Supernatant fluids from the cultures of bone marrow cells from 10 of 12 patients with multiple myeloma (MM) caused bone resorption in organ cultures of fetal rat calvaria. In four patients, the marrow cells were cultured with and without indomethacin (1 muM). The supernatant fluids from indomethacintreated marrow cultures caused significantly less bone resorption than supernatant fluids of cell...

The incidence of a metastatic tumor the calvaria is uncommon, but it has considerable impact in field neurosurgery. hematogenous spread was common leiomyosarcoma. Calvaria one most uncommon locations for this type cancer. A 70-year-old man with history rhabdomyosarcoma and thyroid cancer came parietal mass that rapidly enlarged, followed by sudden hemiparesis severe cognitive impairment. Head C...

Acrania is a rare foetal anomaly in which the calvaria absent, and meninges come into direct contact with amniotic fluid. most common acrania – exencephaly anencephaly spectrum, anincidence of 3.68 to 5.4 per 10,000 live births. We present case primigravida who presented for an ultrasound on account vaginal bleeding early cyesis. Transabdominal showed viable foetus at 13 weeks without calvaria,...

In order to test the effect of diphosphonates in inhibiting bone lysis induced by human tumors, neonatal mouse calvaria are cultured in sterile conditions in different media. Osteolysis is estimated by the amount of 45Ca released from bone to medium, the mice being given injections of 45Ca on their day of birth. An increased bone lysis is observed when calvaria are incubated in the same medium ...

background: it has been stated that the bone allografts from different tissue banks may lead to various amount of bone induction, so the aim of this study was to evaluate bone regeneration of three demineralized allografts both histologically and histomorphometrically in rabbits calvaria bone defects. materials and methods: in this double-blind randomized experimental animal study, 32 critical ...

We present 2 cases of isolated tumour the calvaria that underwent a different management but, unexpectedly, same very rare diagnosis primary diffuse large B-cell lymphoma cranial vault. Unfortunately, outcome was opposite due to numerous factors. discuss herein radiological and surgical options in light literature.
