Functional dyspepsia treated with acupuncture of different frequencies: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy of acupuncture with different frequencies in the treatment of patients with functional dyspepsia (FD).@*METHODS@#A total of 90 patients with FD were randomly divided into a 3-time acupuncture treatment per week group (3-A group, 31 cases, 2 cases dropped off), a 1-time acupuncture treatment per week group (1-A group, 30 cases, 2 cases dropped off) and a control group (29 cases, 2 cases dropped off). In the two acupuncture groups, the acupoints were Zhongwan (CV 12) and bilateral Tianshu (ST 25), Neiguan (PC 6), Liangqiu (ST 34), Yanglingquan (GB 34), Zusanli (ST 36) and Taichong (LR 3), stimulated 3 times a week and once a week, respectively; and the treatment was given consecutively for 4 weeks. In the control group, no intervention was adopted, but the compensatory therapy was provided after the end of follow-up. The scores of the symptom index of dyspepsia (SID), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were compared among the 3 groups before treatment, after 4 weeks of treatment and in 4 and 8 weeks after treatment completion separately. The score of Nepean dyspepsia life quality index (NDLQI) was evaluated before treatment, after 2 and 4 weeks of treatment and in 4 and 8 weeks after treatment completion.@*RESULTS@#After 4 weeks of treatment and in 4 and 8 weeks after treatment completion, the scores of SID, SAS and SDS were all reduced in the 3-A group and the 1-A group when compared with the scores before treatment (P<0.000 1, P<0.05). After 4 weeks of treatment, the scores of SID, SAS and SDS in the two acupuncture groups were lower than those in the control group (P<0.000 1). After 2 and 4 weeks of treatment, the increased values of NDLQI score in the two acupuncture groups were all higher than those in the control group (P<0.05). In 4 and 8 weeks after treatment completion, the scores of SID, SAS and SDS in the 3-A group were lower than those in the 1-A group (P<0.001, P<0.05), and the increased values of NDLQI score in the 3-A group were higher than those in the 1-A group (P<0.000 1).@*CONCLUSION@#Acupuncture given 3 times per week is superior to the treatment given once per week in the aspects of relieving the clinical symptoms, improving the quality of life and regulating the emotional state in patients with FD. This efficacy is persistent for 8 weeks after treatment completion.

Effect of electroacupuncture at "Zusanli" (ST 36) on duodenal mast cells, NGF and NTRK1 in rats with functional dyspepsia / 中国针灸

OBJECTIVE@#To observe the effect of electroacupuncture (EA) at "Zusanli" (ST 36) on duodenal mast cells, nerve growth factor (NGF) and neurotrophic tyrosine kinase receptor type 1 (NTRK1), and to explore the mechanism of electroacupuncture at Zusanli (ST 36) on functional dyspepsia (FD).@*METHODS@#Sixty SPF-grade 10-day-old SD rats were randomly divided into a normal group, a model group, a ketotifen group and an EA group, 15 rats in each group. The FD model was prepared by iodoacetamide combined with rat tail clamping method in the model group, the ketotifen group and the EA group. The rats in the ketotifen group were injected intraperitoneally with ketotifen (1 mg•kg-1•d-1) for 7 days; the rats in the EA group were treated with EA at bilateral "Zusanli" (ST 36), with disperse-dense wave, frequency of 2 Hz/50 Hz and intensity of 0.5 mA, 20 min each time, once a day for 14 days. The gastric emptying rate and small intestinal propulsion rate in each group were observed; the morphology of duodenal mucosa was observed by HE staining; the toluidine blue staining was used to observe the number and degranulation of mast cells in duodenal mucosa; the protein and mRNA expressions of NGF, NTRK1 in duodenum were detected by Western blot and real-time PCR; the level of interleukin-1β (IL-1β) in duodenum was measured by ELISA.@*RESULTS@#Compared with the normal group, the gastric emptying rate and small intestinal propulsion rate in the model group were decreased (P<0.01); compared with the model group, the gastric emptying rate and small intestinal propulsion rate in the ketotifen group and the EA group were increased (P<0.01); the small intestinal propulsion rate in the EA group was higher than that in the ketotifen group (P<0.01). In the model group, local defects in duodenal mucosa were observed with a small amount of inflammatory cell infiltration; no obvious abnormality was found in duodenal mucosa of the other groups. Compared with the normal group, the mast cells of duodenal mucosa in the model group were increased significantly with significant degranulation; compared with the model group, the mast cells of duodenal mucosa in the ketotifen group and the EA group were decreased significantly, and the degranulation was not obvious. Compared with the normal group, the protein and mRNA expressions of NGF, NTRK1 as well as the level of IL-1β in duodenum in the model group were increased (P<0.01); compared with the model group, the protein and mRNA expressions of NGF, NTRK1 as well as the levels of IL-1β in duodenum in the ketotifen group and the EA group were decreased (P<0.01, P<0.05); compared with the ketotifen group, the mRNA expression of NGF, as well as the protein and mRNA expressions of NTRK1 in duodenum in the EA group were decreased (P<0.05, P<0.01).@*CONCLUSION@#EA at "Zusanli" (ST 36) could inhibit the activation of duodenal mast cells and regulate the expressions of NGF and its receptor to improve the low-grade inflammatory response of duodenum, resulting in treatment effect on FD.

Enfoque diagnóstico y terapéutico de dispepsia y dispepsia funcional: ¿qué hay nuevo en el 2019? / Diagnostic and therapeutic approach to dyspepsia and functional dyspepsia: what's new in 2019?

La dispepsia abarca un conjunto de síntomas que se originan en la región gastroduodenal. Se caracteriza por dolor o ardor epigástrico, saciedad precoz y llenura pos-prandial. Según la relación de los síntomas con las comidas se divide en síndrome de dolor epigástrico y síndrome de malestar pos-prandial. Sin embargo, en la práctica clínica, frecuentemente se sobreponen. En los últimos años se ha cambiado el paradigma de las alteraciones fisiológicas gástricas y han aumentado las evidencias que apoya a la eosinofilia duodenal, como una alteración primaria que altera la fisiología gástrica y puede inducir la sintomatología. Así mismo, cada día hay mayor interés en la alteración de la microbiota. El tratamiento se basa en la supresión de ácido, procinéticos, neuromoduladores, psicoterapia, terapias alternativas y complementarias. Ningún tratamiento es universalmente eficaz en todos los pacientes.

Dyspepsia encompasses a set of symptoms that originate in the gastroduodenal region. It is characterized by pain or epigastric burning, early satiety and post-prandial fullness. According to the relationship of symptoms with meals, it is divided into epigastric pain syndrome and postprandial distress syndrome. However, in clinical practice, they frequently overlap. In recent years the paradigm of gastric physiological alterations has been changed and evidence supporting duodenal eosinophilia has increased, as a primary alteration that alters gastric physiology and can induce symptomatology. Every day there is more interest in the alteration of the microbiota. The treatment is based on the suppression of acid, neuromodulators, prokinetics, psychotherapy, alternative and complementary therapies. No treatment is effective in all patients.

Mexican consensus on dyspepsia / Consenso mexicano sobre la dispepsiaMexican consensus on dyspepsia

Desde la publicación de las guías de dispepsia 2007 de la Asociación Mexicana de Gastroenterología ha habido avances significativos en el conocimiento de esta enfermedad. Se realizó una revisión sistemática de la literatura en PubMed (01/2007 a 06/2016) con el fin de revisar y actualizar las guías 2007 y proporcionar nuevas recomendaciones basadas en evidencia. Se incluyeron todas las publicaciones en español e inglés, de alta calidad. Se redactaron enunciados que fueron votados utilizando el método Delphi. Se estableció la calidad de la evidencia y la fuerza de las recomendaciones según el sistema GRADE para cada enunciado. Treinta y un enunciados fueron redactados, votados y calificados. Se informan nuevos datos sobre definición, clasificación, epidemiología y fisiopatología. La endoscopia debe realizarse en dispepsia no investigada cuando hay datos de alarma o falla al tratamiento. Las biopsias gástricas y duodenales permiten confirmar infección por Helicobacter pylori y excluir enfermedad celiaca, respectivamente. Establecer una fuerte relación médico-paciente, cambios en la dieta y en el estilo de vida son útiles como medidas iniciales. Los bloqueadores H2, inhibidores de la bomba de protones, procinéticos y fármacos antidepresivos son efectivos. La erradicación de H. pylori puede ser eficaz en algunos pacientes. Con excepción de Iberogast y rikkunshito, las terapias complementarias y alternativas carecen de beneficio. No existe evidencia con respecto a la utilidad de prebióticos, probióticos o terapias psicológicas. Los nuevos enunciados proporcionan directrices basadas en la evidencia actualizada. Se presenta la discusión, el grado y la fuerza de la recomendación de cada uno de ellos.

Abstract Since the publication of the 2007 dyspepsia guidelines of the Asociación Mexicana de Gastroenterología, there have been significant advances in the knowledge of this disease. A systematic search of the literature in PubMed (01/2007 to 06/2016) was carried out to review and update the 2007 guidelines and to provide new evidence-based recommendations. All high-quality articles in Spanish and English were included. Statements were formulated and voted upon using the Delphi method. The level of evidence and strength of recommendation of each statement were established according to the GRADE system. Thirty-one statements were formulated, voted upon, and graded. New definition, classification, epidemiology, and pathophysiology data were provided and include the following information: Endoscopy should be carried out in cases of uninvestigated dyspepsia when there are alarm symptoms or no response to treatment. Gastric and duodenal biopsies can confirm Helicobacter pylori infection and rule out celiac disease, respectively. Establishing a strong doctor-patient relationship, as well as dietary and lifestyle changes, are useful initial measures. H2-blockers, proton-pump inhibitors, prokinetics, and antidepressants are effective pharmacologic therapies. H. pylori eradication may be effective in a subgroup of patients. There is no evidence that complementary and alternative therapies are beneficial, with the exception of Iberogast and rikkunshito, nor is there evidence on the usefulness of prebiotics, probiotics, or psychologic therapies. The new consensus statements on dyspepsia provide guidelines based on up-to-date evidence. A discussion, level of evidence, and strength of recommendation are presented for each statement. © 2017 Asociacion Mexicana de Gastroenterologiia.

Dispepsia / Dyspepsia

Etmologicamente, a palavra dispepsia (do grego dis = difícil e pepse = digestão) significa digestão difícil. Sob o ponto de vista clínico, corresponde a uma série de sintomas de origem gastroduodenal, como dor, queimação ou desconforto epigástrico, plenitude pós-prandial ou saciedade precoce associadas ou não a náusea, vômitos e distensão em andar superior do abdome. Traduz, pois, um distúrbio funcional ou orgânico, de localização epigástrica e origem gastroduodenal...

Etymologically, the greek word dis means hard and pepse means digestion. Therefore, dyspepsia is a poor digestion. From the clinical point of view, dyspepsia corresponds to a range of symptoms originated from gastroduodenal, like pain, heartburn or epigastric discomfort, postprandial fullness or early fullness related or not to nausea, vomiting, upper abdominal distension. So, this explain that a functional or organic decline situated at the epigastric area and it is originated from gastroduodenal...

Acupuncture effcctiveness as a complementary therapy in functional dyspepsia patients / Eficacia da acupuntura como terapia complementar em pacientes com dispepsia funcional

Context Functional dyspepsia represents a frequent gastrointestinal disorder in clinical practice. According to the Roma III criteria, functional dyspepsia can be classified into two types as the predominant sympton: epigastric pain and postprandial discomfort. Even though the pathophysiology is still uncertain, the functional dyspepsia seems to be related to multiple mechanisms, among them visceral hypersensitivity, changes in the gastroduodenal motility and gastric accommodation and psychological factors. Objective Evaluate the effectiveness of acupuncture as a complementary to conventional treatment in functional dyspepsia patients. Methods Randomized clinical trial in which were enrolled patients with functional dyspepsia patients in according with Rome III criteria. One group was submitted to drug therapy and specific acupuncture (GI) and the other to drug therapy and non-specific acupuncture (GII). The gastrointestinal symptoms, presence of psychiatric disorders and quality of life were evaluated, at the end and three months after treatment. Results After 4 weeks of treatment there was improvement of gastrointestinal symptoms in Group I (55 ± 12 vs 29 ± 8.8; P = 0.001) and Group II (50.5 ± 10.2 vs 46 ± 10.5; P = 0.001). Quality of life was significantly better in Group I than group II (93.4 ± 7.3 vs 102.4 ± 5.1; P = 0.001). Anxiety (93.3% vs 0%; P = 0.001) and depression (46.7% vs 0%; P = 0.004) were significantly lower in Group I than group II. When comparing the two groups after 4 weeks of treatment, gastrointestinal symptoms (29 ± 8.8 vs 46 ± 10.5; P<0.001) and quality of life (102.4 ± 5.1 vs 96 ± 6.1; P = 0.021) were significantly better in Group I than group II. Three months after the treatment, gastrointestinal symptoms remained better only in Group I, when compared to the pre-treatment values (38 ± ...

Contexto A dispepsia funcional representa uma frequente desordem gástrica da prática clínica. Segundo os critérios de Roma III, pode ser subdividida em dois tipos: do tipo dor epigástrica e tipo desconforto pós prandial, de acordo com o sintoma predominante. Embora de fisiopatologia incerta, a dispepsia funcional parece estar relacionada a múltiplos mecanismos, entre eles: a hipersensibilidade visceral, alterações da motilidade gastroduodenal e acomodação gástrica e participação de fatores psíquicos. Objetivos Avaliar a eficácia da acupuntura como forma complementar ao tratamento medicamentoso em pacientes com dispepsia funcional. Método Ensaio clínico randomizado, com portadores de dispepsia funcional, segundo os critérios de Roma III. Dois grupos foram formados: Grupo I (terapia medicamentosa e acupuntura específica) e; II (terapia medicamentosa e acupuntura não específica). Foram avaliados o índice de sintomas gastrointestinais, a presença de transtornos psíquicos e a qualidade de vida no início, no fim e 3 meses após o tratamento. Resultados Após 4 semanas de tratamento houve melhora dos sintomas gastrointestinais no Grupo I (55 ± 12 vs 29 ± 8,8; P = 0,001) e no Grupo II (50 ± 10 vs 46 ± 10,5; P = 0,001). Na comparação intergrupos, os sintomas gastrintestinais (29 ± 8,8 vs 46 ± 10,5; P<0,001) e os sintomas de ansiedade (0% vs 41,7%; P = 0,003) foram significativamente menores no Grupo I e a qualidade de vida (102,4 ± 5,1 vs 96,4 ± 6,1; P = 0,021) também foi significativamente melhor neste grupo. Três meses após o tratamento, os sintomas gastrointestinais permaneceram melhores no Grupo I, quando comparados aos valores pré-tratamento (38 ± 11,3 vs 55 ...

Dispepsia funcional: diagnóstico e tratamento / Functional dispepsy: diagnosis and treatment

Dispepsia Funcional é a causa mais frequente das dispepsias. Sua fisiopatologia permanece obscura e ainda não dispomos de um método diagnóstico específico. Além disso, há uma ampla lista de diagnósticos diferenciais de doenças as quais também cursam com dispepsia. O tratamento muitas vezes tem benefícios discretos, e deve ser individualizado sempre que possível, juntamente com uma boa abordagem psicossocial, a qual pode auxiliar na terapêutica e no manejo destes pacientes.

Funcional Dyspepsia is the most frequent cause of dyspepsia. Its pathophysiology remains unclear and there is not still a specific diagnostic method. Moreover, there is an extensive list of differential diagnosis of diseases which also presents with dyspepsia. The treatment often has discrete benefits and must be individually whenever possible, with good psychosocial, which can aid in the treatment and the management of these patients.

Gastroparesia y dispepsia funcional: diagnóstico y tratamiento / Gastroparesis and functional dyspepsia: diagnosis and treatment

Gastroparesis corresponds to the clinical picture of a non-obstructive alteration in gastric emptying. The most common causes are idiopathic, postsurgical and diabetes mellitus. Endoscopy and gastric emptying scintigraphy are necessary for diagnosis. Fractionating the diet and avoiding fat are recommended actions. Prokinetics are fundamental in gastroparesis therapy. Domperidone is the first choice because it has a better safety profile. It is advisable to rotate prokinetics. In refractory cases it is suggested to try other prokinetics (such as erythromycin or prucalopride), effective management of nausea and nutrition optimization. In selected cases, therapies such as electrical stimulation could be evaluated. Functional dyspepsia is defined as symptoms that probably originate in the gastroduodenal region, having ruled out other possibilities. Therefore, endoscopy should show no alterations that could explain the symptoms. The most frequently encountered pathophysiological alterations are slow gastric emptying, impaired accommodation and hypersensitivity. None has been linked unequivocally to a pattern of symptoms. It is suggested to start with proton-pump inhibitors therapy. In refractory cases, prokinetics should be added. If there is no adequate response, 24-hour pH monitoring and gastric emptying should be ordered. In case of altered gastric emptying, adjust prokinetics. If gastric emptying is normal, bupirone or mianserin could be used.

La gastroparesia corresponde a un cuadro clínico debido a mal vaciamiento gástrico no obstructivo del estómago. Sus causas más frecuentes son idiopática, diabetes mellitus y postquirúrgica. La endoscopia y el cintigrama de vaciamiento gástrico son necesarios para el diagnóstico. Se recomienda fraccionar la dieta y evitar las grasas. Los procinéticos son fundamentales en el tratamiento de la gastroparesia. La domperidona es la primera opción por su mejor perfil de seguridad. Es aconsejable rotar los procinéticos. En casos refractarios se puede intentar otros procinéticos (como eritromicina o prucalopride), manejar específicamente las náuseas y optimizar la nutrición. En casos seleccionados se puede intentar terapias como estimulación eléctrica. La dispepsia funcional está definida por síntomas que probablemente se originan en la región gastroduodenal, habiendo descartado otras posibilidades. Por esto, requiere un estudio endoscópico sin alteraciones que expliquen los síntomas. Los hallazgos fisiopatológicos más frecuentemente encontrados son alteraciones del vaciamiento gástrico, trastornos de la acomodación e hipersensibilidad. Ninguno de ellos ha sido asociado inequívocamente a algún patrón de síntomas. Se sugiere iniciar tratamiento con inhibidores de la bomba de protones. En casos refractarios, es aconsejable agregar procinéticos. Si no hay adecuada respuesta, se sugiere estudiar con una ph-metría de 24 horas y vaciamiento gástrico. En caso de vaciamiento alterado, ajustar los procinéticos. En caso de vaciamiento normal, se sugiere uso de buspirona o mianserina.

Alcachofra / Artichoke

Introdução: A alcachofra é uma planta utilizada na culinária e dita com diversas propriedades medicinais.Objetivo: Verificar evidências do uso da alcachofra no tratamento de doenças.Métodos: Busca sistematizada da literatura por meio eletrônico, incluindo estudos que avaliem o uso da alcachofra namedicina.Resultados: Uma revisão sistemática mostrou resultados favoráveis a alcachofra na redução do colesterol total[intervalo de confiança (IC) de 0,40 a 0,79] e do LDL-colesterol (IC de 0,34 a 0,78). Dois ensaios clínicos randomizadoschegaram à mesma conclusão. Um estudo clínico mostrou benefício do uso da alcachofra em pacientes com síndromedo intestino irritável e outro mostrou que ela pode ser útil nas dispepsias funcionais. Um ensaio clínico constatou oaumento da atividade antioxidante total em remadores submetidos ao estresse físico e suplementados com alcachofra.Em todos os estudos não há ocorrência de efeitos adversos.Conclusão: Os estudos encontrados mostram evidências de uma ação benéfica da alcachofra nas hiperliproteinemias e nadispepsia funcional. Como sua eficácia é dose-dependente, não se pode depender apenas da ingestão de alcachofra por meioda alimentação. Os dislipidêmicos e dispépticos funcionais terão que se utilizar dos extratos vendidos comercialmente.

Pautas para reducir el número de prescripciones inadecuadas en pacientes con dispepsia / Guidelines to cut the number of inappropriate prescriptions in dyspepsia patients

Se considera demostrado que diferentes métodos de implementación dan como resultado un mayor o menor grado de aceptación de las pautas en atención primaria. Este estudio analiza el efecto sobre los gastos estimados en medicamentos a partir de tres métodos distintos de implementar las mismas pautas, utilizados en tres grupos diferentes de médicos generalistas. La investigación estuvo basada en: un método de implementación negociado, de nueve meses de duración (con incentivos económicos para completar el programa) (proyecto A); una sesión de un día de entrenamiento basado en la evidencia llevada adelante por colegas en pequeños grupos de trabajo (proyecto B); una reunión de aplicación conducida por un experto (proyecto C). Para cada proyecto comparamos los gastos estimados mensuales en inhibidores de la bomba de protones (IBP) y antagonistas de los receptores de histamina (ARH2) por cada mil pacientes registrados de los médicos generalistas (MG) que participaron con los de un grupo de MG de control, antes y después de implementar las pautas. Los 58 MG involucrados en el proyecto A redujeron las prescripciones en IBP alrededor del 26% (4 564 euros vs. 6 201 euros para 222 controles, p = 0.057) y de ARH2 alrededor de 30% (954 vs. 1 365 euros; p = 0.026). Los 101 MG que participaron del proyecto B prescribieron 5 535 euros en IBP y 556 euros en bloqueantes H2, mientras que los 61 MG controles hiceron prescripciones por 5 732 y 706 euros, respectivamente (lo que significó un ahorro del 3% en IBP y 21% en ARH2; p = ns). Los 15 MG que estuvieron en el proyecto C prescribieron 2 479 euros en IBP y 1 258 euros en ARH2, lo que implica un gasto 12% superior en IBP y una reducción del 17% en ARH2 cuando se los compara con los 2 215 euros empleados en IBP y 1 524 euros en bloqueantes H2 por los 270 MG del grupo control (p = ns)...

Dispepsia funcional: nuevos conocimientos en la fisiopatogenia con implicaciones terapéuticas / Functional dyspepsia: new pathophysiologic knowledge with therapeutic implications

La dispepsia funcional (DF) es un complejo sintomático, heterogéneo y altamente prevalente en la comunidad y en la práctica general. La DF se define como la presencia de síntomas que se piensan originados en la región gastroduodenal, en ausencia de enfermedad orgánica, sistémica o metabólica que pueda explicarlos. Entre los factores fisiopatogénicos se incluyen los trastornos de la acomodación y del vaciamiento gástrico, dismotilidad duodenal, sensibilidad aumentada, factores psicosociales y una asociación con un estado postinfeccioso. Se han hecho numerosos esfuerzos para aumentar los conocimientos en la etiopatogenia del síndrome, incluyendo nuevos aspectos moleculares y genéticos. Sin embargo, el mecanismo etiopatogénico exacto que causa los síntomas en un paciente individual sigue siendo difícil de identificar. Los nuevos criterios de Roma III redefinen y subclasifican la DF basándose en sus síntomas principales, lo cual es de gran valor para la investigación, el desarrollo y el control estandarizados de nuevas estrategias terapéuticas así como la formulación de recomendaciones para la práctica clínica. Las modalidades terapéuticas que se han empleado incluyen: modificaciones dietéticas, agentes farmacológicos dirigidos a actuar sobre distintos blancos dentro del aparato gastrointestinal, del sistema nervioso central y periférico, y terapias psicológicas incluyendo la hipnoterapia. Desafortunadamente, hasta la fecha, todas estas terapias han rendido solamente resultados marginales. Después de excluir enfermedad orgánica, es esencial que el paciente esté informado sobre la naturaleza y el pronóstico benignos de su enfermedad, y esto puede ser, a veces, la inversión más provechosa tanto para el paciente como para su médico.

Functional dyspepsia (FD) is a heterogeneous, highly prevalent symptom complex in the community and general practice. FD is defined as the presence of symptoms considered as originated in the gastroduodenal region, in the absence of any organic, systemic, or metabolic disease that is likely to explain the symptoms. Pathogenetic features include disturbed gastric accommodation and emptying, duodenal dysmotility, heightened sensitivity, notably psychosocial disturbances and an association with a postinfective state. Increasing efforts are made to determine the etiopathogenesis of the disease, including new molecular and genetic aspects. However, the exact etiopathologic mechanism that causes the symptoms in an individual patient remains to be identified. The new Rome III criteria redefine and sub-characterize FD patients according to their main symptoms and this can be of value for standardized research, development and control of new therapeutic strategies and calculated therapeutic recommendations in the clinical practice. Various treatment modalities have been employed including dietary modifications, pharmacological agents directed at different targets within the gastrointestinal tract and central nervous system and psychological therapies including hypnotherapy. Unfortunately, to date, all of these therapies have yielded only marginal results. After excluding organic diseases, it is essential that the patient be assured about the benign nature and prognosis of the disease, and this can be sometimes the most helpful inversion for the patient and his/her physician.

Encuesta piloto virtual a médicos argentinos (usuarios de la red intramed) sobre conocimientos, conductas diagnósticas y terapéuticas referidas a la dispepsia funcional / Virtual Pilot survey to Argentinian physicians (users from IntraMed), knowledge, diagnostic approach and therapeutic related to functional dyspepsia

La dispepsia funcional es una entidad muy frecuente en la práctica diaria tanto del gastroenterólogo como de médicos clínicos y aún de los que practican otras especialidades, pero continúa siendo muy polémica desde el punto de vista de su definición, clasificación, diagnóstico y su enfoque terapéutico. Para conocer el punto de vista y los conocimientos que los médicos argentinos tienen del tema hemos realizado una encuesta virtual. Objetivos: 1) Determinar creencias, criterios y conductas édicas diagnósticas y terapéuticas más frecuentes asociadas al cuadro clínico de dispepsia funcional. 2) Determinar (estimativamente) por los médicos que respondieron, la prevalencia de dispépticos en la consulta diaria y mensual. 3) Determinar (estimativamente) por los médicos que respondieron, la prevalencia de enfermedad orgánica dentro de los pacientes que consultaron por dispepsia funcional. Población y muestra: Médicos residentes en Argentina, usuarios de red virtual IntraMed (expuestos: n=12.849). Respondieron voluntariamente 622 médicos de las siguientes especialidades: generalistas, de familia, gastroenterólogos, erontólogos, cirujanos generales y “otras” (muestreo no probabilístico). Fueron excluidos 43 especialistas que respondieron por no constituir una especialidad que reciba este tipo de consultas con mayor frecuencia. Fueron eliminadas las respuestas de pediatras por ser de bajísima frecuencia (3 pediatras). Lugar y período de exposición a la encuesta: Buenos Aires, Red virtual IntraMed, desde enero de 2005 a enero de 2006, encuesta colgada on-line desde el 2 al 31 de mayo de 2005. Metodología: Invitación electrónica a participar luego de una breve difusión previa. Exhibición de la encuesta on-line durante mayo de 2005. Diseño: exploratorio, prospectivo, observacional, transversal, de cuantificación. Instrumento: Cuestionario que exploróentre médicos de diferentes especialidades de la Argentina: a) Dificultades y preferencias acerca de la definición...
