Choroidal osteoma with choroidal excavation and associated neovascular membrane: An OCT-angiography study.

2017

Abstract Clinical case A case is presented of a unilateral choroidal osteoma with choroidal excavation and associated neovascular membrane that was studied using OCT-angiography. The OCT and OCT-angiography revealed an area of choroidal excavation and an active neovascular membrane. Three doses of aflibercept were administered to the patient, which stabilized the neovascularisation. Discussion OCT-angiography was used to analyze the morphology of the superficial vascular network of the osteoma, as well as to monitor the evolution of the neovascular membrane.

Biological Causes of Anterior Knee Pain

2012

We review the pathophysiology of anterior knee pain in the young patient. Emphasis is placed on newer findings. We have developed what we call the “Neural Model” as an explanation for the genesis of anterior knee pain. We have demonstrated a neuroanatomical basis for PFPS in the young patient and the clinical observation that the lateral retinaculum may have a key role in the origin of this pain. According to our studies we hypothesize that periodic short episodes of ischemia in the lateral retinaculum could be implicated in the pathogenesis of anterior knee pain, at least in a subgroup of anterior knee pain patients, by triggering neural proliferation of nociceptive axons (substance P posi…

Root resorption caused by osteoma growth

2015

introduction. Osteoma is a benign and asymptomatic neoplasm, consisting of well-differentiated mature bone. The solitary osteoma may be classified as: peripheral when arising from the periosteum, central when arising from the endosteum and extraskeletal when arising in soft tissue. The etiology of osteoma is still unclear. Some reported cas- es did have a clear history of trauma; however, this was not the case in the majority of cases. Whereas peripheral osteomas are fairly easy to diagnose, central osteomas pose a more challenging diagnostic problem and need to be differentiated from other similar lesions of the jaws, such as central ossifying fibroma, osteoblastoma, cementoblas- toma and …

Professional diagnostic delay in osteosarcomas of the jaws

2020

A series of 20 consecutive patients with an osteosarcoma of the jaws has been evaluated with regard to possible professional diagnostic delay. When set at an arbitrarily chosen period beyond three months, professional delay occurred in 15 patients, the mean being 21 months and the median 11 months. In five of the 15 patients a wrong diagnosis has been rendered on the biopsy specimen, being fibrous dysplasia (2x), osteoma (2x) and, in case of palatomaxillary swelling, pleomorphic adenoma (1x). In the other ten patients the initial clinicoradiographic features were misleading and apparently not indicative of a malignancy, except for one patient in whom a distinct widening of the periodontal l…

Psammous desmo-osteoblastoma

1987

Fibro-osteo-cemental lesions of the jaw bones are a heterogeneous group of diseases which present problems in classification. Psammous desmo-osteoblastoma is one of four newly proposed entities (Makek 1983) and has until now been characterized by its light microscopic, clinical and radiological features. On electron microscopy this tumour exhibits fibroblastic (preosteoblastic), osteoblastic and osteocytic cells and a globular mineralization unlike the mineralization of the psammoma bodies. Immunohistological investigations with anti-osteonectin, a bone specific protein linking mineral to collagen, showed positive intracellular staining in all tumour cells and extracellular staining in the …

Nutrition-related health problems in a wealthy 17-18th century German community in Jelgava, Latvia.

2012

The aim of this research is to assess the presence of stress in a high status German population from Jelgava, Latvia. The skeletal material used in this study came from a recently excavated church cemetery, with most of the burials dating to the 17-18th centuries. In total, 108 individuals (80 adults and 28 non-adults) were analysed for evidence of scurvy, rickets/osteomalacia and anaemia. The presence of scurvy and healed rickets/osteomalacia could not be confirmed in any adult individual. Among non-adults, a possible diagnosis of scurvy was considered in six individuals, and active rickets was suggested in two others. Cribra orbitalia in adult and non-adult individuals also argued for the…
