A primary intraosseous carcinoma (PIOC) is a squamous cell carcinoma arising within the  jawbone andshould be differentiated from a malignant ameloblastoma.  It  is not due to arising from an odontogenic cyst or tumor. The possibility of the lesion being  a metastasis fromanotherprimary site should be considered, and excluded by a careful history and examination. The diagnosis of a PIOC is ra...

It is difficult to study bone in vitro because it contains various cell types that engage in cross-talk. Bone biologically links various organs, and it has thus become increasingly evident that skeletal physiology must be studied in an integrative manner in an intact animal. We developed a model using local intraosseous small interfering RNA (siRNA) injection to rapidly assess the effects of a ...

BACKGROUND The purpose of this study was to determine the tibial fixation strength provided by different intraosseous soft tissue graft lengths within the tibial tunnel. METHODS Porcine tibial bones and digital flexor tendons were used for testing. Bone mineral densities of proximal tibial medial condyles were measured, and two-strand tendon bundles of 8 mm diameter were used. An intraosseous...

BACKGROUND Food allergy is the most common cause of anaphylaxis in children. Intramuscular delivery of epinephrine auto-injectors (EAI) is the standard of care for the treatment of anaphylaxis. We examined if children and adolescents at risk of anaphylaxis weighing 15-30 kg and >30 kg would receive epinephrine into the intramuscular space with the currently available EAI in North America and Eu...

BACKGROUND The etiology of navicular stress fractures is a topic of interest due to the implications in high-level athletes. Previous studies suggest an avascular zone in the central one-third of the bone as a potential causative factor. This study investigated the extraosseous and intraosseous arterial anatomy of the adult navicular. METHODS Sixty legs from 30 cadavers were amputated below t...

Background The aim of this study was to investigate the diameter, location, and frequency appearance posterior superior alveolar artery (PSAA), presence septa pathology in maxillary sinus on cone-beam computed tomography (CBCT) slices. Two hundred CBCT records were included study. patients divided into dentate, partially dentate edentulous. Methods diameter type PSAA (intrasinus-intraosseous-su...

J Korean Assoc Oral Maxillofac Surg 2012;38:166-70) Calcifying epithelial odontogenic tumor (CEOT) is a rarely reported benign tumor, accounting for 0.4-3% of all odontogenic tumors. Approximately 150 cases have been reported in the literature between 1958 and 2003. The age range of CEOT varies from 8 to 92 years with mean of 36.9 years, and the occurrence of the lesion in both genders is almos...

hereby we report a case of well-differentiated intraosseous osteosarcoma in the sacrum. a 32-year-old woman was admitted to our hospital with a low echo-level mass in the pelvis searched by ultrasound in a routine physical examination. radiographically, the mass was misdiagnosed as a benign bony tumor originating from the sacrum. the tumor was completely resected and pathological diagnosis was ...
