Numerous studies have demonstrated significant associations between periodontal disease and many other diseases in living populations, and some studies have shown that individuals with periodontal disease are at elevated risks of mortality. Recent analysis of a medieval skeletal sample from London has also shown that periodontal disease was associated with increased risks of mortality in the pa...

Periosteal chondroma is a rare benign cartilage tumor located on the cortical bone, which may be mistaken clinically and histologically for other and more common tumors in this location. The current study reports the case of periosteal chondroma located in the distal femur of a 14-year-old female. A non-tender swelling, 5×4 cm in diameter, was identified on computed tomography, a radiological s...

Periosteal osteosarcoma (PO) is a rare primary malignant bone tumor and a variant of osteosarcoma. It is a surface lesion without evidence of medullary involvement. The radiologic appearance of periosteal osteosarcoma is a broad-based surface soft-tissue mass that causes extrinsic erosion of thickened underlying diaphyseal cortex and perpendicular periosteal reaction extending into the soft-tis...

OBJECTIVES To define the postoperative time interval required for elevated periosteum to readhere to the skull and regain its preoperative strength, and to evaluate whether fixation of the periosteum affects this interval or the strength of postoperative readhesion. DESIGN Prospective analysis of variance and covariance with repeated measures. SUBJECTS Thirty-six New Zealand white rabbits, ...

Periosteal osteosarcoma is a rare subtype of osteosarcoma. Wide surgical removal is the commonly used treatment-method algorithm. However, the limb-salvage procedure of periosteal osteosarcoma in the distal tibia is a technical challenge to orthopedic surgeons because of the scarcity of soft tissue and subcutaneous nature in the anteromedial aspect. We encountered a 16-year-old female patient w...

As part of our clinical tests on bone regeneration using cultured periosteal sheets, here, we prepared cultured periosteal sheets in two types of stem-cell culture media, STK1 and STK3. Human periosteum was expanded either in 1% human serum-supplemented STK1 for 28 days, in 1% human serum-supplemented STK1 for 14 days followed by 1% human serum-supplemented STK3 for 14 days (1% human serum-supp...

BACKGROUND Paralytic ectropion patients suffer from impairment of function and appearance of the lower eyelid and are at high risk of developing an exposure keratitis. A canthoplasty procedure can reduce the horizontal eyelid laxity and elevate the lower eyelid. We used a periosteal flap from the outer orbit to create a new canthal ligament. This study investigates the long-term outcomes of thi...

In the present study, the effect of successive milt collection was investigated on spermatological parameters and reproduction successes of wild and cultured endangered caspian brown trout. The milt collection was done 3 times with two weeks intervals. After milt collection, amount of milt was allocated for milt quality evaluation and reminders used for fertilization. According to results, in w...
