30 patients with a transmural primary myocardial infarction conventionally treated, are explored by myocardial scintigraphy using thallium 201, and calculation of a lesional score (L.S) and angio-scintigraphy on the first day (D1) and at three weeks (D21). The results of these examinations are compared to those of coronography at D21. Anterior necroses present a myocardial fixation defect and a dysfunction of the left ventricle which are more severe than in inferior necroses. Patients with a marked fixation defect (L.S 2) at D1, present a low ejection fraction (EF) becoming significantly worse at D21. Coronary permeability is accompanied by an appreciable improvement of the myocardial fixation from D1 to D21 and a stability of EF. On the contrary, if the occlusion persists, the fixation defect is stable and the EF decreases significantly. In this study, the coronary permeability appears to be associated to a perservation of the ischemic myocardium which may only be demonstrated by knowing the evolution of the various parameters during the first three weeks of the infarction.

The posterior mandible is the primary area for occlusal function. However, long-term tooth loss in the posterior mandible often leads to rapid absorption of both buccal and lingual trabecular bone plates and subsequent atrophy of the alveolar ridge. This ultimately results in horizontal bone deficiencies that complicate achieving an optimal three-dimensional placement for dental implants.

Introduction: As the number of revision total knee arthroplasties (rTKA) continues to rise, there is increasing interest in the use of contemporary rotating hinge prostheses. These devices often incorporate porous cones to fill bone defects and enhance long-term fixation. This study evaluated the clinical and functional outcomes and survivorship in rTKA patients utilizing a rotating hinge prosthesis with flexible titanium (FT) cones, porous tantalum (PT) cones, or no cones.

Introduction: Necrotising soft tissue infection (NSTI) is an exceptionally dangerous infectious disease targeting soft tissues with high mortality as well as morbidity. The aim of reconstructive surgery after initial debridement is to maintain function as well as to achieve a satisfactory cosmetic result.
Presentation Of Case: A 50-year-old male presented with necrotising soft tissue infection on the thorax and left upper arm following mastectomy for breast cancer.
