[Foot injuries in the emergency room : three lesions that should not be missed].

Urgent consultations for foot injuries are common. Trauma injuries are often obvious, such as displaced or open fractures, dislocations, or tissue breakdown. However, they can also have a subtle presentation and still hide severe structural damage.

[Diagnosis and management of chronic osteomyelitis of long bones in adults].

Chronic osteomyelitis is an inflammatory process of the bone caused by an infectious agent. This condition leads to altered bone vascularization and thus to bone destruction and formation of necrotic bone fragments (sequestrum). The treatment of chronic osteomyelitis is primarily based on surgical management, which includes debridement of the sequestrum and sampling of bone tissue for microbiological analysis in order to initiate a targeted antibiotic therapy.

[Six pitfalls around the ankle sprains].

Ankle sprains are frequently encountered. They result most of the time in lesions of the lateral ligament complex. Nevertheless, in the context of an ankle sprains, more severe injuries including fracture of the lateral process of the talus, fracture of the base of the 5th metatarsal, tear of the medial ligament complex, lesion of the syndesmosis, sprain of the Chopart joint, and peroneal tendons luxation are potentially overlooked and, if treated inadequately, may be associated with poor functional outcome.

Measure of efficiency and knee isokinetic strength in bike messengers and non-cyclist athletes.

Background: Gross efficiency in cycling (GE) seems correlated with lower-body strength. This study investigated GE at four different pedaling rates and its relationship with an isokinetic strength test in bike messengers (BM) and experienced athletes non-bike messengers (NBM).

Methods: Eight BM and eight NBM completed a maximal incremental test to determine maximal aerobic power (MAP) and maximal oxygen consumption (V̇O2max).

[A numerical simulation of the aerodynamics of the nasal cavity].

We present the results of the numerical simulation of the flow in the nasal cavity, going from the tip of the nostril to the nasopharyngeal region. The volume of the nasal cavity, obtained from axial and coronal scans, takes into account the geometries of the nasal valve and turbinates. The simulation is carried out with the FLUENT code which solves the equations of fluid mechanics.
