ABSTRACT
Resumen La anisakidosis es una zoonosis parasitaria accidental y cosmopolita de los seres humanos, siendo su hospedero definitivo los mamíferos marinos como lobos de mar, focas y delfines, entre otros. El ser humano se infecta por el consumo en estado larvario del nemátodo de la familia Anisakidae presentes en pescados y mariscos crudos como la merluza o el congrio. Los helmintos se ubican preferentemente en el tubo digestivo alto, observándose la regurgitación del parásito a la boca o evidenciándose durante la realización de una endoscopía digestiva alta. En forma infrecuente las larvas pueden migrar al peritoneo o seguir su paso por el intestino delgado y colon, siendo inhabitual la expulsión por las deposiciones. Presentamos el caso de una expulsión dos larvas L3 de la familia Anisakidae en deposiciones.
Abstract Anisakidosis is an accidental and cosmopolitan parasitic zoonosis of human beings, its definitive host being marine mammals such as sea lions, seals and dolphins, among others. Humans are infested by consumption in the larval stage of the nematode of Anisakis present in raw fish and shellfish such as hake or conger eel. The infestation is preferably located in the upper digestive tract, observing the regurgitation of the parasite to the mouth or becoming evident during an upper gastrointestinal endoscopy. In rare cases, the larvae can migrate to the peritoneum or continue their passage through the small intestine and colon, with expulsion in stools being unusual. We present a case of expulsion of two larvae of the Anisakidae family in feces.

Osteosarcopenia is defined as the concomitant occurrence of osteoporosis and sarcopenia. Current lack of consensus on sarcopenia definitions, combined with the low sensitivity and specificity of screening methodologies, has resulted in varying prevalences of sarcopenia, and consequently osteosarcopenia diagnosis. Previous research indicates that mid-thigh is a potential surrogate region for the assessment of bone, muscle, and fat mass in a single, efficient and low-radiation dual x-ray absorptiometry (DXA) scan. We hypothesized that muscle and bone mass measurements in the mid-thigh region can be used to evaluate bone and muscle health and function. A retrospective study was conducted on community-dwelling older subjects (> 65 y.o., n = 260) who were at risk of falls and fractures. Mid-thigh and mid-calf bone, lean muscle, and fat masses, as well as their association with muscle function, falls, and fractures were compared against conventional measures (hip/spine bone, appendicular lean, and gynoid/android fat masses). Mid-thigh bone, lean, and fat masses showed strong correlation with conventional measures. Mid-thigh lean mass showed similar associations with grip strength, gait speed, and timed up and go (TUG) test as appendicular lean mass. Appendicular, mid-thigh and mid-calf lean masses corrected for body mass index (BMI) showed stronger associations than when corrected for height2. None of the indices were associated with fractures; but fat mass was invariably associated with falls. Those with falls and fractures history had lower bone and muscle mass at mid-thigh. Mid-thigh is a potential new surrogate to study bone, muscle, and fat mass in older people, with comparable ability in predicting muscle performance and falls.
