The hanging chin sign as a mortality predictor in geriatric patients at the emergency department: a retrospective cohort study.

Background: At the emergency department, there is a need for an instrument which is quick and easy to use to identify geriatric patients with the highest risk of mortality. The so- called 'hanging chin sign', meaning that the mandibula projects over one or more ribs on the chest X-ray, could be such an instrument. This study aims to investigate if the hanging chin sign is a predictor of mortality in geriatric patients admitted through the emergency department.

Embolization of the Geniculate Arteries Is an Effective Treatment of Recurrent Hemarthrosis Following Total Knee Arthroplasty That Can Be Safely Repeated.

Background: Recurrent hemarthrosis is a late complication in up to 1.6% of patients following total knee arthroplasty (TKA). In the absence of intrinsic coagulopathy, one etiology is bleeding of hypertrophic vascular synovium.

Intensive rehabilitation in selected hip fracture patients may optimize care efficiency: A retrospective comparison study.

Objective: To gather preliminary data on the effectiveness of intensive rehabilitation after hip fracture surgery, as provided in the Transfer Unit (TU) in Leiden, The Netherlands, compared with the effectiveness of rehabilitation in a regular nursing home. Intensive rehabilitation in the TU consists of physical therapy twice daily by dedicated medical staff and aims to shorten hospital stay and duration of rehabilitation, in order to increase the hospital admission capacity and reduce waiting lists for nursing homes.

Design: Retrospective cohort study.

Bone healing and mannose-binding lectin.

Non-union of a fracture is a phenomenon that may complicate bone healing. Consolidation of a fracture can be divided into three phases: inflammation, reconstruction, and remodeling. Both the complement system and the coagulation cascade interact at various steps throughout these phases.

Circulating bone morphogenetic protein levels and delayed fracture healing.

Objective: Despite adequate treatment 5-30% of bone fracture patients experience delayed union. During normal fracture union, bone morphogenetic proteins (BMPs) induce healing through a sequential cascade of events. Improved fracture healing after BMP-2 or -7 supplementation in patients with impaired fracture union suggests a deficiency of one or more of these factors.

[Von Meyenburg complexes in the liver: not metastases].

A 74-year-old woman underwent a laparotomy for a rectal carcinoma. Multiple lesions of the liver were discovered as incidental findings. Histopathology revealed that these were Von Meyenburg complexes (VMCs).
