During transvaginal USLS, performance of a concomitant anterior colporrhaphy increased the risk of ureteral occlusion, while the use of a suture-capturing device for suspension suture placement was associated with decreased risk.

This study aims to develop the first Latin-American risk model that can be used as a simple, pocket-card graphic score at bedside. The risk model was developed on 2903 patients who underwent cardiac surgery at the Spanish Hospital of Buenos Aires, Argentina, between June 1994 and December 1999. Internal validation was performed on 708 patients between January 2000 and June 2001 at the same center. External validation was performed on 1087 patients between February 2000 and January 2007 at three other centers in Argentina. In the development dataset the area under receiver operating characteristics (ROC) curve was 0.73 and the Hosmer-Lemeshow (HL) test was P=0.88. In the internal validation ROC curve was 0.77. In the external validation ROC curve was 0.81, but imperfect calibration was detected because the observed in-hospital mortality (3.96%) was significantly lower than the development dataset (8.20%) (P<0.0001). Recalibration was done in 2007, showing excellent level of agreement between the observed and predicted mortality rates on all patients (P=0.92). This is the first risk model for cardiac surgery developed in a population of Latin-America with both internal and external validation. A simple graphic pocket-card score allows an easy bedside application with acceptable statistic precision.

A 63 year-old man had a past medical history of diabetes and hypertension, did not smoke or drink alcohol, and had no relevant family history. Over the course of several months he developed left leg weakness and difficulty climbing stairs. He denied other symptoms including fever, sweats, chills, shortness of breath or chest pain. On general examination he had no adenopathy or hepatosplenomegaly. Neurological examination revealed focal weakness of the left hip flexor but was otherwise normal. Electromyography (EMG) showed a myopathic process. A biopsy was performed on an unspecified leg muscle.
