Background Eosinophilic myocarditis is a rare clinical entity characterized by eosinophilia and myocardial inflammation with infiltrating eosinophils. The prognosis of patients with eosinophilic myocarditis is difficult to determine due the disease's rarity and varied causes; consequently, standard treatment has not been established.
Situs solitus refers to the normal arrangement of body organs. Situs inversus totalis is a complete mirror image or reverse isomeric form of the thoracic and abdominal viscera. Any arrangement of organs between these two extremes is designated by heterotaxia. Several patterns of vascular and visceral abnormalities are associated with heterotaxia, and two loosely defined syndromes of splenic anomalies (asplenia and polysplenia) are most common. We present the case of a 71-year-old woman with situs inversus totalis and polysplenia syndrome who developed synchronous double cancer originating from the stomach and rectum. Abdominal manifestations were situs inversus totalis combined with multiple lobulated spleen, azygous continuation of the interrupted inferior vena cava, direct drainage of hepatic vein to left atrium, preduodenal portal vein, short pancreas, incomplete rotation of the colon, and malrotation of the intestine. Histologically, gastric cancer was diagnosed as papillary adenocarcinoma and rectal cancer, as moderately differentiated adenocarcinoma. The patient was successfully treated with total gastrectomy for gastric cancer and low-anterior resection of the rectum for rectal cancer.
PurposeThe purpose of this study was to assess the differences in bone tunnel apertures between the trans-accessory medial portal (trans-AMP) technique and the transtibial (TT) technique in double-bundle anterior cruciate ligament reconstruction. The extent of ovalization and the frequency of overlap of the two tunnel apertures were compared.MethodsThe simulation of femoral tunnel drilling with the TT and the trans-AMP techniques was performed using three-dimensional computer aided design models from two volunteers. The incidence angle of drilling against the intercondylar wall, the femoral tunnel position, the ovalization, and the overlap were analyzed. The aperture and location of the tunnels were also examined in real anterior cruciate ligament reconstruction cases (n=36).ResultsThe surgical simulation showed that a lower drill incident angle induced by the TT technique made the apertures of two tunnels more ovalized, located anteromedial tunnels in a shallower position to prevent posterior wall blow out, and led to a higher frequency of tunnel overlap. The trans-AMP group had tunnel places within the footprint and had less ovalization and overlap. The results of analysis for tunnels in the clinical cases were consistent with results from the surgical simulation.ConclusionIn the TT technique, the shallow anteromedial tunnel location and more ovalized tunnel aperture can lead to a higher frequency of tunnel overlap. Compared with the TT technique, the trans-AMP technique was more useful in preparing femoral tunnels anatomically and avoiding tunnel ovalization and overlapping in double-bundle anterior cruciate ligament reconstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
