Major Heel Reconstructions Through Small Incisions.

A variety of osteotomies on the calcaneus have been described in the past to adapt the shape of the calcaneus to specific needs. Newer osteotomy and fixation methods allow the procedure to be as minimally invasive as possible. Recent data suggest that the minimally invasive surgery (MIS) techniques allow for fewer complications, particularly with regard to wound healing.

Synthetic cartilage implant vs. first metatarsophalangeal arthrodesis for the treatment of hallux rigidus.

Background: This study evaluated the outcome of the Cartiva synthetic cartilage implant (SCI) in the treatment of hallux rigidus.

Methods: In the present retrospective matched case-control study, we compared 18 patients with Cartiva SCI (mean follow-up: 17.7 months) to 18 patients with metatarsophalangeal joint arthrodesis (mean follow-up: 20 months) using multiple function measures, along with four specified visual analog subscales for pain.

From symptom onset to ED departure: understanding the acute care chain for patients with undifferentiated complaints: a prospective observational study.

Background: For most acute conditions, the phase prior to emergency department (ED) arrival is largely unexplored. However, this prehospital phase has proven an important part of the acute care chain (ACC) for specific time-sensitive conditions, such as stroke and myocardial infarction. For patients with undifferentiated complaints, exploration of the prehospital phase of the ACC may also offer a window of opportunity for improvement of care.

Evaluation of an external foam column for product removal in aerated surfactin production processes.

In fermentation processes, severe foam formation may occur in aerated bioreactor systems caused by surface-active lipopeptides. Although they represent interesting compounds for industrial biotechnology, their property of foaming excessively during aeration may pose challenges for bioproduction. One option to turn this obstacle into an advantage is to apply foam fractionation and thus realize product removal as an initial downstream step.
