The development of calvarial bones is tightly co-ordinated with the growth of the brain and needs harmonious interactions between different tissues within the calvarial sutures. Premature fusion of cranial sutures, known as craniosynostosis, presumably involves disturbance of these interactions. Mutations in the homeobox gene Msx2 as well as the FGF receptors cause human craniosynostosis syndro...
Unilateral anophthalmia in a Holstein calf was examined morphologically. On the left side, a small cystic remnant of the eye ball (CRE) was present in the orbit. The CRE was adhered to the dura mater through an abnormal foramen formed in the orbital region of the cranial base. At this region of the left cerebral hemisphere, a porencephalic change was detected. Histologically, the pigment epithe...
We analysed the epidemiological data and clinical features of patients with prion diseases that had been registered by the Creutzfeldt-Jakob Disease Surveillance Committee, Japan, over the past 10 years, since 1999. We obtained information on 1685 Japanese patients suspected as having prion diseases and judged that 1222 patients had prion diseases, consisting of definite (n=180, 14.7%) and prob...
BACKGROUND Success with bone morphogenetic protein-2 (BMP-2) has been widely reported in the osseous reconstruction of large calvarial defects. These efforts have required enormous doses of BMP-2 and are not sufficiently refined to facilitate the detail-oriented repair required for intricate craniofacial structures. We have previously shown that inkjet-based bioprinting technologies allow for p...
The morphology of the dura mater and its relationship with the structures of the cavernous sinus were analyzed in five tufted capuchin monkeys (Cebus apella) using histological sections, showing that the walls of the cavernous sinus of this species are similar to those of other primates, including man. Except for the medial wall of the cavernous sinus, the remaining walls consist of two distinc...
The epidural space is seen in embryos at stage 17 (41 days) on the periphery of the primary meninx. During stage 18 (44 days) the dura mater proper appears and the epidural space is located between this meninx and the perichondrium and contains blood vessels. During the last week of the embryonic period (stages 20-23) the epidural space is evident around the circumference of the spinal cord. On...
Marjolin's ulcer, which was first described more than 1.5 centuries ago, involves a rare malignant transformation of chronic scar tissue or ulcer. Marjolin's ulcer invading the skull, dura mater and the brain is quite exceptional. A case is presented of a patient with a massive Marjolin's ulcer arising in chronic scarring of the scalp following a fire burn 57 years previously. The tumour had in...
