Pelvic Ring and Peritrochanteric Fractures in a Patient with Osteogenesis Imperfecta Treated Surgically: Case Report with a 5-Year Follow-Up.

BACKGROUND Osteogensis imperfecta (OI) is a rare disorder associated with brittle bones, skeletal deformities, short stature, and conductive hearing loss. It is caused by mutations in genes encoding collagen type I production and is associated with multiple fractures occurring during a patient's lifetime. Atypical fractures can occur without a history of previous injury or diagnosis.

Many RNA molecules undergo complex maturation, involving e.g. excision from primary transcripts, removal of introns, post-transcriptional modification and polyadenylation.

RNA-Puzzles: a CASP-like evaluation of RNA three-dimensional structure prediction.

We report the results of a first, collective, blind experiment in RNA three-dimensional (3D) structure prediction, encompassing three prediction puzzles. The goals are to assess the leading edge of RNA structure prediction techniques; compare existing methods and tools; and evaluate their relative strengths, weaknesses, and limitations in terms of sequence length and structural complexity. The results should give potential users insight into the suitability of available methods for different applications and facilitate efforts in the RNA structure prediction community in ongoing efforts to improve prediction tools.

[Nonunion of the lateral humeral condyle--operative treatment, case report].

The nonunion of the lateral humeral condyle is the most important complication in course of the treatment of the fractures lateral humeral condyle. The cause of the occurrence is the articular liquid penetration to the fracture site, minor blood supply of the fractured fragment based only on the vessels penetrating from the metaphysis, insufficient immobilization period and fragment relocation. The operative treatment of a condyle nonunion previously was performed cautiously because of the high risk of the condyle necrosis and the mild nature of the deformity.
