Non-traumatic myositis ossificans mimicking a malignant neoplasm in an 83-year-old woman: a case report

<p>Abstract</p> <p>Introduction</p> <p>Myositis ossificans is a benign, self-limiting condition that usually affects young, athletically active men. To the best of our knowledge, this case report describes the oldest recorded patient with myositis ossificans.</p> <p>Case presentation</p> <p>Our patient was an 83-year-old Japanese woman who presented with a one week history of a palpable mass in the left thigh. She had a history of surgery for transverse colon cancer and lung cancer at the ages of 73 and 80, respectively. Clinical and radiological examinations suggested a malignant neoplasm such as metastatic carcinoma or extraskeletal osteosarcoma. A diagnosis of myositis ossificans was made by core needle biopsy. Our patient was asymptomatic and had no recurrence at one year follow-up.</p> <p>Conclusion</p> <p>Clinicians should consider myositis ossificans as a possible diagnosis for a soft tissue mass in the limb of an older patient, thereby avoiding unnecessarily aggressive therapy.</p

Novel Non-invasive Management of Chronic Groin Pain from Fibrosed Contracted Inguinal Ligament

A 34-year-old male patient presented with the complaint of chronic pain in the left groin following left side testicular vein ligation for varicocele. Ilio-inguinal neurectomy and cremaster muscle division was done in another hospital for the pain but with no relief of pain. Patient on examination showed point tenderness in the left groin at the pubic tubercle. Finger Invagination test in the left was painful with severe tenderness. Investigation showed fibrosed contracted left distal inguinal ligament. Percutaneous Ultrasonographic (USG) guided inguinal ligament release and Platelet-Rich Plasma (PRP) injection relieved the pain completely. Post-procedure patient showed significant improvement of pain

A novel approach of harvesting concentrated plasma-rich fibrin (PRF) with increased platelet count

Objectives: Platelet-rich fibrin (PRF) is an autogenous biomaterial, considered as the second-generation platelet concentrates rich in blood cells and growth factors entrapped in the fibrin matrix, which makes it as an ideal material with wound healing abilities. Studies have reported high harvest of cells using anticoagulants but the present study employs two different protocols to efficiently separate the platelet-rich layer at low centrifugal forces without the use of anticoagulants. Methods and Materials: Blood samples were collected with the consent of 20 volunteer donors. Ten blood samples were tested in each of the protocols studied, that is, protocol 1–200 g for 8 min (higher rpm and time) and protocol 2–60 g for 5 min (lower rpm and time). From the 12 ml of blood samples collected, 2 ml of blood was utilized for whole blood study; the remaining 10 ml was transferred into falcon tubes subjected to different rpm.Results: The present study employs a novel method to investigate segregation of cell types following low-grade centrifugation. One milliliter sequential pipetting technique was used to analyze number of leukocytes and platelets following centrifugation at two different g-forces. The protocols followed in the present study had 2–3-fold increase leukocytes concentration and 10–12-fold increases in platelet concentrations in the layers than the whole blood sample without the use of anticoagulants. Conclusion: The study concludes that protocol 1 was more efficient in harvesting platelets with less concentration of leukocytes, which is considered more suitable for various medical applications
