[Laparoscopic splenectomy due to torsion of a wandering spleen]. / Esplenectomía laparoscópica por torsión de un bazo ectópico (wandering spleen).

Wandering spleen is an uncommon entity, characterized by the anomalous position of the spleen, caused by the absence or laxity of its suspensory ligaments. The most common symptoms are usually due to intermittent or complete torsion of the splenic pedicle with subsequent infarction. We report a case of torsion of a wandering spleen. Laparoscopic splenectomy was performed and recovery was uneventful. Although few cases of wandering spleen treated laparoscopically have been reported in the literature, laparoscopy has been demonstrated to be a safe technique for the treatment of this entity.

Esplenectomía laparoscópica por torsión de un bazo ectópico (wandering spleen) / Laparocopic splenectomy due to torsion of a wandering spleen

El bazo ectópico o errante (wandering spleen) es una anomalía muy infrecuente caracterizada por una mala posición del bazo como consecuencia de una ausencia o laxitud de los ligamentos suspensorios del bazo. Las manifestaciones clínicas suelen producirse por una torsión completa o intermitente del pedículo esplénico, con el consiguiente riesgo de isquemia del bazo. Presentamos un caso de bazo ectópico con torsión del pedículo, tratado mediante esplenectomía laparoscópica sin complicaciones. Aunque hay pocos casos comunicados en la literatura científica, la laparoscopia ha demostrado ser una técnica válida y segura en el tratamiento del bazo ectópico (AU)

Effects of extrusion, boiling, autoclaving, and microwave heating on lupine allergenicity.

Lupine flour has been reported as a causative agent of allergic reactions. However, the allergenicity of lupine after thermal processing is not well-known. For this purpose, the allergenic characteristics of lupine seeds after boiling (up to 60 min), autoclaving (121 degrees C, 1.18 atm, up to 20 min and 138 degrees C, 2.56 atm, up to 30 min), microwave heating (30 min), and extrusion cooking were studied. The IgE-binding capacity was analyzed by IgE-immunoblotting and CAP inhibition using a serum pool from 23 patients with lupine-specific IgE. Skin testing was carried out in four patients. An important reduction in allergenicity after autoclaving at 138 degrees C for 20 min was observed. IgE antibodies from two individual sera recognized bands at 23 and 29 kDa in autoclaved samples at 138 degrees C for 20 min. Autoclaving for 30 min abolished the IgE binding to these two components. A previously undetected band at 70 kDa was recognized by an individual serum. Therefore, prolonged autoclaving might have an important effect on the allergenicity of lupine with the majority of patients lacking IgE reactivity to these processed samples.
