Rotational malalignment complication following TKA, is common but can be avoided with proper surgical technique. This paper reviews the literature regarding rotational alignment during TKA, femoral and tibial rotation, and highlights the techniques prior in obtaining proper rotational positioning, nevertheless correct positioning in all three planes is important. Proper femoral component positioning in the axial plane is done using as landmarks the posterior condylar line (PCL), surgical transepicondylar axis (sTEA), anatomical transepicondylar axis and the trochlear anteroposterior (AP) axis. The paper describes the angular relationships between these landmarks and the distal femur. Axial tibial positioning is done when using intraarticular landmarks, the combination of more than one landmark could be a solution for solving this problem. The consensus is that femoral component should be positioned according to TEA but the interobserver variability of this land mark is very high. The rotation of the tibial component remains an open subject, most studies suggesting a point between half of the distance of patellar ligament and 1/3 of the internal tuberosity as optimal landmark.
Background and aim: Minimally invasive surgery represents the actual tendency in many medical domains including urology. Gaining practical skills for these procedures becomes essential when preparing the future resident physicians in urology. The purpose of this study is to demonstrate that using medical simulation as an education tool improves the practical skills of the urology house officers in laparoscopy by using an accessible tool such as a box trainer. Methods: The study includes the objective and subjective evaluation of the practical skills of 54 students with no experience in laparoscopy. Each participant was evaluated before doing the practical activity on the simulator both in a subjective manner by filling a self-evaluation form and also objectively by timing the duration of doing laparoscopic basic tasks, knot tying and realizing a continuous suture. The participants were divided in two groups (A-28 participants, B-26 participants). Each group executed the same procedures with the same instruments, but with a different teaching technique. Results and conclusions: Medical education with the help of a laparoscopic box trainer simulator is a useful tool for improving practical abilities and the time of execution of general procedures.
Several problems related to coagulation dysfunctions induced by selective serotonin reuptake inhibitors (SSRIs) were reported in literature, as serotonin is widely distributed in the human organism and it has significant contribution in various vascular and hematologic regulatory mechanisms. First, a systematic review has integrated main results from the field of SSRIs and anticoagulants pharmacologic interactions. Secondly, a retrospective analysis was performed, based on the medical charts of hospitalized patients diagnosed with SSRI-treated depressive disorders, who also received concomitant anticoagulant treatment with acenocoumarol. Platelet count, prothrombin time, activated partial thromboplastin time, and bleeding time were monitored during hospitalization and their values before and after SSRI initiation treatment were compared.
