Use of racecadotril as outpatient treatment for acute gastroenteritis: a prospective, randomized, parallel study.

OBJECTIVE: To compare the efficacy of therapy with racecadotril plus oral rehydration versus oral rehydration alone in children with gastroenteritis in an outpatient setting care. STUDY DESIGN: Prospective, randomized, open and parallel study performed in a Pediatric Emergency Service of a tertiary care hospital. The study included 189 patients, ages 3 to 36 months, with acute gastroenteritis: 94 were administered an oral rehydration solution (OR), 94 received oral rehydration solution plus racecadotril (OR + R). The principal variable studied was the number of bowel movements in 48 hours after initiating treatment. RESULTS: The groups were comparable clinically and epidemiologically at enrollment. No significant differences were found in the number of bowel movements between the 2 groups 48 hours after initiating treatment (4.1 +/- 2.7 bowel movements in the OR group vs 3.8 +/- 2.4 bowel movements in the OR + R group). No differences were found in the average duration of gastroenteritis (4.7 +/- 2.2 days in the OR group, 4.0 +/- 2.1 days in the OR + R group; P = .15). The incidence of adverse events was similar in both groups (19 patients [20.2%] in the OR group, 18 patients [19.1%] in the OR + R group). CONCLUSIONS: In our study group, the use of racecadotril did not improve the symptoms of diarrhea compared with standard rehydration therapy.

Hallazgo incidental de timoma paracardiaco derecho en enferma con infarto del miocardio / Incidental finding of a right paracardiac thymoma in a woman with a myocardial infarction

Los timomas son tumores primarios que provienen de células epiteliales del timo. Es frecuente encontrarlos en el mediastino anterior y asociados a un síndrome paratímico. Aunque pueden ser asintomáticos, es posible que cursen con manifestaciones clínicas inespecíficas como dolor precordial, disnea y tos, que habitualmente desaparecen con la extirpación quirúrgica. En estas condiciones, el diagnóstico es incidental y habitualmente se establece por varios métodos de imagen como la radiografía de tórax, tomografía axial computada o la resonancia magnética, y se confirma por biopsia tumoral. La sobrevida depende del estadio clínico de Masaoka, tamaño tumoral, tipo de resección y el subtipo histológico. La extirpación quirúrgica completa es el objetivo principal. El uso de quimioterapia y/o radioterapia pre y/o posquirúrgica es aún controversial. Presentamos el caso clínico de una mujer quien, después de sufrir un infarto al miocardio, durante su estudio se encontró de manera incidental una masa paracardiaca derecha que correspondió a un timoma.

Thymomas are primary tumors that arise from the epithelial cells of the thymus. Frequently, they are found in the anterior mediastinum, associated to a parathymic syndrome. Although they may stay asymptomatic, they may also give rise to unspecific clinical manifestations, which include chest pain, dyspnea, and cough, symptoms that generally disappear with surgical resection of the thy moma. In these cases, incidental diagnosis is usually established by using various image methods that may include chest X-ray, computed tomography, and magnetic resonance, and it is confirmed by tumor biopsy. Survival depends on Masaoka's clinical stage, the size of the tumor, the type of resection performed and the histológical subtype. Complete surgical resection is the main objective. The use of pre and/or postoperatory chemo and/or radiotherapy is still controversial. We present the case of a woman who suffered from a myocardial infarction. She was later incidentally diagnosed with a right paracardiac tumor that came out to be a thymoma.
