Several decades ago, a clinical condition that included severe bone overgrowth was described in a few patients in South Africa. The autosomal-recessive disease that later was named sclerosteosis was found to be caused by a mutation in the SOTS gene causing a lack of the protein sclerostin. This protein is produced by osteocytes and exerts its effect as an inhibitor of bone formation by blocking the Wnt signaling pathway. ⋯ Wnt signaling might also play an important role in fracture healing with substances that causes an upregulation of the Wnt pathway producing enhancement of the fracture healing process. Healing of experimental fractures in various animal models have shown improvement following subcutaneously administered anti-sclerostin antibody. While there are no published reports on the potential effect of systemically administered anti-sclerostin antibodies on fracture healing in humans.

Prognosis in patients with traumatic brain injury (TBI) and Glasgow Coma Scale (GCS) score of 3 is poor, raising concern regarding the utility of aggressive operative neurosurgical management. Our purpose was to describe outcomes in a propensity matched population with TBI and GCS3 treated with operative neurosurgical procedures of craniotomy or craniectomy (CRANI). ⋯ Survival was achieved in 65% of patients that underwent surgical intervention for subdural and epidural haematoma, despite a presenting GCS of 3. These results demonstrate prompt operative neurosurgical management of mass lesion is warranted for selected patients with a GCS of 3, contributing to a significant 4-fold survival benefit. In the absence of mass lesion the effect of immediate neurosurgery on outcomes is inconclusive.

To describe the case of a patient with a severe head injury at a depth of about 1000 m from the cave entrance in Bavaria, Germany, who received pre-hospital trauma care for 12 days until evacuation. ⋯ This case highlights several pitfalls of trauma care in complex SAR operations, which often rely on expert knowledge and are not yet evidence-based practice.

Elderly people, due to neurological conditions and muscular atrophy, present a greater propensity to falls and thus are very susceptible to hip fractures. Other variables, such as osteoporosis, may also be related to the etiopathogenesis of hip fractures, although osteoporosis is in fact a concurrent disease, and merely a coadjutant cause. Nonetheless, osteoporosis can make fracture patterns more severe and interfere with osteosynthesis. ⋯ Furthermore, increased crystal size, increased cortical porosity, reduced osteocyte lacunar density and an increased Ca/P ratio associated with higher concentrations of Ca and P were described in hip fracture patients compared to control patients. Osteocalcin/collagen type 1 expression ratio and enzymatic cross-link content in high-density bone was found to be significantly lower in hip fractures compared to controls. In conclusion, further research in bone mineral density and associated parameters are of interest to deepen the understanding of osteoporotic hip fractures.

Observational Study
Long-term follow-up of trauma patients before and after implementation of a physician-staffed helicopter: A prospective observational study.
The first Danish Helicopter Emergency Medical Service (HEMS) was introduced May 1st 2010. The implementation was associated with lower 30-day mortality in severely injured patients. The aim of this study was to assess the long-term effects of HEMS on labour market affiliation and mortality of trauma patients. ⋯ The implementation of HEMS was associated with a significant reduction in time on social transfer payments. No significant differences were found in involuntary early retirement rate, long-term mortality, or work ability.
