Hypermutation of the inactive X chromosome is a frequent event in cancer.

Mutation is a fundamental process in tumorigenesis. However, the degree to which the rate of somatic mutation varies across the human genome and the mechanistic basis underlying this variation remain to be fully elucidated. Here, we performed a cross-cancer comparison of 402 whole genomes comprising a diverse set of childhood and adult tumors, including both solid and hematopoietic malignancies.

Intraoperative subcutaneous wound closing culture sample: a predicting factor for periprosthetic infection after hip- and knee-replacement?

Introduction: It is unknown whether intraoperative subcutaneous wound closing culture samples (WCCS) are useful to predict periprosthetic joint infection (PJI).

Method: Here we prospectively followed 167 out of a total of 175 consecutive patients with primary total hip (THR) or knee replacement (TKR) between 01/2002 and 12/2002 for a mean follow-up period of 5 years; of those patients, n = 159 (96.8%) underwent WCCS.

[Total hip replacement for coxarthrosis following acetabular fracture. Significance of age and injury severity].

Aim: this study analyzed factors influencing prosthetic hip function after total hip replacement surgery (THR) including the initial acetabular fracture type, patient age, and the acetabular reconstruction component.

Material And Method: a total of 45 patients with secondary arthritis due to acetabular fracture and THR were prospectively selected from our total hip arthroplasty register between July 1999 and December 2005. The initial acetabular fracture was classified according to the AO system and the statistical analysis of the preoperative and postoperative Harris hip score (HHS) was correlated with age, type of fracture and acetabular reconstruction component.
