Sialolithiasis is one of the most common and extensively obstructive disorders of the major salivary glands. Here, we report 3 cases of sialolithiasis in the submandibular salivary gland showing symptomatic similarities to other dental and non-dental disorders of the maxillofacial area. How the various clinical features of this condition and findings on 3D-CT may lead to a misdiagnosis are also discussed. In the first case, that of a 45-year-old woman, a final diagnosis of a non-radiopaque submandibular sialolith allowed the initially indicated surgical extraction of a malerupted and semi-impacted right mandibular 3rd molar to be abandoned...

Technicized medicine foreshadows a dehumanisation of care : patients are seen as tools for progress, and doctors are focused on the therapeutical means to be developed. Therefore, surgeons are torn between their desires, as technicians, to improve their tech-nical skills, and their duty, as doctors, to look after each patient who needs care. The advent of laparaoscopy has changed the way doctors consider their patients' bodies. The current state of surgery is in crisis insofar as humanist surgery can no longer meet the aspirations of modern surgery...

Nowadays, autograft and allograft techniques represent the main solution to improve bone repair. Unfortunately, autograft technique is expensive, invasive and subject to infections and hematoma, frequently affecting both donor sites and surgical sites. A recent advance in tissue engineering is the fabrication of cell-laden hydrogels with custom-made geometry, depending on the clinical case. The use of ECM (Extra-Cellular Matrix)-derived Hydrogels from bone tissue is the new opportunity to obtain good results in bone regeneration...

Intracranial electrophysiological recording in patients with refractory focal epilepsy is the gold standard for defining epileptogenic tissue. Although the concordance of intracranial electrophysiology, structural MRI, and pathology can identify brain regions for resection, complete seizure control after surgery is not achieved in all patients with focal epilepsy. Repetitive identical behavioural seizures suggest one onset area, but epileptogenesis might be distributed and connected by functional and structural brain networks outside the seizure onset area, which could explain poor postsurgical outcomes in some patients...

Histories of twentieth-century surgery have focused on surgical 'firsts' - dramatic tales of revolutionary procedures. The history of tonsillectomy is less glamorous, but more widespread, representing the experience and understanding of medicine for hundreds of children, parents and surgeons daily. At the start of the twentieth century, tonsillectomy was routine - performed on at least 80 000 schoolchildren each year in Britain. However, by the 1980s, public and professional discourse condemned the operation as a 'dangerous fad'...

Recent technological progress offers the opportunity to significantly transform conventional open surgical procedures in ways that allow minimally invasive surgery (MIS) to be accomplished by specific operative instruments' entry into the body through key-sized holes rather than large incisions. Although MIS offers an opportunity for less trauma and quicker recovery, thereby reducing length of hospital stay and attendant costs, the complex nature of this procedure makes it difficult to master, not least because of the limited work area and constricted degree of freedom...

Totally laparoscopic distal gastrostomy (TLDG) and laparoscopic- assisted distal gastrostomy (LADG) are the minimally invasive surgical technology for gastric cancer. This study aimed to compare the surgical outcomes of these two methods. Relevant studies were selected through electronic searches of EMBASE, PubMed and Web of Science. In total, 21 non-randomized controlled studies containing 2475 patients in the totally laparoscopic distal gastrostomy and 1889 patients in the laparoscopic-assisted distal gastrostomy were included in this study...

PURPOSE: The data which is available to surgeons before, during and after surgery is steadily increasing in quantity as well as diversity. When planning a patient's treatment, this large amount of information can be difficult to interpret. To aid in processing the information, new methods need to be found to present multimodal patient data, ideally combining textual, imagery, temporal and 3D data in a holistic and context-aware system. METHODS: We present an open-source framework which allows handling of patient data in a virtual reality (VR) environment...

Telemedicine, the remote diagnosis and treatment of patients by means of technology, provides an alternative means for patients to gain access to health care services. Telemedicine is a general term that includes the use of various communication technologies, including telephone, email, or videoconferencing. Telemedicine has the potential to reduce inefficiencies in the delivery of healthcare, diminish patient travel and wait times, and increase access to specialists for patients in rural settings. We review the use of telemedicine in the perioperative phase of care for pediatric surgical patients, their caregivers, and surgical providers, including pre-operative assessments, and post-operative follow-up...

Nowadays, bioactive glasses (BGs) are mainly used to improve and support the healing process of osseous defects deriving from traumatic events, tumor removal, congenital pathologies, implant revisions, or infections. In the past, several approaches have been proposed in the replacement of extensive bone defects, each one with its own advantages and drawbacks. As a result, the need for synthetic bone grafts is still a remarkable clinical challenge since more than 1 million bone-graft surgical operations are annually performed worldwide...

Belgium has been collaborating for 20 years with Abomey-Calavi University in Cotonou, Republic of Benin, to train anesthesiologists for Sub-Saharan, French-speaking African countries. With 123 graduates from 15 countries and 46 residents still in training, this program has succeeded in reversing the trend of a decreasing anesthesiology workforce in those countries, thus improving the quality of anesthesia and patient safety. Belgian government sources, as well as hospitals and anesthesia teams, provided most of the financial resources...

PURPOSE OF REVIEW: The past couple of decades have brought tremendous advances to the field of pediatric and adult congenital heart disease (CHD). Percutaneous valve interventions are now a cornerstone of not just the congenital cardiologist treating patients with congenital heart disease, but also-and numerically more importantly-for adult interventional cardiologists treating patients with acquired heart valve disease. Transcatheter pulmonary valve replacement (tPVR) is one of the most exciting recent developments in the treatment of CHD and has evolved to become an attractive alternative to surgery in patients with right ventricular outflow tract (RVOT) dysfunction...

Surgical simulators are being increasingly used as an attractive alternative to clinical training in addition to conventional animal models and human specimens. Typically, surgical simulation technology is designed for the purpose of teaching technical surgical skills (so-called task trainers). Simulator training in surgery is therefore in general limited to the individual training of the surgeon and disregards the participation of the rest of the surgical team. The objective of the project Assessment and Training of Medical Experts based on Objective Standards (ATMEOS) is to develop an immersive simulated operating room environment that enables the training and assessment of multidisciplinary surgical teams under various conditions...

OBJECTIVE: Radiation to the interventionalist's brain during fluoroscopically guided interventions (FGIs) may increase the incidence of cerebral neoplasms. Lead equivalent surgical caps claim to reduce radiation brain doses by 50% to 95%. We sought to determine the efficacy of the RADPAD (Worldwide Innovations & Technologies, Lenexa, Kan) No Brainer surgical cap (0.06 mm lead equivalent at 90 kVp) in reducing radiation dose to the surgeon's and trainee's head during FGIs and to a phantom to determine relative brain dose reductions...

BACKGROUND AND OBJECTIVE: While Minimally Invasive Surgery (MIS) offers considerable benefits to patients, it also imposes big challenges on a surgeon's performance due to well-known issues and restrictions associated with the field of view (FOV), hand-eye misalignment and disorientation, as well as the lack of stereoscopic depth perception in monocular endoscopy. Augmented Reality (AR) technology can help to overcome these limitations by augmenting the real scene with annotations, labels, tumour measurements or even a 3D reconstruction of anatomy structures at the target surgical locations...
