Coca leaf has been traditionally used for medical purposes and contains high iron levels. Objective: To determine the effect of Erythroxylum coca spp. ethanol extract in iron-deficiency anemia induced by iron-deficient diet in male Holtzman rats. Design: Experimental. Setting: Institute of Pathology Laboratory, Universidad Nacional Mayor de San Marcos. Biologic material: Eighteen weaned male Holtzman rats 16 days old. Interventions: Rats were allocated to three groups of six rats each: a) iron-sufficient group (IS) received 25 g/d of balanced diet for 7 weeks; b) iron-deficient group (ID) received 25 g/d of iron-deficient diet for 7 weeks; and, c) irondeficient/ E. coca extract group (ID-CE) received 25 g/d of iron-deficient diet for 7 weeks, and in the fifth week 18 g/d of E. coca extract were added. Main outcome measures: Serum hemoglobin level, weight and height. Results: At the end o...

A 15-year-old male patient presented with dysphagia, regurgitation, weight loss and retrosternal pain. The diagnosis of achalasia was made 4 years before. The esophagogram revealed severe esophagus dilatation and the classic “bird-beak” termination. A Heller myotomy plus fundoplication and endoscopic balloon dilatation were conducted four months previously. Nevertheless, the symptoms persisted and the last high-resolution manometry study still showed achalasia type II. The patient underwent a peroral endoscopic esophageal myotomy (POEM). POEM is a feasible and safe procedure for experienced and properly- equipped health care delivery centers and could be used as a rescue treatment in refr e present the youngest patient with achalasia in our region who had a successful response to rescue POEM.
