In this paper we prove that one can find surgeries arbitrarily close to infinity in the Dehn surgery space of the figure eight knot complement for which some immersed totally geodesic surface compresses. MSC: 57M25, 57M50

BACKGROUND The complexity of surgical interventions has major implications for the design of RCTs. Trials need to consider how and whether to standardize interventions so that, if successful, they can be implemented in practice. Although guidance exists for standardizing non-pharmaceutical interventions in RCTs, their application to surgery is unclear. This study reports new methods for standar...

Academic research a prerequisite for patient safety in surgery In the past experimental and clinical research efforts in surgery have been considered the “golden key” for understanding the underlying pathomechanisms of surgical diseases, for successful development of surgical techniques, improved patients quality of life and beneficial clinical outcome. Furthermore, scientific findings and evid...

BACKGROUND Surgical site infection rates are of great interest to patients, surgeons, hospitals and third-party payers. While previous studies have reported hospital-acquired infection rates that are nonspecific to all surgical services, there remain no overall reported infection rates focusing specifically on plastic surgery in the literature. OBJECTIVE To estimate the reported surgical site...

The usefulness of sonotopogram, that is mapping of the operated area basing on ultrasound, is obvious and currently unquestionable. It is performed in order to improve safety level of a patient treated by means of invasive techniques. It constitutes an excellent complement of the Perioperative Control Card. At the beginning it was used in sonosurgical procedures, with time it has become an elem...

receive prophylactic antibiotics, primarily for surgical procedures. Although early studies in the 1950s and 1960s concluded that prophylaxis was not helpful, many of these studies were poorly done, and the basic principles of appropriate prophylactic antibiotic use were not understood. In reality, patients often were given therapeutic antibiotics; that is, the infection had already occurred. S...

Evidence-based Dentistry (EBD), like Evidence-based Medicine (EBM), was born in order to seek the "best available research evidence" in the field of dentistry both in research and clinical routine.BUT EVIDENCE IS NOT CLEARLY MEASURABLE IN ALL FIELDS OF HEALTHCARE: in particular, while drug effect is rather independent from clinician's characteristics, the effectiveness of surgical procedures is...
