Objective: Epidemiological data on synchronous and metachronous lung metastases from colorectal cancer are scarce. The aim of this study was to determine trends in the incidence, treatment and survival in colorectal cancer with lung metastases in the general population. Design and patients: All cases of lung metastases from colorectal cancer registered in the Burgundy digestive cancer registry between 1976 and 2005 were included. Trends in the incidence of synchronous colorectal cancer lung metastases were estimated. A Cox model was used to analyse the risk of developing a metachronous metastasis. Multivariate analyses were performed using a relative survival model with proportional hazard applied to the net survival by interval. Results: Overall, 11.0% of patients had synchronous lung metastases. The frequency of synchronous lung metastases significantly increased for both sexes over time, with a nearly threefold increase between the periods 1976-1985 and 1996-2005. The overall 5-year cumulative risk of developing metachronous lung metastases was 5.8%. It did not significantly vary with time. Compared to colon cancer, rectal cancers had a higher risk of developing synchronous (OR: 2.80 (1.65-4.76)) and metachronous (OR: 2.63 (1.69-4.08)) lung metastases. Overall, 4.1%of synchronous lung metastases and 14.3%of metachronous lung metastases were resected for cure. The 3-year relative survival was 11.3% for synchronous lung metastases and 13.8% for metachronous lung metastases. It was, respectively, 53.0% and 59.2% after resection for cure. In multivariate analysis, the relative risk of death for the 1996-2005 period was about one fifth of that for the 1976-1985 period. Conclusions: The incidence of synchronous lung metastases increased over time, whereas the incidence of metachronous lung metastases remained stable. Lung metastases were more frequent in rectal cancer than in colon cancer. Unless surgical resection is possible, the prognosis for lung metastases remains very poor.

We describe our experience with a new system of patient-specific template called Personal Fit®, which is unique in shoulder surgery and used in combination with Duocentric® prosthesis. The reverse prosthesis's concept is the invention of Paul Grammont, developed with Grammont's team of Dijon University as from 1981, which led to the first reversed total shoulder prosthesis called Trumpet in 1985. The Duocentric® prosthesis developed in 2001 is the third-generation prosthesis, coming from the Trumpet and the second-generation prosthesis Delta® (DePuy). This prosthesis provides a novel solution to the notching problem with an inferior overhang integrated onto the glenoid baseplate. Personal Fit® system is based on reconstructing the shoulder joint bones in three dimensions using CT scan data, placing a landmark on the scapula and locating points on the glenoid and humerus. That will be used as a reference for the patient-specific templates. We study the glenoid position planned with Personal Fit® software relative to native glenoid position in 30 cases. On average, the difference between the planned retroversion (or anteversion in one case) and native retroversion was 8.6°. © 2013 Springer-Verlag.

Background: Adipose tissue releases angiogenic factors that may promote tumour growth. Objective: To determine whether body mass index (BMI), subcutaneous fat area (SFA) and visceral fat area (VFA) are associated with outcomes in patients given first-line bevacizumab-based treatment for metastatic colorectal cancer (MCC). Patients: CT was used to measure SFA and VFA in 120 patients with MCC who received bevacizumab-based treatment (bevacizumab group, n=80) or chemotherapy alone (chemotherapy group, n=40) as first-line treatment. Associations linking BMI, SFA and VFA to tumour response, time-to-progression (TTP) and overall survival (OS) were evaluated. Results: In the bevacizumab group, median follow-up lasted for 24 months (3-70). BMI, SFA and VFA values above the median (ie, high BMI, high VFA and high SFA) were significantly associated with absence of a response. TTP was shorter in patients with high BMI (9 vs 12 months; p=0.01) or high VFA (9 vs 14 months; p=0.0008). High VFA was associated with shorter OS (p=0.0493). By multivariate analysis, high VFA was independently associated with response, TTP and OS (HR=7.18, p=0.008, HR=5.79, p=0.005 and HR=2.88, p=0.027, respectively). In the chemotherapy group, median follow-up lasted for 30 months (4-84). BMI, SFA and VFA were not associated with response, TTP or OS. In the whole population, interaction between VFA and bevacizumab administration was significant for response (OR=3.31, p=0.005) and TTP (HR=1.64, p=0.022), thereby confirming the results. Conclusion: This study provides the first evidence that high VFA independently predicts a poorer outcome in patients given first-line bevacizumab-based treatment for MCC. However, this predictive biomarker needs to be validated in a different dataset.

Hepatic infarction is rare in hemolysis, elevated liver enzymes, and low platelets syndrome. We described a case of a 24-year-old woman who was admitted at week 17 of pregnancy with an antiphospholipid syndrome. Magnetic resonance imaging was the imaging modality of choice for diagnosing hepatic infarction, guiding treatment, ensuring the early detection of bleeding, and monitoring liver recovery. © 2010 Springer-Verlag.
