BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has increased in popularity in recent years as a definitive bariatric procedure. Despite its growing popularity worldwide, the surgical technique is not well standardized. There is a lack of evidence on the matter of the antrum size and its relation to gastric emptying and weight-loss outcomes. The aim of the study is to evaluate the influence of antrum size over gastric emptying and weight-loss outcomes. METHODS: Twenty-five patients were prospectively randomized according to the distance between the first firing and the pylorus: AR group (antrum resection-2 cm from the pylorus) and AP group (antrum preservation-5 cm from the pylorus)...

The rate of septum presence in the maxillary sinus has been reported to be over 30%. It was considered that a bony bridge might change to a maxillary sinus septum with growth in a previous study using dry child skulls. In the present investigation, maxillary sinus bony bridges and septa were longitudinally observed using computed tomography (CT). Multislice CT was performed in three patients. A bony bridge was defined as a bony structure between the maxillary sinus wall and dental germ. Also, a septum was defined as a pointed bony structure in the inferior wall of the maxillary sinus...

BACKGROUND: The treatment of severely injured patients in the trauma resuscitation unit (TRU) requires an interdisciplinary and highly professional trauma team approach. The complete team needs to be waiting for the patient in the TRU on arrival. Treating severely injured patients in the TRU, the trauma team connects the initial preclinical emergency stabilization with the subsequent sophisticated treatment. Thus, the trauma team depends on concise information from the emergency personnel at the scene to provide its leader with further information as well as an accurate alarm including all departments necessary to stabilize the patient in the TRU...

Recurrent unilateral pneumonia poses a diagnostic dilemma for all paediatricians. Isolated pulmonary venous atresia is an uncommon entity, which presents with recurrent unilateral pulmonary infections, dyspnoea on exertion and haemoptysis. It is associated with significant mortality and morbidity. Owing to rarity of condition, there may be some difficulties in the diagnosis and therapy. Pulmonary angiography is the investigation of choice. However, the current multislice CT scanners may obviate the need for pulmonary angiography...

Coronary artery calcification is a part of atherosclerosis process associated with coronary heart disease. Recently, coronary artery calcification assessment using computed tomography (CT) is still the best noninvasive imaging with high sensitivity and specificity. Osteoprotegerin (OPG) is one of vascular calcification marker that through its role to bind receptor activator of nuclear factor-κβ ligand and inhibit osteoclastogenesis is suspected of playing a role for coronary calcification in atherosclerosis process...
