Autologous Peripheral Blood Stem Cell Therapy for Chronic Achilles Tendinopathy: Report of Three Cases

@#The treatment of chronic Achilles tendinopathy (CAT) remains challenging. We report three cases of CAT treated with autologous peripheral blood stem cells (PBSCs), following principles developed for chondrogenesis of the knee joint. Outcome measurement with a minimum of one and a half years follow-up showed significant improvement of Victorian Institute of Sport Assessment-Achilles questionnaire (VISA-A) scores, with reduction of tendon thickness and inflammation on MRI scan.

Osteochondrogenesis with Autologous Peripheral Blood Stem Cells for Osteochondral Lesions of the Talus: Report of Five Cases

@#Osteochondral lesions of the talus (OLTs) may progress to ankle arthritis needing ankle arthroplasty or arthrodesis. We report five cases of OLTs treated along the principles developed for chondrogenesis of the knee joint with autologous peripheral blood stem cells (PBSCs), resulting in repair and regeneration of the bone and cartilage components. Improvement in Ankle Osteoarthritis Scale (AOS) scores with minimum two years follow-up showed statistical significance (p < 0.05).

Chondrogenesis with Autologous Peripheral Blood Stem Cells for End-Stage Ankle Arthritis: Report of Three Cases

@#End-stage ankle arthritis represents an “unmet medical need”, awaiting an appropriate time for joint arthroplasty or arthrodesis. We report three cases of end-stage ankle arthritis treated along the principles developed for chondrogenesis of the knee joint with autologous peripheral blood stem cells, resulting in reversal of the ankle arthritis. The improvement in clinical outcome measure scores (Ankle Osteoarthritis Scale total score) with a minimum two-year follow-up were comparable to total ankle replacement (TAR), arthroscopic ankle arthrodesis (AAA) and open ankle arthrodesis (OAA).

Chest wall seeding of nocardiosis as a complication of a percutaneous transthoracic needle biopsy

This paper highlights an uncommon complication of a percutaneous transthoracic needle biopsy (PTNB). A patient with rheumatoid arthritis who was on immune suppressive drugs underwent a PTNB of a lung nodule. The histology showed “organizing usual interstitial pneumonia-like changes.” Unfortunately, one month after the PTNB, she developed a large deep-seated chest wall abscess at the biopsy needle tract and the previously seen lung nodule was larger. Nocardiosis sp. was isolated from the chest wall abscess. The lung and chest wall lesions were resolved with Bactrium and Fluconazole. The final diagnosis was pulmonary nocardiasis complicated by chest wall seeding following the PTNB procedure.
