This paper proposes a soft target discriminative learning method for posterior pseudo-probabilities based classification. The empirical loss is measured based on two soft targets which are corresponding with positive samples and negative samples of the class. The learning objective is to minimize empirical loss and maximize the difference between two soft targets. Consequently, we obtain unknow...

Diverticula of the left atrium are very rare malformations of unknown etiology and may be associated with arrhythmias, thromboembolism, or mitral valve regurgitation. We report a patient with suspected coronary artery disease (CAD) in whom we performed a low-dose computed tomography coronary angiography using prospective electrocardiogram triggering. CAD could be ruled out. Incidentally, we fou...

abstract traumatic hip dislocations are common in high-energy motor vehicle accidents. we present a case of a 43-year old man who sustained posterior hip dislocation with posterior wall acetabular fracture and ipsilateral intertrochantric fracture following a motorcycle accident. urgent open reduction and internal fixation of the hip fracture-dislocation and fixation of intertrochantric fractur...

Vaginal wall cysts occur rarely and can cause a variety of symptoms. A 35 year old woman presented with history of mass bulging from vagina for a year. Pelvic examination revealed a reducible non-tender mass protruding from the vagina and diagnosed as rectocele. Physical examination is important for the detection and characterization of vaginal cysts but may be inadequate for appropriate diagno...

Acute posterior wall myocardial infarction (PMI) occurs in up to 20% of cases of acute myocardial infarction (MI), with the vast majority occurring along with inferior or lateral acute MI.1 A true PMI is considered more rare, with an incidence of approximately 3.3%.2 The term PMI is used for necrosis of the part of the left ventricle located beneath the atrioventricular sulcus.3 The majority of...

Introduction Primary goal in surgical management of chronic otitis media with cholesteatoma is the creation of a dry, safe ear through removal of disease and prevention of recurrence. Canal wall up (CWU) techniques preserve the anatomy of the posterior canal wall, eliminating the need for periodic bowl cleaning and avoiding the risk of recurrent bowl infections. However, the recurrence rate may...
