primary leiomyosarcoma of the broad ligament is a very rare, rapidly progressive and highly malignant gynecological tumor and only 16 cases have been reported in the literature. here, presentation of leiomyosarcoma of the left broad ligament in a 26-years-old woman is reported. clinical presentation and histological diagnosis is discussed. the patient has been treated surgically and remains dis...

Background Superior capsule reconstruction (SCR) has been developed to improve shoulder function and relieve pain in the treatment of irreparable rotator cuff tears. Previous studies have reported that graft healing can enhance favorable outcomes after SCR. On other hand, tears often lead less desirable sometimes require additional surgical procedures. However, process underlying this ...

BACKGROUND Intra-abdominal lymphangiomas are rare, benign tumors in adults. This report is the third documented case of a lymphangioma originating in the hepatoduodenal ligament that mimicked a simple liver cyst. CASE PRESENTATION A 50-year-old woman was admitted with a cystic tumor in the right lobe of her liver and underwent laparoscopic excision of the cyst. Operative findings revealed tha...

Patellar desmopathy in dogs after tibial plateau levelling osteotomy has been described in many studies. Tibial tuberosity advancement is a biomechanically different technique. It is assumed that the patellar ligament is loaded with little force similarly as after tibial plateau levelling osteotomy. Various aspects related to secondary patellar desmopathy are not completely understood. This stu...

This paper proposes a global learning of neural networks by hybrid optimization algorithm. The hybrid algorithm combines a stochastic approximation with a gradient descent. The stochastic approximation is first applied for estimating an approximation point inclined toward a global escaping from a local minimum, and then the backpropagation(BP) algorithm is applied for high-speed convergence as ...

OBJECTIVE Radical hysterectomy with pelvic lymphadenectomy is the treatment of choice for early-stage cervical cancer. Wertheim's original technique has been often modified, mainly in the extent of parametrectomy. Okabayashi's technique is considered as the most radical variant regarding removal of the ventral parametrium and paracolpal tissues. Surgical outcome concerning recurrence and surviv...

BACKGROUND Tibial fixation of hamstring tendon grafts has been the weak link in anterior cruciate ligament reconstruction. HYPOTHESIS Use of a central four-quadrant sleeve and screw provides superior fixation when compared with standard interference screw fixation. STUDY DESIGN Controlled laboratory study. METHODS In eight pairs of cadaveric knees each anterior cruciate ligament was recon...

OBJECTIVE This study had the objective of prospectively comparing transverse fixation (Cross-Pin™) with extracortical fixation (EZLoc™) for the femur, in surgical reconstruction of the anterior cruciate ligament, from a clinical, biomechanical and functional point of view. METHODS Between April 2007 and November 2009, 50 patients with acute or chronic anterior cruciate ligament injuries under...
