BACKGROUND: Intra-operative quantification of the ossicle mobility could provide valuable feedback for the current status of the patient's conductive hearing. However, current methods for evaluation of middle ear mobility are mostly limited to the surgeon's subjective impression through manual palpation of the ossicles. This study investigates how middle ear transfer function is affected by stapes quasi-static stiffness of the ossicular chain. The stiffness of the middle ear is induced by a) using a novel fiber-optic 3-axis force sensor to quantify the quasi-static stiffness of the middle ear, and b) by artificial reduction of stapes mobility due to drying of the middle ear...

The enthesis, or interface between bone and soft tissues such as ligament and tendon, is prone to injury and often does not heal post-surgical intervention. Interface tissue engineering represents an integrative strategy for regenerating the native enthesis by functionally connecting soft and hard tissues and thereby improving clinical outcome. This review focuses on integrative and cell-instructive scaffold designs that target the healing of the two most commonly injured soft tissue-bone junctions: the tendon-bone interface (e...

We report the case of a patient with severe mitral regurgitation who was diagnosed with double-orifice mitral valve by preoperative transthoracic and transoesophageal echocardiography. During surgery, it was revealed that the mitral valve was divided into 2 orifices, anterolateral and posteromedial, by a fibrous bridging tissue that was supported by the chordae tendineae originating from an accessory middle papillary muscle. The posterior scallop of the anterolateral orifice was prolapsed due to chordal elongation...

The restoration of single discolored maxillary anterior teeth is still a difficult task, as not only shape and surface characterization play an important role in the success of the treatment, but the propagation of light throughout the restorative material does as well. In some cases, small changes in morphology, color, and brightness will be noticeable. These factors are sometimes very tricky, and shade guides alone are difficult to use for color selection. This article proposes a protocol of employing cross-polarization imaging for improving the accuracy of the shade selection of resin composites...

We describe a 63 year old Romanian female patient admitted to our institution with complaints of typical angina and a diagnosis of non ST-elevation myocardial infarction. Coronary arteriography unveiled anomalous origin of a left circumflex coronary artery from the right coronary sinus of Valsalva near the right coronary ostium and a hyperdominant left anterior descending coronary artery giving off a posterior descending coronary artery with small distal-posterolateral left ventricular branch. The co-existence of a left circumflex coronary artery originating ectopically from the right sinus of Valsalva together with a posterior descending coronary artery originating from the distal end of the anterior descending artery is important to keep in mind especially by those doing coronary angiography in the cardiac catheterization laboratory...

Anterior segment ischemia (ASI) is a potentially serious but rare complication of strabismus surgery. Among several risk factors, ASI occurs after strabismus surgery because of the nature of the anterior segment circulation. Disinsertion of rectus muscles leads to a decrease in the blood supply to the various anterior segment structures. We report a series of retrospective and prospective studies performed by our group focused on determining the risk of anterior segment ischemia following strabismus surgery, diagnosis, and modifications to surgical techniques to minimize the impact on anterior segment circulation...

Assessment of global endocranial morphology and regional neuroanatomical changes in early hominins is critical for the reconstruction of evolutionary trajectories of cerebral regions in the human lineage. Early evidence of cortical reorganization in specific local areas (e.g. visual cortex, inferior frontal gyrus) is perceptible in the non-human South African hominin fossil record. However, to date, little information is available regarding potential global changes in the early hominin brain. The introduction of non-invasive imaging techniques opens up new perspectives for the study of hominin brain evolution...

INTRODUCTION: The late detection of developmental dysplasia of the hip (DDH) will remain a major concern in some parts of the world until effective screening programs become available. With late diagnosis comes the need for open surgical reduction. Surgery is invariably followed by a period of immobilisation in a spica cast to prevent postoperative displacement. The goal of this study is to evaluate the effect of double-leg spica as compared to single-leg spica, on the risk of displacement after unilateral open reduction of the hip...

Background: Isokinetic strength testing is an important tool in the evaluation of the physical capacities of athletes as well as for decision making regarding return to sports after anterior cruciate ligament (ACL) reconstruction in both athletes and the lay population. However, isokinetic testing is time consuming and requires special testing equipment. Hypothesis: A single-jump test, regardless of leg dominance, may provide information regarding knee extension strength through the use of correlation analysis of jump height and peak torque of isokinetic muscle strength...
