ABSTRACT
Lipomas are extremely common benign soft tissue tumors that are usually subcutaneous and asymptomatic. However, an intramuscular lipoma, occurring adjacent to the proximal radius, may easily cause paralysis of the posterior interosseous nerve because of a specific anatomical relationship of these structures in that area. In this report, we describe an unusual case of a 48-year-old-woman with a posterior interosseous nerve syndrome due to an intramuscular lipoma. The patient had good recovery after surgery and rehabilitation physiotherapy.
ABSTRACT
Obturator dislocation of the hip associated with ipsilateral femoral neck fracture is an unusual injury. We report a case of a 40-year-old man with such a combination of injuries which was treated with an open reduction and internal fixation. He has a good follow-up result. There was no evidence of avascular necrosis on radiographs after 3 years.
ABSTRACT
Giant cell tumour of the tendon sheath (GCTTS) is a slowly progressing benign tumour arising from synovial cells of tendon sheaths. It is one of the most common soft tissue tumours in the hand. We report a retrospective study of 27 proven GCTTS of the hand. The mean length of follow-up was 4.5 years (17 months-8.5 years). Radiographic findings are useful and may prove of great diagnostic value. The positive diagnosis was provided by the pathology examination after complete excision that was performed in all patients. The recurrence was noted in two surgically managed cases. The excision should be meticulous and complete in order to avoid recurrence.

Echinococciasis is a zoonotic infestation, which generally involves the liver and the lungs. Primary muscle hydatidosis is an uncommon finding. The authors report a case of primary hydatid cyst localized in the right long head of the biceps femoris of a 25-year-old woman. A wide excision of the cyst with a safety margin was performed. No recurrence has been detected after a 3-year follow-up period. The authors review the literature and discuss the MRI findings. The diagnosis of muscular hydatid cyst is done using clinical and radiological findings in endemic context.

The continued evolution of adhesive technology and materials has increased the application of composite materials for the direct and indirect restoration of posterior dentition. While these innovations cannot address every restorative challenge, such developments do allow clinicians to use conservative preparation designs and varying surface treatments in their efforts to achieve functional and aesthetic results. This discussion details the comprehensive clinical protocol required to use laboratory-fabricated resin systems for inlay/onlay restorations.

The evolution of aesthetic restorative materials has led to the development of new preparation designs and cementation protocols. While conventional cements were able to provide mechanical and macromechanical retention for restorations with limited aesthetic expectations, resin cements with micromechanical retention have been formulated as aesthetic alternatives. The objective of the present article is to establish the differences between conventional and adhesive crown cementation techniques, as well as to provide guidelines for reducing postoperative sensitivity and improving aesthetic and functional results.

In the anterior region, the successful replacement of a single tooth with an implant-supported restoration is one of the most difficult treatment options due to numerous functional and biological requisites. Such prostheses should also satisfy the increasing aesthetic demands of patients who expect the definitive restoration to mimic the natural dentition and their supporting gingival tissues. This article highlights the importance of the provisional restoration as the critical element for aesthetic success and gingival integration. Its perfect replication in the definitive restoration requires the use of optimized transference techniques.

While single-tooth replacement can be accomplished with predictability using implant therapy, this procedure is challenging in the anterior region where numerous criteria must be evaluated by the restorative team. The available height of bone, soft tissue volume, and three-dimensional position of the anticipated implant restoration are among the numerous concerns that must be addressed prior to the initiation of treatment. This article provides a comprehensive review for the selection and placement of implants in the aesthetic region and illustrates these principles with a case presentation.

The function in implant-supported restorations is now predictably achieved, and the emphasis has shifted to aesthetics. Simultaneously with this change in focus, the direction toward prosthetic restorations as the ultimate objective of implant procedures has evolved. The anticipated prosthesis now dictates the placement and angulation of the implant, thereby improving the function and, above all, the aesthetics of the final result. The purpose of this article is to discuss the concept of guidance for optimized management of hard and soft tissues, during the surgical procedure and during tissue healing. Particular attention is given to the reformation of the papillae.

Composite and ceramic restorations are well-accepted treatment modalities for anterior as well as posterior regions, and numerous systems are available. This article presents the historical development of tooth-colored restorations from their incipience in 1882 to the second generation laboratory composites of today. The causes of failures in the early ceramics are discussed, and the search to delineate the optimal qualities of ceramics is outlined, listing the improvements of each new generation. The inherent obstacle of ceramic brittleness is reviewed along with the specific requirements of preparation. The learning objective of this article is to present the development of tooth-colored restorations in a concise form and indicate the characteristics of the materials currently available.
