Crohn's disease with oral presenting signs masquerading as chronic osteomyelitis

Background: A case of Crohn's disease (CD) was diagnosed following recognition of oral and systemic signs and symptoms in a 19-year-old male patient. Methods: Clinical investigation utilized included blood tests (full blood count, electrolytes, urea, creatinine, liver function tests), computed tomogrphy scans, magnetic resonance imaging scans, oral biopsies, colonoscopy and biopsies of the terminal ileum and colon. Results: A diagnosis of CD was made which then allowed appropriate medical treatment to be initiated. Conclusion: The importance of a thorough medical history and full physical examination with appropriate investigations as dictated by clinical findings is demonstrated.

Structural studies in lead germanate glasses: EXAFS and vibrational spectroscopy

The Raman, IR absorption and EXAFS spectra at the Ge K-edge and Pb LIII-edge of eight lead germanate glasses, with general formula xPbO(1-x)GeO2 with x = 0.20, 0.25, 0.33, 0.40, 0.50, 0.53, 0.56 and 0.60, have been measured. The occurrence of [GeO6] units besides [GeO4] could not be deduced unambiguously from the data. The vibrational and EXAFS data agree with a progressive depolymerization of the network. Starting from all Ge atoms linked to four bridging oxygens in GeO2 (x = 0), the number of tetrahedral units with one or two non-bridging oxygens increases with x. At low content, Pb2+ ions act as modifiers in the germanate structure, but to a lesser extent than an equivalent number of alkaline ions. © 1993.
