ABSTRACT
Ruptures of extensor pollicis longus (EPL) tendon may need a tendon transfer for repair, especially in chronic ruptures. We describe a novel transfer technique using a loop-tendon suture for dynamic transfer of extensor pollicis brevis to EPL. We performed an end-to-side transfixing-loop self-locking suture preserving the extensor pollicis brevis, which acts as a motor unit for the distal end of the repaired tendon. Contraindications would mainly be simultaneous rupture of EPL and brevis tendons. No complications were observed, except for mild metacarpal-phalangeal stiffness in chronic ruptures. An early rehabilitation program may be started when no other associated injuries exist.

The frequency of trichinosis was determined in 300 dead persons, residents in the provinces of Concepción and Arauco, and requiring necropsy at the Servicio Medico Legal of Concepción. Diaphragm muscle samples were taken from june 1996 to march 1997. The diagnosis was made by trichinoscopy and artificial digestion techniques. Five samples (1.67 percent) were positive. There was not differences between sexes. Positive cases were found mainly among 30 to 49 years old people belonging to middle-lower class. Both diagnostic techniques showed diferent sensitivity as a consequence of the parasitic load and on the contrary, the artificial digestion was less sensitiva when the cyts were fully calcified

Se describe el hallazgo de Cyclospora cayetanensis en una muestra de deposición, en la cual se observó también formas vacuoladas de Blastocystis hominis y trofozoítos y quistes de Entamoeba coli. La muestra provenía de un paciente de 50 años de edad, de sexo femenino, quien había visitado Cuba, y que, a los 5 días de regreso a Chile, comenzó con sintomatología. El examen parasitológico seriado de deposición se llevó al cabo 30 días después de su regreso al país. Se realizó observación al fresco de heces preservadas en fijador PAF (fenol, alcohol, formalina) con lugol, MIF (merthiolate, lugol, formol), y yodo de D'Antoni; al mismo tiempo se prepararon 3 frotis de sedimento fecal los que fueron teñidos mediante tinción de Ziehl Neeisen modificada, Kinyou y Safranina. Una proporción de los ooquistes encontrados fueron medidos. La identificación de C. cayetanensis fue confirmada en esta muestra por el Center for Disease Control and Prevention (CDC Atianta, Georgia, USA) y por el Departamento de Parasitología del Hospital for Tropical Diseases (London UK). Este constituye el primer hallazgo de C. cayetanensis informado en Concepción, Chile
