Ethnodirigid study of Medicinal plants used by the population assisted by the Programa de Saúde da Família (Family Health Program) in Marechal Deodoro - AL, Brazil / Estudo etnodirigido de Plantas medicinais utilizadas pela população atendida no Programa de Saúde da Família, Marechal Deodoro, AL, Brasil

Abstract This study aimed to assess diagnosis of Unique Health System (SUS) users profile with regard to herbal medicine. This is a cross-sectional study with observational data collection conducted in the city of Marechal Deodoro, through a semi-structured questionnaire with questions related to socioeconomic data, use, and knowledge of medicinal plants and herbal medicines and satisfaction with the use of medicinal herbs (MH) and interactions of phytotherapeutic drugs (PD). Among the topics, 86.89% of users used herbal medicines often, especially lemon balm (Melissa officinalis L.). It was also observed that the plants are generally used as a sedative (21.74%) and as tea (87.84%). 82.32% of respondents claim to have acquired the knowledge of herbal medicine through a family member and 85.36% make use of medicinal plants without having received any information on the use of MH and PD. 61% of the plants described that coincided with the form of use and therapeutic properties found in the literature. With regard to satisfaction by treatment with MH and PD, it was found that 56.67% are satisfied. Therefore, it is necessary to pay attention to this aspect of usage, in order to avoid possible drug interactions or adverse reactions resulting from the incorrect use.

Resumo Este trabalho teve como objetivo conhecer perfil diagnóstico de usuários do SUS com relação à fitoterapia. Trata-se de um estudo observacional transversal, com coleta de dados realizada no Município de Marechal Deodoro, por meio de um questionário semi-estruturado com perguntas relativas a dados socioeconômicos, utilização e conhecimentos sobre plantas medicinais e fitoterápicos e satisfação com o uso de plantas medicinais (PM) e medicamentos fitoterápicos (MF). Entre os usuários abordados, 87,08% utilizam plantas medicinais frequentemente, principalmente a erva cidreira (Melissa officinalis L.). Também foi observado que as plantas são geralmente usadas como calmante (16,05%) e na forma de chá (68,35%). 82,51% dos entrevistados afirmam ter adquirido o conhecimento sobre fitoterapia através de algum familiar e 85,56% fazem uso das PM e MF sem ter recebido algum tipo de informativo sobre o seu uso. 61% das plantas descritas pelos usuários teve seu uso e terapêutica coincidente com o citado em literatura específica. Com relação a satisfação através do tratamento com PM e MF observou-se que 56,80% estão satisfeitos. O uso de plantas medicinais por parte dos usuários é bastante frequente, principalmente pelo conhecimento acumulado ao longo de gerações. Portanto, se faz necessária maior atenção a esse aspecto de utilização, visando evitar possíveis reações adversas advindas do uso incorreto.

Update on vasculitis: an overview and dermatological clues for clinical and histopathological diagnosis - part I

Abstract The term vasculitis refers to the inflammation of vessel walls. It may range in severity from a self-limited disorder in one single organ to a life-threatening disease due to multiple organ failure. It has many causes, although they result in only a few histological patterns of vascular inflammation. Vessels of any type and in any organ can be affected, a fact that results in a broad variety of signs and symptoms. Different vasculitides with indistinguishable clinical presentations have quite different prognosis and treatments. This condition presents many challenges to physicians in terms of classification, diagnosis, appropriate laboratory workup, and treatment. Moreover, it compels a careful follow-up. This article reviews the Chapel-Hill 2012 classification, etiology, recent insights in pathophysiology, some important dermatological clues for the diagnosis and summarizes treatment of some of these complex vasculitis syndromes.

Intervenciones terapéuticas en psicosis esquizofrénica de niños y adolescentes / Therapeutic interventions in schizophrenic psychosis in children and adolescents

La prevalencia de Esquizofrenia es muy baja en la infancia y adolescencia temprana, aumentando en la adolescencia y adultez a un 1%. Se ha estimado que la prevalencia de psicosis de 0,9 en 10.000 a los 13 años y 17,6 en 10.000 a los 18 años. Los cuadros esquizofrénicos de inicio temprano y muy temprano son una variante severa del trastorno y se asocian a un mayor deterioro funcional, curso clínico más grave y peor evolución. Todo esto determina la necesidad de implementar tratamientos multimodales tempranos y eficaces, así como estrategias preventivas en los grupos de mayor riesgo. El tratamiento farmacológico cuenta con mayores evidencias de efectividad en este cuadro y otorga notables beneficios a los pacientes, sin embargo se requiere mayor investigación a largo plazo respecto a los efectos adversos secundarios, su impacto en individuos en desarrollo y la eficacia de estos agentes. Estos avances permitirán al clínico establecer un justo balance costo/beneficio de su uso en población infantojuvenil.

The prevalence of schizophrenia is very low during childhood and early adolescence, increasing later in adolescence and adulthood to 1%. It has been established that the prevalence of psychosis is 0.9/10000 at 13 years of age and 17.6/10000 at 18 years of age. Early and very early onset schizophrenia are a severe form of this disorder, and are associated to a larger disability, more severe form of the disease and worse prognosis. These factors determine the need of implementing treatments that are multimodal, early and effective, as well as preventive strategies in high risk groups. The pharmacological treatment of schizophrenia has evidence of effectiveness and gives patients important benefits, however, more long term research is needed regarding its side effects, its impact on the developing brain and its effectiveness. These facts would help the psychiatrist to establish the value, risks and benefits of the use of drugs in children and adolescents.

Intervenciones terapéuticas en trastornos del desarrollo de la personalidad en niños y adolescentes / Therapeutic interventions in personality disorders in children and adolescents

La personalidad puede ser entendida como una organización dinámica de los sistemas biológicos, psicológicos y sociales que determinan los modos de relación del individuo con su ambiente y las experiencias subjetivas concomitantes, que cumple una función adaptativa al intentar armonizar las necesidades internas con las exigencias externas. Su desarrollo anormal y perturbado, delimita los Trastornos del Desarrollo de la Personalidad (TDP). El abordaje terapéutico de los TDP, incluye intervenciones de diversa índole: Psicoeducación, Psicoterapia Individual, Terapia de Grupo, Terapia Familiar, Hospitalización, Hospitalización diurna y Psicofarmacológica. Estas intervenciones deben integrarse en un dispositivo terapéutico altamente estructurado e integrado, incorporando las consideraciones del desarrollo. El presente artículo pretende presentar evidencia disponible respecto de las intervenciones terapéuticas en población Infanto Juvenil con diagnóstico de TDP.

Personality can be understood as a dynamic organization of biological, social and psychological systems, which determine the ways an individual interacts with his environment and his subsequent subjective experiences, and it serves an adaptative function in that it attempts to harmonize internal needs with external demands. Personality development disorders (PDD) are defined by the personality's development in an abnormal and disturbed path. The treatment of PDD includes different types of interventions, such as: psychoeducation, individual psychotherapy, group therapy, family therapy, hospitalization, day time hospitalization and psychopharmacotherapy. These interventions must be integrated to a highly structured therapeutic device that considers developmental issues. This article attempts to review the available evidence of therapeutic interventions in children and adolescents with a PDD diagnosis.

Estereotipos negativos de la vejez en personal de salud de un Hospital de la Ciudad de Querétaro, México / Prevalence of negative stereotypes towards old age among personnel of a general hospital

Background: Social representations are value systems. Social stereotypes are a social consensus of traits associated with a specific group. Stereotypes about older subjects, generally have negative connotations. Aim: To assess the prevalence of negative stereotypes towards older subjects among health care personnel. Material and Methods: A questionnaire about stereotypes towards old age, with Likert type questions that included health, social motivations and personality-character domains, was applied to 52 doctors, 12 residents, 80 general nurses, 36 auxiliary nurses, four social workers and 10 medical assistants, working at a general hospital. Results: The mean age of the professionals who answered the questionnaire was 38 years (95 percent confidence intervals (CI) 37-39 years) and 78 percent were women. The prevalence of a Global negative stereotype was 65.0 percent(95 percent CI: 59.5-70.5). The figure for the health domain was 64.5 percent (IC95 percent; 59.0-70.0), for the social motivation domain was 60 percent(5 percentCI: 54.3-65.7) and for the character personality domain was 64 percent (95 percentCI: 58.4-69.6). Conclusions: There is a high prevalence of a negative stereotype towards old age among health care personnel.

Evaluación de la actividad antioxidante y determinación del contenido de compuestos fenólicos en extractos de macroalgas del Caribe colombiano / Antioxidant activity evaluation and phenolic compound content determination of seaweeds extracts from the colombian Caribbean

Los antioxidantes son compuestos de gran interés en la actualidad por sus benéficas implicaciones para la salud humana. Dado que en hoy existe un marcado interés en la búsqueda de antioxidantes de fuentes naturales, como las algas marinas, en este trabajo se analizan los extractos metanólico y hexánico de cinco macroalgas Colombianas: Caulerpa mexicana, Laurencia sp., Sargassum sp., Dictyota sp. y Sargassum cymosum.Se determina su contenido de compuestos fenólicos totales siguiendo el método de Folin-Ciocalteau, y se mide su actividad captadora de radicales libres mediante el método del DPPH de los respectivos extractos.Los resultados muestran que todas las especies de macroalgas Colombianas estudiadas presentan actividad antioxidante, posiblemente asociada a su contenido de fenoles totales. La especie Sargassum cymosum es la que ofrece mayor rendimiento en cuanto a contenido de compuestos fenólicos, actividad captadora de radicales libres, y es la segunda en rendimiento en cuanto al contenido de compuestos solubles en metanol. Se demuestra así que los recursos marinos Colombianos representan una gran potencial en la búsqueda de sustancias con aplicación en el sector farmacéutico y alimentario.

Tumor cervical por enfermedad de Kikuchi: Una entidad clínica a la que no estamos habituados. Caso clínico / Histiocytic necrotizing lymphadenitis: Report of three cases

Histiocytic necrotizing lymphadenitis (HNL), also known as Kikuchi 5 disease is a rare condition of unknown etiology. Patients present with cervical lymph node enlargement, fever and malaise. The diagnosis is made by excision biopsy. However, this entity must be distinguished from both reactive processes and malignant tumors such as lymphoma. The clinical course is self limited with spontaneous resolution within a few months. We report three patients with the disease. A 37 year-old woman with a 4 months history of a painless submaxillary mass of 2.5 cm diameter, attached to the deep tissues of the neck. The mass was excised and the biopsy report was HNL. After 26 months of follow up, the patient is asymptomatic. A 30 year-old woman with a history of 2 months of a painless lateral cervical mass and aspiration biopsy was reported as suspicious for lymphoma. An excision biopsy was performed, that was reported as HNL. In both patients, lymphoma was ruled out by immunohistochemistry. A 33 year-old woman with a 3 weeks history of an asymptomatic lateral cervical mass. Biopsy was reported as HNL. This condition must be included in the differential diagnosis of cervical asymptomatic masses. The clinician must be aware of it to avoid long-term, costly treatments.

Enfermedad de Rosai-Dorfman (histiocitosis sinusal con linfadenopatías masivas): a propósito de un caso / Rosai-Dorfman disease: a case report

La enfermedad de Rosai-Dorfman es una patología histiocítica proliferativa que afecta a los ganglios linfáticos principalmente, sin embargo, un alto porcentaje de los pacientes tienen también afectación extraganglionar Presentamos el caso de una paciente de 64 años que consulta por múltiples tumores subcutáneos asociado a una discreta hiperpigmentación. Se realizan estudios histológicos donde se objetiva un infiltrado histiocitario con emperipolesis y con tinciones de inmunohistoquímica compatibles con enfermedad de Rosai-Dorfman. Se realiza una revisión del tema a propósito del caso.

Rosai-Dorfman disease is an histiocytic proliferative entity that affects mainly Iymph nodes, however a high percentage of patients also have extranodal involvement. We present the case of a 64-year-old woman with multiple subcutaneous tumors asso-ciated with a discrete hyperpigmentation. Histological reports revealed histiocytic proliferation with emperipolesis and immunohistochemical stains were consistent with Rosai-Dorfman disease. A review of related literature is presented.

¿Existen nódulos coloidos tiroideos que no requieren punción diagnóstica? / Are there any colloid thyroid nodules which do not require diagnostic punctures?

Depending on age, sex, and geographic area, 19 to 67% of the general population is found to have thyroid nodules when submitted to ultrasonica-lly-guided diagnostic puncture. Being benign in more than a 80%, most of them corresponds to colloid nodules. Indiscriminate fine-needle aspiration not only increases health costs but also generates anxiety in patients. The echographic-histological correlation of thyroid nodules made it possible to define five typical patterns (colloid patterns 1, 2, 3; neoplastic type, and malignant pattern). Thirty three percent of colloid nodules may appear as follicular neoplasms or malign nodules, being puncture the only means for recognizing and establishing the difference between them. Nevertheless, 67% of nodules presents a typical appearance that corresponds to colloid patterns 1, 2, and 3, which show a weak association to cancer risk(0%, 0% and 1,5%, respectively). On this basis, ultrasound follow-up is advised to recognize them in order to significantly diminish unnecessary diagnostic histological punctures.

En el 19 al 67%> de la población general se diagnostican nodulos tiroideos mediante ultra-sonografía, dependiendo de la edad, sexo y área geográfica. En más del 80% su naturaleza es benigna y la gran mayoría corresponde a nodulos coloideos. Su punción indiscriminada aumenta costos y genera ansiedad. La correlación ultrasonográfica-histológica de los nodulos tiroideos permitió definir cinco patrones característicos (patrón coloideo típico tipos 1 a 3, patrón neoplásico y patrón maligno). El 33%> de los nodulos coloideos simula la apariencia de nodulos de tipo neoplasia folicular o de aspecto maligno y sólo con punción se puede diferenciar entre ellos. No obstante, el 67%> de los nodulos tiene aspecto típico y corresponden a patrones coloideos Tipo 1, 2 y 3, con una baja asociación con cáncer (0%, 0%y 1,5% en los tres grupos respectivamente), lo que autoriza su seguimiento ultrasonográfico. Al reconocerlos como tal, se puede disminuir en forma significativa las punciones diagnósticas innecesarias.

Coexistencia de neuroblastoma olfatorio y aneurisma de la arteria carótida interna: presentación de un caso / Coexistence of an olfactory neuroblastoma and internal carotid artery aneurism: case report

El neuroblastoma olfatorio es una neoplasia neuroectodérmica maligna rara que afecta a la bóveda nasal y que tiende a invadir las estructuras vecinas, entre estas a la cavidad intracraneal. Su asociación con aneurismas intracraneales nunca ha sido descrita. Presentamos a una paciente con la coexistencia de un aneurisma del segmento oftálmico de la arteria carótida interna y un neuroblastoma olfatorio con invasión intracraneal. La coexistencia entre neoplasias del sistema nervioso central y aneurismas intracraneales es infrecuente. En este artículo analizamos las posibles causas de la asociación entre neoplasias y aneurismas intracraneales.

The olfactory neuroblastoma is a rare malignant neuroectodermal neoplasia of the nasal roof. It has a highly tendency of invades near structures including intracranial compartment. Associations between olfactory neuroblastoma with intracranial aneurysms have been never described. We show a case of a female with coexistence of an internal carotid artery aneurysm and olfactory neuroblastoma. The coexistence between nervous system tumors with intracranial aneurysms is not common. In this paper we analyze the association between intracranial neoplasia and aneurysms.

Densidade mineral óssea em cadelas submetidas à ovarioisterectomia com e sem reposição estrogênica oral / Mineral density in bones of ovariohysterectomized bitches, with or without oral estrogen replacement / Mineral density in bones of ovariohysterectomized bitches, with or without oral estrogen replacement

Estudaram-se os efeitos da ovarioisterectomia na densidade mineral óssea de cadelas e da reposição de estrógenos após a cirurgia. Foram utilizadas 12 cadelas, sem raça definida, entre dois e seis anos de idade e pesos entre 5 e 15kg. Os animais, submetidos à ovarioisterectomia, foram separados em dois grupos de seis. Um grupo serviu como controle, e o outro recebeu estrógenos naturais conjugados na dose de 0,01mg/kg via oral a cada 48 horas, durante 12 meses. No dia da cirurgia e após 12 meses, foram feitas radiografias com vistas à densitometria óptica em imagem radiográfica. A ovarioisterectomia diminuiu a densidade óssea, e a reposição estrogênica, na dose utilizada, foi capaz de preservá-la.

Effects on bone density of ovariohysterectomy and post-operative estrogen replacement were studied in bitches. Twelve mixed-breed bitches, ranging from 2 to 6 years of age and weighing between 5 and 15kg were submitted to ovariohysterectomy and separated in two groups of six, after a period of adaptation of 60 days. Bitches from the first group were an un-innoculated control; whereas treated bitches received 0.01mg/kg per os of natural estrogen every 48 hours for 12 months. Radiographs were taken on the day of surgery and 12 months later. Variation in bone density was quantified by optic densitometry in radiographic images. Ovariohysterectomy decreased bone density, whereas estrogen replacement moderated the effect.

O autor em trabalho realizado em Lábrea, Estado do Amazonas, Brasil, feito em 311 escolares, encontrou 95,4 por cento de positividade podendo-se destacar, em ordem decrescente, como de maior freqüência Ascaris lumbricoides 89,7 por cento, T. trichiura 64,3 por cento, ancilostomideos 51,7 por cento e Strongyloides stercoralis 10,6 por cento. Em relação aos protozoários apenas foi observado 9,0 por cento de positividade e como mais freqüentes E. coli 4,8 por cento, Giardia lamblia 2,5 por cento, sòmente em duas oportunidades foi revelado E. histolytica. Foram empregados dois métodos diretos: a) fezes diluídas em solução salina (cloreto de sódioa 0,85 por cento) b) fezes diluídas em Lugol de Weigert. Para confirmação diagnóstica de protozoários foi usada a coloração pela hematoxilina férrica. São apresentados dois quadros nos quais é mostrada a incidência por espécie e por grupo etário, em números e percentual.

The author presents the result of an intestinal parasites survey made in Lábrea town, Amazonas State, Brazil. Stool samples were examined from 311 school individuals, between the ages of five and 19 years. The survey showed an intestinal helminth rate of 95.4 percent. The incidence of other intestinal helminth was as follows: A. lumbricoides 89.7 percent, T. trichiura 64.3 percent, hookworms 51.7 percent, S. stercoralis 10.6 percent.The same stool specimens showed the rate of 9.0 percent for human intestinal protozoa. The most frequent was E. coli 4.8 percent; Giardia lamblia showed a rate of 2.5 percent. E. histolytica appeared in only two of all examinations.Two methods were used: a) direct examination in saline solution (0,85 percent) b)feces diluted in Weigert’s lugol. For differential diagnosis of protozoa, iron hematoxilin was used.Two tables are presented showing the incidence of all parasites found by species, number, percentage and age group.
