PURPOSE: To quantify the effect of osteoarthritis (OA) and total trapeziometacarpal (TMC) joint replacement on thumb kinematics during the primary physiological motions of the thumb. METHODS: We included 4 female patients with stage III TMC OA. A computed tomography-based markerless method was used to quantify the 3-dimensional thumb kinematics in patients before and after TMC joint replacement surgery with the Arpe implant. RESULTS: Trapeziometacarpal OA led to a marked decrease of internal rotation and abduction of the first metacarpal (MC1) during thumb flexion and a decrease of MC1 adduction during thumb adduction...

Inclusion of the central nervous system (CNS) in the course of chronic lymphocytic leukaemia (CLL) is rare. At the moment no risk factors or proven treatment methods are known. The disease is described both in its early phase and during its acceleration period, thus it has been suggested that there might be independent mechanisms influencing the development of this condition. As there are no unified diagnostic procedure algorithms each patient needs to be assessed individually. CLL can manifest mostly in elderly people, for whom a possibility of development of neurological disorders with their aetiology different from leukaemia, should also be taken into consideration...

Reconstruction of the anophthalmic socket allows the use of an ocular prosthesis and rehabilitation of facial appearance. Dermis-fat grafting is one option in volume augmentation of the anophthalmic socket and presents unique benefits, including increased surface area within the socket and the ability to grow with pediatric patients. Postoperative complications of this procedure are relatively common. Minor complications, such as graft hirsutism, keratinization, and conjunctival cysts or granulomas, are managed easily by observation or simple intervention...

Suraj Chavda, Liran Levin
Alveolar ridge augmentation can be completed with various types of bone augmentation materials (autogenous, allograft, xenograft & alloplast). Currently autogenous bone is labelled as the "gold standard" due to faster healing times and integration between native and foreign bone. No systematic review has currently determined whether there is a difference of implant success between various bone augmentation materials. The purpose of this paper was to systematically review comparative human studies of vertical and horizontal alveolar ridge augmentation comparing different types of bone graft materials (autogenous, allograft, xenograft & alloplast)...

Musculoskeletal modeling and marker based motion capture techniques are commonly used to quantify the motions of body segments, and the forces acting on them during human gait. However, when these techniques are applied to analyze the gait of people with lower limb loss, the clinically relevant interaction between the residual limb and prosthesis socket is typically overlooked. It is known that there is considerable motion and loading at the residuum-socket interface, yet traditional gait analysis techniques do not account for these factors due to the inability to place tracking markers on the residual limb inside of the socket...

Foreign body reactions in the oral cavity are relatively common, frequently resulting from iatrogenic causes. Depending on the nature of the foreign material, various microscopic patterns may be observed, causing diagnostic difficulties. Recognition of the ensuing unusual microscopic pattern, especially for cases in which the possibility of a foreign body reaction is not entertained in the clinical differential diagnosis, necessitates sufficient degree of suspicion, familiarization with the spectrum of microscopic appearances, and careful clinicopathologic correlation...

PURPOSE: To evaluate if an inorganic graft applied before implant insertion interferes with osseointegration. MATERIALS AND METHODS: The bilateral mandibular incisors of 12 rabbits were extracted. One of the sockets was randomly filled with an inorganic xenogenic bone graft, whereas the remaining socket was allowed to heal naturally and served as a control. After 60 days, titanium implants were inserted into healing areas. The animals were killed 60 days after. Bone depositions were marked with fluorochrome oxytetracycline, alizarin, and calcein and evaluated using confocal laser scanning microscopy...

We have read with great interest the article published in the August 2017 edition of the journal, titled Current-Evidence on the Socket-Shield Technique: A Systematic Review. The article appears to present the technique mostly in a negative light, supported by a review of the literature that in its selection of content and methodology is fraught with error.

We investigate efficient sensitivity analysis (SA) of algorithms that segment and classify image features in a large dataset of high-resolution images. Algorithm SA is the process of evaluating variations of methods and parameter values to quantify differences in the output. A SA can be very compute demanding because it requires re-processing the input dataset several times with different parameters to assess variations in output. In this work, we introduce strategies to efficiently speed up SA via runtime optimizations targeting distributed hybrid systems and reuse of computations from runs with different parameters...

The ball-and-socket ankle joint is a rare deformity characterized by the loss of concavity in the trochlear surface of the talus with rounding of the articular surfaces of the distal fibula and tibia. Frequently, tarsal coalitions, fibular hypoplasia, and shortening of the limb accompany this deformity. To date, no data have been reported on surgical treatment of lateral ankle joint instability and peroneal tendon dislocation concomitant with a ball-and-socket ankle joint. In the present study, we report the case of a 43-year-old male patient with right lateral ankle joint instability and peroneal tendon dislocation in a ball-and-socket ankle joint, with accompanying tarsal coalition...
