Monteggia equivalent fracture associated with Salter I fracture of the radial head.

Monteggia fracture is an infrequent lesion, which associates ulna fracture and radial head dislocation. Equivalent Monteggia can occur by associated lesions such as olecranon fracture or radial neck or head fracture. We report an unusual case of Monteggia equivalent lesion associating a fracture of the proximal third of the ulnar shaft and a growth plate fracture Salter I of proximal-radial physis and divergent displacement due to a bottle-opener effect of the radial head over the capitellum during trauma.

Tamponade following sternoclavicular dislocation surgical fixation.

The authors report a case of posterior sternoclavicular dislocation surgically reduced and stabilized with tenodesis, according to the Burrows technique completed by temporary wire fixation. The patient presented postoperative pericardiac tamponade appearing progressively from brachiocephalic blood vessels bleeding. Emergency drainage was surgically placed associated with removal of the material, thus curing the patient.

Spinosad affects chemical communication in the German cockroach, Blatella germanica (L).

Spinosad is a biopesticide, derived from fermentation by the soil-dwelling actinomycete, Saccharopolyspora spinosa, which is used to control a variety of insects. Spinosad kills a wide range of insect pests when ingested or topically applied, by overexciting the nervous system, yet is harmless to mammals and many predatory insects. Other modes of action of this insecticide have not been documented.

[Open leg fracture with Bacillus cereus infection].

Objective: To investigate leg fractures infected with Bacillus cereus in a traumatology-orthopedic ward of a university hospital.

Methods: All B. cereus strains isolated from patients with leg fracture hospitalized in the traumatology-orthopedic ward between 1995 and 2004 were included in this retrospective study.
