Propiedades nutricionales, tecno-funcionales y aplicación en alimentos del frijol mungo (Vigna radiata)

El frijol mungo (Vigna radiata) es una leguminosa ampliamente producida y consumida en países asiáticos. Esta leguminosa gradualmente ha ido tomando importancia dentro de la gastronomía de occidente, tanto por su valor nutricional como por sus propiedades biológicas y tecnológicas. Dentro de sus propiedades nutricionales se destaca el contenido de proteínas, carbohidratos, fibra y compuestos fenólicos. Las semillas de frijol mungo con un adecuado tratamiento, ya sea de germinación, fermentación o aislamiento, ha demostrado tener propiedades biológicas como la antioxidante, antidiabética, antihipertensiva, antiinflamatoria y anticancerígena. Por otro lado, dentro de las propiedades tecnológicas podemos destacar las propiedades emulsificante, espumante, gelificante, absorción de aceite y de agua. Todas estas propiedades mencionadas hacen que el frijol mungo sea un ingrediente de interés para la industria de alimentos, por lo cual, se hace necesario realizar una revisión de los estudios recientes acerca de los atributos nutricionales, tecno-funcionales y aplicaciones en el área de alimentos.

The mung bean (Vigna radiata) is a legume widely produced and consumed in Asian countries. This legume has gradually gained importance in western gastronomy for its nutritional value and biological and technological properties. Among its nutritional properties, the content of protein, carbohydrates, fibre, and phenolic compounds stands out. With proper treatment, whether it is germination, fermentation or isolation, mung beans have been shown to have biological properties such as antioxidant, antidiabetic, antihypertensive, anti-inflammatory, and anticancer. However, we can highlight the properties of emulsifying, foaming, geling, oil, and water absorption within the technological properties. All these properties make the mung bean an ingredient of interest for the food industry, for which it is necessary to review recent studies on the nutritional, techno-functional attributes and applications in the food area.

Uso ambulatorio de cefalosporinas en una población colombiana: estudio de prescripción-indicación / Outpatient cephalosporin use in a Colombian population: prescription-indication study

INTRODUCCIÓN: El uso indebido de cefalosporinas puede provocar resistencia de las bacterias. OBJETIVO: Determinar el perfil de prescripción e indicación de cefalosporinas en un grupo de pacientes afiliados al Sistema de Salud de Colombia. MÉTODOS: Estudio transversal. A partir de una base de datos poblacional se obtuvo una muestra aleatoria de pacientes atendidos en consulta ambulatoria para identificar las indicaciones de cefalosporinas en registros clínicos. Se evaluaron variables farmacológicas relacionadas con formulación no indicada según guías de práctica clínica. RESULTADOS: En 381 pacientes, con edad media 41,2 ± 15,4 años, el 61,4% (n = 234) eran mujeres. Cefalexina fue la más utilizada (n=318; 83,5%), con duración media del tratamiento de 7,3 ± 3,2 días, seguida de cefradina (n = 43, 11,3%) y ceftriaxona (n = 20, 5,2%). Se prescribieron para infecciones de piel y tejidos blandos (n = 177; 46,4%, de las cuales 47,5% eran purulentas), del tracto urinario (n = 70; 18,4%), de vías respiratorias superiores (n = 57; 15,0%), e infecciones de transmisión sexual (n = 21; 5,5%). Estaban indicadas en 169 pacientes (44,4%), pero sólo 103 (60,9%) tenían prescripciones que cumplían las recomendaciones de dosificación. CONCLUSIONES: Más de la mitad de pacientes prescritos con cefalosporinas en un contexto ambulatorio tenían prescripciones consideradas no indicadas, en particular por su uso en infecciones de piel y tejidos blandos purulentas.

BACKGROUND: Misuse of cephalosporins can lead to bacterial resistance. Aim: To determine the prescription profile and indication of cephalosporins in the patients affiliated to the Colombian Health System. METHODS: Cross-sectional study. From a population database, a random sample of patients treated in an outpatient consultation was obtained, to identify the indications of the prescribed cephalosporins in their clinical record. Pharmacological variables, and those related to non-indicated formulations were evaluated according to the clinical practice guidelines. RESULTS: In 381 patients, the mean age was 41.2 ± 15.4 years, and 61.4% (n = 234) were women. Cefalexin was the most widely used (n=318; 83.5%), with a mean duration of treatment of 7.3 ± 3.2 days; followed by cefradine (n = 43; 11.3%), and ceftriaxone (n = 20; 5.2%). The most common uses were for skin and soft tissue infections (n = 177; 46.4% of which 47.5% were purulent), urinary tract infections (n = 70; 18.4%), upper respiratory airway infections (n = 57; 15.0%) and sexually transmitted diseases (n = 21; 5.5%). The use was considered indicated in 169 patients (44.4%), but only 103 (60.9%) had prescriptions that met the dosage recommendations from the clinical practice guidelines. CONCLUSIONS: More than half of the patients prescribed with cephalosporins in the outpatient setting had prescriptions considered not indicated, particularly for their use in purulent skin and soft tissue infections.

Blastocystis spp. y su asociación con otros parásitos intestinales en niños de edad preescolar, estado Sucre, Venezuela / Blastocystis spp. and their association to other intestinal parasites in preschool children from Sucre State, Venezuela

Introducción: Blastocystis spp. es uno de los parásitos intestinales más comunes en el ser humano y su patogenicidad sigue siendo controvertida. Objetivo: Determinar la prevalencia de Blastocystis spp. y su asociación con otros parásitos intestinales a niños en edad preescolar. Métodos: Se procesaron 90 muestras fecales provenientes de niños en edad preescolar. Las técnicas copro-parasitológicas usadas fueron: examen directo con solución salina (0,85 por ciento) y lugol. Se usó la prueba chi cuadrado para demostrar la independencia entre las variables: parasitosis, sexo y edad. Se determinó el índice de afinidad de Fager para establecer las asociaciones entre los principales enteroparásitos identificados. Resultados: Se encontraron 68 niños parasitados, con 75,6 por ciento de prevalencia. No hubo diferencias significativas con respecto a la edad y el sexo (p> 0,05). Los parásitos más comunes fueron: Blastocystis spp. (45,6 por ciento), Endolimax nana (30,9 por ciento), Entamoeba coli (26,5 por ciento), y como único helminto, Enterobius vermicularis (1,5 por ciento). El 42,6 por ciento estuvo monoparasitado y 57,4 por ciento biparasitados. Los índices de afinidad (IAB) y pruebas de "t" efectuadas, señalaron asociación significativa entre Blastocystis spp. y los protozoarios E. nana y E. coli. Conclusiones: Se determina una elevada prevalencia de Blastocystis spp. y especies comensales intestinales, todas indicadoras de contaminación fecal, en que probablemente factores ambientales y socioculturales promueven su transmisión. Este tema debe continuarse y profundizarse por la connotación que ha adquirido este parásito en los debates científicos actuales, tanto en el ámbito nacional como internacional(AU)

Introduction: Blastocystis spp. are among the most common intestinal parasites affecting humans. Their pathogenicity continues to be a topic of debate. Objective: Determine the prevalence of Blastocystis spp. and their association to other intestinal parasites in preschool children. Methods: Analysis was performed of 90 stool samples from preschool children. The coproparasitological techniques used were direct examination with 0.85 percent saline solution and lugol. The chi-square test was used to show the independence between the variables parasitic infection, sex and age. Fager's affinity index was determined to establish associations between the main enteroparasites identified. Results: The study found 68 children infected with parasites, for a 75.6 percent prevalence. There were no significant differences with respect to age and sex (p> 0.05). The most common parasites were Blastocystis spp. (45.6 percent), Endolimax nana (30.9 percent) and Entamoeba coli (26.5 percent). The only helminth found was Enterobius vermicularis (1.5 percent). 42.6 percent of the children were infected with one parasite and 57.4 percent with two. The affinity index (IAB) and t tests performed revealed a significant association between Blastocystis spp. and the protozoa E. nana and E. coli. Conclusions: High prevalence was determined of Blastocystis spp. and intestinal protozoan species, all of which were indicative of fecal contamination. Environmental and sociocultural factors are likely to facilitate their transmission. This topic should continue to be addressed and examined due to the relevance of this parasite in current scientific debate, both nationally and internationally(AU)

Perspectivas investigativas en torno a las parejas sin hijos y su relación con el concepto de "familia": Un estado del arte / Investigative perspectives on couples without children and their relationship with the concept of "family": A state of the art

Resumen El objetivo del trabajo que se informa fue mostrar cuáles son las transformaciones que las investigaciones manifiestan sobre la familia e identificar si las parejas sin hijos son consideradas como una tipología emergente de configuración familiar. A partir de una investigación documental al modo de estado del arte, se recolectaron 35 artículos entre 1992 y 2017, que se analizaron desde una perspectiva hermenéutica a partir de los núcleos temáticos "definición y transformación del concepto de 'familia'" y "perspectivas investigativas en torno a la relación entre parejas sin hijos y familia". La mayoría concuerda con que la consanguinidad y la procreación ya no son criterios indispensables para conformar una familia, y así, las parejas sin hijos se constituyen como una nueva tipología familiar que se caracteriza por modos más equitativos, consensuales y democráticos de tomar decisiones; todo esto, bajo el contexto social de una profunda transformación de los roles de género desde el siglo XX.

Abstract The objective of the work reported was to show the transformations the research shows about the family and to identify if couples without children are considered as an emerging typology of family configuration. The importance of the relationship between the categories of family and a couple without children is that this is a time when a significant reduction in the birth rate can be seen worldwide. Furthermore, households made up of couples who state that they do not want to have children also represent a striking increase. On the other hand, this phenomenon has led to the emergence of research categories such as DINK, Childfree and NoMo families, which converge in the increase of couples without children and of women who do not wish to have children. From a documentary research under the modality of the state of the art, 35 articles were collected for this study between 1992 and 2017, which were analyzed from a hermeneutic perspective from the thematic nuclei "definition and transformation of the concept of 'family'" and "Research perspectives on the relationship between childless couples and family". The search required the following categories in Spanish and English: "significado de familia/meaning of family", "definición de familia/definition of family", "concepto de familia/family concept", "parejas sin hijos/couple without children/childfree/NoMo", "nuevas tipologías familiares/new family typologies", "familia DINK/DINK family" y "familia moderna/modern family". The databases taken into account for the study were Scopus, SciELO, Dialnet Plus, Psicodoc, EBSCO, DOAJ, Redalyc and Google Academic. Most research agrees that consanguinity and procreation are no longer essential criteria for forming a family, and thus, couples without children are constituted as a new family typology characterized by more equitable, consensual and democratic ways of making decisions. The main reason for this change is the new place that women have conquered in society after decades of struggle for their rights, favoring a questioning of the patriarchal system and the hegemonic model of the family called the nuclear family. The discussions about gender imaginaries that began with greater force in the 20th century, give a place to women in working life that, over time, has favored a questioning about the relationship between motherhood and being a woman. Research presents different criteria to define the family, which shows that this is a time when there is not one model but several family models. For its part, this diversity has been expressed not only in the dimension of social representations but also in the legal sphere; This is expressed this way, since several investigations in the field of law show transformations in Latin American constitutions by ways of understanding the family in a more plural way and based on fundamental rights. Finally, the collection of research shows that the study on the category of couples without children is incipient, that is, it corresponds to a phenomenon that, despite enjoying statistical evidence, can be considered emergent in culture insofar as its relevance corresponds to the last decades. Most studies that deal directly or indirectly with the category of childless couple, consider this form of bond as a form of family and explain how at this time this definition is mainly determined by affective criteria, values built between the members, and relational dynamics; leaving in the background the criteria of consanguinity or kinship from the nuclear model.

Clinical features of 47 patients infected with COVID-19 admitted to a Regional Reference Center

ABSTRACT Background: During the first pandemic wave, Covid-19 reached Latin America cities. Aim: To report clinical features and outcomes of a group of patients with Covid-19 admitted to a Chilean regional reference Center. Material and Methods: Cases were identified by a compatible clinical picture and a positive PCR or serological test. Clinical features of patients were retrieved from medical records. Results: Forty-seven adult patients (45 diagnosed by PCR, 2 by serology) were admitted between epidemiological weeks 13 to 33, corresponding to 4.4% of total regional cases. Hospitalization occurred at a median of 10 days after onset of symptoms. Fifty one percent of patients had 60 years or more. Hypertension, obesity and diabetes mellitus were present in 57, 45 and 32 % of cases, respectively. Nineteen percent of patients had no comorbid condition nor were elderly. Two cases were women in their second trimester of pregnancy. Positive IgM or IgM/IgG results obtained by rapid serological testing, had limited sensitivity during the first week (67%). Seventeen patients (36.2%) were transferred to an intensive care unit (ICU) due to respiratory failure. Chest imaging demonstrated a classical COVID-19 pattern in 87%. By univariate analysis, admission to ICU was significantly associated with tachypnea and higher CALL (comorbidity, age, lymphocyte count and lactate dehydrogenase) score. Four patients died (rendering a hospital mortality of 8.5%) and length of stay was ≥ 14 days in 46.8% of patients. By univariate analysis, mortality was associated with immunosuppression and ICU admission. Conclusions: In our regional Center, patients admitted with COVID-19 had usual risk factors and had a prolonged stay. Hospital mortality was associated with immunosuppression and ICU admission.

Antecedentes: Durante la primera ola pandémica, COVID-19 llegó a las ciudades de América Latina. Objetivos: Informar las características clínicas y los resultados asociados a COVID-19 en un grupo de pacientes ingresados en un Centro de referencia regional en el sur de Chile. Material y Métodos: Los casos fueron identificados por un cuadro clínico compatible asociado a RT-PCR positiva o prueba serológica. La información clínica de los pacientes se obtuvo de sus fichas. Resultados: Entre las semanas epidemiológicas 13 y 33 ingresaron 47 pacientes adultos (45 diagnosticados por PCR, 2 por serología), lo que representa el 4,4% del total de casos regionales. La hospitalización se produjo con una mediana de 10 días después del inicio de los síntomas. El 51% de los pacientes tenía 60 años o más. La hipertensión arterial (57,4%), la obesidad (44,7%) y la diabetes mellitus 2 (31,9%) fueron prevalentes, pero el 19% no presentaba comorbilidades ni era un adulto mayor. Dos casos ocurrieron en mujeres embarazadas en el segundo trimestre. Los resultados positivos de IgM o IgM / IgG obtenidos mediante pruebas serológicas rápidas tuvieron una sensibilidad limitada durante la primera semana (66,7%). Diecisiete pacientes (36,2%, grupo crítico) fueron trasladados a UCI por insuficiencia respiratoria. Las imágenes de tórax demostraron un patrón COVID-19 clásico en el 87% de los casos. Por análisis univariado, el ingreso en UCI se asoció significativamente con taquipnea y puntuaciones CALL (comorbidity, age, lymphocyte count and lactate dehydrogenase) elevadas. Cuatro pacientes fallecieron (mortalidad hospitalaria 8,5%) y la estadía hospitalaria fue ≥ 14 días en el 47% de los pacientes. Por análisis univariado la mortalidad se asoció a inmunodepresión y al ingreso a UCI. Conclusiones: En nuestro Centro regional, COVID-19 se asoció a factores de riesgo conocidos y tuvo una estadía prolongada. La mortalidad hospitalaria se asoció con inmunosupresión o ingreso a UCI.

Penicillin desensitization in allergic pregnant women with syphilis. Report of two cases / Desensibilización a penicilina en mujeres embarazadas alérgicas. Informe de dos casos

ABSTRACT Syphilis during pregnancy has a high risk of congenital transmission with disastrous fetal consequences. Penicillin (PNC) is the only effective antimicrobial for the treatment of pregnant women with syphilis. Chilean guidelines do not consider desensitization to PNC in these women. We report two cases of pregnant women aged 32 and 23 years, with immediate allergy to PNC and syphilis who were safely and successfully desensitized using a four-hour intravenous protocol in the critical care unit and who subsequently received benzathine G PNC. An electronic survey was conducted among approximately 100 Clinical Pharmacists (CP) in the country. Of these, 16 answered and 13 reported having experience in drug desensitization, in at least five cases with PNC and none reported deaths or cardiorespiratory arrest. Desensitization to PNC can be carried out safely and in Chile, this alternative should be incorporated to the management of pregnant women with syphilis and immediate allergy to PNC, instead of using erythromycin.

La sífilis durante el embarazo tiene un alto riesgo de transmisión congénita con consecuencias desastrosas para el feto. La penicilina (PNC) es el único compuesto efectivo para el tratamiento de sífilis en una mujer embarazada.. En Chile, ante alergias de tipo inmediata, no se considera la desensibilización a la PNC en mujeres embarazadas por norma ministerial. Se comunican dos casos de mujeres embarazadas con alergia tipo inmediata y sífilis durante la gestación que fueron desensibilizadas a este compuesto con un protocolo endovenoso de 4 horas en la unidad de pacientes críticos, sin observar complicaciones, recibiendo posteriormente PNC G Benzatina. Se efectuó una encuesta electrónica a farmacéuticos clínicos del país que incluyó más de 100 profesionales. De ellos, 16 contestaron y 13 declararon poseer experiencia en desensibilización de fármacos, en al menos cinco casos con PNC y ninguno reportó muertes o paro cardiorrespiratorio. La desensibilización a PNC puede ser efectuada en forma segura en embarazadas con alergia de tipo inmediata a PNC que cursan con sífilis. En Chile se debería incorporar esta alternativa en el manejo de mujeres embarazadas con sífilis y alergia inmediata a PNC en lugar de solo considerar por norma el uso de eritromicina.

Responsabilidade civil e suas consequências no exercício da Dermatologia / Civil responsibility and its consequences for the Dermatology practice

Introdução: No Brasil estima-se que um grande número de processos de responsabilidade civil contra profissionais médicos esteja em andamento nos tribunais. Objetivos: Analisar os acórdãos dos Tribunais de Justiça das regiões Sudeste e Sul do Brasil que envolvam o dermatologista e sua responsabilidade civil. Métodos: Definição de protocolo de pesquisa no site dos Tribunais de Justiça dos estados da Região Sudeste e da Região Sul do Brasil. Resultados: Foram identificados 47 acórdãos nesses estados. As principais causas que motivaram a responsabilidade civil do dermatologista estão ligadas aos procedimentos estéticos, à insatisfação do paciente em relação às condutas terapêuticas e ao erro diagnóstico. As indenizações solicitadas nos processos judiciais contra o dermatologista foram, em sua maioria, por danos morais. A perícia médica foi solicitada pelos juízes na maioria dos processos, e, em 87,2% das conclusões das perícias, não foi observado o nexo causal. As decisões judiciais favoráveis ao dermatologista ocorreram em 82,9% dos casos. Não foi possível conhecer na íntegra o processo judicial, mas apenas o relatório final. Conclusão: Podemos concluir que fatores como a boa formação do dermatologista, sua atenção à relação médico/paciente e o cuidado ao preencher o prontuário e os documentos necessários à prática médica foram essenciais para uma perícia médica adequada e, em consequência, fundamentais para que as sentenças judiciais fossem favoráveis ao dermatologista na maioria dos casos focalizados neste estudo.

Introduction: It is estimated that in Brazil, a large number of civil responsibility lawsuits against the medical professional are in place at the courts. Objectives: To analyze the rulings of Justice Tribunals of the Southeast and South regions of Brazil, involving dermatologists and their civil responsibility. Methods: Definition of a research protocol on the site of the Justice Tribunals of the Southeast and South regions of Brazil. Results: Forty-seven rulings were identified in the States of the Southeast and South regions. The main causes motivating civil responsibility of the dermatologist are linked to aesthetic procedures, to patient dissatisfaction regarding therapies chosen and to diagnostic error. Compensations sought in lawsuits against dermatologists were mostly for moral damage. Medical evaluation was requested by the judges in most lawsuits and in 87.2% the reports did not observe a causal relationship. Court decision were in favor of the dermatologists in 82.9% of the cases. It was not possible to see the full lawsuit, only the final report. Conclusion: We can conclude that factors such as adequate training of the dermatologist, their attention to doctor-patient relationship and when filling out patient's records and documents necessary to medical practice were essential to an adequate medical evaluation, crucial to court decisions favoring dermatologists in most cases included in this study.

Hemangioma de crecimiento mínimo o detenido con lipoatrofia: presentación de un caso clínico / Hemangioma with minimal or arrested growth

Los hemangiomas de la infancia (HI) son tumo-res vasculares que presentan un patrón evolutivo característico. Existe un subgrupo de HI que pre-senta un tipo de crecimiento distinto denominados hemangiomas de la infancia con crecimiento míni-mo o detenido (HI-CMD). En estos, el componen-te proliferativo no supera el 25% de la superficie total; además, afecta a niños de al menos dos meses de edad en la consulta inicial o a niños menores de dicha edad en los que se realiza un seguimiento mayor a 2 meses. Los HI- CMD con lipoatrofia son una variante poco frecuente de HI de la cual exis-ten escasos reportes en la literatura. El objetivo de nuestro trabajo es presentar un caso de HI-CMD con lipoatrofia en una lactante. Los HI-CMD presentan un desafío diagnóstico ya que deben ser reconocidos precozmente y diferencia-dos de otras lesiones vasculares.

Infantile hemangiomas (IH) are vascular tumors that present a characteristic evolutive pattern. There is a subgroup of hemangiomas that pre-sents a different type of growth called infantile hemangiomas with minimal or arrested growth (IH-MAG). In these, the proliferative component does not exceed 25% of the total surface; it also affects children of at least two months of age in the initial consultation or children under that age in which a follow-up of more than 2 months is carried out. IH-MAG with lipoatrophy is a rare variant of IH of which there are few reports in the literature.The aim of our report is to present a case of IH-MAG with lipoatrophy in an infant. IH-MAGs present a diagnostic challenge since they must be recognized early, and differentiated from other vascular lesions.

Enfermedad de Paget extramamaria de la vulva: a propósito de un caso clínico / Extramammary Paget's disease of the vulva: apropos of a clinical case

La Enfermedad de Paget extramamaria de la vulva es una neoplasia poco frecuente que representa solo el 1% de los cánceres de vulva. Clínicamente, se caracteriza por una placa eritematosa, bien definida, con erosiones y ulceraciones. El síntoma más frecuente es el prurito. Esta clínica tan inespecífica puede retrasar el diagnóstico, además de inducir a tratamientos inadecuados. El diagnóstico se realiza con estudio histopatológico e inmunohistoquímica, la cual orienta si es primario de piel o metástasis de otro cáncer, usualmente genitourinario o gastrointestinal subyacente. Actualmente no hay guías clínicas de tratamiento, pero dentro de las opciones la más aceptada es la cirugía de Mohs. Otros tratamientos incluyen uso de imiquimod, láser CO2, quimioterapia tópica o local, radioterapia o terapia fotodinámica. Cuando se trata de una enfermedad de Paget extramamaria primaria, el pronóstico es excelente y la mayoría de los pacientes fallece por otra condición. En cuanto a la enfermedad invasora, tiene una mortalidad de 13-18% con sobrevida a 5 años de 72% (1)

Síndrome de sensibilidad a fármacos con eosinofilia y síntomas sistémicos en pediatría: Caso clínico / DRESS syndrome in paediatrics: Clinical case

El síndrome de sensibilidad a fármacos con eosinofilia y síntomas sistémicos es una enfermedad potencialmente mortal, caracterizada por exantema, fiebre, adenopatías, alteraciones hematológicas y compromiso de órganos internos. Objetivo: Presentar una afección poco frecuente en pediatría para facilitar la sospecha diagnóstica y el rápido reconocimiento por parte de los médicos. Caso clínico: Lactante de 9 meses hospitalizada por un cuadro de neumonía viral grave con ventilación mecánica no invasiva, tratada con ceftriaxona entre otros medicamentos. Al quinto día de suspendido el antibiótico presentó un exantema maculopapular violáceo, confluente de predominio en el tronco, la cara y las extremidades superiores, asociado a fiebre, eosinofilia y elevación de transaminasas. Se manejó con prednisona oral más corticoides tópicos por 6 semanas, con buena evolución a los 3 meses de seguimiento. Conclusiones: El diagnóstico de síndrome de sensibilidad a fármacos con eosinofilia y síntomas sistémicos se realiza por clínica y exámenes de laboratorio, además de biopsia cutánea en caso de duda diagnóstica. Si bien su causa más frecuente son los anticonvulsivantes se han descrito casos con un sinnúmero de fármacos. El manejo consiste en la suspensión del fármaco sospechoso asociado a medidas de soporte y tratamiento corticosteroide por tiempos prolongados.

Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare, potentially life-threatening, drug-induced hypersensitivity reaction that includes skin eruption, haematological abnormalities, lymphadenopathy, and internal organ involvement. Objective: Presenting a rare condition in children, to facilitate a rapid diagnostic suspicion and recognition by doctors. Case report: An 9 months old infant admitted due to a severe viral pneumonia, managed with non-invasive ventilation and ceftriaxone. Five days after stopping antibiotics, a confluent maculopapular rash appeared, which was predominantly in the trunk, face and upper extremities, combined with a fever, eosinophilia, and elevated serum levels of transaminase. She received treatment with oral prednisone and topical corticosteroids for 6 weeks, with a good outcome after 3 months. Conclusions: The diagnosis of DRESS syndrome is made using clinical criteria, laboratory values, and histopathology, if there is any query. Although it is classically caused by anticonvulsants and sulphonamides, many other drugs have been implicated. The offending drug should be immediately discontinued and the patient given supportive treatment, and systemic corticosteroids for long periods of treatment.

Oclusión intestinal por duplicación intestinal: diagnóstico y tratamiento en urgencias / Intestinal occlusion by intestinal duplication: diagnosis and treatment in the emergency

Las duplicaciones intestinales son anomalías congénitas; se han descrito a lo largo de todo el tracto digestivo con una presentación clínica inespecífica. Reportamos el caso clínico de un paciente de 83 años intervenido quirúrgicamente por una oclusión intestinal por duplicación intestinal del íleon terminal.

We report the clinical case of a patient of 83 years underwent surgery for an intestinal occlusion by intestinal duplication of the terminal ileum. We discuss the clinical presentation, image studies, surgical procedure and results of treatment. We review the current literature relevant to be a finding etiological diagnosis of intestinal occlusion rare.

Acidentes de trânsito envolvendo motoristas de caminhão no Estado de São Paulo: prevalência e preditores / Truck drivers’ traffic accidents in the State of São Paulo: prevalence and predictors

Resumo A taxa de mortalidade por acidentes de trânsito (AT) é alta no Brasil. Os caminhões são a segunda categoria de veículos automotores mais envolvida em AT, entretanto, poucos estudos focaram o tema entre esses profissionais. O objetivo do estudo foi estimar a prevalência de AT e preditores em uma amostra de 684 motoristas recrutados no Estado de São Paulo, durante 2012 e 2013. Os participantes foram solicitados a responder um instrumento de pesquisa sobre informações pessoais, ocupacionais e envolvimento em violações de trânsito e AT. Um modelo de regressão logística foi desenvolvido para identificar os preditores de AT. Quase 11% dos entrevistados sofreram algum AT no período. Os seguintes fatores preditores de AT foram identificados: poucos anos de experiência como motorista profissional (RC = 1,86; IC95% = 1,05-3,38; p = 0,036); cometer alguma multa de trânsito (RC = 1,91; IC95% = 1,04-3,66; p = 0,043) e trabalhar mais de doze horas diárias (RC = 1,84; IC95% = 1,04-3,24; p = 0,034). Diante desses resultados, sugerimos o desenvolvimento de uma ação conjunta entre todos os atores sociais envolvidos com fins de negociar a organização de trabalho dos motoristas de caminhão, visando então a redução da emissão de comportamentos que possam evoluir para acidentes de trânsito.

Abstract Abstract The mortality rate of traffic accidents (TA) is high in Brazil. Trucks are the second category of motor vehicles most often involved in TA. However, few studies have addressed the issue of TA among these professionals. The study aimed to estimate the prevalence of TA and their predictors in a sample of 684 truck drivers recruited in the state of São Paulo during 2012 and 2013. We requested participants to answer a research instrument on their personal and occupational data and their involvement in TA and traffic violations. A logistic regression model was developed to identify TA predictors. Almost 11% of the respondents suffered at least one TA in that timeframe. We identified the following TA predictors: having few years of experience as professional drivers (OR = 1.86; CI 95% = 1.05-3.38; p = 0.036); receiving some traffic tickets (OR = 1.91; CI 95% = 1.04-3.66; p = 0.043) and working more than 12 hours daily (OR = 1.84; CI 95% = 1.04-3.24; p = 0.034). Given those results, we suggest the development of a joint action among all the involved social stakeholders in order to negotiate truck drivers’ work organization aiming at reducing behaviors that may lead to traffic accidents.

Risk Factors for Cardiovascular Disease, Metabolic Syndrome and Sleepiness in Truck Drivers / Fatores de Risco para Doença Cardiovascular, Síndrome Metabólica e Sonolência em Motoristas de Caminhão

Abstract Background: Truck driver sleepiness is a primary cause of vehicle accidents. Several causes are associated with sleepiness in truck drivers. Obesity and metabolic syndrome (MetS) are associated with sleep disorders and with primary risk factors for cardiovascular diseases (CVD). We analyzed the relationship between these conditions and prevalence of sleepiness in truck drivers. Methods: We analyzed the major risk factors for CVD, anthropometric data and sleep disorders in 2228 male truck drivers from 148 road stops made by the Federal Highway Police from 2006 to 2011. Alcohol consumption, illicit drugs and overtime working hours were also analyzed. Sleepiness was assessed using the Epworth Sleepiness Scale. Results: Mean age was 43.1 ± 10.8 years. From 2006 to 2011, an increase in neck (p = 0.011) and abdominal circumference (p < 0.001), total cholesterol (p < 0.001), triglyceride plasma levels (p = 0.014), and sleepiness was observed (p < 0.001). In addition, a reduction in hypertension (39.6% to 25.9%, p < 0.001), alcohol consumption (32% to 23%, p = 0.033) and overtime hours (52.2% to 42.8%, p < 0.001) was found. Linear regression analysis showed that sleepiness correlated closely with body mass index (β = 0.19, Raj2 = 0.659, p = 0.031), abdominal circumference (β = 0.24, Raj2 = 0.826, p = 0.021), hypertension (β = -0.62, Raj2 = 0.901, p = 0.002), and triglycerides (β = 0.34, Raj2 = 0.936, p = 0.022). Linear multiple regression indicated that hypertension (p = 0.008) and abdominal circumference (p = 0.025) are independent variables for sleepiness. Conclusions: Increased prevalence of sleepiness was associated with major components of the MetS.

Resumo Fundamento: A sonolência de motoristas de caminhão, que pode resultar de diferentes causas, é a principal causa de acidentes com veículos. Obesidade e síndrome metabólica (SMet) estão associadas a distúrbios do sono e fatores de risco primários para doença cardiovascular (DCV). Este estudo verificou a relação entre essas condições e a prevalência de sonolência em motoristas de caminhão. Métodos: Este estudo analisou os principais fatores de risco para DCV, dados antropométricos e distúrbios do sono em 2.228 motoristas de caminhão do sexo masculino a partir de informação coletada de 148 paradas efetuadas em rodovias pela Polícia Rodoviária Federal entre 2006 e 2011. Consumo de álcool e de drogas ilícitas e excesso de horas trabalhadas também foram analisados. Sonolência foi avaliada com a Escala de Sonolência de Epworth. Resultados: A idade média foi de 43,1 ± 10,8 anos. De 2006 a 2011, observou-se aumento de: circunferências cervical (p = 0,011) e abdominal (p < 0,001); colesterol total (p < 0,001); níveis séricos de triglicerídeos (p = 0,014); sonolência (p < 0,001). Além disso, houve redução de hipertensão (de 39,6% para 25,9%, p < 0,001), consumo de álcool (de 32% para 23%, p = 0,033) e excesso de horas trabalhadas (de 52,2% para 42,8%, p < 0,001). A análise de regressão linear mostrou correlação íntima de sonolência com índice de massa corporal (β = 0,19, Raj2 = 0,659, p = 0,031), circunferência abdominal (β = 0,24, Raj2 = 0,826, p = 0,021), hipertensão (β = -0,62, Raj2 = 0,901, p = 0,002) e triglicerídeos (β = 0,34, Raj2 = 0,936, p = 0,022). Regressão linear múltipla indicou que hipertensão (p = 0,008) e circunferência abdominal (p = 0,025) são variáveis independentes para sonolência. Conclusões: Elevada prevalência de sonolência foi associada com os principais componentes da SMet.

Occupational conditions and the risk of the use of amphetamines by truck drivers / Condições ocupacionais e o risco de uso de anfetaminas entre motoristas de caminhão

OBJECTIVE To test whether the occupational conditions of professional truck drivers are associated with amphetamine use after demographic characteristics and ones regarding mental health and drug use are controlled for.METHODS Cross-sectional study, with a non-probabilistic sample of 684 male truck drivers, which was collected in three highways in Sao Paulo between years 2012 and 2013. Demographic and occupational information was collected, as well as data on drug use and mental health (sleep quality, emotional stress, and psychiatric disorders). A logistic regression model was developed to identify factors associated with amphetamine use. Odds ratio (OR; 95%CI) was defined as the measure for association. The significance level was established as p < 0.05.RESULTS The studied sample was found to have an average age of 36.7 (SD = 7.8) years, as well as low education (8.6 [SD = 2.3] years); 29.0% of drivers reported having used amphetamines within the twelve months prior to their interviews. After demographic and occupational variables had been controlled for, the factors which indicated amphetamine use among truck drivers were the following: being younger than 38 years (OR = 3.69), having spent less than nine years at school (OR = 1.76), being autonomous (OR = 1.65), working night shifts or irregular schedules (OR = 2.05), working over 12 hours daily (OR = 2.14), and drinking alcohol (OR = 1.74).CONCLUSIONS Occupational aspects are closely related to amphetamine use among truck drivers, which reinforces the importance of closely following the application of law (Resting Act ("Lei do Descanso"); Law 12,619/2012) which regulates the workload and hours of those professionals. Our results show the need for increased strictness on the trade and prescription of amphetamines in Brazil.

OBJETIVO Testar se as condições ocupacionais de motoristas profissionais de caminhão estariam associadas ao uso de anfetaminas após o controle do efeito de características demográficas, de saúde mental e uso de drogas.MÉTODOS Estudo transversal, com amostra não-probabilística de 684 motoristas de caminhão, do sexo masculino, recrutada em três rodovias do estado de São Paulo, durante os anos de 2012 e 2013. Foram coletadas informações demográficas, ocupacionais, sobre uso de drogas e sobre saúde mental (qualidade de sono, estresse emocional e transtornos psiquiátricos). Foi desenvolvido um modelo de regressão logística para identificar os fatores associados ao uso de anfetaminas. A razão de chances (OR; IC95%) foi definida como a medida de associação e o nível de significância considerado foi p < 0,05.RESULTADOS A amostra estudada apresentou idade média de 36,7 (DP = 7,8) anos e baixa escolaridade (8,6 [DP = 2,3] anos). O uso de anfetaminas nos doze meses prévios à entrevista foi autorrelatado por 29,0% dos motoristas. Após o controle do efeito de variáveis demográficas e ocupacionais, os fatores preditores do uso de anfetaminas entre os motoristas de caminhão foram: ter menos de 38 anos (OR = 3,69), menos de nove anos de escolaridade (OR = 1,76), ser autônomo (OR = 1,65), trabalhar em turno noturno ou turno irregular (OR = 2,05), trabalhar mais de 12 horas diárias (OR = 2,14) e usar álcool (OR = 1,74).CONCLUSÕES Os aspectos ocupacionais estão intimamente associados ao uso de anfetaminas entre motoristas de caminhão, reforçando a importância da fiscalização da lei (Lei do Descanso; Lei 12.619/2012) que regulamenta a carga horária de trabalho desses profissionais. Os resultados mostram a necessidade de haver maior rigor sobre a comercialização e prescrição das anfetaminas no Brasil.

A continuidade do uso de anfetaminas por motoristas de caminhão no Estado de São Paulo, Brasil, a despeito da proibição de sua produção, prescrição e uso / Persistent amphetamine consumption by truck drivers in São Paulo State, Brazil, despite the ban on production, prescription, and use / El uso continuado de anfetaminas por parte de los conductores de camión en el estado de São Paulo, Brasil, a pesar de la prohibición de su producción, prescripción y uso

O uso de anfetaminas por motoristas de caminhão com fins ocupacionais é amplamente reconhecido, entretanto, no mês de outubro de 2011, sua produção e uso foram proibidos através de uma resolução da Agência Nacional de Vigilância Sanitária (ANVISA). O objetivo deste estudo foi identificar o uso de anfetaminas entre motoristas de caminhão após a implementação da referida resolução. Uma amostra de conveniência de 427 motoristas de caminhão foi abordada em rodovias do Estado de São Paulo, Brasil, durante o ano de 2012. Os participantes foram solicitados a responder um instrumento de pesquisa estruturado, assim como fornecer uma amostra de urina para avaliar o uso recente de anfetaminas através de análise toxicológica. Entre os motoristas avaliados, 7% fizeram uso recente de alguma substância ilícita, dos quais 2,7% usaram anfetaminas. Aparte a periculosidade associada ao uso de anfetaminas, assim como a despeito da resolução que o regulamenta, esse uso continua entre os motoristas de caminhão. Assim, sugere-se que as autoridades competentes fiscalizem a posse, assim como o uso de anfetaminas no contexto do trânsito.

Amphetamine use by truck drivers for occupational purposes is widely known. The production and consumption of amphetamines was banned by the Brazilian National Health Surveillance Agency (ANVISA) in October 2011. This study analyzes persistent amphetamine use by truck drivers since the ban was implemented. A convenience sample of 427 truck drivers was taken along highways in São Paulo State in 2012. Participants were asked to answer a structured questionnaire and provide a urine sample to screen for recent amphetamine consumption through toxicological analysis. Among the interviewed drivers, 7% had used some illicit drug recently and 2.7% had used amphetamines. Amphetamines are still consumed by truck drivers despite the risks and the recent ban. The authorities should thus monitor the possession and use of amphetamines by drivers in order to effectively enforce the ban.

El uso de anfetaminas con fines profesionales entre los conductores de camiones es ampliamente reconocido, sin embargo, en octubre de 2011, su producción y uso fueron prohibidos por una resolución de la Agencia Nacional de Vigilancia Sanitaria (ANVISA). El objetivo de este estudio fue identificar el uso de anfetaminas entre conductores de camión después de la implementación de esa resolución. Una muestra de conveniencia compuesta por 427 conductores de camiones fue abordada en las carreteras del estado de São Paulo, Brasil, en el año 2012. A los participantes se les pidió rellenar una encuesta estructurada, así como dar una muestra de orina para determinar el consumo reciente de anfetaminas, a través de análisis toxicológico. Entre los conductores evaluados, el 7% consumió recientemente algún estupefaciente, de los cuales un 2,7% había consumido anfetaminas. Aparte de los peligros asociados al uso de anfetaminas, y de la resolución que lo regula, ese uso sigue vigente entre los conductores de camión. Por lo tanto, se sugiere que las autoridades competentes supervisen la posesión, así como el consumo de anfetaminas, en el tráfico rodado.

Uso de anfetaminas por motoristas de caminhão em rodovias do Estado de São Paulo: um risco à ocorrência de acidentes de trânsito? / Amphetamine use by truck drivers on highways of Sao Paulo State: a risk for the occurrence of traffic accidents?

The use of amphetamines in Brazil is common among truck drivers, which may be an important factor in the occurrence of traffic accidents. This article seeks to estimate the prevalence of amphetamine use among truck drivers. Drivers (N = 134) were stopped on two different highways in Sao Paulo state and they were asked to answer a questionnaire and provide a urine sample for toxicological analysis. All data were analyzed on Stata 8.0. All participants were males with low levels of schooling, whose mean age was 40.8 years. The presence of amphetamines was detected in 10.8% of all urine samples collected, being commonly justified in order to make truck drivers able to maintain their state of awareness. Amphetamine use was detected among truck drivers on Sao Paulo highways. The problem is that when the stimulant effects wear off, sleepiness due to sleep deprivation reduces concentration and good driver performance, making drivers vulnerable to traffic accidents and the related effects.

No Brasil, é comum o uso de anfetaminas por motoristas de caminhão, o que pode culminar na ocorrência de acidentes de trânsito. O objetivo deste artigo é estimar a prevalência do uso de anfetaminas entre caminhoneiros. Motoristas (N = 134) foram abordados em duas rodovias do Estado de São Paulo e solicitados a responder um questionário, assim como a fornecer uma amostra de urina para realização de análises toxicológicas. Todos os dados foram analisados em Stata 8.0. Todos os participantes eram do sexo masculino, de idade média de 40,8 anos e de baixa escolaridade. A presença de anfetaminas foi detectada em 10,8% das amostras de urina, cujo uso foi justificado para manter a vigília durante o trabalho. O uso de anfetaminas foi detectado entre caminhoneiros em rodovias de São Paulo. Cessado o efeito estimulante, a sonolência advinda de uma possível privação de sono diminui a atenção e o bom desempenho na direção, predispondo o condutor aos acidentes de trânsito e seus custos relacionados.

Efectos acústicos inmediatos de una secuencia de ejercicios vocales con tubos de resonancia / Immediate effects of a vocal exercise sequence with resonance tubes

OBJETIVO: el propósito de este estudio es conocer el efecto acústico inmediato de una secuencia de ejercicios fonatorios utilizando tubos de resonancia en un grupo de sujetos disfónicos. MÉTODO: se aplicó una secuencia única de cuatro tareas fonatorias dentro de tubos de resonancia a veinticuatro profesores con voces disfónicas, evaluadas perceptualmente con la escala GRBAS. Las muestras de voz fueron grabadas antes y después de la secuencia de ejercicios. El análisis acústico incluyó Cepstrum, Jitter, Shimmer y relación armónico-ruido (NHR). Se solitó completar un protocolo de autovaloración vocal posterior a la secuencia de ejercicios para evaluar los efectos subjetivos. Se compararon los valores de los parámetros acústicos en las muestras pre y post entrenamiento. RESULTADOS: cambios significativos fueron obtenidos en el análisis Cepstral, Jitter y relación armónico-ruido. En la autovaloración, los efectos positivos predominaron sobre los negativos, siendo los principales: voz más estable, voz más clara y garganta más abierta. CONCLUSIÓN: el uso de tareas fonatorias dentro de tubos de resonancia puede tener un efecto fisiológico terapéutico inmediato en sujetos con voces disfónicas y una percepción subjetiva de mejoría en la producción de la voz posterior a la terapia.

PURPOSE: the purpose of this study is to determine the immediately acoustic effect of phonatory exercise sequence using resonance tubes in a group of dysphonic subjects METHOD: a unique sequence of four phonatory tasks within resonance tubes was applied in twenty-four teachers with dysphonic voices, assessed perceptually with GRBAS scale. Voice samples were recorded before and after the exercise sequence. Acoustic analysis included the following items: Cepstrum, Jitter, Shimmer, noise-harmonic ratio (NHR). Subjects were asked to fill out a vocal self-assessment protocol after the exercise sequence in order to assess the subjective effects of these exercises. Acoustic parameters of voice samples pre and post training were compared. RESULTS: significant changes were obtained in the Cepstral analysis, jitter and harmonic-to-noise ratio. In the self-assessment, positive effects prevailed over the negative ones, being the main, as follows: more steady voice, more clear voice and more open throat sensation. CONCLUSION: the outcome indicates that the use of phonatory tasks with resonance tubes may have immediate therapeutic physiological effects on subjects with hoarse voices and a subjective perception of improvement in voice production after the therapy.
