Efficacy of subcutaneous injection of platelet-rich plasma in alopecia: A clinical and histological pilot study on a rat model with a six-month long-term follow-up experience.

Purpose: To assess the potential of platelet-rich plasma (PRP) subcutaneous injection of to treat alopecia and to evaluate local toxicity.

Materials-methods: Twelve Hairless rats were used. At D0, we performed systematic clinical examination and divided the rat back into four quadrants (Q).

Combined intra-tendinous injection of Platelet Rich Plasma and bevacizumab accelerates and improves healing compared to Platelet Rich Plasma in tendinosis: comprehensive assessment on a rat model.

Purpose: the aim of our study was to assess the potential of combined intratendinous injection of an anti-angiogenic drug: bevacizumab (AA) and Platelet Rich Plasma (PRP) to treat tendinopathy in a murine model of patellar and Achilles tendinopathy, and to evaluate its local toxicity.

Material And Method: twenty rats (80 patellar and Achilles tendons) were used for the study. We induced tendinosis (T+) in 80 tendons (patellar=40 and Achilles=40) by injecting under ultrasonography (US) guidance Collagenase 1® (day 0 = D0).

Lumbar artery pseudoaneurysm as a late complication of osteomyelitis with vertebral body destruction.

We report the case of a 79-year-old patient whose acute back pain revealed a 9-cm nonruptured lumbar artery pseudoaneurysm occurring 5 years after a vertebral body osteomyelitis that induced a significant vertebral destruction. She underwent an urgent percutaneous selective arterial embolization. Lumbar artery false aneurysm should, thus, be suspected as a possible etiology of any new painful symptoms in patients suffering from a chronic vertebral destructive disease.
