BACKGROUND: The distance between the anterior wall of the maxillary sinus and the nasolacrimal duct shows a large individual variation. METHODOLOGY: To evaluate the feasibility of accessing the maxillary sinus through a prelacrimal window access (PLWA), a series of 100 paranasal CT scans from adult patients was analysed retrospectively. The distance between the anterior maxillary wall and the anterior border of the lacrimal duct (= prelacrimal window) were measured in 200 sides...

BACKGROUND: Epidemiological studies of acetabular fractures (AFs) are scarce and, to our knowledge, the most recent one from France,by Letournel and Judet,dates back to 1993. Studies have suggested a decrease in high-energy AFs contrasting with an increase in low-energy AFs due to the longer life expectancy. However, a French case-series study failed to confirm these data. We therefore conducted a 10-year retrospective study in a Level-1 trauma centre to: 1) characterise the epidemiological profile of AF, 2) and to describe the treatment strategy...

An animal model that allows for assessment of the degree of stretching or contraction of the implant area and the in vivo degradation properties of biological meshes is required to evaluate their performance in vivo. Adult New Zealand rabbits underwent full thickness subtotal unilateral rectus abdominis muscle excision and were reconstructed with the non-biodegradable Peri-Guard(®), Prolene(®) or biodegradable Surgisis(®) meshes. Following 8 weeks of recovery, the anterior abdominal wall tissue samples were collected for measurement of the implant dimensions...

Immunoglobulin G4 (IgG4)-related sclerosing disease is a recently proposed systemic fibroinflammatory disease entity, with periaortitis as a representative manifestation in the cardiovascular system. We present a case of IgG4-related periaortitis involving the aortic arch and proximal great vessels, mimicking an anterior mediastinal tumor on computed tomography. In patients with a soft tissue mass along the aortic wall, IgG4-related periaortitis should be included as a differential diagnosis and timely serologic investigation should be performed to prevent unnecessary surgery, because the disease shows a remarkable response to corticosteroids...

INTRODUCTION: The incidence of geriatric acetabular fractures continues to increase due to demographic changes. In the elderly, anterior column fractures are common, and standard approaches are associated with a considerable risk for surgery-associated complications. Therefore, a minimally invasive approach was developed in our department. The aim of this study was to examine early and mid-term results regarding the use of this novel two-incision minimally invasive (TIMI) approach in patients aged over 55 years with acetabular fractures...

The technique for successful surgical correction of an anomalous origin of the right coronary artery from the opposite aortic cusp with an aberrant course between the aorta and pulmonary artery is illustrated in a symptomatic 62-year-old woman. The intramural course of the right coronary artery traversed the tip of the commissure between the anterior and posterior leaflets, and its repair entailed unroofing of the intramural segment from inside the aortic intima. This technique required resuspension of the overlying commissure to maintain optimal aortic valve leaflet coaptation and prevent aortic insufficiency...

The less traumatic use of surgical adhesives rather than sutures for mesh fixation in hernia repair has started to gain popularity because they induce less host tissue damage and provoke less postoperative pain. This study examines the host tissue response to a new cyanoacrylate (CA) adhesive (n-octyl, OCA). Partial defects (3 × 5 cm) created in the rabbit anterior abdominal wall were repaired by mesh fixation using OCA, Glubran2(®)(n-butyl-CA), Ifabond(®)(n-hexyl-CA) or sutures. Samples were obtained at 14/90 days for morphology, collagens qRT-PCR/immunofluorescence and biomechanical studies...

A 36-year-old woman was seen with complaints of exertional chest pain and shortness of breath. Her medical history included atrial fibrillation and diabetes. Physical examination was unremarkable except for an irregular cardiac rhythm. Myocardial perfusion imaging revealed the presence of a large area of infarction involving the entire anterior and apical walls and part of the anteroseptal wall with minimal periinfarct ischemia. Computed tomography coronary angiogram revealed an anomalous left main coronary artery arising from the main pulmonary artery...

Desmoid tumors are fibroblastic connective tissue tumors that most commonly develop within the anterior abdominal wall. The etiology of desmoid tumors has not been well defined; however, hereditary, hormonal, traumatic, and surgery-related causes have been implicated. Desmoid tumors are believed to arise from musculoaponeurotic structures. Development in the breast is very rare. Several reports of desmoid tumors arising in the vicinity of the fibrous capsule of a breast implant have been described, but to date, the authors are not aware of any published cases following autologous breast reconstruction...

BACKGROUND AND PURPOSE: Cerebral aneurysms in the posterior circulation are known to have a higher rupture risk than those in the anterior circulation. We sought to test the hypothesis that differences in hemodynamics can explain the difference in rupture rates. MATERIALS AND METHODS: A total of 117 aneurysms, 63 at the tip of the basilar artery (27 ruptured, 36 unruptured, rupture rate = 43%) and 54 at the bifurcation of the internal carotid artery (11 ruptured, 43 unruptured, rupture rate = 20%) were analyzed with image-based computational fluid dynamics...

PURPOSE: Maxillofacial injuries are frequently associated with multiple trauma and can determine functional and aesthetic bad outcomes. The severity of maxillofacial injuries may be considerable and can divert clinicians' attention from other concomitant injuries which is less evident but potentially life-threatening. The aim of this study was to find out the concomitant injuries in patients referred to the Emergency Department (ED) of the University Hospital of Messina (North-East Sicily, Italy) for maxillofacial traumas...

Temporal lobe epilepsy often propagates inter-hemispherically. Although the pathway of the propagation was verified by electrophysiology, the trajectory remains poorly defined. DTI can depict fiber trajectory but it has limited angular resolution and cannot adequately assess cortical regions. We visualized potential pathways of bitemporal epilepsy propagation using diffusion spectrum imaging (DSI) with data consisting of 8 groups of 514 directions and diffusion templates of 842 subjects from the human connectome project (HCP)...

BACKGROUND: Positive T wave in lead aVR has been shown to predict an adverse in-hospital outcome in patients with anterior wall ST-segment elevation myocardial infarction (STEMI). However, the prognostic value of positive T wave in lead aVR on a long-term outcome has not been fully explored. METHODS: We performed a retrospective analysis of 190 consecutive patients with first anterior wall STEMI who underwent an emergent coronary angiogram. Patients were divided into those with positive T wave > 0 mV and those with negative T wave ≦ 0 mV in lead aVR...

The use of energy drinks, which often contain stimulants, is common among young persons, yet there have been few reports of adverse cardiac events. We report the case of a 27-year-old man who was admitted to our facility with an acute ST-segment elevation myocardial infarction in the setting of using energy drinks. Angiography revealed no obstructive coronary disease. The patient had elevation of cardiac troponin. Noninvasive testing with echocardiography and cardiac magnetic resonance imaging demonstrated both abnormalities in resting wall motion at the anterior apex along with late gadolinium enhancement of the anterior wall, respectively...
