febrile urinary tract infections. We analyzed 112 girls and 28 boys with a mean ± SD age of 2.5 ± 2.3 years at diagnosis. Vesicoureteral reflux was grade 1 to 2 in 64 patients (45.7%), grade 3 in 50 (35.7%), grade 4 in 16 (11.4%) and grade 5 in 10 (7.2%). Mean ± SD followup was 3.2 ± 2.7 years. A total of 40 children (28.6%) experienced breakthrough febrile urinary tract infections. Ureteral diameter ratio was significantly greater in children with (0.36) vs without (0.25) breakthrough febrile infections (p = 0.004). Controlling for vesicoureteral reflux grade, every 0.1 U increase in ureteral diameter ratio resulted in 1.7 times increased odds of breakthrough infection (95% CI 1.24 to 2.26, p urinary tract infections independent of reflux grade. Ureteral diameter ratio provides valuable prognostic information about risk of recurrent pyelonephritis and may assist with clinical decision-making.

Full Text Available Chikungunya virus (CHIKV re-emerged in Sri Lanka in late 2006 after a 40-year hiatus. We sought to identify and characterize acute chikungunya infection (CHIK in patients presenting with acute undifferentiated febrile illness in unstudied rural and semi-urban southern Sri Lanka in 2007.We enrolled febrile patients ≥ 2 years of age, collected uniform epidemiologic and clinical data, and obtained serum samples for serology, virus isolation, and real-time reverse-transcriptase PCR (RT-PCR. Serology on paired acute and convalescent samples identified acute chikungunya infection in 3.5% (28/797 patients without acute dengue virus (DENV infection, 64.3% (18/28 of which were confirmed by viral isolation and/or real-time RT-PCR. No CHIKV/DENV co-infections were detected among 54 patients with confirmed acute DENV. Sequencing of the E1 coding region of six temporally distinct CHIKV isolates (April through October 2007 showed that all isolates posessed the E1-226A residue and were most closely related to Sri Lankan and Indian isolates from the same time period. Except for more frequent and persistent musculoskeletal symptoms, acute chikungunya infections mimicked DENV and other acute febrile illnesses. Only 12/797 (1.5% patients had serological evidence of past chikungunya infection.Our findings suggest CHIKV is a prominent cause of non-specific acute febrile illness in southern Sri Lanka.

Full Text Available Aim. The study aimed to describe the profile of Filipino febrile neutropenia patients and to determine parameters associated with severe outcomes. Methods. This is a retrospective study of Filipino febrile neutropenia patients admitted to the Philippine General Hospital. Patients were described in terms of clinical presentation and stratified according to the presence or absence of severe outcomes. Prognostic factors were then identified using regression analysis. Results. 115 febrile episodes in 102 patients were identified. Regression analysis yielded prolonged fever >7 days prior to admission (OR 2.43; 95% CI, 0.77–7.74, isolation of a pathogen on cultures (OR 2.69; 95% CI, 1.04–6.98, and nadir absolute neutrophil count (ANC 7 days prior to admission, positive pathogen on cultures, and nadir ANC < 100 during admission predicted severe outcomes, whereas G-CSF use and complete antibiotic therapy were associated with better outcomes. These prognostic variables might be useful in identifying patients that need more intensive treatment and monitoring.

Full Text Available La neutropenia febril constituye una de las principales causas de morbiletalidad en los pacientes con hemopatías malignas; sin embargo, la presentación clínica y evolución de esta complicación varía considerablemente de un paciente a otro. El primer modelo de estratificación de riesgo fue desarrollado por Talcot a partir de elementos clínicos y diferenciaba a los pacientes según el riesgo de presentar complicaciones letales. No obstante, cerca del 10 % de los pacientes catalogados como de bajo riesgo de complicaciones graves requieren tratamiento intrahospitalario. La determinación de algunos reactantes de fase aguda como la proteína C reactiva, las interleucinas 6 y 8 y la procalcitonina, aumentan notablemente la sensibilidad y especificidad de los modelos pronósticos. Las nuevas técnicas imagenológicas y de biología molecular facilitarán el diagnóstico precoz y certero de las infecciones en un futuro cercano. Sin embargo, es necesario desarrollar modelos pronósticos que combinen elementos clínicos y humorales adaptados a las condiciones epidemiológicas de cada centro, para optimizar el tratamiento diferenciado de los enfermos con neutropenia febril.Febrile neutropenia is one of the main causes of mortality in patients presenting with malignant hemopathic disorders; however the clinical and course presentation of this condition differ notably between patients. The first risk stratification model was developed by Talcot from clinical elements and differentiated the patients according the risk of lethal complications. However, around the 10% of patients classed as low risk of severe complications required intrahospital treatment. The determination of some acute phase reactants e.g. reactive C protein, 6 and 8 interleukins, and procalcitonin, increases remarkably the sensitivity and specificity of prognostic model. The new imaging techniques and of molecular biology allow an early and accurate diagnosis of infections in a near

Febrile Infection-Related Epilepsy Syndrome (FIRES): An Overview of Treatment and Recent Patents.

New-onset refractory status epilepticus (NORSE) refers to a clinical presentation in a patient without active epilepsy or other existing relevant neurological disorder, with new onset of refractory status epilepticus in the absence of a clear acute or active structural, metabolic, or toxic cause. Febrile infection-related epilepsy syndrome (FIRES) is a subset of NORSE that requires a febrile infection between 24 hours and 2 weeks prior to the onset of refractory status epilepticus, with or without fever at the onset of status epilepticus, and with no restriction to the age of the patient. The literature on FIRES is scarce. This article reviews the pathophysiology, clinical features, and various treatment modalities in the treatment of FIRES. A Medline/Pubmed search was conducted using Clinical Queries with the key terms "febrile infection-related epilepsy syndrome", "FIRES", "new-onset refractory status epilepticus" and "NORSE". The search strategy included meta-analyses, randomized controlled trials, clinical trials, reviews and pertinent references. Patents were searched using the key term "FIRES", "NORSE" and "febrile epilepsy syndrome" from www.google.com/patents, www.uspto.gov, and www.freepatentsonline.com. FIRES almost invariably begins with a mild nonspecific febrile illness in an otherwise healthy individual. Twenty four hours to two weeks later, seizures begin and quickly become very frequent and worsen, becoming status epilepticus. Seizures can be simple motor, complex partial or secondary generalized. The exact etiology is no known. It is possible that the syndrome is caused by an inflammatory or autoimmune mechanism. Seizures in FIRES are notoriously very difficult to treat. Treatment modalities include, among others, various antiepileptic drugs, ketogenic diet, intravenous corticosteroids, intravenous immunoglobulin, and burst-suppression coma. Outcome is poor; most children are left with significant cognitive disability and refractory epilepsy

Full Text Available Background: Haematopoietic stem cell transplantation is a curative treatment option for many haematological disorders. Infection following haematopoietic stem cell transplantation is one of the major causes of mortality. Aims: To investigate the outcomes of early cessation of empirical antibiotic treatment per protocol in febrile neutropenia patients who have undergone haematopoietic stem cell transplantation at our clinic. Study Design: Descriptive study. Methods: The present study retrospectively evaluated febrile neutropenia attacks in haematopoietic stem cell transplantation recipients during the period June 2014 - January 2015 at our haematopoietic stem cell transplantation clinic. Results: A total of 72 febrile neutropenia attacks were evaluated in 53 patients. In 46 febrile neutropenia attacks, microbiologic cultures revealed positive results. In culture-positive febrile neutropenia episodes a single bacterium was isolated in 32 cases and multiple strains were isolated in 14. In 15 patients, empirical antibiotic therapy was discontinued after 72 hours. These patients were clinically stable, without evident focus of infection and had negative culture results. Only 4 recurrent episodes were observed (27% after cessation of antibiotherapy. No patient died as a result of recurrent infection. The 30-day and 100-day post-transplantation mortality rates of patients with febrile neutropenia episodes were 11.3% (6/53 and 3.8% (2/53, respectively. Infection-related 30-day and 100-day mortality rates were 7.5% (4/53 and 0% (0/53, respectively. Conclusion: The main message of our study is that early cessation of empirical antibiotherapy seems to be feasible in eligible patients without increasing febrile neutropenia mortality rates

The pathogenesis of febrile status epilepticus is poorly understood, but prior studies have suggested an association with temporal lobe abnormalities, including hippocampal malrotation. We used a quantitative morphometric method to assess the association between temporal lobe morphology and febrile status epilepticus. Brain MR imaging was performed in children presenting with febrile status epilepticus and control subjects as part of the Consequences of Prolonged Febrile Seizures in Childhood study. Medial temporal lobe morphologic parameters were measured manually, including the distance of the hippocampus from the midline, hippocampal height:width ratio, hippocampal angle, collateral sulcus angle, and width of the temporal horn. Temporal lobe morphologic parameters were correlated with the presence of visual hippocampal malrotation; the strongest association was with left temporal horn width (P status epilepticus, encompassing both the right and left sides. This association was statistically strongest in the right temporal lobe, whereas hippocampal malrotation was almost exclusively left-sided in this cohort. The association between temporal lobe measurements and febrile status epilepticus persisted when the analysis was restricted to cases with visually normal imaging findings without hippocampal malrotation or other visually apparent abnormalities. Several component morphologic features of hippocampal malrotation are independently associated with febrile status epilepticus, even when complete hippocampal malrotation is absent. Unexpectedly, this association predominantly involves the right temporal lobe. These findings suggest that a spectrum of bilateral temporal lobe anomalies are associated with febrile status epilepticus in children. Hippocampal malrotation may represent a visually apparent subset of this spectrum. © 2016 by American Journal of Neuroradiology.

Este estudio se realizó entre mayo del 2010 y diciembre del 2011. Se seleccionaron 29 pacientes al azar entre 51 y 74 años de edad con fototipos II a IV, a los que se les inyectó AH para rejuvenecer las manos. La cantidad de AH inyectada en cada mano fue de 1 a 2 ml. Se realizaron controles sistemáticos en la 2ª semana, en los meses 1º, 3º, 6º, 9º y 12º. Se tuvieron en cuenta las complicaciones en cada paciente en todos los controles. En el primer control, en la 2ª semana, junto al examen clínico se practicó examen ecográfico a fin de determinar si sería necesaria una segunda inyección de AH. En cada uno de los controles los pacientes contestaron a un formulario para indagar sobre su grado de satisfacción con el tratamiento. Solo 1 paciente presentó edema y 3 tuvieron equimosis leve; 2 pacientes manifestaron dolor leve con las inyecciones y 2 requirieron una segunda inyección tras la valoración en la 2ª semana. La satisfacción de los pacientes en los controles superó la valoración clínica y fotográfica. En nuestra opinión, el rejuvenecimiento de las manos con este tipo de AH de grandes partículas tiene una baja tasa de complicaciones y es bien tolerado, con un alto grado de satisfacción por parte de los pacientes y una notable mejoría de los parámetros estudiados: arrugas, aspecto de la atrofia dérmica y subcutánea y disminución de los relieves óseos, tendinosos y venosos.

Full Text Available Febrile seizure is the most common convulsive disorder in children and different studies reported controversial results about the association between this disorder and iron deficiency. In some studies, iron level in children with febrile seizure is higher than control and in some reports it is less than the control group. So, we systematically reviewed all the studies in this field and analyzed their findings using meta-analysis methods. This review and meta-analysis was conducted by iron and fever keywords on articles published in the databases PubMed, Google Scholar and Federated search of medical digital library that includes a variety of international databases. All articles dated at the end of March 2012 were studied. Case-control studies were selected and quality assessment of studies were surveyed by STROB criteria and information requirements, including the status of iron deficiency anemia, iron levels and ferritin level of eligible studies were extracted and analyzed by Comprehensive Meta-Analysis Version 2.0 software and the Forest and Funnel chart was drawn. Finally 11 studies included 1357 children with febrile seizure and 1347 children in the control group were evaluated. The odds ratio of iron deficiency anemia in children with febrile seizure in comparison to the control group was 1.27 (OR = 1.27, CI95%: 1.03 -1.56. Ferritin level was not significant between the two groups (p=0.08, but the iron level in the two groups was significant (p=0.000. Iron deficiency is considered as a risk factor in the incidence of febrile seizure and interventional studies can be helpful to confirm this hypothesis.

Nnaji, G A; Ikechebelu, J I

2007-11-01

The object of this study was to evaluate the sensitivity and specificity of reported febrile illness in predicting malaria in pregnant women at booking in NAUTH, Nnewi. This was a case control prospective survey using a structured questionnaire to collect data from pregnant women attending antenatal clinic of Nnamdi Azikiwe University Teaching Hospital between April and September 2001. Peripheral blood smears were examined in 420 pregnant women during their first antenatal visit. This study showed that 57.4% of parasitaemic pregnant women and 54% of aparasitaemic pregnant women reported fever before their first antenatal visit. The sensitivity and specificity of reported febrile illness in predicting malaria were 57.4% and 46%, respectively. However, the predictive value of a positive test was as high as 80.25%, while it was only 22% for the predictive value of a negative test. The efficiency of reported febrile illness as a screening device was 55%. Reliance on reported febrile illness will not be adequate to identify parasitaemic pregnant women because many of those with heavy placental parasitisation may not report fever. This justifies the place of the intermittent presumptive therapy using sulphadoxine-pyrimethamine in pregnant women living in malaria endemic areas such as sub-Saharan Africa.

Full Text Available OBJECTIVE: In a large population-based cohort in Denmark to examine if maternal use of antibiotics during pregnancy, as a marker of infection, increases the risk of febrile seizures in childhood in a large population-based cohort in Denmark. METHODS: All live-born singletons born in Denmark between January 1, 1996 and September 25, 2004 and who were alive on the 90(th day of life were identified from the Danish National Birth Registry. Diagnoses of febrile seizures were obtained from the Danish National Hospital Register and maternal use of antibiotics was obtained from the National Register of Medicinal Product Statistics. Hazard ratios (HR and 95% confidence intervals (95% CI were estimated by Cox proportional hazard regression models. RESULTS: We followed 551,518 singletons for up to 5 years and identified a total of 21,779 children with a diagnosis of febrile seizures. Slightly increased hazard ratios were observed among most exposure groups when compared to the unexposed group, ex. HR 1.08 95% CI: 1.05-1.11 for use of any systemic antibiotic during pregnancy. CONCLUSION: We found weak associations between the use of pharmacologically different antibiotics during pregnancy and febrile seizures in early childhood which may indicate that some infections, or causes or effects of infections, during pregnancy could affect the fetal brain and induce susceptibility to febrile seizures.

Results and Conclusion : Out of these, 70% had primary CNS infection as the etiology. A total of 33% patients had meningitis, 29.9% had evidence of meningoencephalitis, and 12.7% were diagnosed as sepsis-associated encephalopathy. These were followed by cerebral malaria, leptospirosis, and brain abscess as the cause of febrile encephalopathy in adults. Among the noninfectious causes, acute disseminated encephalomyelitis, cortical venous thrombosis, and neuroleptic malignant syndrome were documented in 2.36% each. In 11% of the patients, the final diagnosis could not be made in spite of the extensive investigations. Our study demonstrates that acute febrile encephalopathy in adults is a heterogeneous syndrome with primary CNS infections being the commonest

Full Text Available Convulsions triggered by fever are the most common type of seizures in childhood, and 20% to 30% of them have recurrence. The prophylactic treatment is still controversial, so we performed a systematic review to find out the effectiveness of continuous phenobarbital and intermittent diazepam compared to placebo for febrile seizure recurrence. METHOD: Only randomized, double-blind, placebo-controlled trials were analyzed. The recurrence of febrile seizure was assessed for each drug. RESULTS: Ten eligible clinical trials were included. Febrile seizure recurrence was smaller in children treated with diazepam or phenobarbital than in placebo group. Prophylaxis with either phenobarbital or diazepam reduces recurrences of febrile seizures. The studies were clinical, methodological, and statistically heterogeneous. CONCLUSION: The effectiveness of phenobarbital and diazepam could not be demonstrated because clinical trials were heterogeneous, and the recommendation for treatment recurrence should rely upon the experience of the assistant physician yet.

Febrile adults are usually not tested for acute HIV-1 infection (AHI) in Africa. We assessed a strategy to diagnose AHI among young adult patients seeking care. Young adults (defined as a positive p24 antigen test, and subsequent seroconversion or RNA detection. Febrile patients evaluated for AHI were also screened for malaria using a rapid test, with PCR confirmation of positives. In 3602 adults seeking care, overall HIV-1 prevalence was 3.9%: 7.6% (68/897) among patients meeting AHI criteria vs. 2.6% (71/2705) among those who did not (P young febrile adults seeking care. An AHI detection strategy targeting young febrile adults seeking care at pharmacies and health facilities is feasible and should be considered as an HIV-prevention strategy in high-transmission settings.

The current roll-out of rapid diagnostic tests (RDTs) in many endemic countries has resulted in the reporting of fewer cases of malaria-attributed illnesses. However, lack of knowledge of the prevalence of other febrile illnesses and affordable diagnostic tests means that febrile patients are not managed optimally. This study assessed the prevalence of commonly treatable or preventable febrile illnesses in children between 6 months and 15 years using rapid diagnostic tests at the point-of-care. Febrile children were enrolled between February-April 2014 at a health facility after obtaining informed consent from parent. Eligible participants were aged 6 months-15 years with a history of fever in the last 24 h or axillary temperature ≥38 °C at consultation. All participants were tested using RDTs for malaria, typhoid, toxoplasmosis and rubella. Malaria parasites were further identified by microscopy and PCR. Clinical and household characteristics were recorded and association with pathogens determined. Of the 315 children enrolled, the mean age was 5.8 ± 3.8 years. Stomach pain (41.2 %) was the most reported symptom. Prior to attending the health facility, 70.8 % had taken antipyretics, 27.9 % antimalarials, 11.4 % antibiotics and 13.3 % antifungal drugs. Among 315 children with fever, based on RDTs, 56.8 % were infected with malaria, 4.4 % with typhoid, 3.2 % with acute toxoplasmosis, and 1.3 % with rubella (all positive for rubella were in the same family and not vaccinated). All non-malarial infections were co-infections and approximately 30 % of the fever cases went un-diagnosed. Malaria prevalence by microscopy and PCR was 43.4 and 70.2 % respectively. The sensitivity and specificity of RDTs for the diagnosis of malaria were 75.98 and 100 % respectively, with 0.73 measurement agreement between RDTs and microscopy while that of RDT and PCR were 81 and 100 % respectively with a K value of 0.72.

We enrolled consecutive febrile admissions to two hospitals in Moshi, Tanzania. Confirmed leptospirosis was defined as a ≥ 4-fold increase in microscopic agglutination test (MAT) titer; probable leptospirosis as reciprocal MAT titer ≥ 800; and exposure to pathogenic leptospires as titer ≥ 100. Among 870 patients enrolled in the study, 453 (52.1%) had paired sera available, and 40 (8.8%) of these met the definition for confirmed leptospirosis. Of 832 patients with ≥ 1 serum sample available, 30 (3.6%) had probable leptospirosis and an additional 277 (33.3%) had evidence of exposure to pathogenic leptospires. Among those with leptospirosis the most common clinical diagnoses were malaria in 31 (44.3%) and pneumonia in 18 (25.7%). Leptospirosis was associated with living in a rural area (odds ratio [OR] 3.4, P < 0.001). Among those with confirmed leptospirosis, the predominant reactive serogroups were Mini and Australis. Leptospirosis is a major yet underdiagnosed cause of febrile illness in northern Tanzania, where it appears to be endemic. PMID:21813847

Acute and convalescent serum samples were collected from febrile inpatients identified at two hospitals in Moshi, Tanzania. Confirmed brucellosis was defined as a positive blood culture or a ≥ 4-fold increase in microagglutination test titer, and probable brucellosis was defined as a single reciprocal titer ≥ 160. Among 870 participants enrolled in the study, 455 (52.3%) had paired sera available. Of these, 16 (3.5%) met criteria for confirmed brucellosis. Of 830 participants with ≥ 1 serum sample, 4 (0.5%) met criteria for probable brucellosis. Brucellosis was associated with increased median age (P = 0.024), leukopenia (odds ratio [OR] 7.8, P = 0.005), thrombocytopenia (OR 3.9, P = 0.018), and evidence of other zoonoses (OR 3.2, P = 0.026). Brucellosis was never diagnosed clinically, and although all participants with brucellosis received antibacterials or antimalarials in the hospital, no participant received standard brucellosis treatment. Brucellosis is an underdiagnosed and untreated cause of febrile disease among hospitalized adult and pediatric patients in northern Tanzania. PMID:23091197

In sub-Saharan Africa, malaria is frequently overdiagnosed as the cause of an undifferentiated febrile illness, whereas arboviral illnesses are presumed to be underdiagnosed. Sera from 385 febrile Kenyan children, who presented to 1 of 4 clinical sites, were tested using microscopy and real-time molecular assays for dengue virus (DENV), chikungunya virus (CHIKV), malaria, and Leptospira . Malaria was the primary clinical diagnosis for 254 patients, and an arboviral infection (DENV or CHIKV) was the primary diagnosis for 93 patients. In total, 158 patients (41.0%) had malaria and 32 patients (8.3%) had CHIKV infections. Compared with real-time polymerase chain reaction, microscopy demonstrated a percent positive agreement of 49.7%. The percentage of malaria cases detected by microscopy varied significantly between clinical sites. Arboviral infections were the clinical diagnosis for patients on the Indian Ocean coast (91 of 238, 38.2%) significantly more often than patients in the Lake Victoria region (2 of 145, 1.4%; P < .001). However, detection of CHIKV infections was significantly higher in the Lake Victoria region (19 of 145 [13.1%] vs 13 of 239 [5.4%]; P = .012). The clinical diagnosis of patients with an acute febrile illness, even when aided by microscopy, remains inaccurate in malaria-endemic areas, contributing to inappropriate management decisions.

Infusional β-lactam antibiotics in febrile neutropenia: has the time come?

Abbott, Iain J; Roberts, Jason A

2012-12-01

Febrile neutropenia presents a clinical challenge in which timely and appropriate antibiotic exposure is crucial. In the context of altered pharmacokinetics and rising bacterial resistance, standard antibiotic doses are unlikely to be sufficient. This review explores the potential utility of altered dosing approaches of β-lactam antibiotics to optimize treatment in febrile neutropenia. There is a dynamic relationship between the antibiotic, the infecting pathogen, and the host. Great advancements have been made in the understanding of the pharmacokinetic changes in critical illness and the pharmacodynamic relationships of antibiotics in these settings. Antibiotic treatment in febrile neutropenia is becoming increasingly difficult. Patients are of higher acuity, receive more intensive chemotherapy regimens leading to prolonged neutropenia, and are often exposed to multiple antibiotic courses. These patients display significant variability in antibiotic clearances and increases in volume of distribution compared with standard ward-based patients. Rising antibiotic resistance and a lack of new antibiotics in production have prompted alternative dosing strategies based on pharmacokinetic/pharmacodynamic data, such as extended or continuous infusions of β-lactam antibiotics, to maximize the likelihood of treatment success. A definitive study that describes a mortality benefit of such dosing regimens remains elusive and the theoretical advantages require testing in well designed clinical trials.

Full Text Available Em razão da urgência de se decidir por um tratamento clínico ou por uma intervenção cirúrgica imediata, o estudo da colestase neonatal prolongada envolve dois objetivos básicos: o diagnóstico diferencial entre atresia biliar e hepatite neonatal e a pesquisa dos agentes etiológicos associados. Desta maneira, através de estudo prospectivo desenvolvido na década de 1970, foram avaliadas 77 crianças portadoras de colestase neonatal prolongada para estabelecer o diagnóstico diferencial entre atresia biliar e hepatite neonatal e, numa segunda fase, 108 crianças, visando esclarecer a etiopatogenia da colestase neonatal prolongada. Os resultados do diagnóstico diferencial revelaram que, dos 18 atributos avaliados, apenas oito mostraram-se bons indicadores de atresia biliar, em ordem decrescente: ductos proliferados (espaço-porta, fibrose (espaço-porta, colestase (espaço-porta, cor das fezes -- acolia, hepatomegalia, colestase canalicular (lóbulo, infiltrado (espaço-porta, células gigantes (lóbulo. Estes oito atributos foram então compostos, mediante uma ponderação, em um único indicador de grande poder discriminativo, capaz de decidir o diagnóstico diferencial em 99% dos casos. Quanto à etiopatogenia, registrou-se: vírus rubéola 0%, vírus herpes simples 0%, listeriose 0%, citomegalovirose 2,2%, vírus hepatite B 2,4%, toxoplasmose 2,8%, deficiência de alfa-1-antitripsina 13,1%, sífilis 21,1 %, auto-anticorpos hepáticos 58,4%. O trabalho desenvolvido mostra que as 8 variáveis mais decisivas, como indicadoras diferenciais entre atresia biliar e hepatite neonatal, permanecem como índices fundamentais, auxiliando, em conjunto com novos métodos diagnósticos, na composição de uma estratégia multifatorial cada vez menos invasiva e mais precisa. O estudo da etiopatogenia, dependente das condições epidemiológicas locais e da época, com a introdução de novos métodos diagnósticos, torna-se atualmente cada vez mais

The effect of low ambient temperature on the febrile responses of rats to semi-purified human endogenous pyrogen.

1985-01-01

The febrile responses of Sprague-Dawley rats to semi-purified human endogenous pyrogen were studied at a thermoneutral ambient temperature (26 degrees C) and in the cold (3 degrees C). It was found that while rats developed typical monophasic febrile responses at thermoneutrality, febrile responses were absent in the cold-exposed rats. Experiments were conducted to determine whether this lack of febrile responses in cold-exposed rats was due to an inability of these animals to generate or retain heat in the cold. Thermogenesis and vasoconstriction were stimulated in cold-exposed rats by selectively cooling the hypothalamus, using chronically implanted thermodes. It was shown that, using this stimulus, metabolic rate could be increased by more than 50 percent and body temperature could be driven up at a rate of 5 degrees C/hour in rats exposed to the cold. Therefore, it was concluded that the lack of febrile responses of cold-exposed rats to pyrogen is in no way due to a physical or physiological inability to retain heat. Instead, it appears that in some manner cold exposure suppresses the sensitivity or responsiveness of the rat to pyrogenic stimuli.

Current guidelines do not recommend G-CSF for patients with risk factors for neutropenia. One-hundred patients undergoing chemotherapy were randomized to treatment with G-CSF at 5 Kg/kg for established febrile neutropenia (ANC <1000/microl) (Group A) or G-CSF at 263 Kg/day if ANC was 1500/microl or less on the day of the expected nadir, with the duration of treatment determined by the severity of neutropenia (Group B). The number of doses of G-CSF was similar in the two groups. There were 34 cases of febrile neutropenia in Group A, but none in Group B (p=0.0001). Hospital admission for febrile neutropenia, antibiotic use and delays in chemotherapy were all significantly more common in Group A. Total direct costs were estimated to be 66, 646 for Group A and 47, 119 for Group B. Tailoring treatment does not increase G-CSF use, but significantly reduces febrile neutropenia and treatment delays and lowers direct costs.

IMPORTANCE Young febrile infants are at substantial risk of serious bacterial infections; however, the current culture-based diagnosis has limitations. Analysis of host expression patterns (“RNA biosignatures”) in response to infections may provide an alternative diagnostic approach. OBJECTIVE To assess whether RNA biosignatures can distinguish febrile infants aged 60 days or younger with and without serious bacterial infections. DESIGN, SETTING, AND PARTICIPANTS Prospective observational study involving a convenience sample of febrile infants 60 days or younger evaluated for fever (temperature >38° C) in 22 emergency departments from December 2008 to December 2010 who underwent laboratory evaluations including blood cultures. A random sample of infants with and without bacterial infections was selected for RNA biosignature analysis. Afebrile healthy infants served as controls. Blood samples were collected for cultures and RNA biosignatures. Bioinformatics tools were applied to define RNA biosignatures to classify febrile infants by infection type. EXPOSURE RNA biosignatures compared with cultures for discriminating febrile infants with and without bacterial infections and infants with bacteremia from those without bacterial infections. MAIN OUTCOMES AND MEASURES Bacterial infection confirmed by culture. Performance of RNA biosignatures was compared with routine laboratory screening tests and Yale Observation Scale (YOS) scores. RESULTS Of 1883 febrile infants (median age, 37 days; 55.7%boys), RNA biosignatures were measured in 279 randomly selected infants (89 with bacterial infections—including 32 with bacteremia and 15 with urinary tract infections—and 190 without bacterial infections), and 19 afebrile healthy infants. Sixty-six classifier genes were identified that distinguished infants with and without bacterial infections in the test set with 87%(95%CI, 73%-95%) sensitivity and 89% (95%CI, 81%-93%) specificity. Ten classifier genes distinguished

To compare tympanic membrane temperature and rectal temperature in febrile pediatric patients. Sixty febrile children were enrolled as continuous enrollment at initial triage. Two readings of ear temperature were taken in each child with Thermoscan infrared thermometer. Rectal temperature was recorded by a digital electronic thermometer. Comparison of both the techniques was done and co-relation co-efficients calculated. Parental preference for both techniques was assessed. It was observed that mean ear temperature was 38.9+/-0.90 C and that for rectal temperature was 38.8+/-0.80 degrees C. The correlation coefficient between the two was 0.994 (p rays emitted from the surface of tympanic membrane. Ear temperatures correlates well with rectal temperatures which have long been considered as "core" temperatures. Parents prefer the technique of ear thermometry which is quick (2 sec), safe and non-invasive and patient resistance for this is also less. A non-invasive, non-mucous device which is accurate over a wide range of temperature could be very useful.

Malaria transmission is spatially heterogeneous. This reduces the efficacy of control strategies, but focusing control strategies on clusters or 'hotspots' of transmission may be highly effective. Among 1500 homesteads in coastal Kenya we calculated (a) the fraction of febrile children with positive malaria smears per homestead, and (b) the mean age of children with malaria per homestead. These two measures were inversely correlated, indicating that children in homesteads at higher transmission acquire immunity more rapidly. This inverse correlation increased gradually with increasing spatial scale of analysis, and hotspots of febrile malaria were identified at every scale. We found hotspots within hotspots, down to the level of an individual homestead. Febrile malaria hotspots were temporally unstable, but 4 km radius hotspots could be targeted for 1 month following 1 month periods of surveillance.DOI: http://dx.doi.org/10.7554/eLife.02130.001.

Febrile illness diagnostics and the malaria-industrial complex: a socio-environmental perspective

Directory of Open Access Journals (Sweden)

2016-11-01

Full Text Available Abstract Background Global prioritization of single-disease eradication programs over improvements to basic diagnostic capacity in the Global South have left the world unprepared for epidemics of chikungunya, Ebola, Zika, and whatever lies on the horizon. The medical establishment is slowly realizing that in many parts of sub-Saharan Africa (SSA, particularly urban areas, up to a third of patients suffering from acute fever do not receive a correct diagnosis of their infection. Main body Malaria is the most common diagnosis for febrile patients in low-resource health care settings, and malaria misdiagnosis has soared due to the institutionalization of malaria as the primary febrile illness of SSA by international development organizations and national malaria control programs. This has inadvertently created a “malaria-industrial complex” and historically obstructed our complete understanding of the continent’s complex communicable disease epidemiology, which is currently dominated by a mélange of undiagnosed febrile illnesses. We synthesize interdisciplinary literature from Ghana to highlight the complexity of communicable disease care in SSA from biomedical, social, and environmental perspectives, and suggest a way forward. Conclusion A socio-environmental approach to acute febrile illness etiology, diagnostics, and management would lead to substantial health gains in Africa, including more efficient malaria control. Such an approach would also improve global preparedness for future epidemics of emerging pathogens such as chikungunya, Ebola, and Zika, all of which originated in SSA with limited baseline understanding of their epidemiology despite clinical recognition of these viruses for many decades. Impending ACT resistance, new vaccine delays, and climate change all beckon our attention to proper diagnosis of fevers in order to maximize limited health care resources.

Background Arthropod-borne viruses (arboviruses) are among the most common agents of human febrile illness worldwide and the most important emerging pathogens, causing multiple notable epidemics of human disease over recent decades. Despite the public health relevance, little is know about the geographic distribution, relative impact, and risk factors for arbovirus infection in many regions of the world. Our objectives were to describe the arboviruses associated with acute undifferentiated febrile illness in participating clinics in four countries in South America and to provide detailed epidemiological analysis of arbovirus infection in Iquitos, Peru, where more extensive monitoring was conducted. Methodology/Findings A clinic-based syndromic surveillance system was implemented in 13 locations in Ecuador, Peru, Bolivia, and Paraguay. Serum samples and demographic information were collected from febrile participants reporting to local health clinics or hospitals. Acute-phase sera were tested for viral infection by immunofluorescence assay or RT-PCR, while acute- and convalescent-phase sera were tested for pathogen-specific IgM by ELISA. Between May 2000 and December 2007, 20,880 participants were included in the study, with evidence for recent arbovirus infection detected for 6,793 (32.5%). Dengue viruses (Flavivirus) were the most common arbovirus infections, totaling 26.0% of febrile episodes, with DENV-3 as the most common serotype. Alphavirus (Venezuelan equine encephalitis virus [VEEV] and Mayaro virus [MAYV]) and Orthobunyavirus (Oropouche virus [OROV], Group C viruses, and Guaroa virus) infections were both observed in approximately 3% of febrile episodes. In Iquitos, risk factors for VEEV and MAYV infection included being male and reporting to a rural (vs urban) clinic. In contrast, OROV infection was similar between sexes and type of clinic. Conclusions/Significance Our data provide a better understanding of the geographic range of arboviruses in South

DMSA study is an established method for the assessment of renal sequelae after acute pyelonephritis related to febrile urinary tract infection (UTI). However, at the moment is not established if the DMSA study performed during the acute UTI has any prognostic value for outcome assessment. Objectives: to assess the usefulness of DMSA study performed during febrile UTI as predictor of patient outcome. Methods: One hundred-fifty-two children (74 boys) with mean age 20 months (range 1m-12 y) with first febrile UTI were studied by DMSA planar scintigraphy during the acute illness period (first 5 days). All patients had positive grown bacillus in urine (78% E. coli, 8% P. mirabilis), and all followed the same antibiotic treatment. After acute UTI all patients were explored by voiding cysto urethrography for diagnosis of vesicoureteral reflux (VUR). Fifty-seven patients who had an abnormal DMSA study, VUR, or recurrent UTI underwent a DMSA control study (mean 8m after UTI). Results: DMSA study during febrile UTI was normal in 112 children (74%). In 95 of these children, follow-up DMSA studies were not performed due to a good clinical outcome (no VUR, no recurrent UTI). In the remaining 17 patients, follow-up DMSA studies were normal as well. Forty children (26%), who presented focal or diffuse cortical lesions during acute UTI, underwent a DMSA control study. Twenty-six of them presented a normal control DMSA, and 14 (9% of all patients) presented cortical lesions, 10 associated with a high-grade VUR. Fifty-seven children were followed by control DMSA, and no significant correlation between initial and follow-up study was found (κ= 0.250, p<0.007). Conclusion: These results indicate that DMSA study performed during febrile UTI may not be useful as predictor of patient outcome. Voiding cysto urethrography and control DMSA study seem to be more useful to select patients at risk of development of chronic cortical lesions

The goals were to describe the (1) frequency of sepsis evaluation and empiric antibiotic treatment, (2) clinical predictors of management, and (3) serious bacterial illness frequency for febrile infants with clinically diagnosed bronchiolitis seen in office settings. The Pediatric Research in Office Settings network conducted a prospective cohort study of 3066 febrile infants (or=38 degrees C) in 219 practices in 44 states. We compared the frequency of sepsis evaluation, parenteral antibiotic treatment, and serious bacterial illness in infants with and without clinically diagnosed bronchiolitis. We identified predictors of sepsis evaluation and parenteral antibiotic treatment in infants with bronchiolitis by using logistic regression models. Practitioners were less likely to perform a complete sepsis evaluation, urine testing, and cerebrospinal fluid culture and to administer parenteral antibiotic treatment for infants with bronchiolitis, compared with those without bronchiolitis. Significant predictors of sepsis evaluation in infants with bronchiolitis included younger age, higher maximal temperature, and respiratory syncytial virus testing. Predictors of parenteral antibiotic use included initial ill appearance, age of urinary tract infection (n = 167). In office settings, serious bacterial illness in young febrile infants with clinically diagnosed bronchiolitis is uncommon. Limited testing for bacterial infections seems to be an appropriate management strategy.

Chemotherapy induced febrile neutropenia predisposes patients to life threatening infections. We aimed to determine the causative microorganisms, infection focus and antibiotic treatment success in febrile neutropenic children with leukemia. A total of 136 febrile neutropenic episodes in 48 leukemic children were reviewed retrospectively from records. Among 136 febrile neutropenic episodes, 68 (50%) episodes were microbiologically documented. Methicillin sensitive coagulase (-) Staphylococcus aureus were the most common isolates from hemoculture (20.5%). The most frequently documented infection focus was mucositis (31.9%). Ceftazidime plus amikacin was the most commonly used antimicrobial treatment for the empirical therapy (52.9%). The overall response rates were 70.5%, 86.9%, and 66.6% of first line, second line and third line therapies, respectively. The spectrum of isolates among febrile neutropenic children in our hematology clinic appears to be gram positive pathogens which are the most common agents. Therefore the, documentation of the flora in each unit could help to decide appropriate empirical therapy which is life saving.

Urinary tract infection (UTI) screening in febrile young children can be painful and time consuming. We implemented a screening protocol for UTI in a high-volume pediatric emergency department (ED) to reduce urethral catheterization, limiting catheterization to children with positive screens from urine bag specimens. This quality-improvement initiative was implemented using 3 Plan-Do-Study-Act cycles, beginning with a small test of the proposed change in 1 ED area. To ensure appropriate patients received timely screening, care teams discussed patient risk factors and created patient-specific, appropriate procedures. The intervention was extended to the entire ED after providing education. Finally, visual cues were added into the electronic health record, and nursing scripts were developed to enlist family participation. A time-series design was used to study the impact of the 6-month intervention by using a p-chart to determine special cause variation. The primary outcome measure for the study was defined as the catheterization rate in febrile children ages 6 to 24 months. The ED reduced catheterization rates among febrile young children from 63% to UTIs among those followed within the hospital's network. A 2-step less-invasive process for screening febrile young children for UTI can be instituted in a high-volume ED without increasing length of stay or missing cases of UTI.

Full Text Available Brucellosis is a systemic disease in which all kind of tissues and organs can be affected. Brucellosis may present with different symptoms and symptoms are non-specific. A broad spectrum of clinical manifestations can be seen, therefore diagnosis can be difficult. Cutaneous complications and febrile neutropenia have been rarely reported. Here, a rare brucellosis case was reported that he applied with fever, skin eruption and neutropenia. We emphasized that especially in endemic areas brucellosis should always be kept on mind in the differential diagnosis of patient with skin eruption and febril neutropenia.J Microbiol Infect Dis 2014;4(1: 39-41

Full Text Available Febrile seizure is one of the most common neurological problems during childhood. The etiology and pathogenesis of febrile seizure remain unknown. However, several factors such as vitamin B6 deficiency, electrolyte disturbances, and reduction in serum zinc, selenium, magnesium levels, and low gamma - aminobutyric acid (GABA levels are thought to play a role in the pathogenesis of febrile seizure. The present study included twenty children from 10 families, 11 were male and 9 were female. Each family has at least 2 members with a history of febrile convulsion. All cases were subjected to the following: Determination of serum levels of copper, zinc, magnesium, selenium level in serum, and plasma level of γ-aminobytaric acid (GABA. Serum levels of selenium and GABA were statistically significantly low in comparison with controls. Serum copper was statistically significantly higher in cases than controls, while serum zinc showed no significant changes in the cases of febrile convulsion compared with the control group. The mean Zn level in the serum of febrile convulsion was found to be at lower level than in the control group. The serum magnesium was significantly low in cases than controls. The logistic regression model in our study shows that Selenium and Magnesium have protective effects, while Copper has causative effect.

Outbreaks of transmissible respiratory infection are suspected to have significant effects on the health of pediatric and geriatric patients. The objective was to assess the impact of the Middle East respiratory syndrome (MERS) outbreak on the use of emergency resources. An ecologic analysis of emergency department (ED) records between September and December 2015, was performed. Data was obtained from the National Emergency Department Information System database for Korea. All demographic and diagnostic data from patients presenting with febrile symptoms as a main complaint were collected. The data were compared to the equivalent period in the three years preceding the MERS outbreak in Korea. Following the MERS outbreak, there was an increase in overall ED visits by febrile patients and the proportion of visits by febrile patients, relative to total ED attendances. This effect was more prominent in the children under five years. The duration of the chief complaint before ED arrival and the length of ED stay were significantly increased among younger pediatric patients. Decreased body temperature on arrival was observed in younger pediatric patients. MERS outbreak appears to have had a significant effects on ED use by febrile patients. The use of emergency care services by pediatric patients makes them more vulnerable to an outbreak of a transmissable disease. An effective strategy to control emergency center visits by non-urgent febrile patients and provide proper medical services is urgently needed.

Bart C Jongbloets

Full Text Available Febrile seizures are the most prevalent type of seizures among children up to 5 years of age (2-4% of Western-European children. Complex febrile seizures are associated with an increased risk to develop temporal lobe epilepsy. To investigate short- and long-term effects of experimental febrile seizures (eFS, we induced eFS in highly febrile convulsion-susceptible C57BL/6J mice at post-natal day 10 by exposure to hyperthermia (HT and compared them to normotherm-exposed (NT mice. We detected structural re-organization in the hippocampus 14 days after eFS. To identify molecular candidates, which entrain this structural re-organization, we investigated temporal changes in mRNA expression profiles eFS 1 hour to 56 days after eFS. We identified 931 regulated genes and profiled several candidates using in situ hybridization and histology at 3 and 14 days after eFS. This is the first study to report genome-wide transcriptome analysis after eFS in mice. We identify temporal regulation of multiple processes, such as stress-, immune- and inflammatory responses, glia activation, glutamate-glutamine cycle and myelination. Identification of the short- and long-term changes after eFS is important to elucidate the mechanisms contributing to epileptogenesis.

Febrile neutropenia is a frequent adverse event experienced by people with cancer who are undergoing chemotherapy, and is a potentially life-threatening situation. The current treatment is supportive care plus antibiotics. Colony-stimulating factors (CSFs), such as granulocyte-CSF (G-CSF) and granulocyte-macrophage CSF (GM-CSF), are cytokines that stimulate and accelerate the production of one or more cell lines in the bone marrow. Clinical trials have addressed the question of whether the addition of a CSF to antibiotics could improve outcomes in individuals diagnosed with febrile neutropenia. However, the results of these trials are conflicting. To evaluate the safety and efficacy of adding G-CSF or GM-CSF to standard treatment (antibiotics) when treating chemotherapy-induced febrile neutropenia in individuals diagnosed with cancer. We conducted the search in March 2014 and covered the major electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, LILACS, and SCI. We contacted experts in hematology and oncology and also scanned the citations from the relevant articles. We searched for randomized controlled trials (RCTs) that compared CSF plus antibiotics versus antibiotics alone for the treatment of chemotherapy-induced febrile neutropenia in adults and children. We used the standard methodological procedures expected by The Cochrane Collaboration. We performed meta-analysis of the selected studies using Review Manager 5 software. Fourteen RCTs (15 comparisons) including a total of 1553 participants addressing the role of CSF plus antibiotics in febrile neutropenia were included. Overall mortality was not improved by the use of CSF plus antibiotics versus antibiotics alone (hazard ratio (HR) 0.74 (95% confidence interval (CI) 0.47 to 1.16) P = 0.19; 13 RCTs; 1335 participants; low quality evidence). A similar finding was seen for infection-related mortality (HR 0.75 (95% CI 0.47 to 1.20) P = 0.23; 10 RCTs; 897

Clinicians in low resource settings in malaria endemic regions face many challenges in diagnosing and treating febrile illnesses in children. Given the change in WHO guidelines in 2010 that recommend malaria testing prior to treatment, clinicians are now required to expand the differential when malaria testing is negative. Prior studies have indicated that resource availability, need for additional training in differentiating non-malarial illnesses, and lack of understanding within the community of when to seek care play a role in effective diagnosis and treatment. The objective of this study was to examine the various factors that influence clinician behavior in diagnosing and managing children presenting with fever to health centres in Kenya. A total of 20 clinicians (2 paediatricians, 1 medical officer, 2 nurses, and 15 clinical officers) were interviewed, working at 5 different government-sponsored public clinic sites in two areas of Kenya where malaria is prevalent. Clinicians were interviewed one-on-one using a structured interview technique. Interviews were then analysed qualitatively for themes. The following five themes were identified: (1) Strong familiarity with diagnosis of malaria and testing for malaria; (2) Clinician concerns about community understanding of febrile illness, use of traditional medicine, delay in seeking care, and compliance; (3) Reliance on clinical guidelines, history, and physical examination to diagnose febrile illness and recognize danger signs; (4) Clinician discomfort with diagnosis of primary viral illness leading to increased use of empiric antibiotics; and (5) Lack of resources including diagnostic testing, necessary medications, and training modalities contributes to the difficulty clinicians face in assessing and treating febrile illness in children. These themes persisted across all sites, despite variation in levels of medical care. Within these themes, clinicians consistently expressed a need for reliable basic testing

Improved identification of children with vesicoureteral reflux at risk for recurrent febrile urinary tract infection may impact management decisions. We hypothesized that reflux occurring earlier during bladder filling increases the duration of exposure of the kidneys to bacteria, and, therefore, increases the risk of pyelonephritis. Children with vesicoureteral reflux and detailed voiding cystourethrogram data were identified. Bladder volume at onset of reflux was normalized for age. Demographics, reflux grade, laterality, presence/absence of bladder-bowel dysfunction and breakthrough febrile urinary tract infections were assessed. Median followup was 24 months (IQR 12 to 52). A total of 208 girls and 47 boys were analyzed with a mean ± SD age at diagnosis of 3.1 ± 2.6 years. On univariate analysis history of febrile urinary tract infection (HR 2.17, 95% CI 1.33-2.85, p = 0.01), dilating vesicoureteral reflux (HR 1.6, 95% CI 1.05-2.42, p = 0.03) and bladder-bowel dysfunction (HR 1.66, 95% CI 0.99-2.75, p = 0.05) were associated with an increased risk of breakthrough febrile urinary tract infection. Median bladder volume at onset of reflux in children with breakthrough febrile urinary tract infection was significantly less (33.1%) than in those without infection (49.5%, p = 0.003). Reflux onset at 35% predicted bladder capacity or less was associated with a significantly increased risk of breakthrough febrile urinary tract infection on multivariate analysis (HR 1.58, 95% CI 1.05-2.38, p = 0.03). Children with early filling vesicoureteral reflux are at increased risk for breakthrough febrile urinary tract infection independent of reflux grade. Bladder volume at onset of reflux should be recorded during cystograms since it provides additional prognostic information about the risk of pyelonephritis and resolution, and may assist with counseling and clinical decision making.

Our genetic analyses of uncharacterized bunyaviruses isolated in Peru identified a possible reassortant virus containing small and large gene segment sequences closely related to the Caraparu virus and a medium gene segment sequence potentially derived from an unidentified group C orthobunyavirus. Neutralization tests confirmed serologic distinction among the newly identified virus and the prototype and Caraparu strains. This virus, named Itaya, was isolated in 1999 and 2006 from febrile patients in the cities of Iquitos and Yurimaguas in Peru. The geographic distance between the 2 cases suggests that the Itaya virus could be widely distributed throughout the Amazon basin in northeastern Peru. Identification of a new Orthobunyavirus species that causes febrile disease in humans reinforces the need to expand viral disease surveillance in tropical regions of South America. PMID:25898901

Although one third of febrile seizures are complex, a consensus has still not been reached on how to manage them, as is the case with simple febrile seizures. The objective of this study is to estimate the usefulness of complementary examinations and the risk of associated serious intracranial pathology. A retrospective review was conducted from 2003 until 2011 on patients from 6 months to 6 years presenting with a complex febrile seizure admitted to a tertiary care hospital, excluding the cases with previous neurological disease. Epidemiological and clinic variables were collected, as well as complementary tests and complications. We found 65 patients (31 females and 34 males), of whom 44 had repeated seizures in the first 24 hours, with 15 having focal seizures. The vast majority (90%) of the recurrences occurred before 15 hours. The mean age was 20.7 months and temperature was 39.1 ± 0.12°C. None of the patients had severe intracranial pathology. The electroencephalogram gave no helpful information for the diagnosis. Neuroimaging was normal in all studied cases. The incidence of complications in complex febrile seizure in our series did not justify the systematic admission or the systematic study with complementary tests when the neurological examination was normal. The routine electroencephalogram does not appear to be justified. Copyright © 2012 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

To describe and analyze the chronological evolution of the radiological findings in seven children with febrile infection-related epilepsy syndrome. This is a retrospective study describing the radiological findings and evolution in seven children with febrile infection-related epilepsy syndrome who presented from 2009 to 2013. The children all fit the defined clinical criteria for febrile infection-related epilepsy syndrome; all had a history of normal psychomotor development who presented with acute-onset catastrophic partial status epilepticus associated with a febrile illness or unspecific infectious process. The children were identified from the author's weekly review of the pediatric inpatient service, and then the data were collected and analyzed retrospectively. Six males and one female ranging from 3 months to 9 years of age presented with status epilepticus preceded by a febrile illness. Extensive investigations for infectious, autoimmune, and metabolic etiologies were unremarkable. Multiple antiepileptic medications were attempted, including drug-induced coma in all of them, with poor response. Immunotherapy with intravenous steroids or intravenous immunoglobulin (three patients had both) was tried in six of seven patients with a poor response. Ketogenic diet was initiated in four of seven patients with limited response. Serial magnetic resonance imaging studies, done from the initial presentation through 18 months of follow-up, showed evolution from normal imaging to severe cerebral atrophy. Progressive cytotoxic edema involving mostly bilateral hippocampi and temporal lobes was appreciated in one to three weeks. At one month from seizure onset, mild to moderate cerebral atrophy and hippocampal sclerosis was appreciated that continued to progress over the next year. After six to twelve months, most of the patients showed moderate to severe cerebral atrophy and by one year, cerebellar atrophy was also appreciated. Febrile infection-related epilepsy

Full Text Available Case series summary At different time points spanning 6 months, three adopted feral flea-infested cats, residing in the household of a veterinary technician, became acutely anorexic, lethargic and febrile. Enrichment blood culture/PCR using Bartonella alpha Proteobacteria growth medium (BAPGM confirmed initial infection with the same Bartonella henselae genotype in all three cases. With the exception of anemia and neutropenia, complete blood counts, serum biochemical profiles and urinalysis results were within reference intervals. Also, tests for feline leukemia virus, feline immunodeficiency virus, Toxoplasma gondii and feline coronavirus antibodies were negative. Serial daily temperature monitoring in one case confirmed a cyclic, relapsing febrile temperature pattern during 1 month, with resolution during and after treatment with azithromycin. Bartonella henselae Western immunoblot (WB results did not consistently correlate with BAPGM enrichment blood culture/PCR results or B henselae indirect fluorescent antibody (IFA titers, and WB titration results were not informative for establishing antibiotic treatment failure. During the respective follow-up periods, no illnesses or additional febrile episodes were reported, despite repeat documentation of B henselae bacteremia in two cats available for follow-up (one with the same genotype and the other with a different B henselae genotype; one cat was, unfortunately, killed by dogs before follow-up testing. Relevance and novel information We conclude that microbiological diagnosis and treatment of B henselae infection in cats can be challenging, that antibody titration results and resolution of clinical abnormalities may not correlate with a therapeutic cure, and that fever and potentially neutropenia should be differential diagnostic considerations for young cats with suspected bartonellosis.

Martin Offringa

Full Text Available BACKGROUND Febrile seizures occurring in a child older than one month during an episode of fever affect 2% to 4% of children in Great Britain and the United States and recur in 30%. Rapid-acting antiepileptics and antipyretics given during subsequent fever episodes have been used to avoid the adverse effects of continuous antiepileptic drugs. OBJECTIVE To evaluate the effectiveness and safety of antiepileptic and antipyretic drugs used prophylactically to treat children with febrile seizures. METHODS Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL (The Cochrane Library 2011. Issue 3; MEDLINE (1966 to May 2011; EMBASE (1966 to May 2011; Database of Abstracts of Reviews of Effectiveness (DARE (May 2011. No language restrictions were imposed. We also contacted researchers in the field to identify continuing or unpublished studies. Selection criteria: Trials using randomized or quasi-randomized patient allocation that compared the use of antiepileptic or antipyretic agents with each other, placebo or no treatment. Data collection and analysis: Two review authors (RN and MO independently applied pre-defined criteria to select trials for inclusion and extracted the pre-defined relevant data, recording methods for randomization, blinding and exclusions. Outcomes assessed were seizure recurrence at 6, 12, 18, 24, 36 months and at age 5 to 6 years in the intervention and non-intervention groups, and adverse medication effects. The presence of publication bias was assessed using funnel plots. MAIN RESULTS Thirty-six articles describing 26 randomized trials with 2740 randomized participants were included. Thirteen interventions of continuous or intermittent prophylaxis and their control treatments were analyzed. Methodological quality was moderate to poor in most studies. We could not do a meta-analysis for 8 of the 13 comparisons due to insufficient numbers of trials. No significant benefit for valproate, pyridoxine

Retrospective study. The objective of this study was to investigate the clinical risk factors for febrile urinary tract infection (UTI) in spinal cord injury-associated neurogenic bladder (NB) patients who perform routine clean intermittent catheterization (CIC). Rehabilitation Hospital, Kobe, Japan. Over a 3-year period, we retrospectively assessed the clinical risk factors for febrile UTI in 259 spinal cord injury patients diagnosed as NB and performing routine CIC with regard to the factors such as gender, the presence of pyuria and bacteriuria, and the categories of the American Spinal Injury Association (ASIA) impairment scale. A total of 67 patients had febrile UTI in the follow-up period, with 57 cases of pyelonephritis, 11 cases of epididymitis and 2 cases of prostatitis, including the patients with plural infectious diseases. The causative bacteria were ranked as follows: Escherichia coli (74 cases), Pseudomonas aeruginosa (17 cases), Enterococcus faecalis (14 cases) and Klebsiella pneumoniae (12 cases). Antibiotic-resistant E. coli were seen, with 10.5% instances of extended-spectrum β-lactamase (ESBL) production and 23.8% of fluoroquinolone resistance. Multivariate analyses of clinical risk factors for febrile UTI showed that gender (male, P=0.0431), and ASIA impairment scale C or more severe (P=0.0266) were significantly associated with febrile UTI occurrence in NB patients with routine CIC. Our data demonstrated gender (male) and ASIA impairment scale C or more severe were significantly associated with febrile UTI occurrence in NB patients using routine CIC. Further prospective studies are necessary to define the full spectrum of possible risk factors for febrile UTI in these patients.

Jennifer K Light

2013-09-01

Full Text Available Introduction: Early antibiotic administration is recommended in newborns presenting with febrile illness to emergency departments (ED to avert the sequelae of serious bacterial infection. Although ED crowding has been associated with delays in antibiotic administration in a dedicated pediatric ED, the majority of children that receive emergency medical care in the U.S. present to EDs that treat both adult and pediatric emergencies. The purpose of this study was to examine the relationship between time to antibiotic administration in febrile newborns and crowding in a general ED serving both an adult and pediatric population.Methods: We conducted a retrospective chart review of 159 newborns presenting to a general ED between 2005 and 2011 and analyzed the association between time to antibiotic administration and ED occupancy rate at the time of, prior to, and following infant presentation to the ED.Results: We observed delayed and variable time to antibiotic administration and found no association between time to antibiotic administration and occupancy rate prior to, at the time of, or following infant presentation (P > 0.05. ED time to antibiotic administration was not associated with hospital length of stay, and there was no inpatient mortality.Conclusion: Delayed and highly variable time to antibiotic treatment in febrile newborns was common but unrelated to ED crowding in the general ED study site. Guidelines for time to antibiotic administration in this population may reduce variability in ED practice patterns. [West J Emerg Med. 2013;14(5:518-524.

Full Text Available The aim of this study was to determine the incidence and causes of fever as a major problem contributing to transplantation related mortality among patients undergoing hematopoietic stem cell transplantation (HSCT and evaluation of antibiotic use, according to reliable guidelines.We retrospectively reviewed hospital records of 195 adult patients who underwent HSCT between 2009-2011 at hematology-oncology and bone marrow transplantation research center. Baseline information and also data related to fever and neutropenia, patient's outcomes, duration of hospitalization and antibiotic use pattern were documented.A total of 195 patients were analyzed and a total of 268 febrile episodes in 180 patients were recorded (mean 1.5 episodes per patient. About 222 episodes (82% were associated with neutropenia which one-fourth of them were without any documented infection sources. Microbiologic documents showed that the relative frequencies of gram positive and gram negative bacteria were 62.5% and 37.5%, respectively. The hospital stay duration was directly related to the numbers of fever episodes (P<0.0001.The rate of febrile episodes in autologous stem cell transplantation was significantly higher compared to allogeneic type (P<0.05.It is necessary to determine not only the local profile of microbiologic pattern, but also antibiotic sensitivities in febrile neutropenic patients following hematopoietic stem cell transplantation, and reassess response to antibiotic treatment to establish any necessity for modifications to treatment guidelines in order to prevent any fatal complications from infection.

Aim: To describe chest radiographic abnormalities and assess their usefulness for predicting causes of fever in a resource-limited setting. Materials and methods: Febrile patients were enrolled in Moshi, Tanzania, and chest radiographs were evaluated by radiologists in Tanzania and the United States. Radiologists were blinded to the results of extensive laboratory evaluations to determine the cause of fever. Results: Of 870 febrile patients, 515 (59.2%) had a chest radiograph available; including 268 (66.5%) of the adolescents and adults, the remainder were infants and children. One hundred and nineteen (44.4%) adults and 51 (20.6%) children were human immunodeficiency virus (HIV)-infected. Among adults, radiographic abnormalities were present in 139 (51.9%), including 77 (28.7%) with homogeneous and heterogeneous lung opacities, 26 (9.7%) with lung nodules, 25 (9.3%) with pleural effusion, 23 (8.6%) with cardiomegaly, and 13 (4.9%) with lymphadenopathy. Among children, radiographic abnormalities were present in 87 (35.2%), including 76 (30.8%) with homogeneous and heterogeneous lung opacities and six (2.4%) with lymphadenopathy. Among adolescents and adults, the presence of opacities was predictive of Streptococcus pneumoniae and Coxiella burnetii, whereas the presence of pulmonary nodules was predictive of Histoplasma capsulatum and Cryptococcus neoformans. Conclusions: Chest radiograph abnormalities among febrile inpatients are common in northern Tanzania. Chest radiography is a useful adjunct for establishing an aetiologic diagnosis of febrile illness and may provide useful information for patient management, in particular for pneumococcal disease, Q fever, and fungal infections

Full Text Available Abstract Background The average annual reported dengue incidence in Cambodia is 3.3/1,000 among children Methods In 2006, active fever surveillance was conducted among a cohort of 6,694 children aged ≤ 15 years in 16 villages in Kampong Cham province, Cambodia. Subsequently, a case-control study was performed by individually assigning one non-dengue febrile control from the cohort to each laboratory-confirmed dengue case. Parents of cases and controls were interviewed using a standardized questionnaire to determine household-level, illness-related expenditures for medical and non-medical costs, and estimated income loss (see Additional file 1. The household socio-economic status was determined and its possible association with health seeking behaviour and the ability to pay for the costs of a febrile illness. Additional File 1 2006 cost study survey questionnaire, Cambodia. the questionnaire represents the data collection instrument that was developed and used during the present study. Click here for file Results Between September and November 2006, a total of 60 household heads were interviewed: 30 with dengue-positive and 30 with dengue-negative febrile children. Mean total dengue-related costs did not differ from those of other febrile illnesses (31.5 vs. 27.2 US$, p = 0.44. Hospitalization almost tripled the costs of dengue (from 14.3 to 40.1 US$ and doubled the costs of other febrile illnesses (from 17.0 to 36.2 US$. To finance the cost of a febrile illness, 67% of households incurred an average debt of 23.5 US$ and higher debt was associated with hospitalization compared to outpatient treatment (US$ 23.1 vs. US$ 4.5, p Conclusion In Cambodia, dengue and other febrile illnesses pose a financial burden to households. A possible reason for a lower rate of hospitalization among children from poor households could be the burden of higher illness-related costs and debts.

Objectives To develop the infrastructure and demonstrate the feasibility of conducting microarray-based RNA transcriptional profile analyses for the diagnosis of serious bacterial infections in febrile infants 60 days and younger in a multicenter pediatric emergency research network. Methods We designed a prospective multicenter cohort study with the aim of enrolling more than 4000 febrile infants 60 days and younger. To ensure success of conducting complex genomic studies in emergency department (ED) settings, we established an infrastructure within the Pediatric Emergency Care Applied Research Network, including 21 sites, to evaluate RNA transcriptional profiles in young febrile infants. We developed a comprehensive manual of operations and trained site investigators to obtain and process blood samples for RNA extraction and genomic analyses. We created standard operating procedures for blood sample collection, processing, storage, shipping, and analyses. We planned to prospectively identify, enroll, and collect 1 mL blood samples for genomic analyses from eligible patients to identify logistical issues with study procedures. Finally, we planned to batch blood samples and determined RNA quantity and quality at the central microarray laboratory and organized data analysis with the Pediatric Emergency Care Applied Research Network data coordinating center. Below we report on establishment of the infrastructure and the feasibility success in the first year based on the enrollment of a limited number of patients. Results We successfully established the infrastructure at 21 EDs. Over the first 5 months we enrolled 79% (74 of 94) of eligible febrile infants. We were able to obtain and ship 1 mL of blood from 74% (55 of 74) of enrolled participants, with at least 1 sample per participating ED. The 55 samples were shipped and evaluated at the microarray laboratory, and 95% (52 of 55) of blood samples were of adequate quality and contained sufficient RNA for expression

The diagnosis and management of urinary tract infections (UTIs) in young children are clinically challenging. This report was developed to inform the revised, evidence-based, clinical guideline regarding the diagnosis and management of initial UTIs in febrile infants and young children, 2 to 24 months of age, from the American Academy of Pediatrics Subcommittee on Urinary Tract Infection. The conceptual model presented in the 1999 technical report was updated after a comprehensive review of published literature. Studies with potentially new information or with evidence that reinforced the 1999 technical report were retained. Meta-analyses on the effectiveness of antimicrobial prophylaxis to prevent recurrent UTI were performed. Review of recent literature revealed new evidence in the following areas. Certain clinical findings and new urinalysis methods can help clinicians identify febrile children at very low risk of UTI. Oral antimicrobial therapy is as effective as parenteral therapy in treating UTI. Data from published, randomized controlled trials do not support antimicrobial prophylaxis to prevent febrile UTI when vesicoureteral reflux is found through voiding cystourethrography. Ultrasonography of the urinary tract after the first UTI has poor sensitivity. Early antimicrobial treatment may decrease the risk of renal damage from UTI. Recent literature agrees with most of the evidence presented in the 1999 technical report, but meta-analyses of data from recent, randomized controlled trials do not support antimicrobial prophylaxis to prevent febrile UTI. This finding argues against voiding cystourethrography after the first UTI.

1. Intravenous injections of leucocytic pyrogen in doses of 15, 30 and 60 mul./kg caused febrile reactions in male rabbits that were related to age of the animal: rabbits under 2 yr of age developed fevers that were related to dose of pyrogen, while rabbits 2-3 yr old showed large febrile responses which were not dose-related.2. Female rabbits of comparable ages generally showed smaller febrile reactions to I.V. leucocytic pyrogen, and still older females (3-5 yr) developed fever only after the largest dose.3. Dose-related febrile responses to 2.5, 5 and 10 mul. leucocytic pyrogen given intracerebroventricularly (I.C.V.) were greater in male rabbits 1-3 yr old than in females of comparable age. Female rabbits 3-5 yr old showed dose-related fevers that were smaller than those of younger animals of both sexes.4. There were no major differences in response to 125, 250 and 500 ng PGE(2), given I.C.V., between male and female rabbits under 2 yr of age. Females 2-3 yr of age had greater responses to PGE(2) than males of comparable age whilst the oldest females showed smaller responses.5. It is concluded that the febrile response of the rabbit to peripheral and central leucocytic pyrogen varies with both age and sex. Differences in sensitivity of central fever controls to endogenous pyrogen in animals of different ages and sexes may account for the different responses to peripheral pyrogen.

Fever is a common symptom of urinary tract infection (UTI) in children less than 5 years of age. Little attention is however paid to UTI as a cause of fever in this age group. The objective of the following study is to determine the prevalence of UTI in febrile children less than 5 years of age and relate it to demographic and clinical characteristics. Urine specimen of febrile children aged 1-59 months obtained by suprapubic or midstream methods were analyzed using standard laboratory methods of microscopy, culture and sensitivity. A total of 200 children were enrolled; nearly 56% (112/200) were males. The mean age of the subjects was 31.14 ± 17.96 months. The prevalence of UTI was 11% and was significantly higher in females than in males ( P = 0.049). Children below 12 months of age had a higher rate of UTI than those 12 months and above ( P = 0.028). The common clinical features were vomiting, abdominal pain, diarrhea, urinary frequency and urgency but none had a significant association with UTI. UTI is common in febrile under-fives especially among females and infants. No association was apparent between the occurrence of UTI and clinical parameters.

We prospectively investigated the impact of risk factors for febrile urinary tract infection in infants with postnatally confirmed prenatal hydronephrosis. Patients seen for prenatal hydronephrosis from 2010 to 2013 were prospectively followed. Those with ectopic ureters and ureteroceles, posterior urethral valves and neuropathic bladders were excluded. The primary outcome was febrile catheter specimen urinary tract infection. We performed univariate analysis of 7 a priori risk factors, including age, hydronephrosis grade (low-I or II vs high-III or IV), type (isolated hydronephrosis vs hydroureteronephrosis), continuous antibiotic prophylaxis, vesicoureteral reflux grade, gender and circumcision status. Time to febrile urinary tract infection curves analyzed by Cox proportional regression were generated to adjust for confounders. We collected data on 334 patients, of whom 78% were male. A febrile urinary tract infection developed in 65 patients (19%) at a median of 4 months (range 1 to 31). High grade hydronephrosis was present in 192 infants (57%). Continuous antibiotic prophylaxis was prescribed in 96 cases (29%). Of patients on continuous antibiotic prophylaxis 69% had high grade hydronephrosis. Vesicoureteral reflux was identified in 57 of 238 patients in whom voiding cystourethrogram was done. Reflux was grade I to III in 14 cases and grade IV or V in 43. Two-thirds of the patients with reflux were on continuous antibiotic prophylaxis. Circumcision was performed in 95 males (36%). Cox proportional regression identified female gender (HR 3.3, p = 0.02), uncircumcised males (HR 3.2, p = 0.02), hydroureteronephrosis (HR 10.9, p hydronephrosis was also a significant risk factor (HR 3.0, p = 0.04). After patients with vesicoureteral reflux were excluded from the study, females and uncircumcised males with high grade hydroureteronephrosis had significantly higher febrile urinary tract infection rates. Therefore, those patients may benefit from continuous

Stress-induced hyperthermia following rectal thermometry is reported in normothermic rats, but appears to be muted or even absent in febrile rats. We therefore investigated whether the use of rectal thermometry affects the accuracy of temperature responses recorded in normothermic and febrile rats. Using intra-abdominally implanted temperature-sensitive radiotelemeters we measured the temperature response to rectal temperature measurement in male Sprague Dawley rats (~200g) injected subcutaneously with Brewer's yeast (20ml/kg of a 20% Brewer's yeast solution=4000mg/kg) or saline (20ml/kg of 0.9% saline). Rats had been pre-exposed to, or were naive to rectal temperature measurement before the injection. The first rectal temperature measurement was taken in the plateau phase of the fever (18h after injection) and at hourly intervals thereafter. In normothermic rats, rectal temperature measurement was associated with an increase in abdominal temperature (0.66±0.27°C) that had a rapid onset (5-10min), peaked at 15-20min and lasted for 35-50min. The hyperthermic response to rectal temperature measurement was absent in febrile rats. Exposure to rectal temperature measurement on two previous occasions did not reduce the hyperthermia. There was a significant positive linear association between temperatures recorded using the two methods, but the agreement interval identified that rectal temperature measured with a thermocouple probe could either be 0.7°C greater or 0.5°C lower than abdominal temperature measured with radiotelemeter. Thus, due to stress-induced hyperthermia, rectal thermometry does not ensure accurate recording of body temperature in short-spaced, intermittent intervals in normothermic and febrile rats.

The aim of this study was to look at the aetiological factors presenting as acute febrile illness in cirrhotic patients. The study group included all cirrhotic patients admitted as inpatients between January and December 2011 with a history of fever of less than seven days duration. Detailed history, clinical examination and investigations, as required, were noted. The data collected were analysed. A total of 42 patients formed the study group. The male-to-female ratio was 9.5:1. The mean age at presentation was 45.09 years (24-77 years). The aetiological factors for fever were: spontaneous bacterial peritonitis (20), lower respiratory tract infection (8), urinary tract infection (6), lower limb cellulitis (4), acute cholecystitis (2) and malaria (2). The mean MELD (model for end-stage liver disease) score at presentation was 20.4. Three patients with spontaneous bacterial peritonitis (SBP) and a mean MELD score of 31 died during the hospital admission. Febrile illness in cirrhosis is attributable to multiple causes. Outcome is dependent on the severity of underlying liver disease.

To determine prevalence and risk factors for renal scar in children referred for urologic assessment of febrile UTI and/or VUR. Pre-determined risk factors for renal scar were prospectively recorded in consecutive patients referred for UTI/VUR. Age, gender, VUR grade, and reported number of febrile and non-febrile UTIs were analyzed with logistic regression to determine risk for focal cortical defects on non-acute DMSA. Of 565 consecutive children, 24 (4%) had congenital renal dysplasia and 84 (15.5%) had focal defect(s). VUR, especially grades IV-V, recurrent febrile UTI, and older age increased risk. For any age child with the same number of UTIs, VUR increased odds of renal defect 5.4-fold (OR = 5.4, 95% CI = 2.7-10.6, AUC = 0.759). Focal DMSA defects were present in 15.5% of 565 consecutive children referred for febrile UTI and/or VUR; 4% had presumed congenital reflux nephropathy without cortical defect. All VUR grades increased risk for these defects, as did recurrent febrile UTIs and older age. However, 43% with grades IV-V VUR and 76% with recurrent UTI had normal DMSA. Published by Elsevier Ltd.

Conclusion - This suggests that mutations in these three genes are not a prevalent cause of familial cases of FS and epilepsy or GEFS+ in Scandinavia....

Is the addition of aminoglycosides to beta-lactams in cancer patients with febrile neutropenia needed?

Science.gov (United States)

Contreras, Valeria; Sepúlveda, Sebastián; Heredia, Ana

2016-02-24

It is still controversial if the combined use of beta-lactam antibiotics and aminoglycosides has advantages over broad-spectrum beta-lactam monotherapy for the empirical treatment of cancer patients with febrile neutropenia. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified three systematic reviews including 14 pertinent randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded the combination of beta-lactam antibiotics and aminoglycosides probably does not lead to a reduced mortality in febrile neutropenic cancer patients and it might increase nephrotoxicity.

Tendo em vista a importância tecnológica dessa técnica e do grande interesse nacional e internacional, principalmente no ramo da indústria alimentícia, sobre os benefícios do encapsulamento, o presente estudo prospectivo teve como objetivo avaliar o panorama mundial relativo ao tema em questão, correlacionando-o com os documentos de patentes depositados. Para tanto, realizou-se uma pesquisa das patentes na base de dados europeia Espacenet®, utilizando os descritores do tema em estudo associados aos códigos de classificação. As informações encontradas foram compiladas em gráficos e discutidas. Pôde-se observar que o maior número de patentes referiu-se ao código A23L1/00 - alimentos ou produtos alimentícios: a sua preparação ou tratamento e houve um crescimento exponencial em relação ao depósito de patentes nos últimos 10 anos, sendo os Estados Unidos o país líder em número de patentes depositadas (60%. A Firmenich e CIE lidera o ranking com mais patentes depositadas. Em relação à área de atuação, predomina a indústria alimentícia (69%. No que diz respeito ao Brasil, o país aparece com apenas 1 patente detentora desta tecnologia, sendo um número bastante reduzido o que mostra a falta de incentivo neste setor. Diante dos resultados obtidos, concluiu-se que, apesar de ser uma tecnologia recente, observa-se uma tendência ao crescimento de depósito de patentes.

In this study, we aimed to determine the relation of TLR-4 Asp299Gly and Thr399Ile polymorphisms and monocyte/neutrophil TLR-4 expression to febrile urinary tract infection (UTI) and renal scar development in children. The study was performed in children with a history of febrile UTI. Patients with and without renal scarring were classified as group 1 and group 2, respectively, while the control cases in our previous study were used as the control group (group 3). All three groups were compared for the rate of TLR-4 Asp299Gly and Thr399Ile polymorphisms, and for basal and lipopolysaccharide-stimulated monocyte/neutrophil TLR-4 expression levels. There were 168 patients (86 in group 1, 82 in group 2) and 120 control cases. Monocyte/neutrophil TLR-4 expression levels were similar in groups 1 and 2. However, both groups had lower TLR-4 expression than group 3. The rate of TLR-4 Asp299Gly polymorphism was not different in all groups. TLR-4 Thr399Ile polymorphism was higher in groups 1 and 2 than in group 3 (14.0, 12.2, and 2.0 %, respectively), while group 1 and group 2 were not different. Furthermore, monocyte TLR-4 expression level was lower in those having TLR-4 Thr399Ile polymorphism than in those without this polymorphism. Patients with febrile UTI had more frequent TLR-4 Thr399Ile polymorphism and lower monocyte/neutrophil TLR-4 expression. These findings indicate that children carrying TLR-4 Thr399Ile polymorphism and/or having low level of monocyte/neutrophil TLR-4 expression have a tendency to develop febrile UTI. However, we could not show the association of TLR-4 polymorphisms and of TLR-4 expression level to renal scarring.

Full Text Available Fever is one of the more common chief complaints of patients who visit emergency departments (ED. Many febrile patients have markedly elevated C-reactive protein (CRP levels and normal white blood cell (WBC counts. Most of these patients have bacterial infection and no previous underlying disease of impaired WBC functioning. We reviewed patients who visited our ED between November 2003 and July 2004. The WBC count and CRP level of patients over 18 years of age who visited the ED because of or with fever were recorded. Patients who had normal WBC count (4,000–10,000/mL and high CRP level (> 100 mg/L were included. The data, including gender, age and length of hospital stay, were reviewed. Underlying diseases, diagnosis of the febrile disease and final condition were recorded according to the chart. Within the study period, 54,078 patients visited our ED. Of 5,628 febrile adults, 214 (3.8% had elevated CRP level and normal WBC count. The major cause of febrility was infection (82.24%. Most of these patients were admitted (92.99%. There were 32 patients with malignant neoplasm, nine with liver cirrhosis, 66 with diabetes mellitus and 11 with uremia. There were no significant differences in age and gender between patients with and those without neoplasm. However, a higher inhospital mortality rate and other causes of febrility were noted in patients with neoplasm. It was not rare in febrile patients who visited the ED to have a high CRP level but normal WBC count. These patients did not necessarily have an underlying malignant neoplasm or hematologic illness. Factors other than malignant neoplasm or hematologic illness may be associated with the WBC response, and CRP may be a better indicator of infection under such conditions.

BACKGROUND: Only few studies have addressed the long-term neurological outcomes of children born by subfertile couples. We studied the risk of epilepsy and febrile seizures in children of treated and untreated subfertile couples. METHODS: The study included 83 194 live singletons born by mothers...... who took part in the Danish National Birth Cohort (DNBC). Information on time to pregnancy (TTP) and infertility treatment was reported by the mothers in computer-assisted telephone interviews. Data on epilepsy and febrile seizures were extracted from the Danish National Hospital Register. RESULTS......: Overall, children of subfertile couples (TTP > 12 months) had a 51% higher risk of epilepsy [incidence rate ratio (IRR): 1.51; 95% confidence interval (95% CI): 1.17-1.94] compared with children of couples with a TTP of 0-5 months. The corresponding estimates were 1.71 (95% CI: 1.21-2.42) if the couples...

Pediatric febrile urinary tract infections: the current state of play

2011-11-01

Full Text Available Abstract Studies undertaken in recent years have improved our understanding regarding the consequences and management of febrile urinary tract infections (UTIs, which are amongst the most common serious bacterial infections in childhood, with renal scarring a frequent outcome. In the past pyelonephritic scarring of the kidney, often associated with vesico-ureteral reflux (reflux nephropathy was considered a frequent cause of chronic renal insufficiency in children. Increasing recognition as a consequence of improved antenatal ultrasound, that the majority of these children had congenital renal hypo-dysplasia, has resulted in a number of studies examining treatment strategies and outcomes following UTI. In recent years there is a developing consensus regarding the need for a less aggressive therapeutic approach with oral as opposed to intravenous antibiotics, and less invasive investigations, cystourethrography in particular, following an uncomplicated first febrile UTI. There does remain a concern that with this newer approach we may be missing a small subgroup of children more prone to develop severe kidney damage as a consequence of pyelonephritis, and in whom some form of intervention may prove beneficial. These concerns have meant that development of a universally accepted diagnostic protocol remains elusive.

We retrospectively assessed the incidence of and risk factors for febrile urinary tract infection in children during active surveillance after early discontinuation of antibiotic prophylaxis. We retrospectively evaluated 9 females and 61 uncircumcised males diagnosed with primary vesicoureteral reflux before age 1 year who had persistent reflux on followup voiding cystourethrogram and were subsequently followed under active surveillance without continuous antibiotic prophylaxis. Patients with secondary vesicoureteral reflux or associated urological abnormality were excluded. Clinical outcomes, including incidence of febrile urinary tract infection and new scar formation, were evaluated. Risk factors for febrile urinary tract infection were also analyzed. Mean age at stopping continuous antibiotic prophylaxis was 21 months, and mean followup was 61 months. During active surveillance 21 patients had febrile urinary tract infection, and the 5-year infection-free rate under active surveillance was 67.5%. One or 2 foci of minimal new scarring developed in 4 of 16 patients who underwent followup dimercapto-succinic acid scan after febrile urinary tract infection. On multivariate analysis dilated vesicoureteral reflux on followup voiding cystourethrogram was the only significant risk factor for febrile urinary tract infection. This study revealed that about two-thirds of patients with persistent vesicoureteral reflux were free of febrile urinary tract infection during 5 years of active surveillance. Those with dilated vesicoureteral reflux on followup voiding cystourethrogram are at significantly greater risk for febrile urinary tract infection. Accordingly active surveillance, especially in patients with nondilated vesicoureteral reflux on followup voiding cystourethrogram, seems to be a safe option even in children who have not yet been toilet trained.

Full Text Available In non-febrile mouse models, high dose acetaminophen administration causes profound hypothermia. However, this potentially hazardous side-effect has not been confirmed in non-febrile humans. Thus, we sought to ascertain whether an acute therapeutic dose (20 mg·kg lean body mass of acetaminophen would reduce non-febrile human core temperature in a sub-neutral environment. Ten apparently healthy (normal core temperature, no musculoskeletal injury, no evidence of acute illness Caucasian males participated in a preliminary study (Study one to determine plasma acetaminophen concentration following oral ingestion of 20 mg·kg lean body mass acetaminophen. Plasma samples (every 20 minutes up to 2-hours post ingestion were analysed via enzyme linked immunosorbent assay. Thirteen (eight recruited from Study one apparently healthy Caucasian males participated in Study two, and were passively exposed to 20°C, 40% r.h. for 120 minutes on two occasions in a randomised, repeated measures, crossover design. In a double blind manner, participants ingested acetaminophen (20 mg·kg lean body mass or a placebo (dextrose immediately prior to entering the environmental chamber. Rectal temperature, skin temperature, heart rate, and thermal sensation were monitored continuously and recorded every ten minutes. In Study one, the peak concentration of acetaminophen (14 ± 4 µg/ml in plasma arose between 80 and 100 minutes following oral ingestion. In Study two, acetaminophen ingestion reduced the core temperature of all participants, whereas there was no significant change in core temperature over time in the placebo trial. Mean core temperature was significantly lower in the acetaminophen trial compared with that of a placebo (p 0.05. The results indicate oral acetaminophen reduces core temperature of humans exposed to an environment beneath the thermal neutral zone. These results suggest that acetaminophen may inhibit the thermogenic mechanisms required to regulate

Vaccination with whole-cell pertussis vaccine carries an increased risk of febrile seizures, but whether this risk applies to the acellular pertussis vaccine is not known. In Denmark, acellular pertussis vaccine has been included in the combined diphtheria-tetanus toxoids-acellular pertussis-inactivated poliovirus-Haemophilus influenzae type b (DTaP-IPV-Hib) vaccine since September 2002. To estimate the risk of febrile seizures and epilepsy after DTaP-IPV-Hib vaccination given at 3, 5, and 12 months. A population-based cohort study of 378,834 children who were born in Denmark between January 1, 2003, and December 31, 2008, and followed up through December 31, 2009; and a self-controlled case series (SCCS) study based on children with febrile seizures during follow-up of the cohort. Hazard ratio (HR) of febrile seizures within 0 to 7 days (0, 1-3, and 4-7 days) after each vaccination and HR of epilepsy after first vaccination in the cohort study. Relative incidence of febrile seizures within 0 to 7 days (0, 1-3, and 4-7 days) after each vaccination in the SCCS study. A total of 7811 children were diagnosed with febrile seizures before 18 months, of whom 17 were diagnosed within 0 to 7 days after the first (incidence rate, 0.8 per 100,000 person-days), 32 children after the second (1.3 per 100,000 person-days), and 201 children after the third (8.5 per 100,000 person-days) vaccinations. Overall, children did not have higher risks of febrile seizures during the 0 to 7 days after the 3 vaccinations vs a reference cohort of children who were not within 0 to 7 days of vaccination. However, a higher risk of febrile seizures was found on the day of the first (HR, 6.02; 95% CI, 2.86-12.65) and on the day of the second (HR, 3.94; 95% CI, 2.18-7.10), but not on the day of the third vaccination (HR, 1.07; 95% CI, 0.73-1.57) vs the reference cohort. On the day of vaccination, 9 children were diagnosed with febrile seizures after the first (5.5 per 100,000 person-days), 12

Clinical evidence suggests that febrile status epilepticus (SE) in children can lead to acute hippocampal injury and subsequent temporal lobe epilepsy. The contribution of febrile SE to the mechanisms underlying temporal lobe epilepsy are however poorly understood. A rat model of temporal lobe epilepsy following hyperthermic SE was previously established in our laboratory, wherein a focal cortical lesion induced at postnatal day 1 (P1), followed by a hyperthermic SE (more than 30 min) at P10, leads to hippocampal atrophy at P22 (dual pathology model) and spontaneous recurrent seizures (SRS) with mild visuospatial memory deficits in adult rats. The goal of this study was to identify the long term electrophysiological, anatomical and molecular changes in this model. Following hyperthermic SE, all cortically lesioned pups developed progressive SRS as adults, characterized by the onset of highly rhythmic activity in the hippocampus. A reduction of hippocampal volume on the side of the lesion preceded the SRS and was associated with a loss of hippocampal neurons, a marked decrease in pyramidal cell spine density, an increase in the hippocampal levels of NMDA receptor NR2A subunit, but no significant change in GABA receptors. These findings suggest that febrile SE in the abnormal brain leads to hippocampal injury that is followed by progressive network reorganization and molecular changes that contribute to the epileptogenesis as well as the observed memory deficits.

Malnutrition has been reported in the literature to be adversely associated with outcomes in paediatric malignancies. Our objective in this paper was to evaluate malnutrition as a potential predictor for adverse outcomes in febrile neutropenia associated with haematological malignancies. A prospective observational study was performed in a tertiary care teaching hospital of Kolkata, India. Forty-eight participants, suffering from haematological malignancy, were included. Participants were included if they experienced at least one episode of febrile neutropenia. For children aged malnutrition, while body mass index for age was used in children ≥5 years. A total of 162 episodes of febrile neutropenia were studied. Thirty patients (30/48, 62.5%) included in the study had malnutrition. In bivariate analyses at patient level, there is a strong association between malnutrition and death (odds ratio (OR) 7.286, 95% confidence interval (CI) 0.838-63.345, one-tailed P = 0.044), and life-threatening complications show a moderate trend towards significance (OR 3.333, 95% CI 0.791-14.052, one-tailed P = 0.084). Survival functions were significantly different between malnourished and non-malnourished children (log rank test χ(2)  = 4.609, degree of freedom = 1, P = 0.032). Wasting was associated with life-threatening complications in children aged malnutrition was not. Malnutrition may be a potential predictor of mortality in febrile neutropenia. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Juliana Nunes Ferreira

Full Text Available ABSTRACT Objective: To analyze the interventions performed by health professionals with a view to managing chemotherapy-induced febrile neutropenia. Method: Integrative literature review, the sample of 12 primary articles was selected from the following databases: LILACS, SciELO, BVS, PubMed, CINAHL and Web of Science. Results: There was a prevalence of studies, realized by doctors, focused on pharmacological treatment and on the association of methods for greater diagnostic accuracy of febrile neutropenia. A study was found on pharmaceutical management regarding antibiotic dosing efficacy and a study indicating that nurses could contribute to the identification of elderly patients who would benefit from prophylactic use of growth factor. Conclusion: There was a shortage of studies involving the participation of other health professionals, besides the doctors, and a knowledge gap regarding interprofessional practice in the management of interventions specific to their area of specialism, joint interventions and non-pharmacological interventions.

To develop the infrastructure and demonstrate the feasibility of conducting microarray-based RNA transcriptional profile analyses for the diagnosis of serious bacterial infections in febrile infants 60 days and younger in a multicenter pediatric emergency research network. We designed a prospective multicenter cohort study with the aim of enrolling more than 4000 febrile infants 60 days and younger. To ensure success of conducting complex genomic studies in emergency department (ED) settings, we established an infrastructure within the Pediatric Emergency Care Applied Research Network, including 21 sites, to evaluate RNA transcriptional profiles in young febrile infants. We developed a comprehensive manual of operations and trained site investigators to obtain and process blood samples for RNA extraction and genomic analyses. We created standard operating procedures for blood sample collection, processing, storage, shipping, and analyses. We planned to prospectively identify, enroll, and collect 1 mL blood samples for genomic analyses from eligible patients to identify logistical issues with study procedures. Finally, we planned to batch blood samples and determined RNA quantity and quality at the central microarray laboratory and organized data analysis with the Pediatric Emergency Care Applied Research Network data coordinating center. Below we report on establishment of the infrastructure and the feasibility success in the first year based on the enrollment of a limited number of patients. We successfully established the infrastructure at 21 EDs. Over the first 5 months we enrolled 79% (74 of 94) of eligible febrile infants. We were able to obtain and ship 1 mL of blood from 74% (55 of 74) of enrolled participants, with at least 1 sample per participating ED. The 55 samples were shipped and evaluated at the microarray laboratory, and 95% (52 of 55) of blood samples were of adequate quality and contained sufficient RNA for expression analysis.

Full Text Available Objetivo: Describir las manifestaciones clínicas y hallazgos de laboratorio de una serie de casos febriles agudos con diagnóstico presuntivo de infección por el virus dengue. en Quindío (Colombia. Materiales y métodos: Se realizó un estudio de corte transversal, en pacientes con sospecha clínica de dengue en el periodo comprendido entre enero y agosto de 2013, en algunos centros hospitalarios del departamento del Quindío. Se tomaron muestras de sangre para diagnóstico de dengue, leptospira, malaria, hepatitis B, y rickettsiosis. Como pruebas confirmatorias para dengue se realizó aislamiento viral en células C6/36HT y serotipificación para dengue por RTPCR; pruebas de función hepática, cuadro hemático y niveles de citocinas. Resultados: Se caracterizaron 149 casos, de los cuales el 43% presentaron infección por dengue, 4% leptospira, 6,8% rickettsias, un caso de malaria y uno de hepatitis B. En 5 casos se logró el aislamiento del DENV2 y DENV3. Mediante la RT-PCR, se evidenció cocirculación de serotipos 2, 3, 4. Se encontró que las enzimas AST/ALT, el conteo de plaquetas, la erupción y el dolor abdominal fueron marcadores característicos de la infección por dengue, mientras la ictericia y el dolor lumbar se correlacionaron con la leptospirosis. Los valores de citocinas mostraron que la IL-10, TNF α variaron significativamente en casos con dengue frente a otros diagnósticos, y la IL-17 a presentó diferencias significativas en individuos con dengue grave. Conclusiones: El dengue se confirmó como causa etiológica importante de síndrome febril icterohemorrágico en el departamento del Quindío, pero la leptospirosis y la rickettsiosis tienen también una participación importante. Sin embargo, en el 44% de los casos fueron catalogados como síndrome febril indeterminado.

To confirm the linkage of familial febrile convulsions to the short arm of chromosome 6(6p) or the long arm of chromosome 8(8q). The authors finished genotyping of Pst I locus on the coding region of heat shock protein (HSP) 70, 5'untranslated region of HSP70-1, 3' untranslated region of HSP70-2, D8S84 and D8S85. The data were processed by the genotype-based haplotype relative risk(GHRR) and transmission disequilibrium test(TDT) methods in PPAP. Some signs of association and disequilibrium between D8S85 and FC were shown by GHRR and TDT. A suspect linkage of familial febrile convulsions to the long arm of chromosome 8 has been proposed.

In February 2008, we alerted the Advisory Committee on Immunization Practices to preliminary evidence of a twofold increased risk of febrile seizures after the combination measles-mumps-rubella-varicella (MMRV) vaccine when compared with separate measles-mumps-rubella (MMR) and varicella vaccines. Now with data on twice as many vaccine recipients, our goal was to reexamine seizure risk after MMRV vaccine. Using 2000-2008 Vaccine Safety Datalink data, we assessed seizures and fever visits among children aged 12 to 23 months after MMRV and separate MMR + varicella vaccines. We compared seizure risk after MMRV vaccine to that after MMR + varicella vaccines by using Poisson regression as well as with supplementary regressions that incorporated chart-review results and self-controlled analyses. MMRV vaccine recipients (83,107) were compared with recipients of MMR + varicella vaccines (376,354). Seizure and fever significantly clustered 7 to 10 days after vaccination with all measles-containing vaccines but not after varicella vaccination alone. Seizure risk during days 7 to 10 was higher after MMRV than after MMR + varicella vaccination (relative risk: 1.98 [95% confidence interval: 1.43-2.73]). Supplementary analyses yielded similar results. The excess risk for febrile seizures 7 to 10 days after MMRV compared with separate MMR + varicella vaccination was 4.3 per 10,000 doses (95% confidence interval: 2.6-5.6). Among 12- to 23-month-olds who received their first dose of measles-containing vaccine, fever and seizure were elevated 7 to 10 days after vaccination. Vaccination with MMRV results in 1 additional febrile seizure for every 2300 doses given instead of separate MMR + varicella vaccines. Providers who recommend MMRV should communicate to parents that it increases the risk of fever and seizure over that already associated with measles-containing vaccines.

Various lines of evidence have implicated cyclooxygenase (COX)-2 as a modulator of the fever induced by the exogenous pyrogen lipopolysaccharide (LPS). Thus, treatment with specific inhibitors of COX-2 suppresses the febrile response without affecting basal body (core) temperature (T(c)). Furthermore, COX-2 gene-ablated mice are unable to develop a febrile response to intraperitoneal (i.p.) LPS, whereas their COX-1-deficient counterparts produce fevers not different from their wild-type (WT) controls. To extend the apparently critical role of COX-2 for LPS-induced fevers to fevers produced by endogenous pyrogens, we studied the thermal responses of COX-1- and COX-2 congenitally deficient mice to i.p. and intracerebroventricular (i.c.v.) injections of recombinant murine (rm) interleukin (IL)-1beta. We also assessed the effects of one selective COX-1 inhibitor, SC-560, and two selective COX-2 inhibitors, nimesulide (NIM) and dimethylfuranone (DFU), on the febrile responses of WT and COX-1(-/-) mice to LPS and rmIL-1beta, i.p. Finally, we verified the integrity of the animals' responses to PGE2, i.c.v. I.p. and i.c.v. rmIL-1beta induced similar fevers in WT and COX-1 knockout mice, but provoked no rise in the T(c)s of COX-2 null mutants. The fever produced in WT mice by i.p. LPS was not affected by SC-560, but it was attenuated and abolished by NIM and DFU, respectively, while that caused by i.p. rmIL-1beta was converted into a T(c) fall by DFU. There were no differences in the responses to i.c.v. PGE2 among the WT and COX knockout mice. These results, therefore, further support the notion that the production of PGE2 in response to pyrogens is critically dependent on COX-2 expression.

Full Text Available Abstract Background Alternating ibuprofen and acetaminophen for the treatment of febrile children is a prevalent practice among physicians and parents, despite the lack of evidence on effectiveness or safety. This randomized, double-blind and placebo-controlled clinical trial aims at comparing the antipyretic effectiveness and safety of a single administration of alternating ibuprofen and acetaminophen doses to that of ibuprofen mono-therapy in febrile children. Methods Seventy febrile children were randomly allocated to receive either a single oral dose of 10 mg/kg ibuprofen and 15 mg/kg oral acetaminophen after 4 hours, or a similar dose of ibuprofen and placebo at 4 hours. Rectal temperature was measured at baseline, 4, 5, 6, 7 and 8 hours later. Endpoints included proportions of afebrile children at 6, 7 and 8 hours, maximum decline in temperature, time to recurrence of fever, and change in temperature from baseline at each time point. Intent-to-treat analysis was planned with statistical significance set at P Results A higher proportion of subjects in the intervention group (83.3% became afebrile at 6 hours than in the control group (57.6%; P = 0.018. This difference was accentuated at 7 and 8 hours (P Conclusion A single dose of alternating ibuprofen and acetaminophen appears to be a superior antipyretic regimen than ibuprofen mono-therapy. Further studies are needed to confirm these findings.

Given that YKL-40 is a known marker of inflammation, we sought to determine its association with urinary tract infection (UTI) in febrile children. In total, 44 children aged 0 to 24 months with febrile UTI and 35 age- and sex-matched controls with fever from other causes were enrolled in the study. ELISA was performed to determine the level of YKL-40 in urine collected from each child. The ratio of urinary YKL-40 to creatinine (Cr) was higher in the children with a UTI than in the controls (PUTI was 0.88 for the urinary YKL-40/Cr ratio, 0.86 for pyuria, and 0.71 for positive nitrite on urinalysis. We applied a cut-off value of 125.23 pg/mg to urinary YKL-40/Cr for detecting UTI. Eight of nine children in the control group with pyuria had urinary YKL-40/Cr levels lower than 125.23 pg/mg, and the one child in the UTI group without pyuria or positive nitrite had a urinary YKL-40/Cr level greater than 125.23 pg/mg. Determining the levels of urinary YKL-40/Cr may help identify true cases of UTI in febrile young children, especially when they have pyuria but not nitrite, or have neither pyuria nor nitrite in the urine. © The Korean Society for Laboratory Medicine

This study aims to investigate clinical characteristics and microbiological results and to assess the predictors for enterovirus infection in febrile neonates. A prospective cohort study was conducted on 334 febrile patients (age: 0.33-28 days) in 2011-2012 years. Enterovirus RNA was detected by reverse transcription polymerase chain reaction on faeces or cerebrospinal fluid (CSF). Clinical characteristics were compared, and non-conditional logistic regression analysis was performed to determine independent predictors for enterovirus infection. There were 131 episodes of neonatal enterovirus infection (39.22%). Forty-eight (36.64%) developed respiratory symptoms, 69 (52.67%) had diarrhoea, 22 (16.79%) had poor feeding and 34 (25.95%) had rash. Eighteen (13.74%) had lower platelet counts, and CSF specimens were positive for enterovirus RNA in 44.27% (58/131) whose CSF revealed a mean white blood cell counts of 100.38 ± 147.97 cells/mm(3) (range: 2-668 cells/mm(3) ). The positivity of stool 38.92% (130/334) was significantly higher than that of CSF specimens 26.24% (58/221) for enterovirus RNA (P enterovirus infection: abnormal CSF test (odds ratio (OR): 12.426, 95% confidence interval (CI): 5.633-27.413), thrombocytopenia (OR: 3.647, 95% CI: 1.312-10.136), duration of fever >3.25 (d) (OR: 2.293, 95% CI: 1.279-4.113), highest temperature >38.35 (°C) (OR: 2.094, 95% CI: 1.342-4.123) and negative bacterial culture (OR: 5.073, 95% CI: 1.504-17.114). Our data indicated that enteroviruses should be routinely considered in the differential diagnosis of febrile neonates. The factors, which may predict the risk of neonatal enterovirus infection, were abnormal CSF test, thrombocytopenia, duration of fever >3.25 (d), highest temperature >38.35 (°C) and negative bacterial culture. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

India, home to almost 1.5 billion people, is in need of a country-specific, evidence-based, consensus approach for the emergency department (ED) evaluation and management of the febrile child. We held two consensus meetings, performed an exhaustive literature review, and held ongoing web-based discussions to arrive at a formal consensus on the proposed evaluation and management algorithm. The first meeting was held in Delhi in October 2015, under the auspices of Pediatric Emergency Medicine (PEM) Section of Academic College of Emergency Experts in India (ACEE-INDIA); and the second meeting was conducted at Pune during Emergency Medical Pediatrics and Recent Trends (EMPART 2016) in March 2016. The second meeting was followed with futher e-mail-based discussions to arrive at a formal consensus on the proposed algorithm. To develop an algorithmic approach for the evaluation and management of the febrile child that can be easily applied in the context of emergency care and modified based on local epidemiology and practice standards. We created an algorithm that can assist the clinician in the evaluation and management of the febrile child presenting to the ED, contextualized to health care in India. This guideline includes the following key components: triage and the timely assessment; evaluation; and patient disposition from the ED. We urge the development and creation of a robust data repository of minimal standard data elements. This would provide a systematic measurement of the care processes and patient outcomes, and a better understanding of various etiologies of febrile illnesses in India; both of which can be used to further modify the proposed approach and algorithm.

The urinary tract infection is one of the most frequent bacterial infections in the childhood. Two hundred eleven children diagnosed as first febrile urinary tract infection patients were studied and performed Tc-DMSA renal scintigraphy in the acute phase of infection. The results were correlated to the duration and intensity of the fever before the diagnosis, to the acute phase reactants (hemogram, erythrosedimentation and reactive-C protein) and to the results of imaging studies (renal ultrasound and mictional uretrocystography)

The ethnographic study was conducted in two communities in Oyo State in Southwestern Nigeria. The study sites consisted of a rural and an urban local government area located in the tropical rain forest zone of Nigeria. The study was designed to obtain information on febrile illnesses and herbal remedies for treatment with the aim of identifying potential antimalarial drugs. The study revealed that fever is a general term for describing illnesses associated with elevated body temperature. The indigenous Yoruba ethnic population has categorized fever based on symptoms and causes. The present communication is the result of focus group discussion and semi-structured questionnaire administered to traditional healers, herb sellers, elders and mothers. This was on types of fevers, symptoms and causes of febrile illnesses. The investigation also included use of traditional herbs in the prevention and treatment of the illnesses in the two communities.A total of 514 respondents were interviewed. This was made up of 266 (51.8%) from Atiba local government area (LGA), an urban centre while 248 (48.2%) respondents were interviewed from Itesiwaju LGA, a rural community. The LGAs are located in Oyo State of Nigeria. The respondents proffered 12 types of febrile illnesses in a multiple response answering system in Yoruba language. The most common ones (direct translation into English) were: yellow fever (39.1%), typhoid (34.8%), ordinary (28.8%), rainy season (20.8%) and headache (10.5%) fevers, respectively. Perceived causes of each of the febrile illnesses included stress, mosquito bites, unclean water, rains and over exposure to the sun. Methods of fever prevention were mainly with the use of herbal decoctions, powdered herbs, orthodox medications and maintenance of proper hygiene. Of a total of 112 different herbal remedies used in the treatment of the febrile illnesses compiled from the study, 25 recipes are presented. Recipes consisted of 2-7 ingredients.

Full Text Available Members of the Chlamydiales order are obligate intracellular pathogens causing acute and chronic infectious diseases. Chlamydiaceae are established agents of community- and zoonotically acquired respiratory tract infections, and emerging pathogens among the Chlamydia-related bacteria have been implicated in airway infections. The role of both in airway infections in Africa is underexplored. We performed a case -control study on the prevalence of Chlamydiaceae and Chlamydia-related emerging pathogens in children with febrile respiratory tract infections in West Africa, Ghana. Using a pan-Chlamydiales broad-range real-time PCR, we detected chlamydial DNA in 11 (1.9% of 572 hospitalized febrile children with respiratory tract symptoms and in 24 (4.3% of 560 asymptomatic age-matched controls (p 0.03. Chlamydiaceae were found to be common among both symptomatic and healthy Ghanaian children, with Chlamydia pneumoniae being the most prevalent species. Parachlamydiaceae were detected in two children without symptoms but not in the symptomatic group. We identified neither Chlamydia psittaci nor Simkania negevensis but a member of a new chlamydial family that shared 90.2% sequence identity with the 16S rRNA gene of the zoonotic pathogen Chlamydia pecorum. In addition, we found a new Chlamydia-related species that belonged to a novel family sharing 91.3% 16S rRNA sequence identity with Candidatus Syngnamydia venezia. The prevalence and spectrum of chlamydial species differed from previous results obtained from children of other geographic regions and our study indicates that both, Chlamydiaceae and Chlamydia-related bacteria, are not clearly linked to clinical symptoms in Ghanaian children.

Full Text Available Abstract Crohn's disease is a chronic illness that may often follow a relapsing-remitting course. Many of the factors that may be associated with the spontaneous remission of this disease (i.e. not related to specific treatment remain to be determined. In the present report, we review the medical history of a patient with a long history of moderate to severe Crohn's whose complete remission immediately followed the development of a febrile infection. The patient first developed symptoms of Crohn's in her late adolescent years. At the time of diagnosis at age 23, she was placed on mesalamine - without effective control her disease symptoms. Due to progressive deterioration, the patient underwent a bowel resection at age 25. Soon afterwards symptoms recurred, gradually increasing in severity. In February 2005, at age 36, the patient developed a painful abscess associated with a rectal fistula. Other symptoms at the time included chronic bone and stomach pain, swollen joints, and debilitating fatigue. Surgical correction was scheduled in mid-March. In late February, the patient developed a respiratory infection associated with fevers of 103-104°F. After the onset of fever, the abscess pain disappeared and this was soon followed by a disappearance of all other disease symptoms. By the time the corrective surgery occurred, she had no Crohn's symptoms. Her remission lasted 10 weeks when the previous symptoms then reappeared. The patient has subsequently used a variety of conventional therapies, but still suffers from severe symptoms of her disease. In recent years, a growing body of literature has emphasized the important role that innate immunity plays in the etiology of Crohn's disease; however, a key component of innate immunity, the febrile response, has been overlooked. Other cases of spontaneous remission following febrile infection in inflammatory bowel disease have been reported. Moreover, induction of a febrile response was in the past used

Full Text Available Abstract Background Febrile neutropenia carries a high risk of sepsis complications, and the identification of biomarkers capable to identify high risk patients is a great challenge. Angiopoietins (Ang - are cytokines involved in the control microvascular permeability. It is accepted that Ang-1 expression maintains endothelial barrier integrity, and that Ang-2 acts as an antagonizing cytokine with barrier-disrupting functions in inflammatory situations. Ang-2 levels have been recently correlated with sepsis mortality in intensive care units. Methods We prospectively evaluated concentrations of Ang-1 and Ang-2 at different time-points during febrile neutropenia, and explored the diagnostic accuracy of these mediators as potential predictors of poor outcome in this clinical setting before the development of sepsis complications. Results Patients that evolved with septic shock (n = 10 presented higher levels of Ang-2 measured 48 hours after fever onset, and of the Ang-2/Ang-1 ratio at the time of fever onset compared to patients with non-complicated sepsis (n = 31. These levels correlated with sepsis severity scores. Conclusions Our data suggest that imbalances in the concentrations of Ang-1 and Ang-2 are independent and early markers of the risk of developing septic shock and of sepsis mortality in febrile neutropenia, and larger studies are warranted to validate their clinical usefulness. Therapeutic strategies that manipulate this Ang-2/Ang-1 imbalance can potentially offer new and promising treatments for sepsis in febrile neutropenia.

There are differences in the immune response, and particularly fever, between males and females. In the present study, we investigated how the febrile responses induced by lipopolysaccharide (LPS) and different endogenous pyrogens were affected by female gonadal hormones. The febrile response to i.p. injection of LPS (50 μg/kg) was 40% lower in female rats compared to male or ovariectomised (OVX) female rats. Accordingly, oestrogen replacement in OVX animals reduced LPS-induced fever. Treatment with the prostaglandin synthesis inhibitor indomethacin (2 mg/kg, i.p. 30 min before) reduced the febrile response induced by LPS in both OVX (88%) and sham-operated (71%) rats. In line with the enhanced fever in OVX rats, there was increased expression of cyclooxygenase-2 (COX-2) in the hypothalamus and elevated levels of prostaglandin E 2 (PGE 2 ). In addition, OVX rats were hyper-responsive to PGE 2 injected i.c.v. By contrast to the enhanced fever in response to LPS and PGE 2 , the febrile response induced by i.c.v. injection of interleukin (IL)-1β was unaffected by ovariectomy, whereas the responses induced by tumour necrosis factor (TNF)-α and macrophage inflammatory protein (MIP)-1α were completely abrogated. These results suggest that the mediators involved in the febrile response in females are similar to males, although the reduction of female hormones may decrease the responsiveness of some mediators such as TNF-α and MIP-1α. Compensatory mechanisms may be activated in females after ovariectomy such as an augmented synthesis of COX-2 and PGE 2 . © 2016 British Society for Neuroendocrinology.

Out of 52 patients, 5 did not develop any fever; in the remaining 47 patients there were 57 episodes of febrile neutropenia. The mean days of febrile episodes were 4.71 (range 3-8). Fever of unknown origin (FUO) occurred in 31 (54.3%) episodes. Microbiologically documented infection (MDI) occurred in 17 (29.8%) episodes of fever. Clinically documented infection (CDI) occurred in 9 (15.7%) episodes. Gram-negative organisms were isolated in 10 while gram-positive organisms in 7. Klebseilla, S. aureus were the most common isolates. Empirical therapy was effective in 12 of the 33 (36%) episodes. Out of 28, 26 (92%) responded to Imipenem/Amikacin as second line therapy while those who received any other second line combination, only 11 out of 22 (50%) showed response. Systemic Amphotericin was used in 4 patients, 2 responded. Infection related mortality rate was 4%. (author)

Recently, new predictors of vesicoureteral reflux (VUR) in children with a first febrile UTI such as Procalcitonin (PCT) were introduced as selective approaches for cystography. This study wants to show the capability of PCT in predicting presence of VUR at the first febrile UTI in children. Patients between 1 month and 15 years of age with febrile UTI were included in this prospective study. PCT values were measured through a semi-quantitative method in four grades comprising values less than 0.5, 0.5-2.0, 2.0-10.0 and above 10.0 ng/ml. The independence of PCT levels in predicting VUR were assessed after adjustment for all potential confounders using a logistic-regression model. A total of 68 patients, 54 (79.4%) girls and 14 (20.6%) boys were evaluated. PCT level demonstrated a significant difference between patients with positive VUR and those with negative VUR (P=0.012). To calculate the independent factors that may predict the presence of VUR, all included variables were adjusted for age and sex. Results of logistic regression showed that a PCT level between 2.0 and 10.0 ng/mL could independently predict presence of VUR (Odds ratio=6.11, CI 95%= 1.22-30.77, P=0.03). Our finding in this study showed that readily available semi-quantitative measures for PCT are feasible for detecting patients with VUR. We suggest that in semi-quantitative measurements of PCT, levels between 2.0 and 10.0 ng/ml could be an independent predictor of positive VUR.

Stitt, J T

The range of body temperature increases elicited by a standard dose of endogenous pyrogen (0.5 ml/kg iv) was examined in a population of 26 male New Zealand White rabbits. Although the mean maximum increase in rectal temperature was 0.88 +/- 0.06 degree C (SE), individual responses varied from 0.4 degree to 1.5 degree C. Three representative animals that responded to the standard dose of pyrogen with small, intermediate, and large febrile responses were selected and challenged with the same dose of pyrogen on eight separate occasions, and the variability of these responses was examined. There was little variability within the characteristic responses of any particular animal to the repeated challenges. The variability of the febrile responses elicited by both intravenous and intracerebroventricular administration of the same pyrogen was examined and compared using another group of 11 rabbits. The variability in response to the intravenous route was similar to that found in the larger population, whereas the variation in response to the intracerebroventricular route was smaller, and all 11 animals had fevers that were greater than 1 degrees C. It is concluded that the variability of the febrile responses of rabbits to intravenous pyrogen was due to differences between individual sensitivities of animals to the intravenously administered pyrogen. This difference in sensitivity may be due to a difference in the amount of pyrogen that reaches the putative receptor sites, or to a difference in the density or effectiveness of receptor sites in translating the pyrogenic stimulus into a fever response.

Full Text Available Abstract Background Malaria remains one of the most important tropical diseases of human with 1–2 million deaths annually especially caused by P. falciparum. During malarial life cycle, they exposed to many environmentally stresses including wide temperature fluctuation and pharmacological active molecules. These trigger malarial evolutionarily adaptive responses. The effect of febrile temperature on malarial growth, development and drug susceptibility by mimicking patient in treatment failure before and after drug uptake was examined. Methods Sensitivities of P. falciparum to antimalarial drug (chloroquine, mefloquine, quinine and artesunate were investigated based on the incorporation of [3H] hypoxanthine into parasite nucleic acids or radioisotopic technique. The number of parasites was examined under microscope following Giemsa staining and the parasite development at the end of each phase was counted and comparison of parasite number was made. The proteome was separated, blotted and hybridized with anti-Hsp70s primary antibody. The hybridized proteins were separately digested with trypsin and identified by MALDI-TOF peptide mass fingerprint. Results The results show that febrile temperature is capable of markedly inhibiting the growth of field isolate P. falciparum but not to K1 and 3D7 standard strains. K1 and 3D7 grown under heat shock developed greater and the reinfection rate was increased up to 2-folds when compared to that of non-heat shock group. The IC50 value of K1 toward chloroquine, mefloquine and quinine under heat shock was higher than that of K1 under non-heat shock which is opposite to that of 3D7. Heat shock caused death in field isolated parasite. It was also found that the febrile temperature coped with chloroquine uptake had no effect to the development, drug sensitivity and the parasite number of K1 strain. In the opposite way, heat shock and chloroquine shows extremely effect toward 3D7 and field isolate PF91 as shown

The empirical administration of a broad-spectrum beta-lactam antibiotic, either as monotherapy or in combination with an aminoglycoside, is an essential component of the initial management of patients with fever and severe neutropenia. Multiple antibiotics have been tested for this indication. Cefepime is a fourth-generation cephalosporin with in vitro activity against most gram-negative and many gram-positive bacteria. We have studied the use of this agent as monotherapy in this indication. One hundred and twenty-six episodes of febrile neutropenia in 98 adults with hematological malignancies were treated with cefepime monotherapy. Cefepime was given at a dose of 2 g every 8 h i.v. Most episodes (49%) were fever of unexplained origin, while a microbiologically documented and clinically documented infection occurred in 25% episodes each. Seventy-six (61%) episodes occurred after conventional chemotherapy, while 51 (41%) after a hematopoietic stem cell transplantation. Twelve episodes (10%) were not evaluable for response. Among the 114 evaluable episodes, 69 (55% of the initial sample and 61% of those evaluable) responded to cefepime monotherapy, while therapy failed in 45 cases (36% of the initial sample and 39% of those evaluable), including 14 cases who developed breakthrough bacteremia during therapy. There were no deaths due to bacterial infection. At the end of all antibiotic therapy (final outcome) 69 episodes were cured only with monotherapy, 47 were cured with modification of therapy and 10 patients died from an unrelated cause. The only variable that appeared to correlate with response to therapy was the duration of neutropenia, which was longer among patients who failed or developed breakthrough bacteremia than among those who responded to monotherapy. Initial empirical antibiotic therapy with cefepime as a single agent in patients with febrile neutropenia and a hematological malignancy is effective, but patients with prolonged neutropenia appear to be

Common pathogens of clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) are viruses, such as influenza virus. However, bacteria are rare pathogens for MERS. We report the first patient with MERS associated with febrile urinary tract infection. A 16-year-old lupus patient was admitted to our hospital. She had fever, headache, vomiting, and right back pain. Urinary analysis showed leukocyturia, and urinary culture identified Klebsiella pneumoniae. Cerebrospinal fluid examination and brain single-photon emission computed tomography showed no abnormalities. Therefore, she was diagnosed with febrile urinary tract infection. For further examinations, 99mTc-dimercaptosuccinic acid renal scintigraphy showed right cortical defects, and a voiding cystourethrogram demonstrated right vesicoureteral reflux (grade II). Therefore, she was diagnosed with right pyelonephritis. Although treatment with antibiotics administered intravenously improved the fever, laboratory findings, and right back pain, she had prolonged headaches, nausea, and vomiting. T2-weighted, diffusion-weighted, and fluid attenuated inversion recovery images in brain magnetic resonance imaging showed high intensity lesions in the splenium of the corpus callosum, which completely disappeared 1 week later. These results were compatible with MERS. To the best of our knowledge, our patient is the first patient who showed clinical features of MERS associated with febrile urinary tract infection. In patients with pyelonephritis and an atypical clinical course, such as prolonged headache, nausea, vomiting, and neurological disorders, the possibility of MERS should be considered.

Evaluating the febrile patient with a rash.

McKinnon, H D; Howard, T

The differential diagnosis for febrile patients with a rash is extensive. Diseases that present with fever and rash are usually classified according to the morphology of the primary lesion. Rashes can be categorized as maculopapular (centrally and peripherally distributed), petechial, diffusely erythematous with desquamation, vesiculobullous-pustular and nodular. Potential causes include viruses, bacteria, spirochetes, rickettsiae, medications and rheumatologic diseases. A thorough history and a careful physical examination are essential to making a correct diagnosis. Although laboratory studies can be useful in confirming the diagnosis, test results often are not available immediately. Because the severity of these illnesses can vary from minor (roseola) to life-threatening (meningococcemia), the family physician must make prompt management decisions regarding empiric therapy. Hospitalization, isolation and antimicrobial therapy often must be considered when a patient presents with fever and a rash.

Full Text Available Objective: The aim of this study is to investigate if neutrophil CD64 expression in febrile neutropenia patients could be used as an early indicator of bacteremia. Materials and Methods: All consecutive patients older than 18 years of age who had developed febrile neutropenia episodes due to hematological malignancies were included in the study. Those patients who had significant growth in their blood cultures constituted the case group, while those who had febrile neutropenia without any growth in their cultures and who did not have any documented infections formed the control group. Blood culture bottles were incubated in the Bact ALERT 3D system (bioMerieux, France, identification and susceptibility testing were performed using an automated broth microdilution method (VITEK 2, bioMerieux, and CD64 expression analysis was performed by the flow cytometry method. C-reactive protein (CRP was measured by turbidimetric methods (Biosystems, Spain and erythrocyte sedimentation rate (ESR was measured by the Wintrobe method. Results: In total, we prospectively evaluated 31 febrile episodes. The case group consisted of 17 patients while the control group included 14 patients. CD64 was found on neutrophils of the case group patients with a mean count of 8006 molecules/cell and of control group with a mean count of 2786 molecules/cell. CD64 levels of the case group were significantly higher than those of the control group (p=0.005. In the differentiation of the case group from the control group, a 2500 cut-off value for CD64 had significant [AUC=0.792 (0.619-0.965] predictive value (p=0.001. In the prediction of patients with a 2500 cut-off value for CD64, sensitivity was 94.1%, positive predictive value was 76.2%, specificity was 64.3%, and negative predictive value was 90.0%. CRP levels and ESR values did not differ significantly between the groups (p=0.005. Conclusion: Neutrophil CD64 expression could be a good predictor as an immune parameter with

Infant mortality in rural areas of Nigeria can be minimized if childhood febrile conditions are treated by trained health personnel, deployed to primary healthcare centres (PHCs) rather than the observed preference of mothers for patent medicine dealers (PMDs). However, health service utilization/patronage is driven by consumer satisfaction and perception of services/product value. The objective of this study was to determine 'mothers' perception of recovery' and 'mothers' satisfaction' after PMD treatment of childhood febrile conditions, as likely drivers of mothers' health-seeking behaviour, which must be targeted to reverse the trend. Ugwuogo-Nike, in Enugu, Nigeria, has many PMDs/PHCs, and was selected based on high prevalence of childhood febrile conditions. In total, 385 consenting mothers (aged 15-45 years) were consecutively recruited at PMD shops, after purchasing drugs for childhood febrile conditions, in a cross-sectional observational study using a pre-tested instrument; 33 of them (aged 21-47 years) participated in focus group discussions (FGDs). Qualitative data were thematically analysed while a quantitative study was analysed with Z score and Chi square statistics, at p perceived that their child had delayed recovery, but were satisfied with PMDs' treatment of childhood febrile conditions, for reasons that included politeness, caring attitude, drug availability, easy accessibility, flexibility in pricing, shorter waiting time, their God-fearing nature, and disposition as good listeners. Mothers' satisfaction with PMDs' treatment is significantly (p satisfaction with PMDs' treatment from a knowledge of mothers' perception of recovery shows a high accord (lambda[A from B] = 0.8727), unlike when predicting mothers' perception of recovery based on knowledge of mothers' satisfaction with PMDs' treatment (lambda[A from B] = 0.4727). Mothers' satisfaction could be the key 'driver' of mothers' health-seeking behaviour and is less likely to be

Clinical studies have indicated that transient hypotension can occur after propacetamol administration. This study aimed to analyze the hemodynamic changes after propacetamol administration in patients visiting the ED due to febrile UTI. We also examined the incidence of propacetamol-induced hypotension and compared the clinical characteristics of patients with persistent hypotension, defined as requiring additional fluids or vasopressors, to those with transient hypotension. A retrospective analysis of the electronic medical records of patients who visited the ED between June 2015 and May 2016, were diagnosed with febrile UTI, and treated with propacetamol, was conducted. We included 195 patients in this study; of these, 87 (44.6%) showed hypotension. In all patients, significant decreases in systolic blood pressure (SBP; 135.06±20.45mmHg vs 117.70±16.41mmHg), diastolic blood pressure (DBP; 79.74±12.17mmHg vs 69.69±10.96mmHg), and heart rate (97.46±17.14mmHg vs 90.72±14.90mmHg) were observed after propacetamol administration. The basal SBP and DBP were higher in the hypotension than in the non-hypotension group (basal SBP: 144.4±22.3mmHg vs 127.6±15.3mmHg; basal DBP: 83.3±12.6mmHg vs 76.9±11.0mmHg). Patients with persistent hypotension had a lower baseline BP, which was not elevated despite fever, and a higher rate of bacteremia than those with transient hypotension. Although febrile UTI patients treated with propacetamol in the ED showed hemodynamic changes, these changes did not have a large effect on their prognosis. However, in patients who showed bacteremia or a normal initial BP despite fever, the possibility of developing persistent hypotension should be considered. Copyright © 2017.

In Papua New Guinea the aetiology of febrile illnesses remains poorly characterized, mostly due to poor diagnostic facilities and the inaccessibility of much of the rural areas of the country. We investigated the aetiological agents of febrile illnesses for 136 people presenting to Wipim Health Centre in Western Province, Papua New Guinea. Arboviral and rickettsial real-time polymerase chain reaction (PCR) assays, malaria blood smears and a malaria PCR test were used to identify pathogens associated with a history of fever. In 13% (n = 18) of cases an aetiological agent was identified. Dengue virus type 1 was detected in 11% (n = 15) of the samples tested and malaria in 2% (n = 3). None of the other arboviral or rickettsial pathogens tested for were detected in any of the samples. Although dengue viruses have been identified in Papua New Guinea using serological methods, this study represents the first direct detection of dengue in the country. The detection of malaria, on the other hand, was surprisingly low considering the previous notion that this was a hyperendemic region of Papua New Guinea.

To evaluate the accuracy of an acute (99m)Tc-dimercaptosuccinic acid (DMSA) scan in predicting dilating vesicoureteral reflux (VUR) among young children with a febrile urinary tract infection (UTI). The medical records of children (≤ 2 years of age), presenting with febrile UTI between January 2000 and December 2011, were retrospectively reviewed. A total of 523 children were included in this study, of whom 397 children (75.9%) had abnormal DMSA results and 178 children (34.0%) were identified as VUR on micturating cystourethrography (MCU). Among all the patients, the number of children with dilating VUR was 151 (28.9%). The rate of abnormal results on DMSA for the dilating VUR group was significantly higher than the rates for the non-VUR and low-grade VUR groups (P UTI, an acute DMSA scan is valuable in the exclusion of dilating VUR. The likelihood of the presence of dilating VUR on MCU is rather low when the result of DMSA is negative. DMSA should be conducted to assess the need for an MCU.

Urinary Tract Infection (UTI) is a common cause of bacterial infection in young children, and accounts for a significant number of pediatric hospitalizations. To review recent publications focusing on the care of children hospitalized with their first febrile UTI. A PubMed search was performed including publications from 2011-2016 on first febrile UTI in childhood. Abstracts were reviewed for being relevant to the care of hospitalized children and their follow-up. Relevant articles underwent full review by all authors and articles excluded from results included those without novel data analysis, primary improvement-based reports and studies with poor design or analysis. Included articles were categorized as "diagnosis", "management", "imaging" or "follow-up". Of 406 articles initially identified, 40 studies were included. One technical report with a systematic review was also included. Major topics addressed included the role of urinalysis in screening for UTI, use of parenteral antimicrobial therapy, the role of antimicrobial prophylaxis in prevention of recurrent UTI, and ideal follow-up and imaging approach following diagnosis of febrile UTI. Recent literature on first febrile UTI addresses a broad range of areas regarding the care of hospitalized children, though some questions remain unanswered. Overall, studies support increased attention to the potential risks, expense and invasiveness of various approaches for evaluation. Proposed updates to practice included: utilization of urinalysis for screening and diagnosis, transitioning to oral antimicrobials based on clinical improvement and limiting the routine use of voiding cystourethrogram and antimicrobial prophylaxis.

Complement reduction impairs the febrile response of guinea pigs to endotoxin.

Sehic, E; Li, S; Ungar, A L; Blatteis, C M

Although it is generally believed that circulating exogenous pyrogens [e.g., lipopolysaccharides (LPS)] induce fever via the mediation of endogenous pyrogens (EP) such as cytokines, the first of these, tumor necrosis factor-alpha, is usually not detectable in blood until at least 30 min after intravenous administration of LPS, whereas the febrile rise begins within 15 min after its administration. Moreover, although abundant evidence indicates that circulating LPS is cleared primarily by liver macrophages [Kupffer cells (KC)], these do not secrete EP in immediate response. This would imply that other factors, presumably evoked earlier than EP, may mediate the onset of the febrile response to intravenous LPS. It is well known that blood-borne LPS very rapidly activates the intravascular complement (C) system, some components of which in turn stimulate the quick release into blood of various substances that have roles in the acute inflammatory reaction. KC contain receptors for C components and are in close contact with afferent vagal terminals in the liver; the involvement of hepatic vagal afferents in LPS-induced fever has recently been shown. In this study, we tested the hypothesis that the initiation of fever by intravenous LPS involves, sequentially, the C system and KC. To test this postulated mechanism, we measured directly the levels of prostaglandin E2 (PGE2) in the interstitial fluid of the preoptic anterior hypothalamus (POA), the presumptive site of the fever-producing controller, of conscious guinea pigs over their entire febrile course, before and after C depletion by cobra venom factor (CVF) and before and after elimination of KC by gadolinium chloride (GdCl3). CVF and GdCl3 pretreatment each individually attenuated the first of the biphasic core temperature (Tc) rises after intravenous LPS, inverted the second into a Tc fall, and greatly reduced the usual fever-associated increase in POA PGE2. We conclude, therefore, that C activation may indeed be

El dolor cráneofacial es inducido frecuentemente por isquemia cardíaca. Esta causa debe tenerse en cuenta en el diagnóstico diferencial del dolor dental y orofacial. Implicaciones clínicas. Debido a que los pacientes que tienen un IAM sin dolor torácico corren un mayor riesgo de no ser correctamente diagnosticados y de muerte, el alerta del clínico sobre esta sintomatología puede ser crucial para el diagnóstico precoz y un rápido tratamiento

Recent studies have shown changes in the aetiology of serious bacterial infections in febrile infants ≤ 90 days of age. The aim of this study was to describe the current microbiology and outcomes of these infections in Spain. Sub-analysis of a prospective multicentre study focusing on febrile infants of less than 91 days of life, admitted between October 2011 and September 2013 to Emergency Departments of 19 Spanish hospitals, members of the Spanish Paediatric Emergency Research Group of the Spanish Society of Paediatric Emergencies (RISeuP/SPERG). The analysis included 3,401 febrile infants ≤90 days of age with fever without source. There were 896 positive cultures: 766 urine (85.5%), 100 blood (11.2%), 18 cerebrospinal fluid (2%), 10 stool, and 2 umbilical cultures. Among the 3,401 infants included, 784 (23%) were diagnosed with a serious bacterial infection, and 107 of them (3.1%) with an invasive infection. E. coli was the most common pathogen isolated from urine (628; 82%), blood (46; 46%), and cerebrospinal fluid cultures (7; 38.9%), followed by S. agalactiae that was isolated from 24 (24%) blood cultures and 3 (16.7%) cerebrospinal fluid cultures. There were only 2 L. monocytogenes infections. Four children died, and seven had severe complications. Among infants ≤ 90 days of age with fever without source, E. coli was the most common pathogen isolated from urine, blood, and cerebrospinal fluid cultures.

A traditional Chinese herbal medicine, Kampo medicine, maoto, has been widely used in the treatment of febrile symptoms caused by viral infection. This herbal extract granule for oral use, however, is not well accepted by infants or young children due to its unpleasant taste and odor. Therefore, we prepared Kampo medicine, maoto, suppository and investigated the pharmaceutical and clinical efficacy of the suppository. Kampo medicine, maoto, granules were micro-pulverized and homogeneously dispersed into Hosco-H15 to prepare suppositories containing 0.25 to 1.0 g herbal extract by the conventional fusion method. Content of l-ephedrine, an index compound of Kampo medicine, maoto, in the extract granules and suppositories was determined by using a high performance liquid chromatographic method. Physicochemical experiments revealed that the suppository containing 0.5 g herbal extract had the most suitable melting point of 34 degrees C. Contents of l-ephedrine in the suppository were constant, 93-96% of those in the same amount of the extract granules in different three lots. Upper and lower portions of the suppository had the same content of l-ephedrine. The suppository maintained more than 95% of l-ephedrine content through 6 months at 4 degrees C, room temperature and 40 degrees C, although maldistribution of the extract constituent was observed after storage at 40 degrees C. The suppository was administered to 21 pediatric febrile patients at a dose of 1/3 to 2 full pieces depending on their body weight and physical status. Significant reduction (pchildren with viral febrile symptoms without any adverse effects.

El objetivo de esta investigación fue contrastar la efectividad de 4 métodos de evaluación de riesgo de infección bacteriana grave (IBG en recién nacidos (RN febriles, uno de los cuales fue desarrollado por los autores del trabajo y los otros son los utilizados en la práctica internacional. MÉTODOS. Se realizó un estudio descriptivo, retrospectivo y aplicado de 1358 RN febriles sin signos de focalización evaluados y clasificados por riesgo de IBG. Fue aplicado el método propuesto por los autores, que comprende: antecedente de ser sano; ausencia de impresión médica de un estado tóxico-infeccioso; ausencia de evidencias de infección focal en el examen físico; fiebre menor de 39 ºC y no persistente o recurrente; recuento de leucocitos sanguíneos > 5,0 x 10(9/L y < 20,0 x 10(9/L; velocidad de sedimentación globular < 20 mm/h y recuento de leucocitos en orina < 10 000/mL. Éste y los otros métodos se aplicaron en una evaluación inicial y al término de 48 h evolutivas. Se calcularon los valores predictivos para los distintos métodos y se evaluó también la efectividad mediante la función de ganancia. RESULTADOS. La frecuencia de IBG fue del 20,4 %. La causa más frecuente fue la infección del tracto urinario. De los 652 RN evaluados inicialmente por nuestro método, hubo cambio de categoría evolutiva en 177 (13,0 %; con los otros métodos también ocurrieron cambios, menos notables. Los fallos de los valores predictivos con nuestro método fueron 40 (8,5 %, una proporción significativamente menor (p < 0,001 que con los otros métodos. La función de ganancia tuvo valores aritméticos superiores con los otros métodos. CONCLUSIONES. Existe un mayor margen de seguridad con nuestro método en relación con los otros métodos de evaluación estudiados. Atribuimos esta ventaja al hecho de que se incluyeron parámetros evaluativos clínicos y de laboratorio (como la magnitud y persistencia de la fiebre y el aspecto

Full Text Available Tularaemia is a highly contagious infectious zoonosis caused by the bacterial agent Francisella tularensis. The aim of this study was to investigate the presence of antibodies to F. tularensis in febrile patients in northeastern Kenya. During 2014–2015, 730 patients were screened for anti-F. tularensis antibodies using a combination of ELISA and Western blot. Twenty-seven (3.7% individuals were positive for F. tularensis. Tularaemia was not suspected by the treating clinicians in any of them. Our results suggest that tularaemia may be present in Kenya but remain unreported, and emphasizes the need for local clinicians to broaden their diagnostic repertoire when evaluating patients with undifferentiated febrile illness.

The optimal method of urine collection in febrile infants is debatable; catheterization, considered more accurate, is technically difficult and invasive. To determine predictors of urethral catheterization in febrile infants and to compare bag and catheterized urine test performance characteristics. Prospective analysis of infants enrolled in the Pediatric Research in Office Settings' Febrile Infant Study. A total of 219 practices from within the Pediatric Research in Office Settings' network, including 44 states, the District of Columbia, and Puerto Rico. A total of 3066 infants aged 0 to 3 months with temperatures of 38 degrees C or higher. We calculated adjusted odds ratios for predictors of catheterization. Diagnostic test characteristics were compared between bag and catheterization. Urinary tract infection was defined as pure growth of 100 000 CFU/mL or more (bag) and 20 000 CFU/mL or more (catheterization). Seventy percent of urine samples were obtained by catheterization. Predictors of catheterization included female sex, practitioner older than 40 years, Medicaid, Hispanic ethnicity, nighttime evaluation, and severe dehydration. For leukocyte esterase levels, bag specimens demonstrated no difference in sensitivity but somewhat lower specificity (84% [bag] vs 94% [catheterization], PInfection rates were similar in bag and catheterized specimens (8.5% vs 10.8%). Ambiguous cultures were more common in bag specimens (7.4% vs 2.7%, Purinary tract infection. Although both urine cultures and urinalyses are more accurate in catheterized specimens, the magnitude of difference is small but should be factored into clinical decision making.

Antimicrobial susceptibility and prevalence of pediatric urinary tract infection (UTI) is very useful for pediatricians in selecting effective antibiotics in time to improve outcomes in patients. This study aimed to determine the prevalence rate, bacterial distribution, and antimicrobial susceptibility of UTI in febrile young children at a teaching hospital in northern Taiwan. From January 2011 to December 2011, all urinary isolates from suspected cases of UTI in febrile young children aged from 1 day to 36 months visiting the Pediatric Emergency Room of Chang Gung Children's Hospital, Taoyuan, Taiwan were identified by conventional methods. Antibiotic susceptibility was determined according to the Clinical and Laboratory Standards Institute. A total of 5470 (78%) from 7009 eligible children were enrolled in the study, and 619 (11.3%) had a diagnosis of UTI. The most prevalent bacterium was Escherichia coli (68%) followed by Klebsiella pneumoniae (8.1%) and Proteus mirabilis (6.8%). Ampicillin, piperacillin, and trimethoprim-sulfamethoxazole (TMP-SMX) showed a higher resistance rate in the three predominant bacteria. All tested bacteria showed higher resistance to ampicillin (79.3%) and TMP-SMX (44.1%), and lower resistance to cefazolin (17.7%) and gentamicin (13.0%). Fourteen percent of the isolates produced extended spectrum β-lactamase (ESBL), among which 93.33% were E. coli isolates. The overall prevalence of UTI in this study was higher than previously reported in febrile children. Higher antimicrobial resistance was found in ampicillin and TMP-SMX. Among commonly used antibiotics, cefazolin and gentamicin are recommended to treat UTI in febrile children aged < 3 years without localizing signs. Copyright © 2015. Published by Elsevier B.V.

The aim of this article was to assess the usefulness of procalcitonin (PCT) as a marker for predicting dilating (grades III-V) vesicoureteral reflux (VUR) in young children with a first febrile urinary tract infection. Children ≤2 years of age with a first febrile urinary tract infection were prospectively evaluated. Serum samples were tested for PCT at the time of admission to a tertiary hospital. All children underwent renal ultrasonography (US), Tc-dimercaptosuccinic acid renal scan, and voiding cystourethrography. The diagnostic characteristics of PCT test for acute pyelonephritis and dilating VUR were calculated. Of 272 children analyzed (168 boys and 104 girls; median age, 5 months), 169 (62.1%) had acute pyelonephritis. There was VUR demonstrated in 97 (35.7%), including 70 (25.7%) with dilating VUR. The median PCT value was significantly higher in children with VUR than in those without (P predictors of dilating VUR. PCT is useful for diagnosing acute pyelonephritis and predicting dilating VUR in young children with a first febrile urinary tract infection. A voiding cystourethrography is indicated only in children with high PCT values (≥1.0 ng/mL) and/or abnormalities found on a US.

This randomized, dual-center study compared the efficacy and safety of piperacillin-tazobactam (PTZ) and imipenem-cilastatin (IMP) in hematopoietic stem cell transplantation (HSCT) recipients with febrile neutropenia. HSCT recipients with febrile neutropenia were randomized into two groups receiving either PTZ or IMP as initial empiric antibiotic. Endpoints were defervescence rate after empiric antibiotic for 48 h, success at end of therapy, and side effects. Defervescence within 48 h after empiric antibiotic was observed in 46 patients with PTZ (75.4%) and 59 patients with IMP (95.2%) (p = 0.002). Ten patients (10/46) in the PTZ group and two patients (2/59) in the IMP group switched empiric antibiotics due to recurrent fever (p = 0.005). Success of initial antibiotic with modification was achieved in 34 patients with PTZ (55.7%) and 53 patients with IMP (85.5%) at the end of therapy (p = 0.001). To treat the bacteremia, seven of 10 patients in the PTZ group and one of eight patients in the IMP group needed to switch the empiric antibiotic (p = 0.025). Compared with PTZ, IMP had more gastrointestinal adverse events (p = 0.045). This study demonstrates that IMP had better efficacy than PTZ as an empiric antibiotic for febrile neutropenia in the HSCT setting, but with more gastrointestinal side reactions. © 2015 John Wiley & Sons A/S.

Urinary tract infections (UTI) are a major public health problem among spinal cord injury (SCI) patients. They frequently involve multidrug-resistant (MDR) bacteria. Ceftolozane/tazobactam (C/T) is a novel antibiotic combination approved for complicated intra-abdominal and UTI caused by Gram-positive and Gram-negative organisms, including some MDR strains. Little is known about the use of this agent for complicated febrile UTI occurring among SCI patients with neurogenic bladder due to MDR Pseudomonas aeruginosa (PSA). We describe the case of a 35-year-old man with SCI due to multiple sclerosis, with a neurogenic bladder necessitating a bilateral nephrostomy and double J catheter, who developed a febrile UTI due to a MDR PSA, which was susceptible only to amikacin and colistin. Because of this MDR phenotype and the underlying kidney disease, a 1000 mg (1000 mg per 500 mg) dose of C/T was given as monotherapy every 8 h for 7 days, after 3 days of colistin and amikacin. Thanks to this treatment, the patient had a favorable outcome with no clinical signs of UTI or positive urine culture up to 1 month after diagnosis. C/T seems to be an effective and safe therapeutic option for febrile UTI due to MDR PSA in SCI patients with neurogenic bladder, even when administered in monotherapy for 10 days.

Full Text Available Introduction: In cancer patients various infections were developed due to severe neutropeniaresulted from chemotherapy. There is controversy between initial monotherapy or multidrugprescription. The purpose of this study was to compare the efficacy of ceftazidime and imipenem incontrol of fever in cancer patients with febrile neutropenia.Materials ands Methods: 40 patients with cancer, fever and neutropenia (PMN<500, withoutrecognized source of infection, were selected using the convenience and consecutive method. Using arandom sampling, twenty patients were treated with imipenem (500mg Iv/Q8hr and others withceftazidime (2mg Iv/Q8hr. The criteria for positive response to the drugs were: fever disappearanceduring maximally 72 hours lasted for up to 24 hours, and increased neutrophil counts more than500/ml.Results: Our results show that 60% and 55% patients with ceftazidime and imipenem were cured,respectively. 40% patients treated with ceftazidime and 45% patients treated with imipenem neededanother antibiotic therapy at the same time. No significant relationship was found between differenttypes of drug regime among the groups.Conclusion: Findings of this study indicate that ceftazidime and imipenem have similar efficacy intreatment of febrile neutropenic patients. Due to more availability and lower cost of ceftazidime thanimipenem, ceftazidime is suggested as first line treatment in febrile neutropenia.

Roultella ornithinolytica infection in infancy: a case of febrile urinary tract infection.

Raoultella ornithinolytica is a Gram-negative, non-motile, encapsulated, aerobic bacillus belonging to the Enterobacteriaceae family. R. ornithinolytica is a not very common, but emergent causal agent of human infection, and its expression of beta-lactamase provides resistance to commonly used antibiotics. The pathogenetic potential of R. ornithinolytica isolates in human disease has become increasingly important. Several cases of hospital-acquired infection, mostly associated with invasive procedures, or in patients with co-morbidity caused by R. ornithinolytica, have been previously reported in the adult population. In pediatric population, two cases in immunocompromised children, one case in an infant with visceral heterotaxy and one case of catheter-related bacteraemia are described. Here, we present the first case of febrile urinary tract infection due to R. ornithinolytica in an 8-month-old infant, recovered from a previous febrile UTI caused by E. coli and without co-morbidity. The empiric therapy with ceftriaxone, followed by cefpodoxime proxetil, resolved symptoms: the clinical condition of the infant improved rapidly and the treatment eradicated urine from the R. ornithinolytica infection. Since other pathogens rather than R. ornithinolytica are usually identified in children with urinary tract infections, including Escherichia coli, Proteus, Klebsiella and Pseudomonas, the identification of this microorganism in our patient's urine was also unexpected.

Leptospira spp., which comprise 3 clusters (pathogenic, saprophytic, and intermediate) that vary in pathogenicity, infect >1 million persons worldwide each year. The disease burden of the intermediate leptospires is unclear. To increase knowledge of this cluster, we used new molecular approaches to characterize Leptospira spp. in 464 samples from febrile patients in rural, semiurban, and urban communities in Ecuador; in 20 samples from nonfebrile persons in the rural community; and in 206 samples from animals in the semiurban community. We observed a higher percentage of leptospiral DNA-positive samples from febrile persons in rural (64%) versus urban (21%) and semiurban (25%) communities; no leptospires were detected in nonfebrile persons. The percentage of intermediate cluster strains in humans (96%) was higher than that of pathogenic cluster strains (4%); strains in animal samples belonged to intermediate (49%) and pathogenic (51%) clusters. Intermediate cluster strains may be causing a substantial amount of fever in coastal Ecuador.

Immunoadjuvants enhance the febrile responses of rats to endogenous pyrogen.

Stitt, J T; Shimada, S G

1989-11-01

The febrile responses of male Sprague-Dawley rats to a semipurified endogenous pyrogen produced from human monocytes were characterized by establishing fever dose-response curves. The animals were then injected intravenously with a number of substances that possessed the common properties of stimulating the phagocytic activity of the cells of the reticuloendothelial system and of acting as immunoadjuvants. The substances used were zymosan, lipopolysaccharide endotoxin, and muramyl dipeptide. Three days after any of these immunoadjuvants were injected, the fever sensitivity of the rats was remeasured. In each case, the slope of the fever dose-response curve tripled, and in some instances the response threshold for fever response was reduced by factors of three to eight. Furthermore, the maximum increase in body temperature produced by the endogenous pyrogen was more than doubled after immunoadjuvant treatment. By contrast latex beads, which are also phagocytized by the cells of the reticuloendothelial system but do not subsequently increase their phagocytic index nor do they enhance immune responses, had no effect on the fever sensitivity of rats in response to endogenous pyrogen. In the light of these findings, it is suggested that the febrile responses of rats to endogenous pyrogen are mediated in some manner by cells that possess some of the properties of reticuloendothelial cells. The location of these putative cells must be close to the circulation, because the immunoadjuvants used in this study were, for the most part, large molecular weight molecules that could not cross the blood-brain barrier easily.

Automated flow cytometry of urine remains an incompletely validated method to rule out urinary tract infection (UTI) in children. This cross-sectional analytical study was performed to compare the predictive values of flow cytometry and a dipstick test as initial diagnostic tests for UTI in febrile children and prospectively included 1,106 children (1,247 episodes). Urine culture was used as the gold standard test for diagnosing UTI. The performance of screening tests to diagnose UTI were established using receiver operating characteristic (ROC) analysis. Among these 1,247 febrile episodes, 221 UTIs were diagnosed (17.7% [95% confidence interval {CI}, 15.6 to 19.8%]). The area under the ROC curve for flow cytometry white blood cell (WBC) counts (0.99 [95% CI, 0.98 to 0.99]) was significantly superior to that for red blood cell (0.74 [95% CI, 0.70 to 0.78]) and bacterial counts (0.89 [95% CI, 0.87 to 0.92]) (P UTI in febrile children.

Saleem, L.; Zahid, N.A.

2017-01-01

Objective: To evaluate the association between serum albumin and risk of post chemotherapy febrile neutropenia. Study Design: Cross sectional study. Place and Duration of Study: Department of oncology, Liaquat National Hospital, from 1st Jan 2015 to 31st Dec 2016. Material and Method: One hundred and sixty-six biopsy proven cancer patients with Eastern cooperative oncology group (ECOG) performance status <2 and without significant co-morbidities received first cycle of chemotherapy during two years study period. Different chemotherapies with moderate to severe risk of FN were used. Patient's pre-treatment serum albumin was measured and patients followed for occurrence of FN. Association between serum albumin and post chemotherapy FN was analyzed. Results: Data of 166 patients was available for final analysis. Post chemotherapy FN was observed in 19.9% (33/166) patients. Pre-chemotherapy serum albumin level was <3.5 mg/dl in (35/166) 21.1% of patients, out of which (15/35) 42.9% developed FN. Serum albumin (p=0.0005) was highly significantly associated with a risk of FN. On analysis of other factors age, gender, body surface area (BSA) and pre-chemotherapy hemoglobin level were not significantly associated with a risk of FN while body mass index (p=0.0005) was found to be associated with risk of FN. Conclusion: Pre-chemotherapy serum albumin levels were found to be statistically significant predictor of postchemotherapy febrile neutropenia.

Macarena Gálvez Herrer

2003-07-01

Full Text Available Los estudios transculturales no son un ejercicio secundario y complementario en el estudio de la psicología; un modelo antropológico de la conducta humana obliga a plantear que las variables culturales no son secundarias sino primarias. Por estas razones el estudio del “burnout†o desgaste profesional puede profundizarse mediante la utilización de los métodos transculturales. No es suficiente con la simple comparación de resultados, sino que es necesario buscar instrumentos propios de cada cultura y establecer la comparación no sólo del síndrome de desgaste profesional sino de todos los diferentes elementos del proceso. El trabajo presentado establece las bases teóricas de este planteamiento, y expone, mediante un ejemplo, algunas de las vías posibles para una psicología transcultural del burnout.

Full Text Available INTRODUCCIÓN. La punción lumbar está indicada en la evaluación inicial del recién nacido febril sin signos de focalización. Sin embargo, esta puede resultar fallida y crear incertidumbre en el manejo del tratamiento antibiótico. Fue objetivo de este trabajo verificar el tratamiento y evolución de los recién nacidos febriles sin signos de focalización, cuando la punción lumbar resultó fallida en la evaluación inicial. MÉTODOS. Se estudiaron retrospectivamente 150 recién nacidos febriles sin signos de focalización y con punción lumbar fallida en la evaluación inicial, ingresados en el servicio de neonatología de nuestro hospital entre 1992 y el 2000. Todos los pacientes se clasificaron según criterios de bajo riesgo de infección bacteriana grave. El uso de tratamiento antibiótico estuvo sujeto a la consideración del médico que hizo la evaluación inicial. Se calcularon índice y tasa de punción lumbar fallida, se midió la relación entre la indicación de tratamiento antibiótico inicialmente y la clasificación de riesgo de infección bacteriana grave, y verificamos la evolución de los pacientes. RESULTADOS. Fueron fallidas 150 de 1174 punciones lumbares (8,5 % para un índice de 9,2. Los recién nacidos calificados de alto riesgo recibieron con mayor frecuencia tratamiento antibiótico (23,3 % en contraste con los catalogados de bajo riesgo, quienes fueron tratados predominantemente sin antibióticos (36,0 % (p = 0,03. Egresaron vivos 149 neonatos (99,3 %, tanto con uso de antibióticos como sin él. Sin embargo, hubo un fallecido clasificado de alto riesgo de infección bacteriana grave que recibió tratamiento antibiótico desde el inicio. CONCLUSIONES. La punción lumbar puede resultar fallida al evaluar a recién nacidos febriles sin signos de focalización. La indicación de tratamiento antimicrobiano en estos pacientes estuvo relacionada significativamente con la clasificación de riesgo de infección bacteriana

Full Text Available La postmodernidad exige para ser comprendida una dimensión sociohistórica y otra filosófica que le resulta irrenunciables. También hay una serie de fenómenos propiamente culturales, que son los que los denominados "estudios culturales" (G. Canclini. M. Barbero, etc. han asumido en Latinoamérica. Tales estudios han aportado una descripción de fenómenos nuevos, que no son analizados por ningún otro discurso teórico (tribus urbanas, identidades lábiles, influencia de los medios en los nuevos estilos de consumo, etc.. Con ello se da cuenta de parte de la cuestión postmodernidad, pero sin dudase deja fuera otras: lo filosófico y aún lo social y lo político quedan fuera de esa especie de antropología del presente. Por lo tanto, un enfoque integral de lo postmoderno incluye los estudios culturales, pero está lejos de limitarse a ellos.

We assessed nasopharyngeal (NP) carriage of five pathogens in febrile children with and without acute respiratory infection (ARI) of the upper (URTI) or lower tract, attending health facilities in Tanzania. NP swabs collected from children (N = 960) aged 2 months to 10 years, and with a temperature ≥38°C, were utilized to quantify bacterial density of S. pneumoniae (Sp), H. influenzae (Hi), M. catarrhalis (Mc), S. aureus (Sa), and N. meningitidis (Nm). We determined associations between presence of individual species, densities, or concurrent carriage of all species combination with respiratory diseases including clinical pneumonia, pneumonia with normal chest radiography (CXR) and endpoint pneumonia. Individual carriage, and NP density, of Sp, Hi, or Mc, but not Sa, or Nm, was significantly associated with febrile ARI and clinical pneumonia when compared to febrile non-ARI episodes. Density was also significantly increased in severe pneumonia when compared to mild URTI (Sp, p<0.002; Hi p<0.001; Mc, p = 0.014). Accordingly, concurrent carriage of Sp+, Hi+, and Mc+, in the absence of Sa- and Nm-, was significantly more prevalent in children with ARI (p = 0.03), or clinical pneumonia (p<0.001) than non-ARI, and in children with clinical pneumonia (p = 0.0007) than URTI. Furthermore, Sp+, Hi+, and Mc+ differentiated children with pneumonia with normal CXR, or endpoint pneumonia, from those with URTI, and non-ARI cases. Concurrent NP carriage of Sp, Hi, and Mc was a predictor of clinical pneumonia and identified children with pneumonia with normal CXR and endpoint pneumonia from those with febrile URTI, or non-ARI episodes.

El objetivo es evaluar características cualitativas de las habilidades en 2 tipos de procedimientos técnicos básicos al alcance de un cirujano general. Material y Métodos: estudio preliminar exploratorio observacional prospectivo en un Hospital Universitario consistente en la observación de los pasos de una toracotomía axilar o una dermolipectomía abdominal anterior con neo ombligo. Se analizó la práctica de las operaciones programadas, no discriminando que médicos residentes las habían efectuado. Los datos se medían en una lista de cotejos con una escala tipo Likert modificada de 3 items. Cada paso de la técnica observada era evaluado sin considerar el tiempo de duración de cada maniobra. Los evaluadores eran ajenos al equipo quirúrgico actuante ubicados donde no se los veía (en miradores para evitar sesgos o maniobras que afectaran la actividad. Se usaron pruebas estadísticas de ANOVA y prueba de t para detectar validez y diferencias en los resultados. Resultados: observada una toracotomía, todos los pasos quirúrgicos fueron evaluados por encima del valor 2 (bueno, sin variaciones en el desarrollo de cada paso ni existir diferencias significativas en la comparación de destrezas. Similares resultados se hallaron en la observación de la otra técnica. Conclusiones: con un sencillo método de observación directa inadvertida por el evaluado con criterios específicos se hizo un diagnóstico de situación demostrando la existencia de habilidades adquiridas en cirujanos en formación durante programas de residencia.

Improving early diagnosis of pulmonary infections in patients with febrile neutropenia using low-dose chest computed tomography.

Full Text Available We performed a prospective study in patients with chemotherapy induced febrile neutropenia to investigate the diagnostic value of low-dose computed tomography compared to standard chest radiography. The aim was to compare both modalities for detection of pulmonary infections and to explore performance of low-dose computed tomography for early detection of invasive fungal disease. The low-dose computed tomography remained blinded during the study. A consensus diagnosis of the fever episode made by an expert panel was used as reference standard. We included 67 consecutive patients on the first day of febrile neutropenia. According to the consensus diagnosis 11 patients (16.4% had pulmonary infections. Sensitivity, specificity, positive predictive value and negative predictive value were 36%, 93%, 50% and 88% for radiography, and 73%, 91%, 62% and 94% for low-dose computed tomography, respectively. An uncorrected McNemar showed no statistical difference (p = 0.197. Mean radiation dose for low-dose computed tomography was 0.24 mSv. Four out of 5 included patients diagnosed with invasive fungal disease had radiographic abnormalities suspect for invasive fungal disease on the low-dose computed tomography scan made on day 1 of fever, compared to none of the chest radiographs. We conclude that chest radiography has little value in the initial assessment of febrile neutropenia on day 1 for detection of pulmonary abnormalities. Low-dose computed tomography improves detection of pulmonary infiltrates and seems capable of detecting invasive fungal disease at a very early stage with a low radiation dose.

Zahid, K.F.; Hafeez, H.; Afzal, A.

2009-01-01

The aim of this study was to study trends in bacterial spectrum and susceptibility patterns of pathogens in adult febrile neutropenic patients during two time periods. We retrospectively reviewed the medical records of 379 adult oncology patients admitted with chemotherapy induced febrile neutropenia at our institute during years 2003 and 2006. A total of 151 organisms were isolated during the two calendar years. Gram negative bacteria accounted for 57.6% of organisms, while gram positive organisms accounted for 42.3% of the total isolates. The most common organisms were: Escherichia coli (23.1%), Staphylococcus epidermidis (13.9%), Pseudomonas aeruginosa (12.5%) and Staphylococcus aureus (7.9%). The number of gram positive isolates showed an increase from 35% in 2003 to 47.2% in 2006 (p=0.13). During each calendar year, Staphylococcus epidermidis and Staphylococcus aureus were 100% susceptible to vancomycin and 33% strains of Staphylococcus aureus were methicillin resistant. Escherichia coli and Pseudomonas aeruginosa strains were highly sensitive to piperacillin/tazobactam and amikacin during both time periods. Resistance of Pseudomonas aeruginosa strains to ciprofloxacin increased from 0% in 2003 to 50% in 2006 (p=0.03). Gram negative organisms are the predominant organisms in adult febrile neutropenic patients at our institute. Initial empirical therapy with piperacillin/tazobactam seems appropriate to cover most gram negative pathogens while vancomycin to be added for suspected gram positive infections. During the two calendar years resistance of Pseudomonas aeruginosa strains to ciprofloxacin has significantly increased. (author)

Despite success rates favoring ureteroneocystostomy over subureteral injection of dextranomer/hyaluronic acid for correction of vesicoureteral reflux, the reported incidence of postoperative febrile urinary tract infection favors the latter. We evaluated contemporary treatment cohorts for an association between correction of vesicoureteral reflux and risk of postoperative febrile urinary tract infection. We retrospectively reviewed the records of 396 consecutive patients who underwent ureteroneocystostomy or subureteral injection of dextranomer/hyaluronic acid between 1994 and 2008. Time to event multivariate analyses included preoperative grade of vesicoureteral reflux and bladder/bowel dysfunction. Of 316 patients meeting study criteria 210 underwent ureteroneocystostomy (356 ureters) and 106 underwent subureteral injection of dextranomer/hyaluronic acid (167). Median patient age was 5.7 years (IQR 3.4 to 8.3). Median followup was 28 months (IQR 8 to 61). Ureteral success was significantly greater after ureteroneocystostomy (88%, 314 of 356 cases) vs subureteral injection of dextranomer/hyaluronic acid (74%, 124 of 167, p = 0.0001). When controlling for preoperative grade of vesicoureteral reflux and bladder/bowel dysfunction, the risk of persistent reflux was 2.8 times greater after subureteral injection of dextranomer/hyaluronic acid (95% CI 1.7-4.7, p acid (4%, 4 of 106; HR 1.96, 95% CI 0.64-5.9, p = 0.24) even when controlling for preoperative grade of vesicoureteral reflux, a predictor of postoperative febrile urinary tract infection on multivariate analysis (HR 2.2 per increase in grade, 95% CI 1.3-3.6, p = 0.0022). Persistent reflux was not a predictor of postoperative febrile urinary tract infection (HR 0.81, 95% CI 0.22-2.9, p = 0.75 for ureteroneocystostomy vs HR 1.8, 95% CI 0.2-17.3, p = 0.6 for subureteral injection of dextranomer/hyaluronic acid and HR 1.8, 95% CI 0.3-3.3, p = 0.6 for both).

Full Text Available Introducción: El dengue es la infección transmitida por mosquitos más importante en el mundo. Siendo más susceptible a infectarse la población infantil. En la etapa inicial de la enfermedad los síntomas son indiferenciables de otros síndromes febriles agudos, situación que hace complejo, tardío y poco sensible el diagnóstico clínico en la fase aguda de la enfermedad. La prueba torniquete es utilizada como un criterio de clasificación para definir la severidad del dengue hemorrágico por la Organización Mundial de la Salud, podría utilizarse en el diagnóstico diferencial del dengue. Objetivo: Evaluar en población infantil las características operativas de la prueba torniquete en el diagnóstico diferencial del dengue de otros síndromes febriles agudos. Métodos: Entre junio de 2006 y Abril del 2008 se incluyeron del servicio de urgencias pacientes entre dos y 12 años de edad que presentaban un cuadro febril sin origen aparente. Se les realizó un examen físico estandarizado junto con la prueba de torniquete, calculándose la sensibilidad, especificidad, valor predictivo positivo (VPP y negativo (VPN a la prueba. Resultados: Se captaron 129 pacientes y se diagnosticaron 66 casos de dengue. La prueba torniquete tuvo sensibilidad de 60.6% (IC95%=48.8-72.4, especificidad 55.9% (IC95%=43.3-68.6, VPP 60.6% (IC95%=48.8-72.4 y un VPN 55.9%. (IC95%=43.3-68.6. El resultado de la prueba estuvo asociado al tiempo de tolerancia del torniquete (p<0.001. Conclusiones: La prueba torniquete por sí sola no es útil como herramienta clínica para diferenciar el dengue de otros síndromes febriles en niños entre los dos y los 12 años de zonas endémicas.

The efficacy and utility of continuous antibiotic prophylaxis (CAP) in children with congenital antenatal hydronephrosis (ANH) is uncertain. The literature has both supportive and contradictory evidence. The growing trend not to place children with ANH on CAP has created varied clinical practice based on anecdotal individual case characteristics. Our goal was to compare individual infant characteristics between those children who were maintained on CAP to those that were not to try to determine predisposing risk factors to febrile. All electronic medical records (EMRs) of children referred to our institution for congenital ANH over a period from 2001 to 2011 were examined. We excluded those referred for urinary tract infection (UTI) who had a history of congenital ANH. We also excluded those with incomplete records, or follow-up less than 2 years. Children were divided into two groups: those maintained on CAP (YCAP) and those not maintained on CAP (NCAP). Our primary endpoint was febrile UTI. Follow-up was at least 24 months. Demographic, perinatal and postnatal clinical data were recorded. Statistical analysis was performed using STATA Version 11.1. Of the 405 children fitting inclusion criteria, 278 (68.6%) children were maintained on CAP and 127 (31.4%) were not on CAP. The incidence of prematurity, oligohydramnios, perinatal respiratory complications, use of perinatal antibiotics, circumcision status, renal anomalies, associated medical diagnoses, and low birth weight did not differ between the two groups. Overall the incidence of febrile UTI during the follow-up period was 22.2%. The incidence of febrile UTI between the YCAP and NCAP groups was significant (YCAP = 7.9% and NCAP 18.7%, p = 0.021). Multivariate logistic regression using CAP as the dichotomous dependent variable revealed that ureteral dilation, high-grade vesicoureteral reflux (VUR), and ureterovesical junction (UVJ) obstruction were independent risk factors for febrile UTI.

Full Text Available Los estudios transculturales no son un ejercicio secundario y complementario en el estudio de la psicología; un modelo antropológico de la conducta humana obliga a plantear que las variables culturales no son secundarias sino primarias. Por estas razones el estudio del “burnout” o desgaste profesional puede profundizarse mediante la utilización de los métodos transculturales. No es suficiente con la simple comparación de resultados, sino que es necesario buscar instrumentos propios de cada cultura y establecer la comparación no sólo del síndrome de desgaste profesional sino de todos los diferentes elementos del proceso. El trabajo presentado establece las bases teóricas de este planteamiento, y expone, mediante un ejemplo, algunas de las vías posibles para una psicología transcultural del burnout

The Importance of Serum Cytokine Levels in Febrile Neutropenia

Directory of Open Access Journals (Sweden)

Nuray Buyukberber

2003-02-01

Full Text Available The most important evaluation of the neutropenic patients is to determine the risk group. The desired approach to patients with low risks should be either not to hospitalize or to hospitalize for a short period of time which both decreases the cost and exposure to the resistant flora. The early diagnosis of sepsis in patients with high risk may be life saving. Recently, the determination of low and high-risk groups only by the clinical variables is not found to be a reliable method. The laboratory parameters supported by the clinical variables may be more practical. The determination of serum cytokines levels in febrile neutropenia may be helpful for the early risk diagnosis, new treatment approaches, and prognosis.

Full Text Available A two-year-old spayed female mixed-breed dog was presented with a five-day history of hemorrhagic gastroenteritis and fever. On physical examination, the dog was lethargic and clinically dehydrated. The skin of the entire ventral abdomen extending to both flanks was erythematous, swollen and painful on palpation. Histopathological examination of skin biopsies revealed a severe diffuse neutrophilic dermatitis and panniculitis, resembling the subcutaneous form of Sweet’s syndrome in humans. A large part of the skin lesion developed full-thickness necrosis. After intensive care, three surgical wound debridements and wound adaptations, the wound healed by secondary intention within ten weeks. In the absence of infection of the skin or neoplasia, a diagnosis of neutrophilic dermatosis and panniculitis, resembling the subcutaneous form of acute febrile neutrophilic dermatosis, was made.

Risk factors for febrile urinary tract infection in infants with prenatal hydronephrosis: comprehensive single center analysis.

Zareba, Piotr; Lorenzo, Armando J; Braga, Luis H

2014-05-01

We assessed risk factors for urinary tract infection in children with prenatal hydronephrosis We identified 376 infants with prenatal hydronephrosis in an institutional database. The occurrence of febrile urinary tract infection in the first 2 years of life was ascertained by chart review. Febrile urinary tract infection was defined as a positive culture from a catheterized urine specimen in a patient with a fever of 38.0C or greater. Multivariate logistic regression was used to assess gender, circumcision status, hydronephrosis grade, vesicoureteral reflux grade and antibiotic prophylaxis as predictors of the risk of urinary tract infection. Included in analysis were 277 males and 99 females. Hydronephrosis was high grade in 128 infants (34.0%) and vesicoureteral reflux was present in 79 (21.0%). Antibiotic prophylaxis was prescribed in 60.4% of patients, preferentially to females vs males (70.7% vs 56.7%), those with high vs low grade hydronephrosis (70.3% vs 55.2%) and those with vs without vesicoureteral reflux (96.2% vs 50.8%). On multivariate analysis there was an association between high grade hydronephrosis and an increased risk of urinary tract infection (adjusted OR 2.40, 95% CI 1.26-4.56). Females (adjusted OR 3.16, 95% CI 0.98-10.19) and uncircumcised males (adjusted OR 3.63, 95% CI 1.18-11.22) were also at higher risk than circumcised males. Antibiotic prophylaxis was not associated with a decreased risk of urinary tract infection (adjusted OR 0.93, 95% CI 0.45-1.94). High grade hydronephrosis, female gender and uncircumcised status in males are independent risk factors for febrile urinary tract infection in infants with prenatal hydronephrosis. Antibiotic prophylaxis did not reduce the risk of urinary tract infection in the study group. Copyright © 2014 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

We examined the ability of a procalcitonin (PCT) protocol to detect vesicoureteral reflux (VUR) and renal scarring (RS), evaluated procedural costs and radiation burden, and compared four representative guidelines for children with their first febrile urinary tract infection (UTI). Children aged ≤2 years with their first febrile UTI who underwent renal ultrasonography (US), acute and late technetium-99m ((99m)Tc)-dimercaptosuccinic acid scan, and voiding cystourethrography were prospectively studied. The representative guidelines applied in a retrospective simulation included the American Academy of Pediatrics (AAP), National Institute of Clinical Excellence, top-down approach (TDA), and Italian Society of Pediatric Nephrology (ISPN). These were compared in terms of ability to detect abnormalities, procedural costs and radiation. Of 278 children analyzed, 172 (61.9%) had acute pyelonephritis. There was VUR in 101 (36.3%) children, including 73 (26.3%) with grades III-V VUR. RS was identified in 75 (27.0%) children. To detect VUR, TDA and PCT had the highest sensitivity for grades I-V VUR (80.2%) and III-V VUR (94.5%), respectively, whereas AAP had the highest specificity for I-V VUR (77.4%) and III-V VUR (78.0%), respectively. TDA and PCT had the highest sensitivity (100%) for detecting RS. The highest cost and radiation dose was associated with TDA, whereas AAP had the least expenditure and radiation exposure. By multivariate analysis, PCT and VUR, especially grades III-V, were independent predictors of RS. There is no perfect guideline for first febrile UTI children. The PCT protocol has good ability for detecting high-grade VUR and RS. If based on available imaging modalities and reducing cost and radiation burden, clinical suggestions in the AAP guidelines represent a considerable protocol.

To compare the diagnostic sensitivity, costs and radiation doses of imaging tests algorithms developed by the Argentine Society of Pediatrics in 2003 and 2015, against British and American guidelines after the first febrile urinary tract infection (UTI). Inclusion criteria: children ≤ 2 years old with their first febrile UTI and normal ultrasound, voiding cystourethrography and dimercaptosuccinic acid scintigraphy, according to the algorithm established by the Argentine Society of Pediatrics in 2003, treated between 2003 and 2010. The comparisons between algorithms were carried out through retrospective simulation. Eighty (80) patients met the inclusion criteria; 51 (63%) had vesicoureteral reflux (VUR); 6% of the cases were severe. Renal scarring was observed in 6 patients (7.5%). Cost: ARS 404,000. Radiation: 160 millisieverts. With the Argentine Society of Pediatrics' algorithm developed in 2015, the diagnosis of 4 VURs and 2 cases of renal scarring would have been missed. The cost of this omission would have been ARS 301,800 and 124 millisieverts of radiation. British and American guidelines would have missed the diagnosis of all VURs and all cases of renal scarring, with a related cost of ARS 23,000 and ARS 40,000, respectively and 0 radiation. Intensive protocols are highly sensitive to VUR and renal scarring, but they imply high costs and doses of radiation, and result in questionable benefits. Sociedad Argentina de Pediatría

Full Text Available To determine the involvement of oxidative stress in the pathogenesis of acute encephalopathy associated with human herpesvirus-6 (HHV-6 infection, we measured the levels of oxidative stress markers 8-hydroxy-2′-deoxyguanosine (8-OHdG and hexanoyl-lysine adduct (HEL, tau protein, and cytokines in cerebrospinal fluid (CSF obtained from patients with HHV-6-associated acute encephalopathy (HHV-6 encephalopathy (n=16 and complex febrile seizures associated with HHV-6 (HHV-6 complex FS (n=10. We also examined changes in CSF-8OHdG and CSF-HEL levels in patients with HHV-6 encephalopathy before and after treatment with edaravone, a free radical scavenger. CSF-8-OHdG levels in HHV-6 encephalopathy and HHV-6 complex FS were significantly higher than in control subjects. In contrast, CSF-HEL levels showed no significant difference between groups. The levels of total tau protein in HHV-6 encephalopathy were significantly higher than in control subjects. In six patients with HHV-6 infection (5 encephalopathy and 1 febrile seizure, the CSF-8-OHdG levels of five patients decreased after edaravone treatment. Our results suggest that oxidative DNA damage is involved in acute encephalopathy associated with HHV-6 infection.

Mutations or structural genomic alterations of the X-chromosomal gene ARHGEF9 have been described in male and female patients with intellectual disability. Hyperekplexia and epilepsy were observed to a variable degree, but incompletely described. Here, we expand the phenotypic spectrum of ARHGEF9 by describing a large Ethiopian-Jewish family with epilepsy and intellectual disability. The four affected male siblings, their unaffected parents and two unaffected female siblings were recruited and phenotyped. Parametric linkage analysis was performed using SNP microarrays. Variants from exome sequencing in two affected individuals were confirmed by Sanger sequencing. All affected male siblings had febrile seizures from age 2-3 years and intellectual disability. Three developed afebrile seizures between age 7-17 years. Three showed focal seizure semiology. None had hyperekplexia. A novel ARHGEF9 variant (c.967G>A, p.G323R, NM_015185.2) was hemizygous in all affected male siblings and heterozygous in the mother. This family reveals that the phenotypic spectrum of ARHGEF9 is broader than commonly assumed and includes febrile seizures and focal epilepsy with intellectual disability in the absence of hyperekplexia or other clinically distinguishing features. Our findings suggest that pathogenic variants in ARHGEF9 may be more common than previously assumed in patients with intellectual disability and mild epilepsy.

epidemiológico descriptivo y prospectivo se comparó la presencia de anticuerpos en niños que vivían en la zona costera de un país tropical donde el dengue es endémico, y en una zona del interior donde no lo es. Se usó inmunoadsorción enzimática para detectar IgG en el suero. Ninguno de los niños tenía antecedentes de dengue, enfermedad febril, tratamiento inmunosupresor o enfermedad subyacente. RESULTADOS: Durante el período transcurrido desde julio de 2003 hasta julio de 2003, se reunió a 103 niños de cada área. En la zona costera encontramos una seroprevalencia de IgG de 36,9%; en el interior, de 2,9%. CONCLUSIONES: Encontramos muchos casos de infección asintomática por el virus del dengue en niños costarricenses. Esto conlleva un riesgo elevado de fiebre hemorrágica del dengue o de síndrome de choque por dengue en estos niños en quienes la infección había pasado inadvertida. Es necesario tomar medidas preventivas en la región del litoral debido a la mayor prevalencia de la enfermedad en ella.

Full Text Available Objective: In view of the side effects of voiding cystourethrography (VCUG, identification of noninvasive markers predicting the presence of vesicoureteral reflux (VUR is important. This study was conducted to determine the predictive value of serum interleukin-8 (IL-8 in diagnosis of VUR in children with first febrile urinary tract infection (UTI. Materials and Methods: Eighty children with first febrile UTI were divided into two groups, with and without VUR, based on the results of VCUG. The sensitivity, specificity, positive and negative predictive value positive and negative likelihood ratio, and accuracy of IL-8 for prediction of VUR were investigated. Results: Of the 80 children with febrile UTI, 30 (37.5% had VUR. There was no significant difference between the children with and without VUR and also between low and high-grade VUR groups in terms of serum concentration of IL-8 (P>0.05. Based on ROC curve, the sensitivity, specificity, likelihood ratio positive, and accuracy of serum IL-8 was lower than those of erythrocyte sedimentation rate and C-reactive protein. Multivariate logistic regression analysis showed significant positive correlation only between erythrocyte sedimentation rate and VUR. Conclusions: This study showed no significant difference between the children with and without VUR in terms of the serum concentration of IL-8. Therefore, it seems that serum IL-8 is not a reliable marker for prediction of VUR.

Interferon gamma (IFN-γ plays an important role in fever induction and its expression increases with incubation at fever-range temperatures. Therefore, the genetic polymorphism of IFN-γ may modify the association of febrile infection with breast cancer risk. METHODOLOGY AND PRINCIPAL FINDINGS: Information on potential breast cancer risk factors, history of fever during the last 10 years, and blood specimens were collected from 839 incident breast cancer cases and 863 age-matched controls between October 2008 and June 2010 in Guangzhou, China. IFN-γ (rs2069705 was genotyped using a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry platform. Odds ratios (OR and 95% confidence intervals (CIs were calculated using multivariate logistic regression. We found that women who had experienced ≥1 fever per year had a decreased risk of breast cancer [ORs and 95% CI: 0.77 (0.61-0.99] compared to those with less than one fever a year. This association only occurred in women with CT/TT genotypes [0.54 (0.37-0.77] but not in those with the CC genotype [1.09 (0.77-1.55]. The association of IFN-γ rs2069705 with the risk of breast cancer was not significant among all participants, while the CT/TT genotypes were significantly related to an elevated risk of breast cancer [1.32 (1.03-1.70] among the women with <1 fever per year and to a reduced risk of breast cancer [0.63 (0.40-0.99] among women with ≥1 fever per year compared to the CC genotype. A marked interaction between fever frequencies and the IFN-γ genotypes was observed (P for multiplicative and additive interactions were 0.005 and 0.058, respectively. CONCLUSIONS: Our findings indicate a possible link between febrile acute infection and a decreased risk of breast cancer, and this association was modified by IFN-γ rs2069705.

Full Text Available La hiperglucemia es una manifestación frecuente en los pacientes hospitalizados dentro y fuera de la unidad de cuidados intensivos. La hiperglucemia se asocia, a su vez, con un aumento en la morbilidad, la mortalidad y la estancia hospitalaria. Los mecanismos causantes de estas complicaciones no están claros, pero se ha reconocido que múltiples procesos fisiológicos son afectados durante el aumento de la glucemia. Estudios prospectivos han demostrado un impacto positivo del control de los niveles de glucosa sobre varios parámetros clínicos y la mortalidad en diferentes grupos de pacientes críticos; sin embargo, las metas de control glucémico en los pacientes hospitalizados han sido cuestionadas. En consecuencia, muchos profesionales de la salud no tienen una aproximación bien formulada y objetiva para manejar la hiperglucemia en el hospital. En este artículo revisamos estudios observacionales y prospectivos relacionados a la hiperglucemia en pacientes hospitalizados, además de las opciones de manejo de la hiperglucemia y recomendaciones para la transición al control ambulatorio.

On May 21, 1997, numerous cases of febrile gastrointestinal illness were reported among the students and staff of two primary schools in northern Italy, all of whom had eaten at cafeterias served by the same caterer. We interviewed people who ate at the cafeterias about symptoms and foods consumed on May 20. There were no samples of foods left at the cafeterias, but we tested routine samples taken on May 20 by the caterer and environmental specimens at the catering plant. The hospitalized patients were tested for common enteropathogens and toxins. Of the 2189 persons interviewed (82 percent of those exposed), 1566 (72 percent) reported symptoms; of these, 292 (19 percent) were hospitalized. Among samples obtained from hospitalized patients, all but two of the stool specimens and all blood specimens were negative for common enteropathogens. Listeria monocytogenes was isolated from one blood specimen and from 123 of the 141 stool specimens. Consumption of a cold salad of corn and tuna was associated with the development of symptoms (relative risk, 6.19; 95 percent confidence interval, 4.81 to 7.98; Pcaterer's sample of the salad and from environmental specimens collected from the catering plant. All listeria isolates were serotype 4b and were found to be identical on DNA analysis. Experimental contamination of sterile samples of the implicated foods showed that L. monocytogenes grew on corn when kept for at least 10 hours at 25 degrees C. Food-borne infection with L. monocytogenes can cause febrile illness with gastroenteritis in immunocompetent persons.

The brain damage caused by repeated febrile seizure (FS) during developing age is harmful to the intellectual development of children. So how to decrease the related damage is a very important issue. The main purpose of the present study was to find out whether the non-specific opiate antagonist naloxone at low dose has the neuroprotective effect on seizure-induced brain damage. Warm water induced rat FS model was developed in this study. Forty-seven rats were randomly divided into two groups: normal control group (n = 10) and hyperthermic seizure groups (n = 37). The latter was further divided into FS control group (n = 13) and naloxone-treated group (n = 24). The dose of naloxone is different in two naloxone-treated groups (12/each group), in one group the dose was 1 mg/kg, in the other one 2 mg/kg. Seven febrile seizures were induced in each rat of hyperthermic seizure groups with the interval of 2 days. The rats were weighed and injected intraperitoneally with naloxone once the FS occurred in naloxone-treated group, while the rats of the other groups were injected with 0.9% sodium chloride. Latency, duration and grade of FS in different groups were observed and compared. HE-staining and the electron microscopy (EM) were used to detect the morphologic and ultrastructural changes of hippocampal neurons. In naloxone-treated group, the rats' FS duration and FS grade (5.02 +/- 0.63, 2.63 +/- 0.72) were significantly lower (t = 5.508, P seizure, it could lighten the brain damage resulted from repeated FS to some extent.

Full Text Available Summary: Long-term seroprevalence studies of dengue have provided a measure of the degree of endemicity and future trends in disease prevalence and severity. In this study, we describe the seroprevalence of dengue antibodies in febrile persons with suspected acute dengue in Barbados. It is a retrospective population-based study of all febrile persons with suspected dengue from 2006 to 2013. All of the cases had IgM and IgG antibodies in the blood sample drawn between days 3 and 5 of their illness. Among the 8296 cases that were tested for IgM antibodies, 3037 (36.6% had recent dengue infection. In the age groups 20 years, 23.3%, 39.6% and 35.5% had acute infection, respectively. Of the 7227 cases with documented IgG results, 5473 (75.7% were positive and had a past infection. In the age groups 20 years, 31.2%, 65.2% and 86.6%, respectively, had a past infection (IgG positive. During the first 5 years of life, 10–20% of febrile persons investigated for dengue had a positive IgM and a negative IgG titer, between 5 and 10% had a positive IgM and IgG titer, 5% had a positive IgG and a negative IgM titer, and between 45% and 65% had a negative IgM and a negative IgG titer. Throughout the study period, between 12% and 20% of febrile persons failed to show any evidence of current or previous dengue. In the age groups 20 years, 45.0%, 18.8% and 7.2%, respectively, had no evidence of recent or past dengue (both IgM and IgG negative. Between 37% and 59% of the febrile persons had serological evidence of past dengue in the absence of any current dengue. In conclusion, the pattern of IgG antibodies in this study was comparable to those in countries known to be hyperendemic for dengue. The age of infection is likely to shift to younger adults and children who are more likely to have severe dengue in the future. Keywords: Dengue, Seroprevalence, Febrile, Caribbean

We sought to characterize dengue virus (DENV) infections among febrile children enrolled in a pediatric cohort study who were clinically diagnosed with a non-dengue illness ("C cases"). DENV infections were detected and viral load quantitated by real-time reverse transcription-polymerase chain reaction in C cases presenting between January 2007 and January 2013. One hundred forty-one of 2892 C cases (4.88%) tested positive for DENV. Of all febrile cases in the study, DENV-positive C cases accounted for an estimated 52.0% of patients with DENV viremia at presentation. Compared with previously detected, symptomatic dengue cases, DENV-positive C cases were significantly less likely to develop long-lasting humoral immune responses to DENV, as measured in healthy annual serum samples (79.7% vs 47.8%; P dengue. These findings have important implications for DENV transmission modeling, immunology, and epidemiologic surveillance. © The Author 2017.

Infants with RSV infections have been found to have a clinically significant rate of urinary tract infections (UTIs). The American Academy of Pediatrics (AAP) published a revised Clinical Practice Guideline on UTIs in 2011, which includes major changes in diagnostic criteria for UTIs. Past research has been done using previous diagnostic criteria. The objective of the study is to assess the rate of UTIs in febrile infants with respiratory syncytial virus (RSV) infections according to the 2011 revised AAP Diagnostic Criteria and compare the rate of UTIs against the 1999 AAP Diagnostic Criteria. A retrospective comparative study of febrile infants (2-12 months) with RSV infections admitted to the Inpatient Pediatric unit of Lincoln Medical and Mental Center, Bronx, NY, from September through April 2006 to 2012. We applied the AAP's 1999 and 2011 diagnostic criteria for UTIs separately to assess the rates of UTIs. A total of 359 RSV-positive febrile patients who were investigated for UTIs were enrolled. Pyuria was found in 11.1% (40/359), positive urine culture 10 000 to 50 000 was found in 1.4% (5/359) and ≥50 000 in 4.7% (17/359). The rate of UTIs using AAP's 1999 criteria was 6.1% (22/359), and using the 2011 criteria the rate was 1.1% (4/359). The rate of UTIs was significantly different between the 2 groups (odds ratio [confidence interval] = 0.17 [0.05, 0.5], P = .001). The rate of UTIs in RSV-positive febrile infants is very low (1.1%) with the 2011 AAP diagnostic criteria. Previously described increased risk of UTIs may represent asymptomatic bacteriuria or contaminated specimens. © The Author(s) 2014.

Full Text Available Abstract Background Early diagnosis, as well as prompt and effective treatment of uncomplicated malaria, are essential components of the anti-malaria strategy in Madagascar to prevent severe malaria, reduce mortality and limit malaria transmission. The purpose of this study was to assess the performance of the malaria rapid diagnostic tests (RDTs used by community health workers (CHWs by comparing RDT results with two reference methods (microscopy and Polymerase Chain Reaction, PCR. Methods Eight CHWs in two districts, each with a different level of endemic malaria transmission, were trained to use RDTs in the management of febrile children under five years of age. RDTs were performed by CHWs in all febrile children who consulted for fever. In parallel, retrospective parasitological diagnoses were made by microscopy and PCR. The results of these different diagnostic methods were analysed to evaluate the diagnostic performance of the RDTs administered by the CHWs. The stability of the RDTs stored by CHWs was also evaluated. Results Among 190 febrile children with suspected malaria who visited CHWs between February 2009 and February 2010, 89.5% were found to be positive for malaria parasites by PCR, 51.6% were positive by microscopy and 55.8% were positive by RDT. The performance accuracy of the RDTs used by CHWs in terms of sensitivity, specificity, positive and negative predictive values was greater than 85%. Concordance between microscopy and RDT, estimated by the Kappa value was 0.83 (95% CI: 0.75-0.91. RDTs stored by CHWs for 24 months were capable of detecting Plasmodium falciparum in blood at a level of 200 parasites/μl. Conclusion Introduction of easy-to-use diagnostic tools, such as RDTs, at the community level appears to be an effective strategy for improving febrile patient management and for reducing excessive use of anti-malarial drugs.

Observation off continuous antibiotic prophylaxis is an option for vesicoureteral reflux. We evaluated the characteristics of patients observed off continuous antibiotic prophylaxis and risk factors for febrile urinary tract infection. We identified children 1 to 18 years old with primary vesicoureteral reflux between January 1, 2010 and December 31, 2010. We excluded patients with prior surgical correction from analysis. We recorded age, gender, race/ethnicity, primary language, insurance carrier, age at vesicoureteral reflux diagnosis, initial presentation and vesicoureteral reflux severity. We quantified bladder and bowel dysfunction with a validated questionnaire if toilet trained. We compared patients off vs on continuous antibiotic prophylaxis with the chi-square test for categorical variables and the Mann-Whitney U test for continuous variables. We used a univariate Cox proportional hazards model to assess predictors of febrile urinary tract infection during observation off continuous antibiotic prophylaxis. Of 529 eligible patients 224 were observed off continuous antibiotic prophylaxis. Patients off continuous antibiotic prophylaxis tended to be older (p urinary tract infection (p = 0.05), to have nondilating vesicoureteral reflux on most recent cystogram (p urinary tract infection developed in 19 (8.5%). Risk factors associated with febrile urinary tract infection included initial presentation of multiple febrile urinary tract infections (p = 0.03), older age at diagnosis (p = 0.03) and older age starting observation off continuous antibiotic prophylaxis (p = 0.0003). Criteria to select patients with vesicoureteral reflux for observation off continuous antibiotic prophylaxis remain poorly defined in the literature. Observation will fail in a subset of patients with vesicoureteral reflux. Physician biases regarding patient selection for observation off continuous antibiotic prophylaxis should be considered when interpreting studies that evaluate treatment

AL-Majali, R.M.

2004-01-01

Objectives: To study the relationship between White Blood Cell (WBC), Absolute Neutrophil Count (ANC) in febrile children 1-18 months of age as predictor of bacterial infection, so as to improve our predictability of bacterial infections in emergency room to decrease unnecessary admissions and antibiotic use. Methods: Retrospective review was performed on febrile patients 1-18 months of age that were admitted to hospital between August 2002 and March 2003 on the presumptive diagnosis of fever without focus, Complete septic work up was done for all patients according to local hospital protocol including Complete blood count (CBC), blood culture, urine culture, Chest X-Ray (CXR) and lumbar puncture, Patients who had history of antibiotics use within 48 hours of admission were excluded from the study, History, physical examination, laboratory and radiology data were reviewed. Data about the age, sex, temperature, presence or absence of focal bacterial infection, WBC, ANC, CXR report and body fluid culture results were collected and analyzed. Results: Thirty-four patients were reviewed in this study, Eight patients (23.5%) had bacterial infection: classified as group (2 patchy pneumonia, 3 Urinary tract infection (UTI), 2 meningitis, 1 Occult bacteremia (OB) and 26 patients (76.5%) had no evidence of bacterial infection, classified as group 2, No significant difference was found between the two groups in respect to age, sex, temperature and WBC P>0.05, while there was a significant difference between the two groups in respect to the ANC P = 0.02, also ANC had better sensitivity (78%) and specificity (89%) than WBC (sensitivity 77%, specificity 62%). Conclusion: ANC is a good predictive test for determining bacterial infection in young febrile children without focus, However there is need for other more reliable rapid cost effective measures in dealing with young febrile children at emergency department.

Febrile children were randomly assigned to the intervention (clinical decision model; n = 219 or the control group (usual care; n = 220. The clinical decision model included clinical symptoms, vital signs, and C-reactive protein and provided high/low-risks for "pneumonia" and "other SBI". Nurses were guided by the intervention to initiate additional tests for high-risk children. The clinical decision model was evaluated by 1 area-under-the-receiver-operating-characteristic-curve (AUC to indicate discriminative ability and 2 feasibility, to measure nurses' compliance to model recommendations. Primary patient outcome was defined as correct SBI diagnoses. Secondary process outcomes were defined as length of stay; diagnostic tests; antibiotic treatment; hospital admission; revisits and medical costs.The decision model had good discriminative ability for both pneumonia (n = 33; AUC 0.83 (95% CI 0.75-0.90 and other SBI (n = 22; AUC 0.81 (95% CI 0.72-0.90. Compliance to model recommendations was high (86%. No differences in correct SBI determination were observed. Application of the clinical decision model resulted in less full-blood-counts (14% vs. 22%, p-value < 0.05 and more urine-dipstick testing (71% vs. 61%, p-value < 0.05.In contrast to our expectations no substantial impact on patient outcome was perceived. The clinical decision model preserved, however, good discriminatory ability to detect SBI, achieved good compliance among nurses and resulted in a more standardized diagnostic approach towards febrile children, with less full blood-counts and more rightfully urine-dipstick testing.Nederlands Trial Register NTR2381.

These diseases are often under-ascertained and underreported because of their unspecific clinical signs and symptoms, insufficient awareness by physicians and public health officers and limited diagnostic capabilities, especially in low-resource countries. Therefore, the presence of Brucella spp., Coxiella burnetii and Burkholderia pseudomallei was investigated in Malagasy patients exhibiting febrile illness. In addition, we analyzed zebu cattle and their ticks as potential reservoirs for Brucella and C. burnetii, respectively. Specific quantitative real-time PCR assays (qPCRs) were performed on 1020 blood samples drawn from febrile patients. In total, 15 samples (1.5%) were Brucella-positive, mainly originating from patients without travel history, while DNA from C. burnetii and Bu. pseudomallei was not detected. Anti-C. burnetii antibodies were found in four out of 201 zebu serum samples (2%), whereas anti-Brucella antibodies could not be detected. Brucella DNA was detected in a single zebu sample. Three out of 330 ticks analyzed (1%) were positively tested for C. burnetii DNA but with high Ct values in the qPCR assay. Our data suggest that zebus as well as Amblyomma and Boophilus ticks have to be considered as a natural reservoir or vector for C. burnetii, but the risk of cattle-to-human transmission is low. Since bovine brucellosis does not seem to contribute to human infections in Madagascar, other transmission routes have to be assumed. Copyright © 2017 The Authors. Published by Elsevier B.V.

Purpose To evaluate the practical applications of the diagnosis algorithms recommended by the American Academy of Pediatrics urinary tract infection (UTI) guideline. Methods We retrospectively reviewed the medical records of febrile UTI patients aged between 2 and 24 months. The patients were divided into 3 groups: group I (patients with positive urine culture and urinalysis findings), group II (those with positive urine culture but negative urinalysis findings), and group III (those with negative urine culture but positive urinalysis findings). Clinical, laboratory, and imaging results were analyzed and compared between the groups. Results A total of 300 children were enrolled. The serum C-reactive protein level was lower in children in group II than in those in groups I and III (P<0.05). Children in group I showed a higher frequency of hydronephrosis than those in groups II and III (P<0.05). However, the frequencies of acute pyelonephritis (APN), vesicoureteral reflux (VUR), renal scar, and UTI recurrence were not different between the groups. In group I, recurrence of UTI and presence of APN were associated with the incidence of VUR (recurrence vs. no recurrence: 40% vs.11.4%; APN vs. no APN: 23.3% vs. 9.2%; P<0.05). The incidence of VUR and APN was not related to the presence of hydronephrosis. Conclusion UTI in febrile children cannot be ruled out solely on the basis of positive urinalysis or urine culture findings. Recurrence of UTI and presence of APN may be reasonable indicators of the presence of VUR. PMID:26512260

The source of sepsis in febrile patients can be a difficult diagnostic problem. Gallium-67 has been utilized as a diagnostic tool in the evaluation of these patients. A retrospective review was done of 47 patients who presented with pyrexia of unknown origin (27 patients), postoperative fever (11 patients), septicaemia (4 patients) and miscellaneous sepsis (5 patients). Whole body imaging with Gallium-67 gave an overall sensitivity and specificity of 86 and 77%, respectively, which compares favourably with previous studies. The sensitivity and specificity was similar in all patient subgroups. Gallium-67 allowed for more effective and directed use of organ-specific imaging modalities, such as computed tomography, ultrasound and guided intervention, in localizing and defining the source of sepsis. Where more than one possible source of fever was present, Gallium-67 scanning correctly identified the activity of the different foci. Gallium-67 scanning should be used early in the evaluation of patients presenting with fever of uncertain origin. 9 refs., 5 tabs., 2 figs

Full Text Available Kawasaki disease (KD is an acute pediatric vasculitis of infants and young children with unknown etiology and no specific laboratory-based test to identify. A specific molecular diagnostic test is urgently needed to support the clinical decision of proper medical intervention, preventing subsequent complications of coronary artery aneurysms. We used a simple and low-cost colorimetric sensor array to address the lack of a specific diagnostic test to differentiate KD from febrile control (FC patients with similar rash/fever illnesses.Demographic and clinical data were prospectively collected for subjects with KD and FCs under standard protocol. After screening using a genetic algorithm, eleven compounds including metalloporphyrins, pH indicators, redox indicators and solvatochromic dye categories, were selected from our chromatic compound library (n = 190 to construct a colorimetric sensor array for diagnosing KD. Quantitative color difference analysis led to a decision-tree-based KD diagnostic algorithm.This KD sensing array allowed the identification of 94% of KD subjects (receiver operating characteristic [ROC] area under the curve [AUC] 0.981 in the training set (33 KD, 33 FC and 94% of KD subjects (ROC AUC: 0.873 in the testing set (16 KD, 17 FC. Color difference maps reconstructed from the digital images of the sensing compounds demonstrated distinctive patterns differentiating KD from FC patients.The colorimetric sensor array, composed of common used chemical compounds, is an easily accessible, low-cost method to realize the discrimination of subjects with KD from other febrile illness.

Cases of undiagnosed severe febrile rhabdomyolysis in refugees coming from West Africa, mainly from Nigeria, has been observed since May 2014. The aim of this study was to describe this phenomenon. This was a multicentre retrospective observational study of cases of febrile rhabdomyolysis reported from May 2014 to December 2016 in 12 Italian centres. A total of 48 cases were observed, mainly in young males. The mean time interval between the day of departure from Libya and symptom onset was 26.2 days. An average 8.3 further days elapsed before medical care was sought. All patients were hospitalized with fever and very intense muscle aches. Creatine phosphokinase, aspartate aminotransferase, and lactate dehydrogenase values were abnormal in all cases. The rhabdomyolysis was ascribed to an infective agent in 16 (33.3%) cases. In the remaining cases, the aetiology was undefined. Four out of seven patients tested had sickle cell trait. No alcohol abuse or drug intake was reported, apart from a single reported case of khat ingestion. The long incubation period does not support a mechanical cause of rhabdomyolysis. Furthermore, viral infections such as those caused by coxsackievirus are rarely associated with such a severe clinical presentation. It is hypothesized that other predisposing conditions like genetic factors, unknown infections, or unreported non-conventional remedies may be involved. Targeted surveillance of rhabdomyolysis cases is warranted. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

BACKGROUND: ASCO and EORTC guidelines recommend granulocyte colony-stimulating factor (G-CSF) primary prophylaxis for cancer patients with a ≥20% overall risk of febrile neutropenia (FN), and to support delivery of dose-dense regimens. CHOP-like regimens (with rituximab [R]) are the current...... standard of care for the management of aggressive non-Hodgkin lymphoma (NHL), but they are often associated with significant myelosuppression. Neutropenic events, particularly febrile neutropenia (FN), can be life-threatening and may lead to dose delays or reductions that compromise the efficacy......-CSF primary prophylaxis. Across all cycles, 29% of R-CHOP-21 patients had an unplanned hospitalization, with neutropenia/FN being the main reason. Subsequently, 67% of patients achieved a relative dose intensity (RDI) of ≥90% of their planned treatment (with respect to cyclophosphamide, doxorubicin...

Exposure to febrile-range hyperthermia potentiates Wnt signalling and epithelial-mesenchymal transition gene expression in lung epithelium.

As environmental and body temperatures vary, lung epithelial cells experience temperatures significantly different from normal core temperature. Our previous studies in human lung epithelium showed that: (i) heat shock accelerates wound healing and activates profibrotic gene expression through heat shock factor-1 (HSF1); (ii) HSF1 is activated at febrile temperatures (38-41 °C) and (iii) hypothermia (32 °C) activates and hyperthermia (39.5 °C) reduces expression of a subset of miRNAs that target protein kinase-Cα (PKCα) and enhance proliferation. We analysed the effect of hypo- and hyperthermia exposure on Wnt signalling by exposing human small airway epithelial cells (SAECs) and HEK293T cells to 32, 37 or 39.5 °C for 24 h, then analysing Wnt-3a-induced epithelial-mesenchymal transition (EMT) gene expression by qRT-PCR and TOPFlash reporter plasmid activity. Effects of miRNA mimics and inhibitors and the HSF1 inhibitor, KNK437, were evaluated. Exposure to 39.5 °C for 24 h increased subsequent Wnt-3a-induced EMT gene expression in SAECs and Wnt-3a-induced TOPFlash activity in HEK293T cells. Increased Wnt responsiveness was associated with HSF1 activation and blocked by KNK437. Overexpressing temperature-responsive miRNA mimics reduced Wnt responsiveness in 39.5 °C-exposed HEK293T cells, but inhibitors of the same miRNAs failed to restore Wnt responsiveness in 32 °C-exposed HEK293T cells. Wnt responsiveness, including expression of genes associated with EMT, increases after exposure to febrile-range temperature through an HSF1-dependent mechanism that is independent of previously identified temperature-dependent miRNAs. This process may be relevant to febrile fibrosing lung diseases, including the fibroproliferative phase of acute respiratory distress syndrome (ARDS) and exacerbations of idiopathic pulmonary fibrosis (IPF).

No evidence can be found in the medical literature about the efficacy of alternating acetaminophen and ibuprofen treatment in children with refractory fever. Our objective was to assess the effect of alternating acetaminophen and ibuprofen therapy on distress and refractory fever compared with acetaminophen or ibuprofen as monotherapy in febrile children. A total of 474 febrile children with axillary temperature ≥38.5 °C and fever history ≤3 days in a tertiary hospital were randomly assigned to receive either (1) alternating acetaminophen and ibuprofen (acetaminophen 10 mg/kg per dose with shortest interval of 4 h and ibuprofen 10 mg/kg per dose with shortest interval of 6 h and the shortest interval between acetaminophen and ibuprofen ≥2 h; n = 158), (2) acetaminophen monotherapy (10 mg/kg per dose with shortest interval of 4 h; n = 158), or (3) ibuprofen monotherapy (10 mg/kg per dose with shortest interval of 6 h; n = 158). The mean Non-Communicating Children's Pain Checklist (NCCPC) score was measured every 4 h, and axillary temperatures were measured every 2 h. In total, 471 children were included in an intention-to-treat analysis. No significant clinical or statistical difference was found in mean NCCPC score or temperature during the 24-h treatment period in all febrile children across the three groups. Although the proportion of children with refractory fever for 4 h and 6 h was significantly lower in the alternating group than in the monotherapy groups (4 h: 11.54% vs. 26.58% vs. 21.66%, respectively [p = 0.003]; 6 h: 3.85% vs. 10.13% vs. 17.83%, respectively [p ibuprofen can reduce the proportion of children with refractory fever, but if one cycle of alternating therapy cannot reduce febrile distress as defined by NCCPC score, two or more cycles of alternating therapy may have minimal to no clinical efficacy in some cases. The trial was registered with the Chinese Clinical Trial Registry as ChiCTR-TRC-13003440 and the WHO

Despite the drastic change in the evaluation of the febrile young child due to the decreased incidence of serious bacterial infections (SBI) effected by Haemophilus influenza type B and pneumococcal vaccine, there remains a small role for blood work in the evaluation of these patients. Bacterial markers including white blood cell (WBC) count, absolute neutrophil count (ANC) and C-reactive protein (CRP) have been studied and are widely used as predictors of SBI in febrile children. It has been suggested that CRP values should be interpreted cautiously when fever has been present predictors of SBI in relation to duration of fever. Patients who presented to a pediatric emergency department between the ages of 1 and 36 months, with fever > or =39 degrees C and no source of infection had a complete blood count (CBC) blood culture, and CRP level drawn. A urinalysis and/or urine culture was obtained when age and gender appropriate. A chest X-ray was performed at the discretion of the treating physician. The study subjects were enrolled prospectively and then divided into two groups based on duration of fever of 12 h, and compared. One hundred and twenty-eight patients were originally enrolled. Nine patients were excluded. Seventeen patients (14%) had SBI. One patient (urinary tract infections. Forty-five patients presented with fever 12 h. Area under the curve (AUC) for WBC, ANC and CRP was significantly larger in patients with SBI presenting with fever >12 h (0.85, 0.83, 0.92 respectively) compared to patients with SBI who presented with fever for 12 h as shown by the AUC. CRP performed better than WBC and ANC in both scenarios.

OBJECTIVE AND METHODS: This study was undertaken to find the role of fluorine-18-fluorodeoxyglucose (F18-FDG) in the diagnostic work-up of febrile Acquired Immune Deficiency Syndrome (AIDS) patients. Forty-seven (42 male and 5 female; mean age = 40.3 years) febrile patients with AIDS underwent imaging with F18-FDG by Dual Head Coincidence Imaging (DHCI). Findings were correlated with other imaging modalities.RESULTS: Our data show good sensitivity for scanning with F18-FDG by DHCI in determining the extent of Castleman's disease, lymphoma, Kaposi's sarcoma (KS), adenocarcinoma, and germ cell carcinoma. Various opportunistic infections also manifest with increased F18-FDG uptake.CONCLUSION: Total-body imaging can be done with F18-FDG with better resolution and a shorter procedure time compared to imaging with Gallium-67 (Ga-67). Furthermore, F18-FDG is more sensitive than Ga-67 for evaluating extent of involvement in various pathologies affecting AIDS patients. The new technology of DHCI is a good alternative for hospitals with no dedicated positron emission tomography (PET) scanner.

Full Text Available Bacteremia following febrile neutropenia is a serious complication in children with malignancies. Preventive measures are currently targeted at antimicrobial prophylaxis, amelioration of drug-induced neutropenia, and nosocomial spread of pathogens, with little attention to community-acquired infections. A retrospective study was conducted at a pediatric oncology center during a 3-year period to identify probable cases of food-borne infections with bacteremia. Twenty-one bacteremic illnesses affecting 15 children receiving chemotherapy or hematopoietic stem cell transplantation were reviewed. Three (14% episodes were highly suspected of a food-borne origin: a 17-year-old boy with osteosarcoma contracted Sphingomonas paucimobilis septicemia after consuming nasi lemak bought from a street hawker; a 2-year-old boy with acute lymphoblastic leukemia developed Chryseobacterium meningosepticum septicemia after a sushi dinner; a 2-year-old girl was diagnosed with acute lymphoblastic leukemia and Lactobacillus bacteremia suspected to be of probiotic origin. All of them were neutropenic at the time of the infections and the bacteremias were cleared with antibiotic treatment. Food-borne sepsis may be an important, but readily preventable, cause of bloodstream infections in pediatric oncology patients, especially in tropical countries with an abundance of culinary outlets.

To validate a prognostic score predicting major complications in patients with solid tumors and seemingly stable episodes of febrile neutropenia (FN). The definition of clinical stability implies the absence of organ dysfunction, abnormalities in vital signs, and major infections. We developed the Clinical Index of Stable Febrile Neutropenia (CISNE), with six explanatory variables associated with serious complications: Eastern Cooperative Oncology Group performance status ≥ 2 (2 points), chronic obstructive pulmonary disease (1 point), chronic cardiovascular disease (1 point), mucositis of grade ≥ 2 (National Cancer Institute Common Toxicity Criteria; 1 point), monocytes < 200 per μL (1 point), and stress-induced hyperglycemia (2 points). We integrated these factors into a score ranging from 0 to 8, which classifies patients into three prognostic classes: low (0 points), intermediate (1 to 2 points), and high risk (≥ 3 points). We present a multicenter validation of CISNE. We prospectively recruited 1,133 patients with seemingly stable FN from 25 hospitals. Complication rates in the training and validation subsets, respectively, were 1.1% and 1.1% in low-, 6.1% and 6.2% in intermediate-, and 32.5% and 36% in high-risk patients; mortality rates within each class were 0% in low-, 1.6% and 0% in intermediate-, and 4.3% and 3.1% in high-risk patients. Areas under the receiver operating characteristic curves in the validation subset were 0.652 (95% CI, 0.598 to 0.703) for Talcott, 0.721 (95% CI, 0.669 to 0.768) for Multinational Association for Supportive Care in Cancer (MASCC), and 0.868 (95% CI, 0.827 to 0.903) for CISNE (P = .002 for comparison between CISNE and MASCC). CISNE is a valid model for accurately classifying patients with cancer with seemingly stable FN episodes. © 2015 by American Society of Clinical Oncology.

To find out the frequency of co-existence of malaria and dengue fever in patients presenting with acute febrile illness. Methods: The descriptive cross-sectional study was conducted at the Military Hospital Rawalpindi from June to November 2012. A total of 500 patients with complaint of acute febrile illness were selected after applying the inclusion and exclusion criteria. Preliminary data was collected on a pretested proforma. Blood samples of patients were tested for dengue serology and malaria parasite. Results were entered in respective proforma. Co-existence was considered present when a patient had both dengue serology and malaria parasite slide positive. SPSS 20 was used for data analysis. Result: Of the total, 349 (69.8%) were males and 151 (30.2%) females. Dengue serology was positive in 16 (3.2%); 81(16.2%) had malaria parasite slide positive; 403 (80.4%) had none of the two findings. Co-existence of both dengue and malaria was nil among the whole sample. In males, 67 (13.4%) had malaria, while 11 (2.2%) had dengue. In females, 14 (2.8%) had malaria, while 5 (1%) suffered from dengue fever. Conclusion: Co-existence of dengue and malaria was zero per cent in 500 patients visiting Military Hospital Rawalpindi. More studies shall be conducted to find out whether the reason of having zero per cent co-existence is that dengue or/and malaria epidemic did not occur in 2012 or whether there are some other factors involved.

There is a lack of severity assessment tools to identify adults presenting with febrile urinary tract infection (FUTI) at risk for complicated outcome and guide admission policy. We aimed to validate the Prediction Rule for Admission policy in Complicated urinary Tract InfeCtion LEiden (PRACTICE), a modified form of the pneumonia severity index, and to subsequentially assess its use in clinical practice. A prospective observational multicenter study for model validation (2004-2009), followed by a multicenter controlled clinical trial with stepped wedge cluster-randomization for impact assessment (2010-2014), with a follow up of 3 months. Paricipants were 1157 consecutive patients with a presumptive diagnosis of acute febrile UTI (787 in validation cohort and 370 in the randomized trial), enrolled at emergency departments of 7 hospitals and 35 primary care centers in the Netherlands. The clinical prediction rule contained 12 predictors of complicated course. In the randomized trial the PRACTICE included guidance on hospitalization for high risk (>100 points) and home discharge for low risk patients (urinary tract infection, futher improvement is necessary to reduce the occurrence of secondary hospital admissions.

Full Text Available Background: Febrile neutropenia is a common complication in patients undergoing chemotherapy or hematopoietic Stem Cell Transplantation (HSCT. Flexible fiberoptic bronchoscopy has been used to aid in the diagnosis of pulmonary diseases. However, there is no consensus regarding the benefit of the exam in establishing diagnosis and in changing the treatment of lung disease in this context. Previous retrospective studies, quite heterogeneous and with non-HIV immunocompromised patients, showed that the yield of fiberoptic bronchoscopy in establishing etiology ranges from 13% to 81%, and in changing therapy, from 5% to 51%. Aim: To evaluate the efficiency of Fiberoptic bronchoscopy and the procedure-related risk for neutropenic patients with hematologic malignancy. Methods: This retrospective cross-sectional study analyzed the medical records of patients with hematologic malignancy with febrile neutropenia who had undergone diagnostic fiberoptic bronchoscopy between January 2011 and December 2012 at the Hospital de Clínicas de Porto Alegre. Results: A total of 45 patients were included: 18 (36% tested positive for bronchoalveolar lavage, with change in therapeutic management occurring for 95% of them. The procedure-related risk was 2.2%, with one patient showing desaturation immediately after the procedure. Conclusion:  Despite the limited number of patients, our findings indicate that fiberoptic bronchoscopy in neutropenic patients is safe, and the results are similar to those previously reported.

In two major clinical trials, voriconazole and caspofungin were recommended as alternatives to liposomal amphotericin B for empirical use in febrile neutropenia. This study investigated the health economic impact of using voriconazole vs. caspofungin in patients with febrile neutropenia. A decision analytic model was developed to measure downstream consequences of empirical antifungal therapy. Clinical outcomes measured were success, breakthrough infection, persistent base-line infection, persistent fever, premature discontinuation and death. Treatment transition probabilities and patterns were directly derived from data in two relevant randomised controlled trials. Resource use was estimated using an expert clinical panel. Cost inputs were obtained from latest Australian sources. The analysis adopted the perspective of the Australian hospital system. The use of caspofungin led to a lower expected mean cost per patient than voriconazole (AU$40,558 vs. AU$41,356), with a net cost saving of AU$798 (1.9%) per patient. Results were most sensitive to the duration of therapy and the alternative therapy used post-discontinuation. In uncertainty analysis, the cost associated with caspofungin is less than that with voriconazole in 65.5% of cases. This is the first economic evaluation of voriconazole vs. caspofungin for empirical therapy. Caspofungin appears to have a higher probability of having cost-savings than voriconazole for empirical therapy. The difference between the two medications does not seem to be statistically significant however. © 2011 Blackwell Verlag GmbH.

Full Text Available Dengue is an emerging infectious disease of global significance. Suspected dengue, especially in children in Nicaragua's heavily-urbanized capital of Managua, has been well documented, but unsuspected dengue among children and adults with undifferentitated fever has not.To prospectively study dengue in semi-urban and rural western Nicaragua, we obtained epidemiologic and clinical data as well as acute and convalescent sera (2 to 4 weeks after onset of illness from a convenience sample (enrollment Monday to Saturday daytime to early evening of consecutively enrolled patients (n = 740 aged ≥ 1 years presenting with acute febrile illness. We tested paired sera for dengue IgG and IgM and serotyped dengue virus using reverse transcriptase-PCR. Among 740 febrile patients enrolled, 90% had paired sera. We found 470 (63.5% were seropositive for dengue at enrollment. The dengue seroprevalance increased with age and reached >90% in people over the age of 20 years. We identified acute dengue (serotypes 1 and 2 in 38 (5.1% patients. Only 8.1% (3/37 of confirmed cases were suspected clinically.Dengue is an important and largely unrecognized cause of fever in rural western Nicaragua. Since Zika virus is transmitted by the same vector and has been associated with severe congenital infections, the population we studied is at particular risk for being devastated by the Zika epidemic that has now reached Central America.

Kidney cancer represents 3 % of the tumors in adults. In the United States, the 45% is diagnosed in early stages. Its natural history is characterized for being absolutely unpredictable and probably related to hormonal, immunologic and unknown factors. There are patients in advanced stage with prolonged or low average survival and even with metastasis declination. These particularities along with the lack of prospective random studies make difficult to establish which is the roll of the adjuvant radiotherapy, being considered not standard since 1997. [Spanish] El cancer de rinion representa el 3% de los tumores en adultos. En Estados Unidos el 45% se diagnostica en estadios tempranos. Su historia natural se caracteriza por ser absolutamente impredecible, probablemente relacionado a factores hormonales, inmunologicos y desconocidos; hay pacientes con enfermedad avanzada con prolongada o corta supervivencia media e incluso con regresion de metastasis. Estas particularidades, juntamente con la falta de estudios prospectivos aleatorios dificultan establecer cual es el rol de la radioterapia adyuvante, considerandose no estandar desde 1997.

The plasma HGH concentrations were assayed in total 138 cases by the radioimmunoassay. The groups of control, typhoid fever, epidemic hemorrhagic fever, tuberculous meningitis and other febrile diseases were studied, also were the groups of hyperthyroidism, acromegaly and hypopituitarism. Insulin stimulation test was performed in control, typhoid fever and hypopituitarism. In the control group, the plasma HGH concentration in fasting (early morning) was 2.06±1.183 mμg/ml and its upper limit was 4.5 mμg/ml. No sexual difference was observed. By the insulin stimulation, plasma HGH concentration had rised to the peak level of 24.1±15.71 mμg/ml, 60 min. after the intravenous insulin injection, then decreased to the normal level progressively. In typhoid fever, fasting HGH concentrations in febrile state and in defeverence were 2.5±1.35 mμg/ml and 2.2±3.32 mμg/ml respectively, showing no significant difference with the control group. However, the levels of individual cases ranged widely, compared with the control group. The response to the insulin stimulation test was similar to the control group. In epidemic hemorrhagic fever. the HGH concentrations in oliguric phase, in diuretic phase and in convalescence were 4.2±3.71 mμg/ml, 2.2±l.30 mμg/ml and 3.4±3.01 mμg/ml respectively. No significant differences were observe when compared to the control, but they showed wide range of plasma HGH levels. In tuberculous meningitis, the fasting HGH concentration was 2.9±51.42 mμg/ml. In the other febrile diseases, the value was 2.5±2.23 mμg/ml. In 4 cases of hypopituitarism, the fasting HGH concentration was 2.3±0.42 mμg/ml and ranged normally. However, the response to the insulin stimulation test was not observed. Very high plasma HGH concentrations were observed in acromegalic patients.

Full Text Available In 2010, the World Health Organization (WHO published updated guidelines emphasizing and expanding recommendations for a parasitological confirmation of malaria before treating with antimalarials. This study aimed to assess differences in historic (2007-2008 (cohort 1 and recent (2011-2012 (cohort 2 hospital cohorts in the diagnosis and treatment of febrile illness in a low malaria prevalence area of northern Tanzania.We analyzed data from two prospective cohort studies that enrolled febrile adolescents and adults aged ≥13 years. All patients received quality-controlled aerobic blood cultures and malaria smears. We compared patients' discharge diagnoses, treatments, and outcomes to assess changes in the treatment of malaria and bacterial infections.In total, 595 febrile inpatients were enrolled from two referral hospitals in Moshi, Tanzania. Laboratory-confirmed malaria was detected in 13 (3.2% of 402 patients in cohort 1 and 1 (0.5% of 193 patients in cohort 2 (p = 0.041.

Previous research has identified clinical predictors for urinary tract infection (UTI) to guide urine screening in febrile children or =38 degrees C) infants who were pediatric emergency departments from October through March 1999-2001 were eligible. Clinical appearance was evaluated using the Yale Observation Scale. UTI was defined as growth of a known bacterial pathogen from a catheterized specimen at a level of (1) > or =50000 cfu/mL or (2) > or =10000 cfu/mL in association with a positive dipstick test or urinalysis. We used bivariate tests and multiple logistic regression to identify demographic and clinical factors that were associated with the likelihood of UTI. A total of 1025 (67%) of 1513 eligible patients were enrolled; 9.0% of enrolled infants received a diagnosis of UTI. Uncircumcised male infants had a higher rate of UTI (21.3%) compared with female (5.0%) and circumcised male (2.3%) infants. Infants with maximum recorded temperature of > or =39 degrees C had a higher rate of UTI (16.3%) than other infants (7.2%). After multivariable adjustment, UTI was associated with being uncircumcised (odds ratio: 10.4; bias-corrected 95% confidence interval: 4.7-31.4) and maximum temperature (odds ratio: 2.4 per degrees C; 95% confidence interval: 1.5-3.6). Factors that were reported previously to be associated with risk for UTI in infants and toddlers, such as white race and ill appearance, were not significantly associated with risk for UTI in this cohort of young infants. Being uncircumcised and height of fever were associated with UTI in febrile infants who were < or =60 days of age. Uncircumcised male infants were at particularly high risk and may warrant a different approach to screening and management.

Since its publication more than 15 years ago, the MASCC score has been internationally validated any number of times and recommended by most clinical practice guidelines for the management of febrile neutropenia (FN) around the world. We have used an empirical data-supported simulated scenario to demonstrate that, despite everything, the MASCC score is impractical as a basis for decision-making. A detailed analysis of reasons supporting the clinical irrelevance of this model is performed. First, seven of its eight variables are "innocent bystanders" that contribute little to selecting low-risk candidates for ambulatory management. Secondly, the training series was hardly representative of outpatients with solid tumors and low-risk FN. Finally, the simultaneous inclusion of key variables both in the model and in the outcome explains its successful validation in various series of patients. Alternative methods of prognostic classification, such as the Clinical Index of Stable Febrile Neutropenia, have been specifically validated for patients with solid tumors and should replace the MASCC model in situations of clinical uncertainty.

Intermittent diazepam prophylaxis in febrile convulsions. Pros and cons.

Science.gov (United States)

Knudsen, F U

1991-01-01

Major cohort studies document that the long-term prognosis for most children with febrile convulsions (FC) is excellent. The 2 main treatment alternatives so far have been long-term prophylaxis with phenobarbital or valproate or no prophylaxis at all. Phenobarbital at times of fever is ineffective and obsolete. Consensus has emerged that long-term prophylaxis with antiepileptic drugs is rarely justified in FC considering the side effects and the favourable prognosis. No treatment at all does not appear quite satisfactory either, as FC have a high recurrence rate, disrupt family life and may have emotional consequences for the family. Moreover, all FC children face a risk, although admittedly low, of subsequent long-lasting potentially central nervous system (CNS)-damaging seizures. However, 2 further options exist: treatment with rapid-acting benzodiazepines solely at times of greatest risk, i.e., at high fever or at renewed seizures. Several clinical trials have confirmed that intermittent diazepam prophylaxis by way of a few doses of the drug per year provides effective seizure control and reduces the recurrence rate by one half or two thirds. The treatment is feasible and cheap, well tolerated by the child and well accepted by the parents. Compliance problems are common and only partly abatable. Trivial side effects are frequent. Transient respiratory apnoea does occur, but 15 years' experience substantiates that serious side effects are remarkably rare. Acute anticonvulsant treatment with rectal diazepam in solution given by the parents to stop ongoing seizures and to prevent immediate recurrences is an attractive alternative. It is feasible, is probably effective and minimizes the use of drugs, but compliance problems are common and protracted seizures are not always controlled. The subsequent management should include a risk profile approach considering a combination of risk factors for new FC rather than a single factor. By means of a risk index, based on

Full Text Available Abstract Background Households in malaria endemic countries experience considerable costs in accessing formal health facilities because of childhood malaria. The Ministry of Health in Malawi has defined certain villages as hard-to-reach on the basis of either their distance from health facilities or inaccessibility. Some of these villages have been assigned a community health worker, responsible for referring febrile children to a health facility. Health facility utilization and household costs of attending a health facility were compared between individuals living near the district hospital and those in hard-to-reach villages. Methods Two cross-sectional household surveys were conducted in the Chikhwawa district of Malawi; one during each of the wet and dry seasons. Half the participating villages were located near the hospital, the others were in areas defined as hard-to-reach. Data were collected on attendance to formal health facilities and economic costs incurred due to recent childhood febrile illness. Results Those living in hard-to-reach villages were less likely to attend a formal health facility compared to those living near the hospital (Dry season: OR 0.35, 95%CI0.18-0.67; Wet season: OR 0.46, 95%CI0.27-0.80. Analyses including community health workers (CHW as a source of formal health-care decreased the strength of this relationship, and suggested that consulting a CHW may reduce attendance at health facilities, even if indicated. Although those in hard-to-reach villages were still less likely to attend in both the dry (OR 0.53, 95%CI 0.25-1.11 and wet (OR 0.60, 95%CI 0.37-0.98 seasons. Household costs for those who attended a health facility were greater for those in HTR villages (Dry: USD5.24; Wet: USD5.60 than for those living near the district hospital (Dry: USD3.45; Wet: USD4.46. Conclusion Those living in hard-to-reach areas were less likely to attend a health facility for a childhood febrile event and experienced greater

Leptospirosis is often mistaken for other acute febrile illnesses because of its nonspecific presentation. Bacteriologic, serologic, and molecular methods have several limitations for early diagnosis: technical complexity, low availability, low sensitivity in early disease, or high cost. This study aimed to validate a case definition, based on simple clinical and laboratory tests, that is intended for bedside diagnosis of leptospirosis among hospitalized patients. Adult patients, admitted to two reference hospitals in Recife, Brazil, with a febrile illness of less than 21 days and with a clinical suspicion of leptospirosis, were included to test a case definition comprising ten clinical and laboratory criteria. Leptospirosis was confirmed or excluded by a composite reference standard (microscopic agglutination test, ELISA, and blood culture). Test properties were determined for each cutoff number of the criteria from the case definition. Ninety seven patients were included; 75 had confirmed leptospirosis and 22 did not. Mean number of criteria from the case definition that were fulfilled was 7.8±1.2 for confirmed leptospirosis and 5.9±1.5 for non-leptospirosis patients (pcase definition, for a cutoff of at least 7 criteria, reached average sensitivity and specificity, but with a high positive predictive value. Its simplicity and low cost make it useful for rapid bedside leptospirosis diagnosis in Brazilian hospitalized patients with acute severe febrile disease.

Objective: To identify the genetic cause in a large family with febrile seizures (FS) and temporal lobe epilepsy (TLE) and subsequently search for additional mutations in a cohort of 107 families with FS, with or without epilepsy. Methods: The cohort consisted of 1 large family with FS and TLE, 64 smaller French families recruited through a national French campaign, and 43 Italian families. Molecular analyses consisted of whole-exome sequencing and mutational screening. Results: Exome sequencing revealed a p.Glu402fs*3 mutation in the γ2 subunit of the GABAA receptor gene (GABRG2) in the large family with FS and TLE. Three additional nonsense and frameshift GABRG2 mutations (p.Arg136*, p.Val462fs*33, and p.Pro59fs*12), 1 missense mutation (p.Met199Val), and 1 exonic deletion were subsequently identified in 5 families of the follow-up cohort. Conclusions: We report GABRG2 mutations in 5.6% (6/108) of families with FS, with or without associated epilepsy. This study provides evidence that GABRG2 mutations are linked to the FS phenotype, rather than epilepsy, and that loss-of-function of GABAA receptor γ2 subunit is the probable underlying pathogenic mechanism.

Vujevic M, Benzon B, Markic J. New prediction model for diagnosis of bacterial infection in febrile infants younger than 90 days. Turk J Pediatr 2017; 59: 261-268. Due to non-specific clinical presentation in febrile infants, extensive laboratory testing is often carried out to distinguish simple viral disease from serious bacterial infection (SBI). Objective of this study was to compare efficacy of different biomarkers in early diagnosis of SBI in infants Pediatrics, University Hospital Centre Split with suspicion of having SBI were included in this study. Retrospective cohort analysis of data acquired from medical records was performed. Out of 181 enrolled patients, SBI was confirmed in 70. Most common diagnosis was urinary tract infection (68.6%), followed by pneumonia (12.9%), sepsis (11.4%), gastroenterocolitis (5.7%) and meningitis (1.4%). Male gender was shown to be a risk factor for SBI in this population (p=0.008). White blood cell count (WBC), absolute neutrophil count (ANC) and C-reactive protein (CRP) were confirmed as the independent predictors of SBI, with CRP as the best one. Two prediction models built by combining biomarkers and clinical variables were selected as optimal with sensitivities of 74.3% and 75.7%, and specificities of 88.3% and 86%. Evidently, CRP is a more superior biomarker in diagnostics of SBI comparing to WBC and ANC. Prediction models were shown to be better in predicting SBI than independent biomarkers. Although both showed high sensitivity and specificity, their true strength should be determined using validation cohort.

To assess the sensitivity and negative predictive value (NPV) of screening renal and bladder ultrasound (RBUS) after initial febrile urinary tract infection (UTI) among patients with clinically significant vesicoureteral reflux (VUR). A retrospective review was performed of all children UTI between 2004 and 2011. The sensitivity and NPV of initial RBUS was calculated among patients who were found to have high-grade (IV-V) VUR. Additionally, initial RBUS among patients with evidence of photopenia on dimercaptosuccinic acid (DMSA) scan or who underwent surgical intervention were reviewed. One hundred forty-four patients with febrile UTI were identified; available RBUS, voiding cystourethrogram (VCUG), and DMSA results for each kidney were reviewed. One hundred fifty-eight kidneys had evidence of VUR on VCUG, and initial RBUS demonstrated abnormality in 25 (sensitivity 0.17). Forty-five kidneys had high-grade VUR and RBUS revealed abnormality in 16 (sensitivity 0.36). One hundred seventy-eight kidneys had no evidence of abnormality on initial RBUS, and 136 (76%) were found to have VUR (NPV 0.24), of which 31 had high-grade VUR (NPV 0.83). Seven kidneys had scarring on DMSA and initial RBUS was normal in 4 (57%). Twelve of 19 patients (63%) who eventually underwent surgical intervention had a normal initial RBUS. RBUS has poor sensitivity and NPV for detecting high-grade VUR in patients UTI. A significant number of patients who were diagnosed with high-grade VUR, renal scarring, or underwent surgical correction of VUR had a negative screening RBUS. Copyright © 2013 Elsevier Inc.

Full Text Available Recently, major progress has been made in controlling malaria in Africa. However, in Gabon, little information is available on the role of malaria in childhood febrile syndromes, the use and efficacy of preventive measures, and Plasmodium species distribution. Here, we characterized malaria in febrile children in Franceville, Gabon through a cross-sectional study at the pediatric unit of the Franceville Regional Hospital. We registered 940 febrile children. Their general condition was markedly altered in 11.7% of cases (n = 89/760; among them 19 (21.4% had a severely altered condition. Malaria was the second most frequent etiology (22.0%; n = 162/738, after respiratory tract infections (37.3%; n = 275/738. Children with malaria (63 ± 39 months were older than children without malaria (40 ± 37 months (p = 0.0013. Hemoglobin, red blood cell, white blood cell, and platelet values were lower in children with malaria than in those without malaria (p < 0.0001. Anemia was the most common feature of severe malaria (70.6%; n = 12/17, followed by neurological involvement (23.5%; n = 4/17. The prevalence of malaria was significantly higher in children older than 60 months than in younger children (40% vs. 15.5%; p < 0.0001. Plasmodium falciparum accounted for 97.5% of cases (158/162, followed by Plasmodium malariae (2.5%; n = 4/162. Bed net use was high (74.4%; n = 697/936 and contributed to malaria prevention (p = 0.001. Good basic knowledge of malaria also had a preventive effect (p < 0.0001. The prevalence of malaria in children in Franceville did not decrease significantly from 2009 to 2012, remaining at about 20%, highlighting that preventive measures should be reinforced.

Anticonvulsive effect of paeoniflorin on experimental febrile seizures in immature rats: possible application for febrile seizures in children.

Directory of Open Access Journals (Sweden)

Hitomi Hino

Full Text Available Febrile seizures (FS is the most common convulsive disorder in children, but there have been no clinical and experimental studies of the possible treatment of FS with herbal medicines, which are widely used in Asian countries. Paeoniflorin (PF is a major bioactive component of Radix Paeoniae alba, and PF-containing herbal medicines have been used for neuromuscular, neuropsychiatric, and neurodegenerative disorders. In this study, we analyzed the anticonvulsive effect of PF and Keishikashakuyaku-to (KS; a PF-containing herbal medicine for hyperthermia-induced seizures in immature rats as a model of human FS. When immature (P5 male rats were administered PF or KS for 10 days, hyperthermia-induced seizures were significantly suppressed compared to control rats. In cultured hippocampal neurons, PF suppressed glutamate-induced elevation of intracellular Ca(2+ ([Ca(2+](i, glutamate receptor-mediated membrane depolarization, and glutamate-induced neuronal death. In addition, PF partially suppressed the elevation in [Ca(2+](i induced by activation of the metabotropic glutamate receptor 5 (mGluR5, but not that mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolpropionic acid (AMPA or N-methyl-D-aspartate (NMDA receptors. However, PF did not affect production or release of γ-aminobutyric acid (GABA in hippocampal neurons. These results suggest that PF or PF-containing herbal medicines exert anticonvulsive effects at least in part by preventing mGluR5-dependent [Ca(2+](i elevations. Thus, it could be a possible candidate for the treatment of FS in children.

Conclusion: As NHL present with nonspecific symptoms, these tumours may not be detected in early stages and hence may not be treated appropriately. These patients have weakened immunity and hence are prone to infection and sepsis which can be a major cause of mortality. This autopsy study experience has shown that NHL can masquerade as acute febrile illness which if not detected early and treated adequately can turn fatal.

Full Text Available En este artículo se usa el marco conceptual de Carlson et al. (2003 para discutir los resultados de un estudio de caso, el cual describe la forma como un estudiante razona covariacionalmente al enfrentarse a situaciones de variación asociadas a funciones cuadráticas. El estudio se ideó para desarrollar una línea convergente de indagación (Yin, 2009, la cual se centró en las descripciones que el estudiante realizaba a medida que abordaba las situaciones diseñadas para el estudio; dichas descripciones fueron trianguladas con las producciones escritas y los elementos teóricos. Desde las acciones que el estudiante evidenció, se pudo observar que el proceso de razonamiento covariacional no es un proceso lineal pero sí recursivo. Así mismo, este estudio de caso pone en evidencia el hecho de que existen estudiantes que pueden aproximarse a una interpretación variacional de las concavidades de una gráfica, sin que ello exija un estudio previo del cálculo diferencial. Del estudio se desprenden algunas implicaciones tanto para el marco conceptual abordado en este estudio como para el diseño de situaciones orientadas al aula de clase.

To assess the prevalence of malaria helminth co-infections and their contribution for aneamia in febrile patients attending Azzezo health center, Gondar, Northwest Ethiopia. A cross section study was conducted among febrile patients attending Azezo health center from February-March 30, 2011. Convenient sampling technique was used to select 384 individuals. Both capillary blood and stool were collected. Giemsa stained thick and thin blood film were prepared for identification of Plasmodium species and stool sample was examined by direct wet mount and formalin-ether concentration technique for detection of intestinal helminthes parasites. Haemoglobin concentration was determined using a portable haemoglobin spectrophotometer, Hemocue Hb 201 analyzer. Out of 384 febrile patients examined for malaria parasites, 44 (11.5%) individuals were positive for malaria parasites, of which Plasmodium vivax accounted for 75.0% (33), Plasmodium falciparum for 20.5% (9) infectious, whereas two person (4.5%) had mixed species infection. Prevalence of malaria was higher in males (28) when compared with prevalence in females (16). More than half (207, 53.9%) of study participants had one or more infection. Prevalence was slightly higher in females (109, 52.7%) than in males (98, 47.3%). About helminths, Ascaris lumbricoides was the predominant isolate (62.1%) followed by hookworms (18.4%). Only 22 participants were co-infected with malaria parasite and helminths and co-infection with Ascaris lumbricoides was predominant (45.0%). The prevalence of anemia was 10.9% and co-infection with Plasmodium and helminth parasites was significantly associated with (Pparasitic infections is very crucial to improve health of the affected communities in economically developing countries.

Background Urinary tract infection (UTI) is an infection that affects part of the urinary tract. Ultrasound is a noninvasive test that can demonstrate the size and shape of kidneys, presence of dilatation of the ureters, and the existence of anatomic abnormalities. The aim of the study is to estimate the value of ultrasound in detecting urinary tract anomalies after first attack of UTI. Methods This study was conducted at the Nephrology Clinic, New Children's Hospital, Faculty of Medicine, Cairo University, from August 2012 to March 2013, and included 30 children who presented with first attack of acute febrile UTI. All patients were subjected to urine analysis, urine culture and sensitivity, serum creatinine, complete blood count, and imaging in the form of renal ultrasound, voiding cysto-urethrography, and renal scan. Results All the patients had fever with a mean of 38.96°C ± 0.44°C and the mean duration of illness was 6.23 ± 5.64 days. Nineteen patients (63.3%) had an ultrasound abnormality. The commonest abnormalities were kidney stones (15.8%). Only 2 patients who had abnormal ultrasound had also vesicoureteric reflux on cystourethrography. Sensitivity of ultrasound was 66.7%, specificity was 37.5%, positive predictive value was 21.1%, negative predictive value was 81.8%, and total accuracy was 43.33%. Conclusion We concluded that ultrasound alone was not of much value in diagnosing and putting a plan of first attack of febrile UTI. It is recommended that combined investigations are the best way to confirm diagnosis of urinary tract anomalies. © The Author(s) 2015.

Alarming signs and symptoms in febrile children in primary care: an observational cohort study in The Netherlands.

Directory of Open Access Journals (Sweden)

Gijs Elshout

Full Text Available CONTEXT: Febrile children in primary care have a low risk for serious infection. Although several alarming signs and symptoms are proposed to have predictive value for serious infections, most are based on research in secondary care. The frequency of alarming signs/symptoms has not been established in primary care; however, in this setting differences in occurrence may influence their predictive value for serious infections. OBJECTIVE: To determine the frequency of alarming signs/symptoms in febrile children in primary care. DESIGN: Observational cohort study. Clinical information was registered in a semi-structured way and manually recoded. SETTING: General practitioners' out-of-hours service. SUBJECTS: Face-to-face patient contacts concerning children (aged ≤16 years with fever were eligible for inclusion. MAIN OUTCOME MEASURES: Frequency of 18 alarming signs and symptoms as reported in the literature. RESULTS: A total of 10,476 patient contacts were included. The frequency of alarming signs/symptoms ranged from n = 1 (ABC instability; 40°C as reported by the parents; 12.9% to 8,647 contacts (parental concern; 82.5%. CONCLUSION: Although the prevalence of specific alarming signs/symptoms is low in primary care, ≥50% of children have one or more alarming signs/symptoms. There is a need to determine the predictive value of alarming signs/symptoms not only for serious infections in primary care, but as well for increased risk of a complicated course of the illness.

This is a follow up study of a multicenter randomised placebo-controlled trial in seven centres in five West European countries. The RCT assessed the effect of infant formula supplemented with a mixture of prebiotics (with neutral short-chain and long-chain oligosaccharides and pectin-derived acidic oligosaccharides) during infancy in term-born children (n=1130). In the follow-up study 672 children (60% of the study population) participated: 232 (56%) from the prebiotics group (PG), 243 (58%) from the control group (CG), and 197 (66%) from the non-randomised breast-fed group (BG). The primary outcome was the occurrence of febrile episodes at three to five years of age prospectively documented by the parents: in the PG 1.17 (interquartile range 0.50-2.08) episodes per year versus 1.20 (0.52-2.57) in the CG; and 1.48 (0.65-2.60) in the BG. This specific prebiotics mixture given during infancy in healthy non-atopic subjects does not decrease febrile episodes and therefore seems not to prevent infection between their third and fifth birthday.

The clinical effects of concomitant use of granulocyte-colony stimulating factor (G-CSF) on empiric antibiotic therapy in febrile neutropenic patients were evaluated in a randomized fashion. Two hundred and fourteen neutropenic febrile episodes (neutrophil counts flomoxef sodium and tobramycin with or without G-CSF. The resolution of fever at day 4 (excellent response) or at day 7 (good response) was deemed effective. Among 157 evaluable episodes, the observed excellent responses were 31 (38.8%) and the good responses were 20 (25.0%) in the G-CSF group; those in the control group were 26 (33.8%) and 25 (32.5%), respectively. The overall efficacy rate was 63.8% (51/80) in the G-CSF group and 66.2% (51/77) in the control group (not significant). The initial neutrophil count was 0.186 +/- 0.249 x 10(9)/l in the G-CSF group and 0.235 +/- 0.290 x 10(9)/l in the control group, and rose to 2.889 +/- 4.198 x 10(9)/l and 0.522 +/- 0.844 x 10(9)/l, respectively, at day 7. These results indicate that G-CSF does not affect the rate of response to empiric antibiotic therapy in febrile neutropenic patients, although a significant effect of G-CSF was observed on neutrophil recovery.
