Aligners vs. Braces: Choosing the Right Treatment

In recent times, there have been notable strides in orthodontic treatments, presenting a multitude of choices for individuals seeking straighter teeth and a more appealing smile. To cater to the increasing demand for aesthetic alternatives to traditional braces, researchers have developed various options. These alternatives encompass ceramic or composite braces, lingual orthodontics, and transparent aligners. Among these alternatives, Invisalign aligners stand out as custom-made, transparent, and thin plastic aligners designed to gradually reposition teeth. This survey aims to evaluate disparities in the quality of life experienced by individuals undergoing treatment with clear aligners versus those receiving conventional orthodontic care

Coronary artery surgery: cardiotomy suction or cell salvage?

Coronary artery bypass grafting (CABG) today results in what may be regarded as acceptable levels of blood loss with many institutions avoiding allogeneic red cell transfusion in over 60% of their patients. The majority of cardiac surgeons employ cardiotomy suction to preserve autologous blood during on-pump coronary artery bypass surgery; however the use of cardiotomy suction is associated with a more pronounced systemic inflammatory response and a resulting coagulopathy as well as exacerbating the microembolic load. This leads to a tendency to increased blood loss, transfusion requirement and organ dysfunction. Conversely, the avoidance of cardiotomy suction in coronary artery bypass surgery is not associated with an increased transfusion requirement. There is therefore no indication for the routine use of cardiotomy suction in on-pump coronary artery surgery

Melanotic neuroectodermal tumor of infancy: Report of a case associated with high urinary excretion of Vanilmandelic acid

Melanotic neuroectodermal tumor of infancy is a rare congenital neoplasm involving the head and neck region in young patients. A case of melanotic neuroectodermal tumor of infancy is presented. This tumor occurred in right maxillary alveolar ridge in a 4-month-old infant. The present case showed an increased urinary level of vanilmandelic acid, confirming that the tumor is originated from neural crest. Clinical assessment, histologic diagnosis, and laboratory findings supported the diagnosis
