[Frequency of hyperlipasemia in patients with bone fractures on follow up at the Military General Hospital in camp Kokolo].

Introduction: the purpose of this study was to describe the profile of serum lipases in patients with bone fractures and to investigate the associated factors.

Methods: we conducted a cross-sectional study at the Kokolo Military General Hospital in Camp Kokolo (KMGHICK) from July to October 2013. All patients admitted with bone fractures who had agreed to take part in the study were included.

[Study of names and folklore associated with Mycobacterium ulcerans infection in various endemic countries in Africa].

The purpose of this article is to present names used for Mycobacterium ulcerans infection (Buruli ulcer) and explain their meanings in various African languages. Representations associated with the disease were also studied. The study approach involved qualitative analysis of information from interviews and literature.

Bone density and local growth factors in generalized osteoarthritis.

Osteoarthritis is usually considered to be a primary disorder of chondrocyte function with secondary changes in bones. However, a defect in the subchondral bone resulting in loss of its shock absorbing capacity could transfer the stress of loading directly to the articular cartilage with secondary changes in the cartilage. Review of histomorphometric and bone densitometric studies at sites of osteoarthritis at the hip or knee revealed that cartilage fibrillation could not be dissociated from bony changes even in the earliest stages of osteoarthritis and that subchondral trabeculae are thickened and more spaced in osteoarthritis.

Biochemical and density assessment of the new bone in late remodeling after callus distraction.

Biochemical changes in a canine bone-lengthening model were characterized 5 months after surgery. The mineral content and the total amount of EDTA-extractable noncollagenous proteins, insulin-like growth factor-I, and osteocalcin were determined for the lengthened callus, and a gradient density fractionation analysis of bone powder particles was performed. The results were compared with two other areas of the lengthened tibia and one region of the contralateral tibia.

Bone density and osteoarthritis.

Osteoarthritis (OA) is a physiologic imbalance, a "joint failure" similar to "heart failure" in which mechanical as well as constitutional factors play a role. The initiation and progression of cartilage damage are distinct phenomena. One of the mechanisms of initiation of OA is subchondral bone stiffness, often a part of generalized inherited increased bone density.
